The response of a noisy nonlinear system to deterministic input signals can be enhanced by cooperative phenomena. We show that when one presents two square waves as input to a two-state system, the response of the system can produce a logical output (NOR/OR) with a probability controlled by the noise intensity. As one increases the noise (for fixed threshold or nonlinearity), the probability of the output reflecting a NOR/OR operation increases to unity and then decreases. Changing the… Expand

Logical stochastic resonance
In a recent publication it was shown that, when one drives a two-state system with two square waves as input, the response of the system mirrors a logical output (NOR/OR). The probability of… Expand
Realization of reliable and flexible logic gates using noisy nonlinear circuits
It was shown recently [Murali et al., Phys. Rev. Lett. 102, 104101 (2009)] that when one presents two square waves as input to a two-state system, the response of the system can produce a logical… Expand
Construction of logic gates exploiting resonance phenomena in nonlinear systems
TLDR
The conventional LSR paradigm is extended to implement higher-level logic architecture or typical digital electronic structures via carefully crafted coupling schemes and to realize morphable logic gates through the Logical Coherence Resonance in excitable systems under the influence of noise.

TLDR
It is demonstrated that the array enhanced logical stochastic resonance has a saturating effect at larger array size, and the small or medium array size is good enough for one to obtain reliable logic operation. Expand

TLDR
It is shown how the input-output correspondence can be controlled by an external exponentially correlated dichotomous noise optimizing the logical response which exhibits a maximum at an intermediate value of correlation time. Expand
The Availability of Logical Operation Induced by Dichotomous Noise for a Nonlinear Bistable System
Instead of a continuous system driven by Gaussian white noise, logical stochastic resonance will be investigated in a nonlinear bistable system with two thresholds driven by dichotomous noise, which… Expand
Coupling induced logical stochastic resonance
Abstract In this work we will demonstrate the following result: when we have two coupled bistable sub-systems, each driven separately by an external logic input signal, the coupled system yields… Expand
Logic signals driven stochastic resonance in bistable dynamics subjected to 1/f noise floor
Abstract. In the presence of 1/fβ noise, we investigate the logical stochastic resonance (LSR) in an asymmetric bistable model driven by various cycling combinations of two logic inputs. The… Expand
Realizing reliable logical stochastic resonance under colored noise by adding periodic force
Abstract Some noisy nonlinear systems could be exploited to operate as reliable logic gate in an optimal window of noise intensity, which is termed as logical stochastic resonance (LSR). Recent… Expand
Enhanced logical stochastic resonance under periodic forcing
TLDR
It is established that in scenarios where noise level is below the minimum threshold required for logical stochastic resonance (or stochastically resonance in general), a periodic forcing can be added to obtain the desired effects. Expand

I am writing with a simple plea to balance the voluminous articles about treatment in your journal with a modicum of information about nature and caring effects to rekindle the perception of physicians as healers, not only treaters, who relish the gifts of nature, and foster the humanistic aspect of medicine that has thrived for millennia.
