Equivariant Geometric Scattering Networks via Vector Diffusion Wavelets
We introduce a novel version of the geometric scattering transform for geometric graphs containing scalar and vector node features. This new scattering transform has desirable symmetries with respect to rigid-body roto-translations (i.e., $SE(3)$-equivariance) and may be incorporated into a geometric GNN framework. We empirically show that our equivariant scattering-based GNN achieves comparable performance to other equivariant message-passing-based GNNs at a fraction of the parameter count.

Transforming tubular packings to bicontinuous surfaces
The link between bicontinuous architectures in biological membranes and triply-periodic minimal surfaces (TPMS) is a well established example of stunning geometric form in nature. The prolamellar body (PLB) in early plant plastid development is a classic example, forming the Diamond TPMS in a lipid-protein-pigment membrane. However, the early development of such spectacular geometric structures is poorly understood. Inspired by the presence of tubules in the micrographs of early plastid membran…

Wonderful news: both The vOICe for Android and The vOICe web app (PWA) work fine on the new Samsung Galaxy XR (Android XR) headset! Many thanks to Michael Gschwandtner (@…) for preliminary test results shared via Twitter/X (@xrworkoutlabs). #noninvasive

Comet C/2025 A6 (Lemmon) is doing very well already, months before its perihelion - and it's not a transient outburst: "To measure the total brightness, the entire coma of 7' was used in Astrometrica," writes Michael Jäger in #comet *could* thus reach 2nd or 1st magnitude in late October / early November when it's observable in Ser, Her and Oph at a solar elongation of around 35° ... unless it decides to stay dimmer, of course.

Reproducible Physiological Features in Affective Computing: A Preliminary Analysis on Arousal Modeling
In Affective Computing, a key challenge lies in reliably linking subjective emotional experiences with objective physiological markers. This preliminary study addresses the issue of reproducibility by identifying physiological features from cardiovascular and electrodermal signals that are associated with continuous self-reports of arousal levels. Using the Continuously Annotated Signal of Emotion dataset, we analyzed 164 features extracted from cardiac and electrodermal signals of 30 participa…

«Verschiedene bürgerliche Parlamentarier haben mir gesagt, dass sie die Vorlage nicht gut fanden. Sie engagierten sich aber nicht dagegen, weil sie sich nicht gegen den Hauseigentümerverband stellen wollten. Hier sieht man die riesige Macht des HEV, der mit seinen finanziellen Zuwendungen und Wahlempfehlungen an Parteien und Kandidierende vor den Wahlen Einfluss darauf nimmt, wer ins Parlament kommt.»

IsoDAR@Yemilab: Preliminary Design Report -- Volume II: Medium Energy Beam Transport, Neutrino Source, and Shielding
This Preliminary Design Report (PDR) describes the IsoDAR electron-antineutrino source in two volumes which are mostly site-independent and describe the cyclotron driver providing a 60 MeV, 10 mA proton beam (Volume I); and the medium energy beam transport line (MEBT) and target (this Volume). The IsoDAR driver and target will produce about $1.15\cdot10^{23}$ electron-antineutrinos over five calendar years. Paired with a kton-scale liquid scintillator detector, this will enable a broad particle…

Boosting Payment Channel Network Liquidity with Topology Optimization and Transaction Selection
Payment channel networks (PCNs) are a promising technology that alleviates blockchain scalability by shifting the transaction load from the blockchain to the PCN. Nevertheless, the network topology has to be carefully designed to maximise the transaction throughput in PCNs. Additionally, users in PCNs also have to make optimal decisions on which transactions to forward and which to reject to prolong the lifetime of their channels. In this work, we consider an input sequence of transactions over…

Discovery and dynamics of a Sedna-like object with a perihelion of 66 au
Trans-Neptunian objects (TNOs) with large perihelion distances ($q > 60$ au) and semi-major axes ($a > 200$ au) provide insights into the early evolution of the solar system and the existence of a hypothetical distant planet. These objects are still rare and their detection is challenging, yet they play a crucial role in constraining models of solar system formation. Here we report the discovery of a Sedna-like TNO, 2023\,KQ$_{14}$, nicknamed `Ammonite', with $q = 66$ au, $a = 252$ au, and incl…
