Chao Yuen Ren (1892–1982)
No full textY. R. Chao is easily the most famous linguist to have come out of China. Born before the end of the last dynasty in China, he received a traditional Confucian education, but was also one of the first Chinese people to be sent to the West for training in modern Western science (under the Boxer Indemnity Fund). The remarkable breadth and scope of his studies included physics, mathematics, linguistics, musical and literary composition, and translation, and he was a pioneer in many of these fields
Entanglement and quantity in quantum space - About quantum measurement (II)
No full textAs a continuation and extension of "quantity in phase space" "quantity in quantum space" is introduced. With that, the disappearing of quantum interference discussed in a previous paper [S. Durr, et al., Nature 395 (1998) 33] is explained in the same spirit as our recent papers [Ren De-Ming, Commun. Theor. Phys. (Beijing, China) 41 (2004) 685, 833].Physics, MultidisciplinarySCI(E)中国科学引文数据库(CSCD)1ARTICLE133-364

Evolutionary histories of legume genomes and mechanisms of genome remodeling
No full textEvolutionary genomics analysis of plants aims to reveal and help us to understand the history of genome evolution that plants have undergone. So far, many specific topics and questions of genome evolution have been studied and answered. However, there are still a large number of questions to which the answers are unknown or not clear. In this dissertation, I focus on two specific topics of evolutionary genomics: (1) genome size evolution following genomic rearrangements in plants; (2) ancestral genome reconstruction in legumes.
Using a model of two wild peanut relatives in which one genome experienced large rearrangements, we find that the main determinant in genome size reduction is a set of inversions which experienced subsequent net sequence removal in the inverted regions. We observe a general pattern in which sequence is lost more rapidly at newly distal (telomeric) regions than it is gained at newly proximal (pericentromeric) regions – resulting in net sequence loss in the inverted regions. The major driver of this process is recombination, determined by the chromosomal location. Any type of genomic rearrangement that exposes proximal regions to higher recombination rates can cause genome size reduction by this mechanism. Sequence loss in those regions was primarily due to removal of transposable elements. Illegitimate recombination is likely the major mechanism responsible for the sequence removal, rather than unequal intrastrand recombination. We also measure the relative rate of genome size reduction in these two Arachis diploids. We also test our model in other plant species and find that it applies in all cases examined, suggesting our model is widely applicable.
Inversions occurring in tetraploid cultivated peanut after the polyploidization event provide us an excellent opportunity to examine the model of genome size reduction following genomic rearrangements in polyploidy. It is also a good opportunity to understand the genome size reduction process at its early stage, since the inversions are quite recent (likely younger than 10,000 years). We observe that the model of genome size reduction still holds in the recently-derived tetraploid peanut as it does in the much earlier-diverging diploid progenitors. We find that the genome size reduction process starts with differences in very long sequence deletions and then spreads to mid-length sequence deletions later. We measure the relative rate of size reduction of the inverted region in tetraploid peanut, finding that it is higher than the rates calculated in our previous study between Arachis diploids. We argue this is because the rate of size reduction is more rapid in the early generations after the inversion.
We describe the reconstruction of a hypothetical ancestral genome for the papilionoid legumes, in order to help us better understand the evolutionary histories of these legumes. We use a novel method for identifying informative markers, to reconstruct the ancestral genomes for selected legume species, including Glycine max, which has a recent exclusive WGD event. We infer that the reconstructed most recent common ancestor of all selected legume species (all within the Papilionoideae) has 9 chromosomes. The model then predicts that chromosome numbers reduced to 8 in Medicago truncatula and Cicer arietinum separately, through two separate single fusion events. In Lotus japonicus, a series of rearrangement events is the major cause of the chromosome number reduction to 6. We infer that the chromosome number increased mostly independently in Cajanus cajan, Glycine max, Phaseolus vulgaris and Vigna radiata. In Arachis (A. duranensis and A. ipaensis), there was an increase in chromosome number prior to their divergence. The chromosome structural evolution described here is consistent with the phylogenetic distribution of a large collection of chromosome counts in the legumes.</p
从《任雨农全集》探知任雨农的教育思想(A Study Of The Educational Thoughts From The “Complete Works Of Ren Yunong”)
No full textThis paper focuses on Ren YuNong, the Chinese School Teacher of Malaysia,study about his work and struggle on the Chinese Education, analyses his educational ideal and experiences fighting for Chinese Education, as well as his influence on education and cultural. The author will sort out his life stories, find out the origin of his educational thoughts, and prove that Ren YuNong’s educational thought has Confucian connotation. Chinese calligraphy is developed with the development of Chinese education and other fine arts education. The author will elaborate on this subject, Ren YuNong how to express his humanistic spirit of cultural calligraphy, irrigation it in educational thinking and highlight the role of cultural educators. Then, taking Ren Younong as the research object of this thesis, from Ren YuNong's Collected Books volume one, two and three as the chief source to discover Ren YuNong's educational thoughts. The author will interpret the responsibility of cultural education from Ren YuNong through three categories, which is: Chinese education, issue of promoting Chinese and promote calligraphy. Through this representative case study, the author attempts to study in detail of how Chinese education survive in Malaysia's sensitive ethnic politics, summarizes the causes and experiences of Malaysian Chinese education as a model of overseas Chinese education, and analyzes its development prospects. The author also hopes to promote the study of Malaysian Chinese education at home and abroad. v Finally, summing up the influences of Ren YuNong on Chinese education and his contribution, it is confirmed that heis an important figure in Malaysian’s history, especially his participation in the development of Chinese education in Malaysia
Cheirocratidae Ren 2006
No full textCheirocratidae Ren, 2006 Cheirocratids Barnard & Barnard, 1983: 597, fig. 15. Cheirocratidae Ren, 2006, 259. Diagnosis. Eyes round. Antenna 1 not longer than the peduncle of antenna 2, with sparse slender setae. Antennae without calceoli. Mandible palp article 1 about 3 x longer than broad. Maxilliped outer plate large, longer than palp article 2, not longer than article 3. Coxae 1–3 large, all similar in size. Gnathopods 1–2 simple or subchelate. Pereopods 5–6 basis slightly expanded. Pereopods 6–7 similar in structure. Pereopod 5 shorter than pereopod 6. Urosomite 2, with mid-dorsal serration and simple or robust setae (except Incratella). Uropods 1–2, apices of rami with robust setae. Uropod 1 peduncle without basofacial robust seta. Uropod 3 biramous; peduncle long, at least 2 x as long as broad. Telson deeply cleft. Included genera. Cheirocratidae includes 7 genera: Casco Shoemaker, 1930; Cheirocarpochela Ren & Andres, 2006; Cheirocratella Stephensen, 1940; Cheirocratus Norman, 1867; Degocheirocratus G. Karaman, 1985; Incratella Barnard & Drummond, 1982; Prosocratus Barnard & Drummond, 1982. Remarks. Ren (2006) used the name Cheirocratidae and attributed the authorship to Barnard & Barnard (1983). However, Barnard & Barnard (1983), only referred to an informal group. Ren (2006) used the formal name Cheirocratidae, provided a diagnosis and therefore becomes the author of the family. Cheirocratidae appears to be most similar to the Maeridae Krapp-Schickel, 2008. There are several significant differences between these taxa. In cheirocratids antenna 1 is shorter than the peduncle of antenna 2 whereas in the Ceradocus group it is subequal in length or longer than antenna 2. In general, gnathopod morphology is very different between these groups. For instance gnathopod 1 is almost always simple in male and female cheirocratids and subchelate in the Maeridae. Within the cheirocratids gnathopod 2 is usually simple in females and subchelate in males whereas in melitids it is subchelate in both sexes. In both families the male gnathopod 2 is usually larger than gnathopod 1. The shape of the anterior margin in the heads is also different. Although both families have an anteroventral notch, in the cheirocratids the anteroventral corner of the head is distinctively subquadrate. An apparent autapomorphy that distinguishes cheirocratids from all other amphipods, except the Talitridae, is that antenna 1 is shorter than the peduncle of antenna 2. These shortened antennae appear to be independently derived in the two families. A second autapomorphy appears to be the significantly elongated first article of the mandibular palp, which can be up to 3 x as long as broad. Incratella Barnard & Drummond, 1982 has always been considered to be the senior synonym of Cheirocratus (Indiocratus) Ledoyer, ‘1982’. It was unclear which taxon was published first. In fact the date of publication for Cheirocratus (Indiocratus) Ledoyer, ‘1982’ was actually January 1983 (Aberlenc (Ed, Faune de Madagascar), pers. comm.), thus Incratella has preference.Published as part of Coleman, Charles Oliver & Lowry, James K., 2009, Cheirocratidae *, pp. 333-338 in Zootaxa 2260 (1) on page 334, DOI: 10.11646/zootaxa.2260.1.14, http://zenodo.org/record/532177
Performance study of single-query motion planning for grasp execution using various manipulators
No full textThis paper identifies high performing motion planners among three manipulators when carrying out grasp executions. Simultaneously, this paper presents useful benchmarking data. Sampling-based motion planners of OMPL available for use in MoveIt! are compared by performing several grasping-related motion planning problems. The performance of the planners is measured by means of solved runs, computing time and path length. Based on the results, recommendations are made for planner choice that shows high performance for the used manipulators.Accepted Author ManuscriptRobot Dynamic
