Studies on the effect of low-fluence proton and neutron irradiation on n-type LGADs
The presented study investigates the effects of low fluences from $5\times10^{12}$ up to $1\times10^{14}$ particles/cm$^{2}$ of 60MeV proton and neutron irradiation on n-type Low Gain Avalanche Detectors (nLGADs). An nLGAD is a silicon sensor with a highly doped gain layer that enables controlled charge multiplication via impact ionization. In contrast to the well-established p-type LGADs for high-energy physics (HEP) applications, nLGADs are optimized for the detection of low-penetrating parti…

Live-streaming journalist deported to El Salvador after months in ICE custody
The reporter was arrested while reporting from a “No Kings Day” protest in June and was deported on Friday — a major blow to press freedoms, say groups including the ACLU.

Revisiting Cases 2 and 11 of the Map Color Theorem
In 1968, Ringel and Youngs solved the remaining cases of the orientable Map Color Theorem by finding genus embeddings of the complete graphs $K_n$, for sufficiently large $n \equiv 2, 8, 11 \pmod{12}$. Following the approach previously explored by the author for $n \equiv 8 \pmod{12}$, we aim to streamline their constructions for $n \equiv 2, 11 \pmod{12}$ by finding families of current graphs with simpler patterns for the arc labelings.

Angel’s Egg (1985)
Absolutely beautiful. Not sure if I understood it, nor do I think I needed to to enjoy it.
The guy next to me in the cinema fell asleep in 3 minutes and slept through most of the movie, fortunately no snoring.
I have mixed feelings about 4K restoration, because while mostly it helped show off the meticulousness of the animation at times where it happened to be only near perfect, proved to be distracting.

Stability of surfactant-laden double-layered viscoelastic fluids flowing over an inclined plane
The linear dynamics and instability mechanisms of double-layered weakly viscoelastic fluid flowing over an inclined plane are analyzed in the presence of insoluble surfactant at both the free surface and interface. The constitutive equation of the non-Newtonian flow field follows the rheological property of Walters' $B^{''}$ model. The Orr-Sommerfeld-type boundary value problem is derived using the classical normal-mode approach and numerically solved within the framework of the Chebyshev spect…

Structuring Polarization States of Light in Space and Time
The spatiotemporal sculpturing of light beams with arbitrary phase and polarization topologies has garnered significant attention in recent years due to its potential to advance optical technologies and reveal novel physical phenomena. Examples of spatiotemporal beams include space-time wave packets, flying donuts, tilted pulse fronts, X-waves, Airy pulses, and spatiotemporal optical vortices. Here, we introduce and demonstrate a new class of spatiotemporal polarization states of light. We prop…

1/2 In a piece about Canadian politics, probably not of interest to outsiders, I suspect this will amuse many:
“Trump’s [team] are every bit the … “Bad Boy” Detroit Pistons of the late 80s … Trump is peak Bill Laimbeer, sneering and fouling everything in sight. JD Vance is Dennis Rodman, an Energizer bunny clearing the boards. And Stephen Miller is Isaiah Thomas, the floor general weaving through defences and chirping at his opponents with an insouciant mug begging to be slapped.”
