description: Correlation functions of the composite field $T\bar{T}$ in the scaling Lee--Yang model are studied. Using the analytic expression for form factors of this operator recently proposed by Delfino and Niccoli \cite{DN}, we show numerically that the constraints on the $T\bar{T}$ expectation values obtained in \cite{AZ_VEVTT} and the additional requirement of asymptotic behavior lead to a perfect agreement with the ultraviolet asymptotic predicted by the conformal perturbation theory.

description: The mean king's problem with maximal mutually unbiased bases (MUB's) in general dimension d is investigated. It is shown that a solution of the problem exists if and only if the maximal number (d+1) of orthogonal Latin squares exists. This implies that there is no solution in d=6 or d=10 dimensions even if the maximal number of MUB's exists in these dimensions.

description: SCAN (Structural Clustering Algorithm for Networks) is a well-studied, widely used graph clustering algorithm. For large graphs, however, sequential SCAN variants are prohibitively slow, and parallel SCAN variants do not effectively share work among queries with different SCAN parameter settings. Since users of SCAN often explore many parameter settings to find good clusterings, it is worthwhile to precompute an index that speeds up queries. This paper presents a practical and provably efficient parallel index-based SCAN algorithm based on GS*-Index, a recent sequential algorithm. Our parallel algorithm improves upon the asymptotic work of the sequential algorithm by using integer sorting. It is also highly parallel, achieving logarithmic span (parallel time) for both index construction and clustering queries. Furthermore, we apply locality-sensitive hashing (LSH) to design a novel approximate SCAN algorithm and prove guarantees for its clustering behavior. We present an experimental evaluation of our algorithms on large real-world graphs. On a 48-core machine with two-way hyper-threading, our parallel index construction achieves 50--151$\times$ speedup over the construction of GS*-Index. In fact, even on a single thread, our index construction algorithm is faster than GS*-Index. Our parallel index query implementation achieves 5--32$\times$ speedup over GS*-Index queries across a range of SCAN parameter values, and our implementation is always faster than ppSCAN, a state-of-the-art parallel SCAN algorithm. Moreover, our experiments show that applying LSH results in faster index construction while maintaining good clustering quality.
The importance of piN → K Lambda process for the pole structure of the P11 partial wave T-matrix in the coupled channel pion-nucleon partial wave analysis

description: The pole structure of the P11 pion-nucleon partial wave is examined with the emphasis on the 1700 MeV energy domain. The mechanism of eliminating continuum ambiguities in pion-nucleon partial wave analyses by using the coupled channel formalism, presented elsewhere for the piN -> etaN channel, is applied for the piN -> K Lambda channel, with the aim to clarify the issue whether physical reality requires none (VPI/GWU), one (KH80, CMB, Kent, Pittsburgh/ANL, Giessen), or possibly two (Zagreb) poles of the partial wave T-matrix in the 1700 MeV range. The role of second inelastic channel for resolving the dilemma is demonstrated. It is pointed out that the experiments for the piN -> K Lambda and piN -> K Sigma channel, extremely important for the 1700 MeV range, are old and inconclusive so an urgent need for remeasuring that channel is stressed.

description: Traditionally, graph neural networks have been trained using a single observed graph. However, the observed graph represents only one possible realization. In many applications, the graph may encounter uncertainties, such as having erroneous or missing edges, as well as edge weights that provide little informative value. To address these challenges and capture additional information previously absent in the observed graph, we introduce latent variables to parameterize and generate multiple graphs. We obtain the maximum likelihood estimate of the network parameters in an Expectation-Maximization (EM) framework based on the multiple graphs. Specifically, we iteratively determine the distribution of the graphs using a Markov Chain Monte Carlo (MCMC) method, incorporating the principles of PAC-Bayesian theory. Numerical experiments demonstrate improvements in performance against baseline models on node classification for heterogeneous graphs and graph regression on chemistry datasets.

description: The EU protects EU growers of 15 kinds of fresh fruits and vegetables against international competition not only by the means of ad valorem tariffs of up to 20%, but also by the EU entry-price system (EPS), which is designed to restrict imports below the product-specific, politically designated entry price level. This study investigates the influence of the EPS on import prices of fruits and vegetables per product and country of origin. We utilise a unique data set comprising about 60,000 observations of daily synthetic import prices. We develop two indicators for the effectiveness of the EPS, which serve as variables in a cluster analysis identifying four classes differing in the relevance of the EPS. Results suggest that the relevance of the EPS is heterogeneous among products as well as countries of origin for most fruits and vegetables. Thus, an adequate assessment of the importance of the EPS requires not only a product-specific but also a country-specific analysis. Overall, our results indicate that the effectiveness of the EPS is highest for the import of artichokes, courgettes, cucumbers, lemons, plums and tomatoes. The influence of the EPS on apples, clementines and pears is significantly lower, and of least relevance for EU imports of apricots, mandarins, oranges, peaches and nectarines and table grapes. The EPS has the greatest effect on countries which neighbour the EU, whereas it is of minor importance for exports from far-away countries with the exception of China and South Africa.

description: We theoretically and numerically investigate a two-dimensional O(2) model where an order parameter is convected by shear flow. We show that a long-range phase order emerges in two dimensions as a result of anomalous suppression of phase fluctuations by the shear flow. Furthermore, we use the finite-size scaling theory to demonstrate that a phase transition to the long-range ordered state from the disordered state is second order. At a transition point far from equilibrium, the critical exponents turn out to be close to the mean-field value for equilibrium systems.

description: This paper considers genetically modified (GM) seed adoption decisions by farmers in a developing country under two alternative information regimes (with and without perfect information regarding production conditions) that allows the monopolist producer of GM seeds to either practice perfect discrimination or uniform pricing. Under each regime we analyze two scenarios: when the government can and cannot credibly commit to the announced form of welfare enhancing intervention in the domestic seed market. We show that the optimal policy under either information regime is to subsidize the price of conventional seeds. The optimal size of the conventional seed subsidy depends systematically, in turn, on the (i) marginal cost of GM and conventional seeds, (ii) price of chemical pesticides, (iii) degree to which GM seeds increase productivity, (iv) range of pest pressure among farmers, and (v) intensity of seed usage (GM and conventional). Nonetheless, our findings pinpoint time-inconsistency of government policies as a possible reason for sub-optimal coverage of GM seeds in developing countries.

Cardiac physiology and diving behaviour of double-crested cormorants (phalacrocorax auritus)
Creators: name: Enstipp, Manfred Roland
Publisher: name: University of British Columbia
Year: 2009

description: Heart rate and dive behaviour were monitored in adult double-crested cormorants during shallow and deep diving and after exposure to different breathing gas mixtures to investigate the role of intravascular chemoreceptors in cardiac and behavioural control during voluntary diving. A data logger was used to record heart rate and dive behaviour of cormorants diving within a shallow (1 m) and deep (13 m) dive tank. Pre-dive heart rate in both shallow and deep diving birds was about three times the resting heart rate, falling abruptly upon submersion to around 200 - 250 beats-min⁻¹. During shallow diving most birds showed a secondary drop in heart rate after 5 - 10 s into the dive to around the resting level. In contrast, during deep diving heart rate stabilised at the initial bradycardie level or decreased further only very slightly. Mean dive heart rate (± S.D.) was significantly lower during shallow diving (163.2 ± 14.0 beats-min"1) compared to deep diving (216.4 ± 7.7 beats-min"1), but in both cases was significantly above the resting value (137.9 ± 17.5 beats-min⁻¹). Exposure to a hyperoxic gas mixture before shallow diving significantly increased mean dive heart rate, while exposure to a hypoxic gas mixture in both the shallow and deep dive tank significantly reduced mean dive heart rate. In contrast, hypercapnic gas before diving had no significant effect on dive heart rate. These results suggest that the cardiac response to voluntary diving in double-crested cormorants is strongly influenced by changes in arterial oxygen tension (Pao₂) throughout the dive. Dive duration was unaffected by alterations in inspired gases, but surface interval duration decreased after hyperoxia and increased after hypoxia. The most efficient dive pattern (highest dive/pause ratio) was observed after hyperoxic exposure. To investigate the ontogeny of the cardiac response to voluntary diving, heart rate was also recorded from naive double-crested cormorant chicks. The cardiac response to first ever and subsequent voluntary submergence was similar to the response observed in adult cormorants. Heart rate was also monitored in a separate group of chicks in which the first exposure to water was during whole body forced submergence. Again, the observed response was similar to the adult forced submergence response, although the cardiac response of chicks to forced submergence was more extreme than in voluntary submergence. These results do not support the hypothesis that cormorants 'learn' the appropriate cardiac response to voluntary diving via habituation or conditioning of the ' classical dive response'.

description: We have used optical molecular spectroscopy to probe the many-body state of paired $^6$Li atoms near a broad Feshbach resonance. The optical probe projects pairs of atoms onto a vibrational level of an excited molecule. The rate of excitation enables a precise measurement of the closed-channel contribution to the paired state. This contribution is found to be quite small, supporting the concept of universality for the description of broad Feshbach resonances. The dynamics of the excitation provide clear evidence for pairing across the BEC-BCS crossover, and into the weakly interacting BCS regime.

By considering effective dimension five operators, the model predicts three light right-handed neutrinos, weakly mixed with the left-handed ones. We show also that the model is able to explain the LSND experiment and still be in agreement with solar and atmospheric data for neutrino oscillation.

description: Nested sampling is a simulation method for approximating marginal likelihoods proposed by Skilling (2006). We establish that nested sampling has an approximation error that vanishes at the standard Monte Carlo rate and that this error is asymptotically Gaussian. We show that the asymptotic variance of the nested sampling approximation typically grows linearly with the dimension of the parameter. We discuss the applicability and efficiency of nested sampling in realistic problems, and we compare it with two current methods for computing marginal likelihood. We propose an extension that avoids resorting to Markov chain Monte Carlo to obtain the simulated points.

description: This paper proposes a simple mathematical model of non-stationary and non-linear stochastic dynamics, which approximates a (globally) non-stationary and non-linear stochastic process by its locally (or \emph{"piecewise"}) stationary version. Profiting from the elegance and simplicity of both, the exact mathematical model referred to as the Ornstein-Uhlenbeck stochastic process (which is \emph{globally} stationary, Markov and Gaussian) and of the Lyapunov criterion associated with the stability of stationarity, we show that the proposed non-linear non-stationary model provides a natural extension of the Onsager-Machlup theory of equilibrium thermal fluctuations, to the realm of non-stationary, non-linear, and non-equilibrium processes. As an illustrative application, we then apply the extended non-equilibrium Onsager-Machlup theory, to the description of thermal fluctuations and irreversible relaxation processes in liquids, leading to the main exact equations employed to construct the \emph{non-equilibrium self-consistent generalized Langevin equation} (NE-SCGLE) theory of irreversible processes in liquids. This generic theory has demonstrated that the most intriguing and long-unsolved questions of the glass and the gel transitions are understood as a natural consequence of the second law of thermodynamics, enunciated in terms of the proposed piecewise stationary stochastic mathematical model.

description: We investigate how thermalization of gluons depends on the initial conditions assumed in ultrarelativistic heavy ion collisions at RHIC. The study is based on simulations employing the pQCD inspired parton cascade solving the Boltzmann equation for gluons. We consider independently produced minijets with $p_T > p_0=1.3 \sim 2.0$ GeV and a color glass condensate as possible initial conditions for the freed gluons. It turns out that full kinetic equilibrium is achieved slightly sooner in denser system and its timescale tends to saturate. Compared with the kinetic equilibration we find a stronger dependence of chemical equilibration on the initial conditions.

description: A new general-equilibrium model that links together rural-to-urban migration, the externality effect of the average level of human capital, and agglomeration economies shows that in developing countries, unrestricted rural-to-urban migration reduces the average income of both rural and urban dwellers in equilibrium. Various measures aimed at curtailing rural-to-urban migration by unskilled workers can lead to a Pareto improvement for both the urban and rural dwellers. In addition, the government can raise social welfare by reducing the migration of skilled workers to the city. Moreover, without a restriction on rural-to-urban migration, a government’s efforts to increase educational expenditure and thereby the number of skilled workers may not increase wage rates in the rural or urban areas.
Dust Growth and Settling in Protoplanetary Disks and Disk Spectral Energy Distributions. I. Laminar Disks

description: Dust growth and settling considerably affect the spectral energy distributions (SEDs) of protoplanetary disks. We investigated dust growth and settling in protoplanetary disks through numerical simulations to examine time-evolution of the disk optical thickness and SEDs. In the present paper, we considered laminar disks as a first step of a series of papers. As a result of dust growth and settling, a dust layer forms around the mid-plane of a gaseous disk. After the formation of the dust layer, small dust grains remain floating above the layer. Although the surface density of the floating small grains is much less than that of the dust layer, they govern the disk optical thickness and the emission. The floating small grains settle onto the dust layer in a long time scale compared with the formation of the dust layer. Rapid grain growth in the inner part of disks makes the radial distribution of the disk optical thickness less steep than that of the disk surface density. At t > 10^6yr, the optical thickness of the inner disk (> a few AU) almost vanishes, which may correspond to disk inner holes observed by Spitzer Space Telescope. Furthermore, we examined time-evolution of disk SEDs, using our numerical results and the two-layer model. The grain growth and settling decrease the magnitude of the SEDs especially. Our results indicate that grain growth and settling can explain the decrease in observed energy fluxes at millimeter/sub-millimeter wavelengths with time scales of 10^{6-7}yr without depletion of the disks.

description: We calculate the X-ray emission from the shocked fast wind blown by the central stars of planetary nebulae (PNs) and compare with observations. Using spherically symmetric self similar solutions, we calculate the flow structure and X-ray temperature for a fast wind slamming into a previously ejected slow wind. We find that the observed X-ray emission of six PNs can be accounted for by shocked wind segments that were expelled during the early PN phase, if the fast wind speed is moderate, v_2~400-600 km/sec, and the mass loss rate is a few times 10^{-7} Mo/year. We find, as proposed previously, that the morphology of the X-ray emission is in the form of a narrow ring inner to the optical bright part of the nebula. The bipolar X-ray morphology of several observed PNs, which indicates an important role of jets rather than a spherical fast wind, cannot be explained by the flow studied here.

description: This paper claims that the 2011 Italian referendum on nuclear power is taking shape as a clean laboratory for the measurement of one of the main aspects of the NIMBY (Not In My BackYard) issue. Since the citizens voted on the possibility for the government to set up new nuclear plants in well-known sites, we identify community preferences for their locations across Italian municipalities using the turnout rate. The Fukushima nuclear disaster that happened a few months before the referendum may have magnified negative attitudes toward nuclear power. Thus, taking into account regional and political features that may influence ideological aversion to nuclear power, we still find highly negative correlation between distance from nuclear sites and the turnout rate.

description: To achieve a better understanding of the diverse vulnerabilities of different social groups affected by the tsunami in December 2004 in Sri Lanka, a survey of 500 households in the Sri Lankan urban area of Galle has been conducted in cooperation with several institutes under the direction of the Institute of Environment and Human Security of the United Nations University (UNU-EHS). An important aim of the project is to analyze the determinants and effects of the migration decision at the household level to be able to support the development of appropriate prevention, assistance and resettlement policies. In this paper, we first develop a framework for analyzing the factors which have an impact on the household's decision to stay in or migrate from a tsunami-affected, risky area. By using a logistic regression analysis, this framework later provides a basis for the examination of the significance of each factor. In a second step, it is analyzed to what extent the same factors determine the probability of a household to receive financial, material, or psychological support. The results of the regression analysis indicate that especially households who have been affected by the tsunami to a great extent (e.g. by a high number of dead, missing or seriously injured household members), or households who have had bad experience with the sea already before the tsunami are more likely to migrate than others. Having relatives at a possible new place as well as having received financial and/or material support like tents or tools also both have a "pushing" impact on the household's decision to leave the area. This implies that most current support schemes encourage people to leave the high-risk areas. Factors which decrease a households' likelihood of migration are higher education, good access to information and the ownership of land and house, as well as support programs providing households with building material.

description: It is well established in the literature that foreign affiliates are subject to a series of governance and assimilation costs that deteriorate their performance. This is particularly relevant for firms which have been recently acquired by foreign investors. We employ the variation in civic capital across Italian provinces as an exogenous determinant of these governance costs. We derive the testable implication that there should be a clean evidence of a negative effect of foreign ownership on performance in areas where civic capital is low. As the level of local civic capital increases, this reduces the scope for internal transaction costs, and makes the governance of foreign affiliates easier, and their performance better.

We take this prediction to the data and find confirmation of our conceptual framework. Our analysis underlines the importance of the geographic heterogeneity of informal institutions when analyzing the effect of foreign ownership on firm performance.

description: We present a re-examination of mass spectral data obtained from the Pioneer Venus Large Probe Neutral Mass Spectrometer. Our interpretations of differing trace chemical species are suggestive of redox disequilibria in Venus' middle clouds. Assignments to the data (at 51.3 km) include phosphine, hydrogen sulfide, nitrous acid, nitric acid, carbon monoxide, hydrochloric acid, hydrogen cyanide, ethane, and potentially ammonia, chlorous acid, and several tentative PxOy species. All parent ions were predicated upon assignment of corresponding fragmentation products, isotopologues, and atomic species. The data reveal parent ions at varying oxidation states, implying the presence of reducing power in the clouds, and illuminating the potential for chemistries yet to be discovered. When considering the hypothetical habitability of Venus' clouds, the assignments reveal a potential signature of anaerobic phosphorus metabolism (phosphine), an electron donor for anoxygenic photosynthesis (nitrite), and major constituents of the nitrogen cycle (nitrate, nitrite, ammonia, and N2).

By focussing on Tanzania and Uganda, our comparative "most-similar-cases" research design ensures significant across- and within-case variation in violence against relatively similar background conditions. As a conceptual starting point the World Bank's Collier/Hoeffler model and theory are applied to both countries. It is argued that while the model's fit is relatively good, Collier/Hoeffler's main theoretical proposition that civil war onset is best predicted by the existence of opportunities (or financing availability through resource extortion) for rebellion does not correspond as well with the East African context. We propose a modified rational-choice framework focusing on micro-level economic motivations for state capture, which is argued to help explain cycles of violence in Uganda until the 1980s, as well as the "paradox of peace", i.e. the puzzle why East Africa has experienced sustained periods of absolute (Tanzania) and relative (Uganda nationally after 1986, Zanzibar since the 1970s) peace despite identity fragmentation. From this perspective, peace followed from successful elite strategies to co-opt opponents through a mixture of rent-sharing and non-violent authority, leading to identity-encompassing, hierarchical one-party structures able to overcome collective action problems of state capture and defence.

description: We developed a time-dependent density-matrix model to study photon-assisted (PA) electron transport in quantum cascade lasers. The Markovian equation of motion for the density matrix in the presence of an optical field is solved for an arbitrary field amplitude. Level-broadening terms emerge from microscopic Hamiltonians and supplant the need for empirical parameters that are often employed in related approaches. We show that, in quantum cascade lasers with diagonal design, photon resonances have a pronounced impact on electron dynamics around and above the lasing threshold, an effect that stems from the large spatial separation between the upper and lower lasing states. With the inclusion of PA tunneling, the calculated current density and output power are in good agreement with experiment.

description: We introduce a class of divergence-free vector fields on $\mathbb{R}^3$ obtained after a suitable localization of Beltrami fields. First, we use them as initial data to construct unique global smooth solutions of the three dimensional Navier-Stokes equations. The relevant fact here is that these initial data can be chosen to be large in any critical space for the Navier-Stokes problem, however they satisfy the nonlinear smallness assumption introduced in [10]. As a further application of the method, we use these vector fields to provide analytical example of vortex-reconnection for the three-dimensional Navier-Stokes equations on $\mathbb{R}^3$. To do so, we exploit the ideas developed in [14] but differently from this latter we cannot rely on the non-trivial homotopy of the three-dimensional torus. To overcome this obstacle we use a different topological invariant, i.e. the number of hyperbolic critical points of the vector field.

description: The Business Process Modeling Notation (BPMN) is a widely used standard notation for defining intra- and inter-organizational workflows. However, the informal description of the BPMN execution semantics leads to different interpretations of BPMN elements and difficulties in checking behavioral properties. In this article, we propose a formalization of the execution semantics of BPMN that, compared to existing approaches, covers more BPMN elements while also facilitating property checking. Our approach is based on a higher-order transformation from BPMN models to graph transformation systems. To show the capabilities of our approach, we implemented it as an open-source web-based tool.

description: Ethiopian montane rainforests are economically valuable repositories of biodiversity, especially of wild Coffea arabica populations, and they are vanishing at accelerating rates. Our research results confirm theory which explains biodiversity loss by diverging private and social net benefits from land conversion. Poor farmers basically live from hand-to-mouth and manage resources with very short term planning horizons. In such circumstances they cannot afford to carry the cost burden of conservation from which the broader national and global society benefits. Society, on the other hand, highly values the biodiversity of Ethiopia's montane rainforests, but has not managed to put mechanisms in place which enable to pay for the conservation of these values and conservation policies are in place but are not implemented. While it is economically rational for the farmer to convert forests into agricultural land and thereby improve his income (the financial incentive we refer to here), it is economically irrational for national and global society not to pay for conservation. The core reasons for such divergence is that institutions for conservation and sustainable use are not in place. We identify the most important ones and recommend changes for the Ethiopian case.

description: In this work, we present the program MAELAS to calculate magnetocrystalline anisotropy energy, anisotropic magnetostrictive coefficients and magnetoelastic constants in an automated way by Density Functional Theory calculations. The program is based on the length optimization of the unit cell proposed by Wu and Freeman to calculate the magnetostrictive coefficients for cubic crystals. In addition to cubic crystals, this method is also implemented and generalized for other types of crystals that may be of interest in the study of magnetostrictive materials. As a benchmark, some tests are shown for well-known magnetic materials.

description: Federated learning (FL) enables the collaboration of multiple deep learning models to learn from decentralized data archives (i.e., clients) without accessing data on clients. Although FL offers ample opportunities in knowledge discovery from distributed image archives, it is seldom considered in remote sensing (RS). In this paper, as a first time in RS, we present a comparative study of state-of-the-art FL algorithms for RS image classification problems. To this end, we initially provide a systematic review of the FL algorithms presented in the computer vision and machine learning communities. Then, we select several state-of-the-art FL algorithms based on their effectiveness with respect to training data heterogeneity across clients (known as non-IID data). After presenting an extensive overview of the selected algorithms, a theoretical comparison of the algorithms is conducted based on their: 1) local training complexity; 2) aggregation complexity; 3) learning efficiency; 4) communication cost; and 5) scalability in terms of number of clients. After the theoretical comparison, experimental analyses are presented to compare them under different decentralization scenarios. For the experimental analyses, we focus our attention on multi-label image classification problems in RS. Based on our comprehensive analyses, we finally derive a guideline for selecting suitable FL algorithms in RS. The code of this work is publicly available at https://git.tu-berlin.de/rsim/FL-RS.

description: The paper tackles the issue of social capital as observed in several ethnically bonded groups of agricultural rural communities in the mountainous regions of northern Philippines. In the first part of the paper, the social capital of indigenous farmers and traders are measured. Findings show that there are six components underlying social capital in the region: informal networks, core trust, institutional trust, poverty perception, common goals and life satisfaction. In addition, tests provide evidence that social capital in Benguet is influenced in varying degrees, by gender, education, religion, age and ethnicity. Comparing municipal social capital indices with the aggregate mean, overall social capital among agricultural communities in northern Philippines were found to be low. In the second part of the paper, the determinants influencing farmers' decision to do business with certain trader types was tested. Results show that farmers' decision-making was influenced by their inherent social capital; meaning, farmers with high social capital approach decision-making differently than farmers with low social capital. Empirical tests showed that farmers in the high social capital group were better-off than farmers in the low social capital group. Further analysis showed that the respondents' ethnic affiliation and level of institutional trust have the same influence among farmers in terms of selecting transacting partners.

description: Model-reduction techniques aim to reduce the computational complexity of simulating dynamical systems by applying a (Petrov-)Galerkin projection process that enforces the dynamics to evolve in a low-dimensional subspace of the original state space. Frequently, the resulting reduced-order model (ROM) violates intrinsic physical properties of the original full-order model (FOM) (e.g., global conservation, Lagrangian structure, state-variable bounds) because the projection process does not generally ensure preservation of these properties. However, in many applications, ensuring the ROM preserves such intrinsic properties can enable the ROM to retain physical meaning and lead to improved accuracy and stability properties. In this work, we present a general constrained-optimization formulation for projection-based model reduction that can be used as a template to enforce the ROM to satisfy specific properties on the kinematics and dynamics. We introduce constrained-optimization formulations at both the time-continuous (i.e., ODE) level, which leads to a constrained Galerkin projection, and at the time-discrete level, which leads to a least-squares Petrov-Galerkin (LSPG) projection, in the context of linear multistep schemes. We demonstrate the ability of the proposed formulations to equip ROMs with desired properties such as global energy conservation and bounds on the total variation.
