During waning flood flows in gravel-bed streams, finegrained bedload sediment (sand and fine gravel) is commonly winnowed from zones of high shear stress, such as riffles, and deposited in pools, where it mantles an underlying coarse layer. As sediment load increases, more fine sediment becomes available to fill pools. The volume of fine sediment in pools can be measured by probing with a metal...

We estimate the power spectrum of HI intensity fluctuations for a sample of 8 galaxies (7 dwarf and one spiral). The power spectrum can be fitted to a power law PHI(U) = AU α for 6 of these galaxies, indicating turbulence is operational. The estimated best fit value for the slope ranges from ∼ −1.5 (AND IV, NGC 628, UGC 4459 and GR 8) to ∼ −2.6 (DDO 210 and NGC 3741). We interpret this bi-modal...

The major problem of indoor localization is presence of Non-line-of-sight (NLOS) channels. In order to perform NLOS identification, in this paper, we propose a novel NLOS identification technique based on threshold selection using the ratio of kurtosis and maximum slope of energy block of the received signal using energy detector. In particular, IEEE 802.15.3c 60 GHz channel models are used as ...

Glucose-induced insulin secretion from pancreatic &cells is known to involve an influx of calcium through voltage-dependent Ca channels. Recently we have recorded singlechannel currents flowing through &cell Ca channels using the outside-out configuration of the patch-clamp technique and Ba2+ as the charge carrier.' Only one type of Ca channel was observed. This had a single-channel slope condu...

The global variability of ultra-thin body and buried oxide (UTBB) MOSFETs in subthreshold and off regimes of operation is analyzed. The variability of the off-state drain current, subthreshold slope, drain-induced barrier lowering (DIBL), gate leakage current, threshold voltage and their correlations are considered. Two threshold voltage extraction techniques were used. It is shown that the tra...

High mobility channel thin-film-transistor (TFT) is crucial for both display and future generation integrated circuit. We report a new metal-oxide TFT that has an ultra-thin 4.5 nm SnO2 thickness for both active channel and source-drain regions, very high 147 cm(2)/Vs field-effect mobility, high ION/IOFF of 2.3 × 10(7), small 110 mV/dec sub-threshold slope, and a low VD of 2.5 V for low power o...

Epitaxially grown, 2.4-microm-thin layers of KY(WO(4))(2):Gd(3+), Lu(3+), Yb(3+), which exhibit a high refractive index contrast with respect to the undoped KY(WO(4))(2) substrate, have been microstructured by Ar beam milling, providing 1.4-microm-deep ridge channel waveguides of 2 to 7 microm width, and overgrown by an undoped KY(WO(4))(2) layer. Channel waveguide laser operation was achieved ...

In this paper, quantum mechanical effects on nanoscale MOSFET devices are investigated through compact physical models. These models cover quantum mechanical influences on device parameters including long-channel threshold voltage shift, gate capacitance degradation, deteriorated short channel effects and sub-threshold slope. In-depth understanding of device characteristic modification brought ...

Iterative threshold decoding of product and parallel concatenated block codes based on one step majority logic decodable (OSMLD) codes has proven to perform remarkably well on AWGN channels. For these codes to be applicable in wireless environment, their performance on fading channels must be examined. The purpose of this work is to study the performance of our iterative threshold decoding algo...
