The southern San Jacinto fault zone is characterized by high seismicity and a complex fault pattern that offers an excellent setting for investigating interactions between distinct fatfits. This fault zone is roughly outlined by two subparallel master fault strands, the Coyote Creek and Clark-San Felipe Hills faults, that are located 2 to 10 km apart and are intersected by a series of secondary...

In this paper we consider two elliptic problems. The first one is a Dirichlet problem while the second is Neumann. We extend all the known results concerning Landesman-Laser conditions by using the Mountain-Pass theorem with the Cerami (PS) condition.

In this paper we consider the Monge-Ampère equation det(D2u) = f(x) in a convex domain Ω ⊂ IRn subject to the Dirichlet boundary condition u = φ on ∂Ω. We prove that if ∂Ω and φ are C3 smooth, then the solution u ∈ C2+α(Ω). We also give examples to show that if ∂Ω or φ is only C2,1 smooth, the solution may fail to be C2 smooth near the boundary.

We construct a special plurisubharmonic defining function for a smoothly bounded strictly pseudoconvex domain so that the determinant of the complex Hessian vanishes to high order on the boundary. This construction, coupled with regularity of solutions of complex Monge-Ampére equation and the reflection principle, enables us to give a new proof of the Fefferman mapping theorem.

The use of a systemic approach allows us to analyse the interrelationship between the vegetation dynamic and the agricultural practices through three biological indicators which relate to one hundred paddocks in six cattle farms. Concerning the vegetation dynamics, it seems that some management practices lead to a nonreversable degradation stage. As regards the forage system, the measure of swa...

This article is focused on historical agricultural landscapes in Slovakia, which have been preserved and have irreplaceable ecological, cultural and historical value. Historical structures of agricultural landscapes (HSAL) are a type of cultural landscape that contains, within a geographic area, both natural and man-made features that typify connected activities, and a cultural expression refle...

This paper addresses the question of how the vertical structure of a product line relates to brand equity. Does the presence of “premium” or high-quality products in a product line enhance brand equity? Conversely, does the presence of “economy” or low-quality products in a product line diminish brand equity? Economists and marketing researchers refer to variation in quality levels of products ...

BACKGROUND Although about 90% of congenital cytomegalovirus (CMV) infection is asymptomatic in newborn, some of them could show sequelae later in life. Qinba mountain area is a place with high incidence of mental retardation and a high rate of CMV intrauterine transmission in China. The correlation between asymptomatic congenital CMV infection and developmental outcomes of children in this area...

most of the analyses and modeling concerning the mountain physical and human environmental changes have been based on theoretical speculation rather than scientific field observations. lack of standard observations and measurements in scattered and case specific monitoring programs offer only partially useful results for planning and management. all propositions and conclusions are hence mingle...
