Ventricular pressure-volume curve indices change with end-diastolic pressure. (1/3102)

Many indices have been proposed to describee the diastolic pressure-volume curve mathematically and permit quantification of the elastic properties of the myocardium itself in hopes that changes in the muscle caused by disease would b.e reflected in the diastolic pressure-volume curve. To date, none of the proposed indices has been shown convincingly to discriminate one group of patients from another. While this situation in part arises from the relatively large amount of noise introduced by the technical difficulties of measuring synchronous pressures and volumes during diastole in man, ther is a more fundamental difficulty. In practice, one can measure only a short segment of the entire pressure-volume curve, and the values of all diastolic pressure-volume curve parameters investigated change significantly when one uses different segments of the same pressure-volume curve to compute them. These results were derived from relatively noise-free pressure-volume curves obtained by filling nine excised dog left ventricles at a known rate and monitoring pressure-volume curve used to compute the parameter. Merely increasing measurement fidelity will not resolve this problem, because none of these parameters accurately characterizes the entire diastolic pressure-volume curbe from a segment like that which one can reasonably expect to obtain from humans.  (+info)

Evaluation of the force-frequency relationship as a descriptor of the inotropic state of canine left ventricular myocardium. (2/3102)

The short-term force-frequency characteristics of canine left ventricular myocardium were examined in both isolated and intact preparations by briefly pertubing the frequency of contraction with early extrasystoles. The maximum rate of rise of isometric tension (Fmas) of the isolated trabeculae carneae was potentiated by the introduction of extrasystoles. The ratio of Fmas of potentiated to control beats (force-frequency ratio) was not altered significantly by a change in muscle length. However, exposure of the trabeculae to isoproterenol (10(-7)M) significantly changed the force-frequency ratio obtained in response to a constant frequency perturbation. Similar experiments were performed on chronically instrumented conscious dogs. Left ventricular minor axis diameter was measured with implanted pulse-transit ultrasonic dimension transducers, and intracavitary pressure was measured with a high fidelity micromanometer. Atrial pacing was performed so that the end-diastolic diameters of the beats preceding and following the extrasystole could be made identical. Large increases in the maximum rate of rise of pressure (Pmas) were seen in the contraction after the extrasystole. The ratio of Pmax of the potentiated beat to that of the control beat was not changed by a 9% increase in the end-diastolic diameter, produced by saline infusion. Conversely, isoproterenol significantly altered this relationship in the same manner as in the isolated muscle. Thus, either in vitro or in situ, left ventricular myocardium exhibits large functional changes in response to brief perturbations in rate. The isoproterenol and length data indicate that the force-frequency ratio reflects frequency-dependent changes in the inotropic state, independent of changes in length.  (+info)

Subunit dissociation in fish hemoglobins. (3/3102)

The tetramer-dimer dissociation equilibria (K 4,2) of several fish hemoglobins have been examined by sedimentation velocity measurements with a scanner-computer system for the ultracentrifuge and by flash photolysis measurements using rapid kinetic methods. Samples studied in detail included hemoglobins from a marine teleost, Brevoortia tyrannus (common name, menhaden); a fresh water teleost, Cyprinus carpio, (common name, carp); and an elasmobranch Prionace glauca (common name, blue shark). For all three species in the CO form at pH 7, in 0.1 M phosphate buffer, sedimentation coefficients of 4.3 S (typical of tetrameric hemoglobin) are observed in the micromolar concentration range. In contrast, mammalian hemoglobins dissociate appreciably to dimers under these conditions. The inability to detect dissociation in three fish hemoglobins at the lowest concentrations examined indicates that K 4,2 must have a value of 10(-8) M or less. In flash photolysis experiments on very dilute solutions in long path length cells, two kinetic components were detected with their proportions varying as expected for an equilibrium between tetramers (the slower component) and dimers (the faster component); values of K 4,2 for the three fish hemoglobins in the range 10(-9) to 10(-8) M were calculated from these data. Thus, the values of K 4,2 for liganded forms of the fish hemoglobins appear to be midway between the value for liganded human hemoglobin (K 4,2 approximately 10(-6) M) and unliganded human hemoglobin (K 4,2 approximately 10(-12) M). This conclusion is supported by measurements on solutions containing guanidine hydrochloride to enhance the degree of dissociation. All three fish hemoglobins are appreciably dissociated at guanidine concentrations of about 0.8 M, which is roughly midway between the guanidine concentrations needed to cause comparable dissociation of liganded human hemoglobin (about 0.4 M) and unliganded human hemoglobin (about 1.6 M). Kinetic measurements on solutions containing guanidine hydrochloride indicated that there are changes in both the absolute rates and the proportions of the fast and slow components, which along with other factors complicated the analysis of the data in terms of dissociation constants. Measurements were also made in solutions containing urea to promote dissociation, but with this agent very high concentrations (about 6 M) were required to give measureable dissociation and the fish hemoglobins were unstable under these conditions, with appreciable loss of absorbance spectra in both the sedimentation and kinetic experiments.  (+info)

Using computerized video time lapse for quantifying cell death of X-irradiated rat embryo cells transfected with c-myc or c-Ha-ras. (4/3102)

Rat embryo fibroblasts that had been transfected with the c-myc or c-Ha-ras oncogene were X-irradiated, after which individual cells and their progeny were followed in multiple fields for 5-6 days by computerized video time lapse microscopy to quantify the lethal events that resulted in loss of clonogenic survival. The loss of clonogenic survival of X-irradiated (9.5 or 2.5 Gy) REC:myc cells was attributed almost entirely to the cells dying by apoptosis, with almost all of the apoptosis occurring after the progeny had divided from one to four times. In contrast, the loss of clonogenic survival of X-irradiated REC:ras cells was attributed to two processes. After 9.5 Gy, approximately approximately 60% of the nonclonogenic cells died by apoptosis (with a very small amount of necrosis), and the other 40% underwent a senescent-type process in which some of the cells and their progeny stopped dividing but remained as viable cells throughout 140 h of observation. Both processes usually occurred after the cells had divided and continued to occur in the cells' progeny for up to five divisions after irradiation. Furthermore, the duration of the apoptotic process was shorter for REC:myc cells (0.5-1 h) than for REC:ras cells (4-5 h). By using computerized video time lapse to follow individual cells, we were able to determine the mode of cell death. This cannot be determined by conventional clonogenic survival experiments. Also, only by following the individual cells and their progeny can the true amount of apoptosis be determined. The cumulative percentage of apoptosis scored in whole populations, without distinguishing between the progeny of individually irradiated cells, does not reflect the true amount of apoptosis that occurs in cells that undergo postmitotic apoptosis after irradiation. Scoring cell death in whole populations of cells gives erroneous results because both clonogenic and nonclonogenic cells are dividing as nonclonogenic cells are apoptosing or senescing over a period of many days. For example, after 9.5 Gy, which causes reproductive cell death in 99% of both types of cells, the cumulative percentage of the cells scored as dead in the whole population at 60- 80 h after irradiation, when the maximum amount of cumulative apoptosis occurred, was approximately 60% for REC:myc cells, compared with only approximately 40% for REC:ras cells.  (+info)

Model studies of chromatin structure based on X-ray diffraction data. (5/3102)

Model calculations are presented in order to interpret the X-ray diffraction diagrams given by chromatin gels. It is shown that by taking into account the hydration of chromatin subunits, the problem of calculating the interference function in concentrated gels is greatly simplified. In this way it is spossible to fully interpret the influence of concentration on the position and intensity of the various rings present in the X-ray diffraction patterns. The possibilities and limitations of models based on spherical symmetry are also discussed. It is concluded that each chromatin subunit most likely contains three turns of DNA in each 200 base pairs segment surrounding a central protein core. With the method presented here it is possible to test if other models of chromatin based on different kinds of evidence are compatible with the X-ray diffraction data.  (+info)

Automated collection of quality-of-life data: a comparison of paper and computer touch-screen questionnaires. (6/3102)

PURPOSE: To evaluate alternative automated methods of collecting data on quality of life (QOL) in cancer patients. After initial evaluation of a range of technologies, we compared computer touch-screen questionnaires with paper questionnaires scanned by optical reading systems in terms of patients' acceptance, data quality, and reliability. PATIENTS AND METHODS: In a randomized cross-over trial, 149 cancer patients completed the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30, version 2.0 (EORTC QLQ-C30), and the Hospital Anxiety and Depression Scale (HADS) on paper and on a touch screen. In a further test-retest study, 81 patients completed the electronic version of the questionnaires twice, with a time interval of 3 hours between questionnaires. RESULTS: Fifty-two percent of the patients preferred the touch screen to paper; 24% had no preference. The quality of the data collected with the touch-screen system was good, with no missed responses. At the group level, the differences between scores obtained with the two modes of administration of the instruments were small, suggesting equivalence for most of the QOL scales, with the possible exception of the emotional, fatigue, and nausea/vomiting scales and the appetite item, where patients tended to give more positive responses on the touch screen. At the individual patient level, the agreement was good, with a kappa coefficient from 0.57 to 0.77 and percent global agreement from 61% to 97%. The electronic questionnaire had good test-retest reliability, with correlation coefficients between the two administrations from 0.78 to 0.95, kappa coefficients of agreement from 0.55 to 0.90, and percent global agreement from 56% to 100%. CONCLUSION: Computer touch-screen QOL questionnaires were well accepted by cancer patients, with good data quality and reliability.  (+info)

Binding conformers searching method for ligands according to the structures of their receptors and its application to thrombin inhibitors. (7/3102)

AIM: To develop a method of finding binding conformers for ligands according to the three-dimensional structures of their receptors. METHODS: Combining the systematic search method of ligand with the molecular docking approach of ligand fitting into its receptor, we developed a binding conformer searching method for ligands. RESULTS: The binding conformers of phosphonopeptidyl thrombin inhibitors were recognized. The binding (interaction) energies between these inhibitors and thrombin were calculated with molecular mechanical method. CONCLUSION: Both of the total binding energies and steric binding energies have good correlations with the inhibitory activities of these thrombin inhibitors, demonstrating that our approach is reasonable. It can also be used to explain the inhibition mechanism of thrombin interacting with these inhibitors.  (+info)

Computer method for predicting the secondary structure of single-stranded RNA. (8/3102)

We present a computer method utilizing published values for base pairing energies to compute the most energetically favorable secondary structure of an RNA from its primary nucleotide sequence. After listing all possible double-helical regions, every pair of mutally incompatible regions (whose nucleotides overlap) is examined to determine whether parts of those two regions can be combined by branch migration to form a pair of compatible new subregions which together are more stable than either of the original regions separately. These subregions are added to the list of base pairing regions which will compete to form the best overall structure. Then, a 'hyperstructure matrix' is generated, containing the unique topological relationship between every pair of regions. We have shown that the best structure can be chosen directly from this matrix, without the necessity of creating and examing every possible secondary structure. We have included the results from our solution of the 5S rRNA of the cyanobacterium Anacystis nidulans as an example of our program's capabilities.  (+info)

Coarray Fortran (CAF), formerly known as F--, started as an extension of Fortran 95/2003 for parallel processing created by Robert Numrich and John Reid in the 1990s. The Fortran 2008 standard (ISO/IEC 1539-1:2010) now includes coarrays (spelled without hyphen), as decided at the May 2005 meeting of the ISO Fortran Committee; the syntax in the Fortran 2008 standard is slightly different from the original CAF proposal.. A CAF program is interpreted as if it were replicated a number of times and all copies were executed asynchronously. Each copy has its own set of data objects and is termed an image. The array syntax of Fortran is extended with additional trailing subscripts in square brackets to provide a concise representation of references to data that is spread across images.. The CAF extension has been available for a long time[clarification needed] and was implemented in some Fortran compilers such as those from Cray (since release 3.1). Since the inclusion of coarrays in the Fortran 2008 ...

A small computer system interface (SCSI) driver circuit having a programmable slew rate comprises N cascaded delay cells each including a data bit input, a delayed data bit output that communicates with the data bit input of an adjacent one of the N cascaded delay cells, and a delay time input that receives a programmable delay time value for setting a variable delay between receiving data at the data bit input and generating the delayed data bit output. N predrivers receive an output enable signal and a corresponding one of the N delayed data bit outputs and generate a predriver output signal based on the output enable and the corresponding one of the N delayed data bit outputs. N drivers have inputs that receive predriver output signals from corresponding ones of the N predrivers. An output port communicates with outputs of the N drivers.
SCSI (uttales skøssi) er en forkortelse for Small Computer System Interface og er en standard defineret av ANSI X3.131 i 1986. SCSI brukes på PC-er, men først og fremst servere for å koble til lagringsenheter, scannere mm. SCSI var standard i Apple Macintosh maskiner frem til 1999. SCSI-adapteret er ofte et tilleggskort (som regel PCI) som kan monteres inne i datamaskinen. Noen datamaskiner har et innebygget SCSI-grensesnitt. Standarden ble utviklet av Shugart Technology, som senere skiftet navn til Seagate. Det finnes mange varianter av SCSI-standarden ...
The objectives of this article are (i) to utilize computer methods in detection of stent struts imaged in vivo by optical coherence tomography (OCT) during percutaneous coronary interventions (PCI); (ii) to provide measurements for the assessment and monitoring of in-stent restenosis by OCT post PCI. Thirty-nine OCT cross-sections from seven pullbacks from seven patients presenting varying degrees of neointimal hyperplasia (NIH) are selected, and stent struts are detected. Stent and lumen boundaries are reconstructed and one experienced observer analyzed the strut detection, the lumen and stent area measurements, as well as the NIH thickness in comparison to manual tracing using the reviewing software provided by the OCT manufacturer (LightLab Imaging, MA, USA). Very good agreements were found between the computer methods and the expert evaluations for lumen cross-section area (mean difference = 0.11 ± 0.70 mm2; r2 = 0.98, P < 0.0001) and the stent cross-section area (mean difference = 0.10 ± ...

Notifications to computer users are provided via indicators such as lights. The indicators are controlled according to rules, to convey computer-related state information to users in a consistent manner. Locations of visible indicators are chosen to facilitate easy viewing. The rules dictate colors and/or illumination pattern components that together provide users with important computer-related information. For example, colors are assigned to types of information, and illumination patterns generally to behavior-related information. Colors may be combined in various illumination patterns. In one implementation, many or all of the visible indicators may be grouped together on a single control panel from rapid viewing. Alternatively, the visible indicators may be grouped by function or other logical arrangement, such as on the keyboard and/or frame of a monitor.

Mechanisms and techniques provide the system that allows a sending computer system to capture and store event information related to events that transpire on a sending computer system in event batches. The event information can include event functionality related to event object in the timestamp related to the event. Periodically, in response to the occurrence of the batch transfer condition, the sending computer system transmits an event batch monthly computer network for receipt by a receiving computer system. The event batch may be processed through a collaboration adapter on the networks while prior to being send to the receiving computer system. Upon receipt of an event batch at the receiving computer system, the receiving computer system can compute a lag time required to receive the event batch. The receiving computer system can then recreate events based on the event information in the event batches while compensating for network lag time incurred during transmission of the event batch between a

Downloadable! We review the empirical literature about the implications of the computerization of the labor market to see whether it can explain observed computer adoption patterns and (long-term) changes in the wage structure. Evidence from empirical micro studies turns out to be inconsistent with macro studies that are based on CES production functions. We propose a micro foundation for the CES production function that allows for changes in the underlying structure. We adapt the macro model by incorporating computer skills, complementary skills and fixed costs for computer technology usage suggested by the micro literature. It turns out that fixed costs for computer technology usage explain different patterns of computer adoption and diffusion between several types of workers and countries; it also provides very plausible patterns of the timing of wage inequality and developments over time.

In late 1972, a French team headed by François Gernelle within a small company, Réalisations & Etudes Electroniqes (R2E), developed and patented a computer based on a microprocessor - the Intel 8008 8-bit microprocessor. This Micral-N was marketed in early 1973 as a Micro-ordinateur or microcomputer, mainly for scientific and process-control applications. About a hundred Micral-N were installed in the next two years, followed by a new version based on the Intel 8080. Meanwhile, another French team developed the Alvan, a small computer for office automation which found clients in banks and other sectors. The first version was based on LSI chips with an Intel 8008 as peripheral controller (keyboard, monitor and printer), before adopting the Zilog Z80 as main processor.. In late 1972, a Sacramento State University team led by Bill Pentz built the Sac State 8008 computer,[15] able to handle thousands of patients medical records. The Sac State 8008 was designed with the Intel 8008. It had a full ...

0103]Like the reel 110, 160 or 170 according to the second, third and fourth embodiments, the reel 180 according to the fifth embodiment described above also produces the effect of preventing the lower and upper flanges 142 and 144 from being displaced or deformed toward the magnetic tape T, even when the hub 162 is deformed inward due to winding pressure of the magnetic tape T. That is, in the reel 180, there is no tendency that the lower flange 142 is deformed in compliance with the hub 162 being deformed, since the lower flange 142 is not secured to the hub 162. Further, the hub 162 is liable to be deformed inward at an upper end side due to the magnetic tape T being wound thereon since the hub 162 has a higher strength with respect to the magnetic tape T at a lower end side than at an upper end side. But because of the hub being structured such that little or no winding pressure acts on the smaller-diameter portion 162B, provided on the upper end portion having a lower strength, thus the ...

Petroleum reservoir engineering may be defined as that branch of applied science which strives to understand the mechanics affecting petroleum reservoirs and petroleum production, and to apply that understanding to the efficient operation of petroleum reservoirs. During recent years, this branch of engineering has experienced tremendous growth in both depth and scope. Increased demand by our society for energy, increasing difficulty in discovering major quantities of domestic petroleum, and greater governmental concern, both domestic and foreign, for maximizing utilization of national resources, have added to the natural impetus of scientific curiosity in this field. The development of digital computers has contributed greatly to advancing this branch of applied science because it provided a possible means for performing the enormous volume of calculations required to solve complex reservoir engineering problems. In this paper, we will concern ourselves with the application of models to oil ...
While it is widely recognized that comprehension monitoring is an important reading comprehension ability, effective methods for teaching readers to recognize and overcome various comprehension obstacles have not yet been conclusively identified. To determine if microcomputers could be used to teach students to overcome such obstacles, 41 fourth grade students were randomly assigned to groups in a Solomon four-group design. The four groups were (1) a control group that received no treatment and that did not complete the Real World Reading Test (RWRT) as a pretest; (2) a control group that received no treatment, but that did complete the RWRT; (3) an experimental group that did not complete the RWRT as a pretest; and (4) an experimental group that did. Students in all groups took the RWRT as a posttest, as well as the Gates-MacGinitie reading comprehension test as a pretest. The students in the experimental groups worked at microcomputers using materials especially designed to teach

With each passing day, we spend more time on computers and expect them to meet more complex needs. Computer hardware engineers have a leading role in the research on, and development of, advanced computer technology, and even influence how its used. Computer hardware engineers research, design, and test computer systems and components such as processors, circuit boards, memory, and storage media. In most cases, the goal of computer hardware engineers is to discover ways to make computers faster and more powerful. Some more specialized engineers design other devices that incorporate computers- like cars and medical equipment. Some work closely with software developers to design phones, tablets, and other devices. Computer hardware engineers need to be creative problem-solvers, and work well as a member of a team... using their powers of reason to find original solutions.

In the field of computer forensics, it often is difficult for the examiner to conclude who a particular computer user was. A computer forensics examination may identify significant evidence including metadata about what was found on a computer or other digital media and when it was placed there. However, it is a separate question about who accessed or placed the content on the computer. For example, in a household with multiple potential users of a computer, how certain can the examiner be about who accessed a particular file? Sometimes the user may be inferred by the content. For example, if the computer forensic examination confirms that an individual sent and reviewed an email account linked to the individual moments before and after a key event (such as downloading a file or drafting a particular document), it may be logical to infer that the same user was responsible for the key event. The Eighth Circuit recently considered a challenge to the admission of a computer forensic expert ...

One of the most efficient therapy for correcting minicomputer malfunction is that which opens up the channels between the minicomputers and restores communication, thus removing the adaptation information from their terminals and unblocking the system. This allows information to be processed in structure, chemistry or electromagnetic therapeutic files so the body can treat its causal imbalances rather than the effects of disease or injury.. The integrity of all the bodys computers is evaluated by looking for Phase I clarity - five sector group muscle test for Local Computer, leg length for Spinal Computer, arm length for Endocrine Computer, pinch test for Primary Computer (see CK Examination Phase I).. When the body is clear in Phase I, the minicomputers are communicating properly.

Programs. The defining feature of modern computers which distinguishes them from all other machines is that they can be programmed. That is to say that some type of instructions (the program) can be given to the computer, and it will process them. Modern computers based on the von Neumann architecture often have machine code in the form of an imperative programming language.. In practical terms, a computer program may be just a few instructions or extend to many millions of instructions, as do the programs for word processors and web browsers for example. A typical modern computer can execute billions of instructions per second (gigaflops) and rarely makes a mistake over many years of operation. Large computer programs consisting of several million instructions may take teams of programmers years to write, and due to the complexity of the task almost certainly contain errors. ...
Edward Lorenz was an early pioneer of the theory. His interest in chaos came about accidentally through his work on weather prediction in 1961.[13] Lorenz was using a simple digital computer, a Royal McBee LGP-30, to run his weather simulation. He wanted to see a sequence of data again, and to save time he started the simulation in the middle of its course. He did this by entering a printout of the data that corresponded to conditions in the middle of the original simulation. To his surprise, the weather the machine began to predict was completely different from the previous calculation. Lorenz tracked this down to the computer printout. The computer worked with 6-digit precision, but the printout rounded variables off to a 3-digit number, so a value like 0.506127 printed as 0.506. This difference is tiny, and the consensus at the time would have been that it should have no practical effect. However, Lorenz discovered that small changes in initial conditions produced large changes in long-term ...
