In this paper, we propose a modified susceptible–infected–susceptible model with an infective medium, which describes epidemics transmitted through an infective medium on complex networks. We examine epidemic thresholds for disease spreading by using this new model and compare it with the...

In this work, according to integrated pest management principles, a class of predator–prey system with state-dependent impulsive effects is put forward. In this model, the control strategies by releasing natural enemies and spraying pesticide at different thresholds are considered. The...

Based on a continuous-time model of quasi-hyperbolic discounting, this paper provides an analytically tractable framework of entrepreneurial firms’ investment and capital structure decisions with time-inconsistent preferences. We show that the impact of time-inconsistent preferences depends...

Intra-urban human mobility is investigated by means of taxi trajectory data that are collected in Shanghai, China, where taxis play an important role in urban transportation. From the taxi trajectories, approximately 1.5 million trips of anonymous customers are extracted on seven consecutive...

In classical Laplacian image sharpening, all pixels are processed one by one, which leads to large amount of computation. Traditional Laplacian sharpening processed on CPU is considerably time-consuming especially for those large pictures. In this paper, we propose a parallel implementation of...

This paper examines optimal reorganization strategies during financial distress and securities valuation under asymmetric information. We model strategic interactions between debtholders and equityholders in a game-theoretic setting that can accommodate the varying bargaining powers of the two...

This paper examines optimal debt reorganization strategies in the presence of agency problems arising from information asymmetry between a firm and a bank during financial distress. In particular, in the structural model, we incorporate complete verification strategies for private information...

This paper presents a real options model of alliance formation between two firms for entry into a new market. We analyze how different compensation measures affect the alliance timing and option values. Generally, when profit structures of the two firms before and after an alliance are...
