Authors: Yablokov N. O. , Krivolutskiy D. A. , Klunduk A. V. 
Published: August 2023

The aim of the research is to evaluate the structural and biological parameters of the spawning stock of the turukhanskaya form of the Siberian vendace Coregonus sardinella (Valenciennes, 1848) from the Yenisei River and the state of the commercial stock of this fish species in the period from 2014 to 2021. Research methods: in the research used the ichthyological material collected in the period from 2014 to 2021 in the lower reaches of the Yenisei River (near the Dudinka town and the village of Levinsky Sands). Processing of ichthyological materials was carried out according to generally accepted methods. The number of spawning herds of Siberian vendace was calculated using a virtual population analysis in Galland’s modification. Instant natural mortality rates by age groups were calculated using the method of L. A. Zykov. Results: According to the control catches, the age of the spawning stock of the turukhanskaya form of Siberian vendace in the Yenisei River was 2+–9+ years. Fish aged 4+ years, which in different years constituted from 47 to 68 % of the spawning stock, dominated in the population. The average long-term age of the spawning population in the study period was 4.2 years. The ratio of females and males in the spawning herd was close to 1:1 on average. Individual absolute fecundity of fishes varied in the range from 1.9 to 12.5 thousand eggs, increasing with increasing age and size of females. The average population fecundity is 2.6–5.3 thousand eggs. The number and biomass of the spawning herd in different years varied from 11.0 to 30.5 thousand individuals and from 630 to 1738 tons, respectively. Practical significance: the obtained results about the dynamics and structure of the spawning stock of the semi-anadromous form of the Siberian vendace from Yenisei River for the period from 2014 to 2021 will be used for prognostic purposes in the preparation of materials substantiating the volumes of the recommended catch in the basin of the Yenisei River. Conclusion: Based on the results of the analysis of the age, size-weight and sex structure, it was shown that the state of stocks of the semi-anadromous turukhanskaya form of the Siberian vendace in the Yenisei River is currently in a satisfactory condition.

Published: August 2023

<p>Decentralized ledger technology (DLT) is becoming ubiquitous in today's society. After an initial grassroots adoption, enterprises embrace this technology, following the opportunity to expand to new businesses - the technology is maturing. However, organizations need to connect their existing systems and processes to blockchains (centralized - decentralized) securely and reliably, sometimes also implying to connect blockchains (decentralized - decentralized). This challenge is known as blockchain interoperability.</p>
<p>Blockchain interoperability comes in three modes: data transfers, asset transfers, and asset exchanges. As blockchain interoperability is still maturing, there are many unsolved challenges across the different interoperability modes. In this \emph{position paper}, we illustrate the remaining challenges of interoperability, focusing on the systematic evaluation of interoperability mechanisms, based on the state of the art and our own experience. We first introduce the notion of cross-chain interoperability and cross-chain rules. Then, we present our survey and results. </p>
<p>We ran an online survey comprised of 17 items targeting blockchain specialists. Our quantitative analysis shows that several interesting metrics can show promising directions to evaluate integration solutions systematically. Finally, building upon our study, we propose the blockchain interoperability evaluation framework, the first step to evaluate blockchain interoperability solutions systematically.</p>
Enhancing SSVEP Identification with Less Individual Calibration Data Using Periodically Repeated Component Analysis
Authors: Ke Yufeng , Liu Shuang , Ming Dong 
Published: August 2023

<p> Spatial filtering and template matching-based methods are commonly used to identify the stimulus frequency from multichannel EEG signals in steady-state visually evoked potentials (SSVEP)-based brain-computer interfaces (BCIs). However, these methods require sufficient calibration data to obtain reliable spatial filters and SSVEP templates, and they underperform in SSVEP identification with small-sample-size calibration data, especially when a single trial of data is available for each stimulus frequency. In contrast to the state-of-the-art task-related component analysis (TRCA)-based methods, which construct spatial filters and SSVEP templates based on the inter-trial task-related components in SSVEP, this study proposes a method called periodically repeated component analysis (PRCA), which constructs spatial filters to maximize the reproducibility across periods and constructs synthetic SSVEP templates by replicating the periodically repeated components (PRCs). We also introduced PRCs into two improved variants of TRCA. Performance evaluation was conducted using a self-collected 16-target dataset and a public 40-target dataset. The proposed methods show significant improvements with less training data and can achieve comparable performance to the baseline methods with 5 trials by using 2 or 3 training trials. Using a single trial of calibration data for each frequency, the PRCA-based methods achieved the highest average accuracies of over 95% and 90% with a 1-s data length and maximum average information transfer rates of 198.8±57.3 bits/min and 191.2±48.1 bits/min for the two data sets, respectively. Our results demonstrate the effectiveness and robustness of PRCA-based methods for SSVEP identification with reduced calibration effort and suggest its potential for practical applications of SSVEP-BCIs. </p>
DAG Blockchain-based Personalized Federated Mutual learning in Internet of Vehicles
Authors: Wu Yuhang , Huang Xiaoge , Yin Hongbo , Liang Chengchao , Chen Qianbin 
Published: August 2023

<p> Federated learning (FL) emerges as a distributed training method in the Internet of Vehicles (IoVs), allowing connected and automated vehicles (CAVs) to train a global model by exchanging models instead of raw data, protecting data privacy. Due to the limitation of model accuracy and communication overhead in FL, in this paper, we propose a directed acyclic graph (DAG) blockchain-based IoV that comprises a DAG layer and a CAV layer for model sharing and training, respectively. Furthermore, a DAG blockchain-based asynchronous federated mutual learning (DAFML) algorithm is introduced to improve the model performance, which utilizes a student-teacher model in the local training and a mutual distillation method that enables models to be partially updated using mutual transferred knowledge. Moreover, to further improve the model accuracy, the personalized weight is designed to adjust the mutual distillation in the model updating. Simulation results demonstrate that the proposed DAFML algorithm outperforms other benchmarks in terms of the model accuracy and distillation ratio.</p>

Authors: Shahid Mohammad Zeshaan , Osman Dalia , Noh Yohan 
Published: August 2023

<p>This paper presents the development and implementation of a low-cost, portable scale utilizing a smartphone and image processing technology. The main objective of this research is to explore the potential of using a compliant mechanism, markers, and image processing techniques to accurately determine the weight of an object. We designed a 3D printed platform fitted with a webcam to capture images of white markers on a black surface. The Image Processing Toolbox on MATLAB was used to detect two parameters, the number of white pixels and the centroid positions of the white pixels with respect to the centre of the image in each marker. Calibration is carried out to convert these two parameters into weight, hence accurately estimating the weight of an object placed on the platform. </p>
Autoencoder-based Spatial Modulation for the Next Generation of Wireless Networks

Published: August 2023

<p>Spatial Modulation (SM) has been proposed as a multiple-input-multiple-output (MIMO)-based technique to overcome the inter-channel interference experienced in conventional MIMO systems. It has been further shown that SM enhances energy efficiency and reduces the receiver’s complexity. Nevertheless, under high antenna correlation scenarios, the detection performance of the antenna indices degrades significantly. To address this critical concern, in this paper, we propose three autoencoder-based frameworks for spatial modulation. The first scenario, similar to conventional spatial modulation, trains the encoder for data modulation and the decoder for data demodulation as well as antenna index detection. The performance of this framework deteriorates in high antenna correlation scenarios. Therefore, two novel solutions are presented to embed the antenna index into the transmitted signal in order to reduce the receiver’s reliance on the channel conditions. The first framework adds a phase-shift keying-based antenna signature, while the other trains the encoder to learn an appropriate antenna index embedding. Simulation results show that the two enhanced frameworks result in a significantly enhanced performance, compared to conventional spatial modulation, in terms of block error rate and power efficiency under a high correlation setup (about 18 dB and 24 dB gain, respectively, at a Rician factor of 20 dB).</p>
A Simplified and Comprehensive Space Vector Pulse Width Modulation (SVPWM) for Multilevel Inverters
Authors: Ostadrahimi Amir 
Published: August 2023

<p>Despite numerous advantages of space vector pulse width modulation (SVPWM) methods, their implementation on multilevel inverters (MLI) is onerous. Due to the ever-increasing use of MLIs in power electronic applications, it is essential to implement efficient modulation procedures aiming to keep control sampling periods sufficiently short. This paper proposes a straightforward SVPWM Strategy, which uses algebraic functions throughout the procedure and avoids using hardware-consuming trigonometric functions. Look-up tables and region detection are no more necessary. It also generates switching states automatically, without requiring any data in advance. As another simplification, the proposed SVPWM is only designed for the first sector, instead of six sectors of the space vector modulation (SVM) plane. This simplification is done via <i>transferring</i> and <i>translating</i> techniques. Regardless of the number of voltage levels, the proposed SVPWM strategy is comprehensively applicable to any <i>n</i>-level three-phase inverters, without any major modification. Simulation and experimental results attest to the authenticity and effectiveness of the proposed SVPWM. As the supplementary materials of this research, MATLAB simulation files are provided together with the manuscript.</p>

Authors: Carreiro Gabriela Alves , Arcoverde Gustavo Felipe Balué , Barros Jocilene Dantas 
Published: August 2023

Este estudo consiste na análise espacial de degradação da terra, com objetivo de identificar padrões espaciais de tendência à baixa resposta hidro-vegetacional em pastagens nos biomas Cerrado e Caatinga entre os anos 2000 a 2018. Os padrões foram avaliados por meio da metodologia para proxy de degradação utilizando-se a razão de produtividade líquida (PPL) e a precipitação que resultou no índice rain use efficiency – RUE. Este índice constitui um indicador de degradação para zonas áridas, semiáridas e subúmido. Os resultados obtidos por meio da metodologia abordada foram linhas de padrão de tendência de resposta hidro-vegetacional – endmember e dois mapas de classificação de tendências de processos degradativos, logo os resultados podem apresentar falsos negativos e uma validação em campo se faz necessária.
Trinta Anos de Geografia Política no PPGG: Balanço e Perspectivas
Authors: De Castro Iná Elias 
Published: August 2023

Este texto traz a experiência de 3 anos de geografia política no PPGG como parte da comemoração dos seus 50 anos. A liberdade de escolha da grade temática das disciplinas e das pesquisas dos estudantes e a tolerância entre os colegas do Programa são marcas que têm aberto a possibilidade aos professores de definir novos conteúdos para seus campos de conhecimento com diferentes matrizes teóricas, conceituais e metodológicas. Esse pluralismo beneficiou a ideia de desenvolver estudos numa geografia política informada pelas bases conceituais da política, tomada aqui no seu sentido teórico, institucional e empírico. A abordagem teórica da ciência política como balizamento para questões da geografia política conduziu a temas, autores, discussões teóricas e pesquisas que, de modo surpreendente, apresentavam afinidades com aqueles da geografia e possibilitavam ampliar o escopo de análise e debates na disciplina. A criação do GEOPPOL – Grupo de Estudos e Pesquisas sobre Política e Território fortaleceu a geografia política, acolheu estudantes e formou profissionais que hoje atuam em diferentes instituições e estão presentes em universidades de diferentes partes do país. A maioria das teses e dissertações foram publicadas e tornaram-se referências para outros estudantes de outros programas de pós-graduação. A partir do PPGG e do Geoppol temos hoje uma rede de trocas com colegas que lideram pesquisas em geografia política em estados da Região Nordeste – Pernambuco, Paraíba, Bahia e Ceará –, em Brasília, na UnB e no Ministério da Ciência e Tecnologia, no Paraná e em instituições do Rio de Janeiro.

Authors: Moreira Gomes Francisco Carlos , Lapa Diogo Parreira , Zaidan Ricardo Tavares 
Published: August 2023

A região serrana do estado do Rio de Janeiro passa por diversas questões ambientais que transitam dos escorregamentos de terra às inundações, a recorrência desses eventos é marcada por prejuízos e mortes anualmente. Esse trabalho tem sua motivação central na aplicação de uma metodologia para a análise do risco de inundação, utilizando-se de alguns planos de informação espacial de fácil acesso e/ou elaboração. A metodologia se deu em três etapas (obtenção de dados, elaboração de parâmetros e validação), e constatou que os locais na sub-bacia do rio Paquequer com o maior risco a inundações são aqueles ocupados pelo núcleo central da cidade. Assim, foi possível mensurar as áreas de risco à inundação de modo preliminar, com planos de informação relativamente simples de serem gerados. Considera-se então que a metodologia aplicada é uma alternativa para municípios menores, com reduzida capacidade de investimento, para fomentar análises mais robustas de risco à inundação.

Intestinal malrotation clinical approach in adult patients.
Authors: Ovejero Gómez VJ , Bermúdez García MV , Pérez Martín A , Morales García D 
Published: August 2023

Resumen

La malrotación intestinal es un proceso congénito que afecta a la fijación final del tracto intestinal generando malfunción intestinal. Sus manifestaciones clínicas graves son más frecuentes en la edad pediátrica. Su diagnóstico en el adulto suele ser casual o asociado a episodios no específicos de dolor abdominal que podrían evolucionar a volvulación y fenómenos isquémicos sobre segmentos intestinales dependientes de la arteria mesentérica superior, llegando a comprometer la vida del paciente.

Exponemos nuestra experiencia en dos pacientes con diagnóstico confirmado de malrotación intestinal a fin de incrementar el conocimiento en esta patología, poco definida en pacientes asintomáticos.

Se ha realizado una revisión de los aspectos clínicos más relevantes a partir de su naturaleza embriológica y las tendencias terapéuticas actuales. Enfatizamos la importancia de incluir este cuadro en el diagnóstico diferencial del dolor abdominal recurrente acompañado de alteraciones del tránsito intestinal, y la necesidad de nuevas estrategias de tratamiento que reduzcan el riesgo de recidiva y aporten calidad de vida.
