A mechanism for reduced compression in indirectly driven layered capsule implosions
Physics of Plasmas, 2022 High-yield implosions on the National Ignition Facility rely on maintaining low entropy in the deuterium–tritium fuel, quantified by its adiabat, in order to efficiently couple energy to the hot spot through high compression of the fuel layer. We present

Fast and Efficient Entropy Compression of ALICE Data using ANS Coding [PDF]
EPJ Web of Conferences, 2020 In LHC Run 3, the upgraded ALICE detector will record 50 kHz Pb-Pb collisions using continuous readout. The resulting stream of raw data to be inspected increases to ~ 1 TB/s a hundredfold increase over Run 2 must be processed with a set of lossy and ...

Physical Mechanism of Concrete Damage under Compression [PDF]
Materials, 2019 Although considerable effort has been taken regarding concrete damage, the physical mechanism of concrete damage under compression remains unknown. This paper presents, for the first time, the physical reality of the damage of concrete under compression in the view of statistical and probabilistic information (SPI) at the mesoscale.

Data‐driven performance metrics for neural network learning
International Journal of Adaptive Control and Signal Processing, EarlyView., 2023 Summary Effectiveness of data‐driven neural learning in terms of both local mimima trapping and convergence rate is addressed. Such issues are investigated in a case study involving the training of one‐hidden‐layer feedforward neural networks with the extended Kalman filter, which reduces the search for the optimal network parameters to a state ...

Enabling Lightweight Fine-tuning for Pre-trained Language Model Compression based on Matrix Product Operators [PDF]
Annual Meeting of the Association for Computational Linguistics, 2021 This paper presents a novel pre-trained language models (PLM) compression approach based on the matrix product operator (short as MPO) from quantum many-body physics.

Physics of compressed baryonic matter [PDF]
Journal of Physics: Conference Series, 2013 The experimental investigation of the QCD phase diagram with heavy ion collisions is an ongoing intense research topic at international accelerator facilities since the 80's and recently got new boost with the first results from the LHC experiments. Together with results from the top RHIC energies they investigate partonic matter in every detail at ...

Physics‐Informed Deep‐Learning For Elasticity: Forward, Inverse, and Mixed Problems
Advancement of science, 2023 Elastography is a medical imaging technique used to measure the elasticity of tissues by comparing ultrasound signals before and after a light compression. The lateral resolution of ultrasound is much inferior to the axial resolution.

Hot-mode accretion and the physics of thin-disk galaxy formation [PDF]
Monthly notices of the Royal Astronomical Society, 2022 We use FIRE simulations to study disk formation in z ∼ 0, Milky Way-mass galaxies, and conclude that a key ingredient for the formation of thin stellar disks is the ability for accreting gas to develop an aligned angular momentum distribution via ...
