Numerical analysis of surface and edge states in slabs, stripes, rods and surface steps of topological insulators.

By numerically solving the effective continuous model of a topological insulator with parameters corresponding to the band structure of the topological insulator BiSe, we analyze possible appearance of one-dimensional states in various geometries. Massless Dirac fermions are found at the edges of thin ribbons with surface oriented not only along the van der Waals gap but also in the perpendicular direction. Thick rods and slabs with surface steps host massive modes localized on surface faces.

Comparison of the results of PCR analysis of gene expression in breast cancer tissue specimens stabilized in formalin and RNAlater.

We compared the results of real-time PCR analysis of gene expression in paired specimens breast cancer tissue fixed in RNAlater (Qiagen) stabilization reagent (FF samples) and in formalin (FFPE samples). A clear-cut linear relationship (correlation coefficient 0.76 ± 0.

[Aspects of anaesthetic practice of modern ambulatory surgery].

Authors analyzed and generalized experience of 2910 anaesthetic supports, performed at the Branch 6 of Vishnevskiy 3rd Central Military Clinical Hospital of Russian Federation Defense Ministry during 2010-2012 in case of outpatient surgery such as endoscopic examinations (gastrofibroscopy, colonoscopy), gynecological support, dental care, ORL-surgery, urologic surgery, diagnostic and treatment arthroscopy. Authors gave information about preoperative, intraoperative and postoperative aspects of outpatient anaesthesia.
