• #### Structural determinants of functional behavior in distal pocket mutants of myoglobin ﻿

(1995)
The physiological role of myoglobin depends on the modulation of heme activity by the protein. The hypothesis that functional properties are governed by conserved residues in the distal pocket has been tested by site-directed ...
• #### Structural development and kinematic history of ramp-footwall collapse in the Doonerak multiduplex, central Brooks Range, arctic Alaska ﻿

(1992)
The Doonerak multiduplex of the central Brooks Range fold and thrust belt in arctic Alaska developed during footwall collapse beneath the Amawk thrust, which underlies the Endicott Mountains allochthon. The Endicott Mountains ...

(1979)
• #### STRUCTURAL DYNAMICS OF PHOTOLYZED MYOGLOBIN AT LOW TEMPERATURES BY X-RAY ABSORPTION FINE STRUCTURES ﻿

(1987)
X-ray absorption fine structures of photolyzed carboxymyoglobin were measured at 4 K and at 40 K. The latter was a 10-s-resolved measurement following photolysis. The goal of the project was to elucidate the dynamic pathways ...
• #### Structural evolution of metamorphic tectonites beneath the Silver Peak-Lone Mountain detachment fault, west-central Nevada ﻿

(1995)
The Silver Peak Range of west-central Nevada reveals metamorphic tectonites below a low-angle fault deformed in a northwesterly-trending doubly-plunging anticline. The rock units in the region are divided into a lower ...
• #### Structural evolution of SE Mexico (Chiapas-Tabasco-Campeche) offshore and onshore ﻿

(1995)
The Yucatan Platform bisects the NW-SE Sierra de Chiapas fold belt of SE Mexico at right angles. The outcropping Sierra de Chiapas involves Mesozoic platform carbonates, but its northwestern subsurface continuation involves ...
• #### Structural evolution of the central External Betic Cordillera, southern Spain ﻿

(1990)
A new tectonic subdivision of the central External Betic Cordillera is proposed based on previous stratigraphic studies, interpretation of seismic reflection profiles and balanced cross-sections. All available surface and ...
• #### Structural evolution of the Neogene Adana and Iskenderun basins, South Turkey ﻿

(1994)
The structural styles of the Neogene basins in Southern Turkey formed in two stages. (1) Early to Middle Miocene transtension in a NNW-SSE direction disrupting the Paleozoic--Mesozoic substratum in the Adana Basin and the ...
• #### Structural evolution of the offshore forearc basins of Peru, including the Salaverry, Trujillo, Lima, West Pisco and East Pisco basins ﻿

(1994)
The basins of the study area were filled with the following sequences: E$\sb0$ (lower? to middle Eocene); E1 E2 and E3 (fill middle Eocene half grabens); E-O (uppermost middle Eocene-Oligocene); M1, M2 and M3 (lower-upper ...
• #### Structural evolution of the Sergipe-Alagoas Basin, Brazil ﻿

(1989)
The evolution of the Sergipe-Alagoas Basin started during the Early Cretaceous, as part of the rift system that initiated the separation between the South American and African plates. The direction of propagation of the ...

(1977)

(1986)
• #### STRUCTURAL GEOLOGY, STRATIGRAPHY AND PETROLOGY OF THE ELKHORN RIDGE ARGILLITE, IN THE SUMPTER AREA, NORTHEASTERN OREGON ﻿

(1983)
The Elkhorn Ridge Argillite exposed in the Bourne-Sumpter area of eastern Oregon is a broken formation of metamorphosed (greenschist facies) hemipelagic sediments, reefal carbonates, rare clastics, mafic volcanics and ...
• #### Structural Health Monitoring System for Deepwater Risers with Vortex-Induced Vibration: Nonlinear Modeling, Blind Identification, Fatigue/Damage Estimation and Vibration Control ﻿

(2013-09-16)
This study focuses on developing structural health monitoring techniques to detect damage in deepwater risers subjected to vortex-induced vibration (VIV), and studying vibration control strategies to extend the service ...
• #### Structural heuristics for query optimization ﻿

(2004)
The join operation, which combines tuples from multiple relations, is the most fundamental and, typically, the most expensive operation in database queries. The standard approach to join-query optimization is cost based, ...
• #### Structural pattern matching for functional annotation of proteins ﻿

(2003)
Characterizing the function of every protein is one of the most important goals of genomics. However, the expense of experimentation makes the functional "annotation" of every protein simply infeasible. Thus, techniques ...
• #### Structural Sorting and Oxygen Doping of Semiconducting Single-Walled Carbon Nanotubes ﻿

(2012)
Existing growth methods produce single-walled carbon nanotubes (SWCNTs) with a range of structures and electronic properties, but many potential applications require pure nanotube samples. Density gradient ultracentrifugation ...
• #### Structural studies of membrane lytic peptides: A comparison of magainin and melittin ﻿

(1996)
Magainin and melittin are 2 members of a class of small amphipathic helical peptides which act as potent antibiotics or toxins. It has been shown that the peptides in this class interact directly with the lipid bilayer ...
• #### Structural topology and shape optimization using the finite element method ﻿

(2000)
The goal of structural optimization is to find the best possible configuration for a given structure, which meets the objective function and set of constraints. In this work we presented a method based on the evolutionary ...
• #### Structural Vibration Control of Nonlinear Systems Using the Smart Tuned Mass Damper (STMD) and the Nonlinear Tuned Mass Damper (NTMD) in Parallel ﻿

(2013-12-05)
Structural vibration control systems can be divided into four categories: 1) active control; 2) passive control; 3) semi-active control; and 4) hybrid control. It is well established that the semi-active control can provide ...
