Acute pulmonary embolism represents the third most prevalent cardiovascular pathology, following coronary heart disease and hypertension. Its untreated mortality rate is as high 20–30%, which a significant threat to patient survival. In view of current lack real-time monitoring techniques for acute embolism, this study primarily investigates potential pulsatility electrical impedance tomography (EIT) technique detection through collection imaging pulsatile signal blood flow. A...
In this letter, we propose to identify line-of-sight (LOS) and non-line-of-sight (NLOS) conditions based on a convolutional neural network (CNN) in urban 3-D massive MIMO systems. The proposed method includes two parts. the first part, given that paths spread differently time domain, combine normalized tap energy distribution each antenna utilizing sounding reference signals construct coordinated matrix. second train CNN analyze matrix LOS/NLOS conditions. A channel model is considered our...
Objective. This study focuses on the identification of risk factors, classification stroke level, and evaluation importance interactions various patient characteristics using cohort data from Second Hospital Lanzhou University. Methodology. Risk factors are identified by relationships between response, as well ranking characteristics. Then, after discarding negligible some well-known multicategorical algorithms used to predict level stroke. In addition, Shapley additive explanation method...
In the letter, we propose to estimate uplink channel in urban 3-D MIMO systems utilizing denoising convolutional neuron networks (DnCNNs), which is recently proposed and has succeeded tackling with image tasks computer vision. To process complex numbers estimation (CE), based on DnCNN (CDnCNN), a variant of DnCNN, simplified (S-DnCNN) CE. S-DnCNN CE includes two major parts. first part, frequency impulses are rearranged form feature maps. second considering practical latency constraints,...
Identifying the transmission status as line-of-sight (LOS) and non-line-of-sight (NLOS) is of importance for 3D Massive Multiple-Input Multiple-Output (MIMO) systems, which one core technology to improve 5G New Radio (NR) capacity spectral efficiency. If identification could be accurate possible, positioning systems adaptive radio like cognitive radios can increase their performances significantly. This paper presents an improved algorithm LOS/NLOS in MIMO systems. By fully considering...
To satisfy the explosive growth of data in large-scale centers, where redundant arrays independent disks (RAIDs), especially RAID-5, are widely deployed, effective storage scaling and disk expansion methods desired. However, a way to reduce migration overhead maintain reliability original RAID major concerns scaling. address these problems, we propose new scheme, H-Scale, achieve fast via hybrid stripe layouts. H-Scale takes advantage loose restriction structures choose migrated create...
In Time Domain Duplex (TDD) massive MIMO systems, multi-group multi-casting becomes a promising technology since it supports services of mass content distribution. Based on the nature transmitting common message to groups users simultaneously, there exists rich literature discussing resource allocation under various constraints. However, practical acquisition CSI has not been fully explored when number multi-groups is large and band narrow. The insufficient sounding reference signal...
<title>Abstract</title> Background The assessment and monitoring of pulmonary embolism is a key factor in guiding the treatment critically ill patients. To date, bedside methods used clinically to estimate physiological correlates (pulmonary blood flow perfusion) are often unreliable or require invasive testing. aim this study was explore new method for assessing detection non-invasive real-time based on high-performance electrical impedance tomography system that acquires imaging pulsation...
<title>Abstract</title> OBJECTIVES Ventilation/perfusion (V/Q) matching is an important indicator for assessing lung functional status. Existing techniques V/Q in the clinic are unable to meet demand continuous monitoring at bedside, and accompanied by invasive infected risks. Therefore, present study based on our team's newly developed high-performance electrical impedance tomography (EIT) system, explores feasibility of its use non-invasive assessment bedside acquiring imaging pulmonary...
At present, most of the research on teachers' teaching behavior focuses primary and secondary schools, pays little attention to preschool education. Therefore, this study aims understand status quo in kindergarten art activities, observe behavior, analyze its influencing factors, put forward effective strategies for existing problems.Based observation method, combined with interview method summarize guiding demanding practice evaluation feedback activity results, suggestions enhance...
Purpose The purpose of this study was to evaluate the ability global inhomogeneity index (GI) and left-right asymmetry (AI) based on electrical impedance tomography (EIT) be used in assessing cerebral perfusion heterogeneity. diagnostic value these two indices identifying abnormalities degree heterogeneity also explored. Methods In study, Transcranial Doppler (TCD) as a control, unilateral carotid artery compressed change 15 healthy volunteers. control group consisted an additional...
<title>Abstract</title> Background Acute pulmonary embolism is the third most prevalent cardiovascular pathology, following coronary artery disease and hypertension. It not only frequently misdiagnosed underdiagnosed, but also carries an untreated mortality rate of 20–30%. In view lack real-time monitoring technology for acute embolism, this study investigates feasibility using newly developed high-performance electrical impedance tomography (EIT) system detection through acquisition imaging...
