The purpose of this paper is the generalization of structure factor for rods by polygon section in two dimensional phononic crystals. If we use the plane wave expansion method (PWE) for the propagation of acoustic waves in 2D phononic crystals, structure factor will be an important quantity. In order to confirm the obtained relations, we have calculated the band structure for XY and Z vibration...

Many studies in developed regions of the world have confirmed that stigma contributes substantially to the psychological and social burden of epilepsy. Relatively few studies of epilepsy-associated stigma have been conducted in Africa, where much of the world's burden of epilepsy exists. In sub-Saharan Africa (SSA), particularly in rural regions, close family ties, communal living situations, a...

Tunable photonic crystals PCs have attracted much attention in the past decade because of their various applications, such as ultrafast optical filters and optical waveguides with add–drop functionalities. One way of achieving tunability is to make use of ferroelectric materials since the refractive index of ferroelectric materials can be electrically tuned through the electro-optic effect. In ...

A large body of experimental and clinical evidence has strongly suggested that monoamines play an important role in regulating epileptogenesis, seizure susceptibility, convulsions, and comorbid psychiatric disorders commonly seen in people with epilepsy (PWE). However, neither the relative significance of individual monoamines nor their interaction has yet been fully clarified due to the comple...

OBJECTIVES To evaluate the risk factors for rupture of intracranial aneurysms (IAs) using high resolution MRI (HRMRI). METHODS 91 consecutive patients with 106 IAs were reviewed from February 2016 to April 2017. Patients and IAs were divided into ruptured and unruptured groups. In addition to the clinical characteristics of the patients, the features of IAs (eg, shape) were evaluated by CT an...
