A thermodynamically consistent quasi-particle model without density-dependent infinity of the vacuum zero point energy

In this paper, we generalize the improved quasi-particle model proposed in J. Cao et al., [ Phys. Lett. B {\bf711}, 65 (2012)] from finite temperature and zero chemical potential to the case of finite chemical potential and zero temperature, and calculate the equation of state (EOS) for (2+1) flavor Quantum Chromodynamics (QCD) at zero temperature and high density. We first calculate the partition function at finite temperature and chemical potential, then go to the limit $T=0$ and obtain the equation of state (EOS) for cold and dense QCD, which is important for the study of neutron stars. Furthermore, we use this EOS to calculate the quark-number density, the energy density, the quark-number susceptibility and the speed of sound at zero temperature and finite chemical potential and compare our results with the corresponding ones in the existing literature

A genetic linkage map of Japanese scallop Mizuhopecten yessoensis based on amplified fragment length polymorphism (AFLP) and microsatellite (SSR) markers

A genetic linkage map of the Japanese scallop Mizuhopecten yessoensis was constructed based on 302 markers, including 263 amplified fragment length polymorphism (AFLP) markers and 39 microsatellite (SSR) markers. The two parental maps were constructed according to the double pseudo-test cross strategy with an F1 progeny of 115 individuals. In the maternal parent, 163 markers were assigned in 20 linkage groups, spanning a total coverage of 2184.9 cM with the average spacing between two adjacent markers was 15.3 cM. In the paternal parent, 155 markers were also mapped into 20 linkage groups, spanning a genetic length of 1882.4 cM with the average marker density of 13.9 cM, respectively. The coverage estimated for the framework maps were 78.3% for the female and 77% for the male without minor linkage groups. Five full alignment linkage groups and four homologous linkage groups could be identified based on the position of 16 high information content SSRs which segregated in the parents. The construction of the M. yessoensis genetic linkage maps here was a part of a genetic breeding program. This linkage map will contribute to the discovery of genes, comparative genomics and quantitative trait loci in Japanese scallop.Keywords: SSR, AFLP, genetic linkage map, Mizuhopecten yessoensi

Zwitterionic 4-carb­oxy-2-(1-methyl­pyridin-1-ium-4-yl)-1H-imidazole-5-carboxyl­ate

In the title zwitterionic mol­ecule, C11H9N3O4, the imidazole and pyridine rings form a dihedral angle of 2.60 (2)°. An intra­molecular O—H⋯O hydrogen bond occurs. In the crystal, pairs of N—H⋯O hydrogen bonds link the mol­ecules into inversion dimers. Weak inter­molecular C—H⋯O inter­actions further consolidate the crystal packing

Wave power extraction by an oscillating water column array embedded in comb-type breakwaters:Performance analysis and hydrodynamic mechanism

Cost-sharing, space-sharing, and multi-function can be achieved through integrating wave energy converters into coastal defense facilities. In this paper, we consider a periodical array of oscillating water columns (OWCs) embedded in the coast-based comb-type breakwater in the presence of the step bottom. Based on the linear potential flow theory and matched eigenfunction expansion method, a semi-analytical model for solving the diffraction and radiation problems of the periodic OWC array is developed. The mathematical model is verified using Haskind relations and energy conservation law. Parametrical studies are carried out to illustrate the hydrodynamic characteristics of the OWC array embedded in the comb-type breakwater. This study also reveals the constructive and destructive interference effects between the breakwater and OWCs. It is found that the wave amplification caused by the projecting caisson produces a constructive effect on the wave power extraction. However, the inherent strong wave reflection caused by the caisson array weakens the wave power extraction, particularly in the sensitive frequency range (i.e., 2 &lt; kh1 &lt; 5.5 in the present investigations).</p
