    摘要: A cavity ring-down system for performing cavity ring-down spectroscopy (CRDS) using optical heterodyne detection of a ring-down wave E RD during a ring-down phase or a ring-up wave E RU during a ring up phase. The system sends a local oscillator wave E LO and a signal wave E SIGNAL to the cavity, preferably a ring resonator, and derives an interference signal from the combined local oscillator wave E LO and the ring-down wave E RD (or ring-up wave E RU ). The local oscillator wave E LO has a first polarization and the ring-down wave E RD has a second polarization different from the first polarization. The system has a combining arrangement for combining or overlapping local oscillator wave E LO and the ring-down wave E RD at a photodetector, which receives the interference signal and generates a heterodyne current I H therefrom. Frequency and phase difference between the waves are adjustable.

    摘要: Methods and devices for preventing a change in the core body temperature of a mammal under cold conditions are provided. In the subject methods, a requirement for thermal energy input in said mammal is first detected. In response to the detection of this requirement for thermal energy input, a surface of a portion of the mammal is contacted with a warm temperature medium under negative pressure conditions for a period of time sufficient to introduce thermal energy into the core body of the mammal. The subject devices include at least a means for detecting a requirement for thermal energy input and a means for contacting a surface of a mammal with a warm temperature medium under negative pressure conditions (104). The subject methods and devices find use in a variety of applications, and are particularly suited for use in maintaining the core body temperature of a mammal substantially under cold conditions for an extended period of time.

    摘要: Parallel hybridization analysis is used to detection and analyze allelic variation between two closely related genomic nucleic acid samples. Nucleic acid samples from both sources are cleaved to generate short fragments. The fragments are end-labeled, and then hybridized to a high density oligonucleotide array. Hybridization patterns for the two samples are detected, normalized and compared. Those positions on the array that correspond to sequences with allelic variation between the two samples show decreased hybridization efficiency for one of the samples relative to the other. A map of allelic variation can be generated with this information, and used for genetic linkage analysis, determination of chromosomal regions having low diversity or high diversity, forensic studies, etc.
