  • Patent number: 11939345
    Abstract: A physiologically stable fluorophore includes a terminal moiety including a terminal reactive site that reacts with a reactive group of a substrate; a stability linker covalently bonded to the terminal moiety; and a bridge moiety covalently bonded to the stability linker such that the stability linker is interposed through chemical bonds between the bridge moiety and the terminal moiety; and a fluorescent moiety covalently bonded to the bridge moiety of the redox moiety and including: an electron bandgap mediator that is covalently bonded to the bridge moiety; a coordinate center covalently bonded to the electron bandgap mediator and that forms a Zwitterionic member with an atom in the electron bandgap mediator; and a steric hinder bonded to the electron bandgap mediator to provide steric hindrance for protection of the coordinate center.

  • Patent number: 11882655
    Abstract: A high-speed transmission circuit comprises, as part of a signal path, a connector pin disposed on a pad that comprises an unused pad region. The unused pad region is not considered part of the signal path but is part of a resonant sub-circuit. In various embodiments, by properly adjusting the dimensions of the pad region and other structures in the high-speed transmission circuit, resonant frequencies of the sub-circuit are shifted to a frequency range that is outside of the frequency range of interest in the signal path, thereby, reducing insertion loss and increasing signal integrity without compromising mechanical stability.

  • Patent number: 7412351
    Abstract: A method for monitoring the activity of a tape drive system having one or more electro-mechanical components that receive electrical current from a power supply. The method includes sampling an actual current supplied to an electro-mechanical component of a tape drive system from a power supply during an activity; reading a theoretical current for said activity from a memory; calculating a statistical value for said actual current and said theoretical current; comparing said statistical value to at least one threshold value; and outputting information to at least one of a user, another system, and another process based on said comparison of said statistical value to said at least one threshold value.

  • Patent number: 7302570
    Abstract: An apparatus, system, and method are provided for authorized remote access to a target system. The apparatus, system, and method include a security module and an authorization module that cooperate to authenticate a remote user using three passwords. The apparatus, system, and method selectively generate an encrypted key in response to a first password. The authorization module decrypts the encrypted key and determines a third password in response to authenticating a second password and identifying a remote user within an authorized user list. The third password is then used to gain secure, traceable, and in certain embodiments, restricted remote access to a target system.

  • Patent number: 7231317
    Abstract: A method and system for monitoring the activity of a system of one or more electro-mechanical components that receive electrical current from a power supply. The method and system samples an actual current supplied to the electro-mechanical component from the power supply. Next, the method and system reads a theoretical current for the activity of the system. A statistical value is computed from comparing the actual current and the theoretical current. This statistical value is compared to upper and lower threshold values. Depending upon this comparison, the system issues various output messages. Further, if this comparison indicates that one of the electro-mechanical components is failing, the method and system will shut that component down.

  • Publication number: 20060099578
    Abstract: This invention provides a library of genes involved in mitochondrial biology, arrays containing probes for genes involved in mitochondrial biology, methods for making such arrays, and methods of using such arrays. Genes and probe sequences involved in mitochondrial biology in humans and mice are provided. The arrays of this invention are useful for determining mitochondrial biology gene expression profiles. Mitochondrial biology gene expression profiles are useful for determining expression profiles diagnostic of physiological conditions; diagnosing physiological conditions; identifying biochemical pathways, genes, and mutations involved in physiological conditions; identify therapeutic agents useful for preventing and/or treating such physiological conditions; evaluating and/or monitoring the efficacy of such therapies, and creating and identifying animal models of human physiologic conditions.

  • Publication number: 20050123913
    Abstract: This invention provides human mtDNA polymorphisms that are diagnostic of all the major human haplogroups and methods of diagnosing those haplogroups and selected subhaplogroups. This invention also provides methods for identifying evolutionarily significant mitochondrial DNA genes, nucleotide alleles, and amino acid alleles. Evolutionarily significant genes and alleles are identified using one or two populations of a single species. The process of identifying evolutionarily significant nucleotide alleles involves identifying evolutionarily significant genes and then evolutionarily significant nucleotide alleles in those genes, and identifying evolutionarily significant amino acid alleles involves identifying amino acids encoded by all nonsynonymous alleles. Synonymous codings of the nucleotide alleles encoding evolutionarily significant amino acid alleles of this invention are equivalent to the evolutionarily significant amino acid alleles disclosed herein and are included within the scope of this invention.

  • Publication number: 20050091704
    Abstract: Described are methods for inactivating adenine nucleotide transporter proteins in specific tissues of a transgenic nonhuman animal using a conditional knockin/knockout technology such as the Cre-LoxP, Flip-FLP recombinase, or Tet-on/off technologies. Specifically, the Ant2 gene is functionally inactivated in a mouse in liver, with or without the concurrent inactivation of the Ant1 gene. The result is an animal in which the Ant2 gene and accompanying ANT2 protein is absent in one or more tissues, either in the presence or absence of the Ant1 gene and accompanying ANT1 protein. The resulting animals, cells, mitochondria, and subcelluar fractions such as the mitochondrial permeability transition pore can then be used to identify agents that affect animal and/or subcellular function via a direct or indirect interaction with the ANT2 protein and/or its Ant2 gene.

  • Patent number: 6688889
    Abstract: A computerized test preparation system and methods are disclosed which assist an examinee to increase his learning and improve his performance on standardized academic or applied aptitude and achievement exams. Performance feedback information is provided to a user, including conventional information such as number of items correct and time elapsed, pinpoints substantive areas of a particular exam in which the user is either weak or strong, and offers diagnoses of, and remediation tailored to, a user's personal difficulties. By assessing a user's responses to given exam questions, through various distractor error patterns manifested in the incorrect answers to multiple-choice questions, or through coded categories of responses in the case of user responses to constrained open-ended items, a preliminary diagnosis of a user's deficits in knowledge and/or test taking skill is made. This preliminary diagnosis is subsequently refined utilizing additional examination questions.
