Microbial transition state theory (MTS) offers a theoretically explicit mathematical model for substrate limited microbial growth. By considering a first order approximation of the MTS equation one recovers the well-known Monod’s expression for growth, which was regarded as a purely empirical function...
Density functional theory The DFT calculations were performed using the projector augmented wave method50,51and the Perdew-Burke-Ernzerhof (PBE)52exchange-correlation functional within the VASP53,54,55,56code. The kinetic energy cutoff was set to 400 eV and a 5 × 15 × 4 k-point...
model coupling theory是一个微观理论（也有人认为不是），可惜只能在Tx以上才适用，通常的理解是，model...
A Model of Successful Transition from Home to a Long-Term Care Community: A Grounded Theory Study The transition process and experience for older adults who move to independent and assisted-living communities is unique to each person but a universal iss... DJ Koltz - 《Gerontology & Geriatric ...
The theory is based on the continuum theory of mixtures formulated to include the compressibility of all phases and the compaction behavior of the granular material. By requiring the model to satisfy an entropy inequality, specific expressions for the exchange of mass, momentum and energy are ...
Theory and Bonding of Inorganic Nonmolecular Systems 3.03.2.4 Miscellaneous systems Transition metals also exist in a 1:1 stoichiometric phase with boron (Fig. 6A). But the boron chains here show bending with bond angles 110 degrees indicative of sp3 hybridized BB single bonds and have identical...
Therefore, without understanding this critical transition problems, it seems to be unlikely to proceed toward a comprehensive theory of cosmology. Based on these motivations, in this study, we will focus on the late time transition of Universe and propose a new model to solve these challenging ...
We have derived the nonlinear Dirac Hamiltonian (equation (25)) as the effective theory of the low-energy dispersion of the nonlinear QWZ model around the critical amplitude. For example, if we focus on the critical amplitude wc = (−2 − u)/κ, the nonlinear band structure of...
