Robot in a crib: How a playing robot helps us understand sensorimotor contingency learning

Learning sensorimotor contingencies—that is, the link between one’s actions and their sensory effects—is fundamental to developing body knowledge, understanding causality, and developing a sense of agency. In developmental psychology, this process is classically studied using the...

New mechanistic insights into the widely used LiPO2F2 additive enabled by ultra-high-resolution FTICR-MS

Understanding how electrolyte additives influence the formation and evolution of the solid electrolyte interphase (SEI) is essential for improving the durability of lithium‑ion batteries. In this work, we investigate the role of lithium difluorophosphate (LiPO2F2, LiDFP) in 1 M L...

Contribution of mechanical forces in multiciliated cell differentiation

Abstract Multiciliated cells, through the coordinated beating of motile cilia, are vital for moving fluids in the brain and mucus in the airways and in the reproductive organs. Their dysfunction leads to diseases, associated with chronic airway infections, subfertility and ventri...

SRF fusion oncogenes encode constitutively activated chimeric transcription factors in myoid soft tissue tumors

ABSTRACT SRF fusion genes drive the pathogenesis of muscle-related soft tissue tumors, including subsets of perivascular tumors, inflammatory myofibroblastic tumor, and rhabdomyosarcoma. SRF encodes Serum Response Factor, a well-characterized transcription factor that regulates m...

Optimal sequential change-point detection for Markov models under probability criteria over short time intervals

In this paper, we study sequential change detection problems in the Bayesian framework under the probability delay risk according to which the detection goal is to minimize the probability that the detection delay will exceed some admissible delay level. To do this, we represent...

Quantum Entropic Relationalism (QER): Contemporary Debates and Theoretical Frontiers

Entropy has evolved from a secondary thermodynamic property (Clausius, 1865) to a potentially fundamental organizing structure of physical reality, particularly through its gravitational manifestation in the Bekenstein–Hawking formula. This article systematically reviews four the...

Energy-level alignment of vacancy-ordered halide double perovskites

Vacancy-ordered double perovskites have emerged as lead-free alternatives, offering remarkable stability and compositional tunability for optoelectronic applications. In this study, we provide first-principles insights into their electronic properties, surface stability, and ener...

Frequency control of superconducting resonators using integrated interferometers

Predictable frequency trimming of superconducting resonators at liquid-helium temperatures requires a tuning element whose usable range remains well defined despite screening currents and hysteresis. Here, we realize flux-controlled λ/4 coplanar-waveguide resonators terminated by...

Differentiable Forward Modeling for Efficient and Accurate Shear Inference

Forthcoming Stage-IV dark energy optical surveys, such as LSST, have the ambitious goal of measuring cosmological parameters at sub-percent precision. Realizing their full scientific potential requires very precise measurement of the cosmic shear signal and control of correspondi...

A Biomimetic Breast Tumor‐On‐Chip Platform Reveals Mesenchymal Marker Upregulation Following Gold Nanorod Photothermal Therapy

Photothermal therapy (PTT) using plasmonic nanoparticles has emerged as a promising strategy for localized cancer treatment, yet physiologically relevant models for assessing cell-line model-dependent responses remain limited. Here, we engineered a breast tumor-on-chip platform t...

A nationally representative One Health multi-pathogen serosurvey in Cambodia: study protocol for the RACSMEI mixed-methods study

Abstract Background Cambodia faces a high and complex burden of zoonotic, vector-borne, vaccine-preventable and environmentally transmitted infections, driven by intensive human–animal–environment interactions. However, nationally representative data integrating human, animal and...

Should I stay or should I go? Frog breeding responses to drought events and alien predators

Abstract Climate change is a major driver of biodiversity loss worldwide, increasingly acting through extreme climatic events such as droughts. Beyond their direct impacts on habitat availability, droughts can also generate indirect effects by altering ecological interactions, su...

A Hybrid High-Order Method for the Power-Law Brinkman Problem with Robust Error Estimates in all Regimes

Abstract. In this work, we propose and analyze a new hybrid high-order method for the Brinkman problem for fluids with power-law viscosity. The proposed method supports general meshes and arbitrary approximation orders and is robust in all regimes, from pure (power-law) Stokes to...

The rod bipolar cell pathway contributes to surround responses in OFF retinal ganglion cells

Abstract Sensory neurons can be influenced by stimuli beyond their receptive field center, yet the mechanisms underlying this surround modulation remain poorly understood. In the retina, many OFF ganglion cells exhibit responses to ON stimulation outside their receptive field cen...

Arctic sea ice predictability on daily-to-weekly timescales: sensitivity to initial positional errors under different rheology formulations

Abstract. We investigate short-term (daily-to-weekly) winter Arctic sea-ice predictability using a coupled ice–ocean model, and focusing on how sensitive forecasts are to initial uncertainty in the location of sea ice features (e.g., leads, ridges, etc.). In this context, two rhe...

4D Printing of Magneto‐Active Soft Elastomers via Efficient Active Mixing Direct Ink Writing

ABSTRACT 4D printing relies on the 3D printing of materials that respond to various stimuli after printing. Among these, magneto‐active elastomers readily react to magnetic fields, particularly at high magnetic particle loadings. For soft silicones with high particle contents, di...

Titanium‐Catalyzed Defluorination of Poly(Vinyl Fluoride) and Poly(Vinylidene Fluoride) Under Friedel–Crafts Conditions

ABSTRACT The defluorination of poly(vinyl fluoride) (PVF) and poly(vinylidene fluoride) (PVDF) fluoropolymers catalyzed by titanium species in the presence of triethylsilane (Et 3 SiH) and aromatic solvents is reported. Commercially available Ti complexes (e.g., [Cp 2 TiCl 2 ] (...

Early development of anoxia prior to the main euxinic phase of the Jenkyns Event on the margin of the Western Tethys (Sachrang Basin, Eastern Alps)

ABSTRACT Although the global expansion of oxygen‐depleted marine environments during the Early Toarcian Jenkyns Event (or Toarcian Oceanic Anoxic Event) is primarily inferred from successions in the NW European epicontinental basins, the timing of the expansion of anoxia in Tethy...

Comment on “The elusive fluid‐and‐crystal coexistence state in simulations of monodisperse, hard‐sphere colloids”

Abstract In a recent article [1], Wang et al. discuss the absence of simulations of monodisperse hard spheres in which a metastable fluid spontaneously nucleates into a stable fluid‐crystal coexistence. Here, we show that such a simulation can be readily accomplished with standar...
