Hierarchical Adversarially-Resilient Multi-Agent Reinforcement Learning for Cyber-Physical Systems Security
Cyber-Physical Systems play a critical role in the infrastructure of various sectors, including manufacturing, energy distribution, and autonomous transportation systems. However, their increasing connectivity renders them highly vulnerable to sophisticated cyber threats, such as adaptive and zero-day attacks, against which traditional security methods like rule-based intrusion detection and single-agent reinforcement learning prove insufficient. To overcome these challenges, this paper introdu…

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…

Manufacturing Tolerances of Non-Planar Coils for an Optimized Tabletop Stellarator
Stellarator coils are known for their complexity and departure from planarity, along with tight manufacturing tolerances in order to achieve the target magnetic field accuracy. These requirements can lead to increased costs and delays in assembly; failure to meet them can compromise the stellarator's performance. Small-scale experiments offer opportunities to develop and benchmark stellarator coil design and evaluation methods more quickly and at lower budget. In this work, we analyze precise 3…

Importantes manifestations à La Haye et Bruxelles pour interpeller les gouvernements sur le « génocide » à Gaza
Quelque 150 000 manifestants ont défilé à La Haye, selon les organisateurs. A Bruxelles, où l’objectif était aussi d’interpeller l’Union européenne, accusée d’inaction, le cortège a réuni 75 000 personnes selon la police, plus de 110 000 d’après les organisateurs.

A novel multi-thickness topology optimization method for balancing structural performance and manufacturability
Topology optimization (TO) in two dimensions often presents a trade-off between structural performance and manufacturability, with unpenalized (variable-thickness) methods yielding superior but complex designs, and penalized (SIMP) methods producing simpler, truss-like structures with compromised performance. This paper introduces a multi-thickness, density-based topology optimization method designed to bridge this gap. The proposed approach guides the design towards a predefined set of discret…

A new Gallup survey of Trump’s first six months in office finds Trump with a 37% approval rating among adults
-- a new low across all pollsters
-- and losing ground on all issues.
Strikingly, Gallup finds that just 38% of Americans approve of how Trump is handling immigration,
and 37% approve of his job on the economy
— the two issues that probably won him the 2024 election.
Trump has lost double digits on handling the federal budget and 6 points on trade…

Developers Insight On Manifest v3 Privacy and Security Webextensions
Webextensions can improve web browser privacy, security, and user experience. The APIs offered by the browser to webextensions affect possible functionality. Currently, Chrome transitions to a modified set of APIs called Manifest v3. This paper studies the challenges and opportunities of Manifest v3 with an in-depth structured qualitative research. Even though some projects observed positive effects, a majority expresses concerns over limited benefits to users, removal of crucial APIs, or the n…

Good Morning #Canada
A Canadian inventor gave Mothers across North America a device that was beneficial and a little scary. We are, of course, talking about the Jolly Jumper, once referred to as "the Canadian Nanny" on a 1957 CBC broadcast. Susan Olivia Poole (1889–1975) was an Indigenous Canadian inventor who created the Jolly Jumper in 1910, but it was not until 1948 that they were produced for the retail market, and patented in 1957. They continue to be manufactured in Ontario by the company that purchased the rights in 1960.
