Design of new logic architectures utilizing optimized suspended-gate single-electron transistors
No full textThe operation and performances of the suspended-gate single-electron transistor (SET) are investigated through simulation. The movable gate is 3-D optimized, so that low actuation voltage (0.4 V), fast switching (1 ns), and ultralow pull-in energy (0.015 fJ) are simulated. A two-state capacitor model based on the 3-D results is then embedded with a SET analytical model in a SPICE environment to investigate the operation of the device. Through the control of the Coulomb oscillation characteristics, the position of the movable gate enables a background charge insensitive coding of the information. New circuit architectures with applications in cellular nonlinear network and pattern matching are also proposed and simulated

Effects of the radial inflow of gas and galactic fountains on the chemical evolution of M 31
No full textContext. Galactic fountains and radial gas flows are very important ingredients for modeling the chemical evolution of galactic disks.
Aims: Our aim here is to study the effects of galactic fountains and radial gas flows on the chemical evolution of the disk of Andromeda (M 31) galaxy.
Methods: We adopt a ballistic method to study the effects of galactic fountains on the chemical enrichment of the M 31 disk by analyzing the landing coordinate of the fountains and the time delay in the pollution of the interstellar gas. To understand the consequences of radial flows, we adopt a very detailed chemical evolution model. Our aim is to study the formation of abundance gradients along the M 31 disk and also compare our results with the Milky Way.
Results: We find that the landing coordinate for the fountains in M 31 is no more than 1 kpc from the starting point, thus producing a negligible effect on the chemical evolution of the disk. We find that the delay time in the enrichment process due to fountains is no longer than 100 Myr, and this timescale also produces insignificant effects on the results. Then, we compute the chemical evolution of the M 31 disk with radial gas flows produced by the infall of extragalactic material and fountains. We find that a moderate inside-out formation of the disk, coupled with radial flows of variable speed, can reproduce the observed gradient very well. We also discuss the effects of other parameters, such as a threshold in the gas density for star formation and efficiency of star formation varying with the galactic radius.
Conclusions: We conclude that galactic fountains do not affect the chemical evolution of the M 31 disk. Including radial gas flows with an inside-out formation of the disk produces a very good agreement with observations. On the other hand, if radial flows are not considered, one should assume a threshold in the star formation and variable star formation efficiency, besides the inside-out formation to reproduce the data. We conclude that the most important physical processes in creating disk gradients are the inside-out formation and the radial gas flows. More data on abundance gradients both locally and at high redshift are necessary to confirm this conclusion
Hyperfunctions with real analytic parameters and continuation of solutions of systems of partial differential equations
No full textAbstractThe purpose of this paper is to introduce a "sheaf" of hyperfunctions with Cω-parameters at the boundary, to study its behavior under the trace morphism, and to state some criteria on extension of solutions of systems of P.D.E. across singular sets of codimension ≥ 1. Let M be a Cω-manifold, X a complexification of M, Ω an open set with Cω-boundary N = ∂Ω, Y a complexilication of N, V a closed conic regular involutive submanifold of T*MX\ T*YX transversal to N × MT*MX with regular involutjve intersection. Let M be a DX-module for which Y is non-characteristic. We introduce a complex BaM | X = Ba, VM | X whose 0th cohomology consists of those hyperfunctions on M which depend real analytically on the variables transversal to the leaves of V. We also introduce a new complex BaΩ | X = Ba, VΩ | X whose main feature is that traces on N of H0(Ba, VΩ | X)-so1utions of M belong to H0(Ba, V′N | Y)). (Here V′ = ρω−1(V) with T*Y ← ρY × XT*X → ωT*X.) We are then able to state in Section 3 several principles on continuation of hyperfunction solutions with Cω-parameters (resp. real analytic solutions) to systems M across a subset S contained in a non-characteristic boundary N. The method (inspired by [Kan2]) consists in proving that under some hypotheses on non-microcharacteristicity of N, ΓΩ(H0(BaM | X))-solution f of M belongs automatically to H0(BaΩ | X) (Ω = Ω± denoting the components of M \ N), and therefore their traces γ ± (f) on N satisfy SSγ ± (f) ∩ V′ = Ø. The extendability of f across S is then an immediate consequence of the propagation 0 for γ+ (f) − γ−(f) from N \ S up to N
