Here are some free short stories to read online. These very short stories are perfect for high school or middle school students or anyone who loves reading.
The composite line resulting from experiments with a fixed resonance sample placed in front of a resonance detector has been studied. An "inversion" of the composite line at high effective thicknesses of the sample has been observed. The parameter asymmetry of the composite line which is a very...
First, one intends to prove that very simple models with sufficient accuracy can be identified for a given location. These models have to obey the current users exigencies (i.e. to evaluate “instantaneous” global irradiance). Second, one studies the dependence of their accuracy on different ...
Methods In the Umeå85 + /GErontological Regional DAtabase (GERDA) study, 387 participants were assessed with both the GDS-15 and the Montgomery-Åsberg Depression Rating Scale (MADRS). The mean age was 91 years. Concurrent validity between the scales was calculated using Spearman's corre...
In this paper, we present a novel low-frequency sensing solution based on the manipulation of the near-field distribution by employing a passive holographic magnetic metasurface, excited by an active RF coil placed in its reactive region. In particular,
For the majority of experiments, we used the validation set as the test set. Certain experiments were also carried out on the test set and submitted to the official ILSVRC server as a “VGG” team entry to the ILSVRC-2014 competition (Russakovsky et al., 2014). ...
Samples for DPH anisotropy experiments were composed of 100% VLC-SL or PSM: VLC-SL (1:1, molar ratio) with DPH added at 0.5 mol%. The G factor was determined at 10 °C prior to each measurement and the samples were then scanned at a rate of 2 °C/min. 2.4.2. Fluorescence quench...
Methods Participants Fourteen participants (six men, eight women, aged between 19 and 29 years, mean age 21.1, SD 2.4) were recruited from the Daegu Gyeongbuk Institute of Science and Technology. Among them, 13 participants were included in this study, because the data of one male participant...
