A Rome, des milliers de personnes manifestent contre la loi sur la sécurité du gouvernement ultraconservateur de Giorgia Meloni
Ce décret-loi, adopté début avril par le gouvernement et voté jeudi par la Chambre des députés, protège notamment les forces de l’ordre en cas d’accusations de violences policières, et renforce les peines pour certains délits.

Improvement of Solid-Fluid Interaction Scheme in Lattice Boltzmann Immiscible Pseudopotential Models
The pseudopotential model within the Lattice Boltzmann Method (LBM) framework has emerged as a prominent approach in computational fluid dynamics due to its dual strengths in physical intuitiveness and computational tractability. However, when modeling wettability phenomenon, existing solid-fluid interaction schemes exhibit persistent challenges in multi-component immiscible fluid systems, notably manifested through spurious velocity artifacts and unphysical mass-transfer boundary layers. This …

Feeling Guilty Being a c(ai)borg: Navigating the Tensions Between Guilt and Empowerment in AI Use
This paper explores the emotional, ethical and practical dimensions of integrating Artificial Intelligence (AI) into personal and professional workflows, focusing on the concept of feeling guilty as a 'c(ai)borg' - a human augmented by AI. Inspired by Donna Haraway's Cyborg Manifesto, the study explores how AI challenges traditional notions of creativity, originality and intellectual labour. Using an autoethnographic approach, the authors reflect on their year-long experiences with AI tools, re…

Validate the bright Gaia celestial reference frame with new VLBI astrometry of radio stars
There exist inconsistencies between the bright and faint Gaia Celestial Reference Frame 3 (Gaia-CRF3), which manifests as a systematic rotation and needs to be independently estimated then corrected in future data releases. We collected 64 radio stars with VLBI astrometry, of which 16 have new VLBI observations with reference epochs close to Gaia. We estimated the orientation and spin biases of the bright Gaia-CRF3 by comparing VLBI radio star astrometry with their Gaia DR3 counterparts. We als…

Generalised Aichelburg-Sexl and Self-Force for photons
We generalise the Aichelburg-Sexl Stress-Energy-Momentum tensor for massless particles to include motion with angular velocity, introducing tensorial spherical harmonics. Further, we make steps towards the concept of self-force for photons which could manifest as frequency shift.

The ancient Celts upheld values such as truthfulness, loyalty, faithfulness, generosity, hospitality, honesty, righteousness, justice, bravery and courage.
These are part of an honourable life.
We want to try something partly new, using ancient values that meet today's highest moral standards as a compass.
Why not adopt the superior habits of thought and the ancestral knowledge of the druids and go the Nua-Celtic way?
A tree without healthy roots dies and fall…

Simulation of images of protoplanetary disks after collision with free-floating planets
Observational manifestations of disturbances in a protoplanetary disk caused by a collision with a massive planet are studied. It is assumed that the planet moves along a parabolic trajectory that intersects the disk plane near the star. Gas-dynamic simulation is performed using the finite volume method on a long time scale. On its basis, images of the disk observed from the pole and edge-on are constructed in the infrared and submillimeter ranges. A wide range of planet orbit parameters is con…

Approximate half-integer quantization in anomalous planar transport in $d$-wave altermagnets
We investigate anomalous planar transport phenomena in a recently identified class of collinear magnetic materials known as $d$-wave altermagnets. The anomalous planar effects manifest in a configuration when the applied electric field/temperature gradient, magnetic field, and the measured Hall voltage are all co-planar, but the planar magnetic field is instrumental in breaking $\hat{C}_{4z}\hat{\mathcal{T}}$ symmetry of the $d$-wave altermagnet, where $\hat{\mathcal{T}}$ is the time reversal o…

As the head of the Anti-Defamation League, Jonathan Greenblatt has done little to uphold his organization’s claims to fight antisemitism
as the “leading anti-hate organization in the world.”
Instead, he’s shored up the ADL’s role as little more than a fierce pro-Israel lobby group known for defending Israel by attacking its critics.
With no sense of irony, much of this effort manifests as defamatory speech
— at least in the everyday, if not the legal, sense
— by…
