description: Fluid through fractures is important in many natural and industrial settings, e.g. enhanced geothermal systems (EGS). This experimental study, performed within the framework of the European Union's Horizon 2020 initiative 'MEET (Multi-Sites EGS Demonstration)', presents fracture permeability results from intermittent flow-through tests performed on saw-cut slate samples from the Hahnenklee drill site, Harz mountains, Germany, used as an analogue for EGS reservoir formations within Variscan metamorphic rocks. The surface roughness (Sa, arithmetical mean deviation ) of the artificial fracture was 0.109mm and 0.075mm, respectively, determined by 3D laser scanning confocal microscopy. As a baseline measurement, we applied conditions of 70°C temperature, 10MPa confining pressure and 1MPa pore pressure using distilled water as pore fluid, which were kept constant during the entire test period of 30 days. A pronounced permeability reduction by approximately 50% was observed immediately after temperature was increased from ambient to 70°C, indicating that temperature plays a significant role in fracture closure of the investigated slate. However, subsequent permeability change with time at 70°C was negligible although significant amounts of Na+ (23 mg/L) and Si4+ (4 mg/L), originating from dissolution of the rock's minerals, were detected in the pore fluid, acquired during successive flow stagnation of 5 days each and analyzed using inductively coupled plasma optical emission spectrometry (ICP-OES). Our first results suggest that the fracture permeability of the studied rock samples at temperatures relevant for fluid injection into low enthalpy geothermal reservoirs is likely insensitive to mineral dissolution at short time scale. Additional investigations are being carried out to evaluate the effects of time, surface roughness, pore fluid composition, and temperature on the evolution of fracture aperture. Ultimately, this study will help to predict the sustainability of fracture permeability in slate dominated metamorphic EGS reservoirs.

From ATM to MPLS and QCI: The Evolution of Differentiated QoS Standards and Implications for 5G Network Slicing

description: The networking community continues to create new technologies and update existing ones to improve the quality, reliability, and "tailorability" of data networks. However, whenever Internet service providers attempt to productize "tailorability" and sell it explicitly to end customers as a premium service over best effort connectivity, they either fail to overcome net neutrality concerns or struggle to gain market traction. For this article, we focus only on those networking protocols, technologies, or standards whose goal is to offer tailored connectivity to paying customers on a public network and refer to them as differentiated QoS (D-QoS) standards. This article makes two contributions. First, it explores the techno-economic market trajectory of D-QoS standards to understand the factors that determine success. In doing this, we acknowledge that while there is wide variation and dissimilarity in their underlying technical properties, the expectation and goal for all D-QoS standards is that they will be used to provide guaranteed connection for which customers could be prepared to pay. As such, we consider Layer 2/3 technologies (e.g., ATM, frame relay, MPLS), signaling technologies (e.g., RSVP), data packet markers (e.g., IP ToS, DiffServ, WME, QCI), and end-to-end separation solutions (e.g., leased lines, network slicing) as a single cohort and analyze them together. Second, by exploring the parallels with 5G network slicing, we argue that despite its inherent technical differences with other D-QoS standards, the commercial performance of network slicing may end up resembling that of previous D-QoS standards. Consequently, we seek to learn lessons from previous D-QoS attempts and suggest that enterprise-focused 5G slices, running within a single service provider's domain and with binding service level agreements, will have the highest chance of success in the short/medium term.

title: Causation and climate change litigation: ‘bridge too far’?
Creators: name: Wilde, Mark
Publisher: name: Universität Graz
Year: 2021

description: The phenomenon of ‘climate change litigation’ has come to the fore in recent years as campaigners and activists have become increasingly frustrated at a perceived lack of action on the part of the international community and individual states in terms of getting to grips with the climate change problem. Existing legal mechanisms available to private parties and other bodies, such as non-governmental organizations (NGOs) have been used as a means of endeavouring to hold governments and polluters to account for the effects of climate change. The physical impact of climate change on life and property has been thrown into sharp relief by floods and wildfires in all parts of the globe. One aspect of climate change litigation focuses on the role that tort might play in attempting to secure compensation for at least part of such losses. No one would pretend that actions of this nature can actually solve the problem, but they may serve to shame polluters and so forth by establishing an actual link between their activities and the tangible consequences of climate change. However, such actions raise formidable causation difficulties which have, until recently, rendered such claims outlandish and highly speculative. Nevertheless, developments in extreme weather event attribution may be about to reduce the conceptual and theoretical barriers to bringing such claims. In this article it is argued that, from a UK perspective, existing causality tests may be capable of accommodating such evidence, although, one must be aware of countervailing policy considerations which may inhibit the courts from adopting such an approach.

description: We studied the pure and dilute Baxter-Wu (BW) models using the Wang-Landau (WL) sampling method to calculate the Density-Of-States (DOS). We first used the exact result for the DOS of the Ising model to test our code. Then we calculated the DOS of the dilute Ising model to obtain a phase diagram, in good agreement with previous studies. We calculated the energy distribution, together with its first, second and fourth moments, to give the specific heat and the energy fourth order cumulant, better known as the Binder parameter, for the pure BW model. For small samples, the energy distribution displayed a doubly peaked shape. Finite size scaling analysis showed as expected reciprocal scaling of the positions of the peaks with L. The energy distribution yielded the expected $α=2/3$ critical exponent for the specific heat. The Binder parameter minimum appeared to scale with lattice size L with an exponent $θ_B$ equal to the specific heat exponent. Its location (temperature) showed a large correction-to-scaling term $θ_1=0.248\pm 0.025$. For the dilute BW model we found a clear crossover to a single peak in the energy distribution even for small sizes and the expected $α=0$ was recoverd.

description: A particle-in-cell (PIC) simulation study is performed to investigate the discharge asymmetry, higher harmonic generations and electron heating mechanism in a low pressure very high frequency capacitively coupled plasma (CCP) excited by a saw-tooth like current waveform. Two current densities, 50 A/m2 and 100 A/m2 are chosen for a constant gas pressure of 5 mTorr in argon plasma. The driving frequency is varied from 13.56 MHz to 54.24 MHz. At a lower driving frequency, high frequency modulations on the instantaneous sheath edge position at the grounded electrode are observed. These high frequency oscillations create multiple ionization beam like structures near to the sheath edge that drives the plasma density in the discharge and responsible for discharge/ionization asymmetry at lower driving frequency. Conversely, the electrode voltage shows higher harmonics generation at higher driving frequencies and corresponding electric field transients are observed into the bulk plasma. At lower driving frequency, the electron heating is maximum near to the sheath edge followed by electron cooling within plasma bulk, however, alternate heating and cooling i.e. burst like structures are obtained at higher driving frequencies. These results suggest that electron heating in these discharges will not be described accurately by simple analytical models.

description: In a competitive market with free information flows, spatial arbitrage will ensure that average prices at geographically separate markets will move in unison. The speed of adjustment is related to information flows between markets; if adjustment lags exist, there may be opportunities for arbitragers to gain. The transmission of price information is modelled using Johansen's procedure and the existence of long-run arbitrage opportunities is investigated. An innovation analysis is used to examine the varying responses to changes in prices at spatially separate markets.

description: We present a time-resolved optical study of the dynamics of carriers and phonons in Ga_{1-x}Mn_{x}As layers for a series of Mn and hole concentrations. While band filling is the dominant effect in transient optical absorption in low-temperature-grown (LT) GaAs, band gap renormalization effects become important with increasing Mn concentration in Ga_{1-x}Mn_{x}As, as inferred from the sign of the absorption change. We also report direct observation on lattice vibrations in Ga1-xMnxAs layers via reflective electro-optic sampling technique. The data show increasingly fast dephasing of LO phonon oscillations for samples with increasing Mn and hole concentration, which can be understood in term of phonon scattering by the holes.

description: Game theory offers an alternative approach to standard means of resource assessment which can be of value in the definition and assessment of policy options for competing parties. Using a Nash co-operative game it has been possible in this paper to show the significance of fishing strategies for southern bluefin tuna which take into account the age distribution of the catch. Assuming Japan and Australia act according to a cooperative game then the optimal fishing strategy was found to involve Australia avoiding the fishing of the very young cohorts and Japan taking a moderate catch in subsequent older age classes but not the oldest of the age classes. Sub-optimal strategies were also presented and evaluated along with an indication of the level of biomass associated with different strategies. It was concluded that harvesting policies need to be developed both according to weight of fish harvested and age class.
Short study of the eta-eta' system in the two mixing angle scheme

description: A two mixing angle description of the pseudoscalar decay constants associated to the $η$-$η^\prime$ system is used to parametrize the theoretical amplitudes of the radiative decays $(η,η^\prime)\toγγ$ and the coupling constants $g_{V(η,η^\prime)γ}$ with $V=ρ,ω,ϕ$. The parametrization is performed in both the ``octet-singlet'' basis and the ``quark-flavour'' basis. An excellent agreement with the most recent experimental data is achieved. Our analysis reveals that at the present experimental accuracy the two mixing angles differ significantly in the former basis but not in the latter, in accordance with the expectations of large $N_c$ Chiral Perturbation Theory where the difference between the two mixing angles are due to a $SU(3)_f$-breaking effect and a violation of the OZI rule respectively.

EVALUATING LONG-LIVED PROJECTS: THE ISSUE OF INTER-GENERATIONAL EQUITY

Year: 1992
Subjects: Institutional and Behavioral Economics

description: The role of the discount rate in benefit-cost analysis is reviewed, and its impact considered. A positive rate clearly 'tilts the balance overwhelmingly against generations in the distant future'. In this context, the issue of inter-generational equity is discussed, and it is concluded that although a positive rate representing social time preference or opportunity cost is appropriate when considering questions of economic efficiency, this is not the case when equity questions are being examined. In the case of irreversible change, an extreme example of inter-generational inequity, there may be no alternative to a constrained optimisation approach, where the constraint is determined by an ethical decision. A range of approaches for analysing the issue of inter-generational equity are canvassed and it is concluded that efficiency and equity questions need to be dealt with separately. If the analysis of the options on each issue are set out clearly, then policy makers will be better placed to make an informed and responsible decision.

Light propagation in curved spacetime backgrounds is discussed using the geometrical-optics approximation. The corresponding light path is modified, which allows for new effects. In a Schwarzschild background, for example, there now exist stable bounded orbits of light rays and the two polarization modes of light rays in unbounded orbits can have different gravitational redshifts. An Erratum with important corrections has been published, which appears as Appendix E in this arXiv version.

description: The presence or absence of structural change in meat demand is critical to marketing decision making.

description: Trade actions, which can generally be claimed as trade wars, appear to be on the rise. This is particularly true in the case of agricultural commodities. It is a common perception that large countries will be the victors in such contests and this clearly affects the trade strategies of small countries, including Australia. The relationship between free-trade and trade-war pay-offs in the context of a prisoner's dilemma is explored in this paper. It is shown why neither a favourable terms of trade movement, a flatter import demand curve nor a larger population is, on its own, a sufficient condition for a relative victory in a trade war. The implications for small country trade strategies are then discussed.

description: The fiducial coincides with the posterior in a group model equipped with the right Haar prior. This result is here generalized. For this the underlying probability space of Kolmogorov is replaced by a $σ$-finite measure space and fiducial theory is presented within this frame. Examples are presented that demonstrate that this also gives good alternatives to existing Bayesian sampling methods. It is proved that the results provided here for fiducial models imply that the theory of invariant measures for groups cannot be generalized directly to loops: There exist a smooth one-dimensional loop where an invariant measure does not exist.

description: Magnetic fields in red giant stars remain a poorly understood topic, particularly in what concerns their intensity in regions far below the surface. In this work, we propose that gravity-dominated mixed modes of high absolute radial order and low angular degree can be used to probe the magnetic field in their radiative cores. Using two poloidal, axisymmetric configurations for the field in the core and the classical perturbative approach, we derive an analytical expression for the magnetic frequency splitting of these oscillation modes. Considering three distinct red giant models, with masses of 1.3\(M_\odot\), 1.6\(M_\odot\) and 2.0\(M_\odot\), we find that a field strength of $10^5$ G is necessary in the core of these stars to induce a frequency splitting of the order of a $μ$Hz in dipole and quadrupole oscillation modes. Moreover, taking into account observational limits, we estimate that magnetic fields in the cores of red giants that do not present observable magnetic splittings cannot exceed $10^4$ G. Given the general absence of observable splittings in the oscillation spectra of these stars, and assuming that present mode suppression mechanisms are not biased towards certain azimuthal orders and retain all peaks in each multiplet, our results lead us to conclude that internal fields with the considered configurations and strengths above $10^4$ G are not prevalent in red giants.

description: User-provided multi-aspect evaluations manifest users' detailed feedback on the recommended items and enable fine-grained understanding of their preferences. Extensive studies have shown that modeling such data greatly improves the effectiveness and explainability of the recommendations. However, as ranking is essential in recommendation, there is no principled solution yet for collectively generating multiple item rankings over different aspects. In this work, we propose a directional multi-aspect ranking criterion to enable a holistic ranking of items with respect to multiple aspects. Specifically, we view multi-aspect evaluation as an integral effort from a user that forms a vector of his/her preferences over aspects. Our key insight is that the direction of the difference vector between two multi-aspect preference vectors reveals the pairwise order of comparison. Hence, it is necessary for a multi-aspect ranking criterion to preserve the observed directions from such pairwise comparisons. We further derive a complete solution for the multi-aspect ranking problem based on a probabilistic multivariate tensor factorization model. Comprehensive experimental analysis on a large TripAdvisor multi-aspect rating dataset and a Yelp review text dataset confirms the effectiveness of our solution.

description: The angular momentum of a classical electromagnetic plane wave of arbitrary extent is predicted to be, on theoretical grounds, exactly zero. However, finite sections of circularly polarized plane waves are found experimentally to carry angular momentum and it is known that the contribution to the angular momentum arises from the edges of the beam. A mathematical model is described that gives a quantitative account of this effect and resolves the paradox.

description: Blarney, Common and Quiggin (1995) (BCQ) suggest that responses to contingent valuation (CV) questionnaires may be framed either according to the extent of individual benefits received, or according to wider views about ethical frameworks, impacts on other people, or desired societal levels. They characterise the individual benefit approach as a consumer model, and responses indicating wider concerns as citizen preferences. Citizen value responses are held to invalidate the economic assumptions underlying the use of CV. Hence, they hypothesize that the incorporation of CV results into benefit-cost analysis is problematic. In this comment we suggest that there are several flaws with the citizen value hypothesis. These can be grouped into arguments about the existence of citizen values based on ethical or altruistic grounds, and arguments about the identification of citizen values.

description: Non-compensatory preferences may form a significant component of individuals' values for non-market goods such as natural areas, especially in the context of a reduction in environmental quality. The widespread neglect of such preferences can result in erroneous estimates of changes in economic welfare. Non-market valuation using techniques such as contingent valuation therefore need to take into account the possibility that some individuals hold noncompensatory preferences. The formal structure of the lexicographic noncompensatory ordering is described, and the theoretical implications of an individual holding such preferences over some region of goods space is examined. A method for the empirical identification of non-compensatory preference orderings is outlined.

description: The agricultural production of Indian farmers is investigated using a stochastic frontier production function which incorporates a model for the technical inefficiency effects. Farm-level data from the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) are used. Variables considered in the model for the inefficiency effects include the age and level of education of the farmers, farm size and the year of observation. The parameters of the stochastic frontier production function are estimated simultaneously with those involved in the model for the inefficiency effects. This approach differs from the usual practice of predicting farm-level inefficiency effects and then regressing these upon various factors in a second-stage of modelling. The results indicate that the above factors do have a significant influence upon the inefficiency effects of farmers in two of the three villages considered.

description: This narrative multiple-case study explored and described the meaning of intrusions to five individuals who had experienced trauma and the meaning of intrusions in their experience of trauma recovery. The participants included two men and three women, ranging in age from 26 to 71 years old. This was a cross-trauma investigation as the participants had experienced different traumatic stressors and the time elapsed posttrauma ranged from 2 1/2 to 25 years. Three had experienced chronic or prolonged traumatic exposure for an average of twenty years. Two had experienced sudden and unexpected events in which they were seriously injured and their lives were in danger. The chronic traumatic experiences included; childhood exposure to violence in the family home and foster care, childhood sexual abuse by a volunteer mentor and degenerative illness from beast implant silicone toxicity. The acute traumatic experiences included a serious motor vehicle accident and a direct lightning strike to a participant's body. Three types of intrusions were identified in the study; re-living phenomena, intrusions related to the practical issues and implications of the trauma and those involved in an existential search for meaning. The findings also showed that intrusions are related to unresolved issues of the person and that intrusions evolved. Specific intrusions ended when the issue that the intrusion illumined was resolved. The study illustrated the processes of meaning making that the participants engaged in. The involvement of intrusions in reschematization or the development of posttrauma assumptions has been proposed. Finally, the results of this study illustrated that intrusions have not been accurately defined and are more than re-experiencing phenomena. The identification of three types of intrusions challenges the validity of current assessment instruments and has implications for the practice of trauma therapy.

On the Probabilistic Interpretation of the Evolution Equations with Pomeron Loops in QCD

description: We study some structural aspects of the evolution equations with Pomeron loops recently derived in QCD at high energy and for a large number of colors, with the purpose of clarifying their probabilistic interpretation. We show that, in spite of their appealing dipolar structure and of the self-duality of the underlying Hamiltonian, these equations cannot be given a meaningful interpretation in terms of a system of dipoles which evolves through dissociation (one dipole splitting into two) and recombination (two dipoles merging into one). The problem comes from the saturation effects, which cannot be described as dipole recombination, not even effectively. We establish this by showing that a (probabilistically meaningful) dipolar evolution in either the target or the projectile wavefunction cannot reproduce the actual evolution equations in QCD.

description: The demand for high quality hard wheats has been increasing. In this paper, factors affecting the supply and consistency of high quality wheats in Canada and North Dakota were compared and contrasted. Differences exist in the development and release of new varieties which affect the number and quality of hard wheats produced. Variety numbers and concentration were examined with a range of measures. Wheat area in Canada was found to be concentrated in fewer varieties than in North Dakota. These results were more apparent for durum than for hard red spring wheats. However, there was a trend toward more concentration in North Dakota and less in Canada. Protein, yield, and trade-offs were compared. Alberta appears to have a comparative advantage in the production of higher protein wheats. Farmers there have less of a yield loss penalty for increasing protein, compared to other regions. Varietal selection models were developed to analyze factors affecting variety choice. In Canada, agronomic factors including, relative yields, were significant variables affecting variety choice. In North Dakota, agronomic factors other than years since release generally had less effect on adoption rates. Varieties in North Dakota and Manitoba were found to have shorter life cycles and reached their maximum utilization by farmers faster than in Alberta or Saskatchewan.

description: The rotation curve for the IV galactic quadrant, within the solar circle, is derived from the Columbia University - U. de Chile CO(J=1-0) survey of molecular gas. A new sampling, four times denser in longitude than in our previous analysis, is used to compute kinematical parameters that require derivatives w/r to galactocentric radius; the angular velocity Omega(R), the epicyclic frequency kappa(R), and the parameters A(R) and B(R) describing, respectively, gas shear and vorticity. The face-on surface density of molecular gas is computed from the CO data in galactocentric radial bins for the subcentral vicinity, the same spectral region used to derive the rotation curve, where the two-fold ambiguity in kinematical distances is minimum. The rate of massive star formation per unit area is derived, for the same radial bins, from the luminosity of IRAS point-like sources with FIR colors of UC HII regions detected in the CS(J=2-1) line. Massive star formation occurs preferentially in three regions of high molecular gas density, coincident with lines of sight tangent to spiral arms. The molecular gas motion in these arms resembles that of a solid body, characterized by constant angular velocity and by low shear and vorticity. The formation of massive stars in the arms follows the Schmidt law, Sigma_{MSFR} is proportional to [Sigma_{gas}]^n, with an index of n = 1.2 +- 0.2 Our results suggest that the large scale kinematics, through shear, regulate global star formation in the Galactic disk.

description: Non-volatile memory devices have been limited to flash architectures that are complex devices. Here, we present a unique photomemory effect in MoS$_2$ transistors. The photomemory is based on a photodoping effect - a controlled way of manipulating the density of free charges in monolayer MoS$_2$ using a combination of laser exposure and gate voltage application. The photodoping promotes changes on the conductance of MoS$_2$ leading to photomemory states with high memory on/off ratio. Such memory states are non-volatile with an expectation of retaining up to 50 % of the information for tens of years. Furthermore, we show that the photodoping is gate-tunable, enabling control of the recorded memory states. Finally, we propose a model to explain the photodoping, and we provide experimental evidence supporting such a phenomenon. In summary, our work includes the MoS$_2$ phototransistors in the non-volatile memory devices and expands the possibilities of memory application beyond conventional memory architectures.
Mellin Moments of the Next-to-next-to Leading Order Coefficient Functions for the Drell-Yan Process and Hadronic Higgs-Boson Production

description: We calculate the Mellin moments of the next-to-next-to leading order coefficient functions for the Drell--Yan and Higgs production cross sections. The results can be expressed in terms of multiple finite harmonic sums of maximal weight w = 4. Using algebraic and structural relations between harmonic sums one finds that besides the single harmonic sums only five basic sums and their derivatives w.r.t. the summation index contribute. This representation reduces the large complexity being present in x-space calculations and is well suited for fast numerical implementations.

description: We provide an operator algebraic interpretation of discrete measurable groupoids in the course of re-proving (and slightly generalizing) a result on treeability due to Adams and Spatzier. Then, we reconstruct Gaboriau's beautiful work on costs of equivalence relations in operator algebra framework, avoiding any measure theoretic argument, and clarify what kind of his results can or cannot be generalized to the non-principal groupoid case.

description: Electrically charged solutions for gravity with a conformally coupled scalar field are found in four dimensions in the presence of a cosmological constant. If a quartic self-interaction term for the scalar field is considered, there is a solution describing an asymptotically locally AdS charged black hole dressed with a scalar field that is regular on and outside the event horizon, which is a surface of negative constant curvature. This black hole can have negative mass, which is bounded from below for the extremal case, and its causal structure shows that the solution describes a "black hole inside a black hole". The thermodynamics of the non-extremal black hole is analyzed in the grand canonical ensemble. The entropy does not follow the area, and there is an effective Newton constant which depends on the value of the scalar field at the horizon. If the base manifold is locally flat, the solution has no electric charge, and the scalar field has a vanishing stress-energy tensor so that it dresses a locally AdS spacetime with a nut at the origin. In the case of vanishing selfinteraction, the solutions also dress locally AdS spacetimes, and if the base manifold is of negative constant curvature a massless electrically charged hairy black hole is obtained. The thermodynamics of this black hole is also analyzed. It is found that the bounds for the black holes parameters in the conformal frame obtained from requiring the entropy to be positive are mapped into the ones that guarantee cosmic censorship in the Einstein frame.

description: We conjecture that if C is a curve of genus >1 over a number field k such that C(k) is empty, then a method of Scharaschkin (equivalent to the Brauer-Manin obstruction in the context of curves) supplies a proof that C(k) is empty. As evidence, we prove a corresponding statement in which C(F_v) is replaced by a random subset of the same size in J(F_v) for each residue field F_v at a place v of good reduction for C, and the orders of Jacobians over finite fields are assumed to be smooth (in the sense of having only small prime divisors) as often as random integers of the same size. If our conjecture holds, and if Shafarevich-Tate groups are finite, then there exists an algorithm to decide whether a curve over k has a k-point, and the Brauer-Manin obstruction to the Hasse principle for curves over the number fields is the only one.
