Long term ground movements above a tunnel may continue to increase with time after tunnelling in clayey soils as the tunnellinginduced excess pore water pressures dissipate,whilst the changing earth pressure acting on the tunnel leads to further tunnel deformation during *** the tunnel itself introduces new drainage conditions;that is,depending on the drainage condition of the tunnel lining,the effective stresses around the tunnel change with time,inducing further soil consolidation.A seepage rate from low permeability clayey soil is often very small and the groundwater seeping into the tunnel can evaporate *** a tunnel may look impermeable because the surface looks dry,it is possible that the tunnel drainage conditions are actually *** paper summarises the investigation of soil-tunnel consolidation interaction,particularly focusing on ground surface movements and tunnel lining deformation in the interest of engineering *** results show that tunnel lining permittivity relative to the permeability of the surrounding ground plays an important role on both long-term ground movements as well as tunnel lining *** findings published in literature are reviewed step by step starting from a single tunnel,twin tunnels to complex cross passage *** mechanisms of tunnelling-induced soil consolidation for these structures are identified and,where applicable,possible engineering methodologies to assess the magnitude of long-term ground surface settlements and tunnel lining loads are proposed.

The COVID-19 Outbreak in South Korea: Lessons to Be Learned

Advances in Infectious Diseases 2022年第2期12卷 298-311页

The Coronavirus 2019 (COVID-19) is a novel type of coronavirus-related disease that has over 4 million confirmed cases worldwide as of May 13th, 2020. With over 200 countries impacted by the pandemic, many countries have taken drastic measures such as temporary closure of international borders. The purpose of this thesis is to examine the South Korean response to COVID-19 and the keys to successful containment of the disease. Real time analysis was performed on data provided by the Centers for Disease Control (CDC). Comparisons of disease containment among countries with the highest confirmed cases were normalized for population size differences by taking the proportion of confirmed cases to population size. We further compared the disease outbreak in Seoul, a very urban environment, to the whole country of South Korea, to compare public health in urban and rural environments. We found that the efficient partnership between the private sector and the state led to rapid development in testing kits, which was integral to the South Korean response to COVID-19. In addition, the South Koreans’ community spirit, approval of government-led interventions, and societal norm of wearing masks were also efficient social responses to the spreading disease. In this paper, we navigate the impacts of a universal healthcare system and its ability to battle infectious diseases and the efficacy of various governmental actions in response to a public health crisis.

Revisiting the intraseasonal,interannual and interdecadal variability of tropical cyclones in the western North Pacific

引用

Atmospheric and Oceanic Science Letters 2018年第2期11卷 198-208页

作者： LI richard C.Y. ZHOU Wen City University of Hong kong Shenzhen Research Institute Shenzhen China School of Energy and Environment Guy Carpenter Asia-Pacific Climate Impact Center City University of Hong Kong Hong Kong China

This paper reviews the recent progress and research on the variability of tropical cyclones(TCs) at different time scales. Specific focus is placed on how different types of external forcings or climatic oscillations contribute to TC variability in the western North Pacific(WNP). At the intraseasonal scale, recent advances on the distinctive impacts of the Madden–Julian Oscillation(MJO), the Quasi-biweekly Oscillation, and the asymmetric MJO modulation under different El Ni?o–Southern Oscillation(ENSO) states, as well as the influences of the Pacific–Japan teleconnection, are highlighted. Interannually, recent progress on the influences of the ENSO cycle, different flavors of ENSO, and impacts of Indian Ocean warming is presented. In addition, the uncertainty concerning interdecadal TC variations is discussed, along with the recently proposed modulation mechanisms related to the zonal sea surface temperature gradient, the North Pacific Gyre Oscillation, and the Pacific Decadal Oscillation(PDO). It is hoped that this study can deepen our understanding and provide information that the scientific community can use to improve the seasonal forecasting of TCs in the WNP.

Dear Editor, This letter considers the control problem of an experimental flexible manipulator in position tracking, vibration suppression, and saturation compensation. Based on the backstepping technology and a Nussbaum function, we develop an anti-windup control to restrain the manipulator’s vibration, realize the desire trajectory tracking, and eliminate the saturation.

＜正＞硅藻骨条藻（Skeletonema costatum）分布广泛,是常见的海洋浮游植物。作为初级生产者,在海洋食物链中起着重要作用。酚类物质是常见的环境污染物,它们的致毒机理被认为是解偶联氧化磷酸化。然而文献中显示酚及其衍生物（如甲基、卤代、硝基等）抑制藻类生长的同时,并未抑制细胞ATP的水平,因此酚类对藻类的毒性机理仍未明瞭。
