Robust optical flow integration.

IEEE transactions on image processing : a publication of the IEEE Signal Processing Society

Crivelli T, Fradet M, Conze PH, Robert P, Pérez P.
PMID: 25020094
IEEE Trans Image Process. 2015 Jan;24(1):484-98. doi: 10.1109/TIP.2014.2336547. Epub 2014 Jul 08.

We analyze the problem of how to correctly construct dense point trajectories from optical flow fields. First, we show that simple Euler integration is unavoidably inaccurate, no matter how good is the optical flow estimator. Then, an inverse integration...

A FPGA embedded web server for remote monitoring and control of smart sensors networks.

Atomic-Scale Sliding Friction on Graphene in Water.

ACS nano

Vilhena JG, Pimentel C, Pedraz P, Luo F, Serena PA, Pina CM, Gnecco E, Pérez R.
PMID: 26982997
ACS Nano. 2016 Apr 26;10(4):4288-93. doi: 10.1021/acsnano.5b07825. Epub 2016 Mar 23.

The sliding of a sharp nanotip on graphene completely immersed in water is investigated by molecular dynamics (MD) and atomic force microscopy. MD simulations predict that the atomic-scale stick-slip is almost identical to that found in ultrahigh vacuum. Furthermore,...

Surfactant chain length and concentration influence on the interfacial tension of two immiscible model liquids: a coarse-grained approach.

Journal of molecular modeling

Catarino Centeno R, Bustamante-Rendón RA, Hernández-Fragoso JS, Arroyo-Ordoñez I, Pérez E, Alas SJ, Gama Goicochea A.
PMID: 28986687
J Mol Model. 2017 Oct 06;23(11):306. doi: 10.1007/s00894-017-3474-x.

The interfacial tension between immiscible liquids is studied as a function of a model linear surfactant length and concentration using coarse-grained, dissipative particle dynamics numerical simulations. The adsorption isotherms obtained from the simulations are found to be in agreement...

Oospore dimensions and morphology in North American Tolypella (Charophyceae, Charophyta).

Journal of phycology

Pérez W, Hall JD, McCourt RM, Karol KG.
PMID: 26986526
J Phycol. 2015 Apr;51(2):310-20. doi: 10.1111/jpy.12275. Epub 2015 Feb 11.

Characteristics of the oospores have been used to delimit sections and, in some cases, species in the genus Tolypella A. Braun. To test the utility of oospore characters for identifying North American species of Tolypella, we investigated oospores from...

An Algorithm Using Administrative Data to Identify Patient Attachment to a Family Physician.

International journal of family medicine

Provost S, Pérez J, Pineault R, Borgès Da Silva R, Tousignant P.
PMID: 26413320
Int J Family Med. 2015;2015:967230. doi: 10.1155/2015/967230. Epub 2015 Aug 27.

Background. Commonly self-reported questions in population health surveys, such as "do you have a family physician?", represent one of the best-known sources of information about patients' attachment to family physicians. Is it possible to find a proxy for this...

Characteristics of a Canine Distemper Virus Outbreak in Dichato, Chile Following the February 2010 Earthquake.

Animals : an open access journal from MDPI

Garde E, Pérez G, Acosta-Jamett G, Bronsvoort BM.
PMID: 26479537
Animals (Basel). 2013 Aug 27;3(3):843-54. doi: 10.3390/ani3030843.

Following the earthquake and tsunami disaster in Chile in February 2010, residents of Dichato reported high morbidity and mortality in dogs, descriptions of which resembled canine distemper virus (CDV). To assess the situation, free vaccine clinics were offered in...

Challenges Encountered During the Veterinary Disaster Response: An Example from Chile.

Animals : an open access journal from MDPI

Garde E, Pérez GE, Acosta-Jamett G, Bronsvoort BM.
PMID: 26479753
Animals (Basel). 2013 Nov 21;3(4):1073-85. doi: 10.3390/ani3041073.

Large-scale disasters have immeasurable effects on human and animal communities. Evaluating and reporting on the response successes and difficulties encountered serves to improve existing preparedness documents and provide support to those in the process of developing plans. Although the...

Phosphocholine-Specific Antibodies Improve T-Dependent Antibody Responses against OVA Encapsulated into Phosphatidylcholine-Containing Liposomes.

Frontiers in immunology

Cruz-Leal Y, López-Requena A, Lopetegui-González I, Machado Y, Alvarez C, Pérez R, Lanio ME.
PMID: 27713745
Front Immunol. 2016 Sep 22;7:374. doi: 10.3389/fimmu.2016.00374. eCollection 2016.

Liposomes containing phosphatidylcholine have been widely used as adjuvants. Recently, we demonstrated that B-1 cells produce dipalmitoyl-phosphatidylcholine (DPPC)-specific IgM upon immunization of BALB/c mice with DPPC-liposomes encapsulating ovalbumin (OVA). Although this preparation enhanced the OVA-specific humoral response, the contribution...
