Distinct Modes of Quantum Information Transfer in Power–Law Long-Range Spin Networks

We identify different regimes of quantum state transfer in long-range coupled spin-12 systems, where naturally occurring power–law interactions enable rapid, high-fidelity transfer with minimal engineering. Across a broad range of interaction profiles, from effectively nearest-ne...

Naming and Shaming to Protect Civilians During Peacekeeping: Lessons from South Sudan

Abstract What can the United Nations do to strengthen the protection of civilians when it fails? When missions struggle to protect civilians, high‐level naming and shaming of non‐responsive units within the operation can occur to reorient the operation. Shaming helps rehabilitate...

Holographic Complexity as a Probe of Boundary Entropy in AdS/BCFT

We investigate how the sewing operations familiar from topological quantum field theory provide a useful organizational framework for semiclassical AdS/BCFT path integrals. Our purpose is not to identify AdS/BCFT with a topological field theory: the bulk geometry, the end-of-the-...

The Right to Communicate: UNESCO and the politics of global communication, 1969–1987

Abstract The Right to Communicate (RtC) is the idea that individuals possess not only the freedom to ‘seek, receive and impart information’, as laid down in Article 19 of the Universal Declaration of Human Rights (UDHR), but also the right to communicate horizontally with their p...

A sequential hybrid framework for medical feature selection using population transfer

Abstract Feature selection is a crucial preprocessing step in medical machine learning, where datasets frequently contain redundant, irrelevant, or highly correlated features. Although metaheuristic algorithms have shown promising results for wrapper-based feature selection, thei...

Comparison of a Parametric Physics-Informed Neural Network and a Tensorial Reduced-Order Model for the Shallow-Water Dam-Break Problem

We develop two parametric data-driven reduced models: a physics-informed neural network (PINN) and a non-intrusive tensorial reduced-order model (TROM), and apply both approaches to the parametrized one-dimensional shallow-water dam-break problem. Both reduced models do not requi...

Leaving the Account, Not Just the Organization: Work Strain, Career Growth, and Reward Fairness as Predictors of Turnover Intention in a Philippine BPO Account

Employee turnover remains a persistent operational problem in the Philippine Business Process Outsourcing (BPO) industry, yet many turnover studies continue to treat retention as a broad organizational issue rather than an account-level phenomenon. This study addressed this gap b...

When heat hits: Short-run saving and withdrawal behavior among microfinance clients in Benin

Increased access to finance is widely viewed as a key driver to increase adaptive capacity in response to climate change. However, apart from limited studies on borrowing behavior, little is known about how exposure to extreme heat impacts microfinance clients’ financial behavior...

Growing into gender: Funerary practice of boys and girls in the Bronze Age Maros culture (2100 − 1700 BC)

Abstract This study investigates the relationship between biological sex and gendered funerary practices among children of the Bronze Age Maros culture in northern Serbia. Biological sex was determined for 77 non adult individuals (< 18–22 years), for 76 of them using peptide bas...

Spin-current-controlled anisotropic deformation of magnetic lump solitons

We investigate a (2+1)-dimensional nonlinear spin system containing an effective spin-current transport term. Based on its integrable structure, exact magnetic lump solutions are constructed on a rotating spin background, including both fundamental and higher-order configurations...

Preserved higher-order mentalising during strategic interactions after medial prefrontal cortex damage

Abstract Mentalising, the ability to infer the beliefs and intentions of others, is essential for successful social interaction. Previous studies have implicated the medial prefrontal cortex in mentalising, but whether this region is necessary for higher-order mentalising remains...

Integrated analysis of soil organic matter quality and phosphorus forms support a comprehensive evaluation of biogeochemical recovery during natural tropical dry forest regeneration

This dataset contains soil calorimetric and phosphorus nuclear magnetic resonance (^31P NMR) data from tropical dry forest soils across a natural regeneration in the Yucatán Peninsula, Mexico.Soil samples were collected from the upper 10 cm (0–10 cm) of the mineral soil profile i...

Universal Scaling and Relaxation in Decaying Turbulence of Bose Gases

Abstract Understanding the relaxation dynamics of isolated quantum systems remains a central challenge in nonequilibrium physics. In this short review, we discuss recent experimental and theoretical advances in universal dynamics of turbulent Bose gases, with particular emphasis...

Hurried science and the tracking problem

In times of crisis, science tends to move fast. However, speeding up science often involves deliberate compromises to the scientific norms that are meant to guarantee the reliability of scientific results in normal circumstances. Call this hurried science. Some of the compromises...

A Candidate Outburst of the Cool ZZ Ceti Star LP 119-10 in Archival TESS and ZTF Photometry

LP 119-10 (WD 0502+540, TIC 252385237) is a known hydrogen-atmosphere pulsating white dwarf (ZZ Ceti star, DAV) near the cool edge of the instability strip. This preprint reports a single brightening event found in archival TESS 120-s photometry of sector 86. On 2024 December 4 t...

Initial Orbit Determination of Low-Earth-Orbiting Objects Using Multi-Site Space-Based Optical Observations

Space Situational Awareness (SSA) is a growing field of study which provides knowledge of Resident Space Objects (RSOs) to help maintain a safe and sustainable space environment around Earth. A primary component of SSA is obtaining Initial Orbit Determinations (IODs) of these obj...

Hydration Changes are Essential for Efficient Breakdown of Faropenem by the L1 Metallo-β-lactamase

Abstract Metallo-β-lactamases (MBLs) are key contributors to antimicrobial resistance (AMR). The L1 MBL, originally from Stenotrophomonas maltophilia, is a tetrameric, dizinc, subclass B3 MBL that efficiently hydrolyzes most β-lactam antibiotics and evades inhibitors that act on...

Light‐Driven Control of Polar Order in Ferroelectric Nematic Liquid Crystals

ABSTRACT Ferroelectric nematic (N F ) liquid crystals are polar fluids that combine long‐range orientational order with spontaneous macroscopic polarization and exceptionally large dielectric permittivity. While these properties make N F materials attractive for responsive soft d...

From protogalaxy through thick and thin: Why did the Milky Way evolve in three kinematic phases?

Abstract APOGEE and Gaia data suggest the Milky Way’s kinematic structure evolved through three distinct phases: a disordered protogalaxy, which ‘spun up’ into a thick stellar disk, and then ‘cooled down’ to a final cold, thin stellar disk. We use a suite of FIRE-2 cosmological z...

Competition and soil conditions limit the growth of High Arctic non‐native plants

Non-native vascular plant species in the High Arctic are currently restricted mainly to settlements and other anthropogenically disturbed areas. The reasons for this remain unclear, but climate or dispersal do not appear to be the main limiting factors. Instead, biotic interactio...
