Methods and compositions for probe amplification to detect, identify, quantitate, and / or analyze a targeted nucleic acid sequence. After hybridization between a probe and the targeted nucleic acid, the probe is modified to distinguish hybridized probe from unhybridized probe. Thereafter, the probe is amplified. Moreover, in specific embodiments, the present invention involves a chimeric probe that is particularly effective when the targeted nucleic acid sequence is short and / or has a relatively low concentration, such as with an miRNA molecule.

The present invention provides modified primers for use in the amplification of a nucleic acid sequence. Amplifications carried out using the modified primers result in less template-independent non-specific product (primer dimer) compared to amplifications carried out using unmodified primers.

Improved algorithm techniques may be used for superior operation of haptic-based systems. An eigensystem may be used to determine for a given spatial distribution of control points with specified output the set of wave phases that are the most efficiently realizable. Reconstructing a modulated pressure field may use emitters firing at different frequencies. An acoustic phased-array device uses a comprehensive reflexive simulation technique. There may be an exchange of information between the users and the transducer control processors having the ability to use that information for optimal haptic generation shadows and the like. Applying mid-air haptic sensations to objects of arbitrary 3D geometry requires that sensation of the object on the user's hand is as close as possible to a realistic depiction of that object. Ultrasonic haptics with multiple and / or large aperture arrays have high-frequency update rates required by the spatio-temporal modulation. More efficient haptic systems require the prevention of a channel of audio unintentionally encoding phase information that may distort its perception.

A quantum-state-refresh module of a memory system is configured to detect an error in an entangled qubit state stored therein by performing a redundant measurement of syndrome values corresponding to a quantum stabilizer code, with the redundant measurement being based on a block error-correction code. The quantum-state-refresh module includes a plurality of measurement sub-modules, each configured to measure a respective syndrome value or a respective parity value corresponding to the entangled qubit state. The total number of the measurement sub-modules is smaller than the codeword length of the block error-correction code, and the initial approximation of the punctured syndrome values is replaced in the decoding process by erasure values. With the block error-correction code appropriately constructed for the use of erasure values, the quantum-state-refresh module is advantageously capable of providing reliable error detection with fewer quantum gates than that used for the full-length measurement of the codeword.

A method for digital preemphasizer high fidelity reconstruction of an original pulse code modulation (PCM) serial stream binary data signal which has suffered degradation of fidelity, and consequent increase in bit-error-rate, during transmission on a single channel from a transmitter to a receiver. Prior to transmission, amplitude encoded digital pre-emphasis of each bit of the original binary data signal to be transmitted mitigates or remedies the signal degrading frequency dependent losses concomitant with the signal transfer network characteristics of the fixed transmission line. Subsequently, the amplitude encoded signal is transmitted to the receiver connected to the other end of the fixed transmission line. Compared to a conventional transmitter, transmision line, and receiver system, the end result of amplitude encoded pre-emphasis is superior reconstructed fidelity and quality of the PCM waveform, i.e. lower bit-error-rate, at the output of the receiver for the same length of transmission line.
