Quantitative analysis can potentially improve the accuracy and consistency of 2-18F-fluoro-2deoxy-D-glucose (18F-FDG) positron emission tomography (PET), particularly for the assessment of tumor response to treatment. Although not without limitations, standardized uptake value (SUV) has emerged as the predominant metric for tumor quantification with 18F-FDG PET. Growing literature suggests that...
In recent years, wireless charging technology has provided an alternative to charging equipment. Wireless charging technology has already proved to be useful in our daily lives in phones, buses, restaurants, etc. Wireless charging technology can also be applied in energy-bounded wireless sensor networks (WSNs), and these are called wireless rechargeable sensor networks (WRSNs). The optimized ch...
BACKGROUND Dynamic contrast-enhanced MRI (DCE-MRI) biomarkers have proven utility in tumors in evaluating microvascular perfusion and permeability, but it is unclear whether measurements made in different centers are comparable due to methodological differences. PURPOSE To evaluate how commonly utilized analytical methods for DCE-MRI biomarkers affect both the absolute parameter values and re...
1. The main purpose of this paper is to show that certain properties of a metrizable space, such as local connectedness or local contractibility or LCn or local compactness, hold uniformly with a properly chosen metric.2 This result, while easy to prove, seems to be new, and often permits simplifications in proofs dealing with various kinds of local connectedness. In §2, we obtain an analogous ...
Free-roaming domestic cats are a major anthropogenic source of morbidity and mortality to wild birds and mammals in the United States. Permitted wildlife rehabilitators routinely treat cat-caused injuries. However, extent of these activities is under-reported in the scientific literature. To determine incidence, age class, mortality, diversity and frequency of species affected, nature of injuri...
Pharmacokinetic analysis of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) time-course data allows estimation of quantitative parameters such as K (trans) (rate constant for plasma/interstitium contrast agent transfer), v e (extravascular extracellular volume fraction), and v p (plasma volume fraction). A plethora of factors in DCE-MRI data acquisition and analysis can affect ac...
In this article we propose contextual deontic logic (CDL). Contextual obligations are written as O( j n ), and are to be read as ‘ should be the case if is the case, unless is the case’. The unless clause is analogous to the justification in Reiter’s default rules. We show how contextual obligations can be used to solve certain aspects of contrary-to-duty paradoxes of dyadic deontic logic. 1 Co...
