Alzheimer Disease (AD) is the ordinary type of dementia which does not have any proper and efficient medication. Accurate classification and detection of AD helps to diagnose AD in an earlier stage, for that purpose machine learning and deep learning techniques are used in AD detection which observers both normal and abnormal brain and accurately detect AD in an early. For accurate detection of AD, we proposed a novel approach for detecting AD using MRI images. The proposed work includes three processes such as tri-level pre-processing, swin transfer based segmentation, and multi-scale feature pyramid fusion module-based AD detection.In pre-processing, noises are removed from the MRI images using Hybrid Kuan Filter and Improved Frost Filter (HKIF) algorithm, skull stripping is performed by Geodesic Active Contour (GAC) algorithm which removes the non-brain tissues that increases detection accuracy. Here, bias field correction is performed by Expectation-Maximization (EM) algorithm which removes the intensity non-uniformity. After completed pre-processing, we initiate segmentation process using Swin Transformer based Segmentation using Modified U-Net and Generative Adversarial Network (ST-MUNet) algorithm which segments the gray matter, white matter, and cerebrospinal fluid from the brain images by considering cortical thickness, color, texture, and boundary information which increases segmentation accuracy. After that, multi-scale feature extraction is performed by Multi-Scale Feature Pyramid Fusion Module using VGG16 (MSFP-VGG16) which extract the features in multi-scale which increases the detection and classification accuracy, based on the extracted features the brain image is classified into three classes such as Alzheimer Disease (AD), Mild Cognitive Impairment, and Normal. The simulation of this research is conducted by Matlab R2020a simulation tool, and the performance of this research is evaluated by ADNI dataset in terms of accuracy, specificity, sensitivity, confusion matrix, and positive predictive value.

Il aborde ensuite la question des précautions éthiques prises au cours de la collecte des données puis lors de leur présentation, en se concentrant sur le moment de la demande d’autorisation de filmer (consentement éclairé) et sur les procédés d’anonymisation des images tirées des vidéos. Ces réflexions se basent sur l’expérience d’une recherche menée à Beyrouth dans une association de soutien aux femmes migrantes et précaires.
Le dilemme de la recherche
Authors: Jouin Émilie , Ticca Anna Claudia
Published: April 2023

Cette contribution vise à mettre en lumière les enjeux éthiques et déontologiques qui découlent de la recherche en linguistique interactionnelle avec des publics précaires et/ou vulnérables dans des contextes de communication plurilingue. Au regard des enjeux liés à la protection de ces publics et des données sensibles qui résultent de ces situations (secret médical, récits de vie traumatisants, statuts juridiques irréguliers…), un certain nombre de mesures légales sont mises en œuvre afin que le travail de terrain et la collecte de données se réalisent en accord avec ces mesures. Cependant, face à la réalité du terrain, les chercheur·e·s tentent en permanence de faire coïncider des intérêts parfois discordants – ceux de la recherche, des avancées scientifiques et des retombées sociétales – et ceux des individus et de leur protection. Afin d’illustrer les difficultés qui jalonnent nos recherches, nous présentons nos expériences issues de terrains au Mexique et en France.

Authors: Cordovil Karen , Hada Masato , Francesco Zagami , Al-Harthi Adil , Musa Taha Hussein
Published: April 2023

Sarcopenia is a generalized loss of muscle mass affecting muscle function and strength with age. The cause of sarcopenia is multifactorial and physiopathological mechanisms, including the decline of neuron numbers, changes in muscle metabolism, oxidative damage, reduced response to nutrients, and inflammation throughout proinflammatory cytokines that increase myofibrillar protein degradation and decrease protein synthesis. This chapter presents two case reports about sarcopenia and its associated multimorbidity impact on elderly patients. Sarcopenia in the elderly, when it advances to generalized muscle wasting, is mainly associated with multimorbidity which becomes a diagnostic, therapeutic, and palliative challenge to the physician; in these cases, a multidisciplinary approach is best for appropriate diagnosis and management results in a high-quality patient care setting.

Authors: da Bernarda Luis , Santos Leonel , Costa Rogério L. C. , Rabadão Carlos
Published: April 2023

The technological development observed in recent years has led to the expansion of automotive systems communication capabilities. Consequently, several security vulnerabilities and additional attack surfaces that a threat agent can potentially exploit are increased. The most employed communication protocol in a vehicle is the controller area network (CAN) serial bus protocol, designed with robust fault tolerance in mind, but little to no concern for security. This chapter offers a primer on the controller area network typical architecture, what messages are used in communication, its error management system, and its vulnerabilities. Possible CAN attack surfaces and attack methods are also presented, followed by an exposition on intrusion detection systems (IDS) as a potential solution to the security concerns raised by CAN bus vulnerabilities. Several case studies on IDS implementations for secure CAN bus systems are also presented, including a recently proposed framework to facilitate further development in this field of study.

Exploring accountability of individuals in the mining sector: A multi-level perspective
Authors: Brandling Tarryn , Pearson Hayley , Mthombeni Morris
Published: April 2023

Purpose: In heavy industries like mining, where safety is paramount, organisations need a well-functioning system of accountability. Yet to whom employees perceive they are accountable differs at varying hierarchical levels. This article reports on the findings from a study that investigated sources of accountability at different organisational levels in a certain mining operation and the mechanisms used to manage such accountability.Design/methodology/approach: An exploratory, qualitative research methodology was used in the study, underpinned by in-depth interviews with participants from three organisational levels: blue-collar workers, supervisors and managers. The data collected were analysed using thematic content analysis.Findings/results: Blue-collar workers and supervisors considered self-accountability and accountability to line managers to be the primary sources of accountability. However, managers stressed the importance of accountability to regulatory bodies and the legal implications of non-adherence to prescribed standards. All participants perceived their reputations to be heavily dependent on their accountability relationships. Mechanisms used in the organisation to promote accountability included clarifying roles and responsibilities, building open and honest interpersonal relationships, implementing standardised policies and procedures, and offering financial incentives.Practical implications: The findings from the study informed the development of a conceptual accountability model, which should help mining executives in other organisations to manage the accountability process and promote responsible and safe behaviour at all organisational levels.Originality/value: There is limited empirical research on sources of accountability in organisations. This study provides useful insights that help to fill this gap.

Published: April 2023

Background:

The job demands of some of the industries have been reported to be hazardous to the health and safety of workers. Workplace environmental hazards or occupational hazards are a globally major cause of disability and mortality among the working population. The present study was done to analyze the effect of exposure to metal dust on pulmonary function and respiratory symptoms.

Materials and Methods:

The study population selected as cases were 200 male mill workers working for at least 1-year duration (direct exposure) in the age group of 20–50 years, and controls were 200 age- and gender-matched male participants without any history of occupational or environmental exposure. A complete history was taken. Spirometry was done. Spirometric parameters studied were forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), ratio of FEV1 and FVC, and peak expiratory flow rate (PEFR). The spirometry data and baseline characteristics of the participants were compared using unpaired t-test.

Results:

The mean age of the participants of the study group and the control group was 42.3 years and 44.1 years, respectively. The majority of the study population belonged to the age group of 41–50 years. The mean FEV1 value among participants of the study group and control group was 2.69 and 2.13, respectively. The mean FVC value among participants of the study group and control group was 3.18 and 3.63, respectively. The mean FEV1/FVC value among participants of the study group and control group was 84.59% and 86.22%, respectively. The mean PEFR value among the study group and control group was 7.78 and 8.67, respectively. While analyzing statistically, mean lung functional tests were significantly lowered among the study group. About 69.5% of the participants of the study group thought it to be essential for making safety measures a necessity.

Background:

Identification of drug-related problems (DRPs) is a medication management service that can add value to individual patient care. Determination of DRPs daily is a promising approach for optimizing treatment.

Objective:

The objective of this study was to analyze the incidence of DRPs identified along with the risk factors that contribute to its development.

Setting:

This study was conducted in a tertiary care hospital in Central Kerala, India.

Methods:

A cross-sectional study was conducted among 300 newly admitted patients to the general medicine department. Patient medical records were reviewed in 3 stages – medication reconciliation, medication order review, and discharge summary review, and DRPs were categorized based on the Pharmaceutical Care Network Europe V9.1. Patient characteristics such as age, gender, polypharmacy, comorbidities, nonadherence, and type of illness were recorded.

Results:

Out of 300 patients, 78.7% had DRPs. The incidence of DRPs was found to be 0.26 cases/people-months. Although age >60 years, gender, polypharmacy, nonadherence, comorbidities, and chronic ailments were risk factors for DRPs, only polypharmacy and comorbidities could be proven statistically.

Conclusion:

DRPs are an emerging issue within the confines of the health-care system and should be scrutinized to avoid negative outcomes. A stage-wise analysis of patients who are at risk will ensure better patient care.

The purpose of this study was to evaluate the severe acute respiratory syndrome coronavirus 2 antibodies response in COVID-19 patients and health-care providers to them in different categories and with respect to age, sex, and symptoms.

Materials and Methods:

Analysis of immunoglobulin (Ig) G and total COVID antibodies was done by chemiluminescent microparticle immunoassay (CMIA) and IgM antibodies by rapid card test method in 300 cases.

Results:

Out of 300 cases, asymptomatic were 29%, mild 26.66%, moderate 17.66%, and severe were 28.33%; percentage of males were higher than females in all. The most common age group involved was 30–40 years (20%). The most common symptom was fever (51.33%), followed by cough (38.66%), and the most common comorbidity was hypertension (16.33%). We observed that severe category had a higher percentage of symptoms as well as comorbidities. Out of 300 cases, 56.66% were IgG positive, and 89.6% were total COVID antibody positive. In rapid IgM antibodies, out of 50 cases, 13 were positive. We observed that IgM was positive mainly in severe cases compared to mild cases, while IgG level was lower in severe cases than those of mild cases. In our study, majority of cases (97 cases) are IgG positive approximately in 8–14 days after onset of symptoms.

Conclusion:

Quantitative analysis of antibodies is a simple, quick, and cheap method and could play major role in diagnosis and prognosis of COVID-19, and also used to pick up silent carriers (asymptomatic patients) who missed in false-negative reverse transcription polymerase chain reaction in such epidemic.
Diagnostic dilemma in a case of neonatal cardiac tumor – The importance of histopathology and mutation analysis in clinical practice
Authors: Sardar Syamal , Dey Rakesh , Mukherjee Suchandra , Pal Somnath
Published: April 2023

Fetal or neonatal cardiac tumors are rarely encountered in neonatal practice. Moreover, these can be the earliest manifestation of underlying systemic conditions, such as tuberous sclerosis. Cardiac tumors are primarily diagnosed by characteristic findings in transthoracic echocardiography. However, these findings are not absolute, and histopathology remains the gold standard in diagnosing cardiac tumors. Sometimes, doubtful imaging findings can delay the diagnosis and initiation of definitive management. We describe a case of fetal and neonatal cardiac tumor where histopathology served as a benchmark in making a diagnosis and helped in identifying the underlying systemic disease.

Published: April 2023

This study aimed to explore the effects of PPAPDC1A on the malignant phenotype of breast cancer (BC) in vivo and in vitro. PPAPDC1A expression was examined in BC tissues and cell lines by real-time polymerase chain reaction and Western blot. In this article, cell proliferation was evaluated by Cell Counting Kit-8 assay and colony formation assay, and cell migration and invasion were evaluated by wound healing assay and transwell assays. Furthermore, in vivo cell growth and pulmonary metastasis experiments were also performed using nude mice. The results showed that compared with normal tissues and cells, the PPAPDC1A expression in BC tissues and cell lines were both significantly increased. The PPAPDC1A targeting sequence significantly inhibited the PPAPDC1A expression and cell proliferation, migration, and invasion. The results of xenograft showed that knockdown of PPAPDC1A inhibited tumor growth and lung metastasis of BC. Then, the Dual-Luciferase Reporter Assay confirmed that miR-598-5p targeted the regulation of PPAPDC1A expression. In addition, the miR-598-5p expression in BC tissues was lower than that in the normal tissues. The rescue experiment showed that PPAPDC1A overexpression reversed the inhibitory effect of miR-598-5p mimic on cell proliferation, migration, and invasion. In conclusion, PPAPDC1A was highly expressed in BC tissues and cell lines, and miR-598-5p inhibited the malignant phenotype of BC by targeting PPAPDC1A.
Review of hierarchical database access control for E-medicine systems
Authors: Lee Tian-Fu , Wang Jyun-Guo , Chen Yen-Chang
Published: April 2023

ABSTRACT

Key management schemes for hierarchical access control enable users who have hierarchical relationships with each other to manage their secret keys efficiently. In these schemes, the users are divided into several groups, and all groups have their own central authorities. Each central authority is responsible for setting parameters and generating user’s secret keys in a hierarchical structure such that all users efficiently derive their secret keys and solve dynamic access control problems. Several key management schemes with Health Insurance Portability Accountability Act regulations were recently proposed for hierarchical access control in e-medicine systems. However, these schemes either are insecure or require a large amount of storage and heavy computations. Therefore, this study reviews and discusses hierarchical access control schemes with privacy/security regulations for medical record databases.
Favorable Immunotherapy Plus Tyrosine Kinase Inhibition Outcome of Renal Cell Carcinoma Patients with Low CDK5 Expression
Authors: Xu Xianglai , Wang Ying , Chen Zhaoyi , Zhu Yanjun , Wang Jiajun , Guo Jianming
Published: April 2023

Purpose Immunotherapy (IO) plus tyrosine kinase inhibitor (TKI) has become the first-line treatment for advanced renal cell carcinoma, despite the lack of prognostic biomarkers. Cyclin-dependent kinase 5 (CDK5) affects the tumor microenvironment, which may influence the efficacy of TKI+IO.Materials and Methods Two cohorts from our center (Zhongshan Metastatic Renal Cell Carcinoma [ZS-MRCC] cohort, Zhongshan High-risk Localized Renal Cell Carcinoma [ZS-HRRCC] cohort) and one cohort from a clinical trial (JAVELIN-101) were enrolled. The expression of CDK5 of each sample was determined by RNA sequencing. Immune infiltration and T cell function were evaluated by flow cytometry and immunohistochemistry. Response and progression-free survival (PFS) were set as primary endpoints.Results Patients of low CDK5 expression showed higher objective response rate (60.0% vs. 23.3%) and longer PFS in both cohorts (ZS-MRCC cohort, p=0.014; JAVELIN-101 cohort, p=0.040). CDK5 expression was enhanced in non-responders (p < 0.05). In the ZS-HRRCC cohort, CDK5 was associated with decreased tumor-infiltrating CD8+ T cells, which was proved by immunohistochemistry (p < 0.05) and flow cytometry (Spearman’s ρ=–0.49, p < 0.001). In the high CDK5 subgroup, CD8+ T cells revealed a dysfunction phenotype with decreased granzyme B, and more regulatory T cells were identified. A predictive score was further constructed by random forest, involving CDK5 and T cell exhaustion features. The RFscore was also validated in both cohorts. By utilizing the model, more patients might be distinguished from the overall cohort. Additionally, only in the low RFscore did TKI+IO outperform TKI monotherapy.Conclusion High-CDK5 expression was associated with immunosuppression and TKI+IO resistance. RFscore based on CDK5 may be utilized as a biomarker to determine the optimal treatment strategy.

Authors: Ezeiza Ainhoa
Published: April 2023

Si bien la web 2.0 se ha visto superada por las redes sociales, en esta investigación se propone retomar los foros virtuales para desarrollar la competencia comunicativa académica universitaria, ya que estos pueden generar un contexto sociodiscursivo real y, asimismo, permiten aprender comparando los textos propios con los de otros estudiantes. Para conocer cómo diseñar tareas comunicativas para estudiantes bilingües (lengua castellana y vasca) de primer curso del grado de Educación Primaria, en la primera fase de este estudio (567 estudiantes), se identificaron las tareas más significativas por su correlación con los resultados de aprendizaje. En la segunda fase (141 estudiantes), se analizó el impacto de una retroalimentación docente y entre iguales, de manera rápida y personalizada. Como resultado, destaca que una selección empíricamente contrastada de tareas comunicativas, que incluyen retroalimentación por pares, mejora los resultados de aprendizaje; además, reduce la carga de trabajo, al eliminar aquellas tareas poco significativas.

Journey of Realization and Adaptation through Auto/Ethnography: A Shift to Transformative Educational Research
Authors: Paudel Tara , Luitel Bal Chandra , Dahal Niroj
Published: April 2023

This reflective paper explores Tara's doctoral research journey of realization and adaptation in auto/ethnography as a transformative research methodology. While reflecting on Tara’s journey, the auto/ethnographic paper emphasizes cultural perspectives, interpreting one's own experiences, thoughts, actions, and behaviors relating to society and culture. Likewise, auto/ethnography investigates and associates an individual's confrontation within specific educational, societal, and cultural contexts. With this ethos, the paper demonstrates how Tara, a mathematics teacher and doctoral student, encountered and observed auto/ethnography and discovered it as a path to transformation as a paradigm shift in transformative educational research by connecting lives and research (Dahal et al., 2022) considering the basis of ethics in auto/ethnography (Dahal & Luitel, 2022). Next, in this scenario of residing in cultural and societal context dealing with Tara’s emotions and settings of an education system, we have explored the journey of realization and adaption on how auto/ethnography blends analytic, evocative, and performative realms. Overall, we also realized that auto/ethnography guided us to delve through the past, present, and possible future experiences and unlatch Tara’s eyes to visualize a new era of research for upcoming generations in teaching and learning mathematics that reaches out to society and the nation whilst shifting to transformative educational research.
The Differences of the Calcium Hydroxide and the Mineral Trioxide Aggregate in the Apical Closure of Immature, Non-Vital Permanent Teeth
Authors:   Dean of Faculty and lecturer, Stomatology Faculty, Rokhan Institute of Higher Education, Jalalabad City, Afghanistan., Habib Fazlullah , Salamzai Ali Mohammad ,   Lecturer of the Clinic Department, Stomatology Faculty, Rokhan institute of higher education
Published: April 2023

When an immature tooth comes into contact with trauma, the dental pulp in the developing tooth can die, which can cause the absence of root and apical closure. Apexification is a technique used to repair these abnormalities. This method allows us to promote the growth of a hardened root end block. MTA and Ca (OH)2 are two materials that can be used in this process. Either MTA or calcium hydroxide have a good chance of producing positive clinical results. MTA is favored over calcium hydroxide for its significantly shorter time for apical barrier formation, low solubility, easy approach, and ability to prevent root fracture, while calcium hydroxide is preferred over MTA for root length elongation in open apex teeth. The limitations of calcium hydroxide include the fact that it takes more time and multiple visits to form the root-end barrier, is more prone to fracture, and has the potential for reinfection. The goal of this review is to collect revisions on inducing root formation and synthetic barrier approaches and consider the advantages and disadvantages of calcium hydroxide versus MTA.

Published: April 2023

This is a qualitative case study that explores how social capital optimizes the power of human capital in enhancing government performance and realizing broader goals and objectives that benefit an entire country. Through the analysis of data pertaining to the Republic of Armenia, the study explores approaches to growing social capital to boost the power of human capital in the government. As such, the research reveals that several work dynamics contribute to growing social capital, among which reciprocal collaboration, idea exchanges, and socialization; shared values of mutual trust and respect among staff; enabling environment of learning, openness, and healthy competition; sense of ownership, teamwork, and team performance rewards; sense of belonging and regard for national goals across units of government; and elimination of political favoritisms among staff. Though many of these notions are discussed in separate works by social science theorists, this qualitative research bundles multiple strategies in a comprehensive discussion of building social capital within and among units of government that would measurably amplify human capacity and performance for the public good.

The objective of this study is to identify the explanatory determinants of success of a crowdfunding campaign in Cameroon. By adopting a qualitative approach, we carried out semi-structured interviews with 4 managers of SMEs that had carried out a crowdfunding campaign. The analysis were made using the Nvivo 10 software, it appears firstly that the inherence characteristics of the project constitute the major determinant of the success of a campaign. Secondly, after analyzing the speeches of the interviewees, it emerges that identity of proximity does not influence contributions during a campaign. Finally, it appears that the current institutional framework is not adequate for crowdfunding, it does not constitute a guarantee for potential investors.
Huffman Encoding with White Tailed Eagle Algorithm-based Image Steganography Technique
Authors: Alkhliwi Sultan
Published: April 2023

Since the Internet is a medium for transporting sensitive data, the privacy of the message transported has become a major concern. Image steganography has become a prominent tool for hiding data to ensure privacy during transfer. An efficient steganography system is essential to accomplish the best embedding capacity and maintain the other parameters at a satisfying level. Image encryption systems provide a secure and flexible system to maintain the privacy of image conversion and storage in the transmission system. Many existing image steganography methods can be attacked by various techniques, or do not support many image formats for embedding. To resolve these shortcomings, this study presents the Huffman Encoding with White Tailed Eagle Algorithm-based Image Steganography (HEWTEA-IS) technique, aiming to achieve secrecy with no compromise in image quality. The HEWTEA-IS method uses Discrete Wavelet Transform (DWT) for the decomposition of images into different subbands, and Huffman encoding to determine the embedding bits on the decomposed blocks and offer an additional layer of security. Moreover, the WTEA resolves the problem of imperceptibility by identifying the optimal probable position in the cover image for embedding secret bits. The proposed algorithm was simulated and examined in terms of different measures, and an extensive experimental analysis ensured that it is superior to other methods in several aspects.
An Experimental Study on the Effect of Plastic Waste Powder on the Strength Parameters of Tuff and Bentonite Soils Treated with Cement
Authors: Sellaf Hamid , Balegh Benamar
Published: April 2023

This experimental study investigated the effect of plastic waste powder on the strength and swelling behavior of tuff and bentonite soils treated by cement since the plastic powder is highly compressible and does not absorb much water. This study aimed to improve the tuff and bentonite soils used in construction by adding plastic waste powder in various ratios (5, 10, 20, and 25%) and a low cement content (2.5%). Atterberg limit, swelling consolidation, and loading-unloading tests were performed to determine the optimal composition of the mixture. The results demonstrated that as the plastic powder content increases, the liquid limits, swelling pressure, swelling potentials, and duration to swelling peak decrease. This reduction is particularly notable for the soil with the highest swelling potential. Compression and recompression indices increase significantly with the content of plastic powder due to its high compressibility. The findings suggest that plastic powder with low cement can be utilized as a soil modification reinforcement material, but with a content that shouldn't significantly alter the compressibility of the mixture.

This paper presents a new of economic and environmental study of a hybrid system (wind turbine and diesel generator) in Algerian desert regions using HOMER software. The principal interests of the hybrid system are clean production at the place of consumption, the combined use of resources, energy storage, and supply security. Using an experimental device outfitted with Homer software, models were developed and successfully compared to reality. The obtained results confirm that the proposed system proved to be accurate enough to distinguish energy transfers and fast enough to enable optimizing the sizing and handling of the system's energy transfers. The purpose of this paper is to confirm the robustness of the HOMER software and to check the technical, economic, and environmental criteria of the integrated system.

The prediction of grain yield is important for sowing, cultivar positioning, crop management, and public policy. This study aims to predict maize productivity by applying an artificial neural network and by building models of multilayer perceptrons (MLPs) using public data and maize experimental networks. The dataset included parameters of climate, soil water balance, and agronomic characteristics from maize hybrids of an experimental network of two agricultural years. The climatic and soil balance water parameters were divided according to the maize plant development stages. Six databases were obtained by combining the imputation of missing data with the agronomic characteristics of the maize hybrids, the climatic parameters/soil water balance, and the complete database with both. Hyper parameterization of the models was obtained using GridSearch and k-fold cross-validation. The models with imputation were more accurate than those without it. The model with climate data/soil water balance and the complete model with imputation presented the smallest errors of 71 kg ha−1. In all the models, cultivars, locations, and their interactions were important, and different climatic conditions had the greatest weight in predicting productivity. It was concluded that the MLP models performed adequately and captured the non-linear effects of the interaction between the environment and maize hybrids. Climatic and soil balance water parameters at different stages of maize plant development explain the productivity of maize hybrids more than the agronomic characteristics of the cultivars.

The current study focuses on disclosing the types and causes of traffic events in the Sulaymaniyah governorate and their association with driver implications. The study was conducted between September 2019 and August 2020 in cooperation with the General Directorate of Traffic. A total of 573 traffic accident forms were directly collected at the site of crush events. The result shows that the collision type of Road Traffic Accidents (RTAs) is the most frequent type, accounting for 64.6% of the total. Higher incidence of RTAs was recorded in pickup, taxi, and motorcycle automobiles than in private cars. The analysis showed that the driver's faults are responsible for 81.4% of RTAs followed by road issues, mechanical car faults, and environmental factors which were responsible for 15%, 2.4%, and 1.2%, respectively. The most important driver factors accountable for RTAs were overspeeding, low level of education, gender, young age, and alcohol intake. Driver age group 19-33 is highly associated with RTAs with the peak occurring at the age of 21 years.
Computation of Limit Loads for Bending Plates
Authors: Tran Trung-Dung , Vo Nguyen Phu-Huan
Published: April 2023

The purpose of this paper is to present a method for calculating the upper bound limit loads of plate bending using a conforming Hsieh-Clough-Tocher (HCT) element. These limit loads can be obtained from Koiter’s kinematic shakedown theorem for the case of one load vertex instead of using the kinematic limit theorem. When combining this theorem with the approximated displacement field, the limit analysis turns into an optimization problem and can be effectively solved by Second-Order Cone Programming (SOCP). Several benchmark plate problems such as square, rectangular, and L-shape plates are investigated to illustrate the effectiveness of the proposed solution. The results of the proposed method show good agreement with the results of previous studies. The maximum error is only 2.91% for the fully clamped rectangular plate problem.

Falcon is an efficient and secure postquantum signature scheme for services based on quantum computing. It employs the hash-and-sign approach in conjunction with the Gentry, Peikert, and Vaikuntanathan (GPV) framework on Number Theory Research Unit (NTRU) lattices. This study evaluated the operation procedure and the capacity to run the Falcon scheme using a key length of 1024 bits on different hardware and software platforms, such as personal computers and Raspberry Pi 4 and Windows, Ubuntu, and Android operating systems. The following results were obtained: file sizes ranged from 30 to 5449268 KB, digital signature times ranged from 50 to 19500ms, and signature verification times ranged from 14 to 19000ms. The results show that the Falcon post-quantum signature scheme works stably and ensures execution speed on different platforms, similar to current digital signature schemes.

This paper presents the effect of the curing environment on the unconfined compressive strength of soil-cement samples and in finding the optimum output mix ratio and estimating the effect of silica fume in the admixture. This work is based on the data from the Cai Mep-Thi Vai inter-port road project and results from laboratory experiments. The results show that the specimens with the highest strength were cured in soil, lowered in city water with NaCl 2.5% and then NaCl 5%. The optimum silica fume admixture ratio equals to 1% (in comparison with the weight of cement content).
