Experimental Demonstration of Radio‐Frequency Hong‐Ou‐Mandel Interference With Emulated Single‐Photon States

open access: yesAdvanced Physics Research, EarlyView.
We report an experimental demonstration of room‐temperature Hong–Ou–Mandel interference at a radio‐wave frequency of 120 MHz using emulated single‐photon states conditionally built from classical phase‐averaged coherent states. Our technique and results open the door to realizing quantum protocols in frequency ranges where standard quantum technologies

Design of experiments‐driven optimization of Porphyridium marinum cultivation: impact of operational variables on phycoerythrin and exopolysaccharide production

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Among the Porphyridium genus, Porphyridium marinum exhibits the highest phycoerythrin (PE) content. In this study, the metabolic trade‐off between biomass, PE, and sulfated exopolysaccharide (EPS) production was assessed under varying nitrogen and sulfur availability, light intensity, residence time, and cultivation mode.

For the Few, Not the Many: Tracing the Residualist and Compensatory Nature of British Energy Support

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT Drawing on extensive documentary analysis, this article traces the evolution of British energy policy support since World War II. It analyses shifts in policy design through two interpretive lenses: eligibility (residualist vs. universalist) and function (compensatory vs. preventive).

Different Conditions, Yet Similar Outcomes: How Interaction Between Policy Areas Enabled Carbon Tax Adoption in Sweden and Mexico

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT The interest in putting a price on carbon emissions is increasing in pace with the urgency of climate change. In this article we compare the adoption of one such policy instrument, carbon taxation, in the cases of Sweden and Mexico. We use a theoretical framework that focuses on economic and environmental factors influencing the policy process

Diagnostic Performance of Comprehensive Point‐of‐Care Ultrasound for Pediatric Tuberculosis in Spain: A Prospective Observational Study

open access: yesJournal of Clinical Ultrasound, EarlyView.
In children with presumptive tuberculosis, comprehensive point‐of‐care (cPOCUS) identified key thoracic abnormalities with high specificity and excellent inter‐reader reliability. Although diagnostic sensitivity was modest and examinations often incomplete, cPOCUS shows promise as a complementary, radiation‐free imaging tool.

Seed co‐occurrence caused by shared frugivores leaves a long‐lasting signal in the spatial co‐occurrence among plants

open access: yesOikos, EarlyView.
By dispersing seeds, frugivorous animals affect spatial co‐occurrence of plants, ultimately influencing plant community dynamics. Frugivorous animals are intrinsically involved in plant community dynamics, by dispersing seeds of fleshy‐fruited plants and influencing their spatial co‐occurrence.
