Feedback
A mechanism of communication within a system in that the input signal generates an output response which returns to influence the continued activity or productivity of that system.
Feedback, Psychological
A mechanism of information stimulus and response that may control subsequent behavior, cognition, perception, or performance. (From APA Thesaurus of Psychological Index Terms, 8th ed.)
Feedback, Sensory
A mechanism of communicating one's own sensory system information about a task, movement or skill.
Knowledge of Results (Psychology)
A principle that learning is facilitated when the learner receives immediate evaluation of learning performance. The concept also hypothesizes that learning is facilitated when the learner is promptly informed whether a response is correct, and, if incorrect, of the direction of error.

Signal Transduction
The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.

Post-ingestive feedbacks and associative learning regulate the intake of unsuitable sterols in a generalist grasshopper. (1/3981)

Behavioural studies of the grasshopper Schistocerca americana were undertaken to identify the mechanisms that regulate the intake of dietary sterols. In the first experiment, grasshoppers were allowed to feed on spinach, a plant containing only unsuitable sterols; immediately after this first meal, a suitable or unsuitable sterol was injected into the haemolymph. Grasshoppers injected with unsuitable sterols had second meals on spinach that were significantly shorter than those of grasshoppers injected with suitable sterols, indicating that unsuitable dietary sterols are detected post-ingestively. In the second experiment, grasshoppers were fed food containing only unsuitable sterols and were then presented with glass-fibre discs containing different concentrations of a suitable sterol or sucrose only (the control). The results suggest that grasshoppers do not use a direct feedback operating on mouthpart chemoreceptors to regulate their intake of suitable sterols. In the third experiment, grasshoppers were presented with artificial diets containing different sterols and flavours, and feeding was observed over a sequence of meals. The results from both the first and last experiments suggest a role for associative learning in regulating the intake of unsuitable sterols.  (+info)

Association of snRNA genes with coiled bodies is mediated by nascent snRNA transcripts. (2/3981)

BACKGROUND: Coiled bodies are nuclear organelles that are highly enriched in small nuclear ribonucleoproteins (snRNPs) and certain basal transcription factors. Surprisingly, coiled bodies not only contain mature U snRNPs but also associate with specific chromosomal loci, including gene clusters that encode U snRNAs and histone messenger RNAs. The mechanism(s) by which coiled bodies associate with these genes is completely unknown. RESULTS: Using stable cell lines, we show that artificial tandem arrays of human U1 and U2 snRNA genes colocalize with coiled bodies and that the frequency of the colocalization depends directly on the transcriptional activity of the array. Association of the genes with coiled bodies was abolished when the artificial U2 arrays contained promoter mutations that prevent transcription or when RNA polymerase II transcription was globally inhibited by alpha-amanitin. Remarkably, the association was also abolished when the U2 snRNA coding regions were replaced by heterologous sequences. CONCLUSIONS: The requirement for the U2 snRNA coding region indicates that association of snRNA genes with coiled bodies is mediated by the nascent U2 RNA itself, not by DNA or DNA-bound proteins. Our data provide the first evidence that association of genes with a nuclear organelle can be directed by an RNA and suggest an autogenous feedback regulation model.  (+info)

Bcl-2 regulates amplification of caspase activation by cytochrome c. (3/3981)

Caspases, a family of specific proteases, have central roles in apoptosis [1]. Caspase activation in response to diverse apoptotic stimuli involves the relocalisation of cytochrome c from mitochondria to the cytoplasm where it stimulates the proteolytic processing of caspase precursors. Cytochrome c release is controlled by members of the Bcl-2 family of apoptosis regulators [2] [3]. The anti-apoptotic members Bcl-2 and Bcl-xL may also control caspase activation independently of cytochrome c relocalisation or may inhibit a positive feedback mechanism [4] [5] [6] [7]. Here, we investigate the role of Bcl-2 family proteins in the regulation of caspase activation using a model cell-free system. We found that Bcl-2 and Bcl-xL set a threshold in the amount of cytochrome c required to activate caspases, even in soluble extracts lacking mitochondria. Addition of dATP (which stimulates the procaspase-processing factor Apaf-1 [8] [9]) overcame inhibition of caspase activation by Bcl-2, but did not prevent the control of cytochrome c release from mitochondria by Bcl-2. Cytochrome c release was accelerated by active caspase-3 and this positive feedback was negatively regulated by Bcl-2. These results provide evidence for a mechanism to amplify caspase activation that is suppressed at several distinct steps by Bcl-2, even after cytochrome c is released from mitochondria.  (+info)

A strategy for enhancing the transcriptional activity of weak cell type-specific promoters. (4/3981)

Cell type- and tissue-specific promoters play an important role in the development of site-selective vectors for gene therapy. A large number of highly specific promoters has been described, but their applicability is often hampered by their inefficient transcriptional activity. In this study, we describe a new strategy for enhancing the activity of weak promoters without loss of specificity. The basic principle of this strategy is to establish a positive feedback loop which is initiated by transcription from a cell type-specific promoter. This was achieved by using a cell type-specific promoter to drive the simultaneous expression of the desired effector/reporter gene product and a strong artificial transcriptional activator which stimulates transcription through appropriate binding sites in the promoter. Using a VP16-LexA chimeric transcription factor, we show that this approach leads to a 14- to > 100-fold enhancement of both the endothelial cell-specific von Willebrand factor promoter and the gastrointestinal-specific sucrase-isomaltase promoter while maintaining approximately 30- to > 100-fold cell type specificity.  (+info)

Differential regulation of p21waf-1/cip-1 and Mdm2 by etoposide: etoposide inhibits the p53-Mdm2 autoregulatory feedback loop. (5/3981)

The Mdm2 protein is frequently overexpressed in human non-seminomatous germ cell tumours and transitional carcinoma of the bladder where it may contribute to tolerance of wtp53. Mdm2 forms an autoregulatory feedback loop with p53; the Mdm2 gene is responsive to transactivation by p53 and once synthesized the Mdm2 protein terminates the p53 response. We show here that the topoisomerase poison etoposide, like ultra violet irradiation, inhibits Mdm2 synthesis. Cytotoxic concentrations of etoposide (IC90 for > 3 h) result in inhibition of Mdm2 induction at both the RNA and protein level. Rapid apoptosis ensues. Global transcription is not inhibited: p21waf-1/cip1 and GADD45 expression increase in a dose dependent manner. Inhibition of Mdm2 synthesis depends on the continuous presence of etoposide, suggesting the DNA damage may prevent transcription. Downregulation of Mdm2 transcript occurs in cells expressing HPV16-E6 suggesting that inhibition of Mdm2 transcription is p53-independent. When cells are -treated with a pulse (1 h) of etoposide and reincubated in drug free medium, Mdm2 synthesis commences immediately after damage is repaired (3 h) and the p53 response is attenuated. Induction of apoptosis and loss of clonogenicity are 3-5-fold lower under pulse treatment conditions. This is the first observation of inhibition of Mdm2 transcription following treatment with topoisomerase (topo II) poisons, a feature that may be useful in tumour types where p53 is tolerated by overexpression of Mdm2.  (+info)

Reciprocal control of T helper cell and dendritic cell differentiation. (6/3981)

It is not known whether subsets of dendritic cells provide different cytokine microenvironments that determine the differentiation of either type-1 T helper (TH1) or TH2 cells. Human monocyte (pDC1)-derived dendritic cells (DC1) were found to induce TH1 differentiation, whereas dendritic cells (DC2) derived from CD4+CD3-CD11c- plasmacytoid cells (pDC2) induced TH2 differentiation by use of a mechanism unaffected by interleukin-4 (IL-4) or IL-12. The TH2 cytokine IL-4 enhanced DC1 maturation and killed pDC2, an effect potentiated by IL-10 but blocked by CD40 ligand and interferon-gamma. Thus, a negative feedback loop from the mature T helper cells may selectively inhibit prolonged TH1 or TH2 responses by regulating survival of the appropriate dendritic cell subset.  (+info)

Randomised controlled trial of effect of feedback on general practitioners' prescribing in Australia. (7/3981)

OBJECTIVE: To evaluate the effect on general practitioners' prescribing of feedback on their levels of prescribing. DESIGN: Randomised controlled trial. SETTING: General practice in rural Australia. PARTICIPANTS: 2440 full time recognised general practitioners practising in non-urban areas. INTERVENTION: Two sets of graphical displays (6 months apart) of their prescribing rates for 2 years, relative to those of their peers, were posted to participants. Data were provided for five main drug groups and were accompanied by educational newsletters. The control group received no information on their prescribing. MAIN OUTCOME MEASURES: Prescribing rates in the intervention and control groups for the five main drug groups, total prescribing and potential substitute prescribing and ordering before and after the interventions. RESULTS: The intervention and control groups had similar baseline characteristics (age, sex, patient mix, practices). Median prescribing rates for the two groups were almost identical before and after the interventions. Any changes in prescribing observed in the intervention group were also seen in the control group. There was no evidence that feedback reduced the variability in prescribing nor did it differentially affect the very high or very low prescribers. CONCLUSIONS: The form of feedback evaluated here-mailed, unsolicited, centralised, government sponsored, and based on aggregate data-had no impact on the prescribing levels of general practitioners.  (+info)

Inhibition of cellular growth by increased guanine nucleotide pools. Characterization of an Escherichia coli mutant with a guanosine kinase that is insensitive to feedback inhibition by GTP. (8/3981)

In Escherichia coli the enzyme guanosine kinase phosphorylates guanosine to GMP, which is further phosphorylated to GDP and GTP by other enzymes. Here I report that guanosine kinase is subject to efficient feedback inhibition by the end product of the pathway, GTP, and that this regulation is abolished by a previously described mutation, gsk-3, in the structural gene for guanosine kinase (Hove-Jensen, B., and Nygaard, P. (1989) J. Gen. Microbiol. 135, 1263-1273). Consequently, the gsk-3 mutant strain was extremely sensitive to guanosine, which caused the guanine nucleotide pools to increase dramatically, thereby initiating a cascade of metabolic changes that eventually led to growth arrest. By isolation and characterization of guanosine-resistant derivatives of the gsk-3 mutant, some of the crucial steps in this deleterious cascade of events were found to include the following: first, conversion of GMP to adenine nucleotides via GMP reductase, encoded by the guaC gene; second, inhibition of phosphoribosylpyrophosphate synthetase by an adenine nucleotide, presumably ADP, causing starvation for histidine, tryptophan, and pyrimidines, all of which require PRPP for their synthesis; third, accumulation of the regulatory nucleotide guanosine 5',3'-bispyrophosphate (ppGpp), a general transcriptional inhibitor synthesized by the relA gene product in response to amino acid starvation.  (+info)

N2 - Sensory disturbance is very common following stroke and may exacerbate a patients functional impairment, even if the patient has good motor function. For instance, patients with sensory disturbances will often grip an object with excessive or underestimated pinch pressure, because they do not receive the appropriate sensory feedback and must rely only on visual feedback. In this study, we developed a sensory feedback system that used cutaneous electrical stimulation for patients with sensory loss. In the system, electrical stimulation is modulated by the strength of pinch pressure and the patients are able to identify their fingertip pinch pressure. To evaluate the efficacy of the system, a clinical case study was ...

Tubuloglomerular feedback - WikipediaTubuloglomerular feedback - Wikipedia
In the physiology of the kidney, tubuloglomerular feedback (TGF) is a feedback system inside the kidneys. Within each nephron, information from the renal tubules (a downstream area of the tubular fluid) is signaled to the glomerulus (an upstream area). Tubuloglomerular feedback is one of several mechanisms the kidney uses to regulate glomerular filtration rate (GFR). It involves the concept of purinergic signaling, in which an increased distal tubular sodium chloride concentration causes a basolateral release of adenosine from the macula densa cells. This initiates a cascade of events that ultimately brings GFR to an appropriate level. The kidney maintains the electrolyte concentrations, osmolality, and acid-base balance of blood plasma within the narrow limits that are compatible with effective cellular function; and the kidney participates in blood pressure regulation and in the maintenance of steady whole-organism water volume Fluid flow through the nephron must be kept within a narrow range ...

CiteSeerX - Active Feedback in Ad Hoc Information RetrievalCiteSeerX - Active Feedback in Ad Hoc Information Retrieval
CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Information retrieval is, in general, an iterative search process, in which the user often has several interactions with a retrieval system for an information need. The retrieval system can actively probe a user with questions to clarify the information need instead of just passively responding to user queries. A basic question is thus how a retrieval system should propose questions to the user so that it can obtain maximum benefits from the feedback on these questions. In this paper, we study how a retrieval system can perform active feedback, i.e., how to choose documents for relevance feedback so that the system can learn most from the feedback information. We present a general framework for such an active feedback problem, and derive several practical algorithms as special cases. Empirical evaluation of these algorithms shows that the performance of traditional relevance feedback (presenting the top K documents) is

Homeostasis: positive/ negative feedback mechanisms : Anatomy & PhysiologyHomeostasis: positive/ negative feedback mechanisms : Anatomy & Physiology
Hey Jennie. I see your point of view and understand why it can be confusing. The reason wound healing is considered a positive feedback mechanism is because the output enhances the original stimulus. If a cut occurs, the body sends platelets and cells to the site. The platelets and cells fight invading pathogens and produce a clot. When the clot forms and the wound heals, the inflammation response and output end. Negative feedback changes a variable back to its original value and is constantly adjusting within the body. If your temperature is to high, a negative feedback loop works to lower it. If your temperature is low, it will bring it back up. Its a balancing act. Positive feedback only occurs in certain situations and has an ending, it does not constantly adjust. If you get a cut, a positive feedback loop works to heal it, then it stops. If you go into labor, the loop continues until you deliver, then its over and you go back to your original state. Think if you werent pregnant but felt ...

Combined T(3)/T(4) therapy--In thyroidectomized patients, the L-T(4)-only replacement doses needed to normalize plasma T(3) or average tissue T(3) were 145 microg L-T(4)/day or 165 microg L-T(4)/day, respectively. The combined T(4) + T(3) dosing needed to normalize both plasma and tissue T(3) levels was 105 microg L-T(4) + 9 microg T(3) per day. For all three regimens, simulated mean steady-state plasma thyroid-stimulating hormone (TSH), T(3), and T(4) was within normal ranges (TSH: 0.5-5 mU/L; T(4): 5-12 microg/dL; T(3): 0.8-1.9 ng/mL).

Tailored feedback was rated as more relevant, and was more likely to be shown to the GP than the generic feedback. Given that the tailored feedback included personalised risk factor information, it is not surprising that it was rated as more relevant. Almost two-thirds of participants given the tailored feedback indicated that they either showed the feedback to their GP or it gave them some ideas about what to ask the doctor, compared to less than half of those who received generic feedback. Anecdotally, the tailored feedback prompted a greater response from participants than the generic feedback, including several who were surprised by their recommended healthy weight, and one participant who commented that seeing her depression score prompted her to bring this up with her GP. However, participants did not rate the tailored feedback as any more likely to help them improve their health, or any easier to understand, than the generic feedback..

Feedback loops, both positive and negative are embedded in the Mitogen Activated Protein Kinase (MAPK) cascade. In the three layer MAPK cascade, both feedback loops originate from the terminal layer and their sites of action are either of the two upstream layers. Recent studies have shown that the cascade uses coupled positive and negative feedback loops in generating oscillations. Two plausible designs of coupled positive and negative feedback loops can be elucidated from the literature; in one design the positive feedback precedes the negative feedback in the direction of signal flow and vice-versa in another. But it remains unexplored how the two designs contribute towards triggering oscillations in MAPK cascade. Thus it is also not known how amplitude, frequency, robustness or nature (analogous/digital) of the oscillations would be shaped by these two designs. We built two models of MAPK cascade that exhibited oscillations as function of two underlying designs of coupled positive and negative

Game design: an object lesson in seeking and receiving feedback | New Zealand Council for Educational ResearchGame design: an object lesson in seeking and receiving feedback | New Zealand Council for Educational Research
Taking a playcentric approach in a game-designing classroom might mean, as a student game designer, asking your classmates to play your game and give you feedback in a structured way. To get constructive feedback, you might ask your classmates to use sentence starters such as I like and I wonder and what if?. It also means learning how to listen and take on board their feedback or suggestions. These are examples of practices we saw in some of the primary and intermediate Games for Learning classrooms. By practising this process regularly, students got better at both giving and receiving thoughtful, constructive feedback. In one Year 7-8 classroom, students were facilitating the whole feedback process themselves, no longer needing the teacher to run it.. In a Year 6 classroom, in a different school, each student brainstormed as many ideas as they could for a game they would like to design. Then they took their ideas around the classroom on a speed date to get rapid feedback from peers. ...

In a mobile communication system, receivers measure channel characteristics using a received reference channel signal. The receivers determine a weight which has orthogonality with respect to each of a preset number of weight vectors in the mobile communication system and has the highest signal-to-interference-and-noise ratio, and feedback the weight and the corresponding signal-to-interference-and-noise ratio to the transmitter. The transmitter interprets the feedback information output from the receivers and determines receivers having feedback information which are orthogonal to each other and have the maximum throughput as an addition capacity when transmitted simultaneously, and determines weights based on the feedback information of the receivers having the maximum throughput. By applying the determined weights to the antennas using a well-known beam forming scheme, data can be transmitted to each of the determined receivers. Therefore, the

11. FEEDBACK ACTIONS OF GONADAL STEROIDS11. FEEDBACK ACTIONS OF GONADAL STEROIDS
In rainbow trout, bilateral castration at any stage of the testicular cycle, including the, period when the testes are inactive, increases plasma GtH levels (Billard, Richard and Breton, 1.976, 1977; Billard, 1978a). These results indicate that the negative feedback action of testicular steroids on GtH secretion occurs at all stages in the breeding cycle. Sex steroids are taken up and sequestered in the pituitary, the NPO, the nucleus lateralis tuberis (NLT), the nucleus recessus lateralis and other locations in the brain in many species of fishes, suggesting that a number of sites in the brain can serve as loci for feedback action of sex steroids (Kim. et al., 1978; Peter and Crim, 1979). In the sexually mature female goldfish, serum GtH levels increase markedly following implantation of antiestrogens in the pituitary, whereas similar implants in the NLT area result only in a modest GtH increase and have no effect when implanted elsewhere (Billard and Peter, 1977). Thus the NLT and pituitary ...

The invention relates to a device for the representation and determination of the rigidity of materials, by means of which measured physical values can be represented at a vicinity distant from the place of measurement and above all by means of a tactile representation, in other words, using the sense of touch. According to the invention, a force feedback system has been developed which permits the user or operator to gain a feeling for the mechanical rigidity value. The value for rigidity, measured for example for medical purposes by endoscope or arthroscope, controls the pressure found in an external touch cushion (2), by means of one of the voltages (U), given by an analytical device recording the appropriate test region. The rigidity of the cushion (2) thus gives an equivalent feel to the measured rigidity of the material under evaluation, or the biological probe. In the above rigidity transmitter (1) a pressure (P) is generated in a closed pressure system by means of an input converter (3) and

Joel Emers AbstractJoel Emers Abstract
In general, the prediction process is one of identifying the current state of the system, and making a prediction for some as yet uncomputed value based on that state. Prediction accuracy is improved by learning what is a good prediction for that state using a feedback process at the time the predicted value is actually computed. While there have been a number of efforts to formally characterize this process, we have taken the approach of providing a simple algebraic-style notation that allows one to express this state identification and feedback process. This notation allows one to describe a wide variety of predictors in a uniform way. It also facilitates the use of an efficient search technique called genetic programming, which is loosely modeled on the natural evolutionary process, to explore the design space. In this paper we describe our notation and the results of the application of genetic programming to the design of branch and indirect jump predictors. ...

A newly discovered molecular feedback process may protect the brain against Alzheimers - Healthcanal.com : Healthcanal.comA newly discovered molecular feedback process may protect the brain against Alzheimers - Healthcanal.com : Healthcanal.com
Ready to ship: Within cells displaying features of Alzheimers, the researchers found high concentrations of WAVE1 and the amyloid-β precursor protein within the Golgi, an organelle in which proteins are packaged for shipping. These appear in the cell above as bright, yellow clusters.. Our discovery centers on a protein called WAVE1, which we found to be important in the production of amyloid-β. The reduction of WAVE1 appears to have a protective effect against the disease, says study author Paul Greengard, Vincent Astor Professor and head of the Laboratory of Molecular and Cellular Neuroscience. When levels of amyloid-β rise, there is an accompanying increase in another molecule, AICD, which reduces the expression of WAVE1. This has the effect of reducing the production of amyloid-β.. By targeting steps within this newly discovered pathway, he adds, it may be possible to develop drugs to reduce amyloid-β that potentially could be used to either treat or prevent Alzheimers ...

Feedback control of nonlinear dissipative systems by finite determining parameters - A reaction-diffusion paradigmFeedback control of nonlinear dissipative systems by finite determining parameters - A reaction-diffusion paradigm
We introduce here a simple finite-dimensional feedback control scheme for stabilizing solutions of infinite-dimensional dissipative evolution equations, such as reaction-diffusion systems, the Navier-Stokes equations and the Kuramoto-Sivashinsky equation. The designed feedback control scheme takes advantage of the fact that such systems possess finite number of determining parameters (degrees of freedom), namely, finite number of determining Fourier modes, determining nodes, and determining interpolants and projections. In particular, the feedback control scheme uses finitely many of such observables and controllers. This observation is of a particular interest since it implies that our approach has far more reaching applications, in particular, in data assimilation. Moreover, we emphasize that our scheme treats all kinds of the determining projections, as well as, the various dissipative equations with one unified approach. However, for the sake of simplicity we demonstrate our approach in this

Phosphorylation of NEUROG3 Links Endocrine Differentiation to the Cell Cycle in Pancreatic Progenitors Scientists demonstrated that neurogenin 3 (NEUROG3) is phosphorylated within the nucleus on serine 183, which catalyzes its hyperphosphorylation and proteosomal degradation. During progression through the progenitor cell cycle, NEUROG3 phosphorylation is driven by the actions of cyclin-dependent kinases 2 and 4/6 at G1/S cell-cycle checkpoint.

Background: Murine double minutes-2 (MDM2) protein plays a key role in physiological processes like growth arrest, senescence and apoptosis. MDM2 negatively regulates key proteins like p53 by inhibiting its transcriptional activity and promoting its proteosomal degradation through ubiquitinylation. In turn, the MDM2 expression is regulated in part by a p53-responsive promotor. This negative feedback control mechanism assures that both p53 and MDM2 are kept at very low levels in proliferating cells. However, in about half of all human tumors, the normal regulation of p53 might be disrupted through direct overexpression of MDM2 caused by e.g. MDM2 gene amplification or a T to G substitution (SNP309) in the promotor region of MDM2. High resolution melting analysis (HRMA) provides a valid approach to efficiently detect DNA mutations. The current study aimed at validating and implementing HRMA for screening of colorectal cancer patients (CRC) to detect MDM2 promotor SNP309. Pyrosequencing was used to ...

Serum levels of nutrients may vary dramatically with time, but skin tissues may average such nutrition over time. Skin and other tissues may be scanned with light to produce accurate measurements of carotenoids or other nutrients accumulated in the skin based on the Raman scattering affect of those nutrients in the skin.

Evaluation and feedback in supervisionEvaluation and feedback in supervision
The guidelines and suggestions from these resources are summarized in the following list of effective evaluation practices:. 1. Clearly communicate evaluation criteria to supervisees and develop a mutually agreed upon written contract reflecting these criteria.. 2. Identify and communicate supervisee strengths and weaknesses. The Ethical Guidelines for Counsellor Supervisors (ACES, 1993) recommend that supervisors provide supervisees with ongoing feedback on their performance. This performance feedback establishes for supervisees a clear sense of what they do well and which skills need to be developed. Supervisee strengths and weaknesses can be evaluated in terms of process, conceptual, personal, and professional skills (Bernard R Goodyear, 1992, p. 42).. 3. Use constructive feedback techniques during evaluations. Supervisees are more likely to hear corrective feedback messages when these are preceded by positive feedback, focussed on observable behaviours, and are delayed until a positive ...

Frontiers | Homeostatic Control of the Thyroid-Pituitary Axis: Perspectives for Diagnosis and Treatment | EndocrinologyFrontiers | Homeostatic Control of the Thyroid-Pituitary Axis: Perspectives for Diagnosis and Treatment | Endocrinology
The long-held concept of a proportional negative feedback control between the thyroid and pituitary gland requires reconsideration in the light of more recent studies. Homeostatic equilibria depend on dynamic interrelationships between thyroid hormones and pituitary thyrotropin (TSH). They display a high degree of individuality, thyroid-state-related hierarchy and adaptive conditionality. Molecular mechanisms involve multiple feedback loops on several levels of organization, different time scales and varying conditions of their optimum operation, including a proposed feedforward motif. This supports the concept of a dampened response and multistep regulation, making the interactions between TSH, FT4 and FT3 situational and mathematically more complex. As a homeostatically integrated parameter, TSH becomes neither normatively fixed nor a precise marker of euthyroidism. This is exemplified by the therapeutic situation with L-thyroxine (L-T4) where TSH levels defined for optimum health may not apply

Electronic Feedback : pedagogical considerations for the implementation of softwareElectronic Feedback : pedagogical considerations for the implementation of software
As university lecturers, we often struggle to provide our students with good quality feedback in a consistent manner. This is usually caused by the increasing imbalance in teacher-student ratios (Hounsell et al., 2008), as well as the pressure of academic life and the lack of time (Sadler, 2010). In addition, assessment practices should be transparent enough to ensure all students are evaluated in a similar way (ODonovan et al., 2004), especially when different instructors teach different groups of students taking the same course. This paper, which focuses on designing a feedback scheme that helps instructors to provide good quality feedback in a consistent manner, begins with a needs analysis based on the authors experience as an instructor of academic writing in English. A literature review follows, focusing on: (a) the scholarship on feedback in higher education; and (b) the research on the use of technology for the provision of feedback. Finally, a feedback scheme is presented, and some ...

Feedback - Academic KidsFeedback - Academic Kids
In biological systems such as organisms, ecosystems, or the biosphere, most parameters must stay under control within a narrow range around a certain optimal level under certain environmental conditions. The deviation of the optimal value of the controlled parameter can result from the changes in internal and external environments. A change of some of the environmental conditions may also require change of that range to change for the system to function. The value of the parameter to maintain is recorded by a reception system and conveyed to a regulation module via an information channel. Biological systems contain many types of regulatory circuits, among which positive and negative feedbacks. Positive and negative dont imply consequences of the feedback have positive or negative final effect. The negative feedback loop tends to slow down a process, while the positive feedback loop tends to accelerate it. Feedback and regulation are self related. The negative feedback helps to maintain ...

Process operations often involve transitions between operating modes, which are typically described by their own dynamic models, constraints and specifications. Developing a formal theoretical framework and efficient computational tools to deal with such operational issues pose a formidable challenge. In the paper, we give an overview of recent key developments in this direction, involving (i) modeling of hybrid systems, exhibiting both continuous and discrete dynamics, to rigorously represent complex operations, and (ii) parametric programming mathematical and computational tools, to design optimal feedback control laws for constrained linear dynamic systems, in the context of model predictive control principles. Applications to a wide range of industrial problems will be discussed ...

Avoiding Bias In Your UX Feedback - Smashing Magazine | WebberoAvoiding Bias In Your UX Feedback - Smashing Magazine | Webbero
You know that user feedback is crucial - after all, your users will decide whether your app succeeds or not - but how do you know whether users are being fair and objective in their feedback? We can tell you: They wont be. All of your users will be giving you biased feedback. They cant help it. When soliciting and listening to user feedback, you will inevitably run into bias on both sides of the coin: Biases will influence the people providing feedback, and your own biases will influence the way you receive that feedback. Its important to be aware of this, especially when reviewing comments about your user experience (UX). Accurate and unbiased feedback is essential to developing the best possible version of your app1. Although you cant erase your own biases (or those of your users), you can take steps to overcome common biases once you know what they are and how they might appear. The next time you ask your users for input, keep bias in mind and evaluate how you respond to users comments. Is your

PERFORMANCE FEEDBACK AND RISK TAKING by Junyon ImPERFORMANCE FEEDBACK AND RISK TAKING by Junyon Im
Prior research on performance feedback has focused on the direct impact of performance feedback on risk taking (Lim & McCann, 2013) and paid little attention to the role of contextual factors. In particular, there are few empirical studies that examine how performance feedback and institutions interplay in risk taking of organizations. This study aims to fill this gap by investigating the role of organization-level institutional logics and state-level institutions in a microfinance industry. Institutions arise as a result of human beings continuous efforts to deal with uncertain environments (North, 1990; Scott, 1995). Thus, individual and organizational actors are affected by institutions, and different institutions can be a source of heterogeneity of organizational behavior (Peng, 2003). This suggests that the impact of performance feedback on risk taking can be affected by institutional factors. And, microfinance industry provides a good setting to investigate this issue.

Method and apparatus for offsetting baseline portion of oximeter signal - Patent # 4892101 - PatentGeniusMethod and apparatus for offsetting baseline portion of oximeter signal - Patent # 4892101 - PatentGenius
A feedback control system is disclosed for use in processing signals employed in pulse transmittance oximetry. The signals are produced in response to light transmitted through, for example, a finger at two different wavelengths. Each signal includes a slowly varying baseline component representing the relatively fixed attenuation of light produced by bone, tissue, skin, and hair. The signals also include pulsatile components representing the attenuation produced by the changing blood volume and oxygen saturation within the finger. The signals are processed by the feedback control system before being converted by an analog-to-digital (A/D) converter (72) for subsequent analysis by a microcomputer (16). The feedback control system includes a controllable offset subtractor (66), a programmable gain amplifier (68), controllable drivers (44) for the light sources (40, 42), and the microcomputer (16). The microcomputer (16) receives signals from the offset

Predictable and unpredictable behaviour « RealClimatePredictable and unpredictable behaviour « RealClimate
Curry also introduces a potential paradox in her report when she emphasises natural variations. The magnitude of natural temperature variation are regulated by feedback processes and have physical causes. The climate sensitivity also involve such feedback processes. Any feedback process based on temperature will act on both natural and forced changes in the temperature. If such feedbacks result in pronounced natural temperature variations, they also imply that the climate sensitivity is high. Examples of such feedbacks include increased atmospheric humidity and reduced snow/ice cover. Processes involving clouds are more uncertain, but they too are likely to be affected by temperature (convection) and act to modify the climatic response.. Natural variations may arise from both variations in the climatic state (eg ENSO, NAO, and PDO) or from external causes, such as changes in the sun and volcanic eruptions. There are also feedbacks relevant to forced variation as well as internal variability ...

Patent US5118997 - Dual feedback control for a high-efficiency class-d power amplifier circuit - Google PatentsPatent US5118997 - Dual feedback control for a high-efficiency class-d power amplifier circuit - Google Patents
A dual feedback control system for a Class-D power circuit maximizes efficiency by controlling the magnitude and phase angle of the resonant load circuit using two separate feedback loops. The first feedback loop changes the value of a first variable capacitor in response to difference in magnitude between the actual load impedance and the desired load impedance. The second feedback loop changes the value of a second variable capacitor in response to the phase difference between the actual phase angle and the desired phase angle. In this way, the real and imaginary components of the load impedance are controlled so that the Class-D circuit is in tune, and hence efficiency is maximized, over a wide range of load impedances. The dual feedback control of the present invention may be advantageously employed in the ballast of an electrodeless HID lamp system.

The Effect of Negative Feedback Loops on the Dynamics of Boolean Networks - RedorbitThe Effect of Negative Feedback Loops on the Dynamics of Boolean Networks - Redorbit
By Sontag, Eduardo Veliz-Cuba, Alan; Laubenbacher, Reinhard; Jarrah, Abdul Salam ABSTRACT Feedback loops play an important role in determining the dynamics of biological networks. To study the role of negative feedback loops, this article introduces the notion of distance-to- positive-feedback which, in essence, captures the number of independent negative feedback loops in the network, a property inherent in the network topology. Through a computational study using Boolean networks, it is shown that distance-to-positive- feedback has a strong influence on network dynamics and correlates very well with the number and length of limit cycles in the phase space of the network. To be precise, it is shown that, as the number of independent negative feedback loops increases, the number (length) of limit cycles tends to decrease (increase). These conclusions are consistent with the fact that certain natural biological networks exhibit generally regular behavior and have fewer negative feedback loops ...

Gankyrin has an antioxidative role through the feedback regulation of Nrf2 in hepatocellular carcinoma | JEMGankyrin has an antioxidative role through the feedback regulation of Nrf2 in hepatocellular carcinoma | JEM
In this study, we demonstrated that there is a positive feedback regulation between gankyrin and Nrf2, which amplifies the antioxidant capability of HCC cells. Under oxidative stress, increased Nrf2 activity promotes the transcription of gankyrin and up-regulates gankyrin expression. Excess gankyrin competitively interrupted the association between Nrf2 and Keap1 and subsequently stabilized Nrf2 protein. This positive feedback regulation helps combat excessive intracellular ROS, which reduces oxidative stress-induced cell death, maintains mitochondrial stability, and further contributes to the tumorigenesis of HCC. This feedback regulation is similar to the correlation between p62/SQSTM1 and Nrf2, as Nrf2 regulates the expression of p62/SQSTM1 through ARE, and in turn p62/SQSTM1 binds to Keap1 and prevents Nrf2 degradation (Jain et al., 2010). Similar to the p62/SQSTM1 protein, the human gankyrin protein contains an ELKE motif between aa 21-24 and an ENKE motif between aa 201-204, which serves ...

The data described above demonstrate a local PDE feedback regulation in cardiac myocytes whereby β1AR signals activate PDE4B3 via PKA-mediated phosphorylation. PKA-activated PDE4B, in turn, reduces the local steady-state cAMP concentration in a confined subsarcolemmal domain. The functional consequences of interrupting this feedback include increased PKA-mediated phosphorylation of Cav1.2 and RyR2, which is necessary for fine-tuning of ECC, a finding consistent with the cardiac phenotype of PDE4BKO mice (Leroy et al., 2011). Functional data on intracellular Ca2+ levels and contraction rate confirm the altered cAMP/PKA signaling in PDE4BKO myocytes. These conclusions are based on measurements of βAR-induced cAMP accumulation at the plasma membrane of PDE4BKO myocytes, the effects of acute PDE4B-selective inhibition in wild-type myocytes, the β1AR-dependent activation of PDE4B and the altered PKA-mediated phosphorylation of some, but not all substrates involved in Ca2+ homeostasis and ...

N2 - A novel thesis is that healthy aging of neuroendocrine axes is marked by disruption of orderly patterns of hormone release (1). This can be quantified by a recently validated approximate entropy statistic applied to 24-hour hormone profiles, e.g., luteinizing hormone (LH), and growth hormone (GH). Moreover, more subtle disturbances of feedback control are indicated by decreased conditional regularity or synchrony (higher cross-approximate entropy) within coupled axes, such as ACTH-cortisol, LH-testosterone, etc. Such alterations can precede any changes in mean serum hormone concentrations, thus highlighting an impact of age on the feedback control mechanisms that coordinate the flow of signaling information within a neuroendocrine axis or network..

Revitalising audit and feedback to improve patient care | The BMJRevitalising audit and feedback to improve patient care | The BMJ
The audit and feedback process comprises one or more cycles of establishing best practice criteria, measuring current practice, feeding back findings, implementing changes, and further monitoring. This chain is only as strong as its weakest link. Feedback effects can be weakened by information-intention gaps (feedback fails to convince recipients that change is necessary), intention-behaviour gaps (intentions are not translated into action), or behaviour-impact gaps (actions do not yield the desired effect on patient care).9 The success of national audit programmes depends on local arrangements that promote action as well as measurement.10. A synthesis of 65 qualitative evaluations proposed ways of designing audit programmes to better align with local capacity, identity, and culture and to promote greater changes in clinical behaviour.11 Healthcare organisations have finite capacity, so audit programmes should be designed so that they require less work, make best use of limited local resources, ...

The neurotransmitter 5-hydroxytryptamine (5-HT, serotonin) mediates important brain functions and contributes to the pathophysiology and successful drug treatment of many common psychiatric disorders, especially depression. It is established that a key mechanism involved in the control of 5-HT neurones is feedback inhibition by presynaptic 5-HT autoreceptors, which are located on 5-HT cell bodies and nerve terminals. However, recent experiments have discovered an unexpected complexity of 5-HT neurone control, specifically in the form of postsynaptic 5-HT feedback mechanisms. These mechanisms have the physiological effects of 5-HT autoreceptors but use additional 5-HT receptor subtypes and operate through neural inputs to 5-HT neurones.

This study uncovered a function of the dual specificity ERK MAP kinase phosphatase, MKP3, for the specification of mesenchymal progenitors in the somite sclerotome. We showed that Mkp3 was expressed in a twin-striped pattern, which closely matched the emergence of scleraxis transcripts along the anteroposterior somite edges (Fig. 1). This pattern suggested a link between the modulation of FGF signalling by MKP3 and scleraxis expression. We demonstrated that somitic expression of Mkp3 in the dorsal sclerotome was itself dependent on active ERK MAP kinase. This implied that FGF signalling in dorsal sclerotome cells is modulated by a negative feedback loop, which involves MKP3 and ERK MAP kinase. Indeed, we found that the levels of Mkp3 transcripts detected in response to FGF beads can cycle between extensive overexpression after a short exposure to complete loss of endogenous Mkp3 message after 24 hours (Fig. 3A-C; data not shown). We showed by western blot analysis that this dynamic response ...

Feedback amplification loop drives malignant growth in epithelial tissues | Proceedings of the National Academy of SciencesFeedback amplification loop drives malignant growth in epithelial tissues | Proceedings of the National Academy of Sciences
Interactions between cells bearing oncogenic mutations and the surrounding microenvironment, and cooperation between clonally distinct cell populations, can contribute to the growth and malignancy of epithelial tumors. The genetic techniques available in Drosophila have contributed to identify important roles of the TNF-α ligand Eiger and mitogenic molecules in mediating these interactions during the early steps of tumor formation. Here we unravel the existence of a tumor-intrinsic-and microenvironment-independent-self-reinforcement mechanism that drives tumor initiation and growth in an Eiger-independent manner. This mechanism relies on cell interactions between two functionally distinct cell populations, and we present evidence that these cell populations are not necessarily genetically different. Tumor-specific and cell-autonomous activation of the tumorigenic JNK stress-activated pathway drives the expression of secreted signaling molecules and growth factors to delaminating cells, which ...

This paper is concerned with the linear/nonlinear aeroelastic control of 2-D supersonic lifting surfaces. Its goal is to provide the feedback control mechanism enabling one to enlarge the flight envelope by increasing the flutter speed, and also to control the character, benign/catastrophic of the flutter instability boundary. Structural and aerodynamic nonlinearities are included in the aeroelastic governing equations, and linear and nonlinear feedback controls in both plunging and pitching are employed in conjunction with proportional velocity feedback controls. The attention of the paper is focused on multiple Hopf bifurcations. In particular, the jumping phenomenon found in our previous work will be further investigated to reveal the physical implications. It is found that such a jumping occurs when the system has multiple families of limit cycles bifurcating from a same set of parameter values with multiple solutions for frequencies. The case investigated in this paper is restricted to zero ...

Weve demonstrated the effectiveness of our protocol in a pilot study, and now were moving on to the next stage comprising a crossover clinical study with about 50 dialysis patients, says Chait, an expert on robust feedback control design. What we hope to show is that the demonstrated success with the pilot project translates to similar success with the larger study. This study is a much stronger test of the efficacy and safety of our protocol.. In dialysis patients the amount of EPO produced by the kidneys is inappropriately low for the level of anemia, and so they are treated with recombinant human EPO hormone in order to minimize the need for blood transfusions. Chait notes that current anemia management protocols for administering EPO are more or less one size fits all and fail to achieve the desired outcomes for many patients. That is where Chaits expertise comes in. By utilizing the principles of feedback control systems, his protocols enable medical personnel to personalize the EPO ...

The student feedback forms have, in essence, been a system of feedback that has been hit-and-miss with the students. On the one hand you have a system that tries to incorporate a flimsy notion of student rights whilst on the other hand you have a system that more often than not seems too distant from the student. The recent complaints directed at the feedback system, due to the delays in the publication of results, shows how certain shortcomings have limited the impact of the system at large..

Integrating Query Expansion and Conceptural Relevance Feedback for Web Information RetrievalIntegrating Query Expansion and Conceptural Relevance Feedback for Web Information Retrieval
When a query is commenced, the query is resolved as a similarity search by a couple of search engines (including AltaVista, Excite, etc.). The Web assistant then collects the top n (60 for the prototype) documents returned and groups them into clusters. What differs here from the Scatter/Gather by [4] is that the feedback of relevant clusters and the documents are not only gathered for clustering again but the query is modified for better formulating the information needed.. As we mentioned earlier, relevance feedback has long been suggested as a solution for query modification. Rocchio describes an elegant approach and shows how the optimal vector space query can be derived using vector addition and subtraction given the relevant and non-relevant documents [6]. The probabilistic model proposed by Robertson and Sparck Jones shows how to adjust the individual term weight based on the distribution of the terms in relevant and non-relevant document set [5].. Now, given the cluster or concept as ...

Thalamic activity is regulated by corticothalamic feedback from layers 5B and 6. The nature of these feedback systems differs, one difference being that whereas layer 5 provides driver input, the layer 6 input is thought to be modulatory. To selectively study the importance of the layer 6 corticothalamic (L6 CT) projection, a transgenic mouse line was used in which layer 6 cells projecting to posterior medial thalamus (POm) were targeted for expression of channelrhodopsin-2 and in vivo electrophysiology recordings were done in urethane-anaesthetized mice.

Online Tutor. Classroom Teacher. How Written Feedback Shifts | Another WordOnline Tutor. Classroom Teacher. How Written Feedback Shifts | Another Word
Thanks for this post, Matthew. This got me thinking a lot. For me, the difference between a tutoring session and a course is like that of a short story and a novel. In the session, I am making sure every moment and move matters. I feel the need to understand the assignment and writer as quickly as possible, make strategic choices about what to cover and how deeply, and get straight to the point. I am much more direct. I also cling to the prompt much more because I dont know if the instructor/ professor likes surprises and also because as an outside reader I feel thats one of my uses- I can usually see when something is going off track or not following directions. As a teacher, I think I spend a lot of time getting to know students and building a relationship with them. I comment mostly on ideas and logics that one might see as big picture concerns. And I deliberately write assignments to be open ended so that I am surprised. As I tutor I want the assignment and the prompt to match, in other ...

Additionally, for the majority of phosphorylation sites identified on the CD3γδζ subunits, we observed a gradual decrease in Zap-70 null/reconstituted SILAC ratios at early time points, followed by a gradual increase in Zap-70 null/reconstituted SILAC ratios at later time points (Fig. 7E2). These trends are consistent with the hypothesis of competing positive and negative feedback loops functioning at different stages of stimulation. At early time points, positive feedback mechanisms could be regulating these sites, leading to a gradual decrease in Zap-70 null/reconstituted SILAC ratios. At later time points, negative feedback mechanisms could be regulating these same sites, leading to an increase in Zap-70 null/reconstituted SILAC ratios when Zap-70 is removed (Fig. 7E1). It has previously been shown that Erk positive and SHP-1 negative feedback pathways can compete to either activate or inhibit Lck function to allow for T cells to discriminate between self and foreign ligands (47)..

post by melatoninpost by melatonin
As I said, I agree (for arguments sake) that the positive feedback loop is essential for switching the climate-systems between cold and warm states that are relative stable (i.e. ice-ages and interglacials). However, the positive feedback loop predominates only during the transition between states. Within each relatively stable state negative feedback must predominate or else stability would not be maintained. And today we find ourselves in just such a stable, negative feedback-dominated state in which climatic stability and equilibrium are maintained dynamically by the systems intrinsic negative feedback mechanism. In this state any global warming that occurs will be arrested automatically by the dominant negative feedback mechanism so that the default equilibrium temperature of the system is maintained within relatively narrow bounds. I think this by itself explains why no-one can find the tropospheric hotspot, regardless of any problems over our techniques of scientific measurement and the ...

Isolation of timeless by per protein-interaction - defective interaction between timeless protein and long-period mutant per(l)Isolation of timeless by per protein-interaction - defective interaction between timeless protein and long-period mutant per(l)
The period (per) gene likely encodes a component of the Drosophila circadian clock. Circadian oscillations in the abundance of per messenger RNA and per protein (PER) are thought to arise from negative feedback control of per gene transcription by PER. A recently identified second clock locus, timeless (tim), apparently regulates entry of PER into the nucleus. Reported here are the cloning of complementary DNAs derived from the tim gene in a two-hybrid screen for PER-interacting proteins and the demonstration of a physical interaction between the tim protein (TIM) and PER in vitro. A restricted segment of TIM binds directly to a part of the PER dimerization domain PAS. PERL, a mutation that causes a temperature-sensitive lengthening of circadian period and a temperature-sensitive delay in PER nuclear entry, exhibits a temperature-sensitive defect in binding to TIM. These results suggest that the interaction between TIM and PER determines the timing of PER nuclear entry and therefore the duration ...

Cahier G-2012-95 : GERADCahier G-2012-95 : GERAD
A previous article on the integrative modelling of Parkinsons disease (PD) described a mathematical model with properties that suggested that PD pathogenesis is associated with a feedback-induced biochemical bistability. In this article we show that the dynamics of the mathematical model can be extracted and distilled into an equivalent 2-state feedback motif whose stability properties are controlled by multi-factorial combinations of risk factors and genetic mutations associated with PD. Based on this finding, we propose a principle for PD pathogenesis in the form of the switch-like transition of a bistable feedback process from healthy homeostatic levels of reactive oxygen species and the protein α-synuclein, to an alternative disease state in which concentrations of both molecules are stable at the damagingly high levels associated with PD. The bistability is analysed using the rate curves and steady-state response characteristics of the feedback motif. In particular, we show how a ...

Frontiers | Haptic Feedback for Microrobotics Applications: A Review | Robotics and AIFrontiers | Haptic Feedback for Microrobotics Applications: A Review | Robotics and AI
Microrobotics systems are showing promising results in several applications and scenarios, such as targeted drug delivery and screening, biopsy, environmental control, surgery, and assembly. While most of the systems presented in the literature consider autonomous techniques, there is a growing interest in human-in-the-loop approaches. For reasons of responsibility, safety, and public acceptance, it is in fact beneficial to provide a human with intuitive and effective means for directly controlling these microrobotic systems.In this respect, haptic feedback is widely believed to be a valuable tool in human-in-the-loop teleoperation systems. This article presents a review of the literature on haptic feedback systems for microrobotics, categorizing it according to the type of haptic technology employed. In particular, we considered both tethered and untethered systems, including applications of micropositioning, microassembly, minimally invasive surgery, delivery of objects, micromanipulation, and
