Signum et gens – Zur Gendersemiotik in Clara und Robert Schumanns Liederzyklus Liebesfrühling
Authors: Link Martin
Published: October 2020

The marriage between Clara and Robert Schumann is one of the most popular relationships in music history. In 1840, a song cycle named Liebesfrühling with songs from Clara Schumann as well as from her husband was collectively published under their names. Despite the fact that the married couple did not specify the voice register and gender of the vocal parts within the score, some hints indicating the gender of the personas can be found for instance in the personal pronouns of the text. Yet, some parts of the song cycle do not provide such clues, leaving the question, to which gender the vocal parts are ascribed, completely open. Nevertheless, some scholarly examinations like Melinda Boyd’s publication Gendered voices. The “Liebesfrühling” Lieder of Robert and Clara Schumann try to answer this question using semiology as a method to indicate gender assignments. However, this raises the question of how far gender aspects can be examined through semiotic approaches. What symbols are used to specify gender? Did this change in history? And can these ascriptions be found in the music of Clara and Robert Schumann? The chosen method will show difficulties because of its time-constraint and the problem of relevancy. This is why the proposed theses of Boyd will be inspected regarding the text and the score of the song cycle Liebesfrühling. At the same time, the investigation will try to consider the importance of contemporary performance practice.
Die Leiden der jungen Clara: Das Klaviertrio Opus 17 als Ausdruck einer Neu-Romantikerin
Authors: Reichwald Siegwart
Published: October 2020

Two reasons precipitated the move of the Schumanns to Dresden: Robert Schumann’s health and the reconciliation with Clara Schumann’s father. Yet Dresden quickly turned into disappointment: Robert’s mental condition worsened, relations with her father deteriorated. Burdened with familial responsibilities and no time for concert tours, Clara found expression in her most ambitious and melancholic composition, creating one of the most individualistic and innovative chamber works of her generation. Central to this narratological reading is the composer’s use of the Clara theme (diatonically descending fifth) and its many derivatives throughout the work. Substantial revisions found in the autograph (RSH 12897-A1) present obvious clues about overarching thematic and harmonic strategies and early reviews emphasizing the composer’s individualistic voice offer further hermeneutic insights. To express her disappointing Dresden experience defiantly, Clara explored the possibilities of thematic integration among all four movements as well as a super-imposed sonata form design across the whole work.
Johann Nepomuk Hummels Sonate in fis-Moll Op. 81 – Studien zu Entstehungshintergrund, Rezeption und formaler Struktur
Authors: Tiemeyer Daniel
Published: October 2020

The article examines the significance of one of Johann Nepomuk Hummel’s masterpieces. First, it highlights the circumstances of its production and the contemporary critical acclaim in the AmZ. In a second step, Robert Schumann’s involvement with this work is shown. In his journal, the sonata of Hummel is mentioned several times which indicates the engagement of the young piano discipline. In a short article, published in the NZfM in the year 1839, Schumann links this sonata with the compositional “way of Mozart” and thus gives an important hint to the formal design of the piece itself. Aspects of formal organization and structure of this sonata are analyzed and presented in the third part of the essay. In opposition to Beethoven’s motivic development, Hummel pursues another strategy of formal structure by stringing together each of the segments and themes. Thus, the focus shifts from a dynamic design of sonata-form to a more epic layout of the piece. Additionally, technical development and innovations concerning piano techniques and virtuosity are examined.
Organic Molecules with Inverted Gaps between First Excited Singlet and Triplet States and Appreciable Fluorescence Rates

Published: October 2020

One of the recent proposals for the design of state-of-the-art emissive materials for organic light emitting diodes (OLEDs) is the principle of thermally activated delayed fluorescence (TADF). The underlying idea is to enable facile thermal upconversion of excited state triplets, which are generated upon electron-hole recombination, to excited state singlets by minimizing the corresponding energy difference resulting in devices with up to 100% internal quantum efficiencies (IQEs). Ideal emissive materials potentially surpassing TADF emitters should have both negative singlet-triplet gaps and appreciable fluorescence rates to maximize reverse intersystem crossing (rISC) rates from excited triplets to singlets while minimizing ISC rates and triplet state occupation leading to long-term operational stability. However, molecules with negative singlet-triplet gaps are extremely rare and, to the best of our knowledge, not emissive. In this work, based on computational studies, we describe the first molecules with negative singlet-triplet gaps and considerable fluorescence rates and show that they are more common than hypothesized previously.
Mechanism of Covalent Binding of Ibrutinib to Bruton’s Tyrosine Kinase revealed by QM/MM Calculations
Authors: Voice Angus , Tresadern Gary , Twidale Rebecca , Van Vlijmen Herman , Mulholland Adrian
Published: October 2020

Ibrutinib is the first covalent inhibitor of Bruton’s tyrosine kinase (BTK) to be used in the treatment of B-cell cancers. Understanding the mechanism of covalent inhibition is crucial for the design of safer and more selective covalent inhibitors that target BTK. There are questions surrounding the precise mechanism of covalent bond formation in BTK as there is no appropriate active site residue that can act as a base to deprotonate the cysteine thiol prior to covalent bond formation. To address this, we have investigated several mechanistic pathways of covalent modification of C481 in BTK by ibrutinib using QM/MM reaction simulations. The lowest energy pathway we identified involves a direct proton transfer from C481 to the acrylamide warhead in ibrutinib, followed by covalent bond formation to form an enol intermediate. There is a subsequent rate-limiting keto-enol tautomerisation step (DG‡=10.5 kcal mol-1) to reach the inactivated BTK/ibrutinib complex. Our results represent the first mechanistic study of BTK inactivation by ibrutinib to consider multiple mechanistic pathways. These findings should aid in the design of covalent drugs that target BTK and related proteins.
Reduced Scaling Formulation of CASPT2 Analytical Gradients Using the Supporting Subspace Method
Authors: Song Chenchen , Neaton Jeffrey B. , Martínez Todd J.
Published: October 2020

We present a reduced scaling and exact reformulation of state specific CASPT2 analytical gradients in terms of the MP2 and Fock derivatives using the supporting subspace method. This work follows naturally from the supporting subspace formulation of the CASPT2 energy in terms of the MP2 energy using dressed orbitals and Fock builds. For a given active space configuration, the terms corresponding to the MP2-gradient can be evaluated with O(N5) operations, while the rest of the calculations can be computed with O(N3) operations using Fock builds, Fock gradients, and linear algebra. When tensor-hyper-contraction is applied simultaneously, the computational cost can be further reduced to O(N4) for a fixed active space size. The new formulation enables efficient implementation of CASPT2 analytical gradients by leveraging existing GPU-based MP2 and Fock routines. We present benchmark results that demonstrate the accuracy and performance of the new method. Example applications of the new method in ab initio molecular dynamics simulation and constrained geometry optimization are given.

Published: October 2020

In this paper, we developed the fabrication of a plasmonic near-perfect absorber with a dense, uniform monolayer of AuPd alloyed nanoparticles as the absorbing layer. The nanoparticles were prepared by dewetting thin films (<4 nm) of each metal on a dielectric surface and extensive characterization confirmed the lack of other bimetallic phases. Plasmonic near-perfect absorbers containing an alloyed nanoparticle layer demonstrated both strong on-resonance absorption of incident light (up to 97%) and an improved photocatalytic response, compared to either monometallic derivative, for the photoelectrochemical reduction of water.
Sixties from Archaeology. Irkutsk School
Authors:   Irkutsk State University, Berdnikova N. E.
Published: October 2020

The Sixties is a specific sociocultural phenomenon of Russian (Soviet) history. This term refers to the post-war era of the mid-1950s – late 1960s, and means the generation of the Soviet intelligentsia, born approximately between 1925 and 1945s and formed by them subculture. This concept is used to assess the phenomena and changes associated with literature, art, social processes. Special assessments of this phenomenon in science have not been available yet. Some postmodern approaches are used in the study of sociocultural phenomena during studying the phenomenon of the “sixties” in archeology including the identification of certain cultural concepts and sociopsychological determinants, consideration of the integrity of the phenomenon through the analysis of individual parts in order to provide opportunities for self-identification. The factual base of this article consists of publications, personal knowledge and impressions of the author. After the “defeat” of the Petri’s Irkutsk archaeological school in the 1930s, and until the mid-1950s. archaeology at Irkutsk State University was in a flickering state. Since mid-1950s began the Renaissance of the Irkutsk archaeological school. The dotted lines of connections from the Petri school through his scholarly M. M. Gerasimov and the “guardians” of traditions of N. A. Florensov and S. V. Shostakovich associated with the Petri school were realized in the formation of a team of young researchers and the creation of a stable system of scientific archaeological research at the Irkutsk University. The activities of the new generation of the Irkutsk archaeological school were expressed in field researches, in the development of methods, approaches and concepts, in publication activity, in international relations, in the creation of corporate entities as special structures and training systems. This activity reflects all sociopsychological determinants and cultural concepts that are characteristic of the generation of the sixties in different areas of the existing Soviet society. The nature of this activity can be defined as a new “discovery” of Siberia - archaeological. This activity formed the basis for the development of archaeological science at Irkutsk State University, the implementation of which is ongoing today.
Olov Khamnigans in the 19th Century: Ethnic Composition and Allocation
Authors:   Institute for Mongolian, Buddhist and Tibetan Studies SB RAS, Nanzatov B. Z. , Sodnompilova M. M. ,   East-Siberian State Institute of Culture
Published: October 2020

This article continues the series of the works devoted to the study of the ethnic composition of the Buryat and Khamnigan departments of the 19th century. One of the self-government bodies of indigenous of the Transbaikal in the 19th century was the Urulginskaya Steppe Duma, the main population of which was the Tungus of the Manchu tribe, as they were characterized by the Russian administration. One of the boards of this Duma was the Olovskaya indigenous Council. The department is of particular interest in terms of the ethnic composition of its population and its origin. The ethnic composition of the Urulga Steppe Duma revealed the extensive contacts of the Upper Amur – Shilka population with the vast area of the Transbaikal-Amur subregion, including the territories of Inner Asia, North Asia and Amur region. Different groups of horse and deer Tungus, on the one hand, and various groups of the Mongolian population, including the Khingan Mongols, Daurians and Buryats, on the other hand, took part in its formation. Also more ancient contacts of the Tungus with the Yukagirs were found. The composition of the Urulga Steppe Duma initially included five indigenous authorities. One of them was the Olovskaya indigenous Authority (Uprava). The Khitan, and subsequently Daurian population, which came into close contact with both the Tungus-Manchu tribes and the Bargy-Buryat groups of the population, created a special layer of the population – Khamnigan people. However, in Russian documents the entire population of the Urulga Steppe Duma, a part of which also was the Olovskaya indigenous Authority (Uprava) recorded as Tungus. The ethnic composition of the Olov Khamnigans shows that the population of the upper Amur – Shilka, has incorporated various ethnic elements not only from the Middle Ages, but also from antiquity. The article suggested the authors’ vision of origin of ethnonyms of the population of authority and their development. A number of ethnonyms such as Duligar, Bayagir, Kylteger discovers the presence of the Tungusic and Mongolic strata in the face of Khamnigan-Mongols, Daurs, Buryats. The Mongolic stratum is also represented by the bearers of the ethnonym Üzön, which has analogies in eastern and central Mongolia, among the Selenga Buryats and among the Kipchak tribe, which is part of the Kazakhs of Middle Juz. A detailed map of the settlement of the Olov Khamnigans was compiled, based on the census tables.
Modern Burkhanism through the History in the Ritual Life of the Altai People
Authors:   Gorno-Altai State University, Tadina N. A.
Published: October 2020

The article is devoted to the urgent problem of the revived Burkhanism formation in the Altai Republic. The authors came to the conclusion that the historical path of Burkhanism from the ban to the post-Soviet rehabilitation led it to the ambiguous comprehension. The main theories about Burkhanism given in the reports of the scientific conference held in the year of its one hundredth anniversary are highlighted. It is noted that modern Burkhanism is supported by the southern Altai people, namely the Altai-Kizhi that live in the Burkhanism places of the Ongudai and Ust-Kan regions of the Altai Republic. Against the background of the revival of the Oyrot heritage, the post of Zaisan as head of a clan, the confrontation between the adherents of Altai jan (Altai faith), that represent a mixture of “old” Burkhanism and Shamanism, and a group of Altai Buddhists, who interpret Burkhanism as the periphery of Lamaism, appeared. Based on the ethnographic data the ritual practice of «feeding» the fire of the hearth, sprinkling sacred objects with milk and cleansing by fumigation with juniper are represented, which expresses the key idea of Burkhanism ‒ the reverence of the upper heavenly world that gives life to man, the well-being to his family and his clan. It was revealed that Burkhanism consolidated the people spiritually and ethnically; therefore, observance of ritual symbolism in everyday life contributes to the preservation of the life values: peace, grace, happiness, luck. In ritual life, Burkhanism symbols and attributes are observed spatially and temporarily. The period of the young moon and sunrise, as well as the time of the birth of the sun (day), are considered the most “favorable” time to initiate ceremonies in honor of the living. Ritual actions are performed according to the sun and an even number of times. Everything connected with the “world of the living” honoring ritual should be white. The very existence of the world depends on proper observance. According to the norms of modern Burkhanism, it is considered that the one who observes the ritual symbolism approved by Burkhanism is one of the «True» Altaians and this certain standard of “Altai” based on the traditional worldview.
Regarding the Transcript of a Lecture Course by G. F. Debets at the Department of Anthropology of the Moscow State University in 1954
Authors:   Institute of Ethnology and Anthropology RAS, Gerasimova M. M.
Published: October 2020

The subject of this study was a poorly readable 66 years old typewritten text. This is a transcript of twenty lectures by the outstanding Russian anthropologist Georgy Debets (1905–1969), a record of his training course “Anthropology of the Peoples of USSR”. In 1954, he taught it at the Department of Anthropology at Moscow State University. Initially G. F. Debets had intended to write a textbook based on this lectures, but he did not fulfill this idea. The characteristics of the training course are given in general terms. The main attention is paid to how G. F. Debets saw the history of anthropological study of the peoples of Russia. At the same time, certain changes were taken into account both in the theory and practice of anthropological studies that have taken place since the early 1950s. The 1st lecture was delivered on September 6th, 1954, the last lecture was dated to the end of December of the same year. The lecture transcripts are mainly 30–40 pages long, with the exception of lectures on the peoples of Kazakhstan and Central Asia, which fit in 50 pages. The first two lectures were devoted to the study of the history of the peoples of the USSR from ancient antiquity to the present, the 3–5th lectures dealt with the methodology of studying the modern and fossil population, meaning racial somatology and craniology. The 6th lecture outlined the principles of the classification of modern human races and described the various existing classifications. Five lectures (7–11th) were devoted to the review of the country's population paleoanthropology from the Paleolithic era until the Middle Ages, inclusive. The next nine lectures covered the anthropology of peoples living in separate geographical areas. G. F. Debets pointed that the course he taught was not about the history of Russian anthropology, so he would not touch on many works of the 19th century. The first lectures outline the stages of development of anthropological research of the peoples of the USSR and state the results of isolated stages, which are reflected unevenly. Both this periodization and the characteristics of the stages do not always coincide with the periodization that was presented in the university textbooks of anthropology that appeared later. For this reason, the transcript of lectures of 1954 is a valuable source both for the history of physical anthropology as a whole and for understanding the scientific views of one of the founders of modern anthropology.
Toward Buryat-Yakut Ethnic Connections: İgidäi and Eχirid
Authors:   Institute for Mongolian, Buddhist and Tibetan Studies SB RAS, Nanzatov B. Z. , Tishin V. V. ,   Institute for Mongolian, Buddhist and Tibetan Studies SB RAS
Published: October 2020

The formation of the Yakut people is associated with the several waves of migration from the southern direction, in which Mongol-speaking communities took part. The researchers of the Yakuts ethnic history noticed the ethnonym İgidäi, known as the name of a large tribal group in the interfluve of Aldan and Lena Rivers, in the 17th century, which was connected in Russian written sources with the particular unit are “Igideiskaya volost”. In the late 19th century the descendants of this population were presented by four administrative units (nasleg) in the Bayagantai and Baturus ulus (as 1st and 2nd Igideysky in both cases). There is no association in the names of the smaller administrative units (Russian: rod) attested as parts of these nasleg with other ethnonyms. This suggests that those populations were quite homogeneous and did not subject to large external migrations in the historical period. By itself, the ethnonym İgidäi was repeatedly associated with the name of a large tribal grouping of Western Buryats, known as eχirid (rus. ekhirit), which in turn goes back to the Middle Mongolian ethnonym Ikires. Pprevious researchers had outlined right path of searching, however they limited only a statement of the formal consonance of the Yakut İgidäi and buryats eχirid. The present article is devoted to the argumentation of the comparison based on the analysis of phonetic data. The form İgidäi make it possible to reconstruct the primary appearance of the ethnonym as *ikir (plur.: ikid), which correlates with the dialectal version of the Western Buryat ethnonym attested as eχirši, also referring to the early form *ikir. The tribe Ikires mentioned above was known in the 13–14th centuries and was associated with the territory of Mongolia. Information about the Ekhirits, because of lack of written sources, attested only in the 17th century AD in the Western Baikal region. Despite the obvious kinship of their names, it is not possible to trace any intermediate stages that would allow us to talk about the unity of the history of the population known by these ethnonyms. At the same time, the identification among the Yakuts the ethnonym, which clearly goes back to the form that demonstrates the phonetic characteristics of Western Buryat dialects, allows us, based on the general historical context, to move the lower chronological border beginning the stay of the ethnonym Eχirid carriers in the Western Baikal region at least by a century.
A Hybrid GA-PSO Method for Evolving Architecture and Short Connections of Deep Convolutional Neural Networks
Authors: Wang B , Sun Y , Xue Bing , Zhang Mengjie
Published: October 2020

© 2019, Springer Nature Switzerland AG. Image classification is a difficult machine learning task, where Convolutional Neural Networks (CNNs) have been applied for over 20 years in order to solve the problem. In recent years, instead of the traditional way of only connecting the current layer with its next layer, shortcut connections have been proposed to connect the current layer with its forward layers apart from its next layer, which has been proved to be able to facilitate the training process of deep CNNs. However, there are various ways to build the shortcut connections, it is hard to manually design the best shortcut connections when solving a particular problem, especially given the design of the network architecture is already very challenging. In this paper, a hybrid evolutionary computation (EC) method is proposed to automatically evolve both the architecture of deep CNNs and the shortcut connections. Three major contributions of this work are: Firstly, a new encoding strategy is proposed to encode a CNN, where the architecture and the shortcut connections are encoded separately; Secondly, a hybrid two-level EC method, which combines particle swarm optimisation and genetic algorithms, is developed to search for the optimal CNNs; Lastly, an adjustable learning rate is introduced for the fitness evaluations, which provides a better learning rate for the training process given a fixed number of epochs. The proposed algorithm is evaluated on three widely used benchmark datasets of image classification and compared with 12 peer Non-EC based competitors and one EC based competitor. The experimental results demonstrate that the proposed method outperforms all of the peer competitors in terms of classification accuracy.

Phosphate Enema Causing Life-Threatening Rectal Perforation
Authors:   Department of Clinical Surgical Sciences The University of the West Indies, Eric Williams Medical Sciences Complex, Mount Hope, Trinidad, West Indies.
Published: October 2020

We report a near fatal rectal perforation due to a phosphate enema in an elderly male. The presentation in septic shock within 4 hours of the enema is quite rare. Early recognition and prompt management are essential for a good outcome. A defunctioning colostomy is standard for these cases but we recommend a distal rectal washout since intraluminal faeces in a loaded rectum could be a cause of ongoing sepsis. Although enemas are commonly used for constipation in the elderly, suppositories and oral preparations should be used preferentially where appropriate.

Published: October 2020

Morocco, home to nearly 36 million inhabitants has undergone demographic and epidemiological transitions over the past 50 years. Alongside this transition is the prevalence of Non-Communicable Diseases (NCDs) which has also risen substantially and has contributed remarkably to the rise in the population's need for healthcare services. In order to respond to the increasing healthcare needs of the Moroccan population, it is necessary to ensure that healthcare providers are readily accessible and sufficient. As one of the most accessible healthcare providers, pharmacists are well positioned to address these demands. It is therefore essential to build a competent pharmaceutical workforce in Morocco with a specialized focus on pharmacy education and training. However, the education and training of pharmacy students in the country has been grossly disrupted by the present COVID-19 pandemic. In this paper, we examine the impact of the COVID-19 pandemic on pharmacy education in Morocco. The net impact of this unprecedented pandemic on pharmacy education in Morocco has become well pronounced with a lot of accompanying challenges. If not addressed, the results in the long-run may be devastating. Doi: 10.28991/SciMedJ-2020-02-SI-8 Full Text: PDF

MODELLING OF ENVIRONMENT SENSORS BASED ON THE SURFACE PLASMON RESONANCE EFFECT
Authors: Vasilevskiy M.
Published: October 2020

Surface plasmons (SPs) are collective excitations of free electrons in a conducting medium bounded by a surface or interface with a dielectric. They can originate surface plasmon-polaritons (SPPs), which are evanescent waves involving electron density oscillations and the associated electromagnetic (EM) field whose amplitude decays exponentially with distance from the surface. SPPs are characterised by a dispersion curve (frequency vs wavevector along the interface) that lies outside of the light cone, so they cannot be excited directly by propagating light; however, it is possible to excite them using the Attenuated Total internal Reflection (ATR) method or a periodic grating. SPs in a confined geometry such as a metallic sphere are localised in space and characterised by discrete frequencies (a single one in the case of sphere, two or three in the case of an ellipsoid). They can be excited directly by propagating light if its frequency coincides with the localised SP frequency, giving rise to the Localized Surface Plasmon Resonance (LSPR). Both SPPs and LSPR are highly sensitive to the dielectric constant of the surrounding media and can be used for environment sensing (e.g. gas molecules that adsorb onto the structure’s surface).

Participated in the study 5 (five) students of the 3rd year of High School of a public school in Amapá, located on the border of Brazil/French Guiana, which has the French language as a mandatory curricular component. Specifically, on the production of the data, semi-structured interviews were used. The results of the research show that it is necessary to think about linguistic policies that value the teaching of languages with a focus on culturally marked proposals, which are based, above all, on the relationship between language and culture. In addition, the meanings produced, from the speeches of the investigated students, are demonstrative that, for these students, the learning of the French language mediates not only frank communication but also the learning of the elements of French culture.

Published: October 2020

El ciberacoso es un problema actual, presente en la población adolescente, que tiene consecuencias negativas en la vida de los jóvenes. En este estudio se pretende estimar y contrastar un modelo de efectos directos e indirectos de la Cibervictimización en adolescentes de Nivel Medio Superior que integre variables Personales (Autoestima, Malestar Psicológico, Reputación Social) y Contextuales (Comunicación Familiar, Funcionamiento Familiar, Clima Social en el Aula y Adicción a Redes Sociales). Se aplicaron las escalas de Victimización Virtual (Buelga, Cava y Musitu, 2012), AF-5 (García y Musitu, 1999), Malestar Psicológico (Kessler & Mroczek, 1999), Reputación Social (Caroll, Houghton, Hattie, & Durkin, 1999), Comunicación Familiar (Barnes & Olson, 1982, 1985), Funcionamiento Familiar (Smilkstein, Ashworth, & Montano, 1982), Clima Social en el Aula (Moos, Moos & Trickett, 1984) y Adicción a Redes Sociales (Peris, Maganto, & Garaigordobil, 2018) a una población de 1306 adolescentes de un plantel educativo ubicado en el noreste del estado de Nuevo León. Los resultados preliminares, correspondientes al primer objetivo específico del estudio, y obtenidos a través de un análisis de correlación de Pearson, muestran que las variables personales y contextuales están relacionadas de forma significativa con la victimización virtual de los jóvenes. Dicho hallazgo resalta la importancia de tomar en cuenta a la familia y la escuela en las líneas de acción preventivas y de intervención de la problemática.

Flaş Elektroretinogram sinyalleri gözün retina tabakasının flaş bir ışık ile uyarılması sonucu ortaya çıkan elektriksel potansiyellerdir. Bu sinyale ait iki temel bileşeni olan ‘a’ ve ‘b’ dalgaları retina tabakasının değerlendirilmesinde önem arz etmektedir. Bunun için farklı sinyal işleme tekniklerinden yararlanılmaktadır. Yapılan bu çalışmada sağlıklı bireylerden kaydedilen flaş Elektroretinogram sinyallerinin rod, maksimum kombine ve kon yanıtları kullanılarak Kısa Zamanlı Fourier Dönüşümü ve Sürekli Dalgacık Dönüşümü yöntemleriyle sinyallerin ‘a’ ve ‘b’ dalgaları analizi edilmiştir. Bu doğrultuda dalgaların lokasyonlarının tespit edilmesinde hangi yöntemin daha başarılı olduğu irdelenmiştir. Gerçekleştirilen analizler sonucunda her üç yanıtta da dalgaların analizi için Sürekli Dalgacık Dönüşümünün daha başarılı bir yöntem olduğu tespit edilmiştir. Bunun yanı sıra Sürekli Dalgacık Dönüşümünde rod ve kon yanıtları için Coiflet, Gauss, Meksika şapka ve Morlet dalgacıklarının, maksimum kombine yanıtı için ise Morlet dalgacığının kullanılması halinde dalgaların lokasyonlarının daha doğru bir şekilde tespit edebileceği saptanmıştır.

Published: October 2020

Temel anlamda optimizasyon, bir veya birden fazla problemin belirli koşullar altındaki en iyi çözümlerini bulma işlemidir. Günümüzde bu problemlerin çözümü için klasik yöntemler ve sezgisel yöntemler kullanılmaktadır. Sezgisel yöntemlerden biri olan Rüzgar Güdümlü Optimizasyon algoritması, rüzgarın atmosfer içerisindeki hareketini temel alarak atmosferik dinamik eşitlikten yararlanan tek amaçlı optimizasyon problemlerine çözüm arayan bir algoritmadır.Bu çalışmada çok-amaçlı optimizasyon problemlerinin çözümü için Rüzgar Güdümlü Optimizasyon algoritması yeniden düzenlenmiştir. Çok-amaçlı optimizasyon problemlerinde elde edilen sonuçların gerçek sonuçlara ne kadar yakınsadığı ve bu sonuçların ne kadar çeşitli olduğu kullanılan yöntemlerin performansı hakkında bilgi vermektedir. Baskın olmayan sıralama, ağırlıklı toplam, normal sınır kesişimi gibi metotlar çok-amaçlı optimizasyon problemlerinde sıklıkla kullanılan yaklaşımlardır. Bu yaklaşımlardan bazıları çeşitlilik açısından ön plana çıkarken bazılarının ise en iyi sonuca daha iyi yakınsadığı gözlenmiştir. Bu çalışmanın temel amacı elde edilen çözümleri hem çeşitlilik hem de yakınsama açısından en iyi hale getirmektir.Bu amaç kapsamında baskın olmayan sıralama ve adaptif ızgara yaklaşımları bir arada kullanılarak yeni bir hibrit yaklaşım geliştirilmiştir. Daha iyi bir yakınsama için baskın olmayan sıralama, çeşitlilik için adaptif ızgara yaklaşımı bir arada kullanılmıştır. Geliştirilen bu hibrit yaklaşım test problemleri ve doğrusal olmayan denklem sistemlerinde test edilerek sonuçları literatürde iyi bilinen Baskın Olmayan Sıralamalı Genetik Algoritma (NSGA-II) ve Çok-Amaçlı Parçacık Sürü Optimizasyonu (MOPSO) algoritmaları ile karşılaştırılmıştır. Deneysel sonuçlar incelendiğinde çeşitlilik ve yakınsama performansı açısından geliştirilen hibrit yaklaşımın kabul edilebilir olduğu gözlenmiştir.
Evaluation of Spinosad and Different Bacillus thuringiensis (Bacillaceae) Strains against the Larvae of Hyphantria cunea (Lepidoptera: Erebidae)

Published: October 2020

In this study, Bacillus thrungiensis aizawai Bonnefoi & de Barjac, 1963 (Florbac), different isolates of Bacillus thuringiensis (Bt) kurstaki Berliner, 1915 (Biobit, Delfin, Rapax, Rebound) and spinosad (Spintor) were assessed for their efficacy against different instars of Hyphantria cunea (Drury, 1773) (Lepidoptera: Erebidae) under laboratory and field conditions in 2019 in Duzce Province, Turkey. Spinosad was the most effective bioinsecticide, followed by Bt aizawai and Bt kurstaki isolates against various instars of H. cunea. In the laboratory, at 96 hour post-treatment, spinosad caused 98% mortality in 2nd and 3rd instars, and 83% mortality in 4th and 5th instars; Bt aizawai caused 98% mortality in 2nd and 3rd instars and 43% mortality in 4th and 5th instars; and Bt kurstaki isolates caused 95% mortality in 2nd and 3rd instars and 51% mortality in 4th and 5th instars. The results from the field study showed similar trends. The older instars were less susceptible to all the tested bioinsecticides than the younger instars, which may be attributable to the phenomenon known as “maturation immunity”. Bacillus thuringiensis kurstaki has already been recommended for management of this pest. Whereas the data indicated that spinosad and Bt aizawai could also be used as bioinsecticides for control H. cunea larvae.

Frontal fibrosing alopecia and lichen planus pigmentosus: a case series
Authors: Méndez Diana Marcela , Arenas Claudia Marcela , Morales Camilo Andrés
Published: October 2020

Frontal fibrosing alopecia is a type of scarring alopecia that has been associated with different skin lesions including lichen planus pigmentosus. Both diseases share common pathophysiological mechanisms, which explain their coexistence in the same patient. We report 12 cases of mestizo women with frontal fibrosing alopecia and lichen planus pigmentosus confirmed by histopathology and discuss the pathophysiological mechanisms shared by both diseases. The most important pathophysiological mechanism common to both diseases is the cytotoxic T-lymphocyte response, which is directed against keratinocytes and hair follicle stem cells, causing apoptosis and damage to the basal layer, with consequent tissue remodeling that deter­mines the clinical appearance of the lesions of frontal fibrosing alopecia and lichen planus pigmentosus.

Published: October 2020

El artículo analiza el contexto histórico de las pandemias, para dimensionar al COVID-19. A partir de allí, describe su evolución hasta la mitad de 2020; se argumenta que su impacto, generó una doble crisis: una sanitaria y otra económica, al presentarse cuasi al unísono, forzaron a los países a reaccionar en doble vía, con acciones de política de salud y conómica. Se plantea que las acciones de la política de salud, pusieron en jaque a las economías nacional e internacional y que los efectos de corto plazo, han hecho caer a la economía global en una profunda recesión. El artículo, enfatiza el análisis de la política de salud y económica que implementó China, siguiendo la ortodoxia, para contrarrestar su impacto económico y da cuenta puntual de su estrategia, cuya expectativa es recuperar su capacidad de recimiento y ser de las pocas economías que no caiga en crisis en 2020.
Animal Spirits y no-ergodicidad para COVID 19 en algunos estados de México
Authors: Aguilar Gutiérrez Genaro , Lagunas Puls Sergio
Published: October 2020

A partir de datos día a día de los fallecimientos por COVID-19 en México, se desarrolla un modelo de ajuste para la predicción de la cima de fallecimientos en cuatro estados de México; 2 con vocación turística y 2 con vocación industrial. Se pronostica que la cima o “pico” de fallecimientos ocurrirá el día 107 de la pandemia para el estado de Quintana Roo y los días 68, 109 y 72 para los estados de Baja California Sur, Estado de México y Nuevo León. Sin embargo, los hallazgos sugieren que el comportamiento no-ergódico es característico a fenómenos que dependen del comportamiento humano, debido al “animal spirits” que conduce a la irracionalidad en la toma de decisiones de las personas. La evidencia apunta a la necesidad de construcción de hipótesis alternativas, para analizar el comportamiento humano, ante fenómenos de incertidumbre.
