In a recent experiment, a single DNA double helix is stretched and relaxed in the presence of spermidine, a short positive polyelectrolyte, and the pulling force is measured as a function of DNA extension. In a certain range of spermidine concentration, a force plateau appears whose value shows...

The job shop scheduling problem (JSSP) has attracted much attention in the field of both information sciences and operations research. In terms of the objective function, most existing research has been focused on the makespan criterion (i.e., minimizing the overall completion time). However,...

In this paper, we reexamine the mutual fund flow-performance relationship and star effect using mutual funds in China that have unique features of high risk and low performance persistence. Confirming prior studies, we find that fund performance is positively related to flows in subsequent...

Biomass in the form of crop residues and firewood is a major energy source for rural households in China. A survey conducted in the provinces of Shanxi, Zhejiang, and Guizhou shows that 37 percent of rural households use bioenergy for heating and cooking and that bioenergy accounts for 18...

This study develops a consumption-based asset pricing model in which domestic consumers can buy goods from domestic and foreign markets but can only invest in domestic markets. In this model, the exchange rate influences asset prices through the marginal utility of consumption and increases the...

We study a solution of long polyanions (PA) with shorter polycations (PC) and focus on the role of Coulomb interaction. A good example is solutions of DNA and PC which are widely studied for gene therapy. In the solution, each PA attracts many PCs to form a complex. When the ratio of total...

In this paper, we establish a central limit theorem for a large class of general supercritical superprocesses with spatially dependent branching mechanisms satisfying a second moment condition. This central limit theorem generalizes and unifies all the central limit theorems obtained recently in...

Purpose – This paper aims to present a new friction-stir-weld robot for large-scale complex surface structures, which has high stiffness and good flexibility. Design/methodology/approach – The robot system is designed according to manufacturability of large aluminum products in aeronautic...

Purpose This review aims to discuss concepts and theories from cognitive psychology, identifies tourism studies applying them and discusses key areas for future research. The paper aims to demonstrate the usefulness of cognitive psychology for understanding why tourists and particularly pleasure...

We propose a new model of multi-product firms in international trade, where firms choose their product mix based on the products’ attractiveness and endogenous competition. The model is motivated by two novel stylized facts using Danish manufacturing data, which demonstrate the importance of...
