Recorrido bibliográfico de un vocablo “vagabundo”
Authors: Simón Ruiz María Cristina
Published: July 2022

La palabra chingar y sus derivados son palabras altamente productivas en el uso –positivo y negativo– coloquial, popular y vulgar de la comunicación cotidiana en México. Sin embargo, no hay todavía un consenso sobre su etimología, ni en los diccionarios, ni entre los filólogos que se han dado a la tarea de dilucidarla, así que la intención de esta comunicación es presentar un recorrido bibliográfico comparativo por algunas de las obras más importantes que han abordado el tema. Por una parte, a través de diferentes diccionarios, como el de Carlos Gagini, Diccionario de costarriqueñismos, de 1919; por otra, a lo largo de las opiniones de ciertos filólogos y lexicólogos que apoyan diferentes orígenes, como Fernández Ferraz (nahuatlismo), Salado Álvarez (gitanismo) o Luis Fernando Lara (africanismo subsahariano). Estos recorridos se ubican a partir de la segunda mitad del siglo XIX, tras el advenimiento de las independencias hispanoamericanas.
Carga aérea y crecimiento económico en las entidades federativas de México 1992-2019
Authors: Cruz Rodriguez Ignacio Javier
Published: July 2022

El presente análisis busca examinar la relación causal entre la carga transportada vía aérea y la actividad económica de las entidades federativas en México. Para tal fin, se usaron pruebas de cointegración de Pedroni/Johansen, seguidas de pruebas de Granger para analizar el largo plazo y Wald para el corto, así como un modelo de corrección de errores (VECM). El análisis se llevó a cabo para el total de la carga y se dividió, por un lado, en carga doméstica y, por otro lado, en carga internacional. Los resultados obtenidos sugieren la existencia de equilibrio de largo plazo y bidireccionalidad cuando se agrega toda la carga, aunque al desagregarla las causalidades se vuelven unidireccionales. Se discuten los resultados a la luz de posibles políticas públicas.

Learning to Survive using Reinforcement Learning with MLAgents
Authors: Dandoti Sarosh
Published: July 2022

Abstract: Simulations have been there for a long time, in different versions and level of complexity. Training a Reinforcement Learning model in a 3D environment lets us understand a lot of new insights from the inference. There have been some examples where the AI learns to Feed Itself, Learns to Start walking, jumping etc. The reason one trains an entire model from the agent knowing nothing to being a perfect task achiever is that during the process, new behavioral patterns can be recorded. Reinforcement Learning is a feedback-based Machine Learning technique in which an agent learns how to behave in a given environment by performing actions and observing the outcomes of those actions. For each positive action, the agent receives positive feedback; for each negative action, the agent receives negative feedback or a penalty. A general simple agent would learn to perform a task and get some reward on accomplishing it. The Agent is also given punishment if it does something that it’s not supposed to do. These simple simulations can evolve, try to use their surroundings, try to fight with other agents to accomplish their goal

Study the Comparative Effect of Different Link Dampers on G+25 High Rise Buildings in Seismic Zone IV
Authors: Yadav Rajat
Published: July 2022

Abstract: The usefulness of a high-rise building equipped with different types of link dampers (such as bilinear dampers, fluid viscous dampers, and frictional dampers) for the purpose of controlling seismic vibration is discussed in this study. Due to their safe, efficient, and cost-effective design, dampers have gained a lot of popularity in recent years for the purpose of controlling vibration in structures. They are frequently employed in structural vibration control to reduce seismic risks and, with the use of passive energy dissipation devices, can enhance the dynamic responsiveness of both new skyscrapers and existing high-rise structures. The structure's structural safety and serviceability are improved, and the controlling devices stop the building from collapsing during an earthquake, thereby greatly reducing damage. This paper would discuss the high rise RCC structures (G+25), with different Link dampers for seismic vibration control and study the effect of dampers on it using ETABS software.
Clinical Decision Making using Machine Learning
Authors: N C Danushri
Published: July 2022

Abstract: Deaths due to cardiovascular diseases are increasing at an alarming rate. This led to nearly 2.1 million deaths in India in 2015. Heart disease is one of the deadliest causes of death worldwide and has a major impact on the lives of rural people. According to a recent study, cardiovascular disease mortality among rural Indians has surpassed urban Indians. Such numbers are alarming, especially when 68% of India's population lives in rural areas that have poor access to quality healthcare. This paper aims to provide a solution to this problem by introducing a new model*clinical*decision*support system*, abbreviated as CDSS, which*includes machine learning algorithms for the diagnosis of cardiovascular diseases. CDSS is intelligent enough to diagnose a patient's*disease* and help the doctor prescribe the*correct medication, reducing the cost and effort required to prescribe unnecessary treatment. *In this work, we applied correlation-based feature selection (CFS) and a multilayer perceptron classifier on a large heart disease dataset. The dataset used in this study is the "Cleveland Clinic Foundation Heart Disease Dataset" available at the UCI Machine Learning Repository. Our proposed model produced greater accuracy compared to other existing models used in this study. This system can be integrated into a public health care setting to help rural people get a correct, timely and cost-effective diagnosis.

Neural Machine Translation
Authors: Rahul Kodithala
Published: July 2022

Abstract: The project's novelty is not merely importing modules and preparing data and feeding the data to the model but understanding how the real language translation works and implementing the logics underlying each method utilized and creating every function from scratch, resulting in the creationof a Neural Machine Translation model. Initially, translation was accomplished by simply substituting words from one language for those from another. However, because languages are essentially different, a greater degree of knowledge (e.g., phrases/sentences) is required to achieveeffective results. With the introduction of deep learning, modern software now employs statisticaland neural techniques that have been shown to be more effective when translating. We are essentially translating German to English utilizing Sequence to Sequence models with attention and transformer models. Of course, everyone has access to Google Translates power, but if you want to learn how to implement translation in code, this project will show you how. We are writingour code from scratch, without using any libraries,in order to understand how each model works.While this design is a little out of date, it is still a great project to work on if you want to learn more about attention processes before moving on to Transformers. It is based on Effective Approaches to Attentionbased Neural Machine Translator and is a sequence to sequence (seq2seq) model for German to English translation.
Extract and Organize Information in Images with AI using IBM Services
Authors: C S Anu
Published: July 2022

Abstract: OCR is a short form of Optical character recognition or optical character reader. By the full form, we can understand it is something that can read content present in the image. Every image in the world contains any kind of object in it and some of them have characters that can be read by humans easily, programming a machine to read them can be called OCR. In machine learning, data mining is one of the major sections that cover the extraction of the data from the different platforms. OCR (Optical Character Recognition) is part of the data mining process that mainly deals with typed, handwritten, or printed documents. These documents hold the data mainly in the form of images. Extracting such data requires some optimised models which can detect and recognize the texts. Getting information from complex structured documents becomes difficult and hence they require some effective methodologies for information extraction. In this article, we will discuss OCR with IBM Watson Natural Language Understanding API, a deep learning-based tool for localizing and detecting the text in documents and images.

This system will mark attendance electronically and recorded attendance will be stored in a database. The preparation of a question paper for the Internal Assessment Exam can be automatically generated with the help of teachers according to RBT levels. The Internal Assessment is very important for students. This system will give individual student reports based on the performance of student in internal assessment, exactly in which type of RBT level the student need to improve themselves.
E-Voting System Using Homomorphic Encryption
Authors: Neeli Dr. Jyoti
Published: July 2022

Abstract: A protected e-voting system using Blockchain technology is proposed in this paper. It is using homomorphic encryption casting a vote electronically. It is represented that in spite of the fact that blend-based casting a ballot is an extremely straightforward answer for special e-casting a ballot it is helpless against an intimidation threat from politically contesting individuals. The intimidation assault particularly goes after special e-casting a ballot plot just results the political decision result and uncovers no vote, so is safe to the assault. Homomorphic encryption calculation is taken advantage of not just to count the votes without uncovering them yet in addition to change the votes when another round of counting is required. Additionally, it accomplishes all the security properties normally wanted in e-casting a ballot. Since Blockchain technology is used to store the votes any sign of tampering will be easily detected with the discrepancy of the time signatures and the hash values. The proposed will enable the citizen or a voter entity to vote from the confines of their home thereby negating their travel expenses which would otherwise be too extreme if the voter entity resided in a place where there is no adequate infrastructure to support traditional voting schemes. The voter entity can first verify their identity and receive an OTP which then enable them to cast a vote online in a dedicated web application.

Repression of CB1 receptor gene expression caused by dysfunctional microRNAs contributes to simvastatin-induced skeletal muscle cell toxicity
Authors: Kalkan Hilal , Panza Elisabetta , Pagano Ester , Ercolano Giuseppe , Moriello Claudia , Piscitelli Fabiana , Capasso Raffaele , Marzo Vincenzo Di , Iannotti Fabio
Published: July 2022

Background and Purpose Statins are the most common prescribed
lipid-lowering agents worldwide. Although their use is generally safe,
statins cause muscle disorders in 1 in 10.000 people. In this study, we
investigated the role of the endocannabinoid system (ECS) in
statin-induced myotoxicity. Experimental Approach ECS activity was
evaluated in murine C2C12 and primary human myoblasts exposed to
simvastatin (30 µM) as well as in skeletal muscles of C57BL/6J mice
receiving oral simvastatin (20 mg kg−1) for three weeks using LC-MS,
qPCR and western blot analyses. Bioinformatic, genetic and
pharmacological tools followed by qPCR and FACS analyses, were used to
explore the role of the cannabinoid CB1 receptor. Key Results In C2C12
cells, simvastatin caused dysregulation in levels of the two major
endocannabinoids 2-AG and AEA as well as upregulation of miRNAs, mostly
miR-152, which repress the expression of the endocannabinoid receptor,
CB1. Notably, simvastatin-induced toxicity in myoblasts was exacerbated
in the presence of the selective CB1 antagonist rimonabant, and slightly
attenuated by the CB1 positive allosteric modulator GAT211. In
antagomiR-152-transfected C2C12 myoblasts, simvastatin toxicity was
prevented along with the rescue of CB1 expression. Simvastatin caused
similar alterations in skeletal muscles of C57BL/6J mice, and most
importantly, in primary human myoblasts. Conclusions and Implications In
both murine and human skeletal muscle cells, simvastatin induces changes
in ECS activity also caused by dysregulation of specific miRNAs inducing
repression of CB1 expression. In sum, we propose a novel mechanism to be
targeted for preventing statins-induced myopathy.
Correlations of morpho-agronomic traits and forage quality properties in diverse red clover (Trifolium pratense L.) collections
Authors: Radinovic Irena , Vasiljevic Sanja , Brankovic Gordana
Published: July 2022

Red clover is an important perennial fodrage legume and a rich source of
highly nutritional voluminous forage for livestock feed, which is
continuously improved by plant breeding efforts that rely significantly on
trait correlation studies. A two-year field trial was conducted at Rimski
Sancevi, Novi Sad, Serbia. The aim of this research was to assess
correlations of important morpho-agronomic traits and forage quality
properties of 46 red clover accessions of diverse origins. The highest
Spearman?s correlation coefficient (0.97, p<0.01) was found between the
branch number and internode number per stem in the first experimental year.
The green mass yield and the dry matter yield in both years had very high
(0.95, p<0.01) and high (0.86, p<0.01) correlations, respectively. The stem
height and internode number per stem had intermediate correlations in both
years (0.68, p<0.01, and 0.50, p<0.01, respectively), and stem height
exhibited an intermediate correlation with green mass yield (0.57, p<0.01,
and 0.62, p<0.01, respectively) and dry matter yield (0.60, p<0.01, and
0.56, p <0.01, respectively) in both years. Thus, the indirect selection for
higher plants with higher numbers of internodes per stem may contribute to
accomplishing higher yield performance per plant. Although the branch number
showed the highest positive correlation (p<0.01) with internode number per
stem and an intermediate positive correlation (p<0.01) with stem height,
this trait had a low correlation with green mass yield and dry matter yield
and cannot be used as a criterion for indirect selection.

Integral transformations have been used for a long time in the solution of
differential equations either solely or combined with other methods. These
transforms provide a great advantage in reaching solutions in an easy way
by transforming many seemingly complex problems into a more understandable
format. In this study, we used an integral transform, namely Kashuri Fundo
transform, by blending with the homotopy perturbation method for the
solution of non-linear fractional porous media equation and time-fractional
heat transfer equation with cubic non-linearity.

In this study, heating performances of horizontal and vertical earth-air heat
exchangers with equal pipe lengths were evaluated in ANSYS FLUENT 19.2
simulation program based on CFD for the winter period of Bitlis, Turkey.
Thermal per?formance analyses regarding vertical and horizontal 3-D-modeled
earth-air heat exchangers were evaluated in steady-state condition of the
simulation program for different values of Re = 5?103, 104, 2?104, 4?104,
6?104, 8?104, and 105 numbers by using standard k-? turbulence model.
Numerical results obtained from CFD based simulation program were compared
with a numerical study in the literature, and it was determined that there
was a consistency between the results. The pressure loss and fan power
values of horizontal and vertical earth-air heat exchangers were also
investigated in addition their thermal performances. A good agreement was
found between the pressure loss values obtained from the theoretical and
simulation calculations of both earth-air heat exchangers. Considering the
temperature increases in both earth-air heat exchangers, the highest and
lowest temperature increases were observed in vertical earth-air heat
exchanger with 22.52 K and 10.67 K, respectively. The best thermal
performance was observed in vertical earth-air heat exchanger for 5?103,
104, and 2?104 values of Reynolds number and in horizontal earth-air heat
exchanger for 4?104, 6?104, 8?104, and 105 values of Reynolds number.
Changing Hearts and Minds: Evidence from a Symposium on Diversity, Equity, and Inclusion
Authors: Booker Danielle , Cook Kirsten A. , Wu Yi-Jing
Published: July 2022

The accounting profession and academic institutions have expressed solidarity with diversity, equity, and inclusion (DEI) principles and recognize the importance of DEI programs in pedagogy to enhance students’ and new accounting professionals’ awareness of DEI issues specifically related to race. However, despite the collective acknowledgement by the accounting profession and academic institutions regarding the importance of DEI, no research, to our knowledge, in business or accounting higher education literature has empirically evaluated the effectiveness of specific DEI programming for enhancing students’ awareness of and attitudes toward racial issues. We fill the gap by investigating the effectiveness of a diversity symposium and a reflective writing exercise on undergraduate accounting students’ awareness and attitudes regarding racial issues. Our results suggest that both pedagogical interventions incrementally improve students’ knowledge and understanding of these issues. Our results have important implications for accounting higher education by providing implementable methods to enhance student awareness and attitudes.
Integrating Data Analytics into the Accounting Curriculum: Faculty Perceptions and Insights
Authors: Losi Heather J. , Isaacson Elena V. , Boyle Douglas M.
Published: July 2022

Over the past decade, many stakeholder groups have explored how to integrate data analytics into the accounting curriculum. This study expands that literature by surveying 321 accounting faculty regarding their perspectives on the effectiveness of data analytics implementation. We examine curriculum development, course assessment, students' abilities, and faculty skills to design and teach such courses. We identify specific gaps in the accounting curriculum where further data analytics integration may be considered. We find several challenges to integration and support for infusing analytics skills earlier in the accounting curriculum. Accounting departments should consider the expertise of their faculty, especially assistant professors, who seem to have more knowledge of data analytics than any other rank, and focus on implementing specific data analytics skills throughout the accounting curriculum. We also provide proposed action items that will help accounting departments evaluate curriculum and related resource requirements.

With the growth of greenhouse gases in the atmosphere, renewable energies have become a promising solution to reduce global warming and pollution. One of the government’s goals is to introduce renewable energy in all sectors, especially the agricultural sector, which relies heavily on fossil fuels to operate milking cooling systems and other systems. This article presents a real study on the feasibility and efficiency of Grid connected PV system on a dairy farm, in Tlemcen province. It’s a typical farm that consumes about 42MWh / year of electrical energy. On this basis, we will dimension the system using the HOMER software, to feed this farm. A Grid connected PV system of 30W could produce 54.03MWh/yr, with Renewable Fraction of 53%, and 28.54kWh/yr was generated from the PV array, and 25.44kWh/yr is the amount of electricity purchased by the grid, while, the energy injected into the grid was estimated at 8.430 MWh/yr. In order to show the feasibility of this system we will proposed another system based on diesel generator, so that we can economically compare between the two systems, the lowest net present cost (NPC) of Diesel system of 25kW was estimated at 826$, with a cost of energy (COE) of 1.51$/kWh, while, the highest net present cost (NPC) of PV-Grid system (40kW) is 233$, and the cost of energy (COE) is 0.42$/ kWh. Therefore, this study shows the effectiveness of the grid-PV system in economic and environmental terms, thus, the use of this system in most dairy farms in Algeria contributes to the development of national agricultural production.

Ophiocordyceps is special type of entomopathogenic fungi which well known to infect insects and turning them into zombie. A total of 250 species have been described from its genus, and some are known to control their hosts, which are most notably ants. They are ubiquitous within tropical rain forests across the board, with few publication reports from temperate ecosystems. These fungal pathogens possess the capacity to manipulate host behaviour in order to increase their own ﬁtness. These entomopathogenic fungi cause their hosts frezee to die in an exposed area on the abaxial surface of leaves or branches, which then enhancing the fungus spore production and dispersal. Despite the high diversity of fungi and insect with vast tropical forest as well as drugs potency from Ophiocordyceps, publication of Ophiocordyces was rarely reported from Indonesia. This review will explain the evolution of Ophiocordyceps-insect interaction, simbiont distribution, and zombie-insect formation mechanism, in order to induce zombie-insect research in Indonesia.

Nowadays, Urban Heat Island (UHI) occurs in big cities worldwide. The UHI phenomenon needs to be introduced in school because this phenomenon occurs around the students. Surakarta, one of the big cities in Indonesia, has been threatened by the UHI phenomenon, so enrichment materials related to the UHI phenomenon are needed for students in schools. This research will develop the UHI e-module as an enrichment teaching material on the impact of global climate change and research on climate and its utilization. This paper aims to present an e-module development research methodology on UHI based on the phenomenon of UHI threats in Surakarta City and its effect on student achievement and collaboration skills. Design and Development Research (DDR) uses the Borg and Gall model. The methodology of the research development is divided into three phases: the needs analysis phase, the design and development phase, and the implementation and evaluation phases. The difference in this research is the geographical space-based study approach in the development of material based on the UHI phenomenon in Surakarta City and urban and rural spatial sampling techniques.
Tracing proof schemes: some patterns and new perspectives
Authors: Yılmaz Akkurt Yasemin , Durmuş Soner
Published: July 2022

The aim of this paper is to review some studies conducted with different learning areas in which the schemes of different participants emerge. Also it is about to show how mathematical proofs are handled in these studies by considering Harel and Sowder's classification of proof schemes with specific examples. As a result, it was seen that the examined studies were addressed in the learning areas of Analysis, Geometry, Algebra, Linear Algebra, Elementary Number Theory, Probability, Combinatorics, and MIX. Students in early grades tend more towards external and empirical proof schemes. On the other hand, the characteristics of the proof schemes become more sophisticated as the participants' profiles change to pre-service teachers or as they become more specializing in mathematics. Some results are as follows: the academic achievement levels, genders, and grade levels of the participants in the studies examined in this paper have indicated that they have similar traces with the schemes they use. In addition, it has been determined that new perspectives such as examining Harel and Sowder's classification with new lenses, revealing the overlooked roles of some dynamics in proof, or improving the framework provide an important research area in terms of revealing students' potentials.

Authors: Dawoud Husam , Daher Wajeeh
Published: July 2022

This research aimed to analyze Algebra unit in both the old and new Palestinian curriculum for the ninth grade by using deductive content analysis based on the social semiotic approach. The results of this study showed that, in both books, the mental, behavioral, and verbal processes were more frequent than the relational, existential, and material processes. Moreover, the most frequent object used in both curriculum were the initial description, the rule, and the official definition. The most frequent representation of the mathematical object in both curriculum, was the algebraic representation, then the verbal, the numerical and the graphic representations. The research findings also indicate that in both books, the use of the pronoun “I” was the most frequent, then the pronoun “we” and then other pronouns. The imperative was frequent in the Algebra unit in the old curriculum, but less frequent in the new curriculum. The research findings, regarding the textual function in both books, indicated that the text orientation ‘previous knowledge to new knowledge’ was the most frequent in Algebra. This demonstrates that the author in both books cared about applying the new knowledge and assessing it, what means that the text progresses horizontally in both curriculum.
