The Fibonacci Rectangle Game: Two First-Move Classes and a Triangle-Induced Choice

A square-adjoining rectangle game generates the Fibonacci numbers and the Fibonacci spiral from a simple geometric rule. If one starts from a square, the four possible first moves are all equivalent by rotation. If one starts instead from a non-square rectangle, there are still f...

Thickness-dependent crack suppression and wrinkle formation in freestanding BaTiO3 membranes

Freestanding ferroelectric oxide membranes offer a promising route toward silicon-integrated low-power electronic and memory devices, but reproducible membrane quality remains challenging, particularly in ultrathin BaTiO 3 (BTO), where cracking and wrinkling hinder integration. H...

Practical Approaches to Performance Warranties for Wind Turbine Blade Heating Systems

As de-icing and anti-icing blade heating systems for wind turbines continue to mature, operators have developed a clearer understanding of both their benefits and their limitations. This growing operational experience has increased the need for warranty frameworks that can verify...

The UV-IR Bridge in Gravity: (ver 1.1.2) A Self-Consistent, Resolution-Dependent Backreaction and Interscale-Descent Framework

This preprint (v.1.1.2) develops a resolution-dependent framework for analyzing how effective gravitational descriptions relate across microscopic and macroscopic scales. Rather than treating gravity’s microscopic weakness and macroscopic dominance as consequences of a single sca...

Benchmarking Large Language Models on Long-Tail Plant Taxonomic Knowledge with PTTB-600

Plant taxonomic knowledge contains a long tail of infrequently encountered names, diagnostic characters, and nomenclatural decisions, yet model reliability across this distribution remains unclear. We developed the Chinese-language PTTB-600, comprising 200 general, 300 ordinary s...

Noncollinear kagome magnet driven by giant antisymmetric exchange

Kagome lattices host exotic phenomena such as quantum spin liquids, topological Weyl nodes, and flat bands. The kagome ferromagnet Co3Sn2S2 has been a focus of debate due to conflicting reports on its magnetic character. Here, using weakly perturbative probes—primarily neutron sc...

Paradigm Shift in Wildfire and Large Vertical Urban Structure Management: Three-Dimensional Vision and Convective Plume Abatement

ABSTRACT Traditional wildfire suppression and high-rise structural firefighting remain fundamentally constrained by a two-dimensional mass-impact paradigm: delivering large, compact volumes of water directly onto burning solid fuel. This operational doctrine omits the primary the...

The Brand Fact Error Rate: Study Protocol, First Edition

Pre-registered study protocol. This record contains no results. Commercial measurement of brand presence in AI assistants reports whether an engine mentions, cites or recommends a brand. This protocol measures a different property: whether the factual statements an engine makes a...

Can Urban Planners Rely on Large Language Models? An Exploratory Evaluation of Four Frontier Models on Two Contested Greek Masterplans

Urban planners are increasingly using Large Language Models (LLMs) to draft project appraisals, raising the question of whether such systems can act as independent evaluators. Here we test this question on two contested urban regeneration projects in Greece: Hellinikon in Athens...

Trisduction System Role: The Kinetic Preloader and the RAM-Founded Computational Kernel

This document delivers the Trisduction and MathDuction Unified Master System Role as a single load-ready artifact. The role is a verification architecture, not a content generator: pasted into any sufficiently capable AI substrate as its system instruction, it converts that subst...

Estimation of the laser guide star uplink tip-tilt using aperture size diversity

Laser guide star (LGS) adaptive optics cannot directly measure tip-tilt (TT), forcing reliance on natural guide stars and limiting sky coverage. We propose estimating the uplink TT from telemetry acquired at the laser launch telescope alone, operated in a monostatic configuration...

Rational design of short hybrid Cecropin B/Aurein 1.2 peptide analogues: in vitro synergistic anti-MRSA and anti-biofilm activities

Abstract Background The increasing prevalence of methicillin-resistant Staphylococcus aureus (MRSA) and the limited efficacy of conventional antibiotics necessitate the development of novel antimicrobial agents. This study aimed to design short hybrid antimicrobial peptides deriv...

Burnout syndrome, sleep quality and the effect of the practice of physical activities among community pharmacists in Douala, Cameroon: a cross-sectional study

Abstract Background Burnout is a human psychological response to work stress, evolving more prevalent among healthcare professionals and associated with many contributing factors. Aim The present study aimed to determine burnout prevalence and its associations with physical activ...

Unveiling the Productivity Potential of Vertical Farming Through Diverse Crop Cultivation: An Empirical Analysis

While vertical farming may offer high productivity per unit land area and has received increasing attention for urban food production, research has primarily focused on leafy greens and herbs. Although recent studies have also introduced fruiting vegetables and cereal crops, comp...

Loss of salt iodization harmed child survival and academic achievement in Ethiopia

Abstract The introduction of salt iodization is associated with improved health and socioeconomic outcomes, but is not yet universally adopted and not always sustained. Using a quasi-experimental event study with difference-in-differences over space and time, we quantify the impa...

Fast and Interpretable Estimation of Amino Acid Residue Surface Accessibility Based on Protein Contact Graph

Relevance. The solvent accessible surface area (SASA) of amino acid residues is a key characteristic for protein structure analysis, but precise methods for calculating it (e.g., FreeSASA) are computationally expensive. Empirical approximations based on the res-idue interaction n...

State-Averaged Density Matrix Embedding Theory for Local Excitations

Abstract Density matrix embedding theory (DMET) provides an elegant framework in quantum chemistry to describe local properties of chemical systems, which allows a high-level method to solve an embedded subsystem constructed based on a low-level treatment of the whole system and...

Impact of wildfires on the soil microbiome and soil biogeochemical parameters: A systematic review

This registration contains the protocol for a systematic review evaluating the effects of wildfires on soil bacterial and fungal communities and soil biogeochemical parameters across ecosystem types, fire-severity levels, and postfire assessment periods. The protocol is made publ...

An Equity-Driven Analysis of the Implications of Attachment and Attachment Readiness Within Primary Care Healthcare Systems in Canada

Background: The persistent challenge of not having a physician or nurse practitioner for ongoing care for millions of residents imposes a burden on the health economy in Canada and demands a shift in focus from mere system registry to the value-based concept of attachment readine...

Beyond Net Metering: Design and Performance of a Hybrid Solar Strategy for Cost Efficiency and Security of Supply in Intermittent Urban Grids

Distributed generation offers a critical pathway to sustainable urban energy; however, incomplete regulatory frameworks in emerging economies frequently force residential photovoltaic (PV) systems into export-restricted operation. This study quantifies the empirical performance a...
