description: We investigate the synchronization phenomenon between two Spin-transfer Torque Nano-Oscillators (STNOs) of different frequencies in two pillar systems under vortex configuration detunings or driving frequencies. The oscillators' mutual synchronization occurs through magnetic dipolar interaction. Our micromagnetic simulations show that an amplitude fluctuation referred to as $Γ_p$ has a significant impact on determining the synchronization frequency. The evolution of frequency and amplitude fluctuation rate in two different oscillator sizes versus external perpendicular field are compared and discussed. Our results reveal that the oscillator with lower $Γ_p$, referred to as the "Leader" oscillator, leads the synchronization process. As such, the "follower" oscillator adjusts its frequency as to that of the "Leader", thus achieving synchronization. We believe that taking $Γ_p$ into consideration can help in controlling synchronization frequencies in future building blocks of any network multi-array spintronics' devices.

description: The sustainability of infrastructure projects is becoming increasingly important issue in engineering practice. This means that in the future the construction materials will be selected on the basis of the contribution they can make to reach sustainability requirements. Geopolymers are materials based on by-products from industries. By using geopolymer concrete technology it is possible to reduce our waste and to produce concrete in the environmental-friendly way. An 80% or greater reduction of greenhouse gases compared with Ordinary Portland Cement (OPC) can be achieved through geopolymer technology. However, there are limited practical applications and experience. For a broad and large scale industrial application of geopolymer concrete, challenges still exist in the technological and engineering aspects. The main goal of GeoCon Bridge project was to develop a geopolymer concrete mixture and to upscale it to structural application. The outputs of projects provide input for development of recommendations for structural design of geopolymer based reinforced concrete elements. Through a combination of laboratory experiments on material and structural elements, structural design and finite element simulations, and based on previous experience with OPC concrete, knowledge generated in this project provides an important step towards a “cement free” construction. The project was performed jointly by three team members: Microlab and Group of Concrete Structures from Technical University of Delft and Technical University of Eindhoven.

description: We propose a hybrid magnonic-oscillator system based on the combination of a spin transfer auto-oscillator and a magnonic waveguide to open new perspectives for spin-wave based circuits. The system is composed of a spin transfer oscillator based on a vortex state which is dipolarly coupled to a nanoscale spin-wave waveguide with longitudinal magnetization. In its auto-oscillating regime, the oscillator emits coherent spin waves with tunable and controllable frequencies, directions and amplitudes into the waveguide. We demonstrate the principle of this method using micromagnetic simulations and show that reconfiguration of the system is possible by changing the chirality and polarity of the magnetic vortex. Spin waves are emitted into the waveguide with high non-reciprocity and the preferred direction depends on the core polarity of the vortex. In contrast, different vortex chiralities lead to different amplitudes of the emitted waves. Our findings open up a novel way to design an agile spintronic device for the coherent and tunable generation of propagating spin waves.

description: It is well known that Majorana neutrinos have a pure axial neutral current interaction while Dirac neutrinos have the standard vector-axial interaction. In spite of this crucial difference, usually Dirac neutrino processes differ from Majorana processes by a term proportional to the neutrino mass, resulting in almost unmeasurable observations of this difference. In the present work we show that once the neutrino polarization evolution is considered, there are clear differences between Dirac and Majorana scattering on electrons. The change of polarization can be achieved in astrophysical environments with strong magnetic fields. Furthermore, we show that in the case of unpolarized neutrino scattering onto polarized electrons, this difference can be relevant even for large values of the neutrino energy.

description: The main objective of the study is to determine the probability distributions of the geomagnetic Dst index as a function of the coronal mass ejection (CME) and solar flare parameters for the purpose of establishing a probabilistic forecast tool for the geomagnetic storm intensity. Several CME and flare parameters as well as the effect of successive-CME occurrence in changing the probability for a certain range of Dst index values, were examined. The results confirm some of already known relationships between remotely-observed properties of solar eruptive events and geomagnetic storms, namely the importance of initial CME speed, apparent width, source position, and the associated solar flare class. In this paper we quantify these relationships in a form to be used for space weather forecasting in future. The results of the statistical study are employed to construct an empirical statistical model for predicting the probability of the geomagnetic storm intensity based on remote solar observations of CMEs and flares.
Garden Thinking in Cities of Tomorrow

description: Since the middle of the 19th century, when the term ‘landscape architecture’ began to replace the hitherto common term ‘garden art’, the garden as a work of art and gardening, understood as a predominantly decorative activity, stood in the critical discussion about the future of the metropolises. It was not only architects and urban planners who repeatedly questioned the value of ornamental gardens in the city. Against the background of the enormous growth of the cities in the industrial age and the accompanying social problems, leading European landscape architects in the 20th century like Leberecht Migge (1881-1935), Ernst Cramer (1898-1980), and Dieter Kienast (1945-1998) stated that gardening is neither artistic work nor scientific planning, neither modern nor progressive. Given the respective historical context as well as the particular conception of city and society, this criticism is comprehensible. In the 21st century though, the garden as a living component in the ‘network metropolis’, and gardening itself, especially ‘urban gardening’, were experiencing a remarkable renaissance. Against the background of today’s rapid development of the ‘Zwischenstadt’, it turns out that the basic principles of garden thinking never really lost their relevance.

Designing with Hybridity, Scalar Paradoxes, and Complex Dynamics

description: Belonging to the small-scale and private sphere, gardens are usually omitted from urban and regional landscape plans. Yet, we argue that the assemblage of everyday gardens – the garden complex – is an inherent component of the landscape metropolis that holds the potential to become a powerful landscape agency. This potential is enclosed, among others, within three particular qualities: hybridity, scalar paradoxes, and complex dynamics. Practicing these qualities as concepts for landscape design and analysis helps to expand the imaginaries of everyday gardens to more purposefully reflect and negotiate the condition of the landscape metropolis. By means of two case studies – two domestic gardens – we demonstrate that designing with hybridity entails versatility, simultaneity, and multiplicity, thereby engendering a richness of meaning and experiences. This pluralism is also inherent in the scalar paradoxes we observed. Cross-scalar interactions evoke design implications that transcend the confines of the private plot, surpassing individual, human gain, and making individual gardens enter into dialogue with each other and with their surroundings. Lastly, by working with an enlarged set of complex dynamics, the two case studies prove that a garden can be a driver of change and innovation, and thereby a valuable source of resilience.

description: Type Ia Supernovae (SNe Ia) are the thermonuclear explosion of a carbon-oxygen white dwarf (WD) and are well-known as a distance indicator. However, it is still unclear how WDs increase their mass near the Chandrasekhar limit and how the thermonuclear runaway happens. The observational clues associated with these open questions, such as the photometric data within hours to days since the explosion, are scarce. Thus, an essential way is to discover SNe Ia at specific epochs with optimal surveys. The 2.5-m Wide Field Survey Telescope (WFST) is an upcoming survey facility deployed in western China. In this paper, we assess the detecability of SNe Ia with mock observations of WFST. Followed by the volumetric rate, we generate a spectral series of SNe Ia based on a data-based model and introduce the line-of-sight extinction to calculate the brightness from the observer. By comparing with the detection limit of WFST, which is affected by the observing conditions, we can count the number of SNe Ia discovered by mock WFST observations. We expect that WFST can find more than $3.0\times10^{4}$ pre-maximum SNe Ia within one-year running. In particular, WFST could discover about 45 bright SNe Ia, 99 early-phase SNe Ia, or $1.1\times10^{4}$ well-observed SNe Ia with the hypothesized Wide, Deep, or Medium mode, respectively, suggesting WFST will be an influential facility in time-domain astronomy.

Situated Practice

description: The ground is both the surface occupied by urban development and a physical media – soil – in which plants grow. Since housing density is a mechanism by which to maximise a site’s financial yield, construction covers the real ground. Consequently, the soil is provided to residents in containers on terraces or balconies. However, the properties of natural ground and simulated ground are different, affecting gardening activity and the kind of material and spatial outcomes resulting from it, the synthesis of which is called “the viridic” by the author. Gardening has health benefits for people. Correspondingly, because different soil conditions affect gardening, this benefit’s qualities are also inflected by access to and type of soil. Using Yin’s “theory building” case study model, two gardens by a landscape architect in Girona are discussed: one on a terrace in containers; the other on the natural ground in a public reserve nearby. Comparing and contrasting these gardens allows for the consideration of the relationship between soil and gardening technique. In addition, the process of abstraction of the ground implicit in site development may also be considered, as well as the implications of such a process on the way in which residents cultivate their gardens and the limitations of private gardens in contributing to local microclimatic and environmental qualities. The paper concludes by refining the model of the viridic based on soil and how soil mediates the relationship of the viridic to urban development.

Gardens of Interstitial Wildness

description: This paper looks into ‘gardens of wildness’ that have been established in metropolitan interstitial spaces. These unused, unfunctional urban spaces could be considered as spatial-temporary interstices of the metropolitan landscape. These ‘interstitial spaces’ possess the potential to host diverse social-ecological minorities that tend to be excluded by regulated urban spaces. The ecological qualities of interstitial spaces are recognised by French garden designer Gilles Clément, who regards spontaneous ecologies, which emerge in neglected spaces of the city, as cherished reservoirs that diversify and sustain the urban ecology. Specifically, this paper discusses the value of making gardens of interstitial wildness. If the garden is a potential design approach magnifying the quality of the place, what would be the role of interstitial wild gardens? Furthermore, how do these gardens respond to the relationship between interstitial spaces and the metropolitan landscape? In this paper we will analyse Gilles Clément’s garden design of Jardins du Tiers-Paysage (Gardens of The Third Landscape), located on the roof of the repurposed submarine base of Saint-Nazaire (FR). Reading Saint-Nazaire’s urban context and examining the design from ecological and experiential points of view, this paper shows how the gardens re-introduce the submarine base as a place in the metropolitan landscape of Saint-Nazaire. Orchestrating the experience of the site’s spatial characteristics and the emerging wildness, the gardens elicit an appreciation of the autonomy of non-human agencies and simultaneously reflect upon the heterogeneity of the metropolitan landscape.

description: We develop a first-principles theoretical approach to doping in field-effect devices. The method allows for calculation of the electronic structure as well as complete structural relaxation in field-effect configuration using density-functional theory. We apply our approach to ionic-liquid-based field-effect doping of monolayer, bilayer, and trilayer ZrNCl and analyze in detail the structural changes induced by the electric field. We show that, contrary to what is assumed in previous experimental works, only one ZrNCl layer is electrochemically doped and that this induces large structural changes within the layer. Surprisingly, despite these structural and electronic changes, the density of states at the Fermi energy is independent of the doping. Our findings imply a substantial revision of the phase diagram of electrochemically doped ZrNCl and elucidate crucial differences with superconductivity in Li intercalated bulk ZrNCl.

description: Accurate and fast extraction of lung volumes from computed tomography (CT) scans remains in a great demand in the clinical environment because the available methods fail to provide a generic solution due to wide anatomical variations of lungs and existence of pathologies. Manual annotation, current gold standard, is time consuming and often subject to human bias. On the other hand, current state-of-the-art fully automated lung segmentation methods fail to make their way into the clinical practice due to their inability to efficiently incorporate human input for handling misclassifications and praxis. This paper presents a lung annotation tool for CT images that is interactive, efficient, and robust. The proposed annotation tool produces an "as accurate as possible" initial annotation based on the fuzzy-connectedness image segmentation, followed by efficient manual fixation of the initial extraction if deemed necessary by the practitioner. To provide maximum flexibility to the users, our annotation tool is supported in three major operating systems (Windows, Linux, and the Mac OS X). The quantitative results comparing our free software with commercially available lung segmentation tools show higher degree of consistency and precision of our software with a considerable potential to enhance the performance of routine clinical tasks.

description: Sufficient dimension reduction [J. Amer. Statist. Assoc. 86 (1991) 316-342] has long been a prominent issue in multivariate nonparametric regression analysis. To uncover the central dimension reduction space, we propose in this paper an adaptive composite quantile approach. Compared to existing methods, (1) it requires minimal assumptions and is capable of revealing all dimension reduction directions; (2) it is robust against outliers and (3) it is structure-adaptive, thus more efficient. Asymptotic results are proved and numerical examples are provided, including a real data analysis.

description: Spin-dependent exotic interactions can be generated by exchanging hypothetical bosons, which were introduced to solve some puzzles in physics. Many precision experiments have been performed to search for such interactions, but no confirmed observation has been made. Here, we propose new experiments to search for the exotic spin-spin interactions that can be mediated by axions or Z$^\prime$ bosons. A sensitive functionalized cantilever is utilized as a force sensor to measure the interactions between the spin-polarized electrons in a periodic magnetic source structure and a closed-loop magnetic structure integrated on the cantilever. The source is set to oscillate during data acquisition to modulate the exotic force signal to high harmonics of the oscillating frequency. This helps to suppress the spurious signals at the signal frequency. Different magnetic source structures are designed for different interaction detections. A magnetic stripe structure is designed for Z$^\prime$-mediated interaction, which is insensitive to the detection of axion-mediated interaction. This allows us to measure the coupling constant of both if we assume both exist. With the force sensitivity achievable at low temperature, the proposed experiments are expected to search for the parameter spaces with much smaller coupling constant than the current stringent constraints from micrometer to millimeter range. Specifically, the lower bound of the parameter space will be seven orders of magnitude lower than the stringent constraints for Z$^\prime$-mediated interaction, and an order of magnitude lower for axion-mediated interaction, at the interaction range of $10\, μ$m.

description: The term landscape metropolis and its associated practice of reading the city through the terminology and ‘lens’ of the landscape rather than the normal conventions of urban studies is generally applied to the contemporary city and its expansion beyond the historic centre. Yet, this approach also chimes with the peculiarities of the historic island city and the close relationship such cities have with the restricted, liminal ground on which they are founded. This paper explores the hypothesis that an island city can be understood as a metropolitan landscape as a consequence of peculiarities of geography, ecology, culture, place, and resiliency. By focusing on one such city, Valletta, a heightened case, in which a 16th Century metropolis was founded as Renaissance ‘ideal’, the paper examines the reciprocity between this projected ‘ideal’ and the actual landscape where the metropolis is fused and, indeed, confused with the landscape so that the spatial coherence between city and landscape determines the nature of the metropolis.

the Garden in the Landscape Metropolis

Publisher: name: SPOOL

description: In this issue of SPOOL Landscape Metropolis #6, designerly and discursive work on gardens in the metropolitan landscape is explored. The focus is on the garden as a theatre of landscape in the metropolis, where the city-dweller can stand face to face with natural processes, the longue durée of evolution and natural growth, silence, and open skies, as the counterpart to the excess of the urban programme. This notion of the garden as a theatre, a stage on which landscape and growth are performed, is explored by taking a closer look, spotting those places that merit attention in the vast metropolitan territory. Consequently, this is how we invite our readers to read this issue of SPOOL – by giving attention to the particular, while establishing links between one particularity and another, and to the overarching whole.

description: Qanats have played a vital role in underground water extraction since ancient times based on the community-based water management schemes in Iran. Due to recent urban sprawl and development pressures, qanats are progressively abandoned and degraded in the cities and are considered as endangered assets. To be sustainable, in addition to physical maintenance, the ecological and social aspects of qanat management systems, as the main characteristic of Urban Water Infrastructures in Iran, also need to be taken into account. A review of the traditional participatory management systems in Iran, as well as the contemporary community-based interventions (CBI) in the context of qanats, demonstrates the significant role of public participation in this regard. This research aims to provide solutions and recommendations for enhancement of stakeholder engagement in contemporary qanat rehabilitation practices by adapting the traditional communal management techniques and multi-stakeholder approaches to qanat maintenance in Iran. For this purpose, the transformation of the key urban water stakeholders from past to present are studied and mapped based on their roles and influence on decision making process for the management of qanats. The resulting illustration of the stakeholders’ networks and the comparative study of inter-relationships not only reveals today’s institutional gaps and missing links in qanats’ management procedures, but also highlights the former community-based coordination mechanisms that used to support the smooth functioning of this socio-technical infrastructure by promoting constructive interactions among conflicting parties. In order to tackle contemporary governance challenges, this research also provides a set of practical recommendations to adjust those traditional learnings to new conditions by addressing the physical, environmental, and socio-cultural aspects of qanats in Tehran.

description: We take some parts of a theoretical mobility model in a two-dimension grid proposed by Greenlaw and Kantabutra to be our model. The model has eight necessary factors that we commonly use in a mobile wireless network: sources or wireless signal providers, the directions that a source can move, users or mobile devices, the given directions which define a user's movement, the given directions which define a source's movement, source's velocity, source's coverage, and obstacles. However, we include only the sources, source's coverage, and the obstacles in our model. We define Square Grid Points Coverage (SGPC) problem to minimize number of sources with coverage radius of one to cover a square grid point size of p with the restriction that all the sources must be communicable and proof that SGPC is in NP-complete class. We also give an Approx-Square-Grid-Coverage (ASGC) algorithm to compute the approximate solution of SGPC. ASGC uses the rule that any number can be obtained from the addition of 3, 4 and 5 and then combines 3-gadgets, 4-gadgets and 5-gadgets to specify the position of sources to cover a square grid point size of p. We find that the algorithm achieves an approximation ratio of . Moreover, we state about the extension usage of our algorithm and show some examples. We show that if we use ASGC on a square grid size of p and if sources can be moved, the area under the square grid can be covered in eight-time-steps movement. We also prove that if we extend our source coverage radius to 1.59, without any movement the area under the square gird will also be covered. Further studies are also discussed and a list of some tentative problems is given in the conclusion.

Oslo Hydropolis

description: Oslo Hydropolis is a running landscape and urbanism design studio at the Oslo School of Architecture and Design that investigates how water can play a socially, ecologically, and economically active role in shaping life in the Oslo region. Historically a water-rich area, weather extremes and seasonal abnormalities question the functionality of cultural landscapes in the Oslo region, which is characterised by rain-fed agriculture in the soils of limited valley areas. Excess and scarcity of water—flood and drought—are exacerbated by the uncertainty of climate change, but even more so by the effects of urbanisation. Population in the Oslo region is growing and new models of how water, urbanisation, and social life integrate have to be defined.

description: We present VI-band photometry for stars in the metal-rich globular cluster NGC 6496. Our time-series data were cadenced to search for long period variables (LPVs) over a span of nearly two years, and our variability search yielded the discovery of thirteen new variable stars, of which six are LPVs, two are suspected LPVs, and five are short period eclipsing binaries. An additional star was found in the ASAS database, and we clarify its type and period. We argue that all of the eclipsing binaries are field stars, while 5-6 of the LPVs are members of NGC 6496. We compare the period-luminosity distribution of these LPVs with those of LPVs in the Large Magellanic Cloud and 47 Tucanae, and with theoretical pulsation models. We also present a VI color magnitude diagram, display the evolutionary states of the variables, and match isochrones to determine a reddening of E(B-V) ~ 0.21 mag and apparent distance modulus of ~ 15.60 mag.
