description: We re-analyze the precision radial velocity (RV) data of HD188015, HD114729, HD190360, HD147513 and HD208487. All these stars are supposed to host Jovian companions in long-period orbits. We test a hypothesis that the residuals of the 1-planet model of the RV or an irregular scatter of the measurements about the synthetic RV curve may be explained by the existence of additional planets in short-period orbits. We perform a global search for the best fits in the orbital parameters space with genetic algorithms and simplex method. This makes it possible to verify and extend the results obtained with an application of commonly used FFT-based periodogram analysis for identifying the leading periods. Our analysis confirms the presence of a periodic component in the RV data of HD190360 which may correspond to a hot-Neptune planet. We found four new cases when the 2-planet model yields significantly better fits to the RV data than the best 1-planet solutions. If the periodic variability of the residuals of single-planet fits has indeed a planetary origin then hot-Neptune planets may exist in these extrasolar systems. We estimate their orbital periods in the range of 7-20d and minimal masses about of 20 masses od the Earth.

description: Purpose: A 2017 CATALISE project resulted in consensus on using the term “developmental language disorder” (DLD) to describe children with unexplained language impairment. Since then, it is unclear how researchers have identified DLD and implemented DLD terminology. The current study is a scoping review to better understand the implementation of DLD terminology.Method: We identified studies (N = 265) published in American Speech-Language-Hearing Association (ASHA) journals between 2017 and 2024 that included individuals with communication difficulties in the area of language not secondary to another etiology. We extracted key information regarding study purpose and participant identification from each publication.Results: Across all publications, 58% included the term “DLD” to describe their participant(s), 22% included “specific language impairment” (SLI), 12% included “language impairment” (LI), and 8% included other terms. The majority of publications served to better understand the profile of individuals with DLD, evaluate an intervention, or report on a measurement tool related to identification of the condition. There was significant variation in the developmental domains (e.g., cognitive, social, sensory) considered when diagnosing DLD across research publications.Conclusions: This scoping review demonstrates the adoption and implementation of the term “DLD” in ASHA publications. Future efforts should prioritize increasing the consistency of identification of DLD in research, advocating for use of DLD terminology in clinical contexts, and supporting clinicians’ knowledge, identification, assessment, intervention, and advocacy related to DLD.Supplemental Material S1.

Risk and Uncertainty

description: The U.S. citrus industry faces potentially devastating losses due to diseases currently infecting or threatening citrus groves. Potential exists in the development of genetically modified citrus trees that are resistant to disease. Growers face risk not only from losses attributable to disease, but also in their decisions to invest in establishing groves. Scenarios including hypothetical disease resistant citrus cultivars as well as forecasted tree losses, fruit prices, and costs are modeled and evaluated with risk ranking to identify the potential benefit of adopting improved citrus cultivars. Returns to the grower are the primary focus, however, returns to organizations producing disease resistant cultivars are also modeled.

description: Imaging of surface adsorbed molecules is investigated as a novel detection method for matter wave interferometry with fluorescent particles. Mechanically magnified fluorescence imaging turns out to be an excellent tool for recording quantum interference patterns. It has a good sensitivity and yields patterns of high visibility. The spatial resolution of this technique is only determined by the Talbot gratings and can exceed the optical resolution limit by an order of magnitude. A unique advantage of this approach is its scalability: for certain classes of nano-sized objects, the detection sensitivity will even increase significantly with increasing size of the particle.

description: This paper analyzes historical movements in the commodity futures market and the relationship to inflation. Specifically, the relationship between the Commodity Research Bureau (CRB) Index and United States inflation is investigated. It is said that the relationship between the CRB index and the U.S. inflation rate was greater in the some periods than in another period. Then in recent times the CRB Index has proven to be a reliable early indicator of inflation. As the composition of the United States economy changes, the Commodity Research Bureau must make adjustments in order to provide a viable service.

description: The increase in the sensitivity of gravitational wave interferometers will bring additional detections of binary black hole and double neutron star mergers. It will also very likely add many merger events of black hole - neutron star binaries. Distinguishing mixed binaries from binary black holes mergers for high mass ratios could be challenging because in this situation the neutron star coalesces with the black hole without experiencing significant disruption. To investigate the transition of mixed binary mergers into those behaving more like binary black hole coalescences, we present results from merger simulations for different mass ratios. We show how the degree of deformation and disruption of the neutron star impacts the inspiral and merger dynamics, the properties of the final black hole, the accretion disk formed from the circularization of the tidal debris, the gravitational waves, and the strain spectrum and mismatches. The results also show the effectiveness of the initial data method that generalizes the Bowen-York initial data for black hole punctures to the case of binaries with neutron star companions.

description: In this letter, we propose a conceptually simple and effective dual-granularity triplet loss for visible-thermal person re-identification (VT-ReID). In general, ReID models are always trained with the sample-based triplet loss and identification loss from the fine granularity level. It is possible when a center-based loss is introduced to encourage the intra-class compactness and inter-class discrimination from the coarse granularity level. Our proposed dual-granularity triplet loss well organizes the sample-based triplet loss and center-based triplet loss in a hierarchical fine to coarse granularity manner, just with some simple configurations of typical operations, such as pooling and batch normalization. Experiments on RegDB and SYSU-MM01 datasets show that with only the global features our dual-granularity triplet loss can improve the VT-ReID performance by a significant margin. It can be a strong VT-ReID baseline to boost future research with high quality.

A Consistent Modeling of Neutrino-driven Wind with Accretion Flow onto a Protoneutron Star and its Implications for $^{56}$Ni Production

description: Details of the explosion mechanism of core-collapse supernovae (CCSNe) are not yet fully understood. There is now an increasing number of successful examples of reproducing explosions in the first-principles simulations, which have shown a slow increase of explosion energy. However, it was recently pointed out that the growth rates of the explosion energy of these simulations are insufficient to produce enough $^{56}$Ni mass to account for observations. We refer to this issue as the `nickel mass problem' (Ni problem, hereafter) in this paper. The neutrino-driven wind is suggested as one of the most promising candidates for the solution to the Ni problem in previous literature, but a multi-dimensional simulation for this is computationally too expensive to allow long-term investigations. In this paper, we first built a consistent model of the neutrino-driven wind with an accretion flow onto a protoneutron star (PNS), by connecting a steady-state solution of the neutrino-driven wind and a phenomenological mass accretion model. Comparing the results of our model with the results of first-principles simulations, we find that the total ejectable amount of the neutrino-driven wind is roughly determined within $\sim$ 1 sec from the onset of the explosion and the supplementable amount at a late phase ($t_e \gtrsim 1$ sec) remains $M_\mathrm{ej} \lesssim 0.01M_\odot$ at most. Our conclusion is that it is difficult to solve the Ni problem, by continuous injection of $^{56}$Ni by the neutrino-driven wind. We suggest that the total amount of synthesized $^{56}$Ni can be estimated robustly if simulations are followed up to $\sim 2$ seconds.

description: We consider the optimal transport problem between multivariate Gaussian stationary stochastic processes. The transportation effort is the variance of the filtered discrepancy process. The main contribution of this technical note is to show that the corresponding solution leads to a weighted Hellinger distance between multivariate power spectral densities. Then, we propose a spectral estimation approach in the case of indirect measurements which is based on this distance.

However, the absence of an international trade agreement does not reduce the need for the U.S. to comply with previous agreements.

description: Results from the analyses indicate that repealing the 7 percent grocery tax would produce modest gains in grocery sales but major increases in the purchases of other goods and services. Revenues from the sale of additional groceries would be exempt from taxes, thus producing only employment and labor income. With the state loosing almost $202 million in tax revenues, it is not clear if the gains in employment would be enough to offset the revenue losses.

description: We use molecular simulations to explore how sample dimensions and interfacial properties impact some generic aspects of the mechanical and structural behavior of nanoconfined materials. Specifically, we calculate the strain-dependent properties of minimum-energy thin-film particle configurations (i.e., inherent structures) confined between attractive, parallel substrates. We examine how the relationship between the transverse strain and the stress tensor (the equation of state of the energy landscape) depends on the properties of the film and substrate. We find that both film thickness and film-substrate attractions influence not only the mechanical properties of thin films, but also the shape and location of the "weak spots" where voids preferentially form in a film as it is strained beyond its point of maximum tensile stress. The sensitivity of weak spots to film properties suggests that nanoscale materials may be intrinsically vulnerabile to specific mechanisms of mechanical failure.

description: This paper synthesizes the evidence on cereal crop productivity in developing countries over the past 30 years and looks at future prospects for productivity growth. For more than three decades we have witnessed the phenomenal growth of cereal crop productivity in the developing world. Termed the Green Revolution, the initial phase of this growth resulted from an increase in land productivity and occurred in areas of growing land scarcity and/or areas with high land values. Significant investments in research and infrastructure development, especially irrigation, were the strategic components of this increased productivity. In the post-Green Revolution period, particularly in Asia, productivity growth has been sustained through increased input use and, more recently, through more efficient use of inputs. Lately, however, indicators show a decrease in the growth rate of productivity of two of the three primary cereals, rice and wheat. The first two sections of this paper present trends on cereal crop productivity in developing countries over the last three decades. Supporting evidence includes yield and other partial factor productivity trends and a summary of studies on total factor productivity. The third section speculates on the prospects for future growth.

description: The convolution formula is derived within the framework of the decay-chain method for decay channels with three and four particles in a final state. To get this formula exactly for unstable particle of any type one must modify the propagators of vector and spinor fields. In this work we suggest proper modifications and get the convolution formula by direct calculation. It was noted that this approach naturally arises in the model of unstable particles with random mass.

description: A 40-year-old puzzle in transition metal pentatellurides ZrTe$_5$ and HfTe$_5$ is the anomalous peak in the temperature dependence of the longitudinal resistivity, which is accompanied by sign reverses of the Hall and Seebeck coefficients. We give a plausible explanation for these phenomena without assuming any phase transition or strong interaction effect. We show that due to intrinsic thermodynamics and diluteness of the conducting electrons in these materials, the chemical potential displays a strong dependence on the temperature and magnetic field. With that, we compute resistivity, Hall and Seebeck coefficients in zero field, and magnetoresistivity and Hall resistivity in finite magnetic fields, in all of which we reproduce the main features that are observed in experiments.

The Boundary Conditions for Point Transformed Electromagnetic Invisibility Cloaks

Subjects: subject: Optics (physics.optics)

description: In this paper we study point transformed electromagnetic invisibility cloaks in transformation media that are obtained by transformation from general anisotropic media. We assume that there are several cloaks located in different points in space. Our results apply in particular to the first order invisibility cloaks introduced by Pendry et al. and to the high order invisibility cloaks introduced by Hendi et al. and by Cai et al.. We identify the appropriate {\it cloaking boundary conditions} that the solutions of Maxwell equations have to satisfy at the outside, $\partial K_+$, and at the inside, $\partial K_-$, of the boundary of the cloaked object $K$. Namely, that the tangential components of the electric and the magnetic fields have to vanish at $\partial K_+$ -what is always true- and that the normal components of the curl of the electric and the magnetic fields have to vanish at $\partial K_-$. These results are proven requiring that energy be conserved. In the case of one spherical cloak with a spherically stratified $K$ and a radial current at $\partial K$ we verify by an explicit calculation that our {\it cloaking boundary conditions} are satisfied and that cloaking of active devices holds even if the current is at the boundary of the cloaked object. As we prove our results for media that are obtained by transformation from general anisotropic media, our results apply to the cloaking of objects with active and passive devices contained in general anisotropic media, in particular to objects with active and passive devices contained inside general crystals.

description: In this study the structured laser illumination planar imaging (SLIPI) technique is combined with gas phase phosphor thermometry to measure quasi-instantaneously two-dimensional temperature fields with reduced bias from multiple scattering. Different reconstruction strategies are implemented, evaluated and compared, including a two-pulse and one-pulse SLIPI approach. A gradient-based threshold algorithm for particle detection is applied to conventional planar light sheet imaging as an alternative to reduce the bias caused by multiple scattering in seeding-free regions. As a demonstration, measurements are performed in a canonical flow configuration, consisting of a heated, turbulent, air jet surrounded by an ambient co-flow. Both air flows are seeded with the thermographic phosphor BaMgAl₁₇O₁₇:Eu²⁺.
 
Conventional light sheet imaging in the context of gas phase phosphor thermometry suffers from multiple scattering causing a significant temperature bias and low temperature sensitivity. Applying the gradient threshold algorithm removes areas without any seeding particles which improves accuracy, precision and temperature sensitivity. However, multiple scattering influences are still present and may cause an increasing bias particularly for higher seeding density. One pulse (1p) SLIPI exhibits high accuracy at intermediate precision. Multiply scattered luminescence is not fully removed and spatial resolution is lowered. Two pulse (2p) SLIPI is recommended for high temperature sensitivity and accuracy, removing impact of multiple scattering furthermost. However, 2p-SLIPI exhibits reduced temperature precision.

description: En la década del 90, el sector agropecuario mexicano generó alrededor del 5% del PBI y el 2.5% de las exportaciones. A pesar de su reducida contribución al PBI, el sector agropecuario tiene una gran importancia económica y social como generador de empleos (un 25% del empleo total), por su influencia sobre el costo de vida, la prevalencia de la pobreza rural (más del 75% de la población pobre y más del 50% de los que viven en pobreza extrema habitan en zonas rurales) y porque las exportaciones agropecuarias constituyen una fuente de ingreso importante para varias regiones, especialmente las zonas irrigadas del norte y centro del país. Desde la década del 70, algunos productores agropecuarios mexicanos, especialmente los que se integraron a cadenas exportadoras, pudieron incorporar tecnologías de punta que han sido la base de su competitividad. Pero, en general, estas tecnologías no fueron desarrolladas por las instituciones públicas de investigación sino que fueron importadas o desarrolladas por empresas privadas mexicanas. Las instituciones públicas de investigación fueron creadas para proporcionar apoyo técnico a las políticas de desarrollo agropecuario. Por esta razón, las autoridades de estas instituciones mantenían contactos fluidos con las dependencias gubernamentales de las que dependían, pero sus interacciones con agricultores y empresas ligadas al sector eran débiles. En general, esta estructura jerárquica se reproducía dentro de las instituciones y en sus relaciones con los agricultores. A partir de la década del 90, México ha hecho un esfuerzo importante para reformar su sistema público de investigación. Los cambios incluyeron nuevos incentivos para los investigadores establecidos por las principales instituciones financiadoras. Sin embargo, las reformas dentro de las propias instituciones han avanzado a paso lento, especialmente los incentivos para incrementar las interacciones con otros agentes dentro del sistema de innovación agropecuario aún no se han adecuado a las necesidades de un sector integrado a la economía mundial.

description: Let U be a given function defined on R^d and π(x) be a density function proportional to \exp -U(x). The following diffusion X(t) is often used to sample from π(x), dX(t)=-\nabla U(X(t)) dt+\sqrt2 dW(t),\qquad X(0)=x_0. To accelerate the convergence, a family of diffusions with π(x) as their common equilibrium is considered, dX(t)=\bigl(-\nabla U(X(t))+C(X(t))\bigr) dt+\sqrt2 dW(t),\qquad X(0)=x_0. Let L_C be the corresponding infinitesimal generator. The spectral gap of L_C in L^2(π) (λ(C)), and the convergence exponent of X(t) to πin variational norm (ρ(C)), are used to describe the convergence rate, where λ(C)= Sup{real part of μ\dvtxμis in the spectrum of L_C, μis not zero}, {-2.8cm}ρ(C) = Inf\biggl{ρ\dvtx\int | p(t,x,y) -π(y)| dy \le g(x) e^{ρt}\biggr}.Roughly speaking, L_C is a perturbation of the self-adjoint L_0 by an antisymmetric operator C\cdot\nabla, where C is weighted divergence free. We prove that λ(C)\le λ(0) and equality holds only in some rare situations. Furthermore, ρ(C)\le λ(C) and equality holds for C=0. In other words, adding an extra drift, C(x), accelerates convergence. Related problems are also discussed.

The known range of astronomical parameters is examined to determine whether it encompasses the existing synchrotron emission data. Given the present-day spatial extent and expansion rate of the object, it is shown that the hadronic gamma-ray flux is very sensitive to the ambient gas density N_H and that the existing H.E.S.S. upper limit requires N_H < 0.1 cm^{-3}. The strength of the amplified magnetic field downstream of the shock is about 150 μG.

Specifically, we determine the characteristic time $τ_D$ of the nonlinear susceptibility build-up due as to the Soret effect. By comparing $τ_D$ with the relaxation time provided by standard dynamic light scattering measurements we report on the decoupling of the two collective diffusion times at the two very different length scales during the aging of the out-of-equilibrium system. With this demonstration experiment we also show the potentiality of nonlinear optics measurements in the study of the late stage of arrest in soft materials.
Jupiter's composition: sign of a (relatively) late formation in a chemically evolved protosolar disk

description: It has been proposed that the enrichment in noble gases found by Galileo in Jupiter's atmosphere can be explained by their delivery inside cold planetesimals. We propose instead that this is a sign that the planet formed in a chemically evolved disk and that noble gases were acquired mostly in gaseous form during the planet's envelope capture phase. We show that the combined settling of grains to the disk midplane in the cold outer layers, the condensation of noble gases onto these grains at temperatures below 20-30K, and the evaporation from high disk altitudes effectively lead to a progressive, moderate enrichment of the disk. The fact that noble gases are vaporized from the grains in the hot inner disk regions (e.g. Jupiter formation region) is not a concern because a negative temperature gradient prevents convection from carrying the species into the evaporating region. We show that the ~2 times solar enrichment of Ar, Kr, Xe in Jupiter is hence naturally explained by a continuous growth of the planet governed by viscous diffusion in the protosolar disk in conjunction with an evaporation of the disk and its progressive enrichment on a million years timescale.

description: We present a first analysis of deep 24 micron observations with the Spitzer Space Telescope of a sample of nearly 1500 galaxies in a thin redshift slice, 0.652x10^10 solar masses) are undergoing a period of intense star formation above their past-averaged SFR. In contrast, less than 1% of equally-massive galaxies in the local universe have similarly intense star formation activity. Morphologically-undisturbed galaxies dominate the total infrared luminosity density and SFR density: at z~0.7, more than half of the intensely star-forming galaxies have spiral morphologies, whereas less than \~30% are strongly interacting. Thus, a decline in major-merger rate is not the underlying cause of the rapid decline in cosmic SFR since z~0.7. Physical properties that do not strongly affect galaxy morphology - for example, gas consumption and weak interactions with small satellite galaxies - appear to be responsible.

description: In order to evaluate the merits of the technologies developed in CENTRIC for future 6G networks, it is of crucial importance to define a set of measures that can help quantify their performance under different conditions. In addition to performance characterization, 6G aims to provide other indirect benefits to society at large, e.g., in the context of the United Nations Sustainable Development Goals. Such societal benefits should also be assessed.In this deliverable, we address the identification of Key Performance Indicators (KPIs) and Key Value Indicators (KVIs) that will be used to assess both types of impacts –performance impact and societal impact, respectively—generated by the techniques proposed in CENTRIC. We first review the state-of-art on KPI and KVI definitions in relevant bodies and projects, then identify and define those that are relevant for CENTRIC activities and, to finalize, we link each of the technologies developed in the project to the KPIs and KVIs that are specifically relevant for them. The resulting set of KPIs and KVIs will be revised in deliverable D5.3, where in addition assessment methodologies for them will be proposed.

description: Economic incentives in Kazakhstan have been radically reshaped since the Soviet era ended in 1991. In the first phase of transition, the economy and agricultural sectors declined by 40-50%. Overall economic growth refused in 1996, and agriculture is likely to enter a recovery phase soon. The economy of Kazakhstan is undergoing rapid structural change, and agriculture is experiencing strong inter-sectoral competition. The change to market-oriented and commercially-driven agriculture has altered fundamentally the incentives faced by Kazakhstan's wheat farmers. They have reduced use of inputs sharply because of the need to pay market prices for fertilizer, fuel, and other inputs, while severely curtailing investment in machinery and their farms generally. There is considerable potential for productivity improvements and adoption of new technologies in the wheat production and marketing sectors. Farmers are likely to resume investment only slowly and are likely to adopt only those changes that are low cost and which are based on low-input methods of production. Assessed under 1998 conditions, these wheat growing methods are about 20% more competitive than the energy and input-intensive technologies of the Soviet era. Because of the new commercial pressures brought on by the opening of the Kazakhstan economy to global markets, the production methods of the Soviet era are no longer relevant to Kazakhstan's wheat farmers. A fundamental change of thinking and approach to the situation faced by farmers is required in research, extension, training and education. The new commercial circumstances of agriculture call for strategic analysis of the future for Kazakhstan's farming and of related policies, research and education. Action is required in these areas to reinvigorate Kazakhstan's agriculture, and programs should commence as soon as possible. The future for wheat in Kazakhstan is promising, providing there is concerted and strategic change in the mindsets, culture, and approaches of those working in and supporting the wheat industry.
Estimating entropy rate from censored symbolic time series: a test for time-irreversibility

description: In this work we introduce a method for estimating entropy rate and entropy production rate from finite symbolic time series. From the point of view of statistics, estimating entropy from a finite series can be interpreted as a problem of estimating parameters of a distribution with a censored or truncated sample. We use this point of view to give estimations of entropy rate and entropy production rate assuming that they are parameters of a (limit) distribution. The last statement is actually a consequence of the fact that the distribution of estimations obtained from recurrence-time statistics satisfy the central limit theorem. We test our method using time series coming from Markov chain models, discrete-time chaotic maps and real a DNA sequence from human genome.

description: This report is based on a study of the adoption and use of improved open-pollinated varieties and hybrids by small-scale farmers in the Department of Jutiapa, Guatemala. The majority of maize producers in Guatemala are small-scale subsistence farmers. Approximately 60% of the basic grains produced in the country are grown on farms that are too small to satisfy the basic nutritional needs of a typical family (5-6 persons). Increasing yields through the use of new technologies is seen as a critical step to ensuring adequate nutrition and increasing farmer income in the area. The study, conducted in June and July 1991, randomly surveyed 208 farmers in 18 municipalities of Jutiapa, apportioned according to the number of farms in each municipality. There was particular interest in assessing the impact of the Project of Generation and Transfer of Agricultural Technology and Seed Production (PROGETTAPS), which was launched in 1986 by the Instituto de Ciencia y Tecnología Agrícolas (ICTA) and the General Directorate of Agricultural Services (DIGESA) with the goal of increasing small-scale farmers access to improved seeds. Study findings reveal a complex pattern of seed use in Jutiapa. Although the farmers there use several types of local and improved maize seed, they seem to prefer and use the local variety known as Arriquin, as well as two improved materials: an open-pollinated variety (B-1) and a hybrid (H-5). The reported forms of acquisition and preferences indicate that most of the farmers use the same material from 1 to 3 sowing seasons. Yield gains and relative prices, two important factors determining the profitability of adoption of new varieties, are adequate. By changing from their local varieties to OPVs and hybrids, farmers most likely can expect yield increases ranging from 35% to 70%. The decision to use improved materials in part or all of the area cropped with maize is associated with a change in the maize cropping system. Results suggest that farmers that sow a plot of maize in monoculture tend to plant the entire area with improved seed, particularly with hybrids. Results also show that the size of the family, taken together with the cropping system, is an important factor influencing the probability of full adoption, particularly of hybrid materials. The findings indicate that the probability of using hybrid materials, either in part or all of a cropped area, increases with farm size. Importantly, results from the estimating model confirmed the trend observed at the aggregate level. PROGETTAPS had a significant impact on the adoption of OPVs in Jutiapa. Farmers that have experience with PROGETTAPS are more likely to adopt OPVs than those who do not have contact with it. Furthermore, the probability of adoption increases with the years of association farmers have had with the program.

description: We present a methodology combining neural networks with physical principle constraints in the form of partial differential equations (PDEs). The approach allows to train neural networks while respecting the PDEs as a strong constraint in the optimisation as apposed to making them part of the loss function. The resulting models are discretised in space by the finite element method (FEM). The method applies to both stationary and transient as well as linear/nonlinear PDEs. We describe implementation of the approach as an extension of the existing FEM framework FEniCS and its algorithmic differentiation tool dolfin-adjoint. Through series of examples we demonstrate capabilities of the approach to recover coefficients and missing PDE operators from observations. Further, the proposed method is compared with alternative methodologies, namely, physics informed neural networks and standard PDE-constrained optimisation. Finally, we demonstrate the method on a complex cardiac cell model problem using deep neural networks.
Killing symmetries of generalized Minkowski spaces. 2-Finite structure of space-time rotation groups

description: In this paper, we continue the study of the Killing symmetries of a N-dimensional generalized Minkowski space, i.e. a space endowed with a (in general non-diagonal) metric tensor, whose coefficients do depend on a set of non-metrical coordinates. We discuss here the finite structure of the space-time rotations in such spaces, by confining ourselves (without loss of generality) to the four-dimensional case. In particular, the results obtained are specialized to the case of a ''deformed'' Minkowski space $% \widetilde{M_{4}}$ (i.e. a pseudoeuclidean space with metric coefficients depending on energy), for which we derive the explicit general form of the finite rotations and boosts in different parametric bases.

description: People across society should be able to find and access research publications. However, increased open access does not necessarily mean that publications are easy to access. Outside academia people may have issues finding relevant research and locating open versions, for example due to lack of support, time, or access to search tools. Sustainability research is an area where this issue is particularly pertinent, as varied societal actors want to support sustainable transitions and practices.

In 2020 we published a bibliometric study comparing mappings of research connected to the SDGs (Armitage et al. 2020). Taking inspiration from portals such as swedishscience, this has been developed into a project focusing on societal access, where we are building a portal for Norwegian sustainability research (supported by the National Library of Norway; project website). During development we aim to address some of the issues highlighted by our bibliometric study, including:

Target-level mapping

More complete coverage of subjects and Norwegian-language publications by combining multiple data sources (such as Norway’s CRIS and National Infrastructure for Bibliometrics)

Implementing plural mappings, allowing users to view sets with different “relevance” to sustainability

Making it easier for users outside academia, with a focus on open science

In this poster presentation, we present our current solutions, including technical, user-input and communication aspects. Our goal is to inform about the project and get feedback and ideas from colleagues.
