Plimpton 322: The Oldest Trigonometric Table, Predating Greek Math by 1000 Years — E8 Intelligence Research

FINDING: Plimpton 322 contains the earliest known trigonometric table based on Pythagorean triples, predating Greek mathematics by over 1000 years. | MATH: Pythagorean triples (a² + b² = c²) generated from reciprocal pairs (x, 1/x) in base-60; ratios like 119/120, 167/169, 319/36...

Geometry-Based Description for Hydrogen Bond Organization in Small Water Clusters Derived from Spectroscopic and Quantum Chemical Data

Hydrogen-bond organization plays a central role in determining the structure and properties of water from molecular to macroscopic scales. In this study, we propose a geometry-based descriptor for small hydrogen-bonded water clusters, (H2O)n, with n = 2–6. The central element of...

Meta-regulator No.4. Regenerative-niche: a system for maintaining tissue homeostasis through stem cells and their microenvironment

A regenerative-niche regulator is a distributed network of local microenvironments (niches) in which a pool of stem and progenitor cells is maintained, ensuring the renewal of body tissues throughout life. It is based on signaling pathways (Wnt, Notch, Shh, BMP, FGF), growth fact...

Young people’s resistance within and against unjust systems: The possibilities and challenges of participatory action research-enabled social innovation and social entrepreneurship

This article establishes a dialogue between the fields of participatory action research, social innovation and social entrepreneurship, by presenting learning from two projects with young people in Colombia and critically situating it within intersectional, intergenerational and...

Seeing Inequalities: Self-Reported Visual Difficulty and Eye Care Utilization Among Women in Malawi, a Secondary Analysis of the 2024 Demographic and Health Survey Data

Background: This study aimed to identify the factors associated with self-reported visual difficulty and uptake of spectacle/contact lens correction among women of reproductive age in Malawi. Methods: We conducted a cross-sectional secondary analysis of the 2024 Malawi Demographi...

The Role of Farmer Field Schools and CGSL Credit Integration in Technology Diffusion in Rural South Sudan

This article examines how Farmer Field School-type extension platforms can be integrated with Community Group Saving and Lending (CGSL) credit mechanisms to accelerate technology diffusion among rural smallholders in South Sudan. The argument is developed from doctoral field evid...

From Missing Data to Conditional Decisions: An Exploratory Pilot on Epistemic Control in Three Large Language Models

This exploratory pilot examines whether large language models can preserve the epistemic status of missing, unknown, hypothetical, and conditional information throughout a decision workflow. The study compared Gemini, ChatGPT, and Claude using a sequence of synthetic decision sce...

The Yield Gap Between Subsistence and Improved Varieties: Estimating Returns to Micro-Credit-Financed Inputs in Eastern Equatoria

This article estimates how micro-credit-financed inputs can narrow the yield gap between subsistence production and improved crop varieties among CGSL-financed smallholders in Eastern Equatoria, South Sudan. The article uses Eastern Equatoria as the focal case within a broader do...

Elastic Constants and Related Properties of Ti4AC3 (A = Si, Au, Ir) MAX Phases: A Comparative First-Principles Study

MAX-phase materials exhibit metallic–ceramic properties. The Ti4AC3 (A = Si, Au, Ir) 413-type MAX phases are investigated here using systematic density functional theory to examine structural stability, elastic behavior, mechanical performance, thermal properties, and electronic...

Human leukocyte extract enhances albendazole efficacy against Echinococcus multilocularis in mice by reducing parasitic microRNAs, myeloid and lymphoid immunosuppressive cells

Background Echinococcus multilocularis induces a serious zoonotic infection in humans and growth of metacestodes is associated with immunosuppression and tolerance. Current treatment relies almost exclusively on albendazole, a parasitostatic drug with variable clinical efficacy....

In Silico Evidence Curation and Pathogenicity Reclassification of MYOD1 Variants of Uncertain Significance in Rhabdomyosarcoma

In pediatric oncogenes, missense Variants of Uncertain Significance (VUS) pose a major challenge in clinical genetics and cancer predisposition screening. MYOD1 encodes a master basic helix-loop-helix (bHLH) transcription factor vital for myogenic differentiation, and specific al...

Sitting with wickedness: negative capability and the practice of despair in and beyond university

Higher education often treats negative emotions as problems to be managed or removed. This paper argues that a wicked problems approach to teaching evokes a distinct emotion, which I term despair, and develops an alternative framework for understanding it. Despair, I argue, is th...

Mapping the landscape of critical failure factors in Lean Six Sigma 4.0 implementation: an ISM–DEMATEL approach

Purpose Lean Six Sigma 4.0 (LSS 4.0) transforms business operations by integrating Lean Six Sigma (LSS) with Industry 4.0 (I4.0), thereby enhancing operational excellence, resilience, sustainability and human factors such as ergonomics and hedonomics. Both developed and developin...

Association between calling and work engagement, and the mediating role of psychological capital and organizational commitment: a structural equation modeling study in China

Abstract Purpose This research aimed to examine the association between calling and work engagement, as well as the mediating roles of psychological capital and organizational commitment. The findings may inform the development of targeted interventions to enhance work engagement...

A process evaluation of a randomized clinical trial of selective decontamination of the digestive tract in ventilated adults admitted to intensive care: the SuDDICU PE study

The SuDDICU trial evaluated the effectiveness of selective digestive decontamination (SDD), a prophylactic antibiotic regimen comprising oral, gastric and intravenous (IV) components in ventilated adults admitted to intensive care. The trial recruited 9289 participants in 26 clus...

Cooperative Event-Triggered Forwarding with Compressed Sensing in Multi-Hop Wireless Sensor Networks

To address the degradation of state estimation accuracy induced by channel fading in multi-hop wireless sensor networks, this paper proposes a novel approach that integrates cooperative communication, compressed sensing and an event-triggered forwarding strategy. By introducing c...

Exposure–Adaptive Capacity Framework for Environmental Chemical Mixtures and Metabolic Resilience: A Critical Review and Operational Proposal

Environmental chemical exposures are increasingly recognized as contributors to metabolic dysfunction, particularly when they occur as chronic, low-dose mixtures rather than as isolated high-dose toxicants. However, current approaches often focus on exposure intensity, single-com...
