Neuronal response gain enhancement is a classic signature of the allocation of covert visual attention without eye movements. However, microsaccades continuously occur during gaze fixation. Because these tiny eye movements are preceded by motor preparatory signals well before they are triggered, it may be the case that a corollary of such signals may cause enhancement, even without attentional ...

Dairy cattle and buffalo production has undergone a major transformation resulting into a substantial increase in milk production thus helping our country to achieve top position in milk production in the world. Even though various animal breeding and management programmes have contributed to this improvement, there are constraints hampering the growth which require proper attention by initiati...

fuzzy decision tree (fdt) classifiers combine decision trees with approximate reasoning offered by fuzzy representation to deal with language and measurement uncertainties. when a fdt induction algorithm utilizes stopping criteria for early stopping of the tree's growth, threshold values of stopping criteria will control the number of nodes. finding a proper threshold value for a stopping crite...

We describe a two-step ontology engineering methodology by which anatomical knowledge is, first, extracted from comprehensive, though semantically underspecified medical terminologies and then automatically converted into a formally solid description logics format. In the course of this conversion process, particular attention is being paid to the proper representation of partonomies. These con...

Attention increases the contrast gain of V4 neurons, causing them to respond to an attended stimulus as though its contrast had increased. When multiple stimuli appear within a neuron's receptive field (RF), the neuron responds primarily to the attended stimulus. This suggests that cortical cells may be "hard wired" to respond preferentially to the highest-contrast stimulus in their RF, and neu...

Even though a great attention has been given on the cervical cancer diagnosis, it is a tuff task to observe the pap smear slide through microscope. Image Processing and Machine learning techniques helps the pathologist to take proper decision. In this paper, we presented the diagnosis method using cervical cell image which is obtained by Pap smear test. Image segmentation performed by multi-thr...

In the theory of electrocardiography the direction of myocardial fibers has been almost ignored. In order to evaluate whether this is proper or not, directional difference of conduction velocity in the ventricular syncytium was examined by capillary microelectrodes. Conduction velocity in the direction of myocardial fibers was found to be usually several times larger than that vertical to them....
