Optimizing Inertia Estimation in Virtual Synchronous Generators With MMC-Based Proportional Integral and Model Predictive Control Strategies

IEEE Access
The increasing integration of renewable energy sources influences the power grid, resulting in a reduction in the traditional inertia supplied by synchronous generators.

An allele-selective inter-chromosomal protein bridge supports monogenic antigen expression in the African trypanosome

Nature Communications, 2023
UPF1-like helicases play roles in telomeric heterochromatin formation and X-chromosome inactivation, and also in monogenic variant surface glycoprotein (VSG) expression via VSG exclusion-factor-2 (VEX2), a UPF1-related protein in the African trypanosome.

The Role of Vaginal Oestrogen Therapy in Postmenopausal Women With Pelvic Organ Prolapse: Does It Have Any Impact on Perioperative Outcomes? A Systematic Review of Randomised Controlled Trials

BJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.
ABSTRACT Background Pelvic organ prolapse (POP) affects up to 50% of postmenopausal women, negatively impacting sexual function and quality of life. While surgery remains the primary treatment, increasing attention has been given to perioperative vaginal oestrogen therapy and its potential impact on surgical outcomes.

Sharing VSG Operation with Synchronous Generator

Journal of Physics: Conference Series, 2022
Abstract While several synchronous generators (SGs) are substituted through virtual synchronous generators (VSGs), some SGs remain in today’s microgrids. And the majority of the research assumes that VSG mimics SG characteristics, allowing it to function in parallel among SGs. However, few studies have gone to great lengths to study this

VSG Control Strategy Incorporating Voltage Inertia and Virtual Impedance for Microgrids

Energies, 2020
Virtual synchronous generator (VSG) control lacks voltage inertia and powerful decoupling capabilities. The voltage of the distributed generator (DG) unit controlled by the VSG will be easily affected by power fluctuations and high-frequency noise, and ...

Reducing opioid use for chronic pain with a group‐based intervention: Economic evaluation using randomised controlled trial data

Addiction, EarlyView.
Abstract Background and aims Long‐term strong opioid use for chronic non‐malignant pain (CNMP) represents a significant public health challenge, associated with reduced health‐related quality of life (HRQoL) and increased mortality. The Improving the Wellbeing of people with Opioid Treated CHronic pain (I‐WOTCH) trial demonstrated that a multicomponent

Gut microbiome shifts in adolescents after sleeve gastrectomy with increased oral-associated taxa and pro-inflammatory potential

Gut Microbes
Bariatric surgery is highly effective in achieving weight loss in children and adolescents with severe obesity, however the underlying mechanisms are incompletely understood, and gut microbiome changes are unknown.

Trypanosoma brucei ATR Links DNA Damage Signaling during Antigenic Variation with Regulation of RNA Polymerase I-Transcribed Surface Antigens

Cell Reports, 2020
Summary: Trypanosoma brucei evades mammalian immunity by using recombination to switch its surface-expressed variant surface glycoprotein (VSG), while ensuring that only one of many subtelomeric multigene VSG expression sites are transcribed at a time ...

Trypanosoma brucei TIF2 and TRF Suppress VSG Switching Using Overlapping and Independent Mechanisms. [PDF]

PLoS ONE, 2016
Trypanosoma brucei causes debilitating human African trypanosomiasis and evades the host's immune response by regularly switching its major surface antigen, VSG, which is expressed exclusively from subtelomeric loci.
