description: In order to generate credible 0.1–2 μm spectral energy distributions, the Galaxy and Mass Assembly (GAMA) project requires many gigabytes of imaging data from a number of instruments to be reprocessed into a standard format. In this paper, we discuss the software infrastructure we use, and create self-consistent ugrizYJHK photometry for all sources within the GAMA sample. Using UKIDSS and SDSS archive data, we outline the pre-processing necessary to standardize all images to a common zero-point, the steps taken to correct for the seeing bias across the data set and the creation of gigapixel-scale mosaics of the three 4 × 12 deg2 GAMA regions in each filter. From these mosaics, we extract source catalogues for the GAMA regions using elliptical Kron and Petrosian matched apertures. We also calculate Sérsic magnitudes for all galaxies within the GAMA sample using sigma, a galaxy component modelling wrapper for galfit 3. We compare the resultant photometry directly and also calculate the r-band galaxy luminosity function for all photometric data sets to highlight the uncertainty introduced by the photometric method. We find that (1) changing the object detection threshold has a minor effect on the best-fitting Schechter parameters of the overall population (M*± 0.055 mag, α± 0.014, ϕ*± 0.0005 h3 Mpc−3); (2) there is an offset between data sets that use Kron or Petrosian photometry, regardless of the filter; (3) the decision to use circular or elliptical apertures causes an offset in M* of 0.20 mag; (4) the best-fitting Schechter parameters from total-magnitude photometric systems (such as SDSS modelmag or Sérsic magnitudes) have a steeper faint-end slope than photometric systems based upon Kron or Petrosian measurements; and (5) our Universe’s total luminosity density, when calculated using Kron or Petrosian r-band photometry, is underestimated by at least 15 per cent.

description: The work delineated in this research thesis aims to achieve advances in understanding nuclear structure-function interrelationships. Two natural physiological processes---heat-shock and differentiation---have been used in order to provide a clearer understanding of the "big picture" that links structure and functions together. I have performed experiments using mild or severe heat-shock on HeLa S3 cells and I differentiated L6E9 myoblasts into skeletal muscle fibers. Microscopic and biochemical analysis were used in order to assess the effects of heat-shock and differentiation on nuclear morphology. A series of antibodies specific to the nuclear periphery such as: lam in-associated-polypeptides, emerin, lamins A/C and lamin B were used to analyze structural changes that occurs at the nuclear periphery. Similarly, nuclear matrix antigens such as the proliferating cell nuclear antigen or PCNA, the nucleocytoplasmic shuttling protein 2A7, 2H12 and fibrillarin, two nucleolar proteins, were used as tools to assess structural changes that occur in the nuclear morphology.

description: Graphene has been identified as an emerging horizon for a nanoscale photonic platform because the Fermi level of intrinsic graphene can be engineered to support surface plasmons (SPs). The current solid back electrical gating and chemical doping methods cannot facilitate the demonstration of graphene SPs at the near-infrared (NIR) window because of the limited shift of the Fermi level. Here, we present the evidence for the existence of graphene SPs on a tapered graphene-silicon waveguide tip at a NIR wavelength, employing a surface carrier transfer method with molybdenum trioxides. The coupling between the graphene surface plasmons and the guiding mode in silicon waveguides allows for the observation of the concentrated field of the SPs in the tip by near-field scanning optical microscopy. Thus the hot spot from the concentrated SPs in the graphene layer can be used as a key experimental signature of graphene SPs. The NIR graphene SPs opens a new perspective for optical communications, optical sensing and imaging, and optical data storage with extreme spatial confinement, broad bandwidth and high tunability.
Les médecins experts à la fin du moyen-âge entre pratiques médicales et pratiques judiciaires

description: Les experts au Moyen-Âge sont nombreux et de toute sorte. On y trouve les commissaires, les notaires, les procureurs et les experts. Cette étude a pour but de comprendre le rôle de ces derniers et plus particulièrement des experts en médecine lorsqu'ils intervenaient en justice. L'utilisation d'un riche fonds documentaire composé de sources judiciaires et des lettres de rémission du Trésor des Chartes pour une période allant de 1328 à 1350, a permis de comprendre pourquoi les autorités judiciaires avaient recours aux avis d'experts dans les procès. Il apparaît en effet que le développement du recours à l'expertise correspond à l'évolution des pratiques médicales. Ce changement se traduit par une spécialisation des techniques et une standardisation du geste du praticien. Cette systématicité peut être rapprochée d'une pratique ritualisée, ce qui renforce d'avantage la crédibilité et la véracité de l'avis émis par l'expert. Les avis, une fois transmis sous forme de pronostic aux autorités judiciaires, établissaient la responsabilité du prévenu et déterminaient les chances de survie d'une victime. Ces rapports d'expertise avaient une force probatoire indiscutable et constituaient souvent les seules et uniques preuves à la disposition des juges pour rendre leurs verdicts. En effet, la nouvelle procédure judiciaire développée par Saint Louis un siècle auparavant préférait une procédure inquisitoire basée sur les aveux et témoignages à l'ordalie. L'expert devenait ainsi un témoin de choix pour les autorités judiciaires.

description: This study generated two models which are outdoor router cost estimation model and outdoor Wi-Fi average data speed model. The outdoor router cost estimation model was developed by using own data analysis methods which named Extended Parametric Model based on original Parametric Model. All the parameters were filtered by using P-value regression analysis. The outdoor Wi-Fi average data speed model was developed by collecting experimental data. The model was also validated and improved by using real-world obstacles. By using both models, Internet Service Providers will be encouraged to participate more and select suitable equipment in rural connectivity development.
Operators in the cohomology of nilpotent Lie algebras.
Creators: name: Kebel, Alain Claude.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2001
Subjects: subject: Mathematics.

description: Operators in the cohomology of Lie algebras are defined, and fundamental results are proven. The central representation is shown to be useful, in particular cases, for proving the Toral Rank Conjecture (TRC), which states the logarithm of the total dimension of any nilpotent Lie algebra's cohomology space is greater than or equal to the dimension of the centre. Central representation and secondary operators are used to find hypercube-like structures in the cohomology of the free two-step nilpotent. Lie algebras with two, three and four generators. Also, a theorem about the new operators acting on the cohomology of the Heisenberg Lie algebras, and how these operators interact with Poincare duality for this case, is proven.

Subjects: subject: Engineering, Electronics and Electrical.

description: The naming service is a central component for a distributed system. In this thesis it is investigated the creation of a highly scalable, federated, distributed and load balanced name resolution system supporting persistent names in a flat namespace. A new federation technique is proposed and applied for solving the name resolution problem in a flat namespace. The new federation algorithm proposed in this thesis is based on mapping a set of servers (and their names) into a set of nodes in a graph. Another mapping assigns names to a geometric net where each server manages a local set of nodes representing neighbor names. To retrieve a server reference or resolve a name, a hill climbing like technique is applied. The set of federated servers exposing the same interfaces and having identical implementation operate on the namespace distributed database. Mobile agents are used for the federation server's deployment, link construction and link update. Two implementations of a subset of this federated name resolution system one using Orbix, a CORBA compliant product, and another in Voyager, a standard neutral ORB for mobile computing, are provided as a proof of concept.

description: We present the observation of an extraordinary luminous soft X-ray transient, MAXI J0158-744, by the Monitor of All-sky X-ray Image (MAXI) on 2011 November 11. This transient is characterized by a soft X-ray spectrum, a short duration (1.3 × 103 s < ΔTd < 1.10 × 10 4 s), a rapid rise (<5.5 × 103 s) and a huge peak luminosity of 2 × 1040 erg s–1 in 0.7-7.0 keV band. With Swift observations and optical spectroscopy from the Small and Moderate Aperture Research Telescope System, we confirmed that the transient is a nova explosion, on a white dwarf in a binary with a Be star, located near the Small Magellanic Cloud. An early turn-on of the super-soft X-ray source (SSS) phase (<0.44 days), the short SSS phase duration of about one month, and a 0.92 keV neon emission line found in the third MAXI scan, 1296 s after the first detection, suggest that the explosion involves a small amount of ejecta and is produced on an unusually massive O-Ne white dwarf close to, or possibly over, the Chandrasekhar limit. We propose that the huge luminosity detected with MAXI was due to the fireball phase, a direct manifestation of the ignition of the thermonuclear runaway process in a nova explosion.
A lazy text-based approach to foundational knowledge acquisition.
Creators: name: Massey, Louis.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1995
Subjects: subject: Language, General.

description: Knowledge Acquisition (KA) from text requires that a large quantity of prior knowledge be made available to the Natural Language Processing (NLP) system. This prior knowledge is called foundational knowledge. The question of where foundational knowledge comes from in the first place is one of the biggest problem facing NLP. Conventionally, foundational knowledge has been hand-crafted on a task- and domain-specific basis. However, it is difficult to determine beforehand exactly what knowledge will be required. It has been shown within the TANKA project that a potential solution to this problem is to use surface NLP. Surface NLP relies solely on syntax and on the help of a user to elicit knowledge from text, hence effectively eliminating the need for prior-hand crafting of foundational knowledge. However, the domain knowledge obtained in this manner from a text contains gaps. The work presented in this thesis consisted in finding a better method than prior hand-crafting to acquire the knowledge needed to fill those gaps. The method presented, called Lazy KA, uses examples (short NL stories) and failures of an explanation mechanism such as EBL to find these gaps and to interactively and incrementally learn the required new knowledge. When the explanation of a particular example fails, the user is guided through a process that leads to the acquisition of the missing knowledge. Initially, the user is heavily involved, but as more examples are processed, the user becomes less and less involved. The convergence hypothesis, that is that the user interventions would decrease as examples are processed, was verified experimentally by using the prototype system FOKAS implementing these ideas.

description: Cette these analyse le debat theorique qui oppose Marcel Gauchet et Claude Lefort sur la place du droit dans le fonctionnement democratique ainsi que les debats feministes sur la pertinence d'un recours au droit pour faire avancer les luttes des femmes, notamment en matiere d'avortement. Une analyse detaillee des discours et pratiques de l'Ontario Coalition for Abortion Clinics permet de conclure que l'ambiguite qui caracterise les approches feministes du droit releve d'un paradoxe constitutif des democraties modernes: ces dernieres supposent l'existence de sujets autonomes, auteurs reflexifs et conscients de leur devenir alors que la realistion de leur autonomic repose sur l'inconscience des mecanismes qui les organisent en societe. Les revendications de droits participent de ce paradoxe dans la mesure ou, tout en paraissant limiter le politique (Gauchet), elles sont le vecteur de la participation des acteurs sociaux a la vitalite du politique car elles renvoient a une fonction symbolique du Droit comme Reference normative et arene de debats discursifs (Lefort).

description: We present an analysis of the relationship between molecular gas and current star formation rate surface density at sub-kiloparsec and kiloparsec scales in a sample of 14 nearby star-forming galaxies. Measuring the relationship in the bright, high molecular gas surface density (∑H2 ≳ 20M⊙ pc?2) regions of the disks to minimize the contribution from diffuse extended emission, we find an approximately linear relation between molecular gas and star formation rate surface density, Nmol ∼ 0.96 ± 0.16, with a molecular gas depletion time, τdepmol ∼ 2.30 ± 1.32 Gyr. We show that in the molecular regions of our galaxies there are no clear correlations between τdepmol and the free-fall and effective Jeans dynamical times throughout the sample. We do not find strong trends in the power-law index of the spatially resolved molecular gas star formation law or the molecular gas depletion time across the range of galactic stellar masses sampled (M* ∼ 109.710 11.5M⊙). There is a trend, however, in global measurements that is particularly marked for low-mass galaxies. We suggest that this trend is probably due to the low surface brightness CO J = 10, and it is likely associated with changes in CO-to-H2 conversion factor.

description: The under-performance of regional development in Australia requires a new way of thinking to produce significant change. Futures frameworks can produce this transformation. The research investigated such capacity. It adopted a systems approach and a multi-perspective view within a futures framework formed the basis of the work. It involved a general approach which was compared and contrasted with the outcomes from a particular region. The outcomes show that futures frameworks have the capacity to transform economic development in many ways and this research offers a way to enhance the contribution to regional socio-economic well-being from economic development.

description: Thin film composite membranes were prepared by coating the surface of polyethersulfone ultrafilnation membranes with dilute solutions of sulfonated poly(2,6-dimethyl-1,4-phenylene oxide) polymer. Poly(2,6-dimethyl-1,4-phenylene oxide) was first sulfonated to different degrees, thus obtaining polymers of different ion exchange capacities, from which the coating solutions in methanol or methanol/chloroform mixtures were prepared. The reverse osmosis performance of the thin film composite membranes was studied using electrolyte solutes of different valences and ionic radii. The effect of the solvent used for the preparation of the polymer solution for surface coating was also investigated through testing the performance of the composite membranes in separating different electrolyte solutions as well as by micrographic techniques using a Scanning Electron Microscope and an Atomic Force Microscope. It was found that the preparation of thin film composite membranes with high selectivity and high flux was possible by adjusting properly the ion exchange capacity and the solvent used in making the coating solution. It was also found that the membrane performance was governed primarily by the ion exchange reaction between the solute cation and the proton in-SO$\sb3\sp{-}$H$\sp{+},$ as well as by the Donnan equilibrium. An attempt was also made to investigate the effect of changing the microporous substrate of the thin film composite membrane on the membrane permeation rate and selectivity. The porosity and the structure of the substrate play a significant role in determining the performance of the composit membrane.

description: Hintergrund/ Fragestellung: Schmerz wird peripher von Nozizeptoren detektiert und ins zentrale Nervensystem weitergeleitet. Hier kommt es zur Wahrnehmung, Lokalisation und Bewertung des Schmerzes. Wiederkehrender Schmerz führt zur Chronifizierung. Chronische Schmerzen führen zu spezifischen Veränderungen sowohl im zentralen als auch im peripheren Nervensystem. Ziel war es zu untersuchen, ob der Motorkortex einen Einfluss besitzt, um die Schmerzwahrnehmung bei Gesunden und Schmerzpatienten zu verändern. Zusätzlich wurde getestet, ob der Motorkortex eine geeignete Zielstruktur darstellt, um eine Einschätzung über Krankheitsstadien bei zwei Modell-Erkrankungen (Patienten mit chronischen Schmerzen oder einer Enzephalitis) zu treffen. Methoden: Eine mentale Aufgabe sowie die transkranielle Gleichstromstimulation (tDCS) wurden auf Veränderungen in der Druckschmerzschwelle und der kortikalen Exzitabilität (mittels transkranieller Magnetstimulation (TMS)) bzw. der funktionellen Konnektivität (mittels Magnetresonanztomographie (MRT)) getestet. Es wurden gesunde Probanden und Schmerzpatienten mit einer chronisch entzündlichen Darmerkrankung (CED) und chronisch myofaszialen Schmerzen untersucht. Weiter wurde geprüft, ob neurophysio-logische TMS-Parameter des Motorkortex mit klinischen Skalen für Krankheitsstadien (Schmerz-Katastrophisieren-Skala oder modifizierte Rankin-Skala) korrelieren. Ergebnisse: Die Arbeiten zeigen, dass die Aktivierung des Motorkortex im Zusammen-hang mit der Schmerzwahrnehmung steht. Dabei erscheint eine gesteigerte Motorkortex-Exzitabilität mit einer Schmerzreduktion einherzugehen und umgekehrt eine reduzierte Exzitabilität mit einer Schmerzsteigerung. Die tDCS-Therapie, die die Motorkortexaktivität steigert, führte bei CED-Patienten mit chronischen Schmerzen zu einer signifikanten Schmerzreduktion. Dies war von einer Veränderung in der Ruhezustands-MRT im Sinne einer gesteigerten funktionellen Konnektivität in verschiedenen Gehirnnetzwerken begleitet. Zudem zeigten sich signifikante Assoziationen zwischen verschiedenen TMS-Parametern der Motorkortex-Exzitabilität und den gewählten klinischen Skalen. Schlussfolgerungen: Der Motorkortex und dessen Aktivitätssteigerung haben einen bedeutenden Einfluss auf die Schmerzreduktion bzw. vermitteln diese. Die gewonnenen Erkenntnisse können für eine neue, multimodale Schmerztherapie genutzt werden. Darüber hinaus bietet der Motorkortex eine mögliche Zielstruktur, um nicht-invasiv eine Einschätzung der Erkrankungsschwere bei bestimmten Krankheiten zu treffen.

description: The blue compact dwarf galaxy I Zw 18 is one of the most metal-poor systems known in the local universe (12+log(O/H) = 7.17). In this work we study I Zw 18 using data from Spitzer, Herschel Space Telescope, and IRAM Plateau de Bure Interferometer. Our data set includes the most sensitive maps of I Zw 18, to date, in both the far-infrared and the CO J = 1 → 0 transition. We use dust emission models to derive a dust mass upper limit of only M dust ≤ 1.1 × 104M (3σ limit). This upper limit is driven by the non-detection at 160 μm, and it is a factor of 4-10 times smaller than previous estimates (depending on the model used). We also estimate an upper limit to the total dust-to-gas mass ratio of M Dust/M gas ≤ 5.0 × 10-5. If a linear correlation between the dust-to-gas mass ratio and metallicity (measured as O/H) were to hold, we would expect a ratio of 3.9 × 10-4. We also show that the infrared spectral energy distribution is similar to that of starbursting systems.

description: In my thesis I propose a new interpretation of Book I of A Treatise of Human Nature by David Hume. I claim that this Book must be read in the light of the Introduction to the Treatise. Thus, my interpretation revolves around Hume's intention of creating a new system of the sciences on the basis of his science of man. In this thesis I pay close attention to the following subjects: the analysis of the 'vulgar'; Hume's discussion about the impact of predispositions on our ideas; the distinction between the concept of causation and the process of causation. Finally, I discuss Hume's position on the question of the simplicity and complexity of ideas.

description: Purpose It is known that endothelial cells in the kidney are also strongly VEGF-dependent. Whether intravitreal drugs can be detected within the glomeruli or affect VEGF in glomerular podocytes is not known. Therefore, the aim of this pilot study was to investigate the effects of a single intravitreal injection of aflibercept and ranibizumab on glomeruli of monkeys. Methods The kidneys of eight cynomolgus monkeys, which were intravitreally injected either with 2 mg of aflibercept or with 0.5 mg of ranibizumab, were investigated one and seven days after injection. Two animals served as controls. The distribution of aflibercept, ranibizumab and VEGF was evaluated using anti-Fc- or anti-F(ab)-fragment and anti-VEGF antibodies respectively. The ratio of stained area/nuclei was calculated using a semi-quantitative computer assisted method. Glomerular endothelial cell fenestration was quantified in electron microscopy using a systematic uniform random sampling protocol and estimating the ratio of fenestrae per µm. Results Compared to the controls, the anti-VEGF stained area/nuclei ratio of the ranibizumab-treated animals showed no significant changes whereas the stained areas of the aflibercept-treated monkeys showed a significant decrease post-treatment. Immune reactivity (IR) against aflibercept or ranibizumab was detected in aflibercept- or ranibizumab treated animals respectively. The number of fenestrations of the glomerular endothelial cells has shown no significant differences except one day after aflibercept injection in which the number was increased. Conclusion Surprisingly, both drugs could be detected within the capillaries of the glomeruli. After a single intravitreal injection of aflibercept, VEGF IR in the podocytes was significantly reduced compared to controls. Ranibizumab injection had no significant effect on the glomeruli's VEGF level. Whether this is caused by aflibercept's higher affinity to VEGF or because it is used in a higher stoichiometric concentration compared to ranibizumab remains to be investigated.

description: We investigate the correlation between CO and H I emission in 18 nearby galaxies from the CARMA Survey Toward IR-Bright Nearby Galaxies (STING) at sub-kpc and kpc scales. Our sample, spanning a wide range in stellar mass and metallicity, reveals evidence for a metallicity dependence of the H I column density measured in regions exhibiting CO emission. Such a dependence is predicted by the equilibrium model of McKee and Krumholz, which balances H 2 formation and dissociation. The observed H I column density is often smaller than predicted by the model, an effect we attribute to unresolved clumping, although values close to the model prediction are also seen. We do not observe H I column densities much larger than predicted, as might be expected were there a diffuse H I component that did not contribute to H2 shielding. We also find that the H2 column density inferred from CO correlates strongly with the stellar surface density, suggesting that the local supply of molecular gas is tightly regulated by the stellar disk.

Design: Sensitivity, positive predictive value (PPV), and concordance were calculated by comparing two municipal and two commercial secondary datasets with ground-truthed data collected within 800m buffers surrounding 26 schools. Logistic regression examined associations between sensitivity and PPV with commercial density and neighborhood socioeconomic deprivation. Kendall's Tau estimated correlations between density and proximity of food outlets near schools constructed with secondary datasets versus ground-truthed data. Setting: Vancouver, Canada. Subjects: Food retailers located within 800m of 26 schools Results: All datasets scored relatively poorly across validity measures, though overall, municipal datasets had higher levels of validity than did commercial datasets. Food outlets were more likely to be missing from municipal health inspections lists and commercial datasets in neighborhoods with higher commercial density. Still, both proximity and density measures constructed from all secondary datasets were highly correlated (Kendall’s Tau> 0.70) with measures constructed from ground-truthed data. Conclusions: Despite relatively low levels of validity in all secondary datasets examined, food environment measures constructed from secondary datasets remained highly correlated with ground-truthed data. Findings suggest that secondary datasets can be used to measure the food environment, though estimates should be treated with caution in areas with high commercial density.

description: Beckett scholarship has, on the whole, neglected to probe whether there is anything deeper at 
work behind the persistent references to Romanticism in Beckett’s writing, preferring instead 
to follow the general consensus that it barely operates on the periphery of Beckett’s creative 
practice. Yet ‘still today, when I walk there, I find its vestiges’,1 vestiges which prove vital to 
casting new light on how and why Beckett wrote the way he did, in structural and formal as 
well as thematic terms. In 2004, C. J. Ackerley and S. E. Gontarski noted that a ‘good study of 
the Romantic impulse in SB’s writings, revealing unexpected insights into a tradition 
vehemently rejected but never quite denied, is currently lacking’.2 Three years later, Dirk Van 
Hulle and Mark Nixon, editing the special issue to Samuel Beckett Today / Aujourd’hui
dedicated to Beckett and Romanticism, wrote that the issue ‘tries to give an impetus to the 
study of this complex theme’.3 Enoch Brater reiterated the call again in 2011: ‘Yet how Beckett 
liberates himself from parody to confront the romanticism inherent in his own “profounds of 
mind” is a story of artistic maturity still waiting to be told’.4 This thesis attempts to answer 
these calls in a way which discovers Beckett’s Romanticism not as counterintuitive to his 
poetics of the unsaid but rather as directly connected to it. His Romanticism plays a central role 
in his artistic maturity into minimalism and silence.

description: Objective: To examine whether characteristics of children and adolescents who start lifestyle intervention (LI) for obesity in Germany changed over the last decade. Methods: 65,453 subjects (<21 years) from the APV database (Adiposity Patients Registry) with a BMI ≥ 90th percentile were included (years 2005-2015). Logistic regression models (confounders: age, sex, migration background) were created for overweight, obesity, extreme obesity, and obesity-related comorbidities. Comorbidities were further adjusted for weight category. Results were stratified by inpatient or outpatient care. Results: Extreme obesity was found to be more frequent at the onset of LI (2005: 11.6; 2015: 12.7%) with a similar trend in subgroups (p < 0.001). Obesity increased (2005: 50.3%; 2015: 55.1%), and overweight decreased (2005: 34.1%; 2015: 29.0%) in the whole study population. Trends were similar for inpatient or outpatient care (all p < 0.001). Hypertension increased from 45.7% to 49.2% in the whole study population, and similar data were obtained in the subgroup of inpatients (both p < 0.0001). Dyslipidemia increased in all patients (2005: 21.9%; 2015: 28.0%) and in inpatients (2005: 20.2%; 2015: 25.7%; both p < 0.0001). Abnormal carbohydrate metabolism rose in all patients (from 5.2 to 6.4%; p = 0.0002) without significant trends in subgroups. Conclusion: During the last decade, children and adolescents presented with higher BMI SDS at the onset of LI and the proportion with obesity-related comorbidities increased. Particularly the presence of comorbidities differed between outpatients and inpatients.
title: Differential equations and the diagrammatic coaction of cut Feynman integrals

description: Feynman integrals in dimensional regularization can be expressed as linear combinations of master integrals. This decomposition holds at the level of integrands, where each basis element corresponds to a Feynman integrand, characterized by a set of propagator powers and momenta products, integrated over a contour with vanishing boundary terms. Each master integrand has a dual master contour encircling all propagator poles present at the integrand. At one loop, each subtopology has a unique master integrand and corresponding master contour, whereas, at higher loops, multiple master integrands and and corresponding master contours may exist. Feynman integrals obey a Hopf algebra structure in which the coaction map decomposes each element into a linear combination of tensor products of simpler elements. In each tensor product, the left entry is identified by its integrand, defining a topology associated with the Feynman integral, while the right entry is identified by its integration contour, thus defining a cut Feynman integral. At the one-loop level, Feynman integrals admit a coaction, which may be interpreted entirely diagrammatically. Although recent progress has extended this framework to two loops and beyond, a general theory for constructing a basis of master integrands and contours is yet to be determined. In this work, we extend the established formalism of basis construction by uniquely identifying cut integrals, including region-dependent contributions proportional to iπ. This is accomplished by expressing cut integrals through differential equations. Specifically, we construct the Picard-Fuchs operator associated with both the top topology and subtopologies. In each case, we view uncut integrals as inhomogeneous differential equations, where each inhomogeneous term is induced by the cut dual to its associated integrand. The particular solutions of these inhomogeneous differential equations are then used to define cuts of the top topology. This framework enables us to express the uncut results as linear combinations of cut Feynman integrals. Additionally, by examining the coaction on these cuts, we can reconstruct the coaction of the uncut Feynman integrals. We place particular emphasis on the family of integrals associated with the two-loop massless double box, serving as an insightful example for the coaction formulation beyond one loop. We demonstrate how relations among the family of cut contours and associated integrands can be used to simplify the form of the cut differential equations, allowing us to obtain expressions for its cuts, in terms of which we express the uncut result. Using the coaction of the cuts, we construct a basis for the coaction of the massless double box. Where possible, results are presented in a closed form in the dimensional regulator.

description: Surveillance data indicate that most circulating A(H1N1)pdm09 influenza viruses have remained antigenically similar since they emerged in humans in 2009. However, antigenic drift is likely to occur in the future in response to increasing population immunity induced by infection or vaccination. In this study, sequential passaging of A(H1N1)pdm09 virus by contact transmission through two independent series of suboptimally vaccinated ferrets resulted in selection of variant viruses with an amino acid substitution (N156K, H1 numbering without signal peptide; N159K, H3 numbering without signal peptide; N173K, H1 numbering from first methionine) in a known antigenic site of the viral HA. The N156K HA variant replicated and transmitted efficiently between naïve ferrets and outgrew wildtype virus in vivo in ferrets in the presence and absence of immune pressure. In vitro, in a range of cell culture systems, the N156K variant rapidly adapted, acquiring additional mutations in the viral HA that also potentially affected antigenic properties. The N156K escape mutant was antigenically distinct from wildtype virus as shown by binding of HA-specific antibodies. Glycan binding assays demonstrated the N156K escape mutant had altered receptor binding preferences compared to wildtype virus, which was supported by computational modeling predictions. The N156K substitution, and culture adaptations, have been detected in human A(H1N1)pdm09 viruses with N156K preferentially reported in sequences from original clinical samples rather than cultured isolates. This study demonstrates the ability of the A(H1N1)pdm09 virus to undergo rapid antigenic change to evade a low level vaccine response, while remaining fit in a ferret transmission model of immunization and infection. Furthermore, the potential changes in receptor binding properties that accompany antigenic changes highlight the importance of routine characterization of clinical samples in human A(H1N1)pdm09 influenza surveillance.

description: Background Non-alcoholic fatty liver disease (NAFLD) has a broad spectrum of disease states ranging from mild steatosis characterized by an abnormal retention of lipids within liver cells to steatohepatitis (NASH) showing fat accumulation, inflammation, ballooning and degradation of hepatocytes, and fibrosis. Ultimately, steatohepatitis can result in liver cirrhosis and hepatocellular carcinoma. Methodology and Results In this study we have analyzed three different mouse strains, A/J, C57BL/6J, and PWD/PhJ, that show different degrees of steatohepatitis when administered a 3,5-diethoxycarbonyl-1,4-dihydrocollidin​e(DDC) containing diet. RNA-Seq gene expression analysis, protein analysis and metabolic profiling were applied to identify differentially expressed genes/proteins and perturbed metabolite levels of mouse liver samples upon DDC-treatment. Pathway analysis revealed alteration of arachidonic acid (AA) and S-adenosylmethionine (SAMe) metabolism upon other pathways. To understand metabolic changes of arachidonic acid metabolism in the light of disease expression profiles a kinetic model of this pathway was developed and optimized according to metabolite levels. Subsequently, the model was used to study in silico effects of potential drug targets for steatohepatitis. Conclusions We identified AA/eicosanoid metabolism as highly perturbed in DDC-induced mice using a combination of an experimental and in silico approach. Our analysis of the AA/eicosanoid metabolic pathway suggests that 5-hydroxyeicosatetraenoic acid (5-HETE), 15-hydroxyeicosatetraenoic acid (15-HETE) and prostaglandin D2 (PGD2) are perturbed in DDC mice. We further demonstrate that a dynamic model can be used for qualitative prediction of metabolic changes based on transcriptomics data in a disease-related context. Furthermore, SAMe metabolism was identified as being perturbed due to DDC treatment. Several genes as well as some metabolites of this module show differences between A/J and C57BL/6J on the one hand and PWD/PhJ on the other.
