2020 journal article

Improving chemotherapy infusion operations through the simulation of scheduling heuristics: a case study

Health Systems, 2, 1–16.

By: R. Slocum*, H. Jones n, M. Fletcher n, B. McConnell n, T. Hodgson n, J. Taheri n, J. Wilson n

author keywords: Discrete event simulation (DES); scheduling; healthcare; chemotherapy
TL;DR: The case study examines the impact of altering the current schedule, where all patients arrive at 8:00 AM, to a schedule that assigns patients to two or three different appointment times based on the expected length of their chemotherapy infusion. (via Semantic Scholar)

A gradient descent based algorithm for ℓp minimization

European Journal of Operational Research, 283(1), 47–56.

By: S. Jiang*, S. Fang n, T. Nie* & W. Xing*

author keywords: Global optimization; Nonsmooth optimization; Nonconvex optimization; Gradient descent algorithm; KKT condition
TL;DR: A gradient-descent-based algorithm is proposed to find solutions satisfying the scaled KKT condition without invoking the nondifferentiability issue and is capable of achieving much better sparse recovery in reasonable computational time compared to state-of-the-art interior-point based algorithms.

Modeling and transportation planning for US noncombatant evacuation operations in South Korea

Journal of Defense Analytics and Logistics, 4(1), 41–69.

By: J. Kearby n, R. Winz n, T. Hodgson n, M. Kay n, R. King n & B. McConnell n

TL;DR: This work formulates a time-staged network model of the South Korean noncombatant evacuation system as a mixed integer linear program to determine an optimal flow configuration that minimizes the time required to complete an evacuation. (via Semantic Scholar)

Investigation of multiphasic 3D-bioplotted scaffolds for site-specific chondrogenic and osteogenic differentiation of human adipose-derived stem cells for osteochondral tissue engineering applications


By: L. Mellor n, R. Nordberg n, P. Huebner n, M. Mohiti-Asli n, M. Taylor n, W. Efird*, J. Oxford*, J. Spang*, R. Shirwaiker n, E. Loboa*

author keywords: 3D-printing; chondrogenic differentiation; human adipose derived stem cells; osteochondral; osteogenic differentiation
MeSH headings : Adipose Tissue / metabolism; Biocompatible Materials / chemistry; Bone and Bones; Calcium Phosphates / chemistry; Calcium Phosphates / metabolism; Cartilage, Articular / metabolism; Cell Differentiation; Cells, Cultured; Chondrogenesis / physiology; Collagen Type I / genetics; Collagen Type I / metabolism; Extracellular Matrix / chemistry; Extracellular Matrix / metabolism; Humans; Mesenchymal Stem Cells / cytology; Mesenchymal Stem Cells / metabolism; Osteogenesis / physiology; Polyesters / chemistry; Polyesters / metabolism; Printing, Three-Dimensional; Tissue Engineering; Tissue Scaffolds / chemistry
TL;DR: A scaffold that would induce site‐specific osteogenic and chondrogenic differentiation of human adipose‐derived stem cells (hASC) to generate a full osteochondral implant is created and holds great promise as cartilage morbidity is minimized since autologous cartilage harvest is not required.
