MARTA: a high-energy cosmic-ray detector concept for high-accuracy muon measurement

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
A new concept for the direct measurement of muons in air showers is presented. The concept is based on resistive plate chambers (RPCs), which can directly measure muons with very good space and time resolution. The muon detector is shielded by placing it

A Natural Language Processing Approach to Identifying Partisan Framing of Climate Change Denialism, Fatalism, and Solutions in US Congressional Speeches

open access: yesPolicy Studies Journal, Volume 54, Issue 2, May 2026.
ABSTRACT This study examines the evolution of climate change discourse in the United States Congress from 1987 to 2017, employing natural language processing (NLP) techniques to analyze floor speeches. Using a la carte (ALC) word embeddings, we investigate how Democratic and Republican members of Congress frame climate change, focusing on denialist ...

Adipose‐Derived Extracellular Vesicles and Intercellular Crosstalk With Skeletal Muscle: Implications for Sarcopenic Obesity and Metabolic Dysregulation

open access: yesObesity Reviews, Volume 27, Issue 1, Page 1-22, January 2026.
ABSTRACT Sarcopenic obesity, characterized by the concurrent presence of excess adiposity and diminished skeletal muscle mass and function, is closely linked to frailty, chronic inflammation, and insulin resistance. The increasing prevalence of sarcopenic obesity is driven by the global aging population, widespread adoption of sedentary lifestyles, and

Take Me Home, Country Roads: Historical Diasporas and Contemporary FDI Patterns

open access: yesThe World Economy, Volume 49, Issue 1, Page 94-117, January 2026.
ABSTRACT We examine whether historical diasporas shape current foreign direct investment (FDI) flows, using Italian data from the ‘age of mass migration’ (1876–1925). We find that Italian regions with larger diasporas at the turn of the twentieth century maintain persistent economic ties with their historical destinations.
