Sakakibara, Y., On learning from queries and counterexamples in the presence of noise, Information Processing Letters 37 (1991) 279-284. Recently Angluin and Laird have introduced the classification noise process in the Valiant leamability model and proposed an interesting problem to explore the effect of noise in a situation that calls for queries as well as random sampling. In this paper, we ...

Xie, M., Edge linking by using causal neighborhood window, Pattern Recognition Letters 13 (1992) 647-656. A novel edge linking algorithm will be presented in this paper. We shall make use of two concepts: (a) the concept of horizontal edge element and (b) the concept of causal ne,~hborhood window for realizing the edge linking. On the basis of these two concepts, the proposed algorithm will car...

We report the effect of doubly stochastic resonance which appears in nonlinear extended systems if the influence of noise is twofold: A multiplicative noise induces bimodality of the mean field of the coupled network and an independent additive noise governs the dynamic behavior in response to small periodic driving. For optimally selected values of the additive noise intensity stochastic reson...

Dear Sirs, In their letter Chatauret et al. [1] address an interesting issue: in hypothermic machine perfusion for kidney preservation we should have a better understanding of the machine effects versus solution effects. During the discussions concerning the study design the scientific steering committee also discussed which preservation solutions should be used. For more than 40 years, KPS-1 i...

5 l/h) for 16 h (Figure 1), lactic acidosis improved, the haemodynamic situation of the patient stabilized and he was discharged from the ICU. In conclusion, metformin intoxication should be considered in the differential diagnosis for patients with lactic acidosis in the absence of obvious tissue hypoxia [5]. Only early treatment, even in a suspicious case of metformin intoxication, is able to...

We explore a new general-purpose heuristic for finding high-quality solutions to hard discrete optimization problems. The method, called extremal optimization, is inspired by self-organized criticality, a concept introduced to describe emergent complexity in physical systems. Extremal optimization successively updates extremely undesirable variables of a single suboptimal solution, assigning th...

We report on the experimental observation of environment induced decoherence in the quantum deltakicked rotor. Ultracold cesium atoms are subjected to a pulsed standing wave of near resonant light. Spontaneous scattering of photons destroys dynamical localization thereby giving rise to a quantum diffusion, which approaches the classical diffusion with an increasing degree of decoherence. This t...

Bell’s theorem [1] states that one cannot in general reproduce the results of quantum theory with a classical, deterministic local model. Hardy’s argument of “nonlocality without inequalities” [2] is considered “the best version of Bell’s theorem” [3]. Curiously enough, while in the original proof of Bell’s theorem using inequalities the maximum discrepancy with local models occurs for maximall...

A simple technique is explored to determine the temporal photo-response, s, of individual semiconducting SiC and Si nanowires (NWs), with a high time resolution. Laser-assisted field emission (LAFE) from the NWs is first shown to be highly sensitive to continuous laser illumination. Pulsed illumination is then combined with measurements of the total energy distributions to determine s which wer...
