description: This paper is motivated by examples from stochastic reaction network theory. The $Q$-matrix of a stochastic reaction network can be derived from the reaction graph, an edge-labelled directed graph encoding the jump vectors of an associated continuous time Markov chain on the invariant space $\mathbb{N}^d_0$. An open question is how to decompose the space $\mathbb{N}^d_0$ into neutral, trapping, and escaping states, and open and closed communicating classes, and whether this can be done from the reaction graph alone. Such general continuous time Markov chains can be understood as natural generalizations of birth-death processes, incorporating multiple different birth and death mechanisms. We characterize the structure of $\mathbb{N}^d_0$ imposed by a general $Q$-matrix generating continuous time Markov chains with values in $\mathbb{N}^d_0$, in terms of the set of jump vectors and their corresponding transition rate functions. Thus the setting is not limited to stochastic reaction networks. Furthermore, we define structural equivalence of two $Q$-matrices, and provide sufficient conditions for structural equivalence. Examples are abundant in applications. We apply the results to stochastic reaction networks, a Lotka-Volterra model in ecology, the EnvZ-OmpR system in systems biology, and a class of extended branching processes, none of which are birth-death processes.

description: The Gottesman-Kitaev-Preskill encoding of a qubit in a harmonic oscillator is a promising building block towards fault-tolerant quantum computation. Recently, this encoding was experimentally demonstrated for the first time in trapped-ion and superconducting circuit systems. However, these systems lack some of the Gaussian operations which are critical to efficiently manipulate the encoded qubits. In particular, homodyne detection, which is the preferred method for readout of the encoded qubit, is not readily available, heavily limiting the readout fidelity. Here, we present an alternative read-out strategy designed for qubit-coupled systems. Our method can improve the readout fidelity with several orders of magnitude for such systems and, surprisingly, even surpass the fidelity of homodyne detection in the low squeezing regime.

description: Although spending time in a summer home is a popular leisure activity in many developed countries, little is known about the welfare impacts of such recreation in monetary terms. We use data from Finland to provide first estimates of the extent of the recreation benefits obtained from visits to second homes. Special emphasis is placed on how environmental attributes of second homes, such as the presence of algae, the availability of a beach, and electricity, influence the recreation value of visits. The impacts are valued through revealed preferences using the travel cost method. We estimate the recreation value to be about EUR 170 – 205 per trip if a summer home is electrified, if a beach is available and if algae do not prevent aquatic recreation. The aggregate nonmarket benefits of the use of the current summer home stock are considerable – about EUR 500 million per annum. The presence of algae that prevent aquatic recreation decreases the value per trip by 40 percent, and the lack of a beach reduces it by 45 percent; electrification increases the value by 3–5 percent. These impacts should be balanced against the social costs of second homes when designing environmental policies on leisure-time housing.

As a corollary we obtain a proof of the theta block conjecture by Gritsenko, Poor and Yuen for the pure theta blocks obtained as specializations of the functions $\vartheta_R$.

The GHG Balance of Biofuels Taking into Account Land Use Change (Power Point)

description: The contribution of biofuels to the saving of greenhouse gas (GHG) emissions has recently been questioned because of emissions resulting from land use change (LUC) for bioenergy feedstock production. We investigate how the inclusion of the carbon effect of LUC into the carbon accounting framework, as scheduled by the European Commission, impacts on land use choices for an expanding biofuel feedstock production. We first illustrate the change in the carbon balances of various biofuels, using methodology and data from the IPCC Guidelines for National Greenhouse Gas Inventories. It becomes apparent that the conversion of natural land, apart from grassy savannahs, impedes meeting the EU’s 35% minimum emissions reduction target for biofuels. We show that the current accounting method mainly promotes biofuel feedstock production on former cropland, thus increasing the competition between food and fuel production on the currently available cropland area. We further discuss whether it is profitable to use degraded land for commercial bioenergy production as requested by the European Commission to avoid undesirable LUC and conclude that the current regulation provides little incentive to use such land. The exclusive consideration of LUC for bioenergy production minimizes direct LUC at the expense of increasing indirect LUC.

description: Introduction: Total hip arthroplasty (THA) is one of the most frequently performed surgeries worldwide, with high satisfaction rates. However, the orientation of the acetabular component in THA has a direct impact on the risk of dislocation in 2 -3%, the safety zone of 15° anteversion / 45° inclination is described, and these radiographic measurements use the Widmer method. Methods: It is a retrospective study, from the period January 2022 to July 2023, all patients treated with THA at Hospital General Xoco in Mexico City were included. The measurement in degrees of anteversion and inclination was carried out with the Widmer method on postoperative radiographs using the CareStream medical imaging system. Results: 89 patients were studied, 62 women and 27 men, average age of 63±1.7 years, the following data were obtained: the mean inclination averaged 42±1.6°, and anteversion with an angulation of 14.5±1.3°; The diagnosis for which they presented were primary osteoarthrosis in 52.8% of the patients, sequelae of dysplasia in the development of the hip in 13.4% and intracapsular fracture in 33.8%, when discriminating by group inside and outside the Lewinnek safe zone n = 60 and 29 respectively. No episode of dislocation was recorded in our population. Conclusion: In our population, the conventional technique for THA, without the use of navigation systems or support of imaging studies, reported anteversion and inclination figures within the safety parameters.

description: Australian sugar-producing regions have differed in terms of the extent and rate of incorporation of new technology into harvesting systems. The Mackay sugar industry has lagged behind most other sugar-producing regions in this regard. The reasons for this are addressed by invoking an evolutionary economics perspective. The development of harvesting systems, and the role of technology in shaping them, is mapped and interpreted using the concept of path dependency. Key events in the evolution of harvesting systems are identified, which show how the past has shaped the regional development of harvesting systems. From an evolutionary economics perspective, the outcomes observed are the end result of a specific history.

description: We search, in the context of extra-dimension scenarios, for the possible existence of brane fluctuations, called branons. Events with a single photon or a single Z-boson and missing energy and momentum collected with the L3 detector in e^+ e^- collisions at centre-of-mass energies sqrt{s}=189-209$ GeV are analysed. No excess over the Standard Model expectations is found and a lower limit at 95% confidence level of 103 GeV is derived for the mass of branons, for a scenario with small brane tensions. Alternatively, under the assumption of a light branon, brane tensions below 180 GeV are excluded.

description: Imposing military security measures as a consequence of violent conflict may lead to depressing economic effects for all parties involved. One implication is the limited ability to conduct trade, which in turn brings about welfare losses to the economic agents involved and may threat livelihoods and food security. This paper focuses on the consequences of the Israeli-Palestinian conflict, as a prominent example, on bilateral agricultural trade and price dynamics. For this purpose, we consider high-frequency wholesale price data and data on movement restrictions (complete closures) which were imposed by the Israeli Defense Forces in the West Bank between May 2007 and December 2008. In particular, we study the price dynamics of cucumbers and apples, two crops which play an important role for bilateral trade. The spatial and temporal price relationships are assessed using a cointegration framework. Specifically, we use a novel multivariate exogenous regime-switching vector error correction model and employ a recently developed extension of Johansen’s cointegration estimation method. We find the wholesale markets of cucumbers and apples in Hebron and Tel Aviv to be integrated. For both products, the price differentials between both markets quickly adjust to short run deviations from the long-run price equilibria. The regime-dependent model suggests that the movement restrictions effectively cut off both markets from each other temporarily.

description: Highly energetic proton/electron beam fixed target experiments extends an opportunity to probe the sub-GeV dark matter and associated interactions. In this work we have explored the sensitivity of DUNE for sub-GeV leptophobic dark matter i.e. this dark matter barely couples with the leptons. Baryon number gauge theory can predicts the existence of a leptophobic cold dark matter particle candidates. In our work, the dark matter candidate is considered to be scalar whose mass is defined by the symmetry breaking of new baryonic gauge group $U(1)_{B}$. In this scenario a light scalar dark matter couples with the standard model candidates via vector boson mediator $V_{B}$ which belongs to the baryonic gauge group $U(1)_{B}$. This leptophobic dark matter dominantly couples to the quarks. Under this scenario new parameter space for $α_{B}$ is explored by DUNE for leptophobic dark matter candidates. This new parameter space allowed $α_{B}$ to get lower value than the present exiting constraint value of $α_{B}$ i.e. $10^{-6}$.

Subjects: subject: Astrophysics (astro-ph)

description: We report new calculations of the cooling rate of primordial gas by the HD molecule, taking into account its ro-vibrational structure. The HD cooling function is calculated including radiative and collisional transitions for J\le8 rotational levels, and for the vibrational levels v=0,1,2 and 3. The ro-vibrational level population is calculated from the balance equation assuming steady state. The cooling function is evaluated in the ranges of the kinetic temperatures, T_k, from 1e2 to 2e4 K and the number densities, n_H, from 1 to 1e8 cm**-3. We find that the inclusion of collisional ro-vibrational transitions increases significantly the HD cooling efficiency, in particular for high densities and temperatures. For n_H>~1e5 and T_k~1e4 K the cooling function becomes more than an order of magnitude higher than previously reported. We give also the HD cooling rate in the presence of the cosmic microwave radiation field for radiation temperatures of 30, 85 and 275 K (redshifts of 9, 29 and 99). The tabulated cooling functions are available at http://www.cifus.uson.mx/Personal\_Pages/anton/DATA/HD\_cooling/HD\_cool.html. We discuss the relevance to explore the effects of including our results into models and simulations of galaxy formation, especially in the regime when gas cools down from temperatures above ~3000 K.

Attenuating indigenous property rights: land policy after the Wik decision

Year: 1999
Subjects: Land Economics/Use

description: In December 1996, the High Court of Australia handed down its judgment in the Wik case finding, by a 4:3 majority, that pastoral leases did not necessarily extinguish native title. An intense political campaign by both pastoral and indigenous interests, and their political representatives, was aimed, in the case of the former, at legislative extinguishment of native title on pastoral leases and, in the case of the latter, at defending property rights which the High Court found had never been extinguished. In this article it argued that an efficient re-allocation of property rights is unlikely to result from extinguishment, but requires Coasian-type bargains between pastoral and indigenous interests.
The Canadian identity and the right to health care : from waitlists to social citizenship?
Creators: name: Crites, Victoria K.
Publisher: name: University of British Columbia
Year: 2009

description: This thesis examines the recent health care debates and discussions of our "right to health care" amid the claims of a health care "crisis" in Canada, and attempts to determine if, and on what grounds, Canada's system of health care can be considered an entitlement of citizenship. Methodologically, the thesis explores the nexus between a theoretical basis for claiming a right and the policy environment in which that right may or may not be translated into practical policy goals. Here, T.H. Marshall's concept of social citizenship is used as the theoretical framework, in conjunction with the historical evolution of health care policy. Ultimately, the thesis argues that the state is morally obligated to provide social rights of citizenship, such as health care, in order to acknowledge the equality of all citizens. However, it also argues that simply claiming that health care is a right of Canadian citizenship is not sufficient to ensure that the state will provide any particular version of health care. Our publicly-funded universal health care plan, while it is surely tied to the Canadian identity, and has been institutionalized over the last several decades, only entitles Canadians to a thin version of social citizenship. Moreover, the thesis argues that the commitment to social citizenship in Canada is in more of a crisis than is the health care system per se.
An analysis of the Western Australian gold royalty

description: This article analyzes the modified form of ad valorem royalty recently announced by the WA government in relation to gold production, which features a threshold price below which there is no tax liability and compares this royalty with a profit-based royalty. The level at which the threshold price is set plays an important role in determining the performance of the royalty in relation to its impact on production and the expected level and variability of tax revenue. It is argued that the higher this price is set, the stronger the grounds for preferring a profit-based royalty, eve taking into account the reliability of each form for generating tax revenue.

description: We present an examination of the First Ionization Potential (FIP) fractionation scenario invoking the ponderomotive force in the chromosphere, and its implications for the source(s) of slow speed solar winds by using observations from The Advanced Composition Explorer (ACE). Following a recent conjecture that the abundance enhancements of intermediate FIP elements, S, P, and C, in slow solar winds can be explained by the release of plasma fractionated on open fields, though from regions of stronger magnetic field than usually associated with fast solar wind source regions, we identify a period in 2008 containing four solar rotation cycles that show repeated pattern of sulfur abundance enhancement corresponding to a decrease in solar wind speed. We identify the source regions of these slow winds in global magnetic field models and find that they lie at the boundaries between a coronal hole and its adjacent active region, with origins in both closed and open initial field configurations. Based on magnetic field extrapolations, we model the fractionation and compare our results with element abundances measured by ACE to estimate the solar wind contributions from open and closed field, and to highlight potentially useful directions for further work.

We show that the switching rates in this regime are smaller than the rates given by Kramers' formula due to retrapping of Josephson phase. The retrapping process, which is affected by the frequency dependent impedance of the environment of the DC-SQUID, leads to a peaked second moment of the switching distribution as a function of temperature. The temperature where the peaks occur are proportional to the critical current of the DC- SQUID.

Creators: name: Τσαγκουρος Θεοδωρος
Publisher: name: Technical University of Crete
Year: 2022

description: The current thesis concerns electric and electrical waste (e-waste) management via recycling methods. The rapid increase of e-waste volumes poses a significant environmental threat, especially in recent years due to the constant leaps of technology. E-waste recycling stands out as one of the best methods tackling the rising heaps and reclaiming valuable materials. It concerns a wide spectrum of physical, thermal and chemical processes for the separation of materials and the recycling of them in order to be reclaimed. A special part of the overall problem is the management of photovoltaic panel waste. In the global energy transition effort, the use of PV panels is growing rapidly. But as panels have a finite lifespan,their management is just as important when they reach their End of Life (EoL). Similarly, to the general concept of EEE waste, panel recycling processes are physical, thermal or chemical in nature and are intended to recover valuable materials. Addressing the above problems requires a holistic approach and international cooperation. Thus, transnational agreements and regulatory frameworks play an important role in all stages of product life and aim at the
adoption of cyclical models based on recycling.

description: Strategic‐basic research refers to basic research conducted in strategically selected areas expected to be of social benefit. Recent literature on the processes of basic research and its links to applied research has not been widely discussed in relation to agricultural research. This may have important implications for the question of the optimal allocation of research resources. The links are reviewed and combined into a framework for considering the allocation question. A numerical model suggests that only a small number of the model’s parameters substantially affect the optimal level of basic research, and that it is not important to identify the optimal solution precisely, since the benefit function is extremely flat around the optimum.

We address this issue by investigating the large volume limit of the topological susceptibility $χ$ in pure SU(3) gauge theory. We obtain an upper bound for the symmetry breaking order parameter and, as a byproduct, the value χ=(173.4(+/- 0.5)(+/- 1.2)(+1.1 / -0.2) MeV)^4 at β=6 (a approx= 0.1 fermi). The errors are the statistical error from our data, the one derived from the value used for Λ_L and an estimate of the systematic error respectively.

description: Recent high precision data by WMAP and SDSS have provided strong evidence to suggest that the universe is nearly flat. They are also making it possible to probe the topology of the universe. Motivated by these results, we have recently studied the consequences of taking the inflationary limit, i.e. $|Ω_0 - 1| << 1$. We have shown that in this limit a generic detectable spherical or hyperbolic topology is locally indistinguishable from either $R^2 x S^1$ or $R x T^2$, irrespective of its global shape. Here we briefly present these results and further discuss their observational implications.

description: Benefit‐cost analyses of R&D activity in agriculture increasingly form part of the decision‐making process of allocating R&D funds. This article describes how institutional and social influences can affect the rigour and quality of R&D evaluations. The article explores some possible mechanisms for quality control in benefit‐cost analysis so that appraisals are more likely to be accountable and credible assessments rather than false advertising or biased assessments.
On isotropic cylindrically symmetric stellar models

description: We attempt to match the most general cylindrically symmetric vacuum space-time with a Robertson-Walker interior. The matching conditions show that the interior must be dust filled and that the boundary must be comoving. Further, we show that the vacuum region must be polarized. Imposing the condition that there are no trapped cylinders on an initial time slice, we can apply a result of Thorne's and show that trapped cylinders never evolve. This results in a simplified line element which we prove to be incompatible with the dust interior. This result demonstrates the impossibility of the existence of an isotropic cylindrically symmetric star (or even a star which has a cylindrically symmetric portion). We investigate the problem from a different perspective by looking at the expansion scalars of invariant null geodesic congruences and, applying to the cylindrical case, the result that the product of the signs of the expansion scalars must be continuous across the boundary. The result may also be understood in relation to recent results about the impossibility of the static axially symmetric analogue of the Einstein-Straus model.

description: We discuss the interstellar absorption from many atomic and molecular species seen in high-resolution $HST$/STIS UV and high-S/N optical spectra of the moderately reddened B3-5~V star HD~62542. This remarkable sight line exhibits both very steep far-UV extinction and a high fraction of hydrogen in molecular form -- with strong absorption from CH, C$_2$, CN, and CO, but weak absorption from CH$^+$ and most of the commonly observed diffuse interstellar bands. Most of the material resides in a single narrow velocity component -- offering a rare opportunity to probe the primarily molecular core of a single interstellar cloud with little associated diffuse atomic gas. Detailed analyses of the spectra indicate that: (1) the molecular fraction in the main cloud is high [$f$(H$_2$) $>$ 0.8]; (2) the gas is fairly cold ($T_{\rm k}$ = 40--43 K, from the rotational excitation of H$_2$ and C$_2$); (3) the local hydrogen density $n_{\rm H}$ $\sim$ 1500 cm$^{-3}$ (from the C$_2$ excitation, the fine-structure excitation of C$^0$, and simple chemical models); (4) the unusually high excitation temperatures for $^{12}$CO and $^{13}$CO may be largely due to radiative excitation; (5) $N$(C$^+$):$N$(CO):$N$(C) $\sim$ 100:10:1; (6) the depletions of many elements are more severe than those seen in any other sight line, and the detailed pattern of depletions differs from those derived from larger samples of Galactic sight lines; and (7) the various neutral/first ion ratios do not yield consistent estimates for the electron density, even when the effects of grain-assisted recombination and low-temperaure dielectronic recombination are considered.

description: Transport and magnetic properties have been studied in two sets of sol-gel prepared Pr$_{1/2}$Sr$_{1/2}$MnO$_{3}$ nanoparticles having average particle size of 30 nm and 45 nm. Our measurements suggest that the formation of charge ordered state is largely affected due to lowering of particle size, but the ferromagnetic transition temperature ($T_{C}$) remains unaffected.

Educating children with visual impairments : a caseload analysis for British Columbia
Creators: name: De Souza, Julianna
Publisher: name: University of British Columbia
Year: 2009

description: Itinerant teachers of students with visual impairments (TVIs) in British Columbia have long been concerned with the size of their caseloads. TVIs' caseloads are effected by the demands of traveling from student to student, consultations, collaboration meetings, adapting materials as well as other aspects of service management. These can all make providing quality education to children with visual impairments difficult to accomplish within the time given by district and school administrators. In order to ensure quality education, including the Expanded Core Curriculum for visually impaired children, a TV1 must have a manageable caseload. Not having a manageable caseload affects not only the education of children, but also the stress level and attrition of qualified teachers. The stress and attrition of TVIs could lead to further reduction of quality of service for BC's visually impaired population. One way to ensure quality education is being provided is to make sure a TVI has a manageable caseload. This can be accomplished through conducting a caseload analysis. British Columbia does not have a standard method of caseload analysis for its TVIs. Some school districts may be using an established method of caseload analysis, but many are not. Because the incidence of visual impairments for school-aged children is relatively low, teachers may be providing service to children in many districts, and their caseloads should be manageable as well. It is hoped that having one standard method throughout British Columbia will ensure continuity throughout the province as well as provide administrators with a basis for accountability. To establish a standard caseload analysis for BC, a review of already established methods of caseload analysis for TVIs was conducted. Using the same population of students, children attending the Howe Sound School District during the 2002/2003 school year who had been referred for TVI services, each caseload analysis method was utilized. The results and methods of the caseload analysis were compared by professionals in the educational field of visual impairments through a questionnaire and focus group discussion. Their comments and recommendations were compiled and served as a basis for creating a new British Columbia caseload analysis tool (B-CAT).

description: Due to the growing market pressures for innovation, productivity, finality and improvements in the performance and quality of software development projects, an agile methodology emerged. It is focused on continuous improvement of software development and customer satisfaction. However, even with all the positive characteristics that came from this methodology, implementation problems can be found in some types of organizations, such as public ones, for example. This article explores the ontology of knowledge-intensive process (KIPO) through a case study of management of agile methodology in a public company. The result showed that the modeled decision map supported decision making more comprehensively for managers. This enabled technical support to justify decision-making before the Internal Audit and Audit Courts.

description: The study assumed the order measure the level green economies productivity livestock (dairy and beef) in Latin America where emissions of methane (CH4) from enteric fermentation are considered. To make these measurements we used the IPCC Tier 1 method for determining emissions of CH4 and measuring its impact on productivity approach was used for data analysis enclosures (DEA), estimating Malmquist indices. The results show that Ecuador stands with a total factor productivity with a growth rate of 10% during the period 1980-2009, and that this growth was mainly due to technological change represented a 4% rate growth of livestock production where technology involves practices to reduce methane, by the efficiency of labor (farming) of 0.05% assessed deteriorates. In this sense, we find that Costa Rica, Paraguay, Uruguay, Colombia and Guatemala were highlighted with a 7 and 5% in their growth rates to achieve a green economy livestock.

Wound and Rotating Strings in AdS_5 x S^5

description: By using the non-diagonal uniform gauge for the Nambu-Goto string action we derive a gauge-fixed Hamiltonian of a square-root form for the closed string in AdS_5 x S^5 which is wound and rotating in an angular direction in S^5. From the Nambu-Goto string action using a non-diagonal gauge we construct a solution describing a wound string which rotates in the same angular direction as the winding direction. The relation between energy and angular momentum of the string solution is characterized by the winding number and the bending number, and becomes linear in the large angular momentum limit. The small angular momentum limit is compared with the strong coupling limit of the gauge-fixed Hamiltonian. We analyze a wound string solution which is rotating in the different angular direction from the winding direction.

Normes sociales de corpulence et politiques nutritionnelles

description: La construction d'une politique de santé nutritionnelle dans le cadre du Plan national nutrition santé (PNNS) pose la question de l'efficacité relative des outils susceptibles de changer les comportements alimentaires des français, tels que les interventions sur les prix ou la diffusion d'information. Or, l'existence d'interactions sociales entre consommateurs est susceptible de compliquer l'évaluation de ces outils. Supposons, en particulier, qu'une politique publique ait un effet direct sur les comportements de consommation et que ces changements individuels de comportements induisent par agrégation une modification de certaines normes sociales. Alors, si ces normes ont en retour une influence sur les comportements individuels, ceux-ci se verront affectés une seconde fois, de manière indirecte, par la politique publique considérée : l'effet total de cette dernière ne se résume pas à son seul effet direct et immédiat sur les individus. Dans cette optique, nous présentons ici les résultats d'une recherche quantitative visant à identifier l'impact des normes sociales de corpulence sur les représentations individuelles du corps idéal, et l'effet de ces dernières sur les attitudes nutritionnelles. L'objectif était de savoir si les représentations collectives du corps idéal sont un paramètre à prendre en compte dans l'analyse économique des politiques de santé nutritionnelle.

description: We study the vanishing neighbourhood of non-isolated singularities of functions on singular spaces by associating a general linear function. We use the carrousel monodromy in order to show how to get a better control over the attaching of thimbles. For one dimensional singularities, we prove obstructions to integer (co)homology groups and to the eigenspaces of the monodromy via monodromies of nearby sections. Our standpoint allows to find, in certain cases, the structure of the Milnor fibre up to the homotopy type.
