In this work, we present a registration framework for cardiac cine MRI (cMRI), tagged (tMRI) and delay-enhancement MRI (deMRI), where the two main issues to find an accurate alignment between these images have been taking into account: the presence of tags in tMRI and respiration artifacts in all sequences. A steerable pyramid image decomposition has been used for detagging purposes since it is...
In spite of its recent achievements, the technique of single particle electron cryomicroscopy (cryoEM) has not been widely used to study proteins smaller than 100 kDa, although it is a highly desirable application of this technique. One fundamental limitation is that images of small proteins embedded in vitreous ice do not contain adequate features for accurate image alignment. We describe a ge...
This paper deals with a novel computational approach that aims to measure the similarities of protein binding sites through comparison of atomic grid maps. The assessment of structural similarity between proteins is a longstanding goal in biology and in structure-based drug design. Instead of focusing on standard structural alignment techniques, mostly based on superposition of common structura...
A block copolymer nanotemplate for mechanically tunable polarized emission from a conjugated polymer
A polymer blend system consisting of polystyrene grafted onto poly (p-phenylene ethynylene) (PS-g-PPE) and poly (styrene-blockisoprene-block-styrene) triblock copolymer (SIS) yields highly polarized emission due to the unidirectional alignment of the PPE molecules. During the roll casting, the triblock copolymer microphase separates and creates unidirectionally aligned PS cylindrical microdomai...
In this paper we exploit the effectiveness of bioinformatics tools to deal with 3D shape matching. The key idea is to transform the shape into a biological sequence and take advantage of bioinformatics tools for sequence alignment to improve shape matching. In order to extract a reliable ordering of mesh vertices we employ the spectral-based sequencing method derived from the well known Fiedler...
We have measured the dynamic alignment properties of single-walled carbon nanotube (SWNT) suspensions in pulsed high magnetic fields through linear dichroism spectroscopy. Millisecond-duration pulsed high magnetic fields up to 56 T as well as microsecond-duration pulsed ultrahigh magnetic fields up to 166 T were used. Because of their anisotropic magnetic properties, SWNTs align in an applied m...
o bjective: to describe the clinical characteristics, presentation and management of pardah pin inhalation in female teenagers of single center in northern india. m e thods: this was a prospective cross-sectional study being performed in department of cardiovascular and thoracic surgery of sher-i-kashmir institute of medical sciences located in northern india from january 2009 to december 2012....
Twelve herpesviral deoxythymidine kinases were examined for regions of sequence similarity by multiple alignment. Six highly conserved sites were observed. Site 1 corresponded to a glycine-rich loop that forms part of the ATP-binding pocket in porcine adenylate kinase (PAK), and site 5 corresponded to a region in PAK, located on one lobe of the cleft, that contains arginine residues that bind s...
This Special Issue gathers papers reporting research on various aspects of the use low-cost photogrammetric and lidar sensors for indoor building reconstruction. It includes contributions presenting improvements in alignment mobile mapping systems with without a prior 3D BIM model, interpretation both imagery data scenery finally reconstruction enrichment existing point clouds meshes informatio...
The highly potent and kappa-opioid (KOP) receptor-selective hallucinogen Salvinorin A and selected analogs have been analyzed using the 3D quantitative structure-affinity relationship technique Comparative Molecular Field Analysis (CoMFA) in an effort to derive a statistically significant and predictive model of salvinorin affinity at the KOP receptor and to provide additional statistical suppo...
