Toward High-quality Face-Mask Occluded Restoration

Face-mask occluded restoration aims at restoring the masked region of a human face, which has attracted increasing attention in the context of the COVID-19 pandemic. One major challenge of this task is the large visual variance of masks in the real world. To solve it we first construct a large-scale Face-mask Occluded Restoration (FMOR) dataset, which contains 5,500 unmasked images and 5,500 face-mask occluded images with various illuminations, and involves 1,100 subjects of different races, face orientations, and mask types. Moreover, we propose a Face-Mask Occluded Detection and Restoration (FMODR) framework, which can detect face-mask regions with large visual variations and restore them to realistic human faces. In particular, our FMODR contains a self-adaptive contextual attention module specifically designed for this task, which is able to exploit the contextual information and correlations of adjacent pixels for achieving high realism of the restored faces, which are however often neglected in existing contextual attention models. Our framework achieves state-of-the-art results of face restoration on three datasets, including CelebA, AR, and our FMOR datasets. Moreover, experimental results on AR and FMOR datasets demonstrate that our framework can significantly improve masked face recognition and verification performance. © 2023 Association for Computing Machinery.

Expert guidance on overall management of liver cancer during the COVID-19.

The pandemic of Corona Virus Disease 2019 (COVID-19) continues, which shows the concentrated or sporadic cases in multiple places. Current COVID situation is still complex. During the COVID-19, routine diagnosis and treatment of liver cancer patients has been affected in different degrees. Under the premise of following the treatment guidelines, how to reduce the risk of infection of patients and medical staff, utilize limited medical resources to maximally ensure anti-tumor treatment and related emergency treatment, and help patients get through the epidemic period is a problem for liver oncologists. Thus, experts of liver cancer treatment related disciplines of Zhongshan Hospital, Fudan University have written the Expert guidance on overall management of liver cancer during the COVID-19, which aims to provide references for liver oncologists to conduct clinical work safely and effectively under the epidemic prevention and control, and to help patients fight against the epidemic smoothly.Copyright © 2022 Chinese Medical Journals Publishing House Co.Ltd.

Innovative design of box elevator epidemic prevention function integrating AD and TRIZ

The large number of indirect contact between people in the narrow space of the box elevator has brought hidden dangers to the spread of COVID-19 (Corona Virus Disease 2019). How to inhibit the survival and spread of the virus in the elevator has become an urgent problem to be solved. Therefore, by analyzing the advantages and disadvantages of axiomatic design (AD) and Tteoriya Resheniya Izoblateskikh Zadatch (TRIZ), an innovative design method integrating AD and TRIZ was proposed for different design types, such as breakthrough design, adaptive design and variable parameter design. Firstly, the function requirements of the product were analyzed to determine its design type, and the function requirements was decomposed by the AD theory, and the function-structure tree was constructed by the TRIZ. Then, the coupling judgment of the initial design scheme was carried out, and the TRIZ was used to decouple. After several iterations, the final design scheme was obtained. Taking the public interactive control panel and the enclosed car of the traditional box elevator as the research object, facing the function requirements of preventing virus transmission and eliminating virus, the innovative design method integrating AD and TRIZ was adopted to design the epidemic prevention function module of the box elevator, and the non-public contact interactive control module and the conditional disinfection and sterilization module for the traditional box elevator were designed. The innovative design example made a beneficial attempt to expand from the traditional mechanical structure design to the new human-computer interaction mode design, which verified the feasibility of the innovative design method integrating AD and TRIZ. The research results can provide effective theoretical support for the conceptual innovative design of new functional modules of products. © 2021. All Rights Reserved.

Current status and future prospect of management of biosafety laboratories for emerging infectious diseases

In recent years, there have been several outbreaks of infectious diseases around the world, including severe acute respiratory syndrome, Ebola virus disease, Middle East respiratory syndrome, and corona virus disease 2019. Experience suggests that the detection and research of emergent infectious diseases play a crucial role in the process of responding to the epidemic, which also brings great challenges to biosafety laboratories. In the face of unknown biological risk factors, the non-standard biosafety protection measures have a serious impact on the life safety of laboratory staff and the research of infectious diseases, which stresses the necessity of safety protection in biosafety laboratories. This article will briefly review the current status and future prospect of management of biosafety laboratories both in China and other countries in terms of safety protection measures during new sudden infectious disease incidents.
