During oblique saccades, the durations of the horizontal and vertical components are stretched until they are approximately equal. Models of the saccadic system have been proposed that provide a mechanism for that stretching. However, they fail to simulate the pattern of activity recorded from premotor medium lead burst neurons (MLBNs) in the brain stem. A new model of the saccadic system is pr...

Many bacterial and archaeal lineages have a history of extensive and ongoing horizontal gene transfer and loss, as evidenced by the large differences in genome content even among otherwise closely related isolates. How ecologically cohesive populations might evolve and be maintained under such conditions of rapid gene turnover has remained controversial. Here we synthesize recent literature dem...

We investigated the effect of visually mediated eye movements made before velocity-step horizontal head rotations in eleven normal human subjects. When subjects viewed a stationary target before and during head rotation, gaze velocity was initially perturbed by approximately 20% of head velocity; gaze velocity subsequently declined to zero within approximately 300 ms of the stimulus onset. We u...

There is an error in the Materials and Methods section of this paper. Section 6, “Identification of Horizontal Gene Transfer (HGT) -derived Genes in Foc1 and Foc4,” should not appear. In addition, Lijia Guo is incorrectly designated as the corresponding author. The correct corresponding authors are: Junsheng Huang ([email protected]), Ming Peng ([email protected]), and Xiaodong Fang (fangxd@g...

Genetic control programs for scrapie in sheep build on solid knowledge of how susceptibility to scrapie is modulated by the prion protein genotype at the level of an individual sheep. In order to satisfactorily analyze the effectivity of control programs at the population level, insight is needed at the flock level, i.e., how the grouping of sheep in flocks affects the population-level transmis...

This work presents a methodology for horizontal soil stratification and device 3D mapping using the discretization of Wenner’s method. The starts from application lateral profiling method in conjunction with to find experimental resistivity curve. Sunde’s algorithm is used construct theoretical By utilizing these curves, it possible apply optimization process parameters: electrical conductivity...

varieties of st. john’s wort (hypericum perforatum l.) native to iran possess the largest percentage of hypercin in their leaves and flowers. isotherm curves show the relationship between the relative humidity and moisture content of the plant at a constant temperature. it is essential to understand the isotherms curves for successful storage and drying of the plant. this study used adsorption ...

Flexible assembly joint is the key problem to coordinate deformation of hybrid structure. This study aims investigate mechanical behaviors and its main influence parameters flexible timber column reinforced concrete beam. Finite element models were established analyzed. The discussed including horizontal bearing capacity, stiffness load-displacement hysteretic loops. vertical load rubber perfor...
