We aimed to evaluate the performance of newly developed deep learning Radiomics elastography (DLRE) for assessing liver fibrosis stages. DLRE adopts radiomic strategy quantitative analysis heterogeneity in two-dimensional shear wave (2D-SWE) images.A prospective multicentre study was conducted assess its accuracy patients with chronic hepatitis B, comparison 2D-SWE, aspartate transaminase-to-platelet ratio index and based on four factors, by using biopsy as reference standard. Its robustness...
Purpose To investigate the diagnostic performance of two-dimensional (2D) shear-wave elastography (SWE) in chronic hepatitis B. Materials and Methods This prospective multicenter study from January 2015 to 2016 was conducted at 12 hospitals included 654 participants with B who had undergone liver biopsy 2D SWE examination. Participants were divided into infection groups. The compared aspartate amino transferase–to-platelet ratio index (APRI), Fibrosis-4 (FIB-4), transient (TE) by using a...
With the rapid development of railways, especially high-speed there is an increasingly urgent demand for new wireless communication system railways. Taking mature 5G technology as opportunity, 5G-railways (5G-R) have been widely regarded a solution to meet diversified demands railway communications.

The underwent LSM STE supersonic shear imaging (SSI) or STQ acoustic radiation force impulse (ARFI). biopsy both STE/STQ. areas under receiver operating characteristic curves (AUCs)...
In recent years, machine-to-machine (M2M) communications have attracted great attentions from both academia and industry. M2M communication systems, machine type devices (MTCDs) are capable of communicating with each other intelligently under highly reduced human interventions. Although diverse types services expected to be supported for MTCDs, various quality service (QoS) requirements network states pose difficulties challenges the resource allocation clustering schemes systems. this...
Reconfigurable intelligent surface (RIS) emerges as an efficient and promising technology for the next wireless generation networks has attracted a lot of attention owing to capability extending coverage by reflecting signals toward targeted receivers. In this paper, we consider RIS-assisted high-speed train (HST) communication system enhance improve probability. First, performance downlink single-input-single-output is investigated, closed-form expression probability derived. Moreover,...
Heterogeneous machine-to-machine communication networks (HMCNs) are expected to provide ubiquitous connectivity for machine type devices (MTCDs) with reduced human intervention. Although various types of services will be supported MTCDs, diverse quality service requirements and network characteristics pose challenges difficulties the resource allocation, cell selection, random access schemes HMCNs. In this paper, we propose a joint class barring (ACB), allocation algorithm To achieve...
High-speed train (HST) has garnered significant attention from both academia and industry due to the rapid development of railways worldwide. Millimeter wave (mmWave) communication, known for its large bandwidth is an effective way address performance bottlenecks in cellular network based HST wireless communication systems. However, mmWave signals suffer path loss when traversing carriage, posing substantial challenges networks. To this issue, reconfigurable intelligent surfaces (RIS) have...
