Transportation Journal, Volume 65, Issue 4, Autumn 2026.ABSTRACT The rapid emergence of Maritime Autonomous Surface Ships (MASS) has made the governance of artificial intelligence systems a question of immediate regulatory urgency. The European Union's Artificial Intelligence Act (2024) and the Republic of Korea's AI Framework Act (2025) are the first two horizontal, binding, risk‐tiered AI statutes in ...

Canadian Review of Sociology/Revue canadienne de sociologie, Volume 63, Issue 4, November 2026.ABSTRACT How credibility is constructed under conditions of epistemic uncertainty is a central question in the sociology of knowledge. Telepathic animal communication (TAC) represents a field in which knowledge claims are inherently non‐verifiable, yet services are actively marketed and consumed.

Dust in stellar wind bow shocks [PDF]
, 1989 A number of high velocity O stars have associated parsec-sized structure visible in the IRAS infrared. They can most readily be explained as the dense shells of stellar wind bow shocks.

Systematic search for high-energy gamma-ray emission from bow shocks of runaway stars [PDF]
, 2014 Context. It has been suggested that the bow shocks of runaway stars are sources of high-energy gamma rays (E > 100 MeV). Theoretical models predicting high-energy gamma-ray emission from these sources were followed by the first detection of non-thermal ...

Juno Observations of Langmuir Waves in Association with Interplanetary Shocks from ~1.3 to ~5.4 au
The Astrophysical Journal LettersLangmuir waves are often observed upstream of planetary bow shocks and interplanetary (IP) shocks. Waveform capture (WFC) measurements, obtained during Juno’s cruise phase, reveal the occurrence of Langmuir waves, as well as other wave modes, in ...

Reflection and energization of planetary hydrogen pickup ions at the Martian bow shock
Monthly Notices of the Royal Astronomical SocietyABSTRACT It is generally accepted that a fraction of H$^+$ pickup ions originating from the Martian hydrogen (H) exosphere can be reflected and energized at the bow shock (BS), but the underlying reflection and acceleration mechanisms have not been explicitly identified. Using in situ observations from the Mars Atmosphere and Volatile

Quantifying Non‐Maxwellian Properties of Ion Populations During Reconnection at Earth's Magnetopause
Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.Abstract We investigate ion velocity‐space features within the exhaust of magnetopause reconnection using a global hybrid‐Vlasov simulation. The Hermite transform and Gaussian Mixture Model (GMM) are applied to quantify the complexity of velocity‐space structures that arise during the mixing of magnetospheric and magnetosheath ion populations.

The Anatomical Record, Volume 309, Issue 10, Page 2752-2789, October 2026.Abstract The upper carbonate concretion levels of the Romualdo Formation (Aptian, Brazil) have yielded several theropod dinosaur remains, including spinosaurids and the coelurosaurs Santanaraptor placidus and Mirischia asymmetrica, the phylogenetic affinities of which are controversial.

Thermal emission from bow shocks
Context. X-ray emission from wind-driven bow shocks is both difficult to measure and predict, but may give important insights into the energy budget of the hot phase of the interstellar medium (ISM) by quantifying mixing at the interface between hot and ...

H2 emission from non-stationary magnetized bow shocks
, 2017 International audienceWhen a fast moving star or a protostellar jet hits an interstellar cloud, the surrounding gas gets heated and illuminated: a bow shock is born that delineates the wake of the impact.
