In Section 2, we give a brief introduction tcl the RS; in Section 3, we introduce an adaptive implemlentation of the RS and derive an approximate expression for convergence time linearized techniques comedy used in the analysis of phase lock loops and other nonlinear circuits; in section 4, we describe a new analog RS circuit with an adaptive tenth-order Butterworth lovv. pass filter (LPF) and ...

ecotourism as the most attractive subset of the tourism industry can contribute to natural resource conservation and local development. although great numbers of people annually visit abbasabad area, in veresk, mazandaran, to enjoy its brilliant landscape and moderate ecologic condition, there is no applicable plan for many natural attractive zones in this area. as a result, some specific well ...

A new feature set for ASR called Rate-Spectrum(RS) is proposed. RS is a spectral representation obtained using a computational auditory model. The feature is noise-robust and considerably speaker invariant. RS matches the smoothed log spectrum both in shape and dynamic range variation. DCT is used to reduce dimensionality. Comparison of the proposed features with MFCC is done using an Isolated ...

Replicative stress (RS) is a type of endogenous DNA damage that cells suffer every time they duplicate their genomes, and which is further boosted by oncogenes. In mammals, the RS response (RSR) is coordinated by ATR and Chk1 kinases. We sought to develop a mammalian organism that is selectively protected from RS. To this end, mice carrying an extra copy of the Chk1 gene were generated. In vitr...

Early life stress (ELS) exerts long-lasting epigenetic influences on the brain and makes an individual susceptible to later depression. It is poorly understood whether ELS and subsequent adult chronic stress modulate epigenetic mechanisms. We examined the epigenetic mechanisms of the BDNF gene in the hippocampus, which may underlie stress vulnerability to postnatal maternal separation (MS) and ...

The Earth’s climate is driven by surface incident solar radiation (Rs). Direct measurements have shown that Rs has undergone significant decadal variations. However, a large fraction of the global land surface is not covered by these observations. Satellite-derived Rs has a good global coverage but is of low accuracy in its depiction of decadal variability. This paper shows that daily to decada...
