Numerous leaf traits exhibit developmental plasticity in response to irradiance, an attribute that maximizes performance in the prevailing light.The use of leaflets to represent whole leaf traits of tree species with compound leaves is common in the acclimation literature.These methods ignore the potential for whole leaf plasticity to augment leafl
Analysis of Doppler frequency shift response mechanism based on OFDM system
OFDM system is widely used in mobile communication because of its high spectral efficiency and strong anti-multipath capability.However, in high dynamic scenarios, the Doppler shift between the transmitter and the receiver destroys the orthogonality between stable the sub-carriers, resulting the interference between the sub-carriers and distortion

A Multiscale Method to Develop Three-Dimensional Anisotropic Constitutive Model for Soils
A multiscale method is presented to develop a constitutive model for anisotropic soils in a three-dimensional (3D) stress state.A fabric tensor and its evolution, which quantify the particle arrangement at the microscale, are adopted to Nutritionals - Standard Tube Feeding describe the effects of the inherent and induced anisotropy on the mechanica
