Models of stress at mid-ocean ridges and their offsets [PDF]

open access: yes, 2000
This thesis aims to investigate the stresses at mid-ocean ridge offsets, and particularly at the particular class of offsets represented by oceanic microplates. Amongthese, the Easter microplate is one of the best surveyed.

Endeavour Segment of the Juan de Fuca Ridge: One of the Most Remarkable Places on Earth [PDF]

open access: yesOceanography, 2012
Endeavour Segment of the Juan de Fuca Ridge is one of three Integrated Study Sites for the Ridge 2000 Program. It is a remarkable, dynamic environment hosting five major hydrothermal fields, numerous smaller fields, and myriad diffuse-flow sites; magma ...

Cerro prieto and its relation to the gulf of California spreading centers

open access: yesCiencias Marinas, 1996
The Cerro Prieto geothermal field is located in the Mexicali Valley, Baja California. Tectonically, this northern part of the Gulf of California has been classified as a spreading center, within a transitional area of oceanic to continental conditions ...

Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

open access: yesFEBS Letters, EarlyView.
Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

Lava Geochemistry as a Probe into Crustal Formation at the East Pacific Rise [PDF]

open access: yesOceanography, 2012
Basalt lavas comprise the greatest volume of volcanic rocks on Earth, and most of them erupt along the world's mid-ocean ridges (MORs). These MOR basalts (MORBs) are generally thought to be relatively homogeneous in composition over large segments of the

L‐aspartate oxidase provides new insights into fumarate reduction in anaerobic darkness in Synechocystis sp. PCC6803

open access: yesFEBS Letters, EarlyView.
Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

Determiner spreading

open access: yes
Determiner spreading (or polydefiniteness or article doubling) is the phenomenon whereby the definite article appears before both the head noun and adjectival modifiers in definite noun phrases.

Layered Steered Space–Time-Spreading-Aided Generalized MC DS-CDMA

open access: yes, 2010
—We present a novel trifunctional multiple-input– multiple-output (MIMO) scheme that intrinsically amalgamates space–time spreading (STS) to achieve a diversity gain and a Vertical Bell Labs layered space–time (V-BLAST) scheme to attain a multiplexing ...

Active Long-Lived Faults Emerging Along Slow-Spreading Mid-Ocean Ridges [PDF]

open access: yesOceanography, 2012
In the classic mid-ocean ridge model, new seafloor is generated through a combination of magmatic diking feeding lava flows at the spreading axis, and the formation of short-offset, high-angle normal faults that dip toward the axis.

Artificial molecular machines and motors—Design and control of nanoscale motion

open access: yesFEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...
