The Survey of Neonates in Pomerania: Design, Recruitment and Follow‐Up of the Second Cohort, 2013–2017

open access: yesPaediatric and Perinatal Epidemiology, Volume 39, Issue 2, Page 207-217, February 2025.
ABSTRACT Background The Survey of Neonates in Pomerania (SNiP) is a birth cohort study conducted in Western Pomerania, Germany. SNiP‐I recruited participants at birth between the years 2002 and 2008 (5801 inclusions). Since SNiP‐I, population sociodemographic characteristics and the prevalence of early exposures, including overweight and gestational ...

Determination and evaluation of clinically efficient stopping criteria for the multiple auditory steady-state response technique [PDF]

open access: yes, 2009
Background: Although the auditory steady-state response (ASSR) technique utilizes objective statistical detection algorithms to estimate behavioural hearing thresholds, the audiologist still has to decide when to terminate ASSR recordings introducing ...

Spontaneous emission spectrum of the non-lasing supermodes in semiconductor laser arrays [PDF]

open access: yesOpt. Lett. 23, 391 (1998), 1997
It is shown that the interference between spontaneous emission into the non-lasing supermode and the laser field of a semiconductor laser array causes spatial holeburning which couples the dynamics of the spontaneous emission with the laser field. In particular, phase locking between the spontaneous emission and the lasing mode leads to the formation ...

The characteristic of otoacoustic emissions in full-term neonates according to ABO blood groups

open access: yesBrazilian Journal of Otorhinolaryngology, 2020
Introduction: Previous research has suggested that individuals with different blood groups show varied incidences of noise-induced hearing loss. The reduced otoacoustic emissions amplitudes indicate the higher possibilities of outer hair cell damage for ...

Study on suppression of otoacoustic emissions: lateral domain Estudo da supressão da amplitude das emissões otoacústicas: dominância lateral

open access: yesBrazilian Journal of Otorhinolaryngology, 2011
A pon stimulation by contralateral, ipsilateral or bilateral noise, the medial olivocochlear efferent tract changes the amplitude of otoacoustic emissions relative to the tested ear, reducing or removing it; this resulted in a reduction/suppression ...

Chaotic Dynamics Enhance the Sensitivity of Inner Ear Hair Cells [PDF]

open access: yes, 2019
Hair cells of the auditory and vestibular systems are capable of detecting sounds that induce sub-nanometer vibrations of the hair bundle, below the stochastic noise levels of the surrounding fluid.

A convolutional neural-network model of human cochlear mechanics and filter tuning for real-time applications

open access: yes, 2020
Auditory models are commonly used as feature extractors for automatic speech-recognition systems or as front-ends for robotics, machine-hearing and hearing-aid applications. Although auditory models can capture the biophysical and nonlinear properties of

Damped Bloch oscillations of cold atoms in optical lattices [PDF]

open access: yesPhys. Rev. A 66 (2002) 053405, 2002
The paper studies Bloch oscillations of cold neutral atoms in the optical lattice. The effect of spontaneous emission on the dynamics of the system is analyzed both analytically and numerically. The spontaneous emission is shown to cause (i) the decay of Bloch oscillations with the decrement given by the rate of spontaneous emission and (ii) the ...

Ototoxicity and otoprotection in the inner ear of guinea pigs using gentamicin and amikacin: ultrastructural and functional aspects

open access: yesBrazilian Journal of Otorhinolaryngology, 2008
Summary: Ototoxicity is still a challenge to medicine. The discovery of self-protecting endogenous mechanisms of the outer hair cells associated with their functional and ultra-structural assessment methods has opened new horizons in the understanding ...
