[Clinical protocol: audiological assessment of infants in Russian Federation. Part II].

This is the second part of the previously published clinical protocol of audiological assessment in infants. The goal of the protocol is unification approaches to audiological diagnosis of the infants. The following sections were included in the second part of the protocol: behavioral testing in infants, testing sequence, duration of the examination and necessity in follow-up, hearing assessment in special cases (premature children, children with congenital infections, after meningitis, with external ear abnormalities, single-sided deafness, with hydrocephalus and shunts, with auditory neuropathy spectrum disorder, with mild hearing loss and otitis media with effusion), medical report.

Second-Order Temporal Coherence of Polariton Lasers Based on an Atomically Thin Crystal in a Microcavity.

Bosonic condensation and lasing of exciton polaritons in microcavities is a fascinating solid-state phenomenon. It provides a versatile platform to study out-of-equilibrium many-body physics and has recently appeared at the forefront of quantum technologies. Here, we study the photon statistics via the second-order temporal correlation function of polariton lasing emerging from an optical microcavity with an embedded atomically thin MoSe_{2} crystal.

Impact of Prematurity on Auditory Processing in Children.

Prematurity is one of the most crucial risk factors negatively affecting the maturation of the auditory system. Children born preterm demonstrate high rates of hearing impairments. Auditory processing difficulties in preterm children might be a result of disturbances in the central auditory system development and/or sensory deprivation due to peripheral hearing loss.

[Clinical protocol: audiological assessment of infants in Russian Federation. Part I].

The clinical protocol of audiological assessment in infants was prepared by the workgroup of Russian pediatric audiologists from different regions. The goal of the protocol is unification approaches to audiological diagnosis of the infants. The protocol has been developed according the evidence based medicine principles, by reviewing current scientific publications on the topic and taking into account the order of providing medical services and other clinical practice guidelines.

Bogolon-mediated light absorption in atomic condensates of different dimensionality.

In the case of structureless bosons, cooled down to low temperatures, the absorption of electromagnetic waves by their Bose-Einstein condensate is usually forbidden due to the momentum and energy conservation laws: the phase velocity of the collective modes of the condensate called bogolons is sufficiently lower than the speed of light. Thus, only the light scattering processes persist. However, the situation might be different in the case of composite bosons or the bosons with an internal structure.
