The electrostatic interaction between two capacitively coupled, series-connected metal double dots is studied at low temperatures. Experiment shows that when the Coulomb blockade is lifted, by applying appropriate gate biases, in both double dots simultaneously, the conductance through each double dot becomes significantly lower than when only one double dot is conducting a current. The conduct...
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...
background : toxoplasmosis is a worldwide endemic disease. in congenitally infected infants and aids patients, toxoplasmosis causes high rates of morbidity and mortality. in these cases antibody detection is difficult; so detection of parasite or its components could be useful tool for early detection and following treatment of the infection. methods : sixty-three balb/c mice were injected intr...
We study stabilization of moduli in the type–IIB superstring theory on the six-dimensional toroidal orientifold T6/Ω · (−1)L · Z2. We consider background space-filling D9-branes wrapped on the orientifold along with non-Abelian fluxes on its world-volume and demonstrate with two examples that this can stabilize all the complex structure moduli and some of the Kähler moduli. kumar(at) iopb (dot)...
Magnetic fields grow quickly even at early cosmological times, suggesting the action of a small-scale dynamo (SSD) in interstellar medium galaxies. Many studies have focused on idealized turbulent driving SSD. Here we simulate more realistic supernova-driven turbulence to determine whether it can drive an field growth occurring our models appears inconsistent with simple tangling magnetic field...
Directly observation therapy (DOT) has been accepted as the basic method for controlling tuberculosis. The present study aimed to determine the risk factors that affect sputum culture conversion rate in the DOT managed and non-DOT managed hospitalized patients. The study was included 50 cases with positive sputum cultures between the dates April 2001-April 2002 when DOT was not applied and 60 c...
In this paper, the nonlinear rate equations governing a quantum dot laser isused to simulate the transient as well as the steady-state behaviors of the laser.Computation results show that the rate equations are capable of simulating true behaviorof a quantum dot laser. Then, the pump rates of the rate equations (which show indirectelectrical pumping of the quantum dots through a wetting layer) ...
Printer manufacturers design print heads and halftone patterns to result in specific types of image characteristics. Many image quality artifacts are a result of differences in actual dot placement from intended dot placement. Quantifying dot placement variations can be a complex endeavor requiring image capture at high magnification for adequate sampling. Large dot fields are imaged in pieces,...
