description: In this paper we calculate the entanglement entropy of two coupled gapless systems in general spatial dimension d. The gapless systems can be either conformal field theories (CFT), or Fermi liquids. We assume the two systems are coupled uniformly in a h-dimensional submanifold of the space, with 0 <= h <= d. We will focus on the scaling of the entanglement entropy with the size of the system, and its scaling with the inter-system coupling constant g. Three approaches will be used for our calculation: (1) exact calculation with ground state wave-functional, (2) perturbative calculation with functional path integral, (3) scaling argument.

description: Haematomantispa sp. Figure 6 A–E Diagnosis. This specimen has the body predominantly dark-red, pronotum longer than broad, with setae covering its entire length, wings hyaline and foreleg with 2 pretarsal claws. Examined material. Brazil, Tocantins, Palmas, Fazenda Encantada, 10°15 ʹ 0 2.6 ʺ S, 048°07 ʹ 23.1 ʺ W, 9–10.xi. 2012, Krolow, T.K. & Lima, H.I.L. leg. (1♀ CEUFT). Distribution. The genus occurs from Costa Rica to Brazil: Amazonas and Rondônia (Machado and Martins 2018). New records. Tocantins: Palmas municipality. Comments. Until now the only species of Haematomantispa known from Brazil is H. amazonica Machado & Rafael, 2010. The unique specimen studied here is a female and probably is a new species, as it does not present the main morphological characters of H. amazonica. We opted not to formally describe this new species because our specimen is a female; the male genitalia provide the most important characters to distinguish species of Haematomantispa. We made many attempts to collected more specimens but all were unsuccessful.

description: We present results from a Partial-Wave Analysis (PWA) of diffractive dissociation of 190 GeV/c $π^-$ into $π^-π^+π^-$ final states on nuclear targets. A PWA of the data sample taken during a COMPASS pilot run in 2004 on a Pb target showed a significant spin-exotic $J^{PC} = 1^{-+}$ resonance consistent with the controversial $π_1(1600)$, which is considered to be a candidate for a non-$q\bar{q}$ mesonic state. In 2008 COMPASS collected a large diffractive $π^-π^+π^-$ data sample using a hydrogen target. A first comparison with the 2004 data shows a strong target dependence of the production strength of states with spin projections $M = 0$ and 1.

Examining the effects of oxygen tension on extravillous trophoblast column outgrowth during the first trimester of pregnancy
Creators: name: Treissman, Jenna Elizabeth
Publisher: name: University of British Columbia
Year: 2019

description: Oxygen tension is thought to regulate many of the cellular and molecular processes that contribute to placenta development. An area of recent focus has been on the importance of a low-oxygen environment in controlling progenitor trophoblast differentiation along the invasive extravillous pathway. However, previously published research on the role of oxygen in trophoblast differentiation is conflicting. In this thesis, the effects of low (1%), physiologically normal (5%) and high (20%) oxygen conditions on extravillous trophoblast differentiation and column formation are examined using a human placental explant model. I show that culture in low oxygen conditions enhances column outgrowth and promotes the expression of pro-extravillous genes and gene pathways. By contrast, culture in high oxygen conditions promotes trophoblast proliferation, reduces column outgrowth and stalls differentiation along the extravillous pathway. I show that both low and physiologically normal oxygen conditions increase expression of the lysyl oxidase gene, and that this gene plays an important role in promoting extravillous column outgrowth. Together, these findings support hypoxia as an important factor driving trophoblast differentiation along the extravillous pathway. Additionally, this work provides new insight into specific molecular processes, regulated by oxygen tension, that may play an important role in early placentation.
Podcasts als linguistischer Untersuchungsgegenstand. Interaktion, Struktur, Potenzial

description: Podcasts stellen als hybrides Medium (Chadwick 2017; Arnold/Donges 2018) eine vielfältiges und komplexes Untersuchungsgebiet dar. Sie sind ein populäres und vielseitiges wie reichweitenstarkes Medium. Produktions- und Rezeptionsschwellen sinken – eine zuverlässige digitale Infrastruktur vorausgesetzt – immer weiter ab. Diese Charakteristika machen Podcasts zu einem vielversprechenden Untersuchungsgegenstand für verschiedene wissenschaftliche Disziplinen wie die Medienwissenschaften (Katzenberger/Keil/Wild 2022), Erziehungswissenschaften (Schmidt 2014), Politikwissenschaften (Lührmann 2019) und den Journalismus (Eins 2022), die sich bereits intensiv mit der Produktion und Rezeption dieses Formats auseinandergesetzt haben. Auch in der linguistischen Forschung wird das Podcast-Format zunehmend als relevantes Analyseobjekt anerkannt (Spinelli/Dann 2019; McCracken 2017). Im deutschsprachigen Raum hingegen steht die linguistische Erforschung von Podcasts noch am Anfang (Stanoeva et al. 2022; Michael 2022; Leander 2020).Der Vortrag wendet sich dem Medium Podcast als potenziellem Untersuchungsgegenstand für sprachwissenschaftliche Fragen zu. Der Fokus liegt dabei (1) zunächst bei den inhaltlichen Ausrichtungen des Mediums. Deutschsprachige Podcasts sind vielfältig – von Nachrichten, Reportagen, Interviews, politischen Inhalten bis zu Comedyformaten, Selbsthilfe und Beziehungsratgebern ist zu jedem Thema etwas zu finden. Das zeugt von einer hohen Flexibilität des Mediums. Die Produzent:innen und ihre (2) Rolle als Podcasthosts stehen im Mittelpunkt des zweiten Vortragsschwerpunkts. Das rein auditive Format – enriched Podcasts klammere ich aus – erfordert Kompetenzen im Storytelling (Dowling/Miller 2019), die über den Erfolg von Podcasts entscheiden können. Rezipient:innen heben (3) immer wieder die besondere Intimität hervor, die das Format mit sich bringt (Euritt 2023). Diese besondere Beziehung zwischen Hörer:in und Produzent:in soll in einem dritten Schwerpunkt beleuchtet werden. Obwohl es sich um ein publizistisches Medium handelt, welches öffentlich und meist auch frei verfügbar ist, wird Nähe und ein Gefühl für von Vertrautheit bis zur Privatheit (Baldauf-Quilliatre 2024) zwischen Sender:in und Hörer:in hergestellt. Diese ‘neue Nähe’ bietet neue Zugänge für Untersuchungen (Dürscheid 2016; Schneider 2016; Spitzmüller/Pfadenhauer 2024). Der Ausblick ist besonders orientiert auf das Potential von Podcasts für medien- und gesprächslinguistische Untersuchungen.

description: This work is devoted to the trade relations of Germany and the countries of Northern Europe, as well as an analysis of the process of the formation of trade in designated countries. The paper examines the emergence of statehood in both Germany and the countries of Northern Europe, and outlines the main aspects of the emergence of the trade process itself. The peculiarities of the trade interaction between Germany and Northern Europe are determined using the content analysis of studies in which the above-mentioned countries are present. On the basis of the information received, a conclusion is drawn on the main trade trends formed between Germany and Northern Europe at the beginning of the 20th century.

description: In this moment of ongoing COVID-19, intensifying racial injustice, and deepening economic inequalities, it is more imperative than ever for an honors education to play a role in helping students see their research and learning as contributing to the common good. The strength of many honors programs is their orientation toward the liberal arts, and the deep history of this emphasis in fact places the honors academic experience in a unique position to investigate the vast changes facing our world. Therefore, as faculty and staff working closely with students in honors educational settings, we need to continuously reflect on how the purpose of an honors education needs to adapt in order to inspire our students to understand and engage seriously with today’s most pressing issues.
SUPPLY CHAIN MODELING FOR OIL COMPANIES: IN THE CASE OF LIBYA OIL ETHIOPIA LIMITED
Creators: name: FIREW ABERA
Publisher: name: Zenodo
Year: 2017

description: The purpose of this paper was to highlight the oil supply chain performance in fulfilling its customers need, analyze the essential characteristics of sustainable SCM in the oil company, identify the main challenges and opportunities of oil supply chain in the oil company, develop strategies to improve forecasting problems and delivery performance of the Ethiopian oil supply chain performance and to develop an integrated oil supply chain model from the depot to the end customer. No research has been conducted regarding oil supply chain simulation in Ethiopia.

A Discrete-Event Simulation model of SCM is constructed using Arena software to implement the four-target scenarios. This study focuses on filling the gaps and develops a four-echelon supply chain model with the help of Arena simulation software to investigate and improve the Ethiopian oil industry supply chain performance with a special focus on the downstream suppliers of oil.

This paper analyses the oil supply chain operations and proposes four supply chain scenarios. Four scenarios on the inventory replenishment strategy for the oil industries are developed. After running the trials, a significant method to control the inventory level of the oil while keeping the operating performance in a reasonable level is achieved. The outputs are also analyzed to share inventory stock information and help assigned SC managers to make decisions based on facts rather than assumptions in uncertain environment. The simulation results show the optimal supply chain strategy that demonstrates the best economic performance in the oil industry.
POD/DEIM Reduced-Order Modeling of Time-Fractional Partial Differential Equations with Applications in Parameter Identification

description: In this paper, a reduced-order model (ROM) based on the proper orthogonal decomposition and the discrete empirical interpolation method is proposed for efficiently simulating time-fractional partial differential equations (TFPDEs). Both linear and nonlinear equations are considered. We demonstrate the effectiveness of the ROM by several numerical examples, in which the ROM achieves the same accuracy of the full-order model (FOM) over a long-term simulation while greatly reducing the computational cost. The proposed ROM is then regarded as a surrogate of FOM and is applied to an inverse problem for identifying the order of the time-fractional derivative of the TFPDE model. Based on the Levenberg--Marquardt regularization iterative method with the Armijo rule, we develop a ROM-based algorithm for solving the inverse problem. For cases in which the observation data is either uncontaminated or contaminated by random noise, the proposed approach is able to achieve accurate parameter estimation efficiently.

description: We explore model-independent collider constraints on light Majorana dark matter particles. We find that colliders provide a complementary probe of WIMPs to direct detection, and give the strongest current constraints on light DM particles. Collider experiments can access interactions not probed by direct detection searches, and outperform direct detection experiments by about an order of magnitude for certain operators in a large part of parameter space. For operators which are suppresssed at low momentum transfer, collider searches have already placed constraints on such operators limiting their use as an explanation for DAMA.

description: We approach the problem of linear network coding for multicast networks from different perspectives. We introduce the notion of the coding points of a network, which are edges of the network where messages combine and coding occurs. We give an integer linear program that leads to choices of paths through the network that minimize the number of coding points. We introduce the code graph of a network, a simplified directed graph that maintains the information essential to understanding the coding properties of the network. One of the main problems in network coding is to understand when the capacity of a multicast network is achieved with linear network coding over a finite field of size q. We explain how this problem can be interpreted in terms of rational points on certain algebraic varieties.

description: We study reversible polymerization of rings. In this stochastic process, two monomers bond and as a consequence, two disjoint rings may merge into a compound ring, or, a single ring may split into two fragment rings. This aggregation-fragmentation process exhibits a percolation transition with a finite-ring phase in which all rings have microscopic length and a giant-ring phase where macroscopic rings account for a finite fraction of the entire mass. Interestingly, while the total mass of the giant rings is a deterministic quantity, their total number and their sizes are stochastic quantities. The size distribution of the macroscopic rings is universal, although the span of this distribution increases with time. Moreover, the average number of giant rings scales logarithmically with system size. We introduce a card-shuffling algorithm for efficient simulation of the ring formation process, and present numerical verification of the theoretical predictions.

description: Abstract

A wide range of PFAS residues were studied in an aquifer used for drinking water production which was affected by historical PFAS contamination from a landfill and military camp. Samples were taken at three monitoring and four pumping wells at different depths ranging from 33 to 147 m below the land surface and analysed for a series of 53 PFAS (C2-C14) and PFAS precursors (C4-C24). A comparison of results to earlier research from 2013, with a more limited range of PFAS, showed decreasing concentrations and migration of PFAS with increasing depth and distance from the contamination source.

The PFAS profile and branched/linear isomer ratio are used as source characterization tools. The landfill was confirmed to contaminate the groundwater in both monitoring wells, while the military camp was indicated as a probable source for PFAS observed in the deep sampling points of one of the monitoring wells. Pumping wells used to produce drinking water are not yet affected by these two PFAS sources. In one of the four sampled pumping wells, a different PFAS profile and isomer pattern was observed, which indicated a different but yet unknown source.

This work shows the necessity of implementing regular screening to identify potential (historical) PFAS sources to be able to prevent future contaminant migration nearby and towards drinking water abstraction wells.

An exploratory analysis of parental factors related to physical activity in children living with autism
Creators: name: McFee, Erin Marie
Publisher: name: University of British Columbia
Year: 2019

description: Children with Autism Spectrum Disorder (ASD) experience unique developmental and social challenges that place them at increased risk for injury, which can present barriers to participation in physical activities that are normally a routine part of childhood. These barriers leave children with ASD at risk of obesity, and increased amounts of sedentary activities; as well as decreased levels of physical activity and community recreation participation. For parents raising children living with ASD, finding safe and developmentally appropriate activities for their children to engage in, can be a significant source of stress. This thesis presents a quantitative exploratory analysis of data collected from parents (N=69) through the Autism and Developmental Disorders Lab (ADDL) at Simon Fraser University in 2017. Using statistical methods, this research increases understanding of factors related to parents’ decisions in providing opportunities for physical activity whilst balancing risk and safety by investigating the differences/similarities that exist between parents raising a child living with ASD, and those parents who are raising a child without ASD. Specifically this analysis explored how a child’s ASD diagnosis, and/or ASD symptoms impacts parent perceived barriers to activity, child sedentary behavior/screen time, child physical activity (outside play and activity type), parents’ perceptions of protection from injury and risk; as well as the impact on parent self-efficacy in balancing their child’s protection from injury and risk. Results indicated that parents raising a child living with ASD did not differ significantly in their perceptions of protection from injury and risk, or in their self-efficacy from parents raising a child without ASD. However, parents report that their child living with ASD was exceeding recommended daily amounts of sedentary behavior/screen time. In addition, parents raising a child living with ASD were found to experience significantly more barriers to activity participation; and were limited in the types of recreational activities that were available for their children to participate in.

description: We propose a simple, yet highly efficient and robust device for producing valley polarized current in graphene. The device comprises of two distinct components; a region of uniform uniaxial strain, adjacent to an out-of-plane magnetic barrier configuration formed by patterned ferromagnetic gates. We show that when the amount of strain, magnetic field strength, and Fermi level are properly tuned, the output current can be made to consist of only a single valley contribution. Perfect valley filtering is achievable within experimentally accessible parameters.

Publisher: name: Alberta Journal of Educational Research
Year: 2014

description: This study investigated the impact of the critical inquiry model through peer feedback strategies in an online environment on university students’ critical thinking skills and examined their attitudes towards learning through the critical inquiry model and peer feedback strategies. Pre- and post-tests were employed to measure critical thinking skills based on Bloom’s questioning cognitive levels, together with a rubric designed to assess significant abilities involved in critical thinking in a domain-explicit manner. A questionnaire was used to investigate students’ attitudes. The findings reported an increase in the post-test mean scores, showing that the application of the critical inquiry model and peer feedback strategy can promote critical thinking skills. Results from the questionnaire suggested that students who used the critical inquiry model to provide peer feedback had favorable attitudes toward learning, higher levels of motivation, and increased levels of confidence when using discussions with peers in an online forum. Cette étude a examiné, d’un part, l’impact du modèle de recherche critique par les stratégies qu’emploient des étudiants à l’université pour la rétroaction des pairs en ligne et, d’autre part, les attitudes de ceux-ci relatives à l’apprentissage par le modèle de recherche critique et la rétroaction des pairs. Une analyse des pré- et post-tests et une rubrique conçue pour évaluer, en fonction de certains domaines, des habiletés significatives impliquées dans la pensée critique ont servi dans l’évaluation des aptitudes de réflexion critique selon les niveaux d’aptitudes cognitives de Bloom. Les attitudes des étudiants ont été recueillies par un questionnaire. Les résultats révèlent une augmentation dans le score moyen au post-test, indiquant ainsi que l’application du modèle de recherche critique et les stratégies de rétroaction des pairs peuvent développer la pensée critique. Selon les réponses au questionnaire, les étudiants s’étant servi du modèle de réflexion critique pour offrir de la rétroaction à leurs pairs avaient des attitudes favorables face à l’apprentissage, un niveau de motivation plus élevé et plus de confiance lors des discussions avec les pairs dans un forum en ligne.

description: We compute the low energy decay rates of near-extremal three(four) charge black holes in five(four) dimensional N=4 string theory to sub-leading order in the large charge approximation. This involves studying stringy corrections to scattering amplitudes of a scalar field off a black hole. We adapt and use recently developed techniques to compute such amplitudes as near-horizon quantities. We then compare this with the corresponding calculation in the microscopic configuration carrying the same charges as the black hole. We find perfect agreement between the microscopic and macroscopic calculations; in the cases we study, the zero energy limit of the scattering cross section is equal to four times the Wald entropy of the black hole.

Research Mediation in Education: A Typology of Research Brokering Organizations That Exist Across Canada
Creators: name: Cooper, Amanda Mae
Publisher: name: Alberta Journal of Educational Research
Year: 2014

description: This paper explores the increasingly prominent role of research brokering organizations (RBOs) in strengthening connections between education research, policy and practice across Canada. This paper is organized in three sections. First, it provides a literature review of research mediation– exploring terminology, models and empirical work (albeit sparse) across health, business, education sectors. The second section provides three conceptual contributions to the field: RBOs’ roles in knowledge mobilization occurring in the white space of broader public service systems, a typology of Canadian RBOs that exist in education using four broad categories: governmental, not-for-profit, for-profit and membership RBOs, and a knowledge brokering framework along seven dimensions: mission, resources, staff roles, political affiliation, autonomy, message and linkages. The third section provides empirical data about the frequency and types of RBOs that exist across Canada. Cet article explore le rôle de plus en plus important que jouent les organismes de médiation de la recherche dans la consolidation des liens entre les politiques et la pratique en matière de recherche en éducation partout au Canada. L’article se divise en trois sections. D’abord, on y présente une revue de la littérature portant sur la médiation de la recherche et évoquant la terminologie, les modèles et le travail empirique (quoique limités) qui touchent les secteurs de la santé, des affaires et de l’éducation. La deuxième section contribue trois concepts au domaine : les rôles que jouent les organismes de médiation de la recherche dans la mobilisation des connaissances dans les « espaces vides » de la fonction publique en général; une typologie des organismes canadiens de médiation de la recherche en éducation selon quatre grandes catégories (gouvernemental, sans but lucratif, à but lucratif et composé de membres) et un cadre portant sur la médiation de la recherche et axé sur sept dimensions (mission, ressources, rôles du personnel, affiliation politique, autonomie, messages et liens). La troisième section offre des données empiriques sur la fréquence et les types d’organismes de médiation de la recherche qui existent au Canada.

Initial teacher education for social justice and teaching work in urban schools: An (im)pertinent reflection
Creators: name: Pereira, Fátima
Publisher: name: Alberta Journal of Educational Research
Year: 2014

description: This paper presents conceptions and reflections on initial teacher education for social justice based on a study that sought to identify the discourses produced in the initial education of teachers of the first and second cycles of basic education on the concept of social justice and to understand the effects of those discourses on the educational practices of teachers beginning their careers in urban schools. The study was developed in Portugal and was based on an analysis of programs offered in the curriculum for the bachelor’s degree in elementary education and the master’s degree in teaching of the first cycle of basic education (CEB) (first four years of schooling) and the second CEB (fifth and sixth school grades) and on biographical interviews with teachers of the first and second CEB who trained in the last five years and a teacher educator. The results show the inadequacy of initial teacher education in relation to the educational mandates that some of the urban schools apply to teachers’ work and that the ideology of inclusion characterizes the discourses analysed. The results also reveal that the ethical dimension of the profession is not yet seen as integrating the core curriculum, being more dependent on human sensitivity, on teachers’ initial education and on educators’ professional ideology. Cet article présente des conceptions et des réflexions sur la formation initiale des enseignants pour la justice sociale à partir d’une étude visant à identifier les discours produits lors de cette formation. Nous avons examiné les premier et deuxième cycles de la formation de base portant sur le concept de la justice sociale pour comprendre les effets de ces discours sur les pratiques pédagogiques des enseignants qui débutent leur carrière dans des écoles en milieu urbain. Développée au Portugal, l’étude est basée, d’une part, sur une analyse des programmes offerts dans le cadre du baccalauréat en éducation au primaire et de la maitrise en éducation du premier cycle (quatre premières années de scolarité) et du deuxième cycle (5e et 6e années) et, d’autre part, sur des entrevues biographiques auprès d’enseignants formés dans les cinq dernières années et auprès d’un formateur. Les résultats démontrent l’insuffisance de la formation initiale des enseignants par rapport aux mandats éducatifs de certaines écoles en milieu urbain. L’analyse des discours révèle que l’idéologie de l’inclusion les caractérise. Finalement, les conclusions indiquent également que l’intégration du curriculum de base n’est toujours pas accomplie dans l’éthique de la profession, celle-ci s’appuyant davantage sur la sensibilité humaine, la formation initiale des enseignants et l’idéologie professionnelle des enseignants.

description: This study presents a comprehensive comparative analysis of the various manuscripts and printed editions of Alisher Navoi’s Hayrat ul-Abror, exploring the linguistic, textual, and philosophical variations that have emerged across different regions and historical periods. By employing a multidisciplinary methodology that combines philological analysis with historical-contextual examination, the research identifies significant lexical, syntactic, and thematic differences in the text. These variations are closely tied to the cultural and intellectual environments in which the manuscripts were produced, particularly the influence of Sufi metaphysics and regional linguistic norms. The findings underscore the dynamic nature of manuscript transmission and highlight how Navoi’s work was continually reshaped by evolving intellectual and cultural trends. The study contributes to a deeper understanding of literary transmission in the Persianate world and offers new insights into the broader processes of textual adaptation and interpretation.

description: A theoretical study of the polarization entanglement of two photons emitted in the decay of metastable ionic states is performed within the framework of density matrix theory and second-order perturbative approach. Particular attention is paid to relativistic and non-dipole effects that become important for medium- and high-$Z$ ions. To analyze these effects, the degree of entanglement is evaluated both in the dipole approximation and within the rigorous relativistic theory. Detailed calculations are performed for the two-photon $2s_{1/2}\to 1s_{1/2}$ transition in hydrogen-like, as well as for the $1s_{1/2}\, 2s_{1/2} \; {}^1S_0 \to 1s_{1/2}^2 \; {}^1S_0$, $1s_{1/2} \, 2s_{1/2} \; {}^3S_1\to 1s_{1/2}^2 \; {}^1S_0$ and $1s_{1/2} \, 2p_{1/2} \; {}^3P_0\to 1s_{1/2}^2 \; {}^1S_0$ transitions in helium-like ions.

description: Представлены результаты оптимизации топологии магнитной компоненты трехслойной магнитоэлектрической (МЭ) композиционной структуры с целью повышения чувствительности к магнитному полю активных МЭ приборов на основе магнитострикционных-пьезополупроводниковых структур. В качестве магнитных слоев использовался аморфный ферромагнетик — метглас АМАГ 225 в виде пластины размером 28×8 мм, двух полос размером 28×4 мм, четырех полос размером 28×2 мм и восьми полос размером 28×1 мм. Исследование МЭ эффекта проводилось в частотном диапазоне от 1 до 150 кГц и внешнем постоянном магнитном поле H0 величиной от 0 до 50 Э. C увеличением числа полос до восьми и уменьшением ширины каждой из них до 1 мм наблюдалось увеличение величины МЭ коэффициента по напряжению αE более чем в 2 раза по сравнению со значением, полученным для исходной пластины размером 28×8 мм.

description: Aims: We seek to illustrate the analysis problems posed by RHESSI spacecraft motion by studying persistent instrumental oscillations found in the lightcurves measured by RHESSI's X-ray detectors in the 6-12 keV and 12-25 keV energy range during the decay phase of the flares of 2004 November 4 and 6. Methods: The various motions of the RHESSI spacecraft which may contribute to the manifestation of oscillations are studied. The response of each detector in turn is also investigated. Results: We find that on 2004 November 6 the observed oscillations correspond to the nutation period of the RHESSI instrument. These oscillations are also of greatest amplitude for detector 5, while in the lightcurves of many other detectors the oscillations are small or undetectable. We also find that the variation in detector pointing is much larger during this flare than the counterexample of 2004 November 4. Conclusions: Sufficiently large nutation motions of the RHESSI spacecraft lead to clearly observable oscillations in count rates, posing a significant hazard for data analysis. This issue is particularly problematic for detector 5 due to its design characteristics. Dynamic correction of the RHESSI counts, accounting for the livetime, data gaps, and the transmission of the bi-grid collimator of each detector, is required to overcome this issue. These corrections should be applied to all future oscillation studies.
