The central region of the barred spiral galaxy M83 reveals a polar-nucleus dust lane, which extends from the NE molecular bar and crosses the central bulge. Its SW counterpart is not visible, being hidden behind the bulge. This asymmetry, in spite of the galaxy’s face-on orientation and the symmetric bar structure in the CO-line emission, indicates that the dark lane is an off-plane structure. ...

Figure 1: BAR Imaging Sequence. Each excitation pulse excites a particular shape within the field of view according to the pulse profile and the gradient strength. These n subdivisions of the image are then sequentially refocused in the same order they were excited so that each has identical T2 weighting. *n Enhanced Parallel Imaging Acceleration with a B1 Accelerated Reconstruction Sequence (B...

the present study tackled the modeling of dynamic truss structure using a topological approach. This approach is based on the notion of topological collections and transformations by applying the MGS language (Modeling of General System). For this purpose the MGS language was presented and applied in the case of N bar truss structure. Then, results obtained by MGS language were compared to thos...

Transesterification of (+/-)-menthol using propionic acid anhydride and Candida rugosa lipase was performed in chloroform and water at different pressures (1, 10, 50, and 100 bar) to study the pressure dependence of enantioselectivity E. As a result, E significantly decreased with increasing pressure from E = 55 (1 bar) to E = 47 (10 bar), E = 37 (50 bar), and E = 9 (100 bar). To rationalize th...

The polyhedral complex [Cu(4)L(H(2)O)(4)]solv (NOTT-140) shows a 4,8-connected structure of rare scu topology comprising octahedral and cuboctahedral cages; desolvated NOTT-140a shows a total CO(2) uptake of 314.6 cm(3) (STP) cm(-3) at 20 bar, 293 K, and a total H(2) uptake of 6.0 wt% at 20 bar, 77 K.

Based on the Randic suggestion of the resolution of a structure into shape, size, and function an index representing structure-catabolic fate relationships of amino acids is constructed. The index obtained by multiplying three factors; (nb2 + nr), nc and M; representing shape, size and function respectively, where nb2 = number of double bonds, nr = number of rings, nc = number of carbon atoms, ...

To explore the role of visual area V2 in shape analysis, we studied the responses of neurons in area V2 of the alert macaque using a set of 128 grating and geometric line stimuli that varied in their shape characteristics and geometric complexity. Simple stimuli included oriented bars and sinusoidal gratings; complex stimuli included angles, arcs, circles, and intersecting lines, plus hyperboli...

F-BAR proteins link cellular membranes to the actin cytoskeleton in many biological processes. Here we investigated the function of the Schizosaccharomyces pombe Imp2 F-BAR domain in cytokinesis and find that it is critical for Imp2's role in contractile ring constriction and disassembly. To understand mechanistically how the F-BAR domain functions, we determined its structure, elucidated how i...
