Exploring the Systemic Impact of External Supply Uncertainty on the Benefits of Demand Information Sharing: A System Dynamics Approach

Systems Research and Behavioral Science, EarlyView.
ABSTRACT Effective collaboration through demand information sharing is essential for supply chain performance. However, growing system complexity often hinders equal information access among firms. This study employs system dynamics models to compare scenarios with and without information sharing, investigating how various types of external supply ...

Short‐Term Multi‐Horizon Line Loss Rate Forecasting of a Distribution Network Using Attention‐GCN‐LSTM

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Accurately predicting line loss rates is crucial for effective management in distribution networks, particularly for short‐term multihorizon forecasts ranging from 1 hour to 1 week. In this study, we propose attention‐GCN–LSTM, a novel method that integrates graph convolutional networks (GCN), long short‐term memory (LSTM) and a three‐level ...

Herbivore and mesocarnivore carcasses trigger divergent short‐term changes in soil properties

Journal of Animal Ecology, EarlyView.
Scavengers reshape nutrient cycles in soils under carrion. Compared to herbivore carcasses, smaller but longer‐lasting carnivore remains boost nutrient levels and microbial activity in dry soils. Abstract Animal corpses act as pulses of organic matter (OM) and serve a key zoogeochemical role by providing localized nutrient inputs to soils and thereby ...

On the stability of nonlinear ARMA models [PDF]

In the present paper we study the stability of a class of nonlinear ARMA models. We derive a sufficient condition to ensure the geometric ergodicity and we apply it to a very general threshold ARMA model imposing a mild assumption on the ...

How Important Are Sectoral Shocks in Australia?

Australian Economic Review, EarlyView.
ABSTRACT We examine the role of sectoral shocks in driving aggregate fluctuations for the Australian economy between 1994 and 2023, comparing the pre‐COVID and COVID periods. Using both statistical and structural factor models for disaggregated industrial production, we find that sectoral shocks accounted for a substantial portion of aggregate ...
