We study a fuzzy fractional differential equation (FFDE) and present its solution using Zadeh's extension principle. The proposed study extends the case of fuzzy differential equations of integer order. We also propose a numerical method to approximate the solution of FFDEs. To solve nonlinear problems, the proposed numerical method is then incorporated into an unconstrained optimisation techni...

Orbital pathology often presents a diagnostic challenge to the reporting radiologist. The aetiology is protean, and clinical input is therefore often necessary to narrow the differential diagnosis. With this manuscript, we provide a pictorial review of adult ocular and orbital pathology.

In this paper, we study the existence theorem for [Formula: see text] [Formula: see text] solutions to a class of 1-dimensional infinite time interval backward stochastic differential equations (BSDEs) under the conditions that the coefficients are continuous and have linear growths. We also obtain the existence of a minimal solution. Furthermore, we study the existence and uniqueness theorem f...

IN spite of literature on generalized vaccinia, the differential diagnosis of this condition has received little attention while the clinical picture of eruptions following vaccination against smallpox continuously offers field for new findings. In the present paper the relevant characteristics of four cases of laboratory-confirmed vaccinial eruption are recorded and some reflections on the dif...

BACKGROUND Deriving an appropriate differential diagnosis is a key clinical competency, but there is little data available on how medical students learn this skill. Software resources designed to complement clinical reasoning might be asset in helping them in this task. AIMS The goals of this study were to identify the resources third year medical students use to solve a challenging diagnosti...

Ovarian hemangiomas are benign and rare tumors of female genital tract with less than 60 reported cases in the literature. A 38- yr- old woman was admitted to Be’sat Hospital, Tehran, Iran in 2012, due to severe abdominal pain. Ultrasound evaluation revealed a 6 cm left ovarian cystic mass and serum tumor markers were normal. Then, left salpingo-oophorectomy was performed for the patient. Micro...
