This paper considers the application of radial basis function neural networks for antenna array systems. An overview of neural network-based direction of arrival estimation is presented, with different radial basis neural networks for signal detection stage. Following that approach, for the case where a large number of neurons can be used, a radial basis function neural network with exact solut...

Biomimetic heterogeneous patterning of hepatic and endothelial cells, which start from randomly distributed cells inside the microfluidic chamber, via the chip design of enhanced field-induced dielectrophoresis (DEP) trap is demonstrated and reported in this paper. The concentric-stellate-tip electrode array design in this chip generates radial-pattern electric fields for the DEP manipulation o...

Polarized radial arrays of cytoplasmic microtubules (MTs) with minus ends clustered at the cell center define the organization of the cytoplasm through interaction with microtubule motors bound to membrane organelles or chromosomes. It is generally assumed that the radial organization results from nucleation of MTs at the centrosome. However, radial MT array can also be attained through self-or...

A high-gain low sidelobe level array antenna that is fed by a radial waveguide and designed to operate over a frequency range is considered. Assuming azimuthally symmetric excitation, the radiation pattern of the circular array is approximated by the space factor for the equivalent circular aperture and a simple and efficient tool is introduced for analysis of the array radiation pattern. The e...

We report design methods for achieving near-unity broadband light absorption in sparse nanowire arrays, illustrated by results for visible absorption in GaAs nanowires on Si substrates. Sparse (<5% fill fraction) nanowire arrays achieve near unity absorption at wire resonant wavelengths due to coupling into 'leaky' radial waveguide modes of individual wires and wire-wire scattering processes. F...

We present millimeter wavelength aperture synthesis observations of TW Hya obtained with the Very Large Array and the BIMA array. Images at 7 mm resolve the dusty circumstellar disk surrounding the star, probing structure to size scales of 0: 00 1 (5 AU). We describe how the long wavelength spectrum and resolved millimeter images constrain the radial distribution of disk surface density.

The Technique, to design multibeam Radial Line Slot Array (RLSA) antennas optimally, was proposed in this study, using high beam squint values produce more slots. This is necessary maintain gain, which dropped due the splitting. A gap also incorporated between slots group overcome a coupling adjacent beams can lessen gains. RLSA models for 42 dual and triple-beams were simulated after prototype...

Radial components of the optic nerve of the mouse were studied by using thin sections and freeze-fracture replicas. The investigations were performed on normal optic nerves, as well as on those undergoing Wallerian degeneration following eyeball enucleation. Normal radial components in thin sections were observed as a series of light lines composed of small electron-lucent dots situated in the ...

Conventional endoscopic ultrasound „ Linear versus radial systems Endoscopic ultrasound (EUS) with f lexible endoscopes is an important diagnostic and therapeutic tool, especially for the local staging of gastrointestinal (GI) cancers, the differentiation between benign and malignant tumors, and interventional procedures, such as biopsies and stent applications. Flexible endoscopy was primarily...
