ABSTRACT

With the outbreak of COVID-19, people are experiencing increasing physical and mental health issues. Therefore, personal daily healthcare and monitoring become vital for our physical and mental well being. As a combination of the Internet of Things (IoT) and healthcare services, the Internet of Medical Things (IoMT) has emerged to provide intelligent medical services. However, privacy and security concerns have deterred its wide adoption. In this article, we propose a Federated Learning Driven IoMT (FLDIoMT) framework, which aims to support flexible deployment of IoMT services and address the privacy and security issues at the same time. Also, a systematic workflow of IoMT services is proposed to show an efficient data processing and analysis scheme for specific medical applications. Moreover, we demonstrate the feasibility of the proposed FLDIoMT framework by implementing a novel sleep monitoring system called iSmile.

ABSTRACT

Introduction: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV- 2) spilled over to humans via wild mammals, entering the host cell using angiotensin-converting enzyme 2 (ACE2) as receptor through Spike (S) protein binding. While SARS-CoV-2 became fully adapted to humans and globally spread, some mammal species were infected back. The present study evaluated the potential risk of mammals becoming hosts for SARS-CoV-2 through bioinformatics prediction based on ACE2 receptors.

ABSTRACT

Drones are receiving popularity with time due to their advanced mobility. Although they were initially deployed for military purposes, they now have a wide array of applications in various public and private sectors. Further deployment of drones can promote the global economic recovery from the COVID-19 pandemic. Even though drones offer a number of advantages, they have limited flying time and weight carrying capacity. Effective drone schedules may assist with overcoming such limitations. Drone scheduling is associated with optimization of drone flight paths and may include other features, such as determination of arrival time at each node, utilization of drones, battery capacity considerations, and battery recharging considerations. A number of studies on drone scheduling have been published over the past years. However, there is a lack of a systematic literature survey that provides a holistic overview of the drone scheduling problem, existing tendencies, main research limitations, and future research needs. Therefore, this study conducts an extensive survey of the scientific literature that assessed drone scheduling. The collected studies are grouped into different categories, including general drone scheduling, drone scheduling for delivery of goods, drone scheduling for monitoring, and drone scheduling with recharge considerations. A detailed review of the collected studies is presented for each of the categories. Representative mathematical models are provided for each category of studies, accompanied by a summary of findings, existing gaps in the state-of-the-art, and future research needs. The outcomes of this research are expected to assist the relevant stakeholders with an effective drone schedule design. IEEE

ABSTRACT

Tourism has a reasonably severe impact due to physical restrictions during the COVID-19 pandemic. One of the programs responding to this condition is encouraging rural tourism, which has many natural resources. It is considered to be suitable for future tourism models after a reasonably long quarantine period. However, small and medium-sized enterprises (SMEs) that make up most businesses in rural tourism will find it challenging to recover independently. It drives collaborations among the SMEs empowered by information technology, which is known as e-collaboration. It requires an e-collaboration model to guide the SMEs to set up and manage their business in rural tourism. Hence, a study is conducted to identify the dimensions and factors of an e-collaboration model. By implementing Kitchenham's Systematic Literature Review (SLR) guidelines, the dimensions represent technological and non-technological aspects. These are strategic, management, social, technology, and innovation. © 2021 IEEE

ABSTRACT

The growing awareness that biodiversity is a precious global asset to present and future generation and that species's survival and the integrity of habitats and ecosystems are at serious risk, has increased significantly the importance of biodiversity related research. Biodiversity can be defined as the variability among living organism from all sources, including terrestrial, marine and other aquatic ecosystem and the ecological complexes of which they are part;this includes diversity within species between species and of ecosystems. The diversity of life on earth is nearly unimaginable. There is such a wealth of organism that it's a continuous need to keep trace of the diversity and there is always a provision for the discovery of new ones as it is a well-known fact that changing environmental conditions, habitat food and other ecological factors are more than enough to bring out certain definite changes and the accumulation of small changes give rise to a new species. With covid-19 we have seen the damage the diseases can do not only to human health but also to the global economy.By protecting biodiversity in Earth's ecosystem, countries could save lives and money while helping to prevent future pandemics. The present findings add one new species of an acanthocephalan parasite i.e. Raosentis cavasii from fresh water fish Mystus cavasius. It differs from R.thapari in presence of 20 rows of trunk spines instead of 9 rows, in having unequal lemnisci instead of being equal and in their extension upto proboscis receptacle and in the number of hypodermic nuclei 2-3 pairs dorsal and 1 ventral instead of 3 pairs on both sides.

ABSTRACT

Mário C. C. de Pinna, the winner of Robert H. Gibbs, Jr. Memorial Award for Excellence in Systematic Ichthyology, is featured. De Pinna's research interests run the gamut of systematic ichthyology, from phylogenetic relationships, taxonomy, and biogeography, to theoretical considerations of phylogeny reconstruction, species concepts, the history of comparative biology and its place within the sciences. And his contributions across each of these arenas have been profound and impactful. Indeed, while still a graduate student in the joint City University of New York and American Museum of Natural History program, they published a paper on "Concepts and tests of homology in the cladistic paradigm," a contribution that has been cited over 1,093 times since its publication and almost two decades later has been cited 90 times in the past five years alone. His professional career began while an undergraduate with a publication on a cave population of Trichomyctems, and in the ensuing years has published over 90 peer-reviewed papers. Most of these have focused on the broad sweep of catfish systematics from the resolution of basal relationships across the order to numerous analyses of the composition and inter- and intrarelationships of individual catfish families and genera.

ABSTRACT

COVID-19 is the deadly respiratory disease of the century caused by new type unknown origin Coronavirus. The recent effort of the word researchers is toward finding the origin of the virus. The current study investigated the extent of molecular similarity and divergence between SARS-CoV2 and other related Coronavirus. An attempt has been made to investigate the epidemiological study of this new contagious virus using molecular biology techniques. The phylogenetic trees for all human coronaviruses with the novel Coronavirus have been built using a several complete amino acid sequences of the four known structural proteins, S (spike), E (envelope), M (membrane), and N (nucleocapsid). The result of the study revealed that the SARS-CoV2 is related to human SARS-CoV isolated from different countries very cloely, especially those strains recovered from China in recent times, 2020. The evolutionary changes observed in the inserted 23 amino acids in the RNA binding domain (RBD) of the coronvirus spike glycoprotein which cannot be detected in any other human coronavirus. Moreover, the 2019-nCoV is not closely related to other alpha, beta and gamma human Coronavirus, including MERS-CoV. The current study concluded that 2019-nCoV is more likely believed to originated from SARS-CoV. The probability is more vital to be originated from the strain isolated in China in 2020, which is coincident with the spraed of COVID-19 in the same country. The phyloepidemiologic analyses suggested that the coronaviruses are circulating in human hosts evolving gradually by times in response to the different environment stimuli facing the virus inside the host in different geographical areas. Furthermore, the analysis showed the flow of transmission, and evolutionary changes of SARS-CoV2 which may be directed from the transmission of SARS-CoV from human to Bat and Pangolin then jumped to human again in the crowded market Wuhan city in China.

ABSTRACT

Coronavirus Disease 19 (COVID-19) emergence reveals globally a great health issue and due to the limited information and knowledge on the origin of this novel coronavirus 2019 (2019-nCoV). Therefore, this study aims to investigate the evolution and analysis of molecular epidemiology for both Spike and Envelope proteins of 20 available complete genome sequences of different bat coronaviruses including 2019-nCoV in order to find out which type of bat coronaviruses is more likely to be the origin of this new 2019-nCoV and also multiple amino acid sequences of Envelope protein for all bat coronaviruses were aligned for the purpose of finding the greater probability of novel 2019-nCoV original host among bat coronaviruses. Phylogenetic tree analysis for Spike protein revealed that all 2019-nCoV related coronaviruses isolated from these species of species are discovered in China and Hong Kong and the Middle East bat are less likely to contribute in spreading or to become the origin of 2019-nCoV and all coronaviruses that from Hong Kong and China are located into one clade next to the clade that contains 2019-nCoV coronaviruses which indicates that this group of coronaviruses are genetically different for 2019-nCoV;moreover, Hong Kong and USA bat coronaviruses does not contain the bat coronavirus from China and are located into one clade far from the clade that contains 2019-nCoV indicates that all coronaviruses are genetically very different from 2019-nCoV, and USA bat coronavirus may has no role in generating of 2019-nCoV. The phylogenetic trees analysis of Envelope protein showed that Envelope protein of different coronaviruses are more similar in comparison to Spike protein, USA bat coronavirus has a relatively closeness relationship to 2019-nCoV. Furthermore, Envelope protein alignment showed the closely related amino acid sequence which confirms that the outcomes of phylogenetic tree analysis in which that these bat coronaviruses have genetically close relationship together and more interestingly amino acid sequence (MG772934.1) shows 100% identity with the amino acid sequence of 2019-nCoV (NC 045512.2) and the same virus has a close relationship in both Spike and Envelope due to that in both phylogenetic tree analysis are neighbored with 2019-nCoV in the same clade.

ABSTRACT

The pandemic of severe acute respiratory syndrome coronavirus 2 raised the attention towards bacterial coinfection and its role in coronavirus disease 2019 (COVID-19) disease. This study aims to systematically review and identify the pooled prevalence of bacterial coinfection in the related articles. A comprehensive search was conducted in international databases, including MEDLINE, Scopus, Web of Science, and Embase, to identify the articles on the prevalence of bacterial coinfections in COIVD-19 patients from 1 December 2019 until 30 December 2020. All observational epidemiological studies that evaluated the prevalence of bacterial coinfections in patients with COVID-19 were included without any restriction. Forty-two studies including a total sample size of 54,695 were included in the analysis. The pooled estimate for the prevalence of bacterial coinfections was 20.97% (95% CI: 15.95-26.46), and the pooled prevalence of bacterial coinfections was 5.20% (95% CI: 2.39-8.91) for respiratory subtype and 4.79% (95% CI: 0.11-14.61) for the gastrointestinal subtype. The pooled prevalence for Eastern Mediterranean Regional Office and South-East Asia Regional Office was 100% (95% CI: 82.35-100.00) and 2.61% (95% CI: 1.74-3.62). This rate of coinfection poses a great danger towards patients, especially those in critical condition. Although there are multiple complications and adverse effects related to extensive use of antibiotics to treat patients with COVID-19, it seems there is no other option except applying them, and it needs to be done carefully.

ABSTRACT

Learning biology, and in particular systematics, requires learning a substantial amount of specific vocabulary, both for botanical and zoological studies. While crucial, the precise identification of structures serving as evolutionary traits and systematic criteria is not per se a highly motivating task for students. Teaching this in a traditional teaching setting is quite challenging especially with a large crowd of students to be kept engaged. This is even more difficult if, as during the COVID-19 crisis, students are not allowed to access laboratories for hands-on observation on fresh specimens and sometimes restricted to short-range movements outside their home. Here, we present QuoVidi, a new open-source web platform for the organization of large-scale treasure hunts. The platform works as follows: students, organized in teams, receive a list of quests that contain morphologic, ecologic, or systematic terms. They have to first understand the meaning of the quests, then go and find them in the environment. Once they find the organism corresponding to a quest, they upload a geotagged picture of their finding and submit this on the platform. The correctness of each submission is evaluated by the staff. During the COVID-19 lockdown, previously validated pictures were also submitted for evaluation to students that were locked in low-biodiversity areas. From a research perspective, the system enables the creation of large image databases by the students, similar to citizen science projects. Beside the enhanced motivation of students to learn the vocabulary and perform observations on self-found specimens, this system allows instructors to remotely follow and assess the work performed by large numbers of students. The interface is freely available, open-source and customizable. Unlike existing naturalist platforms, allows the educators to fully customize the quests of interest. This enables the creation of multiple teaching scenarios, without being bound to a fixed scope. QuoVidi can be used in other disciplines with adapted quests and we expect it to be of interest in many classroom settings.
