A high-resolution search for the Hα emission line of the accreting companion GQ Lup b with ESPRESSO
Authors: Houllé Mathis , Sedaghati Elyar , Figueira Pedro , Vigan  Arthur
Published: July 2021

In the current theories of planet formation, the amount of energy that a forming gas giant retains from its accretion flow is still unknown. This unconstrained parameter has a large impact on the post-formation evolution of the new planet, as it defines its initial temperature and luminosity. Models have been developed, ranging from “hot-start” models assuming that all the energy is retained internally, to “cold-start” ones assuming that everything is radiated away, and "warm-start" ones in between. Their coexistence introduces large degeneracies on the determination of age and mass in direct imaging observations, as these studies use the cold or hot-start models to infer these parameters from the observed luminosity of a planet. A promising way of solving this problem is the study of atomic emission lines originating from the hot gas shocked by the accretion flow. Recently, Aoyama et al. (2018, 2020) presented simulations of hydrogen lines emitted by the accretion shock onto the circumplanetary disk and the planetary surface. They showed that the line luminosity and width can be used to infer the protoplanet mass, thus giving an estimation that is independent from the evolution models. They applied it to the case of PDS70 b and c (Aoyama & Ikoma 2019, Hashimoto et al. 2020), but were ultimately limited by the spectral resolution of the MUSE observations they used (R ~ 2500). In this context, our team recently proposed and carried out a pilot program using the VLT/ESPRESSO fiber-fed spectrograph, equipped with very high resolution (R = 190 000), to characterize the Hα line of the young substellar companion GQ Lup b. We will present in this poster how these observations were conducted, the methods used to remove the contamination from the host star, and the results we obtained.

Therefore, the research activities of group were categorized into two: Environmental and Life sciences. The environmental science team studies the physical evolution of the other planets in our solar system using data from various missions like MAVEN (Mars Atmospheric and Volatile EvolutioN), while the life science team are looking at the probability of finding life elsewhere in our solar system. So far some of researches had been published by these teams, while more are various levels of development. Some of the researches are on evolutionary panspermia and meteorite sample analysis.Our research activities have been enhanced through collaborations such as the PAPSSN project, analysis of meteorite samples at University of Witwatersrand in South Africa etc.
The Moroccan experience on Meteoritics and Planetary Science
Authors: Chennaoui Aoudjehane Hasnaa
Published: July 2021

Morocco is a treasure house of meteorites, most meteorites accessible to scientists and collectors in all over the world are originated from Morocco and surrounding countries. Collection of meteorites is essentially done in hot and cold deserts. Morocco has a large and safe Sahara where many nomads are living. A big community of meteorite hunters is well established. Nomads and hunters are good observers, they learned by practicing how to make the difference between terrestrial and extra-terrestrial rocks that represent an important source of revenue for them. Those meteorites are almost all exported. All classes of meteorites are found in the hot deserts including many rare and important for scientific research ones.Since 2001, our team in the Hassan II University of Casablanca Faculty of Science Ain Chock is working on the promotion of meteorites in Morocco, Arab countries and Africa. Cosmochemistry courses has been introduced to the national curricula. Many PhD thesis has been prepared and defended. Since 2004 meteorite falls in Morocco have been classified and submitted to the Nomenclature Committee of the Meteoritical Society by our team, including the exceptional fifth Martian meteorite fall in Morocco “Tissint”. Many valuable papers have been published on these falls.On 2019, ATTARIK Foundation for Meteoritics and Planetary Science was created by our team and a group of passionate people. The aim of ATTARIK is to support the research of the PhD students on Planetary Sciences and to disseminate sciences through youth in cities and countryside. The Africa Initiative for Planetary and Space Science was launched on 2016 in Cape Town has similar objectives.The Moroccan experience can be a good reference to development of planetary sciences in Africa and the Arab countries.

2021 DW1 was discovered on 16 February 2021 by Pan-STARRS 1 on Haleakala. This ~40-m object passed the Earth at a distance of 570000 km (1.5 Lunar Distance) on 4 March at 9 UTC, reaching a brightness of V=14.6 mag.  We observed it photometrically from 2 March, 4 UTC, when it was visible at V=16.5 mag, until 7 March, 9 UTC (V=18.2 mag).  During that time 2021 DW1 swept a 170 deg long arc in the northern sky, spanning solar phase angles in the range from 36 to 86 deg. This made it an excellent target for physical characterization.In our campaign, we used 9 telescopes with apertures ranging from 0.3-m to 1.2-m, located in the USA, UK, Spain, Italy, Poland, Ukraine, and South Korea. This gave us a good coverage of the asteroid path. We collected a lot of data which are now being analysed. Preliminary analysis show a very short rotation period of 50 seconds and a lightcurve amplitude of about 0.3 mag, which didn't change much along the asteroid path in the sky. More results will be presented at the conference.
Forming planets around stars with non-solar composition
Authors: Jorge David , Kamp Inga , Waters Rens , Woitke Peter , Spaargaren Rob
Published: July 2021

AbstractWe aim to understand the impact of different refractory element ratios such as Mg, Si, and Fe on the composition of planets. We use the thermodynamic equilibrium code GGchem to simulate the condensation of solids in a minimum mass solar nebula around main sequence G-type stars within 150pc. We extract the stellar elemental composition from the Hypatia database. We find that a lower Mg/Si ratio shifts the condensation sequence from forsterite and SiO to enstatite and quartz; a lower Fe/S ratio leads to the formation of FeS and FeS2 and little or no Fe-bearing silicates. Ratios of refractory elements translate directly from the gas phase to the condensed phase for T

Abstract. Water clarity provides a sensitive tool to examine spatial pattern and historical trend in lakes trophic status. Yet, this metric has insufficiently been explored despite the availability of remotely-sensed data. We used three Secchi disk depth (SDD) datasets for model calibration and validation from different field campaigns mainly conducted during 2004–2018. The red/blue band ratio algorithm was applied to map SDD for lakes (> 1 ha) based on the first SDD dataset, where R2 = 0.79, RMSE = 100.3 cm, rRMSE = 61.9 %, MAE = 57.7 cm. The other two datasets were used to validate the SDD estimation model, which were indicated the model had a stable performance of temporal transferability. The annual mean SDD of lakes were retrieved across China using Landsat top of air reflectance products in GEE from 1984 to 2018. The spatiotemporal dynamics of SDD were analysed at the five lake regions and individual lake scales, and the average, changing trend, lake number and area, and spatial distribution of lake SDDs across China were presented. In 2018, we found that the lakes with SDDs < 2 m accounted for the largest proportion (80.93 %) of the total lakes, but the total area of lakes with SDD between 0–0.5 m and > 4 m were the largest, accounting for 48.28 % of the total lakes. During 1984–2018, lakes in the Tibetan-Qinghai Plateau lake region (TQR) had the clearest water with an average value of 3.32 ± 0.38 m, while that in the Northeastern lake region (NLR) exhibited the lowest SDD (mean: 0.60 ± 0.09 m). Among the 10,814 lakes with SDD results more than 10 years, 55.42 % and 3.49 % of lakes experienced significant increasing and decreasing trends, respectively. At the five lake regions, except for the Inner Mongolia-Xinjiang lake region (MXR), more than half of the total lakes in every other lake region exhibited significant increasing trends. In the Eastern lake region (ELR), NLR and Yungui Plateau lake region (YGR), almost more than 50 % of the lakes that displayed an increase or decrease in SDD were mainly distributed in an area of 0.01–1 km2, whereas that in the TQR and MXR were primarily concentrated in large lakes (> 10 km2). Spatially, lakes located in the plateau regions generally exhibited higher SDD than those situated in the flat plain regions.

Testing the reliability of interpretable neural networks in geoscience using the Madden–Julian oscillation
Authors: Toms Benjamin A. , Kashinath Karthik ,   Prabhat, Yang Da
Published: July 2021

Abstract. We test the reliability of two neural network interpretation techniques, backward optimization and layerwise relevance propagation, within geoscientific applications by applying them to a commonly studied geophysical phenomenon, the Madden–Julian oscillation. The Madden–Julian oscillation is a multi-scale pattern within the tropical atmosphere that has been extensively studied over the past decades, which makes it an ideal test case to ensure the interpretability methods can recover the current state of knowledge regarding its spatial structure. The neural networks can, indeed, reproduce the current state of knowledge and can also provide new insights into the seasonality of the Madden–Julian oscillation and its relationships with atmospheric state variables. The neural network identifies the phase of the Madden–Julian oscillation twice as accurately as a linear regression approach, which means that nonlinearities used by the neural network are important to the structure of the Madden–Julian oscillation. Interpretations of the neural network show that it accurately captures the spatial structures of the Madden–Julian oscillation, suggest that the nonlinearities of the Madden–Julian oscillation are manifested through the uniqueness of each event, and offer physically meaningful insights into its relationship with atmospheric state variables. We also use the interpretations to identify the seasonality of the Madden–Julian oscillation and find that the conventionally defined extended seasons should be shifted later by 1 month. More generally, this study suggests that neural networks can be reliably interpreted for geoscientific applications and may thereby serve as a dependable method for testing geoscientific hypotheses.

Abstract. Skilful hydrological forecasts can benefit decision-making in water resources management and other water-related sectors that require long-term planning. In Ireland, no such service exists to deliver forecasts at the catchment scale. In order to understand the potential for hydrological forecasting in Ireland, we benchmark the skill of ensemble streamflow prediction (ESP) for a diverse sample of 46 catchments using the GR4J (Génie Rural à 4 paramètres Journalier) hydrological model. Skill is evaluated within a 52-year hindcast study design over lead times of 1 d to 12 months for each of the 12 initialisation months, January to December. Our results show that ESP is skilful against a probabilistic climatology benchmark in the majority of catchments up to several months ahead. However, the level of skill was strongly dependent on lead time, initialisation month, and individual catchment location and storage properties. Mean ESP skill was found to decay rapidly as a function of lead time, with a continuous ranked probability skill score (CRPSS) of 0.8 (1 d), 0.32 (2-week), 0.18 (1-month), 0.05 (3-month), and 0.01 (12-month). Forecasts were generally more skilful when initialised in summer than other seasons. A strong correlation (ρ=0.94) was observed between forecast skill and catchment storage capacity (baseflow index), with the most skilful regions, the Midlands and the East, being those where slowly responding, high-storage catchments are located. Forecast reliability and discrimination were also assessed with respect to low- and high-flow events. In addition to our benchmarking experiment, we conditioned ESP with the winter North Atlantic Oscillation (NAO) using adjusted hindcasts from the Met Office's Global Seasonal Forecasting System version 5. We found gains in winter forecast skill (CRPSS) of 7 %–18 % were possible over lead times of 1 to 3 months and that improved reliability and discrimination make NAO-conditioned ESP particularly effective at forecasting dry winters, a critical season for water resources management. We conclude that ESP is skilful in a number of different contexts and thus should be operationalised in Ireland given its potential benefits for water managers and other stakeholders.
Lateral thermokarst patterns in permafrost peat plateaus in northern Norway

Published: July 2021

Abstract. Subarctic peatlands underlain by permafrost contain significant amounts of
organic carbon. Our ability to quantify the evolution of such permafrost
landscapes in numerical models is critical for providing robust predictions of
the environmental and climatic changes to come. Yet, the accuracy of
large-scale predictions has so far been hampered by small-scale physical processes
that create a high spatial variability of thermal surface conditions,
affecting the ground thermal regime and thus permafrost degradation
patterns. In this regard, a better understanding of the small-scale
interplay between microtopography and lateral fluxes of heat, water and snow
can be achieved by field monitoring and process-based numerical modeling.
Here, we quantify the topographic changes of the Šuoššjávri
peat plateau (northern Norway) over a three-year period using drone-based
repeat high-resolution photogrammetry. Our results show thermokarst
degradation is concentrated on the edges of the plateau, representing 77 %
of observed subsidence, while most of the inner plateau surface exhibits no
detectable subsidence. Based on detailed investigation of eight zones of the
plateau edge, we show that this edge degradation corresponds to an annual
volume change of 0.13±0.07 m3 yr−1 per meter of retreating
edge (orthogonal to the retreat direction). Using the CryoGrid3 land surface model, we show that these degradation
patterns can be reproduced in a modeling framework that implements lateral
redistribution of snow, subsurface water and heat, as well as ground
subsidence due to melting of excess ice. By performing a sensitivity test
for snow depths on the plateau under steady-state climate forcing, we obtain
a threshold behavior for the start of edge degradation. Small snow depth
variations (from 0 to 30 cm) result in highly different degradation
behavior, from stability to fast degradation. For plateau snow depths in the range of field measurements, the simulated annual volume changes are broadly in agreement with the results of the drone survey. As snow depths are clearly correlated with ground surface temperatures, our results indicate
that the approach can potentially be used to simulate climate-driven
dynamics of edge degradation observed at our study site and other peat
plateaus worldwide. Thus, the model approach represents a first step
towards simulating climate-driven landscape development through thermokarst
in permafrost peatlands.

Awareness and Perception of Cybercrimes and Cybercriminals
Authors: Lee Hannarae , Lim Hyeyoung
Published: July 2021

Awareness is a starting point to recognize, understand, or know a situation or fact, and the perception makes a difference in how to deal with it. Although the term cybercrime may not be new to the most public and the police, not all of them are well aware of the nature and extent of cybercrimes, cybercriminals, and cyber-victims, which in turn affects their perceptions of matters. The four papers in this issue of the International Journal of Cybersecurity Intelligence and Cybercrime empirically examine these important topics and discuss policy implications.
Cybercrime and Digital Forensics: Bridging the gap in Legislation, Investigation and Prosecution of Cybercrime in Nigeria
Authors: Mohammed Kabiru H. , Mohammed Yusuf D. , Solanke Abiodun A.
Published: July 2021

The advancement of Information and Communication Technologies (ICT) opens new avenues and ways for cybercriminals to commit crime. The primary goal of this paper is to raise awareness regarding gaps that exist with regards to Nigeria’s capabilities to adequately legislate, investigate and prosecute cases of cybercrimes. The major source of cybercrime legislation in Nigeria is an act of the National Assembly which is majorly a symbolic legislation rather than a full and active legislation. In perusing these avenues of inquiry, the authors seek to identify systemic impediments which hinder law enforcement agencies, prosecutors, and investigators from properly carrying out their duties as expected.
A Test of Structural Model for Fear of Crime in Social Networking Sites
Authors: Lee Seong-Sik , Choi Kyung-shick , Choi Sinyong , Englander Elizabeth
Published: July 2021

This study constructed a structural model which consists of social demographic factors, experience of victimization, opportunity factors, and social context factors to explain the public’s fear of crime on social networking sites (SNS). The model is based on the risk interpretation model, which predicts that these factors influence users’ fear of crime victimization. Using data from 486 university students in South Korea, an empirically-tested model suggests that sex and age have direct and significant effects on fear of victimization, supporting the vulnerability hypothesis. Among opportunity factors, the level of personal information and the number of offending peers have significant effects on fear of victimization through the medium of the perceived victimization risk, although the effect of SNS usage time is not significant. In addition, it was revealed that experience of victimization has a direct effect on fear of victimization. Furthermore, findings indicate that bridging social network has a direct and indirect positive effect on fear of victimization, and collective efficacy has an indirect effect on fear of victimization. Results show that incidents in SNS have the strongest effect on fear of victimization among various factors in this model without being mediated by the perceived victimization risk. Overall, this study supports a structural model for the fear of victimization.
Blockchain Security: Situational Crime Prevention Theory and Distributed Cyber Systems
Authors: Blasco Nicholas J. , Fett Nicholas A.
Published: July 2021

The authors laid the groundwork for analyzing the crypto-economic incentives of interconnected blockchain networks and utilize situational crime prevention theory to explain how more secure systems can be developed. Blockchain networks utilize smaller blockchains (often called sidechains) to increase throughput in larger networks. Identified are several disadvantages to using sidechains that create critical exposures to the assets locked on them. Without security being provided by the mainchain in the form of validated exits, sidechains or statechannels which have a bridge or mainchain asset representations are at significant risk of attack. The inability to have a sufficiently high cost to attack the sidechain while mainchain assets can be withdrawn, along with the disconnect between the integrity of the sidechain and the value of the stolen assets are among the top disadvantages. The current study used a vulnerability analysis and theoretical mathematics based on situational crime prevention theory to highlight the attack vectors and prevention methods for these systems. Much of the analysis can be applied to any distributed system (e.g. blockchain network), particularly any supposedly trustless off-chain component. The equations developed in the current study will hold for any two chains that are bridged and pass value back and forth and provides evidence to suggest a public sidechain is likely not a viable option for scalability due to security concerns. Criminal strategies on blockchain networks in the digital realm are similar to criminal strategies in the physical realm; therefore, the application of criminology can lead to more efficient development and ultimately more effective security protocols.

Published: July 2021

Background: Stroke is the sudden loss of neurological function which is caused by an interruption of blood flow to the brain. A variety of focal deficits are possible that include changes in level of consciousness and impairments of sensory, motor, cognitive, perceptual and language functions. Trunk muscles are impaired in the patients with stroke so there is diminished ability to maintain balance because of weakened muscle strength of trunk. Resistance to neck motion during PNF provides irradiation to the trunk muscles.
Purpose: The purpose is to study the scientific evidences regarding the effect of proprioceptive neuromuscular facilitation neck pattern exercises on balance in stroke.
Methodology: A search for relevant articles was carried out using key words- Neck proprioceptive neuromuscular facilitation, Balance, Trunk control and Stroke. Search engines used were Google Scholar, PubMed, PEDro, ScienceDirect and ResearchGate. Studies were selected from year 2011-2020. Eight studies were included in which there were 6 randomized control trial, 1 case series, 1 single subject design.
Results: All the 8 articles concluded that proprioceptive neuromuscular facilitation neck pattern exercise is effective in improving balance in the patients with stroke. (level of evidence :1b,2a,4,5)
Conclusion: Based on evidences, it can be concluded that proprioceptive neuromuscular facilitation neck pattern exercise is found to be effective in improving balance in the patients with stroke.
Clinical Implication: Proprioceptive neuromuscular facilitation neck pattern exercises can be used as an adjunct to other treatment in improving balance in stroke.

Моральный реализм как концепция обоснования морали
Authors: Прокофьев Андрей Вячеславович
Published: July 2021

Автором проведена реконструкция и оценены перспективы теории ненатуралистического морального реализма в качестве подхода к обоснованию морали. Под обоснованием морали понимается выдвижение аргументов, которые способны успешно противостоять сомнению во всеобщей обязывающей силе моральных требований. В свете ненатуралистического морального реализма нравственные требования признаются людьми в качестве требований разума, который фиксирует моральные факты. Простейшая (интуитивистская) форма ненатуралистического морального реализма предполагает наличие у человека непосредственной интуитивной способности, которая раскрывает ему в самом общем виде моральные обязанности перед другими людьми. Этот вариант уязвим для критики, опирающейся на демонстрацию «странности» той картины мира, которая стоит за ним, и на одну из сторон дилеммы Причарда. Более сложная (конструктивистская) форма ненатуралистического морального реализма обходит подобную критику с помощью такой интерпретации моральных фактов, которая позволяет обнаружить фундаментальное различие между ними и теми фактами, с которыми имеет дело естествознание. Однако сторонники данного подхода вынуждены прибегать для обоснования морали к тезису о том, что любые ценностные суждения обладают «встроенной чувствительностью» к моральным требованиям. Этот вывод превращает конструктивистские концепции из реалистических в эвдемонистические; делает их уязвимыми для двух аргументов против эвдемонистического обоснования морали.

Background and aims: Branched chain amino acids (BCAAs) can be tightly connected to metabolism syndrome (MetS) which can be counted as a metabolic indicator in the case of insulin resistance (IR). The aim of this study was to assess the potential role of these acids under oxidative stress. Material and Methods: the in vitro antioxidant activity of BCAAs was assessed using free radical 1, 1-diphenyl-2-picryl-hydrazyl (DPPH) scavenging assays. For further check, a qRT-PCR technique was madefor detection the extent of alterations in gene expression of antioxidative enzymes (catalase and glutathione peroxidase (Gpx)) in lipopolysaccharides (LPS(-induced macrophages RAW 264.7 cell line. Additionally, BCAAs antioxidant activity was evaluated based on plasma H2O2 levels and xanthine oxidase (XO) activity in prooxidative LPS-treated mice. Results: Different concentrations of BCAAs affected on DPPH radical scavenging activity but to lesser extent than the ascorbic acid. Besides, BCAAs obviously upregulated the gene expression levels of catalases and Gpx in LPS-modulated macrophage RAW 264.7 cell line. In vivo BCAAs significantly minimized the level of plasma H2O2 as well as the activity of XO activity under oxidative stress. Conclusion: our current findings suggest that BCAAs supplementation may potentially serve as a therapeutic target for treatment of oxidative stress occurs with atherosclerosis, IR-diabetes, MetS and tumorigenesis.

Published: July 2021

Background: Tuberculosis is the oldest common infectious disease affecting not only lungs but several organs in a human body. Its caused by the bacteria Mycobacterium tuberculosis. Tuberculosis exposure is through lungs. This disease has co-morbid conditions. The basic treatment according to WHO is with Isoniazid, Rifampicin, Pyrazinamide, Ethambutol, but these drugs may lead to adverse drug reactions and drug interactions. Objective: To determine the adverse effects and drug-drug interactions post administration of anti-tubercular drugs and to determine the influence of drugs on their co-morbid conditions of patients suffering from tuberculosis in Aster Prime Hospital. Methods: The patient’s prescriptions of total 110 were collected from the outpatient and in-patient Pulmonology department. These were noted in the data collection form and the comparative study was done by evaluating the number of male and female affected with Tuberculosis, common drug-drug interaction with respective drug, adverse drug reaction followed by the common co-morbid condition occurring with TB and the effect of drugs on co-morbidities Results: The prevalence of tuberculosis in 110 patients was found to be more in females by 12% than males. The co-morbid conditions found with tuberculosis were Hypertension, diabetes, pleural effusion, hepatitis, cavitary disease and respiratory failure. The least common comorbidities were chronic obstructive pulmonary disease (COPD), gastritis, and stroke and chronic kidney disease (CKD) and ulcerative colitis. The total adverse effect found in the 62 patients (56.36%) and the patients with no adverse drug reactions were 48 (43.63%) The percentage of total drug-drug interactions found in the patients were 44% (n=48) and the percentage of patients with no interactions were 56% (n=62). Conclusion: Health care workers play an important role and considered as a vital group for tuberculosis awareness activities to increase competence in TB management and compliance with national guidelines. Interventions address a combination of varying influences on behaviour, focusing on specific gaps identified to improve their impact.

One of the widely efficient and noteworthy nanocarriers that could draw a great attention toward pharmaceutical fields is nanoemulsions (NEs). NEs are thermodynamically stable colloidal dispersions composed of two immiscible liquids, oil and water that mixed together using emulsifying agent (surfactant and co-surfactant). It regarded as pharmaceutical dosage form having droplet size within a nanometer range, hence it has extensively considered as carrier for delivering active agents. Such carrier is fabricated in order to overcome some obstacles associated with conventional drug delivery systems especially low bioavailability. The objective of this review is to present an overview about NE and its latest applications in diverse areas such as drug delivery, cosmeceutical and nutraceutical. Clarifications about different mechanisms of NEs development that are frequently used were provided. Correspondingly, popular characterization techniques for NEs such as determination of particle size, polydispersity index (PDI), zeta potential and viscosity were reviewed. Eventually, summary of physical and chemical instability in addition to the regulatory aspects of NE were provided.

Multicultural education is the process of developing all human potential that respects their plurality and heterogeneity as a consequence of cultural, ethnic, ethnic, and religious (religious) diversity. Multicultural education emphasizes a philosophy of cultural pluralism into the education system based on the principles of equality, mutual respect and acceptance as well as understanding and a moral commitment to social justice. Multicultural education begins with the development of ideas and awareness about interculturalism after World War II.The emergence of interculturalism ideas and awareness is not only related to the development of international politics regarding human rights, independence from colonialism, racial discrimination, etc., also because of the increasing plurality in Western countries themselves as a result of increased migration from newly independent countries to America and Europe. Multicultural education is actually a caring attitude and want to understand (difference) or politics of recognition of political recognition of people from minority groups. Multicultural education looks at society more broadly. Based on the basic view that indifference and non-recognition are not only rooted in racial structural inequality, but the multicultural education paradigm includes subjects regarding injustice, poverty, oppression, and underdevelopment of minority groups in various fields: social, cultural, economic, education , and so forth.The purpose of Islamic education is not limited to filling students' minds with science and subject matter, but to cleanse their souls which must be filled with good character and values and be conditioned so that they can live their lives well. This is in accordance with the objectives of multicultural education, which is to create a harmonious life in a pluralistic society. As a country with a very diverse cultural, ethnic, linguistic andreligious background, Indonesia needs a strategic approach and instrument that can be used as a national movement to realize the unity, unity and integrity of the nation in order to become a sovereign and dignified nation. One of the instruments of its approach is through multicultural education.Multicultural education is a progressive approach to transforming education that holistically provides criticism and shows weaknesses, failures and discrimination in education. Multicultural education as an instrument of social engineering encourages schools to play a role in instilling awareness in multicultural societies and develop tolerance and tolerance to realize the needs and abilities to work with all the differences that exist.The practice of multicultural education in Indonesia can be implemented flexibly, not necessarily in the form of separate or monolithic subjects. The implementation of multicultural education is based on five dimensions: (1) content integration, (2) the process of compiling knowledge, (3) reducing prejudice, (4) equal pedagogy, and (5) school culture and empowering school structures.

On the Steady State Motions Control Problem for Mechanical Systems with Relay Controllers
Authors: Andreev Aleksandr , Peregudova Olga
Published: July 2021

The paper presents the solution to the stabilization problem of steady state motions for a holonomic mechanical system by using relay controllers. This solution is achieved by proving new theorems on the asymptotic stability of the solution to a differential equation with a discontinuous right-hand side. The novelty of the theorems is based on the limiting inclusions construction and the use of semidefinite Lyapunov functions. As an example, the stabilization problem of steady-state motion for a five-link robot manipulator is solved by using relay controller.
On the Nonlinear Observability of Polynomial Dynamical Systems
Authors: Gerbet Daniel , Röbenack Klaus
Published: July 2021

Controllability and observability are important system properties in control theory. These properties cannot be easily checked for general nonlinear systems. This paper addresses the local and global observability as well as the decomposition with respect to observability of polynomial dynamical systems embedded in a higher-dimensional state-space. These criteria are applied on some example system.
“Rosa o azul”
Authors: Valdez Espinoza Carlos
Published: July 2021

Los colores siempre han sido motivo de atención por diferentes estudiosos, especialistas y disciplinas, e interpretados desde diferentes épocas, contextos y culturas. Sin embargo, hoy en día se vinculan determinados colores al género de manera muy generalizada, por ejemplo, si nace un niño o niña se activa la lógica azul o rosa respectivamente para adquirir o entregar todo tipo de productos infantiles con estas tonalidades. Esto genera lo que Foucault denomina disciplinar los cuerpos, en este caso, mediante los colores. El presente trabajo realiza una breve revisión de algunas concepciones y estudios sobre el color; luego mira las relaciones entre el cromatismo y la representación de las identidades de sexo y género. Parte de los carteles usados por el colectivo “Con mis hijos no te metas” y desarrolla análisis visuales de artefactos culturales locales de diferentes épocas, con el fin de problematizar el vínculo entre los colores y la afirmación o representación de determinadas identidades.

Dos amistades neobarrocas
Authors: Lizardo Méndez Gonzalo
Published: July 2021

El presente artículo resultado de investigación reflexiona sobre dos (2) amistades intelectuales: cuatro (4) creadores cuyas colaboraciones recíprocas ayudan a elucidar esa tradición cultural que algunos pensadores localizan en Hispanoamérica y califican de “barroca”. Por un lado, la honda amistad entre María Zambrano y José Lezama Lima delata la urgencia de forjar —por medios filosóficos y poéticos— una teología sincrética más adecuada para nuestro paisaje. Por el otro, la breve relación entre Eugenio D’Ors y Pablo Picasso elucida la importancia de lo fugaz y lo lúdico para la creación artística pero también para la crítica filosófica. Así, al confrontar esas dos (2) amistades, será posible intuir con mayor claridad la función del arte y la figura del artista en nuestros tiempos neobarrocos.
