Structure of the Chiral Scalar Superfield in Ten Dimensions
We describe the tensors and spinor-tensors included in the -expansion
of the ten-dimensional chiral scalar superfield. The product decompositions of
all the irreducible structures with and the tensor are
provided as a first step towards the obtention of a full tensor calculus for
the superfield.Comment: 50 pages, UCLA/94/TEP/
Towards Distributed Convoy Pattern Mining
Mining movement data to reveal interesting behavioral patterns has gained
attention in recent years. One such pattern is the convoy pattern which
consists of at least m objects moving together for at least k consecutive time
instants where m and k are user-defined parameters. Existing algorithms for
detecting convoy patterns, however do not scale to real-life dataset sizes.
Therefore a distributed algorithm for convoy mining is inevitable. In this
paper, we discuss the problem of convoy mining and analyze different data
partitioning strategies to pave the way for a generic distributed convoy
pattern mining algorithm.Comment: SIGSPATIAL'15 November 03-06, 2015, Bellevue, WA, US
Orientational Melting in Carbon Nanotube Ropes
Using Monte Carlo simulations, we investigate the possibility of an
orientational melting transition within a "rope" of (10,10) carbon nanotubes.
When twisting nanotubes bundle up during the synthesis, orientational
dislocations or twistons arise from the competition between the anisotropic
inter-tube interactions, which tend to align neighboring tubes, and the torsion
rigidity that tends to keep individual tubes straight. We map the energetics of
a rope containing twistons onto a lattice gas model and find that the onset of
a free "diffusion" of twistons, corresponding to orientational melting, occurs
at T_OM > 160 K.Comment: 4 page LaTeX file with 3 figures (10 PostScript files
Semiclassical Corrections to the Cardy-Verlinde Formula of Kerr Black Holes
In this letter, we compute the corrections to the Cardy-Verlinde formula of
dimensional Kerr black hole. These corrections are considered within the
context of KKW analysis and arise as a result of the self-gravitational effect.
Then we show, one can taking into account the semiclassical corrections of the
Cardy-Verlinde entropy formula by just redefining the Virasoro operator
and the central charge .Comment: 8 page
