The “Core Actions” and “Uniquely Colorful Lyricism” of New Mainstream Films
Authors: Zhou Anhua
Published: July 2022

In 2020, new domestic mainstream films continued to challenge audience expectations and achieve breakthroughs. These films not only are characterized by representations that are universally appealing to contemporary tastes, but also integrate the desires and interests of the public. They have become mainstream films because they are full of realistic content and true sentiments. Regarding the narrative esthetics and ideological strategies of these films, the three new “core actions” make the powerful trend of “uniquely colorful lyricism” appear brilliantly on the screen. These core actions are: (1) revealing the true nature of life and struggle by strengthening the sense of opposing forces; (2) emphasizing comedic elements to highlight low-level esthetic charms; and (3) creating open spaces and thematic implications through the use of different phases. Obviously, it has been the inevitable choice of new mainstream films to restore sincerity and truth of the screen, to sense the changes in people and society, and to interpret the new modern and contemporary histories in ways that originated from, but rise above, reality.
Overexpression of miR-100-5p inhibits papillary thyroid cancer progression via targeting FZD8
Authors: Ma Peng , Han Jianli
Published: July 2022

Papillary thyroid cancer (PTC) is the most prevalent type of TC worldwide; however, its pathological process remains unclear at the molecular level. In the current study, we analyzed the microarray data of PTC tissues and non-neoplastic thyroid tissues, and confirmed miR-100-5p as a downregulated miRNA in PTC. Via bioinformatic approach, western blotting, and TOP/FOP-flash assay, miR-100-5p was observed to be involved in the inactivation of Wnt/β-catenin signaling in TPC-1 and KTC-1. Frizzled Class Receptor 8 (FZD8), the coupled receptor for canonical Wnt/β-catenin signaling, was verified to be targeted and inhibited by miR-100-5p in TPC-1 and KTC-1. In the function assay, miR-100-5p mimic repressed PTC cell proliferation and induced cell apoptosis of TPC-1 and KTC-1; meanwhile, transfection of full-length FZD8 attenuated the effect of miR-100-5p mimic. Moreover, in the collected samples, miR-100-5p was lowly expressed in PTC tissues compared with normal tissues, especially in those of advanced stage (Stage III/IV vs Stage I/II), while FZD8 was highly expressed in PTC tissues, which in PTC tissues was inversely correlated to miR-100-5p. Thus, we suggest that overexpression of miR-100-5p inhibits the development of PTC by targeting FZD8.

Authors: Han Xuan , Ren Peng , Ma Shaohua
Published: July 2022

Youth-onset non-small cell lung cancer (NSCLC) is a heterogeneous disease. It has a unique clinicopathology and special genetic background. In this study, three key genes, CDC20, CCNB2, and BUB1, have been identified in youth-onset NSCLC tumor tissues based on the TCGA and GEO cohorts. Functional enrichment analysis reveals that the “oocyte meiosis,” “cell cycle,” and the “P53 signaling pathway” are significantly enriched. Additionally, four survival genes, including AKAP12, CRIM1, FEN1, and SLC7A11, that affect the prognosis of youth-onset NSCLC patients are identified in this study. Finally, we construct a risk model to predict the overall survival of youth-onset NSCLC patients, the AUC of the risk model in 1, 3, and 5 years of overall survival is 0.808, 0.844, and 0.728. This study aims to provide a novel idea to explore the pathogenic genes of youth-onset NSCLC.
Bioinformatics-based analysis of SUMOylation-related genes in hepatocellular carcinoma reveals a role of upregulated SAE1 in promoting cell proliferation
Authors: Liu Yang , Wang Xiang , Zeng Xingzhi , Wu Yinghua , Liu Xinrong , Tan Juan , Li Xiaoyan
Published: July 2022

The function of small ubiquitin-like modifier (SUMO)-related genes in hepatocellular carcinoma (HCC) remains unclear. This study aimed to analyze the expression profile and prognostic relevance of SUMO-related genes using publicly available data. A set of bioinformatics tools and experiments were integrated to explore the mechanism of the genes of interest. The least absolute shrinkage and selection operator Cox regression analysis was used to construct a prognostic model. SUMO-2 and SUMO-activating enzyme subunit 1 (SAE1) were upregulated in HCC. The enrichment analysis indicated that SUMO-2 and SAE1 might regulate the cell cycle. The downregulation of SAE1 inhibited the proliferation of HCC cells, whereas the upregulation of the gene promoted cell proliferation. IGF2BP3 contributed to the upregulation of SAE1 in an N6-methyladenosine (m6A)-dependent way. Eventually, an SAE1-related risk score (SRRS) was developed and validated in HCC. SRRS could serve as an independent prognostic factor and predict the efficiency of transarterial chemoembolization in patients with HCC.

Published: July 2022

The effects of thermomechanical processing on the grain size, tensile strength, and strain rate of a CuZn10 alloy were investigated. Microstructures of thermomechanically treated samples were introduced using a scanning electron microscope. The relationships between the flow stress, reduction ratio, annealing temperatures, and strain rates were detected for determination of activation energies and optimized thermomechanical parameters. The effect of grain size on the mechanical properties was examined by tensile and microhardness tests. The typical fractographs of samples after tensile tests were examined using a scanning electron microscope. It was observed that the annealing temperature and aging time have significant effects on the optimum grain size. Mechanical properties of the thermomechanically treated samples were improved by strain rate, deformation ratio, annealing temperature, and aging time.

The finite element modeling of the impacting process of hard particles on pump components
Authors: Li Qingyu , Jing Laiyi , Sun Qunying , Ji Li , Chen Songying
Published: July 2022

Shield pumps which transport a variety of complex media are widely used in chemical industry, mineral industry, and other fields. However, the hard particles in the media erode the flow passage in the shield pump, seriously affecting the service life of the pump. Therefore, it is important to study the erosion process in the flow passage to extend the service life of the pump. This erosion process in the shield pump can be investigated by experiments, but it is difficult for the current experimental method to copy the real industrial service environment of impellers. For example, the environment temperature and speed range are found difficult to be reached by the current experimental method. Comparatively, the simulation by finite element method can overcome the above deficiency. In this article, the ANASYS software is used to simulate the erosion process in shield pump flow passage due to hard particles. Specifically, the structural static analysis module is used to build the model of thermal barrier coating components and hard particle components. Then the variation law of stress, strain, and material deformation of the flow passage components under concentrated force is obtained. Second, the extended finite element method is used to study the crack propagation caused by the erosion process. A linear elastic–linear softening constitutive model is established to simulate the stress variation during the crack propagation and material removal under the continuous erosion from hard particles. The proposed law regarding stress variation and crack propagation in the erosion process in this study contributes to theoretical support for damage detection and service life extension of shield pumps.
The university of the future and lecturer identity
Authors: Moon Christopher J.
Published: July 2022

This keynote address builds on several papers I have written concerning ‘the university of the future’. An initial blog for the Higher Education Academy (Moon, 2017) entitled, 95 theses for reforming Higher Education. Are HEI’s catalysts for a sustainable society?, set the scene and provided the stimulus for considering how the collective identity of the university has changed since inception and still presents tensions and challenges today. Subsequent papers published by Moon (2019, 2021) build on this foundation to present an argument that societal ‘impact’ can be used to cut through the tensions in a way that galvanises staffs and students around common themes and values such as identified with the United Nations Sustainable Development Goals (SDG’s). In this keynote address I regard lecturer identity as a dynamic process which is influenced by the above tensions and challenges, and further explore how societal Impact can be used to build lecturer identity including examples from my own pedagogic practice.

This is a cross-sectional, descriptive and correlational research with quantitative methodology. 2112 people over 18 years of age participated. For the analysis of depressed mood, the CES-D questionnaire was administered and to empathic capacities and personal strength the resilience scale for the study of resilient protective factors. The results of the ANOVA statistic and the linear regression carried out indicate the high degree of association and predictive capacity of the dimensions, empathic capacities and personal strength, with respect to the depressed. In conclusion the depressive mood in the Spanish population during confinement caused by COVID-19 is determined by empathic capacities and personal strength.
Von der Konstitutionalisierung von Nulla poena, nullum crimen sine lege in Art. 116 WRV (1919) zu dessen Umkehrung in ein Nullum crimen sine poenadurch das NS-Regime
Authors:   Humboldt-Universität zu Berlin (Humboldt University of Berlin, Germany), Heger Martin
Published: July 2022

The principle of Legality (nullum crimen, nulla poena sine lege) is the most fundamental principle of German criminal code since it was codified in the Bavarian Criminal Code 1813 for the first time. With the Foundation of the German Empire in 1871 it became an integral part of the new German Penal Code Reichsstrafgesetzbuch). It was constitutionalized in 1919 as a fundamental right with Art. 116 of the Weimar Constitution. It was unchallenged till the Nazi regime came to power. Not within the Empowerment Act but with other legal measures resulting from the burning of the Parliament (”Reichstagsbrand”) on 28 February 1933 till 1935 on, the Nazi regime changed the principle step by step from nullum crimen, nulla poena sine lege to nullum crimen sine poena. They made Analogy in disfavor of the accused person possible and they stated criminal offences with retroactivity. Unfortunately, the Supreme Court of Justice (Reichsgericht) accepted the new provisions and used it as a basis for its sentences. After WW II the allies nullified the Nazi provisions. With Art. 103 § 2 of the new (West-)German constitution from 1949 nulla poena sine lege has been constitutionalized again. The Paper deals with that development with a special focus on the role of the Reichsgericht as the highest body of judges, who were trained in the times before the Nazis came to power.
Constitutionality in the Kingdom of Serbs, Croats, and Slovenes/the Kingdom of Yugoslavia – Between Covert and Overt Dictatorship
Authors:   Универзитет у Источном Сарајеву (University of East Sarajevo, Bosnia and Herzegovina), Savić Sanja
Published: July 2022

The Kingdom of Serbs, Croats, and Slovenes was created on December 1, 1918 by proclamation of Regent Alexander I Karadjordjevic. The most important step regarding the organization of the newly formed state was the adoption of the constitution. The first constitution of the newly formed state was adopted on June 28, 1921, and in science it is usually called the Vidovdan Constitution. Due to a series of internal problems, on January 6, 1929, the king suspended the Vidovdan Constitution, dissolved the assembly and banned the work of political parties, and justified the coup by the highest national and state interests. The transition to an open dictatorship did not solve any of the political, economic, or national problems that led to the crisis. Despite the fact that the king announced his return to the constitutional order as soon as possible, this would happen only after two years. With the enactment of the constitution on September 3, 1931, there was no democratization of Yugoslav society, but the king’s open dictatorship was replaced by a constitutional one. The existence of the Kingdom of Serbs, Croats, and Slovenes/Yugoslavia in the period 1918–1941 in a political sense, was marked by the changes of a covert and open dictatorship, whereby the proclaimed democratic rights and freedoms represented only a show for the public. Through the paper, the author will analyze those constitutional provisions and the king’s actions that indicate this.
Die Weimarer Reichsverfassung und das Verbot rückwirkender Strafverschärfung
Authors:   Universität Hamburg (Hamburg University, Germany), Kuhli Milan
Published: July 2022

The principle “nullum crimen, nulla poena sine lege” is one of the core principles of German criminal law and constitutional law. However, the history of this principle is quite varied. This article will focus on an essential part of this history, namely on the version of this principle in the Weimar Constitution of 1919. It will be shown that the principle of legality of criminal law was indeed expressed in that constitution, but that the exact scope of application of this constitutional principle was quite unclear. In this regard, it was uncertain whether the Weimar Constitution also prohibited the retroactive application of criminal laws to those cases for which a more lenient penalty was provided at the time of the offense. This ambiguity of the Weimar Constitution finally became apparent in 1933 in the so-called Reichstagsbrandprozess (Reichstag fire trial). The issue in these criminal proceedings was whether the burning of the parliament building in Berlin (February 27, 1933) was punishable by death, although this sanction was not provided at the time the crime was committed. In this essay, it will be shown that the National Socialists had to go to considerable effort to be able to ignore prohibitions on retroactivity. This undermining of the principle “nullum crimen, nulla poena sine lege” forms an important example of the willingness of the legislature to negate essential protective principles of law in the Third Reich.
Powstanie i kulisy uchwalenia ustawy przechodniej z dnia 18 maja 1921 r. do Ustawy Konstytucyjnej z dnia 17 marca 1921 r. w sprawie czasowej organizacji władzy zwierzchniej Rzeczypospolitej

On February 10, 1919, the Legislative Seym met for the first session, whose main goal was to prepare a draft of the basic law for the reborn Poland. Over the next few months, in a specially created constitutional commission, work was carried out to create and submit to the Legislative Seym a draft of a new constitution. However, in order to ensure at least the basic framework for the functioning of the state, on February 20, 1919, a resolution of the Legislative Seym was passed entrusting Józef Piłsudski with the further exercise of the office of the Head of State. This resolution, commonly known as the Small Constitution, was formally in force until June 1, 1921, i.e. the day the March Constitution was announced. Despite the formal repeal of these provisions, they continued to function. In relation to the Seym, the provisions of the Small Constitution were formally in force until November 28, 1922, and in relation to the Head of State until December 14, 1922. However, due to noticing a legislative error in the Small Constitution and in the passing regulations, the provisions of the March Constitution were adopted on May 18, 1921; the Act passed to the Constitutional Act of March 17, 1921 on the temporary organization of the supreme power of the Republic, which “patched up” the incorrectly formulated provisions in the Small Constitution. The work was based on the literature on the Basic Law of 1921, draft laws and amendments presented in the Constitutional Committee, as well as on numerous shorthandings from the sessions of the Legislative Seym, the Seym of the Republic of Poland and the National Assembly.

Published: July 2022

The paper sheds light on the summary criminal court formed on the occasion of the Hussar Rebellion (‘Katanska buna’, 1844), an unsuccessful rebellious attempt to overthrow the regime of the Defenders of the Constitution in Serbia. The author shall firstly provide a short introductory account of the rebellion, after which the formation and work of the summary criminal court shall be analyzed. Some sort of ‘pre-investigation’, conducted by Toma Vučić Perišić, the most distinguished personality within the regime of the Defenders of the Constitution, was provided with an unlimited mandate to quell the rebellion. The appointment and personalities of the judges will also be the subject of scrutiny, since it is an indication of the (im) partiality of a trial. The exposition will then continue with the lines having an inquiry carried out by the summary criminal court for the topic; the author shall put forward the presentation of evidence (the statements of the suspects, confrontations between the suspects, witness’ statements, confrontations between suspects and witnesses, documentary evidence and guarantors). The next part of the paper shall be judgmentpassing; among the questions belonging to that matter, punishments, the mental element, mitigating/aggravating circumstances, and illegalities committed by the court in that stage of the proceedings will all be presented to the readers.

Published: July 2022

Objective

Endogenous hypercortisolism predisposes to impaired immune function and infections. To date, however, it is unknown whether there is a subtype-specific pattern in white blood cell (WBC) and WBC differential (WBCD) count.

Methods

A retrospective monocentric cohort study was carried out in patients with overt endogenous Cushing’s syndrome (CS) or adrenal incidentalomas and autonomous cortisol secretion (ACS), with WBC/WBCD analysis at initial diagnosis and after biochemical remission. Cut-offs were obtained by receiver-operating characteristics analysis.

Results

In total, 253 patients were analyzed (Cushing’s disease (CD); n  = 88; ectopic CS (ECS), n  = 31; cortisol-producing adrenal adenomas (CPA), n  = 40; ACS, n  = 45; adrenocortical carcinomas (ACC), n  = 49). Total leukocytes and neutrophils correlated positively with serum cortisol after 1-mg dexamethasone (r = 0.314 and r = 0.428), while a negative correlation was observed for lymphocytes and eosinophils (r = −0.374 and r= −0.380) (each P < 0.0001). Similar observations were made for 24 h-urinary free cortisol. CD and ECS differed in numbers of neutrophils and lymphocytes (P < 0.0001) and were well differentiated at a cut-off of 6.1 for the neutrophil/lymphocyte ratio (sensitivity 90.0%, specificity 89.4%, and areas under the curve (AUC) 0.918). For adrenocorticotropic hormone (ACTH)-independent CS, the best diagnostic outcome was obtained for the discrimination of CPA and ACC at a cut-off of 187.9 for the platelet/lymphocyte ratio (sensitivity 59.6%, specificity 80.6%, and AUC 0.713). For ECS, CPA, and CD, neutrophils decreased (delta −47.0, −29.7, and −26.2%) and lymphocytes increased (+123.2, +78.1, and +17.7%) already 3 months after remission.

Conclusion

Most immune cells correlate with the degree of hypercortisolism and differ among CS subtypes. WBCD changes are already identified 3 months after remission from endogenous hypercortisolism.

Comunicación, cultura y política: de la ‘primera New Left’ a la formación de los estudios culturales británicos (1956 – 1979)
Authors: Llanes Jove Jorge
Published: July 2022

El objetivo de este artículo es realizar un recorrido histórico y teórico que permita trazar la genealogía de los estudios culturales británicos a partir del nacimiento de la New Left en la segunda mitad del siglo XX. Se realiza un análisis del contexto político de la naciente sociedad de consumo de posguerra, así como de los desarrollos teóricos que buscaron dar cuenta del cambio cultural favorecido por el aumento de la disposición y acceso a los bienes de consumo, la extensión de la alfabetización, el desarrollo de los medios de comunicación de masas y la proliferación de nuevas formas culturales y estilos de vida. Se exponen las aportaciones fundamentales de E.P.Thompson, Richard Hoggart, Raymond Williams y Stuart Hall, y se detallan los puntos críticos de encuentro y desencuentro que permiten hablar de una ‘primera New Left’ durante el período 1956-1962, así como de un proyecto original de los estudios culturales británicos durante la etapa 1964 – 1979. En última instancia, se expone la naturaleza del debate teórico que conduce a la centralidad, dentro de los estudios culturales, del fenómeno de la significación y la perspectiva semiótica de la cultura como paradigma de análisis de la influencia de los medios de comunicación en la construcción de la realidad social. El artículo concluye con un esbozo de los puntos de inflexión que, en gran medida, permiten entender la ambigüedad de los desarrollos, fundamentalmente teóricos y académicos, de los estudios culturales a partir de 1980, en detrimento de la voluntad popular de la primera etapa.
Complete Thoracoscopic Resection of Left Ventricular Myxoma – A Case Report
Authors: Li Gang , Wang Jian , Liu Zhi-Ping , Du Yi-Ri , Tian Ze-Xiang
Published: July 2022

Cardiac myxoma is a common cardiac tumor. Most are found in the left cardiac system, of which 75% of myxomas are located in the left atrium [Pinede 2001], and the origin of the left ventricle is relatively rare. Surgical resection is the most effective method for the treatment of myxoma, but because of the complex anatomy of the left ventricle, most of the reported cases are performed through the traditional median thoracotomy through the ascending aorta and vena cava to establish cardiopulmonary bypass. It is rare to establish cardiopulmonary bypass through the femoral artery and femoral vein to remove left ventricular myxoma under complete video-assisted thoracoscopy. This paper reports the surgical process and perioperative echocardiographic, magnetic resonance, radiological and pathological features of a completely thoracoscopic resection of left ventricular myxoma.
La dimensión financiera de la cooperación Sur-Sur: reflexiones en torno a sus perspectivas y potencial en la coyuntura pandémica
Authors: Abbondanzieri Camila
Published: July 2022

Nowadays the role of South-South cooperation has acquired particular connotations. These particularities are part of an eroded international scenario defined by North-South flows of asymmetric traditional cooperation. All this happens in a context characterized by proliferation of institutions connecting partners within the global South and also due to the creation of regional development funds worldwide. Because of the crisis of the multilateralism and the weakening of the traditional channels and practices of international cooperation, several international organizations and experts acknowledge the need for including all possible efforts to overcome the recession deepened by the pandemic. Thus, the South-South cooperation role is highlighted as part of these efforts. Therefore, the objective of this article is to analyze the financial dimension of South-South cooperation to determine to what extent it can be considered as a key tool in the projection of assertive actions within the pandemic context and from the global South perspective. It is argued that, although this cooperation should not monopolize all the responses coming from the South, it entails a possibility in a process of diversification of cooperation alternatives aiming to position itself in the international scenario.

Published: July 2022

Este trabajo estudia la designación del señor de Chantonnay como embajador de Felipe II en el Sacro Imperio. Su arribo se produjo porque el cardenal Granvelle, su hermano, utilizó su red de contactos en Madrid. Este hecho muestra el posicionamiento faccional de los Perrenot de Granvelle en las cortes de Madrid y Bruselas, así como sus objetivos familiares: evitar la caída en desgracia y extender su influencia en la corte imperial. Así, ellos son un ejemplo de nobleza transregional que balancearon sus intereses personales con el servicio dinástico de los Habsburgo.
Expresiones populares del espíritu "festivo" de los jesuitas en España, América y Portugal
Authors: López Miguel L.
Published: July 2022

Este ensayo es una aproximación a manifestaciones cotidianas de ciertos jesuitas españoles establecidos en Italia tras el extrañamiento decretado por Carlos III en 1767. Durante casi cuarenta años muchos de ellos, en medio de un ambiente no siempre amable y con la nostalgia de la patria y sobre todo del esplendor perdido, desarrollaron una intensa labor intelectual que ha dejado obras magistrales en los más diversos campos del saber. Pero este no es el único rastro de las inquietudes que nos han dejado. Hay también expresiones más espontáneas y vulgares. Deben entenderse como expresión de un espíritu vivaz y festivo, cuyo alcance es imposible descifrar, pero es seguro que compartían algunos miembros de la orden que tuvieron que adaptar sus parámetros vitales a la siempre traumática experiencia del exilio.

We have reviewed main peculiarities of amplitude and phase transmission/reflection spectra of different model semiconductor structures, including bare dielectric substrate, thin conductive layer placed between two dielectric media, thin conductive layer on dielectric substrate and hybrid plasmonic structures with thin conductive layer under metallic grating. The analysis has been performed using the analytical expressions obtained as a result of solving the Maxwell equations at normal incidence of plane electromagnetic waves. We have shown that specific behavior of the amplitude and phase spectra in THz frequency range can be used to determine basic electric parameters of electron gas, including electron concentration and electron mobility, in the framework of advanced THz time-domain measurements. Finally, we proposed efficient, electrically-controllable THz phase modulator based on effect of two-dimensional plasmon resonances in hybrid plasmonic structure with a spatially modulated electron concentration in a thin conductive layer.

From the position of conceptions inherent to semiconductor physics and semiconductor technology, the processes occurring in conductors of the second class, which take place due to the current flow in them, have been considered in this paper. It has been shown that using the several composite materials consisting of a porous matrix filled with an electrolyte enables to obtain multilayer structures, in which potential barriers appear in the electrolyte medium. These barriers are caused by the difference in properties inherent to layers of porous matrix. Considered here has been the prospect of creating the new devices based on the second-class conductors capable to control the direction and magnitude of the current flow in these conductors that are in a liquid state (in electrolytes). In other words, it was considered the possibility to obtain the ionic devices that are closest in their functional properties to basic electronic devices, such as diodes, transistors, etc.

Cu–Al–O thin films were grown on Si (111) substrates by using the reactive ion-beam sputtering (RIBS) method within the temperature range 80 to 380 °C. The effect of thermal annealing of Cu–Al–O films under various regimes of cooling on the microstructure, morphology, optical properties and photocatalytic activity were examined. The properties of annealed Cu–Al–O films were studied using atomic force microscope (AFM), energy dispersive X-ray spectroscopy (EDX), and Fourier transform infrared spectrometry (FTIR). The X-ray diffraction patterns show appearance only CuAl2O4 phase after thermal annealing of Cu–Al–O thin films at 900 °C. Raman scattering confocal measurements have also confirmed the presence of CuO phases in annealed Cu–Al–O samples. AFM results have indicated that the greatest RMS roughness is observed in CuAl2O4 films after temperature annealing under the fast cooling regime. Photodegradation of CuAl2O4 films was investigated using methyl orange as model pollutant. Present results indicate that CuAl2O4 photocatalysts are potential candidate for the practical application in photocatalytic degradation of organic compounds.

Amplification of a dosimetric EPR signal in mineralized biological materials available in limited quantities has been demonstrated in this paper. Powders of irradiated enamel, dentin, and bone tissue were placed into silica ampoules with the outer diameter close to 1.4 mm. To amplify the signal, the dielectric insert in the form of cylinder with the outer radius 2.85 mm, the inner radius 0.75 mm, and the height 1.85 mm made of a high-κ and low-loss ceramic material BaTi4O9 + 8.5% ZnO has been used. It has been shown that maximum signal amplification (about an order of magnitude) has been achieved when the sample is completely inserted into this dielectric. It has been found that the line shape of the dosimetric signal is not distorted, if using the dielectric insert. Decomposition of the amplified EPR spectra allowed us to determine the relative contribution of two types of CO2– radicals to the dosimetric signal, which coincides with the literature data.

The magneto-optical Kerr effect in Gd20Co80 alloy and cobalt thin films has been studied in a broad spectral range applying spectral ellipsometry experimental technique. The results of the experiments showed the complex nature of the complex Kerr angle dispersion curves. A quantum mechanical formalism for degenerate and non-degenerate Landau levels for quasi-free electrons in ferromagnetic material has been developed in order to analyze the experimental data. The equivalence of relations for off-diagonal dielectric tensor elements for non-degenerate Landau levels to the classical case of the motion of quasi-free electrons along circular trajectories in a magnetic field has been theoretically shown. The degenerate Landau levels in this approach are the result of motion of electrons in small confined volumes near rare-earth alloy atoms. Rotation of light polarization occurs in this case due to transitions between subbands having different magnetic quantum numbers. This theoretical approach allowed us to interpret in detail shapes and sign of the complex Kerr angle dispersion curves, which actually include the contributions of optical transitions between degenerate and non-degenerate energy levels. The complex Kerr angle sign is determined by the magnetization magnetic field direction for non-degenerate Landau levels and the Hund rule for degenerate Landau levels.

Published: July 2022

The objective of this work is to study the differential cross- section in the presence of a weak laser field (visible and UV) in the case of inelastic scattering. When the target absorbs the energy, the differential cross section increases, according to the theoretically constructed model. The differential cross-section initially decreases to a minimum and finally takes a maximum value, when the target emits the energy. The energy emission occurs at 5 eV, 10 eV, 13 eV, 16 eV, 20 eV, 25 eV, and 30 eV. In addition, the differential cross-section also increases with the scattering angle.

Теоретично дослiджено електродинамiчну систему, в якiй замагнiчений трубчастий пучок електронiв обдуває цилiндричний плазмово-твердотiльний хвилевiд. Встановлено, що у разi виконання квазiстацiонарних умов у хвилеводi збуджуються гiбриднi об’ємно-поверхневi або поверхневi електромагнiтнi хвилi гелiконного походження. Збудження власних хвиль хвилеводу здiйснюється полем просторового заряду пучка iз узгодженням поздовжнiх спектральних складових електричного поля. Вiдзначено ефект невзаємностi власних хвиль хвилеводу з iдентичною структурою розподiлу полiв, але таких, що вiдрiзняються поширенням в азимутальному напрямi, а також у разi змiни напряму зовнiшнього магнiтного поля. Показано, що нестiйкiсть зв’язаних хвиль електродинамiчної системи зумовлена ефектом Вавiлова–Черенкова.

Встановлено, що параметри та об’єм елементарної комiрки домiшкових кристалiв майже лiнiйно зростають зi збiльшенням концентрацiї домiшки порiвняно з чистим кристалом, тодi як показники заломлення ni домiшкових кристалiв дещо зменшуються (∼2,5 · 10−3), однак спiввiдношення мiж ними (nz > nx > ny та dnz /dλ > dnx/dλ > dny /dλ ) залишаються незмiнними. Розраховано зонно-енергетичну структуру кристалiв з 1,7% вмiстом мiдi та виявлено, що зi зростанням концентрацiї ширина забороненої зони зменшується.

The fundamental group of the space $\Omega_n(m)$
Authors: Pasko A.M.
Published: July 2022

In the present paper the spaces $\Omega_n(m)$ are considered. The spaces $\Omega_n(m)$, introduced in 2018 by A.M. Pasko and Y.O. Orekhova, are the generalization of the spaces $\Omega_n$ (the space $\Omega_n(2)$ coincides with $\Omega_n$). The investigation of homotopy properties of the spaces $\Omega_n$ has been started by V.I. Ruban in 1985 and followed by V.A. Koshcheev, A.M. Pasko. In particular V.A. Koshcheev has proved that the spaces $\Omega_n$ are simply connected. We generalized this result proving that all the spaces $\Omega_n(m)$ are simply connected. In order to prove the simply connectedness of the space $\Omega_n(m)$ we consider the 1-skeleton of this space. Using 1-cells we form the closed ways that create the fundamental group of the space $\Omega_n(m)$. Using 2-cells we show that all these closed ways are equivalent to the trivial way. So the fundamental group of the space $\Omega_n(m)$ is trivial and the space $\Omega_n(m)$ is simply connected.
Effect of Different Obturation Techniques on Sealer Penetration into Dentinal Tubules after Final Irrigation with XP-Endo Finisher File
Authors: Demir Erhan , Kamalı Selin Göker , Türkaydın Dilek
Published: July 2022

The first objective of this research was to evaluate the effectiveness of XP-Endo Finisher on dentinal tubule penetration of irrigation solution using confocal laser scanning microscopy. The main purpose of this research was to compare the effect of cold lateral condensation, continuous wave obturation and core-carrier based techniques on sealer penetration. Sixty mandibular premolars were prepared and allocated into two experimental groups (n=30) as the final irrigation technique and obturation technique experiment. In the final irrigation technique experiment, final irrigation was performed with XP-Endo Finisher, passive ultrasonic irrigation (PUI) and conventional needle irrigation (CNI) (n=10). The roots in the obturation technique experiment were also assigned into 3 groups and obturated with cold lateral condensation, continuous-wave obturation and core-carrier techniques (n=10). The most effective activation method, which emerged as a result of the first part of this study, was used as the final irrigation method in the obturation technique experiment. Then, all roots were sectioned in 1-mm-thick slices at 3mm from the apex for scanning. In terms of depth and percentage of material penetration, CNI exhibited significantly the lowest values and no significant difference was found between others. Also, there was no significant difference among obturation methods. In conclusion, XP-Endo Finisher and PUI are more effective than CNI on irrigant penetration. Sealer penetration into dentinal tubules is independent of obturation techniques.
Atenuación de los espectros de respuesta en problemas de amenaza sísmica. ¿Uso directo de relaciones originales publicadas o corrección de éstas por características locales? Caso de estudio Nicaragua
Authors: Álvarez Leonardo
Published: July 2022

Se presenta un análisis de los espectros de respuesta de la aceleración (ERA) registrados en Nicaragua y su comparación con los que predicen diferentes relaciones de atenuación publicadas (se usa la media geométrica de las componentes horizontales). Se discute un procedimiento para modificar relaciones de atenuación publicadas para su uso local, basado en el análisis de los residuos de los ERA observados, convertidos al valor esperado en roca rígida (VS30 = 1130 m/seg), respecto a las predichas por las relaciones de atenuación ln{ERAobservado(T)} - ln{ERApredicción(T)}. La modificación toma la forma de una corrección Q(μi,σi) con “i” variando sobre los períodos del espectro, donde “μ” es el sesgo y “σ” la dispersión estándar. Se propone un procedimiento para su uso en estimados de amenaza sísmica, que consiste en usar las relaciones modificadas para roca rígida en los cálculos y convertir los espectros de amenaza uniforme obtenidos a la VS30 deseada usando el mismo método empleado para convertir los ERA observados al valor de roca rígida. Se considera que este procedimiento arroja resultados más confiables que cuando se usan directamente relaciones de atenuación publicadas.
