Soundboard Fractures in the Bent Side/Cheek Corner of Harpsichords

The following study is the result of an investigation over several years, seriously because the 2025 Eaton fire interfered substantially. It was prompted by a comment in the Jackrail Forum communications by Domenico Statuto regarding an internet publication by Geert Karman (see l...

Benchmark-Driven Selection of AI Can Improve Capabilities of Reasoning Language Models in Epistemology

Abstract Evaluation of reasoning language models gained importance after it was observed that they can combine their existing capabilities into novel traces of intermediate steps before task completion and that the traces can sometimes help them to generalize better than past mod...

Applications and research gaps in quantum natural language processing: a scientometric analysis

Abstract Quantum Natural Language Processing (QNLP) applies quantum computational models to the representation and processing of language, yet its literature remains fragmented, and no prior study treats it as an autonomous object of analysis. This study maps the field by combini...

The clock gene cycle synchronizes circadian metabolic oscillations uniquely in reproductively active Culex pipiens females

Abstract The circadian clock regulates changes in daily metabolite abundance, coordinating animal activity, feeding and rest. The Northern house mosquito, Culex pipiens , also displays seasonal changes between periods of reproductive activity and overwintering diapause, regulated...

Linear relations modulo meager sets

We prove several topological zero-one laws. First, we show that, if a subset $A$ of a Banach space $X$ has the Baire property, then $A$ admits a somewhere dense set of vectors $x \in X$ such that $A+x$ agrees with $A$ modulo meager sets if and only if it is either meager or comea...

Closed-Form Solutions for Temperature-Dependent Suction Stress under Transient Infiltration in Unsaturated Soil: An Application for Stability Analysis of Strip Plate Anchors

Abstract The soil layer up to a certain depth below the ground surface exists in an unsaturated state, where factors such as precipitation, evaporation, and prolonged subsurface heat waves control the state and material properties of soil. The suction stress that contributes to t...

Large Language Models for Code Generation from Multilingual Prompts: A Curated Benchmark and a Study on Code Quality

Large Language Models (LLMs) perform differently on identical tasks when prompted in different languages—a phenomenon known as language bias. Although well-documented for general text generation, the extent to which language bias affects code generation quality and programming co...

Integrated 3D fully kinetic simulation of field-reversed-configuration formation with embedded coils

We present an integrated, three-dimensional, fully kinetic particle-in-cell simulation of field-reversed-configuration (FRC) formation at the device scale. To our knowledge, this is the first fully kinetic model of whole-device FRC formation. The model embeds the drive coils dire...

Thawed Gaussian Ehrenfest dynamics

Ehrenfest dynamics is a widely used mixed quantum-classical approach for nonadiabatic molecular dynamics, whereas thawed Gaussian wavepacket dynamics provides an efficient semiclassical description of adiabatic nuclear quantum dynamics. Here, we describe thawed Gaussian Ehrenfest...

Toward AI-agent-driven particle transport simulations: implementation of AI-assisted workflows for PHITS

Monte Carlo particle transport codes are powerful tools, but their use requires substantial knowledge of input preparation, execution, and result analysis. In this study, we present a code-side strategy for applying existing AI assistants and AI agents to PHITS. Two complementary...

Delayed Arm Retraction Controls the Nonlinear Oscillatory Response of Long-Chain-Branched Polymer Melts

Abstract Long-chain branching profoundly modifies the nonlinear oscillatory response of entangled polymer melts by introducing arm-retraction pathways absent in linear polymers. We present a molecular tube theory that explains the characteristic maximum of the Nonlinearity Index...

Glymphatic system in temporal lobe epilepsy associated with encephalocele

OBJECTIVES: Temporal lobe encephaloceles (ENCs) are underdiagnosed causes of drug-resistant temporal lobe epilepsy (TLE), frequently associated with idiopathic intracranial hypertension (IIH). Emerging evidence suggests glymphatic system dysfunction in both IIH and TLE. We invest...

Carboxypeptidase activity drives L,D-transpeptidase essentiality during vegetative growth and sporulation in Clostridioides difficile

ABSTRACT In most bacteria, peptidoglycan contains mainly 4-3 crosslinks formed by penicillin-binding proteins (PBPs). However, in the opportunistic pathogen Clostridioides difficile , 70% of the crosslinks are 3-3 crosslinks formed by L,D-transpeptidases (LDTs), and LDTs are esse...

A harmonically coupled-anharmonic-oscillator approach for polyatomic chemistry modeling in DSMC

Atmospheric entry processes are characterized by high-enthalpy gas flows in strong thermo-chemical non-equilibrium. Accurate simulations of such conditions remain challenging due to the extreme conditions and the complex influence of internal energy modes. In particular, the comm...

Cosmic Data Rendering: The Impact of Quantum Entanglement at the Black Hole Boundary on the Expansion of De Sitter Space v3.0

While modern holographic cosmology has been successfully demonstrated in Anti-de Sitter (AdS) space, it faces a fundamental challenge in the realistic De Sitter (dS) space—which possesses a positive cosmological constant and exhibits accelerated expansion—due to the inability to...

Development and Analytical Validation of a Smartphone‐Based Quantitative Lateral Flow Immunoassay for Serum Cystatin‐C

ABSTRACT Background Cystatin‐C is an important renal function biomarker, but conventional quantification requires centralized laboratory analyzers, limiting timely testing in primary care and resource‐limited settings. Methods We developed and validated a quantitative smartphone‐...

A Topological Framework for Finite Behavioural Observations and Verification

Formal verification and monitorability are based on finite observations, which allow properties to be verified from finite information about system behaviour. We study such observations through the topologies they generate on spaces of processes. We first consider trace-based top...

Hysteresis-driven radiative Mpemba effect in phase-change nanostructures

The Mpemba effect states that initially hotter systems cool faster than colder ones. While known in convective, conductive, and quantum systems, its radiative analog is unexplored. Here, this anomaly is realized via phase-change hysteresis of a VO 2 nanoparticle near a SiC substr...

Efficient septum formation is essential for chromosome segregation in Bacillus subtilis when SMC function is impaired

ABSTRACT Structural maintenance of chromosomes (SMC) complexes play conserved roles in chromosome organization, segregation, and repair in all domains of life. In Bacillus subtilis , SMC is required for the segregation of newly replicated origins. To investigate whether other pro...

Visual cue properties determine innate orientation strategy in Monarch butterflies

Animals use a wide range of environmental signals, including celestial and terrestrial cues for navigation. While celestial cues, such as the sun, play a major role in maintaining a constant heading during long-distance migration and dispersal, terrestrial cues provide an animal...
