Abstract: In order to solve the real-time positioning problem of flexible wearable ultrasonic transducer array unit under dynamic conditions, a new transducer array based on button flexible structure ...

Meta-holograms, the computer-generated holograms assisted with nano-structured metasurfaces, promise efficient recording of light at the nanoscale. Adopting the multiplexing principle further bestows ...

Direct-lit TVs have LED backlights that are always on, but they’re dotted around the TV, like full-array local dimming. This allows for more uniform backlighting, but without the ability to turn them ...

As a PowerShell developer, I'm often seeking to iterate thru a ratio of a list or string. For example, if I wanted to copy all half of the points in a Turtle, I have ...

Microsoft will remove PowerShell 2.0 from Windows starting in August, eight years after announcing its deprecation and keeping it around as an optional feature. The 14-year-old command processor ...

Abstract: A four-dimensional (4-D) antenna array with hemispherical spatial coverage is proposed for seamless connectivity over a wide area. The antenna array is composed of 4 sequentially rotated ...

A fringe new theory suggests that time is the fundamental structure of the physical universe, and space is merely a byproduct. According to Gunther Kletetschka, a geologist — not a physicist, you’ll ...

Time, not space plus time, might be the single fundamental property in which all physical phenomena occur, according to a new theory by a University of Alaska Fairbanks scientist. The theory also ...

Huzhou includes five districts and counties, each with distinct development characteristics: Anji County, characterized by a low economic level but a high forest coverage; Wuxing District has high ...
