Design and Replication of Micro- and Nanotextured Polymer Surfaces: A Height-to-Pitch Criterion to Predict Hydrophobicity Enhancement

Abstract The present study examines how the replication of micro- and nanotextures on polymer surfaces enhances their hydrophobic properties and defines a geometric parameter required to obtain functional surfaces at an industrial scale. Nickel shims were fabricated by lithograph...

The presence of mahi-mahi at multi-predator feeding aggregations modifies striped marlin attack behaviour

Abstract Terrestrial multi-species predator feeding aggregations (MPFAs) are characterized by contest competition, but scramble competition is likely more common at MPFAs in pelagic waters. However, empirical investigations are rare. Aerial video was used to estimate abundances o...

The role of visual feedback in metacognitive judgments of motor performance

Predicting the outcome of one's actions is crucial for effective behaviour, yet the mechanical underpinnings of this metacognitive ability remain poorly understood. We investigated the impact of visual feedback on basketball players' ability to monitor the accuracy of their free...

Geometry-enforced topological chiral fermions in amorphous chiral metals

Since the prediction and observation of topological Weyl semimetals (chiral TSMs), there have been enormous efforts to characterize further condensed matter realizations of chiral fermions. These efforts were dramatically accelerated by the subsequent discovery of a profound link...

Parselets: An Abstraction for Fast, General-Purpose Algorithmic Information Calculus

This work describes the principled design of a theoretical framework leading to fast and accurate algorithmic information measures on finite multisets of finite strings by means of compression. One distinctive feature of our approach is to manipulate reified representations of th...

Challenges in reconstructing seasonally driven landslide motion from optical satellite data: insights from the Del Medio catchment, NW Argentina

Optical satellite images are a valuable resource for studying slow-moving landslides from space. However, monitoring displacement through pairwise image correlation and time-series inversion presents several challenges, including the impact of seasonality on measurement accuracy....

Adoption of, attitudes towards, and perceived challenges of digital health in hospice and palliative care among professionals in Germany: a national cross-sectional web-based survey

Abstract Background Digital health technologies may support communication, symptom management, continuity of care, and access to services in hospice and palliative care. National data on their adoption, on professionals’ attitudes, and on perceived barriers are scarce. We examine...

When Recruiters Meet Algorithms: Advice Taking and Bias in AI‐Assisted Recruitment

ABSTRACT This study examined whether professional recruiters revise their hiring decisions after receiving external advice under cognitive conflict, that is, when advice contradicts their initial evaluation. In a between‐subjects experiment, 1,208 recruitment professionals evalua...

Opening Pandora’s box: Paper mills in conference proceedings

OBJECTIVE: Paper mills are a growing threat to the integrity of science, yet their penetration in conference proceedings remains underexplored despite conferences being more important than journals in some scientific subfields. This study aims to identify papers in conference pro...

HySoP: Hybrid Simulation with Particles

Official release of the code.

Diffusion and gettering mechanisms of W and Fe in 300 mm silicon substrates

Metallic contamination is a major reliability issue in CMOS image sensor processing, where recombination-active impurities can increase dark current and pixel defects. In this work, the behavior of tungsten and iron is studied in several 300 mm silicon-based stacks under the same...

On the Cl2 plasma etching mechanisms of AlN micropillars: Carrier wafer impact

Plasma etching of aluminum nitride (AlN) is a critical step in the fabrication of advanced optoelectronic and electronic devices, particularly deep-ultraviolet light-emitting diodes based on nanowire architectures. In research and development, small AlN samples are commonly mount...

Orbital and Spin–Orbit Torque Interplay in Ta/W-Based Magnetic Tunnel Junctions with Vertical Nonlocal Switching

Abstract Spin–orbit torque (SOT) enables ultrafast, energy-efficient magnetization switching, making it promising for MRAM cache applications. However, current SOT-MRAM devices face write efficiency limitations, with charge-to-spin conversion (ξDL) reaching only ∼ 45%, well below...

Probabilistic Characterisation of Service Lifetime of Ageing Infrastructures

Abstract Ageing infrastructures are increasingly exposed to deterioration mechanisms related to time, environmental conditions, and increasing operational demands. Ensuring their safety and serviceability therefore requires continuous monitoring and reliable methods to assess the...

Learning-Based Methods and the Future of Numerical Ocean and Sea-Ice Modeling

The field of operational oceanography is undergoing a significant evolution with the increasing integration of artificial intelligence (AI) methods, which are complementing and, in some cases, redefining traditional numerical modeling approaches. This review explores how AI metho...

CEO stock ownership and firm default risk

Purpose This study examines the effect of chief executive officer (CEO) stock ownership on firm default risk. While equity-based incentives are expected to align managerial and shareholder interests and enhance firm survival, alternative mechanisms – such as CEO under-diversifica...

Tunnel collapses and adaptive support at rock-soil interfaces under low-to-medium overburden in tectonically disturbed rock masses

Tunnel stability in tectonically disturbed rock masses remains particularly challenging near rock–soil interfaces, where abrupt stiffness contrasts and heterogeneous geological structures can trigger collapse mechanisms that conventional rock mass classification systems do not ad...

Determining a graph from its reconfiguration graph

Given a graph G and a natural number k , the k -recolouring graph C k ( G ) is the graph whose vertices are the k -colourings of G and whose edges link pairs of colourings which differ at exactly one vertex of G . Recently, Hogan et al. proved that G can be determined from C k (...

Climatology and trends of extreme precipitation in France: evaluation of an explicit-convection regional climate model

Climate change is intensifying the global water cycle, with extreme precipitation events increasing in frequency and intensity at the global scale. While trends in daily precipitation extremes are well-documented, sub-daily extremes – critical for flash flood risk – remain poorly...

Advancing conflict research and response through satellite-derived data

Abstract With armed conflicts at a historic high and attacks on civilians rising 1 , understanding the evolving nature of conflict is a critical research priority. The current paradigm in conflict research relies heavily on text-based data, using fatalities as the primary—and oft...
