We aim to understand inherent reasons for lower bounds for QBF proof systems, and revisit and compare two previous approaches in this direction. The first of these relates size lower bounds for strong QBF Frege systems to circuit lower bounds via strategy extraction (Beyersdorff & Pich, LICS’16). Here we show a refined version of strategy extraction and thereby for any QBF proof system obtain a...

The transmission behavior of interconnections in integrated circuits is often determined by their distributed RC effects. In this paper, we present a modeling technique, for incorporation in a layout-to-circuit extraction program, that accurately represents these effects. The method consists of first replacing IC interconnections by a complex RC network and then transforming this complex RC net...

the purpose of this study was to examine serum selenium (se), lipoproteins and testosterone responses to a single session of circuit resistance exercise. fourteen male college students volunteered in the present study. blood samples were taken at 30minutes before, immediately after 25 and 60minutes of single session of circuit resistance exercise (10 exercise, 20s for each exercise, and at 60%1...

On-chip inductance extraction and analysis is becoming increasing critical. Inductance extraction can be difficult, cumbersome and impractical on large designs as inductance depends on the current return path — which is typically unknown prior to extracting and simulating the circuit model. In this paper, we propose a new circuit element, K, to model inductance effects, at the same time being e...

From a background of RC interconnect models in layout-to-circuit extraction, this paper compares two realizable model reduction methodologies based on generalized Y∆ transformation. The first method represents admittances through a rational function in the s-domain, where the numerator and denominator polynomials are truncated at a user-defined order. During the Y∆ transformation, common factor...

An original parameters extraction strategy has been developed using a physical and scalable 2π equivalent on-chip spiral inductors RLC circuit model. This strategy based on optimization only, was used to model spice model parameters as a function of geometrical inductor parameters. The data used in this paper were obtained by using a 3D electromagnetic Field Solver combined with a Design of Exp...

OBJECTIVE This synthetic review was performed to demonstrate the utility of frontal-subcortical circuits in the explanation of a wide range of human behavioral disorders. DATA SOURCES Reports of patients with degenerative disorders or focal lesions involving frontal lobe or linked subcortical structures were chosen from the English literature. Individual case reports and group investigations ...

We demonstrate an optical clock recovery circuit that extracts the line rate component on a per packet basis from short data packets at 40Gb/s. The circuit comprises a Fabry-Perot filter followed by a novel power limiting configuration, which in turn consists of a 5m highly nonlinear bismuth oxide fiber in cascade with an optical bandpass filter. Both experimental and simulation-based results a...

This paper proposes a biologically-inspired feature extraction method, which consists of coarse region segmentation by a resistive-fuse network and feature extraction by Gabor wavelet transforms. Their pixel-parallel VLSI implementation based on the pulse modulation circuit architecture is described, and measurement results of Gabor filter operation by a test LSI chip with 1-D 20-pixels are pre...
