Intrinsic fundamental frequency of Amharic vowels [PDF]
The Journal of the Acoustical Society of America, 2019 Intrinsic fundamental frequency (IF0) refers to the cross-linguistic tendency for high vowels to have a higher F0 than low vowels (Whalen and Levitt, 1995). IF0 is often thought to be a result of mechanical coupling, where tongue movement causes changes in the laryngeal structures, perturbing the F0. Ohala and Eukel (1987) propose that high vowels lead

Calpain small subunit homodimerization is robust and calcium‐independent
FEBS Letters, EarlyView.Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Frequency optimization of laminated composite spherical shells
Science and Engineering of Composite Materials, 2012 This paper deals with frequency optimization of symmetrically laminated angle-ply spherical shells. The design objective is the maximization of the fundamental frequency, and the design variable is the fiber orientation in the layers.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Acoustic cues for the recognition of self-voice and other-voice
Frontiers in Psychology, 2013 Self-recognition, being indispensable for successful social communication, has become a major focus in current social neuroscience. The physical aspects of the self are most typically manifested in the face and voice.

FEBS Letters, EarlyView.Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Diversity and complexity in neural organoids
FEBS Letters, EarlyView.Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Effects of stuttering on fundamental frequency
, 1980 Research Involving the production and perception of speech prior to the moment of stuttering has focused on three general parameters of speech: physiological, perceptual and acoustic.
