SELFE: A semi-implicit Eulerian–Lagrangian finite-element model for cross-scale ocean circulation

Y Zhang, AM Baptista - Ocean modelling, 2008 - Elsevier
Unstructured-grid models grounded on semi-implicit, finite-volume, Eulerian–Lagrangian
algorithms, such as UnTRIM and ELCIRC, have enjoyed considerable success recently in …

Economic implications of using a mean-VaR model for portfolio selection: A comparison with mean-variance analysis

GJ Alexander, AM Baptista - Journal of Economic Dynamics and Control, 2002 - Elsevier
We relate value at risk (VaR) to mean-variance analysis and examine the economic
implications of using a mean-VaR model for portfolio selection. When comparing two mean-variance …

A comparison of VaR and CVaR constraints on portfolio selection with the mean-variance model

GJ Alexander, AM Baptista - Management science, 2004 - pubsonline.informs.org
In this paper, we analyze the portfolio selection implications arising from imposing a value-at-risk
(VaR) constraint on the mean-variance model, and compare them with those arising …

Salmon at river's end: the role of the estuary in the decline and recovery of Columbia River salmon

DL Bottom, CA Simenstad, J Burke, AM Baptista… - 2005 - pdxscholar.library.pdx.edu
The continued decline of Columbia River salmon (Oncorhynchus spp.) populations has long
focused concerns on habitat changes upriver, particularly the effects of large hydroelectric …

Constant-pH molecular dynamics using stochastic titration

AM Baptista, VH Teixeira, CM Soares - The Journal of chemical …, 2002 - pubs.aip.org
A new method is proposed for performing constant-pH molecular dynamics (MD) simulations,
that is, MD simulations where pH is one of the external thermodynamic parameters, like the …

A cross-scale model for 3D baroclinic circulation in estuary–plume–shelf systems: I. Formulation and skill assessment

Y Zhang, AM Baptista, EP Myers - Continental Shelf Research, 2004 - Elsevier
Challenges posed by the Columbia River estuary–plume–shelf system have led to the
development of ELCIRC, a model designed for the effective simulation of 3D baroclinic circulation …

Spatial variability overwhelms seasonal patterns in bacterioplankton communities across a river to ocean gradient

CS Fortunato, L Herfort, P Zuber, AM Baptista… - The ISME …, 2012 - academic.oup.com
Few studies of microbial biogeography address variability across both multiple habitats and
multiple seasons. Here we examine the spatial and temporal variability of bacterioplankton …

Relationship between cutting force and PCD cutting tool wear in machining silicon carbide reinforced aluminium

JP Davim, AM Baptista - Journal of materials processing technology, 2000 - Elsevier
This paper presents a study of the relationship between cutting forces and tool wear of
polycrystalline diamond (PCD), measured when machining the composite A356/20/SiCp-T6 (…

Simulation of protein conformational freedom as a function of pH: constant‐pH molecular dynamics using implicit titration

AM Baptista, PJ Martel… - … : Structure, Function, and …, 1997 - Wiley Online Library
Solution pH is a determinant parameter on protein function and stability, and its inclusion in
molecular dynamics simulations is attractive for studies at the molecular level. Current …
