Life is considered something different from non-living things, but no single driving force can account for all the different aspects of life, which consists of different levels of hierarchy, such as metabolism, cell physiology, multi-cellular development and organization, population dynamics, ecosystem, and evolution. Although free energy is evidently the driving force in biochemical reactions,...

Entropy is a concept that was derived in the nineteenth century during the study of thermodynamic systems. Entropy exists in all systems, nonliving and living, that possess free energy for doing work. As system energy declines, entropy increases. Entropy has precise mathematical and statistical definitions, but can be approximately defined as the degree of disorder or uncertainty in a system. I...

predatory damsel bug, nabis pseudoferus remane has a high density in the alfalfa fields and feeds on different types of prey. in this study, biological properties and life table statistics of n. pseudoferus by feeding on melon aphids have been determined under controlled conditions (at 25±1˚c, 60±10% relative humidity and under a photoperiod of 16h light/ 8h dark). data analysis carried out bas...

Background and purpose: One of the most important subjects of the science of demography that is demanded by socio-economics planners, is the life table. The outline of this table- life expectancy- shows the change process of this index during time and consequently the health system performance. Material and Methods: In fact, the study is a epidemiologic explanation and we collected its relatin...

It is an oft-quoted fact that there is much in common between the fields of music and mathematics. This paper seeks to examine that commonality through the use of information theory techniques, specifically, entropy as defined by Shannon. The analysis will be presented in the form of an authentication problem with an entropy table being constructed and presented for a specific composer. Time al...

In many life-testing and reliability studies, the experimenter might not always obtain complete information on failure times for all experimental units. One of the most common censoring schemes is progressive type-II censoring. The aim of this paper is characterizing the parent distributions based on Shannon entropy of progressive type-II censored order statistics. It is shown that the equality...
