description: We study the percolation and jamming of rods ($k$-mers) on a square lattice that contains defects. The point defects are placed randomly and uniformly on the substrate before deposition of the rods. The general case of unequal probabilities for orientation of depositing of rods along different directions of the lattice is analyzed. Two different models of deposition are used. In the relaxation random sequential adsorption model (RRSA), the deposition of rods is distributed over different sites on the substrate. In the single cluster relaxation model (RSC), the single cluster grows by the random accumulation of rods on the boundary of the cluster. For both models, a suppression of growth of the infinite cluster at some critical concentration of defects $d_c$ is observed. In the zero defect lattices, the jamming concentration $p_j$ (RRSA) and the density of single clusters $p_s$ (RSC) decrease with increasing length rods and with a decrease in the order parameter. For the RRSA model, the value of $d_c$ decreases for short rods as the value of $s$ increases. For longer rods, the value of $d_c$ is almost independent of $s$. Moreover, for short rods, the percolation threshold is almost insensitive to the defect concentration for all values of $s$. For the RSC model, the growth of clusters with ellipse-like shapes is observed for non-zero values of $s$. The density of the clusters $p_s$ at the critical concentration of defects $d_c$ depends in a complex manner on the values of $s$ and $k$. For disordered systems, the value of $p_s$ tends towards zero in the limits of the very long rods and very small critical concentrations $d_c \to 0$. In this case, the introduction of defects results in a suppression of rods stacking and in the formation of `empty' or loose clusters with very low density. On the other hand, denser clusters are formed for ordered systems.

Globally symmetric topological phase: from anyonic symmetry to twist defect

description: Topological phases in two dimensions support anyonic quasiparticle excitations that obey neither bosonic nor fermionic statistics. These anyon structures often carry global symmetries that relate distinct anyons with similar fusion and statistical properties. Anyonic symmetries associate topological defects or fluxes in topological phases. As the symmetries are global and static, these extrinsic defects are semiclassical objects that behave disparately from conventional quantum anyons. Remarkably, even when the topological states supporting them are Abelian, they are generically non-Abelian and powerful enough for topological quantum computation. In this article, I review the most recent theoretical developments on symmetries and defects in topological phases.

description: The pygmy dipole resonance and photon strength functions (PSF) in stable and unstable Ni and Sn isotopes are calculated within the microscopic self-consistent version of the extended theory of finite fermi systems in the quasiparticle time blocking approximation. The approach includes phonon coupling (PC) effects in addition to the standard QRPA approach. The Skyrme force SLy4 is used. A pygmy dipole resonance in 72Ni is predicted at the mean energy of 12.4 MeV exhausting 25.7% of the total energy-weighted sum rule. With our microscopic E1 PSFs in the EMPIRE 3.1 code, the following radiative nuclear reaction characteristics have been calculated for several stable and unstable even-even Sn and Ni isotopes: 1) neutron capture cross sections, 2) corresponding neutron capture gamma-spectra, 3) average radiative widths of neutron resonances. Here, three variants of the microscopic nuclear level density models have been used and a comparison with the phenomenological generalized superfluid model (GSM) has been performed. In all the considered properties, including the recent experimental data for PSF in Sn isotopes, the PC contributions turned out to be significant, as compared with the QRPA one, and necessary to explain the available experimental data. The phenomenological GSM NLD model used in EMPIRE3.1 gives, on the whole, the worse results than the microscopic HFB plus combinatorial NLD model.

description: We apply methods of the so-called `inverse problem of the calculus of variations' to the stabilization of an equilibrium of a class of two-dimensional controlled mechanical systems. The class is general enough to include, among others, the inverted pendulum on a cart and the inertia wheel pendulum. By making use of a condition that follows from Douglas' classification, we derive feedback controls for which the control system is variational. We then use the energy of a suitable controlled Lagrangian to provide a stability criterion for the equilibrium.
Jerome's role in the transmission of the correspondence between Seneca and Paul
Creators: name: Molina, Pablo Alberto
Publisher: name: University of North Carolina at Chapel Hill
Year: 2011

description: In this thesis I examine Jerome's role in the transmission of the correspondence between Seneca and Paul. Jerome was the first to mention the letters in De Viris Illustribus (DVI) in 393 C.E. The notice on Seneca in DVI greatly contributed to the survival and transmission of the moralist's correspondence. I argue that: (1) contrary to what many scholars have postulated, Jerome actually saw the forged correspondence in its entirety and was not fooled by it (which can be demonstrated by a detailed analysis of authorship issues in DVI). (2) Jerome found the forgery useful because it enabled him to co-opt Seneca as a pagan author capable of advancing his views on marriage in his treatise Adversus Iovinianum - written shortly after DVI - in which he copiously borrowed from Seneca's De Matrimonio.

description: Small-scale systems and integrated concepts are currently being explored by researchers to promote widespread application of solar cooling technologies in buildings. Chapter 7 presented a qualitative evaluation of these technologies in terms of their potential for façade integration. Moreover, this chapter expands the assessment of application possibilities by exploring the feasibility of solar cooling integrated façades, as decentralised self-sufficient cooling modules, on different warm climate contexts. The climate feasibility of solar electric and solar thermal concepts is evaluated based on solar availability and local cooling demands to be met by current technical possibilities. Numerical calculations are employed for the evaluation, considering statistical climate data; cooling demands per orientation from scenarios simulated in Chapter 6; and state-of-the-art efficiency values as reference for current performance limits of solar cooling technologies, from Chapter 7. Main results show that in general, warm-dry climates and east/west orientations are more suited for solar cooling façade applications. Results from the base scenario show promising potential for solar thermal technologies, reaching a theoretical solar fraction of 100% in several cases. Application possibilities expand when higher solar array area and lower tilt angle on panels are considered, but these imply aesthetical and constructional constraints for façade design. Finally, recommendations are drafted considering prospects for the exploration of suitable technologies for each location, and façade design considerations for the optimisation of the solar input per orientation.

description: Increasing cooling demands in buildings call for innovative environmentally friendly systems to cope with remaining loads after the application of passive design strategies. Solar cooling technologies present interesting assets, but their application in the built environment remains greatly limited. Hence, this chapter seeks to assess their potential for widespread application, identifying possibilities and current bottlenecks for the architectural integration of solar cooling technologies in façades. The assessment is based on a state-of-the-art review and discussion of key attributes for façade integration of selected technologies; and a qualitative evaluation of their suitability to respond to main product related barriers for the integration of building services identified in Chapter 4. An overview of the cooling principles behind the operation of the assessed technologies was presented in Chapter 3, so this chapter focuses exclusively on key aspects to overcome barriers related to the technical feasibility, physical integration, durability, performance, and aesthetics of future integrated concepts. Results show that the suitability of the assessed technologies varies according to each particular barrier. Hence, no technology currently fits all required aspects. Nonetheless, the use of thermoelectric modules and compact units based on absorption technologies are regarded as the most promising for the development of either integral building components, or modular plug & play systems for façade integration. In any case, this is heavily conditioned to further efforts and explorations in the field to overcome identified challenges and knowledge gaps.

Vegan artist: exploring the ethical use of animals in contemporary art through a reconsideration of the vegan philosophy
Creators: name: Coleman (Student), Ellie
Publisher: name: University of Southern Queensland
Year: 2021
Subjects: animal ethics, visual art, creative arts, veganism, contemporary art, animal rights

description: In response to the limited discourses on vegan practices in art, this practice-led study explores the ethical dilemma for vegan artists who intentionally use animals in their art practice in order to reconsider hierarchal human-animal relationships. The study explores the scope of ethical issues for vegan artists as a way of reconsidering the vegan philosophy to accommodate the use of animals in art as a form of activism (Baker 2013). That is, the very use of animals in a vegan artist’s practice can be a tacit means of critically engaging in animal ethics (Singer 2018). Through this approach, not only will the research directly impact vegan artists, but will also emphasise the role of ethical treatment of animals and the broader social implications of such treatment (Cancian 1993). Central to this research is my own positioning as a vegan artist who uses ethically sourced animals in my practice as a method to create understanding of human-animal relationships in response to human-animal power imbalances (Wrenn 2015). These power imbalances are underpinned by the evolutionary models within the field of natural sciences, such as Aristotle’s ‘Scala Naturae’ (Deane-Drummond 2019), which I argue have greatly influenced contemporary thinking on human-animal relationships (Rigato & Minelli 2013). Deploying a practice-led methodology via my developed Vegan Artist Cyclic Web Inquiry, this research results in sculptural installations that expand on the understanding of ethical uses of animals in contemporary art (Sullivan 2005). I draw on other contemporary artists such as Australian Julia deVille, British/New Zealand-based Angela Singer and British Krysten Newby who employ animals in their practice to address human-animal relationships, yet do not reconsider veganism in the way this research does (Johnson 2014). My practice comprises 70% weighting of the doctoral study and employs a ritualised process-driven approach involving collecting, recycling and creating artwork from animal remains to stimulate a personal and broader critical agency through modelling alternative non-hierarchal human animal relationships. The exegesis, comprising 30% weighting, provides theoretical discussions on the use of animals in art to reconsider the vegan philosophy. In turn, the overall study contributes to the discourses of contemporary art, vegan philosophy and animal ethics by including ethically sourced animals as alternative materials in art practice.
Counterinsurgency in Iraq: Examining the Different Frames of the Media, and the Role of Information Operations During the Surge

description: In a counterinsurgency environment, Information Operations play a crucial role. The insurgents and terrorists in Iraq rely on shaping narrative through media events and propaganda, and these narratives allow them to convince key publics to support their cause, as well as change the political support landscape as events unfold. If the U.S. allows these narratives to stand uncontested, then the insurgency controls information dominance. This thesis examined the frames present in articles, and the public support from the U.S. perspective, from the summer of 2007 through the summer of 2008. Additionally, recommendations for an Information Operations campaign moving forward in Iraq are made, using role theory and framing theory as a basis.

description: Recruiting student-athletes for intercollegiate athletics has become competitive at the highest level. The University of North Carolina at Chapel Hill strives to be successful in all of its athletic programs. The purpose of this study is to discover what is important to non-revenue sports student-athletes at this university as they make their institutional decision. Understanding the importance placed on certain factors can improve the ability of the athletic programs at UNC-Chapel Hill to have continued success. This study attempts to build on the recent growing research in this field. In doing so, it identified academic reputation as the most important factor. Due to contrasting results from analysis of variance, no clear declaration can be made about significant statistical differences. However, slight differences were found among certain athletic grant-in-aid levels, as well as between residents and non-residents for some component groups.

description: Cooling demands of commercial buildings present a relevant challenge for a sustainable future. They account for over half of the overall energy needs for the operation of an average office building in warm climates, and this situation is expected to become more pressing due to increasing temperatures in cities worldwide. To tackle this issue, it is widely agreed that the application of passive strategies should be the first step in the design of energy efficient buildings, only using active equipment if it is truly necessary. Nonetheless, there is still further need for information regarding the potential limits derived from their application. This chapter explores the impact of selected passive cooling strategies in commercial buildings from warm climates, discussing their effectiveness in multiple scenarios and climate contexts. This task is carried out through the statistical analysis of results from documented research experiences, to define overall ranges and boundary conditions; and through software simulation of selected parameters to isolate their impact under a controlled experimental setup. General findings show that the mere inclusion of passive strategies is not enough to guarantee relevant savings. Their effectiveness is conditioned to both the harshness of a given climate and an adequate application of the strategies. Specific recommendations are discussed for the passive strategies considered in the evaluation, in order to optimise the overall performance of a given building in different climates.

description: Epithelial ovarian cancer has been researched to be the most common and an aggressive form of cancer. Owing to its ability to evade detection until stage 3, when the cancer has metastasized extensively, it is important and crucial to find an effective treatment. Keeping this concept in mind, we implemented in silico analyses in the form of molecular docking and dynamics. The gene CDK1, the encoder of the protein that is a member if the Ser/Thr protein kinase family, is a catalytic subunit of the M-phase promoting factor (MPF), and a key player in the eukaryotic cell cycle. The protein encoded by CDK1 was chosen as a target for molecular docking, due to its existence as a significant hub gene from literature reviews. The ligands chosen were imipramine, trazodone, propafenone, resveratrol, alpha estradiol, levonorgestrel, apigenine, doxazosin, rottlerin, nortriptyline, prochlorprazine, noretynodrel, chlomipramine, fluphenazine, amiodarone, medrysone, piperlongumine, daunorubicin, vironostat, methotrexate and scriptaid, based on their potential evaluated by drug databases. The active sites of the protein were analysed using PDBSUM, and their neighboring amino acids were evaluated. The amino acids were observed to be Tyrosine 15A, Glutamine 81, Isoleucine 10A and Leucine 83A. The grid was calculated based on the coordinates of isoleucine, glutamine and tyrosine residues. Grid formation was done based on this location of the active site, and molecular docking was carried out using AutoDock Vina. The highest docking score observed was the protein against Doxazosin, showing a binding affinity of -10.4 kcal/mol. The interactions within the complex were observed using ProteinsPlus and Discovery Studio, and the interactions seen were among The results will be analysed and the best docked complexes were chosen to carry out molecular dynamics simulations using DESMOND.
Improving traffic flow at a 2-to-1 lane reduction with wirelessly connected, adaptive cruise control vehicles

description: Wirelessly connected vehicles that exchange information about traffic conditions can reduce delays caused by congestion. At a 2-to-1 lane reduction, the improvement in flow past a bottleneck due to traffic with a random mixture of 40% connected vehicles is found to be 52%. Control is based on connected-vehicle-reported velocities near the bottleneck. In response to indications of congestion the connected vehicles, which are also adaptive cruise control vehicles, reduce their speed in slowdown regions. Early lane changes of manually driven vehicles from the terminated lane to the continuous lane are induced by the slowing connected vehicles. Self-organized congestion at the bottleneck is thus delayed or eliminated, depending upon the incoming flow magnitude. For the large majority of vehicles, travel times past the bottleneck are substantially reduced. Control is responsible for delaying the onset of congestion as the incoming flow increases. Adaptive cruise control increases the flow out of the congested state at the bottleneck. The nature of the congested state, when it occurs, appears to be similar under a variety of conditions. Typically 80-100 vehicles are approximately equally distributed between the lanes in the 500-m region prior to the end of the terminated lane. Without the adaptive cruise control capability, connected vehicles can delay the onset of congestion but do not increase the asymptotic flow past the bottleneck. Calculations are done using the Kerner-Klenov stochastic discrete-time model for manual vehicles. The dynamics of the connected vehicles is given by a conventional adaptive cruise control algorithm plus commanded deceleration. Because time in the model for manual vehicles is discrete (one-second intervals), it is assumed that the acceleration of any vehicle immediately in front of a connected vehicle is constant during the time interval.

description: Solar energy has been actively promoted as a clean energy source for a long time; however, solar technologies have not been widely used in the built environment, mostly limiting their operation to industrial and macroscale applications. Along with commercially available products such as building integrated PV panels (BIPV) or building integrated solar thermal collectors (BIST); novel solar cooling integrated facades are seen as interesting alternatives for the development of new active façade components for high-performing commercial buildings. Nevertheless, there are barriers to overcome to push for widespread application of architecturally integrated solar façades. This chapter identifies perceived barriers for widespread façade integration of solar technologies, to explore the current scenario and generate guidelines for future developments. To achieve this, the chapter discusses the results of the second part of the survey presented in the previous chapter, which addresses the perceived potential and specific issues for the integration of solar technologies. General results point to economic aspects as the main barrier to overcome, followed by particular issues related to current limitations of components and architectural products. In this aspect, most mentions point to performance, aesthetics and technical complexity of current systems as issues to improve in order to promote the development of solar integrated architectural products.

description: Gartenarbeit und die Beobachtung von Tieren ermöglicht sowohl Studierenden, als auch Schülerinnen und Schülern eine direkte und unmittelbare Erfahrung mit der Natur. Diese Naturerfahrungen sind auch ein wichtiges Element im Bereich der Bildung für nachhaltige Entwicklung (BNE) und dem Klimaschutz. Umweltfreundliches Verhalten wird z.B. durch den Aufenthalt in der Natur positiv beeinflusst (Richardson et al. 2020). Die direkte Auseinandersetzung mit der Natur kann zudem den Lernenden die Möglichkeit bieten die Bedeutung dieser Themen zu erfahren. Laut der Symboltheorie Cassirers (1965) und deren Weiterentwicklung durch Ulrich Gebhard (2020) werden aus bloßen Naturkontakten immer dann Erfahrungen, wenn ein Bedeutungszusammenhang zwischen dem Gegenstand und den Lernenden entsteht und das Gegenüber zu einem Symbol für diesen Zusammenhang werden kann. Basierend auf diesem theoretischen Konzept galt es zu überprüfen, inwiefern Studierende in ihren Hochschulgärten symbolische Naturerfahrungen machen. Die als Go-Along-Interview geführten Gespräche zeigten durch die qualitative Inhaltsanalyse, dass Hochschulgärten eine Vielzahl an Symbolisierungsanlässen bieten und diese von Studierenden auch wahrgenommen werden. Oft stand hierbei „Anschauungsmaterial“ des Schulgartens, wie einzelne Pflanzen oder Beete, als Symbol für Erinnerungen an diese Elemente im Wirklichkeitszusammenhang der Lebenswelt der Studierenden.

description: The integration of decentralised building services into façade components presents advantages from functional and constructional standpoints. However, this integrated approach has not been massively implemented, having only stand-alone buildings and façade concepts as examples.This chapter delves into the requirements for integration within the façade development process, aiming to identify the main perceived problems for building services integration in facades at design, production and assembly stages. The employed method was an exploratory survey addressed to professionals involved in the development of façade systems for office buildings, at different stages, in order to generate new knowledge based on practical experience. The survey was conducted from mid-September to mid-November, 2015 and was distributed both as an online form and in printed format among several professional networks. Results show that the main problems refer to the overall process, particularly regarding coordination issues among different disciplines and stakeholders, while other problems such as costs and lack of knowledge, while still relevant, have more impact on particular stages. Among relevant problems related to the products themselves, the results show physical integration issues during production and assembly stages, and barriers derived from unreliable performance and technical limitations of current products to be integrated in façade systems.

description: We formulated the $Lambda(1405)$ (abbreviated as $Lambda^*$) $rightarrow (Sigmapi)^0$ invariant-mass spectra produced in the $K^- + p rightarrow Sigma^+ (1660) + pi^-$, followed by $Sigma^+ (1660) rightarrow Lambda(1405) + pi^+ rightarrow Sigmapi + pi^+$, processes at $p(K^-) = 4.2$ GeV/$c$, in which both the incident channel for a quasi-bound $K^-p$ state and its decay process to $(Sigma pi)^0$ were taken into account realistically. We calculated $M(Sigma pi)$ spectral shapes using mixed transition matrices, $T_{21} = T_{ Sigmapi leftarrow K^-p}$ and $T_{22} = T_{ Sigma pi leftarrow Sigma pi}$, for various theoretical models involving $Lambda^*$. The asymmetric spectra were compared to old experimental data of Hemingway, and it was found that the mixing of the two channels, written as $(1-f) , T_{21} + f, T_{22}$, gave a better result than considering the individual channels, yielding $f = 0.376_{-0.019}^{+0.021}$, $M(Lambda^*) = 1406.6_{-3.3}^{+3.4}$ MeV/$c^2$ and $Gamma = 70 pm 2$ MeV, nearly consistent with the 2014 PDG values.

description: In this contribution the hypothesis that the Galactic globular clusters with substantial internal [Fe/H] abundance ranges are the former nuclei of disrupted dwarf galaxies is discussed. Evidence considered includes the form of the metallicity distribution function, the occurrence of large diffuse outer envelopes in cluster density profiles, and the presence of ([s-process/Fe], [Fe/H]) correlations. The hypothesis is shown to be plausible but with the caveat that if significantly more than the current nine clusters known to have [Fe/H] spreads are found, then re-evaluation will be required.

description: Solar cooling systems have gained increased attention these last years, for their potential to lower indoor temperatures using renewable energy. However, architectural integration of these systems in buildings has not been fully explored. Current developments such as small scale solar driven heat pumps and solar cooling kits commercially available for application raise questions about how to successfully integrate these systems into buildings, while present interesting opportunities for the development of new performance based façade components or even self-sustaining cooling façade modules for high-performing commercial buildings. So, what are the conceptual issues and state-of-the-art components and systems to consider for solar cooling façade integration? This chapter discusses current possibilities for façade integration of solar cooling systems, generating a framework for the understanding and further development of solar cooling façade systems. The proposed framework was made by means of a review of solar cooling technologies and solar cooling façade concepts reported by several researchers. The outcomes of the chapter are a matrix outlining the possibilities for the integration of several components and subsystems from the entire cooling process (cooling generation, distribution and delivery), and an early assessment of the development level of state-of-the-art experiences within the field considering examples from current research projects and working prototypes, for the development of solar cooling integrated façade concepts.

description: We study the role of systematic effects in observational studies of the cusp-core problem under the minimum disc approximation using a suite of high-resolution (25-pc softening length) hydrodynamical simulations of dwarf galaxies. We mimic realistic kinematic observations and fit the mock rotation curves with two analytic models commonly used to differentiate cores from cusps in the dark matter distribution. We find that the cored pseudo-isothermal sphere (ISO) model is strongly favoured by the reduced $χ^2_ν$ of the fits in spite of the fact that our simulations contain cuspy Navarro-Frenk-White profiles (NFW). We show that even idealized measurements of the gas circular motions can lead to the incorrect answer if velocity underestimates induced by pressure support, with a typical size of order $\sim$5 km s$^{-1}$ in the central kiloparsec, are neglected. Increasing the spatial resolution of the mock observations leads to more misleading results because the inner region, where the effect of pressure support is most significant, is better sampled. Fits to observations with a spatial resolution of 100 pc (2 arcsec at 10 Mpc) favour the ISO model in 78-90 per cent of the cases, while at 800-pc resolution, 40-78 per cent of the galaxies indicate the fictitious presence of a dark matter core. The coefficients of our best-fit models agree well with those reported in observational studies; therefore, we conclude that NFW haloes can not be ruled out reliably from this type of analysis.

description: In a review article, Hegarty, Burte, and Boone observe that the relationship between sense of direction and spatial strategies is currently neither well understood nor exist any self-report measures which assess both aspects simultaneously. This study contributes to this discussion by proposing and testing a bifactor model for the German language scale on spatial strategies (German: Fragebogen räumliche Strategien), which was proposed by Münzer and Hölscher in 2011. We base our analysis on a representative sample of the German population (N = 4280) and an own dataset (N = 459). In addition to the specific factors representing the spatial strategies egocentric, allocentric and cardinal directions - all of which were analyzed by Münzer and Hölscher in their initial article on the scale - the bifactor model we propose involves sense of direction as a general factor. We provide evidence that the bifactor model shows a better goodness-of-fit than the three-factor correlational model involving the specific factors only. We also provide several indices checking the dimensional nature of the general and the specific factors. Our results support the fact that both aspects of self -estimated spatial abilities are measured using the questionnaire. In einem Review stellen Hegarty, Burte und Boone fest, dass der Zusammenhang zwischen Orientierungssinn und räumlichen Strategien derzeit weder gut verstanden ist, noch gibt es Fragebögen, die beide Aspekte gleichzeitig erfassen. Wir prüfen ein bifaktorielles Modell für den Fragebogen räumliche Strategien (Münzer & Hölscher, 2011) mit dem Ziel, die hoch korrelierten Faktoren „Orientierung global/egozentrisch“, „Überblick“ und „Himmelsrichtung“ zu spezifizieren und mithilfe eines globalen Faktors „Orientierungssinn“ die gemeinsame Varianz zu klären. Wir stützen unsere Analyse auf eine repräsentative Stichprobe der deutschen Bevölkerung (N = 4280) und einen eigenen Datensatz (N = 459). Das bifaktorielle Modell zeigt in beiden Stichproben einen besseren Modellfit als das dreifaktorielle Korrelationsmodell, wobei die Parameter beider Modelle auch Messinvarianz aufweisen. Wir überprüfen zudem mehrere Indizes, die die dimensionalen Eigenschaften des globalen und der spezifischen Faktoren überprüfen. Unsere Ergebnisse unterstützen die Interpretation, dass beide Aspekte selbsteingeschätzter räumlicher Fähigkeiten mit dem Fragebogen gemessen werden können.

description: When a fluid is confined to a nanopore, its thermodynamic properties differ from the properties of a bulk fluid, so measuring such properties of the confined fluid can provide information about the pore sizes. Here we report a simple relation between the pore size and isothermal compressibility of argon confined in these pores. Compressibility is calculated from the fluctuations of the number of particles in the grand canonical ensemble using two different simulation techniques: conventional grand-canonical Monte Carlo and grand-canonical ensemble transition-matrix Monte Carlo. Our results provide a theoretical framework for extracting the information on the pore sizes of fluid-saturated samples by measuring the compressibility from ultrasonic experiments.

Small-scale magnetic and velocity inhomogeneities in a sunspot light bridge

description: High resolution spectro-polarimetric observations of a sunspot light bridge by Hinode, reveal small-scale inhomogeneities in the magnetic field and velocity. These inhomogeneities arise as a consequence of a weak, secondary lobe in the Stokes V profile which have a polarity opposite that of the sunspot and very large (>5 km/s) Doppler velocities of both signs, suggesting two distinct types of magnetic anomalies. These two sets of inhomogeneities are highly time-dependent and appear exclusively in the upper half of the light bridge and only after the light bridge is completely formed. Both sets of inhomogeneities appear as patches and can be present independent of the other, next to one another, or spatially separated in a single scan. A two-component inversion of the corresponding spectral profiles indicate that the inhomogeneities occupy a very small fraction, amounting to less than 10 %, of the resolution element. These structures are likely driven by small-scale magneto-convection where they could further interact with the overlying sunspot magnetic field to produce reconnection jets in the chromosphere.

Research overview of cooling in office buildings
Creators: name: Prieto Hoces, Alejandro Ignacio
Publisher: name: A+BE | Architecture and the Built Environment

description: This chapter serves as a general introduction to the topics explored throughout the dissertation, presenting a panorama of the available knowledge on façade related cooling strategies in office buildings. This was carried out by categorising and discussing reported research experiences from the past 25 years in order to identify knowledge gaps and define current paths and trends for further exploration. Peer reviewed journal articles were selected as the source for the study, given the reliability of the information published under peer-review processes. Several queries were carried out throughout online journal article databases, considering published papers from 1990 onwards. The resulting article database was then explored through descriptive analysis and in-depth review of some articles to expand on specific topics in order to thoroughly visualise scientific interest and tendencies within the field of study for the last 25 years. Results show the high current relevance of cooling research, having experienced an increase of publications under different climate contexts and varied topics ranging from passive to solar cooling, which is seen as a research field on its own. Also, in terms of research methods, software simulations seem to be the primary tool for cooling research, which makes sense for performance driven developments. On the other hand, the main knowledge gaps identified are the need for specific research regarding possibilities for application and architectural integration of cooling systems; the lack of articles addressing some specific cooling strategies, such as the use of evaporative and ground cooling; and the need for more information about the operation of cooling systems, especially taking users’ perception and their behaviour into account.

The potential of the Eurozone crisis to mobilize extreme right support in Spain, Portugal, and Italy

description: Since the 1980's, Europe has experienced a resurgence in the extreme right. In this paper, attention will be directed on the successes and failures of the extreme right in Spain, Portugal, and Italy. Additionally, this paper will analyze whether the current Eurozone crisis has benefitted the extreme right in these countries, as it has done in Greece. However, it will be argued that the benefits of the Eurozone crisis for the extreme right have been limited to increased media attention and less on electoral success. This is evidenced by the vast array of news articles contributing to the idea that the extreme right is strengthening in light of the Eurozone crisis; yet the extreme right has experienced limited electoral success in Spain and Portugal due to its inability to shed its fascist links, and the extreme right has had decreased electoral success in Italy's recent elections.

description: The FAIR principles refer frequently to metadata as a key enabler in discoverability, but also having a major role in accessibility and reusability. Publishing structured metadata on the web can provide a simple and efficient means to increase the FAIRness of research resources: it exposes metadata contained in web pages through a formal mechanism, allowing systematic collection and processing by web-based crawlers. Efforts to adopt structured metadata within and across domains would benefit greatly from a set of recommendations that would help ensure consistent implementation leading to enhanced discoverability and accessibility of data. Based on community consultation and subsequent work, this guidelines provides nine recommendations to support the process of publishing structured metadata on the web, namely: Recommendation 1: Clarify the purpose(s) of your markup Recommendation 2: Identify what resource are to be marked up with structured data Recommendation 3: Adopt or develop a crosswalk from a repository schema to markup vocabulary Recommendation 4: Incorporate external vocabulary if it helps to improve data discoverability and interoperability Recommendation 5: Implement markup syntax consistently by following community practices Recommendation 6: Be friendly to web crawlers Recommendation 7: Make the best use of available tools for mapping, generating and validating structured data Recommendation 8: Document and share every step Recommendation 9: Find and join a community, and follow their established practices
