Robust NbN‐on‐Si/SiGe Hybrid Microwave Quantum Circuits With Long‐Term Stability

ABSTRACT Large‐scale quantum computing requires superconducting microwave circuits that simultaneously exhibit ultra‐low loss, long‐term reliability, and scalable integration with semiconductor technologies. Achieving these capabilities within a CMOS‐compatible platform remains a...

Association between prophylactic hydrocortisone and focal intestinal perforations in preterm infants born before 28 weeks gestation: an observational propensity matched population study in England and Wales

Objective To examine the association between prophylactic hydrocortisone, given to prevent bronchopulmonary dysplasia, and the risk of focal intestinal perforation (FIP) in preterm infants. Design Retrospective cohort study using routinely-collected data from infants born between...

Evaluating Unsteady Forces in Turbulence-Modeled Flows from Vorticity and Reynolds Stress

Vortex force maps (VFMs) link vortical flow structures to aerodynamic forces through compact-domain integrals weighted by geometry-only Laplace potentials. Existing VFM demonstrations include inviscid, laminar, two-dimensional, and three-dimensional applications but cannot analyz...

COMPASS – An open-source software package for creating multi-level representative nested synthetic populations for small areas

Simulation models, such as agent-based or microsimulation models capturing urban contexts, increasingly draw on spatially explicit, attribute-rich synthetic population datasets as real-world data inputs. Despite their growing relevance, the creation of such datasets via simulated...

Tidal disruption of stellar binaries as a pathway to exotic transients

Abstract Tidal disruption event (TDE) progenitors are commonly modelled as single stars on parabolic orbits around a supermassive black hole (SMBH), yet observations reveal a richer diversity of dynamical pathways. We show that tidal separation of stellar binaries by a 106 M⊙ SMB...

Korean Space Collision Environment Assessment Framework Based on 3D-Cell Model

Abstract Space situational awareness (SSA) requires purpose-matched models across spatial, temporal, and fidelity scales. Building on our previously reported three-dimensional (3D) cell formulation and implementation, this study establishes a reproducible, resolution-aware, catal...

Mutual constraints on global aerosol composition from novel PACE data and ModelE

Abstract. Aerosol climate impacts remain uncertain, in part because global aerosol composition observations have been unavailable to constrain Earth System Models (ESMs). We present the first comparison of aerosol composition from the Plankton, Aerosol, Cloud, ocean Ecosystem (PA...

Trillion-scale integrated framework for high-throughput materials databases and seamless sharing

Abstract Artificial intelligence is accelerating materials discovery, yet for complex systems such as high-entropy alloys, exhaustive exploration of their immense composition spaces is computationally intractable. Here we propose an integrated framework that enables large-scale e...

Mothers’ experiences of bonding with their subsequent child following a previous perinatal bereavement

Introduction Perinatal bereavement can significantly affect a woman’s psychological wellbeing and shape subsequent experiences of pregnancy and motherhood. However, no studies to date have qualitatively explored the impact of different types of perinatal bereavement experiences o...

Local Structure and Dynamics of Three-Dimensional Covalent Organic Frameworks

Abstract Resolving and controlling the local dynamical properties of covalent organic frameworks (COFs) remains a central challenge, particularly when assembled from large, flexible building units. Here, we combine synchrotron X-ray pair distribution function (PDF) analyses with...

ExonViz: Transcript visualization made easy

ExonViz is a simple tool to draw transcripts that include coding and non-coding regions. All exons are to scale and the reading frames of the exons are visible. Single or multiple variants along the transcript can be drawn and will automatically be shown in the correct location.

Procrastination among US college students: Prevalence and impact relative to common health and life issues

Procrastination is unnecessary delay that can cause various problems. There are uncertainties around how common exactly it is among students, how much it affects them, and how its prevalence and impact compare to those of other issues that students regularly face. Accordingly, th...

Prediction of prognosis and treatment effect of cervical cancer by immunogenic cell death-related genes

Background Immunogenic cell death (ICD) is a potential mechanism that mediates adaptive immune responses during anticancer therapy. However, expression patterns and clinical implications of ICD related genes in cervical squamous cell carcinoma and endocervical adenocarcinoma (CES...

A comparative analysis of graph neural networks through similarity-based information propagation across diverse network structures

Abstract Information propagation over graph-structured data depends critically on the quality of node representations learned by graph neural networks (GNNs). However, how different GNN architectures organize embedding spaces and how these representations influence downstream pro...

Epigenetic insights into extreme longevity in the world’s oldest terrestrial animal, Jonathan

Aldabra giant tortoises ( Aldabrachelys gigantea ) are exceptionally long-lived. We sequenced the genome and methylome of Jonathan, a 194-year-old Aldabra, to explore the molecular basis of his longevity. Relative to other giant tortoises ( A. gigantea and Chelonoidis abingdonii...

Reliability of machine learning methods for prediction of critical heat flux: an OECD/NEA benchmark study

Abstract Critical heat flux (CHF) prediction is a primary thermal-hydraulic requirement for water-cooled reactors. Machine-learning studies on the OECD/NEA Phase-1 benchmark report high in-distribution accuracy, but reliability under distribution shift is poorly characterised. Fo...

Cryptanalysis of multiparty key exchange protocols over a modified supertropical semiring

We present a cryptanalysis of a multiparty key exchange protocol over a modified supertropical semiring, as proposed in a recent work of R. Ponmaheshkumar, J. Ramalingam, and R. Perumal. Building on the established methods for solving linear systems A⊗x=b over the tropical semiri...

Evolution of dipole–dipole dynamics in cold ammonia collisions

Cold polar molecules offer fascinating prospects for ultracold chemistry and quantum physics. However, their inherent collision properties remain largely unknown, as it seems fundamentally impossible to reach sufficiently low energies by merging two beams of molecules with substa...

BioForge: A Fast and Safe Macromolecular Structure Preparation Library in Rust

Abstract Summary BioForge is the first macromolecular structure preparation library for Rust, complementing sequence-analysis libraries such as Rust-Bio with cleaning, geometry-based missing-atom repair, protonation, and solvation as a force-field-agnostic preprocessing stage. Ac...

Effects of Mineralogical Inhomogeneity on Aggregate Dust Optical Properties and Lidar Observables

Abstract Dust aerosols comprise irregular grains and aggregates with various mineralogical mixtures. However, most optical models use effective refractive indices to represent particles. This study develops an inhomogeneous aggregate model assigning mineral‐dependent refractive i...
