Nonlinear Behavior Characterization of a 3-Layer Laminated Cantilever Beam System

open access: yesNonlinear Engineering, 2014
This research aims to characterize the nonlinear responses of a 3-layer laminated composite cantilever beam systemsubjected to evenly distributed dynamic excitations, with the employment of the Periodicity Ratio (PR) method.

Temporal variations in suicide attempt rates: A hospital-based study from India

open access: yesJournal of Family Medicine and Primary Care, 2016
Background: Temporal variations of suicide attempts can help to better understand correlates of suicidal behavior. This study attempted to find the diurnal, weekly, and seasonal variations in suicide attempts at a tertiary care hospital in India ...

Subcortical cytoskeleton periodicity throughout the nervous system

open access: yesScientific Reports, 2016
Superresolution fluorescence microscopy recently revealed a ~190 nm periodic cytoskeleton lattice consisting of actin, spectrin and other proteins underneath the membrane of cultured hippocampal neurons.

Investigations into the effect of automobile exhausts on the phenology, periodicity and productivity of some roadside trees

open access: yesActa Societatis Botanicorum Poloniae, 2014
In response to a polluted atmosphere, the phenology of Ficus benyalensis and Eucalyptus sp. was highly affected. The yield of seeds and fruits of Gunincun officinale and Azadirachta indica was lessened at the polluted sites.

Harmony perception by periodicity detection [PDF]

open access: yesarXiv.org, 2013
The perception of consonance/dissonance of musical harmonies is strongly correlated with their periodicity. This is shown in this article by consistently applying recent results from psychophysics and neuroacoustics, namely that the just noticeable ...

Using Floquet periodicity to easily calculate dispersion curves and wave structures of homogeneous waveguides

open access: yes, 2018
Dispersion curves are essential to any guided-wave-related project. The Semi-Analytical Finite Element (SAFE) method has become the conventional way to compute dispersion curves for homogeneous waveguides.

Free-space propagation of optical coherence lattices and periodicity reciprocity.

open access: yesOptics Express, 2015
We examine paraxial propagation of recently introduced optical coherence lattices in free space and demonstrate a novel phenomenon of periodicity reciprocity between their intensity and coherence properties.

Analysis of periodicity of extinction using the 2012 geological timescale [PDF]

open access: yesPaleobiology, 2013
Analysis of two independent data sets with increased taxonomic resolution (genera rather than families) using the revised 2012 timescale reveals that an extinction periodicity first detected by Raup and Sepkoski (1984) for only the post-Paleozoic ...

A Coupled Dynamic Index for ENSO Periodicity

open access: yes, 2018
El Nino–Southern Oscillation (ENSO) is the most active interannual climatic mode, with great global impacts. The state-of-the-art climate models can simulate this dominant mode variability to a large extent.
