Analyzing determinants of biological age through systematic review of prediction models

Chronological age is an inadequate indicator of an individual’s functional state, and a large number of models now estimate biological age from biological and clinical measurements. These models differ widely in the variables they use, and no synthesis exists of which variables r...

The Structure-Observer Interpretation Hypothesis

Even when the same object or structure is given, the interpretation that arises from it is not necessarily determined by the structure alone. This paper proposes that Interpretation depends on the Observer Intelligence that observes a Structure, and further that what an Observer...

The Abstraction Fixation Mismatch Hypothesis

Humans and artificial systems routinely use abstractions to make complex relations tractable. Trees organize relations spatially through hierarchy; pipelines organize processes temporally through sequence. Such structures can function as optional aids for representation, explanat...

Moral distress and healthcare resource cutbacks: Leaders’ and professionals’ experiences

Background Healthcare resource cutbacks create organizational conditions that may constrain moral agency and contribute to moral distress, yet little is known about how leaders and healthcare professionals experience these ethical challenges. Aim The aim of this study was to expl...

Physics-guided residual inverse-transition modeling for continuum robots with simulation and ordered experimental evaluation

Abstract This study distinguishes two levels that were conflated in the original submission: a tendon-driven mechanical dynamics model used only in simulation, and an ordered one-step inverse-transition estimator used for the recorded experiment. The experimental estimator does n...

The effect of Coulomb interactions of thermoelectric characteristics of Marcus molecular junctions

We present a theoretical study focused on the influence of Coulomb interactions on thermoelectric properties of molecular junctions assuming that electron transport is strongly affected by thermalized phonon modes in the molecular ambient. It is shown that the combined effect of...

Monitoring Liquid Concentration Changes in Nanofluidic Channels Using Cross-Grating Wavefront Microscopy

Abstract Optical microscopy that employs intensity measurements of scattered, transmitted, or emitted light is critical to study micro- and nanofluidic systems widely used in, e.g., biology, chemistry, and materials science. Since such fluidic systems often are transparent, simpl...

Blast.jl: Differentiable Non-Limber Power Spectra for Joint Clustering, Shear, and CMB lensing Analyses

Upcoming large-scale structure surveys require accurate theoretical predictions for angular power spectra on the largest angular scales, where the commonly used Limber approximation breaks down and multiple relativistic and observational effects become relevant. At the same time,...

OxyContin's Reformulation and Substance Use Disorder Treatment: Evidence from Admissions and Facilities

I examine how the substance use disorder treatment sector responded to the abuse-deterrent reformulation of OxyContin, which contributed to a shift from prescription opioid misuse to heroin and synthetic opioids in the 2010s. States with higher pre-reformulation rates of OxyConti...

Element interaction manifolds for comparative analysis of geometric representations in protein-ligand recognition

Code and reproducibility materials accompanying the manuscript "Element Interaction Manifolds for Comparative Analysis of Geometric Representations in Protein–Ligand Recognition." The archive contains the implementations used for the principal geometric representations evaluated...

Comparative properties of sodium sulfate-activated lime–pozzolan cements incorporating rice husk ash or corn cob ash

Growing environmental concerns associated with ordinary Portland cement (OPC) production have intensified the search for sustainable, low-carbon cementitious materials. Rice husk ash (RHA) and corn cob ash (CCA) are promising agricultural-waste-derived pozzolans for lime-based bi...

Energy transfer and scale organisation in dense canopy turbulence

This study identifies the scale-dependent processes that sustain turbulence in dense submerged canopy flows. Using a scale-resolved energy budget, we determine where in space and at which scales production, pressure–strain redistribution and inter-scale transfer predominantly occ...

Systems serology identifies differential pan-viral seroreactivity profiles associated with healthy aging and cancer

Abstract A viral exposure signature (VES) has previously been shown to predict the development of hepatocellular carcinoma (HCC) in at-risk individuals through comprehensive serological profiling using the VirScan platform. Whether cumulative antimicrobial immune histories are as...

Polymer-Linked Nanoparticle Networks Running on Heat Can Act as Computing Devices

Abstract Developing physical neural network (PNN) hardwares is important to next-generation artificial intelligence systems. Phononic devices─using heat current to encode and process information─is one of the solutions to neuromorphic computing. In this work, we backmap an artifi...

Kerr-Newman and genuine Kerr black holes in the Bertotti-Robinson magnetic field

We present a spacetime that describes a rotating and charged black hole immersed in an external magnetic field. This exact solution to the Einstein-Maxwell equations has a surprisingly simple form which reduces to standard Kerr-Newman metric, and to the uniform Bertotti-Robinson...

Deterministic generation and distribution of genuine multipartite entanglement in macroscopic acoustic resonators

Generating complex multimode entanglement is a central goal of quantum information science. However, scalable creation of genuine multipartite entanglement is challenging as it requires excellent control and efficient state verification. We report the generation and transfer of g...

Artificial intelligence ethical awareness and academic integrity among medical students at the University of Khartoum: a cross-sectional study

Integration of artificial intelligence in healthcare and medical education implies significant opportunities along with significant ethical challenges. Despite the substantial medical student uptake of artificial intelligence globally, little comprehensive assessments of ethical...

pynucastro 3: A community library for nuclear astrophysics

We describe the latest release of pynucastro: a community python library for nuclear astrophysics. The goal of the pynucastro project is to build the tools needed to interactively explore nuclear properties, reaction rates, and networks, and to export these networks to a variety...

The Evolution of Low-ionization Electron Densities in Galaxies across Cosmic Epochs

Abstract We investigate the low-ionization electron density in the interstellar medium (ISM) of galaxies across 0 < z < 8, derived with the [O ii ] λλ 3727, 3730 and [S ii ] λλ 6718, 6733 doublets, using both deep JWST/NIRCam/grism and NIRSpec/MSA spectroscopy. Along with ancilla...

LIGO Detector Characterization in the Second and Third Parts of the Fourth Observing Run

Abstract LIGO detector characterization efforts enabled the confident detection of gravitational waves from hundreds of compact binary coalescences during the fourth observing run. Reliable production of high quality detector data and rapid noise mitigation efforts allow the extr...
