MK simulation of electromagnetic calorimeter by means GEANT4 is carried out 
for soft photon registration in pp and pA interactions. The studying of excess of 
such photon yield is planned to fulfill at U-70 accelerator of IHEP, Protvino, 
Russia.

The important task of any experimental project at the reconstruction procedure is 
the alignment. It is necessary to provide the correcting geometry of setup for 
reconstruction of tracks in space and the finding of their characteristics. For these 
purposes the programme packet based on ideas of Millepede packet have been 
designed. The linear and nonlinear parameters of alingment can be finded 
through few iteration. 
 
 
On electromagnetic interaction of Majorana fermions

We evaluate the interaction of Majorana fermion (e.g. WIMP) with ordinary 
nucleus by electromagnetic field. It may be interesting for the search of dark 
matter particles.

We present the study of interplay between pulsed beams in nonlinear media. 
Particular attention is paid to the effect of total reflection of signal from the 
reference. Cascade three-wave interactions at a large phase mismatch create the 
cross-modulation of signal refractive index. We give the results of numerical 
 43
simulation of three-wave equations and analyze the formation of the trajectories 
of the pulsed beams centers in the space-time domain. The results of the 
collisions depend on initial conditions: pulse time delay, angle of beam 
intersection, the effect of synchronization in space and time, the ratio of their 
lengths, widths and amplitudes.

Contemporary idea of public health care is based on servicing people in the net of 
clinics and hospitals. This idea proved good in XXth century, but now it doesn't 
answer modern needs and is be revised. One of the most important directions of 
changing approach to health care is monitoring physiology, physical activity and 
illness by a person itself. Rapid development of electronics, personal 
communications, computer science, passive detectors of physiological 
parameters, and active means of self-treatment adds to this approach and shifts 
the focus of health care to the man and to monitoring his state by himself. In this 
context, wireless networks of sensors placed in, on and around the human body to 
observe its state, have great potential for future treatment technologies. BANs 
support a vast field of medicine and consumer electronics applications. For 
example, BANs allow long-time remote monitoring of patient's health without 
restricting his normal activities. Research in the field of BANs began in 1960s. 
However, only since the beginning of 2000s BANs are being implemented in 
medical practice with the appearance and massive use of personal 
communications. In the report, requirements for wireless communication devices 
for WBANs are discussed. Ultra wide band direct chaotic transceivers are 
described and prospects of their use in wireless sensor networks of the new 
standard IEEE 802.15.6 (WBAN) are analyzed. 
 
 
Finite-dimensional models of diffusion chaos

Some parabolic systems of the reaction–diffusion type exhibit the phenomenon of 
diffusion chaos. Specifically, when the diffusivities decrease proportionally, 
while the other parameters of a system remain fixed, the system exhibits a chaotic 
attractor whose dimension increases indefinitely. Various finite-dimensional 
models of diffusion chaos are considered that represent chains of coupled
