Stanilov-Tsankov-Videv Theory [PDF]
, 2007 We survey some recent results concerning Stanilov-Tsankov-Videv theory, conformal Osserman geometry, and Walker geometry which relate algebraic properties of the curvature operator to the underlying geometry of the manifold.Comment: This is a ...

Rotating 5D-Kaluza-Klein Space-Times from Invariant Transformations [PDF]
, 2000 Using invariant transformations of the five-dimensional Kaluza-Klein (KK) field equations, we find a series of formulae to derive axial symmetric stationary exact solutions of the KK theory starting from static ones.

Automorphisms of complex reflection groups [PDF]
, 2009 Let $G\subset\GL(\BC^r)$ be a finite complex reflection group. We show that when $G$ is irreducible, apart from the exception $G=\Sgot_6$, as well as for a large class of non-irreducible groups, any automorphism of $G$ is the product of a central ...

EEG–fMRI mapping of asymmetrical delta activity in a patient with refractory epilepsy is concordant with the epileptogenic region determined by intracranial EEG [PDF]
, 2006 We studied a patient with refractory focal epilepsy using continuous EEG-correlated fMRI. Seizures were characterized by head turning to the left and clonic jerking of the left arm, suggesting a right frontal epileptogenic region.

Glauber theory of initial- and final-state interactions in (p,2p) scattering [PDF]
, 1996 We develop the Glauber theory description of initial- and final-state interactions (IFSI) in quasielastic A(p,2p) scattering. We study the IFSI-distortion effects both for the inclusive and exclusive conditions.

Structural and dynamic roles of tandem acyl carrier proteins in aryl polyene biosynthesis in carbapenem-resistant Acinetobacter baumannii. [PDF]
Protein SciAbstract Aryl polyenes (APEs) are critical secondary metabolites in gram‐negative pathogens, synthesized by polyketide synthases that rely on acyl carrier proteins (ACPs) as essential cofactors. Despite their importance, the structural and functional dynamics of tandem ACPs—ApeE and ApeF—have remained largely uncharacterized.

ESO 546-G34: the most-metal-poor, low surface brightness galaxy? [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2011 Abstract We present a re-analysis of spectroscopic data for 23 H ii regions in 12 blue, metal-poor, low surface brightness galaxies (LSBGs), taking advantage of recent developments in calibrating strong-line methods. In doing so, we have identified a galaxy (ESO 546−G34) which may be the most-metal-poor LSBG found in the local Universe ...
