Published: October 2023

We Present a new architecture of the 3D SAG wireless access networks for uplink communication between IoRT and LEO satellite, utilizing several multi-antenna UAV relays. The most important structural features of this network are as follows:

1) Due to the prominence of multi-antenna systems technology as a promising solution to achieve advanced telecommunication systems, multi-antenna UAV relays are considered in our system model. These relays have the capability to communicate with each other using singular value decomposition (SVD) beamforming technique.

2) To control the number of remote connections, only selected UAVs act as gateways to connect to the satellite.

3) The proposed architecture incorporates FSO space communication links to address limitations of the RF spectrum resource and achieve higher data rates for air-space links.

We formulate a new joint optimization problem of gateway selection, channel allocation, UAV deployment, and UAV power allocation for multi-tier communication in order to minimize the weighted sum of the number of  gateways and the total UAV power consumption. Our proposed solution includes a two-step approach using constrained k-means clustering for channel allocation between IoRT devices and UAVs, and UAV location, and an algorithm inspired by simulated annealing (SA) for gateway selection, channel allocation between UAVs and gateways, and UAV transmit power optimization. The UAV power optimization is solved using the successive convex approximation (SCA) method.

Various simulations are performed to evaluate the performance of the proposed system model and the proposed optimization schemes. The results demonstrate the effectiveness of our proposed scheme in achieving optimal clustering, UAV deployment, and gateway selection. The required number of gateways for different scenarios is also determined. Notably, by implementing the SA algorithm to jointly optimize UAV transmit power, gateway selection, and UAV to gateway channel allocation, our proposed scheme achieves an average performance improvement of 48% compared to the case where only clustering is performed. The results also highlight the impact of the number of UAVs and the number of their antennas on the system performance.

Authors: Nguyen Quoc , Le Trung , Nguyen Thang , Nguyen Nhat Minh
Published: October 2023

The demand for precise brain tumor detection and analysis in cancer diagnosis and treatment has escalated, necessitating extensive and diverse medical datasets. However, the acquisition of labeled tumor images is impeded by intricate dissimilarities between tumor and non-tumor regions, compounded by the diverse spectrum of brain tumor types. This study addresses a critical research gap by proposing a novel approach for robust and trustworthy brain tumor MRI image synthesis. Leveraging label conditional diffusion models, our approach adeptly captures specific tumor features, resulting in the generation of high-quality tumor images. Additionally, a trustworthiness control mechanism, employing evaluation metrics such as Fréchet Inception Distance (FID) and Inception Score (IS), ensures generated MRI brain tumor images meet exacting quality, accuracy, and clinical relevance criteria. Despite potential limitations in sharpness due to resolution constraints, our framework excels in overcoming challenges posed by image similarities and variations in brain tumor images. This surpasses the performance of conditional generative adversarial networks (GANs) by producing realistic details and textures. This contribution significantly advances the field of brain tumor image synthesis.
Integration of Fiber Tracts in Anatomically Accurate Brain Models during Transcranial Magnetic Stimulation
Authors: Lewis Connor , Harris Connor , Mittal Neil , Peterson Carrie , Hadimani Ravi
Published: October 2023

Transcranial magnetic stimulation (TMS) is a noninvasive brain stimulation technique used in the treatment of several neurological conditions. The dosage parameter for TMS protocols is the resting motor threshold (RMT) which has been shown to vary between participants with limited understanding. The goal of this study was to investigate how white matter-derived fiber tracts integrated into finite element analysis simulations influence TMS response in the form of RMT. Ten healthy participants were included in this study who underwent TMS, diffusion tensor imaging, and structural magnetic resonance imaging (MRI). Anatomically accurate head models were created and fiber tracts were extracted from Diffusion tensor imaging and integrated into these head models before finite element analysis simulations were performed to model the effects of empirical TMS. Linear mixed effects models were used to evaluate how the induced electric field strength on the fiber tracts (EFSTract) influenced RMT. We found the induced electric field strength along fiber tracts did influence RMT, however the effect of this relationship on RMT is not clinically relevant due to its small magnitude. This suggests finite element analysis of the fiber tracts is not meaningful when tracts are considered a homogenous material and thus lacking physiology. However, tractography provides a valuable framework within which to organize physiological models of signal transmission, and it is likely a combination of this approach with more physiologically detailed modeling would provide more accurate RMT prediction. 
Exploring Bias in the FOLD-R++ Algorithm: A Comprehensive Analysis
Authors: Ramamoorthy Raaghav
Published: October 2023

As machine learning is being used in numerous applications, there is even more concern regarding algorithms within artificial intelligence. This paper focuses on analyzing the biases incorporated in a setup like FOLD-R++. The findings hold significance to both academia and industry in establishing what a fair and neutral machine learning algorithm is. The article contains an exhaustive literature review about biases in machine learning and a detailed explication. The chapter re-examines previous studies on the efficacy of this algorithm, unearthing the limitations in earlier literature and urging more research.This involves purposefully choosing a dataset from Kaggle, metrics applied in evaluating the algorithm, and a detailed experimental design. The results of these tests of different test scenarios have displayed that the algorithm is correct but vulnerable to bias and efficient across different domains. The results are discussed, and comparisons with what is available in the table regarding system-biased algorithms are made. In conclusion, this study contributes to the existing literature on machine learning and highlights certain shortcomings concerning the use of the FOLD-R++ algorithm. Thus, it demonstrates the need to address issues of unexplained inequality and develop reliable algorithms for decision-making. The study acknowledges these shortcomings to the extent that it becomes a vital stage toward developing more justified machine learning.
Low-Complexity Compressed Sensing-Aided Coherent Direction-of-Arrival Estimation for Large-Scale Lens Antenna Array
Authors: Hoang Trong Dai , Huang Xiaojing , Qin Peiyuan
Published: October 2023

This paper delves into a novel compressed sensing (CS) strategy for estimating the directions of incoming signals in a coherent environment using a lens antenna array (LAA). In comparison to the well-known subspace-based algorithm family, CS techniques, such as the conventional orthogonal matching pursuit (COMP), can effectively address the direction-of-arrival (DoA) estimation problem requiring prior knowledge about the number of signals and offer lower complexity. However, they are susceptible to noise and can be adversely affected by multipath distortion. Leveraging the energy-concentrating property of an LAA, we first introduce the signal covariance matrix-based OMP (SCM-OMP) method that enhances the angular estimation performance, even in low-SNR regions. Subsequently, we propose the multiple sub-covariance matrices-based OMP (MSCM-OMP) to achieve a reduction in computational complexity. Simulation results demonstrate that the MSCM-OMP scheme also outperforms other high-resolution DoA estimation methods.

ACIDENTE VASCULAR ENCEFÁLICO E USO DA ESCALA NIHSS
Authors: Moreira do Amaral Diogo , Fernandes Luciana
Published: October 2023

O Acidente Vascular Encefálico (AVE) é um problema mundial. Pode ser definido como um déficit neurológico causado, de forma abrupta, pela interrupção do fluxo sanguíneo para o cérebro, de modo isquêmico ou hemorrágico. O AVE isquêmico representa cerca de 80% desses acontecimentos, sendo o mais prevalente e incidente no Brasil. Estima-se que cerca de 15 milhões de pessoas são acometidas por ano e dessas 5 milhões evoluem para óbito. A agressividade dessa patologia faz com que seja uma das principais causas de morte no mundo gerando custos elevados, cerca de 0,66% do PIB global. A escala NIHSS, desenvolvida na década de 80, sofreu alterações no ano de 2004 para melhor utilidade diante da realidade brasileira e é aceita como potencial modificadora do cuidado ofertado para pacientes pós-AVE. O objetivo deste estudo foi realizar uma revisão breve da literatura sobre a aplicabilidade da escala NIHSS em pacientes pós-AVE. Para elaboração deste estudo utilizou-se de bases de dados como SciELO, MEDLINE/PubMED e LILACS. A análise dos dados evidenciou que, mesmo com a existência de programas de combate aos fatores que predispõe a essa patologia, a incidência dessa enfermidade poderá aumentar nos próximos anos e a escala NIHSS, embora tenha sido programada para auxiliar em pesquisas, é aceita como exame clínico mais eficaz para quantificar o déficit neurológico causado por esse agravo. A escala também se mostrou eficiente para determinar o melhor tratamento por permitir, de forma rápida, 5 a 8 minutos a compreensão do estado atual do paciente: quanto a progressão do déficit neurológico. Um fator importante para a aplicação da escala, é a capacitação dos profissionais que pode ser realizada on-line, todavia, deve-se ter cautela ao aplicá-la, pois esta ferramenta foi elaborada para fins de pesquisa.

Authors: Bindah Eric
Published: October 2023

In this book, an assessment of psychometric properties of scales used in consumer behaviour research is made. It looks into the study area of factors that are most likely to influence individuals to consume product and services. An evaluation of various instruments commonly utilized by researchers and academics in this field of research is discussed. The book contains eight units and explores several concepts and theories in the area of consumer socialization before making an evaluation of the different research instruments. Psychometric properties refer to the validity and reliability of the measurement tool. Before being able to state that a questionnaire has excellent psychometric properties, meaning a scale is both reliable and valid, it must be evaluated extensively, hence leading to its importance in research. The purpose of this book is to provide some insights and assessment of various instruments commonly used by researchers in the area of consumer behaviour, which ultimately leads to consumption among consumers. In order for the reader to be able to apply the basic ideas of psychometric theory to actual data sets of relevance, this book aims to introduce such ideas. Its goal is not to turn readers to become measurement experts, but rather to give them the confidence and knowledge they need to better understand and participate in the research process.

Violencia de género en los trayectos cotidianos en transporte urbano en el Área Metropolitana de Monterrey
Authors: Soto Canales Karina
Published: October 2023

Las investigaciones cualitativas generadas en torno a la movilidad cotidiana y los usuarios del transporte urbano, son escasas; el presente documento pretende señalar, desde lo individual, el amplio espectro conductual (exclusión, dominación, control) con respecto de la violencia de género en los trayectos cotidianos de las usuarias del transporte público del Área Metropolitana de Monterrey (AMM[1]). La metodología utilizada define algunas características que tipifican este campo socioespacial a través de entrevistas a profundidad e historias de vida de mujeres, con las cuales se recuperan percepciones tangibles e intangibles de las usuarias, lo que permite que mediante el análisis de contenido (clasificación y análisis de las experiencias), establecer tres categorías predominantes sobre el fenómeno de estudio: horarios (predictibilidad), percepción y vestimenta. Finalmente, se reflexiona sobre las prácticas de dominación, control y subordinación en la ciudad (calle, parabús y el camión) como obstáculo para la utilización y ocupación justa del espacio urbano, como derecho a la ciudad; los hallazgos a su vez, sugieren nuevas posibilidades para el abordaje del tema, así como la redelimitación del universo de estudio en función a otras caracterizaciones (etarias, actividades económicas, solo por mencionar algunos).

Herein, we investigate the mixture of methylammonium lead iodide (MAPbI3) and formamidinium lead iodide (FAPbI3). The perovskite films were coated onto fluorine-doped tin oxide (FTO) glass substrates using a spin-coating method, with the spin-coater set at 4,000 rpm for 20 s. We studied the influence of incorporation in MA(1-x) FA(x)PbI3 films. The crystal structure of the perovskite films was characterized using X-ray diffraction (XRD). Optical properties were assessed using UV-Vis spectroscopy with a spectrophotometer, and photoluminescence (PL) was characterized using a He-Cd Si-CCD laser source and a Hamamatsu detector. Images depicting the characteristic morphology of the films were captured with a scanning electron microscope (SEM). Our measurements reveal that the crystallinity of the MAPbI3 thin film improved with the incorporation of FAPbI3. In the case of 70% FAPbI3, the morphology of the MA30FA70PbI3 mixture also improved, exhibiting a rough surface with pores. The optical properties were enhanced, and the mixed thin film demonstrated better stability compared to pure MAPbI3 and FAPbI3 thin films. These film characteristics indicate that the mixtures are particularly suitable for use in photovoltaic applications.

Published: October 2023

A flexible manufacturing system (FMS) is an integral part of a smart factory of Industry 4.0 in which every machine is interconnected and works autonomously. Robots are in the process of replacing humans in every industrial sector. As the cyber-physical system (CPS) and artificial intelligence (AI) are advancing, the manufacturing industry is getting more dependent on computers than human brains. This modernization has boosted production with high quality and accuracy and shifted from classic production to smart manufacturing systems. However, workpiece handling for such an automated production system is a challenge and needs to be addressed with the best possible solution. Conventional clamping systems are designed for manual work and are not suitable for highly automated production lines. Researchers and engineers are trying to find the most economical solution for loading/unloading and transportation of workpieces from a warehouse to a machine shop for machining operations and back to the warehouse without human involvement. This work aims to propose an advanced multi-shape tooling solution for highly automated manufacturing systems. The currently obtained result shows that it could function well with automated guided vehicles (AGVs) and modern conveyor belts. The proposed solution is following requirements to be automation-friendly, and universal for different part geometry and production operations. We used a bottom-up approach in this work, starting with studying different case scenarios and their limitations and finishing with the general solution.

Published: October 2023

To meet the growing energy needs of the world’s population, international governments have turned to biomass energy from agricultural waste as a form of renewable energy. To this end, this study is based on the experimental and practical determination of certain physicochemical properties of three agricultural residues (cocoa cortex, oil palm fibres and sugar cane bagasse) using approximate and structural analysis methods. Then, using a METERK electronic detector, the small quantities of CO2 emitted during combustion in 0.5 g boilers of each of these waste products used to produce energy (heat and/or electricity) were determined. The gross and net calorific values of these biomasses were also determined. Here are some of the results obtained for these three agricultural residues: variable moisture content (from 3.6% to 43.12%), variable organic matter content (from 76.12% to 90.31%), cellulose content (from 32.74% to 55.91%), lignin content (from 8.26% to 27.05%), variable net calorific values (from 6.581 kWh/kg to 10.461 kWh/kg) and low CO2 gas emissions (from 439 ppm to 447 ppm). This proves that these three agricultural residues are very good potential sources of energy that can be used as fuel in boilers to produce large quantities of heat that can be converted into electricity by turbines connected to alternators using electromagnetic induction phenomena. Finally, this work provides credible information for public and private decision-makers in the field of electricity production from the combustion of these agricultural residues in boilers.
A Study on Satisfaction with Residential Welfare Services by Generation
Authors:   Korea Real Estate Society, Nam Young Woo
Published: October 2023

In Korea, the market environment has changed rapidly due to low birth rate and aging population.
Accordingly, there was a need for change in housing welfare policies centered on the homeless and low-income class. In Korea, with the announcement of the Housing Welfare Roadmap in 2017, housing welfare policies according to the life cycle are being pursued in earnest. Therefore, there is a need to evaluate satisfaction with housing welfare services and analyze influencing factors. In this study, based on a housing survey, awareness and satisfaction with housing welfare services were evaluated by generation according to the life cycle and influential factors were analyzed.
The results of the analysis showed that, except for loan services and housing supply, awareness of housing welfare services was low. In terms of satisfaction with housing welfare services, the overall level was found to be good. In the analysis of variance by generation for the evaluation of housing welfare services, significant differences in averages by generation were found. In an analysis of factors affecting satisfaction with housing welfare services, it was found that satisfaction was low when the household was headed by a female and the household size was small. As the area of the house increases, satisfaction with lease and purchase financing appears to decrease, but satisfaction with public housing appears to increase.
Considering these analysis results, it is necessary to actively promote housing welfare services according to the life cycle and continuously promote the development of differentiated welfare services by generation.
An exploratory study on the application of a work-integrated learning model in university: Focusing on real estate and tourism major
Authors:   Korea Real Estate Society, Jung Hae Yong
Published: October 2023

This study was conducted to develop a work-integrated learning model to intentionally link and integrate students' work experiences in future job sites and university curriculum, and to propose application plans focusing on real estate and tourism majors. To achieve this research purpose, theoretical and practical prior studies and domestic and foreign cases of work-integrated learning were reviewed, and based on this, a work-integrated learning model consisting of four types: a full-course integrated model, a specific area advanced model, a specific topic-oriented model, and a multi-process diversification model was proposed. Due to the nature of the major as a specific integrated learning application plan, the real estate major was presented as a specific topic-oriented model, and the tourism major was presented as a full-course integrated model. The implication of this study is that it presented a work-integrated learning model that can be implemented in universities and specific application plans centered on real estate and tourism majors. The limitation of this study is that there is no related research in Korea, so it is presented as an exploratory study, and future studies will require research on effective detailed program application and evaluation methods for each integrated learning model.

Intraductal papillary neoplasms of the bile duct (IPNBs) represent a rare variant of biliary tumors characterized by a papillary growth within the bile duct lumen. Since their first description in 2001, several classifications have been proposed, mainly based on histopathological, radiological and clinical features, although no specific guidelines addressing their management have been developed. Bile duct neoplasms generally develop through a multistep process, involving different precursor pathways, ranging from the initial lesion, detectable only microscopically, i.e. biliary intraepithelial neoplasia, to the distinctive grades of IPNB until the final stage represented by invasive cholangiocarcinoma. Complex and advanced investigations, mainly relying on magnetic resonance imaging (MRI) and cholangioscopy, are required to reach a correct diagnosis and to define an adequate bile duct mapping, which supports proper treatment. The recently introduced subclassifications of types 1 and 2 highlight the histopathological and clinical aspects of IPNB, as well as their natural evolution with a particular focus on prognosis and survival. Aggressive surgical resection, including hepatectomy, pancreaticoduodenectomy or both, represents the treatment of choice, yielding optimal results in terms of survival, although several endoscopic approaches have been described. IPNBs are newly recognized preinvasive neoplasms of the bile duct with high malignant potential. The novel subclassification of types 1 and 2 defines the histological and clinical aspects, prognosis and survival. Diagnosis is mainly based on MRI and cholangioscopy. Surgical resection represents the mainstay of treatment, although endoscopic resection is currently applied to nonsurgically fit patients. New frontiers in genetic research have identified the processes underlying the carcinogenesis of IPNB, to identify targeted therapies.
The Jena Audiovisual Stimuli of Morphed Emotional Pseudospeech (JAVMEPS): A database for emotional auditory-only, visual-only, and congruent and incongruent audiovisual voice and dynamic face stimuli with varying voice intensities
Authors: von Eiff Celina I. , Kauk Julian , Schweinberger Stefan R.
Published: October 2023

We describe JAVMEPS, an audiovisual (AV) database for emotional voice and dynamic face stimuli, with voices varying in emotional intensity. JAVMEPS includes 2256 stimulus files comprising (A) recordings of 12 speakers, speaking four bisyllabic pseudowords with six naturalistic induced basic emotions plus neutral, in auditory-only, visual-only, and congruent AV conditions. It furthermore comprises (B) caricatures (140%), original voices (100%), and anti-caricatures (60%) for happy, fearful, angry, sad, disgusted, and surprised voices for eight speakers and two pseudowords. Crucially, JAVMEPS contains (C) precisely time-synchronized congruent and incongruent AV (and corresponding auditory-only) stimuli with two emotions (anger, surprise), (C1) with original intensity (ten speakers, four pseudowords), (C2) and with graded AV congruence (implemented via five voice morph levels, from caricatures to anti-caricatures; eight speakers, two pseudowords). We collected classification data for Stimulus Set A from 22 normal-hearing listeners and four cochlear implant users, for two pseudowords, in auditory-only, visual-only, and AV conditions. Normal-hearing individuals showed good classification performance (McorrAV = .59 to .92), with classification rates in the auditory-only condition ≥ .38 correct (surprise: .67, anger: .51). Despite compromised vocal emotion perception, CI users performed above chance levels of .14 for auditory-only stimuli, with best rates for surprise (.31) and anger (.30). We anticipate JAVMEPS to become a useful open resource for researchers into auditory emotion perception, especially when adaptive testing or calibration of task difficulty is desirable. With its time-synchronized congruent and incongruent stimuli, JAVMEPS can also contribute to filling a gap in research regarding dynamic audiovisual integration of emotion perception via behavioral or neurophysiological recordings.

Human Immunodeficiency Virus - associated dementia (HAD) is a complex neurocognitive condition that affects the central nervous system of HIV-infected patients. This case highlights the importance of thorough clinical observation, neuroimaging, and multi-disciplinary medical investigations, for establishing an accurate diagnosis, therefore, providing the proper pharmacological/non-pharmacological treatment and therapies for the patients. This study will exhibit the clinical features of this disease, its course, and how it evolves over time. We aim to provide a detailed perspective on this condition, focusing on symptoms, diagnostic assessments, and proper patient management. Through this case, we aim to contribute and enhance the medical knowledge and therapeutic approaches, and to add an overall improvement to the management of HAD (HIV-associated dementia). We report the case of a young male patient, who was diagnosed with HAD, to draw attention to its presentation at an early age and the initial pathologic manifestation display. In the past, HIV-associated dementia mainly affected individuals in advanced stages of the disease, often among individuals with compromised immune systems. However, our case emphasizes the importance of HIV-associated dementia early assessment, regardless of age and even in the absence of other typical HIV-related symptoms. This highlights the need for health professionals to conduct thorough evaluations, regardless of the patient’s age when neurocognitive symptoms occur suddenly. By reporting this case, we aim to increase awareness among healthcare providers, regarding the increasing occurrence of HIV-associated dementia in young people, determining a precise diagnosis as early as possible, to acquire a better prognosis and a favorable evolution for the patient, as well as to improve his quality of life.

Published: October 2023

The placebo and nocebo effects are commonly understood as the patients’ responses to treatment in accordance with their positive or negative expectations, respectively, regarding their health. Such treatments involve substances or interventions with no known inherent effects on the studied condition, but which nonetheless may have a discernible effect on the condition’s presentation and evolution. Their influence on clinical outcomes confront practitioners with often underestimated therapeutic tools and challenges whose applicability are subject to ethical debate. Furthermore, placebos play a crucial part in our current understanding of therapeutic efficacy and in the development of novel interventions. This narrative review aims to present a brief exposition of the roles that placebo and nocebo effects play in psychiatric clinical practice and research.

Nudged Elastic Bands and Lightly Bound Skyrmions
Authors:   University of Leeds, UK, Speight James Martin , Winyard Thomas ,   University of Edinburgh, UK
Published: October 2023

It has become clear in recent years that the configuration space of the nuclear Skyrme model has, in each topological class, many almost degenerate local energy minima and that the number of such minima grows with the degree (or baryon number) $B$. Rigid body quantization, in which one quantizes motion on the spin-isospin orbit of just one minimum, is thus an ill-justified approximation. Instead, one should identify a (finite-dimensional) moduli space of configurations containing all local minima (for a given $B$) as well as fields interpolating smoothly between them. This paper proposes a systematic computational scheme for generating such a moduli space: one constructs an energy minimizing path between each pair of local minima, then defines the moduli space to be the union of spin-isospin orbits of points on the union of these curves, a principal bundle over a graph. The energy minimizing curves may be constructed in practice using the nudged elastic band method, a standard tool in mathematical chemistry for analyzing reaction paths and computing activation energies. To illustrate, we apply this scheme to the lightly bound Skyrme model in the point particle approximation, constructing the graphs for $5\leq B\leq 10$. We go on to complete the quantization for $B=7$, in which the graph has two vertices and a single edge. The low-lying quantum states with isospin $1/2$ do not strongly localize around either of the local energy minima (the vertices). Their energies rise monotonically with spin, conflicting with experimental data for Lithium-7.

The first record of the Darwin wasp, Cyrtorhyssa moellerii Bingham, 1898 (Hymenoptera, Ichneumonoidea, Rhyssinae) from Thailand is presented. Members of both sexes are fully described and illustrated. The biology of C. moellerii, a parasitoid of the pleasing fungus beetle Encaustes opaca Crotch, 1876 (Coleoptera, Erotylidae), is reported for the first time. Hosts were associated with standing deadwood of Anthoshorea henryana (Pierre ex Laness.) P. S. Ashton & J. Heck (Dipterocarpaceae) in dry evergreen forest, Nakhon Ratchasima province, northeastern Thailand. DNA barcodes (cytochrome c oxidase subunit 1 sequence (COI)) were generated for both host and parasitoid and phylogenetic trees constructed for these and other members of the same family and subfamily respectively. A key is provided to separate the three known species of Cyrtorhyssa. This is the first confirmed host record for a tropical species of Rhyssinae as well as the first from Erotylidae.
Singularités de la colonisation européenne
Authors: Etemad Bouda
Published: October 2023

Toutes les expériences d’expansion territoriale des grandes régions du monde donnent lieu à la domination d’un peuple par des conquérants d’une autre culture. Mais la colonisation européenne a ses singularités historiques : la recherche de la richesse et de la puissance, la hiérarchisation raciale, la fragilité de ses possessions et, enfin, son héritage épineux, du fait de l’émigration d’ex-sujets coloniaux vers les anciennes métropoles.
L’économie politique de la colonisation française des XIX e et XX e siècles
Authors: Cogneau Denis
Published: October 2023

Loin des idées reçues sur le coût de l’empire colonial, la doctrine s’imposa dès le début du XX e  siècle que cet empire devait rester « bon marché ». Or, si la colonisation fut en effet peu coûteuse pour le contribuable français, elle le fut bien plus pour le contribuable colonisé.
Paroles de prof. Faire travailler les élèves sur la question coloniale

Professeure de lettres-histoires en filière professionnelle au lycée Auguste Blanqui de Saint-Ouen (93), Laure Coret a fait travailler ses élèves de terminale sur la question coloniale, avec pour perspective la publication d’un article collectif dans Après-demain . Après une séquence de réflexion dense et documentée, menée sur plusieurs semaines, les élèves montrent qu’ils savent répondre aux attendus du diplôme, mais semblent éprouver des difficultés à faire coïncider histoire, récit de soi et « nous » à construire.
Cannabidiol for the Treatment of Pediatric Epilepsy
Authors: Daniel Jeremy
Published: October 2023

Pediatric epilepsy is a debilitating disease cluster that is much less researched than adult epilepsy. With approximately 30% of patients with pediatric epilepsy experiencing refractory seizures, novel treatment modalities are sometimes necessary to provide benefit. The use of marijuana, and more specifically cannabidiol, in people with seizures is much more broadly researched in adults compared with pediatric patients, although several recent review articles have been published. This article seeks to provide a pathophysiological basis for cannabidiol in epilepsy, discuss commercially available products and nonpharmaceutical marijuana, and review recent evidence in pediatric epilepsy.

Application of aggregated control functions for approximating $ \mathscr{C} $-Hilfer fractional differential equations
Authors: Aderyani Safoura Rezaei , Saadati Reza , O'Regan Donal , Alshammari Fehaid Salem
Published: October 2023

The main issue we are studying in this paper is that of aggregation maps, which refers to the process of combining various input values into a single output. We apply aggregated special maps on Mittag-Leffler-type functions in one parameter to get diverse approximation errors for fractional-order systems in Hilfer sense using an optimal method. Indeed, making use of various well-known special functions that are initially chosen, we establish a new class of matrix-valued fuzzy controllers to evaluate maximal stability and minimal error. An example is given to illustrate the numerical results by charts and tables.
The spillover effect of international monetary policy on China's financial market
Authors: Yang Cunyi , Chen Li , Mo Bin
Published: October 2023

This study analyzes the impact of global financial integration and monetary policies from the United States, European Union and Japan on China's financial markets post-pandemic. Using TVP-FAVAR (Time-Varying Parameter Factor Augmented Vector Autoregression) and TVP-VAR-DY (Time-Varying Parameter Vector Autoregression DY) models, a Chinese financial market stress index was developed, showing that developed nations' monetary policies influence China's financial stress. The impact varies based on the economy's size and policy effectiveness. The spillovers occur mainly through accelerated short-term capital flows and foreign exchange reserve fluctuations. These effects have evolved over two decades, particularly noticeable during economic crises and the COVID-19 pandemic, highlighting the need for emerging economies, like China, to protect against international financial spillovers.
Effective Brain Stroke Prediction with Deep Learning Model by Incorporating YOLO_5 and SSD
Authors: Sailaja Yanda , Pattani Velumurugan
Published: October 2023

Ischemic stroke is a life-threatening disorder that significantly reduces a person’s lifespan. The timely diagnosis of stroke heavily relies on medical imaging techniques such as magnetic resonance imaging (MRI), computerized tomography (CT), and x-ray imaging. However, the manual localization and analysis of these images can be time-consuming and yield less accurate results. To address this challenge, we propose the implementation of deep-learning object detection techniques for computerized lesion identification in medical images. In this study, we employ three categories of deep learning object identification networks: deep convolutional neural network (DCNN), you only look once (YOLO) 5, and single-shot detector (SSD). By leveraging these advanced deep learning models, we aim to reduce the effort and time required for screening and analyzing a significant number of daily medical images, including MRI, CT, and x-ray images. With the addition of YOLO5 and SSD among these networks, the accuracy achieved was 96.43%, demonstrating their effectiveness in accurately identifying lesions associated with ischemic stroke.

Authors: Phahlane Mampilo M.
Published: October 2023

Much like other governments in the world, the South African government through the Department of Public Service and Administration (DPSA) in collaboration with Government Information Technology Officer Council (GITOC) and the Auditor General (AG) has developed Corporate Governance of Information and Communication Technology Policy Framework (CGICTPF). CGICTPF is based on King III Code of Good Governance, ISO 38500 Standard for the Corporate Governance of ICT, and COBIT as a comprehensive Governance ICT Process Framework and is applicable to all spheres of government. The department of transport was also mandated to implement and use this framework as a government entity to improve the status of ICT government. The chapter is about how CGICTPF was implemented in the public sector using the Department of Transport as a case. Semi-structured open ended interviews data were collected with institutional theory as a lens. It is concluded that management support and proper organizational structures create positive outcomes in environments with high regulatory requirements.
