Avances en Ciencias e IngenieríaWe estimate the dynamical mass of a Sloan Digital Sky Survey cluster using three techniques: (i) the classical virial theorem, (ii) a recent velocity–dispersion–mass scaling relation, and (iii) the caustic estimator based on the escape envelope in phase ...

Astronomische Nachrichten, Volume 346, Issue 7-8, September 2025.ABSTRACT The physics of heavy‐ion collisions is one of the most exciting and challenging directions of science for the last four decades. On the theoretical side one deals with a non‐abelian field theory, while on the experimental side today's largest accelerators are needed to enable these studies.

Virial theorem for two-body Dirac equation
, 1993 peer reviewedThe quantum-mechanical virial theorem is applied to the two-body Dirac equation. It can be used as a powerful test for solutions of this equation.

Results in Physics, 2018 By the use of complete orthogonal sets of ψ(δ∗)-damping self-frictional (DSF) exponential type orbitals (ψ(δ∗)-DSFETO) introduced by one of the authors, the quantum DSF study of hydrogen-like atomic energies and forces are suggested. Here, δ∗=α∗ or δ∗=pl∗

On Standing Waves of 1D Nonlinear Schrödinger Equation With Triple Power Nonlinearity
Studies in Applied Mathematics, Volume 155, Issue 3, September 2025.ABSTRACT For the one‐dimensional nonlinear Schrödinger equation with triple power nonlinearity and general exponents, we study analytically and numerically the existence and stability of standing waves. Special attention is paid to the curves of nonexistence and curves of stability change on the parameter planes.

ThermoAtmospheric climate science lacks the capacity to integrate thermodynamics with the gravitational potential of air in a classical quantum theory. To what extent can we identify Carnot’s ideal heat engine cycle in reversible isothermal and isentropic ...

Jednadžbe stanja realnih plinova [PDF]
Kemija u Industriji, 2006 The properties of classical real gases, especially their deviations from ideal behaviour, are reviewed. After a brief overview of molecular interactions, the so-called traditional ('primitive') model is presented and shown to be applicable not only to ...

Partition Functions and Mass Action Constants of Plasmas of Light Elements at Higher Temperatures
Contributions to Plasma Physics, Volume 65, Issue 7, August 2025.ABSTRACT We first analyze the relations between the work of Planck and Klimontovich and show that Klimontovich's kinetic theory of non‐ideal plasmas confirms Planck's partition function for the hydrogen plasma. We discuss and check the Planck‐Brillouin‐Larkin (PBL) expressions for Hydrogen with PIMC calculations and derive new partition functions and ...

Modified virial theorem for highly magnetized white dwarfs [PDF]
, 2020 Generally the virial theorem provides a relation between various components of energy integrated over a system. This helps us to understand the underlying equilibrium. Based on the virial theorem we can estimate, for example, the maximum allowed magnetic

The virial theorem and the Price equation
, 2023 We observe that the time averaged continuous Price equation is identical to the positive momentum virial theorem, and we discuss the applications and implications of this connection.Comment: 8 ...
