What Population Reveals about Individual Cell Identity: Single-Cell Parameter Estimation of Models of Gene Expression in Yeast 

Llamosi, Artémis; González-Vargas, Andrés M.; Versari, Cristian; Cinquemani, Eugenio; Ferrari-Trecate, Giancarlo; Hersen, Pascal; Batt, Grégory (Public Library of Science, 2016-02-09)
Significant cell-to-cell heterogeneity is ubiquitously observed in isogenic cell populations. Consequently, parameters of models of intracellular processes, usually fitted to population-averaged data, should rather be ...

Cross-ratio identities and higher-order poles of CHY-integrand 

Cardona, Carlos A.; Feng, Bo; Gomez, Humberto; Huang, Rijun (Springer Verlag, 2016-09-01)
The evaluation of generic Cachazo-He-Yuan(CHY)-integrands is a big challenge and efficient computational methods are in demand for practical evaluation. In this paper, we propose a systematic decomposition algorithm by ...

Computation of contour integrals on ℳ0,n 

Cachazo, Freddy; Gomez, Humberto (Springer Verlag, 2016-04-01)
Contour integrals of rational functions over (Formula presented.) , the moduli space of n-punctured spheres, have recently appeared at the core of the tree-level S-matrix of massless particles in arbitrary dimensions. The ...

Elliptic scattering equations 

Cardona, Carlos A.; Gomez, Humberto (Springer Verlag, 2016-06-01)
Recently the CHY approach has been extended to one loop level using elliptic functions and modular forms over a Jacobian variety. Due to the difficulty in manipulating these kind of functions, we propose an alternative ...

Λ scattering equations 

Gomez, Humberto (Springer Verlag, 2016-06-01)
Abstract: The CHY representation of scattering amplitudes is based on integrals over the moduli space of a punctured sphere. We replace the punctured sphere by a double-cover version. The resulting scattering equations ...

Effect of modification substrate on the microstructure of hydroxyapatite coating 

Realpe-Jaramillo, J.; Morales-Morales, Jimmy Alexander; González-Sánchez, J.; Cabanzo, Rafael; Mejía-Ospino, Enrique; Rodríguez-Pereira, Jhonatan (Institute of Physics Publishing, 2017-01-25)
Bioactive hydroxyapatite (HA) coatings were fabricated by a precipitation, sol-gel and dip-coating method. The effects of the aging time and the base used to adjust pH and substrate materials on the phases and microstructures ...

Reliability and dimensionality of PHQ-9 in screening depression symptoms among health science students in Cartagena, 2014 

Unknown author (Instituto Nacional de Salud, 2017-04-01)
Introduction: Depression among university students must be screened with valid instruments. The Patient Health Questionnaire (PHQ-9) is reliable and valid for screening depression in a university context; however, its ...

Effect of substrate nature on the electrochemical deposition of calcium-deficient hydroxyapatites 

Gualdrón-Reyes, A. F.; Domínguez-Vélez, V.; Morales-Morales, Jimmy Alexander; Cabanzo, Rafael; Meléndez, A. M. (Institute of Physics Publishing, 2017-01-25)
Calcium phosphates were obtained by reducing nitrate ions to produce hydroxide ions on TiO2/stainless steel and TiO2/titanium electrodes. TiO2 coatings on metallic substrates were prepared by sol-gel dip-coating method. ...

1020 steel coated with Ti/TiN by Cathodic Arc and Ion Implantation 

Bermeo, F.; Quintana, Juan Pablo; Kleiman, Ariel; Sequeda, Federico O.; Márquez, Adrianna Beatriz (Institute of Physics Publishing, 2017-03-08)
TiN coatings have been widely studied in order to improve mechanical properties of steels. In this work, thin Ti/TiN films were prepared by plasma based immersion ion implantation and deposition (PBII&D) with a cathodic ...
