Optical characteristics of square-latticed metasurfaces are analyzed by equations derived from a dipole-quadrupole system. For the metasurface composed Si nanospheres, meta-atoms maintain anapole single scatterer, which not affected lattice period. The far-field response thus can be engineered without significantly disturbing near-fields in meta-atoms. In addition, as exhibited with Ag/Si core-...

Wearable electronics have gained opportunities in recent years, and the last decade has been evidence of this growth Wireless Body Area Networks (WBAN). They meet criteria for personalizing healthcare, communication, patient monitoring, tracking, rescue operations. The main challenge WBAN is to handle radiator's coupling with human body. An artificially generated Electromagnetic Band Gap (EBG) ...

purpose: to investigate the results of deep lamellar keratoplasty (dlk) by big bubble method with using shifting bubble sign in patients suffering from keratoconus or corneal opacity methods: in this prospective interventional clinical trial, 20 eyes of 18 patients (10 males and 8 females) who underwent dlk by big bubble method using shifting bubble sign were investigated. mean age of cases wer...

rhabdomyosarcoma is a common primary childhood malignancy that rarely metastasizes to the breast. we report a patient with a primary sinonasal rhabdomyosarcoma metastasizing to the breast, with no distant spread. we describe the imaging appearance of rhabdomyosarcoma on magnetic resonance imaging (mri), particularly on diffusion-weighted imaging (dwi) and apparent diffusion coefficient (adc) se...

Direct simulations of interface roughness effects on transport properties of tunnel structures are performed using the planar supercell stack method. The method allows for the inclusion of realistic three-dimensional rough interfacial geometries in transport calculations. For double barrier resonant tunneling structures, we used our method to analyze the effect of roughness at each of the four ...

Biological studies into antidepressant drug action and into the aetiology of depression were highly active areas of research in the 1960s and 1970s but, arguably, have now lost some of their impetus and direction. Many investigations seem to have come to a natural end and there is a need for the subject to make a quantum leap to promote its development. It is recognized however, that advances h...

A region of the brain called the putamen has a central role in procedural memory consolidation during sleep.
