The Near-Ring of Affine Transformations [PDF]
Proceedings of the American Mathematical Society, 1956 where a is variable in V, A is fixed in V, and T is a linear transformation of V. The affine transformation is nonsingular if and only if T is nonsingular. A few familiar facts [1 ] are: 1. The nonsingular affine transformations form the "affine group" under iteration. 2. The translations, i.e.

nD Quasi-Affine Transformations [PDF]
, 2016 A Quasi-Affine Transformation QAT is a transformation on $$\mathbb Z^n$$ which corresponds to the composition of a rational affine transformation and an integer part function. The aim of this paper is twofold. Firstly, it brings new insight into the periodic structures involved by a QAT. Secondly, some new results in nD are presented specifically about

FEBS Letters, EarlyView.Phytohormone brassinosteroid‐induced gene regulation by the transcription factor BIL1/BZR1 involves redox‐dependent DNA‐binding alternation and interaction with the transcription factor PIF4. The reduced BIL1/BZR1 dimer binds preferred cis‐elements, while oxidation alters its oligomerization state and disrupts DNA‐binding ability.

, 2007 We perform extensive simulations of a 2D LJ glass subjected to quasi-static shear deformation at T=0. We analyze the distribution of non-affine displacements in terms of contributions of plastic, irreversible events, and elastic, reversible motions. From

Structural dynamics of the plant hormone receptor ETR1 in a native‐like membrane environment
FEBS Letters, EarlyView.The present study unveils the structural and signaling dynamics of ETR1, a key plant ethylene receptor. Using an optimized nanodisc system and solution NMR, we captured full‐length ETR1 in a native‐like membrane environment. Our findings reveal dynamic domain uncoupling and Cu(I)‐induced rigidification, providing the first evidence of metal‐triggered ...

, 2009 We show that stochastically continuous, time-homogeneous affine processes on the canonical state space $\Rplus^m \times \RR^n$ are always regular. In the paper of \citet{Duffie2003} regularity was used as a crucial basic assumption.

FEBS Letters, EarlyView.Mutations in the C9orf72 gene represent the most common genetic cause of amyotrophic lateral sclerosis (ALS), a fatal neurodegenerative disease. Using patient‐derived neurons and C. elegans models, we find that the nucleoporin Nup107 is dysregulated in C9orf72‐associated ALS. Conversely, reducing Nup107 levels mitigates disease‐related changes.

Affine Shape Comparison using Different Distances
JOIV: International Journal on Informatics Visualization, 2020 In this work, we propose to compare affine shape using Hausdorff distance (HD), Dynamic Time Warping (DTW), Frechet (DF), and Earth Mover distance (EMD).

Confinement-induced columnar crystals of ellipses
Physical Review Research, 2021 Densest-packed structures of identical ellipses within a parallel strip have been obtained through Monte Carlo simulations and analytic derivations. Each of such structures is an affine transformation of a particular densest-packed structure of identical

Fourier analysis on the affine group, quantization and noncompact Connes geometries
, 2008 We find the Stratonovich-Weyl quantizer for the nonunimodular affine group of the line. A noncommutative product of functions on the half-plane, underlying a noncompact spectral triple in the sense of Connes, is obtained from it. The corresponding Wigner
