Beneath the cerebral cortex is an inner core of white matter, which is composed of myelinated commissural nerve fibres connecting the cerebral hemispheres via the corpus callosum, and association fibres connecting different regions of a single hemisphere.
"There is a sense that for pragmatic reasons there is an inner core of more experienced chiefs who have greater influence, and this causes some to sit back and let other views prevail," it says.
His life has been scrutinised as scarcely no one else's, but an inner core is still unfathomable.
A naive reading of the lack of a present-day magnetic field (Acuña et al. 1999) is that an inner core is absent, incapable of releasing compositional buoyancy to drive a dynamo.
Key functional amino acid residues, identified by site-directed mutagenesis, reside in the three amphipathic and conserved transmembrane helices II, V and VI, which are supposed to constitute an inner core forming a channel [ 14, 18, 29, 30].
In addition, micelles exhibit a core-shell architecture, that is, they are composed of an inner core and an outer shell [10].
The core polysaccharide region is conserved across bacterial species and is divided into an inner core, generally consisting of 2-keto-3-deoxyoctonoic acid (Kdo) and l-gycero d-manno heptose (Hep) sugars, and an outer core of hexoses and hexosamines.
Based on morphological evidence a hierarchical organisation of the fibre into distinct structural elements has been reported, in particular an inner core was discriminated from an outer skin layer and fibrils running parallel to the fibre axis have been observed [11], [16], [17].
In this material, each particle was consisted of an inner core and a stable concentration-gradient outer layer in which manganese content was gradually increased.
For numerical reasons, the models were run with an inner core present; as such, we further tested the influence of smaller aspect ratios, which proved to be negligible.
