description: Към род Abies принадлежат около 50 вида призхождащи предимно от умерените региони на северното полукълбо (http://www.discoverlife.org). Те играят съществена екологична роля за околната среда в регионите на своя произход. Няколко вида имат важно икономическо значение като източник за производство на дървесина и извън тези региони. Други видове са високо ценени като декоративни растения. Поради естествената им конична форма, цвят и силни прирасти, същинските ели, особено видове със продължително задържане на иглите, са много подходящи за използване като коледни елхи и клонки. В Европа най-често срещаният вид, отглеждан като коледна елха е Нордмандска ела, докато в САЩ преобладават Фрейзър (Abies fraseri) и Благородна ела (Abies procera). Други видове ели които се предлагат на пазара като коледни елхи са Балсамовата ела (A. balsamea), Грандовата ела (A. grandis), Корейската ела (Abies koreana), Сибирската ела (A. sibirica), Субалпийската ела (A. lasiocarpa), Турската мура (А. bornmuelleriana) и Бялата мура (A. concolor). Благородната ела е основен вид за производство на клонки, както в Европа така и в САЩ.

description: We extend the knowledge on dispositions toward ridicule and being laughed at (gelotophobia, gelotophilia, and katagelasticism) by testing their localization in a system of maladaptive personality traits. Across two studies, we used self-ratings (Ntotal = 1,438) and informant reports (Ntotal = 378 dyads). The differential associations for the dispositions fit well with expectations: Negative Affectivity, Detachment and Psychoticism characterize gelotophobia; gelotophilia relates to Disinhibition and low Detachment; and predominantly Antagonism characterizes katagelasticism. Facet-wise analyses (Study 2) allowed more fine-grained descriptions. Condition-based regression analyses showed that the laughter-related dispositions did not relate to discrepancies of self-informant views on maladaptive personality traits. Our findings contribute to understand the maladaptive personality traits of gelotophobes, gelotophiles, and katagelasticists.

description: Multi-planet systems orbiting M dwarfs provide valuable tests of theories of small planet formation and evolution. K2-3 is an early M dwarf hosting three small exoplanets (1.5-2.0 Earth radii) at distances of 0.07-0.20 AU. We measure the high-energy spectrum of K2-3 with HST/COS and XMM-Newton, and use empirically-driven estimates of Ly-alpha and extreme ultraviolet flux. We use EXOFASTv2 to jointly fit radial velocity, transit, and SED data. This constrains the K2-3 planet radii to 4% uncertainty and the masses of K2-3b and c to 13% and 30%, respectively; K2-3d is not detected in RV measurements. K2-3b and c are consistent with rocky cores surrounded by solar composition envelopes (mass fractions of 0.36% and 0.07%), H2O envelopes (55% and 16%), or a mixture of both. However, based on the high-energy output and estimated age of K2-3, it is unlikely that K2-3b and c retain solar composition atmospheres. We pass the planet parameters and high-energy stellar spectrum to atmospheric models. Dialing the high-energy spectrum up and down by a factor of 10 produces significant changes in trace molecule abundances, but not at a level detectable with transmission spectroscopy. Though the K2-3 planets span the small planet radius valley, the observed system architecture cannot be readily explained by photoevaporation or core-powered mass loss. We instead propose 1) the K2-3 planets are all volatile-rich, with K2-3d having a lower density than typical of super-Earths, and/or 2) the K2-3 planet architecture results from more stochastic processes such as planet formation, planet migration, and impact erosion.

description: From the past decade outlier detection has been in use. Detection of outliers is an emerging topic and is having robust applications in medical sciences and pharmaceutical sciences. Outlier detection is used to detect anomalous behaviour of data. Typical problems in Bioinformatics can be addressed by outlier detection. A computationally fast method for detecting outliers is shown, that is particularly effective in high dimensions. PrCmpOut algorithm make use of simple properties of principal components to detect outliers in the transformed space, leading to significant computational advantages for high dimensional data. This procedure requires considerably less computational time than existing methods for outlier detection. The properties of this estimator (Outlier error rate (FN), Non-Outlier error rate(FP) and computational costs) are analyzed and compared with those of other robust estimators described in the literature through simulation studies. Numerical evidence based Oxazolines and Oxazoles molecular descriptor dataset shows that the proposed method performs well in a variety of situations of practical interest. It is thus a valuable companion to the existing outlier detection methods.

description: Graphene nanoribbons provide an ideal platform for electronic interferometry in the Integer Quantum Hall regime. Here, we solve the time-dependent four-component Schroedinger equation for single carriers in graphene and expose several dynamical effects of the carrier localization on their transport characteristics in pn junctions. We simulate two kinds of Mach-Zender Interferometers (MZI). The first is based on Quantum Point Contacts and is similar to traditional GaAs/AlGaAs interferometers. As expected, we observe Aharonov-Bohm oscillations and phase averaging. The second is based on Valley Beam Splitters, where we observe unexpected phenomena due to the intersection of the Edge Channels that constitute the MZI. Our results provide further insights into the behavior of graphene interferometers. Additionally, they highlight the operative regime of such nanodevices for feasible single-particle implementations.

The detector recorded individual synchrotron radiation pulses with an x-ray photon energy of 14.4 keV and repetition rate of about 5 MHz. The second-order intensity correlation function was measured simultaneously at different spatial separations that allowed to determine the transverse coherence length at these x-ray energies. The measured values are in a good agreement with theoretical simulations based on the Gaussian Schell-model.

description: Resonant cooling of different nuclear isotopes manifested in optically-induced nuclear magnetic resonances (NMR) is observed in n-doped CdTe/(Cd,Mg)Te and ZnSe/(Zn,Mg)Se quantum wells and for donor-bound electrons in ZnSe:F and GaAs epilayers. By time-resolved Kerr rotation used in the regime of resonant spin amplification we can expand the range of magnetic fields where the effect can be observed up to nuclear Larmor frequencies of 170 kHz. The mechanism of the resonant cooling of the nuclear spin system is analyzed theoretically. The developed approach allows us to model the resonant spin amplification signals with NMR resonances.

title: Religion, politics and conflict resolution in the Democratic Republic of Congo: An ethnographic study of the role of Christian clergy in the ethnic identity conflicts in Eastern Congo 1990 - 2023
Creators: name: Ntung, Alex
Publisher: name: University of Kent
Year: 2024

description: This study explores the role of local Christian clergy in resolving or exacerbating violence related to indigeneity and ethnic identity in the Democratic Republic of Congo (DRC). It focuses on understanding the interactions of religious elites with politics, power and ethnicity and analyses their actions, personal rationales, practices, behaviours, and responses. The thesis draws on over six months of ethnographic fieldwork conducted between October 2020 and February 2022, mainly in the DRC, Belgium and Rwanda. It adopts a qualitative and interpretive methodology involving fieldwork, semi structured interviews, focus groups, observations, and archival research. The study draws from a five-dimensional model of religion in peace and conflict by Fraser and Owen. It also makes use of original metaphors based on Congolese house and village plans, to elucidate the hidden meanings and multifaceted modes of Congolese thought. The insider position of the researcher is used to explain the relevance of the religious in peacebuilding within an existing secular approach. The use of specifically Congolese metaphors also contributes to an understanding of the DRC society, the mindsets of peacemakers and their interactions with an environment of ethnic conflict. The research findings demonstrate, firstly, that the symbiotic relationship between politics and religion presents a fundamental obstacle to peacebuilding. The thesis also demonstrates that ethnicity and tribal loyalties frequently take precedence over fundamental religious tenets and the claimed religious values of peace. It observes that
Finally, the thesis strongly suggest that Christian clergy have been ambiguous, silent, complicit, or complacent concerning violence against Tutsi communities, particularly throughout the ethnic identity crises of the 1990s and in more recent violence in North and South Kivu. The findings contribute to existing literature by arguing that the role of religious leaders in peace and conflict is essential but also multifaceted and contradictory. This finding suggests clergy's pluralistic positions in conflict, which extend from existing scholarship that highlights the ambivalent roles of religious leaders in peace making. The thesis claims that clergy could play a pivotal, constructive role in creating an environment that enables peaceful coexistence if they were able to act independently of allegiance to ethnicity, politics, and power.
Relativistic Spectroscopy of Plasma Embedded Li-like Systems with the Screening Effects in the Two-body Debye Potentials

description: The spectroscopic properties of Li atom and Li-like Ca and Ti ions in the plasma environment are investigated using a relativistic coupled-cluster (RCC) method. Assuming the plasma is of low density and very hot, we consider the Debye model with two approximations by accounting the screening effects: (i) in the nuclear potential alone and (ii) in both the nuclear and the electron-electron interaction potentials. First, the calculations for the energies and the lifetimes of the atomic states are carried out for the plasma free systems in order to check their accuracies following which they are investigated in the plasma environment. It is observed that screenings in the electron-electron interaction potentials stabilize the systems more than the case when the screenings present only in the nuclear potential. Similarly, the earlier predicted blue and red shifts in the $Δn=0$ and $Δn \ne 0$ transition lines (with the principal quantum number $n$) of the Li-like ions change significantly in the case (ii) approximation. The level-crossings among the energy levels are observed for the large screening effects which seem to be prominent in the states of higher orbital angular momentum. The lifetimes of many low-lying states and the relative line-intensities of the allowed transitions are estimated considering different plasma screening strengths.

description: The Weak Turbulence Theory has been applied to waves in thin elastic plates obeying the Föppl-Von Kármán dynamical equations. Subsequent experiments have shown a strong discrepancy between the theoretical predictions and the measurements. Both the dynamical equations and the Weak Turbulence Theory treatment require some restrictive hypotheses. Here a direct numerical simulation of the Föppl-Von Kármán equations is performed and reproduces qualitatively and quantitatively the experimental results when the experimentally measured damping rate of waves $γ_\mathbf{k}= a + bk^2$ is used. This confirms that the Föppl-Von Kármán equations are a valid theoretical framework to describe our experiments. When we progressively tune the dissipation so that to localize it at the smallest scales, we observe a gradual transition between the experimental spectrum and the Kolmogorov-Zakharov prediction. Thus it is shown dissipation has a major influence on the scaling properties stationary solutions of weakly non linear wave turbulence.

description: This paper introduces Sketched Reality, an approach that combines AR sketching and actuated tangible user interfaces (TUI) for bidirectional sketching interaction. Bi-directional sketching enables virtual sketches and physical objects to "affect" each other through physical actuation and digital computation. In the existing AR sketching, the relationship between virtual and physical worlds is only one-directional -- while physical interaction can affect virtual sketches, virtual sketches have no return effect on the physical objects or environment. In contrast, bi-directional sketching interaction allows the seamless coupling between sketches and actuated TUIs. In this paper, we employ tabletop-size small robots (Sony Toio) and an iPad-based AR sketching tool to demonstrate the concept. In our system, virtual sketches drawn and simulated on an iPad (e.g., lines, walls, pendulums, and springs) can move, actuate, collide, and constrain physical Toio robots, as if virtual sketches and the physical objects exist in the same space through seamless coupling between AR and robot motion. This paper contributes a set of novel interactions and a design space of bi-directional AR sketching. We demonstrate a series of potential applications, such as tangible physics education, explorable mechanism, tangible gaming for children, and in-situ robot programming via sketching.

description: Examination of the temporal variability properties of several strong optical recombination lines in a large sample of Galactic Wolf-Rayet (WR) stars reveals possible trends, especially in the more homogeneous WC than the diverse WN subtypes, of increasing wind variability with cooler subtypes. This could imply that a serious contender for the driver of the variations is stochastic, magnetic subsurface convection associated with the 170 kK partial-ionization zone of iron, which should occupy a deeper and larger zone of greater mass in cooler WR subtypes. This empirical evidence suggests that the heretofore proposed ubiquitous driver of wind variability, radiative instabilities, may not be the only mechanism playing a role in the stochastic multiple small-scaled structures seen in the winds of hot luminous stars. In addition to small-scale stochastic behaviour, subsurface convection guided by a global magnetic field with localized emerging loops may also be at the origin of the large-scale corotating interaction regions as seen frequently in O stars and occasionally in the winds of their descendant WR stars.

description: We report the study of metal-STO-metal memristors where the doping concentration in STO can be fine-tuned through electric field migration of oxygen vacancies. In this tunnel junction device, the evolution of the Density Of States (DoS) can be followed continuously across the Metal-Insulator Transition (MIT). At very low dopant concentration, the junction displays characteristic signatures of discrete dopants levels. As the dopant concentration increases, the semiconductor band gap fills in but a soft Coulomb gap remains. At even higher doping, a transition to a metallic state occurs where the DoS at the Fermi level becomes finite and Altshuler-Aronov corrections to the DoS are observed. At the critical point of the MIT, the DoS scales linearly with energy $N(\varepsilon) \sim \varepsilon$, the possible signature of multifractality.

description: The Shockley-Queisser (S-Q) theory defines the thermodynamic upper limits for Jsc, Voc, FF, and efficiency of a solar cell. The classical calculation assumes an abrupt onset of absorption at the band-edge, perfect absorption for all energies above the bandgap, and absence of non-radiative recombination. These assumptions are never satisfied for any practical solar cell. In this paper, we explain how the S-Q limits are redefined in the presence of the non-ideal optical effects, and we provide closed-form analytical expressions for the new limits for Jsc, Voc, and FF. Remarkably, these new limits can be achieved to a very high degree, even with significantly imperfect materials.

description: The connection between unconventional superconductivity and charge density waves (CDW) has intrigued the condensed matter community and found much interest in the recently discovered superconducting Kagome family of AV$_3$Sb$_5$ (A = K, Cs, Rb). Xray diffraction and Raman spectroscopy measurements established that the CDW order in CsV$_3$Sb$_5$ comprises of a 2x2x4 structure with stacking of layers of star-of-David (SD) and inverse-star-of-David (ISD) pattern along the $c$-axis direction. Such interlayer ordering will induce a vast normalization of the electronic ground state; however, it has not been observed in Fermi surface measurements. Here we report quantum oscillations of CsV$_3$Sb$_5$ using tunnel diode oscillator frequency measurements. We observed a large number of frequencies, many of which were not reported. The number of frequencies can not be explained by DFT calculations when only SD or ISD distortion is considered. Instead, our results are consistent with calculations when interlayer ordering is taken into account, providing strong evidence that CDW phase of CsV$_3$Sb$_5$ has complicated structure distortion which in turn has dramatic effects on the Fermi surface properties.

ECLOUD12 discussed new EC observations at existing machines including LHC, CesrTA, PETRA-3, J-PARC, and FNAL MI; latest experimental efforts to characterize the EC - including EC diagnostics, experimental techniques, mitigation techniques such as coating and conditioning, advanced chemical and physical analyses of various vacuum-chamber surfaces, beam instabilities and emittance growth -; the status of EC physics models and (new, more versatile and additional) simulation codes and their comparison with recently acquired experimental data; and the mitigation requirements and potential performance limitations imposed by the EC on upgraded and future machines, including HL-LHC, FAIR, ILC, Project-X, SuperB and SuperKEKB. A dedicated session addressed problems related to RF breakdown and multipacting for space applications. A number of open questions and future R&D needs were identified.

Resilience in Indigenous Australian families : how individual, family, and community‚ÄövÑv´level protective factors contribute to wellbeing
Creators: name: Pisanu, N
Publisher: name: University of Tasmania
Year: 2023

description: In sociological research, increasing attention has been afforded to the examination of protective factors that contribute to resilience, particularly of those experiencing disadvantage. Resilience is the process of maintaining positive functioning during times of adversity, through protective resources that buffer against the negative effects of stress (Masten, 2018). While individual capacity to access protective factors is important, the ability of surrounding social environments to provide and give meaning to these resources is also crucial (Ungar, 2012b). Many Aboriginal and Torres Strait Islander people are inequitably exposed to an atypical level of stress throughout their lives, stemming from the devastating consequences of colonisation and continued marginalisation in Australia (Walter, Dodson, & Barnes, 2017a). Despite this disproportionate vulnerability to risk and adversity, resilience research in an Indigenous Australian context is limited. For Australian Indigenous people, unique aspects such as engagement with culture, support from extended family and kinship networks, and community connectedness contribute to their ability to overcome adversity (Dobia et al., 2014; McLennan, 2015). While qualitative findings support this (McLennan, 2015), limited quantitative evidence has been found. Further, no known prior research has examined resilience in both parents and children using a national sample of Indigenous Australians. This thesis explores the role of individual-, family-, and community-level protective factors and their contribution to resilience for Australian Indigenous families, and demonstrates how the findings have implications for social and health policy. It uses quantitative methods, drawing national data from Wave 10 of the Longitudinal Study of Indigenous Children (LSIC) to explore the protective factors that contribute to resilience in Indigenous Australian children aged between 9 and 14 years (n=1,270) and their caregivers (n=1,218). Multiple logistic regression is used to model the protective factors that contribute to positive outcomes, compared to negative outcomes, in high-stress contexts. Findings reveal evidence of individual- (e.g., social skills) and community-level (e.g., engagement with school) resources having protective effects for Indigenous children, with family-level (e.g., extended family support) factors being the strongest predictors of resilient functioning in caregivers. Findings are used to make policy recommendations based on decolonising principles, responding to contemporary demands for evidence-based policy. Decolonising approaches to research and policy include: (i) self-determination; (ii) investment in community-controlled services and place-based strategies; (iii) the sharing of power; and (iv) prioritising data sovereignty.

description: The Galileo Project is the first systematic scientific research program in search for potential astro8 archaeological artifacts or remnants of extraterrestrial technological civilizations (ETCs) or potentially active equipment near Earth. Taking a path not taken, it conceivably may pick some low-hanging fruit, and without asserting probabilities -- make discoveries of ETC-related objects, which would have far-reaching implications for science and our worldview.

description: In this work, we first define relations on the fuzzy parametrized soft sets and study their properties. We also give a decision making method based on these relations. In approximate reasoning, relations on the fuzzy parametrized soft sets have shown to be of a primordial importance. Finally, the method is successfully applied to a problems that contain uncertainties.

Coronation of Charles III from the Perspective of Liturgical Studies
Creators: name: Lloyd, Daniel
Publisher: name: Ex Fonte - Journal of Ecumenical Studies in Liturgy
Year: 2023

description: The coronation of Charles III at Westminster Abbey on 6 May 2023 was the first such occasion for seventy years, and one which took place in a very different national, political, and indeed liturgical context from that which attended his mother Elizabeth II’s coronation in 1953. This article explores the continuities and changes in the texts, rites, and gestures of this unique liturgy (whilst also acknowledging that it sits in a tradition of liturgical articles being published around the time of coronations). The article argues that issues like change and continuity, and the anticipation and management of perceptions, have always been engaged with and instrumentalized by those responsible for compiling and working out the coronation liturgy in England: in 2023 that group included, as on previous occasions, the Royal Household, the Archbishop of Canterbury, and the broadcast media. The coronation liturgy is one in which adaptation to the perceived needs of the moment has always played an important role, and this article demonstrates how, in 2023, this is particularly evident in the text of the liturgical rite as well as in its performance.

Raman Scattered Ne VII$λ$973 at 4881 Å in the Symbiotic Star V1016 Cygni

description: We present the high resolution spectra of the symbiotic star V1016 Cygni obtained with the Bohyunsan Optical Echelle Spectrograph in 2003 and 2005, from which we find a broad emission feature at 4881 Å. We propose that this broad feature is formed from Raman scattering of Ne VII$\lambda973$ by atomic hydrogen. Thus far, the detection of Raman scattered lines by atomic hydrogen is limited to O VI$λλ$1032, 1038 and He II$λλ$940, 972 and 1025. With the adoption of the center wavelength 973.302 Å of Ne VII$λ$973 and consideration of the air refractive index of $n_{air}=1.000279348$, the atomic line center of the Raman scattered Ne VII feature is determined to be 4880.53 Å. The total cross section at the line center of Ne VII$\lambda973$ is computed to be $2.62\times 10^{-22}{\rm\ cm^2}$ with the branching ratio of 0.17. We perform Monte Carlo simulations to fit the Raman scattered Ne VII$\lambda973$. Assuming that the Ne VII and He II emission regions share the same kinematics with respect to the neutral scattering region, we find that the Raman scattered He II$λ$972 at 4850 Å and Ne VII$λ$973 at 4881 Å are excellently fitted. We also propose that the He II and Ne VII emission regions were stationary with respect to the H I region in 2003 but that they were receding from it with a velocity $\sim 20{\rm\ km\ s^{-1}}$ in 2005.

description: We present deep HI observations of three compact high-velocity clouds (CHVCs). The main goal is to study their diffuse warm gas and compact cold cores. We use both low- and high-resolution data obtained with the 100 m Effelsberg telescope and the Westerbork Synthesis Radio Telescope (WSRT). The combination is essential in order to study the morphological properties of the clouds since the single-dish telescope lacks a sufficient angular resolution while the interferometer misses a large portion of the diffuse gas. Here single-dish and interferometer data are combined in the image domain with a new combination pipeline. The combination makes it possible to examine interactions between the clouds and their surrounding environment in great detail. The apparent difference between single-dish and radio interferometer total flux densities shows that the CHVCs contain a considerable amount of diffuse gas with low brightness temperatures. A Gaussian decomposition indicates that the clouds consist predominantly of warm gas.

description: Umfangreiche Forschungsarbeiten aus Kulturwissenschaft, Ethnologie und Archäologie sowie weiteren sozialwissenschaftlichen Disziplinen liegen zum Themenfeld „Materielle Kultur“ vor. Die Forschung zur materiellen Kultur thematisiert die Bedeutsamkeit materieller Objekte für die herstellenden und nutzenden Menschen sowie damit verbundene Wahrnehmungs- und Umgangsweisen. Diese Arbeiten sind didaktisch für den unterrichtlichen Umgang mit Objekten von Bedeutung, weil sie bestehende Traditionen aus dem Realien- und Anschauungsunterricht und später im Umgang mit den heimatkundlichen Sammlungen hinterfragen. Ausgehend von Konzepten zur Erforschung materieller Kultur können zudem Ansätze für objektbezogene Interaktionen in Sachlernprozessen von Vor- und Grundschulkindern weiterentwickelt werden.

description: This whitepaper describes part of our vision we call Sensemaking Architecture. A vision that is based on our understanding as experienced enterprise architects about sensing and perception, managing complexity, applying ethical thinking. In this paper we add to this vision a way to translate the purpose of an organisation to a way of working for enterprise architects that honours the challenges of a complex and changing environment. Inspired by psychology, industrial design, sociology, and systems theory, we introduce a model with three levels.
 On the first level we are making sense. What purpose does this organisation have, and what sub-systems are there? We give some perspectives to help find these subsystems. On the second level, for each sub-system we change situationally. What purpose does this sub-system have, and what changes are needed? We present a way of identifying the situation and give a pattern to help govern and guide changes. This comprises a situational architecture approach based on combining architectural method fragments. On the third level we change via a structured way of working, using best-practices, specialised working-regimes and standard methods, suited to the circumstances of the change.
Relational causality and classical probability: Grounding quantum phenomenology in a superclassical theory

description: By introducing the concepts of "superclassicality" and "relational causality", it is shown here that the velocity field emerging from an n-slit system can be calculated as an average classical velocity field with suitable weightings per channel. No deviation from classical probability theory is necessary in order to arrive at the resulting probability distributions. In addition, we can directly show that when translating the thus obtained expression for said velocity field into a more familiar quantum language, one immediately derives the basic postulate of the de Broglie-Bohm theory, i.e. the guidance equation, and, as a corollary, the exact expression for the quantum mechanical probability density current. Some other direct consequences of this result will be discussed, such as an explanation of Born's rule and Sorkin's first and higher order sum rules, respectively.

description: Wie leben Kinder (in der Großstadt)? Wie erschließen sich Kinder den sie umgebenden Raum und wie nutzen sie diesen? Diesen Fragen ist Martha Muchow schon in den 1920er und frü-hen 1930er Jahren gemeinsam mit Studierenden der 1919 neu gegründeten Universität Hamburg im Arbeiterstadtteil Hamburg Barmbek nachgegangen. Im Rahmen von Praktika ließ sie Studierende zum Lebensraum des Großstadtkindes Beobachtungen durchführen, um mit ihnen am erhobenen Material darüber zu reflektieren, wie Kinder in ihrer Eigenart und Differenz zu Erwachsenen ihre großstädtische Umwelt wahrnehmen (vgl. Muchow & Muchow 2012 [1935], S. 79). Im Folgenden wird zunächst die theoretische Rahmung erläutert. In knappen Worten wird darauf eingegangen, was für eine für ihre Zeit neuartige Sicht Martha Muchow auf Kinder wirft und wie sich Kindheit in den letzten Jahren verändert hat. Im Anschluss daran erfolgt die empirische Studie, die exemplarisch am Beispiel des Volksparks Wuhlheide danach fragt, wie sich Kinder im Vergleich zu Erwachsenen heute einen Park aneignen. Hierfür wird – ganz im Sinne Martha Muchows – zunächst die Wuhlheide als Ort beschrieben, statistisch erfasst, an welchen konkreten Orten Kinder sich aufhalten, daraufhin in einer längeren dichten Be-schreibung Einblicke in die Raumaneignung von Kindern (Jugendlichen und Erwachsenen) im Park gegeben und anschließend analysiert, wie Kinder in ihrer Eigenart und Differenz zu Erwachsenen ihre großstädtische Umwelt beleben.

description: A skyrmion is a topological texture in the continuum field theory. Recent experimental observation of skyrmions in chiral magnet evokes a flourish of its extensive study. Skyrmion is expected to be a key component of the next generation spintronics device called skyrmionics. On the other hand, there is a well established memory device encoded by a sequence of domain walls. A skyrmion carries a topological number, whereas a domain wall does not. Nevertheless, we show a conversion is possible between a skyrmion and a domain-wall pair by connecting wide and narrow nanowires, enabling the information transmission between skyrmion device and domain-wall device. Our results will be the basis of a hybrid device made of skyrmions and domain walls, where the encoded information in domain walls is converted into skyrmions, and then read out by converting the skyrmions back to domain walls after a functional control of the skyrmions.
