FitzHugh-Nagumo (FHN) model is a famous Reaction-Diffusion System which first introduced for the conduction of electrical impulses along a nerve fiber. This model is also considered as an abstract model for pattern formation. Here, we have used the Cellular Automata method to simulate the pattern formation of the FHN model. It is shown that the pattern of this model is very similar to those...

We investigate the effects of reflecting connectivity in a network composed FitzHugh–Nagumo (FHN) elements linked ring topology. Reflecting is inspired by linking between opposite hemispheres mammalian brain. To study synchronization phenomena and coexistence synchronous asynchronous domains (chimera states) under influence this connectivity, we use two versions FHN model: Version I where membr...

In order to assess the relevance of canine splenic pathology, to emphasise the differential diagnostic criteria among splenic haematoma, haemangioma and haemangiosarcoma, and to focus on the recently proposed classification of canine splenic fibrohistiocytic nodules (FHN), a retrospective study was carried out on HE-stained sections from formalin-fixed and paraffin-embedded samples from 109 spl...

BACKGROUND Youths with family history (FH) of alcoholism are at greater risk of developing alcohol use disorder (AUD); heightened impulsive behavior may underlie such increased vulnerability. Here, we studied waiting impulsivity (previously suggested to predispose to alcohol drinking) in young moderate-to-heavy social drinkers (18 to 33 years old) characterized as family history positive (FHP) ...

BACKGROUND A single subanesthetic infusion of the N-methyl-D-aspartate (NMDA) receptor antagonist ketamine has rapid and potent antidepressant properties in treatment-resistant major depressive disorder (TRD). As a family history of an alcohol use disorder is a positive predictor of ketamine's antidepressant response and the strength of the association increases over time, we hypothesized that ...

The Flexible Hypercube FHN is an important variant of the Hypercube Hn and possesses many desirable properties for interconnection networks. This paper proposes a novel algorithm of fault-tolerant method for mapping a mesh network in a Flexible Hypercube. The main results obtained (1) a searching path of a FHN is including approximate to (n+1) nodes, where n= 2 log N ⎢ ⎥ ⎣ ⎦ . Therefore, there ...

High utility itemset (HUI) mining is a popular data mining task. It consists of discovering sets of items generating high profit in a transaction database. Several efficient algorithms have been proposed for this task. But few can handle items with negative unit profits despite that such items occurs in many real-life transaction databases. Mining HUIs in a database where items have positive an...

The interplay of time-delayed feedback and temporally correlated coloured noise in a single and two coupled excitable systems is studied in the framework of the FitzHugh-Nagumo (FHN) model. By using coloured noise instead of white noise, the noise correlation time is introduced as an additional time scale. We show that in a single FHN system the major time scale of oscillations is strongly infl...

An excitable medium has two key properties: a sufficiently large stimulus provokes an even bigger response (excitability), and immediately following a stimulus the medium cannot be excited (refractoriness). A large class of biological systems from cardiac tissue to slime mold are examples of excitable media. FitzHugh Nagumo (FHN) is the canonical model of excitable media. Its two variables are ...
