Plasma volume expansion is an important component of a successful pregnancy. The failure of maternal plasma volume expansion has been implicated in adverse obstetric outcomes such as pre-eclampsia, fe...
USING INDIVIDUAL TREE CROWN APPROACH FOR FOREST VOLUME EXTRACTION WITH AERIAL IMAGES AND LASER POINT CLOUDS
Individual Tree Crown (ITC) Laser scanning Tree height Aerial imagery Segmentation

2015/8/13
The objective of this paper is to improve the cost-effectiveness (accuracy of estimates versus applied costs) of present ITC
(Individual Tree Crown) approaches which are based on 1) aerial imagery or...

Abstract: In this paper, we show that the derivative of the genus-1 Virasoro conjecture for Gromov-Witten invariants along the direction of quantum volume element holds for all smooth projective varie...
Financial factor influence on scaling and memory of trading volume in stock market
Financial facto trading volume stock market

2011/9/13
We study the daily trading volume volatility of 17,197 stocks in the U.S. stock markets during the period 1989–2008 and analyze the time return intervals between volume volatilities above a given th...
Curvature of the QCD phase transition line in a finite volume
the QCD phase transition line finite volume

The curvature which characterizes the QCD phase transition at finite temperature and small values of the chemical potential is accessible to lattice simulations. The results for this quantity which ha...
Hadron electric polarizability -- finite volume corrections
Hadron electric polarizability finite volume corrections
font style='font-size:12px;'>
2011/1/7
We use the background field method to extract the polarizability for the neutral "pion". In our previous study we found that the polarizability for this system is negative which is believed to be a fi...

2010/12/23
The low energy effective theory on a stack of D3-branes at a Calabi-Yau singularity is an $\mathcal{N} = 1$ quiver gauge theory. The AdS/CFT correspondence predicts that the strong coupling dynamics ...

2010/12/23
We examine the large volume compactification of Type IIB string theory or its F theory limit and the associated supersymmetry breakdown and soft terms. It is crucial to incorporate the loop-induced m...
Generalized Geometry in AdS/CFT and Volume Minimization
Generalized Geometry AdS/CFT Volume Minimization
font style='font-size:12px;'>
2010/12/24
We study the general structure of the AdS_5/CFT_4 correspondence in type IIB string theory from the perspective of generalized geometry. We begin by defining a notion of "generalized Sasakian geometr...
Volume-Enclosing Surface Extraction

A new method is presented here, which allows for the construction of triangular surfaces from
three-dimensional data sets, such as 3D image data and/or numerical simulation data that are
based on re...
