The Devastating 2022 M6.2 Afghanistan Earthquake: Challenges, Processes, and Implications
On June 21st, a Mw6.2 earthquake struck the Afghan-Pakistan-border-region, situated within the India-Asia collision. Thousand thirty-nine deaths were reported, making the earthquake the deadliest of 2022. We investigate the event\u27s rupture processes by combining seismological and geodetic observations, aiming to understand what made it that fatal. Our Interferometric Synthetic Aperture Radar-constrained slip-model and regional moment-tensor inversion, confirmed through field observations, reveal a sinistral rupture with maximum slip of 1.8 m at 5 km depth on a N20°E striking, sub-vertical fault. We suggest that not only external factors (event-time, building stock) but fault-specific factors made the event excessively destructive. Surface rupture was favored by the rock foliation, coinciding with the fault strike. The distribution of Peak-Ground-Velocity was governed by the sub-vertical fault. Maximum slip was large compared to other events globally and might have resulted in peak-frequencies coinciding with resonance-frequencies of the local buildings and demonstrates the devastating impact of moderate-size earthquakes
Proactive Maintenance Strategy Based on Resilience Empowerment for Complex Buildings
Resilience of the built environment, particularly in complex buildings, is strictly related to the effectiveness of systems and sub-systems that provide the expected features to manage risk scenarios in routine and non-routine conditions. In this perspective, maintenance is therefore a key factor to assure building resilience by keeping systems and equipment in the required operational state. Risk management can be empowered if system resilience and disruptive events are monitored in real-time, and, to this aim, proactive maintenance can nowadays monitor systems resilience with innovative digital tools

The impact of Border policy effect on cross-border ethnic areas
Boundary effect analysis is related to border policy making in the cross-border ethnic area. The border effect literatures show that
geographic boundaries have obvious impacts on economic, social and cultural relations in both sides of a nation border. Particularly
in cross-border ethnic areas, each ethnic group has strong internal spatial structure relevance, and the boundary effect is more
obvious. However, most of China's border areas are cross-border ethnic areas, each of border issues is unique. Under this perspective,
we analyze the border effects of various boundaries can provide basis for formulating border management policies. For small scale of
cross-border ethnic minority areas, how to formulate the boundary management policy is a good question to explore. This paper is
demonstrated by a study of the impact of border management policies in Dehong Dai and Jingpo Autonomous Prefecture in Yunnan
Province at the border area to Burma. The comparative method is used to analysis the border management policies in past 50 decades
for the border area of Yunnan Province .This research aims to define trends within border policy and its influences to national
security. This paper also examines Wendy Brown's liberal theory of border management policy. We found that it is not suitable for
Sino-Burma border area. The conclusion is that the changes or instability of international economic and political situation has more
influence to this cross-border ethnic area, and only innovative policy will be effective in cross-border ethnic area. So the border
management policies should reflect the change of international context
Generation and physiological roles of linear ubiquitin chains
Ubiquitination now ranks with phosphorylation as one of the best-studied post-translational modifications of proteins with broad regulatory roles across all of biology. Ubiquitination usually involves the addition of ubiquitin chains to target protein molecules, and these may be of eight different types, seven of which involve the linkage of one of the seven internal lysine (K) residues in one ubiquitin molecule to the carboxy-terminal diglycine of the next. In the eighth, the so-called linear ubiquitin chains, the linkage is between the amino-terminal amino group of methionine on a ubiquitin that is conjugated with a target protein and the carboxy-terminal carboxy group of the incoming ubiquitin. Physiological roles are well established for K48-linked chains, which are essential for signaling proteasomal degradation of proteins, and for K63-linked chains, which play a part in recruitment of DNA repair enzymes, cell signaling and endocytosis. We focus here on linear ubiquitin chains, how they are assembled, and how three different avenues of research have indicated physiological roles for linear ubiquitination in innate and adaptive immunity and suppression of inflammation
