Unique geochemical conditions and microbial composition of pockmark sediments in a brackish-water eutrophic continental shelf sea

Abstract In marine pockmarks, interactions between outflowing gas, infiltrating freshwater, and increased input of organic matter (OM) affect the supply and utilization of particular electron acceptors required primarily for OM mineralization. Consequently, geochemical processes...

Enabling stable preservation of ML algorithms in high-energy physics with petrifyML

Machine learning (ML) in high-energy physics (HEP) has moved in the LHC era from an internal detail of experiment software, to an unavoidable public component of many physics data analyses. Scientific reproducibility thus requires that it be possible to accurately and stably pres...

Entropy maximization and weak Gibbsianity of quasi-free fermionic states

Abstract In their 1972 study of approach to equilibrium, Lanford and Robinson showed that gauge-invariant quasi-free states of lattice fermions maximize entropy among all translation-invariant states with a fixed two-point function and suggested that the maximizer is unique. In s...

Methodological Approaches to Bioavailability of Oral Creatine in Randomized Controlled Trials: A Meta-Research Study

Background: Creatine is one of the most widely used dietary supplements for enhancing physical performance and is increasingly investigated for a range of health-related applications. Although creatine monohydrate is the most commonly used formulation, concerns have been raised r...

Current Trends and Advances in Research on Rare Earth Elements (REEs) in Groundwater: A 2010–2025 Bibliometric Analysis

Abstract Rare earth elements (REEs) are becoming increasingly important in the global economy and environmental research, especially in studies of water circulation and water chemistry. The paper presents the results of a bibliometric analysis of studies on the presence of REEs i...

Saturable absorption in NV-doped diamond studied by femtosecond Z-scan

Nonlinear optical absorption in commercially available diamond crystals containing nitrogen-vacancy (NV) centers is investigated using femtosecond open-aperture Z-scan measurements at a wavelength of 1032 nm. Experiments were performed on a high-purity electronic-grade diamond an...

Boost-invariant Perfect Fermi–Dirac Spin Hydrodynamics

We analyze the effect of using the Fermi–Dirac statistics, rather than its Boltzmann approximation, in numerical simulations of perfect spin hydrodynamics of particles with spin \(1/2\). The system considered is boost invariant, transversely homogeneous, with corrections to the b...

Geriatric nutritional risk index as a potential prognostic indicator in pancreatic cancer: evidence from a systematic review and meta-analysis

Malnutrition is highly prevalent among patients with pancreatic cancer and has a substantial impact on prognosis, treatment tolerability, and quality of life. However, the prognostic significance of the Geriatric Nutritional Risk Index (GNRI), a simple and objective tool for asse...

Illness Acceptance Among Adults with Melanoma: A Prospective Observational Cross-Sectional Study

Introduction: Melanoma is a chronic disease that significantly affects patients’ daily functioning and emotional well-being. Beyond its somatic burden, it often leads to substantial changes in quality of life (QoL). This study aimed to assess illness acceptance among melanoma pat...

From ACR O‐RADS 2022 to Explainable Deep Learning

Objectives The 2022 update of the Ovarian‐Adnexal Reporting and Data System (O‐RADS) improves risk stratification of adnexal lesions; however, radiologist interpretation remains subject to inter‐observer variability and conservative diagnostic thresholds. Concurrently, deep learn...

Mixed electoral systems: The best of both worlds or the worst of both?

Abstract Mixed electoral systems combine majoritarian and proportional rules within a single institutional framework, promising what Shugart and Wattenberg (2001) called "the best of both worlds": local accountability alongside representational fairness. This article surveys the...

Vitamin K in photosynthetic organisms

Main conclusion Recently, great progress in vitamin K research in plants was made, especially on vitamin K epoxide reductase (VKOR) homolog, new functions of VK in plant plasma membrane and VK1 biosynthesis. Abstract Although vitamin K (VK) was discovered in the 1930s, only recen...

The Impact of Road Traffic Noise on Apartment Prices in Kraków: A Hedonic Analysis of the Primary and Secondary Markets

This study examines the effect of road traffic noise on apartment prices in Kraków, treated on an equal footing with the other price-forming attributes. The analysis draws on 6244 transactions from the primary and secondary markets concluded between January 2021 and June 2022. Mu...

Evolution of the Surface Composition of Graphene Oxide Films During Laser-Induced Reduction

Graphene oxide (GO) and reduced graphene oxide (rGO) are widely studied two-dimensional carbon nanomaterials for optoelectronic devices. Because the oxygen content and degree of reduction govern the electronic structure of GO-derived films, controlling the reduction process is es...

Effect of palatal shape on dental arch relationships in unilateral cleft lip, alveolus, and palate

INTRODUCTION: Palatoplasty is a critical surgery for restoring structure and function in patients with cleft palate, but surgical scarring is considered a major factor in maxillary growth deficiency and abnormal dental arch relationships. Palatal scars can significantly alter pal...

Saturated Partial Embeddings of Planar Graphs

ABSTRACT In this work, we study how far one can deviate from optimal behavior when embedding a planar graph. For a planar graph , we say that a plane subgraph is a plane‐saturated subgraph if adding any edge (possibly with new vertices) to would either violate planarity or make t...

Energy Intensity Mapping of Battery-Electric vs. Diesel Heavy Haulage in Surface Mining: The Interplay of Payload Dynamics and Ambient Temperature

Decarbonizing heavy-duty transport in the mining sector requires a deep understanding of the interplay between specific energy consumption, payload dynamics, and ambient thermal stressors. This study presents an integrated, physics-informed machine learning framework to compare t...

Methane Capture and Hydrogen Production from Coal Mine Methane: A Sustainable Path for Energy Transition

Methane emissions from coal mines pose significant environmental and operational challenges. Methane can be released from coal seams and surrounding rock layers as a result of mining operations. These emissions pose environmental risks and can lead to fire and explosion hazards....
