Resiliencia y alteridad: la transformación de las prácticas artísticas desde el trabajo con “el otro”
Authors: Arias Herrera Juan Carlos
Published: September 2020

El trabajo con “el otro” es hoy ampliamente explorado en las prácticas artísticas. En países como Colombia, marcados directamente por un conflicto interno de varias décadas, la relación entre el arte y la comunidad se ha pensado muchas veces en términos de resiliencia y reconstrucción del tejido social. Se ha convertido casi en un lugar común asignarle al arte la capacidad de nombrar los traumas y de reparar a través de la narración simbólica lo que la violencia ha roto. El arte adquiere, así, un valor casi terapéutico que transforma al otro y que tiene un profundo impacto en el autor que desarrolla la práctica. El presente artículo de reflexión se concentra en este último punto: ¿qué implica para aquel que asume el rol de creador la experiencia de trabajar con otros? A través de un análisis de la noción de producción en el ámbito del arte, me interesa pensar cómo se redefine la práctica artística al enfrentarse directamente a la alteridad radical, más allá de los relatos de lecciones de vida personales y de posibles transformaciones subjetivas para los artistas.
Nadaísmo y vanguardia: porque no llegar es también el cumplimiento de un destino
Authors: Fonseca Oviedo Luis Antonio , Aguilar Diana
Published: September 2020

Este artículo de reflexión plantea un nuevo acercamiento al quehacer nadaísta y las posiciones teóricas en torno a este, con el objetivo de indagar por la categoría de artista que el nadaísmo se fijó como meta. La idea es analizar el posicionamiento del artista nadaísta dentro de las diferentes polémicas y puntos de vistas que cobijaron el advenimiento y desarrollo del nadaísmo. Así mismo, buscamos reconstruir esas polémicas que el nadaísmo suscitó en la crítica tradicional colombiana y cómo dicha producción configuró un debate en torno a los modos de institucionalización de lo literario en términos de discusiones entre tradición/periferia, centro/margen y literatura alta/literatura baja. En este orden de ideas, intentaremos dar respuesta a interrogantes como: ¿qué papel jugó la crítica colombiana en el posicionamiento del nadaísmo como grupo contestatario? ¿Cómo se configura su idea del nadaísmo a partir de los ataques a la tradición? ¿Cuáles fueron las posibilidades que el escándalo y los actos públicos le ofrecieron al desarrollo del nadaísmo como posible vanguardia? Se busca no solo responder a estos cuestionamientos sino llevar a cabo un reposicionamiento del grupo poético dentro de la tradición crítica colombiana
4. Encapsulating CRISPR/Cas13a RNPs complex and the detection system in GpVs. v1
Authors: Naranjo Briceno Leopoldo , Fuentes Keyla , David Rosales Rangel Jose
Published: September 2020

In addition to the innovative SARS-CoV-2 detection system by means APho enzymes, we propose an unprecedented design and construction of preassembled cell-derived Gigapack vesicles (termed GpV) with the stable overexpression of the hACE2 receptor, miming the SARS-CoV-2 infectious mechanisms and the virus-host interactions. GpV will be derived from the engineered hACE2 Stable Cell Line HEK-293, which is a human embryonic kidney cell line engineered to stable overexpression of hACE2. Cell line HEK-293 has been widely used in cell biology research for Spike SARS-CoV-2/hACE2 interaction studies and as a powerful tool for in vitro screening and characterization of potential drugs against SARS-CoV and SARS-Cov2. Inside of the GpV, both: i) a CRISPR/Cas13a-based nucleic-acid recognition system (SYSTEM 1), and ii) an APho-detection system (SYSTEM 2), will be encapsulated. Encapsulation of the CRISPR/Cas13a RNP complex (SYSTEM 1) and APho-detection system including its substrate (SYSTEM 2) will be performed by electroporation. We will use the guidelines given for the Neon transfection system (Invitrogen, ThermoFisher). The Neon transfection protocol is recommended for SYNTHEGO to deliver ribonucleoprotein (RNP) complexes that consist of purified Cas9 nuclease duplexed with chemically modified synthetic single-guide RNA (sgRNA) to immortalized adherent or suspension cells (https://www.synthego.com/resources/immortalized-cell-neon-electroporation-protocol).

Authors: Guerrero Pabón Mario Francisco , Bareño Lesly L , Puebla Pilar , San Feliciano Arturo
Published: September 2020

Background: Passiflora quadrangularis L. has antihypertensive and anxiolytic properties observed in experimental models. Objectives: The aim of this work was to establish the vascular effects exerted by two known monodesmosidic triterpene saponins, 3-O-β-D-glucopyranosyloleanolic acid (Compound 1) (not previously described for this plant) and, 3-O-[β-D-glucopyranosyl-(1→2)-β-D-glucopyranosyl] oleanolic acid (Compound 2), isolated from the ethanolic extract of Passiflora quadrangularis L. leaves. Methods: The structural elucidation was achieved by Nuclear Magnetic Resonance (NMR) experiments and High-Resolution Mass Spectrometry (HRMS). Aortic rings from Wistar rats, previously stimulated with phenylephrine (PE, 1µM) and washed, were exposed to cumulatively concentrations of compound 1 and compound 2 (10 to 400 µM). Ethanolic extract from leaves of P. quadrangularis L. (10 to 320 µg/mL) and clonidine (1nM to 100µM) were also used for comparison. Concentration-response curves of compounds 1 and 2 were examined in presence and absence of: endothelium, the alpha-2 antagonist yohimbine (1 and 100 µM), the alpha non-selective antagonist phentolamine (1µM), the alpha-1 antagonist prazosin (1µM) and the calcium channel blocker verapamil (10 and 100 µM). In addition, a cumulative response curve of acetylcholine (ACh, 10nM to 10µM) and sodium nitroprusside (SNP, 1nM to 100µM) were assayed in rings precontracted with compounds 1 and 2 (400 µM). Results: Compounds 1 and 2 elicited a vasoconstriction response in intact aorta rings in a similar way (pEC50: 3.92±0.01 and 4.09±0.01, respectively), the effect that did not change in denuded rings (pEC50: 3.90±0.01 and 4.11±0.01). The potency order (pEC50) of compounds 1 and 2 decreased according to the following: verapamil (3.53±0.01 and 3.90±0.02; p<0.05) < yohimbine (3.65±0.01 and 3.94±0.02; p<0.05) < prazosin (3.86±0.01 and 4.30±0.02) < phentolamine (4.05±0.02 and 4.05±0.01). SNP but not ACh, was able to decrease the vasopressor effect of compounds 1 and 2 (pIC50: 8.61±0.01 and 8.24 ± 0.15, respectively). Conclusions: Compounds 1 and 2 are key metabolites responsible for the ex vivo vasoconstrictor response induced by P. quadrangularis L. Activation of voltage-dependent calcium channels and/or α2-adrenergic receptors stimulation could be mechanisms implicated.

Acción colectiva y representación gremial: el caso de la Sociedad de Agricultores y Ganaderos del Valle del Cauca, Colombia, 1940-2002
Authors: Zuluaga Julio Cesar , Cobo Victor
Published: September 2020

Los empresarios crean asociaciones gremiales para coordinar la acción colectiva frente a otras organizaciones y grupos de interés, además de proveer bienes y servicios a sus afiliados. Este artículo explora la evolución de la Sociedad de Agricultores y Ganaderos (SAG) del Valle del Cauca desde su creación en 1937, así como los roles y funciones que asumió como representante de los intereses agrícola-ganaderos en el contexto colombiano. Con base en la revisión de actas, correspondencia, informes de presidencia y editoriales de la Revista Agrícola y Ganadera, este análisis revela la posición de la SAG frente a tres proyectos: la misión del Banco Mundial liderada en 1950 por Lauchlin B. Currie; la aplicación del programa de inversiones propuesto por David Lilienthal en 1954; y la Ley 135 de 1961 o Ley de Reforma Agraria. Con ello, se demuestra que el comportamiento de la SAG estuvo determinado por la lógica de la influencia y la lógica de los servicios.
Investigating the Quranic Proposition “وَ إِنْ يَرَوْا كُلَّ آيَةٍ لا يُؤْمِنُوا بِها”, Regarding to Syntagmatic Relations and Thematic Content Analysis
Authors: Tayyarinejad Ramin , Hajikhani Ali
Published: September 2020

One of the Divine ubiquitous and eternal traditions has been to invite people to Faith through sending messengers. This invitation to Allah was usually accompanied by presenting a verse or a collection of verses which indicate the connection of the Messenger with the unseen world. The Qur’anic verses proves that the reaction of people to the prophets’ invitation, has been done in three levels: disregard for the invitation, minimum acceptance, or maximum denial of the invitation. The Qur’anic proposition «وَ إِنْ يَرَوْا كُلَّ آيَةٍ لا يُؤْمِنُوا بِها» points to the definite unbelief of a group of people in all verses presented by the prophets. This research aims to discover the origin of this proposition and the reason of the denial, which is undergone through the exploratory method of thematic content analysis and the use of syntagmatic relations in the discourse analysis. Findings show that this proposition is used in two positions of the Qur’an and in a single context. It is in syntagmatic relation to the theme of “denial” and the denialist people are its main origin. Content analysis of the theme of “denial” shows that human beings went to the position of denying religion because of committing “oppressive behaviors” and “continuous fisq (evils/sins)” and thus the denial of religion has made them “soul-losing” and consequently “unbelief”.

Authors: Rostami Yekta Fayyaz , Allahbedashti Ali
Published: September 2020

In order to know a scientific discipline or to establish a scientific major, it is necessary to study and identify the epistemological geometry of that discipline or major. This includes categories such as definition, purpose, subject, duties and responsibilities, methods and issues. It seems necessary to establish the major of “social theology” in the science of “Islamic theology”, aiming at “presenting the social dimensions of doctrinal teachings”, “analyzing new social issues related to doctrinal principles” and “responding to the mass of social misconceptions about religious teachings”. The present paper explains and analyzes the epistemological geometry of Islamic social theology.

Covid 19 – A Major Cause of Digital Transformation in Education or Just an Evaluation Test
Authors: Mladenova Tsvetelina , Kalmukov Yordan , Valova Irena
Published: September 2020

This paper presents a detailed comparative analysis of the three types of eLearning (synchronous, asynchronous and hybrid) and the traditional onsite learning. The analysis considers the opinions of both teachers (the three of us) and students. We have surveyed our students twice. First time, at the end of the winter semester (end of January) - right before the Covid-19 outbreak in Europe. Then we did it again at the end of the summer semester (end of May) that coincides with the end of the first peak of the first pandemic wave in Europe. Since the first survey evaluates mostly students' attitude, the second one evaluates their real-life experience. Young people nowadays belong to the so called digital generation, so we expected that students are actually happier with eLearning rather than the traditional onsite learning. But surprisingly their opinion about pros and cons of eLearning closely resembles ours.

This is a conceptual approach to knowledge acquisition at technical universities. The emphasis is on the consistent possession of knowledge: the acquisition of new and preservation of the existing ones. At the same time, the grapho-geometric component in technical education is one of the most important elements of fundamental (general engineering) education. It is carried out at the initial stage in the process of studying technical disciplines included in the relevant curricula. Applied geometry plays an important role in this process, and it includes such directions as descriptive geometry, analytic geometry, engineering graphics, and computer graphics that provide spatial interpretation of geometric objects and display them on a plane. This combination of subjects studied significantly enriches the geometric development within student's intellectual world.

Authors: Pamulapati Lauren G. , Hess Danielle
Published: September 2020

With a primary care physician shortage, utilization of pharmacists in the ambulatory care setting has proven to have positive economic and clinical outcomes for the practice and for patients. To extend the reach of the pharmacists, students may assist with patient care activities, such as medication reconciliation, point-of-care testing, and counseling. Evidence has shown that students benefit in building confidence, as well as improved perceptions of interprofessional care, while positive patient outcomes are maintained. There are many methods for schools to integrate these experiences early into their curriculum, as well as for students to explore opportunities on their own.

Authors: Camacho-Montaño Andrés Mauricio , Niño-Alba Reinaldo
Published: September 2020

Objetivo: reportar un caso de mola parcial con feto vivo y realizar una revisión de la literatura sobre las complicaciones maternas y fetales asociadas a esta condición.Materiales y métodos: se presenta el reporte de un caso de mola parcial y feto vivo de 33 semanas, complicado por restricción de crecimiento intrauterino, oligoamnios y preeclampsia severa. Después de seguimiento del recién nacido a un año reportamos un resultado satisfactorio materno-fetal. Se realiza una búsqueda de la literatura en Medline vía PubMed, LILACS, OVID, Uptodate y Google Scholar, con los siguientes términos MESH: “hiditadiform mole”, “partial mole”, “live fetus”, “coexisting live fetus”. Se seleccionaron estudios de series de caso y reportes de caso de gestantes con coexistencia de mola parcial y feto vivo al momento del diagnóstico, y se extrajo información sobre el pronóstico materno-fetal. Resultados: se identificaron inicialmente 129 títulos relacionados, de los cuales 29 cumplieron los criterios de inclusión, 4 artículos fueron excluidos por no obtener acceso al texto completo. Se analizaron 31 casos reportados, 9 casos terminaron en aborto, 8 terminaron en óbito o muerte perinatal y 14 (45%) casos terminaron con un recién nacido vivo. La complicación materna más frecuente fue preeclampsia, en 6 (19,35%) casos. Conclusión: la coexistencia de mola parcial con feto vivo presenta un riesgo alto de resultado perinatal adverso y preeclampsia. Se requiere más información sobre esta rara condición para determinar de mejor manera posibles intervenciones en los casos de fetos euploides y dar una adecuada asesoría en la práctica clínica, por lo que es importante el reporte de estos casos para tener suficiente evidencia sobre el comportamiento natural de la enfermedad.
Análisis de los lineamientos metodológicos de la Comisión para el Esclarecimiento de la Verdad, la Convivencia y la No Repetición en Colombia
Authors: Hernández Pérez Mauricio
Published: September 2020

A causa del conflicto armado interno, Colombia ha implementado prácticas memoriales y de verdad que se pueden identificar como tecnologías políticas de la verdad y la memoria. Con base en esto, en el artículo se analizan los lineamientos metodológicos de la Comisión para el Esclarecimiento de la Verdad, la Convivencia y la No Repetición (CEV). Se procede mediante un enfoque cualitativo de orden descriptivo, interpretativo y analítico para abordar el documento Lineamientos metodológicos. Escuchar, reconocer y comprender para transformar de la CEV (2019). Desde el aspecto metodológico, se identifica hasta qué punto la CEV contribuirá a complementar las “zonas grises” y los vacíos que se han generado hasta el momento en materia de reconstrucción de memoria. Asimismo, se expone que la relación entre la memoria y la verdad, aunque necesaria, es tan insuficiente como incompleta, en parte porque existe un relato de verdad y memoria aún abierto, y porque diversos factores, como el corto tiempo con que cuenta la CEV para su mandato, dificultan que se alcance el objetivo último en su totalidad

PERAMALAN KINERJA PERUSAHAAN PERBANKAN TAHUN 2017 YANG TERDAFTAR DI BURSA EFEK INDONESIA DENGAN METODE ARCH-GARCH
Authors: Wijaya John Henry , Nugraha Nugi Mohammad
Published: September 2020

This study aims to determine how the forecasting of banking stock performance in 2017 is measured weekly using the ARCH-GARCH method. There were 43 registered banking companies listed on the Indonesia Stock Exchange, but only 39 companies used as the research sample based on data completeness. The ARCH-GARCH method was used in the forecasting process. Results showed that the value of the mean absolute per cent error was 8.52% or below 10%. Therefore, the ARCH-GARCH method was quite good at predicting the performance of the banking sector. With a high level of complexity, the ARCH-GARCH method could provide a more realistic description than other methods to help investors make decisions. The banking sector tends to experience a downturn. Thus, it would be better for investors to hold back the intention to invest in banking stocks unless they are the risk-takers.

Global economic policy uncertainty will influence economic stability among countries integrated into international trade. The trade war between America and China has affected the weakening of macroeconomic indicators in developing countries, one of which is Indonesia. The objective of this study is to examine the influence of China's economic policy uncertainty and macroeconomic indicators, i.e., inflation, investment, and Brent oil price, on Indonesia's economic growth. Research data were secondary time series data taken from the Q1 2009-Q4 2018 quarterly period. The method of analysis used is the Vector Error Correction Model (VECM). Results showed that in the long run, the uncertainty of China's economic policy and Brent oil price could negatively influence Indonesia's economic growth. On the other hand, inflation, in the long run, had a positive and significant influence on Indonesia's economic growth. Meanwhile, investment did not have a significant influence on Indonesia's economic growth.

Quality of product in various industries, especially in metal industry is the most attention so the product can compete and attract consumers. Surface roughness is one of the demand that must be fulfilled because it can be the initiation of cracks, especially when material receives recurring and fluctuating loading. Therefore, low surface roughness can produce a product with longer lifespan material. The goal of this study is to determine the most optimal combination of electroplating process with factors variety of voltage (volts), temperature (℃), and time of immersion (minutes) to produce a low values of surface roughness. This study uses an experimental design with Taguchi method. Contribution factors of control that produce the surface roughness values ​​were influenced significantly by control factor voltage (volts) amounted to 77.31% with an average roughness value of 1.29 μm. This is due to the increase in voltage which causes the deposition of electrolyte ions which is faster in the deposition structure of the specimen. Where as other control factors were not effected significantly on the temperature control factor amounted to 4.85% with an average roughness value of 1,32 μm. These results are possible because the temperature variations used (40℃ to 50℃) are still within the optimum operating temperature. And the other control factors is immersion time amounted to 10.13% with an average roughness value of 1,32. The result ware obtained because the length of coating time affected the quantity of deposition of nickel ions on the surface of the specimen. The result of optimal condition is  the voltage level 2 (6 volts), the temperature at level 2 (45℃), and the immersion time at level 3 (25 minutes).

Niedyskursywna pamięć traumatyczna a tożsamość zbiorowa. Romowie wobec doświadczenia zagłady
Authors: Kapralski Sławomir
Published: September 2020

Przedmiotem artykułu jest romska pamięć niedyskursywna, czyli niewyrażana w mowie czy w piśmie obecność przeszłości w praktykach, relacjach, strukturach społecznych i hierarchiach kulturowych. Ta forma pamięci odgrywa szczególnie istotną rolę w wypadku Romów, a więc sieci zbiorowości, które w przeszłości miały utrudniony dostęp do środków wytwarzania pamięci zbiorowej. Autor nawiązuje do teorii systemów i antropologii symbolicznej Mary Douglas, by pokazać, w jaki sposób lęki spowodowane przez traumatyczne wydarzenia historyczne, związane z naruszeniem zewnętrznej granicy społeczności romskiej, są w niedyskursywny sposób kodowane w jej strukturze społecznej i kulturze. W konsekwencji autor stawia tezę, że niemożność kontroli granicy zewnętrznej (na przykład skutecznej obrony przed prześladowaniami) prowadzi do kompensacyjnej kontroli granic wewnątrzgrupowych (na przykład wzmocnienia patriarchalnej relacji między kobietami a mężczyznami). Tezę tę potwierdza odmienny status kobiet w skądinąd kulturowo podobnych grupach polskich Romów Karpackich i Romów słowackich, który badacz wyjaśnia odmiennymi dla obu grup doświadczeniami II wojny światowej i związanymi z tym różnymi formami pamięci niedyskursywnej.

Insurance is an attempt of risk diversion by the insured person to the insurance company. The risk is referred to the future event that will potentially cause a financial loss. Based on many risk factors,the status of insurance was divided into a single decrement and a multiple decrement. In single decrement, the only factor caused benefit payment is death, while in multiple decrement there is more than one factors caused benefit payment. As a consequence, beside the random variable of time until termination , there is another random variable appears that is the cause of decrement . The aim of this study was to describe the development process of a multiple decrement table and determine net single premium based on multiple decrement status. This study was conducted by describing the construction process of components in the multiple decrement table using joint distribution and marginal distribution for each random variable. This study is a various equation for constructing a multiple decrement table was obtained. That probability equation was also used to form the net single premium equation of term insurance based on multiple decrement status by using probability function of time until termination and cause of termination. Keywords: Term Insurance, Multiple Decrement, Net Single  Premium
A Fully Automated Deep Learning-based Network For Detecting COVID-19 from a New And Large Lung CT Scan Dataset
Authors: Rahimzadeh Mohammad , Attar Abolfazl , Sakhaei Seyed Mohammad
Published: September 2020

COVID-19 is a severe global problem, and AI can play a significant role in preventing losses by monitoring and detecting infected persons in early-stage. This paper aims to propose a high-speed and accurate fully-automated method to detect COVID-19 from the patient's CT scan images. We introduce a new dataset that contains 48260 CT scan images from 282 normal persons and 15589 images from 95 patients with COVID-19 infections. At the first stage, this system runs our proposed image processing algorithm to discard those CT images that inside the lung is not properly visible in them. This action helps to reduce the processing time and false detections. At the next stage, we introduce a novel method for increasing the classification accuracy of convolutional networks. We implemented our method using the ResNet50V2 network and a modified feature pyramid network alongside our designed architecture for classifying the selected CT images into COVID-19 or normal with higher accuracy than other models. After running these two phases, the system determines the condition of the patient using a selected threshold. We are the first to evaluate our system in two different ways. In the single image classification stage, our model achieved 98.49% accuracy on more than 7996 test images. At the patient identification phase, the system correctly identified almost 234 of 245 patients with high speed. We also investigate the classified images with the Grad-CAM algorithm to indicate the area of infections in images and evaluate our model classification correctness.

Space missions have always assumed that the risk of spacecraft malfunction far outweighs the risk of human system failure. This assumption breaks down for longer duration exploration missions and exposes vulnerabilities in space medical system. Space agencies can no longer buy down the majority of human system risk through the crew member selection process and emergency re-supply or evacuation. No mature medical solutions exist to close the risk gap. With recent advances in biotechnology, there is promise in augmenting a space pharmacy with a biologically-based space foundry for on-demand manufacturing of high-value medical products. Here we review the challenges and opportunities of molecular pharming, the production of pharmaceuticals in plants, as the basis of a space medical foundry to close the risk gap in current space medical systems. Plants have long been considered an important life support object in space and can now also be viewed as programmable factories in space. Advances in molecular pharming-based space foundries will have widespread application in promoting simple and accessible pharmaceutical manufacturing on Earth.
Supporting Children’s Independent Activities in Smart and Playable Public Places
Authors: Garau Chiara , Annunziata Alfonso
Published: September 2020

The global process of urbanization, and the modification of social interaction determined by the pandemic crisis poses the issue of the place of vulnerable users, and in particular children, within the contemporary city. This research aims to elaborate a theoretical and methodological framework, based on the concepts of affordance and capability, for analyzing the potential of public spaces to enable and support children’s independent activities. This potential, or meaningful usefulness, is expressed by the Index of Meaningful Usefulness of public Urban Spaces (IUIS). The latter is calculated via the tool ‘Opportunities for Children in Urban Spaces’ (OCUS). This methodology is applied to the analysis of significant public spaces within the historic center of the city of Iglesias in Sardinia, Italy. The results reveal adequate usefulness of the selected spaces, while underlining criticalities related to intrinsic spatial and physical attributes. The application to the case study confirms the validity of the theoretical and methodological framework embodied in the OCUS tool for supporting urban design and planning by orienting place-shaping processes towards the acknowledgement of children’s needs.
Causal Connection and Global Consciousness (Is Individuality an Evolutionary Accident?)
Authors: De Angelis Alessandro
Published: September 2020

We propose a novel interpretation of consciousness and an enlarged definition of locality, which provide a solution to the problem of the consistency of measurements in quantum mechanics: consciousness is a characteristics of the Universe as a whole. Besides its physical consequences, this interpretation has also moral implications: individuality comes out naturally to be just an accident functional to evolution which shaped past and present history through competition, and realizing this fact should enforce cooperation.
Input-to-state Stability in the Meaning of Switching for Delayed Feedback Switched Stochastic Financial System
Authors: Rao Ruofeng
Published: September 2020

Financial system is essentially chaotic and unstable if there is not any external inputs. By means of Lyapunov function method, design of switching law, novel fuzzy assumption, $L^p$ estimation technique and Laplace semigroup theory, the author presents the boundedness and LMI-based (globally) asymptotical input-to-state stability criteria of financial systems. Particularly, the globally asymptotical stability in the meaning of switching implies that when the time $t$ is big enough, the dynamic of any subsystem must approach its unique equilibrium point. Besides, the global financial crisis often erupts periodically, which illuminates that the global stability in the classical sense is actually meaningless. So the stability in the meaning of switching proposed in this paper is suitable and appropriate. Numerical examples illuminate the effectiveness of the obtained results.

Authors: Morales Samuel , Ruiz Miriam , Soria Juan
Published: September 2020

This study has been monitored for five years by Sentinel-2 satellite images, at different seasons of the year, of the fluctuations in the water level of the Gallocanta Lake (between the provinces of Teruel and Zaragoza, Aragón, Spain) considered a hypersaline and endorheic wetland, which has characteristics that make it unique in the geographical area in which it is located, as well as for the operation of the system. Rainfall in the area has a wide variation giving the maximums in the months of May and June and the minimums in January and February. There are considerable fluctuations in the water level from the almost total drying of the lagoon to the filling with a depth of approximately 3 meters.
PARP1 Deficiency Reduces Tumour Growth by Decreasing E2F1 Hyperactivation: A Novel Mechanism Beyond PARP Enzymatic Inhibition in the Treatment of Cancer

Published: September 2020

In recent years, poly (ADP-ribose) polymerase (PARP) inhibitors have heen evaluated for treating homologous recombination-deficient tumors, taking advantage of synthetic lethality. However, increasing evidence indicates that PARP proteins exert several cellular functions unrelated with their role on DNA repair, including function as a co-activators of transcription through protein-protein interaction with E2F1. Since the RB/E2F1 pathway is among the most frequently mutated in many tumours types, we investigated whether the absence of PARP activity could counteract the consequences of E2F1 hyperactivation. Our results demonstrate that genetic ablation of Parp1 extends the survival of Rb-null embryos, while genetic inactivation of Parp1 results in reduced development of pRb-dependent tumors. Our results demonstrate that PARP1 plays a key role as a transcriptional co-activator of the transcription factor E2F1, an important component of the cell cycle regulation. Furthermore, impairment of PARP results in a reduction of tumor growth, that is not depending of the activity of PARP on DNA repair. Considering that most oncogenic processes are associated with cell cycle deregulation, the disruption of this PARP1-E2F1 interaction could provide a new therapeutic target of great interest and a wide spectrum of indications.

Published: September 2020

Digital enabled manufacturing systems require high level of automation for fast and low-cost production but should also present flexibility and adaptiveness to varying and dynamic conditions in their environment, including the presence of human beings. This issue is addressed in this work by implementing a reliable system for real-time safe human-robot collaboration based upon the combination of human action and contact type detection systems. Two datasets containing contact and vision data are collected by using different volunteers. The action recognition system classifies human actions using the skeleton representation of the latter when entering the shared workspace and the contact detection system distinguishes between intentional and incidental interactions if a physical contact between human and robot takes place. Two different deep learning networks are used for human action recognition and contact detection which in combination, lead to the enhancement of human safety and an increase of the level of robot awareness about human intentions. The results show a promising path for future AI-driven solutions in safe and productive human–robot collaboration (HRC) in industrial automation.
Photoperiodic Response of in vitro Cannabis sativa Plants
Authors: Moher Melissa , Jones Max , Zheng Youbin
Published: September 2020

Most commercial Cannabis sativa L. (cannabis) genotypes are short-day plants and cultivators typically use a 12.0 h uninterrupted dark period to induce flowering; however, scientific information is lacking to prove this is the optimal dark period for all genotypes, and cultivar specific photoperiods may increase productivity. Tissue culture can be used for research requiring multiple treatments, proper replication, and in a controlled environment on a smaller scale compared to greenhouse and indoor facilities. To determine whether cannabis explants can flower under varied photoperiods in vitro, explants were grown under one of six photoperiod treatments: 12.0, 13.2, 13.8, 14.4, 15.0, and 16.0 h for four weeks. The percentage of flowering explants was highest under 12.0 and 13.2 h treatments. There were no treatment effects on the fresh weight, final height, or growth index of the explants. The results suggest an uninterrupted dark period of at least 10.8 h (i.e. 13.2 h photoperiod) is needed to induce the flowering of this genotype. In vitro flowering could provide a unique and high throughput approach to study floral/seed development and secondary metabolism in cannabis under highly controlled conditions. Further research should determine if this response is the same on a whole plant level.

Authors: Vaidis Maxime , Otis Martin J.-D.
Published: September 2020

As a result of extensive research in the field of mobile robots (rovers) and swarms, a number of algorithms exist to assist them for executing a mission in the three levels of software architecture: strategic (interaction loop level), tactic (planning) and operational (sensing, control and actuation). They allow them to achieve their goals while adapting to their environment through a multitude of methods designed for each situation. For this reason, a literature review of the latest research conducted in previous years is required to identify new research trends in human-swarm interaction applied to help humans in hazardous environment such as militarized zone. In this paper, we will present some interesting algorithms for interactive and autonomous mobile robots acting in swarms in an open and crowded environment. A discussion will focus on comparing different algorithms and their advantages and disadvantages.

Mens sana in corpore sano: Does the Glycemic Index Have a Role to Play?
Authors: Carneiro Lionel , Leloup Corinne
Published: September 2020

Although diet interventions are mostly related to metabolic disorders, nowadays they are used in wide variety of pathologies. From diabetes and obesity to cardiovascular diseases, through cancer or neurological disorders and stroke, nutritional recommendations applied to almost all diseases. Among those disorders, metabolic disturbances and brain function and/or diseases have recently been shown to be linked. Indeed, numerous neurological functions are often associated with perturbations of whole-body energy homeostasis. In this regard, specific diets are used in various neurological conditions such as epilepsy, stroke, or seizure recovery. In addition, Alzheimer’s disease or Autism Spectrum Disorders are also considered as putatively improved by diet intervention. Glycemic index diets are a novel developed indicator expected to anticipate the changes in blood glucose induced by specific foods, and how they can affect various physiological function. Several results provide indications of efficiency of low glycemic index diets in weight management, insulin sensitivity, but also cognitive function, epilepsy treatment, stroke, or neurodegenerative diseases. Overall, studies involving glycemic index could provide new insight in the relationship between energy homeostasis regulation and brain function or related disorders. Therefore, in this review we will summarize main evidences on glycemic index involvement in brain mechanisms of energy homeostasis regulation.
