Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Japan has one of the highest dialysis prevalence rates worldwide and a shrinking, aging population. Whether dialysis burden has entered a sustained post‐peak phase or whether recent declines partly reflect pandemic‐related disruptions remains uncertain.

Approximation Algorithms for the Submodular Load Balancing with Submodular Penalties
Mathematics, 2020 In this paper, we study the submodular load balancing problem with submodular penalties. The objective of this problem is to balance the load among sets, while some elements can be rejected by paying some penalties. Officially, given an element set V, we

Rounding in ¿-approximation algorithms
2006 Symposium on Communications and Vehicular Technology, 2006 A common approach to deal with NP-hard problems is to deploy polynomial-time ϵ-approximation algorithms. These algorithms often resort to rounding and scaling to guarantee a solution that is within a factor (1 + isin) of the optimal solution. Usually, researchers either only round up or only down.

Improved approximation algorithms for degree-bounded network design problems with node connectivity requirements [PDF]
, 2014 We consider degree bounded network design problems with element and vertex connectivity requirements. In the degree bounded Survivable Network Design (SNDP) problem, the input is an undirected graph G = (V, E) with weights w(e) on the edges and degree ...

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Introduction Peritoneal dialysis (PD) is an established home‐based kidney replacement therapy (KRT), but its uptake remains low in Japan. We evaluated whether individualized education in a dedicated outpatient clinic was associated with the initiation of PD.

Approximating a Minimum Dominating Set by Purification
AlgorithmsA dominating set of a graph is a subset of vertices such that every vertex not in the subset has at least one neighbor within the subset. The corresponding optimization problem is known to be NP-hard.
