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, Volume 34, Issue 7, Page 920-941, July 2026.
This study introduces a self‐supervised machine learning approach integrating physics‐based principles to estimate open‐circuit voltage ( voc) degradation in photovoltaic systems using SCADA data. By combining clustering and regression algorithms, our method detects performance deviations without labelled datasets. Results across three PV installations

From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

Observational data on Galactic supernova remnants: II. The supernova remnants within l = 90°-270° [PDF]

open access: yesSerbian Astronomical Journal, 2004
We have collected all the available data on Galactic supernova remnants given in the literature. The data of Galactic supernova remnants located in the Galactic longitude interval l=90° - 270° in all spectral bands are represented in this work.

Alkaline‐Earth Metal Complexes Based on Tridentate β‐Diketiminate Ligands Bearing a Tethered Secondary Amine: Synthesis and Characterization

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
Deprotonotion of a β‐diketiminate ligand with a tethered secondary amine resulted in highly stable heteroleptic complexes, but the formation of the dianionic ligand could not be achieved. The alkaline‐earth (Ae) metal chemistry of a β‐diketiminate (BDI) ligand with a bulky Ar‐substituent and a pendant amine arm was investigated. The ligand precursor HC[

The Self-Calibrating Hubble Diagram

open access: yes
As an increasing number of well measured type Ia supernovae (SNe Ia) become available, the statistical uncertainty on w has been reduced to the same size as the systematic uncertainty.

Whole Genome Assembly and Annotation of Two Invasive Sitona Species

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Weevils are a highly diversified taxon, comprising about 70,000 described species, including many of high economic importance. Here, we present whole genome assemblies and annotations of two Sitona species (Coleoptera: Curculionidae: Entiminae).

Examining Neutrino–Matter Interactions in the Cassiopeia A Supernova

open access: yesThe Astrophysical Journal, 2023
Neutrino interactions with stellar material are widely believed to be fundamental to the explosion of massive stars. However, this important process has remained difficult to confirm observationally.

Untangling supernova-neutrino oscillations with beta-beam data [PDF]

open access: yes
Recently, we suggested that low-energy beta-beam neutrinos can be very useful for the study of supernova neutrino interactions. In this paper, we examine the use of a such experiment for the analysis of a supernova neutrino signal.
