REV-based analysis of non-uniform heat transfer in irregular geometries of precast concrete sandwich wall panels

The thermal performance of buildings is largely determined by the weakest point in the envelope. Precast concrete sandwich wall panels are a new type of high-performance, multi-functional integrated component that has been widely adopted. However, local heat loss caused by metal...

Symmetry-Breaking Induced In Situ Electrochemical Oxidation of MnO to MnO2: A Space Group-Dependent Phase Evolution Mechanism

Abstract The electrochemical oxidation of MnO to MnO2 is a fundamental solid-state phase transition process, intimately associated with the evolution of crystal symmetry and space group. From the perspective of space group evolution, this study systematically reveals the transfor...

Robustness assessment of steel frame structures with novel T-stub connections under lateral impact

The extent to which novel T-stub connections (NTC) enhance the collapse resistance of steel frame structures under lateral impact remains unclear, and there is a lack of a systematic quantitative evaluation approach. To address this issue, a component-based modeling methodology w...

Cold plate with orifice-type manifolds and 3-pass channels for high temperature uniformity in battery packs

Flow maldistribution in liquid-cooled cold plates is often overlooked in battery thermal management system (BTMS) design, despite its critical influence on cell-to-cell temperature uniformity at the pack level. This study proposes a novel bottom-cooled liquid cold plate that inte...

Fractal Evolution of DIC-Derived Tensile Strain Localization in CNT–Recycled Steel Fiber Cementitious Composites Under Sulfate Dry–Wet Cycles

Sulfate dry–wet cycling can progressively alter the tensile damage mode and self-sensing behavior of conductive fiber-reinforced cementitious composites, whereas conventional strength indices cannot fully describe the spatial organization of damage. In this study, nine carbon nan...

Optimal exercise dose in adults with chronic low back pain disorders: systematic review with dose-response network meta-analysis

Objective To quantify exercise dose-response relationships and estimate the optimal dose in adults with chronic low back pain disorders (CLBDs). Design Systematic review with random-effects model-based (non-linear) dose-response network meta-analysis. Risk of bias was assessed wi...

One Stone for Three Birds: Synergistic Preparation of Nitrogen-Enriched Biochar, High-Quality Bio-Oil, and Syngas via Pyrolysis of Waste Chinese Medicine Residues

A Doppler-Aware RSRP Input Calibration Method for Handover in High-Speed Railway 5G-R

Short-term fluctuations in reference signal received power (RSRP) can repeatedly reset the time-to-trigger (TTT) timer and spatially disperse Event A3 handover triggers in high-speed railway 5G-R systems. This study presents a synchronization-aware, physically bounded calibration...

Evolutionary resilience enhancement of public facility maintenance systems in residential communities

Purpose This paper aims to examine the mechanisms and pathways for enhancing the evolutionary resilience of public facility maintenance systems in residential communities. The effective operation of public facilities in residential communities is an important indicator of the man...

Effects of optimized lignocellulosic pretreatment derivatives on hydrolysis efficiency and codigestion performance of corn straw with food waste

Corn straw is a typical lignocellulosic biomass, and its anaerobic conversion is generally limited by the hydrolysis limitation. Ozone pretreatment can effectively improve the biodegradability of straw; however, its key process parameters have not been systematically optimized or...

Experimental Investigation and Response Surface Optimization of Fiber-Reinforced Polymer Concrete for Mining Roadway Support

The escalating intensity and depth of coal mining operations have exacerbated underground strata pressure, resulting in fracture-induced air leakage channels that heighten risks of coal spontaneous combustion and gas explosions. These challenges necessitate enhanced flexibility a...

Combined regulation of oxidized pyrite flotation by sodium sulfide and malic acid: Experimental investigation and DFT calculations

Surface oxidation of pyrite (FeS 2 ) during flotation produces hydrophilic Fe(III)-bearing species, substantially decreasing its floatability. In this study, a combined sodium sulfide (Na 2 S)-malic acid regulation system was developed to improve the flotation response of oxidize...
