We characterize transversality, non-transversality properties on the moduli space of genus 0 stable maps to a rational projective surface. If a target space is equipped with a real structure, i.e, antiholomorphic involution, then the results have real enumerative applications. Firstly, we can define a real version of Gromov-Witten invariants. Secondly, we can prove the invariance of Welschinger...

In this paper, firstly we find the best constant for a convolution problem on the unit circle via a variational method. Then we apply the best constant on a nonlinear rod equation to give sufficient conditions on the initial data, which guarantee finite time singularity formation for the corresponding solutions.

A class of monoorganoimido-substituted hexamolybdates containing a pyridine group have been firstly synthesized. Furthermore, a reaction protocol of alkylation based on the resulting pyridine-functionalized hexamolybdates has been developed, with which a type of zwitterionic clusters has been successfully obtained.

We examined a method for extracting the low frequency important single-word terms from domain specific text. Firstly, domain-relevant fragments were extracted from the text with the help of a dependency tree. Then the fragments were clustered and candidate terms were defined using the semantic classifier. The studies suggest that this approach allows extracting even terms with a single occurrence.

In this paper, we further investigate the constructions of fuzzy connectives on a complete lattice. We firstly illustrate the concepts of left (right) semi-uninorms and implications satisfying the order property by means of some examples. Then we give out the formulas for calculating the upper and lower approximation implications, which satisfy the order property, of a binary operation.

The evaluation of control performance by means of performance indices from large amounts of measurement data is investigated. The focus is twofold: Firstly to assess information that can be deduced from many data sets and secondly to investigate the usefulness of simple performance measures. Established methods and some useful new ideas are evaluated on many industrial data sets and the results...

This work describes a voltammetric electronic tongue, in which the quantitative information contained in voltammograms obtained from amperometric sensors is firstly extracted employing the discrete wavelet transform (DWT) and then processed employing artificial neural n i e D i o B ©

We firstly employ the fixed point theory to study the stability of cellular neural networks without delays and with time-varying delays. Some novel and concise sufficient conditions are given to ensure the existence and uniqueness of solution and the asymptotic stability of trivial equilibrium at the same time. Moreover, these conditions are easily checked and do not require the differentiabili...

Software engineering is forecast to be among the fastest growing employment field in the next decades. The purpose of this investigation is two-fold: Firstly, empirical studies on the personality types of software professionals are reviewed. Secondly, this work provides an upto-date personality profile of software engineers according to the Myers–Briggs Type Indicator. r 2002 Elsevier Science L...

In this introductory article, the context, history and definitions around Mobile Assisted Language Learning (henceforth, MALL) are discussed. Firstly, some definitions, some classifications and some challenges are presented to help the readers appreciate what they are about to find. Then, the contents of this issue are described and commented, and a brief final remark is provided on its underly...
