Militarization, Hindu Nationalist Legitimacy, and Majoritarian Politics in Modi’s India

The relationship between religion, nationalism, and political violence is shaped through direct acts of conflict as well as through the security discourses, institutions, and symbolic practices that define who belongs to the nation and who is represented as a threat. Militarizati...

Super Twisting Observer-Based Fast Terminal Sliding Mode Control with Dual-Term Hyperbolic Reaching Law: Experimental Validation on Buck Converter

This paper proposes a super twisting observer-based fast terminal sliding mode control scheme with a novel dual-term reaching law for output voltage regulation of a DC–DC buck converter under disturbances. The proposed reaching law replaces the discontinuous sign function with a...

Hydrate-Based Carbon Dioxide Sequestration in the Black Sea: Implications for Turkiye’s Exclusive Economic Zone

Abstract This study evaluates the potential for hydrate-based carbon dioxide (CO2) sequestration within Türkiye’s Exclusive Economic Zone (EEZ) in the Black Sea by mapping the CO2 Hydrate Stability Zone (CHSZ) and estimating storage capacities under different pore-water salinity...

Systematic Review of the Global Patterns and Determinants of International Student Mobility

ABSTRACT This systematic literature review synthesizes and analyses a corpus of 140 studies on the size and flows of international student mobility (ISM), as well as its determinants. The review confirms a consistent global increase in international students, albeit experienced d...

Seasonality and functional traits of periphytic algae shape zooperiphyton colonization

Abstract We investigated the influence of seasonality and the phycoperiphyton on the colonization dynamics of zooperiphyton on artificial polyethylene terephthalate substrates in a tropical hypereutrophic reservoir. We tested the hypothesis that seasonal climatic conditions drive...

Current and Future Directions for Responsible Quantum Technologies: A ResQT Community Perspective

Abstract Quantum technologies (QT) are advancing rapidly, promising advancements across a wide spectrum of applications but also raising significant ethical, societal, and geopolitical impacts, including dual-use capabilities, varying levels of access, and impending quantum divid...

Nitrous oxide and methane concentrations and air-sea fluxes in undersampled areas of the Mediterranean basin

Abstract. Nitrous oxide (N2O) and methane (CH4) are potent greenhouse gases for which oceanic contributions remain uncertain, particularly in undersampled regions like the Southwest and Southeast margins of the Mediterranean Sea, where there is a major observational gap. This dat...

Google trends analysis of emerging tobacco and nicotine products in countries with the highest tobacco production and marketing between 2015 and 2024

Tobacco use remains one of the leading global public health threats. In recent years, emerging nicotine products—particularly electronic cigarettes and heated tobacco products—have attracted growing attention. Monitoring online search behaviour provides timely insights into publi...

To Measure Is to Exercise Sovereignty: The Impact of Metrology Infrastructure on Technological Sovereignty and the National Economy

This study examines the strategic role of metrology infrastructure and national measurement systems in technological sovereignty, economic development, and social welfare. It argues that the ability to manufacture advanced technologies is not sufficient on its own: countries must...

Experimental and data-driven modeling based analysis of upstream wall-proximity effects on the performance of propellers for multirotor UAVs

The present study investigates the influence of upstream wall proximity on thrust and efficiency in multirotor UAV systems through a combination of experimental measurements and data-driven artificial neural network (ANN) based modeling approaches. Experiments are conducted using...

From Physics to Measurement, from Measurement to Health Technology, and from Health Technology to Social Benefit : A Country That Can Measure Is a Society That Can Improve

This publication explores the interdisciplinary pathway through which physics is transformed into reliable measurement, measurement enables the development and validation of health technologies, and health technologies generate economic and social value. Drawing on examples from...

Optimization of fermentation parameters for the valorization of tomato pomace into biomass to produce single cell protein using Saccharomyces cerevisiae

Tomato pomace, a byproduct of tomato processing industry, can be utilized through fermentation to produce single cell protein (SCP). In this study, fermentation parameters were optimized in a 3-L bioreactor using a full factorial design (FFD), to which a second order polynomial r...

Uncertainty propagation and its impact on earth-fill dam failures

Dam failures represent a significant hazard to downstream, particularly when combined with extreme hydrological inputs and uncertainties in breach development. In this study, a comprehensive hydrological and dam breach modeling framework was applied to the Kanlikoy Dam in Cyprus....

Human Skills in the Age of AI: The Value of Being Human in a World Where Intelligence Is Becoming Cheap

Artificial intelligence is rapidly reducing the cost of accessing information, generating content, analysing data, and performing a growing range of cognitive tasks. This transformation raises a fundamental question: if intelligence-like capabilities become increasingly abundant...

Design and Annual Performance Assessment of A Line-Focus Fresnel Lens Solar Collector Under Local Solar Conditions

Abstract A large share of global energy demand is the heat demand. In Türkiye, a significant portion of this demand originates from low and medium-temperature industrial applications. For reducing CO2 emissions, it is important to use solar thermal systems to meet the industrial...

Temporal dynamics of numerosity judgments: Liberal responses across different reference numbers in early response onsets

Approximate numerosity judgments allow humans and animals to quickly estimate quantities without verbal processing. This ability obeys Weber's law, which states that the discrimination between two quantities depends on their ratio rather than their absolute difference, making num...

Artificial Intelligence–Assisted Scientific Discovery and the Changing Role of the Researcher: Scientific, Social, Economic and Geopolitical Implications for the Twenty-First Century

This conceptual review examines how artificial intelligence is transforming scientific discovery and redefining the role of researchers in the twenty-first century. Rather than viewing AI merely as a computational tool, the paper argues that it is becoming part of a broader scien...

Science Education as Strategic Infrastructure: A Comparative Analysis of the United States, the European Union, England, Japan, and South Korea

This study presents a comparative analysis of science education policies and practices in the United States, the European Union, England, Japan, and South Korea. Rather than comparing student achievement alone, the paper examines how different education systems conceptualize the...

Revisiting the Research–Practice Divide: Teacher Agency, Institutional Conditions, and Practitioner Inquiry in EFL Contexts

The gap between the rhetoric of teacher-as-researcher and the daily reality of the classroom remains a significant chasm in English Language Teaching. While modern policy discourses frequently frame the EFL teacher as a proactive ‘knowledge producer’, the lived experiences of pra...
