Abstract: Disclosed is a system and method for individualized hearing aid prescription which consists of a test procedure that enables the fitting of an individualized estimation of the SII model to individual listeners efficiently and an optimization process which translates the resulting individualized model to the prescribed gains across frequencies for programming into the user's hearing aids. The test involves the recognition of one or more words presented in background noise, which better approximates the daily listening experiences of hearing-aid users compared to the pure-tone detection in a silent environment task which is commonly utilized during conventional audiometric testing. In the estimated SII model, five parameters describe in a custom fashion the relative weights of speech information across the five frequency bands for a given listener. The results from the speech test is used to determine the desirable amount of gain for each frequency region to optimize the user's aided speech intelligibility.

Abstract: An electrostatic linear ion trap has first and second axially aligned ion mirrors separated by a charge detection cylinder axially aligned with each ion mirror. Electric fields are selectively established within the first and second ion mirrors in a manner which causes an ion in the trap to oscillate back and forth through the charge detection cylinder between the first and second ion mirrors with a duty cycle, corresponding to a ratio of time spent by the ion passing through the charge detection cylinder and total time spent traversing a combination of the first and second ion mirrors and the charge detection cylinder during one complete oscillation cycle, of approximately 50%.
Abstract: An electrostatic linear ion trap (ELIT) array includes multiple elongated charge detection cylinders arranged end-to-end and each defining an axial passageway extending centrally therethrough, a plurality of ion mirror structures each defining a pair of axially aligned cavities and an axial passageway extending centrally therethrough, wherein a different ion mirror structure is disposed between opposing ends of each cylinder, and front and rear ion mirrors each defining at least one cavity and an axial passageway extending centrally therethrough, the front ion mirror positioned at one end of the arrangement of charge detection cylinders and the rear ion mirror positioned at an opposite end of the arrangement of charge detection cylinders, wherein the axial passageways of the charge detection cylinders, the ion mirror structures, the front ion mirror and the rear ion mirror are coaxial to define a longitudinal axis passing centrally through the ELIT array.
Abstract: A system for trapping ions for measurement thereof may include an electrostatic linear ion trap (ELIT), a source of ions to supply ions to the ELIT, a processor operatively coupled to ELIT, and a memory having instructions stored therein executable by the processor to produce at least one control signal to open the ELIT to allow ions supplied by the source of ions to enter the ELIT, determine an ion inlet frequency corresponding to a frequency of ions flowing from the source of ions into the open ELIT, generate or receive a target ion charge value, determine an optimum threshold value as a function of the target ion charge value and the determined ion inlet frequency, and produce at least one control signal to close the ELIT when a charge of an ion within the ELIT exceeds the optimum threshold value to thereby trap the ion in the ELIT.
Abstract: Technologies are disclosed herein for running a long-term on-demand service for executing actively-secure computations. A function circuit may be represented as a stream of buckets, in which each bucket represents a logical AND gate. A pool having a plurality of garbled AND gates is generated. Garbled AND gates are randomly selected from the pool for placement in one of the buckets. An output for the bucket is determined by an evaluation of the selected garbled AND gates. The output represents an execution of the logical AND gate. The determined output is applied as a parameter in a secure protocol.
Abstract: A multi-chromophore virus particle is constructed by covalent binding of chromophores and provides super-radiant behavior. A virus-enabled targeted vector is provided for imaging with qualitatively different optical emission properties from state-of-the-art agents. Bright emission is obtained through quantum coherence, which in turn is facilitated by the symmetry of the virus shell. In an exemplary embodiment the targeted vector is used in laser-guided surgery, specifically for the treatment of in brain cancer.
