Shielding resources for four common radiopharmaceuticals utilized for imaging and therapy: Tc‐99m, F‐18, I‐131, and Lu‐177

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Introduction The use of radioactive materials in the United States has been tightly regulated by the Nuclear Regulatory Commission and other entities for many decades. In 2015, however, the Joint Commission began to require hospital‐based nuclear medicine departments to conduct shielding designs and evaluations for radioactive material areas ...

Unsupervised non‐small cell lung cancer tumor segmentation using cycled generative adversarial network with similarity‐based discriminator

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Background Tumor segmentation is crucial for lung disease diagnosis and treatment. Most existing deep learning‐based automatic segmentation methods rely on manually annotated data for network training. Purpose This study aims to develop an unsupervised tumor segmentation network smic‐GAN by using a similarity‐driven generative adversarial ...

Decay for thermoelastic laminated beam with nonlinear delay and nonlinear structural damping

AIMS Mathematics
This paper discussed the decay of a thermoelastic laminated beam subjected to nonlinear delay and nonlinear structural damping. We provided explicit and general energy decay rates of the solution by imposing suitable conditions on both weight delay and ...

General decay for a viscoelastic wave equation with strong time-dependent delay

Boundary Value Problems, 2017
A viscoelastic wave equation with strong damping and strong time-dependent delay in the internal feedback is considered. Under the assumption | μ 2 | < 1 − d μ 1 $|\mu_{2}|

Various Decays of Particles, Universal Decay Formulas and Their Possible Dynamic Basis and Applications [PDF]

arXiv, 2010
The decay modes and fractions in particle physics are some quantitative and very complex questions. Various decays of particles and some known decay formulas are discussed. Many important decays of particles and some known decays of resonances can be generally described by the square of some types of the associated Legendre functions.

Heterozygous variants in AP4S1 are not associated with a neurological phenotype

Annals of Clinical and Translational Neurology, EarlyView.
Abstract Biallelic loss‐of‐function variants in AP4S1 cause childhood‐onset hereditary spastic paraplegia. A recent report suggested that heterozygous AP4S1 variants lead to a syndrome of lower limb spasticity and dysregulation of sphincter function. We critically evaluate this claim against clinical observations in 28 heterozygous carriers of the same

A general decay and optimal decay result in a heat system with a viscoelastic term [PDF]

arXiv, 2018
We consider a quasilinear heat system in the presence of an integral term and establish a general and optimal decay result from which improves and generalizes several stability results in the literature.

Cerebral Amyloid Angiopathy Is Associated With Higher R2 Relaxation Rate: An MRI and Pathology Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Cerebral amyloid angiopathy (CAA) involves β‐amyloid deposition in the walls of cortical and leptomeningeal small vessels. Transverse relaxation rate (R2) is a major source of contrast in MRI. This study tested the hypothesis that CAA is associated with R2, extracted the spatial pattern of CAA‐related R2 abnormalities, and evaluated ...

General decay of solutions of a thermoelastic Bresse system with viscoelastic boundary conditions

Boletim da Sociedade Paranaense de Matemática, 2020
In this paper we consider a multidimensional thermoviscoelastic system of Bresse type where the heat conduction is given by Green and Naghdi theories. For a wider class of relaxation functions, We show that the dissipation produced by the memory eect is
