Effects of water intrusion on fracture characteristics of hard coal

Abstract Aquifer water can cause serious geological hazards by catastrophically rushing into underground space. The water seepage can increase the moisture content and pore pressure of coal/rock, which can change mechanical behaviour of coal/rock subject to tectonic and abutment...

Experimental study on tire rolling resistance under complex conditions with temperature, wear, camber, and sideslip angle impacts

Tire rolling resistance is a critical factor influencing vehicle fuel economy and the driving range of electric vehicles. Multiple independent influencing factors affect tire rolling resistance, making it difficult to analytically predict rolling resistance variations under vario...

Multi-omics and physiological analyses provide insights into the mechanism of Golgi manganese homeostasis in regulating the development of young tissues in rice

Manganese (Mn) is indispensable for numerous Golgi-resident enzymatic reactions, and disruption of its homeostasis severely impairs plant growth. However, the regulatory mechanisms through which Mn dysregulation affects these metabolic processes remain largely uncharacterized. In...

Three truncated supercongruences for an Apéry-like sequence

For G_n = sum_{k=0}^n 4^k binom(2n-2k,n-k)^2 binom(2k,k), this preprint proves all six cases of a conjecture of Z.-H. Sun concerning three truncated sums with denominators (-16)^n, 8^n, and 32^n modulo p^2. An exact finite-tail transformation reduces the problem to classical trun...

A formal-group proof of a conjecture of Z.-H. Sun for an Apéry-like sequence

Let G_n = sum_{k=0}^n 4^k binom(2n-2k,n-k)^2 binom(2k,k). This preprint proves a conjecture of Z.-H. Sun asserting a three-term congruence for G_{(mp^r-1)/2} when p is congruent to 1 modulo 4. After an integral strict change of parameter, the formal logarithm becomes the Eichler...

Lignin-Assisted Construction of Coal-Tar-Pitch-Derived N/S Co-doped Porous Carbon for Boosted Zinc Ion Storage

Abstract Zinc ion capacitors (ZICs) based on a carbon cathode represent new generation energy storage system, owing to outstanding safety, economic viability, and ecological sustainability. However, carbon-based cathodes suffer from limited charge storage. Thus, it is urgent to d...

A Cobalt Porphyrin Doubly Tethered with Piperazine Groups for Highly Selective Electrocatalytic Four‐Electron Oxygen Reduction Reaction in Acidic Aqueous Solution

Comprehensive Summary Selective electrocatalytic four‐electron (4e) oxygen reduction reaction (ORR) is required in many new energy conversion technologies. Although Co porphyrins are active for electrocatalytic ORR, their selectivity for the 4e ORR is usually poor. Herein, we rep...

Cusp-Catastrophe-Based Evaluation of Critical Rockbolt–Grout Interface Debonding Displacement in Fully Grouted Rockbolts under Pull-Out Loading

ABSTRACT For a fully grouted rockbolt (FGR) subjected to pull-out loading, local instability may occur at the rockbolt–grout (R-G) interface when the surrounding medium is sufficiently stiff and the bolt–grout bond governs load transfer. This study derives a theoretical estimate...

Handgrip Strength and Early Screening of Alzheimer’s Disease: Current Evidence and Emerging Role of Artificial Intelligence

Alzheimer’s disease (AD) is the most prevalent progressive neurodegenerative disorder in older adults, marked by insidious cognitive decline and gradual loss of functional independence. Growing evidence suggests that handgrip strength (HGS) assessment may provide a simple, noninv...
