Wearable sweat sensor can detect responses to physical, emotional and pharmacological stress
Most people are well aware of the effects of chronic stress in the modern world. While some stress can be a good thing, like the type of stress your body feels during an intense workout, prolonged or chronic stress can lead to a myriad of health problems, including anxiety, heart disease, and inflammation. And, at a larger scale, the high prevalence of chronic stress in the population increases the burden on public health systems.

To be clear, none of this is to say "this is definitely fake evidence." People talk in really strange ways when they're under stress. People are weirder than you think. Reality is weirder than you think. I don't think this is clearly "this is fabricated."
But I don't just trust it by default, especially when it lines up really well with what the administration wants.

Holography for stress-energy tensor flows
We study the holographic description for general stress-energy tensor deformations in arbitrary dimensions using the metric flow approach. Mixed boundary conditions corresponding to these deformations emerge from solutions to the metric flow equations. To test this proposal, we analyze planar AdS black holes with such boundary conditions and find that the deformed energies satisfy flow equations consistent with the field theory interpretation. We further derive the commuting condition for stres…

Stress Response of Jammed Solids: Prestress and Screening
Unlike classical elasticity, where stresses arise from deformations relative to a stress-free reference configuration, rigidity in amorphous systems is maintained by disordered force networks that generate internal prestress. Previously, we introduced a ''stress-only'' formulation, where mechanical equilibrium resembles Gauss's law in a rank-2 tensor electrostatics with vector charges, and demonstrated that the mechanical response of jammed solids is described by the dielectric response of this…

Emotions exert an immense influence over human behavior and cognition in both commonplace and high-stress tasks. Discussions of whether or how to integrate large language models (LLMs) into everyday life (e.g., acting as proxies for, or interacting with, human agents), should be informed by an understanding of how these tools evaluate emotionally loaded stimuli or situations.

Universal Deformations in Compressible Isotropic Cauchy Elastic Solids with Residual Stress
We investigate universal deformations in compressible isotropic Cauchy elastic solids with residual stress, without assuming any specific source for the residual stress. We show that universal deformations must be homogeneous, and the associated residual stresses must also be homogeneous. Since a non-trivial residual stress cannot be homogeneous, it follows that residual stress must vanish. Thus, a compressible Cauchy elastic solid with a non-trivial distribution of residual stress cannot admit…

Quantum-corrected three-dimensional AdS space-time
We study the backreaction of a quantum scalar field on anti-de Sitter (AdS) space-time. The renormalized expectation value of the stress-energy tensor operator (RSET) for a quantum scalar field acts as a source term on the right-hand-side of the Einstein equations for the quantum-corrected metric. We find the RSET for a nonrotating thermal state on global AdS in three dimensions and compare this with results from relativistic kinetic theory. We then solve the linearized quantum-corrected Einste…

Comparison of three random field sampling methods for high-resolution Bayesian inversion with application to a plane stress problem
Bayesian inversion aims to provide uncertainty quantification of posterior estimates conditional on observations. When the inferred parameter is a continuous spatial function, one common strategy is to model it as a random field. Several random field sampling strategies exist. In this article, we investigate three different approaches in terms of numerical efficiency and influence on the posterior distribution. These approaches are based on (i) Karhunen-Loeve and (ii) wavelet expansions, and (i…

Generalization of the viscous stress tensor to the case of non-small gradients of hydrodynamic velocity: a path to numerical modeling of turbulence non-locality
Generalization of the Chapman-Enskog method to the case of large gradients of hydrodynamic velocity allowed us to obtain an integral (over spatial coordinates) representation of the viscous stress tensor in the Navier-Stokes equation. In the case of small path lengths of the medium disturbance, the tensor goes over to the standard form, which, as is known, is difficult to apply to the description of tangential discontinuities and separated flows.

The setting is a homogeneous isotropic elastic body containing an inclusion separated by a thin interface endowed with higher-order surface energy. Using displacement-stress measurements on the exterior boundary, expressed through a certain Dirichlet-to-Neumann map, we show uniqueness in recovering both the shear and interface parameters, as well as the shape of the inclusion.

Rock geophysical properties are widely reported to exhibit non-linear behaviours under low-stress conditions (below 10-20 MPa) before transitioning to the linear elastic stage, primarily due to the closure of microcracks and grain interfaces. Image-based modelling of rock deformation struggles to effectively characterise the microcrack closure effect because of the partial-volume effect, where image voxels are larger than microcracks and contain both pore and solid phases.

The relationship between force and motion remains unclear, however, because the forces are a sum active and passive contributions. Here, we show that the active forces can be decoupled from the passive by careful investigation of the distribution of shear stress against strain rate. With this method, we show experimentally that the order of magnitude of passive tis…

To fill in this gap, we present SCARF, the first general framework that evaluates water impact of computing by factoring in both spatial and temporal variations in water stress. SCARF calculates an Adjusted Water Impact (AWI) metric that considers both consumption volume…

Wall Shear Stress Estimation in Abdominal Aortic Aneurysms: Towards Generalisable Neural Surrogate Models
Abdominal aortic aneurysms (AAAs) are pathologic dilatations of the abdominal aorta posing a high fatality risk upon rupture. Studying AAA progression and rupture risk often involves in-silico blood flow modelling with computational fluid dynamics (CFD) and extraction of hemodynamic factors like time-averaged wall shear stress (TAWSS) or oscillatory shear index (OSI). However, CFD simulations are known to be computationally demanding. Hence, in recent years, geometric deep learning methods, ope…

Thermal scalar field stress tensor on a two dimensional black hole and its near horizon properties
We calculate the thermal renormalized energy-momentum tensor components of a massless scalar field, leading to trace anomaly, on a $(1+1)$ dimensional static black hole spacetime. Using these, the energy density and flux, seen by both static and freely-falling observers, are evaluated. Interestingly for both these observers the aforementioned quantities in Unruh and Boulware vacua are finite at the horizon when the scalar field is in thermal equilibrium with the horizon temperature (given by th…

PBPU Elastomer Network Architecture Determination via Corresponding States Analysis of Mechanical Behavior
In this work we examine the effect of R=[NCO]/[OH] in the R=<1 regime, on the resultant structural topology of polybutadiene polyurethane (PBPU) elastomer networks based on hydroxy-terminated polybutadiene (HTPB). We employ stress-elongation behavior and its modeling, as a tool. We examine this property via a combination of our model for the finite chain phantom networks incorporating the HTPB structural information, with the slip-tube model from the literature, suitably modified phenomenologic…

Imaging 3D Printed Fracture Networks under Stress using X-Ray Computed Tomography
We present a novel experimental approach based on 3D printing and X-ray computed tomography to characterize fracture aperture distribution and evolution in 3D fracture networks under varying stress loading conditions. We validate our methodology by comparing experimentally measured stress-dependent fracture apertures with both analytical solutions and numerical simulations, for both single fracture and fracture network scenarios. We show that, for fracture deformation under linear elastic regim…

Amorphization-Mediated Si-I to Si-V Phase Transition and Reversible Amorphous-Si-V Phase Memory in Silicon Nanoparticles
Molecular dynamics simulations using a Gaussian Approximation Potential (GAP) reveal a stress triaxiality driven, two-step Si-I (diamond cubic) to Si-V (simple hexagonal) phase transition pathway in a spherical Si nanoparticle with a 10 nm diameter under triaxial compression. A transient amorphous phase first forms at the surface and propagates inward around Si-I core, where stress triaxiality is low (shear-dominated). Within the amorphous shell, the material recrystallizes into Si-V at locatio…

In search of constitutive conditions in isotropic hyperelasticity: polyconvexity versus true-stress-true-strain monotonicity
The polyconvexity of a strain-energy function is nowadays increasingly presented as the ultimate material stability condition for an idealized elastic response. While the mathematical merits of polyconvexity are clearly understood, its mechanical consequences have received less attention. In this contribution we contrast polyconvexity with the recently rediscovered true-stress-true-strain monotonicity (TSTS-M${}^{++}\!$) condition. By way of explicit examples, we show that neither condition by …

Mean velocity profiles and total shear stress profiles in adverse-pressure-gradient turbulent boundary layers considering history effect
This study focuses on developing a predictive model for mean velocity profiles and total shear stress profiles in turbulent boundary layers subjected to adverse pressure gradients, especially with history effects. Based on universal near-wall similarity, a new scaling using friction velocity modified by Clauser pressure gradient parameter is introduced to restore streamwise self-similarity. Furthermore, an estimation-correction model is developed, explicitly incorporating a streamwise derivativ…

Mixed finite element projection methods for the unsteady Brinkman equations
We present $H(\text{div})$-conforming mixed finite element methods for the unsteady Brinkman equations for incompressible single-phase flow with fixed in space porous solid inclusions. We employ a projection scheme with incremental pressure correction, which requires at each time step the solution of a predictor and a projection problem. The predictor problem, which uses a stress-velocity mixed formulation, accounts for the viscous effects, while the projection problem, which is based on a velo…

A hierarchy of blood vessel models, Part II: 3D-3D to 3D-1D and 1D
We propose and analyze a hierarchy of three models of blood perfusion through a tissue surrounding a thin arteriole or venule. Our goal is to rigorously link 3D-3D Darcy--Stokes, 3D-1D Darcy--Poiseuille, and 1D Green's function methods commonly used to model this process. Here in Part II, we consider the most detailed level, a 3D-3D Darcy-Stokes system coupled across the permeable vessel surface by mass conservation and pressure/stress balance conditions. We derive a convergence result between …

Why recycling solar panels is harder than you might think
It's hard work soaking up sunlight to generate clean electricity. After about 25 to 30 years, solar panels wear out. Over the years, heating and cooling cycles stress the materials. Small cracks develop, precipitation corrodes the frame and layers of materials can start to peel apart.

Planning for Cooler Cities: A Multimodal AI Framework for Predicting and Mitigating Urban Heat Stress through Urban Landscape Transformation
As extreme heat events intensify due to climate change and urbanization, cities face increasing challenges in mitigating outdoor heat stress. While traditional physical models such as SOLWEIG and ENVI-met provide detailed assessments of human-perceived heat exposure, their computational demands limit scalability for city-wide planning. In this study, we propose GSM-UTCI, a multimodal deep learning framework designed to predict daytime average Universal Thermal Climate Index (UTCI) at 1-meter hy…

Impact of Geometric Uncertainty on the Computation of Abdominal Aortic Aneurysm Wall Strain
Abdominal aortic aneurysm (AAA) is a life-threatening condition characterized by permanent enlargement of the aorta, often detected incidentally during imaging for unrelated conditions. Current management relies primarily on aneurysm diameter and growth rate, which may not reliably predict patient-specific rupture risk. Computation of AAA wall stress and strain has the potential to improve individualized risk assessment, but these analyses depend on image-derived geometry, which is subject to s…

Helical Locomotion in Yield Stress Fluids
We report three stages for locomotion of a helical swimmer in yield stress fluids. In the first stage, the swimmer must overcome material's yield strain to generate rotational motion. However, exceeding the first threshold is not sufficient for locomotion. Only when the viscous forces are sufficiently strong to plastically deform the material to a finite distance away from the swimmer, net locomotion will occur. Once locomotion is underway in the third stage, the yield stress retards swimming a…

The films were deposited by DC magnetron sputtering on MgO substrate with stress-mediating Cr buffer layer. Structural and magnetic characterization revealed an stress-induced martensitic transformation for the films thicker than 80 nm, while thinner films remained in austenite structure deformed by substrate constrain…

An analytic approach to the stress energy tensor in quantum field theory
We discuss a framework for quantum fields in curved spacetimes that possess a stress energy tensor as a connection one form on a suitable moduli space of metrics. In generic spacetimes the existence of such a tensor is thought to be a replacement for the existence of symmetries that the Minkowski theory relies on. It is shown that the local time-slice property and the implementability of local isometries is a consequence of the existence of a stress energy tensor that is a local field. We prove…

A symbolic regression-based implicit algebraic stress turbulence model: incorporating the production of non-dimensional Reynolds stress deviatoric tensor
Turbulence constitutes an exceptionally complex and irregular flow phenomenon that manifests in liquids, gases, and plasma, making it ubiquitous in both natural processes and engineering applications. Given the relatively modest advancements in classical turbulence models over the past half-century, data-driven approaches, such as machine learning, have recently gained considerable traction in turbulence model research. In this study, we introduce a symbolic regression-based implicit algebraic …

Preparing for the worst: Long-term and short-term weather extremes in resource adequacy assessment
Security of supply is a common and important concern when integrating renewables in net-zero power systems. Extreme weather affects both demand and supply leading to power system stress; in Europe this stress spreads continentally beyond the meteorological root cause. We use an approach based on shadow prices to identify periods of elevated stress called system-defining events and analyse their impact on the power system. By classifying different types of system-defining events, we identify cha…

Confinement geometry governs the impact of external shear stress on active stress-driven flows in microtubule-kinesin active fluids
Active fluids generate internal active stress and exhibit unique responses to external forces such as superfluidity and self-yielding transitions. However, how confinement geometry influences these responses remains poorly understood. Here, we investigate microtubule-kinesin active fluids under external shear stresses in two geometries. In slab-like confinement (a narrow-gap cavity), external stresses propagated throughout the system, leading to stress competition and a kinematic transition tha…

Spreading droplets of yield-stress fluids with and without gravity
We investigate the effect of gravity on the spreading of droplets of yield stress fluids, by performing both microgravity experiments (in a drop tower) and experiments under terrestrial gravity. We investigate the dependence of the final droplet shape on yield stress and gravity. Droplets are deposited on a thin film of the same material, allowing to directly test scaling laws derived from the thin-film equation for viscoplastic fluids. Microgravity conditions allow to vary independently the tw…

Viruses hidden within fungi could be secret drivers of deadly lung infections
Researchers have discovered that a virus living inside the fungus Aspergillus fumigatus significantly boosts the fungus's ability to survive stress and cause severe infections in mammals. Removing the virus made the fungus weaker and less virulent, while antiviral treatments improved survival outcomes. This finding reveals a hidden factor driving the deadliness of fungal infections and opens the door to potential new treatments that target the virus rather than the fungus itself.
