Fracture behavior in Charpy impact tests of wire arc additively manufactured (WAAM) carbon steel wall components

Abstract This study aims to clarify the challenges associated with applying conventional fracture evaluation methods to wire arc additive manufactured (WAAM) carbon steel components. Charpy impact tests were conducted on wall components fabricated using four types of carbon steel...

Non-negative Positionality in Regular Abstract Numeration Systems: Balance-Loop Normal Forms and Infinite Integer Viability

This paper develops an exact normal form for the nonnegative positionality problem in regular abstract numeration systems. A companion paper showed that, after an effectively computable finite preperiod and periodic phase lift, affine positionality is governed by a finite homogen...

I Meet My Needs at Their Price, Never at the Cost of My Dignity

This record documents the original personal motto authored by Hassan Hijazi: “I meet my needs at their price, never at the cost of my dignity.” The phrase expresses a personal principle of self-reliance, dignity, and fair exchange: needs should be met through their appropriate pr...

An Evidence-Level Framework for Evaluating Enzyme-Mediated Plastic and Microplastic Transformation

Microbial enzymes have attracted considerable attention as biocatalysts for plastic transformation, yet the experimental evidence supporting reported biodegradation varies substantially in quality and interpretation. Surface-sensitive techniques, molecular-weight analyses, identi...

LAB #1028 NEUTRAL: TG AUTO: BASE 44 ORDER: Build breakthrough_e8_cache table and E8 hash function with LLM caching — E8 Intelligence Research

IDEA: AUTO-FORWARDED from the Telegram/breakthrough stream (#646569, division=platform, agent=andrew_base44): Andrew's order (Base 44 console): [SELF-BUILD from enhancement #1100] Create `breakthrough_e8_cache` table with columns specified. Implement Python E8 hash function using...

Critical Line Convexity: The Zeta-Gravity Metric and Geometric Structure of Zeta Zero Loci 临界线凸性与 ζ 引力度规:黎曼 ζ 函数的算术几何场理论

Abstract This paper puts forward a novel geometric framework centered on the Zeta-Gravity Metric to systematically investigate the distribution of non-trivial zeros of the Riemann zeta function. Two core discoveries are established: first, the Critical Line Convexity (CLC) proper...

Comparison of the active cycle breathing technique with other self-administered breathing techniques for the management of mucociliary production in cystic fibrosis: A systematic review

Background Cystic fibrosis (CF) is characterized by excessive airway mucus, recurrent infections, impaired ventilation, and progressive decline in lung function. Airway clearance techniques are central to management. Among them is the active cycle of breathing technique (ACBT), w...

Into the Bermuda Triangle: How Prime Ministers Fall

ABSTRACT Eleven years after David Cameron promised ‘stability and strong government’; nine years after Theresa May pledged ‘strong and stable leadership’; and two years after Keir Starmer vowed to ‘stop the chaos’, the UK has its seventh prime minister in a decade. Most analyses...

A Data‐Driven Review of Geoscience Research Evolution Using SciBERT ‐Based Topic and Network Analysis

ABSTRACT This review provides a data‐driven synthesis of the evolution of geoscience research from 2004 to 2023. A field‐level bibliometric overview of 439,680 records indexed in the Web of Science Core Collection (Geosciences, Multidisciplinary) characterises broad publication p...

Clinical Outcomes Following Transition from ICS/LABA to Single-Inhaler Triple Therapy in Patients with Uncontrolled Asthma: A Real-World Cohort Study

Background and Objectives: A considerable proportion of patients with asthma remain inadequately controlled despite treatment with inhaled corticosteroid/long-acting β2-agonist (ICS/LABA) therapy. Single-inhaler triple therapy comprising an inhaled corticosteroid, a long-acting β...

Kinship Terms and Person Address in the English‐Speaking Sri Lankan Tamil Diaspora

ABSTRACT This article examines the impact of migration, globalization and digitalization on the use of nominal address terms in the English‐speaking Sri Lankan Tamil (SLT) diaspora community by undertaking a corpus analysis of English fiction authored by diaspora members with SLT...

Closed-loop blow forming: direct reuse of trimming scrap for new component manufacture

Abstract In this work, the direct reuse of scrap from the addendum region of previously blow-formed aluminium sheets to manufacture smaller components through a secondary forming step was studied. Numerical simulations and experimental tests were conducted to assess the feasibili...

BODIPY-Integrated Porous Materials: Design Principles, Functional Architectures, and Emerging Applications

Abstract The incorporation of functional organic chromophores into porous architectures has emerged as a powerful strategy to bridge molecular photophysics with materials-level performance. Among these, boron-dipyrromethene (BODIPY) derivatives offer a unique combination of stron...

Catalyst-FreeThiol–yne Nucleophilic PhotoclickChemistry

Abstract X-yne nucleophilic addition reactions are essential and powerful tools in a range of synthetic routes for realizing functional and stimuli-responsive materials. Unfortunately, the lack of spatiotemporal control and the requirement for catalyst addition in these reactions...

An open-source FPGA control architecture for solid-state spin-photon interfaces

Scalable quantum networks require quantum interfaces that coherently connect stationary matter qubits with flying photonic qubits. In solid-state defect platforms, such interfaces require coordinated optical excitation, microwave spin control, photon detection, and feedback with...
