15. Metabolomics applied to maternal and perinatal health: a review of new frontiers with a translation potential
The prediction or early diagnosis of maternal complications is challenging mostly because the main conditions, such as preeclampsia, preterm birth, fetal growth restriction, and gestational diabetes mellitus, are complex syndromes with multiple underlying mechanisms related to their occurrence. Limited advances in maternal and perinatal health in recent deca

17. Statistics of the Pareto front in Multi-objective Optimization under Uncertainties
Abstract In this paper we address an innovative approach to determine the mean and a confidence interval for a set of objects analogous to curves and surfaces. The approach is based on the determination of the most representative member of the family by minimizing a Hausdorff distance. This method is applied to the analysis of uncertain Pareto frontiers in m

20. Globally and locally applied naturalistic metaphysics
ABSTRACT This article addresses the prospects of applied naturalistic metaphysics from both a global and a local perspective. Adopting a broad Sellarsian approach, I look into whether metaphysics has a place and role in the overall scientific image and assess whether it has its own subject matter as a first- or second- order discipline. After outlining the g

22. Transcolonic Perirectal NOTES Access (PNA): A feasibility study with survival in swine model
ABSTRACT Transrectal access still has some unsolved issues such as spatial orientation, infection, access and site closure. This study presents a simple technique to perform transcolonic access with survival in a swine model series. A new technique for NOTES perirectal access to perform retroperitoneoscopy, peritoneoscopy, liver and lymphnode biopsies was pe

23. Link Optimization and Performance Analysis of a 40 Gbps DQPSK Modulated Ultra DWDM System with 32 Orthogonally Polarized channels
Abstract The demand for higher speed at a lesser transmission cost per bit resulted in growth of optical networks with improved spectral efficiency even at narrower channel spacing. Incorporation of multilevel modulation formats in DWDM system led to the exploration of the 25 GHz channel grid, popularly known as Ultra Dense Wavelength Division Multiplexed (U
