description: An integer additive set-indexer is defined as an injective function $f:V(G)\rightarrow 2^{\mathbb{N}_0}$ such that the induced function $g_f:E(G) \rightarrow 2^{\mathbb{N}_0}$ defined by $g_f (uv) = f(u)+ f(v)$ is also injective, where $f(u)+f(v)$ is the sum set of $f(u)$ and $f(v)$ and $\mathbb{N}_0$ is the set of all non-negative integers. If $g_f(uv)=k \forall uv\in E(G)$, then $f$ is said to be a $k$-uniform integer additive set-indexers. An integer additive set-indexer $f$ is said to be a weak integer additive set-indexer if $|g_f(uv)|=max(|f(u)|,|f(v)|) \forall uv\in E(G)$. A weak integer additive set-indexer $f$ is called a weakly $k$-uniform integer additive set-indexer if $g_f(e)=k \forall e\in E(G)$. We have some characteristics of the graphs which admit weak and weakly uniform integer additive set-indexers. In this paper, we study the admissibility of weak integer additive set-indexer by certain graphs and finite graph operations.

On configurations where the Loomis-Whitney inequality is nearly sharp and applications to the Furstenberg set problem

description: In this paper, we consider the so-called "Furstenberg set problem" in high dimensions. First, following Wolff's work on the two dimensional real case, we provide "reasonable" upper bounds for the problem for $\mathbb{R}$ or $\mathbb{F}_p$. Next we study the "critical" case and improve the "trivial" exponent by $Ω(\frac{1}{n^2})$ for $\mathbb{F}_p^n$. Our key tool to obtain this lower bound is a theorem about how things behave when the Loomis-Whitney inequality is nearly sharp, as it helps us to reduce the problem down to dimension two.

description: Landauer's principle states that it costs at least kTln2 of work to reset one bit in the presence of a heat bath at temperature T. The bound of kTln2 is achieved in the unphysical infinite-time limit. Here we ask what is possible if one is restricted to finite-time protocols. We prove analytically that it is possible to reset a bit with a work cost close to kTln2 in a finite time. We construct an explicit protocol that achieves this, which involves changing the system's Hamiltonian avoiding quantum coherences, and thermalising. Using concepts and techniques pertaining to single-shot statistical mechanics, we further develop the limit on the work cost, proving that the heat dissipated is close to the minimal possible not just on average, but guaranteed with high confidence in every run. Moreover we exploit the protocol to design a quantum heat engine that works near the Carnot efficiency in finite time.

description: Transverse Anderson localization of light allows localized optical-beam-transport through a transversely-disordered and longitudinally-invariant medium. Its successful implementation in disordered optical fibers recently resulted in the propagation of localized beams of radii comparable with that of conventional optical fibers. We present what is, to the best of our knowledge, the first demonstration of optical image transport using transverse Anderson localization of light. The image transport quality obtained in the polymer disordered optical fiber is comparable with or better than some of the best commercially available multicore image fibers with less pixelation and higher contrast. It is argued that considerable improvement in image transport quality can be obtained in a disordered fiber made from a glass matrix with near wavelength-size randomly distributed air-holes with an air-hole fill-fraction of $50\%$. Our results open the way to device-level implementation of the transverse Anderson localization of light with potential applications in biological and medical imaging.

description: We propose a method to reach the antiferromagnetic state of two-dimensional Fermi gases trapped in optical lattices: Independent subsystems are prepared in suitable initial states and then connected by a sudden or slow quench of the tunneling between the subsystems. Examples of suitable low-entropy subsystems are double wells or plaquettes, which can be experimentally realised in Mott insulating shells using optical super-lattices. We estimate the effective temperature T* of the system after the quench by calculating the distribution of excitations created using the spin wave approximation in a Heisenberg model. We investigate the effect of an initial staggered magnetic field and find that for an optimal polarisation of the initial state the effective temperature can be significantly reduced from T*$\approx$1.7 Tc at zero polarisation to T*<0.65Tc, where Tc is the crossover temperature to the antiferromagnetic state. The temperature can be further reduced using a finite quench time. We also show that T* decreases logarithmically with the linear size of the subsystem.

description: We present a simple model that achieves $m_h\approx 126$ GeV in the MSSM with large $A$-terms and TeV-scale stops through a combination of gauge mediation and Higgs-messenger interactions. The $μ$/$B_μ$ and $A$/$m_H^2$ problems are both solved by a common mechanism -- partial sequestering from strong hidden sector dynamics. Using the framework of General Messenger Higgs Mediation, we explicitly calculate the soft masses in terms of the vacuum expectation values, operator dimensions and OPE coefficients of the strongly-coupled hidden sector. Along the way, we also present a general analysis of the various constraints on sequestered Higgs mediation models. The phenomenology of such models is similar to gaugino mediation, but with large $A$-terms. The NLSP is always long-lived and is either the lightest stau or the Higgsino. The colored states are typically out of reach of the 8 TeV LHC, but may be accessible at 14 TeV, especially if the NLSP is the lightest stau.

Modeling and simulation for causal inference with longitudinal data
Creators: name: Bartels, Christian
Publisher: name: figshare
Year: 2022
Subjects: subject: Statistics
subject: FOS: Mathematics

description: Modeling and simulation is proposed as a method for causal inference with longitudinal data. The estimation equations for causal inference with longitudinal data, which are also known as g-computation, are derived from assumptions on sequential conditional exchangeability. The resulting estimation equations can be evaluated using modeling and simulations. The causal questions that can be answered with modeling and simulation depend on the exchangeability assumptions that can be made. With the assumptions proposed here, the joint distribution of the outcomes can be assessed. The modeling and simulation strategy remains the same independent of the assumptions, build a longitudinal model based on the observed data, use it for simulations, and summarize the results.
Lyman-alpha Heating of Inhomogeneous High-redshift Intergalactic Medium

description: The intergalactic medium (IGM) prior to the epoch of reionization consists mostly of neutral hydrogen gas. Ly-alpha photons produced by early stars resonantly scatter off hydrogen atoms, causing energy exchange between the radiation field and the gas. This interaction results in moderate heating of the gas due to the recoil of the atoms upon scattering, which is of great interest for future studies of the pre-reionization IGM in the HI 21 cm line. We investigate the effect of this Ly-alpha heating in the IGM with linear density, temperature, and velocity perturbations. Perturbations smaller than the diffusion length of photons could be damped due to heat conduction by Ly-alpha photons. The scale at which damping occurs and the strength of this effect depend on various properties of the gas, the flux of Ly-alpha photons and the way in which photon frequencies are redistributed upon scattering. To find the relevant length scale and the extent to which Ly-alpha heating affects perturbations, we calculate the gas heating rates by numerically solving linearized Boltzmann equations in which scattering is treated by the Fokker-Planck approximation. We find that (1) perturbations add a small correction to the gas heating rate, and (2) the damping of temperature perturbations occurs at scales with comoving wavenumber k>10^4 Mpc^{-1}, which are much smaller than the Jeans scale and thus unlikely to substantially affect the observed 21 cm signal.

description: This is my attempt to derive g-computation from sequential conditional exchangeability assumptions. The document is organized in three parts, first notation is introduced by deriving g-computation from conditional exchangeability for a single treatment without time-varying components. Then a first attempt is made to derive g-computation for a time-varying treatment from sequential exchangeability conditions proposed in the literature. With this first attempt I fail. Then a derivation is proposed, which seems to work but is based on slightly different sequential exchangeability conditions. I would appreciate help or comments.

description: To each quadratic number field $K$ and each quadratic polynomial $f$ with $K$-coefficients, one can associate a finite directed graph $G(f,K)$ whose vertices are the $K$-rational preperiodic points for $f$, and whose edges reflect the action of $f$ on these points. This paper has two main goals. (1) For an abstract directed graph $G$, classify the pairs $(K,f)$ such that the isomorphism class of $G$ is realized by $G(f,K)$. We succeed completely for many graphs $G$ by applying a variety of dynamical and Diophantine techniques. (2) Give a complete description of the set of isomorphism classes of graphs that can be realized by some $G(f,K)$. A conjecture of Morton and Silverman implies that this set is finite. Based on our theoretical considerations and a wealth of empirical evidence derived from an algorithm that is developed in this paper, we speculate on a complete list of isomorphism classes of graphs that arise from quadratic polynomials over quadratic fields.

Der vorliegende Artikel betrachtet die Gruppe der fortgeschrittenen Nutzer: Masterstudierende und Promovierende. Aktuelle Angebote für diese Zielgruppen werden beispielhaft dargestellt, gefolgt von möglichen Themen und Konzepten zu ihrer weiteren Unterstützung. Hierbei fließen in der Literatur verfügbare Umfrageergebnisse ein. Für die Gruppe der Doktorandinnen und Doktoranden wurde zudem eine eigene Online-Umfrage durchgeführt. Sie gibt Aufschluss über die Selbsteinschätzung der Teilnehmer bezüglich ihrer persönlichen Informationskompetenz, deren Erwerb, relevante Inhalte und geeignete Formen entsprechender Angebote. Die Ergebnisse werden zusammenfassend wiedergegeben und in einem Anhang in Diagrammen ausführlich dargestellt. Erwartungsgemäß befinden sich konkrete Angebote zur Vermittlung von Informationskompetenz an fortgeschrittene Nutzer noch im Aufbau. Die relevanten Themen ähneln grundsätzlich jenen für Studienanfänger, jedoch sind ein ausgeprägter fachlicher Bezug und die Vertiefung von Inhalten bedeutsam. Beide Gruppen benötigen Angebote zu allgemeinen Recherchestrategien, zur Identifizierung fachspezifischer Angebote sowie zur Nutzung von Datenbanken und Literaturverwaltungssoftware. Für Masterstudierende hat zudem die Internetrecherche sowie die Schaffung eines Bewusstseins für Plagiarismus und richtiges Zitieren Relevanz. Doktorandinnen und Doktoranden zeigen ein gesteigertes Interesse am elektronischen Publizieren, der Veröffentlichung von Fachartikeln und der Nutzung von E-Publikationen. Für Masterstudierende eigenen sich intracurriculare Schulungsangebote, Angebote im Rahmen von Seminaren und verpflichtende fachspezifische Workshop in Zusammenarbeit mit den Fachbereichen, möglicherweise ergänzt (jedoch nicht ersetzt) durch E-Learning-Angebote. Optionale Workshops sollten möglichst im Wahlpflichtbereich belegt werden können. Für Doktorandinnen und Doktoranden ist eine Integration von Angeboten in die formale Doktorandenausbildung, soweit an der jeweiligen Hochschule praktiziert, sinnvoll. Darüber hinaus ist ihnen selbstbestimmtes Lernen zu ermöglichen. Kurse und Workshops sollten möglichst als kompakte eintägige Veranstaltungen konzipiert werden. Auch sonstige Angebote wie Online-Tutorials u. ä. sollten kompakt und präzise auf die relevanten Themen eingehen. Nicht zuletzt ist auch die Möglichkeit zur Einzelberatung für beide Gruppen wichtig.

description: Diffusion of cosmic rays (CRs) is the key process of understanding their propagation and acceleration. We employ the description of spatial separation of magnetic field lines in MHD turbulence in Lazarian & Vishniac (1999) to quantify the divergence of magnetic field on scales less than the injection scale of turbulence and show this divergence induces superdiffusion of CR in the direction perpendicular to the mean magnetic field. The perpendicular displacement squared increases, not as distance $x$ along magnetic field, which is the case for a regular diffusion, but as the $x^{3}$ for freely streaming CRs. The dependence changes to $x^{3/2}$ for the CRs propagating diffusively along magnetic field. In the latter case we show that it is important to distinguish the perpendicular displacement in respect to the mean field and to the local magnetic field. We consider how superdiffusion changes the acceleration of CRs in shocks and show how it decreases efficiency of the CRs acceleration in perpendicular shocks. We also demonstrate that in the case when small-scale magnetic field is being generated in the pre-shock region, an efficient acceleration can take place for the CRs streaming without collisions along magnetic loops.

description: Purpose: The purpose of this study was to evaluate the feasibility and acceptability of a technology-assisted behavioral sleep intervention (Sleep-Opt-In) and to examine the effects of Sleep-Opt-In on sleep duration and regularity, glucose indices, and patient-reported outcomes. Short sleep duration and irregular sleep schedules are associated with reduced glycemic control and greater glycemic variability. Methods: A randomized controlled parallel-arm pilot study was employed. Adults with type 1 diabetes (n = 14) were recruited from the Midwest and randomized 3:2 to the sleep-optimization (Sleep-Opt-In) or Healthy Living attention control group. Sleep-Opt-In was an 8-week, remotely delivered intervention consisting of digital lessons, sleep tracker, and weekly coaching phone calls by a trained sleep coach. Assessments of sleep (actigraphy), glucose (A1C, continuous glucose monitoring), and patient-reported outcomes (questionnaires for daytime sleepiness, fatigue, diabetes distress, and depressive mood) were completed at baseline and at completion of the intervention. Results: Sleep-Opt-In was feasible and acceptable. Those in Sleep-Opt-In with objectively confirmed short or irregular sleep demonstrated an improvement in sleep regularity (25 minutes), reduced glycemic variability (3.2%), and improved time in range (6.9%) compared to the Healthy Living attention control group. Patient-reported outcomes improved only for the Sleep-Opt-In group. Fatigue and depressive mood improved compared to the control. Conclusions: Sleep-Opt-In is feasible, acceptable, and promising for further evaluation as a means to improve sleep duration or regularity in the population of people with type 1 diabetes.

description: Soft rot caused by Pectobacterium sp. is responsible for significant losses in vegetable production worldwide. Methods for the effective control of soft rot are limited and primarily based on good agricultural practices. The use of bacteriophages as biocontrol agents appears to be a promising alternative to combat phytopathogens. In this study, we investigated the efficacy of lytic phages recovered from symptomatic cabbage tissues and environmental samples against soft rot caused by Pectobacterium carotovorum subsp. carotovorum. Three bacteriophage isolates, designated as vB_PcaP-A3, vB_PcaM-D1, and vB_PcaM-J3, were observed to effectively lyse P. carotovorum subsp. carotovorum. Phage vB_PcaP-A3 exhibited virion morphology similar to the members of the podovirus group, while phages vB_PcaM-D1 and vB_PcaM-J3 showed myovirus morphology based on transmission electron microscopy. The optimal multiplicity of infection (MOI) differed greatly among the three phages. All three phages survived incubations at 30, 40 and 50 °C and pH conditions ranging from 3.0 to 9.0, but were all inactivated at 60°C and at pH 12. Both monophage and cocktail preparations were effective in inhibiting the growth of P. carotovorum subsp. carotovorum in the in vitro challenge tests. In the potato slice assays, while treatment with cocktail preparations completely inhibited the development of soft rot in tissue slices, monophage treatments not only resulted in a significant reduction of tissue maceration in slices, but also showed protective effect against soft rot in tubers. Overall, these results demonstrate the efficacy of phages vB_PcaP-A3, vB_PcaM-D1, and vB_PcaM-J3 for the biocontrol of soft rot caused by P. carotovorum subsp. carotovorum.

description: There are a number of tasks in quantum information science that exploit non-transitional adiabatic dynamics. Such a dynamics is bounded by the adiabatic theorem, which naturally imposes a speed limit in the evolution of quantum systems. Here, we investigate an approach for quantum state engineering exploiting a shortcut to the adiabatic evolution, which is based on rapid quenches in a continuous-time Hamiltonian evolution. In particular, this procedure is able to provide state preparation faster than the adiabatic brachistochrone. Remarkably, the evolution time in this approach is shown to be ultimately limited by its "thermodynamical cost,"provided in terms of the average work rate (average power) of the quench process. We illustrate this result in a scenario that can be experimentally implemented in a nuclear magnetic resonance setup.

description: Recent $μ$SR measurements on SrPtAs revealed time-reversal-symmetry breaking with the onset of superconductivity [Biswas et al., Phys. Rev. B 87, 180503(R) (2013)], suggesting an unconventional superconducting state. We investigate this possibility via functional renormalization group and find a chiral $(d+\mathrm{i}d)$-wave order parameter favored by the multiband fermiology and hexagonal symmetry of SrPtAs. This $(d+\mathrm{i}d)$-wave state exhibits significant gap anisotropies as well as gap differences on the different bands, but only has point nodes on one of the bands at the Brillouin zone corners. We study the topological characteristics of this superconducting phase, which features Majorana-Weyl nodes in the bulk, protected surface states, and an associated thermal Hall response. The lack of extended nodes and the spontaneously broken time-reversal symmetry of the $(d+\mathrm{i}d)$-wave state are in agreement with the $μ$SR experiments. Our theoretical findings together with the experimental evidence thus suggests that SrPtAs is the first example of chiral $d$-wave superconductivity.

description: This dissertation reports the measurement of the branching fractions of neutral and charged B meson decays to final states containing a K_1(1270) or K_1(1400) meson and a charged pion. The data, collected with the BaBar detector at the SLAC National Accelerator Laboratory, correspond to 454 million B Bbar pairs produced in e+ e- annihilation. We use the results to estimate the weak phase alpha from the time dependent CP asymmetries in B0 --> a_1(1260)+/- pi-/+ decays.
title: Protracted international conflicts in South Asia: the route to intractability in the Kashmir conflict 1947-1990
Creators: name: Khan, Abdur Rob
Publisher: name: University of Kent
Year: 2023

description: The central concern of the thesis is a detailed analysis of protracted international conflicts (PICs) in a bid to explain how and why certain international conflicts become intractable. The manner in which a conflict becomes protracted is a fundamental question that confronts any analyst of contemporary international conflicts. Is protractedness a property of particular sorts of conflicts or is it associated with specific types of actors in a conflict? Is it a concatenation of such dimensions? Or is protractedness a product of circumstances? Moreover, protractedness may be latent, if so, it is necessary to study the actual and potential triggers that lead to a protracted state of conflict. In short, the nature of protracted conflicts has been ill-defined. It is the purpose of the thesis to develop a sharper definition of PIC and elucidate its causes, patterns and underlying processes. The present thesis has been developed in the specific context of South Asia through a case study of the Kashmir conflict, 1947-1990. In explaining the route to intractability of the conflict, specific attention has been paid to its origin in 1947 over the status of the Princely state of Kashmir, its persistence and linkage with other issues and conflicts, and its occasional flare ups in military hostilities and violence, including its latest transformation into a secessionist insurgency supplanting the inter-state conflict. The origin of a conflict has been viewed in the thesis as an outcome of a complex process of linkages and polarisation in which other conflicts, issues and actors coalesce over a salient issue. The salient issue itself may be an outcome of a prior conflictual process. Left to itself, the conflict coagulates internally and, at the same time, links up with other issues or conflicts to become intractable and resistant to resolution. The conflict may also transform itself as new issues and parties are added to the old dispute. In short, it develops a life of its own.

description: Optical imaging provides critical spatial data and context for the vast network of different cell types and anatomical structures present in the human body. One such approach, highly multiplexed antibody-based imaging, targets protein biomarkers in situ using dozens of antibodies, allowing for the comprehensive profiling of cell states and phenotypes at single cell resolution within normal and diseased tissues. Beyond preserving cell-cell interactions and tissue architecture, this approach offers insight into the cellular morphology and multi-scale spatial patterns of cells within complex tissues. This technique also permits assessment of cell state using probes for post-translationally modified molecules generated by active signaling events or by imaging of nuclear localization of transcription factors. When coupled to advanced analytical methods, high content imaging allows for the quantification of rare and difficult to extract cell types such as tissue-resident macrophages and fibroblasts. While these methods may vary in format (fluorophore-, metal-, or oligo-conjugated), mode of imaging (all-in-one or cyclic), or mode of immunolabeling (all-in-one or cyclic), all employ antibodies for protein biomarker detection (Hickey et al. 2021). Given the wealth of information provided by multiplexed antibody-based imaging, these techniques are foundational to international efforts aimed at building a comprehensive human reference atlas (HRA) (Snyder et al. 2019; Regev et al. 2017).

description: We present genuine bulk Ir 5d jeff states of layered perovskite iridates obtained by hard-x-ray photoemission spectroscopy (HAXPES) with s- and p-polarized lights. HAXPES spectra of Sr2IrO4 and Ba2IrO4 are well reproduced by the quasi-particle densities of states calculated by the local density approximation with dynamical mean-field theory (LDA+DMFT). It is demonstrated that the insulating nature of the iridates is triggered by antiferromagnetic correlation (Slater type) combined with electron correlation (Mott type). The extremely-low-energy bulk-sensitive photoemission spectroscopy reveals "bad metallic" states in the paramagnetic phase of the iridates, suggesting strongly renormalized metallic states above the Neel temperature as predicted by the LDA+DMFT.

description: In the recent years, electronic devices have become smaller and faster, as well as more powerful and efficient. However, the size of the building blocks of the current electronics - i.e. the transistors - is quickly approaching the limits of manufacture. The need of a new generation of devices based on novel mechanisms is today essential. In this scenario, well-defined interfaces between oxide materials have produced novel electronic systems displaying a spectacular variety of properties with promising potentialities for future devices, such as colossal magnetoresistance, high-temperature superconductivity, magnetism at the interface between non magnetic oxides, as well as two-dimensional electron gas between two oxide insulators. Indeed, interfaces between perovskite oxides - e.g. the LaAlO3/SrTiO3 ? have shown properties at the nanometer scale that are qualitatively different from their single building blocks, allowing one to engineer novel functionalities through the growth of epitaxial heterostructures. Nevertheless, both atomic and electronic reconstructions could be present in oxide interfaces when a polar discontinuity occurs at the junction and the possibility to probe non-destructively the cation depth profiles can provide further insight into the oxide heterointerface physics. This is also true for less-ordered systems - i.e. amorphous thin films - which are playing a key role in the development of new architectures in photovoltaic applications, such as the CdxSnyOz/TiO2 heterojunction. In this Thesis, the combination of chemical and structural information on a local scale (i.e. at the interface and the nearby few atomic layers) has been obtained by combining an effective modeling of angle-resolved x-ray photoemission data, with synchrotron based electron spectroscopy techniques. It is shown how in oxides the interfacial electronic properties can be driven by complex substitutional effects across the interface, such as stoichiometry gradients, cation vacancies and interdiffusion, as well as by the presence of interfacial/surface oxygen vacancies.

LA VOLONT� DI RIFORMA DEI TEATRI MILANESI DURANTE IL PERIODO NAPOLEONICO

description: When Napoleone arrived in Milano, the theatrical performances in the two most popular town theatres, the Scala and the Cannobbiana, were often troubled by frequent disorders: the foyers were engaged by games of chance, in the boxes people hold receptions and the audience frequently encroached the stage and the dressing rooms to dwell with singers and dancers. The new Government saw in the theatre a useful instrument to develop repubblican ideals and for this reason introduced immediately some reforms. The first amendment was the drawing up of a national theatre regulations and then was set up the commission to improve the performances. From 1803 to 1813 Earl Carlo Brentano Grianty managed the whole milanese theatrical production and maintained the good theatrical order.

description: Galaxy masses play a fundamental role in our understanding of structure formation models. This review addresses the variety and reliability of mass estimators that pertain to stars, gas, and dark matter. The different sections on masses from stellar populations, dynamical masses of gas-rich and gas-poor galaxies, with some attention paid to our Milky Way, and masses from weak and strong lensing methods, all provide review material on galaxy masses in a self-consistent manner.

description: Background: Intensive treatment programmes (ITPs) for posttraumatic stress disorder (PTSD) produce large symptom reductions and have generally higher completion rates compared to traditional weekly care. Although ITPs do not appear to increase substance use, it has yet to be determined whether their effectiveness differs for veterans with and without hazardous alcohol use (HAU). Objective: This study examined the effectiveness of a 3-week Cognitive Processing Therapy-based ITP for 538 veterans with PTSD (66.0% male; mean age = 41.22 years) and with (n = 193) or without HAU (n = 343) for reducing PTSD and depression symptoms. Method: Veterans' PTSD (PCL-5) and depression (PHQ-9) symptoms were assessed at pre-treatment, during treatment, and at post-treatment. HAU (AUDIT-C total score ≥4 for males; ≥3 for females) was measured at intake. Results: Treatment completion rates were high for both individuals who endorsed HAU (92.68%) and those who did not (93.37%), likely due to veterans being housed near the treatment facility. Mixed effects regression models revealed a significant time by alcohol use interaction when predicting both PCL-5 (p < .001) and PHQ-9 (p = .003), suggesting time-trends over the course of the ITP differed based on alcohol use. Veterans who endorsed HAU improved to a statistically significantly lesser extent. However, endpoint differences between groups for both outcomes were small (Cohen's ds between 0.15 and 0.20). Conclusions: Veterans with and without HAU reported significant reductions in PTSD and depression symptoms and completed the ITP at comparably high rates. Findings support the effectiveness of intensive PTSD treatment programmes for individuals with PTSD and HAU. Future studies should utilize controlled designs to evaluate whether intensive PTSD treatment can reduce HAU.
RIGIDITY RESULTS FOR LICHNEROWICZ BAKRY-EMERY RICCI TENSORS
Creators: name: RIMOLDI, MICHELE

description: We investigate rigidity phenomena in the class of Riemannian manifolds with density. By a weighted manifold (or manifold with density) we mean a Riemannian manifold endowed with a weighted measure absolute continuous with respect to the Riemannian one. Associated to a weighted manifold there is also a natural divergence form second order diffusion operator: the f-Laplacian. Good choiches for the concept of curvature in this setting are those that reveal interplays with metric and topological properties of the space. We have focused on Lichnerowicz Bakry-Emery Ricci's tensors. When we impose the constancy of these tensors we are endowing the manifold of an additional structure, namely, a gradient Ricci soliton or a quasi-Einstein structure. The importance of Ricci solitons is due to Perelman's solution of Poincar� conjecture, while the importance of quasi-Einstein manifolds comes from the relationship they have with Einstein warped products. Actually in this thesis we also introduce an extension of the concept of gradient Ricci soliton, the Ricci almost soliton, allowing the soliton constant to be a generic smooth function on the weighted manifold. In view of the not necessarily constantness, one expects that a certain flexibility on the almost soliton structure is allowed and, consequently, the existence of almost solitons is easier to prove than in the classical situation. This feeling is confirmed by a number of diff erent examples of almost solitons. On the other hand we prove a rigidity result which indicates that almost solitons should reveal a reasonably broad generalization of the fruitful concept of classical soliton. Considering elliptic equations and inequalities (naturally involving the f-Laplacian) for various geometric quantities and making use of analytical techniques coming from stochastic analysis such as stochastic completeness, in the form of the weak Omori-Yau maximum principle, parabolicity and Lp-Liouville type results, we prove rigidity in the form of metric rigidity (scalar curvature estimates, classification results, gap theorems for some geometric quantities) and in the form of triviality of the additional structure. Moreover we obtain also topological rigidity for these tensors (with consequences e.g. on the structure of the fundamental group).

Creators: name: Ehrlicher, Hanno

description: Despite the belief that Spanish literature during the Counterreformation functioned as propaganda in service to the traditional idea of the pilgrimage, this article examines a body of texts from the latter half of the sixteenth century, and demonstrates that they functioned in the liminal space between the profane and the sacred. Within this space, the tensions between secularity and spirituality were fought out, leading to complex and often bewildering hybrid texts. Bartholomé de Villalba’s unpublished Peregrini curioso shows both a secularization of the pilgrimage concept and an ostentatious affirmation of Spain as a harbor of Catholic piety. Jerónimo de Contreras’ Selva de Aventuras recasts the pilgrimage idea as a love interest, and presents marriage and the renunciation of marriage as competing suggestions. Fernão Mendes Pinto’s Peregrinação can be read either as the hagiography of St. Francis Xavier, or as criticism of a completely irremediable practice of piratical colonization.

description: Effective interactions can be obtained from a renormalization group analysis in two complementary ways. One can either explicitly integrate out higher energy modes or impose given conditions at low energies for a cut-off theory. While the first method is numerically involved, the second one can be solved almost analytically. In both cases we compare the out coming effective interactions for the two nucleon system as functions of the cut-off scale and find a strikingly wide energy region where both approaches overlap, corresponding to relevant scales in light nuclei about 200MeV. This amounts to a great simplification in the determination of the effective interaction parameters.

description: This thesis introduces and studies the problem of 1-dimensional bounded clustering: for any fixed p ? 1, given reals x1, x2?, xn, and integers k1, k2.., km, determine the partition (A1, A2? Am) of {1, 2, ..., n} with |A1| = k1, |A2| = k2 , ? , |Am| = km which minimizes ?k ?i? Ak |xi - ?k |p where ?k is the p-centroid of Ak First, we prove that the optimum partition is contiguous (String Property), that is if i,j ? Ak, and xi < xs < xj, then s ? Ak . As a consequence, we determine an efficient algorithm for bi-clustering (if p is an integer); however, we show that the general problem is NP-complete, while a relaxed version of it admits a polynomial-time algorithm. When p is not an integer, we prove that the problem of deciding if the centroid ? is less than a given integer is in the Counting Hierarchy CH. As an application, the relaxed clustering algorithm used as a step for solving a problem in the field of Bioinformatics: the Localization of promoter regions in genomic sequences. The results are compared with those obtained through another methodology (MADAP).
