Ergoline derivative LEK-8829-induced turning behavior in rats with unilateral striatal ibotenic acid lesions: interaction with bromocriptine. (1/2795)

LEK-8829 [9,10-didehydro-N-methyl-(2-propynyl)-6-methyl-8- aminomethylergoline bimaleinate] is an antagonist of dopamine D2 receptors and serotonin (5-HT)2 and 5-HT1A receptors in intact animals and a D1 receptor agonist in dopamine-depleted animals. In the present study, we used rats with unilateral striatal lesions with ibotenic acid (IA) to investigate the dopamine receptor activities of LEK-8829 in a model with innervated dopamine receptors. The IA-lesioned rats circled ipsilaterally when challenged with apomorphine, the mixed agonist on D1/D2 receptors. LEK-8829 induced a dose-dependent contralateral turning that was blocked by D1 receptor antagonist SCH-23390. The treatment with D1 receptor agonist SKF-82958 induced ipsilateral turning, whereas the treatment with D2 receptor antagonist haloperidol induced contralateral posture. The combined treatment with SKF-82958 and haloperidol resulted in a weak contralateral turning, indicating the possible receptor mechanism of contralateral turning induced by LEK-8829. Bromocriptine induced a weak ipsilateral turning that was blocked by haloperidol. The ipsilateral turning induced by bromocriptine was significantly potentiated by the coadministration of a low dose but not by a high dose of LEK-8829. The potentiation of turning was blocked either by SCH-23390 or by haloperidol. The potentiation of ipsilateral turning suggests the costimulation of D2 and D1 receptors by bromocriptine and LEK-8829, respectively, whereas the lack of potentiation by the highest dose of LEK-8829 may be explained by the opposing activity of LEK-8829 and bromocriptine at D2 receptors. We propose that the D2 and 5HT2 receptor-blocking and D1 receptor-stimulating profile of LEK-8829 is promising for the treatment of negative symptoms of schizophrenia.  (+info)

3D angiography. Clinical interest. First applications in interventional neuroradiology. (2/2795)

3D angiography is a true technical revolution that allows improvement in the quality and safety of diagnostic and endovascular treatment procedures. 3D angiography images are obtained by reconstruction of a rotational angiography acquisition done on a C-arm (GE Medical Systems) spinning at 40 degrees per second. The carotid or vertebral selective injection of a total of 15 ml of non-ionic contrast media at 3 ml/sec over 5 seconds allows the selection of the "arterial phase". Four hundred sixty 3D angiographic studies were performed from December 1996 to September 1998 on 260 patients and have been analyzed in MIP (Maximum Intensity Projection) and SSD (Shaded Surface Display) views. The exploration of intracranial aneurysms is simplified and only requires, for each vascular axis, a biplane PA and Lateral run followed by a single rotational angiography run. The 3D angiography image is available on the workstation's screen (Advantage Workstation 3.1, GE Medical Systems) in less than 10 minutes after the acquisition of the rotational run. It therefore allows one to analyze, during the intervention, the aneurysm's angioarchitecture, in particular the neck, and select the best therapeutic technique. When endovascular treatment is the best indication, 3D angiography allows one to define the optimal angle of view and accurately select the microcoils dimensions. 3D angiography replaces the multiple oblique views that used to be required to analyze the complex aneurysms and therefore allows a reduction of the total contrast medium quantity, the patient X-ray dose and the length of the intervention time which is a safety factor. Also, in particular for complex cases, it brings additional elements complementing the results of standard 2D DSA and rotational angiograms. In the cervical vascular pathology, 3D angiography allows for a better assessment of the stenosis level and of dissection lesions. Our current research activities focus on the matching without stereotactic frame between 3D X-ray angiography and volumetric MR acquisition, which should allow us to improve the treatment of intracerebral arterio-venous malformations (AVMs).  (+info)

Recovery of the vestibulocolic reflex after aminoglycoside ototoxicity in domestic chickens. (3/2795)

Avian auditory and vestibular hair cells regenerate after damage by ototoxic drugs, but until recently there was little evidence that regenerated vestibular hair cells function normally. In an earlier study we showed that the vestibuloocular reflex (VOR) is eliminated with aminoglycoside antibiotic treatment and recovers as hair cells regenerate. The VOR, which stabilizes the eye in the head, is an open-loop system that is thought to depend largely on regularly firing afferents. Recovery of the VOR is highly correlated with the regeneration of type I hair cells. In contrast, the vestibulocolic reflex (VCR), which stabilizes the head in space, is a closed-loop, negative-feedback system that seems to depend more on irregularly firing afferent input and is thought to be subserved by different circuitry than the VOR. We examined whether this different reflex also of vestibular origin would show similar recovery after hair cell regeneration. Lesions of the vestibular hair cells of 10-day-old chicks were created by a 5-day course of streptomycin sulfate. One day after completion of streptomycin treatment there was no measurable VCR gain, and total hair cell density was approximately 35% of that in untreated, age-matched controls. At 2 wk postlesion there was significant recovery of the VCR; at this time two subjects showed VCR gains within the range of control chicks. At 3 wk postlesion all subjects showed VCR gains and phase shifts within the normal range. These data show that the VCR recovers before the VOR. Unlike VOR gain, recovering VCR gain correlates equally well with the density of regenerating type I and type II vestibular hair cells, except at high frequencies. Several factors other than hair cell regeneration, such as length of stereocilia, reafferentation of hair cells, and compensation involving central neural pathways, may be involved in behavioral recovery. Our data suggest that one or more of these factors differentially affect the recovery of these two vestibular reflexes.  (+info)

Projections and firing properties of down eye-movement neurons in the interstitial nucleus of Cajal in the cat. (4/2795)

To clarify the role of the interstitial nucleus of Cajal (INC) in the control of vertical eye movements, projections of burst-tonic and tonic neurons in and around the INC were studied. This paper describes neurons with downward ON directions. We examined, by antidromic activation, whether these down INC (d-INC) neurons contribute to two pathways: a commissural pathway to the contralateral (c-) INC and a descending pathway to the ipsilateral vestibular nucleus (i-VN). Stimulation of the two pathways showed that as many as 74% of neurons were activated antidromically from one of the pathways. Of 113 d-INC neurons tested, 44 were activated from the commissural pathway and 40 from the descending pathway. No neurons were activated from both pathways. We concluded that commissural and descending pathways from the INC originate from two separate groups of neurons. Tracking of antidromic microstimulation in the two nuclei revealed multiple low-threshold sites and varied latencies; this was interpreted as a sign of existence of axonal arborization. Neurons with commissural projections tended to be located more dorsally than those with descending projections. Neurons with descending projections had significantly greater eye-position sensitivity and smaller saccadic sensitivity than neurons with commissural projections. The two groups of INC neurons increased their firing rate in nose-up head rotations and responded best to the rotation in the plane of contralateral posterior/ipsilateral anterior canal pair. Neurons with commissural projections showed a larger phase lag of response to sinusoidal rotation (54.6 +/- 7.6 degrees ) than neurons with descending projections (45.0 +/- 5.5 degrees ). Most neurons with descending projections received disynaptic excitation from the contralateral vestibular nerve. Neurons with commissural projections rarely received such disynaptic input. We suggest that downward-position-vestibular (DPV) neurons in the VN and VN-projecting d-INC neurons form a loop, together with possible commissural loops linking the bilateral VNs and the bilateral INCs. By comparing the quantitative measures of d-INC neurons with those of DPV neurons, we further suggest that integration of head velocity signals proceeds from DPV neurons to d-INC neurons with descending projections and then to d-INC neurons with commissural projections, whereas saccadic velocity signals are processed in the reverse order.  (+info)

Modified Bankart procedure for recurrent anterior dislocation and subluxation of the shoulder in athletes. (5/2795)

Thirty-four athletes (34 shoulders) with recurrent anterior glenohumeral instability were treated with a modified Bankart procedure, using a T-shaped capsular incision in the anterior capsule. The inferior flap was advanced medially and/or superiorly and rigidly fixed at the point of the Bankart lesion by a small cancellous screw and a spike-washer. The superior flap was advanced inferiority and sutured over the inferior flap. Twenty-five athletes (median age: 22) were evaluated over a mean period of follow-up of 65 months. The clinical results were graded, according to Rowe, as 22 (88%) excellent, 3 (12%) good, and none as fair or poor. The mean postoperative range of movement was 92 degrees of external rotation in 90 degrees of abduction. Elevation and internal rotation was symmetrical with the opposite side. Twenty-four patients returned to active sport, 22 at their previous level. This modified Bankart procedure is an effective treatment for athletes with recurrent anterior glenohumeral instability.  (+info)

Transport of colloidal particles in lymphatics and vasculature after subcutaneous injection. (6/2795)

This study was designed to determine the transport of subcutaneously injected viral-size colloid particles into the lymph and the vascular system in the hind leg of the dog. Transport of two colloid particles, with average size approximately 1 and 0.41 microm, respectively, and with and without leg rotation, was tested. Leg rotation serves to enhance the lymph flow rates. The right femoral vein, lymph vessel, and left femoral artery were cannulated while the animal was under anesthesia, and samples were collected at regular intervals after subcutaneous injection of the particles at the right knee level. The number of particles in the samples were counted under fluorescence microscopy by using a hemocytometer. With and without leg rotation, both particle sets were rapidly taken up into the venous blood and into the lymph fluid. The number of particles carried away from the injection site within the first 5 min was <5% of the injected pool. Particles were also seen in arterial blood samples; this suggests reflow and a prolonged residence time in the blood. These results show that particles the size of viruses are rapidly taken up into the lymphatics and blood vessels after subcutaneous deposition.  (+info)

Hip moments during level walking, stair climbing, and exercise in individuals aged 55 years or older. (7/2795)

BACKGROUND AND PURPOSE: Low bone mass of the proximal femur is a risk factor for hip fractures. Exercise has been shown to reduce bone loss in older individuals; however, the exercises most likely to influence bone mass of the proximal femur have not been identified. Net moments of force at the hip provide an indication of the mechanical load on the proximal femur. The purpose of this study was to examine various exercises to determine which exercises result in the greatest magnitude and rate of change in moments of force at the hip in older individuals. SUBJECTS AND METHODS: Walking and exercise patterns were analyzed for 30 subjects (17 men, 13 women) who were 55 years of age or older (X = 65.4, SD = 6.02, range = 55-75) and who had no identified musculoskeletal or neurological impairment. Kinematic and kinetic data were obtained with an optoelectronic system and a force platform. Results. Of the exercises investigated, only ascending stairs generated peak moments higher than those obtained during level walking and only in the transverse plane. Most of the exercises generated moments and rate of change in moments with magnitudes similar to or lower than those obtained during gait. CONCLUSION AND DISCUSSION: Level walking and exercises that generated moments with magnitudes comparable to or higher than those obtained during gait could be combined in an exercise program designed to maintain or increase bone mass at the hip.  (+info)

Orientation-tuned spatial filters for texture-defined form. (8/2795)

Detection threshold for an orientation-texture-defined (OTD) test grating was elevated after adapting to an OTD grating of high orientation contrast. Threshold elevation was greatest for a test grating parallel to the adapting grating, and fell to zero for a test grating perpendicular to the adapting grating. We conclude that the human visual system contains an orientation-tuned neural mechanism sensitive to OTD form, and propose a model for this mechanism. We further propose that orientation discrimination for OTD bars and gratings is determined by the relative activity of these filters for OTD form.  (+info)

Rotational instability of the knee may persist after anterior cruciate ligament (ACL) reconstruction, which may be due to insufficiency of anterolateral stabilizing structures. However, no reliable diagnostic tool or physical examination test is available for identifying patients with anterolateral rotatory instability (ALRI). As shown in cadaveric studies, static internal rotation of the knee is increased in higher flexion angles of the knee after severing the anterolateral structures. This might also be the case in patients with an ACL-deficient knee and concomitant damage to the anterolateral structures. The objective of this study is to assess anterolateral rotatory instability of the knee during physical examination with a tibial internal rotation test. ACL-injured knees of 52 patients were examined by two examiners and side-to-side differences were compared. Both lower legs were internally rotated by applying manual internal rotation torque to both feet in prone position with the knees in 30°, 60

FUEL CELL SYSTEM AND METHOD OF CONTROLLING ROTATION SPEED OF COMPRESSOR - Even when the atmospheric pressure is lowered, a sufficient amount of oxidant gas is supplied to a fuel cell without causing any failure in a compressor. A control unit judges whether or not both the following conditions are satisfied: the accelerator opening degree detected by an accelerator opening degree sensor is equal to or larger than a predetermined opening degree; and the state where the atmospheric pressure detected by a pressure sensor is equal to or lower than a predetermined pressure value has been maintained for a predetermined time period or longer. If the judgment result is positive, the control unit changes the maximum rotation speed permitted in the compressor from a normal maximum rotation speed to an increased maximum rotation speed. The control unit then judges whether or not a predetermined time period has elapsed from when the maximum rotation speed was changed to the increased maximum rotation speed, ...

We investigated the perception of self-rotation using constant-velocity chair rotations. Subjects signalled self motion during three independent tasks (1) by pushing a button when rotation was first sensed, when velocity reached a peak, when velocity began to decrease, and when velocity reached zero, (2) by rotating a disc to match the perceived motion of the body, or (3) by changing the static position of the dial such that a bigger change in its position correlated with a larger perceived velocity. All three tasks gave a consistent quantitative measure of perceived angular velocity. We found a delay in the time at which peak velocity of self-rotation was perceived (2-5 s) relative to the beginning or to the end of chair rotation. In addition the decay of the perception of self-rotation was preceded by a sensed constant-velocity interval or plateau (9-14 s). This delay in the rise of self-motion perception, and the plateau for the maximum perceived velocity, contrasts with the rapid rise and ...

Minimizing retinal image slip during locomotion is essential to maintain visual acuity (Angelaki and Hess, 2005; Angelaki and Cullen, 2008). For optimal performance, however, it is necessary that the spatiotemporal profile of gaze-stabilizing eye movements matches the organization and dynamics of the particular locomotory modality used. Although locomotion of terrestrial tetrapods with flexible necks generally requires relatively complex 3D eye movements to stabilize retinal images, the undulatory tail-based swimming of most aquatic vertebrates, such as larval Xenopus (Hoff and Wassersug, 1986; Azizi et al., 2007), necessitates only relatively simple paired (conjugate) ocular movements to counteract head rotational movements that are mainly in the horizontal plane. Indeed, such an eye motion profile has been recently observed during swimming in Xenopus tadpoles (Lambert et al., 2009, 2012), consistent with alternate burst discharge elicited in bilateral synergistic pairs of MR and LR motor ...

The connector pin assembly releasably retains telescoped excavating support and wear members in their telescoped relationship. The connector pin assembly is removably received in aligned connector openings in the members. A body portion of the assembly blocks removal of the wear member from the support member, and a lock member portion of the assembly is rotatable relative to the body, toward and away from a locking orientation, to releasably lock the body within the connector openings. A resilient sleeve having non-circular interior and exterior surfaces with rounded corners is non-slippably disposed over a rotatable shaft of the lock member in order to slidingly and deformably engage a non-circular shaped interior cavity of the body that rotatably receives shaft and sleeve of the lock member. The sleeve yieldingly resists rotational movement of the lock member away from a locking orientation.

Visual and non-visual cues, both static and dynamic, affect perception of body orientation relative to gravity. Prior research has investigated the relative influence of static orientation and dynamic rotation vestibular signals (from the otoliths and canals, respectively) on perceived body roll. We used a cue-conflict paradigm to directly compare the influence of static orientation and dynamic rotation visual cues. Vestibular stimulation was provided by rolling the subject. Visual stimulation was provided by a stereo display attached to the rolling device. Subjects set a visible rod to earth-vertical after being rolled to the target angle. In static conditions, the visual scene appeared only when the target angle was reached. In dynamic conditions, a rotating scene was visible throughout. The speed of the visual rotation was varied relative to the speed of the body rotation. Four visual scenes were used: 1) dynamic room scene; 2) static room; 3) static cube; 4) dynamic random-dot cloud. ...

Time experts are not sure why this should be so, but they have some ideas. Thomas R. OBrian, who heads NISTs Time & Frequency Division, Boulder, Colo., says the speed of the Earths rotation in the long term has tended to slow, but not during the past five years. The reasons, OBrian suggests, include changes in the motion of the Earths core, the effects of ocean tides and weather, and changes in the shape of the Earths magnetic field. He says most scientists expect the Earths spin to continue to slow in the future. OBrian says: "The Earths rotation rate has been the primary clock for nearly all of human history. ...

In an electronically commutated motor (M), rotor position signals are generated by means of a galvanomagnetic rotor position sensor (40). A timer (CNT_HL) brings about an advanced commutation which occurs only once the motor has reached a specific rotation speed, and whose magnitude is a function of the rotation speed.

Different modalities have been used to describe the rotational motion of the ventricles of the heart and studies have indicated LV twist to be an additional integral component in LV function. So far, only amplitudes and timings of rotation have been reported, whereas no method is available to fully describe the rotation pattern of the ventricles. The object of the present application is to achieve a system that presents a novel way to quantify and visualize the ventricular rotation pattern of the heart. We present a novel method that assesses and describes the rotation pattern by calculating the rotation axis of the ventricle. Non- invasive image acquisition is required to collect rotation values from different positions of the myocardium. Thereafter, a kinematic model of a ventricle is constructed to determine the rotation planes at different levels of the heart. The motion of the rotation planes are visualized by plotting the normal vectors of the planes over time, i.e. the rotation axis of ...

Regulation of the direction of flagellar rotation is central to the mechanism of bacterial chemotaxis. The transitions between counterclockwise and clockwise rotation are controlled by a switch complex composed of three proteins (FliG, FliM, and FliN) and located at the base of the flagellar motor. The mechanism of function of the switch is unknown. Here we demonstrate that the diffusible clockwise-signal molecule, the CheY protein, binds to the switch, that the primary docking site is FliM, that the extent of CheY binding to FliM is dependent upon the phosphorylation level of CheY, and that it is unaffected by the other two switch proteins. This study provides a biochemical demonstration of binding of a signal molecule to the bacterial switch and demonstrates directly that phosphorylation regulates the activity of this molecule ...

I should add that your expression in #1 represents a standing wave CP (sum of two counter-propagating CP waves of opposite CP polarization) not propagating one. For a single propagating CP wave, the sin(kz) term is absent and the cos(ωt), cos(ωt-π/2) arguments are replaced with cos(ωt-kz-θ), cos(ωt-π/2-kz-θ) respectively, with θ determined by the given t=0 temporal phase conditions at z=0. That may represent a LCP wave (left circularly polarized) - counterclockwise rotation of field as viewed along propagation axis with wave receding. For a RCP wave, an extra phase angle of π is added to either one, but not both, of the above arguments for cos. Convention for handedness can vary, but I believe above is the more standard one ...

The four limb buds begin to develop in the fifth week of gestation with all four having a parallel axis. The great toes initially develop in a preaxial position, and with medial rotation are seated at the midline by week seven. Intrauterine molding continues, with variable positioning of the feet, internal rotation of the tibia, and external rotation of the hip. This can lead newborns to have common deformities related to these positions. The lower extremities continue to externally rotate in the postnatal period until around age 8-10 years when adult values are typically reached. On average, femoral anteversion will decrease about 25 degrees to a value of 15 degrees, with the tibia externally rotating 15 degrees (Staheli, 1985 ...
High-flow motors - SAE InternationalHigh-flow motors - SAE International
The MS05/MSE05 from Poclain Hydraulics benefits from a new valving, the design of which has been optimized to considerably reduce pressure drops (a 50% reduction in pressure drops has been recorded compared to the standard MS05/MSE05 model). It has also been fitted with a closed and more robust cover. The MS high-flow range can withstand the most heavy-duty of workloads and the most extreme environmental conditions. The motors can reach speeds that are 50% higher without any additional pressure drops. As such, they can ensure better machine productivity. As it is now available in symmetrical two-displacement, the MS05/MSE05 no longer has a preferred rotation direction and promotes a maximum speed whatever the machines direction of travel. This characteristic is particularly useful in rail/road applications. This option also means that only a single reference needs to be used for the left and right motors of a vehicle, and thus simplifies the chains of supply and assembly. ...

TUM - First ever direct measurement of the Earths rotationTUM - First ever direct measurement of the Earth's rotation
A group with researchers at the Technical University of Munich (TUM) are the first to plot changes in the Earths axis through laboratory measurements. To do this, they constructed the worlds most stable ring laser in an underground lab and used it to determine changes in the Earths rotation. Previously, scientists were only able to track shifts in the polar axis indirectly by monitoring fixed objects in space. Capturing the tilt of the Earths axis and its rotational velocity is crucial for precise positional information on Earth - and thus for the accurate functioning of modern navigation systems, for instance. The scientists work has been recognized an Exceptional Research Spotlight by the American Physical Society.
High dispersion spectroscopy of solar-type superflare stars. I. Temperature, surHigh dispersion spectroscopy of solar-type superflare stars. I. Temperature, sur
We conducted high-dispersion spectroscopic observations of 50 superflare stars with Subaru High Dispersion Spectrograph (HDS), and measured the stellar parameters of them. These 50 targets were selected from the solar-type (G-type main sequence) superflare stars that we had discovered from the Kepler photometric data. As a result of these spectroscopic observations, we found that more than half (34) of our 50 targets have no evidence of binary systems. We then estimated the effective temperature (Teff), surface gravity (log g), metallicity ([Fe/H]), and projected rotational velocity (vsin i) of these 34 superflare stars on the basis of our spectroscopic data. The accuracy of our estimations is higher than that of the Kepler Input Catalog (KIC) values, and the differences between our values and KIC values [(DeltaTeff)rms ˜ 219 K, (Deltalog g)rms ˜ 0.37 dex, and (Delta[Fe/H])rms ˜ 0.46 dex] are comparable to the large uncertainties and systematic differences of KIC values reported by the ...

We show how to implement stick boundary conditions for a spherical colloid in a solvent that is coarse-grained by the method of stochastic rotation dynamics. This allows us to measure colloidal rotational velocity auto-correlation functions by direct computer simulation. We find quantitative agreement with Enskog theory for short times and with hydrodynamic mode-coupling theory for longer times. For aqueous colloidal suspensions, the Enskog contribution to the rotational friction is larger than the hydrodynamic one when the colloidal radius drops below 35 nm.

The possibility of causing adverse changes in patients profile as a result of mandibular displacement still causes concern in indicating maxillary expansions [8]. Clockwise rotation of the mandible with an increase in lower facial height has been reported as a side effect of SARME [6, 9]. In fact, our study found a clockwise rotation of the mandible immediately after SARME. This movement was represented by an increase in the values of the FMA as well as downward and backward displacements of the menton.. However, according to our results, the mandibular rotation seems to be a transient movement as the values observed 6 months after SARME (T3) tended to return close to their initial values (T1). Altug-Atac et al. [6] and Gunbay et al. [9] reported clockwise rotation of the mandible after SARME whereas Parhiz et al. [4] and Iodice et al. [10] did not observe significant rotational movement of the mandible. Methodological differences among these studies and assessment in different time points ...

We experimentally generated superpositions of higher-order Bessel beams that possess no global orbital angular momentum (OAM), yet exhibit an angular rotation in their intensity profile as the field propagates. The digital holograms encoded on a spatial light modulator (SLM), used for generating such fields, consist of two annular rings of unequal radial wave-vectors where each ring is encoded with an azimuthal mode of equal order but opposite charge. We present experimentally measured angular rotation rates for some example superposition fields, which are shown to be in good agreement with that predicted theoretically. Introducing a second SLM and a Fourier transforming lens, we demonstrate a simple approach to perform an azimuthal decomposition of our generated optical fields. Bounding the match-filter to an annular ring, of varying radius, we are able to perform a scale-independent azimuthal decomposition of our initial field. From the measured weightings of the azimuthally decomposed modes ...

During systole, the left ventricle twists around its long axis. This aids in the ejection of blood from the ventricle. Therefore, rotation and torsion are important factors in cardiac mechanics. Typically, a healthy left ventricle will rotate counterclockwise in the apical region and clockwise in the basal region with a net angle of 13 to 27 degrees.. Observations in a cohort of 30 heart failure patients with left bundle branch block (LBBB) show an abnormal twisting motion. To better understand the underlying mechanisms of this abnormal rotation behaviour, an in-silico study on (bi)ventricular, patient specific models will be conducted. Hence, we first create patient specific ventricular geometries from MRI data and perform (electro-)mechanical simulations.. ...

Each of the fixation zones is made from a material suitable for enabling their deformation by thermal action (tepid memory) or mechanical action (superelasticity), to permit an introduction into the bone parts without pulpar approach, followed by a fixation in the bone parts, while avoiding any rotational movement, withstanding the tensile stresses, and maintaining a compressive force. At least one of the fixation zones has two tabs or fins and which are separable under the effect of the deformation.

The shape functions therefore become multi-dimensional embeddings in the physical domains on the respective finite elements, generally spanning the dimensions associated with multiple degrees of freedom. On the Lie algebra, which is, by its mathematical construction, a vector space, rotations can be represented as translations, and it is this aspect which makes this approach particularly interesting for finite-element calculations that involve the modelling of rotations. In established finite element methods, translations and rotations are assigned different degrees of freedom (d.o.f.). Often, the components of the interpolant between two or more nodes belonging to a given finite element are then constructed separately on the basis the individual degrees of freedom, thus eliminating the interplay between translations and rotations that can be observed in the physical reality. Well-known deficiencies of many of these formulations, such as lack of geometric invariance, path dependence and ...

Which skaters in the past, (before CoP era) turned clockwise?
1906.00480] Vorticity, kinetic energy, and suppressed gravitational wave production in strong first order phase transitions1906.00480] Vorticity, kinetic energy, and suppressed gravitational wave production in strong first order phase transitions
Abstract: We have performed the first 3-dimensional simulations of strong first-order thermal phase transitions in the early Universe. For deflagrations, we find that the rotational component of the fluid velocity increases as the transition strength is increased. For detonations, however, the rotational velocity component remains constant and small. We also find that the efficiency with which kinetic energy is transferred to the fluid falls below theoretical expectations as we increase the transition strength. The probable origin of the kinetic energy deficit is the formation of reheated droplets of the metastable phase during the collision, slowing the bubble walls. The rate of increase in the gravitational wave energy density for deflagrations in strong transitions is suppressed compared to that predicted in earlier work. This is largely accounted for by the reduction in kinetic energy. Current modelling therefore substantially overestimates the gravitational wave signal for strong ...

Kiln Alignment - Preventative Maintenance Strategy. - Thermal bendingKiln Alignment - Preventative Maintenance Strategy. - Thermal bending
The rotary kilns are design to work for a very long time. Because rotation speed is quite slow all components needs some time to get damage, but want to ensure long service life of rotary kiln most of all the user has to take care of proper geometry of components.. First and a very important parameter is a base slope. If it is not correct can wear taper shape of rollers and tires. Irregular surface shape cause incorrect axial kiln balance or at least make it difficult to control this movement. Also the component wear is higher compared to align position of rollers (skewing, inclination etc.). High force of kiln thrust can increase the damage process of other components for example thrust roller, tire side surface, base plates etc.. Keeping kiln align is a very powerful tool of maintenance. Parallel position of tires and rollers running surfaces causes the same equal contact and stress distribution. Anyway after years of operation the contact surfaces will change into tapered or concave surface ...

Streamlines for Laminar Flow Past a Rotating Solid Cylinder - Wolfram Demonstrations ProjectStreamlines for Laminar Flow Past a Rotating Solid Cylinder - Wolfram Demonstrations Project
This Demonstration shows streamlines of the flow of a uniform, incompressible liquid past a rotating solid cylinder. Streamlines are imaginary lines drawn to illustrate the motion of the liquid; they can be interpreted as trajectories of small, light particles moving with the flow. Depending on the rotation speed, there are one or two stagnation points, displayed as red dots, where the liquid has

TY - JOUR. T1 - Dynamical simulations of magnetically channelled line-driven stellar winds - II. the effects of field-aligned rotation. AU - Ud-Doula, Asif. AU - Owocki, Stanley P.. AU - Townsend, Richard H.D.. PY - 2008/3. Y1 - 2008/3. N2 - Building upon our previous magnetohydrodynamics (MHD) simulation study of magnetic channelling in radiatively driven stellar winds, we examine here the additional dynamical effects of stellar rotation in the (still) 2D axisymmetric case of an aligned dipole surface field. In addition to the magnetic confinement parameter η* introduced in Paper I, we characterize the stellar rotation in terms of a parameter W ≡ Vrot/V orb (the ratio of the equatorial surface rotation speed to orbital speed), examining specifically models with moderately strong rotation W = 0.25 and 0.5, and comparing these to analogous non-rotating cases. Defining the associated Alfvén radius RA ≈ η1/4 * R* and Kepler corotation radius R K ≈ W-2/3 R*, we find rotation effects are ...
Patent US5563808 - Pilger mill mandrel measuring device - Google PatentsPatent US5563808 - Pilger mill mandrel measuring device - Google Patents
A method and an apparatus for measuring a tapered cylindrical object, such as a mandrel. The apparatus employs a linear positioning table assembly with a slide mounting for a laser micrometer, an axial position stepper motor for moving the laser micrometer stepwise along the axial length of the mandrel, and an angular position stepper motor for stepwise rotation of the object. The laser micrometer measures a cross-sectional diameter of the mandrel at a plurality of angular positions of the mandrel for each one of a plurality of axial positions along the length of the mandrel. The measurements taken at a plurality of angular positions constitute a circumference profile at that axial position. The circumference profiles at a plurality of axial positions constitute the contour profile of the mandrel. The acquired data are compared to desired mandrel contour profile data.

Givens rotation - WikipediaGivens rotation - Wikipedia
The following table shows the three Givens rotations equivalent to the different Euler angles conventions using extrinsic composition (composition of rotations about the basis axes) of active rotations and the right-handed rule for the positive sign of the angles. The notation has been simplified in such a way that c1 means cos θ1 and s2 means sin θ2). The subindexes of the angles are the order in which they are applied using extrinsic composition (1 for intrinsic rotation, 2 for nutation, 3 for precession) As rotations are applied just in the opposite order of the Euler angles table of rotations, this table is the same but swapping indexes 1 and 3 in the angles associated with the corresponding entry. An entry like zxy means to apply first the y rotation, then x, and finally z, in the basis axes. All the compositions assume the right hand convention for the matrices that are multiplied, yielding the following results. ...
Game Dev Algorithms / Mailing ListsGame Dev Algorithms / Mailing Lists
Dude, you do not have to transform the vertices! You only have to transform the translation component of the transform (not the rotation component)! When you build the matrix to send to the shader, just modify the translation component to be relative to the camera position. Also, I dont quite understand this conversation about high precision rotations. Rotations are always in object space, often represented as quaternions which are normalized rotation values and, with these, normal float precision is just fine. The only issue is the giant translation component which, with a minor joggle to your object-to-world transform can be easily corrected.

Precomputed Radiance Transfer (PRT) methods established for handling global illumination(GI) of objects from area lights in real-time and many techniques proposed for rotating the light using linear algebra rotation matrices.Rotating area lights efficiently is crucial part for Computer Graphics since is one of the main components of real-time rendering. Matrices commonly used for handling such rotations are not quite efficient and require high memory consumption;as a result the need for proposing new more efficient rotation algorithms has been established.In this work,we employ the CGA as the mathematical background for "GI in real-time"under distant IBL illumination,for diffuse surfaces with self-shadowing by efficiently rotating the environment light using CGA entities. Our work, is based on Spherical Harmonics (SH) which are used for approximating natural,area-light illumination as irradiance maps.Our main novelty, is that we extend the PRT algorithm by representing SH for the first time with ...
symmetry - Point group from mono to bulk MoS2 - Chemistry Stack Exchangesymmetry - Point group from mono to bulk MoS2 - Chemistry Stack Exchange
This is not a proper answer but can give you a clue. I arrived here looking for the same answer.. I didnt arrive to find the C6 rotation axis in bulk 2H-MoS2. On the other hand, if you look for the symmetry operations of the space group of 2H-MoS2 (P63/mmc, No. 194, D46h):. http://img.chem.ucl.ac.uk/sgp/large/194az1.htm. You can see that there are not any C6 rotation axis for this space group. Nevertheless, there are 6-fold screw axes (http://img.chem.ucl.ac.uk/sgp/misc/sixscrew.htm) and 6-fold inversion axes (http://img.chem.ucl.ac.uk/sgp/misc/barsix.htm).. You are right that the point group corresponding to this space group is D6h (https://en.wikipedia.org/wiki/Space_group#Table_of_space_groups_in_3_dimensions). And according to character tables a D6h point group should have C6 (http://symmetry.jacobs-university.de/cgi-bin/group.cgi?group=606&option=4).. Both things are contradictory. My background is Chemistry, and I am used to group theory applied to molecules rather than crystals. My guess ...

  • I used a model of the elastic properties of the Earth along with the seismically determined source properties of the earthquake to compute the change in the distribution of the Earth's mass caused by the earthquake, and hence its effect on the Earth's rotation, including the change in the length of the day and in the Earth's wobble," Gross told Explainer in an e-mail. (slate.com)
  • The solar day is gradually getting longer because Earth's rotation is slowing down ever so slightly," says Daniel MacMillan of NASA's Goddard Space Flight Center. (universetoday.com)

  • This is directly analogous to the 2D case of rotation about a point. (siggraph.org)
  • Now we can perform the first translation (of the rotation axis to pass through the origin) by using the matrix T (-x1, -y1, -z 1), i.e., move the point P1 to the origin. (siggraph.org)
  • A rotation about an external point, e.g. the Earth about the Sun, is called a revolution or orbital revolution, typically when it is produced by gravity. (wikipedia.org)
  • A rotation is simply a progressive radial orientation to a common point. (wikipedia.org)
  • If a rotation around a point or axis is followed by a second rotation around the same point/axis, a third rotation results. (wikipedia.org)
  • However, a rotation around a point or axis and a rotation around a different point/axis may result in something other than a rotation, e.g. a translation. (wikipedia.org)
