Alternate Approach of Comparison for Selection Problem

Authors: Nikhil Shaw
Comments: 8 Pages.

In computer science, a selection algorithm is an algorithm for finding the kth smallest number in a list or array; such a number is called the kth order statistic. This includes the cases of finding the minimum, maximum, and median elements. There are O(n) (worst-case linear time) selection algorithms, and sublinear performance is possible for structured data; in the extreme, O(1) for an array of sorted data. Selection is a subproblem of more complex problems like the nearest neighbour and shortest path problems. Many selection algorithms are derived by generalizing a sorting algorithm, and conversely some sorting algorithms can be derived as repeated application of selection. This new algorithm although has worst case of O(n^2), the average case is of near linear time for an unsorted list.

Epstein Bar Virus (Ebv) a Cause of Human Breast Cancer.

Authors: Ilija Barukčić
Comments: 29 Pages. Copyright © 2017 by Ilija Barukčić, Jever, Germany. Published by:

Epstein-Barr Virus (EBV) has been widely proposed as a possible candidate virus for the viral etiology of human breast cancer, still the most common malignancy affecting females worldwide. Due to possible problems with PCR analyses (contamination), the lack of uniformity in the study design and insufficient mathematical/statistical methods used by the different authors, findings of several EBV (polymerase chain reaction (PCR)) studies contradict each other making it difficult to determine the EBV etiology for breast cancer. In this present study, we performed a re-investigation of some of the known studies. To place our results in context, this study support the hypothesis that EBV is a cause of human breast cancer.

Epstein Bar Virus. a Main Cause of Hodgkin’s Lymphoma.

Authors: Ilija Barukčić
Comments: 7 Pages. Copyright © 2017 by Ilija Barukčić, Jever, Germany. Published by:

Epstein-Barr virus (EBV), a herpes virus which persists in memory B cells in the peripheral blood for the lifetime of a person, is associated with some malignancies. Many studies suggested that the Epstein-Barr virus contributes to the development of Hodgkin's lymphoma (HL) in some cases too. Despite intensive study, the role of Epstein-Barr virus in Hodgkin's lymphoma remains enigmatic. It is the purpose of this publication to make the proof the Epstein-Barr virus is a main cause of Hodgkin’s lymphoma (k=+0,739814235, p Value = 0,000000000000138).

Helicobacter Pylori – the Cause of Human Gastric Cancer.

Authors: Ilija Barukčić
Comments: 9 Pages. Copyright © 2016 by Ilija Barukčić, Jever, Germany. Published by Journal of Biosciences and Medicines, Vol.5 No. 2, p. 1-9. https://doi.org/10.4236/jbm.2017.52001

Background: Many studies documented an association between a Helicobacter pylori infection and the development of human gastric cancer. None of these studies were able to identify Helicobacter pylori as a cause or as the cause of human gastric cancer. The basic relation between gastric cancer and Helicobacter pylori still remains uncer-tain. Objectives: This systematic review and re-analysis of Naomi Uemura et al. available long-term, prospective study of 1526 Japanese patients is performed so that some new and meaningful inference can be drawn. Materials and Methods: Data obtained by Naomi Uemura et al. who conducted a long-term, prospective study of 1526 Japanese patients with a mean follow up about 7.8 years and endoscopy at enrolment and in the following between one and three years after enrolment were re-analysed. Statistical analysis used: The method of the conditio sine qua non relationship was used to proof the hypothesis without a helicobacter pylori infection no development of human gastric cancer. The mathematical formula of the causal relationship was used to proof the hypothesis, whether there is a cause effect relationship between a helicobacter pylori infection and human gastric cancer. Significance was indicated by a P value of less than 0.05. Results: Based on the data published by Uemura et al. we were able to make evidence that without a helicobacter pylori infection no development of human gastric cancer. In other words, a Helicobacter pylori infection is a conditio sine qua non of human gastric cancer. In the same respect, the data of Uemura et al. provide a significant evidence that a helicobacter pylori infection is the cause of human gastric cancer. Conclusions: Without a Helicobacter pylori infection no development of human gastric cancer. Hel-icobacter pylori is the cause (k=+0,07368483, p Value = 0.00399664) of human gastric cancer.
