After a brief overview of classical techniques used to explore cardiac rhythm variability, we show how the DFA method can help diagnose heart failure.

A major challenge in biological physics is the analysis of time series that are typically highly nonstationary. Viswanathan et al. (Phys. Rev. E 55 (1) (1997) 845–899) using techniques based on the Fano factor and the Allan factor functions, as well as on detrended fluctuation analysis showed...

Polyelectrolytes are of great importance in different branches of chemistry and biology. DNA is a very good example of a polyelectrolyte of biological relevance. In this paper, we describe DNA solutions in the presence of multivalent salts and amphiphiles. After thermodynamic equilibrium is...

An introduction to Biological Physics is provided by three applications of Statistical Mechanics to current problems of biological interest. They are the possibility of lateral phase separation in the plasma membrane, the design of a vesicle sensitive to its environment which could be used for...

We discuss various features of the trajectories of spider monkeys looking for food in a tropical forest, as observed recently in an extensive in situ study. Some of the features observed can be interpreted as the result of social interactions. In addition, a simple model of deterministic walk in...

Without any doubt, rapid digital technology advancement has a significant impact on the work of researchers in all scientific disciplines. Against this background, the major objective of this article is to give a brief overview of mobile device applications that enable continuous and seamless...

One of the most influential services provided on the internet is an online social networking site. With increasing competition in global and regional markets, having a brand is not a choice, but an inevitable necessity that in the case of negligence, there could be a reduction in the product...

Paper aimed to consider of approaches to big data (social network content) utilization for understanding of social behavior in the conflict zones, and analysis of dynamics of illegal armed groups. Analysis directed to identify of underage militants. The probabilistic and stochastic methods of...

We are living in a world of vast information. The means of the Internet allow access to diverse sources of information, with social media and Internet of Things technologies significantly expanding the informational ecosystem. With the use of social media, it is easy for ‘like-minded' people...
