La escritura como reescritura en la narrativa sobre hechos reales. De “La chica muerta” a Chicas muertas
Authors: García Victoria
Published: July 2023

Chicas muertas, de Selva Almada (2014), se inserta en un proceso de (re)escrituras que se inicia con “La chica muerta” (2007) y se ramifica en distintos textos posteriores de la autora. Nuestro trabajo aborda dicho proceso. Partimos de un análisis de “La chica muerta”, que subraya los rasgos que lo configuran como un texto relativamente autónomo, capaz de desprenderse de su contexto de origen. A continuación, consideramos, como reescrituras de aquel relato, Chicas muertas (2014) y “La muerta en su cama” (2015). Aunque ambos textos surgen de un intento autorial por eludir las inexactitudes en la reconstrucción narrativa del crimen de Andrea Danne, en rigor el núcleo básico de los hechos permanecerá desconocido. Será la construcción de una serie de crímenes y su reinterpretación como femicidio lo que proveerá una posible clave de sentidos para narrar los acontecimientos.
Entrega tu Vida a la Economía: Gestión de la Muerte y Neoliberalismo en el Brasil de la Pandemia
Authors: Ferrugem Daniela , Cristiano Gabriela Dutra
Published: July 2023

Este ensayo es una reflexión sobre las formas en que la pandemia de Covid-19 ha re-editado y actualizado los viejos dispositivos del neoliberalismo y la gestión de la muerte en la escena brasileña. Partimos de la discusión sobre algunos imperativos y mensajes reiterados desde marzo de 2020 en los medios de comunicación que transmiten una falsa idea de libertad de elección en relación con la protección individual, mientras el Estado, reforzando la ideología neoliberal y produciendo sentimientos de fracaso, culpa, miedo, desprotege materialmente a gran parte de la población. Luego, articulamos nociones sobre neoliberalismo y desprotección social para pensar cómo se ha llevado a cabo la gestión de la muerte en el escenario de la pandemia. Finalmente, reflexionamos sobre las posibilidades o no de la insurgencia, fomentando la idea de que las redes de solidaridad que se han construido son, en realidad, solidaridad e identidad de clase a partir de lo que nos asemeja como humanos.

La Estética Andina del Textil y el Procedimiento del Zurcir en Cuando Sara Chura despierte
Authors: Galeas Daniel Sebastián
Published: July 2023

Desde una perspectiva crítica contra la autonomía del arte, el presente trabajo esboza las principales categorías estéticas del pensamiento andino prehispánico a partir de algunos aportes de los estudios antropológicos y del contraste con la estética occidental de la recepción, presentada por Hans Jauss en su Pequeña apología de la experiencia (1972). Para este procedimiento doble, se aborda la figura de la producción textil que, al resultar central para la sensibilidad de los pueblos andinos, condensa la totalidad de su pensamiento estético. A partir de esto, se analizan los rasgos de la estética andina en la novela Cuando Sara Chura despierte (2003) del boliviano Juan Pablo Piñeiro y se propone que la construcción narrativa establece un símil con la elaboración de un textil. Así, se destacan las maneras en que la estética andina prehispánica y la figura del textil aparecen en la obra y catalizan posibilidades sensibles para su recepción, al operar en ellas una crítica social decolonial; la cual resulta importante rescatar.

Exploiting the Potential of Satellite Microwave Remote Sensing to Hindcast the Storm Surge in the Gulf of Venice
Authors: De Biasio Francesco , della Valle Antonio , vignudelli stefano , Bajo Marco , umgiesser georg , zecchetto stefano
Published: July 2023

The potential of active microwave satellite observations of sea surface height (radar altimetry) and of sea surface wind (radar scatterometry) has been exploited for storm surge modeling purposes. The altimetry observations were assimilated into a storm surge model (SSM) with a dual 4D-Var system, in order to obtain the best possible surge level field as initial condition to reforecast runs. The scatterometer wind data were instead used to improve the accuracy of the wind fields of a global atmospheric model used as forcing to the SSM through a procedure that has been proved to be able to reduce the differences between the model winds and the scatterometer observations. Hindcast experiments were performed to test the sensitivity of the SSM to the altimetry data assimilation and to the modified wind forcing.Remarkable improvements of the storm surge level hindcast have been obtained for what concerns the modified model wind forcing, while encouraging results have been obtained with the altimeter data assimilation.
On Shape, Orientation, and Structure of Atmospheric Cells Inside Wind Rolls in Two SAR Images
Authors: zecchetto stefano , De Biasio Francesco
Published: July 2023

Synthetic aperture radar (SAR) images of the sea surface often show roll-vortex structures and other features which, in general, are spread out over several length scales and may present spatial periodicity as well as intermittence.  Standard techniques, such as two-dimensional (2-D)  Fourier analysis, are unsuitable both when it is of interest to detect intermittent phenomena and to analyze the spatial disposition of the backscatter structures inside the SAR images. For the above reasons, the 2-D continuous wavelet transform analysis has been applied to two European Remote Sensing mission SAR images over the Mediterranean Sea, showing wind rolls and atmospheric gravity waves. Through the evaluation of the wavelet variance map, which ideally corresponds to the 2-D Fourier spectrum, it has been possible to assess the presence of two main energy areas at large (from 7–28 km) and small (from 0.5–2 km) spatial scales. While the large-scale fluctuations may be ascribed to atmospheric gravity waves and other features induced by the surroundings, the small-scale fluctuations reveal the inner structure of the atmospheric wind rolls. The SAR-like maps, obtained by adding the wavelet coefficient maps pertaining to the small scales, have permitted to highlight the high- and low-intensity backscatter cells associated with the wind rolls. These cells have been statistically characterized by means of the frequency distributions of the size of the cells maximum and minimum axes, of the orientation of the maximum axis, and of their area. The results indicate that high- and low-intensity backscatter cells have similar characteristics in both cases studied: they appear of elliptic shape, with the major axis along the wind roll direction; the average axes ratio is 2.5:1. The frequency distributions of the cells area indicate a continuous distribution of sizes, without significant gaps.
A Wavelet-Based Technique for Sea Wind Extraction from SAR Images
Authors: zecchetto stefano , De Biasio Francesco
Published: July 2023

We present the follow-up of our previously published work, where we described a wavelet-based method to characterize the sea surface backscatter structures in Synthetic Aperture Radar (SAR) images. The method relies on the ability of the 2-D continuous wavelet technique to detect the spatial structure of the Marine Atmospheric Boundary Layer (MABL) and to isolate wind-related cells and features. The analysis of the cells’ geometry, molded by the radiometric characteristics of the sea surface, permits the identification of the wind direction inside the cells, due to the along-wind asymmetry of backscatter structures, and thus the computation of the wind speed through standard algorithms. Twenty-one SAR images (ERS-2 and Envisat ASAR Wide Swath) over the Mediterranean Sea have been analyzed, and the results are compared with satellite wind fields. The images cover a range of meteorological conditions from low to moderate winds. Comparison of the SAR-derived wind fields with those provided by satellite scatterometers indicates a good score of success (roughly 70%–80%). The developed methodology, once tested over an adequate number of images to derive statistically reliable results, could be routinely used to enrich SAR images with the wind field as well as to characterize the MABL in terms of size, distribution, and shape of the backscatter cells.
Characteristic-based Design of an LCC Resonant Converter with a Capacitive Filter
Authors: Sengupta Arkadeb , Kundu Utsab , John Vinod
Published: July 2023

 The LCC resonant converter with a capacitive output filter is a popular topology for variable load applications, though the simultaneous design requirements of wide load range, soft switching, and low conduction loss are not clearly tackled in available design strategies. In this paper, the existing time-domain analysis of the converter is extended in a normalized design-oriented fashion. The proposed extension to boundary modes lends itself to the derivation of critical converter characteristics such as the soft switching range. A dimensionless converter and load characteristic-based design algorithm with parameter decoupling is developed to meet the load requirements. The design algorithm reduces converter rms current while meeting practical requirements of zero voltage switching and constraints on switching frequency across the load range. The proposed design method is validated using circuit simulations incorporating series dissipative non-idealities and the transformer magnetizing inductance, and also on a 160 W laboratory prototype with switching frequency within the designated limits and $>$96$\%$ experimental efficiency.

Published: July 2023

This research focuses on the use of AI-powered badminton video analysis to enhance gameplay analysis and training. The technology utilizes artificial intelligence and machine learning algorithms to analyze varJaccard Similarity Index aspects of badminton game footage, including player movements, shot selection, and game strategy. It provides personalized feedback and recommendations for improvement to players and helps coaches identify patterns and trends in their players' performance.

The use of lightweight models, such as YoloV5, is essential for real-time video analysis due to the need for high-speed processing. These models, including MobileNets, EfficientNets, SqueezeNet, ShuffleNet, and Tiny-YOLO, are designed to be lightweight and optimized for speed while maintaining high accuracy.

The Yolo model, a one-shot learning model, is particularly suitable for real-time object detection tasks due to its impressive speed and accuracy. It uses anchor boxes and data augmentation techniques to quickly learn and recognize objects with a high level of accuracy.

The research process involved the collection of badminton match videos, preparation of datasets, and testing of the YoloV5 model's performance. Precision and Jaccard Similarity Index metrics using Jaccard similarity were used to evaluate the model's performance in detecting player positions and court boundaries.

The results showed that the YoloV5 model performed better when tested on the video data with less clear image of judges in the background. The Jaccard Similarity Index metrics using Jaccard similarity demonstrated improved performance when tested on generalized video data  was used to accurately evaluate the overlap between predicted and ground truth

Overall, AI-powered badminton video analysis has the potential to revolutionize the way badminton is played and coached. The use of lightweight models like YoloV5 enables faster and more efficient real-time analysis, making it practical for a wide range of applications in badminton.

An OFDM based waveform for delay Doppler domain communication
Authors: Gopalam Swaroop , Pillai Sibiraj , Whiting Philip , Inaltekin Hazer , Collings Iain , Hanly Stephen
Published: July 2023

This paper presents a new OFDM based modulation scheme for communication in doubly dispersive channels. We call this Delay-Doppler OFDM (DD-OFDM). Our waveform has the same sparse-channel benefits as orthogonal-time-frequency-space (OTFS) modulation, while offering advantages in terms of simpler channel estimation and lower out-of-band (OOB) emissions. We propose a DD-OFDM modulation scheme by introducing precoding across frames of frequency sub-carriers. We show that the resulting waveform has different data carrying basis functions compared to OTFS modulation. We present the DD-OFDM receiver and derive the base-band model equations. We show that the base- band model for DD-OFDM leads to a simple and accurate channel estimation algorithm in non-integer fractional Doppler channels.
Spatio-Temporal Associative Memories in Brain-inspired Spiking Neural Networks: Concepts and Perspectives
Authors: Kasabov Nikola
Published: July 2023

The paper introduces the main principles of spatio-temporal associative memory (STAM) inspired by learning principles in the human brain and implemented on a brain -inspired spiking neural network (SNN) architecture. A STAM is a machine learning model that is trained on a full set of spatio-temporal variables, but can be successfully recalled on only a subset of the variables measured in different time intervals. In addition, a STAM model can be further incrementally trained on a new subset of variables measured at varying times. STAM is based on spatio-temporal learning (STL), where existing spatial or other relevant information from the data is used to structure a SNN model and then temporal information is used to train the model. The model captures evolvable and explainable spatio/specro temporal patterns. A STAM model is validated through the introduced association- and generalization accuracy. Departing from traditional deep neural networks and machine learning methods, where trained models can only be recalled or incrementally trained on the same set of variables using vector-based representation, STAM opens the field of machine intelligence for the development of large-scale global spatio-temporal models that can be recalled and used locally, within the available local spatio-temporal data. Possible applications for STAM include: biological and brain signals; audio-visual data; seismic sensory data; financial and economic data; and other.

This may be dangerous for students using ChatGPT v3.5 as an assistant in their studies of Computer Science and Engineering and should be therefore used carefully. 
Surface Virus Inactivation by Non-Thermal Plasma Flow Reactor
Authors: Tang Anthony , Ong Angelo , Beck Nicola , Meschke John S. , Novosselov Igor V.
Published: July 2023

Infectious viruses can survive on surfaces for hours; they can be responsible for the fomite transmission mechanism of many diseases. We report the development and evaluation of a compact non-thermal plasma (NTP) flow reactor and its application for disinfection of surfaces. The concentric flow reactor produces a high concentration of reactive species by ionizing air flow passed through the reactor; the ionized jet exiting the reactor is impinged on the surface, exposing pathogens to high concentrations of reactive oxygen and nitrogen species. The reactor performance is characterized by measuring ozone concentration for various geometries and operating conditions. The ozone concentration reaches saturation at the exit for electrical power input above 100 W. The approach was tested for the inactivation of MS2 bacteriophage on surfaces with varied exposure times. We observed a 1.3 log reduction in viable virus counts at the exposure of 30 s and a 5.3 log reduction at 120 s exposure. The ozone production rates suggest that the reactor can be scaled to operate at higher flow rates, producing a concentration of reactive species sufficient for virus inactivation. 
ASFNet: Audio Spectrogram Fourier Network for Efficient Medical Sound Event Detection
Authors: HASSAN K. M. NAIMUL , Haque Mohammad Ariful
Published: July 2023

Sound event detection (SED) in the medical environment can be helpful in accomplishing different healthcare tasks. Due to the success of transformer encoder architectures for sound event detection, they seem to be a promising choice for detecting audio events in hospital settings. However, there are two main difficulties in detecting medical audio events with transformers. Firstly, the availability of medical audio data is extremely limited, making it difficult to effectively train a transformer model. Secondly, it is necessary for the SED model to be computationally efficient in order to be deployed in medical environments with limited resources. But, the transformer has high computational complexity because of the attention mechanism. To address these challenges, this paper introduces the Audio Spectrogram Fourier Network (ASFNet), a novel attention-free transformer encoder designed specifically for sound event detection in the medical environment. ASFNet replaces the attention operation with a simplified Fast Fourier Transform. By leveraging this approach, ASFNet outperforms the other methods, achieving a superior average mAP of 0.474 with a 16.76% relative improvement. ASFNet achieves this performance with fewer model parameters and smaller model size, making it an efficient and effective solution for medical audio event detection.

Scaling Hosting Capacity Analysis for Large Electrical Distribution Systems
Authors: Pizzimbone Luca
Published: July 2023

The rapid growth of renewable generation, driven by increasing concerns about climate change, sustainable energy sources, and energy independence, has presented significant challenges for distribution system operators (DSOs). Integrating intermittent sources while ensuring grid stability and reliability demands a robust evaluation of hosting capacity (HC) in power distribution networks. However, prevailing HC analysis methodologies predominantly rely on conservative assumptions or worst-case scenarios, often leading to impractical and unreliable outcomes. Commercial tools, though offer readily available solutions for hosting capacity analysis, suffer from limitations as they typically assess HC of individual nodes independently or focus on only a few distributed scenarios.

More elaborate methods have been proposed, attempting to cope with the complexity and stochastic nature of the HC problem. However, no much consideration has been given to their scalability to large distribution systems.

In response to the complexity and stochastic nature of the HC problem, this paper introduces an efficient methodology based on stochastic power system simulations and statistical analysis. The proposed approach undergoes comprehensive assessments to substantiate its efficacy, with a key focus on validating its accuracy for reliable HC estimates. Utilizing the bootstrap method, a resampling technique, multiple samples are generated to mimic possible Distributed Energy Resources (DERs) deployments, enabling estimation of confidence intervals for HC metrics. 

By applying statistical analysis to power system simulation results, insights into the expected variability and uncertainty of the problem are gained. These insights guide the selection of the minimum number of DER deployment scenarios necessary to ensure an efficient and well-informed HC assessment process.

The proposed methodology effectively addresses the challenges of HC analysis, offering scalability to large distribution networks. Its efficiency and enhanced accuracy make it a valuable tool for DSOs in facilitating the integration of renewable generation in a dependable and practical manner.

We present the case of a 50-year-old woman who underwent a CT scan of the chest as part of a surveillance examination during which a congenital anomaly of the branches of the aortic arch was discovered. It was a bicarotid trunk associated with an aberrant right subclavian artery, with no other abnormal vascular arrangement. This rare type of anomaly is usually discovered in childhood or when symptoms appear. Our patient had no knowledge of an episode of dyspnea-type respiratory disorder or dysphagia-type digestive disorder. This anomaly had never been reported to him. Educating clinicians about this anomaly is important for cardiologists and interventional radiologists given the growing number of cases.

Introduction: Two hundred outpatients were recruited for the study only sixty-five (65) of them were used from those who presented for bladder ultrasound. Masmed F5 4D ultrasound machine with a curvilinear transducer at 3.5MHz of frequency was used for the study. Pre and post void urinary bladder volume, anterior and posterior bladder wall thickness measurements were made on 65 healthy asymptomatic outpatients. There was no statistically significant difference between anterior and posterior bladder wall thickness (P>0.05) however there was a statistical significant difference between pre-void and post-void urine volume (P<0.05). Females were more prevalent in the study population than males with higher bladder wall thickness (BWT) consistent with lower urinary tract infection, the sonographic prevalence of urinary bladder retention was 8(12.31%), consisting of a male (1.54%) and females 7(10.77%) In line with bladder outlet obstruction (BOO) assessed at 5% level of significance. The sonographic prevalence of lower urinary tract infection in Biosensors medical diagnostics Wuse ll Abuja was 32.5% when assessed at the 5% level of in-significance (P>0.05), and it was most prevalent in individuals between the ages of 26 and 30. In Nigeria, it is advised that lower urinary tract infections should be diagnosed and treated early in both males and females.

Background: Pneumonia is described as an inflammation of the lung parenchyma. 1 Pneumonia is a major cause of illness and death in children worldwide, particularly in children under the age of five. Moreover, Preventive zinc supplementation may repair any deficiency that leads to immunodeficiency, and some data showed that it may lower child mortality and morbidity from infectious illnesses, including diarrhoea and pneumonia. Objective: In this study our main goal is to evaluate the efficacy of zinc supplementation as adjuvant therapy for severe pneumonia in young children. Method: This case control observational study was carried out at Tertiary medical college and hospital from June 2020 to 2021 among 200 young children aged <2 months to 5 years suffering from pneumonia. The participants were randomly assigned, following simple randomization procedures (1: 1), to receive zinc or placebo (5 mL every 12 hours) along with the common antibiotic treatments until discharge, was considered as a zinc supplement group, n=100. Patient assigned to placebo received the same solution as zinc supplement syrup but without zinc, which was considered as a non-zinc group, n=100. Results: During the study, maximum numbers of study group were in the age group 6 months to 2 years (56%) and (52%). Plus, in both group majority were male. In both group cough complaints was common, 100%. In zinc therapy group all had fever and hurried breathing and 9.6% had cold. Where as in non-zinc group all had cough followed by 90.4% had fever, 95.2% had hurried breath, 23.8% had cold. In zinc supplement group about 47.60% children had oxygen saturation less than 90 at the time of admission whereas about 53.30% children had oxygen saturation higher than 90 at the time. in zinc supplementation group mean time for resolution of distress was 52.45±33.98, mean time to be asymptomatic was 64.52±36.03, mean duration of hospital stay was 6.10±3.55.. whereas in non-zinc group mean time for resolution of .....
Association between Plasma Homocysteine Level and Atherogenic Index of Plasma among Hypothyroid Patients - A Case-Control Study
Authors: Abrar Dr. Bushra
Published: July 2023

Introduction: Hypothyroidism is a common metabolic disorder in general population. Hypothyroidism is a commonly encountered health problem in Bangladesh and morbidity and mortality toll due to cardiovascular disease resulting from hypothyroidism is quite high. Hypothyroidism, dyslipidaemia and hyperhomocysteinemia are recognized risk factor for atherosclerosis and cardiovascular disease. Aim of the Study: The aim of this study was to evaluate the association between plasma Homocysteine level and atherogenic Index of plasma in patients with hypothyroidism. Methods: This was a case-control study and conducted in the Department of Biochemistry in cooperation with Department of Endocrinology, Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh during the period from January, 2012 to December, 2013. In our study, we included 60 newly diagnosed hypothyroid individuals as case and 60 euthyroid individuals as control. Result: In this study, most of the participants were female (62%) compared to male (38%) and we found the mean age of the case and control group was 34.31 ± 11.77 years and 32.42 ± 12.51 years. Mean serum homocysteine was found significantly higher in case group (19.00 ± 7.58 µmol/L) than control group (9.59 ± 1.91µmol/L).Mean AIP was found significantly higher in case (0.75 ± 0.27) than control (0.35 ± 0.20). We found 49 (81.67%) cases were within increased risk group of atherogenesis where as in control group it was 28 (46.67%).In present study, mild hyperhomocysteinemia was found in 80% cases and moderate hyperhomocysteinemia in 13.3% cases where as in control group it was 10% & 0% respectively. Conclusion: In this study, we found that total plasma homocysteine level was significantly increased in recently diagnosed hypothyroidism and was normal in control groups. We also found that hypothyroidism is associated with high atherogenic index and hyperhomocysteinemia which causes premature atherosclerosis.

Introduction: Vitamin D deficiency is a global health issue, with children being particularly vulnerable. This study aimed to assess the prevalence and risk factors of Vitamin D deficiency among children attending a pediatric consultation center in Mohammadpur, Dhaka, Bangladesh. Methods: This observational study was conducted at a Pediatric Consultation Center in Mohammadpur, Dhaka, Bangladesh, from March 2022 to February 2023. The study population consisted of a total of 100 children aged <18 years who visited the center during the study period. Result: The results indicated a substantial prevalence of Vitamin D deficiency (40%) and insufficiency (52%) among the participants. The deficiency was observed to escalate with age, with the highest prevalence (32.50%) in the 12-16 years age group. Dietary evaluation revealed that 72% of participants had a poor intake of Vitamin D. Limited sun exposure was reported by 51% of participants, while 35% led an indoor lifestyle. Socioeconomic analysis revealed that 28% of participants belonged to a low socioeconomic status, which was identified as a risk factor for Vitamin D deficiency. Conclusion: The findings underscore the urgent need for public health interventions to improve the Vitamin D status of children in this population. Such interventions should include promoting the consumption of Vitamin D-rich foods, encouraging outdoor activities, and providing Vitamin D supplements where necessary. Regular monitoring of Vitamin D levels, particularly in children from low socioeconomic backgrounds, is crucial.
