Evolution of circumbinary planets around eccentric binaries: The case of Kepler-34

description: The existence of planets orbiting a central binary star system immediately raises questions regarding their formation and dynamical evolution. Recent discoveries of circumbinary planets by the Kepler space telescope has shown that some of these planets reside close to the dynamical stability limit where it is very difficult to form planets in situ. For binary systems with nearly circular orbits, such as Kepler-38, the observed proximity of planetary orbits to the stability limit can be understood by an evolutionary process in which planets form farther out in the disk and migrate inward to their observed position. The Kepler-34 system has a high orbital eccentricity of 0.52. Here, we analyse evolutionary scenarios for the planet observed around this system using two-dimensional hydrodynamical simulations. The highly eccentric binary opens a wide inner hole in the disk which is also eccentric, and displays a slow prograde precession. As a result of the large, eccentric inner gap, an embedded planet settles in a final equilibrium position that lies beyond the observed location of Kepler-34 b, but has the correct eccentricity. In this configuration the planetary orbit is aligned with the disk in a state of apsidal corotation.To account for the closer orbit of Kepler-34 b to the central binary, we considered a two-planet scenario and examined the evolution of the system through joint inward migration and capture into mean-motion resonances. When the inner planet orbits inside the gap of the disk, planet-planet scattering ensues. While often one object is thrown into a large, highly eccentric orbit, at times the system is left with a planet close to the observed orbit, suggesting that Kepler 34 might have had two circumbinary planets where one might have been scattered out of the system or into an orbit where it did not transit the central binary during the operation of Kepler.

description: A potential able to capture the properties and interactions of curved polycyclic aromatic hydrocarbons (cPAHs) was developed and used to investigate the nucleation behavior and structure of nascent soot particles. The flexoelectric charge polarization of cPAHs caused by pentagon integration was included through the introduction of off-site virtual atoms, and enhanced dispersion interaction parameters were fitted. The electric polarization and intermolecular interactions of cPAHs were accurately reproduced compared to ab initio calculations. This potential was used within molecular dynamics simulations to examine the homogeneous and heterogeneous nucleation behavior of the cPAH corannulene and planar PAH coronene across a range of temperatures relevant to combustion. The enhanced interactions between cPAHs and potassium ions resulted in significant and rapid nucleation of stable clusters compared to all other systems, highlighting their importance in soot nucleation. In addition, the resulting cPAH clusters present morphologies distinct from the stacked planar PAH clusters.

description: In this Letter, I report on a novel scheme for beam stacking without any beam emittance dilution using a barrier rf system in synchrotrons. The general principle of the scheme called longitudinal phase-space coating, validation of the concept via multi-particle beam dynamics simulations applied to the Fermilab Recycler, and its experimental demonstration are presented. In addition, it has been shown and illustrated that the rf gymnastics involved in this scheme can be used in measuring the incoherent synchrotron tune spectrum of the beam in barrier buckets and in producing a clean hollow beam in longitudinal phase space. The method of beam stacking in synchrotrons presented here is the first of its kind.

Assessing Patient Outcomes: Quality of Life and Cost Associated with the Use of Left Ventricular Assist Devices in the Treatment of End Stage Heart Failure
Creators: name: Eigenhuis, Joshua
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: This literature review examines the use of left ventricular assist devices (LVAD’s) in the treatment of End Stage Heart Failure (ESHF) and patient outcomes. The American Heart Association defines Heart Failure as a chronic, progressive condition, in which the heart muscle is incapable of pumping enough blood to meet the body’s blood and oxygen demands. Currently, about 5.7 million Americans are living with Heart Failure, while roughly 10% have ESHF (American Heart Association, 2015). This literature review examines prescription medications, implantable devices (specifically LVAD’s) and heart transplants, their cost-effectiveness, and impact on symptom management and quality of life in the treatment of End Stage Heart Failure (ESHF). Despite the various treatment modalities none have yet been established as the gold standard. While much research focused on cost and mortality, findings were limited in relation to quality of life pre and post LVAD placement. Therefore future recommendations include utilizing a tool to evaluate clinical effectiveness of LVAD’s and improved quality of life pre and post-operatively, providing patients with the necessary knowledge to make informed, individualized decisions on which treatment modality to pursue.
A Hierarchical Bayes Ensemble Kalman Filter

Subjects: subject: Data Analysis, Statistics and Probability (physics.data-an)

description: A new ensemble filter that allows for the uncertainty in the prior distribution is proposed and tested. The filter relies on the conditional Gaussian distribution of the state given the model-error and predictability-error covariance matrices. The latter are treated as random matrices and updated in a hierarchical Bayes scheme along with the state. The (hyper)prior distribution of the covariance matrices is assumed to be inverse Wishart. The new Hierarchical Bayes Ensemble Filter (HBEF) assimilates ensemble members as generalized observations and allows ordinary observations to influence the covariances. The actual probability distribution of the ensemble members is allowed to be different from the true one. An approximation that leads to a practicable analysis algorithm is proposed. The new filter is studied in numerical experiments with a doubly stochastic one-variable model of "truth". The model permits the assessment of the variance of the truth and the true filtering error variance at each time instance. The HBEF is shown to outperform the EnKF and the HEnKF by Myrseth and Omre (2010) in a wide range of filtering regimes in terms of performance of its primary and secondary filter.

What Transitional Care Interventions are Used in the Care of Burn Patients?  An Integrative Review
Creators: name: Cromeens, Martha Grace
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: Patients with burn wounds present complex and long-term challenges to healthcare
providers.  A recent study revealed burn patients experience 30-day readmission rates as
high as 25% (Mandell, Pham, Klein, 2013).  Readmission rates represent a costly
challenge.  In the recent past, transitional care has been offered as a possible solution for
high readmission rates, unexpected ED visits, elevated mortality rates, and high costs.
The purpose of this integrative literature review is to identify the potential need for
transitional care in patients with burn injuries by pinpointing key elements of seminal
works in transitional care and analyzing discharge planning in the burn patient population
within this context.  Cooper’s 5-stage method (1998) was used to systematically searched
the literature.  Search terms included transitional care, discharge planning, home care
planning and burn patients/wounds/injuries.  After applying exclusion criteria, 10 articles
covering 8 transitional care frameworks were selected, revealing 14 common transitional
care interventions.  Discharge and home care planning articles were also reviewed for
studies predating the body of transitional care research.  Six discharge/home care planning
articles also met study criteria.  These works, all descriptive in nature, shared 16 common
interventions. The 6 home care and discharge planning articles for burn patients represent
a lineage predating the transitional care frameworks currently used in healthcare.  Burn
units have a strong history of preparing for patient transitions from hospital care.
However, the lack of current research examining the implementation of transitional care
protocols in burn units combined with high readmission rates indicate a need for further
development and investigation.
La Iena di San Giorgio. Da leggenda popolare a mito burattinesco

description: Quella della Iena di San Giorgio è una leggenda popolare entrata a far parte dei repertori di diverse famiglie d’arte burattinaia. Tra i copioni pubblicati intorno alla storia del macellaio assassino, quello di Gualberto Niemen ricostruisce, a fine secolo, la memoria dello spettacolo che portava in giro nella prima metà del Novecento. Proprio una sua rappresentazione ispira Guido Ceronetti a farne una moderna riscrittura, che diventa il primo testo rappresentato dal Teatro dei Sensibili (1970). Sempre a inizio anni ’70, Giuliano Scabia rivisita la leggenda per renderla racconto mitico di un mondo distrutto dal consumismo. Attraverso il confronto tra le versioni si vedrà come la vicenda, nel corso di un secolo, si trasformi da storia moralizzatrice ad affermazione dell’ineluttabilità del male.

Quantum Quench Dynamics in the Transverse Field Ising Model at Non-zero Temperatures

description: The recently discovered dynamical phase transition denotes non-analytic behavior in the real time evolution of quantum systems in the thermodynamic limit and has been shown to occur in different systems at zero temperature [Heyl et al., Phys. Rev. Lett. 110, 135704 (2013)]. In this paper we extend the analysis to non-zero temperature by studying a generalized form of the Loschmidt echo, the work distribution function, of a quantum quench in the transverse field Ising model. Although the quantitative behavior at non-zero temperatures still displays features derived from the zero temperature non-analyticities, it is shown that in this model dynamical phase transitions do not exist if $T>0$. This is a consequence of the system being initialized in a thermal state. Moreover, we elucidate how the Tasaki-Crooks-Jarzynski relation can be exploited as a symmetry relation for a global quench or to obtain the change of the equilibrium free energy density.

Gendered labor market decisions among queer and straight couples
Creators: name: Hassel, Margaret
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: Using data from the American Community Survey, I use gay families as a “control” for straight families to examine the degree to which gender impacts families’ choices about who stays home and who goes to work when the family has children. In most families, the person who earns a higher hourly wage works more hours, especially once the family has children. This arrangement maximizes household income. However, there are other concerns that might override this objective – one parent might prefer spending time with children or dislike their job. I find that gay parents experience an earnings gap “bump” of between $4,000 and $5,400 when they have children, characterized by the higher earning partner working about one more day per week than the low earning partner (compared to about half a day more when the couple does not have children). This is the gap we can expect when gender is no factor. When we turn to straight couples, however, it becomes clear that gender plays a role, over and above simple personal preferences also present in gay relationships. After controlling for other factors, gay couples experience a post-children bump in their earnings gap that is about 10 percentage points larger than for female-high earner straight couples, and about 10 percentage points smaller than for male-high earner straight couples. High earning women underspecialize in market production compared to what we would expect in a non-gendered relationship, and high earning men overspecialize in market production.

description: Measurements of the transverse momentum spectra of light flavor particles at intermediate and high pT are an important tool for QCD studies. In pp collisions they provide a baseline for perturbative QCD, while in Pb-Pb they are used to investigate the suppression caused by the surrounding medium. In p-Pb collisions, such measurements provide a reference to disentangle final from initial state effects and thus play an important role in the search for signatures of the formation of a deconfined hot medium. While the comparison of the p-Pb and Pb-Pb data indicates that initial state effects do not play a role in the suppression of hadron production observed at high pT in heavy ion collisions, several measurements of particle production in the low and intermediate pT region indicate the presence of collective effects.

FUTURES WITH A FUTURE: An Introduction to the Positive Futures Movement
Creators: name: Lutterman, Ariana
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: Current societal narratives are rife with negative, dystopian, fearful images of the future. In this paper, I propose that there is a wave of thinkers, activists, individuals, and groups who comprise a movement that does not yet recognize itself as a movement: the positive futures movement. The positive futures movement acknowledges the full complexity and gravity of the multiple crises facing humanity in the future, yet rather than subscribe to conventional dystopia, the movement advocates action and engagement in creating a desirable future. From a wide array of backgrounds and perspectives, those within the movement generally share a common way to frame crises as well as a belief that action taken now can effect a more positive future for humanity and the planet. This text hope to illustrate the commonalities of the positive future movement so that it may gain power in identifying as such, both through its frame of crisis and an analysis of what positivity means to those within it.
Potential Role of Neutrophil Gelatinase-Associated Lipocalin (NGAL) as a Mediator of Liver Injury and Fibrogenesis in Alcoholic Hepatitis
Creators: name: Patel, Palak K.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: Background: Alcoholic hepatitis (AH) is a severe form of alcoholic liver disease (ALD) associated with significant short-term mortality. Existing treatment therapies are not completely effective, highlighting the need to identify molecular drivers in AH. NGAL has recently been identified as one of the most overexpressed genes in patients with AH.
Aims: To investigate the role of NGAL as a potential target for therapy in AH using a translational approach including human samples and animal models.
Methods: NGAL expression was analyzed in patients with AH, animal models of liver inflammation and fibrogenesis, and cell lines of human hepatocytes. Fibrosis- and inflammation-marker genes were analyzed for expression in hepatic stellate cell (HSC) cell lines treated with NGAL. RNA was extracted from all samples and gene expression of cDNA was measured using real-time qPCR analysis.
Results: Gene expression of NGAL in patients with AH had a 44-fold increase in comparison to several other liver diseases. Animal models of liver inflammation and fibrosis had increased NGAL expression. Although cell lines of human hepatocytes exhibited greater NGAL expression than HSC cell lines, there was no noticeable increase in NGAL expression with subsequent pro-inflammatory induction of hepatocyte cell lines. HSC cell lines showed increased expression of several markers of fibrosis and inflammation with NGAL treatment.
Conclusion: NGAL is overexpressed in patients with AH and in animal models of liver inflammation and fibrosis and it exerts fibrogenic and inflammatory effects in hepatic stellate cells. Results suggest that NGAL may be a potential target for therapy in AH. Further studies should be done to more fully explore the nature of NGAL overexpression in AH.

description: The discovery of materials with improved functionality can be accelerated by rational material design. Heusler compounds with tunable magnetic sublattices allow to implement this concept to achieve novel magnetic properties. Here, we have designed a family of Heusler alloys with a compensated ferrimagnetic state. In the vicinity of the compensation composition in Mn-Pt-Ga, a giant exchange bias (EB) of more than 3 T and a similarly large coercivity are established. The large exchange anisotropy originates from the exchange interaction between the compensated host and ferrimagnetic clusters that arise from intrinsic anti-site disorder. We demonstrate the applicability of our design concept on a second material, Mn-Fe-Ga, with a magnetic transition above room temperature, exemplifying the universality of the concept and the feasibility of room-temperature applications. Our study points to a new direction for novel magneto-electronic devices. At the same time it suggests a new route for realizing rare-earth free exchange-biased hard magnets, where the second quadrant magnetization can be stabilized by the exchange bias.

Staff training in gambling related disorders and responsible gambling and what works: a pre-registered systematic review
Creators: name: Beckett, Michelle

Publisher: name: Open Science Framework
Year: 2022

description: Staff training in gambling related disorders and responsible gambling is often included in gaming operators’ harm-minimisation strategies. Gaming jurisdictions often require that operators provide staff with formal training in gambling disorder awareness, and that venues comply with harm-minimisation practices. However, there is variance in the format, intensity, and perceived effectiveness of training programs, and no best practice has been established. Moreover, there is likely considerable variability in what outcomes are measured, and the specific method of measurement used. Additionally, staff members often report wanting further training in responding to cases where customers are showing signs of excessive gambling. We are conducting a systematic review to investigate the core components of staff training in responsible gambling that are described, the outcomes of core components that are evaluated, and investigate the potential impacts on staff members and gamblers. Careful considerations will be made regarding the methodological properties (including evaluation analyses, risk of bias, and level of evidence), and outcomes in the studies of staff training programs aimed at alleviating or preventing gambling-related harms. Following data extraction from articles meeting the inclusion criteria, a narrative synthesis and review of the findings will be written.
La Scapigliatura nell’inferno di Milano

description: Il saggio prende in esame la presenza dell’Inferno di Dante nella produzione giornalistica e narrativa della Scapigliatura democratica dedicata ai bassifondi di Milano. A partire dalla fine degli anni Settanta del XIX secolo, infatti, nei reportage di autori ‘scapigliati’ come Paolo Valera, Francesco Giarelli e Lodovico Corio, è possibile rinvenire numerosi riferimenti alla prima cantica dantesca, tanto sul piano intertestuale, quanto su quello strutturale. A questo proposito, il saggio intende evidenziare le forme e le motivazioni ideologiche che stanno alla base di tale caratterizzazione infernale, concentrandosi in particolare sulla funzione dell’Inferno dantesco quale serbatoio di immagini e motivi capaci di avvalorare, presso il pubblico, la visione delle zone più nascoste della “capitale morale” d’Italia.

Dorothea & Isabel: Nineteenth-Century Women Idealists’ Reimagining Marriage and Pursuing Vocation
Creators: name: Gebbia, Lauren
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: The complex themes of George Eliot’s Middlemarch (1871) and Henry James’ The Portrait of a Lady (1881) have attracted intensive study over the years, and they have drawn my interest as well, given these texts’ ability to speak both to their contemporary cultural concerns regarding women’s lives and to enduring questions of human idealism, vocation, imagination, and decision-making. The novels offer compelling representations of idealistic young women protagonists who creatively grapple with gender-based restrictions on their opportunities to pursue personal ambitions. Though the situation for women in western society has changed greatly since the late nineteenth century, the essential question in the hearts of Dorothea and Isabel is the same that I and my peers seek to answer today: How will I discover my unique vocation and make a meaningful contribution to my world? The exact types of societal pressure contemporary women experience may differ widely from those of the late nineteenth century, yet the demands on individual women to negotiate opportunities creatively, to plan, to decide, and to act are consistent. Dorothea and Isabel approach this problem from the basis of their imaginative idealism. Examining the psychology and the lives of these characters can suggest how we, like Dorothea and Isabel, may also creatively endeavor to work around socially-imposed limitations to pursue our ambitions. We may also learn from their shortcomings.
Latent Correlations Between Trait Aggression and Trait Antagonism

description: In this follow-up study, I will again test the prediction that the antagonism (low agreeableness) factor of the Five Factor Model (FFM) of personality will account for the overwhelming majority of the variance in trait aggression (latent correlations > .60). Other FFM factors will exhibit latent correlations < |.60|. Exploratory analyses with the IPIP-NEO-120 FFM and Brief Aggression Questionnaire supported these predictions. Subsequent confirmatory analyses with the Big Five Inventory and full Buss-Perry Aggression Questionnaire only weakly supported these predictions. This may be due to the different content in the Agreeableness subscales of the NEO and BFI. I will now seek to confirm the exploratory analyses by replicating them in a dataset from an existing laboratory study with 424 undergraduate participants who completed the 12-item Brief Aggression Questionnaire measure of trait aggression and the 60-item NEO-Five Factor Inventory scale. I will use the lavaan package for R to run factor analyses for each FFM facet using the following design: LatentCorr.mod <- 'BAQtotal =~ BAQphysical + BAQverbal + BAQanger + BAQhostility IPIPagreeableness =~ NEO.4 + NEO.9 + NEO.14 + NEO.19 + NEO.24 + NEO.29 + NEO.34 + NEO.39 + NEO.44 + NEO.49 + NEO.54 + NEO.59 IPIPconscientious =~ NEO.5 + NEO.10 + NEO.15 + NEO.20 + NEO.25 + NEO.30 + NEO.35 + NEO.40 + NEO.45 + NEO.50 + NEO.55 + NEO.60 IPIPextraversion =~ NEO.2 + NEO.7 + NEO.12 + NEO.17 + NEO.22 + NEO.27 + NEO.32 + NEO.37 + NEO.42 + NEO.47 + NEO.52 + NEO.59 IPIPneuroticism =~ NEO.1 + NEO.6 + NEO.11 + NEO.16 + NEO.21 + NEO.26 + NEO.31 + NEO.36 + NEO.41 + NEO.46 + NEO.51 + NEO.56 IPIPopenness =~ NEO.3 + NEO.8 + NEO.13 + NEO.18 + NEO.23 + NEO.28 + NEO.33 + NEO.38 + NEO.43 + NEO.48 + NEO.53 + NEO.58' fitmod <- cfa(LatentCorr.mod, data=[Dataset], missing='ML') summary(fitmod, fit.measures=TRUE, standardized = TRUE) I will then report the standardized latent correlations for each FFM factor. I will interpret that my hypotheses are supported if the latent correlation between trait aggression and agreeableness is more negative than -.60, and if the latent correlations between trait aggression and the four other FFM factors are < |.60|.

The new CFTs are based on holomorphic currents with an operator product expansion characterized by a positive integer-valued matrix $K_{AB}$. We use the Sugawara construction to compute the energy-momentum tensor, the central charge, and the spectrum of conformal dimensions of the CFTs based on this algebra. We also construct a set of genus-$1$ characters and show that they fulfil a representation of the modular group $\text{SL}(2,\mathbb{Z})$ up to a modular anomaly.

The Influence of Lower Extremity Movement Quality and Body Composition on Lower Extremity Bone Stress Injury Occurrence in Division I Cross Country Athletes

Year: 2016

description: Bone stress injuries (BSIs) are prevalent among cross-country athletes. This study aims to
identify lower extremity movement quality and body composition characteristics that influence
BSIs. 37 collegiate cross-country athletes were tested at preseason. Biomechanical data were
obtained through visual observation of overhead and single leg squats. Body composition data
were gathered via Dual-Energy X-Ray Absorptiometry scans. Injury data were recorded in an
electronic medical record for one year post-testing. Chi-square analyses examined biomechanical
data, and independent samples t-tests examined body composition data. Females and athletes
with a lower BMI, lower mass, and lower lean mass are more likely to sustain a BSI. Injured leg
lean mass was less than leg lean mass of uninjured athletes. Biomechanical assessments were
unable to discern between the two groups. Females and athletes with low BMI or small lower
extremity lean mass should be monitored for implementation of injury prevention programs to
mitigate BSI occurrence.
Drosophila Marcal1 in Double-Strand Break Repair by Synthesis Dependent Strand Annealing
Creators: name: Buzhardt, Emily
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: It is important to study DNA damage such as double strand breaks (DSBs) because DSBs can cause cancer and genomic instability. DSB are repaired by homologous recombination which can cause a crossover or non-crossover event. Crossovers are detrimental because they can lead to genomic instability. Synthesis dependent strand annealing (SDSA) is a form of double strand break repair (DSBR) without crossovers. It is beneficial because it protects against genomic instability. This experiment seeks to determine the role of Marcal1 in SDSA in Drosophila melanogaster using a P{wa} P-element system in a fly line with a Marcal1 deletion. Marcal1 was studied because we have evidence that it is involved in some aspect of DSBR; however, it is unclear about which aspect of DSBR. It is hypothesized that when Marcal1 is deleted and DSBs are induced in the fly line, there will be an increase in aberrant repair. Results show an increase in aberrant repair and a decrease in SDSA, indicating that Marcal1 has a role in SDSA. PCR results of the aberrant repair flies found no statistical difference in the tract lengths between wild type flies and Marcal1 mutant flies.

description: Comparisons between the EU’s success in Romania and failure in Hungary raise an
important question: what explains the variation in outcomes given the EU’s attempts in both
cases to compel a member state government to reverse illiberal actions? I argue that three factors
are most important in explaining this variation. First is trust: if the citizens in the targeted
member state place a high level of trust in the EU and a relatively low level of trust in the
national government, the government will be more likely to capitulate to EU demands for fear of
paying high domestic political costs for defying the EU. Second is friends in high places: if the
government is protected from material sanctions by a powerful party group within the European
Parliament, the EU will be less likely to use material sanctions against that member state. Third
is domestic contention: if the nature of the illiberal actions is such that the government has
successfully curbed domestic political competition, the targeted state will be less likely to
capitulate to EU demands, since they will have less reason to fear domestic electoral
consequences of non-compliance or of incurring sanctions.

description: Radio telescopes are used to accurately measure the time of arrival (ToA) of radio pulses in pulsar timing experiments that target mostly millisecond pulsars (MSPs) due to their high rotational stability. This allows for detailed study of MSPs and forms the basis of experiments to detect gravitational waves. Apart from intrinsic and propagation effects, such as pulse-to-pulse jitter and dispersion variations in the interstellar medium, timing precision is limited in part by the following: polarization purity of the telescope's orthogonally polarized receptors, the signal-to-noise ratio (S/N) of the pulsar profile, and the polarization fidelity of the system. Using simulations, we present how fundamental limitations in recovering the true polarization reduce the precision of ToA measurements. Any real system will respond differently to each source observed depending on the unique pulsar polarization profile. Using the profiles of known MSPs we quantify the limits of observing system specifications that yield satisfactory ToA measurements, and we place a practical design limit beyond which improvement of the system results in diminishing returns. Our aim is to justify limits for the front-end polarization characteristics of next generation radio telescopes, leading to the Square Kilometre Array (SKA).

description: Nested words introduced by Alur and Madhusudan are used to capture structures with both linear and hierarchical order, e.g. XML documents, without losing valuable closure properties. Furthermore, Alur and Madhusudan introduced automata and equivalent logics for both finite and infinite nested words, thus extending Büchi's theorem to nested words. Recently, average and discounted computations of weights in quantitative systems found much interest. Here, we will introduce and investigate weighted automata models and weighted MSO logics for infinite nested words. As weight structures we consider valuation monoids which incorporate average and discounted computations of weights as well as the classical semirings. We show that under suitable assumptions, two resp. three fragments of our weighted logics can be transformed into each other. Moreover, we show that the logic fragments have the same expressive power as weighted nested word automata.

description: Diabetes mellitus is a known metabolic disorder characterized by altered insulin secretion or responsiveness. Recently, a potential association between diabetes and environmental exposures has been described, in which environmental compounds have been identified as potential diabetogens. With diabetes prevalence and industrial growth rising in many middle- and low-income countries, it is imperative we look further into the association between heavy metals and diabetes mellitus. Interactions between iAsIII and heavy metals may exhibit differing effects on insulin secretion machinery than just individual heavy metals. In previous studies, trivalent inorganic arsenic (iAsIII) has been identified as an inhibitor of insulin secretion in isolated mouse islets. In addition to iAsIII, heavy metals, notably zinc (Zn), manganese (Mn) and cadmium (Cd), have also been found to be associated with alteration of insulin secretion. INS-1 (832/13) rat insulinoma cells were treated for 24 hours with varying concentrations of each of the aforementioned heavy metals. When co-exposed with Zn and Cd, iAsIII acted as the primary inhibitor of insulin secretion in the β-cells. Co-exposure of Mn and 1 μM iAsIII, exhibited a significant decrease in insulin secretion at the 25 and 50 μM Mn concentrations compared to 1 μM iAsIII exposure alone. There was no significant difference in insulin secretion between the Mn and iAsIII co-exposure and Mn alone treatment groups at the 25 and 50 μM Mn concentrations, suggesting Mn as a primary driver of insulin secretion inhibition at higher concentrations. Additionally, 24-hour 1 μM iAsIII exposure to INS-1 (832/13) cells caused a significant decrease in mitochondrial oxygen consumption rate (OCR) under energy-demanding conditions, identifying mitochondria as targets for iAsIII in β-cells. This study examines the impact of heavy metals and their mixtures with iAsIII on insulin secretion in INS1 (832/13) rat pancreatic β-cells. From these results, we conclude that water mixtures containing certain heavy metals in mixture with iAsIII may pose significant danger to pancreatic β-cell function.
Effect of Combining Solar Output and Increased Distance between Solar Projects on Variability and Performance

description: The present study assesses the benefit of combining solar projects with the goal of decreasing production variability across a day and increasing solar output during peak demand. The significance of distance was also explored in this study to determine if the decrease in production caused by clouds could be avoided by increasing the distance between samples. The analysis was conducted using a data set containing production levels in fifteen minute intervals for 115 projects across one year provided by Southern California Edison. The results found that daily variability is improved 46% and production during peak demand is improved 3.6% when combining the output of five projects together, compared to the average of the individual output. Distance between the projects was found to have no significant impact within the range tested. Distance was regressed upon weekly minimum production, daily production, daily production within specific climate zones, daily production within specific climate zones on cloudy days, and in all regressions the coefficient for distance was found to be insignificant for the tested range of 10-150 miles. It was found however that adjacent projects experience a weekly minimum just under 4% lower than combinations of size five. The data set did not contain the appropriate data to make conclusions under ten miles. Based on the findings of the study it is recommended that solar projects are grouped in combinations of at least size five with an average of at least ten miles apart to decrease variability and increase production at peak demand.
Protesting the “Condonation of Savagery”: American Catholics and Non-Involvement in the Spanish Civil War

description: There was a confluence of factors that impeded U.S. support for the Loyalists during the Spanish Civil War (1936-1939), particularly that America’s European allies adopted non-involvement. Using contemporary newspapers, government documents, letters to Franklin D. Roosevelt and the Department of State, and a number of Catholic organization archives, this study advances a further reason American aid was hindered.       This paper investigates the extent of American Catholic protests against any form of U.S. involvement in the Spanish Civil War. It argues that Catholics were central to the domestic considerations to retain the non-involvement policy regarding the war. Due to the ardent concern with the reported persecution of Catholics in Spain, Catholic organizations, press, clergy, and politicians protested any involvement that would support the Loyalists. These protests occurred at all levels of American society. Within the press, priests denounced pro-Loyalist Protestant ministers in the New York Times. In government, Catholic politicians denounced fundraising for the Loyalists while other Catholics formed committees and sent letters to Roosevelt opposing reforms to neutrality legislation. Among the public, Catholics impeded the non-governmental fundraising of the North American Committee to Aid Spanish Democracy by protesting and censuring its speakers and events.

description: In the present work the rotation of polarization vector due to the gravitational field of a rotating body has been derived, from the general expression of Maxwell's equation in the curved space-time. Considering the far field approximation (i.e impact parameter is greater than the Schwarzschild radius and rotation parameter), the amount of rotation of polarization vector as a function of impact parameter has been obtained for a rotating body (considering Kerr geometry). Present work shows that, the rotation of polarization vector can not be observed in case of Schwarzschild geometry. This work also calculates the effect, considering prograde and retrograde orbit for the light ray. Although the present work demonstrates the effect of rotation of polarization vector for electromagnetic wave (light ray), but it confirms that there would be no net polarization of electromagnetic wave due to the curved space-time geometry.
