Early Interactive Acoustic Experience with Non-speech Generalizes to Speech and Confers a Syllabic Processing Advantage at 9 Months.

During early development, the infant brain is highly plastic and sensory experiences modulate emerging cortical maps, enhancing processing efficiency as infants set up key linguistic precursors. Early interactive acoustic experience (IAE) with spectrotemporally-modulated non-speech has been shown to facilitate optimal acoustic processing and generalizes to novel non-speech sounds at 7-months-of-age. Here we demonstrate that effects of non-speech IAE endure well beyond the immediate training period and robus...

GfaViz: Flexible and interactive visualization of GFA sequence graphs.

The Graphical Fragment Assembly (GFA) formats are emerging standard formats for the representation of sequence graphs. While GFA 1 was primarely targeting assembly graphs, the newer GFA 2 format introduces several features, which makes it suitable for representing other kinds of information, such as scaffolding graphs, variation graphs, alignment graphs, and colored metagenomic graphs. Here, we present GfaViz, an interactive graphical tool for the visualization of sequence graphs in GFA format. The software...

Firefly: Virtual Illumination Drones for Interactive Visualization.

Light specification in three dimensional scenes is a complex problem and several approaches have been presented that aim to automate this process. However, there are many scenarios where a static light setup is insufficient, as the scene content and camera position may change. Simultaneous manual control over the camera and light position imposes a high cognitive load on the user. To address this challenge, we introduce a novel approach for automatic scene illumination with Fireflies. Fireflies are intellig...

Aggregation-Induced Emission for Visualization in Material Science.

Fluorescent imaging techniques have attracted much attention as a powerful tool to realize the visualization of the structural and morphological evolutions for the various materials. However, the traditional fluorescent dyes usually suffered from the aggregation-caused quenching effect that severely limited the visualization results. In contrast, aggregation-induced emission (AIE) molecules with high quantum yields in the condensed state showed great opportunities in the imaging technique. In this feature a...

Stimulus dynamics-dependent information transfer of olfactory and vomeronasal sensory neurons in mice.

The parallel processing of chemical signals by the main olfactory system and the vomeronasal system has been known to control animal behavior. The physiological significance of peripheral parallel pathways consisting of olfactory sensory neurons and vomeronasal sensory neurons is not well understood. Here, we show complementary characteristics of the information transfer of the olfactory sensory neurons and vomeronasal sensory neurons. A difference in excitability between the sensory neurons was revealed by...

BioNetApp: An interactive visual data analysis platform for molecular expressions.

An ongoing challenge is to provide better tools that can mine data patterns that could not have been discovered through simple visualization. Such mining capabilities also need to be coupled with intuitive visualization to portray those fi...

Whose Risk? Why Did the U.S. Public Ignore Information About the Ebola Outbreak?

To test a possible boundary condition for the risk information seeking and processing (RISP) model, this study experimentally manipulates risk perception related to the 2014 Ebola outbreak in a nationally representative sample. Multiple-group structural equation modeling results indicate that psychological distance was negatively related to systematic processing in the high-risk condition. In the low-risk condition, psychological distance was positively related to heuristic processing; negative attitude tow...
