Soil CH4 and CO2 emissions mediated by water and afforestation in Horqin Sandy Land

Ecological restoration in arid and semi-arid regions plays a vital role in maintaining regional carbon balance under global change. Although water management and vegetation composition regulate soil carbon cycling, their combined effects on greenhouse gas source/sink dynamics in...

Evaluation of turbulent flux parameterizations over a continental glacier on the Tibetan Plateau

A lack of observations of turbulent fluxes over continental glaciers limits our understanding of the mechanisms that control glacier variations and associated water resource changes across the Tibetan Plateau (TP). Here, we present the first comprehensive analysis of turbulent fl...

Who will replace their phones? An explainable machine learning approach using large-scale telecom behavioral data

Purpose Rapid technological innovation has accelerated the diffusion of mobile phones and communication networks, making phone replacement an important consumer behavior in the telecommunications market. However, limited research has examined the determinants of phone replacement...

Exploring calibration-free luminescence thermometry with Mn 4+ anti-Stokes/Stokes emission

Mn 4+ -activated phosphors offer a unique possibility of calibration-free primary luminescence thermometry using the ratio of anti-Stokes to Stokes (AS/S) vibronic emission lines of the 2 E → 4 A 2 transition. Previous work used the AS/S emission of Mn 4+ for thermometry but alwa...

A Modular Peptide Strategy for Targeted Lysosomal Degradation of TGF-βR1

Abstract Direct depletion of TGF-βR1 may provide more durable suppression of profibrotic signaling than occupancy-driven inhibition, but compact lysosome-directed degraders remain underdeveloped. Here, we report a peptide-based strategy for lysosomal degradation of TGF-βR1 by re-...

Warm-sector heavy rainfall over the eastern China plains: identification, characteristics, and precursor dynamic signals

Abstract. Warm-sector heavy rainfall (WSHR) features small spatial scales, posing critical forecast challenges, while its fractional contribution to regional heavy rainfall and its short-term precursors remain poorly quantified. Drawing on 2021–2025 warm-season (June–September) o...

Contrasting climatic controls on bimodal growth of Pinus elliottii plantations between northern and southern subtropical zones

Subtropical plantation forests play a crucial role in the global carbon cycle, yet intensifying global warming may exert profound impact on tree growth and forest carbon uptake. Pinus elliottii Engelm. is a widely planted and representative plantation species in subtropical regio...

Modular Photocatalytic Three‐Component Gem ‐Difluoroalkylative Pyridylation of Alkenes via Pyridylphosphonium Salts

The difunctionalization of alkenes enables the efficient and simultaneous construction of two chemical bonds. However, methods for the simultaneous introduction of both a pyridine ring and a difluoromethyl group into alkene molecules remain scarce. Here, we report a strategy for...

Prototype-Guided Test-Time Adaptation for Real-Time EMG-Based Gesture Recognition

Surface electromyography (sEMG) signals facilitate intuitive human-machine interaction and are widely employed in applications such as prosthetics and rehabilitation. However, sEMG signal distributions are highly sensitive to variations in electrode placement, user physiology, an...

Trace Bifunctional Diboron Additive Enables Robust CEI/SEI Interphases for Long-Cycling 4.5 V Li||NCM811 Batteries

Abstract Developing efficient, low-cost, multifunctional additives that require small amounts and can simultaneously protect both the cathode and anode remains a major challenge for the practical application of lithium batteries. Herein, bis(2,4-dimethylpentane-2,4-glycolato)dibo...

Existence and Decay Estimates of Minimizers for the p -Laplacian Schrödinger Energy Functional with Hardy Potential and Sobolev Critical Growth

In this paper, we discuss the following nonlinear p -Laplacian problems with a Hardy term and Sobolev critical growth: { − Δ p u − μ | x | p | u | p − 2 u + λ | u | p − 2 u = | u | p * − 2 u + κ | u | q − 2 u , x ∈ R N ∖ { 0 } , ∫ R N | u | p d x = c , where N ≥ 2 , 1 < p < N , c...

Ultra Log-Concavity and Real-Rootedness of Dependence Polynomials

For some positive integer $m$, a real polynomial $P(x)=\sum\limits_{k=0}^ma_kx^k$ with $a_k\geqslant 0$ is called {log-concave} (resp. ultra log-concave) if $a_k^2\geqslant a_{k-1}a_{k+1}$ (resp. $a_k^2\geqslant \left(1+\frac{1}{k}\right)\left(1+\frac{1}{m-k}\right)\cdot$ $a_{k-1...

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...

Patch fragmentation accelerates alpine meadow degradation through altering soil water migration

The bidirectional coupling of hydrological and ecological processes is pivotal for maintaining ecosystem stability. Fragmented patch patterns are widespread in degraded alpine meadows worldwide, redistributing soil hydrothermal resources and potentially exacerbating ecosystem deg...
