Extreme migratory connectivity and apparent mirroring of non-breeding grounds conditions in a severely declining breeding population of an Afro-Palearctic migratory bird.

Understanding the distribution of breeding populations of migratory animals in the non-breeding period (migratory connectivity) is important for understanding their response to environmental change. High connectivity (low non-breeding population dispersion) may lower resilience to climate change and increase vulnerability to habitat loss within their range. Very high levels of connectivity are reportedly rare, but this conclusion may be limited by methodology.

Long-Range Charge Transport Facilitated by Electron Delocalization in MoS and Carbon Nanotube Heterostructures.

Controlling charge transport at the interfaces of nanostructures is crucial for their successful use in optoelectronic and solar energy applications. Mixed-dimensional heterostructures based on single-walled carbon nanotubes (SWCNTs) and transition metal dichalcogenides (TMDCs) have demonstrated exceptionally long-lived charge-separated states. However, the factors that control the charge transport at these interfaces remain unclear.

Use of Telehealth for Follow-up Care After Children's Mental Health Hospitalizations.

Objectives: This study measured the extent to which the COVID-19 pandemic disrupted follow-up care for children and adolescents with acute mental health hospitalizations and the use of telehealth to offset barriers to in-person follow-up care.

Methods: The study used statewide claims data from Alabama's Children's Health Insurance Program, ALL Kids, from 2017 to 2022. Logit regressions measured associations between receipt of follow-up care within 30 days of acute mental health hospitalization and patient characteristics, timing of the COVID-19 pandemic, and receipt of care via telehealth.

Klinefelter Syndrome: A Review.

Background: Klinefelter syndrome (KS) is an uncommonly recognised condition typified by gynaecomastia, small testes and aspermatogenesis. It is caused by a supernumerary X chromosome, resulting in a 47 XXY karyotype. Since its first description, the phenotype of KS has evolved and there is a much greater appreciation of the subtle features of the condition.
