Rational Mechanics of Material Strength in Brittle Solids

Abstract Material strength is a classical concept that has recently found renewed applications in fracture mechanics, especially in models for crack nucleation in brittle solids. In this paper, we formulate material strength in the setting of finite elasticity and examine its geo...

Cerebellar Network Organization in Parkinson's Disease: Functional Connectivity across Motor and Cognitive Circuits

Abstract Background The cerebellum is increasingly recognized as a key contributor to cognitive reserve and network organization in Parkinson's disease (PD). However, the relationship of cerebello‐cortical and cerebello‐basal ganglia connectivity with cognitive status and nigrost...

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...

The role of white matter microstructure in the association between childhood maltreatment and adult post-traumatic symptoms

Abstract Childhood maltreatment (CM) is a risk factor for adult post-traumatic symptoms and white matter (WM) alterations. It remains unknown how WM microstructure is affected alongside two common military conditions, post-traumatic stress disorder (PTSD) and mild traumatic brain...

Hierarchical generative modeling for the design of multi-component systems

Abstract The functionality of catalysts, enzymes, and supramolecular assemblies emerges not from individual molecules alone, but from the subtle interplay between multiple components arranged in complex systems. Designing such systems is a grand challenge: the combinatorial explo...

Minimal-Degree Foliations on Cominuscule Grassmannians

Abstract Let X be a cominuscule Grassmannian (equivalently, an irreducible Hermitian symmetric space), and let p be an integer. We compute the minimum l ( p ) such that $$H^0(\Omega _X^p(l(p))) \ne 0.$$ H 0 ( Ω X p ( l ( p ) ) ) ≠ 0 . This allows us to conclude that any codimensi...

First-principles investigation of the pressure dependent physical properties of intermetallic kagome ZrRe2

Abstract Intermetallic compounds hosting Kagome lattices have drawn great interest as a vibrant emerging field in condensed matter physics. We present a first-principles density functional theory (DFT) investigation of the pressure-dependent structural, electronic, mechanical, th...

The role of water temperature and food availability in shaping immunity and body condition of Odonata: Impacts of deprivation on larval development

Abstract Global climate change and intensified human activities are increasingly affecting aquatic ecosystems, including Odonata, whose life cycles and physiology are closely linked to freshwater conditions such as temperature and food availability. While patterns influencing the...

A Boothby–Wang Construction in Generalized Contact Geometry

ABSTRACT We establish a generalized analogue of the Boothby–Wang theorem in generalized contact geometry, along with related results. We present a general method for constructing examples of generalized contact structures that are not of Poon–Wade type, and even examples that fai...

Arctic climate tipping points under delayed CO2 emissions mitigation

A $$3\times 3$$ linear q-difference system with $$E_8^{(1)}$$-symmetry

Abstract We present a linear q -difference equation of rank 3, which admits the affine Weyl group symmetry of type $$E_8^{(1)}$$ E 8 ( 1 ) . This equation has essentially 8 parameters and 2 accessory parameters. We characterize this equation by the spectral type of q -difference...

The unseen pain of the Vietnam War: long-term effects of Agent Orange on labor market outcomes

Abstract We examine the long-term labor market consequences of exposure to Agent Orange during the Vietnam War, focusing on cohorts whose childhoods overlapped the spraying period. Exploiting district-level variation in herbicide exposure intensity, we find exposed individuals at...

Beyond snapshots: a Bergsonian approach to including lived experiences in social work research

Qualitative methods have significantly advanced the inclusion of lived experience in social work research. This article explores how Henri Bergson's concepts of durée and intuition can contribute to a distinct vocabulary for engaging the temporal, ambiguous, and textural dimensio...

Ab initio complex Langevin computation of the roton gap for a dipolar Bose condensate

We compute from first principles the dispersion relation $ω(k)$ of a dipolar Bose gas of erbium atoms close to the roton instability by employing the Complex Langevin (CL) algorithm. Other than the path integral Monte Carlo algorithm, which samples the quantum mechanical path int...

High-throughput exploration of refractory high-entropy alloys for strength and plasticity

Refractory high-entropy alloys (RHEAs) are compositionally complex materials which have been demonstrated to have the potential for exceptional strength at high operating temperatures. However, their composition space is vast, and other property requirements, such as acceptable p...

Few bilinear operators on spaces of continuous functions

Motivated by recent work exhibiting a locally compact scattered space L constructed under Ostaszewski’s ♣-principle, which yielded a complete classification of linear operators on C0(L×L), we extend the analysis to the bilinear setting. We show that, for this space L, every bilin...

Mean-Field Dynamics of the Bose–Hubbard Model in High Dimension

Abstract This paper is a first step toward rigorously establishing the validity of mean-field approximations for the dynamics of quantum systems in a large dimensional limit. Our result is a derivation of the large d mean-field limit of the Bose–Hubbard model on a square lattice....

Emergence of nonequilibrium Lieb excitations in periodically-driven strongly-interacting bosons

We study the exact nonequilibrium spectral function of a gas of strongly correlated Tonks-Girardeau bosons subjected to a strong periodic drive. Utilizing the theory of Floquet spectral function in conjunction with the Bose-Fermi mapping theorem, we show that nonequilibrium Lieb...

Bayesian inference of the climbing grade scale

Abstract Climbing grades are used to classify a climbing route based on its perceived difficulty, and have come to play a central role in the sport of rock climbing. Recently, the first statistically rigorous method for estimating climbing grades from whole-history ascent data wa...
