Sleep is not a luxury,but it is a necessity.If people sleep well,they will be more productive and start the morning in an excellent mood.On the other hand,people who do not sleep well,they start their morning very drowsy irrespective of the other effects on their health,such as the disturbance of the circadian rhythm.In this paper,an automatic hybrid algorithm is developed to analyze sleep quality using basically the electroencephalogram(EEG)signal and polysomnographic report.The idea behind this is to perform the EEG signal processing in such a way as to be classified according to the sleep stages.Finally,we check if the subject passed through all the sleep cycles or not.To carry out this work,Python version 3 was used. 展开更多

Driven by many applications in a wide span of scientifc fields,a myriad of advanced ultrafast imaging techniques have emerged in the last decade,featuring record-high imaging speeds above a trllion-frame-per-second with long sequence depths.Although bringing remarkable insights into various ultrafast phenomena,their application out of a laboratory environment is however limited in most cases,either by the cost,complexity of the operation or by heavy data processing.We then report a versatile single-shot imaging technique combining sequentially timed lloptical mapping photography(STAMP)with acousto-optics programmable dispersive fhItering(AOPDF)and digital in-line holography(DIH).On the one hand,a high degree of simplicity is reached through the AOPDF,which enables full control over the acquisition parameters via an electrically driven phase and amplitude spectro-temporal tailoring of the imaging pulses.Here,contrary to most single-shot techniques,the frame rate,exposure time,and frame intensities can be independently adjusted in a wide range of pulse durations and chirp values without resorting to complex shaping stages,making the system remarkably agile and user-friendly.On the other hand,the use of DIH,which does not require any reference beam,allows to achieve an even higher technical simplicity by allowing its lensless operation but also for reconstructing the object on a wide depth of field,contrary to classical techniques that only provide images in a single plane.The imaging speed of the system as well as its flexibility are demonstrated by visualizing ultrashort events on both the picosecond and nanosecond timescales.The virtues and limitations as welll as the potential improvements of this on-demand ultrafast imaging method are critically discussed. 展开更多
