Smoothed Analysis for Learning Concepts with Low Intrinsic Dimension
In traditional models of supervised learning, the goal of a learner-- given examples from an arbitrary joint distribution on $\mathbb{R}^d \times \{\pm 1\}$-- is to output a hypothesis that is competitive (to within $ε$) of the best fitting concept from some class. In order to es...

Abstract Background The use of computed tomography at the early stage of acute appendicitis can lead to overdiagnosis and predispose patients unnecessarily to ionising radiation. Adult Appendicitis Score (AAS) can be used to select patients for imaging. Observation and re-scoring...

Magneto-optical detection of spin-orbit torque vector with first-order Kerr effects
Abstract We present a magneto-optical method for quantifying both components of the spin-orbit torque (SOT) effective field vector h_SO in magnetic thin films that, unlike previous complete-vector magneto-optical schemes relying on quadratic Kerr effects for at least one componen...

Abstract We investigate the effects of trade secret (TS) protection on supplier exclusivity in vertical industrial relations. We show that manufacturers limit their suppliers’ buyer networks under weak TS protection to safeguard sensitive information while encouraging supplier in...

Covert Reciprocals in Indonesian
Abstract: Indonesian reciprocals can be expressed through overt reciprocal markers or covertly, via constructions that are not explicitly reciprocal in form. This study focuses on covert reciprocals, adpoting an analysis grounded in a symmetric event approach, in which reciprocal...

Generalizations of Koga’s version of the Wiener–Ikehara theorem
We establish new versions of the Wiener–Ikehara theorem where only boundary assumptions on the real part of the Laplace transform are imposed. Our results generalize and improve a recent theorem of Koga (2021). As an application, we give a quick Tauberian proof of Blackwell's ren...

On a Rankin–Selberg integral of three Hermitian cusp forms
Abstract Let $$K = \mathbb {Q}(i)$$ K = Q ( i ) . We study the Petersson inner product of a Hermitian Eisenstein series of Siegel type on the unitary group $$U_{5}(K)$$ U 5 ( K ) , diagonally-restricted on $$U_2(K)\times U_2(K)\times U_1(K)$$ U 2 ( K ) × U 2 ( K ) × U 1 ( K ) , a...

Azimuthal Anisotropy From Multimode Waveform Modeling Reveals Layering Within the Antarctica Craton
The isotropic structure of the crust and upper mantle under Antarctica has been constrained by many studies. However, the depth dependence of seismic anisotropy, a powerful tool to characterize deformation and flow, is still poorly known. Here, we modeled three-dimensional (3-D)...

A convex optimization approach to the Lyapunov exponents
Abstract The aim of this paper is to shed more light on some recent ideas about Lyapunov exponents and clarify the formal structures behind these ideas. In particular, we show that the vector of averaged Lyapunov exponents of a smooth measure-preserving dynamical system can be re...

Platycladus orientalis has high ecological and economic value, but the quality of Platycladus orientalis seedlings varies greatly. The original quality grading standard is relatively simple and the grading boundary is not clear. It is of great significance to use the in-situ Elec...

A New Method of Solving the Time-Fractional Mixed Nonlinear Diffusion and Diffusion-Wave Equation
It is well known that meshless methods are effective for solving fractional differential equations on both regular and irregular domains. However, many commonly used basis functions such as Legendre wavelets and B-splines are naturally defined on rectangular domains, which limits...

SBKIM: A Protocol for Semantic Bidirectional AI Matching in Human and Agent Networks
We propose SBKIM (Semantic Bidirectional AI Matching), an open protocol fordetermining semantic compatibility between two parties in natural language,without structured queries, databases or centralised platforms. Unlikeunidirectional retrieval systems, SBKIM requires that both p...

Orthogonal dualities of dynamic stochastic higher spin vertex models, using the Drinfeld twister
Abstract We introduce a new algebraic method to construct duality functions for integrable dynamic models. This method will be implemented on dynamic stochastic higher spin vertex models, where we prove that the resulting duality functions between the dynamic stochastic higher sp...

A biochemical mechanism for Stu2/XMAP215-family microtubule polymerases
Abstract Defining quantitative biochemical mechanisms of microtubule dynamics and regulation is a current challenge. Stu2/XMAP215-family polymerases use tubulin-binding TOG domains to catalyze microtubule growth, but how polymerase activity results from the number and tubulinbind...

Abstract Introduction Tuberculosis (TB) is the leading cause of death due to infectious disease worldwide. Social protection interventions can benefit TB-affected households. We conducted a systematic review and meta-analysis to quantify the effectiveness of social protection on...

Sex-specific associations of the plasma-proteome with incident coronary artery disease
AIMS: The etiology of coronary artery Disease (CAD) appears different for men and women, yet insights into underlying sex-specific biological mechanisms are limited. We integrated genomic and proteomic analyses to investigate sex-specific associations of the plasma-proteome with...

Extended second-order multi-class traffic flow model with the relative drag function
In heterogenous traffic flow the interaction between different vehicle classes play an important role. This article deals with the extension of second order multiclass traffic flow models to accommodate some violation of lane discipline and heterogeneous choice of speeds in a tra...

Mapping the past: dynamic local georeferencing for historical cartography
Georeferencing is crucial for integrating historical and pictorial maps into digital environments, enabling their application in research, education, and public engagement. However, traditional GIS-based georeferencing workflows often fall short when applied to these maps, as glo...

BACKGROUND: Noninvasive quantitative assessment of marrow recovery after curative therapies such as total marrow irradiation (TMI) and bone marrow transplantation (BMT) remain poorly defined, particularly in sickle cell disease (SCD). PURPOSE: To evaluate MRI-derived proton densi...

Abstract Spontaneous epimutations are stochastic gains and losses of cytosine methylation that arise from imperfect maintenance across cell divisions. At CG sites, such epimutations can be inherited across generations in plants and constitute a major source of CG methylation (mCG...
