Objectives: The purpose of this investigation was to compare three test methods for isolating the test ear for children with single-sided deafness (SSD) who use a cochlear implant (CI).
Methods: Word recognition was assessed for five CI recipients with SSD and six bilateral CI recipients with no acoustic hearing. For the SSD subjects, performance was compared: 1) in the sound field with masking in the normal-hearing ear, 2) in the sound field with an earplug and earmuff ("plug-and-muff"), and 3) via direct connect (DC).

Background: The animal model is a key tool in quantitative genetics and has been used extensively to estimate fundamental parameters, such as additive genetic variance or heritability. An implicit assumption of animal models is that all founder individuals derive from a single population. This assumption is commonly violated, for instance in crossbred livestock or when a meta-population is split into genetically differentiated subpopulations.

Simulations are important for understanding complex reactions, but their interpretation is challenging owing to the large number of degrees of freedom typically involved. To address this issue, various means for relating the dynamics of a stochastic system to its structural and energetic features have been introduced. Here, we show how two leading approaches can be combined to advantage.

The conformational space of a 20-residue three-stranded antiparallel beta-sheet peptide (double hairpin) was sampled by equilibrium folding/unfolding molecular dynamics simulations for a total of 20 micros. The resulting one-dimensional free-energy profiles (FEPs) provide a detailed description of the free-energy basins and barriers for the folding reaction. The similarity of the FEPs obtained using the probability of folding before unfolding (pfold) or the mean first passage time supports the robustness of the procedure.

Many complex networks have an underlying modular structure, i.e., structural subunits (communities or clusters) characterized by highly interconnected nodes.
