Event-triggered integral sliding mode control for uncertain networked linear control systems with quantization
Authors: Zhao Xinggui , Meng Bo , Wang Zhen
Published: August 2023

In this paper, the integral sliding mode (ISM, SM) controller is designed to address the problem of implementing non-periodic sampled data for a class of networked linear systems with matched and unmatched uncertainties. Due to the redesigned gain of the nominal controller, the feedback control used by the nominal controller guarantees the asymptotic stability of the uncertain networked linear system. The discontinuous control uses intermittent control based on the reaching law to achieve the finite-time reachability of practical SM band. Based on the defined measurement error, the event-triggered (ET) condition can be derived, and furthermore, it guarantees a sufficient condition for the existence of the actual SM. On this basis, a quantization scheme is added to further decrease the network transmission burden of the linear system. No Zeno behavior occurs in the system owing to the existence of a positive lower bound of inter-event time. Compared with the conventional integral sliding mode control (ISMC, SMC), the proposed control law can not only relieve the network burden, but also decrease the transmission energy loss. Finally, simulation results of a numerical example and a mass-spring damping system demonstrate the effectiveness of the proposed method.

Published: August 2023

In recent years, the global outbreak of COVID-19 has posed an extremely serious life-safety risk to humans, and in order to maximize the diagnostic efficiency of physicians, it is extremely valuable to investigate the methods of lesion segmentation in images of COVID-19. Aiming at the problems of existing deep learning models, such as low segmentation accuracy, poor model generalization performance, large model parameters and difficult deployment, we propose an UNet segmentation network integrating multi-scale attention for COVID-19 CT images. Specifically, the UNet network model is utilized as the base network, and the structure of multi-scale convolutional attention is proposed in the encoder stage to enhance the network's ability to capture multi-scale information. Second, a local channel attention module is proposed to extract spatial information by modeling local relationships to generate channel domain weights, to supplement detailed information about the target region to reduce information redundancy and to enhance important information. Moreover, the network model encoder segment uses the Meta-ACON activation function to avoid the overfitting phenomenon of the model and to improve the model's representational ability. A large number of experimental results on publicly available mixed data sets show that compared with the current mainstream image segmentation algorithms, the pro-posed method can more effectively improve the accuracy and generalization performance of COVID-19 lesions segmentation and provide help for medical diagnosis and analysis.

Published: August 2023

Introduction:

A good wettability of an endodontic sealer plays an important role in creating a fluid impervious seal within the root canal. The chelator employed during endodontic irrigation modifies the intraradicular dentin surface and alters the wettability of the sealer. Hence, the aim of the study is to evaluate and compare the effect of 17% ethylenediaminetetraacetic acid (EDTA), 7% maleic acid (MA), and 9% hydroxyethylidene diphosphonic acid (HEDP) on the wettability of CeraSeal and AH Plus sealers.

Materials and Methods:

Forty-four single rooted premolars were decoronated followed by longitudinal sectioning into 88 halves. They were randomly allocated into 4 groups (n = 22) based on the irrigation regimen: Group I (2.5% sodium hypochlorite [NaOCl] +17% EDTA), Group II (2.5% NaOCl + 7% MA), Group III (2.5% NaOCl + 9% HEDP) and Group IV (2.5% NaOCl + distilled water). Each group was subdivided into two subgroups (n = 11) according to the type of sealer employed: CeraSeal sealer and AH Plus sealer. The contact angle was measured using contact angle telescope goniometer. Comparison between the sealers for each group was done using independent t-test and multiple comparisons of irrigants and sealers in various combinations were done using Two-way Analysis of Variance (P < 0.05).

Results:

The wettability of CeraSeal sealer on intraradicular dentin was the most favorable when 9% HEDP was employed as the final irrigant, whereas the wettability of AH Plus sealer on intra radicular dentin was most favorable with 7% MA as the final irrigant. AH Plus sealer showed better wettability than CeraSeal sealer in all the respective groups (P < 0.05).

Conclusions:

AH Plus showed maximum wettability with 7% MA as the final irrigant, whereas, CeraSeal sealer showed the best wettability with 9% HEDP as the final irrigant.

Published: August 2023

Introduction:

To compare the effect of different intracanal medicaments on Enterococcus faecalis (E. faecalis) biofilm inside root canals using the viable count method (colony forming unit [CFU]/mL) and scanning electron microscope (SEM).

Materials and Methods:

A total of 180 mandibular premolars were selected. Access cavities, cleaning and shaping were done. After sterilization, all the teeth were inoculated by E. faecalis for 5 weeks to establish a mature biofilm. The inoculated roots were equally distributed into six experimental groups corresponding to the powder used: Calcium hydroxide Ca(OH)2; metronidazole (MDZ) and chitosan. Each powder was mixed with two different vehicles, 2%chlorhexidine (CHX) solution and sterile water, as an intracanal dressing for 2 weeks. Twenty infected root canals were representing the positive control group, and other 20 noninfected root canals represented the negative control group. To determine the bacterial load (CFU/mL), samples were collected by sterile paper points pre and postdressing. Using an SEM, the root canals from each group were topographically scanned. Kruskal–Wallis and Mann–Whitney U tests (post hoc test) were used to estimate and statistically analyze the bacterial reduction data (P < 0.05).

Results:

Mature biofilm formation was confirmed using SEM after incubation period. MDZ + CHX and Ca(OH)2 + CHX were significantly better than other intracanal medicaments (P < 0.05). The difference in antimicrobial effectiveness between other intracanal medications was not statistically significant.

Conclusion:

The combination of MDZ + CHX and Ca(OH)2 + CHX recorded a significant effect against E. faecalis biofilm among the intracanal medicament used.

Purpose Clinical prognostic criteria using preoperative factors were not developed for post–neoadjuvant therapy (NAT) surgery of pancreatic ductal adenocarcinoma (PDAC). We aimed to identify preoperative factors associated with overall survival (OS) in PDAC patients who underwent post-NAT curative-intent surgery and develop risk stratification criteria.Materials and Methods Consecutive PDAC patients who underwent post-NAT curative-intent surgeries between 2007 and 2020 were retrospectively analyzed. Demographic, laboratory, surgical, and histopathologic variables were collected. Baseline, preoperative, and interval changes of computed tomography (CT) findings proposed by the Society of Abdominal Radiology and the American Pancreatic Association were analyzed. Cox proportional hazard analysis was used to select preoperative variables associated with OS. We developed risk stratification criteria composed of the significant preoperative variables, i.e., post-NAT response criteria. We compared the discrimination performance of post-NAT response criteria with that of post-NAT pathological (yp) American Joint Cancer Committee TNM staging system.Results One hundred forty-five PDAC patients were included. Stable or increased tumor size on CT (hazard ratio [HR], 2.58; 95% confidence interval [CI], 1.58 to 4.21; p < 0.001) and elevated preoperative carbohydrate antigen 19-9 (CA19-9) level (HR, 1.98; 95% CI, 1.11 to 3.55; p=0.021) were independent factors of OS. The OS of the patient groups stratified by post-NAT response criteria which combined changes in tumor size and CA19-9 showed significant difference (p < 0.001). Such stratification was comparable to ypTNM staging in discrimination performance (difference of C-index, 0.068; 95% CI, –0.012 to 0.142).Conclusion “Any degree of decrease in tumor size on CT” and CA19-9 normalization or staying normal were independent favorable factors of OS. The combination of the two factors discriminated OS comparably to ypTNM staging.

Published: August 2023

We examine the effect of oil price uncertainty on sovereign credit risks in Gulf Cooperation Council (GCC) countries. Unlike past studies, we employ a structural vector autoregression with multivariate GARCH-in-mean (VAR-GARCH-in-mean) approach after filtering out outliers in the observed series. The findings show that uncertainty in the oil market has a positive impact on the sovereign Credit Default Swap (CDS) spreads of the GCC countries. Furthermore, we find that GCC sovereign CDS spreads react asymmetrically to positive and negative oil price shocks.

Water pollution, a recurring phenomenon in fishing waters of industrial cities in Nigeria, inadvertently constitute hazards to the host biotic communities and the ecosystem. To continuously delineate the impacts of pollution via sewage outlets on aquatic life, this rainy season study investigated Chrysichthys nigrodigitatus, an aquatic food from Ogun River and Epe Lagoon, Nigeria, both of which are locally channeled for sewage release. Sixty (60) samples of C. nigrodigitatus were collected from six sites each representing a group (n=10), with mean weight and length of 762.20 ± 11.05 g and 42.21 ± 0.30 cm respectively. Ajegunle (control), Alaapa and Quarry (test sites) along the Ogun River course in Abeokuta; Ebute-Alashe (control), Oluwo and Marina (test sites) along the Epe Lagoon. Analysis of Biochemical Oxygen Demand and Chemical Oxygen Demand showed elevated variations at the sampled test sites than the control sites and above WHO safe limits. Significant (p < 0.05) increases in concentrations of heavy metals (lead, arsenic and cadmium) in the fishing waters from the sampled test locations particularly the Quarry and Marina sites, as well as in blood samples of fish, were observed when compared with their respective controls. Antioxidants profiling showed significant increases (p < 0.05) in superoxide dismutase and catalase activities in fishes from Alaapa (14- and 3- folds), Quarry (8- and 4- folds), Oluwo (9- and 3- folds) and Marina (8- and 3- folds) sites, while significant increases in glutathione-S-transferase activity were observed only in fishes from Quarry (5- fold) and Marina (4- fold) sites respectively. The glutathione concentration significantly decreased in fishes from all the test sites while malondialdehyde concentrations significantly increased in fishes from all the test sites compared with the respective controls. Proximate analysis of the fish samples showed significant increases (p < 0.05) in moisture and fiber contents, but significant decrease in fat, ash and protein contents compared with the respective controls. The results of the study showed that sewage pollution of fishing waters is hazardous to aquatic life as it induces oxidative stress and significantly reduces the nutritional value of the fishes obtained from such water bodies.

Tubulavírus: evolução, taxonomia e interação com seu hospedeiro
Authors:   , Rezende Rafael Reis de
Published: August 2023

Os tubulavírus são vírus filamentosos que infectam procariotos sem causar lise celular. O processo de infecção por esses vírus, em muitos casos, induz modificações no perfil fenotípico do hospedeiro. Alguns tubulavírus que infectam bactérias fitopatogênicas dos gêneros Ralstonia e Xanthomonas geram modificações do perfil fenotípicos, em alguns casos aumento em outros redução da patogenicidade dessas bactérias. A biologia e a aplicação biotecnológica dos tubulavírus têm sido amplamente exploradas, mas estudos sobre a interação com hospedeiros e evolução deste grupo de vírus são escassos. As bactérias do complexo de espécies Ralstonia solanacearum (CERS) são habitantes naturais do solo capazes de infectar e matar plantas. Estas bactérias migram do solo para o xilema através das raízes da planta, onde desenvolvem um denso biofilme que interrompe o fluxo do xilema, causando a morte das plantas. Ralstonia solanacearum inovirus Brazil 1 (RSIBR1) é um tubulavírus que infecta a bactéria Ralstonia solanacearum isolado UB2014, o qual é incapaz de causar morte em plantas de tomates. Para determinar se há relação entre a ausência de patogenicidade da R. solanacearum e a infecção pelo RSIBR1, o isolado Ralstonia pseudosolanacearum GMI1000 agressivo foi infectado com o RSIBR1. Após a infecção o isolado R. pseusosolanacearum perdeu a capacidade de causar em morte de plantas de tomate, porém foi capaz de colonizar as plantas ao longo do tempo. Portanto, este trabalho teve como objetivo ampliar o entendimento da interação tubulavírus­Ralstonia, bem como estudar a evolução dos tubulavírus e propor um sistema para sua classificação taxonômica. Observamos que a evolução dos tubulavírus é principalmente impulsionada pelos hospedeiros e que a reconstrução filogenética a partir de genomas completos dos tubulavírus pode ser uma ferramenta adequada para a classificação desse grupo de vírus, que permite associar sua história evolutiva com suas características biológicas. Estudo de formação de biofilme in vitro mostrou que a infecção pelo RSIBR1 induz um aumento na produção de biofilme pela bactéria Ralstonia pseudosolanacearum; modula a produção de biofilme em diferentes condições como a disponibilidade ou ausência de glicose e nutrientes; induz a perda da motilidade do tipo swimming, e reduz da motilidade do tipo twitching. Além disso, a infecção pelo RSIBR1 altera a estrutura do biofilme da bactéria R. pseudosolanacearum com estrutura semelhante a tapete para um biofilme com estruturas com estruturas esféricas. Além disso, a infecção por RSIBR1 leva a uma redução na produção das vesículas externas, afeta a quantidade de DNA e proteínas nestas vesículas. For fim, também detectamos que o RSIBR1 expressa dois RNAs pequenos. Em conjuntos, esses fatores podem estar envolvidos na conversão fenotípica das bactérias do CERS. Palavras­-chave: Tubulavírus.

Published: August 2023

A corrosão é um processo físico-químico capaz de alterar as propriedades do material exposto a condições corrosivas. O setor de exploração de petróleo é um dos principais setores da economia que sofre com esse processo devido à deterioração de equipamentos, como tanques e oleodutos, que podem acarretar em vazamento de óleo. As bactérias redutoras de sulfato (BRS) constituem o principal grupo relacionado à corrosão microbiologicamente induzida (CMI), gerando prejuízos anuais à indústria do petróleo devido à formação de biofilme e a produção de sulfeto de hidrogênio (H₂S), um gás tóxico e corrosivo. Neste trabalho, um sistema de tanques piloto foi utilizado para simular o armazenamento de fluidos industrial, e inseridos cupons de aço carbono AISI 1020 para formação de biofilme. Nesse sistema, foi avaliado o efeito de um coquetel de bacteriófagos inespecíficos (10^7 UFP/mL), isolados de amostra de água residuais, sobre o biofilme e produção de H₂S de duas culturas mistas de BRS, denominadas AI e AP. Além do coquetel fágico, foi aplicado à cultura AP o biocida comercial sulfato de tetrakis(hidroximetil)fosfônico (THPS), de modo a reproduzir nos tanques o método de rotina empregado na indústria para inibir a biocorrosão. Em células planctônicas, a eficiência dos fagos foi avaliada pela quantificação de H₂S, leitura de DO600nm, contagem do número mais provável de células (NMP) e concentração de ATP total. Para as células do biofilme, foi avaliada a quantificação por NMP de células aderidas, concentração de ATP, perda da massa e taxa de corrosão ocorridas nos cupons, além do efeito sobre a estrutura do biofilme, o que foi verificado por Microscopia Eletrônica de Varredura (MEV) e pela da rugosidade da superfície obtida por perfilometria óptica. De maneira similar, com exceção à MEV, as mesmas análises foram conduzidas quando THPS estava sob estudo. Os resultados iniciais demonstraram redução de 77,8% na produção de H₂S pela cultura mista AI na presença do coquetel fágico, além de menor perda de massa e taxa de corrosão dos cupons avaliados. A população da cultura mista AP teve o crescimento interrompido pelo biocida, mas com surgimento de células resistentes após 12 dias. Com o coquetel fágico, a cultura mista AP apresentou redução de 26,1% na produção de H₂S, redução da matriz do biofilme formado e menor extensão dos vales desencadeados por pites de corrosão. Os dados obtidos sugerem o potencial biotecnológico do coquetel de bacteriófagos em um sistema piloto, além de propor alterações futuras como concentração, tempo de aplicação e composição do coquetel de modo a abranger os eventuais problemas de biocorrosão.

Published: August 2023

Okul müdürlerinin yaratıcı, etkili iletişim kuran, yeniliklere, değişime ve farklılıklara açık olmaları istenir. Bu özelliklere sahip müdürler, yaratıcı liderler olarak nitelendirilmektedirler. Bu çalışmada okul müdürlerinin yaratıcı liderlik özellikleri bazı değişkenler bakımından ele alınarak incelenmiştir. Araştırma nicel olup araştırma verilerinin toplanmasında Okul Müdürlerinin Yaratıcı Liderlik Özellikleri Ölçeği kullanılmıştır. Araştırmanın kişisel bilgi formunda öğretmenlerin cinsiyet, alan (branş), kıdem ve okul türü değişkenlerine yer verilmiştir. Araştırma evreni 2021-2022 öğretim yılında, Sinop ili Merkez ilçede görevli 906 öğretmen oluşturmaktadır. Bu öğretmenlerden basit tesadüfi örnekleme yoluyla 309 öğretmen örneklem olarak seçilmişlerdir. Araştırmanın bulgularına göre, öğretmenler okul müdürlerini çoğunlukla yaratıcı lider olarak algılamaktadırlar. Öğretmenlerin görüşleri cinsiyet ve kıdem değişkenlerine göre farklılık göstermezken branş ve okul türü değişkenlerine göre farklılık göstermektedir. Sınıf öğretmenleri, okul müdürlerini daha çok yaratıcı lider olarak görmektedirler. Ortaokul kademesinde görev yapan öğretmenlerin ise okul müdürlerinin yaratıcı liderlik özelliklerine ilişkin puanları düşük bulunmuştur. Yaratıcı liderlerin okul müdürü olarak atanmasına özen gösterilmesi önerilmektedir.
Incorporation of Criminological Theories in the Cameroonian Criminal Justice System
Authors: Ebolloh Emmanuel , Sama-Lang Irene , Ojong Thomas
Published: August 2023

Purpose: The study examined the incorporation of criminological theories notably the Classical school, Neo- Classical School, Positive school as well as the Anomie School of thought in the Cameroon Criminal justice system.

Methodology: Criminological theories focus in explaining the causes of crime identify the risk factors for committing crime and explaining how and why certain laws are created and implemented. The methodology adopted for purposes of this article is qualitative which is concerned with qualitative phenomenon and the chosen methods are doctrinal and empirical which involves a content analysis of existing literature, case law and observations.

Findings: The study discovered that the perception of criminological theories as articulated in the Cameroon Criminal Procedure Code, Cameroon Penal Code and other pieces of legislations have not been fully understood and implemented and this constitutes a major problem. This article concludes that the major protagonists who animated debate during the seventeen and eighteen centuries wanted a total overhaul of the criminal justice system in order to improve the welfare of the society and so were inspired with humanitarianism that gave them the urge to question the arbitrariness, cruelty, goriness and inefficiency of the criminal justice system and prison across the globe.

Unique Contribution to Theory, Practice and Policy: The study recommended that understanding why a person commits a crime and why individuals behave in certain ways, would help policy makers to develop a better and efficient ways of fully incorporating these criminological theories in the Cameroon Criminal justice system that will shape the ways to control crime and rehabilitate the criminal.

The Analysis of Liquefaction Potential and Post-Liquefaction Deformations at a Highway Bridge Crossing
Authors: Erarslan Nazife , Şen Büşra
Published: August 2023

The primary goal of this study is to geotechnically analyze the soil strength and liquefaction potential of the soil where the Seyrek highway junction and the bridge are built under earthquake-related dynamic stress. The analyses include comparisons of liquefaction potential using various empirical approaches, studies of post-liquefaction vertical deformation, and investigations into the influence of fill soil on liquefaction-induced surface deformation. Since the analyses of liquefaction potential in soils are made based on the "Simplified Method" approach, this method was also used in this study. This study also used the "Simplified Method" approach, which is the basis for studies of soil liquefaction potential. Four standard penetration tests (SPT) on the bridge piers were used to collect field data, and experiments in the lab were used to establish the requisite soil parameters. When the results of the Simplified Method analysis were performed according to the soil properties of the SK-1, SK-2, SK-3, and SK-4 drillings and the liquefaction analysis results were determined according to the required safety factor (Fs), liquefaction potential up to 18.5 meters was determined in all four SPT locations. Moreover, the results of surface damage effect analyses of the non-liquefied cover/fill layer on the Seyrek crossing bridge soil for all four SPP fields were found to be "visible" and the liquefiable layer thickness (H2) was found to be 10.5 m. The calculated liquefaction severity index (LS) value was found to be up to 52, which means the liquefaction effect was found to be "Possible liquefaction damage".

HUMAN RIGHTS AND CORPORATE SOCIAL RESPONSIBILITY AS IMPERATIVES FOR ABATING OIL SPILLAGES
Authors: Eda O. Eda , Awhefeada U. V. Awhefeada
Published: August 2023

The Niger Delta region is one of the major areas where the problem of oil spillage is prevalent. Over the years, several enactments have been promulgated with a view to abating the problem. Despite the existence of these enactments, the problem of oil spillage persists. The effect of oil spillage which ranges from environmental, health, economic and other negative developmental effects severely impinge on the enjoyment of human rights, particularly the right to life. Using the doctrinal method of research, this study makes use of both primary and secondary sources to analyse the nature and scope of human rights and the concept of corporate social responsibility (CSR) with a view to proffering a solution to the problem of oil spillage in the Niger Delta region. This study calls for a liberal interpretation of the relevant human rights provisions in the constitution and treaties as well as the adoption and enforcement of the principles of CSR as a way of abating the incidences of oil spillage in the Niger Delta region. This paper further advocates the imposition of stiffer penalties on erring Multinational Oil Companies whose activities negatively impact on the environment. This paper makes a case for the adoption of a corporate environmental system beyond the provision of basic amenities to oil producing host communities.
CHALLENGES OF NIGERIA’S DIGITAL ECONOMY: WAY FORWARD
Authors: Oluwasemilore I. A. Oluwasemilore
Published: August 2023

The digital economy is becoming a more important part of the global economy. The digital economy is worth $11.5 trillion globally, comparable to 15.5 percent of global Gross Domestic Product (GDP), and has risen two and a half times faster than global GDP over the past 15 years. The importance of the digital economy to a nation’s GDP cannot be exaggerated. For all its potential, the digital economy is yet a rough diamond.  The paper argues that the government must act as a regulator in order for the country to fully profit from the digital potential available. To be an effective regulator, the government must endeavour to remain ahead of the curve, comprehend the nuances of this type of business, and recognise that the digital economy cannot be governed in the same way as a traditional industry. The government's involvement as a regulator may extend to areas such as intellectual property, taxation, data security, and cyber security. The study applied a conceptual, descriptive and analytical approach, relying on extant literature on the benefits and challenges in the digital economy, focusing on the participation of government to maximize the sectors’ potential. Data were collected from statutes and case laws, relevant books, journal articles, materials from periodicals in these fields and materials from the internet, all data obtained was subjected to content analysis.
REKLAMCILIKTA VE PAZARLAMADA YENİ AKTÖR: SOSYAL ROBOTLAR
Authors: Erbaş Sefa
Published: August 2023

İnsanın doğa ve diğer her şey üzerindeki merkezi konumundan kaynaklı egoist düşüncesi, dünyaya hiç bu kadar zarar vermemişti. Antroposen olarak adlandırılan bu çağ, insanın tüketimle var oluşunu ifade etmesi ve bunun için her yolu mübah görmesi olarak nitelendirilir. Hümanist anlayışa dayalı bu sorunlu benmerkezcilik; insanın, diğer canlıların ve insan dışının (nesne) bir arada performatif ilişkisine dayalı posthümanizm düşünce zemininde tartışılmaya başlanmıştır. Bu anlayışın somut yansımalarından biri; yapay zeka teknolojisindeki gelişmelere dayalı, sosyal robotların insanla kurduğu etkileşimin, sıvılaşmış bir teknolojik deneyime yol açmasıdır: Robotları çelikten ibaret, toplumsal güç ilişkilerinde egemen bir fail olarak görmek yerine, kapasitelerine göre ağa dahil olan insan, insan olmayan arasındaki heterojen ve akışkan ilişkideki, eyleyen konumu üzerinden düşünebiliriz. Benzer şekilde, Bruno Latour’un Aktör-Ağ Teorisi; teknolojiyi bir töz olarak değil, süreç olarak yorumlar. Sosyal robotların; taklit, jest-doğal dil iletişimi gibi özellikleri sayesinde duygu ve etkileşim temelli asistan, refakatçi veya evcil hayvan olarak gündelik hayatta daha fazla görünür olması, insanın sonunu hazırlayacak distopik bir kurguya alternatif olarak gösterilebilir. Çalışmada, insan-makine arasındaki etkileşimi, teknolojik/sosyal belirlenimci bir perspektiften ziyade, bir ağa dahil olan eyleyenler üzerinden düşünmenin imkanına değindim. Ayrıca, Aktör-Ağ yaklaşımından hareketle, pazarlamada ve reklam sektöründe sosyal robot kullanımının tüketici deneyimlerini nasıl etkilediğine yönelik bazı araştırma sonuçlarını değerlendirdim.
