description: Spong3D is an adaptive 3D printed facade system that integrates multiple functions to optimize thermal performances according to the different environmental conditions throughout the year. The proposed system incorporates air cavities to provide thermal insulation and a movable liquid (water plus additives) to provide heat storage where and whenever needed. The air cavities have various dimensions and are located in the inner part of the system. The movable liquid provides heat storage as it flows through channels located along the outer surfaces of the system (on the indoor and outdoor faces of the façade). Together, the composition of the channels and the cavities form a complex structure, integrating multiple functions into a singular component, which can only be produced by using an Additive Manufacturing (AM; like 3D printing) technology.

description: Motivated by the Galactic Center gamma-ray excess in the Fermi-LAT data, we study the signatures of a class of tau portal dark matter (DM) models where DM particles preferentially couple to tau leptons at the LHC. We consider the constraints from the DM direct detection and investigate the sensitivity of the LHC to di-tau plus missing energy signatures. We find that the LHC with a high luminosity of 3000 fb$^{-1}$ can test the tau portal DM models with fermionic mediators in the mass range of $120\sim450$ GeV.

Gothenborg’s Jublieumsparken 0.5 and Frihamnen: explorations into the aesthetic of DIY
Creators: name: Dahl, Caroline
Publisher: name: SPOOL
Year: 2016

description: This design critique explores how a top-down approach of conventional planning coincides with a do-it-(y)ourself project that evolved from the site and is facilitated by a designated mediator working within in city administration with the purpose of bridging the city’s disconnected departments. Hence, the project called Jubileumsparken 0.5 was instigated in 2013 as a place making project in concurrence with urban planning undertakings in order to facilitate a redevelopment of the harbour area of Frihamnen in Gothenburg, Sweden. The purpose of this ongoing project is to make use of the intervening period to explore the site and its specific qualities and relationships, and to test these through prototypes and events before plans and protocols are set in stone. Only three years later, at a point when this specific time period is starting to run out and the first development plans are being drafted, this article demonstrates – through a transformation analysis – that the abandoned site has been turned into a particular place through people’s engagement and the processes of building together. Furthermore, it shows that the embedded narratives of these actions are starting to challenge the planners' otherwise distant and abstract understanding of this place.

description: The stability of eight nominal fictitious Uranus Trojan orbits over the age of the Solar system has been measured. The initial inclinations, i0, were 0 deg., 5 deg., 15 deg., and 30 deg. relative to the ecliptic plane. Initial eccentricities ranged from 0 to 0.1 for i0 = 0 deg., 5 deg., and 0 to 0.2 for i0 = 15 deg., 30 deg. Half of the orbits were in the L4 swarm, and half were in the L5 swarm. Orbits in the L4 swarm had mean longitudes 8.8 deg. from the nominal L4 Lagrange point, and orbits in the L5 swarm had mean longitudes 18.2 deg. from the nominal L5 point. I integrated 10,000 massless clones per nominal orbit in the six-body problem (Sun, test particle, four giant planets) for 4.5 Gyr and calculated the half-life for each orbit. A total of 1291 test particles survived for the entire integration time. Of these survivors, 99% were associated with the nominal orbit with i0 = 0 deg. in the L4 swarm. These surviving test particles had initial eccentricities in the range e0 < 0.07. The half-lives associated with L4 orbits were 1258 Myr, 286 Myr, 56 Myr, and 237 Myr for nominal orbits with i0 = 0 deg., 5 deg., 15 deg., and 30 deg., respectively. The half-lives associated with L5 orbits were 103 Myr, 281 Myr, 25 Myr, and 46 Myr, respectively. The overall results showed that the ecliptic plane is one good place to search for primordial Uranus Trojans.
Emergence of string-like physics from Lorentz invariance in loop quantum gravity

description: We consider a quantum field theory on a spherically symmetric quantum space time described by loop quantum gravity. The spin network description of space time in such a theory leads to equations for the quantum field that are discrete. We show that to avoid significant violations of Lorentz invariance one needs to consider specific non-local interactions in the quantum field theory similar to those that appear in string theory. This is the first sign that loop quantum gravity places restrictions on the type of matter considered, and points to a connection with string theory physics.

Unfamiliar territory: alternative landscape reading of disturbed sites’ particularities
Creators: name: Prezelj, Barbara
Publisher: name: SPOOL
Year: 2016

description: In an age when it is becoming increasingly apparent that disturbed sites (or any other sites for that matter) can never be fully managed, nor can their future development be entirely predetermined, this paper looks at disturbed sites’ landscape as a complex and metastable system. While it deals with disturbed sites in particular, more broadly it aims to encourage a general re-examination of landscape design that relies on the world in harmonious balance and the experience of visual pleasure, which, according to long-established structures, may please or offer timeless experiences but in most cases hold little power and no potential to change, enhance or diminish (our own) bodily capacities to act – to stimulate thought, influence ideas, judgements and desires. In order to explore ways of moving away from the desire for a stable portrayal of ‘the natural’ that often motivates disturbed sites’ immediate ecological remediation and later programmatic transformation, the paper firstly, in order to clarify the understanding of the proposed alternative, imagines landscapes where such an approach is driven to extreme. Next, it places focus on the concept of territory and through the processes behind territory-making argues for a rethinking of the common ways of reading, intervening in and representing complex (in this case disturbed) sites. Alongside this, it proposes a reinterpretation of the notion of place, presents an alternative search for ‘the specific’ and questions what could specificity, once cleared of any ‘essence’, actually stand for. Ideas and concepts developed throughout this paper begin with writings on territory by Deleuze and Guattari on one side, with further elaborations by Bogue, Brighenti, Grosz, and others. On the other side, ideas of post-humanism and new materialism provide a new view on disturbed sites to broaden the conception of territory as a relational, process-driven and open-ended mode of organization. They are accompanied by diagrammatic mappings that describe and analyse a very particular place – Fort de Vaujours, an abandoned uranium-contaminated site near Paris.

The role of durational art strategies in urban regeneration in Budapest
Creators: name: Tihanyi, Dominika
Publisher: name: SPOOL
Year: 2016

description: The presented strategy reflects on the theme of sustainable urban regeneration, focusing on the importance of the role of public spaces in creating liveable cities. The theoretical background of the strategy deals with the changes taking place in the fields of public art and urban rehabilitation methodologies. The parallel drawn between the evolvement of the two fields leads to the introduction of a method which integrates public art interventions into the process of urban rehabilitation. Public art interventions become platforms that enable people to take an active role in creating and forming their future, and enable future landscape/public space design elements to become more site-specific and unique.

description: The interaction between surface acoustic waves (SAWs) and spin waves (SWs) in a piezoelectric/magnetic thin film heterostructure yields potential for the realization of novel microwave devices and applications in magnonics. In the present work, we investigate the SAW-SW interaction in a Pt/Co(2 nm)/Ru(0.85 nm)/Co(4 nm)/Pt synthetic antiferromagnet (SAF) composed of two ferromagnetic layers with different thicknesses separated by a thin nonmagnetic Ru spacer layer. Because of the combined presence of interfacial Dzyaloshinskii--Moriya interaction (iDMI) and interlayer dipolar coupling fields, the optical SW mode shows a large nondegenerate dispersion relation for oppositely propagating SWs. Due to SAW-SW interaction, we observe nonreciprocal SAW transmission in the piezoelectric/SAF hybrid device. The equilibrium magnetization directions of both Co layers are manipulated by an external magnetic field to set a ferromagnetic, canted, or antiferromagnetic configuration. This has a strong impact on the SW dispersion, its nonreciprocity, and SAW-SW interaction. The experimental results are in agreement with a phenomenological SAW-SW interaction model, which considers the interlayer exchange coupling, iDMI, and interlayer dipolar coupling fields of the SWs.

description: We show how the conic hull method, recently developed for the analytic and non-iterative evaluation of multifold Mellin-Barnes (MB) integrals, can be extended to the case where these integrals have straight contours of integration parallel to the imaginary axes in the complex planes of the integration variables. MB integrals of this class appear, for instance, when one computes the $ε$-expansion of dimensionally regularized Feynman integrals, as a result of the application of one of the two main strategies (called A and B in the literature) used to resolve the singularities in $ε$ of MB representations. We upgrade the Mathematica package MBConicHulls.wl which can now be used to obtain multivariable series representations of multifold MB integrals with arbitrary straight contours, providing an efficient tool for the automatic computation of such integrals. This new feature of the package is presented, along with an example of application by calculating the $ε$-expansion of the dimensionally regularized massless one-loop pentagon integral in general kinematics and $D=4-2ε$.

description: We performed a first-principles study of the structural, vibrational, electronic and magnetic properties of NaMnF3 under applied isotropic pressure. We found that NaMnF3 undergoes a reconstructive phase transition at 8 GPa from the Pnma distorted perovskite structure toward the Cmcm post-perovskite structure. This is confirmed by a sudden change of the Mn-F-Mn bondings where the crystal goes from corner shared octahedra in the Pnma phase to edge shared octahedra in the Cmcm phase. The magnetic ordering also changes from a G-type antiferromagnetic ordering in the Pnma phase to a C-type antiferromagnetic ordering in the Cmcm phase. Interestingly, we found that the high-spin d-orbital filling is kept at the phase transition which has never been observed in the known magnetic post-perovskite structures. We also found a highly non-collinear magnetic ordering in the Cmcm post-perovskite phase that drives a large ferromagnetic canting of the spins. We discuss the validity of these results with respect to the U and J parameter of the GGA+U exchange correlation functional used in our study and conclude that large spin canting is a promising property of the post-perovskite fluoride compounds.

A story of three: a narrative approach to reading atmosphere and making place

Publisher: name: SPOOL
Year: 2016

description: This article explores a site-specific, narrative approach to placemaking in order to reveal ways of reading and reacting to spatial atmospheres. The contribution presents an MSc Architecture project that results in the design of three particular places on the fringes of the Dutch urban landscape by means of utilizing a narrative approach to reading and analysing the existing site-specific atmospheres. The three architectural follies designed within the landscape present opportunities for the insertion of narrative through experience, illuminating the contents within the existing context. The intention of the project was to explore how an architectural installation could serve as a locus for the generation of new trajectories of perception and understanding. Through a sequencing of events within each landscape folly, the existing site is revealed to the reader in a new way, establishing new circumstances to engage with the landscape. The implementation of narrative within the processes of placemaking allowed for the overlay of subjective interpretations through personal experience, creating spaces saturated with personal signification and interpretation. The three projects demonstrate the necessity of freedom of imagination and interpretation in placemaking and how a narrative approach to design can allow one to be fully involved in the creation of personal and particular place.

description: This paper addresses the question of whether Witten's proof of positive ADM energy for classical general relativity can be extended to give a proof of positive energy for a non-perturbative quantization of general relativity. To address this question, a set of conditions is shown to be sufficient for showing the positivity of a Hamiltonian operator corresponding to the ADM energy. One of these conditions is a particular factor ordering for the constraints of general relativity, in a representation where the states are functionals of the Ashtekar connection, and the auxiliary, Witten spinor. These developments are partly based on results derived with Artem Starodubtsev (unpublished notes, 2004).

description: The super-Brownian motion Xϱ in a catalytic medium ϱ constructed in [DF96a] is known to be persistent (no loss of expected mass in the longtime behaviour) in dimensions one ([DF96a]) and three ([DF96b]). Here we fill the gap in showing that persistence holds also in the critical dimension two. The key to this result is that in any dimension (d ≤ 3), given the catalyst, the variance of the process is finite 'uniformly in time'. This is in contrast to the 'classical' super-Brownian motion where this holds only in high dimensions (d ≥3), whereas in low dimensions the variances grow without bound, and the process clusters leading to local extinction.
Providing a stage for atmospheric encounters: Brattøra’s seafront by SLA
Creators: name: Labadini, Alice
Publisher: name: SPOOL
Year: 2016

description: The article addresses the theme of ‘particular places’ in the contemporary landscape metropolis by focusing on the temporal, climatic and geographic specificity that determines each place as unique. In particular, it explores how design can support the appreciation of a ‘particular place’ by enhancing the readability of its temporal, climatic and geographic constituents through an engagement with local weather phenomena. The article considers the capacity of design to foreground the particularity of a place by connecting to its weather through a critical reading of SLA’s redesign of the seafront of Brattøra in the city of Trondheim in Norway. My critical approach to the project juxtaposes a personal investigation of the design work based on primary experience and the insights of a conversation with SLA’s principal Stig Lennart Andersson, performed and transcribed in 2012 as part of my doctoral thesis. Elaborating on this conversation, the article is articulated in three successive thematic sections, dealing respectively with the concepts of ground, exposure and wonder. Albeit specific to the project, these notions afford the possibility to expand upon more universal considerations of the capacity of design to foreground diffuse, changing and immaterial components of space in human experience. In the conclusive part of the article, I attempt to verbalise why SLA’s work can be considered a valuable reference for the design of ‘particular places’ in the contemporary landscape metropolis.

description: In the present work, we perform systematic estimations for the radiative decays of the charmed mesons in a modified relativistic quark model. Our estimations indicate that the branching ratios of the process of $D_2^0(1^3P_2) \to D^{\ast 0}(1^3S_1) γ$, $D_3^0(1D_3) \to D_2^0(1^3P_2) γ$, $D_2^0(2D_2^\prime) \to D_1^{0}(2P_1) γ$, $D_3^0(2^3D_3) \to D_2^0(2^3P_2) γ$, and $D^{\ast 0}(1^3S_1) \to D^0(1^1S_0) γ$ are of the order of $10^{-2}$, which are sizable to be detected experimentally. Moreover, the branching ratios of some channels, for example, $D_1^0(1P_1) \to D(1^1S_0)^0 γ$, $D^0(3^1S_0) \to D_1^{\prime 0}(2P^\prime_{1}) γ$ and $D^0(3^3S_1) \to D_2^0(2^3P_2) γ$ are estimated to be of the order of $10^{-3}$, which may be accessible with the accumulation of data in future experiments.

Practicing design for particular places
Creators: name: De Wit, Saskia
name: Diedrich, Lisa
Publisher: name: SPOOL
Year: 2016

description: Since its first issue, SPOOL has used the term ‘landscape metropolis’ to address urban formations beyond the traditional city that – despite their increasing ubiquity - still lack in-depth attention from the perspective of aesthetic appreciation, designerly concepts of development, guidelines for planning and governance, and design theoretical apprehension. The prefix ‘landscape’ is used to describe attention to these topics through the lens of landscape architecture, and offers, we feel, some novel potentials: in considering the metropolis as a cultural phenomenon that is constructed mentally as well as physically and socially; which relies on human as well as on natural driving forces; and which contains, somewhere in the cracks of the mosaic, in the ‘in-between’, places with distinguishable qualities – particular places.

‘Yes We Camp!’: Marseille’s artistic and participatory urban camp examined through a socio-materiality lens
Creators: name: Siarheyeva, Alena
Publisher: name: SPOOL
Year: 2016

description: The presented paper builds on theoretical language borrowed from post-modern philosophy and humanist geography to investigate particular features of the artistic and participatory “Yes We Camp!” The article emphasizes a mutually reinforcing relationship between static properties of the site – its spatial organization, built environment and selection of materials – and its dynamic characteristics – social interactions, organizational form and the emotional resonance evoked in people. The paper shows that place particularity is symbolically conveyed by the spatial organization and built environment and is collectively lived and felt as a unique atmosphere. Thus, our understanding of particular places cannot be complete without accounting for the complex interactions between their spatial, material, social and human dimensions.

Isotopic ratio, isotonic ratio, isobaric ratio and Shannon information uncertainty

Subjects: subject: Nuclear Theory (nucl-th)

description: The isoscaling and the isobaric yield ratio difference (IBD) probes, which both are constructed by yield ratio of fragment, provide cancelation of parameters. The information entropy theory is introduced to explain the physical meaning of the isoscaling and IBD probes. The similarity between the isoscaling and IBD results is found, i.e., the information uncertainty determined by the IBD method equals to $β-α$ determined by the isoscaling [$α$ ($β$) is the parameter fitted from the isotopic (isotonic) yield ratio].

description: The purpose of this paper is to address the question of whether or not there exists a linear space of initial data generating global in time solutions of the initial-boundary value problem for 3-dimensional Navier-Stokes equations (3D NSE), and to establish unconditional results about global attractors for 3D NSE by bypassing the problem of uniqueness and global regularity. For this goal, the author introduces the notion of energetic system which is capable of both incorporating 3D NSE and adequate modelling of properties of 3D NSE.

The invariance of asymptotic laws of stochastic systems under discretization

subject: 65U05

description: The stochastic trapezoidal rule provides the only discretization scheme from the family of implicit Euler methods (see [11]) which possesses the same asymptotic (stationary) law as underlying linear continuous time stochastic systems with white or coloured noise. This identity is shown for systems with multiplicative (para- metric) and additive noise using fixed point principles and the theory of positive operators. The key result is useful for adequate implementation of stochastic algorithms applied to numerical solution of autonomous stochastic differential equations. In particular it has practical importance when accurate long time integration is required such as in the process of estimation of Lyapunov exponents or stationary measures for oscillators in Mechanical Engineering.

Ion energy scaling under optimum conditions of laser plasma acceleration

description: A new, maximum proton energy, $e$, scaling law with the laser pulse energy, $E_L$ has been derived from the results of 3D particle-in-cell (PIC) simulations. Utilizing numerical modelling, protons are accelerated during interactions of the femtosecond relativistic laser pulses with the plain semi-transparent targets of optimum thickness [Esirkepov {\it et al.} Phys. Rev. Lett. {\bf 96}, 105001 (2206)]. The scaling, $e \sim E_L^{0.7}$, has been obtained for the wide range of laser energies, different spot sizes, and laser pulse durations. Our results show that the proper selection of foil target optimum thicknesses, results in a very promising increase of the ion energy with the laser intensity even in the range of parameters below the radiation pressure (light sail) regime. The proposed analytical model is consistent with numerical simulations.
Frame and framing: a theory-based investigation into frame as an instrument for landscape architecture
Creators: name: Alexandrescu, Maria
Publisher: name: SPOOL
Year: 2016

description: In this paper, I introduce the concept of the frame. The mechanisms of framing are a strategic and conceptual tool for dealing with the complexities of place in terms of site specificity. Starting from both a theoretical understanding of the frame in terms of what it does rather than what it is, and from a specific site — the territory surrounding the Palace of the Parliament in Bucharest, Romania — I investigate ways of working with a contested territory in a site specific, open-ended way. As the locus of a large-scale urban project for a new civic centre initiated in 1984 by Ceausescu and interrupted by the revolution of 1989, this territory is fixed in both scale and determination. The mechanisms of framing provide the starting point for rethinking the site through framing, in order to uncover, draw out, and reconfigure its specificities, providing a structure for a wide range of place-making practices to unfold.

Automatic control via thermostats of a hyperbolic Stefan problem with memory

description: A hyperbolic Stefan problem based on the linearized Gurtin-Pipkin heat conduction law is considered. Temperature and free boundary are controlled by a thermostat acting on the boundary. This feedback control is based on temperature measurements performed by real thermal sensors located into the domain containing the two-phase system and/or at its boundary. Three different types of thermostats are analyzed: ideal switch, relay switch, and Preisach hysteresis operator. The resulting models lead to formulate integrodifferential hyperbolic Stefan problems with nonlinear and nonlocal boundary conditions. In all the cases, existence results are proved. Uniqueness is also shown, unless in the situation corresponding to the ideal switch.
