Maximum a posteriori underwater acoustic source localization based on time differences of arrival accounting for refraction.

Traditional underwater acoustic source localization methods based on time differences of arrival (TDOA) in the presence of refraction first estimate the source depth and range to each hydrophone and then estimate the horizontal location of the source. The accuracy of these methods is compromised by errors in range estimation. To address this, we propose a three-dimensional source localization method that utilizes TDOA measurements between direct and surface-reflected arrivals at N(N ≥3) hydrophones, taking into account refraction effects.

Binding the attributes of a sensory source is necessary to perceive it as a unified entity within its surrounding scene as in the cocktail party problem in auditory perception. It is postulated that coherent temporal modulation of a source's features binds them and enhances their perception. This study seeks evidence for rapid binding among coherently responsive single-neurons in ferret auditory cortex.

Auditory selective spatial attention (ASSA) plays an important role in "cocktail party" scenes, but the effects of spatial separation between target and distractor sources and background noise on the associated brain responses have not been thoroughly investigated. This study utilized the multilayer time-varying brain network to reveal the effect patterns of different separation degrees and signal-to-noise ratio (SNR) levels on brain functional connectivity during ASSA. Specifically, a multilayer time-varying brain network with six time-windows equally divided by each epoch was constructed to investigate the segregation and integration of brain functional connectivity.

Numerous scales have been developed to assess pet-owner relationship quality. One commonly used measure is the Monash Dog Owner Relationship Scale (MDORS) and its various derivatives. Since this scale was published in 2006, many social changes have occurred, necessitating a review and, if necessary, refinement of this measure.

Background: Children receiving general anesthesia while undergoing surgery have a significantly high incidence of emergence delirium (ED). Nonpharmacological interventions yield beneficial effects on preventing pediatric ED. However, the relative effects of nonpharmacological interventions on pediatric ED prevention based on various perioperative phases remain unknown.
