Knowledge Representation and Subject Access in Electronic Theses and Dissertations: Analysis of Creators’ and Users’ Assumptions and Expectations
This paper analyzes the relationship between subject terms -- both authorized terms from controlled vocabularies and free-text keywords -- used to succinctly describe the content of the electronic theses and dissertations (ETDs) and the search terms entered by users to discover and access the ETDs. Identification of search terms and comparison of search results with subject terms used in describing ETDs provides a basis for assessing the relative usefulness of controlled-vocabulary subject terms supplied by professional indexers and free-text keywords supplied by authors of ETDs in facilitating access to ETDs. Arguably, there has been a shift in the way users search, access, and use information resources.

Representation of Recorded Knowledge and Extended Date/Time Format: A Case Study of the Digital Public Library of America
This presentation presents results of a study that analyzed representation of dates and time in one of the largest aggregators of digital content in the world -- the Digital Public Library of America (DPLA). The findings demonstrate both similarities and differences in date and time representation across DPLA content hub and service hub provider groups.

Service learning in action: Integrating reflection to deepen the educational experience
This article focuses on service learning projects (SLPs) sponsored by the University of North Texas College of Information. A constructivist learning environment perspective was applied to the potential for library science international service learning projects to provide a short term learning environment that introduces pedagogy, provides the opportunity to develop and apply new skills, energizes students to develop cultural competence, and develops reflective skills towards the pursuit of wisdom.

Giant cross-magnetic-field steps due to binary collisions between pair particles
Article explores giant cross-magnetic-field steps which occur as a result of positron-electron collisions. Within a constant magnetic field (e.g., 1 T), a collision between a positron and an electron can result in a correlated drift across the magnetic field for a continuous range of impact parameters. Within this range, drift distances orders of magnitude larger than that associated with like-charge collisions were observed by computer simulation.

RNA helicase DP103 and TAK1: a new connection in cancer
Article on new markers of tumor metastasis. The authors found that expression of DP103 was significantly upregulated in the metastatic basal subtype of breast cancers in 3 independent cohorts. This elevated DP103 expression correlated with metastatic breast cancer gene signatures and was strongly associated with patient survival. This study provides the first evidence that the RNA helicase DEAD-box protein DP103 is an NF-kB target that could form part of a positive feedback loop contributing to DP103- mediated regulation of TAK1 kinase activity on the major NF-kB kinase IKK2, thus implicating DP103 in the maintenance of this oncogenic signaling arm in human cancer.

Unveiling the Co-Word Structures Among Mobile Computing, Mobile Commerce and Mobile Application Research: A Science Mapping Analysis
Article on the interplay over time among mobile computing, commerce and applications. The study performed is a co-word analysis for a corpus of 4821 SCI/SSCI indexed papers related to mobility in the Web of Science (WoS) database from 1995 to 2013. The emerging concepts demonstrated in the strategic diagrams and the associated co-word structures have implications for future research.

Loitering at the hilltop on exterior domains
In this article, the author proves the existence of an infinite number of radial solutions of Δu+f(u)=0 on the exterior of the ball of radius R>0 centered at the origin and f is odd with f<0 on (0,β), f>0 on (β,δ), and f≡0 for u>δ. The primitive F(u)=∫u0f(t)dt has a "hilltop" at u=δ which allows one to use the shooting method and ODE techniques to prove the existence of solutions.

Tribological Properties of (EN AW-AlCu4MgSi(A)) Aluminium Alloy Surface Layer After Ball Burnishing
Article presents the tribological properties of (EN AW-AlCu4MgSi(A)) aluminium alloy surface layer after ball burnishing. EN AW-AlCu4MgSi(A) aluminium alloy is widely used as a structural material in aerospace and automotive applications. The authors have subjected it to grinding, polishing and ball burnishing. The authors have performed ball-on-disk tribological tests. We have also determined normalized 3D roughness parameters. High surface smoothness turns out to be obtainable. Favorable effect of the ball burnishing on the tribological properties of the alloy are seen. Results will be presented at the International Scientific Conference BALTTRIB, 2015.

Using a Partial Sum Method and GPS Tracking Data to Identify Area Restricted Search by Artisanal Fishers at Moored Fish Aggregating Devices in the Commonwealth of Dominica
This article explores research to identify area-restricted search foraging behavior at fish aggregating device (FAD) patches. Movement data were collected from GPS devices placed on foraging trips originating in the artisanal fishing village of Desa Ikan (pseudonym), on the east coast of the Caribbean island nation of the Commonwealth Dominica. The goal of the research is to understand how property rights are emerging after the introduction of fish aggregating device (FAD) technology at the site in 1999.

Understanding Melanocyte Stem Cells for Disease Modeling and Regenerative Medicine Applications
This review highlights recent studies and progress involved in understanding the development of cutaneous melanocytes and the regulation of McSCs. Melanocytes in the skin play an indispensable role in the pigmentation of skin and its appendages. It is well known that the embryonic origin of melanocytes is neural crest cells. In adult skin, functional melanocytes are continuously repopulated by the differentiation of melanocyte stem cells (McSCs) residing in the epidermis of the skin.
