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 ...
A Particle System with Explosions: Law of Large Numbers for the Density of Particles and the Blow-Up Time
(2012)
Consider a system of independent random walks in the discrete torus with creation-annihilation of particles and possible explosion of the total number of particles in finite time. Rescaling space and rates for diffusion/ ...
Design of chitosan-based particle systems: A review of the physicochemical foundations for tailored properties
(2020-12-15)
Chitosan-based particles are widely proposed as biocompatible drug delivery systems with mucoadhesive and permeation enhancing properties. However, strategies on how to modulate the intended biological responses are still ...
Characterization of the nanomorphology of polymer-silica colloidal nanocomposites using electron spectroscopy imaging
(Amer Chemical SocWashingtonEUA, 2005)
Stochastic variational approach applied to 2, 3 and 4 alpha particles
(Amer Inst Physics, 2011-01-01)
A stochastic variational method is applied to calculate the binding energies and root-mean-square radii of 2, 3 and 4 alpha particles using an S-wave Ali-Bodmer potential. The results agree with other calculations. We ...

AC Biosusceptometry as a Tool for Monitoring the Gastrointestinal Transit of Multiparticulate Drug Delivery System
(Springer, 2010-01-01)
Drug delivery systems based on natural polysaccharides, such as chitosan (CS) and pectin (PC), rather than on synthetic polymers, have been widely studied. Some reasons for that are low toxicity and costs and high ...
Kramers equation for a charged Brownian particle: the exact solution
(Elsevier B.V., 2005-09-15)
We report the exact fundamental solution for Kramers equation associated to a Brownian gas of charged particles, under the influence of homogeneous (spatially uniform) otherwise arbitrary, external mechanical, electrical ...
