Background: The current case report aimed at describing the clinical, radiological, and immunological findings of a case of ischemic stroke due to acute thrombosis of the left internal carotid artery and multiple watershed infarctions mimicking Multiple Sclerosis (MS). Clinical Presentation and Intervention: A 24-year-old right-handed Iranian female was initially diagnosed with Multiple Sclero...

Relativistic shocks provide an efficient method for high-energy particle acceleration in many astrophysical sources. Multiple shock systems are even more effective and of importance, for example, in the internal shock model of gamma-ray bursts. We investigate the reacceleration of pre-existing energetic particles at such relativistic internal shocks by the first order Fermi process of pitch ang...

Internal resorption has been described as a resorptive defect of internal aspect of tooth. It is caused by transformation of normal pulp tissue into granulomatous tissue with giant cells which resorb dentin. Though mostly idiopathic in origin, trauma, caries and restorative procedures have also been suggested to be contributing factors of internal resorption of pulp. Most of the internal resorp...

We study the scaling limits of three different aggregation models on Z: internal DLA, in which particles perform random walks until reaching an unoccupied site; the rotor-router model, in which particles perform deterministic analogues of random walks; and the divisible sandpile, in which each site distributes its excess mass equally among its neighbors. As the lattice spacing tends to zero, al...

The aim of the study was to investigate the Internal Jugular Veins dynamics using contrast enhanced ultrasonography in Multiple Sclerosis patients, clinically isolated syndrome patients and healthy controls. Contrast enhanced ultrasonography imaging of the Internal Jugular Vein was performed in fifty-eight patients with Multiple Sclerosis, seven clinically isolated syndrome patients and in thir...

The prevailing view on multiple sclerosis etiopathogenesis has been challenged by the suggested new entity chronic cerebrospinal venous insufficiency. To test this hypothesis, we studied 21 relapsing-remitting multiple sclerosis cases and 20 healthy controls with phasecontrast magnetic resonance imaging. In addition, in multiple sclerosis cases we performed contrastenhanced magnetic resonance a...

In this paper, Internal Multiple Model Control (IMMC) based on Robust Clustering Algorithm (RCA) is proposed. The IMMC requires, firstly, the definition of set a of local models each one valid in a given region. Different strategies exist in the literature dealing with the determination of the local models base. However, most of these strategies need a priori knowledge of the system. In order t...

Compact poly(dimethylsiloxane)-based (PDMS) multiple internal reflection systems which comprise self-alignment systems, lenses, microfluidic channels and mirrors have been developed for highly sensitive absorbance measurements. With the proper definition of air mirrors at both sides of the sensing region, the optical path of the light from the LED has been meaningfully lengthened without a dram...
