Evaluating clean energy strategies for national carbon neutrality: An interdisciplinary policy-focused decision framework

This study aims to evaluate and prioritize clean energy strategies to support Türkiye's national carbon neutrality goals. Achieving carbon neutrality requires adopting clean technologies and effective environmental policy tools. This study presents a novel multi-criteria decision...

South Africa and Qatar in Gaza and Beyond: A New Dawn for Transformative Third-Party Intervention?

As geopolitical realignment intensifies conflict and exposes failures in Western-led intervention, space is opening for alternative actors and approaches. Gaza marks a critical juncture as non-Western third-party actors assume prominent roles, raising questions about their interv...

Expanded perlite and bio-based residues for circular low-carbon cementitious materials: a systematic review

The transition to circular and low-carbon construction requires materials that combine resource efficiency, thermal performance, mechanical adequacy, and waste valorization. This review synthesizes 139 studies published between 2010 and 2026 on expanded-perlite and bio-based ceme...

Stress corrosion cracking of 316 L stainless steel in simulated Arabian gulf seawater

Abstract Austenitic stainless steels are widely used in coastal and marine infrastructure for its corrosion resistance, yet failures associated with chloride-induced stress corrosion cracking (SCC) continue to be reported. In this work, the SCC susceptibility of 316L austenitic s...

Flexural-wave shielding in plates through scattering by a curved resonator arrangement

This study considers a thin elastic plate excited by a harmonic point force and coupled to locally resonant mass–spring attachments distributed along two opposing parabolic trajectories. The resulting resonator arrangement redirects part of the incident flexural-wave energy throu...

An electro-thermo-chemo-mechanical coupled computational framework for contact–dissolution corrosion using a phase-field formulation

Metallic contact interfaces in electrical connectors, microelectromechanical systems, and related components are commonly subjected to sustained mechanical loading, electrical conduction, thermal effects, and corrosive environments. The strong coupling between contact constraints...

‘God Gave This Land to Me’: parody, grievability, and settler-colonial semiotics in Nina Paley’s This Land Is Mine

This study employs Multimodal Critical Discourse Analysis through a decolonial lens, used here as an analysis of visual and typographic rather than inclusive of sonic resources, to examine how visual semiotics organise grievability in Nina Paley's animated parody This Land Is Min...

Cheby-FENN: a Chebyshev-enhanced feature expansion neural network for electricity theft detection

Abstract Electricity theft is a major contributor to non-technical losses in power systems, causing substantial financial losses and potentially affecting grid reliability. This paper proposes a lightweight neural network framework that incorporates a third-degree Chebyshev polyn...

Dynamic depth quantum approximate optimization algorithm for solving constrained shortest path problem

Abstract The Quantum Approximate Optimization Algorithm (QAOA) has emerged as a promising approach for solving NP-hard combinatorial optimization problems on noisy intermediate-scale quantum (NISQ) hardware. However, its performance critically depends on the choice of circuit dep...

Bioactive peptides in cancer and inflammation: Mechanisms, model systems and clinical translation

Abstract Background Bioactive peptides (BAPs), derived from both natural and synthetic sources, are increasingly recognized as multifunctional agents with potential roles in the management of cancer and inflammatory conditions, in addition to their well‐established antimicrobial...

Sharing transparently: Caring for trustworthiness in qualitative data analysis in L2 research

Abstract The Open Science (OS) movement promotes transparency across the research process. This study examines how transparently qualitative data analysis is reported in second language (L2) research, where unclear methods can undermine trustworthiness. We conducted a qualitative...

Narrating the Syrian refuge crisis: single story of Aylan Kurdi in divergent media narratives

This study examines how English- and Arabic-language news outlets constructed narratives around the death of Aylan Kurdi during the Syrian refugee crisis. Using a qualitative case study design, four articles from the BBC, The Guardian, Al Jazeera and Al Hadath were analyzed throu...

QuantumCanvas: a multimodal benchmark for learning two-body quantum interactions

Abstract Most molecular and materials machine-learning models fit correlations across whole molecules or crystals rather than learning the quantum interactions between atomic pairs. Yet bonding, charge redistribution, orbital hybridization, and electronic coupling all emerge from...

The abscopal effect and systemic immune reprogramming: from phenomenon to therapeutic design

The classical abscopal effect is defined here as objective regression of a verified non-irradiated tumor lesion following local radiotherapy. An immune abscopal phenomenon denotes a prespecified, reproducible immune change within such a lesion that is attributable to the local in...

Cyber behaviour and personality nexus: clustering around security attitudes, FoMO, problematic social media use, and cognitive and personality traits?

Abstract Our research examines whether cyber behaviours can be classified through personality factors. The study involved 642 participants, including 314 from the United Kingdom (UK) and 328 from the Arab Gulf Cooperation Council (GCC). Using conscientiousness, neuroticism and ne...

“Greeninflation”: evidence on the channels of transition

Purpose This paper aims to explore the role of two transmission channels between “green” transition and (overall and core) inflation, the so-called “greenflation” in the USA. The first channel is related to the “green” macroeconomic characteristics, and the second channel is asso...

A simulation study of underground hydrogen storage (UHS) in a partially depleted gas reservoir: A case study for the North Field, Qatar

The transition to a low-carbon energy future has shifted the global focus on hydrogen (H2) as a clean energy carrier, especially its role in blue ammonia production. H2 storage in aboveground tanks presents several challenges, including high material costs, limited capacity, safe...

The Proteinase Activated Receptor-2 mediates Protective Immunity in Early Experimental Leishmaniasis

Resistance to Leishmania (L.) major depends on the development of a L. major-specific Th1 response, while Th2 differentiation results in susceptibility. We previously showed that the early microenvironment of infected skin delivers important signals for T cell differentiation. We...

Comprehensive AI workflow for radiological report generation from radiographs

The manual generation of radiology reports is time-consuming and error-prone, particularly for less experienced radiologists, leading to inefficiencies and delays in clinical workflows as case volumes increase. Therefore, automated radiology report generation can serve as valuabl...

SLFN11 enhances cisplatin sensitivity in pediatric cancer via activation of stress-response and suppression of survival pathways

Abstract Background Paediatric cancers pose treatment challenges due to biological heterogeneity and variable chemotherapy responses. SLFN11, a DNA/RNA helicase-like protein known to sensitise adult tumours to DNA-damaging agents, remains underexplored in paediatric malignancies....
