the direct voice of the poet hides from the beginning of the poem to its end, or the name that the poet speaks through which about himself detached from his or her substantiality, or he is just a historic character..., behind that the poet hides himself to interpret the situation that he wants or to criticize the vices of modern age through it, or to speak of it for some of his concerns and wor...

localizing the optic disc (od) in retinal fundus images is of critical importance, since it is very similar to hard exudates (found in pathology) in color and brightness. because of the importance of od localization in clinical applications, many techniques have been developed. in this paper, we present the results obtained from two methods, correlation and least square, to approximate the opti...

Maintained exposure to a specific stimulus property-such as size, color, or motion-induces perceptual adaptation aftereffects, usually in the opposite direction to that of the adaptor. Here we studied how adaptation to size affects perceived position and visually guided action (saccadic eye movements) to that position. Subjects saccaded to the border of a diamond-shaped object after adaptation ...

Periocular is one of the promising biometric traits for human recognition. It encompasses a surrounding area eyes that includes eyebrows, eyelids, eyelashes, eye-folds, eye shape, and skin texture. Its relevance more emphasize during COVID-19 pandemic due to masked faces. So, this article presents detailed review periocular biometrics understand its current state. The paper first discusses vari...

abstract this study aims to examine the use of religion heritage and application of the prophet job’s character mask. one of the important masks that have been used by contemporary poets is the prophet’s masks, especially the job of which the story exists in the quran. this character is a symbol of patience. darvish and sayyab are the most important poets who used the mask of this character.  e...

The response of a cell in the primary visual cortex to an optimally oriented grating is suppressed by a superimposed orthogonal grating. This cross-orientation suppression (COS) is exhibited when the orthogonal and optimal stimuli are presented to the same eye (monoptically) or to different eyes (dichoptically). A recent study suggested that monoptic COS arises from subcortical processes; howev...

Ground squirrels were monocularly exposed to either steady- or flashing-diffuse light for 45 min following an injection of 14C 2-deoxyglucose (2-DG). Autoradiographic analysis indicated greater metabolic activity in the lateral geniculate nucleus, visual cortex and superior colliculus (SC) of the hemisphere lying contralateral to and receiving input from the diffusely stimulated eye (covered by...

A distractor presented nearby the target of a goal-directed short latency saccade leads to spatial averaging, that is, the saccade lands between the target and the distractor. This so-called global effect is a characteristic feature of the spatial processing underlying the programming of saccadic eye movements. To determine whether this effect of near distractors on saccade metrics is also refl...

We evaluated the effectiveness of a multifaceted general anesthesia protocol designed to minimize postoperative vomiting after pediatric eye surgery. A convenience sample of 150 consecutive children, aged 2 weeks to 18 years, who received general anesthesia for pediatric ophthalmic surgery was studied. General anesthesia was administered with induction by mask for 82.7% of the children and intr...
