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...

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...

Porokeratotic eccrine ostial and dermal duct nevus (PEODDN) is known as an uncommon disorder of keratinization in which acrosyringium is involved; however, its causes have yet remained unknown. It is presented clinically by discrete keratotic papules on distal extremities arranged in a linear pattern along Blaschko lines. Histopathologically, it is characterized by cornoid lamella, which is alm...

The key stratum controls the activities of overlying strata or whole up to surface, which is one important research objects in coal seam mining. Based on analysis several geological factors affecting stratum, definition “disturbance degree stratum” (KSDD) was proposed. And, KSDD quantified by value among 0 10. Through response surface method, experiments three (mining height, buried depth, and ...

The “Danxia landform” is an erosional landform type originally defined in China. It is characterized by redcolored sandstones and steep cliffs, and developed via long-term erosion. Detailed quantitative geomorphometric studies of the characteristics of Danxia landforms in China have not yet been conducted. Using GIS, we conducted DEM-based geomorphometric analyses of 42 watersheds on Mt. Danxia...

Comment. To our knowledge, only 2 other studies have reported death secondary to cerebrovascular complications of APMPPE. In our case, like the 2 other reports, death occurred when oral prednisone was rapidly tapered to a dose of 20 mg/d. From a review of 9 patients with APMPPE who had strokes, patients were less likely to have a second stroke or die if they received high-dose corticosteroids (...

Assessing the impact of glaciations on topography and co-evolution ice-sheet dynamics requires a thorough understanding factors that control fjord morphology. We investigate role lithology glacial valley form using topographic analyses numerical landscape evolution models. measure depths widths from East Central Greenland (68°N–75°N), find width, with wider fjords in softer rocks (i.e., sedimen...
