Logistics Distribution Route Optimization Based on Genetic Algorithm.

Aiming at the problem of logistic division based on genetic algorithm, it is planned to study the improvement of logistic distribution methods. We first meet the requirements of the genetic algorithm of logistic development, use the division method to divide the delivery area of the gene, and formulate a functional delivery plan, which generally includes weight measurement, measurement time, customer value measurement, instrument measurement time, and the whole process index. We set weight goals and find the best way to improve genetic algorithm delivery.

Deficits in auditory and visual steady-state responses in adolescents with bipolar disorder.

Background: Many aspects of steady-state responses of the brain remain unclear in bipolar disorder (BD) due to the small number of auditory steady-state response (ASSR) studies and the lack of steady-state visual evoked potential (SSVEP) studies on this complex disorder. Therefore, we assessed the patterns of SSVEP and ASSR in adolescents with BD during an active task to detect possible deficits in these important brain responses compared to normal subjects.

Methods: 27 adolescents with BD and 30 healthy adolescents were assessed in this study.

[Comparative analysis of three hospital systems].

The author compares the hospital system of Hungary with that of New Jersey (USA) and that of the Netherlands. The study discusses, among others, the issue on beds, size, ownership, management, personnel and financing of hospitals. There is a significant deviation in the distributional structure of hospital beds, costs indicators, wage-level and the size of nursing personnel.
