Determination of the Required Power Response of Inverters to Provide Fast Frequency Support in Power Systems with Low Synchronous Inertia

Energies, 2020
The decommissioning of conventional power plants and the installation of inverter-based renewable energy technologies decrease the overall power system inertia, increasing the rate of change of frequency of a system (RoCoF). These expected high values of

Hybridization of battery with pico hydel for frequency regulation of microgrids using synchronverter control

IET Renewable Power Generation, 2022
Frequency regulation of autonomous microgrids with intermittent renewables is a tedious task, which requires additional support from energy storage systems (ESS).

Scanning Parametric Sediment Echosounder as Tool for Underwater Archaeological Prospection

Archaeological Prospection, EarlyView.
ABSTRACT Underwater cultural heritage 3D prospection techniques, especially for remains that are partly buried in the ground, are only very rarely available and often can only be applied with considerable technical effort. To overcome this limitation, we evaluate a methodological adaption of widely used and available single channel parametric sediment ...

Two-Stage Stochastic Frequency-Security-Constrained Unit Commitment for Thermal-Storage Joint Frequency Regulation Under High Renewables Using Analytical Criterion and Linear Surrogates

Energies
In modern power systems, the rapid growth of renewable energy capacity, such as wind and solar photovoltaic (PV) power, has led to a decline in system equivalent inertia and primary frequency regulation margin.

Development of a nalmefene formulation suitable for a community‐use auto‐injector

British Journal of Clinical Pharmacology, EarlyView.
Aim Time to onset of reversal is critical when treating opioid‐induced respiratory depression and hypoxia. This study aimed to develop a formulation of the opioid antagonist nalmefene with an increased absorption rate and reduced time to onset of reversal following intramuscular administration. Methods Several absorption enhancers were screened in rats,

Integrating Recycling and Emission Reduction: A Business Strategy Analysis With Multi‐Objective Mixed‐Integer Linear Programming Framework for Optimising Sustainable Closed‐Loop Supply Chain Network Design

Business Strategy and the Environment, EarlyView.
ABSTRACT This research develops an integrated mixed‐integer linear programming (MILP) model for closed‐loop supply chain network design that optimises competing economic and environmental objectives including profit maximisation, supplier quality improvement and CO2 emission reduction.

Role of selenium in the pathophysiology of cardiorenal anaemia syndrome

ESC Heart Failure, Volume 12, Issue 2, Page 770-780, April 2025.
Abstract Chronic kidney disease (CKD) and cardiovascular disease (CVD) have multiple bidirectional mechanisms, and anaemia is one of the critical factors that are associated with the progression of the two disorders [referred to as cardiorenal anaemia syndrome (CRAS)].

Forecasting heart failure: Seasonal alignment of heart failure outcomes in New York

ESC Heart Failure, Volume 12, Issue 2, Page 819-831, April 2025.
Abstract Background Seasonal variations have been observed in heart failure (HF) hospitalization. Numerous explanatory mechanisms have been proposed, but no prior studies have examined potential contributors directly. Our objective was to identify specific factors that could contribute to seasonal variability using a large longitudinal dataset of HF ...

Antibody kinetics against tetanus toxoid before and after primary vaccination of foals

Equine Veterinary Journal, EarlyView.
Abstract Background Vaccination recommendations for foals against Clostridium tetani vary. Available studies assessing foal immune responses, maternal antibody interference, or individual variation often used small foal numbers. Objectives To quantify antibody responses after tetanus vaccination in foals and explore associations with passively ...

A modular and programmable electrolyte platform: Covalently anchored thermochromic hydrogels for on‐demand electrochromic devices

FlexMat, EarlyView.
Developing stable, multifunctional hydrogel electrolytes without compromising performance presents a considerable challenge in the field. In this study, we introduce a material design strategy with broad applicability to combinations of functional polymeric segments, ionic monomers, and salts.
