Efficient System for Transmitting a Few Words with Two-Channel Electrotactile Stimulation
verbal information electrotactile stimulation apparent movement
2009/6/9
We describe a novel artificial tactile system for transmitting a few words (verbal information) in which two-channel electrotactile stimulation capable of generating apparent movements is applied to t...
Development of an Internal Observation System for Biological Samples Using a Linear Micro-slicer
automation image processing internal constituents 3D visualization
2009/6/9
An image scanner (contact image sensor) was attached in the system to obtain 2-dimensional images from the sliced sample, not from the sliced section. By using an image scanner called a micro-slicer i...
Design Improvement of the Rotary Blood Pump by Computational Fluid Dynamics Analysis
artificial heart ventricular assist device axial flow blood pump computational fluid dynamics
2009/6/9
In this study, the pump performance derived from CFD analysis coincided well with the experimental results. From the results of the CFD analysis, the existence of reverse flows was found in the inflow...
Simulation of Soft Tissue Ablation for a VR Simulator
ablation FEM-based soft tissue model maximum shearing stress hypothesis
2009/6/9
In surgery, failure of ablation is fatal to patients, and the operation is difficult for residents to learn. Our study aims to provide a VR-based training environment for ablation. This paper presents...
Aging Effect of Web-safe Color Visibility on a White Background
aging effect visibility comparison white background paired comparison test contrast
2009/6/9
Elderly people have more opportunities to use information technology terminals because of the increasing dissemination of the Internet. Since visual functions are weakened with senescence, website vis...
Analysis of QT Prolongation Using Cardiac Action Potential Simulation
QT interval prolongation remodeling IKs current KCNE1 Luo-Rudy model
2009/6/9
In heart failure, QT interval and action potential duration (APD) is prolonged and IKs, a slow component of delayed rectifier potassium current, decreases. We have reported that the KCNE1 gene, coding...
Artificial Organ Made in vivo —Valve Leaflet of the Jellyfish Valve—
insert molding technique in vivo tissue jellyfish valve
2009/6/8
Artificial materials used for artificial organs have sufficient strength and durability. However, their biocompatibility has not been improved yet to the level of tissue-derived biomaterials. On the o...
Elasticity Imaging of Soft Tissue
elasticity imaging contact impedance method palpation equivalent mass
2009/6/8
Elasticity imaging of soft tissue with contact impedance method was performed to quantify medical palpation. Frequency changes of piezoelectric vibrator in contact with soft tissue depends on the elas...
Learning Processes and Pupillary Responses in Inverted Tracking Tasks
inverted tracking task pupil dilation sensorimotor transformation cognitive load automatization
2009/6/5
This finding suggests increasing automatization of the to-be-learned sensorimotor transformation. Pupil measures were not correlated with tracking error on individual trials, suggesting that the inver...
Automated Classification of Cerebral Arteries in MRA Images
Magnetic resonance angiography Maximum intensity projection (MIP) Cerebral arteries Image registration Computer-aided diagnosis
2009/6/5
The detection of unruptured aneurysms is a major task in magnetic resonance angiography (MRA). However, it is difficult for radiologists and/or neurosurgeons to detect small aneurysms on maximum inten...
Immunohistochemical detection of ENaCβ in the terminal Schwann cells associated with the periodontal Ruffini endings of the rat incisor
ENaCβ terminal Schwann cells periodontal Ruffini endings rat incisor
2009/5/8
Epithelial sodium channels (ENaCs) are a subfamily of ion channels within the degenerin/ENaC (DEG/ENaC) superfamily. Previous studies have shown the immunolocalization of ENaC in the neural elements...
Proposal of alternative mechanism responsible for the function of high-speed swimsuits
alternative mechanism high-speed swimsuits
2009/5/8
Since many top swimmers wearing Speedo LZR Racer swimsuits have broken world records, it is considered that the corset-like grip of suit supports the swimmers to maintain flexibility of movement and...
