Kausalitas Anak dan Orang Tua : Relevansi antara Teori Konvergensi dalam Psikologi Pendidikan Barat dengan Teori Fitrah dalam Perspektif Islam
Authors: Sukarman .
Published: February 2020

Abstrak: Artikel ini merupakan kajian penelitian konseptual yang akan memaparkan pola hubungan kausalitas anak dan orang tua menurut teori konvergensi dalam psikologi pendidikan barat  dan  pandangan teori fitrah dalam perspektif  pendidikan Islam. Jika kedua teori ini disandingkan maka akan  ditemukan relevansi satu sama lain. Hal yang menarik dalam kajian ini adalah kedua teori ini menempatkan seorang anak sebagai pihak penerima pengaruh (pendidikan) sedangkan orang tua diposisikan sebagai pihak pemberi pengaruh (pendidikan) dalam kehidupan anak. Dalam pandangan Islam ketika orang tua telah tiada maka hasil pemberian pengaruh (pendidikan) terhadap anak akan berpengaruh pada kehidupan orang tuanya kelak. Sehingga dalam hal ini akan terdapat hubungan kausalitas antara keduanya. Kajian ini dilatarbelakangi adanya persoalan ketidaksepemahaman tentang tanggung jawab pendidikan antara guru dan orang tua. Metode penelitian menggunakan literature review dalam kajian deskriptif kualitatif. Penelitian ini mencoba membandingkan antara dua teori pendidikan barat dan teori pendidikan Islam. Simpulan dari kajian tentang teori konvergensi dan teori fitrah adalah adanya satu titik temu antara keduanya meskipun kedua teori tersebut bersumber dari sumber yang berbeda yakni literatur barat dan literatur Islam. Kata kunci: kausalitas, konvergensi, Islam.

Visual acuity and color discrimination in patients with cataracts
Authors: Langina-Jansone Z. , Truksa R. , Ozolinsh M.
Published: February 2020

Color vision tests can give information about pathological changes in eye structures. The purpose of our research was to study the color vision sensitivity and visual acuity changes before and after cataract surgery. We used a saturated Farnsworth D15 color vision arrangement test to check color sensitivity changes in confusion line directions. The test is easily perceptible (essential to eldery patients), and it is possible to check color sensitivity changes in tritan, protan, and deutan confusion line directions. The results were analyzed in several ways: by summing the color differences between adjacent caps according to Bowman and averaging the color difference vectors according to Vingrys and King–Smith. Color difference vectors determine the severity (or confusion), selectivity (or scatter), and type of color deficiency to the presented cap arrangements. In the least squares regression method, the error type is determined by the angular proximity of the best-fit line to known confusion axes representing protan, deutan, tritan, or unspecified color defects. All three tests showed that cataract-induced lens opacity significantly decreases a patient’s chromatic resolution in the visible light region. Before the cataract surgery, the D15 test stimulus arrangement sequence showed similarities with tritan color deficiency.
Theoretical analysis of compact cylindrical microlenses for terahertz photoconductive antennas in the photomixer regime
Authors: Søndergaard Thomas , Sauer Mikkel O. , Nielsen Carl E. M. , Merring-Mikkelsen Lars , Sørensen Christian B. , Skovsen Esben
Published: February 2020

A terahertz photoconductive antenna placed on the back side of a semiconductor slab with and without a compact cylindrical semiconductor microlens on the front side is studied theoretically. The antenna is operated as a photomixer giving narrowband radiation at 1 THz. Radiation patterns and emitted powers are found to oscillate with slab thickness as a consequence of multiple-reflection interference. It is further shown that an antireflection layer on the lens may eliminate these oscillations to a large extent. In the absence of a lens, most of the radiation is trapped inside the semiconductor slab, and the radiation pattern is far from that of a pencil-beam. Both light trapping and radiation patterns are shown to be significantly improved by a very compact lens with a size smaller than a cubic wavelength. The improvements on outcoupling of radiation in a predominantly forward direction versus lens radius and height are mapped out. The calculated outcoupling efficiency of the antenna-lens system takes into account the Purcell effect and radiation trapped in the semiconductor slab. The antenna-lens system is modeled rigorously by using the Green’s function volume integral equation method in a form that exploits cylindrical symmetry.

Intensity-dependent effective four-photon absorption (4PA) coefficients in GaP and ZnTe semiconductors were measured by the z-scan method using pump pulses of 1.75 µm wavelength, 135 fs duration, and up to 500 GWcm−2 intensity. A nonlinear pulse propagation model, including linear dispersion and 4PA was used to obtain the 4PA coefficients from measurements. The intensity-dependent effective 4PA coefficients vary from 2.6 × 10−4 to 65 × 10−4 cm5GW−3 in GaP, and from 3.5 × 10−4 to 9.1 × 10−4 cm5GW−3 in ZnTe. The anisotropy in 4PA was shown in GaP. The knowledge of 4PA coefficients is important for the design of semiconductor photonics devices.
Visual cryptography in single-pixel imaging
Authors: Jiao Shuming , Feng Jun , Gao Yang , Lei Ting , Yuan Xiaocong
Published: February 2020

Two novel visual cryptography (VC) schemes are proposed by combining VC with single-pixel imaging (SPI) for the first time. It is pointed out that the overlapping of visual key images in VC is similar to the superposition of pixel intensities by a single-pixel detector in SPI. In the first scheme, QR-code VC is designed by using opaque sheets instead of transparent sheets. The secret image can be recovered when identical illumination patterns are projected onto multiple visual key images and a single detector is used to record the total light intensities. In the second scheme, the secret image is shared by multiple illumination pattern sequences and it can be recovered when the visual key patterns are projected onto identical items. The application of VC can be extended to more diversified scenarios by our proposed schemes.
Hand-guided qualitative deflectometry with a mobile device

Published: February 2020

We introduce a system that exploits the screen and front-facing camera of a mobile device to perform three-dimensional deflectometry-based surface measurements. In contrast to current mobile deflectometry systems, our method can capture surfaces with large normal variation and wide field of view (FoV). We achieve this by applying automated multi-view panoramic stitching algorithms to produce a large FoV normal map from a hand-guided capture process without the need for external tracking systems, like robot arms or fiducials. The presented work enables 3D surface measurements of specular objects ’in the wild’ with a system accessible to users with little to no technical imaging experience. We demonstrate high-quality 3D surface measurements without the need for a calibration procedure. We provide experimental results with our prototype Deflectometry system and discuss applications for computer vision tasks such as object detection and recognition.

Published: February 2020

We present the design of an adiabatic taper coupled Ge1−xSi
x
electro-absorption modulator, which is based on Franz-Keldysh effect. The device has an active region of 0.8×50 µm2, an extinction ratio of more than 6 dB and an insertion loss less than 3 dB at the wavelength of 1550 nm. The operating bandwidth can be broadened to more than 90 nm by an AlN block assisted heater with only 6.2 mW energy consumption. Moreover, the operating wavelength shift caused by material composition deviation can be compensated to the expected wavelength by thermal tuning. This design may play an important role in next-generation, high-density optical integrations for datacom and high-performance computing.
Omni-resonant space–time wave packets

Published: February 2020

We describe theoretically and verify experimentally a novel, to the best of our knowledge, class of diffraction-free pulsed optical beams that are “omni-resonant”: they have the remarkable property of transmission through planar Fabry–Perot resonators without spectral filtering, even if their bandwidth far exceeds the cavity linewidth. Ultrashort wave packets endowed with a specific spatiotemporal structure couple to a single resonant mode independent of its linewidth. We confirm that such “space–time” omni-resonant wave packets retain their bandwidth (1.6 nm), spatiotemporal profile (1.3-ps pulse width, 4-µm beam width), and diffraction-free behavior upon transmission through cavities with resonant linewidths of 0.3 nm and 0.15 nm.
Partial quantum revivals of localized condensates in distorted lattices
Authors: Ko Dogyun , Sun Meng , Andreanov Alexei , Rubo Y. G. , Savenko I. G.
Published: February 2020

We report on a peculiar propagation of bosons loaded by a short Laguerre–Gaussian pulse in a nearly flat band of a lattice potential. Taking a system of exciton polaritons in a kagome lattice as an example, we show that an initially localized condensate propagates in a specific direction in space, if anisotropy is taken into account. This propagation consists of quantum jumps, collapses, and revivals of the whole compact states, and it persists given any direction of anisotropy. This property reveals its signatures in the tight-binding model, and, surprisingly, it is much more pronounced in a continuous model. Quantum revivals are robust to the repulsive interaction and finite lifetime of the particles. Since no magnetic field or spin–orbit interaction is required, this system provides a new kind of easily implementable optical logic.
Experimental observation of differential self-mixing interference signals using a randomly polarized laser: a differential self-mixing interferometry
Authors: Qi Pan , Cheng Jiajian , Li Shiping , Zhang Zibang , Song Guanping , Weng Jiawen , Zhong Jingang
Published: February 2020

Differential measurement has strong anti-interference ability. We report the first, to the best of our knowledge, experimental demonstration of differential self-mixing interference signals using a randomly polarized laser for differential self-mixing interferometry (SMI). In the differential SMI system, the detection light can be divided into interference signals of

p

-polarized and

s

-polarized light with identical intensity and pi-shift phase difference. By exploiting such a new experimental phenomenon, we propose a noise-robust and low-cost self-mixing interferometer. Experiments show that the proposed approach can effectively suppress both periodic and aperiodic noise. Thus, the reported phenomenon and approach has a good application prospect in self-mixing interferometers.

Published: February 2020

We propose and demonstrate a method to generate a flat broadband chaotic laser by using an active optical feedback loop combined with a high nonlinear fiber. The feedback strength and nonlinear effect, especially the four-wave mixing effect of high nonlinear fiber, are studied to improve the bandwidth and flatness of chaos. When the feedback strength is 6.6 and injected fiber power is 1.0 W, a chaotic signal with a frequency range over 50 GHz, 80% bandwidth of 38.9 GHz, and flatness of 4.2 dB are experimentally achieved.

Published: February 2020

In this Letter, we report a novel integrated additive and subtractive manufacturing (IASM) method to fabricate an information integrated glass module. After a certain number of glass layers are 3D printed and sintered by directCO2laser irradiation, a microchannel will be fabricated on top of the printed glass by integrated picosecond laser, for intrinsic Fabry–Perot interferometer (IFPI) optical fiber sensor embedment. Then, the glass 3D printing process continues for the realization of bonding between optical fiber and printed glass. Temperature sensing up to 1000°C was demonstrated using the fabricated information integrated module. In addition, the long-term stability of the glass module at 1000°C was conducted. Enhanced sensor structure robustness and harsh temperature sensing capability make this glass module attractive for harsh environment structural health monitoring.

Authors: Tydykova N.V.
Published: February 2020

The article is devoted to a comparative legal study of the norms providing for criminal liability for sexualcrimes in the Russian Federation and some European countries. Some features of criminal liability for thisgroup of crimes in Spain, France, Israel, Norway, Sweden, Switzerland are investigated. It is noted that theapproach to differentiation for violent sexual crimes in different countries is different. Several qualifyingcircumstances were noted that could be borrowed to improve our legislation. These include: the commissionof the alleged assault, by a relative, relative or relative by virtue of adoption, or by any other person havingauthority over the victim; if the victim has come into contact with the perpetrator of criminal acts throughthe use of telecommunication networks; if the act is committed by several persons acting as performersor accomplices; using his official position. The rule that if two or more of the qualifying circumstances arepresent is assessed, the penalty is imposed closer to the upper limit of the sanction. It is proposed to carry out an additional analysis of the ban on disclosing the person’s name or any other data that may indicatethe person as a victim or as having lodged a complaint that he is a victim of a crime against sexual freedomor sexual integrity. Attention is also drawn to sanctions for the group of crimes under consideration. In theRussian criminal law they are more humane than in foreign countrie
LEGAL SYMBOL AND LEGAL FICTION: PROBLEMS OF DEMARCATION
Authors: Zatsepina O.E.
Published: February 2020

The article considers the legal symbol and legal fiction as special legal categories. The correctness of anarrow approach to their essence was established according to which the notion of «legal fiction» does notinclude fictitious phenomena, and the notion of «legal symbol» does not cover symbols prohibited by law,and symbols which represent certain values. It was revealed that both considered categories have a certaindegree of conventionality, in a specific way according to the scheme established by the legislator, thereforethey are sometimes mixed in the literature. Legal symbols, unlike legal fictions, are more fundamental, buthave an auxiliary character, since they reflect an existing legal precept, and are not part of a new legal norm,contain an encrypted meaning, but do not distort the legal reality.Legal symbols and legal fictions play a very important role in legal regulation, since they optimize it andmake it more quality, and also provide legal and linguistic economy.

Painter Alfred Krupa (1915-1989) was the very first man who invented the suitcase with wheels in the early 1950's
Authors: Krupa Alfred Freddy
Published: February 2020

According to the UNTWO (World Tourism Organization) 1.2 billion people made an international trip in 2015 , and it is predicted that it will rise to 1.8 billion world travelers in 2025. Suitcase with wheels is known to all those who traveled but the real inventor of it is not known to everyone.Many journalists reported that in 1970,
Bernard Sadow, then the owner of the American company U.S. Luggage (now part of the Briggs & Riley TRAVELWARE) invented and patented in 1972 first suitcase with wheels and so changed the world of travel.It is true is that Bernard Sadow was the one who patented with success suitcase with wheels but not the first man who invented it and use it in daily travelling. Those are, of course, two separate things.The fact of the history is that the painter
Alfred Krupa was the very first man who invented the suitcase with wheels sometime before or in 1954 (in period 1950-1954). And that is only one among his popular creations from early 1950's.
Causas de não recebimento do leite cru refrigerado em usina de beneficiamento do Agreste Meridional de Pernambuco
Authors: Leite Ana Erundina De Luna Moraes , Mendonça Marcelo , Mendonça Karla Sequeira , Franque Marcos Pinheiro
Published: February 2020

O leite possui constituintes de grande valor nutricional e sua produção e consumo têm crescido a cada ano mundialmente. Associado à sua importância econômica, este produto é constantemente alvo de fraudes e adulterações, as quais trazem como consequência grandes prejuízos à indústria e preocupação aos órgãos de saúde pública. Neste sentido, objetivamos analisar, de forma retrospectiva, as causas que determinaram o não recebimento do leite cru refrigerado em usina de beneficiamento sob Inspeção Federal, da região do Agreste Meridional de Pernambuco, durante o período que compreendem os meses de março a outubro de 2016, com base no arquivo de registros da empresa. Foram identificados 122 casos de não recebimento de leite cru refrigerado. Destes, a principal causa foi a adição de água (34,5%), seguida por acidez acima do limite estabelecido pela empresa, máximo 0,16 g de ácido lático/100 mL de leite (30,3%), e presença de resíduos de antibióticos no leite (26,2%). Desta forma, reforçou-se a importância do controle de qualidade e de identidade do leite realizado pela empresa, para evitar que um leite adulterado seja processado pela indústria e disponibilizado ao consumidor. Reforçou-se, também, a necessidade de aprimoramento da política leiteira, para fins de esclarecer, orientar e incentivar os produtores com relação a implementação das Boas Práticas Agropecuárias de produção do leite, incluindo a necessidade da realização de uma Ordenha Higiênica, do respeito do tempo de carência dos antibióticos utilizados no tratamento dos animais e, principalmente, os prejuízos causados pela adição de substâncias fraudulentas.
Memórias em Palimpsesto: prédios e espaços escolares nas narrativas de estudantes em Porto Alegre/RS (1920-1980)
Authors: Grimaldi Lucas Costa , Almeida Dóris Bittencourt
Published: February 2020

O presente estudo investiga narrativas de memórias orais de estudantes acerca de espaços e prédios escolares por eles habitados, no período de 1920 a 1980. Tem-se como principal objetivo a produção de uma espécie de cartografia das sensações sobre os espaços vividos durante a escolarização, identificadas na documentação. A pesquisa privilegiou o exame do conteúdo discursivo das oito entrevistas realizadas, tendo como metodologia a História Oral. A partir das análises das recorrências e dissonâncias nas narrativas, construíram-se duas categorias de análise: “O Antigo e o Novo: relações entre os estudantes e os prédios das escolas”; “Entre a vigilância e a diversão: o espaço escolar como elemento curricular”; Para a pesquisa, os espaços da escolarização adquirem um lugar de destaque na hora de rememorar. E estas lembranças, carregadas de ressignificação, trazem evidências para compreender a arquitetura escolar como agente na construção de sensibilidades estudantis.
Alfabetização de jovens e adultos no Brasil: uma face da História nas produções acadêmicas no final do Século XX
Authors: Rocha Juliano Guerra , Goulart Ilsa do Carmo Vieira
Published: February 2020

Tomando as produções acadêmicas como fonte histórica, esse estudo tem por objetivo analisar e compreender a história da alfabetização de jovens e adultos no Brasil a partir dos discursos acadêmicos produzidos no período de 1978 a 2000. A demarcação temporal inicial, 1978, se justifica por ter ocorrido nesse ano a defesa da primeira pesquisa de Dissertação de Mestrado identificada sobre alfabetização de adultos vinculada a um programa de pós-graduação brasileiro, e a final, o ano de 2000, para situarmos este artigo no âmbito do século XX. Desse modo, apresentamos um panorama de como as pesquisas brasileiras abordaram o tema alfabetização de jovens e adultos antes e depois da promulgação da Lei de Diretrizes e Bases da Educação Nacional n.º 9394, de 1996, momento em que, no Brasil, a Educação de Jovens e Adultos foi reconhecida como modalidade de ensino.
A história da alfabetização de adultos no ensino, na pesquisa e na extensão da UFU e da UFMG (1986-2019)
Authors: Maciel Francisca Izabel Pereira , Santos Sônia Maria dos
Published: February 2020

Em um país, historicamente marcado pelos altos índices de analfabetismo – atualmente com 11,3 milhões de analfabetos– é possível constatar, por meio das pesquisas teóricas, como também nos profissionais da área da educação, que a EJA possui um lugar periférico nas políticas públicas, nas atividades, nas produções acadêmicas, principalmente no que diz respeito à alfabetização de jovens e adultos. Neste artigo, propomos uma reflexão sobre a história de alfabetização de adultos, a partir de Projetos desenvolvidos no campo do ensino, da pesquisa, e da extensão desenvolvidos em duas instituições federais, a Universidade Federal de Uberlândia (UFU) e a Universidade Federal de Minas Gerais (UFMG), desde a década de 80. O tripé das Universidades públicas são as atividades de ensino, pesquisa e extensão. Portanto, tematizar e refletir sobre a importância de projetos de extensão nas Universidades é o objetivo deste artigo. Nem sempre as atividades extensionistas são valorizadas nos meios acadêmicos e o mesmo ocorre quando se trata da educação de jovens e adultos. Neste artigo, duas pesquisadoras buscam narrar suas histórias de projetos de pesquisa e extensão vivenciadas no campo acadêmico da alfabetização de adultos. No caso da UFMG, foi criado um projeto de pesquisa, inicialmente, coordenado por professores da Faculdade de Letras, cujo objetivo era compreender o processo de aquisição da leitura e da escrita em adultos analfabetos. A partir de 1986, o projeto foi integrado à Faculdade de Educação, ampliado ao longo dos anos como um projeto de extensão, ensino e pesquisa de pós-graduandos da linha Educação e Linguagem do Programa de Pós-Graduação da FaE/UFMG. Refletir sobre a longa duração desse Projeto ajuda-nos a entender o lugar das universidades no processo educativo e no compromisso social que a academia deve ter com as camadas menos favorecidas e na socialização da produção dos conhecimentos acadêmicos. Quanto a UFU, o processo foi inverso ao da UFMG, pois nesta universidade, a EJA aparece inicialmente e de forma tímida na extensão com cursos isolados e uma sala de alfabetização de EJA onde há mais de 15 anos atende alunos com problemas psicossociais. Essa experiência foi se consolidando não só na extensão como também um dos campos de pesquisa sobre a história da alfabetização na EJA nas linhas do PPGED/FACED/UFU, e ainda nos cursos de aperfeiçoamento financiados pela SEB/MEC e SECADI/MEC, a partir de 2009.
Mourning, Affect, Sociality: On the Possibilities of Open Grief
Authors: Wool Zoë
Published: February 2020

This essay examines mourning and the possibilities for open grief among veterans, asking how the traces of what has been lost persist into the present in ways that find no easy resolution. It questions the normative value of an end to mourning, proposing instead that grief—and indeed our anthropological formulations of the meaning of such affects and events—might be held open, trace and memory maintained, imagining recognition as something open-ended that might recast discomfort as the potential for a different kind of sociality.

Published: February 2020

Plasma-assisted catalytic cracking is an attractive method for producing biofuels from vegetable oil. This paper studied the effect of reactor temperature on the performance of plasma-assisted catalytic cracking of palm oil into biofuels. The cracking process was conducted in a Dielectric Barrier Discharge (DBD)-type plasma reactor with the presence of spent RFCC catalyst. The reactor temperature was varied at 400, 450, and 500 ºC. The liquid fuel product was analyzed using a gas chromatography-mass spectrometry (GC-MS) to determine the compositions. Result showed that the presenceof plasma and catalytic role can enhance the reactor performance so that the selectivity of the short-chain hydrocarbon produced increases. The selectivity of gasoline, kerosene, and diesel range fuels over the plasma-catalytic reactor were 16.43%, 52.74% and 21.25%, respectively, while the selectivity of gasoline, kerosene and diesel range fuels over a conventional fixed bed reactor was 12.07%, 39.07%, and 45.11%, respectively. The increasing reactor temperature led to enhanced catalytic role of cracking reaction,particularly directing the reaction to the shorter hydrocarbon range. The reactor temperature dependence on the liquid product components distribution over the plasma-catalytic reactor was also studied. The aromatic and oxygenated compounds increased with the reactor temperature.©2020. CBIORE-IJRED. All rights reserved

Published: February 2020

In this study, hybrid solar drying of coffee beans was performed, and energy analysis was carried out, to assess the system’s performance, in terms of energy efficiency, compared to solar drying and the open sun drying method. The dryer has three compartments: solar collector for collecting solar radiation, drying chamber, and a Liquid Petroleum Gas burner, which acted as an auxiliary heater to assist the thermal energy. The drying chamber has four trays for placing the dried product. The initial moisture content of coffee beans was 54.23% w.b and was reduced to the final moisture content between 11-12% w.b. The coffee beans dried faster when subjected to the solar hybrid drying method, compared to other methods, with the dryer temperature of 40°C, 50°C, and 60°C. Results indicated that the coffee beans’ drying times varied from 10 to 14 hours. However, at temperature 50°C and 60°C for the 1st tray, the water content was reduced more rapidly compared to the other tray. From the results of this study, we can see the different efficiency of solar collector that shows of 54.15% at variable temperature 60°C for drying time 12:00 to 14:00 p.m for hybrid solar drying and for the solar drying process is 50.07% at the range of drying time 12:00 to 14:00 p.m. Mathematical modelling shows that Page model is the most suitable for describing the coffee beans’ drying behaviour using a hybrid solar dryer.

Authors: Hadi Eko Sasmito , Iqbal Muhammad , Wibawa Ari , Kurdi Ojo , Karnoto Karnoto
Published: February 2020

This paper discusses an experimental study of a wave energy converter (WEC) without using reaction from the seabed. The WEC uses buoys and heave plates, which can react to their self-reacting. The interaction force between heave plates and buoys can absorb energy from ocean waves better. The heave plate model affects the output of energy produced. It is presented in this study with variations in the position of upright plates. The research aims to measure the influence of the place of the addition of vertical plates into heave plates on the WEC on the hydrodynamic performance (coefficient of mass increase, drag coefficient, and KC value) and the interaction of the force it produces with the buoy on regular waves. The conclusion is the vertical plate position makes the coefficient of mass added Ca increase with an increasing amount of KC, and an almost linear relationship was observed between them. As the frequency increases, the value of C increases slightly, but it is not clear. Thus, the oscillating frequency has little effect on the mass coefficient of added heave plates with vertical plates. Thus, the change in the vertical plate position has only a powerful effect on KC < 0.75. ©2020. CBIORE-IJRED. All rights reserved

Authors: DMITRIEVA Oksana , IVANOV Semen
Published: February 2020

Field experiments were carried out in the Chuvash Republic, which is located in the center of the European part of Russia on the banks of the Volga River and has a moderately continental climate with warm summers, cold winters, well-defined transitional seasons and average annual rainfall of 500 mm. There are many cultural and wild species of amaranth in nature, differing in morphological and biological features. The objects of research were four common species of amaranth (Amaranthus spp.): A. cruentus L., A. caudatus L., A. hybridus L., A. spinosus L.. Particular attention in the experiment was paid to the morphological and biological characteristics of plants according to the growth stages during growing season and the formation of the yield of green mass and grain during 3 years of research. As a result of the experiment, the possibility of cultivating a heat-loving amaranth culture in the climatic conditions of the Chuvash Republic was proved and adaptive species for growing green mass (A.cruentus and A.caudatus) and for grain (A.cruentus) were identified.
Multiprojective witness sets and a trace test
Authors: Hauenstein Jonathan D. , Rodriguez Jose Israel
Published: February 2020

In the field of numerical algebraic geometry, positive-dimensional solution sets of systems of polynomial equations are described by witness sets. In this paper, we define multiprojective witness sets which encode the multidegree information of an irreducible multiprojective variety. Our main results generalise the regeneration solving procedure, a trace test, and numerical irreducible decomposition to the multiprojective case. Examples are included to demonstrate this new approach.

Group theory, the ultimate theory for symmetry, is a powerful tool that has a direct impact on research in robotics, computer vision, computer graphics and medical image analysis. Symmetry is very important in chemistry research and group theory is the tool that is used to determine symmetry. Usually, it is not only the symmetry of molecule but also the symmetries of some local atoms, molecular orbitals, rotations and vibrations of bonds, etc. that are important. Harada-Norton group is an example of a sporadic simple group. There are 14 maximal subgroups of Harada-Norton group. Generators (also known as words) of 11 maximal subgroups are already known. The aim of this note is to give generators of the remaining 3 maximal subgroups, which is an open problem mentioned on A World-wide-web Atlas of Group Representations (http://brauer.maths.qmul.ac.uk/Atlas) [1]. In this report we compute the generators of A6 × A6.D8, 23+2+6.(3 × L3(2)) and 34 : 2.(A4 × A4).4. Moreover we also compute the generators for the Maximal subgroups of some linear groups.

We consider an adaptive finite element method with arbitrary but fixed polynomial degree

, where adaptivity is driven by an edge-based residual error estimator.
Based on the modified maximum criterion from
[L. Diening, C. Kreuzer and R. Stevenson,
Instance optimality of the adaptive maximum strategy,
Found. Comput. Math. 16 2016, 1, 33–68],
we propose a goal-oriented adaptive algorithm and prove that it is instance optimal.
More precisely, the goal error is bounded by the product of the total errors (being the sum of energy error plus data oscillations) of the primal and the dual problem, and the proposed algorithm is instance optimal with respect to this upper bound.
Numerical experiments underline our theoretical findings.
Atom-specific persistent homology and its application to protein flexibility analysis
Authors: Bramer David , Wei Guo-Wei
Published: February 2020

Recently, persistent homology has had tremendous success in biomolecular data analysis. It works by examining the topological relationship or connectivity of a group of atoms in a molecule at a variety of scales, then rendering a family of topological representations of the molecule. However, persistent homology is rarely employed for the analysis of atomic properties, such as biomolecular flexibility analysis or B-factor prediction. This work introduces atom-specific persistent homology to provide a local atomic level representation of a molecule via a global topological tool. This is achieved through the construction of a pair of conjugated sets of atoms and corresponding conjugated simplicial complexes, as well as conjugated topological spaces. The difference between the topological invariants of the pair of conjugated sets is measured by Bottleneck and Wasserstein metrics and leads to an atom-specific topological representation of individual atomic properties in a molecule. Atom-specific topological features are integrated with various machine learning algorithms, including gradient boosting trees and convolutional neural network for protein thermal fluctuation analysis and B-factor prediction. Extensive numerical results indicate the proposed method provides a powerful topological tool for analyzing and predicting localized information in complex macromolecules.
Anger stinks in Seri: Olfactory metaphor in a lesser-described language
Authors: O’Meara Carolyn , Majid Asifa
Published: February 2020

Previous studies claim there are few olfactory metaphors cross-linguistically, especially compared to metaphors originating in the visual and auditory domains. We show olfaction can be a source for metaphor and metonymy in a lesser-described language that has rich lexical resources for talking about odors. In Seri, an isolate language of Mexico spoken by indigenous hunter-gatherers, we find a novel metaphor for emotion never previously described – “anger stinks”. In addition, distinct odor verbs are used metaphorically to distinguish volitional vs. non-volitional states-of-affairs. Finally, there is ample olfactory metonymy in Seri, especially prevalent in names for plants, but also found in names for insects and artifacts. This calls for a re-examination of better-known languages for the overlooked role olfaction may play in metaphor and metonymy. The Seri language illustrates how valuable data from understudied languages can be in highlighting novel ways by which people conceptualize themselves and their world.

Empirical Evaluation of High-speed Cost-effective Ro-FSO System by Incorporating OCDMA-PDM Scheme under the Presence of Fog
Authors: Chaudhary Sushank , Choudhary Sunita , Tang Xuan , Wei Xian
Published: February 2020

Radio over free space optics (Ro-FSO) innovation saddles the vast limit of optical fiber and the portability from local to remote systems. To enhance the capacity of Ro-FSO systems without compromising the bandwidth, this work incorporates use of hybrid polarization division multiplexing (PDM) with optical code division multiplexing (OCDMA) schemes. Due to low deployment time and support cost, the vast majority of the current optical network application systems adopts free space optics (FSO) as the elective answer for suitably supplanting fiber optical cable. This study has incorporated PDM and OCDMA schemes to design a 50 Gbps Ro-FSO link. Ten channels, each with 5 Gbps of data, are transported via FSO link of 3500 m. In addition, the proposed PDM-OCDMA-Ro-FSO link is evaluated under various atmospheric commotions.

Background

The intima-media thickness of the carotid artery (cIMT) and endothelial dysfunction are associated with cardiovascular (CV) disease.

Objectives

To evaluate the correlation between cIMT, brachial intraluminal diameter and flow-mediated vasodilation on the reactive hyperemia phase in adolescents with obesity with predictors of CV risk.

Methods

Seventy-three pubertal patients with overweight or obesity were evaluated (45 girls) with a mean (standard deviation [SD]) age of 12.9 (2.5) years. Patients underwent anthropometric measurements and had the lipid profile, oral glucose tolerance test (oGTT) and serum intercellular adhesion molecule-1 (sICAM-1) levels analyzed. The ratios of the waist circumference (WC)/height (WHtR) and triglycerides (TG)/high-density lipoprotein cholesterol (HDL-C), homeostatic model assessment of insulin resistance (HOMA-IR), the Matsuda index and insulin area under the curve (AUC) were calculated. All patients were evaluated for cIMT and arterial blood flow velocity of the brachial artery.

Results

75.3% of the patients had high cIMT values. We found a positive correlation between WHtR and cIMT (r = 0.233; p = 0.050). There was a positive correlation between sICAM-1 and insulin AUC (r = 0.323; p = 0.012) and WHtR (r = 0.258; p = 0.047). Patients with abnormal arterial dilation had higher sICAM-1 values (p = 0.02) despite having smaller WHtR (p = 0.046).

Conclusions

These adolescents with obesity had high cIMT values. Insulin resistance was associated with sICAM-1. Endothelial dysfunction was positively correlated with sICAM-1. There is no consensus about what the best laboratorial approach to evaluate insulin resistance in adolescents is, and the cutoff values of each method are arbitrary. So, as we saw earlier, the association between anthropometric data (WHtR) and ultrasound findings could be useful to evaluate the CV risk of these adolescents with obesity, because of its practical, direct and low-cost value.
The association between vitamin D levels and precocious puberty: a meta-analysis
Authors: Liu Shanshan , Zhu Xun , Wang Yuanxin , Yan Shoumeng , Li Dong , Cui Weiwei
Published: February 2020

The objective of this short communication was the relationship between vitamin D and precocious puberty (PP). In this study, a comprehensive search of multiple databases was performed to identify studies focused on the association between vitamin D deficiency and PP. Studies that compared serum vitamin D levels between patients with PP and controls were selected for the systematic meta-analysis. The main outcome was the mean difference in serum vitamin D levels between PP and controls. Vitamin D-deficient subjects were more likely to develop PP. Our findings suggest that PP may be linked to vitamin D deficiency. Thus, providing supplements of vitamin D to PP patients may improve their nutritional status and prevent diseases. But, the amount of vitamin D required is uncertain, so it is important to be careful when taking vitamin D supplements.
