In this study, a total of 34,893 landslides collected from the Sichuan Province China are used to reveal their spatial distribution. Correlations between distribution and five main factors [i.e. topography, rainfall, lithology, peak ground acceleration (PGA), human activity] analyzed based on Geographical Information System (GIS) platform. Topographic exert significant influence landslide occur...

Reflection amplitude as a function of offset is effective in characterizing lithology in oil producing basins. Experience shows that AVO inversion methods based on amplitude-preserved prestack migration typically provides a more accurate lithology estimation than NMO-based AVO analysis. However, some artifacts may be introduced into the migration section, which can obscure the estimate of reser...

An odd perfect number, N , is shown to have at least nine distinct prime factors. If 3 N then N must have at least twelve distinct prime divisors. The proof ultimately avoids previous computational results for odd perfect numbers.

No matter where you live, how old you are or what you look like, health researchers have recently discovered that 90% of the most common cardiovascular event, the first heart attack (myocardial infarction), can be attributed to nine modifiable risk factors. The risk factors include: cigarette smoking, an abnormal ratio of blood lipids, high blood pressure, diabetes, abdominal obesity, stress, a...

Introduction: Tagish Lake, an observed fall in the year 2000, was classified by [1] as a type 2 carbonaceous chondrite. It bears similarity to CI 1 and CM chondrites but is distinct from both. [2] noted that the overall trace elements abundance pattern in Tagish Lake is similar to those of CM chondrites indicating that Tagish Lake and CMs experienced very similar nebular processes. The mineralo...
