Even before Microsoft Azure had a global failure this week,
Austria's Ministry of Economy had taken a decisive step toward digital sovereignty.
The Ministry is migrating 1,200 employees to a Nextcloud-based cloud and collaboration platform hosted on Austrian-based infrastructure
It's the latest move in a European trend to shift away from Big Tech.

European governments and agencies want to control sensitive data.

Another European agency shifts off Big Tech, as digital sovereignty movement gains steam
European Union states are increasingly shifting toward European-based companies that offer open-source solutions. Here's why.

Unlocking the Potential of Soft Actor-Critic for Imitation Learning
Learning-based methods have enabled robots to acquire bio-inspired movements with increasing levels of naturalness and adaptability. Among these, Imitation Learning (IL) has proven effective in transferring complex motion patterns from animals to robotic systems. However, current state-of-the-art frameworks predominantly rely on Proximal Policy Optimization (PPO), an on-policy algorithm that prioritizes stability over sample efficiency and policy generalization. This paper proposes a novel IL f…

TOI-1438: A rare system with two short-period sub-Neptunes and a tentative long-period Jupiter-like planet orbiting a K0V star
We present the detection and characterisation of the TOI-1438 multi-planet system discovered by TESS. We collected a series of follow-up observations including high-spectral resolution observations with HARPS-N over a period of five years. Our modelling shows that the K0V star hosts two transiting sub-Neptunes with Rb = 3.04 +/- 0.19 RE, Rc = 2.75 +/- 0.14 RE, Mb = 9.4 +/- 1.8 ME, and Mc = 10.6 +/- 2.1 ME. The orbital periods of planets b and c are 5.1 and 9.4 days, respectively, corresponding …

Physics-informed GNN for medium-high voltage AC power flow with edge-aware attention and line search correction operator
Physics-informed graph neural networks (PIGNNs) have emerged as fast AC power-flow solvers that can replace classic Newton--Raphson (NR) solvers, especially when thousands of scenarios must be evaluated. However, current PIGNNs still need accuracy improvements at parity speed; in particular, the physics loss is inoperative at inference, which can deter operational adoption. We address this with PIGNN-Attn-LS, combining an edge-aware attention mechanism that explicitly encodes line physics via p…

Bridging the Regulatory Divide: Ensuring Safety and Equity in Wearable Health Technologies
As wearable health technologies have grown more sophisticated, the distinction between "wellness" and "medical" devices has become increasingly blurred. While some features undergo formal U.S. Food and Drug Administration (FDA) review, many over-the-counter tools operate in a regulatory grey zone, leveraging health-related data and outputs without clinical validation. Further complicating the issue is the widespread repurposing of wellness devices for medical uses, which can introduce safety ri…

Return of the clocked burster GS~1826$-$238
We report the discovery of an exceptionally short burst recurrence time in the well-known clocked burster GS~1826$-$238, observed with the CubeSat X-ray observatory NinjaSat. The source had remained in a persistent soft spectral state since its hard-to-soft transition in 2015 July until a soft-to-hard transition occurred in 2025 May. On 2025 June 23, NinjaSat began monitoring GS~1826$-$238 in the hard state and continued until the source returned to a steady soft state. During this period, we d…
