Recently, Starns et al. (2008) collected source judgments for old items, which participants had claimed to be new, and found residual source discriminability depending on the old-new response bias. The finding was interpreted as evidence in favor of the multivariate signal-detection model but against the high-threshold model of source memory. According to the latter, “new” responses only follow...

We study a distributed adversarial model of computation in which the faults are non-stationary and can move through the network (like viruses) as well as non-threshold (there is no specific bound on the number of corrupted players at any given time). We show how to construct multiparty protocols that are perfectly secure against such generalized mobile adversaries. The key element in our soluti...

Autonomous threshold element circuit networks are used to investigate the structure of neural networks. With these circuits, as the transition functions are threshold functions, it is necessary to consider the existence of sequences of state configurations that cannot be transitioned. In this study, we focus on all logical functions of four or fewer variables, and we discuss the periodic sequen...

We evaluate the threshold matrix–element for the reaction pp → ppπ0 in a fully relativistic Feynman diagrammatic approach. We employ a simple effective range approximation to take care of the S–wave pp final–state interaction. The experimental value for the threshold amplitude A = (2.7 − i 0.3) fm4 can be reproduced by contributions from tree level chiral (long–range) pion exchange and short–ra...

Optical feedback from an external cavity containing an element of dispersive loss was used to reduce the amplitude noise of a semiconductor laser. At feedback levels of Pfb/P0t 1O_2, a maximum amplitude noise reduction of 16 dB was measured close to threshold but the potiential for reduction was reduced considerably at higher injection currents as the laser noise approached the shot noise limit...

In this work we present both experimental and theoretical thermal analysis of an electrically pumped hybrid silicon evanescent laser. Measurements of an 850 mum long Fabry-Perot structure show an overall characteristic temperature of 51 oC, an above threshold characteristic temperature of 100 oC, and a thermal impedance of 41.8 oC/W. Finite element analysis of the laser structure predicts a the...

This paper presents the rationale for νMOS-based realizations of digital circuits when logic design techniques based on threshold logic gates (TGs) are used. Some practical problems in the νMOS implementation of threshold gates have been identified and solved. The feasibility and versatility of the proposed technique as well as its potential as a low-cost design technique for CMOS technologies ...

This paper explores the use of threshold gates for the design of complex logic functions. The usefulness of the approximation is determined by the efficient CMOS realization proposed for the threshold gates. New implementations are presented for two different circuits, the Muller C-element and the Losq’s voter for self-purging redundancy, which illustrate the feasibility and versatility of the ...

Attention is called to previous research on realization of an arbitrary switching function by a network of threshold gates (or threshold elements) and modulo 2 gates (or parity elements), establishment of greatest lower bounds on the number of gates needed, artifices that lead to further network reduction in special cases, and systematic minimization of the number of module 2 gates required. Al...
