Evidence of TeV gamma-ray emission from the nearby starburst galaxy NGC 253

, 2003
TeV gamma-rays were recently detected from the nearby normal spiral galaxy NGC 253 (Itoh et al., 2002). Observations to detect the Cherenkov light images initiated by gamma-rays from the direction of NGC 253 were carried out in 2000 and 2001 over a total

Exceptional Flux Compactifications [PDF]

, 2012
We consider type II (non-)geometric flux backgrounds in the absence of brane sources, and construct their explicit embedding into maximal gauged D=4 supergravity.

The Concordance Cosmic Star Formation Rate: Implications from and for the Supernova Neutrino and Gamma Ray Backgrounds

, 2005
We constrain the Cosmic Star Formation Rate (CSFR) by requiring that massive stars produce the observed UV, optical, and IR light while at the same time not overproduce the Diffuse Supernova Neutrino Background as bounded by Super-Kamiokande.

Instanton fermionic zero mode at finite temperature and chemical potential

, 2011
In QCD the spontaneous breaking of chiral symmetry and the U(1) axial anomaly can be understood considering instantons as the gauge configurations mediating quark-quark interaction.

Transistor‐Level Activation Functions via Two‐Gate Designs: From Analog Sigmoid and Gaussian Control to Real‐Time Hardware Demonstrations

Advanced Materials, EarlyView.
Screen gate‐based transistors are presented, enabling tunable analog sigmoid and Gaussian activations. The SA‐transistor improves MRI classification accuracy, while the GA‐transistor supports precise Gaussian kernel tuning for forecasting. Both functions are implemented in a single device, offering compact, energy‐efficient analog AI processing ...

Host‐Directed Antiviral Activity of SB2960 Through Selective Induction and Remodeling of Stress Granules

Advanced Science, EarlyView.
Amid the ongoing threat of emerging viral pathogens, host‐directed antivirals offer a strategy to overcome viral mutation and drug resistance. SB2960, a small‐molecule inducer of stress granules (SGs), exhibits potent broad‐spectrum antiviral activity with minimal cytotoxicity.
