State initial, optimal

This problem may also be solved by numerical integration using the E-Z Solve software (file exl4-3.msp). This simulation is well-suited to the investigation of the effect of initial conditions on the time for a specified approach to steady-state. To optimize... [Pg.342]

Fig. 2.15 Geometry optimization to a minimum gives the minimum closest to the input structure. The input structure A is moved toward the minimum A, and B toward B. To locate a transition state a special algorithm is usually used this moves the initial structure A toward the transition state TS. Optimization to each of the stationary points would probably actually require several...

The time for antidepressant onset of effect in BN is unclear. In the absence of data, the definition of a therapeutic trial from the depression hterature (4 to 8 weeks at a therapeutic dose) should be used. Since the majority of subjects will not experience a complete remission, and there are few data on predictors of response or whether switching to another class will improve response, a clear and specific target should be stated initially. Eor example, will the medication be continued if the patient has a 50% reduction in binge-purge episodes, or if abstinence from such behavior is the ultimate therapeutic goal. Optimal duration of treatment after response is also poorly defined. Most clinicians will treat for 6 months to 1 year and then re-evaluate the need for ongoing treatment. The evidence is mixed as to whether any early benefit is sustained, hence the decision to continue treatment should be made based on both initial response and the maintenance of that benefit. If the symptoms return within a few months after the antidepressant is discontinued, then the treatment may need to be reinitiated. [Pg.1153]

The initial geometry of the transition states was optimized in the GAMESS program with approximation of MP2(fc)/6-31G(d) by setting RUNTYP = SADPOINT under SCONTRL. [Pg.119]
