The Monomial Preconditioned SSOR Method for Linear Complementarity Problem

open access: yesIEEE Access, 2019
This paper aims to show that the existing preconditioned symmetric successive over-relaxation (SSOR) approach to solving the linear complementarity problem (LCP) is not valid.

Note on error bounds for linear complementarity problems involving BS-matrices

open access: yesAIMS Mathematics, 2022
Using the range for the infinity norm of inverse matrix of a strictly diagonally dominant M-matrix, some new error bounds for the linear complementarity problem are obtained when the involved matrix is a BS-matrix.

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

open access: yesFEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Combined approach to solve linear complementarity problem

open access: yesJournal of Numerical Analysis and Approximation Theory, 2016
In this paper, we present a new approach in order to solve the linear complementary problem noted (LCP). We have combined the ideas of Lemke's method and its variants taking advantage of the benefits of each approach in order to improve the convergence ...

A class of singular Ro-matrices and extensions to semidefinite linear complementarity problems [PDF]

open access: yesYugoslav Journal of Operations Research, 2013
For ARnxn and qRn, the linear complementarity problem LCP(A, q) is to determine if there is xRn such that x ≥ 0; y = Ax + q ≥ 0 and xT y = 0. Such an x is called a solution of LCP(A,q).

Cell wall target fragment discovery using a low‐cost, minimal fragment library

open access: yesFEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

A Full-Newton step infeasible-interior-point algorithm for P*(k)-horizontal linear complementarity problems [PDF]

open access: yesYugoslav Journal of Operations Research, 2015
In this paper we generalize an infeasible interior-point method for linear optimization to horizontal linear complementarity problem (HLCP). This algorithm starts from strictly feasible iterates on the central path of a perturbed problem that is

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Improved Full-Newton-Step Infeasible Interior-Point Method for Linear Complementarity Problems

open access: yesCroatian Operational Research Review, 2016
We present an Infeasible Interior-Point Method for monotone Linear Complementarity Problem (LCP) which is an improved version of the algorithm given in [13]. In the earlier version, each iteration consisted of one feasibility step and few centering steps.

Structural biology of ferritin nanocages

open access: yesFEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...
