Physics Letters, 1965 Due to small nonlinearities, an ensemble of oscillators may exhibit echoes when subjected to multiple pulses of radiation near their resonant frequency. Cyclotron echoes from gyrating charged particles is discussed as an example.

Towards a corpuscular model of optical phenomena [PDF]
, 2011 This thesis presents a collection of event-by-event models that simulate fundamental optical experiments. The simulation approach is completely based on the experimental facts.

Emerging experimental and computational methods for studying redox‐regulated structural transitions
FEBS Letters, EarlyView.Redox reactions can reshape proteins and alter how they behave in cells, with important consequences for health and disease. This review explores emerging experimental and computational approaches for discovering these redox‐sensitive protein switches, revealing their structural effects, and predicting their behavior, opening new opportunities to ...

FEBS Letters, EarlyView.How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

QUAL ONTOLOGIA PARA O EMPIRISMO CONSTRUTIVO?
Princípios, 2014 Is there an ontological question relative to van Fraassen’s Constructive Empiricism? It seems so, despite this philosophical position, a reference for contemporary Empiricism, presenting itself as an epistemological thesis.

Implementation of reflective model of educational practice in the modern Finnish school
Освітній вимір, 2020 The article considers the example of a country whose educational system has absorbed the ideas of philosophical concepts of critical thinking of I. Kant and M. Lipman. After all, thanks to the dynamic integration processes in the world, we pay attention

Bogen and Woodward’s data-phenomena distinction, forms of theory-ladenness, and the reliability of data [PDF]
, 2009 Some twenty years ago, Bogen and Woodward challenged one of the fundamental assumptions of the received view, namely the theory-observation dichotomy and argued for the introduction of the further category of scientific phenomena.

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation
FEBS Letters, EarlyView.Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...
