Asymmetric dark matter from low-scale spontaneous leptogenesis

We investigate a novel type of asymmetric dark matter (ADM) model in which the dark matter asymmetry and the baryon asymmetry in our universe (BAU) are produced simultaneously via low-scale spontaneous leptogenesis, where the mass scale of right-handed neutrino is much lower than...

Two decades of conservation agriculture enhances soil structure, carbon sequestration, and water retention in Mediterranean soils

Abstract. Conservation agriculture offers a pathway for enhancing soil health with climate co-benefits in Mediterranean agricultural systems. This study examined long-term impacts of combining no-till management with cover cropping over 20 years in California's Central Valley, pr...

An exact solution algorithm for the bi-level optimization problem of electric vehicles charging station placement

This work addresses electric vehicle (EV) charging station placement through a bi-level optimization model, where the upper-level planner maximizes charging revenue by selecting station locations under budget constraints, while EV users at the lower level choose routes and chargi...

Asymptotic linear dependence and ellipse statistics for multivariate two-sample homogeneity test

Statistical depth, which measures the center-outward rank of a given sample with respect to its underlying distribution, has become a popular and powerful tool in nonparametric inference. In this paper, we investigate the use of statistical depth in multivariate two-sample proble...

Undiscounted Equilibrium in Positive Recursive Absorbing Games with Nonrectangular Absorption Structure

An absorbing game is a stochastic game with a single nonabsorbing state. Such a game is called recursive if all players receive a payoff of zero in the nonabsorbing state and positive if all payoffs in absorbing states are positive. An action profile is nonabsorbing if, when it i...

Quantum metrology of spin sensing with free space electrons

Abstract Recent advances in transmission electron microscopy (TEM) have opened the path toward spin resonance spectroscopy with single-spin sensitivity. To assess this potential, we investigate the quantum precision limits for sensing magnetic moments with free-electron probes. U...

Macmahon-type q-series

Abstract Motivated by earlier work of P. A. MacMahon and recent contributions of T. Amdeberhan, G. E. Andrews, K. Ono, A. Singh, and R. Tauraso on higher-order partition enumerants, we study a class of q -series arising from nested divisor structures. In particular, we consider t...

Autonomous labeling of surgical resection margins using a foundation model

Abstract Assessing resection margins is central to pathological specimen evaluation and has profound implications for patient outcomes. Failure to achieve clear margins significantly increases the risk of local recurrence and may necessitate adjuvant therapies such as chemotherap...

Temporal Dynamics of Complement Activation and Outcome in Patients With Acute Ischemic Stroke

BACKGROUND: Immune-mediated inflammatory responses exacerbate brain injury and affect the prognosis in acute ischemic stroke. METHODS: We characterized longitudinal complement activation after acute ischemic stroke using serial plasma samples from 10 patients and 8 controls. Init...

Ideal optical flux lattices

The realization of fractional quantum Hall (FQH) states in cold atomic gases is a long-standing goal in quantum simulation. Established approaches, including rapidly rotating gases and tight-binding lattices, are often hampered by low interaction energies and small many-body ener...

Quantum chaos diagnostics for non-Hermitian systems from bi-Lanczos Krylov dynamics

In Hermitian systems, Krylov complexity has emerged as a powerful diagnostic of quantum dynamics, capable of distinguishing chaotic from integrable phases, in agreement with established probes such as spectral statistics and out-of-time-order correlators. By contrast, its role in...

A model for mosquito-borne epidemic outbreaks with information-dependent protective behaviour

Abstract We investigate a model for a mosquito-borne epidemic in which human hosts may adopt protective behaviour against vector bites in response to information on both past and current disease prevalence. Assuming that mosquitoes can also feed on non-competent hosts (i.e. hosts...

Characterization of almost Gorenstein rings in terms of the trace ideal

We provide a characterization of one-dimensional almost Gorenstein rings in terms of the trace ideal. As an application, we investigate the almost Gorenstein property of certain ℤ 2 -graded rings.

An ensemble of regional CMIP3/CMIP5 wind wave scenarios for the North Sea and the Baltic Sea: a revisit

Abstract. Storms and associated marine hazards pose a environmental risks, particularly under long-term changes driven by anthropogenic climate change. This study assesses the potential impacts of future climate change on annual median and extreme wave conditions in the North Sea...

An amphibious untethered inchworm soft robot for fast crawling locomotion

Untethered soft robots are essential for advancing the real-world deployment of soft robotic systems in diverse and multitasking environments. Inspired by soft-bodied inchworm, we present a fully untethered soft robot with a curved, flexible structure actuated by magnetic forces....

Macroscopic fluctuation theory from a Lagrangian viewpoint and the Schrödinger problem

We formulate the Schrödinger problem for interacting particle systems in the hydrodynamical regime thus extending the standard setting of independent particles. This involves the large deviations rate function for the empirical measure which is in fact a richer observable than th...

Optimality of Quasi-Monte Carlo Methods and Suboptimality of the Sparse-Grid Gauss–Hermite Rule in Gaussian Sobolev Spaces

Abstract. Optimality of several quasi-Monte Carlo methods and suboptimality of the sparse-grid quadrature based on the univariate Gauss–Hermite rule are proved in the Sobolev spaces of mixed dominating smoothness of order [Formula: see text], where the optimality is in the sense...

First observation of dispersive shock waves in an electron beam

Dispersive shock waves (DSWs) are expanding nonlinear wave trains that arise when dispersion regularizes a steepening front, a phenomenon observed in fluids, plasmas, optics, and superfluids. Here we report the first experimental observation of DSWs in an intense electron beam, u...

Role of PANoptosis in cancer: molecular mechanisms and therapeutic insights

Abnormal cell death plays a crucial role in cancer development. Inducing tumor cell death is an important strategy for cancer treatment. Against this backdrop, with the in-depth study of the regulatory mechanisms of cell death, the discovery of interactions existing among pyropto...

FedPoP: federated learning meets proof of participation

Federated learning (FL) offers privacy preserving, distributed machine learning, allowing clients to contribute to a global model without revealing their local data. As models increasingly serve as monetizable digital assets, the ability to prove participation in their training b...
