Abstract Aims The combination of haemoglobin, albumin, lymphocytes, and platelets (HALP) is a new metric used to assess patient prognosis in many diseases. This study aimed the relationship between HALP short‐ long‐term mortality patients with heart failure. Methods results retrospective cohort included adult failure who were hospitalized 2019 2021. primary outcomes 1‐month 1‐year mortality. multivariable logistic regression analysis was evaluate association risk Stratified analyses...
Abstract Empirical Green's functions (EGFs) are widely applied to correct earthquake spectra for attenuation and other path effects in order estimate corner frequencies stress drops, but these source parameter estimates often exhibit poor agreement between different studies. We examine this issue by analyzing a compact cluster of over 3,000 aftershocks the 1992 Landers earthquake. apply compare two analysis modeling methods: (1) spectral decomposition global EGF fitting approach (2) more...
The topography evolution of the southeastern Tibetan Plateau provides a constraint for evaluating various geodynamic models plateau formation. We reconstruct Paleocene to Eocene paleoelevation Cenozoic Gonjo basin in Qiangtang terrane, using oxygen and carbon stable isotopic results from pedogenic carbonates lower Ranmugou Formation. Lithofacies associations indicate that Formation was deposited alluvial fan fluvial floodplain environments. U-Pb dating volcanics within middle constrains...
Abstract Quantifying the removal of co‐seismic landslide material after a large‐magnitude earthquake is central to our understanding geomorphic recovery from seismic events and topographic evolution tectonically active mountain ranges. In order gain more insight into fluvial erosion response landslides, we focus on sediment fluxes rivers flowing through rupture zone 2008 M w 7.9 Wenchuan in Longmen Shan eastern Tibetan Plateau. Over post‐seismic period 2008–2013, annually collected river...
Abstract Well‐constrained fault slip rates are important for understanding strain partitioning within a system and the associated seismic hazard. The Haiyuan is significant active strike‐slip in northeast margin of Tibetan Plateau with ongoing controversy over its late Pleistocene rate. Previous work by Lasserre et al. (1999) suggested rate 12 ± 4 mm/year, which higher than recent geodetically determined on adjacent sections. We reanalyze reevaluate benefiting from new high‐resolution...
River incision results from interactions among tectonics, climate change, and surface processes, yet the role of each process operating at different time scales remains poorly understood. In this study, we address issue by reconstructing late Quaternary spatiotemporal variation aggradation rates along Lancang (Upper Mekong River) in southeast Tibet. Our work combined field observations, topographic data analysis, optically stimulated luminescence (OSL) cosmogenic radionuclide (CRN) dating...
Reliable estimates of Quaternary or Cenozoic upper crustal shortening in the Longmen Shan fold-and-thrust belt are rare. In this paper, we report on our use high-resolution 2-D and 3-D seismic reflection profiles at various scales, together with borehole data, to investigate structural geometry piedmont. The results reveal a thrust system beneath Shan, termed range front system, which consists blind its upward splay faults. Moreover, these faults identified growth strata that provide an...
Abstract Geometrical complexities such as bends and branches are ubiquitous along strike‐slip faults. Understanding strain partitioning between the different fault strands sections is key to assessing kinematics evolution through time of a system related seismic hazards. The Haiyuan fault, one longest faults Tibetan Plateau, has developed multi‐stranded complex geometry Hasi Shan restraining bend. In this study, we quantified slip rate ∼50‐km‐long Zihong which poorly‐known southernmost...
Abstract Induced earthquakes are becoming a significant issue. Several destructive induced (Ms ≥5.0) have occurred in shale gas fields located at the southwestern Sichuan basin, China, recent years. Specifically, two moderate with magnitudes of Ms 5.4 (occurred on 8 September 2019) and 5.2 18 December exceeded largest earthquake ever recorded Weiyuan. It remains unclear which seismogenic faults were responsible for events due to insufficient knowledge subsurface structure contradictory...

Abstract The Longmen Shan range, located on the eastern margin of Tibetan Plateau, is characterized by steep topography and a shortening rate <3 mm/yr. This peculiar configuration source controversy questions about topographic evolution dynamics this orogenic plateau margin. Investigating variations in surface denudation over different spatial temporal scales important for better understanding evolution, but there still lack erosion‐rate data averaged millennial timescales along frontal...
Abstract The automatic phase‐picking detection of earthquakes is a challenge under the background big data and strong noise circumstances. short‐term average/long‐term average (STA/LTA) ratio widely used to detect earthquake due its simplicity robustness. However, STA/LTA‐based methods may not perform well with noisy data. Based on signal‐to‐noise‐ratio (SNR) concept, power/long‐term power (STP/LTP) method proposed. characteristic function thresholds STP/LTP are given physical meanings....
The 2021 Mw 7.4 Maduo (Madoi) earthquake that struck the northern Tibetan Plateau resulted in widespread coseismic deformation features, such as surface ruptures and soil liquefaction. By utilizing unmanned aerial vehicle (UAV) photogrammetry technology, we accurately recognize map 39,286 liquefaction sites within a 1.5 km wide zone along rupture. We then systematically analyze distribution characteristics possible influencing factors. density remains on higher level 250 m from rupture...
The simultaneous iterations reconstruction technique (SIRT) is one of several algorithms the ART family. It used widely in tomography because its convenience dealing with large sparse matrices. Its theoretical background and iteration model are discussed at beginning this paper. Then, implementation SIRT to reconstruct three-dimensional distribution water vapor by simulation discussed. results show that can function effectively tomography, obtain rapid convergence, be implemented more easily...
Elevated serum immunoglobulin G4 (IgG4) is one of the important features patients with IgG4-related diseases (IgG4-RD). But diagnosing these using IgG4 alone tricky because tests can sometimes give inaccurate results. Our research focused on studying ratio to two other substances, G (IgG) and G1 (IgG1), in blood. We hope this approach will lead more accurate diagnoses IgG4-RD.We conducted a study 68 diagnosed (IgG4-RD) 160 individuals suffering from autoimmune (AID) at our hospital between...
