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.

Histone H3.3 G34 Mutations Alter Histone H3K36 and H3K27 Methylation In Cis [PDF]

Journal of Molecular Biology, 2018
Histone H3 encoding genes, particularly H3F3A and H3F3B, the genes encoding the variant histone H3.3, are mutated at high frequency in pediatric brain and bone malignancies. Compared to the extensive studies on K27M and K36M mutations, little is known about the mechanism of G34 mutations found in pediatric glioblastoma or giant cell tumors of the bone.

The impact of financial crises on changes to the models of corporate governance

International Journal of Management and Economics, 2021
This study aims to define the impact of two largest crises of 1997–1998 and 2007–2008 on changes to the models of corporate governance. In order to achieve the assumed aim, a critical analysis of specialist literature and relevant legal regulations has ...

Helix surfaces in the Berger Sphere [PDF]

, 2013
We characterize helix surfaces in the Berger sphere, that is surfaces which form a constant angle with the Hopf vector field. In particular, we show that, locally, a helix surface is determined by a suitable 1-parameter family of isometries of the Berger

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 ...

On the accretion process in a high-mass star forming region - A multitransitional THz Herschel-HIFI study of ammonia toward G34.26+0.15

, 2015
[Abridged] Our aim is to explore the gas dynamics and the accretion process in the early phase of high-mass star formation. The inward motion of molecular gas in the massive star forming region G34.26+0.15 is investigated by using high-resolution ...

The global cross-border mergers and acquisitions network between 1990 and 2021

International Journal of Management and Economics, 2023
The literature is characterized by a lack of research analyzing cross-border mergers and acquisitions (CBM&A) as a network. This article aims to evaluate the topology properties (the geographical and sectoral structure) of the global CBM&A network in ...

Structural and dynamic roles of tandem acyl carrier proteins in aryl polyene biosynthesis in carbapenem-resistant Acinetobacter baumannii. [PDF]

Protein Sci
Abstract 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.
