Origins of the Sensitivity of Molecular Vibrations to Electric Fields:Carbonyl and Nitrosyl Stretches in Model Compounds and Proteins
phosphoenolpyruvate carboxylase thermostable limited proteolysis flexible loop main chain connectivity
2016/5/24
The vibrational Stark effect (VSE) is the effect of an electric field on the vibrational spectrum. Typically, the largest change induced by an electric field is the linear frequency shift whose sensit...
Vibrational Stark Effects of Nitriles II. Physical Origins of Stark Effects from Experiment and Perturbation Models
platinum titania catalyst flame synthesis one-step oxidation screening
2016/5/23
Vibrational Stark effects, which are the effects of electric fields on vibrational spectra, were measured previously for the C−N stretch mode of several small nitriles, yielding difference dipol...
Origins of diverse feeding ecologies within Conus, a genus of venomous marine gastropods
Gastropoda Conus molecular phylogeny
2015/12/17
Specialized predators on polychaetes, fishes, hemichordates or other molluscs, members of the predominantly
tropical gastropod genus Conus diversified rapidly during the Miocene to consti...
The Hawaiian Islands are renowned for some
of the most spectacular species radiations in the world. Most of
these radiations have been attributed to single colonization
events, although the evidenc...
COMPARATIVE PHYLOGEOGRAPHY OF THREE CODISTRIBUTED STOMATOPODS: ORIGINS AND TIMING OF REGIONAL LINEAGE DIVERSIFICATION IN THE CORAL TRIANGLE
Allopatric speciation biodiversity center of origin
2015/12/17
The Indonesian-Australian Archipelago is the center of the world's marine biodiversity. Although many
biogeographers have suggested that this region is a "center of origin," criticism of this theory...
From atoms to steps:The microscopic origins of crystal evolution
Burton–Cabrera–Frank theory Solid-on-solid model Non-equilibrium statistical mechanics
2015/10/16
The Burton–Cabrera–Frank (BCF) theory of crystal growth has been successful in describing a wide range of phenomena in surface physics. Typical crystal surfaces are slightly misoriented with respect t...

May 15, 2003 marked the fiftieth anniversary of a paper published in the journal I that revolutionized our thinking about one of the fundamental scientific questions that confronts humanity-how did li...
The Moving Boundaries of Sea Level Change:Understanding the Origins of Geographic Variability
Sea Level Change Geographic Variability
2015/7/9
As ice sheets gain or lose mass, and as water moves between the continents and the ocean, the solid Earth deforms and the gravitational field of the planet is perturbed. Both of these effects lead to ...

The morphological diversities among star-forming galaxies at high redshifts in the great observatories origins deep survey
high-redshift fundamental parameters
2014/12/24
We used the deep, multiwavelength images obtained by the Great Observatories Origins Deep Survey (GOODS) to identify ~4700 Lyman break galaxies (LBGs) at z > 2.5, and 292 starburst galaxies at z ~ 1.2...
Disentangling the origins of branched tetraether lipids and crenarchaeol in the lower Amazon River: Implications for GDGT-based proxies

To trace the origin of branched glycerol dialkyl glycerol tetraethers (brGDGTs), their distribution in soils and suspended particulate matter (SPM) of Amazonian rivers and floodplain lakes (va′ rzeas)...
Disordered quantum wires: microscopic origins of the DMPK theory and Ohm's law
Disordered quantum wires microscopic origins the DMPK theory Ohm's law Mathematical Physics
2012/4/23
We study the electronic transport properties of the Anderson model on a strip, modeling a quasi one-dimensional disordered quantum wire. In the literature, the standard description of such wires is vi...

harmful algal bloom regional ocean modeling system, particle tracking Gulf of Mexico algal bloom
2014/4/1
The dinoflagellate Karenia brevis is the major harmful algal bloom (HAB) species in the Gulf of Mexico.
Given that the rapid appearance of K. brevis cannot be explained by plankton growth alone...
