Novel efficient deep reinforcement learning-based load frequency control for isolated microgrid

AIP Advances
This study introduces a Learning-based Load Frequency Control (LB-LFC) approach to manage the challenges posed by renewable energy’s intermittency in microgrids, which often causes load disturbances, frequency fluctuations, and higher generation costs ...

Beyond a Technocentric Transition: A Diverse Economies Perspective for Social Justice in Circular Economy Business Models

Business Strategy and the Environment, EarlyView.
ABSTRACT The circular economy, dominated by capitalocentric, technocentric, and eco‐modernist discourses, risks perpetuating systemic injustice because of its limited consideration of the social and of what is possible. In this article, we examine how social justice can be embedded into circular business models (CBMs)—key drivers of the circular ...

Transcriptomic Profiling of SLC and ABC Transporters in the Human Term Placenta

Clinical Pharmacology &Therapeutics, EarlyView.
Solute carriers (SLC) and ATP‐binding cassette (ABC) transporters are essential for placental solute exchange and fetal protection, yet their transcriptomic profiles in the human placenta remain poorly characterized. Although fetal sex influences placental development and function, its impact on transporter expression is unclear.

An Adaptive Internal Model for Load Frequency Control using Extreme Learning Machine [PDF]

, 2018
As an important part of a power system, a load frequency control has to be prepared with a better controller to ensure internal frequency stability. In this paper, an Internal Model Control (IMC) scheme for a Load Frequency Control (LFC) with an adaptive

Association between walking gait biomechanical changes after anterior cruciate ligament injury or reconstruction and the development of osteoarthritis: A systematic review

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Anterior cruciate ligament (ACL) injury and reconstruction significantly increase the risk of knee osteoarthritis (OA). Biomechanical alterations during walking are frequently suggested contributors to OA development. This systematic review aims to determine the association between walking gait biomechanical changes following ACL ...
