description: Emerging applications of machine learning in numerous areas involve continuous gathering of and learning from streams of data. Real-time incorporation of streaming data into the learned models is essential for improved inference in these applications. Further, these applications often involve data that are either inherently gathered at geographically distributed entities or that are intentionally distributed across multiple machines for memory, computational, and/or privacy reasons. Training of models in this distributed, streaming setting requires solving stochastic optimization problems in a collaborative manner over communication links between the physical entities. When the streaming data rate is high compared to the processing capabilities of compute nodes and/or the rate of the communications links, this poses a challenging question: how can one best leverage the incoming data for distributed training under constraints on computing capabilities and/or communications rate? A large body of research has emerged in recent decades to tackle this and related problems. This paper reviews recently developed methods that focus on large-scale distributed stochastic optimization in the compute- and bandwidth-limited regime, with an emphasis on convergence analysis that explicitly accounts for the mismatch between computation, communication and streaming rates. In particular, it focuses on methods that solve: (i) distributed stochastic convex problems, and (ii) distributed principal component analysis, which is a nonconvex problem with geometric structure that permits global convergence. For such methods, the paper discusses recent advances in terms of distributed algorithmic designs when faced with high-rate streaming data. Further, it reviews guarantees underlying these methods, which show there exist regimes in which systems can learn from distributed, streaming data at order-optimal rates.

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

description: The Fortran code SDECAY calculates the decay widths and branching ratios of all supersymmetric (SUSY) particles in the Minimal Supersymmetric Standard Model (MSSM), including higher order effects. The usual two-body decays of sfermions and gauginos as well as the three-body decay modes of charginos, neutralinos and gluinos are included. Furthermore, the three-body stop and sbottom decays and even the four-body stop decays are calculated. The important loop-induced decays, the QCD corrections to the two-body widths involving strongly interacting particles and the dominant electroweak effects to all processes are evaluated as well.

description: Fixation of ceramic prostheses by means of osteointegration implies use of porous structures in which bone tissues can grow. Such structures require total porosity values between 50 and 75 %, and pore size values between 100 and 500 μm. It is possible to manufacture scaffolds that comply with porosity requirements by means of 3D printing processes like Fused FilamentFabrication (FFF). However, such printing technology does not allow to directly select pore size and porosity value to be obtained. On the contrary, process variables such as layer height, nozzle diameter, infill, speed, etc. need to be selected beforeprinting. Main objective of the present work is to define a model that helps selecting appropriate values for printing variables inorder to obtain required porosity and pore size values. Such model will be applied to grid structures. In a first step, relationship was searched between pore size and three process variables: layer height, nozzle diameter and infill. In a further step, curves for pore size as a function of infill were searched for the three usual nozzle diameters employed for printing ceramics, 150, 250 and 410 μm. Finally, pore size and infill were determined for mean pore size of 300 μm. Results showed that the higher nozzlediameter, the lower infill should be.

description: In the period of 1995-2013 the Polish agro-food export exhibited a very dynamic growth. It has happened under free-floating exchange rate system, which is believed to help stimulate exports when the Polish currency depreciates. Using some econometric procedures we have found that the exchange rate fluctuations played very little role in shaping the Polish agro-food trade. A comparison of relative prices of selected agricultural and food products in Poland and in the EU suggests that adoption of euro at a conversion rate close to the recent market levels should not have a significant impact on the Polish agro-food export.
Studies on the dinoflagellate genome

Publisher: name: University of British Columbia

description: Dinoflagellates are unusual eukaryotes in many ways, but one of the most interesting features of this cell - its enormous genome - is not well studied because its sheer size is an obstacle to sequencing. Genome expansion can be the result of polyploidy, intron gain, mobile genetic elements, or large intergenic regions. I have studied organellar genome reduction in Kryptoperidinium foliaceum, intron composition in Heterocapsa triquetra and Karlodinium micrum, and surveyed genomic DNA from H. triquetra in order to get a better grasp on mechanisms of genome expansion in dinoflagellates. K. foliaceum has replaced its ancestral red algal plastid with a diatom plastid via tertiary endosymbiosis. Gene transfer from endosymbiont to host nucleus has likely occurred, but this endosymbiont is much less reduced than well-studied secondary endosymbiotic intermediates, the cryptophytes and chlorarachniophytes, where relict nuclear genomes (nucleomorphs) are retained. I sequenced the first protein-coding genes from the K. foliaceum endosymbiont and host nuclear genomes. I have characterised genes for nucleus-encoded cytosolic proteins, actin, alpha-tubulin, beta-tubulin, and HSP90, from both host and symbiont nuclei of K . foliaceum. Phylogenies show that the actin is diatom-derived, the beta-tubulin dinoflagellate-derived, while both diatom- and dinoflagellate-derived alpha-tubulin and HSP90 genes were found. The presence of these genes implies they are still functional and that the endosymbiont is at an earlier stage of genetic reduction than those of cryptophytes or chlorarachniophytes, Thirteen of 16 known dinoflagellate introns are non-canonical. I amplified and screened 63 K. micrum and H. triquetra genes, but found no introns. I report that introns are neither abundant in dinoflagellate genomes, nor have they played a major role in dinoflagellate genome expansion. I built a genomic DNA library for the dinoflagellate, H. triquetra, and sequenced 214 fragments (23 l,164bp). Main features of this library include imperfect complex repeats, retrotransposon domains, 53% G C content, few open reading frames (ORFs), and a lack of identifiable protein-coding regions. These results support mobile elements and repeats as major sources of DNA in expanded dinoflagellate genomes. The best explanation for the huge amounts of rion-coding DNA remains the idea that it functions as a structural scaffold and contributes to chromosomal organization.
On the sensitivity of the H-infinity norm of systems described by delay differential algebraic equations

description: We consider delay differential algebraic equations (DDAEs) to model interconnected systems with time-delays. The DDAE framework does not require any elimination techniques and can directly deal with any interconnection of systems and controllers with time-delays. In this framework, we analyze the properties of the H-infinity norm of systems described by delay differential algebraic equations. We show that the standard H-infinity norm may be sensitive to arbitrarily small delay perturbations. We introduce the strong H-infinity norm which is insensitive to small delay perturbations and describe its properties. We conclude that the strong H-infinity norm is more appropriate in any practical control application compared to the standard H-infinity norm for systems with time-delays whenever there are high-frequency paths in control loops.

description: We construct the grand partition function of the system of chiral fermions in a uniform magnetic field from Landau levels, through which all thermodynamic quantities can be obtained. Taking use of Abel-Plana formula, these thermodynamic quantities can be expanded as series with respect to a dimensionless variable $b=2eB/T^{2}$. We find that the series expansions of energy density, pressure, magnetization intensity and magnetic susceptibility contain a singular term with $\ln b^{2}$, while particle number density, entropy density and heat capacity are power series of $b^{2}$. The asymptotic behaviors of these thermodynamic quantities in extreme conditions are also discussed.

Pseudo-half-metalicity in the double perovskite Sr$_2$CrReO$_6$ from density-functional calculations

description: The electronic structure of the spintronic material Sr$_2$CrReO$_6$ is studied by means of full-potential linear muffin-tin orbital method. Scalar relativistic calculations predict Sr$_2$CrReO$_6$ to be half-metallic with a magnetic moment of 1 $μ_B$. When spin-orbit coupling is included, the half-metallic gap closes into a pseudo-gap, and an unquenched rhenium orbital moment appears, resulting in a significant increase of the total magnetic moment to 1.28 $μ_B$. This moment is significantly larger than the experimental moment of 0.9 $μ_B$. A possible explanation of this discrepancy is that the anti-site disorder in Sr$_2$CrReO$_6$ is significantly larger than hitherto assumed.

description: Organic food markets substantially rely on a reliable control system. To identify and isolate the effect of different factors potentially influencing the uniform implementation of organic controls, we apply a stepwise estimation of different logit models. Using control data of German farms from five important control bodies we identify, first, risk factors for non-compliance of farms, second, the impact of the control body as well as, third, the potential impact of governmental institutions which are in charge for the implementation of the control system. The results indicate a need for a more harmonized implementation of the German organic control system.

description: Urban water management (UWM) issues shape and frame the future of millions of people living in rapidly expanding cities. Yet understandings of the politics of institutional culture and responses to crisis in water management in rapidly growing conurbations have been conceptually and empirically limited. This study examines UWM in the context of crisis by approaching the issue of UWM through an understanding of the politics of institutional culture. In doing so, the thesis argues that UWM in growing cities amidst climate uncertainty and rapid urbanisation is crisis-prone and remains a product of complex institutional cultures, and state actions that together challenge approaches to sustainable urban water management.
Creating single time-bin entangled photon pairs

Year: 2004
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: When a single emitter is excited by two phase-coherent pulses with a time delay, each of the pulses can lead to the emission of a photon pair, thus creating a ``time-bin entangled'' state. Double pair emission can be avoided by initially preparing the emitter in a metastable state. We show how photons from separate emissions can be made indistinguishable, permitting their use for multi-photon interference. Possible realizations are discussed. The method might also allow the direct creation of n-photon entangled states (n>2).

description: This study extends a prior investigation of limit shapes for partitions of integers, which was based on analysis of sums of geometric random variables. Here we compute limit shapes for grand canonical Gibbs ensembles of partitions of sets, which lead to the sums of Poisson random variables. Under mild monotonicity assumptions, we study all possible scenarios arising from different asymptotic behaviors of the energy, and also compute local limit shape profiles for cases in which the limit shape is a step function.

description: In the high-dimensional data setting, the sample covariance matrix is singular. In order to get a numerically stable and positive definite modification of the sample covariance matrix in the high-dimensional data setting, in this paper we consider the condition number constrained covariance matrix approximation problem and present its explicit solution with respect to the Frobenius norm. The condition number constraint guarantees the numerical stability and positive definiteness of the approximation form simultaneously. By exploiting the special structure of the data matrix in the high-dimensional data setting, we also propose some new algorithms based on efficient matrix decomposition techniques. Numerical experiments are also given to show the computational efficiency of the proposed algorithms.

We give a necessary and sufficient condition for such manifolds to be diffeomorphic to a cusp cross-section of an arithmetic X-hyperbolic (n+1)-orbifold. A principal tool in the proof of this classification theorem is a subgroup separability result which may be of independent interest.

description: Resulting from the reduction of tariffs, the significance of and the interest in the impact of Non-Tariff Measures on agricultural trade has increased. The aim of this paper is to analyze the relationship between NTMs and tariffs in Mediterranean (MED) countries. A product-by-product taxonomy combining the two measures was created, and later a statistical analysis between them was applied. We identified an overall relatively low level of protection. Our findings indicate that there are dynamic substitution statistical relationships between NTM and tariffs, although with big variations across goods and countries, which gives room to ongoing efforts of harmonization in the area of agricultural trade.

description: El escritor español setecentista Tadeo Felipe Cortés del Valle y Castillo nos ha dejado un corpus textual muy importante, hecho este que contrasta notablemente con la escasa atención que le ha prestado la crítica literaria. Tadeo Felipe escribió no poco y sobre muy diversos temas, movido, asimismo, por un aliento erudito muy característico de su siglo. Especial interés nos suscita aquí su amplia producción dramática, en la que se cuentan loas, entremeses, sainetes y alguna comedia. En estas páginas nos centramos en el análisis de sus loas, por constituir una de las partes más significativas del teatro de este autor, tanto desde el punto de vista cuantitativo como cualitativo. Estructuramos dicho análisis en cuatro bloques, a saber: estructura temática y función; personajes; estilo; y puesta en escena. En resumidas cuentas, con nuestro trabajo buscamos dignificar y poner en valor la figura de este erudito dramaturgo.

description: The publication of food inspection results is one of the innovative measures introduced that use both material and non-material motivation of food businesses to increase regulatory compliance. Disclosure is not a new instrument and has been implemented in, for instance, Denmark, Los Angeles or New York. In Germany, in the last decade a few food hygiene controls results were established (e.g., Berlin Pankow, North Rhine-Westphalia (NRW), Zwickau). In this paper, we present the first results of the empirical study we carried out in NRW at the beginning of 2014. The survey was carried out to answer the question of whether the disclosure of hygiene controls influences the motivation of food businesses to comply with rules.

description: We construct Locally Rotationally Symmetric (LRS) Bianchi type-I cosmological model in $f(R,T)$ theory of gravity when the source of gravitation is the mixture of barotropic fluid and dark energy (DE) by employing a time varying deceleration parameter (DP). We observe through the behavior of the state finder parameters $(r, s)$ that our model begins from the Einstein static era and goes to $Λ$CDM era. The EoS parameter($ω_d$) for DE varies from phantom ($ω-1$) phase which is consistent with the observational results. It is found that the discussed model can reproduce the current accelerating phase of expansion of the universe.

Sulla datazione dell’'Antiope' di Euripide

Year: 2020

description: The dating of Euripides’ Antiope to the beginning of the last decade of the fifth century by a well-known scholium on Aristophanes’ Frogs is considered unsure on account of the statistics for trimeter resolutions. In the light of the analysis in the paper of the composition of the main chorus and of the setting of Antiope, as well as of the lexical and thematic proximity between the most conspicuously ‘political’ fragments of the lost tragedy and certain passages from The Phoenician Women and Orestes, it is possible to pronounce in favour of the correctness of the scholium as transmitted and to narrow the time frame in which Antiope would have been performed to a shorter span contained within the period between the staging of Andromeda and Euripides’ departure for Macedon. Sabina Castellaneta è ricercatrice a tempo determinato in Lingua e letteratura greca presso l’Università degli Studi di Bari. I suoi interessi di ricerca vertono principalmente sull’epica omerica, sulla lirica stesicorea e sulla tragedia euripidea, cui si aggiunge una specifica attenzione per l’ambito delle digital scholarly editions. In questi campi si inseriscono le sue pubblicazioni: la monografia Il seno svelato ad misericordiam (Bari 2013) e numerosi contributi su rivista e in atti di convegno.

description: We investigate the determinants of Russian regional wheat flows focusing on the role played by transport costs and regional infrastructure. We adapt the Anderson & van Wincoop (2003) gravity model to regional trade by considering a regional border effect and by assuming that trade costs are also determined by infrastructure variables. Our model identifies positive effects of the number and the average loading capacity of grain rail terminals in the region. This analysis reveals substantial effects of infrastructure on interregional wheat trade in Russia. Especially, the quality of infrastructure seems to have a strong effect, suggesting that improvements of infrastructure should focus on the improvements of the quality rather than the quantity of infrastructure.
Sofocle nei demi: problemi metodologici e interpretativi nello studio delle iscrizioni drammatiche sulle repliche della tragedia
Creators: name: Sidoti, Nello
Publisher: name: Frammenti sulla Scena (online)

description: In the last decades, a growing interest in the spread of theatre outside Athens put under the spotlight the notion of “reperformance”, i.e. the repeatability of originally Athenian performances in non-Athenian contexts. “Reperformance” is now a buzzword of Classical studies, but the analysis of the revivals of 5th century BC tragedies in the pre-Alexandrian age is still in progress and scholars sometimes tend to oversimplify the issues at stake. This is particularly true in the case of tragic reperformances in the demes. The dissemination of tragedy in this context is considered crucial to the understanding of another important phenomenon: the competence of Athenian audiences. According to a widely accepted theory, the poetic dialogue of comic playwrights with tragic texts implies that (1) the public had a good knowledge of tragedies first staged many decades before their parodies and that (2) this knowledge was enhanced by the revivals of Aeschylus’, Sophocles’ and Euripides’ plays in the theatres of Attica. This may well be true, but we should refrain from thinking that every performance recorded in the demes was necessarily a reperformance: the world of Rural Dionysia is so fascinating and the organisation of these dramatic festivals is so complex, that the demes “may even had lessons to teach the city” (P. Wilson). This paper will analyse two dramatic inscriptions (IG I3 970, IG II/III3 4, 1, 498), both deriving from the demes and recording a Sophoclean production, with the aim of showing that even though they possibly refer to two reperformances, there is a series of epigraphical, philological and literary problems that need to be addressed before jumping to hasty conclusions. Laureato a Pisa nel 2013 con una tesi sul finale interpolato dei Sette contro Tebe (relatore E. Medda), nel 2018 ha conseguito il titolo di dottore di ricerca ad Urbino, dopo aver scritto, sotto la supervisione di L. Lomiento, una dissertazione sulla circolazione della tragedia in età pre-alessandrina.

Ha esposto i risultati delle sue ricerche in conferenze tenutesi ad Eichstätt, Mainz, Vancouver, Sydney, Corfù, Oxford, Basilea. Fra i suoi principali interessi vi sono la trasmissione dei testi, la storia del teatro e la ricezione antica della tragedia; nel 2020 ha pubblicato un articolo sulla Commedia di Mezzo in una raccolta di studi in onore di A. Bowie (Ancient Greek Comedy, De Gruyter). Attualmente insegna Lettere nelle scuole superiori ed è un ricercatore indipendente.

description: We study how the Mott metal-insulator transition (MIT) is affected when we have to deal with electrons with different angular momentum quantum numbers. For that purpose we apply ab-initio quantum-chemical methods to lithium rings in order to investigate the analogue of a MIT. By changing the interatomic distance we analyse the character of the many-body wavefunction and discuss the importance of the $s-p$ orbital quasi-degeneracy within the metallic regime. The charge gap (ionization potential minus electron affinity) shows a minimum and the static electric dipole polarizability has a pronounced maximum at a lattice constant where the character of the wavefunction changes from significant $p$ to essentially $s$-type. In addition, we examine rings with bond alternation in order to answer the question under which conditions a Peierls distortion occurs.

title: Next-Generation Sequencing for New Gene Identification and for Diagnosis in Steroid-Resistant Nephrotic Syndrome
Creators: name: Iatropoulos, Paraskevas

description: Nephrotic syndrome is clinically characterized by massive proteinuria, and hypoalbuminemia. It represents a heterogeneous group of glomerular disorders characterized by distinct causes and histopathologic lesions. The present thesis evaluates the contribution of genetics in conditions commonly associated with NS: the immune complex-mediated membranoproliferative glomerulonephritis (IC-MPGN), the C3 glomerulopathy (C3G) and the podocytopathies, usually characterized by steroid-resistant nephrotic syndrome (SRNS). The first part of the thesis focused on IC-MPGN and C3G. We found likely pathogenic (LP) variants in complement alternative pathway genes in 18% of patients and describe, for the first time, thrombomodulin rare pathogenic variants in C3G patients. Interestingly, mutations alone did not increase the risk of developing IC-MPGN or C3G, but they did so when combined with common susceptibility variants. The prevalence of alternative pathway abnormalities (mutations and/or C3 Nephritic Factors, C3NeFs) was similar in IC-MPGN (53-56%) and C3G (64-65%). To investigate for more homogeneous subgroups within IC-MPGN/C3G, an operator-independent approach was applied using genetic, biochemical, histological and clinical data. Four different groups emerged showing distinct pathogenesis, and histological and clinical features. In the second part, the genetic causes of podocytopathies were investigated. LP variants in podocytopathy-associated genes are found in 23% of SRNS patients, prevalently in COL4A3-5 genes. Moreover, 8% of patients carried LP variants in Congenital Anomalies of the Kidney and the Urinary Tract (CAKUT)-associated genes, which were not previously associated with podocytopathies. LP variants in CAKUT-associated and podocytopathy-associated genes frequently combined together. Finally, possibly pathogenic variants in EPB41L45, a candidate gene for podocytopathies, were identified in 3 unrelated patients. In conclusion, this thesis contributes to understand the complex genetic basis of both IC-MPGN/C3G and podocytopathies. It introduces new players in the pathogenesis of these diseases. Finally, it provides evidence of the presence of subgroups within IC-MPGN/C3G with distinct underlying mechanisms, and clinical and histopathologic features.

description: Small-holder farmers in the urban and peri-urban areas have become very vulnerable to land use change patterns due to rapid increase in population and urbanization. Farmlands are gradually being converted to residential facilities, posing significant threat to the livelihood of farmers who depend on such lands. Land use change at Abokobi dates back to the 2004, but the phenomena became more pronounced in 2008 when the Ga East District attained municipal status. With support from the Department of Agriculture, small-holder farmers in Abokobi were offered alternative livelihood programmes in livestock and high yielding crop varieties and non-traditional farming practices under the Heifer Project. This study sought to assess the extent of farmer uptake of the alternative livelihood support programmes. Mixed approaches of qualitative and quantitative methods were used to engage 100 farmers in a survey whiles 12 others were engaged in a focus group discussion. Three project officials were engaged in an in-depth interview. The findings revealed that farmlands were increasingly being sold to estate developers leading to a reduction in farm size, output and income. Of the 100 farmers in the survey, 49 were under the Heifer project, 33 were engaged in their own alternative livelihood activities and 18 were not engaged in any livelihood activity. Those with successful uptake of the Heifer programme had higher income relative to those who did not adopt. The factors that influenced successful uptake of the alternative livelihood programmes were expectation, incentive and benefits from the programme, educational level, age and household size of farmers. The study recommended that providers should engage farmers before introducing them to alternative livelihood programmes, proper and efficient planning of urban areas with much consideration for the preservation of space for agriculture should be considered and continuous education of farmers in peri-urban areas not to depend only on farming.

Ab-Initio Calculation of the Metal-Insulator Transition in Sodium rings and chains and in mixed Sodium-Lithium systems

description: We study how the Mott metal-insulator transition (MIT) is influenced when we deal with electrons with different angular momenta. For lithium we found an essential effect when we include $p$-orbitals in the description of the Hilbert space. We apply quantum-chemical methods to sodium rings and chains in order to investigate the analogue of a MIT, and how it is influenced by periodic and open boundaries. By changing the interatomic distance we analyse the character of the many-body wavefunction and the charge gap. In the second part we mimic a behaviour found in the ionic Hubbard model, where a transition from a band to a Mott insulator occurs. For that purpose we perform calculations for mixed sodium-lithium rings. In addition, we examine the question of bond alternation for the pure sodium system and the mixed sodium-lithium system, in order to determine under which conditions a Peierls distortion occurs.

description: We report on a comprehensive characterization of the newly synthesized Cu$^{2+}$-based molecular magnet [Cu(pz)$_2$(2-HOpy)$_2$](PF$_6$)$_2$ (CuPOF), where pz = C$_4$H$_4$N$_2$ and 2-HOpy = C$_5$H$_4$NHO. From a comparison of theoretical modeling to results of bulk magnetometry, specific heat, $μ^+$SR, ESR, and NMR spectroscopy, this material is determined as an excellent realization of the 2D square-lattice $S=1/2$ antiferromagnetic Heisenberg model with a moderate intraplane nearest-neighbor exchange coupling of $J/k_\mathrm{B} = 6.80(5)$ K, and an extremely small interlayer interaction of about 1 mK. At zero field, the bulk magnetometry reveals a temperature-driven crossover of spin correlations from isotropic to $XY$ type, caused by the presence of a weak intrinsic easy-plane anisotropy. A transition to long-range order, driven by the low-temperature $XY$ anisotropy under the influence of the interlayer coupling, occurs at $T_\mathrm{N} = 1.38(2)$ K, as revealed by $μ^+$SR. In applied magnetic fields, our $^1$H-NMR data reveal a strong increase of the magnetic anisotropy, manifested by a pronounced enhancement of the transition temperature to commensurate long-range order at $T_\mathrm{N} =2.8$ K and 7 T.

Impact of transport modelling on the $^{60}$Fe abundance inside Galactic cosmic ray sources

description: The ACE-CRIS collaboration has recently released the measurement of radioactive $^{60}$Fe nuclei abundance in Galactic Cosmic Rays, in the energy range $\sim 195-500$ MeV per nucleon. We model Cosmic Ray propagation and derive from this measurement the $^{60}$Fe/$^{56}$Fe ratio that is expected in the sources of Galactic Cosmic Rays. We describe Cosmic Ray origin and transport within the framework of the disk/halo diffusion model, namely a scenario in which the matter and the Cosmic Ray sources in our Galaxy are confined to a thin disk, while Cosmic Ray propagation occurs in a much larger halo with negligible matter density. We solve the Cosmic Ray transport equation accounting for spallation reactions, decay and ionization losses as well as advection. We find that the $^{60}$Fe/$^{56}$Fe ratio at the source must be very close to the value detected in the local Cosmic Ray spectrum at Earth, due to the fact that spallation reactions are more effective for $^{56}$Fe than for $^{60}$Fe. Such a result could help identify the sources of Galactic Cosmic Rays.

description: The Jaynes-Cummings model is a cornerstone of light-matter interactions. While finite, the model provides an illustrative example of renormalisation in perturbation theory. We show, however, that exact renormalisation reveals a rich non-perturbative structure, and that the model provides a physical example of a theory with a chaotic coupling trajectory and multi-valued beta-function. We also construct an exact Wilsonian-like renormalisation group flow for the effective scattering matrix, and show how multi-valued features arise in the flow. Our results shed light on non-perturbative aspects of renormalisation and on the structure of the Jaynes-Cummings model itself.

description: Additional file 9 : Figure S6. 3C-qPCR results in the 9q31.2 locus from the HindIII fragment containing the KLF4 gene and promoter. qPCR was carried out on HaCaT and My-La 3C libraries using TaqMan® as the reporter. The anchor fragment (distance 0) contained the entire KLF4 gene and promoter. An intergenic fragment located approximately 200 kb from the anchor fragment was utilised as a negative control region. Eleven test fragments were selected at regular intervals across the psoriasis association. The positive controls in the Dryden BrCa region were included. Asterisks denote fragments that had a significantly higher relative interaction frequency than the NCR (one-way ANOVA, adjusted P-value < 0.05). Bars show mean + SD of triplicate 3C libraries.
