Realization of Supersymmetry and Its Spontaneous Breaking in Quantum Hall Edges.

Supersymmetry (SUSY) relating bosons and fermions plays an important role in unifying different fundamental interactions in particle physics. Since no superpartners of elementary particles have been observed, SUSY, if present, must be broken at low-energy. This makes it important to understand how SUSY is realized and broken, and study their consequences.

A Prospective Study to Identify Rates of SARS-CoV-2 Virus in the Peritoneum and Lower Genital Tract of Patients Having Surgery: An Observational Study.

Study Objective: The risks to surgeons of carrying out aerosol-generating procedures during the coronavirus disease 2019 (COVID-19) pandemic are unknown. To start to define these risks, in a systematic manner, we investigated the presence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus in the abdominal fluid and lower genital tract of patients undergoing surgery.

Design: Prospective cross-sectional observational study.

Thermal Equilibration on the Edges of Topological Liquids.

Thermal conductance has emerged as a powerful probe of topological order in the quantum Hall effect and beyond. The interpretation of experiments crucially depends on the ratio of the sample size and the equilibration length, on which energy exchange among contrapropagating chiral modes becomes significant. We show that at low temperatures the equilibration length diverges as 1/T^{2} for almost all Abelian and non-Abelian topological orders.

Differential contribution of inhibitory phosphorylation of CDC2 and CDK2 for unperturbed cell cycle control and DNA integrity checkpoints.

Inhibition of cyclin-dependent kinases (CDKs) by Thr14/Tyr15 phosphorylation is critical for normal cell cycle progression and is a converging event for several cell cycle checkpoints. In this study, we compared the relative contribution of inhibitory phosphorylation for cyclin A/B1-CDC2 and cyclin A/E-CDK2 complexes. We found that inhibitory phosphorylation plays a major role in the regulation of CDC2 but only a minor role for CDK2 during the unperturbed cell cycle of HeLa cells.
