Numerical analysis of a finite volume method for a 1-D wave equation with non smooth wave speed and localized Kelvin-Voigt damping
arXiv:2502.19947v3 Announce Type: replace-cross Abstract: In this paper, we study the numerical solution of an elastic/viscoelastic wave equation with non smooth wave speed and internal localized distributed Kelvin-Voigt damping acting faraway from the boundary. Our method is based on the Finite Volume Method (FVM) and we are interested in deriving the stability estimates and the convergence of the numerical solution to the continuous one. Numerical experiments are performed to confirm the...
Scientists break 30-year superconductivity record at normal pressure
Scientists at the University of Houston have shattered a long-standing superconductivity record, creating a material that can conduct electricity with zero resistance at the highest temperature ever achieved under normal pressure conditions. Their breakthrough pushes superconductivity to 151 Kelvin (minus 122°C), beating a record that stood for more than 30 years.
The Hypocrisy of the Democrats Who Defend Graham Platner
Title: The Hypocrisy of the Democrats Who Defend Graham Platner For decades, Nazism and the anti-Semitism underlying it have marked zero on the Kelvin scale of villainy—the metric against which all other forms of evil are compared. This is so well understood that we now have cultural phenomena such as Godwin’s Law, the theory that online debates inevitably lead to Nazi comparisons, and the “everything I don’t like is Hitler” meme. But their existence proves the point: If one wishes to say that something is irredeemably bad, Nazis are the benchmark, the absolute.Yet recently this understanding seems to have grown less universal. Nazi symbolism and more modern versions of the ancient conspiracy theories behind this intolerable ideology have found a degree of toleration within American political movements desperate for shortsighted victories. The underlying hatred that, among other things, motivated the killing of more than a third of all the Jews on the planet eight decades ago is viewed no longer as unacceptable, but rather somewhere on a scale of “problematic” issues that can be either explained away or ignored.The most recent case is that of Graham Platner, the 41-year-old Democrat who is hoping to unseat Senator Susan Collins in Maine. Platner has a unique personal
Saturday Citations: Failure to launch; cellular mortality; heavy weather
May 30, 2026 report Saturday Citations: Failure to launch; cellular mortality; heavy weather Chris Packham Author Lisa Lock Scientific Editor Robert Egan Associate Editor Highlights from the last week of May, 2026: A key climate tipping point is disrupting the Arctic Ocean food chain (more of a lowlight, I guess). Scuba-diving tourism may not be the benefit to coral reef systems that we once thought, and might actually be unsustainable.
Numerical Study of Dissipative Weak Solutions for the Euler Equations of Gas Dynamics
arXiv:2601.17452v3 Announce Type: replace Abstract: We study dissipative weak (DW) solutions of the Euler equations of gas dynamics using the first-, second-, third-, fifth-, seventh-, and ninth-order local characteristic decomposition-based central-upwind (LCDCU), low-dissipation central-upwind (LDCU), and viscous finite volume (VFV) methods, whose higher-order extensions are obtained via the framework of the alternative weighted essentially non-oscillatory (A-WENO) schemes. These methods...
Nonspherical gas bubble dynamics in viscoelastic soft materials
arXiv:2606.07817v2 Announce Type: new Abstract: Nonspherical gas bubble dynamics in viscoelastic materials influence the stress transmission and energy dissipation of their surroundings and are difficult to predict. Their accurate prediction is essential in applications ranging from biomedical procedures to high-strain-rate rheological measurements. However, existing models do not sufficiently capture the nonspherical rotational dynamics.
Decades of Effort Restore Steelhead and Salmon Passage on Alameda Creek
Last year, California Trout and Pacific Gas & Electric removed the final barrier to fish passage on California’s Alameda Creek with funding from NOAA Fisheries’ Office of Habitat Conservation. For the first time in 50 years, threatened Central California Coast steelhead and other migratory fish can reach spawning grounds and juvenile rearing habitat in the upper watershed. Construction crews relocated a Pacific Gas & Electric (PG&E) natural gas pipeline and removed its concrete covering.
