description: By analytically continuing the coupling constant $g$ of a coupled quantum theory, one can, at least in principle, arrive at a state whose energy is lower than the ground state of the theory. The idea is to begin with the uncoupled $g=0$ theory in its ground state, to analytically continue around an exceptional point (square-root singularity) in the complex-coupling-constant plane, and finally to return to the point $g=0$. In the course of this analytic continuation, the uncoupled theory ends up in an unconventional state whose energy is lower than the original ground state energy. However, it is unclear whether one can use this analytic continuation to extract energy from the conventional vacuum state; this process appears to be exothermic but one must do work to vary the coupling constant $g$.

Persistence of the flat band in a kagome magnet with dipolar interactions

description: The weathervane modes of the classical Heisenberg antiferromagnet on the kagome lattice constitute possibly the earliest and certainly the most celebrated example of a flat band of zero-energy excitations. Such modes arise from the underconstraint that has since become a defining criterion of strong geometrical frustration. We investigate the fate of this flat band when dipolar interactions are added. These change the nearest-neighbour model fundamentally as they remove the Heisenberg spin-rotational symmetry while also introducing a long- range component to the interaction. We explain how the modes continue to remain approximately dispersionless, while being lifted to finite energy as well as being squeezed: they change their ellipticity described by the ratio of the amplitudes of the canonically conjugate variables comprising them. This phenomenon provides interesting connections between concepts such as constraint counting and self-screening underpinning the field of frustrated magnetism. We discuss variants of these phenomena for different interactions, lattices and dimension.

description: We consider $N$ non-interacting fermions in an isotropic $d$-dimensional harmonic trap. We compute analytically the cumulative distribution of the maximal radial distance of the fermions from the trap center at zero temperature. While in $d=1$ the limiting distribution (in the large $N$ limit), properly centered and scaled, converges to the squared Tracy-Widom distribution of the Gaussian Unitary Ensemble in Random Matrix Theory, we show that for all $d>1$, the limiting distribution converges to the Gumbel law. These limiting forms turn out to be universal, i.e., independent of the details of the trapping potential for a large class of isotropic trapping potentials. We also study the position of the right-most fermion in a given direction in $d$ dimensions and, in the case of a harmonic trap, the maximum momentum, and show that they obey similar Gumbel statistics. Finally, we generalize these results to low but finite temperature.

description: In this article, we give some reviews concerning negative probabilities model and quasi-infinitely divisible at the beginning. We next extend Feller's characterization of discrete infinitely divisible distributions to signed discrete infinitely divisible distributions, which are discrete pseudo compound Poisson (DPCP) distributions with connections to the Lévy-Wiener theorem. This is a special case of an open problem which is proposed by Sato(2014), Chaumont and Yor(2012). An analogous result involving characteristic functions is shown for signed integer-valued infinitely divisible distributions. We show that many distributions are DPCP by the non-zero p.g.f. property, such as the mixed Poisson distribution and fractional Poisson process. DPCP has some bizarre properties, and one is that the parameter $λ$ in the DPCP class cannot be arbitrarily small.

description: Despite the tremendous progress, the need to have large-scale annotated data to train neural network models is, at best, undesirable, and improving the representation power of these models for medical images while preserving intrinsic properties of volumetric medical image modalities is yet under-explored. Obtaining well-annotated labels for medical images requires professional experts and heedful manual labeling, which is expensive and laborious, especially for 3D medical modalities (e.g., MRI and CT). This research addresses the necessity of designing models capable of learning intrinsic properties with limited labels, which is surprisingly not well-explored in the literature.
Liquid Argon TPC Signal Formation, Signal Processing and Hit Reconstruction

description: This document describes the early stage of the reconstruction chain that was developed for the ArgoNeuT and MicroBooNE experiments at Fermilab. These experiments study accelerator neutrino interactions that occur in a Liquid Argon Time Projection Chamber. Reconstructing the properties of particles produced in these interactions requires knowledge of the micro-physics processes that affect the creation and transport of ionization electrons to the readout system. A wire signal deconvolution technique was developed to convert wire signals to a standard form for hit reconstruction, to remove artifacts in the electronics chain and to remove coherent noise.

Introgression between wild and selectively-bred Sydney rock oysters (Saccostrea glomerata)
Creators: name: Thompson, Jessica Ann
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: Oysters provide vital ecosystem services for coastal ecosystems worldwide. Sydney rock oysters (Saccostrea glomerata) are among the most important native Australian oysters. In 1990, a selective breeding program for faster growth rates was implemented for S. glomerata. This has since expanded to include breeding for resistance to winter mortality and QX disease. Selectively-bred oysters are currently farmed in estuaries containing wild oyster populations, providing the opportunity for interbreeding that could alter the genetic variability and structure of the wild populations. Here, we use next-generation genotype by-sequencing to investigate the genetic structures of wild populations and the selectively bred B2 line of S. glomerata. These data are used to test for genetic introgression between the populations at two sites in the Georges River, an estuary in Sydney where selectively bred oysters have been farmed since 1990. Strong genetic partitioning was identified between wild and selectively-bred populations and there was no evidence of sustained gene flow in the form of introgression. Contrary to our expectations, we found significantly higher levels of genetic diversity and heterozygosity in the selectively-bred population than the wild population. These results potentially reflect the impact of population bottlenecks and are relevant to the resilience of this species to environmental change.

Eigenmode orthogonality breaking and deviation from the fluctuation dissipation relation in rotationally dressed nanomechanical oscillators

description: The ultimate sensitivities achieved in force or mass sensing are limited by the employed nanomechanical probes thermal noise. Its proper understanding is critical for ultimate operation and any deviation from the underlying fluctuation dissipation theorem should be carefully inspected. Here we investigate an ultrasensitive vectorial force-field sensor, a singly clamped nanowire oscillating along two quasi frequency degenerated transverse directions. Immersing the nanowire in a non-conservative optical force field causes dramatic modifications of its thermal noise and driven dynamics. In regions of strong vorticity, eigenmodes orientations are distorted and lose their initial orthogonality. Thermal noise spectra strongly deviate from the normal mode expansion and presents an anomalous excess of noise violating the fluctuation dissipation theorem. Our model quantitatively accounts for all observations and underlines the role of non-axial response when patching the fluctuation dissipation relation. These results reveal the intriguing properties of thermal fluctuations in multimode nano-optomechanical systems and the subtleties appearing when performing thermal noise thermometry in such systems. They are also valid in any non-symmetrically coupled dual systems.

description: We explored potential pathways of digital technologies to improve both resilience and sustainability outcomes in grazing systems by investigating the development requirements of virtual herding technologies. We used a Lead User group familiar with virtual herding technology to examine the question “after virtual herding has been successfully adopted, what will the future look like”? This group included agribusiness, industry, corporate farm management, farmers, and science. A brainstorming approach generated ideas. A horizontal prototype was built by clustering ideas into themes of the technology itself, requirements of people, applications, and outcomes, allocated to short-, medium-, and long-term timeframes. Steps required for technology development included: production of a minimum viable product, integration of sensors, and the addition of landscape digitisation. The requirements/impacts on people identified training and awareness, development of skills and labour requirements, and the changing roles of people in the landscape as a progression of change. Applications included productivity, environmental protection, landscape development and enterprise change. A range of requirements were identified within each of these steps and categories. The development of a vision of future technology use provides insight into the complexity of developing digital technologies for sheep and beef farming applications.NZBIDA

description: The authors have shown that nanogranular indium tin oxide (ITO) films, deposited by spray pyrolysis on silicon substrate, demonstrate ultralow thermal conductivity ~ 0.84 +/-0.12 Wm-1K-1 at room temperature. This value is approximately by one order of magnitude lower than that in bulk ITO. The strong drop of thermal conductivity is explained by nanogranular structure and porosity of ITO films, resulting in enhanced phonon scattering on grain boundaries. The experimental results were interpreted theoretically, employing Boltzmann transport equation approach for phonon transport and filtering model for electronic transport. The calculated values of thermal conductivity are in a reasonable agreement with the experimental findings. The presented results show that ITO films with optimal nanogranular structure may be prospective for thermoelectric applications.

Effect of dark counts on single photon heralding with quasi-number-resolving detection schemes

description: We consider photon heralding with quasi-number-resolving detection schemes and account for detection efficiencies and dark count probabilities. With a straightforward formalism, we develop closed-form expressions for the heralding probability, photon number distribution of the resulting heralded state, and fidelity of this heralded state to a single photon state. We calculate that, on the basis of optimizing this fidelity, due to the presence of dark counts there is a maximum number of detection modes worth multiplexing for each combination of efficiency and dark count probability.

description: Automation of tasks on farm has had limited uptake in tools such as auto-weighing and auto-drafting. To develop an understanding of the range of digital tools and the potential to automate tasks in the sheep and beef industry, workshops with end-users were held in the North and South Islands of New Zealand. Current digital technology use on sheep and beef farms included 26 applications representing the categories of communications, administration, monitoring, automated tasks, decision support, prediction, and proof of placement. Obstacles included the amount of time required to either set up or support the technology once in operation. Interoperability and the transfer of information between applications and along the value chain were major obstacles to generating value from combining digital technologies. Automation of data flows along the value chain would provide a significant step forward in the uptake of digital technologies. Digital solutions to aid automation need to be interoperable, with data able to be passed between software solutions, and between users to reduce compliance time and increase accuracy of data handling. The technologies need to be appropriate to be adopted on large scales in an automated way to capture labour-saving benefits. Automation solutions need to translate data into a decision-making form to allow easy interpretation and application of data.NZBIDA

Petrographic, geochemical and age characterisation of crustal xenoliths from Coliban Dam, central Victoria, with implications for the early evolution of southeastern Australia, pre Lachlan Orogen

description: Xenoliths brought up by igneous activity provide insight into underlying geology which may otherwise be inaccessible. In this study whole rock major and trace element geochemistry, zircon U-Pb geochronology and Sr-Nd-Hf isotope data are presented for xenoliths hosted by the Newer Volcanics Spring Hill Complex (~ 3 Ma) at Upper Coliban Dam. These xenoliths provide insight into underlying basement known as the Selwyn Block. The xenolith suite includes two dominant groups: a mafic group with gabbroic texture and composition; and a felsic gneiss with granitic composition and glass bands interlayed between quartz-feldspar rich bands. Rarer xenoliths include trachyandesites, a massive quartz rich meta-sedimentary rock and basaltic icelandites from nearby Stewart Hill. Such diversity reflects the complex nature of the crust and mantle within the region. Zircons separated from the felsic gneiss were examined by backscattered imaging and found to be of the magmatic type, with narrow metamorphic overgrowths. They have a Neoproterozoic crystallisation age of 553 Ma with Hf isotope compositions representative of a mixed source with juvenile and crustal input. Geochemical data support an upper crustal signature. These findings extend on limited knowledge of the Selwyn Block, including a history of formation and deformation. The data also unleashes a potential source for the extensive Lachlan Orogen granites and regional sedimentary terrains. Five zircons from the mafic group xenoliths were also analysed and they provide a timeline of magmatic events within the region. The mafic and intermediate xenoliths share Sr isotope composition with the Newer Volcanic Province but heterogeneous trace element signatures suggest that they are not related.

description: Our ability to model the shapes and strengths of iron lines in the solar spectrum is a critical test of the accuracy of the solar iron abundance, which sets the absolute zero-point of all stellar metallicities. We use an extensive 463-level Fe atom with new photoionisation cross-sections for FeI as well as quantum mechanical calculations of collisional excitation and charge transfer with neutral hydrogen; the latter effectively remove a free parameter that has hampered all previous line formation studies of Fe in non-local thermodynamic equilibrium (NLTE). For the first time, we use realistic 3D NLTE calculations of Fe for a quantitative comparison to solar observations. We confront our theoretical line profiles with observations taken at different viewing angles across the solar disk with the Swedish 1-m Solar Telescope. We find that 3D modelling well reproduces the observed centre-to-limb behaviour of spectral lines overall, but highlight aspects that may require further work, especially cross-sections for inelastic collisions with electrons. Our inferred solar iron abundance is log(eps(Fe))=7.48+-0.04.

description: Significant variables in the calculation of greenhouse gas (GHG) emissions are estimates of birth date and slaughter date, as these alter the amount of time on-farm and hence feed used for animals destined for slaughter. Analysis of Beef + Lamb New Zealand Economic Service farm survey data calculated average birth and slaughter dates for both finishing sheep and beef cattle at a regional scale, from 1990-2019. Data were then used to calculate the potential GHG emissions related to lambs and slaughter cattle, and changes over time, and were compared to current national inventory calculations. There was no significant change in sheep mating date over the 30-year period, with a median lambing date of 10 September. Beef cattle mating date became later over the 30-year period. These resulted in calving dates of 20 September for the 1990-2000 period, and 25 September for the 2010-2019 period.
The proportions of lambs slaughtered by February (early) or October (late), categories used by the National Inventory, have shifted from 84 and 16% respectively in 1990 to 78 and 22% recently. The ages at slaughter of 1–2-year-old heifers and steers were approximately 24 and 35 days younger in 2019 than in 1993 (528 vs 552 days of age at slaughter for heifers and 520 vs 555 days of age at slaughter for steers). The changing proportion of lambs slaughtered early and late had a small effect on total emissions. Later birth dates and earlier slaughter dates have reduced the individual emissions from 1–2-year-old cattle, but individual emissions from older cattle and bulls have changed little over the 27-year period examined.

description: In this article, we consider the problem of estimating the precision matrix when the sample data contains cellwise contamination. For the widely employed methodologies (e.g. Graphical Lasso), using the sample covariance matrix as an input matrix potentially deteriorates the precision matrix estimation performance in the presence of outliers. We propose several robust alternatives for the covariance matrix, which are constructed by combining robust correlation estimators with robust variation measures. Through extensive numerical studies we demonstrate the robust performance of our proposed approaches compared to the standard methods based on the sample covariance matrix. Further, we apply our proposals to a real data application, aimed at studying the optimal portfolio allocations in Shanghai Stock Exchange Composite index. The results show that the proposed alternatives provide desirable out-of-sample performance.

description: We propose a holographic image restoration method using an autoencoder, which is an artificial neural network. Because holographic reconstructed images are often contaminated by direct light, conjugate light, and speckle noise, the discrimination of reconstructed images may be difficult. In this paper, we demonstrate the restoration of reconstructed images from holograms that record page data in holographic memory and QR codes by using the proposed method.

description: Superconductivity of transition metal dichalcogenide $1T$-TiTe$_2$ under high pressure was investigated by the first-principles calculations. Our results show that the superconductivity of $1T$-TiTe$_2$ exhibits very different behavior under the hydrostatic and uniaxial pressure. The hydrostatic pressure is harmful to the superconductivity, while the uniaxial pressure is beneficial to the superconductivity. Superconducting transition temperature $T_C$ at ambient pressure is 0.73 K, and it reduces monotonously under the hydrostatic pressure to 0.32 K at 30 GPa. While the $T_C$ increases dramatically under the uniaxial pressure along $c$ axis. The established $T_C$ of 6.34 K under the uniaxial pressure of 17 GPa, below which the structural stability maintains, is above the liquid helium temperature of 4.2 K. The increase of density of states at Fermi level, the redshift of $F(ω)$/$α^2F(ω)$ and the softening of the acoustic modes with pressure are considered as the main reasons that lead to the enhanced superconductivity under uniaxial pressure. In view of the previously predicted topological phase transitions of $1T$-TiTe$_2$ under the uniaxial pressure [Phys. Rev. B 88, 155317 (2013)], we consider $1T$-TiTe$_2$ as a possible candidate in transition metal chalcogenides for exploring topological superconductivity.

description: Characterising plant-herbivore interactions is important to understanding the processes that influence community structure and ecosystem functioning. Traditional methods used to identify plant-herbivore interactions are being superseded by non-destructive molecular approaches that can infer interactions with greater resolution and accuracy from environmental DNA (e.g. faeces and regurgitate). However, few studies have compared the success of using different sample types and whether they provide similar or contrasting information about species' diet. Here we compared the success of DNA amplification and host plant species identification using restriction fragment length polymorphism (RFLP) applied to faecal and regurgitate samples collected from alpine grasshoppers Paprides nitidus Hutton during a grassland community mesocosm experiment. We found that DNA amplification success was 23% and 86% higher for faecal than regurgitate samples from female and male grasshoppers, respectively. In contrast, successful host plant identification using RFLP was 9% higher for regurgitate than faecal samples. The mean number of host plant species identified per sample (1.40) did not differ between sample types or grasshopper sexes. Of the 136 paired faecal-regurgitate samples, just 41% and 74% produced exactly or partially matching host plant identifications, respectively, indicating that different sample types provided complementary information about herbivore diet. Some plant species were more likely to be identified from faecal samples than expected by chance, and we found that this identification bias skewed towards plant species with higher investment in leaf tissue. We conclude that multiple sample types may be required to fully characterise an invertebrate herbivore species' diet.

description: Nano-mechanical resonators have gained an increasing importance in nanotechnology owing to their contributions to both fundamental and applied science. Yet, their small dimensions and mass raises some challenges as their dynamics gets dominated by nonlinearities that degrade their performance, for instance in sensing applications. Here, we report on the precise control of the nonlinear and stochastic bistable dynamics of a levitated nanoparticle in high vacuum. We demonstrate how it can lead to efficient signal amplification schemes, including stochastic resonance. This work paves the way for the use of levitated nanoparticles as a model system for stochastic bistable dynamics, with applications to a wide variety of fields.

description: In this article, we first discuss a few properties along with limitations of traditional measure of coefficient of dispersion in comparison to the well-known standard measure of variation called the coefficient of variation. To overcome the limitations in the traditional coefficient of dispersion, a new measure of coefficient of dispersion is introduced which is more informative than the conventional one. A new naïve estimator of the newly developed measure of coefficient of dispersion is proposed. The bias and variance expressions for the naïve estimator are derived to the first order of approximation. In the presence of an auxiliary variable, ratio and regression type estimators for estimating the new measure of coefficient of dispersion are also proposed. The bias and the variance expressions to the first order of approximation are derived. A simulation study, using R language, to judge the performance of the proposed ratio and regression type estimators with respect to the naïve estimator is considered. At the end, applications of the proposed ratio and regression type estimators based on real data sets are discussed.
Coexistence of localized and itinerant magnetism in intercalated iron-selenide (Li,Fe)OHFeSe

description: The electronic structure and magnetism of a new magnetic intercalation compound (Li0.8Fe0.2)OHFeSe are investigated theoretically. The electronic structure calculations predict that the Fe in the (Li,Fe)OH intercalated layer is in +2 valence state, i.e. there is electron doping to the FeSe layer, resulting in the shrinking of the Fermi surface (FS) pocket around Gamma and a strong suppression of dynamical spin susceptibility at M in comparison with the bulk FeSe compound. The ground state of the FeSe layer is a striped antiferromagnetic (SAFM) metal, while the (Li,Fe)OH layer displays a very weak localized magnetism, with an interlayer ferromagnetic (FM) coupling between the FeSe and intercalated (Li,Fe)OH layers. Moreover, the (Li,Fe)OH is more than a block layer; it is responsible for enhancing the antiferromagnetic (AFM) correlation in the FeSe layer through interlayer magnetic coupling. We propose that the magnetic spacer layer introduces a tuning mechanism for spin fluctuations associated with superconductivity in iron-based superconductors.
