Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

Cutting plane methods for general integer programming [PDF]
, 1993 Integer programming (IP) problems are difficult to solve due to the integer restrictions imposed on them. A technique for solving these problems is the cutting plane method.

On the complexity of cutting-plane proofs
Discrete Applied Mathematics, 1987 As introduced by \textit{V. Chvatal} [Discrete Math. 4, 305-337 (1973; Zbl 0253.05131)] cutting planes provide a canonical way of proving that every integral solution of a given system of linear inequalities satisfies another specified inequality. In this note we make several observations on the complexity of such proofs in general and when restricted ...

Reciprocal control of viral infection and phosphoinositide dynamics
FEBS Letters, EarlyView.Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Theory and computation of sparse cutting planes [PDF]
, 2017 Cutting plane plays an important role in the theory and computation of integer programming. Nowadays, most state-of-the-art integer programming solvers tend to bias their cutting plane selection towards sparse ones, which emphasizes the significance of ...

Revista Colombiana de Estadística, 2005 Quantile regression is a nondifferentiable convex optimization problem. We compare three classical numerical methods, two of them based on linear optimization, and the cutting plane method.

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.

Integer polyhedra for program analysis [PDF]
, 2009 Polyhedra are widely used in model checking and abstract interpretation. Polyhedral analysis is effective when the relationships between variables are linear, but suffers from imprecision when it is necessary to take into account the integrality of the ...

A nontangential cutting plane algorithm
Operations Research Letters, 2002 The author examines the cutting plane algorithm for solving the Lagrangian dual problem of a convex program. This paper demonstrates that the algorithm still converges to an optimal solution when cuts are nontangential or generated by not solving the optimality or nearly so. Computational results from randomly generated linear and quadratic programming
