Pareto optimality, economy–effectiveness trade-offs and ion channel degeneracy: improving population modelling for single neurons

open access: yesOpen Biology, 2022
Neurons encounter unavoidable evolutionary trade-offs between multiple tasks. They must consume as little energy as possible while effectively fulfilling their functions. Cells displaying the best performance for such multi-task trade-offs are said to be

Experimentation with Animals: A Key Aspect of the 3Rs. The Genetic Quality [PDF]

open access: yes, 2019
The genetic quality of laboratory animals is essential for reproducibility of scientific research. Working with animals of certifiedgenetic quality is still a pending issue in Argentina due to the lack of routine genetic controls, of information on the ...

A proposed framework for holding intensive 3Rs workshops in laboratory animal science

open access: yesLaboratory Animal Research, 2022
Principles of 3Rs are the backbone of today’s animal research. Applying 3Rs in practice requires proper education and training. Although this could be achieved via long-term courses ranging from several weeks to years, in some circumstances a short-term ...

Unified ethical principles and an animal research ‘Helsinki’ declaration as foundations for international collaboration

open access: yesCurrent Research in Neurobiology, 2022
Ethical frameworks are the foundation for any research with humans or nonhuman animals. Human research is guided by overarching international ethical principles, such as those defined in the Helsinki Declaration by the World Medical Association. However,

Approximate analytical calculations of photon geodesics in the Schwarzschild metric [PDF]

open access: yes, 2016
We develop a method for deriving approximate analytical formulae to integrate photon geodesics in a Schwarzschild spacetime. Based on this, we derive the approximate equations for light bending and propagation delay that have been introduced empirically.
