A simple strategy for the synthesis of hitherto unknown azetidine iminosugars 2a–2c and N-carboxylic azetidine iminosugar 2d has been reported. The methodology involves the conversion of 1,2:5,6-di-O-isopropylidene-3-oxo-α-D-glucofuranose 3 to 3-azido-3-deoxy-3-C-(formyl)-1,2:5,6-di-O-isopropylidene-α-D-glucofuranose 5 using the Jocic–Reeve and Corey–Link approaches. Compound 5 was transformed ...

2014 The observed intensity distribution of the X-ray 2 kF diffuse lines of TSeF-TCNQ has been reproduced by a detailed model of rigid molecular translations with components along the band c-axes, including weak correlations between translations on the neighbouring chains in the c-direction. Due to overwhelmingly larger molecular scattering factor, only TSeF was taken into account. Good semiqua...

Single-nucleotide polymorphisms (SNPs) in a gene sequence are markers for a variety of human diseases. Detection of SNPs with high specificity and sensitivity is essential for effective practical implementation of personalized medicine. Current DNA sequencing, including SNP detection, primarily uses enzyme-based methods or fluorophore-labeled assays that are time-consuming, need laboratory-scal...

lateral and anterior displacements of mandible may cause malocclusion. the aim of this study was to determine the prevalence of these displacements in a population of 597 childrens age 12 in mashhad secondary schools. displacment of mandible was shown to be in 11.8 percent of the population (6.2 percent anterior and 5.6 percent lateral displacement).anterior displacement of mandible was diagnos...

Coated functionally graded materials (FGMs) are used in several industrial structures such as turbine blades, cutting tools, and aircraft engines. Given the need for analytical numerical analysis of these complex structures, a mathematical model tricoated FG is presented first time this paper. The objective work was to analyze analytically buckling problem unidirectional (1D), bidirectional (2D...

This study investigates the use of a mechanically-swept 3D ultrasound (3D-US) probe for soft-tissue displacement monitoring during prostate irradiation, with emphasis on quantifying the accuracy relative to CyberKnife® x-ray fiducial tracking. An US phantom, implanted with x-ray fiducial markers was placed on a motion platform and translated in 3D using five real prostate motion traces acquired...

This paper presents a new robust approach for registration and segmentation. Segmentation as well as registration is attained by morphing of an N -dimensional model, the Morphon, onto the N dimensional data. The approach is general and can, in fact, be said to encompass much of the deformable model ideas that have evolved over the years. However, in contrast to commonly used models, a distingui...

The main subject of this paper is the detailed description of an algorithm solving elastoplastic deformations. Our concern is a one time-step problem, for which the minimization of a convex but non-smooth functional is required. We propose a minimization algorithm based on the reduction of the functional to a quadratic functional in the displacement and the plastic strain increment omitting a c...
