description: In the context of the TraMoS project we present nine new transit observations of the exoplanet OGLE-TR-113b observed with the Gemini South, Magellan Baade, Danish-1.54m and SOAR telescopes. We perform a homogeneous analysis of these new transits together with ten literature transits to probe into the potential detection of an orbital decay for this planet reported by \citet{adams2010}. Our new observations extend the transit monitoring baseline for this system by 6 years, to a total of more than 13 years. With our timing analysis we obtained a $\dot{P}=-1.0 \pm 6.0$ ms~yr$^{-1}$, which rejects previous hints of a larger orbital decay for OGLE-TR-113b. With our updated value of $\dot{P}$ we can discard tidal quality factors of $Q_{\star} < 10^{5}$ for its host star. Additionally, we calculate a 1$σ$ dispersion of the Transit Timing Variations (TTVs) of 42 seconds over the 13 years baseline, which discards additional planets in the system more massive than $0.5-3.0~M_{\oplus}$ in 1:2, 5:3, 2:1 and 3:1 Mean Motion Resonances with OGLE-TR-113b. Finally, with the joint analysis of the 19 light curves we update transit parameters, such as the relative semi-major axis $a / R_s = 6.44^{+0.04}_{-0.05}$, the planet-to-star radius ratio $R_p / R_s =0.14436^{+0.00096}_{-0.00088}$, and constrains its orbital inclination to $i =89.27^{+0.51}_{-0.68}$~degrees.

Improving Recruitment of African American Males to Prostate Screenings

description: African American men have the highest rate of prostate cancer. Further, African American men are more likely to be diagnosed with prostate cancer in a more advanced stage of the disease and are more likely to die of it than any other racial or ethnic group in the US. Although prostate screening is controversial, data suggests that for the African American population early detection may help eliminate or reduce the disparity between racial groups. Poor African American participation at prostate cancer screening events is a significant barrier to early detection. Several approaches to recruiting African Americans have been documented in the literature including the lay health educator model and education within a faith based setting. This paper reviews current issues surrounding health disparities related to prostate cancer; issues related to prostate cancer screening; the concept of lay health advisors; and education in the African American church as an avenue to recruit African Americans to prostate cancer screenings. Craven County's unique experience in increasing African American participation in a local prostate cancer screening program over a recent three-year period will be presented. Successes and failures of the program and other lessons learned in using concepts from the lay health advisor model within the African American churches to educate and recruit participants for the screening will be discussed.

description: For propulsive applications, it is important to understand the expansion of a supersonic ion beam in a magnetic nozzle as it is one of the main thrust generation mechanisms in electrode-less radio-frequency plasma thrusters. The present study discusses the effects of magnetic field strength on the axial characteristics of an ion beam. Experiments are conducted in a radio-frequency magnetic nozzle plasma device at The University of Auckland with four different magnetic field strengths configurations. A four-grid retarding field energy analyser is used to measure the local plasma and ion beam potentials, the axial evolution of the ion energy distribution functions, and to estimate the ion beam density and speed. While greater ion beam speeds are measured at the lower magnetic field strengths ( ~ 10 km/s compared to ~ 9 km/s for the highest field case), the ion beam current collected at the maximum magnetic nozzle strength is found to be nine times higher than that for the minimum field case. This behaviour is evidenced by the rise in amplitude of the ion beam energy distribution measured for higher magnetic field strengths. The axial transport of the ion beam is also observed to be modified by the magnetic nozzle strength. As the magnitude of B increases, the presence of an ion beam is detected over longer axial distances.

description: Proposta de Extração de Energia do Vácuo Quântico Baseada na Teoria Menezes: Manipulação de Qubits e Geometria Fracionária do Espaço-Tempo

Nesta proposta, introduzimos uma abordagem inovadora para a extração de energia do vácuo quântico, fundamentada na Teoria Menezes, que postula que o espaço-tempo é uma manifestação emergente de uma rede de qubits entrelaçados e superpostos. A manipulação controlada dessa rede de qubits permite não apenas a amplificação das flutuações quânticas do vácuo, mas também a concentração da energia de ponto zero em regiões específicas do espaço-tempo. Explora-se a possibilidade de utilizar modos solitônicos para o transporte dessa energia, bem como o uso da geometria fracionária do espaço-tempo para otimizar a captura de energia. Discutimos os fundamentos teóricos, a viabilidade experimental e as implicações tecnológicas dessa proposta, oferecendo um novo paradigma para a exploração de fontes de energia quânticas.

Embora a proposta ofereça novas perspectivas teóricas, reconhecemos que ela enfrenta desafios significativos tanto em termos de viabilidade experimental quanto tecnológica. Esta linha de pesquisa deve ser vista como uma exploração de longo prazo com o potencial de abrir novas fronteiras na física quântica e na geração de energia.

A exploração de energia do vácuo quântico, especificamente da energia de ponto zero (ZPE), tem sido um campo de intensa especulação e investigação na física teórica. A energia de ponto zero representa a energia residual presente em um sistema quântico mesmo em seu estado fundamental. Na teoria de campos quânticos, o vácuo quântico não é um vazio absoluto, mas um estado de constante flutuação de campos quânticos, que dão origem à criação e aniquilação de partículas virtuais. Essas flutuações indicam que o vácuo possui uma densidade de energia não nula, que, em princípio, poderia ser explorada.

A Teoria Menezes oferece uma nova perspectiva ao postular que o espaço-tempo e suas propriedades emergem de uma rede fundamental de qubits entrelaçados. Esse modelo fornece uma estrutura na qual a energia de ponto zero pode ser entendida como uma manifestação das interações quânticas subjacentes. Nesta proposta, exploramos como a manipulação dessa rede de qubits pode permitir a extração de energia do vácuo quântico, oferecendo um caminho inovador e potencialmente viável para a exploração de novas fontes de energia.

description: We study the dynamics of polymer chains in a bath of self-propelled particles (SPP) by extensive Langevin dynamics simulations in a two dimensional system. Specifically, we analyse the polymer looping properties versus the SPP activity and investigate how the presence of the active particles alters the chain conformational statistics. We find that SPPs tend to extend flexible polymer chains while they rather compactify stiffer semiflexible polymers, in agreement with previous results. Here we show that larger activities of SPPs yield a higher effective temperature of the bath and thus facilitate looping kinetics of a passive polymer chain. We explicitly compute the looping probability and looping time in a wide range of the model parameters. We also analyse the motion of a monomeric tracer particle and the polymer's centre of mass in the presence of the active particles in terms of the time averaged mean squared displacement, revealing a giant diffusivity enhancement for the polymer chain via SPP pooling. Our results are applicable to rationalising the dimensions and looping kinetics of biopolymers at constantly fluctuating and often actively driven conditions inside biological cells or suspensions of active colloidal particles or bacteria cells.

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2008

description: In October 2007 the state of Tennessee began enforcement of a workplace smoking ban now known as the “Non-Smoker Protection Act”. In an effort to help local health departments be well positioned to assist individuals with smoking cessation the Department of Health rolled out a patient assessment and treatment program. For best results, this program can take an epidemiological approach. Epidemiology is defined as the study of the distribution of determinants and antecedents of health and disease in human populations, with the goal of identifying their underlying causes and ultimately the application of findings for disease prevention and health promotion (Turnock 387). By understanding some key characteristics of the patients our providers encounter, such as socioeconomic status and nicotine dependence, we can develop cost effective strategies to achieve optimum success with the smoking cessation program.
Dicke's Superradiance in Astrophysics. II -- The OH 1612 MHz Line

description: We apply the concept of superradiance introduced by Dicke in 1954 to the OH molecule 1612 MHz spectral line often used for the detection of masers in circumstellar envelopes of evolved stars. As the detection of 1612 MHz OH masers in the outer shells of envelopes of these stars implies the existence of a population inversion and a high level of velocity coherence, and that these are two necessary requirements for superradiance, we investigate whether superradiance can also happen in these regions. Superradiance is characterized by high intensity, spatially compact, burst-like features taking place over time-scales on the order of seconds to years, depending on the size and physical conditions present in the regions harboring such sources of radiation. Our analysis suggests that superradiance provides a valid explanation for previous observations of intensity flares detected in that spectral line for the U Orionis Mira star and the IRAS18276-1431 pre-planetary nebula.

The Italian Space Agency (AS!) plans to allocate a slot on a commercial lunar lander to showcase an in-situ resource utilization (ISRU) process. Multiple architectures have been proposed to demonstrate the process while fulfilling the lander\'s requirements. These architectures are based on an analysis of plant functionalities, with a focus on key components. Thermal analysis highlights power as a critical resource with potential solutions to maintain the required reaction temperature. The challenges of miniaturization for fluidics are also addressed.

description: We have developed an analytical model based on the perturbation theory in order to study the optical propagation of two successive intense solitons in hollow-core photonic crystal fibers filled with Raman-active gases. Based on the time delay between the two solitons, we have found that the trailing soliton dynamics can experience unusual nonlinear phenomena such as spectral and temporal soliton oscillations and transport towards the leading soliton. The overall dynamics can lead to a spatiotemporal modulation of the refractive index with a uniform temporal period and a uniform or chirped spatial period.

description: High-contrast imaging provided by a coronagraph is critical for the direction imaging of the Earth-like planet orbiting its bright parent star. A major limitation for such direct imaging is the speckle noise that is induced from the wave-front error of an optical system. We derive an algorithm for the wave-front measurement directly from 3 focal plane images. The 3 images are achieved through a deformable mirror to provide specific phases for the optics system. We introduce an extra amplitude modulation on one deformable mirror configuration to create an uncorrelated wave-front, which is a critical procedure for wave-front sensing. The simulation shows that the reconstructed wave-front is consistent with the original wave-front theoretically, which indicates that such an algorithm is a promising technique for the wave-front measurement for the high-contrast imaging.

description: Organic phase change materials (PCMs) are used for energy storage and thermal management in numerous applications, including space missions. Their low thermal conductivity, however, has discouraged wider use. Recent studies showed that incorporating a free surface can significantly enhance heat transfer via thermocapillary convection and improve performance. Analysis of PCM melting in rectangular domains revealed the detrimental influence of a final conduction-dominated stage, which limits performance. Improvements based on trapezoidal and triangular containers have already been assessed. Here, we propose a new triangle-like shape with a curved \"hypotenuse\" that can achieve an additional enhancement factor of 1.2 in short containers.

description: To understand the nature of supernovae and neutron star (NS) formation, as well as binary stellar evolution and their interactions, it is important to probe the distribution of NS masses. Until now, all double NS (DNS) systems have been measured to have a mass ratio close to unity (q $\geq$ 0.91). Here we report the measurement of the individual masses of the 4.07-day binary pulsar J0453+1559 from measurements of the rate of advance of periastron and Shapiro delay: The mass of the pulsar is 1.559(5) $M_{\odot}$ and that of its companion is 1.174(4) $M_{\odot}$; q = 0.75. If this companion is also a neutron star (NS), as indicated by the orbital eccentricity of the system (e=0.11), then its mass is the smallest precisely measured for any such object. The pulsar has a spin period of 45.7 ms and a spin derivative of 1.8616(7) x$10^-19$; from these we derive a characteristic age of ~ 4.1 x $10^9$ years and a magnetic field of ~ 2.9 x $10^9$ G,i.e, this pulsar was mildly recycled by accretion of matter from the progenitor of the companion star. This suggests that it was formed with (very approximately) its current mass. Thus NSs form with a wide range of masses, which is important for understanding their formation in supernovae. It is also important for the search for gravitational waves released during a NS-NS merger: it is now evident that we should not assume all DNS systems are symmetric.

description: The emergence of antimicrobial resistance worldwide has threatened the therapeutic viability of antimicrobial drugs. Non-typhoidal Salmonella enterica subspecies enterica sickens 1.2 million Americans annually and can be transmitted to people through food, water, animal contact and animal environments. This paper represents the first description of the epidemiology of multistate zoonotic outbreaks of non-typhoidal Salmonella in the US and their representative patterns of antimicrobial susceptibility and resistance of patient isolates. It evaluates the rate of concordance between traditional phenotypic and newer genotypic predicted antimicrobial resistance patterns to in the context of Salmonella surveillance and treatment in the US that rely on the cooperation between local, state and federal public health organizations. Given the complex public health challenges public health leaders are urged to take the role of chief health strategists by using transformational leadership and systems thinking to engage stakeholders in the One-Health effort to combat zoonotic salmonellosis and antimicrobial resistance.

The test case of round synthetic jet in a cross-flow, is used to validate the dynamic mesh model for predicting the actuator driven flow. The hump model with oscillatory control is used for studying the effect of jet momentum and frequency in suppressing the bubble. The estimate of reduced frequencies and momentum coefficients for the expected pressure recovery has been found, and implemented in a representative configuration to understand the efficacy of the control device in suppressing flow separation and consequent enhancement in lift.

description: In this Letter we prove a simple theorem in quantum information theory, which implies that bulk operators in the Anti-de Sitter / Conformal Field Theory (AdS/CFT) correspondence can be reconstructed as CFT operators in a spatial subregion $A$, provided that they lie in its entanglement wedge. This is an improvement on existing reconstruction methods, which have at most succeeded in the smaller causal wedge. The proof is a combination of the recent work of Jafferis, Lewkowycz, Maldacena, and Suh on the quantum relative entropy of a CFT subregion with earlier ideas interpreting the correspondence as a quantum error correcting code.

description: Position sensitive detectors based on gaseous scintillation proportional counters with Anger-type readout are being used in several research areas such as neutron detection, search for dark matter and neutrinoless double beta decay. Design and optimization of such detectors are complex and time consuming tasks. Simulations, while being a powerful tool, strongly depend on the light transport models and demand accurate knowledge of many parameters, which are often not available. Here we describe an alternative approach based on the experimental evaluation of a detector using an isotropic point-like light source with precisely controllable light emission properties, installed on a 3D positioning system. The results obtained with the developed setup at validation conditions, when the scattered light is strongly suppressed, show good agreement with simulations.

description: Orbit determination is possible for a chaotic orbit of a dynamical system, given a finite set of observations, provided the initial conditions are at the central time. In a simple discrete model, the standard map, we tackle the problem of chaotic orbit determination when observations extend beyond the predictability horizon. If the orbit is hyperbolic, a shadowing orbit is computed by the least squares orbit determination. We test both the convergence of the orbit determination iterative procedure and the behaviour of the uncertainties as a function of the maximum number $n$ of map iterations observed. When the initial conditions belong to a chaotic orbit, the orbit determination is made impossible by numerical instability beyond a computability horizon, which can be approximately predicted by a simple formula. Moreover, the uncertainty of the results is sharply increased if a dynamical parameter is added to the initial conditions as parameter to be estimated. The uncertainty of the dynamical parameter decreases like $n^a$ with $a<0$ but not large (of the order of unity). If only the initial conditions are estimated, their uncertainty decreases exponentially with $n$. If they belong to a non-chaotic orbit the computational horizon is much larger, if it exists at all, and the decrease of the uncertainty is polynomial in all parameters, like $n^a$ with $a\simeq 1/2$. The Shadowing Lemma does not dictate what the asymptotic behaviour of the uncertainties should be. These phenomena have significant implications, which remain to be studied, in practical problems of orbit determination involving chaos, such as the chaotic rotation state of a celestial body and a chaotic orbit of a planet-crossing asteroid undergoing many close approaches.

description: Die jüngsten Entwicklungen des wissenschaftlichen Publikationsmarkts und die wissenschaftspolitische Bestärkung von Open Access und Open Science, erfordern innerhalb von Informationsinfrastrukturen neue Wege des Lizenz- und Rechtemanagements. Ohne die entsprechende Bereitstellung von Lizenzinformationen oder Hinweisen zur Verwendung wird es kaum möglich sein, den im Kontext einer digitalen Publikation sehr zahlreichen Anwendungsfällen realistisch gerecht zu werden. Aus diesem Grund wird für wissenschaftliche Bibliotheken und Repositorien ein professionelles und weitestgehend automatisiertes Rechtemanagement digitaler Publikationen immer bedeutender. Mithilfe von qualitativen Forschungsmethoden wurden für diese Arbeit leitfadengestützte Epert:inneninterviews geführt und ausgewertet, um herauszufinden, wie Informationsinfrastruktureinrichtungen mit der Abbildung von Rechteinformationen sowie mit der Zugriffssteuerung auf ihre digitalen Objekte umgehen und welche Probleme sie im Kontext des Rechtemanagements sehen. Daraus ergeben sich die Anforderungen, die für ein effektives Rechtemanagement, als notwendig erachtet werden. Zum Beispiel wird die Möglichkeit zur Dokumentation von Rechtsgrundlagen gewünscht, um die Transparenz des Rechtemanagements sicherzustellen und einen umfassenden Überblick über die verschiedenen Rechtesituationen zu gewährleisten. Grundsätzlich besteht der Bedarf, das Rechtemanagement innerhalb des Systems granularer und flexibler zu gestalten. Ein vielfach ausgesprochenes Desiderat ist der fachliche Austausch innerhalb der Community, um eine umfassendere Expertise aufzubauen, einheitliche Standards sowie einen bestimmten Konsens für das Rechtemanagement zu etablieren. Abschließend werden auf der Basis der genannten Bedarfe einige Lösungsansätze für ein optimiertes Rechtemanagementsystem diskutiert.

description: In this paper, the installation effects on hovering air-vehicle performance are discussed. Tractor configuration is considered which exhibits two installation effects on the vehicle performance. The first is the vertical drag due to the immersed installations in the propeller wake. Second is the propeller performance as influenced by the installation wake clogging. An analytic model is suggested for the former and an experiment was done to substantiate an empiric model for the latter. The paper shed light on the procedure of thrust and power bookkeeping, which should be taken into consideration during estimating installed propellers for hovering air vehicles.
Public Policy Implications for Access to Remote Monitoring and Consultation in Healthcare

description: Enrollees of Medicare and Medicaid are going to grow dramatically in the next ten years, due in part to the new health reform legislation and the aging baby boomer generation (UnitedHealth Center for Health Reform Modernization, 2010). This growth, in concert with concerns about aggregate health care costs, calls for more efficient and effective delivery of long term supports and services (Stone Weiner, 2001). One approach to address this specific healthcare demand is an effort to increase use of telehealth1 (Field Grigsby, 2002). The use of telehealth in the form of remote monitoring and consultation would increase accessibility to long term supports by leveraging technology to provide medical care when distance separates the participants (American Association of Telemedicine). At this time, Medicare and Medicaid do not broadly reimburse for telehealth services (Neumann Tunis, 2010). There are provisions in the Patient Protection and Affordable Care Act (HR 3590 2010) that would allow for greater use of technology to deliver long term services and supports and set the stage for greater public reimbursement for such services through Medicare and Medicaid. This paper will explore the policy issues related to telehealth included in the Patient Protection and Affordable Care Act (PPACA), and how it may increase accessibility to telehealth services for Medicaid and Medicare enrollees seeking long term monitoring and consultation services.

description: In this paper, we propose a Mixed-Integer Linear Programming (1v[[LP) based method for generating an optimal image acquisition schedule. We especially consider a Terrestrial Mapping problem, which is defined as finding an acquisition schedule for obtaining images of a certain predefined area. We consider an Electro-Optical (EO) satellite with a push-broom type imager, occupying a Sun-Synchronous Orbit (SSO). By exploiting the properties of SSO, the terrestrial mapping problem is converted into a MILP problem, which could be efficiently solved using commercial solvers. As a result, we propose multiple variations of the terrestrial mapping problem which could be optimized in the MILP framework.

description: Let $G$ be a real linear algebraic group and $L$ a finitely generated cosimplicial group. We prove that the space of homomorphisms $Hom(L_n,G)$ has a homotopy stable decomposition for each $n\geq 1$. When $G$ is a compact Lie group, we show that the decomposition is $G$-equivariant with respect to the induced action of conjugation by elements of $G$. The spaces $Hom(L_n,G)$ assemble into a simplicial space $Hom(L,G)$. When $G=U$ we show that its geometric realization $B(L,U)$, has a non-unital $E_\infty$-ring space structure whenever $Hom(L_0,U(m))$ is path connected for all $m\geq1$.
