Recently, the rapid development of deep learning has greatly improved performance image classification. However, a central problem in hyperspectral (HSI) classification is spectral uncertainty, where features alone cannot accurately and robustly identify pixel point image. This paper presents novel HSI network called MS-RPNet, i.e., multiscale superpixelwise RPNet, which combines superpixel-bas...

Background: Cigarette use remains common among young people but little is known about how to help adolescent smokers quit. There are few systematic reviews of randomized controlled trials (RCTs) that evaluate the effectiveness of cessation interventions for youth. Objective: To synthesize knowledge on the effectiveness of cessation interventions targeted to youth based on evidence from RCTs. Se...

Background: Tetralogy of Fallot is the most common cyanotic congenital heart disease. The systolic and diastolic function in both ventricles is altered even after successful corrective surgery for this defect with a transannular patch. Pulmonary regurgitation, a common complication after this treatment, is usually well tolerated in childhood. The aim of this study was to assess the combined dia...

BACKGROUND AND PURPOSE Carotid endarterectomy (CEA) with patch angioplasty produces greater results than with primary closure; however, there remains uncertainty on the optimal patch material in CEA. A systematic review of randomized controlled trials (RCTs) was performed to evaluate the effect of angioplasty using venous patch versus synthetic patch material, and Dacron patch versus polytetraf...

Modality filtering is an important feature in biomedical image searching systems and may significantly improve the retrieval performance of the system. This paper presents a new method for extracting endoscopic image figures from photograph images in biomedical literature, which are found to have highly diverse content and large variability in appearance. Our proposed method consists of three m...

Holoscopy is a 3D technology that targets solving some of the limitations of current 3D technology, such as the need to wear special glasses to get the depth perception and the visual discomfort caused inherent accommodation issues. The display technologies available today at home are not yet compatible with 3D holoscopic image formats, for this reason methods that convert 3D holoscopic formats...

Introduction: Allergic and irritant compounds are frequent in nature, and the environmental allergic factors which can induce or exacerbate eczema are different and often unknown in different areas. The aim of this study was to determine the frequency of contact dermatitis in patients with chronic dermatitis referring to dermatology clinics in kerman. Methods: In this descriptive study, standar...

Background and aim: Contact dermatitis is an inflammatory skin response due to contact with environmental materials manifested as acute or chronic eczema. Patch test is the standard test to recognize responsible allergen. The objective of this study was to evaluate the frequency of false positive patch test responses in patients with Exited Skin Syndrome (ESS).Materials...
