元代转柄高足杯及类形器刍议

转柄高足杯有侈口深腹、直口浅腹两种形制,青白釉高足杯亦有同形非转柄式类形器。通过对该类高足杯类型分析和分期梳理,探讨其文化因素构成,构筑它与唐辽宋金银和陶瓷器之间的意匠渊源及发展脉络。通过分析其功能属性,从中管窥宋元文化的承袭关系,展示有元一代文化与社会世俗性特征。

以类相动——《乐道——中国古典音乐哲学论稿》之一

中国古典乐道，基于中国古典哲学“道、形、器”与“达、类、私”之基本范畴，揭示了“以类相动”、“比类成行”的音乐以其“形”之层面的、“法式”性质的“乐式”同行、同态于万事万物，“中”长宙大宇行运之“节”之行象艺术的本质属性。墨子所谓“达而类私”，正是通过特殊的具象之私，上升到一般的抽象之达；正是通过一般的抽象之达，类归特殊的具象之私；正是通过特殊的具象之器，上升到一般的抽象之道；正是通过一般的抽象之道，形范特殊的具象之器。在这里，达是以类私的面目显现的，私是以达同的属类显现的；共相是以殊相的面目显现的，殊相是以共相的例案显现的；形而上之道是以形而下之器的面目显现的，形而下之器是以形而上之道的象征显现的。而在此种种界面之中，“形”乃是其“法式”性质的中介。就音乐艺术而言，形而上的乐道是以形而下的乐象之行态显现的，形而下的乐象是以形而上的乐道之象征显现的。而在此界面之中，形之层面的“乐式”，乃是“道”、“器”之间“法式”性质的中介。

An Application of Machine Computation for Studying Graphlike Manifolds (Ⅱ)

In this note, we designed algorithm and program for homeomorphic classification of graphlike manifolds.counted the numbers of homeomorphic classes of graphlike manifolds with respect to scores contractions of 6-vertexes and noticed a mistake in [7].

Automatically Constructing an Effective Domain Ontology for Document Classification

An effective domain ontology automatically constructed is proposed in this paper. The main concept is using the Formal Concept Analysis to automatically establish domain ontology. Finally, the ontology is acted as the base for the Naive Bayes classifier to approve the effectiveness of the domain ontology for document classification. The 1752 documents divided into 10 categories are used to assess the effectiveness of the ontology, where 1252 and 500 documents are the training and testing documents, respectively. The Fl-measure is as the assessment criteria and the following three results are obtained. The average recall of Naive Bayes classifier is 0.94. Therefore, in recall, the performance of Naive Bayes classifier is excellent based on the automatically constructed ontology. The average precision of Naive Bayes classifier is 0.81. Therefore, in precision, the performance of Naive Bayes classifier is gored based on the automatically constructed ontology. The average Fl-measure for 10 categories by Naive Bayes classifier is 0.86. Therefore, the performance of Naive Bayes classifier is effective based on the automatically constructed ontology in the point of F 1-measure. Thus, the domain ontology automatically constructed could indeed be acted as the document categories to reach the effectiveness for document classification.

Ship detection in optical remote sensing image based on visual saliency and AdaBoost classifier

In this paper, firstly, target candidate regions are extracted by combining maximum symmetric surround saliency detection algorithm with a cellular automata dynamic evolution model. Secondly, an eigenvector independent of the ship target size is constructed by combining the shape feature with ship histogram of oriented gradient(S-HOG) feature, and the target can be recognized by Ada Boost classifier. As demonstrated in our experiments, the proposed method with the detection accuracy of over 96% outperforms the state-of-the-art method. efficiency switch and modulation.

Adaptive triangular mesh coarsening with centroidal Voronoi tessellations

We present a novel algorithm for adaptive triangular mesh coarsening. The algorithm has two stages. First, the input triangular mesh is refined by iteratively applying the adaptive subdivision operator that performs a so-called red-green split. Second, the refined mesh is simplified by a clustering algorithm based on centroidal Voronoi tessellations (CVTs). The accuracy and good quality of the output triangular mesh are achieved by combining adaptive subdivision and the CVTs technique. Test results showed the mesh coarsening scheme to be robust and effective. Examples are shown that validate the method.

Multipotent mesenchymal stromal cells are fully permissive for human cytomegalovirus infection

Congenital human cytomegalovirus(HCMV) infection is a leading infectious cause of birth defects.Previous studies have reported birth defects with multiple organ maldevelopment in congenital HCMV-infected neonates. Multipotent mesenchymal stromal cells(MSCs) are a group of stem/progenitor cells that are multi-potent and can self-renew, and they play a vital role in multiorgan formation. Whether MSCs are susceptible to HCMV infection is unclear. In this study, MSCs were isolated from Wharton's jelly of the human umbilical cord and identified by their plastic adherence, surface marker pattern, and differentiation capacity. Then, the MSCs were infected with the HCMV Towne strain, and infection status was assessed via determination of viral entry,replication initiation, viral protein expression, and infectious virion release using western blotting,immunofluorescence assays, and plaque forming assays. The results indicate that the isolated MSCs were fully permissive for HCMV infection and provide a preliminary basis for understanding the pathogenesis of HCMV infection in non-nervous system diseases, including multi-organ malformation during fetal development.
