Interactions of Interaural Time and Level Differences in Spatial Hearing with Cochlear Implants

Advanced Science, EarlyView.
Differences in timing (ΔT) are weighted heavily compared to differences in loudness (ΔL) in binaural hearing with cochlear implants. Abstract Normally hearing humans can localize sound sources quite accurately, with minimum audible angles as small as 1°. To achieve this, these auditory pathways combine information from multiple acoustic cues, including

Iron Overload Mediates the Differential Cell Fate of Astrocytes from Neurons and Its Regulatory Mechanisms in Ischemic Stroke

Advanced Science, EarlyView.
Upon ischemia/reperfusion‐induced iron overload condition, neurons and astrocytes exhibit similar oxidative stress changes but opposite alterations in endogenous antioxidant defense mechanisms, leading to divergent ferroptotic outcomes. The iron deposition and neuronal loss are increased within the perilesional cortex of stroke patients ...

Balanced Expression of the Diiron Oxygenase BioE Is Essential for Biotin Homeostasis in Elizabethkingia meningoseptica

Advanced Science, EarlyView.
BioE is a new diiron oxygenase that catalyzes the conversion of long‐chain acyl groups into pimeloyl thioester, initiating biotin synthesis. The overexpression of EmBioE disrupts lipid metabolic homeostasis, requiring repressor BioL to maintain a balance between long‐chain fatty acids and biotin synthesis.

Failure analysis of a Ti6Al4V cementless HIP prosthesis

Engineering Failure Analysis, 2007
This work investigates the causes of in vivo fracture of a cementless hip prosthesis model manufactured with Ti6A14V alloy. To this end an assessment of geometric characteristics, a fractographic analysis of the fracture surface, and a microstructural study of the stem material were carried out.
