The possible occurrence of bound states $$^3$$ He atoms in the vicinity a weakly attractive substrate coated with thin superfluid $$^4$$ film is investigated by first principle computer simulations. No evidence seen such states, even case weakest substrate, i.e., Cs; single atom always binds to free surface, regardless thickness film. A comparison density profiles computed this work those yield...

The omnipresence of his name and portrait in Bangladesh suggests that Father-of-the-nation Sheikh Mujibur Rahman – known as Bangabandhu is more than just a national hero. He subject secular deification establishes him the fountain political authority an embodiment sovereignty nation one without whom there can be no authority, sovereignty, nation. Historically he was supreme leader movement, ext...

Clusters and nanodroplets hold the promise of enhancing high-order nonlinear optical effects due to their high local density. However, only moderate enhancement has been demonstrated date. Here, we report observation energetic electrons generated by above-threshold ionization (ATI) helium (He) which are resonantly excited ultrashort extreme ultraviolet (XUV) free-electron laser pulses subsequen...

In this paper we present an approach to abductive reasoning in law by examining it in the context of an argumentation scheme for practical reasoning. We present a particular scheme, based on an established scheme for practical reasoning, that can be used to reason abductively about how an agent might have acted to reach a particular scenario, and the motivations for doing so. Plausibility here ...

In this work we present the predictions of a modified version of the “two-infall model” (Chiappini et al. 1997) for the evolution of He, He and D in the Galaxy, as well as their distributions along the Galactic disk. In particular, we show that when allowing for extra-mixing process in low mass stars (M< 2.5 M⊙), as predicted by Charbonnel and do Nascimento (1998), a long standing problem in ch...
