Migratory movements of bats are shaped by barrier effects, sex-biased timing and the adaptive use of winds.

Background: Migratory bats perform seasonal movements between their summer and winter areas. When crossing ecological barriers, like the open sea, they are exposed to an increased mortality risk due to energetically demanding long-distance flights and unexpected inclement weather events. How such barriers affect bat migratory movements is still poorly known.

Adapting an early autism caregiver coaching intervention for telehealth delivery in low-resource settings: A South African study of the 'what' and the 'why'.

We were busy with an early autism caregiver-coaching programme in South Africa, when COVID-19 stopped all in-person work. We changed the programme so it could be done using computers and/or phones. Here, we describe programme changes (which we call the 'what') and the reasons for those changes (which we call the 'why').

Binary Nature of Collisions Facilitates Runaway Electron Generation in Weakly Ionized Plasmas.

Dreicer generation is one of the main mechanisms of runaway electron generation in weakly ionized plasmas. It is often described as a diffusive flow from the Maxwellian core into high energies under the effect of the electric field. In this Letter we demonstrate a critical role of the binary nature of inelastic collisions in weakly ionized plasma during tokamak startup, where some electrons experience virtually no collisions during acceleration to the critical energy.

[Trial of labor and gynecological uterine scars : a narrative review].

The increasing number of women of childbearing age with gynecological uterine scars presents a significant clinical challenge. -Planning the route of birth for a subsequent pregnancy necessitates -careful consideration and should be the subject of an informed -discussion. Unfortunately, the heterogeneity of data in the literature with regards to gynecological uterine scars makes this choice -debatable.
