extramedullary plasmacytomas are plasma cell tumors that arise outside the bone marrow. they are most often located in the head and neck. extramedullary plasmacytomas account for approximately 3 percent of plasma cell malignancies. the diagnosis of an extramedullary plasmacytoma depends upon the demonstration of a monoclonal plasma cell tumor at an extramedullary site with no evidence of multip...

The two-phase thermodynamic (2PT) model is generalized to determine the thermodynamic properties of mixtures. In this method, the vibrational density of states (DoS), obtained from the Fourier transform of the velocity autocorrelation function, and quantum statistics are combined to determine the entropy and free energy from the trajectory of a molecular dynamics simulation. In particular, the ...

a mixing rule for the mixtures of hard-spheres is presented which can be reduced to the standard van der waals mixing rule at low densities. the effectiveness of the mixing rule for the size and energy parameters of lennard-jones fluid are examined by combining them with an equation of state to calculate thermodynamic properties. the results of calculation are compared with the molecular dynami...

The use of multi sources systems of energy progressed significantly in different industrial sectors. Between all the existing sources of energy, batteries and renewable sources, such as photovoltaic and wind, contain the highest specified energy. However, solar and wind energies are not available all the time, their performance is affected by unpredictable weather changes and therefore, it is d...

A new density-functional theory is developed for representing the structural and thermodynamic properties of Lennard-Jones fluids by unifying the modified fundamental measure theory for the short-range repulsion and the first-order mean-spherical approximation ~FMSA! via the energy route for the attractive part of the intermolecular potential. This theory significantly improves the conventional...

Nonequilibrium molecular dynamics simulations are reported at different strain rates (gamma) and thermodynamic state points for a shearing atomic fluid interacting via a Lennard-Jones potential. Our simulations are performed at the Lennard-Jones triple point, a point midway between the triple point and the critical point, and a high point closer to the critical temperature. We find that, for th...

We present a nonlocal density-functional theory of polymeric fluids consisting of freely jointed Lennard-Jones chains with explicit consideration of the segment size, van der Waals attraction, and structural correlations due to chain connectivity. The excess Helmholtz energy functional is derived from a modified fundamental measure theory for the short-ranged repulsion and the first-order therm...

OpenCV is a commonly used computer vision library containing a wide variety of algorithms for the AI community. This paper uses deep parameter optimisation to investigate improvements to face detection using the Viola-Jones algorithm in OpenCV, allowing a tradeoff between execution time and classification accuracy. Our results show that execution time can be decreased by 48% if a 1.80% classifi...

In Chapter 5 we demonstrated that in the case of the Lennard-Jones fluid, the viscosity, pressure and energy exponents are not fixed values. They depend on state point, namely, the temperature and density. We gave the results of simulations for the exponents varying with temperature and density, and we also found that the relationship can be expressed easily by a linear function of both tempera...

an analysis of selected fission fragment angular distributions from helium-ion induced fission is made using an exact theoretical expression. theoretical anisotropies obtained with the transition state model are compared with their corresponding values deduced from the statistical scission model. the nuclear moment of inertia extracted from the model calculations are compared with their estimat...
