Diasporic Chinese family drama through a transnational lens: The Wedding Banquet (1993) and Saving Face (2004)
Authors: Han Qijun
Published: December 2019

The immigrant Chinese family has increasingly been represented in transnational Chinese cinema(s) over the past three decades. Two representative films, The Wedding Banquet (Lee, 1993) and Saving Face (Wu, 2004), are chosen to shed light on Chinese filmmakers' engagement with the complex process of identity formation for immigrants through the artifice of family conflict. Both movies examine how homosexuality can pose a threat to traditional Chinese family ethics such as filial piety, family continuity and family reputation, and how the seemingly incompatible ideological standpoints can be accommodated in the end. In both cases, on the one hand the depicted denial of homosexuality comes from its association with failed family education and bad ethnic and cultural practice, and its violation of traditional Chinese values. Therefore, sexuality becomes linked to the effect of Americanization and what it means to be Chinese. On the other hand, the 'undesirable' homosexual identity can be accepted or at least tolerated within the family as long as the family lineage is ensured, or the family remains intact. The disaporic subjects show us that submission to one's ethnicity can be modified or unlearned.
Változó attitűdök a szleng használatában
Authors: Parapatics Andrea
Published: December 2019

A dolgozat a mai magyar nyelvhasználat egyre látványosabban megnyilvánuló, sajátos nyelvi és társadalmi kérdésével foglalkozik: azzal, hogy a felnövekvő nemzedék tagjai milyen nyelvi attitűdökkel viseltetnek az idők során változatos szerepköröket betöltő, nemcsak szókészletét, hanem státuszát és stílusát tekintve is állandóan módosuló szleng iránt, hogy ez milyen hatással van az őket körülvevő és nevelő idősebbek, a szélesebb magyar beszélőközösség nyelvi mentalitására és fordítva, s hogy mindezek hátterében milyen nyelvi és társadalmi változások állnak. A kutatás elsősorban a fiataloktól változatos módszerekkel gyűjtött objektív és szubjektív nyelvi adatokra épül, de további adalékként vonja be idősebb, falusi beszélők véleményét is. A szleng definíciójához hagyományosan a funkciók felsorolásával közelít a szakirodalom, és a kutatás e funkciók módosulásának és a nyelvi változás néhány külső okának a feltárásával figyelmeztet arra, hogy a hivatalos nyelvhasználatban is fel-felbukkanó szleng korántsem minden esetben a fiatalok nyelvi és/vagy kommunikációs (in)kompetenciájáról árulkodik, hanem a változó társadalom változó közösségi mentalitásának egy következménye. Ennélfogva pedig a szlenggel kapcsolatos pedagógiai gyakorlatot is érdemes lenne újragondolni.
Monitoring Mast Cell Populations in Waldenström’s Macroglobulinemia: A Xenotransplantation Study
Authors: Siskos Nikistratos , Bekiari Chryssa , Poutahidis Theophilos , Chadras Alexandros , Tsingotjidou Anastasia S.
Published: December 2019

Waldenström Macroglobulinemia (WM) is a B-cell lymphoproliferative disorder characterized mainly by uncontrolled accrual of M- immunoglobulin, secreted by malignant lymphoplasmatic cells. Mast cells interacting with malignant B-cells play an important role at the manifestation of the disease. Utilizing a previous xenotransplantation mouse model, this study evaluates long-term implant viability and quantifies distinct bone marrow mast cell populations along with their dynamics in non-WM and WM human bone implants.

Non-WM bone implants were obtained from the femoral head of adult humans undergoing hip arthroplasty or hemiarthroplasty, whereas WM human bone implants originated from bone biopsies obtained from the posterior iliac crest of patients with active WM. All bone particles were implanted intramuscularly in twenty-four NOD/SCID mice. Following 3, 4 or 8 months postoperatively, xenografts were removed and studied using special histological techniques to identify mature and immature mast cells.

Xenografts survived up to 8 months after implantation presenting normal cytoarchitecture (non-WM) or high-grade neoplastic infiltration and microresorption (WM bone biopsies). Statistical analysis of mast cell populations showed significant elevation regarding time progression and bone marrow microenvironment, thus suggesting the possible influence of malignant cells to the mast cell population in WM.

This study presents the extended survival of intramuscular implantation of human adult bone xenografts into NOD/SCID mice and provides additional information on the interaction between mast cells and malignant B-cells.

Published: December 2019

Ensinar ciências envolve obstáculos, sendo que, quando o tema suscita conflitos, o desafio é ainda maior. Esta pesquisa objetivou identificar quais são os principais obstáculos no aprendizado de um tema que gera conflito entre ciência e religião: a origem da vida. Os participantes da pesquisa foram 141 estudantes do IFBA de Simões Filho, que cursavam o 3º ano do Ensino Médio. Os alunos elaboraram dois mapas conceituais, que foram analisados qualitativamente. Foram identificados seis obstáculos: 1 – diferença entre a bagagem de conhecimento científico e religioso, 2 – divulgação de informações científicas erradas em meios de comunicação, 3 – confusões sobre o significado de teoria e lei, 4 – conhecimentos prévios equivocados, 5 – rejeição das teorias científicas por razões religiosas e 6 – postura cientificista de professores durante as aulas. O conhecimento científico pode contribuir para um pensar crítico, mas é essencial respeitar a diversidade sociocultural, como também seus contextos de aplicação, para assim se construir uma sociedade cada vez mais igualitária e justa.

Proceso migratorio, concentración escolar y resultados académicos en Cataluña
Authors: Bayona-i-Carrasco Jordi , Domingo Andreu
Published: December 2019

La concentración del alumnado inmigrante en las escuelas es vista con preocupación, ya que se relaciona generalmente con una mayor incidencia del fracaso escolar. En este contexto, y para Cataluña, se analiza la relación entre proceso migratorio, concentración escolar y resultados escolares para los alumnos que finalizan la educación secundaria obligatoria. Se emplea una perspectiva generacional, construida a partir del año de llegada a Cataluña, del lugar de origen y del de sus progenitores. Estos datos provienen del enlace realizado por el Instituto de Estadística de Cataluña entre los microdatos de los alumnos matriculados en escuelas públicas en el curso 2015-2016 y el Registro Estadístico de Población. Los resultados indican como la concentración se relaciona, para la mayoría de orígenes, con un incremento del fracaso escolar. Estos efectos se visibilizan a partir de elevados niveles de concentración, y son ambiguos en algunos orígenes, ya que no siempre se producen en el mismo sentido. Adicionalmente, estos efectos son más importantes para los alumnos autóctonos. La elevada diversidad de situaciones sugiere que la relación entre concentración y fracaso escolar no puede ser abordada desde una sola acción política.

Obesity is associated with polymorphisms of the fat mass and obesity associated gene (FTO). This meta-analysis aimed to investigate the association of the rs9930506 FTO gene polymorphism and obesity. To the best of our knowledge, this study is the first meta-analysis to evaluate the relation between FTO rs9930506 polymorphism and obesity.

We searched PubMed, Web of Science, and Embase to identify studies investigating the relations between the rs9930506 FTO gene polymorphism and obesity risk. We pooled adjusted odds ratios (OR) as overall and in continent subgroups. A Fixed-effects model was used to analyze the results of these studies in dominant and recessive models.

By examining 3337 obesity cases and 3159 healthy controls, we identified 8 eligible case-control studies. Considering the dominant model of inheritance, there was a relationship between the rs9939506 polymorphism and obesity (OR=1.34 [1.03- 1.74]). The association remained significant in the European subgroup (OR=1.68 [1.2-2.36]), but not in the Asian subgroup. Using the recessive model, we also found a significant relationship when the overall association was investigated (OR=2.47; 95% CI 1.56-3.91). In conclusion, this study identified that the carriers of the risk allele of FTO rs9930506 polymorphism are at higher risk for obesity.

The joint consensus panel of the European Atherosclerosis Society (EAS) and the European Federation of Clinical Chemistry and Laboratory Medicine (EFLM) recently addressed present and future challenges in the laboratory diagnostics of atherogenic lipoproteins. Total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDLC), LDL cholesterol (LDLC), and calculated non-HDLC (=total – HDLC) constitute the primary lipid panel for estimating risk of atherosclerotic cardiovascular disease (ASCVD) and can be measured in the nonfasting state. LDLC is the primary target of lipid-lowering therapies. For on-treatment follow-up, LDLC shall be measured or calculated by the same method to attenuate errors in treatment decisions due to marked between-method variations. Lipoprotein(a) [Lp(a)]-cholesterol is part of measured or calculated LDLC and should be estimated at least once in all patients at risk of ASCVD, especially in those whose LDLC declines poorly upon statin treatment. Residual risk of ASCVD even under optimal LDL-lowering treatment should be also assessed by non-HDLC or apolipoprotein B (apoB), especially in patients with mild-to-moderate hypertriglyceridemia (2–10 mmol/L). Non-HDLC includes the assessment of remnant lipoprotein cholesterol and shall be reported in all standard lipid panels. Additional apoB measurement can detect elevated LDL particle (LDLP) numbers often unidentified on the basis of LDLC alone. Reference intervals of lipids, lipoproteins, and apolipoproteins are reported for European men and women aged 20–100 years. However, laboratories shall flag abnormal lipid values with reference to therapeutic decision thresholds.
Exploring the optoelectronic properties of a chromene-appended pyrimidone derivative for photovoltaic applications
Authors: Assiri Mohammed A.
Published: December 2019

In the present study, a chromene-appended pyrimidone derivative (PBA) has been synthesized in order to account for the relationship between chemical structure and charge transport properties. The optical properties of PBA were studied in different solvents; it displays a weak emission profile in polar protic solvents but is highly emissive in polar aprotic solvents. Quantum chemical approaches on this molecule were performed in detail to highlight the importance of and to better understand the structural and electronic effects of introducing substituted pyrimidone rings in a polyaromatic molecule to support the development of new optoelectronic and photovoltaic devices. We shed light on the frontier molecular orbital, electron injection, electronic coupling constant, light harvesting efficiency, and photophysical properties of PBA by using density functional theory and time domain density functional theory. The absorption spectra (λa) and fluorescence emission spectra (λf) were computed in different solvents (Methanol, Ethanol, Butanol, Hexane, Chloroform and DMF) at the TD-B3LYP/6-31G** and TD-PBE/6-31G** levels of theory, and it was determined that the TD-B3LYP/6-31G** level is more accurate in the reproduction of experimental λa and λf in various solvents. Furthermore, no significant effect was observed on the λa and λf by changing the solvent polarity.
Umkämpfte Zeugenschaft
Authors: Alloa Emmanuel
Published: December 2019

The article focuses on a controversy between historians and psychoanalysts around the testimonial value of a Holocaust survivor (Serena N.). The survivor’s account of the Auschwitz uprising includes factual exaggerations, which has led historians to discard it. Psychoanalysts on the contrary stressed that the testimony accounted for something else: the possibility of resistance in the concentration camp, which gave the inmates hope in their struggle for survival. Survivors’ testimonies, so the argument, have both an epistemological and an ethical content. While philosophy’s insistence on the epistemological dimension of testimony has long generated a disregard for this ethical dimension, it would be equally wrong to construe a pure ethicality of testimony. Testimony is, first and foremost, an entangled social practice, which has tobe acknowledged in its agonal, its aporetic and its performative implications.
Monitoring bulk material pressure on bottom of storage using DEM
Authors: Žurovec David , Hlosta Jakub , Nečas Jan , Zegzulka Jiří
Published: December 2019

This article focuses on the experimental verification of a mathematical derivation of Janssen’s theory, which describes the distribution of pressures within the bulk material and pressure distribution on the walls of storage facilities. The experimental verification is performed in two ways. The first is the real measurement of the load transfer in a bulk material cylinder and the second is similar to the detection of the load transfer through simulations using the DEM method. The aim is to compare the results of the theoretical calculation according to Janssen’s theory with the real measurement and a simulation of exactly the same model situation. At the beginning of any design or optimisation of existing transport or storage facilities, the most important is the analysis of the bulk material in the form of measurements of mechanical-physical properties. The analysis methods used are also described here. The pressure at the bottom of a storage container between the methods used showed negligible differences. From this finding, it can be concluded that the DEM method is a very suitable means for verifying the design of transport and storage facilities. The simulations provide important information and insights that can also be used to optimise existing transport or storage facilities.

The backward problem of parabolic equations with the measurements on a discrete set
Authors: Cheng Jin , Ke Yufei , Wei Ting
Published: December 2019

The backward problems of parabolic equations are of interest in the study of both mathematics and engineering.
In this paper, we consider a backward problem for the one-dimensional heat conduction equation with the measurements on a discrete set.
The uniqueness for recovering the initial value is proved by the analytic continuation method.
We discretize this inverse problem by a finite element method to deduce a severely ill-conditioned linear system of algebra equations.
In order to overcome the ill-posedness, we apply the discrete Tikhonov regularization with the generalized cross validation rule to obtain a stable numerical approximation to the initial value.
Numerical results for three examples are provided to show the effect of the measurement data.

Comments on “New Concerns for Neurocognitive Function during Deep Space Exposures to Chronic, Low Dose Rate, Neutron Radiation”
Authors: Bevelacqua Joseph J. , Welsh James , Mortazavi S. M. Javad
Published: December 2019

Evaluations of the biological effects of space radiation must carefully consider the biological system response and the specific nature of the source term. Acharya et al. (2019) review neurocognitive function during deep space exposures to chronic, low dose rate, neutron radiation, but do not use a source term that reflects the actual space environment in terms of radiation types and their respective energies. In addition, important biological effects, including the adaptive response to the space radiation environment, are not addressed.
The effect of controlled reperfusion on experimental ovarian torsion

Published: December 2019

The objective of our research was to study the effect of controlled reperfusion on lactate and advanced oxidation protein products (AOPP) in experimental ovarian torsion (OT), and to evaluate the possibility to reduce the reperfusion injuries applying the ON-OFF technique of reperfusion. Material and Methods — Lactate and AOPP were measured in serum and ovarian homogenates of 70 females rats, divided equally into 7 groups: no intervention (nr. 1); laparotomy (nr. 2); 3 hours OT (nr. 3); 3 hours OT + 1 hour (nr. 4) or 24 hours (nr. 6) of simple reperfusion (SR); 3 hours OT + 1 hour (nr. 5) or 24 hours (nr. 7) of controlled reperfusion (ON-OFF). The results were analyzed using Welch's ANOVA. Results — OT produced an increase of serum (66%, p<0.001) and homogenate (38%, p=0.006) lactate, that tended to return to baseline in 24 hours despite the type of reperfusion. AOPP had grown in OT animals serum (20%, p=0.007) and homogenate (26%, p>0.05) and continued to rise in the serum after SR, while in ON-OFF technique groups – decreased by about 20% (p<0.01). Homogenate AOPP levels rised after reperfusion in all groups. Conclusion — Lactate is a biomarker for ischemia in OT. Increased AOPP in experimental groups indicates that there is a degree of oxidative stress that can affect the cells after the restoration of the blood flow. Therefore, the correct management of the condition that reduces reactive oxygen species production, such as controlled method of reperfusion, could be appropriate to prevent additional injuries.
Hybrid approach for treating patient with chronic thromboembolic pulmonary hypertension and extrinsic compression of left main coronary artery
Authors: Karabasheva Madina B. , Sagaydak Olesya V. , Matchin Yuriy G. , Mershin Kirill V. , Chazova Irina E.
Published: December 2019

Background ― Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare life-threatening form of pulmonary artery hypertension. CTEPH is potentially curable by performing surgical operation – pulmonary thrombendarteriectomy. Unfortunately, about 36% of patients with CTEPH are considered as inoperable because of different conditions including left main coronary artery compression syndrome (LMCS), caused by compression with delated pulmonary artery. Appropriate management of patients with CTEPH and LMCS remains unknown. Case report ― We report for the first time a case of a successful hybrid treatment of patient with CTEPH and LMCS. Due to high pulmonary vascular resistance (PVR) and LMCS (90% stenosis) the risk for pulmonary thrombendarteriectomy for patient was considered as high. The multidisciplinary team decided to start treatment with new method of treatment for patients with CTEPH – balloon pulmonary angioplasty. In 5 months 4 sessions of balloon pulmonary angioplasty were successfully performed. In a follow-up mean pulmonary artery pressure decreased from 57 to 37 mm Hg, PVR decreased from 20 to 7 WU. Coronary angiography showed no compression of left main coronary artery. The diameter of pulmonary artery decreased from 4.2 to 3.6 cm. Patient was reconsidered as operable and transferred to a surgical unit for pulmonary thrombendarteriectomy. Conclusion ― Effective balloon pulmonary angioplasty can lead to regression of left main compression syndrome in CTEPH patients. Balloon pulmonary angioplasty can be a “bridge-treatment” to pulmonary thrombendarteriectomy in patients with high operation risk.
HER-2/neu gene analysis on endoscopic biopsy samples and gastric resection materials in gastric carcinomas
Authors: Genc Ali Zisan , Koseoglu Resit Dogan , Arici Akgul , Demir Osman
Published: December 2019

Objective ― HER-2/neu assay in gastric cancers is routinely evaluated by immunohistochemistry and fluorescent in situ hybridization methods because the monoclonal antibody trastuzumab developed against HER-2/neu give rise to significant improving on the survival. In the HER-2/neu evaluation, some problems related to the sampling process, analysis method, tumor biology and heterogeinity are encountered. Our aim in the present study was to analyze these evaluation problems on endoscopic biopsy samples and resection materials of our cases with gastric carcinoma. Material and Methods ― The study included 109 gastric cancer cases. The analyses were realized on the resection materials of the 109 cases and the endoscopic mucosa biopsies of 43 out of these 109 cases. Immunohistochemistry was applied on mucosa biopsies and, tumor sections of resections, while fluorescent in situ hybridization was performed on tumor sections of resections (21 cases). The assays results were compared with each other and clinicopathological parameters. Results ― Our rate of HER-2/neu positivity (IHC3+ and IHC2+/FISH+ cases) was 6.42%. The compatibility rate between the rates of overexpression and amplification in resections was 90.5% while the compatibility ratio between the overexpression rates of mucosa samples and resections was 95.4%. The false negativity rate on mucosa biopsies was detected as 4.65%. HER-2/neu status was not correlated with unfavorable clinicopatological features. Conclusion ― Our gene positivity rate was near the lower limit of the range reported in the literature. Our compatibility rate between the results of immunohistochemistry and fluorescent in situ hybridization was over 90%. However our false negativity rate in mucosa biopsy analysis was low according to the literature. In order to preclude false negativity arising from tumor heterogeinity, we think that immunohistochemistry should be applied on the whole section.

Published: December 2019

Study purpose is to demonstrate the dynamics of mortality due to hepatic cirrhosis according to forensic medical autopsy data over the period from 2007 to 2016. Material and methods ― 268,139 protocols of forensic autopsies were studied to identify the number of deaths by hepatic cirrhosis over ten years between 2012 and 2016 and to determine the number of cases of liver failure associated with cirrhosis. To clarify the dynamics of mortality due to hepatic cirrhosis, a comparative analysis of two chronologically consecutive five-year periods, 2007-2011 and 2012-2016, has been conducted. The age of deceased by hepatic cirrhosis was studied. The number of cases with a histologically verified form of hepatic cirrhosis was specified. The average values and the percentage ratio of the number of examinations performed to the total number of all autopsies for non-violent death cases were calculated. Results ― Over ten years of study, death by hepatic cirrhosis was diagnosed 3,092 times, including 749 times with histologically confirmed liver failure. In 2009, there was an abrupt increase in mortality due to hepatic cirrhosis by the factor of 3.8, and the lowest mortality level was found in 2016. When comparing the mentioned two quinquennia, the first of them, 2007-2011, was characterized by an increase in the number of diagnosed hepatic cirrhosis. During the second one, 2012-2016, on the contrary, the dynamics of a decrease in the number of hepatic cirrhosis was revealed. At the average, the annual decrease in the number of hepatic cirrhosis diagnosed during the forensic medical examinations of corpses was 7.7%. The number of established cases of liver failure during the first five-year period compared with the data on the second one was significantly greater. In 2010, there were 109 such cases, in 2016 only 13. Among the histologically verified diagnoses, micronodular and mixed forms of hepatic cirrhosis prevailed. Most of the cases of hepatic cirrhosis were found in men aged within 31-40. Conclusion ― It has been found that over the past five years there has been a shift in the forensic-medical mortality values due to hepatic cirrhosis from the increasing trend to the decreasing one. If within the period of 2007-2011 an increase in diagnosed hepatic cirrhosis was observed, then during 2012-2016 a pronounced decreasing tendency in the number of such diagnoses was disclosed. During that time the number of histologically verified cases of hepatic failure decreased by 43.0%. As a cause of death, hepatic cirrhosis was more often recorded in men aged within 30–40.
Pulmonary tuberculosis in young people
Authors: dos Santos Vitorino Modesto
Published: December 2019

Tuberculosis is a global health problem and the main cause of death in the whole world. Young individuals are significantly affected in the low- and medium income countries. The children are more often infected by close contact with familiar adults at home, and lung tuberculosis with cavities plays a major role in environmental contamination. Their primary infection may evolve to primary tuberculosis without specific manifestations. The diagnostic challenges may be solved by higher clinical suspicion index associated with complementary investigation tools including tuberculin skin test and chest X-rays. These comments aim to enhance the awareness of lung tuberculosis at younger ages.

Signification as theoretical level for a structural difference between fiction and non-fiction
Authors: Amores Fúster Miguel
Published: December 2019

The expression of literary fiction is potentially unlimited. It could be said, like Searle, that potentially any text whatever can occur in fiction. By contrast, the contents of non-fictional discourses always have some kind of limits. Starting from this basic premise, this article will defend that the primary semiotic correlate that explains this difference can be found at the level of what Umberto Eco calls «signification» (that is, the culturally codified link that, within the sign, binds the planes of expression and content together). Thus, a theoretical structural difference between fiction and non-fiction is that in each case meaning is created following different signification logics. Whereas in non-fictional texts the signification link is governed by predetermined norms that arise from a series of real social and cultural interactions, in texts of literary fiction, which have no obligatory commitment to real world, this signification link is managed as if it were a potential in a virtually unlimited way.
El papel de los esquemas previos en la lectura
Authors: Giudici Fernández Beatriz
Published: December 2019

La lectura es una actividad compleja dominada por el cerebro humano en la que juegan un papel primordial los esquemas mentales previos. Al leer se activan simultáneamente una serie de esquemas o «pantallas», que se activan/desactivan sucesivamente a medida que el lector acepta o rechaza las opciones que se le presentan. Varios esquemas se mantienen abiertos al mismo tiempo, a la par que otros se cierran, recomponen o descartan. Es posible que la teoría de los esquemas arroje luz sobre un proceso en el que la vista, la memoria, el reconocimiento, la experiencia, las lectura previas, etc., tienen un papel primordial a la hora de descifrar un texto, es decir, de leer.
Richard Wagemese's Indian Horse: Stolen Memories and Recovered Histories
Authors: Miroux Franck
Published: December 2019

Este artículo pone de manifiesto las estrategias narrativas mediante las cuales el autor anishinaabe canadiense Richard Wagamese somete al lector de su novela Indian Horse (2012) a la misma violencia sufrida por el joven héroe cuando la repentina resurgencia del recuerdo traumático reprimido acaba rompiendo la linealidad aparente de su historia. Asimismo, este estudio pretende demostrar que la reapropiación de la memoria robada, y por la tanto la posibilidad de reconstruirse tras el traumatismo vivido, pasan por una reapropiación de las formas aborígenes del relato gracias a las que Wagamese contribuye de manera significativa a la reescritura de la historia de las escuelas residenciales autóctonas de Canadá. This paper purports to explore the narrative devices which enable the Anishinaabe Canadian author Richard Wagamese to compel the reader of his novel Indian Horse (2012) to experience the same violence as that faced by the young protagonist when the repressed memory of the terrible abuse suffered at an Indian residential school resurfaces decades after, disrupting the apparently linear course of the story. This study also seeks to show that Wagamese offers a major contribution to the rewriting of the history of residential schools in Canada by reclaiming Aboriginal narrative forms as a means to recover stolen memories, and thus to reconstruct both the fragmented (his)story and the shattered self.
Reinventando la política, género y sociedad en la cultura victoriana: un enfoque desde la retórica cultural
Authors: Cortes-Ramirez Eugenio-Enrique
Published: December 2019

La Retórica Cultural es el instrumento con el que la cultura hace que la sociedad se reinventa a si misma a través del lenguaje. En la Cultura Victoriana, la lucha por ser representado supuso una mirada al futuro desde un regreso al mundo clásico mediante la actualización de la Retórica. En otras palabras, el interés por las antiguas sociedades de Asia y el Mediterráneo había sido despertado en el seno de la Sociedad Victoriana. En ese proceso de actualización, la Retórica Cultural logra un nuevo intento de aproximación a los conceptos de Política, Género y Sociedad. Por esta razón, la Retórica Cultural consigue ser ese instrumento específico con el que se realizan nuevas aceptaciones culturales en el seno de la Sociedad Victoriana.

Hallamos bellos exponentes en su aplicación a diferentes géneros y ramas artísticas, así como en diversas épocas. A partir de los estudios clásicos de reconocidos teóricos como Lucien Dällenbach, Gérard Genette o Mieke Bal, y del análisis de un corpus de obras que abarca distintas artes y géneros (desde la pintura hasta el cine, el teatro, la novela, el relato y la lírica), este artículo ofrece una tipología que permite clasificar cada uno de los casos propuestos, a pesar del amplio abanico de matices que se despliega en ellos.
Modeling Baltic market benchmark index: a comparison of models
Authors: Belovas Igoris
Published: December 2019

In this paper we perform a statistical analysis of the returns of OMX Baltic Benchmark index. We construct symmetric α-stable, non-standardized Student’s t and normal-inverse Gaussian models of daily logarithmic returns of the index, using maximum likelihood method for the estimation of the parameters of the models. The adequacy of the modeling is evaluated with the Kolmogorov-Smirnov tests for composite hypothesis. The results of the study indicate that the normal-inverse Gaussian model outperforms alternative heavy-tailed models for long periods of time, while the non-standardized Student’s t model provides the best overall ﬁt for the data for shorter intervals. According to the likelihood-ratio test, the four-parameter models of the log-returns of OMX Baltic Benchmark index could be reduced to the three-parameter (symmetric) models without much loss.

Direct and inverse factorization algorithms of numbers
Authors: Melničenko Grigorijus
Published: December 2019

The factoring natural numbers into factors is a complex computational task. The complexity of solving this problem lies at the heart of RSA security, one of the most famous cryptographic methods. The classical trial division algorithm divides a given number N into all divisors, starting from 2 and to integer part of √N. Therefore, this algorithm can be called the direct trial division algorithm. We present the inverse trial division algorithm, which divides a given number N into all divisors,starting from the integer part of √N to 2.

Modeling of Pulse Propagation Factor Changes in Type II Second Harmonic Generation
Authors: Kurtinaitis A. , Dementjev A. , Ivanauskas F.
Published: December 2019

We describe the simulations of the second harmonic generation of ultrashort laser pulses by numerically solving a system of wave propagation equations. The equations are solved by using a split-step method in twodimensional cyllindrically symmetric space and time coordinates. The diffraction part of a solution uses the Hopscotch type finite-difference scheme on a regular grid. The transport part is solved by using the cubic spline approximation. The obtained numerical results satisfactorily respect energy conservation constraints.

The algorithm and program developed make it possible to optimize the process of the second harmonics generation and to identify the conditions where sufficiently high degree of the pulse compression with a relatively low degradation of their quality is achieved.
Boolean Discriminant Functions in Symbolic Learning with Subclasses
Authors: Raškinis A. J.
Published: December 2019

Finding methods to increase the complexity of the Boolean discriminant functions and to stay within the limits of tractability set by combinatorics is an important task in the field of symbolic machine learning. The original formalism based on meta-features is introduced. Meta-features are predicates that describe relations between the features of the investigated objects and the subclasses (clusters inside classes) of the training set. The formalism facilitates finding Boolean discriminant functions of three variables. These are more complecated than simple conjunctions if the partition of the original training set into subclasses is given. The structure of meta-feature predicates is close to the structure of statements used by domain experts to describe their knowledge. Consequently, the formalism can be applied in hybrid learning systems, which incorporate information obtained from domain experts.

Hypothesis on the Solvability of Parabolic Equations with nonlocal Condition
Authors: Sapagovas Mifodijus
Published: December 2019

Numerous and different nonlocal conditions for the solvability of parabolic equations were researched in many articles and reports. The article presented analyzes such conditions imposed, and observes that the existence and uniqueness of the solution of parabolic equation is related mainly to ”smallness” of functions, involved in nonlocal conditions. As a consequence the hypothesis has been made, stating the assumptions on functions in nonlocal conditions are related to numerical algorithms of solving parabolic equations, and not to the parabolic equation itself.
Design of Multi-Dimensional Recursive Systems through Pad'e Type Rational Approximation
Authors: Vavilov Valeri V. , Tchobanou Mikhail K. , Tchobanou Peter M.
Published: December 2019

The results obtained in classical 1-D rational approximation are extended in this paper to rational approximation of M-D functions. A full analog of classical Montessus de Ballore theorem for the convergence of the rows of Pad´e’s tables is obtained. It is shown that the appropriate theorem for uniform convergence in C2 will really take place only in the case of choosing the necessary determinative (interpolation) sets Ij(n,m), j = 1, 2. This theorem allows us to handle the problem of deriving the transfer function of a M-D digital system, that is described by its state-space representation1. The results of computer modelling by using MATLAB software are presented. Both the convergence theorem and results of modelling show that from theoretical and practical points of view the proposed approach is promising.

Electrical Anisotropy of Thin Metal Films Growing on Dielectric Substrates
Authors: Jakučionis L. , Kleiza V.
Published: December 2019

Electrical properties of conductive thin films, that are produced by vacuum evaporation on the dielectric substrates, and which properties depend on their thickness, usually are anisotropic i.e. they have uniaxial anisotropy. If the condensate grow on dielectric substrates on which plane electrical field E is created the transverse voltage U⊥ appears on the boundary of the film in the direction perpendicular to E. Transverse voltage U⊥ depends on the angle γ between the applied magnetic field H and axis of light magnetisation. When electric field E is applied to continuous or grid layers, U⊥ and resistance R of layers are changed by changing γ. It means that value of U⊥ is the measure of anisotropy magnitude. Increasing voltage U0 , which is created by E, U⊥ increases to certain magnitude and later decreases. The anisotropy of continuous thin layers is excited by inequality of conductivity tensor components σ0 ≠ σ⊥. The reason of anisotropy is explained by the model which shows that properties of grain boundaries are defined by unequal probability of transient of charge carrier.
