Cancer as a phase transition

- 1 Comment

Without a theoretical basis
experimentalists are wandering around blindly in the dark. Unfortunately, this
is often the situation in the medical sciences. That is why interdisciplinary research is so important.

The recent article:
‘Cancer as a dynamical phase transition’ by Davies, Demetrius, and Tuszynski published in Theoretical Biology and Medical
Modelling
is an excellent example of such
research. In their conclusions the authors write: “This new perspective points
up certain features that are often ignored in therapeutic approaches. In terms
of therapeutic insights that may be gained from the application of the concept
of a phase transition, the long-range correlation effect, which is a
characteristic property of systems undergoing phase …

The Game of Choosing – models and software developed to simulate
selection or election processes
– has a broad spectrum of applications to both biomedical systems and socio-economical
systems; analogous to econophysics it may be called econobiophysics (Klonowski W, Pierzchalski M, Stepien P,
and Stepien RA: Econobiophysics – game of choosing. Model of selection or
election process with diverse accessible information. Nonlinear Biomedical Physics 2011, 5:7)
.

If a subject even has an initial
slight preference towards a given object then these
simulations demonstrate that, if
information passed on by a direct or indirect object’s exposition (presentation
of the object) exerts a favorable impact on the subject, it is enough …

Fractal method of assessment of histological images

- 0 Comments

The fractal method of analysis and
assessment of histological images
(W.Klonowski, R.Stepien, and 
P.Stepien, 2010)
can play a very important role in the future
diagnostic practice. It may be important also in robotic surgery.

 

Histological images from the border
area of the tumor must be now evaluated by an anatomo-pathologist. However, it
is very likely that when the automatic analysis achieves more accuracy,
the human role in the tissue sample evaluation will become limited. The doctor
will always supervise and control the robot surgery and the histological  diagnosis, but the automatic assessment can
be more accurate and objective.

From miliseconds to ’till death pulls apart’

  W. Klonowski (2004) 
put forward the hypothesis that important difference between feelings (emotional processes) and thoughts (rational processes) is in the
characteristic time scales of those two kinds of brain processes and that this
may be modeled using methods of nonlinear 
dynamics. Like any complex dynamical system human brain is characterized
in any moment by momentary values of its state variables and so the brain state
may be characterized by a point in a multi-dimensional phase space with
appropriately defined coordinates. Then psycho-physiological processes in the
brain may be represented by some trajectories in this space. Since psychophysical
processes occurring in the brain continuously change brain’s phase space, rational
processes that are much …

Welcome to the Nonlinear Biomedical Physics blog. We hope this site will become the forum for demonstrating how nonlinear methods can shed new light on biological phenomena and medical applications. The blog is also intended to bridge the technical, mathematical and cultural divides between the physical disciplines where these methods are being developed and the audience for their use in the biological and medical sciences.

We welcome short pieces on interesting topics such as recent research papers, new methodologies, policy directions, funding opportunities and upcoming meetings. Blogs on all aspects of nonlinearity in medical and biological sciences are welcome. Bloggers for this site come from a wide range of backgrounds, like physics and biomedical engineering as well as medicine …
