description: In this series of papers, we employ several machine learning (ML) methods to classify the point-like sources from the miniJPAS catalogue, and identify quasar candidates. Since no representative sample of spectroscopically confirmed sources exists at present to train these ML algorithms, we rely on mock catalogues. In this first paper we develop a pipeline to compute synthetic photometry of quasars, galaxies and stars using spectra of objects targeted as quasars in the Sloan Digital Sky Survey. To match the same depths and signal-to-noise ratio distributions in all bands expected for miniJPAS point sources in the range $17.5\leq r<24$, we augment our sample of available spectra by shifting the original $r$-band magnitude distributions towards the faint end, ensure that the relative incidence rates of the different objects are distributed according to their respective luminosity functions, and perform a thorough modeling of the noise distribution in each filter, by sampling the flux variance either from Gaussian realizations with given widths, or from combinations of Gaussian functions. Finally, we also add in the mocks the patterns of non-detections which are present in all real observations. Although the mock catalogues presented in this work are a first step towards simulated data sets that match the properties of the miniJPAS observations, these mocks can be adapted to serve the purposes of other photometric surveys.

description: We introduce the notion of a special monopole class on a four-manifold. This is used to prove restrictions on the smooth structures of Einstein manifolds. As an application we prove that there are Einstein four-manifolds which are simply connected, spin, and satisfy the strict Hitchin--Thorpe inequality, and which are homeomorphic to manifolds without Einstein metrics. In the Appendix, written with J. Wehrheim, we use special monopole classes to discuss the classification of Ricci-flat four-manifolds.

title: Climate change as a structural social problem
Creators: name: Fedoseev, Max
Publisher: name: The Australian National University
Year: 2025

description: The world is failing to avert dangerous climate change. Facing a real possibility of environmental collapse, we will do well to take a step back and reflect on the nature of the problem and the task of addressing it. That is what I attempt in this thesis. I analyse climate change as a structural social problem. The analysis produces methodological, political, and moral insights which I think are important for addressing the problem. I begin by developing a comprehensive account of structural social problems and their mechanisms, explaining how social structures systematically produce harms. I illustrate the account by sketching a structural diagnosis of climate change. I then apply these theoretical and diagnostic tools to reflect on the task of addressing the problem. First, I criticise a dominant philosophical methodology for a lack of attention to structural context and propose an alternative, structural approach. Second, I flesh out the task of addressing structural problems and the moral aims it involves. Third, I identify a common implementation problem that any proposed solution to climate change must overcome: the inability of key agents to take required action due to the structural constraints within which they operate. I argue that our best chance at overcoming this 'problem of agency' lies with a powerful social movement. Finally, I develop and defend Iris Marian Young's idea that ordinary citizens ought to engage in political action to transform harmful social structures in virtue of their contribution to those structures. A powerful social movement is not only politically necessary for meaningful climate action but is also morally required. The contribution of the thesis is twofold. On the one hand, it's an applied project that produces methodological, political, and moral insights that I hope are important and useful for the practical task of averting climate change. On the other hand, the thesis makes a general theoretical contribution that furthers our understanding of structural social problems and offers tools for analysing them and designing solutions.

We are able to implement Thiemann's version of the Hamiltonian constraint. We discuss its action including the matrix elements and its solutions. This provides a 2+1 dimensional arena to test ideas for the dynamics of quantum gravity and opens the possibility of quantum studies of rotating black hole spacetimes.

description: We explore the character of a novel set of ``field-linked'' states that were predicted in [A. V. Avdeenkov and J. L. Bohn, Phys. Rev. Lett. 90, 043006 (2003)]. These states exist at ultralow temperatures in the presence of an electrostatic field, and their properties are strongly dependent on the field's strength. We clarify the nature of these quasi-bound states by constructing their wave functions and determining their approximate quantum numbers. As the properties of field-linked states are strongly defined by anisotropic dipolar and Stark interactions, we construct adiabatic surfaces as functions of both the intermolecular distance and the angle that the intermolecular axis makes with the electric field. Within an adiabatic approximation we solve the 2-D Schrodinger equation to find bound states, whose energies correlate well with resonance features found in fully-converged multichannel scattering calculations.
Polymeric nematics of associating rods: phase behavior, chiral propagation and elasticity

Year: 2019
Subjects: subject: Soft Condensed Matter (cond-mat.soft)
subject: FOS: Physical sciences

description: Rod-shaped colloids with attractive tips can form linear aggregates that may subsequently undergo hierarchical self-assembly into nematic fluids. Inspired by recent modelling efforts on chromonic liquid crystals, composed of discotic building blocks, we formulate a second-virial theory for reversible supramolecular rods. Unlike chromonics, these systems are capable of forming stable nematic phases in the high-temperature, monomeric limit in the absence of polymerization. Changing the tip potential from attractive to repulsive thus enables a smooth crossover from a monomeric to a polymeric nematic fluid. We analyze the isotropic-nematic phase behavior for both regimes and address the nematic elastic properties. The theory accounts for the molecular flexibility and chirality of the filaments and respects the intrinsic chain-length dependence of nematic order. We also discuss the impact of polymerization inhibitors on the phase behavior in the polymeric regime and find that the inhibitors cause a marked narrowing of the isotropic-nematic biphasic region, and generate reentrance nematization as well as a mass density inversion of the coexisting phases. We finally discuss the elastic moduli of rod-based polymeric nematics by qualitative comparing their elastic anisotropies with those of chromonic liquid crystals and other nanoparticle-based nematics.

description: We show that a suitable interaction between a scalar field and a matter fluid in a spatially homogeneous and isotropic spacetime can drive the transition from a matter dominated era to an accelerated expansion phase and simultaneously solve the coincidence problem of our present Universe. For this purpose we study the evolution of the energy density ratio of these two components. We demonstrate that a stationary attractor solution is compatible with an accelerated expansion of the Universe. We extend this study to account for dissipation effects due to interactions in the dark matter fluid. Finally, Type Ia supernovae and primordial nucleosynthesis data are used to constrain the parameters of the model.

description: We report on the first integration of novel magnetic microcalorimeter detectors (MMCs), developed within SPARC (Stored Particles Atomic Physics Research Collaboration), into the experimental environment of storage rings at GSI, Darmstadt, namely at the electron cooler of CRYRING@ESR. Two of these detector systems were positioned at the 0$^\circ$ and 180$^\circ$ view ports of the cooler section to obtain high-resolution x-ray spectra originating from a stored beam of hydrogen-like uranium interacting with the cooler electrons. While previous test measurements with microcalorimeters at the accelerator facility of GSI were conducted in the mode of well-established stand-alone operation, for the present experiment we implemented several notable modifications to exploit the full potential of this type of detector for precision x-ray spectroscopy of stored heavy ions. Among these are a new readout system compatible with the multi branch system data acquisition platform of GSI, the synchronization of a quasi-continuous energy calibration with the operation cycle of the accelerator facility, as well as the first exploitation of the maXs detectors' time resolution to apply coincidence conditions for the detection of photons and charge-changed ions.

description: Single equation estimates of production models usually are justified by the assumption that production inputs are chosen as part of a one-period decision problem. Yet, most production decisions in agriculture are made sequentially. In this paper the farmer's optimal input choices are modeled as optimal controls in a stochastic control problem. A two-period Cobb-Douglas example is used to show that sequential solutions to production problems may yield models which require either single equation or simultaneous equation estimators. Functional separability, stochastic specification, and behavior under uncertainty are discussed in the context of dynamic production models.
Quadrics for structuring space-time wavepackets

description: Space-time light structuring has emerged as a very powerful tool for controlling the propagation dynamics of pulsed beam. The ability to manipulate and generate space-time distributions of light has been remarkably enhanced in past few years, letting envision applications across the entire spectrum of optics. Space-time optical wavepackets manipulated up to now are usually two-dimensional objects (one space dimension and time) whose mode-resolved spectra lie in a conical section. Using simple symmetry and invariance principles, we show that such wavepackets are particular cases of more general three-dimensional structures whose space-time frequencies lie on quadric surfaces. Our proposed framework allows here classifying space-time wavepackets localized in all dimensions, in any group-velocity dispersion regime, both in bulk and waveguides. Particular emphasis is placed on orbital angular momentum-carrying space-time wavepackets. This unprecedented theoretical approach opens the way for versatile synthesizing of space-time optics.

description: In battery electric buses (e-buses), the substantial energy consumption of the heating, ventilation, and air conditioning (HVAC) system can cause significant reductions of the available travel range. Additionally, HVAC systems are often operated at higher levels than what required for the thermal comfort of the passengers. Therefore, this paper proposes a method to experimentally investigate the influence of the HVAC system on the energy consumption and thermal comfort in a 12m e-bus. An appropriate thermal comfort model is identified and the required climatic input parameters are selected and measured with self-developed sensor stations. The energy consumption of the e-bus, the state of charge (SoC) of the battery and the available travel range are measured by an embedded data logger. Climatic measurements are then performed with heating on and off on a Berlin bus line in winter conditions. The results show that the energy consumption of the e-bus is increased by a factor of 1.9 with heating on, while both the SoC and travel range are reduced accordingly. Comparing the thermal comfort with heating on and off, a decrease from “comfortable” to “slightly uncomfortable but acceptable” is observed.

description: Legume plants have the ability to fix atmospheric nitrogen symbiotically with the association of Rhizobium that inhabits the root nodules. Cletoria ternatea L. is a legume, which grows naturally in dry and less fertile lands. It has the ability to fix nitrogen even under harsh environmental conditions. The present study was aimed at screening the Rhizobial strains of Cletoria ternatea L which have the ability to tolerate high salinity, high temperature, drought, and broad pH range and identifying and differentiating the best tolerant strains at molecular level using PCR amplified Enterobacterial Repetitive Intergenic Consensus (ERIC) profiling. Bacterial colonies were isolated from root nodules, which were collected from five different districts of Sri Lanka namely Jaffna (J), Trincomalee (T), Vavuniya (V), Mannar (M) and Kandy (K). Fresh nodules were collected and pure cultures were obtained by using ½ Lupin agar medium. Total of 25 pure colonies representing the five districts (5 from each district) were selected. These cultures were grown in ½ Lupin broth ranging the temperature from 25℃ to 60℃, NaCl concentrations 1-5%, pH from 2-10, and PEG from 10-30%, separately. Growth of the cultures were tested by measuring the optical density at 600 nm. From physiological characterisation, fourteen best high tolerant strains were selected for ERIC profiling. Among these 14 isolates, M3, and V3 isolates exhibited good tolerance to the temperature range from 25℃ to 60℃, NaCl concentration range from 1-5%, pH range from 2-10 and PEG concentration 10-30%. The isolates J1, T1, K1 and K3 were tolerant to the same temperature range, salinity and pH conditions. J2 and K3 exhibited high tolerance to 30% PEG concentration. Out of 14stress tolerant isolates, we were able to distinguish 5 different banding patterns using PCR amplified ERIC profiling. The high tolerant M3 and V3 were showing different polymorphic banding patterns suggesting that they are different strains. These high tolerant strains can be used for cross inoculation with commercially important legume crops to improve their yield under harsh environmental conditions and for bio fertilizer production.

description: To determine the topological quantum numbers of fractional quantum Hall (FQH) states hosting counter-propagating (CP) downstream ($N_d$) and upstream ($N_u$) edge modes, it is pivotal to study quantized transport both in the presence and absence of edge mode equilibration. While reaching the non-equilibrated regime is challenging for charge transport, we target here the thermal Hall conductance $G_{Q}$, which is purely governed by edge quantum numbers $N_d$ and $N_u$. Our experimental setup is realized with a hBN encapsulated graphite gated monolayer graphene device. For temperatures up to $35mK$, our measured $G_{Q}$ at $ν= $ 2/3 and 3/5 (with CP modes) match the quantized values of non-equilibrated regime $(N_d + N_u)κ_{0}T$, where $κ_{0}T$ is a quanta of $G_{Q}$. With increasing temperature, $G_{Q}$ decreases and eventually takes the value of equilibrated regime $|N_d - N_u|κ_{0}T$. By contrast, at $ν= $1/3 and 2/5 (without CP modes), $G_Q$ remains robustly quantized at $N_dκ_{0}T$ independent of the temperature. Thus, measuring the quantized values of $G_{Q}$ at two regimes, we determine the edge quantum numbers, which opens a new route for finding the topological order of exotic non-Abelian FQH states.
Autocorrelation exponent of conserved spin systems in the scaling regime following a critical quench

description: We study the autocorrelation function of a conserved spin system following a quench at the critical temperature. Defining the correlation length L(t)\sim t^{1/z}, we find that for times t' and t satisfying L(t') << L(t) << L(t')^ϕwell inside the scaling regime, the spin autocorrelation function behaves like = L(t')^{-(d-2+η)} [L(t')/L(t)]^{λ_c}. For the O(n) model in the n -> \infty limit, we show that λ_c=d+2 and ϕ=z/2. We give a heuristic argument suggesting that this result is in fact valid for any dimension d and spin vector dimension n. We present numerical simulations for the conserved Ising model in d=1 and d=2, which are fully consistent with the present theory.

description: To consider how the use of SAR in forest and environmental monitoring is likely to change in the future, it is useful to reflect on how SAR is currently used\r\nacross a range of applications. As documented in the preceding chapters, earlier research has transitioned to applications ranging from the use of SAR for\r\ntracking deforestation to its use in estimating forest height and biomass. The applications landscape is expected to change due to the growing public availability\r\nof SAR data to feed applications, with important missions like the NISAR (NASA-ISRO Synthetic Aperture Radar) and the European Space Agency\u2019s\r\n(ESA\u2019s) Biomass mission planned for launch within a five-year horizon from the publication of this handbook. Limitations notwithstanding, other factors\r\nexpected to further accelerate the application of SAR data include the growing availability of desktop and online platforms with which to process and analyze\r\nradar data, and\u2014as evidenced by this handbook\u2014a growing set of resources to build the user community\u2019s capacity to apply SAR data. In support of\r\nGlobal Forest Observation Initiative (GFOI) and SilvaCarbon, the global network of hubs of the SERVIR program are also poised as important resource centers\r\nto help strengthen capacities within their respective regions to apply SAR for forest monitoring, as well as in other environmental monitoring contexts.

description: The multiplicity properties of massive stars are one of the important outstanding issues in stellar evolution. Quantifying the binary statistics of all evolutionary phases is essential to paint a complete picture of how and when massive stars interact with their companions, and to determine the consequences of these interactions. We investigate the multiplicity of an almost complete census of red supergiant stars (RSGs) in NGC 330, a young massive cluster in the SMC. Using a combination of multi-epoch HARPS and MUSE spectroscopy, we estimate radial velocities and assess the kinematic and multiplicity properties of 15 RSGs in NGC 330. Radial velocities are estimated to better than +/-100 m/s for the HARPS data. The line-of-sight velocity dispersion for the cluster is estimated as 3.20 +0.69-0.52 km/s. When virial equilibrium is assumed, the dynamical mass of the cluster is log (M{dyn} /M{sun}) = 5.20+/-0.17, in good agreement with previous upper limits. We detect significant radial velocity variability in our multi-epoch observations and distinguish between variations caused by atmospheric activity and those caused by binarity. The binary fraction of NGC 330 RSGs is estimated by comparisons with simulated observations of systems with a range of input binary fractions. In this way, we account for observational biases and estimate the intrinsic binary fraction for RSGs in NGC 330 as f{RSG} = 0.3+/-0.1 for orbital periods in the range 2.3< log P [days] <4.3, with q>0.1. Using the distribution of the luminosities of the RSG population, we estimate the age of NGC 330 to be 45+/-5 Myr and estimate a red straggler fraction of 50%. We estimate the binary fraction of RSGs in NGC 330 and conclude that it appears to be lower than that of main-sequence massive stars, which is expected because interactions between an RSG and a companion are assumed to effectively strip the RSG envelope.

description: $ΔL =2$ lepton number violation (LNV) at the TeV scale could provide an alternative interpretation of positive signal(s) in future neutrinoless double beta $(0νββ)$ decay experiments. An interesting class of models from this point of view are those that at low energies give rise to dimension-9 vector operators and a dimension-7 operator, both of whose $0νββ$-decay rates are "chirally suppressed". We study and compare the sensitivities of $0νββ$-decay experiments and LHC searches to a simplified model in this class of TeV-scale LNV that is also $SU(2)_L \times U(1)_Y$ gauge invariant. The searches for $0νββ$ decay, which are here diluted by a chiral suppression of the vector operators, are found to be less constraining than LHC searches whose reach is increased by the assumed kinematic accessibility of the mediator particles. For the chirally suppressed dimension-7 operator generated by TeV-scale mediators, in contrast, $0νββ$-decay searches place strong constraints on the size of the new Yukawa coupling. Signals of this model at the LHC and $0νββ$-decay experiments are entirely uncorrelated with the observed neutrinos masses, as these new sources of LNV give negligible contributions to the latter. We find the prospects for the high-luminosity LHC and ton-scale $0νββ$-decay experiments to uncover the chirally-suppressed mechanism with TeV-scale LNV to be promising. We also comment on the sensitivity of the $0νββ$-decay lifetime to certain unknown low-energy constants that in the case of dimension-9 {\it scalar} operators are expected to be large due to non-perturbative renormalization.

description: Farming system research (FSR) is presently being promoted as a more appropriate research tool for agricultural development in LDQ's. However, FSR has tended to concentrate on rapid, short-term gains. Data from Northern Thailand are used to demonstrate that increased yields do not necessarily ensure sustainability over time. Agroecosystems analysis combined with FSR can facilitate development of long-term sustainable technologies.

description: Introduction: Radiotherapy is an established treatment option for prostate cancer (PCa), both as primary treatment and secondary treatment after radical prostatectomy (RP). Since 1998, detailed data on radiotherapy delivered to Swedish men with PCa (e.g. treatment modalities, absorbed doses, fractionation) have been collated within PCa data Base Sweden (PCBaSe). This study reports patterns of radical radiotherapy for PCa in Sweden over the past two decades. Materials and methods: All men with non-metastatic PCa (1998–2016) who received external beam radiotherapy (EBRT) or high or low dose-rate brachytherapy (HDR-BT/LDR-BT) were identified in PCBaSe. Analyses included: trends in radiation techniques, fractionation patterns and total doses over time; PCa-specific survival comparing treatment in 2007–2017 with 1998–2006; and regional variation in type of primary radiotherapy. Results: About 20,876 men underwent primary radiotherapy. The main treatment modalities include conventionally fractionated (2.0 Gy/fraction) EBRT (51%), EBRT with HDR-BT boost (27%) and hypofractionated (>2.4 Gy/fraction) EBRT (11%). EBRT with photon or proton boost and HDR-BT and LDR-BT monotherapies were each used minimally. Use of dose-escalated EBRT (>74 Gy) and moderate hypofractionation increased over time, while use of HDR-BT declined. Considerable regional variation in treatment modalities was apparent. Risk of PCa death following primary radiotherapy had declined for intermediate-risk (HR: 0.60; 95%CI 0.47–0.87) and high-risk PCa (HR: 0.72; 95%CI 0.61-0.86). Discussion: Increased use of dose escalation and hypofractionated EBRT has occurred in Sweden over the past two decades, reflecting current evidence and practice guidelines. Disease-specific outcomes have also improved. Data collected in PCBaSe provide an excellent resource for further research into RT use in PCa management.
Confronting the IR Fixed Point Cosmology with High Redshift Observations

description: We use high-redshift type Ia supernova and compact radio source data in order to test the infrared (IR) fixed point model of the late Universe which was proposed recently. It describes a cosmology with a time dependent cosmological constant and Newton constant whose dynamics arises from an underlying renormalization group flow near an IR-attractive fixed point. Without any finetuning or quintessence field it yields $Ω_{\rm M}=Ω_Λ=1/2$. Its characteristic $t^{4/3}$-dependence of the scale factor leads to a distance-redshift relation whose predictions are compared both to the supernova and to the radio source data. According to the $χ^2$ test, the fixed point model reproduces the data at least as well as the best-fit (Friedmann-Robertson-Walker) standard cosmology.Furthermore, we extend the original fixed point model by assuming that the fixed point epoch is preceded by an era with constant $G$ and $Λ$. By means of a Monte Carlo simulation we show that the data expected from the forthcoming SNAP satellite mission could detect the transition to the fixed point regime provided it took place at a redshift of less than about 0.5.

title: Radar Remote Sensing of Mangrove Forests
Creators: name: Simard, Marc
Publisher: name: NASA
Year: 2019

description: Mangrove forests are highly productive ecosystems providing critical ecosystem services. It is estimated that about a third of mangrove forests have been lost\r\nduring the last century and are still being decimated at a rate of about 0.4% per year. Mangrove forests are thin strips of forests living along tropical coasts.\r\nThese environments are generally cloudy; optical remote sensing instruments provide limited temporal coverage to ensure consistent monitoring of mangrove\r\nhealth and status. Radar remote sensing enables all-weather monitoring of mangrove forest gain and loss in extent. In addition, it can observe several\r\nparameters related to vertical canopy structure and biomass. The first part of this chapter introduces mangrove forests and the state-of-the-art radar remote\r\nsensing techniques to measure and monitor mangrove forest structure. The second part of this chapter presents a step-by-step tutorial on the use of radar\r\nremote sensing to make these measurements. After this chapter, the reader will be able to perform analysis of radar images of mangrove forests and more.
Physical Violations of the Bulk-Edge Correspondence in Topological Electromagnetics

description: In this Letter, we discuss two general classes of apparent violations of the bulk-edge correspondence principle for uniform topological photonic materials, associated with the asymptotic behavior of the surface modes for diverging wavenumbers. Considering a nonreciprocal plasma as a model system, we show that the inclusion of spatial dispersion (e.g., hydrodynamic nonlocality) formally restores the bulk-edge correspondence by avoiding an unphysical response at large wavenumbers. Most importantly, however, our findings show that, for the considered cases, the correspondence principle is physically violated for all practical purposes, as a result of the unavoidable attenuation of highly confined modes even if all materials are assumed perfect, with zero intrinsic bulk losses, due to confinement-induced Landau damping or nonlocality-induced radiation leakage. Our work helps clarifying the subtle and rich topological wave physics of continuous media.

description: Prices for milk and dairy products have become increasingly unstable as the Government support safety net has been lowered. Dairy cooperatives’ traditional pricing system is delineated and their role in the new market environment is discussed. Some of the risks involved in using emerging hedging mechanisms such as futures, options, and forward contracting for managing price risks are assessed. The traditional pricing system in regard to managing price risks is evaluated. Guidelines for developing a cooperative’s hedging strategy are suggested.

description: The reduction in Government storage payments had a great effect on cooperative elevator structure and operations during the late 1980s and early 1990s. Other Government programs such as payment-in-kind (PIK), grain sales (Commodity Credit Corporation (CCC) catalog and auction sales), and the Conservation Reserve Pprogram (CRP) also affected cooperative elevators in terms of excess storage capacity and other factors. In 1988 and 1992, managers of 71 cooperatives in 7 States were surveyed about their structure and operations. This report discusses the effect of Government program changes and other factors between 1988 and 1992 on the structure and operations of the surveyed cooperatives.

description: Agricultural producers establish and support a cooperative when it provides benefits they would not obtain by individual actions. Cooperatives are distinguished from other types of organized ventures in that owners are the primary users of services, who benefit in proportion to use. Members of a cooperative typically have diverse economic interests. These may encompass size, type and location of farm enterprises, and length of membership. Maintaining cohesiveness for building incentives to cooperate is becoming more complex as more variations in production practices and technology become available, new forms of business relationships are developed, and as consumer preferences continue to become more diverse and demanding. The objectives of this research are: first, examine the role of member consensus and policy consistency in a cooperative; second, examine member consensus and policy in a strategic framework of competition, where competitors offer individualized terms to selective producers that are difficult for cooperatives to match; and third, develop a game theory analysis for situations where cooperatives need to attract large-scale producers.

description: Let $X$ be a right Hilbert module over a $C^*$-algebra $A$ equipped with the canonical operator space structure. We define an elementary operator on $X$ as a map $ϕ: X \to X$ for which there exists a finite number of elements $u_i$ in the $C^*$-algebra $\mathbb{B}(X)$ of adjointable operators on $X$ and $v_i$ in the multiplier algebra $M(A)$ of $A$ such that $ϕ(x)=\sum_i u_i xv_i$ for $x \in X$. If $X=A$ this notion agrees with the standard notion of an elementary operator on $A$. In this paper we extend Mathieu's theorem for elementary operators on prime $C^*$-algebras by showing that the completely bounded norm of each elementary operator on a non-zero Hilbert $A$-module $X$ agrees with the Haagerup norm of its corresponding tensor in $\mathbb{B}(X)\otimes M(A)$ if and only if $A$ is a prime $C^*$-algebra.
