On a close to symmetric system of difference equations of second order
(Springer Nature, 2015-12-29)
Closed form formulas of the solutions to the system of difference equations of the second order are found. The domain of undefinable solutions to the system is described.
On a product-type system of difference equations of second order solvable in closed form
(BioMed Central, 2015-10-12)
Sufficient conditions for solving a system of difference equations of second order in closed form are given. Moreover, sufficient conditions for existence of periodic solutions and asymptotic stability of solutions are ...
Boundedness character of a fourth-order system of difference equations
(Springer Nature, 2015-12-01)
Sufficient conditions for boundedness character of solutions of a fourth-order system of difference equations is given.
A multi-mode cantilever singular point detection using adaptive hypothesis testing
(IOP Publishing, 2015-10-05)
Fundamental analysis of a multi-mode model of the atomic force microscope cantilever shows that at some points; called here singular points, the mode is vanished. Consequently, the order of the input/output behavior is ...

Papillomavirus infection of roe deer in the Czech Republic and fibropapilloma-associated levels of metallothionein, zinc, and oxidative stress
(University of Veterinary and Pharmaceutical Sciences, 2015-06-01)
The present study aimed at the aetiological diagnosis of skin tumours of roe deer (Capreolus capreolus) in the Czech Republic. A total of 33 roe deer specimens showing skin masses were sampled for histopathology, virus ...
Quantitative phase imaging through scattering media by means of coherence-controlled holographic microscope
A coherence-controlled holographic microscope (CCHM) enables quantitative phase imaging with coherent as well as incoherent illumination. The low spatially coherent light induces a coherence gating effect, which makes ...
Multimode fibre: Light-sheet microscopy at the tip of a needle
(Springer Nature, 2015-12-14)
Light-sheet fluorescence microscopy has emerged as a powerful platform for 3-D volumetric imaging in the life sciences. Here, we introduce an important step towards its use deep inside biological tissue. Our new technique, ...
Simultaneous Automatic Electrochemical Detection of Zinc, Cadmium, Copper and Lead Ions in Environmental Samples Using a Thin-Film Mercury Electrode and an Artificial Neural Network
In this study a device for automatic electrochemical analysis was designed. A three electrodes detection system was attached to a positioning device, which enabled us to move the electrode system from one well to another ...
Exposure to 17 beta-Oestradiol Induces Oxidative Stress in the Non-Oestrogen Receptor Invertebrate Species Eisenia fetida
Background The environmental impacts of various substances on all levels of organisms are under investigation. Among these substances, endocrine-disrupting compounds (EDCs) present a threat, although the environmental ...
