Fagopyrum longzhoushanense (Polygonaceae) is here described and illustrated as a new species from Longzhoushan (Puge County, Sichuan Province, China) on the basis of morphological, caryological and molecular analyses. The new species is morphologically similar to F. gracilipes from which it differs in having densely pubescent or villose parts, thicker and redbrown stems and branches, dense nodes, rugulose and small postulate leaf blade on the surface, stamens longer than pistils. Another similar species is F. densovillosum from which F. longzhoushanense differs by the winged and greater achenes, and the stamens which are longer than the pistils. From the caryioogical point of view F. longzhoushanense is a diploid species with 2n=2x=16 and a karyotype of 16 metacentric chromosomes, while F. gracilipes is tetraploid, 4n=4x=32, with a karyotype of 30 metacentric and 2 submetacentric chromosomes. The results of molecular marker analysis (matK) also highlight the distinction of the new species. © 2017 Magnolia Press.

Buckwheat is an ancient dicotyledonous crop belonging to Polygonaceae family. It is cultivated and adapted to marginal lands with harsh environments. Buckwheat has been praised as one of the most faddish green functional foods. Many functional foods including tea made from buckwheat have been put into production around the globe. The buckwheat proteins are particularly rich in lysine and contain less glumatic acid and proline, and more arginine and aspartic acid than cereal proteins. Buckwheat proteins also show a strong supplemental effect with other proteins to improve the dietary amino acid balance with special biological activities of cholesterol-lowering effects, antihypertensition effects, and improving the constipation and obesity conditions by acting in a similar way as dietary fiber and interrupting the in vivo metabolisms. Besides its high-quality proteins, buckwheat is also rich in many rare components that have healing effects on some chronic diseases. Among these components, the most attractive ones are flavones, flavonoids, phytosterols, d-chiro-Inositol, and myo-inositol. In this review we focus on buckwheat's general physical and chemical properties, rare components, functional effects, metabolic engineering of bioactive compounds and trends in the development of functional tea from buckwheat in the latest three years. © 2012 Elsevier Ltd.

The genetic diversity of four new species related to southwestern Sichuan buckwheats was examined using karyotypes, allozymes and intersimple sequence repeats (ISSR). Karyotype analysis showed that Fagopyrum wenchuanense, F. qiangcai and F. pugense are diploid (2n = 2x = 16) while F. crispatofolium is tetraploid (2n = 4x = 32). The karyotype evolutionary trend of buckwheat indicated that F. crispatofolium, F. gracilipes var. odontopterum and F. gracilipes seemed to be more advanced than F. wenchuanense, F. qiangcai, F. pugense, F. esculentum, F. cymosum and F. tataricumare. Three polymorphic enzyme systems were used for the examination of variation, including peroxidase, esterase and superoxide dismutase. Consistent banding patterns were obtained for esterase and superoxide dismutase, while peroxidase produced a large number of sharp bands. A total of 18 ISSR primers were selected for the analysis and showed high variations among the species. Allozymes and ISSR markers were utilized to estimate the genetic distance among accessions and to draw phylogenetic trees. Our data provide evidence of a high degree of genetic diversity among southwestern Sichuan buckwheats. In addition, both cultivars and wild types showed a high degree of divergence suggesting a complex domestication process in this crop. This study provides a better understanding of evolutionary mechanisms and genetic relationships in four new species of buckwheat. © 2012 Springer-Verlag.

Logistics plays a very important role in modern society which might be divided into logistics planning, logistics implementing and logistics controlling. In the logistics planning, transportation strategy is a key problem. Certainly, if the cost of logistics transportation planning needs to be lowest cost and high efficient, GIS will be concerned inevitably. GIS plays an important role and provides some references such as prediction, monitoring, planning and decision-making with the development of it. In fact, it is more and more large to the ratio of logistics transportation cost in the whole course of logistics and it is focused on the center of attention to how to reduce the logistics transportation cost and improve its efficiency. So, more and more researchers study on the dynamic routing planning in the logistics to reduce the logistics transportation distance and time on the advantage of multi-agent system (MAS). Additionally, most people want to improve their own spiritual and healthy quality on the basis of promotion in life-level with the development of market economy in order to carry out the full development of people. So it leads to the prosperity of sports tour industry. But how to take full advantage of the limited sports tour resource is becoming a key problem. So, this paper researches dynamic routing planning in logistics of sports tour resource and discusses the algorithm of the shortest path through the calculation on the basis of GIS and MAS in the region of logistics to the sports tour resource. It draws a conclusion that GIS can improve efficiency and quality promptly of transportation in the sports tour resource logistics. Meanwhile, it also improves algorithm of logistics transportation routing net in sports tour resource and provides some valuable references of development of sports tour industry and promotes social harmonious and healthy development in combination with MAS. © 2011 ASCE.

Intellectual traffic system (ITS) plays an important role to improve transportation efficiency when facing the condition of traffic crowd, especially how to decide the smallest impediment among the dots in the net model. Traditionally, transportation routing planning is mainly two dimensions which is also a space orientation. Time dimension is neglected easily. So both two dimension viewpoint and time dimension principle should be considered to set up the dynamic vehicle routing (DVR). Actually, it is not simply assembled but organic combination which it means that DVR should consider road actuality, time, even and traffic currency, crowd condition etc to carry out the shortest routing, smallest time and expenditure in transportation system. On the other hand, altitude training is a kind of training method in the modern athletic sports which is very efficient as it can improve athletes' achievement under the condition of anaerobic environment and sports loads. Many sports researchers think that high-low alternate training can promote all kinds of athletes' achievement, who are from plateau location and plain area, by plenty of researches and studies. However, altitude training resource is very limited. So, this paper provides short term traffic prediction through microscopic traffic model to use altitude training resource high efficiently and qualitatively. It also tries to adjust the algorithm to plan transportation path dynamically on the basis of grasping the actuality of traffic transportation to altitude training resource being used. The result is that the transportation routing planning of altitude training resource is more practical and valuable in combination with dynamic routing planning algorithm, which is a practical test to the microscopic traffic model and dynamic routing planning in reality. The conclusion is that microscopic transportation model benefits to the development of altitude training resource and provides some valuable reference. © 2011 ASCE.

In this paper, the author proposes a moire fringe elimination algorithm which detects the Moire fringe area at first, and then adopts color interpolation for compensation. The algorithm conducts the high-pass filtering at the horizontal and vertical directions on the G component of digital clothing images and simulates the aliases of CFA sampling process in order to find out the areas with moire fringes, and then reprocesses R, B components respectively in moire areas with complete data after the horizontal interpolation of G component. Finally, the elimination of moire fringe is realized through combining the color components of three channels. The experimental results prove this method to be excessively practical as it could eliminate the moire fringe through extracting image information without affecting the quality of image.
