GeramiPour, Ph.D. The present study was conducted to investigate the impact of language learning activities on development of spoken language in 5-6-year-old children at private preschool center...

We present a simple method for fully stabilized mid-infrared optical frequency comb generation based on single-pass femtosecond parametric that is seeded by continuous-wave laser. have implemented the in periodically poled lithium niobate crystal produces tunable across 3325 nm–4000 nm (2380 cm−1–3030 cm−1). The generates (idler) with known and Carrier-Envelope Offset (CEO) without need to dire...

We investigate theoretically mid-infrared (MIR) generation via difference frequency in multimode AlGaAs-on insulator (AlGaAs-OI) waveguides. The large refractive index between the AlGaAs core and silica cladding shrinks modes size down to sub- ?m 2 scale, and, together with strong second-order nonlinear polarization, empowers effects. As a result, efficient MIR is obtained few-cm long waveguide...

It has been argued that the actual distribution of word frequencies could be reproduced or explained by generating a random sequence of letters and spaces according to the so-called intermittent silence process. The same kind of process could reproduce or explain the counts of other kinds of units from a wide range of disciplines. Taking the linguistic metaphor, we focus on the frequency spectr...

This paper proposes a method of predicting the formant frequencies of a frame of speech from its mel-frequency cepstral coefficient (MFCC) representation. Prediction is achieved through the creation of a Gaussian mixture model (GMM) which models the joint density of formant frequencies and MFCCs. Using this GMM and an input MFCC vector, a maximum a posteriori (MAP) prediction of the formant fre...

Here we test Neutral models against the evolution of English word frequency and vocabulary at the population scale, as recorded in annual word frequencies from three centuries of English language books. Against these data, we test both static and dynamic predictions of two neutral models, including the relation between corpus size and vocabulary size, frequency distributions, and turnover withi...

This article describes a Windows program that enables users to obtain a broad range of statistics concerning the properties of word and nonword stimuli in Spanish, including word frequency, syllable frequency, bigram and biphone frequency, orthographic similarity, orthographic and phonological structure, concreteness, familiarity, imageability, valence, arousal, and age-of-acquisition measures....
