Abstract As reported previously, a porous composite of uncalcined hydroxyapatite (u‐HA) and poly‐ DL ‐lactide (PDLLA) showed excellent osteoconductivity biodegradability as bone substitute in rabbit model. In this study, to investigate the usefulness scaffold loaded with cells, we estimated whether material osteogenesis on implantation extraosseous site. On loading syngeneic marrow cells into rat dorsal subcutaneous tissue, enchondral ossification was seen both at 3 weeks after implantation....
We investigated the biocompatibility, osteoconductivity, and biodegradability of a porous composite hydroxyapatite (HA) poly-DL-lactide (PDLLA) implanted into rabbit femoral condyles compared it with HA. Six weeks after implantation, HA/PDLLA was covered bone contacted directly. The amount newly formed in pores similar both materials during examined period. tended to increase over 26 weeks, but that HA did not show significant 12 weeks. By remodeling seen marrow tissue found HA/PDLLA....
Kinesin superfamily protein UNC-104, a member of the kinesin-3 family, transports synaptic vesicle precursors (SVPs). In this study, number active UNC-104 molecules hauling single SVP in axons worm Caenorhabditis elegans was counted by applying newly developed non-invasive force measurement technique. The distribution acting on transported spread out over several clusters, implying presence force-producing units (FPUs). We then compared FPUs wild-type worms with that arl-8 gene-deletion...
We have proposed a quench detection method that uses low-temperature superconducting detector (LTS QD) for rare-earth barium copper oxide (REBCO) coils at 4.2 K. Previous studies demonstrated the with LTS QD in layer-wound REBCO coil. In this study, performance of QDs insulated, no-insulation (NI), and metal-as-insulation (MI) pancake was experimentally compared. An experiment used Nb–Ti/Cu–Ni installed NI, MI before thermal runaway coil K 0–9 T. showed slower without turn-to-turn...
Abstract The proposed Motion Picture Response Time (MPRT) measurement is designed to represent and quantify the visual perception of moving images across an AM‐LCD screen. MPRT method takes into account three basic LCD panel characteristics: capacitive‐hold‐type brightness variations, level dependent transition times a liquid crystal response time. Further, figure affected by back light control video signal processing algorithms. incorporates synchronously test pattern evaluation edge changes.
We used a novel composite fibre-precipitation method to create bioactive and bioresorbable cellular cubic composites containing calcium phosphate (CaP) particles (unsintered uncalcined hydroxyapatite (u-HA), alpha-tricalcium phosphate, beta-tricalcium tetracalcium dicalcium dihydrate, anhydrate or octacalcium phosphate) in poly-D/L-lactide matrix. The CaP occupied greater than equal 70 wt% (greater 50 vol%) fractions within the composites. porosities of were 70% interconnective pores...
Abstract Pigment organelles known as melanosomes disperse or aggregate in a melanophore response to hormones. These movements are mediated by the microtubule motors kinesin-2 and cytoplasmic dynein. However, force generation mechanism of dynein, unlike that kinesin, is not well understood. In this study, address issue, we investigated dynein-mediated aggregation zebrafish melanophores. We applied fluctuation theorem non-equilibrium statistical mechanics estimate forces acting on during...
Quench detection for the high-temperature superconducting tape, especially rare-earth barium copper oxide (REBCO) is difficult due to small normal zone propagation velocity in it. To address this issue, we have proposed a novel quench detectable REBCO tape with low-temperature wire used as detector, "REBCO/LTS <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">d</sub> tape." In paper, numerically and experimentally demonstrated validity of...
Quench detection in a rare-earth barium copper oxide (REBCO) coil is difficult due to the slow normal zone propagation it. To address this issue, we have proposed quench method using low temperature superconducting (LTS) wire as detector. A demonstration experiment our previous research REBCO tape showed that detector was able detect before it burned out. Therefore, verify applicability of real magnet system, first numerically evaluated detectability Nb-Ti and Nb <sub...
Abstract— In matrix display devices, image quality is influenced by pixel‐structure noise (fixed‐pattern noise) originating from the pixel arrangement. The influence of this on resolution and color investigated for four types arrangements. Spatial Nyquist limits (SNLs) based reciprocal lattices are first applied to determine primary these devices. Then actual visual (VRLs), which obtained subjectively evaluating sinusoidal patterns displayed simulated displays, compared SNLs in order assess...

As detector, TV cameras optically coupled to image intensifier...
A quench detection method using a low-temperature superconducting detector (QD) has been proposed to protect rare-earth barium copper oxide (REBCO) coils at temperatures below 20 K in magnetic fields. In this study, we first conducted an experiment 4.2 0-9 T locally- degraded REBCO tape and Nb-Ti QDs (Nb-Ti/Cu, Nb-Ti/Cu-Ni). Quick before thermal runaway of the was demonstrated by Nb-Ti/Cu-Ni QD T, whereas Nb-Ti/Cu exhibited quick only 9 T. Furthermore, numerically evaluated time attached...
A middle-aged woman who had undergone autologous hematopoietic stem cell transplantation (HSCT) 1 month previously suffered severe epigastralgia and relapse of lymphoma. The was not relieved by chemotherapy. Thereafter, her pancreatic hepatic enzyme levels were markedly elevated disseminated varicella emerged. Despite acyclovir administration, general condition deteriorated rapidly she died. Serum zoster virus (VZV) DNA level shown to be a diagnosis VZV infection established postmortem. In...
Near-field coupling communication (NFCC) is a technology that uses the surface of human body as transmission path. To suppress radiation signal from body, NFCC devices use carrier frequency less than 10 MHz. Because has potential to disturb other
Apatite micropattern was fabricated by a combination of biomimetic process and transcription resist pattern. We optimized some fabrication conditions such as the height pattern, temperature, concentrations pH simulated body fluid(SBF). Consequently, we successfully obtained apatite widely homogeneously on substrate in short period.

Near-field coupling communication (NFCC) is a technology that treats the surface of human body as transmission path by using carrier frequency below 10 MHz. Because radiation signal to space suppressed in NFCC, humans wearing an NFCC transceiver (TRX) can exchange personal information through handshaking without having worry about leakage. To establish stable exchange, needs satisfy two requirements relating propagation loss difference between standing and postures S/N ratio posture. From...
