Abstract: A bit interleaver, a bit-interleaved coded modulation (BICM) device and a bit interleaving method are disclosed herein. The bit interleaver includes a first memory, a processor, and a second memory. The first memory stores a low-density parity check (LDPC) codeword having a length of 64800 and a code rate of 4/15. The processor generates an interleaved codeword by interleaving the LDPC codeword on a bit group basis. The size of the bit group corresponds to a parallel factor of the LDPC codeword. The second memory provides the interleaved codeword to a modulator for 256-symbol mapping.

Abstract: Inversion techniques are provided for imaging subsurface regions from geophysical data sets. The inversion techniques provide a geophysical data set containing data measured from a subsurface region to an objective function. These techniques further optimize the objective function to invert for an implicitly represented geologic structure of the subsurface region and at least one geophysical parameter of the subsurface region. In addition, the inversion techniques use a computer system to present results produced by the objective function optimization.

Abstract: A container corresponding to executable code may be received. The container may be executed in a secure computation environment by performing one or more operations specified by the executable code of the container.

Abstract: An integrator in a duty-cycle adjustment circuit has an adjustable charging current provided by a switched current-source array in response to configuration signals from the calibration logic. The integrator's ramp voltage is compared to a threshold voltage by a comparator to generate an output clock. A tunable voltage reference generates a reference voltage that can be tuned by configuration signals from the calibration logic. The reference voltage is divided by a tunable voltage divider, which selects different fractions of the reference voltage for use as the threshold voltage. During calibration, calibration logic repeatedly raises the reference voltage or reduces the charging current from the switched current-source array until a peak voltage of the ramp voltage equals the reference voltage, when a zero duty onset detector detects that the output clock has stopped pulsing. The configuration signals at the zero duty onset condition are stored and used for normal operation.

The processor generates the LDPC codeword by performing accumulation with respect to the second memory using information bits. The accumulation is performed at parity bit addresses that are updated using a sequence corresponding to a parity check matrix (PCM).

Abstract: A chip-scale ultrasensitive ring laser gyroscope that utilizes the physics of exceptional points. By exploiting the properties of such non-Hermitian degeneracies, the rotation-induced frequency splitting becomes proportional to the square root of the gyration speed (?1/2), thus enhancing the sensitivity to low angular rotations by orders of magnitudes. At its maximum sensitivity limit, the measurable spectral splitting is independent of the radius of the cavity rings involved. Binary and ternary systems and associated methods are described.
