A circumpolar review of the breeding distribution and habitat use of the snow petrel (), the world's most southerly breeding vertebrate.

Knowledge of the spatial distribution of many polar seabird species is incomplete due to the remoteness of their breeding locations. Here, we compiled a new database of published and unpublished records of all known snow petrel breeding sites. We quantified local environmental conditions at sites by appending indices of climate and substrate, and regional-scale conditions by appending 30 year mean (1992-2021) sea-ice conditions within accessible foraging areas.

pBn type short-wavelength infrared photodetector with an ultralow dark current and extended wavelength based on a strained InGaAs/GaAsSb superlattice.

An InGaAs/GaAsSb type II superlattice (T2SL) absorber is a promising alternative material for a short-wavelength infrared (SWIR) photodetector due to the largely tunable bandgap by adjusting the thickness and material composition of InGaAs and GaAsSb in each T2SL period. We demonstrate a pBn type SWIR photodetector consisting of a strained InGaAs/GaAsSb T2SL absorber and AlGaAsSb barrier. The device presents an ultralow dark current density of 1.

Factors associated with early-career GPs' retention as independent specialists in former training practices.

Introduction: Retention of general practice registrars in their training practices is important for addressing the GP workforce deficit and maldistribution of GPs. Given that rural and remote general practices are disproportionately affected by low retention, identifying the factors that promote retention may be as important as developing recruitment strategies in these areas. Quantifying the impact of relevant factors on registrar retention will enable a better understanding of how to incentivise retention and attenuate the loss of the rural workforce to other areas.
