OBJECTIVE To evaluate the robustness of an appearance-focused intervention to prevent skin cancer in individuals reporting seasonal affective disorder (SAD) symptoms and pathological tanning motives. DESIGN Randomized, controlled clinical trial. SETTING College campus. PARTICIPANTS Four hundred thirty adult female indoor tanners (200 in the intervention group and 230 control participants)...

In the background where there are many factors affecting Japanese families such as decrease of children, change family structures, gender concept, etc., "family'' has become a noticeable issue attracting much attention nowadays. The type traditional named "IE'' was officially regulated in law during Meiji period. After war, legal status eliminated; however, reality, still remains popular. fact,...

We demonstrate second order optical nonlinearity in a silicon architecture through heterogeneous integration of single-crystalline gallium nitride (GaN) on silicon (100) substrates. By engineering GaN microrings for dual resonance around 1560 nm and 780 nm, we achieve efficient, tunable second harmonic generation at 780 nm. The χ2 nonlinear susceptibility is measured to be as high as 16 ± 7 pm/...

The cylindrical Integral Equation -- Generalized Sheet Transition Condition (IE-GSTC) is validated by applying it to physical metasurfaces, i.e. metasurfaces defined material properties and dimensions rather than susceptibility tensor components. previously reported IE-GSTC, which was formulated for zero thickness GSTC discontinuities, extended handle the finite of metasurfaces. A simple analyt...
