Particle focusing in planar geometries is essentially required order to develop cost-effective lab-on-a-chips, such as cell counting and point-of-care (POC) devices. In this study, a novel method for sheathless particle focusing, called "Elasto-Inertial Focusing", was demonstrated straight microchannel. The particles were notably aligned along the centerline of channel under pressure-driven flow without any additional external force or apparatus after addition an elasticity enhancer: PEO...
We present an efficient method for measuring cell stretching based on three-dimensional viscoelastic particle focusing. suspended cells in a biocompatible medium [poly(vinylpyrrolidone) solution phosphate-buffered saline]. The viscoelasticity significantly homogenized the trajectories of along centerline simple straight channel, which could not be achieved conventional Newtonian media. More than 95% red blood (RBCs) were successfully delivered to stagnation point cross-slot microchannel and...
Abstract Most microfluidic separation techniques rely largely on object size as a marker. The ability to separate micro-objects based their shape is crucial in various biomedical and chemical assays. Here, we develop an on-demand, label-free acoustofluidic method prolate ellipsoids from spherical microparticles traveling surface acoustic wave-induced radiation force torque. freely rotating non-spherical were aligned under the progressive field by counterrotating torque, major axis of was...
A simple pseudopotential scheme, which incorporates compositional disorder as an effective potential, is proposed for calculation of the band structure ternary compound semiconductors. It shown that present theory, free from any additional parameter, satisfactorily produces band-gap bowings compounds when lattice mismatch small.
In Brief Study Design. Prospective case-control study of multifidus muscle atrophy in 39 patients with unilateral lumbosacral radiculopathy and disc herniation 20 controls. Objective. To evaluate quantitatively the asymmetry muscles (herniated intervertebral disc; HIVD) by using magnetic resonance imaging (MRI). Summary Background Data. Histologic morphologic changes have been reported herniation, but there are few studies on radiculopathy. Methods. Bilateral L3–L4, L4–L5, L5–S1 levels were...
Metallic nanowires with excellent electrical conductivity and high aspect ratio are critical in the preparation of conductive polymer nanocomposites. In this work, highly polystyrene/silver nanowire (PS/AgNW) nanocomposites were prepared by latex blending, their rheological properties investigated. A yield long thin AgNWs was synthesized polyol method. incorporated monodisperse PS microspheres to produce a network structure providing pathways. An electrically obtained at an percolation...
We present a method for inferring the behavior styles of character controllers from small set examples. show that rich variations can be captured by determining appropriate reward function in reinforcement learning framework, and discovered applied to different environments scenarios. also introduce new algorithm recover unknown improves over original apprenticeship algorithm. representing style variety tasks, while still preserving key features given describe an adaptive process where...
Exercise training is a traditional method to maximize remaining function in patients with spinal cord injury (SCI), but the exact mechanism by which exercise promotes recovery after SCI has not been identified; whether truly beneficial effect on also remains unclear. Previously, we showed that epigenetic changes brain motor cortex occur and treatment leading modulation effectively functional SCI. We aimed determine how induces improvement rats subjected are engaged effects of exercise. A...
Kinematic analysis of the hyoid bone in a videofluorosopic swallowing study (VFSS) is important for assessing dysphagia. However, calibrating movement time-consuming, and its reliability shows wide variation. Computer-assisted has been studied to improve efficiency accuracy identification tracking, but performance limited. In this study, we aimed design robust network that can track automatically without human intervention. Using 69,389 frames from 197 VFSS files as data set, deep learning...
Poststroke depression (PSD) is a major psychiatric disorder that develops after stroke; however, whether PSD treatment improves cognitive and functional impairments not clearly understood. We reviewed data from 31 subjects with 34 age-matched controls without PSD; all underwent neurological, cognitive, assessments, including the National Institutes of Health Stroke Scale (NIHSS), Korean version Mini-Mental Status Examination (K-MMSE), computerized neurocognitive test (CNT), Modified Barthel...
We present methods for creating compact and efficient data-driven character controllers. Our first method identifies the essential motion data examples tailored a given task. It enables complex yet high-dimensional controllers, as well automatically generated connecting controllers that merge set of independent into much larger aggregate one without modifying existing ones. second iteratively refines basis functions to enable highly value functions. show our dramatically reduce computation...
