Stability analysis of an eco-epidemiological model incorporating a prey refuge

The present paper deals with the problem of a predator-prey model incorporating a prey refuge with disease in the prey-population. We assume the predator population will prefer only infected population for their diet as those are more vulnerable. Dynamical behaviours such as boundedness, permanence, local and global stabilities are addressed. We have also studied the effect of discrete time delay on the model. The length of delay preserving the stability is also estimated. Computer simulations are carried out to illustrate our analytical findings

Peterodimenzijski kozmološki model struna u drugoj samotvornoj teoriji

In this paper we have constructed a five-dimensional string cosmological model in Barber\u27s (1982) second self-creation theory of gravitation. When the coupling constant becomes zero, the model degenerates into two different string cosmological models in Einstein\u27s theory corresponding to variable G and constant G. Some physical and geometrical properties of the model are discussed.U ovom smo radu razvili peterodimenzijski kozmološki model struna u okviru druge Barberove samotvorne teorije gravitacije. Kada konstanta vezanja postane jednaka nuli, model se pretvara u dva različita kozmološka modela struna u Einsteinovoj teoriji koji odgovaraju promjenljivom G i stalnom G. Raspravljaju se neka fizička i geometrijska svojstva modela

Kaluza-Kleinov FRW kozmološki model s krutom tekućinom u Lyrinoj mnogostrukosti

In this paper we made an attempt to construct a five-dimensional FRW stiff fluid cosmological model in Lyra manifold. This model reduces to curvature-free (k=0) expanding stiff fluid cosmological model. Some physical and geometrical properties of the model are discussed.Pokušali smo ustrojiti pet-dimenzijski Friedmann-Robertson-Walker kozmološki model s krutom tekućinom u Lyrinoj mnogostrukosti. Taj se model svodi na kozmološki model bez zakrivljenosti (k = 0) s krutom tekućinom i širenjem. Raspravljaju se neka fizička i geometrijska svojstva modela

Violation of Bell's inequality for phase singular beams

We have considered optical beams with phase singularity and experimentally verified that these beams, although being classical, have properties of two mode entanglement in quantum states. We have observed the violation of Bell's inequality for continuous variables using the Wigner distribution function (WDF) proposed by Chowdhury et al. [Phys. Rev. A \textbf{88}, 013830 (2013)]. Our experiment establishes a new form of Bell's inequality in terms of the WDF which can be used for classical as well as quantum systems.Comment: 7 pages, 9 figures and 1 tabl
