Abstract Type 2 diabetes mellitus (T2DM) has evolved into a global public health crisis characterized by high prevalence, chronic progression, and multisystem complications, including cardiovascular, renal, hepatic, and bone metabolic disorders. Insulin resistance (IR) serves as...

Association of neoadjuvant subcutaneous trastuzumab with higher pathological complete response in HER2-positive breast cancer: a real-world doubly robust study

Randomized trials have demonstrated the non-inferiority of subcutaneous (SC) versus intravenous (IV) trastuzumab. Its association with pathological complete response (pCR) in routine neoadjuvant practice warrants further study. The ability of serial ultrasound measurements to dis...

Review on ammonia/coal co-combustion fundamental and technology in thermal power generation

Abstract Ammonia, as a carbon-free fuel, promises a significant cut of CO 2 emissions from power sectors, especially in coal-fired power plants. Direct combustion of ammonia in existing boiler systems is hindered owing to low flame temperature, decreased flame velocity, low react...

Transformer and self-supervised learning-based state-of-charge prediction method for lithium-ion batteries

Abstract The state-of-charge (SOC) estimation of lithium-ion batteries is essential for the performance, safety, and longevity of electric vehicles. While traditional physics-based models face difficulties in predicting SOC under complex conditions, data-driven methods demand lar...

GLI-AL: A Multi-Modal Glioma MRI Label Resource with Unified Anatomy-Lesion Labels

Existing BraTS-GLI datasets provide a widely used benchmark for adult glioma MRI segmentation, but their task definition focuses on tumor subregions and does not systematically represent coexisting white matter hyperintensities (WMH). In joint segmentation settings, such unlabele...

ABSTRACT Topological photonics has emerged as a versatile platform for exploring robust wave phenomena by translating concepts from topological band theory into optical systems. Early developments focused on photonic analogues of topological insulators, where protected edge state...

Integrated thermal management of high-power solid-state lasers: heat generation, cooling architectures, interfaces, and thermo-optic performance

Thermal effects critically limit power scaling, beam-quality preservation, and operational stability in high-power solid-state lasers. As heat-flux densities rise, thermal management has moved beyond external cooling enhancement toward coordinated control of heat generation, heat...

Compliance or Cooperation? Partner Reactions to Contractual Governance in Buyer–Seller Relationships

Purpose This study aims to investigate how the safeguard and coordination functions of contractual enforcement influence buyers’ compliance and cooperation in buyer–seller relationships. It also examines how relationship tenure moderates the effects of these contractual enforceme...

Structural optimization of vapor-cooled shields using a three-dimensional heat transfer model for enhancing storage efficiency

The intrinsically low boiling point and small latent heat of vaporization of liquid hydrogen make it highly susceptible to evaporation during storage and transportation. Given the high energy cost of hydrogen production, minimizing evaporation losses is crucial to avoid substanti...
