Walking dysfunction occurs at a very high prevalence in stroke survivors. Human walking is phenomenon often taken for granted, but it mediated by complicated neural control mechanisms. The automatic process includes the brainstem descending pathways (RST and VST) intraspinal locomotor network. It known that leg muscles are organized into modules to serve subtasks body support, posture locomotion. Major kinematic mechanisms recognized minimize center of gravity (COG) displacement. Stroke...
This article introduces McPAT, an integrated power, area, and timing modeling framework that supports comprehensive design space exploration for multicore manycore processor configurations ranging from 90nm to 22nm beyond. At microarchitectural level, McPAT includes models the fundamental components of a complete chip multiprocessor, including in-order out-of-order cores, networks-on-chip, shared caches, system such as memory controllers Ethernet controllers. circuit detailed critical-path...
With their significant performance and energy advantages, emerging manycore processors have also brought new challenges to the architecture research community. Manycore are highly integrated complex system-on-chips with complicated core uncore subsystems.

Human visual attention in immersive virtual reality (VR) is key for many important applications, such as content design, gaze-contingent rendering, or gaze-based interaction. However, prior works typically focused on free-viewing conditions that have limited relevance practical applications. We first collect eye tracking data of 27 participants performing a search task four VR environments. Based this dataset, we provide comprehensive analysis the collected and reveal correlations between...
Abstract Enforcing fluid incompressibility is one of the time‐consuming aspects in SPH. In this paper, we present a local Poisson SPH (LPSPH) method to solve for particle based simulation. Considering pressure equation, first convert it into an integral form, and then apply discretization continuous equation discretized summation over all particles integration domain determined by geometry. To control approximation error, further integrate our solver predictive‐corrective framework avoid...
Prior foveated rendering methods often suffer from a limitation where the shading load escalates with increasing display resolution, leading to decreased efficiency, particularly when dealing retinal-level resolutions.

Understanding human visual attention in immersive virtual reality (VR) is crucial for many important applications, including gaze prediction, guidance, and gaze-contingent rendering. However, previous works on analysis typically only explored one specific VR task paid less to the differences between different tasks. Moreover, existing recognition methods focused 2D viewing conditions effectiveness of eye movements. We first collect head movements 30 participants performing four tasks, i.e.,...
Children diagnosed with Autism Spectrum Disorder (ASD) often exhibit motor disorders. Dance Movement Therapy (DMT) has shown great potential for improving the control ability of children ASD.

Robust light transport algorithms, particularly bidirectional path tracing (BDPT), face significant challenges when dealing with specular or highly glossy involved paths. BDPT constructs the full by connecting sub-paths traced individually from source and camera. However, it remains difficult to sample vertices on surfaces narrow-lobed BSDF, as poses severe constraints sampling in feasible direction. To address this issue, we propose a novel approach, called proxy , that enables efficient...
