Bureaucratic routines and error management in algorithmic systems
Authors: Pääkkönen Juho
Published: November 2021

This article discusses how an analogy between algorithms and bureaucratic decision-making could help conceptualize error management in algorithmic systems. It argues that a view of algorithms as irreflexive bureaucratic processes is insufficient as an account of errors in complex public sector contexts, where algorithms operate jointly with other organizational work practices. To conceptualize such contexts, the article proposes that algorithms could be viewed as analogous to more traditional work routines in bureaucratic organizations. Doing so helps clarify that algorithmic irreflexivity becomes problematic when the coordination of routine work around automation fails. Thus, also the challenges of error management come to concern the wider context of organized work. This argument is illustrated using known examples from the critical literature on algorithms. Finally, drawing on recent studies in routine dynamics, the article formulates empirical research directions on error management in algorithmic systems.

Authors: Shevchenko Volodymyr
Published: November 2021

У статті розглянуто проблему реабілітації дітей з порушеннями слуху, слухопротезованими кохлеарними імплантами, на сучасному етапі. Висвітлено основні аспекти виявлення порушення слуху різного ступеня, надання ранньої допомоги та сучасний метод слухопротезування — кохлеарна імплантація. Розкрито основні показники розвитку слуху у дитини після кохлеарної імплантації та важливість комплексного підходу в реабілітації. Відзначено, що дитина з кохлеарним імплантом може спілкуватися з людьми, чути їх і розуміти. Проте цей метод важливо застосувати в перші три роки життя дитини для розвитку мовних і слухових центрів мозку. У цьому разі за допомогою кохлеарного імпланта дитина навчиться сприймати мову оточення, використовувати мову для спілкування і буде розвиватися нарівні з однолітками, а відповідно й соціалізуватися.У статті наголошується на важливості та необхідності підготовки фахівців для реабілітації таких дітей, впровадження в освітній процес корекційних програм розвитку слухомовленнєвого сприйняття після кохлеарної імплантації, розроблення методичних рекомендацій для фахівців і батьків, літератури навчально-реабілітаційного спрямування.

Internet-based language production research with overt articulation: Proof of concept, challenges, and practical advice
Authors: Vogt Anne , Hauber Roger , Kuhlen Anna K. , Rahman Rasha Abdel
Published: November 2021

Language production experiments with overt articulation have thus far only scarcely been conducted online, mostly due to technical difficulties related to measuring voice onset latencies. Especially the poor audiovisual synchrony in web experiments (Bridges et al. 2020) is a challenge to time-locking stimuli and participants’ spoken responses. We tested the viability of conducting language production experiments with overt articulation in online settings using the picture–word interference paradigm – a classic task in language production research. In three pre-registered experiments (N = 48 each), participants named object pictures while ignoring visually superimposed distractor words. We implemented a custom voice recording option in two different web experiment builders and recorded naming responses in audio files. From these stimulus-locked audio files, we extracted voice onset latencies offline. In a control task, participants classified the last letter of a picture name as a vowel or consonant via button-press, a task that shows comparable semantic interference effects. We expected slower responses when picture and distractor word were semantically related compared to unrelated, independently of task. This semantic interference effect is robust, but relatively small. It should therefore crucially depend on precise timing. We replicated this effect in an online setting, both for button-press and overt naming responses, providing a proof of concept that naming latency – a key dependent variable in language production research – can be reliably measured in online experiments. We discuss challenges for online language production research and suggestions of how to overcome them. The scripts for the online implementation are made available.

O período gestacional é marcado por diversas mudanças morfológicas, biomecânicas e fisiológicas, apesar de ser considerado um evento normal diversos desafios são apresentados a gestante principalmente a lombalgia.  Esse estudo trata-se de uma revisão integrativa da literatura que busca realizar um levantamento acerca dos impactos da dor lombar em gestantes e as intervenções terapêuticas utilizadas. A busca eletrônica foi realizada entre junho e julho de 2021 nas bases de dados: PUBMED, LILACS, SCIELO e PEDro. Foram selecionados artigos dentro dos últimos 5 anos, nos idiomas inglês e português, originais, que estivessem disponíveis na íntegra de maneira gratuita, e publicados em periódicos indexados. A dor lombar possui causa multifatorial que limita significativamente diversas atividades de vida diárias de mulheres grávidas. Sua prevalência dentre os estudos foi alta, com destaque para grávidas multíparas, com histórico de dor lombar em gestações anteriores e lombalgia prévia à gravidez. As intervenções terapêuticas encontradas nos artigos foram o pilates, o kinesio taping, a acupuntura e principalmente exercícios físicos de intensidade baixa a moderada. A partir dos estudos identificados nesta revisão foi possível observar que a dor lombar afeta uma parcela significativa de mulheres durante a gestação, que limita as atividades de vida diária e diminui a capacidade funcional e qualidade de vida. De maneira geral, a implementação de atividades físicas e métodos terapêuticos não medicamentosos apresentam-se como possibilidades eficazes de intervenção para esse público com melhora dos sintomas e do bem estar dessas mulheres.

Com o aumento da transmissão de varíola e febre amarela, a população carioca foi acometida com vasto número de mortes e se viu grande proporção de contágio por essas doenças. Junto a disseminação dessas doenças no Rio de Janeiro estava havendo a destruição dos casebres e cortiços, no centro e o desalojamento da comunidade pobre, somando-se às tensões provocadas pelo desalojamento, deve ser mencionado também, a implantação da Lei de Vacinação Obrigatória, e a população começou a reagir, provocando a revolta da vacina. tem-se que este trabalho busca realizar uma revisão da literatura, sobre a revolta da vacina e seus impactos na população no século XXI. Para tal foi realizado uma busca nos periódicos capes, utilizando os indexadores “revolta da vacina”, “reflexos”, “impactos” e “revoltas” de forma associada utilizando o operador booleano “AND”. Quanto aos filtros utilizados foram o arquivo estar disponível na integra de forma online e escrito na língua portuguesa. Um dos principais planos de Rodrigues Alves, então presidente da República, era atacar os demônios que assolavam toda a capital, nomeadamente de febre amarela, varíola, etc. A modernização do porto e a reconstrução da cidade faziam parte do projeto. Alves teve a grande responsabilidade de manter a limpeza da cidade e prevenir muitas doenças infecciosas, foram Pereira Passos e o médico Osvaldo Cruz são nomeados para a execução conjunta desta reforma sanitária. Por volta de 1903, diversos planos de campanha liderados por Oswaldo Cruz foram apresentados ao Ministério Público para combater o vetor da febre amarela. O serviço de saúde pública deveria prevenir a contaminação dos mosquitos pela doença infecciosa febre amarela, a infecção dos mosquitos infectados e a continuação dos casos esporádicos para garantir a não continuidade da doença durante a epidemia. No caso da varíola, basta vacinar toda a população para controlar a doença.

Are the blood urea nitrogen/creatinine ratio and the mean platelet volume able to act as predictors of mortality and morbidity in patients with upper gastrointestinal bleeding?
Authors: KANTEKİN Burçak , AVCİL Mücahit , KAPÇI Mücahit , BİLGE Adnan , AVCI Sema
Published: November 2021

Background: Upper gastrointestinal (GI) bleeding originates above the Treitz ligament and blood urea nitrogen (BUN)/Creatinine (Cr) ratio ≥30 was shown to indicate the presence of upper GI bleeding and it might be an independent risk factor for mortality. The mean platelet volume (MPV) was reported as an indicator of platelet function and activation and was shown to be useful in the diagnosis and follow-up of vascular-origin disorders. In the present study, we aimed to investigate whether BUN/Cr ratio and MPV were predictors of mortality and morbidity in patients with upper GI bleeding.

Material and Method: This retrospective study enrolled a total of 141 patients admitted to the Emergency Department with symptoms of upper GI bleeding and had undergone endoscopy between January 2013-January 2015. Demographics, hemoglobin, hematocrit, MPV, BUN/Cr, the hospitalization unit, the duration of stay, outcome, and the endoscopy reports of the patients were recorded. Statistical analysis was performed using SPSS 17.0.

Results:  It was found that the MPV level did not predict mortality and morbidity in our patients with upper GI bleeding. The likelihood of active bleeding was higher in patients with a BUN/Cr ratio of above 30 when compared to those with a ratio of below 30.

Conclusion: In patients presenting to the emergency department with symptoms of GI bleeding but without signs of renal failure, calculation of admission BUN/Cr ratio may be beneficial for making treatment and follow-up plans.
Seven cases of imported malaria with recurrence
Authors: KESMEZ CAN Fatma , ALAY Handan , PARLAK Mehmet
Published: November 2021

Malaria is an infectious disease caused by Plasmodium species parasites and transmitted to humans by the Anopheles mosquito. The malaria parasites responsible for infection in humans are Plasmodium vivax, Plasmodium ovale, Plasmodium falciparum, Plasmodium malaria, and Plasmodium knowlesi. Although malaria cases originating from Turkey no longer occur, cases originating from abroad are still seen. This report evaluates the epidemiological and clinical characteristics and histories of seven imported malaria cases. All seven cases in this report had a history of travel to African countries together with fever (>39°C), weakness, headache, tremor, sweating, cough, general body pain, and severe shortness of breath. Appropriate treatment was arranged once the necessary examinations had been performed. All patients but one responded to treatment. The non-responsive patient re-presented after 15 days with similar complaints. Primaquine therapy at 15 mg tablet 2×1 was administered, and that patient was discharged after 14 days. The most effective means of bringing malaria under control involves rapid diagnosis and effective treatment. We wish to emphasize that imported cases may be seen in non-endemic regions due to international travel. The travel history of patients in sporadic regions should be investigated, and malaria should be considered in the presence of fever in order to ensure early diagnosis and treatment.
Prediction of hospitalization and blood transfusion requirement in patients with macroscopic hematuria
Authors: ÇETİNKAYA Hasan Basri , GÜNEŞ Harun
Published: November 2021

Aim: It was aimed to find out simple parameters that can be used in the emergency triage and can discriminate patients requiring hospitalization or blood transfusion (BT) among those presenting with macroscopic hematuria (MH).

Material and Method: Medical records of the patients presenting to the emergency department (ED) with MH were investigated retrospectively. The patients’ vital signs including pulse rate (PR), systolic blood pressure (SBP) and diastolic blood pressure, and laboratory test results including hemoglobin, platelet count and international normalized ratio were recorded. Shock index (SI) was calculated using SBP and PR of each patient.

Results: Seventy seven patients were recruited into the study. PR and SI were found to significantly differ between the patients discharged from the ED and those who needed hospitalization. Hospitalized patients were seen to have higher PR values and SI compared to discharged ones. PR and SI were higher in patients requiring BT compared to those who did not require transfusion.

Conclusion: Use of PR and SI in the emergency triage may be helpful while discriminating patients who need hospitalization or BT among those presenting with MH.
Twistors, Self-Duality, and Spinc Structures
Authors:   Stony Brook University, USA, LeBrun Claude
Published: November 2021

The fact that every compact oriented 4-manifold admits spinc structures was proved long ago by Hirzebruch and Hopf. However, the usual proof is neither direct nor transparent. This article gives a new proof using twistor spaces that is simpler and more geometric. After using these ideas to clarify various aspects of four-dimensional geometry, we then explain how related ideas can be used to understand both spin and spinc structures in any dimension.
Cosmic Flow Measurement and Mock Sampling Algorithm of Cosmicflows-4 Tully−Fisher Catalog
Authors: Qin Fei , Parkinson David , Howlett Cullan , Said Khaled
Published: November 2021

Measurements of cosmic flows enable us to test whether cosmological models can accurately describe the evolution of the density field in the nearby universe. In this paper, we measure the low-order kinematic moments of the cosmic flow field, namely bulk flow and shear moments, using the Cosmicflows-4 Tully−Fisher catalog (CF4TF). To make accurate cosmological inferences with the CF4TF sample, it is important to make realistic mock catalogs. We present the mock sampling algorithm of CF4TF. These mocks can accurately realize the survey geometry and luminosity selection function, enabling researchers to explore how these systematics affect the measurements. These mocks can also be further used to estimate the covariance matrix and errors of the power spectrum and two-point correlation function in future work. In this paper, we use the mocks to test the cosmic flow estimator and find that the measurements are unbiased. The measured bulk flow in the local universe is 376 ± 23 (error) ± 183 (cosmic variance) km s−1 at depth d
MLE = 35 Mpc h
−1, to the Galactic direction of (l, b) = (298° ± 3°, −6° ± 3°). Both the measured bulk and shear moments are consistent with the concordance Λ Cold Dark Matter cosmological model predictions.
The Evolution of Collisionless Magnetic Reconnection from Electron Scales to Ion Scales
Authors: Liu Dongkuan , Huang Kai , Lu Quanming , Lu San , Wang Rongsheng , Ding Weixing , Wang Shui
Published: November 2021

It is generally accepted that collisionless magnetic reconnection is initiated on electron scales, which is mediated by electron kinetics. In this paper, by performing a two-dimensional particle-in-cell simulation, we investigate the transition of collisionless magnetic reconnection from electron scales to ion scales in a Harris current sheet with and without a guide field. The results show that after magnetic reconnection is triggered on electron scales, the electrons are first accelerated by the reconnection electric field around the X line, and then leave away along the outflow direction. In the Harris current sheet without a guide field, the electron outflow is symmetric and directed away from the X line along the center of the current sheet, while the existence of a guide field will distort the symmetry of the electron outflow. In both cases, the high-speed electron outflow is decelerated due to the existence of the magnetic field B

z
, then leading to the pileup of B

z
. With the increase of B

z
, the ions are accelerated by the Lorentz force in the outflow direction, and an ion outflow at about one Alfvén speed is at last formed. In this way, collisionless magnetic reconnection is transferred from the electron scales to the ion scales.
Particle-in-cell Simulation of 3He Enrichment in Solar Energetic Particle Events

Published: November 2021

3He enrichment is one distinctive feature of impulsive solar energetic particle events. This study is designed to investigate the process of plasma wave–particle resonance, which plays a key role in selectively accelerating heavy ions. We apply a 1.5 dimensional particle-in-cell simulation to model the electron-beam–plasma interaction that generates electron and ion cyclotron waves, namely proton and 4He cyclotron waves, whose dispersions are dependent on the magnetization parameter α = ω
pe/Ωce and the temperature ratio τ = T

e

p
. The background particles, e.g., 3He and 4He, resonate with the excited cyclotron waves and experience selective heating or acceleration. Specifically, the resonant modes of 3He ions lead to a more effective acceleration rate compared to those of the 4He ions. The simulation results provide a potential solution for understanding the abundance of heavy ions in the solar wind.

Turbulent Magnetogenesis in a Collisionless Plasma
Authors: Pucci F. , Viviani M. , Valentini F. , Lapenta G. , Matthaeus W. H. , Servidio S.
Published: November 2021

We demonstrate an efficient mechanism for generating magnetic fields in turbulent, collisionless plasmas. By using fully kinetic, particle-in-cell simulations of an initially nonmagnetized plasma, we inspect the genesis of magnetization, in a nonlinear regime. The complex motion is initiated via a Taylor–Green vortex, and the plasma locally develops strong electron temperature anisotropy, due to the strain tensor of the turbulent flow. Subsequently, in a domino effect, the anisotropy triggers a Weibel instability, localized in space. In such active wave–particle interaction regions, the seed magnetic field grows exponentially and spreads to larger scales due to the interaction with the underlying stirring motion. Such a self-feeding process might explain magnetogenesis in a variety of astrophysical plasmas, wherever turbulence is present.
A new species of the genus Tylototriton (Urodela, Salamandridae) from western Thailand

Published: November 2021

We describe a new species of the newt genus Tylototriton from Umphang Wildlife Sanctuary, Tak Province, western Thailand based on molecular and morphological evidence and named here as Tylototriton umphangensissp. nov. The new species is assigned to the subgenus Tylototriton and differs from other species in having dark-brown to blackish-brown body and limbs, truncate snout, prominent antero-medial ends of the expansion of the dentary bones, laterally protruding quadrate regions, indistinct and small rib nodules, a well-segmented vertebral ridge, and rough dorsolateral bony ridges, which are steeper anterior, and curved medially at the posterior ends. The molecular data show that Tylototriton umphangensissp. nov. differs from T. uyenoi sensu stricto by a 5% genetic sequence divergence of the mitochondrial NADH dehydrogenase subunit 2 region gene. The new species and T. uyenoi are both endemic to Thailand, distributed along the Northwest Thai (Dawna) Uplands of Indochina. To clarify the species boundary between Tylototriton umphangensissp. nov. and T. uyenoi, additional field research is needed in adjacent areas. Tylototriton umphangensissp. nov. is restricted to evergreen hill forests in Umphang Wildlife Sanctuary. We suggest that the new species should be classified as Endangered (EN) in the IUCN Red List.
Quality and Safety Education for Nurses (QSEN): The Key is Systems Thinking
Authors: Dolansky Mary , Moore Shirley
Published: November 2021

Over a decade has passed since the Institute of Medicine’s reports on the need to improve the American healthcare system, and yet only slight improvement in quality and safety has been reported. The Quality and Safety Education for Nurses (QSEN) initiative was developed to integrate quality and safety competencies into nursing education. The current challenge is for nurses to move beyond the application of QSEN competencies to individual patients and families and incorporate systems thinking in quality and safety education and healthcare delivery. This article provides a history of QSEN and proposes a framework in which systems thinking is a critical aspect in the application of the QSEN competencies. We provide examples of how using this framework expands nursing focus from individual care to care of the system and propose ways to teach and measure systems thinking. The conclusion calls for movement from personal effort and individual care to a focus on care of the system that will accelerate improvement of healthcare quality and safety.
Les prytanées hellénistiques et le politique. Les cas de Priène et de Magnésie du Méandre
Authors: Bernini Julie
Published: November 2021

L’analyse des fonctions et des usages des prytanées de Priène et de Magnésie du Méandre montre qu’ils furent construits dans les dernières décennies du iii e  siècle av. J.-C. pour être les maisons de la communauté civique dans lesquelles était conservé le foyer commun de la cité, ainsi que des lieux de réceptions honorifiques. Ces prytanées étaient aussi utilisés comme dépôt d’archives et permanence du Conseil et de l’Assemblée. Les activités accueillies par ces édifices les plaçaient donc au cœur de la tension propre au politique hellénistique entre les aspirations individuelles des citoyens et l’affirmation du collectif civique.
L’ Aedes herculis musarum , l’«armonia delle sfere», il calendario
Authors: Marcattili Francesco
Published: November 2021

L’auteur, grâce à un réexamen de quelques événements historiques et de leurs sources littéraires, associe la construction du temple d’Hercule Musarum in Circo Flaminio – qui ne figure pas parmi les prétendus « temples votifs dimicatoires » – à une tentative de réforme du calendrier civil et aux éclipses qui se manifestent à brève distance, en 190 et 188 av. J-C. La chronologie de l’ aedes est donc remise en question pour démontrer comment l’Hercule citharède du cirque Flaminius a été appelé, avec les Camènes de la tradition romaine et les Muses de la tradition grecque, à rétablir à travers la musique « l’harmonie des sphères » de la doctrine pythagoricienne. Une harmonie qui, comme le temps – ordonné par le mouvement des astres et marqué par le calendrier –, devait paraître perdue notamment dans les années de la guerre en Étolie. L’architecture, peu commune, du complexe, où M. Fulvius Nobilior a déposé ses Fasti , est en cohérence avec ce cadre culturel et religieux, conçu avec l’apport décisif d’Ennius. En particulier, le plan circulaire du temple faisait allusion, comme dans d’autres cas connus, à la circularité du planisphère céleste. L’étude s’occupe aussi des interventions de restructuration du sanctuaire par L. Marcius Philippus, descendant de Q. Marcius Philippus qui, pendant sa censure de 164 av. J-C., avait construit le premier solarium horologium réglé sur le méridien de Rome. À travers une série d’observations et de comparaisons, l’auteur peut affirmer que la schola semi-circulaire derrière l’ aedes Herculis Musarum était équipée d’un cadran solaire monumental.
Masculin et féminin : la différence sexuelle à la croisée des discours philosophiques et psychanalytiques
Authors: Smith Claude
Published: November 2021

Cette contribution porte sur les enjeux de l’articulation entre discours philosophiques et discours psychanalytiques dans la réflexion sur la différence sexuelle. Elle s’attache à mettre en évidence quelques évolutions ou ruptures significatives, en termes de succession de générations intellectuelles, entre lesquelles on suggère en même temps quelque dialogue, ou confrontation. Sont ainsi distingués trois temps forts générationnels, à partir de l’examen privilégié de certaines des œuvres les plus emblématiques de la contestation sur le terrain de la différence sexuelle : celles de Simone de Beauvoir, Luce Irigaray et Judith Butler. C’est aussi l’occasion d’évoquer les rapprochements ou oppositions possibles de ces approches avec la thématisation précoce, par Lacan, de la question du genre.
Hétérogénéité hebdomadaire
Authors: Henkin David , Khalifa Jean-Charles
Published: November 2021

L’homme moderne vit sur un rythme hebdomadaire. Bien qu’elle ne soit ni ancrée dans le monde observable ni une subdivision naturelle d’une unité calendaire plus large, la semaine de sept jours, institution anormale, n’en constitue pas moins un cadre indispensable de comptabilisation du temps dans la plus grande partie du monde moderne, avec des conséquences importantes pour l’expérience ordinaire et la conscience temporelle. Il est frappant de constater que la semaine bouleverse les dichotomies critiques qui organisent les études scientifiques du temps et s’intègre mal dans les récits conventionnels de l’histoire de la mesure de ce temps. Les sociologues, historiens et critiques culturels distinguent les expériences anciennes du temps en tant que naturelles, cycliques et hétérogènes, de ses expériences modernes et occidentales, quant à elles artificielles, linéaires et homogènes. Les semaines ne se laissent assimiler à aucun des deux termes de cette dichotomie ; ce sont des cycles artificiels qui imposent néanmoins une hétérogénéité aux jours qui composent la série. La semaine défie également toute classification historique facile. C’est d’une part un très vieux système de suivi invoqué par les critiques traditionnels de la société sécularisée de consommation perpétuelle en tant que rempart contre les empiètements de la modernité. Mais c’est aussi un dispositif mécanique qui s’est révélé particulièrement adapté aux relations de marché, à la réorganisation capitaliste du travail, aux exigences de la communication à distance et aux logiques d’une société impersonnelle.
La semaine, une division pratique mais tardive du temps scolaire ? (XVI e -XXI e siècles)
Authors: Condette Jean-François
Published: November 2021

On assiste sur plusieurs siècles à la mise en place d’un temps scolaire où les unités de décompte sont plurielles, mais qui s’autonomise partiellement du temps de la vie religieuse et de celui de la vie économique, cherchant à renforcer l’efficacité pédagogique. Si l’heure devient une unité de compte majeure, la semaine s’affirme à partir du xix e  siècle, d’abord dans le secondaire puis dans le primaire, comme une référence essentielle qui organise l’année scolaire, sert de cadre à la fabrication des emplois du temps et à la gestion du service des enseignants. Il existe cependant constamment des durées différentes comme le mois, le trimestre, le semestre, qui jouent un rôle non négligeable, alors que la notion d’année reste incontournable pour structurer le parcours scolaire de l’élève. La semaine est soumise à de multiples enjeux qui peuvent s’opposer, au croisement des logiques du respect des rythmes de l’enfant et de l’adolescent, de l’organisation des loisirs familiaux et des intérêts économiques, comme le révèlent les tensions récentes autour de « la semaine de quatre jours ».
Hartung, dans l’ombre de la négritude
Authors: Schlesser Thomas
Published: November 2021

Les liens entre le peintre abstrait Hans Hartung et le mouvement littéraire dit de « la négritude » n’ont jamais été l’objet d’une enquête en profondeur. Pourtant, une recherche au plus près des archives permet de constater que l’artiste a été l’objet d’une vive reconnaissance de la part de Césaire juste après la guerre et de Senghor dans les années 1970-1980. Des projets communs et quelques collaborations ont vu le jour. Surtout, alors que Hartung, politiquement conservateur, peut sembler, à bien des égards, fort éloigné des causes décoloniales, son propre trajet d’Allemand exilé en France et naturalisé après avoir versé son sang pour les alliés contre le nazisme fait écho à celles-ci. D’où la naissance d’affinités et même de rencontres surprenantes, comme celle entre le peintre et Cheikh Anta Diop en 1948 alors que ce dernier n’a que 24 ans. Enfin, c’est en arrière-plan la personnalité extraordinaire de l’historienne de l’art et critique Madeleine Rousseau que permet de mieux faire valoir une telle étude. Ainsi des réseaux trop peu observés apparaîtront ici pour affiner la connaissance de la négritude et de Hans Hartung.
An active set solver for constrained $ H_\infty $ optimal control problems with state and input constraints
Authors: Jiang Canghua , Zhang Dongming , Yuan Chi , Teo Kok Ley
Published: November 2021

This paper proposes an active set solver for \begin{document}$ H_\infty $\end{document} min-max optimal control problems involving linear discrete-time systems with linearly constrained states, controls and additive disturbances. The proposed solver combines Riccati recursion with dynamic programming. To deal with possible degeneracy (i.e. violations of the linear independence constraint qualification), constraint transformations are introduced that allow the surplus equality constraints on the state at each stage to be moved to the previous stage together with their Lagrange multipliers. In this way, degeneracy for a feasible active set can be determined by checking whether there exists an equality constraint on the initial state over the prediction horizon. For situations when the active set is degenerate and all active constraints indexed by it are non-redundant, a vertex exploration strategy is developed to seek a non-degenerate active set. If the sampled state resides in a robust control invariant set and certain second-order sufficient conditions are satisfied at each stage, then a bounded \begin{document}$ l_2 $\end{document} gain from the disturbance to controlled output can be guaranteed for the closed-loop system under some standard assumptions. Theoretical analysis and numerical simulations show that the computational complexity per iteration of the proposed solver depends linearly on the prediction horizon.

Authors: BAEK Youn-Kyoung , LEE Jung-Goo
Published: November 2021

High-performance electromagnetic-wave absorbers are required for the control of millimeter-wave spectra, which will play a big role in future 5G and 6G wireless networks. Traditional absorbing materials comprised of metals or soft ferrites have been developed but their lack of ability to absorb at extremely high frequencies continues to hinder their practical applications. Thus, this article briefly introduces several iron-oxide magnetic materials with millimeter-wave absorbing capability.

Abstract— The use of apps has become increasingly common in higher institutions and often linked with the needs of the current generation. This qualitative study investigates the perception of undergraduate students at a university in Malaysia as part of a need analysis to develop a university orientation app. Fifteen participants were interviewed and the findings suggest that the participants have a positive perception of having the app. The positive perception is mainly based on the needs to navigate around the campus where the apps will help to make the navigation easier and effective by serving as ‘one-stop information center’. In addition to the navigation purpose, the potential users request gamification elements to keep them interested in using the app. This paper concludes that an appealing orientation app for the students should expose them to the university surrounding and at the same time contain gamification elements. 
(Re)monter la parole des acteurs de l’histoire
Authors: Besson Rémy
Published: November 2021

Cet article a pour objet l’évolution des pratiques et des discours portant sur le montage des films de Claude Lanzmann sur la Shoah. Il prend pour étude de cas, une partie de Les Quatre sœurs (2018) intitulée Le Serment d’Hippocrate (89 minutes) qui porte sur le récit de vie d’une survivante d’Auschwitz, Ruth Elias. Cette partie du documentaire est issue d’un tournage que le réalisateur a conduit à Tel-Aviv pour Shoah. Il s’agit ici de se demander si le montage a changé en 2018 et quelles sont les conséquences épistémologiques de cette continuité ou de ces variations dans la pratique et les discours entourant le montage des films de Lanzmann.
Oral History as Creative Practice at Concordia University’s Centre for Oral History and Digital Storytelling
Authors: High Steven
Published: November 2021

Oral history is a field of research that is uniquely positioned to thrive at a time of intense public and scholarly interest in sharing personal stories. Unlike ethnography, oral history has not found an institutional home in North American universities given its often fraught relationship to the history discipline. History is typically grounded in distance—the more the better; whereas oral history is based on the idea of closing distance by learning with the communities we study. Yet oral history is thriving in Canadian universities in the in-between spaces of collaborative cross-disciplinary projects and research centres. After introducing readers to the situation in Canada, the article explores the ways that oral history and storytelling have come together at Concordia University’s Centre for Oral History and Digital Storytelling (COHDS). Oral history is a creative practice, and one of its great strengths is its openness to a diversity of approaches. This can be seen in the range of research-creation projects undertaken by oral historians at Concordia in the classroom and in our communities. Montreal Life Stories was the most ambitious of these projects, recording the life stories of 500 genocide survivors and integrating their stories in a range of public outcomes such as theatre plays, online digital stories, art installations, radio programming, documentary and animated film, and a museum exhibition. The article ends with consideration of the online Living Archives of Rwandan Genocide Exiles and Survivors as well as the new digital tools under development.

Initiée en 1979 à New Haven dans l'État du Connecticut sous l’appellation Holocaust Survivors Film Project (HSFP), la Fortunoff Video Archive for Holocaust Testimonies (FVA) contient à ce jour 4 447 témoignages vidéo, essentiellement de rescapés de la Shoah mais aussi d’autres victimes et témoins des crimes nazis. Conservée depuis 1982 à la bibliothèque de la prestigieuse université Yale, cette collection vidéo désormais numérisée et hébergée sur la plateforme Aviary est consultable depuis 2017 dans plusieurs institutions à Paris. Cet article propose une introduction à l’histoire, aux méthodes, aux usages scientifiques et pédagogiques ainsi qu’aux développements technologiques de ce fonds vidéo. Les recherches qu’il présente reposent notamment sur la consultation de données disponibles sur le site internet actuel des archives, dont les bulletins d’information (newsletters) publiés par le HSFP puis la FVA de 1980 à 2003.

Published: November 2021

Nowadays, many people are suffering from several health related issues in which Coronary Artery Disease (CAD) is an important one. Identification, prevention and diagnosis of diseases is a very challenging task in the field of medical science. This paper proposes a new feature optimization technique known as PSO-Ensemble1 to reduce the number of features from CAD datasets. The proposed model is based on Particle Swarm Optimization (PSO) with Ensemble1 classifier as the objective function and is compared with other optimization techniques like PSO-CFSE and PSO-J48 with two benchmark CAD datasets. The main objective of this research work is to classify CAD with the proposed PSO-Ensemble1 model using the Ensemble Technique.

Published: November 2021

Photovoltaic (PV) array under partial shading conditions (PSCs) has several maximum power points (MPPs) on the power-voltage curve of the PV array. These points; have a unique global peak (GP) and the others are local peaks (LPs). This paper aims to study an improved version of a heuristic optimization technique namely, Invasive Weed Optimization (IWO) to track the global maximum power point (GMPP) of a PV array which is an important issue. The proposed improved IWO (IIWO) algorithm modifies IWO to speed up the convergence and make the system more efficient. In addition to study the effect of changing input parameters of IIWO on its performance. An overall statistical evaluation of IIWO, with standard IWO and Particle Swarm Optimization (PSO) is executed under different shading conditions. The simulation results show that IIWO has faster and better convergence as it can reach the GMPP in less time compared with other techniques.
Sustaining the Image of the City: What Matters More? An Investigation in the City of Colombo
Authors: Rathnasekara S. N. , Munasinghe J. N.
Published: November 2021

How a city is known to its inhabitants is largely impacted by its physical environment and this knowledge in turn, impacts the behavior and the sustainability of the city. From Kevin Lynch’s landmark study in 1960, many studies attempted to explore the ‘image of a city’ and revealed that the image was a collectively held psycho-spatial phenomenon that evolved with the changes take place in its physical environment. Colombo, the primate city of Sri Lanka has experienced a fast growth both internally and externally over the last four decades. A large number of high-rises, modern shopping facilities, etc., have been dramatically changing its physical environment. This study investigated the changes evident in the image of the City of Colombo as a result of ongoing developments through the findings of a survey, carried out during 2019-20 period. Analyzing the free recalling responses of 150 participants from different age and user categories, the study reveals that there is a shift in the constituents of the image of Colombo, and the emerging high-rise developments and modern facilities do have, but only a marginal impact on this shift. What matters more are the spaces and physical elements experienced at the ground level.
Btk Supports Autoreactive B Cell Development and Protects against Apoptosis but Is Expendable for Antigen Presentation

Published: November 2021

Bruton’s tyrosine kinase (Btk) propagates B cell signaling, and BTK inhibitors are in clinical trials for autoimmune disease. Although autoreactive B cells fail to develop in the absence of Btk, its role in mature cells is unknown. To address this issue, a model of conditional removal (Btkflox/Cre-ERT2) was used to excise Btk from mature transgenic B cells that recognize the pathophysiologic autoantigen insulin. Anti-insulin B cells escape central tolerance and promote autoimmune diabetes, mimicking human autoreactive cells. Lifelong Btk deficiency was previously shown to eliminate 95% of anti-insulin B cells, but in this model, mature anti-insulin B cells survived for weeks after targeted Btk deletion, even when competing with a polyclonal repertoire. BCR-stimulated cells could still signal via Syk, PLCy2, and CD22, but failed to upregulate the antiapoptotic protein Bcl-xL, and proliferation was impaired. Surprisingly, Btk-depleted anti-insulin B cells could still present Ag and activate T cells, a critical function in promoting T cell–mediated islet cell destruction. Thus, pharmacologic targeting of Btk may be most effective by blocking expansion of established autoreactive cells, and preventing emergence of new ones.

Rodent mast cells are classified into two major subsets, mucosal mast cells (MMCs) and connective tissue mast cells. MMCs arise from mast cell progenitors that are mobilized from the bone marrow to mucosal tissues in response to allergic inflammation or helminth infection. TGF-β is known as an inducer of MMC differentiation in mucosal tissues, but we have previously found that Notch receptor–mediated signaling also leads to the differentiation. Here, we examined the relationship between Notch and TGF-β signaling in MMC differentiation using mouse bone marrow-derived mast cells (BMMCs). We found that the coexistence of Notch and TGF-β signaling markedly upregulates the expression of MMC markers, mouse mast cell protease (mMCP)-1, mMCP-2, and αE integrin/CD103, more than Notch or TGF-β signaling alone, and that their signals act interdependently to induce these marker expressions. Notch and TGF-β–mediated transcription of MMC marker genes were both dependent on the TGF-β signaling transducer SMAD4. In addition, we also found that Notch signaling markedly upregulated mMCP-1 and mMCP-2 expression levels through epigenetic deregulation of the promoter regions of these genes, but did not affect the promoter of the CD103-encoding gene. Moreover, forced expression of the constitutively active Notch2 intracellular domain in BMMCs showed that Notch signaling promotes the nuclear localization of SMADs 3 and 4 and causes SMAD4-dependent gene transcription. These findings indicate that Notch and TGF-β signaling play interdependent roles in inducing the differentiation and maturation of MMCs. These roles may contribute to the rapid expansion of the number of MMCs during allergic mucosal inflammation.
