description: In this paper, we consider the hypothesis in which a species of ultra light bosonic dark matter (ULBDM) with mass $m_{B}\sim 10^{-22}$ eV could be the dominant dark matter (DM) in the Universe. As a first approach we work in the context of kinetic theory, where ULBDM is described by the phase space distribution function whose dynamics is dictated by the Boltzmann-Einstein equations. We investigate the effects that this kind of dark matter imprints in the acoustic peaks of the cosmic microwave background. We find that the effect of the Bose-Einstein statistics is small, albeit perceptible, and is equivalent to an increase of non-relativistic matter. It is stressed that in this approach, the mass-to-temperature ratio necessary for ULBDM to be a plausible DM candidate is about five orders of magnitude. We show that reionization is also necessary and we address a range of consistent values for this model. We find that the temperature of ULBDM is below the critical value, impliying that Bose-Einstein condensation is inherent to the ULBDM paradigm.

title: Testing of Rainflow Histograms of Strain for Implementation as a Bridge Weigh-in-Motion Technique
Creators: name: Johnson, Nephi R.
Publisher: name: Utah State University
Year: 2015

description: This research was done as part of a long term project, with the goal to monitor multiple bridges over an extended period of time. Due to the nation’s aging infrastructure and the limited amount of funds to upgrade and maintain it, structural health monitoring (SHM) is very important because it provides in depth information about a structure to be used in decision making. SHM of bridges includes monitoring the effects of traffic loads. This paper discusses the development of a bridge weigh-in-motion (B-WIM) technique that uses the rainflow counting of strain cycles. Typical B-WIM techniques have proven to be accurate but require large algorithms and gauges at multiple locations across the span, and the strain gauge temperature drift must be accounted for. The rainflow B-WIM (RF-BWIM) decreases the processing of the B-WIM and automatically accounts for drift, thus allowing temperature and other analyses of the same bridge to be possible. RF-BWIM also has the potential to decrease the number of sensors required. Strain data taken from an existing long term monitoring system was used to develop the RF-BWIM. The development of the RF-BWIM, as well as a method to determine a virtual gross vehicle weight (C-GVW) used in calculating the RF-BWIM output, is presented.
title: Producing an Ovine Model of Cystic Fibrosis
Creators: name: Morgado, Kira Perry
Publisher: name: Utah State University

description: Cystic Fibrosis (CF) is an autosomal recessive disease that significantly affects quality of life and lifespan. There are currently no effective animal models of CF that mimic the human disease state. This prevents the development of pharmaceutical treatments for patients. Sheep have been considered for a useful animal model because of their size, life expectancy, and similarities in their anatomy and physiology. In order to generate a sheep transgenic model to study CF we have produced two Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) gene targeting DNA vectors containing large regions of homology to the CFTR gene in sheep. One of these targeting vectors (ΔF508Neo) contains sequences designed to delete the phenylalanine at amino acid position 508 of CFTR. Another targeting vector (G27XDTNeo) contains sequences designed to introduce an early stop codon into the CFTR gene such that no CFTR is produced. These two targeting vectors were used to transfect White Romney fibroblast cells. Donor sheep oocytes were collected for use in somatic cell nuclear transfer (scNT) with the two genetically modified cell lines. Embryos produced from scNT were transferred to recipient ewes which resulted in the birth of 11 ΔF508 heterozygous lambs and 3 G27XDT heterozygous lambs
Chaotic motion in classical fluids with scale relativistic methods

description: In the framework of the scale relativity theory, the chaotic behavior in time only of a number of macroscopic systems corresponds to motion in a space with geodesics of fractal dimension 2 and leads to its representation by a Schrödinger-like equation acting in the macroscopic domain. The fluid interpretation of such a Schrödinger equation yields Euler and Navier-Stokes equations. We therefore choose to extend this formalism to study the properties of a system exhibiting a chaotic behavior both in space and time which amounts to consider them as issued from the geodesic features of a mathematical object exhibiting all the properties of a fractal `space-time'. Starting with the simplest Klein-Gordon-like form that can be given to the geodesic equation in this case, we obtain a motion equation for a `three fluid' velocity field and three continuity equations, together with parametric expressions for the three velocity components which allow us to derive relations between their non-vanishing curls. At the non relativistic limit and owing to the physical properties exhibited by this solution, we suggest that it could represent some kind of three-dimensional chaotic behavior in a classical fluid, tentatively turbulent if particular conditions are fulfilled. The appearance of a transition parameter ${\cal D}$ in the equations allows us to consider different ways of testing experimentally our proposal.

description: We consider the area and entropy spectra of black holes in topologically massive gravity with gravitational Chern-Simons term. The examples we consider are the BTZ black hole and the warped AdS black hole. For the non-rotating BTZ black hole, the area and entropy spectra are equally spaced and independent of the coupling constant $\v$ of the Chern-Simons term. For the rotating BTZ black hole case, the spectra of the inner and outer horizon areas are not equally spaced in general and dependent of the coupling constant $\v$. However the entropy spectrum is equally spaced and independent of the coupling constant $\v$. For the warped AdS black holes for $\v >1$ by using the quasinormal modes obtained without imposing the boundary condition at radial infinity we find again that the entropy spectrum is equally spaced and independent of the coupling constant $\v$, while the spectra of the inner and outer horizon areas are not equally spaced and dependent of the coupling constant $\v$. Our result implies that the entropy spectrum has a universal behavior regardless of the presence of the gravitational Chern-Simons term, and therefore it implies that the entropy is more `fundamental' than the horizon area.

title: Statistical Dependence in Imputed High-Dimensional Data for a Colorectal Cancer Study
Creators: name: Suyundikov, Anvar
Publisher: name: Utah State University
Year: 2015

description: The main purpose of this dissertation was to examine the statistical dependence of imputed microRNA (miRNA) data in a colorectal cancer study. The dissertation addressed three related statistical issues that were raised by this study. the first statistical issue was motivated by the fact that miRNA expression was measured in paired tumor-normal samples of hundreds of patients, but data for many normal samples were missing due to lack of tissue availability. We compared the precision and power performance of several imputation methods, and drew attention to the statistical dependence induced by K-Nearest Neighbors (KNN) imputation. The second statistical issue was raised by the necessity to address the bimodality of distributions of miRNA data along with the imputation-induced dependency among subjects. We proposed and compared the performance of three nonparametric methods to identify the dierentially expressed miRNAs in the paired tumor-normal data while accounting for the imputation-induced dependence. The third statistical issue was related to the development of a normalization method for miRNA data that would reduce not only technical variation but also the variation caused by the characteristics of subjects, while maintaining the true biological dierences between arrays.

description: We study the statistical properties of the network constructed from the energy dissipation rate time series in the three dimensional developed turbulence using the visibility algorithm. The degree distribution is found to have a power-law tail with the tail exponent $α=3.0$. The exponential relationship between the number of the boxes $N_B$ and the box size $l_B$ in the edge-covering box-counting method illustrates that the network is not self-similar, which is also confirmed by the hub-hub attraction according to the visibility algorithm. In addition, it is found that the skeleton of the visibility network exhibits excellent allometric scaling with the scaling exponent $η=1.163\pm0.005$.

title: St. John Chrysostom's and Philip Melanchthon's Views of Justification (ΔΙΚΑΙΩΣΙΣ) in St. Paul's Epistles, With Special Attention to How Their Respective Intellectual Environments Influenced Their Interpretations
Creators: name: Davis, Cameron
Publisher: name: Utah State University
Year: 2015

description: This thesis compares how Christian thinkers John Chrysostom (349-407 CE) and Philip Melanchthon (1497-1560 CE) understood the theological concept of justification as found in Paul’s epistle to the Romans, and how their respective intellectual environments influenced their understandings of justification. Through detailed analysis of how Chrysostom and Melanchthon defined the theological concepts underlying their views of justification, it is demonstrated that, while their descriptions of justification often seem amicable, these apparent similarities are superficial. Their primary disagreement rests in their understandings of righteousness, which, for Chrysostom, was the outcome of a synergistic process wherein the faithful Christian gradually became, in actuality, more righteous by cooperating with the will and grace of God. Furthermore, Chrysostom viewed righteousness as a distinct stages in one’s struggle for salvation that followed one’s justification. Melanchthon rejected the notion that human beings themselves could become righteous, instead positing that faithful Christians are justified and simultaneously declared righteous by God based solely on their trust in the saving power of Christ’s atoning death.

The Influence of William Blake on the poetry and prose of Dylan Thomas
Creators: name: Grant, Hugh Joseph
Publisher: name: University of British Columbia
Year: 2011

description: The purpose of this study is to investigate the nature and extent of Dylan Thomas's artistic debt to William Blake. "Chapter I" of our study documents Thomas's professional interest in Blake, offering evidence that Thomas read Blake extensively and carefully. Further, evidence is presented of Thomas's admiration of Blake as a poet and his stated desire to emulate him. "Chapter II" traces Thomas’s direct borrowings from Blake in his 18 Poems as well as in a short story. Because Northrop Frye's idea of the importance of and significance of literary borrowing and literary allusion dictates the direction of much of our argument, our discussion attempts to show the significance of Thomas's borrowings; the implication is that Thomas's imagination shared certain archetypal similarities to that of Blake's. The method of investigation used throughout the thesis, then, has involved a detailed examination of the poems of both poets with the purpose in mind of indicating, where possible, the archetypal significance of the borrowing. "Chapter III" attempts to establish Thomas's direct debt to Blake for many of his images and concepts in his "Altarwise by Owl-Light" sonnet sequence. Our implication is that Thomas was directly influenced in writing the sequence by his knowledge of Blake's epics Vala and Milton. Evidence is presented, in fact, that Thomas borrowed certain of the images for his sonnets from Blake's epics. The preoccupation of both Blake and Thomas with the sinister female will aspect of love in marriage is investigated in "Chapter IV"; our argument implies that Blake derived much of his attitude toward married love from Milton, and through both Milton and Blake, Thomas inherited a somewhat similar attitude. At all times, however, our chief concern is with the poetry resulting from these underlying tensions. There emerges from our study evidence of a striking similarity in artistic vision between Blake and Thomas. Our tracing of literary archetypes (in Northrop Frye's definition) and analogues in the poems leads to the conclusion that Thomas saw the universe from a somewhat similar point of view to that of Blake. "Chapter V" compares Blake’s Jerusalem with Thomas's last poems to establish a correspondence of achieved vision. The comparison is validated, and our argument proceeds to show that, while Thomas was attempting to move in a similar visionary direction to Blake in terms of art, Blake far outstripped the Welsh poet from the point of view of achieved total vision expressed through poetry. Our conclusion follows that, while Thomas, throughout his artistic career, was influenced by Blake and borrowed from him, he found himself at a creative impasse out of which he attempted to work by turning to voice drama in the form of a dramatic and highly imaginative documentary called Under Milk Wood, and even this, his last work, is in some ways reminiscent of Blake's influence.

description: We present a simulation protocol that allows for efficient sampling of the degrees of freedom of a solute in explicit solvent. The protocol involves using a non-equilibrium umbrella sampling method, in this case the recently developed adaptively biased molecular dynamics method, to compute an approximate free energy for the slow modes of the solute in explicit solvent. This approximate free energy is then used to set up a Hamiltonian replica exchange scheme that samples both from biased and unbiased distributions. The final accurate free energy is recovered via the WHAM technique applied to all the replicas, and equilibrium properties of the solute are computed from the unbiased trajectory. We illustrate the approach by applying it to the study of the puckering landscapes of the methyl glycosides of $α$-L-iduronic acid and its C5 epimer $β$-D-glucuronic acid in water. Big savings in computational resources are gained in comparison to the standard parallel tempering method.

title: Methods of Processing Kenaf Chopped Strand Mats for Manufacturing Test Specimens and Composite Structures
Creators: name: Heil, Joshua W.
Publisher: name: Utah State University
Year: 2015

description: Bio-composites are increasing in demand due to governmental incentives across the globe for both environmental and human health reasons. The ideal bio-composite is renewable, recyclable, available, and non-toxic. To properly engineer bio-composite products, the physical properties of the fiber as well as fiber/matrix interactions must be known. The problem lies in the fact that many suitable natural fibers are not currently available in a material form that may be easily worked with. This research investigates methods to process raw kenaf (hibiscus cannabinus) on a scale that allows researchers to make more consistent samples for testing. Though kenaf is highlighted, these processing methods may be applied to any natural fiber. The raw fibers are processed into kenaf chopped strand mats (KCSM) by adapting basic paper-making techniques. KCSM exhibit paper-like qualities and mechanical properties and provide a material of uniform thickness for use in composite parts. Also presented are a basic understanding of natural fiber constituents and effects of mechanical and co-mechanical treatments on those constituents. To test KCSM, samples are made for the ASTM D3039 tensile testing and for testing in a dynamic material analyzer (DMA). Both mechanically and chemo-mechanically processed samples are made for the purpose of comparison. Also, I-beam bridges are built with KCSM to demonstrate how KCSM may be used to create a structure. This is spurred on by the annual SAMPE bridge competition that includes special categories for natural fiber beams. The lay-up procedure is shown in detail to provide a framework that future competitors may use to build quality I-beams for this competition.
The properties obtained by using the KCSM are competitive with other reported properties for kenaf-based composites. A kenaf I-beam demonstrates a strength-to-weight ratio that is 65% of a berglass I-beam built to the same dimensions. Trade-os of using KCSM are the random 2d-fiber orientation and brittle failure, which are not usually desirable in composite components. The chemically treated samples indicate a higher degree of crystallinity but demonstrate inferior mechanical properties when compared to the untreated samples.

title: Greater Sage-Grouse Seasonal Habitat Models, Response to Juniper Reduction and Effects of Capture Behavior on Vital Rates, in Northwest Utah
Creators: name: Cook, Avery

Year: 2015

description: The greater sage-grouse (Centrocercus urophasianus; sage-grouse) is a species of conservation concern in Utah and range-wide due to declines in populations and threats to sagebrush habitat on which they depend. To effectively conserve the species, detailed site-specific knowledge of ecology and distribution is needed. To expand knowledge of local populations within the West Box Elder Sage Grouse Management Area (SGMA) and gain insights into the effectiveness of vegetation treatments intended to benefit sagegrouse, I radio marked and tracked 123 (68 female, 55 male) sage-grouse and conducted sage-grouse pellet surveys on 19 conifer removal projects.
Widespread habitat restoration measures designed to benefit sage-grouse have highlighted the need for prioritization tools to optimize placement of sage-grouse habitat projects. I generated seasonal habitat models to predict sage-grouse habitat use within the West Box Elder SGMA using a suite of vegetation and topographical predictors and known sage-grouse locations. Model fit was good with brood, early summer, late summer, lekking (early spring), and non-breeding models reporting an AUC of >0.90; nest and winter models reported an AUC of 0.87 and 0.85, respectively. A vegetation disturbance history was built for the study area from 1985 to 2013; however, the vegetation disturbances mapped were not a strong predictor of sage-grouse seasonal habitat-use.
To evaluate effectiveness of conifer reduction treatments I used fecal pellet and in concert with radio-telemetry data. Increased sage-grouse use of conifer treatments was positively associated with sage-grouse presence in adjacent habitats (P = 0.018), percent shrub cover (P = 0.039), and mesic environments within 1000 m of treatments (P = 0.048). Sage-grouse use of conifer treatments was negatively associated with conifer canopy cover (P = 0.048) within 1000 m of treatments.
To investigate sample bias related to individual bird behavior or capture trauma I monitored 204 radio-marked sage-grouse within the West Box Elder and Rich-Morgan- Summit SGMAs in Utah between January 2012 and March 2013. Sage-grouse that flushed one or more times prior to capture had higher brood (P = 0.014) and annual survival (P = 0.027) than those that did not. Sage-grouse that experienced more capture trauma had decreased annual survival probabilities (P = 0.04).
title: Effects of Environmental Water Transfers on Stream Temperatures

Publisher: name: Utah State University

description: Low streamflows and warm stream temperatures, caused mainly from agricultural diversions, currently limit available habitat and productivity of trout, including native Lahontan cutthroat trout in Nevada’s Walker River Basin. Environmental water purchases, which transfer water from willing sellers to instream uses (i.e for fish), are being evaluated to improve instream habitat. To determine which environmental water purchases to prioritize, this study was undertaken to build a computer model in order to simulate stream temperatures under differing environmental water transfer scenarios. Model runs simulate a range of environmental water transfers at major diversions and reservoirs throughout the Walker River Basin. Results indicate that low flows generally coincide with critically warm stream temperatures, cooler stream temperatures exist in the East Walker River, a tributary of the Walker River, during warm seasons which provide good habitat for fish, environmental transfers can improve stream temperatures for some highly impacted reaches by up to 3°C in dry years, and environmental water transfers have a greater effect in dry years than wet years.

description: The Kenyan mango value chain faces high post-harvest losses due to poor market access alongside a lack of storage technologies and processing facilities. Thus, using fruit processing methods, like solar drying, can enhance shelf life and help smallholder farmers access new markets, diversifying income and livelihoods. Nonetheless, the processing of both indigenous and grafted mango fruits is not a very common practice. This study was conducted to support product development targeting processing and marketing to link farmers to both local and export markets. Four independent consumer testing and sensory evaluation rounds on Kitui’s dried mango flakes were conducted in Germany and Kenya. Data were collected via a group tasting by 31 randomly selected participants and an online questionnaire of 304 randomly selected participants. All participants were given samples of different varieties of dried mango flakes with and without additives. Results show that high-quality mango cultivars, like Ngowe, receive high hedonic scores without any additives (honey, sodium metabisulfite, or ascorbic acid). Some varieties positively respond to the treatments and achieve higher scores, e.g., Van Dyke or the indigenous variety Kikamba. The consumers testing in Germany show that extrinsic attributes, such as organic production, fair trade, cooperative, and sustainable labelled flakes open up new opportunities for farmers who aim for the export market. Against findings derived from German panellists, in Kenya, consumers do not show a higher willingness to pay despite having a positive attitude toward sustainability. Thus, the local market should focus on cost-reduction strategies rather than introducing standardisation.

We demonstrate that for sufficiently large tension on the (flat) 3-brane, there are no ghosts at the perturbative level, consistent with results that had previously only been obtained in a specific 5D decoupling limit. These results establish the cascading gravity framework as a consistent infrared modification of gravity.

title: Potential of Forage Kochia and Other Plant Materials in Reclamation of Gardner Saltbush Ecosystems Invaded by Halogeton
Creators: name: Smith, Rob C.
Publisher: name: Utah State University
Year: 2015

description: Gardner saltbush ecosystems are increasingly being invaded by halogeton, a competitive annual weed that increases soil surface salinity and reduces plant biodiversity. This study was established on the Flaming Gorge National Recreation Area, in the Ashley National Forest near Manila, UT to evaluate the ability of forage kochia, Russian wildrye, tall wheatgrass, Indian ricegrass and Gardner saltbush, in monocultures and binary mixtures with Gardner saltbush, to establish and compete in ecosystems dominated by halogeton. A dormant seeding, with and without prior disking, was conducted to determine the ability of plant materials to establish. A spaced-plant evaluation was used to determine the competitive ability of fully established plants by measuring halogeton densities at four 10 cm intervals (10-20, 20-30, 30-40, and 40-50 cm) distal from transplants. Gardner saltbush, tall wheatgrass, and Indian ricegrass did not establish or persist beyond the first year in either study. Conversely, Russian wildrye and forage kochia established and persisted, with Russian wildrye establishment higher (P ≤ 0.05) in the disked treatment (4.5 and 1.7 plants m-2, respectively) and no-till favoring (P ≤ 0.05) forage kochia establishment (2.0 and 0.8 plants m-2, respectively). Spaced-plants of these species reduced halogeton by 52% relative to the control. Furthermore, by the second year of evaluation, the competitive ability of Russian wildrye and forage kochia had extended to 50 cm distal from transplant. Transplant survival and halogeton frequency were highly correlated (r = -0.67, P = 0.0001), indicating the important of persistence. These results suggest that Russian wildrye and forage kochia can establish, persist, and compete with halogeton, thereby providing an opportunity for reclamation of halogeton-invaded areas. Conversely, direct restoration to Gardner saltbush and Indian ricegrass does not appear likely

description: We formulate Horava-Lifshitz cosmology with an additional scalar field that leads to an effective dark energy sector. We find that, due to the inherited features from the gravitational background, Horava-Lifshitz dark energy naturally presents very interesting behaviors, possessing a varying equation-of-state parameter, exhibiting phantom behavior and allowing for a realization of the phantom divide crossing. In addition, Horava-Lifshitz dark energy guarantees for a bounce at small scale factors and it may trigger the turnaround at large scale factors, leading naturally to cyclic cosmology.

title: Laboratory Study on the Effects of Exit Face Inclination of Critical Gradients
Creators: name: Keizer, Richard Allen
Publisher: name: Utah State University
Year: 2015

description: The objective of this research is to help better understand the effects of exit face inclinations on critical gradients. This will lead to more practical ways to predict critical hydraulic gradients and slope stability using soil properties and exit face conditions. Current geotechnical engineering does not consider these factors because they are not thoroughly understood. Despite the attempts to better predict critical gradients, methods developed over 70 years ago to model the heave mechanism are used to model failure mechanisms such as backward erosion (or piping). This critical hydraulic gradient is only calculated by means of the buoyant unit weight of the soil. While modern engineering estimates critical piping gradients near unity, research has shown that calculated critical gradients can largely under-predict actual piping gradients.
The results of this thesis research will help provide an empirical, but mechanism-based, grain-scale model that takes into account the effect of non-horizontal exit faces, and soil properties while assessing the potential for piping initiation to occur. This research is expected to help the understanding of the internal erosion mechanism known as piping, and eventually help to develop more practical ways of predicting and preventing conditions which are susceptible to this type of erosion. This research should be used to initiate more research, develop better methods, and eventually increase public safety with regards to designing and improving earth structures such as dams and levees.

A Representation theorem for measures on infinite dimensional spaces
Creators: name: Harpain, Franz Peter Edward
Publisher: name: University of British Columbia
Year: 2011

description: In this paper we obtain a generalization of the well known Riesz Representation Theorem to the case where the underlying space X is an infinite dimensional product of locally compact, regular and σ-compact topological spaces. In the process we prove that our measures on X correspond to projective limit measures of projective systems of regular Borel measures on the coordinate spaces. An example is given to show that σ-compactness of the coordinate spaces is necessary.

Gamma ray emission from SNR RX J1713.7-3946 and the origin of galactic cosmic rays

description: We calculate the flux of non-thermal radiations from the supernova remnant RX J1713.7-3946 in the context of the non-linear theory of particle acceleration at shocks, which allows us to take into account self-consistently the dynamical reaction of the accelerated particles, the generation of magnetic fields in the shock proximity and the dynamical reaction of the magnetic field on the plasma. When the fraction of particles which get accelerated is of order $\sim 10^{-4}$, we find that the strength of the magnetic field obtained as a result of streaming instability induced by cosmic rays is compatible with the interpretation of the X-ray emitting filaments being produced by strong synchrotron losses in $\sim 100 μG$ magnetic fields. If the X-ray filaments are explained in alternative ways, the constraint on the magnetic field downstream of the shock disappears and the HESS data can be marginally fit with ICS of relativistic electrons off a complex population of photons, tailored to comprise CMB and ambient IR/Optical photons. The fit, typically poor at the highest energies, requires a large density of target photons within the remnant; only a fraction of order $\sim 10^{-6}$ of the background particles gets accelerated; the local magnetic field is of order $\sim 20μG$ and the maximum energy of protons is much lower than the knee energy. Current HESS gamma ray observations combined with recent X-ray observations by Suzaku do not allow as yet to draw a definitive conclusion on whether RX J1713.7-3946 is an efficient cosmic ray accelerator, although at the present time a hadronic interpretation of HESS data seems more likely. We discuss the implications of our results for the GLAST gamma ray telescope, which should be able to discriminate the two scenarios discussed above.

description: Neutron spectroscopy and diffuse neutron scattering on herbertsmithite [ZnCu3 (OH)6Cl2], a near-ideal realisation of the s = 1/2 kagome antiferromagnet, reveal the hallmark property of a quantum spin liquid; instantaneous short-ranged antiferromagnetic correlations in the absence of a time-averaged ordered moment. These dynamic antiferromagnetic correlations are only very weakly dependent of neutron-energy transfer and temperature, and persist up to 25 meV and 120 K. At low energy transfers a shift of the magnetic scattering to low Q is observed with increasing temperature, providing evidence of gapless spinons. It is argued that these observations provide important evidence in favour of RVB theories of (doped) Mott insulators.

Proximity effect at the superconductor - topological insulator interface

description: We study the excitation spectrum of a topological insulator in contact with an s-wave superconductor, starting from a microscopic model, and develop an effective low-energy model for the proximity effect. In the vicinity of the Dirac cone vertex, the effective model describing the states localized at the interface is well approximated by a model of Dirac electrons experiencing superconducting s-wave pairing. Away from the cone vertex, the induced pairing potential develops a p-wave component with a magnitude sensitive to the structure of the interface. Observing the induced s-wave superconductivity may require tuning the chemical potential close to the Dirac point. Furthermore, we find that the proximity of the superconductor leads to a significant renormalization of the original parameters of the effective model describing the surface states of a topological insulator.

A Revisit of the Masuda Flare

Year: 2009
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: We revisit the flare on 1992 January 13, which is now universally termed the "Masuda flare". The revisit is motivated not only by its uniqueness despite accumulating observations of \hxr coronal emission, but also by the improvement of Yohkoh hard X-ray imaging, which was achieved after the intensive investigations on this celebrated event. Through an uncertainty analysis, we show that the hard X-ray coronal source is located much closer to the soft X-ray loop in the re-calibrated HXT images than in the original ones. Specifically, the centroid of the M1-band (23--33 keV) coronal source is above the brightest pixel of the SXT loop by ~5000+/-1000 km (~9600 km in the original data); and above the apex of the 30% brightness contour of the SXT loop by ~2000+/-1000 km (~7000 km in the original data). We suggest that this change may naturally account for the fact that the spectrum of the coronal emission was reported to be extremely hard below ~20 keV in the pre-calibration investigations, whereas it has been considerably softer in the literature since Sato's re-calibration circa 1999. Still, the coronal spectrum is flatter at lower energies than at higher energies, owing to the lack of a similar source in the L-band (14--23 keV), which remains a puzzle.

description: Ultra-Low temperature district heating introduces multiple benefits at network level, as the reduction of heat losses and the improvement of heat generation efficiency. ULTDH also facilitates the integration of low temperatures renewable energy sources and waste heat into the district heating network. Renewable heat sources as solar thermal and heat pumps can be coupled to the district heating network and the buildings through specially designed district heating substations.
