Lynx D4.4 Initial implementation and report of Data and Content Curation Services
Creators: name: Moreno-Schneider, Julián

Publisher: name: Zenodo
Year: 2019
Subjects: initial implementation, curation workflow manager

description: This report describes the initial implementation of the curation workflow manager (WM), which controls the workflows associated to every business use case (as defined in D4.1 [LynxD41]). This implementation is based on the definition provided in D4.2 [LynxD42] and D4.3 [LynxD43], in which we outlined four workflows: a common workflow, LKG population, and three use case specific workflows, namely Contract Analysis (OLS), Geothermal Project Analysis(DNVGL), and Labour Law Question Answering (CuatreCasas). The implementation of the curation workflow manager is based on the Camunda BPMN engine (https://camunda.com/products/bpmn-engine/), which allows the definition, implementation and execution of workflows inside the same tool. The main components of the curation workflow manager are: Workflow Manager Engine: it is responsible for converting workflows in tasks for the workers. Workers: they are responsible for the execution of tasks inside a workflow. Shared memory service: it is the service that both the Workflow Manager Engine and the Workers use to share large data objects. CAMUNDA API: it is a complete set of RESTful APIs useful to manage BPMN process definition [OMG2011], process instances and their history. PILOTS API: it is a component of the WM which is responsible for the access to manage and execute workflows. Camunda Modeler: it is a graphical user interface for defining workflows. At the moment of writing this deliverable we have already implemented three workflows of the four defined in D4.3 [LynxD43]. Legal Knowledge Graph Population Contract Analysis Geothermal Project Analysis This report also describes the implementation of the document manager(DCM), which is responsible for the storage of the Legal Knowledge Graph and the documents once they have been processed through the different workflows. The document manager is implemented using Trellis Linked Data Platform (LDP) (https://www.trellisldp.org/), so that it extends the idea of the Knowledge Graph (KG) including also the documents. By utilizing the flexibility of JSON-LD and the capabilities of an LDP, the DCM is the main building component of the Lynx Legal Knowledge Graph (LKG) and where the LKG lies. In the time left to finish the project, the following implementations will be completed: The workflow defined in D4.3 that is not yet implemented (Labour Law workflow). Some modifications in the curation workflow manager to support more efficient communication capabilities between the services.

description: This paper estimates an open-economy dynamic stochastic general equilibrium model with Bayesian techniques to analyse the macroeconomic effects of the European Central Bank’s (ECB’s) quantitative easing (QE) programme. Using data on government debt stocks and yields across maturities, we identify the parameter governing portfolio adjustment in the private sector. Shock decompositions suggest a positive contribution of ECB QE to annual euro area output growth and inflation in 2015-16 of up to 0.3 and 0.6 percentage points (pp) in the linearised version of the model. Allowing for an occasionally binding zero-bound constraint by using piecewise linear solution techniques raises the positive impact to up to 0.7 and 0.8 pp.
description: Nous estimons, par des techniques bayésiennes, un modèle d’équilibre général dynamique et stochastique en économie ouverte afin d’analyser les effets macroéconomiques du programme d’assouplissement quantitatif de la Banque centrale européenne (BCE). À partir des données portant sur l’encours des titres d’État et les taux de rendement pour la gamme des échéances, nous évaluons le paramètre qui détermine les ajustements de portefeuilles dans le secteur privé. Les décompositions de chocs effectuées montrent qu’en zone euro, les mesures d’assouplissement quantitatif de la BCE auraient entraîné, en 2015-2016, des effets positifs sur la croissance annuelle de la production et sur l’inflation à hauteur de 0,3 et 0,6 point de pourcentage dans la version linéarisée du modèle. Lorsque nous permettons que la contrainte de la borne du zéro soit occasionnellement active au moyen de techniques de linéarisation, l’incidence favorable se chiffre respectivement à 0,7 et 0,8 point de pourcentage.

description: We adapt the classical 3-decomposition of any 2-connected graph to the case of simple graphs (no loops or multiple edges). By analogy with the block-cutpoint tree of a connected graph, we deduce from this decomposition a bicolored tree tc(g) associated with any 2-connected graph g, whose white vertices are the 3-components of g (3-connected components or polygons) and whose black vertices are bonds linking together these 3-components, arising from separating pairs of vertices of g. Two fundamental relationships on graphs and networks follow from this construction. The first one is a dissymmetry theorem which leads to the expression of the class B=B(F) of 2-connected graphs, all of whose 3-connected components belong to a given class F of 3-connected graphs, in terms of various rootings of B. The second one is a functional equation which characterizes the corresponding class R=R(F) of two-pole networks all of whose 3-connected components are in F. All the rootings of B are then expressed in terms of F and R. There follow corresponding identities for all the associated series, in particular the edge index series. Numerous enumerative consequences are discussed.

description: Globulettes are small (radii $< 10$ kAU) dark dust clouds, seen against the background of bright nebulae. A majority of the objects have planetary mass. These objects may be a source of brown dwarfs and free floating planetary mass objects in the galaxy. In this paper we investigate how many globulettes could have formed in the Milky Way and how they could contribute to the total population of free floating planets. In order to do that we examine H-alpha images of 27 H~II regions. In these images, we find 778 globulettes. We find that a conservative value of the number of globulettes formed is $5.7\times 10^{10}$. If 10 \% of the globulettes form free floating planets then they have contributed with $5.7\times 10^{9}$ free floating planets in the Milky Way. A less conservative number of globulettes would mean that the globulettes could contribute $2.0\times 10^{10}$ free floating planets. Thus the globulettes could represent a non-negligible source of free floating planets in the Milky Way.

Anticipated Inflation and Unanticipated Price Change: A Test of the Price-Specie Flow Theory and the Phillips Curve

Subjects: subject: 150399 Business and Management not elsewhere classified
subject: FOS: Economics and business

description: The Phillips curve is widely accepted as the maintained theory of inflation. In the standard version of the theory current inflation depends on some measure of anticipated inflation and on the deviation of current output from full-employment output. Most recent studies of inflation report the continuing search for variables that increase the accuracy with which the theory predicts or forecasts. Recent surveys by Laidler and Parkin [15] and by Gordon [11] summarize these developments. An entirely different direction has been taken by Lucas [17, 19, 20] and Phelps [25]. These authors seek to provide a firm micro-foundation for the relation.

description: In 1984, G. Robin proved that the Riemann hypothesis is true if and only if the Robin inequality $σ(n)5040$, where $σ(n)$ is the sum of divisors function, and $γ$ is the Euler-Mascheroni constant. We exhibit a broad class of subsets $\cS$ of the natural numbers such that the Robin inequality holds for all but finitely many $n\in\cS$. As a special case, we determine the finitely many numbers of the form $n=a^2+b^2$ that do not satisfy the Robin inequality. In fact, we prove our assertions with the Nicolas inequality $n/ϕ(n)1$ our results for the Robin inequality follow at once.

Ground states of groupoid C*-algebras, phase transitions and arithmetic subalgebras for Hecke algebras

description: We consider the Hecke pair consisting of the group $P^+_K$ of affine transformations of a number field $K$ that preserve the orientation in every real embedding and the subgroup $P^+_O$ consisting of transformations with algebraic integer coefficients. The associated Hecke algebra $C^*(P^+_K,P^+_O)$ has a natural time evolution $σ$, and we describe the corresponding phase transition for KMS$_β$-states and for ground states. From work of Yalkinoglu and Neshveyev it is known that a Bost-Connes type system associated to $K$ has an essentially unique arithmetic subalgebra. When we import this subalgebra through the isomorphism of $C^*(P^+_K,P^+_O)$ to a corner in the Bost-Connes system established by Laca, Neshveyev and Trifkovic, we obtain an arithmetic subalgebra of $C^*(P^+_K,P^+_O)$ on which ground states exhibit the `fabulous' property with respect to an action of the Galois group $Gal(K^{ab}/H_+(K))$, where $H_+(K)$ is the narrow Hilbert class field. In order to characterize the ground states of the $C^*$-dynamical system $(C^*(P^+_K,P^+_O),σ)$, we obtain first a characterization of the ground states of a groupoid $C^*$-algebra, refining earlier work of Renault. This is independent from number theoretic considerations, and may be of interest by itself in other situations.

description: We use a new real-time database for Canada to study various output gap measures. This includes recently developed measures based on models incorporating many variables as inputs (and therefore requiring real-time data for many variables). We analyze output gap revisions and assess the usefulness of these gaps in forecasting total CPI inflation and three newly developed measures of core CPI inflation: CPI-median, CPI-trim and CPI-common. We also study whether labour-input gaps, projected output gaps, and simple combinations of output gaps can add useful information for forecasting inflation. We find that estimates of excess capacity (the extent to which the economy is below potential) were probably too large around the 2008-2009 recession, as they subsequently tended to be revised down. In addition, we find that, when forecasting CPI-common and CPI-trim, some gaps appear to provide information that reduces forecast errors when compared with models that use only lags of inflation. However, forecast improvements are rarely statistically significant. In addition, we find little evidence of the usefulness of output gaps for forecasting inflation measured by total CPI and CPI-median.
description: Nous utilisons une nouvelle base de données canadiennes en temps réel afin d’étudier diverses mesures de l’écart de production, dont des mesures élaborées récemment qui se fondent sur des modèles intégrant un grand nombre de variables (et nécessitant ainsi des données en temps réel pour un grand nombre de variables). Nous analysons les révisions de l’écart de production et évaluons l’utilité de ces écarts pour prévoir l’inflation mesurée par l’IPC global et l’évolution de trois nouveaux indicateurs de l’inflation fondamentale, en l’occurrence l’IPC-méd, l’IPC-tronq et l’IPC-comm. Nous cherchons aussi à savoir si les écarts du facteur travail, les écarts de production projetés et de simples combinaisons d’écarts de production peuvent éclairer utilement les prévisions d’inflation. Nous constatons que les estimations de la marge de capacités excédentaires (c.-à-d. le degré de sous-performance de l’économie en regard de son potentiel) étaient probablement trop élevées au moment de la récession de 2008-2009, étant donné qu’elles ont ensuite été généralement revues à la baisse. Par ailleurs, nous observons que, lorsqu’on projette l’IPC-comm et l’IPC-tronq, certains écarts paraissent fournir de l’information qui permet de réduire les erreurs de prévision par rapport aux modèles recourant uniquement à des valeurs retardées de l’inflation. Cependant, les améliorations obtenues dans la qualité des prévisions sont rarement significatives statistiquement. En outre, nous trouvons peu d’éléments qui montrent l’utilité des écarts de production pour prévoir l’inflation mesurée par l’IPC global et par l’IPC-méd.
Rigourous QCD Evaluation of Spectrum and Ground State Properties of Heavy Quarkonium Systems; with a Precision Determination of the bottom quark mass and of the eta-b mass

description: We present an evaluation of heavy quarkonium states (bottomium and charmonium) from first principles. We use tree-level QCD (including relativistic corrections) and the full one-loop potential; nonperturbative effects are taken into account at the leading order through the contribution of the gluon condensate . We use the values Lambda_QCD= 200 (+80/-60) MeV and = 0.042 +/- 0.020 GeV^4, but we trade the value of the quark mass by the masses of J/psi, Upsilon as input. We get good agreement in what is essentially a zero parameter evaluation for the masses of the 1S, 2S, 2P states of bottomium, the 1S state for charmonium, and the decay Upsilon --> e^+ e^-. As outstanding result we obtain the precise determination of the bottom quark mass (m_b) as well as an estimate of the hyperfine splitting M(Upsilon)-M(eta_b): m_b(m_b^2) = 4387 (+7/-2) (-3/+4) (+16/-32)(systematic) MeV, M(Upsilon)-M(eta_b) = 36 (+13/-7)(+3/-6) (+11/-5)(syst.) MeV, the first error due to that in Lambda_QCD, the second to that in (varied independently). For the c quark, we find m_c(m_c^2)= 1306 (+21/-34)(-6/+6) MeV (up to systematic errors).

description: The phenomenon of a Newton's pendulum with bobs of slightly varying lengths leads to a complex interplay of oscillatory motions that can be understood through the lens of physics. Each bob in such a pendulum system resonates at its unique natural frequency[5], determined by its length and mass. This variation in lengths results in distinct oscillation frequencies, which can be likened to the unique "string lengths" of local oscillators in various systems, such as cosmic regions or neural assemblies. The interaction of these oscillators can produce a coherent state, akin to a "leading note," along with its fractal overtones, creating a rich scenery of motion that is both mesmerizing and complex.

These slight differences yield unique natural frequencies that, when released, create a mesmerizing dance of braided, chiral and helical motions. The assembly exhibits its own “string length” (local curvature, energy density, or coupling strength), whose differences lead to phase variations that, through mutual interactions, produce a “leading note” (a fundamental coherent state) and its fractal overtones.[1]

I further contend that what I perceive as a wavefunction “collapse” upon observation is, in fact, a selective phase‐locking of this dual-phase superposition. By unifying cosmic structure formation, gravitational anomalies, and neural synchrony under RSM, I show how recursive fractal feedback and infinite adjacency yield a coherent, self-organizing tapestry of reality. Moreover, the interaction between different oscillators can lead to synchronization phenomena[4], where the oscillators begin to influence each other's motion. This is particularly relevant in the context of coupled systems, where the phase variations among oscillators can lead to emergent behaviors, such as the formation of coherent states.

description: Decision making is a challenging task in online recommender systems. The decision maker often needs to choose a contextual item at each step from a set of candidates. Contextual bandit algorithms have been successfully deployed to such applications, for the trade-off between exploration and exploitation and the state-of-art performance on minimizing online costs. However, the applicability of existing contextual bandit methods is limited by the over-simplified assumptions of the problem, such as assuming a simple form of the reward function or assuming a static environment where the states are not affected by previous actions. In this work, we put forward Policy Gradients for Contextual Recommendations (PGCR) to solve the problem without those unrealistic assumptions. It optimizes over a restricted class of policies where the marginal probability of choosing an item (in expectation of other items) has a simple closed form, and the gradient of the expected return over the policy in this class is in a succinct form. Moreover, PGCR leverages two useful heuristic techniques called Time-Dependent Greed and Actor-Dropout. The former ensures PGCR to be empirically greedy in the limit, and the latter addresses the trade-off between exploration and exploitation by using the policy network with Dropout as a Bayesian approximation. PGCR can solve the standard contextual bandits as well as its Markov Decision Process generalization. Therefore it can be applied to a wide range of realistic settings of recommendations, such as personalized advertising. We evaluate PGCR on toy datasets as well as a real-world dataset of personalized music recommendations. Experiments show that PGCR enables fast convergence and low regret, and outperforms both classic contextual-bandits and vanilla policy gradient methods.

description: To classify galaxies morphologically, we developed Galaxy Morphology Network, a convolutional neural network that classifies galaxies according to their bulge-to-total ratio. GaMorNet does not need a large training set of real data and can be applied to datasets with a range of signal-to-noise ratios and spatial resolutions. We first trained GaMorNet on simulations of galaxies with a bulge and a disk component and then used a technique called transfer learning to refine the already trained network using ∼25% of the real dataset to achieve misclassification rates of ≲5%. This has very important consequences, as the applicability of CNNs to future data-intensive surveys like LSST, WFIRST, and Euclid will depend on their ability to perform on multiple data-sets without the need for a large training set of real data. Using the GaMorNet classifications, we study the quenching of star formation in ∼100,000∼100,000 (z∼0z∼0) SDSS and ∼20,000 (z∼1) CANDELS galaxies. We find that bulge- and disk-dominated galaxies have completely different color-mass diagrams, in agreement with previous studies. For both SDSS and CANDELS galaxies, disk-dominated galaxies peak in the blue cloud, across a broad range of masses, consistent with slow exhaustion of star-forming gas with no rapid quenching. A small population of red disks is found at high mass (∼14% of disks at z∼0 and 2% of disks at z∼1). In contrast, bulge-dominated galaxies are mostly red, with much smaller numbers down towards the blue cloud, suggesting rapid quenching and fast evolution across the green valley.
Nonequilibrium Casimir-Polder Force between Nanoparticles and Graphene-Coated Silica Plate: Combined Effect of the Chemical Potential and Mass Gap

description: The Casimir-Polder force between spherical nanoparticles and a graphene-coated silica plate is investigated in situations out of thermal equilibrium, i.e., with broken time-reversal symmetry. The response of graphene coating to the electromagnetic field is described on the basis of first principles of quantum electrodynamics at nonzero temperature using the formalism of the polarization tensor in the framework of the Dirac model. The nonequilibrium Casimir-Polder force is calculated as a function of the mass-gap parameter, chemical potential of graphene and temperature of the graphene-coated plate, which can be both higher and lower than that of the environment. It is shown that the force value increases with increasing chemical potential, and this increase is more pronounced when the temperature of a graphene-coated plate is lower than that of the environment. The nonequilibrium force also increases with increasing temperature of the graphene-coated plate. This increase is larger when the plate is hotter than the environment. The effect is revealed that the combined impact of the chemical potential $μ$ and mass gap $Δ$ of graphene coating depends on the relationship between $Δ$ and 2$μ$. If $2μ>Δ$ the magnitude of the nonequilibrium force between nanoparticles and a cooled graphene-coated plate becomes much larger than for a graphene coating with $μ=0$. The physical reasons explaining this effect are elucidated. Possible applications of the obtained results are discussed.

description: This paper proposes an approach for a tool-agnostic and heterogeneous static code analysis toolchain in combination with an exchange format. This approach enhances both traceability and comparability of analysis results. State of the art toolchains support features for either test execution and build automation or traceability between tests, requirements and design information. Our approach combines all those features and extends traceability to the source code level, incorporating static code analysis. As part of our approach we introduce the "ASSUME Static Code Analysis tool exchange format" that facilitates the comparability of different static code analysis results. We demonstrate how this approach enhances the usability and efficiency of static code analysis in a development process. On the one hand, our approach enables the exchange of results and evaluations between static code analysis tools. On the other hand, it enables a complete traceability between requirements, designs, implementation, and the results of static code analysis. Within our approach we also propose an OSLC specification for static code analysis tools and an OSLC communication framework.

description: Recent data on the Gottfried sum and less recent ones on the pion-nucleon sigma term seem to disagree with naive parton-based expectations on the light (i.e., up, down and strange) quark content of the nucleon. We show that these discrepancies are resolved if nonperturbative contributions are included in the analysis of the data. These appear both in the computation of matrix elements of operators, and in their QCD scale dependence, and depend strongly on the quantum numbers of the given state.

description: We present the results of the application of a parameter space reduction methodology based on active subspaces (AS) to the hull hydrodynamic design problem. Several parametric deformations of an initial hull shape are considered to assess the influence of the shape parameters on the hull wave resistance. Such problem is relevant at the preliminary stages of the ship design, when several flow simulations are carried out by the engineers to establish a certain sensibility with respect to the parameters, which might result in a high number of time consuming hydrodynamic simulations. The main idea of this work is to employ the AS to identify possible lower dimensional structures in the parameter space. The complete pipeline involves the use of free form deformation to parametrize and deform the hull shape, the high fidelity solver based on unsteady potential flow theory with fully nonlinear free surface treatment directly interfaced with CAD, the use of dynamic mode decomposition to reconstruct the final steady state given only few snapshots of the simulation, and the reduction of the parameter space by AS, and shared subspace. Response surface method is used to minimize the total drag.

description: In the present paper, we study the braneworld scenarios in the presence of quintom dark energy coupled by gravity. The first-order formalism for the bent brane (for both de Sitter and anti-de Sitter geometry), leads us to discuss the shape invariance method in the bent brane systems. So, by using the fluctuations of metric and quintom fields we obtain the Schrodinger equation. Then we factorize the corresponding Hamiltonian in terms of multiplication of the first-order differential operators. These first-order operators lead us to obtain the energy spectrum with the help of shape invariance method.

description: Dynamic optimizing models with an IS-LM-type structure and slow price adjustments have been used for much recent monetary policy analysis, but usually with capital and investment treated as exogenous—a significant restriction. This paper demonstrates that investment decisions can be endogenized without undue complexity in such models and that these can be calibrated to provide reasonably realistic dynamic behavior. It is necessary, however, to include capital adjustment costs; models with no adjustment costs match cyclical data very poorly. Indeed, their match is considerably poorer than models with constant capital. The paper also finds that the preferred adjustment-cost specification is not close to quadratic.
Modelling spinal injury due to high-rate axial loading

Publisher: name: Imperial College London

description: This thesis focuses on the injuries of the lumbar spine due to high rate loading, using both cadaveric experiments and numerical modelling. Insurgent warfare has been characterised by the use of improvised explosive devices, often targeting military personnel inside vehicles. Those incidents are associated with spinal injuries of poor clinical outcome. Currently, spinal injury tolerance levels do not exist for the loading seen by blast casualties, and the biomechanics of the lumbar spine are not understood under impact loading. Experimental and numerical models were developed to investigate the response of single segments and bi-segments of the lumbar spine under impact loading conditions. A novel methodology for controlling posture and ensuring axial loading during experiments was developed. A single segment numerical model was developed using the finite element method; the load transmission through the segment and its stress distributions were analysed. A bi-segment numerical model was also developed and three different positions on the sagittal plane were simulated; flexed (10 ͦ), neutral (0 ͦ) and extended (-5 ͦ). Differences between postures were predicted and areas prone to injury were identified. The neutral posture was found to be the most severe for the same loading conditions. Injurious impact tests of bi-segment cadaveric specimens were performed for the aforementioned postures, and the neutral posture was found to sustain injuries associated with the poorest outcome compared to the flexed or extended specimens. The methodologies and technologies developed in this thesis can be used further to look into the injury biomechanics aspects of the lumbar spine and used as a test-bed for assessing current and develop new mitigation strategies. Immediate next steps would be to include the rest of the lumbar spine in the numerical model and then the pelvis so that the loading pathway from the seat through to the spine can be quantified.

description: Nodal line in parameter space, at which the energy gap closes up, can either be the boundary separating two topological quantum phases or two conventional phases. We study the topological feature of nodal line in parameter space via a dimerized Kitaev spin chain with staggered transverse field, which can be mapped onto the system of dimerized spinless fermions with p-wave superconductivity. The quantum phase boundaries are straight crossing degeneracy lines in 3D parameter space. We show that the nodal line acts as a vortex filament associated with a vector field, which is generated from the Zak phase of Bogoliubov-de Gennes band. We also investigate the topological invariant in Majorana fermion representation for open chain. The Majorana edge modes are not zero mode, but is still protected by energy gap. The exact mid-gap states of the Majorana lattice allows to obtain the corresponding Majorana probability distribution for whole 3D parameter space, which can establish a scalar field to identify the topological feature of the nodal lines. Furthermore, when we switch on a weak tunneling between two ends of the Majorana lattice, the topological invariants of the nodal lines can be obtained by the pumped Majorana probability from an adiabatic passage encircling the lines. Numerical simulations of quasi-adiabatic time evolution is performed in small system. We compute the current to monitor the transport of Majorana fermion, which exhibits evident character of topological pumping. Our results link the bulk topological invariant to the dynamical behavior of Majorana edge mode, extending the concept of bulk-edge correspondence.

description: Urban farming is a relatively new but rapidly developing area of urban research and practice. It combines not only environmental, but also social, economic and cultural aspects, becoming an effective tool for strengthening urban communities, maintaining food security and improving the ecological state of the urban environment. In global practice, urban farming has already proven its effectiveness in such megacities as New York, Tokyo, and London, and this trend is gradually gaining relevance for Ukrainian cities as well. Kharkiv, as one of the largest cities in Ukraine, has faced numerous challenges as a result of the war, which have made it necessary to find alternative approaches to ensuring food stability and integrating local communities. In an urbanized space that suffers from infrastructure damage and social challenges, urban farming is an innovative approach to addressing these issues. In addition, it provides unique opportunities for urban space development, community unification, and jobcreation

description: Оne of the biggest challenges of the millennium is global environmental pollution and the growing amount of waste. According to the UN and otherinternational organizations, this problem is recognized as one of the key threats to the Earth's ecosystems. Ukraine also faces serious challenges in thefield of waste management. In response, many countries, especially in the EU, have been introducing the concept of a circular economy over the pastdecades, which aims to reuse materials, reduce waste, and recycle. Although many countries have already moved to new waste managementmodels, such as extended producer responsibility (EPR) and recycling of household materials, the problem still remains. For example, the issue ofmicroplastics and garbage islands in the oceans has become more acute in the last decade. This indicates the need not only for individual changes inproduction and consumption, but also for a systematic approach to the development of new materials and technologies in the field of wastecollection, sorting and recycling
The Nature of Dark Energy and Constraints on Its Hypothetical Constituents from Force Measurements

description: This review considers the theoretical approaches to the understanding of dark energy which comprises approximately 68\% of the energy of our Universe and explains an acceleration in its expansion. Following a discussion of the main approach based on Einstein's equations with the cosmological term, the explanations of dark energy using the concept of some kind of scalar field are elucidated. These include the concept of a quintessence and modifications of the general theory of relativity by means of the scalar-tensor gravity exploiting the chameleon, symmetron, and environment-dependent dilaton fields and corresponding particles. After mentioning several laboratory experiments allowing to constrain the hypothetical scalar fields modeling the dark energy, special attention is devoted to the possibility of constraining the parameters of chameleon, symmetron, and environment-dependent dilaton fields from measuring the Casimir force. It is concluded that the parameters of each of these fields can be significantly strengthened in near future by using the next generation setups in preparation suitable for measuring the Casimir force at larger separations.

description: This work considers the so called warehouse problem, which is a prototypical problem of the trading activity of a merchant in a commodity market. It is known that the merchant's optimal trading policy for this problem has a basestock structure. The exiting proofs of this result hinge on marginal analysis, and may not be easily accessible to managers. This work provides an elementary derivation of the optimality of this structure relying almost exclusively on geometric arguments based on the notion of opportunity cost of a trade, a concept familiar to commodity merchants. Some aspects of managerial relevance associated with this structure are also discussed. It is hoped that the material presented in this work would be of interest to manages involved in the merchant management of commodity storage.
Weak Hyperon Decays: Quark Sea and SU(3) Symmetry Breaking

description: An explanation of the difference in the values of the apparent $f/d$ ratios for the S- and P- wave amplitudes of nonleptonic hyperon decays is proposed. The argument is formulated in the framework of the standard pole model with $(56,0^{+})$ ground-state and $(70,1^{-})$ excited baryons as intermediate states for the P- and S- waves respectively. Under the assumption that the dominant part of the deviation of $(f/d)_{P-wave}$ from $-1$ is due to large quark sea effects, $SU(3)$ symmetry breaking in energy denominators is shown to lead to a prediction for $(f/d)_{S-wave}$ which is in excellent agreement with experiment. This corroborates our previous unitarity calculations which indicated that the matrix elements $$ of the parity conserving weak Hamiltonian between the ground-state baryons are characterized by $f_{0}/d_{0} \approx -1.6$ or more. A brief discussion of the problem of the relative size of S- and P- wave amplitudes is given. Finally, implications for weak radiative hyperon decays are also discussed.
