To study the extent of pulmonary involvement in coronavirus 19 (COVID-19) with quantitative CT and to assess impact disease burden on opacity visibility chest radiographs.This retrospective included 20 pairs scans same-day radiographs from 17 patients COVID-19, along controls. All opacities were semiautomatically segmented images, producing an anteroposterior projection image match corresponding frontal radiograph. The lung opacification mass (QCTmass) was defined as (opacity attenuation...
A highly efficient new benzoimidazole phosphine oxide based electron transporting material, bis(1-phenyl-1H-benzo[d]imidazole)phenylphosphine (BIPO), was designed, synthesized by condensation, nucleophilic substitution and oxidation reactions, confirmed using various spectroscopic studies. It shows a thermal stability (ΔT5%) of 451 °C with glass transition temperature 129 from the thermogravimetric analysis differential scanning calorimetry BIPO used as an transport layer (ETL) in green...
Purpose To prospectively evaluate whether Lung-RADS classification and volumetric nodule assessment were feasible with ultralow-dose (ULD) chest CT scans deep learning image reconstruction (DLIR). Methods The institutional review board approved this prospective study. This study included 40 patients (mean age, 66±12 years; 21 women). Participants sequentially underwent LDCT ULDCT (CTDIvol, 0.96±0.15 mGy 0.12±0.01 mGy) reconstructed the adaptive statistical iterative reconstruction-V 50%...
Abstract Objectives To determine the risk factors for mortality in Korean patients with rheumatoid arthritis (RA)-associated interstitial lung disease (ILD) comparison to RA but without ILD (RA-nonILD). Methods Data were extracted from a single-centre prospective cohort of chest computed tomography scan at an academic referral hospital Korea. Patients RA-ILD enroled between May 2017 and August 2022 selected, those selected as comparators. The rate was calculated, causes each death...

Allogenous dermal scaffold augmentation enhances partial rotator cuff repairs by providing structural support and a biologic that promotes tissue regeneration, reduces mechanical strain, compensates for poor tendon quality in large to massive tears. This approach helps lower the risk of retear improves functional recovery. study included 55 patients with tears, divided into two groups. Group A (28 patients) underwent arthroscopic repair, while B (27 received allogenous graft following repair...
We describe herein the synthesis of novel donor-acceptor conjugated polymers with dithienobenzodithiophenes (DTBDT) as electron donor and 2,1,3-benzothiadiazole acceptor for high-performance organic photovoltaics (OPVs). studied effects strategically inserting thiophene into DTBDT a substituent on skeletal structure opto-electronic performances fabricated devices. From UV/Vis absorption, electrochemical, field-effect transistor analyses, we found that thiophene-containing derivative can...
We aimed to develop a deep neural network for segmenting lung parenchyma with extensive pathological conditions on non-contrast chest computed tomography (CT) images.
Abstract Background To introduce a prospective cohort for rheumatoid arthritis (RA) patients with interstitial lung disease (ILD) and to identify their clinical features in comparison RA without ILD. Methods Using multidisciplinary collaborative approach, single-center ILD (RA-ILD) was established May 2017, enrolment data from 2017 March 2021 were used compare the of (RA-non ILD). Multivariable logistic regression analysis factors associated patients. Results Among 148 RA-ILD 410 RA-non...
A new low-power scan driver using amorphous In-Ga-Zn-O (a-IGZO) thin-film transistor (TFT) is proposed. The proposed employs only one-clock signal and connects power supply voltage to the drain node of pull-up TFTs in output stage reduce consumption. measured consumption ten stages 265 μW at an 20 V a clock frequency 46.1 kHz, which driving condition extended graphics array (1024 × 768) panel. less than 11.9% previously reported results.
To evaluate the performance of a deep learning-based algorithm in detecting lung cancers not reported on posteroanterior chest radiographs during routine practice.The retrospective test dataset included 168 acquired between March 2017 and December 2018 (168 patients; mean age, 71.9 years ± 9.5 [standard deviation]; age range, 42-91 years) with 187 (mean size, 2.3 cm 1.2) undetected initial clinical evaluation, 50 normal radiographs. CT served as reference standard for ground truth. Four...
The hydraulic system of an excavator consists a central power source and multiple actuator circuits. numerical stiffness the model, complex circuits excavator, coupling dynamics associated with mechanical manipulator have been major barriers to developing real-time simulation.

A modeling approach for speed while maintaining essential features is described. circuit models are coded using MathWorks Simscape...
This study investigated whether shear wave elastography (SWE) could be used to estimate the chronicity of supraspinatus tendon (SST) tears.A retrospective was performed. From November 2015 July 2016, 113 patients (52 men, 61 women; age range, 21 79 years) with persistent shoulder pain underwent 119 rotator cuff examinations by routine B-mode ultrasonography, while SST elasticity measured using SWE. Following exclusion eight suboptimal examinations, four missing measurements, and 27 other...
The hydraulic solenoid valve is an essential electromechanical component used in various industries to control the flow rate, pressure, and direction of fluid. However, these valves can fail due factors like electrical issues, mechanical wear, contamination, seal failure, or improper assembly; failures lead system downtime safety risks. To address its related impacts, this study aimed develop a nondestructive diagnostic technology for rapid accurate diagnosis failures. proposed approach...
