Spatial signature for secure MISO‐OFDM systems [PDF]
Electronics Letters, 2018 Physical layer security is a promising approach to establish secure communications based on the characteristics of wireless channels. A spatial signature based secure multiple‐input single‐output (MISO) orthogonal frequency division multiplexing (OFDM) system is proposed to disrupt the reception of a passive eavesdropper by holding two practically ...

Signatures of Quantum Mechanics in Chaotic Systems [PDF]
Entropy, 2019 We examine the quantum-classical correspondence from a classical perspective by discussing the potential for chaotic systems to support behaviors normally associated with quantum mechanical systems. Our main analytical tool is a chaotic system’s set of cupolets, which are highly-accurate stabilizations of its unstable periodic orbits. Our discussion is

IET Biometrics, 2022 Signing a document or a cheque by hand or using a stored image‐based signature is known to be a valid method for authentication and authorisation by the signer. However, signature forging has advanced to replicate exactly how a signature looks, which can

Molecular “omic” signatures in systemic sclerosis
European Journal of Rheumatology, 2020 Systemic sclerosis (SSc) is a connective tissue disorder characterized by immunologic, vascular, and extracellular matrix abnormalities. Variation in the proportion and/or timing of activation in the deregulated molecular pathways that underlie SSc may explain the observed clinical heterogeneity in terms of disease phenotype and treatment response.

A New Approach to Compute System Reliability with Three-Serially Linked Modules
Mathematics, 2022 The efficiency of a bridge system and a 2-out-of-4:G system has been evaluated in the proposed work. The technique for evaluating the system’s reliability and signature reliability of different models has been employed in this work.

Signature Limits in Mindreading Systems [PDF]
Cognitive Science, 2014 AbstractRecent evidence that young children seem to both understand false belief in one sense, but not in another, has led to two‐systems theorizing about mindreading. By analyzing the most detailed two‐systems approach in studying social cognition—the theory of mindreading defended by Ian Apperly and Stephen Butterfill—I argue that that even when ...
