Determination of energy storage scheme for hybrid photovoltaic-assisted heating system in residential buildings

Photovoltaic (PV)-assisted heating systems can meet residential electrical and thermal demands using heat storage (HS) or Li-ion battery (LB) storage. However, identifying the appropriate storage scheme under different solar-resource and building-load conditions remains challengi...

Mining-Sequence Effects on Slope Deformation and Stress Redistribution During Cemented Backfill Mining of Multiple Extra-Thick Coal Seams Beneath an Open-Pit Highwall

Cemented backfill mining has become an effective approach for recovering coal resources beneath open-pit highwalls while maintaining slope stability. However, the repeated extraction of multiple extra-thick coal seams induces complex overburden responses, and the effects of minin...

Multimodal Transformer Integrating CT and Pathology for Postoperative Risk Stratification in Stage I Non–Small Cell Lung Cancer

A biologically interpretable multimodal artificial intelligence framework outperformed guideline-based postoperative risk stratification for stage I non–small cell lung cancer and identified patients who would benefit from adjuvant therapy.

High‐Rate Magnesium‐Ion Batteries Enabled by Boron‐Doped Bismuth Anodes

Large volume expansion upon (de)alloying faced by bismuth anodes always leads to severe capacity loss and poor durability for magnesium‐ion batteries. This failure mode becomes particularly pronounced under high current‐density impact, where the sluggish electron transport and io...

Linguistic complexity and writing proficiency in assessing L2 Spanish writing

Abstract Although linguistic complexity is widely used to assess second language (L2) writing proficiency, the linguistic correlates of L2 Spanish writing proficiency remain relatively underexplored. This study addresses this gap by examining how selected lexical, syntactic, and...

A multi-mode active frequency support strategy for a grid-friendly integrated PV-ES system

The integration of photovoltaic (PV) and energy storage (ES) is an effective solution to mitigate PV output fluctuations and enhance solar energy utilization. However, existing PV-ES coordination schemes are often limited by insufficient consideration of source-side support capab...

Regenerating High-Performance Lithium Iron Phosphate through Establishing a Stable Structure via Designing a Reaction Path with Easy-Transformed Intermediates

Abstract Regenerating lithium iron phosphate (LFP) from recovered lithium carbonate and iron phosphate by conventional hydrometallurgy process is challenged by high wastewater treatment cost and the unsatisfying performance of regenerated LFPs. Herein, a nanoscale LFP with enhanc...

Preclinical characterization and first-in-human phase I dose-escalation results with JYB1907, a novel anti-GARP-TGF-β1 complex monoclonal antibody in patients with advanced solid tumors

Transforming growth factor-β1 (TGF-β1) promotes immunosuppression in the tumor microenvironment via the GARP-latent TGF-β1 complex on regulatory T cells. JYB1907 is a humanized IgG4 monoclonal antibody targeting this complex. Preclinically, JYB1907 bound GARP-latent TGF-β1 comple...

Conditional diffusion for single-cell Hi-C data imputation and enhancement with scHiC-Diff

Single-cell high-throughput chromosome conformation capture (scHi-C) enables the analysis of cell-to-cell variability in three-dimensional (3D) genome organization, but its utility is severely limited by pervasive technical dropouts, leading to extremely sparse contact maps. Accu...

Post-collisional potassic magmatism with elevated Rb concentrations in the Muria back-arc, Central Java: constraints from Rb-Hf-Ta systematics and mantle source interactions

The Muria volcanic complex (MVC), located in the rear-arc of Central Java, Indonesia, represents an unusual potassic-alkaline magmatic system within an otherwise calc-alkaline subduction-dominated arc. This study integrates compiled geochemical datasets, including major oxides, t...

Dendrobine Attenuates Cisplatin-Induced Acute Kidney Injury with KEAP1–NRF2 Activation and Reduced Ferroptosis-Associated Stress

Acute kidney injury (AKI) lacks effective pharmacological therapies, and ferroptosis-associated lipid peroxidation contributes to renal tubular injury. Here, we investigated the protective effects of dendrobine against AKI and its mechanisms. Dendrobine was evaluated in murine ci...

Associations between non-insulin-based insulin resistance surrogates and pulmonary hypertension due to left heart failure: a multicenter cohort study

Abstract Background Insulin resistance (IR) has been reported to have a close relationship with the development and adverse outcomes of various cardiovascular disorders, while its association with pulmonary hypertension due to left heart failure (PH-HF) remains to be elucidated....

Transient flash-temperature prediction using asperity microcontact pressure for rough-textured gear-tooth surfaces under mixed lubrication

Localized frictional heating at rough gear interfaces is strongly influenced by transient heat generation at discrete asperity contacts, whereas conventional flash-temperature methods represent the contact using an equivalent macroscopic heat source. This study develops an asperi...

Modulating liquid metal flow by IN718 addition to improve surface quality in laser direct metal deposition of SS 316L

The surface quality of cladding layer (CL) in laser direct metal deposition (LDMD) is strongly related to liquid metal flow. Improving the surface quality by modulating liquid metal flow is an effective strategy. Hence, a three-dimensional thermo-fluid dynamic model is establishe...

Stable truncating mutations in plakophilin-2 induce arrhythmogenic cardiomyopathy-like phenotypes in adult zebrafish

Arrhythmogenic cardiomyopathy (ACM) is an inherited cardiac disorder characterized by arrhythmias and fibrofatty myocardial remodeling, often leading to heart failure and sudden cardiac death. Mutations in plakophilin-2 ( PKP2 ) represent the most prevalent genetic cause of ACM....

Advances in Aerobic Exercise for Pulmonary Arterial Hypertension: Mechanisms of Action and Clinical Insights
