description: We apply a general first-principles approach to derive the phase diagram of metallic Lithium at ambient pressure between 0 and 350 K, including identification of candidate phases. We use ab initio random structure searching (AIRSS) to identify competing phases and supplement the results with calculations of vibrational properties and relevant derived neutron diffraction patterns. Strong quantum nuclear effects are present, prompting a careful treatment of vibrations. We directly map the Born-Oppenheimer surface of Li for the first time, allowing the extension of the normal quasi-harmonic treatment of vibrations to a "quasi-anharmonic" approach, where the effects of anharmonicity are included. The Gibbs free energies of the FCC, BCC, HCP and 9R phases are derived using a variety of equations of state. We find that the anharmonic contribution to the Gibbs free energies of Li phases is of the same order as the differences between phases. Anharmonicity also makes a noticeable difference to the 0 K phonon dispersion of the BCC phase, with the largest difference at the N-point phonon. The ordering of phase transitions that we find agrees with the calculations of Ackland et al. [Science 356, 1254-1259, (2017)], even when anharmonic effects are included, suggesting that a quasi-harmonic treatment is sufficient for correct phase behaviour. We show explicitly that the Martensitic phase transition from close-packed to BCC lithium upon heating is driven by entropic contributions to the phonon free energy.

description: In a porous rock, the spatial distribution of the pore space induces a strong heterogeneity in fluid flow rates and in the stress distribution in the rock mass. If the rock microstructure evolves through time, for example by dissolution, fluid flow and stress will evolve accordingly. Here, we consider a core sample of porous limestone that has undergone several steps of dissolution. Based on 3D X-ray tomography scans, we calculate numerically the coupled system of fluid flow in the pore space and stress in the solid. We determine how the flow field affects the stress distribution both at the pore wall surface and in the bulk of the solid matrix. We show that, during dissolution, the heterogeneous stress evolves in a self-similar manner as the porosity is increased. Conversely, the fluid velocity shows a stretched exponential distribution. The scalings of these common master distributions offer a unified description of the porosity evolution, pore flow, and the heterogeneity in stress for a rock with evolving microstructure. Moreover, the probability density functions of stress invariants (mechanical pressure or von Mises stress) display heavy tails towards large stresses. If these results can be extended to other kinds of rocks, they provide an additional explanation of the sensitivity to failure of porous rocks under slight changes of stress.

description: The aim of this paper is to define and isolate the drivers of speculative cash hoarding phenomena in publicly traded non-financial American firms before and after the financial crisis of 2008. The model presented in this paper uses previous literature defined drivers of transaction and precautionary motives for holding cash as control variables, and introduces new measures for market endorsement and economic conditions, that were never used before in this context. Empirical results show that cash accumulation is prominent among profitable firms, and that cash accumulation in excess of ongoing and precautionary needs of companies was endorsed by the financial markets both before and after the financial crisis of 2008. Results also support previous findings that financially unconstrained firms have a lesser need for market endorsement for cash hoarding. The contribution of this paper to the body of literature related to cash management and cash hoarding is five-fold: (i) it provides empirical evidence of market-endorsed cash hoarding in the US non-financial companies; (ii) it extends the existing models of transaction-related cash holdings to include, formally define and test the drivers of precautionary cash accumulation in the non-financial sector; (iii) it formally defines and tests a metric for market sentiment related to cash hoarding before and after the financial crisis of 2008; (iv) provides empirical evidence that the crisis of 2008 was anticipated by the corporate sector as early as 2005, and recovery from the crisis was predicted as early as Q2:08; and (v) defines and quantifies the border separating the precautionary and speculative motives for cash accumulation.

description: First proclaimed an amazing innovation, now plastic permeates everything—our homes, food, earth, oceans, many living creatures, including ourselves. The use of plastic is problematic, but hard to change. It is culturally situated, commercially embedded, learned, ingrained, often automatic. And, while alternatives are available, they can be hard to find and more expensive than their plastic counterparts. To engage with this issue, we undertook a design-based investigation of DIY bioplastic, edible and hyper-compostable tableware. Our aim was to render such alternatives more accessible. DIY recipes are available online. Yet, often lack vital information to make their use easy. We discovered how to ‘tame’ fabrication of plastic alternatives by adding information about cooking and curing to the recipes. Our experiments suggest that ‘at home’ production of bioplastics and the accompanying re-design of cutlery and table- ware, engender new, more sustainable, eating habits by—literally—designing new ways of eating. They also afford reframing of food ‘waste’ into material resource. We present a hand-made book and mate- rial sample set that make our findings tangible and accessible to design researchers, amateur gastronomists, DIY enthusiasts, and others curious about plastic alternatives. Our findings support a move of scientific practices from the lab to people’s homes.

description: The Soma Bits are a prototyping toolkit that facilitates Soma Design. Acting as an accessible ‘sociodigital material’ Soma Bits allow designers to pair digital technologies, with their whole body and senses, as part of an iterative soma design process. The Soma Bits addresses the difficulty we experienced in past Soma Design processes — that articulating of sensations we want to evoke to others, and then maintaining these experiences in memory throughout a design process. Thus, the Soma Bits enable designers to know and experience what a design might ‘feel like’ and to share that with others.
The Soma Bits relate to three experiential qualities: ‘feeling connected’, ‘feeling embraced’, and ‘being in correspondence’ with the interactive materials. The Soma Bits have a form factor and materiality that allow actuators (heat, vibration, and shape-changing) to be placed on and around the body; they are easily configurable to enable quick and controllable creations of soma experiences which can be both part of a first-person approach as well as shared with others. The Soma Bits are a living, growing library of shapes and actuators. We use them in our own design practices, as well as when engaging others in soma design processes.

description: In various fields, statistical models of interest are analytically intractable. As a result, statistical inference is greatly hampered by computational constraints. However, given a model, different users with different data are likely to perform similar computations. Computations done by one user are potentially useful for other users with different data sets. We propose a pooling of resources across researchers to capitalize on this. More specifically, we preemptively chart out the entire space of possible model outcomes in a prepaid database. Using advanced interpolation techniques, any individual estimation problem can now be solved on the spot. The prepaid method can easily accommodate different priors as well as constraints on the parameters. We created prepaid databases for three challenging models and demonstrate how they can be distributed through an online parameter estimation service. Our method outperforms state-of-the-art estimation techniques in both speed (with a 23,000 to 100,000-fold speed up) and accuracy, and is able to handle previously quasi inestimable models.

description: We have performed detailed first-principles calculations to determine the eigenvectors of the zone-center modes of hexagonal BaTiO3 and shown that the experimentally relevant low-energy modes (including the non-polar instability) can be represented as suitable combinations of basic local polar distortions associated with the instability of the cubic perovskite phase. The hexagonal structure provides a testing ground for the analysis of the influence of the stacking of TiO6 octahedra: the occurrence of relatively high-energy chains of dipoles highlights the importance of local effects related to the coherent hybridization enhancement between Ti and O ions. Our results provide simple heuristic rules that could be useful for the analysis of related compounds.

Starting with a parent cuprate as an analogue of the quantum paramagnet ground state and using the Schwinger boson technique we found the pseudospin spectrum and conditions for the pseudomagnon condensation with phase transition to a superconducting state.

description: ‘A Measurable Factor Sets the Conditions of its Operation’ is an on-going research project and series of publicly exhibited materials originally developed through the Stanley Picker Research Fellowship at Kingston University. This paper outlines the method, process and contextual underpinnings of the project, which aims to rethink the ways in which shoes are designed by shirking traditional approaches. It instead employs an engineering method based on structural parameters, informed by biomechanical factors, required to support a high-heeled foot while in motion.
Through continuous critical reflection on the method as it was being developed, I identified areas of study necessary to understand and unpick the gendered connotations of the high-heeled shoe, which in turn informed the artistic framing of the project and additional filmic work. In so doing the work expands on the discourse surrounding high-heeled shoes and the gendering of different disciplines and objects.
Atomic photoionization cross-sections beyond the electric dipole approximation

description: A methodology is developed to compute photoionization cross-sections beyond the electric dipole (BED) approximation from response theory, using Gaussian type orbitals and plane waves for the initial and final states, respectively. The methodology is applied to compute photoionization cross-sections of atoms and ions from the first four rows of the Periodic Table. Analysing the error due to the plane wave description of the photoelectron, we find kinetic energy and concomitant photon energy thresholds above which the plane wave approximation becomes applicable. The correction introduced by going beyond the electric dipole approximation increases with photon energy and depends on the spatial extension of the initial state. In general, the corrections are below 10% for most elements, at a photon energy reaching up to 12 keV.

description: Two-dimensional (2D) XY model subject to three different types of dynamics, namely Monte Carlo, resistivity shunted junction (RSJ), and relaxational dynamics, is numerically simulated. From the comparisons of the current-voltage (I-V) characteristics, it is found that up to some constants I-V curves at a given temperature are identical to each other in a broad range of external currents. Simulations of the Villain model and the modified 2D XY model allowing stronger thermal vortex fluctuations are also performed with RSJ type of dynamics. The finite-size scaling suggested in Medvedyeva et al. [Phys. Rev. B 62, 14531(2000)] is confirmed for all dynamic models used, implying that this finite-size scaling behaviors in the vicinity of the Kosterlitz-Thouless transition are quite robust.

Excitation spectrum of the S=1/2 quantum spin ladder with frustration: elementary quasiparticles and many-particle bound states

description: We study the excitation spectrum of the two-chain S=1/2 Heisenberg spin ladder with additional inter-chain second-neighbor frustrating interactions. The one and two-particle excitations are analyzed by using a mapping of the model onto a Bose gas of hard-core triplets. We find that low-lying singlet and triplet two-particle bound states are present and their binding energy increases with increasing frustration. In addition, many-particle bound states are found by a combination of variational and exact diagonalization techniques. We prove that the larger the number of bound quasiparticles the larger the binding energy. Thus the excitation spectrum has a complex structure and consists of elementary triplets and collective many-particle singlet and triplet excitations which generally mix with the elementary ones. The model exhibits a quantum phase transition from an antiferromagnetic ladder phase (small frustration) into Haldane phase (effectively ferromagnetic ladder for large frustration). We argue that near the transition point the spectrum in both triplet and singlet channels becomes gapless. The excitation wave function is dominated by large-size bound states which leads to the vanishing of the quasiparticle residue.

description: We study the inclusive production of the next-to-lightest neutralino chi2, decaying directly, or via slepton, into two leptons and the lightest neutralino. The dilepton invariant mass spectrum in these decays has a characteristic sharp edge near the kinematical upper limit. We propose to exploit this feature as a search strategy for the chi2, and thereby for SUSY. The possibilities to determine neutralinos and slepton masses are also discussed.

description: Das Älterwerden und der Lebensabschnitt rund um die Pensionierung sind aktuelle Themen, die im gesellschaftspolitischen Diskurs an Relevanz gewinnen. Dabei entsteht die Frage, wie sich der Ausstieg aus dem Erwerbsleben auf das Individuum auswirkt und welche psychosozialen Veränderungen dabei entstehen. In vorliegender Bachelorarbeit gehen die Autorinnen Aisha Kashemwa, Nadine Krüsi und Anna Ribaux dieser Frage nach. Im Fokus der qualitativen Forschung stehen acht Frauen mit ihren individuellen Erfahrungen im Übergang in die Pension. Gesellschaftliche Rahmenbedingungen stellen neupensionierte Frauen vor vielfältige, psychosoziale Veränderungen, welche für sie teilweise Herausforderungen darstellen. Aus einem ressourcenorientierten Blickwinkel betrachtet sind die Autorinnen überzeugt, dass diese Veränderungen auch Chancen mit sich bringen. Diesbezüglich beleuchten sie in vorliegender Arbeit die individuellen Bedürfnisse von Frauen im Übergangsprozess in die Pension und leiten Handlungsfelder und Handlungsbedarfe für die Soziale Arbeit ab. Es wird ersichtlich, dass eine Auseinandersetzung mit der Thematik der Pensionierung sowie die Sensibilisierung dafür gefördert werden müssen, um der Stigmatisierung älterer Menschen entgegenzuwirken. Diese verfügen über Ressourcen und Potenziale, welche nur dadurch optimal erkannt und genutzt werden können. Die Autorinnen regen mit dieser Arbeit dazu an, dass sich Professionelle, vor allem der Sozialarbeit und der Soziokulturellen Animation, vermehrt mit dem Alter(n) und der Pensionierung auseinandersetzen und die Bedürfnisse dieser Zielgruppe in ihrem Planen und Handeln miteinbeziehen.

A particular scaling is used in the equation, which permits to evaluate the wave-function normalization after the numerical solution. We have a two point boundary value problem, where the second point is taken at infinity. The differential equation is solved using the shooting method and Runge-Kutta integration method, requiring that the asymptotic constants, for the function and its derivative, are equal for large distances. In order to obtain fast convergence, the secant method is used.

Der Workshop „Bildethik – zum Umgang mit Bildern im Internet“ wollte genau hier ansetzen und einen Austausch von Erfahrungen, Methoden und Strategien im Umgang initiieren.
The social production of inequity: an exploration of resident stress and neighborhood change in Jersey City
Creators: name: Dunn, Lisa B.
Publisher: name: No Publisher Supplied
Year: 2021

description: Problem Statement: Cumulative stress often marks those whose lifetimes are shaped by oppression and the impacts of structural violence. This study explored the complex intersection of gentrification, public policy and property reevaluation in Berry Hill, a neighborhood in Jersey City’s F Ward. A recent reevaluation of property value and subsequent tax changes has made the neighborhood even more vulnerable to a recreation of inequity. To date, no studies have analyzed how residents interpret stress related to gentrification in the context of a property revaluation or assessed its human impacts. Methodology: A multi-method qualitative single-case study design was chosen for the study. The research questions were as follows: RQ1. How does Jersey City’s history of displacement relate to current inequities?; RQ2a. To what extent is property revaluation viewed as a form of gentrification by Berry Hill residents?; RQ2b. How do residents view development projects in the Berry Hill neighborhood related to their housing security?; RQ2c. What opinions do residents hold about changes in neighborhood demographics?; RQ3a. What types of significant experiences do Berry Hill residents identify across their lifetimes related to living in the neighborhood?:RQ3b.Do residents view any/all of these experiences as stressors?; 4a property revaluation impacted Berry Hill residents?; and RQ4b. Do residents identify any other public policies that they feel contribute to stress in their lives or to covert racism in the neighborhood?Twenty-one semi-structured interviews were conducted with Berry Hill residents. Results: Four themes emerged from the study: Theme 1, "History Repeats Itself", Theme 2, "Everyday Life," Theme 3, "Blatant Racism and Oppression," and Theme 4, "Physical and Mental Health." Together, these themes convey residents’ insights about stressors in the Berry Hill neighborhood, as well as some of their health implications. Conclusion: Berry Hill is in a state of mixing, a stage of the gentrification process in which both longtime and newly arrived residents inhabit the neighborhood. The process represents the culmination of cyclic historic stressors which lead to the displacement of longtime neighborhood residents, increasing their risk of physical and mental health issues. Yet, despite the adverse effects of their cumulative stress, residents display great agency.

description: We investigate numerical solution of the Dokshitzer-Gribov-Lipatov-Altarelli- Parisi (DGLAP) Q^2 evolution equation for the transversity distribution Delta_T q or the structure function h_1. The leading-order (LO) and next-to- leading-order (NLO) evolution equations are studied. The renormalization scheme is MS or overline{MS} in the NLO case. Dividing the variables x and Q^2 into small steps, we solve the integrodifferential equations by the Euler method in the variable Q^2 and by the Simpson method in the variable x. Numerical results indicate that accuracy is better than 1% in the region 10^{-5}

description: In order to stay within planetary boundaries, it is said that we should change our societies in radical ways. In this paper, we propose and design an alternative future state, acknowledging such a radical change. Embodied as individual climate goals, we take a Speculative Research through Design approach, thereby positioning participants in such a radically different future system.
To shape this speculative system, we engaged experts through interviews and a future vision and backcasting workshop. We translated this vision of a radical change towards a sustainable future, into the concept Spilltime, in which a carbon budget is central. It consists of a CO2e pulse, a CO2e coach, an ambient interface and a CO2e reflection offering detailed information. Utilizing wearable technology, video tracking and a Wizard of Oz approach, we embedded the Spilltime concept in the lives of six participants. Thereby, we were able to provide high resolution real time CO2e feedback in relation to the activities the six participants engaged in.
With this Speculative Research through Design approach, we managed to embody experiences of (radical) future states and enter a deeply reflective space to uncover stories of opportunity and despair around a carbon literacy.

description: We show that scale invariant scattering theory allows to exactly determine the critical points of two-dimensional systems with coupled $O(N)$ and Ising order pameters. The results are obtained for $N$ continuous and include criticality of loop gas type. In particular, for $N=1$ we exhibit three critical lines intersecting at the Berezinskii-Kosterlitz-Thouless transition point of the Gaussian model and related to the $Z_4$ symmetry of the isotropic Ashkin-Teller model. For $N=2$ we classify the critical points that can arise in the XY-Ising model and provide exact answers about the critical exponents of the fully frustrated XY model.

description: Through the design, development and implementation of the Living Room of the Future (LRoTF), we build upon existing work to progress two strands of research. The first explores how media broadcasters may utilise Object-Based Media (OBM) to provide more immersive experiences. Created in conjunction with the BBC R&D the LRofTF utilizes OBM to dynamically customise television content according to audiences’ personal, contextual and derived data. OBM works by breaking media into smaller parts or ‘objects’, describing how they relate to each other semantically, and then reassembling them into personalized programmes. In addition to this media-delivery aspect, the LRoTF explores data protection issues that arise from OBM’s use of databy integrating with the privacy-enhancing Databox system. The second research focus develops understandings of Design Fiction. While the ‘World Building’ approach to Design Fiction describes strategies that place emerging technologies in potential futures, this work expands the scope of these prototypes to create a world within which audiences co-produce a ‘lived’ experience of the future as an ‘Experiential Design Fiction’. By combining the audience’s context with the fiction’s diegesis this research demonstrates a method for extrapolating today’s emerging technologies to create an immersive experience of a possible mundane reality of tomorrow.
An energy window study of light transmission-disorder relationship in 1D photonic structures

description: While the light transmission of photonic crystals is characterized by the photonic band gap, the one of disordered photonic structures is typified by a multiplicity of transmission depths. The total transmission over a range of wavelengths is related to the width of such range, but also to the type of disorder. Less homogeneous disordered structures transmit more light than the ordered counterpart regardless of the wavelengths range width. More homogeneous disordered structures transmit more light than the ordered counterpart only above a certain value of the width. We studied this behaviour with a statistical analysis over 5000 permutations of structures for each wavelength width and for each homogeneity degree (Shannon-Wiener index).

Recursion Relations in $p$-adic Mellin Space

description: In this work, we formulate a set of rules for writing down $p$-adic Mellin amplitudes at tree-level. The rules lead to closed-form expressions for Mellin amplitudes for arbitrary scalar bulk diagrams. The prescription is recursive in nature, with two different physical interpretations: one as a recursion on the number of internal lines in the diagram, and the other as reminiscent of on-shell BCFW recursion for flat-space amplitudes, especially when viewed in auxiliary momentum space. The prescriptions are proven in full generality, and their close connection with Feynman rules for real Mellin amplitudes is explained. We also show that the integrands in the Mellin-Barnes representation of both real and $p$-adic Mellin amplitudes, the so-called pre-amplitudes, can be constructed according to virtually identical rules, and that these pre-amplitudes themselves may be re-expressed as products of particular Mellin amplitudes with complexified conformal dimensions.

description: We present a simple, pedagogical introduction to the statistics of extreme values. Motivated by a string of record high temperatures in December 1998, we consider the distribution, averages and lifetimes for a simplified model of such ``records.'' Our ``data'' are sequences of independent random numbers all of which are generated from the same probability distribution. A remarkable universality emerges: a number of results, including the lifetime histogram, are universal, that is, independent of the underlying distribution.

description: We used numerical simulations based on the finite element method (FEM) to calculate both the amplitude and phase information of the scattered electric field from random rough surfaces, which can be directly compared to ellipsometric measurements and effective medium approximation (EMA) calculations. FEM can serve as an exploration tool for the relationship between the thickness of the surface roughness evaluated by Bruggeman EMA and the morphological parameters of the surface, such as the root mean square height, the lateral auto-correlation length and the typical average slope. These investigations are of high interest in case of poly-crystalline and amorphous materials. The paper focuses on the simulations of rough Si surfaces. The ellipsometric calculations from FEM and EMA simulations match for wavelengths of illumination much shorter than the typical feature size of the surface. Furthermore, for these cases, the correlation between the EMA thickness and the root mean square height of the roughness for a given auto-correlation length is quadratic, rather than linear, which is in good agreement with experimental measurements and analytical calculations presented in recent reports.
