description: The crayfish plague pathogen (Aphanomyces astaci) is one of the most important threats to indigenous European crayfish. Although it belongs among the most studied pathogens of invertebrates, only a few recent studies are available on the epidemiology of crayfish plague and its long-term effects on crayfish populations. We provide detailed data on 11 populations of European crayfish (Astacus astacus, A. leptodactylus, Austropotamobius torrentium) hit by crayfish plague in the Czech Republic between 1998 and 2011. We repeatedly surveyed the affected localities in the years following the disease outbreaks to investigate potential recovery of crayfish populations and to search for the likely sources of infection. Although the mortalities severely decimated all studied populations, European crayfish could be found in the watercourse catchments after the disease outbreaks in all but two cases. In five cases, migration barriers apparently supported crayfish survival; in two cases, the disease stopped spreading even without the presence of any barrier. Indigenous crayfish were recorded directly in the affected parts of five studied streams after some time but in most cases populations have not yet reached the original densities. Their recovery seems influenced by the population size in unaffected refuges as well as time since the outbreak. Sources of infection and transmission pathways of A. astaci apparently vary in the Czech Republic. Aphanomyces astaci of three genotype groups originating in different crayfish plague pathogen carriers were involved in the outbreaks. Direct transmission of A. astaci from invasive American crayfish present in the same stream is likely in three cases; however, these host crayfish were not recorded at the remaining localities, and long-range dispersal or other pathogen sources may be assumed. We hypothesize that chronic A. astaci infections leading to disease outbreaks under specific conditions may occur in some populations of indigenous crayfish in the Czech Republic.

description: Using a representative set of 10 of the worst invasive species in Europe, this study investigates the relative importance of climatic, habitat and socio-economic factors in driving the occurrence of invasive species. According to the regression models performed, these factors can be interpreted as multi-scale filters that determine the occurrence of invasive species, with human degradation potentially affecting the performance of the other two environmental filters. Amongst climate factors, minimum temperature of the coldest month was one of the most important drivers of the occurrence of Europe’s worst freshwater and terrestrial invaders like the red swamp crayfish (Procambarus clarkii), Bermuda buttercup (Oxalis pes-caprae) and Sika deer (Cervus nippon). Water chemistry (alkalinity, pH, nitrate) determines the availability of habitat and resources for species at regional to local levels and was relevant to explain the occurrence of aquatic and semi-aquatic invaders such as the brook trout (Salvalinus fontinallis) and Canada goose (Branta canadensis). Likewise, nitrate and cholorophyll-a concentration were important determinants of marine invaders like the bay barnacle (Balanus improvisus) and green sea fingers (Codium fragile). Most relevant socio-economic predictors included the density of roads, country gross domestic product (GDP), distance to ports and the degree of human influence on ecosystems. These variables were particularly relevant to explain the occurrence of the zebra mussel (Dreissena polymorpha) and coypu (Myocastor coypu), species usually associated to disturbed environments. The Japanese kelp (Undaria pinnatifida) was generally distributed much closer to ports than the other two marine organisms, although insufficient information on human impacts prevented a correct assessment of the three marine species. In conclusion, this study shows how socio-economic development is associated with the presence of the top 10 worst European invasive species at a continental scale, and relates this fact to the provision and transport of propagules and the degradation of natural habitats that favour the establishment of invasive species.
Quantum limits to center-of-mass measurements

Year: 2024

description: We discuss the issue of measuring the mean position (center of mass) of a group of bosonic or fermionic quantum particles, including particle number fluctuations. We introduce a standard quantum limit for these measurements at ultralow temperatures, and discuss this limit in the context of both photons and ultracold atoms. In the case of non-interacting harmonically trapped fermions, we present evidence that the Pauli exclusion principle has a strongly beneficial effect, giving rise to a 1 N scaling in the position standard deviation-as opposed to a 1 N scaling for bosons. The difference between the actual mean-position fluctuation and this limit is evidence for quantum wave-packet spreading in the center of mass. This macroscopic quantum effect cannot be readily observed for noninteracting particles, due to classical pulse broadening. For this reason, we also study the evolution of photonic and matter-wave solitons, where classical dispersion is suppressed. In the photonic case, we show that the intrinsic quantum diffusion of the mean position can contribute significantly to uncertainties in soliton pulse arrival times. We also discuss ways in which the relatively long lifetimes of attractive bosons in matter-wave solitons may be used to demonstrate quantum interference between massive objects composed of thousands of particles.

Correlations in a BEC collision: First-principles quantum dynamics with 150000 atoms
Creators: name: Deuar, P.

Publisher: name: Swinburne
Year: 2024

description: The quantum dynamics of colliding Bose-Einstein condensates with 150000 atoms are simulated directly from the Hamiltonian using the stochastic positive-P method. Two-body correlations between the scattered atoms and their velocity distribution are found for experimentally accessible parameters. Hanbury Brown-Twiss or thermal-like correlations are seen for copropagating atoms, while number correlations for counterpropagating atoms are even stronger than thermal correlations at short times. The coherent phase grains grow in size as the collision progresses with the onset of growth coinciding with the beginning of stimulated scattering. The method is versatile and usable for a range of cold atom systems.

Visualization of vortex bound states in polarized fermi gases at unitarity

Publisher: name: Swinburne
Year: 2024

description: We theoretically analyze a single vortex in a spin polarized 3D trapped atomic Fermi gas near a broad Feshbach resonance. Above a critical polarization the Andreev-like bound states inside the core become occupied by the majority spin component. As a result, the local density difference at the core center suddenly rises at low temperatures. This provides a way to visualize the lowest bound state using phase-contrast imaging. As the polarization increases, the core expands gradually and the energy of the lowest bound state decreases.

description: Invasive alien species are one of the major agents of human-accelerated global change: they threaten biodiversity, alter ecosystem structure, functions and services, inflict large economic costs and cause serious problems to human health. The effects on human health are indeed a major problem and also cause substantial costs but, surprisingly, very few studies have analyzed this topic. The paper describes and analyses the hazards to human health associated with species introductions, and discusses major correlates and possible responses. Four categories were identified: invasive species (1) causing diseases or infections; (2) exposing humans to wounds from bites/stings, biotoxins, allergens or toxicants; (3) faciliting diseases, injuries or death; and (4) inflicting other negative effects on human livelihood. Invasive species affect human health via several ways, i.e. as alien pathogens and invaders that bring/facilitate parasites or produce toxins. Others cause denutrition/malnutrition or exert displaced or deferred impacts. Their negative impacts are expected to intensify in the near future due to the increased opportunities of invasions associated with climate change, the augmented pathways of introductions and the synergic effects of climate change. It is imperative to improve our understanding of the pathways of arrival of invasive species affecting human health, their biological patterns and the mechanisms of impact, because all this information is essential to develop more effective and stringent policies for preventing and mitigating the negative effects that these species cause.

Mean-field thermodynamics of a spin-polarized spherically trapped Fermi gas at unitarity
Creators: name: Liu, Xiaji

Publisher: name: Swinburne
Year: 2024

description: We calculate the mean-field thermodynamics of a spherically trapped Fermi gas with unequal spin populations in the unitarity limit, comparing results from the Bogoliubov-de Gennes equations and the local density approximation. We follow the usual mean-field decoupling in deriving the Bogoliubov-de Gennes equations and set up an efficient and accurate method for solving these equations. In the local density approximation we consider locally homogeneous solutions, with a slowly varying order parameter. With a large particle number these two approximation schemes give rise to essentially the same results for various thermodynamic quantities, including the density profiles. This excellent agreement strongly indicates that the small oscillation of order parameters near the edge of trap, sometimes interpreted as spatially inhomogeneous Fulde-Ferrell-Larkin-Ovchinnikov states in previous studies of Bogoliubov-de Gennes equations, is a finite-size effect. We find that a bimodal structure emerges in the density profile of the minority-spin state at finite temperature, as observed in experiments. The superfluid transition temperature as a function of the population imbalance is determined and is shown to be consistent with recent experimental measurements. The temperature dependence of the equation of state is discussed.

description: Non-directional re-flooding of the wetlands in southern Iraq, which were extensively drained during the 1990s, started in 2003. The change in species composition and abundance of rotifer and cladoceran communities together with their abiotic environment were studied for 15 months in the re-flooded wetlands. The re-flooded wetlands were characterized by higher salinity than typical freshwater inland marshes, and some rotifer and cladoceran species were characteristic of the saline, post-re-flooding environment. The changes in species composition and abundance of rotifers were mostly seasonal, demonstrated by the cyclic changes in principal component analysis and their positive relationships to water temperature. Al-Huwaiza Marsh is distinguished from the other two marshes (Central and Al-Hammar Marshes) and is characterized by relatively lower and stable salinity, close to neutral pH, near or above saturation DO, and lower SO4−2. These characteristics might explain the differences in recovery processes of zooplankton communities among the three marshes. The Jaccard's similarity index for Cladocera revealed similarity between the two stations of each marsh (in terms of maximum densities recorded); however, this was not mirrored by Rotifera. Al-Huwaiza Marsh stations were very similar to each other, whereas the Al-Hammar and Central Marshes had one station of each very similar to the other station of the other marsh. Cladocera and Rotifera are predominantly freshwater species; Rotifera is more sensitive to water quality changes, particularly salinity, than the Cladocera. The observed seasonal cycles of zooplankton communities might suggest that the system was stabilizing during the study period. However, water supply shortages since 2008 continue to threaten the wetlands.

description: In this work, we computed IDF curves for the climatically and topographically diverse Chilean territory (17-56ºS) using both stationary and non-stationary approaches based on three state-of-the-art gridded datasets:

i) the Integrated Multi-Satellite Retrievals for GPM (IMERGv06B),

ii) the fifth generation ECMWF ERA5 reanalysis, and

iii) ERA5-Land, the high-resolution reanalysis from ECMWF.

The three gridded datasets were used to compute the annual maximum intensities for 12 durations (1, 2, 4, 6, 8, 10, 12, 18, 24, 48, and 72 h) and six return periods (T=2, 5, 10, 25, 50, and 100 years), for the 2001-2021 period , using a common spatial resolution of 0.10° and hourly temporal resolution. Data from 161 quality-checked hourly rain gauges are used to calculate IDF curves that serve as a benchmark for the curves derived from the gridded datasets.

First, we calculated bias correction factors for the annual maximum intensities (Imax) for each duration, based on the comparison of the gridded value with the point one. Second, the previous correction factors were applied to the annual maximum intensities derived from each gridded dataset, using splines over the entire spatial domain. Third, the bias-corrected annual maximum intensities were calculated for each duration and return period using the Gumbel probability distribution, assuming stationary conditions. Then, the same annual maximum intensities were calculated for each duration and return period using a non-stationary Gumbel probability distribution with a varying mean. Fifth, we used the non-parametric Mann-Kendall test to assess the existence of trends in annual maximum intensities. Finally, 41 (1981-2021) and 21 (2001-2021) years of hourly precipitation data from ERA5 and ERA5-Land were used to test the effects of data length on the resulting stationary and non-stationary IDF curves.

Our results reveal how the bias of annual maximum intensities changes in space, with generally smaller biases for longer durations. In addition, minor differences were found between the maximum annual intensities calculated using the stationary and non-stationary approaches for 2001-2021. Unexpectedly, we found some significant decreasing trends (p-value < 0.05) in Central-Southern Chile (32-43ºS) for the annual maximum intensities derived from ERA5 and ERA5-Land, while these trends were more localised and divergent (increasing and decreasing) for IMERG. Finally, there were only minor differences between the annual maximum intensities derived from ERA5 and ERA5-Land when using 21 years compared to 41 years of hourly records, for both the stationary and non-stationary approaches.

Phase diagram of a strongly interacting polarized fermi gas in one dimension

Publisher: name: Swinburne
Year: 2024

description: Based on the integrable Gaudin model and local density approximation, we discuss the ground state of a one-dimensional trapped Fermi gas with imbalanced spin population, for an arbitrary attractive interaction. A phase separation state, with a polarized superfluid core immersed in an unpolarized superfluid shell, emerges below a critical spin polarization. Above it, coexistence of polarized superfluid matter and a fully polarized normal gas is favored. These two exotic states could be realized experimentally in highly elongated atomic traps, and diagnosed by measuring the lowest density compressional mode. We identify the polarized superfluid as having an Fulde-Ferrell-Larkin-Ovchinnikov structure, and predict the resulting mode frequency as a function of the spin polarization.

Publisher: name: Swinburne
Year: 2024

description: The stochastic-gauge representation is a method of mapping the equation of motion for the quantum mechanical density operator onto a set of equivalent stochastic differential equations. One of the stochastic variables is termed the 'weight', and its magnitude is related to the importance of the stochastic trajectory. We investigate the use of Monte Carlo algorithms to improve the sampling of the weighted trajectories and thus reduce sampling error in a simulation of quantum dynamics. The method can be applied to calculations in real time, as well as imaginary time for which Monte Carlo algorithms are more-commonly used. The Monte-Carlo algorithms are applicable when the weight is guaranteed to be real, and we demonstrate how to ensure this is the case. Examples are given for the anharmonic oscillator, where large improvements over stochastic sampling are observed.

description: In 1986 David Lynch brought the suburbs into focus. Before Lynch they had remained slightly bland and indistinct, white picket fences and lush green lawns in the background of Doris Day comedies, Douglas Sirk films and television sitcoms. But in the opening shots of Blue Velvet (1986) Lynch announced that he was going to do something quite different. He skipped through the stock suburban footage of vibrant colours---the red roses, the blue skies, the happy, smiling faces of the children---preferring instead, to track through the grass. There, through a series of grotesque close-ups of seething, warring insects, Lynch revealed the anomalies and ambiguities beneath the bright and shiny surface of suburbia.
Uncertainty quantification of unconventional reservoirs using assisted history matching methods

Reservoir characterization

description: A hallmark of unconventional reservoirs is characterization uncertainty. Assisted History Matching (AHM) methods provide attractive means for uncertainty quantification (UQ), because they yield an ensemble of qualifying models instead of a single candidate. Here we integrate embedded discrete fracture model (EDFM), one of fractured-reservoirs modeling techniques, with a commercial AHM and optimization tool. We develop a new parameterization scheme that allows for altering individual properties of multiple wells or fracture groups. The reservoir is divided into three types of regions: formation matrix; EDFM fracture groups; and stimulated rock volume (SRV) around fracture groups. The method is developed in a sleek, stand-alone form and is composed of four main steps: (1) reading parameters exported by tool; (2) generating an EDFM instance; (3) running the instance on a simulator; and (4) calculating a pre-defined objective function. We present two applications. First, we test the method on a hypothetical case with synthetic production data from two wells. Using 20 history-matching parameters, we compare the performance of five AHM algorithms. Two of which are based on Bayesian approach, two are stochastic particle-swarm optimization (PSO), and one is commercial DECE algorithm. Performance is measured with metrics, such as solutions sample size, total simulation runs, marginal parameter posterior distributions, and distributions of estimated ultimate recovery (EUR). In the second application, we assess the effect of natural fractures on UQ of a single horizontal well in the middle Bakken. This is achieved by comparing four AHM scenarios with increasingly varying natural-fracture intensity. Results of the first study show that, based on pre-set acceptance criteria, DECE fails to generate any satisfying solutions. Bayesian methods are noticeably superior to PSO, although PSO is capable to generate large number of solutions. PSO tends to be focused on narrow regions of the posteriors and seems to significantly underestimate uncertainty. Bayesian Algorithm I, a method with a proxy-based acceptance/rejection sampler, ranks first in efficiency but evidently underperforms in accuracy. Results from the second study reveal that, even though varying intensity of natural fractures cam significantly alter other model parameters, that appears not to have influence on UQ (or long-term production)

description: We report new experiments that test quantum dynamical predictions of polarization squeezing for ultrashort photonic pulses in a birefringent fibre, including all relevant dissipative effects. This exponentially complex many-body problem is solved by means of a stochastic phase-space method. The squeezing is calculated and compared to experimental data, resulting in excellent quantitative agreement. From the simulations, we identify the physical limits to quantum noise reduction in optical fibers. The research represents a significant experimental test of first-principles time-domain quantum dynamics in a one-dimensional interacting Bose gas coupled to dissipative reservoirs.

description: We present a theory for a superfluid Fermi gas near the BCS-BEC crossover, including pairing fluctuation contributions to the free energy similar to that considered by Nozieres and Schmitt-Rink for the normal phase. In the strong coupling limit, our theory is able to recover the Bogoliubov theory of a weakly interacting Bose gas with a molecular scattering length very close to the known exact result. We compare our results with recent Quantum Monte Carlo simulations both for the ground state and at finite temperature. Excellent agreement is found for all interaction strengths where simulation results are available.

Gaussian phase-space representations for fermions
Creators: name: Corney, J. F.

Publisher: name: Swinburne
Year: 2024

description: We introduce a positive phase-space representation for fermions, using the most general possible multimode Gaussian operator basis. The representation generalizes previous bosonic quantum phase-space methods to Fermi systems. We derive equivalences between quantum and stochastic moments, as well as operator correspondences that map quantum operator evolution onto stochastic processes in phase space. The representation thus enables first-principles quantum dynamical or equilibrium calculations in many-body Fermi systems. Potential applications are to strongly interacting and correlated Fermi gases, including coherent behavior in open systems and nanostructures described by master equations. Examples of an ideal gas and the Hubbard model are given, as well as a generic open system, in order to illustrate these ideas.

description: This paper presents our research on awareness support in Instant Messaging (IM). The paper starts with a brief overview of an empirical study of IM, using an online survey and face-to-face interviews to identify user needs for awareness support. The study identified a need for supporting four aspects of awareness—awareness of multiple concurrent conversations, conversational awareness, presence awareness of a group conversation, and visibility of moment-to-moment listeners and viewers. Based on the empirical study and existing research on awareness, we have developed the F@ (read as “fat”) framework of awareness. F@ comprises of an abstract level and a concrete level. The former level includes an in-depth description of various awareness aspects in IM, whilst the latter level utilises temporal logic to formalise fundamental time-related awareness aspects. F@ helps developers gain a better understanding of awareness and thereby design usable mechanisms to support awareness. Applying F@, we have designed several mechanisms to support various aspect of awareness in IM.

description: We present theoretical predictions for the equation of state of a harmonically trapped Fermi gas in the unitary limit. Our calculations compare Monte Carlo results with the equation of state of a uniform gas using three distinct perturbation schemes. We show that in experiments the temperature can be usefully calibrated by making use of the entropy, which is invariant during an adiabatic conversion into the weakly interacting limit of molecular BEC. We predict the entropy dependence of the equation of state.

description: Particle number, size, and composition information is important for constraining aerosol effects on air quality, climate, and health. The composition of particles, especially from vehicular sources, may contain insoluble black carbon (BC) materials that modify particle nucleating properties. In this study, we develop a method to provide quantitative and real-time information on the water-insoluble components found in near-road aerosol sources. A water-based condensation particle counter (W-CPC) and a butanol-based CPC (B-CPC) were used to measure the particle number concentration. Both instruments were coupled with a scanning mobility particle sizer (SMPS) to record the particle number and size data. Real time water-insoluble particle mass was estimated from the difference in particle number concentration between the two CPCs; theoretical water-insoluble mass was calculated from the ideal hygro- scopicity single parameter κ-values. This online method was calibrated with test compounds and then applied to data collected from a field study. Ambient aerosol was sampled from a monitoring station located 15 m from the I-710 freeway in Long Beach, California. The results show that near-roadway emissions contain water-insoluble (BC and non-BC) components. Particle number and BC concentrations increase after changes in wind direction near the freeway on both weekday and weekend measurements. Particles were less hygroscopic (κ ∼ 0.2) before changes in wind direction from downwind to upwind of the freeway (κ > 0.6). Rapid changes in water-solubility can be captured with this technique. By assuming a two-component mixture, the water-insoluble mass fractions were inferred. BC shows a positive correlation with the water-insoluble mass however its presence may not account for the entire water-insoluble mass from the near-roadway source.Copyright 2014 American Association for Aerosol Research

description: ABSTRACTConcentrations of 16 priority polycyclic aromatic hydrocarbons (PAHs) were determined in 40 brands of biscuits in the Nigerian market. The analyses were performed by gas chromatography-flame ionisation detection (GC-FID) after Soxhlet extraction of the sample with hexane/dichloromethane and clean-up of the extract. The concentrations of Σ16 PAHs in these biscuit samples were in the range of 35.7–645.3 μg kg−1, 75.9–490.7 μg kg−1, 91.5–537 μg kg−1, 18.4–522.2 μg kg−1, 123.5–393.8 μg kg−1, 167.2–880 μg kg−1, 136.5–316 μg kg−1, and 135.5–241.6 μg kg−1 for shortcake, digestives, cookies, shortbread, wafers, crackers, Pringles, and cabin, respectively. The concentrations of Σ8 carcinogenic PAHs in the samples ranged from not detected (nd)–323.3 μg kg−1, 15.7–138 μg kg−1, 9.7–312.9 μg kg−1, nd–331.7 μg kg−1, nd–220.9 μg kg−1, nd–53.3 μg kg−1, 18.4–56.6 μg kg−1, and 6.6–170.8 μg kg−1 for shortcake, digestives, cookies, shortbread, wafers, crackers, Pringles, and cabin, respectively. The margin of exposure (MOE), based on PAH8 as an indicator for the occurrence and effects of PAHs in food, was less than 10,000, the serious health effects value, in 30% and 8% of the brands for the child and adult scenarios, respectively.

description: Le terme « développement durable » apparaît dans la littérature au début des années 1980. Toutefois, c’est en 1987, dans le rapport de la Commission mondiale pour le développement et l'environnement de l'Organisation des Nations Unies de Gro Harlem Brundtland que ce concept va sortir de l’ombre et être présenté au grand public. L’intérêt porté à cette problématique a fait émerger la notion d'Éducation en vue d’un Développement Durable (EDD). De nos jours, l’instruction publique l’a intégrée dans ses objectifs. Ainsi, l’EDD doit faire prendre conscience aux élèves qu’ils ont un rôle à jouer dans la société et qu’il est de leur devoir d’adopter un comportement responsable et de prendre des décisions, en toute connaissance de cause, qui s’inscrivent dans la durabilité. Cependant, nous avons constaté que, dans les classes, l’EDD était majoritairement centrée sur le pilier environnemental du développement durable. Aussi, nous avons choisi de créer une séquence d’enseignement sur le conflit syrien et la migration. Ces thématiques, qui font partie du pilier social du développement durable, sont régulièrement présentes dans l’actualité. Elles font émerger des questions socialement vives qui permettent de faire réfléchir et débattre les élèves. L’analyse des données récoltées nous a permis de nous rendre compte de ce qu’il était possible d’entreprendre avec des élèves au primaire concernant l’EDD et ce qu’il fallait prendre en compte pour rendre les apprentissages optimaux. Elle nous a également permis de mettre évidence le fait que le comportement des enseignantes ainsi que les dispositifs mis en place ont tantôt fait obstacle aux apprentissages visés, tantôt facilité leur acquisition. Grâce à ce travail, nous avons pu comprendre où se situent les enjeux et les clés d’une telle séquence, ce qui nous a permis d’envisager des conditions optimales pour permettre aux élèves de développer des compétences et des savoirs liés au développement durable.

description: The pyridine ring–introduced phenylazomethine dendrimer (PyDPA) was synthesized by a dehydration reaction using titanium(IV) chloride. The ultraviolet–visible absorption and the electrochemical study showed that the introduction of the pyridine ring produces a smaller band gap by increasing the highest occupied molecular orbital level and decreasing the lowest unoccupied molecular orbital level. A crystal of a PyDPA-PdCl2 complex was also prepared. Traditional phenylazomethine dendrimers cannot form a complex with palladium, indicating that PyDPA can potentially coordinate with various metal salts such as Co, Ni, Ru, and Mn and can be used for catalytic or electronic applications.
