Comparative performance of generalized additive models and multivariate adaptive regression splines for statistical modelling of species distributions
Distribution Environment Fish Freshwater Generalized additive model Multivariate adaptive regression splines
2015/8/21
Two statistical modelling techniques, generalized additive models (GAM) and multivariate adaptive regression splines (MARS), were used to analyse relationships between the distributions of 15 freshwat...
Modelling of light driven CO2 concentration gradient and photosynthetic carbon assimilation flux distribution at the chloroplast level
photosynthesis chloroplast CO2 flux Calvin cycle limiting factors
2012/5/3
The steady state of the two-substance model of light driven carbon turnover for the photosynthetic CO2 assimilation rate is presented. The model is based on the nonlinear diffusion equation for a sing...
Which coordinate system for modelling path integration?

Path integration is a navigation strategy widely observed in nature where an animal maintains a running estimate of its location during an excursion. Evidence suggests it is both ancient and ubiquitou...
Mathematical Modelling of Polarizing GTPases in Developing Axons
Mathematical Modelling of Polarizing GTPases Developing Axons Subcellular Processes
2012/5/2
The aim of this paper is to contribute to the basic understanding of neuronal polarization mechanisms by developing and studying a reaction-diffusion model for protein activation and inactivation. In ...
The Wnt signalling pathway transducing the stabilization of beta-catenin is essential for metazoan embryo development and is misregulated in many diseases such as cancers. In recent years models have ...
Modelling symbiosis in biological and social systems
Modelling symbiosis biological social systems
2010/4/6
We introduce a general mathematical model of symbiosis between different entities by taking into account the influence of each species on the carrying capacities of the others. The modeled entities ca...

桉树人工林 Topog 模拟 土壤含水量指数 雷州半岛
2007/7/10
利用小集水区生态水文学模型－Topog 模型对雷州半岛桉树人工林纪家示范小集水区进行了地形分析和静态水文学模拟。地形分析表明，该集水区地表较为平坦，集水区总面积为0.63 km2，夏季、冬季与春（秋）分平均太阳辐射值分别为44 MJ•m-2•d-1、25 MJ•m-2•d-1 和34 MJ•m-2•d-1。在考虑太阳辐射影响与...
