The global FOM and GMRES algorithms are among the effective methods to solve Sylvester matrix equations. In this paper, we study these algorithms in the case that the coefficient matrices are real symmetric (real symmetric positive definite) and extract two CG-type algorithms for solving generalized Sylvester matrix equations. The proposed methods are iterative projection methods onto matrix Kr...

Many Hamiltonian systems can be recast in multi-symplectic form. We develop a reduced-order model (ROM) for partial differential equations (PDEs) that preserves the global energy. The full-order solutions are obtained by finite difference discretization space and energy preserving average vector field (AVF) method. ROM is constructed same way as (FOM) applying proper orthogonal decomposition (P...

Following the optical imaging of exoplanet candidate Fomalhaut b (Fom b), we present a numerical model of how Fomalhaut’s debris disk is gravitationally shaped by a single interior planet. The model is simple, adaptable to other debris disks, and can be extended to accommodate multiple planets. We find that to not disrupt the belt, Fom b must have a massMpl < 3MJ. Previous mass constraints base...

We propose a machine learning-based method to build system of differential equations that approximates the dynamics 3D electromechanical models for human heart, accounting dependence on set parameters. Specifically, our permits create reduced-order model (ROM), written as Ordinary Differential Equations (ODEs) wherein forcing term, given by right-hand side, consists an Artificial Neural Network...

The High Level Architecture (HLA) is widely used in defense applications as a common framework for modeling and simulation. The Federation Development and Execution Process (FEDEP) is a generalized process to build HLA federations from scratch. However, simulation model design, implementation, testing and execution defined in the FEDEP are time consuming and expensive. The Model Construction En...

The effect of coadministration of fosfomycin (FOM) on glycopeptide antibiotic-induced nephrotoxicity for 3 days was investigated in rats. To induce nephrotoxicity in a short time, gentamicin (GM) was also coadministered. In the present study, FOM decreased glycopeptide antibiotic-induced nephrotoxicity as shown by reduced urinary excretion of N-acetyl-beta-D-glucosaminidase (NAG) as well as few...

Although previously reported terahertz absorbers can achieve high-sensitivity refractive index sensing, the resonant peak is too broad, which leads to a low figure of merit (FOM). Transmissive sensors based on bound states in continuum (BIC) high FOM, but they have some limitations sensitivity. Herein, we propose periodic triple parallel metal bars structure obtain quality, strong field, and mu...

In recent years, multidrug resistance of Escherichia coli has become a serious problem. However, resistance to fosfomycin (FOM) has been low. We screened E. coli clinical isolates with reduced susceptibility to FOM and characterized molecular mechanisms of resistance and reduced susceptibility of these strains. Ten strains showing reduced FOM susceptibility (MIC ≥ 8 μg/mL) in 211 clinical isola...

Changes in biogeochemical cycles and the climate system due to human activities are expected to change the quantity and quality of plant litter inputs to soils. How changing quality of fresh organic matter (FOM) might influence the priming effect (PE) on soil organic matter (SOM) mineralization is still under debate. Here we determined the PE induced by two (13)C-labeled FOMs with contrasting n...
