description: We propose a new version of the scalar Weak Gravity Conjecture (WGC) which would apply to any scalar field coupled to quantum gravity. For a single scalar it is given by the differential constraint $V''\leq (2V'''^2/V''-V'''')M_{\text{p}}^2$. It corresponds to the statement that self-interactions of a scalar must be stronger than gravity for any value of the scalar field. We find that the solutions which saturate the bound correspond to towers of extremal states with mass $m^2(ϕ)=m_0^2/((R/m)^2+1/(nR)^2)$, with $R^2=e^ϕ$, consistent with the emergence of an extra dimension at large or small $R$ and the existence of extended objects (strings). These states act as WGC states for the scalar $ϕ$. It is also consistent with the distance swampland conjecture with a built-in duality symmetry. From this constraint one can derive several swampland conjectures. In particular one finds that an axion potential is only consistent if $f\leq M_{\text{p}}$. The conjecture has far reaching consequences and applies to several interesting physical systems: i) Among chaotic inflation potentials only those asymptotically linear may survive. ii) If applied to the radion of the circle compactification of the Standard Model to 3D, the constraint implies that the 4D cosmological constant scale must be larger than the mass of the lightest neutrino, which must be Dirac and in normal hierarchy. iii) It also constraints simplest moduli fixing string models. The simplest KKLT model is compatible with the constraints but the latter may be relevant for some choices of parameters.

description: In the context of the BMBF-funded project ROSI (Reference Implementation for Open Scientometric Indicators), visualisations are being developed and their impact on researchers investigated. For this purpose, only data from open data sources will be collected via persistent identifiers of persons, documents or organisations. Furthermore, a reference implementation based on VIVO will be developed in which various indicators with data from open sources such as Crossref Event Data or Wikidata will be visualized. Interviews and workshops with researchers will be conducted to gather their requirements concerning scientometric data. Findings from the interviews and workshops will be incorporated into the reference implementation in an iterative process. The selection of the indicators, the data aggregation levels and data visualisation types will be addressed. A Registry of Scientometric Data Sources is created as a by-product in which APIs with data relevant for the purposes of scientometrics are captured and made findable. This poster describes the project and presents the current status of the project results. https://tib.eu/rosi-project

description: The phase diagram of the quantum spin-1/2 antiferromagnetic $J^{\,}_{1}$-$J^{\,}_{2}$ XXZ chain was obtained by Haldane using bosonization techniques. It supports three distinct phases for $0\leq J^{\,}_{2}/J^{\,}_{1}<1/2$, i.e., a gapless algebraic spin liquid phase, a gapped long-range ordered Neel phase, and a gapped long-range ordered dimer phase. Even though the Neel and dimer phases are not related hierarchically by a pattern of symmetry breaking, it was shown that they meet along a line of quantum critical points with a U(1) symmetry and central charge $c=1$. Here, we extend the analysis made by Haldane on the quantum spin-1/2 antiferromagnetic $J^{\,}_{1}$-$J^{\,}_{2}$ XYZ chain using both bosonization and numerical techniques. We show that there are three Neel phases and the dimer phase that are separated from each other by six planes of phase boundaries realizing U(1) criticality when $0\leq J^{\,}_{2}/J^{\,}_{1}<1/2$. We also show that each long-range ordered phase harbors topological point defects (domain walls) that are dual to those across the phase boundary in that a defect in one ordered phase locally binds the other type of order around its core. By using the bosonization approach, we identify the critical theory that describes simultaneous proliferation of these dual point defects, and show that it supports an emergent U(1) symmetry that originates from the discrete symmetries of the XYZ model. To confirm this numerically, we perform DMRG calculation and show that the critical theory is characterized by the central charge $c=1$ with critical exponents that are consistent with those obtained from the bosonization approach. Furthermore, we generalize the field theoretic description of direct continuous phase transition to higher dimensions, especially in $d=3$, by using a non-linear sigma model (NLSM) with a topological term.

description: “Somos libres, seámoslo siempre” son las palabras que en el Himno Nacional del Perú —escrito por José de la Torre Ugarte y musicalizado por José Bernardo Alzedo en 1821— cantan a la libertad, la igualdad, la felicidad y la unión; palabras que, no pocas veces en los convulsionados últimos años del país, se hace necesario recordar y reafirmar. Estando tan cerca del bicentenario de la independencia, entrevistamos al historiador Eduardo Torres Arancivia sobre la música que acompañó los primeros años de la fundación de la república. Con la rigurosidad que lo caracteriza, el doctor Torres Arancivia nos ofrece valiosos aportes acerca de un tema poco estudiado desde la Historia: el contexto, el poder emotivo y la importancia que tuvo la música en la promesa de construcción de la nación en el Perú.
description: The lyrics of the Peruvian national anthem —written by José de la Torre Ugarte and musicalized by José Bernardo Alzedo in 1821— sing to freedom, equality, happiness and unity. “We are free, let us always be” are words that we need to remember and reaffirm frequently, especially during times of social and political turmoil. Approaching the bicentennial of the independence of the country, we interviewed Historian Eduardo Torres Arancivia about the music that accompanied the first years of the novel republic. With his characteristic rigor, Torres Arancibia offers us a valuable contribution on a little-studied subject: the context, the emotional power and the importance that music had within the promise of nation-building in Peru.

description: A Cauchy-characteristic initial value problem for the Einstein-Klein-Gordon system with spherical symmetry is presented. Initial data are specified on the union of a space-like and null hypersurface. The development of the data is obtained with the combination of a constrained Cauchy evolution in the interior domain and a characteristic evolution in the exterior, asymptotically flat region. The matching interface between the space-like and characteristic foliations is constructed by imposing continuity conditions on metric, extrinsic curvature and scalar field variables, ensuring smoothness across the matching surface. The accuracy of the method is established for all ranges of $M/R$, most notably, with a detailed comparison of invariant observables against reference solutions obtained with a calibrated, global, null algorithm.

description: Excavations at Bignor Roman villa between 1985 and 1990, in association with a programme of conservation and repair, investigated various parts of the site including the main baths, the north-east corner of the villa, and the boundaries of both the domestic and farmyard areas. Investigations undertaken on the site of the main baths in 1985, 1987 and 1988 (Part 1 of this report) revealed evidence for occupation prior to the construction of the baths, including the masonry footings for half-timbered and masonry structures, and a sequence of constructional phases not only for the heated rooms and cold plunge bath, but also for the development of the courtyard villa itself As a consequence of the excavations the remains of the cold plunge were restored for display (Appendix 1). Plough-damage assessment excavations in 1985, 1986, 1987 and 1990 (Part 2 of this report) re-established the line of the surrounding wall of the villa, and confirmed that the villa had developed in the 4th century AD from a winged-corridor structure, through a phase where two long lines of rooms flanked the approach to the earlier west wing, to a courtyard building with adjoining outer farmyard. Studies of finds from the 1985-1990 excavations provide additional information about both the economy and material culture of the site. This section of the report also includes a brief study of brick and tile found at Bignor before 1985 (Part 3 of this report).

description: Single-layer transition metal dichalcogenides (TMDs) provide a promising material system to explore the electron's valley degree of freedom as a quantum information carrier. The valley degree of freedom in single-layer TMDs can be directly accessed by means of optical excitation. The rapid valley relaxation of optically excited electron-hole pairs (excitons) through the long-range electron-hole exchange interaction, however, has been a major roadblock. Theoretically such a valley relaxation does not occur for the recently discovered dark excitons, suggesting a potential route for long valley lifetimes. Here we investigate the valley dynamics of dark excitons in single-layer WSe2 by time-resolved photoluminescence spectroscopy. We develop a waveguide-based method to enable the detection of the dark exciton emission, which involves spin-forbidden optical transitions with an out-of-plane dipole moment. The valley degree of freedom of dark excitons is accessed through the valley-dependent Zeeman effect under an out-of-plane magnetic field. We find a short valley lifetime for the dark neutral exciton, likely due to the short-range electron-hole exchange, but long valley lifetimes exceeding several nanoseconds for dark charged excitons.
Mapping the Spatiotemporal Interactions of the Human Brain's Attention Reorienting and Arousal Systems Using Multimodal Recording Techniques

description: The human brain is remarkably good at identifying stimuli worthy of attention, and efficiently allocating its limited neural resources. In the context of an attention reorienting task, where subjects are required to process novel and unexpected incoming sensory information and transform them into actions, the goal for the brain is therefore to orient attention to the most task-relevant stimulus so as to facilitate stimulus processing and behavioral outcome. Recent studies suggest that arousal plays a role in modulating attention reorienting, task engagement, and performance optimization. The rising interest and studies notwithstanding, the exact mechanism and function of arousal in attention reorienting still remains largely elusive. The aim of this dissertation is to investigate the interactions between arousal and attention reorienting systems, and the spatiotemporal dynamics of such interactions. Specifically, we simultaneously record pupillometry, electroencephalography (EEG), and functional magnetic resonance imaging (fMRI) to study the fluctuations of the latent states, while subjects perform an auditory oddball task. The oddball task is used to drive the attention reorienting response, and to control for potential ocular confounds that might be induced with a visual paradigm. With concurrently recorded cross modality data, we explore different aspects of the potential interactions between arousal and attention reorienting systems using various combinations of modality-specific trial-to-trial variabilities. We find baseline pupil-linked arousal is correlated to EEG variability temporally localized at a time after the behavioral response, and spatially linked to intrinsically-driven and executive-function related regions; whereas stimulus-driven pupil-linked arousal is temporally related to EEG variability closer to the stimulus onset, and spatially correlated to task-relevant regions. Taken together, our work in this dissertation uses innovative data acquisition and analysis approaches to provide a novel spatiotemporal mapping of the interactions between arousal and attention reorienting systems. Our findings offer new insight on the mechanism and function of how human orients attention, and how arousal is linked to such seemingly trivial yet fundamentally significant cognitive function.

description: Lack of understanding of the extension, education, and development practitioners’ role and their contribution to sustainable agriculture is the main challenge of sustainability projects in Iran. Accordingly, the aim of this study was to identify the extension system that has been more successful in sustainable horticulture. The population consisted of 22 pioneer farmers that had used or are using the services and/or consultations of both public and private extension experts in different ways. Based on census data, 20 farmers were studied. A questionnaire was used to collect the data. To determine the face and content validity, a panel of experts and to assess the reliability, inconsistency ratio was used (IR=0.03). Based on the five sustainability criteria, public extension system was identified as the superior system in the improvement of the sustainability of horticulture activities. Analytical hierarchy process based on the pair-wise comparison and the combination of the relative weights of sub-criteria and options showed that the public system is preferred over the private system, especially in ecological, cultural, and social dimensions. Given the relative superiority of the public extension system over the private extension system, it is recommended to use private extension system along with the public system as a supplementary system so as to gradually pave the way for assigning the authorities and activities to the private sector. Then, we can hope for the full privatization of agricultural education and extension system.

We analyze a NuSTAR observation of the stellar-mass black hole in GS 1354-645, Suzaku data of the supermassive black holes in Ark 564, 1H0419-577, and PKS 0558-504, and some simultaneous XMM-Newton and NuSTAR observations of the supermassive black hole in MCG-6-30-15. All our measurements of $ε_3$ are consistent with the Kerr metric and we find quite strong constraints from Ark 564 and MCG-6-30-15. We discuss the implications of our results and the next steps to improve our tests.

Slag reclamation in the 21st century

description: A plan of action is proposed to develop uses of non-ferrous slag and production of certain industrial materials from this waste material. A review of chemistry of non-ferrous slags suggested that it can be reprocessed to impart "cementitious" properties and furthermore an advantage could be taken of their latent "pozzolonaic" properties to test several potential applications such as - clinker ingredient, asphalt concrete additive, cemented mine backfill and binder for base stabilization. The authors note that in the last century blast furnace slag was considered as a "waste" product whose stocks grew at an alarming rate due to decades of accumulation and iron producers had to develop uses of this material to avoid a potentially catastrophic environmental situation. Non-ferrous slag producers could emulate this example set by the iron producers who successfully converted a "waste" into a "byproduct". Environmental concerns of the new millennium demand that the industry should find ways and means of depleting the ever-growing stockpiles of non-ferrous slag. The authors conclude that serious considerations from environmental and economic fronts favor reclamation of old slag dumps as well as processing of new non-ferrous slag as a viable alternative to the existing dumping practice.

description: Sustainable Livelihoods Approach emerged in the 1980s as a new analytical approach in the field of rural development in which the rural livelihood capitals form the basis of the villagers' empowerment and their ability to get involved in their own individual and social destiny. This study aimed to answer the question that how much the importance of each type of livelihood capitals is in the Central District of Dena County in an attempt to improve rural development interventions. The statistical population of the study consisted of local experts of Central District of Dena County that involved village managers and village council members out of which 15 individuals were purposefully selected based on their accessibility. Data were collected through a questionnaire which was developed to conduct pairwise comparisons of livelihood capitals according to the ANP method. Super Decisions software was used in order to rank livelihood capitals and their sub-indexes. The results showed that from among the five types of capital, physical capital was at the first priority. In addition, human, natural and social capitals were at the second, third and fourth priorities, respectively. Finally, financial capital was in the last priority. Therefore, in planning and investing to achieve sustainable livelihood in rural areas, physical and human capital should be taken into consideration more than any other capitals.

Orbital-selective bad metals due to Hund's rule and orbital anisotropy: a finite-temperature slave-spin treatment of the two-band Hubbard model

description: We study the finite-temperature properties of the half-filled two-band Hubbard model in the presence of Hund's rule coupling and orbital anisotropy. We use the mean-field treatment of the $Z_2$ slave-spin theory with a finite-temperature extension of the zero-temperature gauge variable previously developed by Hassan and de' Medici http://dx.doi.org/10.1103/PhysRevB.81.035106}{Phys. Rev. B {\bf 81}, 035106 (2010)}]. We consider the instability of the Fermi liquid phases and how it is enhanced by the Hund's rule. We identify paramagnetic solutions that have zero quasi-particle weight with bad metallic phases, and the first-order transition temperature between it and the Fermi liquid phase as a coherence temperature that signals the crossover to the bad metallic state. When orbital anisotropy is present, we found an intermediate transition to an orbital-selective bad metal (OSBM), where the narrow band becomes a bad metal while the wide band remains a renormalised Fermi liquid. The temperatures $T_\textrm{coh}$ and $T_\textrm{OSBM}$ at which the system transitions to the bad metal phases can be orders of magnitude less than the Fermi temperature associated with the non-interacting band. The parameter dependence of the temperature at which the OSBM is destroyed can be understood in terms of a ferromagnetic Kondo-Hubbard lattice model. In general, Hund's rule coupling enhances the bad metallic phases, reduce interorbital charge fluctuations and increase spin fluctuations. The qualitative difference found in the ground state whether the Hund's rule is present or not, related to the degeneracy of the low energy manifold, is also maintained for finite temperatures.

description: We study the three-dimensional generalized six-state clock model at values of the energy parameters, at which the system is considered to have the same behavior as the stacked triangular antiferromagnetic Ising model and the three-state antiferromagnetic Potts model. First, we investigate ordered phases by using the Monte Carlo twist method (MCTM). We confirmed the existence of an incompletely ordered phase (IOP1) at intermediate temperature, besides the completely ordered phase (COP) at low-temperature. In this intermediate phase, two neighboring states of the six-state model mix, while one of them is selected in the low temperature phase. We examine the fluctuation the mixing rate of the two states in IOP1 and clarify that the mixing rate is very stable around 1:1. The high temperature phase transition is investigated by using non-equilibrium relaxation method (NERM). We estimate the critical exponents beta=0.34(1) and nu=0.66(4). These values are consistent with the 3D-XY universality class. The low temperature phase transition is found to be of first-order by using MCTM and the finite-size-scaling analysis.

description: Semi-local approximations to the density functional for the exchange-correlation energy of a many-electron system necessarily fail for lobed one-electron densities, including not only the familiar stretched densities but also the less familiar but closely-related noded ones. The Perdew-Zunger (PZ) self-interaction correction (SIC) to a semi-local approximation makes that approximation exact for all one-electron ground- or excited-state densities and accurate for stretched bonds. When the minimization of the PZ total energy is made over real localized orbitals, the orbital densities can be noded, leading to energy errors in many-electron systems. Minimization over complex localized orbitals yields nodeless orbital densities, which reduce but typically do not eliminate the SIC errors of atomization energies. Other errors of PZ SIC remain, attributable to the loss of the exact constraints and appropriate norms that the semi-local approximations satisfy, and suggesting the need for a generalized SIC. These conclusions are supported by calculations for one-electron densities, and for many-electron molecules. While PZ SIC raises and improves the energy barriers of standard generalized gradient approximations (GGA's) and meta-GGA's, it reduces and often worsens the atomization energies of molecules. Thus PZ SIC raises the energy more as the nodality of the valence localized orbitals increases from atoms to molecules to transition states. PZ SIC is applied here in particular to the SCAN meta-GGA, for which the correlation part is already self-interaction-free. That property makes SCAN a natural first candidate for a generalized SIC.

description: This work develops a marginal screening test to detect the presence of significant predictors for a right-censored time-to-event outcome under a high-dimensional accelerated failure time (AFT) model. Establishing a rigorous screening test in this setting is challenging, not only because of the right censoring, but also due to the post-selection inference. The oracle property in such situations fails to ensure adequate control of the family-wise error rate, and this raises questions about the applicability of standard inferential methods. McKeague and Qian (2015) constructed an adaptive resampling test to circumvent this problem under ordinary linear regression. To accommodate right censoring, we develop a test statistic based on a maximally selected Koul--Susarla--Van Ryzin estimator from a marginal AFT model. A regularized bootstrap method is used to calibrate the test. Our test is more powerful and less conservative than the Bonferroni correction and other competing methods. This proposed method is evaluated in simulation studies and applied to two real data sets.

In particular, our model provides examples of blowout bifurcations that occur on varying a non-normal parameter; that is, the parameter varies the dynamics within the invariant subspace at the same time as the dynamics normal to it. As a consequence of this we find that the Lyapunov exponents do not vary smoothly and the blowout bifurcation occurs over a range of parameter values rather than a point in the parameter space.

description: The null-surface formulation of general relativity -- recently introduced -- provides novel tools for describing the gravitational field, as well as a fresh physical way of viewing it. The new formulation provides ``local'' observables corresponding to the coordinates of points --- which constitute the spacetime manifold --- in a {\em geometrically defined chart\/}, as well as non-local observables corresponding to lightcone cuts and lightcones. In the quantum theory, the spacetime point observables become operators and the spacetime manifold itself becomes ``quantized'', or ``fuzzy''. This novel view may shed light on some of the interpretational problems of a quantum theory of gravity. Indeed, as we discuss briefly, the null-surface formulation of general relativity provides (local) geometrical quantities --- the spacetime point observables --- which are candidates for the long-sought physical operators of the quantum theory.

Progressive reclamation utilizing biosolids at the Hedley Gold Tailings Project, Hedley, British Columbia, Canada
Creators: name: Horton, Russ

Publisher: name: The University of British Columbia
Year: 2009

description: The Hedley Gold Tailings Project was a heap leach gold extraction mine that operated between 1988 and 1995 beside Hedley, British Columbia. Tailings from the historic Mascot and Giant Nickel mines were deposited to the north and southeast of Hedley between 1904 and 1955. These tailings were mined, agglomerated, stacked into a heap and leached for gold, most recently by Candorado Operating Company Ltd. The Greater Vancouver Regional District progressively reclaimed some of the disturbed tailings areas in three phases during 1996, 1997 and 2000 utilizing biosolids. Forage establishment with biosolids was successful for all reclaimed tailings areas, improving their aesthetics and dust control. Public consultation was integral to each reclamation phase that utilized biosolids. Effective collaboration between public agencies enabled successful execution of the third phase. Continued reclamation progress at this site has demonstrated the value of public consultation and the capacity for collaboration between public agencies to enable progressive reclamation for the common good at a financially constrained mine site.

description: This report describes a small motte apparently built in the 13th century. After temporary occupation the top was heightened and a light palisade may have surrounded the motte top at that time. Impressions of crosstrees were found in the centre, presumably for some structure above. Finds favour, but do not prove convicingly, this is a windmill base c.1700. Alternatively, the crosstreees might represent the base of a small central tower or look-out platform put up in the 13th century.

Marine thorium and protactinium distributions: Tools for past and present chemical flux

description: Adsorption to sinking particulate matter, known as scavenging, is an important yet elusive term in the budgets of many bioactive and contaminant trace metals in the ocean. Scavenging is also involved in the cycling of other trace metals used in ocean sediments to learn about ocean processes, such as circulation rates or biological productivity, of the geologic past. This dissertation is an oceanographic exploration of the naturally-occurring radionuclides 230Th, 232Th and 231Pa aimed to better understand how their scavenging behavior can be utilized to trace chemical flux in the modern and the past ocean. While 230Th and 231Pa are produced by the radioactive decay of uranium dissolved in seawater, 232Th is added to the ocean via the input of continental material. Removal of Th by scavenging should be equivalent for both Th isotopes based on chemical principles. I use measured 232Th inventories from the North Pacific water column and apply a removal rate based on 234U:230Th disequilibria to estimate the flux of dissolved trace elements, such as the micro-nutrient Fe, to the ocean through the deposition of mineral dust (Chapter 2). Results from this study also raise the possibility of differing chemical behavior of the two Th isotopes in shallow water (<500 m depth) related to size-partitioning between truly dissolved and colloidal phases. Finally, results from the U.S. GEOTRACES North Atlantic Transect are used to investigate the relationship between 231Pa and 230Th in the water column and several of their proposed paleoceanographic purposes. The accuracy of 230Th as a proxy for constant sediment flux can be directly quantified to 40±10% with observations of boundary scavenging near the coast of Northwest Africa (Chapter 4). The 231Pa/230Th ratio in the water column is not clearly controlled by either ocean ventilation (Chapter 4) or particle composition (Chapter 5) alone. Near-bottom enhanced scavenging of both isotopes is also occurring over large regions, in benthic layers of resuspended sediments and in a hydrothermal plume emanating from the mid-Atlantic ridge. These novel observations must be reconciled in a new conceptual model, likely requiring future numerical modeling work, in order to clarify the use of the 231Pa/230Th ratio as a proxy for the Atlantic meridional overturning circulation.

description: The waste of agricultural products is considered as one of the major problems in Iranian agricultural sector. The present study is a descriptive-survey that focused on exploring correlations and comparison. Data were collected through a research made questionnaires and were analyzed by SPSS. The relationships between dependent and independent variables were analyzed by obtaining the Pearson's correlation coefficient. The statistical population of the study comprised the participants of vermicompost training courses in 2011-12, farmers of Estalkh Zir Village where the vermicompost project was implemented, and facilitators and promoters of the agricultural sector. The results showed that there was a relationship between the dependent (familiarity, the skills and interest rate) and independent variables (agricultural waste management) and that it was confirmed p<0.05) that the impact of the four independent variables was significant on the dependent variable at 0.05 level. As a result, all factors as independent variables are believed to have contributed to waste management. Duncan’s test also indicated that there was a significant difference in terms of waste management among the existing factors, namely interest rate, levels of familiarity and awareness, skills, and support from authorities.
