Jeg er nŸdt til at få overbevist venner, familie og kolleger om at komme med over på Signal el. lign.! I min Messenger-app kom der lige info om at Meta har ændret deres betingelser for behandling af personoplysninger, men at man kan gŸre indsigelse mod det.
Men uanset hvor jeg klikker mig hen, kommer der intet link frem til den indsigelsesformular de henviser til! De gŸr alt hvad de kan for at gŸre det umuligt. Grrrr!!! 🤬

Optical spectroscopic signatures of the red giant evolutionary state
Modern spectroscopic surveys output large data volumes. Theoretical models provide a means to transform the information encoded in these data to measurements of physical stellar properties. However, in detail the models are incomplete and simplified, and prohibit interpretation of the fine details in spectra. Instead, the available data provide an opportunity to use data-driven, differential analysis techniques, as a means towards understanding spectral signatures. We deploy such an analysis to…

Towards Fusion of Neural Audio Codec-based Representations with Spectral for Heart Murmur Classification via Bandit-based Cross-Attention Mechanism
In this study, we focus on heart murmur classification (HMC) and hypothesize that combining neural audio codec representations (NACRs) such as EnCodec with spectral features (SFs), such as MFCC, will yield superior performance. We believe such fusion will trigger their complementary behavior as NACRs excel at capturing fine-grained acoustic patterns such as rhythm changes, spectral features focus on frequency-domain properties such as harmonic structure, spectral energy distribution crucial for…

The origin of the coherent radio flash potentially associated with GRB 201006A
Rowlinson et al. 2023 recently claimed the detection of a coherent radio flash 76.6 minutes after a short gamma-ray burst. They proposed that the radio emission may be associated with a long-lived neutron star engine. We show through theoretical and observational arguments that the coherent radio emission, if real and indeed associated with GRB 201006A and at the estimated redshift, is unlikely to be due to the collapse of the neutron star, ruling out a blitzar-like mechanism. Instead, we show …

@merlelaperle.bsky.social@bsky.brid.gy hallo Merle, ich habe dir jetzt seit einigen Tagen hier im fediverse zugehört. War skeptisch ob deinem engagierten Fürsprechen für Threema - und kann dir trotzdem inhaltlich oft folgen, aber … die Empfehlung jemand möge an einem Galgen hängen, finde ich, für die Wahl seines persönlichen Messengrs zu überspitzt. Mögen seine oder deine Argumente stimmen, wird damit egal. Schade.

Ein reguliertes Flächenintegral als Entscheidungskriterium für die Riemannsche Vermutung
We present a novel integral criterion for the Riemann Hypothesis based on a regulated, normalized surface integral involving a logarithmic weight and the reciprocal square of the Riemann zeta function. The construction distinguishes symmetric from asymmetric zero configurations and converges if and only if all nontrivial zeros lie on the critical line. Analytical arguments are supported by model computations and operator-theoretic reformulations. The resulting structure provides a new functiona…
