A CNN-SVR model for NO(2) profile prediction based on MAX-DOAS observations: The influence of Chinese New Year overlapping the 2020 COVID-19 lockdown on vertical distributions of tropospheric NO(2) in Nanjing, China

Date
Monday, February 26, 2024 - 4:00 AM
Description
In this study, a hybrid model, the convolutional neural network-support vector regression model, was adopted to achieve prediction of the NO(2) profile in Nanjing from January 2019 to March 2021. Given the sudden decline in NO(2) in February 2020

Impact of Chronic HIV Infection on Acute Immune Responses to SARS-CoV-2

Date
Monday, February 26, 2024 - 4:00 AM
Description
There is mounting evidence that HIV infection is a risk factor for severe presentations of COVID-19. We hypothesized that the persistent immune activation associated with chronic HIV infection contributes to worsened outcomes during acute COVID-19

A Broad-Spectrum Multi-Antigen mRNA/LNP-Based Pan-Coronavirus Vaccine Induced Potent Cross-Protective Immunity Against Infection and Disease Caused by Highly Pathogenic and Heavily Spike-Mutated SARS-CoV-2 Variants of Concern in the Syrian Hamster Model

Date
Monday, February 26, 2024 - 4:00 AM
Description
The first-generation Spike-alone-based COVID-19 vaccines have successfully contributed to reducing the risk of hospitalization, serious illness, and death caused by SARS-CoV-2 infections. However, waning immunity induced by these vaccines failed to
