For both methods, the samples were mounted inside a sealed, nitrogen-filled sample box. To analyse the data, we first subtracted the background and then normalized the data, as well as shifting the peak to position zero. Detailed instructions can be found in ref.15. Steady-state PL measurem...
A photon has a wave number of {eq}\displaystyle k = 4 \pi \times 10^6 \rm \frac{rad}{m} {/eq}. Calculate the wavelength {eq}\displaystyle \rm \lambda {/eq} of the photon. Wavelength: In physics, the wavelength is the distance between two...
cutadapt (v2.6) was employed within the QIIME 2 for demultiplexing of paired-end (PE) reads according to the barcode sequence of each sample, followed by the trimming of barcodes and primers. The demultiplexed sequences were then quality filtered to remove bases with quality...
Patterns of genetic differentiation among samples was explored by a preliminary non-model Principal Components Analysis74(PCA) in the SNP&Variant Suite v.8.0.1 (SVS, Golden Helix Inc., Bozeman, MT) using the 57k SNP panel set. Each sample was then reassigned to its population of origin runn...
Answer to: A photon has a wave number of \rm{k} = 7 \pi \times 10^6\ \rm{rad/m}. Calculate the angular frequency \omega, frequency f. and...
PI-3,4-P2 可直接激活 Akt, 而 PI-3,4,5-P3 可激活磷脂酰肌醇依赖性激酶-1(PDK-1),后者再使 Akt 的 Thr308 磷酸化,在 PDK-2 存在下,Akt 的 Ser 473 被磷酸化而完全被激活。mTOR 另一 条上游信号通道为 TSC1/2 通路,该路径主要通过 TSC1/2 与 mTOR 复合物来实 现。mTOR 复合物包括 Raptor...
This was a purposeful sample, with the criterion of a mixture of boys and girls, and who represented diversity in activity behaviours. Observations took place over a four-day period when the children were wearing the pedometers. On each observation day, two or three trained observers arrived ...
What is the magnitude of the amplitude of a spring-mass system where the angular frequency is 1 rad/s, and the mass is at 4 cm at 1 second? A chunk of metal is measured many times and is found to be 10.15(6) kg. 95% of future measurements will fall withi...
Recorded sample-value measurement delays on the communication bus were synchronized via the Precision Time Protocol (PTP) defined by the IEEE 1588 standard, thus avoiding a measured-value phase shift. Protection-function performance in a digital substation is very similar to classical substations, with...
The sample size and statistical power were calculated using G*Power 3.1. A sample size of 560 households was required to detect a small to medium effect in Cohen's f2 of 0.07 at one-tailed alpha of 0.05 and a statistical power of 95% with multiple regression and 35 predictor variables (...
