Measuring entropy values of QRS-complexes before and after training program of sport horses with ECG
Zarife Zararsiz 원광대학교 기초자연과학연구소 2018 ANNALS OF FUZZY MATHEMATICS AND INFORMATICS Vol.15 No.3
In the present paper, $QRS$- complexes in ECG for sport horses are transformed to fuzzy sets. By means of this transformation, we calculate entropy and similarity measure values by using the amplitude and the duration of $QRS$-complexes of sport horses. In addition, the results before and after 5 months training program are calculated and some significant comments are given. Besides, Riesz entropy notion is introduced. Finally, Riesz entropy values of $QRS$-complexes are calculated for sport horses before and after 5 months training program.

Background: The aim of the present study was to determine the predictive/prognostic value of the secreted protein, acidic and rich in cysteine (SPARC) in cases of unresectable, locally advanced, non-small cell lung cancer. Materials and Methods: The study included 84 patients with Stage IIIA-B non-small cell lung cancer, undergoing simultaneous chemoradiotherapy including radiotherapy at a dose of 66 Gy and weekly docataxel ($20mg/m^2$) and cisplatin ($20mg/m^2$). SPARC expression was studied in biopsy material by immunohistochemical methods and correlations with treatment responses or survival were evaluated. Results: Median overall survival was $16{\pm}2.73$ (11.55-20.46) months for low expression vs $7{\pm}1.79$ months (7.92-16.08) months for high expression (p=0.039), while median local control was $13{\pm}2.31$ (8.48-17.5) months for low expression vs $6{\pm}0.85$ (4.34-7.66) months for high expression (p=0.045) and median progression-free survival was $10{\pm}2.31$ (5.48-14.5) months for low expression vs $6{\pm}1.10$ (3.85-8.15) months for high expression (p=0.022). In both univariate and multivariate analyses, high SPARC expression was associated with significantly shorter overall survival (p=0.003, p=0.007, respectively), local control (p=0.008, p=0.036) and progression-free survival (p=0.004, p=0.029) when compared to low SPARC expression. No significant difference was detected between high and low SPARC expression groups regarding age, sex, T stage, N stage, histopathology and stage-related patient characteristics. Conclusions: High SPARC expression was identified as a poor prognostic factor in cases with locally advanced NSCLC treated with concurrent chemoradiotherapy.
