description: As part of a recent analysis of exclusive two-photon production of W+ W- pairs at the LHC, the CMS experiment used di-lepton data to obtain an "effective" photon-photon luminosity. We show how the CMS analysis on their 8 TeV data, along with some assumptions about the likelihood for events in which the proton breaks up to pass the selection criteria, can be used to significantly constrain the photon parton distribution functions, such as those from the CTEQ, MRST, and NNPDF collaborations. We compare the data with predictions using these photon distributions, as well as the new LUXqed photon distribution. We study the impact of including these data on the NNPDF2.3QED, NNPDF3.0QED and CT14QEDinc fits. We find that these data place a usefil and complementary cross-check on the photon distribution, which is consistent with LUXqed prediction while suggesting that the NNPDF photon error band should be significantly reduced. Additionally, we propose a simple model for describing the two-photon production of W+ W- at the LHC. Using this model, we constrain the amount of inelastic photon that remains after the experimental cuts are applied.

description: The development of sophisticated experimental means to control nanoscale systems has motivated efforts to design driving protocols which minimize the energy dissipated to the environment. Computational models are a crucial tool in this practical challenge. We describe a general method for sampling an ensemble of finite-time, nonequilibrium protocols biased towards a low average dissipation. We show that this scheme can be carried out very efficiently in several limiting cases. As an application, we sample the ensemble of low-dissipation protocols that invert the magnetization of a 2D Ising model and explore how the diversity of the protocols varies in response to constraints on the average dissipation. In this example, we find that there is a large set of protocols with average dissipation close to the optimal value, which we argue is a general phenomenon.

description: Lymphatic malformations of the upper limp are a group of lymphatic malformations with different characteristics from those of the trunk. Their etiology remains unknown, with defective action of lymphatic growth regulators thought to be the predominant cause. The purpose of this master's thesis was to present the methods of diagnosis and treatment of lymphatic malformations of the upper limb. We also referred to the embryology and anatomy of the lymphatic system, additionally making a historical review of lymphatic malformations. Due to the complexity of lymphatic malformations of the upper extremity, a multidisciplinary approach by experienced physicians is often mandatory for their ideal management.
Healthcare in the Welfare State: Assessing Emerging Welfare State Typologies in Eastern Europe Using Hierarchical Cluster Analysis
Creators: name: Cheatle, Sean

Year: 2016

description: This paper analyzes welfare state groupings with several cluster analyses on the EU27 and the 10 Central and Eastern European (CEE) states admitted into the EU in 2004 and 2007 using 20 social policy and public healthcare indicators as variables. The focus is on delineating (a) the robustness of the CEE block in the EU27 and (b) the existence of distinct welfare and healthcare groups within Eastern Europe. I found significant quantitative evidence in the cluster analyses of both the eastern welfare state type in the EU27 and the existence of corporatist and developing welfare state types within the eastern welfare state type. Following the cluster analysis, I found significant evidence in my quantitative assessment and the literature on welfare states in Eastern Europe of informal payments, out-of-pocket payments, and public healthcare inefficiency at the state-level as the leading factors in the distinction of states within the CEE10.

description: This note aims to show a uniqueness property for the solution (whenever exists) to the moment problem for the symmetric algebra $S(V)$ of a locally convex space $(V, τ)$. Let $μ$ be a measure representing a linear functional $L: S(V)\to\mathbb{R}$. We deduce a sufficient determinacy condition on $L$ provided that the support of $μ$ is contained in the union of the topological duals of $V$ w.r.t. to countably many of the seminorms in the family inducing $τ$. We compare this result with some already known in literature for such a general form of the moment problem and further discuss how some prior knowledge on the support of the representing measure influences its determinacy.

description: Atrionatriuretisches Peptid (ANP) moduliert die Barrierenfunktion in endothelialen Monolayers; jedoch sind die Mechanismen noch unklar. Wir überprüften die Hypothese, inwiefern die ANP-Wirkung auf die Permeabilität (P) abhängig ist von einem veränderlichen Gleichgewicht der Nukleotide cyclic GMP (cGMP) und cyclic AMP (cAMP), und hierbei der C-ANP-Rezeptor ein funktionelle Bedeutung aufweist. Die ANP-Wirkung wurde hierbei in koronaren (CEC) and aortalen Endothelzellen (AEC) im Vergleich untersucht. Die endotheliale Makromolekülpermeabilität (P) wurde aus dem Übertritt von Trypanblaugelabelten Albumin über das Monolayer ermittelt. Wir erfassten neben der Permeabilität den zellulären Gehalt von cGMP und cAMP, mit und ohne Pertussitoxin (PT), mit dem Proteinkinase G -Inhibitor KT 5823 und mit beiden Substanzen in Kombination. Dann wiederholten wir die gesamte Versuchsserie mit dem ANP-Derivat C-ANP, das selektiv nur an den C-ANP-Rezeptor bindet. Ergebnisse: In CEC verursachte ANP (100nM) eine Abnahme der P (48%+/-7%, mean +/- SD, N=6, p
description: Atrial natriuretic peptide (ANP) improves the barrier function in primary cultures of endothelial monolayers; however, the mechanism is unclear. We tested the hypothesis that the ANP-induced alteration in endothelial permeability is related to an altered balance between cyclic GMP (cGMP) and cyclic AMP (cAMP) via functional involvement of the C-ANP-receptor in coronary endothelial (CEC) and aortic endothelial (AEC) cells. Endothelial macromolecule permeability (P) was determined by passage of trypan-blue-labeled albumin across rat coronary and porc aortic endothelial monolayers. We measured permeability, as well as cGMP and cAMP, with or without pertussis toxin (PT), the protein kinase G inhibitor KT 5823, and both in combination. Next, we repeated this entire series, giving the truncated ANP-derivate C-ANP, which binds only to the C-ANP-receptor. We found: In CEC ANP (100nM) caused a decrease in P (48%+/-7%, mean +/- SD, N=6, p

Detecting Movement Errors in Chronic Ankle Instability Patients: Comparing Fusionetics to the LESS
Creators: name: Harriss, Julie
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Lateral ankle sprains are the most common injuries in sport, and many who have an initial lateral ankle sprain go on to experience recurrent sprains and instability; defined at chronic ankle instability (CAI). The purpose was to determine whether Fusionetics or the Landing Error Scoring System (LESS), movement efficiency exams, are able to detect differences between collegiate athletes with and without CAI. Lower extremity Fusionetics tests (overhead squat, overhead squat with heel lift, and single limb squat) and the LESS were performed. Nonparametric analyses found no differences between groups for any of the five outcome measures. Further, no correlations were found between injury characteristics (questionnaires and number of sprains) and outcome measures within the CAI group. The results indicate that Fusionetics and LESS exams are not able to detect differences between those who have CAI and healthy controls. Neither task are likely ankle specific enough to detect differences.

description: Based on earlier work of the latter two named authors on the higher super-Teichmueller space with $\mathcal{N}=1$, a component of the flat $OSp(1|2)$ connections on a punctured surface, here we extend to the case $\mathcal{N}=2$ of flat $OSp(2|2)$ connections. Indeed, we construct here coordinates on the higher super-Teichmueller space of a surface $F$ with at least one puncture associated to the supergroup $OSp(2|2)$, which in particular specializes to give another treatment for $\mathcal{N}=1$ simpler than the earlier work. The Minkowski space in the current case, where the corresponding super Fuchsian groups act, is replaced by the superspace $\mathbb{R}^{2,2|4}$, and the familiar lambda lengths are extended by odd invariants of triples of special isotropic vectors in $\mathbb{R}^{2,2|4}$ as well as extra bosonic parameters, which we call ratios, defining a flat $\mathbb{R}_{+}$-connection on $F$. As in the pure bosonic or $\mathcal{N}=1$ cases, we derive the analogue of Ptolemy transformations for all these new variables.

description: This study concerns the emergence of nihilism and its overcoming through imagination in the poetic work of the great surrealist poet Andreas Empirikos. Imagination, from its contemplative to its visionary dimension, constitutes space-time, where the union of the sensible and mental world takes place. Surrealism, following the techniques of psychoanalysts for entering the world of the unconscious and the methods of mystics - theosophy, Sufism - for self-concentration and ecstasy fights against the fallacy and conventionality of rationalism and technocracy. Guided by the truth that is experienced in the inner reality, the sensible world can and must be transformed in order for man to find his authenticity. The above positions are identified and studied in his work through the analysis of seemingly opposite pairs. Forms are spiritualized and meanings are embodied to reveal the unity and harmony of the world.
Brill-Noether theory for cyclic covers

description: The Brill-Noether Theorem gives necessary and sufficient conditions for the existence of a linear series. Here we consider a general n-fold, etale cyclic cover p of a curve C of genus g and investigate for which numbers r,d a linear series of dimension r and degree d exists on the covering curve. For r=1 this gives gonality. Using degeneration to a special singular example (containing a Castelnuovo canonical curve) and the theory of of limit linear series for tree-like curves we show that the Plücker formula yields a necessary condition for the existence of a linear series (of dimension r, degree d) which is only slightly weaker than the sufficient condition given by the result of Kleimann and Laksov, for all n,r,d.

description: We present a doubly parametric extension of the standard Froggatt--Nielsen (FN) mechanism. As is well known, mass matrices of the up- and down-type quark sectors and the charged lepton sector in the standard model can be parametrized well by a parameter $λ$ which is usually taken to be the sine of the Cabibbo angle ($λ= \sinθ_\text{C} \simeq 0.225$). However, in the neutrino sector, there is still room to realize the two neutrino mass squared differences $Δm_\text{sol}^2$ and $Δm_\text{atm}^2$, two large mixing angles $θ_{12}$ and $θ_{23}$, and non-zero $θ_{13}$. Then we consider an extension with an additional parameter $ρ$ in addition to $λ$. Taking the relevant FN charges for a power of $λ~(=0.225)$ and additional FN charges for a power of $ρ$, which we assume to be less than one, we can reproduce the ratio of the two neutrino mass squared differences and three mixing angles. In the normal neutrino mass hierarchy, we show several patterns for taking relevant FN charges and the magnitude of $ρ$. We find that if $\sin θ_{23}$ is measured more precisely, we can distinguish each pattern. This is testable in the near future, for example in neutrino oscillation experiments. In addition, we predict the Dirac CP-violating phase for each pattern.

It's all the same, only the names have changed: the impact of the Kosovo issue on domestic politics in post-Milosevic Serbia
Creators: name: O'Donnell, Patrick
Publisher: name: University of North Carolina at Chapel Hill
Year: 2011

description: The purpose of this thesis is to explore the link between the Kosovo issue and Serbian domestic politics. My hypothesis is that Kosovo has been decisive in turning Serbia away from the European Union and the West and toward ultra-nationalism. Shunning the West and EU membership allows corrupt politicians to delay political and economic reforms that would likely impact the way they profit from the Serbian political system. There is also a measure of ethnic outbidding that is taking place. Although some political parties are willing to compromise on Kosovo, they do not feel it is a politically viable position to hold. With the election of Boris Tadic and his pro-reform Democratic Party in 2008, however, Serbia may be ready to move past an issue that has held its politics hostage since the breakup of Yugoslavia in the early 1990s.

description: Soil microorganisms can improve plant health, seedling emergence and growth. Therefore, seed coatings, incorporating microbial amendments, may improve restoration outcomes for native Australian plant species. To assess effectiveness of a suite of different amendments (Vermiwash, Metagen, MycoGold and native soil inoculum) added to AirSeed Technologies’ Seed Pods, two glasshouse trials were conducted for which seeds were sown in soil collected from a restoration site in the Sydney region (Mount Annan) in trial one, and in a microbially-depauperate, autoclaved soil during trial two. Seeds of three Australian native plant Species were bare seeded or encapsulated in amended and non-amended AirSeed Technologies’ Seed Pods. Seedlings were monitored for three months. In the microbially-depauperate soil, growth rates and total dry biomass of seedlings in the native soil Seed Pods were significantly higher compared to non-amended Seed Pod controls (Acacia parramattensis and Hardenbergia violacea) and bare seeds (Acacia parramattensis). None of the amended Seed Pods significantly improved root nodule formation, root:shoot dry biomass ratios, or emergence across all species in both growth media. These results suggest Seed Pods made with native soil provided additional growth benefits in the microbially-depauperate soil relative to non-amended Seed Pods and bare seed controls. Nevertheless, the use of microbial amendments and the application technique may need to be refined to meet specific needs of Australian native plant species and soil characteristics.

Effect of EPA on Intercellular Lipid Droplets Degradation

Year: 2017
Subjects: fish oil

description: Although the beneficial effects of omega-3 fatty acid in reducing the risk of various of human diseases, such as hypertriglyceridemia and nonalcoholic fatty liver disease, have been demonstrated in clinical and pre-clinical studies, the mechanism of its action is poorly understood. several studies has been reported that Dietary supplementation with fish oil induces many changes in plasma TG profile. N-3 fatty acid found in fish oil has been reported that reduce plasma TG and VLDL lev- els. Intercellular lipid droplets is the key regulator of plasma fatty acids and lipoproteins level. Here we show that n-3 fatty acid supplementation triggers intercellular lipid droplets degradation independent from known fatty acid mobilization pathways namely lipophagy and lipolysis . ATGL and HSL are consider as two major lipolysis enzymes.SiRNA study of these two lipolysis enzymes did not attenuate lipid droplets degradation. Lipophagy has been reported as a selective mechanism for degradation of lipid droplets during the starvation condition. Knock down of autophagy (macroautophagy) related pro- teins, could not block degradation of intercellular lipids by EPA. Degradation of lipid droplets is lysosomes dependent and requires lysosomal motility machinery. Lysosomes are interacting directly with lipid droplets during the process that is similar to kiss and run pattern. The morphological examination of this process by electron microscopy indicated its re- semblance to microautophagy like structure. Importantly, (over expression) Arl8b which has been shown that play a role in peripheral distribution of lysosomes along with FYCO1, specifically accelerates the effect of EPA on degradation of intercellular lipid droplets independent from its role in engagement of lysosomal plus end distribution. in particular, Arl8b recruited HOPS protein complex in EPA dependent fashion and si- lencing of HOPS complex interfered with normal lysosomal degradation of lipid droplets. Thus, this finding reveals new mechanism for intercellular lipid mobilization and offer an explanation for the therapeutic benefits of omega-3 fatty acids.

description: This paper examines the impact of a government food subsidy program in different communities on Baffin Island, Nunavut, in order to understand their inefficiencies. It also reviews the concerns that are being expressed by community members via Facebook, the Aboriginal Peoples Television Network (APTN), and the blog website FeedingNunavut.com. The content and thematic analyses applied to this project derive information from established data sources, examined through the theoretical lens of political economy. These issues are framed by historical colonial influences of early European trading dynamics, and demonstrate the ongoing paternal influences of the Federal Government. The thesis argues that, in part because Inuit opinions were disregarded in the implementation of Federal subsidy programs, household food insecurity rates in Northern Canada remain at nearly 70%. With governmental restrictions put on hunting and fishing, Inuit are limited in the maintenance of traditional practices and are turning to store-bought food for sustenance. However, food prices are high and food quality is sometimes low. This study of Inuit food security within Baffin thus contributes to an understanding of power and inequalities in the North.

description: We study the effect of particles shape on the radiative heat transfer in a three-body system. It is found that the radiative heat flux between two nanoparticles in a three body system can be tuned by the shape of the third particle. In particular, we show that the heat flux is very sensitive to the particle shapes and slight mismatches of shapes results in either enhanced or suppressed heat flux.

description: Transcription factors (TFs) exert their regulatory action by binding to DNA with specific sequence preferences. However, different TFs can partially share their binding sequences due to their common evolutionary origin. This `redundancy' of binding defines a way of organizing TFs in `motif families' by grouping TFs with similar binding preferences. Since these ultimately define the TF target genes, the motif family organization entails information about the structure of transcriptional regulation as it has been shaped by evolution. Focusing on the human TF repertoire, we show that a one-parameter evolutionary model of the Birth-Death-Innovation type can explain the TF empirical ripartition in motif families, and allows to highlight the relevant evolutionary forces at the origin of this organization. Moreover, the model allows to pinpoint few deviations from the neutral scenario it assumes: three over-expanded families (including HOX and FOX genes), a set of `singleton' TFs for which duplication seems to be selected against, and a higher-than-average rate of diversification of the binding preferences of TFs with a Zinc Finger DNA binding domain. Finally, a comparison of the TF motif family organization in different eukaryotic species suggests an increase of redundancy of binding with organism complexity.

Re-evaluating genetic models for porphyry Mo mineralization at Questa, New Mexico: Implications for ore deposition following silicic ignimbrite eruption
Creators: name: Rosera, Joshua M.
Publisher: name: University of North Carolina at Chapel Hill
Year: 2012

description: The Questa Mo deposit in New Mexico provides an opportunity to study the relationship between pluton assembly and mineralization. Magmatism along the Questa caldera margin initiated at 25.20 Ma and continued for ~ 770 ka. Emplacement of mineralizing intrusions progressed westward and culminated in the assembly of the Questa Mo deposit between 24.76 and 24.50 Ma. Molybdenite Re-Os ages are integrated with zircon U-Pb and biotite Ar-Ar ages to evaluate the cooling histories within the deposit. These data show that the mineralizing intrusions were generated via rapid melting, separation, and intrusion into the shallow crust without involvement in a long-lived magma chamber. It is proposed that the anomalously high magma flux associated with ignimbrite eruption introduces materials necessary for mineralization. Partial melting and scavenging within a deep-crustal hybridized zone generated Mo-rich magma that formed the Questa deposit. This hypothesis predicts an important connection between caldera-forming systems and porphyry-style mineralization.

description: Quantum systems in contact with an environment display a rich physics emerging from the interplay between dissipative and Hamiltonian terms. Here we focus on the role of the geometry of the coupling between the system and the baths. In the specific we consider a dissipative boundary driven ladder in presence of a gauge field which can be implemented with ion microtraps arrays. We show that, depending on the geometry, the currents imposed by the baths can be strongly affected by the gauge field resulting in non-equilibrium phase transitions. In different phases both the magnitude of the current and its spatial distribution are significantly different. These findings allow for novel strategies to manipulate and control transport properties in quantum systems.

description: Working in the framework of the Standard Model Effective Field Theory, we study chirality-flipping couplings of the top quark to Higgs and gauge bosons. We discuss in detail the renormalization group evolution to lower energies and investigate direct and indirect contributions to high- and low-energy CP-conserving and CP-violating observables. Our analysis includes constraints from collider observables, precision electroweak tests, flavor physics, and electric dipole moments. We find that indirect probes are competitive or dominant for both CP-even and CP-odd observables, even after accounting for uncertainties associated with hadronic and nuclear matrix elements, illustrating the importance of including operator mixing in constraining the Standard Model Effective Field Theory. We also study scenarios where multiple anomalous top couplings are generated at the high scale, showing that while the bounds on individual couplings relax, strong correlations among couplings survive. Finally, we find that enforcing minimal flavor violation does not significantly affect the bounds on the top couplings.

description: We define two related invariants for a $d$-dimensional local ring $(R,\mathfrak{m},k)$ called syzygy and differential symmetric signature by looking at the maximal free splitting of reflexive symmetric powers of two modules: the top dimensional syzygy module $\mathrm{Syz}^d_R(k)$ of the residue field and the module of Kähler differentials $Ω_{R/k}$ of $R$ over $k$. We compute these invariants for two-dimensional ADE singularities obtaining $1/|G|$, where $|G|$ is the order of the acting group, and for cones over elliptic curves obtaining $0$ for the differential symmetric signature. These values coincide with the F-signature of such rings in positive characteristic.

description: We establish an expansion by Gamma-convergence of the Fisher information relative to the reference measure exp(-beta V), where V is a generic multiwell potential and beta goes to infinity. The expansion reveals a hierarchy of multiple scales reflecting the metastable behavior of the underlying overdamped Langevin dynamics: distinct scales emerge and become relevant depending on whether one considers probability measures concentrated on local minima of V, probability measures concentrated on critical points of V, or generic probability measures on R^d. We thus fully describe the asymptotic behavior of minima of the Fisher information over regular sets of probabilities. The analysis mostly relies on spectral properties of diffusion operators and the related semiclassical Witten Laplacian and covers also the case of a compact smooth manifold as underlying space.

Supranational Integration in the Shared Neighborhood: Democratization and Regime Choice in Eastern Europe and the Caucasus

Subjects: subject: Political science

description: In post-communist Central Europe, the European Union effectively used democratic conditionality to generate political reform in candidate states. With the Eurasian Economic Union, Russia now offers the former Soviet countries an alternative to EU integration, without the strings of democratic reform attached. Are less democratic regimes therefore more likely to side with Russia's organization in order to avoid committing to the stringent political reforms needed for EU association? This thesis applies theory on democratic change to four post-Soviet states to evaluate the nature of their political systems and their trajectories towards EU association or EEU membership. A correlation between democratic competitiveness and EU integration can be found in this region, but the lack of a causal link suggests that other factors may be at play.

description: Diese Dissertation handelt vom metastabilen Zerfall und von der Oberflächenwechselwirkung im hyperthermalen Energiebereich relativ schwach gebundener molekularer Kohlenmonoxid und Kohlendioxid Clusterkationen mit einer Edelstahloberfläche und einer Siliziumoberfläche. Im Rahmen dieser Arbeit wurde ein hierfür geeignetes spezielles Flugzeitmassenspektrometer entwickelt und aufgebaut. Entwurf, numerische Optimierung der Auflösung, ionenoptische Simulationen und Aufbau der jeweiligen Komponenten wie Elektronenquellen, Beschleuniger, Ablenkplatten, Massenfilter und Reflektron werden detailliert beschrieben. Das entwickelte Flugzeitmassenspektrometer besitzt mit einer kompakten Gesamtfluglänge von ~1.5m eine hohe Massenauflösung von m/Delta m = 3000. Es bietet die Möglichkeit, eine Massentrennung von Clusterionen mit einer Größe von bis zu n = 190 vorzunehmen. Diese massenselektierten Clusterionen können daraufhin auf metastabilen Zerfall und auf ihre Wechselwirkung mit einer Oberfläche untersucht werden. Dazu wurden Kohlendioxid-Clusterionen mit n
description: This thesis deals with the metastable decay and the surface scattering in the hyperthermal energy range of relatively weakly bound molecular cluster cations. With carbon monoxide and carbon dioxide two related model systems were chosen for a systematic size dependent study. Surface impact experiments were carried out with stainless steel and silicon surfaces. Results were obtained by a new, reflectron time-of-flight mass spectrometer (Re-TOFMS). Additional to the experimental data we present in this work a detailed description of the instrumental design considerations, numerical optimization, ion optical simulations. Hence each ion optical component like electron guns, accelerator, deflector, mass gate and reflectron are described. Despite the compact dimensions with a total flight length of ~1.5m the developed instrument possesses a high mass resolution above m/Delta m = 3000. Additionally it offers the possibility to perform mass separation of big cluster ions with sizes n
Estimating orthant probabilities of high dimensional Gaussian vectors with an application to set estimation

Year: 2016

description: The computation of Gaussian orthant probabilities has been extensively studied for low-dimensional vectors. Here, we focus on the high-dimensional case and we present a two-step procedure relying on both deterministic and stochastic techniques. The proposed estimator relies indeed on splitting the probability into a low-dimensional term and a remainder. While the low-dimensional probability can be estimated by fast and accurate quadrature, the remainder requires Monte Carlo sampling. We further refine the estimation by using a novel asymmetric nested Monte Carlo (anMC) algorithm for the remainder and we highlight cases where this approximation brings substantial efficiency gains. The proposed methods are compared against state-of-the-art techniques in a numerical study, which also calls attention to the advantages and drawbacks of the procedure. Finally, the proposed method is applied to derive conservative estimates of excursion sets of expensive to evaluate deterministic functions under a Gaussian random field prior, without requiring a Markov assumption. Supplementary material for this article is available online.
