Discussion of issues pertinent to free energy perturbation: D.A.

An alternative to free energy perturbation for computing potentials of mean force in chemical space is thermodynamic integration.

A potentially more reliable but much more computationally demanding alternative to scoring functions are free energy perturbation calculations.

Alternatives to umbrella sampling for computing potentials of mean force or reaction rates are free energy perturbation and transition interface sampling.

This method, also called Free energy perturbation (or FEP), involves sampling from state A only.

During Free Energy Perturbation, one chemical species is slowly transformed into another and the energy change associated with the transformation is measured.

In order to perform a Free Energy Perturbation, the properties of the perturbed ATOMs must also be set.

Perturbed charge This property is the monopole charge on an ATOM at the completion of a Free Energy Perturbation calculation.

During Free Energy Perturbation, the potential energy function of one molecular species is slowly perturbed to that of a second molecular species through a perturbation parameter called $lambda$.

More advanced features include free energy perturbation (FEP), quasi-harmonic entropy estimation, correlation analysis and combined quantum, and molecular mechanics (QM/MM) methods.

Free energy perturbation calculations only converge properly when the difference between the two states is small enough; therefore it is usually necessary to divide a perturbation into a series of smaller "windows", which are computed independently.

Free energy perturbation (FEP) is a method based on statistical mechanics that is used in computational chemistry for computing free energy differences from molecular dynamics or Metropolis Monte Carlo simulations.

One of his early works from 1954 is often cited as the first use of free energy perturbation theory, and the resulting equation for the change in free energy is sometimes referred to as the "Zwanzig equation".

Booksellers sometimes refer to the front end paper as FEP.

Several software packages have been developed to help perform FEP calculations.

The FEP picked up the parade and keeps it going along with other exemplary programs.

The scientists from the FEP are confident that, in the long term, the treatment with electrons will prove to be a success story.

To support the Quest, FEP also sold a line of upgrade accessories.

The usage of an FEP is much easier when it is integrated into the editor.

One FEP member was elected to one of the 166 seats reserved for individual candidates.

In 2008, both FEP plan options will incur only single-digit premium increases.

Should the treatment with electrons gain greater acceptance, the scientists from FEP could license their process to plant construction companies.

Said was the first President of FEP.

As described in the introduction, when FEP or slow growth is performed, double-wide sampling can be carried out.

An assumed annual average improvement of 0.35 percent in marine efficiency, which includes 0.05 percent from FEP.

The entirety of the FEP product line was virtually discontinued in 2007 when the company disbanded.

The Quest paintball marker is FEP's main product and has been the basis for the company.

The FEP defends the rights of professional photographers directly and in communion with national and international organisations.

Ever since its inception, FEP has grown in terms of students' intake, number of academic programs offered, research activities, and professional services.

There were endless and tiring discussions to decide if FEP should exist as a self-governing organization.

In this way the application can tolerate very large amounts of traffic or the failure of FEP hardware.

Fluorinated ethylene propylene (FEP) is the second most produced fluoropolymer.

Adding the FEP members increases the value of the tool to physicians in providing care for their members as well."

She added: "I'm very proud that our plan was recognized and rewarded for its outstanding service on behalf of FEP."

On the inside of the cover page, extending to the facing page is the front endpaper sometimes referred as FEP.

The FEP was finally registered under Belgian Law on January 1999.

This many-to-one access offers considerable savings on the FEP by reducing the number of ports required to support users.
