Dexamethasone for Chemotherapy‐Induced Nausea and Vomiting Prevention in Pediatric Patients: International Consensus

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background An international Delphi panel of experts developed consensus statements to delineate the circumstances where the risks of dexamethasone as an antiemetic do and do not outweigh its benefits. Procedure Experts in supportive care of pediatric patients were invited to participate.

Enhanced Three-Phase Inverter Control: Robust Sliding Mode Control with Washout Filter for Low Harmonics

Energies
This paper presents a robust control strategy for three-phase inverters that combines Sliding Mode Control with a Washout Filter (SMC-w) to achieve low harmonic distortion and high dynamic stability. The proposed approach addresses the critical challenge

An Improved Model Predictive Fast Frequency Control for Power System Stability Against Unknown Time-Delay Switch Attack

IEEE Access, 2022
A modern power grid is a cyber-physical system, which are vulnerable to cyber attacks. A recently found attack, the time-delay switch attack (TDSA), is made by inserting time delays into communication channels. A TDSA can be highly destructive to a power

Frequency-Power Control of VSWTG for Improved Frequency Regulation

, 2020
With increasing wind energy penetration and impending grid codes, it is important to enable wind-based power plants to provide sensitive frequency response in grids that may experience irregular frequency fluctuations with noise induced. Transient low-frequency deviations are handled by inertial control, while active power frequency response controller

Simulation Analysis of Frequency Regulation

IOP Conference Series: Earth and Environmental Science, 2019
Abstract Frequency is one of the most important parameters reflecting the operation quality of the system. When the system is in steady-state operation, the frequency of the generator in the system is equal under steady-state operation. Because the load is changing at any time, this kind of balance is dynamic.

Clinical Insights Into Hypercalcemia of Malignancy in Childhood

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Hypercalcemia of malignancy (HCM) is a rare but life‐threatening metabolic emergency in children that occurs in less than 1% of pediatric cancer cases, with a reported incidence ranging from 0.4% to 1.0% across different studies. While it is observed in 10%–20% of adult malignancies, pediatric HCM remains relatively uncommon.

Cash Tender Offers for Shares—A Reply to Chairman Cohen [PDF]

, 1967
In the past few years, the corporate takeover device of the cash tender offer has grown in frequency, and thus in importance. Concomitantly, legislation designed to sweep this relatively unregulated method of acquiring corporate control into the ambit of
