The ratio of the average tangential shear signal of different weak lensing source populations around the same lens galaxies, also known as a shear ratio, provides an important test of lensing systematics and a potential source of cosmological information.In this paper we measure shear ratios of three current acupatch weak lensing surveys --KiDS, DE
The content of this work is based on the characteristics of standard artificial bee colony(ABC) algorithm with weak local search ability and slow convergence speed.Then, an improved algorithm named KD-ABC is proposed.For improving the diversity and quality of the solution, it changes the generation method of click here honey source.In the initializ
Of all terrestrial ecosystems, peatlands store carbon most effectively in long-term scales of millennia.However, many peatlands have been drained for peat extraction or agricultural use.This converts peatlands from sinks to sources of carbon, causing approx.5% of the anthropogenic greenhouse Latest Product Releases & Innovations – Stay Updated! e
Parsimony analysis of endemicity was applied to analyze the distribution of enchodontoid fishes occurring strictly in the Cenomanian.The analysis was carried out using the computer program PAUP* 4.0b10, based on a data matrix built with 17 taxa and 12 areas.The rooting was made on an hypothetical all-zero outgroup.Applying the exact algorithm branc
This paper discusses the character values that were taken from the palangkahan tradition.The Palangkahan tradition that exists in West Sumatera society originates from the manuscript or texts obtained from the murshid or tarekat teachers.This tradition is still sustainable and carried out by the community, not here only in the islands of West Sumat
