Neuronal activity in the monkey prefrontal cortex during a duration discrimination task with visual and auditory cues
Autor: Atsushi Chiba, Kazunori Morita, Ken-ichi Oshio, Masahiko Inase
Publikováno v: Scientific Reports, Vol 11, Iss 1, Pp 1-14 (2021)
Abstract To investigate neuronal processing involved in the integration of auditory and visual signals for time perception, we examined neuronal activity in prefrontal cortex (PFC) of macaque monkeys during a duration discrimination task with auditor

A DC Fault Ride-Through Control of Half-Bridge MMCs for the HVDC Grid with DC Circuit Breakers
Autor: Atsushi Chiba, Kenichiro Sano, Yushi Koyama, Kei Sekiguchi, Takahiro Ishiguro, Daichi Suzuki
Publikováno v: 2022 International Power Electronics Conference (IPEC-Himeji 2022- ECCE Asia).
Operation delay of DC circuit breakers causes a voltage sag of several milliseconds in high-voltage DC (HVDC) grids. The DC voltage sag can cause an overcurrent in the DC side of the modular multilevel converter (MMC), resulting in halting the MMC. T

Publikováno v: Radioprotection. 55:317-324
This study was designed to examine how teachers in Fukushima Prefecture have shaped radiation education and gained consensus on radiation-related issues since the Fukushima Daiichi nuclear power plant accident. We interviewed teachers and external ex

Unruptured cystic artery pseudoaneurysm accompanied by Mirizzi syndrome: a report of a case
Autor: Kazumasa Nakamura, Ryuji Sugiyama, Yusuke Saito, Satoshi Suzuki, Ryuji Sukegawa, Kenichiro Ozawa, Akio Takada, Atsushi Chiba, Shunsuke Nakajima, Masaki Taruishi
Publikováno v: Clinical Journal of Gastroenterology. 6:490-495
Pseudoaneurysm of the cystic artery is a rare complication of cholecystitis. 34 cases have been reported from 1976 to 2012, searched on MEDLINE and most of the cases have presented with gastrointestinal bleeding. We report the third case of an unrupt

Copper Plating on SUS 304 Plate from Acid Bath
Autor: Atsushi Chiba, Yasunori Doi
Publikováno v: Advanced Materials Research. :1008-1011
SUS 304 used. A passive film on surface was needed to remove with anodic electrolytic degreasing in 3.0 mol/dm3 H2SO4 at 298 K. Cu film was electroplated 20 mA/cm2 in 0.5 mol/dm3 CuSO4 and 2 mol /dm3 H2SO4. Current efficiency increased when plating c

Synthesis and properties of samaria-doped ceria electrolyte for IT-SOFCs by EDTA-citrate complexing method
Autor: Atsushi Chiba, Wen-Chang Wu, Jui-Ting Huang
Publikováno v: Journal of Power Sources. 195:5868-5874
An ultra-fine samaria-doped ceria (Ce0.8Sm0.2O1.9, SDC) electrolyte prepared by a non-ion selective EDTA-citric complexing method is developed herein for intermediate-temperature solid oxide fuel cells (IT-SOFCs). The rigid agglomerates due to organi

A prospective randomized controlled multicenter trial of duodenoscopes with 5° and 15° backward-oblique angle using wire-guided cannulation: effects on selective cannulation of the common bile duct in endoscopic retrograde cholangiopancreatography

Publikováno v: Journal of Gastroenterology. 44:1140-1146
Background. In duodenoscopy, during endoscopic retrograde cholangiopancreatography (ERCP), a backward-oblique angle duodenoscope (BOAD) is generally used. In Japan, 15° BOAD are mainly used, but in Western countries, 5° BOAD are mostly used. In bil

Temporal filtering by prefrontal neurons in duration discrimination
Autor: Ken-ichi Oshio, Masahiko Inase, Atsushi Chiba
Publikováno v: European Journal of Neuroscience. 28:2333-2343
Neural imaging studies have revealed that the prefrontal cortex (PFC) participates in time perception. However, actual functional roles remain unclear. We trained two monkeys to perform a duration-discrimination task, in which two visual cues were pr
