Joint EANM-SNMMI guideline on the role of 2-[¹⁸F]FDG PET/CT in no special type breast cancer: (endorsed by the ACR, ESSO, ESTRO, EUSOBI/ESR, and EUSOMA)

Introduction: There is much literature about the role of 2-[¹⁸F]FDG PET/CT in patients with breast cancer (BC). However, there exists no international guideline with involvement of the nuclear medicine societies about this subject. Purpose: To provide an organized, international, state-of-the-art, and multidisciplinary guideline,...

The current role of nuclear medicine in breast cancer

Breast cancer is the most common cancer in females worldwide. Nuclear medicine plays an important role in patient management, not only in initial staging, but also during follow-up. Radiopharmaceuticals to study breast cancer have been used for over 50 years, and several of these are still used in clinical practice, according to the most...

CFD code comparison, verification and validation for decay tests of a FOWT semi-submersible floater

With the advancement of high-performance computation capabilities in recent years, high-fidelity modelling tools such as computational fluid dynamics are becoming increasingly popular in the offshore renewable sector. To justify the credibility of the numerical simulations, thorough verification and validation is essential. In this work,...

The Development of a Partially Averaged Navier-Stokes KSKL Model

A new partially averaged Navier-Stokes (PANS) closure is derived based on the k-kL (KSKL) model. The aim of this new model is to incorporate the desirable features of the KSKL model, compared to the k-ω shear stress transport model, into the PANS framework. These features include reduced eddy-viscosity levels, a lower dependency on the cell...

Code Verification of Non-Newtonian Fluid Solvers for Single- and Two-Phase Laminar Flows

The presence of complex fluids in nature and industrial applications combined with the rapid growth of computer power over the past decades has led to an increasing number of numerical studies of non-Newtonian flows. In most cases, non-Newtonian models can be implemented in existing Newtonian solvers by relatively simple modifications of the...

On the use of synthetic inflow turbulence for scale-resolving simulations of wetted and cavitating flows

The Delft Twist 11 Hydrofoil is a common test case for investigating the interaction between turbulence and cavitation modelling in computational fluid dynamics. Despite repeated investigations, results reported for the lift and drag coefficient are accompanied by significant uncertainties, both in experimental and numerical studies. When...

Evaluation of scale-resolving simulations for a turbulent channel flow

Different variable resolution turbulence modelling approaches (Hybrid, Bridging models and LES) are evaluated for turbulent channel flow at Re_τ=395, for cases using either streamwise periodic boundary conditions or a synthetic turbulence generator. The effect of iterative, statistical and discretisation errors is investigated. For...

On the accuracy of partially averaged Navier–Stokes resolution estimates

Partially Averaged Navier–Stokes computations can employ three different approaches for specifying the ratio of modelled-to-total turbulence kinetic energy f_k. Use can be made of either a constant, a spatially- or a spatially- and temporally-varying value. This work compares different estimates for f_k found in literature...

A sensitivity analysis of CFD transition modelling in the context of vortex roll-up prediction

A sensitivity analysis of the transitional flow over a NACA66₂ - 415 foil and the elliptical Arndt wing is carried out. The SST turbulence model is complemented with the ? - Re ^~_?t transition model to determine the effect of varying turbulence intensity and eddy-viscosity ratio on the integral quantities and...

Ultrafast demagnetization in iron: Separating effects by their nonlinearity

The laser-driven ultrafast demagnetization effect is one of the long-standing problems in solid-state physics. The time scale is given not only by the transfer of energy, but also by the transport of angular momentum away from the spin system. Through a double-pulse experiment resembling two-dimensional spectroscopy, we separate the different...

Análise do nível de abertura de dados governamentais de trânsito no brasil

The study aimed to identify the level of data openness of the state traffic departments in Brazil (DETRANs). Two assessment instruments were used: Berners-Lee’s (2010) Five Star Scheme and the 15 Open Data Principles proposed by Opengovdata (2007). Based on them, a methodology for structured analysis was built, and used to analyze three sets of...
