Refined topological amplitudes in N=1 flux compactification

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

description: We study the implication of refined topological string amplitudes in the supersymmetric N=1 flux compactification. They generate higher derivative couplings among the vector multiplets and graviphoton with generically non-holomorphic moduli dependence. For a particular term, we can compute them by assuming the geometric engineering. We claim that the Dijkgraaf-Vafa large N matrix model with the beta-ensemble measure directly computes the higher derivative corrections to the supersymmetric effective action of the supersymmetric N=1$ gauge theory.

Down to Earth: Knowledge Based Approaches for Heterogeneous Geospatial Data Management
Creators: name: Booma Sowkarthiga Balasubramani
Publisher: name: University of Illinois at Chicago
Year: 2020
Subjects: Uncategorized

description: Geospatial data integration involves combining two or more geospatial datasets to facilitate analysis, reasoning, querying, and data visualization. The availability of data in itself is not sufficient to bring the concept of data integration to its full potential. Primary reasons are that data come from disparate sources and are fundamentally heterogeneous. Some prominent challenges in integrating geospatial data includes differences in format, representation, context, structure, events, data models, spatio-temporal resolution, data collection and storage techniques, and the relationship between various system properties in a given region. Also, as with any real-world data, geospatial data are dirty. That is, they are most often erroneous, incomplete, and inconsistent, leading to uncertainty. All these factors affect a data integration system, resulting in imprecise results when the data are analyzed. Therefore, in the process of designing a reliable data integration system, one has to address the problems of dealing with dirty data, as well as the heterogeneity and uncertainty that comes with the data. This dissertation aims at developing geospatial data integration techniques that address several types of heterogeneities in data. First, we introduce a context-aware pre-processing technique that incorporates domain knowledge to resolve any errors and inconsistencies in geospatial data, prior to data integration. Second, we describe Semantic Web-based techniques that use ontologies to handle the integration of geospatial datasets that: (i) exhibit different forms of heterogeneity; (ii) are of different data formats and/or of different categories; and (iii) have different spatio-temporal resolutions. In addition, we also present a tree-based spatial data structure to represent and index heterogeneous geospatial data, along with an algorithm for efficient processing of spatial queries, allowing for some (bounded) uncertainty in the query results. This dissertation describes the background, challenges and approaches in integrating the geospatial data in a seamless manner, and highlight the results of the experiments focusing on a wide range of real-world scenarios.
Clustering-Initialized Adaptive Histograms and Probabilistic Cost Estimation for Query Optimization
Creators: name: Khachatryan, Andranik
Publisher: name: Karlsruhe
Year: 2012

description: An assumption with self-tuning histograms has been that they can "learn" the dataset if given enough training queries. We show that this is not the case with the current approaches. The quality of the histogram depends on the initial configuration. Starting with few good buckets can improve the efficiency of learning. Without this, the histogram is likely to stagnate, i.e. converge to a bad configuration and stop learning. We also present a probabilistic cost estimation model.

description: This is the first study who presents an approach to predict secondary metabolites content in tomatoes using multivariate time series classification of greenhouse sensor data, which includes climatic conditions as well as photosynthesis and transpiration rates. The aim was to find the necessary conditions in a greenhouse to determine the maximum content of secondary metabolites, as higher levels in fruits can promote human health. For this, we defined multiple classification tasks and derived suitable classification function. Cross-validated high accuracy results demonstrate the effectiveness of the approach. Considering a period of three weeks, we found that PPFD levels between 396.0 μmol/m2s and 511.2 μmol/m2s as well as transpiration rates ranging from 4.4 mg H2O/m2s to 7.47 mg H2O/m2s were observed as optimal for the contents of beta carotene, lutein, and lycopene. Optimal contents for naringenin and phloretin diglucoside can be achieved at lower PPFD ranges from 229.4 μmol/m2s to 431.2 μmol/m2s and from 35.76 μmol/m2s to 262.28 μmol/m2s and at lower transpiration rates from 4.71 to 6.47 mg H2O/m2s and from 3.04 to 4.26 mg H2O/m2s, respectively. It was discovered for the first time that, photosynthesis rates also play a significant role in the accumulation of secondary metabolites. Photosynthesis rates between 0.39 μmol CO2/m2s and 1.21 μmol CO2/m2s over three weeks were crucial for the optimal accumulation of phenolic acids such as caffeic acid derivates, coumaric acid hexoside, ferulic acid hexoside and coumaroylquinic acids as well as for quercetin and flavonoid. An optimal temperature range between 20.94 and 21.53°C and a PPFD from 250.0 to 375.2 μmol/m2s was classified as beneficial to synthesize these compounds. Optimal light intensity for the total phenolic acids (129.35 - 274.34 μmol/m2s) and for the total flavonoids (31.24 - 249.31 μmol/m2s), the optimum relative humidity levels are between 83.45 - 91.29% and 87.13 - 91.29%, respectively. Based on these results, this study provides the first evidence that the impact of a single climate factor on secondary metabolites in tomato fruits should not be considered in isolation, but rather, all climatic factors during a growth period must be taken into account to predict the optimal accumulation of individual phenolic compounds and carotenoids in tomatoes. Our results have laid the headstone to help growers target their climate controls to maximize the health-promoting phytochemicals in tomatoes.
See-saw neutrino masses and large mixing angles in the vortex background on a sphere

description: In the vortex background on a sphere, a single 6-dimensional fermion family gives rise to 3 zero-modes in the 4-dimensional point of view, which may explain the replication of families in the Standard Model. Previously, it had been shown that realistic hierarchical mass and mixing patterns can be reproduced for the quarks and the charged leptons. Here, we show that the addition of a single heavy 6-dimensional field that is gauge singlet, unbound to the vortex, and embedded with a bulk Majorana mass enables to generate 4D Majorana masses for the light neutrinos through the see-saw mechanism. The scheme is very predictive. The hierarchical structure of the fermion zero-modes leads automatically to an inverted pseudo-Dirac mass pattern, and always predicts one maximal angle in the neutrino see-saw matrix. It is possible to obtain a second large mixing angle from either the charged lepton or the neutrino sector, and we demonstrate that this model can fit all observed data in neutrino oscillations experiments. Also, U_{e3} is found to be of the order ~0.1.

description: This thesis discusses deflectometry as a reconstruction method for highlyreflecting surfaces. It explains the measurement process and principle and provides a crash course into an efficient mathematical representation of the principles involved.

Viscoelastic Focusing and Sorting of Particles and Asymmetric Cells in Straight Microfluidic Channels
Creators: name: Barilla, Ludovica
Publisher: name: University of Illinois at Chicago
Year: 2020
Subjects: Uncategorized

description: Worldwide, infertility affects more than 70 million couple1–3 and it has been reported that 50% of these cases4 can be accounted for male patients; among these men, 10 to 15% suffer from azoospermia4, which is defined as the lack of sperm in the ejaculate sample5. Patients suffering from nonobstructive azoospermia (NOA) can still have children thanks to procedures such as testicular sperm extraction (TESE) from a testicular biopsy sample6,7 but the presence of an abundance of red blood cells (RBCs) remain the main impediment in this technique8. Indeed, the isolation of the few spermatozoa from the sample has to be performed manually as filtration methods are inefficient and also time consuming6. Currently, there is no device that is able to perform erythrocytes-sperm separation in an efficient, cost-effective, and clinically feasible way. Here, we demonstrate a simple microfluidic straight channel with a rectangular cross-section, which is able to separate sperm cells from erythrocytes by exploiting the viscoelastic effect of the medium. Our device was made in polydimethylsiloxane with the classic soft-lithography procedures, making it simple and low cost. We extensively investigated multiple channels with different geometrical characteristics (100 μm x 50 μm, 50 μm x 25 μm, 25 μm x 50 μm, 75 μm x 25 μm) using spherical polystyrene particles of different sizes (15, 10, 7, 4, 2 μm diameter) as cell surrogates. This was done to find the optimal geometrical and flow conditions in which the asymmetric cell separation could be possible. During our investigation, we optimized the concentration of the viscoelastic fluid needed for the focusing, the channel length at which both particles and cells showed stable equilibrium positions, and the flow conditions for the optimum performance. We also investigated the 3D behavior of particles inside 50 μm x 25 μm channel and we were able to test RBCs and sperm cells together in a 75 μm x 25 μm channel, demonstrating a high efficiency of separation (> 86% for RBCs and > 59% for spermatozoa). Finally, in the open outlets design channel, we demonstrated the perfect (~ 100%) purity and efficiency of sorting with 4 and 7 μm particles at flow rates lower than 5 μL/min. Ultimately, our study demonstrates high purity separation and collection of spermatozoa is possible, making our device suitable for the clinical application of in vitro fertilization procedures.

description: We study experimentally and theoretically, the reorganization of superconducting vortices driven by oscillatory forces near the plastic depinning transition. We show that the system can be taken to configurations that are tagged by the shaking parameters but keep no trace of the initial conditions. In experiments performed in $NbSe_2$ crystals, the periodic drive is induced by ac magnetic shaking fields and the overall order of the resulting configuration is determined by non invasive ac susceptibility measurements. With a model of interacting particles driven over random landscapes, we perform molecular dynamics simulations that reveal the nature of the shaking dynamics as fluctuating states similar to those predicted for other interacting particle systems.

Cosmic ray electrons and positrons from discrete stochastic sources

description: The distances that galactic cosmic ray electrons and positrons can travel are severely limited by energy losses to at most a few kiloparsec, thereby rendering the local spectrum very sensitive to the exact distribution of sources in our galactic neighbourhood. However, due to our ignorance of the exact source distribution, we can only predict the spectrum stochastically. We argue that even in the case of a large number of sources the central limit theorem is not applicable, but that the standard deviation for the flux from a random source is divergent due to a long power law tail of the probability density. Instead, we compute the expectation value and characterise the scatter around it by quantiles of the probability density using a generalised central limit theorem in a fully analytical way. The uncertainty band is asymmetric about the expectation value and can become quite large for TeV energies. In particular, the predicted local spectrum is marginally consistent with the measurements by Fermi-LAT and HESS even without imposing spectral breaks or cut-offs at source. We conclude that this uncertainty has to be properly accounted for when predicting electron fluxes above a few hundred GeV from astrophysical sources.

Deterministic Control Strategy for a Hybrid Hydraulic System with Intermediate Pressure Line
Creators: name: Dengler, Peter
name: Geimer, Marcus
name: Dombrowski, René Von
Publisher: name: Karlsruhe
Year: 2012

description: The paper introduces a new hydraulic system for mobile machines based on a constant pressure system with the aim to increase the efficiency of actuation of hydraulic cylinders. Using a third pressure level located between high pressure and tank pressure called intermediate pressure the system enables additional pressure potentials from high pressure to intermediate pressure and from intermediate pressure to tank pressure. This reduces throttle losses at hydraulic cylinders when driven at low or medium loads. An accumulator connected to the intermediate pressure line is being charged or discharged in function of which pressure potential is currently used. 

Due to the discrete pressure potentials of the system a control strategy is required which reduces throttle losses at the proportional valves and allows maximum recuperation of potential energy. Best results can be obtained if the future loads on the cylinders are predictable. For this reason a Model Predictive Control (MPC) was developed for a wheel loader which was used as a reference system. By using its specific geometric properties the MPC allows a precise load prediction as a function of the piston’s position. Using the criteria of Bellman, an analytic online calculation of the optimum sequence of pressure potentials and their durations for one complete cylinder stroke can be effectuated using Dynamic Programming. This leads to a deterministic algorithm which is easy to handle and which can be implemented into an online control loop of the wheel loader. The paper furthermore shows how an optimal switching sequence and the optimal accumulator parameters can be found offline using multi objective optimization and closes with simulation results showing an increase of efficiency of 13% compared to a LS system at the example of a typical duty cycle of a wheel loader.

description: In the context of a strongly coupled Electroweak Symmetry Breaking, composite triplet of heavy vectors degenerate in mass belonging to the $SU(2)_{L+R}$ adjoint representation may arise from a new strong interaction invariant under the global $SU(2)_L\times SU(2)_R$ symmetry, which is spontaneously broken down to $SU(2)_{L+R}$. Assuming that the interactions among these heavy vector states and with the Standard Model gauge bosons are described by a $SU(2)_L\times SU(2)_R/SU(2)_{L+R}$ Effective Chiral Lagrangian, the heavy vector pair production at the LHC by Vector Boson Fusion and Drell-Yan annihilation is studied in this framework. The expected rates of same sign di-lepton and tri-lepton events from the decay of the composite vectors into Standard Model gauge bosons are computed.

Sex differences in the integrated response to high respiratory muscle work during exercise
Creators: name: Dominelli, Paolo Biagio
Publisher: name: University of British Columbia
Year: 2017

description: Purpose. The purpose of this thesis was to investigate sex differences in the integrated response to high respiratory muscle work during exercise. To accomplish this, I developed two novel methodologies (Chapters 2 & 4) in order to answer two subsequent research questions (Chapters 3 & 5). Methods. Chapter 2: Using computer software coupled with physiological measurements, I measured the oxygen cost of exercise hyperpnea in healthy subjects. Chapter 3: Healthy men and women performed voluntary hyperpnea while the oxygen cost of breathing was determined. The absolute and relative oxygen cost of breathing was compared between the sexes at different absolute and relative ventilation. Chapter 4: Using readily available components, I developed a proportional assist ventilator that could operate during all exercise intensities. Chapter 5: Healthy men and women completed three time-to-exhaustion (TTE) tests and quadriceps muscle fatigue was measured after each. The first TTE served as a control and during the 2nd and 3rd either a hyperoxic mixture was inspired or the work of breathing was lowered. Conclusion The oxygen cost of breathing can be consistently and reproducibly measured in healthy women when the work of breathing during exercise is precisely matched (Chapter 2). At ventilations above ~55 l min-¹, women have a greater oxygen cost of exercise hyperpnea. During intense exercise, the oxygen uptake of the respiratory muscles in women represents a greater fraction of total oxygen uptake (Chapter 3). A proportional assist ventilator can reduce the work of breathing to <70% of control values while maintaining spontaneous breathing patterns. The degree of unloading can be altered, but not in a precise manner (Chapter 4). Hypoxemia equally influences the development of quadriceps fatigue in both sexes. Conversely, due to their higher oxygen cost of breathing, manipulating the work of breathing has a greater influence on quadriceps fatigue in women. The collection of these studies indicates that the normally occurring work of breathing during exercise influences the integrated response to exercise to a greater degree in healthy women.

description: Recently Kaloper, Kleban and Martin reexamined the McVittie solution and argued, contrary to a very widely held belief, that the solution contains a black hole in an expanding universe. Here we corroborate their main conclusion but go on to examine, in some detail, a specific solution that asymptotes to the $Λ$CDM cosmology. We show that part of the boundary of the solution contains the inner bifurcation two - sphere of the Schwarzschild - de Sitter spacetime and so both the black and white hole horizons together form a partial boundary of this McVittie solution. We go on to show that the null and weak energy conditions are satisfied and that the dominant energy condition is satisfied almost everywhere in the solution. The solution is understood here by way of a systematic construction of a conformal diagram based on detailed numerical integrations of the null geodesic equations. We find that the McVittie solution admits a degenerate limit in which the bifurcation two - sphere disappears. For solutions with zero cosmological constant, we find no evidence for the development of a weak null singularity. Rather, we find that in this case there is either a black hole to the future of an initial singularity or a white hole to its past.

description: We analyze multi-wavelength data of a M7.9/1N class solar flare which occurred on 27 April, 2006 from AR NOAA 10875. GOES soft X-ray images provide the most likely signature of two interacting loops and their reconnection, which triggers the solar flare. TRACE 195 A images also reveal the loop-loop interaction and the formation of `X' points with converging motion (~30 km/s) at the reconnection site in-between this interacting loop system. This provides the evidence of progressive reconnection and flare maximization at the interaction site in the active region. The absence of type III radio burst during this time period indicates no opening of magnetic field lines during the flare energy release, which implies only the change of field lines connectivity/orientation during the loop-loop interaction and reconnection process. The Ondrejov dynamic radio spectrum shows an intense decimetric (DCIM) radio burst (2.5--4.5 GHz, duration ~3 min) during flare initiation, which reveals the signature of particle acceleration from the reconnection site during loop-loop interaction. The double peak structures at 4.9 and 8.8 GHz provide the most likely confirmatory signature of the loop-loop interaction at the flare site in the active region. RHESSI hard X-ray images also show the loop-top and footpoint sources of the corresponding two loop system and their coalescence during the flare maximum, which act like the current carrying flux-tubes with resultant opposite magnetic fields and the net force of attraction. We also suggest that the shear motion/rotation of the footpoint of the smaller loop, which is anchored in the opposite polarity spot, may be responsible for the flare energy buildup and then its release due to the loop-loop interaction.

Thereby, cost cap components fix an upper cost ceiling, after which consumption is exempt from further costs. The thesis demonstrates the use of different methodologies in order to study the effects of these pricing schemes. Implications for consumers and providers caused by the extension of tariffs by a cost cap component are discussed in detail.

description: Salinity does not only stress plants but also the biologists who sincerely try to discriminate its tangled elements. Adaptation to salinity is not provided by one single 'master-switch', but must have evolved from tuning the cross-talk of different regulatory circuits. A model for salt adaptation is developed, where efficient quenching of JA-signaling determines whether grapevine cells recognise the early stress signals as salinity related or defense-related.

description: This study followed the responses of actin filaments and microtubules to flg22 and HrpZ in vivo by spinning-disc confocal microscopy in Green fluorescent protein (GFP)-tagged marker lines of tobacco BY-2. Cytoskeletal disruption is proposed as an early event that discriminates HrpZ-triggered ETI-like defence from flg22-triggered PTI. We have generated a transgenic grapevine plant line of Vitis vinifera 'Chardonnay' expressing a fusion protein between GFP and the second actin-binding domain of Arabidopsis (Arabidopsis thaliana) fimbrin, AtFIM1 (pK7WGF2-FABD2), and a suspension cell line of the American Rock Grape Vitis rupestris expressing Arabidopsis beta-Tubulin-6 N-terminally fused to GFP (pCambia1300(CAA)n 2XT-gfp-Tub6). Our work succeeded to integrate life-cell imaging of the cytoskeleton into the model plant grapevine and thus to investigate the function of actin filaments and microtubules in context that is highly relevant for application in agriculture.

Probing Biological Performance Diversity and the Discovery of Autophagy-Specific Inhibitors

description: The current generation of high-throughput screening (HTS) involves the parallel processing of hundreds of thousands of molecules. Despite such large-scale efforts, low hit rates for challenging targets slow the overall rate of novel therapeutic discovery. The success of future screening campaigns for unmet needs can be supported by advances in the quantification of the biological performance diversity and the prediction of chemical features that enhance this diversity. Compound libraries that are biologically performance-diverse contain molecules that have broad, nonredundant coverage of a large set of biological targets. These libraries would accelerate drug discovery by increasing hit rates while reducing the overall footprint of HTS. In this work we present the profiling of two flavonoid-based libraries using the Cell Painting assay to establish which types of chemical and physical features are most relevant for the composition of biologically performance-diverse libraries. We conclude that the impact of varying features is highly dependent on the scaffold around which a library is based further emphasizing the need to screen libraries as they are synthesized to inform synthetic efforts. Autophagy is a catabolic process implicated in a variety of human diseases due to its role in the maintenance of cellular homeostasis. During autophagy, cellular cargo is sequestered within double-membrane autophagosomes which traffic these contents to the lysosome for recycling. Many autophagy modulators exist, but these modulators lack overall specificity, either impacting autophagy at several points within the pathway or affecting other pathways within the cell. To better understand the role of autophagy in various diseases, we need to develop autophagy-specific probes that can be used to evaluate the underlying biology and serve as the starting points for the creation of effective therapies. We approached this problem by targeting two protein-protein interactions (PPIs) found within the autophagy pathway, the ATG14L-Beclin 1 PPI and the ATG5-ATG16L1 PPI. To target these interfaces, we developed two HTS-compatible assays utilizing NanoBRET and fluorescence polarization, respectively. We successfully implemented the NanoBRET HTS to discover a novel molecule that inhibits the formation of VPS34 Complex I and disrupts autophagy more selectively than known autophagy inhibitors that target the VPS34 kinase directly.
Dislocations Jam At Any Density

description: Crystalline materials deform in an intermittent way via dislocation-slip avalanches. Below a critical stress, the dislocations are jammed within their glide plane due to long-range elastic interactions and the material exhibits plastic response, while above this critical stress the dislocations are mobile (the unjammed phase) and the material fails. We use dislocation dynamics and scaling arguments in two dimensions to show that the critical stress grows with the square root of the dislocation density. Consequently, dislocations jam at any density, in contrast to granular materials, which only jam below a critical density.

description: We charge an individual donor with electrons stored in a quantum dot in its proximity. A Silicon quantum device containing a single Arsenic donor and an electrostatic quantum dot in parallel is realized in a nanometric field effect transistor. The different coupling capacitances of the donor and the quantum dot with the control and the back gates are exploited to generate a relative rigid shift of their energy spectrum as a function of the back gate voltage, causing the crossing of the energy levels. We observe the sequential tunneling through the $D^{2-}$ and the $D^{3-}$ energy levels of the donor hybridized at the oxide interface at 4.2 K. Their respective states form an honeycomb pattern with the quantum dot states. It is therefore possible to control the exchange coupling of an electron of the quantum dot with the electrons bound to the donor, thus realizing a physical qubit for quantum information processing applications.

Schimmelreitergeschichte : companion species and cultural techniques in Jahrhundertwende novellas by Hofmannsthal and Storm
Creators: name: Kage, Melanie
Publisher: name: University of British Columbia
Year: 2017

description: The thesis at hand investigates horse-riding in two novellas of the German Jahrhundertwende era: Hugo von Hofmannsthal’s Reitergeschichte (1899) and Theodor Storm’s Der Schimmelreiter (1888). Cultural and Literary Animals Studies (CLAS), a newly evolving, interdisciplinary area of research, constitutes the framework for the analysis which focuses on equitation as a human-animal relationship with cultural and literary entanglements. Two theories from the larger context of posthumanism and concerned with humanimal practices are used to untangle the multitude of agents involved in riding: the Companion Species (CS) approach as introduced by Donna Haraway and the Cultural Techniques (CT) approach as introduced by German Media Studies scholars. The CS concepts allow an analysis of the human-equine figures and contact zones in the texts, while the CT notions enable an examination of the recursive chains of operations in horse-riding as a body technique. I have combined the approaches to engage with the material and semiotic complexities of equitation. Entangling them generates new methodological tools: world-making, emerging thirds, natureculturalization and earthiness. The literary texts are accompanied by research in Equitation Science and horsemanship manuals to enable even deeper practical insights. The interpretations of Reitergeschichte and Der Schimmelreiter untangle the concatenated links, loops, and liminal zones between the rhythmic movements of rider, horse and earthy ground. Therefore, the earthiness of riding stands out and in a larger conceptual and cultural context, it indicates the seismic shifts of the Jahrhundertwende’s trembling transitions in art, science and society, and humanity’s grounding troubles. The thesis thereby expands the CLAS framework into the fields of Ecocriticism and Environmental Humanities.
