Damping Provision by Different Virtual Synchronous Machine Schemes

2020

The adoption of virtual synchronous machine (VSM) schemes for the control of power converters is gaining more and more attention both in academia and industry. The VSM control strategies fall into the category of grid-forming converter controls, and they are intended for a range of different applications, providing specific services and different kinds of support to the grid. The paper investigates the possibility of damping provision to the system by VSM power converters. Different schemes are considered and compared, showing the opportunity of the investigated solutions through combined modal and time domain analyses. A specific modification of the power synchronization loop is recognized…

Vaginal infection of mice with HSV type 2 variant ER−: A new animal model for human primary genital HSV type 2 infections

1992

Abstract Studying the pathogenesis of vaginal infections in mice with two variants of Herpes simplex virus type 2 (HSV-2) strain ER we observed that both variants ER+ and ER− caused severe vaginitis but only ER+ invaded the CNS leading to lethal neurological disease. In contrast, mice infected with ER− cleared the virus from the vagina and recovered from infection. ER+ and ER− expressed equal levels of thymidine kinase (TK) indicating a TK-independent difference in neurovirulence. Using the non-neurovirulent variant ER−, we were able to investigate humoral immune responses late after infection. Vaginal infection with ER− suppressed serum antibody formation after a secondary systemic HSV-1 i…

Transfection of lipoma cells with papilloma bovine virus subgenomic fragment.

1991

Abstract Lipoma cells with consistent chromosomal aberration have been transfected with plasmids carrying papilloma bovine virus subgenomic fragment (PBV 69). The succesful transformation of the cells was ascerted on the changed growth pattern of the cells in liquid medium, colony formation in soft agar and modified cell appearrance in electron microscopy; transfection with PBV 69 has not been, however, sufficient to immortalize lipoma cells.

SV40 transformed fibroblasts recognize the same 140 kD fibronectin chemotactic fragment as non-transformed cells

1985

SV40-virus-transformed human embryonal fibroblasts show an enhanced chemotactic response to the glycoprotein fibronectin. However, they recognize the same chemotactic active region as non-transformed fibroblasts. The result suggests that an enhancement of chemotaxis by fibroblasts which have been transformed with Simian Virus 40 is due not to the utilization of further chemotactic domains in the molecule, but to an increased sensitivity of the cells to the chemoattractant.

Building a political image on Instagram: A study of the personal profile of Santiago Abascal (Vox) in 2018

2020

Due to Instagram’s growing popularity in Spain, politicians have also begun to turn to this social network increasingly more. Accordingly, this paper analyses the visual and textual discourse of 259 posts published throughout 2018 on the personal Instagram profile of Santiago Abascal, the leader of the party Vox. Insofar as he is the Spanish politician with the highest number of followers on Instagram, the aim here is to analyse how he uses this social network in order to identify possible strategies that justify his growing number of followers. In the analysis, special attention was paid to aspects that might have contributed to the (self)presentation of Abascal and the promotion of his pa…

Performative Archives: The Visual Poetry of bpNichol and Derek Beaulieu

2019

International audience; La performance de l’archive dans la poésie visuelle de bpNichol et Derek Beaulieu”En s’adonnant à la dimension matérielle de l’écriture, la poésie visuelle s’engage dans une voie exploratrice qui pense ensemble matériau, écriture et mémoire. La figure de l’archive se decline au sens métaphorique pour dire cette relation. Elle traverse la tradition poétique en suivant la trace des formes adoptées par les divers supports de l’écrit. Si la poésie visuelle peut se dire archive de l’expérience scripturale, ses inscriptions sont le reflet du flux qui caractérise une esthétique et un environnement conditionnés de maniére croissante par des supports technologiques. Cet artic…

How to Enhance the Sharing of Cyber Incident Information via Fine-Grained Access Control

2022

Industry 4.0 and the ongoing digital transformation along with a large number interconnected machines anddevices increase the role of cybersecurity, cyber incident handling and incident response in the factories of the future (FoF). Cyber incident information sharing plays a major role when we need to formulate situational pictures about FoF operations and environment, and respond to cybersecurity threats related to e.g. the implementation of novel technologies. Sharing of incident information has a major drawback since it may reveal too much about the attack target, e.g. in the case of legacy systems and therefore restrictions may apply. We have developed a proof-of-concept service that co…

Når skjermene inntar kirkerommet - om bruk av digital presentasjonsteknikk i gudstjenester

2021

This study aims to elucidate how modern presentation technology is being used by Norwegian Christian congregations. It is based on a survey answered by 715 church leaders, and the practice revealed is discussed particularly on the basis of Eileen D. Crowley's framework for ‘liturgical media art’. The findings show that presentation technology is used to a significant extent, but mainly as practical, visual support for communication. The article argues that there is a potential to use technology for aesthetic purposes as well.
