- Type:
- model:internalpart and TEXT
- Language:
- English
- Description:
- Two distinct hemocyte populations are determined in the hemolymph of the triatomine bug Triatoma infestans Klug, oenocytoids and plasmatocytes, and their independent origin from separate stem cells is shown. Both hemocyte populations differ considerably in their morphology, ultrastructure and lectin-binding properties. While oenocytoids are quite uniform with easily definable cells which do not to bind any assayed lectin, the plasmatocytes are a very polymorphic population possessing several morphological types and displaying a positive reactivity with lectins.

511923. Two ideals connected with strong right upper porosity at a point
- Creator:

- Type:
- model:article and TEXT
- Subject:
- matematika, mathematics, one-side porosity, local strong upper porosity, completely strongly porous set, ideal, 13, and 51
- Language:
- English
- Description:
- Let SP be the set of upper strongly porous at 0 subsets of \mathbb{R}^{+} and let Î(SP) be the intersection of maximal ideals I\subseteq SP. Some characteristic properties of sets E \in Î(SP) are obtained. We also find a characteristic property of the intersection of all maximal ideals contained in a given set which is closed under subsets. It is shown that the ideal generated by the so-called completely strongly porous at 0 subsets of \mathbb{R}^{+} is a proper subideal of Î(SP). Earlier, completely strongly porous sets and some of their properties were studied in the paper V.Bilet, O.Dovgoshey (2013/2014)., Viktoriia Bilet, Oleksiy Dovgoshey, Jürgen Prestin., and Obsahuje seznam literatury

511924. Two identities related to Dirichlet character of polynomials
- Creator:
- Yao, Weili and Zhang, Wenpeng
- Format:
- bez média and svazek
- Type:
- model:article and TEXT
- Subject:
- Dirichlet character of polynomials, sum analogous to Kloosterman sum, identity, and Gauss sum
- Language:
- English
- Description:
- Let $q$ be a positive integer, $\chi $ denote any Dirichlet character $\mod q$. For any integer $m$ with $(m, q)=1$, we define a sum $C(\chi, k, m; q)$ analogous to high-dimensional Kloosterman sums as follows: $$ C(\chi, k, m; q)=\sum _{a_1=1}^{q}{}' \sum _{a_2=1}^{q}{}' \cdots \sum _{a_k=1}^{q}{}' \chi (a_1+a_2+\cdots +a_k+m\overline {a_1a_2\cdots a_k}), $$ where $a\cdot \overline {a}\equiv 1\bmod q$. The main purpose of this paper is to use elementary methods and properties of Gauss sums to study the computational problem of the absolute value $|C(\chi, k, m; q)|$, and give two interesting identities for it.

511926. Two iron technology diffusion routes in Eastern Europe
- Creator:
- Zavyalov , Vladimir I. and Terekhova, Nataliya N.
- Format:
- bez média and svazek
- Type:
- model:article and TEXT
- Subject:
- archaeometallography, Eastern Europe, ferrous metals, transition period, archeometallografie, východní Evropa, železné kovy, and přechodné období
- Language:
- Czech
- Description:
- Archaeometallographic data suggest that there were two technological models in Eastern Europe as early as the Bronze Age–Early Iron Age transition period (9th–7th centuries BC). We link their development to two routes via which knowledge of use of ferrous metals diffused from Anatolia. The first route reached the North Caucasus, the second route passed through Greece and the Balkans to Central and Eastern Europe. and Archeometalografická data naznačují, že již v přechodu mezi dobou bronzovou a ranou dobou železnou (9.–7. stol. př. n. l.) existovaly ve východní Evropě dva technologické modely zpracování železa. Jejich rozvoj spojujeme se dvěma trasami, kterými se znalosti užívání železných kovů z Anatolie rozšířily. První trasa překročila Zakavkazsko, druhá trasa vedla přes Řecko a Balkán do střední a východní Evropy.

511927. Two languages in one mind: insights into cognitive effects of bilingualism from usage-based approaches

- Subject:
- bilingualism, cognition, cognitive plasticity, executive function, usage-based, bilingvismus, exekutivní funkce, kognice, and kognitivní plasticita
- Language:
- Czech
- Description:
- Bilingualism has been associated with changes in our language-related and domain-general cognition. However, it remains controversial whether bilingualism-related cognitive effects are robust and stable. Also, it is still unclear which aspects of bilingual experiences affect the plasticity of cognitive processes. This article offers a selective overview of the literature on bilingualism and cognition. We discuss results from studies which investigated the sources of cognitive plasticity in bilinguals, using prominent bilingual factors. We argue that, at least in part, the field deals with the controversies by viewing bilingualism through the perspective of usage-based (or experience-based) approaches, although such a link is not always made explicitly. Viewing bilingual variables as indicators of language use and engagement with both languages might offer promising ways forward while allowing for comparisons of existing studies on bilingualism with more recent ones, which build on the usage-based perspective more explicitly. and Bilingvismus je spojován se změnami v kognitivních procesech, a to jak v procesech zodpovědných za jazykové zpracování, tak v doménově obecné kognici. Zůstává však předmětem diskuse, jak silné a stabilní účinky bilingvismu na kognici jsou. Rovněž zůstává nejasné, jaké aspekty bilingvismu jsou primárním zdrojem plasticity kognitivních procesů. Tento článek nabízí výběrový přehled literatury o bilingvismu a kognici a rozebírá existující studie zkoumající zdroje kognitivní plasticity u bilingvních mluvčích z pohledu usage-based přístupů. Zaměřujeme se na roli prominentních bilingvních faktorů, jakými jsou úroveň znalosti jazyka, věk osvojování jazyka, míra střídání kódů, ale také proporcionalita používání jazyků. Tvrdíme, že literatura o vlivu dvojjazyčnosti na kognici se z části vypořádává s kontroverzemi tím, že nahlíží na bilingvismus perspektivou usage-based přístupů, i když spojení s tímto vědeckým rámcem není vždy výslovně zmiňováno. Zasazení bilingvních faktorů do kontextu usage-based přístupů může nabídnout slibné cesty vpřed a zároveň umožnit srovnání stávajících studií o bilingvismu s novějšími studiemi, které jsou ukotveny v usage-based perspektivě explicitněji.

511929. Two lists of Waldensian errors in manuscripts I F 230 and I F 707 in Wrocław University Library

- Type:

- Subject:
- The Waldensians, Articuli secte Waldensium, manuscripts, and Wroclaw University Library
- Language:
- Multiple languages
- Description:
- This paper analyses two lists of errors in the Waldesian cult, as contained in manuscripts I F 230 (from 1399, and its twin manuscript Mil II 58), as well as I F 707 (from the early 15th century). The list in manuscript I F 230 was compiled earlier, whereas the one from manuscript I F 707 is identical with the list included in manuscript No. 229 from the library in Pelplin. The comparison of the anti-heretic lists of errors from manuscripts I F 230 and I F 707, as well as the analysis of their contents, reveals similarities and leads to a conclusion that they both refer to writings by inquisitor Petrus Zwicker, while the list in I F 230 could have been even authored by him.

511930. Two measures for the stability of Extended Fibonacci Cubes
- Creator:

- Format:
- bez média and svazek
- Type:
- model:article and TEXT
- Subject:
- Network topology, neural network architecture, connectivity, quantitative modeling of networks, graph stability, and Extended Fibonacci Cubes
- Language:
- English
- Description:
- The Fibonacci Cube is an interconnection network that gets many desirable properties that are very important in the network design, network stability and applications. The extended Fibonacci Cube is a new network topology. The vulnerability value of a communication network shows the resistance of the network after the disruption of some centres or connection lines until the communication breakdown. In a network, as the number of centres belonging to sub networks changes, the vulnerability of the network also changes and requires greater degrees of stability or less vulnerability. If the communication network is modelled by graph G, the deterministic measures tend to provide a worst-case analysis of some aspects of overall disconnection process. Many graph theoretical parameters have been used in the past to describe the stability of communication networks. There are few parameters such as integrity, neighbour-integrity and tenacity number giving the vulnerability. Also, in the neighbour-integrity, if a station is destroyed, the adjacent stations will be betrayed so that the betrayed stations become useless to network as a whole. In this paper we study the stability of the Extended Fibonacci Cube using the integrity and neighbour-integrity. We compared the obtained results with the results of the other network topologies. We saw that, for two graphs G1 and G2 that have same number of vertices if k(G1) > k(G2), then I(G1) > I(G2) and NI(G1)< NI(G2).
