it is important for people to improve cognitive and motor performance. the purpouse of this study was to investigate the effect of running on treadmill in spatial memory and learning and motor performance. 24 albino-wistar healthy male rats were randomly divided into control and activity groups. activity group ran 7 days on treadmill (speed 22m/min 30 minutes a day). after the end of activity p...

We tested between two coding mechanisms that the brain may use to retain distance information about a target for a reaching movement across vergence eye movements. If the brain was to encode a retinal disparity representation (retinal model), i.e., target depth relative to the plane of fixation, each vergence eye movement would require an active update of this representation to preserve depth c...

MicroRNAs (miRNAs) have the potential to regulate the expression of thousands of genes, but the mechanisms that determine whether a gene is targeted or not are poorly understood. We studied the genomic distribution of distances between pairs of identical miRNA seeds and found a propensity for moderate distances greater than about 13 nt between seed starts. Experimental data show that optimal do...

Valuable resources often exist at distant points from a firm’s current locations, so that strategic decisions such as growth have a spatial dimension in which firms seek information and choose between geographically distributed alternatives. Studies show that geographic proximity facilitates the flow of resources, but there is limited understanding of factors that exacerbate or ease the impact ...

the genetic variation and diversity among fifty-eight polyvoltine silkworm genotypes was estimated by using ten economic traits. the results revealed that the single shell weight showed higher genetic variation such as pcv% (17.20%), gcv% (12.93%), and heritability (56.5%) followed by single cocoon weight, shell ratio and matured larval weight. the d2 (mahalonobis? distance) statistics revealed...

BACKGROUND Patients with intermittent exotropia may have an increase in their angle of strabismus in the distance when the angle is measured either after 1 hour of monocular occlusion or while the patients fixate on a distant target outdoors. The hypothesis that surgery should be performed for this larger deviation has been suggested but not tested. OBJECTIVES To test the hypothesis that surg...

How does the geographic distance between potential acquiring and target firms affect acquisition strategy? Although popular discussions suggest that distance may be critically important to strategy, formal research on acquisition-based growth has paid little attention to spatial factors. This study examines how the distance between acquiring and target firms influences target selection, explori...
