Toward a Thermodynamic Framework for Dissipative Solitons: From Photonics to Turbulence and Bose–Einstein Condensate Analogies

Thermodynamic concepts are increasingly used in nonlinear photonics to describe Rayleigh–Jeans thermalization, optical wave turbulence, condensation, negative-temperature states, and statistical mode locking. We ask how far this reasoning can be extended to localized structures m...

Financial Management Practices and Health Service Delivery: Evidence from Kenya's Devolved Health System

The aim of this investigation is to examine the relationship between financial management practices, including adherence to budgets, financial monitoring, allocation of financial resources, and financial planning, and health service delivery in the Kenyan devolved health system....

Differentiated inner solar system debris as a major component of some carbonaceous chondrites

Carbonaceous chondrites (CCs) exhibit profound non-systematic heterogeneity in their elemental and isotopic compositions, both within individual meteorite splits and among bulk samples of the same group, providing opportunities for a better understanding of early solar system pro...

morisien-embed: Text Embedding Models and Evaluation for Mauritian Creole (Kreol Morisien)

Second version of the preprint. It describes two released models, morisien-embed and morisien-embed-v1.5; the version number here is the paper's, not a model's. Revision of the first version. The first version reported that a dedicated Mauritian Creole embedding model beat the ge...

Prediction of extreme uncertainty-production events in three-dimensional Navier–Stokes turbulence

We investigate the exponential growth of uncertainty energy in three-dimensional (3-D) Navier–Stokes turbulence, emphasising the intermittent and highly localised amplification/production of uncertainty, a critical factor in understanding the predictability of turbulent systems....

Selection of a Suitable Cartographic Projection for the State Area

Práce si kladla za cíl vytvořit aplikaci, která by usnadňovala výběr kartografického zobrazení pro mapy zvoleného státního území. V teoretické části práce shrnuje řešenou problematiku, věnuje se obecně kartografickému zobrazení a zkreslení, také ovšem možnosti volby zobrazení a h...

Priority Flicker in Risk-Based Pedestrian Prioritization: A Baseline Temporal Stability Assessment on the ETH/UCY Benchmark

Risk-based prioritization frameworks such as the Intelligent Pedestrian Model (IPM) rank pedestrians by an instantaneous, reference-normalized risk score. They indicate which pedestrian requires attention first. This study examines the temporal stability of such rankings. We comp...

Sequential Bromelain-Based Enzymatic Debridement in a Near-Total (97%) TBSA Burn: A Case Report

Introduction: Early debridement of burn eschar is a cornerstone of care for patients with extensive burns, yet early large-area surgical excision may be limited by blood loss, physiological instability, and substantial logistical demands. Evidence on bromelain-based enzymatic deb...

Placenta–Brain Axis Under Heat Stress: Inflammatory Pathways Linking Prenatal Thermal Exposure to Offspring Neurodevelopment

Climate change is increasing the frequency and intensity of extreme heat events, raising concern about prenatal thermal exposure as a potential risk factor for fetal brain development and offspring neurodevelopment. This systematic review aimed to synthesize evidence on prenatal...

Stable and Compact Diagnostic Signatures for Demagnetization-Related Faults in BLDC/PMSM Drives: Evidence from Two Measurement Campaigns

This paper investigates stable and compact diagnostic feature signatures for faults related to demagnetization in brushless direct-current (BLDC) and permanent-magnet synchronous motor (PMSM) drives. Discovery analysis on the public DUDU-BLDC v1 benchmark—where DUDU is the projec...

Uterine Müllerianosis

Introduction: Müllerianosis is a rare pathological entity characterized by ectopic Müllerian-derived tissues, including endometrium, endocervix, and/or endosalpinx. Most reported cases involve the urinary bladder, while uterine involvement is extremely uncommon. We present a case...

Guilt Facets and Eating Disorder Psychopathology: An Exploratory Cross-Sectional Study Using the Moral Orientation Guilt Scale

Background and Objectives: Moral emotions are increasingly implicated in the maintenance of eating disorders (EDs), yet guilt is less differentiated than shame in the ED literature. Contemporary cognitive accounts distinguish deontological guilt linked to violating internalised m...

Modeling and Control Design of Port-Hamiltonian Systems in Discrete-Time

This paper aims to describe a synthesis procedure for discrete-time, energy-based regulators for continuous-time port-Hamiltonian systems. The methodology consists of three steps. The first deals with the definition of a discrete-time approximation of the plant, which is subseque...

From Data Quality to Quality of Agentic Data Use: A Conceptual Framework for Agentic Data Engineering

Large language models and AI agents are extending data-engineering automation beyond isolated artifact generation toward end-to-end processes in which agents interpret requirements, select data, generate transformations, invoke tools, validate results, and communicate analytical...

Objective and Subjective Assessment of the Loudness of Internet Advertisements

Loudness discrepancies between Internet advertisements and the program material they accompany affect user comfort, yet, unlike broadcast television, streaming services are subject to few binding loudness regulations. This article presents a combined objective and subjective expl...

Neural Network-Based Real-Time Wind Energy Estimation

This work proposes a real-time wind power estimation approach for a direct-current (DC) wind energy conversion system based on an artificial neural network (ANN). The proposed ANN uses the Levenberg–Marquardt (LM) algorithm and is trained using experimental data collected from a...

Action-Space-Oriented Reinforcement Learning Compensation for PI-TPS-Controlled Low-Voltage DAB Converters Under Input-Voltage and Load Variations

This study examines how the location of reinforcement-learning (RL) compensation affects the control of a low-voltage dual-active-bridge converter using triple-phase-shift modulation. A proportional–integral triple-phase-shift controller is used as the baseline, and two deep dete...

Particle trapping in vortex crystals

We study the motion of inertial particles in two-dimensional inviscid and viscous vortex crystals, where vortices are placed at the tips of a regular polygon, and determine the conditions under which long-term trapping of particles can occur. In crystals with a central vortex, we...

Comparative performance of ChatGPT-4.0, DeepSeek, Gemini and Perplexity in answering common questions from patients with COPD

Abstract Large language models (LLMs) may help with patient education, but clinicians must check LLM responses for accuracy, comprehensiveness, readability, and safety. This study compared responses from the LLMs ChatGPT-4.0, DeepSeek, Gemini, and Perplexity to 20 English-languag...

The Digital Straw Man: An Audit of Jeremy Heffner's 'Digital Psychopath' Argument

Audit of Jeremy Heffner's HuffPost article 'The Digital Psychopath' (August 3, 2026). v1.2: removed duplicate title on page 1 (TITLE-DUPLICATION-1) — YAML title is the single rendered heading. v1.1 corrected the GPT-5 existence claim (released Aug 7, 2025); the reported interacti...
