Hopf Algebra of Labeled Simple Graphs

A lot of combinatorial objects have a natural bialgebra structure. In this paper, we prove that the vector space spanned by labeled simple graphs is a bialgebra with the conjunction product and the unshuffle coproduct. In fact, it is a Hopf algebra since it is graded connected. The main conclusions are that the vector space spanned by labeled simple graphs arising from the unshuffle coproduct is a Hopf algebra and that there is a Hopf homomorphism from permutations to label simple graphs.

Kepler’s Conjunction for Two Strong Earthquakes in Türkiye in February 2023

This work is devoted to the study of the relationship between strong earthquakes and planetary configurations using the example of two consecutive strong earthquakes that occurred in Türkiye (Turkey), on February 6, 2023. It is shown that at the time of the earthquakes, linear alignment of the planets along the Jupiter-Venus-Sun line was observed, that is, the astronomical trigger belonged to the generalized Kepler conjunction scheme (gKc), when the Earth does not participate in the linearization scheme. It is shown that for the first earthquake that occurred at 01:17 UTC, the ratio of the distances between Jupiter-Earth and Jupiter-Mars was close to an integer value equal to 5.993. For the second earthquake that occurred on the same day at 10:25 UTC, no integer resonance ratios were detected, however, it was found that the terrestrial e UTC line at the time of the earthquake passed through the position of Mercury. Recall that the 12-hour line of the eUTC chart is always oriented towards the Sun. The conclusions of the work once again confirm the correctness of the theories of Archimedes and Kepler and convince us of the existence of a gravitational phenomenon that does not depend on the distances and masses of planets, has a pronounced inertial and wave character and does not fit into the general theory of relativity, developed in the last century by Albert Einstein.

Calculation and Analysis of Valence Electron Structure of Mo_2C and V_4C_3 in Hot Working Die Steel

Taking the hot working die steel （HWDS） 4Cr3Mo2NbVNi as an example, the phase electron structures （PES） and the biphase interface electron structures （BIES） of Mo2C and V4 C3 , which are two kinds of important carbides precipitated during tempering in steel were calculated, on the basis of the empirical electron theory of solids and molecules and the improved TFD theory. The influence of Mo2 C and V4 C3 on the mechanical properties of HWDS has been analyzed at electron structure level, and the fundamental reason that the characteristic of the PES and the BIES of carbides decides the behavior of them has been revealed.

英语篇章的主题连贯性和英语句子的移位转换

篇章连贯性(Text-coherence)是篇章语言学研究的重要课题.人们无论说话或写文章,都是根据话题和会话目的把句子通过一定的连接手段有机地结合起来.语言符号组装的线性特征规定了言者只能将语言单位在"时间线条"上进行线性的排列,构成言语链.话语中的句子如同这一链条上的环节,彼此都不是孤立的,而是首尾相顾,环环紧扣,体现了表达思想,传递信息的连续性和条理性.构成英语篇章连贯性的因素很多.Halliday在Cohesion in English 一书中把衔接手段分为五大类:照应(reference),替代(substitution),省略(ellipsis),连接词语(conjunction)。

SCATTERING OF PLANE SH-WAVE BY A CYLINDRICAL HILL OF ARBITRARY SHAPE

The problems of scattering of plane SH-wave by a cylindrical hill of arbitrary shape is studied based on the methods of conjunction and division of solution zone. The scattering wave function is given by using the complex variable and conformal mapping methods. The conjunction boundary conditions are satisfied. Furthermore appling orthogonal function expanding technique, the problems can finally be summarized into the solution of a series of infinite algebraic equations. At last, numerical results of surface displacements of a cylindrical arc hill and of a semi-ellipse hill are obtained. And those computational results are compared with the results of finite element method (FEM).

The Path of Grammaticalization for Coordinate Conjunctions and its Universality

From the study of polysemy of coordinate conjunctions, it can be found that there are grammaticalization processes from coordination to transition and from coordination to succession. It is a general evolutionary process in connective structures to go from non-specific semantic relationship to specific semantic relationship. This was caused by the cognitive tendency of approximately substituting typical functions for atypical functions.

Research on the Occurrences of Causality Conjunctions in Korean Based on Corpus

Corpus is a kind of database that may contain texts in a single language(monolingual corpus)or text data in multiple languages(multilingual corpus).Most of the words can be involved in such a database,so it is provided with significant realistic meaning for language learners.Also,the use of causality conjunction in Korean plays a more important guiding role in listening,speaking,reading and writing of Korean.However,the status with regard to the application of causality conjunction in Korean is not optimistic and the problems such as the improper use of language,lack of knowledge about conjunction by learners,short of professional Korean teaching consciousness by teachers and others are being,thereby seriously hindering the learning interests of Korean learners and educational progress.Thus,in accordance with research status at home and abroad,this paper carries out indepth analysis on the basic theory of corpus and Korean conjunction as well as the application of causality conjunction in Korean based on the corpus.And it can be found that the research on the application of causality conjunction in Korean based on corpus is with important value for both the flexible use of language and the improvement of comprehensive application ability of language.

Conjunction and Teaching Reading Skills in English

Conjunction contributes to organizing and managing stretches of discourse, indicating the way the information is arranged. Successfully identifying these discourse markers is of great benefit to the reader to extract the required information from what he/she reads, especially for the candidates who are tested for their reading abilities in a given time, for these markers give clues to the reader and make the perception easier and save a lot of time. To teach students to explore reading skills and read su...

An Analysis of Cohesive Devise in an English Text from the Perspective of Discourse Analysis

This paper analyzes the cohesion in the text"Three Days to See"from the perspective of discourse analysis.It is analyzed by cohesive devises put forward by Halliday,that is,reference,substitution and ellipsis,conjunction and lexical cohesion.It is found that all those devises have been used in the text,therefore making the text textual or"be a text".
