Alcohol Use Predicts Face Perception Impairments and Difficulties in Face Recognition.

: Risky alcohol use is related to a variety of cognitive impairments, including memory and visuo-perceptual difficulties. Remarkably, no prior work has assessed whether usage of alcohol can predict difficulties perceiving facial identity. : Therefore, this study aimed to investigate whether riskier alcohol consumption predicted impairments in face perception and self-reported difficulties in face recognition.

Regressive evolution of an effector following a host jump in the Irish potato famine pathogen lineage.

In order to infect a new host species, the pathogen must evolve to enhance infection and transmission in the novel environment. Although we often think of evolution as a process of accumulation, it is also a process of loss. Here, we document an example of regressive evolution of an effector activity in the Irish potato famine pathogen (Phytophthora infestans) lineage, providing evidence that a key sequence motif in the effector PexRD54 has degenerated following a host jump.

A systematic review examining the impact of blended diets on the gastrointestinal symptoms of people who are enterally fed.

Background: Adults and children who are enterally tube-fed can experience adverse gastrointestinal symptoms (GIS). Observational data suggests that blended diets (BD) could mitigate such symptoms, with potential to improve quality of life and clinical outcomes. We present a novel systematic review examining the impact of BD, compared to commercial feeds, on GIS of adults and children who are tube-fed.

Acoustic imaging of a duct spinning mode by the use of an in-duct circular microphone array.

An imaging method of acoustic spinning modes propagating within a circular duct simply with surface pressure information is introduced in this paper. The proposed method is developed in a theoretical way and is demonstrated by a numerical simulation case. Nowadays, the measurements within a duct have to be conducted using in-duct microphone array, which is unable to provide information of complete acoustic solutions across the test section.

Adaptive beamforming for array signal processing in aeroacoustic measurements.

Phased microphone arrays have become an important tool in the localization of noise sources for aeroacoustic applications. In most practical aerospace cases the conventional beamforming algorithm of the delay-and-sum type has been adopted. Conventional beamforming cannot take advantage of knowledge of the noise field, and thus has poorer resolution in the presence of noise and interference.
