Abstract The public health interventions to mitigate coronavirus disease 2019 (COVID‐19) could also potentially reduce the global activity of influenza. However, this strategy's impact on other common infectious diseases is unknown. We collected data 10 respiratory (RI) diseases, influenza‐like illnesses (ILIs), and seven gastrointestinal (GI) during 2015–2020 in China applied two proportional tests check differences yearly incidence mortality, case‐fatality rates (CFRs) over years...

In response to the coronavirus disease 2019 (COVID-19) pandemic, Chinese government implemented dynamic COVID-zero strategy. We hypothesized that pandemic mitigation measures might have reduced incidence, mortality rates, and case fatality ratios (CFRs) of human immunodeficiency virus (HIV) in 2020-2022.

ABSTRACT Using the daily precipitation records during 1961–2013 from 686 meteorological stations across China and atmospheric circulation indexes, this study investigates spatio‐temporal changes in occurrence time length of extreme period (EPP), as well their influencing factors. The results show following aspects: (1) In last 53 years, start dates (EPPS) generally advanced. end (EPPE) are delayed, which an increasing trend. lengths (EPPL) most increased. (2) spatial patterns trends similar...

Abstract Soil hydraulic parameters are vital for precisely characterizing soil hydrological processes, which critical indicators regulating climate change effects on terrestrial ecosystems and governing feedbacks between water, energy, carbon–nitrogen cycles. Although many studies have integrated comprehensive datasets, data quality cost challenges result in completeness deficiencies, especially deep information. These gaps not only impede methodological endeavours but also constrain...

Abstract. Lack of reliable long-term precipitation record from northern Tibetan Plateau has constrained the understanding variation in this region. An ice core drilled Puruogangri Ice Field on central year 2000 helped reveal variations since AD 1600. Analysis annual accumulation data presented changes 1600, indicative wet and dry periods past 400 Plateau. Accordingly, 18th 20th centuries experienced high period, whilst 19th century low period. Such a feature was consistent with recorded...

Time-lapse (4D) seismic is a tried and tested method to monitor fluid changes in producing reservoir, but its effectiveness reliability depend on the quality repeatability of surveys. It still has significant limitations when applied land for monitoring some deep reservoirs (depth >1000 m) where production rates are low many other factors unfavorable effective 4D acquisition, processing, interpretation. Modern high-density, wide-azimuth, multi-component data-acquisition techniques have...

The incidence of scarlet fever and pertussis has increased significantly in China recent years. During the COVID-19 pandemic, stringent non-pharmaceutical intervention measures were widely adopted to contain spread virus, which may also have essential collateral impacts on other infectious diseases, such as pertussis. We compared data Mainland Hong Kong from 2004 2021 before after pandemic. results show that both diseases decreased 2020–2021 after-re-emergence stage these two locations....
