Sensitivity analysis of distance accuracy test for six-degree-of-freedom serial industrial robots

Purpose In recent years, industrial robot technologies and applications have developed rapidly, making it necessary to improve their performance testing methods. This paper aims to investigate the sensitivity of the distance accuracy test method specified in ISO 9283:1998 (Manipu...

Examples of counterexamples: a book conspectus

A counterexample is any exception to a generalization. Counterexamples are often used in science (and philosophy), as a means to setting boundaries. In mathematics at large, well-chosen counterexamples may bound possible theorems, disprove certain conjectures. Recent breakthrough...

Medicinal Herbs in the Management of Hyperlipidemia: A Comprehensive Review

Cardiovascular diseases are the main cause of morbidity and mortality worldwide, with hyperlipidemia being a key risk factor. Conventional hypolipidemic drugs such as statins are effective but often associated with adverse effects, creating demand for safer alternatives. Medicina...

Bittersweet: a multi-method qualitative analysis of Sugar-Sweetened Beverages (SSB) tax discussion in the Nigerian media

Abstract In 2021, the government of late President Muhammad Buhari signed the Finance Act of 2021 into law. This law, through the Customs, Excise, Tariffs, etc. (Consolidation) Act, instituted a ₦10-per-litre tax on Sugar-Sweetened Beverages to reduce excessive added-sugar consum...

The Jacobi-positive squarefree odd semiprimes: a complete parametrisation

Let N = ℓM with 3 ≤ ℓ < M distinct odd primes and let 𝒥(N) be the set of denominators Q_k in the period of the continued fraction of √N whose Jacobi symbol (Q_k/N) equals +1. A previous paper (DOI 10.5281/zenodo.21285697) proved that 𝒥(N) = {1} forces the period length L to lie i...

Standardized method to develop an endometriosis model in Sprague–Dawley rats: A step-by-step description

Objective: To establish a standardized and reproducible rat model of endometriosis by refining the classic Vivian technique, with the aim of minimizing methodological variability and replicating key features of human disease.Methods: Sixty female Sprague–Dawley rats (6 weeks old)...

Hepatic GPR110 plays a complex and context-dependent role in metabolic dysfunction-associated steatotic liver disease

Metabolically-dysfunction-associated steatotic liver disease (MASLD)—formerly known as nonalcoholic fatty liver disease (NAFLD) —is now the most common chronic liver disease worldwide, affecting more than 30% of the global population. Recent studies have documented seemingly cont...

miR172 ‐ AP2 Controls Age‐Dependent Regeneration Competence in Populus

ABSTRACT Plants maintain remarkable regenerative potential, yet this capacity declines with developmental age, limiting clonal propagation and biotechnological applications. Here, we show that the miR172‐AP2 module serves as a central determinant of regeneration competence in Pop...

The ethical reflections of DNA computing researchers and Bernard Stiegler’s philosophy of technology

DNA computing is an interdisciplinary field working at the intersection of computer science, molecular biology and material sciences to develop novel nanobiotechnologies. In this article, I draw on interview data to critically examine the ethical reflections of sixteen researcher...

Age-Dependent Toxicity Patterns in Medulloblastoma: A Comparative Analysis of Treatment-Related Adverse Events Between Pediatric and Adult Populations

Background/Objectives: to compare and characterize the frequency and severity of treatment-related adverse events (TRAEs) experienced by pediatric and adult patients with medulloblastoma receiving the same pediatric-based treatments. Methods: a retrospective comparative study of...

E8 Phi‑Resonant Spin‑Orbit Coupling for Topological Qubit Protection — E8 Intelligence Research

By treating the 240 E8 root vectors as the lattice sites of a magnonic crystal, a coherent 132 Hz φ‑carrier drives a non‑abelian torsional standing wave that locks the spin‑orbit interaction of embedded electron spins into a symmetry‑protected subspace. The resulting phi‑modulate...

OpenAI's Ten Mathematical Advances Fail the Reality Test

Twelve closed SFT disproofs, twelve first-principles replacements, and the cumulative cross-domain evidence that decides between them. This evidence-led successor directly rejects all ten mathematical and theoretical-computer-science advances advertised by OpenAI on 1 August 2026...

Hosting artificial intelligence platforms in financial institutions through cost model based economic and organisational analysis of internal platforms versus managed hyperscale services

Abstract Financial institutions increasingly rely on artificial intelligence to support decision making, automation, fraud detection, and customer engagement. Unlike technology firms, banks are not primarily mandated to develop artificial intelligence platforms as commercial prod...

STGen: A Lightweight Process-Based Testbed for Scalable IoT Protocol Evaluation with Physically Validated Synthetic Sensor and Anomaly Generation

This paper introduces the Sensor Traffic Generator (STGen), a lightweight, pure-software testbed for evaluating IoT application- and transport-layer protocols at scale. Relative to existing software-based IoT evaluation platforms, STGen combines three design decisions that, to th...

A Statistical Evaluation of the Challenges Faced by Nursing Students During Clinical Learning in Two Selected Schools of Health Technology in Enugu State

Nursing students' professional competence is greatly influenced by their clinical learning environment. However, this training phase is frequently accompanied by a number of difficulties that could impede efficient learning and skill development. Understanding the nature and exte...

Rethinking Plasticity in Sponges

What lies behind the extraordinary phenotypic plasticity of sponges? We used this question to conduct a systematic review of how "phenotypic plasticity" is approached in the literature regarding the phylum Porifera. First, we gathered information on what the literature says about...

The Effects of Recalling Health Insurance and Health Care Experiences on Policy Attitudes

Abstract Context: Individuals' attitudes towards health policy are affected in part by their own experiences navigating the health care system. In the United States, this experience is comprised of both interactions with insurance providers and those with care providers. This stu...

Noise reduction in high-density silicon photomultipliers via passive POCl3 doping on trench

Abstract Deep trench isolation (DTI) is indispensable for suppressing crosstalk and enabling high fill factors in dense silicon photomultipliers (SiPMs). However, plasma-induced sidewall defects create interface states that elevate dark count rate (DCR) and afterpulsing (AP) thro...

Hospital Administration as an Emerging Specialty for Medical Graduates in India: A Cross-Sectional Study

Introduction: Most hospitals in India are managed by senior clinicians who are not qualified in hospital administration. The role of qualified hospital administrators does not seem to be highlighted while planning human resources for healthcare services. Postgraduate seats in hos...

A Novel Approach to Characterizing Patterns of Real-World Upper-Extremity Use During Walking and Activities of Daily Living in People with Subacute Stroke
