Differentiating W and W–Sb mineralization in the Xuefeng Uplift, South China: An integrated study of scheelite geochemistry

The Xuefeng Uplift Belt in Hunan Province, South China, represents a transitional metallogenic domain between the Nanling Region and Jiangnan Orogen, hosting a series of Au–Sb–W polymetallic deposits formed under contrasting metamorphic and magmatic-hydrothermal regimes. To eluci...

Zircon U-Pb Geochronology and Mineral Chemistry of Xinhe Mafic Rocks: Petrological Constraints on Water Heterogeneity in the Emeishan Large Igneous Province

The debate of hydrous and anhydrous mafic magmatism in the Emeishan large igneous province (ELIP) requires more robust petrological and mineralogical evidence. This paper reports zircon U–Pb ages, clinopyroxene and hornblende major element compositions, whole-rock geochemical and...

Evolution mechanism of damage locations in drift region of SiC MOSFETs under heavy ion irradiation

This paper investigates the evolution mechanism of severe thermal damage locations in the drift region of the SiC MOSFETs under different applied drain voltages (VDS(irra)) during heavy ion irradiation using 587 MeV 36Kr ions. It is interesting to find from the post-irradiation b...

Reading 905 nm UART Laser Rangefinder Modules: Two Frame Families, Per-Model Units, and Manual Inconsistencies

Technical note by the module manufacturer (ERDI Technology (Chengdu), https://erdilrf.com/). Summarises the two UART wire-protocol families of ERDI 905 nm laser rangefinder modules (8-byte 55 AA command/response; free-running 5C frames), the per-model unit differences (centimetre...

Seismo-ripples

Earthquake prediction has long been considered one of the greatest challenges in the global scientific community due to the complex and uncertain nature of seismogenic processes, along with the prevailing consensus that earthquakes are inherently unpredictable. Here, we present a...

Victims’ relational work in online investment fraud

Victims’ participation in online investment frauds is not just justified by egoist desire or greed, but also changing relational frames under uncertainty and ambiguity. Drawing on the concept of relational work from economic sociology, this paper examines how victims of the ‘Chin...

Hydration sequence controls polymer-induced water repellency and hydraulic response in illite-rich clay

Although geomaterial hydrophobisation is well established, the role of hydration sequence in polymer-induced water repellency of illite-rich clay remains insufficiently constrained. A butyl-acetate-assisted polydimethylsiloxane (PDMS) formulation was applied to a multi-mineral il...

Molecular Confinement Engineering of Mn(II) Halide Scintillators for High-Resolution X-ray Imaging and Three-Dimensional Computed Tomography

Abstract Metal halide scintillators hold great promise for next-generation X-ray imaging, yet manganese(II)-based halide scintillators suffer from structural instability and thermally activated nonradiative losses arising from their soft lattice nature. Here, we develop a molecul...

Hierarchy-dependent shear resistance and load sharing in root system reinforced soil: Insights from 3D DEM simulations

This paper investigates the shear reinforcement mechanisms of hierarchical tree root systems using three-dimensional discrete element method (DEM) simulations. A hierarchical root model based on Bischofia javanica was developed, explicitly representing taproots, lateral roots, an...

Hydrothermal carbonization process waters: Linking composition with recovery, recirculation, and treatment routes

Hydrothermal carbonization process waters (HTC PWs) contain feedstock-derived carbon, nutrients, dissolved ions, and potentially recoverable organics, but also inhibitory and poorly biodegradable fractions. This review links feedstock composition and HTC conditions to PW composit...

A retrospective cohort study of the association between triglyceride-glucose index and its derived indicators and all-cause mortality among community-dwelling adults with a history of stroke

Abstract Objective As a novel marker of insulin resistance, the triglyceride-glucose (TyG) index has been documented to correlate with mortality in coronary artery disease and heart failure. In recent years, growing attention has been paid to the relationship between the TyG inde...

Orbital Coupling‐Induced Quasi‐Covalent Interaction in Nd‐Doped L1 2 ‐Pt 3 Co Intermetallic Catalysts for Durable Fuel Cells

ABSTRACT Platinum remains the benchmark catalyst for proton exchange membrane fuel cells, but its long‐term durability and tolerance toward CO impurities are still insufficient for demanding practical operation. Here, we propose a novel perspective to address the degradation and...

Greening thy neighbor: The impact of cross-border high-speed rail network positions on transboundary air pollution in China

Existing studies mainly examine the environmental effects of high-speed rail (HSR) at the regional level, with limited attention to administrative border areas where pollution externalities interact with jurisdictional fragmentation. This study introduces the concept of cross-bor...

PGFT-IGR: position-guided feature transformation for incremental gait recognition

Real-world gait recognition systems must continuously enroll new users while coping with evolving gait patterns over time. Conventional model training methods cannot adapt to such ongoing changes, leading to catastrophic forgetting and performance degradation. Moreover, in practi...

OIB‐Type Garnet Amphibolites From the Xuerongzangbu Area, Central Lhasa Terrane, Tibet: Implications for Songduo Paleo‐Tethys Ocean Evolution and Permian Mantle Activity Along North Gondwana

Abstract Whether the Songduo metamorphic belt represents an in situ Paleo‐Tethyan suture within the Lhasa Terrane or far‐traveled allochthonous high‐pressure slices, and how Permian mantle activity along the North Gondwana margin relates to subsequent Tethyan evolution, remain ce...

The Size of Greater India: Estimates by Comparing the Apparent Polar Wander Paths of the Tethyan Himalaya and the Indian Craton

Abstract The northern extent of Greater India is a critical, yet highly debated, parameter for reconstructing the India‐Asia collision. Previous paleomagnetic estimates, including the fill‐the‐gap and fixed great circle approaches, yield widely varying results, spanning from ∼200...

Dual‐Channel Event‐Triggered Model‐Free Adaptive Control for Discrete‐time Nonlinear Networked Control Systems

ABSTRACT In this article, a novel dual‐channel event‐triggered model‐free adaptive control (DCET‐MFAC) algorithm is investigated to solve the tracking control problem for nonlinear networked control systems (NCSs). Two independent event‐triggered mechanisms (ETMs) are designed wi...
