Joint Calibration and Tomographic Reconstruction for Time-of-Flight Sensor Systems
Authors: pathuri bhuvana venkata , Och Andreas , Schuster Stefan 
Published: June 2022

<p>A typical time-of-flight (ToF) tomography method requires accurate information about the system’s calibration parameters in order to reconstruct the features of interest within a region of interest (RoI). This paper proposes a constrained joint calibration and tomography (CJCT) method based on a separable least squares (SLS) approach for ToF tomographic systems. Contrary to the existing offline and online calibration methods, the proposed method utilizes prior information about the calibration parameters in the form of constraints. The imposed constraints allow for an efficient search for the minimum of the inherent SLS cost function by reducing the system and measurement ambiguities. Thus, the proposed CJCT method can find the optimum values for both tomography and calibration parameters more efficiently compared to unconstrained methods. The general applicability of the proposed method is demonstrated by evaluating it on two applications: tomographic reconstruction of the permittivity distribution in a RoI using ToF measurements from a high resolution millimeter-wave radar system, and the temperature distribution inside an industrial blast furnace using measured and simulated acoustic ToF values. The simulation and experimental results show that the proposed method performs significantly better in terms of tomographic reconstruction accuracy compared to unconstrained methods.</p>
Global Stabilization of Polynomial Systems Using Equilibrium-Independent Dissipativity
Authors: Madeira Diego de S. , Lima Thiago Alves 
Published: June 2022

<p>This work presents a proof that the existence of a sum of squares (SOS) decomposition for a closed-loop (asymptotic) stability condition valid around the origin is equivalent, for input-affine polynomial systems, to the existence of an SOS certificate for a strict dissipation inequality subject to a certain equality constraint. In addition, a new sufficient condition for feedback asymptotic stabilization of nonlinear systems around nonzero equilibria is proposed using the notion of equilibrium-independent dissipativity (EID). Then, this new condition is applied to polynomial systems, specifically. It is proved in this article that the aforementioned SOS certificate for strict dissipativity exists, with a strongly convex energy function, if and only if a certain equilibrium-independent strict dissipativity (EISD) condition also has an SOS decomposition. Consequently, not only the origin, but any assignable equilibrium point can be globally stabilized by an appropriate state feedback. As the systems considered are polynomial, semidefinite programming (SDP) can be used to solve this global stabilization problem. A numerical example provides further evidence on the usefulness of the proposed strategy.</p>
Deeply Supervised Practical Implementation of Violence Detection from Videos for Maximizing Performance
Authors: Baskar Ashwath , P Vigneshwar , K Kanishkar 
Published: June 2022

<p> The purpose of violence detection is to determine whether or not a violent action has occurred. This topic grew in popularity due to the need to develop appropriate and automatic violence detection systems that investigated visual data obtained from security cameras positioned in various regions. To classify the videos into four different crime categories or non-violent, we downloaded 200 videos from multiple sources such as news channel recordings, YouTube, and online posted videos on all other social networking sites. We created four different classes, such as arrest, assault, arson, and abuse, with each class containing 50 videos. This work used pre-trained deep neural networks to provide a low-complexity strategy for detecting violence. </p>

В умовах воєнного стану академії загалом та кожній її установі потрібно мобілізувати внутрішні ресурси і накопичений потенціал з метою максимального прискорення перемоги у війні, нав’язаної Російською Федерацією, та повоєнного відновлення України на високотехнологічній і високодуховній основі, що має й надалі консолідувати українську націю, створювати необхідні умови для входження країни в Євросоюз.
The power of negative and positive episodic memories
Authors: Williams Samantha E. , Ford Jaclyn H. , Kensinger Elizabeth A. 
Published: June 2022

AbstractThe power of episodic memories is that they bring a past moment into the present, providing opportunities for us to recall details of the experiences, reframe or update the memory, and use the retrieved information to guide our decisions. In these regards, negative and positive memories can be especially powerful: Life’s highs and lows are disproportionately represented in memory, and when they are retrieved, they often impact our current mood and thoughts and influence various forms of behavior. Research rooted in neuroscience and cognitive psychology has historically focused on memory for negative emotional content. Yet the study of autobiographical memories has highlighted the importance of positive emotional memories, and more recently, cognitive neuroscience methods have begun to clarify why positive memories may show powerful relations to mental wellbeing. Here, we review the models that have been proposed to explain why emotional memories are long-lasting (durable) and likely to be retrieved (accessible), describing how in overlapping—but distinctly separable—ways, positive and negative memories can be easier to retrieve, and more likely to influence behavior. We end by identifying potential implications of this literature for broader topics related to mental wellbeing, education, and workplace environments.

Published: June 2022

Abstract
We present the primary results from the Dragonfly Edge-on Galaxies Survey, an exploration of the stellar halos of twelve nearby (d < 25 Mpc) edge-on disk galaxies with the Dragonfly Telephoto Array. The edge-on orientation of these galaxies allows their stellar halos to be explored with minimal obscuration by or confusion with the much brighter disk light. Galaxies in the sample span a range of stellar masses from 109.68 to 1010.88
M
⊙. We confirm that the wide range of stellar halo mass fractions previously seen for Milky Way–mass galaxies is also found among less massive spiral galaxies. The scatter in stellar halo mass fraction is large, but we do find a significant positive correlation between stellar halo mass fraction and total stellar mass when the former is measured beyond five half-mass radii. Reasonably good agreement is found with predictions from cosmological hydrodynamical simulations, although observed stellar halo fractions appear to be somewhat lower than expected from these simulations.

Introduction: Neuroprotection is a promising area of adjuvant therapy of ischemic brain lesions. At the same time, among potentially effective neuroprotectors, herbal remedies are distinguished due to their high efficiency and safety of use. In this work, some aspects of the neuroprotective effect of 40% ethanol extract of black walnut bark were investi­gated in comparison with its major component juglone.
Materials and methods: The work was performed on male Wistar rats, which were simulated with cerebral ischemia by irreversible occlusion of the middle cerebral artery. The acute toxicity of the extract was preliminarily evaluated. During the work, the following parameters were determined: changes in the behavior of animals in the Morris water maze, cerebral blood flow, brain necrosis zone area, the activity of mitochondrial complexes, citrate synthase activity, lactic, pyruvic, and ATP concentrations. The activity of the studied extract was compared with juglone in a concentra­tion of 1 mg/kg (per os).
Discussion: The study showed that the use of black walnut bark extract in conditions of cerebral ischemia contributed to an increase in the activity of mitochondrial complexes I-V, citrate synthase, which in turn led to the normalization of aerobic-anaerobic metabolism reactions. The increase in the activity of respiratory complexes is probably mediated by the antioxidant properties of juglone, which is a major component of the test extract of black walnut bark.
Conclusion: Thus, the test extract can be a potentially effective neuroprotective agent and requires further study.
Orientation politique et soutien à l’innovation pédagogique : qui sont les plus réfractaires ?
Authors: Darnon Céline , Sommet Nicolas , Normand Alice , Stanczak Arnaud , Désert Michel 
Published: June 2022

Cette recherche étudie le lien entre orientation politique et attitude vis-à-vis d’une nouvelle méthode pédagogique. Des parents d’élèves ont lu la description d’une nouvelle méthode pédagogique et ont rapporté leur intérêt dans cette méthode ainsi que leur soutien à sa mise en place dans l’école de leurs enfants. En fonction de la condition expérimentale, la méthode était présentée, soit comme égalisant les performances scolaires des élèves issus de milieux favorisés et défavorisés (méthode « égalisante »), soit comme les maintenant (méthode « maintenante »). L’orientation politique des parents était mesurée. Les résultats ont montré que plus leur orientation politique tendait vers la droite, moins les parents étaient intéressés par la méthode et moins ils soutenaient son implémentation dans l’école de leur.s enfant.s. En outre, l’orientation à droite prédisait négativement le soutien à la méthode égalisante, et non à la méthode maintenante. Les implications de ces résultats pour le changement de l’école sont discutées.
Motivation incitatrice : un aperçu historique des enjeux théoriques
Authors: Anselme Patrick 
Published: June 2022

Nous avons toujours tenté d’expliquer l’origine des comportements animaux et humains. Mais c’est seulement au cours du xx e siècle que la science a permis des progrès majeurs dans la compréhension des processus qui les contrôlent. À partir des concepts intuitifs d’instinct et de drive a été élaborée la notion de motivation incitatrice, laquelle suggère que le comportement motivé résulte d’un changement dans la perception de certains stimuli en certaines circonstances. Ces stimuli passent du statut d’objets quelconques à celui de récompenses sans que cela nécessite une « pulsion » interne, un réapprentissage ou l’anticipation d’un plaisir. La motivation incitatrice est un processus inconscient, sous contrôle dopaminergique, qui explique une large gamme de phénomènes – en particulier ceux d’origine pavlovienne. On verra toutefois que toute forme d’attraction pour un stimulus impliquant de la dopamine ne peut se réduire à ce qui est appelé la « saillance incitatrice » du stimulus.
Alger au Sahel : stabilité et sécurité

Published: June 2022

Entourée d'une Libye et d'un Sahel plongés dans la tourmente, Alger tente de redéfinir son rôle régional après la longue parenthèse Bouteflika. Puissance incontournable de la région, elle joue pour ce faire de son héritage d'une diplomatie de dialogue, affirmant de plus en plus ses choix propres : coopérations bilatérales, organisation d'une réponse régionale à l'instabilité, diplomatie économique, dans une logique qui demeure méfiante vis-à-vis des acteurs extérieurs à la zone.
Pratiques et stratégies d’apprentissage d’étudiants de 1re année de Licence et participation à un dispositif « apprendre à apprendre » : étude des déterminants et approche motivationnelle

Published: June 2022

L’intérêt pour la réussite des étudiants de première année universitaire perdure au niveau des politiques publiques en éducation. Il se matérialise entre autres par le déploiement de dispositifs d’aide et de remédiation toujours renouvelés. Ce travail cherche à mettre en lumière quelles sont les stratégies d’études mobilisées par les étudiants. L’enjeu de cet article réside également dans la compréhension des déterminants de ces pratiques chez les étudiants de première année de licence et l’appropriation par ces derniers d’un module « d’apprendre à apprendre ». Un premier aspect du travail montre une utilisation massive de pratiques non efficaces. Par ailleurs, si les résultats confortent des pratiques genrées au bénéfice des filles, ils montrent notamment l’utilisation de pratiques efficaces plus fréquentes chez ces dernières. Le recours à des pratiques efficaces s’avère aussi dépendant de la motivation, du sentiment d’être bon élève et de la possession d’un baccalauréat général. En outre, il est intéressant de constater que les difficultés mentionnées par les étudiants sont finalement celles qui ont fait l’objet des contenus dispensés dans le dispositif d’apprendre à apprendre. Malgré cette adéquation, les étudiants se saisissent assez peu de cette opportunité, en particulier ceux qui en auraient le plus besoin.
An operational excellence strategy implementation model for growth in a volatile, uncertain, complex, and ambiguous environment
Authors: Jengwa Emmanuel , Pellissier Rene 
Published: June 2022

Orientation: The study has been undertaken to design an Operational Excellence (OE) Strategy Implementation Model for Growth in a VUCA (Volatile, Uncertain, Complex, and Ambiguous) Environment. The study was conducted using Johannesburg Stock Exchange (JSE) listed companies.Research purpose: To develop an OE strategy implementation model for organisational growth in a VUCA environment.Motivation of study: Illuminating problems such as the prevailing coronavirus disease 2019 (COVID-19) pandemic are impeding OE strategy implementation by JSE listed organisations, suggesting the fact that existing models do not address changes in VUCA environments.Research design, approach and method: This research collected quantitative data using the questionnaire instrument rolled out through SurveyMonkey to 1000 people working for JSE listed companies implementing Operational Excellence. The data collected from the 430 responses of the sampled 1000 was acceptable according to Krejcie and Morgan (1970) formula which requires 384 as minimum for generalisation. The data was cleaned for analysis using the Stata SE version 15.1 where all variables were transformed into numerical score on the Likert scale. The linear regression of the variables enabled the linkages that resulted in structural relationships. The structural equation modelling (SEM) technique was used to further analyse the structural relationships observed, these relationships enabled the construction of the final model through path analysis.Main findings: The study found that OE strategy can only drive growth through proper implementation, maintenance, and improvements utilising management review of best practices, policies, and procedures on key performance metrics such as revenue, profits and return on investment.Practical/managerial implications: Shortcomings of the existing models were interrogated and gaps found in order to design a more suitable model for growth which takes cognisance of the VUCA Environment.Contribution/value-add: A new model was designed that can be used successfully as a holistic tool in OE to drive growth by practitioners of the industry.

Published: June 2022

Background: Uncorrected refractive error is one of the leading causes of visual impairment. Understanding of the barriers to spectacle usage and attitudes of students towards spectacle use and management strategies can help improve population knowledge and develop school-based programmes to address refractive error.Aim: This study aimed to determine the knowledge, attitudes and practices of university students towards refractive error.Setting: A large university in South Africa.Methods: A quantitative descriptive study was performed via a validated self-administered questionnaire. The survey included questions regarding the knowledge of the participants current status of vision, knowledge on causes of poor vision, accessibility of eye healthcare facilities and attitudes towards spectacle use.Results: Knowledge of participants with respect to the cause of poor vision amongst their peers revealed 63% (n = 189) reporting that digital devices are the major cause of poor vision amongst students, followed by myopia (n = 166) and lastly long-sightedness (n = 117). The majority of participants had adequate knowledge regarding methods of correcting poor vision with 95% listing spectacles as a method of correction followed by contact lenses (n = 250) and surgery (n = 203). There were 29% of participants who reported using spectacles all the time and 22% who reported using spectacles some of the time.Conclusion: The university students are knowledgeable about the causes of poor vision amongst students. Some students have refractive error but display poor attitude and practice towards spectacle wear because they do not wear spectacles as often as they should. Awareness around eye care and spectacle use must be created.

Published: June 2022

Background: There are limited data on the outcomes of rechallenge with anti-tuberculosis therapy (ATT) following anti-tuberculosis drug-induced liver injury (AT-DILI) in a high HIV prevalence setting.Objectives: To describe the outcomes of rechallenge with first-line ATT.Method: Hospitalised participants with AT-DILI who were enrolled into a randomised controlled trial of N-acetylcysteine in Cape Town, South Africa, were followed up until completion of ATT rechallenge. We described rechallenge outcomes, and identified associations with recurrence of liver injury on rechallenge (positive rechallenge).Results: Seventy-nine participants were rechallenged of whom 41 (52%) were female. Mean age was 37 years (standard deviation [s.d.] ±10). Sixty-eight (86%) were HIV-positive, of whom 34 (50%) were on antiretroviral therapy (ART) at time of AT-DILI presentation. Five participants had serious adverse reactions to an aminoglycoside included in the alternate ATT regimen given after first-line ATT interruption: acute kidney injury in three and hearing loss in two. The median time from first-line ATT interruption to start of first-line ATT rechallenge was 13 days (interquartile range [IQR]: 8–18 days). Antiretroviral therapy was interrupted for a median of 32 days (IQR: 17–58) among HIV-positive participants on ART before AT-DILI. Fourteen participants had positive rechallenge (18%). Positive rechallenge was associated with pyrazinamide rechallenge (P = 0.005), female sex (P = 0.039) and first episode of tuberculosis (TB) (P = 0.032).Conclusion: Rechallenge was successful in most of our cohort. Pyrazinamide rechallenge should be carefully considered.
