Bioactive PdPt nanosheets for hypoxia modulation-enhanced radiotherapy

With the global rise in cancer incidence, the development of effective and safe therapeutic strategies remains an urgent priority. Although radiotherapy (RT) is widely used in clinical oncology, its therapeutic efficacy is often compromised by the hypoxic tumor microenvironment,...

Co-optimization of storage service scheduling and bidding strategies for community-shared energy storage: a distributionally robust bi-level model

The co-optimization of market participation and user-side service provision is key to ensuring the effective operation of community-shared energy storage systems. In fulfilling this dual role, while user-side storage consumes finite resources, it introduces critical flexibility f...

Integrating a Ripple Filter into Pencil Beam Scanning Proton Therapy for Breast Cancer: from Dosimetric Feasibility to Acute Toxicity Assessment

Pencil beam scanning (PBS) proton therapy (PT) offers superior dosimetric advantages for breast cancer treatment. However, synchrotron-based facilities frequently encounter throughput limitations due to slow energy layer switching, particularly problematic for superficial targets...

The Pragmatics of Emotion in Artificial Intelligence: Theoretical and Applied Perspectives

This Special Issue of Corpus Pragmatics explores how emotion shapes and is shaped by language in interaction with artificial intelligence.As human communication increasingly involves intelligent systems, emotion emerges as both a linguistic signal and a computational construct.Ba...

Rotordynamic Performance Measurements and Model Predictions of Water-Lubricated Journal Bearings with Different Radial Clearances

This study develops a test rig to investigate the rotordynamic performance of a rotor system supported by water-lubricated journal bearings. The test evaluates the vibration response under the different radial clearances of bearing and validates the analytical data through experi...

Rethinking fossil fuel divestment: Land, labor, and crises of overaccumulation

Research on fossil fuel divestment has thus far focused on the efficacy of shifting finance away from fossil fuels to decarbonize investment portfolios. Drawing on a comparative analysis of fossil fuel divestment movements across the Asia Pacific, this article instead situates di...

Performance of selected North African barley genotypes based on agro-morphological and physiological traits under field conditions in Morocco

As climate change accelerates, the impact on barley production, particularly in water-limited regions, is becoming more pronounced. This study assesses the physiological and agronomic responses of nine barley genotypes from Morocco, Egypt, and Tunisia under rainfed conditions acr...

Neighboring Fe-Cr electronic coupling simultaneously promotes intrinsic activity and suppresses Fe-induced degradation for oxygen reduction electrocatalysis

Fe-N-C catalysts are among the most promising platinum-group-metal-free electrocatalysts for the oxygen reduction reaction (ORR), yet their practical application is limited by the insufficient intrinsic activity of isolated Fe sites and Fe-induced degradation. Herein, a neighbori...

Multi-dimensional market framework for electricity, environment, and security in Thailand’s energy transition

Achieving carbon neutrality in the power sector requires market designs that align economic efficiency with environmental sustainability and system reliability. This paper proposes a multi-dimensional electricity market-clearing framework that co-optimises carbon pricing, renewab...
