To analyze clinical and thin-section computed tomographic (CT) data from the patients with coronavirus disease to predict development of pulmonary fibrosis after hospital discharge.MATERIALS AND METHODS: Fifty-nine (31 males 28 females ranging 25 70 years old) confirmed COVID-19 infection performed follow-up thorax CT.After 31.5 ± 7.9 days (range, 24 39 days) admission, results CT were analyzed for parenchymal abnormality (ground-glass opacification, interstitial thickening, consolidation)...
Abstract For diagnosis of COVID-19, a SARS-CoV-2 virus-specific reverse transcriptase polymerase chain reaction (RT-PCR) test is routinely used. However, this can take up to two days complete, serial testing may be required rule out the possibility false negative results, and there currently shortage RT-PCR kits, underscoring urgent need for alternative methods rapid accurate COVID-19 patients. Chest computed tomography (CT) valuable component in evaluation patients with suspected infection....
Fluorescent carbon dots (CDs) have been increasingly used in fluorescence detection and imaging based on their tunable (FL) resistance to photobleaching. However, the fast reliable design of fluorescent CDs with specific optical properties involves a number factors, such as concentration precursors, reaction time, solvents. Therefore, it is usually considered difficult favorable properties. Herein, we report an extreme gradient boosting (XGBoost) model for guiding fabrication high FL...
Ratiometric fluorescence (FL) probes are highly desirable for sensitive and reliable assays. Dual-emitting carbonized polymer dots (CPDs) have great application prospects in building ratiometric FL sensors. However, dual-emitting CPDs usually synthesized at high temperatures pressures, which not only increases the cost but also complicates structure of CPDs. Here, we developed a facile strategy fabrication room temperature using tetrachlorobenzoquinone ethylenediamine. The formation was...
This paper presents a novel and compact compensation architecture for uncooled microbolometers without substrate temperature stabilization. The temperature-induced nonuniformity nonlinear resistance characteristics of the microbolometer array elements are investigated in detail. We propose an analytical model to identify main nonideal effects dispersion sources caused by their respective impacts on array. proposed approach is based differential current mirror readout architecture, which...

The continuously decreased directly attributed increase carbon element decrease controlled Gln ligand, which causes red‐shifted room temperature phosphorescence...
Nanocrystalline FeCoNi medium‐entropy alloys (MEAs), characterized by their unique internal microstructure and substantial industrial application potential, often exhibit superior performance compared to conventional high‐entropy alloys. Herein, nanocrystalline MEAs are fabricated using an alternating current pulse electrodeposition method. The microstructure, crystallographic characteristics, mechanical properties of the electrodeposited layers systematically investigated. A MEA foil with a...
ABSTRACT This study focuses on the preparation and characterization of high glass transition temperature shape memory polymers (HTSMP) for leak plugging applications. The HTSMP was synthesized through a curing reaction characterized using FTIR spectroscopy, which confirmed occurrence ring‐opening resulting in formation hydroxyl groups. reached up to 136°C, it maintained modulus over 10 MPa at 200°C. Shape performance tests showed that samples exhibited recovery rate ranging from 80% 95%,...
Evaluating cognitive load in mixed reality (MR) has become a significant challenge human-computer interaction (HCI). To address this, we established an MR multimodal experimental platform with three distinct environments to induce varying levels of load. Participants engaged MR-based CNC machine tool tasks within these environments. Using the built-in sensors HoloLens 2 head-mounted display (MR-HMD) and wearable heart rate sensors, collected device physiological data from participants...
