Prediction of overall survival for patients with metastatic castration-resistant prostate cancer: development of a prognostic model through a crowdsourced challenge …

…, KT Tan, L Tomaziu, J Usset, YS Vang, R Vega… - The Lancet …, 2017 - thelancet.com
Background Improvements to prognostic models in metastatic castration-resistant prostate
cancer have the potential to augment clinical trial design and guide treatment strategies. In …

Retinal vessel extraction using lattice neural networks with dendritic processing

R Vega, G Sanchez-Ante, LE Falcon-Morales… - Computers in biology …, 2015 - Elsevier
Retinal images can be used to detect and follow up several important chronic diseases. The
classification of retinal images requires an experienced ophthalmologist. This has been a …

DA DICUS - Nuclear Physics, 1990 - academia.edu
The production of doubly charged Higgs scalars, H ũ+, via the W-fusion mechanism is
investigated. The possible standard model (SM) backgrounds to H+ ũ decay into like charge …

Constraints on CP violation in the Higgs sector from the ρ parameter

A Pomarol, R Vega - Nuclear Physics B, 1994 - Elsevier
We discuss the relation between CP symmetry and the custodial SU(2) symmetry in the Higgs
sector. In particular, we show that CP violation in the Higgs-gauge sector is allowed only if …

Effect of sucrose concentration on the composition of enzymatically synthesized short-chain fructo-oligosaccharides as determined by FTIR and multivariate analysis

N Romano, M Santos, P Mobili, R Vega… - Food Chemistry, 2016 - Elsevier
Fructo-oligosaccharides (FOS) are mixtures of oligosaccharides composed of fructose and
glucose units. As their composition is determined by the synthesis conditions, the goals of this …

[HTML][HTML] SIMLR: Machine Learning inside the SIR model for COVID-19 Forecasting

R Vega, L Flores, R Greiner - Forecasting, 2022 - mdpi.com
Accurate forecasts of the number of newly infected people during an epidemic are critical for
making effective timely decisions. This paper addresses this challenge using the SIMLR …

[HTML][HTML] Accurate long-range forecasting of COVID-19 mortality in the USA

…, A Mari Oriyad, MA Lewis, Z Maleki, R Vega… - Scientific reports, 2021 - nature.com
The need for improved models that can accurately predict COVID-19 dynamics is vital to
managing the pandemic and its consequences. We use machine learning techniques to design …

The effect of processing conditions on the stability of fructooligosaccharides in acidic food products

R Vega, ME Zuniga-Hansen - Food Chemistry, 2015 - Elsevier
The effect of processing conditions (temperature and degree of polymerisation, DP) on the
stability of short-chain fructooligosaccharides (sc-FOS) was investigated in three reaction …

A new mechanism and kinetic model for the enzymatic synthesis of short-chain fructooligosaccharides from sucrose

R Vega, ME Zuniga-Hansen - Biochemical Engineering Journal, 2014 - Elsevier
A kinetic model based on a ping-pong mechanism was developed under the steady-state
hypothesis to account for the short-chain fructooligosaccharides (sc-FOS) synthesis using the …

Resurgent Stokes data for Painlevé equations and two-dimensional quantum (super) gravity

S Baldino, R Schiappa, M Schwick, R Vega - arXiv preprint arXiv …, 2022 - arxiv.org
Resurgent-transseries solutions to Painleve equations may be recursively constructed out of
these nonlinear differential-equations -- but require Stokes data to be globally defined over …
