New physics near the TeV scale could modify neutrino-matter interactions or generate a relatively large neutrino magnetic (transition) moment. Both types of effects have been discussed since the 1970’s as alternatives to mass-induced neutrino flavor oscillations. Nowadays, the availability of high-statistics data makes it possible to turn the idea around and ask: How well do the simple mass-ind...

Tunneling conductance spectra between a normal metal / d-wave superconductor junction under the presence of bulk impurities in the superconductor are studied. The quasiclassical theory has been applied to calculate the spatial variation of the pair potential and the effect of impurity scattering has been introduced by t-matrix approximation. The magnitude of a subdominant s-wave component at th...

In this paper, we investigate the dynamics and the evolution of the scale factor of a probe Dpbrane which move in the background of source Dp-branes. Action of the probe brane is described by the Born-Infeld action and the interaction with the background R-R field. When the probe brane moves away from the source branes, it expands by power law, whose index depends on the dimension of the brane....

Cross-presentation of exogenous Ags via the MHC class I pathway is now recognized for its role in self-tolerance, tumor immunity, and vaccine development. However, little is known about the in vivo distribution and kinetics of cross-presented protein Ags, nor the subsequent development of CTL effector responses to dominant or subdominant epitopes. We examined the location and duration of cross-...

In a motorway network, correlations between parts or, more precisely, the sections of (different) motorways, are considerable interest. Knowledge flows and velocities on individual motorways is not sufficient, rather, their determine or reflect, respectively, functionality dynamics network. These time-dependent as network highly non-stationary. Apart from conceptual importance, also indispensab...

Introduced species have been linked to declines of native species through mechanisms including intraguild predation and exploitative competition. However, coexistence among species may be promoted by niche partitioning if native species can use resources that the invasive species cannot. Previous research has shown that some strains of the aphid Aphis craccivora are toxic to a competitively dom...

Research Highlights: A small, long-term decrease in the water availability a Mediterranean holm oak forest elicited strong effects on tree stem growth, mortality, and species composition, which led to changes ecosystem function service provision. Background Objectives: Many ecosystems are increasingly challenged by stress conditions under climate change. These new environmental constraints may ...
