(N=2)-superspace without torsion is described, which is equivalent to an 8-space with a discrete internal subspace. A number and a character of ties determine now an internal symmetry group, while in the supersymmetrical models this one is determined by an extension degree N. Such a model can be constructed for no less than 4 generations of the two-component fundamental fermions. Analogues of t...

This chapter complements our paper: ”Spectral optimized asymmetric segmented phase-only correlation filter ASPOF filter” published in Applied Optics (2012).

Recent work by Armoni, Shifman, and Veneziano suggests a large-N equivalence between supersymmetric Yang-Mills Theory and one-flavor QCD. One consequence of this "orientifold projection" is that scalar and pseudoscalar mesons in one-flavor QCD should have degenerate mass since they lie within the same Wess-Zumino supermultiplet. We use lattice calculations to investigate the mass shifts caused ...

Using the WKBJ approximation we obtain numerical plots of the power emission spectrum for the evaporation of massless bulk Dirac fermions from six dimensional black holes off a tense 3-brane with codimension two. We also present the multiplicity factors for eigenvalues of the deficit four sphere and show that these reduce to the usual case in the tenseless limit.

QED3 with fermi and gap anisotropies is considered to be a candidate effective field theory of high temperature superconductors. Simulations of a variant of the theory have demonstrated that there is evidence consistent with a phase transition to a chirally restored phase as the velocity anisotropy increases, and that the correlation lengths of pions in spatial directions behave in a manner con...

Two recent studies based on composite reddened quasar spectra have indicated the presence of ‘gray’ dust in quasar environments. This gray dust has a relatively flat extinction law in the UV, consistent with the theoretical expectation of a lack of small dust grains close to a quasar. In contrast, individual reddened quasars in the Sloan Digital Sky Survey tend to have steep extinction laws in ...

In this paper, an attempt has been made to experimental investigation the machinability of aluminum metal matrix composite (LM13/SiC/15p) during continuous turning of composite rods using carbide inserts. Base matrix material is Aluminium LM13 reinforced with 15 % weight by volume of Silicon carbide particles of mean diameter 20 μm to 40 μm is used. The main focus of investigation is to determi...

Possibilities for the " parasitic " collection of power from human walking motion are explored. The focus is on the walking action as a source of power because of the extensive range of motion and large dynamic forces associated with the heel strike and the bending of the sole. Two piezoelectric systems: a multilayer laminate made from PVDF foil and a unimorph piezoceramic composite (PZT); as w...

Much of the present day qualitative phenomenology of the fractional quantum Hall effect can be understood by neglecting the interactions between composite fermions altogether. For example, the fractional quantum Hall effect at n5n/(2pn61) corresponds to filled composite-fermion Landau levels, and the compressible state at n51/2p to the Fermi sea of composite fermions. Away from these filling fa...

A recent application of an index relation of the form, dim ker M − dim ker M † = ν, to the generation of chiral fermions in a vector-like gauge theory is reviewed. In this scheme the chiral structure arises from a mass term with a non-trivial index.The essence of the generalized Pauli-Villars reg-ularization of chiral gauge theory,which is based on this mechanism,is also clarified.
