#### Closed-form formulae for the derivatives of trigonometric functions at rational multiples of pi

(Applied Mathematics Letters, 2009)

In this sequel to our recent note [D. Cvijovic, Values of the derivatives of the cotangent at rational multiples of pi, Appl. Math. Lett. http://dx.doi.org/10.1016/J.aml.2008.03.013] it is shown, in a unified manner, by ...

#### Wake effect in interactions of fast ions with supported two-dimensional electron gas

(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2010)

We study the interactions of fast charged particles with a two-dimensional electron gas supported by an insulating substrate, describing its high-frequency plasmon excitations by a two-fluid hydrodynamic model with the ...

#### Study on electronic properties of alpha-, beta- and gamma-AlH3 - The theoretical approach

(Computational Materials Science, 2017)

AIH(3) polymorphs (alpha-, beta-, gamma-) are highly promising materials for hydrogen storage and hydride electronics applications. Given the recent developments in the synthesis and hydrogen desorption approaches, here ...

#### Closed-form summations of certain hypergeometric-type series containing the digamma function

(Journal of Physics. A: Mathematical and Theoretical, 2008)

Recently, interesting novel summation formulae for hypergeometric-type series containing a digamma function as a factor have been established by Miller (2006 J. Phys. A: Math. Gen. 39 3011 - 20) mainly by exploiting already ...

#### Closed-form summation of two families of finite tangent sums

(Applied Mathematics and Computation, 2008)

In our recent paper with Srivastava [D. Cvijovic, H.M. Srivastava, Summation of a family of finite secant sums, Appl. Math. Comput. 190 (2007) 590-598] a remarkably general family of the finite secant sums was summed in ...

#### Investigation of the projectile atomic number influence to the total sputtering yield in the keV energy region

(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2008)

The non-monotonous dependence of the total sputtering yield on the projectile atomic number, which is unexpected in the frame of the Sigmund linear cascade theory, is investigated using Monte Carlo simulations (program ...

#### Numerical simulation of photothermal effects in solids with inhomogeneous thermal properties

(Journal of Physics. D: Applied Physics, 1999)

A numerical simulation procedure for the calculation of surface temperature in thermally inhomogeneous solids induced by a harmonically modulated external heat source is presented. The procedure is based on the separation ...

#### Angiotensin II type 1 receptor gene polymorphism and essential hypertension in Serbian population

(Clinica Chimica Acta, 2003)

Essential hypertension is considered to be a multifactorial trait resulting from the combined influence of environmental and genetic determinants. Due to the controversial results about the role of the ATR1 gene locus in ...

#### On symmetric breather collisions in lattices with saturable nonlinearity

(European Physical Journal B. Condensed Matter and Complex Systems, 2006)

Symmetric collisions of two discrete breathers in the lattice with saturable nonlinearity are investigated. The strong correlation of the collision properties and the parameters of colliding breathers (power, velocity, and ...

#### Thermodynamic limit for the Ising model on the Cayley tree

(Physica A: Statistical Mechanics and Its Applications, 2005)

While the Ising model on the Cayley tree has no spontaneous magnetization at nonzero temperatures in the thermodynamic limit, we show that finite systems of astronomical sizes remain magnetically ordered in a wide temperature ...
