Entanglement entropy between real and virtual particles in ϕ 4 quantum field theory
(American Physical Society, 2015-04)
The aim of this work is to compute the entanglement entropy of real and virtual particles by rewriting the generating functional of ϕ4 theory as a mean value between states and observables defined through the correlation ...
Particle creation in a f(R) theory with cosmological constraints
(Springer, 2014-04-01)
In this paper we study the creation of super-massive real scalar particles in the framework of a f (R) = R - beta/R-n modified gravity theory, with parameters constrained by observational data. The analysis is restrict to ...
PARTICLES OF ALUMINUM METAPHOSPHATE CONTAINING CLOSED PORES - PREPARATION, CHARACTERIZATION AND OPTICAL-PROPERTIES
(Elsevier Science BvAmsterdamHolanda, 1993)
Fuzzy community structure detection by particle competition and cooperation
(2013-04-01)
Identification and classification of overlapping nodes in networks are important topics in data mining. In this paper, a network-based (graph-based) semi-supervised learning method is proposed. It is based on competition ...

Determination of particle concentration in the breathing zone for four different types of office ventilation systems
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
Many factors affect the airflow patterns, thermal comfort, contaminant removal efficiency and indoor air quality at individual workstations in office buildings. In this study, four ventilation systems were used in a test ...
Particle competition and cooperation for semi-supervised learning with label noise
(Elsevier B.V., 2015-07-21)
Semi-supervised learning methods are usually employed in the classification of data sets where only a small subset of the data items is labeled. In these scenarios, label noise is a crucial issue, since the noise may easily ...
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 ...
Exact Foldy-Wouthuysen transformation for real spin-0 particle in curved space
(2002-01-01)
Up to now, the only known exact Foldy-Wouthuysen transformation (FWT) in curved space is that concerning Dirac particles coupled to static spacetime metrics. Here we construct the exact FWT related to a real spin-0 particle ...
