Authors: Obeid Jihad S , Dahne Jennifer , Christensen Sean , Howard Samuel , Crawford Tami , Frey Lewis J , Stecker Tracy , Bunnell Brian E
Published: July 2020

BACKGROUND

Suicide is an important public health concern in the United States and around the world. There has been significant work examining machine learning approaches to identify and predict intentional self-harm and suicide using existing data sets. With recent advances in computing, deep learning applications in health care are gaining momentum.

OBJECTIVE

This study aimed to leverage the information in clinical notes using deep neural networks (DNNs) to (1) improve the identification of patients treated for intentional self-harm and (2) predict future self-harm events.

METHODS

We extracted clinical text notes from electronic health records (EHRs) of 835 patients with International Classification of Diseases (ICD) codes for intentional self-harm and 1670 matched controls who never had any intentional self-harm ICD codes. The data were divided into training and holdout test sets. We tested a number of algorithms on clinical notes associated with the intentional self-harm codes using the training set, including several traditional bag-of-words–based models and 2 DNN models: a convolutional neural network (CNN) and a long short-term memory model. We also evaluated the predictive performance of the DNNs on a subset of patients who had clinical notes 1 to 6 months before the first intentional self-harm event. Finally, we evaluated the impact of a pretrained model using Word2vec (W2V) on performance.

RESULTS

The area under the receiver operating characteristic curve (AUC) for the CNN on the phenotyping task, that is, the detection of intentional self-harm in clinical notes concurrent with the events was 0.999, with an F1 score of 0.985. In the predictive task, the CNN achieved the highest performance with an AUC of 0.882 and an F1 score of 0.769. Although pretraining with W2V shortened the DNN training time, it did not improve performance.

CONCLUSIONS

The strong performance on the first task, namely, phenotyping based on clinical notes, suggests that such models could be used effectively for surveillance of intentional self-harm in clinical text in an EHR. The modest performance on the predictive task notwithstanding, the results using DNN models on clinical text alone are competitive with other reports in the literature using risk factors from structured EHR data.
Using Structural Equation Modelling in Routine Clinical Data on Diabetes and Depression: Observational Cohort Study (Preprint)
Authors: Ronaldson Amy , Freestone Mark , Zhang Haoyuan , Marsh William , Bhui Kamaldeep
Published: July 2020

BACKGROUND

Large data sets comprising routine clinical data are becoming increasingly available for use in health research. These data sets contain many clinical variables that might not lend themselves to use in research. Structural equation modelling (SEM) is a statistical technique that might allow for the creation of “research-friendly” clinical constructs from these routine clinical variables and therefore could be an appropriate analytic method to apply more widely to routine clinical data.

OBJECTIVE

SEM was applied to a large data set of routine clinical data developed in East London to model well-established clinical associations. Depression is common among patients with type 2 diabetes, and is associated with poor diabetic control, increased diabetic complications, increased health service utilization, and increased health care costs. Evidence from trial data suggests that integrating psychological treatment into diabetes care can improve health status and reduce costs. Attempting to model these known associations using SEM will test the utility of this technique in routine clinical data sets.

METHODS

Data were cleaned extensively prior to analysis. SEM was used to investigate associations between depression, diabetic control, diabetic care, mental health treatment, and Accident & Emergency (A&E) use in patients with type 2 diabetes. The creation of the latent variables and the direction of association between latent variables in the model was based upon established clinical knowledge.

RESULTS

The results provided partial support for the application of SEM to routine clinical data. Overall, 19% (3106/16,353) of patients with type 2 diabetes had received a diagnosis of depression. In line with known clinical associations, depression was associated with worse diabetic control (β=.034, P<.001) and increased A&E use (β=.071, P<.001). However, contrary to expectation, worse diabetic control was associated with lower A&E use (β=–.055, P<.001) and receipt of mental health treatment did not impact upon diabetic control (P=.39). Receipt of diabetes care was associated with better diabetic control (β=–.072, P<.001), having depression (β=.018, P=.007), and receiving mental health treatment (β=.046, P<.001), which might suggest that comprehensive integrated care packages are being delivered in East London.

CONCLUSIONS

Some established clinical associations were successfully modelled in a sample of patients with type 2 diabetes in a way that made clinical sense, providing partial evidence for the utility of SEM in routine clinical data. Several issues relating to data quality emerged. Data improvement would have likely enhanced the utility of SEM in this data set.
Development and Application of Drug Abuse Ontology for the Analysis of substances of abuse on social media and dark web (Preprint)
Authors: Lokala Usha
Published: July 2020

BACKGROUND

Web-based resources and social media platforms play an increasingly important role in health-related knowledge and experience sharing. There is a growing interest in the utilization of these novel data sources for epidemiological surveillance of substance use behaviors and trends.

OBJECTIVE

The key aims are to describe development and application of the Drug Abuse Ontology as a framework for analyzing web-based data to inform public health surveillance in the following domains: 1) user knowledge, attitudes, and behaviors related to non-medical use of buprenorphine and other illicit opioids through analysis of web forum data; 2) patterns and trends of cannabis product use in the context of evolving cannabis legalization policies in the U.S through analysis of Twitter and web forum data; and 3) trends in the availability of novel synthetic opioids through analysis of crypto market data.

METHODS

The domain and scope of the drug abuse ontology were defined using competency questions from two popular ontology methodologies (Neon and 101 ontology development methodology). The quality of the ontology is evaluated with a set of tools and best practices recognized by the Semantic Web community and the AI community that engage in natural language processing. The standard ontology metrics are also presented. The ontology was manually developed by the domain experts from the Center for Interventions, Treatment, and Addictions Research (CITAR) who used a range of data sources: 1) key epidemiological data sources and reports accessible through National Institute on Drug Abuse, Drug Enforcement Agency, European Monitoring Centre for Drugs Addiction, RxNorm and other; 2) prior peer-reviewed publications related to illicit opioids, cannabis, and other drugs; and 3) preliminary assessment and examination of web-based, social media sources related to selected substances. Sources of types 1 and 2 provided primary concepts while sources of type 3 were important in identifying alternative concepts including synonyms and street names.

RESULTS

The current version of Drug Abuse Ontology comprises 315 classes, 31 relationships, and 814 instances among the classes. The ontology is flexible and can easily accommodate new concepts. The integration of the ontology with machine learning algorithms dramatically decreases the false alarm rate by adding external knowledge to the learning process. The ontology is being updated to capture evolving concepts and has been used for three different projects: PREDOSE, eDrugTrends, and eDarkTrends.

CONCLUSIONS

It is found that the developed DAO is useful to identify the most frequently used terms/slang terms on social media/dark web related to drug abuse posted by the general population on social media and vendors on the dark web.
Cross-tier Web Programming for Curated Databases: a Case Study
Authors: Fowler Simon , Harding Simon , Sharman Joanna , Cheney James
Published: July 2020

Curated databases have become important sources of information across several scientific disciplines, and as the result of manual work of experts, often become important reference works. Features such as provenance tracking, archiving, and data citation are widely regarded as important features for the curated databases, but implementing such features is challenging, and small database projects often lack the resources to do so.
A scientific database application is not just the relational database itself, but also an ecosystem of web applications to display the data, and applications which allow data curation. Supporting advanced curation features requires changing all of these components, and there is currently no way to provide such capabilities in a reusable way.
Cross-tier programming languages have been proposed to simplify the creation of web applications, where developers can write an application in a single, uniform language. Consequently, database queries and updates can be written in the same language as the rest of the program, and at least in principle, it should be possible to provide curation features reusably via program transformations. As a first step towards this goal, it is important to establish that realistic curated databases can be implemented in a cross-tier programming language.
In this paper, we describe such a case study: reimplementing the web front end of a real world scientific database, the IUPHAR/BPS Guide to Pharmacology (GtoPdb), in the Links cross-tier programming language. We show how programming language features such as language-integrated query simplify the development process, and rule out common errors. Through a comparative performance evaluation, we show that the Links implementation performs fewer database queries, while the time needed to handle the queries is comparable to the Java version. Furthermore, while there is some overhead to using Links because of its comparative immaturity compared to Java, the Links version is usable as a proof-of-concept case study of cross-tier programming for curated databases.

Desafiando o governador: a trajetória de um soldado e os conflitos políticos entre a elite açucareira e os agentes régios em Pernambuco na segunda metade do século XVIII
Authors: Silva Giovane Albino , Silva Kalina Vanderlei
Published: July 2020

O presente artigo examina os conflitos em torno de uma enriquecida família de comerciantes da elite açucareira, os Coelho da Silva, e os agentes régios na Capitania de Pernambuco durante as últimas décadas do século XVIII. O estudo de caso de Manoel Coelho da Silva, protagonista do texto, serve como fio condutor para temas como o recrutamento militar, os laços de solidariedade e redes de proteção, a falsificação de ordenamentos religiosos e as intrigas movidas por membros das elites no cotidiano colonial. Envolvido em diversas contendas, Manoel Coelho desafiou as normas portuguesas, contrariou as leis das esferas militar, civil e eclesiástica, tornando-se fugitivo do exército e padre acusado de adquirir falsas ordenações, episódios que colocaram sua família em conflito direto com o governador e o bispo da capitania.
Quando a explicação do divino denuncia os atos humanos: o mistério do incêndio da Igreja de Nossa Senhora do Rosário dos Homens Pretos. Freguesia de São Miguel das Alagoas, 1801.
Authors: Machado Alex Rolim
Published: July 2020

Em 1801, um livro foi escrito em São Miguel das Alagoas. O assunto: a destruição da Igreja que servia de Matriz na freguesia. No intuito de explicar o ocorrido, o autor do livro atribui às ações divinas a responsabilidade de incendiar o prédio religioso. A motivação não poderia ser outra: castigo pelas ações dos homens terrenos. No entanto, os diálogos, rituais e explicações para tal catástrofe, dão pistas de que o ato fora o menos espontâneo possível. A partir da análise do contexto das relações sociais entre os grupos de São Miguel das Alagoas, pretende-se decifrar parte do mistério do incêndio e o que fundamentou o mesmo.
“Alardeiam de muita proteção para leva-los a justiça”: Agências de mulheres negras, escravidão, justiça e direitos (segunda metade do século XIX)
Authors: Moreira Paulo Roberto Staudt
Published: July 2020

O artigo analisa alguns casos (dentre os muitos encontrados) de mulheres negras incitando os funcionários do judiciário (e também da polícia) a seu favor. Investigaremos essas ações femininas negras através de documentos judiciários de reduzidas dimensões, gerados por conflitos envolvendo vizinhanças. Daremos ênfase às agências de mulheres negras já forras, protagonistas de demandas por respeito e reconhecimento social, já que esse segmento ainda carece de pesquisas a respeito. Com isso perceberemos a formação de solidariedades étnicas, mas também de como essas mulheres investiam em relações sociais plurirraciais, não sendo em absoluto possível caracterizá-las pela anomia social, muito menos pela marginalidade. Servindo-se das margens do aparelho judiciário para sua proteção, essas mulheres negras forras justificavam serem merecedoras do amparo estatal por sua pobreza (às vezes questionada, como veremos) e pela consideração social a respeito de serem trabalhadoras e gozarem da simpatia da vizinhança.

Published: July 2020

Este estudo baseia-se na análise das construções acerca do Sertão e sertanejo sobre diferentes registros históricos e por meio das vozes dos moradores do Distrito Irrigado de Maniçoba-DIM. Na metodologia foi desenvolvido um estudo qualitativo, baseado na perspectiva fenomenológica. A estratégia de pesquisa para este estudo é o da História Oral (HO). Os relatos demonstraram que os sertanejos de Maniçoba percebem a presença de preconceitos quando se trata do Sertão e do sertanejo, o que demonstra que o Nordeste construído no século XX continua sendo visto de acordo com os interesses das classes dominantes.
Viagens, sertão e sertanejos do antigo extremo norte goiano nas representações de um missionário católico na década de 1950: Quinto Tonini e seus relatos de memória
Authors: Da Silva Raylinn Barros
Published: July 2020

O objetivo deste estudo é analisar as representações de Quinto Tonini, missionário orionita italiano que viajou pelo antigo extremo norte de Goiás, década de 1950. Este estudo é resultado de uma pesquisa bibliográfica, o livro Entre Diamantes e Cristais. A hipótese é que Tonini empreendeu um esforço de memória para que ele próprio e seus missionários fossem lembrados como os desbravadores daquele sertão. A metodologia consistiu na análise da obra a partir de conceitos como desobrigas, sertão e sertanejos, interpretados a partir de estudos no campo da história cultural. A justificativa consiste na necessidade de historicizar essas memórias, o que contribui para a compreensão de parte da história religiosa da região.
Agonia e morte da Liga Comunista Internacionalista: combates finais
Authors: Campos Alzira Lobo de Arruda , Gomes Álvaro Cardoso , Godoy Marília Gomes Ghizzi
Published: July 2020

A Oposição de Esquerda em São Paulo concentrou-se em um grupo pequeno e aguerrido de camaradas, disposto a assumir a vanguarda do Partido Comunista do Brasil, denunciando a traição dos princípios marxistas-leninistas por Stálin e pela Terceira Internacional. Esse grupo, formado por trotskistas, denunciou os crimes de Stálin contra a teoria marxista-leninista e a Revolução Proletária, procurando assumir a vanguarda da revolução considerada como inevitável.  Este artigo, visando a contribuir com os estudos sobre a Revolução Russa de 1917, trata da agonia e da morte desse grupo, pouco presente nas obras historiográficas produzidas por autores que se declaram, muitas vezes, comunistas, razão pela qual resolveram excluir de seus estudos os dissidentes.

Authors: Faustino Rosangela Celia , Viceli Luciana Helena de Oliveira
Published: July 2020

O ensino de História no Brasil, na vertente tradicional, foi realizado por um viés eurocêntrico, no qual se negou aos povos indígenas o protagonismo histórico. Para justificar a ocupação dos territórios indígenas, estas populações foram colocadas, pela empresa colonizadora, como pueris, subordinadas à instrução ocidental, a disciplinarização para o trabalho. O artigo apresenta uma reflexão sobre o ensino de história e o ensino de história indígena, especialmente em escolas não indígenas. Objetiva discutir sobre a relevância do diálogo entre escola indígena e  escola não indígena, pontuando possíveis contribuições deste no aprofundamento de um debate crítico em torno da construção da interculturalidade.
Semiótica e tradução:
Authors: Fanaya Patricia Fonseca
Published: July 2020

Os estudos da tradução estiveram, por muito tempo, umbilicalmente ligados ao campo dos estudos linguísticos. Nessa relação, na qual se privilegia o signo linguístico como o mais importante dentre todos os outros e se objetiva as transferências de significados entre línguas naturais, percebe-se uma limitação teórica que torna muito difícil lidar com o processo tradutório em meio a contextos sígnicos mais amplos - especialmente se considerarmos a complexificação e o intricamento dos sistemas simbólicos ocorridos nas duas últimas décadas, promovido não só pela globalização econômica e social, mas principalmente pelos avanços tecnológicos e da inteligência artificial. O objetivo deste artigo é dar início a uma discussão renovada sobre o processo de tradução, baseada em seu encontro com a semiótica de Yuri Lotman, iluminada pela interpretação peirceana da biossemiótica de Jesper Hoffmeyer e dos expoentes da Escola de Tartu, Kotov e Kull.

Observing land-use/land-cover dynamics in semi-arid environment: Evidence from Damaturu Town and its surrounding lands, Yobe State, Nigeria
Authors: Babagana-Kyari Modibbo , Boso Babagana
Published: July 2020

The fragile Sudano-Sahelian ecological zone of Nigeria has been classified as a hotspot of land cover change (LCC) that has been suffering from serious anthropogenic and biophysical stresses. Damaturu, being the fastest growing town situated in the region happened to be a victim of this negative development. The purpose of this study is to remotely observe and assess the prevailing land-use/land-cover (LULC) dynamics of Damaturu town and its delicate surrounding lands from the year 1987-2017 study periods. To achieve this, a supervised image classification technique with Maximum Likelihood Classifier (MLC) algorithm was used in ERDAS Imagine version 15 software to classify the three epochs multi-temporal and multi-spectral Landsat imageries (TM 1987, ETM+7 2000 and OLI 2017). The classified LULC maps and their resulting statistics were then used to assess the spatio-temporal aspects of the observed changes by placing the results within the wider context of previous related literature and evidences. Findings revealed that the built-up area has been expanding since 1987 with an annual change rate of 4.5% between 1987-2000, and 5.3% during 2000-2017 respectively. The growth of the town is being accompanied by massive farmlands expansion and vegetal cover (trees and shrubs) lost making the surrounding arable lands seriously disturbed. Thus, if the observed trends continue, the entire studied region will be subjected to severe environmental hazard such as desertification. Overall, the study provides valuable information required for sustainable  environmental management.

Published: July 2020

A new approach to the protection against infections caused by bacteria and
various viruses, including SARS-CoV-2 is described. In concrete example,
protective filters and ALBO nanosilver masks showed extraordinary efficiency
in protection against Staphylococcus aureus. These results show that it
highly overcomes the efficiency of ordinary surgical masks. Besides,
systematic meta-analysis given for ordinary surgical masks and filters N95
for masks and respirators, showed no statistical difference between them in
the case of SARS-CoV-2. On the base our experimental data and systemic
meta-analysis given in this paper, it can be concluded that ALBO nanosilver
masks have significant advantages, and show a very perspective concept of
developing new protective gear.

Modeling and Optimization on the Carbon Dioxide Separation from Natural Gas Using Hydrotalcite-Silica Membrane
Authors: Daham Wiheeb Ahmed
Published: July 2020

The process modeling and optimization of carbon dioxide (CO2) separation from carbon dioxide-methane (CH4) binary gas mixture through hydrotalcite (HT)-silica membrane using statistical design of experiments (DoE) is reported in this study. The effect of three important process variables, pressure difference across the membrane (100-500 kPa), temperature (30-190oC) and CO2 feed concentration (10-50%) on the CO2 separation performance of the membrane were investigated. The response surface methodology (RSM) coupled with central composite design (CCD) was used to build up two models to correlate the effect of process conditions to CO2 permeance and CO2/CH4 separation selectivity. The analysis of variance (ANOVA) of the quadratic model at 95% conﬁdence interval confirmed that the model was highly signiﬁcant. The CO2 feed concentration with 43% showed the best performance with a CO2 permeance of 6.0x10-7 mol.m-2.s-1.Pa-1 and a CO2/CH4 separation selectivity of 109 at 100 kPa pressure difference across the membrane and temperature of 30oC
Surge Tank Analysis for Water Hammer Remedy for Long Distance Pipeline
Authors: J. Rasheed Nisreen
Published: July 2020

Various protection methods can be used for protecting the pipeline system from the impact of water hammer. Which includes the use of special materials for supporting the pipeline and the installation of special devices such as surge tanks, relief valves, and air chambers. In this study, to protect the pipeline system and reduce the effect of water hammer, surge tank has been used. Governing equations of transient flow with and without surge tank is numerically simulated using MATLAB software. Sensitivity analysis was investigated using several variables such as pipe diameter, wave’s velocity and friction factor. Method of characteristics (MOC) was implemented in this study. It was found that the diameter and friction factor of pipe have a significant impact on the results of transient flow and surge tank compared to the effect of wave’s velocity. It has been reached that the capacities of surge tanks at diameter (1m), are (1475m3) at first, second and fourth stages, (1360m3) at third and fifth stages and (570m3) at sixth stage. And at diameter (1.2m), the capacities are (1700m3), (1530m3) and (1475m3) at first, second and third stages respectively. But at diameter (1.4m), the capacities are (1590m3) at first and second stages. For all values of wave’s velocity, the capacities of surge tanks are (1760m3), (1530m3) and (1420m3) at first, second and third stages respectively. But the capacities of surge tanks at friction factor (0.007) are (1810m3), (1585m3) and (1245m3) at first, second and third stages respectively. However, for the capacity of surge tanks at the friction factor (0.008), it was mentioned when the surge tanks capacity of the diameter (1.2m) was mentioned. And when the friction factor is (0.009), the capacities are (1460m3) at first stage, (1415m3) at second and third stages and (570m3) at fourth stage

Analyzing Political Marketing in Indonesia: A Palm Oil Digital Campaign Case Study
Authors: Khairiza Fajrina , Kusumasari Bevaola
Published: July 2020

Social media in political marketing is an emerging area of research. This study explains how social networks are constructed in a digital campaign, identifying key actors, and messages involved in modern political marketing. A hotly contested palm oil campaign in Indonesia serves as a case study to analyze and visualize the messaging content found in digital campaigns. Social Network Analysis (SNA) was used to map the social network sites in Twitter and to track social interaction patterns in the #SawitBaik campaign. The results confirmed that state institutions, non-governmental institutions, news media, and individuals were key actors in the digital campaign. The actors’ roles varied from providing information and supporting palm oil activities to criticizing palm oil activities and promoting campaign events. Most tweets were critical of the government, serving as brand advocacy. The #SawitBaik campaign is also an example of political marketing used by a government in order to influence its citizens. In this case, the goal was to shape and win public support by legitimizing palm oil activities in Indonesia.

Published: July 2020

Aims

Exhaled breath contains thousands of volatile organic compounds (VOCs) produced during various metabolic processes both in health and disease.

Analysis of breath with electronic nose BIONOTE-V allows modifications of exhaled VOCs to be studied, which are clinically recognized to be a marker for several disorders, including heart failure. New noninvasive tests based on VOCs analysis might be a useful tool for early detection of chronic coronary syndromes (CCS).

Methods

Exhaled air was collected and measured in individuals with an indication to perform invasive coronary angiography (ICA). All patients’ samples were obtained before ICA.

Results

Analysis with BIONOTE-V was performed in a total cohort of 42 patients consecutively enrolled, of whom 19 did not require myocardial revascularization and 23 with indication for myocardial revascularization. BIONOTE-V was able to correctly identify 18 out of 23 patients affected by severe coronary artery disease (sensitivity = 78.3% and specificity = 68.4%). Our predicted model had a tight correlation with SYNTAX score (error of the BIONOTE-V = 15).

Conclusion

CCS patients have a distinctive fingerprint of exhaled breath, and analysis by BIONOTE-V has the potential for identifying these patients. Moreover, it seems that this technique can correctly identify patients according to anatomical disease severity at ICA. If the preliminary data of this proof of concept study will be confirmed, this rapid and noninvasive diagnostic tool able to identify CCS might have an impact in routine clinical practice.

Published: July 2020

Aim

Adherence to guidelines was not homogeneous in Europe, according to the survey on cardiac resynchronization therapy conducted in 2008–2009. The aim of our study was to compare the results in the Italian and European cohorts of the Second European Cardiac Resynchronization Therapy Survey.

Methods

Patients’ characteristics, procedural data and follow-up were collected. Italian records were compared with European countries.

Results

Italian hospitals enrolled 526 patients. The italian cohort was older (71.6 ± 9.5 vs. 68.4 ± 10.8; P < 0.00001), had less severe NYHA class (>II 47.2 vs. 59.6%; P < 0.00001), higher ejection fraction (30.3 ± 7.4 vs. 28.4 ± 8.2%; P < 0.00001), and less atrial fibrillation prevalence (34.4 vs. 41.2%; P = 0.00197) than the European cohort. Italian patients were more frequently hospitalized for heart failure in the previous year (51.9 vs. 46.2%; P = 0.01118) and had lower mean QRS duration (151 ± 26 vs. 157 ± 27 ms; P < 0.0001). CRT-D were more often implanted in Italian patients (79.3 vs. 69.3%; P < 0.00001). The complication rate was similar (4.6% vs. 5.6%; ns). The rate of use of ACEi/ARBs in Italy was lower than in Europe (77.2 vs. 86.9%; P < 0.00001). Patients were followed up in the implantation centre (92.1 vs. 86%; P = 0.00014), but rarely with remote monitoring (25.9 vs. 30%; P = 0.04792).

Conclusion

The survey demonstrates important similarities as well as substantial differences regarding most of the aspects evaluated. Efforts to implement adherence to guidelines will be endorsed in Italy.

ACE2 receptor has a broad expression pattern in the cellular membrane and provides a protective action against the development of cardiovascular diseases. Recently, this enzyme has become of extreme interest during the pandemic infection of COVID-19 (coronavirus disease 2019). This virus invades alveolar epithelium and cardiomyocytes using ACE2 as a transmembrane receptor. ACE2 is a counter-regulatory peptide that degrades Ang II into Ang 1–7, thereby attenuating the biological effects of the AT1 receptor. The binding between the spike protein of COVID-19 and the enzyme is crucial for the virus to enter the target cells, but whether an increase in ACE2 activity could facilitate the infection is not yet demonstrated. However, this aspect has raised many concerns about the use of ACE inhibitors or ARBs in infected patients or patients at risk of infection. It appears that cellular infection leads to a reduction in ACE2 expression and an increase in the activity of the Ang II--AT1 axis, which leads to the release of pro-inflammatory cytokines, ARDS, myocarditis, and hypercoagulability with the possibility of exacerbation of acute coronary syndrome, induction of pulmonary embolism, or appearance of disseminated intravascular coagulation. Therefore, ACE inhibitors or angiotensin receptor blocker drugs should be continued in infected patients, as their discontinuation can increase Ang II activity and induce injury to the lungs or cardiovascular system.

Let  be a metric space and  be a continuous map. The notion of the  -average shadowing property ( ASP )  for a continuous map on  â€“space is introduced  and the relation between the ASP and average shadowing property(ASP)is investigated. We show that if  has ASP, then   has ASP for every . We prove that if a map  be pseudo-equivariant with dense set of periodic points and has the ASP,  then  is weakly mixing. We also show that if   is a expansive pseudo-equivariant homeomorphism that has the ASP and  is topologically mixing,  then  has a  -specification. We obtained that the identity map  on  has the ASP  if and only if the orbit space  of  is totally disconnected. Finally, we show that if  is a pseudo-equivariant map, and  the trajectory  map  is a covering map, then  has the ASP  if and only if the induced map   has ASP.

Due to the large-scale development in satellite and network communication technologies, there is a significant demand for preserving the secure storage and transmission of the data over the internet and shared network environments. New challenges appeared that are related to the protection of critical and sensitive datafrom illegal usage and unauthorized access. In this paper, we address the issues described above and develop new techniques to eliminate the associated problems. To achieve this, we propose a design of a new sensor node for tracking the location of cars and collecting all information and all visited locations by cars, followed byencryption in a sensor node and saving in the database. A microcontroller of Arduino esp8266 Node MCU board and a GPS module are used. The cryptography uses the chaos-based symmetric-key encryption technique for data. This scheme utilizes a chaotic map (HÃ©non map) for robustness and security of data. The key sensitivity can be performed by statistical experiments to determine the safety, reliability, and speed of the algorithm. The proposed algorithm presents several exciting features, such as a high level of security, sufficient saving of the energy of the sensor network, and an acceptable encryption speed compared to Advanced Encryption Standard (AES) and Data Encryption Standard (DES).

Untuk suatu graf terhubung nontrivial G, c : V (G) ! N adalah suatupewarnaan titik di G, yang mana titik-titik yang saling bertetangga dapat diwarnaidengan warna yang sama. Untuk suatu titik v 2 V (G), himpunan warna lingkunganNC(v) adalah himpunan yang berisikan warna dari lingkungan v. Pewarnaan c dise-but suatu himpunan pewarnaan jika NC(u) 6= NC(v) untuk setiap pasangan titik u; vyang bertetangga di G. Bilangan minimum dari warna-warna yang dibutuhkan dari su-atu pewarnaan c disebut bilangan kromatik himpunan s(G). Pada makalah ini akandikaji kembali bahwa setiap graf k-colorability himpunan merupakan suatu masalah NP-complete dengan suatu transformasi kedalam k-colorability, sehingga bilangan kromatikhimpunan s dapat ditentukan dalam waktu polinomial. Dari ketiga kelas graf sempurnayang digunakan dalam tulisan ini, yaitu graf chordal, graf split, dan graf threshold, hanyagraf threshold yang bilangan kromatiknya bernilai sama dengan bilangan kromatik him-punannya. Selanjutnya pada tulisan ini juga telah ditunjukkan bahwa, jika G adalahgraf threshold, maka bilangan kromatik himpunan s(G) dapat dihitung secara esiendalam waktu polinomial.
