An ML 3.0 earthquake occurred in the Seoul metropolitan area(SMA),Korea,on 9 February *** unexpected shaking attracted much attention and raised concerns about the seismic hazards and risks in the SMA,where only a few minor earthquakes had been reported and which was regarded as an area safe from any earthquake *** SMA has a population of 25.6 million and is one of the largest metropolitan areas in the *** noticed a cluster of closely spaced earthquakes by carefully reviewing continuous seismic *** there are historic documents reporting instances of strong shaking and related damage,this is the first time that a clustered seismicity from the instrumental records has been *** focal mechanism

利用宽频带流动台站(YSBSN)记录的远震波形数据和远震接收函数方法,反演了黄海东、西两侧地壳上地幔的S波速度结构.结果表明,莫霍面深度在30～38 km之间变化,位于中方一侧的JNN台下方地壳厚度最大,可以归因于华北板块和扬子板块的碰撞;韩方一侧的地壳厚度自北向南逐渐变厚,但仍然难以厘定朝鲜半岛南部潜在碰撞带的位置,这些问题的解决需要更大范围的流动台站观测.由于部分台站位于巨厚的沉积层和多孔的火山岩之上,与浅部构造的相关性使得接收函数表现出较大振幅的混响,从而影响了来自深部结构的转换震相.

This study examined whether exposure to a firm＇s report of corporate social responsibility （CSR） activities affected attitudes toward the firm and increased behavioral intent to purchase products and services from it. Findings showed that increased knowledge of a company＇s CSR deeds fosters positive attitudes and favorable purchase intentions toward the company. Reports that compared the firm＇s CSR activities to the competitor＇s activities favorably affected consumers＇ attitudes and purchase intentions positively. On the other hand, self-promotional reports affected neither attitudes nor purchase intentions significantly.

A critical challenge hindering the practical application of lithium–oxygen batteries(LOBs)is the inevitable problems associated with liquid electrolytes,such as evaporation and safety *** study addresses these problems by proposing a modified polyrotaxane(mPR)-based solid polymer electrolyte(SPE)design that simultaneously mitigates solvent-related problems and improves ***-SPE exhibits high ion conductivity(2.8×10^(−3)S cm^(−1)at 25℃)through aligned ion conduction pathways and provides electrode protection ability through hydrophobic chain *** this mPR-SPE into solid-state LOBs resulted in stable potentials over 300 *** situ Raman spectroscopy reveals the presence of an LiO_(2)intermediate alongside Li_(2)O_(2)during oxygen *** situ X-ray diffraction confirm the ability of the SPE to hinder the permeation of oxygen and moisture,as demonstrated by the air permeability *** present study suggests that maintaining a low residual solvent while achieving high ionic conductivity is crucial for restricting the sub-reactions of solid-state LOBs.

To the Editor: Xanthogranulomatous cholecystitis(XGC) is an uncommon inflammatory disease of the gallbladder, and its incidence is reported to be 1.3%-5.2% [1]. XGC is diagnosed by histopathological examination, characterized by severe inflammatory destruction followed by a granulomatous reaction, marked proliferative fibrosis, and infiltration of inflammatory cells [2].
