Attachment-line turbulent boundary layer over a swept leading edge at Mach 6: Simulation and flow physics

Direct numerical simulations (DNS) are performed to investigate the spatial evolution of a three-dimensional (3-D) turbulent boundary layer over a swept blunt leading edge at freestream Mach number upper M Subscript normal infinity Baseline equals 6.0 M ∞ = 6.0 $M_\infty =6.0$ an...

Enerzyme: An Efficient Reactive Neural Network Potential Training Framework for Enzyme Cluster Models with Application to Methyltransferases

Abstract Quantum mechanical (QM) cluster models provide an effective framework for mechanistic studies of enzymatic reactions but QM calculations remain computationally demanding. Neural network potentials (NNPs) offer a promising route to reduce their cost, but enzymes introduce...

The acceleration discrepancy is not a universal law of local acceleration: a null-controlled wide-binary test and a three-scale synthesis

We ask whether the mass discrepancy in galaxies, clusters and wide binaries can be described by a single modified law of gravity that depends only on the local acceleration -- the defining property of MOND -- under a strict reproduce-with-control, exact-or-refuse discipline (Yesh...

Soft Dopants for a Soft Lattice: Toward Electronic Doping Control in Metal Halide Perovskite Quantum Dots

Abstract Electronic doping control in semiconductors is essential for engineering optoelectronic properties yet remains elusive for metal halide perovskite quantum dots (MHP QDs). This perspective assesses the current state of aliovalent substitutional doping in MHP QDs and concl...

Libra: A Prototype for Provenance-Aware Fairness Audit Parameters — Implementation Review and Descriptive Sensitivity Analysis

Fairness audits require choices about groups, reference populations, outcome definitions, and decision thresholds. This unreviewed technical preprint presents Libra, a prototype that stores some of those choices with process metadata and applies a selected threshold and reference...

Genetic profile of P. falciparum strains in villages around Soum irrigation Dam, Burkina Faso: insights from targeted sequencing of drug resistance markers in Pfkelch13, Pfubp1, Pfcoronin, Pfcrt, Pfmdr1, Pfdhps and Pfdhfr genes

Abstract Hydro-agricultural settings may sustain high and prolonged malaria transmission and increase antimalarial drug use, potentially intensifying selection pressure on P. falciparum strains. Molecular surveillance in these settings is essential to detect changes in markers as...

Integrative systematics of the Neotropical doryctine wasp genus Panama (Hymenoptera: Braconidae) and related genera with the description of a new genus

Context Panama Marsh (Hymenoptera: Braconidae) is a Neotropical doryctine wasp genus erected to contain a single species, P. canalia Marsh, primarily based on its distinctly extended pronotum forming a pronotal collar. Although several morphologically similar genera also possess...

OMM — Occamian Management Model: A Framework for Simplifying Management, Decision-Making, and Organizational Complexity

This conceptual article introduces the Occamian Management Model (OMM), a proposed managerial framework for diagnosing and reducing unnecessary organizational complexity while preserving complexity that creates value, reduces material risk, enables coordination, improves decision...

Biomass-Assisted Hydrometallurgy and Pyrometallurgy for Sustainable Recovery of Spent Lithium-Ion Battery Cathodes

Abstract Biomass-assisted metallurgy, defined as an umbrella term encompassing recycling technologies that utilize biomass in any form (living microorganisms, biomass-derived chemical compounds, or thermally converted biomass products) as lixiviants, reductants, and/or energy sou...

A Transferable Descriptor for Accurate Prediction of Excitonic Couplings in A-D-A Organic Photovoltaic Acceptors

Abstract Exciton diffusion length (LD) is a key parameter determining the power conversion efficiency of organic solar cells (OSCs), yet its fast and accurate calculation is computationally challenging due to thin-film structural disorder and the long-range nature of excitonic co...

Evolving federated density peak clustering with shuffler-based anonymization

Abstract In this paper, we present a novel one-shot federated clustering approach based on evolving fuzzy clustering and shuffler-based anonymization. In federated clustering, each round reveals additional model information to the server and can increase the opportunity to infer...

Tensor Space and the Causal Limit C: Toward a Dynamic Model of the Universe

This revised research collection presents a reconstructed theoretical framework for investigating whether gravity, time progression, light propagation, motion, and causal transmission can be understood as different manifestations of a common underlying structure of cosmic space....

XAI for AI Auditors: Building a Cost-Effective AI Audit Practice

Research article: XAI for AI Auditors: Building a Cost-Effective AI Audit Practice

The Thermo-Informational Unification Model : Formalization of a Tripartite Topology and Derivation of Mass by Informational Sacrifice.

The attempt to unify quantum mechanics and general relativity remains constrained by the implicit assumption of an exclusively bottom-up causality. This work proposes an alternative architecture based on a closed tripartite topology S=S0+S1+S2 governed by top-down causation. Matt...

Announce, brand, repeat: the illusion of Australian health reform

Health reform announcements can signal progress before improvements in care are demonstrated. Drawing on Baudrillard’s account of sign value, we examine how visible policy achievements can acquire authority independently of clinical benefit. My Health Record illustrates the disti...

Binary Interior Excision and Nonuniqueness of Graph Homology

We give an explicit nonuniqueness example for the (J1, categorical-product) Eilenberg-Steenrod axioms on Cech closure spaces. Applying the known clique and closed neighborhood complex constructions to the mutual singleton graph gives two integral relative homology theories, with...

What the Whole Adds Without Erasing Its Parts: Local Persistence, Overlap, and Relational Completion in Structural Accounts of Experience

What can a whole add while its constituent processes continue, and what evidence identifies that addition? We distinguish process persistence, complete structural preservation, and equality of a local observation. A finite overlap contract separates shared physical occurrences, a...

Algal Bloom Detection and Water Monitoring Using IoT Connectivity

This paper presents an internet-of-things system for algal bloom detection. It relies on microcontrollers, low-cost sensors, the cloud, machine learning, and domain knowledge. An Arduino MKR WiFi 1010 measures pH, temperature, turbidity, and phosphorus (via an RGB sensor and reag...

Why Is There Something Rather Than Nothing?

This paper examines one of the most fundamental questions in philosophy: Why is there something rather than nothing? It is the first paper in a continuing research program developed through the Amirhosseini Cycle (AC), an ongoing effort to investigate foundational questions conce...
