And Behavior

Petri nets have structure and behavior properties, it is convenient to analyze some complex system based on its mathematical analysis methods. Online top-up system is an open network system. The modeling method of this system based on general Petri net has some limitations. A new modeling method based on open Petri net to study online top-up system is proposed, and analyze the open Petri net model by T-invariant. This method laid a foundation for the study of open online top-up system.

The article presents the results of the research concerning the pharmacotherapy of patients with chronic pancreatitis with comorbidity from the pharmacological view. During the study pharmacological approach to the problem of comorbidity among patients with chronic pancreatitis was analyzed. A survey among doctors and pharmacists was used during the research along with normative and legal, documentary, retrospective, bibliographic, systemic, forensic-pharmaceutical, sociological (questionnaire survey), comparative, graphic, mathematical analysis methods. The most common comorbid diseases that patients suffer from alongside with chronic pancreatitis were highlighted. Authors came to conclusion, that development of safe and affordable pharmaceutical therapy for patients with chronic pancreatitis and comorbidity is very important.

Abstract. A study of the regularity of precipitation distribution at the airdromes of Azerbaijan Republic was carried out for the purpose of defining the basic parameters of the climatic peculiarity that have an impact on the activities of civil aviation. For calculation of the key parameters, mathematical analysis methods are applied on the long-term statistical data.

Detailed Mathematical Analysis

Density waves in the nature of those proposed by B. Lindblad are described by detailed mathematical analysis of collective modes in a disk-like stellar system. The treatment is centered around a hypothesis of quasi-stationary spiral structure. We examine (a) the mechanism for the maintenance of this spiral pattern, and (b) its consequences on the observable features of the galaxy.

Better Than

In order to better understand the distribution of cell traction forces generated by rapidly locomoting cells, we have applied a mathematical analysis to our modified silicone rubber traction assay, based on the plane stress Green’s function of linear elasticity. To achieve this, we made crosslinked silicone rubber films into which we incorporated many more latex beads than previously possible (Figs. 1 and 6), using a modified airbrush. These films could be deformed by fish keratocytes, were virtually drift-free, and showed better than a 90% elastic recovery to micromanipulation (data not shown). Video images of cells locomoting on these films were recorded. From a pair of images representing the undisturbed and stressed states of the film, we recorded the cell’s outline and the associated displacements of bead centroids using Image-1 (Fig. 1). Next, using our own software, a mesh of quadrilaterals was plotted (Fig. 2) to represent the cell outline and to superimpose on the outline a traction density distribution. The net displacement of each bead in the film was calculated from centroid data and displayed with the mesh outline (Fig. 3).
