Statistical and Dynamical Properties of Covariant Lyapunov Vectors in a Coupled Atmosphere-Ocean Model - Multiscale Effects, Geometric Degeneracy, and Error Dynamics

description: We study a simplified coupled atmosphere-ocean model using the formalism of covariant Lyapunov vectors (CLVs), which link physically-based directions of perturbations to growth/decay rates. The model is obtained via a severe truncation of quasi-geostrophic equations for the two fluids, and includes a simple yet physically meaningful representation of their dynamical/thermodynamical coupling. The model has 36 degrees of freedom, and the parameters are chosen so that a chaotic behaviour is observed. One finds two positive Lyapunov exponents (LEs), sixteen negative LEs, and eighteen near-zero LEs. The presence of many near-zero LEs results from the vast time-scale separation between the characteristic time scales of the two fluids, and leads to nontrivial error growth properties in the tangent space spanned by the corresponding CLVs, which are geometrically very degenerate. Such CLVs correspond to two different classes of ocean/atmosphere coupled modes. The tangent space spanned by the CLVs corresponding to the positive and negative LEs has, instead, a non-pathological behaviour, and one can construct robust large deviations laws for the finite time LEs, thus providing a universal model for assessing predictability on long to ultra-long scales along such directions. It is somewhat surprising to find that the tangent space of the unstable manifold has strong projection on both atmospheric and oceanic components. Our results underline the difficulties in using hyperbolicity as a conceptual framework for multiscale chaotic dynamical systems, whereas the framework of partial hyperbolicity seems better suited, possibly indicating an alternative definition for the chaotic hypothesis. Our results suggest the need for accurate analysis of error dynamics on different time scales and domains and for a careful set-up of assimilation schemes when looking at coupled atmosphere-ocean models.

Greece and the Limits of European Solidarity
Creators: name: Morgan, Glyn
Publisher: name: Phenomenology and Mind
Year: 2015

description: This paper examines some recent arguments put forward by economists and philosophers that purport to show that Europeans owe Greece some form of solidarity. The paper distinguishes two different firms of solidarity: justice-based solidarity and remedial solidarity. It argues that Europeans -- working through their institutions -- owe the Greeks only remedial solidarity, but only insofar as they actually harmed the Greeks through imposing upon them a dysfunctional monetary union, an exploitative bailout program, or a damaging form of austerity.

The Joined Destiny of Migration and European Citizenship
Creators: name: Urbinati, Nadia
Publisher: name: Phenomenology and Mind
Year: 2015

description: In this paper I try to unpack the nest of issues that recent waves of migrations bring to the floor and show how immigration plays a crucial role in the making or unmaking democratic citizenship in post-national Europe. Although recurrent terrorist attacks make harder and harder for many opinion-makers and ordinary citizens to associate immigration with positive opportunity for European citizenship, the paper argues that the right to free movement and of emigration is embedded in the nucleus of principles and ideals that makes for European citizenship since the Treaty of Rome. Subsequently, the paper introduces the category of statelessness and uses it to tackle the problem of the legal and political evolution furthered by the practice of rights within the horizon that is defined by the ideal of a European post-national citizenship. Refugees and immigrants are interpreted as a challenge and an opportunity in the spirit of Hannah Arendt’s intuition that citizenship brings to the floor an unsolvable paradox between the human and the political. The conclusion of the paper argues that stateless people—the migrants—personify this paradox as they can be the locus of a new political practice that signals an incipient form of citizenship, truly disconnected from the nation as the European citizenship aspires to be. The denial of many civil and political rights to undocumented immigrants and the detention of thousands of migrants in the camps located at the peripheries of Europe contrast radically with the community of rights that Europe has sought to be since its inception.

La gouvernance, ou du Fédéralisme post-national des pouvoirs exécutifs

description: This text corresponds to a presentation at the «Forum européen des alternatives», held in Paris on May 30-31, 2015. It focuses on the substitution – even at a linguistic level – of a “government” (as a legitimate expression of a democratically represented European citizenship) with a “governance” (the actual decision organism on issues related to economy and the crisis) constituted by the “Troika” (composed by representatives of the European Commission, the Central Bank and the International Monetary Fund). It shows how and in which (large) measure this “post-national Federalism of the executive powers” (Habermas) thwarts the rules of political representation stated by the Treatise of Lisbon and violates the European Charter of Rights.

La Secolarità o Europa
Creators: name: Bruni, Marco
Publisher: name: Phenomenology and Mind
Year: 2015

description: The author asserts the identity between Europe and secularization. Secularization not only as a process of unchristianizing and laicization, but especially in the meaning of term given by Karl Löwith, or as immanentizing of eschaton. In this sense the roots of Europe are certainly christian, but their results are anti-christian: “Secularity or Europe” as the title of the essay means. In fact the secularization coincides with the technological self-affirmation of the modern man (Blumenberg). Today, however, the technical means seem able to emancipate from their human creator (Severino), inaugurating a scenery that oscillates between heaven of the technique and planetary destruction.

description: The essay develops the suggestion by Federico Chabod that Machiavelli is the father of the modern idea of Europe. Starting from the analysis of the thought of Machiavelli, it shows the structurally plural soul of Europe, as it has historically evolved and as it was understood by some of its principal actors. The figure that best describes the essence of European integration is the archipelago, and the unity which coexists with the multiplicity of its component parts.

Year: 2015

description: This essay examines the economic and political conditions and the balance of power in today’s European Union. It does this by using some of the categories of Antonio Gramsci’s ‘Prison Notebooks’, in particular the concept of ‘southern question’, the ‘passive revolution’ and the ‘Caesarism’. The aim is to criticize the ‘European system’ trough a perspective that, recalling Gramsci, gives emphasis on labor Issues and ‘subordinates’.

The Idea of Europe between Utopia and Rootedness. A European Canon for the Education of a New Generation of Citizens
Creators: name: Poncina, Carla
Publisher: name: Phenomenology and Mind
Year: 2015

description: Historically, Europe has always dealt with its problems through the use of terminology and the Greco-Roman classical model. Such was the case of not only the Italian humanists that created a new world through the renaissance of antiquity but also the philosophers of the enlightenement whose ideas sprouted from the basic model of the classics, consequently resulting in the fall of the ancien régime. This tradition of humanism and universalism was once again used in the 20th century by the founding fathers of a New Europe post the Second World War. Today this very idea of Europe has been put into question. As a result, there is the necessity to rethink a New European Canon that could serve as a starting point for a New Humanism of which education could constitute as an essential vehicle.

Stoves or sugar? Willingness to adopt improved cookstoves in Malawi

name: Jagger, Pamela
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: Malawi has set a target of adoption of two million improved cookstoves (ICS) by 2020. Meeting this objective requires knowledge about determinants of adoption, particularly in rural areas where the cost of traditional cooking technologies and fuels are non-monetary, and where people have limited capacity to purchase an ICS. We conducted a discrete choice experiment with 383 households in rural Malawi asking them if they would chose a locally made ICS or a package of sugar and salt of roughly equal value. Six months later, we assessed adoption and stove use patterns. Sixty-six percent of households chose the ICS. We find that having a larger share of crop residues in household fuel supply, awareness of the environmental impacts of woodfuel reliance, time the primary cook devotes to collecting fuelwood, and peer effects at the village-level increase the odds of choosing the ICS. Having a large labor supply for fuelwood collection and experience with a non-traditional cooking technology decreased the odds of choosing the ICS. In a rapid assessment six months after stoves were distributed, we found 80% of households were still using the ICS, but not exclusively. Our findings suggest considerable potential for wide-scale adoption of ICS in Malawi.

description: This is a review of the books on the European Union by two well-known Italian economists, Luigi Zingales and Giacomo Vaciago. It turns out there is a broad area of agreement and complementarity between them. Their treatments are summarized under the following ten headings: 1) The political genesis of the European Union; 2) the surprisingly narrow range of activities included in the present economic and monetary union; 3) the dubious validity of the “theory of forward reactions”, that should guarantee the forward direction of the unification process; 4) The unsure presuppositions of the Maastricht Treaty, and the reasons why it arose the skepticism of most American economists; 5) the Italian crisis and the European paralysis; 6) Italy stands to Europe as Southern Italy to Italy; 7) Italexit? 8) What brakes the progress of the unification process? 9) What corrections to existing institutions? 10) Is there still a role for a European Federation?

description: Lipkin-Meshkov-Glick model of two anisotropically interacting spins in a magnetic field is proposed as a working substance of a quantum Otto engine to explore and exploit the anisotropy effects for the optimization of engine operation. Three different cases for the adiabatic branches of the cycle have been considered. In the first two cases, either the magnetic field or coupling strength are changed; while in the third case, both the magnetic field and the coupling strength are changed by the same ratio. The system parameters for which the engine can operate similar to or dramatically different from the engines of non-interacting spins or of coupled spins with Ising model or isotropic XY model interactions are determined. In particular, the role of anisotropy to enhance cooperative work, and to optimize maximum work with high efficiency, as well as to operate the engine near the Carnot bound are revealed.

Hydrodynamic Theories for Flows of Active Liquid Crystals and the Generalized Onsager Principle

description: We articulate and apply the generalized Onsager principle to derive transport equations for active liquid crystals in a fixed domain as well as in a free surface domain adjacent to a passive fluid matrix. The Onsager principle ensures fundamental variational structure of the models as well as dissipative properties of the passive component in the models, irrespective of the choice of scale (kinetic to continuum) and of the physical potentials. Many popular models for passive and active liquid crystals in a fixed domain subject to consistent boundary conditions at solid walls, as well as active liquid crystals in a free surface domain with consistent transport equations along the free boundaries, can be systematically derived from the generalized Onsager principle. The dynamical boundary conditions are shown to reduce to the static boundary conditions for passive liquid crystals used previously.

description: This review regards a document, known as the Tractatus pacis toti Christianitati fiendae (1462-1464), drawn up on the initiative of George of Bohemia, the Hussite King. The document proposes the creation of an organization meant to guarantee peace all over the cristianitas and coordinate the war against the Turks. Particularly remarkable is the negligible role given to the Pope and the Emperor in favour of the magnates of the main European naciones, whose sovereignty power is nevertheless limited by the “international” unio envisaged.

description: Identifying the relevant geography is an ongoing obstacle to effectively evaluate the influence of neighborhood built environment on physical activity. We characterized density and diversity of destinations that 77 older adults experienced within individually representative GPS activity spaces and traditional residential buffers and assessed their associations with accelerometry-measured physical activity. Traditional residential buffers had lower destination density and diversity than activity spaces. Activity spaces based only on pedestrian and bicycling trips had higher destination densities than all-mode activity spaces. Regardless of neighborhood definition, adjusted associations between destinations and physical activity generally failed to reach statistical significance. However, within pedestrian and bicycling-based activity spaces each additional destination type was associated with 243.3 more steps/day (95% confidence interval (CI) 36.0, 450.7). Traditional buffers may not accurately portray the geographic space or neighborhood resources experienced by older adults. Pedestrian and bicycling activity spaces elucidate the importance of destinations for facilitating active transportation.

description: Galaxy merging is widely accepted to be a key driving factor in galaxy formation and evolution, while the feedback from AGN is thought to regulate the BH-bulge coevolution and the star formation process. In this context, we focused on 1SXPSJ050819.8+172149, a local (z=0.0175) Seyfert 1.9 galaxy (L_bol~4x10^43 ergs/s). The source belongs to an IR-luminous interacting pair of galaxies, characterized by a luminosity for the whole system (due to the combination of star formation and accretion) of log(L_IR/L_sun)=11.2. We present the first detailed description of the 0.3-10keV spectrum of 1SXPSJ050819.8+172149, monitored by Swift with 9 pointings performed in less than 1 month. The X-ray emission of 1SXPSJ050819.8+172149 is analysed by combining all the Swift pointings, for a total of ~72ks XRT net exposure. The averaged Swift-BAT spectrum from the 70-month survey is also analysed. The slope of the continuum is ~1.8, with an intrinsic column density NH~2.4x10^22 cm-2, and a deabsorbed luminosity L(2-10keV)~4x10^42 ergs/s. Our observations provide a tentative (2.1sigma) detection of a blue-shifted FeXXVI absorption line (rest-frame E~7.8 keV), suggesting the discovery for a new candidate powerful wind in this source. The physical properties of the outflow cannot be firmly assessed, due to the low statistics of the spectrum and to the observed energy of the line, too close to the higher boundary of the Swift-XRT bandpass. However, our analysis suggests that, if the detection is confirmed, the line could be associated with a high-velocity (vout~0.1c) outflow most likely launched within 80r_S. To our knowledge this is the first detection of a previously unknown ultrafast wind with Swift. The high NH suggested by the observed equivalent width of the line (EW~ -230eV, although with large uncertainties), would imply a kinetic output strong enough to be comparable to the AGN bolometric luminosity.

Spatio-temporal dimensions of child poverty in America, 1990–2010

Year: 2016

description: The persistence of childhood poverty in the United States, a wealthy and developed country, continues to pose both an analytical dilemma and public policy challenge, despite many decades of research and remedial policy implementation. In this paper, our goals are twofold, though our primary focus is methodological. We attempt both to examine the relationship between space, time, and previously established factors correlated with childhood poverty at the county level in the continental United States as well as to provide an empirical case study to demonstrate an underutilized methodological approach. We analyze a spatially consistent dataset built from the 1990 and 2000 U.S. Censuses, and the 2006–2010 American Community Survey. Our analytic approach includes cross-sectional spatial models to estimate the reproduction of poverty for each of the reference years as well as a fixed effects panel data model, to analyze change in child poverty over time. In addition, we estimate a full space-time interaction model, which adjusts for spatial and temporal variation in these data. These models reinforce our understanding of the strong regional persistence of childhood poverty in the U.S. over time and suggest that the factors impacting childhood poverty remain much the same today as they have in past decades.

The development and implementation of continuous flow procedures for photochemical transformations

Subjects: Other chemical sciences not elsewhere classified

description: Photochemistry, the employment of light as traceless reagent, has been utilised in organic synthesis for decades. It allows access to complex, highly functionalised molecules from simple starting substrates that would be otherwise inaccessible by classical thermal means. However, the synthetic method had drawbacks in that it is notoriously inefficient leading to low product yields and long reaction times. Microfluidic technology or ‘continuous flow’ gives an answer to these problems whilst offering extra advantages such as enhanced reaction safety, simpler reaction set up and the ability to carry out multistep syntheses without excess user handling. Presented here is a thorough investigation into the advantages and drawbacks of continuous flow, in the synthesis of both cyclobutane-based and furan-based molecules. Chapter 2 reports the first application of a continuous flow procedure in the well-established dimerization of N-vinylcarbazole (NVC). The procedure was fully optimised using a Design of Experiments (DoE) approach with varying factors including flow rate, lamp wavelength and catalyst loading. This reaction was scaled from 1 mmol to 10 mmol with no additional complications and minimal impact on the yield. The newly development continuous flow procedure was then applied to the synthesis of lignan-based cyclobutanes including the natural products magnosalin and pellucidin A, as well as a brief exploration into the dimerization of cyclic enamines. Chapter 3 further expands on the continuous flow dimerization procedure and reports the synthesis of novel bromocarbazole-based cyclobutanes. The commercially available bromocarbazoles were vinylated using an Ir-catalysed method and subjected to dimerization in both batch and continuous flow. This allowed for a comparison of the two procedures showing that the continuous flow synthesis had reduced reaction times, increased yields and an overall simpler reaction set up. The continuous flow procedure was also expanded to several other vinylcarbazoles with pre-installed functionalities such as hydroxyl, vinylethers and tert-butyl groups. Post-modification of the cyclobutanes was performed through Pd-catalysed Suzuki coupling and borylation reactions. Chapter 4 develops on previous work reported by the Kimber group into the synthesis of furan containing molecules. The two-step synthetic procedure was fully transferred from batch into a continuous flow set up. By telescoping the photooxidation step and Appel-type dehydration negating the use of pure O2 and the need to isolate the peroxide intermediate. Both the batch and continuous flow procedures were then applied to the synthesis of 2,5-diaryl furan motifs with functionalities including halogens, alkyls and trifluoromethyls. Post-modification allowed for the molecules to be installed with further boryl and aryl groups.

description: With the consideration of photon recycling effect, the efficiency limit of methylammonium lead iodide (CH3NH3PbI3) perovskite solar cells is predicted by a detailed balance model. To obtain convincing predictions, both AM 1.5 spectrum of Sun and experimentally measured complex refractive index of perovskite material are employed in the detailed balance model. The roles of light trapping and angular restriction in improving the maximal output power of thin-film perovskite solar cells are also clarified. The efficiency limit of perovskite cells (without the angular restriction) is about 31%, which approaches to Shockley-Queisser limit (33%) achievable by gallium arsenide (GaAs) cells. Moreover, the Shockley-Queisser limit could be reached with a 200 nm-thick perovskite solar cell, through integrating a wavelength-dependent angular-restriction design with a textured light-trapping structure. Additionally, the influence of the trap-assisted nonradiative recombination on the device efficiency is investigated. The work is fundamentally important to high-performance perovskite photovoltaics.

These Calabi-Yau threefolds give rise to five dimensional quiver gauge theories and are dual to configurations of M5-M2-branes. We determine the Gopakumar-Vafa invariants for these threefolds and show that the genus $g$ free energy is given by the weight $2g$ Eisenstein series. We also show that although the free energy at all genera are modular invariant the full partition function satisfies the non-perturbative modular transformation property discussed by Lockhart and Vafa in arXiv:1210.5909 and therefore the modularity of free energy is up to non-perturbative corrections.

description: Early life exposure to endocrine disrupting chemicals may alter adipogenesis and energy balance leading to changes in obesity risk. Several studies have evaluated the association of prenatal bisphenol A exposure with childhood body size but only one study of male infants has examined other environmental phenols. Therefore, we assessed associations between prenatal exposure to environmental phenols and fat mass in a prospective birth cohort. We quantified four phenol biomarkers in third trimester maternal spot urine samples in a cohort of women enrolled in New York City between 1998 and 2002 and evaluated fat mass in their children using a Tanita scale between ages 4 and 9 years (173 children with 351 total observations). We estimated associations of standard deviation differences in natural log creatinine-standardized phenol biomarker concentrations with percent fat mass using linear mixed effects regression models. We did not observe associations of bisphenol A or triclosan with childhood percent fat mass. In unadjusted models, maternal urinary concentrations of 2,5-dichlorophenol were associated with greater percent fat mass and benzophenone-3 was associated with lower percent fat mass among children. After adjustment, phenol biomarkers were not associated with percent fat mass. However, the association between benzophenone-3 and percent fat mass was modified by child’s sex: benzophenone-3 concentrations were inversely associated with percent fat mass in girls (beta = −1.51, 95% CI = −3.06, 0.01) but not boys (beta = −0.20, 95% CI = −1.69, 1.26). Although we did not observe strong evidence that prenatal environmental phenols exposures influence the development of childhood adiposity, the potential antiadipogenic effect of benzophenone-3 in girls may warrant further investigation.

description: The Majorana representation for spin operators enables efficient application of field-theoretical methods for the analysis of spin dynamics. Moreover, a wide class of spin correlation functions can be reduced to Majorana correlations of the same order, simplifying their calculation. For the spin-boson model, direct application of this method in the lowest order allows for a straightforward computation of the transverse-spin correlations, however, for the longitudinal-spin correlations it apparently fails in the long-time limit. Here we indicate the reason and discuss, how this method can be used as a convenient and accurate tool for generic spin correlations. Specifically, we demonstrate that accurate results are obtained by avoiding the use of the longitudinal Majorana fermion, and that correlations of the remaining transverse Majorana fermions can be easily evaluated using an effective Gaussian action.

description: Organophosphate compounds are commonly used in residential furniture, electronics, and baby products as flame retardants and are also used in other consumer products as plasticizers. Although the levels of exposure biomarkers are generally higher among children and decrease with age, relatively little is known about the individual characteristics associated with higher levels of exposure. Here, we investigate urinary metabolites of several organophosphate flame retardants (PFRs) in a cohort of pregnant women to evaluate patterns of exposure.

description: This is a registration of an analysis plan within the longitudinal study Early Autism Seden (EASE; www.projektsmasyskon.se). The plan is registered after data collection, but prior to processing and analysis of the data. We aim to study how early factors of formal language (receptive vocabulary and sentence understanding) and social communication abilities (early gesture use, play, object actions, pretend-play and imitation), are associated with decontextualized language use at 24 months of age. We also aim to investigate associations between decontextualized language use and ASD likelihood and traits.
CpG and methylation-dependent DNA binding and dynamics of the methylcytosine binding domain 2 protein at the single-molecule level

description: The methylcytosine-binding domain 2 (MBD2) protein recruits the nucleosome remodeling and deacetylase complex (NuRD) to methylated DNA to modify chromatin and regulate transcription. Importantly, MBD2 functions within CpG islands that contain 100s to 1000s of potential binding sites. Since NuRD physically rearranges nucleosomes, the dynamic mobility of this complex is directly related to function. In these studies, we use NMR and single-molecule atomic force microscopy and fluorescence imaging to study DNA binding dynamics of MBD2. Single-molecule fluorescence tracking on DNA tightropes containing regions with CpG-rich and CpG-free regions reveals that MBD2 carries out unbiased 1D diffusion on CpG-rich DNA but subdiffusion on CpG-free DNA. In contrast, the protein stably and statically binds to methylated CpG (mCpG) regions. The intrinsically disordered region (IDR) on MBD2 both reduces exchange between mCpG sites along the DNA as well as the dissociation from DNA, acting like an anchor that restricts the dynamic mobility of the MBD domain. Unexpectedly, MBD2 binding to methylated CpGs induces DNA bending that is augmented by the IDR region of the protein. These results suggest that MBD2 targets NuRD to unmethylated or methylated CpG islands where its distinct dynamic binding modes help maintain open or closed chromatin, respectively.

description: The demand for natural pigments for industrial applications has significantly increased. Penicillium brevicompactum was recently reported as a promising pigments producer using submerged fermentation and a synthetic culture medium containing lactose. In this work, pigment production by P. brevicompactum was studied under different fermentation conditions, namely, submerged fermentation with free (SmF) and immobilized mycelium (SmFi), and solid-state fermentation (SSF). The potential of culture media composed of agro-industrial byproducts (cheese-whey (CW) and corn steep liquor (CSL)) was investigated for the first time as low-cost alternatives to pigment production by P. brevicompactum. The fungus showed great adaptability to the different culture media and types of fermentation, being able to synthesize pigments under all the tested conditions. A culture medium composed of 34.6 g/L of CW and 8 g/L of CSL proved to be the most suitable alternative to the synthetic medium, especially under SmF and SmFi. Our data also show that different mixtures of pigments (yellow, orange, and red) can be produced depending on the medium composition and the type of fermentation. Additionally, the immobilization and reuse of biomass to produce pigments by P. brevicompactum were demonstrated for the first time, suggesting the possibility of operating under repeated batch mode at an industrial scale.
