This paper presents vCerberus, a novel hypervisor to provide trusted and isolated code execution within virtual domains vCerberus is considerably tiny, while allowing secure sensitive codes to be executed in an isolated circumstance from the virtual ddmain, and can be attested by a remote party in an efficient way. These properties will be guaranteed even if the guest operating system is malicious. This protects the secure sensitive codes against the malicious codes in the Guest OS, e.g., the kernel rootkits. We present an approach to dynamically measure and isolate the launch environment on the virtual machines based on the para-virtualization technology and a novel virtualization of trusted platform module （TPM）. Our performance experiment result shows that the overhead introduced by vCerberus is minimized; the performance of the launch environment in vCerberus is as competitive as the guest OS running on mainstream hypervisors.

The Chinese expression of the direction and progress of the international rule of law is an important part of showcasing China＇s stand and ideas in international relations, and serves as a major interactive link between the Chinese rule of law and the international rule of law. The progress of the international rule of law rests on the active, full and effective expression of various countries including China, so that it can become more just and rational. In order to express itself explicitly and effectively, China needs to participate actively in the practices of international rule of law, in a bid to expand its horizon, enlist public support, and obtain opportunities.

由电弧烧蚀触头材料而引起触头失效是导致微型断路器电寿命劣化的主要原因,研究微型断路器电寿命评估方法对提高用电网络安全性和可靠性具有重要意义。该文以额定电流16A的微型断路器作为电寿命试验对象,利用高速摄像机观察触头间电弧的运动过程,从电弧电压中提取反映断路器电寿命退化过程的特征量,研究累积燃弧能量、跌落时间与触头烧蚀量之间的对应关系,并利用这两个趋势特征量构建微型断路器电寿命评估模型。研究结果表明,电压跌落时间具有随开断次数增加而增大的趋势。利用试验数据对模型评估准确度进行测试,测试结果表明,该文提出的方法适用不同开断电流的情形,可以用于微型断路器电寿命的评估,评估误差在可接受范围内。

UBE2C(Ubiquitin conjugating enzyme E2 C), a key regulator of cell cycle progression, is a promising target for discovery of antitumor agents. However, it is challenging to develop inhibitors of UBE2C owing to its lack of “druggable” pockets. Bio PROTACs(biological proteolysis targeting chimeras) are a kind of protein-based degraders by fusing an adaptor to a subunit of E3 ligase for ubiquitination and subsequent proteasome-dependent degradation of target protein. We report herein the design and biological evaluation of a UBE2C-targeting bio PROTAC based on the NEL(novel E3 ligase) domain of bacterial E3 ligase Ipa H9.8 and the UBE2C-binding WHB(winged-helix B) domain of APC_(2)(anaphase promoting complex subunit 2). The in vitro ubiquitination test and Mass Spectrometry analysis showed that the bio PROTAC could transfer ubiquitin to surface exposed lysines on UBE2C and catalyzed the formation of polyubiquitin chains. In addition, the transient co-expression experiment showed that the bio PROTAC could promote proteasomal degradation of heterologous UBE2C and rescue its downstream substrates in mammalian cells.
