Of a comprehensive framework that transcends the partial scope of disciplinary worldviews through an overarching synthesis, such as general systems, feminist theory, and sustainability. The term also connotes a new structure of unity informed by the worldview of complexity in science and a new mode of knowledge production that draws on expertise from a wider range of organizations, and collaborations with stakeholders in society.

transient lunar phenomenon (TLP)
padide-ye mângi-ye gozarâ, ~ mâhi-ye
Fr.: phénomène lunaire transitoire
A short-lived change in the brightness of patches on the face of the Moon. The TLPs last from a few seconds to a few hours and can grow from less than a few to a hundred kilometers in size. They have been reported by many observers since the invention of the telescope. However, the physical mechanism responsible for creating a TLP is not well understood. Several theories have been proposed, among which lunar outgassing, that is, gas being released from the surface of the Moon.
Fr.: ciel transitoire
A general term for all events of astronomical nature occurring in the sky and lasting only for a relatively short duration, such as → supernova explosions, → gamma-ray bursts, → flare stars, → luminous red novae, eclipsing brown dwarfs, → tidal disruption events, etc.
transient X-ray source

An active semiconductor device with a small low-powered solid-state electronic device consisting of a semiconductor and three or more electrodes, used as an amplifier and rectifier and frequently incorporated into integrated circuit chips. Although much smaller in size than a vacuum tube, it performs similar functions without requiring current to heat a cathode.
1) An event where one astronomical object appears to move across the
face of another. As seen from Earth, the planets Venus and Mercury are
seen to transit the Sun. We can also observe natural satellites transit the
face of their host planet. Similarly exoplanets have been observed to transit their
host stars. See also → planetary transit,
→ transit method.
