That day in our vacations we had a really beautiful walk around this lake.
Somehow I didn't really see any motifs. So I also didn't take a lot of photes - just this pan around the lake. But maybe that's also enough for such a warm day ;)

Synergistic motifs in linear Gaussian systems
Higher-order interdependencies are central features of complex systems, yet a mechanistic explanation for their emergence remains elusive. For linear Gaussian systems of arbitrary dimension, we derive an expression for synergy-dominance in terms of signed network motifs in the system's correlation matrix. We prove that antibalanced correlational structures ensure synergy-dominance and further show that antibalanced triads in the dyadic interaction matrix of Ornstein-Uhlenbeck processes are nece…

MDPG: Multi-domain Diffusion Prior Guidance for MRI Reconstruction
Magnetic Resonance Imaging (MRI) reconstruction is essential in medical diagnostics. As the latest generative models, diffusion models (DMs) have struggled to produce high-fidelity images due to their stochastic nature in image domains. Latent diffusion models (LDMs) yield both compact and detailed prior knowledge in latent domains, which could effectively guide the model towards more effective learning of the original data distribution. Inspired by this, we propose Multi-domain Diffusion Prior…

Hilarious and nevertheless a bit unpleasant new video of The Slow Mo Guys, but at least something completely different than their common weapons, explosions or balloons motives:

Weil ich neulich mitbekommen habe, dass das jemand nicht wusste: Habt Ihr Eure Posts alle auf „öffentlich“/„public“ gestellt oder evtl. versehentlich auf „ungelistet“ (oder das englische Äquivalent, das ich gerade nicht auswendig weiß / Edit: „quiet public“, danke @… )? Ich sehe hier manchmal Accounts, die sehr konsequent ungelistet tröten, und frage mich, ob das A…

Exact treatment of rotation-induced modifications in two-dimensional quantum rings
We investigate the influence of rotation on the Fermi energy, magnetization, and persistent current in two-dimensional quantum rings. Using the Tan-Inkson confinement potential and incorporating rotational effects through a non-inertial coupling, we derive analytical expressions for the energy levels and examine the modifications induced by rotation. We then numerically explore how variations in angular velocity affect the Fermi energy, magnetization, and persistent current. Our results show th…

Heute mitbekommen, was „Personen auf den Gleisen“ wirklich bedeutet.
Unser Probenraum liegt im 1. Stock, gleich neben den U-Bahn-Gleisen, die erhöht sind. Alle 5 Minuten fährt eine Bahn vorbei.
Während wir so proben, spaziert ein Jugendlicher auf den Gleisen vorbei, hat keinen sicheren Gang. Alle sind verduzt. Einer von uns handelt schnell. Er ruft: „Hey, geh runter da!“ Der Jugendliche reagiert nicht. 1/2
