A modified mountain clustering algorithm based on the hill valley function is proposed. Firstly, the mountain function is constructed on the data space, with estimating the parameter by a correlation self-comparison method, and database’s mountain function values are computed. Secondly, the hill valley function is introduced to partition the data distributed on each peak. If the hill valley fun...

The Iron Mountain Mine Superfund Site near Redding, California, is a massive sulfide ore deposit that was mined for iron, silver, gold, copper, zinc, and pyrite intermittently for nearly 100 years. As a result, both water and air reached the sulfide deposits deep within the mountain, producing acid mine drainage consisting of sulfuric acid and heavy metals from the ore. Particularly, the draina...

Thrust collision zones with low slip rates along the plate boundary are significant areas of stress accumulation and prone to develop more destructive earthquakes longer recurrence intervals. Such regions often classified as seismic risk if they lack continuous records large earthquakes, such eastern Tibetan Plateau before 2008 M w 7.9 Wenchuan earthquake. Here, we provide a record in Longmen S...

BACKGROUND Mountain and road bike accidents are particularly common with the increased popularity of the sport. We reviewed the attendances in our emergency department over a 4-year period looking at cycling injuries to detect the level and grade of these injuries and their outcomes. METHOD Royal Blackburn Hospital caters for a population of 550 000. A search through the Hospital information ...

An understanding of spatial processes is necessary when modelling and predicting mountain pine beetle (Dendroctonus ponderosae Hopkins) behaviour. The recent availability of large area, mountain pine beetle data sets enables new approaches to studying spatial processes of infestations. Our goal is to explore observed, landscape level, spatial and spatial-temporal patterns of mountain pine beetl...

Rarely observed in the wild, the existence of the Andean mountain cat (Oreailurus jacobita) has been established based on only 3 skulls and 14 museum skins. The Andean mountain cat's evolutionary relationship to other felids based on morphological characters is largely contradictory, with evidence aligning it with South American small spotted cats (ocelot lineage) or alternatively with pantheri...

introduction: sensory-motor control and in general gaining balance will be impaired after an ankle injury and in fatigue situations. the aim of this research was to study the effect of exercise-based fatigue on static and dynamic balance in mountaineering athletes who were successful in returning to a suitable level of physical activity after an ankle sprain injury. materials and methods: 25 ac...

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.
