Theoretical analysis of telescopic oscillations in multi-walled carbon nanotubes [PDF]

open access: yes, 2011
A simplified theory of the telescopic oscillations in multiwalled carbon nanotubes is developed. The explicit expressions for the telescopic force constants (longitudinal rigidity) and the frequencies of telescopic oscillations are derived.

Braided oscillators [PDF]

open access: yesJournal of Mathematical Physics, 2002
A generalized oscillator algebra is proposed and the braided Hopf algebra structure for this generalized oscillator is investigated. Using the solutions for the braided Hopf algebra structure, two types of braided Fibonacci oscillators are introduced. This leads to two types of braided Biedenharn–Macfarlane oscillators as special cases of the Fibonacci

Neutrino oscillations [PDF]

open access: yesProgress in Particle and Nuclear Physics, 2013
This review summarizes recent experimental and theoretical progress in determining neutrino mixing angles and masses through neutrino oscillations. We describe the basic physics of oscillation phenomena in vacuum and matter, as well as the status of solar, reactor, atmospheric, and accelerator neutrino experiments that probe these phenomena.

Why Brain Oscillations Are Improving Our Understanding of Language

open access: yesFrontiers in Behavioral Neuroscience, 2019
We explore the potential that brain oscillations have for improving our understanding of how language develops, is processed in the brain, and initially evolved in our species.

Empirical formula of crustal torsional oscillations

open access: yes, 2016
Crustal torsional oscillations depend on not only crust properties but also the stellar mass and radius. Thus, one could extract stellar information by identifying the observed frequencies of stellar oscillations with the crustal torsional oscillations ...

Global and Unified Analysis of Solar Neutrino Data [PDF]

open access: yes, 2000
We discuss the status of the solutions of the solar neutrino problem in terms of oscillations of $\nu_e$ into active or sterile neutrinos. We present the results of a global fit to the full data set corresponding to the latest data presented at the $\nu$-

Planar channeling and quasichanneling oscillations in a bent crystal

open access: yes, 2015
Particles passing through a crystal under planar channeling experience transverse oscillations in their motion. As channeled particles approach the atomic planes of a crystal, they are likely to be dechanneled.

Phenomenology of Neutrino Oscillations [PDF]

open access: yes, 2002
We review the status of several phenomenological topics of current interest in neutrino oscillations: (i) Solar neutrino oscillations after the first Sudbury Neutrino Observatory measurements, including both model-independent and model-dependent results;

Deriving structure from evolution: metazoan segmentation

open access: yesMolecular Systems Biology, 2007
Segmentation is a common feature of disparate clades of metazoans, and its evolution is a central problem of evolutionary developmental biology. We evolved in silico regulatory networks by a mutation/selection process that just rewards the number of ...

Optogenetic Stimulation of the Basolateral Amygdala Increased Theta-Modulated Gamma Oscillations in the Hippocampus

open access: yesFrontiers in Behavioral Neuroscience, 2019
The amygdala can modulate declarative memory. For example, previous research in rats and humans showed that brief electrical stimulation to the basolateral complex of the amygdala (BLA) prioritized specific objects to be consolidated into long term ...
