An important probe of dark energy is the integrated Sachs-Wolfe effect, where cosmic microwave background anisotropies are generated at late times once the dark energy becomes important dynamically. This contribution briefly describes the effect and summarises the present observational evidence for it. A potential survey by the Square Kilometre Array (SKA) covering a large fraction of the sky c...

ELI is a succinct interactive programming language system organized around a few simple principles. Its main data structures include arrays, lists, dictionaries and tables. In addition, it has an integrated database management component which is capable of processing a basic set of SQL statements. ELI, with a compiler, covering the array portion of the language, is also an excellent tool for co...

A flexible electronic system may consist of a polymeric substrate and an array of stiff islands, on which devices are fabricated. When the substrate is stretched, the devices on the islands experience small strains but the islands may debond if they exceed a critical size. The authors show that a thin layer of polymer coating, covering the islands and the substrate, can markedly increase the cr...

This paper describes an innovative sensor system which can detect and track people in a room by means of an array of capacitive sensors beneath the floor covering. By combining cutting-edge technology from the domains of capacitive sensing, wireless data transmission, interconnecting technology between textiles and microelectronics and high level data processing it is possible to support variou...

Abstract The Tianlai Dish Pathfinder Array is a radio interferometer array consisting of 16 six-meter dish antennas. original digital backend integration time at the seconds level, designed for H i intensity mapping experiment. A new with millisecond response added to enable it search fast burst during its observations. design and calibration this backend, real pipeline are described in paper. ...

The pathogenesis of Lassa fever is poorly understood. As the liver is a major target organ of Lassa virus, gene expression in Lassa virus-infected HuH-7 cells, a differentiated human hepatoma cell line, was studied. Cellular mRNA levels were measured at the late phase of acute infection, when virtually all cells expressed large amounts of nucleoprotein, and virus RNA concentration had reached>1...

Widely used 1-D guided wave phased arrays can only scan within 0°~180° range due to the intrinsic structural limitation. To overcome this limitation, multiple installations are unavoidable. However, by using 2-D configuration phased arrays, large structural interrogation can be conducted from a single location with a single scanning covering the entire 0°~360° range through omnidirectional beam...
