description: Mechanisms underlying the poor breast cancer prognosis among obese women are unresolved. DNA methylation levels are linked to obesity and to breast cancer survival. We hypothesized that obesity may work in conjunction with the epigenome to alter prognosis. Using a population-based sample of women diagnosed with first primary breast cancer, we examined modification of the obesity-mortality association by DNA methylation. In-person interviews were conducted approximately 3 months after diagnosis. Weight and height were assessed [to estimate body mass index (BMI)], and blood samples collected. Promoter methylation of 13 breast cancer-related genes was assessed in archived tumor by methylation-specific PCR and Methyl Light. Global methylation in white blood cell DNA was assessed by analysis of long interspersed elements-1 (LINE-1) and with the lumino-metric methylation assay (LUMA). Vital status among 1308 patients (with any methylation biomarker and complete BMI assessment) was determined after approximately 15 years of follow-up (N = 194/441 deaths due to breast cancer-specific/all-cause mortality). We used Cox proportional hazards regression to estimate hazard ratios (HRs) and 95 % confidence intervals (CIs) using two-sided p values of 0.05. Breast cancer-specific mortality was higher among obese (BMI ≥ 30) patients with promoter methylation in APC (HR = 2.47; 95 % CI = 1.43–4.27) and TWIST1 (HR = 4.25; 95 % CI = 1.43–12.70) in breast cancer tissue. Estimates were similar, but less pronounced, for all-cause mortality. Increased all-cause (HR =1.81; 95 % CI = 1.19–2.74) and breast cancer-specific (HR = 2.61; 95 % CI = 1.45–4.69) mortality was observed among obese patients with the lowest LUMA levels. The poor breast cancer prognosis associated with obesity may depend on methylation profiles, which warrants further investigation.

description: Type I X-ray bursts are thermonuclear flashes observed from the surfaces of accreting neutron stars (NSs) in Low Mass X-ray Binaries. Oscillations have been observed during the rise and/or decay of some of these X-ray bursts. Those seen during the rise can be well explained by a spreading hot spot model, but large amplitude oscillations in the decay phase remain mysterious because of the absence of a clear-cut source of asymmetry. To date there have not been any quantitative studies that consistently track the oscillation amplitude both during the rise and decay (cooling tail) of bursts. Here we compute the light curves and amplitudes of oscillations in X-ray burst models that realistically account for both flame spreading and subsequent cooling. We present results for several such "cooling wake" models, a "canonical" cooling model where each patch on the NS surface heats and cools identically, or with a latitude-dependent cooling timescale set by the local effective gravity, and an "asymmetric" model where parts of the star cool at significantly different rates. We show that while the canonical cooling models can generate oscillations in the tails of bursts, they cannot easily produce the highest observed modulation amplitudes. Alternatively, a simple phenomenological model with asymmetric cooling can achieve higher amplitudes consistent with the observations.

description: Practice guidelines incorporate genomic tumor profiling, using results such as the Oncotype DX Recurrence Score (RS), to refine recurrence risk estimates for the large proportion of breast cancer patients with early-stage, estrogen receptor-positive disease. We sought to understand the impact of receiving genomic recurrence risk estimates on breast cancer patients’ well-being and the impact of these patient-reported outcomes on receipt of adjuvant chemotherapy. Participants were 193 women (mean age 57) newly diagnosed with early-stage breast cancer. Women were interviewed before and 2–3 weeks after receiving the RS result between 2011 and 2015. We assessed subsequent receipt of chemotherapy from chart review. After receiving their RS, perceived pros (t = 4.27, P < .001) and cons (t = 8.54, P <.001) of chemotherapy increased from pre-test to post-test, while perceived risk of breast cancer recurrence decreased (t = 2.90, P = .004). Women with high RS tumors were more likely to receive chemotherapy than women with low RS tumors (88 vs. 5 %, OR 0.01, 0.00–0.02, P < .001). Higher distress (OR 2.19, 95 % CI 1.05–4.57, P < .05) and lower perceived cons of chemotherapy (OR 0.50, 95 % CI 0.26–0.97, P < .05) also predicted receipt of chemotherapy. Distressed patients who saw few downsides of chemotherapy received this treatment. Clinicians should consider these factors when discussing chemotherapy with breast cancer patients.

description: Black Americans disproportionately experience more negative interactions with police, in comparison to White Americans (Cooley et al., 2019). As such, Black Americans tend to be more subjected to discriminatory practices used by police such as racially-driven stop and frisk practices. One factor that may contribute to this is the perception of “suspicious” behavior that police officers perceive from Black Americans. Nervous behavior is a primary justification for police stops (DOJ, 2017). However, the “suspicious” behavior may stem from feelings of nervousness in the interaction with the police, due to the general tense relation between the two groups. The current study examines how participants’ race affects behavior around police officers, when accounting for participants' attitudes towards police (e.g., believing police are trustworthy).

description: A seguinte tese de doutorado explorou a integração das artes, como cinema, literatura, música, teatro, cordel, quadrinhos, escultura e pintura, como ferramentas de ensino no contexto da Física Moderna e Contemporânea (FMC). A pesquisa se baseou na capacidade das artes não apenas de facilitar a compreensão dos conceitos complexos da FMC, mas também de promover a fusão da ciência com a cultura, abordando a significativa carência de cultura científica na sociedade, notadamente no cenário brasileiro. A questão fundamental abordada nesta pesquisa foi como a aplicação das artes como recursos didáticos pode estreitar a relação entre a Física Moderna e Contemporânea e a cultura científica, ao mesmo tempo em que impulsiona a Alfabetização Científica. Fundamentada nas teorias do pensamento complexo de Edgar Morin, a pesquisa adotou uma abordagem quali-quantitativa abrangente. Isso incluiu uma revisão sistemática da literatura e uma análise altmétrica com foco na disseminação do conhecimento científico, com ênfase no ensino de Física, notadamente nas redes sociais. Além disso, a metodologia envolveu a execução de uma sequência didática em uma turma de graduação, explorando estratégias específicas que incorporam as artes no processo de ensino. Simultaneamente, foram realizadas investigações em visitantes e um grupo amador de Astronomia em um planetário, onde as artes aproxima-os a compreensão de conceitos da FMC. Os principais resultados da pesquisa destacaram um crescente interesse na intersecção entre a Física Contemporânea e as Artes. As artes se revelaram como ferramentas eficazes no processo de ensino-aprendizagem da FMC, motivando os estudantes, contextualizando os conteúdos e simplificando a compreensão dos conceitos científicos. Em última análise, a tese fornece evidências sólidas de que a integração das artes como recursos didáticos na perspectiva da Física Moderna e Contemporânea é uma abordagem promissora. Essa abordagem não apenas aproxima os estudantes de conceitos complexos, mas também estimula o interesse nas Ciências e, fundamentalmente, contribui para superar a escassez de cultura científica na sociedade, particularmente no contexto brasileiro. As conclusões sugerem que essa abordagem pode resultar no desenvolvimento de práticas educacionais inovadoras, formando um público mais engajado e crítico em relação à ciência e à cultura, representando, assim, um avanço significativo na Alfabetização Científica.

description: In the United States, applied behavior analysis (ABA) is broadly recognized as a medically necessary treatment for individuals diagnosed with autism and related disorders (Association of Professional Behavior Analysts, 2020). We argue that this designation should not be called into question in the light of a particular disaster and that it is critical to consider that an interruption of services can have long-lasting effects on the treatment of the individual (practitioners are ethically obligated to uphold the continuity of services while doing no harm). This dilemma might be ameliorated by a decision model that considers the prioritization of immediate needs, vulnerability of clients, and competency of service providers. Just as the medical field prioritizes immediate needs during crisis situations and defers routine appointments (e.g., physicals, check-ups, etc.), the ABA field can make similar evidence-based decisions. The purpose of the current paper is to provide a decision model for ABA practitioners who find themselves questioning the need for essential service delivery during the current Coronavirus (COVID-19) pandemic. The impact of this model goes beyond the needs of this crisis and can be applied to any emergency situation where services are at risk of interruption.

description: At the LHC, an effective theory of the Higgs sector allows us to analyze kinematic distributions in addition to inclusive rates, although there is no clear hierarchy of scales. We systematically analyze how well dimension-6 operators describe LHC observables in comparison to the full theory, and in a range where the LHC will be sensitive. The key question is how the breakdown of the dimension-6 description affects Higgs measurements during the upcoming LHC run for weakly interacting models. We cover modified Higgs sectors with a singlet and doublet extension, new top partners, and a vector triplet. First, weakly interacting models only generate small relevant subsets of dimension-6 operators. Second, the dimension-6 description tends to be justified at the LHC. Scanning over model parameters, significant discrepancies can nevertheless arise; their main source is the matching procedure in the absence of a well-defined hierarchy of scales. This purely theoretical problem should not affect future LHC analyses.

title: Propagation dynamics of two species competition models in a periodic discrete habitat
Creators: name: Fan, Shiheng
Publisher: name: Memorial University of Newfoundland
Year: 2022

description: Spreading speeds and traveling waves are essential in qualitative studying biological invasions. Sometimes, the invading species can lead to the extinction of the local species competing for resources, and such a phenomenon is called competition exclusion. In this thesis, we study the propagation dynamics of a Lotka-Volterra competition model in a periodic discrete habitat when competition exclusion occurs. First, we present general results on spreading speeds and traveling waves for monotone systems in a periodic discrete habitat. Under appropriate assumptions, we show that a semi-trivial equilibrium is globally stable for the spatially periodic initial value problem when competition exclusion happens. Then we establish the existence of the right ward spreading speed and its coincidence with the minimal wave speed for the spatially periodic right ward traveling waves. We obtain sufficient conditions for the linear determinacy of the right ward spreading speed. Ultimately, we apply all these results to a specific model and conduct numerical simulations to investigate the spreading of the two competing species in a periodic habitat.

description: Two classical hypotheses are examined about the population growth in a system of cities: Hypothesis 1 pertains to Gibrat's and Zipf's theory which states that the city growth-decay process is size independent; Hypothesis 2 pertains to the so called Yule process which states that the growth of populations in cities happens when (i) the distribution of the city population initial size obeys a log-normal function, (ii) the growth of the settlements follows a stochastic process. The basis for the test is some official data on Bulgarian cities at various times. This system was chosen because (i) Bulgaria is a country for which one does not expect biased theoretical conditions; (ii) the city populations were determined rather precisely. The present results show that: (i) the population size growth of the Bulgarian cities is size dependent, whence Hypothesis 1 is not confirmed for Bulgaria; (ii) the population size growth of Bulgarian cities can be described by a double Pareto log-normal distribution, whence Hypothesis 2 is valid for the Bulgarian city system. It is expected that this fine study brings some information and light on other, usually considered to be more pertinent, city systems in various countries.

description: The chiral anomaly-induced negative magnetoresistance and non-trivial Berry phase are two fundamental transport properties associated with the topological properties of Weyl fermions. In this work, we report the quantum transport of TaP single crystals in magnetic field up to 31T. Through the analyses of our magnetotransport data, we show TaP has the signatures of a Weyl state, including light effective quasiparticle masses, ultrahigh carrier mobility, as well as negative longitudinal magnetoresistance. Furthermore, we have generalized the Lifshitz-Kosevich formula for Shubnikov-de Haas (SdH) oscillations with multi-frequencies, and determined the non-trivial Berry phase of Pi for multiple Fermi pockets in TaP through the direct fitting of the quantum oscillations. In high fields, we also probed signatures of Zeeman splitting, from which the Landé g-factor is extracted.

description: Monetary incentive delay (MID) tasks are a popular task for examining the time course of reward processing, with the majority of research having been conducted using fMRI. In the past 3-5 years, there has been an explosion of interest in using the MID to examine rapid patterns of neural activity at different stages of reward processing, links between stages, and the potential for this activity to be a biomarker or endophenotype for psychopathology. However, much of the research in this area is still quite preliminary, and the parameters of components (and factors which predict variation) are unknown, but necessary if the measures are to have any validity. In this meta-analysis, we examine the consistency of ERP modulation in the MID task, and examine potential factors that contribute to heterogeneity in ERP modulation.

Conformal Barrier and Hidden Local Symmetry Constraints: Walking Technirhos in LHC Diboson Channels

description: We expand the previous analyses of the conformal barrier on the walking technirho for the 2 TeV diboson excesses reported by the ATLAS collaboration, with a special emphasis on the hidden local symmetry (HLS) constraints. We first show that the Standard Model (SM) Higgs Lagrangian is equivalent to the scale-invariant nonlinear chiral Lagrangian, which is further gauge equivalent to the scale-invariant HLS model, with the scale symmetry realized nonlinearly via SM Higgs as a (pseudo-) dilaton. The scale symmetry forbids the new vector boson decay to the 125 GeV Higgs plus W/Z boson, in sharp contrast to the conventional "equivalence theorem" which is invalidated by the conformality. The HLS forbids mixing between the iso-triplet technirho's, rho_{Pi} and rho_{P}, of the one-family walking technicolor (with four doublets N_D=N_F/2=4), which, without the HLS, would be generated when switching on the standard model gauging. We also present updated analyses of the walking technrho's for the diboson excesses by fully incorporating the constraints from the conformal barrier and the HLS as well as possible higher order effects: still characteristic of the one-family walking technirho is its smallness of the decay width, roughly of order Gamma/M_rho ~ [3/N_C x 1/N_D] x [Gamma/M_rho]_{QCD} ~ 70 GeV/2TeV (N_D= N_C=4), in perfect agreement with the expected diboson resonance with Gamma<100 GeV. The model is so sharply distinguishable from other massive spin 1 models without the conformality and HLS that it is clearly testable at the LHC Run II. If the 2 TeV boson decay to WH/ZH is not observed in the ongoing Run II, then the conformality is operative on the 125 GeV Higgs, strongly suggesting that the 2 TeV excess events are responsible for the walking technirhos and the 125 GeV Higgs is the technidilaton.

description: Ένας από τους βασικούς στόχους όλων των εγκληματιών στον κυβερνοχώρο είναι να δημιουργήσουν κακόβουλα προγράμματα που μπορούν να αποφύγουν τους μηχανισμούς ασφαλείας των Windows συστημάτων. Το πιο βασικό εργαλείο που χρησιμοποιούν τα συστήματα αυτά για να το αποτρέψουν είναι το Windows Defender. Πρόκειται για ένα σύστημα ασφαλείας που βρίσκεται προεγκαταστημένο στους υπολογιστές και δεν απαιτεί καμία χρέωση. Προσφέρει προστασία σε πραγματικό χρόνο κάνοντας συνεχώς σαρώσεις για κάθε νέο πρόγραμμα που εισέρχεται στο μηχάνημα αλλά και έναν μηχανισμό firewall που μπορεί να επιτρέψει στον χρήστη να καθορίσει πλήρως ποιες κινήσεις επιτρέπονται να εισέρθουν και να εξέρθουν από το δίκτυο του. Παρόλο που τα τελευταία χρόνια έχει παρατηρηθεί σαφής βελτίωση του η παράκαμψη του είναι κάτι που μπορεί να γίνει πολύ εύκολα. Η κρυπτογραφία, η αποφυγή του sandboxing, η στεγανογραφία και οι εγχύσεις DLL και κακόβουλου κώδικα σε διεργασίες είναι μερικές από τις τεχνικές που χρησιμοποιούνται με σκοπό κάποια προγράμματα να περάσουν απαρατήρητα από το Windows Defender. Για την υλοποίηση αυτών των τεχνικών υπάρχει μια πληθώρα εργαλείων ανοικτού κώδικα που ο καθένας μπορεί πολύ εύκολα να επιλέξει και κάποια από αυτά σε συνδυασμό με αυτοσχέδια κομμάτια κώδικα θα χρησιμοποιηθούν και στην παρούσα εργασία με σκοπό να ελεγχθεί η αποτελεσματικότητα του Defender. Χρησιμοποιώντας εργαλεία όπως το Anubis, το Mythic, το Africana-framework και το hoaxshell θα δοκιμαστούν ένα ransomware, ένας keylogger αλλά και προγράμματα που έχουν ως στόχο την αρχική πρόσβαση στο αντίπαλο μηχάνημα. Καταλήγοντας, θα παρατηρήσουμε ότι πολλές από τις προσπάθειες που θα δοκιμαστούν θα στεφθούν με επιτυχία παρακάμπτοντας το Windows Defender.

description: Previous studies demonstrated poor response to neoadjuvant systemic therapy (NST) for breast cancer among black women and women who are overweight or obese but this may be due to chemotherapy under dosing. We assessed associations of race, ethnicity and body mass index (BMI) with pathologic complete response (pCR) in clinical trial populations.
title: Extended symmetry analysis of (1+2)-dimensional Fokker-Planck equation
Creators: name: Koval, Serhii
Publisher: name: Memorial University of Newfoundland

description: We carry out the extended symmetry analysis of an ultraparabolic degenerate Fokker-Planck equation with three independent variables, which is also called the Kolmogorov equation and is singled out within the class of such Fokker-Planck equations by its remarkable symmetry properties. In particular, its essential Lie invariance algebra is eight-dimensional, which is the maximum dimension within the above class. We compute the complete and essential point symmetry groups of the Kolmogorov equation using the direct method and analyze their structure. After listing inequivalent one- and two-dimensional subalgebras of the essential Lie invariance algebra of this equation, we exhaustively classify its Lie reductions. As a result, we construct wide families of exact solutions of the Kolmogorov equation, and three of them are parameterized by single arbitrary solutions of the (1+1)-dimensional linear heat equation. We also establish the point similarity of the Kolmogorov equation to the (1+2)-dimensional Kramers equations whose essential Lie invariance algebras are eight-dimensional, which allows us to find wide families of exact solutions of these Kramers equations in an easy way.

description: Τα άτομα με προβλήματα όρασης αντιμετωπίζουν μοναδικές προκλήσεις στην καθημερινή τους ζωή, ιδιαίτερα όταν πρόκειται για ανεξάρτητη μετακίνηση και κατανόηση του περιβάλλοντός τους. Μια εφαρμογή Android που έχει σχεδιαστεί για να μεταφέρει ηχητικά πληροφορίες σχετικά με τα αντικείμενα που εντοπίζονται στις φωτογραφίες που τραβήχτηκαν από την κάμερα του τηλεφώνου μπορεί να βελτιώσει σημαντικά την αυτονομία αυτών των χρηστών, γι’ αυτό το λόγο δημιουργήθηκε η εφαρμογή SoundPath. Αυτή η τεχνολογία τους δίνει τη δυνατότητα να αναγνωρίζουν και να κατανοούν το περιβάλλον τους αξιοποιώντας τις δυνατότητες των smartphone τους. Μεταφράζοντας οπτικές πληροφορίες σε ηχητικές ενδείξεις, η εφαρμογή γεφυρώνει το χάσμα μεταξύ του οπτικού κόσμου και του χρήστη, προσφέροντας πληροφορίες για το περιβάλλον τους και προωθώντας μια πιο περιεκτική και προσβάσιμη εμπειρία. Αυτή η καινοτομία όχι μόνο προάγει την αίσθηση ανεξαρτησίας για τα άτομα αυτά, αλλά καταδεικνύει επίσης τις δυνατότητες της τεχνολογίας να καταρρίπτει τα εμπόδια και να δημιουργήσει ένα ψηφιακό τοπίο χωρίς αποκλεισμούς.

description: This paper presents a computational procedure for extracting demography data, mining patterns of human preferences, and measuring the topology of a virtual network. The network was created from the personal and relationships data of an online Internet-based community, where persons are considered nodes in the network, and relationships between persons are considered edges. A community of Friendster users whose listed hometown is Los Baños, Laguna was used as a test bed for the methodology. The method was able to provide the following demographic, preferential, and topological results about the test bed: (1) There are more female users (52.34\%) than male (47.66\%); (2) Homophily (i.e., birds-of-a-feather adage) is observed in the preferences of users with respect to age levels, such that they are strongly biased towards being friends with users of a similar age; (3) There is heterophily in gender preference such that friendship among users of the opposite gender occurs more often. (4) It exhibits a small-world characteristic with an average path length of 4.5 (maximum=12) among connected users, shorter than the well-known {\em six degrees of separation}~\cite{travers69}; And (5) The network exhibits a scale-free characteristics with heavily-tailed power-law distribution (with the power $λ= -1.02$ and $R^2 = 0.84$) suggesting the presence of many users acting as the network hubs. The methodology was successful in providing important data from a virtual community which can be used by several researchers in the fields of statistics, mathematics, physics, social sciences, and computer science.
