In this paper, we show that an $L_1$-2-type surface in the three-dimensional hyperbolic space $H^3subset R^4_1$ either is an open piece of a standard Riemannian product $ H^1(-sqrt{1+r^2})times S^{1}(r)$, or it has non constant mean curvature, non constant Gaussian curvature, and non constant principal curvatures.

this paper reports on the findings of a study designed to investigate the cultural and social complexities governing the compliment responses among the persian native speakers. 200 persian respondents took a 24-item discourse completion task (dct) while 15 native field workers were also set responsible for collecting the examples of complimenting exchanges they either observed or participated i...

AIMS To test the hypothesis that exposure to ambient language in the womb alters phonetic perception shortly after birth. This two-country study aimed to see whether neonates demonstrated prenatal learning by how they responded to vowels in a category from their native language and another non-native language, regardless of how much postnatal experience the infants had. METHOD A counterbalanc...

Although the epileptogenic properties of estrogens have been widely demonstrated in several models and species, the mechanism(s) by which estrogens can acutely change seizure parameters including after discharge and seizure duration remain remains to be determined. In the present study, we examined the role of NMDA (N-methyl-D-aspartate), non-NMDA and estrogenic receptors in estradiol benzoate ...

This paper deals with the problem of non-native accents in speech recognition. Reference tests were performed using whole-word and sub-word models trained either with a native accent or a pool of native and non-native accents. The results seem to indicate that the use of phonetic transcriptions for each speci c accent may improve recognition scores with sub-word models. A data-driven process is...

Teachers are the most important players of every educational system in different societies; accordingly, understanding their personal reflections may help us gain valuable insights into what it means to be a teacher in a specific cultural and social context. The purpose of this case study was to investigate the life and career of 6 non-native English speaking teachers in state educational syste...
