BACKGROUND/AIM
Increasing number of epidemiological and clinical studies to date showed that the pandemic influenza A (H1N1) 2009, by its characteristics, significantly differs from infection caused by seasonal influenza. Therefore, the information about clinical spectrum of manifestations, risk factors for severe form of the disease, treatment and outcome… (More)

In this work, generalizing our previous results, we determine in an original and the simplest way three most important thermodynamical characteristics (Bekenstein-Hawking entropy, Bekenstein quantization of the entropy or (outer) horizon surface area and Hawking temperature) of Kerr-Newman black hole. We start physically by assumption that circumference of… (More)

In this work we show that single horizon black hole behaves as a ”laser”. It is in many aspects conceptually analogous to Corley and Jacobson work on the two horizon black hole ”laser”. We started by proposition that circumference of the black hole horizon holds the natural (integer) quantum number of corresponding reduced Compton’s wave length of some… (More)

It is shown that all simple ecological, i.e. population dynamical equations (unlimited exponential population growth (or decrease) dynamics, logistic or Verhulst equation, usual and generalized Lotka-Volterra equations) hold a symmetry, called CEPT symmetry. Namely, all simple ecological dynamical equations are invariant (symmetric) in respect to successive… (More)

In this work we consider a simple, approximate, tending toward exact, solution of the system of two usual Lotka-Volterra differential equations. Given solution is obtained by an iterative method. In any finite approximation order of this solution, exponents of the corresponding Lotka-Volterra variables have simple, time polynomial form. When approximation… (More)

We examine a simple theoretical model to estimate (by fine tuning condition) the value of the cosmological constant. We assume, in analogy with holographic principle, that cosmological constant, like classical surface tension coefficient in a liquid drop, does not correspond to a volume (bulk) vacuum mass (energy) density distribution, but rather to the… (More)

In this work we suggest and consider an original, simple mathematical model of a ”quasirapid” extinction population dynamics. It describes a decrease and final extinction of the population of one prey species by a ”quasi-rapid” interaction with one predator species with increasing population. This ”quasi-rapid” interaction means ecologically that prey… (More)

In this work we suggest, without detailed mathematical analysis, a hypothesis on the physical meaning of cosmological constant. It is primarily based on a conceptual analogy with energy characteristics of the crystal lattice structure, i.e. energy zones theory in solid state physics. Namely, according to some theories (holographic principle, emergent… (More)

In this work we consider time reversal of the increasing geometrical progression of the population of a simple biological species without any enemies (predators) in the appropriate environment with unlimited resources (food, territory, etc.). It is shown that such time reversal corresponds to appearance of the cannibalism, i.e. self-predaciousness or… (More)

In this work we present a simple, approximate method for analysis of the basic dynamical and thermodynamical characteristics of Kerr-Newman black hole. Instead of the complete dynamics of the black hole self-interaction we consider only such stable (stationary) dynamical situations determined by condition that black hole (outer) horizon circumference holds… (More)
