description: We establish a near dichotomy between randomness and structure for the point counts of arbitrary projective cubic threefolds over finite fields. Certain "special" subvarieties, not unlike those in the Manin conjectures, dominate. We also prove new general results for projective hypersurfaces. Our work continues a line of inquiry initiated by Hooley.

description: Recent advances in imaging and machine learning have revolutionized both the acquisition and analysis of high-dimensional data. Unfortunately, these techniques have not been effectively exported to morphometrics, or the quantitative analysis of shape and form, which is central to biology and related disciplines for understanding phenotypic variation. Lack of implementations, different model systems and experimental designs, small sample sizes, and limited expertise continue to yield self-contained morphometric studies with unstandardized datasets that cannot be aggregated for increasingly powerful analyses. This dissertation presents heuristic and learning-based tools alongside big data resources for large-scale morphometrics. I begin by summarizing key morphometric paradigms, focusing on data acquisition, aggregation, and classification. Next, I develop an automated landmarking and shape optimization pipeline based on image registration and artificial neural networks. After demonstrating its efficacy, I use this phenotyping framework to build MusMorph, a database of mouse morphology data (N=10,056) containing anatomical atlases, aligned micro-computed tomography images, landmark configurations, and segmentations spanning numerous strain/genotype combinations and developmental stages. Finally, I introduce the R package pheble to perform a meta-analysis of learning-based classification algorithms across high-dimensional phenotypic datasets ranging in organismal family and anatomy. My analysis shows how ensemble learning, or combining predictions from individual learners, can maximize classification performance whilst being data agnostic. Altogether, these studies represent tools and resources that can accelerate, standardize, and augment morphometric analyses for novel phenomic inquiries.

description: Searching for alternative ways to involve students in academic integrity work is fundamental to maintaining trust and protecting educational institutions’ integrity; this quest is especially relevant now with the emergence of technologies that facilitate cheating (Dawson, 2020; Kumar et al., 2022; Lancaster & Cotarlan, 2021). Three authors from diverse fields (i.e., academic integrity, Scholarship of Teaching and Learning, and social learning) engaged in transdisciplinary reflections through Restorative Practices (RP) proactive circles to address this interest. This presentation provides insight into the conceptual underpinnings that inform understanding of Students as Partners (SaP) in academic integrity work from an Epistemologies of the South lens. This presentation also addresses the implementation of RP proactive restorative circles to pursue academic integrity interests collectively. Participants attending this presentation will gain insight into the interconnections between the concepts of SaP, the Systems Approach to Academic Integrity, and the Epistemologies of the South, discuss recommendations developed by the authors and built from RP proactive circles, and analyze how these circles might help reflect on academic integrity at large.
A Feminist-Driven Computational Urban Design Framework for Mapping Gender-Inclusive Urban Places

Year: 2023

description: A significant hurdle to employing data-driven and computational methods in urban design for people-place relation analysis is when the research is driven not by in-depth knowledge and theory of the field, but by data, which could lead to data autocracy. This paper aims to develop a feminist-driven framework for computational urban design to map, measure, and analyze gender-inclusive features of urban places. The framework suggests that data requirements for a computational urban design assessment need to be initially determined from domain theory patterns. The results demonstrate that the integration of multi-type, multi-scale, and multi-source datasets is needed to address all gender-inclusive features of urban places. Finally, we conclude that by adopting a theory-driven approach, it is possible to define a research system through which the re-searcher can control the data flow, guide the research path, and benefit from opportunities of geospatial big data and data-driven methods for conducting computational urban design.

description: We examine the critical behaviour of a lattice model of tumor growth where supplied nutrients are correlated with the distribution of tumor cells. Our results support the previous report (Ferreira et al., Phys. Rev. E 85, 010901 (2012)), which suggested that the critical behaviour of the model differs from the expected Directed Percolation (DP) universality class. Surprisingly, only some of the critical exponents (beta, alpha, nu_perp, and z) take non-DP values while some others (beta', nu_||, and spreading-dynamics exponents Theta, delta, z') remain very close to their DP counterparts. The obtained exponents satisfy the scaling relations beta=alpha*nu_||, beta'=delta*nu_||, and the generalized hyperscaling relation Theta+alpha+delta=d/z, where the dynamical exponent z is, however, used instead of the spreading exponent z'. Both in d=1 and d=2 versions of our model, the exponent beta most likely takes the mean-field value beta=1, and we speculate that it might be due to the roulette-wheel selection, which is used to choose the site to supply a nutrient.

description: We discuss three examples of bimolecular mass-action systems with three species, due to Feinberg, Berner, Heinrich, and Wilhelm. Each system has a unique positive equilibrium which is unstable for certain rate constants and then exhibits stable limit cycles, but no chaotic behaviour. For some rate constants in the Feinberg--Berner system, a stable equilibrium, an unstabe limit cycle, and a stable limit cycle coexist. All three networks are minimal in some sense. By way of homogenising the above three examples, we construct bimolecular mass-conserving mass-action systems with four species that admit a stable limit cycle. The homogenised Feinberg--Berner system and the homogenised Wilhelm--Heinrich system admit the coexistence of a stable equilibrium, an unstable limit cycle, and a stable limit cycle.
A constrained proof of the strong version of the Eshelby conjecture for the three-dimensional isotropic medium

description: Eshelby's seminal work on the ellipsoidal inclusion problem leads to the conjecture that the ellipsoid is the only inclusion possessing the uniformity property that a uniform eigenstrain is transformed into a uniform elastic strain. For the three-dimensional isotropic medium, the weak version of the Eshelby conjecture has been substantiated. The previous work of Ammari et al. substantiates the strong version of the Eshelby conjecture for the cases when the three eigenvalues of the eigenstress are distinct or all the same, whereas the case where two of the eigenvalues of the eigenstress are identical and the other one is distinct remains a difficult problem. In this work, we study the latter case. To this end, firstly, we present and prove a necessary condition for a convex inclusion being capable of transforming a single uniform eigenstress into a uniform elastic stress field. Since the necessary condition is not enough to determine the shape of the inclusion, secondly, we introduce a constraint that is concerned with the material parameters, and prove that there exist combinations of the elastic tensors and uniform eigenstresses such that only an ellipsoid can have the Eshelby uniformity property for these combinations simultaneously. Finally, we provide a more specifically constrained proof of the conjecture by proving that for the uniform strain fields constrained to that induced by an ellipsoid from a set of specified uniform eigenstresses, the strong version of the Eshelby conjecture is true for a set of isotropic elastic tensors which are associated with the specified uniform eigenstresses. This work makes some progress towards the complete solution of the intriguing and longstanding Eshelby conjecture for three-dimensional isotropic media.

description: Building on previous research of Chi and Chi (2022), the current paper revisits estimation in robust structured regression under the $\text{L}_2\text{E}$ criterion. We adopt the majorization-minimization (MM) principle to design a new algorithm for updating the vector of regression coefficients. Our sharp majorization achieves faster convergence than the previous alternating proximal gradient descent algorithm (Chi and Chi, 2022). In addition, we reparameterize the model by substituting precision for scale and estimate precision via a modified Newton's method. This simplifies and accelerates overall estimation. We also introduce distance-to-set penalties to allow constrained estimation under nonconvex constraint sets. This tactic also improves performance in coefficient estimation and structure recovery. Finally, we demonstrate the merits of our improved tactics through a rich set of simulation examples and a real data application.

description: We examine the momentum-dependent excitation spectra of indirect as well as direct resonant inelastic x-ray scattering (RIXS) processes in half-filled (extended) Hubbard rings. We determine the fundamental features of the groundstate RIXS response and discuss the experimental conditions that can allow for the low-energy part of these features to be distinguished in one-dimensional copper-oxide materials, focusing particularly on the different magnetic excitations occurring in indirect and direct RIXS processes. We study the dependence of spin and charge excitations on the choice of and detuning from resonance. Moreover, final state excitation weights are calculated as a function of the core-hole potential strength and lifetime. We show that these results can be used to determine material characteristics, such as the core-hole properties, from RIXS measurements.

description: We study the kick dynamics of periodically driven quantum systems, and provide a timeindependent effective Hamiltonian with the analytical form to reasonably describe the effective dynamics in a long timescale. It is shown that the effective coupling strength can be much larger than the coupling strength of the original system in some parameter regions, which stems from the zero time duration of kicks. Furthermore, different regimes can be transformed from and to each other in the same three-level system by only modulating the period of periodic kicks. In particular, the population of excited states can be selectively suppressed in periodic kicks, benefiting from the large detuning regime of the original system. Finally, some applications and physical implementation of periodic kicks are demonstrated in quantum systems. Those unique features would make periodic kicks becoming a powerful tool for quantum state engineering.
Secondary and Tertiary Prevention for Adolescent Dating Violence: A Systematic Review

Subjects: subject: Psychology--Clinical

description: Adolescent dating violence (ADV) is a pervasive public health issue associated with numerous mental, social, psychological, and physical health consequences. Thus, prevention programs have been implemented to prevent this violence and promote healthy relationships. Although there is a growing body of literature on primary ADV prevention strategies, little is known about secondary and tertiary ADV prevention approaches. Thus, this systematic review, guided by Cochrane Review methodology, summarizes available evidence on secondary and tertiary ADV prevention programs. The search with no date restriction was conducted in 8 databases in November 2022. Studies published in English and/or Spanish were included if they described the development, adaptation, implementation, and/or evaluation of a secondary and/or tertiary preventive intervention for ADV. After screening the title and abstract of 3645 articles, 31 articles were included in this study, which report on 14 secondary and 1 tertiary intervention. The included studies suggest that these secondary interventions are somewhat effective in preventing ADV victimization and perpetration, and that the effects may be strongest for teens with a higher risk of being involved in an abusive relationship. The only included study that reported on a tertiary intervention was a developmental study. Based on the lack of tertiary intervention implemented in our communities, clinical-focused interventions focusing on treating and reducing negative symptoms of ADV are needed.

description: Dynamics of S=1 antiferromagnetic bond-alternating chains in the dimer phase, in the vicinity of the critical point with the Haldane phase, is studied by a field theoretical method. This model is considered to represent the compound Ni(C$_9$H$_{24}$N$_4$)(NO$_2$)ClO$_4$ (abbreviated as NTENP). We construct the sine-Gordon (SG) field theory as a low-energy effective model of this system, starting from a Tomonaga-Luttinger liquid at the critical point. Using the exact solution of the SG theory, we give a field theoretical picture of the low-energy excitation spectrum of NTENP. Results derived from our picture are in a good agreement with results of inelastic neutron scattering experiments on NTENP and numerical calculation of the dynamical structure factor. Furthermore, on the basis of the obtained theoretical picture, we predict that the sharp peaks correspond to a single elementary excitation are absent in the Raman scattering spectrum of NTENP in contrast to the inelastic neutron scattering spectrum.

description: This study explores the employment experiences of women who work in the tents during the Calgary Stampede. The findings are drawn from a total of eight qualitative interviews. The data suggest that the women who work in the tents occupy roles that are highly feminized and sexualized. The three main findings of this thesis suggest: first, that the women who were interviewed performed their work within the patriarchal arena of the Calgary Stampede which allows the workers to dismiss the frequently inappropriate behaviour of patrons; second, that the participants operated under a rhetoric of choice which impacted their work experience; and, third, that the distinction the participants made between their work performance and that of “other girls” provided a way that the women made sense of their work.

LIGHT CURVE SIMULATION AND SHAPE INVERSION FOR HUMAN-MADE SPACE OBJECTS

Publisher: name: Purdue University Graduate School
Year: 2023
Subjects: classificationCode: 510901
subject: Astrodynamics and space situational awareness

description: Characterizing unknown space objects is an important component of robust space situational awareness. Estimating the shape of an object allows analysts to perform more accurate orbit propagation, probability of collision, and inference analysis about the object’s origin. Due to the sheer distance from the camera combined with diffraction and atmospheric ef- fects, most resident space objects of interest are unresolved when observed from the ground with electro-optical sensors. State of the art techniques for object characterization often rely on light curves — the time history of the object’s observed brightness. The brightness of the object is a function of the object’s shape, material properties, attitude profile, as well as the observation geometry. The process of measuring real light curves is complex, involv- ing the physics of the object, the sensor, and the background environment. The process of recovering shape information from brightness measurements is known as the light curve shape inversion problem. This problem is ill-posed without further assumptions: modern direct shape inversion methods require that the attitude profile and material properties of the object is known, or at least can be hypothesized. This work describes improvements to light curve simulation that faithfully model the environmental and sensor effects present in true light curves, yielding synthetic measurements with more accurate noise characteris- tics. Having access to more accurate light curves is important for developing and validating light curve inversion methods. This work also presents new methods for direct shape inver- sion for convex and nonconvex objects with realistic measurement noise. In particular, this work finds that improvements to the convex shape inversion process produce more accurate, sparser geometry in less time. The proposed nonconvex shape inversion method is effective at resolving singular large concave feature.
The Latter-day Saint Talk as an I-Thou Relational Event

description: Suspicion of religion is prevalent in modern culture, but many people seem to find meaning and purpose through active participation in a religious community. Is creative growth possible for individuals who adhere to faith traditions? How does the tension between personal autonomy and institutional authority, particularly in a hierarchical church, play out in a way that facilitates opportunity for genuine dialogue? To explore these questions, I focus on a specific practice of The Church of Jesus Christ of Latter-day Saints, i.e., the talk. This understudied phenomenon, which involves lay members instructing one another, warrants more attention. I leverage the philosophical hermeneutics of Hans Georg Gadamer, particularly his concept of play [Spiel] to study how the rules of giving talks are set and practiced within the hierarchical structure of the church. I argue that there is space for genuine creativity for participants within these boundaries. To address the experiential possibilities for transcendent religious experience in this space, I rely on Martin Buber’s writings on community to provide a framework for the 'suprasensual' knowledge that can be gained (Buber 2016, 8). Buber argues that transformational relationships are facilitated through community as people move from I-It encounters into I-Thou relations through dialogue. I conceptually analyze talks from the highest-ranking leaders of the church, in addition to four representative talks given by local church members. My study develops a hermeneutic for how to recover a more nuanced understanding of the role of religious organizations as a place where the purported experience of transcendence is mediated through community and in doing so fills a gap in the scholarship of the Latter-day Saints.

description: This research studies graph-based approaches for Answer Sentence Selection (AS2), an essential component for retrieval-based Question Answering (QA) systems. During offline learning, our model constructs a small-scale relevant training graph per question in an unsupervised manner, and integrates with Graph Neural Networks. Graph nodes are question sentence to answer sentence pairs. We train and integrate state-of-the-art (SOTA) models for computing scores between question-question, question-answer, and answer-answer pairs, and use thresholding on relevance scores for creating graph edges. Online inference is then performed to solve the AS2 task on unseen queries. Experiments on two well-known academic benchmarks and a real-world dataset show that our approach consistently outperforms SOTA QA baseline models.
VHS 2.0 : amateur archiving on the internet and the nostalgic reclamation of retro media
Creators: name: Sorrenti, Dax
Publisher: name: University of British Columbia
Year: 2012

description: The archiving of retro media on the internet has become one of the more prolific examples of amateur archiving in recent years. Using various case studies, I argue for a new understanding of how this orphaned and obsolete media preserves important nostalgic and cultural histories. Not only this, but the preservation of niche film and television programming deserves recognition for the intricate and complex work of amateur archivists, in the aims of validating their work and viewing the sharing of this material as more than simple file sharing. Often providing the only means by which to access material, these archival sites preserve history through its media output, and I provide a glimpse into the motivations and machinations of their inner workings. In need of protection from legal prosecution, and lacking a clear understanding of their place amongst contemporary media in the mainstream, I argue for a nostalgic reclamation of this material, that can co-exist alongside other media with little to no harm.
Symmetry as a shadow of topological order and a derivation of topological holographic principle

description: Symmetry is usually defined via transformations described by a (higher) group. But a symmetry really corresponds to an algebra of local symmetric operators, which directly constrains the properties of the system. In this paper, we point out that the algebra of local symmetric operators contains a special class of extended operators -- transparent patch operators, which reveal the selection sectors and hence the corresponding symmetry. The algebra of those transparent patch operators in $n$-dimensional space gives rise to a non-degenerate braided fusion $n$-category, which happens to describe a topological order in one higher dimension (for finite symmetry). Such a holographic theory not only describes (higher) symmetries, it also describes anomalous (higher) symmetries, non-invertible (higher) symmetries (also known as algebraic higher symmetries), and non-invertible gravitational anomalies. Thus, topological order in one higher dimension, replacing group, provides a unified and systematic description of the above generalized symmetries. This is referred to symmetry/topological-order (Symm/TO) correspondence. Our approach also leads to a derivation of topological holographic principle: \emph{boundary uniquely determines the bulk}, or more precisely, the algebra of local boundary operators uniquely determines the bulk topological order. As an application of the Symm/TO correspondence, we show the equivalence between $\mathbb{Z}_2\times \mathbb{Z}_2$ symmetry with mixed anomaly and $\mathbb{Z}_4$ symmetry, as well as between many other symmetries, in 1-dimensional space.

description: Community detection, the process of identifying module structures in complex systems represented on networks, is an effective tool in various fields of science. The map equation, which is an information-theoretic framework based on the random walk on a network, is a particularly popular community detection method. Despite its outstanding performance in many applications, the inner workings of the map equation have not been thoroughly studied. Herein, we revisit the original formulation of the map equation and address the existence of its ``raw form,'' which we refer to as the single-trajectory map equation. This raw form sheds light on many details behind the principle of the map equation that are hidden in the steady-state limit of the random walk. Most importantly, the single-trajectory map equation provides a more balanced community structure, naturally reducing the tendency of the overfitting phenomenon in the map equation.

description: The electrical resistivity rho_c of the underdoped cuprate superconductor YBCO was measured perpendicular to the CuO_2 planes on ultra-high quality single crystals in magnetic fields large enough to suppress superconductivity. The incoherent insulating-like behavior of rho_c at high temperature, characteristic of all underdoped cuprates, is found to cross over to a coherent regime of metallic behavior at low temperature. This crossover coincides with the emergence of the small electron pocket detected in the Fermi surface of YBCO via quantum oscillations, the Hall and Seebeck coefficients and with the detection of a unidirectional modulation of the charge density as seen by high-field NMR measurements. The low coherence temperature is quantitatively consistent with the small hopping integral t_perp inferred from the splitting of the quantum oscillation frequencies. We conclude that the Fermi-surface reconstruction in YBCO at dopings from p = 0.08 to at least p = 0.15, attributed to stripe order, produces a metallic state with 3D coherence deep in the underdoped regime.

description: Spatial reasoning is a critical skill for learning mathematics, yet efforts to improve high school students' spatial reasoning skills within mathematics classrooms are limited or absent in Ghana. This study aimed to investigate the impact of using dynamic and static visualization approaches within the Experience-Language-Pictorial-Symbolic-Application (ELPSA) pedagogical framework to teach geometry transformation concepts and enhance students’ spatial reasoning skills and geometry transformation knowledge during a four-week intervention. Due to the mixed results regarding the type of visualizations, the study also aimed to compare the effects of dynamic versus static visualization. The study used a one group pretest-post-test design to compare the effects of dynamic versus static visualization instruction. Seventy-seven (77) students from a single school participated in the study and were purposively assigned to either the dynamic (n = 35) or static (n = 42) group. The intervention lasted for four weeks (16 hours), and the dynamic group received dynamic visualization instruction, while the static group received static visualization instruction. The students' spatial reasoning skills and geometry transformation knowledge were assessed using a spatial reasoning instruction and geometry transformation achievement test before and after the intervention. Although there were no significant differences between the groups, both visualization approaches significantly improved students' spatial reasoning skills, including mental rotation, spatial orientation, and spatial visualization, as well as their geometry transformation knowledge. Additionally, the study found a positive relationship between students' geometry transformation scores and their spatial reasoning scores, suggesting that an ELPSA pedagogical approach to visualization instructions can enhance students' spatial reasoning skills within the context of geometry transformation. Overall, these findings have important implications for mathematics educators and curriculum developers, as the findings provide conclusive evidence that targeted geometry transformation instruction within ELPSA pedagogical framework can enhance students' spatial reasoning skills, regardless of the type of visualization used to teach geometry transformation.

description: AbstractThis paper examines the distribution channels structure as well as the underlying factors influencing the most prominent channel choices within the adventure tourism industry. It is based on in‐depth interviews with adventure tourism operators in Queenstown, New Zealand. The findings suggest that the distribution structure is similar to other attraction sectors and that business size has some bearing on the ‘length’ of the distribution chains. However, regardless of business size, the sector places a clear priority on ‘at destination’ distribution, and the factors underlying this choice were found to be varied and reflective of both sector‐specific demand and supply characteristics.

description: Treatment specific survival curves are an important tool to illustrate the treatment effect in studies with time-to-event outcomes. In non-randomized studies, unadjusted estimates can lead to biased depictions due to confounding. Multiple methods to adjust survival curves for confounders exist. However, it is currently unclear which method is the most appropriate in which situation. Our goal is to compare forms of Inverse Probability of Treatment Weighting, the G-Formula, Propensity Score Matching, Empirical Likelihood Estimation and augmented estimators as well as their pseudo-values based counterparts in different scenarios with a focus on their bias and goodness-of-fit. We provide a short review of all methods and illustrate their usage by contrasting the survival of smokers and non-smokers, using data from the German Epidemiological Trial on Ankle-Brachial-Index. Subsequently, we compare the methods using a Monte-Carlo simulation. We consider scenarios in which correctly or incorrectly specified models for describing the treatment assignment and the time-to-event outcome are used with varying sample sizes. The bias and goodness-of-fit is determined by taking the entire survival curve into account. When used properly, all methods showed no systematic bias in medium to large samples. Cox regression based methods, however, showed systematic bias in small samples. The goodness-of-fit varied greatly between different methods and scenarios. Methods utilizing an outcome model were more efficient than other techniques, while augmented estimators using an additional treatment assignment model were unbiased when either model was correct with a goodness-of-fit comparable to other methods. These doubly-robust methods have important advantages in every considered scenario.

description: Purpose – This paper seeks to analyze the extent to which New Zealand domestic and outbound travelers' book components of their trip in advance or at their destination and to explore the factors that influence this. Furthermore, the paper compares the distribution channels used by domestic and outbound travelers to purchase different travel products and to examine why these channels have been selected. Design/methodology/approach – The study involves the collection and analysis of data on the profiles, trip characteristics and distribution behavior of domestic and outbound travelers based on a nationwide telephone survey of 1,000 respondents. Findings – Little variation was found in the profile characteristics of domestic and outbound travelers but significant differences occurred in terms of the trip characteristics, the extent of booking in advance and at the destination, reasons why advance bookings were not made, how bookings were made and the channels used all exhibited significant differences according to domestic or outbound travel. This pattern was less consistent with regards to the factors influencing how the bookings were made and the factors affecting channel choice. Research and practical implications – The findings illustrate the complexity of travel decision-making issues, underline the need to take account of differences between domestic and outbound travel and across trip components, and to examine the factors that underlie distribution related behavior. Originality/value – The value and originality of this paper lie in the systematic comparison of the booking and channel choice behavior of domestic and outbound travelers, the search for factors influencing this behavior and a sectoral approach that differentiates transport to and at the destination. © 2011, Emerald Group Publishing Limited

description: A feasible mechanism of unitarization of amplitudes of deep inelastic scattering at small values of Bjorken $x$ is the gluon fusion. However, its efficiency depends crucially on the vacuum color screening effect which accompanies the multiplication and the diffusion of BFKL gluons from small to large distances. From the fits to lattice data on field strength correlators the propagation length of perturbative gluons is $R_c\simeq 0.2-0.3$ fermi. The probability to find a perturbative gluon with short propagation length at large distances is suppressed exponentially. It changes the pattern of (dif)fusion dramatically. The magnitude of the fusion effect appears to be controlled by the new dimensionless parameter $\sim R_c^2/8B$, with the diffraction cone slope $B$ standing for the characteristic size of the interaction region. It should slowly $\propto 1/\ln Q^2$ decrease at large $Q^2$. Smallness of the ratio $R_c^2/8B$ makes the non-linear effects rather weak even at lowest Bjorken $x$ available at HERA. We report the results of our studies of the non-linear BFKL equation which has been generalized to incorporate the running coupling and the screening radius $R_c$ as the infrared regulator.

description: With the aim of studying rotating quark-gluon plasma (QGP), holographically, from a top-down approach, the study of the effect of rotation on the deconfinement temperature of thermal QCD-like theories at intermediate coupling from ${\cal M}$-theory was missing in the literature. This paper fills this gap. The gravity dual includes a rotating cylindrical black hole. In the presence of rotation, from a semi-classical computation, we found that the deconfinement temperature is inversely proportional to the Lorentz factor, which suggests that the deconfinement temperature decreases with the increase of rotation. Further, we found that in the small angular velocity limit, results from higher derivative correction at ${\cal O}(R^4)$ do not change and are the same as in arXiv:2108.05372. The "UV-IR mixing", "Flavor Memory" effect, and "non-renormalization of $T_c$" in the ${\cal M}$-theory dual are similar to the ones observed in arXiv:2108.05372.

description: In the modern management, there are criteria for the correct setting of goals and tasks, such as: specificity, measurability, achievability and relevance of the goal, as well as its time-bound. This technique for the goal setting is called the SMART-model. The article investigates the history of smart-goals definition and the use of SMART-technique is a modern approach to setting operative goals. The smart-goal setting system allows, at the stage of targeting, to summarize all available information, establish the acceptable work period, determine the sufficiency of resources, and provide all participants in the process with clear, precise and specific tasks. SMART is an abbreviation, for which there exists the following definition: Specific, Measurable, Achievable, Relevant, and Time-bound. Each letter of the abbreviation SMART means a criterion for the effectiveness of the goals set. The SMART-methodology helps to correctly determine the criteria for setting goals, and teaches the skills to break goals into tasks and action items, as well as to include them in the calendar plan, skills to control over the achievement of such goals, skills to delegate, techniques of the effective communication and feedback, skills to determine and use areas of responsibility, and methods to sort out and comply with priorities. The application of the SMART-technique for setting goals can really be called strategic, since it allows setting achievable and understandable goals within the framework of the more global development strategy, as well as ensuring their achievement and continuity being in constant contact with the world through the properly-built feedback and flexible responsive system to rapidly changing external conditions

description: Obtaining an accurate and comprehensive representation of structural variation is crucial for understanding how large alterations in chromosome structure contribute to phenotype diversity and drive genome evolution. Despite continuous efforts into improving methods for identifying structural variation from whole genome sequencing data, accurate variant calling remains challenging. The barriers to progress in this area are complex and multifactorial but the technical limitations of short-read sequencing technologies and limited availability of suitable benchmarking resources for non-human species feature prominently. This thesis includes an in-depth evaluation of several commonly used tools for identifying structural variants from short- and long-read DNA sequencing data from natural Caenorhabditis elegans strains. The results of these comparisons revealed that popular tools yield considerably different results, which are described in detail in Chapter 2. A major aim of this project was to identify sources of error and variability that tool developers could address in the future. Surprisingly, the order of reads in PacBio FASTQ files were revealed to affect the predicted structural variants. Chapter 3 describes these results and demonstrates how alignment sorting algorithms contribute to the problem. In Chapter 4, an analysis of structural variation in 14 natural C. elegans strains is described. Importantly, this work demonstrates how long-read DNA sequencing data can be successfully used to identify structural variants at the population level.
