    Abstract: A system and method for detecting Trojans and other intermittent severe defects in a digital circuit design. A simulation of the digital circuit design results in a value change dump file, which is compiled to form a value change summary file containing counts of the numbers of value changes for the signals in the digital circuit design. A discriminative neural network analyzes the value change summary file to determine whether an intermittent severe defect is present. A corpus of digital circuit designs, with and without intermittent severe defects, is used to train the discriminative neural network. The training process may involve dimensionality reduction of the data, enlargement of the data set, and data compression using an autoencoder.

    Abstract: An optical receiver may include a unitary transformation operator to receive an n-symbol optical codeword associated with a codebook, and to perform a unitary transformation on the received optical codeword to generate a transformed optical codeword, where the unitary transformation is based on the codebook. The optical receiver may further include n optical detectors, where a particular one of the n optical detectors is to detect a particular optical symbol of the transformed optical codeword, and to determine whether the particular optical symbol corresponds to a first optical symbol or a second optical symbol. The optical receiver may also include a decoder to construct a codeword based on the determinations, and to decode the constructed codeword into a message using the codebook. The optical receiver may attain superadditive capacity, and, with an optimal code, may attain the Holevo limit to reliable communication data rates.

    Abstract: A sensing system including in-ground sensors not requiring battery power. A thermoelectric generator sensor rod includes an upper thermal contact and a lower thermal contact at or near its two ends. When the thermoelectric generator sensor rod is buried in the ground with one end buried more deeply than the other, a temperature gradient in the soil produces a temperature difference between the upper thermal contact and the lower thermal contact. The upper thermal contact and the lower thermal contact are thermally connected to a thermoelectric generator, e.g., by heat pipes or thermally conductive rods. Electrical power generated by the thermoelectric generator powers sensors for monitoring conditions in the ground, and circuitry for transmitting sensor data to a central data processing system.
