description: Folded carbonates are host to a significant portion of the world’s hydrocarbon reservoirs. To date, analog data to aid prediction of the style, intensity, and distribution of critical strain elements such as opening-mode fractures is limited. Prediction of strain distribution and connectivity of fracture systems is especially problematic within interstratified carbonate and siliciclastic/argillaceous lithologies that create strong mechanical anisotropies. Documentation of the structural processes and stratigraphic architecture on a full spectrum of scales and across a well-constrained structure was conducted to provide a better understanding of deformation styles. The geometry and structural mechanisms associated with the growth of the Gobbler Anticline, a north-trending, doubly plunging, fault-propagation fold above a blind, basement rooted reverse fault with en echelon tear faults was constrained via a balanced cross-section, virtual outcrop models, and orthomosaic photographs. The Gobbler Anticline consists of tightly folded and faulted mixed lithofacies; specifically, thick-bedded (1.0-10.0 m) limestones intercalated with thin-bedded (laminated - 1.0 m) clay-rich intervals, characteristic of the Bug Scuffle Member of the Gobbler Formation. Measured sections (totaling 470 m) assess the distribution of facies while mechanical rock property analyses document the unconfined compressive strength of the rocks. Thin sections and X-Ray fluorescence provide improved understandings of lithological controls on deformational mechanisms. Pre-Permian unconformities and thinning of the overlying mid-upper Pennsylvanian strata indicate shallow overburden (< 500 m) at the time of initial fold deformation (Missourian, ~307 Ma). We find that argillaceous wackestones are disproportionately weakened when involved in folding soon after deposition and mechanical layering is the dominant control on fracture development in more deformed areas. This study illustrates the value of a tightly constrained mechanical stratigraphic model for the prediction of fracture distribution and fold geometry

description: We have constructed a modified BFT method that preserves the chain structure of constraints. This method has two advantages: first, it leads to less number of primary constraints such that the remaining constraints emerge automatically; and second, it gives less number of independent gauge parameters. We have applied the method for bosonized chiral Schwiger model. We have constructed a gauge invariant embedded Lagrangian for this model.

description: Iterative subdomain methods for the Stokes--Darcy problem that use Robin boundary conditions on the interface are reviewed. Their common underlying structure and their main differences are identified. In particular, it is clarified that there are different updating strategies for the interface conditions. For small values of fluid viscosity and hydraulic permeability, which are relevant in applications from geosciences, it is shown in numerical studies that only one of these updating strategies leads to an efficient numerical method, if this strategy is used in combination with appropriate parameters in the Robin boundary conditions. In particular, it is observed that the values of appropriate parameters are larger than those proposed so far. Not only the size but also the ratio of appropriate Robin parameters depends on the coefficients of the problem.

description: We study the evolution of ionization fronts around the first proto-galaxies by using high resolution numerical cosmological (Lambda+CDM model) simulations and Monte Carlo radiative transfer methods. We present the numerical scheme in detail and show the results of test runs from which we conclude that the scheme is both fast and accurate. As an example of interesting cosmological application, we study the reionization produced by a stellar source of total mass M=2 10^8 M_\odot turning on at z=12, located at a node of the cosmic web. The study includes a Spectral Energy Distribution of a zero-metallicity stellar population, and two Initial Mass Functions (Salpeter/Larson). The expansion of the I-front is followed as it breaks out from the galaxy and it is channeled by the filaments into the voids, assuming, in a 2D representation, a characteristic butterfly shape. The ionization evolution is very well tracked by our scheme, as realized by the correct treatment of the channeling and shadowing effects due to overdensities. We confirm previous claims that both the shape of the IMF and the ionizing power metallicity dependence are important to correctly determine the reionization of the universe.

description: We show how magnetic observations of the Sun can be used in conjunction with an axisymmetric flux-transport solar dynamo model in order to estimate the large-scale meridional circulation throughout the convection zone. Our innovative approach rests on variational data assimilation, whereby the distance between predictions and observations (measured by an objective function) is iteratively minimized by means of an optimization algorithm seeking the meridional flow which best accounts for the data. The minimization is performed using a quasi-Newton technique, which requires the knowledge of the sensitivity of the objective function to the meridional flow. That sensitivity is efficiently computed via the integration of the adjoint flux-transport dynamo model. Closed-loop (also known as twin) experiments using synthetic data demonstrate the validity and accuracy of this technique, for a variety of meridional flow configurations, ranging from unicellular and equatorially symmetric to multicellular and equatorially asymmetric. In this well-controlled synthetic context, we perform a systematic study of the behavior of our variational approach under different observational configurations, by varying their spatial density, temporal density, noise level, as well as the width of the assimilation window. We find that the method is remarkably robust, leading in most cases to a recovery of the true meridional flow to within better than 1%. These encouraging results are a first step towards using this technique to i) better constrain the physical processes occurring inside the Sun and ii) better predict solar activity on decadal time scales.

description: Defining the role of Ancestral Rocky Mountain (ARM) tectonics on basin evolution and infill is critical for hydrocarbon exploration and development in the Permian and Orogrande basins, yet the timing and controls of late Paleozoic ARM deformation remain poorly constrained. We document these relationships in the Pennsylvanian–Permian Bursum Formation., which preserves a continuous record of deposition synchronous with uplift of the adjacent Pedernal fold-thrust belt. Sedimentation took place between two end-member depositional systems: 1) a shallowly dipping, carbonate ramp, and 2) an alluvial fan-deltaic siliciclastic system. The newly developed high-resolution stratigraphic framework from nine measured sections averaging 94 m in thickness shows that the Bursum Formation transitions from open-marine ammonite-bearing shales at the base to nonmarine conglomerates at the top. Provenance analyses indicate that alluvial fans were localized along active faults and clasts were sourced from uplifted upper Paleozoic strata and Pedernal metamorphic basement. Paleocurrent data reveal key paleotopographic features that influenced facies distributions, with a shift to multimodal patterns identified in offshore littoral sand bodies. Growth strata, soft-sediment deformation, fault-slip analysis, and unconformable contact relationships with the underlying Pennsylvanian Holder Formation and overlying Permian Abo Formation. show that deposition occurred contemporaneously with compressional and right-lateral oblique slip along the Pedernal uplift. These results and cross section restoration show that the Fresnal Fault and La Luz Anticline experienced a resurgent phase of ARM tectonism that peaked in the latest Virgilian (~301 Ma) and rapidly waned into the earliest Wolfcampian (~296 Ma). These findings constrain the poorly understood timing of the end of ARM deformation and provide insight into a key gap in the stratigraphic record of southern New Mexico and west Texas

description: For many applications, we are unable to take full advantage of the potential massive parallelisation offered by supercomputers or cloud computing because it is too hard to work out how to divide up the computation task between processors in such a way to minimise the need for communication. However, a recently developed branch-independent tableaux for the common LTL temporal logic should intuitively be easy to parallelise as each branch can be developed independently. Here we describe a simple technique for partitioning such a tableau such that each partition can be processed independently without need for interprocess communication. We investigate the extent to which this technique improves the performance of the LTL tableau on standard benchmarks and random formulas.

description: I develop a three-step framework to model the anisotropic elastic properties of a mechanically compacted mudrock based on the full strain tensor. I model the microstructure as an effective medium representative of locally aligned domains of clay grains and fluid filled porosity with isolated quartz. Then I predict the orientation of these building blocks due to the application of any strain field. Finally, the previous two steps are combined to determine an effective medium model for the entire mudrock that predicts the elastic stiffness matrix. I focus on the relationship of deformation to porosity reduction and grain alignment in mudrocks. My results show that the application of axial loading leads to the development of elastic anisotropy with stiffnesses increasing more rapidly in the direction perpendicular to loading. These stiffness predictions closely match experimental data on a mudrock specimen from Eugene Island – Gulf of Mexico. I further apply my three-step framework to predict elastic stiffnesses in a synthetic salt basin based on the full strain tensor predicted by an evolutionary poromechanical model. This coupling allows us to predict elastic stiffnesses and anisotropy due to sediment deposition and non-uniaxial salt loading. Accurate estimation of elastic stiffnesses for mudrocks based on the full strain tensor holds immense potential to improve pressure prediction, seismic imaging in complex geologic environments, and prospect evaluation

Systematic comparison of different machine learning based earthquake detection methods

description: A major goal of installing seismic arrays is to detect and locate earthquakes. Earthquake detection and location are fundamental problems in seismology, are the foundation for techniques such as tomography, and are crucial for better understanding the physics of earthquakes and earthquake hazard. However, there are many challenges in detecting earthquakes, including noise in seismic data or overlapping waves from different phases or events. Recent developments in earthquake detection methods include state-of-art approaches using machine learning, such as PhaseNet and EQtranformer. These methods are trained on large volumes of quality-controlled, labelled seismic data and have demonstrated promising results. The inputs for such methods are three-component seismic waveforms without waveform pre-processing, and the output is the probability of P or S wave arrivals at each time point in the seismic traces. These methods can greatly improve temporal accuracy in the detection problem and also reduce the human labor to pre-process data and set thresholds for different windows of a seismic record. We test these two methods using a new data set called the Unconstrained Utah Event Bulletin (UUEB), where local and regional earthquake arrivals in Utah have been closely identified by human analysts, providing a means of ground-truthing the machine learning detection algorithms. This data set includes continuous seismic waveforms recorded on broadband and short-period seismometers. Crucially, these datasets were not used in training of the machine learning methods, allowing for a true out-of-sample test. Our results with the UUEB dataset show that PhaseNet is good at picking P waves but not S waves and is prone to false detections. EQtransformer has nearly equal detection results both for P and S phases but much fewer detection results overall compared with PhaseNet. Overall, our results suggest that the successful application of machine learning based earthquake detection algorithms may require retraining using a given data set as opposed to a simple application of a code trained on a different data set. However, our results also highlight limitations in “ground truth”, human-analyzed detections, demonstrating that neither traditional nor state-of-the-art techniques can accomplish the earthquake detection task error-free

description: Modular Graph Functions (MGFs) are SL(2,$\mathbb{Z}$)-invariant functions that emerge in the study of the low-energy expansion of the one-loop closed string amplitude. To find the string scattering amplitude, we must integrate MGFs over the moduli space of the torus. In this paper, we use the iterated integral representation of MGFs to establish a depth-dependent basis for them, where "depth" refers to the number of iterations in the integral. This basis has a suitable Laplace equation. We integrate this basis from depth zero to depth three over the fundamental domain of SL(2,$\mathbb{Z}$) with a cut-off.

description: Geophysical surveys are the most effective way to model the surface and subsurface. Recorded signals can only be converted to properties of interest, such as rock type or saturating fluid, if we understand the relationship between rocks and their physical properties. Digital rock physics (DRP) consists of creating digital models of rocks in order to numerically model their properties. Computed Tomography (CT) scans are a common starting place for DRP models. Each model consists of voxels (3D pixels), with values in units of CT number, which are an approximation of X-ray attenuation in that location. The conventional method of converting CT-numbers into rock properties is known as segmentation. Users assign physical properties to each voxel based off the visually identified material that the voxel represents. Segmentation introduces arbitrariness causing certain rock properties to be drastically incorrect. Measuring some sample properties in the laboratory for calibration is a common mitigation. Here, we introduce a new segmentation-less DRP method and present case studies suggesting that we can considerably improve the prediction of rock physical properties and match physical laboratory results. Chapter one demonstrates that by scanning objects of known density alongside the rock sample, we can calibrate the rock model. We refer to the method as “predictive”, as sample laboratory measurements are not required. We explain the steps to create density, porosity, and wave velocity models, and derive a method to estimate uncertainty. In chapter two, we acquired CT scans with varying conditions to test the sensitivity of the method. We provide advice and reasoning on how to set up an effective scan. In chapter three, we estimate rock properties from millimetric sized sandstone fragments too small to test with conventional equipment. We also estimate properties for meteorite samples too rare to invasively test. This shows the method is more than academic, and can meaningfully contribute to scientific debate and industry decisions. We have shown that CT, a relatively new technology not widely adopted for this purpose, can be used to accurately solve rock physics problems when we combine knowledge from material science. This more accurate methodology could make this powerful technology more mainstream for rock physicists

description: We formulate quasistatic nonlinear finite-strain viscoelasticity of rate-type as a gradient system. Our focus is on nonlinear dissipation functionals and distances that are related to metrics on weak diffeomorphisms and that ensure time-dependent frame-indifference of the viscoelastic stress. In the multidimensional case we discuss which dissipation distances allow for the solution of the time-incremental problem. Because of the missing compactness the limit of vanishing timesteps can only be obtained by proving some kind of strong convergence. We show that this is possible in the one-dimensional case by using a suitably generalized convexity in the sense of geodesic convexity of gradient flows. For a general class of distances we derive discrete evolutionary variational inequalities and are able to pass to the time-continuous in some case in a specific case.

description: We consider ten-dimensional supersymmetric Yang-Mills theory (10D SUSY YM theory) and its dimensional reductions, in particular, BFSS and IKKT models. We formulate these theories using algebraic techniques based on application of differential graded Lie algebras and associative algebras as well as of more general objects, L_{\infty}- and A_{\infty}- algebras. We show that using pure spinor formulation of 10D SUSY YM theory equations of motion and isotwistor formalism one can interpret these equations as Maurer-Cartan equations for some differential Lie algebra. This statement can be used to write BV action functional of 10D SUSY YM theory in Chern-Simons form. The differential Lie algebra we constructed is closely related to differential associative algebra Omega of (0, k)-forms on some supermanifold; the Lie algebra is tensor product of Omega and matrix algebra . We construct several other algebras that are quasiisomorphic to Omega and, therefore, also can be used to give BV formulation of 10D SUSY YM theory and its reductions. In particular, Omega is quasiisomorphic to the algebra B constructed by Berkovits. The algebras Omega_0 and B_0 obtained from Omega and B by means of reduction to a point can be used to give a BV-formulation of IKKT model. We introduce associative algebra SYM as algebra where relations are defined as equations of motion of IKKT model and show that Koszul dual to the algebra B_0 is quasiisomorphic to SYM.

description: The pressures of giant HII regions in 6 dwarf Irregular galaxies are a factor of ~10 larger than the average pressures of the corresponding galaxy disks, obtained from the stellar and gaseous column densities. Either the visible HII regions in these dwarfs are all so young that they are still expanding, or there is an unexpected source of disk self-gravity that increases the background pressure. We consider the possibility that the additional self-gravity comes from disk dark matter, but suggest this is unlikely because the vertical scale heights inferred for Irregular galaxies are consistent with the luminous matter alone. Some of the HII region overpressure is probably the result of local peaks in the gravitational field that come from large gas concentrations, many of which are observed directly. These peaks also explain the anomalously low average column density thresholds for star formation that were found earlier for Irregular galaxies, and they permit the existence of a cool HI phase as the first step toward dense molecular cores. Many of the HII regions could also be so strongly over-pressured that they will expand for a long time. In this case, the observed population would be only 7% of the total, and the aging HII regions, now too faint to see, should occupy nearly the entire dwarf galaxy volume. Such prolonged HII region expansion would explain the origin of the giant HI shells that are seen in these galaxies, and account for the lack of bright central clusters inside these shells.

description: Abstract: "The oscillatory properties of a weak convergent sequence of gradients may be decoupled from its deformation properties, a localization property easily shown. Of greater interest is that oscillations may be coupled to a sequence and limit deformation assuming only a kinematic condition and technical condition. This suggests the question of what measures, that is to say, ordinary measures not parametrized measures, may occur as limits of sequences of gradients. We show that they may be characterized by a form of Jensen's inequality for a special class of quasiconvex functions. The consequences of this disparity are of some interest in understanding the sort of approximations, or processes, which lead to complicated microstructures and are relevant to the nature of approximation by Lipshitz functions in general."

description: Recently, Matsukawa et al. have discovered a new superconductor Pr_2Ba_4Cu_7O_15-delta in which metallic CuO double chains are responsible for the superconductivity. To investigate the superconductivity, we employ the d-p double chain model where the tight-binding parameters are determined so as to fit the LDA band structure. On the basis of the Tomonaga-Luttinger liquid theory, we obtain the phase diagram including the superconducting phase in the weak coupling limit. We also calculate the Luttinger liquid parameter K_rho as a function of the electron density $n$ by using the Hartree-Fock approximation. With increasing $n$ from quarter filling, K_rho increases, and then exceeds 1/2 when the superconducting correlation becomes most dominant. K_rho has a maximum at an optimal density between quarter- and half-filling. These results are consistent with the experimental observation.

description: A relativistic $π$-nucleon potential is extended to $m^* \neq m$ to investigate the possibility of generating s-wave $π$-nucleus repulsion. We find that relativity does indeed generate significant repulsion, the exact amount depending on the details of the calculation. In contradistinction the $tρ$ approximation gives very little repulsion.

description: The weather extremes associated with mesoscale convective systems (MCSs) over the Great Plains have substantial socio-economic impacts on the regions’ diverse and growing society. It remains unclear how anthropogenic warming will affect the climate of this region in the future due to large uncertainties in simulated precipitation changes by climate models and a lack of knowledge about the long-term variability of these storms. This dissertation seeks to improve our understanding of the climate dynamics of the Great Plains, focusing on using past changes in MCS activity and hydroclimate to understand their responses to external forcings. To do so, I generate a 20,000-year record of MCS activity and hydroclimate in central Texas using the D/H ratios of sedimentary leaf waxes coupled with trace element analysis and carbon isotope composition of bulk organic matter. To improve our confidence in the interpretation of hydrogen isotope data, I first investigate the meteorological controls on the isotopic composition of precipitation in the Great Plains, which suggests that the isotopic ratios of rainwater mainly reflect the magnitude of the dominating MCS storms over this region, with larger and stronger MCSs producing more negative isotopic values and vice versa. Based on our improved understanding of the regional isotope systematics, our multi-proxy record shows pronounced responses of MCS to external forcings (i.e., retreating ice sheets, solar insolation) on orbital to centennial timescales. Results from transient climate model simulations indicate that variations in the intensity of the Great Plains Low-Level Jet in response to springtime land surface warming can account for these changes in MCS activity. Differential springtime warming over the continent and the North Atlantic drives steeper zonal temperature and pressure gradients over the Great Plains, intensifying the Great Plains Low-Level Jet which consequently enhances the magnitude of Great Plains MCSs via increased moisture availability. These results provide important implications for the potential responses of Great Plains MCS activity to anthropogenic warming, where more pronounced land surface warming relative to the ocean may dynamically intensify future storms with increased risks for extreme weather in the Great Plains
Lagrange method in shape optimization for non-linear partial differential equations: A material derivative free approach

description: This paper studies the relationship between the material derivative method, the shape derivative method, the min-max formulation of Correa and Seeger, and the Lagrange method introduced by Céa. A theorem is formulated which allows a rigorous proof of the shape differentiability without the usage of material derivative; the domain expression is automatically obtained and the boundary expression is easy to derive. Furthermore, the theorem is applied to a cost function which depends on a quasi-linear transmission problem. Using a Gagliardo penalization the existence of optimal shapes is established.

description: We analyze the radiative forces between two dielectric nanospheres mediated via the quantum and thermal fluctuations of the electromagnetic field in the presence of an external drive. We generalize the scattering theory description of fluctuation forces to include external quantum fields, allowing them to be in an arbitrary quantum state. The known trapping and optical binding potentials are recovered for an external coherent state. We demonstrate that an external squeezed vacuum state creates similar potentials to a laser, despite its zero average intensity. Moreover, Schrödinger cat states of the field can enhance or suppress the optical potential depending on whether they are odd or even. Considering the nanospheres trapped by optical tweezers, we examine the total interparticle potential as a function of various experimentally relevant parameters, such as the field intensity, polarization, and phase of the trapping lasers. We demonstrate that an appropriate set of parameters could produce mutual bound states of the two nanospheres with potential depth as large as $\sim200$ K. Our results are pertinent to ongoing experiments with trapped nanospheres in the macroscopic quantum regime, paving the way for engineering interactions among macroscopic quantum systems.

description: Ionic layer epitaxy (ILE) has recently been developed as an effective strategy to synthesize nanometer-thick 2D materials with a non-layered crystal structure, such as ZnO. The packing density of the amphiphilic monolayer is believed to be a key parameter that controls the nanosheet nucleation and growth. In this work, we systematically investigated the growth behavior of single-crystalline ZnO nanosheets templated at the water-air interface by an anionic oleylsulfate monolayer with different packing densities. The thicknesses of ZnO nanosheets were tuned from one unit cell to four unit cells, and exhibited good correlation with the width of Zn2+ ion concentration zone (the Stern layer) underneath the ionized surfactant monolayer. Further analysis of the nanosheet sizes and density revealed that the nanosheet growth was dominated by the steric hindrance from the surfactant monolayer at lower surface pressure; while the nucleation density became the dominating factor at higher surface pressure. The ZnO nanosheets exhibited a decreasing work function as the thickness reduced to a few unit cells. This research validated a critical hypothesis that the nanosheet growth is self-limited by the formation of a double layer of ionic precursors. This work will open up a new way towards controlled synthesis of novel 2D nanosheets from non-layered materials with a thickness down to one unit cell.

description: We construct a replica field theory for a random matrix model with logarithmic confinement [K.A.Muttalib et.al., Phys. Rev. Lett. 71, 471 (1993)]. The corresponding replica partition function is calculated exactly for any size of matrix $N$. We make a color-flavor transformation of the original model and find corresponding Toda lattice equations for the replica partition function in both formulations. The replica partition function in the flavor space is defined by generalized Itzikson-Zuber (IZ) integral over homogeneous factor space of pseudo-unitary supergroups $SU(n\mid M,M)/SU(n\mid M-N,M)$ (Stiefel manifold) with $M\to\infty$, which is evaluated and represented in a compact form.

description: Marine ecosystems are undergoing increasing environmental pressure from climate change and industry developments. These environmental pressures are particularly impacting in the Arctic. Increased monitoring of Arctic marine ecosystems with active acoustic surveys could improve our understanding of the ecological impacts from climate change stressors. However, traditional research vessel-based surveys are very expensive, have limited availability and measure a disrupted pelagic environment by introducing light and noise. We propose that broadband echosounders mounted on uncrewed vehicles, moorings or lowered probes would provide complementary measurements to address these shortcomings. In the case of uncrewed vehicles, they could complement traditional vessel-based surveys by extending the temporal and spatial extent. Because broadband echosounders are relatively new technologies, methods and standard processing procedures need to be modified and tested. The present thesis studies three methods for broadband echosounders to increase the independence of acoustic data from research vessels for monitoring marine ecosystems, with the Arctic as a case study. The three methods are the inverse method, model-informed classification and mesocosm-informed classification. These methods aim to increase the information retrieved from acoustic data by maximizing the use of the broadband target spectra measurements. The methods are applied to sound scattering layers of zooplankton aggregations, individual zooplankton, shrimp, and fish to advance methods for analyzing broadband acoustic data from uncrewed vehicles or moorings where few or no direct sampling data are available. However, new challenges intrinsic to broadband echosounders and their signal processing arise, such as understanding the sensitivity of broadband measurements of targets as individuals and as aggregations. To conclude, I discuss the applicability of these methods for ecosystem-based fisheries management and commercial fishing. I conclude on the progress towards fulfilling the promise of broadband acoustics for species identification.
