In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS
FEBS Letters, EarlyView.We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Improving complexity of Karmarkar's approach for linear programming
Journal of Numerical Analysis and Approximation Theory, 2014 In this paper, we are interested in the performance of Karmarkar's projective algorithm for linear programming. Based on the work of Schrijver, we offer a new displacement step better than Schrijver's one which led to a moderate improvement in the ...

AN INTERIOR-POINT METHOD FOR MPECs BASED ON STRICTLY FEASIBLE RELAXATIONS. [PDF]
, 2004 An interior-point method for solving mathematical programs with equilibrium constraints (MPECs) is proposed. At each iteration of the algorithm, a single primaldual step is computed from each subproblem of a sequence.

Cell wall target fragment discovery using a low‐cost, minimal fragment library
FEBS 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 new full-NT step interior-point method for circular cone optimization
Croatian Operational Research Review, 2019 We present a full step interior-point algorithm for circular coneoptimization using Euclidean Jordan algebras. The specificity of ourmethod is to use a transformation similar to that introduced byDarvay and Tak\'acs for the centering equations of the ...

Modified Interior-Point Method for Large-and-Sparse Low-Rank Semidefinite Programs
, 2017 Semidefinite programs (SDPs) are powerful theoretical tools that have been studied for over two decades, but their practical use remains limited due to computational difficulties in solving large-scale, realistic-sized problems.
