Stochastic disturbances to deterministic systems
, 1990 Stochastic disturbances affecting deterministic partial differential equations both as inhomogeneous terms and as side conditions are investigated. In particular, a random process with piecewise constant sample functions is introduced for modeling such ...

Hierarchical Physical‐Cyber Encryption via Metasurface‐Encoded Holographic Keys
Advanced Science, EarlyView.ABSTRACT Physical‐layer encryption based on metasurfaces has emerged as a promising alternative to conventional algorithmic cryptography by embedding security into physical processes. However, most existing metasurface‐based encryption schemes operate within single‐stage or static frameworks, where correct physical illumination directly reveals the ...

Integration of Reconfigurable p‐Bit and 1R Crossbar Array for Memristive Probabilistic Computing
Advanced Science, EarlyView.A memristive probabilistic computing system is demonstrated by integrating stochastic p‐bits based on volatile memristors with a 1R crossbar array encoding interaction weights. The system performs weighted‐sum operations across the array and updates p‐bits iteratively.

Sub-vector Efficiency analysis in Chance Constrained Stochastic DEA: An application to irrigation water use in the Krishna river basin, India [PDF]
All deviations from the frontier is inefficiency in deterministic DEA (DDEA); thus making the DDEA unable to accommodate the measurement and specification errors.
