Two cosmological models with non-phantom matter having the same expansion of the universe as phantom cosmologies are constructed. The first model is characterized by the evolving gravitational “constant” G and a dark energy component with a non-conserved energy-momentum tensor. The second model includes two interacting components, the dark energy component and the matter component. Closed form ...

objectives: the aims of this study were to investigate the association of mini-nutritional assessment and activities of daily living as well as examining mini nutritional assessment as a good prognostic tool ofactivities of daily living in elderly residents of nursing home. methods & materials: in a cross-sectional study, among 1200 recorded files, 247 subjects completed mini nutritional assess...

An analysis with a transferred hyperfine field has been performed on the spectra of $^{115}\mathrm{In}$ nuclear quadrupole resonance experiments heavy fermion superconductor ${\mathrm{Ce}}_{3}{\mathrm{PtIn}}_{11}$ exhibiting co-occurrence two successive antiferromagnetic orderings (${T}_{\mathrm{N}1}$ = 2.2 K and ${T}_{\mathrm{N}2}$ 2.0 K) followed by superconducting transition (${T}_{\mathrm{c...

Defect engineering plays an important role in tailoring the electronic transport properties of van der Waals materials. Methods reported so far mainly rely on $e\phantom{\rule{0}{0ex}}x\phantom{\rule{0.333em}{0ex}}s\phantom{\rule{0}{0ex}}i\phantom{\rule{0}{0ex}}t\phantom{\rule{0}{0ex}}u$ defect type and concentration, hindering realization new types device functionalities associated with engine...

background: the aim of this work was to establish how well gel dosimeters performed, as substitutes for brain tissue compared with standard phantom materials such as water, polymethyl-methacrylate (or pmma), a150 plastic and te- liquid phantom material for dosimetry of neutron beams in boron neutron capture therapy. materials and methods: thermal neutron fluence, photon dose and epithermal neut...

In this paper, mini-channel type evaporator which is new in mobile air conditioning (MAC) or automotive air conditioning (AAC) systems is thermally modeled. The performance of mini-channel evaporator is also compared with the laminated evaporator which is being currently used in automotive industries. The mini-channel evaporator was constructed of two rows of parallel flow mini-channel tubes...

The $R(1)$, $R(3)$, and $P(3)$ rovibrational transitions in the (2-0) overtone band of HD molecule are measured Doppler-free saturation using technique NICE-OHMS spectroscopy. For line, hitherto not observed saturation, we report a frequency $203\phantom{\rule{0.16em}{0ex}}821\phantom{\rule{0.16em}{0ex}}936\phantom{\rule{0.16em}{0ex}}805\phantom{\rule{0.16em}{0ex}}(60)$ kHz. dispersive line sha...

solar mini-dimmings can be detect in the extreme ultra-violet coronal eruptions. here, sequences of 171_a images taken by solar dynamic observatory/atmospheric imaging assembaly on 13 june 2010 are used. in this special day, both of coronal mass ejection and prominence were observed. the average velocities and accelerations of 500 mini-dimmings which were detected using on feature based classif...

BACKGROUND In integrated PET/MR hybrid imaging the evaluation of PET performance characteristics according to the NEMA standard NU 2-2007 is challenging because of incomplete MR-based attenuation correction (AC) for phantom imaging. In this study, a strategy for CT-based AC of the NEMA image quality (IQ) phantom is assessed. The method is systematically evaluated in NEMA IQ phantom measurements...
