LIGHT ABERRATION IN OPTICAL ANISOTROPIC SINGLE-AXIS MEDIUM

open access: yesEast European Journal of Physics, 2017
The entrainment of the light flux by a uniaxial anisotropic medium and its influence on the measurement of stellar aberration are analyzed. The influence of the entrainment of the light flux by an isotropic medium on the measurement of stellar aberration

Human flaws and logical tools in engineering

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract This paper explores the limitations of human cognition, especially in engineering research, emphasizing the need for mathematical models and methods to guide decision‐making and theory validation. While human cognition excels in certain tasks, it is prone to biases that can distort our understanding.

Continuous Flow Block Copolymer Nanoaggregate Synthesis and Their Flow Dialysis Purification

open access: yesChemistry–Methods, EarlyView.
This work details the methodology for the synthesis of block copolymer nanoparticles through continuous flow self‐assembly and purification via flow dialysis. Nanoaggregates are formed by mixing block copolymer solutions in THF with water, followed by dialysis to eliminate excess solvent.

First‐order Sobolev spaces, self‐similar energies and energy measures on the Sierpiński carpet

open access: yesCommunications on Pure and Applied Mathematics, EarlyView.
Abstract For any p∈(1,∞)$p \in (1,\infty)$, we construct p$p$‐energies and the corresponding p$p$‐energy measures on the Sierpiński carpet. A salient feature of our Sobolev space is the self‐similarity of energy. An important motivation for the construction of self‐similar energy and energy measures is to determine whether or not the Ahlfors regular ...

Fluorescence Lifetime Imaging Microscopy Analysis of Isolated Melanosomes

open access: yesChemPhysChem, EarlyView.
Using fast fluorescence lifetime imaging microscopy, the study tracks isolated bovine and porcine melanosomes during 60 min of 515 nm laser exposure. Two decay components lengthen progressively, while amplitude ratios shift, evidencing rapid photo‐oxidative and structural alterations of melanin.
