How to Establish Clinical Prediction Models
A clinical prediction model can be applied to several challenging clinical scenarios: screening high-risk individuals for asymptomatic disease, predicting future events such as disease or death, and assisting medical decision-making and health education. Despite the impact of clinical prediction models on practice, prediction modeling is a complex process requiring careful statistical analyses ...
متن کاملHow to establish universal block-matrix factorizations
A general method is presented for establishing universal factorization equalities for 2×2 and 4×4 block matrices. As applications, some universal factorization equalities for matrices over four-dimensional algebras are established, in particular, over the Hamiltonian quaternion algebra.
متن کاملReliability of astrophysical jet simulations in 2 D On inter - code reliability and numerical convergence
In the present paper, we examine the convergence behavior and inter-code reliability of astrophysical jet simulations in axial symmetry. We consider both pure hydrodynamic jets and jets with a dynamically significant magnetic field. The setups were chosen to match the setups of two other publications, and recomputed with the MHD code NIRVANA. We show that NIRVANA and the two other codes give co...
متن کاملNUMERICAL SIMULATIONS OF THE PHASE TRANSITIONS IN CLUSTERS
We have studied the phase transitions in atomic clusters by molecular dynamics simulation, assuming Lennard-Jones interatomic pair potential. Calculations are performed by DAP parallel computer. The results are analyzed by simulating their orientational distribution plots (dot-plot), and neutron diffraction patterns. It is shown that all the main features of the bulk phase transitions are e...
متن کاملHow Reliable Are Computer Simulations for RF Power Deposition? An Experimental Verification of Numerical Simulations
INTRODUCTION Numerical simulation methods, mainly Time-Domain Finite-Difference (FDTD) and Finite Element Method (FEM), have been extensively used in the past decade to study B1 field distribution and RF safety, particularly for high field applications. The simulated B1 field and imaging characteristics are in good agreement with experimental measurements [1-4]. Although many simulations have c...
