Locality in Residuated-Lattice Structures

Many-valued models generalise the structures from classical model theory by defining truth values for a model with an arbitrary algebra. Just as algebraic varieties provide semantics for many non-classical propositional logics, models defined over algebras in a variety provide th...

Unitary quantum matter-bounce in a universe with a positive cosmological constant

Abstract We analyze the Wheeler-DeWitt quantization of a spatially flat Friedmann–Lemaïtre–Robertson–Walker universe containing pressureless dust and a positive cosmological constant ( $$\Lambda &gt; 0$$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mrow> <mml:mi...

Geometry of essential matrix ranges and the Smith–Ward problem for operator systems

Abstract A ‐tuple of bounded linear selfadjoint operators acting on an infinite‐dimensional separable Hilbert space is said to have the Smith–Ward property if the identity map of the image of the operator system in the Calkin algebra has a completely positive lift. In this paper,...

Regime Shifts and Transformations in Social-Ecological Systems: Advancing Critical Frontiers for Safe and Just Futures

Current research challenges in sustainability science require us to consider nonlinear changes—shifts that do not happen gradually but can be sudden and difficult to predict. Central questions are therefore how we can prevent harmful shifts, promote desirable ones, and better ant...

Retail Electricity Costs and Emissions Incentives Are Misaligned for Commercial and Industrial Power Consumers

Abstract Electrification is contributing to substantial growth in U.S. commercial and industrial loads, but the cost and Scope 2 carbon emission implications of this load growth are opaque for both power consumers and utilities. We present a comprehensive spatiotemporal data set...

Centered‐Innovation MA for Bayesian Dirichlet ARMA: Theoretical Equivalence and an Application to Bank‐Asset Shares

ABSTRACT We study a minimal change to an observation‐driven Bayesian Dirichlet ARMA (B–DARMA) for compositional time series: replace the raw additive log‐ratio (ALR) residual in the moving‐average block with a centered innovation that subtracts the Dirichlet conditional ALR mean,...

Conformal network link prediction with false discovery rate control under unstructured missingness

We propose a new method for predicting multiple missing links in partially observed networks while controlling the false discovery rate (FDR), a largely unresolved challenge in network analysis. The main difficulty lies in handling complex dependencies and unknown missing pattern...

Analysis and experiments of the dissipative Twistcar: direction reversal and asymptotic approximations

Abstract Underactuated wheeled vehicles are commonly studied as nonholonomic systems with periodic actuation. Twistcar is a classical example inspired by a riding toy, which has been analyzed using a planar model of a dynamical system with nonholonomic constraints. Most of the pr...

Strong Lead‐Free Bioinspired Piezoceramics for Durable Energy Transducers

ABSTRACT Durable, high‐performance, and environmentally friendly lead‐free piezoceramics are essential for next‐generation sustainable energy transducers and electromechanical systems. However, piezoceramics are mechanically weak, which negatively impacts their working conditions...

Unlocking Scalable Ligand Residence Time Predictions with Koffee Unbinding Kinetics Simulations

A great number of drug discovery programs fail due to poor in vivo efficacy and ADMET liabilities. On- and off-target ligand residence times can act as important drivers of these problems. While modern experimental techniques have made measuring compound kinetics data more routin...

Practitioner psychologists’ experiences of delivering a cognitive behavioural therapy informed crisis intervention for psychosis in inpatient settings: a mixed methods investigation within the CRISIS study

Abstract Objectives Cognitive behaviour therapy for psychosis (CBTp) should be delivered in psychiatric inpatient settings, yet little is known about therapists’ perspectives on delivering it. This study examined therapists’ perspectives on delivering a crisis-focused CBTp-inform...

Constructing Jacobians of rank 1

Abstract Let 𝐾 be a number field, let g ≥ 1 g\geq 1 be an integer and let f ⁢ ( x ) = ( x − a 1 ) ⁢ ⋯ ⁢ ( x − a 2 ⁢ g + 1 ) ∈ O K ⁢ [ x ] see text f(x)=(x-a_{1})\cdots(x-a_{2g+1})\in O_{K}[x] be a polynomial that splits into 2 ⁢ g + 1 2g+1 distinct linear factors. Write 𝐶 for the...

The Star Formation History and Evolution of the Ultra-Diffuse M81 Satellite F8D1

Abstract We present deep Hubble Space Telescope (HST) imaging of one of the nearest ultra-diffuse galaxies (UDGs) outside of the Local Group: F8D1, a satellite of M81 known to be tidally disrupting. UDGs are an enigmatic and diverse population, with evolutionary pathways ranging...

Generation of Polarization-Entangled Bell States in Monolithic Photonic Waveguides by Leveraging Intrinsic Crystal Properties

Advanced photonic quantum technologies -- from quantum key distribution to quantum computing -- require on-chip sources of entangled photons that are both efficient and readily scalable. In this theoretical study, we demonstrate the generation of polarization-entangled Bell state...

Functional Multireference Alignment via Deconvolution

Abstract. This paper studies the multireference alignment (MRA) problem of estimating a signal function from shifted, noisy observations. Our functional formulation reveals a new connection between MRA and deconvolution: the signal can be estimated from second-order statistics vi...

Cosmological constraints from the Planck cluster catalogue with DES shear profiles and Chandra observations

We present cosmological constraints from the PSZ2 cosmological cluster sample, using weak-lensing shear profiles from Dark Energy Survey (DES) data and X-ray observations from the telescope for the mass calibration. We compute hydrostatic mass estimates for all clusters in the PS...

Breaking the Sexual Silence of Cancer Survivors: Exploration of Sexual Distress and Health Communication Paths After Cervical Cancer Surgery Based on Qualitative Interviews

<title>Abstract</title> <bold>Objective</bold> : To better understand the challenges related to sexual function faced by patients with cervical cancer following radical hysterectomy, and to provide evidence-based insights for the development of clinical nursing strategies and hea...

Phase transition in a long-memory log-Gaussian Cox process

We study a stochastic point process with power-law temporal correlations driven by hidden variables. We show that a generalized Merton type model under an exponential-tail asset assumption—obtained by replacing the Gaussian cumulative distribution function with a logistic CDF— to...

Gendered cultural discourse in Japan across the prewar–postwar transition: evidence from historical word embeddings

Abstract We quantify the evolution of gender stereotypes in Japan from 1900 to 1998, covering the prewar–postwar transition, using a series of yearly word embeddings trained on historical text corpora. We define the gender stereotype value to measure the strength of a word’s gend...
