Extreme space weather events caused by super active regions during solar cycles 21-24 [PDF]
, 2021 Extreme space weather events including $\ge$X5.0 flares, ground level enhancement (GLE) events and super geomagnetic storms (Dst $\le$ -250 nT) caused by super active regions (SARs) during solar cycles 21-24 were studied. The total number of $\ge$X5.0 solar flares was 62, 41 of them were X5.0-X9.9 flares and 21 of them were $\ge$X10.0 flares.

Nature Communications, 2020 Since 2002, beta coronaviruses (CoV) have caused three zoonotic outbreaks, SARS-CoV in 2002–2003, MERS-CoV in 2012, and the newly emerged SARS-CoV-2 in late 2019. However, little is currently known about the biology of SARS-CoV-2.

Protease inhibitors targeting coronavirus and filovirus entry. [PDF]
, 2015 In order to gain entry into cells, diverse viruses, including Ebola virus, SARS-coronavirus and the emerging MERS-coronavirus, depend on activation of their envelope glycoproteins by host cell proteases.

Differentiable SAR Renderer and SAR Target Reconstruction [PDF]
, 2022 Forward modeling of wave scattering and radar imaging mechanisms is the key to information extraction from synthetic aperture radar (SAR) images. Like inverse graphics in optical domain, an inherently-integrated forward-inverse approach would be promising for SAR advanced information retrieval and target reconstruction.

Cell entry mechanisms of SARS-CoV-2
Proceedings of the National Academy of Sciences of the United States of America, 2020 Significance A key to curbing SARS-CoV-2 is to understand how it enters cells. SARS-CoV-2 and SARS-CoV both use human ACE2 as entry receptor and human proteases as entry activators.

BMC Genomics, 2018 Background Development is largely driven by transitions between transcriptional programs. The initiation of transcription at appropriate sites in the genome is a key component of this and yet few rules governing selection are known.

Oil Spill SAR Image Segmentation via Probability Distribution Modelling [PDF]
arXiv, 2021 Segmentation of marine oil spills in Synthetic Aperture Radar (SAR) images is a challenging task because of the complexity and irregularities in SAR images. In this work, we aim to develop an effective segmentation method which addresses marine oil spill identification in SAR images by investigating the distribution representation of SAR images.

Nature Microbiology, 2020 Over the past 20 years, several coronaviruses have crossed the species barrier into humans, causing outbreaks of severe, and often fatal, respiratory illness. Since SARS-CoV was first identified in animal markets, global viromics projects have discovered
