This study analysed the influence of clinical factors on early postoperative seizures in patients with meningiomas and constructed a logistic regression equation for assessing risk factors. Clinical data from 222 patients with meningiomas were collected. The odds ratios (ORs) for independent variables were determined: the ORs for preoperative seizure history and movement disorder were > 1, whe...

The five-dimensional supersymmetric SU(N) gauge theory is studied in the framework of the relativistic Toda chain. This equation can be embedded in two-dimensional Toda lattice hierarchy. This system has the conjugate structure. This conjugate structure corresponds to the charge conjugation.

Distributed solvers provide several benefits, such as linear scalability and good numerical robustness. By separating components with transmission line elements, simulations can be run in parallel on multi-core processors. At the same time, equation-based modelling offers an intuitive way of writing models. This paper presents an algorithm for generating distributed models from Modelica code us...

Soil quality evaluation provides necessary and fundamental data information for understanding the current situation of soils promoting sustainable use land resources. In this study, soil was assessed by developing a structural equation model (SEM) in five aged Chinese fir plantations, located same type, with similar site conditions, Subtropical China. A total 150 samples were taken from stands ...

In this paper idea is to use the Structure Equation Model approach model organizational structure of local governments. The hypothesis that a complex hierarchical can be used for improving efficiency in public sector. final with satisfactory parameters showed possible. Process assumed identification an optimal set questions as directly measured variables. Latent variables are indirectly by cert...

A preconditioned five-equation two-phase model coupled with an interface sharpening technique is introduced for simulation of a wide range of multiphase flows with both high and low Mach regimes. Harten-Lax-van Leer-Contact (HLLC) Riemann solver is implemented for solving the discretized equations while tangent of hyperbola for interface capturing (THINC) interface sharpening method is applied ...
