It is so interesting how math and science can sometimes go hand-in-hand. When it comes to research or experimentation, it is important to have mathematical concepts to explain how the process occurred. Answer and Explanation: A quantitative variable is a quantity that is described using numerical...
Deterministic model – in a deterministic model,given the input data and parameter values, the model determines exactly the output, such that we always get the same result. ... The stochastic model is simply the error in our ability to predict the outcome (dependent variable) for a particular...
Male reproductive system ageing is closely associated with deficiency in testosterone production due to loss of functional Leydig cells, which are differentiated from stem Leydig cells (SLCs). However, the relationship between SLC differentiation and age
Genome-wide expression profiling identified five biological BC subtypes36, namely luminal A/B, HER2-enriched, basal-like and normal breast-like, which differ by hormonal receptor status, proliferation, genomic instability, mutational signatures, treatment response and prognosis37,38,39,40,41. It has...
Define the following terms and, briefly, explain how they relate to experimental design: independent variable, dependent variable, experimental group, control group. What is the distinction between the terms "experimental set-up" and "control set-up" in biology? What is meant b...

Presently, such an approach is often cost prohibitive as compared with targeting a single variable region. To generate full-length high-quality reads, sequencing with the Pacific Biosciences RSII instrument is required at a cost per read that is much higher than sequencing smaller regions such as...
is known, the occurrence of QT prolongation can be qualitatively compared, but predicting the magnitude of change from either Guinea pig or dog pre-clinical studies is variable. For example, dogs have been found to be approximately 2.5 times less sensitive to QT prolongation in terms of the ...

those features that did not have a meaningful effect on the dependent variable or prediction of output. Then, we deployed exhaustive feature selection, which aims at finding the best-performing feature subset by searching across all possible feature combinations (a brute-force method) until the desi...
