between three sleep variables [sleep quality (r = 0.096), duration (r = 0.069), and sleepiness (r = -0.133)] and school performance, especially in boys. Yet, Brown et al. [22], analysing risky behaviours in a sample of 13,677 American adolescents in grades 9 through 12,...
Since lymph is recognized as a transport vehicle for enzymes, the lymph–serum ratio of enzyme activity is useful in estimating the origin and fate of a particular enzyme in lymph and serum. Methods usually applied to serum are applicable to measuring enzyme activity in lymph. The diagnostic ...
Nanoscale activity-dependent remodelling of F-actin revealed by STED nanoscopy. Three color imaging of F-actin (STED, white), phosphorylated neurofilaments (confocal, cyan) and MAP2 (confocal, yellow) was performed to identify F-actin nanostructures in dendrites (yellow) and axons (cyan). STED ...
Here, each adamantine was coarse-grained into a trihedron structure with a mapping ratio of ~3:1, and each core Ag atom was mapped to one CG bead. During the simulations of the interaction between AgNMs and the bacterial membrane, the system was equilibrated at zero tension using the NPT ...
SSCS consists of 11 items, including 6 measuring trait-like creative self-efficacy (tCSE; e.g., “I am good at proposing original solutions to problems”), and 5 measuring creative personal identity (CPI; e.g., “My creativity is important for who I am”). Participants rated items using...
ML can poten- tially be an excellent tool for solving many traditional problems related to the research of physical activity, sedentary, and sleep behaviors such as activity recognition, posture detection, profile analysis, and correlates research. How- ever, despite this ...
Atrial fibrillation disorders are one of the main arrhythmias of the elderly. The atrial and ventricular activities are decoupled during an atrial fibrillation episode, and very rapid and irregular waves replace the usual atrial P-wave in a normal sinus
Unfortunately, sensitivity and reproducibility of the radiometric method are low [7, 29]. To overcome these problems, a spectrophotometric assay has been developed to allow a more accurate estimation of MCM kinetic parameters [7, 8] however, spectrophotometric methods are more appropriate for studying...
The ratio of IC50 values for the WT vs. the mutant are shown in Fig. 3c and reflects the importance of the specific contact; the log of the value is used to aid in visualization. The Ser269Ala mutation had relatively little effect, and the Phe134Leu mutant, which eliminated a predicted...
The RC is determined as the ratio of the measured activity concentration of an object to the true concentration. (2)RC=ConmeasuredContrue The computing of the RC depends on the object size and also on the PSF system. This method supposes that the activity in the ROI must be uniform and ...
