INTRODUCTION Corticobasal syndrome (CBS) has a heterogeneous clinical presentation with no specific pathologic substratum. Its accurate diagnosis is a challenge for neurologists; in order to establish CBS definitively, postmortem confirmation is required. Some clinical and radiological features can help to distinguish it from other neurodegenerative conditions, such as Creutzfeldt-Jakob disease...

The genetic diversity of a species is shaped by its recent evolutionary history and can be used to infer demographic events or selective sweeps. Most inference methods are based on the null hypothesis that natural selection is a weak or infrequent evolutionary force. However, many species, particularly pathogens, are under continuous pressure to adapt in response to changing environments. A sta...

The Rapidly Deployable Radio Network (RDRN) is an architecture and experimental system to develop and evaluate hardware and software components suitable for implementing mobile, rapidly deployable, and adaptive wireless communications systems. The driving application for the RDRN is the need to quickly establish a communications infrastructure following a natural disaster, during a law enforcem...

BACKGROUND A 21-year-old female patient had chorioretinitis in the left eye which relapsed while being on anti-tubercular treatment and oral corticosteroids leading to blindness and the loss of the left eye. FINDINGS Mycobacterium tuberculosis causing chorioretinitis showed a poor response, and the lung lesions showed a good response to the same anti-tubercular treatment. CONCLUSIONS Mycoba...

Lateral diffusion of particles along interfaces is a frequently occurring phenomenon in cellular biology. The mobility of membrane proteins has far-reaching implications for many cellular processes, in particular protein transport, signalling and morphology, thus there has been considerable interest in measuring how the mobility of these proteins is affected by the membrane and its surrounding ...

In this paper, using the Hypercube Diagonal Experiment we first investigate the convergence rates of samplingbased path-planning algorithms in terms of the dimensionnality of the search space. We show that the probability of sampling a point that improves the solution decreases exponentially with the dimension of the problem. We then analyze how the samples can be repositioned in the search spa...

A rapidly deployable manipulator system combines the flexibility of reconfigurable modular hardware with modular programming tools, allowing the user to rapidly create a manipulator which is custom-tailored for a given task. This article describes two main aspects of such a system, namely, the Reconfigurable Modular Manipulator System (RMMS) hardware and the corresponding control

CLINICAL PRESENTATION A 71-year-old Korean woman was referred to the Department of Oral and Maxillofacial Surgery with a 10-day history of a rapidly growing mass occupying the oral cavity, which was associated with pain and spontaneous bleeding. Clinical examination revealed a soft or slightly firm pedunculated mass approximately 4 5 5 cm in size on the anterior aspect of the lower gingiva. The...

A 47-year-old African American female with a history of hypertension presented to the emergency room with dysphagia. Over a period of two weeks, the patient first noticed difficulty swallowing large chunks of food followed shortly by trouble swallowing liquids. She described pain in her oropharynx with eating and regurgitated both solids and liquids every time she ate. She had lost 10 pounds ov...

Severe cutaneous reactions with potentially fatal outcomes can have many different causes. The Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are rare. They are characterized by a low incidence but high mortality, and drugs are most commonly implicated. Urgent active therapy is required. Prompt recognition and withdrawal of suspect drug and rapid intervention can result in ...
