We present a new framework for simulating dynamic movements of complex hairstyles. The proposed framework, which treats hair as collection wisps, includes approaches to wisp and handling wisp-body collisions wisp-wisp interactions. For the simulation we introduce dynamics model, hybrid rigid multi-body, serial chain mass-spring models, formulate system using an implicit integration method. Consequently, simulator can impose collision/contact constraints systematically, allowing it handle...

Postburn pruritus is a common distressing sequela of burn wounds. Empirical antipruritic treatment often fails to have satisfactory outcome, as the mechanism it has not been fully elucidated. The aim this study was evaluate manifestation transient receptor potential vanilloid 3 (TRPV3), ankyrin 1 (TRPA1), and other related receptors in postburn pruritus. Sixty-five patients with (n = 40) or without 25) were investigated, including skin biopsies. Keratinocytes fibroblasts from biopsy samples...

Abstract This paper proposes a real‐time simulation technique for thin shells undergoing large deformation. Shells are objects such as leaves and papers that can be abstracted 2D structures. Development of satisfactory physical model runs in but produces visually convincing animation has been remaining challenge computer graphics. Rather than resorting to shell theory which involves the most complex formulations continuum mechanics, we adopt energy functions from discrete proposed by...

Particulate matter (PM2.5) is an environmental pollutant causing skin inflammatory diseases via epidermal barrier damage. However, the mechanism and related gene expression induced by PM2.5 remains unclear. Our aim was to determine effect of on human tissue ex vivo, elucidate T helper 17 cell-related cytokine function. We verified levels in PM2.5-treated using Quantseq (3' mRNA-Seq), Gene Ontology (GO) terms protein-protein interaction (PPI) networks were performed. The treatment...

The radiometric resolution of a motion-induced synthetic aperture radiometer (MISAR) is analytically obtained from the standard deviation baseline response, an observation scenario, and imaging method MISAR. intrinsic long integration time given by whole dwell on moving platforms improves compared with snapshot other nominal radiometers. In addition, it illustrated that MISAR holds tradeoff relationship between spatial resolutions.

Abstract Color quantization replaces the color of each pixel with closest representative color, and thus it makes resulting image partitioned into uniformly‐colored regions. As a consequence, continuous, detailed variations over corresponding regions in original are lost through quantization. In this paper, we present novel blind scheme for restoring such from color‐quantized input without priori knowledge method. Our identifies which pairs should have continuous image. Then, seamlessly...

Consequently, our ensures resulting inherently orthonormal, eliminating need intricate...

In this paper, we address the comment provided by Zheng and Palffy-Muhoray regarding our previous work on computing closest approach distance of two ellipsoids. Additionally, present experimental results that assess numerical error bounds in authors’ own implementation analytic solution for ellipses. We report very rare cases where distances ellipses are erroneously calculated as zero, which is impossible given radii not zero.
