The simulator used to produce the images in the Siggraph 95 paper “Cellular Texture Generation” [5] was not originally designed as a Computer Graphics particlesystem simulator, although there are many similarities. It is instead a simulator designed for studying pattern formation in early biological development. Because it is intended for studying the patterns arising from the interactions of c...

Approximately 350,000 individuals in the United States rely on maintenance hemodialysis treatment because of end-stage renal disease. Despite improvements in dialysis technology, the mortality rate for patients treated with maintenance dialysis is still exceptionally high, with a 5-year survival rate of only 35%. Many patients succumb to conditions resulting at least in part from the chronic in...

BACKGROUND AND PURPOSE Hemodialysis patients are at high risk for ischemic stroke, and previous studies have noted a high rate of cardioembolism in this population. The aim of this study was to determine ischemic stroke causes among hemodialysis patients and elucidate specific cardioembolic stroke mechanisms. METHODS This study is a retrospective cross-sectional study of hemodialysis patients...

The purpose of this presentation is to describe the highlights of a research program designed to investigate the feasibility of creating a motion base driving simulator in a Cave Automatic Virtual Environment (CAVE). The goal of the project was to create the most effective simulator possible using a compact, portable motion system. In addition to reviews of state-of-the-art simulation technolog...

The authors present an approach for implementing a system for the assessment of medical competences using a haptic simulation device. Based on Competence based Knowledge Space Theory (CbKST), information on the learners’ competences is gathered from different sources (test questions, data from the simulator, and supervising experts’ assessments). The envisaged architecture consists of three cor...

This paper presents key technologies and system integration issues of the KAIST interactive bicycle simulator. The rider on the bicycle feels the motion and has the visual experience as if he/she is riding in the campus of the Korea Advanced Institute of Science and Technology. The simulator consists of a bicycle, a Stewart platform, a Magneto-Rheological handle and a pedal resistance system to...

OBJECTIVE Hemodialysis patients may have psychological distress and reduced quality of life (QoL) related to chronic physical health problems. Genetic polymorphisms associated with reduced QoL in hemodialysis patients. The aim of this study was to investigate the relationship between genetic polymorphisms and variation in health-related QoL in Korean hemodialysis patients. METHODS The 36-item...

This paper presents a software system that allows for multiple virtual machines connected by a network simulator to be utilized as an integrated network testbed. The system is built upon popular network simulator ns-3 and is capable of synchronizing user-supplied commands across different virtual machine instances. Performance evaluations are given to estimate limits of applicability of the sys...

BACKGROUND Although patients treated with maintenance hemodialysis are at an increased risk of colorectal cancer compared with the general population, national practices for colorectal cancer screening have not been reported in this population. We assessed the performance of colorectal cancer screening in the US end-stage renal disease program in comparison with the US Medicare population. ME...
