description: A series of MgB$_2$ thin films systematically disordered by neutron irradiation have been studied by Scanning Tunneling Spectroscopy. The c-axis orientation of the films allowed a reliable determination of local density of state of the $π$ band. With increasing disorder, the conductance peak moves towards higher voltages and becomes lower and broader, indicating a monotonic increase of the $π$ gap and of the broadening parameter. These results are discussed in the frame of two-band superconductivity.

Relation between bare lattice coupling and MSbar coupling at one loop with general lattice fermions
Creators: name: Adams, David H.
Publisher: name: arXiv
Year: 2006
Subjects: subject: High Energy Physics - Lattice (hep-lat)
subject: FOS: Physical sciences

description: A compact general integral formula is derived from which the fermionic contribution to the one-loop coefficient in the perturbative expansion of the MSbar coupling in powers of the bare lattice coupling can be extracted. It is seen to reproduce the known results for unimproved naive, staggered and Wilson fermions, and has advantageous features which facilitate the evaluation in the case of improved lattice fermion formulations. This is illustrated in the case of Wilson clover fermions, and an expression in terms of known lattice integrals is obtained in this case which gives the coefficient to much greater numerical accuracy than in the previous literature.

description: In an attempt to model the accretion onto a neutron star in low-mass X-ray binaries, we present two-dimensional hydrodynamical models of the gas flow in close vicinity of the stellar surface. First we consider a gas pressure dominated case, assuming that the star is non-rotating. For the stellar mass we take $M_{\rm star}=1.4 \times 10^{-2} \msun$ and for the gas temperature $T=5 \times 10^6$ K. Our results are qualitatively different in the case of a realistic neutron star mass and a realistic gas temperature of $T\simeq 10^8$ K, when the radiation pressure dominates. We show that to get the stationary solution in a latter case, the star most probably has to rotate with the considerable velocity.

Grand Challenges in Planetary Nebulae Studies: Binary Evolution and MHD

description: We review work on the evolution of planetary nebulae and proto-planetaries via magneto-rotational mechanisms showing that a dynamo generated magnetic field can produce the energy and momentum needed to drive pPN and PNe outflows. Angular momentum considerations lead to the conclusion that single stars may not be capable of supporting strong fields for long times. Thus we take the working hypothesis that most PN may form via binary stars. We propose that the grand challenge for PN studies is fully understanding the diverse physical processes at work in binary late stage evolution including the development of disks, fields and outflows.

Sustainability and the urban landscape: introduction of a qualitative assessment tool for understanding and enhancing sustainability in urban open space
Creators: name: Petersen, Susan Christine
Publisher: name: University of British Columbia
Year: 2009

description: This project introduces a way of operationalizing the idea of sustainability by applying its principles to open space in the urban landscape. Landscape is defined as the land surface, composed of a mosaic of ecosystems and land uses, that provides the setting for human activities. The rationale for the project is that people are deeply influenced by and keenly interested in landscape features, so landscape can serve as a medium for learning about sustainability because our ways of using land form part of the broader picture of our relationship with the earth. The landscape of urban areas deserves attention because urban dwellers experience it daily and sometimes exclusively, and because of the global trend toward urbanization of natural landscapes. Sustainability is conceptualized as a system characteristic that arises from three other necessary conditions within the system: provision for ecological viability, provision of adequate human life quality and consideration of equity. A landscape ecological model of sustainability was operationalized by linking its variables to urban open space features via indicators constructed from literature sources and based on visual assessment of observable landscape conditions. Use of this landscape assessment tool (set of indicators) was demonstrated by assessing several test sites in an urban district. The tool's usability was partially examined through trials with potential users. Three broad conclusions are drawn from the project. First, findings from the test sites indicate that amenity functions in the urban landscape are only moderate and ecological functions are unexpectedly high despite management for amenity. This suggests that urban ecosystems could flourish and serve as repositories of ecological function if they were enhanced by planning and management. Secondly, the urban open space assessment tool shows potential for usefully operationalizing sustainability theory, though more testing of its educational value and accuracy is needed. Finally, the sustainability model used in the project shows that sustainability requires the achievement of human well-being through the satisfaction of social needs as well as material sufficiency and ecological integrity. Satisfaction of these different needs can be complementary and can be achieved within systems of human activity such as urban open space use.
Swift/BAT and RXTE/ASM Observations of the 35-day X-ray Cycle of Hercules X-1

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: Swift/BAT and RXTE/ASM observations have monitored the X-ray binary system Her X-1 for approximately 14.5 years each, and both were monitoring Her X-1 for a period of ~5.5 years. Here we study the 35-day cycle using these observations. Using a cross-correlation method we find the times of peaks of the 35-day cycles for ~150 cycles observed by Swift/BAT and ~150 cycles observed by RXTE/ASM. These cycles include ~60 observed with both instruments. The noise level of the RXTE/ASM measurements is larger than that of Swift/BAT, resulting in larger uncertainty in peak times. The distribution of 35-day cycle lengths can be fit with a Gaussian with mean 34.79 d and $σ$ of 1.1 d. The distribution of orbital phases of 35-day cycle peaks is well fit by a uniform distribution, with 76 percent of the cycles, plus a Gaussian distribution peaked at orbital phase ~0.5, with 24 percent of the cycles. We construct the long-term average 35-day lightcurve in the 15-50 keV band from Swift/BAT, and in the 2-12 keV band from RXTE/ASM. The high energy band shows more variability in the Short High state and the low energy band shows more variability in the Main High state. This is consistent with a precessing accretion disk model as cause of the 35-day cycle.

description: We present high-resolution radio interferometric imaging observations of the radio source NVSS J182659+343113 (hereafter J1826+3431), the proposed radio counterpart of the $γ$-ray source, 3EG J1824+3441 detected by the Energetic Gamma Ray Experiment Telescope (EGRET) on board the Compton Gamma Ray Observatory satellite. We analyzed eight epochs of archival multi-frequency very long baseline interferometry data. We imaged the asymmetric core-jet structure of the source, and detected apparent superluminal motion in the jet. At the highest observing frequency, 15.3 GHz, the core shows high brightness temperature indicating Doppler boosting. Additionally, the radio features undergo substantial flux density variability. These findings strengthen the previous claim of the association of the blazar J1826+3431 with the possible $γ$-ray source, 3EG J1824+3441.

description: We report a series of magnetic and transport measurements on high-quality single crystal samples of colossal magnetoresistive manganites, La_{0.7} Ca_{0.3} Mn O_3 and Pr_{0.7} Sr_{0.3} Mn O_3. 1 % Fe doping allows a Moessbauer spectroscopy study, which shows (i) unusual line broadening within the ferromagnetic phase and (ii) a coexistence of ferro- and paramagnetic contributions in a region, T_1T_2. This shows that phase separation into metallic (ferromagnetic) and insulating (paramagnetic) phases cannot be generally responsible for the resistivity peak (and hence for the associated colossal magnetoresistance). Our results can be understood phenomenologically within the two-fluid approach, which also allows for a difference between T_C and T_{MI}. Our data indeed imply that while magnetic and transport properties of the manganites are closely interrelated, the two transitions at T_C and T_{MI} can be viewed as distinct phenomena.

description: The phase field fracture method has emerged as a promising computational tool for modelling a variety of problems including, since recently, hydrogen embrittlement and stress corrosion cracking. In this work, we demonstrate the potential of phase field-based multi-physics models in transforming the engineering assessment and design of structural components in hydrogen-containing environments. First, we present a theoretical and numerical framework coupling deformation, diffusion and fracture, which accounts for inertia effects.Several constitutive choices are considered for the crack density function, including choices with and without an elastic phase in the damage response. The material toughness is defined as a function of the hydrogen content using an atomistically-informed hydrogen degradation law. The model is numerically implemented in 2D and 3D using the finite element method. The resulting computational framework is used to address a number of case studies of particular engineering interest. These are intended to showcase the model capabilities in: (i) capturing complex fracture phenomena, such as dynamic crack branching or void-crack interactions, (ii) simulating standardised tests for critical components, such as bolts, and (iii) enabling simulation-based paradigms such as Virtual Testing or Digital Twins by coupling model predictions with inspection data of large-scale engineering components. The evolution of defects under in-service conditions can be predicted, up to the ultimate failure. By reproducing the precise geometry of the defects, as opposed to re-characterising them as sharp cracks, phase field modelling enables more realistic and effective structural integrity assessments.

description: Objectives: To examine the validity and reliability of the Dutch language short Anterior Cruciate Ligament—Return to Sport after Injury scale (short ACL-RSI-NL) in recreational athletes undergoing rehabilitation after ACL injury or ACL reconstruction (ACLR). Methods: The original 12-item version of the ACL-RSI had been translated into Dutch. Short ACL-RSI-NL items were derived from this 12-item Dutch version. Content validity was evaluated by a team consisting of eight ACL experts and eight athletes. A cohort of 115 athletes with ACL injury or after ACLR completed the short ACL-RSI-NL and related questionnaires at various time points during their rehabilitation. Construct validity (hypothesis testing using Spearman correlations), internal consistency (Cronbach's alpha), floor and ceiling effects (percentage of athletes having the lowest or highest score possible), and structural validity (exploratory factor analysis) were evaluated in the entire ACL athlete group. Test-retest reliability (using intra-class correlation, ICC; standard error of measurement, SEM; smallest detectable change, SDC, at both group and individual levels) was investigated in a subgroup of athletes with a stable outcome on psychological readiness within a two-week interval (n ​= ​27). Results: The short ACL-RSI-NL demonstrated good construct validity (83% of hypotheses confirmed). Internal consistency was excellent (Cronbach's alpha 0.84), and there were no floor and ceiling effects (≤13.9% lowest or highest score). Test-retest reliability was good (ICC 0.89 with 95% CI 0.77–0.95, SEM 6.93, SDC individual level 19.2, SDC group level 3.7). Exploratory factor analysis confirmed the presence of a single underlying factor (accounting for 56.4% of the total variance of the score). Conclusion: The short ACL-RSI-NL exhibited good to excellent construct validity, internal consistency, and test-retest reliability. An averaged score ranging from 0 to 100 can be used to measure psychological readiness to return to sport. The short ACL-RSI-NL has potential for use in day-to-day practice to assess the psychological readiness of recreational athletes to return to sport after ACL injury or ACLR during their rehabilitation process. Level of evidence: Level II.

description: The origin and evolution of neutron-capture elements in our Galaxy is poorly understood. In this work, we have attempted to understand the Galactic s-process nucleosynthesis using barium stars as probes. We have performed high resolution spectroscopic analysis for three barium stars HD 36650, HD 207585 and HD 219116. The analysis of HD 219116 is based on HCT/HESP data at a resolution of 60,000 covering a wavelength region 3530-9970 {\rm Å}. For HD 36650, we have used the FEROS spectrum at a resolution of 48,000 covering the wavelength region 3520-9200 {\rm Å}. For HD 207585, the spectrum from VLT/UVES at a resolution of 48,000 covering the wavelength region 3290-6650 {\rm Å} is used. Our analysis clearly shows that the surface chemical composition of these barium stars are enriched by s-process nucleosynthesis products coming from their former companion low-mass AGB stars. A discussion on the distribution of abundance ratios based on the existing nucleosynthesis theories is presented.
The internet, society and politics : political participation in Australia

description: This thesis examines the effects of internet use on Australian citizens' propensity to participate in political activity. The study applies the 'civic voluntarism' model of political participation to the Australian case, theorising that internet use comprises a resource. It hypothesises that participation in Australia is a factor of an individual's free time, time spent using the internet, money, civic skills, internet-related skills, recruitment and engagement. Australia is an appropriate case study due to its institutional and cultural similarities with other advanced democracies, as well as its notable differences. Voting is compulsory for Australian citizens, and they are compelled to vote frequently and in complex systems. Previous research has found that compulsory voting has positive effects on participation between elections, as well as on the stability of the country's political parties. Australians have ample opportunity to participate in politics. The thesis analyses 2010 (and earlier) Australian Election Study data, supplemented by data from previous Australian Election Studies, the World Values Survey and Comparative Study of Electoral Systems. Descriptive, logistic regression and ordinary least squares regression analyses find that internet use leads to participation earlier in life than would occur otherwise, but that participants possess the high socioeconomic status of participants in other advanced democracies. Skills are particularly important: across a range of behaviours including electoral, campaign, communal and protest participation, the positive influence of internet proficiency over time spent online is evident. However, the determinants vary greatly between types of participatory act, revealing lowered costs of entry, and opportunities for low-resourced citizens to equip themselves to participate. The findings have implications for understanding how the internet impacts the changing face of participation in Australia, how citizens can be mobilised in the future and the prognosis for the health of Australia's participatory democracy.

Modifying these coordinates in a certain way (keeping their interpretation as initial values at large distances), we still have a synchronous frame and the direct analogue of the Lemaitre metric, the singularities of which are exhausted by the physical Kerr singularity (the singularity ring).

description: The pressure-induced changes in the optical properties of the quasi-one-dimensional conductor LaTiO$_{3.41}$ were studied by polarization-dependent mid-infrared micro-spectroscopy at room temperature. For the polarization of the incident radiation parallel to the conducting direction, the optical conductivity spectrum shows a pronounced mid-infrared absorption band, exhibiting a shift to lower frequencies and an increase in oscillator strength with increasing pressure. On the basis of its pressure dependence, interpretations of the band in terms of electronic transitions and polaronic excitations are discussed. Discontinuous changes in the optical response near 15 GPa are in agreement with a recently reported pressure-induced structural phase transition and indicate the onset of a dimensional crossover in this highly anisotropic system.

How Intellectual Communities Progress

Subjects: subject: History and Philosophy of Physics (physics.hist-ph)
subject: FOS: Physical sciences

description: Recent work takes both philosophical and scientific progress to consist in acquiring factive epistemic states such as knowledge. However, much of this work leaves unclear what entity is the subject of these epistemic states. Furthermore, by focusing only on states like knowledge, we overlook progress in intermediate cases between ignorance and knowledge -- for example, many now celebrated theories were initially so controversial that they were not known. This paper develops an improved framework for thinking about intellectual progress. Firstly, I argue that we should think of progress relative to the epistemic position of an intellectual community rather than individual inquirers. Secondly, I show how focusing on the extended process of inquiry (rather than the mere presence or absence of states like knowledge) provides a better evaluation of different types of progress. This includes progress through formulating worthwhile questions, acquiring new evidence, and increasing credence on the right answers to these questions. I close by considering the ramifications for philosophical progress, suggesting that my account supports rejecting the most negative views while allowing us to articulate different varieties of optimism and pessimism.

Ice emission and the redshifts of submillimeter sources

description: Observations at submillimeter wavelengths have revealed a population of sources thought to be at relatively large redshifts. The position of the 850 $μ$m passband on the Rayleigh-Jeans portion of the Planck function leads to a maximum redshift estimate of $z\sim$4.5 since sources will not retain their redshift independent brightness close to the peak of the Planck function and thus drop out of surveys. Here we review evidence that ice absorption is present in the spectra of local ultraluminous infrared galaxies which are often taken as analogs for the 850 $μ$m source population. We consider the implication of this absorption for ice induced spectral structure at far infrared wavelengths and present marginal astronomical evidence that amorphous ice may have a feature similar to crystalline ice near 150 $μ$m. Recent corroborative laboratory evidence is supportive of this conclusion. It is argued that early metal enrichment by pair instability SN may lead to a high ice content relative to refractory dust at high redshift and a fairly robust detection of ice emission in a $z=6.42$ quasar is presented. It is further shown that ice emission is needed to understand the 450 $μ$m sources observed in the GOODS-N field. We are thus encouraged to apply far infrared ice emission models to the available observations of HDF 850.1, the brightest submillimeter source in the {\it Hubble Deep Field}. We suggest that a redshift as large as 13 may need to be considered for this source, nearly a factor of three above the usual top estimate. Inclusion of the possibility of far infrared ice emission in the spectral energy distributions of model sources generally broadens the range of redshifts to be considered for submillimeter sources compared to models without ice emission.

description: We explore the range of parameters for dark-matter sterile neutrinos in an extention of the Minimal Standard Model by three singlet fermions with masses below the electroweak scale (the $ν$MSM). This simple model can explain a wide range of phenomena, including neutrino oscillations, baryogenesis, the pulsar velocities, and the early reionization. The presence of two heavier sterile neutrinos and the possibility of entropy production in their decays broadens the allowed range of parameters for the dark-matter sterile neutrinos (or other types of dark matter, for example, the gravitino). In addition, the primordial production of dark matter sterile neutrinos allows to escape most of the constraints.

We argue that this implies that successful k-essence models violate causality. It is not possible to define a time ordered succession of events in a Lorentz invariant way. Therefore, k-essence cannot arise as low energy effective field theory of a causal, consistent high energy theory.

The relationship between Maori and the New Zealand government, as with indigenous groups and governments in other settler societies, is profoundly affected by historical events and the contemporary understandings of those events. I identify key strengths and weaknesses in the relationship at Tongariro National Park, and investigate their historical origins. I argue that the local relationship between the Department of Conservation and Maori is hampered by the different expectations for the relationship each party brings to the negotiating table. These differing expectations stretch back to the establishment of the park in the late nineteenth century, and were enshrined during the early twentieth century in the legislation, policy and public attitudes that structure the national park institution. The relationship's strengths included the goodwill with which both parties usually engaged with each other, the longevity of key relationships, and the political nous of local Maori leaders. These features date back to the 1970s and 1980s when the introduction of public consultation in park decision making led to the development of personal relationships between park management staff and Maori. Claimant and Crown interpretations of the park's history were strongly shaped by the incentive structures of the inquiry process, leading to emphasis on certain events and aspects of the historical relationship that, in my analysis, were not always the most significant. Tribunal inquiries tend to be strongly adversarial, and the inquiry over Tongariro National Park put stress on personal relationships in the area. The usual patterns of interaction between Maori and the Department of Conservation were disrupted during and after the hearings. This may be only a short-term effect, but is noteworthy as one of the goals of the Treaty settlement process is to support ongoing relationships between Maori and the New Zealand government, and little work has been done into the impact of the inquiry process on relationships ""on the ground.""

description: Selecting a suitable development method for a specific project context is one of the most challenging activities in process design. Every project is unique and, thus, many context factors have to be considered. Recent research took some initial steps towards statistically constructing hybrid development methods, yet, paid little attention to the peculiarities of context factors influencing method and practice selection. In this paper, we utilize exploratory factor analysis and logistic regression analysis to learn such context factors and to identify methods that are correlated with these factors. Our analysis is based on 829 data points from the HELENA dataset. We provide five base clusters of methods consisting of up to 10 methods that lay the foundation for devising hybrid development methods. The analysis of the five clusters using trained models reveals only a few context factors, e.g., project/product size and target application domain, that seem to significantly influence the selection of methods. An extended descriptive analysis of these practices in the context of the identified method clusters also suggests a consolidation of the relevant practice sets used in specific project contexts.

description: A tagged medium-energy neutron beam has been used in a precise measurement of the absolute differential cross section for np back-scattering. The results resolve significant discrepancies within the np database concerning the angular dependence in this regime. The experiment has determined the absolute normalization with 1.5% uncertainty, suitable to verify constraints of supposedly comparable precision that arise from the rest of the database in partial wave analyses. The analysis procedures, especially those associated with evaluation of systematic errors in the experiment, are described in detail so that systematic uncertainties may be included in a reasonable way in subsequent partial wave analysis fits incorporating the present results.

description: The ongoing, fluid nature of the COVID-19 pandemic requires individuals to regularly seek information about best health practices, local community spreading, and public health guidelines. In the absence of a unified response to the pandemic in the United States and clear, consistent directives from federal and local officials, people have used social media to collectively crowdsource COVID-19 elites, a small set of trusted COVID-19 information sources. We take a census of COVID-19 crowdsourced elites in the United States who have received sustained attention on Twitter during the pandemic. Using a mixed methods approach with a panel of Twitter users linked to public U.S. voter registration records, we find that journalists, media outlets, and political accounts have been consistently amplified around COVID-19, while epidemiologists, public health officials, and medical professionals make up only a small portion of all COVID-19 elites on Twitter. We show that COVID-19 elites vary considerably across demographic groups, and that there are notable racial, geographic, and political similarities and disparities between various groups and the demographics of their elites. With this variation in mind, we discuss the potential for using the disproportionate online voice of crowdsourced COVID-19 elites to equitably promote timely public health information and mitigate rampant misinformation.

description: The most startling examples of collective animal behaviour are provided by very large and cohesive groups moving in three dimensions. Paradigmatic examples are bird flocks, fish schools and insect swarms. However, because of the sheer technical difficulty of obtaining 3D data, empirical studies conducted to date have only considered loose groups of a few tens of animals. Moreover, these studies were very seldom conducted in the field. Recently the STARFLAG project achieved the 3D reconstruction of thousands of birds under field conditions, thus opening the way to a new generation of quantitative studies of collective animal behaviour. Here, we review the main technical problems in 3D data collection of large animal groups and we outline some of the methodological solutions adopted by the STARFLAG project. In particular, we explain how to solve the stereoscopic correspondence - or matching - problem, which was the major bottleneck of all 3D studies in the past.

description: We present the calculation for single-inclusive jet production in (longitudinally) polarized deep-inelastic lepton-nucleon scattering at next-to-next-to leading order (NNLO) accuracy, based on the Projection-to-Born method. As a necessary ingredient to achieve the NNLO results, we also introduce the next-to-leading-order (NLO) calculation for the production of di-jets in polarized DIS. Our di-jet calculation is based on an extension of the dipole subtraction method to account for polarized initial-state partons. We analyze the phenomenological consequences of higher order QCD corrections for the Electron-Ion Collider kinematics.

description: We study the effect that size disorder in the cations surrounding manganese ions has on the magnetic properties of manganites. This disorder is mimic with a proper distribution of spatially disordered Manganese energies. Both, the Curie temperature and the order of the transition are strongly affected by disorder. For moderate disorder the Curie temperature decreases linearly with the the variance of the distribution of the manganese site energies, and for a disorder comparable to that present in real materials the transition becomes first order. Our results provide a theoretical framework to understand disorder effects on the magnetic behavior of manganites.

The interaction of Cyclosporin A with Lipoproteins
Creators: name: Donnachie, Elizabeth Mary
Publisher: name: University of British Columbia

description: The success of transplantation has been largely attributed to the introduction of the immunosuppressant, Cyclosporin A (CsA). However, patients receiving CsA frequently become dyslipidemic and this is thought to augment the nephrotoxic and hepatotoxic effects by interfering with the distribution and pharmacokinetics of CsA in plasma. In addition, CsA alone can cause hypercholesterolemia, which is believed to contribute to the pathogenesis of post-transplant atherosclerosis and coronary artery disease. The mechanism of CsA-induced hypercholesterolemia is unknown but it has been suggested that CsA affects the uptake of LDL at the level of the LDL-receptor. The objectives of this thesis were two-fold: 1) to test the hypothesis that CsA contributes to dyslipidemia by decreasing the cellular uptake of LDL via the LDL-receptor and 2) to determine how lipoproteins affect the binding and distribution of CsA in human plasma. To investigate the effect(s) of CsA on LDL uptake via the LDL-receptor, the binding, internalization, and degradation of ¹²⁵I-LDL In vitro was measured in human skin fibroblasts. The results show that CsA does not decrease LDL binding. Further, CsA did not decrease the Bm a x or Kd of the LDL for its receptor, nor did it decrease LDL-receptor mRNA levels. Contrary to my expectations, CsA significantly increased LDL degradation. To determine whether the association of CsA with LDL had any effect on the binding of LDL to its receptor, CsA was equilibrated with ¹²⁵I-LDL prior to its incubation with human skin fibroblasts. These results demonstrate that the association of CsA with LDL did not affect the binding or Kd of LDL to its receptor. Collectively, these data show that CsA does not reduce L D L uptake by decreasing the binding, internalization, or degradation of L D L and this suggests that decreasing LDL uptake via the LDL-receptor is not a mechanism by which CsA contributes to hyperlipidemia in patients receiving this drug. To investigate CsA's distribution in dyslipidemic plasma, CsA was added to plasma from the following groups: normolipidentic, hypercholesterolemic, hypertriglyceridemic, hypoalphalipoproteinemic, and a combination of hypercholesterolemic and hypertriglyceridemic. By using the phosphotungstic acid precipitation method to fractionate plasma, it was shown that the distribution of CsA in all of the dyslipidemic groups was significantly different from the normolipidentic control. In addition, the amount of CsA associated with the VLDL/LDL and HDL fractions was quite variable between the groups but the amount with the LPDP fraction remained relatively constant. These data suggest that factors other than the amount of lipid, such as the composition of the lipoprotein, play a role in the distribution of CsA.
