Programmable Reconfiguration of Hybrid 4D Chiral Metamaterials via Mechanical and Thermal Stimuli
Advanced Engineering Materials, EarlyView.A class of hybrid chiral mechanical metamaterials is designed to achieve programmable reconfiguration through soft networks, hinges, and bilayer joints integrated with rigid units. Responsive to mechanical and thermal stimuli, these structures exhibit large volume changes, tunable deformation pathways, and both positive and negative thermal expansion ...

Известия высших учебных заведений. Поволжский регион: Физико-математические науки, 2021 Background. Equations with random coefficients serve as a mathematical model for a number of problems that arise in practice. The solution, in this case, will be a stochastic process. Its dependence on nondeterministic parameters is interesting.

International Statistical Review, 2007 Summary Mixed Poisson distributions have been used in a wide range of scientific fields for modeling non homogeneous populations. This paper aims at reviewing the existing literature on Poisson mixtures by bringing together a great number of properties, while, at the same time, providing tangential information on general mixtures.

Linking Heat Treatment to Plastic Deformation in Pearlitic Steels Through Mesoscale Modeling
Advanced Engineering Materials, EarlyView.Surface wear on rail and wheel steels results from surface deformation during use. This research uses mathematical models to forecast the plastic behavior of pearlitic steels, connected to the microstructure formed during heat treatment. While the cooling rate impacts the steels’ strength, the size of prior austenite grains and blocks does not ...

Advanced Engineering Materials, EarlyView.Sludge phases with brittle fracture behavior form in AlMgSi alloys with high concentrations of alloying elements and negatively influence their ductility. The phase type mainly depends on the Si content and the concentration of minor alloying elements like Fe, Mn, Cr, and Mo strongly influences the number of sludge particles. The need for sustainable

Ultrahigh Piezoelectricity in Truss‐Based Ferroelectric Ceramics Metamaterials
Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.By leveraging the unique combination of polarization direction and loading state, ultrahigh piezoelectricity is achieved through careful tuning of the relative density and scaling ratio in truss‐based ferroelectric metamaterials. This approach enables the simultaneous realization of extremely high piezoelectric constants and ultralow dielectric ...

The structure of bivariate Poisson distribution
Kodai Mathematical Journal, 1973 In this paper the author has defined the trivariate Poisson distribution and he has clarified the structure of random high vector which has the trivariate distribution law. The discussion is constructed by the next three parts: 1. definition of the trivariate Bernoulli distribution 2. definition of the trivariate binomial distribution 3.
