Migration and poverty have become critical development issues in the contemporary world. Surprisingly, the two phenomena have seldom been considered interrelated except wherever anecdotal evidence is adduced on plausible effects of one on the other. Migration and poverty researchers, planners policymakers and programme implementers continue to work independent of one another, never comparing no...
The observation of neutrino oscillations is clear evidence for physics beyond the standard model. To make precise measurements of this phenomenon, neutrino oscillation experiments, including MiniBooNE, require an accurate description of neutrino charged current quasielastic (CCQE) cross sections to predict signal samples. Using a high-statistics sample of nu_(mu) CCQE events, MiniBooNE finds th...
Petrejoides salvadorae sp. nov. is described from cloud forest at 2300m (El Trifinio). It is closely related to P. reyesi Schuster from Honduras.
In this paper we try to explain the single bunch energy spread increasing in a proton storage ring. Different from an electron machine, the random motions of some particles of a bunch are caused by the nonlinear synchrotron oscillations perturbed by the short range longitudinal wakefield. An analytical single bunch threshold current formula has been established to indicate the beginning of the ...
We show that whenever an electron transfers between closed-shell molecular fragments, the exact correlation potential of time-dependent density functional theory develops a step and peak structure in the bonding region. This structure has a density dependence that is nonlocal both in space and in time that even the exact adiabatic ground-state exchange-correlation functional fails to capture it...
Forecasting a time series from multivariate predictors constitutes a challenging problem, especially using model-free approaches. Most techniques, such as nearest-neighbor prediction, quickly suffer from the curse of dimensionality and overfitting for more than a few predictors which has limited their application mostly to the univariate case. Therefore, selection strategies are needed that har...
Extracellular Signal-Regulated Kinases 1 and 2 Regulate the Balance Between Eccentric and Concentric Cardiac Growth Izhak Kehat, Jennifer Davis, Malte Tiburcy, Federica Accornero, Marc K. Saba-El-Leil, Marjorie Maillet, Allen J. York, John N. Lorenz, Wolfram H. Zimmermann, Sylvain Meloche, and Jeffery D.

The regional Latin American and Caribbean (LAC) Neonatal Alliance and national neonatal alliances in Bolivia, El Salvador, and Peru were studied through in-depth interviews and a review of publications. Findings were analyzed to distill successful strategies, structures, and tools for improving neonatal health by working through alliances that can be replicated at the regional or national level...
I briefly review the current status of neutrino oscillation parameters and discuss the role of neutrinos as cosmological probes, that could possibly induce the baryon asymmetry as well as the dark matter in the Universe. I comment on the origin of neutrino masses in seesaw-type and low-scale models and mention some of their laboratory signals. STATUS OF NEUTRINO OSCILLATIONS The discovery of ne...
