description: Spin transport experiments in graphene, a single layer of carbon atoms, indicate spin relaxation times that are significantly shorter than the theoretical predictions. We investigate experimentally whether these short spin relaxation times are due to extrinsic factors, such as spin relaxation caused by low impedance contacts, enhanced spin flip processes at the device edges or the presence of an aluminium oxide layer on top of graphene in some samples. Lateral spin valve devices using a field effect transistor geometry allowed for the investigation of the spin relaxation as a function of the charge density, going continuously from metallic hole to electron conduction (charge densities of $n\sim 10^{12}$cm$^{-2}$) via the Dirac charge neutrality point ($n \sim 0$). The results are quantitatively described by a one dimensional spin diffusion model where the spin relaxation via the contacts is taken into account. Spin valve experiments for various injector/detector separations and spin precession experiments reveal that the longitudinal (T$_1$) and the transversal (T$_2$) relaxation times are similar. The anisotropy of the spin relaxation times $τ_\parallel$ and $τ_\perp$, when the spins are injected parallel or perpendicular to the graphene plane, indicates that the effective spin orbit fields do not lie exclusively in the two dimensional graphene plane. Furthermore, the proportionality between the spin relaxation time and the momentum relaxation time indicates that the spin relaxation mechanism is of the Elliott-Yafet type. For carrier mobilities of 2-5$\times 10^3$ cm$2^$/Vs and for graphene flakes of 0.1-2 $μ$m in width, we found spin relaxation times of the order of 50-200 ps, times which appear not to be determined by the extrinsic factors mentioned above.

description: The journal set which provides a representation of nanoscience and nanotechnology at the interfaces among applied physics, chemistry, and the life sciences is developing rapidly because of the introduction of new journals. The relevant contributions of nations can be expected to change according to the representations of the relevant interfaces among journal sets. In the 2005 set the position of the USA decreased more than in the 2004-set, while the EU-27 gained in terms of its percentage of world share of citations. The tag "Y01N" which was newly added to the EU classification system for patents, allows for the visualization of national profiles of nanotechnology in terms of relevant patents and patent classes.

title: Regulation and Expression of Nanog, Oct4, and Sox2 in the Bovine Blastocyst following Somatic Cell Nuclear Transfer
Creators: name: Hall, Justin Scott
Publisher: name: Utah State University
Year: 2013

description: A live birth from a somatic cell nuclear transfer (SCNT) embryo represents a small percentage of donor cells that survived the reprogramming gauntlet. The inability to reprogram histone modifications in the donor cell line could add to the reprogramming deficiencies associated with SCNT. The effects of two histone modifications associated with transcriptional activation (H3K4m3 and H4K16ac) and two histone modifications associated with repressing transcription (H3K9m2 and H3K27me3) were evaluated in the context of their association to three genes known to contribute to maintaining totipotency: Nanog, Oct4, and Sox2. A µChIP assay was utilized using antibodies specific for each histone modification followed by real time PCR (qPCR) analysis to quantify the percentage of each gene associated with each particular histone modification. Gene expression analysis was followed by immunofluorescence and protein analysis. Results of these analyses suggest that gene association to certain histone modifications did not accurately predict gene expression in bovine blastocyst embryos. Of the three genes studied, only Oct4 expression differed significantly between in vitro fertilized (IVF; control) and SCNT blastocysts. Protein levels detected through immunofluorescence correlated directly with the gene expression analysis. Nanog and Sox2 expression profiles of IVF and SCNT bovine blastocysts are similar, yet the histone modification profiles associated with all three genes differ significantly. Altered expression levels in developmentally important genes will likely result in abnormal activity of the associated cellular pathway. Aberrant histone modifications, along with abnormal Oct4 expression, may contribute to the low percentage of SCNT embryos that result in live offspring.

On the temperature dependence of the shape of magnetica resonance lines
Creators: name: McMillan, Malcolm
Publisher: name: University of British Columbia
Year: 2012

description: This thesis is devoted to a theoretical study of that temperature dependence of the shape of magnetic resonance lines in solids which remain when the direct effect of lattice vibrations can be neglected. This is the case at sufficiently low temperatures. To discuss the shape of resonance lines the "moment method" is used. This procedure was introduced by Van Vleck (1948) and was used also by Pryce and Stevens (1950) and Usui and Kambe (1952). A line shape function which describes the shape of the resonance lines is defined and the first and second moments of this function are calculated in various approximations. In particular, the question to what extent the standard formula of Van Vleck for the second moment is valid is discussed in great detail. The general formulae are applied to the case of a spherical sample of nickel fluosilicate crystal. From the general discussions and from this special case it follows that the temperature dependence of the characteristics of paramagnetic resonance lines becomes noticeable at liquid helium temperatures and that these characteristics are then also dependent on the shape of the sample.

description: We show that high quality laser guide star (LGS) adaptive optics (AO) observations of nearby early-type galaxies are possible when the tip-tilt correction is done by guiding on nuclei while the focus compensation due to the changing distance to the sodium layer is made 'open loop'. We achieve corrections such that 40% of flux comes from R<0.2 arcsec. To measure a black hole mass (Mbh) one needs integral field observations of both high spatial resolution and large field of view. With these data it is possible to determine the lower limit to Mbh even if the spatial resolution of the observations are up to a few times larger than the sphere of influence of the black hole.

Radiative corrections to pion-nucleus bremsstrahlung

description: We calculate the one-photon loop radiative corrections to virtual pion Compton scattering $π^- γ^* \to π^- γ$, that subprocess which determines in the one-photon exchange approximation the pion-nucleus bremsstrahlung reaction $π^- Z\to π^- Z γ$. Ultraviolet and infrared divergencies of the loop integrals are both treated by dimensional regularization. Analytical expressions for the ${\cal O}(α)$ corrections to the virtual Compton scattering amplitudes, $A(s,u,Q)$ and $B(s,u,Q)$, are derived with their full dependence on the (small) photon virtuality $Q$ from 9 classes of contributing one-loop diagrams. Infrared finiteness of these virtual radiative corrections is achieved (in the standard way) by including soft photon radiation below an energy cut-off $λ$. In the region of low $π^- γ$ center-of-mass energies, where the pion-nucleus bremsstrahlung process is used to extract the pion electric and magnetic polarizabilities, we find radiative corrections up to about -3% for $λ=5 $MeV. Furthermore, we extend our calculation of the radiative corrections to virtual pion Compton scattering $π^-γ^* \to π^- γ$ by including the leading pion structure effect in form of the polarizability difference $α_π- β_π$. Our analytical results are particularly relevant for analyzing the data of the COMPASS experiment at CERN which aims at measuring the pion electric and magnetic polarizabilities with high statistics using the Primakoff effect.

description: Solovay proved that there exists a computable upper bound f of the prefix-free Kolmogorov complexity function K such that f (x) = K(x) for infinitely many x. In this paper, we consider the class of computable functions f such that K(x) <= f (x)+O(1) for all x and f (x) <= K(x) + O(1) for infinitely many x, which we call Solovay functions. We show that Solovay functions present interesting connections with randomness notions such as Martin-Löf randomness and K-triviality.

description: Augmented Reality (AR) has recently become a very popular research and innovation domain in various industries, allowing the connection of the physical world with digital entities, enriching human experience through dynamic interactions in a mixed reality. Increased computational speed has allowed this technology to become more feasible and widespread, especially in commercial uses, such as marketing, promotion, entertainment and education. Tourism and cultural heritage have experienced significant changes and an increase in user-experience satisfaction, through the application of AR. The application of game design principles and digital storytelling has become a favorite approach of communication for history and cultural heritage. In this context, storytelling is a largely important characteristic of any AR application. Based on this concept, an animated AR storytelling approach is presented in this paper that is capable of bringing stories of the past to life, through animation and AR. Light-weight animated 3D characters, 3D scenes, and various 3D objects have been created, to represent scenarios of ancient battles, using cutting-edge game mechanics and narration from multimodal documentation. The approach includes age-based scenario personalization. The particular scenarios implemented present the story “from combat to burial” using opponent ancient warriors in a one-to-one melee setting, from two different ages, the Mycenaean and the Roman. The implementation uses actual museum digital replicas and historical documentation provided by experts, and aims to show the practice and traditions relating to combats and their outcomes. The paper presents key design concepts of the particular application, as well as technical aspects surrounding its implementation relating to visual and auditory realism.

Publisher: name: Utah State University

description: Single nucleotide polymorphisms (SNPs) are single base-pair variations that exist between individuals. There are approximately a million or more SNPs located throughout the genome of each individual animal. Therefore, by taking advantage of these unique polymorphisms, SNPs can be used to resolve questions of unknown parentage in the livestock industry. Currently a panel of 88 SNPs, obtained from a panel of 121 SNPs originally created by USDA-MARC, is commercially available from Fluidigm®. The objective of this study was to determine whether the number of SNPs from the 88-SNP marker panel could be reduced to form a smaller, more cost-efficient parentage-testing SNP panel. A smaller panel would benefit farmers and researchers alike in reducing the time spent in running and analyzing the test, as well as reducing the overall cost for the procedure. Genotype data from over 3000 cattle samples containing offspring and potential parents were examined using two parentage calling software packages. Parentage assessment was analyzed using nine SNP panels of varying size. It was determined that a panel of 71 SNPs, chosen from the original 88 SNPs, was the minimum number required to maintain statistical accuracy and reliability.

description: We present a computer simulation model for the Hanbury Brown-Twiss experiment that is entirely particle-based and reproduces the results of wave theory. The model is solely based on experimental facts, satisfies Einstein's criterion of local causality and does not require knowledge of the solution of a wave equation. The simulation model is fully consistent with earlier work and provides another demonstration that it is possible to give a particle-only description of wave phenomena, rendering the concept of wave-particle duality superfluous.

The T([alpha,gamma]) Li⁷ reaction and a standard Geiger-Muller counter for gamma ray flux determinations
Creators: name: Morrow, Richard Alexander
Publisher: name: University of British Columbia
Year: 2012

description: A study of the T(α,ɤ)Li⁷ reaction has been made at mean alpha particle energies of 1320, 560 and 350 Kev in a solid tritium-zirconium target. At the 1320 Kev energy the absolute 90° differential cross-section for transitions to the ground state has been found to be 1.89x10⁻³¹ cm² per steradian from analyses of spectra obtained in a 2¾"x4½” NaI crystal. At this energy the ratio of the differential cross-section for transitions to the first excited state to that for transitions to the ground state was found to be 0.446. This ratio was observed to remain the same at all detector angles. The excitation function roughly determined by additional runs at 560 and 350 Kev mean energy followed the form obtained by Riley of this laboratory in 1958. Angular distribution measurements at 1320 Kev gave the result that both the above mentioned gamma rays have the same angular dependence, this being 1-0.11 cos² θ + 0.39 cos⁴ θ. At 560 Kev mean energy their anisotropy was measured to be about 5%. A background from the target has been found to have an angular distribution at 1320 Kev mean alpha particle energy of 1+0.35 cos θ in laboratory co-ordinates. Both its excitation function, determined roughly from runs at 560 and 350 Kev, and its anisotropy followed a form in agreement with neutron counter measurements. It is suggested that this background is caused by neutrons from some still unknown reaction in the target. An investigation was also made of a standard thick-walled brass Geiger-Muller counter to determine its efficiency for photon energies from 0.5 to 20 Mev. A smooth curve was obtained showing efficiency increasing with gamma ray energy thus agreeing in form with previous experimental and theoretical results.

description: The debate about which similarity measure one should use for the normalization in the case of Author Co-citation Analysis (ACA) is further complicated when one distinguishes between the symmetrical co-citation--or, more generally, co-occurrence--matrix and the underlying asymmetrical citation--occurrence--matrix. In the Web environment, the approach of retrieving original citation data is often not feasible. In that case, one should use the Jaccard index, but preferentially after adding the number of total citations (occurrences) on the main diagonal. Unlike Salton's cosine and the Pearson correlation, the Jaccard index abstracts from the shape of the distributions and focuses only on the intersection and the sum of the two sets. Since the correlations in the co-occurrence matrix may partially be spurious, this property of the Jaccard index can be considered as an advantage in this case.

description: We discuss here a long Suzaku observation of IRAS 19254-7245 (also known as the Superantennae), one of the brightest and well studied Ultra Luminous Infrared Galaxies in the local Universe. This long observation provided the first detection of IRAS 19254-7245 above 10 keV, and measured a 15-30 keV flux of ~5x10^(-12) erg cm^-2 s^-1. The detection above 10 keV has allowed us to unveil, for the first time, the intrinsic luminosity of the AGN hosted in IRAS 19254-7245, which is strongly absorbed (Nh ~ 3x10^(24) cm^-2) and has an intrinsic luminosity in the QSO regime (L(2-10 keV) ~ 3 x 10^(44) erg s^-1). The 2-10 keV spectrum of IRAS 19254-7245 is remarkably hard (Gamma~1.2), and presents a strong iron line (EW ~0.7 keV), clearly suggesting that below 10 keV we are seeing only reprocessed radiation. Since the energy of the Fe K emission is found to be at ~6.7 keV, consistent with He-like Fe, and its EW is too high to be explained in a starburst dominated scenario, we suggest that the 2--10 keV emission of IRAS 19254-7245 is dominated by reflection/scattering from highly ionized matter. Indeed, within this latter scenario we found that the photon index of the illuminating source is Gamma=1.87 (+0.11,-0.28), in excellent agreement with the mean value found for radio quiet unobscured AGN.

The spin glass part of the starting Hamiltonian contains Ising spins with an intersite exchange interaction given by the local van Hemmen model, while the Kondo effect is described as usual by the intrasite exchange $J_K$. We obtain, for large $J_K$ values, a Kondo phase and, for smaller $J_K$ values, a succession, with decreasing

description: The purpose of this study was to explore the role of emotional intelligence (EI) in medical laboratory science, as perceived by laboratory administrators. To collect and evaluate these perceptions, a survey was developed and distributed to over 1,400 medical laboratory administrators throughout the U.S. during January and February of 2013. In addition to demographic-based questions, the survey contained a list of 16 items, three skills traditionally considered important for successful work in the medical laboratory as well as 13 EI-related items. Laboratory administrators were asked to rate each item for its importance for job performance, their satisfaction with the item's demonstration among currently working medical laboratory scientists (MLS) and the amount of responsibility college-based medical laboratory science programs should assume for the development of each skill or attribute. Participants were also asked about EI training in their laboratories and were given the opportunity to express any thoughts or opinions about EI as it related to medical laboratory science. This study revealed that each EI item, as well as each of the three other items, was considered to be very or extremely important for successful job performance. Administrators conveyed that they were satisfied overall, but indicated room for improvement in all areas, especially those related to EI. Those surveyed emphasized that medical laboratory science programs should continue to carry the bulk of the responsibility for the development of technical skills and theoretical knowledge and expressed support for increased attention to EI concepts at the individual, laboratory, and program levels.

description: The supergiant fast X-ray transient (SFXT) system IGR J17544-2619 has displayed many large outbursts in the past and is considered an archetypal example of SFXTs. A search of the INTEGRAL/ISGRI data archive from MJD 52698-54354 has revealed 11 outbursts and timing analysis of the light curve identifies a period of 4.926$\pm$0.001 days which we interpret as the orbital period of the system. We find that large outbursts occasionally occur outside of periastron and place an upper limit for the radius of the supergiant of <23R$_{\sun}$.

title: Improvement in Computational Fluid Dynamics Through Boundary Verification and Preconditioning
Creators: name: Folkner, David E.
Publisher: name: Utah State University
Year: 2013

description: This thesis provides improvements to computational fluid dynamics accuracy and ef- ficiency through two main methods: a new boundary condition verification procedure and preconditioning techniques. First, a new verification approach that addresses boundary conditions was developed. In order to apply the verification approach to a large range of arbitrary boundary condi- tions, it was necessary to develop unifying mathematical formulation. A framework was developed that allows for the application of Dirichlet, Neumann, and extrapolation bound- ary condition, or in some cases the equations of motion directly. Verification of boundary condition techniques was performed using exact solutions from canonical fluid dynamic test cases. Second, to reduce computation time and improve accuracy, preconditioning algorithms were applied via artificial dissipation schemes. A new convective upwind and split pressure (CUSP) scheme was devised and was shown to be more effective than traditional precon- ditioning schemes in certain scenarios. The new scheme was compared with traditional schemes for unsteady flows for which both convective and acoustic effects dominated. Both boundary conditions and preconditioning algorithms were implemented in the context of a "strand grid" solver. While not the focus of this thesis, strand grids provide automatic viscous quality meshing and are suitable for moving mesh overset problems.

description: In their position paper entitled "Towards a new, complexity science of learning and education", Jorg et al. (2007) argue that educational research is in crisis. In their opinion, the transdisciplinary and interdiscursive approach of complexity science with its orientation towards self-organization, emergence, and potentiality provides new modes of inquiry, a new lexicon and assessment practices that can be used to overcome the current crisis. In this contribution, I elaborate on how complexity science can further be developed for understanding the dynamics of intentions and the communication of meaning as these are central to the social-scientific enterprise.
title: Development of sediment budgets at multiple scales
Creators: name: Erwin, Susannah O'Brien
Publisher: name: Utah State University
Year: 2013

description: Channel morphology in alluvial rivers results from the interactions among the flow of water and sediment, the grain size distribution of the material in transport, and the characteristics of the materials making up the channel boundary. Many modern river management problems depend upon the ability to predict channel behavior in response to changes in the delivery of sediment. Sediment budgets provide a framework for explicitly evaluating the links between sediment delivery to and export from a river, and changes in storage. In the work presented here I have developed sediment budgets at three different spatial and temporal scales in an effort to gain insight to channel response to a change in sediment supply. In Chapter 2, I present a bed load budget for the Snake River in Grand Teton National Park (GTNP), Wyoming. The analysis was designed to evaluate the effects of 50 years of flow regulation on net sediment flux and, thus, sediment storage for the Snake River below Jackson Lake Dam. In Chapter 3 I present a sediment mass balance constructed for a single flood on an aggrading 4-km reach of the middle Provo River, Utah. Sediment accumulation in the Provo River had driven significant point bar growth, and the sediment budget was designed to explicitly link patterns in sediment flux with morphologic change. In Chapter 4, I present the results from a physical experiment designed to further evaluate the effect of changing sediment supply on point bar morphology in a single meander bend. The experiment was conducted in a field-scale flume, the Outdoor StreamLab (OSL), at the University of Minnesota. In each of the cases I present here, the channel was subject to sediment accumulation due to either an increase in sediment supply (Provo River and OSL) or a decrease in transport capacity (Snake River). The analyses provide insight into processes governing channel response to changes in sediment supply and highlight the inherent challenges and uncertainties associated with sediment budgets, regardless of the scale of the analysis.

description: We continue our recent work to characterize the plasma content of high-redshift damped and sub-damped Lyman-alpha systems (DLAs/sub-DLAs), which represent multi-phase gaseous (proto)galactic disks and halos seen toward a background source. We survey N V absorption in a sample of 91 DLAs and 18 sub-DLAs in the redshift range 1.67-2.3. The N V and CIV component b-value distributions in DLAs are statistically similar, but the median b(N V) of 18 km/s is lower than the median b(O VI) of 25 km/s. Some ~20% of the N V components have b<10 km/s and thus arise in warm photoionized plasma at log (T/K)<4.92; local sources of ionizing radiation (as opposed to the extragalactic background) are required to keep the cloud sizes physically reasonable. The nature of the remaining ~80% of (broad) N V components is unclear; models of radiatively-cooling collisionally-ionized plasma at log(T/K)=5.2-5.4 are fairly successful in reproducing the observed integrated high-ion column density ratios and the component line widths, but we cannot rule out photoionization by local sources. Finally, we identify several unusual DLAs with extremely low metallicity (<0.01 solar) but strong high-ion absorption [log N(N V)>14 or log N(O VI)>14.2] that present challenges to either galactic inflow or outflow models.

Seismology of beta Cephei stars: differentially-rotating models for interpreting the oscillation spectrum of nu-Eridani

description: A method for the asteroseismic analysis of beta Cephei stars is presented and applied to the star nu Eridani. The method is based on the analysis of rotational splittings, and their asymmetries using differentially-rotating asteroseismic models. Models with masses around 7.13 M_sun, and ages around 14.9 Myr, were found to fit better 10 of the 14 observed frequencies, which were identified as the fundamental radial mode and the three L=1 triplets g, p, and p. The splittings and aymmetries found for these modes recover those provided in the literature, except for p. For this last mode, all its non-axysimmetric components are predicted by the models. Moreover, opposite signs of the observed and predicted splitting asymmetries are found. If identification is confirmed, this can be a very interesting source of information about the internal rotation profile, in particular in the outer regions of the star. In general, the seismic models which include a description for shellular rotation yield slightly better results as compared with those given by uniformly-rotating models. Furthermore, we show that asymmetries are quite dependent on the overshooting of the convective core, which make the present technique suitable for testing the theories describing the angular momentum redistribution and chemical mixing due to rotationally-induced turbulence.

description: We present high-resolution spectral line and continuum VLBI and VLA observations of the nuclear region of NGC 253 at 22 GHz. While the water vapor masers in this region were detected on arcsecond and milliarcsecond scales, we could not detect any compact continuum emission with a 5 sigma upper limit of ~ 1 mJy. The observations reveal that the water maser emission is not related to a possible low-luminosity active galactic nucleus but is almost certainly associated with star-formation activity. Not detecting any compact continuum source on milliarcsecond scales also questions the presence of a - previously assumed - active nucleus in NGC 253.

description: We investigate the structure and mobility of dislocations in hcp 4He crystals. In addition to fully characterizing the five elastic constants of this system, we obtain direct insight into dislocation core structures on the basal plane, which demonstrates a tendency toward dissociation into partial dislocations. Moreover, our results suggest that intrinsic lattice resistance is an essential factor in the mobility of these dislocations. This insight sheds new light on the possible correlation between dislocation mobility and the observed macroscopic behavior of crystalline 4He.

title: Enhanced Structural Support of Metal Sites as Nodes in Metal-Organic Frameworks Compared to Metal Complexes

description: Metal-organic frameworks are a new class of crystalline, porous solid-state materials with metal ions periodically linked by organic linkers. This gives rise to one-, two- or three-dimensional structures. Here, we compare the stability of similar metal sites toward external ligand (solvent) induced disruption of the coordination environment in metal complexes and in metal-organic frameworks. Our experimental results show that a metal site as node of a metal-organic framework retains much higher stability compared to a similar metal site in a metal complex.
