from a mean success rate of 85% to 97% (see Fig.4e). We propose that this kind of velocity controller could be regulated in insects by a simple feedback control loop. This loop changes the agent’s velocity inversely proportional to the global OF integrated by a subset of neurons (see...
Additionally, the group mean hit rates, false alarm rates and the sensitivity index d′ are reported (Table 1). A non-parametric Friedman test revealed a statistically significant difference in task performance between differing AMDs (Χ2(5) = 55.03, p-value<.001). Post-hoc analysis with ...
The theoretical foundation for this pricing scheme is a set of optimality conditions for integer programs. From this foundation, a column generation strategy is developed for finding columns that are likely to be of use in high-quality primal feasible solutions for the original problem. The ...
Note that each frequency table only contains a handful of outliers for which |z| ≥ 3.29. We'll now exclude these values from all data analyses and editing with the syntax below. For a detailed explanation of these steps, see Excluding Outliers from Data....
Structural defects control the kinetic, thermodynamic and mechanical properties of glasses. For instance, rare quantum tunneling two-level systems (TLS) govern the physics of glasses at very low temperature. Due to their extremely low density, it is very
trait analysis CH Llewellyn1,2,3, M Trzaskowski2,3, R Plomin2 and J Wardle1 Known single-nucleotide polymorphisms (SNPs) explain o2% of the variation in body mass index (BMI) despite the evidence of 450% heritability from twin and family studies, a phenomenon termed 'missing heritability'...
A gear-type effect was also detected: birds were more abundant on floating cages (mean = 47.9/100 m 2 of exposed area, S.E. = 5.8) than on floating bags (mean = 32.8/100 m 2 , S.E. = 1.9). The survey was followed by two experiments designed to test the effects of gear ...
