We postulate that the brain response to insulin adapts to short-term changes in diet before weight gain and may facilitate the development of obesity and associated diseases. The small sample size of our study limits the generatability of our results and may be the reason why we did not ...
ANSWER: True TYPE: TF DIFFICULTY: Easy KEYWORDS: confidence interval, mean, standard deviation unknown 7. The tdistribution a) assumes the population is normally distributed. b) approaches the normal distribution as the sample size increases. c) has more area in the tails than does the normal ...
together, a small training sample size may exaggerate the accuracy of ML due to overfitting or random effects, whereas large-scale studies require more financial resources and consume more time [7,12,13]. Therefore, an adequate sample size is required for a reliable and efficient outcome of a...
In this way, we have a large negative sample size (crucial for CL) while using a relatively small batch size (to reduce GPU memory footprint). On the contrary, both CLIP and ALIGN use negative samples within each training batch, requiring a large batch size (i.e., a great demand for...
has 555 variants across 53 (52 COSMIC tier 1) genes [8]. As useful as each of these reference samples are, even if both are used in panel testing validation, only 127 out of the 576 COSMIC Tier1 genes will have at least one variant in either panel and only 53 genes would have any...

To do this, we built an algorithm using a single parameter x to control the sampling rate across K clusters of size NK, where x is the approximate sample size to take from each cluster K. Iteratively, our algorithm randomly sampled cells from each donor in each cluster K without ...
The discharge process has undergone major changes in many river basins throughout the world as a result of the simultaneous influences of global climate change and human activity. Flow duration curves (FDCs) are crucial indicators of river basins’ hydrological processes. However, it is challenging...
