Дифференцирование функций кватернионной переменной
Authors: Полякова Надия Салихжановна
Published: January 2020

В данной работе рассматривается определение дифференцируемости и регулярностипо Фютеру [1–2] и примеры регулярных по Фютеру функций, приводится и определениеС-регулярности и С-производной или производной Куллена [3], на основе которой строитсяновая теория регулярных функций в [4], которая уже включает полиномы и сходящиеся ря-ды гиперкомплексной переменной как дифференцируемые функции. Затем предлагаетсяновое определение дифференцируемости, имеющее классический вид, но со специфиче-ской сходимостью, которое позволяет доказать теоремы о дифференцируемости суммы ипроизведения дифференцируемых функций, о дифференцируемости “частного” дифферен-цируемых функций. Далее выводится производная степени и доказывается дифференци-руемость полиномов и степенных рядов, что позволяет строить обобщения элементарныхфункций для кватернионных аргументов. Приводится пример, показывающий, что без спе-цифической сходимости приведенное определение дифференцируемости теряет смысл. Спомощью степенных рядов задаются функции, которые являются решениями дифферен-циальных уравнений с постоянными кватернионными коэффициентами. Рассматриваетсязадача отыскания корней квадратного уравнения с кватернионными коэффициентами, ко-торая возникает при решении дифференциальных уравнений

A sociedade atual vivencia uma nova revolução ocasionada pelo avanço das Novas Tecnologias da Informação e Comunicação. Contudo, a prática docente não parece acompanhar as transformações das tecnologias (COLLINS & HALVERSON, 2018). Baseando-se na necessidade de mudança, este artigo tem como objetivo demonstrar como a tecnologia digital disponível para análise de corpora pode contribuir para o aprimoramento da prática do professor de línguas. Inicialmente, apresenta-se uma breve revisão sobre a linguística de corpus e a ferramenta de análise Sketch Engine. Após, explica-se um exemplo de proposta didática planejada para o ensino-aprendizagem de verbos utilizados na situação comunicativa de ida ao médico em espanhol. Em seguida, descreve-se a metodologia de pesquisa da linguística de corpus e analisam-se os dados obtidos no Sketch Engine. Foram utilizados quatro corpora para análise, sendo um geral e um especializado para a língua espanhola e outros dois para a língua portuguesa. Através do recurso Word Sketch, pesquisaram-se as colocações mais frequentes com o verbo doler/doer e os nomes dolor/dor, enfermedad/doença e enfermo/doente. Discutem-se os problemas e soluções encontrados na pesquisa e conclui-se o artigo reafirmando a importante contribuição da linguística de corpus para o aprimoramento da prática docente.

Authors: Handayani L , Amelia R , Putera F H A
Published: January 2020

Climate models that are able to simulate rainfall in Indonesia so far have not been found. The highly complex topography and interaction of the sea, land and atmosphere adds to the complexity of simulations and predictions of rainfall in Indonesia, particularly in Central Sulawesi. This research focuses on utilizing the results of prediction or forecast rainfall. Rainfall forecasting results obtained are then modeled with data on the level of rice production, so we can predict the future supply of rice (rice). This study examines statistical downscaling modeling with a generalized additive model approach to describe the rainfall events that occur within a certain time period. The data used is rainfall data in Central Sulawesi Province, because this region is a supplier of rice in Sulawesi.

ABSTRACTBreast cancer is a condition where the cell has lost control and its normal mechanism, so that abnormal growthoccurs quickly and uncontrollably that occurs in breast tissue. The basic thing that needs to be known about thecancer is the stage, so that the handling of the patient can be done correctly. In determining the cancer stage Union for International Cancer Control (UICC) uses several indicators, namely, the primary tumor which describes the size of the tumor and the expansion of the tumor to the chest wall, involvement of lymph nodes around the breast and distant metastases to other organs. Therefore, it is necessary to have a decision support system application that aims to classify cancer patient data based on the Stadium. One classification method that looks for the Decision Rule is the Rough Set. Basically this Rough set method is a decision-making method that is used to find a pattern from the data set that is processed. So that a pattern / rule can be obtained that can be used as a reference in decision making. In this study the pattern obtained as many as 16 will be entered into the Net-Bean software with java language so that it becomes a decision support system, then the system will be tested using 135 test data From these tests, namely by comparing the actual data with the results obtained from the decision support system application. So, the accuracy is 100%.Keywords : Classification, Breast Cancer Stadium, Rough Set.

The aim of the article is to present the motivation behind foreign expansion of small and medium-sized enterprises (SMEs) based in Łódź Voivodeship. In order to carry out the project the researchers analysed the literature on the subject and conducted primary research on the sample of the selected companies with the use of survey and interview questionnaires that the managers of the companies surveyed responded to in 2017 and 2018.The decisions to enter foreign markets also resulted from the fact that companies wanted to increase their turnover and profits and in some cases, as the research proved, they were also motivated by factors concerning the companies productivity. Companies perceive foreign market expansion as an opportunity to expand their product offer, enter new markets, implement innovative solutions or achieve the previously set strategic goals, which is referred to as the so called strategic motivation.
STRATEGIES FOR THE DEVELOPMENT OF AVERAGE POLISH DAIRY FARMS IN THE CONDITIONS OF A SINGLE EUROPEAN MARKET
Authors: Parzonko Andrzej
Published: January 2020

The paper aims to achieve two objectives: 1) To determine the competitive potential of Polish dairy farms and assess the economic results they achieved compared to other European Union entities, 2) To determine and assess the economic effects of possible development directions (strategies) for average Polish dairy farms. The analyses show that the production and economic potential of dairy farms from the European Union countries, characterized by the largest increase in milk production in years 2005–2015, was very diverse. On average, in 2016, the total value of the fixed assets of a Danish agricultural holding was 16 times higher than the value of the fixed assets of a farm in Poland and the average net value added generated by a Polish farm in 2016 was over thirteen times lower compared to Danish farms. However, if we take into account the costs of engaging external factors of production (land, labour and capital), it turns out that Danish farms are losing their advantages. The simulations of three possible variants of development for an average Polish dairy farm showed that good economic results were generated by the variant in which the land was leased and farm holders got employment outside the farm. The variant, which assumed an increase in the number of dairy cows (from 15 to 30) and the resulting growth in milk production could potentially give a slightly higher total net income for the farm family in the first two years, but it was certainly more risky.

Recognition versus Disclosure of Future Loss Conditions and the Decision-Usefulness of Financial Statements
Authors: Kunz Alexis H. , Staehle Martin
Published: January 2020

We conduct an experiment to investigate the differential effect of recognizing versus disclosing reasonable and supportable forecasts of future loss conditions on investors' valuation assessments when economic fundamentals either deteriorate or improve. Our main finding is that when entities enjoy growth at constant risk, the accelerated recognition of future loss conditions can induce valuation assessments that are opposed to the entity's enhanced valuation. Supplementary analyses reveal that investors misattribute (some) expected losses to the entity's past performance and rely on unadjusted current summary earnings to assess the entity's prospects. Our findings provide insight into the cognitive processes that lead investors to incorrectly assess earnings trends and inform regulators, standard setters, investors, and preparers that the accelerated recognition of relevant and unbiased forward-looking loss estimates can impair the decision-usefulness of financial statements.

Most replicated genetic determinants for type 1 diabetes are common (minor allele frequency [MAF] >5%). We aimed to identify novel rare or low-frequency (MAF <5%) single nucleotide polymorphisms with large effects on risk of type 1 diabetes. We undertook deep imputation of genotyped data followed by genome-wide association testing and meta-analysis of 9,358 type 1 diabetes case and 15,705 control subjects from 12 European cohorts. Candidate variants were replicated in a separate cohort of 4,329 case and 9,543 control subjects. Our meta-analysis identified 27 independent variants outside the MHC, among which 3 were novel and had MAF <5%. Three of these variants replicated with Preplication < 0.05 and Pcombined < Pdiscovery. In silico analysis prioritized a rare variant at 2q24.3 (rs60587303 [C], MAF 0.5%) within the first intron of STK39, with an effect size comparable with those of common variants in the INS and PTPN22 loci (combined [from the discovery and replication cohorts] estimate of odds ratio [ORcombined] 1.97, 95% CI 1.58–2.47, Pcombined = 2.9 × 10−9). Pharmacological inhibition of Stk39 activity in primary murine T cells augmented effector responses through enhancement of interleukin 2 signaling. These findings provide insight into the genetic architecture of type 1 diabetes and have identified rare variants having a large effect on disease risk.

Published: January 2020

Neste artigo refletimos sobre os registros de representação que intervêm no estudo de curvas e de superfícies, como objetos matemáticos de referência, explorando a técnica Crivo-Geométrico. Para isso, analisamos o software GeoGebra e as práticas de estudantes de um curso de Mestrado em Educação Matemática na resolução de um problema utilizando o ambiente papel/lápis. Os resultados obtidos mostram que os estudantes têm domínio dos seus pensamentos geométricos no tratamento de objetos no plano bidimensional, mas apresentam dificuldades na representação de objetos geométricos no espaço tridimensional, que se manifestam na mobilização inadequada de pensamentos geométricos sobre os crivos de curvas e de superfícies que delimitam o objeto geométrico envolvido no problema, tanto em Geometria Espacial quanto em Geometria Analítica.

The Asteraceae family is one of the largest families, comprising 67 genera and 264 species in Poland. However, only a few genera, including Artemisia, are potential allergenic sources. The aim of the study was to compare the mugwort pollen seasons in Bialystok, Bydgoszcz, Sosnowiec, Lublin, Piotrkow Trybunalski, Opole, Olsztyn, Szczecin, Warsaw and Wroclaw in 2019. The investigations were carried out using the volumetric method. Seasonal Pollen Index was estimated as the sum of daily average pollen concentrations in the given season. The mugwort pollen season is mainly observed in June, July and at the beginning of September. In 2019 the pollen season of mugwort started first in Opole, on the June 26th. At the latest, a pollen season ended in Bydgoszcz and Warsaw, at the end of September. The differences of pollen seasons duration were extremely considerable, from 35 to 83 days. The highest airborne concentration of 97 pollen grains/m3 was noted in Lublin on the July 31st. The maximum values of seasonal pollen count in Polish cities occurred between July 28th and August 12th, most often between in late July and early August. The highest mugwort pollen allergen hazard occurred in 2019 in Lublin, Warsaw, Opole and Wroclaw, and was 2–3 times higher than in other cities. The highest variability in the analysed seasons was found in start date, while the lowest in the peak value and SPI value. In the pollen season in 2019, 2 peaks of Artemisia pollen concentrations were observed as a result of the order of flowering of A. vulgaris and A. campestris. Information on the pollination of various Artemisia species will be used to avoid excessive exposure to allergens of these pollen grains.

The results of the soil-erosion study conducted in the occupied territories of the region (2004-2012) show that all types of erosion, including surface, linear, silt, grass, as a result of the complex geological and geomorphological situation of the Karabakh region and the combined impact of anthropogenic pressure. Wind and military erosion have developed in a wide range and are measured by the following average statistics. Goranboy-40.9%; Tartar - 45.0%; Aghdam - 31.3%; Barda - 23.2%, Yevlakh - 26.4%; Kelbajar - 52.4%; Beylagan - 19.8%; Aghjabadi - 15.7%; Fizuli - 45.7%; Gabriel - 63.3%; Zinc - 57.7%; Qubatly - 44.0%; Lachin - 48.0%; Serum-20.9%; Upper Karabakh - 37.0%, which means that 884,000 ha of agricultural land is in danger of being out of crop rotation.
El lugar de la memoria en el cine de Jonas Mekas
Authors: Acevedo Nieto Javier , Marcos Ramos María
Published: January 2020

El presente artículo aspira a aportar una aproximación a la obra clave de Jonas Mekas En el camino, de cuando en cuando, vislumbré breves momentos de belleza (As I Was Moving Ahead Occasionally I Saw Brief Glimpses of Beauty, Jonas Mekas, 2000) reflexionando en torno al concepto de memoria y su plasmación en el film a través de la idea de espacio y tiempo. Así, partiendo de un análisis de varias secuencias del film, y tomando como referente el discurso de la postmodernidad sobre la memoria y el espacio, se intentará relacionar la obra de Mekas y su discurso sobre la memoria filmada con los postulados de Pierre Nora (1989) o Marc Augé (2000) entre otros. De este modo, el objeto de estudio de la memoria, así como conceptos inherentes al llamado nuevo relato, podrá adquirir una dimensión conceptual más sólida y arrojará luz sobre la obra del director para continuar explorando el rol de Mekas como exponente de la vanguardia experimental en el cine contemporáneo.
Entre el recuerdo y el retorno. Memoria e historia de un fantasma en A ghost story (David Lowery, 2017)
Authors: Iturregui-Motiloa Víctor
Published: January 2020

El presente artículo estudia el tratamiento de la memoria que hace la película A Ghost Story (David Lowery, 2017). Esta obra de David Lowery presenta a un fantasma cubierto por una sábana condenado a volver al mundo de los vivos. Nos interesa responder a la pregunta de cómo el relato pone en forma algunas ideas relacionadas con el tiempo, la muerte y los recuerdos. En esta historia fantasmal se identifican algunos de los motivos recurrentes en el género fantástico o de terror. Sin embargo, estos lugares comunes son reinterpretados y enmarcados en un drama romántico de compleja estructura narrativa. Además, la naturaleza de la fábula implica ciertos problemas relacionados con la temporalidad de la imagen cinematográfica. Nos interesa, por tanto, estudiar los procesos de significación y de persuasión que hacen verosímiles las desventuras de este espectro errante. Para ello se utilizarán dos herramientas metodológicas: el análisis narratológico y el análisis fílmico. Concretamente, nos apoyaremos en los conceptos de orden, duración y frecuencia acuñados por Gérard Genette, localizados en secuencias concretas de la película.

Phase transitions of biological phenotypes by means of a prototypical PDE model
Authors: Mascia C. , Moschetta P. , Simeoni C.
Published: January 2020

The basic investigation is the existence and the (numerical) observability of propagating fronts in the framework of the so-called Epithelial-to-Mesenchymal Transition and its reverse Mesenchymal-to-Epithelial Transition, which are known to play a crucial role in tumor development. To this aim, we propose a simplified one-dimensional hyperbolic-parabolic PDE model composed of two equations, one for the representative of the epithelial phenotype, and the second describing the mesenchymal phenotype. The system involves two positive constants, the relaxation time and a measure of invasiveness, moreover an essential feature is the presence of a nonlinear reaction function, typically assumed to be S-shaped. An identity characterizing the speed of propagation of the fronts is proven, together with numerical evidence of the existence of traveling waves. The latter is obtained by discretizing the system by means of an implicit-explicit finite difference scheme, then the algorithm is validated by checking the capability of the so-called LeVeque–Yee formula to reproduce the value of the speed furnished by the above cited identity. Once such justification has been achieved, we concentrate on numerical experiments relative to Riemann initial data connecting two stable stationary states of the underlying ODE model. In particular, we detect an explicit transition threshold separating regression regimes from invasive ones, which depends on critical values of the invasiveness parameter. Finally, we perform an extensive sensitivity analysis with respect to the system parameters, exhibiting a subtle dependence for those close to the threshold values, and we postulate some conjectures on the propagating fronts.

Abstract. M.V Boelongan shipwreck is an underwater archaeological site which is potential to be a dive spot destination in Mandeh Bay, Pesisir Selatan Regency. The shipwreck has huge historical value as it was used by Dutch during World War II. This study used Geographic Information System (GIS) to conduct the master plan, as an effort to protect the shipwreck from tourism impact. It would also be beneficial for listing tourism assets and modelling a management strategy. GIS itself is a system designed to capture, store, manipulate, analyze, manage, and present all types of geographical data. Assessment and variables scoring from the research location will be conducted to get suitable location for dive spot. To determine the location, the analysis was based on the result of the integration between the assessment and variables scoring which has been determined. The result shows that there are six locations suitable to be dive spot destination. The dive spots with zonation concept would support the preservation of marine environment as well as M.V Boelongan shipwreck as archaeological remains in Mandeh Bay area.Keywords: Management Model, Multidestination, Geographic Information System, Boeloengan Shipwreck, Mandeh Bay  Abstrak.

Abstract. Underwater archaeological research usually talks about archaeological remains under the sea like a sinking ship. The issue of sinking ships concerns the cargo, the type of ship, shipping lines, trade routes, and the origin and technology of shipbuilding. The problem is that archeological findings are not only in the sea, but also in lakes, swamps, or rivers. Therefore underwater archeology not only studies archeological findings in the sea but also on the lake. Archaeological findings originating from within the Matano lake include in the form of pottery both intact and fractions mixed with metal objects. Lake Matano located in Luwu Regency in South Sulawesi is an ancient lake and is the deepest lake in Southeast Asia. How and why these pottery findings arrived inside the lake, are the problems that will be answered in this study. The aim is to find out the function and role of pottery in the sites of Lake Matano and what factors influence it. With the method of inductive reasoning and underwater exploration and land and an analogy with the findings of similar pottery in the terrestrial area of the lake, we can find a connection between the findings of pottery and the same activities related to the manufacture of metal objects, and strong suspicion of tectonic activity that affects the site's existence.Keywords: Pottery, Underwater, Terrestrial, Metal, Lake MatanoAbstrak. Penelitian arkeologi bawah air biasanya berbicara tentang tinggalan arkeologi di bawah laut seperti kapal tenggelam. Isu kapal tenggelam ini menyangkut tentang muatan, jenis kapal, jalur pelayaran, jalur perdagangan, dan asal muasal dan teknologi pembuatan kapal. Permasalahannya, temuan arkeologi tidak saja berada di dalam laut, tetapi juga terdapat di perairan danau, rawa, ataupun sungai. Oleh karena itu, arkeologi bawah air tidak saja mempelajari temuan arkeologi di dalam laut, tetapi juga di danau. Temuan arkeologi yang berasal dari dalam Danau Matano antara lain berupa tembikar, baik utuh maupun pecahan yang bercampur dengan benda logam. Danau Matano yang terletak di Kabupaten Luwu di Sulawesi Selatan adalah danau purba dan merupakan danau terdalam di Asia Tenggara. Bagaimana dan mengapa temuan tembikar ini sampai berada di dalam danau adalah permasalahan yang hendak dijawab dalam penelitian ini. Tujuannya adalah untuk mengetahui fungsi dan peran keberadaan tembikar di situs-situs Danau Matano dan faktor-faktor apa yang mempengaruhinya. Dengan metode penalaran induktif dan ekplorasi bawah air dan daratan serta analogi dengan temuan tembikar serupa di area terrestrial danau dapat diketahui adanya hubungan antara temuan tembikar dengan aktivitas yang sama berkaitan dengan pembuatan benda logam, dan dugaan kuat adanya aktivitas tektonik yang mempengaruhi keberadaan situs.Kata kunci: Tembikar, Bawah air, Terrestrial, logam, Danau Matano

Authors: Pramaresti Elyada Wigati
Published: January 2020

South Nias is one of many regions in Indonesia that still mantains the existence of traditional settlement. Villages found in this regency have unique characteristic as are shown by their linear forms with two rows of houses facing each other. Although the villages seem to have similar forms, in fact, there are three types of spatial patterns which present in South Nias traditional villages. The main purpose of this research relates to the variations of spatial patterns in this region’s traditional settlement. Moreover, its aim is to obtain the classification of settlement forms in South Nias. The research method used to answer the question is qualitative and the data are obtained by field observation, interviews, and literature study. The result reveals that traditional villages in South Nias have spatial patterns in the form of branched linear, I-shaped linear, and T-shaped linear. Classification of the settlement form is based on differences in the shape and location of village materil components. This research also intents to conduct documentation about South Nias traditional villages together with their components which become scarce in present day because damaged by natural factors or deliberately replaced by modern components.Nias Selatan adalah salah satu wilayah di Indonesia yang masih mempertahankan keberadaan permukiman tradisional. Desa-desa yang ditemukan di kabupaten tersebut memiliki karakteristik yang unik, yaitu berbentuk linear dengan dua baris rumah yang saling berhadapan. Meskipun sekilas desa-desa itu tampak memiliki bentuk yang sama, sebenarnya terdapat tiga tipe bentuk tata ruang yang dijumpai pada desa tradisional di Nias Selatan. Permasalahan yang akan dikaji dalam penelitian ini berkaitan dengan variasi bentuk tata ruang permukiman tradisional di wilayah tersebut. Tujuannya untuk memperoleh klasifikasi bentuk permukiman tradisional Nias Selatan. Metode penelitian yang digunakan untuk menjawab permasalahan adalah metode kualitatif dengan pengumpulan data melalui observasi lapangan, wawancara, dan studi literatur. Hasil penelitian menunjukkan desa tradisional di Nias Selatan memiliki bentuk tata ruang linear bercabang, linear I, dan linear T. Klasifikasi bentuk permukiman tersebut didasarkan atas perbedaan bentuk dan keletakan komponen materi desa. Penelitian ini juga berupaya untuk melakukan dokumentasi desa-desa tradisional Nias Selatan beserta komponennya yang kini menjadi langka karena rusak oleh faktor alam maupun sengaja diganti dengan komponen yang modern.
