We present femtosecond studies of photoexcited carrier dynamics in hydrogenated amorphous silicon and silicon-germanium alloys grown by the hot-wire assisted chemical vapor deposition (HWCVD) technique, which is promising for producing high-quality device-grade materials. We have used wavelength-resolved femtosecond pump-probe techniques to study the dynamics of photoexcitations in these materi...

Dielectric-silicon interfaces are becoming ever more important to device performance. Charge inside a surface dielectric layer is neutralized in Si leading an accumulation or inversion of free carriers. Additionally, states at the interface occupied by charges via Shockley-Read-Hall carrier statistics. It accepted that density charge near midgap, which can only reach concentration as high state...

The brooding bivalves, Nutricola tantilla and N. confusa overlap in their geographic distributions, habitats, and modes and timing of reproduction. Based on previous studies we infer that males of both species release spermatozoa into the water column; while females retain developing embryos in a brood chamber. Females release fully formed juveniles and there is no pelagic larval stage. We hypo...

CP measurements show that PBTI stress induced interface trap area density ΔNit in InGaAs/Al2O3 n-MOSFET is very small and has power law time evolution At in the stress phase, and is partially recovered in the recovery phase. However the DC Is-Vg measurements show large degradations of negative ΔVg and sub-threshold swing S in the sub-threshold region and are recovered in the recovery phase, als...

the aim of the present study was to compare the effects of hypericin and fluoxetine in the treatment of companion dogs with tail chasing in ahvaz district. in the present survey, eighteen dogs with tail chasing were assigned into three equal groups for a three-year period. the dogs were randomly classified based on different treatment groups. during 15 weeks, dogs of group a were given 0.05 mg ...

A technique we refer to as Elevation Information in Tail (EIT) has been developed to provide improved lidar altimetry from CALIPSO lidar data. The EIT technique is demonstrated using CALIPSO data and is applicable to other similar lidar systems with low-pass filters. The technique relies on an observed relation between the shape of the surface return signals (peak shape) and the detector photo-...

The popularity of contents on the Internet is often said to follow a Zipf-like distribution. Different measurement studies showed, however, significantly different distributions depending on the measurement methodology they followed. We performed a large-scale measurement of the most popular peerto-peer (P2P) content distribution system, BitTorrent, over eleven months. We collected data on a da...

Measurements of the coherent tune shifts with intensity and of head-tail growth rates have been performed with single proton bunches in the SPS, at 26 GeV. From these measurements, the real and imaginary part of the transverse impedance can be estimated. Together with earlier and future measurements, this will be used to experimentally document and follow up the effect of the impedance improvem...

Most digital waveguide models of woodwind instruments to date have provided only basic control parameters such as frequency, breath pressure, and vibrato. It is clear that if these models are to gain popularity as real-time performance synthesizers or as composition tools, more flexibility is necessary. This paper discusses the implementation of expressive controls for flutter tonguing, growlin...

In a smart solution-processable luminescent poly(norbornene)/oxazine-1 (Ox1) intercalated fluoromica nanohybrid, the supramolecular organization of the Ox1 dyes can be tuned at the nanoscale level and a deep red emission band switched on by inducing a phase segregation of aligned molecules within the fluoromica layered scaffold. By combining low-temperature photoluminescence and ultrafast pump-...
