Abstract. A 6-year-long high-resolution Chinese air quality reanalysis (CAQRA) dataset is presented in this study obtained from the assimilation of surface observations China National Environmental Monitoring Centre (CNEMC) using ensemble Kalman filter (EnKF) and Nested Air Quality Prediction Modeling System (NAQPMS).This contains fields six conventional pollutants (i.e. PM2.5, PM10, SO2, NO2, CO, O3) for period 2013–2018 at high spatial (15 km×15 km) temporal (1 h) resolutions. This paper...
Importance Recent studies have suggested an association between nonarteritic anterior ischemic optic neuropathy (NAION) with semaglutide usage. However, the limitations of those analyses warrant further investigation, given frequency use these medications in people and without diabetes. Objective To investigate risk NAION among patients Design, Setting, Participants This cohort study used data from TriNetX database October 1, 2019, December 31, 2023, to identify diabetes no history who were...
Increasing ozone concentrations are becoming a severe problem for air pollution in China and have an adverse impact on human health. Here we evaluate premature deaths attributable to long-term exposure ambient between 2013 2017 with quality model at 5 km resolution the latest estimates of relative risk We use modified inverse distance weighting method bias-correct key model-simulated metrics. find that 5-year average basis there 186,000 (95% Confidence Interval: 129,000-237,000) respiratory...
Abstract The second version of Chinese Academy Sciences Earth System Model (CAS‐ESM 2) is described with emphasis on the development process, strength and weakness, climate sensitivities in simulations Coupled Intercomparison Project (CMIP6) DECK experiments. CAS‐ESM 2 was built as a numerical model to simulate both physical system well atmospheric chemistry carbon cycle. It newcomer international modeling community provide sufficiently independent solutions from those other models....
Ozone source–receptor relationships over East Asia have been quantitatively investigated using a chemical transport model including an on-line tracer-tagged procedure, with particular focus on the source regions of different daily ozone mixing ratios. Comparison observations showed that reproduced surface and tropospheric nitrogen dioxide column densities. Long-range from outside contributed greatest fraction to annual remote regions, Korean peninsula, Japan, reaching 50%–80% total ozone....
Explosive growth in mega-scale data centers drives switch chips to transition from 12.8Tb/s 51.2Tb/s throughput. A requires 512 lanes operating at 106Gb/s PAM-4. Such a massive integration of electrical SERDES is restrained by three factors: First, large die size (>25×25mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> ) substantially lowers yield and prohibitively increases cost. Second, large-size package suffers more than 10dB...
To study the feasibility of creating a radiocephalic hemodialysis fistula in elderly and diabetic patients, we prospectively studied 176 patients undergoing first permanent vascular access creation followed outcome until primary failure or success was assessed. Color duplex ultrasonography used to measure blood flow rate. Fistula rate significantly smaller however, it > 400 ml/min over 78% with successful fistulas. There no difference between nondiabetics diabetics. Dialysis adequacy (Kt/V)...
Abstract. Eolian dust transport and deposition are important geophysical processes which influence global bio-geochemical cycles. Currently, reliable data scarce in central east Asia. Located at the boundary of Asia, Xinjiang Province northwestern China has long played a strategic role cultural economic trade between Asia Europe. In this paper, we investigated spatial distribution temporal variation ambient PM10 (particulate matter aerodynamic diameter ≤ 10 µm) concentration from 2000 to...
Biogenic secondary organic aerosols (SOA) are generally considered to be more abundant in summer than winter. Here, polar marker compounds urban background from Mumbai were measured using gas chromatography–mass spectrometry. Surprisingly, we found that concentrations of biogenic SOA tracers at several times lower (8–14 June 2006; wet season; n = 14) winter (13–18 February 2007; dry 10). Although samples less 10% the season extrapolated full season, such seasonality may explained by...
Abstract Soil organic carbon (SOC) dynamics in croplands is a crucial component of global (C) cycle. Depending on local environmental conditions and management practices, typical C input generally required to reduce or reverse loss agricultural soils. No studies have quantified the critical for maintaining SOC at scale with high resolution. Such information will provide baseline map assessing soil under potential changes practices climate thus enable development strategies footprint from...
Importance The long-term estimated risk of development cataracts among pediatric patients with uveitis is not clear. Objective To describe factors associated the uveitis. Design, Setting, and Participants This cohort study used international TriNetX database to enroll without from January 1, 2002, December 31, 2022. nonuveitis consisted randomly selected control matched by age, sex, race ethnicity, specific comorbidities. Exposure Diagnosis uveitis, identified using diagnostic codes. Main...
Abstract. The GNAQPMS model is the global version of Nested Air Quality Prediction Modelling System (NAQPMS), which a multi-scale chemical transport used for air quality forecast and atmospheric environmental research. In this study, we present our work porting optimizing on second generation Intel Xeon Phi processor codename “Knights Landing” (KNL). Compared with first coprocessor, KNL introduced many new hardware features such as bootable processor, high performance in-package memory ISA...
We developed a new modeling framework to simulate aerosol microphysics by incorporating volatility basis-set (VBS) organic (OA) module into three-dimensional (3-D) atmospheric transport model, namely, Nested Air Quality Prediction Modeling System with an Advanced Particle Microphysics (NAQPMS + APM). The model calculates not only the condensation of sulfuric acid, nitrate, and ammonium coagulation five types particles (namely secondary, sea salt, dust, black carbon particles) but also...
Background: Dialysis patients with uremic pruritus have worse outcomes. However, the pathophysiology of high mortality in these remains inconclusive except for links calcium/phosphate imbalance and sleep disturbance. Whether inflammation, an outcome predictor dialysis patients, plays a role is unknown.
In this study, we try to compare the benefit of laparoscopic versus open operative procedures. Patients and Methods . One hundred sixteen patients underwent liver resection (LR) another 208 went for (OR) hepatocellular carcinoma (HCC). Patients' selection or approach was not randomized. Results The CLIP score LR OR 0.59 ± 0.75 0.86 1.04, respectively, (). operation time 156.3 308.2 190.9 79.2 min groups, respectively. necessity blood transfusion found in 8 (6.9%) 106 (50.9%) groups. resumed...
The PM2.5 (particulate matter with a diameter of less than 2.5 μm) trends during the period 2013–2015, in 13 cities over Beijing–Tianjin–Hebei region, and their causes, were investigated using observations at 75 stations regional air quality model. It was found that annual this region experienced significant decrease 2014 2015, compared 2013. 2015 almost met target on 13th Five-Year Plan (2012–2017).
