Electron, hole, and exciton states of multishell CdS/HgS/CdS quantumdot quantum well nanocrystals are determined by use of a multiband theory that includes valence-band mixing, modeled with a 6-band Luttinger-Kohn Hamiltonian, and nonparabolicity of the conduction band. The multiband theory correctly describes the recently observed dark-exciton ground state and the lowest, optically active, bri...

An adaptive amplitude distortion effect for audio production is introduced. We consider a versatile model of multiband waveshaping with a limited set of intuitive parameters. We propose a method for adaptive scaling of the characteristic amplitude distortion transfer function. A number of methods to automate other distortion parameters are explored, such as automatic balance between clean and d...

This paper deals with the multiband hysteresis control technique which tracks the desired reference current and provide desired voltage and current waveform with less distortion for grid connected systems. Cascaded H bridge multilevel inverter is used in high power and medium power applications. Multiband tracks the desired reference current and is used for evaluating the performance of multile...

We provide an overview of new theoretical results that we obtained while further investigating multiband robust optimization, a new model for robust optimization that we recently proposed to tackle uncertainty in mixed-integer linear programming. This new model extends and refines the classical Γ -robustness model of Bertsimas and Sim and is particularly useful in the common case of arbitrary a...

A novel method for multiband image segmentation has been proposed. The method is based on segmentation of subsets of bands using multithresholding followed by the fusion of the resulting segmentation achannelso. For color images the band subsets are chosen as the RB, RG and BG pairs, whose two-dimensional histograms are processed via a peak-picking algorithm to effect multithresholding. The seg...

This paper describes an approach of using dynamic Structural Equation Modeling (SEM) analysis to estimate the connectivity networks from resting-state fMRI data measured by a multiband EPI sequence. Two structural equation models were estimated at each voxel with respect to the sensory-motor network and defaultmode network. The resulting connectivity maps indicate that supplementary motor area ...

We calculate the Hall transport in a multiband system with a dominant interband interaction between carriers having electron and hole character. We show that this situation gives rise to an unconventional scenario, beyond the Boltzmann theory, where the quasiparticle currents dressed by vertex corrections acquire the character of the majority carriers. This leads to a larger (positive or negati...

We report on measurements and a detailed analysis of the reversible magnetization of superconducting NbSe2 single crystals. By comparing the experimental data with Ginzburg Landau theory we show that superconductivity in NbSe2 cannot be explained by an anisotropic single-band but by a multiband scenario. Applying a simple two-band model reveals the basic mixed-state parameters, which are quite ...

The rapid development in wireless communications has demanded multiband or wideband antennas to support wireless communication devices such as smart phones, tablets, laptop computers, radar system, satellite communication, airplane, and unmanned airborne vehicle (UAV) radar. It has also demanded compact wireless devices that allow more space to integrate other electronic components. The aim of ...
