description: Abstract: Background: This study, undertaken in Rwanda, aimed to investigate health professionals’ experiences and views on the following topics: current clinical guidelines for ultrasound from second trimester at the clinic, regional and national levels, and adherence to clinical guidelines; medically indicated ultrasound examinations; non-medical use of ultrasound including ultrasounds on maternal request; commercialisation of ultrasound; the value of ultrasound in relation to other clinical examinations in pregnancy; and ultrasound and medicalisation of pregnancy. Methods: A cross-sectional design was adopted. Health professionals providing antenatal care and delivery services to pregnant women in 108 health facilities were invited to complete a survey, which was developed based on the results of earlier qualitative studies undertaken as part of the CROss Country Ultrasound Study (CROCUS). Results: Nine hundred and seven health professionals participated: obstetricians/gynecologists (3.2%,) other physicians (24.5%), midwives (29.7%) and nurses (42.7%). Few physicians reported the existence of clinical guidelines at clinic, regional or national levels in Rwanda, and guidelines were moderately adhered to. Three obstetric ultrasound examinations were considered medically indicated in an uncomplicated pregnancy. Most participants (73.0%) were positive about obstetric ultrasound examinations on maternal request. Commercialisation was not considered a problem, and the majority (88.5%) agreed that ultrasound had contributed to medicalisation of pregnancy. Conclusions: Findings indicate that clinical guidelines for the use of obstetric ultrasound are limited in Rwanda. Non-medically indicated obstetric ultrasound was not considered a current problem at any level of the healthcare system. The positive attitude to obstetric ultrasound examinations on maternal request may contribute to further burden on a maternal health care system with limited resources. It is essential that limited obstetric ultrasound resources are allocated where they are most beneficial, and clearly stated medical indications would likely facilitate this.

description: An efficient technique to simulate turbulent particle-laden flow at high mass loadings within the four-way coupled simulation regime is presented. The technique implements large eddy simulation, discrete phase simulation, a deterministic treatment of inter-particle collisions and an energy-balanced particle agglomeration model. The algorithm to detect inter-particle collisions is such that the computational costs scale linearly with the number of particles present in the computational domain. On detection of a collision, particle agglomeration is tested based on the pre-collision kinetic energy, restitution coefficient and the van der Waals' interactions. The performance of the technique developed is tested by performing parametric studies of the influence the restitution coefficient $(e_{n} = 0.2, 0.4, 0.6$ and $0.8)$, particle size ($d_p = 60, 120, 200$ and $316 μ{m}$), fluid inertia ($Re_τ = 150, 300$ and $590$) and particle concentration ($α_{p} = 5.0 \times 10^{-4}, 1.0 \times 10^{-3}$ and $5.0 \times 10^{-3}$) have on particle-particle interaction events (collision and agglomeration). The results demonstrate that the collision frequency shows a linear dependency on the restitution coefficient, while the agglomeration rate shows an inverse dependence. Collisions among smaller particles are more frequent and efficient in forming agglomerates than those of coarser particles. The particle-particle interaction events show a strong dependency on the shear Reynolds number $Re_τ$, while increasing the particle concentration effectively enhances particle collision and agglomeration. Overall, the sensitivity of the particle-particle interaction events to the selected simulation parameters is found to influence the population and distribution of the primary particles and agglomerates formed.

description: As a member of a team of 84 medical volunteers from the UK, USA, Canada and Russia, I travelled to Kazakhstan in August 2013 to take part in an international medical camp covering the town of Saran and nearby villages. Based in the Ophthalmology and Optometry clinics, I was able to gain a better understanding not only of ocular pathology, but also of the attributes needed for a successful medical camp. In this article, I reflect upon the role of the ophthalmologist, medical student and general volunteer in forming a shared collaboration with local doctors and patients, and consider lessons that can be implemented in daily clinical practice.
The legacy of the Hyksos: a study in cultural memory and identity
Creators: name: Peirce, Laura
Publisher: name: Macquarie University

Subjects: Other education not elsewhere classified

description: The Hyksos era during the Second Intermediate Period had a significant impact on the formation of cultural memory and identity in Ancient Egypt. Specific moments of this era were documented in the Egyptian textual sources from the Second Intermediate Period onwards, and grew increasingly negative towards the Hyksos rulers over time. The specialised descriptions in these texts, however, often contradict the archaeological evidence, and a new approach is needed that can explain the divergences in these two source bases. The present study aims to overcome these issues by re-evaluating the Egyptian textual sources through the concept of cultural memory. The framework of cultural memory represents a unique approach that can allow a fresh understanding of the Hyksos and their legacy to be reached. It intially sets out to determine the frames of experience of the Second Intermediate Period and Expulsion Era, including the events, catastrophes, and obstacles faced by the Thebans and the Hyksos. Following this, the study turns to the non-contemporary accounts to determine features that were altered, added, and omitted. These later texts are then related to their historical and physical context to determine how this influenced the creation of a document and representations of Egyptian identity.
On the weighted $L^2$ estimate for the $k$-Cauchy-Fueter operator and the weighted $k$-Bergman kernel

description: The $k$-Cauchy-Fueter operators, $k=0,1,\ldots$, are quaternionic counterparts of the Cauchy-Riemann operator in the theory of several complex variables. The weighted $L^2$ method to solve Cauchy-Riemann equation is applied to find the canonical solution to the non-homogeneous $k$-Cauchy-Fueter equation in a weighted $L^2$-space, by establishing the weighted $L^2$ estimate. The weighted $k$-Bergman space is the space of weighted $L^2$ integrable functions annihilated by the $k$-Cauchy-Fueter operator, as the counterpart of the Fock space of weighted $L^2$-holomorphic functions on $\mathbb{C}^n$. We introduce the $k$-Bergman orthogonal projection to this closed subspace, which can be nicely expressed in terms of the canonical solution operator, and its matrix kernel function. We also find the asymptotic decay for this matrix kernel function.

description: Rule-based models offer a human-understandable representation, i.e. they are interpretable. For this reason, they are used to explain the decisions of non-interpretable complex models, referred to as black box models. The generation of such explanations involves the approximation of a black box model by a rule-based model. To date, however, it has not been investigated whether the rule-based model makes decisions in the same way as the black box model it approximates. Decision making in the same way is understood in this work as the consistency of decisions and the consistency of the most important attributes used for decision making. This study proposes a novel approach ensuring that the rule-based surrogate model mimics the performance of the black box model. The proposed solution performs an explanation fusion involving rule generation and taking into account the feature importance determined by the selected XAI methods for the black box model being explained. The result of the method can be both global and local rule-based explanations. The quality of the proposed solution was verified by extensive analysis on 30 tabular benchmark datasets representing classification problems. Evaluation included comparison with the reference method and an illustrative case study. In addition, the paper discusses the possible pathways for the application of the rule-based approach in XAI and how rule-based explanations, including the proposed method, meet the user perspective and requirements for both content and presentation. The software created and a detailed report containing the full experimental results are available on the GitHub repository (https://github.com/ruleminer/FI-rules4XAI ).

description: Despite the wide-spread clinical use of schema therapy to treat various disorders, including chronic anxiety, limited research has examined the pathways theorised by Young’s schema model or its viability when treating individuals with social anxiety and social anxiety disorder (SAD). This thesis therefore presents four papers designed to assess the roles of culture, negative parenting practices, temperament, coping styles and the unconscious processing of threatening information in the aetiology of early maladaptive schemas (EMS) and social anxiety. The first study revealed that Chinese (n = 118), Chinese-Australian (n = 120) and Australian (n = 163) students experiencing higher social anxiety symptomatology display higher levels of EMS from Young’s (1999) schema theory related to domain 1: Disconnection and Rejection as well as domain 2: Impaired Autonomy and Performance. Using the same samples, the second study identified EMS as potential partial mediators of the relationship between perceived negative parenting practices (i.e. rejecting and overprotective parenting) and social anxiety, although important cross-cultural differences were identified. The results of the third study involving 360 Australian students indicated that temperament may influence the type of coping style/s some individuals adopt, with more introverted individuals utilising more avoidant strategies, while neuroticism appears to have a stronger relationship with Disconnection and Rejection schemas than coping styles such as avoidance or overcompensation. Finally, the results of the fourth study involving 89 Australian students revealed that there were no significant differences in state social anxiety when comparing groups who received a subliminal Disconnection and Rejection (“Mummy does not love me”), counter-schematic (“Mummy does love me”) or neutral (“Mummy is walking”) cue, however there was a trend in the predicted direction when examining a group who scored high on the Social Interaction Anxiety Scale (SIAS). The role of avoidance was also explored given its relationship with social anxiety. The implications of the findings from each study for both schema therapy theory and treatment concerning social anxiety and SAD are discussed, along with directions for future research.
GPU parallel simulation algorithm of Brownian particles with excluded volume using Delaunay triangulations

description: A novel parallel simulation algorithm on the GPU, implemented in CUDA and C++, is presented for the simulation of Brownian particles that display excluded volume repulsion and interact with long and short range forces. When an explicit Euler-Maruyama integration step is performed to take into account the pairwise forces and Brownian motion, particle overlaps can appear. The excluded volume property brings up the need for correcting these overlaps as they happen, since predicting them is not feasible due to the random displacement of Brownian particles. The proposed solution handles, at each time step, a Delaunay triangulation of the particle positions because it allows us to efficiently solve overlaps between particles by checking just their neighborhood. The algorithm starts by generating a Delaunay triangulation of the particle initial positions on CPU, but after that the triangulation is always kept on GPU memory. We used a parallel edge-flip implementation to keep the triangulation updated during each time step, checking previously that the triangulation was not rendered invalid due to the particle displacements. The algorithm is validated with two models of active colloidal particles. Upon testing the parallel implementation of a long range forces simulation, the results show a performance improvement of up to two orders of magnitude when compared to the previously existing sequential solution.

description: Background: Dyslexia is the most common learning disability, accounts for 5 to 17% of the school-aged children. Dyslexia is defined as an impairment in which the child faces difficulties learning, reading and writing relative to IQ. Objective: The aim of this study was to investigate the central and peripheral visual function in a group of dyslexic children who write from right to left direction. Materials/Patients and Methods: Twenty dyslexic eyes and 20 normal eyes were examined in this study. The visual examinations consisted of measuring distant and near visual acuity, refraction and visual field evaluation using an Octopus 101 automated perimeter. Foveal sensitivity was also measured with static perimetry, and then kinetic perimetry in two target brightness levels: 15 and 20 dB and data were analyzed by SPSS 17 statistical software. Results: Dyslexic and normal children of the study population aged from 7 to 10 years with mean age of 8.5. Mean visible surface area at brightness levels of 15 and 20 dB was significantly different between two groups (p<0.001, p=0.001). In addition, inferior hemifield had the most noticeable differences between groups compared to other hemifields. No significant difference was noted between two groups for other examinations such as visual acuity at distance and near, refractive errors and static foveal sensitivity. Conclusions: Visible surface area was defected in dyslexic children; however, the foveal function was similar to normal individuals. These results support the hypothesis of an impairment of the magnocellular function in dyslexia, whereas the parvocellular pathway is intact.

Getting the Lead out–Does New York City's childhood lead testing make statistical sense?

description: The US has dramatically reduced blood lead levels in children over the past 30 years and that effort continues. New York City (NYC) was an early adopter of lead reduction policies and that effort continues with laws that require all children be tested and with mandatory interventions for those tested blood levels (tbll) greater than 5mg/dL. But there is a statistically interesting story around how current blood level limits are set, the performance of common tests and how to apply common Bayes rule reasoning to publicly available data. The data we have: We have high quality blood lead level (bll) tests applied nation wide (NHANES) for 5,000 children, we have NYC supplied data that provides counts for all children’s tested blood lead level, the number greater than 5mg/dL, 10mg/dL and 15/dL and claims of blood tests that widely vary from sources like FDA applications for blood testing equipment, actual studies of test performance and government testing standards. The data we want: New York city recently dropped the threshold for intervention from 10mg/dL to 5mg/dL. It is an open question what the false positive rate is for these test thresholds with some research suggesting that it is as high as 70%. On the other extreme is an FDA applications for the LeadCare Plus testing device claim a standard deviation of .5 at the 5mg/dL which suggests a very low false positive rate…but that depends on the distribution of actual blls in the NYC population. How we got the data we wanted: This is a simple application of Bayes rule: p(bll > 5t >5) = p(tbll > 5bll>5) p(bll>5)/p(tbll>5) where we don’t know p(bll>5) for NYC. NYC refused to release non-quantized data for tbll under FIOA requests, which if we had, would allow a fairly straightforward determination of false positive rates from tbll test evaluations. But we do have data for the US as a whole in non-quantized form. The paper describes a process of model refinement staring with naive approaches and incrementally modifying our models to better suite NYC data. The final approach, subject to change as we do more work, is to fit national NHANES data with an exponential distribution, assume that similar distributions apply to NYC and recover a believable false positive rate across a range of reported blood test performance. Along the way we show an interesting simple use of the ‘integrate_ode_rk45’ function in Stan and demonstrate Bayesian workflow.

description: As manufacturing processes become increasingly automated, so should tool condition monitoring (TCM) as it is impractical to have human workers monitor the state of the tools continuously. Tool condition is crucial to ensure the good quality of products: Worn tools affect not only the surface quality but also the dimensional accuracy, which means higher reject rate of the products. Therefore, there is an urgent need to identify tool failures before it occurs on the fly. While various versions of intelligent tool condition monitoring have been proposed, most of them suffer from a cognitive nature of traditional machine learning algorithms. They focus on the how to learn process without paying attention to other two crucial issues: what to learn, and when to learn. The what to learn and the when to learn provide self regulating mechanisms to select the training samples and to determine time instants to train a model. A novel tool condition monitoring approach based on a psychologically plausible concept, namely the metacognitive scaffolding theory, is proposed and built upon a recently published algorithm, recurrent classifier (rClass). The learning process consists of three phases: what to learn, how to learn, when to learn and makes use of a generalized recurrent network structure as a cognitive component. Experimental studies with real-world manufacturing data streams were conducted where rClass demonstrated the highest accuracy while retaining the lowest complexity over its counterparts.
Common destiny?: a critical discourse analysis of the independence debate between France and New Caledonia

description: Mainly drawing on Systemic Functional Linguistics (SFL) and pragma-dialectics, this critical discourse analysis explains why the consensus obtained through the independence debate between France and New Caledonia does not constitute the results of a cooperative dialogue between the two discourse communities, but rather a French strategy to maintain a status quo. The study explores how a newly emerging identity for the nation of New Caledonia iscollectively constructed through various discursive acts of negotiation while simultaneously being affected by external power relations. These acts of meaning are firmly placed within the context of the ongoing dialogue between France and New Caledonia concerning the latter’s bid for full independence, a critical issue that formed the impetus for the research project.The study aims to elucidate how three politicians, as representatives of the main stakeholders in the debate, construe their own perceived reality of a “common destiny” and how they depict themselves in terms of power and influence. It looks at their underlying attitudes and concerns and how they express these discursively. It further investigates how they attempt to influence the outcome of the debate and how their social representations translate into reasons for selecting a particular course of action. Finally, it critically investigates what kind of consensus is reached as a result of the negotiation process and questions the reasonableness of the overall debate.Three French discourse samples, two speeches and one interview, are selected for this purpose. Any relevant linguistic features in the excerpts are described using a Hallidayan functional approach in order to explicate various significant lexicogrammatical choices made by the three protagonists: Jean-Marie Tjibaou, Lionel Jospin and Jacques Lafleur. These linguistic findings are then integrated as evidence in a Critical Discourse Analysis (CDA), which follows the logic from Pragma-Dialectics to reconstruct and evaluate the argumentative structure of the political discourse. It is shown how the social representations of each of the communities, together with their imagined realities, motivate and manipulate the consensus and eventually cause a cross-cultural clash.

description: We present our findings in a case of central retinal artery occlusion (CRAO) that developed in a patient while being treated with intravenous cisplatin (CDDP) and etoposide (VP16) for small cell lung cancer. The patient was a 67-year-old woman who had lung lobectomy for small cell lung cancer. She began adjuvant chemotherapy with CDDP and VP16 after the surgery, and after 13 days of chemotherapy, she developed a sudden painless decrease of vision in her left eye. She was referred to Department of Ophthalmology, and our examination found that her decimal visual acuities were 1.0 OD and light perception OS. Fluorescein angiography showed a CRAO in her left eye. Two months later, she had a sharp pain in the left eye because of neovascular glaucoma, and cyclophotocoagulation was immediately performed. Although her visual function did not recover completely (light perception OS), the pain was alleviated after the cyclophotocoagulation. Physical examinations showed no additional abnormalities of the cardiovascular system. Although a CRAO during chemotherapy is extremely rare, ophthalmologists and internists should remember that a CRAO can develop in patients undergoing combined chemotherapy even though other cardiovascular events may not be present.

description: With the continuing drop in the price of memory, Video-on-Demand (VoD) solutions that have so far focused on maximising the throughput of disk units with a minimal use of physical memory may now employ significant amounts of cache memory. The subject of this thesis is the study of a technique to best utilise a memory buffer within such a VoD solution. In particular, knowledge of the streams active on the server is used to allocate cache memory. Stream optimised caching exploits reuse of data among streams that are temporally close to each other within the same clip; the data fetched on behalf of the leading stream may be cached and reused by the following streams. Therefore, only the leading stream requires access to the physical disk and the potential level of service provision allowed by the server may be increased. The use of stream optimised caching may consequently be limited to environments where reuse of data is significant. As such, the technique examined within this thesis focuses on a classroom environment where user progress is generally linear and all users progress at approximately the same rate for such an environment, reuse of data is guaranteed. The analysis of stream optimised caching begins with a detailed theoretical discussion of the technique and suggests possible implementations. Later chapters describe both the design and construction of a prototype server that employs the caching technique, and experiments that use of the prototype to assess the effectiveness of the technique for the chosen environment using `emulated' users. The conclusions of these experiments indicate that stream optimised caching may be applicable to larger scale VoD systems than small scale teaching environments. Future development of stream optimised caching is considered.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: Recently, Amdeberhan, Sellers, and Singh introduced the notion of a generalized cubic partition function $a_c(n)$ and proved two isolated congruences via modular forms, namely, $a_3(7n+4)\equiv 0\pmod{7}$ and $a_5(11n+10)\equiv 0\pmod{11}$. In this paper, we provide another proof of these congruences by using classical $q$-series manipulations. We also give infinite families of congruences for $a_c(n)$ for primes $p\not\equiv 1\pmod{8}$.

Palaeontology, taxonomy and biostratigraphy of Cambrian assemblages from the Pertaoorrta Group, Amadeus Basin, Northern Territory

description: The Amadeus Basin is a large sedimentary province in central Australia that covers an approximate area of 170,000 square km. Despite the known occurrence of fossils from the majority of stratigraphic units within the Cambrian Pertaoorrta Group there is a dearth of published palaeontological data, including no comprehensive biostratigraphy. Presented as part of this thesis is a detailed investigation into three formations spanning the Cambrian Series 2–3 units of the Pertaoorrta Group. The oldest of these, the Tempe Formation and Giles Creek Dolostone have previously been regarded as coeval. Examination of specimens from both drillcore and outcrop material from these two formations revealed a considerable diversity of new and biostratigraphically-informative fossils. The described taxa provide evidence that these two sedimentary units were deposited at different times. The Tempe Formation (in Paper 1) belongs to the Ordian, whereas the fauna from the Giles Creek Dolostone (in Papers 2–4) is distinctly younger and correlates with the overlying early Templetonian. These results suggest that the current regional stratigraphic scheme needs to be amended. The youngest stratigraphic unit examined in this thesis is the Goyder Formation (in Paper 5). The initial age estimates for this formation were based solely on vague reports of the trilobites. Our collections demonstrate that the Goyder Formation contains a highly diverse fossil fauna with at least 20 different trilobite taxa. This assemblage indicates a late Mindyallan age (equivalent to Cambrian Series 3, Guzhangian) within the Glyptagnostus solidotus Zone. Detailed logging and sampling through formations in the Pertaoorrta Group has allowed for precise ages where little to no biostratigraphic data had previously been available.These ages have facilitated the development of a preliminary quantitative biostratigraphy of the Cambrian Series 2–3 portion of the Amadeus Basin, thus permitting more accurate intra and interbasinal correlation.

description: Research-validated multiple-choice questions comprise an easy-to-implement instructional tool that serves to scaffold student learning and formatively assess students knowledge. We present findings from the implementation, in consecutive years, of research-validated multiple-choice question sequence on measurement uncertainty as it applies to two-state quantum systems. This study was conducted in an advanced undergraduate quantum mechanics course, in an online and in-person learning environments in consecutive years. Student learning was assessed after receiving traditional lecture-based instruction in relevant concepts, and their performance was compared with that on a similar assessment given after engaging with the multiple-choice question sequence. We analyze and discuss the similar and differing trends observed in the two modes of instruction.

description: Recently it has been predicted that the Andreev bound state spectrum of 4-terminal Josephson junctions may possess zero-energy Weyl singularities. Using one superconducting phase as a control parameter, these singularities are associated with topological transitions between time-reversal symmetry broken phases with different Chern numbers. Here we show that such topological transitions may also be tuned with a magnetic flux through the junction area in a 3-terminal geometry.

description: Introduction: Anchovy sauce is a known appetizer in many Asian’s cuisines. Based on the bio-physical content of anchovy sauce, there is a possibility of the frequent consumption can affect severity and progression of glaucoma. The aim of this study was to determine the association of anchovy sauce intake in severity and progression of glaucoma. Methods: A cross-sectional study was conducted involving 91 primary glaucoma patients who were compliance and achieved target intraocular pressure, non-smoker and without a family history of glaucoma. Direct face-to-face interview on the dietary recall of anchovy sauce consumption was conducted between May 2013 and December 2013. The complete ocular examination was performed including intraocular pressure measurement. Hoddap-Parrish-Anderson criterion was used to assess the severity of glaucoma based on the latest reliable and reproducible of two consecutive Humphrey visual fields 24-2. The association between anchovy sauce and glaucoma severity was determined using Fisher’s exact test. Multiple logistic regression analysis was performed to determine the association of anchovy sauce intake with glaucoma progression. Results: A total of 46 male and 45 female with primary glaucoma were recruited with a mean age of 66.4 (SD10.1) years old. 56 patients consumed anchovy sauce with 19% occasionally, 44.6% weekly, 16.1% daily and 5.4% in every meal. There was no significant association of anchovy sauce intake with severity and progression of primary glaucoma after a mean of 6.4 years of follow-up.Conclusion: Anchovy sauce has potential protective effect against progression and severity of glaucoma. However, it was not reflected in this study due to small sample size and poor quantification of the amount of anchovy sauce as a condiment to the main dish.

description: Casimir forces are of fundamental interest because they originate from quantum fluctuations of the electromagnetic field. Apart from controlling the Casimir force via the optical properties of the materials, a number of novel geometries have been proposed to generate repulsive and/or non-monotonic Casimir forces between bodies separated by vacuum gaps. Experimental realization of these geometries, however, is hindered by the difficulties in alignment when the bodies are brought into close proximity. Here, using an on-chip platform with integrated force sensors and actuators, we circumvent the alignment problem and measure the Casimir force between two surfaces with nanoscale protrusions. We demonstrate that the Casimir force depends non-monotonically on the displacement. At some displacements, the Casimir force leads to an effective stiffening of the nanomechanical spring. Our findings pave the way for exploiting the Casimir force in nanomechanical systems using structures of complex and non-conventional shapes.

description: Anthropogenic climate change is already having substantial impacts on species, with numerous species undergoing shifts to their range margins. However, many threatened species are restricted to fragmented bushland remnants, and are highly unlikely to be able to shift their range to track the movement of climate zones. In New South Wales, around 440 threatened species have been designated as ‘site-managed species’: their populations are located at discrete sites that require management to ensure the species’ security beyond 2100. Unfortunately, the selection of managed sites did not consider whether climate will remain suitable for species over this time frame. This project interrogated maps of climate suitability under 12 plausible climate scenarios for 238 of these threatened species to (a) assess whether managed sites are likely to retain suitable habitat from now to 2070, and (b) identify whether populations outside of managed sites may be better candidates for site-management, based on the longevity of suitable habitat. Given cumulative threats from climate change and land use change, identifying areas where investment of finite resources will have greatest impact is vital to ensuring the survival of these species.

description: Natural image matting aims to estimate the alpha matte of the foreground from a given image. Various approaches have been explored to address this problem, such as interactive matting methods that use guidance such as click or trimap, and automatic matting methods tailored to specific objects. However, existing matting methods are designed for specific objects or guidance, neglecting the common requirement of aggregating global and local contexts in image matting. As a result, these methods often encounter challenges in accurately identifying the foreground and generating precise boundaries, which limits their effectiveness in unforeseen scenarios. In this paper, we propose a simple and universal matting framework, named Dual-Context Aggregation Matting (DCAM), which enables robust image matting with arbitrary guidance or without guidance. Specifically, DCAM first adopts a semantic backbone network to extract low-level features and context features from the input image and guidance. Then, we introduce a dual-context aggregation network that incorporates global object aggregators and local appearance aggregators to iteratively refine the extracted context features. By performing both global contour segmentation and local boundary refinement, DCAM exhibits robustness to diverse types of guidance and objects. Finally, we adopt a matting decoder network to fuse the low-level features and the refined context features for alpha matte estimation. Experimental results on five matting datasets demonstrate that the proposed DCAM outperforms state-of-the-art matting methods in both automatic matting and interactive matting tasks, which highlights the strong universality and high performance of DCAM.
