To avoid collisions, flies steer away from expanding visual scenes generated during straight flight: so how do they fly forward when no collision is imminent? A new study shows that wind compensates for this aversion, allowing flies to forge ahead.

In this paper a closed form solution of a fractional integro-differential equation of Volterra type involving Mittag-Leffler function has been obtained using straight forward technique of Sumudu transform. Some particular cases have also been considered.

We asked whether podokinetic adaptation to walking on a circular treadmill transfers to different forms of locomotion. Subjects were blindfolded and asked to walk straight across the floor, in the forward and backward directions, following podokinetic (PK) stimulation that consisted of 30 min of forward walking-in-place on the perimeter of a disk rotating in the clockwise direction. During both...

1. The dorsal part of the medial superior temporal area (MST) is characterized by clusters of three types of visually responsive cells: Direction cells, which respond to a straight frontoparallel movement in a particular direction; Expansion/contraction cells, which selectively respond to either an expansion or contraction; and Rotation cells, which selectively respond to either a clockwise or ...

How can high product concentrations be continuously provided, while dealing with substrate toxicity? Which method leads to a straight forward isolation? The example of model based process intensification shows how.

the most widely used machine for precision sowing of cucumber and sorghum seeds is vacuum type. the performance and distribution accuracy of the vacuum type metering unit is of great importance. therefore, the experiments at three pressures of 25, 35, 45 mbar and two level of forward speed 3 to 4.5 km/h and 6 to 8.5 km/h were conducted and multiple planting, feeding quality and miss planting we...

For iterative solvers, besides convergence proofs that may state qualitative results for some classes of problems, straight-forward methods to compute (bounds for) convergence rates are of particular interest. A widelyused straight-forward method to analyze the convergence of numerical methods for solving discretized systems of partial differential equations (PDEs) is local Fourier analysis (or...
