Validation of patient-specific 3D impression models for pelvic oncological orthopedic surgery

Autor: L, Mediavilla-Santos, M, García-Sevilla, J A, Calvo-Haro, M T, Ruiz Alba, R, Pérez-Mañanes, J, Pascau González, M, Cuervo Dehesa, F J, Vaquero Martín

Publikováno v: Revista espanola de cirugia ortopedica y traumatologia. 66(5)

Pelvic ring tumors pose a challenge due to the difficulty in obtaining adequate surgical margins. Tools such as surgical navigation or 3D printing for the fabrication of patient-specific surgical positioning templates help in preoperative planning an

Physics-Informed Gaussian Process Regression for Optical Fiber Communication Systems

Autor: Josh W. Nevin, F. J. Vaquero-Caballero, David J. Ives, Seb J. Savory

We present a framework for enhancing Gaussian process regression machine learning models with a priori knowledge derived from models of the transmission physics in optical networks. This is done by framing the regression problem as multi-task learnin

The knee prosthesis constraint dilemma: Biomechanical comparison between varus-valgus constrained implants and rotating hinge prosthesis. A cadaver study

Autor: Victor Estuardo León-Román, David García-Mato, F J Vaquero-Martín, Pablo Sanz-Ruiz, Irene Isabel Lopez-Torres, José Antonio Calvo-Haro, Javier Pascau

Publikováno v: Journal of orthopaedic research : official publication of the Orthopaedic Research SocietyREFERENCES. 39(7)

The real degree of constriction of rotating hinge knee (RHK) and condylar constrained prostheses (CCK) is a matter of discussion in revision knee arthroplasty. The objectives of this study are to compare the tibial rotation of both implants and valid

Autor: Michael Andrew Reimer, Charles Laperle, Robert J. Vincent, Maurice O'Sullivan, Andrew D. Shiner, D. Charlton, David J. Ives, F. J. Vaquero-Caballero, Seb J. Savory

Publikováno v: OFC

The impact of CPE the estimation linear and nonlinear noises is studied. Using previously reported second-order statistical metrics, CPE increases the maximum error from 0.16dB to 0.59dB whereas alternative metrics give 0.26dB independent of CPE.

Machine Learning Based Noise Estimation in Optical Fiber Communication Networks

Autor: Seb J. Savory, F. J. Vaquero Caballero

Publikováno v: 2018 IEEE Photonics Society Summer Topical Meeting Series (SUM).

In this paper, we discuss a machine learning based approach to jointly estimating both linear and nonlinear noise contributions in an optical fiber communication link. We will expound the rational for utilizing machine learning for this problem, befo
