Noisy listening conditions remain challenging for most cochlear implant patients. The present study simulated the effects of decay rates of excitation spread in cochlear implants on the intelligibility of Mandarin speech in noise. Mandarin sentence and tone stimuli were processed by noise-vocoder, and presented to normal-hearing listeners for identification. The decay rates of excitation spread...

their discussion, the authors refer to studies that showed that the decay rate of standing dead wood is slower than dead wood in contact with the forest floor. This contributes to explain the absence of clear differences in properties in classes 1-3. The same argument might potentially be used to explain the differences in decay rates of larch and spruce. Assessing the time elapsed standing of ...

The effects of temperature, salinity and clay particles on the inactivation and decay of the cold-active Bacteriophage 9A, isolated from particle-rich Arctic seawater, were examined using a plating technique to evaluate infectivity (inactivation) and epifluorescence microscopy to measure phage concentrations (decay). Phage 9A was rapidly inactivated over a temperature test range of 25 to 55°C i...

The regulation of miRNAs is critical to the definition of cell identity and behavior in normal physiology and disease. To date, the dynamics of miRNA degradation and the mechanisms involved in remain largely obscure, in particular, in higher organisms. Here, we developed a pulse-chase approach based on metabolic RNA labeling to calculate miRNA decay rates at genome-wide scale in mammalian cells...

In this article, we consider a Cauchy problem for a viscoelastic wave equation of fourth order. Under suitable conditions on the initial data and the relaxation function, we show that the rate of decay is exponential.

In this article we consider a Cauchy problem of a nonlinear viscoelastic equation of order four. Under suitable conditions on the initial data and the relaxation function, we prove polynomial and logarithmic decay of solutions.

Intense vortices in the atmosphere and ocean exhibit a high degree of axisymmetry despite persistent asymmetric forcing from their environment. To further elucidate vortex axisymmetrization a variety of idealized initial-value models for barotropic non-divergent flow is considered. To ensure basic understanding, disturbance evolution is first examined in a rectilinear system of simple shear. Pa...

The Cauchy problem is considered for the massive Dirac equation in the non-extreme Kerr–Newman geometry, for smooth initial data with compact support outside the event horizon and bounded angular momentum. We prove that the Dirac wave function decays in L∞loc at least at the rate t−5/6. For generic initial data, this rate of decay is sharp. We derive a formula for the probabilityp that the Dira...
