The visual perception of contours by the brain is selective. When embedded within a noisy background, closed contours are detected faster, and with higher certainty, than open contours. We investigate this phenomenon theoretically with the paradigmatic excitable FitzHughNagumo model, by considering a set of locally coupled oscillators subject to local uncorrelated noise. Noise is needed to over...

Certain parasites can cause severe diseases in shrimp. Among these, protozoa are very important. The objective of our study was to describe the signs, prevalence, and intensity of hemocytosis, a new disease in shrimp, Fenneropenaeus indicus. The experimental design included three groups, one treatment as infected shrimp or group B and 2 controls with non-infected but exposure to White Spot Synd...

Introduction: Hydatid cyst is among parasitic diseases common between man and domestic animals, as well as domestic and non domestic carnivorous animals. This disease causes organ damage and injuries in human, and sometimes leads to death. This study aims at assessment of secondary hydatid cyst growth in laboratory animals and determination of their sensitivity. Materials and Methods: The Pr...

sclerotinia stem rot (white stem rot), an important fungal disease, which is caused by sclerotinia sclerotiorum, is one of the serious diseases of various plants such as canola. use of resistant cultivars is an effective method to control the disease. a greenhouse experiment based on cotyledon inoculation using mycelial suspension of two different isolates of s. sclerotiorum was conducted to ev...
