Free air CO2 enrichment (FACE) experiments in aggrading forests and plantations have demonstrated significant increases in net primary production (NPP) and C storage in forest vegetation. The extra C uptake may also be stored in forest floor litter and in forest soil. After five years of FACE treatment at the EuroFACE short rotation poplar plantation, the increase of total soil C% was larger un...

The gross structures of both the native and oxidised (atherogenic) forms of low density lipoproteins (LDL) were compared using neutron and X-ray solution scattering. Neutron data in 2~20 solutions showed that native LDL is well represented as a quasispherical structure, while X-ray data showed that the internal structure of LDL has lipid in the core and apo-B100 protein and phospholipid headgro...

Abstract Key message The non-linear seemingly unrelated regression mixed-effects model (NSURMEM) and generalized additive (GAM) were applied for the first time in crown width (CW) models of larch ( Larix gmelinii Rupr.), birch Betula platyphylla Suk.), poplar Populus davidiana Dode). radii four directions (CR) exhibited different growth trends responded differently to tree size competition vari...

Hydrogen peroxide (H(2)O(2)), ethylene, 1-aminocyclopropane-1-carboxylic acid (ACC) and salicylic acid (SA) concentrations and ACC synthase (ACS) gene expression were measured to establish whether the high sensitivity of the Populus deltoides x maximowiczii clone Eridano to ozone (O(3)) exposure, compared with the O(3)-resistant Populus deltoides x euramericana clone I-214, is attributable to d...

We propose an approach to accurately detecting two-dimensional (2-D) shapes. The cross section of the shape boundary is modeled as a step function. We first derive a one-dimensional (1-D) optimal step edge operator, which minimizes both the noise power and the mean squared error between the input and the filter output. This operator is found to be the derivative of the double exponential (DODE)...
