Gradient-Based PSLL Minimization for Uniformly Excited Sparse Linear Arrays

In this paper, we apply a gradient descent method to the synthesis of uniformly excited sparse phased arrays. Because the effectiveness of gradient optimization depends heavily on precise Peak Sidelobe Level estimation, we implement a grid-less framework for radiation pattern ana...

Asymptotic Calibration of the BFS Window and Effective Dimension of the Admissible Trajectory

The O25 programme identified the ratio $n_1(q)/q$ as the central open asymptotic variable controlling the finite-size drift of $\bar{\delta}_{\mathrm{pair}}(q)$, and O26–O27 identified the effective dimension $r_{\mathrm{eff}} = d_\rho^2$ of the per-pair covariance operator in $\...

The Executive Access Model (EAM): A Classroom Framework for Understanding Variability in Student Performance

The Executive Access Model (EAM) is an applied instructional framework that translates a constraint based control architecture of human functioning into observable classroom practice. It explains variability in student performance as changes in executive access, defined as the mo...

The Origin and Necessity of the Quantization of the Universe ——The Universe Exists Only in the Present Moment, and the Adjacent Yuanke Transition Is the Origin and Necessity of Quantization

Previous work (Chen, 2026b) established that the universe exists only in thepresent moment (the previous moment is inaccessible, and the next moment hasnot yet arrived), and introduced the concept of Yuanke — a discrete transitionfrom state Uk to Uk+1 that is physically indivisib...

The Law of Two: Why a Relational Ontology Entails Exactly Two — a Theorem of the Hodos Hypothesis, Derived in One Checkable Step

If nothing is what it is in isolation, how many things does it take to be one thing? The Hodos Hypothesis holds that a thing is the pattern of its connections and not its substrate, and that the regress does not halt. This paper argues that the branching factor of that regress is...

Topological–Historical Continuum Mechanics: A Three-Axiom Framework for Finite Deformation, Plasticity, Defects, Memory, Fracture, Contact, Waves, Structural Reduction, and Certified Computation

We construct a unified framework for continuum mechanics from three physical axioms: microscopic ontic definiteness and finite localization, physical reality of the spacetime–vacuum substrate, and persistent causal source–response coupling. Continuum fields are defined through co...

Closing the per-field reduction: collar contraction, the stretched road, and a certified minimax for the complex sin²-algorithm

We prove a per-field periodicity theorem for the complex sin²-algorithm: for every cubic field K of signature (1, 1) and every order of K, with constants γ = 51/50, m₀ = 10, κ = 1 independent of the field and state, the selected greedy orbit of every admissible initial state is e...

SYSTEMIC INTENT & FISCAL FRICTION: A Strategic Risk Architecture Working Paper

The Solution to the Is-Ought Problem based on Critical Rationalism and Evolutionary Theory

This paper solves the is-ought problem on the basis of critical rationalism, the Quine-Duhem thesis, and the value-theoretic part of Bunge’s ontology. It reconstructs the dogmatization of Hume's demand for justification into a barrier thesis. The naturalistic fallacy is identifie...

The Integrative Learning Design Framework Revisited: AI Affordances, Risks, and Guardrails for Learning Experience Design Research and Practice

The Integrative Learning Design (ILD) Framework (Bannan-Ritland, 2003) has informed and supported a quarter-century of design research methodology in education. This paper is authored by the framework's original architect, drawing on more than thirty years in the instructional de...

PAPER-FBT02C: An S-Sector Maintenance Self-Energy Model of Effective Mass

This paper develops a conditional coarse-grained maintenance self-energy model for stable internal configurations in the Fracture–Berry–Tension framework, updated to the current single-carrier geometry of FBT0B and the affine-prequantum closure of FBT02A–FBT02B. The regular six-d...

PAPER-FBT02A: The S-Gate as a Strict Affine Central Charge

We formulate the residual S-sector of the Fracture–Berry–Tension framework as a strict affine central sector while keeping the geometric, Hamiltonian, loop-algebraic, prequantum, Berry, and representation-theoretic layers mathematically distinct. The regular geometric input disti...

Sexual health and relationship training needs of the substance use workforce: findings from a cross-sectional study

People receiving treatment for substance use disorders and those in long-term recovery who have a history of sex and drug-linked behavior are at greater risk of substance use recurrence than those without a history of problematic sexualized drug use. Yet, recovery support service...

The Merchant's Ledger: 5 Ways Ancient Indian Traders Rewrote Karma, Sin, and Salvation

The word Vaishya entered the Rigveda through a single hymn, the Purusha Sukta, that most scholars regard as a comparatively late addition composed to sanction a social hierarchy already forming rather than to originate it, a genuine and important complication to any tidy origin s...

AN UPDATE ON MECHANISTIC MODES, DIAGNOSTIC APPROACH & DECIDE FOR SURGERY/VIV IN EARLY BIOPROSTHETIC VALVE FAILURE; A REVIEW

The use of bioprosthetic heart valves has expanded considerably over the last 20 years, now are contributors of the maximum of valve replacements conducted worldwide. Whereas late structural valve degeneration continues to be the dominant mode of failure further than 10 years, ea...

Six weeks of isometric resistance training led to evidence of corticospinal but not reticulospinal adaptation in previously untrained adult males

Abstract The latest hypothesis regarding the source of enhanced neural activation from resistance training is the reticulospinal rather than the corticospinal tract, based on invasive animal and emerging human data. The present study employed a six-week isometric resistance train...

Possible Sex Differences in the Morphological and Functional Muscle Quality Reflected by Phase Angle: Implications for Muscle Quality Assessment

ABSTRACT Background and Purpose Phase angle (PhA), derived from bioelectrical impedance analysis, is a noninvasive indicator of muscle quality. It is unclear whether PhA better reflects the morphological or functional muscle quality in community‐dwelling older adults, and whether...

Introduction

The United States and China are engaged in what can best be described as a derisking race. Having encouraged their economies to become deeply intertwined, each nation is now attempting to achieve significant separation from the other. Neither side currently seeks to decouple comp...

Social Dynamics in Zoo‐Housed Bush Dogs (Speothos venaticus) Following Group Changes

Bush dogs (Speothos venaticus) are cooperatively breeding South American canids with relatively unstudied behavior. Here, we study a group of zoo-housed bush dogs to investigate the impact of pack structure changes on their collective movements, social hierarchy and social networ...
