Simple Recurrent Networks (SRNs) have been widely used in natural language processing tasks. However, their ability to handle long-term dependencies between sentence constituents is somewhat limited. NARX networks have recently been shown to outperform SRNs by preserving past information in explicit delays from the network’s prior output. However, it is unclear how the number of delays should b...

Abstract—This paper presents an optimization method for reducing the number of input channels and the complexity of the feed-forward NARX neural network (NN) without compromising the accuracy of the NN model. By utilizing the correlation analysis method, the most significant regressors are selected to form the input layer of the NN structure. An application of vehicle dynamic model identificati...

The pLE2SCX vector was developed for the stable expression of exogenous genes in the protozoan parasite Leishmania. The pLE2SCX construct contains three independent selection markers: herpes simplex virus thymidine kinase (HSV-TK), cytosine deaminase (CD) and streptothericin acetyltransferase gene (sat) in multiple cloning site, flanking by 5’ and 3’ untranslated regions of the previously clone...

Classic spatial cueing experiments have demonstrated that salient cues have the ability to summon attention as evidenced by performance benefits when the cue validly indicates the target location and costs when the cue is invalid. Here we show that nonsalient cues that are associated with reward also have the ability to capture attention. We demonstrate performance costs and benefits in attenti...

OBJECTIVE To review current knowledge about the use of exogenous surfactants in the treatment of different lung diseases causing acute respiratory failure in children. SOURCE OF DATA This review is based on the author's experience and on recent data retrieved from ONIA, Mdconsult, Medline and the Cochrane Database Library. SUMMARY OF THE FINDINGS In spite of the success of the use of exogen...

such as pregnant mare serum gonadotropin (PMSG) and human menopausal gonadotropin (hMG) is a well-established practical technique. The purpose of this technique is to achieve enhanced commercial production of genetically meritorious individuals in the livestock industry, to retrieve a number of oocytes and early embryos in various research fields including genetic engineering, and to treat medi...

Attentional shifts can be produced by external (exogenous) cues. Here we focus on whether a shift of attention modulates affective responses. In five experiments, the peripheral onset of an uninformative cue was followed by a novel abstract pattern. We observed that exogenous cuing enhanced target discrimination (RTs) and preference formation (ratings) (Experiment 1a). We therefore distinguish ...

I consider a modified version of the chain store game in which the short-run competitors receive noisy signals of the long-run incumbent firm’s type. The history of signals is observable to the competitors but not to the incumbent. There are two main results. First, for any p ∈ (0, 1) there exists a T < ∞ such that within T periods the competitors assign belief p to the incumbent’s realized typ...
