kernel misorientation

description: In order to effectively measure sub-structural deformation patterns that are generated during plastic deformation, the implications of spatial and angular resolution limitations of EBSD must be considered. The angular resolution is affected by the EBSD system and acquisition parameters, and therefore, it is important for deformation analysis to quantify the angular resolution of the datasets.

Methodology for estimating the angular measurement noise for EBSD datasets was developed by Masayuki Kamaya at the Institute of Nuclear Technology, Japan. His work is published in: https://doi.org/10.1016/j.ultramic.2011.02.004. Kamaya proposed the extended local misorientation -concept for quantifying the accuracy of the measurements and for studying local misorientation gradients.

This code is an implementation of Kamaya's method for Matlab/MTEX.The initial release only works for data on a square grid, and gives an estimate of the (global) angular measurement noise. Note that the measurement procedure should only be applied to raw data, values given to de-noised data are not representative.

description: Monolayer graphene exhibits exceptional electronic and mechanical properties, making it a very promising material for nanoelectromechanical (NEMS) devices. Here, we conclusively demonstrate the piezoresistive effect in graphene in a nano-electromechanical membrane configuration that provides direct electrical readout of pressure to strain transduction. This makes it highly relevant for an important class of nano-electromechanical system (NEMS) transducers. This demonstration is consistent with our simulations and previously reported gauge factors and simulation values. The membrane in our experiment acts as a strain gauge independent of crystallographic orientation and allows for aggressive size scalability. When compared with conventional pressure sensors, the sensors have orders of magnitude higher sensitivity per unit area.

Quantifying hierarchical mixture quality in polymer composite materials: structure and inhomogeneity in multiple scales

Year: 2012
Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: Mixture quality plays a crucial role in the physical properties of multi-component immiscible polymer mixtures including nanocomposites and polymer blends. Such complex mixtures are often characterized by hierarchical internal structures, which have not been accounted for by conventional mixture quantifications. We propose a way to characterize the mixture quality of complex mixtures with hierarchical structures. Starting from a concentration field, which can be typically obtained from TEM/SEM images, the distribution of the coarsegrained concentration is analyzed to obtain the scale-dependent inhomogeneity of a mixture. The hierarchical nature of a mixture is characterized by multiple characteristic scales of the scale-dependent inhomogeneity. We demonstrate how the proposed method works to characterize sizes and distributions in different dispersions. This method is generally applicable to various complex mixtures.

Search for a Higgs boson in diphoton final states with the D0 detector in 9.6 fb-1 of p-pbar collisions at sqrt(s)=1.96 TeV

description: We present a search for a Higgs boson decaying into a pair of photons based on 9.6 fb-1 of p-pbar collisions at sqrt(s)=1.96 TeV collected with the D0 detector at the Fermilab Tevatron Collider. The search employs multivariate techniques to discriminate signal from the non-resonant background and is separately optimized for a standard model and a fermiophobic Higgs boson. No significant excess of data above the background prediction is observed and upper limits on the product of the cross section and branching fraction are derived at the 95% confidence level as a function of Higgs boson mass. For a standard model Higgs boson with mass of 125 GeV, the observed (expected) upper limits are a factor of 12.8 (8.7) above the standard model prediction. The existence of a fermiophobic Higgs boson with mass in the 100-113 GeV range is excluded at the 95% confidence level.

description: Widespread vaccination in pursuit of herd immunity has been recognized as the most promising approach to ending the global pandemic of coronavirus disease 19 (COVID-19). The vaccination of children and adolescents has been extensively debated and the first COVID-19 vaccine is now approved in European countries for children aged > 12 years of age. Our study investigates vaccination hesitancy in a cohort of German secondary school students. We assessed 903 students between age 9 and 20 in the period between 17 May 2021 and 30 June 2021. 68.3% (n = 617) reported intention to undergo COVID-19 vaccination, while 7% (n = 62) did not want to receive the vaccine and 15% (n = 135) were not yet certain. Age and parental level of education influenced COVID-19 vaccine hesitancy. Children under the age of 16 as well as students whose parents had lower education levels showed significantly higher vaccine hesitancy. Conclusion: Identifying subsets with higher vaccination hesitancy is important for targeting public information campaigns in support of immunization.What is Known:• The willingness to receive COVID-19 vaccination among adults in Europe is about 70%, but data for children and adolescents is lacking.• The lack of immunization in younger cohorts represents a significant barrier to achieving herd immunity, and also leaves children and adolescents vulnerable to acute and long-term morbidity from natural COVID-19 infections.What is New:• Intention-to-vaccinate among children and adolescents is high (~ 70%); conversely, vaccination hesitancy is low.• Age and parental level of education influenced COVID-19 vaccine hesitancy among children and adolescents. © 2021, The Author(s).

description: Modern ecology has re-emphasized the need for a quantitative understanding of the original 'survival of the fittest theme' based on analyzis of the intricate trade-offs between competing evolutionary strategies that characterize the evolution of life. This is key to the understanding of species coexistence and ecosystem diversity under the omnipresent constraint of limited resources. In this work we propose an agent based model replicating a community of interacting individuals, e.g. plants in a forest, where all are competing for the same finite amount of resources and each competitor is characterized by a specific growth-reproduction strategy. We show that such an evolution dynamics drives the system towards a stationary state characterized by an emergent optimal strategy, which in turn depends on the amount of available resources the ecosystem can rely on. We find that the share of resources used by individuals is power-law distributed with an exponent directly related to the optimal strategy. The model can be further generalized to devise optimal strategies in social and economical interacting systems dynamics.

Data quality, experimental artifacts, and the reactivity of the psychological subject matter

description: While the term “reactivity” has come to be associated with specific phenomena in the social sciences, having to do with subjects’ awareness of being studied, this paper takes a broader stance on this concept. I argue that reactivity is a ubiquitous feature of the psychological subject matter and that this fact is a precondition of experimental research, while also posing potential problems for the experimenter. The latter are connected to the worry about distorted data and experimental artifacts. But what are experimental artifacts and what is the most productive way of dealing with them? In this paper, I approach these questions by exploring the ways in which experimenters in psychology simultaneously exploit and suppress the reactivity of their subject matter in order to produce experimental data that speak to the question or subject matter at hand. Highlighting the artificiality of experimental data, I raise (and answer) the question of what distinguishes a genuine experimental result from an experimental artifact. My analysis construes experimental results as the outcomes of inferences from the data that take material background assumptions as auxiliary premises. Artifacts occur when one or more of these background assumptions are false, such that the data do not reliably serve the purposes they were generated for. I conclude by laying out the ways in which my analysis of data quality is relevant to, and informed by, recent debates about the replicability of experimental results. © 2022, The Author(s).

description: Non-epistemic values play important roles in classificatory practice, such that philosophical accounts of kinds and classification should be able to accommodate them. Available accounts fail to do so, however. Our aim is to fill this lacuna by showing how non-epistemic values feature in scientific classification, and how they can be incorporated into a philosophical theory of classification and kinds. To achieve this, we present a novel account of kinds and classification (the Grounded Functionality Account), discuss examples from biological classification where non-epistemic values play decisive roles, and show how this account accommodates the role of non-epistemic values. © 2022, The Author(s).

description: We present magnetization and Hall effect measurements on the pyrochlore iridate Nd2Ir2O7. Previous muon spin rotation measurements have shown that the system undergoes an unusual transition at T$_M$ = 110 K into a magnetic phase lacking long-range order, followed by a transition at T$_LRO$ = 6 K into a state with long-range magnetic order. We observe a small remnant magnetization when cycling through zero magnetic field at temperatures below T$_M$. Below T$_LRO$, this remnant magnetization increases sharply, and new hysteresis effects appear at a higher field B$_c$ = 2.5 T, while the Hall resistance develops a non-monotonic and hysteretic magnetic field dependence, with a maximum at B$_c$ and signatures of an anomalous Hall effect. The dependence on field sweep direction demonstrates a non-trivial transition into a magnetically ordered state with properties paralleling those of known spin-ice systems and suggests a spin reorientation transition across the metal insulator transition in the A-227 series.

description: This paper investigates the role of land rental markets in livelihood choices using data from 792 farming households in rural Vietnam. First, we cluster households according to livelihood strategies and estimate the determinants of the respective decision. In a second step, we analyze the contribution of rented land in linking smallholders to output markets. Our results suggest that rented land can provide smallholders with an opportunity to increase their agricultural activities and avoid resorting to less remunerative activities such as agricultural wage labor. Moreover, rented crop area increases the probability of market participation as well as the quantity of sales. Our results point to the need for a further liberalization of land rental markets specifically targeted at households that have been excluded from more remunerative livelihood strategies previously. Supporting these households to have access to the assets required to cultivate the additional area is thus recommended. © 2022, The Author(s).

description: In the recent years, mater-wave interferometry has attracted growing attention due to its unique suitability for high-precision measurements and study of fundamental aspects of quantum theory. Diffraction and interference of matter waves can be observed not only at a spatial aperture (such as a screen edge, slit, or grating), but also at a time-domain aperture (such as an absorbing barrier, or "shutter", that is being periodically switched on and off). The wave phenomenon of the latter type is commonly referred to as "diffraction in time". Here, we introduce a versatile, exactly solvable model of diffraction in time. It describes time-evolution of an arbitrary initial quantum state in the presence of a time-dependent absorbing barrier, governed by an arbitrary aperture function. Our results enable a quantitative description of diffraction and interference patterns in a large variety of setups, and may be used to devise new diffraction and interference experiments with atoms and molecules.

description: Single-crystal Czochralski silicon used for photovoltaics is typically supersaturated with interstitial oxygen at temperatures just below the melting point. Oxide precipitates therefore can form during ingot cooling and cell processing, and nucleation sites are typically vacancy-rich regions. Oxygen precipitation gives rise to recombination centres, which can reduce cell efficiencies by as much as 4% (absolute). We have studied the recombination behaviour in p-type and n-type monocrystalline silicon with a range of doping levels intentionally processed to contain oxide precipitates with a range of densities, sizes and morphologies. We analyse injection-dependent minority carrier lifetime measurements to give a full parameterisation of the recombination activity in terms of Shockley-Read-Hall statistics. We intentionally contaminate specimens with iron, and show recombination activity arises from iron segregated to oxide precipitates and surrounding defects. We find that phosphorus diffusion gettering reduces the recombination activity of the precipitates to some extent. We also find that bulk iron is preferentially gettered to the phosphorus diffused layer rather than to oxide precipitates. © 2013 The Authors.

description: The Amaldi 10 Parallel Session C2 on gravitational wave (GW) search results, data analysis and parameter estimation included three lively sessions of lectures by 13 presenters, and 34 posters. The talks and posters covered a huge range of material, including results and analysis techniques for ground-based GW detectors, targeting anticipated signals from different astrophysical sources: compact binary inspiral, merger and ringdown; GW bursts from intermediate mass binary black hole mergers, cosmic string cusps, core-collapse supernovae, and other unmodeled sources; continuous waves from spinning neutron stars; and a stochastic GW background. There was considerable emphasis on Bayesian techniques for estimating the parameters of coalescing compact binary systems from the gravitational waveforms extracted from the data from the advanced detector network. This included methods to distinguish deviations of the signals from what is expected in the context of General Relativity.

description: Urban resilience development at local level requires skills and methodologies that are often not at hand in city administrations. In order to enhance cities’ capacity to resist, absorb and recover from the effects of climate change, the Hprizon2020 project ‘Smart Mature Resilience’ (SMR) is developing standardized approaches and tools to support the development of climate adaptation and resilience strategies. The project has engaged 3 partner cities (Kristiansand, Norway; Glasgow, United Kingdom and Donostia-San Sebastian, Spain) in an iterative, pilot implementation process that presented the tools and trained stakeholders in using them, by discussing how these contribute to the overall resilience building process and how they feed into an integrated management system for resilience planning that can be transferred to the local context of other cities, regions and countries. Developing a co-creation approach has enabled to gather detailed information and understanding on what cities are expecting from this integrated management system for resilience, the so-called European Resilience Management Guideline. All the information gathered has helped cities to highlight existing challenges and associated problems regarding resilience at local level. The following chapter aims initially to present the project and the resilience-building tools it develops and to summarize and comment upon the most important lessons learnt from the pilot implementation process in the three cities.

description: Government debt crisis and recession in Greece cause decline of the welfare state. This has been the result of the attempt of the Greek Government to reduce fiscal and macro-economic vulnerability to debt crisis through dismissals of public employees, cutting wages and pensions, shrinking social welfare public provisions. The state’s adaptation however caused increase of human and social vulnerability and (re)activation of historical and new social risks. On their side, vulnerable people, urban level institutions and social organizations employed novel resilience attitudes to manage the unexpected risks of everyday life and amplified vulnerability, all caused by the crisis. This type resilience at the urban level sometimes is widely beneficial, but other times harmful to the most vulnerable, the environment and the wider public interest, currently or in the future.

Creators: name: Dobricki, Martin

Publisher: name: :unas
Year: 2024

description: Eco-friendly food choice requires that human individuals relate themselves and their natural environment to each other. They may establish this human-environment relation by experiencing their food choices being accompanied by negative or positive changes of the eco-system. Hence, educating human individuals by enabling them to such human-environment experiences may foster their eco- friendly food choice. Yet, this would require inducing climate-related environmental changes on purpose that immediately follow one’s choice of food. We have, therefore, developed a VR consisting in a life-sized virtual environment in which grabbing food is accompanied by climate-related environmental changes or their reversal depending on the food’s carbon footprint. Moreover, we have started to investigate the educational utility of this EcoVR by asking experienced lower secondary school teachers to rate it in controlled experiments. Our findings suggest that the teachers regard EcoVR to be useful for teaching climate-friendly food consumption. Moreover, they regard this educational usefulness of EcoVR to be higher than that of its PC version. Hence, in lower secondary education EcoVR may have the potential to serve pupils for learning climate-friendly food choice. Moreover, it may serve as a digital bridge or «metaverse» between the learning of relevant skills at school and the application of these skills in real life.
Constraints on the Viscosity and Magnetic Field in Hot Accretion Flows around Black Holes

description: The magnitude of the viscosity and magnetic field parameters in hot accretion flows is investigated in low luminosity active galactic nuclei (LLAGNs). Theoretical studies show that a geometrically thin, optically thick disk is truncated at mass accretion rates less than a critical value by mass evaporated vertically from the disk to the corona, with the truncated region replaced by an advection dominated accretion flow (ADAF). The critical accretion rate for such a truncation is a function of the viscosity and magnetic field. Observations of X-ray photon indices and spectral fits of a number of LLAGNs published in the literature provide an estimate of the critical rate of mass accretion and the truncation radius respectively. By comparing the observational results with theoretical predictions, the viscosity and magnetic field parameters in the hot accretion flow region are estimated. Specifically, the mass accretion rates inferred in different sources constrain the viscosity parameter, whereas the truncation radii of the disk, as inferred from spectral fits, further constrain the magnetic field parameter. It is found that the value of the viscosity parameter in the corona/ADAF ranges from 0.17 to 0.5, with values clustered about 0.2-0.3. Magnetic pressure is required by the relatively small truncation radii for some LLAGNs and is found to be as high as its equipartition value with the gas pressure. The inferred values of the viscosity parameter are in agreement with those obtained from the observations of non-stationary accretion in stellar mass black hole X-ray transients. This consistency provides support for the paradigm that a geometrically thin disk is truncated by means of a mass evaporation process from the disk to the corona at low mass accretion rates.

description: We present the COLIBRI code for computing the evolution of stars along the TP-AGB phase. Compared to purely synthetic TP-AGB codes, COLIBRI relaxes a significant part of their analytic formalism in favour of a detailed physics applied to a complete envelope model, in which the stellar structure equations are integrated from the atmosphere down to the bottom of the hydrogen-burning shell. This allows to predict self-consistently: (i) the effective temperature, and more generally the convective envelope and atmosphere structures, correctly coupled to the changes in the surface chemical abundances and gas opacities; (ii) sphericity effects in the atmospheres; (iii) the core mass-luminosity relation and its break-down due to hot bottom burning (HBB) in the most massive AGB stars, (iv) the HBB nucleosynthesis via the solution of a complete nuclear network (pp chains, and the CNO, NeNa, MgAl cycles), including also the production of 7Li via the Cameron-Fowler beryllium transport mechanism; (v) the chemical composition of the pulse-driven convective zone; (vi) the onset and quenching of the third dredge-up, with a suitable temperature criterion. At the same time COLIBRI pioneers new techniques in the treatment of the physics of stellar interiors. It is the first evolutionary code ever to use accurate on-the-fly computation of the equation of state for roughly 800 atoms, ions, molecules, and of the Rosseland mean opacities throughout the deep envelope. Another distinguishing aspect of COLIBRI is its high computational speed. This feature is necessary for calibrating the uncertain parameters and processes that characterize the TP-AGB phase, a step of paramount importance for producing reliable stellar population synthesis models of galaxies up to high redshift.

description: The phenomenon of urban heat islands (UHI) in Athens is well documented (LIVADA, S ANTAMOURIS and ASSIMAKOPOULOS 2007; MIHALAKAKOU , S ANTAMOURIS , P APANIKOLAOU , CARTALIS and T SANGRASSOULIS 2004). Studies range from descriptive research on the phenomenon and its development for the last decades to impact studies and adaption measures (S ANTAMOURIS et al. 2015). However, the relevance of this topic is shown by this year’s temperatures of over 40°C in the inner city and its densely populated districts accompanied by increased ozone levels (E UROMETEO 2017, www). Impacts are of environmental, economic and social nature (ibid.). The “Green Networks Exarchia” is a plan on how to tackle the problems of urban heat island in the city district of Exarchia in Athens. The “Green Networks Exarchia” describes the idea of connecting parks and micro-parks by transforming the streets into green corridors. The overall goal is to reduce the problems heat islands to determine the problem in general, to identify the problem in the district of Exarchia, to assess the goals and to elaborate ways to improve the situation. To conduct these tasks, a variety of knowledge and different points of view were necessary. This included, on the one hand, the views from different academic fields such as architecture, environmental planning and urban planning and on the other hand considers the different scales of the problem. Each field player an important role to achieve the results. Environmental planning, for instance, played a huge role in identifying the problem and designing the ways of how to green the spaces. The field of architecture contributed a lot in terms of concrete measures and how to implement them in the city district. The field of urban planning was important to coordinate the project and to plan the network itself. Although the project focused on the district level, all scales were important to observe. While the likelihood of heat waves react to the increase of heat days and UHI must be implemented on the local level.

description: In this work we analyze a non--interacting one dimensional polymer Bose--Einstein condensate in an harmonic trap within the semiclassical approximation. We use an effective Hamiltonian coming from the polymer quantization that arises in loop quantum gravity. We calculate the number of particles in order to obtain the critical temperature. The Bose--Einstein functions are replaced by series, whose high order terms are related to powers of the polymer length. It is shown that the condensation temperature presents a shift respect to the standard case, for small values of the polymer scale. In typical experimental conditions, it is possible to establish a bound for $λ^{2}$ up to $ \lesssim 10 ^{-16}$m$^2$. To improve this bound we should decrease the frequency of the trap and also decrease the number of particles.

description: We study effects of the spontaneous symmetry-breaking (SSB) in solitons built of the dipolar Bose-Einstein condensate (BEC), trapped in a dual-core system with the dipole-dipole interactions (DDIs) and hopping between the cores. Two realizations of such a matter-wave coupler are introduced, weakly- and strongly-coupled. The former one in based on two parallel pipe-shaped traps, while the latter one is represented by a single pipe sliced by an external field into parallel layers. The dipoles are oriented along axes of the pipes. In these systems, the dual-core solitons feature the SSB of the supercritical type and subcritical types, respectively. Stability regions are identified for symmetric and asymmetric solitons, and, in addition, for non-bifurcating antisymmetric ones, as well as for symmetric flat states, which may also be stable in the strongly-coupled system, due to competition between the attractive and repulsive intra- and inter-core DDIs. Effects of the contact interactions are considered too. Collisions between moving asymmetric solitons in the weakly-symmetric system feature elastic rebound, merger into a single breather, and passage accompanied by excitation of intrinsic vibrations of the solitons, for small, intermediate, and large collision velocities, respectively. A PT-symmetric version of the weakly-coupled system is briefly considered too, which may be relevant for matter-wave lasers. Stability boundaries for PT-symmetric and antisymmetric solitons are identified.

description: Athens is exposed to high heat stress that has negative effects on its residents. This paper presents an approach to tackle the problem by empowering the community and strengthening local solidarity. The area examined in this paper has a particular attribute: the park “Pedion Areos”. It presents a large potential for residents to escape heat stress. Unlike most areas within an urban structure, the park is mainly unsealed, leaving the surface permeable to water which lowers the urban heat island effect. The park’s vegetation cools the area by evaporation and providing shade (KLEEREKOPER et al 2012). Due to the limited monetary possibilities regarding the change of grey urban infrastructure, the concept which is presented in this paper focuses on strengthening the opportunities provided by the park and other potential green areas as well as empowering the people to responsibly participate in the district’s development in order to create a healthy living environment for its residents. During the Summer School, on-site inspections of the designated study area were made. By doing that, the area was examined for the subjective feeling of heat, safety and social meetingpoints. Moreover, informal expert knowledge of the area was provided by Greek Architecture students. Detailed analyses of the constructed and social structure were made possible by Greek Census Data and the Athens Office of Resilience and Sustainability. In order to scientifically justify the aspired strategy, further literature research was done. A big part of this research served the purpose of answering one important key question: What constitutes resilience of a society or neighbourhood? Linked to the crucial role green infrastructure in cities plays in answering this question, the various benefits of urban green were identified. In addition to that, the role of urban planners in the process of making a community more resilient against external threats such as heat islands was debated. Eventually, the key findings presented in this paper were brought together in the depiction of an ideal participatory planning process. The implementation of the presented concept has the potential to improve the current vulnerability of the neighbourhood around the “Pedion Areos” to heat stress and to furthermore generate a greater sense of community and belonging.

description: Visual language and culture are co-constitutive and constantly evolving. This transformation is more pronounced in the contemporary visual literacy landscape especially with widely used social media and more democratic technologies, such as smartphone cameras, which are used for myriad purposes and in diverse ways. These uses and purposes vary by culture and demographics but little is understood about how smartphone cameras shape contemporary Western ways of seeing: visual culture and literacy. Specifically, this study seeks to explore and identify how people living in Australia use their smartphone cameras to document their everyday lives. It also explores how these devices influence the participants’ visual languages and literacies. To analyse these changes, this study adopts a two-method approach. First, 30 participants were recruited from three different age groups. These participants donated a consistent two weeks of the images on their camera rolls for analysis. These images were then subjected to an 11-variable analysis. Second, 23 participants followed through with an interview to contextualise their photographic behaviour and identify the aspects they perceive shape their ways of seeing. These two methods allow an understanding of who or what is photographed as well as how and why these participants made images in certain ways.
