Soliton formation by decelerating interacting Airy beams
(Optics Express, 2015)
We demonstrate a new type of soliton formation arising from the interaction of multiple two-dimensional Airy beams in a nonlinear medium. While in linear regime, interference effects of two or four spatially displaced Airy ...
Excitation of guided waves in materials with negative refraction
(Elsevier, 2008)
We study, both analytically and numerically, electromagnetic beam transmission through a layered structure that includes a waveguide slab of metamaterial with negative refraction. The resonant excitation of the leaky guided ...

Effect of subclinical and overt form of rat maternal hypothyroidism on offspring endochondral bone formation
(Faculty of Veterinary Medicine, University of Belgrade, Serbia, 2018)
Maternal hypothyroidism in its overt form affects skeletal development of the offspring,
but these data are not available for the subclinical form which is becoming very frequent
among pregnant women. We hypothesized ...
Activity Coefficients of the System {yKCl + (1 − y)KH2PO4}(aq) at T = 298.15 K Determined by Cell Potential Measurements
(ACS Publications, 2023)
: Zero-current cell potential measurements were used
to determine the solution activity coefficient in a ternary system
{yKCl + (1 − y) KH2PO4}(aq) at temperature T = 298.15 K. The
cell of the type K−ISE|KCl(mKCl), ...
Duration of ‘peeks’ in ducks: how much time do Pochard Aythya ferina spend with eye open while in sleeping posture?
(Bird Study/Ringing & Migration, 2020)
‘Peeks’, or keeping an eye open, in wintering Pochard Aythya ferina, while in sleeping posture, were relatively brief, typically (66% of observations) lasting less than 1s; however, in 37% of individuals some peeks lasted ...
Ecological Potential Asseessment of Sava Lake Based on Fish Community Composition: preliminary results
(Serbian Water Pollution Control Society, 2014)
Two-way reaction of versatile peroxidase with artificial lignin enhances low-molecular weight fractions
(John Wiley and Sons Inc, 2023)
In recent years, versatile peroxidase (VP) has emerged as a promising enzyme for biotechnological applications, as it can oxidize lignin without the external mediators. To gain insights into the breakdown process of ...
