Abstract: Fluorogenic peptide probes specific for a target molecule are provided. Exemplary fluorogenic peptide probes include a peptide labeled with a fluorogenic label, wherein the fluorogenic peptide probe has an unstructured three dimensional conformation in the absence of the target molecule and a structured three dimensional conformation in the presence of the target polypeptide. The structured three dimensional conformation includes an alpha-helix that forms a coiled-coil with the target molecule allowing generation of a detectable signal from the fluorogenic label in response to an exciting amount of radiation.

Abstract: A new signal amplification method exploiting the dense atom packing in metallic nanocrystals has been developed for detecting target substances. By dissolving nanocrystals to individual ions that are stoichiometrically converted to chromophores and quantified photometrically, extremely high signal amplification can be achieved. Signal amplification is fully determined by the total number of atoms in the nanocrystals bound to a single target molecule. The disclosed nanocrystal amplification method can be implemented with a rich selection of metal/metal oxide nanocrystals and metal-reactive chromogenic substrates.

Abstract: A network entity may dynamically control Quality-of-Service (QoS) for a multicast transmission in a wireless communications system, by initiating a multicast transmission having an initial QoS, and later during the multicast transmission, generating an updated QoS for the multicast transmission. The network entity may generate the updated QoS in response to a network load factor for a multicast area aggregated from base stations in the area. The network load factor may indicate a measure of aggregate available bandwidth in the multicast area. The network entity may provide the updated QoS to mobile entities receiving the multicast transmission, which may process a subsequent portion of multicast content according to the updated QoS.

Abstract: An efficient use of communication resources is provided by determining a behavior for selecting the payload size (data rate) of a reverse link transmission from a mobile station to a base station. The mobile station may store a predetermined table including the ratio of the power levels of the traffic channel and pilot channel (TPR), where each entry corresponds to one or more specific sizes of data payload, and consequently a data rate for transmission in a predetermined time frame. The payload size is selected based on an authorized-TPR. The authorized-TPR and a target-TPR are adjusted in accordance with a value of common TPR commands received from the base station. A fast-ramp-up behavior for adjustments of the authorized-TPR is followed when the authorized-TPR is less than the target-TPR. The down TPR commands are ignored in the adjustments of the authorized-TPR to allow following a fast-ramp-up behavior.

Abstract: Apparatus and methods efficiently estimate signal-to-noise ratios of a received signal irrespective of intentional adjustments to transmitting power due to fluctuating data rates. For example, in one embodiment, the variation in power due to the change in data rate is decoupled from environmental sources for variations in power. In one embodiment, the signal to noise ratio is adjusted for the data rate. In another embodiment, another signal is used as a reference for the signal to noise computation. This advantageously permits a system to efficiently and accurately control power in a power control loop for efficient use of spectral bandwidth and for relatively good grade of service (GoS).
