- Annotating and Identifying Emotions in Text
- This book chapter discusses annotating and identifying emotions in text. Abstract: This paper focuses on the classification of emotions and polarity in news headlines and it is meant as an exploration of the connection between emotions and lexical semantics. The authors first describe the construction of the data set used in evaluation exercise "Affective Text" task at SemEval 2007, annotated for six basic emotions: Anger, Disgust, Fear, Joy, Sadness, and Surprise, and for Positive and Negative polarity. The authors also briefly describe the participating systems and their results. Second, exploiting the same data set, the authors propose and evaluate several knowledge-based and corpus-based methods for the automatic identification of emotions in text. digital.library.unt.edu/ark:/67531/metadc31010/
- Annual Variation of Abundance and Composition in Forest Bird Assemblages on Navarino Island, Cape Horn Biosphere Reserve, Chile
- This article discusses the annual variation of abundance and composition in forest bird assemblages on Navarino Island, Cape Horn Biosphere Reserve, Chile. Abstract: The structure and dynamics of avian communities in the temperate forests of southern South America have been generally studied during the breeding season (November - March), and reports about seasonal variations and migratory behavior of species are almost lacking. This study examined intra-annual variations on a monthly basis in bird species composition and abundance in the world's southernmost forested ecosystems, found in the Cape Horn Biosphere Reserve, Chile (55°S). Combining data obtained through point-count surveys, mist-netting, and checklist methods, the authors recorded a total of 34 bird species belonging to 20 families. Eighteen of these species were Passeriformes, and the most abundant year-round resident species were Thorn-tailed Rayadito (Aphrastura spinicauda) and Patagonian Sierra-Finch (Phrygilus patagonicus). The most abundant seasonal migrants species were White-crested Elaenia (Elaenia albiceps) and Southern House Wren (Troglodytes musculus). Point-count and mist-netting methods showed a reduction in species richness and abundance during winter, with one third of the bird assemblage absent. This proportion was lower than that documented for more northern Nothofagus forests. Additionally, the authors' data provided no evidence that intra-annual patterns of avian community structure were significantly affected by a recently implemented tourism trail through the Omora Park. The authors believe that understanding seasonal patterns of richness, abundance, and migratory status of Chilean temperate forests birds will help to better understand the world's southernmost forest ecosystem, implement effective conservation, facilitate sustainable ecotourism, and lead to new ecological and evolutionary research. digital.library.unt.edu/ark:/67531/metadc97951/
- Anomalous diffusion and ballistic peaks: A quantum perspective
- This article discusses anomalous diffusion and ballistic peaks. Abstract: The quantum kicked rotor and the classical kicked rotor are both shown to have truncated Lévy distributions in momentum space, when the classical phase space has accelerator modes embedded in a chaotic sea. The survival probability for classical particles at the interface of an accelerator mode and the chaotic sea has an inverse power-law structure, whereas that for quantum particles has a periodically modulated inverse power law, with the period of oscillation being dependent on Planck's constant. These logarithmic oscillations are a renormalization group property that disappears as ħ → 0 in agreement with the correspondence principle. digital.library.unt.edu/ark:/67531/metadc75417/
- Anomalous diffusion and environment-induced quantum decoherence
- This article discusses anomalous diffusion and environment-induced quantum decoherence. Abstract: We study the anomalous diffusion resulting from the standard map in the so-called accelerating state, and we observe that it is determined by unusually large times of sojourn of the classical trajectories in the fractal region at the border between the chaotic sea and the acceleration island. The quantum-mechanical breakdown of this property implies a coherence among so slightly different values of momentum as to become much more robust against environment fluctuations than the quantum localization corresponding to normal diffusion. digital.library.unt.edu/ark:/67531/metadc139477/
- Anomalous diffusion associated with nonlinear fractional derivative Fokker-Planck-like equation: Exact time-dependent solutions
- This article discusses anomalous diffusion associated with nonlinear fractional derivative Fokker-Planck-like equation. Abstract: We consider the d=1 nonlinear Fokker-Planck-like equation with fractional derivatives (∂/∂t)P(x,t) = D(∂ƴ/∂xƴ)[P(x,t]v. Exact time-dependent solutions are found for v = (2 - y)/(1 + y)(-∞ < y ⩽ 2). By considering the long-distance asymptotic behavior of these solutions, a connection is established, namely, q = (y + 3)/(Y + 1)(0 < y ⩽ 2), with the solutions optimizing the nonextensive entropy characterized by index q. Interestingly enough, this relation coincides with the only already known for Lévy-like superdiffusion (i.e., v = 1 and 0 < y ⩽ 2). Finally, for (y,v) = (2,0) the authors obtain q=5/3, which differs from the value q = 2 corresponding to the y = 2 solutions available in the literature (v < 1 porous medium equation), thus exhibiting nonuniform convergence. digital.library.unt.edu/ark:/67531/metadc77162/

- Answering complex, list and context questions with LCC's Question-Answering Server
- Abstract: This paper presents the architecture of the Question-Answering server (QAS) developed at the Language Computer Corporation (LCC) and used in the TREC-10 evaluations. LCC's QAS™ extracts answers for (a) factual questions of variable degree of difficulty; (b) questions that expect lists of answers; and (c) questions posed in the context of previous questions and answers. One of the major novelties is the implementation of bridging inference mechanisms that guide the search for answers to complex questions. Additionally, LCC's QAS™ encodes an efficient way of modeling context via reference resolution. In TREC-10, this system generated an RAR of 0.58 on the main task and 0.78 on the context task. digital.library.unt.edu/ark:/67531/metadc83297/

- Appendix B: MetaArchive-SRB Transfer
- This is an appendix to the MetaArchive Final Report. This appendix document is a report on the status of a two-phase transfer test being carried out between the MetaArchive Cooperative and Chronopolis. These tests aim to demonstrate a proof-of-concept that the MetaArchive network may use Chronopolis's data grid preservation service as an exit strategy in the event that either MetaArchive or LOCKSS becomes unsustainable in the future. digital.library.unt.edu/ark:/67531/metadc109713/
- Appendix C: MetaArchive-iRODS Transfer Prep
- This is an appendix to the MetaArchive Final Report. This appendix document describes the preparation of archival units residing on a LOCKSS file system that have been designated for packaging and exchange with a non-LOCKSS-based preservation environment-in this case an iRODS grid-based environment. This process was tested with the University of North Texas (UNT) and Chronopolis (SDSC). Further development would be needed to integrate packaging mechanisms for use with other non-iRODS environments. The packaging process is accomplished using a combination of content serving features enabled through the LOCKSS software, a custom script ("lockssbagger") developed by UNT, and BagIt (CDL-LOC) as the primary exchange mechanism. The lockssbagger tool is detailed in Appendix B. digital.library.unt.edu/ark:/67531/metadc109714/
- Appendix D: LOCKSSBAGGER Tool
- This is an appendix to the MetaArchive Final Report. This appendix document describes tools. These tools are designed to facilitate the transfer of data contained within a number of LOCKSS archival units and packaged into bags. The bags are then transferred to the iRODS grid. The user has the option of creating and sending filled bags, or holey bags. The primary tools are written in Python, and make use of the iRODS command line utilities for data transfer. digital.library.unt.edu/ark:/67531/metadc109715/
- Appendix E: MetaArchive-iRODS Transfer
- This is an appendix to the MetaArchive Final Report. This appendix document describes an automation process that involved the sending of a Folger Shakespeare Library collection (246 archival units measuring 1.3TB) hosted on a University of North Texas (UNT) LOCKSS cache to a storage resource hosted by Chronopolis at the San Diego Supercomputer Center (SDSC). In order to transfer the content to the iRODS-based Chronopolis data grid, each archival unit needed to be extracted from the LOCKSS cache, and sent via use of the iRODS icommands client utilities. In addition, it was imperative to monitor the transfer at all possible points to detect corruption and make certain that the integrity of the data was maintained. Finally, for the purpose of benchmarking and information gathering, time-based statistics needed to be recorded for each stage of the transfer. These processes were managed by a set of Python-based scripts and utilities that are described in this document. digital.library.unt.edu/ark:/67531/metadc109716/

- The Application Of An Ergonomically Modified Keyboard To Reduce Piano-Related Pain
- This article discusses the application of an ergonomically modified keyboard to reduce piano-related pain. The key width for the modern piano was established about 130 years ago. Before then, the key widths varied and were typically narrower than the modern piano as shown in Figure 1. During these early years it would have been normal for pianists to play and compose on different sizes of keyboards. In fact, technically challenging pieces written between 1750 and 1850 were probably composed using pianos with narrower keys underscoring Sakai's rationale as to why many modern pianists struggle with difficult piano techniques on a modern piano.1 Since the distance of an octave span became fixed around 1880, pianists have been dealing with the idea of a one-size-fits-all piano and the disappearance of optional key widths for the piano. digital.library.unt.edu/ark:/67531/metadc84156/
- Application of the Correlation Consistent Composite Approach (ccCA) to Third-Row (Ga-Kr) Molecules
- This article discusses the application of the correlation consistent composite approach (ccCA). Abstract: The correlation consistent composite approach (ccCA) has been applied to the G3/05 training set of 51 energetic properties for the atoms and molecules that contain the 4p elements, Ga-Kr. When atomic and molecular first-order spin orbit coupling corrections are added to open shell atoms and molecules, the ccCA has a mean absolute deviation from experiment (MAD) of 0.95 kcal mol-1, an improvement of 0.10 kcal mol-1 over G3 and G3X model chemistries. The performance of the ccCA on third-row-containing atoms and molecules is, therefore, commensurate in accuracy with previous studies on lighter main group elements H-Ar. While the typical methods used to compute theoretical molecular spin orbit corrections may go against the spirit of "black box" model chemistries, such corrections may be necessary for molecules containing heavy elements such as Ga-Kr. For example, when second-order spin orbit corrections are added to the atomic and molecular energies, the ccCA MAD is reduced to 0.88 kcal mol-1. digital.library.unt.edu/ark:/67531/metadc75422/

- Applications of wireless sensors in monitoring Indoor Air Quality in the classroom environment
- This report discusses applications of wireless sensors in monitoring Indoor Air Quality in the classroom environment. Abstract: The focus of this research project was to investigate Indoor Air Quality monitoring technologies, government regulations and policies, and best practices to improve IAQ while minimizing the adverse effect of poor IAQ, specifically in the classroom environment. The investigation involved two parts: development of a cost effective indoor air quality prototype sensor unit and the deployment of the unit to monitor 5 different indoor locations. The data from the sample monitoring locations will then be compiled and analyzed. In addition, researching the literature was instrumental in establishing the parameters for testing the environment and conducting experiments. This provided valuable experiences which will be shared with both district teachers and students. digital.library.unt.edu/ark:/67531/metadc155621/

- Applying User-Centered Design Principles to Redesign the Interface to the Portal to Texas History: The IOGENE Project
- This paper discusses applying user-centered design principles to redesign The Portal to Texas History. Abstract: The IOGENE project at the University of North Texas Libraries applied user-centered design principles to redesign the interface to a unique digital library of cultural heritage materials, The Portal to Texas History. Since its launch in 2004, the interface had become dated and implementation of new functionality was constrained by the underlying technical infrastructure. Genealogists, a significant and under-studied class of digital library users, participated in the redesign of the Portal's interface. At the outset of the project, focus group discussions provided insights regarding genealogists' information needs as well as their research practices in relation to online information systems. In large part, these insights informed the functional requirements for the redesign of the Portal's user interface. Subsequent to each of two public releases of the redesigned interface, genealogists were engaged in usability testing. An online survey measured user satisfaction prior to and after the new interface was released. Results determined that satisfaction with the Portal significantly improved after the final release of the redesigned interface. The project's process and findings will be of interest to archives and digital libraries facing similar challenges in regard to redesigning their user interface and involving users in the design process. digital.library.unt.edu/ark:/67531/metadc28324/

- Approximating User Distributions in WCDMA Networks Using 2-D Gaussian
- This paper discusses approximating user distributions in WCDMA networks using 2-D Gaussian. Abstract: In this paper, we present an analytical model for approximating the user distributions in multi-cell third generation WCDMA networks using 2-dimensional Gaussian distributions by determining the means and the standard deviations of the distributions for every cell. This allows us to calculate the inter-cell interference and the reverse-link capacity of the network. The authors compare their model with simulation results and show that it is fast and accurate enough to be used efficiently in the planning process of large WCDMA networks. digital.library.unt.edu/ark:/67531/metadc30820/

- Archaeal Abundance In The Sargasso Sea
- This paper discusses research on archaeal abundance in the Sargasso Sea. Abstract: Archaea are a specific and separate domain of microbes with significant effects on the microbial community and nutrient cycles of the ocean. Archaea are commonly represented by two phyla, Crenarchaeota and Euryarchaeota. These microbes are found throughout the mesopelagic (200m-1000m) and bathypelagic (>1000m) areas in the Sargasso Sea. The archaea were collected on Bermuda Atlantic Time Series Validation cruises 45 and 46 to Puerto Rico. Archaea were enumerated using catalyzed reporter deposition fluorescence in situ hybridization (CARD-FISH). The results from BV 45 and BV 46 were lower than expected. Euryarchaeota averaged 3.6%±2.4% in the mesopelagic and averaged 5.9%±2.2% in the bathypelagic of the total DAPI count. Crenarchaeota averaged 3.7%±2.4% in the mesopelagic and averaged 5.1%±2.7% in the bathypelagic of the total DAPI count. digital.library.unt.edu/ark:/67531/metadc86187/

- Architecture Support for 3D Obfuscation
- This article discusses architecture support for 3D obfuscation. Abstract: Software obfuscation is defined as a transformation of a program P into T(P) such that the whitebox and blackbox behaviors of T(P) are computationally indistinguishable. However, robust obfuscation is impossible to achieve with the existing software only solutions. This results from the power of the adversary model in DRM which is significantly more than in the traditional security scenarios. The adversary has complete control of the computing node - supervisory privileges along with the full physical as well as architectural object observational capabilities. In essence, this makes the operating system (or any other layer around the architecture) untrustworthy. Thus the trust has to be provided by the underlying architecture. In this paper, the authors develop an architecture to support 3-D obfuscation through the use of well known cryptographic methods. The three dimensional obfuscation hides the address sequencing, the contents associated with an address, and the temporal reuse of address sequences such as in loops (or the second order address sequencing). The software is kept as an obfuscated file system image statically. Moreover, its execution traces are also dynamically obfuscated along all the three dimensions of address sequencing, contents and second order address sequencing. Such an obfuscation makes it infinitesimally likely that good tampering points can be detected. This in turn provides with a very good degree of tamper resistance. With the use of already known software distribution model of ABYSS and XOM, the authors can also ensure copy protection. This results in a complete DRM architecture to provide both copy protection and IP protection. digital.library.unt.edu/ark:/67531/metadc132973/

- Archiving Web-Published Materials: A Needs Assessment of Librarians, Researchers, and Content Providers
- This article discusses archiving web-published materials. Abstract: The Web-at-Risk project is a digital preservation project funded by the Library of Congress as part of the National Digital Information Infrastructure and Preservation Program. The project is developing a web archiving service to enable curators to build, store, and manage archived collections of web-published materials captured largely from US federal and state government agency web sites. In 2005 the project‟s 22 curators, as well as librarians and archivists working primarily in academic libraries (N=43), university researchers (N=7), and content providers (N=7) participated in a study to identify their needs in relation to web archiving. This paper summarizes the issues and challenges these groups face and discusses the need for collaborations among libraries and government entities for preserving web-published materials. digital.library.unt.edu/ark:/67531/metadc29322/
- Are Net Discount Rates Stationary?: Some Further Evidence
- This article discusses net discount rates. Abstract: Gamber and Sorensen provide evidence suggesting that the net discount ratio experienced a level shift in the mean between 1977 and 1981. If such a shift occurred, the nonlinearity in the data shows up as a failure to reject the null hypothesis that a unit root is present; that is, the series is I(1). In this reply, evidence is presented - the Phillips-Perron test and a univariate version of the Stock-Watson q-test - suggesting that the net discount ratio is stationary. Hence, the mean is constant. In addition, if one extends the analysis to include the 1989 through 1993 period, the net discount ratio appears to be reverting. digital.library.unt.edu/ark:/67531/metadc71791/
- Are Net Discount Ratios Stationary?: The Implications For Present Value Calculations
- Abstract: This article analyzes the relationship between real interest rates and real growth rates in wages. The stationary of these time series has been discussed in the literature. However, since the net discount ratio, (1 + gτ)/(1 + rτ), is a nonlinear transformation, it is not necessarily stationary even if the interest rate and growth rate in wages series are each stationary. On the other hand, the net discount ratio may be stationary even if the interest rate and growth rate series are both non-stationary. The significant finding of this article is that this ratio is stationary. This conclusion appears robust since it holds for at least four different Treasury securities analyzed: three month, six month, one year, and three year. Therefore, a real net discount ratio, (1 + gτ)/(1 + rτ), can be used with confidence in constructing present value forecasts of expected earnings. digital.library.unt.edu/ark:/67531/metadc71790/

- Aromatic C-H Activation and Catalytic Hydrophenylation of Ethylene by TpRu{P(OCH2)3CEt} (NCMe)Ph
- This article discusses aromatic C-H activation and catalytic hydrophenylation of ethylene by TpRu{P(OCH2)3CEt} (NCMe)Ph. Abstract: The complexes TpRu{P(OCH2)3CEt}(L)R {L = PPh3 or NCMe; R = Cl, OTf (OTf = trifluoromethane-sulfonate), or Ph; Tp = hydridotris(pyrazolyl)borate} and TpRu{P(OCH2)3CEt} (ɳ3-C3H4Me) were synthesized and isolated. TpRu{P(OCH2)3CEt} (NCMe)Ph was found to initiate C-H activation of benzene and to catalyze the hydrophenylation of ethylene to produce ethylbenzene. Ethylene C-H activation to ultimately produce TpRu{P(OCH2)3CEt} (ɳ3-C3H4Me) kinetically competes with the catalytic hydrophenylation of ethylene. Computational studies were undertaken on reactions in the proposed catalytic ethylene hydrophenylation cycle as well as key side reactions. digital.library.unt.edu/ark:/67531/metadc77190/
