description: Singlet fission is a photoconversion process that generates a doubly excited, maximally spin entangled pair state. This state has applications to quantum information and computing that are only beginning to be realized. In this article, we construct and analyze a spin-exciton hamiltonian to describe the dynamics of the two-triplet state. We find the selection rules that connect the doubly excited, spin-singlet state to the manifold of quintet states and comment on the mechanism and conditions for the transition into formally independent triplets. For adjacent dimers that are oriented and immobilized in an inert host, singlet fission can be strongly state-selective. We make predictions for electron paramagnetic resonance experiments and re-assign some transitions from recent literature. Our results give conditions for which magnetic resonance pulses can drive transitions between optically polarized magnetic sublevels of the two-exciton states, making it possible to realize quantum gates at room temperature in these systems.

Sulphate toxicity to freshwater organisms and molybdenum toxicity to rainbow trout (Oncorhynchus mykiss)
Creators: name: Davies, Trevor Dickson
Publisher: name: University of British Columbia
Year: 2009

description: The current "Ambient Water Quality Guidelines for Sulphate (Singleton 2000)" is largely based on studies that have serious flaws that do not accurately assess the toxicity of sulphate. Replication of the principle studies used in the current sulphate guideline rational indicates that the original studies were either flawed in their methodology or the results were misinterpreted. The authors used organisms representing a number of trophic levels and examined sulphate toxicity to the amphipod Hyalella azteca (Davies 2002a), the cladoceran Daphnia magna (Davies 2002b), the stripped bass (Morone saxatilus) (Davies 2002c) and the aquatic moss (Fontinalis antipyretica) (Davies 2002d). These replicated studies can be found in the appendices of this report. These studies, as well as others in the literature, indicate that organisms exhibit reduced toxicity from sodium sulphate exposure in waters of increasing hardness and more specifically, waters with increasing calcium content. The incorporation of these new studies into the available literature indicate that in consideration of the relatively low toxicity of sulphate, the current guideline is overly conservative and proposes unnecessarily strict discharge limits. Therefore, a new guideline, taking into consideration the water hardness of the receiving waters is proposed. In waters of hardness (as CaCO3) of less than 50 mg/L, a maximum allowable discharge that should be sufficient in the protection of ecosystem integrity is proposed at 200 mg/L sulphate. In the range of hardness of 50 to 100 mg/L and in waters of over 100 mg/L hardness, allowable discharge limits of 300 and 400 mg/L sulphate respectfully are proposed. Two experiments examining the toxicity of molybdenum to rainbow trout (Oncorhynchus mykiss) indicate that the results of an earlier study which reported a 29 day LC50 to be 0.79 mg/L molybdenum (Birge et al. 1980) highly exaggerated the toxicity of molybdenum (Davies 2002e). An experiment mimicking the experimental conditions of Birge et al. (1980) study did not cause sufficient mortality to calculate an LC50 up to molybdenum concentrations of 400 mg/L. A second study, which used standard methodology, also did not cause sufficient mortality up to concentrations of 1500 mg/L molybdenum to calculate an LC50.

description: The Spitzer Infrared Nearby Galaxies Survey (SINGS) is carrying out a comprehensive multi-wavelength survey on a sample of 75 nearby galaxies. The 1-850um spectral energy distributions are presented using broadband imaging data from Spitzer, 2MASS, ISO, IRAS, and SCUBA. The infrared colors derived from the globally-integrated Spitzer data are generally consistent with the previous generation of models that were developed based on global data for normal star-forming galaxies, though significant deviations are observed. Spitzer's excellent sensitivity and resolution also allow a detailed investigation of the infrared spectral energy distributions for various locations within the three large, nearby galaxies NGC3031 (M81), NGC5194 (M51), and NGC7331. Strong correlations exist between the local star formation rate and the infrared colors f_nu(70um)/f_nu(160um) and f_nu(24um)/f_nu(160um), suggesting that the 24 and 70um emission are useful tracers of the local star formation activity level. Preliminary evidence indicates that variations in the 24um emission, and not variations in the emission from polycyclic aromatic hydrocarbons at 8um, drive the variations in the f_nu(8.0um)/f_nu(24um) colors within NGC3031, NGC5194, and NGC7331. If the galaxy-to-galaxy variations in spectral energy distributions seen in our sample are representative of the range present at high redshift then extrapolations of total infrared luminosities and star formation rates from the observed 24um flux will be uncertain at the factor-of-five level (total range). The corresponding uncertainties using the redshifted 8.0um flux (e.g. observed 24um flux for a z=2 source) are factors of 10-20. Considerable caution should be used when interpreting such extrapolated infrared luminosities.

Three Levels of Modeling: Static (Structure/Trajectories of Flow), Dynamic (Events) and Behavioral (Chronology of Events)

Publisher: name: arXiv
Year: 2020
Subjects: subject: Software Engineering (cs.SE)

description: Constructing a conceptual model as an abstract representation of a portion of the real world involves capturing the (1) static (things/objects and trajectories of flow), (2) the dynamic (event identification), and (3) the behavior (e.g., acceptable chronology of events) of the modeled system. This paper focuses on examining the behavior notion in modeling and current works in the behavior space to illustrate that the problem of behavior and its related concepts in modeling lacks a clear-cut systematic basis. The purpose is to advance the understanding of system behavior to avoid ambiguity-related problems in system specification. It is proposed to base the notion of behavior on a new conceptual model, called the thinging machine, which is a tool for modeling that establishes three levels of representation: (1) a static structural description that is constructed upon the flow of things in five generic operations (activities; i.e., create, process, release, transfer and receive); (2) a dynamic representation that identifies hierarchies of events based on five generic events; and (3) a chronology of events. This is shown through examples that support the thinging machine as a new methodology suitable for all three levels of specification.

description: We investigate the end of the inflationary period in the recently proposed scenario of locked inflation, and consider various constraints arising from density perturbations, loop corrections, parametric resonance and defect formation. We show that in a scenario where there is one long period of locked inflation, it is not possible to satisfy all of these constraints without having a period of saddle inflation afterwards, which would wipe out all observable signatures. On the other hand, if one does not insist on satisfying the loop correction constraint, saddle inflation can be avoided, but then inflation must have ended through parametric resonance.

description: This report relates to a comparative study of the production cost of eggs in 2004 in some EU countries and Brazil and the USA. This was supplemented by a review of the prospects up until 2012. An insight was obtained into the national developments in animal welfare, environmental measures, and food safety. It was concluded that the production cost of eggs in the EU will further increase and as a result the difference in production cost with the non-EU countries will further increase. In the EU, Dutch and German layer farmers are confronted with additional animal-welfare and environmental regulations as compared to their counterparts in France, Spain and Poland. In dit rapport worden de kostprijzen van eieren in 2004 van verschillende EU-landen vergeleken met Brazilië en de Verenigde Staten. Voor alle genoemde landen is een doorkijk gemaakt naar het jaar 2012. Per land zijn de ontwikkelingen op het gebied van dierenwelzijn, milieu en voedselveiligheid in kaart gebracht. Geconcludeerd wordt dat in de EUlanden de komende jaren de kostprijs voor eieren zal stijgen, waardoor het verschil met de niet-EU-landen verder toeneemt. Binnen de EU hebben de leghennenhouders in Nederland en Duitsland te maken met extra regelgeving op het gebied van dierenwelzijn en milieu in vergelijking met Frankrijk, Spanje en Polen.

description: Aquatic macrophytes were monitored in 24 river sites from mountain and semi-mountainriver types during the main vegetation season in 2020. As basic community metrics species composition (both submerged and at different levels on the banks, where they are occasionally flooded) and abundance were recorded. The applied Reference Index illustrated that the prevailing part of the sites were in high and good status (n=16). These locations were characterized by communities of aquatic mosses Platyhypnidium riparioides (Hedw.) Dixon, Fontinalis antipyretica Hedw., Cratoneuron filicinum (Hedw.), Leptodictyum riparium (Hedw.) Warnst. Three sites were assessed in moderate, 5 in poor status, where macrophyte communities were dominated by vascular plants Ceratophyllum demersum L. and Myriophyllum spicatum L. In conclusion, river sites in poor and bad status represented almost 25% of the studied sites and reflected strong anthropogenic pressure.

description: This report evaluates the effects of the Uruguay Round Agreement on Agriculture on EU's international agricultural trade position. EU's share in trade of total agricultural products has not changed over the period 1993-2003. Yet, the EU lost market shares in trade on cereals, sugar, and dairy and meat products. WTO commitments to reduce export support have contributed to these decreasing market shares. However, for some products demand developments have had greater impact on EU's market position than changes in trade policies due to the Uruguay Round Agreement on Agriculture.

description: We consider the $XYZ$ chain model of arbitrary spin $S$ in the high temperature region, with external magnetic field and single-ion anisotropy term. Our high-temperature expansion of the Helmholtz free energy is analytic in the parameters of the model for $S$, which may range from 1/2 to the classical limit of infinite spin ($S\to \infty$). Our expansion is carried out up to order $(J β)^5$. Our results agree with numerical results of the specific heat per site for $S=1/2$, obtained by the Bethe ansatz, with $h=0$ and D=0. Finally, we show that the magnetic susceptibility and magnetization of the quantum model can be well approximated by their classical analog in this region of temperature.

description: We have constructed the quasi-exactly-solvable two-mode bosonic realizations of su(2) and su(1, 1) algebra. We derive the relations leading to the conditions for quasi-exact solvability of two-boson Hamiltonians by determining a general procedure which maps the Schwinger representations of the su(2) and su(1, 1) algebras to the Gelfand-Dyson representations, respectively. This mapping allows us to study nonlinear quantum-optical systems in the framework of quasi-exact solvability. Our approach also leads to a simple construction of special functions of two variables which are the most appropriate functions to study quasi-probabilities in quantum optics.

If $|A\cup B|\le s$ for all $A\in\mathscr{A}, B\in \mathscr{B}$, then $\mathscr{A}$ and $\mathscr{B}$ are called cross $s$-union. Assuming that neither $\mathscr{A}$ nor $\mathscr{B}$ is empty, we prove several best possible bounds. In particular, we show that $|\mathscr{A}|+|\mathscr{B}|\le 1+\sum\limits_{0\le i\le s}{{n}\choose{i}}$. Supposing $n\ge 2s$ and $\mathscr{A},\mathscr{B}$ are antichains, we show that $|\mathscr{A}|+|\mathscr{B}|\le {{n}\choose{1}}+{{n}\choose{s-1}}$ unless $\mathscr{A}=\{\emptyset\}$ or $\mathscr{B}=\{\emptyset\}$. An analogous result for three families is established as well.

description: The influence of the nature of the boron precursor on the superconducting properties of polycrystalline MgB2 was studied. Critical current densities for the MgB2 made from high purity amorphous boron are at least a factor of three higher than typical values measured for standard MgB2 samples made from amorphous precursors. Two possible mechanisms are proposed to account for this difference. Samples made from crystalline boron powders have around an order of magnitude lower Jc compared to those made from amorphous precursors. X-ray, Tc and resistivity studies indicate that this is as a result of reduced current cross section due to the formation of Mg-B-O phases. The samples made from amorphous B contain far fewer Mg-B-O phases than crystalline B despite the fact that the amorphous B contains more B2O3. The different reactivity rates of the precursor powders accounts for this anomaly.

description: Several types of systems were put forward during the past decades to show that there exist {\it isospectral} systems which are {\it metrically} different. One important class consists of Laplace Beltrami operators for pairs of flat tori in $\mathbb{R}^n$ with $n\geq 4$. We propose that the spectral ambiguity can be resolved by comparing the nodal sequences (the numbers of nodal domains of eigenfunctions, arranged by increasing eigenvalues). In the case of isospectral flat tori in four dimensions - where a 4-parameters family of isospectral pairs is known- we provide heuristic arguments supported by numerical simulations to support the conjecture that the isospectrality is resolved by the nodal count. Thus - one can {\it count} the shape of a drum (if it is designed as a flat torus in four dimensions...).

Range of validity of transport equations

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: Transport equations can be derived from quantum field theory assuming a loss of information about the details of the initial state and a gradient expansion. While the latter can be systematically improved, the assumption about a memory loss is in general not controlled by a small expansion parameter. We determine the range of validity of transport equations for the example of a scalar $g^2 Φ^4$ theory. We solve the nonequilibrium time evolution using the three-loop 2PI effective action. The approximation includes off-shell and memory effects and assumes no gradient expansion. This is compared to transport equations to lowest order (LO) and beyond (NLO). We find that the earliest time for the validity of transport equations is set by the characteristic relaxation time scale $t_{\rm damp} = - 2ω/Σ^{\rm (eq)}_\varrho$, where $-Σ^{\rm (eq)}_\varrho/2$ denotes the on-shell imaginary-part of the self-energy. This time scale agrees with the characteristic time for partial memory loss, but is much shorter than thermal equilibration times. For times larger than about $t_{\rm damp}$ the gradient expansion to NLO is found to describe the ``full'' results rather well for $g^2 \lesssim 1$.

description: Recent observation of a "kink" in single-particle dispersion in photoemission experiments on cuprate superconductors has initiated a heated debate over the issue of a boson that mediates the pairing in cuprates. If the "kink" is indeed caused by interaction with a bosonic excitation, then there are two possible candidates: phonons and spin fluctuations. Here, the role of anti-ferromagnetic spin fluctuations in shaping the phase diagram of cuprate superconductors will be discussed. By using the local (momentum-integrated) dynamic spin susceptibility, recently measured in neutron scattering experiments to high energies, the electronic self-energies are calculated that agree in many aspects with those measured directly in angle-resolved photoemission (ARPES) and optical spectroscopies. The spin fluctuations therefore seem to play a role typically played by phonons in renormalizing single particles. The key question emerging from this picture is whether the coupling detected in ARPES reflects the mediating boson, i.e. whether the spin fluctuations may be responsible for superconducting pairing.

description: This project concerns an analysis of recent developments regarding decentralisation in national nature policy. We see decentralisation here as a transfer of tasks. But it is a multifaceted issue. As a 'decentralised single state', the Netherlands is traditionally characterised by co-government. We look at four policy dossiers here: 1) the Nature Conservancy Act, 2) the Impulse for Species Policy, 3) the Investment Budget for Rural Areas, 4) the Spatial Policy Document. An important finding is that a more definite link is required between the decentralised character of decision-making and the conditions for working in practice within the networks. Dit project betreft een analyse van recente ontwikkelingen rond de decentralisatie in het nationale natuurbeleid. Decentralisatie zien we hier als overdracht van taken. Maar het is een veelzijdig vraagstuk. Nederland als een 'gedecentraliseerde eenheidsstaat' heeft altijd te maken met uitvoering in medebewind. We behandelen hier vier beleidsdossiers: 1) de Natuurbeschermingswet, 2) de Impuls voor het Soortenbeleid, 3) het Investeringsbudget Landelijk Gebied, 4) de Nota Ruimte. Een belangrijke bevinding is dat een meer nadrukkelijke koppeling nodig is tussen het decentrale karakter van besluiten en de condities voor het werken in de praktijk binnen de netwerken.
Contextual Document Similarity for Content-based Literature Recommender Systems

description: To cope with the ever-growing information overload, an increasing number of digital libraries employ content-based recommender systems. These systems traditionally recommend related documents with the help of similarity measures. However, current document similarity measures simply distinguish between similar and dissimilar documents. This simplification is especially crucial for extensive documents, which cover various facets of a topic and are often found in digital libraries. Still, these similarity measures neglect to what facet the similarity relates. Therefore, the context of the similarity remains ill-defined. In this doctoral thesis, we explore contextual document similarity measures, i.e., methods that determine document similarity as a triple of two documents and the context of their similarity. The context is here a further specification of the similarity. For example, in the scientific domain, research papers can be similar with respect to their background, methodology, or findings. The measurement of similarity in regards to one or more given contexts will enhance recommender systems. Namely, users will be able to explore document collections by formulating queries in terms of documents and their contextual similarities. Thus, our research objective is the development and evaluation of a recommender system based on contextual similarity. The underlying techniques will apply established similarity measures and as well as neural approaches while utilizing semantic features obtained from links between documents and their text.

description: With huge improvement of digital connectivity (Wifi,3G,4G) and digital devices access to internet has reached in the remotest corners now a days. Rural people can easily access web or apps from PDAs, laptops, smartphones etc. This is an opportunity of the Government to reach to the citizen in large number, get their feedback, associate them in policy decision with e governance without deploying huge man, material or resourses. But the Government of multilingual countries face a lot of problem in successful implementation of Government to Citizen (G2C) and Citizen to Government (C2G) governance as the rural people tend and prefer to interact in their native languages. Presenting equal experience over web or app to different language group of speakers is a real challenge. In this research we have sorted out the problems faced by Indo Aryan speaking netizens which is in general also applicable to any language family groups or subgroups. Then we have tried to give probable solutions using Etymology. Etymology is used to correlate the words using their ROOT forms. In 5th century BC Panini wrote Astadhyayi where he depicted sutras or rules -- how a word is changed according to person,tense,gender,number etc. Later this book was followed in Western countries also to derive their grammar of comparatively new languages. We have trained our system for automatic root extraction from the surface level or morphed form of words using Panian Gramatical rules. We have tested our system over 10000 bengali Verbs and extracted the root form with 98% accuracy. We are now working to extend the program to successfully lemmatize any words of any language and correlate them by applying those rule sets in Artificial Neural Network.

description: This report looks into the extent to which regions are able to take anticipatory measures in implementing the Manure Policy in preparation for the Water Framework Directive, which will be implemented in 2009. Alongside a literature search, regional anticipation was investigated by means of interviews and a workshop. The general conclusion from the research is that regional anticipation is worth the effort of further elaboration. The parties involved have indicated both limitations and preferences, but no serious objections have been expressed. In dit rapport wordt onderzocht in hoeverre regio's met het uitvoeren van het Mestbeleid anticiperende maatregelen kunnen nemen om in te spelen op de Kaderrichtlijn Water, die in 2009 wordt ingevoerd. Naast literatuuronderzoek is op regionale anticipatie ingegaan in interviews en in een workshop.

description: We study the triton and three-nucleon force at lowest chiral order in pionless effective field theory both in the Hamiltonian and Euclidean nuclear lattice formalism. In the case of the Euclidean lattice formalism, we derive the exact few-body worldline amplitudes corresponding to the standard many-body lattice action. This will be useful for setting low-energy coefficients in future nuclear lattice simulations. We work in the Wigner SU(4)-symmetric limit where the S-wave scattering lengths {1}S{0} and {3}S{1} are equal. By comparing with continuum results, we demonstrate for the first time that the nuclear lattice formalism can be used to study few-body nucleon systems.

description: A model based on the strong-field and Born-Oppenheimer approximations qualitatively describes the distribution over vibrational states formed in a diatomic molecular ion following ionization of the neutral molecule by intense laser pulses. Good agreement is found with a recent experiment [X. Urbain et al., Phys. Rev. Lett. 92, 163004 (2004)]. In particular, the observed deviation from a Franck-Condon-like distribution is reproduced. Additionally, we demonstrate control of the vibrational distribution by a variation of the peak intensity or a change of frequency of the laser pulse.

description: We extend the notion of Dirac oscillator in two dimensions, to construct a set of potentials. These potentials becomes exactly and quasi-exactly solvable potentials of non-relativistic quantum mechanics when they are transformed into a Schrödinger-like equation. For the exactly solvable potentials, eigenvalues are calculated and eigenfunctions are given by confluent hypergeometric functions. It is shown that, our formulation also leads to the study of those potentials in the framework of the supersymmetric quantum mechanics.

description: The configuration model is one of the most successful models for generating uncorrelated random networks. We analyze its behavior when the expected degree sequence follows a power law with exponent smaller than two. In this situation, the resulting network can be viewed as a weighted network with non trivial correlations between strength and degree. Our results are tested against large scale numerical simulations, finding excellent agreement.

Suppressing Super-Horizon Curvature Perturbations?

description: We consider the possibility of suppressing superhorizon curvature perturbations after the end of the ordinary slow-roll inflationary stage. This is the opposite of the curvaton limit. We assume that large curvature perturbations are created by the inflaton and investigate if they can be diluted or suppressed by a second very homogeneous field which starts to dominate the energy density of the universe shortly after the end of inflation. We show explicit that the gravitational sourcing of inhomogeneities from the more inhomogeneous fluid to the more homogeneous fluid makes the suppression difficult if not impossible to achieve.

Casimir effect in Lorentz-violating scalar field theory: a local approach

description: We study the Casimir effect in the classical geometry of two parallel conductive plates, separated by a distance $L$, for a Lorentz-breaking extension of the scalar field theory. The Lorentz-violating part of the theory is characterized by the term $λ\left( u \cdot \partial ϕ\right )^{2}$, where the parameter $λ$ and the background four-vector $u ^μ$ codify Lorentz symmetry violation. We use Green's function techniques to study the local behavior of the vacuum stress-energy tensor in the region between the plates. Closed analytical expressions are obtained for the Casimir energy and pressure. We show that the energy density $\mathcal{E}_{C}$ (and hence the pressure) can be expressed in terms of the Lorentz-invariant energy density $\mathcal{E}_{0}$ as follows \begin{align} \mathcal{E}_{C} (L) = \sqrt{\frac{1-λu_{n} ^{2}}{1 + λu ^{2}}} \mathcal{E}_{0} (\tilde{L}) , \notag \end{align} where $\tilde{L} = L / \sqrt{1-λu_{n} ^{2}}$ is a rescaled plate-to-plate separation and $u_{n}$ is the component of $\vec{u}$ along the normal to the plates. As usual, divergences of the local Casimir energy do not contribute to the pressure.

description: The widespread distribution of Crustacea across every aquatic ecological niche on Earth is enabled due to their exoskeleton's versatile properties. Especially mineralization of the exoskeleton provides protection against diverse environmental threats. Thereby, the exoskeleton of some entomostracans is extremely phenotypically plastic, especially in response to predators. For instance, the freshwater zooplankton Daphnia forms conspicuous inducible morphological defenses, such as helmets, and can increase the stability of its exoskeleton, which renders them less vulnerable to predation. In this study, we reveal for the first time the chemical composition of the exoskeleton of Daphnia magna, using Raman spectroscopy, to be composed of α-chitin and proteins with embedded amorphous calcium carbonate (ACC). Furthermore, we reveal the exoskeleton's chemical changes associated with inducible defense mechanisms in the form of more substantial mineralization, which is probably correlated with enhanced carapace stability. We, therefore, highlight the importance of calcium-biominerals for inducible morphological defenses in Daphnia.
