Stroke Survivors Control The Temporal Structure Of Variability During Reaching In Dynamic Environments, Mukul Mukherjee, Panagiotis Koutakis, K.-C. Siu, Pierre B. Fayad, Nikolaos Stergiou

Journal Articles

Learning to control forces is known to reduce the amount of movement variability (e.g., standard deviation; SD) while also altering the temporal structure of movement variability (e.g., approximate entropy; ApEn). Such variability control has not been explored in stroke survivors during reaching movements in dynamic environments. Whether augmented feedback affects such variability control, is also unknown. Chronic stroke survivors, assigned randomly to a control/experimental group, learned reaching movements in a dynamically changing environment while receiving either true feedback of their movement (control) or augmented visual feedback (experimental). Hand movement variability was analyzed using SD and ApEn. A significant change in …

The Appropriate Use Of Approximate Entropy And Sample Entropy With Short Data Sets, Jenna M. Yentes, Nathaniel Hunt, Kendra K. Schmid, Jeffrey P. Kaipust, Denise Mcgrath, Nikolaos Stergiou

Journal Articles

Approximate entropy (ApEn) and sample entropy (SampEn) are mathematical algorithms created to measure the repeatability or predictability within a time series. Both algorithms are extremely sensitive to their input parameters: m (length of the data segment being compared), r (similarity criterion), and N (length of data). There is no established consensus on parameter selection in short data sets, especially for biological data. Therefore, the purpose of this research was to examine the robustness of these two entropy algorithms by exploring the effect of changing parameter values on short data sets. Data with known theoretical entropy qualities as well as experimental …

Industry’S Colonization Of Psychiatry: Ethical And Practical Implications Of Financial Conflicts Of Interest In The Dsm-5, Lisa Cosgrove, Emily E. Wheeler

Counseling, School Psychology & Sport Faculty Publication Series

The revision of the Diagnostic and Statistical Manual of Mental Disorders (DSM), scheduled for publication in May 2013 by the American Psychiatric Association (APA), has created a firestorm of controversy because of questions about undue industry influence. Specifically, concerns have been raised about financial conflicts of interest between DSM-5 panel members and the pharmaceutical industry. The authors argue that current approaches to the management of these relationships, particularly transparency of them, are insufficient solutions to the problem of industry’s capture of organized psychiatry. The conceptual framework of institutional corruption is used to understand psychiatry’s dependence on the pharmaceutical industry and …

The Schrödinger Equation With Friction From The Quantum Trajectory Perspective, Sophya V. Garashchuk, Vaibhav Dixit, Bing Gu, James Mazzuca

Faculty Publications

Similarity of equations of motion for the classical and quantum trajectories is used to introduce afriction term dependent on the wavefunction phase into the time-dependent Schrödingerequation. The term describes irreversible energy loss by the quantum system. The force offriction is proportional to the velocity of a quantum trajectory. The resulting Schrödinger equationis nonlinear, conserves wavefunction normalization, and evolves an arbitrary wavefunction into the ground state of the system (of appropriate symmetry if applicable). Decrease in energy is proportional to the average kinetic energy of the quantum trajectory ensemble. Dynamics in the high friction regime is suitable for simple models of …

Personalized Medicine, Genetic Exceptionalism, And The Rule Of Law: An Analysis Of The Prevailing Justification For Invalidating Brca1/2 Patents In Association Of Molecular Pathology V. Uspto, Kristen L. Burge

Washington Journal of Law, Technology & Arts

As medicine advances toward a more personalized model, the significance of genetic information is growing exponentially. While unlocking the genetic code has advanced the state of medicine, it has also reinvigorated the debate over the boundaries of patentable subject matter. The potential clash between having access to state-of-the-art medicine and protecting intellectual property investments came to a head in the case, Association of Molecular Pathology v. USPTO (“Myriad”). This Article analyzes the legal opinion rendered by the district court through the unique lens of genetic exceptionalism—a concept previously reserved to social science and public policy. Then, this Article …

Federal Constitutional Childcare Interests And Superior Parental Rights In Illinois, Jeffrey A. Parness

Northern Illinois University Law Review

The U.S. Supreme Court has long recognized federal constitutional childcare rights in parents that may not be easily diminished or eliminated by government. Yet it has allowed these childcare rightsholders to be chiefly defined by state laws. The relevant state laws vary widely, dependent upon such factors as biological ties, functional parenthood, contracts, and the avenues to conception. Deference to state lawmaking here is unique. No other federal constitutional rightsholders are so significantly defined by state statutes and precedents. This deference has resulted in significant interstate variations in de facto parent, equitable adoption, presumed parent and surrogacy matters, as well …

Changes In Bacterial Growth Rate Govern Expression Of The Borrelia Burgdorferi Ospc And Erp Infection-Associated Surface Proteins, Brandon L. Jutras, Alicia M. Chenail, Brian Stevenson

Microbiology, Immunology, and Molecular Genetics Faculty Publications

The Lyme disease spirochete controls production of its OspC and Erp outer surface proteins, repressing protein synthesis during colonization of vector ticks but increasing expression when those ticks feed on vertebrate hosts. Early studies found that the synthesis of OspC and Erps can be stimulated in culture by shifting the temperature from 23°C to 34°C, leading to a hypothesis that Borrelia burgdorferi senses environmental temperature to determine its location in the tick-mammal infectious cycle. However, borreliae cultured at 34°C divide several times faster than do those cultured at 23°C. We developed methods that disassociate bacterial growth rate and temperature, allowing …

No crayfish or mussel veligers were collected and no non-native zooplankton species were encountered.

Arabidopsis Scaffold Protein Rack1a Interacts With Diverse Environmental Stress And Photosynthesis Related Proteins, Hemayet Ullah

Department of Biology Faculty Publications

Scaffold proteins are known to regulate important cellular processes by interacting with multiple proteins to modulate molecular responses. RACK1 (Receptor for Activated C Kinase 1) is a WD-40 type scaffold protein, conserved in eukaryotes, from Chlamydymonas to plants and humans, expresses ubiquitously and plays regulatory roles in diverse signal transduction and stress response pathways. Here we present the use of Arabidopsis RACK1A, the predominant isoform of a 3-member family, as a bait to screen a split-ubiquitin based cDNA library. In total 97 proteins from dehydration, salt stress, ribosomal and photosynthesis pathways are found to potentially interact with RACK1A. False positive …

Complex Facilitation And Competition In A Temperate Grassland: Loss Of Plant Diversity And Elevated Co2 Have Divergent And Opposite Effects On Oak Establishment, Alexandra Wright, Stefan A. Schnitzer, Ian A. Dickie, Alex R. Gunderson, Gavriella A. Pinter, Scott A. Mangan, Peter B. Reich

Biological Sciences Faculty Research and Publications

Encroachment of woody vegetation into grasslands is a widespread phenomenon that alters plant community composition and ecosystem function. Woody encroachment is often the result of fire suppression, but it may also be related to changes in resource availability associated with global environmental change. We tested the relative strength of three important global change factors (CO₂ enrichment, nitrogen deposition, and loss of herbaceous plant diversity) on the first 3 years of bur oak (Quercus macrocarpa) seedling performance in a field experiment in central Minnesota, USA. We found that loss of plant diversity decreased initial oak survival but increased …

Is Torture Justified In Terrorism Cases?: Comparing U.S. And European Views, Stephen Hoffman

Northern Illinois University Law Review

Popular opinion regarding torture has changed significantly in the wake of 9/11 and subsequent terrorist attacks, with people in affected countries generally becoming more accepting of it as an interrogation tactic. This increase is especially notable where the torture of a few can save the lives of many, particularly where there is little time to pursue other, less-invasive means of interrogation—the so-called “ticking bomb” scenario. This Article discusses three key ethical theories of torture and compares the legal status of torture in the United States and the European Union, concluding that circumstances may require its use when necessary to save …

Laser Wind Sensor Performance Validation With An Existing Gage, Charles R. Standridge, David Zeitler, Erik Nordman, T. Arnold Boezaart, Jim Edmonson, Yeni Nieves, T. J. Turnage, Reo Phillips, Graham Howe, Guy Meadows, Aline Cotel, Frank Marsik, Neel Desai

Reports

A new approach to laser wind sensor measurement validation is described and demonstrated. The new approach relies on the paired-t statistical method to generate a time series of differences between two sets of measurements. This series of differences is studied to help identify and explain time intervals of operationally significant differences, which is not possible with the traditional approach of relying on the squared coefficient of variation as the primary metric. The new approach includes estimating a confidence interval for the mean difference and establishing a level of meaningful difference for the mean difference, and partitioning the data set based …

Differential Regulation Of Glut1 Activity In Human Corneal Limbal Epithelial Cells And Fibroblasts, David P. Kuipers, Jared P. Scripture, Stephen M. Gunnink, Matthew J. Salie

University Faculty Publications and Creative Works

The corneal epithelial tissue is a layer of rapidly growing cells that are highly glycolytic and express GLUT1 as the major glucose transporter. It has been shown that GLUT1 in L929 fibroblast cells and other cell lines can be acutely activated by a variety agents. However, the acute regulation of glucose uptake in corneal cells has not been systematically investigated. Therefore, we examined glucose uptake in an immortalized human corneal-limbal epithelial (HCLE) cell line and compared it to glucose uptake in L929 fibroblast cells, a cell line where glucose uptake has been well characterized. We report that the expression of …

A Novel Approach To A Wearable Eye Tracker Using Region-Based Gaze Estimation, Aun Kei Hong

Theses

Eye tracking studies are useful to understand human behavior and reactions to visual stimuli. To conduct experiments in natural environments it is common to use mobile or wearable eye trackers. To ensure these systems do not interfere with the natural behavior of the subject during the experiment, they should be comfortable and be able to collect information about the subject's point of gaze for long periods of time. Most existing mobile eye trackers are costly and complex. Furthermore they partially obstruct the visual field of the subject by placing the eye camera directly in front of the eye. These systems …

Tree-Structured Small-World Connected Wireless Network-On-Chip With Adaptive Routing, Andrew Benjamin

Theses

Traditional Network-on-Chip (NoC) systems comprised of many cores suffer from debilitating bottlenecks of latency and significant power dissipation due to the overhead inherent in multi-hop communication. In addition, these systems remain vulnerable to malicious circuitry incorporated into the design by untrustworthy vendors in a world where complex multi-stage design and manufacturing processes require the collective specialized services of a variety of contractors. This thesis proposes a novel small-world tree-based network-on-chip (SWTNoC) structure designed for high throughput, acceptable energy consumption, and resiliency to attacks and node failures resulting from the insertion of hardware Trojans. This tree-based implementation was devised as a …

Continuous, Pulsed And Disrupted Nutrient Subsidy Effects On Ecosystem Productivity, Stability, And Energy Flow, Michael J. Weber, Michael L. Brown

Natural Resource Management Faculty Publications

Resource pulses and subsidies can supply ecosystems with an important source of nutrients that supports additional productivity at multiple trophic levels. Common carp Cyprinus carpio provide ecosystems with a continuous nutrient subsidy through bioturbation and excretion but may also initiate a nutrient pulse through carcass decomposition. We examined how continuous (common carp foraging and excretion), pulsed (carcass decomposition) and disrupted (carp introduced and then removed) nutrient subsidies differed in their ability to alter nutrient availability, ecosystem productivity and stability and energy flow. Nitrogen and phosphorus availability and primary production were highest in pulsed, intermediate in continuous and lowest for disrupted …
