SE VOCÊ ESTÁ PROCURANDO A PRISÃO, VOCÊ ENCONTROU A TERRA
Authors: Marques Adalton
Published: October 2022

Neste artigo apresento um conjunto de formulações, enunciadas ou acionadas ao longo dos quarenta e cinco anos de existência da Comissão Pastoral da Terra de Juazeiro-BA, a respeito das relações entre o processo de expropriação de terras disparado pela construção da barragem de Sobradinho e a expansão das periferias de Juazeiro e Petrolina-PE. A formulação que tomo como guia desse conjunto e que utilizo como título deste artigo me foi formulada por Marina Rocha Braga, agente desse serviço pastoral. Foi ela quem chamou a minha atenção para essas relações dizendo que o estudo das periferias e prisões dessas cidades exige a compreensão do cativeiro da terra. Na primeira parte deste artigo eu trato desse encontro com Marina e de seus desdobramentos iniciais, enquanto na segunda parte procuro evidenciar como esse problema levantado por ela se adensa em outras formulações feitas por agentes pastorais e por companheiras/os de comunidades atingidas por grandes projetos energéticos, mas também como se conecta a formulações mais antigas que também compõem ou foram acionadas pelo mesmo trabalho pastoral. Na terceira e última parte eu apresento cinco exemplos que me foram expostos por Marina para explicar o que é o cativeiro, e em seguida, arriscando uma generalização, indico como eles fornecem elementos para pensar as periferias urbanas de Juazeiro e Petrolina como cativeiros por excelência, bem como para organizar os dados que venho reunindo sobre a expansão prisional e policial nessas duas cidades.
O POLICULTURALISMO E AS EVANGÉLICAS (JUDAIZANTES E NÃO JUDAIZANTES)
Authors: Mariz Cecília
Published: October 2022

A originalidade dos dados empíricos e do diálogo teórico com Saba Mahmood e seu conceito “agência religiosa feminina” e com Prashad e o conceito “policulturalismo” garantem o alto valor acadêmico do artigo de Carpenedo, em tela. Esse valor é maior porque é um texto que estimula questões. Nesses comentários listo algumas dessas questões, tais com, (1) por que considerar evangélicas mulheres que negam essa identidade, que adotam práticas e discursos não evangélicos se referindo aos evangélicos como o “outro”? (2) os sofrimentos relatados não revelariam antes falta de agência do que agência das mulheres? (3) de que forma o contexto policultural da sociedade brasileira mais ampla afeta mulheres que deixam clara a ruptura com essa sociedade? (4) não haveria um conceito “nativo” mais adaptado às mulheres brasileiras pesquisadas do que “devoto” (pious) escolhido por Mahmood por ser nativo entre islâmicos.

Dynamic Channel Pruning with Adaptive Weight Learning
Authors: Wu Shuanglin , Xiao Chao , Yang Jungang , An Wei
Published: October 2022

Dynamic channel pruning is widely used in model compression to improve
the efficiency of neural networks. Although dynamic pruning can remove
redundant channels dynamically, the parameters still remain unchanged,
which can limit the performance as the response of each neuron changes
with different inputs. In this paper, we propose a novel dynamic channel
pruning method with adaptive weight learning, which can adaptively
adjust both the parameters and widths of the filters simultaneously.
Specifically, we design an adaptive-weight convolution module, which can
be customized for different inputs under the guidance of global context
information to capture representative local patterns and synthesize
interested features. At the same time, we utilize a channel importance
prediction module to predict the saliency of each channel. Based on the
channel saliency, unimportant channels can be removed dynamically to
speed up the convolution. These two modules work jointly to achieve a
good trade-off between model performance and computational complexity.
Experiments on image classification and object detection tasks
demonstrate that our method can greatly reduce the computational burden
while maintaining the performance, which outperforms state-of-the-art
methods.

Authors: zhang kun , Zang Lan , Zhang Shengrong , Zhu Yupeng , Wang Haifeng , Huang Ju
Published: October 2022

According to the receiving array size, the underwater acoustic
positioning system can be divided into three positioning systems: long
baseline (LBL), short baseline (SBL) and ultra-short baseline (USBL).
Acoustic detection and positioning technology based on ultra-short
baseline is the most effective means to collect and transmit
information, and is an effective way to solve the positioning accuracy
of underwater vehicles. In this paper, the short baseline positioning
and navigation system is studied deeply, and an underwater acoustic
positioning algorithm based on extended Kalman filter is proposed. By
fusing the information of pressure gauge, digital compass and
accelerometer of the robot, the positioning accuracy is improved and the
influence of underwater channel multipath effect on the system is
reduced.

BACKGROUND Severe acute respiratory syndrome corona virus
(SARS-CoV-2) infection frequently causes severe and prolonged disease
but only few specific treatments are available. We aimed to investigate
safety and efficacy of a SARS-CoV-2-specific siRNA-peptide dendrimer
formulation (MIR 19 ®) targeting a conserved sequence in known
SARS-CoV-2 variants for treatment of COVID-19. METHODS We
conducted an open-label, randomized controlled multicenter phase II
trial (NCT05184127) evaluating safety and efficacy of inhaled MIR 19 ®
(3.7mg and 11.1 mg/day: groups 1 and 2, respectively) in comparison with
standard etiotropic drug treatment (group 3) in patients hospitalized
with moderate COVID-19. The primary endpoint was the time to clinical
improvement according to predefined criteria within 14 days of
randomization. RESULTS Patients from group1 had a significantly
reduced (median 6 days (95% confidence interval [CI]: 5-7, HR 1.75,
P=0.0005) time to clinical improvement compared to patients from group 3
(8 days (95% CI: 7-10). Normalized oxygen saturation (SpO
>94%) occurred quicker in the group 1
(median 5 days (95% CI: 4–5, HR 1.59, P=0.0033) than in the group 3 (6
days, 95% CI: 5–8). Treatment with MIR 19® was well tolerated and
safe. CONCLUSIONS MIR 19 ®, a SARS-CoV-2-specific siRNA-peptide
dendrimer formulation is safe and significantly reduces time to clinical
improvement in hospitalized moderate COVID-19 patients compared to
standard therapy in a randomized controlled trial. MIR 19 ® treatment
targets a sequence which is identical in all SARS-CoV-2 variants known
so far and hence should be applicable for all of them.

Microbioreactors for nutrient-controlled microbial cultures: Bridging the gap between early bioprocess development and industrial scale use
Authors: Totlani Kartik , Tatenhove-Pel Rinke van , Kreutzer Michiel , Gulik Walter M. van , Steijn Volkert van
Published: October 2022

It is common practice in the development of bioprocesses to genetically
modify a microorganism and study a large number of resulting mutants in
order to select the ones that perform best for use at the industrial
scale. At industrial scale, strict nutrient-controlled growth conditions
are imposed to control the metabolic activity and growth rate of the
microorganism, thereby enhancing the expression of the product of
interest. Although it is known that microorganisms that perform best
under these strictly controlled conditions are not the same as the ones
that perform best under uncontrolled batch conditions, screening, and
selection is predominantly performed under batch conditions. Tools that
afford high throughput on the one hand and dynamic control over
cultivation conditions on the other hand are not yet available.
Microbioreactors offer the potential to address this problem, resolving
the gap between bioprocess development and industrial scale use. In this
review, we highlight the current state-of-the-art of microbioreactors
that offer the potential to screen microorganisms under dynamically
controlled conditions. We classify them into: (i) microtiter plate-based
platforms, (ii) microfluidic chamber-based platforms, and (iii)
microfluidic droplet-based platforms. We conclude this review by
discussing the opportunities of nutrient-fed microbioreactors in the
field of biotechnology.
Adenoid Cystic Carcinoma of the Bartholin’s Gland: A Review
Authors: Fu Zhaojie , Zheng Chengyu , Wang yuhan , Zhou Haijian , Peng Yu , Yao Tingting
Published: October 2022

Adenoid cystic carcinoma of Bartholin’s gland (BG-ACC) is a rare vulvar
carcinoma which has its own unique characteristics, such as growing
slow, local invasion, perineural infiltration and high local recurrence
rates. Signs and symptoms are nonspecific. Perineural invasion may be
the reason for causing pain and high recurrence rates. There is no
consensus on treatments. We collect all current literatures about BG-ACC
to summarize the clinical features, histological features and treatment
options. Surgery is the cornerstone of treatments. Adjuvant chemotherapy
and radiation therapy may be beneficial in case of distant metastasis.
We also need more research in molecular targeting therapy.

Authors: Rabah Djekidel , Lahdeb Mohamed , Ghoneim Sherif , Mahi Djillali
Published: October 2022

The main purpose of this paper is to model and analyze the electrostatic and electromagnetic interferences between a HV overhead power line and an aerial metallic pipeline situated parallel at a close distance. The modelling of these interferences is typically done for safety reasons, to ensure that the induced voltage does not pose any risk to the operating and maintenance personnel and to the integrity of the pipeline. The adopted methodologies respectively for electrostatic and electromagnetic interferences are based on the charge and current simulation methods combined with the Teaching learning based optimization (TLBO) algorithm. The Friedman test analysis indicate that teaching learning based optimization (TLBO) algorithm can be used for parameters optimization, it showed better results. In the case where the induced currents and voltages values exceed the limit authorized values by the international CIGRE standard, mitigation measures become necessary. The simulation results obtained were compared with those provided respectively by the admittance matrix analysis and Carson's method, good agreement was obtained.

Drones micro-Doppler signatures obtained by FMCW radars are an excellent
procedure for malicious drone detection, identification and classification.
There are a number of contributions dealing with recorded spectrograms with
these micro-Doppler signatures, but very low number of them has analyzed
possibility to calculate echo caused by drone moving parts. In this paper,
starting from already existing mathematical apparatus, we presented such
spectrograms as a function of changing drone moving parts characteristics:
rotor number, blades number, blade length and rotor moving speed. This
development is the part of a wider project intended to prevent malicious
drone usage.

Authors: Radivojevic Jovan , Mileusnic Mladen , Lebl Aleksandar , Marinkovic-Nedelicki Verica
Published: October 2022

The main objective of this paper is the analysis of comb jamming as a technique for RCIED activation prevention. Presentation of three strategies for comb signal generation follows after comprehensive survey of various jamming techniques in the introduction. There are two paper original contributions. The first one is quantitative comparison for three signal generation techniques of their emission power in relation to barrage jamming under the condition of equal BER value. The second contribution is determination of exact BER value as a function of emission power in the case of barrage jamming. Until now we have made different analyses and comparisons starting from estimated emission power. The analysis procedure is performed for QPSK modulated RCIED activation signal. Power saving is evident for all three methods of jamming signal generation. It is proved that additional 2.5dB of power saving is achieved by equalization of frequency components level in comb signal. The analysis in this paper shows that comb jamming allows the same effects as barrage jamming, but with lower emission power.
Control of series impedance of power lines using power flow controller
Authors: Markovic Aleksandar , Vukosavic Slobodan
Published: October 2022

In this paper, the possibility of unified power flow controller (UPFC) to modulate both series resistance R and series reactance X of an overhead power line is discussed. The classical power flow control system of the UFPC is modified in the manner that standard input references signals (active and reactive powers) are replaced by reference signals of series resistance and reactance. Using the procedure described in this work, the reference signals for active and reactive powers are generated indirectly. The operation of UPFC in proposed operation mode is analyzed using computer simulation, based on a model of single machine infinite bus (SMIB) with constant impedance loads and two parallel lines. The goal is to show that UPFC is capable to control both series line parameters (R and X) directly and independently by means of a simple control system without additional decoupling controllers. An additional task is to show that power flows can be indirectly controlled this way. The step response of series line resistance and reactance is used to validate the operation of the proposed control system. The obtained results clearly show that all goals are fulfilled.
Improving performance of transmission networks using facts through continuation power flow method
Authors: Alnasseir Jamal
Published: October 2022

Over the past 50 years, modern electrical systems have become more complex, as they overrun the geographical boundaries of neighboring countries. The problem is that the power system faces many challenges, because it is exposed to difficult operating conditions. The phenomenon of voltage instability is the most frequent phenomenon, and this can lead to the collapse of the power system. To avoid power outages in the system (especially in blackout situations), the power system must be analyzed in order to maintain voltage stability in the expected difficult operating conditions. The main objective is to determine the maximum load capacity of the system and the causes of voltage instability. The voltage instability problem is related to the nature of nonlinear loads, so different load characteristics must be taken into consideration when analyzing voltage stability. This study aims to discover the maximum load capacity required by using the continuous power flow method (CPF) in the studied network. Then, the performance of this network using a Flexible Alternating Current Transmission System (FACTS) will be utilized. FACTS systems present a promising solution in improving the voltage stability by improving the power transmission capacity and controllability of the parameters of the existing power networks. This study will be conducted on a reference network platform under normal working conditions, then installation of one of the FACTS systems will show its effect on improving voltage stability. The continuous power flow method will be used to find PV curves, which in turn will help to determine the conditions of maximum loading while maintaining stability, and identify the bus bar with the smallest voltage, on which the flexible AC systems will be installed. The software environment MATLAB/PSAT will be used for modeling and simulation.

Herramientas learning como medio de apoyo en la disminución de la reprobación en la Universidad Autónoma del Carmen para la modalidad a distancia
Authors: Barradas Arenas Ulises Daniel , Cocón Juárez José Felipe
Published: October 2022

De acuerdo con datos estadísticos, en la Facultad de Ciencias de la Información 40 % de los estudiantes abandona por casos de deserción y 30 % por rezago escolar, lo cual ocurre durante el primer año escolar debido a reprobación de materias. El modelo Acalán de educación a distancia basado en el constructivismo plantea estrategias de apoyo contra la reprobación, pero estas no son suficientes. Por eso, esta investigación tiene como objetivo evaluar el impacto de un repositorio de herramientas de aprendizaje e-learning y las estrategias didácticas aplicadas para disminuir la reprobación en la licenciatura en Tecnologías de la Información de la Universidad Autónoma del Carmen. En concreto, se utilizaron tres instrumentos con los cuales se validó la viabilidad de la propuesta, que incluyó los objetos de aprendizaje necesarios para integrarlos en el repositorio, para lo cual se midieron las necesidades de estudiantes y profesores. La metodología usada se apoyó en una muestra de 17 alumnos regulares, 10 irregulares y tres profesores que trabajaron en un curso de programación con apoyo del repositorio. Como resultado se obtuvo que de los alumnos inscritos en el curso solo 29 % reprobara la asignatura. Asimismo, la aplicación del modelo de regresión lineal y Anova mostró que las variables falta de interés y mayor calidad en los contenidos son factores que impactan en la reprobación.  En síntesis, se recomienda un entrecruzamiento con la carrera de Ingeniería en Diseño Multimedia para la elaboración de materiales de alta calidad que permitan evaluar las herramientas de trabajo e-learning idóneas para un mejor desempeño por parte de los docentes en las unidades didácticas.

The article examines the results of the development of an algorithm for determining the number of pixels of a fractal image of the "Fractal dust" type (Cantor's set) created using resolution-limited RSIF. Mathematical formulas and schemes for calculating the number of pixels of the fractal image and the number of iterations of the RSIF fractal have been derived. This algorithm consists in finding formulas depending on the number of figures of the first iteration, similarity coefficients, and resolution. This makes it possible to determine the number of pixels for an existing fractal image with different resolutions. The calculation algorithm does not use the entry of a loop into a loop and recursive functions, and is quite optimized, which allows without spending a lot of computing power. The use of formulas in the future will make it possible to determine the number of random events (stochastic movement of a point), to ensure the quality of the reproduced image using RSIF, will make it possible to form an initial data set for neural networks, which will form the basis of object recognition.

An accurate analytical solution for positioning technologies based on both the difference of distances from the object to reference points (TDOA) and the distances themselves (TOA) is considered. The bijection of the obtained coordinate transformation allows reducing the problem of hyperbolic positioning to the Cartesian coordinate system. It is shown that all localization systems of the same rank with different numbers of sensors reduce to a single canonical form with a fixed number of (virtual) sensors corresponding to the dimension of space plus one. The resulting solution allows us the simultaneous observation of many objects, both close and distant, with determination of the distance to them. The possibilities of using positioning systems with a reduced rank have been analyzed. The synthesis of a sensor system with a higher rank from several separate systems is considered. Algorithms for solving the problem are linear and allow direct reconstruction of the image of objects

The paper is devoted to study of the charge carrier transfer characteristics in the silicon microcrystals doped by boron to concentrations corresponding to the metal-dielectric transition, as well as modified by a transition metal admixture with an unfilled 3d+ shell of the local magnetic moment. The magnetoresistance of microcrystals under the magnetic field action to 14 T at the cryogenic temperatures was studied. A detailed analysis of the results of studies of magneto-transport properties of crystals was carried out. It was found that the low-temperature transport of charge carriers for silicon microcrystals is based on hopping polarization conduction.

Chemotherapy-induced cardiotoxicity is a major cause of morbidity and mortality in cancer survivors. Myocardial dysfunction is one of the most frequent problems of chemotherapy, with highly important unfavorable effects on the prognosis in the short and long term. Its association with malignant pathology influences the compliance with specific oncological therapy and the healing process as well. Therefore, the myocardial dysfunction is becoming a reason for expanded morbidity and even early mortality for this category of patients. Our study demonstrates that cytostatics in the anthracycline class, especially Doxorubicin with a cumulative dose of more than 400 mg/m2, their association with "targeted" molecular therapies and Cyclophosphamide, along with the co-existence of cardiovascular risk factors such as hypertension and dyslipidemia, can affect longitudinal myocardial mechanics, which can be studied and tracked by decreasing the LSsubendo echocardiographic parameter in the first 12 months of cytostatic treatment. After the 6th dose of chemotherapy, approximately 50% of the patients under study had pathological changes in LSsubendo, and after the 8th treatment this number rose to 88%. In our study we demonstrated that the reduction in GLS between the two evaluated moments, pre-treatment and after 12 months, was influenced by the treatment with anthracyclines, with Doxorubicin administered in a cumulative dose > 400 mg/m2, with the association of cytostatic classes consisting of: anthracyclines, "targeted" molecular therapies, and cyclophosphamide, and by the coexistence of hypertension and dyslipidemia. Our results on the variation of GLS and LSsubendo at 12 months of the research for patients with hematological neoplasia are consistent with other data in literature, with myocardial deformity parameters changing early during cytostatic specific treatment, thus preceding a decline in LVEF. An early diagnosis of myocardial dysfunction is feasible by using longitudinal deformation criterion (parameters) assessed by 2D speckle tracking echocardiography.

Batuk  merupakan refleks pertahanan tubuh alami yang membersihkan saluran pernapasan dari benda asing. Dekstrometorfan merupakan obat antitusif yang bersifat antagonis non-competitive chanel blocker terhadap reseptor N-Methyl-D-aspartate yang mampu menekan batuk di pusat ambang batuk. Penelitian ini bertujuan untuk menganalisis potensi naringenin sebagai antitusif berdasarkan nilai afinitas pengikatannya dengan reseptor NMDA, sifat farmakokinetik, potensi biooral dan toksisitas melalui pendekatan in silico dengan teknik molecular docking. Hasil penelitian menunjukkan, bahwa dekstrometorfan dan naringenin berikatan di residu asam amino yang sama dengan NMDA pada MET A: 145, ILE A: 85, ALA B: 888 dengan ikatan hidrofobik, SER A: 81 dengan ikatan hidrogen pada dekstrometorfan dan ikatan unfavorabel donor-donor pada naringenin. Nilai binding affinitas naringenin -6,7 kkal/mol lebih kecil dibandingkan dengan dekstrometorfan -6,4 kkal/mol, hal ini menunjukkan bahwa naringenin berpotensi sebagai antitusif yang hampir sama dengan dekstrometorfan. Hasil uji toksisitas, menunjukan bahwa naringenin dan dekstrometorfan dapat dikonsumsi secara oral dan tidak berbahaya bagi kesehatan. Analisis potensi bioral dan uji farmakokinetik membuktikan bahwa naringenin mampu diabsorbsi, didistribusi, dimetabolisme dan diekskresi, sehingga berpotensi sebagai kandidat obat antitusif.

Perubahan iklim merupakan krisis global yang berdampak buruk tidak hanya pada lingkungan alam tetapi juga berpengaruh terhadap kondisi sosial, ekonomi, dan politik dalam masyarakat. Ketika terjadi pengrusakan alam, kaum miskinlah yang menjadi korban, sementara alam terus-menerus dimanfaatkan oleh pemilik modal multinasional secara berlebihan. Grup musik asal Indonesia KePAL-SPI dan Burgerkill menggarap topik lingkungan hidup dan ketidakadilan sosial dalam sejumlah lirik lagu yang dibahas dalam artikel ini, yakni “Balada Peladang”, “Jaga Kampung”, “Tanah Leluhur”, “Hancur”, dan “Undamaged”. Melalui metode close reading, dilakukan analisis atas kelima lirik lagu tersebut dengan terang Teori Ekokritik. Hasil pembacaan menunjukkan bahwa lirik lagu-lagu terpilih memiliki dua tema pokok. Pertama, seruan untuk merawat alam dan menjaga tradisi leluhur yang ramah lingkungan menjadi pesan utama. Kedua, kemerosotan alam dan degradasi martabat manusia terjadi bersamaan. KePAL-SPI dan Burgerkill menyampaikan protes atas eksploitasi alam yang abai akan kepentingan bersama. Alih-alih menjaga keutuhan semua ciptaan, kehadiran kapitalisme global menyisakan ketidakadilan bagi kelompok miskin, rentan, dan terpinggirkan.

Karna, salah satu tokoh dalam novel Mahabharata karya Nyoman S. Pendit—novel adaptasi dari Epos Mahabharata. Mengingat bahwa Karna merupakan salah satu tokoh dalam karya sastra, penulis ingin mengetahui kepahlawanan tokoh Karna dengan kerangka berpikir Semiotika Teeuw. Penelitian ini bertujuan untuk memaknai kode-kode bahasa, sastra, dan budaya pada tokoh Karna dalam novel dengan maksud menemukan makna terdalam dari tokoh Karna. Dalam penelitian ini ditemukan bahwa perjalanan hidup dan kepahlawanan Karna adalah ajaran hidup manusia yang melaksanakan dharmanya di dunia.Dari ketiga hasil analisis kode-kode tersebut, ditemukan bahwa kepahlawanan Karna tidak hanya terletak dari kesetiaannya pada Kaurawa, melainkan pula perjalanan hidupnya dari lahir, kebenciannya terhadap Pandawa, kutukan yang ia dapatkan, hingga pada akhirnya bersatu dengan Pandawa di Surgaloka bahwa hidupnya merupakan pahlawan bagi yang melaksanakan dharma. Perjalanan hidup Karna yang melaksanakan dharma dapat menjadi bahan pembelajaran bagi manusia untuk hidup pada jalan dharma.
