description: A classical nova is an eruption on the surface of a white dwarf in an accreting binary system. The material ejected from the white dwarf surface generally forms an axisymmetric shell. The shaping mechanisms of nova shells are probes of the processes that take place at energy scales between planetary nebulae and supernova remnants. We report on the discovery of nova shells surrounding the post-nova systems V4362 Sagittarii (1994) and more limited observations of DO Aquilae (1925). Distance measurements of 0.5p/m1.4 kpc for V4362 Sgr and 6.7 p/m 3.5 kpc -0.2 for DO Aql are found based on the expansion parallax method. The growth rates are measured to be 0.07``/year for DO Aql and 0.32``/year for V4362 Sgr. A preliminary investigation into the ionisation structure of the nova shell associated with V4362 Sgr is presented. The observed ionisation structure of nova shells depends strongly on their morphology and the orientation of the central component towards the observer. X-ray, IR and UV observations as well as optical integral field unit spectroscopy are required to better understand these interesting objects.

description: We present results of 2D and 3D PIC simulations of magnetic turbulence production by isotropic cosmic-ray ions drifting upstream of SNR shocks. The studies aim at testing recent predictions of a strong amplification of short wavelength magnetic field and at studying the evolution of the magnetic turbulence and its backreaction on cosmic rays. We observe that an oblique filamentary mode grows more rapidly than the non-resonant parallel modes found in analytical theory, and the growth rate of the field perturbations is much slower than is estimated for the parallel plane-wave mode, possibly because in our simulations we cannot maintain omega << Omega_i, the ion gyrofrequency, to the degree required for the plane-wave mode to emerge. The evolved oblique filamentary mode was also observed in MHD simulations to dominate in the nonlinear phase. We thus confirm the generation of the turbulent magnetic field due to the drift of cosmic-ray ions in the upstream plasma, but as our main result find that the amplitude of the turbulence saturates at about dB/B~1. The backreaction of the turbulence on the particles leads to an alignment of the bulk-flow velocities of the cosmic rays and the background medium, which is an essential characteristic of cosmic-ray modified shocks. It accounts for the saturation of the instability at moderate field amplitudes. Previously published MHD simulations have assumed a constant cosmic-ray current and no energy or momentum flux in the cosmic rays, which excludes a backreaction of the generated magnetic field on cosmic rays, and thus the saturation of the field amplitude is artificially suppressed. This may explain the continued growth of the magnetic field in the MHD simulations. A strong magnetic field amplification to amplitudes dB >> B0 has not been demonstrated yet.

description: The motion of glaciers over their bedrock or drops of fluid along a solid surface can vary dramatically when these substrates are lubricated. We investigate the coupled flow of a gravity current (GC) of strain-rate softening fluid that is lubricated by a denser, lower-viscosity Newtonian fluid. We present a set of experiments in which such GCs are discharged axisymmetrically and at constant flux over a flat surface. Using imaging techniques we follow the front evolution of each fluid and their thickness field. We find that the two fronts of our lubricated GCs evolve faster than non-lubricated GCs, though with similar time exponents. In addition, the thickness of the non-Newtonian fluid is nearly uniform while that of the lubricating fluid is nonmonotonic with localised spikes. Nevertheless, lubricated GCs remain axisymmetric as long as the flux of the lubricating fluid is sufficiently smaller than the non-Newtonian fluid flux.

description: Research suggests that the duration of a VR session modulates the presence and intensity of VRISE, but there are no suggestions regarding the appropriate maximum duration of VR sessions. The implementation of high-end VR HMDs in conjunction with ergonomic VR software seems to mitigate the presence of VRISE substantially. However, a brief tool does not currently exist to appraise and report both the quality of software features and VRISE intensity quantitatively. The VRNQ was developed to assess the quality of VR software in terms of user experience, game mechanics, in-game assistance, and VRISE. Forty participants aged between 28 and 43 years were recruited (18 gamers and 22 non-gamers) for the study. They participated in 3 different VR sessions until they felt weary or discomfort and subsequently filled in the VRNQ. Our results demonstrated that VRNQ is a valid tool for assessing VR software as it has good convergent, discriminant, and construct validity. The maximum duration of VR sessions should be between 55-70 minutes when the VR software meets or exceeds the parsimonious cut-offs of the VRNQ and the users are familiarized with the VR system. Also. the gaming experience does not seem to affect how long VR sessions should last. Also, while the quality of VR software substantially modulates the maximum duration of VR sessions, age and education do not. Finally, deeper immersion, better quality of graphics and sound, and more helpful in-game instructions and prompts were found to reduce VRISE intensity. The VRNQ facilitates the brief assessment and reporting of the quality of VR software features and/or the intensity of VRISE, while its minimum and parsimonious cut-offs may appraise the suitability of VR software. The findings of this study contribute to the establishment of rigorous VR methods that are crucial for the viability of immersive VR as a research and clinical tool.

description: We have carried out a sensitive search for gas emission lines at infrared and millimeter wavelengths for a sample of 15 young sun-like stars selected from our dust disk survey with the Spitzer Space Telescope. We have used mid-infrared lines to trace the warm (300-100 K) gas in the inner disk and millimeter transitions of 12CO to probe the cold (~20 K) outer disk. We report no gas line detections from our sample. Line flux upper limits are first converted to warm and cold gas mass limits using simple approximations allowing a direct comparison with values from the literature. We also present results from more sophisticated models following Gorti and Hollenbach (2004) which confirm and extend our simple analysis. These models show that the SI line at 25.23 micron can set constraining limits on the gas surface density at the disk inner radius and traces disk regions up to a few AU. We find that none of the 15 systems have more than 0.04 MJ of gas within a few AU from the disk inner radius for disk radii from 1 AU up to ~40 AU. These gas mass upper limits even in the 8 systems younger than ~30 Myr suggest that most of the gas is dispersed early. The gas mass upper limits in the 10-40 AU region, that is mainly traced by our CO data, are <2 Mearth. If these systems are analogs of the Solar System, either they have already formed Uranus- and Neptune-like planets or they will not form them beyond 100 Myr. Finally, the gas surface density upper limits at 1 AU are smaller than 0.01% of the minimum mass solar nebula for most of the sources. If terrestrial planets form frequently and their orbits are circularized by gas, then circularization occurs early.

description: Frequently, the serum concentrations of TSH (s-TSH) and free thyroxine (s-FT4) are interpreted together when a physician considers the patient’s thyroid status. Then, each measurement is compared with its univariate reference interval. However, a pair of s-TSH and s-FT4 may be more appropriately assessed if compared with a bivariate reference interval. We constructed a bivariate reference interval for s-TSH and s-FT4 from their measurements in 495 healthy blood donors. After Box-Cox transformation, we estimated the Mahalanobis distances from each pair of s-TSH and s-FT4 to the center of the bivariate distribution. The 95 percentile in the distribution of the Mahalanobis distances was defined as the limit of the bivariate reference interval. Univariate reference intervals comprising the central 95% (2.5–97.5 percentile) and 97.5% (1.25–98.75 percentile) of reference values were estimated from the same data. Normal thyroid function was defined as both s-TSH and s-FT4 within their respective univariate reference intervals, or as a Mahalanobis distance within the 95% bivariate reference interval. In 177,514 specimens from adult individuals in out-patient care, 76.6% were classified as bivariate normal. The corresponding figures for the 95% and 97.5% univariate reference intervals were 68.9% and 76.2%, respectively. The kappa statistics for classification agreement between the bivariate 95% reference interval and the 95% and 97.5% univariate reference intervals were 0.790 and 0.881, respectively. We thought the bivariate reference interval to be clinically most accurate but were unable to prove it.
Antibody-catalyzed formation of a 14-membered ring lactone

description: A number of macrolide antibiotics have a 14-membered ring lactone skeleton. Besides the stereochemical challenges associated with the syntheses of these macrocyclic compounds, the difficulty in controlling the ring forming step has provided the basis for many synthetic organic methodology studies. Attempts to use enzymes in aqueous and organic solvents to catalyze medium to large ring lactonizations has met with limited success, particularly with secondary alcohols. We report monoclonal antibody F123, raised against transition state analogue 50, which catalyzed the intramolecular transesterification of hydroxyester 57 to give the 14-membered ring lactone 19. The reaction of antibody F123 with substrate 57 displayed enzyme-like [Chemical model] Michaelis-Menten kinetics. The kinetic parameters of this antibody reaction were determined by two methods, namely a multiwell method and the spectrophotometric cuvette method. Analysis of the reaction of F123 with 57 via the multiwell method yielded a Km of 250 ± 10 uM, Vmax of 0.62 ± 0.01 ixmol/min mg and a kcat of 1.1 min"1. The spectrophotometric cuvette method yielded a rCr, of 330 ± 50 uM, V m a x of 1.4 ± 0.1 umol/min mg and a kcat of 2.2 min'1. The results obtained from these two methods were found to be in good agreement once the delay times in determining initial rates, characteristic of the multiwell method, were accounted for. In both methods, the observed rates were [chemical model] corrected for the background hydrolysis in buffer. Substrate specificity and competitive inhibition by the hapten derivative 60 (K = 2.9 ± 0.4 u.M) demonstrated that the catalytic activity was associated with binding in the antibody-combining site. Finally, the lactone product was isolated from pooled antibody-catalyzed reactions by ether extraction and identified using gas chromatography-mass spectroscopy by comparison with an authentic lactone sample.

description: The quick detection and localization of partial discharge (PD) in an air-insulated substation (AIS) based on ultrahigh-frequency (UHF) sensor arrays are efficient for power equipment monitoring. The adopted UHF PD time difference of arrival (TDOA) methods mainly use the time difference of electromagnetic wave signals. Thus, the system requires both a high sampling rate and time synchronization accuracy, leading to a high cost and large size. In this study, the feasibility and accuracy of PD DOA in an AIS were investigated using a UHF wireless sensor array and the received signal strength indicator. First, the power pattern of the designed UHF wireless sensor array was obtained via an offline experiment. Then, a statistical approach to the PD DOA method based on the maximum likelihood estimator was employed to obtain the preliminary DOA result. Finally, interpolation and clustering algorithms were used to improve the accuracy of the DOA. A laboratory test was conducted. The average error of the PD DOA was less than 6°, and the cost-effectiveness and portability were clearly improved.

description: Process models are often the basis for demonstrating improvement and compliance in software engineering organizations. A descriptive model is a type of process model describing the human activities in software development that actually occur. The purpose of a descriptive model is to provide a documented baseline for further process improvement analysis. Organizations may hire experts or train employees to create a descriptive model but the costs are often exorbitant. As a result, some companies skip steps necessary for ensuring that employees are equipped to deal with the challenges of creating a descriptive model. Unfortunately, a descriptive model created by inexperienced practitioners usually does not contain information necessary for informed decision making. Ideally, a descriptive model provides an explicit representation of human centric software processes. However, if the model does not represent how a process is actually performed, subsequent recommendations for improvement may be based upon activities that are depicted in the model but that do not actually take place. Similarly, a descriptive model may omit important features and characteristics that are centrally relevant for an organization's process improvement goals. The accuracy of software process elicitation is an important topic for study given this context. Accuracy, is the degree to which a descriptive model reflects the actual process. Prior studies address accuracy from the perspective of an expert working with a group of process performers. However, given the problems in practice, it is surprising that there is no identified research studying accuracy from the perspective of the user. This dissertation provides a synthesis of arguments from related literature that inform a research approach for studying accuracy from the perspective of the user creating a descriptive model. A series of experiments are conducted with test subjects in professional training settings. Hypothesis testing reveals that subjects who use a conceptual model to articulate process knowledge perceive more error between description and performance then those who do not. The results also suggest that written text can be captured to provide insight into a new important property of a process model, Coherence.

description: Uncontrollable costs, schedule overruns, and poor end product quality continue to plague the software engineering field. Innovations formulated with the expectation to minimize or eliminate cost, schedule, and quality problems have generally fallen into one of three categories: programming paradigms, software tools, and software process improvements. It is this last category of software process improvement (SPI) that is the concern of this research. Specifically, this research investigates SPI through the application of knowledge management (KM) at the software project level. KM is a technique that is used in many business domains as a means to capture, use, and build upon corporate knowledge assets. It can be viewed as complementary to SPI when used in a software development domain. This research advances the use of KM in SPI by investigating the use and flow of knowledge from the present in the present. In particular, it examines the flow of knowledge within an individual software development project as it executes, looking for impediments to that flow. The implicit hypothesis within this approach is that the removal of obstacles to project-level knowledge flow (K-flow) will enhance SPI. In particular, this research provides support for the application of KM at the individual project level for SPI, location and mitigation or removal of project-level K-flow obstacles for SPI, necessity for management of both explicit and tacit project-level knowledge, significance of the role of software engineers in project-level KM efforts, and and value of a facilitation role in project-level KM. The methodology used for this research was that of an exploratory case study of an industrial software development project. Data concerning project knowledge sources, sinks, flows, and context was gathered from professional software engineers and managers using semi-structured interviews. Using this data, a diagnostic project knowledge map (K-map) was constructed. The K-map was analyzed within a focus group of project software engineers for K-flow obstacles and potential solutions. Using these obstacles and solutions, questionnaires were formulated to probe software engineers' perceptions of the effect, if any, of the K-flow obstacle solutions on SPI. Findings reveal that software engineers perceive that the removal or mitigation of project-level K-flow obstacles generally reduces the time that it takes them to do their work, helps them to meet their deadlines, and improves their work quality, thus resulting in SPI.

description: The vibrational quenching cross sections and corresponding low-temperature rate constants for the v = 1 and v = 2 states of CN- colliding with He and Ar atoms have been computed ab initio using new three dimensional potential energy surfaces. Little work has so far been carried out on low-energy vibrationally inelastic collisions for anions with neutral atoms. The cross sections and rates calculated at energies and temperatures relevant for both ion traps and astrochemical modelling, are found by the present calculations to be even smaller than those of the similar C2- /He and C2-/Ar systems which are in turn of the order of those existing for the collisions involving neutral diatom-atom systems. The implications of our finding in the present case rather small computed rate constants are discussed for their possible role in the dynamics of molecular cooling and in the evolution of astrochemical modelling networks.

description: Saliva samples offer the possibility to obtain stress-free non-invasive samples, also for home-testing, especially useful when blood collection is either undesirable or difficult. The aim of this work was to develop an LC-MS/MS method to determine clinically relevant steroid hormones cortisol, cortisone, 11-deoxycortisol, 21-deoxycortisol, 17OH-progesterone, aldosterone, corticosterone, deoxycorticosterone, testosterone, androstenedione, DHEAS, DHEA, 17OH-pregnenolone, betamethasone and dexamethasone. A special effort was made to adapt the method to neonatal population with respect to choice of saliva as matrix, low sample volumes, selection of analytes and multiplexing. Validation included selectivity, interferences, matrix effects, lower and upper limit of quantification, linearity of calibration, dilution of samples, trueness, within-run and total analytical repeatability, robustness, carry-over, stability and recovery from sample collection swab. Ten microliters were acceptable but 50 µL preferable sample volume, except for 21-deoxycortisol. Cortisol, cortisone, aldosterone, 11-deoxycortisol, deoxycorticosterone, dexamethasone, betamethasone, 17OH-pregnenolone and DHEAS could be determined in as little as 2-5µL saliva. Total analytical variation was <15%, except for 17OH-progesterone, deoxycorticosterone, 17OH-pregnenolone, 21-deoxycortisol, androstenedione, DHEA and betamethasone, that could only be determined semi-quantitatively or qualitatively. The minimum turnaround time was 3–4 h. Recovery from the best performing sample collection swab SalivaBio ranged from 83 to 127%. Aldosterone, cortisone and DHEA were more stable in saliva compared to serum when stored at ambient temperature for one week. Corticosterone and 17OH-progesterone needed immediate freezing. The non-invasiveness, small saliva volume requirement, on-swab stability and analytical performance make the method relevant for both research and diagnostics, above all in the setting of neonatal intensive care unit.

description: We consider heavy sterile neutrinos $ν_s$, with mass in the range 10 MeV $\lesssim m_s \lesssim m_π \sim 135$ MeV, thermally produced in the early universe and freezing out after the QCD phase transition. The existence of these neutrinos may alter the value of the effective number of neutrino species $N_{\rm eff}$, measured by the cosmic microwave background (CMB), and the ${}^4$He production during the BBN. We provide a detailed account of the solution of the relevant Boltzmann equations and we identify the parameter space constrained by current Planck satellite data and forecast the parameter space probed by future Stage-4 ground-based CMB (CMB-S4) observations.

Informal Notes
Recognition-Based Text Entry
Mobile Device
Recognition Error
Graffiti 2

description: Mobile information technologies are theoretically well suited to digitally accommodate the informal note taking task wherewith the notes often recorded quickly and under less than ideal circumstances. Unfortunately, user adoption of mobile support for informal note taking has been hindered in large part by slow text entry techniques. Building on research confirming people's ability to read erroneous text and effectively use incomplete external retrieval cues, this dissertation investigated the effects of two modifications to Graffiti-based text entry with the goal of overcoming the barriers associated with current text entry solutions: disabling text correction and disabling visual feedback. As expected, both modifications improved text entry speed but also resulted in more errors in the resulting text which hindered the users' ability to recognize the words they had recorded. To address this decrease in recognizability, a multi-approach note enhancement mechanism was introduced. When this algorithm was applied to a set of particularly challenging erroneous notes, study participants were able to correctly recognize 56% more of the words in the notes. In a formal evaluation study with 75 participants, the proposed approach of discouraging user-initiated error correction during note taking, enhancing the resulting erroneous notes, and facilitating recall with enhanced alternative lists, was confirmed to increase the note taking speed by 47% without any negative impact on the participants' ability to recall important details about the scenarios which prompted the note taking activities. This research highlighted the importance of shifting the focus from accuracy to recallability when examining the overall efficacy of informal notes. With some easily implemented modifications to existing text entry techniques, combined with a note enhancement algorithm which leverages information about the errors users make and the types of errors users are more likely to overcome, a significant improvement in user performance was achieved. These results have important implications for how mobile technologies are designed to support both informal note taking and text entry in general.

Pervasive Computing Environments

description: The reality of pervasive computing has nearly been realized, if it has not already. Pervasive computing environments promise ubiquitous connectivity, a plethora of information, and seamless computing support. Despite the advances in infrastructure to deliver on Weiser's original vision for pervasive computing environments, little attention has been specifically given to decision support systems that are expected to operate in these environments. Issues such as large amounts of highly variant data and decision resource availability can directly influence decision support systems and subsequently limit the efficacy of the support they provide. Moreover, these factors can have a direct effect on decision outcomes for deterministic structured and semi-structured problems. This research investigates the impact of data utility enhancement and availability awareness on decision making and decision support systems. A decision support system architecture that addresses the limitations caused by the large amounts of variant data and uneven conditioning of connectivity that are characteristic in pervasive computing environments is proposed and developed. By incorporating data utility enhancement, availability awareness, and an agent-based framework, the decision support system architecture seeks to extend the breadth of decision support systems research. This architecture, which we call the Pervasive Agent Decision Support System (PADSS), integrates intelligent agents, wavelets, and instant messaging as a comprehensive decision support solution to address data utility and resource availability related issues in pervasive computing environments. As such, this research study combines several experiments that include qualitative evaluation, empirical evaluation, mathematical modeling, and simulation in a design science context. The culmination of the research concludes with an implementation and evaluation of a pervasive computing DSS based on the presented DSS architecture.

description: Privacy has always been a great concern of patients and medical service providers. As a result of the recent advances in Information Technology and the government's push for Electronic Health Record (EHR) systems, a large amount of data is collected and stored electronically. This data is an important and rich source for research and needs to be made available for mining, while at the same time patient privacy needs to be preserved. The management of medical data is heavily regulated by the Health Insurance Portability and Accountability Act (HIPAA) in the United States. This strong level of oversight and inherent characteristics of medical data make Privacy Preserving Medical Data Mining a special field of Privacy Preserving Data Mining (PPDM). Yet, research is quite limited in this field. This study pinpoints the following gaps in current research: 1. Privacy protection in the medical field means the protection of individuals from being associated with undesirable conditions, diagnoses or treatments (Sensitive Attributes). Most existing research only considers datasets with a single sensitive attribute, while most medical datasets contain multiple sensitive attributes (e.g., site, stage and histology of cancer). As a result, some well known privacy protection models such as L-diversity cannot be directly applied to such datasets. 2. Although medical researchers often describe their research plans when they request anonymized data, most existing PPDM methods do not use this information when de-identifying the data. As a result, the anonymized data may not be very useful for the planned mining task. This study investigates utility-based privacy protection techniques to address this problem. Our goal is to improve the utility of the anonymized data for statistical analyses that are frequently used in medical research, such as linear and logistic regression, proportional hazards model and classification. Our technique improves a popular privacy protection method called condensation such that the improved method will lead to de-identified datasets with more utility while the privacy in the transformed data is preserved. Our methods are tested and validated on real cancer surveillance data provided by the Kentucky Cancer Registry.

description: The accurate prediction of the solar Diffuse Fraction (DF), sometimes called the Diffuse Ratio, is an important topic for solar energy research. In the present study, the current state of Diffuse Irradiance research is discussed and then three robust, Machine Learning (ML) models, are examined using a large dataset (almost 8 years) of hourly readings from Almeria, Spain. The ML models used herein, are a hybrid Adaptive Network-based Fuzzy Inference System (ANFIS), a single Multi-Layer Perceptron (MLP) and a hybrid Multi-Layer Perceptron-Grey Wolf Optimizer (MLP-GWO). These models were evaluated for their predictive precision, using various Solar and Diffuse Fraction (DF) irradiance data, from Spain. The results were then evaluated using two frequently used evaluation criteria, the Mean Absolute Error (MAE) and the Root Mean Square Error (RMSE). The results showed that the MLP-GWO model, followed by the ANFIS model, provided a higher performance, in both the training and the testing procedures.

description: We present a 8 deg x 6 deg, high resolution extinction map of the Pipe nebula using 4.5 million stars from the Two Micron All Sky Survey (2MASS) point source catalog. The use of NICER, a robust and optimal technique to map the dust column density, allows us to detect a Av = 0.5 mag extinction at a 3-sigma level with a 1 arcmin resolution. We find for the Pipe nebula a normal reddening law, E(J-H) = (1.85 +/- 0.15) E(H-K). We measure the cloud distance using Hipparchos and Tycho parallaxes, and obtain ~130 pc. This, together with the total estimated mass, 10^4 Msun, makes the Pipe the closest massive cloud complex to Earth. We compare the NICER extinction map to the NANTEN 12CO observations and derive with unprecedented accuracy the relationship between the near-infrared extinction and the 12CO column density and hence (indirectly) the 12CO X-factor, that we estimate to be 2.91 10^20 cm^-2 K^-1 km^-1 s in the range Av

description: More and more adults and children communicate in online communities today. When communicating, people need to learn about each other's identity to understand and contextualize the communicative messages. In children's online communities, it is very important to allow them to safely explore their own or learn about the identities of others. The goals of this research were to describe the online identity content important to children - what they wanted to share and learn about each other, the identity similarities and differences that they noticed, and to inform the design of international children's communities to support children's online identity. To meet the research goals, this research utilized qualitative methods, including the ethnographic approach. I worked with 27 children between the ages of 7-10 from Hungary, Mexico, and the United States and studied their self-representations on paper, through digital photos, personal video messages, and online using an international children's online community prototype. I conducted observations and interviews, administered several questionnaires, and audio- and video-recorded children's interaction with the prototype. The research discovered several important findings concerning children's online identity. All participants revealed their true and complete identities online. They focused on sharing and learning about personal, ethnic, and gender identities but ignored the cultural identity. The identity aspects that were the most important to them were the information on themselves, families, homes, schools, friends, and pets. Though all these aspects were represented in the various media types that we provided, the affordance of each media type facilitates the representation of different aspects of their identity, which indicated the importance of multi-media online identity support for children. For example, children described their hobbies across all the media, but they preferred drawing their portraits and pets, showing photos of their homes and family members, and discussing personal and school-related topics on video. Through the online interaction, children identified many similarities and differences. They formed good opinions of each other because of the similarities, while the differences did not prevent them from becoming friends. Based on these findings, I made design recommendations for the international children's online communities to support children's online identity and communication.
