Abstract Joule heating and radiative cooling usually play key roles in high‐latitude thermospheric temperature changes during geomagnetic storms. In the mesosphere lower thermosphere (MLT), however, causes of storm‐time at high latitudes are still elusive. Here, we elucidate nature mechanisms MLT variations 10 September 2005 storm by diagnostically analyzing thermodynamics Thermosphere Ionosphere Mesosphere Electrodynamics General Circulation Model (TIMEGCM) simulations. storm's initial main...
Abstract. The dry–hot valley ecosystem of Jinsha River (JS) is a non-zonal special heat island habitat within the global temperate region. Revealing CO2 flux (Fc) changes and response mechanisms this to environmental factors crucial for accurately predicting carbon (C) sequestration capacity terrestrial ecosystems, especially under future extreme-drought climate conditions. We focused on open savanna, which core component JS plant community, as our research subject. Using static chamber...
Abstract Observations by the Sounding of Atmosphere using Broadband Emission Radiometry (SABER) and simulations Whole Community Climate Model‐eXtended (WACCM‐X) are used to analyze impacts January 2012 solar proton events (SPEs) on mesospheric ozone at high latitudes. The latitudes decreased evidently with increasing flux ionization rates during SPEs. results SABER WACCM‐X both showed that maximum depletion reached 100% in North Hemispheric (NH) SPEs while only 40% South (SH) SPEs‐caused...
Pregnancy outcomes and perinatal diseases of children conceived by assisted reproductive technology (ART) spontaneous conception (SC) are still unclear. We sought to compare the effects ART SC on adverse neonatal outcomes. included 5,913 neonates admitted intensive care unit (NICU) First Affiliated Hospital University Science Technology China between January 2017 December 2020. There were 1,112 (18.8%) pregnancies 4,801 (81.2%) pregnancies. Data maternal characteristics, comorbidities during...
The Yunnan–Kweichow Plateau serves as a critical ecological security barrier in southwest China. region has witnessed substantial transformations land use patterns due to rapid urban expansion, economic development, and population growth. These changes have significantly impacted the structure services of regional ecosystems. Conducting quantitative analysis influence land-use on ecosystem service value (ESV) proves be invaluable for guiding planning environmental conservation efforts....
The assessment of soil erosion in a region can provide an effective reference for local ecological environment management. Yunnan–Guizhou Plateau54 is important security barrier southwest China, owing to its unique climatic and environmental characteristics superior natural resource endowment. current research focus the spatial analysis certain area. In this study, Plateau during 2000–2030 was analyzed predicted from two aspects structure layout by coupling several models. report also...
Head breakage is a serious complication following total hip arthroplasty when using Ceramic on bearings surfaces. There still in controversy about the selection of bearing surfaces conducting revision surgery. We describe case fifty-year-old man who had undergone right (THA) with ceramic-on-ceramic prostheses 2011. After fall 6 years after primary procedures, radiographs suggested ceramic head for THA exchange metal-on-polyethylene bearing. However, 8 months later, severe metallosis and...
Skarn Sn-polymetallic deposits, located in the southern Great Khingan Range, can be divided into Sn–Fe and Sn–Pb–Zn deposits. By systematically studying geochemical characteristics of source granitoid ore-forming mechanisms were established, differences processes between deposits are discussed. The main findings as follows: (1) these two formed Late-Yanshanian period; (2) evolved at an early stage a reducing environment, while oxygen fugacity increased late through influence deep-seated...
The impact of the annual solar eclipse, starting on 21st June 2020, attributable to surface ozone concentration (O 3 ) has been investigated in this study. To estimate influence eclipse O better, variations one reaction precursor production [nitrogen dioxide (NO 2 )], coupled with meteorological factors (including Total Solar Irradiance (TSI), Temperature (T), and Relative Humidity (RH)), were analyzed Yunnan Province, China. results show observed decreases from beginning reaching its...
Fulminant myocarditis (FM) is an inflammatory process of the myocardium and important cause cardiac dysfunction in children; it characterized by rapid onset, acute progression, high mortality. The study sought to describe clinical characteristics prognostic factors children with FM. population consists 37 consecutive patients admitted from May 2014 December 2021 a diagnosis According prognosis FM during hospitalization, they were divided into "survival" group (25 cases) "death" (12 cases). A...
Using the temperature data observed from Sounding of Atmosphere using Broadband Emission Radiometry (SABER), we investigate response mesosphere and lower thermosphere (MLT) to two medium geomagnetic storms with disparate durations, on 20 April 2018 10 2022. The high-latitude MLT increase in Southern hemisphere can reach 40 K during storm a longer duration (Kp values greater than 4 for 15 h), while variations are less 2022 event 6 h). To different responses durations understand what physical...
Microwave Limb Sounder (MLS) observations showed an obvious variation of ozone concentration during the annular solar eclipse on 21 June 2020 in mesosphere and upper stratosphere. Ozone slightly reduced near 40 km regions 24°N–36°N, increased low latitudes at km. In heights 45–60 km, increase most was obvious. The increases decreases were more between 60–65 where enhancement took leading role. nighttime weaker than daytime 30–65 HO2 CO is investigated to study photochemical dynamical causes...
Abstract. The dry-hot valley of Jinsha River is distinguished by prolonged drought and high temperatures, making it a distinct non-zonal hot island habitat in the global temperate zone. It an ideal location for studying changes plant carbon budget under sustained high-temperature conditions. However, there currently dearth reports on CO2 flux variations within ecosystems this region. study quantitatively analyzed characteristics variation grassland ecosystem region its response mechanisms to...
