description: Polarimetry is about to become a powerful tool for determining the atmospheric properties of exoplanets. To provide the basis for the interpretation of observational results and for predictive studies to guide future observations, sophisticated analysis tools are required. Our goal is to develop a radiative transfer tool that contains all the relevant continuum polarization mechanisms for the comprehensive analysis of the polarized flux resulting from the scattering in the atmosphere of, on the surface of, and in the local planetary environment (e.g., planetary rings, exomoons) of extra-solar planets. Furthermore, our goal is to avoid common simplifications such as locally plane-parallel planetary atmospheres, the missing cross-talk between latitudinal and longitudinal regions, or the assumption of either a point-like star or plane-parallel illumination. As a platform for the newly developed numerical algorithms, we use the 3D Monte Carlo radiative transfer code POLARIS. The code is extended and optimized for the radiative transfer in exoplanetary atmospheres. We investigate the reflected flux and its degree of polarization for different phase angles for a homogeneous cloud-free atmosphere and an inhomogeneous cloudy atmosphere. To take advantage of the 3D radiative transfer and to demonstrate the potential of the code, the impact of an additional circumplanetary ring on the reflected polarized flux is studied. The presence of a circumplanetary ring consisting of small water-ice particles has a noticeable impact on the reflected polarized radiation. In particular, the reflected flux strongly increases at larger phase angles if the planetary orbit is seen edge-on because the considered particles tend to scatter forwards. In contrast, the degree of polarization decreases at these phase angles.

Controversial Embodiment: Sport, Masculinity, Dis/Ability

Subjects: complex embodiment; disability; sport culture; performance; cyborg; Pistorius

description: This essay is an attempt at investigating visible forms of complex, indeed controversial embodiment, with the specific intention of concentrating on the ways they interrogate delicate issues such as disability, masculinity and prosthetic sport performance. I intend to sound the shifting boundaries between dis-ability and super-ability as manifested in iconic figures such as Stelarc and, in other fields, Oscar Pistorius, whose unsteady position as privileged/disabled bladerunner seems to require – and indeed to gather – particularly intense scrutiny. I shall introduce a few contemporary discourses on corporeality and embodiment, which focus on the ‘troubling’ nature of auxiliary organs Freud refers to in the much contended paragraph I adopt as epigraph and guiding procedural light; I shall move from Butler and Giddens to Jean-Luc Nancy’s work on transplants and/as prostheses to include theoretical debates on disintegrating embodiment and disability studies, in order to proceed towards an analysis of the short-circuiting of allegedly secure practices of (masculine) embodiment in sport culture and theory.

description: As Eric Hobsbawm has highligted, “immagined community of millions often seems more real as a team of eleven players […] The individual, even the one who only cheers, becomes a symbol of his nation himself””. That is why many national goverments have used sport as a tool for nation building. There is one political actor, however, which would appear not to have drawn any advantage from the symbolic power of sport: the European Union. By referring to the literature on the subjetct and some archival research, the author seek to pin down the reasons behind this distance between sport and the idea of Europe, calling for the creation of an European team in different sporting disciplines in the future that may make up for this lack of common European action.

Considerations on gravitational waves in higher-order local and non-local gravity

description: The detection of gravitational wave modes and polarizations could constitute an extremely important signature to discriminate among different theories of gravity. According to this statement, it is possible to prove that higher-order non-local gravity has formally the same gravitational spectrum of higher-order local gravity. In particular, we consider the cases of $f \left( R, \Box R, \Box^2 R, \cdots, \Box^n R \right) = R + \sum_{i=1}^n α_i R \Box^i R$ gravity, linear with respect to both $R$ and $\Box^i R$ and $ f \left( R, \Box R \right) = R + α\left(\Box R\right)^2 $ gravity, quadratic with respect to $\Box R$, where it is demonstrated the graviton amplitude changes if compared with General Relativity. We also obtain the gravitational spectrum of higher-order non-local gravity $ f \left( R, \Box^{-1} R, \Box^{-2} R, \cdots, \Box^{-n} R \right) = R + \sum_{i=1}^n α_i R \Box^{-i} R$. In this case, we have three state of polarization and $n+3$ oscillation modes. More in detail, it is possible to derive two transverse tensor $(+)$ and $(\times)$ standard polarization modes of frequency $ω_{1}$, massless and with 2-helicity; $n+1$ further scalar modes of frequency $ω_{2},\dots,ω_{n+2}$, massive and with 0-helicity, each of which has the same mixed polarization, partly longitudinal and partly transverse.

Sports, Global Politics, and Social Value Change: A Research Agenda

Year: 2015
Subjects: conflict, cosmopolitanism, global sports, globalization, international politics, social identity, value change

description: Despite their important role in forging, constructing and self-ascribing social identities and shaping popular culture, sports have long been a marginalized subject of social science inquiry, cultural studies, and research on international politics. Only in recent years this has begun to change. The article seeks to advance the still nascent but emerging cross-disciplinary field of research on sports and global politics in two ways: first, by addressing largely unexplored issues of sports, politics, and social conflicts, putting the spotlight on sociopolitical arenas beyond commercialized sports mega events, which have attracted most scholarly attention in contemporary research; and second, by generating hypotheses on the indirect political effects of sports cultures, in particular on the relationship between local social identities—reinforced through sports—and cosmopolitan value change. These interlinked spatial and substantive claims ground a new critical research framework and agenda: it examines sports as profoundly embedded in socioeconomic, cultural and political forms of rule and domination but also seeks to disclose sports’ emancipatory and subversive potential in advancing globalization from below.

Cotunneling through two-level quantum dots weakly coupled to ferromagnetic leads

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)
subject: FOS: Physical sciences

description: The spin-polarized transport through two-level quantum dots weakly coupled to ferromagnetic leads is considered theoretically in the Coulomb blockade regime. It is assumed that the dot is doubly occupied, so that the current flows due to cotunneling through singlet and triplet states of the dot. It is shown that transport characteristics strongly depend on the ground state of quantum dot. If the ground state is a singlet, differential conductance ($G$) displays a broad minimum at low bias voltage, while tunnel magnetoresistance (TMR) is given by the Julliere value. If triplet is the ground state of the system, there is a maximum in differential conductance at zero bias when the leads are magnetized in antiparallel. The maximum is accompanied by a minimum in TMR. The different behavior of $G$ and TMR may thus help to determine the ground state of the dot and the energy difference between the singlet and triplet states.

description: The study examined participatory leadership and rural transformation in four selected States in the Niger Delta region.  The main objective of the study is to examine how participatory leadership can bring about rural transformation in four selected States in the Niger Delta region. Three research questions were formulated in line with the objectives. The study employed a survey research method, using quantitative and qualitative designs for the collection of data and analysis. Eight thousand (8,000) respondents from the sixteen (16) selected local government areas in Bayelsa State, Rivers State, Delta State, and Akwa Ibom State as the sample size. Structured questionnaires were distributed to the eight thousand (8,000) respondents; however, seven thousand nine hundred and eighty (7,980) copies were retrieved for data analysis. Four-point Likert scale for structured research questionnaires using arithmetic mean for data analysis. The findings revealed that lack of social amenities for the development of the rural areas; lack of modern health facilities in the rural areas thereby increasing the high rate of mortality amongst others are the challenges facing rural transformation in the Niger Delta region. In this light, the research work recommended amongst others that government and non-governmental organization should provide infrastructural development in the rural areas; this will increase employment, youth empowerment, and self-reliance amongst the people that will cushion rural-urban migration and youth restiveness. Rural community development should be based on a bottom-top approach that would give rural dwellers through their community to identify and present their felt needs to the government and non-governmental organization before the execution of any project for sustainability

description: We have carried out observations of CCH ($N=1-0$), CH$_{3}$CN ($J=5-4$), and three $^{13}$C isotopologues of HC$_{3}$N ($J=10-9$) toward three massive young stellar objects (MYSOs), G12.89+0.49, G16.86--2.16, and G28.28--0.36, with the Nobeyama 45-m radio telescope. Combined with previous results on HC$_{5}$N, the column density ratios of $N$(CCH)/$N$(HC$_{5}$N), hereafter the CCH/HC$_{5}$N ratios, in the MYSOs are derived to be $\sim 15$. This value is lower than that in a low-mass warm carbon chain chemistry (WCCC) source by more than one order of magnitude. We compare the observed CCH/HC$_{5}$N ratios with hot-core model calculations (Taniguchi et al. 2019). The observed ratios in the MYSOs can be best reproduced by models when the gas temperature is $\sim 85$ K, which is higher than in L1527, a low-mass WCCC source ($\sim 35$ K). These results suggest that carbon-chain molecules detected around the MYSOs exist at least partially in higher temperature regions than those in low-mass WCCC sources. There is no significant difference in column density among the three $^{13}$C isotopologues of HC$_{3}$N in G12.89+0.49 and G16.86-2.16, while HCC$^{13}$CN is more abundant than the others in G28.28--0.36. We discuss carbon-chain chemistry around the three MYSOs based on the CCH/HC$_{5}$N ratio and the $^{13}$C isotopic fractionation of HC$_{3}$N.

description: To investigate the origin of cooperative behaviors, we developed an evolutionary model of sequential strategies and tested our model with computer simulations. The sequential strategies represented by stochastic machines were evaluated through games of Iterated Prisoner's Dilemma (IPD) with other agents in the population, allowing co-evolution to occur. We expanded upon past works by proposing a novel mechanism to mutate stochastic Moore machines that enables a richer class of machines to be evolved. These machines were then subjected to various selection mechanisms and the resulting evolved strategies were analyzed. We found that cooperation can indeed emerge spontaneously in evolving populations playing iterated PD, specifically in the form of trigger strategies. In addition, we found that the resulting populations converged to evolutionarily stable states and were resilient towards mutation. In order to test the generalizability of our proposed mutation mechanism and simulation approach, we also evolved the machines to play other games such as Chicken, Stag Hunt, and Battle, and obtained strategies that perform as well as mixed strategies in Nash Equilibrium.

description: We report on a scheme for the creation of time-bin entangled states out of two subsequent single photons. Both photons arrive on the same input port of a beamsplitter and the situation in which the photons leave the beamsplitter on different output ports is post-selected. We derive a full quantum mechanical analysis of such time-bin entanglement for emitters subject to uncorrelated dephasing processes and apply this model to sequential single photons emerging from a single semiconductor quantum dot. Our results indicate that the visibility of entanglement is degraded by decoherence effects in the quantum dot, but can be restored by use of CQED effects, namely the Purcell effect.

description: The magnetoelastic coupling in Ca$_{1.8}$Sr$_{0.2}$RuO$_4$ and in Ca$_{1.5}$Sr$_{0.5}$RuO$_4$ has been studied combining high-resolution dilatometer and diffraction techniques. Both compounds exhibit strong anomalies in the thermal-expansion coefficient at zero and at high magnetic field as well as an exceptionally large magnetostriction. All these structural effects, which are strongest in Ca$_{1.8}$Sr$_{0.2}$RuO$_4$, point to a redistribution of electrons between the different $t_{2g}$ orbitals tuned by temperature and magnetic field. The temperature and the field dependence of the thermal-expansion anomalies in Ca$_{1.8}$Sr$_{0.2}$RuO$_4$ yield evidence for a critical end-point lying close to the low-temperature metamagnetic transition; however, the expected scaling relations are not well fulfilled.

description: An increasing interaction between man and machine in all areas of society leads not only to new job proﬁles but also initiates a discussion about the needed digital competencies in the future. The European Commission's Joint Research Centre has developed in a multi-stakeholder approach an initial framework to describe and measure the needed competencies such as problem solving ability, capacity of teamwork and programming skills (Carretero et al. 2017). It is expected that the transfer of technical, occupation-oriented and personality-building competencies alongside subject-related knowledge will become increasingly important in higher education (Association of Sponsors of German Science 2016, pp. 26-27). In order to avoid inequalities among students -those with and without so-called digital competencies - new learning approaches are needed. One possible approach towards the enhancement of digital competencies can be found within the maker movement.
A Comparison of Inquiry-Based Conceptual Feedback vs. Traditional Detailed Feedback Mechanisms in Software Testing Education: An Empirical Investigation

description: The feedback provided by current testing education tools about the deficiencies in a student's test suite either mimics industry code coverage tools or lists specific instructor test cases that are missing from the student's test suite. While useful in some sense, these types of feedback are akin to revealing the solution to the problem, which can inadvertently encourage students to pursue a trial-and-error approach to testing, rather than using a more systematic approach that encourages learning. In addition to not teaching students why their test suite is inadequate, this type of feedback may motivate students to become dependent on the feedback rather than thinking for themselves. To address this deficiency, there is an opportunity to investigate alternative feedback mechanisms that include a positive reinforcement of testing concepts. We argue that using an inquiry-based learning approach is better than simply providing the answers. To facilitate this type of learning, we present Testing Tutor, a web-based assignment submission platform that supports different levels of testing pedagogy via a customizable feedback engine. We evaluated the impact of the different types of feedback through an empirical study in two sophomore-level courses. We use Testing Tutor to provide students with different types of feedback, either traditional detailed code coverage feedback or inquiry-based learning conceptual feedback, and compare the effects. The results show that students that receive conceptual feedback had higher code coverage (by different measures), fewer redundant test cases, and higher programming grades than the students who receive traditional code coverage feedback.

description: We report on a numerical study of quantum transport in disordered two dimensional graphene and graphene nanoribbons. By using the Kubo and the Landauer approaches, transport length scales in the diffusive (mean free path, charge mobilities) and localized regimes (localization lengths) are computed, assuming a short range disorder (Anderson-type). In agreement with localization scaling theory, the electronic systems are found to undergo a conventional Anderson localization in the zero temperature limit. Localization lengths in weakly disordered ribbons are found to differ by two orders of magnitude depending on their edge symmetry, but always remain several orders of magnitude smaller than those computed for 2D graphene for the same disorder strength. This pinpoints the role of transport dimensionality and edge effects.

description: We discuss the definition of quantum probability in the context of "timeless" general--relativistic quantum mechanics. In particular, we study the probability of sequences of events, or multi-event probability. In conventional quantum mechanics this can be obtained by means of the ``wave function collapse" algorithm. We first point out certain difficulties of some natural definitions of multi-event probability, including the conditional probability widely considered in the literature. We then observe that multi-event probability can be reduced to single-event probability, by taking into account the quantum nature of the measuring apparatus. In fact, by exploiting the von-Neumann freedom of moving the quantum classical boundary, one can always trade a sequence of non-commuting quantum measurements at different times, with an ensemble of simultaneous commuting measurements on the joint system+apparatus system. This observation permits a formulation of quantum theory based only on single-event probability, where the results of the "wave function collapse" algorithm can nevertheless be recovered. The discussion bears also on the nature of the quantum collapse.

REEEM-D4.3a_Policy Brief - The Role of Behaviour and Heterogeneity for the Adoption of Technologies
Creators: name: REEEM Project
Publisher: name: Zenodo
Year: 2019

description: Models built for strategic European energy policy assessments often make compromises in terms of how they represent human behaviour and decision making, which is a design choice that is usually forced on model designers by a lack of data availability on consumer preferences. As a result, it is often difficult for energy models to depict uptake levels and technology diffusion rates for new consumer technologies in households that are in line with real world observations. As part of the REEEM project, a multinational research team from the UK, Finland and Croatia took steps to address this critical shortcoming in energy models by carrying out detailed surveys on 3000 European households in their respective countries, and using these to build databases of attitudes, preferences, and lifestyles. Discrete choice modelling, a technique used to understand which factors drive decision making, was used to identify the critical determinants of consumer purchases in domestic heating and privately owned vehicles. It was found that costs are usually an influential factor when it comes to technology choice, but also that there are a range of other considerations that exert a powerful influence on decision making. In particular, consumers appear to strongly prefer technologies with which they are familiar and have already purchased previously, suggesting that preferences are extremely “sticky”. For European climate policy, this means that while it might be initially very difficult to implement a changeover from high carbon to low carbon technologies, once the switch has already taken place these become the “new normal”, and consumers may unlikely to regress to older systems. The wide variety of non-cost factors that were found to influence decisions might also suggest alternative avenues for policymakers to explore when seeking to create momentum towards systemic change.

description: The Cygnus region, which dominates the local spiral arm of the Galaxy, is one of the nearest complexes of massive star formation. Its massive stellar content, regions of ongoing star formation, and molecular gas have been studied in detail. However, little is known of the history of the region beyond the past 10 Myr. The brightness and spectroscopic characteristics of red supergiants make it easy to identify them and build up a virtually complete sample of such stars at the distance of the Cygnus region, thus providing a record of massive star formation extending several tens of Myr into the past, a period inaccessible through the O and early B stars observable at present. We have made a selection of a sample of bright, red stars in an area of 84 square degrees covering the whole present extension of the Cygnus region. We have obtained spectroscopy in the red visible range allowing an accurate, homogeneous spectral classification as well as a reliable separation between supergiants and other cool stars. Our data are complemented with Gaia Data Release 2 astrometric data. We have identified 29 red supergiants in the area, 17 of which had not been previously classified as supergiants. Twenty-four of the 29 most likely belong to the Cygnus region and four of the remaining to the Perseus arm. We have used their derived luminosities and masses to infer the star formation history of the region. Intense massive star formation activity is found to have started approximately 15 Myr ago, and we find evidence for two other episodes, one taking place between 20 and 30 Myr ago and another one having ended approximately 40 Myr ago. There are small but significant differences between the kinematic properties of red supergiants younger or older then 20 Myr, hinting that stars of the older group were formed outside the precursor of the present Cygnus complex, possibly in the Sagittarius-Carina arm.

Response, relaxation and transport in unconventional superconductors

description: We investigate the collision-limited electronic Raman response and the attenuation of ultrasound in spin-singlet d-wave superconductors at low temperatures. The dominating elastic collisions are treated within a t-matrix approximation, which combines the description of weak (Born) and strong (unitary) impurity scattering. In the long wavelength limit a two-fluid description of both response and transport emerges. Collisions are here seen to exclusively dominate the relaxational dynamics of the (Bogoliubov) quasiparticle system and the analysis allows for a clear connection of response and transport phenomena. When applied to quasi-2-d superconductors like the cuprates, it turns out that the transport parameter associated with the Raman scattering intensity for B1g and B2g photon polarization is closely related to the corresponding components of the shear viscosity tensor, which dominates the attenuation of ultrasound. At low temperatures we present analytic solutions of the transport equations, resulting in a non-power-law behavior of the transport parameters on temperature.

Improved bounds on entropy production in living systems

description: Living systems maintain or increase local order by working against the Second Law of Thermodynamics. Thermodynamic consistency is restored as they dissipate heat, thereby increasing the net entropy of their environment. Recently introduced estimators for the entropy production rate have provided major insights into the thermal efficiency of important cellular processes. In experiments, however, many degrees of freedom typically remain hidden to the observer, and in these cases, existing methods are not optimal. Here, by reformulating the problem within an optimization framework, we are able to infer improved bounds on the rate of entropy production from partial measurements of biological systems. Our approach yields provably optimal estimates given certain measurable transition statistics. In particular, it can reveal non-zero heat production rates even when non-equilibrium processes appear time symmetric and so may pretend to obey detailed balance. We demonstrate the broad applicability of this framework by providing improved bounds on the entropy production rate in a diverse range of biological systems including bacterial flagella motors, growing microtubules, and calcium oscillations within human embryonic kidney cells.

Sequentially Triggered Star Formation in OB Associations

description: We discuss observational evidence for sequential and triggered star formation in OB associations. We first review the star formation process in the Scorpius-Centaurus OB association, the nearest OB association to the Sun, where several recent extensive studies have allowed us to reconstruct the star formation history in a rather detailed way. We then compare the observational results with those obtained for other OB associations and with recent models of rapid cloud and star formation in the turbulent interstellar medium. We conclude that the formation of whole OB subgroups (each consisting of several thousand stars) requires large-scale triggering mechanisms such as shocks from expanding wind and supernova driven superbubbles surrounding older subgroups. Other triggering mechanisms, like radiatively driven implosion of globules, also operate, but seem to be secondary processes, forming only small stellar groups rather than whole OB subgroups with thousands of stars.

description: Financial econometrics has become an increasingly popular research field. In this paper we review a few parametric and nonparametric models and methods used in this area. After introducing several widely used continuous-time and discrete-time models, we study in detail dependence structures of discrete samples, including Markovian property, hidden Markovian structure, contaminated observations, and random samples. We then discuss several popular parametric and nonparametric estimation methods. To avoid model mis-specification, model validation plays a key role in financial modeling. We discuss several model validation techniques, including pseudo-likelihood ratio test, nonparametric curve regression based test, residuals based test, generalized likelihood ratio test, simultaneous confidence band construction, and density based test. Finally, we briefly touch on tools for studying large sample properties.

description: We present analyses of near-infrared, spectroscopic data from the Apache Point Observatory Galactic Evolution Experiment (APOGEE) survey for 45 previously confirmed or candidate white dwarf-main sequence (WDMS) binaries identified by the optical SDSS and LAMOST surveys. Among these 45 systems, we classify three as having red giant primaries in the LAMOST sample and fourteen to be young stellar object contaminants in the photometrically identified SDSS sample. From among the subsample of 28 systems that we confirm to have MS primaries, we derive and place limits on orbital periods and velocity amplitudes for fourteen. Seven systems have significant velocity variations that warrant a post-common-envelope (PCE) binary classification -- four of which are newly classified, three of which are newly confirmed, and five for which we can derive full orbital parameters. If confirmed, one of these newly discovered systems (2M14544500+4626456) will have the second longest orbital period reported for a typical, compact PCE WDMS binary ($P=15.1$ days). In addition to the seven above, we also recover and characterize with APOGEE data the well known PCE WDMS systems EG UMa and HZ 9. We also investigate the overall metallicity distribution of the WDMS sample, which is a parameter space not often explored for these systems. Of note, we find one system (2M14244053+4929580) to be extremely metal-poor (${\rm [Fe/H]}=-1.42$) relative to the rest of the near-solar sample. Additionally, the PCE systems in our sample are found to be, on average, higher in metallicity than their wide-binary counterparts, though we caution that with this small number of systems, the sample may not be representative of the overall distribution of WDMS systems.
