A new approach to analysis of accumulation and enrichment of heavy metals in Danube River sediment along the Iron Gate reservoir in Serbia [PDF]
Concentrations of heavy metals (Cu, Zn, Pb, Cd) and long-lived radionuclides (U, Th, Cs) along the Iron Gate reservoir of the River Danube in Serbia were determined. In years 2005-2009, water and sediments were sampled at six sites along 200 km of the

Angular distribution and rotations of frame in vector meson decays into lepton pairs [PDF]
We discuss how the angular distribution of lepton pairs from decays of vector mesons depends on the choice of reference frame, and provide a geometrical description of the transformations of the coefficients of the angular distribution.

Development of effective algorithms for calculating current distribution coefficients of an electric power system [PDF]
Calculations of steady-state modes of a complex electric power system are significantly simplified if we use the coefficients of distribution of the setting currents.

Modification of Roughness Coefficients of Water Distribution Network Using Optimization Method [PDF]
Due to the breadth and complexity of water distribution networks, modeling of these networks is essential for proper utilization and proper network management. Determination of network coefficients is the more importance in network modeling.

Distribution dependent SDEs with singular coefficients [PDF]
Under integrability conditions on distribution dependent coefficients, existence and uniqueness are proved for McKean-Vlasov type SDEs with non-degenerate noise. When the coefficients are Dini continuous in the space variable, gradient estimates and Harnack type inequalities are derived.

Distribution of the second virial coefficients of globular proteins [PDF]
George and Wilson [Acta. Cryst. D 50, 361 (1994)] looked at the distribution of values of the second virial coefficient of globular proteins, under the conditions at which they crystallise. They found the values to lie within a fairly narrow range.

Estimating Coefficient Distributions in Random Coefficient Regressions
The model is \(Y_ j=a+(b+j)x_ j+e_ j\), \(j=1,2,\dots\) where \(E(b_ j)=E(e_ j)=0\), the \(b_ 1,e_ 1,b_ 2,e_ 2,\dots\) are independent and \(\{b_ 1,b_ 2,\dots\}\) as well as \(\{e_ 1,e_ 2,\dots\}\) are i.i.d. The authors study the estimation of the distribution of \(b_ j\) and \(e_ j\), respectively, for resampling purposes.
