Projective algorithms for solving complementarity problems

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2002
We present robust projective algorithms of the von Neumann type for the linear complementarity problem and for the generalized linear complementarity problem.

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane

open access: yesFEBS Letters, EarlyView.
Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

open access: yesFEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Three Tales of Change

open access: yesSAGE Open, 2016
When could it be safe to report ordinal scores instead of linear measures? In this study, preschool gains measured with ordinal scores were compared with residualized gain scores, as well as Rasch model measures of linear change (logits) to clarify ...

Algebraic multigrid preconditioners for two-phase flow in porous media with phase transitions

open access: yes, 2018

On degeneracy in linear complementarity problems

open access: yesDiscrete Applied Mathematics, 1985
This paper presents a method for handling degeneracy in linear complementarity problems. The method is based on the sequential (variable-dimension) version of Lemke's algorithm. Curiously, the paper makes no mention of other publications pertaining to degeneracy handling in Lemke's method or any other.

AAA+ protein unfoldases—the Moirai of the proteome

open access: yesFEBS Letters, EarlyView.
AAA+ unfoldases are essential molecular motors that power protein degradation and disaggregation. This review integrates recent cryo‐electron microscopy (cryo‐EM) structures and single‐molecule biophysical data to reconcile competing models of substrate translocation.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

open access: yesFEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Transcriptional network analysis of PTEN‐protein‐deficient prostate tumors reveals robust stromal reprogramming and signs of senescent paracrine communication

open access: yesMolecular Oncology, EarlyView.
Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...

A Preconditioned Multisplitting and Schwarz Method for Linear Complementarity Problem

open access: yesJournal of Applied Mathematics, 2014
The preconditioner presented by Hadjidimos et al. (2003) can improve on the convergence rate of the classical iterative methods to solve linear systems.
