Quantifying spectral information about source separation in multisource odour plumes.

Odours released by objects in natural environments can contain information about their spatial locations. In particular, the correlation of odour concentration timeseries produced by two spatially separated sources contains information about the distance between the sources. For example, mice are able to distinguish correlated and anti-correlated odour fluctuations at frequencies up to 40 Hz, while insect olfactory receptor neurons can resolve fluctuations exceeding 100 Hz.

Repair of Microperforate Hymen.

Objective: Subocclusive variants of the hymen are a group of hymenal anomalies that result due to a failure of canalization of the urogenital sinus. One of these variations is the microperforate hymen, for which accurate incidence is unknown. Microperforate hymen is a non-obstructing variation that allows for menstrual egress and often patients present due to inability to use a tampon.

Effects of magnetically treated water on the survival of bacteria in biofilms.

The goal of this study was to evaluate if a magnetic water treatment device could be used to mitigate biofilms in water systems. Magnetic treatment was applied to water upstream of a modified Robbins device in which biofilms were formed. Duration of magnetic treatment, system flow rate, and field strength were varied to assess the impacts on the biofilm.

Toward the validation of crowdsourced experiments for lightness perception.

Crowdsource platforms have been used to study a range of perceptual stimuli such as the graphical perception of scatterplots and various aspects of human color perception. Given the lack of control over a crowdsourced participant's experimental setup, there are valid concerns on the use of crowdsourcing for color studies as the perception of the stimuli is highly dependent on the stimulus presentation. Here, we propose that the error due to a crowdsourced experimental design can be effectively averaged out because the crowdsourced experiment can be accommodated by the Thurstonian model as the convolution of two normal distributions, one that is perceptual in nature and one that captures the error due to variability in stimulus presentation.

Concurrent processing of the prosodic hierarchy is supported by cortical entrainment and phase-amplitude coupling.

Models of phonology posit a hierarchy of prosodic units that is relatively independent from syntactic structure, requiring its own parsing. It remains unexplored how this prosodic hierarchy is represented in the brain. We investigated this foundational question by means of an electroencephalography (EEG) study.
