Mechanism Design via Dantzig-Wolfe Decomposition [PDF]
, 2016 In random allocation rules, typically first an optimal fractional point is calculated via solving a linear program. The calculated point represents a fractional assignment of objects or more generally packages of objects to agents.

Algorithm for Solving Linear Fractional Programming
Journal of Physics: Conference Series, 2021 Abstract To solve the Linear Fractional Programming system, the Charnes-Cooper Transformation is used to split the original objective function to an equivalent, simplified linear programming system. To prove the congruence of two systems, the feasibility and optimality of the linear fractional program maximizes or minimizes a ratio of ...

A Proposal to the Solution of Multiobjective Linear Fractional Programming Problem
Abstract and Applied Analysis, 2013 We have proposed a new solution to the Multiobjective Linear Fractional Programming Problem (MOLFPP). The proposed solution is based on a theorem that deals with nonlinear fractional programming with single objective function and studied in the work by ...

Structural biology of ferritin nanocages
FEBS 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 ...

FEBS Letters, EarlyView.In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Tau acetylation at K331 has limited impact on tau pathology in vivo
FEBS Letters, EarlyView.We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

A linear fractional bilevel programming problem with multichoice parameters
Croatian Operational Research Review, 2017 A bilevel programming problem (BLPP) is a hierarchical optimization problem where the constraint region of the upper level is implicitly determined by the lower level optimization problem.
