Frontiers in Astronomy and Space SciencesGalaxies with narrow emission lines play a crucial role in testing the theoretical values of transition probabilities, especially for lines that need conditions that are hard to produce in laboratory plasma, and hence the theoretical values could not be ...

The 40K‐K dating system: 1. Improving data interpretation using new model calculations
Meteoritics &Planetary Science, EarlyView.Abstract The 40K‐K cosmic‐ray exposure (CRE) dating system offers a promising method for determining exposure ages of iron meteorites by combining the radioactive cosmogenic 40K with the stable cosmogenic isotopes 39K and 41K. However, earlier applications relied on semi‐empirical production models and inconsistent analytical data sets, limiting their ...

Nature's Complexity Alive: Farewell to Several Unificatory Cosmological Arguments for Monism
Noûs, EarlyView.ABSTRACT Throughout history, numerous thinkers have claimed that monism—in the form of priority monism, existence monism, monotheistic monism, or versions that posit an extra‐cosmic ultimate being—theoretically surpasses pluralism, above all by positing a unified universe.

New Phytologist, EarlyView.A model of the C‐repeat binding factor–salicylic acid (CBF–SA) module in plant wound healing. Summary Repairing damaged tissues is essential for the survival of all organisms. In plants, tissue injury rapidly triggers defense and repair programs. However, the molecular mechanisms linking early injury cues to the later stage of wound repair remain ...
