The Moran model as a dynamical process on networks and its implications for neutral speciation
dynamical process networks implications
2011/1/5
In genetics the Moran model describes the neutral evolution of a bi-allelic gene in a population of haploid individuals subjected to mutations. We show in this paper that this model can be mapped into...
宁波桑果基地菌核病菌的多样性与ITS 初步分析
桑葚 菌核病 多样性 ITS
2012/9/25
桑葚菌核病又称白果病, 是目前威胁桑葚生产的主要病害, 且具毁灭性. 使用真菌通用引物扩增, 对桑葚菌核病原菌 rDNA 的ITS 保守区进行分析, 结合形态确定病菌种类, 发现宁波天宫庄园桑果观赏基地的菌核病菌有以下4 种: 桑实杯盘菌( Ciboria shiraiana) 、肉阜状杯盘菌(Ciboria carunculoides)、核地杖菌(Scleromitrula shi...
Rate-dependent Damage Evolution and its Influence on Dynamic Behavior of Materials at High Strain Rates
damage evolution dynamic behavior of materials high strain rate adiabatic shearing
2012/9/24
Both experimental and numerical results reveal that dynamic damage evolution depend s on both strain and strain rate. Based on the thermal activ ated mechanism, a new damage evolution law and a new...
The perfect integrator driven by Poisson input and its approximation in the diffusion limit
perfect integrator driven Poisson input approximation diffusion limit
2010/11/15
In this note we consider the perfect integrator driven by Poisson process input. We derive its equilibrium and response properties and contrast them to the approximations obtained by applying the diff...

A New Leptoceratopsid (Ornithischia: Ceratopsia) from the Upper Cretaceous of Shandong, China and Its Implications for Neoceratopsian Evolution
A New Leptoceratopsid Neoceratopsian Evolution
2014/3/26
The leptoceratopsids are a group of small, quadrupedal horned
dinosaurs. They normally have a total body length of about two
meters, and are thus much smaller than the contemporary
ceratopsids [1]....
