description: During the visual observations of optical imaging data obtained from the DECaLS, a serendipitous discovery emerged, revealing the presence of a ringed galaxy, DES J024008.08-551047.5 (DJ0240). We performed one dimensional isophotal and two-dimensional GALFIT analysis to confirm the orthogonal nature of the ring galaxy and identify distinct components within the host galaxy. We discovered the galaxy DJ0240 as a potential PRG candidate with a ring component positioned almost perpendicular to the host galaxy. The position angles of the ring and host components have been determined to be 80 and 10 degrees, respectively, indicating that they are nearly orthogonal to each other. We observed that the ring component extends three times more than the host galaxy and shows a distinct colour separation, being bluer than the host. The estimated g - r colour values of host and ring components are 0.86+/-0.02 and 0.59+/-0.10 mag, respectively. The colour value of the ring component is similar to typical spiral galaxies. The host galaxy`s colour and the presence of a bulge and disk components indicate the possibility of the host galaxy being a lenticular type. Based on the comparison of photometric properties between the PRGs and other ring-type galaxies (RTGs), our findings reveal a subtle, yet noticeable, colour difference between the host and ring components. We observed that both host and ring components of DJ0240 align more closely with PRGs than with RTGs. Furthermore, we compared the sersic index values of the ring component (nring) of galaxy DJ0240 with a selected sample of PRGs and Hoag-type galaxies. The results showed DJ0240 had a remarkably low nring value of 0.13, supporting the galaxy`s classification as a PRG. Hence, we suggest that the ring galaxy DJ0240 is a highly promising candidate for inclusion in the family of PRGs.

description: The simplest extension of the supersymmetric standard model - the addition of one singlet superfield - can have a profound impact on the Higgs and its decays. We perform a general operator analysis of this scenario, focusing on the phenomenologically distinct scenarios that can arise, and not restricting the scope to the narrow framework of the NMSSM. We reexamine decays to four b quarks and four tau's, finding that they are still generally viable, but at the edge of LEP limits. We find a broad set of Higgs decay modes, some new, including those with four gluon final states, as well as more general six and eight parton final states. We find the phenomenology of these scenarios is dramatically impacted by operators typically ignored, specifically those arising from D-terms in the hidden sector, and those arising from weak-scale colored fields. In addition to sensitivity of m_Z, there are potential tunings of other aspects of the spectrum. In spite of this, these models can be very natural, with light stops and a Higgs as light as 82 GeV. These scenarios motivate further analyses of LEP data as well as studies of the detection capabilities of future colliders to the new decay channels presented.

description: Using urban household-level survey data from 1992 to 1998, we provide estimates of final demand for edible vegetable oils and animal fats in three regions of China based on the LinQuad incomplete demand system. For each region, the demand for the major "staple" oil is price inelastic. The demand for "condiment" or flavoring oils is more price responsive. All edible oils and fats have positive income elasticity, but smaller than one. Using the LinQuad parameter estimates, we provide exact measures of urban consumer welfare losses associated with trade restrictions on vegetable oil imports. Consumers suffer a significant welfare loss of the order of $ 392 million (1998 dollars).

description: We investigate the dynamics of the driven Jaynes-Cummings model, where a two-level atom interacts with a quantized field and both, atom and field, are driven by an external classical field. Via an invariant approach, we are able to transform the corresponding Hamiltonian into the one of the standard Jaynes-Cummings model. Subsequently, the exact analytical solution of the Schrödinger equation for the driven system is obtained and employed to analyze some of its dynamical variables.

description: The derivation of the exact and unique nilpotent Becchi-Rouet-Stora-Tyutin (BRST)- and anti-BRST symmetries for the matter fields, present in any arbitrary interacting gauge theory, has been a long-standing problem in the framework of superfield approach to BRST formalism. These nilpotent symmetry transformations are deduced for the four (3 + 1)-dimensional (4D) complex scalar fields, coupled to the U(1) gauge field, in the framework of augmented superfield formalism. This interacting gauge theory (i.e. QED) is considered on a six (4, 2)-dimensional supermanifold parametrized by four even spacetime coordinates and a couple of odd elements of the Grassmann algebra. In addition to the horizontality condition (that is responsible for the derivation of the exact nilpotent symmetries for the gauge field and the (anti-)ghost fields), a new restriction on the supermanifold, owing its origin to the (super) covariant derivatives, has been invoked for the derivation of the exact nilpotent symmetry transformations for the matter fields. The geometrical interpretations for all the above nilpotent symmetries are discussed, too.

description: Bright galaxies at sub-millimetre wavelengths from Herschel are now well known to be predominantly strongly gravitationally lensed. The same models that successfully predicted this strongly lensed population also predict about one percent of faint $450μ$m-selected galaxies from deep James Clerk Maxwell Telescope (JCMT) surveys will also be strongly lensed. Follow-up ALMA campaigns have so far found one potential lens candidate, but without clear compelling evidence e.g. from lensing arcs. Here we report the discovery of a compelling gravitational lens system confirming the lensing population predictions, with a $z_{s} = 3.4 {\pm} 0.4$ submm source lensed by a $z_{spec} = 0.360$ foreground galaxy within the COSMOS field, identified through public JWST imaging of a $450μ$m source in the SCUBA-2 Ultra Deep Imaging EAO Survey (STUDIES) catalogue. These systems will typically be well within the detectable range of future wide-field surveys such as Euclid and Roman, and since sub-millimetre galaxies are predominantly very red at optical/near-infrared wavelengths, they will tend to appear in near-infrared channels only. Extrapolating to the Euclid-Wide survey, we predict tens of thousands of strongly lensed near-infrared galaxies. This will be transformative for the study of dusty star-forming galaxies at cosmic noon, but will be a contaminant population in searches for strongly lensed ultra-high-redshift galaxies in Euclid and Roman.

The nitrogen nutrition of lodgepole pine (Pinus contorta var. contorta) and Sitka spruce (Picea sitchensis (Bong.) Carr.) on a cedar-hemlock cutover on northern Vancouver Island
Creators: name: Bothwell, Karen Sheila
Publisher: name: University of British Columbia
Year: 2009

description: Nursing mixtures with pine or larch have been widely used in Britain and Ireland to aid the establishment of Sitka spruce (Picea sitchensis (Bong.) Carr.) on low-nitrogen, Calluna dominated heathlands and peatlands. The overall result is increased height and diameter growth and increased foliar N concentrations of the spruce and increased N mineralization rates in the forest floor in mixed stands, about 8-10 years after planting. Cedar-hemlock cutovers are ecologically analogous to Calluna sites, both being dominated by ericaceous shrubs and having extremely low nitrogen availability. Growth check symptoms, including reduced leader growth and chlorosis after 5 to 8 years are akin to symptoms observed in British and Irish plantations. A nurse trial was established on a cedar-hemlock cutover on northern Vancouver Island with the objective of testing the efficacy of lodgepole pine (Pinus contorta Dougl. var. contorta) and western white pine (Pinus monticola Dougl. ex D. Don) as nurse species for Sitka spruce regeneration. There were three treatments (pure spruce, spruce in mixture with lodgepole pine and spruce in mixture with white pine), replicated three times. The treatments were established at three different spacings. The trial was remeasured at ten years, however there was no evidence of increased height or diameter growth or increased foliar nitrogen concentrations of the spruce in mixture. Possible reasons for this are suggested. What was evident was the superior growth and nutrition of lodgepole pine on this nitrogen-poor site. The second part of the research focused on examining possible mechanisms leading to the superior growth of lodgepole pine on sites with low nitrogen availability. A field biomass harvest of pine and spruce trees from a cedar-hemlock cutover and a greenhouse bioassay were conducted to examine whether pine accessed more nitrogen, distributed more biomass and nitrogen above ground, and/or was more efficient in the use of the nitrogen taken up through greater production of biomass per unit of nitrogen taken up and/or through greater nitrogen retranslocation at time of senescence. Rooting distribution patterns were examined to determine if pine might have access to different nitrogen pools. Some mycorrhizae, including some species specific to pine, have access to organic forms of nitrogen, therefore mycorrhizal assessments of the communities infecting the pine and spruce were conducted. The abilities of pine and spruce to access different nitrogen sources, both inorganic and organic were also tested. Lodgepole pine took up more nitrogen and had much larger aboveground biomass production. The greater growth and nitrogen status of pine were attributed to greater foliage efficiency. Pine had a deeper root system and the root tips were heavily infected with mycorrhizal fungi, which have high proteolytic activity such as Suillus.

description: In this paper, relationships between U.S. and Canadian wheat prices are examined using cointegration and error correction approach. The use of an error correction model is appropriate because U.S. and Canadian wheat prices are first differenced stationary and cointegrated. The results suggest that both U.S. durum and hard spring wheat prices respond to restore the equilibrium relationship with the corresponding Canadian price while the Canadian price does not respond to restore equilibria. That is, the structure of the respective policies is such that Canadian markets are largely insulated from influences flowing from the United States while U.S. markets are not insulated from Canadian influences. These results could be interpreted to support the contention of U.S. producers that Canadian production subsidies and implicit export subsides have undermined the U.S. price support program. These results also support the price leadership role for Canada in both the durum and hard spring wheat market.

description: We present an estimate of the behaviour of the shear and bulk viscosity coefficients when the QCD critical point is approached from the hadronic side, describing hadronic matter within the statistical bootstrap model (SBM) of strong interactions. The boostrap model shows critical behavior near the quark-hadron transition temperature if the parameter characterizing the degeneracy of Hagedorn states is properly chosen. We calculate the critical exponents and amplitudes of relevant thermodynamic quantities near the QCD critical point and combine them with an Ansatz for the shear and bulk viscosity coefficients to derive the behavior of these coefficients near the critical point. The shear viscosity to entropy density ratio is found to decrease when the temperature is increased, and to approach the Kovtun-Son-Starinets bound 1/(4π) faster near the critical point, while the bulk viscosity coefficient is found to rise very rapidly.

description: Neutron stars are discussed as laboratories of physics of strong gravitational fields. The mass of a neutron star is split into matter energy and gravitational field energy contributions. The energy of the gravitational field of neutron stars is calculated with three different approaches which give the same result. It is found that up to one half of the gravitational mass of maximum mass neutron stars is comprised by the gravitational field energy. Results are shown for a number of realistic equations of state of neutron star matter.

Dissecting the emission from LHAASO J0341+5258: implications for future multi-wavelength observations

description: The Large High Altitude Air Shower Observatory (LHAASO) has detected multiple ultra-high energy (UHE; E$_γ\ge$ 100 TeV) gamma-ray sources in the Milky Way Galaxy, which are associated with Galactic ``PeVatrons'' that accelerate particles up to PeV (= 10$^{15}$ eV) energies. Although supernova remnants (SNRs) and pulsar wind nebulae (PWNe), as source classes, are considered the leading candidates, further theoretical and observational efforts are needed to find conclusive proof to confirm the nature of these PeVatrons. This work aims to provide a phenomenological model to account for the emission observed from the direction of LHAASO J0341+5258, an unidentified UHE gamma-ray source observed by LHAASO. 15 years of Fermi-LAT data was analyzed to find the high energy (HE; 100 MeV $\le$ E$_γ$ $\le$ 100 GeV) GeV gamma-ray counterpart of LHAASO J0341+5258, in the 4FGL-DR3 catalog. We have explained the spectrum of the closest 4FGL source, 4FGL J0340.4+5302, by a synchro-curvature emission formalism typically used in the case of GeV pulsars. Escape-limited hadronic interaction between protons accelerated in an old, now invisible SNR and cold protons inside associated molecular clouds (MCs) and leptonic emission from a putative TeV halo was explored to explain the multi-wavelength (MWL) spectral energy distribution (SED) observed from the LHAASO source region. We have further discussed possible observational avenues that can be explored in the near future and predicted the outcome of those observational efforts from the model explored in this paper.

description: We study incentives for information sharing (about uncertain future demand for final output) among firms in imperfectly competitive markets for farm output. Information sharing generally leads to increases in expected total welfare but may reduce expected firm profits. Even when expected firm profits increase, information sharing does not represent equilibrium behavior because firms face a prisoner?s dilemma in which it is privately rational for each firm to withhold information, given that other firms report truthfully. This equilibrium can be overcome if firms commit to simultaneously reporting their information and if reports are verifiable. We argue that agricultural bargaining associations serve both these roles.

description: The government of Indonesia, like many governments in developing countries, has intervened in food markets to control an stabilize food prices. And recently, the government has had to reduce input and food subsidies due to an increasing fiscal deficit. The resulting food price increases have had effects on consumers that differ among income groups. This paper develops a theoretically consistence methodology to measure changes in different income groups' welfare cause by the adoption of alternative food pricing policies. Households were classified according to expenditure behavior. We obtained estimates of demand parameters for each income class using Indonesian household level expenditure survey data, and evaluated welfare changes from the estimated parameters. The different income groups consumed different types of foods and had different demand response to prices and income. The results show the impotence of considering distributional effects of policy changes and of developing appropriate targeting of food policies.
Andreev Reflection in Fermi Arc Surface States of Weyl Semimetals

description: Fermi arc surface states are the hallmark of Weyl semimetals, whose identification is usually challenged by their coexistence with gapless bulk states. Surface transport measurements by fabricating setups on the sample boundary provide a natural solution to this problem. Here, we study the Andreev reflection (AR) in a planar normal metal-superconductor junction on the Weyl semimetal surface with a pair of Fermi arcs. For a conserved transverse momentum, the occurrence of normal reflection depends on the relative orientation between the Fermi arcs and the normal of the junction, which is a direct result of the disconnected Fermi arcs. Consequently, a crossover from the suppressed to perfect AR occurs with varying the orientation of the planar junction, giving rise to a change from double-peak to plateau structure in conductance spectra. Moreover, such a crossover can be facilitated by imposing a magnetic field, making electrons slide along the Fermi arcs so as to switch between two regimes of the AR. Our results provide a decisive signature for the detection of Fermi arcs and open the possibilities of exploring novel phenomenology through their interplay with superconductivity.

description: We applied the migration approach to credit scoring measurement to determine how ratings, focused on farm characteristics such as farm size, age, and farm business type, change across business cycles. The empirical results from analyzing migration matrices using data from FBFM suggest that old, large and grain farms are more likely to upgrade their classes, while young, small, livestock farms are likely to downgrade. The migration matrices for each characteristic across the business cycles show that all farm businesses (except small, livestock farms) have a tendency to deteriorate during the recession cycles regardless of their characteristics.

description: Understanding the relationship between soil fertility dynamics and crop response is conceptually appealing. Even more appealing is comprehension of the spatial and temporal heterogeneity of these connections over a production surface and across seasons. Knowledge of these interactions is complicated because nutrient carryover dynamics and crop response to inputs are determined simultaneously on the one-hand, and sequentially on the other. A second problem enters when crops are rotated, for example, in the corn-soybean system commonly practiced in the Corn Belt. This paper examines the nutrient carryover-crop response nexus using data from a corn-soybean, variable-rate nitrogen (N) and phosphorous (P) experiment conducted over five years. Site-specific corn response to N and P and soybean response to P are simultaneously estimated with a P carryover equation. These estimates are used in a dynamic programming model to map site-specific optimal N and P fertilizer policies, soil P evolution, and profitability. The net present value of managing N and P site-specifically is compared to a strategy where these inputs are managed uniformly following extension guidelines. The results suggest that when P-carryover is managed, site-specific returns to the variable-rate strategies are higher than returns to a conventional, uniform strategy.

description: Textiles and apparel trade has been governed by the Multi-Fiber Arrangement (MFA) for three decades. Trade restrictions have generated substantial welfare losses and price wedges in exporting and importing countries through trade distortions. Beginning in 1995, textiles and apparel trade underwent fundamental changes. MFA quota will be removed by Jan 2005 according to World Trade Organization's Agreement on Textiles and Clothing (ATC). This study established an equilibrium displacement model to investigate the impact on textile and cotton sectors of different countries and country-groups of removing the MFA quota. The model specifies the basic linkages of textile and cotton markets in the United States, China and three other country-groups. With different parameter values for U.S. textile supply elasticity, assumptions about foreign cotton exporters' reaction and changes in the U.S. loan deficiency payment, alternative scenarios in the short run and long run are computed to predict changes in domestic and import demand for textiles and apparel, import demand for U.S. cotton, domestic and import price of textiles and apparel, U.S. cotton price and adjusted world cotton price. Generally, results indicated increased import demand for U.S. cotton, higher textiles/apparel export supply from China, decreased domestic demand for U.S. cotton, and lower U.S. domestic demand for textiles and apparel. However, both textile prices and cotton prices had positive or negative changes depending on different scenarios.

description: Safety remains a central obstacle preventing widespread use of RL in the real world: learning new tasks in uncertain environments requires extensive exploration, but safety requires limiting exploration. We propose Recovery RL, an algorithm which navigates this tradeoff by (1) leveraging offline data to learn about constraint violating zones before policy learning and (2) separating the goals of improving task performance and constraint satisfaction across two policies: a task policy that only optimizes the task reward and a recovery policy that guides the agent to safety when constraint violation is likely. We evaluate Recovery RL on 6 simulation domains, including two contact-rich manipulation tasks and an image-based navigation task, and an image-based obstacle avoidance task on a physical robot. We compare Recovery RL to 5 prior safe RL methods which jointly optimize for task performance and safety via constrained optimization or reward shaping and find that Recovery RL outperforms the next best prior method across all domains. Results suggest that Recovery RL trades off constraint violations and task successes 2 - 20 times more efficiently in simulation domains and 3 times more efficiently in physical experiments.

The Green-Schwarz mechanism is implemented without introducing distributions. The importance of the supersymmetry anomaly in constructing the low energy action is discussed and it is argued that a recently proposed action for heterotic $M$-theory gives a supersymmetric theory to all orders in the gravitational coupling $κ$.

description: Derived demand relationships among four weight categories of feeder cattle entering Texas feedlots and feed were examined using a Generalized McFadden dual cost function specified as an error correction model. Relationships among own- and cross-price elasticities provide evidence for at least two cattle feeding enterprises, feeding lightweight feeder cattle (calves) and feeding heavier cattle. These results indicate systematic differences in demand relationships among the different weight classes, providing explanation and insight into mixed results from earlier studies. Seasonality differed across weight categories, providing additional support for multiple cattle feeding enterprises. A third step was added to the Engle-Granger two-step estimation procedure to incorporate information provided in the second step.

description: Recent studies have revealed that the randomness-induced quantum spin liquid (QSL)-like state is stabilized in certain frustrated quantum magnets in two and three dimensions. In order to clarify the nature of this gapless QSL-like state, we investigate both zero- and finite-temperature properties of the random-bond one-dimensional (1D) $s=12$ Heisenberg model with the competing nearest-neighbor and next-nearest-neighbor antiferromagnetic interactions, $J_1$ and $J_2$, by means of the exact diagonalization, density-matrix renormalization-group and Hams--de Raedt methods. We find that, on increasing the frustration $J_2$, the gapless nonmagnetic state stabilized in the unfrustrated model with $J_2=0$, the {\it unfrustrated\} random-singlet (RS) state, exhibits a phase transition into different gapless nonmagnetic state, the {\it frustrated\} RS state. This frustrated RS state in 1D has properties quite similar to the randomness-induced QSL-like state recently identified in 2D and 3D frustrated magnets exhibiting the $T$-linear low-temperature ($T$) specific heat, while the unfrustrated RS state is more or less specific to the unfrustrated 1D system exhibiting the $\sim 1(\log T)^3$ low-$T$ specific heat. Universal features and the robustness against perturbations of the frustrated RS state are emphasized.

description: Well-designed and enforceable intellectual property rights (IPRs) provide economic incentives for research and development (R&D). Despite the apparent benefits to the existence of strong IPRs, many countries have a poor record in IPR protection. This paper develops a game-theoretic model of heterogeneous producers and endogenous innovators to analyze the causes and consequences of IPR infringement. Analytical results show that IPR infringement affects pricing and welfare in the market. The optimal IPR protection for the government depends not only on the pricing decision of the innovator, but also on its country size and its conjecture about the policy of other governments. A government can only use IPR protection as a strategic trade policy tool if the innovator can price discriminate.

description: We estimate a system of equation model to understand the factors that influence the loss of agricultural land to non-agricultural uses in the Southeast United States. This is done by analyzing the complex relationship between population, employment, and agricultural land density for the 1990-2000 period. From the results, it can be noted that growth in employment over time and the expansion of residential housing have to be compromised with the agricultural sector on the use and allocation of land.

Symmetry of Anomalous Dimension Matrices for Colour Evolution of Hard Scattering Processes

description: In a recent paper, Dokshitzer and Marchesini rederived the anomalous dimension matrix for colour evolution of $gg \to gg$ scattering, first derived by Kidonakis, Oderda and Sterman. They noted a weird symmetry that it possesses under interchange of internal (colour group) and external (scattering angle) degrees of freedom and speculated that this may be related to an embedding into a context that correlates internal and external variables such as string theory. In this short note, I point out another symmetry possessed by all the colour evolution anomalous dimension matrices calculated to date. It is more prosaic, but equally unexpected, and may also point to the fact that colour evolution might be understood in some deeper theoretical framework. To my knowledge it has not been pointed out elsewhere, or anticipated by any of the authors calculating these matrices. It is simply that, in a suitably chosen colour basis, they are complex symmetric matrices.

description: The modeling of nuclear reactions and radioactive decays in astrophysical or earth-based conditions requires detailed knowledge of the masses of essentially all nuclei. Microscopic mass models based on nuclear energy density functionals (EDFs) can be descriptive and used to provide this information. The concept of intrinsic symmetry breaking is central to the predictive power of EDF approaches, yet is generally not exploited to the utmost by mass models because of the computational demands of adjusting up to about two dozen parameters to thousands of nuclear masses. We report on a first step to bridge the gap between what is presently feasible for studies of individual nuclei and large-scale models: we present a new Skyrme-EDF-based model that was adjusted using a three-dimensional coordinate-space representation, for the first time allowing for both axial and triaxial deformations during the adjustment process. To compensate for the substantial increase in computational cost brought by the latter, we have employed a committee of multilayer neural networks to model the objective function in parameter space and guide us towards the overall best fit. The resulting mass model BSkG1 is computed with the EDF model independently of the neural network. It yields a root mean square (rms) deviation on the 2457 known masses of 741 keV and an rms deviation on the 884 measured charge radii of 0.024 fm.

description: Synchrotron emission is one of few observable tracers of galactic magnetic fields (\textbf{B}) and cosmic rays (CRs). Much of our understanding of \textbf{B} in galaxies comes from utilizing synchrotron observations in conjunction with several simplifying assumptions of equipartition models, however it remains unclear how well these assumptions hold, and what \textbf{B} these estimates physically represent. Using FIRE simulations which self consistently evolve CR proton, electron, and positron spectra from MeV to TeV energies, we present the first synthetic synchrotron emission predictions from simulated L$_{*}$ galaxies with "live" spectrally-resolved CR-MHD. We find that synchrotron emission can be dominated by relatively cool and dense gas, resulting in equipartition estimates of \textbf{B} with fiducial assumptions underestimating the "true" \textbf{B} in the gas that contributes the most emission by factors of 2-3 due to small volume filling factors. Motivated by our results, we present an analytic framework that expands upon equipartition models for estimating \textbf{B} in a multi-phase medium. Comparing our spectrally-resolved synchrotron predictions to simpler spectral assumptions used in galaxy simulations with CRs, we find that spectral evolution can be crucial for accurate synchrotron calculations towards galactic centers, where loss terms are large.

description:
Granville and Vance Counties in North Carolina face significant challenges related to food insecurity, economic stability, and the mental health of the youth within these communities. In Vance County, 17.8% of children experience food insecurity, exceeding the state average of 14.9%, while unemployment rates in Granville (5.6%) and Vance (7.5%) surpass the state average of 4.5% (NCIPH, 2023). Additionally, 25% of students report symptoms of anxiety and depression which highlights the urgent need for early intervention (2021). 


Limitations in policy and funding impact efforts to reduce Adverse Childhood Experiences (ACEs), emphasizing the need for advocacy to enhance mental health support and improve resource allocation. Research indicates that students suspended between the grades 7-12 have an increased risk of incarceration by the age of 26 (Hemez et al., 2021). This emphasizes the importance of school-based interventions and data-driven policies. By fostering partnerships and implementing CQI, this initiative aims to enhance long-term health outcomes by disrupting cycles of trauma and strengthening resilience with the communities of Granville and Vance Counties. 


The project implements a data based coordinated strategy with community partnership with policy advocacy and continuous quality improvement (CQI) to decrease ACEs effects while enhancing mental well being. The initiative focuses on early intervention combined with specific support services and inclusive program design to construct resilience while decreasing disparities and enhancing long term health results. The approach focuses on creating lasting systems changes and sustainable infrastructure to tackle structural inequities which will produce better health outcomes for children and families in these rural counties.
