Deep binarized photonic reservoir computing for ultrafast multimedia signal processing

Abstract We present a deep photonic neural network architecture based on ultrafast binary optical modulation using a digital micromirror device (DMD), optical scattering in a random medium, high-speed photodetection with a CMOS sensor, and a time-multiplexed multilayer structure....

Mechanisms of non-monotonic signal dependence on repetition rate in high-repetition-rate nanosecond LIBS

High-repetition-rate nanosecond laser-induced breakdown spectroscopy (LIBS) offers advantages such as small ablation crater and high signal-to-noise ratio. To investigate the non-monotonic influence of repetition rate on signal intensity, we conducted high-repetition-rate LIBS ex...

Optimal Execution on Uniswap v2/v3 under Transient Price Impact

We study the optimal liquidation of a large position on Uniswap v2 and Uniswap v3 in discrete time. The instantaneous price impact is derived from the AMM pricing rule. Transient impact is modelled to capture either exponential or approximately power-law decay, together with a pe...

Inlining as a Space Optimization: A Simple Time- and Space-Invariant Implementation of the Weak Lambda-Calculus

We propose an implementation model for the evaluation of the weak λ-calculus, which is invariant for both time and space complexity, in both call-by-name and call-by-value strategies. In other words, this model provides an implementation of any weak call-by-name or weak call-by-v...

Toward Climate-Responsive Ocean–Terrestrial Biorefineries: Integrating Algae and Agricultural Residues for Circular Bioeconomies

Abstract This paper evaluates climate-responsive biorefineries that integrate pelagic Sargassum with agricultural residues to advance circular bioeconomies. Building on scientific priorities emphasized at the 2025 One Ocean Science Congress and emerging policy directions from the...

Analysis of Injector Staging Patterns With Comparisons of Limit Cycle Amplitudes Over a Full Domain of Operation

Abstract Injector staging has recently been demonstrated to control thermoacoustic instabilities in an annular combustor, but its effects were investigated at a single operating point. This work extends this concept to a wide operating domain comprising a range of thermal powers...
