Recent results on elastic scattering and single-neutron stripping reaction in the18O+48Ti collision at 275 MeV
(National Documentation Centre, 2024) Sgouros, O.; Brischetto, G.A.; Cappuzzello, F.; Cavallaro, M.; Carbone, D.; Agodi, C.; Hacısalihoğlu, Aylin; Close Zagatto V.A.B.
A global study of the18O+48Ti collision at 275 MeV was carried out within the NUMEN and NURE experimental campaigns by measuring the complete net of nuclear reactions which may be involved in the48Ti→48Ca double charge exchange transition. The relevant experiment was visualized at the INFN-LNS in Catania, where angular distribution measurements for a plethora of reaction channels were performed by means of the MAGNEX large acceptance magnetic spectrometer. The present work provides an overview of the analyses of the elastic scattering and one-neutron transfer reaction channels.
Periostin and fibronectin in nasal lesions: Key players in polyps and inverted papillomas

Background Sinonasal lesions are common benign masses with overlapping cli nical and histopathological features. Extracellular matrix proteins such as periostin, fibronectin, and tenascin-C play key roles in tissue remodeling and inflammation, yet their distinct expression profiles in these lesions remain poorly defined. Aim This study aimed to compare the immunohistochemical staining patterns of periostin, fibronectin, and tenascin-C in sinonasal lesions to elucidate their roles in pathogenesis and enhance differential diagnosis. Methods In this retrospective study, pathological specimens from 70 patients who underwent surgery for sinonasal polyps were analyzed. Immunohistochemical expression of periostin, fibronectin, and tenascin-C was assessed separately in epithelial and stromal compartments using a semi-quantitative scoring system. Associations between staining patterns and lesion types were evaluated using multinomial logistic regression. Results The cohort had a male-to-female ratio of 5:2 with a mean age of approximately 40 years. Nasal polyps demonstrated significantly higher stromal periostin staining compared to both antrochoanal polyps and inverted papillomas. Conversely, antrochoanal polyps exhibited significantly elevated epithelial periostin expression relative to inverted papillomas. Fibronectin expression was markedly increased in nasal polyps, especially in the stroma, supporting its role in inflammatory tissue remodeling. Tenascin-C expression did not differ significantly among the lesion types. Conclusions Differential expression of periostin and fibronectin suggests distinct pathogenic mechanisms in sinonasal lesions. The compartment-specific staining patterns of periostin, along with the prominent fibronectin expression in nasal polyps, suggest these biomarkers could serve as valuable diagnostic tools and potential therapeutic targets. Further research is needed to explore these pathways in sinonasal disease management.
From global challenges to specific solutions: climate change impacts on agriculture with a focus on sorghum through bibliometric analysis
(Springer Nature, 2025) Liaqat, Waqas; Altaf, Muhammad Tanveer; Jan, Muhammad Faheem; Ahmad, Haseeb; Khan, Ehtisham Hassan; Mohamed, Heba I.
Climate change significantly threatens global agriculture, with rising temperatures, erratic precipitation, and extreme weather events undermining crop productivity and food security. This study employs bibliometric analysis to explore the research landscape on sorghum, a climate-resilient crop, using 1,040 articles from the Web of Science Core Collection (1990–2023). Sorghum’s resilience to drought, heat, and salinity positions it as a viable alternative to traditional cereals in climate-stressed regions. The analysis highlights the USA, India, and Australia as leading contributors, with prominent institutions like the International Crops Research Institute for the Semi-Arid Tropics and Kansas State University driving innovations. The top journals, including Agricultural and Forest Meteorology and Sustainability, and prolific authors, such as Prasad PVV and Sultan B, underscore the field’s vibrant research ecosystem. Emerging themes, including drought tolerance, genetic improvement, and food security, reflect the crop’s growing importance in sustainable agriculture. This study provides a comprehensive overview of research trends and offers actionable insights for future studies and policy development. It also aids researchers in selecting publication outlets and fostering collaborations, emphasizing sorghum’s potential to mitigate climate change impacts and ensure food security.
Smart solutions for sustainable access and technological equity: the effect of energy transition, artificial intelligence, and digital economy on energy poverty
(John Wiley and Sons Ltd, 2025) Pilatin, Abdulmuttalip; Radulescu, Magdalena; Alofaysan, Hind; Barut, Abdulkadir; Huseynova, Rena
The integration of energy transition, artificial intelligence, and the digital economy represents a significant shift in the global effort to combat energy poverty and offers innovative tools and approaches to increase energy access, efficiency, and affordability for underserved populations. This study examines the impact of energy transition, artificial intelligence, and the digital economy on energy poverty in emerging market countries for the period 2005–2019 using a robust current estimator, the MMQREG estimator. The GMM estimator was used to assess the robustness of the results of the MMQREG estimator. The analysis found that artificial intelligence improves energy poverty, while the energy transition and the digital economy worsen it. Furthermore, the control variables, economic growth, financial development, and urbanisation, are found to improve energy poverty. In this context, policy recommendations are developed based on the obtained results and contribute to the discourse on technological equality by emphasising the importance of integrating artificial intelligence in developing countries.
Beyond the turbine: Charting the ecological footprint trajectory of wind energy technology budgets
(SAGE Publications Inc., 2025) Wu, Di; Huang, Anzhong; Ali, Sajid; Nazar, Raima; Anser, Muhammad Khalid
Amid the world's pursuit of environmental responsibility, strategic investments in wind energy technology reveal a powerful synergy, illuminating the path toward a greener and more sustainable future. This research explores the asymmetric association between wind energy technology budgets and ecological footprint in ten leading nations that invest the most in wind energy R&D (USA, China, Italy, UK, Brazil, France, India, Spain, Canada, and Germany). Prior investigations utilized panel data approaches to probe the wind energy technology-environment nexus without accounting for the specific qualities of various economies. Contrarily, the current research adopts the Quantile-on-Quantile methodology to appraise this relationship individually for every nation. This unique approach improves the exactness of our estimation, delivering a holistic global viewpoint while delivering customized perceptions for every particular economy. The annual data for the economies extends between 2000 and 2023. The findings indicate that dedicating resources to wind energy technology improves environmental quality by reducing the ecological footprint across several quantiles in selected counties. Furthermore, the findings highlight the diverse behaviors of these linkages in sample economies. These results underline the significance of policymakers performing exhaustive appraisals and executing efficient measures to allocate wind energy technology budgets for ecological sustainability. Highlights: The study analyzes wind energy technology-ecological footprint nexus. A unique methodology, “Quantile-on-Quantile (QQ),” is used. Wind energy technology reduces ecological footprint.
