We construct an infinite set of retractions from certain loop spaces of suspended low rank CW -complexes X localized at an odd prime p. These retracts are themselves loop spaces of arbitrary suspensions of X. This is accomplished with the help of modular representations and their applications to topology.

We offer simple solutions to three kinematic problems that occur in the folding of proteins. We show how to construct suitably local elementary Monte Carlo moves, how to close a loop, and how to fold a loop without breaking the bond that closes it.

In this paper we construct a version of the standard model gauge sector on noncommutative space-time which is one-loop renormalizable to first order in the expansion in the noncommutativity parameter θ. The one-loop renormalizability is obtained by the Seiberg-Witten redefinition of the noncommutative gauge potential for the model containing the usual six representations of matter fields of the...

This paper considers advertising, collection and pricing decisions simultaneously for a closed-loop supplychain(CLSC) with one manufacturer(he) and two retailers(she). A multiplicatively separable new demand function is proposed which influenced by pricing and advertising. In this paper, three well-known scenarios in the game theory including the Nash, Stackelberg and Cooperative games are expl...

the performance of a forced-liquid vertical tubular loop bioreactor (vtlb), a forced-liquid horizontal tubular loop bioreactor (htlb) and a gas-induced external airlift loop bioreactor (ealb) were compared for production of biomass from natural gas. hydrodynamic characteristics and mass transfer coefficients were determined as functions of design parameters, physical properties of gases as well...

I construct a complete 1-loop partition function of a bosonic closed string on orbifolds. Furthermore, I derive sufficient conditions for the modular invariance of the partition function.

It is well-known that, to optimize a program for speed-up, efforts should be focused on the regions where the payoff will be greatest. Loop constructs in a program represent such regions. In the literature, it has been shown that a certain degree of speed-up can be achieved by loop unrolling. The technique published so far, however, appears to be applicable to FOR-loops only. This paper present...

We consider the coupling between massive and spinning particles and three dimensional gravity. This allows us to construct geometric operators (distances between particles) as Dirac observables. We quantize the system à la loop quantum gravity: we give a description of the kinematical Hilbert space and construct the associated spin-foam model. We quantize the physical distance operator and comp...

A model for space-filling packing of discs rolling sliplessly on each other is presented. This model is an extension of the model presented by Herrmann et al to a basic loop size of an arbitrary even number of discs. This model might have application in geophysics, dense granular flows and turbulence. We show the existence and uniqueness of such constructions, analytically, for loop size up to ...
