Parameter Estimation of Polynomial-Phase Signals

Известия высших учебных заведений России: Радиоэлектроника, 2020
Introduction. Polynomial phase signals frequently appear in radar, sonar, communication and technical applications. Therefore, estimation of polynomial phase coefficients of such signals is an urgent problem in signal theory. Currently, a large number of

Wearable Smart Patches on Sustainable Chitosan With Reversible Microbial Growth‐Inhibitory Properties

Advanced Functional Materials, EarlyView.
ABSTRACT Chitosan, a polysaccharide upcycled from biowaste, has long promised sustainable, biocompatible, and antimicrobial films and devices, an appeal reinforced by its recent regulatory recognition, with several chitosan‐based antibacterial dressings gaining clearance through the Food and Drug Administration's 510(k) pathway.

Faster algorithms for the characteristic polynomial [PDF]

Proceedings of the 2007 international symposium on Symbolic and algebraic computation, 2007
A new randomized algorithm is presented for computing the characteristic polynomial of an n x n matrix over a field. Over a suffciently large field the asymptotic expected complexity of the algorithm is O(nθ)field operations, improving by a factor of log n on the worst case complexity of Keller-Gehrig's algorithm [11].

Melanin's Role in Balancing Mechanical Strength and Reproductive Output in Environmentally Stressed Fungal Spores

Advanced Functional Materials, EarlyView.
Melanin content directly controls fungal spore mechanical properties, with pigmented spores achieving rupture forces two orders of magnitude higher than hyaline spores. Environmental stress drives this quantity‐quality tradeoff; stressed species invest energy in melanin‐reinforced, mechanically superior thick‐walled, super‐hydrophobic spores, while ...

A Polynomial Preconditioner for the CMRH Algorithm [PDF]

Mathematical Problems in Engineering, 2011
Many large and sparse linear systems can be solved efficiently by restarted GMRES and CMRH methods Sadok 1999. The CMRH(m) method is less expensive and requires slightly less storage than GMRES(m). But like GMRES, the restarted CMRH method may not converge.

Solving Simple Stochastic Games with Few Random Vertices [PDF]

Logical Methods in Computer Science, 2009
Simple stochastic games are two-player zero-sum stochastic games with turn-based moves, perfect information, and reachability winning conditions. We present two new algorithms computing the values of simple stochastic games.

Ionic Gating of Liquid‐Crystal‐Like Pteridine Assemblies Enables Tunable Light Scattering

Advanced Materials, EarlyView.
Tunable optical properties emerge through developmentally regulated ionic gating, which transforms disordered, ultraviolet (UV)‐absorbing organelles into concentrically ordered, liquid‐crystal‐like light scatterers. By integrating analyses of pteridine composition, potassium‐dependent assembly, hierarchical ultrastructure, and optical behavior, the ...

Determining Composition–Structure–Property Relationships in Quaternary Perovskitoids Through Megalibraries

Advanced Materials, EarlyView.
A method to synthesize 1 million compositionally distinct Cs3Bi2‐𝛼Sb𝛼Br9−xIx across a quaternary compositional space on a single glass substrate is presented. High‐throughput characterization is then used to map the interplay of composition, structure, and bandgap.

Spontaneous Nanopatterning and Strain Relaxation in SiGe Layers Grown by Oxidative Solid‐Phase Epitaxy

Advanced Materials Interfaces, EarlyView.
Thin SiGe buffer layers are grown by oxidative solid‐phase epitaxy, resulting in a nanopatterning of varying Ge concentration across the surface of the sample. The nanopatterning is caused by a hexagonal network of dislocations on the SiGe/Si(111) interface, and is visible by scanning electron microscopy, providing a non‐destructive method for ...
