Published: May 2021

This work proposes an implementation in Field Programmable GateArray (FPGA) of the Otsu’s method applied to real-time trackingof worms called Caenorhabditis elegans. Real-time tracking is necessaryto measure changes in the worm’s behavior in response totreatment with Ribonucleic Acid (RNA) interference. Otsu’s methodis a global thresholding algorithm used to define an optimal thresholdbetween two classes. However, this technique in real-time applicationsassociated with the processing of high-resolution videoshas a high computational cost because of the massive amount ofdata generated. Otsu’s algorithm needs to identify the worms ineach frame captured by a high-resolution camera in a real-timeanalysis of the worm’s behavior. Thus, this work proposes a highperformanceimplementation of Otsu’s algorithm in FPGA. Theresults show it was possible to achieve a speedup up to 5 timeshigher than similar works in the literature.

Published: May 2021

Given the diversity of information systems today, communicationbetween services requires that APIs be well designed and understoodby both services producers and consumers. Poorly documentedAPIs lead to misunderstandings by developers and testersteams who end up designing ineffective test cases. As a result, theymay produce software with low quality and avoidable errors. Thisstudy investigates the ability of the SigniFYIng APIs tool to supportthe testability of the applications consuming APIs. In this paper, weproposed a process to support APIs’ testability with the SigniFYIngAPIs tool. We validated the process with a real case study basedon two Brazilian federal government APIs: the leniency agreementAPI and the federal servants API. As a result, it was possible todevelop better test cases for the chosen APIs, bringing evidencethat the proposed process can support designing more suitable testcases for APIs and improving the testability of the software to beproduced.

Published: May 2021

The studies and applications of nanofibers have grown over the years. It was observed that the properties of the nanometer-scale yarns present advantages in applications in several areas, such as biomedical, energy storage and production, and applications involving water filtration. These materials are synthesized through a technical process and, for that reason, they are subject to the presentation of failures. The most common flaws are the formation of granules and pores. With the evolution of computing, applications that use machine learning resources can assist in detecting these failures. This work aims to evaluate and compare two different approaches to morphological analysis to see losses in nanofibers. Firstly, a data set was created using a Scanning Electron Microscope. After that, each image was analyzed by ImageJ software and by RNA solution. As a hypothesis, the article will assess whether the beads identification and the number of beads by the analog method are statistically similar (H0) or statistically different (H1) from the machine learning method. The preliminary results indicate that for the group that used 100 images and computer visualization, the analog method's accuracy was 7.23%. In order to accuracy increase, another test with 150 more distinct images was done, bringing a new result of 55.09%. The analysis time was considerably less when performed by the computational method. It was possible to conclude that the computational approach does not have the beads identification statistically similar to the analog way concerning the methodology used. Therefore, rejected H0. However, the directly proportional relationship of accuracy with the number of samples suggests that training with more various images can calibrate the algorithm.

Published: May 2021

BACKGROUND Globally there has been an increase in the usage of miniscrew implants (MSI) because it expanded the envelope of discrepancy which led to the management of most severe cases without surgery. There is limited data available about awareness and usage of MSI among Indian orthodontists. So, the purpose of this study was to evaluate the Indian orthodontists’ experiences regarding MSI. METHODS The study sample consisted of 1000 qualified orthodontists practicing in India. The present study was a questionnaire-based survey, circulated among the orthodontists through Google forms. The questionnaire included both close-ended and selfadministered questions. The data was analysed using the statistical analysis SPSS software version 20.0. RESULTS Out of 2000 circulated Google forms there was 50 % response rate. Among the participants, 95.7 % had attended training for MSI placement. Among the participants who attended training, 81.1 % were using mini screw in practice, of whom 60 % participants had placed more than 50 implants. Most participants (70.9 %) recommended insertion torque of 5 – 10 Nm and for the time of force application, 48.6 % go with force application immediately after placement. Most participants (75.7 %) were satisfied with MSI usage. CONCLUSIONS There has been an increase in the usage of MSI among the Indian orthodontists. The knowledge, awareness and experience about MSI among Indian orthodontists was in accordance with recent global trends. The failure rate experienced by Indian orthodontists was similar to orthodontists practicing globally. KEY WORDS Mini Screw Implants (MSI), Orthodontists, Survey, India
The Role of Periodontal Disease in Preterm Labour - A Prospective Cohort Study (A Path Analysis) from Iran
Authors: Farshad Mohammad Mahdi
Published: May 2021

BACKGROUND Periodontal infections are the most common oral diseases in pregnancy. This condition can cause complications during pregnancy. Therefore, this study was designed to determine the factors affecting preterm birth and their relationship with periodontal diseases. METHODS This was a prospective cohort study and the population, consisted of old women in the age group of 18 – 45 years attending prenatal care centers in their second trimester of pregnancy. After obtaining informed and free consent from the female parent, a periodontal examination was performed and her medical information was recorded. Examination of Rumford’s teeth was performed to assess the severity of gingivitis, plaque, calculus, and attachment loss. AMOS software was used to investigate the association between preterm labor and delivery and to provide a conceptual model. RESULTS The consequences showed a direct association between preterm labour and factors, such as attachment loss, calculus, bleeding on probing (BOP), age, current diabetes, gestational diabetes, gestational hypertension, lack of calcium, folic acid, and iron supplementation, mothers’ depression, polyhydramnios, smoking severity, and history of premature rupture of the membrane. The results also indicated an indirect relationship between irregular tooth brushing and preterm birth. CONCLUSIONS Attachment loss, calculus, bleeding on probing, are directly related to premature labour and irregular tooth brushing is indirectly associated with early birth. Due to the direct relationship between periodontal diseases and preterm delivery, regular brushing, oral hygiene, oral examinations during pregnancy and follow-up treatment of periodontal disease during pregnancy are recommended.

After one year of COVID-19 Pandemic and Hundreds of Suggested Drugs, Will Cathepsin L Inhibitors be the Solution?
Authors: Ahmed Amr Kamel Khalil
Published: May 2021

Cysteine cathepsins are defined as lysosomal enzymes which are member of the papain family. Cysteine cathepsins (Cts) prevalently exist in whole organisms varying from prokaryotes to mammals and possess in their active site greatly conserved residue of cysteine. Cts are engaged in the digestion of cellular protein, activation of zymogen, and remodeling of extracellular matrix (ECM). Host cells are entered by SARS-CoV-2 via endocytosis. Cathepsin L and phosphatidylinositol 3-phosphate 5-kinase are crucial in terms of the endocytosis by cleaving the spike protein, which permits viral membrane fusion with endosomal membrane, and succeeded by the releasing of viral genome to the host cell. Thereby, inhibition of cathepsin L may be advantageous in terms of decreasing infection caused by SARS-CoV-2. Coordinate inhibition of multiple Cts and lysosomal function by different drugs and biological agents might be of value for some purposes such as parasite or viral infections and anti-neoplastic applications. It has been found that Zn
2+ deficiency or dysregulation leads to an exaggerated activity of Cysteine cathepsin increasing the autoimmune/inflammatory response. At this purpose Zn
2+ metal can be safely combined with a drug that increases the anti-proteolytic effect of endogenous Zn
2+ lowering the excessive activity of some CysCts. Biguanide derivatives complex with Zn
2+ have been found to be promising inhibitors of CysCts protease reactions. Molecular docking studies of Cathepsin L Inhibited by Metformin-Zn+2 complex have been performed showing two strong key interactions ( Cys-25&His-163) and an extra H-bond with Asp-163 compared to the co-crystallized Zn
+2 (PDB ID 4axl).
The relationship between

creativity and mental

illness: a systematic review
Authors: Ourtani Tayebeh
Published: May 2021

The association between creativity and mental disorders has been a subject of long-standing debate. And it is one of the most controversial issues in the field of creativity and psychopathology research. Despite the fact that engaging in creative activities has a wide range of benefits for mental health the concept of creativity/ mental illness has been widespread. On the one hand, a large body of anecdotal and empirical supports this association (e.g.Simonton, 2010; Andreasen, 2008; Johnson et al., 2012). On the other hand, some scholars argued that the creativity/ psychopathology connection is a traditional legend, and the empirical research in this area has many shortcomings, especially in terms of methodology (e.g. Sawyer, 2012; Schlesinger, 2009).This study conducted a systematic review to investigate the link between creativity and mental illness. Various electronic databases were used to find selected studies: including, Google Scholar, PubMed (Medline), Science Direct, and PMC (NCBI). Also, British Library, Core, and EThOS were applied to search for grey literature. In this paper, 24 studies have been reviewed that they are involved 6,525,664 participations. 21 reviewed studies provided some indications to support a positive link between creativity and psychopathology. 1 study proposed a negative link, and two studies suggested that there is no relationship. Altogether, the results displayed that there is a significant positive correlation between creativity and sub-clinical mental disorders. According to this study, not only creativity was introduced as a by-product of certain sub-clinical mental disorders (e.g., bipolar disorder, schizotypy) but it also identified as a treatment for some severe mental disorders (e.g., depression and addiction).
A Comprehensive Research Study Literature Review of EPIC© in Terms of Enabling Healthcare Agility: A Report Card
Authors: Johnson Ralph J.
Published: May 2021

Background As healthcare markets have become more dynamic and turbulent, healthcare organizations have evolved by becoming increasingly “Smart-Agile” in their business practices. Smart-Agility definition-ally ensures success due to its inherent ability to rapidly detect and react appropriately to varied and evolving unclear, complex, and seemingly tumultuous situations and produce high-quality, low-cost goods and services with high customer satisfaction. Thus, there is a vital need for Smart-Agile healthcare IT systems for collection, analyses, and reporting of substantial quantities of healthcare data to inform patient treatment and organizational decisions. EPIC® and its meaningful-use components appear increasingly popular, capturing a majority portion of the healthcare Electronic Healthcare Records (EHR) IT market (>~30%).Yet, there are few, if any, studies reporting on EPIC in terms of Smart-Agility. Aim The intent of this article is to report a systematic review of scientific literature regarding EPIC’s healthcare IT systems meaningful-use features cross-compared with Smart-Agility aspects to produce a positive vs. negative report card—and whether its features are critical vs. non-critical in terms of Smart-Agility. Method Findings reported herein derive from a grounded, iterative review of open-source, peer-reviewed scientific literature following PRISMA. Findings Report card results were mixed. EPIC clearly succeeds and excels (better than average) on Smart-Agile healthcare IT system core aspects that are the most central, critical and valuable in terms of informing healthcare organizations’ decisions and their patients’ care (6 out of 7; B+, -A), specifically: Standardized Data Collection / Connectivity, Real-Time Data Warehousing/Outcome Measures, Enhanced Patient Safety, Patient Tracking and Follow-up (Continuity of Care), Patient Involvement, and Potential Use in Medical Education. The only critical core criterion it failed on was End-User Satisfaction, and some of that appears to dissipate with new users’ software familiarity. Conclusion EPIC provides a solid and relatively inexpensive foundation with great potential for enabling Smart Agility in healthcare organizations with its high-quality collection and management of vast amounts of inter-connected raw data, auto-analysis, and fast report generation. But it does so with hidden costs and inefficiencies. Avenues of further inquiry are suggested.

Book Review: Maria Salomon Arel, English Trade and Adventure to Russia in the Early Modern Era
Authors: Hussain Shahid
Published: May 2021

Anglo-Dutch rivalry in the Early Modern Period has received significant scholarly attention, with numerous academics discussing the growing commercial rivalry that eventually culminated in a series of Anglo-Dutch wars in the second half of the seventeenth century. Scholars such as Douglas Irwin, writing in the early 1990s, focused on the growing tensions between the British East India and Dutch East India companies in the subcontinent and South-East Asia, whilst the competition between the two in the Levant and Ottoman Empire has also been well covered by historians including Alastair Hamilton, Alexander Groot and Maurits van den Boogert. In her latest work, English Trade and Adventure to Russia in the Early Modern Era, Maria Solomon Arel masterfully shifts the theatre of the rivalry to Russia. Her focus on Muscovy as a centre of Anglo-Dutch tension is refreshing, particularly given merchants involved in the Muscovy Company were also active members of other trading companies, including the Levant and East India companies.
On racial capitalism, structural change and the liquidation of Whiteness
Authors: Brazelton Bennett
Published: May 2021

This article analyses ‘racial capitalism’ as a cohesive but at times contradictory project. Understanding that both capitalism and White supremacy are constantly evolving, the objective here is to understand the political and economic currents that produce shifts in the composition and structure of institutional dispossession. To do this, I look at the abolition of slavery, the legislative victories of the civil rights movement and the current realignment of corporate classes in support of police and criminal justice reform as moments of structural change in the narrative history of ‘racial progress’ in the United States. The shifts and currents which undergird these structural changes typically occur when White supremacy challenges the integrity of capitalism and the corporate class. Expanding on existing literature that posits Whiteness as a ‘wage’, I argue that White identity functions as an asset with some level of liquidity – that is to say, it can be readily converted and exchanged. By understanding these underlying shifts and the ways in which corporate classes may seek to liquidate Whiteness, I argue, radical activists can better anticipate coming iterations of White supremacy and class exploitation.
CAMBIOS EN LA DISTRIBUCIÓN GEOGRÁFICA DE ALGUNAS ESPECIES AMERICANAS EN LA PROVINCIA DE BUENOS AIRES

Published: May 2021

La intensificación de las actividades antrópicas produce cambios en los paisajes que pueden producir modificaciones en la distribución de las especies. En la provincia de Buenos Aires se registraron plantas y animales que extendieron su hábitat hacia el sur. Aquí se analizan los casos de Glinus radiatus, Guilleminea densa y Thalia multiflora, halladas actualmente a más de 250 km del límite sur de su localización conocida. Se recolectaron ejemplares en los partidos de Azul, Las Flores y Rojas, y se revisó la bibliografía existente para ubicar registros previos y discutir las causas de su expansión. Entre las hipótesis que explican el avance de estas especies se destaca los cambios registrados en las precipitaciones y temperaturas de la región. También es posible que la restringida localización previamente publicada se deba a la insuficiencia de relevamiento, o bien los ejemplares hallados podrían constituir poblaciones relictuales, o haberse expandido favorecidos por corredores antrópicos.
BIOLOGÍA REPRODUCTIVA DE Rhodophiala bifi da (Amaryllidaceae): ASPECTOS DE APLICACIÓN EN EL MEJORAMIENTO GENÉTICO
Authors: FACCIUTO G. , COVIELLA A. , BUGALLO V.
Published: May 2021

Rhodophiala biﬁda es una especie bulbosa nativa de Argentina, Brasil, Paraguay y Uruguay. El tamaño y color de sus ﬂores la hacen muy atractiva para el cultivo ornamental. El desarrollo de protocolos de domesticación y mejoramiento genético son esenciales para poder proponerla como un nuevo cultivo, considerando que la industria ﬂorícola global requiere novedades. Como punto de partida, se hicieron estudios de compatibilidad y eﬁciencia reproductiva a través de la realización de cruzamientos controlados considerando fenotipos de ﬂores de distintos colores. Tanto la autopolinización como la polinización cruzada produjeron frutos por lo que se comprobó un sistema reproductivo mixto en R. biﬁda. La eﬁciencia reproductiva fue signiﬁcativamente mayor en la polinización cruzada que en la autopolinización siendo 49.6 y 19 respectivamente, para las ﬂores rojas, genotipo más representativo de la población. No se observó fructiﬁcación en ﬂores emasculadas sin polinizar por lo que se descartó la apomixis autónoma. Los cruzamientos entre fenotipos produjeron frutos excepto para el caso de cruzamientos entre fenotipos de ﬂores rosas por fucsias.

Published: May 2021

Tradicionalmente agricultores familiares de Neuquén (Argentina) cultivan quínoa (Chenopodium quinoa Willd.), el estudio pone en valor un material genético de quínoa en Varvarco. Se identiﬁcaron y entrevistaron a las familias guardianas de las semillas de quínoa; se realizaron observaciones del cultivo in situ y se validó la información en talleres con la comunidad. Los resultados mostraron que la quínoa forma parte del patrimonio histórico y cultural de Varvarco ya que contribuyó a la seguridad alimentaria en épocas de crisis económicas producto de distintos eventos históricos que afectaron económica y culturalmente al norte neuquino. Lleva al menos 90 años en la zona, el ciclo de cultivo es de noviembre a marzo, con características fenotípicas y de manejo similares a los materiales del Centro de Chile. El estudio mejora el conocimiento el comportamiento de la quínoa local para adaptar los calendarios, formas de manejo del cultivo, suelo y sanidad en otros agroecosistemas.
