Handwriting Isochrony in Autistic and Non-Autistic Children

Handwriting difficulties are frequently reported in autistic children and may interfere with academic performance. However, whether fundamental motor principles such as isochrony are preserved in autism remains largely unexplored. To address this question, fifty-five autistic and...

Observation of a supersolid phase in a spin-orbit coupled exciton-polariton Bose-Einstein condensate

In Bose-Einstein condensates, spin-orbit coupling (SOC) produces supersolidity. It is a peculiar state of matter, which, in addition to the superfluid behavior, shows periodic density modulation typical for crystals. Here, we report the fabrication of an original type of optical...

Passive ankle exoskeleton assistance selectively modulates triceps surae neural control during balance

Wearable assistive devices have potential to improve human balance, but their effectiveness remains limited by an incomplete understanding of how mechanical assistance influences neuromuscular control. This study aimed to determine the neural adaptations in the control of lower l...

Sampled-Based Guided Quantum Walk: Non-variational quantum algorithm for combinatorial optimization

We introduce SamBa-GQW, a novel quantum algorithm for solving binary combinatorial optimization problems of arbitrary degree with no use of any classical optimizer. The algorithm is based on a continuous-time quantum walk on the solution space represented as a graph. The walker e...

Reflector‐Free, Highly Confined Love‐Like SAWs Enabled by a Phononic Metasurface for Real‐Time Monitoring of Cell Dynamics

ABSTRACT Surface acoustic wave (SAW) devices are widely used in sensing and biosensing but generally suffer from strong attenuation in liquid environments. Conventional approaches rely on reflectors to reduce these losses, yet these components remain difficult to optimize: limite...

Design and analysis of smooth geometry‐conforming lattices via Generalized Bézier patches

Abstract We propose a novel methodology to model globally G 1 geometry‐conforming metamaterials using Generalized Bézier‐based (GB) patches. Since every canonical tile is inscribed in a unit cube, we exploit its natural decomposition in octants and design multi‐sided patches for...

Interfacial Electric Fields in Water Nanodroplets Are Weakly Dependent on Curvature and pH

Abstract The origin of enhanced reactivity in aqueous microdroplets remains unresolved, with interfacial electric fields (IEFs) frequently proposed as catalytic drivers. Here, we present a quantum-mechanical, spatially resolved characterization of the electric field at air-water...

Development and early implementation of a brief 2-day multidisciplinary parent training group for paediatric ARFID: A feasibility and acceptability study

OBJECTIVE: Many children with avoidant/restrictive food intake disorder (ARFID) cannot access appropriate care, as existing individual and family treatments are scarce, long and costly. We developed a brief 2-day (12-h) multidisciplinary parent training group and assessed its fea...

Antcar: Simple Route Following Task with Ants-Inspired Vision and Neural Model

The goal of this project is to develop a new method of Route following for mobile robots in a GNSSdenied environment like urban canyons or indoor. We used a robust biologically constrained neural model inspired by ants developed previously in simulation to assess the familiarity...

The geometry of gametic dispersal in a flying mammal, Rhinolophus hipposideros

Abstract Dispersal influences population and evolutionary dynamics, in a manner that depends on by which dispersal strategies gene flow occurs. In some species, mating partners move exclusively for mating, dispersing genes but not individuals. This is the case in many bat species...

Self-assembled nucleolipid G-quadruplexes act as multitarget decoys for oncogene suppression in pancreatic cancer

Abstract KRAS mutations drive multiple cancers and represent an important therapeutic target, together with other oncogenic regulators such as MYC , KIT , and BCL2 that are critically involved in pancreatic cancer. Here we describe a novel therapeutic strategy based on stable nuc...

Sensitive reverse transcription-digital droplet PCR-based discrimination of hepatitis delta virus RNAs reveals differential effects of interferon-α on viral RNA species

Hepatitis delta virus (HDV) replication relies on the production of distinct viral RNA species, including genomic (HDV-G), antigenomic (HDV-AG) and mRNAs (HDV mRNAs), which differ in abundance and function. However, the lack of sensitive and quantitative approaches allowing their...

A global consistent database of plankton and detritus from in situ imaging by the Underwater Vision Profiler 5

Plankton and detritus are essential components of the Earth's oceans influencing biogeochemical cycles and carbon sequestration. Climate change impacts their composition and fluxes, and marine ecosystems as a whole. To improve our understanding of these changes, standardized obse...

Advances in 3D Bioprinting for Breast Cancer Modeling: Tumor Microenvironment, Metastasis, and Drug Screening

The tumor microenvironment (TME) is a complex and heterogeneous milieu encompassing biological and biochemical events and diverse physical, chemical, and mechanical interactions between tumor and stromal cells. This heterogeneity plays a pivotal role in regulating tumor progressi...

Perceptual-motor processes in cycling: A scoping review

Cycling is increasingly recognized as a sustainable and efficient mode of transport, demanding a high level of perceptual-motor coordination for safety and performance. Despite extensive research on biomechanics and physiological capacities in cycling, perceptual-motor dynamics –...

Real‐Time Observation of Soliton Buildup and Self‐Organization in a GHz Harmonic Mode Locked Fiber Laser

ABSTRACT Ultrafast fiber lasers operating at GHz repetition rates are critical for applications requiring high‐speed optical pulse sources. To achieve such rates, passive harmonic mode locking (HML) constitutes a logical pathway, whose practical implementation is hampered by the...

Development of ultrafast and radiation-hard GAGG for the next-generation of High-Energy Physics calorimeters

The evolution of High Energy Physics (HEP) toward future collider experiments with High Luminosity (HL), such as the HL-LHC, requires the development of scintillating materials that combine high density, excellent radiation hardness and an ultrafast response. While Cerium-doped G...

Sensitivity of neutrino oscillations to the Earth’s interior properties

Understanding the Earth’s deep interior remains challenging, as traditional geophysical methods face ambiguities in linking seismic observations to temperature, composition, or mass density variations. Atmospheric neutrinos, produced by the constant flux of cosmic rays colliding...

Metric and spectral aspects of random complex divisors

For any integer n\geq 2 , we prove that for any large enough integer d , with large probability the injectivity radius of a random degree d complex hypersurface in \mathbb{C}P^{n} is larger than {d^{-(n+2)/2}} . Here the hypersurface is endowed with the restriction of the ambient...

Soft-Templated Carbon Models Elucidate the Anomalous Increase of Capacitance in Nanopores

Abstract Supercapacitors are electrochemical energy-storage devices distinguished by rapid charge–discharge and high power density. The observation of anomalously enhanced capacitance in nanoporous carbons challenged classical descriptions of double-layer charging and stimulated...
