Purpose The purpose of this study was to conduct a comprehensive analysis the impact and its mechanism on transfer agricultural labor forces in surrounding areas resulting from establishment natural reserve, which holds great significance. significance is ecological protection reserve coordinated development local social economy. Design/methodology/approach This first performs an two aspects, a...

Background Reduced ovarian reserve has been known to predict poor ovarian response and poor success rates in infertile women undergoing assisted reproductive technology. Ovarian reserve also decreases with age but the rate of decline defers from a woman to another. The aim of this study was to detect any difference in ovarian reserve as measured by basal serum FSH and AMH between matched cohort...

Application of 3D data derived from images captured using unmanned aerial vehicles (UAVs) in forest biomass estimation has shown great potential in reducing costs and improving the estimates. However, such data have never been tested in miombo woodlands. UAV-based biomass estimation relies on the availability of reliable digital terrain models (DTMs). The main objective of this study was to eva...

There are growing concerns for reserves estimation of incurred but not reported (IBNR) claims in actuarialsciences. In this paper, we propose a copula-based dependency model to capture the relationship betweentwo main IBNR reserve variables, i.e., “time between two successive occurrences” and “delay time”.A maximum likelihood (MLE) method is used estimate parameters model. Asimulation study con...

Recent interest in using marine reserves for marine resource management and conservation has largely been driven by the hope that reserves might counteract declines in fish populations and protect the biodiversity of the seas. However, the creation of reserves has led to dissension from some interested groups, such as fishermen, who fear that reserves will do more harm than good. These perceive...

Recent progress suggests that integrative cardiac reserve is important in coronary artery disease, chronic heart failure, cardiomyopathy, and other cardiovascular diseases. Integrative cardiac reserve includes coronary flow reserve, myocardial reserve, energy reserve, and heart rate reserve. In the case of stress reaction, coronary flow reserve can provide excessive blood and energy supply and ...

This paper presents new, computationally e cient algorithms for solution and estimation of nonlinear dynamic rational expectations models. The innovations in the algorithms are as follows: (1) The entire solution path is obtained simultaneously by taking a small number of Newton steps, using analytic derivatives, over the entire path; (2) The terminal conditions for the solution path are derive...
