Focusing the Axion Wind with Ferrite Flux Concentrators
Axion dark matter may couple to fermion spins through an effective oscillating magnetic field, the ``axion wind". Existing approaches for detecting axion wind via axion-electron coupling $g_{ae}$ face sensitivity limitations due to the extremely weak pseudomagnetic field generated, typically a few times $10^{-18}$ tesla for $g_{ae} \sim 10^{-10}$. We propose to use ferrimagnetic flux concentrators to amplify the pseudomagnetic field into a genuine magnetic field, which can then be measured usin…

Garbage. Ppl pay for this?
My prompt was `Edward Hopper's American Gothic but with two robots` and it didn't even include a pitchfork.
#microsoft

American Robot Gothic attempt 1: its a farm house ok. The two robots look like the one from Lost In Space a bit, all metallic. There's some humanoid wearing a sunhat in the background; is he their master? Is he enslaved? Is he a Solaran from Asimov's Robot/Foundation novels and his mutant telekenesis is how the Robots are powered?
American Robot Gothic #2 - a farmhouse (ok) but against a backdrop of oil derricks (fitting) with two Iron Giant style monstrosities who look like they're ready to stomp the house for being woke. What looks like an Edsel is in the driveway. Some weird abstract porch chairs sit... err float.. disjointedly on the porch. The Iron couple's robot progeny play "RoboCops and Humans" on one side of the porch. The light is that of dusk, about the time that the street lights would come on and all good ro…
American Robot Gothic attempt #3: farmhouse check. Someone is burning insurance papers in the basement furnace as black smoke eminates from the chimney.. and also from the old style TV antennae for some reason. There are two "tin can man" style robots with red eyes and antennae ears in the foreground with exposed hoses and articulations at joints, but they're not standing side by side and neither has a pitchfork. The SPirit of St. Lois flies in the sky along with... Skylab?! for some reason…
American Robot Gothic pathetic attempt 4: Another farmhouse (ok). Anthropromorphized robots stand in the foreground (one wears a metal dress). Again, no pitchforks. A masonic temple and... The Sears building ? appear in the background. The two (rightful) human owners of the house sit smug in their rocking chairs looking on as another human - who looks like Elon Musk with a Ron Jeremy eyebrows and mustache roars off in a 1937 Ford Two Door roadster, like he's the evil banker that just forecl…

The American Civil Liberties Union of South Carolina filed a lawsuit Friday against Clemson University,
accusing the school of violating the First Amendment by firing a faculty member over a Facebook post criticizing the late conservative commentator Charlie Kirk.
The complaint, filed in U.S. District Court on behalf of former assistant professor
Joshua Bregy,
seeks his reinstatement, corrections to his personnel record and monetary damages.

El mšs grande de los frontman en la historia del rock nació un día como hoy, 5 de septiembre, hace 79 años. La voz de Queen, Freddie Mercury, quien falleció el 45 años en 1991. Su voz y presencia en el escenario fueron únicas.
#FreddieMercury #CumpleañosRockero

Una imagen de Freddie Mercury, el icónico vocalista de Queen, actuando en un escenario. Se le ve de medio cuerpo, mirando ligeramente hacia arriba y a la derecha con la boca abierta, en pleno canto. Lleva su famosa chaqueta amarilla de estilo militar con hombreras y franjas horizontales doradas o plateadas. Debajo, viste una camiseta blanca y un cinturón blanco con una hebilla dorada. Sostiene su característico micrófono con el soporte cortado en la mano izquierda. Su cabello es oscuro y luce s…

Quantum Markov Chain Monte Carlo for Cosmological Functions
We present an implementation of Quantum Computing for a Markov Chain Monte Carlo method with an application to cosmological functions, to derive posterior distributions from cosmological probes. The algorithm proposes new steps in the parameter space via a quantum circuit whose resulting statevector provides the components of the shift vector. The proposed point is accepted or rejected via the classical Metropolis-Hastings acceptance method. The advantage of this hybrid quantum approach is that…
