Comparative evaluation of supervised and unsupervised deep learning strategies for denoising hyperpolarized ¹²⁹Xe lung MRI. [PDF]

Magn Reson Med
Abstract Purpose Reduced signal‐to‐noise ratio (SNR) in hyperpolarized 129Xe MR images can affect accurate quantification for research and diagnostic evaluations. Thus, this study explores the application of supervised deep learning (DL) denoising, traditional (Trad) and Noise2Noise (N2N) and unsupervised Noise2void (N2V) approaches for 129Xe MR ...

Vapor Deposition of Polymer Structures: From 2D Surface Coatings and Surface Microstructures to 3D Building Blocks and Structural Monoliths. [PDF]

Macromol Rapid Commun
This review discusses the progress of vapor‐deposited polymer structures, from simple thin films and surface microstructures to complex 3D architectures and monoliths. It covers fabrication methods, polymerization mechanisms, and processes for fabricating these structures. The applications of these polymers are discussed, focusing on device integration

A kilonova following a long-duration gamma-ray burst at 350 Mpc [PDF]

Nature, 2022
Gamma-ray bursts (GRBs) are divided into two populations1,2; long GRBs that derive from the core collapse of massive stars (for example, ref. 3) and short GRBs that form in the merger of two compact objects4,5.

Scanning nitrogen-vacancy magnetometry down to 350 mK [PDF]

Applied Physics Letters, 2022
We report on the implementation of a scanning nitrogen-vacancy (NV) magnetometer in a dry dilution refrigerator. Using pulsed optically detected magnetic resonance combined with efficient microwave delivery through a co-planar waveguide, we reach a base ...

Amplitude death, oscillation death, and stable coexistence in a pair of VDP oscillators with direct–indirect coupling

Electronic Research Archive, 2023
In this paper, we investigated the dynamics of a pair of VDP (Van der Pol) oscillators with direct-indirect coupling, which is described by five first-order differential equations. The system presented three types of equilibria including HSS (homogeneous
