Postfiltering with Complex Spectral Correlations for Speech and Audio Coding

open access: yes, 2018
State-of-the-art speech codecs achieve a good compromise between quality, bitrate and complexity. However, retaining performance outside the target bitrate range remains challenging.

Voice-Based Detection of Parkinson’s Disease Using Machine and Deep Learning Approaches: A Systematic Review

open access: yesBioengineering
Parkinson’s disease (PD) is a progressive neurodegenerative disorder characterized by motor and non-motor symptoms, among which vocal impairment is one of the earliest and most prevalent. In recent years, voice analysis supported by machine learning (ML)

De novo synthesis of short‐chain aldehydes and hydrocarbons secreted by the brown marmorated stink bug Halyomorpha halys

open access: yesFEBS Open Bio, EarlyView.
The brown marmorated stink bug, Halyomorpha halys, mainly secretes 4‐oxo‐(E)‐2‐hexenal, (E)‐2‐decenal, dodecane and tridecane, a mixture representative of that released by many heteropterans. We demonstrated that H. halys can synthesise these secretory components de novo using dietary glucose.

Dual native G‐quadruplex folding is associated with chromatin looping at the MYC locus

open access: yesFEBS Open Bio, EarlyView.
BG4‐detectable G‐quadruplex (G4) in HaCaT and NHEK keratinocytes identified folded and unfolded G4s enriched at promoters/TSSs and active enhancers, whereas unfolded G4s also overlapped weak/poised enhancers. At MYC–PVT1, 3C‐qPCR detected enhancer–promoter looping only when G4s were simultaneously folded at both regulatory elements under native ...

Character-level linguistic biomarkers for precision assessment of cognitive decline: a symbolic recurrence approach

open access: yesFrontiers in Aging Neuroscience
Early-stage Alzheimer's disease (AD) remains difficult to assess using conventional linguistic or cognitive assessments, which often overlook subtle and individualized disruptions in speech.

Heterotropic regulation and negative homotropic cooperativity

open access: yesFEBS Open Bio, EarlyView.
We identified a structural module common to some proteins that couple negative cooperativity with heterotropic regulation, two features that rarely coexist. These proteins are ring‐like and present an ordered asymmetry whereby noncontacting subunits are symmetric, and their tertiary structure differs from that of contacting subunits.

A Quantitative Comparison of Epoch Extraction Algorithms for Telephone Speech

open access: yes, 2019
Telephone speech is one of the degradations involved in building speech systems in practical environments. The potential use of the speech systems depends on the speech analysis algorithms that can handle different acoustic variations and degradations ...

From patient advocacy to patient‐driven research: Building active partnerships beginning at the bench to reach the bedside

open access: yesFEBS Open Bio, EarlyView.
Research is strongest when conducted alongside patients, not just about them. Patient research organizations help integrate patient perspectives into research priorities, study design, and scientific meetings, leading to meaningful patient outcomes and development of relevant therapies.

The effect of modality and speaking style on the discrimination of non-native phonological and phonetic contrasts in noise

open access: yes, 2015
Auditory speech is difficult to discern in degraded listening conditions, however the addition of visual speech can improve perception. The Perceptual Assimilation Model [1] suggests that non-native contrasts involving a native phonological difference ...
