Probability prediction of true‐triaxial compressive strength of intact rocks based on the improved PSO‐RVM model

Deep Underground Science and Engineering, EarlyView.
In this work, we propose an improved particle swarm optimization (PSO) algorithm and develop an improved PSO‐relevance vector machine (RVM) model as a substitute for traditional true‐triaxial testing. The model's high prediction accuracy was validated through comparisons with two other machine learning methods and five three‐dimensional Hoek–Brown type

Enabling flexible, wearable, and implantable electronics with radio frequency‐based wireless charging: Fundamentals, challenges, and emerging applications

FlexMat, EarlyView.
This paper presents a comprehensive review of radio frequency (RF)‐based wireless charging technologies for flexible electronics. In particular, we (i) provide an overview of wireless charging approaches, (ii) investigate the fundamental RF charging principles, covering rectenna design, impedance matching, RF‐to‐DC conversion, and power management, and

Exchange Rate Risk and Deviations From Purchasing Power Parity

International Journal of Finance &Economics, EarlyView.
ABSTRACT This paper proposes a new solution to the purchasing power parity (PPP) puzzles, arguing that investors' higher‐order risk attitudes, combined with higher‐order uncertainty about nominal exchange rates, as reflected by skewness and kurtosis, drive a risk premium that leads to deviations from PPP.

The Efficiency of Green Development Between Eastern and Western Regions of China

International Studies of Economics, EarlyView.
ABSTRACT The Super‐SBM model was utilized to assess and quantify the effectiveness of green development (EGD) in China's eastern and western regions from 2004 to 2020. Building upon this, the kernel density estimation method, the Dagum Gini coefficient method, and the spatial panel convergence model were employed to investigate the dynamic changes ...

The Impact of a Buyer's Incentives and Organizational Structure on Suppliers' Quality

Journal of Operations Management, EarlyView.
ABSTRACT Changes in a buyer organization's incentives and structure can have a significant impact on supply chain performance, such as the quality of sourced components. We examine this relationship using data from a unique quasi‐experiment where one of the two plants of a buyer introduced long‐term quality improvement incentives and a more organic ...

The Application of a Cost Management System Within the Changing Dynamics of Organisations

Strategic Change, EarlyView.
ABSTRACT Contingency theory suggests that cost‐management systems (CMS) must be aligned with organizational and environmental characteristics; however, empirical evidence remains fragmented and is drawn largely from advanced economies. It remains unclear whether the importance of specific contingent factors varies when digital infrastructure, capital ...
