description: We investigate the strong influence of the $Θ_{II}$-loop-current order on both unidirectional and bidirectional d-wave charge-density-wave/pair-density-wave (CDW/PDW) composite orders along axial momenta $(\pm Q_0,0)$ and $(0,\pm Q_0)$ that emerge in an effective hot spot model departing from the three-band Emery model relevant to the phenomenology of the cuprate superconductors. This study is motivated by the compelling evidence that the $Θ_{II}$-loop-current order described by this model may explain groundbreaking experiments such as spin-polarized neutron scattering performed in these materials. Here, we demonstrate, within a saddle-point approximation, that the $Θ_{II}$-loop-current order clearly coexists with bidirectional (i.e. checkerboard) d-wave CDW and PDW orders along axial momenta, but is visibly detrimental to the unidirectional (i.e. stripe) case. This result has potentially far-reaching implications for the physics of the cuprates and agrees well with very recent x-ray experiments on YBCO that indicate that at higher dopings the CDW order has indeed a tendency to be bidirectional.

Corner Store Strategies: Innovative Approaches to Addressing Economic and Public Health in Rural North Carolina
Creators: name: Walter, Melissa

Year: 2016

description: More than 29 million Americans live in food deserts. The growing prevalence of food deserts contributes to the epidemics of obesity and chronic disease. Despite this, no state legislation has been identified that has directly funded healthy food retail in corner stores—stores which often cannot stock produce or nutrient-dense foods due to their lack of costly refrigeration equipment. With more than twice as many corner stores in food deserts than in high-income areas, this represents a missed opportunity. In 2016, the North Carolina General Assembly enacted and funded innovative legislation to address the challenge of food access in food deserts through an appropriation to supply refrigeration and food stocking equipment to corner stores. The NC Department of Agriculture was tasked with the development and implementation of this Healthy Food Small Retailer Program (HFSRP). The HFSRP is layering multiple “no-cost” intervention strategies with its equipment initiative to address both economic and public health issues in NC food deserts and to provide a more solid foundation for sustainability.

description: Cette thèse de doctorat est consacrée à la pensée du philosophe américain Nelson Goodman (1906-1998). Nous y défendons, à l’encontre de la plus grande partie de la critique, une lecture métaphysicienne de son œuvre. Il est démontré que Goodman, dans tous ses travaux, développe une métaphysique technique et méconnue, dont les piliers sont le nominalisme, le pluralisme, le perdurantisme, l’actualisme, et l’universalisme méréologique. Cette lecture permet de réévaluer l’ensemble de la pensée goodmanienne. Elle établit aussi ses liens insoupçonnés avec la métaphysique analytique contemporaine.

A Proposed Intervention Strategy to Reduce and Prevent the Increase of Obesity in the Galápagos Islands-Ecuador
Creators: name: Ocampo, Maria Belen
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Introduction: Overweight and obesity are health conditions characterized by excessive accumulation of fat as a result of an imbalance between energy intake and expense. The current health and nutrition situation in Ecuador reflects the epidemiologic and nutritional transition characteristic of middle-income countries, which consists on a rapid increase in the incidence of overweight and obesity, while cases of under nutrition still exist. Because of specific characteristics of this territory, the prevalence of obesity and overweight is higher than in any other region of the country. Methods: A literature review, visit to the island and application of NEMCS-CS questionnaire allowed for a better qualification of the current food and nutrition situation in the islands, and to guide the development of a public health intervention. Results: Corner stores showed a low availability of natural foods, and higher stock of ultra-processed foods; weekly farmer’s market has higher offer of natural foods, but individuals find both the schedule and the prices to be inconvenient; CIBV public nurseries provide meals for children and carry out twice-yearly nutrition evaluation, however there is no technical nutritional guidance; The built environment in the island is conducive to physical activity, however people do not use these spaces. Development of a multicomponent intervention including a campaign to raise awareness of the nutritional situation in the islands, implementation of a neighborhood stores initiatives to increase availability of fresh produce, and the use of telemedicine to provide nutritional counseling, accompanied by periodic visits of nutrition professionals to the islands. Limitations: The length of the visit to the islands and the small sample of interviews collected allowed for important information on lifestyle to be gathered, it would be necessary to go back and collect even more information from other sources to make sure the proposed intervention will be successful.
Tackling Islamic radicalisation in Kyrgyzstan: a role for the OSCE?

description: Second semester University: University of Hamburg.
description: The popularity of radical Islamic groups such as Hizb ut-Tahrir is rising in Kyrgyzstan, yet an appropriate policy for dealing with it is yet to emerge. The approach to date taken by the government has been characterised by authoritarianism, abuse of human rights and a reliance on the security services. This approach is not working. This thesis will examine how the OSCE could support the Kyrgyz government in designing and implementing an appropriate response to Islamic radicalism. This will be done by constructing an analytical framework from conflict prevention theories to examine the causes of radicalism and potential instruments to remedy it, comparing these instruments with the conflict prevention and counter-radicalisation tools of the OSCE.

description: We use the phase plane analysis technique of Madsen and Ellis to consider a universe with a true cosmological constant as well as a cosmological "constant" that is decaying. Time symmetric dynamics for the inflationary era allows eternally bouncing models to occur. Allowing for scalar field dynamic evolution, we find that if dark energy decays in the future, chaotic cyclic universes exist provided the spatial curvature is positive. This is particularly interesting in light of current observations which do not yet rule out either closed universes or possible evolution of the cosmological constant. We present only a proof of principle, with no definite claim on the physical mechanism required for the present dark energy to decay.

Correlation Between Quality of Life, Nutrition Status, and Disease Stage Among Pancreatic and Periampullary Cancer Patients
Creators: name: Lowe, Sarah

Year: 2014

description: Importance: Nutrition status and quality of life (QOL) have been previously correlated in patients with various types of cancers, yet the relationship in pre-treatment pancreatic and periampullary cancer patients remains unknown. Objectives: To determine whether there is an association between pre-treatment nutrition status and QOL, and if either variable is correlated with disease stage. Design, Setting, and Participants: This cross-sectional observational analysis included 110 treatment-naïve patients who presented to The University of Texas MD Anderson Cancer Center (MDACC) for initial surgical evaluation and/or treatment for localized pancreatic cancer or periampullary neoplasm between September 2009 and March 2013. These subjects were part of a larger longitudinal study (“Correlative Study of Nutrition and Quality of Life in Patients with Pancreatic Cancer”), and were selected based on disease staging availability and diagnosis of adenocarcinoma or neuroendocrine tumor of the pancreas or periampullary region. Main Outcome Measures: Nutrition status was measured using the Patient-Generated Subjective Global Assessment (PG-SGA) questionnaire. QOL was assessed using the Functional Assessment of Cancer Therapy-Hepatobiliary (FACT-Hep) questionnaire. Disease stage was quantified using the American Joint Commission on Cancer (AJCC) and International Union for Cancer Control (IUCC) “TNM” staging guidelines. Results: PG-SGA scores were significantly negatively associated with total FACT-Hep score (P< 0.001), Physical Well-being (PWB) subscore (P< 0.001), Functional Well-being (FWB) subscore (P< 0.001), and Hepatobiliary (Hep) subscore (P< 0.001). AJCC disease stage was significantly positively associated with PG-SGA score (P=0.004) and significantly negatively associated with total FACT-Hep score (P=0.05), PWB subscore (P=0.02), and Hep subscore (P=0.02). Thus, those subjects with more advanced disease stage tended to have a poorer nutrition status and poorer QOL. Hyperlipidemia/hypercholesterolemia (OR=14.67, P= 0.001), histologic diagnosis (neuroendocrine tumor vs. adenocarcinoma) (OR= 0.19, P= 0.02), and PGSGA score (OR= 1.13, P= 0.004) were found to be significant predictors of AJCC disease stage. Conclusion and Relevance: Pre-treatment nutrition status is significantly correlated with QOL, and both nutrition status and QOL are significantly associated with AJCC disease stage in patients with pancreatic or periampullary cancer. These factors should be taken into consideration when making plan of care decisions to maximize patient QOL during and after treatment.

description: Es gibt gute Gründe anzunehmen, dass Jugendliche mit geringer Selbstkontrolle bestimmte Routineaktivitäten verfolgen, welche sie in Situation bringen, in denen sie häufiger sowohl Opfer als auch Täter von Straftaten werden. Basierend auf der General Theory of Crime (Gottfredson/ Hirschi 1990) und der Routine Activities Theory (u. a. von Cohen/Felson 1979), analysiert das vorliegende Working Paper Prädiktoren für den Offending-Victimization-Overlap in einem Sample von 12- bis 16-jährigen Schülern anhand der Daten der zweiten Welle der International Self-Report Delinquency Studies (ISRD-2). Die wichtigsten Variablen sind Selbstkontrolle und ein riskanter Lebensstil sowie die Prävalenzraten von drei Straftaten (Körperverletzung, Raub und Diebstahl). Bivariate Probitmodelle sprechen für eine Kombination der General Theory of Crime und der Routine Activities Theory. In verschiedenen Modellen, welche auf die Annahmen aus beiden Theorien gestützt sind, zeigt sich, dass die stärksten Effekte, welche zu Viktimisierung und Delinquenz führen, von geringer Selbstkontrolle und einem riskanten Lebensstil (mit delinquenten Freunden, Alkohol- und Drogenkonsum, Zeit auf öffentlichen Plätzen mit einer großen Freundesgruppe und ein Mangel an Freizeitaktivitäten mit den Eltern) stammt. Die Schlussfolgerungen aus den Ergebnissen werden ebenso diskutiert wie die Einschränkungen der Studie und zukünftige Forschungsrichtungen.

description: We propose a new concept for spectral characterization of transiting exoplanets with future space-based telescopes. This concept, called as densified pupil spectroscopy, allows us to perform high, stable spectrophotometry against telescope pointing jitter and deformation of the primary mirror. This densified pupil spectrometer comprises the following three roles: division of a pupil into a number of sub-pupils, densification of each sub-pupil, and acquisition of the spectrum of each sub-pupil with a conventional spectrometer. Focusing on the fact that the divided and densified sub-pupil can be treated as a point source, we discovered that a simplified spectrometer allows us to acquire the spectra of the densified sub-pupils on the detector plane-an optical conjugate with the primary mirror-by putting the divided and densified sub-pupils on the entrance slit of the spectrometer. The acquired multiple spectra are not principally moved on the detector against low-order aberrations such as the telescope pointing jitter and any deformation of the primary mirror. The reliability of the observation result is also increased by statistically treating them. Our numerical calculations show that, because this method suppresses the instrumental systematic errors down to 10 ppm under telescopes with modest pointing accuracy, next-generation space telescopes with more than 2.5m diameter potentially provide opportunities to characterize temperate super-Earths around nearby late-type stars through the transmission spectroscopy and secondary eclipse.

Development and Testing of a Simple Assessment Framework to Improve Multicomponent Interventions Promoting Fruit and Vegetable Consumption
Creators: name: Chapman, William
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: Poverty and food insecurity are socio-economic factors which increase the risk of developing lifestyle-related chronic disease. Racial and ethnic minorities are more likely to be affected by these factors than white, non-Hispanic individuals. Numerous interventions have tried to improve diet quality and overall health in low-income and minority populations, but many focus on only a single driver of behavior such as education, access, or affordability, rather than addressing all constraining factors simultaneously. Four primary elements drive nutrition-related behaviors: knowledge, instruments, skills, and materials (KISM). This proposed framework offers a simple, theory-based tool for tailoring nutrition interventions by identifying the community- and population-specific drivers of health behavior. Knowledge determines an individuals’ level of interest in performing a behavior. Instruments enable the performance of the behavior, while Skills determine the ability of a given individual to translate knowledge into action. Materials are tangible resources consumed during the performance of the behavior. This framework enables both professional and lay audiences to easily understand the interaction between intervention components, making it ideal for community-based participatory research in areas with low health literacy. The KISM framework is currently being used to inform the development of a multicomponent intervention to increase fruit and vegetable consumption among low-income African Americans in Eastern North Carolina. The intervention will be a collaborative effort between the Coalition for Healthier Eating, local faith-based institutions, and churches.

A Novel Visualization of the Geometry of Special Relativity

Year: 2015
Subjects: subject: Classical Physics (physics.class-ph)
subject: FOS: Physical sciences

description: The mathematical treatment and graphical representation of Special Relativity (SR) are well established, yet carry deep implications that remain hard to visualize. This paper presents a new graphical interpretation of the geometry of SR that may, by complementing the standard works, aid the understanding of SR and its fundamental principles in a more intuitive way. From the axiom that the velocity of light remains constant to any inertial observer, the geodesic is presented as a line of constant angle on the complex plane across a set of diverging reference frames. The resultant curve is a logarithmic spiral, and this view of the geodesic is extended to illustrate the relativistic Doppler effect, time dilation, length contraction, the twin paradox, and relativistic radar distance in an original way, whilst retaining the essential mathematical relationships of SR. Using a computer-generated graphical representation of photon trajectories allows a visual comparison between the relativistic relationships and their classical counterparts, to visualize the consequences of SR as velocities become relativistic. The model may readily be extended to other situations, and may be found useful in presenting a fresh understanding of SR through geometric visualization.

Dies verweist auf die Frage nach den gesellschaftlichen Bewertungskriterien für Arbeit und Berufe. Deren soziale und normative Grundlagen werden nicht erst seit Beginn der Corona-Pandemie infrage gestellt. Damit dürfte die Pandemie auch Debatten und Auseinandersetzungen um Normen wie soziale Gerechtigkeit, Leistung, Solidarität oder gesellschaftlichen Zusammenhalt befördern. Wie die betreffenden Arbeitnehmerinnen und Arbeitnehmer auf ihre Erfahrungen mit dieser Entwicklung reagieren, welche Erwartungen zur Aufwertung systemrelevanter Berufe aus der Verarbeitung coronabedingter Krisenerfahrungen resultieren und welche Spielräume für spezifische Aufwertungsstrategien gesehen werden, wird – differenziert nach Berufsgruppen und Arbeitsfeldern – analysiert.

Im Mittelpunkt dieses Projekts steht die Analyse der sozialen Interaktionen zwischen Stadtbewohnern aus sozialräumlicher Perspektive. Zur Vorbereitung einer Analyse der sozialen Mechanismen, die zwischen räumlichen Merkmalen und der sozialen Interaktion bzw. dem sozialen Handeln vermitteln, widmet sich der vorliegende Beitrag einer Sozialraumanalyse in der Tradition der Chicago School der Soziologie. Hierzu werden administrativ definierte räumliche Einheiten einer ostdeutschen Großstadt anhand von Daten der amtlichen Statistik beschrieben und einer Klassifikationsanalyse unterzogen. Eine Hauptkomponentenanalyse und verschiedene Verfahren der deterministischen Clusteranalyse (Single-Linkage, Ward, Complete Linkage, K-Means) führen zu dem Ergebnis, dass die räumlichen Einheiten entlang von zwei Dimensionen voneinander unterschieden werden können, nämlich der strukturellen Desorganisation und der kulturellen Heterogenität.
Device-independent test of causal order and relations to fixed-points

Publisher: name: arXiv
Year: 2015
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Bell non-local correlations cannot be naturally explained in a fixed causal structure. This serves as a motivation for considering models where no global assumption is made beyond logical consistency. The assumption of a fixed causal order between a set of parties, together with free randomness, implies device-independent inequalities --- just as the assumption of locality does. It is known that local validity of quantum theory is consistent with violating such inequalities. Moreover, for three parties or more, even the (stronger) assumption of local classical probability theory plus logical consistency allows for violating causal inequalities. Here, we show that a classical environment (with which the parties interact), possibly containing loops, is logically consistent if and only if whatever the involved parties do, there is exactly one fixed-point, the latter being representable as a mixture of deterministic fixed-points. We further show that the non-causal view allows for a model of computation strictly more powerful than computation in a world of fixed causal orders.

The use of blenderized tube feeding in pediatric patients: evidence and guidelines for dietetic practice
Creators: name: Schoenfeld, Laura
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2013

description: Blenderized tube feedings, or the provision of food that has been pureed using a blender through a patient’s feeding tube, is a practice that has recently been gaining in popularity despite the availability of commercially prepared, nutritionally complete formulas. While many health professionals may prefer to use the chemically defined formulas that have been prepared to maximize safety and provide appropriate nutrition to a variety of patients, there has been an increase in patient interest in the use of blenderized tube feeds, particularly in pediatric patients. As reliance on the internet as a source of family health solutions increases, more parents are discovering and requesting the use of blenderized diets for a variety of reasons, including a growing interest in natural foods for their child’s diet. With books such as The Homemade Blended Formula Handbook, and websites such as www.foodfortubies.com, it is clear that interest in this feeding method will continue to increase over the next few years. Further, the use of blenderized tube feedings may actually provide benefits to some patients, and may be advantageous over the use of commercial preparations in certain populations. Anecdotal reports of clinical improvement in children whose parents have decided to make the switch are numerous and detail parental and clinician observations of improved outcomes. Thus, it would improve the safety and efficacy of this treatment if dietitians were able to develop nutritionally adequate blenderized diets and appropriately monitor the pediatric patients whose parents choose to use them. The purpose of this paper is to provide a comprehensive review of the use of blenderized tube feeds in pediatric populations and to describe the currently available evidence supporting its use in specific patient populations. This paper will describe the advantages and disadvantages of the blenderized diet, define key parameters in determining the appropriate candidates for blenderized tube feeds, and develop nutritionally complete recipes for use with patients who have been approved for the transition to a blenderized diet. As interest in this technique is likely to grow in the coming years, it is critical for dietitians to understand why and how a blenderized diet should be used in order to guide interested patients in a safe and effective way.

Background field method and the cohomology of renormalization

Subjects: subject: High Energy Physics - Theory (hep-th)

description: Using the background field method and the Batalin-Vilkovisky formalism, we prove a key theorem on the cohomology of perturbatively local functionals of arbitrary ghost numbers, in renormalizable and nonrenormalizable quantum field theories whose gauge symmetries are general covariance, local Lorentz symmetry, non-Abelian Yang-Mills symmetries and Abelian gauge symmetries. Interpolating between the background field approach and the usual, nonbackground approach by means of a canonical transformation, we take advantage of the properties of both approaches and prove that a closed functional is the sum of an exact functional plus a functional that depends only on the physical fields and possibly the ghosts. The assumptions of the theorem are the mathematical versions of general properties that characterize the counterterms and the local contributions to the potential anomalies. This makes the outcome a theorem on the cohomology of renormalization, rather than the whole local cohomology. The result supersedes numerous involved arguments that are available in the literature.

description: Advances in unsupervised learning and deep neural networks have led to increased performance in a number of domains, and to the ability to draw strong comparisons between the biological method of self-organization conducted by the brain and computational mechanisms. This thesis aims to use real-world data to tackle two areas in the domain of computer vision which have biological equivalents: feature detection and motion tracking. The aforementioned advances have allowed efficient learning of feature representations directly from large sets of unlabeled data instead of using traditional handcrafted features. The first part of this thesis evaluates such representations by comparing regularization and preprocessing methods which incorporate local neighbouring information during training on a single-layer neural network. The networks are trained and tested on the Hollywood2 video dataset, as well as the static CIFAR-10, STL-10, COIL-100, and MNIST image datasets. The induction of topography or simple image blurring via Gaussian filters during training produces better discriminative features as evidenced by the consistent and notable increase in classification results that they produce. In the visual domain, invariant features are desirable such that objects can be classified despite transformations. It is found that most of the compared methods produce more invariant features, however, classification accuracy does not correlate to invariance. The second, and paramount, contribution of this thesis is a biologically-inspired model to explain the emergence of motion tracking behaviour in early development using unsupervised learning. The model’s self-organization is biased by an original concept called retinal constancy, which measures how similar visual contents are between successive frames. In the proposed two-layer deep network, when exposed to real-world video, the first layer learns to encode visual motion, and the second layer learns to relate that motion to gaze movements, which it perceives and creates through bi-directional nodes. This is unique because it uses general machine learning algorithms, and their inherent generative properties, to learn from real-world data. It also implements a biological theory and learns in a fully unsupervised manner. An analysis of its parameters and limitations is conducted, and its tracking performance is evaluated. Results show that this model is able to successfully follow targets in real-world video, despite being trained without supervision on real-world video.

description: Modern proposed atmospheric neutrino oscillation experiments, such as PINGU in the Antarctic ice or ORCA in Mediterranean sea water, aim for precision measurements of the oscillation parameters including the ordering of the neutrino masses. They can, however, go far beyond that: Since neutrino oscillations are affected by the coherent forward scattering with matter, neutrinos can provide a new view on the interior of the earth. We show that the proposed atmospheric oscillation experiments can measure the lower mantle density of the earth with a precision at the level of a few percent, including the uncertainties of the oscillation parameters and correlations among different density layers. While the earth's core is, in principle, accessible by the angular resolution, new technology would be required to extract degeneracy-free information.

A Business Plan for a Nutrition Private Practice Specializing in Food Allergies and Celiac Disease
Creators: name: Kennedy, Julie
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Food allergies and celiac disease are increasingly becoming a public health problem that affects both children and adults.  Research studies estimate that over 15 million Americans have a food allergy and about 3.2 million Americans have celiac disease. (11,12) While both celiac disease and food allergies have only one single treatment option of avoiding the trigger food, they are not the same conditions.  Food allergies develop through a genetic and/or environmental trigger, which creates an IgE mediated reaction.  When the allergen is ingested, the patient can experience either small reactions, such as an itchy throat, or a more severe reaction, such as life-threatening anaphylaxis.  Like food allergies, celiac disease develops from a genetic and/or environmental trigger, but an autoimmune response occurs when gluten, the protein found in wheat, barley, malt, and rye, is ingested. When even the smallest crumb of a gluten-containing food is consumed, damage to the intestinal villi occurs resulting in a variety of possible symptoms ranging from gastrointestinal issues to brain fog and joint pain.    People affected by both food allergies and celiac disease often receive their diagnosis during a health care visit, and then are left alone to navigate a brand-new diet on their own.  This was the case for my eight-year-old daughter and me when we received our life-altering celiac diagnosis several years ago.  At diagnosis, we were told to go on a gluten free diet, given a short handout, and then asked to come back in six months.  We were not given any detailed instructions, sample meal plans, or any type of nutritional support.  We were confused and overwhelmed, and I do not believe we are the only ones that have had this experience.  Within the healthcare community, there is not sufficient time or resources to give to food allergy and celiac disease patients the in-depth support and encouragement they need, and often patients are left feeling the same way as my daughter and I did.  It was through this experience of feeling lost and confused where the idea of Julie Kennedy Nutrition began.  To adequately navigate the gluten free diet, people need ongoing support including tips for avoiding nutritional potential deficiencies, grocery shopping, eating out, eating during the holidays, sending children to camp or school, and the list goes on.  The goal of my nutrition counseling private practice is to fill this gap between a food allergy or celiac disease diagnosis and a reasonable plan for management. Through this business, I will offer the services patients need to cope with these life-changing realities, the services that my daughter and I desperately needed when we were diagnosed.
Optimization of Modulation Constrained Digital Transmission Systems

Optimal power allocation

description: The regular waterfilling(WF) policy maximizes the mutual information of parallel channels, when the inputs are Gaussian. However, Gaussian input is ideal, which does not exist in reality. Discrete constellations are usually used instead, such as $ M $-PAM and $ M $-QAM. As a result, the mercury/waterfilling (MWF) policy is introduced, which is a generalization of the regular WF. The MWF applies to inputs with arbitrary distributions, while the regular WF only applies to Gaussian inputs. The MWF-based optimal power allocation (OPA) is presented, for which an algorithm called the internal/external bisection method is introduced. The constellation-constrained capacity is discussed in the thesis, where explicit expressions are presented. The expression contains an integral, which does not have a closed-form solution. However, it can be evaluated via the Monte Carlo method. An approximation of the constellation-constrained capacity based on the sphere packing method is introduced, whose OPA is a convex optimization problem. The CVX was used initially, but it did not generate satisfactory results. Therefore, the bisection method is used instead. Capacities of the MWF and its sphere packing approximation are evaluated for various cases, and compared with each other. It turns out the sphere packing approximation has similar performances to the MWF, which validates the approximation. Unlike the MWF, the sphere packing approximation does not suffer from the loss of precision due to the structure of MMSE functions, which demonstrates its robustness.

Some reference formulas for the generating functions of canonical transformations

description: We study some properties of the canonical transformations in classical mechanics and quantum field theory and give a number of practical formulas concerning their generating functions. First, we give a diagrammatic formula for the perturbative expansion of the composition law around the identity map. Then, we propose a standard way to express the generating function of a canonical transformation by means of a certain "componential" map, which obeys the Baker-Campbell-Hausdorff formula. We derive the diagrammatic interpretation of the componential map, work out its relation with the solution of the Hamilton-Jacobi equation and derive its time-ordered version. Finally, we generalize the results to the Batalin-Vilkovisky formalism, where the conjugate variables may have both bosonic and fermionic statistics, and describe applications to quantum field theory.

description: A new singularity free model of anisotroipic compact star is proposed. The Einstein field equations are solved in closed form by utilizing Matese \& Whitman mass function. The model parameters $ρ$, $p_r$ and $p_t$ all are well behaved inside the stellar interior and our model satisfies all the required conditions to be physically acceptable. The model given in the present work is compatible with observational data of compact objects like SAX J 1808.4-3658 (SS1), SAX J 1808.4-3658 (SS2) and 4U 1820-30. A particular model of 4U 1820-30 is studied in detail and found that it satisfies all the condition needed for physically acceptable model. The present work is the generalization of Sharma and Ratanpal\cite{sharma13} model for compact stars admitting quadratic equation of state.
