description: Microquasars are galactic black hole binary systems with radio jets which can sometimes be spatially resolved to show superluminal motion. The first and best known of this class of objects is GRS 1915+105, the brightest accreting source in our Galaxy. There is persistent speculation that strong jet emission could be linked to black hole spin. If so, the high spin should also be evident in accretion disc spectra. We search the RXTE archive to find disc-dominated X-ray spectra from this object, as these are the only ones which can give reliable spin determinations by this method. Finding these is complicated by the rapid, unique limit cycle variability, but we are able to identify such spectra by going to the shortest possible time resolution (16 s). We fit them with a simple multicolour disc blackbody diskbb, and with the best current model which include full radiative transfer as well as relativistic effects bhspec. Both these models show that the spin is intermediate, neither zero nor maximal. bhspec, the most physical model, gives a value for the dimensionless spin of a* \~ 0.7 for a distance of 12.5 kpc and inclination of 66 deg. This, together with the range of spins 0.1 < a* < 0.8 derived using this method for other black holes, suggests that jet emission is probably fundamentally powered by gravity rather than spin, and implies that high-to-maximal spin is not a pre-requisite for powerful relativistic jets.

description: Context: Land use change requires measuring shifting patterns in biodiversity at various spatial scales to inform landscape management. Assessing vegetation change at different scales is challenging in urban ecosystems managed by many individuals. Thus, we do not know much about the structure and function of green spaces that support biodiversity. Objective: We aim to understand how vegetation structure and function indicators in urban community gardens vary with spatial scale, applying new and traditional methods in landscape ecology to inform future research and application. Methods: We performed two methods to assess garden vegetation structure (height) and function (species diversity, cover) at the garden- and garden plot scale. First, we used traditional field sampling to estimate garden vegetation at the garden scale (1 m 2 quadrats along transects) and at the plot scale (estimated within entire plot) to measure height, diversity and cover. Second, we used UAV aerial imagery to derive measures of garden and plot vegetation using canopy height models (CHMs). We evaluated differences in CHMs at each scale across the gardens, and compared field and UAV-derived measures. Results: Garden vegetation characteristics vary with spatial scale. Plant species richness and vegetation cover, but not height, related to UAV-derived imagery. Conclusions: New technologies paired with traditional field methods can together inform how vegetation structure and function vary with spatial scale in urban landscapes. Spatial scale is key to accurate and meaningful urban vegetation analyses. New and traditional methods in urban ecology research should develop together to improve and streamline their future application.

description: Two dozens of different mass galaxies observed at distances less than 10 Mpc from the Local Group are organized in the elongated structure known as the Sculptor Filament. We use recent Hubble Space Telescope data on local galaxies to study the dynamical structure and evolutionary trends of the filament. An N-body computer model, which reproduces its observed kinematics, is constructed under the assumption that the filament is embedded in the universal dark energy background. In the model, the motions of the filament members are controlled by their mutual gravity attraction force and the anti-gravity repulsion force produced by the local dark energy. It is found that the dark energy repulsion dominates the force field of the outer parts of the filament. Because of this, the filament expands and its expansion proceeds with acceleration. The dark energy domination increases with cosmic time and introduces to the filament the linear velocity--distance relation with the universal time-rate ("the Hubble constant") that depends asymptotically on the dark energy density only.

description: Privatisation of animal healthcare systems in developing countries, particularly in sub-Saharan Africa, has had very limited success. Introduced with inadequate transition time and too few resources, many livestock owners either cannot afford or, just as likely, are unable to gain access to the services they need. Poor livestock owners in remote rural areas suffer the greatest disadvantage. This fact is undisputed but, since privatisation, the primary focus has been on analysing the performance of animal healthcare systems and few authors have studied the underlying economic theories that have driven privatisation policy nor examined in what ways these may have been detrimental. This working paper examines how the economic analysis of animal health services has evolved since the '90s. A comparison is made with economic theories underlying the provision of human healthcare services where the debate started much earlier (in the '60s). Special emphasis is put on how these perspectives have influenced privatisation policy and, in particular, based in general economic literature, how the way in which 'public goods' is defined affects their financing and provision. Following this perspective, the role that governments should expect to play in the animal healthcare sector post privatisation is also debated. A relatively new approach to the economic analysis of animal health services is therefore presented, one that has been propounded recently by a number of economists working in this field. This economic theory, based on the perspective of 'public choice' argues that the process of decision-making may be highly significant in influencing efficiency and effectiveness. Traditional 'outcome' analysis omits factors such as self-interested behaviour and political interference. These may have contributed to higher than expected 'transaction' costs and, therefore, to the failure in many instances of the privatisation process. Given that much greater attention than in the past should be paid to issues of governance, governments in future may expect to act not only as external agents with regulatory power but as part of the nation's animal healthcare system with responsibility for defining overall goals and harmonising and facilitating the market economy.

Political Economy

description: This paper presents a case study of how livestock policies are made and implemented in a national context, and how they can be improved to better serve the interests of the poor in Cambodia. Opportunities exist for improving rural livelihoods in Cambodia through the export of livestock. While Cambodia claims little of the official export market for cattle, huge demand exists within the region and beyond. Three strategic entry points are recommended that can both improve the performance of the sector and the participation of the poor in productive activities.
Cepstral Analysis for Baseline-Insensitive Absorption Spectroscopy Using Light Sources with Pronounced Intensity Variations

description: This manuscript presents a data-processing technique which improves the accuracy and precision of absorption-spectroscopy measurements by isolating the molecular absorbance signal from errors in the baseline light intensity (Io) using cepstral analysis. Recently, cepstral analysis has been used with traditional absorption spectrometers to create a modified form of the time-domain molecular free-induction decay (m-FID) signal which can be analyzed independently from Io. However, independent analysis of the molecular signature is not possible when the baseline intensity and molecular response do not separate well in the time domain, which is typical when using injection-current-tuned lasers (e.g., quantum cascade lasers) and other light sources with pronounced intensity tuning. In contrast, the method presented here is applicable to all light sources since it determines gas properties by least-squares fitting a simulated m-FID signal to the measured m-FID signal in the time domain. This method is insensitive to errors in the estimated Io which vary slowly with optical frequency and, therefore, decay rapidly in the time domain. The benefits provided by this method are demonstrated via scanned-wavelength direct-absorption measurements acquired with a distributed-feedback (DFB) quantum-cascade laser (QCL). The wavelength of a DFB QCL was scanned across CO's P(0,20) and P(1,14) absorption transitions at 1 kHz to measure the gas temperature and concentration of CO. Measurements were acquired in a gas cell and in an ethylene-air flame at 1 atm. The measured spectra were processed using the new m-FID-based method and two traditional methods which rely on inferring the baseline error within the spectral-fitting routine. The m-FID-based method demonstrated superior accuracy in all cases and a measurement precision that was 1.5 to 10 times smaller than that provided using traditional methods.

description: Amphiphilic copolymers with poly (alkyl acrylate) as hydrophobic and poly (acrylic acid) (AA) as hydrophilic block have been synthesised. The alkyl chain was varied from butyl to dodecyl, thereby varying systematically the polarity of the hydrophobic block whose length was between 35 and 70, while the PAA block had ~ 100 units. Such relatively short amphiphiles should equilibrate quickly in aqueous solution, and their corresponding self-assembly properties were characterised by means of critical micelle concentration (cmc) determination. Detailed information regarding the aggregate structures was obtained by static light scattering (SLS) and small angle neutron scattering (SANS). This could be correlated with the molecular architecture of the copolymers and the degree of ionisation of the PAA block. Generally, it is found that the aggregation numbers become smaller upon fully charging the PAA head group and only for dodecyl acrylate really well-defined micellar aggregates are formed. This means that the extent of hydrophobicity of the alkyl acrylate block and its length determine in a clear fashion the propensity for micelle formation and the mass and aggregation number of the formed micelles.
Beauty is in the eye of the beholder : "monster houses" in Vancouver

Publisher: name: University of British Columbia

description: Architectural housing styles have always been items of interest and comment in Vancouver, but recent times have seen new twists to old concerns. In the 1970s houses on Vancouver's East Side were dubbed 'Vancouver Specials'. These houses were described as 'boxy', Tot huggers' and 'ugly'. However, as the issue was relatively an "East Side problem" it was not highly visible in the media or elsewhere in Vancouver society. When large houses, of similar design to the 'Vancouver Specials', began to be built in Vancouver's more affluent and whiter West Side in the 1980s, debate over 'Monster' houses was born. This controversy has continued through to this decade as builders, real estate agents, architects, neighbourhood lobbyists, and city planners debate the "normalcy" of landscape. This thesis considers the ramifications of "urban change" to the West Side neighbourhoods in Vancouver, particularly east Kerrisdale. In particular this project focused on the relationships of power, space and race. From what ethnic background do the owners of these so-called 'Monster' houses and non- 'Monster' houses originate? What are the issues behind the design and landscapes of homes in this area? This project reviewed city by-laws, past and present. At the same time, newspaper coverage of this phenomenon was examined, looking in particular at both the content of articles and the actual titles of these articles. Finally, interviews were conducted to reveal what various people have to say about housing issues in Vancouver.

description: We present an improvement to the cross resonance gate realized with the addition of resonant, target rotary pulses. These pulses, applied directly to the target qubit, are simultaneous to and in phase with the echoed cross resonance pulses. Using specialized Hamiltonian error amplifying tomography, we confirm a reduction of error terms with target rotary -- directly translating to improved two-qubit gate fidelity. Beyond improvement in the control-target subspace, the target rotary reduces entanglement between target and target spectators caused by residual quantum interactions. We further characterize multi-qubit performance improvement enabled by target rotary pulsing using unitarity benchmarking and quantum volume measurements, achieving a new record quantum volume for a superconducting qubit system.

description: In this paper we present a methodology within the multi-criteria paradigm to assist policy decision-making on water management for irrigation. In order to predict farmers' response to policy changes a separate multi-attribute utility function for each homogeneous group, attained applying cluster analysis, is elicited. The results of several empirical applications of this methodology suggest an improvement of the ability to simulate farmers' decision-making process compared to other approaches. Once the utility functions are obtained the policy maker can evaluate the differential impacts on each cluster and the overall impacts in the area of study (i.e. a river basin) by aggregation. On the empirical side, the authors present some studies for different policy instruments including water pricing, water markets, modernization of irrigation systems and a combination of them.

description: Since Mai 2004 Poland is a new EU member country and has, due to the short membership period, little experience in creating rural policy according to the EU regulations. Additionally, there is a centralised planning of rural policies. The aim of the poster is to present how financing of rural policy can be improved by means of scientific programming methods. The study shows how the modelling approach can be used to analyse the optimal budget allocation for the Polish Plan for Development of Rural Areas from a regional perspective to better reach defined objectives.

description: Changes in climatic and policy environments combined with uncertainty related to stochastic environmental fluctuations make design of invasive pest policy challenging. These external changes are often exacerbated by changes in the species characteristics. We discuss facing local change and uncertainty when deciding ex ante on a specific policy strategy. Our empirical case deals with an invasive agricultural pest, Colorado potato beetle, and agricultural production in Finland. Invasions are modelled as temporally random events and stochasticity in key variables is built into the analysis. The viability of two specific policy options is evaluated given uncertainty and local change.

description: During the 14-month period from May 2002 to June 2003, approximately 10 percent of U.S. supermarkets began to offer fresh irradiated ground beef under the stores' own labels. Using a survey of supermarket store managers from this time period, this paper investigates the factors that influenced stores' adoption of irradiated ground beef. Results from the adoption model show that factors associated with competition, merchandising philosophy, and structure in the food retailing industry play a strong role in the decision. Among other results, we find that variables relating to a competitor's adoption status and proximity can increase the likelihood of a store's adoption decision.
A New Method for Calculating Differential Distributions Directly in Mellin Space

Publisher: name: arXiv
Year: 2005
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We present a new method for the calculation of differential distributions directly in Mellin space without recourse to the usual momentum-fraction (or z-) space. The method is completely general and can be applied to any process. It is based on solving the Integration-by-Parts identities when one of the powers of the propagators is an abstract number. The method retains the full dependence on the Mellin variable and can be implemented in any program for solving the IBP identities based on algebraic elimination, like Laporta. General features of the method are: 1) faster reduction, 2) smaller number of master integrals compared to the usual z-space approach and 3) the master integrals satisfy difference instead of differential equations. This approach generalizes previous results related to fully inclusive observables like the recently calculated three-loop space-like anomalous dimensions and coefficient functions in inclusive DIS to more general processes requiring separate treatment of the various physical cuts. Many possible applications of this method exist, the most notable being the direct evaluation of the three-loop time-like splitting functions in QCD.

description: It is well documented that consumers tend to be patriotic in their choices of food. This paper theoretically examines the consequences of such patriotic behavior for agricultural policy, assuming that the policy is decided by the median voter. The analysis is conducted in the framework of a small open economy, with a ricardian production structure. Consumers differ with respect to how much extra they are prepared to pay for a domestically produced agricultural good. The indirect utility functions are used to find the specific values of tariffs and agricultural subsidies that the various households prefer. For the tariff we find that only the group that buys the domestically produced agricultural good will favor a strictly positive tariff. This tariff is higher the more disadvantage the country has in agricultural production. It is more likely that this group is a majority of the population if this country has a high productivity in the agricultural sector and if the patriotic parameter is large.

description: We present evidence to suggest that the study of one dimensional quasi-exactly solvable (QES) models in quantum mechanics should be extended beyond the usual $\sla(2)$ approach. The motivation is twofold: We first show that certain quasi-exactly solvable potentials constructed with the $\sla(2)$ Lie algebraic method allow for a new larger portion of the spectrum to be obtained algebraically. This is done via another algebraization in which the algebraic hamiltonian cannot be expressed as a polynomial in the generators of $\sla(2)$. We then show an example of a new quasi-exactly solvable potential which cannot be obtained within the Lie-algebraic approach.

Best Strategy for Each Team in The Regular Season to Win Champion in The Knockout Tournament

Subjects: subject: Probability (math.PR)

description: In J. Schwenk.(2018) ['What is the Correct Way to Seed a Knockout Tournament?' Retrieved from The American Mathematical Monthly], Schwenk identified a surprising weakness in the standard method of seeding a single elimination (or knockout) tournament. In particular, he showed that for a certain probability model for the outcomes of games it can be the case that the top seeded team would be less likely to win the tournament than the second seeded team. This raises the possibility that in certain situations it might be advantageous for a team to intentionally lose a game in an attempt to get a more optimal (though possibly lower) seed in the tournament. We examine this question in the context of a four team league which consists of a round robin "regular season" followed by a single elimination tournament with seedings determined by the results from the regular season [4]. Using the same probability model as Schwenk we show that there are situations where it is indeed optimal for a team to intentionally lose. Moreover, we show how a team can make the decision as to whether or not it should intentionally lose. We did two detailed analysis. One is for the situation where other teams always try to win every game. The other is for the situation where other teams are smart enough, namely they can also lose some games intentionally if necessary. The analysis involves computations in both probability and (multi-player) game theory.
Optimal Time-Reversal of Multi-phase Equatorial States

description: Even though the time-reversal is unphysical (it corresponds to the complex conjugation of the density matrix), for some restricted set of states it can be achieved unitarily, typically when there is a common de-phasing in a n-level system. However, in the presence of multiple phases (i. e. a different de-phasing for each element of an orthogonal basis occurs) the time reversal is no longer physically possible. In this paper we derive the channel which optimally approaches in fidelity the time-reversal of multi-phase equatorial states in arbitrary (finite) dimension. We show that, in contrast to the customary case of the Universal-NOT on qubits (or the universal conjugation in arbitrary dimension), the optimal phase covariant time-reversal for equatorial states is a nonclassical channel, which cannot be achieved via a measurement/preparation procedure. Unitary realizations of the optimal time-reversal channel are given with minimal ancillary dimension, exploiting the simplex structure of the optimal maps.

Das invasive Potenzial der T. ‚Hybride 207‘ ist gering, aber das interspezifische Konkurrenzvermögen mit spontanen Unkräutern ist größer als bei T. koksaghyz, dessen Populationen innerhalb eines Jahres komplett zusammenbrechen. Künstliche Hybriden der 2×/2× Kreuzungen (T. koksaghyz × T. linearisquameum, oder reziprok oder Rückkreuzungen mit den Eltern) sind diploid, stehen morphologisch zwischen den Eltern und produzieren teilweise Kautschuk: 0,13,7 %. Die Fertilität der F1 hängt von der Verwendung der Eltern als Vater oder Mutter ab. Im Fall von T. linearisquameum als Mutter liegt die Fertilität bei 8597%. Fungiert T. koksaghyz als Mutter liegt die Fertilität bei 1,59%.
description: Uhlemann, I. & Thiele, K. 2024: On artificial F1-hybrids and backcrosses between Taraxacum koksaghyz and species of Taraxacum sect. Taraxacum (T. officinale s. l.) and their invasive potential. Schlechtendalia 41: 1–16. Taraxacum koksaghyz, a rubber producing plant grown in temperate regions, is used together with diploid Taraxacum linearisquameum (sexual T. officinale s. l.) or triploid species of T. sect. Taraxacum (agamospermous (micro-)species of T. officinale s. l.) as parental plants to get artificial rubber producing hybrids. T. koksaghyz × T. oblongatum and T. ‘Hybrid 207’ are extremely rare triploid offspring examples for 2×/3× combinations. The invasive potential of T. ‘Hybrid 207’ seems to be low, but interspecific competition with weeds is stronger than in T. koksaghyz which completely failed to compete against weeds. Artificial hybrids from 2×/2× combinations (T. koksaghyz × T. linearisquameum and reciprocal and backcrosses with parents) are diploid, generally have a morphological intermediate appearance between parents and partially produce rubber (0.13.7%). The fertility of achenes of offsprings depends on the parental function (pollen recipient or pollen donor). In case of T. linearisquameum as pollen recipient, fertility will be high (8597%) and in case of T. koksaghyz as pollen recipient, fertility is low (1.59%).

description: We present the preliminary results on direct photon interferometry measurements in Au+Au collisions at $\sqrt{s_{\rm{NN}}}$ = 62.4 and 200 GeV using the STAR (Solenoidal Tracker at RHIC) detector. Photons are reconstructed via $e^+/e^-$ conversions in STAR Time Projection Chamber(TPC) and energy deposited by photons in STAR Barrel Electromagnetic Calorimeter(BEMC). The two-photon correlations are measured using (1) both photons measured using BEMC; (2) one photon from conversions and the other measured with BEMC. Both the methodologies and the possible constraints in the correlation function measurements are discussed.

description: The XMM-Newton Survey Science Centre Consortium (SSC) develops software in close collaboration with the Science Operations Centre to perform a pipeline analysis of all XMM-Newton observations. In celebration of the 20th launch anniversary, the SSC has compiled the 4th generation of serendipitous source catalogues, 4XMM. The catalogue described here, 4XMM-DR9s, explores sky areas that were observed more than once by XMM-Newton. It was constructed from simultaneous source detection on the overlapping observations, which were bundled in groups ("stacks"). Stacking leads to a higher sensitivity, resulting in newly discovered sources and better constrained source parameters, and unveils long-term brightness variations. As a novel feature, positional rectification was applied beforehand. Observations with all filters and suitable camera settings were included. Exposures with a high background were discarded, which was determined through a statistical analysis of all exposures in each instrument configuration. The X-ray background maps used in source detection were modelled via adaptive smoothing with newly determined parameters. Source fluxes were derived for all contributing observations, irrespective of whether the source would be detectable in an individual observation. From 1,329 stacks with 6,604 contributing observations over repeatedly covered 300 square degrees in the sky, 4XMM-DR9s lists 288,191 sources. 218,283 of them were observed several times. Most stacks are composed of two observations, the largest one comprises 352. The number of observations of a source ranges from 1 to 40. Auxiliary products like X-ray images, long-term light curves, and optical finding charts are published as well. 4XMM-DR9s is considered a prime resource to explore long-term variability of X-ray sources discovered by XMM-Newton. Regular incremental releases including new public observations are planned.

description: Binding energies and density profiles of two-dimensional systems of liquid He-4 with different geometries are studied by means of a zero-range density functional adjusted to reproduce the line tension obtained in a previous diffusion Monte Carlo calculation (lambda_{DMC}=0.121 K/A). It is shown that this density functional provides accurate results for the binding energy of large clusters with a reasonable computational effort.

description: We consider a number of Artificial Chemistry models for economic activity and what consequences they have for the formation of economic inequality. We are particularly interested in what tax measures are effective in dampening economic inequality. By starting from well-known kinetic exchange models, we examine different scenarios for reducing the tendency of economic activity models to form unequal wealth distribution in equilibrium.

description: Cost of production information for major pork exporting countries was collected from producer record systems. The cost of production data for farrow-to-finish operations was reviewed and transformed in comparable categories. The cost comparisons show that like-kind Midwestern U.S. producers have approximate cost differences of $6.00 per cwt marketed. The international farrow-to-finish cost of production per cwt for 1995 is as follows: Western Canada (38.97), large Midwest U.S. (39.03), average Midwest U.S. (43.28), Eastern Canada (46.97), the Netherlands (74.58), and Denmark (77.59). Depending on size and location of operation, cost of production in 1995, ranged from 38.97 to 77.59 cwt marketed.

Intrinsic quantum mechanics behind the Standard Model?

description: We suggest the gauge groups SU(3), SU(2) and U(1) to share a common origin in U(3). We take the Lie group U(3) to serve as an intrinsic configuration space for baryons. A spontaneous symmetry break in the baryonic state selects a U(2) subgroup for the Higgs mechanism. The Higgs field enters the symmetry break to relate the strong and electroweak energy scales by exchange of one quantum of action between the two sectors. This shapes the Higgs potential to fourth order. Recently intrinsic quantum mechanics has given a suggestion for the Cabibbo angle from theory (EPL124-2018) and a prediction for the Higgs couplings to gauge bosons (EPL125-2019). Previously it has given the nucleon mass and the parton distribution functions for u and d quarks in the proton (EPL102-2013). It has given a quite accurate equation for the Higgs mass in closed form (IJMPA30-2015) and an N and Delta spectrum essentially without missing resonances (arXiv:1109.4732). The intrinsic space is to be distinguished from an interior space. The intrinsic space is non-spatial, i.e. no gravity in intrinsic space. The configuration variable is like a generalized spin variable excited from laboratory space by kinematic generators: momentum, spin and Laplace-Runge-Lenz operators. The baryon dynamics resides in a Hamiltonian on U(3) and projects to laboratory space by the momentum form of the wavefunction. The momentum form generates conjugate quark and gluon fields. Local gauge invariance in laboratory space follows from unitarity of the configuration variable and left invariance of the coordinate fields on the intrinsic space. Future work should aim to invoke leptons in the second and third generations and quarks in the third.
