What's there beyond the sun and the sea? Detecting tourists' interest towards nature in a mass tourism destination using social media data

open access: yesPeople and Nature, Volume 8, Issue 6, Page 1802-1816, June 2026.
Abstract Nature‐based tourism is a rapidly growing subsector of the international tourism industry. However, capturing broad‐scale patterns of nature visits during touristic trips or visitors' appreciation of nature may be difficult using traditional data sources and methods. In this study, we harness geotagged social media data to understand the scale

Data‐Driven Review and Machine Learning Prediction of Diamond Vacancy Center Synthesis

open access: yesAdvanced Intelligent Systems, Volume 8, Issue 5, May 2026.
A machine learning framework is applied to photoluminescence spectra to extract linewidths and uncover how NV, SiV, GeV, and SnV centers evolve with growth and processing conditions. Unified normalization and k‐fold validation reveal cross‐method trends and enable rapid prediction of defect size and fabrication parameters, offering a data‐driven route ...

fastbioclim: An R package for creating custom‐time bioclimatic and derived environmental summary variables

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 5, Page 1585-1594, May 2026.
Abstract Bioclimatic variables, widely used in ecological and biogeographical studies, are typically derived from 30‐year averages of monthly data (e.g. 1971–2000). Unfortunately, the use of these long‐term averaged variables often creates a temporal mismatch with the observational data collected, which potentially undermines how environmental ...

Performing Relevant Irradiation Experiments: The Role of Proton Flux in the Dynamic Annealing during Irradiation of Cu(In,Ga)Se2‐Based Solar Cells

open access: yesphysica status solidi (RRL) – Rapid Research Letters, Volume 20, Issue 2, February 2026.
Energetic particles make space a harsh environment that solar cells must endure. This study demonstrates that proton flux critically affects radiation damage in Cu(In,Ga)Se2 solar cells. By irradiating identical cells at different fluxes, a flux‐dependent balance between defect generation and dynamic annealing was revealed.
