El poder de mercado de los hipermonopolios: evidencias y paradojas del capital monopolista en el siglo XXI
Authors:   Universidad Autónoma de Zacatecas, Caballero Anguiano Francisco Javier
Published: August 2022

Los monopolios representan la forma de organización emblemática del capitalismo de los siglos XX y XXI. Su capacidad de concentración y centralización de capital se ha acrecentado en tal dimensión que su poder ejerce influencia más allá de lo estrictamente mercantil y llega hasta la proporción macroeconómica. El propósito de este trabajo es analizar el poder de mercado del capital monopólico a partir del enfoque del Fondo Monetario Internacional (FMI), el organismo financiero internacional emblemático de la ortodoxia económica. Al respecto, se abordan algunas vertientes relevantes de la dinámica del capital monopolista y los pilares que la sustentan: el patentamiento, la innovación y la concentración de poder de mercado. La capacidad de incidir e inclusive de afectar negativamente al crecimiento de los países por la vía macroeconómica conduce hacia un nuevo terreno, más profundo e inquietante, donde el capital monopolista despliega su gran potencial devastador, el cual ya fuera definido con crudeza, si bien en otros términos, en la ley general de la acumulación capitalista de Marx, y que ahora se corrobora, involuntariamente, en el informe del FMI.
Bordeando el precipicio. ¿Puede el nuevo presidente izquierdista del Perú, Pedro Castillo, mantenerse en el poder?
Authors:   Universidad Ricardo Palma del Perú, Lust Jan , Cypher James Martin ,   Universidad Autónoma de Zacatecas
Published: August 2022

Al poco tiempo de su ascenso a la presidencia de Perú en 2021, Pedro Castillo, un maestro y sindicalista de izquierda, navega a contracorriente de la vieja élite de Lima y en general de la derecha que detenta la mayoría en el Congreso, que además de representar los intereses del gran capital, obstruyen el cambio social progresivo que propone el nuevo gobierno. Por si fuera poco, el gobierno que se erige sobre las ruinas del neoliberalismo, enfrentaba los saldos de la covid-19 que dejaron una alta mortalidad, la inflación y el aumento relativo de la pobreza. Sólo el Estado puede dirigir el cambio de la estructura productiva para una independencia económica, pero el cambio del modelo de desarrollo extractivo neoliberal se enfrenta a la férrea estructura de libre comercio y los condicionamientos del ajuste estructural. Si Castillo alcanzó la presidencia, el capital sigue controlando la estructura económica y el poder político. El clima de inestabilidad política y económica ha socavado la agenda progresista, y no presagia un punto de inflexión estructural, abrir espacios para atender demandas de campesinos y pobres urbanos, y reducir la depredación ambiental de la economía minera.
Há controvérsias! O estatuto fonológico das vogais nasais e a sua discussão na literatura
Authors: Teixeira Correa Bruna , Ferreira Gonçalves Giovana , Christine Seara Izabel
Published: August 2022

O presente artigo tem como objetivo fazer um levantamento dos principais trabalhos que discorrem sobre o estatuto fonológico das vogais nasais do português, bem como tecer reflexões acerca dos posicionamentos defendidos pelos autores. Existem, atualmente, três principais concepções acerca da natureza fonológica das vogais nasais do português: a bifonêmica, isto é, uma vogal oral seguida de uma consoante nasal (/VN/); a monofonêmica, ou seja, uma vogal nasal plena (/v͂/); e a bifonêmica composta por duas vogais, uma oral e outra nasal (/V+v͂/). O levantamento teórico e as reflexões realizadas mostraram que, independentemente da hipótese fonológica defendida e da perspectiva teórica de seus defensores, há argumentos passíveis de questionamentos, tendo em vista, especialmente, os avanços teóricos, tecnológicos e experimentais pelos quais tem passado a área nas últimas décadas.
Corp(o)ralidade dos sentidos: por um ensino da língua com historicidade no Ensino Médio Integrado
Authors: Soares Viviane Dos Ramos , Moura Jonathan Ribeiro Farias de
Published: August 2022

Este trabalho pretende pensar a questão da historicidade no ensino de Língua Portuguesa praticado no Ensino Médio Integrado. A partir de uma proposta de interferência nos modos de constituição histórica do sujeito e do sentido, nos interessa problematizar o sentido de “através de” como “meio, travessia entre o texto e o sujeito”, cuja significação “é mensagem, é conteúdo” (SILVA, 2017). Ler, escrever e interpretar são compreendidos a partir dos referenciais da Análise Materialista do Discurso nos termos de Michel Pêcheux e Eni Orlandi. Na ausência de uma problematização acerca do ideal de linearidade, de literalidade e de completude, temos o apagamento ou o silenciamento não apenas das línguas indígenas, africanas, de imigração e de fronteira que funciona(va)m no espaço de enunciação brasileiro como também das línguas de nossos sujeitos-alunos. A pergunta então é: como significar uma língua com historicidade no trabalho em sala de aula, em especial, na Educação Básica? Uma possibilidade de trabalho é apresentada e discutida em dois textos que circulam no discurso digital, cujo tópico gramatical privilegiado é o uso dos pronomes. Demonstramos que, quando o nível discursivo representado pela textualidade não é trabalhado, esvai-se a possibilidade de operar a gramática como forma de ver como o sujeito está significando sua posição. Num percurso em que consideramos tanto a gramaticalidade como a textualidade e a discursividade, trabalhamos os vestígios da textualização, a fim de compreender a complexidade e as contradições de uma sociedade marcada fortemente pela divisão social. Mostrando, na prática, o ensino de língua com historicidade.

В АО «Мосводоканал» проведены испытания пилотной установки микрофильтрации на базе дискового фильтра с тканевым фильтрополотном. Установка, предоставленная АО «НПК Медиана-Фильтр», предназначена для доочистки биологически очищенной воды от взвешенных веществ. Дисковая микрофильтрация с тканевым фильтрополотном (объемный тип фильтрации) позволяет доочистить биологически очищенную сточную воду от взвешенных веществ до 4 мг/л при использовании тканевого фильтрополотна типоразмера «10 мкм» и до 2 мг/л – типоразмера «5 мкм». При скорости фильтрации 8,5 м/ч расход промывной воды составил 0,7–1,4% от расхода воды на установку для ткани типоразмера «10 мкм» и 5,8–6,8% для типоразмера «5 мкм». При удалении взвешенных веществ в составе взвеси также происходит удаление ХПК, БПК5, общего азота и общего фосфора. Установки микрофильтрации с объемным типом являются аналогами установок с плоскостным типом и могут использоваться для достижения высокого качества доочистки биологически очищенной воды от взвешенных веществ.

Mosvodokanal JSC carried out tests of a pilot microfiltration plant based on a disk filter with a fabric filter cloth. The pilot plant supplied by Mediana-Filter RPC JSC has been designed for removing suspended solids from effluent in the process of tertiary treatment. Disk microfiltration with fabric filter cloth (volumetric filtration type) provides for removing suspended solids to 4 mg/l in the effluent after biological treatment while using fabric filter cloth of 10 µm typical size and to 2 mg/l while using 5 µm filter cloth. At 8.5 m/h filtration rate the consumption of wash water for the pilot plant for 10 µm filter cloth was 0.7–1.4% of the water flow, and 5.8–6.8% for 5 µm filter cloth. Beside suspended solids present in the suspension, COD, BOD5, total nitrogen and total phosphorus are also removed. Microfiltration plants of volumetric type are similar to the plants of flat type and can be used to ensure high quality tertiary treatment of effluent after biological treatment to remove suspended solids.

Authors: Benasayag Ariel , Piracón Fajardo Jaime Andrés
Published: August 2022

El artículo espera contribuir al pensamiento sobre las relaciones entre escuela y medios audiovisuales en Argentina. Propone un análisis de las articulaciones y tensiones presentes en los vínculos entre cine y discurso pedagógico a lo largo del siglo XX, en diálogo con la historización de las relaciones entre videojuegos y escuela. Esta lectura comparativa permite identificar continuidades, rupturas y resignificaciones en los modos como la pedagogía concibió la novedad tecnológica y cultural de sendos medios. Al mostrar que los videojuegos están atravesando un momento semejante al que experimentó el cine hace algunas décadas, ofrece claves para reflexionar sobre las prácticas escolares contemporáneas y las políticas educativas (o la ausencia de ellas) respecto de las imágenes.

Consideraciones acerca del manejo del repertorio de películas: los profesores y la clase
Authors: Do Amaral Peruffo Gabriela
Published: August 2022

Este artículo se elaboró con el objetivo de analizar la forma en que los profesores de historia se encargan de su repertorio cuando eligen películas para sus clases. Para esto, se analizaron las conexiones entre cine y educación, profundizando los temas relacionados con el currículo de historia dentro de los referenciales nacionales de educación básica. El concepto de repertorio se desarrolló desde la idea de colección de Thierry de Duve, en aproximación con la noción de canon, entendida como un rasgo privilegiado dentro del repertorio. Así fue posible acercar el concepto de repertorio al enfoque de Bourdieu sobre la distinción, el capital cultural y el arbitrario cultural. El material fue analizado con el fin de dialogar con la noción de encargarse del repertorio, y desde ella se generaron puntos de análisis relacionados con tres momentos de la elaboración de las clases.

Introduction: The current rise in polyresistant bacterial strains is due to self-medication, failure to comply the treatment, incorrect prescription of antibiotics by the physician, and even the abuse of these in agriculture industries. In this research, we suggest another possible source. Humans, being in coexistence with dogs and in contact with their saliva, could have been exposed to polyresistant microorganisms that are potential pathogens to. Identify, isolate and analyze these possible microorganisms were the main objectives of this study. Materials and methods: Oral samples (n=28) from domestic dogs were taken and cultured. Bacterial colonies (n = 160) were obtained and subjected to identification and antimicrobial sensitivity tests. Results: From 160 isolated colonies, the most prevalent species was Staphylococcus haemolyticus. Other bacteria such as Enterococcus faecium, Escherichia coli, Proteus mirabilis, and Pseudomonas aeruginosa were also found in a lesser proportion. There was an increased resistance of the bacteria against cell wall synthesis antibiotics. The resistance towards vancomycin was the highest, followed by cefalotin and cefixime. In contrast, all bacteria were sensible to imipenem. Conclusion: The resistance observed against protein synthesis inhibitors showed a high resistance towards erythromycin and clarithromycin but a high sensibility to amikacin and gentamicin. In this study several human pathogens that are the cause of infectious diseases were identified in the oral microbiota of dogs. Furthermore, another risk of polyresistant bacteria transmission is proposed with the determination of each bacterial resistance.
Dysphagia as a predictor of malnutrition risk in older adults: a brief review of literature
Authors: Kababie-Ameo Rebeca , Gutiérrez-Salmeán Gabriela
Published: August 2022

Dysphagia is known as any alteration of the swallowing process that affects the ability to eat a The use of mild and aromatic nd/or drink and presents in 30−40% of hospitalized patients. In the elderly, it is highly relevant due to its association with the development of frailty, malnutrition, and the high risk of morbidity and mortality. A set of factors has been proposed as a cause of dysphagia, such as anatomical and physiological alterations, neurological pathologies, drugs, and sarcopenia. Thickening liquids and texture-modified foods may be beneficial for patients with dysphagia, but they can also promote malnutrition if not prescribed properly. That is why nutritional support is key to avoid the risk of aspiration and malnutrition, which in turn, contribute to the development of dysphagia.

Abstract: Ahiputana (napkin rash) is one of the commonest diseases of balaawstha (mainly infantile age) which is discussed by various Ayurvedic Acharyas in their respective literature. Acharya Sushruta described Ahiputana in Ksudra roga. According to Acharya Vagbhatta, either due to malaoplepa (coating of faeces) or sweda (by excess of sweat), rashes develops in perianal region due to rakta and kapha doshas, which is tamravrana (copper coloured), with itching and later on associated with many complication. Diaper rash is a disease which occurs in infantile group having similar causative factors, sign/symptoms, pathogenesis as described in Ahiputna. It is more common in artificially fed infants and those with poor perineal hygiene. It is usually caused by skin irritation from prolonged contact with urine and faeces. It is usually seen around the groin and inside the folds of the upper thighs and buttocks. Various Ayurvedic medicines have been described in treatment of Ahiputana

How are we able to fix it so as to theoretically go over it, if the optimality and efficiency of the orbital angular momentum (OAM) multiplexing technique in a multi-input multi-output (MIMO) system fails in practice $-$ something that technically causes a considerable reduction in the maximum achievable value of the transceiver's degree-of-freedom? Is the aforementioned challenging issue theoretically interpretable?
Azimuthal Fourier Decomposition for Loss Analysis of Hollow-Core Tube Lattice Fibers Part I: Ideal Fibers
Authors: Melli Federico , Vasko Kostiantyn , Rosa Lorenzo , Benabid Fetah , Vincetti Luca
Published: August 2022

This is the pre-review draft of the first of two papers submitted to Journal of Lightwave Technology, where we propose and apply a methodology for the analysis of the loss in tube lattice fibers (TLFs) based on the azimuthal Fourier decomposition (AFD) of the fiber’s modes along the perimeters of the tubes composing the fiber cladding. This technique combined with the coupled mode theory constitutes an effective approach for gaining insight in the waveguiding mechanism and for additional loss analysis due to fiber non-idealities. In this part I we describe the approach and apply it to loss analysis of ideal TLFs. The approach is then applied to the analysis of tube thickness variation effects in the part II.
Deep Learning-based Image 3D Object Detection for Autonomous Driving: Review
Authors: Alaba Simegnew
Published: August 2022

An accurate and robust perception system is key to understanding the driving environment of autonomous driving and robots. Autonomous driving needs 3D information about objects, including the object’s location and pose, to understand the driving environment clearly. A camera sensor is widely used in autonomous driving because of its richness in color, texture, and low price. The major problem with the camera is the lack of 3D information, which is necessary to understand the 3D driving environment. Additionally, the object’s scale change and cclusion make 3D object detection more challenging. Many deep learning-based methods, such as depth estimation, have been developed to solve the lack of 3D information. This survey presents the image 3D object detection 3D bounding box encoding techniques, feature extraction techniques, and evaluation metrics of 3D object detection. The image-based methods are categorized based on the technique used to estimate an image’s depth information, and insights are added to each method. Then, state-of-the-art (SOTA) monocular and stereo camera-based methods are summarized. We also compare the performance of the selected 3D object detection models and present challenges and future directions in 3D object detection.
Deep Neural Network Augmented Wireless Channel Estimation for Preamble-based OFDM PHY on Zynq System on Chip
Authors: Asrar ul haq Syed , Gizzini Abdul Karim , Shrey Shakti , darak sumit , Saurabh Sneh , Chafii Marwa
Published: August 2022

Reliable and fast channel estimation is crucial for next-generation wireless networks supporting a wide range of vehicular and low-latency services. Recently, deep learning (DL) based channel estimation has been explored as an efficient alternative to conventional least-square (LS) and linear minimum mean square error (LMMSE) approaches. Most of these DL approaches have not been realized on system-on-chip (SoC), and preliminary study shows that their complexity exceeds the complexity of the entire physical layer (PHY). The high latency of DL is another concern. This paper considers the design and implementation of deep neural network (DNN) augmented LS-based channel estimation (LSDNN) for { \color{black} preamble-based orthogonal frequency-division multiplexing (OFDM) physical layer (PHY)} on SoC. We demonstrate the gain in performance compared to the conventional LS and LMMSE approaches. Via software-hardware co-design, word-length optimization, and reconfigurable architectures, we demonstrate the superiority of the LSDNN over the LS and LMMSE for a wide range of signal-to-noise ratio (SNR), number of pilots, preamble types, and wireless channels. Further, we evaluate the performance, power, and area (PPA) of the LS and LSDNN application-specific integrated circuit (ASIC) implementations in 45 nm technology. We demonstrate that word-length optimization can substantially improve PPA for the proposed architecture in ASIC implementations.

Review of Deep Learning Methods for Individual Treatment Effect Estimation with Automatic Hyperparameter Optimization
Authors: Sirazitdinov Andrei , Buchwald Marcus , Hesser Jürgen , Heuveline Vincent
Published: August 2022

Abstract—Estimation of individual treatment effect (ITE) for different types of treatment is a common challenge in therapy assessments, clinical trials and diagnosis. Deep learning methods, namely representation based, adversarial, and variational, have shown promising potential in ITE estimation. However, it was unclear whether the hyperparameters of the originally proposed methods were well optimized for different benchmark datasets. To solve these problems, we created a public code library containing representation-based, adversarial, and variational methods written in TensorFlow. In order to have a broader collection of ITE estimation methods, we have also included neural network based meta-learners. The code library is made accessible for reproducibility and facilitating future works in the field of causal inference. Our results demonstrate that performance of most methods can be improved using automatic hyperparameter optimization. Additionally, we review the methods and compare the performance of the optimized models from our library on publicly available datasets. The potential of hyperparameter optimization may encourage researchers to focus on this aspect when creating new methods for inferring individual treatment effect.
Part III - Spatially Dispersive Metasurfaces: Zero Thickness Modeling of Periodic and General Non-uniform Surfaces
Authors: dugan jordan , Nizer Rahmeier João , Smy Tom J. , Gupta Shulabh
Published: August 2022

A zero thickness model of non-uniform spatially dispersive (SD) metasurfaces is developed and demonstrated numerically for practical structures. This is an extension of [1], [2], which proposed a method of modeling uniform spatially dispersive metasurfaces by expressing their surface susceptibilities as rational polynomial functions in the spatial frequency domain. This led to the extended generalized sheet transition conditions (GSTCs) forming a set of differential equations relating the spatial derivatives of both difference and average fields around the surface that were then integrated into an integral equation (IE) solver. Here, the extended GSTCs are further developed to model non-uniform metasurfaces by approximating them as locally linear space invariant (LSI). Using this model, a semi-analytical Floquet method is derived to predict scattered fields from periodically varying metasurfaces. The extended GSTCs, Floquet method, and IE method are tested on several nonuniform surfaces consisting of short metal dipole cells of varying lengths exhibiting strong spatial dispersion. The physical surfaces are simulated in Ansys FEM-HFSS while their zero thickness equivalents, both dispersive and non-dispersive, are simulated using the Floquet and IE methods. Excellent agreement is shown between the Floquet-SD and IE-GSTC-SD methods and HFSS, demonstrating the importance of spatial dispersion to model their scattered fields.
Second-order filter-based inertia emulation (SOFIE)for low inertia power systems—Part 1: Principles and Equivalence with Synchronous Machines
Authors: Aragon Sotelo Diego
Published: August 2022

The massive integration of power electronic converters into the power grid has led to a decrease in the mechanical inertia of the power system, causing an increase in the rate of change of frequency (RoCoF) that may lead to stability problems. The scientific community has focused on developing grid-forming control techniques, although their implementation implies a significant change in the firmware of the converter. Grid-supporting approaches, on the other hand, are an interesting alternative to add frequency support to the grid while preserving the original control structure of the converter. This paper proposes three new grid-supporting control techniques based on the dynamic behaviour of a synchronous machine (SM) and its equivalence with a second-order low-pass filter. They endow the converter with the capability of providing synthetic inertia, damping, droop-based p/f primary response and virtual reactance. The dynamics of the proposed implementations are compared with those of a reduced-order synchronous machine by means of time-domain simulations and in-depth state-space based small signal analyses. Besides, their operation is validated in a nine-bus low-inertia power system. Hardware in the loop (HIL) laboratory results are used to validate experimentally the proposed techniques.
Three-stage Power Flow & Flexibility Reserve Co-Optimization for Converter Dominated Distribution Network Lookahead Model using Blockchain & S-ADMM — I: Method
Authors: Shah Chinmay , Wies Richard
Published: August 2022

The integration of power electronic converter (PEC)-based renewable distributed energy resources (DERs) and controllable loads in electric power grids is growing exponentially due to increased interest in reducing carbon emissions. However, the uncertainty in DER power output limits their contribution to the overall system reliability and alleviates its flexibility. Hence, three-stage power flow and flexibility reserve optimization are proposed to address these issues. In the first stage, the epistemic and aleatory uncertainties in the power flow problem are addressed by the proposed parameterized deterministic lookahead (DLA) method. The flexibility metric “variation in generation capacity (VIGC)” and sharing alternating direction method of multipliers (S-ADMM) based distributed optimization is used to schedule flexibility reserves and minimize its cost in the second and the third stage to enhance system flexibility. The flexibility reserve sharing and blockchain/smart contract-based bidding to schedule those reserves for multiple balancing authority (BA) areas are also proposed in this work. The proposed algorithm’s results and e?ectiveness are presented in Part II of this work.

Published: August 2022

In this paper, as a generalization the famous Gaussian sums, we introduce a new kind of mixed character sums and their applications in the constructions of Mutually unbiased bases (MUBs) and signal sets. It is well-known that MUBs have significant applications in quantum information processing and other fields. However, only a few constructions of MUBs are known in the literature. In this note, we provide a recursive constructions of approximately mutually unbiased bases. Meanwhile, we present some constructions of asymptotically optimal signal sets by using the mixed character sums.

Bencana memiliki dampak besar pada masyarakat, salah satu dampak yang muncul adalah trauma. Trauma ini paling rentan terjadi pada kelompok usia anak-anak. Penelitian ini bertujuan untuk mengetahui gambaran trauma psikologis pada anak usia sekolah (7-12 tahun) pasca gempa di Desa Mekkatta Kecamatan Malunda.  Desain penelitian deskriptif dengan teknik pengambilan sampel adalah total sampling dengan jumlah responden 50 orang. Memperoleh data dengan menggunakan Strengths and Difficulties Questionnaire (SDQ) yang terdiri dari 25 item pertanyaan. Penelitian ditemukan karakteristik responden yaitu sebagian besar berusia 7 tahun sebanyak 10 orang (20.0%), dan sebagian besar berjenis kelamin perempuan sebanyak 28 orang (56.0%). Gambaran trauma psikologis pada anak usia sekolah (7-12 tahun) menunjukkan pada subskala kesulitan sebagian besar dalam kategori perbatasan yaitu 27 orang (54.0%), normal 18 orang (36.0%), dan sebagian kecil kategori abnormal 5 orang (10.0%). Sedangkan subskala kekuatan sebagian besar dalam kategori normal yaitu 27 orang (54.0%), perbatasan 19 orang (38.0%), dan sebagian kecil kategori abnormal 4 orang (8.0%). Anak-anak yang berada pada kategori perbatasan artinya mereka membutuhkan stimulus yang mendukung proses adaptasi sehingga mengarah ke normal. Pada anak-anak yang berada pada kategori perbatasan dan abnormal perlu dilakukan intervensi kesehatan seperti terapi bermain.

Nausea and vomiting of pregnancy (NVP) adalah kecenderungan untuk memuntahkan sesuatu, atau sensasi yang muncul di kerongkongan atau epigastrium, dengan atau tanpa muntah. Hal ini dapat terjadi pada empat minggu pertama hingga pada minggu kedua belas kehamilan. Penatalaksanaan mual muntah selama kehamilan dapat dilakukan dengan terapi farmakologis dan non farmakologis, namun 34% wanita tidak mengkonsumsi obat dan 26% diantaranya mengurangi dosis karena kekhawatiran efek samping obat yang digunakan pada kehamilan. Jahe dapat digunakan sebagai salah satu terapi non farmakologis karena kandungan gingerol dan shogaol dapat meringankan mual dan muntah dengan meningkatkan tonus lambung dan motilitas karena adanya efek antikolinergik dan antiserotonergik. Penelitian ini merupakan penelitian deskriptif menggunakan metode Narrative Review dan dilaksanakan pada bulan Desember 2021 - Februari 2022. Pencarian artikel dilakukan secara hand searching pada dua database yaitu Google Scholar dan PubMed dengan menggunakan kata kunci “Jahe” OR “Zingiber officianale” AND Mual OR Nausea AND Pregnancy. 10 artikel memenuhi kriteria inklusi dan eksklusi. Artikel yang digunakan dalam penelitian ini 90% dari Indonesia dan 10% berasal dari Iran. Pemberian jahe pada ibu hamil telah diberikan dalam berbagai bentuk berupa minuman jahe hangat, kapsul ekstrak jahe 500 mg, dan aromaterapi. Pemberian intervensi dilakukan 1-3 kali sehari dan selama 4-30 hari. Rata-rata penurunan frekuensi mual dan muntah adalah 11 – 135%, dan penurunan tingkat keparahan dari tingkat sedang (moderate) menjadi tingkat ringan (mild). Jahe dapat mengurangi frekuensi mual dan muntah dan dapat mengurangi derajat keparahan mual dan muntah pada ibu hamil
