In this paper, we have performed a closed-form calculation of the radiation pattern of a base station antenna by using Ad Hoc Bessel-Fourier expansion. Once the coordinates system is fixed, we proceed to derived the magnetic potential vector underlining the complex part which is subsequently expanded in a Bessel-Fourier series. Since the radiation intensity is proportional to the square of the polar component of electric field, we used the well-known relation vec{E} \approx \vec{\nabla}\times \vec{\nabla} \times \vec{A} It gives capabilities to apply antenna data to the resulting closed-form expression for obtaining numerical estimations of the possible exposure levels. For this end, we measured the specific absorption radiation (SAR) to evaluate and discard possible effects of contamination by antenna radiation in the vicinity of the emission source. For a source of 2.0 GHz and 1.5 Vm-1...

This work was carried out by the importance of providing insights into the nano-based drug delivery of anticancers. To this aim, a representative model of aluminum nitride (AN) nanocage scaffold and two of its boron and gallium doped forms (BAN and GAN) were investigated towards the adsorption of thiotepa (Tep) anticancer. Density functional theory (DFT) calculations were performed to evaluate the stabilized structures and their corresponding electronic features. The results indicated the contribution of N-head and S-head of Tep to interactions with each scaffold resulting six complexes; NTep@AN and STep@AN, NTep@BAN and STep@BAN, NTep@GAN and STep@GAN. In each complex model, the characteristic features were obtained based on the interactions details and frontier molecular orbitals related features. In this regard, the investigated scaffolds were found suitable for adsorbing the Tep subs...

The video game industry has undergone one of the most significant transformations in recent times. This is reflected not only in the economic aspect but also in the increasing number of players who want to explore and interact in the world of video games in recent years. As for the Real-Time Strategy (RTS) genre, which reached its peak in the early 2000s, it did not continue to see the same trend in game development, and the population of active players has been declining [1]. The primary reason for this continuous decline is the competition from games in other genres such as First Person Shooter (FPS), Multiplayer Online Battle Arena (MOBA), and other genres with attractive characteristics that set them apart. In response to this, a solution is offered, which involves the development of a multiplayer RTS video game for Windows operating systems (PC), with the aim of generating greater i...

The present work reports the successful synthesis of a novel Pb2+ ion-imprinted polymer (Pb-IIP) based on a rhodizonate-like selective ligand by precipitation. Three functional monomers, namely acid acrylic (ACRY), 2-acrylamido-2-methylpropane sulfonic acid (AMPSA) and allylamine (ALLY), were chosen by computer simulation using density functional theory (DFT). The materials obtained were applied for the selective removal of Pb2+ from aqueous solutions and were characterized by Fourier transform Infra-red (FTIR), scanning electronic microscopy (SEM) and flame atomic absorption spectrometry (FAAS). The results obtained from the adsorption experiments performed under optimal conditions were in good agreement with the computational design and showed that IIP-AMPSA exhibited a relatively higher adsorption capacity for Pb2+ (51.84 mg g?1) than IIP–ACRY (31.02 mg g?1) and IIP-ALLY (12.90 mg g...

Sensing drug substances by nanostructures are very important in accordance with the management of targeted drug delivery processes and drug substances detections. Boron nitride (BN), aluminum nitride (AlN), and gallium nitride (GaN) decorated carbon cage (BN-C, AlN-C, and GaN-C) scaffolds were assessed towards sensing the thiamazole (TMZ) drug through the wB97XD/6–31 + G* level of density functional theory (DFT) computations. The singular models were optimized and their combinations to each other were stabilized to obtain the interacting TMZ@Scaffold bimolecular complexes and their corresponding features. The results indicated the existence of non-covalent physical interactions between the substances and their electronic features indicated possibility of sensing function for the investigated scaffolds. Based on the variations of values of adsorption energy and energy gap, the features ...

Purpose: The aim of this article is to establish a theoretical-methodological proposal to study discursive interactivity from a multidisciplinary perspective different from the traditional structural and quantitative media research. The sociological definition of interaction and the basis of discourse analysis –as a theoretical discipline and scientific method– are assumed to propose a concept of interactivity that addresses the double materiality of the term: as a structure and a process. Methodology: Grounded theory becomes a methodological strategy and is complemented by the bibliographic-documentary method and discourse analysis. By means of theoretical sampling, codification, constant comparison and theoretical saturation, a category is determined that emerges as central, for which the following are established: conceptual definition, dimensions, subcategories and indicators. Re...

Natural Language Processing deals with the understanding and generation of texts through computer programs. There are many different functionalities used in this area, but among them there are some functions that are the support of the remaining ones. These methods are related to the core processing of the morphology of the language (such as lemmatization) and automatic identification of the part-of-speech tag. Thereby, this paper describes the implementation of a basic NLP toolkit for a new language, focusing in the features mentioned before, and testing them in an own corpus built for the occasion. The obtained results exceeded the expected results and could be used for more complex tasks such as machine translation.

The use of computational methods that allow us to perform characterization on new compounds is not a novelty; nevertheless, the degree of complexity of the structures makes their study more challenging since new techniques and methods are required to adjust to the new structural model. The case of nuclear magnetic resonance characterization of boronate esters is fascinating because of its widespread use in materials science. In this paper, we use density functional theory to characterize the structure of the compound 1-[5-(4,5-Dimethyl-1,3,2-dioxaborolan-2-yl) thiophen2-yl] ethanonea by means of nuclear magnetic resonance. We studied the compound in its solid form with the PBE–GGA and PBEsol–GGA functionals, with a set of plane wave functions and an augmented wave projector, which included gauge in CASTEP and its molecular structure with the B3LYP functional using the package Gaussia...

Early mathematical competencies have a great impact on academic performance and on the development of more complex mathematical skills, especially in early education. Several authors have highlighted the importance of working memory and inhibition in the development of these mathematical skills; however, there is no agreement regarding the explanatory capacity of these executive domains with respect to differentiated performance in mathematics. The aim of this research was to evaluate the predictive capacity of verbal and visuospatial working memory and of behavioral and cognitive inhibition in mathematical competencies of relational logic and numerical type in 106 Chilean children of early education between 4 and 6 years old, who were evaluated with four executive tasks and an early mathematical assessment test. For data analysis, correlations and multiple linear regressions were perfor...

This article presents the inventory and analysis of two types of glyptographic expressions present in the temple Santa Ana of Yauri, capital city of Espinar province, Cusco: Masons’ marks and cruciform signs. The function of the marks is well determined as identification and accounting signs of the ashlars delivered by different stonecutters. The presence of the crosses is more intriguing because they do not seem to have an apotropaic function, and may rather be related to devotional expressions. It is evident that the Masons’ marks are older than the crosses and would have been engraved between the 17th and 18th centuries, during the construction of the original church, on whose remains the current building was built in the second half of the 19th century. Many of these lapidary signs have been affected by the scraping perpetrated during the restoration of the ecclesiastical complex...

En este trabajo se generaliza la aplicación del método perturbativo diferencial al análisis de sensibilidad en problemas de golpe de ariete para redes hidráulicas complejas y se analiza la función importancia. El fornalismo del método, en síntesis, consiste en formular un problema directo, su problema derivado y su correspondiente problema adjunto. El “problema directo” que tratamos es el fenómeno de golpe de ariete. Partimos de sus ecuaciones clásicas: la ecuación de momento (en la que se considera el término de fricción) y la ecuación de continuidad (en la que se considera el acoplamiento de la compresibilidad del fluido y la elasticidad de la tubería). Las condiciones de borde están dadas por las condiciones iniciales (en nuestro caso analizaremos un estado estacionario) y las condiciones de contorno (en las componentes hidráulicas). Las variables de estado (las va...

The sampling task of Seq2Seq models in Natural Language Processing (NLP) is based on heuristics because of the Non-Deterministic Polynomial Time (NP) nature of this problem. The goal of this research is to develop a quantum sampler for Seq2Seq models, and give evidence that Quantum Annealing (QA) can guide the search space of these samplers. The contribution of this work is given by showing an architecture to represent Recurrent Neural Networks (RNN) in a quantum computer to finally develop a quantum sampler. The individual architectures (i.e. summation, multiplication, argmax, and activation functions) achieve optimal accuracies in both simulated and quantum environments. While the results of the overall proposal show that it can either outperform or match greedy approaches. As the very first steps of quantum NLP, these are tested against simple RNN with a synthetic data set of random n...

Transmedia communication has achieved an important evolution and relevance in the last years, being considered by producers and organizations as a key strategy in the development of new projects, known through a diversity of media and platforms. At the same time, this process is influenced by a participative culture made up the prosumers. In this paper, we want to know how and what contribution brings the variety of media in the construction of transmedia worlds. Therefor it is planted as object of study the media ecosystem of Marvel´s Civil War; the comic began as a crossover and now it can be considered one of the transmedia storytelling more complete and complex cases in relation with the multiplicity of media involved.

In the age of the Internet, anonymous online users can form a societal reaction by posting large quantities of critique and insulting comments against (perceived) norm violations on social media. These so-called online firestorms, or Enjō in Japanese, tend to include aggressive behavior against the target. This research aims to reveal the dynamics of Enjō and explores how people communicate with each other in the formation process of Enjō by conducting a comparative case study. This study collects tweets posted in five Enjō cases and compares each case to create conceptual categories of the communication process of Enjō. Results show that the participants of Enjō interact with each other to define the problem of concern through exchange of information. Moreover, it is revealed that there are two types of process in the escalation of Enjō, “social problematization” and “villa...
