The Sobolev inequalities along the Ricci-Bourguignon flow and applications

‎Consider a closed Riemannian manifold $M$ where the metrics $g(t)$ evolve by the Ricci-Bourguignon flow (RBF)‎.‎The paper first derives a Sobolev inequality along the RBF‎. ‎Then‎, ‎by applying this‎ ‎Sobolev inequality we obtain a linear parabolic estimate and an upper bound es...

Bridging the GapBetween Laboratory Catalyst Researchand Practical Water Electrolyzer Commercialization

Abstract Water electrolyzers are key technologies for enabling a carbon-neutral society by facilitating sustainable hydrogen production. Despite extensive efforts to develop highly active catalysts, a persistent gap remains between catalyst performance evaluated in rotating disk...

Quantitative MRI Susceptibility: Mapping of Transient Ischemic Attack—A Preliminary Study

A transient ischemic attack (TIA) is a transient episode of neurological dysfunction without evidence of acute infarct demarcation on neuroimaging. The radiographic features of TIAs are uncertain, as since there is currently no perfect imaging method with which to differentiate a...

The study examined Technological Infrastructure and economic sustainability of Small and Medium Enterprises in Ebonyi State. The specific objectives are to: Examine the relationship between internet connectivity and Operational efficiency; and evaluate the relationship between te...

Effective Judicial Protection in Property Tax Administration: Legal Certainty, Reasoned Decisions and Access to an Effective Remedy in Latvia

This independent legal study examines the requirements of legal certainty, reasoned administrative decision-making and effective judicial protection in the context of immovable property tax administration in Latvia. The analysis is based on a documented administrative matter conc...

Mitochondrial Dysfunction as a Central Hub of Aging: From Molecular Cascades to Inter-Organ Communication Networks

: Background: Mitochondrial dysfunction serves as a fundamental driver of the aging process, precipitating progressive functional decline through complex molecular cascades. Summary: This review elucidates the core mechanisms underpinning this dysfunction, including reactive oxyg...

CircRNA Profiling Identifies Candidates Associated with Abdominal Fat Deposition in Ducks

Excessive abdominal fat deposition reduces the meat yield and feed conversion efficiency of meat ducks. To identify circRNAs associated with this trait, this study performed circRNA sequencing on abdominal fat tissue from fat-type (HF) and lean-type (LF) Peking ducks. Among the 1...

Real‐Time Arbitrary Multi‐Bit Phase Manipulation Based on 2‐Bit Digital Spoof Surface Plasmon Polaritons with 360° Phase Coverage

ABSTRACT As a core enabling technology in modern information systems, digital phase manipulation is urgently required to deliver higher phase‐shifting accuracy and enable flexible adjustment of the modulation order. However, conventional digital phase shifters provide fixed phase...

Caracterização da paisagem sensorial dos cafés de origem brasileiros: sustentabilidade, recursos naturais e expressão territorial da qualidade

Produtos agroalimentares associados à origem têm sua qualidade e reputação construídas pela interação entre território, recursos naturais, práticas produtivas e processos de transformação, relação particularmente relevante para o café. Esta pesquisa investiga como sustentabilidad...

Plasmonic‐Based Negative Photoconductance Photodetectors for a New Optical Window

ABSTRACT In recent years, the short‐wave infrared (SWIR) region has been extended to 2 µm, opening new opportunities for optical windows and light detection and ranging (LiDAR) applications, particularly due to advantages such as eye safety and long‐range detection. In this study...

Development of a dimensionless thermal comfort index for metro systems: Empirical modeling and validation in Nanjing’s subway network

The thermal comfort in subway carriages directly affects passengers’ travel experience and health, while optimizing it enhances energy efficiency and reduces operational costs. The overarching goal of this research is to develop a novel, metro-specific thermal comfort index that...

Iron‐Sulfur Cluster Targeting: A Novel Perspective for Treating Alcohol‐Related Lipid Metabolic Diseases

ABSTRACT Iron–sulfur (Fe–S) clusters are pivotal molecular cofactors bridging inorganic chemistry and organic life processes, with their tightly regulated biosynthesis and function underpinning cellular metabolic homeostasis. Chronic alcohol‐induced metabolic stress impairs Fe–S...

Evaluating abuse of power in administrative decision-making: a psychological and technological analysis of public administration

This study examines abuse of power in public administration, the reasons for its persistence in its traditional form, and its adverse impact on the quality of administrative action and the credibility of the principle of legality. It also evaluates the adequacy of the traditional...

Pleistocene-Holocene imprint of soil pyrogenic carbon and reversed ages in soil and cave flowstone

Wildfire can significantly alter karst surface environments, yet its impact on cave systems and speleothem archives remains poorly understood. This study investigates the relationship between surface fire events and their imprint on inverted ages recorded in soil and flowstone in...

Rock Pillar Fracture-Induced Vibration Characteristics and Rock Burst Mechanism in Steeply Inclined Extra-Thick Coal Seam Group Mining

Clarifying the dynamic mechanism of rock pillar fracture and its rock burst-inducing mechanism is fundamental for the prevention and control of rock burst disasters in steeply inclined extra-thick coal seam groups. In this study, field monitoring, theoretical analysis, and numeri...

Association of pre-clinical depressive symptoms and its plasma metabolomic signature with Parkinson’s disease: a community-based longitudinal study

Abstract Accumulating evidence has suggested that depression is associated with an increased risk of Parkinson’s disease (PD), yet whether pre-clinical depressive symptoms in PD development and the potential mediating effects of metabolomic profiles remain unclear. We aimed to ex...

Development and evaluation of a German Paediatric Trigger Tool (PAED-TT-GER) for detecting adverse events in hospitalized children

Abstract Trigger tools (TTs) are highly recommended for structured detection of adverse events (AEs) through retrospective medical record review. However, available general tools require thorough adaptation to paediatric care and local documentation practices to ensure feasibilit...
