A large payload bidirectional quantum secure direct communication (BQSDC) protocol without information leakage is proposed, which is based on entanglement swapping between any two Greenberger-Horne-Zeilinger (GHZ) states. Two remote authorized parties, Alice and Bob, can safely exchange their individual secret messages without worrying about the information leakage problem. Our protocol uses a shared secret GHZ state to overcome the information leakage problem. The shared secret GHZ state plays two roles in the bidirectional communication process: on one hand, it lets Bob know the prepared initial state; on the other hand, it is used for encoding Bob's secret messages. Moreover, our protocol can transmit six bits of secret messages per round communication. Compared with those previous BQSDC protocols, the advantage of our protocol lies in having the following two characters simultaneously: on one hand, it overcomes the information leakage problem; one the other hand, its capacity is as high as six bits per round communication. © 2013 World Scientific Publishing Company.

The present research evaluated the effects of three probiotics on the growth performance and intestinal digestive enzyme activity in fingerlings of grass carp, Ctenopharyngodon idella. Three treatments (T-1, T-2 and T-3) were fed with diets containing different viable bacteria with a final concentration 106CFUg-1 feed (Bacillus coagulans, Rhodopseudomonas palustris and Lactobacillus acidophilus, respectively) and the control was fed with basal diet without probiotics. All the diets supplemented with probiotics resulted in better (P<0.05) final weight, daily weight gain and relative gain rate than control but no significant differences were observed among the treatment groups. The highest protease activity was observed in T-1. However, T-2 and T-3 showed no difference (P>0.05) in protease and cellulase activities compared with the control. The protease activity was higher in the foreintestine than in the hindintestine (P<0.05), and the reverse was observed in cellulase activity. As for amylase activity, there was no difference between foreintestine and hindintestine. In conclusion, the three selected probiotics increased the growth performance of grass carp fingerlings. Furthermore, different digestive enzyme activity was observed in different intestine segment. © 2010 Blackwell Publishing Ltd.

The oral processing of food is a dynamic process which involves a sequence of highly coordinated oral actions and gives desirable sensory experience. Even though this process is perceived to be routine, its governing principles are highly complicated and are still not fully understood. Based on some recent research findings, this paper reviews current understandings on some important issues associated with eating and sensory perception. The review begins with a short introduction to the background of eating studies. This is followed by four sections focusing on different aspects of eating and sensory perception: the important roles of saliva incorporation and implications; the basic features of oral dynamics and what does it mean to sensory perception; the underpinning physical principles of instrumental characterisation of food sensory properties; and finally the psychophysical principles of human sensation and perception. © 2014 Elsevier Ltd.

How to solve the information leakage problem has become the research focus of quantum dialogue. In this paper, in order to overcome the information leakage problem in quantum dialogue, a novel approach for sharing the initial quantum state privately between communicators, i.e., quantum encryption sharing, is proposed by utilizing the idea of quantum encryption. The proposed protocol uses EPR pairs as the private quantum key to encrypt and decrypt the traveling photons, which can be repeatedly used after rotation. Due to quantum encryption sharing, the public announcement on the state of the initial quantum state is omitted, thus the information leakage problem is overcome. The information-theoretical efficiency of the proposed protocol is nearly 100%, much higher than previous information leakage resistant quantum dialogue protocols. Moreover, the proposed protocol only needs single-photon measurements and nearly uses single photons as quantum resource so that it is convenient to implement in practice. © 2014 Chinese Physical Society and IOP Publishing Ltd.

We present a new and efficient method for weighted progressive iteration approximations of data points by using normalized totally positive bases. Compared to the usual progressive iteration approximation, our method has a faster convergence rate for any normalized totally positive basis, which is achieved by choosing an optimal value for the weight. For weighted progressive iteration approximations, we prove that the normalized B-basis of a space provides the fastest convergence rate among all normalized totally positive bases of the space. These results are also valid for tensor product surfaces. © 2009 Elsevier B.V. All rights reserved.

In this paper, two information leakage resistant quantum dialogue (QD) protocols over a collective-noise channel are proposed. Decoherence-free subspace (DFS) is used to erase the influence from two kinds of collective noise, i.e., collective-dephasing noise and collective-rotation noise, where each logical qubit is composed of two physical qubits and free from noise. In each of the two proposed protocols, the secret messages are encoded on the initial logical qubits via two composite unitary operations. Moreover, the single-photon measurements rather than the Bell-state measurements or the more complicated measurements are needed for decoding, making the two proposed protocols easier to implement. The initial state of each logical qubit is privately shared between the two authenticated users through the direct transmission of its auxiliary counterpart. Consequently, the information leakage problem is avoided in the two proposed protocols. Moreover, the detailed security analysis also shows that Eve’s several famous active attacks can be effectively overcome, such as the Trojan horse attack, the intercept-resend attack, the measure-resend attack, the entangle-measure attack and the correlation-elicitation (CE) attack. © 2014, Science China Press and Springer-Verlag Berlin Heidelberg.

Button mushrooms (Agaricus bisporus) were dipped for 2min in different concentrations (1%, 2% and 3%) of alginate, then placed in jars and ventilated continuously with 100% O2 for up to 16d at 4°C. Mushroom respiration rate, weight loss, texture, color, percent open caps, chemical properties and activities of polyphenol oxidase (PPO), and peroxidase (POD) were measured. The results indicate that treatment with alginate coating (2%)+100% O2 maintained a high level of firmness, and delayed browning and cap opening. In addition, alginate coating (2%)+100% O2 also delayed changes in the soluble solids concentration, total sugars and ascorbic acid, and inhibited the activity of PPO and POD throughout storage. Our study suggests that the use of alginate coating under a high oxygen modified atmosphere has the potential to maintain button mushroom quality and extend its postharvest life to 16d. © 2012 Elsevier B.V.

In this paper, He's variational iteration method (VIM) is applied to solve the FornbergWhitham type equations. The VIM provides fast converged approximate solutions to nonlinear equations without linearization, discretization, perturbation, or the Adomian polynomials. This makes the method attractive and reliable for solving the FornbergWhitham type equations. Numerical examples related to two initial value problems are presented to show the efficiency of the VIM. © 2010 Elsevier Ltd. All rights reserved.

In this paper, interval estimation for the Birnbaum-Saunders distribution is considered. The generalized confidence intervals for the shape parameter and some important reliability quantities such as its mean, quantiles and reliability function are explored. A simulation study illustrates the accuracy of these generalized confidence intervals. Finally, two numerical examples are used to illustrate the proposed procedures. © 2012 Elsevier B.V.
