网络暴力是一种涵盖网络语言暴力、捏造传播网络谣言和人肉搜索行为的侵犯他人权益的社会现象。随着信息网络技术的发展呈现出井喷态势,极大地破坏了网络安全环境、严重地侵犯了公民的合法权益。但我国现有的法律规范体系在应对网络暴... 详细信息

网络暴力是一种涵盖网络语言暴力、捏造传播网络谣言和人肉搜索行为的侵犯他人权益的社会现象。随着信息网络技术的发展呈现出井喷态势,极大地破坏了网络安全环境、严重地侵犯了公民的合法权益。但我国现有的法律规范体系在应对网络暴力时略显不足。民法行政法等法律规范力度较弱,刑法中部分罪名的构成要件又与网络暴力行为不相一致导致网络暴力难以入刑。为有效应对日趋严重的网络暴力现象,一是应当出台司法解释,明确网络暴力犯罪的构成要件和适用情形,并纳入现行刑法体系予以规制;二是完善亲告罪自诉转公诉程序,明确司法机关主动介入的依据和标准,弥合亲告罪自诉转公诉程序之缺陷,有效保障被害人的合法权益。

During the 10th Chinese Arctic scientific expedition carried out in the summer of 2019,the surface current in the high-latitude areas of the Arctic Ocean was observed using a self-developed surface drifting buoy,which was initially deployed in the Chukchi *** buoy traversed the Chukchi Sea,Chukchi Abyssal Plain,Mendeleev Ridge,Makarov Basin,and Canada Basin over a period of 632 *** returning to the Mendeleev Ridge,it continued to drift toward the ***,the track of the buoy reflected the characteristics of the transpolar drift and Chukchi Slope Current,as well as the inertial flow,cross-ridge surface flow,and even the surface disorganized flow for some time *** results showed that:(1)the transpolar drift mainly occurs in the Chukchi Abyssal Plain,Mendeleev Ridge,and western Canada Basin to the east of the ridge where sea ice concentration is high,and the average northward flow velocity in the region between 79.41°N and 86.32°N was 5.1 cm/s;(2)the average surface velocity of the Chukchi Slope Current was 13.5 cm/s,and while this current moves westward along the continental slope,it also extends northwestward across the continental slope and flows to the deep sea;and(3)when sea ice concentration was less than 50%,the inertial flow was more significant(the maximum observed inertial flow was 26 cm/s,and the radius of the inertia circle was 3.6 km).

Commercial computers based on electronic logic devices have brought great changes to the world. However, traditional electronic devices are suffering from numerous technical challenges in their attempts to continue to satisfy Moore's law. Alloptical logic devices, as promising successors to their electronic counterparts, have become a major focus of optics research. In this paper, we provide a review of current all-optical logic devices. The logic gates in these devices, which are described in the first part of the review, are divided into five categories based on the different principles used in their realization. Complex optical devices with various functions and reconfigurable devices are summarized in the next section. In the final part of this paper, we discuss some of the previous works on all-optical integrated chips with specific functions. This review will provide a complete technological roadmap for all-optical devices and aims to be helpful in possible future developments in this growing field.
