Published: March 2022

Introduction: The aim of the study was to investigate the dose-dependent actoprotective effect of ATACL on physical performance and psychoemotional status of animals under conditions of exhausting exercise.

Materials and methods: Outbred male mice (23–25 g) were used in the experiment. The test compound in various dosages, as well as the reference drug, were administered intragastrically 60 minutes before the forced swimming test for 10 days of the experiment. At the end of the physical activity, the psychoemotional status of the animals was assessed in the Open Field (OF) and Elevated plus maze (EPM) tests.

Results and discussion: In the course of the experiment, it was found that under conditions of exhausting physical execise, a smooth increase in performance was observed in the group that had received the test compound 4-hydroxy-3,5-di-tert butyl cinnamic acid (ATACL) at a dosage of 100 mg/kg for 10 days. The peak of performance was recorded on the 8th day, which was 47.3% (p<0.05) higher than the physical activity of the mice treated with the reference drug ethylthiobenzimidazole hydrobromide (EBH). When assessing changes in the Open Field test, it was found that the test compound ATACL at a dosage of 100 mg/kg is also a leader in stabilizing the psychoemotional status of the animals, which is reflected in the improvement of the motor activity (the number of sectors crossed by 4.7 times (p< 0.05)), exploratory activity (an increase in the number of «peeps» and rearings by 8.5 times (p<0.05) and 12.7 times (p<0.05), respectively) and changes in the level of anxiety (a 2.5-time decrease in the number of short-term grooming acts (p<0.05)) in comparison with the negative control (NC) group. The results obtained in the EPM test are completely consistent with the results of the OF test; the most pronounced activity was observed for the ATACL compound at a dosage of 100 mg/kg.

Conclusion: Based on the combination of reproducible methods, it can be concluded that the most pronounced actоprotective effect is exerted by the compound at a dosage of 100 mg/kg, not inferior, at the same time, to the reference drug EBН.

Objective.

To investigate demographic, lifestyle, and serologic risk factors for isolated rheumatoid arthritis (RA)–associated bronchiectasis (RA-BR) that is not a result of interstitial lung disease (ILD).

Methods.

We performed a case-control study using patients with RA from the Mass General Brigham Biobank. We reviewed the records of all patients with RA meeting the 2010 American College of Rheumatology/European Alliance of Associations for Rheumatology criteria with computed tomography (CT) chest imaging to identify RA-BR cases and controls with RA and RA-related lung disease. For each patient, the CT chest imaging that was performed closest to enrollment was independently reviewed by 2 radiologists for the presence of RA-related lung diseases. Cases had clinical and radiologic evidence of RA-BR without interstitial lung abnormalities on imaging. Controls had RA and no evidence of bronchiectasis or ILD. We examined the associations between demographic, lifestyle, and serologic factors with RA-BR using multivariable logistic regression.

Results.

We identified 57 cases of isolated RA-BR and 360 RA controls without RA-related lung disease. In multivariable models, RA-BR was associated with older age at RA onset (OR 1.37 per 10 years, 95% CI 1.02–1.82), lower BMI at RA diagnosis (OR 0.94 per kg/m2, 95% CI 0.89–0.99), seropositive RA (OR 3.96, 95% CI 1.84–8.53), positive rheumatoid factor (OR 4.40, 95% CI 2.14–9.07), and positive anticyclic citrullinated peptide (OR 3.47, 95% CI 1.65–7.31). Higher titers of RA-related autoantibodies were associated with higher odds of RA-BR.

Conclusion.

Seropositivity, older age at RA diagnosis, and lower BMI at RA onset were associated with isolated bronchiectasis in RA that was not a result of ILD. These findings expand the list of potential risk factors for RA-BR and suggest a pathogenic link between airway inflammation and RA-related autoantibodies.

Authors: Nash Peter
Published: March 2022

Janus kinase inhibitors ( JAKi; or Jakinibs) have become widely prescribed around the world for a variety of immune-mediated inflammatory diseases, including psoriatic arthritis. A previous noninferiority surveillance study of patients aged > 50 years with rheumatoid arthritis and ≥ 1 additional cardiac risk factor raised a number of safety concerns. This review focuses on available safety data from peer-reviewed publications, as well as the most recent presentations from major conferences highlighting JAKi-associated adverse effects. The safety data for several types of JAKi are reviewed. The latest available safety data for tofacitinib, upadacitinib, filgotinib, deucravacitinib, and brepocitinib is presented. In addition, the findings from the oral surveillance study will be discussed to put safety concerns into context.

Published: March 2022

Since its inception, one of the central missions of the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) has been the development of treatment recommendations for patients with psoriatic arthritis (PsA). The initial guidelines, developed in 2009, were updated in 2015. Because of the abundance of new data concerning the therapeutic approach to PsA, GRAPPA members have been working throughout 2020–2021 to once again update the recommendations. At the GRAPPA 2021 annual meeting, the full committee presented proposals from each of the treatment domain groups, including the comorbidities and related conditions groups, based on previous systematic literature reviews. Overarching principles and summary evidence tables were presented, including results from a GRAPPA membership survey of patients and clinicians to assess levels of agreement. A draft of the figure for the treatment recommendations was presented and discussed with the wider membership.

Published: March 2022

The ability to visualize musculoskeletal structures with high-resolution ultrasound is an asset to understanding the complexity of psoriatic arthritis (PsA). During the 2021 Annual Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) meeting, 3 topics were presented and discussed in the ultrasound workshop: (1) the progress on the Diagnostic Ultrasound Enthesitis Tool (DUET) project; (2) the sonographic evaluation of joints in PsA–GRAPPA joint project; and (3) extrasynovial lesions in PsA. The ultrasound group aims to develop sonographic tools that are feasible and can be used in standard care to diagnose PsA early. The discussions around these topics will shape the group's work toward developing a composite index to diagnose PsA early.

En publiant en 1923 son ouvrage majeur « Je et Tu », Martin Buber propose un nouveau paradigme philosophique autour de la rencontre comme étant le lieu propice au déploiement de l’être, de la connaissance empirique de ce qui fait, selon lui, l’essence de l’Homme : la relation à l’Autre. Cette relation si particulière à soi et à son environnement sera apprivoisée par le champ psychothérapeutique et plus particulièrement par les thérapies humanistes. Nous revenons sur l’apport de ce concept.

Many different operators of fractional calculus have been proposed, which can be organized in some general classes of operators. According to this study, the class of fractional integrals and derivatives can be classified into two main categories, that is, with and without general analytical kernel (introduced in 2019). In this article, we define the Mellin transform for fractional differential operator with general analytic kernel in both Riemann-Liouville and Caputo derivatives of order $ \varsigma\ge0 $ and $ \varrho $ be a fixed parameter. We will also establish relation between Mellin transform with Laplace and Fourier transforms.

In this paper, we establish a qualitative theory for implicit fractional order differential equations (IFODEs) with nonlocal initial condition (NIC) with delay term. Because area related to investigate existence and uniqueness of solution is important field in recent times. Also researchers are using existence theory to derive some prior results about a dynamical problem weather it exists or not in reality. In literature, we have different tools to study qualitative nature of a problem. On the same line the exact solution of every problem is difficult to determined. Therefore, we use technique of numerical analysis to approximate the solutions, where stability analysis is an important aspect. Therefore, we use a tool from non-linear analysis known as topological degree theory to develop sufficient conditions for existence and uniqueness of solution to the considered problem. Further, we also develop sufficient conditions for Hyers- Ulam type stability for the considered problem. To justify our results, we also give an illustrative example.

Published: March 2022

In this manuscript, we analyze the existence, uniqueness and Ulam's stability for Caputo proportional fractional integro-differential equation involving mixed nonlocal conditions with respect to another function. The uniqueness result is proved via Banach's fixed point theorem and the existence results are established by using the Leray-Schauder nonlinear alternative and Krasnoselskii's fixed point theorem. Furthermore, by using the nonlinear analysis techniques, we investigate appropriate conditions and results to study various different types of Ulam's stability. In addition, numerical examples are also constructed to demonstrate the application of the main results.
A new approach for operations on neutrosophic soft sets based on the novel norms for constructing topological structures
Authors: Tran Tram B.T. , Ngo My-Phuong , Bui Quang-Thinh , Snasel Vaclav , Vo Bay
Published: March 2022

Neutrosophic sets have recently emerged as a tool for dealing with imprecise, indeterminate, inconsistent data, while soft sets may have the potential to deal with uncertainties that classical methods cannot control. Combining these two types of sets results in a unique hybrid structure, a neutrosophic soft set (NS-set), for working effectively in uncertain environments. This paper focuses on determining operations on NS-sets through two novel norms. Accordingly, the $ {\rm{min}}-{\rm{n}}{\rm{o}}{\rm{r}}{\rm{m}} $ and $ {\rm{max}}-{\rm{n}}{\rm{o}}{\rm{r}}{\rm{m}} $ are well-defined here for the first time to construct the intersection, union, difference, AND, OR operations. Then, the topology, open set, closed set, interior, closure, regularity concepts on NS-sets are introduced based on these just constructed operations. All the properties in the paper are stated in theorem form, which is proved convincingly and logically. In addition, we also elucidate the relationship between the topology on NS-sets and the fuzzy soft topologies generated by the truth, indeterminacy, falsity degrees by theorems and counterexamples.

We consider the following quasi-linear Schrödinger equation.

\begin{document}
$
\begin{align} i\frac{\partial\psi}{\partial t}+\triangle\psi+\psi\triangle|\psi|^2+|\psi|^{p-1}\psi = 0,x\in \mathbb{R}^D, D\geq1, \;\;\;\;\;\;\;\;\;(Q)\end{align}
$
\end{document}

where $ \psi: \mathbb{R}^+\times \mathbb{R}^D\rightarrow \mathbb{C} $ is the wave function, $ p = 3+\frac{4}{D} $. It is known that the set of standing waves is stable for $ 1 < p < 3+\frac{4}{D} $ and it is strongly unstable for $ 3+\frac{4}{D} < p < \frac{3D+2}{D-2} $. In this paper, we prove that the standing waves are strongly unstable for $ p = 3+\frac{4}{D} $. Moreover, a property on the set of the ground states of (Q) is investigated.
A new perspective on infection forces with demonstration by a DDE infectious disease model
Authors: Cheng Tianyu ,   Department of Mathematics, University of Western Ontario, London, ON, N6A 5B7, Canada, Zou Xingfu
Published: March 2022

In this paper, we revisit the notion of infection force from a new angle which can offer a new perspective to motivate and justify some infection force functions. Our approach can not only explain many existing infection force functions in the literature, it can also motivate new forms of infection force functions, particularly infection forces depending on disease surveillance of the past. As a demonstration, we propose an SIRS model with delay. We comprehensively investigate the disease dynamics represented by this model, particularly focusing on the local bifurcation caused by the delay and another parameter that reflects the weight of the past epidemics in the infection force. We confirm Hopf bifurcations both theoretically and numerically. The results show that, depending on how recent the disease surveillance data are, their assigned weight may have a different impact on disease control measures.

Gene expression data is highly dimensional. As disease-related genes account for only a tiny fraction, a deep learning model, namely GSEnet, is proposed to extract instructive features from gene expression data. This model consists of three modules, namely the pre-conv module, the SE-Resnet module, and the SE-conv module. Effectiveness of the proposed model on the performance improvement of 9 representative classifiers is evaluated. Seven evaluation metrics are used for this assessment on the GSE99095 dataset. Robustness and advantages of the proposed model compared with representative feature selection methods are also discussed. Results show superiority of the proposed model on the improvement of the classification precision and accuracy.
A branch and bound algorithm for optimal television commercial scheduling
Authors: Liao Lu-Wen ,   Department of Intelligent Production Engineering, National Taichung University of Science and Technology, Taichung 40401, Taiwan
Published: March 2022

In the current era of multimedia, television (TV) plays an important role in transmitting advertising messages. In addition, advertising is the primary source of revenue for the TV industry. Thus, a critical issue for TV stations is the scheduling of commercials in suitable advertising breaks on different TV channels to maximize revenue and minimize penalties. This type of TV commercial scheduling problem is similar to the machine scheduling problem, and both have availability constraints. However, the literature on TV commercial scheduling has not considered this perspective. Motivated by this, we consider the problem of scheduling commercials with specific service-level requirements on TV channels while minimizing the maximum lateness. The lateness of a commercial is defined to be its completion time minus its due date, and the maximum lateness is the maximum value of lateness among all commercials. We propose an exact branch and bound algorithm based on the LFJ (least flexible job first)/EDD (earliest due date first) rules and network flow methods, which were developed to solve the machine scheduling problem with availability constraints. Computational analysis shows that the bounding scheme proposed is highly effective, and a very low percentage of nodes is generated by the branch and bound algorithm. The algorithm can obtain an optimal solution for the problem.

The personnel assignment problem in different service industries aims to minimize the staff surplus/shortage costs. However, uncertainty in the staff demand challenges the accomplishment of that objective. This research studies the personnel assignment problem considering uncertain demand and multiskilled workforce configured through a 2-chaining strategy. We develop a two-stage stochastic optimization (TSSO) approach to calculate the multiskilling requirements that minimize the training costs and the expected costs of staff surplus/shortage. Later, we evaluate and compare the performance of the TSSO approach solutions with the solutions of two alternative optimization approaches under uncertainty - robust optimization (RO) and closed-form equation (CF). These two alternative approaches were published in Henao et al. [1] and Henao et al. [2], respectively. In addition, we compare the performance of the TSSO approach solutions with the solution of the deterministic (DT) approach and the solutions of myopic multiskilling approaches. To make performance comparisons between the different approaches, we used both real and simulated data derived from a retail store operating in Chile. The results show that, for different demand variability levels, TSSO, RO, and CF always belong to the set of approaches with the lowest average total cost. That is, in this group, there are no statistical differences from one approach to another, so these approaches are the most cost-effective. We also provide insights to retail decision-makers for addressing two key aspects. First, the methodology allows to address two fundamental multiskilling issues: how much multiskilling to add and how it should be added. Second, it is provided understanding on how to select the most suitable approach according to the balance between the conservatism and the reliability associated with the solutions delivered by each approach. Finally, we identify some methodological challenges for future research, such as the evaluation of k-chaining strategies with $ k\ge 2 $.
Recognition, treatment, and prevention of perioperative anaphylaxis: a narrative review
Authors: Long Erin , Ruiz Juan Camilo , Foglia Julena , Valchanov Kamen , Meikle Andrew
Published: March 2022

Perioperative anaphylaxis events are allergic reactions which occur in the perioperative period when patients are exposed to a multitude of agents, received anesthesia, and undergo a procedure. These reactions are rare and can be life-threatening, with the common signs being hypotension, hypoxia, elevated airway pressures and urticaria. Perioperative anaphylaxis can be mediated by immunoglobulin E (IgE) or non-IgE mechanisms. Globally, the incidence of reactions and frequency of specific triggers varies considerably. Perioperative anaphylaxis events often result in discontinuation of surgery, extended hospital stays, unanticipated intensive care admissions and increased morbidity and mortality. Common causative agents include neuromuscular blocking agents (NMBA's), beta-lactam antibiotics, chlorhexidine, and latex. The primary treatment of perioperative anaphylaxis is removal of the offending agent, epinephrine, and adequate fluid resuscitation. Post-operative workup involves serial serum tryptase measurements, skin testing, in-vitro testing and challenges to determine the culprit agent. Several countries including the UK, Spain, France, Australia, and New Zealand have established guidelines, reporting systems, and specialized clinics dedicated to perioperative hypersensitivity reactions. Future efforts should address diagnostic challenges as well as increasing awareness of other perioperative anaphylaxis triggers. This narrative review will provide an overview of the epidemiology, diagnosis, management, and prevention of perioperative anaphylaxis events.

Published: March 2022

The impact of the use of ICTs in the university context has been investigated for decades, as they are not only tools in themselves, but also generate a new social space and, therefore, a new educational space known among others as virtual education or online learning (OL). Precisely, OL has been presented as an alternative in the historical context originated by the COVID-19 pandemic, which has created an unexpected situation for social structures and their educational institutions. The main goals of the study was to know about the students' perceptions of the educational use of ICTs and educational technologies in times of the COVID-19 pandemic. Some specific objectives of the research were (i) to identify the disposition of the students towards the use of ICTs, (ii) to characterize the Interaction with others through the use of ICTs, and to (iii) identify the interaction of the students with LMS and ICTs. An in-depth theoretical review allowed the authors of this paper to construct an instrument to measure students' perceptions about the use of ICTs and educational technologies in times of the COVID-19 pandemic. This research was financially supported by the German Academic Exchange Service (DAAD) as part of the project “Praxispartnerschaften zwischen Hochschulen und Unternehmen in Deutschland und in Entwicklungsländern ab 2017” (Project Nr. 57334905).
L’Intelligence Artificielle, une opportunité pour l’agriculture au Togo
Authors: SONHAYE Kondi Napo
Published: March 2022

Au Togo, l’agriculture est la principale activité du pays. Elle occupe une place prépondérante dans l’économie. Mais le secteur fait face à de nombreuses difficultés pour assurer l’autosuffisance alimentaire. Les enjeux sont donc innombrables eu égard à la croissance de la population et aux défis climatiques de ces derniers temps. Des procédés intelligents commencent aussi par voir le jour notamment le développement de l’agriculture de précision et l’introduction de l’Intelligence Artificielle (IA) aux méthodes utilisées.L’agriculture de demain ne sera plus seulement une affaire de semis, d’engrais et d’irrigation, mais aussi d’algorithmes et de plateforme. Toute la planète sera concernée par cette transformation numérique qui envahit progressivement le continent africain. Avec ce présent travail, nous avons eu à mener des enquêtes sur le terrain afin de comprendre les enjeux liés au potentiel de développement du secteur agricole togolais par le biais de l’Intelligence Artificielle et les défis à relever afin de favoriser son déploiement. Le but de cette recherche est de savoir si cette nouvelle technologie peut transformer l’agriculture au Togo et si l’IA peut être une opportunité.L’objectif est de pousser la réflexion et l’analyse prospective en matière d’IA en évitant d’appliquer une innovation sans une étude approfondie sur les tenants et les aboutissants. Dans ce contexte, il s’avère pertinent de comprendre les répercussions liées à la mise en œuvre des solutions IA dans le domaine agricole et d’examiner la manière dont celles-ci pourraient répondre aux défis technologiques et ce dans un environnement global affecté, entre autres, par le changement climatique.L’étude effectuée au Togo nous a permis de constater qu’en mesurant et analysant les données du sol telles que la température, les intrants, la météo, les nutriments et la santé végétale, les solutions big data et d’IA aident les agriculteurs à utiliser les fertilisants adéquats par exemple ou à optimiser l’irrigation de leur exploitation agricole indispensable pour une agriculture de précision. Ce faisant, un écosystème technologue est train de se mettre aussi en place avec le développement des plateformes et applications. Cet environnement numérique et intelligent permettra de stoker et traiter les données endogènes sur place afin d’alimenter plusieurs bases de données nécessaires à une meilleure prise de décisions des néo e-agriculteurs et ainsi augmenter leurs performances
Modalités plurielles de l’action institutionnelle et implications sur l’activité enseignante. La dynamique des dispositifs et des agencements
Authors: Rufin Diane
Published: March 2022

Prenant pour cadre l’enseignement primaire genevois, à partir de l’étude des discours officiels et d’une enquête ethnographique, l’article vise à saisir les modalités de l’action institutionnelle envisagées dans la pluralité de leurs formes – en mobilisant le concept de dispositif décliné au pluriel et au singulier – et leurs implications sur l’activité enseignante – en considérant les agencements complexes observés. Dans la première partie, les dispositifs font apparaitre des entités et des fonctions spécifiques comme modes opératoires, ainsi que le changement permanent comme dispositif résiduel. S’ils réorganisent l’activité, les agencements demeurent contrastés, dépendants des configurations et personnalités locales. Dans la deuxième partie, le dispositif apparait hybride, rassemblant dans une apparente cohérence des modalités disparates (des principes, des modes d’action, des règlements). Ces dernières sont diversement appréhendées et configurent l’activité de manière paradoxale. Au final, le dispositif risque d’échapper à tout le monde.

Ensuite, ce texte questionne de nouvelles pistes d’analyses autour des questions de médiations et d’ajustements.
Édito - Questionner les milieux éducatifs par les dispositifs et l'activité
Authors: Cairo Crocco Mariagrazia , Félix Christine , Saussez Frédéric
Published: March 2022

Depuis une trentaine d’années, une transformation en profondeur de l’action publique et des politiques éducatives s’est amorcée : les indicateurs de compétitivité et de performance occupent une place accrue dans un écosystème éducatif désormais organisé et géré par dispositifs. Dans ce dossier thématique, nous nous intéresserons tout particulièrement à cette structuration par dispositifs pour analyser les transformations des relations de pouvoir, des prescriptions, normes et cadres du travail des professionnels de l’éducation ainsi qu’à la manière dont ces transformations contribuent à façonner de nouvelles professionnalités. Il s’agit d’explorer par quels processus et par quels ressorts un dispositif parvient à affecter, au sens de transformer, l’activité des professionnels concernés et des bénéficiaires engagés dans celui-ci. Les analyses proposées concernent le champ de l’enseignement, de l’éducation, de la formation et de l’orientation dans des régions françaises, suisses et québécoises.
Les contrôles aux exportations comme instruments de pouvoir dans la gouvernance de l’Internet
Authors: Perarnaud Clément
Published: March 2022

Cet article porte sur le récent processus de négociations européennes ayant conduit à un renforcement des contrôles visant les exportations de technologies de surveillance numérique hors de l’Union européenne (UE). Illustrant la multiplicité et l’expansion des arènes de la gouvernance d’Internet, ce processus de négociation s’inscrit dans le développement par l’UE d’un arsenal législatif et réglementaire visant à encadrer l’économie numérique, et plus globalement le « cyberespace ». Ce processus de réforme met en lumière les implications directes de la régulation croissante du commerce des technologies de cybersurveillance pour la gouvernance de l’Internet, donnant à voir des formes de contrôles et de régulation dans lesquelles les États sont favorisés, et amplifiant l’importance de la territorialité dans la gouvernance des technologies.This article explores the recent EU negotiation process which has led to tighter controls on the export of surveillance technologies outside of the European continent. Illustrating the multiplicity and expansion of Internet governance arenas, this process is part of the EU’s development of a legislative and regulatory arsenal aimed at regulating the digital economy, and more broadly the "cyberspace. This reform process highlights the direct implications of the growing regulation of the trade in cybersurveillance technologies for Internet governance, showing forms of control and regulation in which states are favored, and amplifying the importance of territoriality in the governance of technologies.

The implementation of the European Project Semester at the University Politehnica of Bucharest has outlined the importance of developing soft skills through project-based learning for 21st century engineering learners. This chapter describes the project conducted by a team of four multinational students in 2018. It aimed to develop soft skills (language, written and oral communication, organization and time-management, research and inquiry, self-assessment and reflection, group participation, and leadership) as well as to foster the necessary professional tools for a smooth insertion into the labor market. The development of a 3D-printed robotic arm with IoT capabilities has proved a useful didactic approach in this sense and, at the same time, an efficient way to meet the future economic and technological demands of our changing world. The main goal was to design an affordable robot arm so that people could buy for any application desired.
Current Inclusive Design Projects for Social Innovation
Authors: Puyuelo Marina
Published: March 2022

The issue of design for social innovation is closely linked to citizen participation and the inclusion of the different groups that make up society, particularly the most disadvantaged or at risk of being marginalized. The new product and service design paradigm requires a specific sensitivity in which education and research have to be combined to produce sustainable innovation. A key aspect in the future of design will be cross-disciplinary knowledge and disciplines more adapted to local needs and specific user groups. Hence, as a matter of constructing the future, it seems that the business model has to be re-invented in collaboration with all stakeholders. This chapter gives a sample of the innovation processes experienced in the EPS program, which reflect the interrelationship between open and participatory design methods linked to the issues of accessibility and inclusion in different contexts.

Published: March 2022

The term “Internet of Things (IoT)” was coined at the start of this century when work was done on MIT Auto-ID Centre to make a smart identification technology, which would help to reduce the error rate, subsequently increasing efficiency. But since then, the concept of IoT has evolved rapidly in various ways, as now with the help of this huge number of small networks which can remain connected to one another and can directly communicate with the main network without any human interaction. In this chapter, the investigation has been carried out to design a printed monopole antenna, which is basically a printed microstrip rectangular patch to support such IoT devices. The proposed antenna was designed and simulated using CST MWS, which shows that the antenna is working effectively in the triple band of frequency. The proposed antenna has the capability to work in the range of 2.4 GHz to 6.9 GHz. The miniature size of the antenna makes it suitable for wireless IoT applications.

Published: March 2022

Wireless microwave power transfer (WMPT) knowledge is measured as one of efficient energy shifting technologies. Power transmission by radio waves dates back to the early 1890s. WMPT had a long history before the recent movement towards it. This chapter proposed that the WMPT can be applied to beam-type point-point technique as well as an energy collecting system fed by broadcasting radio waves and solar powered satellites to power IoT devices. WMPT is an important technology in the practice of rectenna (rectifying antenna) to convert microwave signal to a direct current (DC) signal with good efficiency. This method of transferring the power through wireless medium will minimize the wastage of power.
