Abstract:
It is shown that non-local, higher-derivative operators, which arise generically in string field theory, can act as additional sources of friction on the inflaton field as it rolls away from a maximum in its potential. Moreover, the cosmic dynamics can be quantified in terms of a local field theory, where the curvature of an effective potential has been suppressed. A prolonged phase of quasi-exponential expansion can therefore be realised with steep potentials that typically arise in particle physics models. We illustrate this effect within the context of p-adic string theory.

Abstract:
The generation of magnetic fields during the inflation in an electromagnetic model with a non-local form factor in Maxwell’s action is studied. The equations of motion for the electromagnetic field are derived and solved. It is found that the conformal symmetry breaking due to the non-local form factor does not lead to the generation of magnetic fields during the inflation in the absence of an interaction with the inflaton field. If such a coupling takes place, then the presence of the form factor inhibits the generation of primordial magnetic fields compared to the case where the non-local form factor is absent.

Abstract:
Explicit expressions are constructed for a locally conserved vector current associated with a continuous internal symmetry and for energy-momentum and angular-momentum density tensors associated with the Poincaré group in field theories with higher-order derivatives and in non-local field theories. We consider an example of non-local charged scalar field equations with broken C (charge conjugation) and CPT (charge conjugation, parity, and time reversal) symmetries. For this case, we find simple analytical expressions for the conserved currents.

Abstract:
We present the renormalisation group analysis of O(N) invariant scalar field theory in the local potential approximation. Linearising around the Gaussian fixed point, we find the same eigenoperators solutions exist for both the Wilsonian and the Legendre effective actions, given by solutions to Kummer’s equations. We find the usual polynomial eigenoperators and the Hilbert space they define are a natural subset of these solutions given by a specific set of quantised eigenvalues. Allowing for continuous eigenvalues, we find non-polynomial eigenoperator solutions, the so called Halpern-Huang directions, that exist outside of the polynomial Hilbert space due to the exponential field dependence. Carefully analysing the large field behaviour shows that the exponential dependence implies the Legendre effective action does not have a well defined continuum limit. In comparison, flowing towards the infrared we find that the non-polynomial eigenoperators flow into the polynomial Hilbert space. These conclusions are based off RG flow initiated at an arbitrary scale, implying non-polynomial eigenoperators are dependent upon a scale other than k. Therefore, the asymptotic field behaviour forbids self-similar scaling. These results hold when generalised from the Halpern-Huang directions around the Gaussian fixed point to a general fixed point with a general non-polynomial eigenoperator. Legendre transforming to results of the Polchinski equation, we find the flow of the Wilsonian effective action is much better regulated and always fall into the polynomial Hilbert space. For large Wilsonian effective actions, we find that the non-linear terms of the Polchinski equation forbid any non-polynomial field scaling, regardless of the fixed point. These observations lead to the conclusion that only polynomial eigenoperators show the correct, self-similar, scaling behaviour to construct a non-perturbatively renormalisable scalar QFT.

Abstract:
Dans le cadre de la fusion par confinement inertiel, une capsule contenant le combustible de deutérium-tritium est implosée soit par irradiation laser (attaque directe, interaction laser – cible de numéro atomique faible), soit par un rayonnement de corps noir émis par une cavité convertissant le rayonnement laser (attaque indirecte, interaction laser – cible de numéro atomique élevé).Dans les deux cas, une modélisation correcte du transport électronique est cruciale pour avoir des simulations hydro-radiatives prédictives. Cependant, il a été montré très tôt que les hypothèses d'un mécanisme de transport linéaire ne sont pas applicables dans le cadre de l'irradiation d'une cible solide par un laser de puissance (I~10^14 W/cm²). Cela est dû d'une part à des gradients de température très importants (effets cinétiques dits « non-locaux ») ainsi qu'à la présence d'un champ magnétique auto-généré par effet thermo-électrique. Enfin, le flux de chaleur et le champ magnétique sont fortement couplés au travers de deux mécanismes : le transport du champ magnétique par le flux de chaleur (effet Nernst) et la rotation et inhibition du flux de chaleur par la magnétisation du plasma (effet Righi-Leduc).Dans le présent manuscrit, nous commencerons par exposer les différents modèles de transport électronique, et en particulier le modèle non-local avec champ magnétique, implémenté dans le code hydro-radiatif FCI2. Par la suite, nous chercherons à valider ce modèle par des comparaisons avec un code cinétique, puis avec une expérience lors de laquelle le champ magnétique a été mesuré par radiographie proton. Cela fait, nous utiliserons le code FCI2 pour expliquer la source et le transport du champ, ainsi que son effet sur l'interaction.Enfin, nous étudierons la reconnexion du champ magnétique, lors de l'irradiation d'une cible par deux faisceaux lasers<br>In the framework of the inertial confinement fusion, a pellet filled with the deuterium-tritium fuel is imploded, either through laser irradiation (direct drive, laser – low atomic number target interaction) or by the black body radiation from a cavity converting the laser radiation (indirect drive, laser – high atomic number target interaction).In both cases, a correct modeling of the electron transport is of first importance in order to have predictive hydro-radiative simulations. Nonetheless, it has been shown early on that the hypothesis of the linear transport are not valid in the framework of a solid target irradiated by a high power laser (I~1014 W/cm²). This is due in part to very steep temperature gradients (kinetic effects, so-called « non-local ») and because of a magnetic field self-generated through the thermo-electric effect. Finally, the heat flux and the magnetic field are strongly coupled through two mecanisms: the advection of the field with the heat flux (Nernst effect) and the rotation and inhibition of the heat flux by the plasma's magnetization (Righi-Leduc effect).In this manuscript, we will first present the various electron transport models, particularly the non-local with magnetic field model included in the hydro-radiative code FCI2. Following, in order to validate this model, we will compare it first against a kinetic code, and then with an experiment during which the magnetic field has been probed through proton radiography. Once the model validated, we will use FCI2 simulations to explain the source and transport of the field, as well as its effect on the interaction.Finally, the reconnection of the magnetic field, during the irradiation of a solid target by two laser beams, will be studied

Abstract:
In this thesis, we classify up to conjugacy the maximal elliptic toral subgroups of all special orthogonal groups SO(V), where (q,V) is a 4-dimensional quadratic space over a non-archimedean local field of odd residual characteristic. Our parameterization blends the abstract theory of Morris with a generalization of the practical work performed by Kim and Yu for Sp(4). Moreover, we compute an explicit Witt basis for each such torus, thereby enabling its concrete realization as a set of matrices embedded into the group. This work can be used explicitly to construct supercuspidal representations of SO(V).

Abstract:
Le recollement sur les corps, introduit par Harbater et Hartmann, et étendu par ces auteurs et Krashen, a récemment trouvé de nombreuses applications. Nous présentons ici une extension de cette technique au cadre de la géométrie analytique de Berkovich et des applications au principe local-global.Nous montrons que cette adaptation du recollement peut s'appliquer aux courbes analytiques de Berkovich, et par conséquent obtenons des principes locaux-globaux sur les corps de fonctions de courbes définies sur des corps ultramétriques complets. Grâce à la connexion entre les points d'une courbe analytique de Berkovich et les valuations dont on peut munir son corps de fonctions, nous obtenons un principe local-global par rapport à des complétés du corps de fonctions considéré, ce qui présente une ressemblance avec des versions plus classiques. En application, nous établissons des principes locaux-globaux dans le cas plus précis des formes quadratiques et en déduisons des bornes sur l'u-invariant de certains corps. Nos résultats généralisent ceux de Harbater, Hartmann et Krashen.Comme point de départ pour le recollement en dimension supérieure dans un cadre d'espaces de Berkovich, nous montrons que cette technique peut s'appliquer autour de certaines fibres d'une courbe analytique relative. Nous l'utilisons ensuite pour démontrer un principe local-global sur les germes des fonctions méromorphes sur ces fibres. En montrant que ces germes de fonctions méromorphes sont algébriques, nous obtenons aussi des principes locaux-globaux sur les corps de fonctions des courbes algébriques définies sur une famille plus vaste de corps ultramétriques<br>Field patching, introduced by Harbater and Hartmann, and extended by the aforementioned authors and Krashen, has recently seen numerous applications. We present an extension of this technique to the setting of Berkovich analytic geometry and applications to the local-global principle.In particular, we show that this adaptation of patching can be applied to Berkovich analytic curves, and as a consequence obtain local-global principles over function fields of curves defined over complete ultrametric fields. Because of the connection between the points of a Berkovich analytic curve and the valuations that its function field can be endowed with, one of these local-global principles is given with respect to completions, thus evoking some similarity with more classical versions. As an application, we obtain local-global principles for quadratic forms and results on the u-invariant. These findings generalize those of Harbater, Hartmann and Krashen.As a starting point for higher-dimensional patching in the Berkovich setting, we show that this technique is applicable around certain fibers of a relative Berkovich analytic curve. As a consequence, we prove a local-global principle over the germs of meromorphic functions on said fibers. By showing that said germs of meromorphic functions are algebraic, we also obtain local-global principles over function fields of algebraic curves defined over a larger class of ultrametric fields

Abstract:
This chapter presents various results about quadratic forms over a field complete with respect to a discrete valuation. The discussion is based on the assumption that K is a field of arbitrary characteristic which is complete with respect to a discrete valuation ν‎ and uses the usual convention that ν‎(0) = infinity. The chapter starts with a notation regarding the ring of integers of K and the natural map from it to the residue field, followed by a number of propositions regarding an anisotropic quadratic space. These include an anisotropic quadratic space with residual quadratic spaces, an unramified quadratic space of finite dimension, unramified finite-dimensional anisotropic quadratic forms over K, unramified anisotropic quadratic forms and a bilinear form, and a round quadratic space over K. The chapter concludes with a theorem that there exists an anisotropic quadratic form over K, unique up to isometry, and is non-singular.

Abstract:
Chapter 10 reviews both homogeneous and inhomogeneous quantum plasma dielectric response phenomenology starting with the RPA polarizability ring diagram in terms of thermal Green’s functions, also energy eigenfunctions. The homogeneous dynamic, non-local inverse dielectric screening functions (K) are exhibited for 3D, 2D, and 1D, encompassing the non-local plasmon spectra and static shielding (e.g. Friedel oscillations and Debye-Thomas-Fermi shielding). The role of a quantizing magnetic field in K is reviewed. Analytically simpler models are described: the semiclassical and classical limits and the hydrodynamic model, including surface plasmons. Exchange and correlation energies are discussed. The van der Waals interaction of two neutral polarizable systems (e.g. physisorption) is described by their individual two-particle Green’s functions: It devolves upon the role of the dynamic, non-local plasma image potential due to screening. The inverse dielectric screening function K also plays a central role in energy loss spectroscopy. Chapter 10 introduces electromagnetic dyadic Green’s functions and the inverse dielectric tensor; also the RPA dynamic, non-local conductivity tensor with application to a planar quantum well. Kramers–Krönig relations are discussed. Determination of electromagnetic response of a compound nanostructure system having several nanostructured parts is discussed, with applications to a quantum well in bulk plasma and also to a superlattice, resulting in coupled plasmon spectra and polaritons.

Abstract:
While scholarly discussion on diplomatic law tends to focus on privileges and immunities, the VCDR has also codified provisions on duties incumbent on individual diplomats—most notably in Article 41, which includes the duty to respect local laws and obligations, the duty of non-interference, and the duty not to use mission premises ‘in any manner incompatible’ with diplomatic functions. This chapter traces the development of the scope of individual responsibility since the entry into force of the VCDR. It investigates the nature of diplomatic duties and their significance on the basis of diplomatic law, but also local law and human rights law. It also assesses options available to receiving States to hold diplomatic agents to account and to increase respect for local regulations outside the field of judicial enforcement. Examples from State practice are used to illustrate the sanctions adopted by receiving States in this context.

Abstract:
The role of military chaplains has changed over the past decade as Western militaries have deployed to highly religious environments such as East Africa, Afghanistan, and Iraq. U.S. military chaplains, who are by definition non-combatants, have been called upon by their war-fighting commanders to take on new roles beyond providing religious services to the troops. Chaplains are now also required to engage the local citizenry and provide their commanders with assessments of the religious and cultural landscape outside the base and reach out to local civilian clerics in hostile territory in pursuit of peace and understanding. In this edited volume, practitioners and scholars chronicle the changes that have happened in the field in the twenty-first century. Using concrete examples, this volume takes a critical look at the rapidly changing role of the military chaplain, and raises issues critical to U.S. foreign and national security policy and diplomacy.

Abstract:
AbstractSince plasma is high temperature and the charge particles are running with high temperature, for example, at 1 keV, about the velocity of 109 (electron) and 2 × 107 (ion) [cm/s]. Since Coulomb mean-free-path is proportional to (velocity)4, higher velocity component transfers its energy over a long distance without Coulomb collision. This is usually called as “non-local transport” and the traditional diffusion model in neutral gas cannot be applicable. In laser plasma, the locally heated electron thermal energy is transported into cold over-dense region non-locally. The best way to solve such problem is to solve Fokker-Planck equation, while it is time consuming and some theoretical models have been proposed and studied over the last four decades. The physics of such models are explained here and most recent model SNB is shown and compared to experiments. The difficulty of transport of charges particles such as electrons is how to include the effect of electrostatic field and magnetic field self-consistently.

AbstractThe effect of spatial resolution on local propagation velocity of the Turbulent/Non-Turbulent Interface (TNTI) is documented. A TNTI-local coordinate system and a Reynolds decomposition based on a TNTI-conditional averaging operation are introduced and used to assess the local velocity field and the mass and momentum balances at the TNTI layer. A clear jump of the TNTI-averaged Reynolds shear stress exists through the TNTI layer and the TNTI-averaged fluid velocity normal to the TNTI is determined by the correlation between the TNTI normal vector and the fluid velocity fluctuations around the TNTI-average fluid velocity. The TNTI-local fluid velocity field is compressive normal to the TNTI and stretching in the direction tangent to the TNTI, a structure that has important consequences.

Abstract:
AbstractDrawing on the neo-institutional notion of organizational fields, we propose the concept of the philanthropic field to conceptualize the geography of giving and the interrelations of benevolent activities across the domains of private, public, and civic sectors. Empirically, we adopt a multi-method approach, including a media analysis of reported acts of giving in the German region of Heilbronn-Franconia, a social network analysis of its regional philanthropic relations, and qualitative interviews with representatives of non-profit organizations, corporations, and public as well as private intermediaries. Based on our analysis, we conclude that the philanthropic field is constituted by diverse actors from all sectors of society who engage in specialization, division of labor, and collaboration. Moreover, practices of giving spread across geographical scales, though the majority of activity concentrates on the local and regional level. We conclude by discussing the potentials and limits of our approach as a means to gain insights into local fields of philanthropy and benevolent action across societal sectors.

Abstract:
Abstract Every organism on Earth, whether in natural or anthropogenic environments, is connected to a complex web of life, the famous 'entangled bank' coined by Darwin in 1859. Non-native species can integrate into local 'banks' by establishing novel associations with the resident species. In that context, network ecology has been an important tool to study the interactions of non-native species and the effects on recipient communities due to its ability to simultaneously investigate the assembly and disassembly of species interactions as well as their functional roles. Its visually appealing tools and relatively simple metrics gained momentum among scientists and are increasingly applied in different areas of ecology, from the more theoretical grounds to applied research on restoration and conservation. A network approach helps us to understand how plant invasions may or may not form novel species associations, how they change the structure of invaded communities, the outcomes for ecosystem functionality and, ultimately, the implications for the conservation of ecological interactions. Networks have been widely used on pollination studies, especially from temperate zones, unveiling their nested patterns and the mechanisms by which non-native plants integrate into local communities. Yet, very few papers have used network approaches to assess plant invasion effects in other systems such as plant-herbivore, plant-pathogen or seed-dispersal processes. Here we describe how joining network ecology with plant invasion biology started and how it has developed over the last few decades. We show the extent of its contribution, despite contradictory results and biases, to a better understanding of the role of non-native plant species in shaping community structure. Finally, we explore how it can be further improved to answer emerging questions.

Abstract A brief description of the process utilized in flue gas scrubbing systems is presented and the corrosion risks are analyzed in relation with the local environments wich are supposed to exist in the main parts of the installation. Then, Uniform and Localized corrosion performance of welded and non welded super-austenitic and super-duplex stainless steels are investigated and compared to nickel base alloys in laboratory conditions simulating actual flue gas desulfurization environments. The main corrosion determining parameters investigated are pH, chloride and fluoride concentration as well as temperature. Results gained from these tests were combined to field experience to design materials selection charts taking into account corrosion risks in various zones of scrubbers. Finally, field experience and references are presented.

Optimizing modeling the multilayer coextrusion flow of non-newtonian fluids through rectangular ducts: appropriate shear rate definition for a local power law formulation. Universidad de los Andes, 2024. https://doi.org/10.51573/andes.pps39.gs.ms.4.

Abstract:
The accuracy of viscosity predictions is a crucial aspect of polymer melt flow modeling and essential for the design of coextrusion die systems. In the field of non-Newtonian fluid modeling for coextrusion flows through rectangular ducts, significant progress has been made in understanding multilayer flow dynamics. Our fundamental research, employing numerical techniques such as the shooting method, finite element method, and finite difference method for flow evaluation, has established a critical base for the field. Our current research advances fluid dynamics by refining our existing numerical solver, specifically developed for multilayer coextrusion flows. We aim to enhance the solver’s performance by implementing more sophisticated calculations of shear rates that go beyond the traditional approach. The traditional approach often relies on average flow velocities and channel heights, which can underrepresent the complexity of experimentally studied polymer multilayer flows. Our study systematically compares various definitions for characteristic shear rates to describe the local shear rate dependent viscosity behavior using, for instance, a local power law model. A thorough error analysis quantifies the accuracy of each model and its predictive limitations for industrially relevant material combinations and operating conditions. This includes CFD simulations and experimental data comparisons, employing methods aligned with our fundamental research in this area. Furthermore, our work paves the way for integrating these advanced fluid dynamics models into the evolving field of process digitalization, thereby contributing to the development of more efficient, digitally integrated manufacturing processes.

Full text
Abstract:
This report describes activity conducted in several lines of research associated with field-scale water and solute processes. A major effort was put forth developing a stochastic continuum analysis for an important class of problems involving flow of reactive and non reactive chemicals under steady unsaturated flow. The field-scale velocity covariance tensor has been derived from local soil properties and their variability, producing a large-scale description of the medium that embodies all of the local variability in a statistical sense. Special cases of anisotropic medium properties not aligned along the flow direction of spatially variable solute sorption were analysed in detail, revealing a dependence of solute spreading on subtle features of the variability of the medium, such as cross-correlations between sorption and conductivity. A novel method was developed and tested for measuring hydraulic conductivity at the scale of observation through the interpretation of a solute transport outflow curve as a stochastic-convective process. This undertaking provided a host of new K(q) relationships for existing solute experiments and also laid the foundation for future work developing a self-consistent description of flow and transport under these conditions. Numerical codes were developed for calculating K(q) functions for a variety of solute pulse outflow shapes, including lognormal, Fickian, Mobile-Immobile water, and bimodal. Testing of this new approach against conventional methodology was mixed, and agreed most closely when the assumptions of the new method were met. We conclude that this procedure offers a valuable alternative to conventional methods of measuring K(q), particularly when the application of the method is at a scale (e.g. and agricultural field) that is large compared to the common scale at which conventional K(q) devices operate. The same problem was approached from a numerical perspective, by studying the feasibility of inverting a solute outflow signal to yield the hydraulic parameters of the medium that housed the experiment. We found that the inverse problem was solvable under certain conditions, depending on the amount of noise in the signal and the degree of heterogeneity in the medium. A realistic three dimensional model of transient water and solute movement in a heterogeneous medium that contains plant roots was developed and tested. The approach taken was to generate a single realization of this complex flow event, and examine the results to see whether features were present that might be overlooked in less sophisticated model efforts. One such feature revealed is transverse dispersion, which is a critically important component in the development of macrodispersion in the longitudinal direction. The lateral mixing that was observed greatly exceeded that predicted from simpler approaches, suggesting that at least part of the important physics of the mixing process is embedded in the complexity of three dimensional flow. Another important finding was the observation that variability can produce a pseudo-kinetic behavior for solute adsorption, even when the local models used are equilibrium.

Full text
Abstract:
We investigate the entry and exit of short-cycle higher education programs (SCPs), which last two or three years and can address local skill needs. Exploiting administrative data from Colombia, we study markets defined by geographic location and field of study. We find that institutions open new programs in response to local labor market demand, competition, and costs. Within markets, they often close and open programs simultaneously, possibly due to capacity constraints. SCPs are more responsive to local labor market demand than bachelor’s programs; private and non-university SCP providers are the most responsive. These findings have implications for workforce development.

Abstract:
Learning from the field is at the core of the approach that Keystone Foundation, a non-governmental organisation (NGO) based in the Nilgiri Biosphere Reserve, Western Ghats, India has been engaged in since its inception in 1993. As a group for eco-development initiatives, we engage with children and the youth from local to global, and formal and non-formal institutions. Through this report, we used the opportunity to reflect on our experiments with field learning and alternative pedagogies that are currently ongoing through the Nilgiri Field Learning Centre (a collaboration between Keystone Foundation and Cornell University) and the Climate Smart School initiative, which has been implemented in 15 schools (both private and government run). We seek to: a) explore the knowledge produced and the pedagogical approaches that have been enabled; b) examine the impact of field learning in terms of capacity; and c) reflect on our efforts at mainstreaming these pedagogies through government schools. Additionally, we collaborated with alumni from the field learning programmes to conduct a survey to assess the status of education among children belonging to indigenous communities in the Nilgiris.
