Gravitational constant as a conserved charge in black hole thermodynamics

Recent work has demonstrated that coupling constants in a given action can be promoted to the role of conserved charges. This is achieved by introducing pairs of field variables constructed from combinations of scalar and gauge fields. This framework naturally suggests that the g...

On three-body effects and nuclear fusion

Confined to small regions, quantum systems exhibit electronic and structural properties different from their free space behavior. In Coulomb 3-body problems, configurations of close proximity of identically charged particles are classically unstable. They however exist as excited...

Absolute continuity of Rosenblatt measures

In the article, we address the problem of absolute continuity of translated Rosenblatt measures on the path space. In [Čoupek, P., Kříž, P., Maslowski, B., Stoch. Proc. Appl. 179n (2025) art. no. 104499], it is shown that there is no probability measure that would be equivalent t...

Research on Key Technologies for CEPC Alignment

The Circular Electron Positron Collider (CEPC), with its unprecedented scale encompassing a circumference of 100 kilometers and stringent alignment accuracy requirements, presents exceptional challenges for accelerator alignment and installation. The primary objective of this stu...

Synthesis of (FeCoNiCuMn)S high-entropy sulfide nanorods and its enhanced oxygen evolution reaction performance

High-entropy sulfides (HESs) have emerged as promising electrocatalysts for the oxygen evolution reaction (OER) due to their unique compositional tunability and synergistic effects. In this work, we report the rational synthesis of (FeCoNiCuMn)S HES nanorods via a facile hydrothe...

Casimir Force in Spacetimes with Torsion

We compute the Casimir force between perfectly conducting parallel plates in a spacetime endowed with constant axial torsion. Working within an effective field theory framework where torsion couples to the electromagnetic sector via a gauge-invariant Chern–Simons-type interaction...

Thermodynamic Study of Galaxy Clusters by a Relativistically Corrected Newtonian Potential

We investigate the thermodynamic behavior of galaxy clusters by employing statistical mechanical techniques. The canonical partition function is derived under this modified potential, from which key thermodynamic quantities including entropy, enthalpy, specific heat, and chemical...

Off-Target Retinal Pigment Epithelium (RPE) Expression of Cre in the Rhodopsin-iCre75 Mouse Line

Purpose: Cre mouse lines are an important tool to manipulate gene expression in specific cell types and at distinct developmental timepoints. Overlooked and off-target expression of Cre is a common issue with transgenic Cre lines that has confounded the interpretation of many stu...

Nanoplastic detection and quantification in high-altitude glacial snow samples from Italy, Switzerland and France

Abstract Plastic pollution is an ever-growing concern around the globe, with current research portraying the presence of contaminants even in previously pristine regions. Especially small particles, micro- and nanoplastics, can be dispersed over long stretches by atmospheric tran...

Rényi Holographic Dark Energy-Inspired Model and Scalar Field Reconstruction in Bianchi Type III Space-Time

In this study, we consider a cosmological model based on Rényi holographic dark energy within the context of an anisotropic Bianchi type III space-time geometry. The dark energy density is taken as a modified function of the Hubble parameter, which enables us to express the Einst...

Molecular Dynamics and Mechanistic Insights into the Ligand-Induced Conformational Stabilization of STAT3 and TNF-α

The structural stabilization and conformational modulation of inflammatory targets such as TNF-α and STAT3 are of great significance in the discovery of novel anti-inflammatory agents and provide valuable insights into ligandprotein interaction mechanisms at the molecular level....
