in view of the fundamental role of genetics in development of obesity, the present study aimed to investigate the single nucleotide polymorphism of some obesity-related genes among a subset of obese women living in tabriz, iran. for this purpose, 70 eligible obese women (aged 18-45 years) were genotyped for the uncoupling protein-1 (ucp-1) -3826a>g, ß3-adrenergic receptor (ß3adr) trp64arg, lept...

Much psychophysical evidence has indicated that the human visual system contains a number of independent mechanisms. each selectively sensitive to a narrow band of spatial frequencies [see Braddick et al.. (1979) for a complete review]. The existence of such a “multiple channei” visual system was first suggested by Campbell and Robson (1968) who based their inference on the relative detectabili...

This paper proposes using a hidden Markov model (HMM) to model a speech signal in terms of its speech class (voiced, unvoiced and nonspeech) and for voiced speech its fundamental frequency. States of the HMM represent unvoiced speech and nonspeech with multiple voiced states that model different fundamental frequencies. The transition matrix of the HMM models temporal changes in speech class an...

In one-dimensional Lie algebraic framework, we calculated the vibrational frequencies of oxygen difluoride (F2O) molecule in fundamental mode, higher overtones and their combinational bands.

Multiple expansion points are introduced to the multiport Cauer ladder network method realize an efficient model order reduction of eddy-current field. The proposed can set multiple target frequencies cover a wide frequency range with small number electric elements. A time-dependent response pulsewidth-modulation (PWM) excitation is accurately reconstructed by setting at both fundamental and ca...

During a Type-I burst, the turbulent deflagation front may excite waves in the neutron star ocean with frequencies, ω ∼ 1 Hz. These waves are observed as highly coherent flux oscillations during the burst. The frequencies of these waves changes as the upper layers of the neutron star cool which accounts for the small variation in the observed QPO frequencies. In principle several modes could be...

Metformin is one of the important anti-diabetic drugs to treat non-insulin dependent diabetes mellitus (NIDDM). Fourier transform infrared (FTIR) and Fourier transform Raman (FTR) spectra of metformin have been used for the molecular study. A satisfactory band assignment has been made on the fundamental modes of vibration. Employing the molecular mechanics method using MM3 force field, the theo...

The authors have been involved in a series of studies showing that the fundamental frequency of a complex tone, the center frequency of a noise band, or the cut-off frequencies of simultaneously presented highand low-passed noise bands, systematically affect the elevation of auditory images – such that high frequencies are associated with high elevations, and low frequencies with low elevations...
