Amerikaanse energierekening stijgt harder dan inflatie, arme huishoudens in de problemen.
Oorzaak: groeiende elektriciteitsvraag vanuit datacenters en het hoge aandeel aardgas in de elektriciteitsproductie. Aardgas is ook in de VS in prijs gestegen door de gegroeide export naar de EU.
De meest logische stap om de prijs te verlagen: meer wind, zon en energieopslag. Alleen gaat dat tegen Trump's fossiele geloof in.

Russland will atomaren Schutzschild ausbauen
Russland will seinen atomaren Schutzschild ausbauen. Grund dafür seien die "kolossalen Bedrohungen" für die größte Atommacht der Welt, sagt der Chef der staatlichen Atombehörde Rosatom, Alexej Lichatschow, einer amtlichen Nachrichtenagentur zufolge.
"Der nukleare Schutzschild, der auch ein Schwert ist, ist eine Garantie für unsere Souveränität", sagt Lichatschow. "Wir verstehen he…

Ukraine-Liveblog: ++ Lawrow: Europäische Truppen in Ukraine "inakzeptabel" ++
Russlands Außenminister Lawrow hat einen möglichen Friedenseinsatz europäischer Truppen in der Ukraine als "völlig inakzeptabel" bezeichnet. Die Ukraine testete laut Präsident Selenskyj erfolgreich eine Rakete mit 3.000 Kilometern Reichweite.

A smoothed proximal trust-region algorithm for nonconvex optimization problems with $L^p$-regularization, $p\in (0,1)$
We investigate a trust-region algorithm to solve a nonconvex optimization problem with $L^p$-regularization for $p\in(0,1)$. The algorithm relies on descent properties of a so-called generalized Cauchy point that can be obtained efficiently by a line search along a suitable proximal path. To handle the nonconvexity and nonsmoothness of the $L^p$-pseudonorm, we replace it by a smooth approximation and construct a convex upper bound of that approximation. This enables us to use results of a trust…

The role of three-dimensional effects on ion injection and acceleration in perpendicular shocks
Understanding the conditions that enable particle acceleration at non-relativistic collisionless shocks is essential to unveil the origin of cosmic rays. We employ 2D and 3D hybrid simulations (with kinetic ions and fluid electrons) to explore particle acceleration and magnetic field amplification in non-relativistic perpendicular shocks, focusing on the role of shock drift acceleration and its dependence on the shock Mach number. We perform an analysis of the ion injection process and demonstr…

The nine model category structures on the category of sets
We give a proof of the folklore theorem, attributed to Goodwillie, that there are precisely nine model structures on the category $\mathsf{Set}$ of sets. This result is deduced from a complete study of lifting problems and the ensuing classification of all weak factorization systems on $\mathsf{Set}$. Moreover, we determine the Quillen equivalences between these model structures and exhibit an explicit example of equivalent model structures that cannot be realized by a single Quillen adjunction.

The Unexplored Dusty Nova LMCN 2009-05a in the Large Magellanic Cloud
We present a detailed spectrophotometric study of nova LMCN 2009-05a, located in the Large Magellanic Cloud (LMC). Photometric observations reveal a dust dip in the optical light curve, classifying it as a D-class nova. Light curve analysis yields t2 and t3 decline times of approximately 46 and 80 days, respectively, placing the nova in the category of moderately fast novae. Spectroscopic observations cover multiple phases, including pre-maximum, early decline, and nebular. The spectra are init…

Stemming -- The Evolution and Current State with a Focus on Bangla
Bangla, the seventh most widely spoken language worldwide with 300 million native speakers, faces digital under-representation due to limited resources and lack of annotated datasets. Stemming, a critical preprocessing step in language analysis, is essential for low-resource, highly-inflectional languages like Bangla, because it can reduce the complexity of algorithms and models by significantly reducing the number of words the algorithm needs to consider. This paper conducts a comprehensive su…
