Stability of backscattering coefficient evaluation with clinical ultrasound scanner in homogeneous medium when sound field characteristics differ from reference signal
Authors: Oguri Takuma , Omura Masaaki , Saito Wakana , Yoshida Kenji , Yamaguchi Tadashi
Published: April 2021

We investigated the differences between the transmission (Tx)/reception (Rx) sound fields for target and reference signals using a reference phantom method (RPM) to assess the stability of backscattering coefficient (BSC) evaluation. A clinical ultrasound scanner and two types of phased linear array transducer with low and high frequencies were used to evaluate the BSCs for two types of homogenous phantom with different attenuation coefficients and BSCs. Different Tx/Rx sound fields were reproduced using different combinations of Tx focus depths and aperture sizes. Target signals with Tx conditions that were both the same as and different from those for the reference signals were used to produce signals with different Tx/Rx sound fields. The differences in the Tx/Rx sound fields affected the depth dependence of the evaluated BSC. It was concluded that this can be a factor creating variation in the BSC for homogenous targets.

A simple vision-based navigation and control strategy for autonomous drone racing
Authors: Cyba Artur , Szolc Hubert , Kryjak Tomasz
Published: April 2021

In this paper, we present a control system that allows a drone to fly autonomously through a series of gates marked with ArUco tags. A simple and low-cost DJI Tello EDU quad-rotor platform was used. Based on the API provided by the manufacturer, we have created a Python application that enables the communication with the drone over WiFi, realises drone positioning based on visual feedback, and generates control. Two control strategies were proposed, compared, and critically analysed. In addition, the accuracy of the positioning method used was measured.
The application was evaluated on a laptop computer (about 40 fps) and a Nvidia Jetson TX2 embedded GPU platform (about 25 fps). We provide the developed code on GitHub.
Generation and Transmission Expansion Planning With Respect to Global Warming Potential
Authors: Schwaeppe Henrik , Moser Albert , Paronuzzi Paolo , Monaci Michele
Published: April 2021

As a result of global efforts to reduce greenhouse
gas emissions, future energy system designs must be investigated. However, previous studies in integrated generation and transmission expansion planning neglect indirect emissions and therefore the full global warming potential of system designs. We introduce a linear, single-stage integrated expansion planning model with respect to global warming potential of all components. Neglecting indirect emissions underestimates the global warming potential by more than 20% and the total cost by almost 10% in an exemplary showcase. The inclusion of indirect emissions tightens the emission budget and therefore leads to different system designs.
Energy-Efficient Trajectory Optimization for UAV-Assisted IoT Networks
Authors: Zhang Liang , Celik Abdulkadir , Dang Shuping , Shihada Basem
Published: April 2021

In this paper, we propose and study an energy-efficient trajectory optimization scheme for unmanned aerial vehicle (UAV) assisted Internet of Things (IoT) networks. In such networks, a single UAV is powered by both solar energy and charging stations (CSs), resulting in sustainable communication services, while avoiding energy outage. In particular, we optimize the trajectory design of UAV by jointly considering the average data rate, the total energy consumption, and the fairness of coverage for the IoT terminals. A dynamic spatial-temporal configuration scheme is operated for terminals working in the discontinuous reception (DRX) mode. The module-free, action-confined on-policy and off-policy reinforcement learning (RL) approaches are proposed and jointly applied to solve the formulated optimization problem in this paper. We evaluate the effectiveness of the proposed strategy by comparing it with other dynamic benchmark algorithms. The extensive simulation results provided in this paper reveal that the proposed scheme outperforms the benchmarks in terms of data transmission, energy efficiency and adaptivity of avoiding battery depletion. By deploying the proposed trajectory scheme, the UAV is able to adapt itself according to the temporal and dynamic conditions of communication networks.

Authors: Brock Dawn
Published: April 2021

This article discusses the different types of definitions and how writers use them in online popular science articles. The work breaks definitions down into six different types: prototypical, procedural, delayed, zero, figurative, and chain. Looking at different types of definitions, this article focuses the importance of definitions. It also discusses why specific definitions found in popular science articles are categorized under the different definition types. It undertakes an in-depth analysis of 74 definitions and explains why they belong in the category they were given. As a result, the article highlights the importance of chain definitions— combinations of multiple definitions working together to provide an explanation of a term or concept. Overall, each type of definition is unique and helpful in the process of popularizing science. They give the author freedom to create connections between the scientists and the readers. These connections, in turn, allow for greater understanding between the two. The current project examined 10 articles (roughly 10,600 words analyzed) and 74 definitions.

For the qualitative results of uniform and pointwise approximation obtained in [8], we present here general quantitative estimates in terms of the modulus of continuity and of a K-functional, in approximation by the generalized multivariate Bernstein-Durrmeyer operator Mn,Γn,x, written in terms of Choquet integrals with respect to a family of monotone and submodular set functions, Γn,x, on the standard d-dimensional simplex. If d = 1 and the Choquet integrals are taken with respect to some concrete possibility measures, the estimate in terms of the modulus of continuity is detailed. Examples improving the estimates given by the classical operators also are presented.

First, we briefly mention the basic definitions and results on unit neighborhoods of zero. Next, we show the existence of certain non-trivial complex unit neighborhoods of zero. We expose a generalization of the construction method used on the mentioned particular case. Since this construction may not lead to a unit neighborhood of zero, we develop some necessary conditions. Finally, we describe our heuristic use of Wolfram Mathematica to prove the existence of non-trivial complex unit neighborhoods.

Introduction. Infections by genitopathogens are a frequent reason for consultation in Primary Health Care and in the specialties of Infectious Diseases, Urology, Gynecology, and Dermatology. The most common causes are opportunistic microorganisms and responsible for sexually transmitted infections associated with unprotected sex. The objective is to determine the microorganisms that cause these infections in patients treated at the Hospital Universitario Virgen de las Nieves in Granada and Neisseria gonorrhoeae susceptibility to antibiotics. Material and methods. A transversal-descriptive and retrospective study was carried out, which included the results issued, between January 2018 and December 2019, in the Microbiology Laboratory from all the episodes studied using standardized working procedures. Results. The most frequently detected microorganisms were Gardnerella vaginalis (23.81%) followed by Candida spp. (20.9%), especially in females, and N. gonorrhoeae (11.36%) and Ureaplasma urealyticum (11.99%), in males. Many times, they were presented in combination. Regarding herpes simplex viruses, infection by both species had a similar prevalence (50%) in males, while type 1 was more prevalent (76.52%) in females. The most active antibiotics against N. gonorrhoeae were cefotaxime (98%) and cefixime (100%). Tetracycline (39.02%) a poorly active antibiotic. Conclusions. The most frequent pathogens corresponded to those that usually caused infections in females, although N. gonorrhoeae was the most frequent in males and mixed infections are not an accidental finding. HSV-1 infections were more frequent than HSV-2, confirming the trend of a change in the epidemiology of genital herpes.

Risks of Adopting Automated AIS Applications on the Quality of Internal Auditing
Authors: Qatawneh Adel M.
Published: April 2021

The current study aimed at examining the impact of AIS risks (IT Infrastructure ,Data Entry and Outcome, Internal Operations, Control procedures and tools and Data Security) on quality on internal auditing as a comparison study between Jordan and England. Study adopted quantitative approach and d istributed a questionnaire on (133) internal auditors in Jordan and (331) internal auditors in England. Through SPSS results of study indicated that all adopted risks were found within both samples responded to questionnaire. Both sample also indicated that "internal operations" and "data security" are the most influential risks that may jeopardize quality of internal auditing. Results also indicated differences between impacts of such risks on quality of internal auditing; such risks were attributed to the large population of England compared to Jordan and the intensity of internal auditing in England as higher than Jordan due to the intensity of operations within the country. However, "IT infrastructure" and "data security" appeared to be higher in England compared to Jordan which helped in easing the negative impacts of AIS risks on quality of internal auditing. Study recommended applying restrictions on users to limit the possibility of changing and manipulating data whether by parties inside or outside the organization, in addition to presenting extra efforts in choosing internal auditors in terms of qualifications, experiences and abilities.

Ayfer Kafkas’ın “Esrarname” Roman Serisinde Folklor ve Kütahya Halk Hayatı
Authors: DİNÇ Mustafa
Published: April 2021

Edebi ürünleri üreten sanatçılar içinde bulundukları kültürel çevreden bağımsız düşünülemezler. Bu bakımdan eserlerinde folklor temsillerini yansıtmaları kaçınılmazdır. Bu husus halk bilimi alanında modern edebiyat mahsullerindeki folklorik temsillerin incelendiği pek çok araştırmanın oluşturulmasını gündeme getirmektedir. Özellikle hikâye ve roman türünde bu tipteki araştırmaların daha çok yapıldığı görülmekle birlikte, modern edebiyatın hemen tüm türlerinde folklor ürünlerinin tespit ve tahlil edilmesi mümkündür. Bu çalışma da Ayfer Kafkas’ın tarihi-fantezi kurgu türünde yazmış olduğu, Esrarname I Yasak İlmin Kitabı ve Esrarname II Kayıp Ruhun Zindanı isimli seri romanlarında halk bilimi temsillerini tespit ve tahlil ederek yorumlamayı hedeflemiştir. Bu doğrultuda yapılan taramalar neticesinde tespit edilenler, folklor alanının kadroları çerçevesinde tasnif edilerek yorumlanmış, eserin yansıttığı 18.yy Kütahya halk hayatıyla, günümüz Kütahya’sı arasında birtakım ilgilerin kurulabileceği saptanmıştır. Birbirinin devamı niteliğinde olan serinin kurgusu içerisinde ayrıca halk mimarisi, geçiş dönemleri, giyim kuşam süslenme ve el sanatları, seyirlik türler, halk inançları ve hekimliği ile ilgili temsillerin verildiği görülmüştür. Eserin folklorik anlamdaki bir diğer zenginliğinin ise yoğun gerilimli mitik-mistik anlatımın, anlatı geleneğinin öncül türleri olan masal, efsane ve memorat türlerinden benzer yönler ihtiva etmesidir. Bu bağlamda eserin yazarının aldığı eğitimin ve yetiştiği sosyal çevrenin esere büyük ölçüde ve maharetle yansıtıldığı görülmüştür.
Prospects for Multimessenger Observations of Thorne–Żytkow Objects
Authors: DeMarchi Lindsay , Sanders J. R. , Levesque Emily M.
Published: April 2021

Thorne–Żytkow objects (TŻOs) are a class of stellar object comprised of a neutron star core surrounded by a large and diffuse envelope. Their exterior appearance is identical to red supergiants; the distinctive electromagnetic signature of a TŻO is a suite of unusual chemical abundance patterns, including excesses of Li, Rb, Mo, and Ca. However, electromagnetic observations cannot unambiguously identify the presence of a neutron star core. Detection of continuous gravitational wave emission from a rotating neutron star core would provide strong supporting evidence for the existence of TŻOs. We present a model for gravitational wave detector confirmation of TŻOs and demonstrate that these objects should be detectable with Advanced LIGO. We also investigate possible targets for joint optical and gravitational searches, and comment on prospects for detectability in both current and future gravitational wave detector networks.
L'éthique en contexte info-communicationnel numérique
Authors: Majdouli Zineb , Zetlaoui Tiphaine
Published: April 2021

Notre présente étude vise à explorer les pratiques d’autorégulation éditoriales d’internautes inscrits et actifs sur le réseau socio numérique Facebook. En nous appuyant sur une enquête sociologique réalisée auprès d’étudiants en Master, nous identifions les règles d’interaction qu’ils produisent à partir et indépendamment du cadre formel établi par la plateforme. En articulant la sociologie interactionniste, efficace pour l’observation des échanges et la sociologie éthique pour identifier les valeurs sur lesquelles se construit l’action des internautes, nous examinons les différentes formes de civilités en ligne à l’œuvre sur le réseau social. Nous questionnons les règles éthiques que les usagers se donnent à eux-mêmes de manière plus ou moins consciente dans le cadre de cet espace socio numérique à la fois public et privé où la circulation massive de textes et d’images favorise l’apparition de situations sociales dysphoriques.

Les questions de cultures et de religion font souvent peur aux professionnels en contact avec le public, quel que soit leur secteur d’activité. Mais les occulter ne peut déboucher que sur des malentendus, voire des conflits préjudiciables et douloureux pour tous. Il existe pourtant de nombreuses pistes pour aborder sereinement ce sujet.
De la création et de l’utilité d’un groupe auto-support
Authors: Gaudel Françoise
Published: April 2021

Cet article aborde la naissance d’un groupe auto-support d’aide à l’arrêt du tabac après un parcours de sevrage. « Je ne fume plus ! » est un groupe Facebook francophone, majoritairement féminin, surtout investi par des personnes vivant leurs premiers mois de sevrage. L’arrêt en communauté est un choix engagé des participants, dont la principale attente, à l’entrée dans le groupe, est l’échange avec les pairs. L’homophilie et la fonction auto-support sont les pivots du fonctionnement du groupe, avec un fort soutien émotionnel des membres, entraînant un grand nombre d’interactions. Le groupe est perçu comme une espace de parole dédié au vécu du sevrage tabagique. Les échanges autour des apprentissages expérientiels favorisent l’identification positive des membres et a valeur de consolidation de leurs parcours. Ils participent à la prévention de la rechute, par le croisement de la construction de savoirs, l’engagement solidaire des membres et l’entraide à toute heure. L’information, intégrée au moment où elle peut faire sens dans le vécu du sevrage, est issue non seulement des apports de patients experts sur le groupe, mais aussi de l’ensemble de ces interactions. Elle contribue à renforcer la motivation, le sentiment d’auto-efficacité et la confiance en soi. Patients-experts et professionnels de santé y ont un rôle : la fluidité des échanges et des parcours d’accompagnement entre les acteurs du soin et le groupe « Je ne fume plus ! » passe par le fléchage vers ces professionnels depuis le groupe, et l’utilisation du groupe comme outil d’accompagnement non guidé entre deux entretiens pour les professionnels. Ces différents éléments amènent le membre de la web-communauté à devenir acteur de son sevrage, ils favorisent l’autonomisation des personnes dans ce parcours, par la valorisation de chaque étape, la dédramatisation des difficultés, la mise en avant de l’engagement personnel. L’ empowerment , tant au niveau personnel qu’au niveau collectif, prend ici sens : le membre devient un « e-patient » impliqué dans sa prise en charge, informé, se donnant les moyens d’agir de façon de plus en plus autonome. Nous nous situons dans un espace de réduction des risques liés au tabac et à son usage. Une association permet d’aller plus loin, de former les animateurs. Un groupe d’entraide en réseau social se pose ainsi comme un maillon dans la santé publique, qui doit être reconnu, soutenu et consolidé.
Évaluation de l’impact des traitements résidentiels en matière d’addiction auprès d’une population luxembourgeoise adulte
Authors: Lambrette Grégory , Flayelle Maèva , Billieux Joël
Published: April 2021

Le dispositif socio-sanitaire en matière d’addiction au Grand-Duché de Luxembourg a ceci de particulier qu’une large proportion des programmes résidentiels réalisés par les patients s’effectue, et ce pour divers motifs, au sein de structures localisées à l’étranger. La présente étude rend compte d’une évaluation de l’impact des traitements résidentiels en matière d’addiction auprès d’une population luxembourgeoise adulte. Destinée à l’orientation thérapeutique de patients présentant une addiction liée à l’usage de substances psychoactives, cette étude a permis de constater un certain nombre de changements entre l’entrée et la sortie des structures résidentielles. Les variables symptomatologie, qualité de vie, degré de sévérité de l’addiction, et degré de motivation au changement ont toutes montré une amélioration significative au terme des projets thérapeutiques réalisés. Il ressort donc que les programmes résidentiels sont efficaces en matière d’addiction, ceci même si la pérennité des changements observés demande à être confortée.
L’attention portée aux femmes toxicomanes en situation de maternité : un point sur leur prise en charge
Authors: Laera Angela , Lamborelle Robert , Missonnier Sylvain
Published: April 2021

L’intrication entre toxicomanie et maternité est complexe et touche à de nombreux domaines : pénal, social, médical, sociétal, politique et moral. Cet affrontement entre toxicomanie et maternité vient bouleverser l’image idéalisée de la maternité. Les femmes toxicomanes font souvent l’objet de représentations négatives et stigmatisantes qui viennent déteindre sur leur prise en charge, mettant à mal l’accès à leur parentalité. La clinique de la toxicomanie féminine a permis d’ouvrir un nouveau champ de réflexion pour comprendre la spécificité des conduites toxicomaniaques dans cette population. La grossesse, à travers les intenses bouleversements psychiques qu’elle induit, représente une période favorable pour débuter ou renforcer une prise en charge déjà existante. Cet article se veut être un point sur l’évolution de l’accompagnement proposé aux femmes toxicomanes en situation de maternité, ainsi que le rôle fondamental des professionnels auprès d’elles.
