A New Complex Number Definition: Distinct Imaginary Numbers
Authors: Pakdemirli Mehmet 
Published: January 2023

Abstract
A new base complex number is defined. To distinguish it from the usual complex number i, the name “distinct imaginary number” is proposed with a shorter referral of “dimaginary number” and symbol j. The complex number with this new base included can be referred to as dicomplex numbers (distinct complex numbers) accordingly. Based on the new definition, the basic arithmetic operations are handled first. Taylor series expansions with the new complex number are given next. Application areas such as finding roots of polynomials, analytical geometry in three and higher dimensional spaces are discussed. The new definition extends the usual two-dimensional complex plane into three and higher dimensional spaces.

Published: January 2023

Abstract

There is growing use of technology and presence of people online globally. Electronic platforms have also become the avenue for expression of opinions on emerging issues by people. However, some of the posts or comments posted online could sometimes be negative with far reaching effects on the community. The use of machine learning algorithms through sentiment analysis offers means that could be used to mine data and analyse opinions that emanate from online to reach decisions or monitor ethical compliance. This study presents an approach that uses a Multimodal fusion with Recurrent Neural Networks (M-RNN) to predict opinions through decision making and real time monitoring. The dataset was trained using standard methods like a decision tree classifier, and the M-RNN model achieved an accuracy of roughly 82.80%. The training model's relative average error was close to 0.503% when using the M-RNN methodology, and the training cycle only needs to be repeated 250 times to achieve satisfactory results, a figure that is low when compared to other conventional methods.

Published: January 2023

Writing is the most complicated skill among other language skills. In the writing activity, the students have to invent ideas and organize them into sentences and paragraphs that will be clear for readers. Feedback is crucial to give significant improvement to student's writings. Peers and maybe various can provide feedback. This study's objective was to describe the types of feedback used by students of the Intermediate Writing Class in writing an argumentative paragraph. Descriptive qualitative was the design of research. The subjects of this research are A1 and A4 Intermediate Writing course students of the English language Education Study Program of Lambung Mangkurat University. The data were collected through observation and document analysis. The data were then analyzed through three steps: familiarizing and organizing, coding, and interpreting and representing. The result was found that the students used several feedback types, namely written feedback as responding and written feedback as correcting. Written feedback as correcting used by the students consists of direct feedback, metalinguistic feedback, and unfocused feedback. From some of the metalinguistic feedback that some students used, they were using the grammatical description. Some of the metalinguistic feedback that some students used was the metalinguistic explanation (grammatical description). There was no metalinguistic feedback of the error code. There was only one student who used unfocused feedback. In conclusion, the students used four feedback types: written feedback as responding, written feedback as correcting, or written corrective feedback consisting of direct feedback, metalinguistic feedback, and unfocused feedback. Written feedback as responding is the feedback that the students used most while doing peer feedback. The students need to look for more information and explanation or feedback from the teachers and their friends and give feedback while doing peer feedback properly to not only use one type of feedback.

Authors: Herminingsih Dwi Ima 
Published: January 2023

The purpose of doing research is to have the investigation on the students’ belief when Duo lingo application is applied in the class of vocabulary and to describe the justification of the advantages using the Duo lingo to empower the vocabulary enrichment. The students of English Study Program in State Islamic College as Pre Service –teachers have participated in this study. The data were collected by the questionnaire distribution and the interview methods. The data analysis uses the qualitative description. The result of the study exposes the facts that the respondents agree the Duo lingo can facilitate the vocabulary learning achievement. The medium labelled Duo lingo makes the students easy and interesting in learning the English word knowledge. The interview with the sample of informants suggests the testimony that the young learners can use the app overtime as far as they want. They are free to set or make up the schedule of lesson session. One more meaningful thing found in the application is that the English is spoken by the native speaker. By performing the English of the native speaker can be a model or master for the students. They get the chance to exercise repeating the word or the sentence spoken by the native speaker correctly.

Metáfora e sexualidade da mulher:
Authors: Da Silva Balieiro Anndra Karolina , Pothin Narzetti Costa Claudiana Nair 
Published: January 2023

Este artigo apresenta uma análise sobre o funcionamento do discurso antifeminista, notadamente sobre os efeitos de sentidos em torno do objeto discursivo “revolução sexual” cuja origem pode ser relacionada ao discurso feminista. O referencial teórico e metodológico é a Análise de Discurso Materialista, partindo dos trabalhos de Michel Pêcheux (1988; 1990; 1999; 2006; 2011; 2014) e seu grupo. O corpus consiste em quatro publicações de páginas autointituladas antifeministas, advindas do Instagram e do Facebook. Destas publicações, destacamos sequências discursivas (COURTINE, 2009) que retomam o objeto “revolução sexual” e identificamos: uma cadeia de significantes que no discurso antifeminista metaforiza-a em “liberação”, “libertinagem”, “promiscuidade” e um conjunto de supostas consequências negativas do movimento feminista para as mulheres e, consequentemente, para a sociedade. Concluímos que a sexualidade da mulher emerge na discursividade antifeminista em relação de franca oposição com o que foi/é defendido pela discursividade feminista e com formação ideológica neoconservadora e neoliberal.

Authors: Liu Xiaochuang , Wang Yuanyuan , Zhang Yanyan , Jiang Hui , Huo Xingxing , Liu Rui 
Published: January 2023

Background:
Xinfeng capsule (XFC) is a well-known drug against rheumatoid arthritis
(RA). However, the combination mechanisms of XFC on RA remain unclear.

Objective:
The purpose of this study is to explore the mechanisms of XFC against RA in terms of
compounds, targets, and signaling pathways via network pharmacology.

Methods:
The bioactive compounds and potential targets of XFC were extracted from TCMSP and
BATMAN-TCM database, and the putative RA-related targets were determined from the DisGeNET,
PHGKB, PharmGKB, and CTD database. The approach of protein-protein interaction, gene ontology
analysis, and kyoto encyclopedia of genes and genomes pathway enrichment analysis were constructed,
respectively. In animal experiments, we evaluated the expression of core targets.

Results:
We found that XFC handled 30 active compounds and 131 common target genes. Among
them, mairin, folic acid, cholesterol, and triptolide in XFC were selected as the central active compounds
against RA. The mechanisms of XFC on RA which concerned critical targets were protein
kinase B (AKT1) and tumor necrosis factor (TNF). In vivo, we found that the expression levels of
AKT1 and TNF in the modeling group were significantly increased but reversed by XFC.

Conclusion:
The combination mechanisms of XFC were elucidated in terms of components and
targets and signaling pathways, which may be related to inhibiting the proliferation of synovial
cells and inflammation.

Published: January 2023

Introduction:Cancer is the major cause of death globally. Cancer can be treated with naturally occurring Curcumin nuclei. Curcumin has a wide range of biological actions, including anti-inflammatory and anti-cancer properties. Even though it is an effective medicinal entity, it has some limitations such as instability at physiological pH and a weak pharmacokinetic profile due to the β-diketone moiety present in it. To overcome this drawback, research was carried out on mono-ketone moieties in curcumin, popularly known as mono-carbonyl curcumin.Objective:The present review focuses on different synthetic schemes and Mono-carbonyl curcumin derivative's Structure-Activity Relationship (SAR) as a cytotoxic inhibitory anticancer agent. The various synthetic schemes published by researchers were compiled.Methods:Findings of different researchers working on mono-carbonyl curcumin as an anticancer have been reviewed, analyzed and the outcomes were summarized.Results:The combination of all of these approaches serves as a one-stop solution for mono-car-bonyl curcumin synthesis. The important groups on different positions of mono-carbonyl curcumin were discovered by a SAR study focused on cytotoxicity, which could be useful in the designing of its derivatives.Conclusion:Based on our examination of the literature, we believe that this review will help re-searchers design and develop powerful mono-carbonyl curcumin derivatives that can be proven essential for anticancer activity.

Published: January 2023

Abstract:Lymphatic muscle cell (LMC) contractility and coverage of collecting lymphatic vessels (CLVs) are integral to effective lymphatic drainage and tissue homeostasis. In fact, defects in lymphatic contractility have been identified in various conditions, including rheumatoid arthritis, inflammatory bowel disease, and obesity. However, the fundamental role of LMCs in these pathologic processes is limited, primarily due to the difficulty in directly investigating the enigmatic nature of this poorly characterized cell type. LMCs are a unique cell type that exhibit dual tonic and phasic contractility with hybrid structural features of both vascular smooth muscle cells (VSMCs) and cardiac myocytes. While advances have been made in recent years to better understand the biochemistry and function of LMCs, central questions regarding their origins, investiture into CLVs, and homeostasis remain unanswered. To summarize these discoveries, unexplained experimental results, and critical future directions, here we provide a focused review of current knowledge and open questions related to LMC progenitor cells, recruitment, maintenance, and regeneration. We also highlight the high-priority research goal of identifying LMC-specific genes towards genetic conditional- inducible in vivo gain and loss of function studies. While our interest in LMCs has been focused on understanding lymphatic dysfunction in an arthritic flare, these concepts are integral to the broader field of lymphatic biology, and have important potential for clinical translation through targeted therapeutics to control lymphatic contractility and drainage.Discussion:While our interest in LMCs has been focused on understanding lymphatic dysfunction in an arthritic flare, these concepts are integral to the broader field of lymphatic biology, and have important potential for clinical translation through targeted therapeutics to control lymphatic contractility and drainage.

Policy Requirements in China: A Retrospective Cohort Study
Authors: Tang Li , Li Chun-Rong , Luo Tong-Yong , Lin Yong-Hong , Song Wei , Wang Zhiqiang , Lan Qingfu , Qin Shiji 
Published: January 2023

Background:
China officially launched the universal two-child policy in January 2016. No
studies in China have examined the characteristics of pregnant women since the implementation of the
new family planning policy.

Methods:
We conducted a retrospective cohort study in Chengdu, China, to examine pregnant women's
sociodemographic and obstetric characteristics satisfying the new policy requirements. Two thousand
pregnant women were enrolled in the case group, 2016-2017. The comparison group included
2,000 pregnant women from the same institutions. Maternal and clinical information was extracted
from medical records.

Results:
Compared to comparisons, the case group tended to have a higher household income and
work in a non-state-owned enterprise/institution. Additionally, cases were more likely to be older
(OR=1.36; 95% CI 1.09-1.70), have a history of cesarean section (OR=31.68; 95% CI 24.76-40.54),
and suffer from gestational hypertension (OR=3.35; 95% CI 1.56-7.19), gestational diabetes mellitus
(OR=1.61; 95% CI 1.24-2.10) and placenta previa (OR=4.45; 95% CI 2.70-7.34) than comparisons.

Conclusion:
We suggest emphasizing the importance of reproductive counseling and assessment, particularly
targeting those satisfying the universal two-child policy requirements.
Nephrotoxin Exposure and Acute Kidney Injury in Adults
Authors: Griffin Benjamin R. , Wendt Linder , Vaughan-Sarrazin Mary , Hounkponou Hermann , Reisinger Heather S. , Goldstein Stuart L. , Jalal Diana , Misurac Jason 
Published: January 2023

Background
Rates of nephrotoxic AKI are not well described in adults due to lack of a clear definition, debate over which drugs should be considered nephrotoxins, and illness-related confounding. Nephrotoxic Injury Negated by Just-in Time Action (NINJA), a program that reduces rates of nephrotoxic AKI in pediatric populations, may be able to address these concerns, but whether NINJA can be effectively applied to adults remains unclear.

Methods
In this retrospective cohort study conducted at the University of Iowa Hospital, we included adult patients admitted to a general hospital floor for ≥48 hours during 2019. The NINJA algorithm screened charts for high nephrotoxin exposure and AKI. After propensity score matching, Cox proportional hazard modeling was used to evaluate the relationship between nephrotoxic exposure and all-stage AKI, stage 2–3 AKI, or death. Additional analyses evaluated the most frequent nephrotoxins used in this population.

Results
Of 11,311 patients, 1527 (16%) had ≥1 day of high nephrotoxin exposure. Patients with nephrotoxic exposures subsequently developed AKI in 29% of cases, and 22% of all inpatient AKI events met nephrotoxic AKI criteria. Common nephrotoxins were vancomycin, iodinated contrast dye, piperacillin-tazobactam, acyclovir, and lisinopril. After propensity score matching, Cox proportional hazard models for high nephrotoxin exposure were significantly associated with all AKI (hazard ratio [HR] 1.43, 1.19–1.72, P<0.001), stage 2–3 AKI (HR 1.78, 1.18–2.67, P=0.006), and mortality (HR 2.12, 1.09–4.11, P=0.03).

Conclusions
Nephrotoxin exposure in adults is common and is significantly associated with AKI development, including stage 2–3 AKI.

Недавно вышедшая монография посвящена дипломату, первому уполномоченному НКИД Советской России в Монголии Отто Ивановичу Макстенеку, и является результатом плодотворной работы авторитетных ученых двух стран — России и Монголии, представляющих два научных учреждения — Институт монголоведения, буддологии и тибетологии СО РАН и Институт истории и этнологии Монгольской академии наук. Цитата, вынесенная в заголовок рецензии, взята из Введения монографии [Курас и др. 2022: 8]. Действительно, о первом уполномоченном НКИД РСФСР в Урге до недавнего времени было мало сведений, его имя «отсутствует в справочниках и в энциклопедиях по истории Октябрьской революции, Гражданской и в трехтомном дипломатическом словаре» [Курас и др. 2022: 8], имеются лишь краткие упоминания, подробно изложенные в рубрике «Российско-монгольская историография места и роли личности в монгольской революции 1921 г. рецензируемого издания [Курас и др. 2022: 9–35]. Авторы монографии восполнили эту лакуну, подробно раскрыли важную роль О. И. Макстенека — революционную, дипломатическую, общественную — в контексте событий, происходивших в Монголии и Советской России в этот период. Его автобиография [Курас и др. 2022: 155–166] представлена в рубрике Приложения [Курас и др. 2022: 134–183]. В данной рубрике даны всего семь, весьма солидных, на наш взгляд, Приложений: кроме упомянутой автобиографии, мартиролог жертв политических репрессий, справка об аресте Макстенека, итоги деятельности уполномоченного Наркоминдела в Монголии О. И. Макстенека с 1 июня 1920 по март 1921 г., протокол заседания Временного революционного правительства Монголии с участием представителей РСФСР, протокол заседания президиума Малого хурала, справка о Центральном совете «Общества бывших политкаторжан и ссыльнопоселенцев». Уже одно лишь перечисление заголовков с содержательной частью всех Приложений свидетельствует, какую грандиозную и кропотливую работу провели ученые.
