Universal Scaling Laws for Solar and Stellar Atmospheric Heating: Catalog of Power-law Index between Solar Activity Proxies and Various Spectral Irradiances
Authors: Toriumi Shin , Airapetian Vladimir S. , Namekata Kosuke , Notsu Yuta
Published: September 2022

The formation of extremely hot outer atmospheres is one of the most prominent manifestations of magnetic activity common to late-type dwarf stars, including the Sun. It is widely believed that these atmospheric layers, the corona, transition region, and chromosphere, are heated by the dissipation of energy transported upwards from the stellar surface by the magnetic field. This is signified by the spectral line fluxes at various wavelengths, scaled with power-law relationships against the surface magnetic flux over a wide range of formation temperatures, which are universal to the Sun and Sunlike stars of different ages and activity levels. This study describes a catalog of power-law indices between solar activity proxies and various spectral line fluxes. Compared to previous studies, we expanded the number of proxies, which now includes the total magnetic flux, total sunspot number, total sunspot area, and the F10.7 cm radio flux, and further enhanced the number of spectral lines by a factor of 2. This provides the data to study in detail the flux–flux scaling laws from the regions specified by the temperatures of the corona (log(T/K) = 6–7) to those of the chromosphere (log(T/K) ∼ 4), as well as the reconstruction of various spectral line fluxes of the Sun in the past, F-, G-, and K-type dwarfs, and the modeled stars.
Heilipus squamosus (LeConte, 1824): clarification of the correct name for the “avocado tree girdler” with updates on its biology and distribution (Coleoptera, Curculionidae, Molytinae, Hylobiini)
Authors: Anzaldo Salvatore , Díaz-Grisales Valentina
Published: September 2022

A single species of the genus Heilipus Germar, 1824 is native to the south-eastern United States and was a pest of avocado in Florida in the mid-20th century. Two names—Heilipus apiatus (Olivier, 1807) and H. squamosus (LeConte, 1824)—have both recently been used as the valid name for this species, with H. apiatus also being recently used as the valid name for a species from French Guiana. Confusion surrounding the correct application of these names and the distribution of these species traces back to an erroneous distribution given in Olivier's 1807 description of H. apiatus and, although some authors clarified this previously, there continues to be confusion concerning the correct name. Outside of avocado-producing areas, this species was rarely collected and little was known about its biology. Recent observations on iNaturalist and BugGuide suggest the species is more widely distributed in the United States and less rare than it was previously thought to be.

Heilipus squamosus (LeConte, 1824) is recognised as the valid name for the sole species of Heilipus occurring in the United States, while Heilipus apiatus (Olivier, 1807) is a very different species from French Guiana. Heilipus squamosus was previously recorded from eight States in the south-eastern United States and, after examining records from natural history collections, iNaturalist, BugGuide and literature sources, the species is newly recorded from an additional seven States: Arkansas, Kansas, Kentucky, Louisiana, Missouri, Oklahoma and Texas. Though native host plants have been unconfirmed by rearing records, the evidence indicating the possible host plants in the plant family Lauraceae is reviewed.
Exploring the predation of large land snails using preyed shell remains from rock anvil sites in a tropical limestone rainforest in Malaysia
Authors: Woo Siew-Yin , Foon Junn Kitt , Liew Thor-Seng
Published: September 2022

The study of prey-predator interactions between land snails and birds offers important insights into evolutionary and ecological relationships. Here, we report a case study of rock anvils presumably used by the birds Myophonus caeruleus and Enicurus ruficapillus in a cave cavity of a limestone hill in Malaysia. We did not detect any other species in the plots and, therefore, based on our short study duration, we cannot rule out the possibility that other species, such as mammals, preyed on the snails. The predated shell remains of four land snails namely, Hemiplecta sp., Cyclophorus perdix perdix, Amphidromus atricallosus perakensis and Cyclophorus semisulcatus, were found around rock anvils in the nine plots. Finally, we discussed the potential and the limitations of using shell remains of preyed land snails for behavioural, ecological and evolutionary studies between land snails and their predators.
Eye lens dose assessment in interventional cardiology
Authors: Zagorska A. , Gelev V. , Jeleva I. , Stoyanov N. , Ivanova D.
Published: September 2022

Introduction: Medical professionals performing fluoroscopy guided interventional procedures in cardiology are exposed to a risk of radiation induced cataract, especially if the eye lens dose exceeds the annual dose limit of 20 mSv. Aim: The aim of the current study is to measure the eye lens exposure in three interventional cardiology departments, to analyze the relationship between patient dose and eye lens dose and to study the effectiveness of lead goggles without side protection. Material and methods: Measurements were performed in three departments with participation of 4 interventional cardiologists and 6 nurses. The exposure of the eye lens was measured with EYE-DTM (Radcard) passive dosimeters. Results: For nurses the annual eye lens dose varied from 1.6 mSv to 4.3 mSv. For the interventional cardiologists the results were between 3.2 mSv and 31.4 mSv. The dose reduction factor of the studied safety goggles without side protection is 1 and 1.1. Conclusions: There is a risk of exceeding the annual exposure limit of 20 mSv among interventional cardiologists The eye lens exposure depends on the workload and the clinical complexity of the procedures, as well as on the use of radiation protection devices. Due to the specifics of the procedures, the use of goggles with side protection is recommended. The eye lens dose for nurses is lower than the annual limit, which can be explained with the larger distance between the patient and the nurses and partial shielding by the main operator. Lead glasses without side shielding are not recommended because the exposure occurs from the side.
Endovascular treatment of subclavian artery stenosis
Authors: Petrov I. , Stankov Z. , Stoykova J. , Zlatancheva G. , Vasilev S. , Tasheva I. , Vaseva K.
Published: September 2022

The most common localizations for upper extremity atherosclerosis are the subclavian artery and the brachiocephalic trunk. Significant stenosis of the subclavian artery occurs in 2% of the population and in 7-11% of patients with manifest cardiovascular disease. Revascularization is indicated in symptomatic or asymptomatic patients with coronary disease with planned surgical revascularization. In addition to atherosclerosis, other causes of the appearance of subclavian artery stenosis include dissection, radiation-induced inflammation of the fibromusculature, and various vasculities, especially Takayasu arteritis. The left subclavian artery is about four times more commonly affected than the right. It usually occurs over the age of 50 years and in 1.5-2 times more common in men than in women. Disease of the subclavian artery is usually focal and the lesion is predominantly in the first 2 cm proximal to the origin of the aorta. Between 2016-2021 in the clinic of cardiology and angiology we treated endovascularly 81 patients (41 men and 40 females, median age 64 ± 11) with either intraluminal balloon dilatation and/or primary stent implantation followed by balloon post dilatation. We achieved a high technical success rate (93.8%) and immediate clinical success, with only a few minor complications. 
Thèses sur l’Écriture

Ces thèses ont été rédigées par les professeurs André Gounelle et François Vouga dans le cadre d’un séminaire qui a été suivi par des étudiants en cinquième année de théologie, et qui avait pour thème : « l’autorité de l’Écriture ». Elles ont été expliquées et discutées en séance, puis partiellement remaniées en tenant compte de ces discussions. Nous avons conservé le caractère schématique (lié au genre littéraire de la thèse) et le vocabulaire technique de ce document de travail 1 .
« En matière de foi »
Authors: Gounelle André
Published: September 2022

La Réforme et, à sa suite, le protestantisme affirment le rôle décisif de la Bible pour la vie chrétienne. En quoi consiste précisément sa fonction et en quoi est-elle déterminante ? André Gounelle répertorie les trois réponses (qu’on peut dissocier ou combiner) qui ont été données à cette question : la première se centre sur l’enseignement doctrinal de l’Écriture ; la deuxième insiste sur sa portée existentielle ; la troisième met l’accent sur son ouverture eschatologique.
L’autorité de l’Écriture. Commentaires
Authors: Vouga François
Published: September 2022

En second commentaire des thèses publiées en 1984 avec André Gounelle, François Vouga propose d’affiner, avec le recul, l’emploi des deux termes d’ autorité et d’ Écriture . Constatant tout d’abord que l’autorité n’existe qu’au moment où elle est reconnue, il souligne que c’est la lecture et le compagnonnage avec l’Écriture qui confère à celle-ci son autorité. Il met en évidence que cette reconnaissance de l’autorité de l’Écriture est solidaire d’un pacte de l’imagination ou d’un pacte de la fiction reconnaissant autorité aux événements dont témoigne ou que déploie l’art littéraire de ses écrits. Un second volet part de l’emploi que les évangiles et les épîtres font du terme d’Écriture. L’Écriture reçoit son sens, son unité et sa cohérence à partir de clés de lecture qui lui sont extérieures et c’est la constitution des différents canons qui donne une valeur universelle d’Écriture à la création personnelle d’œuvres poétiques, artistiques ou littéraires que sont les évangiles ou les épîtres.
Évolution du business modèle d’une PME : quelques enseignements tirés d’un cas
Authors: Thelisson Anne-Sophie , Meier Olivier
Published: September 2022

La performance des entreprises dépend fortement de l’adaptation du business modèle de l’entreprise face aux évolutions de son environnement. À l’aide d’une étude de cas longitudinale menée en temps réel, l’objectif de l’étude est d’analyser le changement de business modèle d’une PME dans un contexte d’évolution de son environnement. Notre analyse se focalise sur les changements volontaires et émergents, et plus spécifiquement encore, sur la nature des injonctions paradoxales (Smith et Lewis, 2011) à l’œuvre dans ce changement de business modèle. Nous montrons que le business modèle de l’entreprise est modifié en fonction de l’évolution de son environnement et des dynamiques intrinsèques à l’organisation (tensions à l’œuvre au sein de l’organisation). L’application de la grille des paradoxes de Smith et Lewis (2011) montre la nature des priorités à gérer.

Elle s’efforce d’appliquer aux processus de verbalisation, une approche originale inspirée de « l’algorithme de Lacan » basée sur le triangle « symbole, imaginaire, réel ». Elle porte sur une analyse des discours-types tenus par ces groupes de sujets-acteurs.
L’approche 2PCA : une piste pour mieux cerner le risque
Authors: Nekka Hadj
Published: September 2022

L’analyse de la littérature sur l’innovation sociale a conduit à proposer un classement des travaux à partir de quatre dimensions : les processus (P), les pratiques sociales innovantes (P), le contexte de l’innovation (C) et les acteurs (A). Cet article montre que ces dimensions constitutives de l’approche 2PCA sont une voie pour mieux identifier les risques dans un contexte d’innovation. L’articulation du risque-innovation en passant par la résilience nous a permis de mettre en évidence des risques qui ont été ensuite confirmés à partir d’une étude de cas. Selon nos premiers résultats, l’innovation sociale est à la fois le reflet d’une entreprise résiliente et un moyen d’identification des risques inhérents à leur fonctionnement.

Introduction. Tout le monde déteste la publicité ?
Authors: Aguilar Anne-Sophie , Challine Éléonore
Published: September 2022

La publicité ne laisse personne indifférent. En partant d’une diatribe de l’historien de l’art Louis Réau contre la publicité (1959), puis des réflexions critiques beaucoup plus tardives de Naomi Klein dans No Logo (2000), l’introduction de ce dossier envisage les cultures publicitaires sous l’angle d’une histoire des réflexions, réactions et émotions que celles-ci ne manquent jamais de susciter. Depuis les opposants à la publicité, en passant par ceux qui ont cherché à distinguer la noblesse de l’art de la vulgarité et de la bassesse publicitaires, jusqu’à ceux qui ont cru, dans l’entre-deux-guerres notamment, que la publicité serait l’art du xx e  siècle, c’est tout cet éventail qui forme notre point de départ. Souvent critiquée et méprisée, la publicité reste un champ à explorer pour l’histoire culturelle et sociale, tant dans ses objets mêmes que dans une relation élargie avec des sociétés, des époques et des lieux divers. Ainsi les cultures publicitaires apparaissent comme un sujet-carrefour, au croisement de plusieurs domaines et champs disciplinaires – terrain d’enquête prometteur sur lequel ce numéro offre une ouverture.
Penser les techniques publicitaires de demain : une exploration des brevets d’invention délivrés en France (1850-1940)
Authors: Canu Roland
Published: September 2022

Nous proposons dans cet article de revisiter un siècle de l’histoire technique publicitaire à partir d’un corpus textuel et iconographique encore inexploité : les brevets d’invention délivrés en France de 1850 à 1940 (source : archives INPI). Ces brevets composent une « collection » capable d’établir un témoignage prenant ses distances avec les médias et les techniques qui ont jusqu’ici retenu l’attention. Comme « mémoire de la création technique », ils dévoilent en effet une variété d’inventions publicitaires méconnues. Derrière les journaux et les affiches prolifèrent des idées techniques qui dessinent un mouvement de modernisation publicitaire précédant puis accompagnant la professionnalisation du secteur au début du xx e  siècle. A ainsi été composé un échantillon de 1 042 brevets qui couvrent près d’un siècle d’inventions. Tous ces brevets ont été lus, codés, puis soumis à des traitements lexicométriques présentés dans cet article. Un tel traitement favorise l’identification et la périodisation de plusieurs périmètres techniques, parmi lesquels ceux de la publicité animée et de la publicité lumineuse qui s’imposent au début du xx e  siècle. Ce faisant, ce récit statistique esquisse un ordre des techniques publicitaires, i.e. une normativité qui se déplace et qui semble tout à la fois stimuler la pensée inventive et en limiter l’amplitude.
Propagande commerciale ou publicité politique ?
Authors: Di Jorio Irene
Published: September 2022

Le fascisme est souvent décrit comme une « période noire » pour la « culture publicitaire » italienne. Pourtant, les activités publicitaires ont connu des développements importants sous le fascisme. Pour en saisir la portée, il faut toutefois dépasser le seul cadre commercial, car celui-ci ne représente qu’une partie limitée du terrain d’exercice du travail publicitaire. Cet article analyse l’émergence d’une « culture publicitaire » en Italie de la Grande Guerre au fascisme. Il interroge la manière dont cette culture se manifeste dans les écrits produits par les publicitaires et/ou destinés aux publicitaires (revues, annuaires, manuels). La perspective diachronique large et l’approche transversale, attentive aux transferts, permettent de cerner les contours d’une « culture publicitaire » internationale et polyvalente, dont les savoirs ont été mis au service de la dictature. Les publicitaires italiens se sont intéressés à la propagande dans le sens politique de l’expression. Ils ont essayé de légitimer leur profession en soulignant l’intérêt stratégique de leurs compétences. Ils ont collaboré à la promotion des « produits nationaux », de l’autarcie économique et de l’idéologie fasciste. Pour ce faire, ils ont mobilisé des connaissances théoriques et techniques aux frontières poreuses, entre propagande commerciale et publicité politique.
Les Établissements Siégel et la devanture publicitaire en France pendant l’entre-deux-guerres
Authors: Napolitano Camille
Published: September 2022

Au tournant du xx e  siècle en France, l’art de la devanture de magasin, qui investit tant l’agencement général de sa façade que son enseigne, sa vitrine et son étalage, fait l’objet de premières expérimentations esthétiques de la part, notamment, d’architectes-décorateurs issus de la mouvance Art nouveau. Mais c’est à la suite du premier conflit mondial, lorsque les créateurs Art déco cherchent à repenser le visage de la ville moderne, que l’étalagisme emprunte un virage artistico-commercial véritablement inédit, en associant désormais à ces réflexions des professionnels du commerce et de la publicité. C’est dans ce contexte que la société des Anciens établissements Siégel & Stockman réunis, spécialisée dans l’aménagement de devantures et dirigée par Victor-Napoléon Siégel, est fondée en 1923. À travers l’étude de ses productions, ses collaborations, ses inventions brevetées et ses publications telles que la revue Parade , le texte fait état du rôle qu’a joué l’entreprise pendant l’entre-deux-guerres français dans la légitimation, la définition et la diffusion d’un art publicitaire de la devanture de boutique, entendu comme un ensemble de pratiques et de stratégies constituant un appareil visuel commercial qui, en investissant subrepticement l’espace public directement dans la rue et indirectement par la photographie, vise à arrêter le passant et à lui plaire pour, finalement, l’inciter encore davantage à l’achat.
De la synesthésie à la suggestion
Authors: Sergent Marion
Published: September 2022

S’installant à Paris en 1924, l’artiste suisse Charles Blanc-Gatti trouve dans le milieu publicitaire les ressources lui permettant de mener à bien ses recherches sur l’application artistique de la synesthésie et la création d’une œuvre synchronisant sons et projections lumineuses. Son retour au pays natal marque son intérêt pour le cinéma : il prend la direction de la Montreux-Color-Film en 1938 et accompagne la promotion de ce nouveau studio par des discours teintés de nationalisme. Blanc-Gatti cherche à s’inscrire dans le nouveau marché du film publicitaire dont il souligne le pouvoir de suggestion sur les foules. Pour autant il ne s’agit pas de créer un art publicitaire mais plutôt de faire primer la dimension esthétique sur le produit. L’analyse des réalisations publicitaires et des textes de cet artiste, qui reprennent des arguments de l’esthétique scientifique et de la psychophysiologie, illustre la porosité entre sphères artistiques et industrielles, tout en permettant de revenir sur des enjeux économiques et politiques de l’entre-deux-guerres.
Francis Ponge et l’histoire littéraire de la publicité
Authors: Boucharenc Myriam
Published: September 2022

Francis Ponge n’a pas partagé l’enthousiasme moderniste de Cendrars, Cocteau ou Mac Orlan pour la publicité. Il la considérait comme une émanation de la société capitaliste qui réduit tout à sa valeur marchande. L’auteur du Parti-pris des choses sera pourtant conduit, par nécessité financière, non seulement à répondre aux sollicitations de la publicité mais à la solliciter à son tour. D’une part il signe des commandes de prestige pour de grandes entreprises, de l’autre il travaille en 1953-1954 dans une agence de publicité, l’OGEP, pour laquelle il rédige de manière anonyme divers projets inédits dont l’édition est actuellement en préparation (éd. Benoît Auclerc, Myriam Boucharenc et Gérard Farasse†). Il s’agit de présenter cet exceptionnel dossier d’archives dans une perspective principalement historique en le situant dans « l’histoire littéraire de la publicité », histoire qui quoique demeurée longtemps occultée s’avère aussi essentielle à la compréhension de l’histoire de la littérature qu’à celle de la publicité.
« Deux millions de Parisiens tenant deux millions de verres noircis »
Authors: Pellarin Charly
Published: September 2022

À la fin du xix e  siècle, et plus particulièrement après 1900, les éclipses deviennent de plus en plus massives, tant par le public qu’elles réunissent que par le bruit qu’elles génèrent dans la presse. En cela, elles nous permettent d’éclairer l’émergence d’une culture de l’événement. L’éclipse de 1912, visible à Paris, provoque une véritable hypertrophie médiatique et fait la une des plus grands titres, le plus souvent au détriment du naufrage du Titanic. Aussi, différents pouvoirs – la République, la presse et la science – investissent de concours cet événement pour faire valoir différents intérêts qui leur sont propres. L’éclipse est notamment l’occasion de célébrer les œuvres républicaines – l’instruction des masses, la démocratisation des loisirs – mais aussi de (ré)affirmer le rôle de la science au sein de la société. La presse à grand tirage y trouve aussi un intérêt commercial, ce qui explique la façon dont celle-ci s’attache à « fabriquer » l’événement. Car c’est bien la diffusion d’un discours médiatique récurrent qui permet de rassembler et de fédérer, en somme de créer cet événement autour de valeurs et de symboles communs. Tout cela montre combien la presse a une emprise sur le quotidien des Français et sur la circulation de l’information, mais aussi qu’elle assure un rôle de tribune pour des discours de légitimation des pouvoirs. C’est en manipulant divers éléments de l’imaginaire social des éclipses, dans une poétique journalistique moderne, que celle-ci parvient à forger un consensus médiatique, une doxa – symptomatique de ce que Géraldine Muhlmann appelle le « journalisme de rassemblement ». Cependant, en contextualisant les poétiques médiatiques et les ensembles discursifs, en croisant les différents types de sources, tout en bénéficiant de la plurivocité du paysage médiatique, on constate que cette doxa est bien souvent déconnectée de la réalité des pratiques, en somme des expériences vécues. La mise en lumière de ces décalages permet de dégager les enjeux qui sous-tendent la promotion et les multiples récupérations de tels événements. En somme, cet article s’attache à décrypter les enjeux des mystifications dont l’éclipse fait l’objet, à une période où elles réunissent un public sans précédent.

Infection of a venous port - beware of the Mycobacterium
Authors: Heng Tseng Hui , Loh Marcus Hin Yeung , Chua Ying Ying , Tan Bien Keem , Tan Bien Soo
Published: September 2022

An 84-year-old female with metastatic left breast cancer underwent a venous port insertion for chemotherapy. The port was inserted using standard techniques with image guidance under local anesthesia. She presented after 36 days with evidence of infection. A limited bedside ultrasound demonstrated free fluid surrounding the port. The port was subsequently removed the same day, at which time pus was expressed from the subcutaneous pocket. The culture from the pus grew Mycobacterium abscessus. She required removal of the port and wound debridement, wound dressings and a prolonged course of antibiotics. Mycobacterium abscessus is a group of rapidly growing, multidrug-resistant, non-tuberculous mycobacteria that are also relatively resistant to standard skin disinfectants. In recent years, this organism has been increasingly reported as the culprit in post-operative or post-procedural infections. Treatment is challenging due to multidrug resistance, and requires an extensive course of intravenous antimicrobial and macrolide-based combination therapy followed by oral antimicrobial therapy. Early treatment is essential as progression may result in disseminated infection. We discuss the peri-operative and post-operative care required in preventing and treating infection with this organism.
Fuzzy Random Periodic Review Mixture Inventory Model With Shortage Dependent Backorder Rate
Authors: Khan Wasim F. , Dey Oshmita
Published: September 2022

In most real-life inventory situations, it is observed that, during stock out period, an increase in the amount of shortage results in a decrease in the rate of backorder incurred. Therefore, backorder rate is dependent on shortages, and it may be assumed to be inversely proportional to the shortages. The present research describes a periodic review inventory model with a mixture of backorder and lost sales where the backorder rate is a control parameter. Furthermore, to incorporate two different types of uncertainties i.e., fuzziness and randomness, here the annual customer demand, lead-time demand and the lead-time plus one period's demand have been assumed to be continuous fuzzy random variable following the normal distribution with associated fuzzy probability density functions. An algorithm has been proposed to find the optimal backorder rate, the optimal period of review along with the target inventory level so that the crisp equivalent of the fuzzy random total annual inventory cost is a minimum.

Authors: Jain Vibha , Kumar Bijendra
Published: September 2022

In recent years, the emergence of the internet of things (IoT) has accelerated the quality of day-to-day tasks. With the rapid development of IoT devices, the cloud computing paradigm has become an attractive solution by facilitating on-demand services. However, the remote location of third-party cloud reduces the overall user experience while increasing the latency involved. Fog computing has been introduced as a promising solution by improving the overall service quality. Fog computing comprises distributed and heterogeneous fog nodes with limited resource capabilities. Therefore, managing fog resources while satisfying users' service quality is a challenging task. This study attempts to conduct a systematic review by examining high-quality research papers published between 2018 and April 2022. This paper aims to address current trends, challenges, and theoretical gaps with a wide range of open issues to guide the researchers and practitioners interested in carrying out the further research in the current domain.

Authors: Shah Adeel , Soomro Musawir Ali , Nazir Urooj , Khan Arham
Published: September 2022

With the world progressing rapidly, the supply chain of various industries globally, especially the pharmaceutical sector, has evolved rapidly. Unlike many developing countries, the global supply chains have been revolutionized using various digital technologies. However, in Pakistan, the pharmaceutical sector to be specific, although growing exponentially, still fails to provide maximum efficiency in their supply chain including minimal traceability and visibility from the company's end. This study illustrates the current scenario of the pharmaceutical sector of Pakistan analyzing the gaps and potential areas for opportunities and improvements. The systematic review of literature and meta-analysis aims to provide a basis to understand the current challenges faced by the companies and help formulate a framework to provide a basis for the implementation of the most suited digital technology such as block chain or QR code to encounter and minimize the counterfeit of drugs, increase traceability and streamlining the processes and entities involved in the supply chain.
Traditional Public-Key Cryptosystems and Elliptic Curve Cryptography
Authors: Lopez Maria Isaura , Barsoum Ayad
Published: September 2022

The need to establish safer communication channels in a world where technological development is progressing in leaps and bounds is indispensable. Thus, implementing cryptographic algorithms, which are more complex to compromise, improves the possibilities of securing our sensitive data. In this paper, the authors analyze the algorithmic foundations and perform a comparative analysis of the traditional public-key cryptographic algorithms (e.g., RSA, ElGamal, Schnorr, DSA) and elliptic curve cryptography with NIST recommended curves. In the study, they focus on six different security strengths: 80-, 96-, 112-, 128-, 192-, and 256-bit key sizes. Moreover, this study provides a benchmark among different curves (NIST, SEC2, and IEFT Brainpool) that can be used with various security levels. The authors study and compare the characteristics and performance of the traditional asymmetric algorithms and the elliptic curve algorithms for information security. The results obtained in this study will be graphically visualized through statistical graphs and tables with quantification response times.

Experimental Study of Location Spoofing and Identity Spoofing Attack in Internet of Things Network
Authors: Mehta Mihir , Patel Kajal
Published: September 2022

IoT devices are placed at open places, generally at where monitoring and controlling of devices from remote location is difficult. Location spoofing is a threat in which an intruder intentionally modifies the contextual information such as geolocation of a device. Location spoofed device will pass faulty data to the base station, and because of that, serious problems such as traffic jam in smart city application, machine malfunctioning in industry application can take place. So decision making in IoT applications to determine correctness of contextual information is a prime concern for smooth functioning of networks. Identity spoofing is a threat in which an attacker captures the identity information of a legal device and can misuse this stolen information for performing various cyber threats such as MITM, key stolen, and replay. The authors have simulated these attacks in Cooja simulator and investigated the performance of the network in the presence of these attacks. The conclusion is that these attacks affect network performance in an adverse way.

Using the SOR Paradigm to Understand User Lurking Behavior in Online Knowledge Communities
Authors: Zhou Tao
Published: September 2022

Users' lurking behaviour may hinder the sustainable development of online knowledge communities. The purpose of this research is to examine users' lurking based on a stimulus-organism-response (SOR) paradigm. The results indicate that both social and technological factors affect anxiety and social network fatigue, both of which further determine lurking behavior. Social factors include social comparison and privacy concerns, whereas technological factors include information overload and function overload. The results imply that online knowledge communities need to be concerned with both perspectives of social and technological factors in order to mitigate users' anxiety and social network fatigue and prevent their lurking behaviour.
Towards a Learner-Managed Education Credentialing System Based on Blockchain
Authors: Zuo Yanjun
Published: September 2022

Traditionally, a learner's education credentials are maintained by each educational institution. When individuals need to prove their education, they rely on their educational institutions to certify their education and learning records. This paper proposes a decentralized, learner-managed education credentialing system based on blockchain, where the learners' credentials are issued once, stored in a distributed system, and the learners have full control over how and who can access their credentials. The authors present the procedures for credential issuance, selective disclosure of an individual's credentials chosen by each learner, and credential verification by a third party. A proof-of-concept smart contract system has been developed to demonstrate the functionality of the proposed framework. The smart contracts are programmed using the Solidity programming language and tested on the Remix IDE. The authors present this simulation of smart contracts to handle entity registration, credential information storage, credential verification, and educational financial transactions.

Authors: Ghojoghi Aynaz , Erfaninejad Maryam , Ahmadpour Ehsan , Nazar Eisa , Barac Aleksandra , Fatahinia Mahnaz
Published: September 2022

Objective:

To evaluate the prevalence of Candida species in cancer patients with candidemia around the world, and to identify related risk factors and their antifungal resistance, with an emphasis on non-albicans Candida species (NACs).

Methods:

The published papers related to the subject were systematically searched in databases of MEDLINE (including PubMed), Web of Science, Scopus, Science Direct, and Google Scholar between the 1st January 2000 and 21st April 2021.

Results:

Among the 4 546 records, 69 studies met the inclusion criteria. The pooled prevalence of NACs in cancer patients with candidemia was 62% (95% CI 58%-67%; I
2=94.85%, P=0.00). Based on type of cancer, the pooled prevalence of NACs in hematologic and solid cancer patients were 68% (95% CI 65%- 70%) and 52% (95% CI 49%-54%), respectively. Among NACs, Candida (C.) parapsilosis was the most frequently isolated organism followed by C. tropicalis and C. glabrata. In addition, the therapeutic usage of antibiotics was found as the most common risk factor, accounting for 85% (95% CI 81%-89%) and central venous catheter accounting for 69% (95% CI 62%-77%).

Conclusions:

The incidence of Candida bloodstream infections among cancer patients is a growing concern, especially when the etiologic agents of candidemia tend to shift towards NACs.
Impact of gamete health on fertilization and embryo development
Authors: Chorya Jaypalsinh B , Sutaria Tarunkumar V , Chaudhari Ravjibhai K , Chaudhari Chandrakant F
Published: September 2022

A genetically and functionally proficient gamete is essential for normal fertilization and embryonic development. Any change in gamete health affects fertilization and subsequent events, including embryonic development, implantation, and successful pregnancy. This present review focuses on the role of gamete health on fertilization and embryo development. Several conventional and advanced methods are used to evaluate the morphology and functions of gametes. The abnormal spermatozoa adversely affect fertilization events, which results in reduced cleavage/blastocyst/ implantation and pregnancy rate during assisted reproductive techniques. Poor oocyte quality is also one of the reasons for infertility, although the oocyte has an innate capacity to repair a certain amount of abnormality of both oocyte and spermatozoa. Therefore, oocyte health carries more responsibilities during fertilization events. The gamete, either spermatozoa or oocyte, should have optimum morphological and functional health to fertilize and develop a competent embryo successfully. Thus, it is of prime importance to consider the gamete health parameters while dealing with infertility.
Anti–Müllerian hormone and antral follicle count predict ovarian response in women less than 45 years following GnRH antagonist multiple–dose protocol
Authors: Laqqan Mohammed M , Yassin Maged M
Published: September 2022

Objective:

To speculate which of the following parameters: antral follicle count (AFC), anti-Müllerian hormone (AMH), follicle- stimulating hormone (FSH) and age can be used as a predictor of ovarian response to gonadotropin-releasing hormone (GnRH) antagonist stimulation multiple-dose protocol in women under 45 years, and to determine the cutoff value of these parameters and their correlations for predicting low and high ovarian response.

Methods:

This prospective study included 462 women with the mean age of (29.3±6.5) years. All women were subjected to the GnRH antagonist stimulation multiple-dose protocol. On the second day of the menstrual cycle, ultrasonography was conducted to determine AFC in both ovaries. Peripheral blood samples were collected to evaluate the level of estradiol, FSH, luteinizing hormone, prolactin, thyroid-stimulating hormone, and AMH. The women were divided into three groups: low response (AHH<1 ng/mL, n=173), normal response (AMH=1.0-3.5 ng/mL, n=175), and high response (AMH >3.5 ng/mL, n=114).

Results:

A significant decrease was found in the age and FSH level in the high response group compared to other groups (P<0.001). Conversely, a significant increase was shown in AMH, estradiol on human chorionic gonadotropin (hCG) day, AFC, mature oocytes, fertilized oocytes, and embryos transferred in the high response group compared to the other two groups (P<0.001). The receiver operating characteristic (ROC) curves demonstrated that AFC and AMH had the highest accuracy, followed by basal FSH level and age in the prediction of low ovarian reserves (P<0.001) with cutoff values of ≤4.50 and ≤0.95 for AFC and AMH, respectively. Moreover, the ROC analysis showed that AFC had the highest accuracy, followed by AMH level and age in the prediction of high ovarian reserves with a cutoff value of ≥14.50, ≥3.63, and ≤27.50 years, respectively (P<0.01). A significant decrease was observed in women's age, estradiol level, and oocyte fertilization rate in pregnant women compared to non-pregnant women (P<0.001).

Additionally, significant negative correlations were found between the AFC, the number of mature oocytes, fertilized oocytes, embryos transferred, and the age of pregnant women (P<0.001).

Conclusions:

AFC and AMH predict low and high ovarian response to GnRH antagonist stimulation multiple-dose protocol in women under 45 years.
Oxytocin improves testicular blood flow without enhancing the steroidogenic activity in Baladi goats
Authors: Hedia Mohamed G. , El-Shalofy Amr S.
Published: September 2022

Objective:

To investigate the effects of a single oxytocin injection on plasma steroid concentrations, testicular blood flow measures (resistive and pulsatility indexes), and testicular echogenicity in Baladi goats.

Methods:

Twelve Baladi goat bucks were randomly allocated into 2 groups and received an intravenous injection of either 0.7 IU/kg oxytocin or normal saline 0.9%. Venous blood samples were collected, and testicular blood flow Doppler parameters (i.e, peak systolic velocity, end-diastolic velocity, time average maximum velocity, resistive index, and pulsatility index) were assessed for supratesticular arteries in the left and right testes immediately before (0), and at 5, 30, 60, and 120 min after injection.

Results:

Plasma concentrations of testosterone significantly decreased in the oxytocin group at 60 min post-treatment compared to the control group, whereas plasma concentrations of estradiol-17 β were not affected (P>0.05). Both resistive index and pulsatility index declined in the oxytocin group at 60 min post­treatment compared to the control group (P<0.05). Testicular pixel intensity increased at 30 min post-treatment in the oxytocin group compared to the control group (P<0.05).

Conclusions:

Oxytocin treatment significantly increases testicular blood flow and decreases plasma testosterone concentrations in male Baladi goats.

Published: September 2022

Objective:

To investigate the contraceptive effect of intratesticular injection of chlorhexidine gluconate in dogs and compare it with that of zinc gluconate neutralized with arginine.

Methods:

Twenty-four sexually mature male mongrel dogs were randomly divided by replicate into four groups (n=6 per group). Group I received intra-testicular injection of 2 mL zinc gluconate (10 mg/mL) neutralized with arginine. Group II received intratesticular injection of 2 mL chlorhexidine gluconate (5% w/v). Group III received intratesticular injection of 2 mL chlorhexidine gluconate (4% w/v). Group IV did not receive any treatment and served as the control group. Testicular morphometry was conducted on day 0, 7, 15 and 30 after treatment. Semen was collected and evaluated on day 0 and 30. Data were analyzed using repeated measures analysis of variance.

Results:

There was no difference in the mean values of various parameters between dogs treated with zinc gluconate and those treated with chlorhexidine gluconate at any of the time points. In dogs treated with zinc gluconate or chlorhexidine gluconate, there was a significant increase in the testicular morphometric parameters on day 7 followed by a significant reduction thereafter (day 15 and 30). In contrast, there was no change in any of the parameters in the control untreated dogs during the course of the study. Compared to the pre-treatment values, the mean scrotal circumference and the mean paired testicular volume and testicular weight on day 30 were significantly lower in the treated dogs. Semen samples collected on day 30 from treated dogs were found to be azoospermic, whereas no change in semen quality was observed in the control untreated dogs.

Conclusions:

Intratesticular injection of chlorhexidine gluconate (5% w/v and 4% w/v) is equally as effective as zinc gluconate neutralized with arginine for chemical contraception in dogs.

Published: September 2022

Arthrogryposis multiplex congenita (AMC) is a congenital disorder characterized by nonprogressive multiple joint contractures affecting one or more areas of the body, muscle weakness, and fibrosis. This term includes a heterogeneous group of diseases, neurological, neuromuscular, and genetic or mechanical origin. Two types of classification have been developed: A clinical one (types I, II, and III) and an etiological one. A multidisciplinary approach is needed for better care and appropriate follow-up. It is a case of AMC type 2A. A girl, with an antecedent of low levels of amniotic fluid, presented at birth with multiple malformations and stiffness of several articulations: bilateral clubfoot, bilateral clubhand, temporomandibular joint involvement, postural torticollis, and congenital hip dislocation. She had also a small persistence of arterial canal and ambiguous external genitalia. The care was performed by a multidisciplinary team including a physiatrist, pediatric surgeon, physiotherapist, prosthetist, and orthotist. In infants with arthrogryposis, joint stiffness is maximal at birth. The first step is passive mobilizations before surgical joint treatment. Azbell et al. found in their study that at 9 months of age, many of this infant's impairments of body structure and function, functional activity limitations, and participation restrictions improved. The program of stretching, muscle strengthening, facilitation of motor skills, orthopedic intervention, and parent education may have contributed to this infant's progress. Prospective intervention studies exploring specific intervention strategies are needed to establish the plan of care for these patients. Arthrogryposis describes a set of joint contractures present from birth and nonprogressive. The common physiopathological mechanism is fetal immobility syndrome. Multidisciplinary care is necessary and should be early and continued to gain maximum autonomy and facilitate social integration.

Published: September 2022

Internal inflammatory root resorption is an uncommon pathology that can progress to the periradicular vicinity. It is frequently asymptomatic and only discovered during a radiological screening. Appropriate and timely diagnosis is extremely crucial in tackling these cases. A perforating internal resorptive cavity in the distal root of the mandibular first molar was successfully managed using a sandwich concept of sectional apical obturation with gutta-percha and Bioceramic sealer followed by the placement of mineral trioxide aggregate in the resorptive cavity.
