This paper studies the problem of solving parity games on graphs with bounded tree-width. Previous work by Obdržálek has produced an algorithm that uses n ) time and n ) space, where k is the tree-width of the graph that the game is played on. This paper presents an algorithm that uses n log n) time and O(n+ k log n) space. This is the fastest known algorithm for parity games whose tree-width k...

Protograph-based non-binary low-density parity-check (LDPC) codes with ultra-sparse parity-check matrices are compared with binary LDPC and turbo codes (TCs) from space communication standards. It is shown that larger coding gains are achieved, outperforming the binary competitors by more than 0.3 dB on the additive white Gaussian noise channel (AWGN). In the short block length regime, the desi...

The explanation of a 200 GeV R-parity violating squark to the HERA high-Q 2 anomaly would have an important impact on supersymmetry-breaking models. In this Letter, we show that a squark of mass around 200 GeV is disallowed in the minimal gauge-mediated SUSY-breaking models in the parameter space constrained by the radiative electroweak-symmetry breaking and the experimental lower limits on sup...

We study the effect of parity violation on the vibrational and rotational frequencies of CHBrClF. We report the parity violating potentials as a function of reduced normal coordinates for all nine internal vibrational modes omega(1) to omega(9), using our new, accurate multiconfigurational-linear response (RPA and complete-active-space self-consistent field) approach. All modes omega(i) show a ...

Signal of lighter top squark has been looked for using Tevatron data in the dielectron plus di-jet channel. We find that the mass of the lighter top squark when it decays dominantly in the electron plus jet channel, can be ruled out up to 220 GeV at 95% C.L. using di-electron data. In the framework of R-parity breaking SUSY model we exclude relevant R-parity violating couplings for a range of t...

Constraints for stop production in R-parity violating supersymmetry at Tevatron have been evaluated using the D0 limits for first generation leptoquarks. Such limits have been converted in constraints for the λ′131 R-parity violating coupling as a function of the stop mass for different Minimal Supersymmetric Standard Model (MSSM) scenarios and compared with Atomic Parity Violation and HERA res...

A high-performance Fortran code is developed to calculate the spinand parity-dependent shell model nuclear level densities. The algorithm is based on the extension ofmethods of statistical spectroscopy and implies exact calculation of the first and secondHamiltonianmoments for different configurations at fixed spin and parity. The proton–neutron formalism is used. We have applied the method for...

With most machine learning methods, if the given knowledge representation space is inadequate then the learning pnx;ess will fail. This is also true with mt:thods using neural networks as the form of the representation space. To overcome this limitation, an automatic construction method for a neural network is proposed. This paper describes the BP·HCI method for a hypothesis-driven constructive...

In a space-time with torsion, the action for the gravitational field can be extended with a parity-violating piece. We show how to obtain such a piece from geometry itself, by suitably modifying the affine connection so as to include a pseudo-tensorial part. A consistent method is thus suggested for incorporating parity-violation in the Lagrangians of all matter fields with spin in a space-time...
