Recent spectroscopic measurements in a number of strongly correlated metals that exhibit non-Fermi liquid like properties have observed evidence anomalous frequency and momentum-dependent charge-density fluctuations. Specifically, the strange metallic regime cuprate superconductors, there is featureless particle-hole continuum exhibiting unusual power-laws, experiments suggest plasmon mode deca...

A graph $G$ is \textit{$k$-critical} if $\chi(G) = k$ and every proper subgraph of $(k - 1)$-colorable, $L$ a list-assignment for $G$, then \textit{$L$-critical} not $L$-colorable but induced is. In 2014, Kostochka Yancey proved lower bound on the average degree an $n$-vertex $k$-critical tending to $k \frac{2}{k 1}$ large $n$ that tight infinitely many values $n$, they asked how their may be i...

the thermodynamic properties of fluids can be predicted using the global equations of state. among these thermodynamic properties of fluids, we choose the densities of the liquid and vapor phases. this paper considers the application of the crossover model to the vapor-liquid rectilinear diameter of sulfurhexafluoride. we also present a comparison of the crossover model equation with the experi...

We report measurements of the Lorentz-Lorenz coefficient density dependence L(rho), the critical temperature Tc, and the critical density rho c of the fluid 1,1-difluoroethylene H2C2F2. Lorentz-Lorenz coefficient data were obtained by measuring refractive index n, and density rho of the same fluid sample independently of one another. Accurate determination of the Lorentz-Lorenz coefficient is n...

The low-temperature conductivity of low-density, high-mobility, two-dimensional hole systems in GaAs was studied. We explicitly show that the metal-insulator transition, observed in these systems, is characterized by a well-defined critical density, p0 c . We also observe that the low-temperature conductivity of these systems depends linearly on the hole density, over a wide density range. The ...

We study a simple reaction-diffusion population model [proposed by A. Windus and H. J. Jensen, J. Phys. A: Math. Theor. 40, 2287 (2007)] on scale-free networks. In the case of fully random diffusion, the network topology cannot affect the critical death rate, whereas the heterogeneous connectivity can cause smaller steady population density and critical population density. In the case of modifi...

Background: New blood vessels formation is a critical step in tumor progression. Vascular density affects the clinical outcome and prognosis of malignant tumors. The aim of this study was to investigate the relation between the Vascular Endothelial Growth Factor (VEGF) expression and vascular density with the clinical and histopathologic features in oral squamous cell carcinoma (OSCC). &nbsp...

The critical density for the transition to the deconfined phase, at zero temperature, has been evaluated by analyzing the behavior of the gluon condensate in nuclear matter. Due to the non linear baryon density effects, the critical density,ρc turns out about nine times the saturation density, ρ0 for the value of the gluon condensate in vacuum < (αs/π)G 2 >= 0.012 GeV . For neutron matter ρc ≃ ...
