3 - Discriminating Parkinson’s Disease (pd) Using Functional

Connectivity And Brain Network Analysis

Shouyi Wang, University of Texas at Arlington,

shouyiw@uta.edu

In this study, we explored the use of functional connectivity patterns in fMRI data

to classify subjects on the basis of Parkinson’s disease. We explore various brain

networks and features. We partition our fMRI data in 5 filtered frequency ranges.

We use a proximal support vector machine paired with a minimum-redundancy

and maximum-relevance feature selection method on each frequency range. We

use a majority voting ensemble classification method on the results of the

proximal support vector machine classification results. Our results indicate that

the ensemble method is effective compared to a single broad frequency range,

and that Bonferroni correction may enhance classification results.

1- Optimizing Breast Cancer Diagnostic Decisions to

Reduce Overdiagnosis

Although the early diagnosis of breast cancer through screening mammography

saves thousands of lives every year, overdiagnosis of breast cancer may cause

harm without benefit. We propose a comprehensive large-scale optimization

model to address overdiagnosis by making better-informed diagnostic decisions

and provide the exact optimal policies that potentially save up to 9% of the

biopsied population from overdiagnosis..

2 - A Decision Support System for the Management of Aid-In-Kind

Turkish Red Crescent is the main body for collection and distribution of donations

in Turkey, and this project aims to improve their donation collection and

distribution processes by proposing a decision support system with numerous

subsystems; e.g. implementing new process flows and their accompanying

decisions. The proposed system is approved by TRC and it is being integrated to

their systems.

Climate Change

We develop a two-stage stochastic model to optimally place green roofs and/or

Photovoltaic panels under climate change uncertainty, with the aim of improving

urban system resilience. Different climate forecasts from different climate models

are taken into account as different scenarios. The interaction between green roofs

and Photovoltaic panels in terms of efficiency is considered. An efficient L-shaped

algorithm is developed. Computational studies along with sensitivity analysis are

conducted.

Precipitation Uncertainty

Green Infrastructures (GIs) are low cost, low regret strategies that can

dramatically contribute to stormwater management. We develop a multi-objective

stochastic programming model to determine the optimal placement of GIs across a

set of candidate locations in a watershed to minimize the excess runoff under

short-term and medium-term precipitation uncertainties. We calibrate the model

using precipitation projections and stormwater system’s hydrologic responses to

them. We obtain the optimal GI placement for a watershed and perform

sensitivity and robustness analyses to provide insights.

Despite the environmental and societal benefits of Green Infrastructure (GI), they

are mostly planned and established in response to an existing problem rather than

being actively incorporated into the early stages of urban planning. In this paper,

we present a stochastic model that would allow urban planners to incorporate

uncertainties in population and climate predictions, land use and budgetary

constraints and the ‘connectivity’ between GIs into the decision making process of

GI placement on a county or city scale land area. The proposed approach is tested

on data from a real county to evaluate its utility.

1 - Link Prediction In Multi-relational Networks For Online

Health Communities

Online Health Communities (OHCs) are a popular resource for those with health

problems to exchange information and support. Users often interact via multiple

communication channels, such as online discussions, blogs, and private messages.

Connections among users via different channels form a multi-relational social

network. Using data from a smoking cessation network, this study aims to predict

links between users in one sub-network based on information from other sub-

networks. Our findings regarding tie formation will inform the development and

ongoing management of online health communities.
