A 4200-hour HyperFlash and ÉCLAT campaign on the hyperactive FRB 20240114A: constraining energetics with the most brilliant bursts

Abstract Hyperactive repeaters provide a unique window into the evolving environments and energy budgets of fast radio burst (FRB) sources, though they may not be representative of the FRB population in general. High-cadence observations are key to capturing the rarest and most e...

Oxidative Stress Biomarkers in Oncology: Biological Mechanisms, Clinical Utility, and Organizational Considerations

Oxidative stress is a fundamental driver of carcinogenesis and tumor progression, arising from an imbalance between reactive oxygen or nitrogen species and antioxidant defense mechanisms. This redox disruption contributes to genomic instability, metabolic reprogramming, inflammat...

The Tenocyte from Atom to Cell: A Critical Multiscale Synthesis Linking Collagen Chemistry, Tissue Mechanics, Cell Mechanobiology and Mathematical Modelling

The tenocyte builds, maintains, senses and degrades one of the most mechanically demanding extracellular matrices in vertebrates, yet the chemical, physical, biological and mathematical descriptions of this system have developed in largely separate literatures. This review examin...

Celastrol and Its Derivatives in Breast, Ovarian, and Cervical Cancer: Molecular Targets, Signalling Networks, and Nanocarrier-Based Delivery

Celastrol, a quinone methide pentacyclic triterpenoid obtained mainly from the roots of Tripterygium wilfordii Hook. f., forms covalent, often reversible, adducts with cysteine thiols in regulatory proteins, which underlies its multi-targeted action. This review summarises the pr...

Beyond Histocompatibility: Donor Tissue Immune States and Their Role in Heart Transplantation

Heart transplantation transfers not only donor alloantigens and functional myocardium but also a pre-existing tissue environment shaped by resident immune, vascular, stromal, and parenchymal populations. This review examines the hypothesis that the biological state of donor tissu...

Beam-offset thermoreflectance with Bayesian optimization to measure the anisotropic thermal properties of semiconductor superlattices

The directional nature of heat conduction in semiconductor superlattices—marked by significant differences between in-plane and cross-plane pathways—poses substantial challenges for precise thermal property assessment. Conventional frequency-domain thermoreflectance (FDTR) techni...

Institutional availability, training resources, and supervised participation in robot-assisted surgery among Polish urology residents: a nationwide survey

Robot-assisted surgery (RAS) has expanded rapidly in Poland, but its integration into resident education remains uncertain. In a nationwide anonymous 35-question survey sent to 390 Polish urology residents, 156 completed it (40.0%). Among respondents, 110 (70.5%) reported RAS ava...

Organ specific chrysanthemum biochar for circular waste reuse and sustainable plant production

Abstract Biochar (BC), a low-cost, carbon-rich material produced from a wide variety of biomass sources, is gaining increasing attention in horticultural practice. There is little research on the use of chrysanthemum residues in BC production, especially in the circular productio...

Advances in Sensing, Control and Path Planning for Robotic Systems

Robotic systems are increasingly expected to operate autonomously, safely, and efficiently in dynamic and uncertain environments [...]

Microbiological Risks in Organic Farming: Implications for Food Safety, Farmers’ Health and Agroecosystem Functioning

Environmental microbiology provides essential tools for understanding and managing biological risks in sustainable agricultural systems. Organic farming, which prioritises closed nutrient cycles, soil biological activity and reduced reliance on synthetic inputs, exemplifies the p...

Accurate starting points for one-shot G0W0 and Bethe–Salpeter equation calculations via effective tuning of range-separated hybrid functionals

The accuracy of one-shot G0W0 and Bethe–Salpeter equation (BSE) calculations depends strongly on the underlying starting-point eigensystem, which is commonly obtained from a mean-field density-functional approximation. Range-separated hybrid (RSH) functionals provide a particular...

Micro-foundations of sustainability: entrepreneurial identity and interaction patterns in plant-based food microenterprises

Purpose The paper aims to identify how entrepreneurs’ identities intersect with interaction patterns to facilitate sustainability-driven activities in microenterprises. In addition, it proposes a typology of sustainable entrepreneurs, ranging from Mission-Embedded Activists to In...

Adaptive Approximations to the Exact-Exchange Optimized Effective Potential

This dataset contains the numerical data and figures supporting the manuscript “Adaptive Approximations to the Exact-Exchange Optimized Effective Potential.” The archive provides the data underlying the finite-basis exact-exchange optimized effective potential (OEPx) calculations...

Impact of R/NIR irradiation of blood on selected hemostatic parameters during and after cardiopulmonary bypass in pigs

Cardiopulmonary bypass (CPB) is associated with significant hemostatic disturbances. Red/near-infrared (R/NIR) light, also known as low-level light therapy (LLLT), may attenuate these effects. This study investigated the impact of R/NIR irradiation on selected hemostatic paramete...

Inverse limit method for generalized Bratteli diagrams and invariant measures

Generalized Bratteli diagrams with a countable set of vertices in every level are models for aperiodic Borel automorphisms. This paper is devoted to the description of all ergodic tail invariant probability measures on the path spaces of generalized Bratteli diagrams. Such measur...

The personalization–privacy paradox in social media advertising: a cross-national study of ad attitudes and eWOM

Purpose This study aims to explore how advertising personalization and perceived intrusiveness influence consumers' attitudes toward social media ads and their subsequent electronic word-of-mouth (eWOM) behaviors. Using the privacy calculus theory and the theory of planned behavi...

Alterations in 5hmC and TET2 expression in bladder cancer and their associations with clinicopathological features and patient outcome

Abstract Bladder cancer (BLCA) remains a major clinical challenge due to its high recurrence rate and the limited availability of reliable prognostic biomarkers. Since epigenetic dysregulation is a hallmark of urothelial carcinogenesis, we investigated the expression patterns, cl...

Serum GFAP and UCH-L1 in selected older emergency department patients: positivity beyond documented head injury

Abstract Background Older adults frequently present to emergency departments (EDs) after falls or suspected head injury, often with multimorbidity, cognitive impairment, and uncertain injury timing. Glial fibrillary acidic protein (GFAP) and ubiquitin C-terminal hydrolase L1 (UCH...

Plasma-Driven Carbon Mobilization Creates a Transient Near-Surface Carbonaceous Interphase for Selective CO2 Conversion into CO

Abstract Carbon beds enhance plasma-assisted CO2 conversion into resources, but are commonly treated as stationary reactant surfaces. Here, we show that nonthermal plasma (NTP) continuously mobilizes and reconstructs carbon, generating a transient near-surface carbonaceous interp...
