    • An optical fingerprinting method extracts high quality latent fingerprints from a surface without any invasive chemical or physical contact with the examined object, and requires no cooperation of the subject. Rather than employing extraneous material, the optical properties of the latent fingerprint are used to generate one or more images with sufficient contrast to distinguish the latent fingerprint or some other deformation in the surface. The system includes a light source oriented to apply light at an angle of incidence to the surface at the position to be examined for the latent fingerprint or deformation, a camera oriented to receive light specularly and diffusely reflected from the surface and/or by the fingerprint or deformation on the surface, and a processor that performs the computation for digital contrast enhancement and/or reprojection of the recovered fingerprint image to a frontal view if necessary. The technique uses optical polarization properties to enhance the images by placing a linearly polarized filter(s) in front of the observing camera. At least two pictures of the same scene with the same lighting and view angle arrangement are taken whereby each of the pictures differ only in that the orientations of the polarization filter are different. At least two light polarization parameters for each pixel are computed from the two or more images taken with different polarizer orientations. An image with each pixel value representing the value of one of the polarization parameters or a function of the polarization parameters is generated and displayed, with some digital contrast enhancement and/or reprojection applied. The hidden latent fingerprint pattern is revealed in at least one such image with the interfering background pattern significantly suppressed.
    • 光学指纹法从表面提取高质量的潜在指纹,而不会与被检查物体进行任何侵入性化学或物理接触,并且不需要对象的协作。 不是使用外来材料,潜在指纹的光学性质被用于产生具有足够对比度的一个或多个图像以区分潜在指纹或表面中的一些其它变形。 该系统包括光源,该光源定向成以与潜在指纹或变形的待检查位置处的表面成角度地施加光,照相机,其被定向成从镜面反射并从表面漫反射和/或指纹 或变形,以及处理器,如果需要,则将恢复的指纹图像的数字对比度增强和/或再投影执行到正面视图。 该技术使用光学偏振特性来通过在观察相机的前面放置线性偏振滤光器来增强图像。 拍摄具有相同照明和视角配置的相同场景的至少两幅照片,由此每幅照片的差异仅在于偏振滤光片的取向不同。 从使用不同偏振器取向拍摄的两个或更多个图像计算每个像素的至少两个光偏振参数。 生成并显示具有表示极化参数之一的值的每个像素值的图像或者偏振参数的函数,并且应用一些数字对比度增强和/或重新投影。 隐藏的潜在指纹图案在至少一个这样的图像中被显露,其中干扰背景图案被显着抑制。

    • Proviral plasmids contain a modular gene expression cassette with one or a combination of (i) a wildtype 5′ AAV2 ITR sequence flanked by unique restriction sites that permit ready removal or replacement of said ITR; (ii) a promoter flanked by unique restriction sites that permit ready removal or replacement of the entire promoter sequence; (iii) a polylinker sequence that permits insertion of a gene coding sequence without modification thereof, wherein the gene is operatively linked to, and under the regulatory control of, the aforementioned promoter; (iv) a bovine growth hormone polyadenylation sequence flanked by unique restriction sites that permit ready removal or replacement of said polyA sequence; and (v) a wildtype 3′ AAV2 ITR sequence flanked by unique restriction sites that permit ready removal or replacement of the 3′ ITR. These plasmids enable rapid manipulation of the components of the cassette, e.g., rapid mutation and/or replacement of any component, and thereby increase the efficiency of recombinant viral vector, e.g., rAAV, production.

    • The present invention relates to the synthesis of functional human hemoglobin and other proteins in erythroid tissues of transgenic non-human animals and erythroid cell lines. It is based on the discovery that two of the five hypersensitivity sites of the .beta.-globin locus are sufficient to result in high level expression of human .alpha.- or .beta.-globin transgenes. The present invention also provides for novel recombinant nucleic acid vectors which may be used to produce .alpha.-globin as well as other proteins of interest in quantity in the red blood cells of transgenic animals or cell cultures of erythroid lineage. The vectors of the invention comprise at least one of the major DNase I hypersensitivity sites associated with the .beta.-globin locus together with a gene of interest. In a specific embodiment of the invention, a vector which comprises two DNase I hypersensitivity sites together with the human .alpha.-globin gene is used to create transgenic animals which produce human .alpha.-globin protein in erythroid tissues, including red blood cells. In a preferred specific embodiment of the invention, transgenic animals are created which comprise human .alpha.-globin and .beta.-globin genes, each under the transcriptional influence of two .beta.-globin locus DNase hypersensitivity sites; these transgenic animals express human hemoglobin in their erythroid tissues, and can be used to produce human hemoglobin in quantity.
