The gallium nitride epitaxial layer is formed on a surface, a thickness of the gallium nitride epitaxial layer is less than 2 ?m, and a full width at half maximum (FWHM) of an X-ray diffraction analysis (002) plane is less than 100 arcsec. The thickness of the high-resistivity silicon carbide layer ranges from 20 ?m to 50 ?m. The surface of the high-resistivity silicon carbide layer has an angle ranging from 0° to +/?8° with respect to a (0001) plane. The micropipe density (MPD) of the high-resistivity silicon carbide layer is less than 0.5 ea/cm2, the basal plane dislocation (BPD) of the high-resistivity silicon carbide layer is less than 10 ea/cm2, and the threading screw dislocation (TSD) of the high-resistivity silicon carbide layer is less than 500 ea/cm2.

Abstract: An improved structure of a picture display frame comprising a framework, a picture and a grating plate, wherein the picture has more than one image, and is assembled with the grating plate in the framework. The grating plate has a smooth plane surface facing outwards of the framework and has an undulated surface formed from a series of columns facing inwards of the framework and are opposite to the picture spaced therefrom, a gap is formed between the picture and the grating plate; the gap is set to be equal to depth of focusing of the columns of the grating plate formed in refraction of light beams. The surface of the grating plate can be applied by spraying with scraping durable paint, it needs not to increase the thickness of the grating plate for having a deep focus and a good stereographic effect, this largely reduces the cost of the grating plate.

Abstract: An animation continuously displaying frame comprising at least a framework, a picture sheet, a grating plate as well as a combination member composed of a round rotating member with an eccentric hole and a movably mounted motor; the picture sheet and the grating plate are assembled in the framework to change positions or angular positions of the picture sheet or the grating plate by means of the round rotating member eccentrically mounted on a rotating axle of the motor and driven by the motor, thereby an effect of automatically changing the pictures on the grating plate can be obtained.

Abstract: A display frame for two pictures changing at fixed positions used as a picture frame or an advertisement billboard, it comprises a framework, two pictures, a grating plate, at least a magnet, an electric power source, a control circuit board and at least a coil; the pictures and the grating plate are assembled in the framework, the coil generates a specific magnetic force for moving the magnet, and angular positions of the pictures and the grating plate are changed, thereby effects that the two pictures on the grating plate are automatically changed and entirely presented in prolonged times are achieved.

Abstract: A display frame for changing of multiple pictures used as a picture frame or an advertisement billboard, it comprises in an assembly of a framework, multiple pictures, a grating plate and a movably mounted motor; the pictures and the grating plate are assembled in the framework, a leaf of specific shape is driven by the motor to change the positions or angular positions of a picture sheet or the grating plate, thereby effects that the pictures on the grating plate are automatically changed and entirely presented in prolonged times are achieved.

Abstract: A motion frame for pictures comprising a frame with which a grating plate and pictures are tightly compressed together, and a frame stand having thereon a motor of which the level can be adjusted; the frame is assembled on the frame stand, a specific shaped leaf driven by the motor can fast change the inclined angular position of the frame, and an effect that pictures are automatically changed and entirely presented in long durations can be achieved.

Abstract: The present invention relates to a method of detecting and monitoring genomic instability in a cell using three-dimensional analysis to assess telomeric and/or chromosomal organization. In addition, the invention relates to a method and system for characterizing the 3D organization of telomeres and/or chromosomes. The system includes an input module for inputting image data of the 3D organization of telomeres and/or chromosomes and a characteristic module for finding a parameter of the 3D organization. The invention also relates to the use of the three-dimensional analysis to detect, diagnose or monitor disease, particularly proliferative diseases such as cancer.

Abstract: An animation frame including a front frame body, a back plate installed therein with a grating plate and frame brackets, a moveable plane plate stuck with pictures, a battery, an IC circuit board and coils etc. The grating plate is placed on the pictures on the plane plate and fixed on a main body of the back plate; the plane plate has two notches respectively on its upper and lower edges, a vertical plane perpendicular to the plane plate has thereon a magnet between the two coils of the main body. The main body has thereon a movable device connecting with a movable screw and being fixed or adjusted to slide left or right to adjust the angular position of the plane plate. The main body has therein two movable screws connectable with the main body to adjust the plane plate in up and down moving.
