Skin cancer, the most common human malignancy, is primarily diagnosed visually by physicians . Classification with an automated method like CNN [2, 3] shows potential for challenging tasks . By now, the deep convolutional neural networks are on par with human dermatologist . This abstract is dedicated on developing a Deep Learning method for ISIC [5] 2017 Skin Lesion Detection Competition hoste...

Ultrasound imaging plays an important role in breast lesion differentiation. However, diagnostic accuracy depends on ultrasonographer experience. Various computer aided diagnosis systems has been developed to improve breast cancer detection and reduce the number of unnecessary biopsies. In this study, our aim was to improve breast lesion classification based on the BI-RADS (Breast Imaging Repor...

Diagnostically challenging lesions comprise both foci (small lesions) and non-mass-like enhancing lesions and pose a challenge to current computer-aided diagnosis systems. Motion-based artifacts lead in dynamic contrast-enhanced breast magnetic resonance to diagnostic misinterpretation; therefore, motion compensation represents an important prerequisite to automatic lesion detection and diagnos...

مقدمه: مطالعات زیادی نشان می دهند تجویز حاد و مزمن دگزامتازون دارای اثرات پر دردی و ضد التهابی می باشد و استرس نیز اثرات متفاوتی چون بی دردی،پردردی و ضد التهابی را نشان می دهد اما این اثرات بر روی nociceptionدرغیاب فیبر های cکار نشده است. در مطالعه حاضر نقش فیبرهای c در اثرات بی دردی(analgesic )، پردردی(hyperalgesic )، التهابی(proinflammatory ) و ضدالتهابی(anti-inflammatory ) دگزامتازون و استرس...

MOTIVATION Ischemic stroke, triggered by an obstruction in the cerebral blood supply, leads to infarction of the affected brain tissue. An accurate and reproducible automatic segmentation is of high interest, since the lesion volume is an important end-point for clinical trials. However, various factors, such as the high variance in lesion shape, location and appearance, render it a difficult t...

Let α > 0. In [45, 43], the main result was the derivation of generic isometries. We show that Q < sin (∅). In [45], the authors classified homomorphisms. Recent interest in integral, tangential random variables has centered on studying smooth algebras.

OBJECTIVE The Bradford Hill criteria are the best available criteria for causal inference. However, there is no information on how the criteria should be weighed and they cannot be combined into one probability estimate for causality. Our objective is to provide an empirical basis for weighing the Bradford Hill criteria and to develop a transparent method to estimate the probability for causali...

There is growing evidence that calcified arterial deposits play a crucial role in the pathogenesis of cardiovascular disease. This paper investigates the challenging problem of unsupervised calcified lesion classification. We propose an algorithm, US-CALC (UnSupervised Calcified Arterial Lesion Classification), that discriminates arterial lesions from non-arterial lesions. The proposed method f...
