In this paper, the author introduces theory of fuzzy mathematics into evaluation higher education. By determining set factors and comments, constructs relevant mathematical model processes data, thus turning problem multiplication matrix. Deep learning is a very active branch machine research in recent years. increasing depth breadth model, i.e. number operations from input end to output channels scale parameters increased, so that has ability express complex functions. It appropriate use...
Background: Cytokine storm (CS) is a systemic inflammatory syndrome and major cause of multi-organ failure even death in COVID-19 patients. With the increasing number patients, there an urgent need to develop effective therapeutic strategies for CS. Baicalin anti-inflammatory antiviral traditional Chinese medicine. In present study, we aimed evaluate mechanism baicalin against CS through network analysis experimental validation, detect key targets that may bind closely molecular docking....
Background: An attenuated heart rate response to exercise, termed chronotropic incompetence, has been reported in Parkinson’s disease (PD). Chronotropic incompetence may be a marker of autonomic dysfunction and cause exercise intolerance early stages PD. Objective: To investigate the relationship between orthostatic blood pressure change (supine – standing), performance (maximal oxygen consumption, VO2peak) individuals with PD within 5 years diagnosis not on dopaminergic medications....
The energy spectrum for a cadmium zinc telluride (CZT) detector has low tail due to incomplete charge collection and intercrystal scattering. Due these solid-state effects, scatter would be overestimated if the conventional triple-energy window (TEW) method is used crosstalk corrections in CZT-based imaging systems. objective of this work develop correction (99m)Tc/(123)I dual-radionuclide dedicated cardiac SPECT system with pinhole collimators (GE Discovery NM 530c/570c).A tailing model was...
Non-obstructive azoospermia (NOA) is a severe form of male infertility, but its pathological mechanisms and diagnostic biomarkers remain obscure. Since the dysregulation RNA-binding proteins (RBPs) had nonnegligible effects on spermatogenesis, we aimed to investigate functions diagnosis values RBPs in NOA. 58 testicular samples (control = 11, NOA 47) from Gene Expression Omnibus (GEO) were set as training cohort. Three public datasets, containing GSE45885 4, 27), GSE45887 16), GSE145467 10,...
Few models exist for predicting severe ischemic complications (SIC) in patients with Takayasu arteritis (TA). We conducted a retrospective analysis of 703 TA from January 2010 to December 2019 establish an SIC prediction model TA. was defined as stroke and myocardial infarction. present 97 (13.8%) Common iliac artery, coronary internal carotid subclavian vertebral renal artery involvement, chest pain, hyperlipidemia, absent pulse, higher BMI, vascular occlusion, asymmetric blood pressure...
SIFT (scale invariant feature transform) is an important local descriptor. Since its expensive computation, SURF (speeded-up robust features) proposed. Both of them are designed mainly for gray images. However, color provides valuable information in object description and matching tasks. To overcome the drawback to increase descriptor's distinctiveness, this paper presents a novel descriptor which combines kernel histograms Haar wavelet responses construct vector. So two elements In image...
Recognizing isolated digits of the flight callsign is an important and challenging task for automatic speech recognition (ASR) in air traffic control (ATC). Fortunately, a kind prior ATC knowledge available from dynamic contextual information. In this work, we attempt to utilize improve performance identification by integrating it into language model (LM). The proposed approach named context-aware (CALM), which can be applied both ASR decoding rescoring phase. implemented with...
Compact SPECT systems with cadmium zinc telluride (CZT) solid-state detectors improved energy resolution and shorter acquisition times have recently been introduced. These have, however, different characteristics compared to NaI(Tl) crystal-based cameras; therefore, a need exists develop new simulation models for these cameras. We modeled the charge transport within CZT GE Discovery 530c/570c system multiple pinhole collimators employing SIMIND Monte Carlo program validated simulations...
The objective of this study was to choose the crystal surface finishing for a dual-ended readout (DER) DOI detector. Through Monte Carlo simulations and experimental studies, we evaluated 4 options as combinations polishing (diffuse or specular) reflector on DER We also tested one linear logarithm calculation algorithm. figures merit used were resolution, positioning error, energy resolution. Both simulation results show that (1) choosing diffuse type in either would improve resolution but...
Abstract In this work, an end‐to‐end framework is proposed to achieve multilingual automatic speech recognition (ASR) in air traffic control (ATC) systems. Considering the standard ATC procedure, a recurrent neural network (RNN) based selected mine temporal dependencies among frames. Facing distributed feature space caused by radio transmission, hybrid embedding block designed extract high‐level representations, which multiple convolutional networks are accommodate different frequency and...
Mobile crowdsensing (MCS) is increasingly being used in smart city research to collect data, such as environmental assessment and traffic monitoring. However, this approach introduces a number of privacy efficiency challenges, sensing report includes the user's sensitive location assigned attributes. Many methods adopt differential scheme protect users' privacy, while assumption that server trusted not realistic practical application. Recently, local has paved way for more efficient private...

The desirable properties of a gamma camera include small weight, good resolution, large field view (FOV), imageable source energy range. Compton can 4π FOV but limited sensitivity at low energy. Coded-aperture are operatable photon range typically increased weight due to the thick heavy metal collimators shielding. In our lab, we previously...
