description: One of the most important parameters defining the angular resolution of an X-ray optical module is its Half-Energy Width (HEW) as a function of the photon energy. Future X-ray telescopes with imaging capabilities (SIMBOL-X, Constellation-X, NeXT, EDGE, XEUS,...) should be characterized by a very good angular resolution in soft (< 10 keV) and hard (> 10 keV) X-rays. As a consequence, an important point in the optics development for these telescopes is the simulation of the achievable HEW for a system of X-ray mirrors. This parameter depends on the single mirror profile and nesting accuracy, but also on the mirrors surface microroughness that causes X-ray Scattering (XRS). In particular, owing to its dependence on the photon energy, XRS can dominate the profile errors in hard X-rays: thus, its impact has to be accurately evaluated in every single case, in order to formulate surface finishing requirements for X-ray mirrors. In this work we provide with some simulations of the XRS term of the HEW for some future soft and hard X-ray telescopes.

description: In this paper we introduce a new type of Pascal's pyramids. The new object is called hyperbolic Pascal pyramid since the mathematical background goes back to the regular cube mosaic (cubic honeycomb) in the hyperbolic space. The definition of the hyperbolic Pascal pyramid is a natural generalization of the definition of hyperbolic Pascal triangle and Pascal's arithmetic pyramid. We describe the growing of hyperbolic Pascal pyramid considering the numbers and the values of the elements. Further figures illustrate the stepping from a level to the next one.

Meta-Science and Open Science for Ecology: The Revolution We Need
Creators: name: Culina, Antica
Publisher: name: Zenodo
Year: 2023

description: Ecological research is crucial to solving both local and global issues. For this to be successful and timely, the relevant information must be accurate and unbiased, and the flow of information (such as data or analytical approaches) among research groups improved. However, there are several barriers that, coupled with generally high heterogeneity of ecological systems, hinder the transition towards a more open research landscape. These barriers can broadly be divided into current research culture/practices (e.g. not sharing data, evaluation based on published papers) and technical barriers (e.g. lack of standards, infrastructures).

 In my talk, I will showcase some general and some particular challenges that ecology faces in the open science transition. I will then highlight some solutions, based on mine and others work, to overcome these challenges, where I will particularly focus on the importance of open and FAIR data, computational reproducibility, and preregistration of (observational) studies. I will further discuss why ecology is uniquely positioned to benefit from open science and meta-research, given the diversity of study systems and biological heterogeneity present in these systems. I will emphasize the importance of meta-research in guiding the development adoption of open science solutions in ecology, hoping more researchers in ecology will engage in meta-research. The talk will conclude with a discussion on the best ways to get researchers on board with open science practices, and some ideas on how to achieve a better support system, research evaluation, and publishing.

description: We report experimental and numerical results on the buildup of the energy spectrum in wave turbulence of a vibrating thin elastic plate. Three steps are observed: first a short linear stage, then the turbulent spectrum is constructed by the propagation of a front in wave number space and finally a long time saturation due to the action of dissipation. The propagation of a front at the second step is compatible with scaling predictions from the Weak Turbulence Theory.

Mechanisms for convection triggering by cold pools

description: Cold pools are fundamental ingredients of deep convection. They contribute to organizing the sub-cloud layer and are considered key elements in triggering convective cells. It was long known that this could happen mechanically, through lifting by the cold pools' fronts. More recently, it has been suggested that convection could also be triggered thermodynamically, by accumulation of moisture around the edges of cold pools. A method based on Lagrangian tracking is here proposed to disentangle the signatures of both forcings and quantify their importance in a given environment. Results from a simulation of radiative-convective equilibrium over the ocean show that parcels reach their level of free convection through a combination of both forcings, each being dominant at different stages of the ascent. Mechanical forcing is an important player in lifting parcels from the surface, whereas thermodynamic forcing reduces the inhibition encountered by parcels before they reach their level of free convection.

The role of tau in Alzheimer’s Disease: Effects of Lys-280 and Lys-281 acetylation on tau function and structure
Creators: name: Constance, Brian
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: The tau protein is implicated in Alzheimer’s disease (AD), and it is a prominent feature of AD pathology. In AD, tau's normal ability to stabilize microtubules (MTs) is impaired, and tau becomes aggregated. Aberrant post-translational modifications (PTMs) of tau may provide an explanation for why this occurs. There are mounting indications that tau acetylation plays a role in AD, with acetylated K280 being discovered as a marker of tau aggregation in AD brain. We hypothesize that acetylation of lysines in tau’s microtubule binding region (MTBR) causes a loss of tau stabilizing function and a gain of propensity to form aggregates. Using lysine to glutamine (K->Q) mutations to model acetylation, we provide evidence suggesting that single (K280) or double (K280/K281) acetylation inhibits MT assembly. Furthermore, we implicate the K280 acetylation in accelerating tau aggregation, and in the seeding of aberrantly phosphorylated, tau aggregation.

description: Around 2% of all A stars have photospheres depleted in refractory elements. This is hypothesized to arise from a preferential accretion of gas rather than dust, but the specific processes and the origin of the material -- circum- or interstellar -- are not known. The same depletion is seen in 30% of young, disk-hosting Herbig Ae/Be stars. We investigate whether the chemical peculiarity originates in a circumstellar disk. Using a sample of systems for which both the stellar abundances and the protoplanetary disk structure are known, we find that stars hosting warm, flaring group I disks typically have Fe, Mg and Si depletions of 0.5 dex compared to the solar-like abundances of stars hosting cold, flat group II disks. The volatile, C and O, abundances in both sets are identical. Group I disks are generally transitional, having radial cavities depleted in millimetre-sized dust grains, while those of group II are usually not. Thus we propose that the depletion of heavy elements emerges as Jupiter-like planets block the accretion of part of the dust, while gas continues to flow towards the central star. We calculate gas to dust ratios for the accreted material and find values consistent with models of disk clearing by planets. Our results suggest that giant planets of ~0.1 to 10 M_Jup are hiding in at least 30% of Herbig Ae/Be disks.

description: We study the algbraic dynamics for endomorphisms of projective spaces with coefficients in a p-adic field whose reduction in positive characteritic is the Frobenius. In particular, we prove a version of the dynamical Manin-Mumford conjecture and the dynamical Mordell-Lang conjecture for the coherent backward orbits for such endomorphisms. We also give a new proof of a dynamical version of the Tate-Voloch conjecture in this case. Our method is based on the theory of perfectoid spaces introduced by P. Scholze. In the appendix, we prove that under some technical condition on the field of definition, a dynamical system for a polarized lift of Frobenius on a projective variety can be embedding into a dynamical system for some endomorphism of a projective space.

Exploring Distorted Thinking About Food and Dietary Misinformation in Nonclinical Samples: Instrument and Intervention Development and Validation

Nonclinical sample

description: Distorted thinking about food is common in both clinical and nonclinical populations from dieters to diabetics and eating disorder patients. This type of thinking is triggered by exposure to dieting culture (including related social media), familial dieting, and internalization of the thin ideal, among other factors. The consequences of distorted thinking about food include disordered eating, weight management problems, body dissatisfaction and many others. Despite these findings, distorted thinking about food in nonclinical samples remains poorly understood. Thus, the current research sought to investigate distorted thinking about food within a broad theoretical model that includes societal antecedents important to understanding the nature of this construct in the general population. This model, which is based on Cognitive Behaviour Therapy (CBT) and the Theory of Planned Behaviour (TPB; Ajzen, 1991), was investigated in two studies. The first study is a psychometric validation study of a tool designed to measure distorted thinking about food, the Calorie Catastrophizing Scale (CCS; Monaghan & Santor, 2017) as well as the tool designed to measure dietary misinformation, the Dietary Misinformation Questionnaire (DMQ; Monaghan & Santor, 2017). Results lend support for defining and measuring distorted thinking about food as a distinct construct in nonclinical individuals and suggest that dietary misinformation is an important antecedent to this type of thinking and unhealthy eating behaviours. The second study is a randomized controlled trial of a CBT- and TPB-based workshop intervention aimed at reducing these antecedents. Results show that this intervention led to a significant reduction in distorted thinking about food, dietary misinformation, and other important clinical variables such as symptoms of eating pathology. These findings have a number of important implications for how subclinical eating problems are conceptualized, measured, and prevented.

description: Background: The undersupply of health professionals in rural areas impacts healthcare access for those living in rural Australia. A strategy to increase the rural health workforce is to recruit and educate rural people. However, long-standing inequities for rural Australians in accessing tertiary education persist. The aim of this study was to audit the 2023 offerings of Australian allied health, nursing, dental and medical university courses to identify geographical availability and those delivered online. Methods: A desktop audit of Australian allied health, nursing, dental and medical courses offered in 2023 was undertaken to identify the courses and delivery modes of those courses offered in regional, rural and remote locations. The audit involved searching lists of professionally accredited courses and university websites, which is publicly available information about health courses. Data were tabulated and descriptive statistics used for data analysis. Results: There were marked differences in online and rural course offerings across health professions in Modified Monash (MM) Model category 2–7 locations. Nursing/midwifery had the most courses while pharmacy, podiatry, dental and medicine had few offerings and optometry had none. Social work, nursing/midwifery and psychology also had the most online course offerings. Most courses were offered in MM2 and MM3 locations with few offerings in rural or remote areas. The availability of studying part-time was very limited and often this was only for the early years of the course. Inconsistencies relating to the course information on university websites existed relating to course delivery mode descriptions. Conclusions: There is a lack of rural on-campus or online course offerings for some allied health disciplines, dentistry and medicine. Provision of end-to-end, flexible courses in rural areas or online is needed to reduce access barriers for rural students and to enable sustainable rural health workforce development.

description: We present a study on the crystallization process of undoped and Ta doped TiO2 amorphous thin films. In particular, the effect of ultra-fast annealing treatments in environments characterized by different oxygen concentrations is investigated via in-situ resistance measurements. The accurate examination of the key parameters involved in this process allows us to reduce the time needed to obtain highly conducting and transparent polycrystalline thin films (resistivity about $6 \times 10^{-4}$ Ωcm, mean transmittance in the visible range about $81\%$) to just 5 minutes (with respect to the 180 minutes required for a standard vacuum annealing treatment) in nitrogen atmosphere (20 ppm oxygen concentration) at ambient pressure. Experimental evidence of superficial oxygen incorporation in the thin films and its detrimental role for the conductivity are obtained by employing different concentrations of traceable 18O isotopes during ultra-fast annealing treatments. The results are discussed in view of the possible implementation of the ultra-fast annealing process for TiO2-based transparent conducting oxides as well as electron selective layers in solar cell devices; taking advantage of the high control of the ultra-fast crystallization processes which has been achieved, these two functional layers are shown to be obtainable from the crystallization of a single homogeneous thin film.

description: The Community Multiscale Air Quality (CMAQ) model instrumented with the Direct Decoupled Method in three dimensions (DDM-3D), an advanced method for sensitivity analysis of chemical transport models, is used to quantify individual impacts of large and mid-size US airports on ambient air quality. Sensitivity coefficients are generated for six precursor species groups, allowing estimations of ozone and PM2.5 concentrations from each of 66 individual airports. Airports were divided into groups, minimizing interference and allowing more airports to be analyzed while keeping total simulation runtimes as low as possible. Chorded aviation activity data from the Aviation Environmental Design Tool (AEDT) were used to generate speciated emissions along flight tracks during landing and takeoff (LTO) activities. Sensitivity grids were generated for ozone and primary and secondary components of fine particulate matter for the 66 airports in the domain. Emissions from these airports account for 61% of flights and 77% of fuel burn in the 2005 AEDT inventory; sensitivities from these airports account for 73% of total aviation LTO PM2.5 sensitivities and 57% of total aviation LTO ozone sensitivities in the domain. Aircraft LTO operations for all airports in the domain were found to be responsible for an increase in annual average PM2.5 concentrations of 2.4E-3 ug/m3 nationwide (0.038% of PM2.5 concentrations from all sources), with this level climbing to as high as 0.025 ug/m3 near major airports. Ozone concentrations displayed an annual domain average 8-hr max sensitivity of 1.8E-2 ppbv (0.036% of ozone concentrations from all sources). Sensitivity to PM2.5 precursor emissions from individual airports was often far-reaching. Thirteen airports produced total PM2.5 sensitivities in excess of 1E-3 ug/m3 at 250km, and 52 airports produced sensitivities in excess of 1E-4 ug/m3 at the same distance; sensitivities at these distances tend to be primarily composed of secondary species, while sensitivities closer to airports are balanced more evenly between primary and secondary species. Spatially-resolved estimation of PM2.5 from NAS-wide aircraft LTO operations was calculated to be responsible for an excess all-cause mortality of 131 (95% CI: 121--142) deaths per year. These individual airport sensitivities will be used in the future to generate further estimates of current health and economic impacts of aviation activity, and to inform policy decisions regarding growth and operations in the aviation sector.
Teaching Open Science in Media Studies

Publisher: name: Zenodo
Year: 2023

description: At the Institute for Media Studies in Marburg, the seminar “Open Science and Media Studies” was held in the winter semester 2022/23 to test how Open Science can be integrated into media studies teaching. On the one hand, this is a challenge in terms of content for the students, who have so far been trained more in analyses of individual media (e.g. film), and on the other hand, it places a stronger focus on (digital) methods, praxeological considerations, and theories of science and media. The seminar sessions not only dealt with Open Access, Open Data, Open Educational Resources, Open Methodology, Open Peer Review, Open Source or Citizen Science, but also with how media studies as a humanities discipline with its professional needs fits into the entire Open Science movement or what openness actually means for media studies. Within the didactic setting, it was particularly important not only to teach openness thematically, but also to actively live it when teaching. This means using Etherpads or Zenodo groups for collaborative work and actively involving students in the design of seminar sessions such as topic selection.

 The talk wants to present the didactic approach as well as its implementation and reflect the results of the course. Based on this, the lessons learned will be presented. Furthermore, the lecture would like to make a plea for not leaving the libraries or graduate schools alone with teaching offers for Open Science, but to show that Open Science is an essential aspect of disciplinary teaching.
Procedural reaction time and balance performance during a dual or single task in healthy collegiate students
Creators: name: Ross, Luke Michael
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2008

description: Recent evidence has revealed deficiencies in the ability to split attention following concussive injury. The current concussion assessment paradigm used by sports medicine clinicians fails to grasp the interaction between balance and cognition necessary to participate in sport. Few studies have examined splitting attention in our current concussion assessment paradigm. The purpose of our study was to examine the effects of a dual task paradigm on procedural reaction time and balance in healthy subjects. To do this, subjects performed a series of balance and PRT tasks under the single task and dual task conditions during two test sessions performed exactly 14 days apart. While obtaining few significant findings, there appears to be a role for both the BESS and the SOT for utilization in a dual task methodology. Future research should examine the effect of a dual task for assessment and tracking recovery following concussive injury.

Is touch gating due to sensory or cognitive interference? An investigation using repeated testing
Creators: name: Harper, Daniel Elliott
Publisher: name: University of North Carolina at Chapel Hill
Year: 2011

description: The present study was conducted to determine whether touch gating, in which pain decreases tactile sensitivity, is the result of sensory or cognitive interference. Touch gating was repeatedly produced by delivering a co-localized painful heat stimulus (45 C) during measurements of vibration threshold on the palm. Pain significantly increased thresholds compared to those measured at normal skin temperature and this interference did not decline over the course of the experiments, despite the fact that perceived pain significantly habituated. For comparison, Stroop interference was also measured repeatedly; this cognitive interference declined significantly across sessions and bore no resemblance to touch gating interference. Touch gating was not correlated with measures of distractibility, fear of pain, hypervigilance, or anxiety - variables previously found to contribute to pain's ability to cause cognitive interference. Taken together, the results suggest that touch gating is a sensory phenomenon, one that cannot be explained by pain's capability to distract.
Corruption in Healthcare: Analyzing the Impact of Governance on Medical Corruption in the United States and Germany
Creators: name: Leahy, Megan Elise
Publisher: name: University of North Carolina at Chapel Hill
Year: 2013

description: This thesis contributes to the literature on corruption in healthcare systems by comparing the effectiveness of governance in two wealthy, stable democracies: the United States and Germany. Supported by evidence from an assessment of four dimensions of governance in healthcare systems, including accountability, transparency, monitoring and regulation and trust, it is argued that systems with less regulatory control and intervention from the state are more susceptible to higher rates of corruption. Implications from this research and evaluation may aid public officials around the world in designing more effective modes of healthcare governance, and eventually improving the overall access to and quality of healthcare provision.

description: In cognitive neuroscience, an emerging research area concerns experience-induced changes in brain structure and function, referred to as neural plasticity. Neuroimaging studies have demonstrated that programmes to train core cognitive processes including executive functions can drive changes on neural measures in healthy adults (Klingberg, 2010; Hsu et al., 2014). However, most researchers to date have employed functional brain imaging procedures, with working memory training regimes being the most popular and extensively examined so far. On the contrary, training related changes in the brain’s structure have rarely been examined (Pappa et al., 2020). This project will examine grey matter (GM) changes after training the process of working memory updating (WMU) in a group of young healthy adults.

description: The relation between galaxies and dark matter halos reflects the combined effects of many distinct physical processes. Observations indicate that the $z=0$ stellar mass-halo mass (SMHM) relation has remarkably small scatter in stellar mass at fixed halo mass ($\lesssim$ 0.2 dex) with little dependence on halo mass. We investigate the origins of this scatter by combining N-body simulations with observational constraints on the SMHM relation. We find that at the group and cluster scale ($M_{\rm vir}>10^{14}{M_\odot}$) the scatter due purely to hierarchical assembly is $\approx0.16$ dex, which is comparable to recent direct observational estimates. At lower masses, mass buildup since $z\approx2$ is driven largely by in-situ growth. We include a model for the in-situ buildup of stellar mass and find that an intrinsic scatter in this growth channel of $0.2$ dex produces a relation between scatter and halo mass that is consistent with observations from $10^{12}{M_\odot}

Conflict, Cooperation, and Congressional End-Runs: The Defense Budget and Civil-Military Relations in the Carter Administration, 1977-1978
Creators: name: Mini, John D.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2007

description: President Jimmy Carter became commander-in-chief at an important juncture in American civil-military relations. This study adds to the largely neglected historiography of civil-military relations during the Carter years by examining the administration’s first two years, using the civil-military dialogue surrounding the fiscal year 1978 and fiscal year 1979 defense budgets as its primary category of analysis. The study demonstrates that growing cooperation within the Pentagon, increasing conflict between the Pentagon and the White House, and a strengthening military-congressional alliance best characterized civil-military relations in the first two years of the Carter administration. This pattern of civil-military relations prevailed primarily due to early and intense presidential involvement in the defense budgetary process and because of the administration’s attempts to re-prioritize defense spending. The culmination of this pattern of civil-military relations in the administration’s first two years was the presidential veto of the fiscal year 1979 defense appropriations bill.

The longstanding view that shear thickening is due to hydrodynamic clusters has been challenged by recent theory and simulations suggesting that contact forces dominate, not only in discontinuous, but also in continuous shear thickening. Here, we settle this dispute using shear reversal experiments on micron-sized silica and latex colloidal particles to measure directly the hydrodynamic and contact force contributions to shear thickening. We find that contact forces dominate even continuous shear thickening. Computer simulations show that these forces most likely arise from frictional interactions.

description: The Open Science movement continues to advance global research access. Around the world, researchers are gaining access to previously unavailable articles, software and data through Open Science infrastructures, FAIR data standards and access policies.

 Despite these advances, Open Science infrastructures require constant scrutiny to ensure equity of access. More scrutiny is needed to examine access by marginalized research communities and address structural challenges to data use and reuse. Without this scrutiny, it is possible that existing socio-economic inequalities are unintentionally being perpetuated within the new Open Science milieu. Failure to address these inequities weakens Open Science and undermines the ideal of a Global Digital Commons.

 In this talk I present some recent work looking at unequal access to Open Science resources due to socio-economic and geographical realities. The research challenges the implicit assumption within both FAIR and Open discussions that access to Open Science resources are independent of the user’s geolocation. Many researchers continue to struggle to access Open Science resources due to connectivity issues or explicit geoblocking. These challenges undermine the equity of Open Science resources, as well as limiting marginalized researchers from from Open Science discussions and adapting Open Science infrastructures to improve equity of access.

 These marginalisations mirror wider political issues and infrastructural deficits, and raises serious questions about the limits of openness. Without targeted action, and given the volatile nature of politics and the slow pace of infrastructural investment, the expansion of Open Science may unintentionally reinforce current access inequities and research inequalities around the globe.

description: Objective: To evaluate the influence of hip strength on kinematic ACL injury risk factors and gluteal activation. Design: Cross-sectional. Setting: Research laboratory. Participants: Eighty-two healthy volunteers. Outcome Measures: Hip extension, external rotation, and abduction strength; gluteus maximus and medius electromyography (EMG); knee valgus, hip adduction, and hip internal rotation angles. Results: Peak knee valgus (p=0.016) and hip external rotation (p=0.023) angles were greater in individuals with weaker hip external rotators. Gluteus maximus EMG was greater in individuals with weaker hip extensors (p=0.031) and external rotators (p=0.043). Hip external rotation strength and gluteus maximus EMG amplitude predicted 7.9% and 12.1% of the variance in peak hip rotation (R= 0.281, p=0.039.) and knee valgus angles (R=0.348, p=0.006). Conclusion: Hip external rotation strength influences hip and knee kinematics related to ACL injury, thus increasing gluteal strength may be an important addition to ACL injury prevention programs. Key Words: ACL, strength, EMG, knee valgus

description: Open science policies have been implemented worldwide, but there is a research gap in understanding how these policies affect researchers' knowledge production practices. In order to better understand how open science is incorporated into mode 2 of knowledge production in the basic sciences of physics, chemistry, and biology in Brazil, France, and Peru, this paper uses a qualitative research methodology. Researchers at the top institutions in each nation are asked for their ideas, perceptions, and experiences with the policies through semi-directed interviews. The interview transcriptions were analyzed using Nvivo software. The coding process employed a thematic analysis with an inductive category development approach. The research question is focused on understanding how open science policies have impacted knowledge production practices of researchers in these countries, highlighting differences and similarities across science disciplines. By addressing the existing research gap, it enhances the empirical literature on open science and adds diversity to the understanding of this subject.
Design and Validation of a Microfluidic Device for Controlled Cell Stimulation

description: Understanding how cells receive chemical signals from their surrounding environment and transform them into appropriate responses is a fundamental problem in biology. A significant challenge in studying this signal processing is controlling the cellular input signals with sufficient precision such that mathematical frameworks, e.g. control theory, can be more readily applied to their modeling and analysis. To address this problem, we have developed and experimentally validated a microfluidic device that can deliver chemical treatments in discrete packets, or plugs, to cells with high spatiotemporal precision. Using monolithic valves, we can insert a chemical plug in the channel and flow it past the cells. Taylor dispersion morphs the initial well-defined plug into a Gaussian curve. Application of the device was demonstrated by exposing human epidermal keratinocytes, skin cells, to plugs of ethanol and examining cell viability versus exposure time. Results suggest that this device can be used for controlled cell stimulation.

description: Le distorsioni di caviglia acute (Lateral Ankle Sprain, LAS) e/o le condizioni di instabilità cronica di caviglia (Chronic ANkle Instability, CAI) possono favorire lo sviluppo di debolezza a carico della muscolatura dell'anca? La ricerca scientifica ha affermato che la debolezza muscolare di anca rappresenta un fattore di rischio per l'insorgenza di distorsioni di caviglia, ma non ha ancora dimostrato il contrario: se ciò fosse vero, si determinerebbe un circolo vizioso di influenza reciproca tra articolazione di caviglia e di anca, con un impatto epidemiologico, economico e sociale importante che andrebbe a interferire negativamente sulla qualità della vita. Per rispondere a questa domanda, valuteremo tramite dinamometro manuale la forza isometrica della muscolatura dell'anca in seguito a una o più distorsioni di caviglia, tramite uno studio osservazionale eziologico caso-controllo e di coorte con coorte concorrente, che includerà 140 soggetti suddivisi in 5 gruppi: gruppo controllo, gruppi LAS e CAI retrospettivi, gruppi LAS e CAI prospettici. La prima misurazione di forza isometrica dell'anca, sarà seguita da altre 3 misurazioni (follow up a 3, 6, 12 mesi dalla prima misurazione), per valutare e monitorare l'influenza delle distorsioni di caviglia a carico della muscolatura dell'anca in un arco di tempo di 12 mesi. Confermando la nostra ipotesi, potremmo dare un importante contributo all'attuale intervento riabilitativo nella gestione delle distorsioni di caviglia acute e delle instabilità croniche di caviglia.

description: We present a detailed study of the classical Cepheid in the double-lined, highly eccentric eclipsing binary system OGLE-LMC562.05.9009. The Cepheid is a fundamental mode pulsator with a period of 2.988 days. The orbital period of the system is 1550 days. Using spectroscopic data from three 4-8-m telescopes and photometry spanning 22 years, we were able to derive the dynamical masses and radii of both stars with exquisite accuracy. Both stars in the system are very similar in mass, radius and color, but the companion is a stable, non-pulsating star. The Cepheid is slightly more massive and bigger (M_1 = 3.70 +/- 0.03M_sun, R_1 = 28.6 +/- 0.2R_sun) than its companion (M_2 = 3.60 +/- 0.03M_sun, R_2 = 26.6 +/- 0.2R_sun). Within the observational uncertainties both stars have the same effective temperature of 6030 +/- 150K. Evolutionary tracks place both stars inside the classical Cepheid instability strip, but it is likely that future improved temperature estimates will move the stable giant companion just beyond the red edge of the instability strip. Within current observational and theoretical uncertainties, both stars fit on a 205 Myr isochrone arguing for their common age. From our model, we determine a value of the projection factor of p = 1.37 +/- 0.07 for the Cepheid in the OGLE-LMC562.05.9009 system. This is the second Cepheid for which we could measure its p-factor with high precision directly from the analysis of an eclipsing binary system, which represents an important contribution towards a better calibration of Baade-Wesselink methods of distance determination for Cepheids.
