The origin of perturbations in ionospheric electron density can be traced to various sources.
Additionally, the Tg of an 11- to 14-nm thick PS layer is shown to be the same as that reported by a near-infinitely-dilute PS blend component [Evans and Torkelson Macromolecules2012, 45, 8319] with the same neighboring polymer, which indicates a common physical origin of Tg perturbations in both systems.
I will describe how theoretical predictions of NG and the search for primordial NG signatures in cosmological datasets has become a new and very promising way to discriminate among different models for the origin of primordial perturbations.
Since RMS cells share characteristics of skeletal muscle precursors, the most reliable theory about the origin of RMS suggests that perturbations of the normal mesenchymal development of the skeletal muscle lineage might have a causative role [ 7].
The second kind of perturbation has a non-genetic origin and affects the initial gene activity pattern s0.
Given the importance of marine fish for human and biological exposures, much debate has arisen about the origin of mercury in marine ecosystems and the extent of perturbation by human influences.
These muscle-specific antibodies have curious clinical associations, such as interstitial lung disease, skin findings and vasculitis, with their origin reflecting perturbations of the innate immune systems that may involve molecules like MDA5 (melanoma differentiation gene 5), a target of autoreactity.
Because of the peak intensity decrease, we could not accurately determine the pKa values for these residues, which prevented us from identifying the origin of the pH-induced structural perturbations in the pocket region.
These microscopic fluctuations induced by the external perturbation are at the origin of the local-field effects (LF) and reflect the spatial anisotropy of the material.
But it's that kind of perturbation of a system.
"Drama is about conflict and general degrees of perturbation, disarray.
