Abstract:
The invention pertains to methods for protecting against malaria infection by vaccination. The method of the invention involves priming an anti-malaria immune response with a DNA-based vaccine, and boosting that response with a protein-based vaccine. The method of the invention also relates to broadening the resulting immune response by boosting with a protein-based vaccine.

Abstract:
Channel doping and gate lithography are simultaneously performed by focusing an ion beam into the wafer through a positive or negative photoresist that is sensitive to the ion beam. Additional fabrication is then performed to provide a gate that is self-aligned with the doped channel.
Abstract:
Patterned conducting polymer surfaces exhibiting excellent properties may be prepared by: (a) forming a surface of a conducting polymer on a surface of a substrate; (b) forming a surface of a blocking material on the surface of the conducting polymer in a patternwise fashion, to obtain a first patterned surface containing regions of exposed conducting polymer and regions of blocking material; (c) treating the first patterned surface with an agent which: (i) removes the conducting polymer from the regions of exposed conducting polymer; (ii) decreases the conductivity of the conducting polymer in the regions of exposed polymer; or (iii) increases the conductivity of the conducting polymer in the regions of exposed conducting polymer; and (d) removing the blocking material to obtain a second patterned surface containing an exposed pattern of conducting polymer.

Abstract:
A giant magnetoresistance displacement sensor includes at least one layered structure. This layered structure includes a harder magnetic (ferromagnetic or antiferromagnetic) layer (34) having a fixed magnetic state, a second, softer magnetic layer (32) and a metal layer (33) interposed between and contacting these two layers (32, 34) to prevent exchange coupling between the two layers. The sensor also includes means (56, 58) for inducing a domain wall (37) at a measurand position, between regions (35, 36) of nonaligned magnetic fields in the softer magnetic layer (32), and means (50) for measuring electrical resistance between points on opposite sides of the structure. In operation, the means (56, 58) for inducing a domain wall, typically one or more indexing magnets (56, 58), is positioned relative to the giant magnetoresistance strip. The resistance across the strip is measured, and from this resistance measurement the position of the domain wall is determined. The present invention is also a variable resistor, which is operated by positioning the means (56, 58) for inducing the domain wall at a selected position, to set the resistance across the strip to a desired value.
Abstract:
An optical system for detecting perturbations indicative of the performance of the piece of equipment being monitored is disclosed. The optical system comprises sensors (12), each of which uses Bragg gratings (12A-12N), induced therein and wherein the Bragg gratings (12A-12N) are arranged into a preselected distribution and each Bragg grating returns, when subjected to incident light, a narrowbeam signal (22, 24, 26) identified by a predetermined wavelength. The optical system utilizes at least one interferometer (56) whose operation is interlinked with optical multiplexing techniques, such as differentiate-cross-multiplying and time-division multiplexing.
Abstract:
A core glass rod (32) is placed within clad glass tube (34). The bottom of the tube is sealed (40) to the bottom of the rod with heater (36). The space (39) between the rod and tube is evacuated (38). Then the top of the tube is sealed to the top of the rod to form a preform (44). This preform is then hot isostatically pressed (46) to obtain an optical fiber preform. Soot and bubble presence is eliminated or reduced.
