Medium-induced coherent gluon radiation for $2\to 2$ processes with general kinematics
High-energy proton-nucleus (pA) collisions have provided various clues for the role of cold nuclear matter effects in hadron production. In particular, multiple rescatterings of an incoming parton by the nuclear target are known to induce the radiation of many soft gluons, with...
PP-Tac: Paper Picking Using Tactile Feedback in Dexterous Robotic Hands
Robots are increasingly envisioned as human companions, assisting with everyday tasks that often involve manipulating deformable objects. Although recent advances in robotic hardware and embodied AI have expanded their capabilities, current systems still struggle with handling thin, flat, and deformable objects such...
Small Alfvén Number Limit for the Global-in-time Solutions of Incompressible MHD Equations with General Initial Data
The small Alfv\’en number (denoted by $\varepsilon$) limit (one type of large parameter limits, i.e. singular limits) in magnetohydrodynamic (abbr. MHD) equations was first proposed by Klainerman–May and (Comm. Pure Appl. Math. 34: 481–524, 1981). Recently Ju–Wang–Xu mathematically verified that the \emph{local-in-time}...
Photo-generated charge-transfer excitons in NiO revealed by ultrafast time-resolved resonant inelastic x-ray scattering
Strong electronic correlation can lead to insulating behavior and to the opening of large optical gaps, even in materials with partly filled valence shells. Although the non-equilibrium optical response encodes both local (almost atomic) and collective (long range) responses, optical spectroscopy is...
A Time Series Dataset of NIR Spectra and RGB and NIR-HSI Images of the Barley Germination Process
We provide an open-source dataset of RGB and NIR-HSI (near-infrared hyperspectral imaging) images with associated segmentation masks and NIR spectra of 2242 individual malting barley kernels. We imaged every kernel pre-exposure to moisture and every 24 hours after exposure to moisture for...
MHD Simulations Preliminarily Predict The Habitability and Radio Emission of TRAPPIST-1e
As the closest Earth-like exoplanet within the habitable zone of the M-dwarf star TRAPPIST-1, TRAPPIST-1e exhibits a magnetic field topology that is dependent on space weather conditions. Variations in these conditions influence its habitability and contribute to its radio emissions. Our objective...
Backslash: Rate Constrained Optimized Training of Large Language Models
The rapid advancement of large-language models (LLMs) has driven extensive research into parameter compression after training has been completed, yet compression during the training phase remains largely unexplored. In this work, we introduce Rate-Constrained Training (Backslash), a novel training-time compression approach based...
Quantum walk search for exceptional configurations on one- and two-dimensional lattice with extra long-range edges of HN4 network
There exist several types of configurations of marked vertices, referred to as the exceptional configurations, on one- and two-dimensional periodic lattices with additional long-range edges of the HN4 network, which are challenging to find using discrete-time quantum walk algorithms. In this article,...
Anomalies in Muon-Induced Neutron Emissions from Pb
This paper analyses neutron multiplicity spectra from massive targets at depths of 3, 40, 210, 583, 1166, and 4000 m.w.e. The measurements, conducted between 2001 and 2024, utilised three experimental setups with either 14 or 60 He-3 neutron detectors and lead (Pb)...
Representation Learning via Non-Contrastive Mutual Information
Labeling data is often very time consuming and expensive, leaving us with a majority of unlabeled data. Self-supervised representation learning methods such as SimCLR (Chen et al., 2020) or BYOL (Grill et al., 2020) have been very successful at learning meaningful latent...
