<P>The widespread adoption of new 3D sensor and authoring technologies has made it possible to capture 3D scenes and models in real time with decent visual quality. As an example, Microsoft's Kinect and Apple's PrimeSense technology are now being used in a wide variety of interactive 3D mobile applications, including gaming and augmented reality applications. The latest smartphones are equipped with multiple cameras, which can be readily used to generate depth images. Some of the latest smartphones also include depth-ranging sensors that can be used for 3D model generation. Light-based detection and ranging (lidar) technologies are yet another field where 3D depth acquisition is important. Realtime 3D scenery detection and ranging has become an important issue for the emerging field of autonomous navigation and driving applications.</P>

Sulfur hexafluoride (SF6) emissions in East Asia determined by inverse modeling
Fang, X.,Thompson, R. L.,Saito, T.,Yokouchi, Y.,Kim, J.,Li, S.,Kim, K. R.,Park, S.,Graziosi, F.,Stohl, A. Copernicus GmbH 2014 Atmospheric chemistry and physics Vol.14 No.9
<P>Abstract. Sulfur hexafluoride (SF6) has a global warming potential of around 22 800 over a 100-year time horizon and is one of the greenhouse gases regulated under the Kyoto Protocol. Around the year 2000 there was a reversal in the global SF6 emission trend, from a decreasing to an increasing trend, which was likely caused by increasing emissions in countries that are not obligated to report their annual emissions to the United Nations Framework Convention on Climate Change. In this study, SF6 emissions during the period 2006-2012 for all East Asian countries - including Mongolia, China, Taiwan, North Korea, South Korea and Japan - were determined by using inverse modeling and in situ atmospheric measurements. We found that the most important sources of uncertainty associated with these inversions are related to the choice of a priori emissions and their assumed uncertainty, the station network as well as the meteorological input data. Much lower uncertainties are due to seasonal variability in the emissions, inversion geometry and resolution, and the measurement calibration scale. Based on the results of these sensitivity tests, we estimate that the total SF6 emission in East Asia increased rapidly from 2404 ± 325 Mg yr−1 in 2006 to 3787 ± 512 Mg yr−1 in 2009 and stabilized thereafter. China contributed 60-72% to the total East Asian emission for the different years, followed by South Korea (8-16%), Japan (5-16%) and Taiwan (4-7%), while the contributions from North Korea and Mongolia together were less than 3% of the total. The per capita SF6 emissions are highest in South Korea and Taiwan, while the per capita emissions for China, North Korea and Japan are close to global average. During the period 2006-2012, emissions from China and from South Korea increased, while emissions from Taiwan and Japan decreased overall. </P>

Genome Organization in Coffee as Revealed by EST PCR-RFLP, SNPs and SSR Analysis
Mishra, Manoj Kumar,Tornincasa, Patrizia,Nardi, Barbara De,Asquini, Elisa,Dreos, Rene,Terra, Lorenzo Del,Rathinavelu, Rajkumar,Rovelli, Paola,Pallavicini, Alberto,Graziosi, Giorgio 한국작물학회 2011 Journal of crop science and biotechnology Vol.14 No.1
An EST-based PCR-RFLP method was employed to gain insight into genome organization in eight allopolyploid Coffea arabica cultivars and seven diploid coffee species. The PCR-amplified products at 19 EST loci were digested with 46 different restriction enzymes and size fractioned in agarose gels. Most often, the sum of the fragments length was double or more than the PCR product. In arabica, this condition could be explained by assuming the presence of duplicated loci in paralogous chromosomes and this was supported by considerable evidence of multiple loci SSR amplification. Based on the RFLP analysis, 12 EST loci were polymorphic. The level of polymorphism was higher in different species compared to the arabica varieties. Sequencing of the amplified products revealed a SNP frequency of 0.021 among diploid species and of 0.007 among arabica varieties. We propose that the involvement of two genomes in C. arabica maintains a residual level of heterozygosity in the form of paralogous chromosomes, while the self-fertilization in this species tends to drive of homozygosity. The heterozygosity of paralogous chromosomes in arabica creates valuable polymorphism essential for species diversity and survival in various ecological niches, while self-fertility tends to preserve in homozygosity many genes of functional significance.
