Structural Measurement Errors in Nonseparable Models [PDF]

open access: yes, 2009
This paper considers measurement error from a new perspective. In surveys, response errors are often caused by the fact that respondents recall past events and quantities imperfectly.

Comparative Protein Structure Modeling Using MODELLER [PDF]

open access: yesCurrent Protocols in Protein Science, 2006
AbstractFunctional characterization of a protein sequence is a common goal in biology, and is usually facilitated by having an accurate three‐dimensional (3‐D) structure of the studied protein. In the absence of an experimentally determined structure, comparative or homology modeling can sometimes provide a useful 3‐D model for a protein that is ...

Structural Model of Eumelanin [PDF]

open access: yesPhysical Review Letters, 2006
Melanin is a ubiquitous pigment in living organisms with multiple important functions, yet its structure is not well understood. We propose a structural model for eumelanin protomolecules, consisting of 4 or 5 of the basic molecular units (hydroquinone, indolequinone, and its tautomers), in arrangements that contain an inner porphyrin ring. We use time-

Protein Structure Modeling with MODELLER

open access: yes, 2014
Genome sequencing projects have resulted in a rapid increase in the number of known protein sequences. In contrast, only about one-hundredth of these sequences have been characterized at atomic resolution using experimental structure determination methods.

Pedestal Structure Model

open access: yesPhysical Review Letters, 2012
Predictions are developed for gradients and profiles of the electron density and temperature in tokamak H-mode pedestals that are in transport quasiequilibrium. They are based on assuming paleoclassical processes provide the irreducible minimum radial plasma transport and dominate in the steep gradient regions of pedestals.
