We fabricated coplanar homojunction a-IGZO TFTs that are highly stable under AC and DC bias-temperature-stress. For TFTs of the size W/L = 60μm/10μm, the stress-induced threshold voltage shifts are all within -0.35 V. A comprehensive investigation of AC BTS stress polarity, pulse width, and duty cycle dependence is presented. We find that higher frequency of bipolar AC pulses increases the devi...

A quasi-equilibrium mass transport analysis has been developed to quantitatively explain the solubility-permeability interplay that exists when using cyclodextrins as pharmaceutical solubilizers. The model considers the effects of cyclodextrins on the membrane permeability (P(m)) as well as the unstirred water layer (UWL) permeability (P(aq)), to predict the overall effective permeability (P(ef...

Severe heat waves have occasionally led to catastrophic avian mortality in hot desert environments. Climate change models predict increases in the intensity, frequency and duration of heat waves. A model of avian evaporative water requirements and survival times during the hottest part of day reveals that the predicted increases in maximum air temperatures will result in large fractional increa...

126 abstract: in this research we studied the effects of cyclic hydration and dehydration of cysts of artemia urmiana and artemia parthenogenetica on the hatching percentage, survival and growth. the experiment was carried out in 3 treatments (1-3 hydration/dehydration cycles) with 3 replicates for each treatment. later effects of cold preservation at -20°c during three time periods were ...

This research aims to study jet downstream scour model under the influence of changes of water level. It also studies and analyzes different parameters and components of diffusion of submerged jet flow in an acceptor fluid and scour hole dimensions. To achieve the objectives, a physical model was made in proportion to the research title. With the Froude number increasing in a nozzle discharge, ...

 In this paper, we calculate the spin-dependent conductance of ferromagnetic quantum wire in the presence of one or two defects by using Green's function method at the tight-binding approach. We study the effect of rotation of defect magnetic moment on the system conductance. The results show that in the magnetic wire, independent of existence or absence of defect, the allowed energy region shi...

Redshifts are given for 50 brightest cluster galaxies, extending as far as z = 0.75; BVR photometry is given for 33 clusters. These data are combined with earlier data of a similar kind in order to investigate several effects. The measured B V and V R colors as a function of redshift are well represented by Whitford's standard-galaxy K corrections, as far as these are defined (to · z = 0.28 in ...

We study here the spontaneous clustering of a submonolayer grains under horizontal circular shaking. The occurs when increasing oscillation amplitude beyond threshold. dense area travels in fashion at driving frequency, which even exceeds speed driving. It turns out that observed is due to formation density waves. analysis phenomenological model shows instability uniform profile arises by and c...

Recently exact numerical results from the evolution equation for parton multiplicities in QCD jets have been obtained. A comparison with various approximate results is presented. A good description is obtained not only of the jet multiplicities measured at LEP-1 but also of the hadron multiplicities for cms energies above 1.6 GeV in eeannihilation. The solution suggests that a final state hadro...
