Comparability in the graph monoid

, 2020
Let $\Gamma$ be the infinite cyclic group on a generator $x.$ To avoid confusion when working with $\mathbb Z$-modules which also have an additional $\mathbb Z$-action, we consider the $\mathbb Z$-action to be a $\Gamma$-action instead. Starting from a

Periodic and Statistically Distributed Surface Texturing of Surface‐Enhanced Raman Spectroscopy (SERS) Sensors with Spatially Selective Signal Mapping

Advanced Physics Research, EarlyView.
Molecular fingerprinting for the detection of biomolecules is highly sensitive and noninvasive through the surface‐enhanced Raman scattering (SERS) effect. This is a report on the commercially competitive performance of gold‐coated periodic structures and black Si (aperiodic) nanostructures as plasmonic SERS substrates.

A Markov approach to credit rating migration conditional on economic states

Canadian Journal of Statistics, EarlyView.
Abstract We develop a model for credit rating migration that accounts for the impact of economic state fluctuations on default probabilities. The joint process for the economic state and the rating is modelled as a time‐homogeneous Markov chain. While the rating process itself possesses the Markov property only under restrictive conditions, methods ...

Forecasting Natural Gas Prices in Real Time

Journal of Applied Econometrics, EarlyView.
ABSTRACT This paper provides a comprehensive analysis of the forecastability of the real price of natural gas in the United States at the monthly frequency considering a universe of models that differ in complexity and economic content. We find that considerable reductions in mean‐squared prediction error relative to a no‐change benchmark can be ...

Design and Validation of Zeroing Neural Network With Active Noise Rejection Capability for Time‐Varying Problems Solving

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Recently, the zeroing neural network (ZNN) has demonstrated remarkable effectiveness in tackling time‐varying problems, delivering robust performance across both noise‐free and noisy environments. However, existing ZNN models are limited in their ability to actively suppress noise, which constrains their robustness and precision in solving ...

Strategic Influencers and the Shaping of Beliefs

The RAND Journal of Economics, EarlyView.
ABSTRACT Influencers, from propagandists to sellers, expend vast resources targeting agents who amplify their message through word‐of‐mouth communication. While agents differ in network position, they also differ in their bias: Agents may naturally read articles with a particular slant or buy products from a certain seller.
