Who likes tracking? Evidence on institutional feedback in education policy

Education is recognized as a core component of the welfare state, yet we know little about how existing institutional arrangements shape public support for education policies. We test policy feedback theory in compulsory education, a policy domain where empirical evidence is stil...

Stochastic Modeling and Resource Dimensioning of Multi-Cellular Edge Intelligent Systems

Edge intelligence enables the execution of AI inference tasks on computing platforms at the network edge, typically co-located with or near the radio access network rather than in centralized clouds or on mobile devices. This approach is particularly well suited for data analytic...

Latent causal diffusions for single-cell perturbation modeling

Perturbation screens hold the potential to systematically map regulatory processes at single-cell resolution, yet modeling and predicting transcriptome-wide responses to perturbations remains a major computational challenge. Existing methods often underperform simple baselines, f...

Benchmarking Faradaic Efficiency and O2 Quantification during Water Oxidation under Mild Conditions Using a 3D-Printed Cell and Clark Electrode

Abstract Producing green hydrogen via water electrolysis offers a potential pathway for achieving a sustainable energy transition. Despite its potential, it is limited by the sluggish kinetics of OER, which motivates the development of efficient catalysts. In addition, the field...

On the Physical Origins of the Millimeter Fundamental Plane in Active Galactic Nuclei

Abstract Observations of active galactic nuclei have revealed a correlation between millimeter luminosity, X-ray luminosity, and mass, suggesting the emission in each of these bands is powered by a common source. Starting with a set of five general relativistic magnetohydrodynami...

Integral points over number fields: a Clemens complex jigsaw puzzle

Abstract We prove an asymptotic formula for the number of integral points of bounded log anticanonical height on a singular quartic del Pezzo surface over arbitrary number fields, with respect to the largest admissible boundary divisor. The resulting Clemens complex is more compl...

Central charges and vacuum moduli of 2d $\mathcal{N}=(0,4)$ theories from class $\mathcal{S}$

We investigate 2d \mathcal{N}=(0,4) 𝒩 = ( 0 , 4 ) supersymmetric theories obtained from a topologically-twisted reduction of 4d \mathcal{N}=2 𝒩 = 2 class \mathcal{S} 𝒮 theories on a Riemann surface. This study addresses subtle aspects of central charges, unbroken gauge groups, an...

Critical points of degenerate metrics on algebraic varieties: a tale of overparametrization

Abstract We study the critical points over an algebraic variety of an optimization problem defined by a quadratic objective that is degenerate. This scenario arises in machine learning when the dataset size is small with respect to the model, and is typically referred to as overp...

Earlier green-up exacerbates northern vegetation sensitivity to flash drought

Data used to reproduce the results in “Earlier green-up exacerbates northern vegetation sensitivity to flash drought”.

Unraveling the multifaceted relationship between creativity and mental health with longitudinal analyses of genotyped twins

Abstract Existing findings of creativity and mental health associations are inconsistent, partly due to heterogeneous assessment of creativity and mental health. Consequently, basic questions concerning the direction and domain specificity of these associations remain unanswered....

Combining digital and green technologies in regions: How to close the gap with respect to the frontier?

This paper focuses on the combination of green and digital technologies at the regional level. Using patent data, we put forward an original measurement of the regional speed of green-digital (i.e. twin) combination: the temporal distance between the time at which a combination i...

Understanding the assessment of orofacial functions in children and adolescents: Insights from a scoping review

Abstract Background Orofacial dysfunction in children is associated with common conditions such as malocclusion and sleep-disordered breathing. However, variation in what is considered orofacial dys/function in the literature has precluded the development of a robust assessment a...

SAT-sampling for statistical significance testing in sparse contingency tables

Abstract Exact conditional tests for contingency tables require sampling from fibers with fixed margins. Classical Markov basis MCMC is general but often impractical: computing full Markov bases that connect all fibers of a given constraint matrix can be infeasible and the result...

Gut microbial metabolism of peanuts generates immunoregulatory metabolites

Background. Complementary feeding practices and timing are thought to significantly influence early life immune development, with the early introduction of allergenic foods being especially important for prevention of food allergy. We hypothesized that allergen-containing foods s...

Attention-based foundation model for quantum states

We present an attention-based foundation model architecture for learning and predicting quantum states across Hamiltonian parameters, system sizes, and physical systems. Using only basis configurations and physical parameters as inputs, our trained neural network is able to produ...

Towards local and compositional measurements in quantum field theory

A universal framework for the joint measurement of multiple localized observables in quantum field theory satisfying spacetime locality and compositionality is still lacking. We present an approach to the problem that is based on the one hand on the positive formalism, an axiomat...

New Results on the Polyak Stepsize: Tight Convergence Analysis and Universal Function Classes

Abstract. In this paper, we revisit a classical adaptive stepsize strategy for gradient descent: the Polyak stepsize (PolyakGD), originally proposed in Polyak [ USSR Comput. Math. Math. Phys., 9 (1969), pp. 14–29]. We study the convergence behavior of PolyakGD from two perspectiv...

Magnetic control of an exciton–polariton condensate in a van der Waals magnet

Abstract Quasiparticle condensates are among the most striking solid-state manifestations of quantum physics. Coupling macroscopic real-space wavefunctions to additional degrees of freedom, such as the electron spin, would add valuable control knobs for quantum applications. Whil...

Composable logical gate error in approximate quantum error correction: reexamining gate implementations in Gottesman-Kitaev-Preskill codes

Quantifying the accuracy of logical gates is paramount in approximate error correction, where perfect implementations are often unachievable with the available set of physical operations. To this end, we introduce a single scalar quantity we call the (composable) logical gate err...

Spatial and economic prioritization for distributed wind

Abstract. This study investigates how distributed wind (DW) energy could be strategically deployed in areas with elevated energy burdens by analyzing spatial, economic, and demographic factors. We use a set of metrics that incorporate residential and macroeconomic variables, incl...
