Analysis of Offline Transient Power Oscillation and Its Suppression Method in the Microgrid with Multiple Virtual Synchronous Generators

Energies, 2023
When multiple Virtual Synchronous Generators (VSGs) operate in parallel in an islanded grid, power and frequency oscillations will occur when one VSG goes offline.

Evolutionary radiation of large‐bodied gorgonopsians from the lower Abrahamskraal formation of South Africa

The Anatomical Record, EarlyView.
Abstract The middle Permian represents a critical interval in therapsid evolution, when gorgonopsians emerged as some of the first specialized apex predators within terrestrial ecosystems. Despite their significance, the early diversification of Gorgonopsia in Gondwana remains poorly understood due to scarcity and fragmentary material.

Comparative Evaluation of Structure–Processing–Property Relationships in Flax, Hemp, and Cattail Discontinuous fiber Thermoset Composites

Polymer Composites, EarlyView.
Needle punching reorients fibers from in‐plane direction toward z‐direction of the web, resulting in mechanical interlocking of fibers and reduction in the nonwoven mat thickness. ABSTRACT Replacement of glass fiber mats, utilized in large and complex composite parts in the transportation industry, with natural fiber mats requires knowledge of natural ...

Average Model and Controller Design for Virtual Synchronous Generator

IEEE Access
This paper proposes a novel systematic design procedure for virtual synchronous generators (VSGs) and develops an average VSG model. The VSG comprises distributed generators, an energy storage system consisting of a battery and a DC-DC converter (DDC ...

Laser‐Direct Printed 2D Material‐Based Heterostructure for the Fabrication of Electronic Devices

Small, EarlyView.
The Digital Laser‐Induced Forward Transfer (LIFT) approach is employed to pattern and stack 2D materials with micrometer‐scale precision. PdSe2 and MoSe2 are assembled into vertical p–n junctions, with graphene serving as a transparent electrode. The resulting laser‐transferred heterostructures exhibit high material quality and stable rectifying ...

Filtering of the minichromosomal VSG set.

, 2023
The VSG set was filtered based on RNA-seq read-mapping profiles. VSGs displaying full coding sequence activation were included in the analysis. VSGs with mapped reads restricted to the C-terminal coding sequence were excluded from further analysis. These

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.

Mapping replication dynamics in Trypanosoma brucei reveals a link with telomere transcription and antigenic variation

eLife, 2016
Survival of Trypanosoma brucei depends upon switches in its protective Variant Surface Glycoprotein (VSG) coat by antigenic variation. VSG switching occurs by frequent homologous recombination, which is thought to require locus-specific initiation. Here,
