The objective of the present study is the development of an automated computerized system that will assist the early diagnosis of fetal hypoxia. We demonstrate that it is possible to distinguish between healthy subjects and acidemic fetuses by way of wavelet transform analysis of the fetal heart rate recordings and fetal pulse oximetry (FSpO2). We focus on the values of the standard deviation o...
objective: electroporation is the most common method used for the transfection of dna. although this method has been attributed for various cell using different buffer compositions, the effects of dna concentration on the transfection efficiency has not yet been studied. here the correlation between the efficiency of electroporation reaction and increments of dna concentration has been investig...
with the growth of more humanistic approaches towards teaching foreign languages, more emphasis has been put on learners’ feelings, emotions and individual differences. one of the issues in teaching and learning english as a foreign language is demotivation. the purpose of this study was to investigate the relationship between the components of language learning strategies, optimism, duration o...
Epilepsy surgery depends on reliable pre-surgical markers of epileptogenic tissue. The current gold standard is the seizure onset zone in ictal, i.e. chronic, electrocorticography recordings. Single pulse electrical stimulation can evoke epileptic, spike-like responses in areas of seizure onset also recorded by electrocorticography. Recently, spontaneous pathological high-frequency oscillations...
objective: the objective of this study was to investigate the invitro fluoride release of four new self-adhesive resin cements; set (sdi, australia), breeze (pentron, usa), embrace wetbond (pulpdent, usa), g-cem (gc, japan) and to assess the bonding performance of these self-adhesive resin cements for bonding of orthodontic brackets. materials and methods: for fluoride release experiment, six ...
toury (1978:200) believes that translation is a kind of activity which inevitably involves at least two languages and two cultural traditions. being polite while asking for something takes place differently in different cultures and languages, therefore various strategies may be applied for making requests and also translation of them in order not to disturb or threaten the face or better to sa...
Several studies showed a positive association between heart rate and pulse wave velocity, a sensitive marker of arterial stiffness. However, no study involving a large population has specifically addressed the dependence of pulse wave velocity on different components of the cardiac cycle. The aim of this study was to explore in subjects of different age the link between pulse wave velocity with...
The investigation of the local properties of an optical field requires its representation in phase space. Recently optical wavelet analysis has been used for the investigation of inhomogeneous fields [1, 2]. Mostly, one prefers to consider intensity distributions, which can easily be measured in optics. Unfortunately, scalograms (squared moduli of the wavelet transform) are not invertible in ge...
Today’s advanced LiDAR systems are able to record the entire laser echo pulse, provided that sufficient data storage is available on the airborne platform. The recorded echo pulses, frequently called waveform data or full-waveform, can then be used to analyze the properties of the reflecting surface, such as classifying objects based on their material signatures; for example, land classificatio...
