The need for better control of secondary hyperparathyroidism [PDF]

Nephrology Dialysis Transplantation, 2004
Secondary hyperparathyroidism (SHPT), a frequent complication of chronic kidney disease, develops in response to an imbalance in the serum levels of calcium, phosphorus and vitamin D as a result of altered metabolism. Raised serum levels of parathyroid hormone (PTH) and calcium-phosphorus product have a major effect on morbidity and mortality in ...

Secondary Switched Control With no Communications for Islanded Microgrids [PDF]

IEEE Transactions on Industrial Electronics, 2017
Flexibility and reliability of AC microgrids are enhanced by reducing the dependence on communications in multi-layer hierarchical control. In this sense, this paper presents a secondary control with no communications for islanded microgrids. It is based on a control scheme that switches between two configurations according to a time-dependent protocol.

Guidelines for Pediatric Radiotherapy Simulation: A Report From the Children's Oncology Group Radiation Oncology Discipline

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric radiation therapy presents unique challenges compared to adult treatments, including those of immobilization, potential need for sedation, and the critical importance of accurate, reproducible positioning. Additionally, heightened attention to imaging doses is necessary to minimize long‐term toxicity in survivors.

Multiagent Based Distributed Control with Time-Oriented SoC Balancing Method for DC Microgrid

Energies, 2020
Based on the droop control, voltage regulation at the secondary control is required to eliminate the deviation of the average voltage across the microgrid. Meanwhile, to prevent any of energy storage (ESs) from over-charging or over-discharging, State-of-
