Abstract: Electron multipliers, radiation detectors, and methods of making the multipliers and detectors are described. In some embodiments an electron multiplier has a structure including a plurality of interconnected fibers having electron-emissive surfaces, the fibers having a width to thickness aspect ratio greater than one.

Abstract: A system and method for collaborative call management are disclosed. In one embodiment of a method incorporating teachings of the present disclosure, a graphical user interface (GUI) element may be presented in connection with a collaborative call. The GUI element may display a listing of call participants and a status of each participant. Example participant states may include an on-call state, an off-call state, a currently speaking state, a waiting to speak state, and a paused-call state. In operation, information presented in the GUI element may change in response to a status change of a call participant. The method may also involve recognizing that a caller has joined the collaborative call and updating the GUI element to add the joining caller to the list of participants.

Abstract: A method for generating address/capture tags for use in a sensitive and rapid flow-cytometry based assay for the multiplexed analysis of SNPs based on polymerase-mediated primer extension using microspheres as solid supports is described. Single-nucleotide polymorphisms (SNPs) are the most abundant type of human genetic variation. These variable sites are present at high density in the genome, making them powerful tools for mapping and diagnosing disease-related alleles. Subnanomolar concentrations of sample in small volumes (10 ml) can be analyzed at rates greater than one sample per minute, without a wash step. Genomic analysis using multiplexing microsphere arrays, enables the simultaneous analysis of dozens, and potentially hundreds of SNPs per sample. The method has been tested by genotyping the Glu69 variant from the HLA DPB1 locus, a SNP associated with chronic beryllium disease, as well as HLA DPA1 alleles.

Abstract: An electron multiplier includes a plate having a plurality of interconnected particles, e.g., fibers, having electron-emissive surfaces. The particles may include a neutron-sensitive and/or neutron reactive material, such as 6Li, 10B, 155Gd, 157Gd,—and/or hydrogenous compounds, in excess of their natural abundance. The particles may include an X-ray sensitive and/or X-ray reactive material, such as Pb.
