J-PAS: Semisupervised Sim-to-Obs Transfer for Robust Star–Galaxy–Quasar Classification

Abstract Modern astrophysics and cosmology increasingly rely on simulations and cross-survey analyses, yet differences in instrumentation, calibration, and modeling introduce distribution mismatches between simulated and observed datasets (domain shift). This occurs when the join...

Revisiting the critical role of stabilized Criegee intermediates (sCIs) in sulfuric acid formation: coupling mechanistic updates with interpretable machine learning

Abstract. Sulfuric acid (H2SO4) is a key driver of atmospheric new particle formation and subsequent growth, playing a critical role in the formation of sulfate aerosols. While stabilized Criegee intermediates (sCIs) are recognized to be one of the free radicals oxidated sulfur d...

Momentum-driven reversible logic accelerates efficient irreversible universal computation

Abstract We present implementations of two physically-embedded computation-universal logical operations using a 2-bit logical unit composed of coupled quantum flux parametrons—Josephson-junction superconducting circuits. To illustrate universality, we investigate NAND gates built...

Shallow Trap States Control Electrical Performance of Amorphous Oxide Semiconductor Thin‐Film Transistors

ABSTRACT The performance of n ‐type amorphous oxide semiconductor thin‐film transistors (TFTs) is controlled by the electronic states near the conduction band mobility edge. Here, the full subgap density of states (DoS) of amorphous InGaZnO (a‐IGZO) TFTs, used in display panels a...

Restoring sparsity in potts machines via mean-field constraints

Abstract Ising machines and related probabilistic hardware have emerged as promising platforms for NP-hard optimization and sampling. However, many practical problems involve constraints that induce dense or all-to-all couplings, undermining scalability and hardware efficiency. W...

On The Structure Of Prime-Detecting Quasimodular Forms In Higher Levels

Craig, van Ittersum, and Ono conjectured that every prime-detecting quasimodular form of level 1 is a quasimodular Eisenstein series. This conjecture was proved by Kane–Krishnamoorthy–Lau and by van Ittersum–Mauth–Ono–Singh independently. However, in higher levels, prime-detectin...

Accountability, Integrity: AI Policy in Public Libraries

As artificial intelligence reshapes both library work and the information environment, public libraries must determine whether or how to engage with AI while maintaining library values. To our knowledge, there exists no published analysis of how American and Canadian public libra...

AD-MERGE 2.0: an integrated assessment of the Nexus among energy transitions, climate impacts, and adaptation responses

Abstract. This paper presents AD-MERGE 2.0, an enhanced integrated assessment model that evaluates reactive (“flow”) and proactive (“stock”) adaptation strategies along with climate mitigation policies. The updated model extends AD-MERGE 1.0 through seven enhancements: (i) includ...

Human learning dynamics during teleoperation of surgical robots

Robot-assisted minimally invasive surgery requires operators to learn precise motor control. In this paper, we examined how task complexity and the human-robot motion scaling ratio affect teleoperation learning in a ring-through-rail task implemented on the da Vinci Research Kit....

Building trait complexes of individual differences: A study with higher education students

Interactions among the cross-domain variables of interests, personality, and perceived abilities were analyzed in a higher education sample (N = 312) from a Portuguese public University consisting of 48.9% female and 51.1% male students, aged between 18 and 30 years, and enrolled...

Asymmetric response of coastal currents to oscillating alongshore wind stress over a coastal bank

Abstract. An asymmetric response of coastal currents to oscillating alongshore wind stress is observed over a coastal bank off the southern coast of Korea. Alongshore currents exhibit consistently larger variability in the western region than in the eastern region. Numerical expe...

Investigation of Antiretroviral Therapy (ART) use and drug resistance characteristics in HIV-positive patients

In recent years, the global increase in drug resistance rates against antiretroviral therapy (ART) regimens has underscored the importance of incorporating HIV drug resistance testing into routine clinical practice and its critical role in treatment success. The aim of this study...

Opposing effects of shared and unshared networks drive species coexistence in intransitive competitive ecosystems

Understanding the mechanisms of species coexistence in intransitive competitive communities, which is generally considered favorable for promoting biodiversity maintenance, has long been a crucial issue in ecology. The role of species dispersal along different pathways in shaping...

Computation-bandwidth-memory trade-offs: a unified paradigm for AI infrastructure

Abstract Large-scale artificial intelligence (AI) models are fundamentally transforming industries and redefining the paradigm of human–machine collaboration. While the technological revolution signals a new era of machine intelligence, the continued scaling of these models has e...

Identifying expanding TCR clonotypes with a longitudinal Bayesian mixture model and their associations with cancer patient prognosis, metastasis-directed therapy, and VJ gene enrichment

MOTIVATION: Examination of T cell receptor (TCR) clonality has become a way of understanding immunologic response to cancer and its interventions in recent years. An aspect of these analyses is determining which receptors expand or contract statistically significantly as a functi...

Evaluating different roughness approaches and infiltration parameters for vegetation-influenced overland flow in hydrological model

Abstract. Accurately simulating overland flow in vegetated landscapes remains a challenge in hydrological modeling due to the complex interactions between vegetation, surface roughness, and soil infiltration. This study evaluates multiple methods for estimating Manning's roughnes...

Grand-Canonical Typicality

Abstract We study how the grand-canonical density matrix arises in macroscopic quantum systems. “Canonical typicality” is the known statement that for a typical wave function $$\Psi $$ Ψ from a micro-canonical energy shell of a quantum system S weakly coupled to a large but finit...

Deformations and Abelian Extensions on Anti-Pre-Jacobi-Jordan Algebras

The underlying algebraic structures of nondegenerate commutative 2-cocycles on Jacobi-Jordan algebras are introduced and are called anti-pre-Jacobi-Jordan algebras. It is proved that they belong to the class of Jacobi-Jordan-admissible algebras. Moreover, it is proved that the ne...

Protocol Development and Implementation for Pediatric Acute Abusive Strangulation at a Tertiary Care Children’s Hospital

Background Strangulation by assault is high-risk and survivors have specific medical and forensic needs. There is no standardized protocol for the evaluation of pediatric victims of acute, abusive, nonfatal strangulation. Aim To develop a pathway and supporting documentation temp...

Analytical Valuation of Vulnerable Derivative Claims with Bilateral Cash Flows under Credit, Funding and Wrong Way Risk

We study the problem of valuing and hedging a vulnerable derivative claim with bilateral cash flows between two counterparties in the presence of asymmetric funding costs, defaults and wrong way risk (WWR). We characterize the pre-default claim value as the solution to a non-line...
