Methodological guidelines for the characterization of polysaccharide helical structures

open access: yesFood Biomacromolecules, EarlyView.
Abstract Polysaccharide chain conformation is a critical determinant of their physicochemical and biological properties; however, reliable identification remains a significant challenge due to the inconsistent structural evidence yielded by conventional analytical techniques.

Genetic algorithm optimization for blind channel identification with higher order cumulant fitting

open access: yes, 1997
—An important family of blind equalization algorithms identify a communication channel model based on fitting higher order cumulants, which poses a nonlinear optimization prob-lem.

SubDIVIDE: Efficient tensor‐valued diffusion magnetic resonance imaging via joint diffusional variance decomposition modeling and subspace reconstruction

open access: yesJournal of Intelligent Medicine, EarlyView.
SubDIVIDE integrates a physics‐consistent DIVIDE subspace directly into MRI reconstruction. By embedding a low‐rank basis derived from a large DIVIDE signal dictionary into a joint ADMM optimization—together with composite sensitivity maps that absorb inter‐b‐value phase errors—the framework recovers quantitative microstructural maps from highly ...

Predicting Statistical Signatures of Collective Emission in Disordered Color Center Ensembles

open access: yesLaser &Photonics Reviews, EarlyView.
We present an efficient simulation framework for modeling collective emission in disordered ensembles of quantum emitters. The low computational complexity enables large‐scale Monte Carlo simulations. Applied to SiV−${\rm SiV}^{-}$ clusters, it predicts thresholded superradiant bursts set by emitter number and quantum efficiency, as well as interaction‐

Solution to Layover Problemin Airborne Multi-baseline SAR Based on Spectrum Estimation with Fourth-order Cumulant

open access: yesLeida xuebao, 2018
Layover is a difficult problem in SAR imaging technology. Airborne multi-baseline SAR systems are constrained by non-uniform baselines that are also few in number, which means the measured scattering point height is characterized by unacceptable error ...

Thermosensitive Nanostructured Coacervates Developed by Mixing ABA‐ and AB‐Block Copolymers and Their Unique Sustained Release of Nano‐Micelles in a Regulated Manner

open access: yesSmall, EarlyView.
Polyion complex micelles composed of blends of ABA and AB block copolymers can form coacervates with a hexagonally packed cylinder nanostructure after heating. The resulting coacervates can release the micelles under physiological conditions in a zero‐order kinetics, possessing cargo proteins.

A Cumulative Study on Differential Transform Method

open access: yesInternational Journal of Mathematical, Engineering and Management Sciences, 2019
Many real-world phenomena when modelled as a differential equation don't generally have exact solutions, so their numerical or analytic solutions are sought after. Differential transform method (DTM) is one of the analytical methods that gives the solution in the form of a power series. In this paper, a cumulative study is done on DTM and its evolution

A fourth-order cumulant orthonormal propagator rooting method based on Toeplitz approximation

open access: yesEURASIP Journal on Wireless Communications and Networking, 2020
A novel Toeplitz fourth-order cumulant (FOC) orthonormal propagator rooting method (TFOC ‐ OPRM) of direction-of-arrival (DOA) estimation for uniform linear array (ULA) is proposed in this paper. Specifically, the modified (i.e., reduced-dimension) FOC  (

Multi‐Scale 3D Printing of Magnetic Polymer Nanocomposites with Controlled Particle Dispersion and Hyperthermic Response

open access: yesSmall, EarlyView.
Dispersion of magnetic nanoflowers in trimethylolpropane ethoxylate triacrylate to generate photocurable nanocomposites is described. Particle dispersion provides processability and target AC‐field stimulated temperature increases. Complex (DLP) printed structures with submicron features are demonstrated, and the potential for stimulated release of ...
