Published: June 2022

<p> Physics informed neural networks (PINNs) have been a well-known tool in solving forward and inverse partial differential equations (PDEs) problem. In particular, for the forward problem, only the initial/boundary conditions and the equation itself as the physical information are needed to obtain the predicted solution within the definition domain. However, some existing works show that the standard PINN method is insufficient for solving complex problems. For the relatively complex one-dimensional Euler equation problem, due to the limited accuracy of the standard PINN method, the algorithm is improved in two aspects in this study. First, a gradient-related weight function is introduced into the loss function and the framework of gradient-weighted physics-informed neural networks (gwPINNs) is proposed. In particular, the weight function is carefully designed. Second, the sequence-to-sequence (seq2seq) learning is applied in the training process to improve the precision. Then, four cases of Riemann problems are solved using the improved algorithm. The results show that the improved algorithm can obtain high accuracy in solving these problems, and verify the feasibility of solving one-dimensional Euler equation based on the improved PINN method.</p>

Empirical AI Transformation Research: A Systematic Mapping Study and Future Agenda
Authors: Peretz-Andersson Einav , Torkar Richard 
Published: June 2022

Background: Intelligent software is a significant societal change agent. Recent research indicates that organizations must change to reap the full benefits of AI. We refer to this change as AI transformation (AIT). The key challenge is to determine how to change and which are the consequences of increased AI use.
Aim: The aim of this study is to aggregate the body of knowledge on AIT research.
Method: We perform an systematic mapping study (SMS) and follow Kitchenham’s procedure. We identify 52 studies from Scopus, IEEE, and Science Direct (2010–2020). We use the Mixed-Methods Appraisal Tool (MMAT) to critically assess empirical work.
Results: Work on AIT is mainly qualitative and originates from various disciplines. We are unable to identify any useful definition of AIT. To our knowledge, this is the first SMS that focuses on empirical AIT research. Only a few empirical studies were found in the sample we identified.
Conclusions: We define AIT and propose a research agenda. Despite the popularity and attention related to AI and its effects on organizations, our study reveals that a significant amount of publications on the topic lack proper methodology or empirical data.

Malignant tumors of the head and neck are still one of the most challenging problems of treatment in modern oncology. The disease affects mainly the capable people (from 30 to 60 years old). Tumor lesions of the paranasal sinuses lead to disability and have a high mortality rate. Head and neck tumors comprise of 20–30 % of all cancer cases. People with early paranasal sinus cancer have minor complaints, their general condition doesn’t get affected so they don’t seek for medical care in a while. As a result, patients start on treatment at tumor grades III–IV. This article provides the most complete information about the causes, frequency and special features of the course of paranasal sinus cancer, as well as about modern methods of it’s diagnosis and combination treatment. Despite the great advances in the treatment of these malignant tumors the three and five year survival rates remain unsatisfactory, which requires a research for new effective treatments. Currently the main treatment methods for these malignant tumors are combination and complex (involving surgery, radiotherapy and chemotherapy) treatments. The standard treatment approach includes radical surgical removal of the primary tumor and metastatic lymph nodes followed by radiation or chemoradiation therapy. Chemotherapy as monotherapy is administered in non-resectable primary or recurrent tumors, distant metastases or when a patient refuses the radical surgery. Improvement of existing treatment methods and development of new ones are an essential need. Earlier detection of the disease requires primary care physicians to be trained to diagnose tumor lesions of the paranasal sinuses, and highly specialized physicians (dentists, otorhinolaryngologists, maxillofacial surgeons, dermatologists) to express their cancer alertness.
Discrepancy between the Low-frequency Cutoffs of Type III Radio Bursts Based on Simultaneous Observations by WIND and PSP

Abstract
The cutoff frequency is an important characteristic parameter of type III radio bursts. Employing the radio data of the Parker Solar Probe (PSP) in the encounter phases of its first five orbits, our previous work revealed that the maximum probability distribution of the cutoff frequency f

lo
(∼680 kHz) is remarkably higher than that based on Ulysses and WIND (∼100 kHz) investigated by Leblanc et al. and Dulk et al. However, the main influencing factor of the discrepancy is still unknown though the possible reasons are discussed. In this study, we utilize the simultaneous observation by WIND and PSP to analyze statistically the distribution of the cutoff frequency of type III radio bursts, which had not been done before. Based on the automatic Canny edge detection and manual selection, we obtain the f

lo
of 491 (WIND) and 1194 (PSP) type III bursts from their simultaneous observations in the same solar activity period (from 2019 January 1 to 2020 July 31). The statistical results show that the dominant cutoff frequency measured by PSP (i.e., ∼700 kHz) is still significantly higher than that by WIND (i.e., ∼100 kHz). This implies that radiation attenuation is the main influencing factor for the difference in the statistical results of the cutoff frequency.

Abstract
A radio-emitting tidal disruption event (AT2019dsg) is proposed as a likely counterpart to the IceCube neutrino event IC 191001A. In this work, we have revisited the Fermi-LAT data in the direction of the neutrino and confirmed no signal at the site of AT2019dsg. Instead, at the edge of the 90% confidence level error region of this neutrino, there is a γ-ray transient source associated with the blazar GB6 J2113+1121. In 2019 May, GB6 J2113+1121 was undergoing a γ-ray flare that is unprecedented since the start of the Fermi-LAT operation, with a variability amplitude of about 20 fold. Similar violent flares of GB6 J2113+1121, unobserved before, have also been detected in the optical bands. Moreover, the blazar remained in a high-flux state in the infrared bands when IC 191001A arrived, though the blazar ‘s γ-ray and optical activities have temporarily ceased. Motivated by this spatial and temporal coincidence, we suggest that GB6 J2113+1121 is a candidate to be the counterpart to IC 191001A. The jet properties of GB6 J2113+1121 are investigated, which are found to be comparable with that of neutrino-emitting blazars (candidates). A specific analysis of archival IceCube data in this direction and future observations would put further constraints on the origin of the neutrino.

Published: June 2022

INTRODUCTION: Pile excision is frequently associated with post-operative pain and prolonged hospital stay. A modern technique performed with LigaSure (LS) seems to be especially efficient when large pile tissue removal is needed.

AIM: The research compares LS pile excision with diathermy for the treatment of III-IV degree pile.

PATIENTS AND METHODS: Two hundred and eight patients with pile III or IV degrees randomized into two groups: Group one LS and group two diathermy. The study evaluates the mean post-operative time, post-operative pain, discharge date, and time return to usual works early and late complication. All patients followed up for a range (12–24) months.

RESULTS: One hundred and eight patients managed by diathermy, 100 managed by LS. The operating time is considerably shortened in LS; post-operative pain disappears earlier in LS than diathermy. In addition, the timely return to work reduces in LS, while no distinction between hospitalization and post-operative complications.

CONCLUSIONS: LS is an efficient procedure in degree III or VI pile excision. Therefore, the procedure enhances to use LS as the treatment of choice for Classes III–IV pile, even it is more expensive than diathermy operation.

Абстрактный Цель исследования: оценить роль спекл-трекинговой эхокардиографии в выявлении ранней дисфункции миокарда у женщин с артериальной гипертензией в перименопаузальном периоде. Материал и методы. В исследовании приняли участие 50 женщин перименопаузального периода в возрасте от 45 до 55 лет. Перименопауза диагностировалась на основании клинического осмотра, включающего осмотр у гинеколога и исследования гормонального статуса женщины. Выборка женщин была разделена на две группы в зависимости от наличия артериальной гипертензии. В основную группу вошли 24 пациентки с артериальной гипертензией, диагностированной в перименопаузальном периоде. Перечисленные выше методы обследования также включали электрокардиографию, эхокардиографию и спекл-трекинговую эхокардиографию. Результаты. По данным спекл-трекинговой эхокардиографии выявлены статистически значимые показатели в базально-антеропостероидном и нижнебазальном сегментах (р = 0,016; 0,001). Разница индекса массы миокарда левого желудочка была статистически значимой в сравниваемых группах (р = 0,038). ROC-анализ использовался для оценки качества полученной модели логистической регрессии. Площадь под ROC-кривой составила 0,806 ± 0,065 (95% ДИ: 0,679–0,933, p <0,001). Это указывает на «очень хорошее» прогностическое качество модели. Заключение: в группе больных с артериальной гипертензией более чувствительны показатели базального переднеперегородочного и базально-нижнего сегментов, что может быть использовано как значимый показатель дисфункции при неизменных показателях стандартной эхокардиографии.
Le Constitutum Constantini et l’impérialisation de l’église romaine
Authors: Ioan Mureşan Dan 
Published: June 2022

La présente étude se propose de contribuer à la question de l’impérialisation de l’Église romaine à travers une analyse à nouveaux frais du contenu idéologique du Constitutum Constantini, document que E. Kantorowicz plaçait à l’origine de ce processus historique. Un panorama de l’historiographie consacrée au Constitutum Constantini permet de dégager six modèles interprétatifs en concurrence qui situent la genèse du document entre 750 et 850. Sans pour autant en ajouter un septième, cet article propose une relecture du document comme un type spécial d’acte performatif, qui historicise un modèle ecclésiologique sous l’apparence d’un document juridique impérial. Tout en reconnaissant ainsi les structures narratives qu’il contient, cela permet d’avancer que le Constitutum Constantini reste, malgré les affirmations contraires, un manifeste théologico-politique de réelle importance.
Il est fondé sur une économie de la gloire qui relie sa conception trinitaire à la potestas et dicio de l’évêque de Rome. Le document s’organise autour du concept central de summus pontifex et papa universalis, qui renverse la domination religieuse des prêtres du Capitole (identifiés avec les flamines maiores, et surtout le flamine de Jupiter) et se voit attribuer pour cela de la part de l’empereur Constantin (i.e. le pontifex maximus), nouvellement baptisé, la dimension religieuse de son autorité, symbolisée par le pontificalis apex. C’est donc ce transfert politico-religieux qui fonde essentiellement l’imitatio imperii, thème crucial que l’auteur du Constitutum emprunte à Cassiodore. Ce constat permet enfin de faire ressortir l’importance de l’idée de papa universalis, avancée par l’auteur anonyme en désaccord implicite avec l’interdit formel par le pape Grégoire le Grand de ce titre dans la pratique pontificale. Il en ressort que l’impérialisation de la papauté s’opère concomitamment avec la pontificalisation et l’universalisation de l’Église romaine.
Anselm of Havelberg as ‘ecumenist’: fiction and history
Authors: Avvakumov Yuri P. 
Published: June 2022

The essay examines one of the most intriguing texts of the history of Latin-Greek encounter in the twelfth century, Anticimenon by Anselm of Havelberg. Even after the appearance of a few important studies on Anselm in recent decades, this German courtier bishop, canon regular, and theologian remains a widely-misread author. The lack of continuity in research is here particularly confusing. Despite the discovery of the non-historicity of Anticimenon made by Sieben in the 1980s, Anselm’s text is still too often read as a historical account of a real Latin-Byzantine debate. The essay builds up on Sieben’s discovery and explores the topic of the Eucharistic water in Anselm’s work which not only confirms earlier conclusions but also brings them to a new level. The author argues that the non-historicity of the Anticimenon deprives it of its status of a primary source in respect to Byzantine theology. At the same time, the study of the fictitious character of Anselm’s work makes it possible to gain new insights into the Latin theology of the mid-twelfth century. The topic of the Eucharistic water demonstrates that even such minute problem could promote discussion on issues of fundamental importance. The topics related to Eastern Christianity function in the Anticimenon as illustrations of the main concern of the entire work —the unity of faith in the plurality of ecclesiastical traditions and sacramental rites.

La caldera du Torfajökull et sa diversité géomorphologique (Islande)
Authors: Bussard Jonathan 
Published: June 2022

La diversité géomorphologique exceptionnelle de la caldera du Torfajökull est le résultat de l’activité de plusieurs processus : le volcanisme, la géothermie, la gélifraction, l’érosion glaciaire et l’érosion fluviale, ainsi que la combinaison entre plusieurs de ces processus. Les affleurements de rhyolites et leur érosion venant alimenter un vaste sandur aux couleurs claires contrastent avec la coulée de lave noire d’obsidienne, la Laugahraun, qui date de l’an 1477. Afin de protéger les formes géothermales, la caldera est protégée depuis 1979, mais la récente augmentation de la fréquentation touristique accentue la pression humaine sur ces sites fragiles.
Enquêter sur la reconnaissance des sensibilités athées en Turquie contemporaine
Authors: Malçok Théo 
Published: June 2022

Souvent réduite à une fonction d’indicateur de l’évolution des religiosités, la présence de l’athéisme dans la société turque a rarement fait l’objet d’études détaillant les modalités concrètes de ses manifestations. Le présent article propose de relever ce défi en partant du constat que la variation du degré d’exposition des sensibilités athées est façonnée par une dynamique séculaire opposant la continuité d’un déni à des tentatives de reconnaissance des exclus de l’assignation confessionnelle majoritaire. En s’appuyant sur l’armature théorique des figures sociologiques de la reconnaissance (objective, de soi, mutuelle), trois logiques sociales sont identifiées à partir d’une enquête de terrain auprès d’un éventail d’individus : sceptiques, incroyants, athées à-peu-près… La première logique est l’issue, toujours incertaine, de l’épreuve du regard normatif : situation problématique, qui peut se répéter quotidiennement, du soupçon ou de l’accusation d’apostasie, contournés, négociés ou confrontés. Les signes extérieurs des sensibilités athées sont donc labiles dans la mesure où ils se dé-jouent dans la performance de soi. Dans un deuxième mouvement biographique, la découverte ex post facto des signes intérieurs d’une sensibilité athée se réalise sur fond d’une prise de conscience d’un illettrisme religieux pour certains, attribut de classe les distinguant de la masse des croyants, ou dans le clivage qu’induit une mobilité sociale fantasmée ou effectuée, pour une partie de l’échantillon issue d’un milieu pieux. L’amplitude d’une reconnaissance mutuelle basée sur le dénominateur commun d’une sensibilité athée sera analysée dans un troisième temps comme dépendant largement des aspirations d’un mouvement associatif émergent. Porté notamment par l’Association de l’Athéisme (Ateizm Derneği), fondée en 2014, ce mouvement transforme un sentiment d’ostracisation, c’est-à-dire de déni de reconnaissance, ressenti par une partie des sans-Dieu et des sans religion, en motif de lutte. Malgré les moyens matériels, humains et symboliques mis en place, l’association semble condamnée à la marginalité dans la mesure où ses potentiels adhérents bénéficient de réseaux de resocialisation concurrents.
Oligometastatic breast cancer

Published: June 2022

Introduction:
Oligometastatic represents a distinctive subset of metastatic breast cancer (MBC). Incidence has been reported, in 1–5% of all newly diagnosed MBC. Literature is very sparse, especially from India.

Material and Methods:
We have ambispectively screened 500 patients of upfront female MBC between the period of January 2013 and August 2018 at Institute Rotary Cancer Hospital, All India Institute of Medical Sciences, New Delhi and 120 patients of oligometastatic breast cancer (OMBC) were included for analysis. Clinical, pathological, receptor status (ER estrogen receptor, PR progesterone receptor, and HER2/neu human epidermal growth factor), radiological, treatment, and survival details were recorded.

Results:
The median age of presentation was 50 (range 22–78) years. One organ was involved in 96 (80%) patients, and two organs were involved in 36 (20%) patients. ER and/or PR was positive in 48 (40.0%), ER/PR, and HER2/neu were positive in 28 (23.3%) cases. Only HER2/neu was positive in 21 (17.5%), and triple negativity was seen in 23 (19.2%) patients. Ninety-four (78.3%) patients received neoadjuvant therapy, and 12 (10%) patients underwent conservative breast surgery. The overall response rate at the metastatic site was 74.1%, and a complete response was seen in 42.5% of patients. Median progression-free survival (PFS) for the cohort was 25.43 months. The estimated PFS at 2 years and, at 5 years, was 54.6% and 21.6%, respectively. The hormone receptor positivity, bone metastasis, and patients with surgery after neoadjuvant chemotherapy (NACT) had a statistically significant better PFS on multivariate analysis. In a subset analysis of HER2/neu receptor-positive patients, who received targeted therapy showed better PFS compared to those who did not receive.

Conclusion:
The incidence of OMBC is 24% of the total MBC. The patients with OMBC who have hormone receptor-positive, bone-only metastasis, and surgery after NACT show a better outcome.
