Abstract We emphasize the distinctive cosmological dynamics in multi-component dark-matter scenarios and their impact on probing a sub-dominant component of dark matter. The originate from conversion among different components. find that temperature self-interacting sub-component matter is significantly enhanced by annihilation into sub-component. same sharply increases required cross section f...

An axiomatic foundation for models of multi-component multiphase porous flow appearing ubiquitously in the engineering literature is developed. This unifies and extends various disparate and empirical formulations appearing in the literature. Constitutive restrictions are derived from an appropriate statement of the second law of thermodynamics, and the corresponding dissipation inequalities es...

Determining accurate velocity measurements from observations of the Sun is vital importance to solar physicists who are studying wave dynamics in atmosphere. Weak chromospheric absorption lines, due dynamic events atmosphere, often consist multiple spectral components. Isolating these components allows for field and quiescent regimes be studied independently. However, isolating such particularl...
