Seed kernels of Euryale ferox are considered a healthy food product in China, and the shells containing high levels of polyphenols are currently unused. To examine the utilization of these by-products, three extracts were obtained from E.ferox seed shells (EFSS) using different solvent systems (EEA, EE-100 and EE-50 extracts). The major composition of the phenolic compounds in these extracts, their in vitro antioxidant properties and their preservative effects on pork sausages were investigated. The major phenolic compounds were gallic acid, epicatechin and rutin. Each extract exhibited strong antioxidant properties, high radical scavenging capacity and inhibition of lipid peroxidation. EE-50 was found to inhibit pH increases and prevent sausage products from lipid oxidation during storage. Furthermore, EE-50 was more effective when used in combination with monascus and NaNO2. The results suggest that EFSS extracts are a potential source of natural antioxidants and could be used for preservation of meat products. © 2015 Wiley Periodicals, Inc. Source

Regioselectivity of methyl α-D-glucopyranoside benzylation using dibutyltin dimethoxide (DBDM) as stannylating agent was probed, general factors affecting regioselectivity have been examined. The results show the O-2 position of glucoside has advantage of being benzylated over the O-6 position. The major isomers of benzyl ether were separated by preparative HPLC method and characterized.

Based on the hadronic level, the value range of the surface gravitational redshift of the neutron star PSR J1614-2230 is tried to be determined in the framework of the relativistic mean field theory. It is found that for the neutron star PSR J1614-2230 the ratio of mass M and radius R is in the range of ∼ 0.1692 to 0.1958 and the surface gravitational redshift is in the range of ∼ 0.4138 to 0.5397. However, for a small mass neutron star, which is calculated with the hyperon coupling constant obtained by the constituent quark model [SU(6) symmetry], the ratio of mass M and radius R is 0.1221 and the surface gravitational redshift is 0.2507. The surface gravitational redshift of the neutron star PSR J1614-2230 is about one times larger than that of the small mass neutron star. Source

Two neural networks that are trained on their mutual output synchronize to an identical time dependant weight vector. This novel phenomenon can be used for creation of a secure cryptographic secret-key using a public channel. Neural cryptography is a way to create shared secret key. Key generation in Tree Parity Machine neural network is done by mutual learning. Neural networks here receive common inputs and exchange their outputs. Adjusting discrete weights according to a suitable learning rule then leads to full synchronization in a finite number of steps and these identical weights are the secret key needed for encryption. A faster synchronization of the neural network has been achieved by generating the optimal weights for the sender and receiver from a genetic process. Here the best fit weight vector is found using a genetic algorithm. In this paper the performance of the genetic algorithm has been analysed by varying the number of hidden and input neurons. © 2015 Kavala Institute of Technology. Source

A new set of nucleon coupling constants (CZ11) is obtained for the relativistic mean field (RMF) theory based on the recent experimental information on the symmetry energy derived from the data from NSCL/MSU. The surface gravitational redshift of a proto neutron star (PNS) is examined within the RMF framework for the baryon octet system by using this set of parameters. It is found that the surface gravitational redshift for CZ11 is smaller than that for GL97. For the CZ11 parameter set, the surface gravitational redshift of a PNS at T=15 MeV is smaller than that at T=0 MeV. It is also found that the surface gravitational redshift corresponding to Mmax/R for the CZ11 parameter set is smaller by about 10 percent than that for GL97, with Mmax being the maximum mass and R being the corresponding radius. © 2011 Springer Science+Business Media, LLC.
