P.Ross. Georg. I 21: riedizione e commento del più esteso manuale di ieroscopia
Authors: Costanza Salvatore , Papathomas Amphilochios 
Published: August 2021

Abstract
Greek papyri dating between the 2nd and the 4th centuries AD bear testimony to treatises about hieroscopy, the study of animal entrails, especially the liver, for the purpose of divination. The present article is dedicated to the best preserved handbook on this divinatory technique, P.Ross. Georg. I 21, which provides detailed instructions on how to “read” the entrails. A new critical edition of the papyrus is presented with translation and commentary.
The Monastery of Apa Posidonios at Hermonthis and an Alleged Local Cult of “Poseidon” (with Notes on “Kothos” and the Supposed Fish-Cult at Latopolis)
Authors: Krueger Frederic 
Published: August 2021

Abstract
This article compiles the available information regarding the Monastery of Apa Posidonios at Hermonthis and explores the possibility that its patron saint may have been the Egyptian anchorite, Posidonios, mentioned in the Lausiac History. The assessment of a Hermonthite cult of “Poseidon” described in a Coptic encomium leads into a general discussion of hagiographical constructions of “pagan” cults.
A Note on the Existence of the Competitive Equilibrium in Grossman and Shapiro (1984)
Authors: Creane Anthony 
Published: August 2021

Abstract
In their seminal paper, Grossman, G. M., and C. Shapiro. 1984. “Informative Advertising with Differentiated Products.” The Review of Economic Studies 51: 63–81 assume that it is not profitable for a firm to deviate to the supercompetitive price of Salop, S. C. 1979. “Monopolistic Competition with outside Goods.” The Bell Journal of Economics 10: 141–56. In this note, it is shown that this assumption is violated if, roughly, each firm reaches less than half of all consumers unless it is a duopoly. This implies that most of the simulations in Grossman, G. M., and C. Shapiro. 1984. “Informative Advertising with Differentiated Products.” The Review of Economic Studies 51: 63–81 are not actually equilibria. More importantly, this implies that for their equilibrium to exist nearly all consumers must receive at least one ad. For example, with just four firms in the market, at least 96% of the consumers must receive at least one ad, and this percentage increases with the number of firms in the market.
Tracking heart surface features to determine myocardial contrast agent enrichment
Authors: Sprenger J. , Petersen J. , Neumann N. , Reichenspurner H. , Russ D. , Detter C. , Schlaefer A. 
Published: August 2021

Abstract
Fluorescent cardiac imaging can be applied for intraoperative quality control after a coronary bypass grafting surgery to ensure the myocardial perfusion by evaluating the increasing contrast agent enrichment in the heart. The motion due to the beating heart impedes the interpretation of the contrast agent enrichment in the vessels and leads to noisy enrichment curves. We propose tracking of the heart surface features to compensate for the motion of the beating heart and thereby improve the analysis of the contrast agent enrichment. Furthermore, we propose a vessel segmentation pipeline for a local evaluation of contrast agent enrichment directly in the vessels.

Published: August 2021

Abstract
Background and objectives: Both hepatic functional reserve and the underlying histology are important determinants in the preoperative risk evaluation before major hepatectomies. In this project we developed a new approach that implements cutting-edge research in machine learning and nevertheless is cheap and easily applicable in a routine clinical setting is needed. Methods: After splitting the study population into a training and test set we trained a convolutional neural network to predict the liver function as determined by hepatobiliary mebrofenin scintigraphy and single photon emission computer tomography (SPECT) imaging. Results: We developed a workflow for predicting liver function from routine CT imaging data using convolutional neural networks. We also evaluated in how far transfer learning and data augmentation can help to solve remaining manual data pre-processing steps and implemented the developed workflow in a clinical routine setting. Conclusion: We propose a robust semiautomatic end-to-end classification workflow for abdominal CT scans for the prediction of liver function based on a deep convolutional neural network model that shows reliable and accurate results even with limited computational resources.

Аннотация
История славистики складывается как из истории различных идей, концепций и научных организаций, так и из судеб отдельных ученых, на которые влияют не только состояние названной области науки, но и жизнь общества в целом. Публикуемый труд относится к области историко-антропологических исследований и проведен с позиций «новой биографической истории» или «персональной истории», особенно плодотворных при изучении судьбы ученых, в данном случае известного слависта, и предполагающих повышенное внимание к культурно-историческому контексту эпохи. Анализ архивных документов позволяет реконструировать обстоятельства жизненного и научного пути ученого, проследить причины научной командировки Н.Н. Дурново за границу, которую он использовал для чтения лекций в университете Брно, работы в библиотеках в Праге, организации и участия в диалектологических экспедициях с целью изучения диалектов Карпатской Руси. Важным научным результатом Дурново стала подготовка и издание в Чехословакии его книги «Введение в историю русского языка», получившей высокую оценку его зарубежных и отечественных коллег и не утратившей своей актуальности для современной лингвистики.

Local limit theorems for generalized scheme of allocation of particles into ordered cells
Authors: Timashev Aleksandr N. 
Published: August 2021

Abstract
A generalized scheme of allocation of n particles into ordered cells (components). Some statements containing sufficient conditions for the weak convergence of the number of components with given cardinality and of the total number of components to the negative binomial distribution as n → ∞ are presented as hypotheses. Examples supporting the validity of these statements in particular cases are considered. For some examples we prove local limit theorems for the total number of components which partially generalize known results on the convergence of this distribution to the normal law.

Abstract
In this research work nanoparticles of Mg (0, 1, 2 and 3%) doped MoS2 are prepared by Hydrothermal method at 200 °C for 9 h. Scanning Electron Microscope (SEM) for surface morphology, Fourier Transform Infrared Spectroscopy (FTIR) for structural and chemical bonding and UV-visible spectroscopy for optical properties are used. SEM showed that sheet-like structure has changed into stone-like shaped when Mg has doped into MoS2. From FTIR, Mo–O, Mo=S, and H–O bond peaks are becoming dim and new chemical bonds S=O, Mo=O, Mg–O, CH and OH are forming with the increase of Mg doping. UV-visible spectroscopy showed that MoS2 has an indirect bandgap 2.21 eV. Band gap decreased from 1.84 to 1.82 eV when the Mg doping was increased from 1 to 2%, respectively. As Mg concentration was increased i.e. 3% then band gap increased to 1.88 eV. Photocatalytic activity (PCA) of undoped and Mg doped MoS2 is appraised by degrading rhodamine blue (RhB) and methylene blue (MB) dyes. The results showed that PCA (in presence of visible light) Mg doped MoS2 is greater than pure MoS2 which significantly increased the photocatalytic properties.

Published: August 2021

Background:
To evaluate the mechanical and surface properties of two glass ionomer
restorative systems (EQUIA Fil, Ionostar Molar) and a resin composite (Charisma
Classic ) after thermocycling. Methods:
Twenty disk-shaped samples were prepared from each material in teflon molds
according to manufacturer’s instructions. After the samples were stored in
distilled water at 37 0C for 24 h, microhardness and surface
roughness measurements were performed from each group and repeated after 5000
and 10000 thermocycling. Scanning electron microscopy examinations were also
performed. The data were analyzed by using Wilcoxon signed rank and Bonferroni
corrected multiple comparison tests.Results: EQUIA
did not exhibit significant differences in its micohardness values after
thermocycling (p &gt; 0.0056). In contrast, Ionostar Molar and
Charisma Classic exhibited statistically significant decreases in baseline
microhardness after 5000 and 10000 thermocycling processes (each p &lt;
0.0056). However, there were no significant differences between 5000 and 10000
thermocycling groups for Charisma Classic (p = 0.007).
Ionostar Molar exhibited no statistically significant differences between its
surface roughness values before and after thermocycling groups (p &gt; 0.0017). Similarly, there were no significant
differences between baseline and 5000 thermocycling groups for EQUIA and
Charisma Classic (p &gt; 0.0017). However, a
statistically significant increase was observed after 10000 thermocycles for
both of these two materials (p &lt; 0.001 and p = 0.002, respectively).Conclusion: The
EQUIA and Ionostar Molar exhibited mechanical features similar to those of a
resin composite, and thus, represent promising materials for permanent
restorations.

OBJECTIVES
Ensuring high coronavirus disease-2019 (COVID-19) vaccine uptake among US child care providers is crucial to mitigating the public health implications of child-staff and staff-child transmission of severe acute respiratory syndrome coronavirus 2; however, the vaccination rate among this group was previously unknown.

METHODS
To characterize vaccine uptake among US child care providers, we conducted a multistate cross-sectional survey of the child care workforce. Providers were identified through various national databases and state registries. A link to the survey was sent via e-mail between May 26 and June 23, 2021. A 37.8% response yielded 21 663 respondents, with 20 013 satisfying inclusion criteria.

RESULTS
Overall COVID-19 vaccine uptake among US child care providers (78.2%, 90% confidence interval: 77.5% to 78.9%) was higher than the US general adult population (65%). Vaccination rates varied between states from 53.5% to 89.4%. Vaccine uptake among respondents differed significantly (P &lt; .01) based on respondent age (70.0% for ages 25–34, 91.6% for ages 75–84), race (70.0% for Black or African Americans, 92.5% for Asian Americans), annual household income (70.8% for &lt;$35 000, 85.1% for &gt;$75 000), and child care setting (73.0% for home-based, 79.7% for center-based).

CONCLUSIONS
COVID-19 vaccine uptake among US child care providers was higher than the general US adult population. Those who were younger, lower income, Black or African American, resided in states either in the Mountain West or the South, and/or worked in home-based child care programs reported the lowest rates of vaccination. State public health leaders and lawmakers should prioritize these subgroups to realize the largest gains in vaccine uptake among providers.
Rola trenera w przygotowaniu współczesnej młodzieży do profesjonalnego uprawiania piłki nożnej.
Authors: Koprukowiak Grzegorz 
Published: August 2021

We współczesnym społeczeństwie dochodzi do pogłębiających się zmian w sposobie funkcjonowania w różnych przestrzeniach życiowych, których źródłem jest postępujący rozwój cywilizacyjny, wpływający na charakter i specyfikę pokoleń. Wśród przestrzeni w których owe zmiany są zauważalne, można wyróżnić współczesny charakter pracy zarobkowej, uwarunkowanej przemianami cywilizacyjnymi i gospodarczymi, co w dalszej kolejności przekłada się także na aspekt życia osobistego. W świetle tych przemian, zupełnie nowe znaczenie zyskuje aspekt uczestnictwa w kulturze fizycznej, które obecnie staje się głównie jednym ze sposobów aktywnego wypoczynku dla osób dorosłych. Obok dużej grupy społeczeństwa praktykującej w ramach spędzania wolnego czasu jej różne formy, wyróżnić można grupę dzieci i młodzieży, wśród której sport staje się formą dążenia do marzeń o przyszłej karierze zawodniczej na miarę swoich piłkarskich autorytetów z światowej czołówki. Aspiracje te stanowią długą ścieżkę, w której młody zawodnik obok doskonalenia swoich umiejętności sportowych, uczestniczy w procesie selekcji pozwalającej na wyróżnienie spośród zawodników, szczególnie utalentowanych jednostek, posiadających wyjątkowe predyspozycje do profesjonalnego uprawiania sportu. Proces kształcenia umiejętności sportowych młodego zawodnika, jest równocześnie procesem pedagogicznym w którym szczególną misję posiada trener. Dlatego też celem badań jest zaprezentowanie jego roli w procesie wychowawczym.
Niniejsze rozważania, oparte zostały o przegląd dostępnej literatury naukowej z zakresu pedagogiki, psychologii i socjologii kultury fizycznej, z wykorzystaniem dorobku naukowego z zakresu teorii sportu. Rozważania przebiegają w kluczu zaprezentowania tła społecznego charakterystycznego dla obecnych czasów, w które wpisuje specyfika zawodu profesjonalnego gracza piłki nożnej i wyzwania stojące przed środowiskiem, mające na celu właściwe przygotowanie do profesjonalnego sportu. Kolejnym punktem zawartym w publikacji, będzie zaprezentowanie procesu dojrzewania młodego gracza do zawodowego uprawiania dyscypliny.
W świetle omówionych zagadnień nastąpi wyraźne zauważenie roli współczesnego trenera jako wychowawcy, mentora i opiekuna na drodze wzrastania ku karierze, ale także ku wypracowaniu dobrych postaw u młodego zawodnika jako osoby.
Zaprezentowane badania prowadzą ku wnioskowi dowodzącemu, że kompetencje współczesnego trenera znacząco wykraczają poza samą funkcję czysto sportową. Trener poza kompetencjami ściśle związanymi z pracą na boisku, powinien wykazywać się szeregiem kompetencji miękkich – znajomością podstaw pedagogiki, psychologii, socjologii, które umożliwią mu lepsze zrozumienie środowiska swoich podopiecznych. W ich wyniku staje się możliwe budowanie postawy lidera, autorytetu i kształtowania odpowiednich postaw u młodych zawodników.
SPOŁECZNE ZAKORZENIENIE ARCHITEKTURY NA PRZYKŁADZIE XVII-WIECZNEJ SYNAGOGI W ZAMOŚCIU
Authors: Morawska Wiktoria 
Published: August 2021

ABSTRAKT
Teza. Celem artykułu jest wskazanie społecznego zakorzenienia architektury synagogalnej na przykładzie XVII-wiecznej bóżnicy w Zamościu. Analiza stanowi próbę wykazania związku między usytuowaniem zabytku w strukturze urbanistycznej a przeżyciami mniejszości, historią losów społeczności i gminy żydowskiej na terenie miasta.
Omówione koncepcje. Z uwagi na charakter podjętego tematu analiza była oparta na badaniach archiwaliów, co stanowi podstawową metodę pracy w ramach dyscypliny historii sztuki. Oprócz studiów materiałów inwentaryzatorskich i samego obiektu w treści artykułu odnoszono się do tez najważniejszych badaczy i badaczek architektury synagogalnej i urbanistyki w Polsce: E. Bergman, J. Jagielskiego, A. Łupienko, A. Zabłockiej-Kos, K. Matyjaszka, M. oraz K. Piechotków.
Wyniki i wnioski. Analiza wykazała błędność dotychczasowych interpretacji stylistyki synagogi w Zamościu jako sefardyjskiej. Wysuwa się wniosek, że wzorem była – oprócz wcześniejszych bożnic, w których stosowano centralizację głównej sali modlitewnej i podobny układ – architektura kościelna z obszaru Ordynacji Zamojskiej. Świadczy o tym m.in. implikowanie detalu stosowanego w ramach typu kalisko-lubelskiego. Wątek ten wysuwa się także jako nowy problem badawczy, który, jak do tej pory, nie został opisany w kontekście budownictwa judaizmu.
Jednocześnie wskazuje się na szeroki kontekst społeczny, w którym istnieje przedreformacyjna architektura synagogalna. Przełom XVI i XVII w. był czasem kreowania nowych form w obrębie budownictwa żydowskiego w Polsce i tzw. Złotym Wiekiem Żydów Polskich. Jest to odwrotną tendencją od krajów Europy Zachodniej, z których wysiedlono społeczność żydowską, a rozwój budowlany został wstrzymany.
Wartość poznawcza podejścia. Największą wartość stanowi oryginalna, dotychczas nie podejmowana próba wdrażania dyskursu krytycznego wobec silnie rozpowszechnionej teorii ciągłości tradycji hiszpańskiej w ramach architektury bóżnic. Jednocześnie w artykule zaprezentowano dyrektywę metodologiczną, w ramach której zakłada się, że w historii architektury priorytetem nie jest tylko uwzględnianie ergonomiczności, ale warunków społeczno-kulturowych, w których budowla istnieje. Oznacza to potrzebę interdyscyplinarnej analizy dzieła sztuki, w której uwzględnia się nie tylko opis formy, ale interpretację znaczenia, które metaforycznie ma „nosić” realizowany obiekt.
