Concept Study for a Mach 6 Transport Aircraft

, 2009
A conceptual study is here presented and discusscd on the possibility to transport 200 passengers over a distance of about 7000km in a nominal point-to-point mission through the Atlantic (either London-New York or London-Rio) at a cruise Mach number of 6

DLR TAU Near-Field Simulations for the Third AIAA Sonic Boom Prediction Workshop

, 2021
The accurate prediction of the sonic boom is essential for the development of a future low-boom supersonic aircraft. In this paper, the best practice for predicting near-field pressure signatures with the DLR TAU code is applied for geometries and grids ...

Wee1 kinase differentially regulates maize CDKA2;1a and CDKB1;1

The FEBS Journal, EarlyView.
In eukaryotes, Wee1 kinase inhibits the kinase activity of CDK/Cyc complexes through phosphorylation of a conserved residue in the CDK moiety. Wee1 is also present in plants, but has been scarcely studied. We have studied maize Wee1 regulation of CDKA/CycD2;2a or CDKB/CycD2;2a complexes.

Sonic Boom

, 1991
A status of the knowledge of sonic booms is provided, with emphasis on their generation, propagation and prediction. For completeness, however, material related to the potential for sonic boom alleviation and the response to sonic booms is also included.

Serotypic and Genomic Diversity of Vibrio anguillarum in Rainbow Trout Farms in Turkey: Implications for Vibriosis Control and Vaccine Candidate Selection

Journal of Fish Diseases, EarlyView.
ABSTRACT Outbreaks of vibriosis caused by Vibrio anguillarum are a persistent constraint on rainbow trout (Oncorhynchus mykiss) aquaculture. However, information on the population structure of field strains in Turkey has been lacking. Here, we report the first systematic serotypic, proteomic, and genomic characterization of 23 V.

Transcriptional adapter ADA2 regulates yield and end‐use quality through liquid–liquid phase separation in wheat

Journal of Integrative Plant Biology, EarlyView.
The transcriptional adapter ADA2 interacts with the histone acetyltransferase GCN5 to regulate starch and storage protein content in wheat grains through histone acetylation. ADA2 undergoes phase separation and is modulated by GCN5, affecting histone acetyltransferase activity and gene transcription.

Regulation of the Yersinia pseudotuberculosis Type III Secretion System by the CpxAR Two‐Component System

Molecular Microbiology, EarlyView.
Host tissue cues including temperature, oxygen, and iron availability regulate expression of the Yersinia type III secretion system (T3SS) master regulator LcrF. We found that CpxR inhibits LcrF through an indirect, multi‐factorial mechanism and identified the osmolarity‐sensing OmpR/EnvZ system as an additional regulator of LcrF, highlighting ...
