The redshifted 21-cm line of hydrogen holds great potential for the study of cosmology, as it can probe otherwise unobservable cosmic epochs. In particular, measurements of the 21-cm power spectrum during cosmic dawn---the era when the first stars were formed---will provide us with a wealt...
Age was also chosen as a stratification factor due to older adults typically having less comfort with technology [43], which is pertinent to the interventions under investigation. Concealment mechanism {16b} The allocation table was prepared by an independent statistician not involved in the study. ...
Second, the time point ranges of within 5 days for early and from day 10 for late tracheostomy were chosen based on earlier studies, a formal survey among German and US neurointensivists, and as to what was considered reasonable standards of care, yet with enough difference between the ...
survey respondents within countries or, for longitudinal surveys, survey answers per subject. Simply ignoring this structure will likely lead to spuriously low standard errors, i.e. a misleadingly precise estimate of our coefficients. This in turn leads to overly-narrow confidence...
ranges as well as pop-up notifications confirming that decline to answer responses are not data entry errors [44,45]. After data are synced to the server, a team member assigned to the task reviews the entire REDCap data record for completeness. Regular reports are run on the data to ...
about the infant’s feeding status, at two timepoints. F1 is at 36 weeks’ post-menstrual age (PMA; 4 weeks before the estimated date of delivery—the EDD—which defines 40 weeks of gestation) and F2 is at 18 weeks after the EDD—their SMS response automatically completes a CRF for ...
(www.clevr.net), which allows for a fine-tuning and individualization of the therapy; that is for example by varying the number of avatars situated in the virtual social environment chosen from a large catalog of avatars with different features as age, gender, clothing and ethnicity and ...
reported in Supplementary Table3. We allow the lightcurve fit parameters to vary within the rangesx1 = [−3.0, 3.0], c = [−0.3, 0.3], but assume them to be the same for all four images. This is an excellent approximation in the absence of appreciable differential re...
Surveys of soil properties related to soil functioning for many regions of Kyrgyzstan are limited. This study established ranges of chemical (soil organic matter (SOM), pH and total N (TN)), physical (soil texture), and biochemical (six ... Z Sakbaeva,Veronica Acosta-Martinez,J Moore-Kucera...
This report endorses no technology for driving LED lamps. Specifically, Section III of the report gives tutorial surveys on health effects of flicker. Section IV introduces a few typical LED driving methods that introduce flicker in frequency ranges of interest. III. FLICKER The health effects of...
