Quantum dense coding in multiparticle entangled states via local measurements

In this paper, we study quantum dense coding between two arbitrarily fixed particles in a (N+2)-particle maximally-entangled states through introducing an auxiliary qubit and carrying out local measurements. It is shown that the transmitted classical information amount through such an entangled quantum channel usually is less than two classical bits. However, the information amount may reach two classical bits of information, and the classical information capacity is independent of the number of the entangled particles in the initial entangled state under certain conditions. The results offer deeper insights to quantum dense coding via quantum channels of multi-particle entangled states.Comment: 3 pages, no figur

Electromagnetic manipulation for anti-Zeno effect in an engineered quantum tunneling process

We investigate the quantum Zeno and anti-Zeno effects for the irreversible quantum tunneling from a quantum dot to a ring array of quantum dots. By modeling the total system with the Anderson-Fano-Lee model, it is found that the transition from the quantum Zeno effect to quantum anti-Zeno effect can happen as the magnetic flux and the gate voltage were adjusted.Comment: 6 pages, 5 figure

Determination of taste receptor type 1 member 1 (TAS1R1) gene polymorphism and association with some body measurements in goats

Umami taste plays a key role in intake of amino acids. It is believed that the taste receptor type 1 member 1 (TAS1R1) and taste receptor type 1 member 3 (TAS1R3) receptors are to function in combination as a heteromeric umami taste receptor in humans and other mammals. Most of the previous studies laid particular emphasis on the taste sensitivity to umami substances or the relation of umami taste sensitivity to variations in candidate umami receptor genes in rodents or in humans. Taste thresholds were associated with body weight. In this article, the objective was to investigate variations in goat TAS1R1 gene and their associations with growth traits in 317 goats by PCR-SSCP and DNA sequencing methods. The results showed two novel single nucleotide polymorphisms (SNPs): HM449123:g. [T3974C, C4037T]. In detail, two different alleles, A and B, were identified and three genotypes were observed, AA, AB, and BB with the frequency distribution of allele B from 0.59 to 0.67 in analyzed populations. The genetic diversity analysis revealed that all PIC values were between 0.34 and 0.37, implying that this locus within TAS1R1 gene possessed moderate genetic diversity in goat. Furthermore, nucleotide sequence analysis showed that HM449123:g. [T3974C, C4037T] resulted in two synonymous mutations. But association analysis demonstrated significant differences between different genotypes and production traits (such as body length, chest circumference and cannon circumference) of Haimen goats. We hope that it can provide valuable information for molecular marker-assisted selection.Key words: Goat, PCR-SSCP, polymorphism, production traits, TAS1R1 gen

Joint DOA and polarisation estimation with crossed-dipole and tripole sensor arrays

Electromagnetic vector sensor arrays can track both the polarisation and direction of arrival (DOA) of the impinging signals. For linear crossed-dipole arrays, as shown by our analysis, due to inherent limitation of the structure, it can only track one DOA parameter and two polarisation parameters. For full four-dimensional (4-D, 2 DOA and 2 polarization parameters) estimation, we could extend the linear crossed-dipole array to the planar case. In this paper, instead of extending the array geometry, we replace the crossed-dipoles by tripoles and construct a linear tripole array. Detailed proof shows that such a structure can estimate the 2-D DOA and 2-D polarisation information effectively in general. A brief comparison between the planar crossed-dipole array and the linear tripole array is performed at last, showing that although the planar structure has a better performance, it is achieved at the cost of increased physical size

A multiple exp-function method for nonlinear differential equations and its application

A multiple exp-function method to exact multiple wave solutions of nonlinear partial differential equations is proposed. The method is oriented towards ease of use and capability of computer algebra systems, and provides a direct and systematical solution procedure which generalizes Hirota's perturbation scheme. With help of Maple, an application of the approach to the $3+1$ dimensional potential-Yu-Toda-Sasa-Fukuyama equation yields exact explicit 1-wave and 2-wave and 3-wave solutions, which include 1-soliton, 2-soliton and 3-soliton type solutions. Two cases with specific values of the involved parameters are plotted for each of 2-wave and 3-wave solutions.Comment: 12 pages, 16 figure
