Conventionally, text boxes are used to inform an image capture device of the size of an area to which a captured image will need to be scaled, when fitting the captured image into that area of the composite document. In contrast, size selection systems, methods and graphical user interfaces allow the user to select one of a number of predetermined sets of scale dimensions that the captured image is to be scaled to. The size selection systems, methods and graphical user interfaces provide an alternative method for specifying the dimensions that a captured image is to be scaled to. In various exemplary embodiments of the size selection systems, methods and graphical user interfaces, an image size tab of a graphical user interface for an image capture driver includes a scale portion. The scale portion, in addition to having a number of dimension boxes that allow the user to directly input the desired dimensions to which the captured image is to be scaled, also includes a dimension list box. The dimension list box includes predetermined sets of dimensions to which the captured image can be scaled. In various exemplary embodiments, the dimensions list box includes, as the predetermined sets, sets of dimensions for common paper sizes and sets of dimensions for different paper orientations. The predetermined sets of dimensions can also include sets of user-defined dimensions. These user-defined dimensions allow the user to specify the dimensions of an image area of a document that is often used.

The periodic stress and strain fields produced by a pure twist grain boundary between two single crystals bonded together in the form of a bicrystal are used to fabricate a two-dimensional surface topography with controllable, nanometer-scale feature spacings (e.g., from 50 nanometers down to 1.5 nanometers). The spacing of the features is controlled by the misorientation angle used during crystal bonding. One of the crystals is selected to be thin, on the order of 5-100 nanometers. A buried periodic array of screw dislocations is formed at the twist grain boundary. To bring the buried periodicity to the surface, the thin single crystal is etched to reveal an array of raised elements, such as pyramids, that have nanometer-scale dimensions. The process can be employed with numerous materials, such as gold, silicon and sapphire. In addition, the process can be used with different materials for each crystal such that a periodic array of misfit dislocations is formed at the interface between the two crystals.

The airports are periodically arranged in the optical fiber base material, the dimension of the airports is the wavelength magnitude, every three adjacent airport units constitute a regular triangle. The fiber core is jointly constituted by an optical fiber base material locating at the center part of the optical fiber end-face and another solid material, wherein, the refractivity of the solid material is higher than that of the optical fiber base material, two blocks of solid material are symmetric distributed at the both sides of the optical fiber end-face center and the minimum distance of their outer margins should be smaller than 400nm in order to produce a narrow slit.

Disclosed are a variety of junction termination structures for high voltage semiconductor power devices. The structures are specifically aimed at providing a high breakdown voltage while being constructed with a minimal number of process steps. The combination of an RIE etch and / or implantation and anneal process with a finely patterned mesh provides the desired radial gradient for maximum breakdown voltage. The structures provide control of both the conductivity and charge density within the region. These structures can beneficially be applied to all high voltage semiconductor device structures, but are of particular interest for wide bandgap devices as they tend to have very high breakdown fields and scaled dimensions of the depletion layer width.

Embodiments of the present invention employ complexly shaped, high-surface-area channels for separation and purification of molecules, including important biopolymers such as proteins, glycoproteins, polysaccharides, and other molecular components of living cells. The relatively large internal surface areas of the complexly shaped channels employed in embodiments of the present invention provide, in comparison to traditional, simply shaped separation channels, increased heat dissipation during electrokinetic separation, and a decreased tendency for bulk-solution flow. Heat dissipation prevents high temperatures that can denature proteins and that can induce thermal currents within the separation channel. Bulk-solution flow within a separation channel can overwhelm the generally linear, electrical-potential-induced migration of molecules that leads to efficient and well-resolved molecular separations. The complexly shaped channels employed in various embodiments of the present invention can be readily manufactured at microscale dimensions for use in microscale devices, at millimeter-scale dimensions for inclusion in microfluidics devices, and may also be used in larger scale, traditional separation and purification systems.
