This paper discusses a data-driven learning (DDL) tool, which consists of a learner corpus for L2 learners of German. The learner corpus, in addition to submissions from ongoing current users, has been constructed from millions of submissions from a variety of activity types of approximately 5000 learners who used the E-Tutor CALL system over a period of five years. By following a cyclical proc...

This paper presents a study of the influence of emotions on the behaviour of an intelligent pathfinding agent. A model of pathfinding is proposed that takes into account the emotional state of the agent. Results show that blindly following the most urgent emotion can lead to degenerate behaviour, and that cross-exclusion can be used to effectively moderate emotional influences. Applications of ...

We introduce our methodology for collecting tweets and identifying event-related actionable information using key terms and inflections. The vast amount of user-generated content makes it challenging to detect relevant information. Therefore, we aim to facilitate extracting morphological, syntactic, and semantic features of a key term semiautomatically. The results of our study show that handli...

Reputation is an essential component of destination competitiveness. The analysis of UGC (“explicit” popularity) and of the engagement generated by these comments (“implicit” popularity”) is usually conducted separately. Monitoring the online performance of a destination require a more comprehensive approach, which combines the capacity to attract tourists’ reviews and to enhance potential visi...

We study baryogenesis through lepton number violation in left-right symmetric models. In these models the lepton number and CP violating interactions of the triplet higgs scalars can give rise to lepton number asymmetry through non-equilibrium decays of the SU(2)L triplet higgs and the right handed neutrinos. This in turn generates baryon asymmetry during the electroweak anomalous processes. Co...

the development of multicomponent reactions (mcrs) designed to produce elaborate biologically active compounds has become an important area of research in organic, combinatorial, and medicinal chemistry. a comparative study of the synthesis of new bis-spiro-oxindolo(pyrrolizidines/pyrrolidines) ring systems by the cycloaddition of azomethine ylides generated by a decarboxylative route from sarc...

Introduction: Ischemia/reperfusion (IR) injury involves a complex interrelated sequence of events. High levels of nitric oxide (NO) are generated with inducible form of nitric oxide synthase (iNOS) leading to the renal IR injury and glutathione (GSH) depletion. The present study was designed to investigate the effect of L-Nil (N6- (1-Iminoethyl)-L- lysine.hydrochloride), a selective inhibito...

A purely inseparable field extension $K$ of a $k$ characteristic $p\not=0$ is said to be $\omega_0$-generated over if $K/k$ not finitely generated, but $L/k$ generated for each proper intermediate $L$. In 1986, Deveney solved the question posed by R. Gilmer and W. Heinzer, which consists in knowing lattice fields an necessarily linearly ordered under inclusion, constructing example where $[k^{p...

background: leishmaniasis is a worldwide disease prevalent in tropical and sub- tropical countries. in the present study the immunogenicity of three human hla-dr1 restricted peptides derived from l. major gp63 protein was evaluated using fvb/n-dr1 transgenic mouse model. methods: the immunity generated by three mhc class ii – restricted peptides with the sequence of aarlvrlaaagaavt (aar), aaplv...

In this paper, two different ways of introducing alternation for lattice-valued (referred to as {L}valued)  regular tree grammars and {L}valued top-down tree automata are compared. One is the way which defines the alternating regular tree grammar, i.e., alternation is governed by the non-terminals of the grammar and the other is the way which combines state with alternation. The first way is ta...
