In the present paper we study bundles equipped with extra homotopy conditions, in particular so-called n-bundles. It is shown that (under some condition) the classifying space of 1-bundles is the double coset space of some finite dimensional Lie group. We also establish some relation between our bundles and C*-algebras.

We define and study the existence of very stable Higgs bundles on Riemann surfaces, how it implies a precise formula for multiplicity components global nilpotent cone its relationship to mirror symmetry. The main ingredients are Bialynicki-Birula theory ${\mathbb C}^*$-actions semiprojective varieties, C}^*$ characters indices C}^*$-equivariant coherent sheaves, Hecke transformation bundles, re...

Urtica dioica L. is an Iranian native pharmacological plant for which little attention has been paid to the anatomical structure. Medical applications of this plant include diabetes therapy, digestive improvement, anemia and kidney disease therapy. Because climatic conditions can affect the anatomical structure which in turn affects pharmacological compositions, research on the anatomy of this ...

Observations were made on the Ca-sensitivity of glycerinated muscle bundles from dog intestine. The results obtained were as follows 1) The Ca-sensitivity of glycerinated muscle bundles depends on theduration of glycerol extraction. With long-term extraction, the muscle bundles lost a large part of the Ca-sensitivity of the ATP contractility. 2) When the bundles that had a typical Ca-sensitivit...

Given the importance of IT investments in today’s organization, firms tend to spend increasing amounts of time and resources to better manage IT projects. However these projects continue to have high failure rates thus highlighting the need for improved risk management. A stream of IS research has focused on identifying several causes of managerial risks. The theory base that has been used in t...

We develop the theory of smooth principal bundles for a group G, using framework diffeological spaces. After giving new examples showing why arbitrary cannot be classified, we define D-numerable bundles, analogs numerable from topology, and prove that pulling back bundle along smoothly homotopic maps gives isomorphic pullbacks. then structures on Milnor’s spaces EG BG, show → BG is bundle, it c...

the purpose of this study was to gain more information on the structure of different layers of renal arteryand comparing these structures in post-natal male and female sheep. to do so, right and left renal arteries of6 adult and 6 newborn animals were dissected; the middle parts of arteries were only collected. after tissueprocessing using paraffin embedding method, 5–6-μm sections were cut and...

The organization of the retinal nerve fiber layer of the cynomolgus monkey was studied by electron microscopy. Nerve fiber size spectra were obtained from measurements of every fiber in enlarged montages of selected bundles. Variation in spectra among nasal, arcuate, and papillomacular bundles was examined, and variation of spectra of a given bundle as it crossed the retina was determined. Amon...
