Article Synopsis
- The study aimed to explore how cochlear implant (CI) patients describe sound quality compared to descriptions given by single-sided deaf (SSD) patients for their normal-hearing ears.
- Participants included patients with different CI brands who completed a questionnaire focused on sound quality using 25 descriptive adjectives, assessing their impressions near activation and years later.
- Results showed that initial descriptors included terms like "Computer-like" and "Metallic," but evolved to "Clear" over time, indicating that experienced CI users may notice less about sound discrepancies compared to SSD patients who have a normal hearing benchmark.
Cochlear implant (CI) systems differ in terms of electrode design and signal processing. It is likely that patients fit with different implant systems will experience different percepts when presented speech via their implant. The sound quality of speech can be evaluated by asking single-sided-deaf (SSD) listeners fit with a cochlear implant (CI) to modify clean signals presented to their typically hearing ear to match the sound quality of signals presented to their CI ear.

Here, we developed a multi-stage multi-resolution ensemble model that predicts daily NO concentration across continental France from 2005 to 2022. Innovations of this work include the computation of daily predictions at a 200 m resolution in large urban areas and the use of a spatio-temporal blocking procedure to avoid data leakage and ensure fair performance estimation.

We assessed the degree to which synchronizing left and right AGCs mitigates those difficulties as indicated by listeners' ability to use the changes in interaural level differences that come with head movements to avoid front-back reversals (FBRs).
Design: Broadband noise stimuli were presented from one of six equally spaced loudspeakers surrounding the listener.
Article Synopsis
- Yemen has been facing the largest cholera outbreak in modern history since 2016, with a significant rise in multidrug-resistant (MDR) cholera strains observed since 2018.
- Analysis of 260 V. cholerae isolates from 2018 to 2019 revealed that a majority (84%) were part of the O1 serogroup and belonged to the seventh pandemic El Tor lineage, while the remaining 16% were non-toxigenic strains from different lineages.
- The emergence of MDR plasmids in cholera strains indicates a potential genetic exchange between epidemic and endemic strains, underscoring the need for ongoing genomic surveillance to manage and control cholera effectively.
