It can be viewed as reconstructed Si(557) surface, where a triple step is combined with a single Si(111)7×7 unit. The driving forces for establishing regular step patterns are discussed. © 2001 American Institute of Physics.Kirakosian...
In physics, we have learnt about some motions that are also repeating after a regular interval of time. These types of motions are called periodic motion. The examples of periodic motions are vibration of tuning fork, oscillation of simple pendulum, rotation of earth etc. The frequency of a ...

the frequency of Sundays is one per week, and the frequency of meals is three per day. This is essentially the same as the definition of frequency in physics, with a small difference: The frequency of something is the number of cycles or oscillations of an object or wave per unit of ...
Time period denoted by ‘T’, whereas second (s) is the SI unit of time period. A simple pendulum is an ideal pendulum composed of a point mass (m) suspended by a weightless, inextensible, soft thread and free to vibrate without friction. What is Period? The term period refers to the...
During the past 70 years, the study of infectious disease dynamics has matured into a rich interdisciplinary field at the intersection of mathematics, epidemiology, computational physics, ecology, evolutionary biology, immunology, sociology, and public health. Epidemiology is the branch of science which...
