Force Field (chemistry)
In the context of chemistry and molecular modelling, a force field is a computational method that is used to estimate the forces between atoms within molecules and also between molecules. More precisely, the force field refers to the functional form and parameter sets used to calculate the potential energy of a system of atoms or coarse-grained particles in molecular mechanics, molecular dynamics, or Monte Carlo simulations. The parameters for a chosen energy function may be derived from experiments in physics and chemistry, calculations in quantum mechanics, or both. Force fields are interatomic potentials and utilize the same concept as force fields in classical physics, with the difference that the force field parameters in chemistry describe the energy landscape, from which the acting forces on every particle are derived as a gradient of the potential energy with respect to the particle coordinates. ''All-atom'' force fields provide parameters for every type of atom in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

UCSF
The University of California, San Francisco (UCSF) is a public land-grant research university in San Francisco, California. It is part of the University of California system and is dedicated entirely to health science and life science. It conducts research and teaching in medical and biological sciences. UCSF was founded as Toland Medical College in 1864. in 1873, it became affiliated with the University of California as its Medical Department. In the same year, it incorporated the California College of Pharmacy and in 1881 it established a dentistry school. Its facilities were located in both Berkeley and San Francisco. In 1964, the school gained full administrative independence as a campus of the UC system, headed by its own chancellor, and in 1970 it gained its current name. Historically based at Parnassus Heights with satellite facilities throughout the city, UCSF developed a second major campus in the newly redeveloped Mission Bay district in the early 2000s.

Molecular Dynamics
Molecular dynamics (MD) is a computer simulation method for analyzing the physical movements of atoms and molecules. The atoms and molecules are allowed to interact for a fixed period of time, giving a view of the dynamic "evolution" of the system. In the most common version, the trajectories of atoms and molecules are determined by numerically solving Newton's equations of motion for a system of interacting particles, where forces between the particles and their potential energies are often calculated using interatomic potentials or molecular mechanical force fields. The method is applied mostly in chemical physics, materials science, and biophysics. Because molecular systems typically consist of a vast number of particles, it is impossible to determine the properties of such complex systems analytically; MD simulation circumvents this problem by using numerical methods. However, long MD simulations are mathematically ill-conditioned, generating cumulative errors in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
