This paper discusses issues in the design of analog-todigital converters (ADCs) in nanoscale CMOS and introduces some experimental designs incorporating techniques to solve these issues. Technology scaling increases the maximum conversion rate, but it decreases the gain and the SNR. To maintain a high SNR level despite the lowvoltage operation, the power consumption needs to be increased. Becau...

This paper proposes a new approach for high-resolution airborne SAR data processing, which uses a modified chirp scaling algorithm to accommodate the correction of motion errors, as well as the variations of the Doppler centroid in range and azimuth. By introducing a cubic phase term in the chirp scaling phase, data acquired with a squint angle up to 30" can be processed with no degradation of ...

By using the maximum entropy principle with Tsallis entropy we obtain a fragment size distribution function which undergoes a transition to scaling. This distribution function reduces to those obtained by other authors using Shannon entropy. The treatment is easily generalisable to any process of fractioning with suitable constraints.

Using a microscopic numerical approach suitable to describe disordered antiferromagnets, with application to F e x Zn 1−x F 2 , it is shown that the characteristics of the spin glass phase found for x = 0.25 is much in agreement with the scenario predicted by the scaling theory of the droplet model .

introduction: the aim of this study was to evaluate the influence of different levels of external irrigation during irradiation with an erbium, chromium: yttrium-scandium-gallium-garnet (er,cr:ysgg) laser on the roughness and wear of dental tissue during scaling procedures. methods: twenty-five uniradicular bovine teeth had the proximal surfaces planed and divided into 3 regions: upper, middle ...

We prove rigorously that the one-particle density matrix of interacting Bose systems with a short-scale repulsive pair interaction converges to the solution of the Gross-Pitaevskii equation in suitable scaling limits. The result is extended to k-particle density matrices for all positive integer k. AMS Classification Number (2000): 35Q55, 81Q15, 81T18, 81V70. Running title: Derivation of Gross-...

It is shown that, with an appropriate scaling, the energy of low-lying excitations of the (1; 1; : : : ; 1) interface in the d-dimensional quantum Heisenberg model are given by the spectrum of the d ? 1-dimensional Lapla-cian on an suitable domain. of this article in its entirety, by any means, is permitted for non-commercial purposes.

The suitable interpolation between classical percolation and a special variant of explosive percolation enables the explicit realization of a tricritical percolation point. With high-precision simulations of the order parameter and the second moment of the cluster size distribution a fully consistent tricritical scaling scenario emerges yielding the tricritical crossover exponent 1/φ(t)=1.8 ± 0.1.
