地震波记录了下地幔中的各种不均一性,然而这些信号究竟反映的是热学还是化学上的特征尚无定论,因而地震学所包含的有关深部地球性质的信息还不太明确。对观察到的地震波速的精确解译需要对地球上可能存在的所有矿物的地震学性质有所了解。

Meiosis is a key event in gametogenesis that generates new combinations of genetic information and is required to reduce the chro- mosome content of the gametes. Meiotic chromosomes undergo a number of specialised events during prophase to allow meiotic recombination, homologous chromosome synapsis and reductional chromosome segregation to occur. In mammalian cells, DNA phys- ically associates with histones to form chromatin, which can be modified by methylation, phosphorylation, ubiquitination and acetylation to help regulate higher order chromatin structure, gene expression, and chromosome organisation. Recent studies have identified some of the enzymes responsible for generating chromatin modifications in meiotic mammalian cells, and shown that these chromatin modifying enzymes are required for key meiosis-specific events that occur during meiotic prophase. This review will discuss the role of chromatin modifications in meiotic recombination, homologous chromosome synapsis and regulation of meiotic gene expression in mammals.

BACKGROUND AND OBJECTIVE Previous studies have demonstrated an association between an increased risk of ischemic stroke and a genetic variant on chromosome *** underlying gene is thought to be a histone deacetylase 9(HDAC9).As sodium valproate(SVA)is an inhibitor of HDAC9,this study explored the association between exposure to SVA and the subsequent risk of recurrent stroke.

As the maritime sector embraces more technology to increase efficiency, lower carbon emissions, and adapt to meet modern challenges, cyber and cyber-physical safety become a more significant issue. However, unfortunately, much of past research view cyber-security issues in transportation as primarily information technology problems. This paper designs and uses a case study to illustrate how cyber-security and physical safety should be viewed together, cyber and physical (i.e. cyber-physical), when considering ship-to-ship and ship-to-shore interactions. while there is some scenario designing, this case study is built with real port data and ship systems to demonstrate a real-world cyber-attack on a ship. It shows plausible physical effects that affect the safety of those involved. This case study is also made realistic with a novel hybrid cyber range and hardware testbed environment, designed to examine the different effects a ship-based cyber-attack could potentially have on a port. This informs several solutions, technical and social, that could enhance cyber-physical safety in marine transportation.
