Dynamic Improvement of DC Microgrids Using a Dual Approach Based on Virtual Inertia

Journal of Modern Power Systems and Clean Energy, 2022
In this paper, inspired by the concept of virtual inertia in alternating current (AC) systems, a virtual impedance controller is proposed for the dynamic improvement of direct current microgrids (DCMGs).

FiN‐Kiri: Fabric‐Based Inflatable Kirigami Actuator for Multimodal Soft Robots

Advanced Robotics Research, EarlyView.
This study introduces a type of inflatable fabric‐based kirigami actuator capable of performing bending motion. The actuator is utilized as soft grippers, a crawling robot and a swimming robot. The crawling robot demonstrated extraordinary motion capabilities, such as moving forward, turning and navigating a narrow tunnel.

Towards non-virtual inertia control of renewable energy for frequency regulation: Modeling, analysis and new control scheme

International Journal of Electrical Power & Energy Systems
Currently, when renewable generation participates in frequency regulation, the traditional control method is to emulate synchronous generators through virtual inertia control.

Fibrates Inhibit PLTP‐induced M2 Macrophage Infiltration and Increase the Sensitivity of Hepatocellular Carcinoma to ICIs

Advanced Science, EarlyView.
Phospholipid transfer protein(PLTP) plays a critical role in forming a complex with kinase A (AURKA) and P65. This interaction facilitates phosphorylation of P65 at Ser536, leading to the activation of the NF‐κB signaling pathway. Ultimately, this leads to the upregulation of downstream cytokines, including IL‐6, IL‐8, and CSF‐1, which promotes M2 ...

Establishment of an auxiliary virtual damping loop for the superior inertial response in the microgrid

IET Smart Grid, 2019
Low inertial microgrids in the power network are extremely sensitive toward any uncertainties. Therefore, the practise of complementing inertia virtually in microgrids has earned huge attention in recent time.

Palmitoylation‐Mediated Ubiquitination of SRPK1 Regulates Ferroptosis in High‐Fat‐Induced Erectile Dysfunction

Advanced Science, EarlyView.
Elevated exogenous palmitic acid promotes the S‐palmitoylation of SRPK1 in endothelial cells, a dynamic process governed by ZDHHC24 and APT1. This post‐translational modification strengthens the interaction between SRPK1 and the E3 ubiquitin ligase MIB1, thereby facilitating the proteasomal degradation of SRPK1.

Dynamic Virtual Inertia and Damping Control for Zero-Inertia Grids

In this paper virtual synchronous generation (VSG) approach is investigated in application to low- and zero-inertia grids operated by grid-forming (GFM) inverters. The key idea here is to introduce dynamic inertia and damping constants in order to keep power gird stable during different types of faults, islanding or large power balance oscillations. In

HSP90AB1‐Mediated Ubiquitin‐Proteasome Degradation of ITGBL1 Promotes Osteosarcoma Progression by Inhibiting Endoplasmic Reticulum Stress‐Induced Autophagy

Advanced Science, EarlyView.
This study delineates a novel HSP90AB1‐ITGBL1 signaling axis governing osteosarcoma. HSP90AB1 promotes K63‐linked ubiquitination and proteasomal degradation of ITGBL1. Restoring ITGBL1 induces reactive oxygen species‐dependent endoplasmic reticulum stress and pro‐death autophagy, suppressing tumor growth and metastasis.
