This study investigated the rebound behavior of SiO₂ particles normally impacting a planar surface under different temperature conditions. The system has been characterized for an aerosol inlet temperature range of 20–190 °C, flow velocities of 0–20 ms⁻¹, and an impaction surface...

This paper first shows that LUCE (Gentile, 2012), a recent addition to the family of bush-based algorithms, is closely related to OBA (Bar-Gera, 2002). LUCE’s promise comes mainly from its use of the greedy method for solving the quadratic approximation of node-based subproblems, which...

In the portfolio choice literatures and the financial market, diversification and concentration are the focus of debate of philosophers. In this paper, we develop a model of portfolio choice to integrate the diversification strategy and the concentration strategy. Our model relies on the...

This paper reexamines the relation between firm performance and board size using the data of Japanese companies. We find a significantly positive relation between firm performance and board size when the board size is small, but a significantly negative relation when the board size is large. Our...

This paper discusses the past and the status quo of electricity securitization in China. First, the stranded cost securitization in American electricity industry and the ongoing securitization progress in emerging market countries are investigated, which enlightens the way of electricity...

The article proposes a portfolio model subjected to a constraint that captures the investor's goal, with maximum estimation of expected return that is affected by investor sentiment. And we give a solution of the portfolio model by exploring the geometric features. Furthermore, we discuss the...

We propose a suite of statistical methods for inferring a cis-regulatory module, which is a combination of several transcription factors binding in the promoter regions to regulate gene expression. The approach is an integrative analysis that combines information from multiple types of...

Approximately 60% of global greenhouse gas (GHG) emissions are attributable to household consumption, which represents great opportunity to mitigate them. However, most research has focused only on CO2 emissions, and pays limited attention to non-CO2, which accounts for a quarter of household...

Mining, smelting and tailing deposition activities can cause metal(loid) contamination in surrounding soils, threatening ecosystems and human health. Microbial indicators have a crucial role in evaluating soil quality. Selecting the Xikuangshan antimony mine in China as the research area, the...
