Crystal Structure of the Flagellar σ/Anti-σ Complex σ28/FlgM Reveals an Intact σ Factor in an Inactive Conformation

Crystal Structure of the Bacillus stearothermophilus Anti-σ Factor SpoIIAB with the Sporulation σ Factor σF

F is established, ␴ F (encoded by the SpoIIAC gene) is the first ␴ factor to establish forespore-specific gene expression by inducing expression of other sporulation-specific ␴ factors, which in turn direct the expression of downstream genes necessary for spore development SpoIIAB is also a Cell type-specific transcription during Bacillus sporu-lation is established by ␴ F. SpoIIAB is an anti-␴...

Complex structure-induced deformations of σ-models

We describe a deformation of the principal chiral model (with an evendimensional target space G) by a B-field proportional to the Kähler form on the target space. The equations of motion of the deformed model admit a zero-curvature representation. As a simplest example, we consider the case of G = S × S. We also apply a variant of the construction to a deformation of the AdS3 × S × S (super-)σ-...

development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
