Abstract:
Methods to expand polymer tubing with desirable or optimum morphology and mechanical properties for stent manufacture and fabrication of a stent therefrom are disclosed.
Abstract:
A flash memory is provided. The flash memory features of having the select gate transistors to include two different channel structures, which are a recessed channel structure and a horizontal channel. Because of the design of the recessed channel structure, the space between the gate conductor lines, which are for interconnecting the select gates of the select gate transistors arranged on the same column, can be shortened. Therefore, the integration of the flash memory can be increased; and the process window of the STI process can be increased as well. In addition, at least one depletion-mode select gate transistor is at one side of the memory cell string. The select gate transistor of the depletion-mode is always turned on.
Abstract:
Disclosed is a method of treating a bodily lumen with a stent, the method comprising: disposing a stent within a bodily lumen, the stent comprising a plurality of deformable struts that are substantially circumferentially aligned and are configured to selectively deform in a circumferential direction in localized regions in the struts upon application of an outward radial force; and expanding the stent by applying the outward radial force, wherein the outward radial force causes selective deformation of the deformable struts in a localized region in the struts.
Abstract:
An indium oxide based material containing carbon, and a method for preparing the same are provided. In such a method, the carbon is added to the indium oxide based material film so that the electrical resistivity of the indium oxide based material film is decreased, and the light transmittance of the indium oxide based material in the shorter wavelength range is increased, and also the light can transmit through such a material over a broader short wavelength range. The indium oxide based material prepared by the method of the present invention has higher electrical conductivity and higher light transmittance in comparison with the conventional one without adding carbon.
Abstract:
The invention provides a monitoring device mainly for sensing ground displacement, including the fiber Bragg grating sensored deflectometer and the signal interrogator/computer system. The device uses a segmented design that consists of a flexible tube (referred to as the flexible segment) and two rigid segments and thus referred to as the double hinged FBG segmented deflectometer (DH-FBG-SD). For field installation, multiple DH-FBG-SD units are connected together to form a string as it is inserted into a grouted-in-place inclinometer casing. The distortion of the inclinometer casing induced by ground movement causes relative rotation of the inserted DH-FBG-SD. All of the DH-FBG-SD units are connected to an FBG interrogator/computer system situated on ground surface. The FBG signals are recorded and analyzed by the interrogator/computer system.
Abstract:
A cellular culture chip device includes a chip body. The chip body includes: a first flow channel having a first inlet end and a first outlet end and adapted to direct a liquid nutrient; a second flow channel adapted to direct a gellable culture medium; a medium retaining hole fluidly connected to the second flow channel and adapted to retain the gellable culture medium, the medium retaining hole having an opening connected fluidly to the first flow channel and adapted to expose the gellable culture medium to the liquid nutrient flowing through the first flow channel; a pump membrane adapted to control the flow of the liquid nutrient within the first flow channel; and a pressure channel unit to operate the pump membrane.
