This paper introduces “Contingency table analysis”, a freely available menu-driven add-in program for Microsoft EXCEL, written in Visual Basic for Applications (VBA), for basic univariate and bivariate statistical analyses of contingency tables. The program provides mod...

Abstract One may predict a quasicrystal structure starting from electrons and quantum mechanics, as approximated by interatomic pair potentials calibrated with ab initio total-energy calculations, combined with the experimentally known composition and lattice constants....

A search for squarks of R-parity violating supersymmetry is performed in $ep$ collisions at HERA using H1 1994 $e^+$ data. Direct single production of squarks of each generation by $e^+$-quark fusion via a Yukawa coupling $\lambda'$ is considered. All possible R-parity ...

The article reviews the potential of light guide system equipped by a concentrator device capturing daylight applicable for illumination of building interiors and presents results of experiments on performance of its prototype. The main goal is focused on the comparison...

The study of symmetric configurations $v_3$ with block size 3 has a long and rich history. In this paper we consider two colouring problems which arise naturally in the study of these structures. The first of these is weak colouring, in which no block is monochromatic; ...

Roman law is considered to be one of the most influential elements of the continental legal culture. However, rapid technological development and changing social and economic situation bring new challenges for principles tested during the centuries. Consumer protection;...

The idea of sustainable development links business, environmental and social objectives into one integrated effort aiming to meet a common goal. Due to the influence of current developments in customer behaviour companies revise their business strategies towards more su...

We investigate the phase diagram of ${\mathrm{TmB}}_{4}$, an Ising magnet on a frustrated Shastry-Sutherland lattice, by neutron diffraction and magnetization experiments. At low temperature we find N\'eel order at low field, ferrimagnetic order at high field, and an in...

Abstract Background Colorectal cancer (CRC) is one of the leading cancer with the 55% survival rate. The analysis of tumor microenviroment in fresh surgical samples by flow cytometry focuses on the presence of immune cells. However, no direct access to fresh tumor sampl...
