When Forgetting Triggers Backdoors: A Clean Unlearning Attack
Machine unlearning has emerged as a key component in ensuring ``Right to be Forgotten'', enabling the removal of specific data points from trained models. However, even when the unlearning is performed without poisoning the forget-set (clean unlearning), it can be exploited for stealthy attacks that existing defenses struggle to detect. In this paper, we propose a novel {\em clean} backdoor attack that exploits both the model learning phase and the subsequent unlearning requests. Unlike traditi…

Af en eller anden årsag kom jeg lige i tanke om de Castus frugtstænger som jeg sidst spiste for ~20 år siden.
Hold kæft hvor kunne jeg godt spise sådan en lige nu.

Lawmakers push for ban on dangerous food packaging: 'We must curb anything that will negatively impact the health and environment of the citizens'
Following similar bans in Africa, one Nigerian state may soon add itself to the list of locations that no longer allow Styrofoam for food packaging.

En ny studie påstås bevisa att en massa populära råd på internet vid endometrios nu är bevisade att fungera men studien är en dåligt utförd enkätstudie som egentligen inte svarar på någonting mer än vad som är populärt att testa just nu

Así va mi proyecto de actualización del router WiFi en mi departamento. Tuve que "entrar a picar" para instalar un pequeño extractor noctua, muy silencioso, en la tapa de la carcasa. También hice un pequeño script para controlar la velocidad y así quede aún mšs silencioso.

if i can hold a conversation with you, you're in, cause for me that's rare. anything else genuinely doesn't matter to me unless you yourself are hurting someone else and won't even entertain change, the other "in" that is my connection with you. ive developed a sense of what to expect and what's rare in people by seeing all the different types there are. and im absolutely nicer than i should be to everyone, but most people are insincere or too far the other way …

»Blei und Antimon werden während des Essens aufgenommen durch mangelhaft gereinigte Hände und manche Unsitten in den Betrieben. Der Schriftgießer sollte es unbedingt vermeiden, Eßwaren ohne gründliche Säuberung der Hände anzufassen, […]; auf alle Fälle ist während der Arbeit das Rauchen zu unterlassen, weil dabei eine gesteigerte Einatmung stattfindet und das angekaute Zigaretten- oder Zigarrenende als Staubfänger wirkt.«

Emergent anisotropic three-phase order in critically doped superconducting diamond films
Two decades since its discovery, superconducting heavily boron-doped diamond (HBDD) still presents unresolved fundamental questions whose resolution is relevant to the development of this material for quantum technologies. We use electrical magnetotransport measurements of critically-doped homoepitaxial single crystal HBDD films to reveal signatures of intrinsic (electronic) granular superconductivity. By studying the dependence of electrical resistivity on temperature and magnetic field vector…

Identity and Access Management for the Computing Continuum
The computing continuum introduces new challenges for access control due to its dynamic, distributed, and heterogeneous nature. In this paper, we propose a Zero-Trust (ZT) access control solution that leverages decentralized identification and authentication mechanisms based on Decentralized Identifiers (DIDs) and Verifiable Credentials (VCs). Additionally, we employ Relationship-Based Access Control (ReBAC) to define policies that capture the evolving trust relationships inherent in the contin…

X-ray Polarization Detection of the Pulsar Wind Nebula in G21.5-0.9 with IXPE
We present the X-ray polarization observation of G21.5-0.9, a young Galactic supernova remnant (SNR), conducted with the Imaging X-ray Polarimetry Explorer (IXPE) in October 2023, with a total livetime of approximately 837 ks. Using different analysis methods, such as a space-integrated study of the entire region of the PWN and a space-resolved polarization map, we detect significant polarization from the pulsar wind nebula (PWN) at the center of the SNR, with an average polarization degree of …
