Spectral Properties of Clipping Noise

open access: yesMathematics, 2021
One serious disadvantage of any multicarrier-modulation technique such as orthogonal frequency division multiplexing (OFDM) is its high peak-to-average-power ratio (PAPR) which might lead to signal clipping in several scenarios.

Optimal Insurance for a Minimal Expected Retention: The Case of an Ambiguity-Seeking Insurer

open access: yesRisks, 2016
In the classical expected utility framework, a problem of optimal insurance design with a premium constraint is equivalent to a problem of optimal insurance design with a minimum expected retention constraint.

Transmission ratio distortion detection by neutral genetic markers in the Pura Raza Española horse breed

open access: yesAnimal, 2023
Transmission Ratio Distortion (TRD) is a genetic phenomenon widely demonstrated in several livestock species, but barely in equine species. The TRD occurs when certain genotypes are over- or under-represented in the offspring of a particular mating and ...

The Entropy Gain of Linear Systems and Some of Its Implications

open access: yesEntropy, 2021
We study the increase in per-sample differential entropy rate of random sequences and processes after being passed through a non minimum-phase (NMP) discrete-time, linear time-invariant (LTI) filter G.
