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...

Tuning the Architecture of High-Density Bottlebrush Block Copolymers to Control Their Photonic Properties

Abstract The backbone rigidity of bottlebrush block copolymers (BBCPs) induced by the dense branches distributed along their polymeric backbones has made them materials of interest for fast self-assembly of photonic materials. Today, the rigidity of BBCPs is limited by the maximu...

Domain‐Wall Circulation Gating and Pinning via Compositional Engineering of Cylindrical Nanowires

ABSTRACT Spintronic devices based on cylindrical magnetic nanowires have been proposed as a route toward three–dimensional (3D) information storage and processing by harnessing the controlled motion of domain walls (DWs). In this geometry, the Bloch‐point wall (BPW) is the charac...

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...

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....

Faithful Universal Graphs for Minor-Closed Classes

Abstract. It was proved by Huynh et al. [ Universality in Minor-Closed Graph Classes, preprint, arXiv:2109.00327, 2021] that any countable graph containing every countable planar graph as a subgraph has an infinite clique minor. We prove a finite, quantitative version of this res...

Rigidity of complete Kähler–Einstein metrics under cscK perturbations

In this paper, we study constant scalar curvature Kähler (cscK) metrics on complete non-compact Kähler–Einstein manifolds. We give sufficient conditions under which a cscK perturbation of a Kähler–Einstein metric must remain Kähler–Einstein. As a model case, we prove that the Ber...

Thickness-Dependent Spintronic Terahertz Emission in Molecular Beam Epitaxy-Grown PtTe2: From Semiconductor to Type-II Dirac Semimetal

Abstract Spintronic THz emitters are the most practical broadband sources, but their performance is constrained by the spin Hall conductivity of the conversion layer. We show that PtTe2, a type II Dirac semimetal, overcomes this limitation through thickness-driven electronic phas...

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...

Interface engineered perpendicular magnetic anisotropy-controlled propagation of magnetic domain

We report the impact of ferromagnetic layer thickness and stack configuration on the magnetic properties, perpendicular magnetic anisotropy (PMA), modified magnetization switching mechanisms, and creep regime domain wall (DW) dynamics, including their propagation velocity, in a P...

Infant-caregiver vocal contingency changes across varying interpersonal space

Vocal contingency between caregivers and infants is a fundamental building block for socio-communicative development. This paper investigates vocal contingency in home settings and how it varies as a function of the physical distance between infants and their caregivers. We recor...

Targeting the Complement C1 Proteases Using Camelid-Derived Single Domain Antibodies: Production, Characterization and Possible Application for Tissue/Fluid Analysis

Background. The complement C1r and C1s proteases initiate the classical complement pathway within the C1 complex, but emerging evidence points to additional roles in tissues, including cell-intrinsic functions linked to cancer and connective tissue disorders. Few tools are availa...

A principle of least time before Fermat?

This article aims to clarify the status of two early statements concerning least time, one from Martinus Hemerl's optics (quanto natura citius potest pertingere ad suum effectum), the other from Leonardo da Vinci's notebooks (nel più breve tempo sia possibile). A comparison of th...

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...

Arithmetic properties of the Taylor coefficients of differentially algebraic power series

Let f = ∑ n = 0 ∞ f n x n ∈ ℚ ¯ 〚 x 〛 be a solution of an algebraic differential equation Q ( x , y ( x ) , ⋯ , y ( k ) ( x ) ) = 0 , where Q is a multivariate polynomial with coefficients in ℚ ¯ . The sequence ( f n ) n ≥ 0 satisfies a non-linear recurrence, whose expression i...

Overcoming Reversibility: Borrowing Hydrogen Enables Enantioselective Intermolecular Oxa-Michael Addition to α,β-Unsaturated Aldehydes

Abstract Chiral 1,3-dioxygenated motifs are key scaffolds in bioactive natural products, yet their synthesis via intermolecular oxa-Michael addition to α,β-unsaturated aldehydes remains challenging notably due to the high reversibility of the oxygenated nucleophile addition. This...

HySoP: Hybrid Simulation with Particles

Official release of the code.

Variance reduction for forces and pressure in variational Monte Carlo

We present simple and practical strategies to reduce the variance of Monte Carlo estimators. Our focus is on variational Monte Carlo calculations of atomic forces and pressure in electronic systems, although we show that the underlying ideas apply more broadly to other observable...

Semi-convection in rotating spherical shells: flows, layers and dynamos

Large regions of giant planets are thought to possess unstable thermal gradients stabilised by gradients of heavy-element composition. Such a fluid can develop semi-convection, a double-diffusive instability driven by the unequal molecular diffusivities of heat and composition. W...

Arrival-Time Distributions as a Probe of the Preferred Foliation in Relativistic Bohmian Mechanics

Relativistic extensions of de Broglie–Bohm theory postulate a preferred foliation of spacetime, an additional structure essential for defining simultaneous configurations on Minkowski spacetime but conventionally believed to be empirically undetectable at quantum equilibrium. In...
