description: Future astrophysical surveys such as J-PAS will produce very large datasets, which will require the deployment of accurate and efficient Machine Learning (ML) methods. In this work, we analyze the miniJPAS survey, which observed about 1 deg2 of the AEGIS field with 56 narrow-band filters and 4 ugri broad-band filters. We discuss the classification of miniJPAS sources into extended (galaxies) and point-like (e.g. stars) objects, a necessary step for the subsequent scientific analyses. We aim at developing an ML classifier that is complementary to traditional tools based on explicit modeling. In order to train and test our classifiers, we crossmatched the miniJPAS dataset with SDSS and HSC-SSP data. We trained and tested 6 different ML algorithms on the two crossmatched catalogs. As input for the ML algorithms we use the magnitudes from the 60 filters together with their errors, with and without the morphological parameters. We also use the mean PSF in the r detection band for each pointing. We find that the RF and ERT algorithms perform best in all scenarios. When analyzing the full magnitude range of 1521). We use our best classifiers, with and without morphology, in order to produce a value added catalog available at https://j-pas.org/datareleases .

description: A longstanding question in the dual Brunn-Minkowski theory is what are the dual analogues of Federer's curvature measures for convex bodies. The answer to this is provided. This leads naturally to dual versions of Minkowski-type problems, which answer the question of what are necessary and sufficient conditions for a Borel measure to be a dual curvature measure of a convex body. Sufficient conditions, involving measure concentration, are established for the existence of solutions to these problems.

description: We investigate the initiation and early evolution of 12 solar eruptions, including six active region hot channel and six quiescent filament eruptions, which were well observed by the \textsl{Solar Dynamics Observatory}, as well as by the \textsl{Solar TErrestrial RElations Observatory} for the latter. The sample includes one failed eruption and 11 coronal mass ejections, with velocities ranging from 493 to 2140~km~s$^{-1}$. A detailed analysis of the eruption kinematics yields the following main results. (1) The early evolution of all events consists of a slow-rise phase followed by a main-acceleration phase, the height-time profiles of which differ markedly and can be best fit, respectively, by a linear and an exponential function. This indicates that different physical processes dominate in these phases, which is at variance with models that involve a single process. (2) The kinematic evolution of the eruptions tends to be synchronized with the flare light curve in both phases. The synchronization is often but not always close. A delayed onset of the impulsive flare phase is found in the majority of the filament eruptions (5 out of 6). This delay, and its trend to be larger for slower eruptions, favor ideal MHD instability models. (3) The average decay index at the onset heights of the main acceleration is close to the threshold of the torus instability for both groups of events (although based on a tentative coronal field model for the hot channels), suggesting that this instability initiates and possibly drives the main acceleration.

description: In contrast to research that examines the effects of socioeconomic status (SES) and bilingualism on development by comparing clearly disparate groups, the present study investigated the role of subtle differences in these experiences for their joint impact on performance on a verbal fluency task and an executive function (EF) task. The study involved 234 6-year-old children who were assessed for nonverbal intelligence and English vocabulary; parents completed a questionnaire providing demographic information and details about children’s language experiences. Children were assigned continuous scores for SES based on parents’ education and for bilingualism based on experience with non-English languages. Both continuous scores were normally distributed, so median split calculations created binary groups indicating relative levels of SES (high vs. middle) and bilingualism (more monolingual vs. more bilingual). For verbal fluency, there were no group differences in semantic fluency but phonological fluency was performed better by children from higher SES backgrounds, both in between-group and continuous analyses. For EF, the between-group analysis revealed an interaction in which bilingual children in the higher SES group outperformed all other children; nonetheless, a positive relation between degree of bilingualism and EF was significant across the whole sample. Thus, both SES and bilingualism affected language and cognitive development with limiting conditions for each experience. The discussion considers the effect of these subtle differences in SES and bilingual experience on development of essential cognitive abilities, the relation between these results and previous research, and the importance of how groups are defined in research addressing individual differences.

description: We study the T=0 crossover from the BCS superconductivity to Bose-Einstein condensation in the attractive Hubbard Model within dynamical mean field theory(DMFT) in order to examine the validity of Hartree-Fock-Bogoliubov (HFB) mean field theory, usually used to describe this crossover, and to explore physics beyond it. Quantum fluctuations are incorporated using iterated perturbation theory as the DMFT impurity solver. We find that these fluctuations lead to large quantitative effects in the intermediate coupling regime leading to a reduction of both the superconducting order parameter and the energy gap relative to the HFB results. A qualitative change is found in the single-electron spectral function, which now shows incoherent spectral weight for energies larger than three times the gap, in addition to the usual Bogoliubov quasiparticle peaks.

description: The ACIAR-managed project CS1/1996/013, Herbicide-resistant weeds of wheat in India and Australia: integrated management, was designed to find a long-term method of control of Phalaris minor, a problem weed of the rice–wheat cropping system of north-western India. By 1993, the weed had developed resistance to isoproturon, a herbicide which had delivered effective weed control for 15 years. The short-term solution, implemented before the ACIAR project commenced, involved identification and registration of a new set of herbicides. But these new herbicides were expensive. To ensure high adoption they needed to be combined with changes in wheat-growing techniques that would provide cost savings to help farmers pay for them. And to avoid the re-emergence of chemical resistance, they needed to be used sparingly as one element in a broader approach to weed management. The project team used these circumstances to field-test and encourage adoption of zero tillage, a technology that agronomists had been advocating for many years, but which had failed to capture the interest of Indian farmers. Zero tillage has the potential to deliver big cost savings. In addition, it provides prospects for yield increases by allowing early sowing of wheat and avoiding soil degradation. Project research established that zero tillage also provided effective weed control with only a moderate reliance on chemicals, making the re-emergence of herbicide resistance remote. We calculate a gain to the Indian economy of around $1800 million in net present value terms over the next 30 years from the adoption of zero tillage to control Phalaris minor infestation in the rice–wheat areas of north-western India. This leads to an extremely high ratio of benefits to project costs. Zero tillage by itself is clearly a profitable technology. It does not need a weed problem to justify its introduction. Without the ACIAR project, zero tillage would have been introduced to the region, though somewhat later than what has occurred. On the assumption that the ACIAR project has advanced the adoption profile of zero tillage by 3 years, we calculate gains that can be attributed to ACIAR’s role of $238 million in net present value terms over the next 30 years. This gain has been achieved with total expenditures on the ACIAR-managed project amounting to only $1.3 million in present values.

description: Extreme mass ratio inspirals (EMRIs), i.e. binary systems comprised by a compact stellar-mass object orbiting a massive black hole, are expected to be among the primary gravitational wave (GW) sources for the forthcoming LISA mission. The astrophysical processes leading to the formation of such systems still remain poorly understood, resulting into large uncertainties in the predicted cosmic rate of these sources, spanning at least three orders of magnitude. As LISA can individually resolve mostly EMRIs up to $z\gtrsim1$, the ensemble of signals below its detection threshold will add up incoherently forming an unresolved confusion noise, which can be formally described as a stochastic background. We perform an extensive study of this background by considering a collection of astrophysically motivated EMRI formation scenarios, spanning current uncertainties. We find that, for most astrophysical models, this signal is easily detectable by LISA, with signal to noise ratios of several hundreds. In fiducial EMRI models -- predicting hundreds of EMRI detections during mission operations -- the background level is comparable to the LISA noise, affecting the performance of the instrument around 3 mHz. In extreme cases, this background can even "erase" the whole LISA sensitivity bucket in the 2-10 mHz frequency range. This points to the need of a better understanding of EMRIs' astrophysics for a full assessment of the LISA mission potential.

description: This report sets out some broad ideas about how poverty evaluation could be conducted for ACIAR research projects. As with good benefit–cost analysis, there are good practices that need to be observed when undertaking poverty analysis. While poverty is a broad concept, and can be addressed through many means, these need to be grounded in some common understanding of the economics of poverty. This report is concerned mostly with quantitative evaluation, in the same sense that current ACIAR project evaluations are quantitative. That is, it is concerned with saying something about the order of magnitude of the effects of the project. Of course, qualitative analysis is important, and in most cases is a prelude to quantification — there is little point quantifying if you don’t understand what you are talking about. Quantification, however, provides a discipline and focus for qualitative speculation and provides an important extra dimension when comparing the effects of different projects. When quantifying, there are many sensible approaches that could be adopted. We will focus here on approaches that are broadly consistent with the current approaches to benefit–cost analysis and that could readily be used to augment those approaches. The report begins by reviewing some basic notions of poverty (Chapter 2) and then goes on (Chapter 3) to discuss in principle the ways that agricultural research could influence poverty. Chapter 4 explains, with the use of some examples, a range of analytical approaches that could be taken, and Chapter 5 draws some specific implications for ACIAR.

description: The galaxy group NGC 5044 consists of a luminous giant elliptical galaxy surrounded by a cluster of approximately 160 low luminosity and dwarf galaxies, mostly of early type. The cumulative projected radial distribution of dwarf galaxies in the NGC 5044 group, unlike distributions of more luminous galaxies in rich clusters, does not follow a projected dark matter (NFW) profile. Instead, a deficiency or absence of low luminosity galaxies is apparent in NGC 5044 within about 350 kpc, about one third of the current group virial radius. Most of the dwarf galaxies identified in NGC 5044 entered the virial radius at redshifts less than about 2 or 3, and very few entered at higher redshifts. The peculiar, non-NFW shape of the projected cumulative dwarf galaxy distribution in NGC 5044 within 350 kpc resembles the characteristic shallow cumulative distribution of dark subhalos that are also known to be relatively young. Dynamical friction is unlikely to explain the apparent lack of group member galaxies at small radii in NGC 5044.

description: We develop a perturbative model to treat the off-diagonal components in the Hartree-Fock-Bogoliubov (HFB) transformation matrix, which are neglected in the BCS approximation. Applying the perturbative model to a weakly bound nucleus $^{84}$Ni, it is shown that the perturbative approach reproduces well the solutions of the HFB method both for the quasi-particle energies and the radial dependence of quasi-particle wave functions. We find that the non-resonant part of the continuum single-particle state can acquire an appreciable occupation probability when there exists a weakly bound state close to the Fermi surface. This result originates from the strong coupling between the continuum particle state and the weakly bound state, and is absent in the BCS approximation. The limitation of the BCS approximation is pointed out in comparison with the HFB and the present perturbative model.

description: This paper investigates the stochastic moving target encirclement problem in a realistic setting. In contrast to typical assumptions in related works, the target in our work is non-cooperative and capable of escaping the circle containment by boosting its speed to maximum for a short duration. Considering the extreme environment, such as GPS denial, weight limit, and lack of ground guidance, two agents can only rely on their onboard single-modality perception tools to measure the distances to the target. The distance measurement allows for creating a position estimator by providing a target position-dependent variable. Furthermore, the construction of the unique distributed anti-synchronization controller (DASC) can guarantee that the two agents track and encircle the target swiftly. The convergence of the estimator and controller is rigorously evaluated using the Lyapunov technique. A real-world UAV-based experiment is conducted to illustrate the performance of the proposed methodology in addition to a simulated Matlab numerical sample.

description: The Mama Lus Frut scheme was established to increase the productivity of smallholder palm-oil plantations in Papua New Guinea. ACIAR project ASEM/1999/084, ‘Improving Productivity of the Smallholder Oil Palm Sector in Papua New Guinea: a Study of Biophysical and Socioeconomic Interactions’, included an assessment of the impact of the Mama Lus Frut scheme. The ACIAR project was also involved in refining and extending the scheme both geographically and demographically, including extending it from women family members to the community at large. This report describes the effect of the scheme (and therefore indirectly the effect of the ACIAR project) on reducing poverty for smallholder oil-palm producers. It draws upon information from a socioeconomic study of oilpalm schemes in Papua New Guinea (Koczberski et al. 2001) and figures provided by George Curry of Curtin University of Technology, Bentley, Western Australia. A high rate of fruit wastage was endemic in the oil-palm industry before the scheme, as fruit that fell from the main bunches was left on the ground to rot. Collecting loose fruit is considered women’s work. The returns from the sale of the fruit collected would be recorded on the man of the household’s payment card (now known as the ‘papa card’); the woman of the house would often not receive any money from the fruit she harvested. Thus, women preferred to spend their time growing vegetables and selling these at the market, where they could keep the returns of their labour. The result of this is that there was no incentive for anyone to collect and sell the loose fruit. It should be noted that there are two classifications of smallholders involved in the scheme: Land Settlement Scheme smallholders and Village Oil Palm smallholders. The region of Hoskins primarily consists of Land Settlement Scheme lots, while Popondetta contains mainly Village Oil Palm smallholders. The demographics of the two schemes tend to differ in some aspects. This report concentrates primarily on Land Settlement Scheme smallholders in the Hoskins area on the New Guinea Islands.

description: We present results of a computation of NLO QCD corrections to the production of an off-shell top--antitop pair in association with an off-shell $\text{W}^+$ boson in proton--proton collisions. As the calculation is based on the full matrix elements for the process $\text{p}\text{p}\to {\text{e}}^+ν_{\text{e}}\,μ^-\barν_μ\,τ^+ν_τ\,{\text{b}}\,\bar{\text{b}}$, all off-shell, spin-correlation, and interference effects are included. The NLO QCD corrections are about $20\%$ for the integrated cross-section. Using a dynamical scale, the corrections to most distributions are at the same level, while some distributions show much larger $K$-factors in suppressed regions of phase space. We have performed a second calculation based on a double-pole approximation. While the corresponding results agree with the full calculation within few per cent for integrated cross-sections, the discrepancy can reach $10\%$ and more in regions of phase space that are not dominated by top--antitop production. As a consequence, on-shell calculations should only be trusted to this level of accuracy.

Canadian populations and melanin biosynthetic genes of Ceratocystis resinifera
Creators: name: Loppnau, Peter Arne
Publisher: name: University of British Columbia
Year: 2009

description: This thesis extends our knowledge concerning the sapstain fungus Ceratocystis resinifera. The presented work covers two subject areas of research. The first reports the collection and identification of Canadian populations of C. resinifera, while the second reports the isolation and characterization of three genes encoding melanin biosynthetic enzymes. C. resinifera was identified as a deep stain fungus present in softwood logs across Canada. It was a generalist, not specific to any one-host tree since both Pinus and Picea species were colonized. Molecular methods (PCR-RFLP) were used to positively identify the collected isolates. DNA sequence information indicated that there was low genetic variability within these Canadian populations of C. resinifera, and this conclusion was confirmed by our collaborators using RAPD analysis of genomic DNA markers (Morin 2002). Three genes, PKS1, 4HNR, and SD1, encoding for melanin biosynthetic enzymes were isolated. PKS1 encoded for a typical type I fungal pentaketide synthase responsible for 1,3,6,8,- tetrahydroxynaphthalene synthesis. 4HNR encoded for a 1,3,6,8,-tetrahydroxynaphthalene reductase and the gene product was also found to have 1,3,8,-tetrahydroxynaphthalene reductase activity in Magneporthe grisea. SD1 encoded for a scytalone dehydratase. The pigment responsible for wood stain in C. resinifera was confirmed to be DHNmelanin. Targeted disruption of PKS1 resulted in strains with an albino phenotype. The addition of scytalone to disrupted strains and the recovery of pigmentation confirmed that the genetic lesion occurred in an enzyme at the beginning of a DHN-melanin pathway. Other than the loss of pigmentation, no secondary effects on the growth of albino strains were observed. The presented work should stimulate further research into the molecular genetics of melanin production in sapstain fungi. Also, it should contribute to our knowledge concerning the pigmentation and population structure of C. resinifera, which we propose as a candidate organism for biological control to prevent sapstain in Canadian softwood logs.
Accelerated rejuvenation in metallic glasses subjected to elastostatic compression along alternating directions

description: The influence of static stress and alternating loading direction on the potential energy and mechanical properties of amorphous alloys is investigated using molecular dynamics simulations. The model glass is represented via a binary mixture which is first slowly annealed well below the glass transition temperature and then subjected to elastostatic loading either along a single direction or along two and three alternating directions. We find that at sufficiently large values of the static stress, the binary glass becomes rejuvenated via collective, irreversible rearrangements of atoms. Upon including additional orientation of the static stress in the loading protocol, the rejuvenation effect is amplified and the typical size of clusters of atoms with large nonaffine displacements increases. As a result of prolonged mechanical loading, the elastic modulus and the peak value of the stress overshoot during startup continuous compression become significantly reduced, especially for loading protocols with alternating stress orientation. These findings are important for the design of novel processing methods to improve mechanical properties of metallic glasses.

description: Practitioners frequently observe that pruning improves model generalization. A long-standing hypothesis based on bias-variance trade-off attributes this generalization improvement to model size reduction. However, recent studies on over-parameterization characterize a new model size regime, in which larger models achieve better generalization. Pruning models in this over-parameterized regime leads to a contradiction -- while theory predicts that reducing model size harms generalization, pruning to a range of sparsities nonetheless improves it. Motivated by this contradiction, we re-examine pruning's effect on generalization empirically. We show that size reduction cannot fully account for the generalization-improving effect of standard pruning algorithms. Instead, we find that pruning leads to better training at specific sparsities, improving the training loss over the dense model. We find that pruning also leads to additional regularization at other sparsities, reducing the accuracy degradation due to noisy examples over the dense model. Pruning extends model training time and reduces model size. These two factors improve training and add regularization respectively. We empirically demonstrate that both factors are essential to fully explaining pruning's impact on generalization.

description: A mixed-methods, multiple-stage approach was used to obtain data on how gender and wealth affected participation in community groups in Meru, Kenya, and how men and women farmers obtain and diffuse agricultural information. Research techniques included participant observation, documentary analysis, semi-structured interviews, social mapping, group timelines, and structured questionnaires. Dairy-goat farmer groups were interviewed for the study. Qualitative data provided baseline information, and helped in the formulation of research questions. Quantitative data were analyzed using contingency tables, descriptive statistics, correlations, tests of significance, and regression. Factors that affected participation in different types of groups included household composition, age, and gender. Women made up 59 percent of the dairy-goat group (DGG) members, with the DGG project encouraging women’s participation. Women made up 76 percent of DGG treasurer positions; 43 percent of secretary positions, and 30 percent of chairperson positions. Gender also influenced participation in clan groups, water groups, and merry-go-round (savings and loans) groups. Wealth did not appear to have a significant effect on participation in community groups. Extension was the most important information source for both men and women farmers. However, church and indigenous knowledge (passed on from parents) seemed more important to women. Both men and women mentioned other farmers, groups, and “baraza” (public meetings used to make announcements and diffuse information) as important information sources, but they rated them at different levels of importance. Men were diffusing information to greater numbers of people than women, although men and women diffused to similar sources. This study shows that because men and women traditionally participate in different types of groups and receive agricultural information from different sources, development agencies must target different types of groups and institutions to reach men, women, or poor farmers. Mechanisms should be developed to include women, the poor, and other targeted groups in community associations that provide market and other income-earning opportunities.

description: A Laser-stimulated synthesis of large silver nanoaggregates consisting of hundreds to thousands of nanoparticles is investigated. It is shown that the morphology of the synthesized nanostructures can be controlled with light and monitored via the evolution of the colloid absorption spectra. A solution method is demonstrated that enables production of a bulk amount of metal nanoaggregates, which are of paramount importance for subwavelength concentration and dramatic enhancement of the electromagnetically-induced processes at the nanoscale.

description: Emerging unsupervised implicit neural representation (INR) methods, such as NeRP, NeAT, and SCOPE, have shown great potential to address sparse-view computed tomography (SVCT) inverse problems. Although these INR-based methods perform well in relatively dense SVCT reconstructions, they struggle to achieve comparable performance to supervised methods in sparser SVCT scenarios. They are prone to being affected by noise, limiting their applicability in real clinical settings. Additionally, current methods have not fully explored the use of image domain priors for solving SVCsT inverse problems. In this work, we demonstrate that imperfect reconstruction results can provide effective image domain priors for INRs to enhance performance. To leverage this, we introduce Self-prior embedding neural representation (Spener), a novel unsupervised method for SVCT reconstruction that integrates iterative reconstruction algorithms. During each iteration, Spener extracts local image prior features from the previous iteration and embeds them to constrain the solution space. Experimental results on multiple CT datasets show that our unsupervised Spener method achieves performance comparable to supervised state-of-the-art (SOTA) methods on in-domain data while outperforming them on out-of-domain datasets. Moreover, Spener significantly improves the performance of INR-based methods in handling SVCT with noisy sinograms. Our code is available at https://github.com/MeijiTian/Spener.

description: Manufacturers of smart home Internet of Things (IoT) devices are increasingly adding voice assistant and audio monitoring features to a wide range of devices including smart speakers, televisions, thermostats, security systems, and doorbells. Consequently, many of these devices are equipped with microphones, raising significant privacy concerns: users may not always be aware of when audio recordings are sent to the cloud, or who may gain access to the recordings. In this paper, we present the LeakyPick architecture that enables the detection of the smart home devices that stream recorded audio to the Internet without the user's consent. Our proof-of-concept is a LeakyPick device that is placed in a user's smart home and periodically "probes" other devices in its environment and monitors the subsequent network traffic for statistical patterns that indicate audio transmission. Our prototype is built on a Raspberry Pi for less than USD40 and has a measurement accuracy of 94% in detecting audio transmissions for a collection of 8 devices with voice assistant capabilities. Furthermore, we used LeakyPick to identify 89 words that an Amazon Echo Dot misinterprets as its wake-word, resulting in unexpected audio transmission. LeakyPick provides a cost effective approach for regular consumers to monitor their homes for unexpected audio transmissions to the cloud.
Quantum corrections to the phase diagram of heavy-fermion superconductors

description: The competition between magnetism and Kondo effect is the main effect determining the phase diagram of heavy fermion systems. It gives rise to a quantum critical point which governs the low temperature properties of these materials. However, experimental results made it clear that a fundamental ingredient is missing in this description, namely superconductivity. In this paper we make a step forward in the direction of incorporating superconductivity and study the mutual effects of this phase and antiferromagnetism in the phase diagram of heavy fermion metals. Our approach is based on a Ginzburg-Landau theory describing superconductivity and antiferromagnetism in a metal with quantum corrections taken into account through an effective potential. The proximity of an antiferromagnetic instability extends the region of superconductivity in the phase diagram and drives this transition into a first order one. On the other hand superconducting quantum fluctuations near a metallic antiferromagnetic quantum critical point gives rise to a first order transition from a low moment to a high moment state in the antiferromagnet. Antiferromagnetism and superconductivity may both collapse at a quantum bicritical point whose properties we calculate.

description: This study addresses the challenge of handling values below the detection limit (DL) in environmental and toxicological data analysis. Traditional imputation methods, such as substituting censored values with constants, often distort data distributions and lead to unreliable statistical outcomes. To improve accuracy, the study explores two advanced imputation techniques: log-normal and weighted exponential imputation, which better reflect the skewed patterns typical of environmental contamination and exposure levels. Additionally, a third approach, Alpha-Based Hybrid Imputation, is introduced, combining the strengths of both log-normal and weighted exponential methods. This hybrid technique enhances the precision of imputed values, particularly for datasets with values clustered near the DL. Python code for all three methods is presented, and the imputation process, along with validation, is further documented in separate Excel files for 32 metals.
