Method and apparatus establishing forwarding state using path state advertisements
Paths may be advertised on a network implementing a link state routing protocol by using path state advertisement that are distributed in the same manner as link state advertisements. The path state advertisements contain path entries, each of which includes a globally unique path ID and path information such as a series of nodes or links that defines the path through the network. When a path state advertisement is received by a network element, the network element will evaluate the path entries in the path state advertisement to determine if the path state advertisement is relevant and, if necessary, install forwarding state for the relevant path entries. Path state advertisements not relevant to a network element are not used to affect forwarding state on the network element. Label based forwarding may then be used by the network elements to forward data along the path, in which the globally unique path ID is used as the label for the data. |

Personal dosimeter on the base of radiation integrated circuit
This invention provides a radiation dosimeter and new method of operation which comprise two types of the metal-oxide-semiconductor field-effect transistor (MOSFET) circuits allowing to amplify the threshold voltage changes due to radiation and provide temperature compensation. The first type dosimeter is a radiation integrated circuit (RADIC) which includes two radiation field-effect transistors (RADFET) and two MOSFETs, integrated into the same substrate. The second type of radiation circuit includes two RADFETs, integrated into the same substrate, and two resistors. The amplification of the threshold voltage change is achieved by using amplification principles of an MOSFET inverter. In both cases, under the ionizing irradiation, the gate of first RADFET is forward biased and the gate of second RADFET is biased off. In the reading mode the amplified differential threshold voltage change is measured. The increased radiation sensitivity allows to measure of the milli-rad doses. The temperature effect and drift is substantially eliminated. These radiation integrated circuits can be used as a personal dosimeter in the nuclear, industrial and medical fields. |

Fragmentation of analyte ions by collisions in RF ion traps
Analyte ions, particularly biopolymer ions, stored in an RF ion trap are ergodically fragmented by bombarding the analyte ions with collision ions, for example medium-mass, mono-atomic ions having a charge of opposite polarity to the charge of the analyte ions. Since the analyte ions are not fragmented by accelerating and/or exciting them to oscillations, as is the case with conventional collision-induced dissociation, the RF voltage of the ion trap can be set low enough that daughter ions with light charge-related masses that are produced by the fragmentation can also remain trapped in the ion trap. |

Identification of novel genes coding for small temporal RNAS
In Caenorhabditis elegans, lin-4 and let-7 enclode 22- and 21 -nucleotide RNAs, respectively, that function as key regulators of developmental timing. Because the appearance of these short RNAs is regulated during development, they are also referred to as “small temporal RNAs” (stRNAs).

This suggests that sequence-specific post-transcriptional regulatory mechanisms mediated by small RNAs are more general than previously appreciated. |
