Dynamic Marshalling Resilient Control for Permanent Magnetic Maglev Trains Based on Optimized Twin Delayed Deterministic Policy Gradient

Urban Rail Transit
This paper focuses on dynamic marshalling cooperative optimization control of permanent magnetic maglev trains. The traditional distributed controller is difficult to adjust the control parameters adaptively for complex and changeable tracking scenarios,

A New Implementation of Network GARCH Model for Stock Volatility and Co‐Volatility Forecasting

Journal of Forecasting, EarlyView.
ABSTRACT Volatility clustering and spillovers are key features of financial time series with many cross‐sectional assets. While network analysis links similar or correlated stocks and helps trace volatility spillovers, contemporary multivariate ARCH‐GARCH formulations struggle to represent structured network dependence and remain parsimonious.

The Alignment Paradox: A Theory of AI‐Driven Misalignment in HR Systems

Human Resource Management, EarlyView.
ABSTRACT The core principle in strategic human resource management (SHRM) holds that organizations gain competitive advantage from HR systems with practices that work well together (horizontal alignment) and that support overall strategy (vertical alignment).

Deep deterministic policy gradient and graph convolutional networks for topology optimization of braced steel frames

Deep deterministic policy gradient and graph convolutional networks for topology optimization of braced steel frames
We propose a method for topology optimization of braced frames under static seismic loads using Deep Deterministic Policy Gradient (DDPG) and Graph Convolutional Network (GCN). The structure is interpreted as a graph where structural elements and element configurations are represented by the node feature matrix and adjacency matrices, respectively ...

Technology‐Driven Transformation of Compensation Systems: Mapping the Causal Structure of Digital Reward Systems

Strategic Change, EarlyView.
ABSTRACT Traditional reward systems, which are largely salary‐centered and structurally rigid, are no longer sufficient in an era defined by digital transformation. Building on this premise, this study examines how emerging technologies reshape integrated compensation systems by uncovering their causal, mediating, and outcome‐oriented roles.
