background: anxiety among patients after surgery can affect their physiological and psychological well-being. the aim of this study was to investigate and compare the effects of benson’s relaxation and rhythmic breathing techniques on postoperative anxiety in candidates for the mastectomy surgery. methods: this randomized controlled clinical trial study was conducted with ninety patients in 201...

We propose a multiple relaxation time entropic realization of two-phase flow lattice Boltzmann model we introduced in earlier works arXiv:2112.01975 S.A. Hosseini, B. Dorschner, and I. V. Karlin, arXiv preprint, (2021). While the original with single allows us to reach large density ratios, it is limited terms stability respect non-dimensional viscosity Courant--Friedrichs--Lewy number. Here sh...

The traditional multi-level grid multiple-relaxation-time lattice Boltzmann method (MRT-LBM) requires interpolation calculations in time and space. It is a complex computationally intensive process. By using the buffer technique, this paper proposes new MRT-LBM which only spatial calculations. proposed uses center point format to store information. type determination flow field calculation doma...

Local deviations of the main field and signal decay due to transverse relaxation lead to perturbations of the Fourier encoding commonly applied in magnetic resonance imaging. Hence, images acquired with trajectories having long readout times suffer from artefacts such as blurring, geometric distortion, and intensity inhomogeneity. These effects can be corrected by means of iterative reconstruct...

We present a multi-level probabilistic relaxation scheme appropriate for image segmentation on the basis of features computed at various resolution levels. At each level, we incorporate contextual information computed from the features in the coarser scale representation of the scene, as well as information from the features computed in the ner scale representation, until a full segmentation is...

Recently, Chan et al. (2000) proposed an efficient heuristic for a class of finite time planning horizon single-warehouse multi-retailer system with complex (nonlinear) transportation cost structures. Their heuristic is based on solving a large LP relaxation of the underlying problem. In this paper, we analyze the strength of the proposed LP relaxation and show that it attains the best theoreti...

after springs production, different residual stresses are created in the inner and outer surfaces of spring wires. some of these stresses for example compressive residual stresses are useful and some are harmful. the effects of vareation of these stresses are caused spring relaxation and decrising in their free length when they are loaded intermittently. for review this phenomena in this resear...

introduction: nano-indentation has recently been employed as a powerful tool for determining the mechanical properties of biological tissues on nano and micro scales. a majority of soft biological tissues such as ligaments and tendons exhibit viscoelastic or time-dependent behaviors. the constitutive characterization of soft tissues is among very important subjects in clinical medicine and espe...
