An analytic drain current model is presented for doped short-channel double-gate MosFETs with a Gaussian-like doping profile in the vertical direction of the channel. The present model is valid in linear and satura- tion regions of device operation. The drain current variation with various device parameters has been demonstrated. The model is made more physical by incorporating the channel length modulation effect. Parameters like transcon- ductance and drain conductance that are important in assessing the analog performance of the device have also been formulated. The model results are validated by numerical simulation results obtained by using the commercially available ATLAs^TM, a two dimensional device simulator from sILVACo.

作者： Gillies A D s Missouri University of science and Technology Rolla Missouri USA

A real-time Diesel Particulate Matter （DPM） monitor has been developed on the base of the successful national In- stitute of occupational Health and safety （nIosH） designed Personal Dust Monitor （PDM） unit. The objectives of a recently completed Australian Coal Association Research Program （ACARP） study was to modify the PDM to measure the submicrometre fraction of the aerosol in a real-time monitoring underground instrument. Mine testing focused on use of the monitor in engineering evaluations of Longwall （LW） moves demonstrated how DPM concentrations from vehicles fluctuate under varying ventilation and operational conditions. The strong influence of mine ventilation systems is reviewed. Correlation between the current sKC DPM measurement system and real-time DPM monitors were conducted and results from eight mines show a correlation between elemental carbon （EC） and the new monitor DPM mass ranging from 0.45 to 0.82 with R2〉0.86 in all but two cases. This differences in suspected to be due to variations from mine to mine in aspects such as mine atmospheric contamination, vehicle fleet variations, fuel type, engine maintenance, engine combustion efficiency, engine behavior or interference from other submicrometre aerosol. Real-time monitoring clearly reflects the movement of individual diesel vehicles and allows pin-pointing of high exposure zones such as those encountered where various vehicles engage in intense work in areas of constrained or difficult ventilation. DPM shift average monitoring approaches do not readily allow successful engineering evaluation exercises to determine acceptability of pollution levels. Identification of high DPM concentration zones allows efficient modification of mine ventilation, operator positioning and other work practices to reduce miners＇ exposures without waiting for laboratory analysis results.

Pandas are endemic to iodine-poor environments and appear to be specialized for a goitrogenic staple *** particular,the importance of thiocyanate in bamboos might possibly have been overlooked in captive breeding *** excreted in urine,thiocyanate first antagonizes absorption of iodine by the thyroid(of parent,fetus and suckling juveniles)and the mammary *** livestock and humans,subclinical deficiency of iodine is known to result in reproductive problems(including retardation of the fetus and suckling infant)even where the mother appears to be unaffected beyond slight hyperplasia of the thyroid and subtle hypothyroidism as reflected by levels of thyroid *** suggest that the possibilities of iodine deficiency or excess should be carefully considered wherever the reproductive rates of pandas are unsatisfactory.

The present paper focuses on study of graphene and strontium titanate（srTio3or sTo） interface. An ambient pressure chemical vapour deposition（AP-CVD） setup is used to grow graphene on sTo（110）substrates in the presence of methane, argon and hydrogen gases at 1000 °C for 4 h. Raman spectroscopy measurements confirm the presence of graphene on sTo substrates due to the existence of typical D and G peaks referring to graphene. These characteristic peaks are missing in the spectrum for bare substrates.X-ray photoelectron spectroscopy（XPs） is carried out for elemental analysis of samples, and study their bonding with sTo substrates. We employed the valence band spectrum to calculate the valence band offset（VBo） and conduction band offset（CBo） at the G-sTo interface. Also, we present an energy band diagram for Bi-layer and ABC（arranging pattern of carbon layers） stacked graphene layers.
