An Account of Luck, Fortune, and Fate

open access: yesPhilosophy and Phenomenological Research, EarlyView.
ABSTRACT Luck is one of our most important concepts. In this article, I first argue that extant accounts of luck are deeply flawed. I then argue for a hybrid account of luck that is based around the difference between skill‐based and non‐skill‐based events.

Determining neutrino and supernova parameters with a galactic supernova [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2007
We investigate the sensitivity of some of the proposed next-generation neutrino experiments to a galactic supernova. In particular, we study how well the supernova parameters (the average energies and luminosities) can be separated from the unknown neutrino oscillation parameters ($θ_{13}$ and the neutrino mass hierarchy).

Supernovae and cosmology [PDF]

open access: yesGeneral Relativity and Gravitation, 2007
The extreme luminosity and their fairly unique temporal behaviour have made supernovae a superb tool to measure distances in the universe. As complex astrophysical events they provide interesting insights into explosion physics, explosive nucleosynthesis, hydrodynamics of the explosion and radiation transport.

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

Synthesis, Characterization, and Anti‐Plasmodium falciparum Activity of a New Copper(II) Complex Containing 2‐(Tert‐Butoxy)‐6‐(1H‐imidazol‐1‐yl)pyridine

open access: yesChemMedChem, Volume 21, Issue 11, 15 June 2026.
The graphical abstract illustrates the formation of a Cu(II) complex from azole‐based ligand, highlighting metal–ligand synergy. The resulting coordination compound acts as a bioactive entity against Plasmodium, where metal coordination enhances antiparasitic activity, outperforming the free ligand and demonstrating its potential as an antimalarial ...

Laser bathymetry on rough riverbed channels: State‐of‐the‐art and future prospects

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 6, June 2026.
This literature review found that topo‐bathymetric LiDAR has been successfully used to capture the structures of rough riverbeds and detect large boulders. While all of the studies that were reviewed used sensors that were operated from fixed‐wing aircraft, few studies have yet tested UAV‐borne sensors on rough riverbeds, despite the potential offered ...

PHYSICS OF SUPERNOVAE

open access: yesInternational Journal of Modern Physics A, 2005
The origin of cosmic rays (CR) is supposed to be closely connected with supernovae (SNe) which create the conditions favorable for various mechanisms of the CR acceleration to operate effectively. First, modern ideas about the physics of the SN explosion are briefly discussed: the explosive thermonuclear burning in degenerate white dwarfs resulting in

Synthesis, X‐Ray Analysis, Anticancer Activity, Computational, and in Silico Studies of New Thiophene Pyrazole Conjugates

open access: yesChemistryOpen, Volume 15, Issue 6, June 2026.
Two new thiophene–pyrazole derivatives, 8a and 8b, were synthesized from thiophene 3 precursor and fully characterized. The structure of 8a was confirmed by single‐crystal X‐ray diffraction, which revealed a nonplanar conformation stabilized by NH···O hydrogen bonding and weak intermolecular contacts.

La‐Tuned Scintillators With Nanosecond Response and High Flexibility for Blur‐Free X‐Ray Imaging

open access: yesSmartMat, Volume 7, Issue 3, June 2026.
This work presents a zero‐dimensional Ce (III)‐based hybrid halide scintillator designed for real‐time and flexible X‐ray imaging. La3+ alloying synergistically enhances photoluminescence efficiency while preserving nanosecond‐scale decay. The resulting material exhibits a high light yield and low detection limit.

Martian Proton Albedo as Signature of Near‐Surface Water

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract Understanding the Martian soil water budget is crucial not only for in situ resource utilization in future human missions to Mars, but also for reconstructing the geological and climatic history of the planet, as well as to assess the potential of ancient or even present microbial life.
