Multilineage potential of adult human mesenchymal stem cells.

Science, 1999
Human mesenchymal stem cells are thought to be multipotent cells, which are present in adult marrow, that can replicate as undifferentiated cells and that have the potential to differentiate to lineages of mesenchymal tissues, including bone, cartilage ...

Comparison of simple potential functions for simulating liquid water

, 1983
Classical Monte Carlo simulations have been carried out for liquid water in the NPT ensemble at 25 °C and 1 atm using six of the simpler intermolecular potential functions for the water dimer: Bernal–Fowler (BF), SPC, ST2, TIPS2, TIP3P, and TIP4P ...

All-atom empirical potential for molecular modeling and dynamics studies of proteins.

Journal of Physical Chemistry B, 1998
New protein parameters are reported for the all-atom empirical energy function in the CHARMM program. The parameter evaluation was based on a self-consistent approach designed to achieve a balance between the internal (bonding) and interaction ...

Membrane potential and Donnan potential

Biophysical Chemistry, 1988
The Nernst-Planck-Poisson equations for the potential profile across a membrane are exactly solved without recourse to the assumption of constant field within the membrane. It is assumed that the membrane core of thickness dc is covered by a surface layer of thickness ds in which the membrane-fixed charges are distributed at a uniform density N.

Hybrid functionals based on a screened Coulomb potential

, 2003
Hybrid density functionals are very successful in describing a wide range of molecular properties accurately. In large molecules and solids, however, calculating the exact (Hartree–Fock) exchange is computationally expensive, especially for systems with ...

Potential Games

, 1994
We define and discuss several notions of potential functions for games in strategic form. We characterize games that have a potential function, and we present a variety of applications .

The Potential of Potentiality Arguments

2017
We contend that both the defenders and critics of potentiality arguments in the abortion debate have failed to appreciate the morally relevant aspects of potential. Crucial for understanding the moral significance of potentiality is the fact that mindless organisms have interests but only in their healthy development.

The preference for potential.

Journal of Personality and Social Psychology, 2012
When people seek to impress others, they often do so by highlighting individual achievements. Despite the intuitive appeal of this strategy, we demonstrate that people often prefer potential rather than achievement when evaluating others. Indeed, compared with references to achievement (e.g., "this person has won an award for his work"), references to ...

Coping with stress during childhood and adolescence: problems, progress, and potential in theory and research.

Psychological bulletin, 2001
Progress and issues in the study of coping with stress during childhood and adolescence are reviewed. Definitions of coping are considered, and the relationship between coping and other aspects of responses to stress (e.g., temperament and stress ...
