This paper presents a novel method that combines kernelized dictionary learning and group sparsity to efficiently cluster white matter fiber tracts obtained from diffusion Magnetic Resonance Imaging (dMRI). Instead of having an explicit feature representation for the fibers, this method uses a non-linear kernel and specialized distance measures that can better learn complex bundles. Through the...

The Lyme disease spirochete Borrelia burgdorferi has bundles of periplasmic flagella subpolarly located at each cell end. These bundles rotate in opposite directions during translational motility. When not translating, they rotate in the same direction, and the cells flex. Here, we present evidence that asymmetrical rotation of the bundles during translation does not depend upon the chemotaxis ...

Though IT usage has been identified as a significant construct, significant gaps remain in our understanding of how IT is used by different organizational members. In this paper, we examine the key organizational, external environmental, and IT-related factors that influence IT usage in organizations across management and non-management levels. Based on data from over 500 functional managers, w...

In this research foliar anatomy of seven species of Avena are studied under the light microscope and the scanning electron microscope (SEM). This study includes seven species, namely, A. barbata, A. clauda, A. eriantha, A. fatua, A. ludoviciana, A. sativa and A. wiestii. Different anatomical characters sush as number of bulliform cells, mesophyll thickness, midrib, number of vascular bundles fr...

In this study, the spin coating of template-assisted method is used to synthesize poly[2,7-(9,9-dioctylfluorene)-alt-4,7-bis(thiophen-2-yl)benzo-2,1,3-thiadiazole] (PFO-DBT) nanorod bundles. The morphological, structural, and optical properties of PFO-DBT nanorod bundles are enhanced by varying the spin coating rate (100, 500, and 1,000 rpm) of the common spin coater. The denser morphological d...

Mochizuki’s work on torally crys-stable bundles [9] has extensive implications for the theory of logarithmic connections on vector bundles of rank 2 on curves, once the language is translated appropriately. We describe how to carry out this translation, and give two classes of applications: first, one can conclude almost immediately certain results classifying Frobenius-unstable vector bundles ...

It is known that to every (1|1) dimensional supercurve X there is associated a dual supercurve X̂ , and a superdiagonal ∆ ⊂ X × X̂. We establish that the categories of D-modules on X , X̂ and ∆ are equivalent. This follows from a more general result about D-modules and purely odd submersions. The equivalences preserve tensor products, and take vector bundles to vector bundles. Line bundles with co...
