description: The fluidity of concrete is a key parameter that determines the printability of the mixture in an extrusion-based printing process. The printability of concrete is influenced by the relative proportions of aggregate and paste, paste rheology and the aggregate properties. The complex relationship of the aggregate packing and paste content in excess to the demand and the printability of the mixture is explored using concrete made with two different types of aggregate, which have different packing densities. The paste content requirement for printable concrete mixture varies with aggregate packing and gradation. The mixtures made of aggregate with a higher maximum packing density are printable with a lower paste requirement. The printability of concrete is identified with respect to aggregate packing and excess paste content. Concrete mixtures of the same paste rheology are printable at the same excess paste content irrespective of the aggregate packing densities.

description: The formation of coherent structures in noise driven phenomena and in Turbulence is a complex and fundamental question. A particulary important structure is the so-called Rogue Wave (RW) that arises as the sudden appearance of a localized and giant peak. First studied in Oceanography, RWs have been extensively investigated in Optics since 2007, in particular in optical fibers experiments on supercontinua and optical turbulence. However the typical time scales underlying the random dynamics in those experiments prevented --up to now-- the direct observation of isolated RWs. Here we report on the direct observation of RWs, using an ultrafast acquisition system equivalent to microscope in the time domain. The RWs are generated by nonlinear propagation of random waves inside an optical fiber, and recorded with $\sim 250$~fs resolution. Our experiments demonstrate the central role played by "breathers-like" solutions of the one-dimensional nonlinear Schrödinger equation (1D-NLSE) in the formation of RWs

description: Manufactured sand is increasingly used in concrete production. We study the effects of substituting parts of the binder with manufactured filler (particle size 0.04 - 0.250 mm) on the printability of cement paste experimentally and numerically. An experimental program explored water-to-binder ratios of 0.4 and filler-to-binder mass ratios fi/b = 0.15 - 0.85. The study investigated suspension properties and rheology like maximum packing, mini-slump, plastic viscosity, and yield stress. Printability, on a lab scale, was observed by printer flow measurements (“extrudability”) and buildability (shape retention, deformation layer adhesion, deformation, macro voids). Additionally, a computational fluid dynamics model (CFD) is developed to simulate the 3D printing of the filler-modified cement paste and assess its printability. Results show that as maximum packing increases, slump flow (yield stress) decreases as expected. The best shape retention and layer adhesion were found in mixes with maximum packing = 0.94, 0.96, and 0.98. The mix with the highest yield stress showed the best shape retention but had more macro voids in the cross-section and rougher surfaces. To confirm the accuracy of the CFD model, the cross-sectional shapes of the deposited part from simulations are compared with the printed ones. It seems more work is needed to get a good correlation with the same process parameters.

Direct numerical solution of the two-particle Lippmann-Schwinger equation in coordinate space using the multi-variable Nystrom method

Year: 2016

description: Direct numerical solution of the coordinate-space integral-equation version of the two-particle Lippmann Schwinger (LS) equation is considered as a means of avoiding the shortcomings of partial-wave expansion at high energies and in the context of few-body problems. Upon the regularization of the singular kernel of the three-dimensional LS equation by a subtraction technique, a three-variate quadrature rule is used to solve the resulting nonsingular integral equation. To avoid the computational burden of discretizing three variables, advantage is taken of the fact that, for central potentials, azimuthal angle can be integrated out leaving a two-variable reduced integral equation. Although the singularity in the the kernel of the two-variable integral equation is weaker than that of the three-dimensional equation, it nevertheless requires careful handling for quadrature discretization to be applicable. A regularization method for the kernel of the two-variable integral equation is derived from the treatment of the singularity in the three-dimensional equation. A quadrature rule constructed as the direct-product of single-variable quadrature rules for radial distance and polar angle is used to discretize the two-variable integral equation. These two- and three-variable methods are tested on a model nucleon-nucleon potential. The results show that Nystrom method for the coordinate-space LS equation compares favorably in terms of its ease of implementation and effectiveness with the Nystrom method for the momentum-space version of the LS equation .

description: We combine wide and deep galaxy number-count data from GAMA, COSMOS/G10, HST ERS, HST UVUDF and various near-, mid- and far- IR datasets from ESO, Spitzer and Herschel. The combined data range from the far-UV (0.15microns) to far-IR (500microns), and in all cases the contribution to the integrated galaxy light (IGL) of successively fainter galaxies converges. Using a simple spline fit, we derive the IGL and the extrapolated-IGL in all bands. We argue undetected low surface brightness galaxies and intra-cluster/group light is modest, and that our extrapolated-IGL measurements are an accurate representation of the extra-galactic background light. Our data agree with most earlier IGL estimates and with direct measurements in the far-IR, but disagree strongly with direct estimates in the optical. Close agreement between our results and recent very high-energy experiments (H.E.S.S. and MAGIC), suggest that there may be an additional foreground affecting the direct estimates. The most likely culprit could be the adopted Zodiacal light model. Finally we use a modified version of the two-component model to integrate the EBL and obtain measurements of the Cosmic Optical Background (COB) and Cosmic Infrared Background (CIB) of: $24^{+4}_{-4}$nWm$^{-2}$sr$^{-1}$ and $26^{+5}_{-5}$nWm$^{-2}$sr$^{-1}$ respectively (48:52%). Over the next decade, upcoming space missions such as Euclid and WFIRST, have the capacity to reduce the COB error to $<1\%$, at which point comparisons to the very high energy data could have the potential to provide a direct detection and measurement of the reionisation field.

description: Recent years have seen a significant increase in interest in low carbon materials in the construction sector. Low-carbon cements are expected to improve concrete technology sustainability but solutions also include the use of materials that were previously considered industrial waste or by-products, such as clayey earthen materials and, more broadly, any excavated soil containing a proportion of clay. Unlike cementitious materials, the highly viscous nature of clay means that construction methods need to be modified and this has often slowed down the development of these clay products. The rapid development of additive manufacturing methods means that these viscous materials can be optimized: this means adapting not only the formulation of the clay matrix materials, but also the measurement methods. The use of 3D printing and the range of architected materials it offers means that a large number of applications can be envisaged, but the behavior of the materials must be mastered in order to ensure the technical feasibility and stability of such a printed structure. This study focuses on the measurement of rheological properties in relation to the stability of the structure once printed. While for cement-based materials, chemical setting allows a stiffness to be achieved that satisfies structural stability during printing, clay-based materials do not have the same buildability properties. The thixotropic properties of the material need to be advantageously exploited and the way in which it is characterized needs to be adapted. While extrusion behavior can be easily characterized by shear tests, structural stability requires adaptation of rheological tests following an extensional configuration. This article explores the capabilities of dynamic mechanical analysis (DMA) on cement and clay-based materials to determine their visco-elastic properties under compression in order to predict the stability of the structure to be printed. The thixotropic nature of materials with such a clay matrix is the subject of an in-depth study via a three-stage extensional DMA. The decorrelation of the elastic contribution from the viscous contribution and the determination of the critical deformation, bounding the linear viscoelastic range, make it possible to quantify the response of the printed material under compression, and qualitatively compared with pseudo-elastic modulus measurements.

description: This study explores the rheological properties and 3D printability of metakaolin-based geopolymers (GP) designed for fabricating inorganic filters for liquid waste decontamination. Through this study, we investigate the influence of various additives on the rheological properties essential for Direct Ink Writing (DIW) applications. Specifically, we examine the effects of polyethylene glycol (PEG), carbonate minerals, and hexadecyltrimethylammonium bromide (CTAB) on GP formulations to optimize printability and structural integrity. Our findings demonstrate that incorporating PEG as a shear-thinning agent, along with inorganic particles, significantly enhances the printability of the GP pastes. We model the buildability of each formulation by evaluating the evolution of yield stress and the impacts of PEG, CTAB, and carbonate minerals. The optimal formulation, containing 2 wt% PEG and 30 wt% CaCO3, exhibits superior rheological properties, ensuring precise filament extrusion and stable layer stacking. Additionally, a case study validates the printability of selected GP formulations and examines the porosity and topology of the macro- and micro-porous networks within the 3D-printed lattices, which are critical for effective filtration. This research elucidates the structure-processing-properties relationship in 3D-printed GP lattices, offering valuable insights for advancing filtration and decontamination technologies.

description: We exploit a sample of ultra-faint high-redshift galaxies (demagnified HST $H_{160}$ magnitude $>30$) in the Frontier Fields clusters A2744 and M0416 to constrain a theoretical model for the UV luminosity function (LF) in the presence of photoionization feedback. The objects have been selected on the basis of accurate photometric redshifts computed from multi-band photometry including 7 HST bands and deep $K_s$ and IRAC observations. Magnification is computed on an object-by-object basis from all available lensing models of the two clusters. We take into account source detection completeness as a function of luminosity and size, magnification effects and systematics in the lens modeling of the clusters under investigation. We find that our sample of high-$z$ galaxies constrain the cut-off halo circular velocity below which star-formation is suppressed by photo-ionization feedback to $v_c^{\rm cut} < 50$ km s$^{-1}$. This circular velocity corresponds to a halo mass of $\approx5.6\times10^9~M_\odot$ and $\approx2.3\times10^9~M_\odot$ at $z=5$ and 10 respectively: higher mass halos can thus sustain continuous star formation activity without being quenched by external ionizing flux. More stringent constraints are prevented by the uncertainty in the modeling of the cluster lens, as embodied by systematic differences among the lens models available.

In a stringy framework, starting from a warped throat-like Klebanov-Strassler geometry, we show that all the massless higher rank antisymmetric tensor fields are heavily suppressed due to the background fluxes leading to their invisibility in our Universe.

description: Reducing the clinker consumption in concrete is among the most urgent tasks of the construction industry. This is especially important in the 3D concrete printing (3DCP) context, where high binder contents are often required. In this work, we produced Portland-based binders containing ceramic waste (CW) for 3DCP application. For this purpose, Portland cement was replaced with 20 and 40 wt% CW. The fresh performance of the 3DCP mixes was evaluated through the buildability test, rotational rheometry (vane test), and the slug test. In addition, hydration was followed up to 7 days through isothermal calorimetry, besides 3- and 7-day compressive strength tests. The results showed that replacing cement with 20 and 40 wt% CW increased the yield stress of concrete by 4.5 and 9.3 times, respectively; the lower replacement level was beneficial for buildability, increasing the maximum supported layers from 12 to 30, while the higher content impaired pumpability. The compressive strength of 3DCP decreased by 12% at 3 days of hydration for both replacement levels, while the sample containing 20% CW matched the strength of the reference mix at 7 days. This can be justified by the filler effect coupled with the pozzolanic activity of the residue confirmed by calorimetry. Overall, we found replacing 20% cement with CW was a feasible strategy for reducing the binder content in 3DCP mixes while improving buildability.

description: Lemaître-Tolman-Bondi (LTB) solutions have traditionally been confined to systems with no pressure in which the gravity is due to massive dust, but the solutions are little changed in form if, as in cosmology, the pressure is uniform in space at each comoving time. This allows the equations of cosmology to be deduced in a manner that more closely resembles classical mechanics. It also gives some inhomogeneous solutions with growing condensations and black holes. We give criteria by which the sizes of different closed models of the universe can be compared and discuss conditions for self-closure of inhomogeneous cosmologies with a $Λ$-term.

description: Incompressible, homogeneous and isotropic turbulence is studied by solving the Navier-Stokes equations on a reduced set of Fourier modes, belonging to a fractal set of dimension $D$. By tuning the fractal dimension parameter, we study the dynamical effects of Fourier decimation on the vortex stretching mechanism and on the statistics of the velocity and the velocity gradient tensor. In particular, we show that as we move from $D=3$ to $D \sim 2.8$, the statistics gradually turns into a purely Gaussian one. This result suggests that even a mild fractal mode reduction strongly depletes the stretching properties of the non-linear term of the Navier-Stokes equations and suppresses anomalous fluctuations.

description: Various events in the nature, economics and in other areas force us to combine the study of extremes with regression and other methods. A useful tool for reducing the role of nuisance regression, while we are interested in the shape or tails of the basic distribution, is provided by the averaged regression quantile and namely by the average extreme regression quantile. Both are weighted means of regression quantile components, with weights depending on the regressors. Our primary interest is the averaged extreme regression quantile (AERQ), its structure, qualities and its applications, e.g. in investigation of a conditional loss given a value exogenous economic and market variables. AERQ has several interesting equivalent forms: While it is originally defined as an optimal solution of a specific linear programming problem, hence is a weighted mean of responses corresponding to the optimal base of the pertaining linear program, we give another equivalent form as a maximum residual of responses from a specific R-estimator of the slope components of regression parameter. The latter form shows that while AERQ equals to the maximum of some residuals of the responses, it has minimal possible perturbation by the regressors. Notice that these finite-sample results are true even for non-identically distributed model errors, e.g. under heteroscedasticity. Moreover, the representations are formally true even when the errors are dependent - this all provokes a question of the right interpretation and of other possible applications.

Valence Imbalance of Manganese Ions between Surface and Bulk Enhanced by Fermi-Surface Structure in Layered Manganites

description: To investigate valence imbalance phenomena between the surface and bulk in layered manganites, we analyze an eg-orbital degenerate double-exchange model with surfaces for two types of t2g spin structures. We reconfirm that the surface-induced Friedel oscillations occur in the charged structure and that the number of Mn4+ ions on the surface is larger than that in the bulk. This tendency is found to be more significant, when the eg-electron system has Fermi-surface structures with better nesting properties. The behavior of the Friedel oscillations depends on the nesting properties of the Fermi-surface curves along the direction of the oscillations, and not on the dimension of the system itself. We believe that these results will be useful for the development of high-efficiency cathodes in Li-ion batteries and catalysts.

description: 3D concrete printing (3DCP) has introduced a paradigm shift in construction methodologies, necessitating a reevaluation of quality assessment measures that surpass those of traditional concrete processing. The intricacies of the printing process, characterized by variations in material behavior across different time frames and scales, demand a multifaceted approach to quality control. To address these complexities, quality indicators have been recently divided into three families: quality variation, transient material behavior and geometry. In this context, our paper contributes to the geometric conformity category by introducing three distinct zones within the 3DCP process: the shoulder, steady-state, and foot zones. By analyzing these zones, we aim to provide a simple feature-wise inspection method that predicts the deformation of the printed object, considering the interdependent dynamics of material mix parameters and printing process variables. This study provides an analytical framework for predicting these deformation zones, which helps advance quality control in 3DCP.

description: We study the transport properties of an impurity in a sheared granular gas, in the framework of the Boltzmann equation for inelastic Maxwell models. We investigate here the impact of a nonequilibrium phase transition found in such systems, where the tracer species carries a finite fraction of the total kinetic energy (ordered phase). To this end, the diffusion coefficients are first obtained for a granular binary mixture in spatially inhomogeneous states close to the simple shear flow. In this situation, the set of coupled Boltzmann equations are solved by means of a Chapman-Enskog-like expansion around the (local) shear flow distributions for each species, thereby retaining all the hydrodynamic orders in the shear rate $a$. Due to the anisotropy induced by the shear flow, three tensorial quantities $D_{ij}$, $D_{p,ij}$, and $D_{T,ij}$ are required to describe the mass transport process instead of the conventional scalar coefficients. These tensors are given in terms of the solutions of a set of coupled algebraic equations, which can be \emph{exactly} solved as functions of the shear rate $a$, the coefficients of restitution $α_{sr}$ and the parameters of the mixture (masses and composition). Once the forms of $D_{ij}$, $D_{p,ij}$, and $D_{T,ij}$ are obtained for arbitrary mole fraction $x_1=n_1/(n_1+n_2)$ (where $n_r$ is the number density of species $r$), the tracer limit ($x_1\to 0$) is carefully considered for the above three diffusion tensors. Explicit forms for these coefficients are derived showing that their shear rate dependence is significantly affected by the order-disorder transition.

description: The NP-hard Distinct Vectors problem asks to delete as many columns as possible from a matrix such that all rows in the resulting matrix are still pairwise distinct. Our main result is that, for binary matrices, there is a complexity dichotomy for Distinct Vectors based on the maximum (H) and the minimum (h) pairwise Hamming distance between matrix rows: Distinct Vectors can be solved in polynomial time if H <= 2 ceil(h/2) + 1, and is NP-complete otherwise. Moreover, we explore connections of Distinct Vectors to hitting sets, thereby providing several fixed-parameter tractability and intractability results also for general matrices.

description: In this paper we will examine the consequence of a canonical theory of quantum dust collapse in 2+1 dimensions. The solution of the WDW equation describing the collapse indicates that collapsing shells outside the apparent horizon are accompanied by outgoing shells within the apparent horizon during their collapse phase and stop collapsing once they reach the apparent horizon. Taking this picture of quantum collapse seriously, we determine a static solution with energy density corresponding to a dust ball whose collapse has terminated at the apparent horizon. We show that the boundary radius of the ball is larger than the BTZ radius confirming that no event horizon is formed. The ball is sustained by radial pressure which we determine and which we attribute to the Unruh radiation within it.

description: Precise control of fresh concrete properties is crucial for effective extrusion-based 3D printing. In particular, the evolution of yield stress over time is of interest as it determines the structural build-up of concrete and thus its ability to support subsequent layers during printing. Penetration tests are a standard method to analyze the yield stress and its evolution. However, the duration required to reach a steady state flow around the measurement tip, which is essential to evaluate yield stresses, is rather long. Our research focuses on a novel test setup to reach an accelerated steady state flow during probe penetration. A coupled fast-to-slow penetration approach was developed, leading to the rapid establishment of steady state flow. Experiments were performed using a clay mortar with a consistency comparable to that of cementitious mortars, as typically used in 3D printing. The clay mortar was observed to exhibit an almost constant consistency over time, allowing for experiments that exclude the effect of changing material. The observed variations in forces required for fast and slow penetration tests indicate different underlying friction mechanisms. The force in fast penetration likely overcomes the sliding friction associated with dynamic yield stress, while slow penetration is linked to static friction and static yield stress. This distinction and the establishment of steady state flow is important for understanding material behavior and penetration test dynamics under different stress conditions, in particular for materials for 3D printing applications.

description: In this paper, we present the measurements of the [NII] 205micron line ([NII]205) for a flux-limited sample of 122 (ultra-)luminous infrared galaxies [(U)LIRGs] and 20 additional normal galaxies, obtained with the Herschel Space Observatory. We explore the far-infrared (FIR) color dependence of the [NII]205 (L[NII]205) to the total infrared (LIR) luminosity ratio, and find that L[NII]205/LIR only depends modestly on the 70-to-160 micron flux density ratio (f70/f160) when f70/f160 0.6. We also investigate the relation between L[NII]205 and star formation rate (SFR), and show that L[NII]205 has a nearly linear correlation with SFR, albeit the intercept of such relation varies somewhat with f60/f100, consistent with our previous conclusion that \NIIab\ emission can serve as a SFR indicator with an accuracy of ~0.4 dex, or ~0.2 dex if f60/f100 is known independently. Furthermore, together with the ISO measurements of [NII] 122 micron emission we use a total of ~200 galaxies to derive the local [NII]205 luminosity function (LF) by tying it to the known IR LF with a bivariate method. As a practical application, we also compute the local SFR volume density ($\dotρ_{\rm SFR}$) using the newly derived SFR calibrator and LF. The resulting $\log\,\dotρ_{\rm SFR} = -1.96\pm0.11$ $M_\odot$\,yr$^{-1}$\,Mpc$^{-3}$ agrees well with previous studies. Finally, we determine the electron densities ($n_e$) of the ionized medium for a subsample of 12 (U)LIRGs with both [NII]205 and [NII]122 data, and find that $n_e$ is in the range of ~1-100 cm$^{-3}$, with a median value of 22 cm$^{-3}$

description: Part of a collection of 21 letters sent by William Powell Frith to his great nephew Henry Keyworth Raine, dating from March 16, 1890 to March 29, 1908. William Powell Frith (1819-1909), painter of historical and genre works, including large canvases such as Derby Day (1858). “The Race for Wealth” comprises five paintings, all based around a fictional central character, a corrupt financier called The Spider, and all dealing with the theme of reckless financial speculation. Inspired by characters found in the novels of Charles Dickens and Anthony Trollope, The Spider persuades his victims to invest in dubious schemes. Often compared with Hogarth’s “The Rake’s Progress,” “The Race for Wealth” portrays The Spider’s initial success, his unmasking, his trial, and ends with his imprisonment.

description: Common products designed for the extrusion-based 3DCP method are often unappealing from both economic and environmental perspectives. This is due to their typically high cost as pre-mixed systems (1k-system), intricate formulations, and high cement content. To address this challenge and facilitate the utilization of locally sourced materials in 3DCP, we offer a solution based on admixtures (2k-system). The transition to 2k systems represents a paradigm shift, enabling better control over the individual steps involved in the printing process and increasing room for making the best use of the cement content. The proposed solution includes a retarder admixture to control fresh mortar/concrete rheological properties and a liquid accelerator injected into the extruding nozzle for structural formation regulation and early strength development. An essential aspect of this technology is its ability to enable the utilization of OPC-based and/or blended cement formulations, leading to a substantial reduction in raw material costs promoting cost-effectiveness. Additionally, it emphasizes the integration of locally available materials in 3DCP formulations, contributing to the sustainability of the construction process. Consequently, the technology offers a comprehensive solution to address existing technical and economic challenges hindering widespread 3DCP adoption. In this contribution, OPC cement was selected for its proximity to industrial printing trials, with sustainability in mind during dry mortar mix design. Cement content was reduced to 17% of the total dry mix weight by substituting it with a blend of three lime-stone powders, varying in particle size to optimize packing density. Printing trials at XtreeE facility confirmed the feasibility of the proposed solution in controlling workability, setting time, and strength development.

description: 3D concrete printing is an additive manufacturing process in which elongated beads are assembled in layers to form 3D parts. In cementitious materials, water evaporation as well as the setting of the material results in a volumetric shrinkage of the printed structures. This imposed shrinkage strain, commonly referred to as eigenstrain, is the source of residual progressive stress evolution within the printed parts. Consequently, the accumulation of stress during fabrication and drying may induce cracks, buckling, and surface defects in the final product. Evaluating and modeling the effect of shrinkage on the printed beads is therefore essential to optimize the machine path and process parameters in order to mitigate such issues and guarantee the integrity of the printed parts. In particular, this paper focuses on the development of a compensation strategy such that the final geometry correctly approximates the target geometry. The proposed approach relies on the experimental characterization of the displacement field and hence the total strain by using Digital Image Correlation performed on in-situ imaging of the process. The history of the eigenstrain strain (i.e., shrinkage) has been measured on flat rectangular thin-walled walls, and then used in a mechanical model as an imposed strain. Resulting geometrical distortions have been validated against experiments. On this basis, a simple compensation strategy is proposed consisting in correcting the initial machine path by the opposite of the computed distortions when the structure is subjected to shrinkage. Several examples on various part geometries are presented and discussed. A fast one-dimensional mechanical model named QuadWire proposed recently is being used for numerical simulations, as the final objective is to create large database to train neural network algorithms in order to apply this compensation strategy in real-time during the printing process.
