Theory regarding metamaterials was developed in the 1960s, aiming to control propagation of electromagnetic waves. Under this scope, research has been focused on realization materials having specific characteristics be invisible and optics fields. These principles have expanded only recently acoustic sector, with capable controlling sound due interference effect between soundwaves periodic stru...

The ability of rod building blocks to self-assemble into supramolecular structures provides unique opportunities for the design of nanoscale materials with predictable properties and functions.1 Extensive efforts thus have been directed toward supramolecular systems for exploration of novel properties and functions that are not easily available without specific assembly of molecular components....

Electron microscopy (EM), combined with image processing, has become an increasingly powerful tool for structural biology. Advances in cryopreservation and imaging, along with increasingly sophisticated computational tools for image processing, allow three-dimensional (3D) structure determination of macromolecules or macromolecular assemblies trapped in native states (1, 2). Structures from non...

We measured the nondipole parameters for the spin-orbit doublets Xe 4d5/2 and Xe 4d3/2 over a photon-energy range from 100 eV to 250 eV at beamline 8.0.1.3 of the Advanced Light Source at the Lawrence Berkeley National Laboratory. Significant nondipole effects are found at relatively low energies as a result of Cooper minima in dipole channels and interchannel coupling in quadrupole channels. M...

This paper investigates a cylindrical nonlinear Schrödinger (cNLS) equation, which describes the cylindrically diverging quasi-plane envelope waves in a nonlinear medium. With the Hirota method and symbolic computation, bilinear form and N-soliton solutions in the form of an Nth-order polynomial in N exponentials are obtained for the cNLS equation. By means of the properties of double Wronskian...

Inverted papilloma is the most common benign tumor of nose and paranasal sinuses arising from lateral nasal wall and middle meatus. Histologically these tumors are composed of epithelial nests that are inverted, exophytic and cylindrical. Here we describe a clinical case of nasal cylindrical cell papilloma, which was treated by endoscopic excision.
