description: Lexical collocations, which occur based on semantic relevance between lexicons, are of considerable importance in any language and in close relation to morphology and semantics. Nizami’s innovative and creative use of lexical collocations in syntagmatic axis makes his work different from other poets’ works. Due to the fact that recognizing the poet’s style and his way of applying the lexical collocations can elucidate his attitude towards life, the present study aims to assess the reasons underlying lexical collocations and etymology in the Nizami Ganjavi’s Khamseh. To achieve this goal, lexical collocations have been investigated on the basis of lexical relations, references to the Holy Quran and Persian mythology. Considering the criteria which have been used in evaluating the Khamseh’s lexical collocations, the reasons of most lexical collocations in other poets’ works can be perceived; therefore, the research’s findings can be helpful in different researches appraising the Persian collocations.Lexical collocations, which occur based on semantic relevance between lexicons, are of considerable importance in any language and in close relation to morphology and semantics.

description: A computational study of the growth of two-dimensional nematic spherulites in an isotropic phase was performed using a Landau-de Gennes type quadrupolar ensor order parameter model for the first-order isotropic/nematic transition of 5CB (pentyl-cyanobiphenyl). An energy balance, taking anisotropy into account, was derived and incorporated into the time-dependent model. Growth laws were determined for two different spherulite morphologies of the form tn, with and without the inclusion of thermal effects. Results show that incorporation of the thermal energy balance correctly predicts the transition of the growth law exponent from the volume driven regime (n=1) to the thermally limited regime (approaching n=0.5), agreeing well with experimental observations. An interfacial nemato-dynamic model is used to gain insight into the interactions that result in the progression of different spherulite growth regimes.

description: We present a combined experimental and theoretical analysis of the evolution of the near-band gap electronic and optical properties of Si$_{x}$Ge$_{1-x-y}$Sn$_{y}$ alloys lattice-matched to Ge and GaAs substrates. We perform photoreflectance (PR) and photoluminescence (PL) measurements on Si$_{x}$Ge$_{1-x-y}$Sn$_{y}$ epitaxial layers grown via chemical vapour deposition, for Si (Sn) compositions up to $x =$ 9.6% ($y =$ 2.5%). Our measurements indicate the presence of an indirect fundamental band gap, with PL observed $\approx$ 200-250 meV lower in energy than the direct $E_0$ transition identified by PR measurements. The measured PL is Ge-like, suggesting that the alloy conduction band (CB) edge is primarily derived from the Ge L-point CB minimum. Interpretation of the PR and PL measurements is supported by atomistic electronic structure calculations. Effective alloy band structures calculated via density functional theory confirm the presence of an indirect fundamental band gap, and reveal the origin of the observed inhomogeneous broadening of the measured optical spectra as being alloy-induced band hybridisation occurring close in energy to the CB edge. To analyze the evolution of the band gap, semi-empirical tight-binding (TB) calculations are employed to enable calculations for large supercell sizes. TB calculations reveal that the alloy CB edge is hybridized in nature, consisting at low Si and Sn compositions of an admixture of Ge L-, $Γ$- and X-point CB edge states, and confirm that the alloy CB edge retains primarily Ge L-point CB edge character. Our experimental measurements and theoretical calculations confirm a direct transition energy close to 1 eV in magnitude for Si and Sn compositions $x =$ 6.8 - 9.6% and $y =$ 1.6 - 2.2%.

title: Die Rolle nationalstaatlicher Interessen im europäischen Integrationsprozess der Westbalkan-Gruppe

description: Obwohl die Gruppe der „Westbalkan-Staaten“ Kroatien, Serbien, Mazedonien, Bosnien und Herzegowina, Albanien, Montenegro und Kosovo bereits im Jahr 2000 eine offizielle Beitrittsperspektive erhielt und sich im im Rahmen eines mehrstufigen Prozesses, an dessen Ende das finale Ziel der EU-Mitgliedschaft stehen soll, der EU annähert, schaffte es mit Kroatien bislang nur ein Staat aus der Gruppe, den Beitrittsprozess erfolgreich abzuschließen. Der Erweiterungsprozess der Staatengruppe gestaltete sich äußerst schwierig und war von vielen Rückschritten und Blockaden geprägt, die „Aufnahme- bzw. Integrationsfähigkeit“ der EU rückte in den Vordergrund der europäischen Debatte. Neben den Reformfortschritten der Westbalkan- Staaten schienen es insbesondere Kontroversen zwischen den Mitgliedstaaten und unterschiedliche mitgliedstaatliche Haltungen zu sein, die darüber entschieden, ob der Erweiterungsprozess voranschritt oder stagnierte. Im Rahmen dieser Untersuchung wird daher die Rolle mitgliedstaatlicher Interessen in der Erweiterungspolitik am Westbalkan untersucht. Die europäischen Mitgliedstaaten als Hauptakteure in der Erweiterungspolitik – sämtliche grundlegenden Entscheidungen, die den Erweiterungsprozess voranschreiten lassen, werden in den intergouvermentalen Gremien der EU getroffen – stehen dabei im Vordergrund. Aufbauend auf den theoretischen Prämissen des liberalen Intergouvermentalismus, der den Pro-zess der europäischen Integration vor allem als eine Folge intergouvermentaler Verhandlungen sieht, werden zwei zentrale Hypothesen – die Entstehung der Erweiterungspolitik als Folge von strategischen Aushandlungsprozessen der Mitgliedstaaten mit unterschiedlichen, innenpolitisch gebildeten Interessen sowie die Abhängigkeit der Erweiterungsprozesse von den Verhandlungen und Interessen der Mitgliedstaaten – einer näheren Untersuchung unterzogen. Die Rolle der EU-Mitgliedstaaten wird im Rahmen von drei Forschungsschritten untersucht, die sich einer umfassenden Analyse offizieller EU-Dokumente, einer komplementären Literatur- und Internetrecherche und der Auswertung quantitativer Daten bedienen, um die allgemeinen Grundlagen der Erweiterungspolitik am Westbalkan, mögliche Einflussfaktoren mitgliedstaatlicher Haltungen in der Erweiterungspolitik und konkrete einzelstaatliche Blockaden zu erfassen.

description: We show how the relation between Poisson brackets and symplectic forms can be extended to the case of inhomogeneous multivector fields and inhomogeneous differential forms (or pseudodifferential forms). In particular we arrive at a notion which is a generalization of a symplectic structure and gives rise to higher Poisson brackets. We also obtain a construction of Koszul type brackets in this setting.

description: A primordial black hole in the last stages of evaporation and located in the local neighborhood can produce a detectable signal in gamma ray and neutrino telescopes. We re-evaluate the expected gamma ray and neutrino fluxes from these transient point events and discuss the consequences for existing constraints. For gamma rays we improve the current bounds by a factor of few, while for neutrinos we obtain significantly different results than the existing literature. The capability and advantages of neutrino telescopes in the search for primordial black holes is discussed thoroughly. The correlations of gamma ray and neutrino energy and time profiles will be promoted as a powerful tool in identifying the primordial black holes, in case of detection.

Serotonin and exercise
Creators: name: Walsh, Michael Leonard
Publisher: name: University of British Columbia
Year: 2010

description: The effects of altering serotonin (5-HT) concentration on physical exercise were investigated in adult, male, hooded rats. The rats were trained to run on a treadmill at a speed of 40 m/min, then subjected to an exhaustive run. Serotonin levels were decreased by para-chlorophenylalanine (300 mg/kg; intragastric) and increased by 5-HT (50 ug; intraventricular). Rats with lowered 5-HT levels had a 30% increase in running time to exhaustion whereas their controls only had a 1% increase. Elevating 5-HT levels decreased running time 44% whereas appropiate controls had a 7% increase in running time. In some animals the effect of exercise on 5-HT levels in the cerebellum, medulla oblongata, hypothalamus, midbrain, striatum, hippocampus, and cortex were measured. When compared to yoked, shocked controls, exercised rats had no difference in the absolute levels of 5-HT except for a lesser amount in the hypothalamus. These results suggest that although exercise did not increase absolute 5-HT levels, changing resting levels of 5-HT can markedly alter subsequent running time to exhaustion.

In this paper, a parallel and deeply pipelined adaptive transmission-line modeling method with preconditioned conjugate gradient solver is designed in hardware and implemented on two Xilinx® XCVU37P FPGAs for the finite-element modeling of a three-phase transformer.
The finite-element analysis is a powerful method to obtain detailed insight into the operation of any electromagnetic equipment. However, the required computational power to solve a finite-element modeled power equipment is so heavy that most Newton-Raphson-method-based algorithms can barely achieve real-time simulation. The low latency and hardware parallelism of the field-programmable gate array (FPGA) provides a path forward. In this paper, a parallel and deeply pipelined adaptive transmission-line modeling method with preconditioned conjugate gradient solver is designed in hardware and implemented on two Xilinx® XCVU37P FPGAs for the finite-element modeling of a three-phase transformer. The accuracy of the transformer solver under both current-excited and voltage-excited conditions of the transformer was validated against the commercial FE simulation tool.

The contrast between the activities of the close environments of LIRGs and ULIRGs appears especially enhanced in the COSMOS field density peak at z~0.67, because LIRGs on this peak have a larger fraction of passive neighbours, while ULIRGs have as active close environments as those outside the large-scale structure. The differential environmental activity is related to the differences in the distributions of stellar mass ratios between LIRGs/ULIRGs and their close neighbours, as well as in the general local density fields.

26 September 2023 in Hamburg. Titled “Sign language data meets data

science – data science meets sign linguistics”, the workshop had the goal

of generating expertise for under-resourced sign languages (SLs) to extend

the scope of EASIER to more European SLs. The idea was to not only

support people who already work with SLs and train them in technological

approaches, but also to train people from data science, language technolo-

gies, etc. in the handling of SLs. Two parallel tracks introduced both groups

to relevant topics of the other area, followed by a joint track addressing lan-

guage technologies of the EASIER pipeline and ethical considerations.

description: Green's function in non-Hermitian systems has recently been revealed to be capable of directional amplification in some cases. The exact formulas for end-to-end Green's functions are significantly important for studies of both non-Hermitian systems and their applications. In this work, based on the Widom's formula, we derive exact formulas for the end-to-end Green's functions of single-band systems which depend on the roots of a simple algebraic equation. These exact formulas allow direct and accurate comparisons between theoretical results and experimentally measured quantities. In addition, we verify the prior established integral formula in the bulk region to agree with the result in our framework. We also find that the speed at which the Green's functions in the bulk region approach the prior established integral formula is not slower than an exponential decay as the system size increases. The correspondence between the signal amplification and the non-Hermitian skin effect is confirmed.

title: Die Gemeinsame Sicherheits- und Verteidigungspolitik im Lichte des klassischen Intergouvernementalismus
Creators: name: Handrich, Gregor
Publisher: name: Universität Innsbruck
Year: 2015

description: Das sicherheits- und verteidigungspolitische Handeln der Europäischen Union (EU) und ihrer direkten Vorgängerorganisationen gilt als besonders schwach vergemeinschaftetes Politikfeld. Der klassische Intergouvernementalismus nach Stanley Hoffmann könnte mit seiner staatszentrierten Haltung der Erklärung dieses Umstands dienen. Der vorliegende Beitrag hinterfragt dieses Erklärungspotential. Dazu werden zuerst zentrale Hypothesen zur Entwicklung der Sicherheits- und Verteidigungspolitik aus dem klassischen Intergouvernementalismus abgeleitet. In weiterer Folge werden diese anhand einer Zusammenfassung der Ereignisse hin zur Etablierung der Gemeinsamen Sicherheits- und Verteidigungspolitik (GSVP) der EU – unter besonderer Betrachtung der Einflussnahme der Mitgliedstaaten – überprüft. Die Untersuchung weist auf ein solides Erklärungspotential des klassischen Intergouvernementalismus in diesem Politikfeld hin: So bleiben die Nationalstaaten tatsächlich die zentralen Akteure in Sicherheits- und Verteidigungsangelegenheiten innerhalb der EU. Der Grund für die weitgehende Verhinderung einer Vergemeinschaftung liegt jedoch weniger im Charakter des Politikfelds als zentraler Bereich nationaler Souveränität (High Politics) als vielmehr in individuellen nationalen Interessenlagen.
description: The European Union’s (EU) and its direct predecessors’ action regarding security and defence matters is considered an especially weakly communitised policy field. With its state-centered stance, Stanley Hoffmann’s classical intergovernmentalism might serve to explain this situation. The contribution at hand brings this explanatory potential into question. To this end, central hypotheses concerning the evolution of security and defence policy are first deduced from classical intergovernmentalism. In further consequence, they are tested on the basis of a summary of the events leading to the establishment of the EU’s Common Security and Defence Policy (CSDP), with special consideration of the member states’ exertion of influence. The investigation points towards a solid explanatory potential of classical intergovernmentalism in this policy field: Indeed, nation states remain the central actors of security and defence matters within the EU. However, communitisation has not so much been largely prevented due to the policy field’s nature as a key area of national sovereignty (High Politics), but rather due to individual configurations of national interests.

description: Detecting community structure in real-world networks is a challenging problem. Recently, it has been shown that the resolution of methods based on optimizing a modularity measure or a corresponding energy is limited; communities with sizes below some threshold remain unresolved. One possibility to go around this problem is to vary the threshold by using a tuning parameter, and investigate the community structure at variable resolutions. Here, we analyze the resolution limit and multiresolution behavior for two different methods: a q-state Potts method proposed by Reichard and Bornholdt, and a recent multiresolution method by Arenas, Fernandez, and Gomez. These methods are studied analytically, and applied to three test networks using simulated annealing.

This paper proposes a comprehensive framework to assess the reliability of a power system considering the effect from various power converter uncertainties.
With the proliferation of renewable energy and power electronic converters in power systems, the reliability issue has raised more research attention than ever before. This paper proposes a comprehensive framework to assess the reliability of a power system considering the effect from various power converter uncertainties. For the converter stage, we formulate a reliability model for each power converter based on several semiconductor devices, for which ambient uncertainties and converter topologies are considered. For the system stage, we estimate system reliability indicators through a non-sequential Monte Carlo simulation and calculate their variances. Afterward, we leverage machine learning regression algorithms between two stages to establish a nonlinear reliability relation. Moreover, a variance-based sensitivity analysis (SA) is conducted to rank and identify the most influential converter uncertainties with respect to the variance of system EENS. Based on the SA conclusions, system operators can take proactive actions to mitigate the potential risk of the system.

description: Report Summary: In the first 12 years of Israel's statehood, its index of farm production increased from the 1948/49 base (100) to 489. But agriculture has rarely contributed more than about 12 percent of the national income or employed more than an average of 17 percent of the labor force. Most presently cultivable land is fully used. Neither unused national resources, opportunities for employment, nor marketing possibilities now indicate the potentials for an increase in the agricultural sector comparable to that of the 1948/49-1958/59 period. Improved production techniques have reduced the number of farmers required to sustain and reasonably increase farm production. Many older farm settlements cannot base themselves entirely on agriculture; industrial activity is becoming increasingly important as an adjunct to seasonal fluctuations in farm income. In some of the newer rural settlements on marginal lands, the role of agriculture is definitely subsidiary to that of industry. Israel's population doubled between 1949 and 1959; much is heard of the ingathering of an additional million in the next 10 years. To approach and maintain economic viability, Israel must increase the quantity and quality of the total national product for home consumption and export. But future growth of income from agriculture will have to come largely through better production techniques in presently developed areas and increased marketing efficiency.

description: Using reconstructed opacities, we construct solar models with low heavy-element abundance. Rotational mixing and enhanced diffusion of helium and heavy elements are used to reconcile the recently observed abundances with helioseismology. The sound speed and density of models where the relative and absolute diffusion coefficients for helium and heavy elements have been increased agree with seismically inferred values at better than the 0.005 and 0.02 fractional level respectively. However, the surface helium abundance of the enhanced diffusion model is too low. The low helium problem in the enhanced diffusion model can be solved to a great extent by rotational mixing. The surface helium and the convection zone depth of rotating model M04R3, which has a surface Z of 0.0154, agree with the seismic results at the levels of 1 $σ$ and 3 $σ$ respectively. M04R3 is almost as good as the standard model M98. Some discrepancies between the models constructed in accord with the new element abundances and seismic constraints can be solved individually, but it seems difficult to resolve them as a whole scenario.

description: High-temperature superconductors (HTS) are finding use as high - current wires for potential application in power devices. The dependence of their basal-plane critical current properties on orientation in a magnetic field can pose important design problems. Here we report material and operating parameter conditions where prototype HTS tape conductors exhibit critical current characteristics that are essentially field-orientation independent. The novel phenomenon is observed for specific magnetic field intensities that depend on the operating temperature, and in materials having strong flux pinning by extended nanoscale structures aligned roughly along the HTS crystalline c-axis. The effect can be described by a simple model for the field dependence of critical current density, generalized for anisotropic electronic response. This description may provide insight into means to fine-tune the material properties for nearly isotropic performance characteristics at a preferred field and temperature.

The measured branching fraction B(tau- -> K_S pi- nu_tau)=(0.404 +- 0.002(stat.) +- 0.013(syst.))% is consistent with the world average value and has better accuracy. An analysis of the K_S pi- invariant mass spectrum reveals contributions from the K*(892)- as well as other states. For the first time the K*(892)- mass and width have been measured in tau decay: M(K*(892)-)=(895.47 +- 0.20(stat.) +- 0.44(syst.) +- 0.59(mod.)) MeV/c2, Gamma(K*(892)-)=(46.2 +- 0.6(stat.) +- 1.0(syst.) +- 0.7(mod.)) MeV. The K*(892)- mass is significantly different from the current world average value.

description: We study the effect of the spin-orbit interaction on heavy holes confined in a double quantum dot in the presence of a magnetic field of arbitrary direction. Rich physics arise as the two hole states of different spin are not only coupled by the spin-orbit interaction but additionally by the effect of site-dependent anisotropic $g$ tensors. It is demonstrated that these effects may counteract in such a way as to cancel the coupling at certain detunings and tilting angles of the magnetic field. This feature may be used in singlet-triplet qubits to avoid leakage errors and implement an electrical spin-orbit switch, suggesting the possibility of task-tailored two-axes control. Additionally, we investigate systems with a strong spin-orbit interaction at weak magnetic fields. By exact diagonalization of the dominant Hamiltonian we find that the magnetic field may be chosen such that the qubit ground state is mixed only within the logical subspace for realistic system parameters, hence reducing leakage errors and providing reliable control over the qubit.

description: A two-qubit Heisenberg XYZ model with Dzyaloshinsky-Moriya (DM) and Kaplan-Shekhtman-Entin-Wohlman--Aharony (KSEA) interactions is considered at thermal equilibrium. Analytical formulas are derived for the local quantum uncertainty (LQU) and local quantum Fisher information (LQFI). Using the available expressions for the entropic quantum discord, we perform a comparative study of these measures of nonclassical correlation. Our analysis showed the following: all three measures of quantum correlation have similar qualitative and even quantitative behavior on temperature for different values of system parameters, there are regions in the parameter space which correspondent to a local increase of correlations with increasing temperature, and sudden changes in the behavior of quantum correlations occur at certain values of the interaction parameters.

description: This paper builds on a recent article co-authored by the present author, H. Hosni and F. Montagna. It is meant to contribute to the logical foundations of probability theory on many-valued events and, specifically, to a deeper understanding of the notion of strict coherence. In particular, we will make use of geometrical, measure-theoretical and logical methods to provide three characterizations of strict coherence on formulas of infinite-valued Łukasewicz logic
Quantifying Power System Operational and Infrastructural Resilience Under Extreme Conditions Within a Water-Energy Nexus Framework

This work presents definitions and metrics developed for quantifying the resilience of the electric power system while considering its interdependent operation with the water distribution system.
This work presents definitions and metrics developed for quantifying the resilience of the electric power system (EPS) while considering its interdependent operation with the water distribution system (WDS). These metrics are used within a novel formulation in order to determine EPS resilience during the coordinated real-time operation of the two systems where both the operational state and infrastructural configuration of the EPS is taken into account. Coordinated operation of the two systems involves simulations that account for the main dependencies of each system on the other (cooling water for thermoelectric generation and electric power for WDS pumps). The results for several test cases are used within this work to demonstrate how system resilience in the EPS is captured for simulations that emulate the critical conditions of long-term power outages (in the EPS) and severe drought (in the WDS).

description: We will discuss how stability and speed of normal zone propagation in YBCO-coated conductors is affected by interfacial resistance between the superconducting film and the stabilizer. Our numerical simulation has shown that the increased interfacial resistance substantially increases speed of normal zone propagation and decreases the stability margins. Optimization of the value of the resistance may lead to a better compromise between stability and quench protection requirements than what is found in currently manufactured coated conductors.

description: Studies of high redshift radio galaxies can shed light on the activity of active galactic nuclei (AGN) in massive elliptical galaxies, and on the assembly and evolution of galaxy clusters in the Universe. J1606+3124 has been tentatively identified as a radio galaxy at a redshift of 4.56, at an era of one-tenth of the current age of the Universe. Very long baseline interferometry (VLBI) images show a compact triple structure with a size of 68 parsecs. The radio properties of J1606+3124, including the edge-brightening morphology, peaked GHz radio spectrum, slow variability, and low jet speed, consistently indicate that it is a compact symmetric object (CSO). The radio source size and expansion rate of the hotspots suggest that J1606+3124 is a young (kinematic age of ~3600 years) radio source. Infrared observations reveal a gas- and dust-rich host galaxy environment, which may hinder the growth of the jet; however, the ultra-high jet power of J1606+3124 gives it an excellent chance to grow into a large-scale double-lobe radio galaxy. If its redshift and galaxy classification can be confirmed by further optical spectroscopic observations, J1606+3124 will be the highest redshift CSO galaxy known to date.

description: Let $M$ be a closed oriented manifold of dimension $n$ and $ω$ a closed 1-form on it. We discuss the question whether there exists a Riemannian metric for which $ω$ is co-closed. For closed 1-forms with nondegenerate zeros the question was answered completely by Calabi in 1969. The goal of this paper is to give an answer in the general case, i.e. not making any assumptions on the zero set of $ω$.

Unraveling the magnetic softness in Fe-Ni-B based nanocrystalline material by magnetic small-angle neutron scattering

description: We employ magnetic small-angle neutron scattering to investigate the magnetic interactions in $(Fe_{0.7}Ni_{0.3})_{86}B_{14}$ alloy, a HiB-NANOPERM-type soft magnetic nanocrystalline material, which exhibits an ultrafine microstructure with an average grain size below 10 nm. The neutron data reveal a significant spin-misalignment scattering, which is mainly related to the jump of the longitudinal magnetization at internal particle-matrix interfaces. The field dependence of the neutron data can be well described by the micromagnetic small-angle neutron scattering theory. In particular, the theory explains the 'clover-leaf-type' angular anisotropy observed in the purely magnetic neutron scattering cross section. The presented neutron-data analysis also provides access to the magnetic interaction parameters, such as the exchange-stiffness constant, which plays a crucial role towards the optimization of the magnetic softness of Fe-based nanocrystalline materials.

description: High-cadence optical observations of an H-alpha blue-wing bright point near solar AR NOAA 10794 are presented. The data were obtained with the Dunn Solar Telescope at the National Solar Observatory/Sacramento Peak using a newly developed camera system, the Rapid Dual Imager. Wavelet analysis is undertaken to search for intensity-related oscillatory signatures, and periodicities ranging from 15 to 370 s are found with significance levels exceeding 95%. During two separate microflaring events, oscillation sites surrounding the bright point are observed to twist. We relate the twisting of the oscillation sites to the twisting of physical flux tubes, thus giving rise to reconnection phenomena. We derive an average twist velocity of 8.1 km/s and detect a peak in the emitted flux between twist angles of 180 and 230 degrees.

description: A detailed analysis of muon-spin rotation ($μ$SR) spectra in the vortex state of type-II superconductors using different theoretical models is presented. Analytical approximations of the London and Ginzburg-Landau (GL) models, as well as an exact solution of the GL model were used. The limits of the validity of these models and the reliability to extract parameters such as the magnetic penetration depth $λ$ and the coherence length $ξ$ from the experimental $μ$SR spectra were investigated. The analysis of the simulated $μ$SR spectra showed that at high magnetic fields there is a strong correlation between obtained $λ$ and $ξ$ for any value of the Ginzburg-Landau parameter $κ= λ/ξ$. The smaller the applied magnetic field is, the smaller is the possibility to find the correct value of $ξ$. A simultaneous determination of $λ$ and $ξ$ without any restrictions is very problematic, independent of the model used to describe the vortex state. It was found that for extreme type-II superconductors and low magnetic fields, the fitted value of $λ$ is practically independent of $ξ$. The second-moment method frequently used to analyze $μ$SR spectra by means of a multi-component Gaussian fit, generally yields reliable values of $λ$ in the whole range of applied fields $ H_{c1} \ll H \lesssim H_{c2}$ ($H_{c1}$ and $H_{c2}$ are the first and second critical fields, respectively). These results are also relevant for the interpretation of small-angle neutron scattering (SANS) experiments of the vortex state in type-II superconductors.

description: Products of large-N conformal field theories coupled by multi-trace interactions in diverse dimensions are used to define quantum multi-gravity (multi-string theory) on a union of (asymptotically) AdS spaces. One-loop effects generate a small O(1/N) mass for some of the gravitons. The boundary gauge theory and the AdS/CFT correspondence are used as guiding principles to study and draw conclusions on some of the well known problems of massive gravity - classical instabilities and strong coupling effects. We find examples of stable multi-graviton theories where the usual strong coupling effects of the scalar mode of the graviton are suppressed. Our examples require a fine tuning of the boundary conditions in AdS. Without it, the spacetime background backreacts in order to erase the effects of the graviton mass.
