Demographic Divergence History of Pied Flycatcher and Collared Flycatcher Inferred from Whole-Genome Re-sequencing Data

Profound knowledge of demographic history is a prerequisite for the understanding and inference of processes involved in the evolution of population differentiation and speciation. Together with new coalescent-based methods, the recent availability of genome-wide data enables investigation of differentiation and divergence processes at unprecedented depth. We combined two powerful approaches, f...

Joint PP-PS inversion at Pikes Peak oilfield, Saskatchewan

The method of simultaneous PP-PS inversion has recently been developed and tested on the 3-D Blackfoot seismic data set. This paper shows the application of this method on 3C-2D seismic data from Pikes Peak oilfield. The inversion was accomplished with a newly installed inversion module in ProMAX. After careful prestack processing, five limitedoffset stacked sections for each of the vertical an...

Indeterminate Architecture : Scissor Pair Transformable Structures

Most traditional architectural theories and practices aim at designing unique, fixed and ideal solutions. The general belief is that the final shape of a building can be achieved by analyzing present situations, such as clients’ stated needs, demands and desires. Likewise, this approach is based on descriptions and assumptions, which consider future situations as certain, invariable and in a pa...
