No full text<p>(A) No significant correlation overall between the arrhythmia index (AI) and the systolic diameter (SD) phenotypes in F<sub>2</sub> progeny is observed (R<sup>2</sup> = 0.001, F-test, p = 0.88). (B) Crossing scheme design between <i>yw</i> and WE70. (C, D) Distribution plots of AI and SD by genotype showing incomplete penetrance of elevated AI in WE70 and the dispersion of phenotypes in the F<sub>2</sub> with approximately one-quarter aberrant flies. (E, F) Mean of AI and SD among WE70, <i>yw</i>, F<sub>1</sub> and F<sub>2</sub>. The error bar is representing S.E.M. of each group. The significant differences in AI and SD between WE70, <i>yw</i>, and F2 are indicated (t-test, *p<0.05, **p<0.01, ***p<0.001).The F<sub>1</sub> phenotype is intermediate between <i>yw</i> and WE70 for both AI and SD, but generally closer to <i>yw</i>.</p

Minimal Detectable Change and Clinically Important Difference of the Wolf Motor Function Test in Stroke Patients
No full textDirect numerical simulation of turbulent Couette-Poiseuille flow with zero skin friction
No full textThe near-wall scaling of mean velocity U(y) is addressed for the case of zero skin friction on one wall of a fully turbulent channel flow. The present DNS results can be added to the evidence in support of the conjecture that U is proportional to √yw in the region just above the wall at which the mean shear dU/dy = 0
Energy-Efficient Multi-Polling Scheme for Wireless LANs
No full text[[abstract]]In the past few years, IEEE 802.11 wireless LANs (WLANs) has rapidly gained large popularity for broadband wireless access. With the growing of various applications, users are demanding features such as higher throughput white keeping respectable operation time for their devices. To provide higher system bandwidth utilization, multi-polling mechanisms are often employed to reduce protocol overhead. However, they require wireless stations (STAs) to spend much time in overhearing which tends to waste energy and reduce battery lifetime. In this paper, we propose an energy-efficient multi-polling mechanism which combines power management strategy with a low overhead Medium Access Control (MAC) protocol. The main idea is to put STAs into the Doze state and determine a suitable wake-up time schedule to statistically achieve desirable guarantee of bandwidth utilization. From both analysis and simulation results, we found that, compared with the original ordered-contention multi-polling scheme, our proposed mechanism saves up to 80% of energy for a network consisting of 20 polled STAs with 5% loss of system bandwidth utilization as tradeoff. The significant saving of energy is a consequence of alleviating the overhearing problem with well scheduled wake-up times for STAs.[[note]]SC
Combination Of Cfd And Csd Packages For Fluid-Structure Interaction
No full textIn this article the UDF script file in the Fluent software was rewritten as the "connecting file" for the Fluent and the ANSYS/ABAQUS in order that the joined file can be used to do aero-elastic computations. In this way the fluid field is computed by solving the Navier-Stokes equations and the structure movement is integrated by the dynamics directly. An analysis of the computed results shows that this coupled method designed for simulating aero-elastic systems is workable and can be used for the other fluid-structure interaction problems
