The virial equation of state for unitary fermion thermodynamics with non-Gaussian correlations [PDF]

open access: yes, 2007
We study the roles of the dynamical high order perturbation and statistically non-linear infrared fluctuation/correlation in the virial equation of state for the Fermi gas in the unitary limit.

Improved first-principles calculation of the third virial coefficient of helium

open access: yes, 2011
We employ state-of-the-art pair and three-body potentials with path-integral Monte Carlo (PIMC) methods to calculate the third density virial coefficient C(T ) for helium.

Condensation Problem of the Gibbs Single-Phase Statistics on the Lennard-Jones Fluid Example [PDF]

open access: yesЖурнал нано- та електронної фізики, 2013
The accurate expression for the cluster expansion of the configuration integral of interacting particles is considered in the paper. The investigations of this expression indicate the beginning of the gas-liquid transition at the singularity points of ...

AhBWR15, A Novel RLK Gene, Confers Resistance to Ralstonia solanacearum in Peanut

open access: yesPlant Biotechnology Journal, Volume 24, Issue 6, Page 3861-3875, June 2026.
ABSTRACT Bacterial wilt (BW), a severe soil‐borne disease caused by Ralstonia solanacearum, significantly impedes global peanut production. Despite its impact, the mechanisms underlying BW resistance in peanut remain unclear. Herein, we selected the highly resistant variety Nongdahua108 (H108) and the susceptible variety Nongdahua107 (H107) to develop ...

The Virial Equations of the Fourth Order

open access: yesThe Astrophysical Journal, 1968
The virial equations of the fourth order are derived; and the results of certain formal developments needed for their practical usefulness are also given, The equations are then used to locate the neutral points, along the Maclaurin and the Jacobian sequences, that belong to the fourth harmonics.

A New Piecewise EOS for Compressibility Factor Prediction Based on the M-factor Theory [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 2010
In this study for the first time a new description of compressibility factor is rendered based on the virial expansion. The compressibility factor as a function of M-factor is qualitatively and quantitatively expressed.

Stability of KdV Solitons on the Half‐Line: A Study for Nonhomogeneous Boundary Conditions

open access: yesStudies in Applied Mathematics, Volume 156, Issue 6, June 2026.
ABSTRACT We study the orbital stability and asymptotic stability problems for KdV solitons on the right half‐line for nonhomogeneous boundary conditions in the energy space H1(R+)$H^1(\mathbb {R}^+)$. This paper improves the results of Cavalcante and Muñoz [Revista Matemática Iberoamericana 35, no. 6 (2019); and SIAM Journal on Mathematical Analysis 55,

Phase Relations and Melting of SiO2 Under Mantle Conditions Determined From Machine Learning Potentials

open access: yesGeophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract SiO2 is a fundamental component of planetary interiors, yet its high‐pressure melting and phase relations remain uncertain. We develop a machine learning potential with first‐principles accuracy and perform large‐scale two‐phase coexistence simulations to determine the melting curves of stishovite, post‐stishovite, and seifertite up to 160 GPa

INVESTIGATION OF THE PERTURBED VIRIAL EQUATIONS WITH ARBITRARY TEMPERATURE-DEPENDENT SECOND AND THIRD VIRIAL COEFFICIENTS

open access: yes, 2011
In this paper, the perturbed virial equations of state with temperature-dependent virial coefficients are constructed using the Carnahan–Starling (CS) hard sphere equation as reference. Considering the second virial coefficient, some critical properties

MODIFIED NUMERICAL TABLES FOR THE CALCULATION OF NON-SPHERICAL CONTRIBUTION TO SECOND VIRIAL COEFFICIENTS AND THE CORRELATION EQUATIONS OF STATE FOR CO,, CS, AND C6H6 [PDF]

open access: yesJournal of Sciences, Islamic Republic of Iran, 1997
A revised analysis of the effect of long-range nonspherical terms in the intermolecular potential on the second virial coefficient is presented with a preferred Hartree-Fock-Dispersion functional (HFD-C) spherical core treatment of the integrations for ...
