Amanita theophili sp. nov. (Amanitaceae) from central Mexico

open access: yesNordic Journal of Botany, EarlyView.
Amanita theophili sp. nov., a member of Amanita sect. Amidella (Amanitaceae), is described from temperate pine‐oak forests in Morelos, central Mexico. Morphological features and phylogenetic analyses based on ITS and 28S rDNA sequences confirm its distinct taxonomic status. The new species is morphologically similar to A. peckiana and A.

Engaging the public in plant science: Communication facilitators and barriers of scaling up a citizen science campaign

open access: yesPeople and Nature, EarlyView.
Abstract Volunteers have been involved in nature observations for decades through citizen science initiatives, providing large data sets as well as problem identification that allow a more complete understanding of many natural phenomena. Although communication is a core component in citizen science, the key factors that determine its effectiveness in ...

Structural characterization and optimum machining parameters of jute/carbon fibre hybrid reinforced epoxy composite laminates

open access: yesPolymer International, EarlyView.
Hybrid jute/carbon epoxy laminates have better mechanical performance and less drilling damage by the use of optimized stacking sequence and machining parameters. Abstract Three composite laminate systems were produced using the standard hand lay‐up method: jute‐fibre‐reinforced polymer (JFRP), carbon‐fibre‐reinforced polymer (CFRP) and a hybrid of the

A Self‐Supervised Machine Learning Approach for the Estimation of Open‐Circuit Voltage Degradation in Photovoltaic Systems

open access: yesProgress in Photovoltaics: Research and Applications, EarlyView.
This study introduces a self‐supervised machine learning approach integrating physics‐based principles to estimate open‐circuit voltage (voc$$ {v}_{oc} $$) degradation in photovoltaic systems using SCADA data. By combining clustering and regression algorithms, our method detects performance deviations without labelled datasets.
