Starting from a series of speech stimuli representing an F0 peak shift continuum from German early to medial peak, a series of non-speech stimuli is created. These non-speech stimuli show the F0 and intensity courses of the original speech stimuli, but with a constant formant structure. The results of a perception experiment reveal that the organisation of the peak shift continuum found for the...

This paper derives upper and lower bounds on the capacity of the multipleinput single-output free-space optical intensity channel with signal-independent additive Gaussian noise subject to both an average-intensity and a peak-intensity constraint. In the limit where the signal-to-noise ratio (SNR) tends to infinity, the asymptotic capacity is specified, while in the limit where the SNR tends to...

Results of recent perception experiments revealed that the signalling of rising-falling F0 peak categories in German intonation involves an interplay of F0 and intensity. Moreover, combining identification judgements and reaction times suggests that the abruptness of the perceptual change between the categories is determined by the signal dynamics in the sense of the durations of the F0 peak mo...

Plant leaves exhibit differentiated patterns of photosynthesis rates under diurnal light regulation. Maize leaves show a single-peak pattern without photoinhibition at midday when the light intensity is maximized. This mechanism contributes to highly efficient photosynthesis in maize leaves. To understand the molecular basis of this process, an isobaric tag for relative and absolute quantitatio...

This paper presents a wavelet-based Gaussian method (WGM) for the peak intensity estimation of energy dispersive X-ray fluorescence (EDXRF). The relationship between the parameters of Gaussian curve and the wavelet coefficients of Gaussian peak point is firstly established based on the Mexican hat wavelet. It is found that the Gaussian parameters can be accurately calculated by any two wavelet ...

We examined the hypothesis that glucose flux was directly related to relative exercise intensity both before and after a 12-wk cycle ergometer training program [5 days/wk, 1-h duration, 75% peak O2 consumption (VO2 peak)] in healthy female subjects (n = 17; age 23.8 +/- 2.0 yr). Two pretraining trials (45 and 65% of VO2 peak) and two posttraining trials [same absolute workload (65% of old VO2 p...

To test the hypothesis that acute hypoxia does not modify the relationship between plasma vasopressin concentration ([AVP](p)) and plasma osmolality (P(osmol)) during exercise and that the increase in [AVP](p) during exercise is due mainly to the exercise intensity-dependent increase in P(osmol), we examined [AVP](p) during a graded exercise in a hypoxic condition (13% O(2), N(2) balance) in se...

XRD patterns of NIST standard reference materials were collected using a gas proportional detector and a linear Position Sensitive Detector (PSD). Incident beam optics used for data collection consisted of a polycapillary X-ray lens, a graded multilayer parabolic X-ray mirror, and programmable divergence slits. Peak position, width, and intensity were studied with respect to the different exper...
