Optical filtering properties in a multichanneled transmission filter based on one-dimensional photonic crystal containing the coupled defects are theoretically investigated. The resonant transmission peaks are designed to be located within the photonic band gap of a defect-free photonic crystal. The number of peaks is directly equal to the number of the coupled defects. The positions of resonan...

Postpartum aortic intramural hematoma (IMH) is a rare but potentially lethal condition. We report a case of aortic IMH with massive hemothorax in a postpartum woman. The patient was a 31-year-old woman who had delivered twins by cesarean section. Two days after delivery, she complained of sudden-onset dyspnea. Chest computed tomography revealed a massive left hemothorax. Exploratory thoracotomy...

Scalp defect management is complicated secondary to reduced laxity in the scalp and forehead area. For reconstruction of larger defects with exposed bone and loss of the periosteal layer, free flap reconstruction is one option for single-stage surgery, although the procedure is lengthy and includes the possibility of flap loss. We successfully performed a single-stage reconstruction of a large ...

We report the histological findings of a reconstructed calcar region four years after femoral impaction bone grafting using metal wire mesh for a case with massive defect of the proximal part of the femur. Thin cortical bone was formed just beneath the metal wire mesh and viable trabecular bone containing a small amount of granulation tissue was observed even at the bone-cement interface. Almos...

Polycrystalline thin-film CdTe is one of the leading materials used in photovoltaic solar cells. One way to improve device performance and stability is through understanding how various process steps alter defect states in the CdTe layer. Low-temperature photoluminescence (PL) studies show a 1.456-eV PL peak in single-crystal CdTe that is likely due to a Cui-OTe defect complex. A similar peak, ...

An automatic defect classification (ADC) system for visual inspection of semiconductor wafers, using a neural network classifier is introduced. The proposed Hyperellipsoid Clustering Network (HCN) employing a Radial Basis Function (RBF) in the hidden layer, is trained with additional penalty conditions for recognizing unfamiliar inputs as originating from an unknown defect class. Also, by using...

We present observations of strength one defects and antidefects formed in isotropic-nematic phase transition in a thin layer of nematic liquid crystals, using a cross-polarizer setup. We measure the widths of the distributions of net winding number in small regions, and determine the exponent characterizing the correlation between defects and antidefects to be 0.26±0.11, in very good agreement ...

Platinum diselenide (PtSe$_{2}$) is a recently-discovered extrinsic magnet, with its magnetism attributed to the presence of Pt-vacancies. The host material these defects itself displays interesting structural and electronic properties, some which stem from an unusually strong interaction between layers. To date, it not clear how unique intrinsic properties PtSe$_2$ will affect induced magnetis...

We propose a new optical biosensor based on photonic crystal with defect layer, which can determine the SARS-CoV-2 concentration in water by mode shift. Two models of dependence refractive index layer pathogen were considered. The optimal parameters for our device and thickness determined. It was also demonstrated that presence absorption investigated structure it is much more advantageous to w...
