A Function of Amyloid-β in Mediating Activity-Dependent Axon/Synapse Competition May Unify Its Roles in Brain Physiology and Pathology
Authors: Huang Zhen
Published: January 2023

Amyloid-β protein precursor (AβPP) gives rise to amyloid-β (Aβ), a peptide at the center of Alzheimer’s disease (AD). AβPP, however, is also an ancient molecule dating back in evolution to some of the earliest forms of metazoans. This suggests a possible ancestral function that may have been obscured by those that evolve later. Based on literature from the functions of Aβ/AβPP in nervous system development, plasticity, and disease, to those of anti-microbial peptides (AMPs) in bacterial competition as well as mechanisms of cell competition uncovered first by Drosophila genetics, I propose that Aβ/AβPP may be part of an ancient mechanism employed in cell competition, which is subsequently co-opted during evolution for the regulation of activity-dependent neural circuit development and plasticity. This hypothesis is supported by foremost the high similarities of Aβ to AMPs, both of which possess unique, opposite (i.e., trophic versus toxic) activities as monomers and oligomers. A large body of data further suggests that the different Aβ oligomeric isoforms may serve as the protective and punishment signals long predicted to mediate activity-dependent axonal/synaptic competition in the developing nervous system and that the imbalance in their opposite regulation of innate immune and glial cells in the brain may ultimately underpin AD pathogenesis. This hypothesis can not only explain the diverse roles observed of Aβ and AβPP family molecules, but also provide a conceptual framework that can unify current hypotheses on AD. Furthermore, it may explain major clinical observations not accounted for and identify approaches for overcoming shortfalls in AD animal modeling.

Authors: Faiza  , Khalil K.
Published: January 2023

This study envisages assessing the effects of the COVID-19 on the on-time performance of US-airlines industry in the disrupted situations. The deep learning techniques used are neural network regression, decision forest regression, boosted decision tree regression and multi class logistic regression. The best technique is identified. In the perspective data analytics, it is suggested what the airlines should do for the on-time performance in the disrupted situation. The performances of all the methods are satisfactory. The coefficient of determination for the neural network regression is 0.86 and for decision forest regression is 0.85, respectively. The coefficient of determination for the boosted decision tree is 0.870984. Thus boosted decision tree regression is better. Multi class logistic regression gives an overall accuracy and precision of 98.4%. Recalling/remembering performance is 99%. Thus multi class logistic regression is the best model for prediction of flight delays in the COVID-19. The confusion matrix for the multi class logistic regression shows that 87.2% flights actually not delayed are predicted not delayed. The flights actually not delayed but wrongly predicted delayed are12.7%. The strength of relation with departure delay, carrier delay, late aircraft delay, weather delay and NAS delay, are 94%, 53%, 35%, 21%, and 14%, respectively. There is a weak negative relation (almost unrelated) with the air time and arrival delay. Security delay and arrival delay are also almost unrelated with strength of 1% relationship. Based on these diagnostic analytics, it is recommended as perspective to take due care reducing departure delay, carrier delay, Late aircraft delay, weather delay and Nas delay, respectively, considerably with effect of 94%, 53%, 35%, 21%, and 14% in disrupted situations. The proposed models have MAE of 2% for Neural Network Regression, Decision Forest Regression, Boosted Decision Tree Regression, respectively, and, RMSE approximately, 11%, 12%, 11%, respectively.
Fuzzy AHP point factored inference system for detection of cardiovascular disease
Authors: Stephen M. , Felix A.
Published: January 2023

The World health organization (WHO) reported that cardiovascular disease is the leading cause of death worldwide, particularly in developing countries. But while diagnosing cardiovascular disease, medical practitioners might have differences of opinions and faced challenging when there is inadequate information and uncertainty of the problem. Therefore, to resolve ambiguity and vagueness in diagnosing disease, a perfect decision-making model is required to assist medical practitioners in detecting the disease at an early stage. Thus, this study designs a fuzzy analytic hierarchy process (FAHP) point-factored inference system to detect cardiovascular disease. The attributes are selected and classified into sub-attributes and point factor scale using the clinical data, medical practitioners, and literature review. Fuzzy AHP is used in calculating the attribute weights, the strings are generated using the Mamdani fuzzy inference system, and the strength of each set of fuzzy rules is calculated by multiplying the attribute weights with the point factor scale. The string weights determine the output ranges of cardiovascular disease. Moreover, the results are validated using sensitivity analysis, and comparative analysis is performed with AHP techniques. The results show that the proposed method outperforms other methods, which are elucidated by the case study.

Linear feature projective geometric damped convolutional deep belief network for indoor floor planning
Authors: Pichaimani Venkateswari , Kalava Manjula Ramakrishama
Published: January 2023

Wireless localization or positioning is essential for delivering location-based services for designing location tracking systems. Traditional indoor floor planning system employs wireless signals for accurate position estimation. But these positioning schemes failed to perform position estimation effectively and accurately through many obstacles or objects. The novel technique called Linear Features Projective Geometric Damped Convolutional Deep Belief Network (LFPGDCDBN) is introduced to improve the position estimation accuracy with minimum error. The proposed LFPGDCDBN technique includes two major processes namely dimensionality reduction and position estimation. First, the dimensionality reduction process is performed by projecting the principle features using Linear Helmert–Wolf blocked Sammon projection. After the feature selection, Geometric Levenberg–Marquardt Convolutional deep belief network is employed to estimate the position of the devices with higher accuracy and minimum error. The Convolutional deep belief network uses the triangulation geometric method to identify the position of the device in an indoor positioning system. Then the Levenberg–Marquardt function is a Damped least square method to minimize the squares of the deviations between the expected and observed results at the output unit. As a result, the LFPGDCDBN increases the positioning accuracy and minimizes the error rate. Experimental MATLAB assessment is carried out with various factors such as computational time, Computational space, positioning accuracy, and positing error. The experimental results and discussion indicate that the proposed LFPGDCDBN provides improved performance in terms of achieving higher positioning accuracy and minimum error as well as computational time when compared to the existing methods. The experimental results and discussion indicate that the proposed LFPGDCDBN increases the positioning accuracy by 47% and computational time, computational complexity, and reduces the positioning error by 45%, 29%, and 74% as compared to state-of-the-art works.
The coverage of medical injuries in company trial informed consent forms
Authors: Healy David , Germán Roux Augusto , Dressen Brianne
Published: January 2023

Best practice consent forms in company clinical trials detail the financial coverage for medical treatment of injuries. In trials undertaken for licensing purposes these arrangements can raise concerns. We detail three cases in which elements of the consent forms appear misleading and designed to elicit a consent to participation that might not be forthcoming if volunteers for these clinical trials were aware that what is outlined in principle is not likely to happen in practice. Beyond clinical trial participants, these consent forms have wider implications. Medical coverage of injuries sustained in a clinical trial is a nexus where business, scientific and ethical considerations meet. It is not clear that anyone to date has grappled with the issues posed. This paper uses three clinical trials to illustrate the problems to be addressed.

Published: January 2023

BACKGROUND: Working with lifting and carrying heavy loads and kneeling postures with crawling, squats or heel seat position lead to progressive cartilage wear with premature degenerative changes. OBJECTIVE: To investigate the effects of the exercise based multimodal ‘knee college’ and its sustainability in patients with knee osteoarthritis with data assessments before and after a starter course, before a 1-year and a 2-year follow-up refresher course in a retrospective observational study. METHODS: A sample of 401 male patients (ICD10: M17 [arthrosis of knee]/ICF: s75011 [knee joint]) from the construction industries were assessed with Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), EuroQol (EQ-5D), Performance Assessment Capacity Testing (PACT), Isokinetic torque H/Q ratio and Physical Work Capacity Test (PWC). Retrospectively, after two years they were divided into three groups based on their intermediate sporting activity: gym (n = 194, age: 50.8±7.0, BMI: 28.8±4,3), home training (n = 110, age: 50.2±7.0, BMI: 28.4±4,2), no exercising (n = 97, age: 48.2±7.0, BMI: 29.2±4,6). RESULTS: Patients did not differ significantly in their demographic and anthropometric data prior to the rehab program. Significant interaction effects indicated group-dependent differing sustainability effects for the 2-year follow-up (all outcomes: p < 0.001, except for H/Q ratio: p = 0.03). Group-wise analyses revealed significant acute improvements (after 3-week in-patient starter rehab program: p < 0.05) for all groups in almost all outcomes (except the ‘no sport’ group, H/Q ratio p = 0.08). These effects remained significant (p < 0.001) only for the ‘gym’ group during the 1-year and 2-year follow-up. CONCLUSION: Our data indicate that 2-year sustainability of acute rehabilitation starter effects was demonstrated especially for patients with adherence and compliance to long-term gym based exercises.

Published: January 2023

BACKGROUND: The physical factors associated with musculoskeletal pain in nursing personnel have been largely investigated, although the role of sleep and psychological factors resulting in musculoskeletal pain has not been addressed thoroughly. OBJECTIVE: This study aimed to explore the prevalence of musculoskeletal pain and investigate how sleep and psychological factors influence musculoskeletal pain in a nursing group. METHODS: Nordic standard questionnaires were distributed to 230 female nurses. Chi-square tests were performed to assess the associations between sleep problems, psychological problems, and musculoskeletal pain symptoms. Binary logistic regression analysis was also conducted to identify the primary factors influencing the prevalence of musculoskeletal pain. RESULTS: The highest prevalence of pain was observed in the lower back, neck, and shoulders, whereas the lowest prevalence of pain was observed in the ankles, feet, elbows, and hips/buttocks. Chi-square analysis and binary logistic regression showed that sleep duration, sleep onset time, and sleep quality all significantly contributed to the development of neck and upper back pain. With regard to the psychological factors, only occupational pride and stress had a significant effect on pain; in contrast, family support did not show any significant influence. CONCLUSION: Compared with other body regions, musculoskeletal pain in the lower back, neck, and shoulders requires more attention and preventive interventions. Special efforts should be made to shift the workday system of the nursing group because of the strong correlation between sleep problems and pain. Incentives other than penalty mechanisms should be considered seriously in nursing to boost occupational pride and relieve job stress.

Published: January 2023

BACKGROUND: In Europe it is commonly accepted that psychosocial hazards may influence the mental health of employees. However, mental disorders such as depression are generally not acknowledged as an occupational disease covered by the workers compensation system. Studies indicate that workers compensation claim processes may affect employee’s health negatively due to a demanding case process. If filing a workers’ compensation claim can harm the employees’ health, it is highly relevant to pay attention to employees with mental health claims, as they are most likely vulnerable and face a very low chance of compensation. OBJECTIVE: This study investigates how employees with work-related mental disorders experience the process of seeking workers compensation from the Danish Workers’ Compensation System. METHOD: Interview (N = 13) and questionnaire (N = 436) data from claimants were analysed. RESULTS: Analysis showed that even though many employees wished for the claim to influence the conditions at the workplace, there seemed to be a lack of preventive health and safety initiatives in the workplaces. Central stakeholders such as health and safety representatives were often not involved. Management involvement was often experienced negatively, and the Danish Working Environment Authority rarely conducted workplace inspections. Employees experienced inadequate information about the workers’ compensation process and experienced a lack of coordination between stakeholders. CONCLUSION: A more supportive and coordinated approach in the Workers’ Compensation System is recommendable. The processes in the system could be evaluated using the Social Insurance Literacy concept, to ensure sufficient support of the claimants and reduce potential harmful aspects of the process.
Impact of experience on the sensitivity, acceptability, and intrusive of two subjective mental workload techniques: The NASA TLX and workload profile
Authors: Barajas-Bustillos Manuel A. , Maldonado-Macías Aidé Aracely , Serrano-Rosa Miguel Angel , Hernandez-Arellano Juan Luis , Llamas-Alonso Luis , Balderrama-Armendariz Omar
Published: January 2023

BACKGROUND: Today’s work environments have high cognitive demands, and mental workload is one of the main causes of work stress, human errors, and accidents. While several mental workload studies have compared the mental workload perceived by groups of experienced participants to that perceived by novice groups, no comparisons have been made between the same individuals performing the same tasks at different times. OBJECTIVE: This work aims to compare NASA Task Load Index (NASA-TLX) to Workload Profile (WP) in terms of their sensitivity. The comparison considers the impact of experience and task differentiation in the same individual once a degree of experience has been developed in the execution of the same tasks. It also considers the acceptability and intrusivity of the techniques. METHODS: The sample consisted of 30 participants who performed four tasks in two sessions. The first session was performed when participants had no experience; the second session was performed after a time of practice. Mental workload was assessed after each session. Statistical methods were used to compare the results. RESULTS: The NASA-TLX proved to be more sensitive to experience, while the WP showed greater sensitivity to task differentiation. In addition, while both techniques featured a similar degree of intrusivity, the NASA-TLX received greater acceptability. CONCLUSION: The acceptability of WP is low due to the high complexity of its dimensions and clarifying explanations of these may be necessary to increase acceptability. Future research proposals should be expanded to consider mental workload when designing work environments in current manufacturing environments.

Published: January 2023

Perishable products are a kind of agricultural product that has a very short shelf-life, such as fruits and vegetables. To maintain the quality, as expected by consumers, it needs a system that could be utilized to manage production planning of those perishable products. By utilizing this system should also minimize human error hence reducing the loss. To increase the availability of fruits and vegetables for people who live in cities is by shortening the distance between supplier (farmer) and consumer (citizen). Urban Farming is one way to increase the availability of fruits and vegetables for people who live in city. To create an efective Urban Farming infrastructure, it need a system by utilizing information technology to manage its supply chain. All members of the supply chain network including producers (farmers), distribution center, administrator, retailers, and consumer can access this system. Members of the supply chains can manage every information related to him/her, and able to see the information of the other members when needed. With the integrated information, the planting schedule planning process, the selection of products that will be planted, harvest schedules, and reports related to the fulfillment of the request can be done easily and faster

Published: January 2023

—The Batik of Pekalongan is a heritage that continues to be maintained and until now it is still used as a source of livelihood for the majority of the people in Pekalongan city, so the city of Pekalongan is known as the city of batik. However, the existence of batik is facing a serious threat, caused by the abundance of textile products with batik motifs (batik printing) on the market, but not matched by increased public knowledge of batik. Various efforts, both in Pekalongan city government through the labeling of batik, and ASEPHI in Pekalongan city through the implementation of original batik hologram, has been done to maintain the sustainability of batik. But this has not yet provided optimal results, because it is still found that the fraudulent batik seller who put the original batik label/hologram on batik printing, thus harming the society, harming batik craftsmen/producers and tarnish the batik image of Pekalongan city. This happened because the batik label or the original batik hologram had not been connected to a computer-based information system, so that they cannot monitor and validate the attachment of original batik labels/holograms. For this reason, researchers developed a e-label batik application that was able to be used by the community to scan batik labels that produced by the e-label batik application, so that can know information the authenticity of the batik. The application is also equipped with facilities that provide convenience to monitor, validate, get feedback from the community and become a learning media for the community towards batik. The development of e-label batik applications has gone through the stages of alpha testing and continued with closed beta testing to find out the ideal environment, So that the performance of the batik elabel application is optimal, and can be used properly by the community.

Covid-19 is a new type of mutated virus that has been discovered and studied throughout the world. For the time being, no effective drug has been found to treat or prevent this disease. One way that governments around the world are doing is limiting physical contact with people with COVID-19. Data mining is a computer science to study data and perform extraction to get new knowledge. One technique in data mining is classification. C45 is one of the best classification algorithms. The result of the c45 algorithm can be a decision tree. Decision trees are used because the results can be well represented. and can be easily understood in human language. This study classified the Covid-19 surveillance dataset using the Decission tree. The Covid-19 surveillance dataset was obtained from a public data portal, namely the UCI machine learning repository. This study resulted in better accuracy than previous studies using the same dataset. The level of accuracy obtained by using the decision tree algorithm is 65%. Although in this study the accuracy value has increased by 10%, the level of accuracy is still relatively low. The low level of accuracy is due to the dataset used only has 7 attributes and 14 records

Farmers in the south-west coastal Bangladesh are frequently affected by climate change due to their proximity to the Bay of Bengal and heavy reliance on agriculture for their livelihoods. In this case, farmers need to know the best implementation methods (adaptation strategies) to reduce crop losses in a changing climate. The present research evaluated the perceptions of farmers to climate change and determine the socio-economic factors which influence the farmers in choosing the right adaptation decisions. Data were collected through close-ended and open-ended structured questionnaire from 52 coastal households and analyzed through descriptive statistics and logistic regression using SPSS V.16. Results revealed that almost all farmers perceived increasing temperature and changes in rainfall patterns over the last 15 years. In response to a changing climate, farmers adopted 13 adaptation strategies where irrigation ranked the first and crop insurance was the last. The logit analysis suggests that household age, education, family income, family member, farm size, farming experience, organizational participations, and training received have a significant influence on farmer’s adaptation choices. Despite various support and technological interventions being available, changing weather, natural disaster pattern, lower income, and lack of credit facilities ranked as the highest problems farmers encountered during adaptation. This study helps to identify important household characteristics that can be applied in the future to formulate and implement a successful adaptation policy. Finally, this study recommends that effective training and early warning systems and provision of credit and market access facilities are necessary to enhance farmer’s resilience to climate change.

Questo articolo si propone di riflettere sulla paternità responsabile e sul fenomeno dell’abbandono paterno in una prospettiva sociologica. L’esistenza di questo fenomeno è presunta, accompagnata da un’invisibilità sociale: che esiste, ma non è discussa. Nelle considerazioni finali, si osserva che il fenomeno dell’abbandono paterno si è aggravato dai tempi moderni, ma si hanno tracce della sua esistenza fin dall’antichità greca classica, servendo anche da monito alla necessità di rimuovere questo fenomeno di invisibilità della vita sociale e di incoraggiare modi per superarlo.

Searching for Unfree Families in Thirteenth-Century Episcopal Registers: Demetrios Chomatenos and John Apokaukos
Authors: Leidholm Nathan
Published: January 2023

The legal dossiers of Chomatenos and Apokaukos have been called some of the best sources for the Byzantine family. Yet, despite being produced in a slave-holding society where unfree families continued to exist and unfree members of the household were commonplace, slaves and freedmen are scarcely visible in the cases attested in either corpus. This article seeks to demonstrate that the impressive dossiers of Demetrios Chomatenos and John Apokaukos, when read alongside near-contemporary evidence from other ecclesiastical sources, can in fact shed light on aspects of kinship and family life among enslaved or formerly enslaved individuals and may thus serve as a useful source for the study of Byzantine slavery in the first half of the thirteenth century. Understanding the terminology they employ, which may mask the precise legal status of people, nevertheless reveals aspects of the lived realities of (formerly) enslaved people as members of families, in varying capacities, and the ways in which their lives intersected with the rest of Byzantine society. Likewise, the coincidence of terminology in cases like pallake/concubine further reveals cultural attitudes and expectations of those subsumed under those categories, including current or former slaves.
The Illegitimate Offspring of King John of England Identified from the Rolls
Authors: Turner Ralph V.
Published: January 2023

King John was not unusual among medieval English monarchs for siring illegitimate offspring, among them three sons and a daughter born of aristocratic ladies. Chroniclers and moralists’ charges that John’s sexual predations extended to his barons' wives and daughters became a significant factor in baronial alienation that resulted in the 1215 rebellion. A search of royal records from John’s reign yields names of seven: six sons and one daughter, all acknowledged by him. Records from the reign of his son Henry III reveal three more, two sons and one daughter, a total of ten, a number far smaller than that of hs great-grandfather Henry I, famous for siring over twenty illegitimate children. John’s father Henry II fathered only four or five bastards, one of whom became an earl and another an archbishop. Before the Church won power to regulate marriages by the early thirteenth century, sons of kings, princes, and aristocrats born outside formal marriage experienced little stigma. Possibly due to changing attitudes, John’s bastards never rose in prominence as did earlier monarch’s illegitimate offspring, some of whom played major parts in England’s history. None of John’s illicit sons rose to an earldom or bishopric, although entered the baronial ranks and a daughter married the Welsh prince, Llywelyn. Most of John’s illegitimate sons had military careers, serving their father and their brother as royal household knights. Two sought careers in the Church, but neither rose to high rank.
Virtual Reef Diver: enabling people to help protect the Great Barrier Reef
Authors: Vercelloni Julie , Santos Fernandez Edgar , Mengersen Kerrie
Published: January 2023

Two Sustainable Development Goals are focused directly on combating the impacts of climate change on coral reef communities. These are: providing cost-effective and timely information to reef managers (SDG 13 - climate action) and sustaining healthy coral reefs in the future (SDG 14 - life below water). Citizen science (CS) features prominently in a range of programs that have been developed to address these goals. One such program is Virtual Reef Diver, which is designed to help monitor the health of the Great Barrier Reef in Australia. This program engages citizen scientists in two ways. Scuba-divers are asked to take geo-coded underwater images of the reef and upload them to an online virtual reef. Members of the public across the world are then asked to classify these images with respect to key reef indicators such as coral. Through the lens of a Virtual Reef Diver event held as part of 2021 Australia’s National Science Week, we describe important features of this program that positively address common concerns about CS data, including the scientific trustworthiness of the data, the ability to incorporate these data with other more traditional data sources, and the quantifiable improvement in information about reef health using these data for management decisions. This demonstrates the important role that citizen science can play in achieving SDGs.
SEMIOTIC BROADENING OF SIGN: A SEMIOTIC ANALYSIS OF THE BLACK COLOR-SIGN
Authors: SAFAVI Sarvenaz
Published: January 2023

The purpose of writing this article is to show the symmetrical function of linguistics semantics and semiotics. This article explores how semantic broadening in natural languages can be generalized to semiotics, the study of signs and symbolic communication. This study demonstrates that signs, whether members of verbal or non-verbal systems, can be studied similarly to semantic broadening. After introducing the process of semantic broadening, the discussion of the function of this process in semiotics is narrowed down to a case study of the black color-sign. The research method of this analysis is based on qualitative methodology and by collecting data based on a simple assumption which shows that semiotic broadening is a superordinate term that can have explanatory adequacy and can be expanded to verbal and non-verbal signs.

Authors: TOSUN Akıl Fikret
Published: January 2023

Sinema tarihinde bir tür olarak komedi ve yol filmleri dikkat çekmektedir. Özellikle sessiz sinema dönemi itibariyle komedi türü köklerini Antik Yunan dram sanatının bir türü olarak komedya ve fars geleneğinden almakla birlikte vodvil, burlesk, skeç gibi dram sanatının alt türlerinden ve Commedia dell’arte, parodi ile pandomim gibi oyun biçimlerinden de beslenmiştir. Merkezinde yol, yolcu, araç, seyahat, hareket, kimlik, kültür, özgürlük, dönüşüm, coğrafya vb. olan yol filmleri ise köklerini ağırlıklı olarak western türünden alır. Bazen komedi filmlerinin anlatısının yol ve yol hikayeleri merkezinde inşa edildiği görülmektedir. Bunun sonucu olarak karşımıza gerek komedi filmi gerekse yol filmi ögelerinden oluşan yol komedileri çıkmaktadır. Bu perspektiften bakınca Sinemada yol komedileri melez bir alt tür olarak görülebilir. Bu melez alt tür ile Türk sinemasında da karşılaşılmaktadır.

OTTOMAN’S EXISTENCE IN AFRICA IN THE 19TH CENTURY AND THE IMPORTANCE OF SUEZ CANAL
Authors: SENER Mustafa Burak
Published: January 2023

The 19th century is an important period in terms of Africa becoming the great powers’ focal point. Great powers such as the United Kingdom, France, Portugal, and the Ottoman Empire wanted to have influence in the continent and had conflicts between them. The Suez Canal was very effective in intensifying this conflict. As a matter of fact, the Suez Canal, which connects Africa to the Mediterranean, is of great geopolitical importance. In this direction, with the opening of the Suez Canal on the agenda as a project, a geopolitical conflict occurred between the great powers. The study analyzes how the Suez Canal affected the Ottoman Empire’s presence in Africa in the 19th century. The first part of the study examines the importance of the African continent in the 19th century and the Ottoman interaction with Africa. The second part evaluates the process leading to the opening of the Suez Canal. The third and last part analyzes how the opening of the Suez Canal affected the great powers with an evaluation on the Ottoman axis. As a result, it found that the opening of the canal accelerated the decline and disintegration of the Ottoman Empire because of increasing the interest of other great powers and the desire to establish influence in the region.
Enhancing Heterogeneous Wireless Sensor Networks Using Swarm Intelligence –Based Routing Protocols

Published: January 2023

The design of efficient communication protocols for wireless sensor networks has aroused great interest in the research community, especially in the face of the limited energy of sensor nodes and the frequent change in network topology. Routing remains a challenging problem in wireless communications, as deploying or replacing sensor nodes in hazardous environments is difficult. Many studies have been devoted to alleviate certain limitations, such as clustering to maintain network connectivity, injecting heterogeneity to avoid the rapid death of nodes, or incorporating evolution-based optimization methods to find the best network configuration. This work combined heterogeneity and swarm-based optimization to efficiently balance energy consumption between nodes to increase network reliability. Specifically, this work employed the binary particle swarm optimizer and the binary artificial bees colony optimizer to find approximately the optimal set of cluster heads (CHs) with their optimal number. Based on the probabilistic principle of the heterogeneous protocols: SEP, EDEEC, and BEENISH, a new refined formulation of CHs selection using swarm optimization is proposed. The swarm flight is guided towards the best CHs with an objective function representing a good balance between the initial and residual energy of nodes. Compared to the standard heterogeneous protocols SEP, EDEEC, and BEENISH, the developed protocols significantly perform better in terms of stability (FND), the round of half nodes' death (HND), the network lifetime (LND), and energy saving. Indeed, the BABC-SEP was found 31,66% better than SEP in terms of remaining energy percentage, and CHs selection in EDEEC and BEENISH using BABC improved them by more than 20% in the percentage of remaining energy.

Published: January 2023

A new circular patch antenna with a novel metamaterial structure that achieves high bandwidth and positive gain across the operating band. The proposed antenna was Designed by incorporating three split ring resonators into the patch and fabricating it with 15 ×10 ×1.6 mm3. The use of a metamaterial structure with negative permittivity and permeability reduced mutual coupling in a wideband antenna. The designed antenna shows the isotropic nature at 9.71 GHz in the operating band from 8.80 to 12.89 GHz for X band applications specifically for detecting objects using radars. The optimetrics technique analyzed impedance matching with a good return loss of -30 dB. In comparison to previous works, miniaturization achieved up to 81.94%. The efficiency of 95.6% and isotropic pattern were also achieved at 9.71 GHz using HFSS020R2.

El largo proceso evolutivo combinado con una alta complejidad topográfica y edáfica, así como las condiciones climáticas altamente favorecedoras, han generado en esta región condiciones especiales para una radiación adaptativa de muchos grupos taxonómicos (Gentry, 1982; Lu- teyn, 2002), en la actualidad algunos autores concluyen casi con certeza que aquí se encuentra una de las concentraciones más altas de especies de plantas vasculares aún por descubrir (Myers et al. 2000; Kappelle & Brown, 2001; Neill, 2005). A nivel regional, la mayor riqueza de especies se encuentra en bosques que están entre los 1000 y 2000 m s.n.m (Jørgensen & León-Yánez, 1999; Van der Werff & Consigilio, 2004), mientras que los bosques montanos que se distribuyen desde los 2500 a 3500 m s.n.m y la vegetación de páramo por encima de los 4500 m s.n.m presentan los niveles más altos de endemismo (Lauer et al. 2001; Kessler, 2002). La historia de la vegetación neotropical empieza hace 100 millones de años, periodo en donde sucedieron grandes cambios que establecieron la flora actual del Ecuador. Muchos autores coinciden en la existencia de algunos fenómenos claves que determinaron la distribución actual de los taxas, entre estos principalmente los patrones biogeográficos que dieron paso a intensos procesos de especiación en tiempos relativamente recientes. 392 páginas ISBN: 978-9942-822-25-3 e-ISBN: 978-9942-822-27-7
