<P>The genus Croceibacter of the family Flavobacteriaceae represents a ubiquitous component of marine bacterioplankton, and is known to be involved in the interaction with phytoplankton. Here, we report the isolation and genome sequencing of a lytic siphovirus P2559Y that infects Croceibacter atlanticus HTCC2559, the type strain of the genus Croceibacter. The complete genome of P2559Y was 43,153 bp in length, with a GC content of 38.9%. Functional annotation of 51 genes predicted in the genome showed that the P2559Y genome had a modular architecture. Comparison to the genome of P2559S, another phage that infects the same host strain, revealed an interesting feature in the genetic diversity of phages infecting the genus Croceibacter. The two phage genomes had a synteny in the structure module and shared many structural genes, while little similarity was found in the DNA replication/metabolism module. (C) 2016 Elsevier B.V.

Field-dependent Charge Transfer Mechanism in InP MIS Capacitors
Kang, I.,Lim, H. 慶熙大學校 1996 論文集 Vol.25 No.-
일정한 정전 용량 방법을 써서 InP MIS 축전기의 전하전달성을 연구하였다. 문전압변화를 전장의 세기와 전압인가 시간의 함수로 나타내기 위한 간단한 모델을 제안한다. 단순화하기 위하여 부도체내의 전하덧은 공간과 에너지에 대하여 균일한 분포를 갖는 것으로 가정한다. 두 종류의 시료들을 제작하였는데 한가지는 PECVD방법에 의해 성장된 질화규소 부도체막이고 다른 것은 전자속 방법에 의해 InP기판에 증착성장시킨 이산화규소 부도체막이다. 제안된 모델은 SiO_2/InP MIS 축전기에서의 문전압변화의 시간에 대한 의존성을 성공적으로 설명해준다. 그러나 SiN_x/InP MIS 축전기에 대해서는 이 모델은 완전하게 적절하지는 않다. 사용된 SiO_2와 SiN_x의 전하덧 에너지 분포범위는 각각 13 meV와 60 meV임이 발견된다.

Most tire properties are closely related to the pattern deformation. In order to explore the relationship between tire performance and defined deformation parameters in the contact area between the pneumatic tire and road surface, ten types of 205/55R16 passenger car radial (PCR) tires were selected as the research objects. Using VIC-3D non-contact strain measurement system and by subdividing the contact area, the pattern deformation in contact area under vertical load was tested, and the relevant deformation parameters of the contact area were extracted. Correlation analysis was used to establish the relationship between the identified deformation parameters and tire performance indicators. Then an evaluation method of tire performance based on the deformation parameters was proposed, as well as clarification of the contradictory mechanism between tire noise, rolling resistance and dry grip performance. While the results indicate tire noise having a significant negative correlation with radial deformation in the contact area, rolling resistance coefficient gave a significant positive correlation with its equivalent strain in the XY plane of the contact area, and dry braking distance positively correlates with tensile strain in the Y direction of contact area and negatively correlates with tensile strain in the X direction of the contact area.
