Byu Adds "Zing" To New Carbonated Yogurt Product In Stores Nationwide, Byu News
Faculty Publications
A BYU professor invented the "zing" in General Mills' new carbonated yogurt product, now available in stores all over the country. Fizzix(TM), an extension of Yoplait's Go-GURT brand that comes in a tube, adds a tangy tingle to the traditional fruity flavor of yogurt that will "fizzify" the tongues of the 8- to 12-year-olds the company is targeting.
Novel Perturbation Approach For The Structure Factor Of The Attractive Hard-Core Yukawa Fluid, Andrij Trokhymchuk, Roman Melnyk, Filip Moucka, Ivo Nezbeda
Novel Perturbation Approach For The Structure Factor Of The Attractive Hard-Core Yukawa Fluid, Andrij Trokhymchuk, Roman Melnyk, Filip Moucka, Ivo Nezbeda
Faculty Publications
A novel perturbation approach for the structure factor S(k) of the Lennard-Jones-type Yukawa fluid with z=1.8 is presented. An approach is based on a new reference system, that is, the short-range Yukawa model with z0 > z=1.8. By choosing for the reference system the value z0=6, it is shown that (i) the proposed approach for S(k) performs much better than the traditional hard-sphere reference perturbation method does; (ii) the use of an approximate mean spherical (MSA) description of the reference structure factor provides the results for S(k) that are more accurate as those obtained from the direct MSA computations; and (iii) …
Hardness For Explicit State Software Model Checking Benchmarks, Eric G. Mercer, Neha Rungta
Hardness For Explicit State Software Model Checking Benchmarks, Eric G. Mercer, Neha Rungta
Faculty Publications
Directed model checking algorithms focus computation resources in the error-prone areas of concurrent systems. The algorithms depend on some empirical analysis to report their performance gains. Recent work characterizes the hardness of models used in the analysis as an estimated number of paths in the model that contain an error. This hardness metric is computed using a stateless random walk. We show that this is not a good hardness metric because models labeled hard with a stateless random walk metric have easily discoverable errors with a stateful randomized search. We present an analysis which shows that a hardness metric based …

Differential Resource Allocation In Deer Mice Exposed To Sin Nombre Virus, Eric Wilson, Erin M. Lehmer, Christine A. Clay, Stephen St. Jeor, Denise M. Dearing
Faculty Publications
The resource allocation hypothesis predicts that reproductive activity suppresses immunocompetence; however, this has never been tested in an endemic disease system with free-ranging mammals. We tested the resource allocation hypothesis in wild deer mice (Peromyscus maniculatus) with natural exposure to Sin Nombre Virus (SNV). Immunocompetence was estimated from the extent of swelling elicited after deer mice were injected with phytohemagglutinin (PHA); swelling is positively correlated with immunocompetence. After livetrapping deer mice, we determined their reproductive state and SNV infection status. Males were more likely to be seropositive for SNV than females (37% vs. 25%) and exhibited 10% less swelling after …
Poisson Disk Point Sets By Hierarchical Dart Throwing, David Cline, Parris K. Egbert, Kenric B. White
Poisson Disk Point Sets By Hierarchical Dart Throwing, David Cline, Parris K. Egbert, Kenric B. White
Faculty Publications
Poisson disk point sets are “ideally” generated through a process of dart throwing. The naive dart throwing algorithm is extremely expensive if a maximal set is desired, however. In this paper we present a hierarchical dart throwing procedure which produces point sets that are equivalent to naive dart throwing, but is very fast. The procedure works by intelligently excluding areas known to be fully covered by existing samples. By excluding covered regions, the probability of accepting a thrown dart is greatly increased. Our algorithm is conceptually simple, performs dart throwing in O(N) time and memory, and produces a maximal point …
Image-Based Color Schemes, Bryan S. Morse, Daniel Thornton, Qing Xia, John Uibel
Image-Based Color Schemes, Bryan S. Morse, Daniel Thornton, Qing Xia, John Uibel
Faculty Publications
This paper presents a novel method for generating color schemes based on images intended to anchor color designs. This has wide applicability for web pages, printed materials, or other applications where images are used as a key part of the overall design. Unlike methods that are variants of color quantization and try to pixel-wise approximate the image, this method draws on graphic-design principles by emphasizing hue selection first, weighting effects of color by saturation, and considering the local spatial coherency in order to determine the overall visual impact of a color. Results demonstrate that the method generalizes to a wide …
Provincial Development In China: Lessons From Eu Regional Policy Experience, Phillip J. Bryson, Keren Sun
Provincial Development In China: Lessons From Eu Regional Policy Experience, Phillip J. Bryson, Keren Sun
Faculty Publications
Regional development in the Chinese provinces and in the regions of the EU countries are evaluated and compared. Development efforts in southern Italy, northeast England and eastern Germany are reviewed along with EU, Community-wide regional development programs. Equity concerns suggest promotion of regional policy, but the pursuit of maximum national economic growth would avoid it, since it sacrifices some economic growth. The impact of FDI and domestic investments on individual Chinese provinces is compared with their impact in Europe. There is an implicit contrast between public sector regional development programs and more effective private foreign direct investments.
Using Fuzzy-Word Correlation Factors To Compute Document Similarity Based On Phrase Matching, Jun Won Lee, Yiu-Kai D. Ng
Using Fuzzy-Word Correlation Factors To Compute Document Similarity Based On Phrase Matching, Jun Won Lee, Yiu-Kai D. Ng
Faculty Publications
One of the Web information Retrieval (IR) problems these days is to identify redundant information that exist in (replicated) Web documents. These documents can easily be found in several forms, such as documents in different versions, small documents combined with others to form a larger document, etc. As the Web is becoming more and more popular, the number of documents on the Web is increasing on a daily basis, and filtering redundant ones among this huge number of documents becomes a more difficult and an urgent task. As one of the solutions to this problem, we present a new method …

Constructing Subdivision Rules From Rational Maps, J. W. Cannon, W. J. Floyd, W. R. Parry
Faculty Publications
This paper deepens the connections between critically finite rational maps and finite subdivision rules. The main theorem is that if f is a critically finite rational map with no periodic critical points, then for any sufficiently large integer n the iterate f is the subdivision map of a finite subdivision rule. This enables one to give essentially combinatorial models for the dynamics of such iterates.

Associations Between Shyness And Internalizing Behaviors, Externalizing Behaviors, And Relationships During Emerging Adulthood, Larry J. Nelson, Laura M. Padilla-Walker, Sarah Badger, Carolyn Mcnamara Barry, Jason S. Carroll, Stephanie D. Madsen
Faculty Publications
Many studies have documented the ways in which shyness can be a barrier to personal well-being and social adjustment throughout childhood and adolescence; however, less is known regarding shyness in emerging adulthood. Shyness as experienced during emerging adulthood may continue to be a risk factor for successful development. The purpose of this study was to compare shy emerging adults with their non-shy peers in (a) internalizing behaviors, (b) externalizing behaviors, and (c) close relationships. Participants included 813 undergraduate students (500 women, 313 men) from a number of locations across the United States. Results showed that relatively shy emerging adults, both …

Quinoa (Chenopodium quinoa Willd.) is a staple food crop for millions of impoverished rural inhabitants of Andean South America where it has been cultivated for millennia. Interest in quinoa, due largely to its superior nutritional characteristics, is fuelling a growing export market and has led to an increased focus on genetic research and the development of quinoa breeding programmes throughout South America. The success of these breeding programmes will rely heavily on the development of core germplasm collections and germplasm conservation. We report the development of a set of fluorescence-tagged microsatellite molecular markers that can be used to characterize genetic …
Quality Of Hermetically Packaged Dehydrated Carrots During Long-Term Storage, S. R. Bartholomew, Laura K. Jefferies, Oscar A. Pike
Quality Of Hermetically Packaged Dehydrated Carrots During Long-Term Storage, S. R. Bartholomew, Laura K. Jefferies, Oscar A. Pike
Faculty Publications
There is interest in the long-term storage of food for applications such as space flight, disaster relief, and personal preparedness. Dehydrated carrots packaged in hermetically sealed cans with a reduced oxygen atmosphere are available in the retail market. The quality of dehydrated carrots stored up to two years has been reported, but the effect of longer-term storage on the quality of the product is unknown. Eleven samples of dehydrated carrots representing 6 brands, packaged in size No.10 cans and stored at room temperature, were obtained from donors. Two fresh samples were purchased as controls. Samples ranged in age from < 1 to 34 years. Can headspace oxygen, can seam integrity, and dehydrated carrot water activity and color were evaluated. Samples were rehydrated for 20 minutes in filtered water that was brought to a boil. A 56-member consumer panel evaluated the rehydrated carrots for appearance, aroma, texture, flavor, and overall acceptability using a 9-point hedonic scale. Acceptance for use in everyday and emergency situations was also determined. Can headspace oxygen ranged from < 0.01% to 14.7%. All can seams were determined to be satisfactory. Water activity of the dehydrated carrots ranged from 0.31 to 0.38. L*, a* and b* values ranged from 37.8 to 44.0, 17.1 to 30.2 and 23.0 to 37.3, respectively. The orange color of most samples faded during storage. Hedonic scores for overall acceptability of dehydrated carrots declined from 7.1 to 3.4. All samples had an acceptance for use in an emergency situation of over 70%. Results indicate that dehydrated carrots decline in quality during long-term storage but retain sufficient sensory acceptance to be considered for use in long-term storage regimens.

Quality Of Hermetically Packaged Split Peas During Long-Term Storage, J. S. Chapman, Laura K. Jefferies, Oscar A. Pike
Faculty Publications
There is a market for low moisture foods that can be stored for long periods of time for use in disaster relief and other emergency situations. Split peas hermetically sealed in cans with a reduced oxygen atmosphere are available in the retail market, but the effect of long-term storage on the quality of the product is unknown. Ten samples of split peas representing 5 retail brands packaged in size No.10 cans and stored at room temperature were obtained from donors. Two fresh samples of split peas were purchased as controls. Samples ranged in age from <1 to 34 years. Can headspace oxygen, can seam integrity, and split pea water activity and color were evaluated. A 52-member consumer panel evaluated the samples, prepared as split pea soup, for appearance, aroma, texture, flavor, and overall acceptability using a 9-point hedonic scale. Acceptance for use in everyday and emergency situations was also determined. Can headspace oxygen ranged from 0.19 to 20.1%. All can seams were determined to be satisfactory. Water activity of the raw split peas ranged from 0.41 to 0.56. The green color of raw split peas decreased over time as shown by increasing CIE a* values. Flavor, appearance, texture, and overall acceptability hedonic scores ranged from 6.7 to 4.4 and decreased over time. Hedonic scores for appearance were correlated with the decrease in raw product green color (r2 = .928). Hedonic scores for texture declined over time, corresponding with increasing hardness of the peas. All samples had an acceptance in an emergency situation of over 75%. Results indicate split pea quality declines over time, but the product maintains sufficient sensory acceptance to be considered for use in applications requiring long-term storage.

The Decline Of The American Superpower, Earl H. Fry
Faculty Publications
By 2040, the United States will no longer be considered as a global superpower and the world may be headed toward a long era devoid of any superpowers. This will occur as a result of several negative trends within the United States itself, combined with changing dynamics and exigencies in the global system and the rise of more powerful competitors in Asia and Europe. The negative trends within the United States include unprecedented governmental and international debt, dysfunctional campaign-finance and lobbying systems, unmanageable entitlement and health-care obligations, a deteriorating public education network, an inordinate concentration of wealth and power in …
A Dynamic Attribute-Based Load Shedding Scheme For Data Stream Management Systems, Amit Ahuja, Yiu-Kai D. Ng
A Dynamic Attribute-Based Load Shedding Scheme For Data Stream Management Systems, Amit Ahuja, Yiu-Kai D. Ng
Faculty Publications
A data stream being transmitted over a network channel with capacity less than the data transmission rate of the data stream causes sequential network problems. In this paper, we present a new approach for shedding less-informative attribute data from a data stream to maintain a data transmission rate less than the network channel capacity. A scheme for shedding attributes and their data, instead of tuples, becomes imperative in data stream load shedding, since shedding a complete tuple would lead to shedding informative attribute data along with less-informative attribute data in the tuple. Our load shedding approach handles intra-stream, as well …
Henry George: The Theory Of Distribution In Progress And Poverty, Phillip J. Bryson
Henry George: The Theory Of Distribution In Progress And Poverty, Phillip J. Bryson
Faculty Publications
The core of Henry George's economic theory appeared in his most widely-read book, Progress and Poverty. On the basis of his dramatic "single tax" theory, his work became widely known and gained some avid followers who endeavored to base policy on it. But the work was also of value in George's day and interest in our day because of its economic content. George was not a part of the academic economics establishment of his day and his theory was of strictly classical methodology, but it still had much to commend it. A simple model to present his concepts in more …

Information Consensus And Its Application In Multi-Vehicle Cooperative Control, Ella Atkins, Randal Beard, Wei Ren
Faculty Publications
In the last two decades, advances in networking and distributed computing have facilitated a paradigm shift from large, monolithic mainframe computers to networks of less expensive, less powerful workstations. One motivation for multi-vehicle systems is to achieve the same gains for mechanically controlled systems as has been gained in distributed computation. Rather than having a single monolithic (and therefore expensive and complicated) machine do everything, the hope is that many inexpensive, simple machines, can achieve the same, or enhanced functionality, through coordination. In essence, the objective is to replace expensive complicated hardware with software and multiple copies of simple hardware. …

Using Box-Scores To Determine A Position's Contribution To Winning Basketball Games, Gilbert W. Fellingham, C. Shane Reese, Garritt L. Page
Faculty Publications
While it is generally recognized that the relative importance of different skills is not constant across different positions on a basketball team, quantification of the differences has not been well studied. 1163 box scores from games in the National Basketball Association during the 1996-97 season were used to study the relationship of skill performance by position and game outcome as measured by point differentials. A hierarchical Bayesian model was fit with individual players viewed as a draw from a population of players playing a particular position: point guard, shooting guard, small forward, power forward, center, and bench. Posterior distributions for …

Time-Varying Mimo Channels: Parametric Statistical Modeling And Experimental Results, Michael A. Jensen, Shuangquan Wang, Ali Abdi, Jari Salo, Hassan M. El-Sallabi, Jon W. Wallace, Pertti Vainikainen
Faculty Publications
Accurate characterization of multiple-input multiple-output (MIMO) fading channels is an important prerequisite for the design of multiantenna wireless-communication systems. In this paper, a single-bounce two-ring statistical model for the time-varying MIMO flat fading channels is proposed. In the model, both the base and mobile stations are surrounded by their own ring of scatterers. For the proposed model, a closed-form expression for the spatio-temporal cross-correlational function between any two subchannels is derived, assuming single-bounce scattering. The new analytical expression includes several key physical parameters of interest such as the mean angle-of-departure, the mean angle-of-arrival, the associated angle spreads, and the Doppler …
Putting Emotional Reactivity In Its Place? Exploring Family-Of-Origin Influences On Emotional Reactivity, Conflict, And Satisfaction In Premarital Couples, Brandt C. Gardner, Dean M. Busby, Andrew S. Brimhall
Putting Emotional Reactivity In Its Place? Exploring Family-Of-Origin Influences On Emotional Reactivity, Conflict, And Satisfaction In Premarital Couples, Brandt C. Gardner, Dean M. Busby, Andrew S. Brimhall
Faculty Publications
The purpose of this research was to develop a structural equation model that tested the effects of emotional reactivity on the relational health of a representative sample of 736 premarital couples. We hypothesized that partners’ perceived family-of-origin experience would be predictive of partners’ reports of their own and their partners’ emotional reactivity. These reports were hypothesized to predict partners’ reports of their own and their partners’ ability to manage conflict, which were hypothesized to predict relationship satisfaction. Overall, the model fit the data quite well, with particularly interesting differences by gender. We discuss the model’s fit within the larger body …

Optimization Of Nano-Magneto-Optic Sensitivity Using Dual Dielectric Layer Enhancement, Aaron R. Hawkins, J. D. Maas, S. Wang, A. Barman, Holger Schmidt, S. Kwon, B. Harteneck, S. Cabrini, J. Bokor
Faculty Publications
We discuss maximization of the sensitivity of magneto-optical detection of single nanomagnets. We show that a combination of optimized dielectric coating on the magnets with an antireflection coated substrate can increase the areal magneto-optic sensitivity by about three orders of magnitude in the deep nanometer range. A dual layer nanofabrication process is developed to implement this approach, and magnetization switching of single nickel nanomagnets with 50 nm diameter is demonstrated.

Earth Science Mini-Lessons: A Service-Learning Strategy For Improving Attitudes Toward Science Of Preservice Elementary Teachers, K. Thompson, B. R. Bickmore, Charles R. Graham, S. C. Yanchar
Faculty Publications
Science instruction in elementary school classrooms is frequently lacking in the United States. One factor that impacts the amount and quality of science instruction is teacher attitudes toward science. The Earth Science Mini-Lesson Project is a strategic program created to help improve preservice elementary school teachers' attitudes toward science in a one-semester college class. Students participating in this project create earth science mini-lessons on topics taken from the Utah Core Curriculum Standards and teach them to elementary students at a local Title I grade school. Attitude survey results from both semesters showed that this service-learning outreach program positively affected students' …
Optimal Noise Matching For Mutually-Coupled Arrays, Michael A. Jensen, Karl F. Warnick
Optimal Noise Matching For Mutually-Coupled Arrays, Michael A. Jensen, Karl F. Warnick
Faculty Publications
From classical two-port noise theory, the noise figure of an amplifier is minimized when a source is matched to a particular optimal reflection coefficient at the amplifier input. In this paper, we show that this result extends in a natural way to the multiport case, with a coupled N-port source network such as an array antenna connected by a multiport matching network to the inputs of N low-noise amplifiers. For optimal noise performance, the matching network must decouple the array and present isolated, individually noise-matched ports to the amplifier inputs.

Active Learning For Part-Of-Speech Tagging: Accelerating Corpus Annotation, George Busby, Marc Carmen, James Carroll, Robbie Haertel, Deryle W. Lonsdale, Peter Mcclanahan, Eric K. Ringger, Kevin Seppi
Faculty Publications
In the construction of a part-of-speech annotated corpus, we are constrained by a fixed budget. A fully annotated corpus is required, but we can afford to label only a subset. We train a Maximum Entropy Markov Model tagger from a labeled subset and automatically tag the remainder. This paper addresses the question of where to focus our manual tagging efforts in order to deliver an annotation of highest quality. In this context, we find that active learning is always helpful. We focus on Query by Uncertainty (QBU) and Query by Committee (QBC) and report on experiments with several baselines and …

At least thirty non-U.S. journalists in the last decade have argued in U.S. Courts of Appeal that U.S. immigration authorities erroneously denied their asylum applications based on persecution in their native countries. ... Still, journalists persecuted in their home countries for their journalism work might better fit the statutory qualifications for asylum --primarily persecution on account of race, religion, nationality, political opinion or membership in a "particular social group"--than the U.S. immigration system sometimes acknowledges. ...

Distinguishing the recent introduction of quinolone resistant gonococci into a population from diversification of resistant strains already in the population is important for planning effective infection control strategies. We applied molecular evolutionary analyses to DNA sequences from 9 housekeeping genes and gyrA, parC and porB of 24 quinolone resistant N. gonorrhoeae (QRNG) and 24 quinolone sensitive isolates collected in Israel during 2000-2001. Results- Phylogenetic and eBURST analyses and estimates of divergence time indicated QRNG were introduced on 3 separate occasions and underwent limited diversification by mutation, deletion and horizontal gene transfer. Reconstruction of N. gonorrhoeae demography showed a slowly declining …

On-Chip Surface-Enhanced Raman Scattering Detection Using Integrated Liquid-Core Waveguides, Aaron R. Hawkins, Evan J. Lunt, Phillip Measor, Leo Seballos, Dongliang Yin, Jin Z. Zhang, Holger Schmidt
Faculty Publications
The authors demonstrate surface-enhanced Raman scattering (SERS) detection on an optofluidic chip. Interconnected solid- and liquid-core antiresonant reflecting optical waveguides (ARROWs) form a planar beam geometry that allows for high mode intensities along microfluidic channels containing molecules optimized for SERS. The excitation power and concentration dependence of SERS from rhodamine 6G (R6G) molecules adsorbed to silver nanoparticles were systematically studied. The data can be described by a model that takes into account the microphotonic structure. Detection sensitivity to a minimum concentration of 30 nM is found, demonstrating the suitability of ARROW-based optofluidic chips for high sensitivity detection with molecular specificity

Size Dependent Damping In Picosecond Dynamics Of Single Nanomagnets, Aaron R. Hawkins, J. D. Maas, S. Wang, A. Barman, Holger Schmidt, Liddle A. Kwon, J. Bokor
Faculty Publications
The authors use time-resolved cavity-enhanced magneto-optical Kerr spectroscopy to study the damping of magnetization precession in individual cylindrical nickel nanomagnets. A wide range of shapes (diameters of 5 µm–125 nm and aspect ratio: 0.03–1.2) is investigated. They observe a pronounced difference in damping between the micro- and nanomagnets. Microscale magnets show large damping at low bias fields, whereas nanomagnets exhibit bias field-independent damping. This behavior is explained by the interaction of in-plane and out-of-plane precession modes in microscale magnets that results in additional dissipative channels. The small and robust damping values on the nanoscale are promising for implementation of controlled …

Values In Family Therapy Practice And Research: An Invitation For Reflection, Stephen T. Fife, Jason B. Whiting Phd
Faculty Publications
Values have been shown to be a pervasive part of both marriage and family therapy (MFT) clinical practice and research. Yet, many therapists and researchers remain unclear about how values affect their work. This article examines the influence of Western philosophical assumptions and therapy traditions in light of current understandings of values in therapy. The influence of values in MFT research processes is similarly examined. Implications for how family therapy professionals can be more reflective and sophisticated in their understanding of values in clinical practice and scientific inquiry are discussed. Suggestions for addressing values in MFT training also are given.
