The Cluster Variation Method (CVM), introduced over 50 years ago by Prof. Dr. Ryoichi Kikuchi, is applied to the thermodynamic modeling of the BCC Cr-Fe system in the irregular tetrahedron approximation, using experimental ...

In this paper the Optimized Vector and Marginal Median Self-Organizing Map (OVMMSOM) was proposed as a new method of train Self-Organizing Maps (SOM). This variant is based on order statistics, Marginal Median SOM (MMSOM) ...

The electronic structure and geometry of clusters of the type Li nCum, LinCum+1 (n, m ≤ 4), Lin, and Cun (n ≤ 8) were theoretically investigated using density functional methods. The LinCum bimetallic system is important ...

We propose a new method to probe a possible time evolution of the fine structure constant α from X-ray and Sunyaev-Zel’dovich measurements of the gas mass fraction (fgas) in galaxy clusters. Taking into account a direct ...

In this paper, we implement a new method to test the invariance of the speed of light (c) as a function of redshift, by combining the measurements of galaxy cluster gas mass fraction, H(z) from cosmic chronometers, and ...

Context. Abundance variations in moderately metal-rich globular clusters can give clues about the formation and chemical enrichment of globular clusters. Aims. CN, CH, Na, Mg and Al indices in spectra of 89 stars of the ...

Aims. Given that in most cases just thermal pressure is taken into account in the hydrostatic equilibrium equation to estimate galaxy cluster mass, the main purpose of this paper is to consider the contribution of all three ...

This paper proposes a strategy to avoid false alarms by distinguishing operation effects from damages effects in composite laminates. This strategy is based on active and sensing piezoelectric patches receiving Lamb waves ...

Aims. Our goal is to investigate the formation of star clusters in relatively unperturbed environments. To do this, we studied the five nearby spiral galaxies: NGC 45, NGC 1313, NGC 4395, NGC 5236, and NGC 7793. Methods. ...
