Simply transitive NIL-affine actions of solvable Lie groups
Authors: Deré Jonas , Origlia Marcos 
Published: July 2021

Abstract
Every simply connected and connected solvable Lie group 𝐺 admits a simply transitive action on a nilpotent Lie group 𝐻 via affine transformations.
Although the existence is guaranteed, not much is known about which Lie groups 𝐺 can act simply transitively on which Lie groups 𝐻.
So far, the focus was mainly on the case where 𝐺 is also nilpotent, leading to a characterization depending only on the corresponding Lie algebras and related to the notion of post-Lie algebra structures.
This paper studies two different aspects of this problem.
First, we give a method to check whether a given action

ρ
:

G
→

Aff
⁡

(
H
)

\rho\colon G\to\operatorname{Aff}(H)

is simply transitive by looking only at the induced morphism

φ
:

g
→

aff
⁡

(
h
)

\varphi\colon\mathfrak{g}\to\operatorname{aff}(\mathfrak{h})

between the corresponding Lie algebras.
Secondly, we show how to check whether a given solvable Lie group 𝐺 acts simply transitively on a given nilpotent Lie group 𝐻, again by studying properties of the corresponding Lie algebras.
The main tool for both methods is the semisimple splitting of a solvable Lie algebra and its relation to the algebraic hull, which we also define on the level of Lie algebras.
As an application, we give a full description of the possibilities for simply transitive actions up to dimension 4.
Design and implementation of OLT switching function in 40/10G TDM-PON experimental system
Authors: Han Juntao , Yang Rongchuan , Tang Chaosheng 
Published: July 2021

Abstract
The access network is developing towards large capacity, wide-coverage, and low delay, which puts forward higher requirements for network structure and data exchange performance of optical access network equipment. In this paper, we have designed a high-speed optical network device with 40/10G TDM-PON. To effectively solve the problem of network switching capability in high-speed data transmission, we propose a low delay large capacity switching algorithm, which minimizes the network switching delay. We model the network by integer linear programming and simulate the network based on OMNeT++. The simulation results show that the algorithm can effectively solve the problem of network switching delay in the high-speed network environment.
Tunable nonlinear optical responses of few-layer graphene through lithium intercalation

Published: July 2021

Abstract
Intercalation has been demonstrated to be a powerful tool for tuning the physical and chemical properties of two-dimensional (2D) materials, providing the highest possible doping level and an ideal system to study various electronic states. In this work, we demonstrate that the nonlinear absorption effect of few-layer graphene (about 6–8 layers) is changed from saturable absorption (SA) to reverse saturable absorption (RSA) after lithium intercalation. This is attributed to the increase of Fermi energy owing to the charge transfer from Li to graphene layers in intercalated compounds (LiC6). And the change of nonlinear absorption effect is revisable after deintercalation. In addition, the modulation depth of RSA in lithiated graphene is found to rise with the decrease of incident laser wavelength, different from that of pristine graphene. Besides, the dispersion relationships of degenerate and nondegenerate two-photon absorption are analyzed from the results of nonlinear absorption and transient dynamics of lithiated graphene, indicating the 1.91–2.21 eV upshift of the Fermi surface. Our findings of the intercalation-tunable nonlinear optical absorption effect pave the way for the construction of nonlinear optical devices based on 2D intercalation compounds.
Obsidian from the Neolithic Layers of “Grotta di San Michele Arcangelo di Saracena” (Cosenza), Italy. A Preliminary Report
Authors: Forgia Vincenza , Tykot Robert H. , Vianello Andrea , Natali Elena 
Published: July 2021

Abstract
The paper presents the results obtained by techno-typological analysis of a lithic assemblage from the Neolithic layers of Grotta San Michele Arcangelo di Saracena (Cosenza) together with the results of micro-wear analysis obtained from a preliminary selection of obsidian artifacts with different provenances distinguished by pXRF analysis. The site provides one of the best preserved Neolithic sequences in the area, from the earliest Impressed Wares (or Impresse Arcaiche) (early sixth millennium BC) to the Spatarella pottery style (end fifth – early fourth millennium BC). Along the Neolithic sequence, it is possible to observe some major changes within lithic resources management. In particular, it is possible to notice some techno-typological breakages between the Early Neolithic and the further stages, until the second phase of the Late Neolithic, when another rupture, corresponding to the Spatarella facies, is evident.
Religion nach der Aufklärung
Authors: Reinhard Wolfgang 
Published: July 2021

Abstract
Dieser Beitrag zeichnet die Umdeutung von Religion und Transzendenz seit der Aufklärung nach und zeigt den damit verbundenen Macht- wie Plausibilitätsverlust des Christentums. Zwar gehört die Religion anthropologisch zum Menschen, jedoch ist sie seit der Aufklärung auf dem Rückzug. Dieser generelle Weg kann als Weg weg von der institutionalisierten Religion hin zur religiösen Praxis gezeichnet werden: Orthopraxie statt Orthodoxie. So wurde einerseits der Wahrheitsanspruch der (christlichen) Religion delegitimiert und somit unplausibel, als auch die Vorstellung Gottes, also der Transzendenz, immer immanenter und wirkungsloser wurde.

Populäre Erleuchtung oder: Im Wirkungsfeld von Aufklärung und buddhistischem Modernismus
Authors: Renger Almut-Barbara 
Published: July 2021

Abstract„Erleuchtung“ ist einer der prominentesten Begriffe, mit dem in der europäischen Kultur- und Religionsgeschichte Ideen der Vervollkommnung des Menschen zum Ausdruck gebracht worden sind. Anhand ausgewählter Beispiele umreißt das vorliegende Papier seine Entwicklung von einer Metapher in der griechischen Philosophie hin zu einem transkonfessionellen Sammelbegriff, der im Zuge der Pluralisierung von Religionen seit den 1960er Jahren eine Konjunktur in neuen, durch Markt und Medien allgemein zugänglichen Sinnstiftungsangeboten der „populären Religion“ (Knoblauch) erfahren hat. In einer Tour d’horizon, die bei Platon einsetzt und über Clemens von Alexandrien und Ps.-Dionysios Areopagita ins 18. Jahrhundert sowie in die Gegenwart führt, wird gezeigt, wie sich Vorstellungen von Licht und Erleuchtung und die Rede hierüber zu einem religiösen Begriff verdichtet haben, der über lange Zeit einen Ort im Christentum hatte, bevor er, begünstigt durch die Aufklärung, zu einer populären Kategorie wurde, die vor allem mit asiatischen, oder zumindest asiatisch inspirierten, Praktiken zur Erlangung von Heil in Verbindung gebracht wird. Der Beitrag rückt bei der Darstellung dieser Entwicklung in der Moderne Auswirkungen der Aufklärung in den Blick sowie asiatisch-euroamerikanische Beziehungsdynamiken der europäischen Kolonialzeit, die zur Entdeckung des Buddhismus als Religion führten. Haben diese doch maßgeblich dazu beigetragen, dass Erleuchtung im gegenwärtigen populären Verständnis, wie es sich beispielhaft in der sog. Satsang-Bewegung und populär-religiöser Erzähl- und Ratgeberliteratur findet, nicht mehr, wie in der neoplatonischchristlichen Prägung des Begriffs, als Zwischenstufe auf einem Weg zur Vervollkommnung gilt, sondern als Ziel und bleibender Besitz, der mit Vollendung assoziiert wird
Religiöse Praxis als Inszenierung des Unverfügbaren
Authors: Wagner-Rau Ulrike 
Published: July 2021

Abstract

Ein christlich-religiöses Verständnis des Lebens ist eng verbunden mit dem Bewusstsein der Grenzen eigener Möglichkeiten bzw. einer spezifischen Verarbeitung des Scheiterns am Vollkommenheitsideal. Dieses Wissen ist nicht nur eine Überzeugung, sondern es wird in der Gestalt vielfältiger Praktiken inkorporiert und verinnerlicht. Der Aufsatz entfaltet diesen Zusammenhang am Beispiel der protestantischen Bestattungskultur in Geschichte und Gegenwart.
Perfektion durch Evolution?
Authors: Imai Yasuo 
Published: July 2021

Abstract
Die Naturalistische Auffassung der Pädagogik scheint unaufhaltsam voranzuschreiten, wie es an der globalen Tendenzen der „learnification“ der Erziehung ablesbar ist. Naturalistische Ansätze hinterlassen in der Pädagogik sichtlich widersprüchliche Konsequenzen: die Hervorhebung der vorbestimmten und der plastischen Merkmale der menschlichen Natur und ferner die Hervorhebung der aktiven und der rezeptiven Seiten der menschlichen Plastizität. Um die komplizierte Beziehungsstruktur dieser doppelten Beidseitigkeit zu erläutern, wird auf die geschichtliche Ursprungsphase der pädagogischen Auseinandersetzungen mit dem Naturalismus zurückgegriffen: eine Auseinandersetzung mit der Evolutionstheorie in der Pädagogik in der zweiten Hälfte des 19. und am Anfang des 20. Jahrhunderts

Abstract
A chelating matrix prepared by immobilizing N-hydroxyl amine onto graphene oxide functionalized with aspartic acid (GO-HDX) was applied to recover UO2
2+ from their SO4
2− leach liquor. SEM-EDAX, FT-IR, TGA, and XRD instruments, in addition, Raman spectroscopy (IR-Raman), were used to analyze the synthesized GO-HDX. The static extraction technique optimized various physicochemical parameters that impacted the UO2
2+ extraction. The optimal pH, time of contact, initial concentration, GO-HDX dose, temp., foreign ions, and eluting agents were gained. The experimental equilibrium documents were assessed using Langmuir and Freundlich equations. The Langmuir equation model quite fits the investigational adsorption data with a maximum uptake of 277.78 mg/g, and it implied the attending of monolayer coverage of adsorbed molecules. Pseudo-first- and pseudo-second-order analyses were done to inspect the kinetic results. The data indicated that pseudo-second-order kinetics fit all concentrations. The intended thermodynamic factors were ∆G° negative values and ∆H° positive value. The data signified that the UO2
2+ extraction onto GO-HDX was spontaneous adsorption and endothermic at higher temperatures. The regeneration efficiency of GO-HDX was 98% using 1 M HCl.

Published: July 2021

Recent days the special interest towards Glasses is specifically due to their vast applications that they range. Glass series Calcium borate metallic glass (CaO–B2O3) has been prepared by melt quenching technique. CaO influences like density/molar volume ratio on the properties have analyzed and glass sample different modulus has found between them. The optical properties such as direct and indirect bandgap, Urbach energy, band gap, which also includes heat‐treated glasses, has studied by Fourier transform infrared spectroscopy and UV‐visible, respectively. According to this model elastic moduli increase, this is because of the CaO content increase. The Debye temperature, elastic moduli, other acoustic parameters and Poisson's ratio has acquired from experimental data. The obtained results show that the CaO enters into the glass network as a modifier by occupying increasing the nonbridging oxygen atoms (NBOs) and the interstitial spaces in the network.

OPTIMIZATION OF PREVENTIVE THRESHOLD FOR CONDITIONBASED MAINTENANCE OF RADIO ELECTRONIC EQUIPMENT
Authors: Solomentsev O. V. , Zaliskyi M. Yu. , Shcherbyna O. A. , Asanov M. M. 
Published: July 2021

Context. Operation costs throughout the life cycle of radio electronic equipment are very significant, which value far exceeds the initial cost of the equipment. Therefore, the up-to-date scientific and technical problem is to minimize operation costs. One of the ways to solve this problem is the introduction of statistical data processing technologies in the operation systems of radio electronic equipment.
Objective. The goal of the paper is to improve the efficiency of thecondition-based maintenance with the determining parameters monitoring, which is widely used in civil aviation.
Method. The solution of this problem is based on finding the functional dependence of the efficiency indicator in the form of specific operation costs on the basic parameters of radio electronic equipment and its operation system. To determine this dependence, the probability-event model is used,as well as methods of probability theory and mathematical statistics, in particular methods of statistical classification of sample sets and functional transformations of random variables. To determine the optimal level of the preventive threshold by the criterion of minimizing operation costs, the method of statistical simulation of Monte-Carlo is used.
Results. Maintenance strategy with the determining parameters monitoring based on additional statistical data processing and technology of the optimal preventive threshold calculation are improved.
Conclusions. The obtained results can be used during the development and modernization of operation systems of radio electronic equipment in terms of application of statistical data processing procedures. A comparative analysis of the two maintenance strategies showed that the use of additional statistical data processing might reduce specific operation costs. The proposed technology for determining the optimal preventive threshold can be extended to use during the operation of complex technical systems, in particular for those whose technical condition is associated with the values of the determining parameters.
Courtship Behavior in the Cuban Ameiva (Ameiva auberi ustulata, Squamata: Teiidae) from the Siboney-Juticí Ecological Reserve in Eastern Cuba
Authors: Alfonso Yasel U. , Torres Javier 
Published: July 2021

The genus Ameiva Meyer 1795 comprises 23 species of which 14 are found in Central and South America and 18 occur in the West Indies. These lizards occupy diverse habitats (e.g., grasslands, tropical forests, sandy beaches) but most species appear to prefer open areas. They are ground-dwellers and active diurnal foragers. Cuba harbors only one species, Ameiva auberi. However, 40 subspecies are distributed widely across the main island, adjacent cays, and on into the Bahamas. Reproductive behavior has been documanted in some species in the family Teiidae, but not for A. auberi, about which only one published account reported the underground deposition of a single egg. Herein, we describe for the first time the reproductive behavior (except ovipositioning) of A. auberi ustulata in natural habitat in the Ecological Reserve Siboney-Jutici (eastern Cuba) on 22-25 July 2009. Between 1200 and 1600 h, we observed six mating pairs directly or while using monocular Nikon Fieldscopes. We describe three sequential stages of reproductive behaviior: (1) Pursuit, (2) prematiing and mating, and (3) excavation, with a total duration of 64.8+-17.6 min (46-92 min).
Male movement patterns and bioacoustic activity of the Western Cuban Grassfrog, Eleutherodactylus varleyi (Anura: Eleutherodactylidae)
Authors: Cádiz Antonio , Iturriaga Manuel 
Published: July 2021

In this study, we examined movement patterns, vocal activity, and variation in advertisement calls at individual and populational levels in a population of Western Cuban Grassfrogs (Eleutherodactylus varleyi) at the National Botanical Garden of Cuba in July and September in 2007. Males appear to be very sedentary with peaks of movement early in the night and just before dawn that could be related with the search of calling sites and diurnal retreats, respectively. We detected eight patterns of frequency modulation of advertisement calls for note 1 and six for note 2. Patterns II and VI were the most frequent for note 1 and note 2, respectively. Note duration was the only acoustic parameter that was significantly variable among individuals for note 1, whereas the maximum frequency and rise time were signifi- cantly variable within individuals for note 2, suggesting that the latter is more reliable for distinguishing individual calls.

Authors: Shpagina L. A. , Panacheva L. A. , Zolotukhina E. V. 
Published: July 2021

Objective. Taking into account a high prevalence of occupational pathology associated with the exposure of industrial aerosols, to analyze the principles of therapy used for patients with these diseases.
Materials and methods. The regulating medical documents, the data of preventive medical examinations as well as the principles of therapy applied for patients with occupational diseases, which are presented in scientific literarure, are analyzed.
Results. The role of harmful production factors in the formation of pneumoconiosis and alveolitis, which join the group of interstitial lung diseases (ILD), has been proved. The outcome of these occupational diseases is fibrosing alveolitis with the development of diffuse pulmonary fibrosis. In the treatment of ILD, immunobiological drugs (IBD) are used to suppress the immune processes selectively affecting the monoclonal antibodies, blocking of which interrupts inflammation and in 90 % of cases stops the further development of the disease.
Conclusions. The use of immunobiological drugs in clinical practice should be carried out within the framework of ethical and legal regulation between the patient and the doctor.

Materials and methods. The regulatory framework of domestic professional pathology regarding examination of relationship between diseases and profession is evaluated
Results. It was noted that for the specified period, in the normative acts the organizational issues of the examination of the connection between the disease and the profession did not have a satisfactory solution. A feature of most regulatory documents in the field under consideration, issued recently, is a certain logical inconsistency.
Conclusions. To radically improve the current situation, it is necessary to immediately adopt for practical application the mandatory criteria, which prove the occupational origin of health disorders in workers.

The ascending aortic aneurysm occurs in 45 % of cases from the total number of aortic aneurysms of various localization. The incidence rate of combination of the aortic disease with aneurysm per 100 000 of the population is 5.9. The problem of prosthetics of the aortic root and aortic valve due to aneurysm and the changed AV is rather actual. The main principle of aneurysm surgery is the prevention of the risk of dissection and rupture with reconstruction of normal dimensions of the ascending aorta. Currently, there are different techniques for the treatment of root aneurysms and ascending aorta. The standard techniques are aortic root replacement, aortic valve reconstruction with replacement of aortic root or ascending aorta and partial or full replacement of aortic arch depending on the situation.
The Bentall De Bono operation at present remains a golden standard of surgical treatment of the aneurysms of the root and ascending aorta with changed aortic valve. This surgery can have the following complications: thrombotic, thromboembolic followed by conduit dysfunction, formation of false anastomosis aneurysms, hemorrhage, compression of coronary artery orifices due to tension in the zone of coronary anastomoses.
