title: The political economy of taxation in Spain, 1901-1936
Creators: name: Cuenda García, Mario
Publisher: name: London School of Economics and Political Science (LSE)
Year: 2023

description: This thesis studies the political economy of taxation and its relationship with fiscal capacity in Spain between 1901 and 1936 using a provincial-level approach. The thesis constructed a completely novel dataset on twelve taxes across 48 provinces. This research shows the geographical distribution and the evolution of taxes, tax burdens and tax sacrifices between 1904 and 1934 and finds that Madrid and Barcelona were the provinces which collected the most tax revenues and had the highest tax burdens per capita, and that total real tax revenues were increasingly concentrated in the top contributing provinces. It also finds that decreases in tax burdens and tax sacrifices indicated that GDP and GDP per capita were increasing faster than tax revenues. The thesis also delves into agrarian taxation and studies creation of a land cadastre in 1906 to analyse its impact on agrarian tax pressure and discuss its implication for economic development. The findings show that the Spanish land cadastre succeeded in updating the tax bases and increased territorial contribution revenues in the provinces where it was implemented but that it did not impact agrarian tax pressure. The results suggest that the state incurred considerable opportunity cost in foregone territorial contribution revenues. The thesis studies the relationship between taxation and politics during the last two decades of the Restoration and argues that political negotiations around the Treasury were crucial in the politics of Restoration’s Spain. The thesis shows that the Spanish state did not tax efficiently across its territory and confirms that Spain had a shallow fiscal capacity in the first decades of the 20th Century.

description: The lithostratigraphy of the Triassic age strata (Dan River Group of the Newark Supergroup) in the Dan River Basin of Virginia and North Carolina is revised to consist of, in ascending order, the Pine Hall, Walnut Cove, Dry Fork, Cow Branch, and Stoneville formations. The basal Pine Hall Formation is largely fluvial and consists of red, gray, buff and relatively coarse, fluvial clastic rocks. The Walnut Cove Formation (new) consists of black and gray, largely lacustrine mudstone and minor coal. The Dry Fork Formation is comprised of gray, buff, and red lacustrine to fluvial strata. The Cow Branch Formation (restricted) is made up of mostly black and gray, predominately lacustrine mudstone and sandstone. The uppermost unit is the Stoneville Formation consisting mostly of red clastic rocks with abundant gray lacustrine, and gray and red fluvial components. All but the Pine Hall Formation show lithological cyclicity that we interpret to reflect lake level fluctuations paced by orbitally forced variations in solar insolation. Published and newly developed paleomagnetic polarity stratigraphy of the Dan River Basin provides a framework for precise temporal correlation with other Newark Supergroup basins. The extensive organic-rich, high-thermal maturity lacustrine rocks are a potential dry gas resource, given recent advances in recovery technology.

Alternating lags of QPO harmonics : A Generic model and its application to the 67 millihertz QPO of GRS 1915+105

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: A generic model for alternating lags in QPO harmonics is presented where variations in the photon spectrum are caused by oscillations in two parameters that characterize the spectrum. It is further assumed that variations in one of the parameters is linearly driven by variations in the other after a time delay $t_d$. It is shown that alternating lags will be observed for a range of $t_d$ values. A phenomenological model based on this generic one is developed which can explain the amplitude and phase lag variation with energy of the fundamental and the next three harmonics of the 67 mHz QPO observed in GRS 1915+105. The phenomenological model also predicts the variation of the Bicoherence phase with energy, which can be checked by further analysis of the observational data.

description: The soft current describes the factorization behavior of quantum chromodynamics (QCD) scattering amplitudes in the limit of vanishing energy of one of the external partons. It is process-independent and can be expanded in a perturbative series in the coupling constant. To all orders in the dimensional regularization parameter, we compute the two-loop correction to the soft current for processes involving two hard partons.

description: Once an ice sheet grows beyond a critical thickness, the basal thermal regime favors melting and development of subglacial water networks. Subglacial water is necessary for bedrock erosion, but the exact mechanisms that lead to preservation of subglacial topography are unclear. Here we resolve the freezing mechanisms that lead to long-term, high-altitude preservation across the Gamburtsev Subglacial Mountains in East Antarctica. Analyses of a comprehensive geophysical data set reveal a large-scale water network along valley floors. The ice sheet often drives subglacial water up steep topography where it freezes along high ridges beneath thinner ice. Statistical tests of hypsometry show the Gamburtsevs resemble younger midlatitude mountains, indicating exceptional preservation. We conclude that the Gamburtsevs have been shielded from erosion since the latest Eocene (∼34 Ma). These freezing mechanisms likely account for the spatial and temporal patterns of erosion and preservation seen in other glaciated mountain ranges.
Weak lensing with 21cm intensity mapping at $z \sim 2-3$

description: We study how 21 cm intensity mapping can be used to measure gravitational lensing over a wide range of redshift. This can extend weak lensing measurements to higher redshifts than are accessible with conventional galaxy surveys. We construct a convergence estimator taking into account the discreteness of galaxies and calculate the expected noise level as a function of redshift and telescope parameters. At $z \sim 2-3$ we find that a telescope array with a collecting area $\sim 0.2 \, {\rm km}^2$ spread over a region with diameter $\sim 2 \, {\rm km}$ would be sufficient to measure the convergence power spectrum to high accuracy for multipoles between 10 and 1,000. We show that these measurements can be used to constrain interacting dark energy models.

The Magellan Uniform Survey of Damped Lyman alpha Systems I: Cosmic Metallicity Evolution

description: We present the chemical abundance measurements of the first large, medium-resolution, uniformly selected damped Lyman alpha system (DLA) survey. The sample contains 99 DLAs towards 89 quasars selected from the SDSS DR5 DLA sample in a uniform way. We analyze the metallicities and kinematic diagnostics, including the velocity width of 90% of the optical depth, Δv_{90}, and the equivalent widths of the SiII 1526, CIV 1548 and MgII 2796 transitions. To avoid strong line-saturation effects on the metallicities measured in medium-resolution spectra (FWHM~71 km/s), we derived metallicities from metal transitions which absorbed at most 35% of the quasar continuum flux. We find the evolution in cosmic mean metallicity of the sample, = (-0.04 +- 0.013)z -(1.06 +- 0.36), consistent with no evolution over the redshift range z ~ [2.2, 4.4], but note that the majority of our sample falls at z ~ [2.2, 3.5]. The apparent lack of metallicity evolution with redshift is also seen in a lack of evolution in the median Δv_{90} and SiII 1526 equivalent width values. While this result may seem to conflict with other large surveys that have detected significant metallicity evolution, such as Rafelski et al. 2012 who found = (-0.22 +- 0.03)z - (0.65 +- 0.09) over z ~ [0, 5], several tests show that these surveys are not inconsistent with our new result. However, over the smaller redshift range covered by our uniformly-selected sample, the true evolution of the cosmic mean metallicity in DLAs may be somewhat flatter than the Rafelski et al. 2012 estimate.

description: Detailed $^{195}$Pt- and $^{171}$Yb nuclear magnetic resonance (NMR) studies on the heterogeneous mixed valence system YbPtGe$_2$ are reported. The temperature dependence of the $^{195}$Pt-NMR shift $^{195}K(T)$ indicates the opening of an unusual magnetic gap below 200\,K. $^{195}K(T)$ was analyzed by a thermal activation model which yields an isotropic gap $Δ/k_B \approx 200$\,K. In contrast, the spin-lattice relaxation rate $^{195}$($1/T_1$) does not provide evidence for the gap. Therefore, an intermediate-valence picture is proposed while a Kondo-insulator scenario can be excluded. Moreover, $^{195}$($1/T_1$) follows a simple metallic behavior, similar to the reference compound YPtGe$_2$. A well resolved NMR line with small shift is assigned to divalent $^{171}$Yb. This finding supports the proposed model with two sub-sets of Yb species (di- and trivalent) located on the Yb2 and Yb1 site of the YbPtGe$_2$ lattice.

Pleasure and the "bien souverain" in Gabrielle de Coignard's Oeuvres chrestiennes
Creators: name: Kenney, Susan Lord
Publisher: name: No Publisher Supplied
Year: 2020

description: The main question we set out to answer in this dissertation is: can Gabrielle de Coignard’s outlook, as perceived through her Œuvres chrestiennes, be described as hedonistic and, if so, to what extent? In Chapter I, we explore “hedonism” as a concept and philosophical tradition, as well as various conceptions of the nature and meaning of pleasure. Chapter II provides an overview of Coignard’s life as well as preliminary considerations on her ethical outlook and her sense of “calling” as a Christian poet. In Chapters III, IV, and V, a series of comparative readings assess Coignard’s conception of the sovereign good and the roles played by pleasure therein. By comparing the content and form of Coignard’s poetry – especially of Sonnet XXV, in which we find the sole occurrence of the expression “bien souverain” – with pieces written by some of her male and female contemporaries (some secular others religious), we come to appreciate specific ways in which Coignard assimilates and also rejects what her counterparts wrote on love, suffering, pleasure, and the highest good. In Chapter IV, we demonstrate how Coignard is more reticent than Anne de Marquets when making rhetorical use of the supreme “bien” and the pleasurable effects it is believed to contain. In Chapter V, a similar reticence is demonstrated with respect to Luis de Granada’s Vray chemin, from which Coignard borrows directly when writing De la gloire et felicité de la vie eternelle. Our conclusion is not only that Coignard’s implied ethical system cannot be described as hedonistic, but that she actively fights this very possibility: she explicitly names God the “seul bien souverain,” isolates the concept in its own category, makes sure to prevent any reduction of it to pleasure, and upholds this same position throughout her œuvre. She seems acutely aware that poems purporting to describe celestial bliss might both reduce it to ordinary human pleasures and make those a goal to be coveted under the guise of beatitude. That is why, when she dedicates an entire poem to the topic of “félicité,” she does not give herself full expressive license to treat this subject.

description: We study the thermal confinement/deconfinement and non-thermal quantum phase transitions or rapid cross-overs in QCD and QCD-like theories in external magnetic fields. At large magnetic fields, while the contribution of gauge fluctuations to Wilson-line potential remains unaltered at one-loop order, the contribution of fermions effectively becomes two lower dimensional and is enhanced by the density of states of the lowest Landau level (LLL). In a spatial compactification and for heavy adjoint fermions, this enhancement leads to a calculable zero temperature quantum phase transition on R^3*S^1 driven by a competition between the center-destabilizing gauge contribution and center-stabilizing LLL fermions. We also show that at a (formal) asymptotically large magnetic field, the adjoint fermions with arbitrarily large but fixed mass stabilize the center symmetry. This is an exotic case of simultaneous non-decoupling of large mass fermions (due to the enhancement by the LLL density of states) and decoupling from the low energy effective field theory. This observation has important implications for both Hosotani mechanism, for which gauge symmetry "breaking" occurs, and large-N volume independence (Eguchi-Kawai reduction), for which gauge structure is never "broken". Despite sounding almost self-contradictory, we carefully explain the physical scales entering the problem, double-meaning of unbroken center symmetry and how a clash is avoided. We also identify, for both thermal and spatial compactification, the jump in magnetic susceptibility as an order parameter for the deconfinement transition. The predictions of our analysis are testable by using current lattice techniques.

P wave analysis in cryoballoon ablation and radiofrequency ablation in paroxysmal atrial fibrillation
Creators: name: Antoun, Ibrahim
Publisher: name: University of Leicester
Year: 2023
Subjects: Uncategorized

description: Atrial fibrillation (AF) is the most prevalent sustained cardiac arrhythmia in clinical practice and can increase stroke risk five times. AF also impairs quality of life (QoL) dramatically. Pulmonary vein isolation (PVI) has recently emerged as a successful intervention to treat symptomatic paroxysmal atrial fibrillation (PAF), superior to antiarrhythmic drugs (AADs). PVI could be performed using point-bypoint radiofrequency ablation (RF) or one-shot cryoballoon ablation (cryo). This thesis included a single-centre retrospective analysis comparing clinical outcomes in RF and cryo at 12 months. Pulmonary vein (PV) reconnection patterns after failed ablation were also examined to improve both ablation techniques in particular anatomical sites. The outcome was also calculated from a patient perspective using QoL paper questionnaires. The P wave represents atrial depolarisation and alterations in its morphology could demonstrate changes in atrial electrophysiology. P wave parameters using digital 12 leads electrocardiogram (ECG) directly before and after ablation were utilised to compare differences between both ablation modalities and to predict outcomes. P wave parameters were also used to predict repeat ablation outcomes in patients who failed their first PVI. The utility of P wave mapped by body surface mapping (BSM) was explored in predicting 12 months success rates for external direct current cardioversion (DCCV) in persistent atrial fibrillation (persAF). RF and cryo demonstrated similar clinical outcomes at 12 months, similar P wave parameter changes, similar QoL improvement regardless of additional ablations, and similar PV reconnection patterns. However, there was a trend toward right lower pulmonary vein (RLPV) reconnection after failed cryo. Multiple P wave parameter changes were observed after first and second ablations. However, the change in P wave terminal force in V1 (PTFV1) after second ablation was the only potential predictor of successful outcomes at 12 months. Increased PWDc was also predictive of DCCV failure at 12 months in patients on amiodarone. This thesis provided insights into the utility of P waves in comparing ablation techniques and predicting PVI and DCCV outcomes.

The analysis is presented in the case of the Wess--Zumino model. The manifestation of the Aharonov-Anandan invariant of atoms and their superpartners, generated at non-zero temperature, could reveal the signature of SUSY violation in a recently proposed experimental setup based on an optical lattice in which SUSY is broken at non-zero temperature.

description: The properties of equilibrated tropical convection are studied using a cloud-resolving model with large-scale dynamics parameterized by the weak temperature gradient (WTG) approximation. Model integrations are performed in both 2-D and 3-D geometries. The target profile toward which horizontal mean free tropospheric temperature is relaxed is held fixed, while sea surface temperature (SST) is varied. Consistent with previous studies, large-scale ascent and precipitation increase under WTG as the SST is increased, but more rapidly in two dimensions than in three dimensions. This is related to greater extremes of near-surface buoyancy in two dimensions as well as a lower gross moist stability, and perhaps also to weaker entrainment. In both two and three dimensions, the vertical profiles of large-scale vertical velocity are top heavy and remarkably self-similar in shape as SST is increased. When all integrations are analyzed together, precipitation increases with column-integrated relative humidity once the latter reaches a threshold, as in observations and other models. However, within each integration, the two quantities are correlated negatively, albeit over a very narrow range.

description: This study investigates the October and November MJO events observed during the Cooperative Indian Ocean Experiment on Intraseasonal Variability in the Year 2011 (CINDY)/Dynamics of the MJO (DYNAMO) field campaign through cloud-permitting numerical simulations. The simulations are compared to multiple observational datasets. The control simulation at 9-km horizontal grid spacing captures the slow eastward progression of both the October and November MJO events in surface precipitation, outgoing longwave radiation, zonal wind, humidity, and large-scale vertical motion. The vertical motion shows weak ascent in the leading edge of the MJO envelope, followed by deep ascent during the peak precipitation stage and trailed by a broad second baroclinic mode structure with ascent in the upper troposphere and descent in the lower troposphere. Both the simulation and the observations also show slow northward propagation components and tropical cyclone–like vortices after the passage of the MJO active phase. Comparison with synthesized observations from the northern sounding array shows that the model simulates the passage of the two MJO events over the sounding array region well. Sensitivity experiments to SST indicate that daily SST plays an important role for the November MJO event, but much less so for the October event. Analysis of the moist static energy (MSE) budget shows that both advection and diabatic processes (i.e., surface fluxes and radiation) contribute to the development of the positive MSE anomaly in the active phase, but their contributions differ by how much they lead the precipitation peak. In comparison to the observational datasets used here, the model simulation may have a stronger surface flux feedback and a weaker radiative feedback. The normalized gross moist stability in the simulations shows an increase from near-zero values to ~0.8 during the active phase, similar to what is found in the observational datasets.

description: Using one-dimensional models, we show that a helical magnetic field with an appropriate sign of helicity can compensate the Faraday depolarization resulting from the superposition of Faraday-rotated polarization planes from a spatially extended source. For radio emission from a helical magnetic field, the polarization as a function of the square of the wavelength becomes asymmetric with respect to zero. Mathematically speaking, the resulting emission occurs then either at observable or at unobservable (imaginary) wavelengths. We demonstrate that rotation measure (RM) synthesis allows for the reconstruction of the underlying Faraday dispersion function in the former case, but not in the latter. The presence of positive magnetic helicity can thus be detected by observing positive RM in highly polarized regions in the sky and negative RM in weakly polarized regions. Conversely, negative magnetic helicity can be detected by observing negative RM in highly polarized regions and positive RM in weakly polarized regions. The simultaneous presence of two magnetic constituents with opposite signs of helicity is shown to possess signatures that can be quantified through polarization peaks at specific wavelengths and the gradient of the phase of the Faraday dispersion function. Similar polarization peaks can tentatively also be identified for the bi-helical magnetic fields that are generated self-consistently by a dynamo from helically forced turbulence, even though the magnetic energy spectrum is then continuous. Finally, we discuss the possibility of detecting magnetic fields with helical and non-helical properties in external galaxies using the Square Kilometre Array.

Summertime post-cold-frontal marine stratocumulus transition processes over the eastern North Atlantic
Creators: name: Kazemi Rad, Melissa
Publisher: name: No Publisher Supplied
Year: 2020

description: The Marine stratocumulus cloud system is a major component of the Earth’s energy budget. Mid-latitude stratocumulus are known to transition from a single, continuous cloud layer to a hybrid configuration that includes both stratocumulus and cumulus, and eventually to trade cumulus toward the tropics. Stratocumulus transitions are often observed in the wake of cold air outbreaks in the mid-latitude summertime marine boundary layer (MBL). Cloud morphology associated with two summertime cold fronts over the Eastern North Atlantic (ENA) is investigated using high resolution simulations from the Weather Research and Forecasting (WRF) model and observations from the Atmospheric Radiation Measurement (ARM) ENA Climate Research Facility. Lagrangian trajectories are used to study the evolution of post-cold-frontal MBL clouds from solid stratocumulus to broken cumulus. Clouds within specified domains in the vicinity of transitions are classified according to their degree of decoupling, and cloud-base and cloud-top breakup processes are evaluated. The Lagrangian derivative of the surface latent heat flux is found to be strongly correlated with that of the cloud fraction at cloud base in the simulations. Cloud-top entrainment instability (CTEI) is shown to operate only in the decoupled MBL. A new indicator of inversion strength at cloud top that employs the vertical gradients of equivalent potential temperature and saturation equivalent potential temperature, which can be computed directly from soundings, is proposed as alternative to CTEI. Overall results suggest that the deepening-warming hypothesis suggested by Bretherton and Wyant explains many of the characteristics of the summertime post-frontal MBL evolution of cloud structure over the ENA, thereby widening the phase space over which the hypothesis may be applied. A subset of the deepening-warming hypothesis involving warming initially dominating over moistening is proposed. It is postulated that changes in climate-change induced modifications in cold frontal structure over the ENA may be accompanied by coincident changes in the location and timing of MBL cloud transitions in the post-cold-frontal environment.

description: Variations in deep convective activity during the 4 month Tropical Ocean Global Atmosphere-Coupled Ocean Atmosphere Response Experiment (TOGA-COARE) field campaign are simulated using a cloud-resolving model (CRM). Convection in the model is coupled to large-scale vertical velocities that are parameterized using one of two different methods: the damped gravity wave (Damped-wave) method and the weak temperature gradient (WTG) method. The reference temperature profiles against which temperature anomalies are computed are taken either from observations or from a model integration with no large-scale vertical motion (but other forcings taken from observations); the parameterized large-scale vertical velocities are coupled to those temperature (or virtual temperature) anomalies. Sea surface temperature, radiative fluxes, and relaxation of the horizontal mean horizontal wind field are also imposed. Simulations with large-scale vertical velocity imposed from the observations are performed for reference. The primary finding is that the CRM with parameterized large-scale vertical motion can capture the intraseasonal variations in rainfall to some degree. Experiments in which one of several observation-derived forcings is set to its time-mean value suggest that those which influence direct forcings on the moist static energy budget—surface wind speed and sea surface temperature (which together influence surface evaporation) and radiative cooling—play the most important roles in controlling convection, particularly when the Damped-wave method is used. The parameterized large-scale vertical velocity has a vertical profile that is too bottom-heavy compared to observations when the Damped-wave method is used with vertically uniform Rayleigh damping on horizontal wind, but is too top-heavy when the WTG method is used.

description: Results for the leading two-loop corrections of $\mathcal{O}{\left(α_t^2\right)}$ from the Yukawa sector to the Higgs-boson masses of the MSSM with complex parameters are presented. The corresponding self-energies and their renormalization have been obtained in a Feynman-diagrammatic approach. A numerical analysis of the new contributions is performed for the mass of the lightest Higgs boson, supplemented by the full one-loop result and the $\mathcal{O}{\left(α_t α_s\right)}$ terms including complex phases. In the limit of the real MSSM a previous result is confirmed.

description: The problem of providing meaningful routing directions over road networks is of great importance. In many real-life cases, the fastest route may not be the ideal choice for providing directions in written, spoken text, or for an unfamiliar neighborhood, or in cases of emergency. Rather, it is often more preferable to offer "simple" directions that are easy to memorize, explain, understand or follow. However, there exist cases where the simplest route is considerably longer than the fastest. This paper tries to address this issue, by finding near-simplest routes which are as short as possible and near-fastest routes which are as simple as possible. Particularly, we focus on efficiency, and propose novel algorithms, which are theoretically and experimentally shown to be significantly faster than existing approaches.

description: We study effects of AGN feedback outflows on multi-phase inter stellar medium (ISM) of the host galaxy. We argue that SMBH growth is dominated by accretion of dense cold clumps and filaments. AGN feedback outflows overtake the cold medium, compress it, and trigger a powerful starburst -- a positive AGN feedback. This predicts a statistical correlation between AGN luminosity and star formation rate at high luminosities. Most of the outflow's kinetic energy escapes from the bulge via low density voids. The cold phase is pushed outward only by the ram pressure (momentum) of the outflow. The combination of the negative and positive forms of AGN feedback leads to an $M-σ$ relation similar to the result of King (2003). Due to porosity of cold ISM in the bulge, SMBH influence on the low density medium of the host galaxy is significant even for SMBH well below the $M-σ$ mass. The role of SMBH feedback in our model evolves in space and time with the ISM structure. In the early gas rich phase, SMBH accelerates star formation in the bulge. During later gas poor (red-and-dead) phases, SMBH feedback is mostly negative everywhere due to scarcity of the cold ISM.
