description: La Integridad Académica es un concepto multidimensional que puede ser entendido como un compromiso con los seis valores fundamentales de honestidad, confianza, equidad, respeto, responsabilidad y coraje, como también puede ser entendido como la integridad de las instituciones en todos los procesos que se desarrollan dentro del espacio educativo. Esta presentación se concentra en la segunda noción, a partir de la exploración de la literatura con un foco en cómo las instituciones de educación superior, a nivel internacional, han tomado acciones concretas de liderazgo para hacer frente a nuevas amenazas como el fraude de contrato y el uso no ético de la inteligencia artificial. Dentro de lo anterior, las políticas constituyen uno de los elementos más críticos, por lo que la presentación también presenta una síntesis de la situación actual de las políticas de integridad académica a nivel chileno. De forma complementaria, se abordan algunas recomendaciones generales dirigidas a académicos que faciliten la promoción de la integridad académica a nivel de aulas universitarias.

description: The cosmic string is a useful probe of the early Universe and may give us a clue to physics at high energy scales where any artificial particle accelerators cannot reach. Although one of the most promising tools is the cosmic microwave background, the constraint from gravitational waves is becoming so stringent that one may not hope to detect its signatures in the cosmic microwave background. In this paper, we construct a scenario that contains cosmic strings observable in the cosmic microwave background while evading the constraint imposed by the recent pulsar timing data. We argue that cosmic strings with relatively large tension are allowed by delaying the onset of the scaling regime. We also show that this scenario is naturally realized in the context of chaotic inflation in supergravity, where the phase transition is governed by the Hubble induced mass.

Quenches in a quasi-disordered integrable lattice system: Dynamics and statistical description of observables after relaxation

description: We study the dynamics and the resulting state after relaxation in a quasi-disordered integrable lattice system after a sudden quench. Specifically, we consider hard-core bosons in an isolated one-dimensional geometry in the presence of a quasi-periodic potential whose strength is abruptly changed to take the system out of equilibrium. In the delocalized regime, we find that the relaxation dynamics of one-body observables, such as the density, the momentum distribution function, and the occupation of the natural orbitals, follow, to a good approximation, power laws. In that regime, we also show that the observables after relaxation can be described by the generalized Gibbs ensemble, while such a description fails for the momentum distribution and the natural orbital occupations in the presence of localization. At the critical point, the relaxation dynamics is found to be slower than in the delocalized phase.

description: This thesis provides contributions to improving the efficiency of solving norm equations over global function fields F and providing theoretical and empirical evidence of the improvement. We present two new algorithms for solving norm equations over F; one is an exhaustive search algorithm inspired by the sole existing method in [21], and the other is an algorithm using principal ideal testing via index calculus. We employed compact representations in both of the novel algorithms to represent solutions in less space and also to improve their efficiency. In order to compare the asymptotic and practical efficiency of the novel algorithms to the existing one, we performed rigorous complexity analyses and empirical analyses of the algorithms. We provided the asymptotic complexities of the algorithm as the number of bit operations required. We also analyzed for the first time the complexity of the algorithm for computing compact representations in [15] as a part of the complexity analyses of the novel algorithms. The asymptotic complexities of both of our novel algorithms were reduced by double exponential factors in the size of F, when compared to the existing algorithm in [21]. The new algorithm with principal ideal testing requires even fewer bit operations than the new exhaustive search algorithm in terms of the size of F. Empirical testing results demonstrate our novel algorithms are significantly faster than the existing one in practice as expected from the complexity analyses.

description: We describe a method for determination of physical conditions in the broad line regions of a significant subsample of Seyfert-1 nuclei and quasars. Several diagnostic ratios based on intermediate (AlIII 1860, SiIII 1892) and high (CIV 1549, SiIV 1397) ionization lines in the UV spectra of quasars are used to constrain density, ionization and metallicity of the emitting gas. We apply the method to two extreme Population A quasars - the prototypical NLSy1 I Zw 1 and a high-z\ NLSy1-like object, SDSS J120144.36+011611.6. We find well-defined physical conditions: low ionization (ionization parameter $< 10^{-2}$), high density (10$^{12} - 10^{13}$ cm^{-3}) and significant metal enrichment. Ionization parameter and density can be derived independently for each source with an uncertainty that is always less than $\pm 0.3$ in logarithm. We use the product density times ionization parameter to estimate the broad line region radius and the virial black hole mass. Estimates of black hole masses based on the "photoionization" analysis described in this paper are probably more accurate than those derived from the radius - luminosity correlation.

The Socratic analysis of nobility and beauty : politics, wisdom, and the divine in Plato's Greater Hippias
Creators: name: O'Toole, Daniel Frederick
Publisher: name: The University of Texas at Austin
Year: 2022
Subjects: Plato

description: This dissertation provides a comprehensive interpretation of the Greater Hippias, Plato’s dialogue on nobility and beauty. It helps shed light on a crucial dimension of Plato’s political philosophy, for according to him, nobility and beauty are among the most important yet contentious aspects of moral, political, and religious life. In the course of interpreting the Greater Hippias, the dissertation seeks to clarify how Plato understands the nature and character of nobility and beauty and the various ways in which they hold meaning and relevance for our individual and political lives. This requires tracing his analysis of what all is implied in the conventional conception of nobility and beauty and the natural basis of our attachment to it. The dissertation concludes, first of all, that the Greater Hippias shows that the kind of nobility that seems most impressive to us serves the common good and is rooted in what conventional and lawful political orders honor and praise most highly. Second, it shows how nobility and beauty promise to satisfy the soul’s longing for the transcendent and the divine. Third, it shows that nobility must ultimately be understood in terms of the good, and especially in terms of the beneficial and the pleasant, but that men resist understanding nobility in those terms. Hence the dissertation uncovers the core of the tension between the conventional understanding of nobility and a rational understanding of nobility—or between what seems noblest to us and what’s actually good for us.

Year: 2023

description: This article demonstrates an alternative approach that uses global navigation satellite system (GNSS) Doppler measurements in a Kalman filter (KF) to improve the accuracy of GNSS smartphone positioning. The proposed method automates the process of estimating the uncertainty of the dynamics model of the system, which is still a challenge for the conventional KF-based GNSS positioning methods that require heuristic tuning. Automation of dynamics model uncertainty estimation also demonstrates notable improvement in GNSS outlier detection or fault detection and exclusion. In addition, this article will perform a quality assessment of the GNSS observations obtained from two Android smartphones and investigate the performance of the proposed method when using GPS L1 + Galileo E1 signals compared to GPS L5 + Galileo E5a signals.

Thermodynamic Investigation of Solar-Assisted Heat Pumps for Water Heating Applications in Cold Climatic Conditions

description: In this thesis, the annual energy use, exergy, environmental, and economic performance of a direct-expansion solar-assisted heat pump (DX-SAHP) and a dual-source (solar/air) indirect-expansion solar-assisted heat pump (IDX-SAHP) for water heating under cold climatic conditions of Calgary, Alberta, is investigated. Also, the thermodynamic performance of the DX-SAHP system operating with various low global warming potential (GWP) refrigerants is evaluated. A mathematical model based on the fundamentals of thermodynamics and heat transfer is developed, validated, and implemented in MATLAB®. CoolProp®, a MATLAB® addon, was used to determine the required refrigerant properties. Besides, a series of experiments were performed on a prototype DX-SAHP water heater in Calgary, Alberta. The results show that a DX-SAHP can supply domestic hot water for a typical Canadian household in Calgary throughout the year with the maximum and minimum monthly average COPs of 3.94 and 2.4, respectively. Compared to a conventional ASHP and an electric water heater, the energy consumption of the system was reduced by 25% and 62%, respectively. Moreover, using SAHP lowers CO2 emissions by 1283 kg/year when switching from gas water heaters to SAHPs, while the payback period of these systems is more than a decade. Among the investigated low GWP refrigerants, R1233zd achieves the highest COPs, whereas R32 shows the lowest COPs. The second-law analysis results indicate that the exergy efficiency of the heat pump water heaters reduces in summer. The ASHP obtained the highest monthly average exergy efficiencies, followed by the DX-SAHP and the dual-source IDX-SAHP. The test results of a 2.3 m2 DX-SAHP prototype in Calgary show that the system can heat 178 L of water on sunny days in winter and sunny and cloudy days in summer in 4.5, 3, and 3.5 hours, respectively. The average COP of the system varied from 3.0 to 3.44. However, the system showed a considerable degree of superheat during operation, which resulted in inefficient performance. The imperfect bonding between the collector plate and the serpentine tube is identified as the leading cause of this issue. This collector is being replaced with a professionally fabricated one in the next design.

description: We study the merger of black hole (BH)-neutron star (NS) binaries with a variety of BH spins aligned or anti-aligned with the orbital angular momentum, and with the mass ratio in the range MBH/MNS = 2--5, where MBH and MNS are the mass of the BH and NS, respectively. We model NS matter by systematically parametrized piecewise polytropic equations of state. The initial condition is computed in the puncture framework adopting an isolated horizon framework to estimate the BH spin and assuming an irrotational velocity field for the fluid inside the NS. Dynamical simulations are performed in full general relativity by an adaptive mesh refinement code, SACRA. The treatment of hydrodynamic equations and estimation of the disk mass are improved. We find that the NS is tidally disrupted irrespective of the mass ratio when the BH has a moderately large prograde spin, whereas only binaries with low mass ratios, MBH/MNS ~ 0.1 Msun, which is required by central engines of short gamma-ray bursts, if the BH spin is prograde. Information of the tidal disruption is reflected in a clear relation between the compactness of the NS and an appropriately defined "cutoff frequency" in the gravitational-wave spectrum, above which the spectrum damps exponentially. We find that the tidal disruption of the NS and excitation of the quasinormal mode of the remnant BH occur in a compatible manner in high mass-ratio binaries with the prograde BH spin. The correlation between the compactness and the cutoff frequency still holds for such cases. It is also suggested by extrapolation that the merger of an extremely spinning BH and an irrotational NS binary does not lead to formation of an overspinning BH.

description: When are nondemocracies more (or less) likely to make concessions in trade negotiations? The literature on negotiations suggests that nondemocracies are less cooperative than democratic regimes in signing trade agreements. However, some nondemocracies deviate from this expected behaviour. I evaluate the impact of regime type on concessions in free trade agreement (FTA) negotiations. I extend Putnam’s two-level games theory and argue that states’ win-set size in negotiations affects the concessions they make. Nondemocracies have wider win-sets than democracies because they have a less complex institutional structure with fewer checks and balances. Among nondemocracies, there is also significant variation in domestic institutional characteristics, specifically in the number of veto players. I propose that concessions are likely to vary systematically based on these institutional differences. I test my argument through two case studies, the Turkey-Chile FTA and the Turkey-Egypt FTA. I introduce a new measurement for concessions using tariff-related and non-tariff concessions. In particular, my measurement of non-tariff concessions is based on the parties’ previous trade policy practices, while the tariff-related concessions are assessed using the expected negotiation outcomes of the export-oriented and import-competing groups. I find that nondemocracies are more likely to make tariff-related and non-tariff concessions with democracies than other nondemocracies. I present additional evidence from the negotiation rounds and two interviews with former chief negotiators of Turkey and Chile to complement these results.

description: When Giacomo Puccini debuted his La fanciulla del West at New York’s Metropolitan Opera in 1910, he began the serious operatic engagement of the frontier West. Yet over a century since, the frontier West is a narrative space that has been engaged only sporadically by American and Canadian composers alike. Music drama of the frontier represents a niche corner of twentieth- and twenty-first century opera, one with compositional characteristics that distinguish it from other post-nineteenth century opera. The frontier West is both actual historiographic entity and imagistic concept. With the end of an actual frontier line in 1880, its recession into history brought recounting of memories from actual lived experiences, tainted and coloured by the passage of time and mixed together with artistically licenced renditions. Depictions of the West beginning in the nineteenth century established, then repeatedly reused, signifiers of time and place that created an easily recognizable imagistic space, one with stylized elements of setting, archetypical characters and expected broad story arcs. This exoticization of the West, the view of within from without, relies on markers or tropes of cultural difference from the normative culture that become readily identifiable characteristics of the artistic imagistic frontier. Mythicization of the West followed in symbolizing the exoticized frontier as representing various aspects of national identity (especially American identity), including rugged individualism and exceptionalism. This thesis examines four operas – Puccini’s La fanciulla del West (1910), Douglas Moore’s The Ballad of Baby Doe (1956), John Estacio’s Filumena (2003), and Allan Bell’s Turtle Wakes (2001) – for how each individually engages exoticism of the frontier with imagistic, mythological and musical codifications of the West in a manner that both extends late nineteenth-century romanticism and exoticism operatic practices and incorporates modernist musical elements.
Short-term effects of clear-cut harvesting on the export of fish food subsidies in high elevation headwater streams of interior British Columbia
Creators: name: Sorensen, Jacqueline Jody
Publisher: name: University of British Columbia
Year: 2012

description: I investigated the immediate effects of clear-cut logging on the export of invertebrates and organic matter from headwater streams by using a Before, After, Control, Impact, Paired series approach (BACIP). Seventeen high elevation streams within two study areas (Horsefly River and Eagle Lake) in the southern interior of British Columbia, Canada were sampled for drifting macro-invertebrates, fine particulate organic matter (FPOM), and dissolved organic carbon (DOC). Invertebrate drift was collected by diverting the entire stream flow through a 250 µm mesh drift net over a 24 hour period (in triplicate for a total of 72 hours), directly before and one year after logging. I compared differences between 10 clear-cut treatment and 7 control streams in terms of invertebrate drift biomass/abundance flux (mg 24 hrs-1and invertebrates 24 hrs⁻¹), invertebrate drift biomass/abundance density (mg m⁻³ and invertebrates m⁻³), and FPOM and DOC concentration and flux (mg L⁻¹ and mg 24 hrs⁻¹). In addition to total invertebrate export, biotic metrics in the form of composition measures, taxa richness and diversity were calculated to determine changes in the invertebrate drift community. In the pre-impact phase of this study, I found that headwater streams were productive exporters of invertebrates (18-5382 invertebrates 24hrs⁻¹) and organic matter (FPOM: 3-516 g 24hrs⁻¹, DOC: 105-1579 g 24hrs⁻¹). In the post-impact analysis, significant increases in total drifting invertebrate biomass and abundance flux were detected in clear-cut streams at Horsefly River. Additionally, community analysis of the drift composition showed significant changes in flux and density of Ephemeroptera (E), Plecoptera (P), Trichoptera (T) and Diptera (D). %EPT (ratio of EPT/total invertebrate abundance) was the only measure to indicate reduced abundance of sensitive taxa as a result of logging at both study areas. Significant changes in diversity were also observed at Eagle Lake. Overall, no significant responses in total flux or concentrations of FPOM and DOC were revealed. It is possible that seasonal and longer term annual monitoring may further define trends that were observed in the short term.

Women’s Experiences in the Colonial Justice System of Southern Nigeria, 1920 -1960

description: The law and criminal justice institutions are embodiments of a state’s authority to govern and punish erring subjects. This study highlights how southern Nigerian women navigated traditional versus colonial approaches to acts deemed criminal during a period of regime change. This micro-history of southern Nigerian women seeks to individualize their experiences within the framework of the criminal justice system by weaving a narrative of how these institutions deliberately and in other cases, unintentionally provoked the display of female agency in matters involving defiance, crime, and punishment. The stories of these women, culled from newspapers, archival documents, and court records reveal how they imagined, understood, and negotiated, their crimes when brought before institutions of the criminal justice system. Firstly, I examine how colonial institutions punished women for engaging in the non-violent crime of profiteering during World War II. At first glance, the actions of these accused women might be viewed merely as resistance to the intrusion of imperial law. However, a deeper analysis of this crime reveals how colonial institutions created conditions resulting in a collision between normative and legal orders in southern Nigeria. This study also reveals how the blanket term ‘profiteering’ camouflaged the involvement of women in other forms of crimes during this period. Secondly, in seeking to demystify the rather exclusive images of male-dominated violent crimes in Nigeria, this study also examines female-perpetrated homicide. Unlike profiteering, homicide had normative implications in both colonial and traditional cultures. Thus, I examine the changes and continuities in the punishment of women involved in this crime. I also focus on officials of the justice system and argue that because of their pertinent role in examining the cadaver of the victim and understanding the state of a woman’s mental and physical health, male medical witnesses began to play a significant role in determining the truthfulness of a woman’s words. However, a woman’s biological peculiarity, societal perceptions and a judge’s discretion based on his cultural understanding of a case mattered and were sometimes brought to the fore in the prosecution of female-perpetrated homicide. Overall, this study reveals a paradox of female experiences in the colonial justice institution, which sanctioned and punished women for their ‘crimes’ but sometimes created avenues for negotiation, compromise, and accommodation.

description: As planets form and grow within gaseous protoplanetary disks, the mutual gravitational interaction between the disk and planet leads to the exchange of angular momentum, and migration of the planet. We review current understanding of disk-planet interactions, focussing in particular on physical processes that determine the speed and direction of migration. We describe the evolution of low mass planets embedded in protoplanetary disks, and examine the influence of Lindblad and corotation torques as a function of the disk properties. The role of the disk in causing the evolution of eccentricities and inclinations is also discussed. We describe the rapid migration of intermediate mass planets that may occur as a runaway process, and examine the transition to gap formation and slower migration driven by the viscous evolution of the disk for massive planets. The roles and influence of disk self-gravity and magnetohydrodynamic turbulence are discussed in detail, as a function of the planet mass, as is the evolution of multiple planet systems. Finally, we address the question of how well global models of planetary formation that include migration are able to match observations of extrasolar planets.

description: My thesis describes the behaviour of subventricular zone (SVZ)-derived neural stem and progenitor cells (here called NPCs) from young adult mice during exposure to members of the platelet-derived growth factor (PDGF) family of ligands. Two novel findings arise from my work. First, P53 null NPCs cultured in PDGFA transform in vitro acquiring a phenotype and genotype that closing resembles that of human glioblastoma (GBM). Second, NPCs cultured in PDGFC form small quiescent spheres of pluripotential neural stem cells (NSCs) that can be maintained in a stem-like state in PDGFC or induced to proliferate or differentiate by modifying the growth factor environment. My work is of interest to cancer biologists studying the origins of GBM and oncologists seeking ways to prevent this cancer or intercept it at an early more treatable stage. My thesis is also of interest to stem cell biologists and neurobiologists seeking new models to study the stem cell niche in the mammalian brain and brain maturation in health and disease. I have uncovered the mechanism of transformation of P53 null NPCs in PDGFA by analyzing an in vitro model of oncogenesis in which the earliest events can be detected, and their consequences tracked over time. I discovered that defective mitosis initiates a series of events that culminate in a GBM-like cancer. I also discovered that cells isolated from the SVZ using PDGFC have the behavioral and biomarker profile that would be expected of true stem cells. My findings stand in contrast to the gold standard method for isolating and studying NSCs in which cells from the SVZ are cultured in epidermal growth factor plus fibroblast growth factor (EGF/FGF) and where they divide rapidly and continuously. I also found that PDGFC could replace PDGFA in the isolation and propagation of oligodendrocyte progenitor cells (OPCs), a cell type of increasing interest. Overall, my work adds to our understanding of the biology of two important members of the PDGF family of ligands and describes new model systems that can be exploited further.

description: During the past 20 years, the idea that non-spherical planetary nebulae (PN) may need a binary or planetary interaction to be shaped was discussed by various authors. It is now generally agreed that the varied morphologies of PN cannot be fully explained solely by single star evolution. Observationally, more binary central stars of planetary nebulae (CSPN) have been discovered, opening new possibilities to understand the connections between binarity and morphology. So far, \simeq 45 binary CSPN have been detected, most being close systems detected via flux variability. To determine the PN binary fraction, one needs a method to detect wider binaries. We present here recent results obtained with the various techniques described, concentrating on binary infrared excess observations aimed at detecting binaries of any separation.

description: Molecular outflows are expected to play an important role in galaxy evolution. However, direct evidence of such outflows at z>6 (epoch of reionization) has been limited. To search for outflow, we performed ALMA observations of the OH 119 um line toward J2054-0005, a luminous quasar at z=6.04. The OH line is detected and exhibits a P-Cygni profile with a broad, blue-shifted absorption, revealing unambiguous evidence of outflowing molecular gas. The mean and terminal outflow velocities, obtained from Gaussian fitting, are ~670 km/s and 1500 km/s. The mass outflow rate is found to be comparable to the star formation rate, indicating efficient quenching of star formation. We found that up to ~50% of the outflowing molecular gas may be able to escape the host galaxy and reach the intergalactic medium. This poster is based on Salak et al. (2023) (arXiv:2307.02104).

description: If $G$ and $H$ are two cubic graphs, then we write $H\prec G$, if $G$ admits a proper edge-coloring $f$ with edges of $H$, such that for each vertex $x$ of $G$, there is a vertex $y$ of $H$ with $f(\partial_G(x))=\partial_H(y)$. Let $P$ and $S$ be the Petersen graph and the Sylvester graph, respectively. In this paper, we introduce the Sylvester coloring conjecture. Moreover, we show that if $G$ is a connected bridgeless cubic graph with $G\prec P$, then $G=P$. Finally, if $G$ is a connected cubic graph with $G\prec S$, then $G=S$.

description: Homelessness is a serious violation of one’s dignity, and youth who are long-term shelter users are particularly vulnerable members of a vulnerable demographic. The commitment to prevent and eliminate homelessness, particularly among the youth, is a shared responsibility. Programmes aiming at providing homeless people with permanent housing, mostly identify people who have lived with the condition for an extended period of time for support. Allowing young people to be homeless for an extended period of time before intervening, exposes them to several kinds of hardships on the streets. Early identification of youth at risk of becoming a long term shelter user is a proactive and a more humane way of addressing the problem. Machine learning is brought forth as a tool to augment the expertise of shelter staff in identifying youth at risk of long-term shelter use. Machine learning algorithms are utilised to predict youth at risk of long-term shelter use with the clients’ first 30, 60, 90, 120, or 180 days of shelter access records. A real time program delivery approach was incorporated in the experiments as a supplement to existing other methods in fighting homelessness. Interpretable machine learning models capable of ultimately producing classification rules in DNF format are evaluated. The level of control over the complexity of the generated rules, coupled with statistical evaluation metrics are employed in the evaluation.
Ab-initio analysis of superstructures revealed by STM on bilayer graphene

description: In this work we performed density functional theory calculations for a twisted bilayer graphene (BLG). Several conmensurable rotation angles were analyzed and for each one a constant height mode STM image was obtained. These STM images, calculated under the Tersoff-Hamman theory, reproduce the main features experimentally observed, paticularly superstructures and giant corrugations. In this way we confirm that STM characterization of twisted BLG can produce superstructures whose tunneling current intensity maxima occur over regions with $AA$ stacking. Additionally we give new evidence in favour of an electronic origin for the superstructures instead another physical grounds.
Optimum Allocation of Transit Signal Priority Deployment Along a Transit Corridor: A Bilevel Optimization Approach

subject: Engineering--Civil

description: The central focus of this thesis is to develop a delay cost optimization model based on the cost of total person delay determining optimal Transit Signal Priority (TSP) configuration along a specified corridor based. The optimal configuration of TSP along a corridor allows for TSP to be implemented when it only provides cost benefits and reduces overall delay. Additionally, if there is an implementation or operation restriction for the number of intersections with TSP enabled then this optimization model allows for the immediate selection of the optimal locations. The TSP configuration model as a bilevel approach with the upper level expressed as a delay cost optimization model is a useful tool for current and future transit planning applications. It uses newly available data and provides thorough recommendations for the optimal configuration of TSP based on selected key performance indicators (KPIs) including threshold values for each intersection. The cost delay optimization model was developed to calculate the cost of delay as related to TSP implementation at each intersection along a corridor using KPIs were selected to represent all users of the corridor for peak hour flow, specifically current bus passengers, downstream waiting passengers, and other commuters driving private vehicles. The bilevel approach can be split into the upper-level delay cost optimization model and the lower-level VISSIM model. The upper-level delay cost optimization model may be used to evaluate each intersection along a corridor as to the efficacy of implementing total person delay TSP and is developed from selected KPIs. The cost delay optimization model to minimize delay of all users along a corridor was developed based on the selected KPIs as the input variables. The output of the delay cost optimization model is the configuration of TSP along the corridor which is then input into the VISSIM model during the bilevel approach.

Constraints on GUT 7-brane Topology in F-theory

description: We study the relation between phenomenological requirements and the topology of the surfaces that GUT 7-branes wrap in F-theory compactifications. In addition to the exotic matter free condition in the hypercharge flux scenario of SU(5)_{GUT} breaking, we analyze a new condition that comes from a discrete symmetry aligning the contributions to low-energy Yukawa matrices from a number of codimension-three singularity points. We see that the exotic matter free condition excludes Hirzebruch surfaces (except ${\mathbb F}_0$) as the GUT surface, correcting an existing proof in the literature. We further find that the discrete symmetry for the alignment of the Yukawa matrices excludes del Pezzo surfaces and a rational elliptic surface as the GUT surface. Therefore, some GUT 7-brane surfaces are good for some phenomenological requirements, but sometimes not for others, and this aspect should be kept in mind in geometry search in F-theory compactifications.
