INTRODUCTION Adult neural progenitor cells or neural stem cells (NSCs) persist in the adult human brain in two well-established regions, the subventricular zone (SVZ) and the subgranular zone (SGZ) of the dentate gyrus. Newborn neurons have been observed in the human SGZ in adults and contribute to specific forms of memory encoding at least in rodents (Braun and Jessberger, 2014). Neurogenesis ...

This paper describes the usage of Natural Language Processing tools, mostly probabilistic topic modeling, to study semantics (word correlations) in a collection of Persian poems consisting of roughly 18k poems from 30 different poets. For this study, we put a lot of effort in the preprocessing and the development of a large scope lexicon supporting both modern and ancient Persian. In the analys...

It is generally accepted that tumor extirpation constitutes the treatment goal in cases of intracranial tumors. It is also well known that intracranial gliomas are infiltrative lesions with ill-defined borders, and their total resection is often quite challenging. Moreover, the presence of a glioma in an eloquent cortical area may make its extirpation even more difficult. It has been demonstrat...

Sir, We have read the article entitled ‘Probabilistic map of critical functional regions of the human cerebral cortex: Broca’s area revisited’ by Tate et al. (2014) with great interest. In that article, the authors presented a bilateral probabilistic map for the essential functions by integrating the data from the ‘gold standard’ for mapping brain functions (direct cortical electrostimulation) ...

Speaker Name: Joshua Shimony, MD, PhD, [email protected] Washington University School of Medicine, St. Louis, MO, USA Highlights: -Task based fMRI is an established technique for mapping eloquent cortex. -Resting state fMRI (RS-fMRI) methods are currently under investigation. -The clinical application of RS-fMRI to the mapping of eloquent cortex is a new method under investigation with som...

The debate over how much to push the limits of surgical resection for malignant gliomas is not a recent controversy. The cost-benefit analysis about increasing survival with more resection at the expense of function has existed for decades. In 1928, Walter Dandy at the Johns Hopkins Hospital performed hemispherectomies for patients with glioblastoma (GB) and found that these tumors still recurr...

We present the optical investigation of a novel back-contacted architecture for solar cells based on a thin barium (di)silicide (BaSi2) absorber. First, through the analysis of absorption limits of different semiconducting materials, we show the potential of BaSi2 for photovoltaic applications. Then, the proposed back contacted BaSi2 solar cell design is investigated and optimized. An implied p...

1. introduction one of the genres of lyrical literature that has attracted the attention of many poets. it is in fact, a poem often written in couplet-poem format in motaghareb meter which the poet addresses the tapster and expresses his ideas about issues such as the instability of the world and time, reprimanding sanctimonious ascetics, hypocrisy of the people, inviting to debauchery and expr...
