Toward A New Understanding Of Virtual Research Collaborations: Complex Adaptive Systems Framework, Arsev U. Aydinoglu

DataONE Sociocultural and Usability & Assessment Working Groups

Virtual research collaborations (VRCs) have become an important method of conducting scientific activity; however, they are often regarded and treated as traditional scientific collaborations. Their success is measured by scholarly productivity and adherence to budget by funding agencies, participating scientists, and scholars. VRCs operate in complex environments interacting with other complex systems. A holistic (or organicist) approach is needed to make sense of this complexity. For that purpose, this study proposes using a new perspective, namely, the complex adaptive systems theory that can provide a better understanding of a VRC’s potential creativity, adaptability, resilience, and probable success. The key concepts …

Statistical Ensemble Analysis For Simulating Extrinsic Noise-Driven Response In Nf-Κb Signaling Networks, Jaewook Joo, Steven J. Plimpton, Jean-Loup Faulon

Physics and Astronomy Publications and Other Works

Background

Gene expression profiles and protein dynamics in single cells have a large cell-to-cell variability due to intracellular noise. Intracellular fluctuations originate from two sources: intrinsic noise due to the probabilistic nature of biochemical reactions and extrinsic noise due to randomized interactions of the cell with other cellular systems or its environment. Presently, there is no systematic parameterization and modeling scheme to simulate cellular response at the single cell level in the presence of extrinsic noise.

Results

In this paper, we propose a novel statistical ensemble method to simulate the distribution of heterogeneous cellular responses in single cells. We capture …

An Investigation Into The Sustainability Of Advanced Materials And Systems As Energy Sources In Commuter Transportation, Austin Alan Albert

Chemistry Publications and Other Works

Modern society depends on cheap and plentiful sources of energy. For most of the 20th century, fossil fuel in the form of coal, natural gas, and petroleum have been this energy source. The majority of petroleum in the U.S. goes in to fueling the light duty transportation fleet. However, we know that coal, natural gas, and crude oil have an expiration date, and we have recently learned that their use has caused and is still causing severe damage to the earth’s atmosphere. With these reasons in mind, new sources of inexpensive and abundant energy must be found, which are renewable …

Moving Toward Sustainable Production Of Charcoal In Sub-Saharan Africa: A Teaching Case Study, Justin Taylor Roop

Chemistry Publications and Other Works

In the developing world, wood fuels play a major role in supplying energy needs. In sub-Saharan Africa, much of this wood fuel is in the form of charcoal used for cooking. As much as 90% of the cooking performed in these countries use charcoal as the energy source. With this massive quantity being produced and sold, the charcoal sector presents a major area in which sustainable development can be implemented with a large positive impact. At present, deforestation, pollution, and inequitable distribution of profits threaten the long-term viability of this industry. This teaching case study presents the background of the …

A Southern Hemisphere Origin For Campanulid Angiosperms, With Traces Of The Break-Up Of Gondwana, Jeremy M. Beaulieu, David C. Tank, Michael J. Donoghue

Faculty Publications and Other Works -- Mathematics

Background

New powerful biogeographic methods have focused attention on long-standing hypotheses regarding the influence of the break-up of Gondwana on the biogeography of Southern Hemisphere plant groups. Studies to date have often concluded that these groups are too young to have been influenced by these ancient continental movements. Here we examine a much larger and older angiosperm clade, the Campanulidae, and infer its biogeographic history by combining Bayesian divergence time information with a likelihood-based biogeographic model focused on the Gondwanan landmasses.

Results

Our analyses imply that campanulids likely originated in the middle Albian (~105 Ma), and that a substantial portion …

How Information Science Professionals Add Value In A Scientific Research Center, Chris Eaker, Andrea Thomer, Erica Johns, Kayla Siddell

DataONE Sociocultural and Usability & Assessment Working Groups

In response to the increasing need for a data curation workforce, the Data Curation Education in Research Centers program is educating library and information science students in scientific data curation. During the summer of 2012, the authors worked alongside scientists and data managers at the National Center for Atmospheric Research in Boulder, Colorado, to learn data curation within the context of a research center. Each student was matched with a “Science Mentor” and a “Data Mentor” based on prior work experience and the results of a placement questionnaire completed before the internship. Though NCAR has robust data services, we found …

Computer Code Verification And Cross Section Calculation For Promethium-147, Rita Inez Zell-Lusk

Nuclear Engineering Reports

The goals of this research are to (1) verify the predictions and accuracy of two computer codes which will be utilized in future research on Pm-147 production with data from a previous experiment and to (2) measure the cross section of Pm-147 for single neutron capture producing Pm-148 ground state and Pm-148 metastable state. The research in goal (1) used previous data obtained by James H. Hinderer in 2010 and a sample of Promethium-147 prepared by Rose Boll in 2006. The main elements of the new research done here included a correction of Mr. Hinderer’s data and the subsequent use …
