The circadian clock mechanism in mammals involves two interlocking transcriptional feedback loops. Rev-erb alpha, through its role as a transcriptional repressor, was thought to be the primary determinant of the feedback loop that regulates Bmal1 transcription. Results reported by Sato et al. in this issue of Neuron now show that the transactivator Rora acts coordinately with Rev-erb alpha and ...

This paper provides new insights into the problem of selecting filter center frequencies for the auditory filterbanks. We propose to use a constant frequency distance and a consistent frequency coverage as the two metrics that motivate the logarithmic frequency scaling and a regularized selection of center frequencies. The frequency scaling and the consistent frequency coverage have been derive...

Listening experiments were made to measure the detection thresholds for initial pitch glides in string instrument sounds, where a rapid decline of pitch is caused by tension modulation during the attack. Realistic sounding synthetic tones were generated by additive synthesis. The frequency decay of the glide was defined through the overall decay rate of amplitude, simulating the behavior of rea...

Frequency analyzer is one of the important functions of peripheral auditory system. Psycho-acoustically this gives rise to the concept of critical band, which represents the frequency resolution of the auditory system. Mel-Scale warping is one of the common techniques used for the analysis in speech recognition. Bark and ERB (Equivalent Rectangular Bandwidth) rate scales are two other auditory ...

In this contribution we give a short overview of the situation in the precision calculation of the Bhabha process and we present a preliminary numerical result on the second-order sub-leading correction to the small angle Bhabha process.

Neuronal expression of vasopressin messenger RNA (mRNA) and peptide has been shown to be estrogen dependent. A 5.5-kb genomic DNA fragment, 59 of the AVP coding region, was used in luciferase reporter assays to measure transcriptional activation by either estrogen receptor a or b in response to various treatments. ERa and ERb displayed differential regulation of the AVP promoter. SK-N-SH cells ...

| This paper presents a novel control architecture for a car-like vehicle moving in a dynamic and partially known environment. The key idea is to plan and carry out sensor-based manoeuvres. The paper focuses on the reactive part of the architecture that features control experts, i.e. parameterized control programs adapted to a speciic manoeuvre and capable to react in real-time to unforeseen ev...
