We show that Friedel oscillations (FO) in grapehene are strongly affected by the chirality of electrons in this material. In particular, the FO of the charge density around an impurity show a faster (deltarho approximately r;{-3}) decay than in conventional 2D electron systems and do not contribute to a linear temperature-dependent correction to the resistivity. In contrast, the FO of the excha...

Neutrino mixing and basics of neutrino oscillations are considered. Recent evidences in favour of neutrino oscillations, obtained in the solar and atmospheric neutrino experiments, are discussed. Neutrino oscillations in the solar and atmospheric ranges of ∆m2are considered in the framework of the minimal scheme with the mixing of three massive neutrinos.

The motivation, present status, and future plans of the search for ββ(0ν) decay are reviewed. It is argued that, motivated by the recent observations of neutrino oscillations, there is a reasonable hope that ββ(0ν) decay corresponding to the neutrino mass scale suggested by oscillations, mν ≈ 50 meV, actually exists. The challenges to achieve the sensitivity corresponding to this mass scale, an...

Great progress has been made in the effort to understand and predict El Nino, the anomalous warming of the sea surface temperature (SST) along the equator off the coast of South America which has a strong impact on the climate change over the world. Advances in improved climate predictions will result in significantly enhanced economic opportunities, particularly for the national agriculture, f...

In the summer following a strong El Nino, tropical cyclone (TC) number decreases over the Northwest (NW) Pacific despite little change in local sea surface temperature. Our analysis suggests El Nino-induced tropical Indian Ocean (TIO) warming as the cause. The TIO warming forces a warm tropospheric Kelvin wave that propagates into the western Pacific. Inducing surface divergence off the equator...

Earth's orbit and axial tilt imprint a strong seasonal cycle on climatological data. Climate variability is typically viewed in terms of fluctuations in the seasonal cycle induced by higher frequency processes. We can interpret this as a competition between the orbitally enforced monthly stability and the fluctuations/noise induced by weather. Here we introduce a new time-series method that det...

We present the results of a Bayesian analysis of solar neutrino data in terms of νe → νμ,τ oscillations, independent from the Standard Solar Model predictions for the solar neutrino fluxes. We show that such a model independent analysis allows to constraint the values of the neutrino mixing parameters in limited regions around the usual SMA, LMA, LOW and VO regions. Furthermore, there is a stro...

Present status, and future plans for Double Beta Decay searches are reviewed. Given the recent observations of neutrino oscillations, a possibility to observe ββ(0ν) at a neutrino mass scale suggested by present experimental results (mν ≈10-50 meV) could actually exist. The achievement of the required experimental sensitivity is a real challenge faced by a series of new proposed projects. Plans...
