It has long been thought (e.g., Cavanagh & Mather, 1989) that first-order motion-energy extraction via space-time comparator-type models (e.g., the elaborated Reichardt detector) is sufficient to account for human performance in the short-range motion paradigm (Braddick, 1974), including the perception of reverse-phi motion when the luminance polarity of the visual elements is inverted during s...

Engineering ceramics have been widely used in modern industry for their excellent physical and mechanical properties, and they are difficult to machine owing to their high hardness and brittleness. Electrical discharge machining (EDM) is the appropriate process for machining engineering ceramics provided they are electrically conducting. However, the electrical resistivity of the popular engine...

The 15-year development of the European interpretation of the Transition Edge Sensor (TES) microcalorimeter is described within this document. In essence, a TES microcalorimeter is a high-resolution cryogenic photon detector that converts temperature changes induced by incoming photons into changes in electrical resistance. Conceptually, the device consists of an absorber, a detector, heat sink...

In both vertebrates and invertebrates, evidence supports separation of luminance increments and decrements (ON and OFF channels) in early stages of visual processing (Hartline, 1938; Joesch et al., 2010); however, less is known about how these parallel pathways are recombined to encode form and motion. In Drosophila, genetic knockdown of inputs to putative ON and OFF pathways and direct recordi...

Abstract Embedding the ability of sentiment analysis in smart devices is especially challenging because relies on deep neural networks, particular, convolutional networks. The paper presents a novel hardware-friendly detector image polarity, enhanced with saliency detection. approach stems from hardware-oriented design process, which trades off prediction accuracy and computational resources. e...

In this paper, photodetection properties of a Graphene-based device at the third telecommunication window have been reported. The structure of the device is a Graphene-silicon Schottky junction which has been simulated in the form of an infrared photodetector. Graphene has specific electrical and optical properties which makes this material a good candidate for optoelectronic applications. Phot...

Growth of the Avena coleoptile, including elongation and curvature responses, is dependent on the auxin which is produced only by the cells in the extreme apex (4, 12, 13). A polar force is required to direct and control the distribution of this auxin. It frequently has been suggested that the inherent electrical field could function as this force and there is evidence that is consistent with t...
