Abstract: Systems and method for determining a topic cohesion measurement between a content item and a hyperlinked landing page are presented. In one embodiment, a plurality of content item signals is generated for the content item and a corresponding plurality of signals are generated for the hyperlinked landing page. An analysis of the corresponding signals is conducted to determine a measurement of topic cohesion, a topic cohesion score, between the content item and the hyperlinked landing page. A cohesion predictor model is trained to generate the predictive topic cohesion score between an input content item and a hyperlinked landing page. Upon a determination that the topic cohesion score is less than a predetermined threshold, remedial actions are taken regarding the hyperlink of the content item. Alternatively, positive actions may be carried out, including promoting the content item to others, associating advertisements with the content item, and the like.

Abstract: A method of security detection for a physical layer authentication system takes into account the signal-discriminating ability of an active adversary. The distance to the active adversary is estimated by an authorized transmitter based on its broadcast signal and, based on the distance estimate, the signal-to-noise ratio (SNR) of the adversary is also estimated.

Abstract: This invention provides an accurate current mirror circuit in a low voltage headroom applied to common-anode laser drivers, including a reference current detection unit, a tail current source unit, and a control unit. The reference current detection unit generates a bias voltage and a reference voltage according to a reference current from the reference current source; the tail current source unit receives the bias voltage and generate a mirror current accordingly; the control unit receives the reference voltage and an output voltage corresponding to the mirror current and carry out a feedback regulation to the bias voltage accordingly. In this invention, the reference voltage and the output voltage are locked at same level, and then the bias voltage is mirrored to generate the mirror current outputted to the laser, thus avoiding the problem of inaccurate current output caused by the offset of the control unit in the low voltage headroom.

Abstract: In a method of security detection for a physical layer authentication a transmitter transmits a first signal, which, after passing over a wireless fading channel becomes a second signal. An active adversary receives the second signal and determines a first false alarm probability based. The adversary may determine a first optimal threshold by setting the first false alarm probability less than or equal to an upper bound, and then determine a first detection probability. A receiver device also receives the second signal, extracts an object signal from it, determines a residual signal from the object signal, and a second testing statistic. The receiver may then determine a second optimal threshold and a second detection probability. Based on the first and second detection probabilities, the system may determine a probability of security authentication and thus measure the safety of the physical layer authentication system.
