Exploring dynamics in living cells by tracking single particles
(Springer, 2007-05-25)
In the last years, significant advances in microscopy techniques and the introduction of a novel technology to label living cells with genetically encoded fluorescent proteins revolutionized the field of Cell Biology. Our ...
Photochemistry of single particles using acoustic levitation coupled with Raman microspectrometry
(John Wiley & Sons Ltd, 2017-08)
The photoreactivity of single particles with atmospheric interest was studied by using an acoustic levitation system coupled to Raman microspectrometry. Both, inorganic and organic single particle phototransformation has ...
Pairing in the BCS and LN approximations using continuum single particle level density
(Elsevier Science, 2017-04)
Understanding the properties of drip line nuclei requires to take into account the correlations with the continuum spectrum of energy of the system. This paper has the purpose to show that the continuum single particle ...
Occupation probabilities of single particle levels using the microscopic interacting boson model: Application to some nuclei of interest in neutrinoless double-beta decay
(2016)
We have developed a new method to calculate the occupancies of single particle levels in atomic nuclei. This method has been developed in the context of the microscopic interacting boson model, in which neutron and proton ...
Single-particle momentum distributions of Efimov states in mixed-species systems
(2013-06-04)
We solve the three-body bound-state problem in three dimensions for mass imbalanced systems of two identical bosons and a third particle in the universal limit where the interactions are assumed to be of zero range. The ...
Macromolecule Particle Picking and Segmentation of a KLH Database by Unsupervised Cryo-EM Image Processing
(Facultad de Medicina y Ciencia, 2019)
Segmentation is one of the most important stages in the 3D reconstruction of macromolecule structures in cryo-electron microscopy. Due to the variability of macromolecules and the low signal-to-noise ratio of the structures ...
Dynamic symmetry loss of high-frequency hysteresis loops in single-domain particles with uniaxial anisotropy
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
Understanding how magnetic materials respond to rapidly varying magnetic fields, as in dynamic hysteresis loops, constitutes a complex and physically interesting problem. But in order to accomplish a thorough investigation, ...
Light-particle single ionization of argon: Influence of the projectile charge sign
(American Physical Society, 2009-07)
The ionization of the 3p orbital of argon by incident electrons and positrons is studied by means of the post version of the continuum distorted wave–eikonal initial-state model. Results are presented at both 200 and 500 ...
Evolution equation for tagged-particle density and correlations in single-file diffusion
(Amer Physical Soc, 2013-08)
We derive and study a theoretical description for single-file diffusion, i.e., diffusion in a one-dimensional lattice of particles with hard core interaction. It is well known that for this system a tagged particle has ...
