New techniques for trail bounds and application to differential trails in Keccak

open access: yesIACR Transactions on Symmetric Cryptology, 2017
We present new techniques to efficiently scan the space of high-probability differential trails in bit-oriented ciphers. Differential trails consist in sequences of state patterns that we represent as ordered lists of basic components in order to arrange

Pragmatic Space-Time Codes for Cooperative Relaying in Block Fading Channels

open access: yesEURASIP Journal on Advances in Signal Processing, 2008
We address the problem of construction of space-time codes for cooperative communications in block fading channels. More precisely, we consider a pragmatic approach based on the concatenation of convolutional codes and BPSK/QPSK modulation to obtain ...

SMEFT deviations

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
This work is based on a bottom-up approach to the standard-model effective field theory (SMEFT), resulting in an equiprobable space of Wilson coefficients.

RSSI Probability Density Functions Comparison Using Jensen-Shannon Divergence and Pearson Distribution

open access: yesTechnologies, 2021
The performance of a free-space optical (FSO) communications link suffers from the deleterious effects of weather conditions and atmospheric turbulence. In order to better estimate the reliability and availability of an FSO link, a suitable distribution ...

An orbit determination method of spacecraft based on distribution regression

open access: yesOpen Astronomy, 2021
A new method of orbit determination (OD) is proposed: distribution regression. The paper focuses on the process of using sparse observation data to determine the orbit of the spacecraft without any prior information. The standard regression process is to

Sensitivity analysis of spacecraft in micrometeoroids and orbital debris environment based on panel method

open access: yesDefence Technology, 2023
To reduce the risk of mission failure caused by the MM/OD impact of the spacecraft, it is necessary to optimize the design of the spacecraft. Spacecraft survivability assessment is the key technology in the optimal design of spacecraft.

A View on Optimal Transport from Noncommutative Geometry

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2010
We discuss the relation between the Wasserstein distance of order 1 between probability distributions on a metric space, arising in the study of Monge-Kantorovich transport problem, and the spectral distance of noncommutative geometry.

Relativistic Schrödinger equation and probability currents for free particles

open access: yesPracì Mìžnarodnogo Geometričnogo Centru
In this work, we start from the problem of quantizing the relativistic Hamiltonian of a free massive particle (rest mass different from 0), a problem exceptionally difficult in the standard approaches to quantum mechanics.
