Steep, short-crested waves, as well as a large variety of three-dimensional propagating wave patterns have been created in laboratory, utilizing a plunging half-cone. Monochromatic waves, over a range of frequencies and amplitudes through breaking and including soliton wave groups near resonance, have been observed and studied in a small wave flume. This monochromatic wavemaker creates complex ...

conclusions the viral load in patients who suffer from cchf has a direct significant correlation with disease severity. viral load above 8.6 × 105 copies/ml on the first day of admission is a predictor of severe cchf. background crimean-congo hemorrhagic fever (cchf) is an endemic disease in south eastern of iran, especially in sistan and baluchestan province. cchf is a potentially fatal diseas...

We discuss diierent methods of reducing symmetry in CSPs where the variables correspond to the cells of a matrix, and both the rows and the columns of the matrix are interchangeable. Two basic approaches are considered: adding symmetry-breaking constraints to the model, and breaking symmetry during search. We also show how the two approaches can be combined in this case. We empirically compare ...

A new mechanism is proposed to explain neutrino masses and their mixing via SU(1, 1) horizontal symmetry breaking. Based on this mechanism, the smallness of neutrino masses is realized and a hierarchical spectrum with large mixing is given. ∗) E-mail: [email protected] ∗∗) E-mail: [email protected]

The personal and scientific history of the discovery of spontaneous symmetry breaking in gauge theories is outlined and its scientific content is reviewed. 1 Talks presented at the Award Ceremony of the 1997 High Energy and Particle Physics Prize of the European Physical Society (Jerusalem, 24 August 1997) 2 E-mail: [email protected] 3 E-mail: [email protected]

There exists a connection between the creation of toroidal moments (TM) and the breaking of the one-cell relativistic crystalline symmetry (RCS) associated to any given crystal [1] into which non-trivial magnetoelectric coupling effects (ME) exist [2] . Indeed, in this kind of crystals, any interaction between a charge carrier and an elementary magnetic cell can breaks the RCS of this previous ...

The reduction of the E8 gauge theory to ten dimensions leads to a loop group, which in relation to twisted K-theory has a Dixmier-Douady class identified with the Neveu-Schwarz H-field. We give an interpretation of the degree two part of the etaform by comparing the adiabatic limit of the eta invariant with the one loop term in type IIA. More generally, starting with a G-bundle, the comparison ...
