Sverker Sörlin: Benjamin Dousa, vem slängde dig under bussen?
Sverker Sörlin frågar i ett öppet brev varför Sveriges biståndsminister har stoppat hjälpen till det svältande och sönderbombade Gaza.

SparseDPD: A Sparse Neural Network-based Digital Predistortion FPGA Accelerator for RF Power Amplifier Linearization
Digital predistortion (DPD) is crucial for linearizing radio frequency (RF) power amplifiers (PAs), improving signal integrity and efficiency in wireless systems. Neural network (NN)-based DPD methods surpass traditional polynomial models but face computational challenges limiting their practical deployment. This paper introduces SparseDPD, an FPGA accelerator employing a spatially sparse phase-normalized time-delay neural network (PNTDNN), optimized through unstructured pruning to reduce compu…

Superconductivity in a Chern band: effect of time-reversal-symmetry breaking on superconductivity
Time-reversal-symmetry breaking is generally understood to be detrimental for superconductivity. However, recent experiments found superconductivity emerging out of a normal state showing a finite anomalous Hall effect, indicative of time-reversal-symmetry breaking, in diverse systems from kagome metals, $1T'$-WS$_2$, to twisted MoTe$_2$ and rhombohedral graphene. Motivated by these findings, we study the stability of superconducting orders and the mechanisms that suppress superconductivity in …

$N=1$ Supersymmetry invariance of the Abelian Stueckelberg model
In this paper we investigate the invariance of the Abelian Stueckelberg-like model under gauge and $N=1$ supersymmetric (SUSY) transformations in (3+1) spacetime. We show that the Stueckelberg-like mass term explicitly breaks $N=1$ supersymmetry under the Wess-Zumino (WZ) gauge condition. Nevertheless, we demonstrate that the WZ gauge is not needed in order to construct an action independent of compensating fields, manifestly supersymmetric and gauge invariant.

It would be very interesting to see the RAMS and risk assessment for installing the Butts exhibition at the #WhitechapelGallery.
