Techniques such as detrended fluctuation analysis (DFA) and its extensions have been widely used to determine the nature of scaling in nucleotide sequences. In this brief communication we show that tandem repeats which are ubiquitous in nucleotide sequences can prevent reliable estimation of possible long-range correlations. Therefore, it is important to investigate the presence of tandem repea...

abstract background and aim: regard with the importance of balance in daily activities especially in sport activities and understanding the important factor affecting it, the purpose of this study was to compare the role of vision system on dynamic postural stability of young women with men elite athletes. materials and methods: twenty six young women and men elite swimmer were chosen from the ...

Travoprost is a prostaglandin analog used in the management of glaucoma and ocular hypertension for reducing intraocular pressure (IOP). The IOP-lowering efficacy of travoprost has been shown to be similar to that of other prostaglandins, including latanoprost and bimatoprost. When compared with fixed combinations of timolol and either latanoprost or dorzolamide, travoprost alone can reduce mea...

negative and therefore the fluctuation of the readings reduced to normal pressure is only statistical. There is no indication of a systematic variation due to causes other than variation of pressure. Since the statistical fluctuation is large it cannot be excluded that systematic variations with amplitudes much smaller than the barometric fluctuation occur but are masked by the statistical fluc...

Functional magnetic resonance imaging (fMRI) has been shown to detect the specificity of acupuncture points, as proved by numerous studies. In this study, resting-state fMRI was used to observe brain areas activated by acupuncture at the Taichong (LR3) acupoint. A total of 15 healthy subjects received brain resting-state fMRI before acupuncture and after sham and true acupuncture, respectively,...

background: although visual impairment of drivers is a very important risk factor for car accident, a few published papers have explored this issue in iran. this study aims to evaluate the visual fitness of public vehicle drivers in kerman province, southeast of iran. methods: a total of 4,003 public vehicle drivers were examined by one ophthalmologist for visual fitness in kerman province betw...

This paper concerns with two reasons for stock price fluctuation, the instinctive stochastic fluctuation and the fluctuation caused by the spread of information. They are constructed by compound Poisson process and continuum percolation model separately. Combining the two models, the authors get a Lévy process for the price fluctuation that can explain the fat-tail phenomenon in stock market. T...

To determine whether rod-mediated vision in goldfish is regulated by a circadian clock, absolute threshold was measured psychophysically in animals maintained in constant darkness. Responses were recorded approximately every 4 hr to a diffuse 532 nm stimulus, 5 sec in duration, with no background light present. Visual threshold tended to be lowest at the time of transition from light to dark, a...
