Fast-Neutron Irradiation Effect in Heteroepitaxial $\beta$-Ga$_2$O$_3$ Schottky Diodes Fabricated on Low-Cost Sapphire Substrates

Announce Type: new Abstract: In this work, we investigate the response of Ni/$\beta$-Ga$_2$O$_3$ Schottky barrier diodes fabricated on c-plane sapphire to fast-neutron irradiation up to a fluence of $1\times10^{15}$ n$\cdot$cm$^{-2}$. The LPCVD-grown heteroepitaxial structure consists of an unintentionally doped buffer, an n$^{+}$ contact layer, and an n-type drift layer, with mesa isolation realized by plasma-free Ga-assisted LPCVD etching. Prior to irradiation, the devices exhibit a...

Zero-Shot Polygon Matching with Pre-trained Models for Pose Estimation and Polygon Cloud from Challenging Stereo

Announce Type: replace Abstract: While stereo matching has achieved maturity for 0D point and 1D line primitives, establishing correspondences for 2D polygons remains largely unexplored due to challenges including disparity discontinuity, scale variation, training dependency, and poor generalization, limiting downstream tasks such as pose estimation and 3D reconstruction. To address these issues, we are the first to propose a Zero-shot Polygon Matching paradigm with Pre-trained Models (i.e.,...

Former election clerk Tina Peters released after Trump pressure campaign

Former election clerk Tina Peters released after Trump pressure campaign Peters had been sentenced to nine years in state prison after allowing an unauthorised person access to Colorado state voting machines. Tina Peters, a former Colorado official convicted of allowing election machine tampering, has been released from state prison following a pressure campaign by United States President Donald Trump. As Peters left state prison on Monday, Colorado’s Secretary of State Jena Griswold issued...

Texas teens accused of using dating apps to lure young men into violent robberies that left one victim shot

Two Texas teenagers are accused of using online dating platforms to lure young men into violent robberies that left one victim pistol-whipped and a 15-year-old boy shot four times, authorities said. Alyssa Canul, 17, was arrested on May 27 in Universal City, near San Antonio, and charged with two counts of aggravated robbery, according to Universal City officials and Bexar County arrest records. Authorities say she worked alongside her boyfriend, Joseph Anthony Aguilar, 18, who was arrested...

Would you ride in Waymo's new Ojai robotaxi?

Getting into a car with no one behind the wheel can be a little weird the first time. You know the car is supposed to drive itself, but part of you no doubt may still feel uneasy. Waymo is trying to make that moment feel less anxious with its new Ojai robotaxi.

The American Missile Crisis

Recent global conflicts, from Russia and Ukraine to Iran and Israel, have seen a resurgent awareness of the frailty of US munitions stock, which has been drawn down by both direct and indirect involvement in these events. While exact stockpile volumes are not disclosed, it is estimated that supplies of US warheads and the missiles that carry them have declined by nearly an order of magnitude since their peak during the Cuban Missile Crisis. Analysts have estimated that in the event of a...

MesaNet: Sequence Modeling by Locally Optimal Test-Time Training

arXiv:2506.05233v2 Announce Type: replace Abstract: Sequence modeling is currently dominated by causal transformer architectures that use softmax self-attention. Although widely adopted, transformers require scaling memory and compute linearly during inference. A recent stream of work linearized the softmax operation, resulting in powerful recurrent neural network (RNN) models with constant memory and compute costs such as DeltaNet, Mamba or xLSTM.
