description: The green industry comprises the production and marketing of woody ornamentals, greenhouse, and turfgrass-related products, and landscape and horticultural services. The industry is market oriented with prospects for future growth. Many state trade organizations have become interested in better measurement of the industry's economic contribution. The contribution of major industry sectors to the Louisiana economy are quantified with a state input-output model. Also presented are study results that are mainly based on readily available data sources. Results suggest that the state industry made a strong contribution to economic activity comparable in size to that of other major agricultural commodities.
Highlights of Symmetry Groups

Subjects: subject: Mathematical Physics (math-ph)

description: The concepts of symmetry and symmetry groups are at the heart of several developments in modern theoretical and mathematical physics. The present paper is devoted to a number of selected topics within this framework: Euclidean and rotation groups; the properties of fullerenes in physical chemistry; Galilei, Lorentz and Poincare groups; conformal transformations and the Laplace equation; quantum groups and Sklyanin algebras. For example, graphite can be vaporized by laser irradiation, producing a remarkably stable cluster consisting of 60 carbon atoms. The corresponding theoretical model considers a truncated icosahedron, i.e. a polygon with 60 vertices and 32 faces, 12 of which are pentagonal and 20 hexagonal. The Carbon 60 molecule obtained when a carbon atom is placed at each vertex of this structure has all valences satisfied by two single bonds and one double bond. In other words, a structure in which a pentagon is completely surrounded by hexagons is stable. Thus, a cage in which all 12 pentagons are completely surrounded by hexagons has optimum stability. On a more formal side, the exactly solvable models of quantum and statistical physics can be studied with the help of the quantum inverse problem method. The problem of enumerating the discrete quantum systems which can be solved by the quantum inverse problem method reduces to the problem of enumerating the operator-valued functions that satisfy an equation involving a fixed solution of the quantum Yang--Baxter equation. Two basic equations exist which provide a systematic procedure for obtaining completely integrable lattice approximations to various continuous completely integrable systems. This analysis leads in turn to the discovery of Sklyanin algebras.

description: We present an algorithm for the solution of a simultaneous space-time discretization of linear parabolic evolution equations with a symmetric differential operator in space. Building on earlier work, we recast this discretization into a Schur-complement equation whose solution is a quasi-optimal approximation to the weak solution of the equation at hand. Choosing a tensor-product discretization, we arrive at a remarkably simple linear system. Using wavelets in time and standard finite elements in space, we solve the resulting system in linear complexity on a single processor, and in polylogarithmic complexity when parallelized in both space and time. We complement these theoretical findings with large-scale parallel computations showing the effectiveness of the method.

description: This article shows how the solution to the promotion problem--the problem of locating the optimal level of advertising in a downstream market--can be derived simply, empirically, and robustly through the application of some simple calculus and Bayesian econometrics. We derive the complete distribution of the level of promotion that maximizes producer surplus and generate recommendations about patterns as well as levels of expenditure that increase net returns. The theory and methods are applied to quarterly series (1978:2S1988:4) on red meats promotion by the Australian Meat and Live-Stock Corporation. A slightly different pattern of expenditure would have profited lamb producers.

description: Existing policy allows interstate dairy compacts if they serve a compelling public interest. Compact supporters argue consumers benefit from retail price stability, but no supporting evidence was found. Milk demand systems were estimated using scanner data and four measures of price volatility. Price volatility defined as forecast errors influenced demand, but did not systematically depress demand. Response was more elastic to unanticipated than anticipated price changes, possibly explaining the higher elasticities often observed in scanner data studies.

description: We propose a passively self-error-rejecting single-qubit transmission scheme for an arbitrary polarization state of a single qubit over a collective-noise channel, without resorting to additional qubits and entanglement. By splitting a single qubit into some wavepackets with some Mach-Zehnder interferometers, we can obtain an uncorrupted state with a success probability approaching 100% via postselection in different time bins, independent of the parameters of collective noise. It is simpler and more flexible than the schemes utilizing decoherence-free subspace and those with additional qubits. One can directly apply this scheme to almost all quantum communication protocols based on single photons or entangled photon systems against a collective noise.

description: The advent of mad cow disease in Canada in the United States raises numerous concerns regarding consumer reaction to information in the United States. To examine the role of consumer reaction to information we examine the response of price spreads in the U.S. beef market to a Food Safety Index derived from Lexis-Nexis. Specifically, we estimate a vector error correction model to examine the long and short-run effect of news on price spreads. Our results indicate that informational shocks are fairly transient in the retail prices, but persist at the wholesale and farm level.

description: A core tenet of interprofessional collaborative practice (IPCP) is that efficient and effective teams are critical for the delivery of high-quality, patient-centered care. Although palliative care has a history of excellent care, increasing demands and larger patient loads are challenging teams to adapt and strengthen team functioning in hospital settings. The purpose of this qualitative study was to better understand the IPCP contributions of advanced palliative social workers (PSWs) through the eyes of their colleagues. Twenty-four interprofessional palliative care (IPPC) team members from other professions (i.e. nurse practitioners, physicians, physician assistants) from 16 hospitals across the U.S. participated in 20-minute semi-structured interviews. The Patient-Centered Clinical Method (PCCM) was used as a conceptual model to aid in the interpretation of the data. This model illuminated the centrality of PSWs’ role in building and sustaining a therapeutic alliance between the patient and the IPPC team, through assessing and promoting care that centers the patient’s experience with illness, creating space to initiate, process and revisit difficult healthcare conversations and helping to modulate the pace and intensity of emotionally laden discussions. PSWs also support the therapeutic relationship with the IPPC team by providing continuity and connection across and during the hospital experience and supporting the well-being of the IPPC team. This study offers novel insights into how PSWs contribute to patient-centered IPPC and furthers the articulation of the role of PSWs in hospital settings.

description: Assume that all spaces and maps are localised at a fixed prime $p$. We study the possibility of generating a universal space $U(X)$ from a space $X$ which is universal in the category of homotopy associative, homotopy commutative H-spaces in the sense that any map f:X->Y to a homotopy associative, homotopy commutative H-space extends to a uniquely determined H-map F: U(X)->Y. Developing a method for recognising certain universal spaces, we show the existence of the universal space F_2(n) of a certain three-cell complex L. Using this specific example, we derive some consequences for the calculation of the unstable homotopy groups of spheres, namely, we obtain a formula for the d_1-differential of the EHP-spectral sequence valid in a certain range.

description:
For decades, multiple anthropogenic stressors have threatened the Galápagos Islands. Widespread marine pollution such as oil spills, persistent organic pollutants, metals, and ocean plastic pollution has been linked to concerning changes in the ecophysiology and health of Galápagos species. Simultaneously, illegal, unreported, and unregulated fishing are reshaping the composition and structure of endemic and native Galápagos pelagic communities. In this novel review, we discuss the impact of anthropogenic pollutants and their associated ecotoxicological implications for Galápagos species in the face of climate change stressors. We emphasize the importance of considering fishing pressure and marine pollution, in combination with climate-change impacts, when assessing the evolutionary fitness of species inhabiting the Galápagos. For example, the survival of endemic marine iguanas has been negatively affected by organic hydrocarbons introduced via oil spills, and endangered Galápagos sea lions exhibit detectable concentrations of DDT, triggering potential feminization effects and compromising the species' survival. During periods of ocean warming (El Niño events) when endemic species undergo nutritional stress, climate change may increase the vulnerability of these species to the impacts of pollutants, resulting in the species reaching its population tipping point. Marine plastics are emerging as a deleterious and widespread threat to endemic species. The Galápagos is treasured for its historical significance and its unparalleled living laboratory and display of evolutionary processes; however, this unique and iconic paradise will remain in jeopardy until multidisciplinary and comprehensive preventative management plans are put in place to mitigate and eliminate the effects of anthropogenic stressors facing the islands today. We present a critical analysis and synthesis of anthropogenic stressors with some progress from local and international institutional efforts and call to action more precautionary measures along with new management philosophies focused on understanding the processes of change through research to champion the conservation of the Galápagos.
On the Possible Evolutionary History of the Water Ocean on Venus

description: We have investigated the possible evolutional history of the water ocean on Venus, adopting the one dimensional radiative-convective model,including the parameters as albedo and relative humidity. Under this model, it has the possibility that the habitable zone could include Venus. It could continue for $\sim 1$ Gy in faint young solar flux increasing, with modest parameters such as albedo = 0.3, relative humidity (RH=1), and $p_{n0}=10^5 $Pa. If we relax parameters considering the 3-Dimensional calculations, the ocean could exist there longer than $\sim$ 4.6 Gy. In such cases, we have to consider the cause of runaway other than just solar luminosity increasing. It is important to investigate Venus history for the coming future of Earth and observations of exoplanets for their historical habitable zones.

description: We propose a methodological framework to study the dynamics of inter-regional investment flow in Europe from a Complex Networks perspective, an approach with recent proven success in many fields including economics. In this work we study the network of investment stocks in Europe at two different levels: first, we compute the inward-outward investment stocks at the level of firms, based on ownership shares and number of employees; then we estimate the inward-outward investment stock at the level of regions in Europe, by aggregating the ownership network of firms, based on their headquarter location. Despite the intuitive value of this approach for EU policy making in economic development, to our knowledge there are no similar works in the literature yet. In this paper we focus on statistical distributions and scaling laws of activity, investment stock and connectivity degree both at the level of firms and at the level of regions. In particular we find that investment stock of firms is power law distributed with an exponent very close to the one found for firm activity. On the other hand investment stock and activity of regions turn out to be log-normal distributed. At both levels we find scaling laws relating investment to activity and connectivity. In particular, we find that investment stock scales with connectivity in a similar way as has been previously found for stock market data, calling for further investigations on a possible general scaling law holding true in economical networks.

description: While rural health-care settings are said to be ideal places for the facilitation of interprofessional education and collaborative practice (IPECP) in students, little is known about the rural-IPECP interface. This study explored this interface through student and clinical educator experiences following implementation of a structured IPECP student placement model. Data were gathered through 11 focus groups with 34 students and 24 clinical educators. Content analysis was used to analyze data and two categories were developed for reporting. The power of place and space, highlighting the importance of flexibility, co-location, and lack of hierarchy in promoting IPECP, as well as the role of shared accommodation in enhancing social connectedness within and outside placement were highlighted. This study unpacks the characteristics of rural health-care settings that make it ideal for IPECP despite the resource constraints. Future studies can investigate the rural-IPECP interface through a patient lens.

description: We investigate the complete universe evolution in the framework of $f(T)$ cosmology. We first study the requirements at the kinematic level and we introduce a simple scale factor with the necessary features. Performing a detailed analysis of the phase portrait we show that the universe begins in the infinite past from a phase where the scale factor goes to zero but the Hubble parameter goes to a constant, and its derivative to zero. Since these features resemble those of the Pseudo-Rip fate but in a reverted way, we call this initial phase as Pseudo-Bang. Then the universe evolves in a first inflationary phase, a cosmological turnaround and a bounce, after which we have a second inflationary regime with a successful exit. Subsequently we obtain the standard thermal history and the sequence of radiation, matter and late-time acceleration epochs, showing that the universe will result in an everlasting Pseudo-Rip phase. Finally, taking advantage of the fact that the field equations of $f(T)$ gravity are of second order, and therefore the corresponding autonomous dynamical system is one dimensional, we incorporate the aforementioned kinematic features and we reconstruct the specific $f(T)$ form that can dynamically generate the Pseudo-Bang cosmological scenario. Lastly, we examine the evolution of the primordial fluctuations showing that they are initially sub-horizon, and we show that the total fluid does not exhibit any singular behaviour at the phantom crossing points, while the torsional fluid experiences them as Type II singular phases.

description: In Vietnam, each primary care community health center (CHC) consists of a multi-professional team with six disciplines, including a physician, assistant physician, nurse, pharmacist, midwife, and Vietnamese traditional physician, who are able to meet the majority of patient’s needs at the primary care level. How they collaborate, especially in chronic disease management (CDM), is still limited described in the literature. This study aims to gain insight into the perceptions and the experiences of primary health care providers (PHCPs) toward interprofessional collaboration (IPC) in CDM in CHCs in (Hue) Vietnam. A qualitative study of descriptive phenomenology was performed using two focus groups and 15 semi-structured interviews with PHCPs from six professions relevant to CDM in CHCs. The data were analyzed using NVivo 12.0 with a thematic analysis method by a multiprofessional research team. From the analysis, the data were classified into three main themes: “lack of collaborative practice,” “knowledge,” and “facilitators and barriers to IPC.” This study provided evidence of the awareness that actual collaboration in daily care is fragmentarily organized and that PHCPs try to finish their tasks within their profession. PHCPs work multiprofessionally and lack shared decision-making in patient-centered care. There is a need to develop an interprofessional education program and training to address these deficiencies in the Vietnamese context to improve interprofessional collaboration in health care.

description: Methyl bromide is a critical soil fumigant used in the production of several fresh fruit and vegetables grown in the U.S. The U.S. Clean Air Act of 1992, as amended in 1998, requires that methyl bromide be phased out of use by 2005. A mathematical programming model of the North American vegetable market indicates that the elimination of methyl bromide will have significant impacts on U.S. growers of fruit and vegetables that rely on methyl bromide for soil fumigation purposes. The schedule for eliminating methyl bromide has resulted in a 50% decline in methyl bromide availability and has resulted in significant increases in the price of methyl bromide. The vegetable industry has not felt the impact that the reduction in methyl bromide may have, however, as increases in price have partially offset the decline in overall availability. Increases in price have reduced the use of methyl bromide for lower valued uses, and new application technologies have reduced the required application rate of methyl bromide for effective control of pests and diseases. Larger impacts on the fruit and vegetable industry are expected as the 20% reduction in 2003 and the total elimination in 2005 are imposed.
Random-Matrix Theory of Electron Transport in Disordered Wires with Symplectic Symmetry

description: The conductance of disordered wires with symplectic symmetry is studied by a random-matrix approach. It has been believed that Anderson localization inevitably arises in ordinary disordered wires. A counterexample is recently found in the systems with symplectic symmetry, where one perfectly conducting channel is present even in the long-wire limit when the number of conducting channels is odd. This indicates that the odd-channel case is essentially different from the ordinary even-channel case. To study such differences, we derive the DMPK equation for transmission eigenvalues for both the even- and odd- channel cases. The behavior of dimensionless conductance is investigated on the basis of the resulting equation. In the short-wire regime, we find that the weak-antilocalization correction to the conductance in the odd-channel case is equivalent to that in the even-channel case. We also find that the variance does not depend on whether the number of channels is even or odd. In the long-wire regime, it is shown that the dimensionless conductance in the even-channel case decays exponentially as --> 0 with increasing system length, while --> 1 in the odd-channel case. We evaluate the decay length for the even- and odd-channel cases and find a clear even-odd difference. These results indicate that the perfectly conducting channel induces clear even-odd differences in the long-wire regime.

Optical studies of critical phenomena in fluids

Publisher: name: University of British Columbia

description: Accurate optical techniques were employed to study the behaviour of the binary liquid mixture n-heptane+nitrobenzene (C₇H₁₆ + C₆H₅NO₂) and of the pure fluid 1,1-difluoroethylene (C₂H₂F₂) near their respective critical regions. It is found that, in the region of reduced temperature, t = (T[sub c] — T)/T[sub c] < 3 x 10 ⁻⁴ , the order parameter ΔΦ[sub H] for the binary mixture follows a power law ΔΦ[sub H]« t[sup β], with a leading exponent β = 0.367 ± 0.006, which is higher than the predicted theoretical value of β = 0.326 ± 0.002. A careful study of the effect of refractive index gradients caused by the Earth's gravitational field, potential variation of the optical thickness of the sample cells due to wetting of the cell walls by one the phases, and the long thermal equilibration times of binary mixtures has failed to resolve the disagreement between β measured on n-heptane+nitrobenzene and its theoretical value. A significant feature of this investigation is the novel application of an optical technique (the image plane technique) for studying critical phenomena in transparent binary liquids. The Lorentz-Lorenz function, £, of 1,1-difluoroethylene was measured in order to determine the fluid's density from its refractive index. The quantity £. is found to vary by about 1.4% with density of the fluid, p, with a gentle maximum at a density slightly higher than the critical density, p[sub c]. The density measurements were then used to construct the coexistence curve for this material. The coexistence curve of C₂H₂F₂ was measured with the 'Lorentz-Lorenz' experiment and with a new apparatus combining two complementary optical methods, the prism cell technique and the focal plane technique, into one. The measurements carried out on C₂H₂F₂ in this thesis serve as a test of this apparatus. The order parameter data of C₂H₂F₂ are described accurately by a scaling power law in terms of the reduced temperature t, with the critical exponents at their theoretical values. The coexistence curve data^ taken simultaneously with the two combined techniques agree well with each over the whole range of temperature investigated.

description: An effective perception system is a fundamental component for farming robots, as it enables them to properly perceive the surrounding environment and to carry out targeted operations. The most recent methods make use of state-of-the-art machine learning techniques to learn a valid model for the target task. However, those techniques need a large amount of labeled data for training. A recent approach to deal with this issue is data augmentation through Generative Adversarial Networks (GANs), where entire synthetic scenes are added to the training data, thus enlarging and diversifying their informative content. In this work, we propose an alternative solution with respect to the common data augmentation methods, applying it to the fundamental problem of crop/weed segmentation in precision farming. Starting from real images, we create semi-artificial samples by replacing the most relevant object classes (i.e., crop and weeds) with their synthesized counterparts. To do that, we employ a conditional GAN (cGAN), where the generative model is trained by conditioning the shape of the generated object. Moreover, in addition to RGB data, we take into account also near-infrared (NIR) information, generating four channel multi-spectral synthetic images. Quantitative experiments, carried out on three publicly available datasets, show that (i) our model is capable of generating realistic multi-spectral images of plants and (ii) the usage of such synthetic images in the training process improves the segmentation performance of state-of-the-art semantic segmentation convolutional networks.

description: Sugar is a major commodity, produced and traded around the world, but it is no longer the only sweetener. For example, in the United States, roughly 50 percent of the sweetener market is made up of high fructose corn syrup (HFCS), which is also making inroads into Mexico. This is not the case, however, for the European Union and countries such as Brazil, which dominates the world sugar market in almost all aspects (Schmitz, 2002). In the United States, 8 to 10 percent of the U.S. corn crop goes into HFCS production, with roughly the same percentage of corn being used for the production of ethanol (Schmitz and Polopolous, 1999). In Brazil, however, sugarcane, rather than corn, is used in the production of ethanol. Because of relative price differences for corn and sugar, along with government subsidies, countries like Brazil will remain heavily dependent on sugar for both its sweetener needs and ethanol production.

description: Florida ranked ninth in the U.S. in agricultural receipts for the year 2000, and ranked first or second in receipts for 12 of the nation's top 25 agricultural commodities. Ten of these twelve leading agricultural commodities were fresh fruits or vegetables, and combined, they represented over 45 percent of the state's agricultural receipts in 2000. Despite Florida's preeminent standing as a producer of fresh fruits and vegetables, it's future leadership in this industry is less clear. In real terms, Florida's annual agricultural receipts have declined from $7.41 billion in 1992, to $6.42 billion in 2001. In 2000, receipts fell by over $521 million, the sharpest one-year drop since 1990. The overall trend in fresh vegetable receipts for the State has been downward since 1992 and receipts for fresh tomatoes, the state's most important fresh vegetable, fell by almost half over the same period. With nearly 90 percent of its receipts from fresh vegetables coming from out-of-state sales, it is estimated that the vegetable industry generated a total economic output impact of $3.14 billion for the state in 2001. Changes in agricultural policy or market conditions can and will continue to have a significant impact on Florida's economy. Given that the bulk of many fresh vegetables are produced within a handful of counties within the state, even minor changes in policy or market prices can result in dramatic consequences for local producers and the economies of individual counties.

description: White light phase-shifting interference microscopy (WL-PSIM) is a prominent technique for high-resolution quantitative phase imaging (QPI) of industrial and biological specimens. However, multiple interferograms with accurate phase-shifts are essentially required in WL-PSIM for measuring the accurate phase of the object. Here, we present single-shot phase-shifting interferometric techniques for accurate phase measurement using filtered white light phase-shifting interference microscopy (F-WL-PSIM) and deep neural network (DNN). The methods are incorporated by training the DNN to generate 1) four phase-shifted frames and 2) direct phase from a single interferogram. The training of network is performed on two different samples i.e., optical waveguide and MG63 osteosarcoma cells. Further, performance of F-WL-PSIM+DNN framework is validated by comparing the phase map extracted from network generated and experimentally recorded interferograms. The current approach can further strengthen QPI techniques for high-resolution phase recovery using a single frame for different biomedical applications.

description: American college football faces a conflict created by the desire to stage national championship games between the best teams of a season when there is no conventional playoff system to decide which those teams are. Instead, ranking of teams is based on their record of wins and losses during the season, but each team plays only a small fraction of eligible opponents, making the system underdetermined or contradictory or both. It is an interesting challenge to create a ranking system that at once is mathematically well-founded, gives results in general accord with received wisdom concerning the relative strengths of the teams, and is based upon intuitive principles, allowing it to be accepted readily by fans and experts alike. Here we introduce a one-parameter ranking method that satisfies all of these requirements and is based on a network representation of college football schedules.

description: This study details a new, network-level optimization tool aimed at supporting transportation agencies in their efforts to reduce the global warming potential of their road pavement infrastructure. Through a two-stage bottom-up algorithm that integrates with a comprehensive cradle-to-grave life cycle assessment, the proposed tool learns optimal management policies for individual pavement sections and uses that information to guide network-level allocation choices. Through a realistic case study based on data made available by a state department of transportation, this study demonstrates that the proposed modelling approach identifies management strategies expected to reduce the global warming potential of a pavement network by up to 4.8% over 20 years relative to a more traditional, reactive management approach. The resulting model presented in this paper can support agencies in achieving ambitious targets to reduce the global warming potential of their paved infrastructure systems.

Enabling Zero-shot Multilingual Spoken Language Translation with Language-Specific Encoders and Decoders

description: Current end-to-end approaches to Spoken Language Translation (SLT) rely on limited training resources, especially for multilingual settings. On the other hand, Multilingual Neural Machine Translation (MultiNMT) approaches rely on higher-quality and more massive data sets. Our proposed method extends a MultiNMT architecture based on language-specific encoders-decoders to the task of Multilingual SLT (MultiSLT). Our method entirely eliminates the dependency from MultiSLT data and it is able to translate while training only on ASR and MultiNMT data. Our experiments on four different languages show that coupling the speech encoder to the MultiNMT architecture produces similar quality translations compared to a bilingual baseline ($\pm 0.2$ BLEU) while effectively allowing for zero-shot MultiSLT. Additionally, we propose using an Adapter module for coupling the speech inputs. This Adapter module produces consistent improvements up to +6 BLEU points on the proposed architecture and +1 BLEU point on the end-to-end baseline.
On the nature of the stock market : simulations and experiments

description: Over the last few years there has been a surge of activity within the physics community in the emerging field of Econophysics—the study of economic systems from a physicist's perspective. Physicists tend to take a different view than economists and other social scientists, being interested in such topics as phase transitions and fluctuations. In this dissertation two simple models of stock exchange are developed and simulated numerically. The first is characterized by centralized trading with a market maker. Fluctuations are driven by a stochastic component in the agents' forecasts. As the scale of the fluctuations is varied a critical phase transition is discovered. Unfortunately, this model is unable to generate realistic market dynamics. The second model discards the requirement of centralized trading. In this case the stochastic driving force is Gaussian-distributed "news events" which are public knowledge. Under variation of the control parameter the model exhibits two phase transitions: both a first- and a second-order (critical). The decentralized model is able to capture many of the interesting properties observed in empirical markets such as fat tails in the distribution of returns, a brief memory in the return series, and long-range correlations in volatility. Significantly, these properties only emerge when the parameters are tuned such that the model spans the critical point. This suggests that real markets may operate at or near a critical point, but is unable to explain why this should be. This remains an interesting open question worth further investigation. One of the main points of the thesis is that these empirical phenomena are not present in the stochastic driving force, but emerge endogenously from interactions between agents. Further, they emerge despite the simplicity of the modeled agents; suggesting complex market dynamics do not arise from the complexity of individual investors but simply from interactions between (even simple) investors. Although the emphasis of this thesis is on the extent to which multi-agent models can produce complex dynamics, some attempt is also made to relate this work with empirical data. Firstly, the trading strategy applied by the agents in the second model is demonstrated to be adequate, if not optimal, and to have some surprising consequences. Secondly, the claim put forth by Sornette et al. that large financial crashes may be heralded by accelerating precursory oscillations is also tested. It is shown that there is weak evidence for the existence of log-periodic precursors but the signal is probably too indistinct to allow for reliable predictions.

description: We propose a novel representation of differential scattering cross-sections that locally realises the direct cancellation of infrared singularities exhibited by its so-called real-emission and virtual degrees of freedom. We take advantage of the Loop-Tree Duality representation of each individual forward-scattering diagram and we prove that the ensuing expression is locally free of infrared divergences, applies at any perturbative order and for any process without initial-state collinear singularities. Divergences for loop momenta with large magnitudes are regulated using local ultraviolet counterterms that reproduce the usual Lagrangian renormalisation procedure of quantum field theories. Our representation is especially suited for a numerical implementation and we demonstrate its practical potential by computing fully numerically and without any IR counterterm the next-to-leading order accurate differential cross-section for the process $e^+ e^- \rightarrow d \bar{d}$. We also show first results beyond next-to-leading order by computing interference terms part of the N4LO-accurate inclusive cross-section of a $1\rightarrow 2+X$ scalar scattering process.

description: Gamma-ray bursts (GRBs) are rare but powerful explosions displaying highly relativistic jets. It has been suggested that a significant fraction of the much more frequent core-collapse supernovae are accompanied by comparably energetic but mildly relativistic jets, which would indicate an underlying supernova--GRB connection. We calculate the neutrino spectra from the decays of pions and kaons produced in jets in supernovae, and show that the kaon contribution is dominant and provides a sharp break near 20 TeV, which is a sensitive probe of the conditions inside the jet. For a supernova at 10 Mpc, 30 events above 100 GeV are expected in a 10 s burst in the IceCube detector.
