AbstractIn the last few years, the number of applications of the multidimensional fuzzy arithmetic (MFA) and the multidimensional interval arithmetic is expanding. Authors of new papers about applications of MFA are often faced with comments from other researchers, especially the gradual arithmetic (GA) proponents, that the horizontal membership function (HMF) used in MFA is the same as the inverse membership function (InvMF) used in GA, and that MFA itself adds nothing new to the fuzzy arithmetic. This view leads to unfair evaluations of scientific papers about MFA applications submitted to scientific journals and to unnecessary disagreements between MFA and GA proponents. The purpose of this paper is to carefully analyze the two types of functions (HMF and InvMF) and to demonstrate their important differences. The basic and decisive difference is the dimensionality of both functions, which is illustrated by examples. It should also be added that HMF has proven its usefulness in solving difficult problems such as: systems of fuzzy equations or fuzzy differential equations, which is confirmed by numerous publications. The paper enable the reader to have a deeper understanding of the multidimensional fuzzy arithmetic.

In this paper, a computer implementation to evaluate the arithmetic operations on two fuzzy numbers with linear membership functions has been developed. The fuzzy arithmetic approached by the interval arithmetic is used here. The algorithm of the developed method with a numerical example is also provided. Using this method four basic arithmetic operations between any two TFNs can be evaluated without complexity. Keywords: Fuzzy arithmetic, Fuzzy number, Membership Function, Interval arithmetic, α - cut.

ABSTRACT Inaccurate data in scientific papers can result from honest error or intentional falsification. This study attempted to determine the percentage of published papers that contain inappropriate image duplication, a specific type of inaccurate data. The images from a total of 20,621 papers published in 40 scientific journals from 1995 to 2014 were visually screened. Overall, 3.8% of published papers contained problematic figures, with at least half exhibiting features suggestive of deliberate manipulation. The prevalence of papers with problematic images has risen markedly during the past decade. Additional papers written by authors of papers with problematic images had an increased likelihood of containing problematic images as well. As this analysis focused only on one type of data, it is likely that the actual prevalence of inaccurate data in the published literature is higher. The marked variation in the frequency of problematic images among journals suggests that journal practices, such as prepublication image screening, influence the quality of the scientific literature.

By significantly changing the evaluation criteria set out in the Rules on Conditions for Election in Scientific Titles in 2017, law field scientists began to observe the publication of their papers in a way that has not yet been introduced - through scoring, new categorization and indexing in Scopus and WoSCC bases. At the same time, this required the adaptation of scientific journals to the same proclaimed conditions. This is why the characteristics of Croatian legal-scientific reality, in terms of paper publication, have become conditioned by the efforts to undergo standardization and metrics. At the same time this happens without respecting the inherent fundamental characteristic of law as a discipline. One of the basic ones is primarily national orientation. The paper provides a normative analysis of the previous and positive conditions related to the evaluation of the published scientific papers in the field of law, as well as the results of the research obtained by examining law scientists at the four law faculties in the Republic of Croatia. Research findings bring the features of the previous modality of publishing on behalf of legal scientists in Croatia in the light of the new conditions and indicate that the changes presented will affect future publication intention in the field of law.

The ability to write and publish articles in scientific journals is part of the professional competence of the teacher. The problem is that many teachers have not mastered the skills of writing scientific papers. As a result, many teachers find it difficult to advance in rank, especially for promotion after IV/a. This paper describes a community service activity sponsored by Riau University lecturers which aims to help teachers improve their scientific writing skills. Community Service Activities were performed at a SMAIT (Islamic Integrated High School) in Pekanbaru, Riau. This paper further explains the concept of the workshop, the content of the workshop materials, and the effectiveness of the workshop. This workshop lasted for two months with three face-to-face training sessions. The rest was done online via the Google Classroom platform. The material content covers the basic principles of scientific writing, the steps for writing scientific journals, how to cite and make references, including how to automatically quote from reference manager applications such as Mendeley, and how to submit articles through the Online Journal System (OJS). Data from the survey conducted at the end of the community service activity showed that, in general, this activity was well and effectively carried out. The majority of participants (72.7%) stated that their motivation to write increased after attending the training. Their knowledge of writing scientific articles have improved after training. Their ability in writing scientific journals is also relatively better than before following this structured workshop.

<p><em>One form of evaluation that can be done to determine the contribution of an institution in conducting research activities is to measure the productivity of researchers through scientific publications. Publication productivity or also called research output or research productivity is one indicator of research performance or research performance. A researcher is said to have high productivity if many researchers produce scientific papers and are published in scientific journals. Contribution of research and development results is also intended for a better Indonesia. And without fail, it is also important to have input in making policies for publication of publications, as well as research planning, including providing the latest sources of information in research and development.</em><em></em></p>

AbstractIt is common practice in scientific journals to print genus and species names in italics. This is not only historical as species names were traditionally derived from Greek or Latin. Importantly, it also facilitates the rapid recognition of genus and species names when skimming through manuscripts. However, names above the genus level are not always italicized, except in some journals which have adopted this practice for all scientific names. Since scientific names treated under the various Codes of nomenclature are without exception treated as Latin, there is no reason why names above genus level should be handled differently, particularly as higher taxon names are becoming increasingly relevant in systematic and evolutionary studies and their italicization would aid the unambiguous recognition of formal scientific names distinguishing them from colloquial names. Several leading mycological and botanical journals have already adopted italics for names of all taxa regardless of rank over recent decades, as is the practice in the International Code of Nomenclature for algae, fungi, and plants, and we hereby recommend that this practice be taken up broadly in scientific journals and textbooks.

In real world physical applications purpose, it is complicated to acquire an exact solution of fuzzy differential equations due to complexities in fuzzy arithmetic and therefore creating the need for the use of reliable and efficient techniques in the solution of fuzzy differential equations. The purpose of this research paper is to utilize the reliable analytic approach of homotopy perturbation Sumudu transform method for better understanding of systems of non-linear fuzzy integro-differential equations, while using the concept of fuzzy parameter in certain dynamical problems to remove the hurdles faced in numerical approach. These mathematical models are of great interest in engineering and physics. Some numerical examples are also given to demonstrate the efficiency and superiority of the method, followed by graphical representation of the comparison of exact and approximated solution by using Maple 2017

According to our collections of literature, about 400 scientific papers dealing with Chinese bryophytes have been published in China and abroad during 1990’s. Among these, more than 50 % were published in different scientific journals in China and often written in Chinese with English abstract, which are not well known and assessable for foreign bryologists. Therefore, in addition to previous Chinese literature I-III (Cao et al. 1990, Li et Zhang 1993, 1994), we present the fourth part of Chinese literature herewith. It is hoped that this up-dated list will provide useful information for all people who are interested in bryological research.
