Allein auf dem Minigrundstück ums #klexenhaus brüten derzeit mindestens 6 Vogelpaare (es könnte außerdem eine hohe Dunkellziffer in den Sträuchern und Hecken geben) und ich finde das gar wundervoll.

SGPMIL: Sparse Gaussian Process Multiple Instance Learning
Multiple Instance Learning (MIL) offers a natural solution for settings where only coarse, bag-level labels are available, without having access to instance-level annotations. This is usually the case in digital pathology, which consists of gigapixel sized images. While deterministic attention-based MIL approaches achieve strong bag-level performance, they often overlook the uncertainty inherent in instance relevance. In this paper, we address the lack of uncertainty quantification in instance-…

And if you're wondering what happened to those three Fast Cats.
In January 2024 someone tried to get someone to buy them by putting them up on Facebook Marketplace (yep!) for $15 Million for all three. (98% off original price lol). They were, and likely still are, sitting tied up in Alexandria, Egypt. They were last owned by the Egyptian Government.
At least one of them was essentially unchanged inside since the 1990s. (a Nanaimo Bar for $1.5!)

Neutron-induced opalescence in silica glass
Light scattering intensity distribution along the optical fiber length is analyzed, which was measured by optical time domain reflectometry (OTDR) during and after fiber irradiation in a nuclear reactor. The OTDR traces prove to contain two components associated with either radiation-induced attenuation (RIA), or with Rayleigh scattering coefficient (RSC) variation. The RSC increase effect in the first stage of fast-neutron irradiation is argued to be similar to the anomalous scattering buildup…

Chemical abundances and small-scale gas kinematics in the local star-forming galaxy NGC 2366
We present a detailed spectroscopic study of ionised gas in the nearby (~3.3Mpc) dwarf galaxy NGC 2366, a local analogue of Green Pea galaxies, based on observations with the SCORPIO-2 instrument at the Russian 6-m BTA telescope. Using scanning Fabry-Perot interferometry and long-slit spectroscopy, we examine the gas kinematics, excitation mechanisms, and chemical abundances across the disc of NGC 2366, including its prominent starburst region Mrk 71 and the companion region NGC 2363. We identi…

Off-resonant light-induced topological phase transition and thermoelectric transport in semi-Dirac materials
We show that a semi-Dirac (SD) system with an inversion symmetry breaking mass exhibits a topological phase transition when irradiated with off-resonant light. Using Floquet theory, we derive the band structure, Chern numbers, phase diagram, and we show that as the light intensity is swept at fixed mass, the SD system undergoes normal-Chern-normal insulator transition. Along the phase boundaries we observe single semi-Dirac-cone (SSDC) semimetal states in which one SD cone is gapless and the ot…

Algebraic structures of Vassiliev invariants for knot families
We explore algebraic relations on Vassiliev knot invariants expressed through correlators in the 3-dimensional Chern-Simons theory. Vassiliev invariants form an infinite-dimensional algebra. We focus on $k$-parametric knot families with Vassiliev invariants being polynomials in family parameters. It turns out that such a 1-parametric algebra of Vassiliev invariants is always finitely generated, while in the case of more parameters, the number of generators can be infinite. Inside a knot family,…

Automated Charge Transition Detection in Quantum Dot Charge Stability Diagrams
Gate-defined semiconductor quantum dots require an appropriate number of electrons to function as qubits. The number of electrons is usually tuned by analyzing charge stability diagrams, in which charge transitions manifest as edges. Therefore, to fully automate qubit tuning, it is necessary to recognize these edges automatically and reliably. This paper investigates possible detection methods, describes their training with simulated data from the SimCATS framework, and performs a quantitative …
