Ink Mismatch Detection in Hyperpectral Image using K – means Clustering Algorithm
Authors: Zia Usman 
Published: June 2022

<p>In forensic analysis of any document, Ink mismatch detection provides a very important clue to see whether the document is corrupted or not. In hyperspectral imaging (HSI) ink mismatch detection is used to check whetherthe specific document is written with same pen/ink or different types of pens/inks have been used. In this paper, we show that aHSI of handwritten notes can differentiate between the ink sused to produce the document which are very similar in appearance. The HSI cube we have used for our research has 149 Bands. By using an unsupervised clustering algorithm, we have analyzed the spectral responses of the ink pixels to differentiate between the number of inks used in document. After the successful ink mismatch detection, we have used color labelling to classify the text written with different inks. This technique when applied to a RGB document, is not capable to differentiate between the number of inks used in the document. We hope that our findings and technique will help to examine HSI documents for forensic analysis. </p>

Dinsel Terminolojiyle Yaratılan Kimlik Algısı ve Söylem
Authors: YAMAN Haluk 
Published: June 2022

Kimliğin özgünlüğünden ve farklı değerlerinden bahsederken referans verilen noktalardan birisi kimliğin sahip olduğu dini hassasiyetlerdir. Kimileri bu hassasiyetleri konuşma dilinde kullanarak dini hassasiyetlerle örülü bir kimlik algısı oluşturmak isterken, kimisi de aynı algıyı örtülü şekilde söylem içerisinde sunar. Bu nihayetinde özgürlüğün bir ifadesi olarak insanın kendinde hissettiği sorumluluk halinin farklı şekillerde yansıtılmasıdır. Açık veya örtülü olarak yaratılmak istenen algının siyasi argümanlar ile kurulan bağlantısı, siyasi özgürlük ile söylem özgürlüğünü buluşturmaktadır. Siyasi argümanlar içerisinde öne çıkan değişken ise iktidarların dine bakış açısı paralelinde gelişen söylem dilidir. Kurumsallaşmış bir dinin doktrinleri ile geleneksel doktrinleri içerisine alan söylem dili, kimlik algısında benzer amaçlara hizmet etmektedir. Geleneksel dindarlıktan modern dindarlık üzerine gidilen yolda söylem dili, kimlik üzerinden yaratılmak istenen algıda niyet ve ameller arasındaki ayrımı ortaya koymayı zorlaştırmaktadır. Bu çalışmada, yorumsayıcı (hermeneutik) metodoloji kullanılarak, söylem dilinde yer verilen dini terminolojinin kimlik algısı üzerinde bir etki yarattığına dair bir yorum geliştirilmek istenmektedir.

Published: June 2022

Background: Empirical studies involving human participants need to follow procedures to avoid causing harm to the subjects. However, it is not always clear how researchers should report these procedures.
Aim: This study investigates how researchers report ethical issues in the software engineering journal publications, particularly informed consent, confidentiality, and anonymity.
Method: We conducted a literature review to understand the reporting of ethical issues in software engineering journals. In addition, in a workshop, we discussed the importance of reporting the different ethical issues.
Results: The results indicate that 49 out of 95 studies reported some ethical issues. Only six studies discussed all three ethical issues. The subjects were mainly informed about the study purpose and procedure. There are limited discussions on how the subjects were informed about the risks involved in the study. Studies reported on how authors ensured confidentiality have also discussed anonymity in most cases. The results of the workshop discussion indicate that reporting ethical issues is important to improve the reliability of the research results. We propose a checklist based on the literature review, which we validated through a workshop.
Conclusion: The checklist proposed in this paper is a step towards enhancing ethical reporting in software engineering research.
Dienophilic reactivity of 2-phosphaindolizines: A conceptual DFT investigation
Authors: Beig Nosheen , Peswani Aarti , Bansal Raj Kumar 
Published: June 2022

The >C=P- or –N=P- functionality in 1,3-azaphospholo[1,5-a]pyridine, named as 2-phosphaindolizine and its 1- and 3-aza derivatives act as dienophiles and undergo Diels-Alder reaction with 1,3-dienes. However, the dienophilic reactivity is affected by the nature of the substituent groups on the two sides of the σ2,3-P atom and also by the presence of more nitrogen atom (s) in the five-membered ring. The conceptual density functional theory (DFT) calculations have been used in recent years to predict the reactivity of organic molecules in their reactions. We calculated global hardness (η), global softness (S), electronic chemical potential (μ), electrophilicity (ω) and nucleophilicity (N) indices of four classes of 2-phosphaindolizines, on the basis of which their observed relative dienophilic reactivities could be rationalized. Besides, the Fukui functions of the carbon/nitrogen and phosphorus atoms of the >C=P- and –N=P- functionalities were also computed which revealed their hard electrophilic character and accorded well with the dienophilic reactivities observed experimentally. Furthermore, energies and symmetries of the lowest unoccupied molecular orbitals (LUMO) of 2-phosphaindolizines were found to be in conformity with their dienophilic reactivities.

Purpose of the study. Analysis of the possibility of using presepsin in the early diagnosis of sepsis in cancer patients after extensive surgical interventions for tumors of the thoraco-abdominal localization.Materials and methods. The study included 27 people: 10 healthy individuals (control) and 17 patients who received surgical treatment at the National Medical Research Center of Oncology for malignant neoplasms of thoraco-abdominal localization. In the blood of all patients, studies of sepsis markers were performed: presepsin (P-SEP), highly sensitive CRP (hsCRP) (PATHFAST, Japan), procalcitonin (PCT), interleukin 6 (IL6) (Cobas e 411, Germany), as well as lactate, total leukocyte count (WBC) with a leukocyte formula, a blood culture test for suspected septic complications included in a routine examination. The studies were carried out before and on the 2nd day after the operation. Data were assessed by comparing P-SEP levels with hsCRP, PCT, IL6, lactate, WBC, blood culture test results, and the clinical status of patients. Depending on the data obtained, 2 groups were distinguished: I – patients with confirmed sepsis (3 people), II – without sepsis (14 people). Statistical processing was performed using STATISTICA 13.0.Results. In the control group, the level of P-SEP was 182.7 ± 11.9 pg/ml. In patients before surgery, the marker values were 213.7 ± 47.7 pg/ml, which did not differ statistically from the control data and did not go beyond the reference values, as did the content of PCT, hsCRP, IL6. On the 2nd day after surgery, all patients showed unidirectional changes, characterized by an increase in the levels of the studied parameters, but with varying degrees of intensity. The most significant was the increase in the concentration of presepsin. At the same time, it was noted that the level of presepsin on the 2nd day after surgery in patients of group I patients with confirmed sepsis averaged 2577.5 ± 1762.5 pg/ml with a maximum level 4340.0 pg/ml, and in group II with In the absence of confirmed bacteremia, there was an increase in the level of presepsin 1205.0 pg/ml. The data obtained correlated with the dynamics of changes in the concentration of other sepsis markers – hsCRP, PCT, IL6. Thus, the study of the level of presepsin, along with widely used markers – hsCRP, PCT, IL6, allows diagnosing sepsis in the early postoperative period in cancer patients.Conclusion. In patients with malignant neoplasms of thoracoabdominal localization, changes in the levels of sepsis markers in the early postoperative period can be used as a basis for prescribing antibiotic therapy. Presepsin may be recommended for use as an early marker of sepsis in patients with oncological pathology.

Published: June 2022

Abstract
Observations of the extragalactic (z = 0.0141) transient AT 2018cow established a new class of energetic explosions shocking a dense medium, producing luminous emission at millimeter and submillimeter wavelengths. Here we present detailed millimeter- through centimeter-wave observations of a similar transient, ZTF 20acigmel (AT 2020xnd), at z = 0.2433. Using observations from the NOrthern Extended Millimeter Array and the Very Large Array, we model the unusual millimeter and radio emission from AT 2020xnd under several different assumptions and ultimately favor synchrotron radiation from a thermal electron population (relativistic Maxwellian). The thermal electron model implies a fast but subrelativistic (v ≈ 0.3c) shock and a high ambient density (n

e
≈ 4 × 103 cm−3) at Δt ≈ 40 days. The X-ray luminosity of L

X
≈ 1043 erg s−1 exceeds simple predictions from the radio and UVOIR luminosity and likely has a separate physical origin, such as a central engine. Using the fact that month-long luminous (L

ν
≈ 2 × 1030 erg s−1 Hz−1 at 100 GHz) millimeter emission appears to be a generic feature of transients with fast (t
1/2 ≈ 3 days) and luminous (M
peak ≈ −21 mag) optical light curves, we estimate the rate at which transients like AT 2018cow and AT 2020xnd will be detected by future wide-field millimeter transient surveys such as CMB-S4 and conclude that energetic explosions in dense environments may represent a significant population of extragalactic transients in the 100 GHz sky.
Solar Polar Flux Redistribution Based on Observed Coronal Holes
Authors: Schonfeld Samuel J. , Henney Carl J. , Jones Shaela I. , Arge Charles N. 
Published: June 2022

Abstract
We explore the use of observed polar coronal holes (CHs) to constrain the flux distribution within the polar regions of global solar magnetic field maps in the absence of reliable quality polar field observations. Global magnetic maps, generated by the Air Force Data Assimilative Photospheric flux Transport (ADAPT) model, are modified to enforce field unipolarity thresholds both within and outside observed CH boundaries. The polar modified and unmodified maps are used to drive Wang–Sheeley–Arge (WSA) models of the corona and solar wind (SW). The WSA-predicted CHs are compared with the observations, and SW predictions at the WIND and Ulysses spacecraft are also used to provide context for the new polar modified maps. We find that modifications of the polar flux never worsen and typically improve both the CH and SW predictions. We also confirm the importance of the choice of the domain over which WSA generates the coronal magnetic field solution but find that solutions optimized for one location in the heliosphere can worsen predictions at other locations. Finally, we investigate the importance of low-latitude (i.e., active region) magnetic fields in setting the boundary of polar CHs, determining that they have at least as much impact as the polar fields themselves.
The Proper Motion of the Pulsar J1124–5916 in the Galactic Supernova Remnant G292.0+1.8
Authors: Long Xi , Patnaude Daniel J. , Plucinsky Paul P. , Gaetz Terrance J. 
Published: June 2022

Abstract
We present the first direct measurement of the proper motion of pulsar J1124–5916 in the young, oxygen-rich supernova remnant G292.0+1.8. Using deep Chandra ACIS-I observations from 2006 to 2016, we measure a positional change of 0.″21 ± 0.″05 over the ∼10 yr baseline, or ∼0.″02 yr−1. At a distance of 6.2 ± 0.9 kpc, this corresponds to a kick velocity in the plane of the sky of 612 ± 152 km s−1. We compare this direct measurement against the velocity inferred from estimates based on the center of mass of the ejecta. Additionally, we use this new proper-motion measurement to compare the motion of the neutron star to the center of expansion of the optically emitting ejecta. We derive an age estimate for the supernova remnant of ≳2000 yr. The high measured kick velocity is in line with recent studies of high proper motion neutron stars in other Galactic supernova remnants and consistent with a hydrodynamic origin to the neutron star kick.
Current view on the problem of treating fibrocystic breast disease in terms of herbal medicine
Authors: Sokolik Olena P. , Prozorova Galina O. 
Published: June 2022

Introduction: Fibrocystic breast disease, commonly called fibrocystic breasts or fibrocystic change, is a benign (noncancerous) condition, which is the most common pathology in women of reproductive age. Treatment of fibrocystic breast disease and concomitant pathologies can involve using herbs.
Materials and Methods: To make an analysis of literary sources on the development of fibrocystic breast disease in the pathogenesis of diseases of the female reproductive system (clinical human (75%) and animal studies (25%)) were published in the period of 2017–2021.
Results and discussion: The diversity of plants in the world is a promising ground for therapeutic improvisation, allowing for an individual approach to each patient, but, most importantly, creates possibilities for maneuvering in the event of ineffectiveness of any means. In some situations, herbal medicine is not only possible or permissible, but strictly mandatory, and is essentially the only effective therapeutic method, which is relatively safe provided the correct selection of combinations and control by a doctor who applies a certain method of phytotherapy, especially given a duration of treatment. The need for a deeper study is long overdue for the pharmacological capabilities of various plant raw materials in the treatment of not only this pathology, but others as well.
Conclusion: The development of phytotherapy should be based primarily on scientific developments, but this area can not be considered the prerogative of only phytotherapists, as herbal medicines should be in the arsenal of doctors of all specialties.
L’empereur d’Éthiopie et le roi des juifs. Circulation et interprétations d’un récit historique, VIe-XVe siècle
Authors: Weber Benjamin 
Published: June 2022

L’invasion du royaume juif de Himyar par le roi d’Axoum Kaleb en 525 apr. J.-C. fut un événement capital dont la mémoire s’est préservée dans de très nombreux textes, de langues et de natures très différentes. L’étude des différentes formes de cette mémoire historique permet de retracer le cheminement d’un de ces récits depuis la Syrie du VIe siècle jusqu’à l’Italie du XVe siècle, en passant par l’Éthiopie. Surtout, elle permet de mesurer à quel point un même récit peut être interprété de façons très différentes en fonction des époques, des sociétés et des contextes politiques. La diffusion d’un récit, à l’oral comme à l’écrit, ne relève donc pas d’une histoire strictement culturelle du contact entre les cultures : il s’agit d’un acte politique qui doit être analysé en prenant en compte les enjeux de pouvoir qui entourent sa transmission.
Comment susciter la motivation des élèves pour la grammaire ?
Authors: Gremion Sarah 
Published: June 2022

Ce livre propose une réflexion sur l’enseignement d’un sujet réputé difficile et impopulaire : la grammaire.
Comment motiver les élèves en grammaire et comment mettre en œuvre des démarches d’enseignement engageantes ?
Pour tester, dans sa pratique, des outils pour susciter la motivation des élèves, Sarah Gremion travaille avec des élèves de 10–11 ans sur la notion d’attribut du sujet.
Le livre propose une description précise des démarches d’enseignement mises en place, à partir desquelles tout enseignant ou stagiaire pourra se projeter dans son propre contexte de classe.
Optant pour un enseignement de la grammaire dosant induction et déduction, l’autrice encourage à expérimenter et à s’adapter, se documenter et oser.
De ce travail de terrain, l’autrice dégage cinq principes qui aideront les nouveaux enseignants à planifier des séquences didactiques en grammaire ; et qui aideront les élèves à entrer dans l’apprentissage, pour comprendre à quoi sert la grammaire.
Les enquêtes PISA dans les systèmes scolaires valaisan et genevois
Authors: Revaz Sonia 
Published: June 2022

L’utilisation des enquêtes PISA comme outil de régulation des poli­tiques éducatives suscite débats et controverses sur la scène scolaire internationale. Tous les trois ans, PISA évalue les compétences des élèves au terme de leur scolarité obligatoire puis compare les résultats des pays participants dans le but de tirer des conclusions sur leurs sys­tèmes éducatifs et d’identifier d’éventuels facteurs de succès. L’enjeu est de déterminer dans quelle mesure les élèves disposent des connais­sances et des outils nécessaires à leur insertion dans la société moderne et au développement de celle-ci.
Suivant le même principe, la Suisse s’est soumise à une enquête PISA supplémentaire à l’échelle nationale afin de disposer de données plus approfondies sur chacun de ses cantons. Nous nous intéresserons à la Suisse romande, où la revendication de l’objectif de promotion de mo­dèles efficaces et équitables peine à faire l’unanimité. Qu’en est-il des cantons du Valais et de Genève en particulier, où les résultats des élèves apparaissent très contrastés ?
Cet ouvrage propose une analyse des quatre premières enquêtes PISA dans ces deux cantons afin de déterminer d’où proviennent ces diffé­rences de performance, d’identifier les raisons qui expliquent le scepti­cisme existant au sujet de PISA et d’établir d’éventuelles relations entre les résultats PISA et certaines mesures appliquées au plan des politiques éducatives régionales et cantonales.
Dynamique climatique et dégradation des terres agricoles autour des petits lacs du plateau de Zagnanado au Bénin
Authors: Etene Cyr Gervais 
Published: June 2022

Les perturbations climatiques observées ces dernières décennies ne demeurent pas sans conséquences sur les terres agricoles de même que les ressources en eaux. Au Bénin, les différentes crises climatiques (sécheresse, inondations, etc.) poussent les populations à occuper les berges des cours d’eau pour des activités agricoles. La présente recherche vise à analyser les effets de la dynamique climatique sur les terres agricole autour des petits lacs du plateau d’Abomey-Zagnanado au Bénin. Pour apprécier les effets des perturbations climatiques autour de ces petits lacs, les données climatologiques et cartographiques ont été collectées. La statistique descriptive a été mise à contribution de même que l’étude de l’occupation des terres a permis d’apprécier les effets du climat sur les terres agricoles. Il résulte de cette recherche que la chronique des précipitations annuelles (1952-2018), on montre que le secteur d’étude est caractérisé par une succession des périodes humides (47 %) et sèches (53 %). La tendance de la température moyenne annuelle est à la hausse de 26,35 à 28,75 °C entre 1952 et 2018 ; soit une augmentation de 1,1 °C sur la période d’étude. Le déficit pluviométrique lié à la fréquence des années sèches, a entraîné l’accentuation des pressions humaines sur les écosystèmes des zones humides, l’aggravation des phénomènes érosifs. L’analyse de la dynamique de l’occupation des terres entre 2005 et 2018 a montré que cette dynamique est marquée par la régression de toutes les formations végétales naturelles (savane boisée et arbustives et forêt galerie) au profit des unités d’occupation anthropiques (mosaïque de cultures et jachères (24,04 %), plantation (0,30 %), agglomération (1,65 %)). En 2019 sur un versant, il est enregistré 15,26 cm de terre érodée contre 12 cm en 2018.Cette dégradation qui ne demeure pas sans conséquences sur les terres agricoles.
Les étangs et leurs ressources piscicoles : perceptions, pratiques et consommations des français – Résultats d’une enquête extrapolée au niveau national
Authors: Garcia Romain , Choffel Quentin , Nasser Tarek 
Published: June 2022

Les étangs sont au cœur de nombreuses problématiques des territoires de l’eau : sociétales, aménagement du territoire, écologiques, économiques… La prise en compte des perceptions de la population vis-à-vis de ces plans d’eau est inexistante dans les différentes politiques de gestion et de développement des territoires de l’eau. Réservoirs de biodiversité, ils souffrent de leur origine anthropique dans une vision centrée sur la nature et ne sont pas pris en compte dans les politiques de gestion de l’eau. L’objet de cette étude exploratoire est d’apporter des premiers éléments de réflexions et de réponses quant aux perceptions du grand public sur les étangs, que ce soit au niveau patrimonial, culturel, naturel ou fonctionnel. La réalisation et la diffusion d’un questionnaire ont permis de collecter des résultats variés sur les perceptions, mais aussi sur les liens qu’entretiennent les enquêtés avec ce milieu (pratique de loisirs, consommation de poisson d’eau douce). Cette étude exploratoire permet d’avancer certains résultats qui mériteront d’être affinés, notamment pour orienter et faciliter la gestion des étangs (par exemple, via une prise en compte de la perception du public, des acteurs / gestionnaires, des élus). L’étude montre une appréciation et une vision naturelles de l’étang pour plus de 500 personnes interrogées. Cette vision va à l’encontre de celle menée par les politiques publiques depuis quelques années. première validation de la clef de gestion.
