Molecular investigation of anticancer genes
Creators: name: Masood, Motasim
Publisher: name: Imperial College London
Year: 2019

description: The lack of specificity of the therapeutic agents against cancer is one of the prime obstacles in developing effective therapies for the disease. The specificity of chemotherapeutic agents against cancer cells is primarily quantitative rather than qualitative. Despite the earlier success of targeted therapies, it is now clear that among an unselected population of patients, the response rate is usually limited to 10-20%. Further avenues need to be explored for the development of cancer-specific therapies. A recent concept towards such efforts is that of anticancer genes. When ectopically overexpressed, anticancer genes specifically destroy tumour cells without harming normal cells. The examples include TRAIL, MDA7, PAR4, apoptin and Orctl3. In addition, 22 novel anticancer genes were identified through systematic functional genetic screening. This thesis aimed at (i) deciphering the identity of these genes, (ii) investigating their regulation and (iii) exploring the mechanisms behind their cancer specific actions. Sanger sequencing and subsequent analyses revealed that these 22 novel anticancer genes included non-coding RNAs, novel transcripts and protein-coding genes, two among the latter are TMEFF2 and FBLN5. The expression levels of both these genes exhibit a positive correlation with the survival of breast cancer patients and both are positively regulated by FOXO3 in MCF-7 cells. FBLN5 and TMEFF2 cause cell death selectively in the COS-7 cells and not in their untransformed counterparts (CV-1 cells). Mechanistic gene expression profiling and elaborate comparison pathways analyses uncovered that FBLN5 undertakes this action putatively through the downregulation of the downstream targets of MYC and inhibition of oxidative phosphorylation. Additionally, TMEFF2 causes caspase-dependent and p53-independent apoptosis in MCF-7 cells. Gene expression profiling revealed that the TMEFF2 induces potent interferon signalling along with the upregulation of TRAIL in MCF-7 cells. TMEFF2 gives a perinuclear punctate cytoplasmic appearance in MCF-7 cells and does not co-localize with either mitochondria or α-tubulin.
SOCIOECONOMIC STATUS AND PSYCHOLOGICAL DISTRESS AMONG WORKING-AGED AFRICAN AMERICANS

description: Researchers have consistently observed that high socioeconomic status (SES) is a fundamental cause of favorable mental and physical health outcomes among whites. Whether and how SES shapes the mental health of African Americans, however, remains unclear. Guided by a novel conceptual model, this study uses a sample of working-aged African Americans (n=776) from the Detroit Neighborhood Health Study to examine the relationship between several measures of SES with depression and anxiety, and the mechanisms that explain these relationships. Findings provide minimal support for SES as a strong predictor of mental health among African Americans in the Detroit context and suggest that other mechanisms, such as stressful or traumatic events, may be more important predictors of psychological distress among this sociodemographic group. This study adds to a growing body of literature indicating that structural factors considered to be fundamental causes of disease among whites may not operate similarly for racial-ethnic subpopulations.
12-lead Electrocardiogram Interpretation Competencies for All Graduating Medical Students: A Delphi Study
Creators: name: Fisher, Kathryn M
Publisher: name: University of Illinois at Chicago
Year: 2023

description: Lack of physician competence in 12-lead electrocardiogram (ECG) interpretation can lead to adverse patient outcomes. Despite widespread diagnostic use, no standardized training or assessment exists for medical students regarding ECG interpretation in the United States. Previous studies lack agreement on standardized competencies for graduating medical students (GMS) on ECG interpretation at the transition to residency. We aim to determine ECG interpretation competencies important for all GMS. A modified Delphi methodology was used to determine ECG findings that students should be able to identify on ECG and findings they should be able to identify as requiring urgent or emergent attention, per Association of American Medical Colleges (AAMC) Entrustable Professional Activity (EPA) 10. This included an initial literature review to determine a candidate list of ECG findings that was distributed to a multi-disciplinary national panel of 23 medical education experts, and advanced through iterative rounds to create a final list. Experts agreed on 21 specific ECG findings all GMS should be required to be able to interpret regardless of intended specialty. Eight were found to be important for all GMS to be able to identify as requiring urgent or emergent attention. Respondents agreed students must be competent in fundamentals of ECG interpretation and know the indications for cardiac monitoring and obtaining a ECG. This study provides a content blueprint for standardized curricula and assessment tools defining competencies related to ECG interpretation in GMS at the transition to residency point. It integrates the EPA framework as it relates to identification and stabilization of emergent findings to promote patient safety. Future efforts should focus on creating ECG curricula utilizing these content guidelines and standardized assessment tools to ensure all students at the Undergraduate Medical Education (UME) to Graduate Medical Education (GME) transition are prepared to safely interpret ECGs.
Hydrocarbon source and migration pathway identification through basin & petroleum systems modelling and mineral magnetism: a case study on the Beatrice Field, Inner Moray Firth, UK North Sea
Creators: name: Perkins, Joe
Publisher: name: Imperial College London
Year: 2022

description: This research builds on past studies analysing the relationship between the presence, formation and alteration of magnetic minerals with hydrocarbons, by investigating the poorly understood petroleum system of the Inner Moray Firth. This research shows that the Inner Moray Firth differs from the Central North Sea through both its petroleum system and its magnetic mineral assemblage. Magnetic mineral analysis provides extensive evidence of magnetite, goethite and siderite, alongside more minor lepidocrocite and iron sulphides, differing from the iron sulphide-rich magnetic mineral assemblages of the Central North Sea. Furthermore, this research shows two magnetic mineral behaviours around oil-water contacts in wells of the Inner Moray Firth, resulting from varying magnetic mineralogy. Most wells show continuous presence of goethite, which alters into magnetite towards the oil-water contacts, creating a strong magnetic enhancement directly below the contact. In contrast, wells bearing extensive iron sulphides experience magnetic enhancement directly above the oil-water contact, produced by the iron sulphides. Basin and petroleum systems modelling shows basin-wide maturity of Type I, Devonian-age and Type II-III Mid Jurassic-age source rocks, whilst dispelling the hypothesis of extensive Kimmeridge Clay Formation-sourced hydrocarbons, due to limited maturation. Modelling shows evidence of wide-spread lateral and vertical hydrocarbon migration, and that extensive faulting, alongside the late-stage, Cenozoic tilting of the basin, combine to heavily constrain and drastically reduce the trapping success of the petroleum system. Connections between the magnetic mineral analysis and modelling shows direct correlations between vertical migration and siderite presence, alongside the preferential formation of iron sulphides over other magnetic minerals when sulphur is present. When sulphur is not present, magnetite typically forms through the alteration of goethite around oil-water contacts. Furthermore, this study has shown direct connections between iron sulphide presence and Type II source rocks, and between iron hydroxide presence and Type I and Type II-III source rocks.

description: In this study we aim to explore how person factors interact with the dimensions of the Appraisal Model of Criminal Decision Making. Participants are presented with short vignettes which describe opportunities for dissexual behavior. Participants are asked to indicate the probability of whether they would take the opportunity or not on a scale from 0% to 100%. Based on a previous judgement study, an appraisal profile across the six dimensions “incentive/benefit”, “feasibility”, “legality”, “morality”, “likelihood of penalty” and “level of penalty” of every vignette has been determined. Additionally, we will collect data on different person factors (i.e. psychopathy, sensation seeking, self-control, sexual arousal) and investigate whether the individual weights of the appraisal dimensions vary as a function of different person factors.
Evaluating current practices in measuring and modeling adolescent alcohol frequency data

description: Substance use is a significant health risk behavior from both developmental and public health perspectives. In recent years, there has been substantial growth in the theoretical conceptualization of pathways to substance use during adolescence. However, in order to test these developmental theories researchers must be able to validly measure and model substance use. This project evaluated the current standard practices in measuring and modeling adolescent alcohol frequency data. Using a simulation study and empirical demonstration, I investigated the degree to which the quantitative characteristics of ordinal measures and ordinal scoring approaches impact researchers' ability to draw valid inferences from standard linear models. My results showed that ordinal alcohol frequency measures interacted with scoring approaches to substantially reduce statistical power and led to different patterns of effects. There was no clearly superior ordinal scoring approach and, in some conditions, the performance of scoring approaches depended on which measure was used.

description: In this paper we consider a mathematical model for photoacoustic imaging which takes into account attenuation due to thermodynamic dissipation. The propagation of acoustic (compressional) waves is governed by a scalar wave equation coupled to the heat equation for the excess temperature. We seek to recover the initial acoustic profile from knowledge of acoustic measurements at the boundary. We recognize that this inverse problem is a special case of boundary observability for a thermoelastic system. This leads to the use of control/observability tools to prove the unique and stable recovery of the initial acoustic profile in the weak thermoelastic coupling regime. This approach is constructive, yielding a solvable equation for the unknown acoustic profile. Moreover, the solution to this reconstruction equation can be approximated numerically using the conjugate gradient method. If certain geometrical conditions for the wave speed are satisfied, this approach is well--suited for variable media and for measurements on a subset of the boundary. We also present a numerical implementation of the proposed reconstruction algorithm.

Modeling, identifying, and emulating dynamic adaptive streaming over HTTP
Creators: name: Reed, Andrew
Publisher: name: University of North Carolina at Chapel Hill
Year: 2014

description: As HTTP-based streaming video applications have grown to become a major source of Internet traffic, and as the new ISO standard Dynamic Adaptive Streaming over HTTP (DASH) gains industry acceptance, researchers need the ability to both (i) study real-world viewing data and (ii) emulate realistic DASH streams in network experiments. The first effort is complicated by the fact that researchers are often restricted to anonymized, header-only (i.e. payload-truncated) traces. The second effort is difficult since the process of encoding videos for DASH results in numerous large files and since popular videos are subject to restrictive copyright law. In this thesis we present our work towards developing a model for DASH traffic and show how the model can be applied to identify specific DASH videos in anonymized, header-only traces. We also present our solution for emulating DASH using compact representations of both DASH services (e.g. Netflix and Amazon) and videos.

description: Meson mixing is considered to be an ideal candidate for new physics searches. Current experimental precision has greatly increased over the recent years, excelling in several cases the theoretical precision. A possible limit in the theoretical accuracy could be a hypothetical breakdown of quark-hadron duality. We propose a simple model for duality violations and give stringent bounds on such effects for mixing observables, indicating regions, where future measurements of $ΔΓ_d$, $a_{sl}^d$ and $a_{sl}^s$ would be clear signals of new physics. Finally, we turn our attention to the charm sector, and reveal that already a modest duality violation of about $20 \%$ could explain the huge difference between HQE predictions for D-mixing and experimental data.

description: Rotating waves are a fascinating feature of a wide array of complex systems, particularly those arising in the study of many chemical and biological processes. With many rigorous mathematical investigations of rotating waves relying on the model exhibiting a continuous Euclidean symmetry, this work is aimed at understanding these nonlinear waves in the absence of such symmetries. Here we will consider a spatially discrete lattice dynamical system of Ginzburg-Landau type and prove the existence of rotating waves in the anti-continuum limit. This result is achieved by providing a link between the work on phase systems stemming from the study of identically coupled oscillators on finite lattices to carefully track the solutions as the size of the lattice grows. It is shown that in the infinite square lattice limit of these phase systems that a rotating wave solution exists, which can be extended to the Ginzburg-Landau system of study here. The results of this work provide a necessary first step in the investigation of rotating waves as solutions to lattice dynamical systems in an effort to understand the dynamics of such solutions outside of the idealized situation where the underlying symmetry of a differential equation can be exploited.

We specifically examined the reception conditions of vulnerable persons such as minors. Furthermore, we examined the issue of the freedom of movement of applicants during the examination of their application for international protection and the possibility of the state to deprive them of material reception conditions. An attempt was made to record the developments and what is taking place on the above issues through the case law of the European Court of Human Rights and the Court of Justice of the European Union, the acts of the institutions of the European Union and relevant practice that has evolved to date. In particular, through the case law and practices of the States we have tried to reflect the attitude of the Member States towards applicants during their reception

The solutions are based on Eshelby's stress-free, in general polynomial, eigenstrains and equivalent inclusion method. To some extent, the interactions among inclusions in a non-dilute medium are taken into account by means of the self-compatibility algorithm. Moreover, the library is furnished with a powerful I/O interface and conventional homogenization tools. Advantages and limitations of the implemented strategies are addressed through comparisons with reference solutions by means of the Finite Element Method.

description: Although Wikipedia’s immense success is partially due to its support of the asynchronous collaboration model, researchers argue that the bureaucratic rules and technical infrastructure enabling it feed into Wikipedia’s content bias. Attempts to introduce different collaboration models have so far failed, but the fact that they have occurred persistently over time suggests that at least part of the Wikipedia community favours incorporating features such as real-time collaborative editing. My research is founded on the argument that the advantageous aspects of the asynchronous model should be preserved, although the existing model needs to be complemented by real-time collaboration in settings such as Wikipedia training events. This thesis describes a Participatory Design process resulting in a prototype called WikiSync, a system that introduces real-time collaboration for the Wikipedia community using a responsible design approach that is respectful of Wikipedia’s rich social structure and history. Furthermore, my research has produced an adaptive methodology for co-designing sociotechnical solutions in a geographically distributed community. After an in-depth observation of online Wikipedia training and the existing community innovation processes, my participatory design sessions have helped create a mutual learning environment for co-designing WikiSync in tandem with the community, while addressing a wide range of their concerns about real-time collaboration. I also consulted the broader Wikipedia community using an online social ideation and voting tool to evaluate the desirability and applicability of the solution. Finally, the resulting ethnographically-informed distributed Participatory Design framework provides an innovation process for involving a diverse, widely distributed online community in co-designing sociotechnical solutions.

description: Parabolic almost conformally symplectic structures were introduced in the first part of this series of articles as a class of geometric structures which have an underlying almost conformally symplectic structure. If this underlying structure is conformally symplectic, then one obtains a PCS-structure. In the current article, we relate PCS-structures to parabolic contact structures. Starting from a parabolic contact structure with a transversal infinitesimal automorphism, we first construct a natural PCS-structure on any leaf space of the corresponding foliation. Then we develop a parabolic version of contactification to show that any PCS-structure can be locally realized (uniquely up to isomorphism) in this way. In the second part of the paper, these results are extended to an analogous correspondence between contact projective structures and so-called conformally Fedosov structures. The developments in this article provide the technical background for a construction of sequences and complexes of differential operators which are naturally associated to PCS-structures by pushing down BGG sequences on parabolic contact structures. This is the topic of the third part of this series of articles.

description: The pyrochlore insulator Yb2Ti2O7 has attracted the attention of experimentalists and theoreticians alike for about 15 years. Conflicting neutron diffraction data on the possible existence of magnetic Bragg reflections at low temperature have been published. Here we report the observation of magnetic Bragg reflections by neutron powder diffraction at 60 mK. The magnetic diffraction pattern is analyzed using representation theory. We find Yb2Ti2O7 to be a splayed ferromagnet as reported for Yb2Sn2O7, a sibling compound with also dominating ferromagnetic interactions as inferred from the positive Curie-Weiss temperature. However, the configuration of the magnetic moment components perpendicular to the easy axis is of the all-in--all-out type in Yb2Ti2O7 while it is two-in--two-out in Yb2Sn2O7. An overall experimental picture of the magnetic properties emerges.

description: We consider the orbital stability of relative equilibria of Hamiltonian dynamical systems on Banach spaces, in the presence of a multi-dimensional invariance group for the dynamics. We prove a persistence result for such relative equilibria, present a generalization of the Vakhitov-Kolokolov slope condition to this higher dimensional setting, and show how it allows to prove the local coercivity of the Lyapunov function, which in turn implies orbital stability. The method is applied to study the orbital stability of relative equilibria of nonlinear Schr{ö}dinger and Manakov equations. We provide a comparison of our approach to the one by Grillakis-Shatah-Strauss.

description: We investigate the absorption properties of graphene-based anisotropic metamaterial structures where the metamaterial layer possesses an electromagnetic response corresponding to a near-zero permittivity. We find that through analytical and numerical studies, near perfect absorption arises over an unusually broad range of beam incidence angles. Due to the presence of graphene, the absorption is tunable via a gate voltage, providing dynamic control of the energy transmission. We show that this strongly enhanced absorption arises due to a coupling between light and a fast wave-mode propagating along the graphene/metamaterial hybrid.

Παράλληλα πραγματοποιήθηκε μελέτη πρωτότυπου αρχαιοβοτανικού υλικού από θέση της Βόρειας Ελλάδας, το Αρχοντικό Γιαννιτσών. Τα αρχαιοβοτανικά κατάλοιπα προέρχονταν από στρώματα της Εποχής του Χαλκού. Τα είδη που προσδιορίστηκαν επιβεβαιώνουν τα αρχαιοβοτανικά δεδομένα, έτσι όπως έχουν διαμορφωθεί από την έρευνα, της περιοχής, ενώ ταυτόχρονα παρουσιάζουν ομοιότητες με τα δεδομένα των θέσεων της νοτιοανατολικής Ευρώπης.
description: This paper examines the archaeobotanical remains of the Late Bronze Age in Northern Greece and the Balkans. The main purpose of the work was to investigate the role of plants in the diet of the prehistoric inhabitants in the settlements of southeastern Europe. Based on the data studied, it was observed that during this time in South-Eastern Europe, socio-economic changes took place, while in relation to plant foods, new species are adopted or rejected by the respective settlements, reflecting possible new commercial networks, contacts and social identities. At the same time, a study was carried out of original archaeobotanical material from a site in Northern Greece, Arxodico. The archaeobotanical remains came from Bronze Age layers. The identified species confirm the archaeobotanical data, as they have been formed by the research, of the region, while at the same time they show similarities with the data of the sites of south-eastern Europe.

description: Αντικείμενο της παρούσας μεταπτυχιακής διπλωματικής εργασίας είναι η μελέτη της επίδρασης που έχει η προσθήκη του υπολείμματος του καφέ στο πολυ(γαλακτικό οξύ) με σκοπό τη χρήση του ως υλικό συσκευασίας. Στόχος είναι η αξιοποίηση του αποβλήτου που προκύπτει από την παρασκευή του ροφήματος του καφέ για τη δημιουργία φιλικών προς το περιβάλλον φιλμ συσκευασίας, κάνοντας χρήση βιοδιασπώμενων πολυμερών. Πιο συγκεκριμένα, δημιουργούνται φιλμ του πολυμερούς πέντε διαφορετικών συγκεντρώσεων (2.5, 5, 10, 15 και 20 wt%) του υπολείμματος καφέ και ένα φιλμ μόνο με πολυ(γαλακτικό οξύ) με τη μέθοδο χύτευσης διαλύματος. Τα φιλμ αυτά υπόκεινται σε διάφορες μετρήσεις και εξετάζονται οπτικές, φυσικοχημικές και μηχανικές ιδιότητες για να διαπιστωθεί η καταλληλότητά τους ως υλικά συσκευασίας. Η μελέτη της διασποράς του υπολείμματος γίνεται με το στερεομικροσκόπιο, ενώ η δομή και η μορφολογία των φιλμ παρατηρείται με την Ηλεκτρονική Μικροσκοπία Σάρωσης. Επιπλέον, γίνεται προσδιορισμός της σύστασής τους μέσω φασματοσκοπίας υπερύθρου, προσδιορισμός αντιοξειδωτικής ικανότητας μέσω φασματοφωτόμετρου υπεριώδους-ορατού, καθώς και μελέτη των μηχανικών ιδιοτήτων. Στις μετρήσεις αυτές προστίθενται η μελέτη της διαλυτότητας και του βαθμού διόγκωσης των φιλμ, καθώς και ιδιότητες φραγμού όπως διαπερατότητα σε υδρατμούς και αέρια, οξυγόνο και διοξείδιο του άνθρακα.
description: The aim of this research is the study of the effect of spent coffee grounds when they are added in poly(lactic acid) films and are used as packaging materials. The desirable goal is the utilization of this kind of waste, which is collected after the preparation of coffee beverage, along with biodegradable polymers in order to compose eco-friendly packaging films. Specifically, five concentrations of spent coffee grounds (2.5, 5, 10, 15, 20 wt%) are added in poly(lactic acid) via solution casting method in order to prepare films. Τhe aforementioned films along with neat PLA film undergo different measurements of their optical, physicochemical and mechanical properties for their adequacy as packaging materials. The dispersion of spent coffee grounds in PLA films is observed with stereomicroscope, while structure and morphology are studied by using Scanning Electron Microscopy. Furthermore, Infrared Spectroscopy is used for the analysis of the composition and UV-vis spectrophotometer for the antioxidant activity of the films. Mechanical properties are also studied. Properties like film solubility and swelling degree as well as barrier properties, such as water vapor permeability and gas permeability, in oxygen and carbon dioxide, are also determined.

description: The controversial profile of Vladimir Putin has been the source of interest of many researchers. This interest, though, has aggravated after the outbreak of the Russo-Ukrainian war which has caused a series of socio-political changes in the international arena. This thesis, in particular, analyzes three speeches delivered by Vladimir Putin after the outbreak of the war and detects the conceptual metaphors and metonymies used by him in order to construct scenarios that have a certain argumentative meaning. The method that was used for the detection of conceptual metaphors and metonymies was MIPVU. Furthermore, an analysis of political cartoons is included in which the conceptual metaphors and metonymies used form counter-scenarios that oppose the arguments proposed by Putin in his own speeches. The analysis provided through this thesis attempts to prove the dominant presence of cognitive tools used by Putin in order for him to achieve certain political motives. On the other hand, this thesis indicates the significance of counter-scenarios as defense mechanisms to the strategies adopted by political figures.
description: Το αμφιλεγόμενο προφίλ του Βλαντιμίρ Πούτιν έχει υπάρξει πηγή ενδιαφέροντος για πολλούς ερευνητές. Αυτό το ενδιαφέρον ωστόσο γιγαντώθηκε μετά το ξέσπασμα του Ρωσο-Ουκρανικού πολέμου, γεγονός που έχει οδηγήσει σε μία σειρά από κοινωνικο-πολιτικές αλλαγές στη διεθνή αρένα. Η συγκεκριμένη διπλωματική, αναλύει τρεις πολιτικούς λόγους που εκφώνησε ο Βλαντιμίρ Πούτιν μετά το ξέσπασμα του πολέμου και εντοπίζει τις εννοιακές μεταφορές και μετωνυμίες που χρησιμοποιήθηκαν από τον ίδιο για τη διάπλαση σεναρίων που φέρουν μία συγκεκριμένη επιχειρηματολογική σημασία. Η μέθοδος που χρησιμοποιήθηκε για τον εντοπισμό των εννοιακών μεταφορών και μετωνυμιών είναι η MIPVU. Επιπλέον, η διπλωματική περιλαμβάνει και ανάλυση πολιτικών γελοιογραφιών στις οποίες οι εννοιακές μεταφορές και μετωνυμίες χρησιμοποιήθηκαν για τη δημιουργία αντι-σεναρίων που αντιτίθενται στα επιχειρήματα που προτείνονται από τον Πούτιν στους λόγους του. Η ανάλυση αυτής της διπλωματικής προσπαθεί να αποδείξει την κυρίαρχη παρουσία των εννοιακών εργαλείων τα οποία χρησιμοποιούνται από τον Πούτιν για την επίτευξη συγκεκριμένων πολιτικών στόχων. Από την άλλη, η διπλωματική εργασία υποδυκνύει τη σημασία των αντι-σεναρίων που λειτουργούν σαν αμυντικοί μηχανισμοί απέναντι στις στρατηγικές που χρησιμοποιούνται από πολιτικές φιγούρες.

description: Let $U_ζ$ be a Lusztig quantum enveloping algebra associated to a complex semisimple Lie algebra $\mathfrak g$ and a root of unity $ζ$. When $L,L'$ are irreducible $U_ζ$-modules having regular highest weights, the dimension of $\operatorname{Ext}^n_{U_ζ}(L,L')$ can be calculated in terms of the coefficients of appropriate Kazhdan-Lusztig polynomials associated to the affine Weyl group of $U_ζ$. This paper shows for $L,L'$ irreducible modules in a singular block that $\dim\operatorname{Ext}^n_{U_ζ}(L,L')$ is explicitly determined using the coefficients of parabolic Kazhdan-Lusztig polynomials. This also computes the corresponding cohomology for $q$-Schur algebras and many generalized $q$-Schur algebras. The result depends on a certain parity vanishing property which we obtain from the Kazhdan-Lusztig correspondence and a Koszul grading of Shan-Varagnolo-Vasserot for the corresponding affine Lie algebra.

"The Accidental Virgin": An Analysis of Sex, Sexuality, and Reproductive Health in Seventeen Magazine
Creators: name: Berger-Singer, Leah
Publisher: name: Georgia State University

description:
Public debates on youth sexuality, sex education, and reproductive rights are forever changing. Social media outlets are important knowledge spaces for teens to learn, share, and seek information regarding these topics. Using feminist content analysis, I explore how eight issues of Seventeen magazine construct and uphold conservative fears of teen sexuality. With the application of Michelle Fines four discourses of female sexuality, found in public-school sex education, (sexuality as individual morality, sexuality as victimization, sexuality as violence, and the missing discourse of desire) I seek to address how Seventeen constructs its target audience as a cis-gendered, heterosexual, teen girl who lives without sexual desire or the need for medically accurate sex education or reproductive health services. With the recent overturn of Roe v. Wade, this study seeks to acknowledge how public discourses of sex, sexuality, and reproductive health directly impact how youth view their individual bodily autonomy or lack thereof.

description: Magellanic spiral galaxies are a class of one-armed systems that often exhibit an offset stellar bar, and are rarely found around massive spiral galaxies. Using a set of N-body and hydrodynamic simulations we consider a dwarf-dwarf galaxy interaction as the driving mechanism for the formation of this peculiar class of systems. We investigate here the relation between the dynamical, stellar and gaseous disk center and the bar. In all our simulations the bar center always coincides with the dynamical center, while the stellar disk becomes highly asymmetric during the encounter causing the photometric center of the Magellanic galaxy disk to become mismatched with both the bar and the dynamical center. The disk asymmetries persist for almost 2 Gyrs, the time that it takes for the disk to be re-centered with the bar, and well after the companion has passed. This explains the nature of the offset bar found in many Magellanic-type galaxies, including the Large Magellanic Cloud (LMC) and NGC 3906. In particular, these results, once applied to the LMC, suggest that the dynamical center should reside in the bar center instead of the HI center as previously assumed, pointing to a variation in the current estimate of the north component of the LMC proper motion.

description: Mechanical stress may be associated with orthodontic miniscrew loosening, contributing to failure. This study evaluated stresses from loads on miniscrews with varying angulation/material type combinations using Finite Element Analysis(FEA). Left posterior maxilla and TOMAS miniscrew models were constructed with buccal miniscrew insertion between UL5/6 at 45°,60°, and 90°angulations. Titanium(Ti), stainless steel(SS) and composite(Comp) materials were used for miniscrews. After retraction load placement models were solved with ANSYS 10.0. Maximum principle(MaxPS), minimum principle(MinPS) and von Mises(vonMS) stresses were evaluated in cortical bone and miniscrew for all angulation/material combinations. Peak ultimate tensile strengths were 1/3 below bone and miniscrew MaxPS. MaxPS in bone was greatest at 45° and least at 60°. Comp miniscrew stress trends don't follow Ti and SS with varied angulation. Varied angulation likely doesn't contribute to miniscrew failure. Stress properties of SS miniscrews compare favorably with Ti miniscrews; however, Comp shows variance which could be clinically and biologically significant.
