But absurdity is no impediment to religious belief—credo quia absurdum. Working mostly off-campus, I noticed no real change in my own university until the BLM-riot-inspired anti-racism crisis of 2020, when I found that academe, originally a place for the free exchange of ideas, had become almost unrecognizable. Higher education has begun a transformation along the same lines as the 1966 “Cultural Revolution” in Maoist China.

Ukraine's energy revolution is being powered by women leaders and local communities. Through initiatives like 100 Solar Schools and 50 Solar Hospitals, the country is building resilience with decentralized renewable systems—solar panels and batteries that keep critical infrastructure running even during conflict. This shift toward energy independence shows how sustainable power can be a security strategy.

Abstract: Thermodynamic nonequilibrium effects play a central role in momentum and energy transport in compressible flows. In conventional BGK kinetic models, the relaxation time $\tau$ is taken as a constant, which neglects the dependence of the relaxation process on local macroscopic states. To overcome this limitation, we develop a discrete Boltzmann model with a density- and temperature-dependent power-law relaxation time, termed DTRT-DBM, in which $\tau=\tau_0(\rho/\rho_0)^a(T/T_0)^b$. This formulation extends the discrete Boltzmann framework to flows with spatially varying nonequilibrium intensity. The model is validated by the Sod shock tube and by analytical solutions for viscous stress and heat flux, demonstrating accurate recovery of both macroscopic wave structures and nonequilibrium quantities across shock waves, rarefaction waves, and contact discontinuities. On this basis, phase diagrams of viscous stress and heat flux are constructed to examine how these quantities depend on the power-law exponents $a$ and $b$. The extrema of these quantities depend exponentially on the model parameters and exhibit regime-dependent behaviour. The roles of $a$ and $b$ are not symmetric: the nonequilibrium response is more sensitive to $a$ when density gradients dominate, but more sensitive to $b$ when temperature gradients dominate. Within the parameter range and flow configurations examined here, higher-order viscous stress increases the growth rate of the total viscous-stress extremum, whereas higher-order heat flux reduces the growth rate of the total heat-flux extremum. These results show that the proposed model can capture different higher-order nonequilibrium responses in compressible flows and provides a framework for the modelling and analysis of multiscale nonequilibrium processes.

Under new European Union rules, businesses must prioritise keeping unsold clothing or shoes in use by selling them (including through discounts or alternative markets), donating them to charities or social enterprises, or preparing them for reuse (repairing, refurbishing or remanufacturing).
Destruction will be allowed only under specified circumstances and must be carried out in accordance with the waste treatment hierarchy, giving priority to recycling

Does anyone have any decent EDR running on an Apple Neo? Logging? I have a small nonprofit org that wants to roll out a fresh fleet of 15 Neos and the arm64 chip in the Neo isn't the same series as the M. I'm looking for actual A18 Pro / MacBook Neo validation, not "it should work" because I've already got Claude telling me "it shoudl work fine" and that reality is not manifesting for an MSP I know working with this issue.

So I picked up a #Skmei 2514 as well recently. This is a very close copy of the Casio A168WEHA-9AEF. With recent reports being that Casio is killing off the A168 altogether and with this variant already being discontinued for a while I can feel OK with this purchase. Yes you can find a few places with some old stock or well maintained second hand copies, but they would generate Casio no money …

❝Criminalizing dissent isn’t a sideshow. It’s central to the plan. They want to stop you from taking to the streets in massive numbers if and when they take illegal actions to keep the Republican Party in power. They are using these bogus indictments to lay the foundation for the solution that Vice President JD Vance proposed for Minneapolis back in January — to invoke the Insurrection Act and send in tanks.❞

As a fan of traditional machine learning research, I’ll just register here my sadness and discontent that things are going this way. Time was that an effort like this would follow stringent ethical rules for research involving humans that would never ever allow this kind of phony consent theater, would go through a review board •with actual teeth•, would not involve offloading raw personal data to commercial vendors who have the power to slurp it up and repurpose it, would result in a narrowly purposed-tuned model answering to the ethical parameters of the study, would not leave the barn doors wide open to endless open-ended use of personal data…I could go on.

High-Order ADER-DG Hydrodynamics with ExaHyPE: Implementation, Validation, and Astrophysical Benchmarking
Andr\'es Mauricio Su\'arez Mantilla, Leonardo Casta\~neda Colorado
arxiv.org/abs/2605.17132 arxiv.org/pdf/2605.17132 arxiv.org/html/2605.17132
arXiv:2605.17132v1 Announce Type: new
Abstract: We describe a high-order ADER-DG solver for the compressible Euler equations within the ExaHyPE framework. The implementation combines a high-order ADER-DG polynomial representation, a local space-time DG predictor, adaptive mesh refinement, and an a posteriori subcell finite-volume limiter. We test the code on a deliberately mixed set of one- and two-dimensional problems: a strong-shock Sod-type problem, the Shu-Osher shock-entropy interaction, the Woodward-Colella blast wave, a contact-driven vortex sheet, and a shock-interface interaction. The one-dimensional cases recover the expected Euler wave patterns and show clear order-dependent gains in smooth and oscillatory regions. The two-dimensional cases probe a different part of the method, namely contact preservation, shear-driven roll-up, baroclinic vorticity deposition, and Richtmyer-Meshkov-type growth. In these tests the high-order update gives the expected resolution away from discontinuities, whereas the subcell limiter keeps the calculation stable near shocks and steep interfaces. The resulting code provides a reproducible ExaHyPE implementation for idealised inviscid, non-relativistic flows in which shocks, contacts, and multidimensional interfaces are the dominant features.
