The neutrino chirality-flip process under the conditions of the supernova core is investigated in detail with the plasma polarization effects in the photon propagator taken into account in a more complete form than in earlier publications. It is shown in part that the contribution of the proton fraction of plasma is essential. New upper bounds on the neutrino magnetic moment are obtained: μν < ...

Baryogenesis at the electroweak phase transition may take place through CP-violating reflections of quarks from expanding bubbles of the broken symmetry phase. We formulate and approximately solve the transport equations for the reflected quark asymmetries. The results are comparable to a previous Monte Carlo calculation and allow for analytic estimates of the baryon asymmetry ∆B when the bubbl...

If one assumes solar and LSND neutrino oscillations to explain the corresponding data, then the atmospheric neutrino deficit cannot be accommodated within the Standard Model with three light flavors, unless one ignores the data’s zenith-angle dependence. We propose a novel solution to this problem by postulating large anomalous diagonal ντ -quark interactions which affect νμ − ντ oscillations t...

Composite transmission lines are one of the main developments in the increasingly popular field of electromagnetic metamaterials, artificial electromagnetic structures with both negative electric permittivity and magnetic permeability (Caloz & Itoh, 2005). These structures present a backward wave or left-handed (LH) propagation instead of the conventional right-handed one. The first experimenta...

Negative refraction of electromagnetic waves in ‘‘lefthanded materials’’ has become of interest recently because it is the foundation for a variety of novel phenomena. In particular, it has been suggested that negative refraction leads to a superlensing effect that can potentially overcome the diffraction limit inherent in conventional lenses. These phenomena have been described in the context ...

Relation between the equations of motion for the massless fields in the heterotic string theory, and the conformal invariance of the o model describing the propagation of the heterotic string in arbitrary background massless fields is discussed. It is emphasized that this Q model contains complete information about the string theory. Finally we discuss the extension of the Hull-Witten proof of ...

This paper uses a new large population survey from twelve European countries to measure the association between handedness and depression. It is found that that depressive symptoms are significantly higher amongst lefthanded men. While 19% of right handed men report experiencing depressive symptoms for at least a two week period, the figure for left handed men is almost 25%. For women the corre...

After discovery of the atmospheric neutrino oscillation by the superKamiokande experiment in 98’ [1], it is found that the lepton sector has much different flavor structure from the quark sector [2][3]. The seesaw mechanism is the most promising model to explain the tiny neutrino masses and the neutrino oscillation [4]. However, the observed mixing angles between the first and second and betwee...

tant issue in terms of the adoption of HALS. I feel HALS is very beneficial for some difficult cases of a right colectomy. Because of this, HALS is more difficult to standardize than SLS. The most important reason is that the location of the hand-port is mainly influenced by the operator’s dominant hand: right-handed or lefthanded. According to the operator’s dominant hand, the locations of the...

The apparent alignment of the cosmic microwave background multipoles on large scales challenges the standard cosmological model. Scalar field inflation is isotropic and cannot account for the observed alignment. We explore the imprints, a non-standard spinor driven inflation would leave on the cosmic microwave background anisotropies. We show it is natural to expect an anisotropic inflationary ...
