Abstract We propose a new mechanism for rendering dark matter self-interacting in the presence of a massive spin-2 mediator.The derived Yukawa-type potential for dark matter is independent of the spins of dark matter in the leading order of the momentum expansion, so are the resulting non-perturbative effects for the dark matter Display Boards self
Abstract Background Plant growth Speed Sensor Bracket depends on both cell division and cell expansion.Plant hormones, including brassinosteroids (BRs), are central to the control of these two cellular processes.Despite clear evidence that BRs regulate cell elongation, their roles in cell division have remained elusive.Results Here, we report resul
Abstract Background The emergence of the novel coronavirus in Wuhan, Hubei Province, China, in December 2019 marked the synchronization of the world to a peculiar clock that is counting infected cases and deaths instead of hours and minutes.The pandemic, highly transmissible severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has indeed ca
Background Bleeding from rupture esophageal varices (EV) is a major and life-threatening complication of liver cirrhosis (LC).Early detection of EV and prediction of its bleeding risk is important.Objective To assess and evaluate the resistive index (RI) of the renal artery (RA) by Doppler in SHORTS URBAN various stages of portal hypertensive manif
