Advanced algorithms for monochromatic monitoring of complex optical coatings.

The paper proposes to use combinations of two algorithms for the on-line prediction of the termination times of layer depositions in the case of complex optical coatings with large numbers of layers with significantly different layer thicknesses. Notch filters with very thin and thick coating layers are considered as examples of coatings where such combinations of algorithms can be useful. Computational manufacturing experiments are used to estimate expected levels of thickness errors and the strength of the error self-compensation effect for various notch filter designs.

Pre-production estimates for the choice of strategy and algorithm for monochromatic monitoring of the production of optical coatings.

The paper proposes an approach for the pre-production selection of the most promising combination of a monochromatic monitoring strategy and a monitoring algorithm used for predicting termination of layer deposition. The approach is based on the previously introduced estimate of the strength of the expected error self-compensation effect and the new estimate, to the best of our knowledge, of the strength of the cumulative effect of thickness error growth presented in this paper. The application of the proposed approach is demonstrated using computational manufacturing experiments with various types of optical coating designs.

Turning point monitoring of narrow bandpass filters: the enormous strength of the error self-compensation effect.

It is generally accepted that turning point optical monitoring provides a very strong error self-compensation effect when used to control the deposition of narrow bandpass filters with quarter-wave or multiple-quarter-wave layer optical thicknesses. However, how strong this effect is has never been assessed before, to our knowledge. A recently developed general approach to estimating the strength of thickness error correlation and the strength of the associated error self-compensation effect allows, possibly for the first time, such an assessment.

[Season fluctuations of carbamazepine and valproate concentration in patients with epilepsy].

We studied 107 patients with epilepsy who received monotherapy with valproic acid drugs (58) and carbamazepine (49). The seasonal distribution of number and severity of seizures assessed with the NHS3 scale in dependence of Cmin and Cmax content of antiepileptic drugs carbamazepine and valproates in the serum of patients was estimated. There was a significant increase in the number of seizures and their severity in the cycle spring>autumn>summer>winter.

Effects of tenoten on anxiety and depression disorders in patients with epilepsy.

The efficiency and safety of tenoten for anxiety and depression disorders in epileptics has been demonstrated. The drug does not change the incidence and severity of epileptic episodes, does not deteriorate the course of the underlying disease, and can be well combined with anticonvulsants. The results indicate the efficiency of tenoten used to arrest the anxio-depressive disorders in epilepsy.

[Concentrations of urine 6-sulfatoxymelatonin during the treatment of patients with epilepsy: a pilot clinical trial].

The effect of the epiphysis hormone melatonin on the brain bioelectrical activity is understudied: the data of experimental and clinical studies of melatonin effects are inconclusive and related mostly to exogenous administration. We studied 43 patients with focal epilepsy, 25 patients with cryptogenic epilepsy and 18 with symptomatic epilepsy. Carbamazepine and valproate were used as anticonvulsive drugs.

[Autochronometry in patients with focal epilepsy].

A study included 163 patients with focal cryptogenic and symptomatic forms of epilepsy and 47 sex- and age-matched controls. Disturbances of autochronometry in epileptic patients were studied with regard to character, duration, severity, seasonality of seizures and localization of pathological activity in EEG. The elongation of internal count of chronominutes and the ratio of individual chronominute to duration of daylight hours suggest either the approach of a seizure or the early post seizure period, the effect of the completed seizure.
