description: The method of solar magnetic field calibration for the filter-based magnetograph is normally the linear calibration method under weak-field approximation that cannot generate the strong magnetic field region well due to the magnetic saturation effect. We try to provide a new method to carry out the nonlinear magnetic calibration with the help of neural networks to obtain more accurate magnetic fields. We employed the data from Hinode/SP to construct a training, validation and test dataset. The narrow-band Stokes I, Q, U, and V maps at one wavelength point were selected from all the 112 wavelength points observed by SP so as to simulate the single-wavelength observations of the filter-based magnetograph. We used the residual network to model the nonlinear relationship between the Stokes maps and the vector magnetic fields. After an extensive performance analysis, it is found that the trained models could infer the longitudinal magnetic flux density, the transverse magnetic flux density, and the azimuth angle from the narrow-band Stokes maps with a precision comparable to the inversion results using 112 wavelength points. Moreover, the maps that were produced are much cleaner than the inversion results. The method can effectively overcome the magnetic saturation effect and infer the strong magnetic region much better than the linear calibration method. The residual errors of test samples to standard data are mostly about 50 G for both the longitudinal and transverse magnetic flux density. The values are about 100 G with our previous method of multilayer perceptron, indicating that the new method is more accurate in magnetic calibration.

description: We discuss the Attractor Equations of N=2, $d=4$ supergravity in an extremal black hole background with arbitrary electric and magnetic fluxes (charges) for field-strength two-forms. The effective one-dimensional Lagrangian in the radial (evolution) variable exhibits features of a spontaneously broken supergravity theory. Indeed, non-BPS Attractor solutions correspond to the vanishing determinant of a (fermionic) gaugino mass matrix. The stability of these solutions is controlled by the data of the underlying Special Kähler Geometry of the vector multiplets' moduli space. Finally, after analyzing the 1-modulus case more in detail, we briefly comment on the choice of the Kähler gauge and its relevance for the recently discussed entropic functional.

'Really respectable settlers' : Peninsular War veterans in the Australian colonies, 1820s and 1830s

description: As the Napoleonic Wars convulsed Europe during the early nineteenth century, many more British young men than ever before became army officers, particularly during the latter part of the conflict, fought in Spain and Portugal between 1808 and 1814. The Peninsular War provided not only employment, but also the opportunity to climb the social ladder. As this thesis will demonstrate, the majority of British army commissions in this period were not purchased, and it was these men who later came to settle in the Australian colonies. After the demobilization of the British army following the battle of Waterloo in 1815, many officers found themselves on half-pay, doing the rounds of government offices seeking colonial positions; some were successful and were appointed to New South Wales. As well, many of those who came to New South Wales in garrison regiments, from 1817 onwards, found the place appealing and decided to settle. These British army officers, and those others who came in the next couple of decades, were a unique group of emigrants because of the skills they brought with them acquired in the army: self-discipline, self-reliance, the knowledge of how to discipline men, reconnaissance and exploring techniques, mapping, survey, engineering, town planning, medical skills and the building of roads and bridges. They were also Protestant, educated, literate and artistic men, and the carriers of British colonizing notions. They arrived at an opportune time to fill key positions in the newly created civil services in New South Wales and Van Diemen's Land. They also took advantage of British government regulations and obtained land grants under favourable conditions, something hitherto unattainable for them in Britain. In any case, it was mutually beneficial for the British Government and the Australian colonies to plant ex-army officers in what was the colony farthest away from Britain. Also revealed are the social networks created by Peninsular War veterans on the other side of the world, and their influence in the Australian colonies. These networks made an impact on the exercise of the law, marriage and settlement patterns, and the social and public life of the colonies. Many of the men who in earlier histories have been called 'the founding fathers' of Australia had a Peninsular War background and developed related social networks. John Macarthur proposed to Commissioner Bigge in1821 that the colony of New South Wales needed 'really respectable settlers'. Peninsular War veterans proved to be ideal in this respect, and in many others besides. The role of these veterans demonstrates key aspects of the emergence of the 'second' British Empire in the early nineteenth century, and also the change in the nature of the colony of New South Wales, from a penal and military society to a free one.

description: A new planet has been recently discovered around Proxima Centauri. With an orbital separation of $\sim$$1.44$ au and a minimum mass of about $7$ $M_{\oplus}$, Proxima c is a prime direct imaging target for atmospheric characterization. The latter can only be performed with a good understanding of the space environment of the planet, as multiple processes can have profound effects on the atmospheric structure and evolution. Here, we take one step in this direction by generating physically-realistic numerical simulations of Proxima's stellar wind, coupled to a magnetosphere and ionosphere model around Proxima c. We evaluate their expected variation due to the magnetic cycle of the host star, as well as for plausible inclination angles for the exoplanet orbit. Our results indicate stellar wind dynamic pressures comparable to present-day Earth, with a slight increase (by a factor of 2) during high activity periods of the star. A relatively weak interplanetary magnetic field at the distance of Proxima c leads to negligible stellar wind Joule heating of the upper atmosphere (about $10\%$ of the solar wind contribution on Earth) for an Earth-like planetary magnetic field ($0.3$ G). Finally, we provide an assessment of the likely extreme conditions experienced by the exoplanet candidate Proxima d, tentatively located at $0.029$ au with a minimum mass of $0.29$ $M_{\oplus}$.

Vortex patches choreography for active scalar equations

Subjects: subject: Analysis of PDEs (math.AP)
subject: FOS: Mathematics

description: This paper deals with the existence of $N$ vortex patches located at the vertex of a regular polygon with $N$ sides that rotate around the center of the polygon at a constant angular velocity. That is done for Euler and (SQG)$_β$ equations, with $β\in(0,1)$, but may be also extended to more general models. The idea is the desingularization of the Thomsom polygon for the $N$ point vortex system, that is, $N$ point vortices located at the vertex of a regular polygon with $N$ sides. The proof is based on the study of the contour dynamics equation combined with the application of the infinite dimensional Implicit Function theorem and the well--chosen of the function spaces.

description: Direct observation of the droplet breakup process in high-speed gas flows is a critical challenge that needs to be addressed to elucidate the physical mechanisms underlying the fragmentation phenomenon. Here, we present a high-magnification and high-speed shadowdograph technique that allows the visualization of this process over its whole evolution and resolves detailed features of the breakup zone. The developed experimental method uses a high-speed camera equipped with a long-distance microscope. The backlight illumination source is provided by the laser-induced fluorescence of a dye solution that delivers short pulses at a high-repetition rate. Artefacts resulting from the laser coherence are therefore reduced.

description: We discuss several well known results about Schur functions that can be proved using cancellations in alternating summations; notably we shall discuss the Pieri and Murnaghan-Nakayama rules, the Jacobi-Trudi identity and its dual (Von N{ä}gelsbach-Kostka) identity, their proofs using the correspondence with lattice paths of Gessel and Viennot, and finally the Littlewood-Richardson rule. Our our goal is to show that the mentioned statements are closely related, and can be proved using variations of the same basic technique. We also want to emphasise the central part that is played by matrices over $\{0,1\}$ and over $\N$; we show that the Littlewood-Richardson rule as generalised by Zelevinsky has elegant formulations using either type of matrix, and that in both cases it can be obtained by two successive reductions from a large signed enumeration of such matrices, where the sign depends only on the row and column sums of the matrix.

description: We studied the hyperlogic HyperQPTL, which combines the concepts of trace relations and $ω$-regularity. We showed that HyperQPTL is very expressive, it can express properties like promptness, bounded waiting for a grant, epistemic properties, and, in particular, any $ω$-regular property. Those properties are not expressible in previously studied hyperlogics like HyperLTL. At the same time, we argued that the expressiveness of HyperQPTL is optimal in a sense that a more expressive logic for $ω$-regular hyperproperties would have an undecidable model checking problem. We furthermore studied the realizability problem of HyperQPTL. We showed that realizability is decidable for HyperQPTL fragments that contain properties like promptness. But still, in contrast to the satisfiability problem, propositional quantification does make the realizability problem of hyperlogics harder. More specifically, the HyperQPTL fragment of formulas with a universal-existential propositional quantifier alternation followed by a single trace quantifier is undecidable in general, even though the projection of the fragment to HyperLTL has a decidable realizability problem. Lastly, we implemented the bounded synthesis problem for HyperQPTL in the prototype tool BoSy. Using BoSy with HyperQPTL specifications, we have been able to synthesize several resource arbiters. The synthesis problem of non-linear-time hyperlogics is still open. For example, it is not yet known how to synthesize systems from specifications given in branching-time hyperlogics like HyperCTL$^*$.

2D Models for Dust-driven AGB Star Winds

Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: New axisymmetric (2D) models for dust-driven winds of C-stars are presented which include hydrodynamics with radiation pressure on dust, equilibrium chemistry and time-dependent dust formation with coupled grey Monte Carlo radiative transfer. Considering the most simple case without stellar pulsation (hydrostatic inner boundary condition) these models reveal a more complex picture of the dust formation and wind acceleration as compared to earlier published spherically symmetric (1D) models. The so-called exterior $κ$-mechanism causes radial oscillations with short phases of active dust formation between longer phases without appreciable dust formation, just like in the 1D models. However, in 2D geometry, the oscillations can be out-of-phase at different places above the stellar atmosphere which result in the formation of dust arcs or smaller caps that only occupy a certain fraction of the total solid angle. These dust structures are accelerated outward by radiation pressure, expanding radially and tangentially like mushroom clouds, while dust-poor matter is falling back towards the star at other places. A highly dynamical and turbulent dust formation zone is created in this way, which again leads to inhomogeneous dust production. Further away from the star, flow instabilities (e.g. Rayleigh-Taylor) have time to fragment the outward moving arcs and shells to produce numerous small-scale cloud-like sub-structures.

description: We present observations of SN 2020faa. This Type II supernova displays a luminous light curve that started to rebrighten from an initial decline. We investigate this in relation to the famous supernova iPTF14hls, which received a lot of attention and multiple interpretations in the literature, however whose nature and source of energy still remains unknown. We demonstrate the great similarity between SN 2020faa and iPTF14hls during the first 6 months, and use this comparison both to forecast the evolution of SN 2020faa and to reflect on the less well observed early evolution of iPTF14hls. We present and analyse our observational data, consisting mainly of optical light curves from the Zwicky Transient Facility in the gri bands as well as a sequence of optical spectra. We construct colour curves, a bolometric light curve, compare ejecta-velocity and Black-body radius evolutions for the two supernovae, as well as for more typical Type II supernovae. The light curves show a great similarity with those of iPTF14hls over the first 6 months, in luminosity, timescale and colours. Also the spectral evolution of SN 2020faa is that of a Type II supernova, although it probes earlier epochs than those available for iPTF14hls. The similar light curve behaviour is suggestive of SN 2020faa being a new iPTF14hls. We present these observations now to advocate follow-up observations, since most of the more striking evolution of supernova iPTF14hls came later, with light curve undulations and a spectacular longevity. On the other hand, for SN 2020faa we have better constraints on the explosion epoch than we had for iPTF14hls, and we have been able to spectroscopically monitor it from earlier phases than was done for the more famous sibling.

description: The study of collective animal behaviour must progress through a comparison between the theoretical predictions of numerical models and data coming from empirical observations. To this aim it is important to develop methods of three-dimensional (3D) analysis that are at the same time informative about the structure of the group and suitable to empirical data. In fact, empirical data are considerably noisier than numerical data, and they are subject to several constraints. We review here the tools of analysis used by the STARFLAG project to characterise the 3D structure of large flocks of starlings in the field. We show how to avoid the most common pitfalls i the quantitative analysis of 3D animal groups, with particular attention to the problem of the bias introduced by the border of the group. By means of practical examples, we demonstrate that neglecting border effects gives rise to artefacts when studying the 3D structure of a group. Moreover, we show that mathematical rigour is essential to distinguish important biological properties from trivial geometric features of animal groups.

description: Background: Widespread and sustained adoption of telemedicine in long-term residential care is emerging. Nursing home (NH) nurses play a key role in collaborating with remote physicians to manage residents' medical conditions through videoconferencing. Therefore, understanding of interprofessional collaboration and effective communication between nurses and physicians is critical to ensure quality of care and safety during teleconsultations. Aims: To explore NH nurses' and physicians' experiences of interprofessional collaboration and communication during teleconsultations. Methods: A qualitative descriptive design was adopted. Purposive sampling was conducted to recruit 22 physicians and nurses involved in NH teleconsultations. Semi-structured online interviews were conducted, and data were thematically analyzed. Results: Three themes were identified: (1) Manner of communication in telemedicine, (2) sociocultural influences in collaborative practice, and (3) role expectations in telemedicine. Both nurses and physicians recognized the importance of building and maintaining trust as physicians heavily depended on nurses for provision of objective information for clinical decision-making. However, practice differences were observed between nurses and physicians during teleconsultations. Sociocultural influences such as power relations and language barriers also affected the nurse–physician relationship and interpersonal communication. Additionally, different performance expectations were identified between nurses and physicians. Conclusion: Interprofessional collaboration in teleconsultations is challenging because of lack of in-person assessment and dependence on nurses for clinical information. In addition, expectations and communication styles differ among healthcare professionals. This study called for interprofessional telemedicine training with incorporation of shared mental models to improve role clarity and communication. Given the international-dominated healthcare workforce in long-term care, the development of cultural competency could also be considered in telemedicine training to enhance nurse–physician collaborative practice. Clinical Relevance: Telemedicine is increasingly adopted in long-term care settings, where multidisciplinary healthcare professionals from different health institutions are involved in resident care. Interprofessional collaboration should be incorporated into telehealth education for enhanced clinical practice in this care delivery model.
Femtosecond currents in transition metal dichalcogenides monolayers

description: We theoretically study the interaction of an ultrafast intense linearly polarized optical pulse with monolayers of transition metal dichalcogenides (TMDCs). Such a strong pulse redistributes electrons between the bands and generates femtosecond currents during the pulse. Due to the large bandwidth of the incident pulse, this process is completely off-resonant. While in TMDCs the time-reversal symmetry is conserved, the inversion symmetry is broken and these monolayers have the axial symmetry along armchair direction but not along the zigzag one. Therefore, the pulse polarized along the asymmetric direction of TMDC monolayer generates both longitudinal, i.e., along the direction of polarization, and transverse, i.e., in the perpendicular direction, currents. Such currents result in charge transfer through the system. We study different TMDC materials and show how the femtosecond transport in TMDC monolayers depend on their parameters, such as lattice constant and bandgap.
Multi-level, multi-party singlets as ground states and their role in entanglement distribution

Year: 2006

description: We show that a singlet of many multi-level quantum systems arises naturally as the ground state of a physically-motivated Hamiltonian. The Hamiltonian simply exchanges the states of nearest-neighbours in some network of qudits (d-level systems); the results are independent of the strength of the couplings or the network's topology. We show that local measurements on some of these qudits project the unmeasured qudits onto a smaller singlet, regardless of the choice of measurement basis at each measurement. It follows that the entanglement is highly persistent, and that through local measurements, a large amount of entanglement may be established between spatially-separated parties for subsequent use in distributed quantum computation.

description: Given the multitude of growth habits, pronounced sensitivity to ambient conditions and wide range of scales involved, snowflake crystals are one of the most challenging systems to model. The present work focuses on the development and validation of a coupled flow/species/phase solver based on the lattice Boltzmann method. It is first shown that the model is able to correctly capture species and phase growth coupling. Furthermore, through a study of crystal growth subject to ventilation effects, it is shown that the model correctly captures hydrodynamics-induced asymmetrical growth. The validated solver is then used to model snowflake growth under different ambient conditions with respect to humidity and temperature in the plate-growth regime section of the Nakaya diagram. The resulting crystal habits are compared to both numerical and experimental reference data available in the literature. The overall agreement with experimental data shows that the proposed algorithm correctly captures both the crystal shape and the onset of primary and secondary branching instabilities. As a final part of the study the effects of forced convection on snowflake growth are studied. It is shown, in agreement with observations in the literature, that under such condition the crystal exhibits non-symmetrical growth. The non-uniform humidity around the crystal due to forced convection can even result in the coexistence of different growth modes on different sides of the same crystal.

description: Massive stars played a key role in the early evolution of the Universe. They formed with the first halos and started the re-ionisation. It is therefore very important to understand their evolution. In this review, we first recall the effect of metallicity (Z) on the evolution of massive stars. We then describe the strong impact of rotation induced mixing and mass loss at very low Z. The strong mixing leads to a significant production of primary nitrogen 14, carbon 13 and neon 22. Mass loss during the red supergiant stage allows the production of Wolf-Rayet stars, type Ib,c supernovae and possibly gamma-ray bursts (GRBs) down to almost Z=0 for stars more massive than 60 solar masses. Galactic chemical evolution models calculated with models of rotating stars better reproduce the early evolution of N/O, C/O and C12/C13. Finally, the impact of magnetic fields is discussed in the context of GRBs.

description: Poultry manure application in excess of red raspberry (Rubus idaeus L.) nitrogen (N) requirement has been suggested as a significant contributor to elevated groundwater nitrate concentrations in the Abbotsford Aquifer. The purpose of this study was to examine the effect of poultry layer manure application on N processes in raspberry fields. An experiment was conducted at a site with no history of manure application in 1992 (C92) and 1993 (C93) and a site with a history of manure application in 1992 (H92) to determine the influence of rate of poultry layer manure application on the temporal and spatial variation in soil moisture, ammonium and nitrate concentrations, and on N uptake in raspberries. A comparison of soil inorganic N content over the growing season showed that inorganic fertilizer applied at a rate of 55 kg N ha⁻¹ had similar crop N availability as poultry layer manure applied at a rate of 100 kg N ha⁻¹, although small differences were observed at C93. Using manure as the sole source of N resulted in no adverse impact on estimated berry yield, primocane vigour, and crop N uptake, as compared to the inorganic fertilizer treatment. Greater depletion of soil inorganic N was measured near the crop row suggesting that manure and/or fertilizer should be placed there. Raspberry N uptake by the above-ground portion of the crop was relatively low (90-100 kg N ha⁻¹), averaged across treatments, while N removal from the field was only in the form of berries (up to 20 kg N ha⁻¹) since raspberry canes remain in the field where the plant N is recycled. Soil nitrate in August in the control treatment at H92 was 51 and 83% higher than that at C92 and C93, respectively. A second experiment conducted at C92 and C93 found that manure N recovery as soil inorganic N was approximately 50% within 30 days of manure application in late February to early March. Mineralization and nitrification of manure N was rapid at C93 despite the fact that soil temperatures were 4°C cooler than at C92. Additional experiments showed that the above-ground portion of a spring oats (Avena sativa L.) cover crop can be as high as 100 kg N ha⁻¹ when seeded by early August with no adverse effect on primocanes, however when seeded two weeks later N uptake was only half that amount.

description: e formulate a method for studying the quantum field dynamics of ultracold Bose gases confined within optical lattice potentials, within the lowest Bloch-band Bose-Hubbard model. Our formalism extends the two-sites results of Phys. Rev. Lett. {\bf86}, 000568 (2001) to the general case of $M$ lattice sites. The methodology is based on mapping the Bose-Hubbard Hamiltonian to an $SU(M)$ pseudospin problem and truncating the resulting hierarchy of dynamical equations for correlation functions, up to pair-correlations between $SU(M)$ generators. Agreement with few-site exact many-particle calculations is consistently better than the corresponding Hartree-Fock-Bogoliubov approximation. Moreover, our approximation compares favorably with a more elaborate two-particle irreducible effective action formalism, at a fraction of the analytic and numerical effort.

description: A central feature of an emerging infectious disease in a pandemic scenario is the spread through geographical scales and the impacts on different locations according to the adopted mitigation protocols. We investigated a stochastic epidemic model with the metapopulation approach in which patches represent municipalities. Contagion follows a stochastic compartmental model for municipalities; the latter, in turn, interact with each other through recurrent mobility. As a case of study, we consider the epidemic of COVID-19 in Brazil performing data-driven simulations. Properties of the simulated epidemic curves have very broad distributions across different geographical locations and scales, from states, passing through intermediate and immediate regions down to municipality levels. Correlations between delay of the epidemic outbreak and distance from the respective capital cities were predicted to be strong in several states and weak in others, signaling influences of multiple epidemic foci propagating towards the inland cities. Responses of different regions to a same mitigation protocol can vary enormously implying that the policies of combating the epidemics must be engineered according to the region' specificity but integrated with the overall situation. Real series of reported cases confirm the qualitative scenarios predicted in simulations. Even though we restricted our study to Brazil, the prospects and model can be extended to other geographical organizations with heterogeneous demographic distributions.

description: We begin a systematic study of Quantum Energy Inequalities (QEIs) in relation to local covariance. We define notions of locally covariant QEIs of both 'absolute' and 'difference' types and show that existing QEIs satisfy these conditions. Local covariance permits us to place constraints on the renormalised stress-energy tensor in one spacetime using QEIs derived in another, in subregions where the two spacetimes are isometric. This is of particular utility where one of the two spacetimes exhibits a high degree of symmetry and the QEIs are available in simple closed form. Various general applications are presented, including a priori constraints (depending only on geometric quantities) on the ground-state energy density in a static spacetime containing locally Minkowskian regions. In addition, we present a number of concrete calculations in both two and four dimensions which demonstrate the consistency of our bounds with various known ground- and thermal state energy densities. Examples considered include the Rindler and Misner spacetimes, and spacetimes with toroidal spatial sections. In this paper we confine the discussion to globally hyperbolic spacetimes; subsequent papers will also discuss spacetimes with boundary and other related issues.

description: The near-term search for life beyond the solar system currently focuses on transiting planets orbiting small M dwarfs, and the challenges of detecting signs of life in their atmospheres. However, planets orbiting white dwarfs (WDs) would provide a unique opportunity to characterize rocky worlds. The discovery of the first transiting giant planet orbiting a white dwarf, WD 1856+534b, showed that planetary-mass objects can survive close-in orbits around WDs. The large radius ratio between WD planets and their host renders them exceptional targets for transmission spectroscopy. Here, we explore the molecular detectability and atmospheric characterization potential for a notional Earth-like planet, evolving in the habitable zone of WD 1856+534, with the James Webb Space Telescope (JWST). We establish that the atmospheric composition of such Earth-like planets orbiting WDs can be precisely retrieved with JWST. We demonstrate that robust > 5$σ$ detections of H$_2$O and CO$_2$ can be achieved in a 5 transit reconnaissance program, while the biosignatures O$_3$ + CH$_4$, and O$_3$ + N$_2$O can be detected to > 4$σ$ in as few as 25 transits. N$_2$ and O$_2$ can be detected to > 5$σ$ within 100 transits. Given the short transit duration of WD habitable zone planets (~ 2 minutes for WD 1856+534), conclusive molecular detections can be achieved in a small or medium JWST transmission spectroscopy program. Rocky planets in the WD habitable zone therefore represent a promising opportunity to characterize terrestrial planet atmospheres and explore the possibility of a second genesis on these worlds.

description: The role of local higher-twist ($τ> 3$) spin-1/2 fermionic operators of the strongly coupled ${\cal {N}}=4$ supersymmetric Yang-Mills theory on the symmetric and antisymmetric deep inelastic scattering (DIS) structure functions is investigated. The calculations are carried out in terms of the duality between ${\cal {N}}=4$ SYM theory and type IIB supergravity on AdS$_5 \times S^5$. Particularly, we explicitly obtain the structure functions for single-trace spin-1/2 fermionic operators in the 20$^*$ and 60$^*$ irreducible representations of $SU(4)_R$, corresponding to twists 4 and 5, respectively. We also calculate the contributions of other single-trace spin-1/2 fermionic operators in the 4, 20 and 60 irreducible representations of $SU(4)_R$. New important effects are found in comparison with the minimal twist ($τ= 3$) case, and they are studied thoroughly.

description: Under the CGIAR Initiative on National Policies and Strategies (NPS), International Water Management Institute (IWMI) and Council for Energy, Environment, and Water (CEEW) jointly organized a National Stakeholder Workshop on “Policy Coherence for Food, Land, and Water” in India on 16th June 2023 at India Habitat Center in New Delhi. Guided by NITI Aayog, an apex public policy think tank of the Government of India, IWMI and CEEW researched the policy landscape at the national level in the food, land, and water (FLW) sectors, shortlisting seven central government schemes to understand ways to strengthen policy coherence and impact. The workshop was attended by representatives from the Ministry of Jal Shakti, the Ministry of Agriculture and Farmers’ Welfare, NITI Aayog and 17 government and civil society organizations working in the food, land, and water sectors. Under the able guidance of Debashree Mukherjee (Special Secretary, Ministry of Jal Shakti) and Avinash Mishra (Advisor, NITI Aayog), the participants discussed the study’s key recommendations, existing institutional mechanisms to catalyze coherence, harnessing synergies, and balancing trade-offs across the food, land, and water sectors.
