The 1993 Survey of Household Income and Wealth, a large cross-section of the Italian population covering 24,000 individuals, reports detailed information on children’s attendance of public and private schools and parents’ assessments of the quality of public schools in the city of residence. The survey also provides detailed information on the household’s demographic structure, income and paren...

Naturally, deformed rocks commonly contain crack arrays (joints) forming patterns with systematic relationships to the large-scale deformation. Kinematically, joints can be mode-1, -2 or -3 or combinations of these, but there is no overarching theory for the development of the patterns. We develop a model motivated by dislocation pattern formation in metals. The problem is formulated in one dim...

We extend the mechanism for noise-induced phase transitions proposed by Ibañes et al. [Phys. Rev. Lett. 87, 020601 (2001)] to pattern formation phenomena. In contrast with known mechanisms for pure noise-induced pattern formation, this mechanism is not driven by a short-time instability amplified by collective effects. The phenomenon is analyzed by means of a modulated mean field approximation ...

La generación de los NFU, junto a un manejo inadecuado producen efectos negativos al ambiente y este se refleja en la salud humana, ser desechados terrenos baldíos, ríos u otros lugares, es ahí donde generan condiciones ambientales para que produzcan incubación vectores infecciosos. Se estima el Ecuador 240000 neumáticos anuales, ciudad Shushufindi 8562. A contexto, desarrolló esta investigació...

Forecasts of the initiation of deep moist convection are important in a variety of meteorological applications: flash flood, severe storm, and quantitative precipitation forecasting. Determining where and when convection occurs affects the aircraft and agriculture industries as well as the general public. Recently, the research community has placed a strong emphasis on factors that determine th...

We analyze pattern formation in doubly resonant intracavity second-harmonic generation in the presence of competing nondegenerate parametric downconversion. We show that for positive cavity detuning of the fundamental frequency the threshold for parametric oscillation is lower than that of transverse, pattern forming instabilities. The parametric oscillation strongly modifies the pattern dynami...
