After around 50 years of development, the key substance known as polyethylene has been extremely influential in a variety industries. This paper investigates how materials have used domains water, packaging, and medicine to advance contemporary society order comprehend physical chemical alterations that undergoes after being subjected long-term environmental variables (e.g., temperature, light,...

We propose a nonlinear integral equation (NLIE) with only one unknown function, which gives the free energy of the integrable one dimensional Heisenberg model with arbitrary spin. In deriving the NLIE, the quantum Jacobi-Trudi and Giambelli formula (BazhanovReshetikhin formula), which gives the solution of the T -system, plays an important role. In addition, we also calculate the high temperatu...

In this paper, a safe and learning-based control framework for model predictive (MPC) is proposed to optimize nonlinear systems with non-differentiable objective function under uncertain environmental disturbances. The integrates MPC an auxiliary controller in way of minimal intervention. augments the prior nominal incremental Gaussian Processes learn cross-entropy method (CEM) utilized as samp...

Abstract In this paper, films based on sustainable polymers with variable charge have been investigated by non-isothermal thermogravimetry in order to predict their lifetime, which is a key parameter for potential use numerous technological and biomedical applications. Specifically, chitosan has selected as positively charged biopolymer, while alginate chosen negatively biopolymer. Among non-io...

In this study, we report the successful synthesis of a novel Al-based MOF/polybenzoxazine nanocomposite by facile and green approach via thermally induced ring-opening polymerization (ROP). Structural thermal characterization synthesized was accomplished using FTIR, XRD, BET TGA, DSC techniques, respectively. The Al-MOF showed catalytic activity in ROP good stability compared to non-catalyzed s...

The physics of fluid interfaces between domains of different magnetization in the ordered phase of the 3D three–state Potts model is studied by means of a Monte Carlo simulation. It is shown that finite–size effects in the interface free energy are well described by the capillary wave model at two loop order, supporting the idea of the universality of this description of fluid interfaces in 3D ...
