A preliminary proposal for an original classification of garden plants based on the study of their phenological periodicity and their side-runs
shrubs use of plants phenological groups
2015/3/4
A model group of garden plants (shrubs) was used to observe and evaluate phenological periodicity and new ways of its
practical use in landscaping. The experiment focused on the aesthetically most i...
Reproductive maturation and diel reproductive periodicity in western Gulf of Maine haddock
haddock Gulf of Maine diel reprodutcive periodicity reproductive maturation final oocyte maturation maturity index
2014/12/11
A new macroscopic ovarian reproductive maturity index for haddock, Melanogrammus aeglefinus L, was developed to improve field collection of reproductive stage data. The index was tested, validated and...
We consider the problem of detecting the periodic part of a function given the observations of some input/output tuples (xi,yi). As they are known for being powerful tools for dealing with such data, ...
Do Circulating RSV-Genotypes Affect Established Biennial Epidemic Periodicity in Zagreb Region?
Biennial Cycle Respiratory Syncytial Virus Types A and B Genotypes
2013/1/31
Objective: The biennial epidemic pattern of respiratory syncytial virus (RSV) circulation in Croatia has been preserved and could not be related to climatic factors and the predominant RSV subtypes. T...
Periodicity of Rauzy scheme and substitutional systems
combinatorics on words periodicity Bernside type problems periodicity
2011/8/22
Abstract: In the paper the notion of {\em Rauzy scheme} is introduced. From Rauzy graph Rauzy Scheme can be obtaining by uniting sequence of vertices of ingoing and outgoing degree 1 by arches. This n...
Periodicity of Retz ius lines in fossil Pongo from South China
Pongo South China periodicity of Retz ius lines extant apes fossil apes
2014/3/26
Periodicity of Retzius lines is a key factor in dental development. In this study, we examined the periodicity of Retzius lines in
fossil Pongo from South China using polarized light microscope o...

Computing (or not) Quasi-Periodicity Functions Tilings
2011/3/2
We know that tilesets that can tile the plane always admit a quasiperiodic tiling [4, 8], yet they hold many uncomputable properties [3, 11, 21, 25].The quasi-periodicity function is one way to measur...

A new periodicity concept for time scales
Periodic time scale periodic function shift operator
2011/1/20
By means of the shift operators we introduce a new periodicity concept on time scales. This new approach will enable researchers to investigate periodicity notion on a large class of time scales whose...
In this note we show that the restriction of the cotangent bundle $\Omega_{\mathbb P}^2$ of the projective plane to a Fermat curve $C$ of degree $d$ in characteristic $p \equiv -1 \mod 2d$ is, up to t...
On the range, local times and periodicity of random walk on an interval
range random walk local times periodicity
2010/12/9
The range, local times, and periodicity of symmetric, weakly asymmetric and asymmetric random walks at the time of exit from a strip with N locations are considered. Several results on asymptotic dist...
Novel 3D Hollow Optical Waveguide with Lateral and Vertical Periodicity for Tunable Photonic Integrated Circuits
3D Hollow Optical Waveguide Lateral Vertical Periodicity Tunable Photonic Integrated Circuits
2015/7/17
A novel design-flexible 3D-hollow-waveguide with lateral- and vertical-periodicity has been demonstrated. A high-index-contrast-grating-(HCG), introduced as a lateral-periodicity, provides vertical as...
Effects of Different Water and Nitrogen Levels on the Yield and Periodicity of Pistachio（Pistacia vera L.）
Fertigation Drip Irrigation Pistachio Evapotranspiration Yield
2009/1/12
The effects of 2 irrigation intervals (If1: 7 days and If2: 14 days), 4 nitrogen doses (Ng, N0, N1, N2 and N3) and 2 crop coefficients (Kpc1: 0.60 and Kpc2: 0.90) on pistachio nut fertigation were stu...
PERIODICITY FOR A COOPERATIVE SYSTEM ON TIME SCALES
time scales cooperative system coincidence degree continuation theorem periodic solutions
2008/11/28
In this paper, by using the method of coincidence degree theory, we explore the existence
of periodic solutions for a cooperative ecological model on time scales.
Diel periodicity in both sei whale vocalization rates and the vertical migration of their copepod prey observed from ocean gliders
Diel periodicity both sei whale vocalization rates the vertical migration their copepod prey observed ocean gliders
2014/5/16
The daily activity cycles of marine predators may be dictated in large part by the timing of prey availability. For example, recent studies have observed diel periodicity in baleen whale vocalization ...
