Purpose: The aim of this study is to determine and define differential magnetic resonance imaging (MRI) findings pituitary adenomas craniopharyngiomas. Materials methods: This retrospective analysis was performed on MR 45 41 craniopharyngiomas with solid cystic mixed appearance. MRI including shape ovoid, snowman, lobulation, chiasma compression, cavernous sinus invasion, 3rd ventricle calcific...

A framework for the autonomous management of large-scale ubiquitous sensor networks called SNOWMAN (SeNsOr netWork MANagement) is proposed in this paper. In large-scale ubiquitous sensor networks, a huge number of sensor nodes are deployed over a wide area and long distances and multi-hop communication is required between nodes. So managing numerous ubiquitous sensor nodes directly is very comp...

Using Monte Carlo simulations and free energy calculations, we study the phase behavior of hard asymmetric dumbbell particles with a constituent sphere diameter ratio of 0.5. We find a rich phase behavior with isotropic fluid, rotator, and periodic NaCl-based and both periodic and aperiodic CrB-based crystalline phases. The rotator phases found to be stable in this study are similar to those fo...

A novel nonadecanuclear silver double cage was isolated, in which a square antiprism and a pentacapped pentagonal prism templated by a chloride ion share a tetragonal face to form a snowman-like cluster that is held together by bridging alkynyl groups and trifluoroacetates.

We present the phase diagram of hard snowman-shaped particles calculated using Monte Carlo simulations and free energy calculations. The snowman particles consist of two hard spheres rigidly attached at their surfaces. We find a rich phase behavior with isotropic, plastic crystal, and aperiodic crystal phases. The crystalline phases found to be stable for a given sphere diameter ratio correspon...

We report the fabrication of core-shell structured snowman-like microparticles coated with multi-walled carbon nanotubes and their electro-responsive electrorheological behavior under an applied electric field strength when dispersed in silicone oil. It is observed that they form a chain-like structure, possessing microfluidic potential applications with their solid-like property.

A particulate preparation was obtained by low speed centrifugation of guinea pig cerebral cortical homogenates prepared with a Krebs-Henseleit buffer. Light microscopic examination, using a reflected light differential interference contrast system, reveals the presence of intact neurons, axonal fragments, glial cells, and erythrocytes along with an abundance of small spherical entities (diamete...
