A Client-Side, Browser-Native Pipeline for Liveness-Gated Facial Verification and Geofenced Attendance in a Government Internship Setting: Multi-Signal Passive Fusion, Server-Side Verification, and a Post-Defense Security Hardening Case Study

This paper is a post-defense revision of a Design Science Research (DSR) study on a browser-native, client-side, layered verification pipeline built as an individual contribution within a larger Capstone attendance-monitoring system for the Directorate General of Customs and Exci...

Bats of a remote island: integrated genetic and bioacoustics monitoring confirms species occurrence in Flores (Azores, Portugal)

Abstract. Island ecosystems often harbour unique and vulnerable species, yet many remain poorly documented. In the Azores archipelago, two extant bat species are known to occur: the endemic Nyctalus azoreum and the Macaronesian endemic Pipistrellus maderensis. On Flores Island, p...

The Great Pyramid of Giza: A Forensic Engineering Analysis of Construction Methods

This technecial memorandum presents a forensic engineering examination of the construction of the Great Pyramid of Giza. It evaluated the surviving structure as physical evidence and examines construction requirements involving geometry and dimensional control, structural behavio...

Determinacy Is Not Emergence: Clarifying Dynamical Indeterminism, Causal Emergence, and Probabilistic Futures

Three ideas are often discussed in neighboring vocabularies but answer different questions: whether a physical theory is dynamically deterministic, whether a system exhibits causal emergence across scales, and whether an observer should represent the future probabilistically. Thi...

Distinct miRNA expression patterns in circulating eosinophil subtypes and their subtype-derived exosomes in allergic asthma

BACKGROUND: Lung-resident (rEos) and inflammatory (iEos) eosinophil subtypes were initially characterized in mouse models of asthma and have been proposed to contribute differentially to inflammation and remodeling in human allergic asthma (AA). While microRNAs (miRNAs) and their...

Physics GNN Symbolic Discovery: A Self-Auditing Graph Neural Network for Classical Mechanics

This paper studies a deliberately closed testbed for scientific relation discovery. Classical mechanics is encoded as a typed graph with 159 quantity nodes, 131 equation nodes, and 15 law nodes, and an operator-conditioned graph attention network is trained to infer hidden quanti...

Energy-Neutral Exact-Local Cascade Control in a Three-Dimensional Spectral Flow Solver

This study introduces the EIDOS Energy-Neutral Exact-Local Cascade (EN-ELC), a numerical spectral-feedback operator designed to alter resolved interscale energy transfer without directly adding net instantaneous kinetic-energy power to the fluid as a whole. The method is implemen...

Pull: Lazy Materialization of Working Memory for Stateful LLM Conversations

As LLM conversations grow to hundreds of turns, full-context injection incurs O(N²) cumulative token costs, while lossy summarization or hard truncation irreversibly discards historical state. We propose Pull, a session router that maintains an addressable metadata directory via...

Discrepancies between estimated and geometrically derived mechanical power in invasively ventilated patients – insights from a randomized clinical trial

Abstract Background Mechanical power (MP) quantifies the energy transferred from the ventilator to the respiratory system and is increasingly linked to outcomes in invasively ventilated critically ill patients. Limiting MP may support lung-protective ventilation by integrating ke...

CycloneSEQ S1 system UHRR demo data

The UHRR reference standard data obtained using the S1 sequencing system on the CycloneSEQ G400-ER nanopore sequencing platform are provided for reference.

Adaptation, Not Priming: A Repulsive In-Context Aftereffect Carried by a Sparse Set of Attention Heads

In-context learning is assumed to assimilate: repeated exposure pulls the next prediction toward the repeated pattern, as induction and copy mechanisms attest. We report the opposite sign for graded scalar attributes, and establish three things about it. The phenomenon. Across fi...

Optimization of Geometric Parameters in Moon Texturing to Enhance the Tribological Performance of AISI 5115 Steel

Abstract Surface texturing can significantly enhance the tribological performance of materials. In this study, a novel moon-shaped surface texture was designed and optimized via computational fluid dynamics (CFD) simulations. The optimal geometric parameters were identified as R...

A Wastewater-basedModeling Framework for InferringNorovirus Transmission Dynamics

Abstract Norovirus is a leading cause of gastroenteritis globally, yet its true infection burden in the community remains poorly understood because of widespread asymptomatic transmission and underreporting. Wastewater-based surveillance is a promising approach for tracking infec...

Perimenstrual repetitive greater occipital nerve blockade for menstrual migraine: a randomized, double-blind, placebo-controlled trial

Abstract Background The main purpose of this study is to demonstrate the decrease in headache severity, pain duration and the number of painful days in a month after repetitive GON blockade applied with local anesthetic in menstrual migraine patients compared to the placebo group...

GPR132 antagonists alleviate atherosclerosis by suppressing M1 polarization and subsequent VSMCs proliferation and migration as revealed by transcriptomic profiling

BACKGROUND: Atherosclerosis (AS) is a chronic inflammatory disorder with substantial global prevalence, wherein macrophage polarization and vascular smooth muscle cells (VSMCs) phenotypic switching are critical pathogenic events. Although G protein-coupled receptor 132 (GPR132) i...

Self-Adaptive Thermoregulating Coating for All-Weather Thermal Management

Practical thermal management of functional interfaces usually requires coordinated solar absorption and radiative heat dissipation under variable environmental conditions. Yet, conventional photothermal systems maintain static spectral responses and fail to adapt to dynamic therm...

Diagnostic accuracy of single-, tri-, and four-phasic CT urography and radiation dose assessment: a systematic review and meta-analysis

Abstract Background Computed tomography urography (CTU) is widely used for evaluating urinary tract disorders, but the optimal number of acquisition phases remains uncertain because additional phases increase radiation exposure. This study aimed to evaluate the diagnostic accurac...

Effects of small-scale forest treatments on reducing wildfire burn severity

Background Intensive fire suppression and climate change have escalated wildfire intensity in fire-adapted forests. Although the consequences of fire suppression policies are well documented, fuel reduction treatment effectiveness – particularly across varying treatment sizes – r...

Transcriptomic Alterations and RNA-Seq Computational Workflows in Space Biology: A Review of NASA Open Science Frameworks

Biological systems exposed to spaceflight environments encounter unique physical stressors, primarily microgravity and ionizing cosmic radiation. Understanding how these factors influence cellular function at the molecular level requires high-throughput sequencing technologies. T...

Verification-Conditioned Abstention: Withholding Unverifiable Claims in Labor-Market Decision Support

Selective prediction, learning to defer, and conformal methods all condition the decision to abstain on the model’s estimate of its own correctness. We define and deploy an alternative. In verification-conditioned abstention the selection function is a decidable predicate over an...
