Authors: Ramses  , Fenny Agustina  , R. Pramuanggit Panggih Nugroho
Published: June 2021

Background: Vibriosis is currently still a major problem in marine aquaculture and is highly dependent on availability of antibacterial agents in its handling. Investigation of antibacterial potential of the coastal plants of Bidara Laut (Ximenia americana) has been carried out. Methods:  Parts of the X. americana plant taken are Old Fruit, Young Fruit, Old Leaf, and Young Leaf. A total of ± 200 grams of each part of X. americana plant was taken to be extracted using maceration method. The antibacterial activity test was performed using the Kirby-Bauer disc diffusion method on Muller Hinton Agar (MHA) media. Observations were made in time units, namely every 6 hours of incubation for 24 hours. Results: The tested extract of plant parts of X. americana showed an inhibition zone against the growth of V. alginolyticus and V. parahaemolyticus bacteria in each replication in all-time units of observation. Of the four types of extracts tested, old leaves showed strong category resistance to V. alginolyticus with the highest clear zone diameter of 16 mm (average 14.67 mm) at 6 hours incubation. Young leaves gave the highest of 18 mm (average 16.33 mm) against V. parahaemolyticus at 6 hours incubation. Conclusions: X. americana plants have potential for antibacterial against Vibriosis disease in aquaculture. The ability of power to be seen tended to decrease for all tests until the end of observation, but until the end of observation, the ability of extract inhibition of all parts of the plant was still in the moderate to strong category.

Robust Lag Weighted Lasso for Time Series Model
Authors: Dikheel Tahir R. , Yaseen Alaa Q.
Published: June 2021

The lag-weighted lasso was introduced to deal with lag effects when identifying the true model in time series. This method depends on weights to reflect both the coefficient size and the lag effects. However, the lag weighted lasso is not robust. To overcome this problem, we propose robust lag weighted lasso methods. Both the simulation study and the real data example show that the proposed methods outperform the other existing methods.
Experimental localisation of quantum entanglement through monitored classical mediator
Authors: Pal Soham , Batra Priya , Krisnanda Tanjung , Paterek Tomasz , Mahesh T. S.
Published: June 2021

Quantum entanglement is a form of correlation between quantum particles that cannot be increased via local operations and classical communication. It has therefore been proposed that an increment of quantum entanglement between probes that are interacting solely via a mediator implies non-classicality of the mediator. Indeed, under certain assumptions regarding the initial state, entanglement gain between the probes indicates quantum coherence in the mediator. Going beyond such assumptions, there exist other initial states which produce entanglement between the probes via only local interactions with a classical mediator. In this process the initial entanglement between any probe and the rest of the system "flows through" the classical mediator and gets localised between the probes. Here we theoretically characterise maximal entanglement gain via classical mediator and experimentally demonstrate, using liquid-state NMR spectroscopy, the optimal growth of quantum correlations between two nuclear spin qubits interacting through a mediator qubit in a classical state. We additionally monitor, i.e., dephase, the mediator in order to emphasise its classical character. Our results indicate the necessity of verifying features of the initial state if entanglement gain between the probes is used as a figure of merit for witnessing non-classical mediator. Such methods were proposed to have exemplary applications in quantum optomechanics, quantum biology and quantum gravity.
Comparación de algoritmos de resumen de texto para el procesamiento de editoriales y noticias en español
Authors: López-Trujillo Sebastián , Torres-Madroñero María C.
Published: June 2021

El lenguaje se ve afectado, no solo por las reglas gramaticales, sino también por el contexto y las diversidades socioculturales, por lo cual, el resumen automático de textos (un área de interés en el procesamiento de lenguaje natural - PLN), enfrenta desafíos como la identificación de fragmentos importantes según el contexto y el tipo de texto analizado. Trabajos anteriores describen diferentes métodos de resúmenes automáticos, sin embargo, no existen estudios sobre su efectividad en contextos específicos y tampoco en textos en español. En este artículo se presenta la comparación de tres algoritmos de resumen automático usando noticias y editoriales en español. Los tres algoritmos son métodos extractivos que buscan estimar la importancia de una frase o palabra a partir de métricas de similitud o frecuencia de palabras. Para esto se construyó una base de datos de documentos donde se incluyeron 33 editoriales y 27 noticias, obteniéndose un resumen manual para cada texto. La comparación de los algoritmos se realizó cuantitativamente, empleando la métrica Recall-Oriented Understudy for Gisting Evaluation. Asimismo, se analizó el potencial de los algoritmos seleccionados para identificar los componentes principales del texto. En el caso de las editoriales, el resumen automático debía incluir un problema y la opinión del autor, mientras que, en las noticias, el resumen debía describir las características temporales y espaciales de un suceso. En términos de porcentaje de reducción de palabras y precisión, el método que permite obtener los mejores resultados, tanto para noticias como para editoriales, es el basado en la matriz de similitud. Este método permite reducir en un 70 % los textos, tanto editoriales como noticiosos. No obstante, es necesario incluir la semántica y el contexto en los algoritmos para mejorar su desempeño en cuanto a precisión y sensibilidad.
Sistema de gestión de energía descentralizado basado en multiagentes para operación de múltiples microrredes
Authors: Sánchez Silvera Alfredo , Guarnizo-Marín José Guillermo , Forero-García Edwin Francisco , Montenegro-Martínez Davis
Published: June 2021

En años recientes, las microrredes han logrado un considerable desarrollo debido a que representan una alternativa técnica para responder a contingencias en la red de distribución, como también a incrementar el nivel de generación distribuida, entre otros beneficios. Por tal motivo, el presente artículo presenta un modelo de gestión energética basado en sistemas multiagentes para microrredes que operan en modo isla. El objetivo de esta investigación es el diseño de un sistema multiagente que permita gestionar el funcionamiento de un conjunto de microrredes distribuidas en un entorno aislado, además de mantener la correcta conexión con el bus común que une todas las microrredes, el sistema multiagente debe evitar sobrecargas y descargas profundas en las baterías. La metodología implementada es de tipo empírico analítica, la simulación comienza con una revisión del estado del arte, en búsqueda de una estrategia que permita coordinar un sistema de microrredes compuesto, donde estas están conectadas al mismo sistema de distribución operando en modo isla. La simulación del sistema se realizó mediante OpenDSS-G y Python. Los resultados obtenidos sugieren que un sistema de gestión de energía descentralizado, basado en la teoría de sistemas de agentes múltiples, puede tener importantes beneficios como, por ejemplo, el carácter autónomo de las microrredes para la generación de energía en zonas no interconectadas. Finalmente, con la teoría de multiagente se pueden crear sistemas de generación distribuida más confiables debido a su capacidad autónoma de toma de decisiones, para cubrir demandas eléctricas desde microrredes vecinas y conjuntamente prevenir sobrecargas y profundas descargas en las baterías.
Avowing Unemployment: Confessional Jobseeker Interviews and Professional CVs
Authors: Boland Tom
Published: June 2021

While contemporary welfare processes have widely been analysed through the concepts of governmentality and pastoral power, this article diagnoses the dimension of confession or avowal within unemployment, job seeking and CV writing. This argument draws together the threads of Foucault’s work on confession within disciplinary institutions, around sexuality and genealogies of monasticism, adding the insights of writers in ‘economic theology’. Empirically the focus is on UK JobCentrePlus, whose governmentality is traced from laws and regulations, street-level forms, websites and CV advice. From the requirement of avowals of unemployment as a personal fault in interviews to professions of faith in oneself and the labour market, a distinctly confessional practice emerges – with the welfare officer as ‘pastor’ but with the market as the ultimate ‘test’ of worth. Furthermore, the pressure to transform the self through ‘telling the truth’ about oneself is taken as a normalising pressure which extends from the institutions of welfare across the labour market as a whole. In conclusion, the demand for self-transformation and the insistence on tests within modernity is problematised.
The Carnival of the Mad: Foucault’s Window into the Origin of Psychology
Authors: Venable Hannah Lyn
Published: June 2021

Foucault’s participation in the 1954 carnival of the mad at an asylum in Switzerland marked the beginning of his critical reflections on the origins of psychology. The event revealed a paradox at the heart of psychology to Foucault, for here was an asylum known for its progressive method and groundbreaking scientific research that was somehow still exhibiting traces of a medieval conception of madness. Using the cultural expression of this carnival as a starting place, this paper goes beyond carnival costumes to uncover the historical structures underneath the discipline of modern psychology. Drawing on Foucault’s earliest works in psychology, his 1954 Mental Illness and Personality, his 1954 “Dream, Existence and Imagination,” his 1957 “Scientific Research and Psychology” and briefly his 1961 History of Madness, I will describe the discrepancy between the theory of modern psychology, which finds its heritage in the methods of modern science, and the practice of modern psychology, which finds its heritage in the classical age. I will argue that this division helps make sense of unexplained psychological phenomena, as seen in general practices related to artistic expression, and individual experiences, as seen in the presence of guilt and the resistance to medical diagnosis in patients.
Resistance: An Arendtian Reading of Solidarity and Friendship in Foucault
Authors: Schoonheim Liesbeth
Published: June 2021

Recent scholarship has firmly established the similarities between Arendt and Foucault, in particular with regard to the dangers of late-modern social processes. Yet, few have compared their accounts of resistance. This paper argues that although Foucault offers the more comprehensive account, it omits the encounter with the other as unique and unfathomable, which is central to Arendt’s. This omission is particularly striking given the authors’ shared belief that the danger of ‘the social’ and ‘governmentality’ lies in atomizing individuals and barring the development of a singular style of being, and their allusion to friendship and solidarity as sites of resistance.

Drawing on Arendt, I show how Foucault restricts his thematization of solidarity and friendship to a reflexive praxis of the subject on her own limits, and argue instead for the relational dimension of resistance. I start by reconstructing their converging analysis of biological racism. I then continue with a discussion of resistance in Arendt, which she develops in response to the Shoah. More specifically, she provides a concept of solidarity and friendship that I draw on to extend Foucault’s analysis of the transnational solidarity among the governed in fighting for their rights vis-à-vis their governments; and of friendship in the context of his interrogation of the LGBT-movement.

Desenvolvimento de um Ambiente Computacional para a Programação, Geração de Movimentos e a Análise Cinemática de um Robô Didático
Authors: Ramirez Rafael Garcia , Zem Paulo Fernando , Decol Gustavo Copini
Published: June 2021

O Laboratório de Automação e Robótica da universidade possui um kit robótico denominado Robix, formado por um corpo robótico montável, uma unidade controladora e um software de programação chamado Rascal. O software permite a programação dos movimentos, mas apresenta limitações, pois a geração de trajetórias e a análise cinemática não são recursos com os quais o acadêmico consiga interagir de forma didática. Assim, desenvolveu-se um ambiente computacional, usando o Matlab, para a programação, geração de trajetórias e a análise cinemática. A interface gráfica desenvolvida visou a aplicabilidade dos cálculos cinemáticos e de trajetórias, sendo possível modificar e aperfeiçoar os algoritmos pelos acadêmicos. Também, de modo a tornar a solução independente da unidade de controle e visando à flexibilização da conexão com o computador, foi implementada uma interface via USB, que interage com a plataforma Arduino MEGA. Os algoritmos e recursos foram testados com resultados satisfatórios.
Farmers' mental models of soil fertility in a semi-arid area of Kenya
Authors: Yageta Yoshie , Osbahr H , Morimoto Yasuyuki , Clark Joanna
Published: June 2021

Effective knowledge exchange between farmers and other stakeholders,
such as agricultural extensionists and soil scientists, is essential for
increasing opportunities for sustainable soil fertility management. To
achieve this, it is necessary to understand local farmers’
conceptualisation of soil fertility. This study visualizes farmers’
perceptions of soil fertility as mental models, in order to explore the
expansion of their soil knowledge and the extent of their comprehension
of the relationship between soil properties that are seen and measured
and soil processes. Aggregated mental models of fertile and low
fertility soils were created from data collected from 59 farmer
interviews at two villages in Kitui County, Kenya. The share of
respondents of each concept were shown to analyse the knowledge gaps
among farmers and between villages. The mental models revealed that
farmers recognize the important roles of soil texture, water
availability and farm management in soil fertility. Their knowledge
related to their lived experience of the actual productivity of soils,
which resulted in a strongly different perspective of fertile and low
fertility soil. The differences of perception between the villages were
also recognized as the result of differences in land availability.
Although the farmers who mentioned soil processes were very few, farmers
had the potential to integrate further soil scientific knowledge.
Consequently, using the mental model approach to visualize farmers’
perceptions produced benefits by clarifying understanding of farmers’
knowledge and identifying gaps where soil science and extension work
could help to expand farmers’ knowledge.
Impact of a reduced palonosetron maximum dose on the incidence of chemotherapy-induced nausea and vomiting in pediatric patients
Authors: Kramer Liza , Trinkman Heidi , Arrowood Robert , Ray Anish
Published: June 2021

Background Palonosetron is a serotonin-3 (5-HT3) receptor antagonist
indicated in the prevention of chemotherapy-induced nausea and vomiting
(CINV) in pediatric and adult patients. Traditional dosing for
palonosetron in the pediatric population has been 20 mcg/kg with a
maximum dose of 1500 mcg. This study aimed to evaluate the impact of an
institutional dose cap of 750 mcg on pediatric CINV. Procedure This is a
retrospective chart review of admitted patients given palonosetron
intended for prevention of CINV at a pediatric medical center between
July 1, 2018 and June 30, 2020. Patients 1 month up to 17 years of age
who received at least one dose of palonosetron prior to chemotherapy
(not preceding stem cell transplant) were included. Information
regarding chemotherapy, antiemetic premedication, emesis, and
breakthrough antiemetic agents were recorded to quantify the instances
of CINV. Results Seven hundred and seventy-one patient encounters met
inclusion criteria (n=485 traditional dose, n=286 dose capped). There
was no statistical difference in the instances of emesis (p=0.98) or
breakthrough agents administered (p=0.65) between the two groups. Dose
capping patients at 750 mcg reduced cost by approximately 34.9%
compared to traditional dosing. Conclusions The use of a dose cap of
palonosetron at 750 mcg maintains efficacy for prevention of CINV while
reducing cost in pediatric patients receiving chemotherapy.

Authors: Muttoni Magdalena , De Almeida Facundo
Published: June 2021

El Stand Interactivo “En busca del pasado” es un juego interactivo de arqueología que, mediante la recreación de los escenarios típicos del proceso de investigación arqueológica -excavación, laboratorio y museo- y la utilización de una aplicación de Realidad Aumentada donde pueden observarse objetos originales en 3D, permite a los participantes simular el trabajo del arqueólogo, en una propuesta divertida y didáctica. Su objetivo es difundir las distintas etapas de investigación arqueológica: el espacio de excavación arqueológica, el espacio de análisis de las piezas (laboratorio) y el espacio de exhibición y socialización de los contenidos investigados y elaborados. Los visitantes (niños, jóvenes y adultos) pueden transitar e interactuar con los distintos escenarios a través del uso de la tecnología de realidad aumentada y de propuestas didácticas, que estimulan la comprensión de las formas de investigación arqueológica, y por ende del pasado indígena y comprender la necesidad de respetar los sitios arqueológicos reales.

Published: June 2021

Batarya dengeleme sistemleri batarya hücrelerinin dengeli şarj ve deşarjı için gereklidir. Batarya paketlerinin ömrü, verimliliği ve güvenliği dengeleme sistemleri ile artırılabilir. Batarya dengeleme sistemleri pasif ve aktif olarak ikiye ayrılır. Pasif dengeleme sistemlerinde, hücreler arasında dengesizliğe neden olan yük miktarı bir dirençle boşaltılırken, aktif dengeleme sistemlerinde hücreler arası dengesizlik, enerjinin yüksek şarjlı hücreden düşük olana aktarılmasıyla ortadan kaldırılır. Artan hücre sayısı, dengeleme sistemlerinin karmaşıklığına yol açmaktadır. Dönüştürücü tabanlı dengeleme sistemleri, çok sayıda hücreye sahip batarya paketleri için uygun bir çözüm sunar. Bu çalışmada, batarya aktif dengeleme sistemlerinde kullanılmak üzere çift yönlü bir flyback dönüştürücü geliştirilmiştir. Simülasyon ve test sonuçları, geliştirilen çift yönlü flyback dönüştürücünün batarya aktif dengeleme sistemleri için uygun olduğunu ortaya koymuştur. Hücre şarj yönü testinde en yüksek verim %32,5 görev döngüsünde %67,84 olarak ve hücre deşarj yönü testinde %50 görev döngüsünde %66,02 olarak elde edilmiştir.
A study of QCD at finite density using complex Langevin dynamics
Authors:   ,   Swansea University, Attanasio Felipe
Published: June 2021

Numerical simulations are a standard tool to investigate field theories in non-perturbative regimes. Typical algorithms used to evaluate path integrals in Euclidean space rely on importance sampling methods; i.e., a probabilistic interpretation of the Boltzmann weight eS. However, many theories of interest suffer from the infamous sign problem: the action is complex and the Boltzmann weight cannot be used as a probability distribution. Complex Langevin simulations allow numerical studies of theories that exhibit the sign problem, such as QCD at finite density. In this thesis, we study methods to investigate the phase diagram of QCD in the temperature{chemical potential plane, using the complex Langevin method. We provide results on the phase diagram for the heavy-denseapproximation of QCD (HDQCD) for three spatial volumes, using complex Langevin and the gauge cooling technique. We also present polynomial fits of the critical temperature as function of the chemical potential for each volume. Subsequently, we discuss instabilities encountered during this study, which motivated a novel technique, named Dynamic Stabilisation, which will be introduced and the theoretical ideas behind it, explained. Dynamic stabilisation was, then, used in an investigation of the dependency of the critical chemical potential on the hopping parameter. The two previous studies were used to guide a second examination of the HDQCD phase diagram, focussed around the phase boundary. Lastly, we present preliminary results on the phase diagram of QCD with fully dynamical quarks at high temperatures. This shows that complex Langevin, augmented with gauge cooling and dynamic stabilisation, is suited for investigating QCD at finite chemical potential.

The formation of the management system for economic formations needs updating due to the fact that the increase in the volume of analyzed information, the rate of its appearance and loss of significance, as well as digitalization in the economy and socio-economic life are outdated in our time. One of the most important tasks for the productive and successful management of economic formations is precisely to obtain reliable, complete and timely information about business processes. This article demonstrates that for accounting and information support of management and, in general, the entire structure of management of economic formations, it is necessary to significantly reform, a qualitative transition from management using automated software and technologies to self-learning systems for processing and interpreting information about accounting objects. The knowledge system, repository, semantic network and tools that make it possible to process new precedents are the structural elements of this control system. All this has an impact on reducing the influence of the human factor, increasing the effectiveness of making managerial decisions, as well as increasing the speed of information processing.

At the end of the XX - beginning of the XXI century, there are global processes of climate change under the influence of anthropogenic factors, the preservation of these trends entail extreme and almost irreversible consequences. It is obvious that climate change affects agricultural production and its productivity throughout the world. The climate change economy is an innovative economy direction that emerged at the junction of ecology and economy and global environmental requirements are conditioned. The agriculture one of the major sources of greenhouse gas emissions, can play an important role in mitigating the effects of climate change. The principles of the economy of climate change are aimed at solving two key issues: achieving "improved growth" and achieving an "improved climate". Objectives of the review: to analyze the global processes of climate change; to study the economic impacts of climate change on agriculture in Kazakhstan; consider a system of measures to prevent global climate change in the context of the climate change economy. For review have used different literature as IPCC, WMO, WTO, FАО, UNEP, UNFCCC, UNDP, IMF, WB, ОEСD, KAZHYDROMET, IRRI, Committee of the Statistics of the Kazakhstan reports and etc.

TikTok is a recent global phenomenon and in the first quarter of 2020 alone it has TikTok been downloaded 315 million times. People love it because it allows them to spur creativity in video content and increase their online presence. Founded by a Chinese company, this social networking application has become a trend for about 400 million loyal users in China. However, studies about how people become loyal to TikTok are lacking. This study aims to examine the effect of service quality and satisfaction to loyalty of TikTok users in China. Since the study was focused in an online environment, the terms E-service quality, E-satisfaction and E-loyalty are used instead of the conventional ones. SEM-PLS was employed to analyze valid and reliable data which was successfully collected from 400 Chinese TikTok users. The result confirmed that E-service quality affects significantly and positively E-satisfaction and E-loyalty, E-satisfaction also significantly and positively affects E-loyalty and E-satisfaction mediates the relationship between E-service quality and E-loyalty. Since the TikTok application is easy to use with interesting features for its users, the company has successfully delivered information about the booming of TikTok use all over the world and impressing users so that they have high trust in the application’s ability to make them more famous and socially famous. Therefore users believe that TikTok can provide them something better than what they expected. When reality exceeds the expectation, customers will be satisfied. TikTok is also believed to have a good, reliable and available system.

Every person matters.—Tom Hanks as James Donovanin movie “Bridge of Spies” Hashtag (ie, the # symbol)1 is a type of metadata tag used in the different social media, such as Instagram, Twitter, YouTube, etc. It was invented by Chris Messina in 2007, when he proposed to use hashtag in Twitter with a purpose to group and easily find posts with a specific content/theme. Scientific journals from different specialties with high Impact Factor are also paying a great attention to the role of hashtags in their journals` media accounts lifes.1, 2The DTJournal`s first Instagram-related international collaboration started in 2017, during the 23rd International Conference on Oral and Maxillofacial Surgery in Hong Kong. Using in DTJournal`s account the hashtag #icoms2017 (which included 164 posts) two participants of the event Dr. Monteiro and Dr. Fesenko began a productive conversation dedicated to submission of a case report article.3 Which was successfully published (Fig) in the nearest issue. So, an Editorial`s message to the colleagues is very clear: Do not regret the time to use hashtags in all kind of scientific, communicative or marketing purposes.

The official cause of the coronavirus disease 2019 (Covid-19) 2 became a novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) 3 which was officially identified on January 9, 2020. 4
Generally described four transmission routes for the Covid-19: 1) aerosol transmission, 2) contact transmission, 3) droplets transmission, and even through 4) digestive system. 3 The most commonly reported symptoms in patients are cough, fever, myalgia/fatigue, pneumonia, and complicated dyspnea. 3,5 According to Li et al cases resulting in death were primarily in elderly and middle-aged patients with pre-existing co-morbidities. 6 The statistically proved number of death worldwide continues permanently to increase. On March 26 that number of death reached 21,297 people, 7 on April 1 – 42,341 people, 8 on April 7 – 74,820 people, 9 on May 29 – 362,091 10 , and on August 11 – 739,342 11.
Among many governments` measures became: closed borders, quarantine, and “stay at home” order (excluding medicine and urgent dentistry workers). A 1,000-bed United States Navy hospital ship docked in New York, 12 huge government`s emergency field hospitals open in the exhibition convention centers 13,14 around the globe. And the list of measures in different countries continues to an extent with one goal – to save more lives. Elective surgeries, except emergency and cancer cases surgeries, were also forbidden.
From the moment of closed borders, the wave of canceled scientific meetings starts to grow continually affecting the meetings industry, specialties, and continuing medical education.
Among them, two very important spring oral and maxillofacial surgery (OMS) events were canceled: A 77th Annual Meeting of the American Cleft Palate-Craniofacial Association (ACPA) in Portland (scheduled from March 31 to April 4, 2020) 15 and the 1st International Symposium on Orthognathic Surgery of the International Association of Oral and Maxillofacial Surgeons (IAOMS) in Vienna (scheduled from April 30 to May 2, 2020) 16 .
