Abstract: An authority control system includes a biometric identification unit, a near field communication (NFC) signal transmission unit, and an NFC signal receiving unit. The biometric identification unit stores associated data, configured to obtain first biometric data, obtains encoded data according to the first biometric data and the associated data, and transmits the encoded data. The NFC signal transmission unit is configured to receive the encoded data transmitted by the biometric identification unit, and transmit the encoded data by using an NFC transmission technology. The NFC signal receiving unit stores authorization type comparison data. The NFC signal receiving unit is configured to receive the encoded data transmitted by the NFC signal transmission unit, and determines an authorization type according to the encoded data and the authorization type comparison data.

Abstract: A photographing lens assembly includes at least four lens elements that are, in order from an object side to an image side along an optical path, a first lens element, a second lens element, at least one subsequent lens element and a last lens element that is closest to an image surface. Each of the at least four lens elements has an object-side surface facing toward the object side and an image-side surface facing toward the image side. At least one surface among lens surfaces from the image-side surface of the second lens element to the object-side surface of the last lens element is a metasurface having a subwavelength microstructure.

Abstract: A semiconductor device and method of manufacturing the same are provided. The semiconductor device includes a substrate and a gate structure disposed on the substrate. The semiconductor device also includes a source region and a drain region disposed within the substrate. The substrate includes a drift region laterally extending between the source region and the drain region. The semiconductor device further includes a first stressor layer disposed over the drift region of the substrate. The first stressor layer is configured to apply a first stress to the drift region of the substrate. In addition, the semiconductor device includes a second stressor layer disposed on the first stressor layer. The second stressor layer is configured to apply a second stress to the drift region of the substrate, and the first stress is opposite to the second stress.

Abstract: The invention relates to a microcarrier, comprising a continuous medium of a biocompatible polymer for culturing cells and having a three-dimensional scaffold architecture delineated peripherally by a continuous outer wall, in which spherical macropores are stacked to one another and interconnected by connecting pores. The continuous outer wall is formed with exposure pores at positions where it is in contact with the macropores, through which the interior of the microcarrier may be in fluid communication with the ambient culture medium. The microcarrier herein is produced by cast-molding and, therefore, has a continuous outer wall which provides additional mechanical strength while maintaining high porosity. The microcarrier thus produced is configured in the form of a basic geometrical body. The invention further relates to a cast-molding process for producing the microcarrier.
