Two-stage sampling plans in which the estimator is computed from the second sample only, and has a guaranteed precision irrespective of the parameter value, are considered. We prove the following optimality property for existing strategies in binomial and Poisson populations: there exists no other ...

The methods for solving the class imbalance task can generally be divided into two categories: sampling approaches and algorithmic approaches. The sampling approach is factually a re-sizing procedure to balance the given imbalance dataset. The algorithmic approach can be viewed as a procedure to adju...
Integral Methods for Two-Phase Flow in Hydraulic Systems I Importance of Two-Phase Flow A phase is a system, or a portion of a system, composed of any number of chemical constituents that is homogeneous and has a definite boundary [43]. Multiphase flows are flows of mixtures of two or mo...
T cell development in the thymus is essential for cellular immunity and depends on the organotypic thymic epithelial microenvironment. In comparison with other organs, the size and cellular composition of the thymus are unusually dynamic, as exemplified
In early sensory systems, cell-type diversity generally increases from the periphery into the brain, resulting in a greater heterogeneity of responses to the same stimuli. Surround suppression is a canonical visual computation that begins within the reti
For closer thresholds, it will not take as long to accumulate the necessary amount of information; consequently, RTs will be faster. However, the probability that erroneous in- formation causes the system to reach threshold will be larger, producing a higher error rate. Sequential sampling models...
These methods achieve high power against different types of signals. Driven by the above two concerns of the test (Cai et al., 2014), we reconsider the problem of testing two mean vectors under sparse alternatives. We propose a new test based on the prepivoting approach. The concept of ...
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 ...
