Abstract: Injectable acoustic tags and a process of making are described for tracking host animals in up to three dimensions. The injectable acoustic tags reduce adverse biological effects and have a reduced cost of manufacture compared with conventional surgically implanted tags. The injectable tags are powered by a single power source with a lifetime of greater than 30 days. The injectable tags have an enhanced acoustic signal transmission range that enhances detection probability for tracking of host animals.

Abstract: The invention relates to a double-stranded ribonucleic acid (dsRNA) for inhibiting the expression of the CD45 gene.

Abstract: The invention provides antisense antiviral compounds and methods of their use and production in inhibition of growth of viruses of the Filoviridae family, and in the treatment of a viral infection. The compounds and methods relate to the treatment of viral infections in mammals including primates by Ebola and Marburg viruses. The antisense antiviral compounds are morpholino oligonucleotides having: a) a nuclease resistant backbone, b) 15-40 nucleotide bases, and c) a targeting sequence of at least 15 bases in length that hybridizes to a target region selected from the following: i) the Ebola virus AUG start site region of VP24; ii) the Ebola virus AUG start site region of VP35; iii) the Marburg virus AUG start site region of VP24; or iv) the Marburg virus AUG start site region of NP.

The invention also provides isolated nucleic acid molecules encoding the placental P. falciparum polypeptides of the invention, compositions comprising one or more placental P. falciparum polypeptides of the invention, methods for inducing an immune response against the placental P. falciparum polypeptides, and methods for treating and diagnosing placental malaria.

Abstract: A system for determining polarization profiles of points in a scene from video frames using Stokes parameters includes a scene having a region that emits scene light rays that correspond to the points in the scene, an optical chopper controller, a rotating Stokes filter wheel that includes five trigger holes, three rotating linear polarizers, a circular polarizer, and a reference screen, a color filter, a video camera having a video frame, and a computer system having a frame grabber apparatus. The scene light rays are transmitted through the Stokes filter and the color filter to the video camera.

Abstract: The mass of stockpiled materials is determined from detailed measurements of the elevation of the pile surface at many points and the measurement of the gravitational field along several profile lines across the surface of the stockpiled material. The elevation measurements allow the calculation of the pile volume. Measured gravity values are adjusted using standard gravity corrections in such a manner as to imply all gravity data are collected along the same reference datum. Variations in the corrected gravity values are assumed to be caused solely by the pile material. The gravity measurements are interpreted using analytical and statistical methods to determine the volume-average bulk density value of the pile material. The pile volume is multiplied by the volume-average bulk density to obtain the weight of the stockpiled material.

Abstract: A non-magnetic compass for use in a moving military land vehicle, comprising a rapidly rotating platform having a north star-seeking columnar element that carries a sun-seeking telescope. Fibre optic bundles transmit sun rays from the telescope to a selected light sensor in a stationary circular sensor system concentric with the platform rotational axis. During one instant during each rotating cycle of the platform the telescope will sight the sun while the columnar element is simultaneously oriented to the north star; light rays are transmitted from the scope to a north-oriented sensor in the sensor system. The columnar element and telescope are periodically adjusted to take into account the geographical location of the vehicle and time of year.
