Abstract:
Stretched hydrogels make uniformly anisotropic environments for quadrupolar nuclei such as 2H, 23Na, and 133Cs. Such surroundings cause the partial alignment of nuclear spin bearing ions and molecules that is sufficiently pronounced to alter the nuclear magnetic resonance spectra of the guest species. In most cases, resonance splittings are directly related to the spin quantum number I. The relative intensities of the components of the resonance multiplets can be inferred from basic quantum mechanics.

Abstract:
The accurate calculation of the isotropic (Jiso) and anisotropic (ΔJ) parts of indirect nuclear spin–spin coupling tensors is a stringent test for quantum chemistry, particularly for couplings involving heavy isotopes where relativistic effects and relativity – electron correlation cross terms are expected to play an important role. Experimental measurements on diatomic molecules in the gas phase offer ideal data for testing the success of computational approaches, since the data are essentially free from intermolecular effects, and precise coupling anisotropies may be reliably extracted in favourable cases. On the basis of available experimental molecular-beam coupling-tensor parameters for diatomic alkali metal halides, we tabulate known values of Jiso and, taking rotational–vibrational corrections to the direct dipolar coupling constant into account, precise values of ΔJ are determined for the ground rovibrational state. First-principles calculations of the coupling tensors were performed using a recently developed program based on hybrid density functional theory using the two-component relativistic zeroth-order regular approximation (ZORA). Experimental trends in Jiso and ΔJ are reproduced with correlation coefficients of 0.993 and 0.977, respectively. Periodic trends in the coupling constants and their dependence on the product of the atomic numbers of the coupled nuclei are discussed. Finally, the hybrid functional method is also successfully tested against experimental data for a series of polyatomic xenon fluorides and group-17 fluorides.

AbstractMost of what we know about active galactic nuclei (AGNs) has been driven, or at least strongly shaped, by our methods for finding them, and multiwavelength AGN surveys have achieved remarkable successes in recent decades. I will present a broad, and thus necessarily shallow, review of such multiwavelength AGN surveys. I will first present some brief introductory points on, e.g., general survey approaches, AGN luminosities, host galaxies, and anisotropic emission/obscuration. I will then review many of the key current surveys and their results, separating these into ground-based and space-based surveys. Finally, I will discuss some future prospects including essential remaining questions and “discovery space” considerations.

Abstract:
Context. Breathtaking imagery recorded during the European Space Agency Rosetta mission confirmed the bilobate nature of the nucleus of comet 67P/Churyumov-Gerasimenko. The peculiar appearance of the nucleus is not unique among comets. The majority of cometary cores imaged at high resolution exhibit a similar build. Various theories have been brought forward as to how cometary nuclei attain such peculiar shapes. Aims. We illustrate that anisotropic mass loss and local collapse of subsurface structures caused by non-uniform exposure of the nucleus to solar irradiation can transform initially spherical comet cores into bilobed cores. Methods. We derived a mathematical framework to describe the changes in morphology resulting from non-uniform insolation during the spin-orbit evolution of a nucleus. We solved the resulting partial differential equations that govern the change in the shape of a nucleus subject to mass loss and consequent collapse of depleted subsurface structures analytically for simple insolation configurations and numerically for more realistic scenarios. Results. The proposed mechanism is capable of explaining why a large percentage of periodic comets appear to have peanut-shaped cores and why light-curve amplitudes of comet nuclei are on average larger than those of typical main belt asteroids of the same size.

Abstract:
Using the quantum molecular dynamics model, we study the nuclear dynamics at the balance energy of mass asymmetric colliding nuclei by keeping the total mass of the system fixed and by varying the mass asymmetry (η = (AT-AP)/(AT+AP), where AT and AP are the masses of the target and projectile, resp.) of the reaction. In particular, we study the various quantities like average and maximum density and temperature, collision rate, participant-spectator matter, anisotropic ratio, relative momentum, and their mass asymmetry and mass dependence. Our results indicate sizeable effect of mass asymmetry on these quantities.

Abstract:
Heteronuclear spin interactions in solids and anisotropic liquids can be removed by phase modulated decoupling sequences with frequency sweep, such as SWf-TPPM and its variants. The performance of these sequences in isotropic spin systems with regard to the experimental parameters, phase angle, and decoupler offset is presented here. A comparison is made with other commonly used heteronuclear decoupling schemes in liquids, namely, WALTZ-16, GARP, and MLEV. Also, the trajectories of nuclear magnetization vector of abundant nuclei in a simple spin system during TPPM and SWf-TPPM decoupling sequences are traced out using computer simulations.

Abstract:
Lo scopo della presente tesi è quello di discutere i risultati ottenuti durante i miei studi di dottorato, principalmente rivolti a problemi non locali. Per prima cosa ci occupiamo di principi di continuazione unica forte ed espansioni asintotiche locali in determinati punti del bordo per soluzioni di due diverse classi di equazioni ellittiche. In particolare, partiamo con lo studio di una classe di equazioni ellittiche frazionarie in un dominio limitato sotto una condizione al contorno di Dirichlet omogenea esterna. Per fare ciò, sfruttiamo la procedura di estensione di Caffarelli-Silvestre, grazie alla quale il problema non locale può essere riformulato in modo equivalente come problema locale in una dimensione in più, generando un problema con condizioni miste. Dopodichè, utilizziamo un'idea classica di Garofalo e Lin per ottenere una condizione di raddoppio tramite una formula di monotonia per la funzione di Almgren. Per superare le difficoltà legate alla perdita di regolarità in corrispondenza della transizione tra le regioni di Dirichlet e di Neumann, introduciamo una nuova tecnica basata su un argomento di approssimazione, che ci permette di derivare una cosiddetta identità di tipo Pohozaev necessaria per stimare la derivata della funzione di Almgren . Otteniamo così un risultato di continuazione unica forte nel contesto locale, che viene a sua volta combinato con l’analisi di blow-up per dedurre espansioni asintotiche locali e, di conseguenza, una continuazione unica forte anche nel contesto non locale. Inoltre forniamo anche un risultato di continuazione unica forte dal bordo di una fessura per le soluzioni di una classe specifica di equazioni ellittiche del secondo ordine in un dominio limitato aperto con una frattura, su cui è assegnata una condizione al contorno di Dirichlet omogenea. Questo problema locale è correlato a un caso particolare dello studio descritto sopra, in virtù di una forte connessione tra questo tipo di problemi e i problemi al contorno con condizioni miste. Nella presente dissertazione, trattiamo anche una teoria della capillarità non locale. In particolare, consideriamo nuclei di interazione più generali che sono possibilmente anisotropici e non necessariamente invarianti rispetto allo stesso riscalamento. In particolare, la perdita di invarianza è modellata utilizzando due diversi esponenti frazionari per tenere conto della possibilità che il contenitore e l'ambiente presentino caratteristiche diverse rispetto alle interazioni delle particelle. Determiniamo inoltre una legge di Young non locale per l'angolo di contatto tra la gocciolina e la superficie del contenitore e discutiamo la solvibilità e l’unicità della soluzione dell'equazione corrispondente in termini di nuclei di interazione e del relativo coefficiente di adesione.
The aim of the present thesis is to discuss the results obtained during my PhD studies, mainly devoted to nonlocal issues. We first deal with strong unique continuation principles and local asymptotic expansions at certain boundary points for solutions of two different classes of elliptic equations. We start the investigation by a class of fractional elliptic equations in a bounded domain under some outer homogeneous Dirichlet boundary condition. To do this, we exploit the Caffarelli-Silvestre extension procedure, which allows us to get an equivalent formulation of the nonlocal problem as a local problem in one dimension more, consisting in a mixed Dirichlet-Neumann boundary value problem. Then, we use a classical idea by Garofalo and Lin to obtain a doubling-type condition via a monotonicity formula for a suitable Almgren-type frequency function. To overcome the difficulties related to the lack of regularity at the Dirichlet-Neumann junction, we introduce a new technique based on an approximation argument, which leads us to derive a so-called Pohozaev-type identity needed to estimate the derivative of the Almgren function. Thus we gain a strong unique continuation result in the local context, which is in turn combined with blow-up arguments to deduce local asymptotics and, consequently, a strong unique continuation result in the nonlocal setting as well. We also provide a strong unique continuation result from the edge of a crack for the solutions to a specific class of second order elliptic equations in an open bounded domain with a fracture, on which a homogeneous Dirichlet boundary condition is prescribed, in the presence of potentials satisfying either a negligibility condition with respect to the inverse-square weight or some suitable integrability properties. This local problem is related to a particular case of the setting described above, by virtue of a strong connection between this type of problems and the mixed Dirichlet-Neumann boundary value problems. We also treat a capillarity theory of nonlocal type. In our setting, we consider more general interaction kernels that are possibly anisotropic and not necessarily invariant under scaling. In particular, the lack of scale invariance is modeled via two different fractional exponents in order to take into account the possibility that the container and the environment present different features with respect to particle interactions. We determine a nonlocal Young's law for the contact angle between the droplet and the surface of the container and discuss the unique solvability of the corresponding equation in terms of the interaction kernels and of the relative adhesion coefficient.

Abstract:
Physical forces in the cellular microenvironment play an important role in governing cell function. Forces transmitted through the cell cause distinct deformation of the nucleus, and possibly play a role in force-mediated gene expression. The work presented in this thesis drew upon innovative strategies employing simultaneous atomic force and laser-scanning confocal microscopy, as well as parallel optical stretching experiments, to gain unique insights into the response of eukaryotic cell nuclei to external force. Non-destructive approaches confirmed the existence of a clear anisotropy in nuclear mechanical properties, and showed that the nucleus' mechanical response to extracellular forces is differentially governed by both nuclear and cytoskeletal prestress: nuclear prestress regulates shape and anisotropic deformation, whereas cytoskeletal prestress modulates the magnitude and degree of deformation. Importantly, the anisotropic mechanical response was conserved among diverse differentiated cell types from multiple species, suggesting that nuclear mechanical anisotropy plays an important role in cell function.

Full text
Abstract:
The angular dependence of the differential scattering cross section is typically represented as a truncated Legendre series expansion. If the scattering cross section is highly anisotropic, these expansions may result in negative regions in the -1 ≤ μ0 ≤ +1 interval, thus representing the cross section by negative values. These negative regions may cause negative components in the discrete ordinates scattering source, which are non-physical and which may adversely affect the iterative convergence of the exponential discontinuous spatial discretization scheme. Two methods are presented which produce a positive representation of the scattering cross section, and are designed to calculate a strictly positive scattering source. The first method constructs a scattering matrix from the exponential representation of the cross section derived from maximum entropy. Accuracy of these matrices is further improved by the application of SMART scattering theory. The second method adjusts the Legendre cross section moments with a constrained least squares algorithm. The adjustment is subject to constraints that the zeroth and first moment remain unchanged and that the resulting expansion is positive on all scattering angle cosines derived from a standard S N quadrature set. Extra moments from the maximum entropy representation of the cross section are also used to decrease the relative error of the modified moments. Numerical transport calculations using these two methods demonstrate consistent results with those using the standard truncated Legendre expansion of the cross section. The exponential discontinuous spatial scheme is shown to iteratively converged when these two methods are used. A comparison of these methods with results from multigroup and continuous energy Monte Carlo calculations are also shown to be consistent.

Full text
Abstract:
The linear Boltzmann equation for the transport of neutral particles is investigated with the objective of generating benchmark-quality calculations for homogeneous infinite media. In all cases, the problems are stationary, of one energy group, and the scattering is both isotropic and anisotropic. In the transport problems considered, the Green's function is generally the quantity of interest. The solution is obtained through the use of the Fourier transform method. The numerical inversions use standard numerical techniques, such as Gauss-Legendre quadrature, summation of infinite series, and Euler-Knopp acceleration. The most basic source of neutral particles is the point-beam source, or Green's function source. The Green's function in an infinite medium with isotropic scattering is treated as explained in chapter two. The Green's function in an infinite medium with anisotropic scattering is treated using two different mathematical methods as explained in chapters three and four. The results for both cases is shown in chapter 5.

Abstract:
This chapter is devoted to one of key phenomena in the field of spin physics, namely, resonant absorption of electromagnetic waves under conditions where the Zeeman splitting of spin levels in magnetic field is equal to photon energy. This method is particularly important for identification of nuclear spin effects, because resonance spectra provide fingerprints of different involved spin species and make it possible to distinguish different nuclear isotopes. As discussed in this chapter the nuclear magnetic resonance provides also an access to local magnetic fields acting on nuclear spins. These fields are caused by the magnetic interactions between the nuclei and by the quadrupole splittings of nuclear spin states in anisotropic crystalline environment. Manifestations of spin resonance in optical responses of semiconductors–that is, optically detected magnetic resonance–are discussed.

Abstract:
The neutronics characterization of The University of Utah TRIGA reactor core focused at evaluating the effects of anisotropic neutron scattering is based on 3D AGENT methodology. The AGENT methodology is based on method of characteristics with exact modeling of geometry and material distribution in the reactor cores. This feature is unique to deterministic codes worldwide and is based on the originally developed R-function solid modeler. The anisotropic correction to neutron transport in 3D hexagonal and square reactors as implemented in AGENT, provides highly accurate solution with no limitations to core configuration or the degree of anisotropic scattering terms. In testing this new methodology on TRIGA type reactors, we conclude that the AGENT deterministic solution with P2 anisotropic scattering approximation provides fully comparable solution to the MCNP5 but with 93% CPU-time reduction.

An improved anisotropic eddy viscosity model has been developed for accurate predictions of the thermal hydraulic performances of nuclear reactor fuel assemblies. The proposed model adopts a non-linear formulation of the stress-strain relationship in order to include the reproduction of the anisotropic phenomena, and in combination with an optimized low-Reynolds-number formulation based on Direct Numerical Simulation (DNS) to produce correct damping of the turbulent viscosity in the near wall region. This work underlines the importance of accurate anisotropic modeling to faithfully reproduce the scale of the turbulence driven secondary flows inside the bundle subchannels, by comparison with various isothermal and heated experimental cases. The very low scale secondary motion is responsible for the increased turbulence transport which produces a noticeable homogenization of the velocity distribution and consequently of the circumferential cladding temperature distribution, which is of main interest in bundle design. Various fully developed bare bundles test cases are shown for different geometrical and flow conditions, where the proposed model shows clearly improved predictions, in close agreement with experimental findings, for regular as well as distorted geometries. Finally the applicability of the model for practical bundle calculations is evaluated through its application in the high-Reynolds form on coarse grids, with excellent results.
