description: Using a combination of neutron scattering, calorimetry, Quantum Monte Carlo (QMC) simulations and analytic results we uncover confinement effects in depleted, partially magnetized quantum spin ladders. We show that introducing non-magnetic impurities into magnetized spin ladders leads to the emergence of a new characteristic length L in the otherwise scale-free Tomonaga-Luttinger liquid (serving as the effective low-energy model). This results in universal LT scaling of staggered susceptibilities. Comparison of simulation results with experimental phase diagrams of prototypical spin ladder compounds DIMPY and BPCB yields excellent agreement.

Blast waves in two and three dimensions: Euler versus Navier Stokes equations

description: The exact solution of the Euler equation, which describes the time evolution of a blast wave created by an intense explosion, is a classic problem in gas dynamics. However, it has been found that the analytical results do not match with results from molecular dynamics simulation of hard spheres in two and three dimensions. In this paper, we show that the mismatch between theory and simulations can be resolved by considering the Navier Stokes equation. From the direct numerical simulation of the Navier Stokes equation in two and three dimensions, we show that the inclusion of heat conduction and viscosity terms is essential to capture the results from molecular dynamics simulations.

description: We explore the dynamics of $N$ coupled atoms to a generic bosonic reservoir under specific system symmetries. In the regime of multiple atoms coupled to a single reservoir with identical couplings, we identify remarkable effects, notably that the initial configuration of the atomic excited state amplitudes strongly impacts the dynamics of the system and can even fully sever the system from its environment. Additionally, we find that steady state amplitudes of the excited states become independent of the choice of the reservoir. The framework introduced is applied to a structured photonic reservoir associated with a photonic crystal, where we show it reproduces previous theoretical and experimental results and it predicts superradiant behaviour within the single-excitation regime.

description: We introduce two properties, macroscopic mixing and transitive mixing, to represent the macroscopic stability of time evolution of Gibbs measures. We claim that these are fundamental properties of macroscopic systems that exhibit relaxation to an equilibrium state. As an illustration, we show that a simple mechanical system on a lattice possesses these two properties.

description: A new generation of neutrino experiments is testing the $4.8σ$ anomalous excess of electron-like events observed in MiniBooNE. This is of huge importance for particle physics, astrophysics, and cosmology, not only because of the potential discovery of physics beyond the Standard Model, but also because the lessons we will learn about neutrino-nucleus interactions will be crucial for the worldwide neutrino program. MicroBooNE has recently released results that appear to disfavor several explanations of the MiniBooNE anomaly. Here, we show quantitatively that MicroBooNE results, while a promising start, unquestionably do not probe the full parameter space of sterile neutrino models hinted at by MiniBooNE and other data, nor do they probe the $ν_e$ interpretation of the MiniBooNE excess in a model-independent way. Our analysis code is fully available in https://github.com/Harvard-Neutrino/MicroBooNE-analysis-2021.

description: We introduce the {\em Phoenix Simulations}, a suite of highly resolved cosmological simulations featuring hydrodynamics, primordial gas chemistry, Population III and II star formation and feedback, UV radiative transfer, and saved outputs with $Δt$=200 kyr. The suite samples 73,523 distinct primordial star formation events within \npiii distinct regions, forming \ngii second-generation enriched star clusters by $z \geq 12$ within a cumulative 156.25 Mpc$^3$ volume. The regions that lead to enriched star formation contain up to $167$ primordial stars, with 78.7 \% of regions having experienced multiple types of primordial supernovae. The extent of a primordial region, measured by its metal-rich surrounding cloud, is highly variable: the average region has radius $\sim 3$ kpc, with 95 \% confidence limit on the distribution of measured radii is $\sim 5-7$ kpc. For continuing star formation, we find that the metallicity distribution of second generation stars is similar to that of subsequent Population II star formation, with both distributions spanning hyper metal-deficient ([Z/H]$\sim-7$) to super-solar ([Z/H]$\sim0.8$). We find that the metallicity of second generation stars has no strong dependence on the configuration of progenitor supernovae, with the mean metallicity of second-generation stars having $-1.73 < $[Z/H]$<-2.15$. Finally, we create an interpretable regression model to predict the radius of metal-rich influence of \piii star systems within the first 7-18 Myr after the first light. The model predicts the radius with $R_2 \gtrsim 0.4$ and mean squared error $\leq 0.06$. The probability distribution function of predicted radii compares well to that of observed radii with Jensen-Shannon distance $\lesssim 0.2$ for all modelled times.

description: To understand how the multitude of planetary systems that have been discovered come to be, we need to study systems at different evolutionary stages, with different central stars but also in different environments. The most challenging environment for planet formation may be the harsh UV radiation field of nearby massive stars which quickly erodes disks by external photo-evaporation. We have observed the AT Pyx system, located in the head of a cometary globule in the Gum Nebula, to search for signs of ongoing planet formation. We used the extreme adaptive optics imager VLT/SPHERE to observe AT Pyx in polarized light as well as total intensity in the J, H and K-band. Additionally we employed VLT/NACO to observe the system in the L-band. We resolve the disk around AT Pyx in scattered light across multiple wavelengths. We find an extended (>126 au) disk, with an intermediate inclination between 35 deg and 42 deg. The disk shows complex sub-structure and we identify 2 and possibly 3 spiral-like features. Depending on the precise geometry of the disk (which we can not unambiguously infer from our data) the disk may be eccentric with an eccentricity of ~0.16 or partially self-shadowed. The spiral features and possible eccentricity are both consistent with signatures of an embedded gas giant planet equal in mass to Jupiter. Our own observations can rule out brown dwarf companions embedded in the resolved disk, but are not sensitive enough to detect gas giants. AT Pyx is the first disk in a cometray globule in the Gum Nebula which is spatially resolved. By comparison with disks in the Orion Nebula Cluster we note that the extension of the disk may be exceptional for this environment if the external UV radiation field is comparable to other cometary globules in the region. The signposts of ongoing planet formation are intriguing and need to be followed up with higher sensitivity.

description: Construction of buildings is an inevitable part of an expanding city or for the developing infrastructure of a country. As a result of the high rate of construction works that are happening around the world, harmful carbon emission continues to riseand cause a serious threat to our ecosystem. Therefore, we must consider the materials that are used in the construction process that causes carbon emission and replace them with materials that are more eco-friendly.In this paper, we take into consideration two conventional materials that are used in construction, Ordinary Portland cement and fiberglass insulation. And replace themwith their green and sustainable alternatives Ferrock and Hempcrete.Ferrock is an iron-based binding compound that is used to bind different waste materials for carbon-negative building materials. Iron dust is a waste from the Ironindustry that normally is discarded used along with small quantities of limestone,recycled glass (source of silica) and Oxalic acid.Hempcrete is a bio-composite material that consists of hemp hurds (shives), lime and sand. The lime-based binder under goes a carbonation process in which CO2 is absorbed.Every phase in Ferrock and Hempcrete production will be assessed and studied andwill be compared with that of Ordinary Portland Cement (OPC) and Fiberglass. Both these alternatives will be compared with their conventional predecessors based ontheir carbon dioxide emission, compressive test, Thermal conductivity, cost, andapplications.
title: Producing space investigating spatial design practices in a market moment

Publisher: name: London School of Economics and Political Science (LSE)
Year: 2017
Subjects: subject: H Social Sciences
subject: HM Sociology

description: This thesis is an investigation of commercial spatial design practices. It contributes to an emerging sociological and anthropological scholarship on design and is grounded in a studio ethnography of a large London-based architecture and spatial design practice. The analysis is based on an understanding of spatial design as conceptual, problem-solving and form-giving and focusses on the mediating role designers take on. It is framed by a pragmatist approach that highlights the significance of mediation, contextuality and agency in design as situated practice. The purpose of this project is to analyse the complicated set-up of spatial design as creative, material and commercial practice against the backdrop of distinct competitive and regulatory environments. Here, the “market moment” provides the empirical window for investigating how spatial design is premised on linking up creativity, space and commerce. The thesis suggests that studio studies are crucial for retrieving a humanist element in sociological interpretations of (spatial) design to help analyse the significance of materiality and commerciality within design as creative-conceptual work. In the context of an emerging and increasingly politicised design scholarship, this can provide avenues for examining the nuanced forms of design agency as well as design’s entanglement with existing and emerging socio-economic conditions.

Year: 2017
Subjects: subject: H Social Sciences

description: This research is an ethnography about the curation of the street food scene in London that looks at processes of cultural calculation to make markets and to assemble marketplaces. The main research question that is guiding this thesis is how is the street food scene in London being curated? This inquiry follows previous research in cultural economies in different scenes of cultural production like advertising, fashion or music (Du Gay and Pryke, 2002; Slater, 2002a; Entwistle, 2006, 2009; McFall, 2002, 2009, 2013; Ariztía, 2015; Negus, 2002; Law, 2002; McRobbie, 2016; Arriagada, 2014; Arriagada and Cruz, 2014). I am focussing on the idea of curation as analytical vehicle to understand the work of cultural intermediaries (Bourdieu, 1984) as a process of value generation, in which they culturally calculate markets (Callon, 1998; Callon, Méadel and Rabeharisoa, 2002; Slater 2002a) and assemble marketplaces (Farías, 2010; McFarlane, 2011a, 2011b, 2011c) by putting together knowledge, people, objects, aesthetics and other materials that configure the scene. This ethnography focusses on the working practices of market organisers, particularly from a company that I will call EAT-LONDON and four food traders who work in these and other markets. Nine months of fieldwork were conducted, working at offices, markets and food stalls across London. Through this empirical work with actors in the street food scene, rich data was obtained with the purpose of analysing how markets are formed in cultural economies, and how markets create place. Curators are actors that shape the social using their embodied and social knowledge to separate businesses, audiences or places based on the distinction of this cultural scene (Johnston and Baumann, 2015; Naccarato and Lebesco, 2012; Cronin et. al., 2014). The practice of curation reveals how economic calculations are also configured by cultural distinctions and how place is assembled and emerging from multiple actors’ relationships and negotiations of value.

description: The utility of collocating robots largely depends on the easy and intuitive interaction mechanism with the human. If a robot accepts task instruction in natural language, first, it has to understand the user's intention by decoding the instruction. However, while executing the task, the robot may face unforeseeable circumstances due to the variations in the observed scene and therefore requires further user intervention. In this article, we present a system called Talk-to-Resolve (TTR) that enables a robot to initiate a coherent dialogue exchange with the instructor by observing the scene visually to resolve the impasse. Through dialogue, it either finds a cue to move forward in the original plan, an acceptable alternative to the original plan, or affirmation to abort the task altogether. To realize the possible stalemate, we utilize the dense captions of the observed scene and the given instruction jointly to compute the robot's next action. We evaluate our system based on a data set of initial instruction and situational scene pairs. Our system can identify the stalemate and resolve them with appropriate dialogue exchange with 82% accuracy. Additionally, a user study reveals that the questions from our systems are more natural (4.02 on average on a scale of 1 to 5) as compared to a state-of-the-art (3.08 on average).

description: Polystyrene foams have become more and more important owing to their lightweight potential and their insulation properties. Progress in this field is expected to be realized by foams featuring a microcellular morphology. However, large-scale processing of low-density foams with a closed-cell structure and volume expansion ratio of larger than 10, exhibiting a homogenous morphology with a mean cell size of approximately 10 mu m, remains challenging. Here, we report on a series of 4,4 `-diphenylmethane substituted bisamides, which we refer to as kinked bisamides, acting as efficient supramolecular foam cell nucleating agents for polystyrene. Self-assembly experiments from solution showed that these bisamides form supramolecular fibrillary or ribbon-like nanoobjects. These kinked bisamides can be dissolved at elevated temperatures in a large concentration range, forming dispersed nano-objects upon cooling. Batch foaming experiments using 1.0 wt.% of a selected kinked bisamide revealed that the mean cell size can be as low as 3.5 mu m. To demonstrate the applicability of kinked bisamides in a high-throughput continuous foam process, we performed foam extrusion. Using 0.5 wt.% of a kinked bisamide yielded polymer foams with a foam density of 71 kg/m(3) and a homogeneous microcellular morphology with cell sizes of approximate to 10 mu m, which is two orders of magnitude lower compared to the neat polystyrene reference foam with a comparable foam density.

This solves the Creutzig and Gaiotto conjectures in the case of type ABC. If the twist is trivial, the resulting algebras correspond to chiral differential operators in the chiral case, and to WZW models in the non-chiral case.

description: Cosmological and astrophysical surveys in various wavebands, in particular from the radio to the far-infrared, offer a unique view of the universe's properties and the formation and evolution of its structures. After a preamble on the so-called tension problem, which occurs when different types of data are used to determine cosmological parameters, we discuss the role of fast radio bursts in cosmology, in particular for the missing baryon problem, and the perspectives from the analysis of the 21 cm redshifted line from neutral hydrogen. We then describe the Planck Legacy Archive, its wealth of scientific information and next developments, and the promising perspectives expected from higher resolution observations, in particular for the analysis of the thermal Sunyaev-Zel'dovich effect. Three cosmological results of the Planck mission are presented next: the implications of the map of Comptonization fluctuations, the dipole analysis from cross-correlating cosmic microwave background anisotropy and Comptonization fluctuation maps, and the constraints on the primordial tensor-to-scalar perturbation ratio. Finally, we discuss some future perspectives and alternative scenarios in cosmology, such as the study of the Lorentz invariance violation with the cosmic microwave background polarization, the introduction of new gravitational degrees of freedom to solve the dark matter problem, and the exploitation of the magnification bias with high-redshift sub-millimeter galaxies to constrain cosmological parameters.

description: Synchronization of turbulence in channel flow is investigated using continuous data assimilation. The flow is unknown within a region of the channel. Beyond this region the velocity field is provided, and is directly prescribed in the simulation, while the pressure is unknown throughout the entire domain. Synchronization takes place when the simulation recovers the full true state of the flow, or in other words when the missing region is accurately re-established, spontaneously. Successful synchronization depends on the orientation, location and size of the missing layer. For friction Reynolds numbers up to one thousand, wall-attached horizontal layers can synchronize as long as their thickness is less than approximately thirty wall units. When the horizontal layer is detached from the wall, the critical thickness increases with height and is proportional to the local wall-normal Taylor microscale. A flow-parallel, vertical layer that spans the height of the channel synchronizes when its spanwise width is on the order of the near-wall Taylor microscale, while the criterion for a crossflow vertical layer is set by the advection distance within a Lyapunov timescale. Finally, we demonstrate that synchronization is possible when only planar velocity data are available, rather than the full outer state, as long as the unknown region satisfies the condition for synchronization in one direction. These numerical experiments demonstrate the capacity of accurately reconstructing, or synchronizing, the missing scales of turbulence from observations, using continuous data assimilation.

description: Stabilized dense emulsions display a rich phenomenology connecting microstructure and rheology. In this work we study how an emulsion with a finite yield stress can be built via large-scale stirring. By gradually increasing the volume fraction of the dispersed minority phase, under the constant action of a stirring force, we are able to achieve volume fractions close to $80\%$. Despite the fact that our system is highly concentrated and not yet turbulent we observe a droplet size distribution consistent with the $-10/3$ scaling, often associated to inertial range droplets breakup. We report that the polydispersity of droplet sizes correlates with the dynamics of the emulsion formation process. Additionally we quantify the visco-elastic properties of the dense emulsion finally obtained and we demonstrate the presence of a finite yield stress. The approach reported can pave the way to a quantitative understanding of the complex interplay between the dynamics of mesoscale constituents and the large scale flow properties yield-stress fluids.

description: In this work we proof that the one-body position operator for periodic systems that we have recently proposed [Phys. Rev. B 99, 205144] is unique modulo a phase factor and an additive constant. The proof uses several general physical constraints that a periodic one-body position operator should satisfy. We show that these constraints are sufficient to uniquely define a position operator that is compatible with periodic boundary conditions.

description: Noticing that the space of the solutions of a first order Hamiltonian field theory has a pre-symplectic structure, we describe a class of conserved charges on it associated to the momentum map determined by any symmetry group of transformations. Gauge theories are dealt with by using a symplectic regularization based on an application of Gotay's coisotropic embedding theorem. The analysis of Electrodynamics and of the Klein-Gordon theory illustrates the main results of the theory as well as the emergence of the energy-momentum tensor algebra of conserved currents.

description: Abstract

Dopamine plays a crucial role as a neuroregulatory molecule and is secreted during exercise, although its full range of physiological functions is not yet fully understood. Recent research has uncovered a previously unknown role for dopamine in suppressing inflammation, which is particularly relevant in conditions like colon cancer, where prolonged inflammation can play a significant role in the development and progression of the disease. In this study, the anti-inflammatory effects of dopamine were investigated using a colon cancer model with McCOY cells. These cells were cultured using DMEM, and their IC50 (the concentration at which 50% growth inhibition occurs) was determined through MTT assay. The study assessed the expression levels of key markers, including BCl-2, TNF-α, NF-κB, and IL-6, at concentrations of 50 and 100 µg/ml, both below the IC50 value. To gain insights into the molecular interactions, Schrodinger software was employed for docking analysis, focusing on the interaction between NF-κB (PDB: 5T8O) and dopamine (CID 681). The results of this investigation demonstrated that dopamine exhibited significant growth inhibition in McCOY cells, with an IC50 value of 266.32±3.1 µg/ml. Furthermore, dopamine downregulated the expression of BCl-2, NF-κB, and IL-6, while paradoxically increasing the expression of TNF-α. Through docking analysis, it was revealed that dopamine formed bonds with NF-κB through two hydrogen bonds, specifically with ASP53 and ALA54. In summary, this study sheds light on the promising anti-cancer potential of dopamine by blocking the NF-κB signaling pathway in McCOY cells.
Localization persisting under aperiodic driving

description: Localization may survive in periodically driven (Floquet) quantum systems, but is generally unstable for aperiodic drives. In this work, we identify a hidden conservation law originating from a chiral symmetry in a disordered spin-1/2 XX chain. This protects indefinitely long-lived localization for general--even aperiodic--drives. Therefore, rather counter-intuitively, adding further potential disorder which spoils the conservation law delocalizes the system, via a controllable parametrically long-lived prethermal regime. This provides a first example of persistent single-particle `localization without eigenstates'.

description: We present a novel clustering algorithm, visClust, that is based on lower dimensional data representations and visual interpretation. Thereto, we design a transformation that allows the data to be represented by a binary integer array enabling the use of image processing methods to select a partition. Qualitative and quantitative analyses measured in accuracy and an adjusted Rand-Index show that the algorithm performs well while requiring low runtime and RAM. We compare the results to 6 state-of-the-art algorithms with available code, confirming the quality of visClust by superior performance in most experiments. Moreover, the algorithm asks for just one obligatory input parameter while allowing optimization via optional parameters. The code is made available on GitHub and straightforward to use.
