We introduce a nonsymmetric real matrix which contains all the information that the usual Hermitian density matrix does, and which has exactly the same tensor product structure. The properties of this matrix are analyzed in detail in the case of multi-qubit (e.g. spin = 1/2) systems, where the transformation between the real and Hermitian density matrices is given explicitly as an operator sum,...

in order to estimate responses of growth rate and growth hormone of clarias gariepinus to stocking density, fish (initial weight 30.71 ± 0.89 g) were stocked in 120-l tanks at densities of 35, 65, 95, and 125 kg/m3 for 60 days. on day 30 and 60, the fish growth rates were measured, pituitary growth hormone (gh) mrna levels and serum gh concentrations were examined by real-time qpcr and elisa te...

a field experiment was conducted to study the physical properties of maize grain in response to different urea fertilization methods (urea foliar spraying and soil application), three harvest times (grain moisture content of 20, 30 and 40 pecent) in four maize hybrids (three foreign hybrids e.g. ns640, jeta600 , konsur580 and one common hybrid, sc704 as control) at khorram abad agricultural res...

This paper presents a method for learning Peg-In-Hole actions with flexible objects. To learn the actions we parametrize the entire trajectory by a single point and use Kernel Density Estimation to reflect the different variations of the action and the object characteristics. The object is characterized by its elastic behaviour rather than geometric properties. Thereby an action learned for one...

Unsupervised learning of probabilistic models is a central yet challenging problem in machine learning. Specifically, designing models with tractable learning, sampling, inference and evaluation is crucial in solving this task. We extend the space of such models using real-valued non-volume preserving (real NVP) transformations, a set of powerful, stably invertible, and learnable transformation...

since density is considered as one of the most important numerical indices to explain quantitative values of a plant community by affecting on many aspects and activity of ecosystem, on the other hand, awareness about plants distribution pattern in environment is an essential preparation for measurement and study of vegetative cover, therefore, in this research determination of density and dist...
