Using a first-principles approach, we investigate the quantum cooling effects in single-molecule junctions. In comparison with the unsubstituted butanethiol single-molecule junction as a refrigerator, the amino-substituted butanethiol single-molecule junction shows significant enhancement in the coefficient of performance (COP). The enhancement is attributed to the appearance of new states in the neighborhood of chemical potentials due to amino substitution. The COP of butanethiol refrigerator can be improved further by the gate voltages. © 2011 American Institute of Physics.

Vision influences taste. It is known that color plays an important role in flavor perception. However, the effect of other features of visual information such as shapes and semantic familiarity of words on the taste perception, particularly on taste sensitivity, is not clear yet. Here we study whether the sweet taste sensitivity of the subjects is affected by such visual inputs. By displaying basic geometric patterns or words with different degrees of semantic familiarity as visual inputs, the subjects rate the hedonic and semantic familiar scores, and taste a series of sucrose solutions, and their sweet sensitivities are accordingly analyzed. Our results show (1) shapes with curvature like circle and ellipse, with higher hedonic scores, increase the sweet sensitivity, whereas angular shapes like square, rectangle, triangle and pentagram do not affect sweet sensitivity; (2) semantic familiar words, with higher hedonic ratings as well, increase sweet sensitivity, whereas unfamiliar words do not affect or even reduce sweet sensitivities. © 2013.

The marine red alga Porphyra is an important marine crop, worth and sim;US$1.3 billion per year. Cultivation research now includes farm ecology, breeding, strain conservation and new net-seeding technologies. The success of cultivation is due, in part, to the high stress tolerance of Porphyra. Many species of Porphyra lose 85-95% of their cellular water during the daytime low tide, when they are also exposed to high light and temperature stress. Antioxidant and mycosporine-like amino acid activities have been partially characterized in Porphyra, but, as we discuss here, the Porphyra umbilicalis genome project will further elucidate proteins associated with stress tolerance. Furthermore, phylogenomic and transcriptomic investigations of Porphyra sensu lato could elucidate tradeoffs made during physiological acclimation and factors associated with life-history evolution in this ancient lineage. © 2010 Elsevier Ltd.

This paper proposes a scheme for constructing an Internet Protocol (IP) version 6 over low-power wireless personal area networks (6LoWPAN) wireless sensor network based on a cluster tree. In the cluster generation algorithm, a cluster tree is always an isolated node with the maximum number of neighbor isolated nodes that launches the cluster generation process; therefore, the total number of cluster heads is minimized. In the cluster-tree construction algorithm, the cluster-tree architecture is proposed, and the cluster-tree construction algorithm minimizes the total number of nodes included in a cluster tree; therefore, the routing cost is reduced. In the cluster-tree repair algorithm, when a cluster head or a cluster associate node fails or moves, a new cluster head or cluster associate node is elected to maintain the cluster-tree topology. This paper compares the performance parameters of Least Cluster Change algorithm with Lowest-ID, Root-based Lowest-ID cluster constructing mechanism, and the proposed scheme, including the cluster-tree topology stability, the routing memory cost, and the routing update cost. The analytical data show that the performance of the proposed scheme is better. © 2006 IEEE.

In this paper, we introduce a modified variational iteration method (MVIM) for solving Riccati differential equations. The solutions of Riccati differential equations obtained using the traditional variational iteration method (VIM) give good approximations only in the neighborhood of the initial position. The main advantage of the present method is that it can enlarge the convergence region of iterative approximate solutions. Hence, the solutions obtained using the MVIM give good approximations for a larger interval, rather than a local vicinity of the initial position. Numerical results show that the method is simple and effective. © 2010 Elsevier Ltd. All rights reserved.

At present, six low-power wireless personal area network uses the broadcasting in the link layer (L2) to achieve the multicast in the network layer (L3). Since broadcasting is expensive, this paper proposes a multicast scheme to achieve the L3 multicast with the L2 unicast. In this scheme, an L3 multicast message is transmitted to each member in a multicast group in the unicast way, so the multicast cost and delay are reduced. This paper also presents the handover algorithm to ensure that the multicast communication can be properly performed when the group members move. This paper evaluates the performance of this scheme, and the results show that this scheme effectively reduces the multicast cost and delay. © 2015 IEEE.

To improve properties of Sn0.7Cu solder, method of particles reinforced was employed. Effects of Ag particle contents (1, 3, 5, 7.5, and 10 vol.%) on spreadability, microstructure, shear strength and creep rupture life of Sn0.7Cu solders have been studied. The experimental results indicate that intermetallic compound (IMC) grows, Shear strength is increased and grains are fined with the increasing of Ag particles. When content of Ag particles is more than 5 vol.%, growth rate of IMC is increased significantly. When the content of Ag is 5 vol.%, the composite solder presents best spreadability and excellent creep rupture property which have maximum spreading area, minimum wetting angle and longest creep rupture life (about 22 times as long as that of Sn0.7Cu solder). © Springer Science+Business Media New York 2012.

In this paper, we introduce a piecewise variational iteration method for treating a nonlinear oscillator of a mass attached to a stretched elastic wire. For the nonlinear oscillator, the present method can produce a good approximation to the exact solution in a very large region, while the standard variational iteration method (VIM) gives a good approximation only in a small region. The numerical results obtained show that the present method does not share the drawback of the standard VIM and can provide very accurate analytical approximate solutions for both small and large values of the oscillation amplitude and parameter. © 2011 Elsevier Ltd.

In this paper, an improved variational iteration method is presented for solving Duffing equations involving both integral and non-integral forcing terms. The main advantage of this modification over the standard variational iteration method (VIM) is that it can avoid unnecessary repeated computation in determining the unknown parameters in the initial solution. Numerical results reveal that the improved method is simple and efficient. © 2010 Elsevier Ltd. All rights reserved.

In wireless distributed sensor networks, one open problem is how to guarantee the reliable relay selection based on the quality of services diversity. To address this problem, we focus on the reliable adaptive relay selection approach and adaptive QoS supported algorithm, based on which we present a Markov chain model, in consideration of different packet states and error control algorithm assignment. The mathematical analyses and NS-2 simulation results show that the proposed relay selection approach could perform better in terms of saturation throughput, reliability, and energy efficiency, compared with the traditional approaches. More importantly, the quality of real-time multimedia streaming is improved significantly, in terms of decodable frame ratio and delay. © 2013 Yong Jin.
