The temporal dynamics of visual crowding and segmentation

Michael Herzog, Gregory Francis, Mauro Manassi

Perception of a target strongly deteriorates when flanking elements are presented (crowding). Classically, crowding is explained by pooling mechanisms where target and flanker features are combined, e.g., when neurons in higher visual areas with larger rec ...

JET ILA full array and polychromatic operation

The JET ILA is an Ion Cyclotron Resonance Heating (ICRH) antenna composed of four resonant double loops (RDLs) arranged in a 2 toroidal by 2 poloidal compact array. It has been operated in a range of frequencies from 29 to 51 MHz, but mostly on half array. ...

Synthesis of uniform amplitude focused beam arrays

Juan Ramon Mosig, Anja Skrivervik, Benjamin Fuchs

An iterative algorithm to synthesize uniform amplitude focused beam arrays is presented. While the number of array elements and the excitations are fixed and known, the locations of the elements are optimized to radiate a narrow beam low sidelobe pattern. ...

Enhancing the Performances of H-plane SIW Horn Antennas

Juan Ramon Mosig, Marc Esquius Morote, Benjamin Fuchs

The performances of SIW horns antennas diminish significantly when the substrate thickness is much smaller than the free space wavelength lambda(0). Specifically, the mismatch between the antenna aperture and the air yields to unwanted back radiation and p ...

Synthesis of uniform amplitude focused beam arrays

Juan Ramon Mosig, Anja Skrivervik, Benjamin Fuchs

An iterative procedure for the synthesis of uniform amplitude focused beam arrays is presented. Specifically, the goal is to optimize the locations of a fixed number of array elements with known excitations in order to synthesize narrow-beam low-sidelobe p ...

Optimal polarization synthesis of arbitrary arrays with focused power pattern

Benjamin Fuchs

The joint synthesis of the spatial power pattern and polarization of arbitrary arrays is addressed. Specifically, the proposed approach gives the solution to a frequently encountered problem, namely the array design (i.e., the determination of the radiatin ...

Application of Supramolecular Nanostamping to the Replication of DNA Nanoarrays

Francesco Stellacci, Ying Hu

The rapid development of molecular biology is creating a pressing need for arrays of biomolecules that are able to detect smaller and smaller volumes of analytes. This goal can be achieved by shrinking the average size and spacing of the arrays constituent ...

Grouping of contextual elements that affect vernier thresholds

Michael Herzog

To reveal the mechanisms of spatial interference in the fovea, we examined the capacity of a variety of lateral flanking configurations to interfere with alignment thresholds of a vertical vernier. A single line on each side of the vernier, at the optimal ...

Fast Functional Lists, Hash-Lists, Deques and Variable Length Arrays

Since its inception Functional Programming, J. McCarthy, has almost universally used the Linked List as the underpinning data structure. This paper introduces a new data structure, the VList, that is compact, thread safe and significantly faster to use tha ...
