The ground state of pluripotency

Biochemical Society Transactions, 2010
Pluripotency is defined as the capacity of individual cells to initiate all lineages of the mature organism in response to signals from the embryo or cell culture environment. A pluripotent cell has no predetermined programme; it is a blank slate. This is the foundation of mammalian development and of ES (embryonic stem) cell biology.

Asymptotics of atomic ground states: The relation between the ground state of helium and the ground state of He+

Journal of Mathematical Physics, 1981
The asymptotic behavior of ground states of two-electron atoms is investigated. Suppose ψ(x1,x2) is the ground state of helium, ρ(x1) = ℱψ2(x1,x2) dx2 the corresponding electron density, and Φ(x2) the ground state of He+. We show that in the L2(dx2)-sense, lim‖x1‖→∞ ψ(x1,x2)[ρ(x1)]−1/2 = Φ(x2), and that ψ[ρ(x1)]−1/2 solves for large ‖x1‖ the ...

The ground state of NaV2O5

Solid State Communications, 1998
Abstract Neutron and X-ray diffraction experiments have shown that NaV 2 O 5 consists of zig-zag V chains of average valence 4.5 rather than a charge ordered state at room temperature. Both these experiments revealed superlattice reflections below the phase transition temperature T SP ≈34 K.

Energy of the ground state of Be

Theoretical and Experimental Chemistry, 1970
The contributions from the diagrams of the first two orders are calculated for the energy of the ground state of Be. The result is E2= =−1.25 Z2+1.55927422 Z−0.8775, with E 2 corr =−0.01172683 Z −0.0720. Perturbation theories for the ground-state energy of Be are compared for Hartree-Fock and hydrogen-

The ground state of harmonium

The Journal of Chemical Physics, 2000
A detailed analysis that benefits from a slate of new approximate numerical and exact asymptotic results produces highly accurate properties of the ground state of the harmonium atom as functions of the confinement strength ω and quantifies the domains of the weakly and strongly correlated regimes in this system.

The ground state of H2CO

Journal of Molecular Spectroscopy, 1978
Abstract The analysis of high resolution spectra of H 2 CO in the 3.5 μ region reveals that the observed combination differences with Δ K a = 2 for K a > 5 do not agree with the energy level differences calculated from the microwave-determined ground state constants.
