These types of writing were tested in the MCE Englishsubject Paper One. A case study which employs qualitative method using purposive sampling wascarried out to six students. The data were analysed in a descriptive form and errors made by thestudents were recorded into 300 frequencies. The ...
a, A delta-doped layer of14N (green) is grown on a diamond substrate. NV centres are created via local electron irradiation (orange beam) and subsequent high-temperature annealing.b, Schematic depiction of a two-dimensional layer of NV (red) and P1 (blue) centres. Dilute NV centres functi...
Method of sampling and collecting the microbes in soil and root-associated compartments (a) and workflow for implementation of machine learning models for predicting two rice cultivars (b). Full size image Results Cd accumulation features consistently differed between two rice cultivars with varied soil...
The variance components quantify two sources of uncertainty about point estimates, arising from distinct aspects of sampling error. The first source of sampling variance (W) quantifies complete-data uncertainty, which arises from the random process of sampling from a population, thus introducing ...
For the continuous recording of the breathing signal, we used a belt with a resistive strain gauge transducer positioned about a centimeter above the costal line. The sampling of ECG and breathing signals was performed with the same frequency of 1000 Hz. Filters were set according to the ...
When the industrial material flows into the pneumatic conveying system, the valve on the branch pipeline is opened for continuous sampling and testing during the contact between the industrial material and the GS-TENG surface. Fig. 8b illustrates the structure and working principle of GS-TENG, ...
With such an implementation, it is not the scalar but the frequency of sampling visits that changes over time, causing differences in discrimination performance. The biggest challenge is that when it comes to volumes and probabilities, no direct method of interrogating an animal’s estimate, and ...
The latter two sampling time points were selected for this study based on the data presented above. Most of these accessions were from different locations of Fertile Crescent region (Table S1), thus likely represented different genotypes. As an additional control, RNA-seq was also carried out ...
