This paper investigates the sources of business cycle fluctuations in China and India since 1978/81. Under the framework of a standard neoclassical open economy model with time-varying frictions (wedges), we study the relative importance of efficiency, labor, investment and government...

Frequency-dependent selection is theoretically predicted to have an important impact on predator--prey dynamics, but little is understood about this process in nature. We investigated oak--squirrel interactions to test the hypothesis that tree squirrels predate/disperse white oak acorns based on...

Using acorns from Castanea henryi (CH) and Quercus variabilis (QV) with contrasting germination schedule (related to food perishability) and tannin levels, we conducted field experiments in a subtropical forest in Southwest China to investigate how free-ranging Pallas's squirrels (Callosciurus...

We evaluate sources of business cycle fluctuations in China after 1978 with business cycle accounting method developed by Chari, Kehoe, and McGrattan (2007). We find that efficiency wedge, which represents institutional change and technology advance, was the main source of economic fluctuations...

Tephra fallout is an important type of hazard caused by volcanic eruption, and is also one of the main hazards at Changbaishan volcano, Northeast China. Numerical simulation is an effective approach to assess the dispersion of tephra fallout. According to the theory of dispersion model, we...

Reservoir sedimentation is a severe problem because it leads to the loss of reservoir storage capacity. Therefore, the sustainable management of water and sediment constitutes a critical measure in reservoir operation. In this research, a model of similarity-based operation method of water and...

In this paper, we propose a novel method for sparse logistic regression with non-convex regularization Lp (p 1). Based on smooth approximation, we develop several fast algorithms for learning the classifier that is applicable to high dimensional dataset such as gene expression. To the best of...

In this paper, given recent theoretical developments that inflation can exhibit long memory properties due to the output growth process, we propose a new class of bivariate processes to simultaneously investigate the dual long memory properties in the mean and the conditional variance of...

We theoretically investigate the thermopower of silicene systems in an external electric field perpendicular to the silicene sheet. In the absence of the field, we estimate that the thermopower of pure silicene is of order ∼80 μV/K. When a finite field is applied, a comparatively big band gap...

We consider energy (heat) transport in quantum systems, and establish a relationship between energy spread and energy current-current correlation function within linear response theory. The energy current-current correlation is related to thermal conductivity by the Green-Kubo formula, and thus...
