The Asian monsoon(AM) region is a well-known region with prevailing stratosphere–troposphere exchange(STE).However,how the STE across this region changes with the weakening AM remains ***,we particularly diagnose the air mass transport between the planetary boundary layer(PBL) and the stratosphere over the AM region during 1992.2.17 using the Lagrangian particle dispersion model FLEXPART based on the ERA-Interim reanalysis *** results show that both the downward and upward deep STEs exhibit a detectable increasing trend,while the latter,namely,the deep troposphere-to-stratosphere transport(DTST),is relatively more *** analysis reveals that the long-term trend of DTST over the AM region could be partly attributed to changes in the Pacific Walker circulation and the air temperature(especially at upper levels).Additionally,it is found that DTST increases markedly over the tropical oceanic regions,while the increasing DTST into the stratosphere can be attributed to the enhanced air masses originated from the PBL over the terrestrial regions,where large amounts of pollutant emissions *** results imply that the influence of the DTST on the chemical composition and the climate of the stratosphere over the AM region is expected to become increasingly important,and is thereby of relevance to climate projection in an evolving climate.

Precipitation provides water resources but can also cause disasters. The amount, intensity, and frequency of precipitation have significant impacts on ecosystems, people’s health, and socioeconomic systems [1]. However, due to its spatiotemporal discontinuity, accurately estimating precipitation remains a great challenge[2.. To estimate global precipitation at the required spatial and temporal resolutions, active microwave and passive microwave(PMW) observations from low-Earth-orbit satellites and infrared observations from geostationary satellites must be *** Integrated Multi-satellite Retrievals for Global Precipitation Measurement (IMERG) product is one of the best such products and provides global precipitation data at 0.1°and half-hour resolutions [3].

随着人类社会经济的逐步发展和社会分工的不断细化,刑事诉讼活动也开始了横向整合和纵向深入的演变过程。通过对大量的事实进行价值分析和规范衡量,可以发现在刑事诉讼制度的演进发展过程中,国家干预正逐步向社会自治过渡,世界范围内的刑事诉讼制度随之也经历了四次根本性转折:司法权与行政权的分离、控审分离、控辩平等、控辩合作。以“国家—社会”为基点,以分权制衡为工具进行观察,可以发现这四次革命在保障人权和惩罚犯罪的过程中,逐步实现正当性、均衡性与规范性,促进刑事司法权力和权利场域日臻善治,并不断实现保障人权和惩罚犯罪的平衡。

认罪认罚从宽制度是习近平法治思想在深化司法体制改革中的具体表现,是构建中国特色社会主义法治体系的重要举措。对该项具有鲜明中国特色的刑事司法制度,应从纵横两个维度予以观察。从横向的世界各国制度视野看,我国的认罪认罚从宽制度具有独特的司法理念价值取向和制度体系建构。从纵向的刑事诉讼四次革命历史看,刑事诉讼制度的发展基本上都是以权力与权力、权力与权利的制衡理论为指引,围绕着辩护权的扩张与公权力的限缩逐步推进。沉默权缺位、辩方知情权不足、有效辩护缺位违背了控辩协商必须与证据开示、沉默权保障共生共长的孪生制度构建原理。从系统性以及完整性两个角度看,我国当下的认罪认罚从宽制度迈出了控辩协商“简者更简”的第一步,而要让“每个人民群众在司法案件中感受到公平正义”亟需迈出“繁者更繁”的第二步,以推动加快建设公正高效权威的社会主义司法制度,践行习近平法治思想公平正义观。

We revisited the vortex states of 2.-NbSe_(2. towards zero fields by a low-temperature scanning tunneling *** structures of the anisotropic vortex states were distinguished, one is a spatially non-splitting zero bias peak, and the other is an in-gap conductance anomaly resembling evolved crossing features around the center of the three nearest *** of them distribute solely along the next nearest neighboring direction of the vortex lattice and become unresolved in much higher magnetic fields, implying an important role played by the vortex–vortex interactions. To clarify these issues,we have studied the intrinsic vortex states of the isolated trapped vortex in zero fields at 0.45 K. It is concluded that the anisotropic zero bias peak is attributed to the superconducting gap anisotropy, and the spatially evolved crossing features are related to the vortex–vortex interaction. The vortex core size under the zero-field limit is determined. These results provide a paradigm for studying the inherent vortex states of type-II superconductors especially based on an isolated vortex.
