Fatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 11, Page 4769-4783, November 2025.ABSTRACT At the near‐threshold regime, small irregularities on the surface can interact with the microstructure and affect the nucleation and propagation of cracks. Molecular dynamics is an effective methodology to investigate the damage evolution at this scale, and three types of defects, namely, triangular, rectangular, and crack, are examined.

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.

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 ...

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.

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 ...

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 ...

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 ...

Boundary charges and integral identities for solitons in (d+1)-dimensional field theories
Nuclear Physics B, 2017 We establish a 3-parameter family of integral identities to be used on a class of theories possessing solitons with spherical symmetry in d spatial dimensions.
