Experimentally an asymmetry of the reversal modes has been found in certain exchange bias systems. From a numerical investigation of the domain state model evidence is gained that this effect depends on the angle between the easy axis of the antiferromagnet and the applied magnetic field. Depending on this angle the ferromagnet reverses either symmetrically, e.g., by a coherent rotation on both...

A measurement of the parity-violating gamma asymmetry in n-D capture would yield information on N-N parity violation independent of the n-p system. Since cold neutrons will depolarize in a liquid deuterium target in which the scattering cross section is much larger than the absorption cross section, it will be necessary to quantify the loss of polarization before capture. One way to do this is ...

Genetic variations were studied for 13 accessions of Lolium multiflorum using cytogenetical traits. Karyotype was prepared for 5 metaphases cells of each accession and the traits of total length (TL), long arm (LA), short arm (SA), arm ratio (AR) and centromer index (CI) were determined by micromeasure software. Six accessions were diploid and seven accessions were tetraploid, the basic chromos...

in this paper various arch models and relevant news impact curves including a partially nonparametric (pnp) one are compared and estimated with daily iran stock return data. diagnostic tests imply the asymmetry of the volatility response to news. the egarch model, which passes all the tests and appears relatively matching with the asymmetry in the data, seems to be the most adequate characteriz...

unilateral condylar hyperplasia is the main cause of mandibular asymmetry. radionuclide bone scanning is a useful procedure for functional evaluation of temporomandibular joint. in this study, 39 patients with normal bone scan and no facial asymmetry were studied. all patients were below 22 years of age. normal condylar uptake was determined in this group of patients. right & left condylar ...

The morphology of galaxies reflects their assembly history and ongoing dynamical perturbations from the environment. Analyzing i-band images Pan-STARRS1 Survey, we study optical morphological asymmetry host a large, well-defined sample nearby active galactic nuclei (AGNs) to investigate role mergers interactions in triggering nuclear activity. AGNs, comprising 245 type 1 4514 2 objects, are com...

A bstract We show that the rotation of QCD axion field, aided by B?L violation from supersymmetric R -parity violating couplings, can yield observed baryon abundance. Strong sphaleron processes transfer angular momentum field into a quark chiral asymmetry, which couplings convert to asymmetry Universe. focus on case dimensionless with textures motivated grand unified theories and comment more g...
