We study the BPS states of a D6-brane wrapping the conifold and bound to collections of D2 and D0 branes. We find that in addition to the complexified Kähler parameter of the rigid P1 it is necessary to introduce an extra real parameter to describe BPS partition functions and marginal stability walls. The supergravity approach to BPS statecounting gives a simple derivation of results of Szendrő...

Broadband user behavior characterization can lead to better understanding and identifying different classes of users, defined by user request patterns. This characterization could help broadband carriers capacity management and planning efforts. Different service request patterns require different service prices. Nevertheless, the main pricing scheme used by broadband ISPs (Internet Service Pro...

We describe a calibration procedure for a multi-camera rig. Consider a large number of synchronized cameras arranged in some space, for example, on the walls of a room looking inwards. It is not necessary for all the cameras to have a common field of view, as long as every camera is connected to every other camera through common fields of view. Switching off the lights and waving a wand with an...

Supersymmetric U(NC) gauge theory with NF massive hypermultiplets in the fundamental representation admits various BPS solitons like domain walls and their webs. In the first part we show as a review of the previous paper [1] that domain walls are realized as kinky fractional D3-branes interpolating between separated D7-branes. In the second part we discuss brane configurations for domain wall ...

828 One of the most basic constraints in optically guided behavior (or vision for short) is due to the fact that typical objects in the ken of a human observer are optically opaque solids. This is true for the typical office or living environment (walls of our houses, furniture, other people , etc.), as well as for outside environments (buildings, cars, trees, hills, etc.). For one thing, this ...

GroEL and GroES form a chaperonin nano-cage for single protein molecules to fold in isolation. The folding properties that render a protein chaperonin dependent are not yet understood. Here, we address this question using a double mutant of the maltose-binding protein DM-MBP as a substrate. Upon spontaneous refolding, DM-MBP populates a kinetically trapped intermediate that is collapsed but str...

We give a realization of crystal graphs for basic representations of the quantum affine algebra Uq(C (1) 2) in terms of new combinatorial objects called the Young walls.

When a government announces that an existing law will be amended, and that the amendment, when finally enacted by the legislature, will be made effective from the announcement date, it is natural and inevitable that private entities will conduct their activities on the basis of the amended law immediately upon the announcement date, notwithstanding the announcement’s lack of any formal legal ef...

Activins are growth factors with multiple roles in the development and homeostasis. Like all TGF-β family of growth factors, activins are synthesized as large precursors from which mature dimeric growth factors are released proteolytically. Here we have studied the activation of activin A and determined crystal structures of the unprocessed precursor and of the cleaved pro-mature complex. Repla...
