For example in epidemiology, the periodic aspect comes from the periodic seasonal effects.
We report on a method of fabricating variable patterns of periodic, high aspect ratio silicon nanostructures with sub-50-nm resolution on a wafer scale.
These parallel-aligned and unidirectional RES NWs exhibit identical sizes, periodic positions, large aspect ratios (length >1 μm, width ≤5 nm) exceeding 300, and ultra-high integration density up to 104 NWs/μm2.
Kinetic parameters were found such that the system exhibited periodic behavior with fundamental aspects of self-replication.
Periodic events underlie many aspects of our lives and some cell molecular oscillators have already been characterized and revealed to be crucial in insuring that the genetic/biochemical/morphological processes occur in their optimal temporal niche.
Activities in child welfare clinics comprise education in all aspects of motherhood, periodic medical and dental examinations, advice on mental health problems, immunization and vaccination, and distribution of welfare foods.
The time domain approach is found to facilitate analysis and interpretation of well-known properties of premixed flames such as excess gain, periodic cutoff and self-similar aspects of flame response.
We show that for experimental designs with periodic stimuli, only a few aspects of the serial dependence are important and these can be estimated reliably via nonparametric estimation of the spectral density of the time series, whereas existing techniques are biased by their assumptions.
This could be improved with the support of the hospital management and by allocating the proper budget for periodic trainings on all such aspects in a tertiary hospital [ 23].
Though aspects of the Periodic Table were intuited by chemists before the 20th Century, in the first half of the 20th Century the Periodic Table was the obvious bridge between physics and chemistry, between the theories of quantum mechanics and the properties of chemical bonds.
