    • A method and system are provided for comparing ordered segments of a first DNA restriction map with ordered segments of a second DNA restriction map to determine a level of accuracy the first DNA map and/or the second DNA map. In particular, the first and second DNA maps can be received (the first DNA map corresponding to a sequence DNA map, and the second DNA map corresponding to a genomic consensus DNA map as provided in an optical DNA map). Then, the accuracy of the first DNA map and/or the second DNA map is validated based on information associated with the first and second DNA maps. In addition, a method and system are provided for aligning a plurality of DNA sequences with a ordered DNA restriction map. The DNA sequences and the DNA map are received (the DNA sequences being fragments of a genome and the DNA map corresponding to a genomic consensus DNA map which relates to an optical ordered DNA map). Then, a level of accuracy of the DNA sequences and the DNA map is obtained based on information associated with the DNA sequences and the DNA map by means of the method and system described above. The locations of the DNA map at which the DNA sequences are capable of being associated with particular segments of the DNA map are located. Furthermore, it is possible to obtain locations of the DNA map (without the validation) by locating an optimal one of the locations for each of the DNA sequences for each of the locations.

    • A method for observing and determining the size of individual molecules and for determining the weight distribution of a sample containing molecules of varying size, which involves placing a deformable or nondeformable molecule, in a medium, subjecting the molecule to an external force, thereby causing conformational and/or positional changes, and then measuring these changes. Preferred ways to measure conformational and positional changes include: (1) determining the rate at which a deformable molecule returns to a relaxed state after termination of the external force, (2) determining the rate at which a molecule becomes oriented in a new direction when the direction of the perturbing force is changed, (3) determining the rate at which a molecule rotates, (4) measuring the length of a molecule, particularly when it is at least partially stretched, or (5) measuring at least one diameter of a spherical or ellipsoidal molecule. Measurements of relaxation, reorientation, and rotation rates, as well as length and diameter can be made using a light microscope connected to an image processor. Molecule relaxation, reorientation and rotation also can be determined using a microscope combined with a spectroscopic device. The invention is particularly useful for measuring polymer molecules, such as nucleic acids, and can be used to determine the size and map location of restriction digests. Breakage of large polymer molecules mounted on a microscope slide is prevented by condensing the molecules before mounting and unfolding the molecules after they have been placed in a matrix.

    • A litter box assembly is described that comprises a box for containing litter, having a base, rigid side walls, an opening in one of the side walls, and a removable lid atop the side walls; and a flexible tunnel, preferably made of an accordion plastic. The tunnel allows for the ingress and egress of a small animal, preferably a “so-called” indoor pet such as a cat, and supports the weight of the small animal during its ingress and egress to and from the litter box. The tunnel is preferably suspended above the ground via removable attachments to the opening in the litter box, the to an opening in a residence. The litter box is not fixed in a particular orientation relative to the opening in the residence, even when connected to the tunnel. The litter box is preferably substantially divided, by an interior wall, into a waste chamber for containing litter and an interior passageway. The interior passageway may comprises holes on the floor to allow the passage of litter through the holes during ingress and egress of the animal, but small enough to prevent passage of the feet of the animal through the holes. The rigid side walls of the litter box may also comprise wall holes, which may be covered by overhangs, where the wall holes are of a size to permit the free flow of air and gases into and out of the litter box, and small enough to prevent passage of the animal from the litter box through the holes.
    • 描述了一种垃圾箱组件,其包括用于容纳垃圾的箱体,其具有基部,刚性侧壁,一个侧壁中的开口和在侧壁顶部的可移除盖; 以及优选由手风琴塑料制成的柔性隧道。 该隧道允许小型动物,优选地是所谓的“猫”等室内宠物的入口和出口,并且在进入和离开垃圾箱的过程中支撑小动物的重量。 隧道优选通过可移除的附件悬挂在地面上的垃圾箱中的开口,到居住地的开口处。 即使连接到隧道,垃圾箱也不会相对于住宅内的开口以特定方向固定。 垃圾箱优选地通过内壁大体分成用于容纳垃圾和内部通道的废物室。 内部通道可以包括在地板上的孔,以允许垃圾在进入和移出动物期间通过孔,但足够小以防止动物的脚通过孔。 垃圾箱的刚性侧壁还可以包括壁孔,其可以被悬垂物覆盖,其中壁孔的大小允许空气和气体自由流入和排出垃圾箱,并且足够小到 防止动物从垃圾箱通过孔。

    • A lightweight, portable, interchangeable and effective overlay plate that will increase the efficiency of brachytherapy radiation treatment and reduce the duration of the radiation exposure during the radioactive seed insertion and positioning in brachytherapy. The overlay plate has a limited number of apertures specific to the treatment of a particular patient and is attached to the matrix used to position and guide the needles with the radioactive seeds. The apertures of the overlay plate may further be truncated-cone-shaped, with the narrow ends aligned with corresponding apertures in the matrix and the flared ends facing the user. The overlay plate minimizes the radiation exposure as much as reasonably possible because any amount of radiation exposure carries a risk to the exposed individual, and the overlay plate may also be manufactured from radiation-protective material to further minimize the radiation exposure.

    • A system and method for installing and removing a flow restrictor assembly in a shower, while prevents tampering with the flow restriction system thus installed. Tampering is prevented by concealing the flow restrictor assembly behind a shower wall, attached directly to a water supply line. The system further prevents tampering by concealing the tool-hole necessary for its removal behind a flow restrictor disk, so that there are no visible means of removing the flow restrictor assembly. The flow restrictor assembly threads onto a showerhead arm and the flow restrictor assembly with the attached showerhead arm threads directly into the water line. When the showerhead arm is unthreaded, the flow restrictor assembly remains connected to the water line by an external screw thread. The flow restrictor must be removed to reveal the tool-hole which may only then be engaged by a tool for removal.
