Intense nonpharmaceutical interventions were put in place China to stop transmission of the novel coronavirus disease 2019 (COVID-19). As intensifies other countries, interplay between age, contact patterns, social distancing, susceptibility infection, and COVID-19 dynamics remains unclear. To answer these questions, we analyze survey data for Wuhan Shanghai before during outbreak contact-tracing information from Hunan province. Daily contacts reduced seven- eightfold distancing period, with...
Having adopted a dynamic zero-COVID strategy to respond SARS-CoV-2 variants with higher transmissibility since August 2021, China is now considering whether, and for how long, this policy can remain in place. The debate has thus shifted towards the identification of mitigation strategies minimizing disruption healthcare system case nationwide epidemic. To aim, we developed an age-structured stochastic compartmental susceptible-latent-infectious-removed-susceptible model transmission...

Nonpharmaceutical interventions to control SARS-CoV-2 spread have been implemented with different intensity, timing, and impact on transmission. As a result, post-lockdown COVID-19 dynamics are heterogeneous difficult interpret. We describe set of contact surveys performed in four Chinese cities (Wuhan, Shanghai, Shenzhen, Changsha) during the pre-pandemic, lockdown periods quantify changes patterns. In period, mean number contacts increased by 5 17% as compared period. However, it remains...
Abstract Strict interventions were successful to control the novel coronavirus (COVID-19) outbreak in China. As transmission intensifies other countries, interplay between age, contact patterns, social distancing, susceptibility infection and disease, COVID-19 dynamics remains unclear. To answer these questions, we analyze surveys data for Wuhan Shanghai before during tracing information from Hunan Province. Daily contacts reduced 7-9 fold distancing period, with most interactions restricted...
Abstract Background The COVID-19 epidemic originated in Wuhan City of Hubei Province December 2019 and has spread throughout China. Understanding the fast evolving epidemiology transmission dynamics outbreak beyond would provide timely information to guide intervention policy. Methods We collected individual on 8,579 laboratory-confirmed cases from official publically sources reported outside mainland China, as February 17, 2020. estimated temporal variation demographic characteristics key...
Abstract Background Assessing the measles immunity profile is critical for developing effective nationwide or region-wide supplementary immunization activities (SIAs). This study aims to assess population levels in China and investigate factors contributing age-specific heterogeneities. Methods We conducted a cross-sectional population-based serological southern between June October 2021. determined mean antibody concentration seroprevalence by age over time, along with their associated...
The coronavirus disease 2019 (COVID-19) pandemic and the measures taken by authorities to control its spread have altered human behavior mobility patterns in an unprecedented way. However, it remains unclear whether population response a COVID-19 outbreak varies within city or among demographic groups. Here, we utilized passively recorded cellular signaling data at spatial resolution of 1 km × for over 5 million users epidemiological surveillance collected during severe acute respiratory...
Abstract Non-pharmaceutical interventions to control COVID-19 spread have been implemented in several countries with different intensity, timing, and impact on transmission. As a result, post-lockdown dynamics are heterogenous difficult interpret. Here we describe set of contact surveys performed four Chinese cities (Wuhan, Shanghai, Shenzhen, Changsha) during the pre-pandemic, lockdown, period quantify transmission relaxing via changes age-specific patterns. We estimate that mean number...
Previous studies have demonstrated significant changes in social contacts during the first-wave coronavirus disease 2019 (COVID-19) Chinese mainland. The purpose of this study was to quantify time-varying contact patterns by age mainland 2020 and evaluate their impact on transmission severe acute respiratory syndrome 2 (SARS-CoV-2).Diary-based surveys were performed for four periods: baseline (prior 2020), outbreak (February post-lockdown (March-May post-epidemic (September-November 2020)....
Abstract Background The economic burden of respiratory syncytial virus (RSV) infection and its impact on health‐related quality life (HRQoL) are not well‐understood in China. This study assessed total cost HRQoL for children hospitalized with RSV Central Methods Based a prospective case series Henan Province 2020–2021, inpatients aged 0–59 months RSV‐related acute infections (ARIs) were included into analysis. Total direct medical (sum before during hospitalization), non‐medical cost,...
Social contact patterns significantly influence the transmission dynamics of respiratory pathogens. Previous surveys have quantified human social patterns, yielding heterogeneous results across different locations. However, significant gaps remain in understanding rural areas China. We conducted a pioneering study to quantify Anhua County, Hunan Province, China, from June October 2021, when there were minimal coronavirus disease-related restrictions area. Additionally, we simulated epidemics...
Background: Long non-coding RNA (lncRNA) participates in the immune regulation of lung cancer. However, limited studies showed potential roles immune-related lncRNAs (IRLs) predicting survival and immunotherapy response adenocarcinoma (LUAD). Methods: Based on The Cancer Genome Atlas (TCGA) ImmLnc databases, IRLs were identified through weighted gene coexpression network analysis (WGCNA), Cox regression, Lasso regression analyses. predictive ability was validated by Kaplan−Meier (KM)...

In this paper, the analysis of nearly invariant subspaces and kernels Toeplitz operators on Hardy space over bidisk is developed. Firstly, we transcribe Chalendar, Chevrot Partington's result to vector-valued $H^{2}_{\ma{H}}(\mathbb{D})$ when $\ma{H}$ an infinite dimensional separable complex Hilbert space. Secondly, explore definition bidisk, apply it characterize operators. Finally, define for commutative isometric tuples, which allows us show that kernel general also invariant.
This paper characterises the subspaces of $H^2(\mathbb D)$ simultaneously invariant under $S^2 $ and $S^{2k+1}$, where $S$ is unilateral shift, then further identifies that are nearly both $(S^2)^*$ $(S^{2k+1})^*$ for $k\geq 1$. More generally, (nearly) with respect to $(S^m)^*$ $(S^{km+\gamma})^*$ characterised $m\geq 3$, 1$ $\gamma\in \{1,2,\cdots, m-1\},$ which leads a description higher order shifts. Finally, corresponding results Toeplitz operators induced by Blaschke product presented....
