Homomorphisms between Fuzzy Approximation Spaces Based on Residuated Lattice

Journal of Applied Mathematics, 2014
Two kinds of homomorphisms of fuzzy approximation spaces based on complete residuated lattice are proposed. The homomorphisms are structure-preserving maps in some sense.

Approximation spaces for H-operators

Involve, a Journal of Mathematics
This paper defines and establishes relations among approximation spaces of certain operators called \textit{H-operators}, which generalize the notion of self-adjoint to Banach spaces.

Identifying transcription factors controlling the basal expression of human MRP4 highlights a substantial role for Sp1

FEBS Open Bio, EarlyView.
The MRP4 transporter exports several drugs and signaling molecules. Here, we identified key promoter elements regulating basal MRP4 expression. Using reporter assays, we defined a conserved region with essential Sp1 and contributory Ets sites, which controlled basal MRP4 expression.

Molecular dynamics simulations of positively selected codons in FcγRI reveal novel biochemical binding properties

FEBS Open Bio, EarlyView.
Evolutionary analysis across 32 placental mammals identified positive selection at residues H148 and W149 in the immune receptor FcγR1. Ancestral reconstruction combined with molecular dynamics simulations reveals how these mutations may influence receptor structure and dynamics, providing insight into the evolution of antibody recognition and immune ...

Topology preserving approximation of free configuration space

, 2017
We present a simple algorithm for approximating the free configuration space of robots with low degrees of freedom (DOFs). We represent the free space as an arrangement of contact surfaces.

Refinement of amino‐acid conformation vs. difference density maps in time‐resolved serial femtosecond crystallography data analysis

FEBS Open Bio, EarlyView.
The dFoCC pipeline starts with observed DED and resting‐state coordinates, which are then used to generate a library of triggered states. Correlation analysis of the calculated DED features of each candidate vs observed DED permits quantitative evaluation of candidate structural quality.

Separation and approximation in normed linear spaces.

, 1986
This paper is basically concerned with the geometry of normed linear spaces. Approximation enters as one is concerned about approximation from discrete sets and the relation to the geometry of the space.

A note on the polynomial approximation of vertex singularities in the boundary element method in three dimensions

, 2008
We study polynomial approximations of vertex singularities of the type $r^\lambda |\log r|^\beta$ on three-dimensional surfaces. The analysis focuses on the case when $\lambda > -\frac 12$.

APPROXIMATIONS IN THE SPACE (U,π)

Demonstratio Mathematica, 1983
In this paper we introduce the notion of an approximation space as a pair (U,\(\Pi)\), where U denotes an arbitrary, non-empty set and \(\Pi\) denotes a covering of U. The elements of the covering \(\Pi\) we call elementary sets in the approximation space (U,\(\Pi)\). We also introduce the notions of upper and lower approximation of a set in the space (

RoundMi: A quantitative method to analyze mitochondrial morphology in mitotic cells

FEBS Open Bio, EarlyView.
RoundMi is a workflow for rapid analysis of mitochondrial morphology in mitotic cells. By combining adaptive preprocessing with automated segmentation and quantification, it enables accurate measurements from single focal plane images, reducing acquisition time and computational demands while remaining compatible with high‐throughput fixed and live ...
