In Reply: The comments of Dr Wiwanitkit are well taken. In our article (1), our main concern was to emphasize the big difference between plagiarism of ideas and plagiarism of text, especially in scientific writing, where we believe text is just a transfer medium for ideas, which are the essence of scientific work (2-5). Paraphrasing of a scientific text is not always easy, if possible at all (6...

Gold nanoparticles, particularly with the particle size of 2–5 nm, have attracted increasing research attention during the past decades due to their surprisingly high activity in CO and volatile organic compounds (VOCs) oxidation at low temperatures. In particular, CO oxidation below room temperature has been extensively studied on gold nanoparticles supported on several oxides (TiO2, Fe2O3, Ce...

1.1 Background Since Steven Abney's 1987 MIT dissertation, The English Noun Phrase in Its Sentential Aspect, the socalled DP Hypothesis has gained acceptance in the eld of Government and Binding (GB) syntax. This hypothesis proposes that a nominal expression is headed by a determiner that takes a noun phrase as its complement. The preexisting NP Hypothesis, on the other hand, diagrams nominal e...

Since Bolinger’s [1] discovery that pitch cues accentual prominence in English, a tension has arisen between two strategies: equating accent with pitch excursions and relying on perception for identifying accented words. This paper investigates the relation between prominence judgments from untrained listeners and accentual labels produced by trained transcribers. Naïve speakers of English, Spa...

We performed a cognitive experiment in order to obtain evidence that prosody is used for the segmentation of continuous speech for understanding in real time. We assume that the cognitive unit in Japanese speech is the accentual phrase (AP) which is represented by low and high pitch patterns according to the Japanese accent rule. Meaningless speech which consisted of two APs was used as the exp...

This study gives an inside view of the application of ARIMA time series model to forecast the future Gold price in Indian browser based on past data from November 2003 to January 2014 to mitigate the risk in purchases of gold. Hence, to give guideline for the investor when to buy or sell the yellow metal. This financial instrument has gained a lot of momentum in recent past as Indian economy is...

We have bridged a pair of gold electrodes with various arrangements of gold nanoparticles stabilized with citrate molecules. The resulting devices exhibited current fluctuations at a constant bias voltage and fluctuations of the differential conductance as a function of the bias voltage. These fluctuations were attributed to the interplay of molecular conformation, charge switching, and breakin...

Recent progress in the understanding of the fascinating catalysis of CO combustion by supported gold particles is summarized. Focusing on size-selected gold clusters consisting of only a few atoms, that is, the size regime with properties nonscalable from the bulk properties, we discuss the current knowledge of the different factors controlling the reactivity at the molecular level. These facto...
