We describe here the synthesis and characterization of the solution conformation of a molecule which brings into close proximity the principal molecular components believed to participate in the initi...
A Structural Model of Electoral Accountability
discipline selection political agency elections structural estimation maximum likelihood
2015/9/18
This paper proposes a structural approach to measuring the e§ects of electoral accountability. We estimate a political agency model with imperfect information in orderto identify and quantify discipli...
Acid-base properties and structons: towards a structural model for predicting the thermodynamic properties of silicate melts
silicate melt acid-base oxide melt thermodynamic properties
2015/9/10
Phase equilibrium relationships in igneous systems can be estimated using empirical mathematical models based on
multi-component regular solution formulae. Although these provide useable results with...
ALGORITHMS FOR A STRUCTURAL MODEL OF BIPED LOCOMOTION IN THE CONFIGURATION SPACE
Model-based processing Navigation
2015/1/6
Mechanical models for locomotion are strongly hierarchised depending on the gait phase, tasks to be performed and constraints. There is an alternance between different constraints involving to differe...
The Effects of Cooperation: A Structural Model of Siblings' Caregiving Interactions
time allocation (non)cooperation structural modelling
2012/10/30
This paper analyzes the decision making process of adult children to provide informal care to their parents. First, we develop a structural model to explain the amount of time that only children (with...
New structural model for GeO2/Ge interface: A first-principles study
New structural model for GeO2/Ge interface first-principles study
2010/11/24
First-principles modeling of a GeO2/Ge(001) interface reveals that sixfold GeO2, which is derived from cristobalite and is different from rutile, dramatically reduces the lattice mismatch at the inter...
Companies' decisions for profit maximization: A structural model
Equilibrium model Technology renewal
2010/9/14
Huge analyses on firms data selected from public available databases accomplished the task to describe the size and growth of firms through interpolating functions. The structure and internal firms or...
不同种植密度番茄生长行为的结构功能模型模拟（Simulation of Tomato Growth Behavior in Response to Planting-density Based on Functional-structural Model）
温室 番茄 种植密度 GreenLab模型
2009/11/3
为研究不同密度下温室番茄的生长行为，对结构功能模型GreenLab进行改进，在提高拟合度的基础上，获得不同密度下番茄生长参数，通过参数分析将环境与番茄植株生长行为相联系。结果表明密度影响同化物产生与分配，通过外在形态，如出叶速率、叶厚、坐果率等表现，GreenLab模型可以重建这种生长行为变化。
A structural model on a hypercube represented by optimal transport
determinant maximization Fourier series graphical model lasso optimal transport structural gradient model
2010/3/17
We propose a flexible statistical model for high-dimensional quantitative
data on a hypercube. Our model, called the structural gradient model (SGM),
is based on a one-to-one map on the hypercube th...
