Physiological Responses to Aversive and Non-aversive Audiovisual, Audio, and Visual Stimuli.

We examined differences in physiological responses to aversive and non-aversive naturalistic audiovisual stimuli and their auditory and visual components within the same experiment. We recorded five physiological measures that have been shown to be sensitive to affect: electrocardiogram, electromyography (EMG) for zygomaticus major and corrugator supercilii muscles, electrodermal activity (EDA), and skin temperature. Valence and arousal ratings confirmed that aversive stimuli were more negative in valence and higher in arousal than non-aversive stimuli.

Thermally and Base-Triggered "Debond-on-Demand" Chain-Extended Polyurethane Adhesives.

A series of novel chain-extended polyurethanes (CEPUs) featuring degradable sulfonyl ethyl urethane chain-extenders that permit degradation under base-triggered conditions to afford "debond-on-demand" elastomeric adhesives are reported. Exposure of the CEPUs to -butylammonium fluoride (TBAF) triggered the degradation of the sulfonyl ethyl urethane chain-extenders. Lap shear adhesion tests of the CEPUs exposed to TBAF revealed reductions in shear strength of up to 65% for both aluminum and glass substrates, from 2.

Bone and Nerve Response to Sciatic Compression Neuropathy in a Rabbit Model.

Compression neuropathy is a prevalent medical condition, including common types such as carpal tunnel syndrome, cubital tunnel syndrome, sciatica, and many others. While the neurological consequences are well understood, the effects on bone properties and the potential downstream impact on fracture risk remain less clear. This study aimed to assess the influence of compressive neuropathy on bone properties using a rabbit model of sciatic nerve compression.

Exploring Demographic Disparities in Private Well Water Testing in North Carolina.

The natural, built, and social environments shape drinking water quality supplied by private wells. However, the combined effects of these factors are not well understood. Using North Carolina as a case study, we (i) estimate the demographic characteristics of the private well population; (ii) evaluate representation in well testing records; and (iii) demonstrate how spatial scale influences knowledge of well-using household demographics and representation in testing.
