Increased cellular brevetoxins in the red tide dinoflagellate Karenia brevis under CO2 limitation of growth rate: Evolutionary implications and potential effects on bloom toxicity
Increased cellular brevetoxins Karenia brevis
font style='font-size:12px;'>
2014/4/2
Karenia brevis blooms impair human health, marine ecosystems, and coastal economies in the Gulf of Mexico
via their production of carbon-based neurotoxins (brevetoxins), which contain no nitrogen (N)...
Growth rate of continental crust in the northeast margin of the North China Craton: Constraints from the U–Pb dating and Lu–Hf isotopes of detrital zircons from the Laoha River
North China Craton detrital zircon U–Pb age Hf isotope Laoha River

2017/4/11
Recently, how to quantitatively estimate the growth rate of continental crust is an enigmatic issue. With the development
of ICP-MS technology, the U–Pb dating and Lu–Hf isotopic compositions of detr...
Coral growth-rate insensitive Sr/Ca as a robust temperature recorder at the extreme latitudinal limits of Porites
skeletal oxygen isotope in the coral Sr/Ca high latitudes coral growth rates
font style='font-size:12px;'>
2017/4/11
Oxygen isotope values of low-growth coral (<5 mm/yr) skeletons may reflect kinetic effects, which is problematic for
sea surface temperature (SST) reconstruction. Here, we report a Sr/Ca-based SST re...
The WiggleZ Dark Energy Survey: constraining the evolution of Newton's constant using the growth rate of structure
constraining evolution constant using growth rate structure
font style='font-size:12px;'>
2011/10/11
We constrain the evolution of Newton's constant using the growth rate of large-scale structure measured by the WiggleZ Dark Energy Survey in the redshift range $0.1 < z < 0.9$. We use this data in two...

We will show that the cotangent bundle of an integrally hyperbolic manifold is not symplectomorphic to any smooth affine variety. We will also show that the unit cotangent bundle of such a manifold is...
High growth rate 4H-SiC epitaxial growth using dichlorosilane in a hot-wall CVD reactor
High growth rate 4H-SiC epitaxial growth hot-wall CVD reactor

2010/11/18
Thick, high quality 4H-SiC epilayers have been grown in a vertical hot-wall chemical
vapor deposition system at a high growth rate on (0001) 80 off-axis substrates. We
discuss the use of dichlorosil...
