Evolution of transcriptional enhancers and animal diversity
(The Royal Society, 2013-12)
Deciphering the genetic bases that drive animal diversity is one of the major challenges of modern biology. Although four decades ago it was proposed that animal evolution was mainly driven by changes in cis-regulatory DNA ...
Emerging experimental strategies for studies on inhomogeneous nanomaterials: Exploring electronics, atomic structure and properties by synchrotron X-Ray-based techniques
(Centro de Estudios sobre Ciencia, Desarrollo y Educación Superior, 2020-06-12)
Through representative examples, we illustrate the strategic value of synchrotron X-ray-based techniques for nanomaterial characterization, especially for inhomogeneous nanomaterials. These examples are used to describe ...
Characterizing points on discontinuity boundary of Filippov systems
(ACTA Press, 2008-01-01)
In this paper, we presented a basic methodology to understand the behavior of discontinuous piecewise smooth autonomous systems (denominated Filippov systems) in the planar neighborhood of the discontinuity boundary (DB). ...
Inequality between size and charge in spherical symmetry
(American Physical Society, 2016-02-15)
We prove that, for a charged spherically symmetric body, twice the radius is always strictly greater than the charge of the body. We also prove that this inequality is sharp. Finally, we discuss the physical implications ...
Routh reduction for first-order Lagrangian field theories
(Springer, 2018-11-22)
We present a reduction theory for first-order Lagrangian field theories which takes into account the conservation of momenta. The relation between the solutions of the original problem with a prescribed value of the momentum ...
Graphical analysis of current-voltage characteristics in memristive interfaces
(American Institute of Physics, 2017-04)
A graphical representation of current-voltage (IV) measurements of typical memristive interfaces at constant temperature is presented. This is the starting point to extract relevant microscopic information of the parameters ...
Resonances on metallic compound transmission gratings with subwavelength wires and slits
(Elsevier Science, 2006-12)
We investigate the response of gratings formed by subwavelength wires in a dielectric medium. For gratings with a single wire per period, most of the incident power is transmitted through the structure. If the distance ...
