Impact of Advanced Load-Frequency Control on Optimal Size of Battery Energy Storage in Islanded Microgrid System

Energies, 2021
The application of battery energy storage (BES) in microgrid systems has attracted much attention in recent years. It is because the BES is able to store excess power and discharge its power when needed.

SPADE: A Deep Learning Framework for Spatial Mapping and Quantitative Cell–Cell Interaction Inference

Advanced Science, EarlyView.
SPADE integrates spatial transcriptomics with single‐cell RNA sequencing by using cell–cell communications (CCC) as a guide for spatial mapping. It improves cell‐type localization, enhances sparse gene‐expression signals, and reveals CCC programs at single‐spot resolution.

Arthroscopic Repair of the Anterior Root of the Lateral Meniscus Using Knotless All‐Suture Anchors

Arthroscopy Techniques, EarlyView.
Abstract Anterior root tears of the lateral meniscus are uncommon but can significantly disrupt knee biomechanics by increasing contact pressures and accelerating cartilage degeneration if left untreated. This article describes an arthroscopic technique for repair of the anterior root of the lateral meniscus using all‐suture anchors.

The Hybrid Reversible Suture‐Gripping Technique: A Modified Approach for Continuous Meniscal Suturing

Arthroscopy Techniques, EarlyView.
Abstract The suture‐gripping technique (SGT), which uses a suture shuttle, enables unrestricted gripping, accurate needle insertion from inside the joint, and flexible withdrawal of the suture from outside the joint. We considered the possibility of using a continuous suturing technique with this method, and thus, we describe a modified approach, the ...
