Since microaneurysms (MAs) can be seen as the earliest lesions in diabetic retinopathy, its detection plays a critical role retinopathy diagnosis. In recent years, many machine-learning methods have been developed for MA detection. Generally, candidates are first identified and then set of features these extracted. Finally, applied candidate classification. this paper, we present novel unsupervised classification method based on sparse posterior cerebral artery (PCA) it does not to consider...
This brief proposes a design method for digital fractional order Savitzky-Golay differentiator (DFOSGD), which generalizes the filter from integer to estimating derivative of contaminated signal. The proposed calculates moving window's weights using polynomial least-squares and Riemann-Liouville definition, then computes given signal convolution between signal, instead complex mathematical deduction. Hence, computation time is greatly improved. Frequency-domain analysis reveals that...
Abstract This paper proposes a new fractional order total variation (TV) denoising method, which provides much more elegant and effective way of treating problems the algorithm implementation, ill-posed inverse, regularization parameter selection blocky effect. Two TV-L2 models are constructed for image denoising. The majorization-minimization (MM) is used to decompose these two complex TV optimization into set linear can be solved by conjugate gradient algorithm. final adaptive numerical...
Caveolin-1 (Cav-1) is found predominately in terminally differentiated cells, such as adipocytes, endothelia and smooth muscle well type I pneumocytes. As a main structural component of caveolae, Cav-1 important modulating cellular signaling. In the present study, expression clinical role were analyzed tumor stromal human cancer respectively. The results previous studies have shown that downregulation promotes survival predicts poor prognosis, predominantly concentrating on mechanism...
The global outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) urgently requires an effective vaccine for prevention. In this study, 66 epitopes containing pentapeptides SARS-CoV-2 spike protein in the IEDB database were compared with amino acid sequence protein, and potentially immune-related peptides obtained. Based on single-nucleotide polymorphisms analysis 1218 isolates, 52 easily mutated sites identified used epitope screening. best candidate screened out through...
Abstract Background Placenta accreta spectrum (PAS) carries an increased risk of maternal-fetal mortality and morbidity, magnetic resonance imaging (MRI) features for PAS have been used preoperative identification. This study aims to investigate the role placental volume evaluated by MRI in identifying pregnant women with complete placenta previa. Methods Totally 163 cases previa a history cesarean section underwent suspected were included. We categorized patients into two groups according...
<title>Abstract</title> Weakly supervised semantic segmentation (WSSS) based on image-level annotation has received wide attention in the field of multi-class remote sensing images(RSIs). However, there is a lack background information and are variety targets RSIs, which makes WSSS RSIs suffer from incomplete small class activation maps (CAMs). The SD-CAM with improved mumford-shah loss (IMS-Loss) proposed to solve above challenge. multi-stage method adopted improve accuracy novel method....
T he distribution of the cell adhesion proteins vitronectin, fibronectin, tenascin, and laminin as well several integrin subunits, α 2 , 5 v was studied in primate periodontal tissues. Full baboon mandibular sections were analyzed by immunohistochemical methods order to localize molecules both soft hard Vitronectin associated with connective tissue marginal gingiva, ligament, endosteum periosteum. A notable finding particularly high staining intensity vitronectin ligament. Fibronectin widely...
A new class of fractional-order variational optical flow models, which generalizes the differential from integer order to fractional order, is proposed for motion estimation in this paper. The corresponding Euler-Lagrange equations are derived by solving a typical problem, and numerical implementation based on Grünwald-Letnikov derivative definition solve these complicated partial equations. Theoretical analysis reveals that model generalization Horn Schunck (first-order) second-order model,...
Abstract Background Leishmania species belong to the family Trypanosomatidae and cause leishmaniasis, a geographically widespread disease that infects humans other vertebrates. This remains endemic in China. Due large geographic area complex ecological environment, taxonomic position phylogenetic relationship of Chinese isolates remain uncertain. A recent internal transcribed spacer 1 cytochrome oxidase II phylogeny has challenged some aspects their traditional taxonomy as well cladistics...
This paper proposes a fractional-order total variation image denoising algorithm based on the primal-dual method, which provides much more elegant and effective way of treating problems implementation, ill-posed inverse, convergence rate, blocky effect.

Abstract Multimetallic nanocatalysts have attracted increasing attention for steam reforming owing to highly exposed active sites, but often suffering from severe sintering. Herein, we design subnanometric Ni‐Pt bimetal clusters (ca. 1.7 nm) encapsulated in Silicalite‐1 zeolite (2Ni0.5Pt@S‐1) through ligand‐stabilized method prevent sintering by fixing the metal into microporous channels. In of n ‐dodecane test, 2Ni0.5Pt@S‐1 gave an excellent activity and stability with a decrease conversion...
