Unconditionally energy stable DG schemes for the Swift-Hohenberg equation
Creators: name: Liu, Hailiang
name: Yin, Peimeng
Publisher: name: arXiv
Year: 2019
Subjects: subject: Numerical Analysis (math.NA)
subject: FOS: Mathematics

description: The Swift-Hohenberg equation as a central nonlinear model in modern physics has a gradient flow structure. Here we introduce fully discrete discontinuous Galerkin (DG) schemes for a class of fourth order gradient flow problems, including the nonlinear Swift-Hohenberg equation, to produce free-energy-decaying discrete solutions, irrespective of the time step and the mesh size. We exploit and extend the mixed DG method introduced in [H. Liu and P. Yin, J. Sci. Comput., 77: 467--501, 2018] for the spatial discretization, and the "Invariant Energy Quadratization" method for the time discretization. The resulting IEQ-DG algorithms are linear, thus they can be efficiently solved without resorting to any iteration method. We actually prove that these schemes are unconditionally energy stable. We present several numerical examples that support our theoretical results and illustrate the efficiency, accuracy and energy stability of our new algorithm. The numerical results on two dimensional pattern formation problems indicate that the method is able to deliver comparable patterns of high accuracy.

Subjects: Academic self-handicapping; Achievement goal orientations; Perceived classroom goal structures; Perceived parent goals; Self-efficacy; Self-esteem

description: The present study aimed to investigate academic self-handicapping in secondary school students. A number of personal factors (achievement goal orientations, self-efficacy, self-esteem, strategy use and prior achievement) as well as students’ perceptions of contextual factors (perceived classroom and parent goals, teacher-student relationship) were tested as potential predictors of academic self-handicapping. A total of 392 7th and 9th graders were asked to complete a set of self-report questionnaires measuring all the above variables adjusted for mathematics. Path analysis indicated that (a) self-efficacy beliefs for mathematics was a negative predictor of academic-self-handicapping, (b) mastery goals negatively predicted self-handicapping via self-efficacy beliefs and (c) perceived teacher-student relationship and parent mastery goals were protective factors for academic self-handicapping via student mastery goals and self-efficacy beliefs. Findings are discussed in light of current theory and evidence, whereas educational implications and limitations are pointed out.

description: This study examined the perceived career decision-making difficulties among Greek student teachers via the Career Decision-Making Difficulties Questionnaire (CDDQ). The Greek version of CDDQ was firstly analyzed with exploratory and confirmatory factor analysis. In a sample of student teachers majoring in humanities and social sciences (N = 780), the initially proposed structure of CDDQ was partially confirmed with seven of the ten anticipated factors present. These factors were used as independent variables in multivariate models predicting participants' overall difficulty during the career decision-making process, the degree of certainty for their choices, and their decision status. Discussion of the findings is provided.

Photometric redshifts in the Hubble Deep Fields: evolution of extinction and the star-formation rate
Creators: name: Rowan-Robinson, Michael
Publisher: name: arXiv
Year: 2003
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Photometric redshifts are studied with a template approach using data from HDF-N and -S . The problem of aliasing in photometric redshift estimates is investigated in some detail and found not to be a significant problem if at least four photometric bands are available. The performance of the approach presented here appears to exceed that of others in the literature. With reasonable restrictions, it is possible to determine the dust extinction as well as the photometric redshift, provided five or more photometric bands are available. An important result is that evolution of with redshift is seen, with higher values than locally at z = 0.5-1.5, and lower values at z > 2. This is consistent with current models for the star formation history of the universe. Deconvolving the uv-to-ir seds into an old star and young star component allows determination of M_* and \dot{M}_* for each galaxy, as well as z_{phot} and A_V, provided that infrared photometric bands are available. The expected trend of b = M_*/\dot{M}_* t_0 increasing to the past is seen. However there is a great deal of scatter in the relation between b and sed type, showing that the recent star-formation history is not very well correlated with the long-term history of a galaxy. The 2800 A luminosity function and star-formation rate are calculated for a large sample of HDF-N (2490) and HDF-S (28719) galaxies, using photometric redshifts, for the redshift range 0.2-5. The star-formation rates agree reasonably well with those from a variety of other uv, $H_α$, infrared and submillimetre estimates, and with star-formation histories used to model optical, infrared and submillimetre source-counts.

description: Malaysian palm oil will continue to compete strongly in world markets with soybean and other vegetable oils for the rest of this century. Production -could reach 6 million tons in 1990 and 8 million tons in 2000 under the best possible conditions. In more likely scenarios, production would be 5.1 to 5.4 million tons in 1990 and 6.7 to 7.5 million tons in 2000. Malaysia will need to export about 4 million tons in 1990 and 5 million tons in 2000.

description: With the escalating frequency of extreme grid disturbances, such as natural disasters, comes an increasing need for efficient recovery plans. Algorithms for optimal power restoration play an important role in developing such plans, but also give rise to challenging mixed-integer nonlinear optimization problems, where tractable solution methods are not yet available. To assist in research on such solution methods, this work proposes PowerModelsRestoration, a flexible, open-source software framework for rapidly designing and testing power restoration algorithms. PowerModelsRestoration constructs a mathematical modeling layer for formalizing core restoration tasks that can be combined to develop complex workflows and high performance heuristics. The efficacy of the proposed framework is demonstrated by proof-of-concept studies on three established cases from the literature, focusing on single-phase positive sequence network models. The results demonstrate that PowerModelsRestoration reproduces the established literature, and for the first time provide an analysis of restoration with nonlinear power flow models, which have not been previously considered.

title: EXPERIENCE AND SOLIPSISM
Creators: name: Millar, Roderick David Gartley
Publisher: name: The Open University
Year: 1980

description: We begin by noting that the thesis that experience is never of material objects but is rather of sense-data does, when coupled with certain plausible enough empiricist theses regarding knowledge and sense, seem to lead to dramatic solipsistic challenges to common belief about the world. After clarifying key concepts such as those of experience, sense-data, material objects and sensibilia we argue that the arguments for the specific sense-data thesis themselves require that the thesis be reconciled with the substance of common belief about the world, e.g. that there are material objects etc. However, we argue that the two principal sorts of attempt at such reconciliation, representative realism and phenomenalism, are far from immediately convincing. On the other hand, however, we remain unconvinced by Wittgenstein’s ’private language argument’, the point of which seems to be to establish that experience could not be of private objects such as sense-data. Neither do we find Strawson’s treatment of persons the bullwark against solipsism which it may at first appear. In view of the difficulty into which the general thesis that experience is never of material objects leads us we give the arguments normally adduced in favour of this thesis a more thorough examination. Our main concern here is not just to establish that this thesis is mistaken but to discover precisely where and how mistakes may have been made. We identify errors in all the arguments and so continue to maintain a position of ’direct surface realism’, i.e. the position that our experience is largely of the surfaces of material objects. In this way we find that we are not committed to the sense-data thesis and can, consequently, avoid the solipsistic positions into which we seemed to be forced by the thesis if we also accepted the empiricist theses of knowledge and sense.
A magnetic confinement nuclear fusion mechanism for solar flares
Creators: name: Zhang, Ying-Zhi
Publisher: name: arXiv
Year: 2019
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: We propose a magnetic confinement nuclear fusion mechanism for the evolution of a solar flare in solar atmosphere. The mechanism agree with two observed characteristics of explosive flares and coronal mass ejections (CMEs) that have proved to be very difficult to explain with previous mechanisms: the huge enrichments of $^{3}He$ and the high energy gamma ray radiation. The twisted magnetic flux rope is a typical structure during the solar flares, which is closely related to the solar active region that magnetic fields have almost complete control over the plasma. Consequently, the plasma inside the flux rope is heated to more than 1.0$\times10^{7}$ K by adiabatic compression process, and then the thermonuclear fusion can take place in the flux rope accompanied with high energy gamma rays. We utilize the time-dependent ideal 2.5-dimensional magnetohydrodynamic (MHD) simulation to demonstrate the physical mechanism for producing flares, which reveals three stages of flare development with process of magnetic energy conversion and intense release during the solar flares and CMEs in solar atmosphere. Furthermore, we discuss the relationship between magnetic reconnection and solar eruptions.
INTERTWINED AND INCOMPATIBLE IDENTITIES IN THE ARGUMENTATION AGAINST THE INSTITUTIONALIZATION OF SAME SEX COUPLES’ COHABITATION AGREEMENT: "GREEK-ORTHODOXY" AND HOMOSEXUALITY
Creators: name: Michos, Ioannis

Year: 2020
Subjects: Cohabitation agreement; Identities; LGBTQI; Same-sex couples

description: This research focuses on the ways in which "Greek-Orthodox" social identity is constructed and used as an argumentative resource against the institutionalization of same-sex couples’ cohabitation agreement. The analytic material consisted of comments put forward in the context of a public online deliberation on this issue held in Greece in 2015. Analysis, which used the principles of critical discursive psychology and rhetoric, highlights the construction of a solid "Greek-Orthodox" identity in which the concepts of "nation" and "religion" presuppose each other while at the same time they establish heteronormativity. Moreover, homosexuality is constructed as a “sin” that is incompatible with the "Greek-Orthodox" identity while the legal protection of same-sex relationships is represented as a threat to the Greek nation. These constructions are orientated to manage social accountability concerns of the commentators, while at the same time they potentially contribute to the preservation of hierarchical structures and power relations aiming to undermine LGBTQI+ claims. Key words: Cohabitation agreement, Identities, Same-sex couples

Corvus cecilae marngli Mathews, 1912b: 52 (Marngle Creek, West Kimberley, West Australia).
Now Corvus bennetti North, 1901. See Mathews, 1926: 403–406; Hartert, 1929a: 54; Mathews, 1930: 895; Blake and Vaurie, 1962: 276; Rowley, 1970; Schodde and Mason, 1999: 608; and dos Anjos, 2009: 633.
HOLOTYPE: AMNH 674578, adult male, collected at Manguel (= Marngle) Creek, 17.49S, 123.39E (Johnstone and Storr, 2004: 510), West Kimberley, Western Australia, Australia, on 1 June 1911, by J.P. Rogers (no. 1712). From the Mathews Collection (no. 9396) via the Rothschild Collection.
COMMENTS: Mathews gave his catalog number of the holotype in the original description, noting that the wing measured 312 mm and that the bill was shorter than that of C. cecilae. Mathews (1926: 403–406) does not give further measurements for marngli. My measurements: wing 313, bill 51, tarsus 57. These fall within the measurements given by Rowley (1970: 59, 63) for C. bennetti.

description: We have measured temperature and magnetic field dependences of the thermal conductivity along the c-axis, kc, and that along the [110] direction, k110, of CuB2O4 single crystals in zero field and magnetic fields along the c-axis and along the [110] direction. It has been found that the thermal conductivity is nearly isotropic and very large in zero field and that the thermal conductivity due to phonons is dominant in CuB2O4. The temperature and field dependences of kc and k110 have markedly changed at phase boundaries in the magnetic phase diagram, which has been understood to be due to the change of the mean free path of phonons caused by the change of the phonon-spin scattering rate at the phase boundaries. It has been concluded that thermal conductivity measurements are very effective for detecting magnetic phase boundaries.

This report summarizes current efforts to further develop a more disaggregated perspective of financial indicators. Balance sheets and various financial ratios are presented by type of farm for selected years. Although the analysis performed indicates that most types of farms experienced some deterioration in their financial position between 1969 and 1982, the development of micro measures is needed to obtain more reliable and accurate barometers of the financial well-being of farms.

COMMENTS: Mathews gave a range of wing measurements, 314–327, for perplexus in the original description. This subspecies was usually considered a synonym of C. c. coronoides until Schodde and Mason (1999: 613–614) recognized perplexus as the name applicable to the southwestern Australian population. This was followed by dos Anjos (2009: 633–634).

description: This paper investigated how sensitive food price is to changes in petroleum price and exchange rate in Ghana from January 1997 to August 2017. Interest rate was included as a control variable in the study since it may be a useful macroeconomic policy tool. Using Johansen cointegration procedure, Vector Error Correction Model, Impulse Response Functions and BEKK-GARCH estimations, the results of the study showed there exist positive long-run and short-run relationships between food prices and all the macroeconomic variables used in the model. Thus, increases in petroleum price, exchange rate and interest rate raise food prices in Ghana. The magnitudes of these increases were found to be very high during the food crises periods in 2007/08 and 2010/11. It was also found that effects of these food price spikes caused by shocks from petroleum price, exchange rate and interest rate are long lasting and do not decay easily with time. The results from the BEKK-GARCH estimation showed that food prices in Ghana exhibit time-varying volatility; caused by its own ARCH and GARCH effects as well as exogenously determined shocks from petroleum price, exchange rate and interest rate. Also, the results indicated that food price volatility shocks in Ghana are persistent. It is recommended that; policy aimed at food price stabilization must build national petroleum buffer stocks to stabilize fuel prices, improve exchange rate and interest rate management, build district, regional and national food buffer stocks, selectively target fuel subsidy at crop farmers and food processors, and remove bottlenecks in food marketing.

title: The history of corrosion technology (up to about the time of the First World War)
Creators: name: Smith, C. A.
Publisher: name: The Open University
Year: 1976

description: In this work, the author examines the problems that metallic corrosion has caused through the ages, and the attempts that have been made to combat it, particularly from the technological point of view. The period under special consideration is the nineteenth century. During that time, two aspects of the industrial revolution highlighted the problems that corrosion can cause. The quantity of iron and steel produced, increased enormously, so an ever increasing volume of metal became exposed to air and water. At the same time, the environmental pollution from the very furnaces and other manufacturing establishments that were producing the iron and steel, served to increase the aggressive nature of the corrosive attack. These two factors combined to make industrialists fully aware of the magnitude of the problem and this resulted in detailed investigations being carried out to attempt to quantify the amount of corrosion occurring in various environments and with different grades of iron and steel. During the nineteenth century, engineers tended to concentrate on ferrous metals and scientists on non-ferrous metals. Centuries ago, it was appreciated that the important factor in the prevention of corrosion, was for the metal to be separated from any aggressive environment. Many attempts have been made since then to find a covering that would become firmly attached to the metal surface and prevent ingress of the corroding media. Until about 1836, these attempts had been made empirically, but at that time, the principles of galvanic protection, which had been established earlier in the century, began to be put into practice. Tin had been applied as a covering for centuries, prior to these discoveries, primarily because of its decorative appeal. Scientists were now able to appreciate that the protection given by tin was just mechanical, whereas zinc, bestowed both mechanical and electrochemical protection. This realisation increased the popularity of zinc as a protective material. Electroplating became firmly established during the century, especially when 'magneto-electric machines' superceded the battery and provided a reliable current supply. Little scientific thought was given to painting until nearly the end of the century, when red lead became firmly established as the most suitable base for use.

description: The livelihood asset is a primary concern in support of household livelihoods, poverty elimination and enhancing sustainable development, particularly true for mining communities. Underpinned by this, the general objective of the study was to assess the impact of small-scale mining activities on the livelihood assets of households in the Bekwai Municipality, Ghana. The study areas included were mining (Kokotro and Koniyaw) and non-mining (Poano and Ntinanko) communities within Bekwai Municipality with 400 household sample size. The Propensity Score Matching (PSM) was used to generate propensity scores to estimate the average mining effect on the household assets. The results revealed that that the household financial assets were positively (3.15) impacted by the activities of Small-Scale Mining (SSM) activities while natural capital was negatively impacted (-4.15) followed by human capital (-3.78) and social capital (-3.25). Virtually, the negatively affected households do nothing (45%) as a coping strategy while others also relied on efforts by District Assembly Taskforce (27). It is recommended that the severe negative impact on the natural assets needs an urgent and strict supervision on mining concession sites and also calls for an alternative source of livelihood activities (cash crops, palm plantation and processing) which are prospects for the government’s policy of planting for food and agriculture and one district one factory.
Neutrino Masses Induced by R-Parity Violation in a SUSY SU(5) Model with Additional \bar{5}'_L+5'_L

description: Within the framework of an SU(5) SUSY GUT model, a possible general form of the neutrino mass matrix induced by R-parity violation is investigated. The model has matter fields \bar{5}'_{L}+5'_{L} in addition to the ordinary matter fields \bar{5}_{L}+10_{L} and Higgs fields H_u+\bar{H}_d. The R-parity violating terms are given by \bar{5}_{L} \bar{5}_{L} 10_{L}, while the Yukawa interactions are given by \bar{H}_d \bar{5}'_{L} 10_{L}. Since the matter fields \bar{5}'_L and \bar{5}_L are different from each other at the unification scale, the R-parity violation effects at a low energy scale appear only through the \bar{5}'_L \leftrightarrow \bar{5}_{L} mixings. In order to make this R-parity violation effect harmless for proton decay, a discrete symmetry Z_3 and a triplet-doublet splitting mechanism analogous to that in the 5-plet Higgs fields are assumed.

description: The following document contains our team’s detailed design report for the UBC Wesbrook Mall Phase 4 Redesign from Thunderbird Boulevard to West 16th Avenue. The project’s objectives are to: (1) Expand roadway capacities, (2) Minimize costs, (3) Incorporate a pedestrian tunnel or overpass, (4) Increase green space to improve stormwater retention, (5) Create a dedicated bike facility, (6) Maximize parking, (7) Minimize tree removals, and (8) overall, prioritize buses, cyclists and pedestrians by maximizing safety, convenience and enjoyability in using these transport modes. This report will summarize the detailed design including a design overview, issue-for-construction drawings, cost estimate, schedule, construction management and service life maintenance plan. The selected design includes a two-way, elevated bike lane along southbound Wesbrook Mall, the addition of a transit priority lane along northbound Wesbrook Mall, curb extensions, rain gardens and tree box filters for drainage, and a pedestrian overpass south of Doug Mitchell Thunderbird Sports Centre. The key considerations for this design have remained consistent throughout the duration of the project and address technical, economic, environmental, regulatory, construction planning and societal perspectives. To arrive at the detailed design, a structural analysis for the overpass and a traffic analysis to inform the geometric design were conducted. The detailed design has a Class A cost estimate of CAD $8.4 million and the project is on track to begin construction in May, 2022 and is expected to be completed by October, 2022. The project’s next steps include tendering the project and obtaining relevant permits and approvals.

Corvus marianae mellori Mathews, 1912a: 443 (South Australia).
Now Corvus mellori Mathews, 1912. See Mathews, 1926: 390–402; Hartert, 1929a: 53; Mathews, 1930: 894–895; Blake and Vaurie, 1962: 276– 277; Rowley, 1967; 1970: 50–53; Schodde and Mason, 1999: 611; and dos Anjos, 2009: 634.
HOLOTYPE: AMNH 674602, male, collected on Angas Plains, 35.21S, 139.00E (USBGN, 1957), South Australia, Australia, on 31 December 1901, by Edwin Ashby (no. 290). From the Mathews Collection (3724, not 5724) via the Rothschild Collection.
COMMENTS: In the original description, Mathews said only that his type was from South Australia, gave inclusive wing measurements, 326–330 mm, without stating the sex, and noted that the feather bases were gray. He also gave his catalog number of the holotype as 5724, but this was a typographical error, the correct number being 3724. (The entry at no. 5724 is a specimen of Neochmia phaeton.) Hartert (1929a: 53) did not catch this error in Mathews’ catalog number.
Rowley (1967) elevated this form to full species status and gave measurements of the holotype: wing 326 mm, bill 54 mm, tarsus 62 mm. Schodde and Mason (1999: 611) and dos Anjos (2009: 634) accepted species status for C. mellori.
Corvus marianae halmaturinus is a synonym of mellori (see below) and was described on the same page. Rowley (1970: 50) served as first revisor when he chose mellori to have priority over halmaturinus.
[A second specimen of mellori, AMNH 674489, cataloged by Mathews as no. 3723, ‘‘ Corvus coronoides,’’ also a male, was collected on 30 December 1901 on Angas Plains. This specimen was identified in the AMNH catalog as Corvus bennetti but is a raven with gray feather bases. It was collected by Edwin Ashby and identified as Corvus coronoides by him. I measure the wing as 318 mm, bill 50 mm, tarsus, 57 mm, which fall within the measurements given by Rowley (1970: 51) for males of mellori from inland New South Wales and South Australia. This topotype is retained with the types.]

description: This report describes socioeconomic changes in local economies following closure of a military base. Comparisons are drawn between effects in nonmetro and metro counties, and between counties experiencing a base-closing and all other counties. Despite extreme variation in economic growth among base-closing counties, three intriguing conclusions are found: 1) job losses tended to constitute a higher percentage of total employment in nonmetro counties than in metro counties; 2) of the 83 base-closing counties studied, one-third did not regain as many civilian jobs as were lost; 3) growth rates for employment, income, and population were slower in the average nonmetro base-closing county than in both the average metro base-closing county and the average nonmetro county nationwide.

description: The Philippines relies entirely on imports to meet all of its wheat demand. Wheat marketing and distribution have been controlled by the private sector since 1986. The milling industry consists of 2 milling associations and 12 mills. The key factor in wheat importers' purchasing decisions is the price of wheat, with quality being the second most important factor. Between two high-quality sources, price is the more important factor; however, between an inferior and superior source, quality factors override price considerations. Protein and moisture are the most important quality characteristics. In general, dockage was not listed as one of the top five quality factors determining the country supplier. Selling cleaner U.S. wheat would result in possible premiums, although the amount of the premium is not known. In terms of the trade effects of cleaner U.S. wheat, all millers indicated that lower dockage levels, at the current price, would not result in an increase in demand for U.S. wheat imports in the short term.

description: The production of correlated Stokes (S) and anti-Stokes (aS) photons (SaS process) mediated by real or virtual phonon exchange has been reported in many transparent materials. In this work, we investigate the polarization and time correlations of SaS photon pairs produced in a diamond sample. We demonstrate that both S and aS photons have mainly the same polarization of the excitation laser. We also perform a pump-and-probe experiment to measure the decay rate of the SaS pair production, evidencing the fundamental diference between the real and virtual (phonon exchange) processes. In real processes, the rate of SaS pair production is governed by the phonon lifetime of $(2.8 \pm 0.3)$ ps, while virtual processes only take place within the time width of the pump laser pulses of approximately 0.2 ps. We explain the diference between real and virtual SaS processes by a phenomenological model, based on probabilities of phonon creation and decay.
A comprehensive set of elemental abundances in damped Ly-alpha systems: revealing the nature of these high-redshift galaxies

description: By combining our UVES-VLT spectra of a sample of four damped Ly-alpha systems (DLAs) toward the quasars Q0100+13, Q1331+17, Q2231-00 and Q2343+12 with the existing HIRES-Keck spectra, we covered the total spectral range from 3150 to 10000 A for the four quasars. This large wavelength coverage and the high quality of the spectra allowed us to measure the column densities of up to 21 ions, namely of 15 elements - N, O, Mg, Al, Si, P, S, Cl, Ar, Ti, Cr, Mn, Fe, Ni, Zn. Such a large amount of information is necessary to constrain the photoionization and dust depletion effects, two important steps in order to derive the intrinsic chemical abundance patterns of DLAs. We evaluated the photoionization effects with the help of the Al+/Al++, Fe+/Fe++, N0/N+ and Ar/Si,S ratios, and computed dust corrections. Our analysis revealed that the DLA toward Q2343+12 requires important ionization corrections. The access to the complete series of relatively robust intrinsic elemental abundances in the other three DLAs allowed us to constrain their star formation history, their age and their star formation rate by a detailed comparison with a grid of chemical evolution models for spiral and dwarf irregular galaxies. Our results show that the galaxies associated with these three DLAs in the redshift interval z_abs = 1.7-2.5 are either outer regions of spiral disks (radius >= 8 kpc) or dwarf irregular galaxies (with a bursting or continuous star formation history) with ages varying from some 50 Myr only to >~ 3.5 Gyr and with moderate star formation rates per unit area of -2.1 < log ψ< -1.5 M_{sol} yr^{-1} kpc^{-2}.

description: Supersymmetric effective potential of a 5D super-Yang-Mills model compactified on $S^1/Z_2$, i.e., on an interval $l$ of extra dimension, is estimated at the 1-loop level by the auxiliary field tadpole method. For the sake of infinite towers of Kaluza-Klein excitation modes of bulk fields involved in the tadpoles, there arises a definite bulk effect of linear growth of the effective potential along with the cutoff ${\mitΛ}$ which is greatly suppressed by $l$ to produce finite contributions. The minimization of the effective potential incorporating the tree potential and a Fayet-Iliopoulos $D$-term reveals an interesting case that the size of $l$ is stabilized at a length corresponding to an intermediate mass scale $10^{12-14}$ GeV.
