Fast radio bursts (FRBs), millisecond-duration bursts prevailing in the radio sky, are the
latest large puzzle in the Universe and have been a subject of intense observational and …

SARS coronavirus 2 (SARS-CoV-2), the causative agent of COVID-19, emerged in China in
December 2019. Vaccines developed were very effective initially, however, the virus has …

SARS-CoV-2 spike glycoprotein mediates receptor binding and subsequent membrane
fusion. It exists in a range of conformations, including a closed state unable to bind the ACE2 …

In this Letter, we introduce the concept of dynamical degeneracy splitting to describe the
anisotropic decay behaviors in non-Hermitian systems. We demonstrate that systems with …

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the causative agent of
the devastating global COVID-19 pandemic announced by WHO in March 2020. Through …

To control the ongoing COVID‐19 pandemic, a variety of severe acute respiratory syndrome
coronavirus 2 (SARS‐CoV‐2) vaccines have been developed. However, the rapid mutations …

Hopfions are localized and topologically nontrivial magnetic configurations that have
received considerable attention in recent years. In this Letter, we use a micromagnetic …

Evolutionary and functional studies suggested that the emergence of the Omicron variants
can be determined by multiple fitness trade-offs including the immune escape, binding …

Summary Background A SARS-CoV-2 protein-based heterodimer vaccine, PHH-1V, has
been shown to be safe and well-tolerated in healthy young adults in a first-in-human, Phase …

The new generation of SARS-CoV-2 Omicron variants displayed a significant growth
advantage and increased viral fitness by acquiring convergent mutations, suggesting that …
