This paper studies a redundant transmission-based defense strategy against reverse attacks on remote state estimation. Firstly, a game-theoretic framework is developed, allowing both the adversary and defender to select multiple channels for attacking and transmitting data. Secondly, within the proposed framework, a zero-sum game, a general-sum game, and a Bayesian game are formulated depending on the defender's knowledge of the attacker's cost. Finally, the Nash and Bayesian Nash equilibria of the three games are analyzed and computed to identify the optimal strategies for both the attacker and defender. Numerical simulations are conducted to demonstrate the proposed approach.

A new gated ring oscillator time amplifier (GRO-TA) featuring a well-defined linear programmable gain, a virtually unlimited range of gain, the ability to amplify a sub-pico-second time input, fast amplification, low power consumption, and full compatibility with technology is proposed. The time amplifier is utilized in development of an all-digital time integrator. Both the time amplifier and time integrator are designed in a TSMC 130 nm 1.2 V CMOS technology and analyzed using Spectre with BSIM3 device models. Simulation results are presented.

This paper proposes an all-digital time integrator consisting of a 9-stage bi-directional gated ring oscillator (BD-GRO) and a 16-stage bi-directional shift-register (BDSR) up-down counter. The BDGRO performs time integration whereas the BDSR counter digitizes the result of time integration. The time integrator features a low resolution of the per-stage-delay of the BDGRO, low power consumption, inherent dynamic element matching, self-digitization, and full technology compatibility. The time integrator is designed in a TSMC 130 nm 1.2 V CMOS technology and analyzed using Spectre with BSIM3 device models. The performance of the time integrator is assessed using simulation results.

Many applications in photoacoustic microscopy (PAM) require laser pulses at multiple wavelengths. High repetition rate multi-wavelength lasers have been demonstrated using nonlinear fiber optics, which produce a wide wavelength range but tend to suffer from low pulse energy (e.g. 100 nJ). This paper presents our preliminary investigation into multimode fibers as a path to achieve higher output laser pulse energy for multi-spectral PAM. Laser pulses from a 532 nm pulsed Nd:YAG laser are coupled into a large mode area (LMA) fiber that supports six spatial modes at 532 nm. Phase-matched four-wave mixing (FWM) between fiber modes produces a broad continuum extending past 800 nm. The pulse energy at 550, 650, and 750 nm spectral bands is 0.84 uJ, 1.31 uJ, and 0.73 uJ, respectively. Multi-spectral imaging experiments successfully differentiate vessel phantoms containing Allura Red, methylene blue, and IR-820 dyes. These results show the potential of using intermodal FWM in a few-mode multimode fiber to achieve uJ-level pulse energies for multi-spectral PAM applications.

Since the perceptual quality of audio signals is easily to be affected by compression, transmission, noise adding, etc, it is of great significance to develop an effective audio quality assessment (AQA) method to measure end-user’s quality of experience. In this paper, we propose a full reference AQA model named Multidimensional Similarity Fusion for Audio Quality Assessment (MSF-AQA). We generalize the similarity-based image quality assessment methods for audio, then extract audio similarity features from multiple dimensions, and finally regress the multidimensional similarity features into the final quality score. The experimental results across three databases indicate that our MSF-AQA model outperforms the state-of-the-art AQA methods.
