one of the prominent shophists lived in 4th and 5th hegira centuries (11th & 12th ad centuries) is ibn bakooyeh shirazi. in a poetic verse that saadi (14th ad century) mentioned baba koohi as pseudonym for ibn bakuyeh shirazi and within a phrase written by isa ibn joneid shirazi (15th ad cen.) at tazkereh-e- hezar mazar (literally hgiography of thousand tombs) book with title of babakoohi as we...

Network analysis has been a major research area over the last ten years, driven by interest in biological networks, cyber attacks, social networks, and criminal or terrorist organizations. This range of applications is illustrated in Figure 1. Detection of a covert community is most likely to be effective if the community exhibits high levels of connection activity. However, the covert networks...

An ideal band-pass filter removes the frequency components of a time series that lie within a particular range of frequencies. In practice, it is difficult to construct an "ideal" band-pass filter as it requires an infinite number of data points. Therefore, an approximation to an ideal filter is used to extract the components of a time series in a particular frequency range, such as business cy...

The preparation of concentration gradients of reactive molecules is fundamentally important for many research fields including biology, pharmaceutical and chemical engineering (Kim et al. 2010; Lin and Levchenko 2015; Sackmann et al. 2014; Sant et al. 2010; Wu et al. 2010). To generate concentration gradients, microfluidic gradient generators (MGGs), including flow based and (Abe et al. 2015; C...

Imagine an Olympic gymnast and you conjure up a picture of a small, slight child accomplishing dazzling feats on the vault, asymmetric bars, beam, or floor area. Now look back at the Atlanta Olympics. The same dazzling feats, but most of the gymnasts were no longer children. Yes, they were small and slight, but they had breasts and hips and waists. Female Olympic gymnastics has come full circle...

Introduction There are three factors which are used to control the amount or dose of radiation received from a source. The radiation exposure can be managed by a combination of these factors; • Time: reducing the time of an exposure leads to reduction of the effective doses proportionally. • Shielding: refers to a mass of absorbing material placed around a reactor or other radioactive source in...
