Shear displacement gradient in X-ray Bragg coherent diffractive imaging
Journal of Synchrotron Radiation, 2022 Bragg coherent X-ray diffractive imaging is a cutting-edge method for recovering three-dimensional crystal structure with nanoscale resolution. Phase retrieval provides an atomic displacement parallel to the Bragg peak reciprocal lattice vector.

Tensor-based trapdoors for CVP and their application to public key cryptography [PDF]
, 1999 We propose two trapdoors for the Closest-Vector-Problem in lattices (CVP) related to the lattice tensor product.

Quantum Thetas on Noncommutative T^4 from Embeddings into Lattice
, 2007 In this paper we investigate the theta vector and quantum theta function over noncommutative T^4 from the embedding of R x Z^2. Manin has constructed the quantum theta functions from the lattice embedding into vector space (x finite group).

Vector lattice covers of ideals and bands in pre-Riesz spaces
, 2018 Pre-Riesz spaces are ordered vector spaces which can be order densely embedded into vector lattices, their so-called vector lattice covers. Given a vector lattice cover $Y$ for a pre-Riesz space $X$, we address the question how to find vector lattice ...

Atomic Operators in Vector Lattices [PDF]
Mediterranean Journal of Mathematics, 2020 AbstractIn this paper, we introduce a new class of operators on vector lattices. We say that a linear or nonlinear operator T from a vector lattice E to a vector lattice F is atomic if there exists a Boolean homomorphism $$\Phi $$ Φ from the Boolean algebra $${\mathfrak {B}}(E)$$ B ( E ) of all order projections on E to $${\mathfrak {B}}(F)$$ B ...

The projectable hull of an archimedean $ell$-group with weak unit [PDF]
Categories and General Algebraic Structures with Applications, 2017 The much-studied projectable hull of an $ell$-group $Gleq pG$ is an essential extension, so that, in the case that $G$ is archimedean with weak unit, ``$Gin {bf W}$", we have for the Yosida representation spaces a ``covering map" $YG leftarrow YpG$.

Vector lattices with a Hausdorff uo-Lebesgue topology
, 2021 We investigate the construction of a Hausdorff uo-Lebesgue topology on a vector lattice from a Hausdorff (o)-Lebesgue topology on an order dense ideal, and what the properties of the topologies thus obtained are.

Nucleon axial charge from quenched lattice QCD with domain wall fermions [PDF]
, 2003 We present a quenched lattice calculation of the nucleon isovector vector and axial-vector charges gV and gA. The chiral symmetry of domain wall fermions makes the calculation of the nucleon axial charge particularly easy since the Ward-Takahashi ...

Analysis of decreasing squared-sum of Gram–Schmidt lengths for short lattice vectors
Journal of Mathematical Cryptology, 2017 In 2015, Fukase and Kashiwabara proposed an efficient method to find a very short lattice vector. Their method has been applied to solve Darmstadt shortest vector problems of dimensions 134 to 150.
