Published in 2019 at "Foundations of Physics"

DOI: 10.1007/s10701-018-00233-z

Abstract: We investigate the evolution of linear density contrasts obtained with respect to a homogeneous spatially flat Friedman-Lemaître–Robertson–Walker (FLRW) background by solving the density contrast equations governed by Newtonian and MONDian force laws using symmetry-based approach.… read more here.

Published in 2018 at "Cortex"

DOI: 10.1016/j.cortex.2018.09.005

Abstract: Our vision systems utilize attention to process dynamic visual information everyday. Multiple object tracking (MOT) is widely used for studying sustained attention in dynamic environments. Previous research reported inter-target grouping based on feature similarity (e.g.,… read more here.

Published in 2020 at "Economics Letters"

DOI: 10.1016/j.econlet.2020.109662

Abstract: Abstract We study the performance of tests of distributional symmetry based on the coefficient of skewness and on L-moments and present a bootstrap implementation of such tests that is suitable in time series applications. We… read more here.

Published in 2022 at "Soft matter"

DOI: 10.1039/d2sm00840h

Abstract: Chromatin - the functional form of DNA in the cell - exists in the form of a polymer immersed in a nucleoplasmic fluid inside the cell nucleus. Both chromatin and nucleoplasm are subject to active… read more here.

Published in 2022 at "2D Materials"

DOI: 10.1088/2053-1583/accc43

Abstract: We present a symmetry-based systematic approach to explore the structural and compositional richness of two-dimensional materials. We use a ‘combinatorial engine’ that constructs candidate compounds by occupying all possible Wyckoff positions for a certain space… read more here.

Published in 2020 at "Physical Review B"

DOI: 10.1103/physrevb.101.245128

Abstract: Determining the topological phases in crystalline systems requires a complete set of topological invariants, whose definition and evaluation is, in general, a complicated task. Symmetry-based indicators, such as the Fu-Kane formula for inversion-symmetric topological insulators,… read more here.

Published in 2023 at "Optics letters"

DOI: 10.1364/ol.488365

Abstract: Symmetry-based tailoring of photonic systems recently heralded the advent of novel concepts, such as photonic topological insulators and bound states in the continuum. In optical microscopy systems, similar tailoring was shown to result in tighter… read more here.

Published in 2022 at "International Journal of Environmental Research and Public Health"

DOI: 10.3390/ijerph20010476

Abstract: The COVID-19 pandemic has revealed new features in terms of substantial changes in rates of infection, cure, and death as a result of social interventions, which significantly challenges traditional SEIR-type models. In this paper we… read more here.
