As the size of a transistor continuously scales down, single electron effects become important [1 – 3]. Previously, we have studied charge transport in single-electron quantum dot transistors which have a channel consisting of a silicon dot separated from the source and the drain by two constrictions [4], and in single-electron MOS memories that have a polysilicon dot floating gate stacked on a...

definitive hosts of the echinococcus granulosus (e. granulosus ) parasite are carnivores such as dogs,wolves and foxes. detection of this parasite through faecal examination is not possible. in this study, dotblotting test for e. granulosus -specific coproantigens has been evaluated in dog. three 2–3-month-old puppies were treated with piperazine and then faecal samples were collected as pre-in...

Novel quantum-dot-tagged photonic crystal beads were fabricated for multiplex detection of tumor markers via self-assembly of quantum dot-embedded polystyrene nanospheres into photonic crystal beads through a microfluidic device.

A noninteracting quantum-dot arrays side coupled to a quantum wire is studied. Transport through the quantum wire is investigated by using a noninteracting Anderson tunneling Hamiltonian. The conductance at zero temperature develops an oscillating band with resonances and antiresonances due to constructive and destructive interference in the ballistic channel, respectively. Moreover, we have fo...

We review the phenomena having an impact on the interaction between light, paper and color halftones. They comprise surface reflections and refractions at the air-paper interface, propagation of light within the paper, internal reflections at the paper-air interface, as well as ink spreading and trapping. We introduce basic notions from radiometry and optics, such as the definitions of radiant ...

background: neospora caninum is a protozoan parasite from phylum apicomplexa and an important agent causing abortion in cattle which produce notable economic loss all around the world. methods: dot-elisa was set up performing checker board procedure and then 178 sera of cattle examined with commercial indirect elisa and direct agglutination test (dat) were also evaluated by dot-elisa afterwards...

The out-of-equilibrium transport properties of a double quantum dot system in the Kondo regime are studied theoretically by means of a two-impurity Anderson Hamiltonian with interimpurity hopping. The Hamiltonian is solved by means of a nonequilibrium generalization of the slave-boson mean-field theory. It is demonstrated that measurements of the differential conductance dI/dV, for appropriate ...

We have measured the low-temperature transport properties of an open quantum dot formed in a clean one-dimensional channel. For the first time, at zero magnetic field, continuous and periodic oscillations superimposed upon ballistic conductance steps are observed when the conductance through the dot G exceeds 2e 2 /h. We ascribe the observed conductance oscillations to evidence for Coulomb char...

This study evaluated the effects of a number of chemicals on the physical and mechanical properties and fire, decay, andtermite resistance of oriented strandboard (OSB) panels. Disodium octaborate tetrahydrate (DOT), boric acid (BA), melamine phosphate (MP), and a BA/DOT mixture were sprayed onto the furnish at varying concentrations. Thepanels were tested for thickness swell, water absorption,...
