Negatively Charged Donors in Flat Quantum Dots
Self-assembled quantum dot Adiabatic approximation Binding energies
font style='font-size:12px;'>
2010/9/25
The ground state energies of off-axis negatively charged donors in axially symmetrical quantum dots, with different shapes but in all cases with a small height-to-base radius aspect ratio are calculat...
CO32− concentration and pCO2 thresholds for calcification and dissolution on the Molokai reef flat,Hawaii
CO32− concentration pCO2 thresholds calcification dissolution
font style='font-size:12px;'>
2010/1/13
The severity of the impact of elevated atmospheric pCO2 to coral reef ecosystems depends, in part, on how seawater pCO2 affects the balance between calcification and dissolution of carbonate sediments...
Spatial and temporal patterns of mineralization rates and oxygen distribution in a permeable intertidal sand flat (Sylt, Germany)
Spatial and temporal rates oxygen distribution

2014/5/5
Oxygen distribution and benthic mineralization rates were investigated in a permeable intertidal sand flat
(permeability: 3.9 3 10211 m2

Tidal dynamics of dissolved and particulate matter and bacteria in a tidal flat ecosystem in spring and fall
Tidal dynamics of dissolved particulate matter bacteria in a tidal flat ecosystem spring and fall
font style='font-size:12px;'>
2014/5/19
Tidal flat ecosystems are highly dynamic environments with tremendous short-term and long-term changes in physical, chemical, and biological properties. We measured salinity, temperature, oxygen, dry ...
Strings in Flat Space and Plane Waves from N = 4 Super Yang Mills
Strings Flat Space Plane Waves N = 4 Super Yang Mills
font style='font-size:12px;'>
2010/10/18
We explain how the string spectrum in flat space and plane waves arises from the large N limit of U(N) N = 4 super Yang Mills. We reproduce the spectrum by summing a subset of the planar Feynman diagr...
Scalar flat metrics of Eguchi-Hanson type
Scalar curvature Eguchi-Hanson metric generalized positive action conjecture
font style='font-size:12px;'>
2018/4/20
We use a new method to construct a class of asymptotically locally flat, scalar flat metrics. These metrics were constructed via algebraic geometry method by LeBrun before and provide counterexamples ...
On Marcinkiewicz Integrals along flat surfaces
Marcinkiewicz integral rough kernels flat curves Fourier transform area integral Littlewood-Paley gl* functions
font style='font-size:12px;'>
2010/2/26
In this paper, we study Marcinkiewicz integral operators with rough kernels supported by surfaces given by flat curves. Under convexity assumptions on our surfaces, we establish an Lp boundedness resu...

2014/4/3
One of the central difficulties in connection to the L^2 bounded curvature conjecture in general relativity is to be able to control the causal structure of spacetimes with this very limited regularit...

2010/4/13
We started the evolution of a flat universe from a nonsingular state called prematter which is governed by an inflationary equation of state P=(g -1)r , where g represents the initial vacuum dominance...

2010/3/1
In this paper, we study Marcinkiewicz integral operators with rough kernels supported by surfaces of revolutions. We prove that our operators are bounded on Lp under certain convexity assumptions on o...
