On the Effect of Tap Changers and Nonlinear Loads on Voltage Stability
On 21 June 2024, a severe incident happened in the South-Eastern part of the Continental European power system. After a voltage collapse, large parts of Albania, Montenegro, Bosnia and Herzegovina as well as Croatia suffered from a blackout [1]. The initial tripping of two transmission lines resulted in a voltage collapse in these countries. Investigations have shown that a) transformers with on-load tap changers (OLTC) and b) nonlinear loads, in particular air conditioning systems, played a si…

Minder immigratie in 2024, vooral minder kennismigranten
In 2024 kwamen 316 duizend immigranten naar Nederland. Dat waren er 19 duizend minder dan het jaar ervoor. Zowel de immigratie uit EU-landen als uit overige landen was lager dan in 2023, het aantal immigranten met de Nederlandse nationaliteit bleef gelijk. Vooral het aantal kennismigranten dat van buiten de EU naar Nederland kwam daalde. Dat meldt het CBS op basis van recente cijfers.

Comment on "Quantum tunneling from Schwarzschild black hole in non-commutative gauge theory of gravity"
The particle creation via quantum tunneling was recently calculated for the Schwarzschild non-commutative black hole solution in Ref. [Phys. Lett. B 848 (2024) 138335, e-Print: 2310.02445 [gr-qc]]. Nevertheless, it contains inconsistencies in the calculations that need to be properly corrected. In particular, the event horizon was incorrectly determined in that work, which affected all the subsequent calculations. Moreover, the same issue have been repeated elsewhere by the same authors in Refs…

Tiling with Three Polygons is Undecidable
We prove that the following problem is co-RE-complete and thus undecidable: given three simple polygons, is there a tiling of the plane where every tile is an isometry of one of the three polygons (either allowing or forbidding reflections)? This result improves on the best previous construction which requires five polygons.

Münster – China entwickelt sich immer schneller zum Motor für den globalen Ausbau der erneuerbaren Energien. Allein in den ersten sechs Monaten des Jahres 2025 wurden in China neue Solaranlagen mit einer Leistung von 210 GW (210.000 MW) neu errichtet. Das ist deutlich mehr als die gesamte installierte Solarleistung in den USA mit rund 178 GW (IRENA, 2024); Deutschland liegt Ende letzten Jahres bei 100 GW (MaStR, BNetzA).

Time-Dependent Hamiltonian Simulation via Time-Independent Dynamics in a Larger Space
In this paper, we present a proof-of-concept quantum algorithm for simulating time-dependent Hamiltonian evolution by reducing the problem to simulating a time-independent Hamiltonian in a larger space using a discrete clock Hamiltonian construction. A similar construction was first explored for this simulation problem by Watkins, Wiebe, Roggero, and Lee [PRX Quantum, 2024]. Our algorithm improves upon their work in terms of the dependence on evolution time and precision. In addition, the compl…

28 Years of Sun-as-a-star Extreme Ultraviolet Light Curves from SOHO EIT
The Solar and Heliospheric Observatory (SOHO) Extreme-ultraviolet Imaging Telescope (EIT) has been taking images of the Solar disk and corona in four narrow EUV bandpasses (171Å, 195Å, 284Å, and 304Å) at a minimum cadence of once per day since early 1996. The time series of fully-calibrated EIT images now spans approximately 28 years, from early 1996 to early 2024, covering solar cycles 23, 24, and the beginning of cycle 25. We convert this extensive EIT image archive into a time series of …

Phase transition properties via partition function zeros: The Blume-Capel ferromagnet revisited
Since the landmark work of Lee and Yang, locating the zeros of the partition function in the complex magnetic-field plane has become a powerful method for studying phase transitions. Fisher later extended this approach to complex temperatures, and subsequent generalizations introduced other control parameters, such as the crystal field. In previous works [Moueddene et al, J. Stat. Mech. (2024) 023206; Phys. Rev. E 110, 064144 (2024)] we applied this framework to the two- and three-dimensional B…

Scaling solutions for current-carrying cosmic string networks. II. Biased solutions
The charge-velocity-dependent one-scale model is an extension of the canonical velocity-dependent one-scale model which explicitly incorporates additional degrees of freedom on the string worldsheet, such as arbitrary currents and charges, expected in physically realistic models. A previous paper [Pimenta and Martins, Phys. Rev.

Among these, the $\sim$140 ks observation from 2014 was analyzed in detail for this study. This data provides the best statistics and was taken…

Predicting Qualification Thresholds in UEFA's incomplete round-robin tournaments via a Dixon and Coles Model
In the 2024/25 season, UEFA introduced the incomplete round-robin format in the Champions League and Europa League, replacing the traditional group stage with a single league phase table of all 36 teams. Now, the top eight qualify directly for the round of 16, while teams ranked 9th-24th enter a play-off round. Existing simulation-based analyses, such as those by Opta, provide guidance on points presumably needed for qualification but show discrepancies when compared to actual outcomes in the f…

Control of pedestal-top electron density using RMP and gas puff at KSTAR
We report the experimental results of controlling the pedestal-top electron density by applying resonant magnetic perturbation with the in-vessel control coils and the main gas puff in the 2024-2025 KSTAR experimental campaign. The density is reconstructed using a parametrized psi_N grid and the five channels of the line-averaged density measured by a two-colored interferometer. The reconstruction procedure is accelerated by deploying a multi-layer perceptron to run in about 120 microseconds an…

On recurrence coefficients of classical orthogonal polynomials
In Lett. Math. Phys. 114, 54 (2024) and 115, 70 (2025), the author introduces what is presented as a novel method for determining whether a sequence of orthogonal polynomials is "classical", based solely on its initial recurrence coefficients. This note demonstrates that all the results contained in those works are already encompassed by two general theorems previously established in J. Math. Anal. Appl. 515 (2022), Article 126390. A symbolic algorithm, implemented in Mathematica, is also provi…

A comprehensive Darcy-type law for viscoplastic fluids: I. Framework
A comprehensive Darcy-type law for viscoplastic fluids is proposed. Different regimes of yield-stress fluid flow in porous media can be categorised based on the Bingham number (i.e. the ratio of the yield stress to the characteristic viscous stress). In a recent study (Chaparian, J. Fluid Mech., vol. 980, A14, 2024), we addressed the yield/plastic limit (infinitely large Bingham number), namely, the onset of percolation when the applied pressure gradient is just sufficient to overcome the yield…

On Minimal Excludant over Overpartitions
A partition of a positive integer $n$ is a non-increasing sequence of positive integers which sum to $n$. A recently studied aspect of partitions is the minimal excludant of a partition, which is defined to be the smallest positive integer that is not a part of the partition. In 2024, Aricheta and Donato studied the minimal excludant of the non-overlined parts of an overpartition, where an overpartition of $n$ is a partition of $n$ in which the first occurrence of a number may be overlined.
