Lifetime estimation is significant in engineering asset management. However, the estimate of lifetime or failure time could be misleading as it may not reveal the real value. Therefore, confidence intervals need to be built to quantify the prediction uncertainty. For the Gamma process, which is...

In the present paper we describe the structure of the Chinese health care system and sketch its future development. We analyse issues of provider incentives and the actual burden sharing between government, enterprises and people. We further aim to identify a number of current problems and link...

Collecting, storing, discovering, and locating are integral parts of the composition of the library. To fully utilize the library and achieve its ultimate value, the construction and production of discovery has always been a central part of the library's practice and identity. That is the reason...

We consider a high-dimensional dynamic pricing problem under non-stationarity, where a firm sells products to T sequentially arriving consumers that behave according to an unknown demand model with potential changes at unknown times. The demand model is assumed to be a high-dimensional...

This study examines the effective tax rates of listed companies in Australia for a period of 11 years from 1994 to 2004. Two measures of effective tax rate are used: total tax expense divided by pre-tax accounting profit (ETR), and current tax expense divided by pre-tax accounting profit (ETR')....

The development of high-performance, low-cost and large-scale water/seawater splitting bifunctional electrocatalysts still faces huge challenges. Here, we deliver a novel and simple spontaneous redox synthesis strategy to fabricate a self-supported Pt-CoFe(II) layered double hydroxide (LDH)...

Enhancing the economic resilience of agriculture is essential for promoting sustainable and high-quality agricultural development. The emergence of digital technology has created new opportunities in this field. However, existing research predominantly focuses on traditional agricultural factors...

Problem definition: We introduce and formalize a concept termed as conditional leadtime flexibility (CLF), which refers to the industry practice where a manufacturer requests its upstream suppliers to dynamically adjust the leadtimes. We consider an assemble-to-order (ATO) manufacturer's...

Motivation - Fraud is a challenging problem. Its economic effects are clear – worse public services, less financially stable and profitable companies, charities deprived of resources needed for charitable purposes and diminished levels of disposable income of everyone. In every sector...
