Point completion by a Stack‐Style Folding Network with multi‐scaled graphical features
Authors: Rao Yunbo , Xu Ping , Zeng Shaoning , Gou Jianping
Published: August 2023

Point cloud completion is prevalent due to the insufficient results from current point cloud acquisition equipments, where a large number of point data failed to represent a relatively complete shape. Existing point cloud completion algorithms, mostly encoder‐decoder structures with grids transform (also presented as folding operation), can hardly obtain a persuasive representation of input clouds due to the issue that their bottleneck‐shape result cannot tell a precise relationship between the global and local structures. For this reason, this article proposes a novel point cloud completion model based on a Stack‐Style Folding Network (SSFN). Firstly, to enhance the deep latent feature extraction, SSFN enhances the exploitation of shape feature extractor by integrating both low‐level point feature and high‐level graphical feature. Next, a precise presentation is obtained from a high dimensional semantic space to improve the reconstruction ability. Finally, a refining module is designed to make a more evenly distributed result. Experimental results shows that our SSFN produces the most promising results of multiple representative metrics with a smaller scale parameters than current models.

Authors: Sheba Mohamed A. , Mansour Diaa‐Eldin A. , Abbasy Nabil H.
Published: August 2023

Internet of Things (IoT) has recently become one of the fast‐growing technologies in the world. Integrating existing systems with smart grids still represents a significant challenge arising from the massive cost of upgrading the infrastructure. This paper provides an IoT infrastructure solution based on a newly designed low‐cost microcontroller‐based IoT remote terminal unit (RTU) to integrate new, old, and conventional sites of existing grids with smart grids. The IoT RTU supports Wi‐Fi communication and includes digital/analog inputs and outputs besides the advantage of serial data transmission standard RS‐485 as an industrial field communication (IFC). The Modbus communication protocol is utilized as a serial industrial protocol that can be interfaced over the RS‐485 standard. The advantage of having an IFC protocol integrated into the IoT infrastructure enables to link any supported device and publish the required data to the cloud, besides the ability to add smart metering technologies, which allows Advanced Metering Infrastructure (AMI) in these areas. IoT‐enabled Supervisory Control and Data Acquisition (SCADA) system is integrated with the proposed IoT infrastructure for its advantages of remote monitoring and control. The proposed IoT infrastructure is characterized by proper data security and low power consumption. The IoT infrastructure is simulated with an existing real application for proof of concept, and the results are discussed for different case studies.

Published: August 2023

Climatic hazards are becoming increasingly worrying in Morocco and elsewhere, leading to serious socio-economic and especially environmental effects, such as the drought that has become severe in Morocco, water stress, and climate change. Throughout our reserach work, we aim :to evaluate the degree of impact of CSR strategy adoption in protecting the environment, in Moroccan companies. Moreover, we have the goals of raising awareness among workers and owners of Moroccan companies about our subject, and also discovering the main points and recommendations to develop the current situation of CSR adoption in Morocco, in order to protect our environment. Accordingly, we conducted a 17-question survey to study the impact of CSR adoption by Moroccan companies on environmental protection. However, we have identified a number of dysfunctions to which we have proposed participative solutions, mobilizing our entire population’s opinions and suggestions. Consequently, we synthetise the growing interest of CSR strategy adoption by companies. However there is a number of challenges that these companies have to face if they are to increase the contribution of their CSR strategy effectively to the environmental protection, such as raising awareness of the importance of CSR adoption in environment protection.

The economic dynamic in Morocco’s Saharan coastal cities is focused on sea fishing. Nevertheless, while this activity plays an important role in the development of these areas, it also exposes them to the risks of overexploitation of fisheries resources and pollution, which are exacerbated by the effects of climate change. The aim of the present work is to analyze the correlation between the economic dynamics of Saharan coastal cities and the sustainability of fisheries resources. To realize this objective, we carried out an empirical study using a mixed quantitative and qualitative approach in Boujdour city from southern Morocco. The results showed that citizen participation and commitment are low. Also, the essential assets to face the challenges of sustainability and to support the introduction of mechanisms for accountable governance, integrated, and concerted management of fisheries resources, to pool the opportunities for innovation in green energy available in the region and to improve the efficiency of fishing activities, the promotion of integrative and inclusive territorial development and the protection of the environment.
Innovation as a lever for business resilience in times of crisis: The case of Morocco’s energy sector
Authors: Cheggag Meryem , Mokhlis Chams-Eddoha
Published: August 2023

Today’s businesses are increasingly confronted with uncertainty, unpredictability and environmental complexity, as well as severe, recurrent and consecutive crises. In this context, innovation and resilience are the watchwords. Resilience refers to a company’s ability to adapt and recover from shocks and disruptions. Innovation, on the other hand, is the process by which new ideas, products, services or methods are developed, implemented and adopted. Despite the abundance of research on organizational resilience and innovation, very few have addressed the relationship between these two concepts, let alone in the Moroccan context. The objective of this article is to analyze the relationship between these two key concepts and to explore how innovation can be a lever for organizational resilience in times of crisis. To do this, we conducted a qualitative study, through semi-structured interviews with Moroccan companies operating in the energy sector. The main results confirm the existence of a positive correlation between the two concepts. However, innovation alone does not guarantee the exit from the crisis and the resilience of companies. In order to validate and generalize the results obtained, we recommend conducting a confirmatory quantitative study.

Authors: Ouakka Sara , El Alaoui Aicha
Published: August 2023

Inclusive education is considered as an education system for people with disabilities in order to integrate them with the rest of the students and guarantee their right to education without discrimination. However, there are problems raised at the beginning of the implementation of this new system. And given the importance of the subject, many researchers from different countries of the world have discussed this inclusive system in order to find solutions that facilitate the process of learning these people and their integration into normal life. This article tries to address the issue of inclusive education and its constraints in the province of El-Jaddida in Morocco. We adopted a qualitative study to clarify and understand this system, based on cases of dyslexic children requiring the presence of the school life assistant and additional time for the adaptation of certification exams. And therefore the improvement of this system requires the training and supervision of qualified teachers with skills in the field, while ensuring an appropriate and child-friendly environment in coordination with the health sector.

Published: August 2023

Perinatal asphyxia (PA) is a major health problem, responsible for high mortality and a wide range of morbidity. Several factors play a part in the occurrence of perinatal mortality during asphyxia. The aim of this work was to identify factors predictive of perinatal mortality following PA, using an unmatched case-control study. Thus, 31 cases and 126 controls were identified with a total of 157 newborns suffering from PA. It was carried out during April 1 to June 30, 2022, at the Mohammed VI University Hospital in Marrakech. The socio-demographic, clinical, and biological data of the newborns were collected using an evaluation grid. In this series, the sex ratio was 0.96 and the case-fatality rate 20%. The results showed that the factors showing a statistically significant association in the genesis of mortality in PA cases were : intrauterine growth retardation [(ORA= 4711,799), 95%, IC : ( 48,964, 453416,766)] ; maternal history [ (ORA =31,876, 95%,CI : (1,346;755,149)] ; Apgar index after 5 min less than or equal to 3: [(ORA=139,75), 95%, CI : (16,523 ; 1182,01)]; and congenital malformations : [(ORA=241,435), 95%, CI : ( 6,044 ; 9644,748)]. Consequently, addressing these factors is crucial to identify high-risk newborns at an early stage and to implement appropriate measures. The goal is to eliminate avoidable morbidity and disability.

Published: August 2023

With the establishment of the national strategy for financial inclusion in 2015, Morocco launched a challenge to the promote access and use of basic financial products and services such as opening a bank account, savings and insurance while dealing with the various factors and obstacles contributing to financial exclusion. The objective of this paper is to explain the factors of financial exclusion in Morocco and their impact on the environment. To achieve this objective, we have adopted a method based on the application of grounded theory while making a study that is both qualitative and quantitative through a questionnaire and semi-structured interviews conducted on the Moroccan population aged 18 years and above for a period of two months (April and May 2023) using data processing software such as SPSS and N’vivo. The results show that there are several factors that lead to financial exclusion, mainly : lack of trust in financial institutions, low level of education and financial knowledge, lack of financial products and services adapted to the needs of individuals and companies such as loans granted to finance environmental protection projects. To reduce and curb these obstacles, it is recommended to develop financial education programs, and to strengthen the transparency and accountability of financial intuitions.

Published: August 2023

Understanding data and extracting information from it are the main objectives of data science, especially when it comes to big data. To achieve these goals, it is necessary to collect and process massive data sets, arriving at the system in different formats at great velocity. The Big Data era has brought us new challenges in data storage and management, and existing state-ofthe-art data storage and processing tools are poised to meet the challenges while posing challenges to the next generation of data. Big Data storage optimization is essential for improving the overall efficiency of Big Data systems by maximizing the use of storage resources. It also reduces the energy consumption of Big Data systems, resulting in financial savings, environmental protection, and improved system performance. Hadoop provides a solution for storing and analysing large quantities of data. However, Hadoop can encounter storage management problems due to its distributed nature and the management of large volumes of data. In order to meet future challenges, the system needs to intelligently manage its storage system. The use of a multi-agent system presents a promising approach for efficiently managing hot and cold data in HDFS. These systems offer a flexible, distributed solution for solving complex problems. This work proposes an approach based on a multi-agent system capable of gathering information on data access activity in the HDFS cluster. Using this information, it classifies data according to its temperature (hot or cold) and makes decisions about data replication based on its classification. In addition, it compresses unused data to manage resources efficiently and reduce storage space usage.

Les représentations sociales de la sexualité après le cancer : une perspective sociologique intégrant les sciences de la vie et de la terre
Authors: El Ghali Maryama , Borj Fouzia
Published: August 2023

Le cancer et la sexualité sont des sujets complexes et interconnectés qui suscitent différentes perceptions dans notre société, ce qui affecte la manière dont nous abordons ces questions. Les personnes atteintes de cancer rencontrent souvent des défis qui retentissent sur leur vie sexuelle en raison des effets indésirables de la maladie et des traitements. De plus, les changements identitaires, l’image corporelle altérée et les tabous entourant la sexualité, augmentent ces difficultés. Tout cela peut contribuer à une vision négative de la sexualité chez les patients atteints de cancer. Il est crucial de comprendre et de reconnaître ces différentes perceptions sociales afin de fournir un soutien approprié aux personnes touchées. Une approche mixte, combinant les récits de vie et les questionnaires portant spécifiquement sur l’aspect sexuel, est essentielle pour mieux saisir les expériences des personnes atteintes de cancer. Les stéréotypes, les préjugés et les normes sociales peuvent contribuer à la stigmatisation de ces patients et renforcer les tabous, ce qui limite les discussions ouvertes sur la sexualité pendant et après le cancer, et entrave la possibilité de mener une vie épanouissante similaire à celle d’avant la maladie. Afin d’approfondir notre appréhension de la relation entre la sexualité et le cancer, il est essentiel d’adopter une approche qui intègre différentes disciplines et encourage la collaboration entre les spécialités des sciences sociales, des sciences de la vie et des sciences de la terre. Une démarche sociologique nous permettra d’explorer de manière approfondie ces questions complexes en considérant tous les aspects pertinents.

Published: August 2023

Dans un environnement concurrentiel, les entreprises se retrouvent dans l’obligation de renforcer leur compétitivité. Opter pour des opérations de fusion peut souvent être un moyen pour y arriver. Cependant l’échec d’un bon nombre de fusions d’entreprises a attiré l’attention des chercheurs en vue d’en connaitre les causes. Ceux-ci s’orientent de plus en plus vers le facteur humain comme élément déterminant de la réussite de ces opérations, et plus précisément, bien que ces recherches restent peu nombreuses, vers l’importance de la conduite de changement lors de ces opérations, toujours sollicitées par les entreprises. L’objectif de cet article est de déceler le rôle de la conduite de changement organisationnel dans la réussite des fusions, en prenant comme cas des entreprises opérant dans le secteur énergétique. Nous avons adopté une posture interprétativiste basée sur une approche qualitative inductive, à travers des entretiens semi directifs. L’analyse de contenu permet de constater que le changement organisationnel occasionné est accompagné de résistance et de difficulté d’intégration. Plusieurs facteurs favorisant la conduite de changement sont mis en avant dans cette étude, qui pourrait être enrichie davantage en analysant le changement dans d’autres contextes. Nous signalons que nous avons envisagé de réaliser cet article en d’autres langues.

Published: August 2023

Anaplastic large cell lymphoma (ALCL) is the second most common type of peripheral T cell lymphoma and an aggressive mature T cell lymphoma. About 50 to 70% of systemic ALCLs are anaplastic lymphoma kinase positive (ALK +), the proportion even higher in the pediatric population. The 5-year survival after chemotherapy is around 70 to 80%. But there is a subgroup of ALK+ ALCL patients who are refractory to chemotherapy. Brentuximab vedotin is an approved agent for such patients. The activity of ALK inhibitors in ALK+ non-small cell lung cancer is well known and has been approved for use. The efficacy and safety of ALK inhibitors in ALK + ALCL are largely under-reported. Here we have reported our experience in the use of ALK inhibitors in relapsed refractory ALK+ ALCL.

Authors: Pollock Jordan R. , Mujahed Tala , Smith Jacob F. , Arthur Jaymeson R. , Brinkman Joseph C. , Atkinson Christina M. , Pollock Nathan T. , Renfree Kevin J.
Published: August 2023

Background Patients often turn to online reviews as a source of information to inform their decisions regarding care. Existing literature has analyzed factors associated with positive online patient ratings among hand and wrist surgeons. However, there is limited in-depth analysis of factors associated with low patient satisfaction for hand and wrist surgeons. The focus of this study is to examine and characterize extremely negative reviews of hand and wrist surgeons on Yelp.com.

Methods A search was performed using the keywords “hand surgery” on Yelp.com for eight major metropolitan areas including Washington DC, Dallas, New York, Phoenix, Los Angeles, San Francisco, Boston, and Seattle. Only single-star reviews (out of a possible 5 stars) of hand and wrist surgeons were included. The complaints in the 1-star reviews were then categorized into clinical and nonclinical categories.

Result A total of 233 single-star reviews were included for analysis, which resulted in 468 total complaints. Of these complaints, 81 (18.8%) were clinically related and 351 (81.3%) were nonclinical in nature. The most common clinical complaints were for complication (24 complaints, 6%), misdiagnosis (16 complaints, 4%), unclear treatment plan (16 complaints, 4%), and uncontrolled pain (15 complaints, 3%). The most common nonclinical complaints were for physician bedside manner (93 complaints, 22%), financially related (80 complaints, 19%), unprofessional nonclinical staff (61 complaints, 14%), and wait time (46 complaints, 11%). The difference in the number of complaints for surgical and nonsurgical patients was statistically significant (p < 0.05) for complication and uncontrolled pain.

Clinical Relevance Patient satisfaction is dependent on a multitude of clinical and nonclinical factors. An awareness of online physician ratings is essential for hand and wrist surgeons to maintain and improve patient care and patient satisfaction. We believe the results of our study could be used to further improve the quality of care provided by hand and wrist surgeons.
Myocardial Fibrosis and Left Bundle Branch Block Complicating an Athlete's Heart Syndrome Treated Homeopathically: A Case Report
Authors: Jeggels Herman John Daniel
Published: August 2023

Background During 2013, a 59-year-old male patient, a medical practitioner and lifelong sportsperson, complained of being constantly conscious of his heart action, and left sternal heave, as well as retrosternal heaviness at rest. On October 23, 2013, an electrocardiogram (ECG) showed some signs of an athlete's heart syndrome. An ECG on 11 January, 2019, shockingly showed a complete left bundle branch block (LBBB), a broad complex QRS sinus rhythm ECG, without ever experiencing angina pectoris after doing four sets of 20 push-ups.

Methods A complication of an athlete's heart may be myocardial fibrosis (MF). MF is the primary pathology to treat, as well as its comorbidities synergistically, when they obstruct progress. Thus, Calcarea fluorata (Calc-f) was prescribed for endocardial fibrosis, Iberis amara (Iber) for endomyocardial fibrosis, Cactus grandiflorus (Cact) for pulmonary arterial hypertension and right ventricular strain, and Crataegus laevigata (Crat) for subendocardial ischaemia.

Results After 17 months on Calc-f, the LBBB was unchanged. Iber was again prescribed on February 13, 2022. On February 23, 2022, after 10 days on Iber, a narrow complex QRS sinus rhythm (SR) ECG was recorded with a QRS of 90 milliseconds. This was the first SR ECG after having had a permanent complete LBBB for at least 3 years.

Conclusions This case report documents via ECGs the biological effectiveness of Calc-f and Iber for MF. SR returned after the employment of, respectively, Iber and Cact. After employing Crat, the abnormal inverted T waves in most leads became positive. Since October 16, 2022 and beyond, there is a stable SR, but any intense exertion causes an LBBB.

Materials and Methods A total of 362 general dentists were included in this cross-sectional study. The participants were asked to complete a self-administered online questionnaire of dentist characteristics and perceived barriers in multiple domains (children, parents, dentists, and healthcare system-related barriers). The frequency of responses to items of the questionnaire was presented. The Mann–Whitney U test was used to compare perceived barriers by gender, Kruskal–Wallis by practice sector, and Spearman analysis was used to assess the correlation between perceived barrier with age, years of practice experience, weekly practice hours, percentage of pediatric patients, percentage of pediatric preventive care, and percentage of insured patients. A multivariate analysis was conducted through structural equation modeling.

Results The highest perceived barrier was found to be healthcare system-related, followed by parents, children, and dentists themselves. Most participants thought parents have poor knowledge of pediatric caries prevention (n = 290; 80%), and dental care for young children emphasizes curative treatment over prevention (n = 257; 70%). The multivariate analysis showed that dentists' practice sector and age affect perceived barriers and pediatric preventive care the most.

Conclusion Factors and barriers identified in this study must be the main focus of oral health programs, and dentists, as service providers, need proper training to address these barriers to optimize caries prevention in Indonesia.

Objective Periodontal disease is one of the most common infectious diseases. Several factors are associated with increased susceptibility of periodontal disease such as hormonal changes during pregnancy. Although pregnancy does not directly cause gingivitis, it can aggravate preexisting periodontal disease. This study aimed to evaluate knowledge of the association between periodontal disease and pregnancy in pregnant females.

Materials and Methods A convenience sample of pregnant females attending two United Arab Emirates government hospitals was recruited for this study. A 23-item questionnaire was developed with four sections, covering sociodemographic details, oral hygiene, oral symptoms during pregnancy, and knowledge of periodontal health during pregnancy. The study was conducted between April and October 2017. All participants consented to the survey.

Results A total of 100 participants with a mean age of 31 years (± 5.9) completed the survey. Most respondents brushed their teeth 2 to 3 times a day (65%), used a manual toothbrush (93%) but only visited the dentist when in pain (62%). Few respondents self-reported any gingival signs and symptoms during pregnancy; 38% had bleeding gums, 27% had no gum swelling, and 34% had bad odor/taste/smell. Only 21% of pregnant females lost a tooth/teeth during pregnancy, 15% believed that pregnancy increased the likelihood of gum disease, and 66% of gynecologists did not advise a visit to the dentist.

Housewives were significantly less knowledgeable about periodontal health than students/employed respondents (p = 0.01). Quality of knowledge was not associated with educational attainment (< 0.06). Respondents > 30 years of age were more likely to believe in “a tooth for a baby” than younger participants aged < 30 years (p < 0.05). A logistic regression model showed that educational attainment was not a predictor for the belief in “a tooth for a baby” but age was a significant predictor (odds ratio = 2.0).

Conclusion Protocols should be developed in antenatal clinics in order to improve periodontal health in pregnant females and to prevent complications that can result in adverse pregnancy outcomes.

Dung from calves treated with synthetic pyrethroids negatively influenced, in varying degrees, survival, reproduction and size of the common dung fly Neomyia cornicina(Fabricius). This was documented in assays where the coprophagous larvae and adults of N. cornicina were exposed to dung collected from calves dosed with topical preparations of deltamethrin, flumethrin, cyfluthrin, and α-cypermethrin. Larval mortality was significantly increased in dung collected up to at least seven days after treatment with deltamethrin, α-cypermethrin and cyfluthrin. Alpha-cypermethrin caused significant mortality of adults allowed to feed on moist dung. Nulliparous flies fed for six days on dung collected three days after treatment of calves with α-cypermethrin or deltamethrin showed little or no ovarian development. A tendency for a comparable effect with flumethrin was also observed. A connection between ovarian development and inhibition of feeding was indicated by the observation of significantly lowered excretion rates in flies exposed to residues of deltamethrin, α-cypermethrin and flumethrin. Larvae that survived exposure to dung from calves dosed with deltamethrin, α-cypermethrin, or cyfluthrin gave rise to smaller flies. The effect on adult fly size decreased when larvae were exposed to dung collected at longer times after treatment of the calves. Adult fly size was significantly reduced in dung collected up to 14 days (α-cypermethrin) or up to 28 days after treatment (deltamethrin and cyfluthrin). Fluctuating asymmetry of a wing vein character did not reflect the anticipated levels of exposure. The study strongly indicated that the use of synthetic pyrethroids affected the insect dung fauna and that such use may reduce dung decomposition.

The Chinese citrus fruit fly, Bactrocera (Tetradacus) minax (Enderlein), is one of the major citrus pests in Bhutan and can cause >50% mandarin (Citrus reticulata Blanco) fruit drop. As part of the development of a management strategy for the fly in mandarin orchards, population monitoring and experimental manipulations were carried out to determine: (i) adult emergence period; (ii) adult phenology patterns; (iii) period of crop susceptibility; and (iv) period from fruit drop to pupation. In western Bhutan, adult flies emerge from the overwintering pupal stage in late April/early May. Most flies are mature by the end of May and it is inferred that mating occurs at this time: from the beginning of June males rapidly disappear from the population and by mid- to late June are rare or absent from traps. Mature females are present in the mandarin crop at the beginning of June, but very little oviposition occurs until mid-June, while most damage has occurred by mid-July. Initiation of oviposition into mandarins is almost certainly linked to crop phenology. Adult flies disappear from the orchard system during August. After fruit drop, larvae were recorded leaving the fruit to pupate within 13 days. The use of early to mid-season protein bait sprays and/or targeted use of systemic insecticides during the one month oviposition period, plus the removal of fallen fruit once every 10 days, are recommended as control strategies.
Geographic biotype and host-associated local adaptation in a polyphagous species, Lambdina fiscellaria (Lepidoptera: Geometridae) feeding on balsam fir on Anticosti Island, Canada

The debate about mechanisms underlying the evolution of host specialization by herbivorous insects remains open. Natural selection may act locally and lead to different patterns of geographic variation in life history traits of polyphagous herbivores. The hypothesis of genetically-based trade-offs in offspring performance on different hosts has been proposed but this has rarely been demonstrated. Under laboratory conditions, the biological performance of two populations of the hemlock looper Lambdina fiscellaria (Guenée), a highly polyphagous lepidopteran, was compared when reared on three different tree host species: balsam fir, eastern hemlock and sugar maple. One population originated from Anticosti Island, Québec, Canada, where the insect has evolved without having access to two of the three tree species tested, the other being from the mainland where all tree species are present. When reared on balsam fir foliage, which was naturally available to each population, larvae from Anticosti Island underwent four instars compared with five for the mainland population, indicating the existence of geographic biotypes in L. fiscellaria. When reared on the foliage of non-naturally available host trees, larvae from Anticosti Island had a higher incidence of supernumerary instars. This is a unique example where local adaptation to environmental conditions of an insect herbivore is expressed through a differential number of larval instars. Moreover, the Anticosti Island population showed a higher growth related index on the host available to both populations indicating that a fitness trade-off was the evolutionary process underlying the local adaptation of this population on balsam fir.
