Proceedings of the 19th Annual International Conference of the IEEE Engineering in Medicine and Biology Society. 'Magnificent Milestones and Emerging Opportunities in Medical Engineering' (Cat. No.97CH36136), 1997

Chronobiology, which studies periodic patterns or rhythms in living beings, often needs to characterize the observed chronobiological time series (CTS) and to study the stability and adaptability of the periodic patterns in different environmental conditions. Fourier transform (FT) based methods and the complex demodulation (CD) approach have been widely used in such studies. However, the former lacks temporal resolution and ...


Electronic Simulation of Daily Rhythm in Nocturnal Animals

IEEE Transactions on Bio-medical Electronics, 1963

The term biological clock is used to designate the phenomenon, displayed by organisms, of pacing activity in a cyclic manner related to environment. Many nocturnal animals, for example, are capable of entraining the onset of their activity with the light-to-dark transition in a periodic light-dark regime in which the period or ratio of light to darkness varies widely.

The use of sinusoidal models can lead to misleading results and the methods based on a model of multiple sinusoidal components present several problems. These methods are usually based on trying different combinations of frequencies to look for the best model. In the current linear ...

  • Evaluation of nano biological clock activity capsulated by lipid layer

    In this paper, we try to establish newly technique that the components of the biological clock are reconstituted into the liposome. In other words, we try to produce a nano size clock, capsulated into the liposome, made by protein molecules. The circadian clock is a basic cellular system found in almost all organisms. This clock generates self-sustained oscillations under constant conditions with a ≈ 24-hour (circadian) period. In cyanobacteria, circadian clock could be reconstituted in vitro only by mixing the three clock proteins, KaiA, KaiB, KaiC, with adenosine triphosphate (ATP). So we reconstitute these proteins and adenosine triphosphate (ATP) into phospholipid-coated microdroplet and confirmed the clock function. The clocks in phospholipids- coated microdroplet indicate long period more than 24 hour. In this case, period length became 35 hour, self-sustaining oscillation was reaming with little dumping. To reveal why the time cycle became long period, we observed localization of Kai proteins in droplets by using fluorescents labeled Kai proteins under fluorescent microscopy.

  • Characterization of the chronobiological signals based on the continuous wavelet transform

    Chronobiology, which studies periodic patterns or rhythms in living beings, often needs to characterize the observed chronobiological time series (CTS) and to study the stability and adaptability of the periodic patterns in different environmental conditions. Fourier transform (FT) based methods and the complex demodulation (CD) approach have been widely used in such studies. However, the former lacks temporal resolution and the later needs to extract the temporal behaviors of individual frequencies. In this paper, we propose a new approach to characterize the CTS based on the continuous wavelet transform (CWT). It allows us to investigate the time-frequency dynamics of different rhythmic-band activities in the CTS simultaneously. Two application results are presented to illustrate the proposed method.

  • Electronic Simulation of Daily Rhythm in Nocturnal Animals

    The term biological clock is used to designate the phenomenon, displayed by organisms, of pacing activity in a cyclic manner related to environment. Many nocturnal animals, for example, are capable of entraining the onset of their activity with the light-to-dark transition in a periodic light-dark regime in which the period or ratio of light to darkness varies widely. This paper presents the development of an electronic model for simulation of the adaptation of the endogenous circadian rhythm of nocturnal animals due to light stimuli.

  • Automatic nonlinear modeling of multiperiodic biomedical variables with unequidistant sampling

    Estimation of multiple frequencies In biomedical variables with unequidistant sampling is not a straightforward issue. The use of sinusoidal models can lead to misleading results and the methods based on a model of multiple sinusoidal components present several problems. These methods are usually based on trying different combinations of frequencies to look for the best model. In the current linear algorithms, the trial frequencies must be chosen a priori. A trade-off solution must be adopted, because with a high number of frequencies the candidates are close to the spectral peaks, but the probability of detection is low for a fixed probability of false detection. In practice it is not possible to know a priori which is the best set of trial frequencies. On the other hand, the multiple tests problem that arises when multiple frequencies are statistically checked is often ignored. We propose a new nonlinear procedure to estimate automatically a model of multiple sinusoidal components that overrides these problems. This procedure uses nonlinear regression to choose directly the spectral peaks as trial frequencies, increasing in this way the probability of detecting a true component. On the other hand, the problem of multiple tests is managed with a simple statistical technique.

  • Predictable time structure of cardiovascular characteristics in human pregnancy

    A predictable time structure is here quantified by least-squares fitting and polynomial regression in parameters of blood pressure automatically monitored throughout pregnancy in 156 healthy women as well as in 79 women with gestational hypertension or preeclampsia. The results suggest new endpoints to be used for an early identification of gestational hypertension or even preeclampsia.

  • A Study on the Model for Psychological Motives of Compulsive Buying Online in China

    Most prior researches of compulsive buying focused on compulsive purchase behavior offline. This paper, combining with the specific consumer culture in China, constructed and tested a model of psychological motives of compulsive buying online(CBO). The results confirmed previously documented point that materialistic value and psychological motives significantly affect compulsive buying tendency online (CBTO). Our extra findings were that: (1) materialistic value mediates the relationship between psychological motives and compulsive buying tendency online. (2) Psychological motives contain virtual experience motives other than emotional-related and identity-related motives. This paper is a new expansion of the study on psychological motives of compulsive buying and it provides some guiding significance for e-commerce practice.

  • Shiftwork, work scheduling and their impact upon operators in nuclear power plants

    The author notes that the risk for operator error may increase during the night shift due to the influence from circadian rhythms, with variations in alertness and performance efficiency. The author considers some of the factors that have been shown to have a major impact on the adjustment to shiftwork at nuclear power plants, with particular emphasis on the design of the shift schedule. It is suggested that improvements in incident reporting systems and incident analyses may insure that the proper remedies are applied to problems associated with 24-hour operations. The existing body of knowledge from applied shiftwork research is considered in relation to present practices.<<ETX>>

  • Ubiquitous Computing and Time Dimension

    Ubiquitous computing (UbiCom) research has produced a substantial body of work dealing with smart devices, smart environments and smart interaction technologies. However, there are a few initiatives into conceiving and building smart operating systems. In our point of view, providing the software layer the possibility of sensing time flow plays an important role in conceiving a smart operating system framework for UbiCom environments. This work presents a knowledge based operating system (KBOS) and discusses the time dimension that is provided in order to enable the entire system to perceive the time flow - as a biological clock in human beings.

  • Multidimensional analysis of phonological degeneration in pathological voices

    The degree of phonological degeneration of the voices of 68 subjects (35 healthy and 33 suffering from some laryngeal pathology) has been studied by analysing various features of the respective voice signals. Seven parameters were extracted from the Spanish vowel /a/, and the extent to which the corresponding features of the voice signal were affected by pathological conditions was evaluated. The perturbations of intensity seemed to be the most usual characteristics of pathological voices.
