Based on observations over an alpine glacier, we investigate the turbulent flux dissimilarity between momentum and sensible heat transfer in a stably stratified katabatic flow. The flux correlation coefficient RF is employed as a measure of variable

In this paper, we have analysed the latest data from NO$\nu$A and T2K with the Lorentz invariance violation along with the standard oscillation hypothesis. We have found that the NO$\nu$A data cannot distinguish between the two hypotheses at $1\, \si

Artykuł przedstawia zainteresowania inżynierskie Isaaca Newtona, w tym niektóre z jego wynalazków technicznych. Temat ten nie doczekał się jak dotąd szerszego i pogłębionego opracowania. W artykule poruszono młodzieńcze pasje Newtona na tl

We describe the dynamics of the 3-dimensional competitive Lotka–Volterra systems $$ \dot{x}=x(a-x-y-z),\quad \dot{y}=y(b-x-y-z),\quad \dot{z}=z(c-x-y-z), $$ providing the phase portraits for all the values of the parameters $a$ , $b$ and $c$ with $

We describe the process of constructing a positive solution of the homogeneous Wiener–Hopf integral equation in an octant in a special $$($$ conservative $$)$$ case. Applying the obtained general results to the homogeneous stationary Peierls equati

This paper formulates and analyzes a predator-prey model with disease in the prey. Mathematical analysis of the model system concerns the existence, uniqueness and uniform boundedness of solutions in the positive octant. The threshold condition for e

Two new cyclic diarylheptanoids, casuaritriol A (1) and casuaritriol B (2), were isolated from the EtOAc extract of litters (including branches and leaves) of Casuarina equisetifolia, along with a new triterpene casuariene (3), and two known compound

A three-dimensional model of cancer growth showing the interaction of immune, tumor and host (healthy) cells is considered. This model was proposed by L.G. de Pillis and A. Radunskaya and is based on the earlier work of Kuznetsov et al. The equilibri

The weaving machine’s reliability is assessed using newly introduced fuzzy numbers. The fuzzy numbers introduced in this study give a better method to improve the reliability than other techniques. Pendant Fuzzy Number, Hexant Fuzzy Number, and Oct

We propose a linear seesaw model to realise light Dirac neutrinos within the framework of $A_4$ discrete flavour symmetry. The additional fields and their transformations under the flavour symmetries are chosen in such a way that naturally predicts t
