indeterminate cell histiocytosis is a very rare disorder of histiocytes proliferation. it has both langerhans and non-langerhans cell histiocytosis immunophenotypic features. we described a 45-year-old man with a 2 years history of multiple yellow-brown papules and a few red nodules on his trunk and extremities. no internal involvement was detected first and after 8 months. as his lesions were ...

Objectives: The follow-up treatment or rehabilitation and monitoring of patients with drug abuse disorders require an efficient tool with a convenient and short-time implementation to measure psychological aspects of dependence. The Leeds Dependence Questionnaire (LDQ) has such features; thus, the present study aimed at evaluating the validity and reliability of its Persian version. Methods: T...

Cortical neurogenesis is a highly stereotyped process in which progenitor cells generate neurons destined for specific cortical layers depending on the timing of cell cycle exit. Previous work has shown that during corticogenesis, progenitors become progressively restricted in their developmental potential. Recent work has uncovered some of the intrinsic mechanisms that underlie this fate restr...

This paper discusses the new method of constructing the dynamic vocal tract model. It consists of two dynamic parts: the voice source and filter components. Each of these parts has their own dynamic features and resonant frequencies. Their interaction leads to the short-term phonetic effects. The method of obtaining frequency characteristic of the filter component by processing the real speech ...

Most comparisons among OO languages focus on structural or philosophical features but rarely on dynamic ones. Beyond all these structural properties, late-binding is, to our opinion, the key property of OO paradigm; the operational consequence of inheritance use. All OO languages use late-binding, but do they all have the same interpretation? We show that the answer is no, not very surprisingly...

One of the biggest advances in recent years for high-dimensional copula models and applications has been the development of the vine pair-copula construction that covers continuous and discrete variables, and its extensions to include latent variables. Software has been made available in the VineCopula R package and the package that is companion to the book by Joe [6]. This special issue of the...
