ferulic acid (4-hydroxy-3-methoxycinnamic acid), an effective component of medical plant, is a phenolic acid with low toxicity that can be absorbed and easily metabolized in the human body. the solubility of ferulic acid (fa) is very low in aqueous solutions which can cause problem in preparation of pharmaceutical products, but it can easily be dissolved in oil/water interface of nano-emulsions...

The superfluid weight is an important observable of superconducting materials since it related to the London penetration depth Meissner effect. It can be computed from change in grand potential (or free energy) response twisted boundary conditions a torus geometry. Here we review Bardeen-Cooper-Schrieffer mean-field theory emphasizing its origin as variational approximation for potential. param...

Linear approximations of nonlinear systems can be obtained by fitting a linear model to data from a nonlinear system, for example, using the prediction-error method. In many situations, the type of linear model and the model orders are selected after estimating several models and evaluating them using various validation techniques. Two commonly used validation methods for linear models are spec...
