Identifying Radio Active Galactic Nuclei with Machine Learning and Large-Area Surveys
Context. Active galactic nuclei (AGNs) and star forming galaxies (SFGs) are the primary sources of extragalactic radio sky. But it is difficult to distinguish the radio emission produced by AGNs from that by SFGs, especially when the radio sources are faint. Best et al. (2023) classified the radio sources in LoTSS Deep Fields DR1 through multiwavelength SED fitting. With the classification results of them, we perform a supervised machine learning to distinguish radio AGNs and radio SFGs. Aims…

Measurement of coherent exclusive $J/ψ\toμ^+μ^-$ production in ultraperipheral Pb+Pb collisions at $\sqrt{s_{\textrm{NN}}}=5.36$ TeV with the ATLAS detector
The ATLAS experiment has performed a measurement of coherent exclusive $J/ψ\toμ^+μ^-$ production in ultraperipheral Pb+Pb collisions at $\sqrt{s_{\textrm{NN}}}=5.36$ TeV. The data was recorded at the Large Hadron Collider (LHC) during 2023, and corresponds to an integrated luminosity of 78 $μ$b$^{-1}$. Exclusive $J/ψ$ candidates were selected with a dedicated track-sensitive trigger based on the ATLAS transition radiation tracker. The analysis involves reconstruction of the dimuon invarian…

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.

On quantum ergodicity for higher dimensional cat maps modulo prime powers
A discrete model of quantum ergodicity of linear maps generated by symplectic matrices $A \in \mathrm{Sp}(2d,\mathbb{Z})$ modulo an integer $N\ge 1$, has been studied for $d=1$ and almost all $N$ by P. Kurlberg and Z. Rudnick (2001). Their result has been strengthened by J. Bourgain (2005) and subsequently by A. Ostafe, I. E. Shparlinski, and J. F. Voloch (2023). For arbitrary $d$ this has been studied by P. Kurlberg, A. Ostafe, Z. Rudnick and I. E. Shparlinski (2024). The corresponding equidis…

Overall, 77% of Americans said they did not feel “completely financially secure,”
and 32% said they did not think they ever would.
Based on the latest census data, the median U.S. household income in 2023 was roughly $80,000,
but that is the midpoint on incomes, meaning half of U.S. households made even less.

This is how much Americans need to make in order to ‘feel comfortable,’ according to a survey

Establishment of global phase coherence in a highly disordered fractal MgO/MgB2 nanocomposite: Roles of interface, morphology and defect
Recently, we have reported that a highly disordered fractal MgO/MgB2 nanocomposite exhibits bulk-like superconducting properties with isotropic pinning, showing an excellent phase-coherent capability irrespective of the low volume fraction (~30 vol. %) of MgB2 [Uchino et al., Phys. Rev. B 101, 035146 (2020); Teramachi et al,, Phys. Rev. B 108, 155146 (2023)]. Hence, this nanocomposite provides a useful experimental system to investigate the relationship between the structural disorder and the e…

The hard-core probabilistic cellular automaton has attracted a renewed interest in the last few years, thanks to its connection with the study of a combinatorial game on percolation configurations. We provide an alternative proof for the ergodicity of this PCA for a neighbourhood of size $2$ and $3$, using the notion of decorrelated islands introduced by Casse in 2023, together with some new ideas. This shortens the previous proofs and provides a more intuitive and unified approach.

Charged-particle production in pp collisions at 13.6 TeV and Pb-Pb collisions at 5.36 TeV with ALICE
The first measurements of the charged-particle pseudorapidity density, ${\rm d}N_{\rm{ch}}/{\rm d}η$, in proton-proton (pp) collisions at $\sqrt{s} =$ 13.6 TeV and in lead-lead (Pb-Pb) collisions at $\sqrt{s_{\rm{NN}}} = $ 5.36 TeV are presented. The analysis is based on Run 3 data recorded in 2022 and 2023, using the upgraded ALICE detector at the LHC. The average charged-particle pseudorapidity density $\langle{\rm d}N_{\rm{ch}}/{\rm d}η\rangle$ in pp collisions was measured at midrapidity …

AI-Based Software Vulnerability Detection: A Systematic Literature Review
Software vulnerabilities in source code pose serious cybersecurity risks, prompting a shift from traditional detection methods (e.g., static analysis, rule-based matching) to AI-driven approaches. This study presents a systematic review of software vulnerability detection (SVD) research from 2018 to 2023, offering a comprehensive taxonomy of techniques, feature representations, and embedding methods. Our analysis reveals that 91% of studies use AI-based methods, with graph-based models being th…

Layered tree-independence number and clique-based separators
Motivated by a question of Galby, Munaro, and Yang (SoCG 2023) asking whether every graph class of bounded layered tree-independence number admits clique-based separators of sublinear weight, we investigate relations between layered tree-independence number, weight of clique-based separators, clique cover degeneracy and independence degeneracy. In particular, we provide a number of results bounding these parameters on geometric intersection graphs. For example, we show that the layered tree-ind…

Scale-by-scale energy transfers in bubbly flows
Variable density buoyancy-driven bubbly flows allow for multiple definitions of scale-dependent (or filtered) energy. A priori, it is not obvious which of these provide the most physically apt scale-by-scale budget. In the present study, we compare two such definitions, based on (a) filtered momentum and filtered velocity (Pandey et al., 2020), and (b) Favre filtered energy (Aluie 2013, Pandey et al., 2023). We also derive a Kármán-Howarth-Monin (KHM) relation using the momentum-velocity corr…

We propose a formalisation of recursive semantic anchoring, attaching to every language entity $χ$ a family of fixed-point operators $ϕ_{n,m}$ that model bounded semantic drift via the relation $ϕ_{n,m}(χ) = χ\oplus Δ(χ)$, where $Δ(χ)$ is a drift vector in a latent semantic manifold.

JUICE was launched in April 2023, and it is now in its cruise phase to Jupiter, where it is scheduled to arrive in July 2031. JUICE carries a radiation monitor, namely the RADiation hard Electron Monitor (RADEM) to measure protons, electrons, and ions, detecting particles coming mainly from the anti-Sun direction. On 2024 May 13, a large solar energetic particle (SEP) event took place in association with an eruption close to the western limb of the Sun as seen from Earth. Providentially, at tha…

The Observations of Magnetic Reconnection During the Interaction Process of Two Active Region Filaments
We investigate the interaction between two filaments (F1 and F2) and their subsequent magnetic reconnection in active region (AR) NOAA 13296 and AR NOAA 13293 on May 9, 2023, utilizing high spatial and temporal resolution and multi-wavelength observational data from the Solar Dynamics Observatory, the New Vacuum Solar Telescope, and the Chinese Hα Solar Explorer. The movement of F1 from the southeast toward the northwest, driven by the motion of the positive magnetic polarity (P1), leads to a …

Dust production rates in Jupiter-family comets II: Trends and population insights from ATLAS photometry of 116 JFCs
Jupiter-family comets (JFCs) have orbital periods of less than 20 years and therefore undergo more frequent sublimation compared to other comet populations. The JFCs therefore represent the ideal dynamical population for investigating the dust production rates at high-cadence. We analyzed observations by the Asteroid Terrestrial-impact Last Alert System (ATLAS) of 74 JFCs that reached perihelion in 2022 and 2023. The work contained in this study builds upon our previous work (Gillan et al. 2024…

Anmerkung: Erste Versuche einer #Datenanalyse

Anzahl der installierten Windkraftanlagen pro Jahr in Deutschland mit Stand vom 09.08.2025. Die Grafik zeigt ein vertikales Balkendiagramm von 1949 bis 2025. Die Höhe jedes Balkens entspricht der Anzahl neuer Inbetriebnahmen pro Jahr (Wertbeschriftung auf jedem Balken). Bis Ende der 1980er Jahre liegen die jährlichen Zuwächse bei unter zehn Anlagen, ab 1990 steigt die Zahl kontinuierlich (z. B. 525 im Jahr 1996). Spitzenwerte erreichen 2159 (2023) und 2045 (2024).
