Most adults and children in cultures where reading text progresses from left to right also count objects from the left to the right side of space. The reverse is found in cultures with a right-to-left reading direction. The current set of experiments investigated whether vertical counting in the horizontal plane is also influenced by reading direction. Participants were either from a left-to-ri...

We have developed a novel fabrication ap proach to generate massively-parallel, highaspect-ratio vertical nanofluidic channels with smooth, vertical sidewalls and precise control of uniform gap sizes (lateral trench width) down to 50 nm (Figure 1) [1]. The aspect ratio can be as high as 400 and the channel depths are more than 20 μm. This technique enables us to fabricate a large area of solid ...

We demonstrate a 3D conductive coupling mechanism for the efficient generation of prominent and robust Fano resonances in 3D metamaterials (MMs) formed by integrating vertical U-shape split-ring resonators (SRRs) or vertical rectangular plates along a planar metallic hole array with extraordinary optical transmission (EOT). In such a configuration, intensified vertical E-field is induced along ...

The dynamical behavior of a thin flexible array array motion, becomes more critical. Typical of the more towed through the water is described by the Paidoussis equation. sophisticated towed array processing techniques are adaptive By discretizing this equation in space and time a finite dimenbeamforming [31, adaptive cancellation of tow vessel noise sional state space representation is obtained...

The need for clean groundwater resources to have sustainable development in a country is undoubted. Due to the importance and high quality of karstic waters in supplying water in Iran especially in Shahrood city, it is attempted in this research work to recognize and explore karstic waters in southwest of Tepal area, Shahrood. For this purpose, integration of the results obtained from the metho...

It has already been established that by cross-correlating ambient noise time series received on the upward and downward steered beams of a drifting vertical array one can obtain a subbottom layer profile. Strictly, the time differential of the cross correlation is the impulse response of the seabed. Here it is shown theoretically and by simulation that completely uncorrelated surface noise resu...

Friction forces can be used to move objects along a planar horizontal surface by vibrating the surface with two degrees of freedom. The method presented here uses a combination of horizontal and vertical oscillations to produce a non-zero resulting friction force. Using this principle, objects can be moved along any horizontal direction with variable speed. If many small surface elements are pl...

We construct multi-center solutions for charged, dilatonic, non-extremal black holes in D = 4. When an infinite array of such non-extremal black holes are aligned periodically along an axis, the configuration becomes independent of this coordinate, which can therefore be used for Kaluza-Klein compactification. This generalises the vertical dimensional reduction procedure to include non-extremal...

A passive acoustic method is presented for tracking sperm whale dive profiles, using two or three hydrophones deployed as either a vertical or large-aperture towed array. The relative arrival times between the direct and surface-reflected acoustic paths are used to obtain the ranges and depths of animals with respect to the array, provided that the hydrophone depths are independently measured. ...

The Silicon Tracking System of the CBM Experiment consists of eight tracking layers of silicon detectors. Each layer is an array of vertical modules containing 300 μm thick double-sided silicon strip sensors. The strip pitch is 60 μm on both sides. The sensors are segmented into 1024 strips per side. On either side the strips are tilted by +7.5◦ or -7.5◦ with respect to the vertical edge, creat...
