obesity and its related emotional and physical consequences are a worldwide problem. obese individuals are usually stigmatized. this study is proposed to assess the correlation between body mass index, gender and age with psychiatric symptoms among iranian students. a number of 9172 students aged 10-18 years (53.5% girls and 46.5% boys) from all provinces of iran participated in this study. dat...

We present a silicon based single optical element that is able to automatically generate desired laser beam polarizations and intensities for the holographic fabrication of woodpile-type photonic crystal templates. A polydimethylsiloxane (PDMS) mold based reflective optics element is fabricated for the generation of five-beam interferences where four beams are arranged four-fold symmetrically a...

Through the use of a multi-layer phase mask to produce fivebeam interference, three-dimensional photonic crystals can be formed through single exposure to a photoresist. In these holographically formed structures, the interconnectivity is controlled by the relative phase difference among contributing beams. Photonic band gaps are calculated and the simulation shows a maximum bandgap of 18% of t...
