Path to fracture in granular flows: dynamics of contact networks.

Physical review. E, Statistical, nonlinear, and soft matter physics

Herrera M, McCarthy S, Slotterback S, Cephas E, Losert W, Girvan M.
PMID: 21797354
Phys Rev E Stat Nonlin Soft Matter Phys. 2011 Jun;83(6):061303. doi: 10.1103/PhysRevE.83.061303. Epub 2011 Jun 27.

Capturing the dynamics of granular flows at intermediate length scales can often be difficult. We propose studying the dynamics of contact networks as a new tool to study fracture at intermediate scales. Using experimental three-dimensional flow fields with particle-scale...

Involvement of the atrial natriuretic peptide in cardiovascular pathophysiology and its relationship with exercise.

International archives of medicine

de Almeida JC, Alves CL, de Abreu LC, Sato MA, Fonseca FL, de Mello Monteiro CB, Vanderlei LC, Macedo H, Tavares CM, Herrero D, Rodrigues LM, Valenti VE.
PMID: 22313592
Int Arch Med. 2012 Feb 07;5(1):4. doi: 10.1186/1755-7682-5-4.

In this minireview we describe the involvement of the atrial natriuretic peptide (ANP) in cardiovascular pathophysiology and exercise. The ANP has a broad homeostatic role and exerts complex effects on the cardio-circulatory hemodynamics, it is produced by the left...

Panniculitis caused by Mycobacterium monacense mimicking erythema induratum: a case in Ecuador.

New microbes and new infections

Romero JJ, Herrera P, Cartelle M, Barba P, Tello S, Zurita J.
PMID: 26933504
New Microbes New Infect. 2016 Jan 22;10:112-5. doi: 10.1016/j.nmni.2016.01.006. eCollection 2016 Mar.

We report the first case of recently characterized species M. monacense associated with chronic nodular vasculitis, infecting a young woman. This case represents the first isolation of M. monacense from Ecuador. The isolate was identified by conventional and molecular...

Multicore fiber-Bragg-grating-based directional curvature sensor interrogated by a broadband source with a sinusoidal spectrum.

Optics letters

Zheng D, Madrigal J, Chen H, Barrera D, Sales S.
PMID: 28914939
Opt Lett. 2017 Sep 15;42(18):3710-3713. doi: 10.1364/OL.42.003710.

A simple, spectral-drift-insensitive interrogation scheme for a multicore fiber Bragg grating (FBG)-based directional curvature sensor is proposed. The basic principle is to transform the wavelength shift of FBGs into the reflected power variation, which is accomplished by utilizing a...

Land surface temperature as an indicator of the unsaturated zone thickness: A remote sensing approach in the Atacama Desert.

The Science of the total environment

Urqueta H, Jódar J, Herrera C, Wilke HG, Medina A, Urrutia J, Custodio E, Rodríguez J.

Opt Express. 2017 Oct 02;25(20):24650-24657. doi: 10.1364/OE.25.024650.

This paper is focused on the characterization of a fiber Bragg grating (FBG) sensor interrogation system based on a fiber ring laser with a semiconductor optical amplifier as the gain medium, and an in-loop electro-optical modulator. This system operates...

Study on the impact of partition-induced dataset shift on k-fold cross-validation.

IEEE transactions on neural networks and learning systems

Moreno-Torres JG, Saez JA, Herrera F.
PMID: 24807526
IEEE Trans Neural Netw Learn Syst. 2012 Aug;23(8):1304-12. doi: 10.1109/TNNLS.2012.2199516.

Cross-validation is a very commonly employed technique used to evaluate classifier performance. However, it can potentially introduce dataset shift, a harmful factor that is often not taken into account and can result in inaccurate performance estimation. This paper analyzes...
