description: Determining the ground state properties of the two-dimensional Hubbard model has remained an outstanding problem. Applying recent advances in constrained path auxiliary-field quantum Monte Carlo techniques and simulating large rectangular periodic lattices, we calculate the long-range spin and charge correlations in the ground state as a function of doping. At intermediate interaction strengths, an incommensurate spin density wave (SDW) state is found, with antiferromagnetic order and essentially homogeneous charge correlation. The wavelength of the collective mode decreases with doping, as does its magnitude. The SDW order vanishes beyond a critical doping. As the interaction is increased, the holes go from a wave-like to a particle-like state, and charge ordering develops which eventually evolves into stripe-like states.

Study of selected Pacific air services : with some implications for a Canadian carrier and Canadian air transport policy
Creators: name: Smallenberg, Gary Allen
Publisher: name: University of British Columbia
Year: 2011

description: The purpose of this study is threefold. Firstly, a working measure of the profitability realized by C.P. Air in their Pacific operations should be derived. This will be gauged through the calculation of profit indicators on each of eight route segments. With the aid of these indicators, some suggestions can be given regarding the presence and degree of cross-subsidization in C.P. Air's overall operation. Secondly, the impact of possible charter development on scheduled services should be ascertained. Uncovering the nature of the Pacific air travel market and the major trends therein will complement the discussion of this evolution. Thirdly, consideration should be given to the implications that arise for Canadian regulatory policy. In particular, reference should be made to the aviation policies set out by the Canadian Transport Commission and to the stated objective of the National Transportation Act of 1967. This will serve to highlight the areas in which regulatory inconsistencies occur and in which questions may be asked concerning the long-run development of Canadian airline companies. Cost and performance data as well as information on the general development of the Pacific air travel market was collected and analyzed. This analysis provided a basis for the study of the Pacific operations of C.P. Air. Through this progressive analysis, profit indicators were derived on a route basis. In order to assess the effect of non-scheduled operators on regular Pacific air services, a gravity-type model was formulated and tested for the years 1962 - 1968. The impact of charters was measured through the inclusion of a "dummy-variable" in the multiple regression framework. The process was further refined to include some factor analysis in order to determine the principal dimensions of demand. Using the results of the statistical analysis, selected aspects of regulatory policy were discussed. This enabled questions to be asked regarding the appropriateness of some current transport policies. It was concluded that C.P. Air was apparently realizing sizeable returns on many Pacific routes. Although it was necessary to qualify this finding, it could not be denied that profits seemed high and C.P. Air would not wish any disturbance to occur. Should charters evolve in the Pacific to a significant magnitude, it was felt a large impact would be made on C.P. Air's scheduled services. Finally, it was concluded that domestic regulatory policy must be improved. The system should encourage efficient operations domestically and reinstate the true, spirit of serving the public interest.
Predictors of grade seven mathematics achievement

description: The study investigated the predictive relationship between Grade Seven mathematics achievement and five intellectual variables: upper‚ÄövÑvÆprimary school mathematics achievement, mathematics aptitude, non‚ÄövÑvÆverbal I.Q., verbal I.Q. and reading comprehension. Subjects for the study were Grade Seven students from a secondary school. Data was provided by student measures on five test instruments which are widely used in primary and secondary schools as measures of academic ability. Basic descriptive statistics, zero‚ÄövÑvÆorder correlations and multiple linear regression techniques allowed for the exploration of several broad questions and issues that emerged from the review of related literature. The study investigated the following issues concerned with prediction of Grade Seven mathematics achievement: 1. that measures of prior mathematics performance are more efficient predictors than global performance measures; 2. that mathematics aptitude is a more efficient predictor than prior mathematics achievement; 3. that non‚ÄövÑvÆverbal I.Q. is a more efficient predictor than verbal I.Q.; 4. that where verbal I.Q. has already been included as a predictor then reading comprehension provides no additional predictive information. Answers to these issues were generally consistent with previous research and were in agreement with theory. The following interpretation was made. The two measures of prior mathematics performance were significantly more efficient predictors than the two measures of global performance. The measures of prior mathematics performance were not significantly different in predictive efficiency, nor were the global performance measures, but mathematics aptitude achieved the highest correlation, accounting for 56% of variance. Verbal I.Q. was a more efficient predictor than reading comprehension. The most efficient prediction was obtained by utilising both measures of prior mathematics performance and both measures of global performance. The four significant predictors together accounted for 66.067% of variance. Using one‚ÄövÑvÆyear cross‚ÄövÑvÆvalidation, a prediction equation was determined. The economic equation used both global performance measures and mathematics aptitude as predictors and achieved a cross‚ÄövÑvÆvalidated correlation coefficient of 0.78.

description: No abstracts are to be cited without prior reference to the author. Viable measures of social well-being and sustainability, including measures of vulnerability and resilience, are needed for coastal fishing communities. Although sustainable development indices have been created and implemented at national and regional levels, few are available at the local or community level. Even fewer address fisheries, especially United States fisheries. Data from more than 2,900 U.S. coastal communities in 19 states were used to create quantitative social vulnerability and fishing dependence indices. The development, utility, and validity of these indices for social impact assessments of fishing communities will be discussed in the context of stock and ecosystem assessments.
Lithofacies and geochemistry of the host sequence to the Currawong massive sulphide deposit, Benambra, Victoria
Creators: name: Ebsworth, Gregory B
Publisher: name: University Of Tasmania
Year: 2023

description: The Currawong massive sulphide deposit is one of two known deposits at Benambra, eastern Victoria. The deposit occurs near the base of the Gibsons Folly Formation which is a deep water, basin centre facies association of the Late Silurian Cowombat Rift (Allen, 1992). Coherent volcanic units of the Gibsons Folly Formation comprise andesite and plagioclase-phyric rhyodacite. These are predominantly shallow sills with margins of sediment-matrix hyaloclastite. The rhyodacite also forms cryptodome-like intrusions which have penecontemporaneously deformed the sequence. These and the sills were emplaced into a relatively unlithified sequence of mudstone (interbedded with thin, fine sandstone turbidites) and andesitic volcaniclastic units prior to the mineralising event. Units of strongly flow-banded and/or brecciated rhyodacite in the footwall sequence may be lavas but textures are equivocal. Quartz-plagioclase-phyric rhyolite (the Currawong Porphyry) is a sill which intruded relatively lithified rocks at the base of the Gibsons Folly Formation. Geochemical evidence indicates that it represents on-going silicic volcanism of the Middle-Upper Silurian Thorkidaan Volcanics. A sequence of andesitic scoriaceous breccia and plagioclase-quartz-bearing altered rocks comprises several depositional units separated by thin mudstone units. These are ambiguous rocks but several features suggest that they are lava-derived mass-flow deposits. They are lithologically and geochemically distinctive and host the mineralisation at Currawong. Ti, Zr, Nb and Y have behaved essentially in an immobile manner during hydrothermal alteration and subsequent metamorphism of the volcanic rocks at Currawong. Volcanic lithologies are best distinguished using the plots Zr/TiO2 vs Nb/Y (after Winchester and Floyd, 1977) and Nb vs Zr. The coherent volcanic units of this sequence form a fairly continuous geochemical magmatic evolution trend but coherent andesite and andesitic volcaniclastic rocks show a broad range of compositions. Some of the andesitic units contain xenocrystic-quartz and volcaniclastic rocks of andesitic composition also contain silicic volcanic clasts. Together these suggest that the andesitic rocks are the result of magmatic differentiation combined with mixing of andesitic and quartz-phyric silicic magmas. The Currawong deposit is interpreted as a subsea-floor replacement style volcanic hosted massive sulphide deposit. Massive pyritic mineralisation is intercalated with, and laterally equivalent to, strongly altered volcanic units which carry variable disseminated or vein mineralisation. Alteration and mineralisation show a strong stratigraphic control related to primary permeability of the host sequence. Quartzxenocrystic, andesitic scoriaceous volcaniclastic rocks were the locus of the strongest mineralisation at Currawong, and possibly at the nearby Wilga deposit. These should be a primary target for future exploration at Benambra.
The combined effect of alcohol and temazepam on information processing
Creators: name: Declerck, Andre
Publisher: name: University Of Tasmania
Year: 2023

description: The present research investigated the separate and interactive effects of high doses of a minor tranquilliser (temazepam) (20 mg) and alcohol (BAC = 0.10%) on human information processing using a dual-task paradigm. For this purpose dual task methodology was combined with P300 amplitude and latency as an index of resource allocation. A dual task paradigm in which subjects were instructed to attend to two tasks concurrently (which had the effect of increasing overall cognitive load) was used to indicate if the affects of alcohol and/or temazepam impaired the contextual updating of neuronal models in the brain and/or reduced specific 'pools of available resources'. Twelve subjects completed four drug treatments in a repeated measures design. The four drug treatments organised in a two by two design, included a placebo condition (alcohol no/temazepam no), an alcohol only condition (alcohol yes/temazepam no), a temazepam only condition (alcohol no/temazepam yes), and a combined condition (alcohol yes/temazepam yes). Event-related potentials were recorded from midline sites Fz, Cz and Pz within a dual task paradigm. The results indicated that at higher doses, widespread neural depression by alcohol overlapped the specific depressant effects of temazepam. The effect of ingesting high doses of alcohol and temazepam was synergistic, that is the combined effects of alcohol and temazepam were greater than their summated individual effects. In terms of information processing, from the perspective of contextual updating the process of updating the pre-existing neuronal model may be restricted, or from the view of resource allocation the actual pool of available resources may have been reduced. The RT data suggested that alcohol and temazepam may have had an additive effect on psychomotor processing. Both alcohol and temazepam significantly increased RT when ingested separately, but there was no interaction between the two drugs. Therefore alcohol and temazepam appeared to affect different aspects of RT processing.

description: The time-periodic scalar delay differential equation $\dot x(t)=γf(t,x(t-1))$ is considered, which leads to a resonant bifurcation of the equilibrium at critical values of the parameter. Using Floquet theory, spectral projection and center manifold reduction, we give conditions for the stability properties of the bifurcating invariant curves and four-periodic orbits. The coefficients of the third order normal form are derived explicitly. We show that the 1:4 resonance has no effect on equations of the form $\dot z(t)=-γr(t)g(x(t-1))$.

description: No abstracts are to be cited without prior reference to the author. Population projections for several groundfish species in the Northwest Atlantic Ocean were evaluated for accuracy, and sources of bias were determined. Forecasts were made ‘retrospectively,’ i.e., assessment data were truncated and forecasts were made during a period with observed catches, observed biological factors (size, weight, maturity), and observed environmental conditions. Both the assessment model and the forecast model were age structured. This framework allowed evaluation of different forecast techniques, and the accuracy of different assumptions about biological factors and environmental interaction could be compared. A secondary consideration was the identification of a feasible time horizon for projections (how many years before forecasts become unreliable) and the implications this has for defining appropriate reference points.

description: We discuss $C^0$-continuous homogeneous quasi-morphisms on the identity component of the group of compactly supported symplectomorphisms of a symplectic manifold. Such quasi-morphisms extend to the $C^0$-closure of this group inside the homeomorphism group. We show that for standard symplectic balls of any dimension, as well as for compact oriented surfaces, other than the sphere, the space of such quasi-morphisms is infinite-dimensional. In the case of surfaces, we give a user-friendly topological characterization of such quasi-morphisms. We also present an application to Hofer's geometry on the group of Hamiltonian diffeomorphisms of the ball.

description: No abstracts are to be cited without prior reference to the author. Mapping using the traditional ecological knowledge (TEK) of the fishers has been scarcely integrated in the management because studies of the reliability of the results are not often provided. We analysed the relationship between a TEK-based fishing ground cartography of the purse seiners of the Ría of Arousa (NW Spain) and the results of a fishery monitoring performed by the same vessels. Fishers tended to fish in the same areas of the TEK cartography, especially the most targeted species with the more detailed cartography
Absolute anticommutativity of the nilpotent symmetries in the Hamiltonian formalism: free Abelian 2-form gauge theory

description: The celebrated Curci-Ferrari (CF) type of restrictions are invoked to obtain the off-shell nilpotent and absolutely anticommuting (anti-) BRST as well as (anti-) co-BRST symmetry transformations in the context of the Lagrangian description of the physical four (3 + 1)-dimensional (4D) free Abelian 2-form gauge theory. We show that the above CF type conditions, which turn out to be the secondary constraints of the theory, remain invariant with respect to the time-evolution of the above 2-form gauge system in the Hamiltonian formulation. This time-evolution invariance (i) physically ensures the linear independence of the BRST versus anti-BRST as well as co-BRST versus anti-co-BRST symmetry transformations, and (ii) provides a logical reason behind the imposition of the above CF type restrictions in the proof of the absolute anticommutativity of the off-shell nilpotent (anti-) BRST as well as (anti-) co-BRST symmetry transformations.

GRB011211: An alternative interpretation of the optical and X-ray spectra in terms of blueshifts
Creators: name: Basu, D.
Publisher: name: arXiv
Year: 2009
Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)
subject: FOS: Physical sciences

description: The redshifts of the gamma ray burst (GRB) GRB 011211 has been determined as 2.14 from several absorption lines seen in the spectrum of its optical afterglow. The spectrum of its X-ray afterglow exhibited several emission lines,and their identification led to a mean redshift 1.862. A supernova model has been proposed based on the redshift of the GRB as 2.141. It is shown here that the redshift interpretation cannot explain the observed spectra, as some serious inconsistencies exist in the process of redshift determinations in spectra of both optical and X-ray afterglows. In view of that, an alternative interpretation of the spectra is presented in terms of blueshifts. Ejection mechanism is proposed as a possible scenario to explain the blueshifted spectrum.

description: No abstracts are to be cited without prior reference to the author. In 2012 NOAA Fisheries began a systematic collection of performance indicators for U.S. fisheries managed under catch share programs. Catch share programs are a fishery management tool that dedicates a secure share of quota allowing individual fishermen, fishing cooperatives, fishing communities, or other entities to harvest a fixed amount of fish. Catch share design varies widely across different programs and regions. These design features are tailored to accommodate the unique characteristics and management objectives for the particular fishery. The fisheries are evaluated using standardized indicators that measure the basic economic performance, regardless of catch share program design. Data collected include landings, revenue and effort data from U.S. catch share programs. Catch share fishery performance is compared to a baseline period prior to implementation of the catch share program. Overall, these programs were successful in having fishermen observe quota limits, improving overall economic benefits and efficiency, and ending the race to fish, thereby reducing pressure on fishermen to fish during unsafe conditions. Catch share programs have been effective in reducing fishing capacity. However, catch share programs have had distributional consequences as reductions in the number of active vessels may have been counterbalanced by reductions in the number of shareholders.
Retail management and the U.B.C. bookstore

description: A research project was undertaken to thoroughly examine the underlying difficulties in the retail operation of the U.B.C. Bookstore and to resolve the question of optimal store location. Merchandising policy was examined and analyzed on the basis of data obtained from interviews with the store's management staff. At the same time three possible store sites were evaluated by collecting data relevant to the operation of a distance decay simulation model which was used to estimate the value of the sites in terms of total sales. The existing site was found to be the most suitable while the problems in retail management were diagnosed as more far-reaching than simply the function of space limitations.

description: No abstracts are to be cited without prior reference to the author. We applied an environmental risk assessment (ERA) framework and linked spatial explicit information on the sensitivity of benthic communities in the German EEZ of the North Sea with the occurrence and magnitude of a governed pressure such as fisheries. We used a spatially resolved Bayesian Belief Network to showcase the steps of risk characterisation, risk analysis and risk evaluation, which are crucial for an informed decision process in marine spatial planning (MSP). The risk analysis produced spatial explicit relative measures of benthic disturbance accounting for bottom trawling frequencies and local frequencies of potential benthic recovery. To account for uncertainty in this step we also assessed different impact weights of the six fishing fleets distinguished and found great differences in spatial disturbance patterns. For the risk evaluation step we simulated a spatial shift of the international fishing effort of two beam trawl fleets, which are affected the most by future offshore wind development. Results showed an increase of local disturbance ratios in 9 % of the study area. In conclusion, MSP processes should embed ERA frameworks which allow for the integration of multiple risk assessments and the quantification of related uncertainties at a common spatial scale.
Hard X-ray observations of Sco X-1 and GX 1+4
Creators: name: Dieters, Stefan W. B.
Publisher: name: University Of Tasmania
Year: 2023

description: Extra-solar X-ray astronomy started in 1962 with the detection of Sco X-1 and the galactic center during a rocket flight designed to find lunar X-rays. Since then, mainly as a result of a series of dedicated satellite missions the number of known (until 1984) X-ray sources had increased to about 1000. This number is comparable to the number stars brighter than 4th magnitude. The X-ray sky at this sensitivity appears as crowded as a moonlit night. The most comprehensive catalogue is that from the HEAO-1 satellite (1977/1978). This catalogue (Wood et al. 1984) lists 842 sources at energies below 20 keV. Unlike optical wavelengths about half the brightest soft to medium energy X-ray sources are associated with extra-galactic objects which are either galaxy groups or active galactic nuclei (AGN eg. Quasars, Seyfert, BL Lac). Fainter AGN may make up the bulk of the diffuse X-ray background. The galactic objects are mainly binary stars containing either a white dwarf or neutron star. The rest are stars with enhanced solar-like activity. The number of known X-ray sources is set to increase to about 100,000 ( much the same as number of stars visible with binoculars) with the completion of the present ROSAT survey. In a twist of history, one of the early ROSAT images actuality showed the moon.

description: No abstracts are to be cited without prior reference to the author. One of the challenges in fishery management is to avoid implementing drastic reductions of fishing activity in yearly basis. Current management usually results in large annual fluctuations in TAC, limiting the ability of the fishing industry to plan for the future. Moreover, plans that recommend drastic capture reductions in the short‐term are not realistic, even if these restrictions suppose higher benefits in the long‐run. This has led to calls for longer term management strategies, especially those that attempt to achieve stability in catches. The aim of the paper is to create an integrated modeling framework, where preferences for less volatile regimes are incorporated into the harvesting strategies. We thus provide a methodology for including environmental, ecological, and societal information in stock and ecosystem assessments. In this framework, the resource manager maximizes the net present value of utility from harvesting and accounts for preferences over fluctuations in harvesting. This is possible by defining preferences over the intertemporal allocation of harvesting, using a constant elasticity of substitution (CES) utility function. The model allows for the evaluation of candidate management strategies in terms of tradeoffs: between the percentages of variation of catch and the variation in biodiversity

description: Different choices exist for the renormalisation group resummation in the determination of $α_s$ from hadronic $τ$ decays: namely fixed-order (FOPT) and contour-improved perturbation theory (CIPT). The two approaches lead to systematic differences in the resulting $α_s$. On the basis of a model for higher-order terms in the perturbative series, which incorporates well-known structure from renormalons, it is found that while CIPT is unable to account for the fully resummed series, FOPT smoothly approaches the Borel sum. Employing the model to determine $α_s$ yields $α_s(M_τ)=0.316 \pm 0.006$, which after evolution leads to $α_s(M_Z) = 0.1180 \pm 0.0008$.

Comments. The P. testacea -group proposed by Zwick (1982a) includes six formally recognized species and two recognized by informal designation (Table 1). Zwick (1982a) noted the male “…Ceylonese members of this group, the testacea -group sensu stricto, are the most difficult species in the genus…” to distinguish. He further indicated that specimens of females with eggs are essential for species recognition in the group. All specimens of P. testacea and P. wedda (see below) in this sample were consistent in lacking a sternal brush on segment 8, and in having one on segment 7 (Fig. 21), but the number of Rs veins, the details of the median patch of sensilla basiconica on tergum 9 and the aedeagal features varied, at least subtly, as detailed by Zwick (1982a). It seemed probable, given the number of male specimens we examined from sites where female specimens of P. wedda dominate, that Zwick’s (1982a) indication, regarding the presence of sternal brushes on male abdominal segment 8 for Sri Lankan members of the testacea- group, might be in error. This has been confirmed now for small samples of P. limosa, P. srilanka, P. testacea and P. wedda (P. Zwick, pers. com., and our observations). Unfortunately, we have not had an opportunity to check this character for specimens of P. ceylonica, consequently we have not included this species in our revised key (below) to Sri Lankan and Indian Phanoperla males.

description: The 1/N_c expansion of QCD with N_c=3 has been successful in explaining a wide variety of QCD phenomenology. Here I focus on the contracted spin-flavor symmetry of baryons in the large-N_c limit and deviations from spin-flavor symmetry due to corrections suppressed by powers of 1/N_c. Baryon masses provide an important example of the 1/N_c expansion, and successful predictions of masses of heavy-quark baryons continue to be tested by experiment. The ground state charmed baryon masses have all been measured, and five of the eight ground state bottom baryon masses have been found. Results of the 1/N_c expansion can aid in the discovery of the remaining bottom baryons. The brand new measurement of the Ω_b^- mass by the CDF collaboration conflicts with the original D0 discovery value and is in excellent agreement with the prediction of the 1/N_c expansion.

description: Amplitude representations of a binary phase field crystal model are developed for a two dimensional triangular lattice and three dimensional BCC and FCC crystal structures. The relationship between these amplitude equations and the standard phase field models for binary alloy solidification with elasticity are derived, providing an explicit connection between phase field crystal and phase field models. Sample simulations of solute migration at grain boundaries, eutectic solidification and quantum dot formation on nano-membranes are also presented.

description: No abstracts are to be cited without prior reference to the author. There are 18 species of sharks and rays in the North Sea populating all ecological niches from coastal to offshore, pelagic and demersal. These species are characterised by their late maturity and low fecundity, making them extra sensitive to enhanced mortality by fishing and loss of coastal and offshore habitats for nursery and feeding. Many of the species are included in international policy and conservation guidelines as threatened or some, for example the common skate, are locally extinct in the North Sea. For the implementation of the Marine Strategy Framework Directive the Dutch government requires advice on measures for sharks and rays. An advisory management plan for these species has been written over a period of 18 months during a participative process in which scientists, NGOs, fishermen, fisheries representatives and government officials were invited to share their expertise to help formulate management objectives and measures. The Dutch Agricultural Institute (LEI) carried out a cost-effectiveness study for the measures. This presentation examines the interactive process used to formulate management objectives and measures for sharks and rays in the Dutch part of the North Sea and explores the different styles of participation of stakeholders in this process.
Data management for hospital administration

description: In hospitals, as in business, the literature bears evidence of successful implementation of specialized computer systems. Unfortunately, all attempts at designing large-scale totally integrated hospital information systems have so far been unsuccessful. It seems apparent that the missing link between the dedicated systems and the "total" systems is the non-utilization of the systems approach. To demonstrate the importance and the practicality of this approach, it is used to outline and evaluate the criteria applicable in choosing a data management system for hospital administration.
Death of a cluster: the destruction of M67 as seen by the SDSS

description: We probe the spatial and dynamical structure of the old open cluster M67 using photometric data from the Sloan Digital Sky Survey's sixth data release. Making use of an optimal contrast, or matched filter, algorithm, we map the distribution of high probability members of M67. We find an extended and elongated halo of likely members to a radius of nearly 60'. Our measured core radius of Rcore = 8.'24+/-0.'60 is somewhat larger than that of previous estimates. We attribute the larger core radius measurement to the SDSS probing lower mass main sequence stars than has been done before for similar studies of M67, and the exclusion of post main sequence M67 members in the SDSS sample. We estimate the number of M67 members in our SDSS sample to be 1385+/-67 stars. A lower limit on the binary fraction in M67 is measured to be 45%. A higher fraction of binary stars is measured in the core as compared to the halo, and the luminosity function of the core is found to be more depleted of low-mass stars. Thus the halo is consistent with mass segregation within the cluster. The galactic orbit of M67 is calculated from recent proper motion and radial velocity determinations. The elongated halo is roughly aligned to the proper motion of the cluster. This appears to be a result of mass segregation due to the galactic tidal field. Our algorithm is run on 2MASS photometry to directly compare to previous studies of M67. Decreasing core radii are found for stars with greater masses. We test the accuracy of our algorithm using 1000 artificial cluster Monte Carlo simulations. It is found that the matched filter technique is suitable for recovering low-density spatial structures, as well as measuring the binary fraction of the cluster.

Simulated induction & its application to botanical key generation
Creators: name: Faulkner, E G
Publisher: name: University Of Tasmania
Year: 2023

description: The dissatisfaction expressed by taxonomists with the results obtained from automatic key-generation methodologies employing deductive logic led to an examination of interactive key generation methodologies employing inductive logic. Philosophical and psychological aspects of induction were examined to ensure that the resulting methodology would be philosophically and psychologically acceptable, and a case was made that such methods would in fact be more widely understood in the community than deductively-based methodologies. The effects of the discussion on the debate about the existence of artificial intelligence and the problems of obtaining rules for expert systems were noted, and a computerised methodology implemented. The results of applying this methodology to Tasmanian data obtained from measurements of specimens of the Acaena complex and Danthonia genus were compared with several competing methodologies, namely clustering, neural networks, discriminant analysis, a paper-based key produced by a domain expert and entropy-based methodologies. The results obtained were either similar or superior to the competing methodologies; perhaps because the methodology implemented combined the strengths of each of the participants, i.e. the tireless calculating ability of the computer with the background knowledge and common sense of the domain expert. With some types of data, the methodology was also less computationally intensive than some competing methodologies.

description: No abstracts are to be cited without prior reference to the author. The Large Fish Indicator (LFI) describes changes in the proportion of large fish at community level and gives an indication about its state. In the North Sea (>40cm total length), although proposed as an indicator of Good Environmental Status, the LFI may vary between different regions. Using data from the International Bottom Trawl Survey (IBTS) and Beam Trawl Survey (BTS), we investigated the LFI response to recent changes in fishing mortality rates. To examine changes in LFI trends, we calculated the indicator for different areas of the North Sea. The indicator responded to changes in fishing mortality but mainly based on BTS data. Moreover, when calculated with IBTS data, the indicator was highly influenced by single species contribution such as cod, underpinning that the LFI might be more sensitive to other pressures than fishing. A suite of indicators covering different data, dimensions and processes would elucidate trends and rapid changes of the LFI. The BTS survey can provide a reliable sound basis of information for calculating the LFI in the southern North Sea waters.

description: The entanglement properties of a multiparty pure state are invariant under local unitary transformations. The stabilizer dimension of a multiparty pure state characterizes how many types of such local unitary transformations existing for the state. We find that the stabilizer dimension of an $n$-qubit ($n\ge 2$) graph state is associated with three specific configurations in its graph. We further show that the stabilizer dimension of an $n$-qubit ($n\ge 3$) graph state is equal to the degree of irreducible two-qubit correlations in the state.

description: We study observational implications of the stochastic gravitational wave background and a non-Gaussian feature of scalar perturbations on the curvaton mechanism of the generation of density/curvature fluctuations, and show that they can determine the properties of the curvaton in a complementary manner to each other. Therefore even if Planck could not detect any non-Gaussianity, future space-based laser interferometers such as DECIGO or BBO could practically exhaust its parameter space.
