This paper studies 3D low-dose computed tomography (CT) imaging. Although various deep learning methods were developed in this context, typically they focus on 2D images and perform denoising due to deblurring for super-resolution separately. Up date, little work was done simultaneous in-plane through-plane deblurring, which is important obtain high-quality CT with lower radiation faster imaging speed. For task, a straightforward method directly train an end-to-end network. However, it...
The selective breaking of the Cβ–O bond has great potential for conversion lignin into high-value aromatic monomers. In present work, we designed a CdS–SH/TiO2 heterojunction photocatalyst efficient bond. surface modification CdS by –SH promoted close contact between catalyst and further Fermi level matching with TiO2. A type-II was constructed CdS–SH TiO2 nanosheets to enhance light absorption range increase separation photogenerated electron–hole pairs, resulting in high catalytic...
Metal implants and other high-density objects in patients introduce severe streaking artifacts CT images, compromising image quality diagnostic performance. Although various methods were developed for metal artifact reduction over the past decades, including latest dual-domain deep networks, remaining are still clinically challenging many cases. Here we extend state-of-the-art network approach into a quad-domain counterpart so that all features sinogram, image, their corresponding Fourier...
In industrial production, the quality, reliability, and precision of parts determine overall quality performance various mechanical equipment. However, existing part defect detection methods have shortcomings in terms feature extraction fusion, leading to issues missed detection. To address this challenge, manuscript proposes a algorithm for (CRD-YOLO) based on improved YOLOv5. Our first aim is increase regional features small targets improve accuracy. manuscript, we design channel- aware...
Abstract This study investigated the dependence of early tropical cyclone (TC) weakening rate in response to an imposed moderate environmental vertical wind shear (VWS) on warm‐core strength and height TC vortex using idealized numerical simulations. Results show that warm core by upper‐level ventilation is primary factor leading VWS. The dominated eddy radial advection air. roughly proportional initial vortex. boundary‐layer shows no relationship with findings suggest some previous diverse...
Due to the complex cross-section and scale effects, surface internal defects are prone occur in Ultra-large-section beam blank. In this study, a coupled model of steel liquid flow heat transfer within 1300×510×140 mm blank mould was established. The results indicate that Single-port SEN reduced activity on meniscus, three-ports led significant high temperature zones re-melting solidified shell flange tip web. four-ports nozzle not only optimizes behavior but also enhances radial uniformity...
This article proposes a compact microstrip four-port dual circularly polarized (CP) multiple-input multiple-output (MIMO) antenna with polarization diversity for Sub-6G band.The proposed MIMO consists of four elements, two which are left-hand circular (LHCP), and the other right-hand (RHCP).The each element is achieved by feed line slotted ground plane rectangular strips.A novel decoupling composed I-shaped II-shaped metal strips cross-connected merged between planes to obtain wide axial...
Abstract Previous studies have investigated how the environmental vertical wind shear (VWS) may trigger asymmetric structure in an initially axisymmetric tropical cyclone (TC) vortex and TC intensity changes response. In this study, possible effect of initial on change response to imposed VWS is based idealized full‐physics model simulations. Results show that can either enhance or suppress weakening VWS. When phase VWS‐induced structure, will be enhanced vice versa. Our finding calls for...

And uncertainty new output also significantly affects stable economic operation integrated microgrid. So how to establish a set optimization model considering photovoltaic (PV) an urgent problem be solved nowadays. Firstly, this paper introduces framework system microgrid containing operator (ESO), analyzes scheduling method...
To achieve uniform cooling and effective homogenization control in ultra-large beam-blank molds necessitates the optimization of submerged-entry-nozzle (SEN) structures. This study employed computational fluid dynamic (CFD) modeling to investigate impact two-port three-port SEN configurations on flow characteristics, free-surface velocities, temperature fields, solidification behaviors. Subsequently, integrating numerical simulations with non-dominated sorting genetic algorithm II (NSGA-II)...
