Robust Hydraulic Fracture Monitoring (HFM) of Multiple Time Overlapping Events Using a Generalized Discrete Radon Transform

open access: yes, 2013
In this work we propose a novel algorithm for multiple-event localization for Hydraulic Fracture Monitoring (HFM) through the exploitation of the sparsity of the observed seismic signal when represented in a basis consisting of space time propagators. We

Scientific report on the determination of the presence of cannabinoids in industrial hemp food on the market of the Republic of Croatia

open access: yesFood Risk Assess Europe, Volume 3, Issue 4, October 2025.
Summary Cannabis sativa L. is one of the oldest cultivated plants on the planet. It was initially used by humans as a source of roughage for animals and as a textile fiber; over time, it has been used as a source of food and medicine. The plant contains bioactive compounds called cannabinoids. The best‐known cannabinoids occurring in Cannabis sativa L.

Land‐use changes impact root–fungal network connectivity in a global biodiversity hotspot

open access: yesJournal of Ecology, Volume 113, Issue 5, Page 1136-1149, May 2025.
Dimensioning the impacts of rainforest transformations below‐ground is constrained by our understanding of fungal functional guilds. Highly modified systems exhibited fewer connections, suggesting a dynamic restructuring of root–fungal relationships in response to land‐use changes.

A meta‐analysis of the association between teacher support and school engagement

open access: yesSocial Development, Volume 33, Issue 4, November 2024.
Abstract School engagement is a multidimensional concept describing how students behave, feel, and think. Previous meta‐analyses suggest that school engagement may be underpinned by specific aspects of teacher support. However, given that school engagement is also multifaceted, it is important to examine how each aspect of school engagement is related ...
