In the current design of borehole heat exchangers (BHEs), the ground is commonly considered to be homogenous. However, in a layered subsurface, thermal performance of BHE can deviate drastically with different strata. Thereby, analysis of the heat transfer of a BHE with different geological...

Facing electoral uncertainty, a government chooses its exchange regime in a trade-off among three incentives: (i) tying the hands of its opponent should it lose the election; (ii) facilitating its own future policy implementation should it win the election; and (iii) increasing its chance of...

Conventional wisdom has held that a fixed exchange rate regime induces more fiscal discipline, but Tornell and Velasco (1995, 1998) argue the opposite. Using a dynamic model with fragmented fiscal policymaking, this paper evaluates the two arguments in a single framework and shows that (1)...

Previous research on online consumer purchases has focused on increased purchases and neglected decreased purchases. However, factors impacting these purchases are different. Drawing on the two-factor theory, in this paper, the authors compare factors affecting increase and decrease in Chinese...

The recent decade has witnessed the increasing popularity of recommender systems, which help users acquire relevant commodities and services from overwhelming resources on Internet. Some simple physical diffusion processes have been used to design effective recommendation algorithms for...

By making use of two observing facts for many natural and social networks, i.e., the nodes’ diversity, and the disassortative (or assortative) properties for biological and technological (or social) networks, a simple and elegant model with three kinds of nodes and deterministic selective...

A railway transportation system can be represented by a bipartite network consisting of trains and stations, where a train is connected to all stations where it stops. In this paper, motivated by the resource-allocation process taking place on networks, we design a method to project a Chinese...

Recent empirical observations suggest a heterogeneous nature of human activities. The heavy-tailed inter-event time distribution at the population level is well accepted, while whether the individual acts in a heterogeneous way is still under debate. Motivated by the impact of temporal...

In recent years, the well-developed Vicsek model has attracted more and more attention. Unfortunately, in-depth research on its convergence speed is not yet completed. In this paper, we investigate some key factors governing the convergence speed of the Vicsek model with the assistance of...

By using the random interchanging algorithm, we investigate the relations between average distance, standard deviation of degree distribution and synchronizability of complex networks. We find that both increasing the average distance and magnifying the degree deviation will make the network...
