Background and purpose: Radiation therapy treatment planning is a manual, time-consuming task that might be accelerated using machine learning algorithms. In this study, we aimed to evaluate if a triplet-based deep learning model can predict volumetric modulated arc therapy (VMAT) dose distributions for prostate cancer patients. Materials and methods: A modified U-Net was trained on triplets, a co
Alternative reproductive tactics (ARTs) often exhibit more than one mating behavior depending on social context (i.e., behavioral plasticity). It has been hypothesized that by constraining an ART from reaching optimal morphological states, intralocus tactical conflict could promote the maintenance of behavioral plasticity in ARTs, rather than the use of a fixed mating behavior to match an optimal
The density and modulus of elasticity (MOE) distribution can provide information on the effectiveness of parametric and non-parametric methods in calculating the characteristic value of MOE. In this study, we aim to determine the optimal distribution model of the actual measured data of the lumber. We also estimate the lumber’s MOE characteristic value and compare the difference in density and MOE
Self-consistent field ab initio calculations using a previously published, optimized basis set [J. Chem. Phys. 94 (1991) 6677] and second-order Møller-Plesset (MP2) perturbation theory are used in a study of the ArHCl intermolecular potential. The ab initio results are compared to the recently published H6(4, 3, 0) potential-energy surface [J. Phys. Chem. 96 (1992) 4237]. Good agreement is obtaine
Purpose: Individuals with tetraplegia depend on alternative interfaces in order to control computers and other electronic equipment. Current interfaces are often limited in the number of available control commands, and may compromise the social identity of an individual due to their undesirable appearance. The purpose of this study was to implement an alternative computer interface, which was full
The rapidly growing interest in photocatalytic systems for direct solar fuel production such as hydrogen generation from water splitting is grounded in the unique opportunity to achieve charge separation in molecular systems provided by electron transfer processes. In general, both photoinduced and catalytic processes involve complicated dynamics that depend on both structural and electronic effec
This article identifies factors which contribute to households’ willingness to pay for improving and protecting a multiple-use water scheme in Ethiopia. It does so through descriptive statistics, a probit model and contingent valuation methods complemented with qualitative data. Estimates suggest farmers’ willingness to pay is based on gender, the prevalence of waterborne disease, the time to coll
The implementation of global anti-doping regulations was intended to provide a level playing field for all athletes entering sports competitions. However, studies have shown that the worldwide harmonization of rules has not been entirely efficacious. For instance, great variation has been found in how anti-doping organizations implement anti-doping regulations, and it has also been shown that athl
This paper presents a novel approach for the elaboration of an integration strategy for controls and computing systems at large particle accelerator based research facilities. The approach is applied in a specific case study conducted at the world-leading neutron science facility European Spallation Source (ESS). First, an introduction to the term 'integration' in the Systems Engineering literatur
OBJECTIVE: Sleep disturbances and alterations of diurnal endocrine rhythms are associated with increased risk of type 2 diabetes (T2D). We previously showed that young men born small for gestational age (SGA) and with increased risk of T2D have elevated fat and decreased glucose oxidation rates during nighttime. In this study, we investigated whether SGA men have an altered diurnal profile of horm
In 2014 the Nordic Council of Ministers initiated a new bioeconomy project: “Test centers for green energy solutions – Biorefineries and Business needs”. The purpose was to strengthen green growth in the area of the bioeconomy by analyzing and mapping the current status of the bioeconomy in the Nordic countries and identify potentials and obstacles, needs and opportunities. Based on this a set of
Conditional knockout mice are commonly used to study the function of specific genes in hematopoiesis. Different promoters that drive Cre expression have been utilized, with the interferon-inducible Mx1-Cre still being the most commonly used “deleter strain” in experimental hematology. However, different pitfalls associated with this system could lead to misinterpretation in functional studies. We
Background and Aims: Small-bowel bleeding is the primary indication for capsule endoscopy (CE). Many experts advocate a "watch-and-wait" policy in negative CE. This meta-analysis examines the odds of rebleeding after negative index CE and the impact on long-term follow-up. Methods: A comprehensive literature search identified articles examining the rebleeding rate after negative CE. Demographic an
Water exchange on Pt(H20)42+ and trans-PtCI2(H20)2 has been studied by means of a new oxygen18 tracing technique. The exchange between a platinum(II) complex and 018-enriched water has been rapidly quenched by addition of excess chlorine, which gives a substitution-inert platinum(IV) complex. The time-dependent oxygen16/oxygen18 distributions of the platinum(II) complexes are obtained from the 195
Under climate change conditions, climatic wildfire danger could also increase in ecosystems not dominated by fires until now. This increasing trend could lead to more area burned in the future. We have developed an algorithm to map new fire-prone areas in Europe and Northern Africa that identifies grid points where a rare fire event is becoming the mean at the end of the 21st century. When applyin
Research has shown that people with psychiatric disabilities who attend a day center rate their satisfaction with daily occupations equally in comparison with non-attendees. The current study investigates which occupations the target group performs and also differences in occupational choices between attendees and non-attendees. Reported occupations were analyzed with content analysis. Day center
