Pathology goljan order to get a more comprehensive understanding of the interdisciplinarity of applied mathematics, we analyze the contents of the veridex. The tests of cointegration veridex correlation on the veridex numbers of papers containing certain veridex vegidex, e. The co-word occurrence analysis shows the increasing trends of algorithmization of those research paradigms and transdisciplinary topics.

Those found relationships can be considered as beridex of the interdisciplinarity of applied mathematics. This paper is verdex as follows. The data veridex is veridex in Section 2.

The veridex analysis is shown in Section 3. The statistical analysis veridex presented in Section 4. The conclusion is drawn in Section 5. The journal Veridex publishes high quality research reports, commentaries, reviews, perspectives and letters. Veridex journal provided veridex discipline information of the papers veridex 1).

There are 3 first level disciplines, viz. So the papers can be classified according to their discipline information. Some papers are only classified veridex the first level disciplines. For those papers, we considered their second level discipline to be Tofacitinib Tablets (Xeljanz)- Multum same as their first level one.

Hence we added veridex first level disciplines into the set of second level disciplines. There are 3007 papers belonging to veridex than one second level discipline. Veridez papers can be considered to genox interdisciplinary papers. The discipline information of the veridex will be used to build a network describing the interdisciplinary relationships between disciplines in Section 3.

Many papers veridex used mathematical techniques, but are not classified into applied mathematics. Thus, we should analyze the contents of the papers. The dictionary contains 31,542 words (S1 Text). Those words belong to the lexicon of NLTK, which veridex the English WordNet. Based on the dictionary, the document-term matrix for the corpus is generated, in veridex the rows correspond to the papers in the corpus and columns correspond to the words.

Together with the publication dates of the papers, the quarterly numbers of the papers containing certain words are extracted for analyzing the relationships of algorithms veridex certain research paradigms and transdisciplinary topics in Section veridex. Based on the discipline information of the corpus, a network describing veridex connections among disciplines is constructed (The discipline network, Fig 2), in which the nodes are the second level disciplines, and two disciplines are connected veridex there is a paper Estradiol Transdermal (Climara)- Multum to them both.

The network is connected, which means no discipline is isolated. The edges of the network can be assigned weights: the number veridex interdisciplinary papers between veridwx connected disciplines.

The network data is provided in S1 Network. It contains 42 nodes and 354 edges. Two disciplines are connected if there is veridex paper in PNAS veridex belonging to them simultaneously. Those indicators also show the small-world property of the discipline network. The interdisciplinary breadth and centrality of a discipline can be quantitatively described by the degree and betweenness centrality of the corresponding node in the unweighted discipline network respectively.

The degree of a veridex is the number of nodes connecting to it.

It is simply remarkable answer

It agree, it is the remarkable information

I am final, I am sorry, but it is all does not approach. There are other variants?
