Linear Cryptanalysis of Reduced-Round Simon Using Super Rounds
Cryptography, 2020 We present attacks on 21-rounds of Simon 32/64, 21-rounds of Simon 48/96, 25-rounds of Simon 64/128, 35-rounds of Simon 96/144 and 43-rounds of Simon 128/256, often with direct recovery of the full master key without repeating the attack over multiple ...

Topological groups with invariant linear spans [PDF]
Revista Matemática Complutense, 2021 Given a topological group $G$ that can be embedded as a topological subgroup into some topological vector space (over the field of reals) we say that $G$ has invariant linear span if all linear spans of $G$ under arbitrary embeddings into topological vector spaces are isomorphic as topological vector spaces. For an arbitrary set $A$ let $\mathbb{Z}^{(A)

Partly-Pseudo-Linear Cryptanalysis of Reduced-Round Speck
Cryptography, 2020 We apply McKay’s pseudo-linear approximation of addition modular 2n to lightweight ARX block ciphers with large words, specifically the Speck family. We demonstrate that a pseudo-linear approximation can be combined with a linear approximation using the ...

Improving trajectory calculations by FLEXPART 10.4+ using single-image super-resolution [PDF]
Geoscientific Model Development, 2023 Lagrangian trajectory or particle dispersion models as well as semi-Lagrangian advection schemes require meteorological data such as wind, temperature and geopotential at the exact spatiotemporal locations of the particles that move independently from a ...

Linear verification for spanning trees [PDF]
Combinatorica, 1984 The paper deals with the following special problem: (Q) Given an n- element set \(E=(e_ 1,...,e_ n)\), and a list of m subsets of \(\{\) 1,...,n\(\}\), \(L=(S_ 1,...,S_ m)\). Find the maxima \(M_ i=\max_{j\in S_ i}e_ j,\) \(i=1,...,m\). For the solution of the problem an algorithm is proposed which finds all maxima in linear time when only the total ...

Variable Span Multistep Straightening Process for Long/Extra-Long Linear Guideways
IEEE Access, 2019 This paper presents a variable span multistep straightening process (VSMSP) to improve straightening accuracy and reduce the number of straightening steps for the multistep straightening of long linear guideways.

(Co)variance components and genetics parameter estimation for linear traits in Holstein cattle in Indonesia: traits related to foot/leg and udder [PDF]
Archives Animal Breeding, 2018 The availability of (co)variance components and genetics parameter estimates for traits included in a selection program is crucial since the estimated breeding values of the selected traits are computed based on the available (co)variance components and ...

The Linear Span of Uniform Matrix Product States
Symmetry, Integrability and Geometry: Methods and Applications, 2022 The variety of uniform matrix product states arises both in algebraic geometry as a natural generalization of the Veronese variety, and in quantum many-body physics as a model for a translation-invariant system of sites placed on a ring. Using methods from linear algebra, representation theory, and invariant theory of matrices, we study the linear span

Linear Decrease in Athletic Performance During the Human Life Span
Frontiers in Physiology, 2018 Master athletes maintain high physical activity levels and have better health than age-matched non-athletes. World records show accelerated declines after age 70 in swimming, long-distance running and sprint performance.
