Title Towards a Biometric Authentication-based Hybrid Trust-computing Approach for Verification of Provider Profiles in Online Healthcare Information.
Citation 38th IEEE Symposium on Security and Privacy (IEEE S&P) Workshop on Bio-inspired Security, Trust, Assurance and Resilience (BioSTAR). 2017; 2. Chattopadhyay A, Schulz M, Rettler C, Turkiewicz K, Fernandez L, Ziganshin A. University of Wisconsin-Green Bay.
Description With growth in the use of cyberspace by consumers for online healthcare information (OHI), various researchers from different disciplines have been working on the challenges and threats posed by cyberchondria. However, there are few research efforts, which have directly treated the case of cyberchondria as an interdisciplinary trust-computing problem in information assurance, and have encountered the reliability issues with OHI by handling provider level trust antecedents. OHI based trust research has never used biometrics to validate multidimensional trust constructs, and has not handled trustworthiness at the provider level through verification of institutional profiles and affiliations. This paper conceptualizes and proposes a novel trust-computing model, which is driven by visual recognition based biometric authentication of physician profiles.

Title Model Averaging with AIC Weights for Hypothesis Testing of Hormesis at Low Doses.
Citation Dose-Response. 2017; 15:2:1559325817715314. Kim S, Sanders N. California State University, Monterey Bay
Description In sparse data, it is difficult to detect a non-monotonic dose-response relationship (known as hormesis). To gain statistical efficiency (i.e., greater statistical power in hypothesis testing), parametric models are often considered in practice. In this research, we illustrated potential caveats in the use of a parametric model, and we proposed a model-averaging method for robust hypothesis testing. Our simulation study showed that the model-averaging method provides a robust result when the true dose-response relationship does not follow a parametric assumption.

Title Androids Armed with Poisoned Chocolate Squares: Ideal Nim and Its Relatives
Citation Mathematics Magazine (A Journal of the Mathematical Association of America), 2016; 89: 4:235-250, doi: 10.4169/math.mag.89.4.235. Dozier H, Perry J. University of Southern Mississippi.
Description The authors describe two new combinatorial games. The first, Ideal Nim, both generalizes the well-known game Nim and its relative Chomp, and provides a recreational perspective on some important ideas of commutative algebra; for instance, the fact that the game is guaranteed to end is equivalent to Dickson’s lemma, a well-known fact of commutative algebra. This relationship leads to a game-based proof of Dickson’s lemma. The second game, Gröbner Nim, is really a variant of Ideal Nim that illustrates Buchberger’s algorithm to compute a Gröbner basis. The authors conclude by describing the relationship between Gröbner Nim and polynomial rings.
Faculty John Perry is an associate professor of mathematics.
Student Haley Dozier worked on the project from 2013 to 2014 and presented her work at the annual meeting of the LA/MS Section of the Mathematical Association of America.

Title Investigating Anthropogenic Mammoth Extinction with Mathematical Models
Citation Spora - A Journal of Biomathematics., 2015; 1: 8-16, Frank M, Slaton A, Tinta T, Capaldi A.. Valparaiso University

Title Optimal prediction of moving sound source direction in the owl
Citation PLoS Computational Biology, 2015; 11: 7:NA, Cox W, Fischer BJ. Seattle University
Description Predictive movements are especially important in prey capture where a predator must predict the future location of moving prey. How sensory information is transformed to motor commands for predictive behaviors is an important open question. We used a theoretical approach to specify how a population of neurons should respond to a moving stimulus to allow for a Bayesian prediction to be decoded from the neural responses. This provides a novel theoretical framework that predicts properties of neural responses that are observed in auditory and visual systems of multiple species.

Citation Groups Complexity Cryptology, 2014; 6: 1:1867-1144, Babinkostova L., Bombardier KW, Cole MC, Morrell TA and Scott CB. Boise State University
Description AES (Advanced Encryption Standard) is a block cipher chosen in 2001 as the United States’ official symmetric key cryptosystem for Top Secret information. Although all current attacks on AES are too slow to be practical, there are theoretical attacks that raise concern about the long term security of AES. A motivation for investigating the group theoretic structure of AES and alternative platforms and specifications is to identify and exclude properties that can be exploited to undermine the security of such systems. In this paper we examine such conditions for AES-like systems over several mathematical platforms.

Title New results on an anti-Waring problem
Citation Involve, 2014; 7: 2:239-244, Fuller C, Prier DR, Vasconi KA.. Gannon University
Description The number N(k,r) is defined to be the first integer such that it and every subsequent integer can be written as the sum of the k-th powers of r or more distinct positive integers. For example, it is known that N(2,1) = 129, and thus the last number that cannot be written as the sum of one or more distinct squares is 128. This paper give a proof of a theorem that states if certain conditions are met, a number can be verified to be N(k,r). We then use that theorem to find N(2,r) for values between 1 and 50 and N(3,1) for values between 1 and 30.

Citation 35th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2013; 1: 2419 - 2422, Fu JC, Hao W, White T, Yan YQ, Jones M, Jan YK. University of Central Oklahoma
Description Power wheelchairs have been widely used to provide independent mobility to people with disabilities. Despite great advancements in power wheelchair technology, research shows that wheelchair related accidents occur frequently. To ensure safe maneuverability, capturing wheelchair maneuvering patterns is fundamental to enable other research, such as safe robotic assistance for wheelchair users. In this study, we propose to record, store, and analyze wheelchair maneuvering data by means of mobile cloud computing. Specifically, the accelerometer and gyroscope sensors in smart phones are used to record wheelchair maneuvering data in real-time. Then, the recorded data are periodically transmitted to the cloud for storage and analysis. The analyzed results are then made available to various types of users, such as mobile phone users, traditional desktop users, etc. The combination of mobile computing and cloud computing leverages the advantages of both techniques and extends the smart phone’s capabilities of computing and data storage via the cloud.

Citation IEEE International Conference on Tools with Artificial Intelligence (ICTAI) - 2013, 2013; 1: 87-94, Fu JC, Jaramillo AC, Ng V, Bastani FB, and Yen IL. University of Central Oklahoma
Description We present a planner for addressing a difficult, yet under-investigated class of planning problems: Fully Observable Non-Deterministic planning problems with strong solutions. Our strong planner employs a new data structure, MRDAG (multi-root directed acyclic graph), to define how the solution space should be expanded. We further equip a MRDAG with heuristics to ensure planning towards the relevant search direction. We performed extensive experiments to evaluate MRDAG and the heuristics. Results show that our strong algorithm achieves impressive performance on a variety of benchmark problems: on average it runs more than three orders of magnitude faster than the state-of-the-art planners, MBP and Gamer, and demonstrates significantly better scalability.

Citation Proceedings of the 2013 IEEE 27th International Conference on Advanced Information Networking and Applications, 2013; 1: 185-190, Garant D, Lu, W.. Keene State College, University System of New Hampshire
Description Recognized as one of the most serious security threats on current Internet infrastructure, botnets are often hidden in existing applications, e.g. IRC, HTTP, or peer-to-peer, which makes botnet detection a challenging problem. In this work a new, centralized, fully-encrypted, botnet system called Weasel is proposed, including a set of signatures for differentiating the behaviors of Weasel and normal web applications, and a set of data mining techniques for detecting the web based botnet behaviors. The proposed approach was evaluated with over 400 thousand flows collected over seven consecutive days on a large scale network and results show the proposed approach successfully detects the botnet flows with a high detection rate and an acceptably low false alarm rate.

Title The Impact of Temperature on Major League Baseball
Citation AMS Journal: Weather, Climate, and Society., 2013; 5: 4:Koch, BLD, Panorska, AK.. University of Nevada Reno
Description Major League Baseball is played every year, encompassing three meteorological seasons: spring, summer, and fall. The 30 teams play in cities across the United States and Canada in many types of weather. This work studies the impact of temperature on a Major League Baseball game by examining the association between temperature and several baseball statistics, including runs scored, batting average, slugging percentage, on-base percentage, home runs, walks, strikeouts, hit-batsmen, stolen bases, and errors. Home and away teams’ performances were analyzed separately. The results of this study show that runs scored, batting average, slugging percentage, on-base percentage, and home runs significantly increase while walks significantly decrease in warm weather compared to cold weather.

Title Block Modeling in Large Social Networks with Many Clusters
Citation AAAI Fall Symposium Series., 2012; 0: 0:Shawn Biesan, Adam Anthony, Marie desJardins.. Baldwin-Wallace University
Description This paper presents an optimized form of Block Modularity. The original algorithm was a fast, greedy method that effectively discovered a structured clustering in linked data and scaled very well with the number of nodes and edges. The optimized version is scalable in terms of the model complexity; the technique can now be used effectively to discover thousands of clusters in data sets with hundreds of thousands (and possibly more) nodes and edges.

Title A Population-based Evolutionary Algorithm for Sampling Minima in the Protein Energy Surface
Citation Comput Struct Biol Workshop at IEEE BIBM, 2012; 6: Saleh S, Olson B, Shehu A.. George Mason University
Description Predicting the native tertiary structure of a protein from its amino-acid sequence is a central problem in computational biology but difficult due to the high dimensionality of the protein conformational space and ruggedness of the associated energy surface. This paper proposes a Memetic Evolutionary Algorithm (MEA) to sample a diverse ensemble of low-energy conformations that represent local minima in the protein energy surface. The method combines a population-based approach with an internal local greedy search to obtain diverse local minima. The molecular fragment replacement technique and a state-of-the-art coarse grained energy function allow obtaining physically-realistic conformations. A detailed analysis of the ensemble of conformations obtained by the method on reveals that the method enhances sampling of near-native conformations.

Title An Analysis of Heat Explosion for Thermally Insulated and Conducting Systems
Citation Applied Mathematics., 2012; 3: 6:535-540, Fairchild K, Scruggs M, Viktorova I, Zeller I.. Clemson University
Description The goal for this paper is improving mathematical models predicting heat explosion by using a specific case of the Fourier heat transfer system that focuses on thermoviscoelastic properties of materials. This is done by using a computational analysis to solve for an internal heat parameter that determines thermal failure at a critical value. This critical value is calculated under conditions either accounting for or negating the effect of heat dissipated by the material. This model is an improvement on existing models because it accounts for material specific properties and in doing so limits mathematical assumptions of the system. By limiting the assumptions in the conditions of the model, the model becomes more accurate and useful in regards to material design.

Description The paper evaluates a developmental network model of life-history traits based on A. lyrata, tests the efficacy of structural equation modeling to identify the correct basis for multiple-trait quantitative trait locus effects, and compares model predictions with field data. We found that the trait network constrained the phenotypic covariance patterns to varying degrees. Our results show that causal trait network models can unify several aspects of quantitative genetic theory with empirical observations on genetic and phenotypic covariance patterns, and that incorporating trait networks into genetic analysis offers promise for elucidating mechanisms of life history evolution.

Title Using Artificial Neural Network To Determine Favorable Wheelchair Tilt and Recline Usage in People with Spinal Cord Injury
Citation 23rd IEEE International Conference on Tools with Artificial Intelligence, 2011; 1: 25-32, Fu JC, Genson J, Jan YK, Jones M.. University of Central Oklahoma and University of Oklahoma Health Sciences Center
Description People with spinal cord injury (SCI) are at risk for pressure ulcers because of their poor motor function and consequent prolonged sitting in wheelchairs. It is estimated that more than 50% of the people with SCI will develop at least one pressure ulcer in their lifetimes. It is clear that research regarding the prevention of pressure ulcers remains a priority in people with SCI. The current clinical practice uses the wheelchair tilt and recline to reduce seating pressure to prevent pressure ulcers. We use artificial neural networks (ANNs) to classify whether a given tilt and recline setting would be favorable to reduce pressure ulcers risk. The genetic algorithm (GA) was used to train ANN to improve the classification accuracy.

Description The research project determined combinatorial design constraints for self-assembling nanostructures based on branched junction DNA molecules utilizing the geometric structure of portions of an octet truss. We proposed a lexicographical naming scheme for tiles (single junctions and their attached half arms) and defined the canonical form of a set of geometrically isomorphic tiles as the lexicographically minimal element of the set. We then provided construction strategies for Archimedean and Platonic solids naturally occurring in the octet truss which are provably optimized to minimize the number of distinct tile types used in assembly.
