Energy Trade and Welfare Effects of the 2025 US–China Tariff Shocks: A Recursively Updated GTAP Analysis

The 2025 tariff escalation between the United States (US) and China generated uneven macroeconomic and energy-trade effects. Using a Global Trade Analysis Project (GTAP) model updated recursively to a common 2023 benchmark, we analyze five independent cumulative-tariff scenarios,...

Effect of Magnetic Field Orientation on Thermal Conductivity in FeNi2 Alloys

Objectives: This study aims to quantify how the orientation of an external magnetic field influences the thermal conductivity of FeNi₂ (permalloy) alloys. Method: This study used a multiscale approach combining LAMMPS spin-lattice dynamics simulations and analytical calculations...

Direct Silicon/Perovskite Heterojunction Solar Cells Enabled by Interfacial Energetics and Charge-Selective Contact Engineering

Abstract Single-junction crystalline silicon (Si) and perovskite solar cells are approaching their fundamental efficiency limits, while the prevailing Si/perovskite tandem architecture requires complex sub-cell interconnection and current matching. Here, we developed a Si/perovsk...

Ethnobotanical Knowledge and Traditional Uses of Griffonia simplicifolia (DC.) Baill. (Fabaceae) in Togo: Focus on Seed Oil

Background and objective. Griffonia simplicifolia is a woody vine found in the secondary forests of West and Central Africa. Its seeds are an important source of 5-hydroxytryptophan (5-HTP), a precursor of serotonin, and contain an oil rich in linoleic acid. Traditional knowledge...

A systematic and critical review of fractional order models in infectious disease dynamics

Abstract Fractional-order models have become increasingly relevant in infectious disease epidemiology for characterizing transmission dynamics, capturing memory effects, and evaluating intervention strategies. This study presents a systematic and critical review of fractional-ord...

Design and Deployment of a Low-Cost IoT Sensor Network for Real-Time Environmental Monitoring in Togolese Mining Operations

{ "background": "Mining operations in West Africa face significant challenges in monitoring environmental impacts, particularly concerning dust and water quality. Conventional monitoring systems are often cost-prohibitive and lack real-time data capabilities, leading to reactive...

Selective Disruption of Linearization in Non-Speaking Autism: A Cortico-Striatal Account and a Direct Test of the Comprehension–Expression Dissociation

Non-speaking autistic individuals (nsASD) frequently present with a receptive–expressive discrepancy: a subgroup comprehends hierarchically structured language while producing little or no ordered multi-symbol output, across speech, gesture, and augmentative and alternative commu...
