Structural metamaterials with Saint-Venant edge effect reversal
Creators: name: Karpov, Eduard

Subjects: subject: Mechanical Engineering

description: When a usual material is loaded statically at surfaces, fine fluctuations of surface strain diminish fast in the material volume with the distance to the surface, a phenomenon widely known as the Saint-Venant edge effect. In this paper, highly nonlocal discrete lattices are explored to demonstrate structural metamaterials featuring reversal of the Saint-Venant edge effect. In these materials, certain coarse patterns of surface strain may decay faster than the finer ones. This phenomenon is shown to arise from anomalous behavior of the Fourier modes of static deformation in the material, and creates opportunities for blockage, qualitative modification and in-situ recognition of surface load patterns. Potential applications and useful practical techniques of spectral analysis of deformation, density of states and phase diagram mapping are outlined.

description: We give the correct analytic expression of a finite integral appearing in the four-loop computation of the renormalization-group functions for the two-dimensional nonlinear sigma-model on the square lattice with standard action, explaining the origin of a numerical discrepancy. We revise the numerical expressions of Caracciolo and Pelissetto for the perturbative corrections of the susceptibility and of the correlation length. For the values used in Monte Carlo simulations, N=3, 4, 8, the second perturbative correction coefficient of the correlation length varies by 3%, 4%, 3% respectively. Other quantities vary similarly.

description: We present a Halo Occupation Distribution (HOD) analysis of the luminosity- and colour-dependent galaxy clustering in the Sloan Digital Sky Survey. A novelty of our technique is that it uses a combination of clustering measurements in luminosity bins to perform a global likelihood analysis, simultaneously constraining the HOD parameters for a range of luminosity thresholds. We present simple, smooth fitting functions which accurately describe the resulting luminosity dependence of the best-fit HOD parameters. To minimise systematic halo modelling effects, we use theoretical halo 2-point correlation functions directly measured and tabulated from a suite of $N$-body simulations spanning a large enough dynamic range in halo mass and spatial separation. Thus, our modelling correctly accounts for non-linear and scale-dependent halo bias as well as any departure of halo profiles from universality, and we additionally account for halo exclusion using the hard sphere approximation. Using colour-dependent clustering information, we constrain the satellite galaxy red fraction in a model-independent manner which does not rely on any group-finding algorithm. We find that the resulting luminosity dependence of the satellite red fraction is significantly shallower than corresponding measurements from galaxy group catalogues, and we provide a simple fitting function to describe this dependence. Our fitting functions are readily usable in generating low-redshift mock galaxy catalogues, and we discuss some potentially interesting applications as well as possible extensions of our technique.

description: We show that axion domain walls gain spontaneous magnetization in early universe by trapping either electrons or positrons with their spins polarized. The reason is that the walls produces an attractive potential for these particles. We argue that the wall bounded by an axionic superconducting string leaves a magnetic field after its decay. We obtain a field $\sim 10^{-23}$ Gauss on the scale of horizon at the recombination.

description: This study applied the Bayesian approach to estimate people’s willingness to pay (WTP) for mitigation of environmental hazards in oil producing areas in Nigeria. The Bayesian approach enabled estimation of the mixed logit model employing the normal and log-normal distributions of WTP parameters. The model estimate indicating a negative WTP values for the status quo (STAQUO) attribute suggests that people in oil producing areas in Nigeria do not like the current welfare situation and environmental condition which are characterised by environmental problems, affecting adequate use of resources and ecosystem services. The results also show a comparatively higher WTP for food safety (FOODSAF), poverty rate (POVERTY) and unemployment rate (UNEMP) respectively, suggesting people’s desire for mitigation of undesirable livelihood (welfare) impacts of resource exploitation. On the other hand, the results also indicate positive WTP coefficients for land and water pollution from oil spills (SPILL), gas flaring (GFLARE) and land occupied by oil and gas pipelines (LOCC), suggesting that majority of the people are in support of mitigation strategies or policy change that would ensure significant reduction in environmental pollution, gas flaring, and land-take by oil and gas companies. Oil and gas companies are encouraged to ensure mitigation of environmental and livelihood impacts of the crude oil and gas extraction, including reduction in gas flaring, based on environmental laws and global best drilling practices. The study further recommends application of the willingness to pay approach as an important strategy for assessing the values of environmental resources and the impact of resource use.
Deep Listening: Early Computational Composition and its Influence on Algorithmic Aesthetics
Creators: name: Funk, Tiffany
Publisher: name: University of Illinois at Chicago
Year: 2021
Subjects: Uncategorized

description: The popularity of the program DeepDream, created by Google engineer Alexander Mordvintsev, exploded due to the open source availability of its uncanny, hallucinogenic aesthetic. Once used to synthesize visual textures, the program popularized the concept of neural network training through image classification algorithms, inspiring visual art interrogating machine learning and the training of proprietary prediction algorithms; though DeepDream has facilitated the production of many mundane examples of surreal computer art, it has also helped to produce some conceptually rich visual investigations, including MacArthur “genius” awardee Trevor Paglen’s recent installation A Study of Invisible Images. While the significance of trained neural networks is presently considered valuable to computer vision experimentation, a medial archaeological investigation of the conceptual underpinnings of machine learning reveals the fundamental influence early sonic experiments in computational music have in its computational and conceptual framework. Early computational music works, such as Lejaren Hiller Jr. and Leonard Isaacson’s Illiac Suite (1957), the first score composed by a computer, as well as Hiller and John Cage’s ambitious multimedia performance HPSCHD (1969), used stochastic models to automate game-like processes, such as Giovanni Pierluigi da Palestrina’s Renaissance-era polyphonic instruction, as well as the I Ching divination process of casting coins or yarrow stalks. Hiller's concerns regarding the historical use of compositional/mathematical gameplay uncovers a conceptual and performative emphasis anticipating the “training” of visual models. Through the adverse reactions of audiences to Hiller’s compositions, written by what the press deemed derogatorily “An electronic brain” in 1957 parallel public reactions to the disturbing mutations of DeepDream, popular participation in the open source project signals a growing willingness to collaborate creatively with computers to interrogate both computational and cognitive processes.

description: The photoproduction reaction gamma p -> mu+ mu- p has been studied in ep interactions using the ZEUS detector at HERA. The data sample corresponds to an integrated luminosity of 43.2 pb^{-1}. The Upsilon meson has been observed in photoproduction for the first time. The sum of the products of the elastic Upsilon(1S), Upsilon(2S), Upsilon(3S) photoproduction cross sections with their respective branching ratios is determined to be 13.3 +- 6.0(stat.)^{+2.7}_{-2.3}(syst.) pb at a mean photon-proton centre of mass energy of 120 GeV. The cross section is above the prediction of a perturbative QCD model.

description: While G-protein coupled receptors (GPCRs) constitute the largest class of membrane proteins, structures and endogenous ligands of a large portion of GPCRs remain unknown. Due to the involvement of GPCRs in various signaling pathways and physiological roles, the identification of endogenous ligands as well as designing novel drugs is of high interest to the research and medical communities. Along with highlighting the recent advances in structure-based ligand discovery, including docking and molecular dynamics, this article focuses on the latest advances for automating the discovery of bioactive ligands using machine learning. Machine learning is centered around the development and applications of algorithms that can learn from data automatically. Such an approach offers immense opportunities for bioactivity prediction as well as quantitative structure-activity relationship studies. This review describes the most recent and successful applications of machine learning for bioactive ligand discovery, concluding with an outlook on deep learning methods that are capable of automatically extracting salient information from structural data as a promising future direction for rapid and efficient bioactive ligand discovery.

description: In quantum chromodynamics (QCD) at nonzero chemical potential, the eigenvalues of the Dirac operator are scattered in the complex plane. Can the fluctuation properties of the Dirac spectrum be described by universal predictions of non-Hermitian random matrix theory? We introduce an unfolding procedure for complex eigenvalues and apply it to data from lattice QCD at finite chemical potential $μ$ to construct the nearest-neighbor spacing distribution of adjacent eigenvalues in the complex plane. For intermediate values of $μ$, we find agreement with predictions of the Ginibre ensemble of random matrix theory, both in the confinement and in the deconfinement phase.

description: Experimentally, Raman continuum for $A_g$ and $B_g$ geometry exhibits peaks far apart from each other (about 80 to 150 $\rm cm^{-1}$) in frequency. The former is insensitive to doping over a small range where $T_c$ does not vary much whereas the latter shifts towards higher frequencies. We calculate the electronic Raman scattering intensities using the `modified spin bag model'. We show that the calculated results have natural explanation to the observed anamolous peak separation and peculiar doping dependence.

description: We present a Euclidean quantum gravity model in which random graphs dynamically self-assemble into discrete manifold structures. Concretely, we consider a statistical model driven by a discretisation of the Euclidean Einstein-Hilbert action; contrary to previous approaches based on simplicial complexes and Regge calculus our discretisation is based on the Ollivier curvature, a coarse analogue of the manifold Ricci curvature defined for generic graphs. The Ollivier curvature is generally difficult to evaluate due to its definition in terms of optimal transport theory, but we present a new exact expression for the Ollivier curvature in a wide class of relevant graphs purely in terms of the numbers of short cycles at an edge. This result should be of independent intrinsic interest to network theorists. Action minimising configurations prove to be cubic complexes up to defects; there are indications that such defects are dynamically suppressed in the macroscopic limit. Closer examination of a defect free model shows that certain classical configurations have a geometric interpretation and discretely approximate vacuum solutions to the Euclidean Einstein-Hilbert action. Working in a configuration space where the geometric configurations are stable vacua of the theory, we obtain direct numerical evidence for the existence of a continuous phase transition; this makes the model a UV completion of Euclidean Einstein gravity. Notably, this phase transition implies an area-law for the entropy of emerging geometric space. Certain vacua of the theory can be interpreted as baby universes; we find that these configurations appear as stable vacua in a mean field approximation of our model, but are excluded dynamically whenever the action is exact indicating the dynamical stability of geometric space. The model is intended as a setting for subsequent studies of emergent time mechanisms.

description: Objective: The number of primary care providers has not kept pace with the increasing number of underserved rural populations placing unprecedented demands on the healthcare system and the gap is expected to widen with shortages projected to increase across the United States. Given the urgent need to grow and expand the number of trained diverse primary care providers in rural communities, an innovative sustainable program was implemented to recruit and train diverse rural advanced practice nurses. Building on the successful rural medical and rural pharmacy educational programs at the UIC Health Sciences Campus in Rockford, a rural nursing program with interprofessional curriculum was designed and refined to enable nursing students along with two other professions to develop appreciation, insight, and knowledge of rural healthcare and health disparities in a variety of rural settings as part of an interprofessional team.Methods: A mixed-methods program evaluation approach utilized both quantitative and qualitative data to evaluate program satisfaction and inform ongoing program refinement.Results: Students indicated positive responses to this interprofessional course of study. Continued development and refinement of the curriculum is planned to train the future rural healthcare workforce.Conclusions: Students from three health sciences colleges benefitted from the IPEC program with confirmed satisfaction in interprofessional rural education and collaborative practice. The addition of a rural nursing program merits continuation with modification and expansion to prepare the future rural interprofessional healthcare workforce.

description: Alnico is a prime example of a finely tuned nanostructure whose magnetic properties are intimately connected to magnetic annealing (MA) during spinodal transformation and subsequent lower temperature annealing (draw) cycles. Using a combination of transmission electron microscopy and atom probe tomography, we show how these critical processing steps affect the local composition and nanostructure evolution with impact on magnetic properties. The nearly 2-fold increase of intrinsic coercivity ($H_\text{ci}$) during the draw cycle is not adequately explained by chemical refinement of the spinodal phases. Instead, increased Fe-Co phase ($α_1$) isolation, development of Cu-rich spheres/rods/blades and additional $α_1$ rod precipitation that occurs during the MA and draw, likely play a key role in $H_\text{ci}$ enhancement. Chemical ordering of the Al-Ni-phase ($α_2$) and formation of Ni-rich ($α_3$) may also contribute. Unraveling of the subtle effect of these nano-scaled features is crucial to understanding on how to improve shape anisotropy in alnico magnets.

description: A study of the reactions pp -> pfps(K+K-pi+pi-) and pp -> pfps(K+K-pi+pi-pi0) shows evidence for the K*K* and phi omega channels respectively. The K*K* mass spectrum shows a broad distribution with a maximum near threshold and an angular analysis shows that it is compatible with having JP = 2+. The behaviour of the cross-section as a function of centre of mass energy, and the four momentum transfer dependence, are compatible with what would be expected if the K*K* system was produced via double Pomeron exchange. The dPT behaviour of the phi omega channel is similar to what has been observed for all the undisputed qqbar states. In contrast, the dPT behaviour of the K*K* final state is similar to what has been observed for the phi phi final state and for previously observed glueball candidates.

description: Computing size and credibility of Bayesian credible regions for certifying the reliability of any point estimator of an unknown parameter (such as a quantum state, channel, phase, \emph{etc.}) relies on rejection sampling from the entire parameter space that is practically infeasible for large datasets. We reformulate the Bayesian credible-region theory to show that both properties can be obtained solely from the average of log-likelihood over the region itself, which is computable with direct region sampling. Neither rejection sampling nor any geometrical knowledge about the whole parameter space is necessary, so that general error certification now becomes feasible. We take this region-average theory to the next level by generalizing size to the average $l_p$-norm distance $(p>0)$ between a random region point and the estimator, and present analytical formulas for $p=2$ to estimate distance-induced size and credibility for any physical system and large datasets, thus implying that asymptotic Bayesian error certification is possible without any Monte~Carlo computation. All results are discussed in the context of quantum-state tomography.

description: Pulsar timing array (PTA) provides an excellent opportunity to detect the gravitational waves (GWs) in nanoHertz frequency band. In particular, due to the larger number of "arms" in PTA, it can be used to test gravity by probing the non-Einsteinian polarization modes of GWs, including two spin-1 shear modes labeled by "$sn$" and "$se$", the spin-0 transverse mode labeled by "$b$" and the longitudinal mode labeled by "$l$". In this paper, we investigate the capabilities of the current and potential future PTAs, which are quantified by the constraints on the amplitudes parameters $(c_b,c_{sn},c_{se},c_{l})$, by observing an individual supermassive black hole binary in Virgo cluster. We find that for binary with chirp mass $M_{c}=8.77 \times 10^{8} \mathrm{M_{\odot}}$ and GW frequency $f=10^{-9}\mathrm{Hz}$, the PTA at current level can detect these GW modes if $c_b > 0.00106$, $c_l > 0.00217$, $c_{se} > 0.00271$, $c_{sn} > 0.00141$, which will be improved by about two orders if considering the potential PTA in SKA era. Interesting enough, due to effects of the geometrical factors, we find that in SKA era, the constraints on the $l$, $sn$, $se$ modes of GWs are purely dominated by several pulsars, instead of the full pulsars in PTA.

description: We examine a (3+1)-dimensional model of staggered lattice fermions with a four-fermion interaction and Z(2) chiral symmetry using the Hamiltonian formulation. This model cannot be simulated with standard fermion algorithms because those suffer from a very severe sign problem. We use a new fermion simulation technique - the meron-cluster algorithm - which solves the sign problem and leads to high-precision numerical data. We investigate the finite temperature chiral phase transition and verify that it is in the universality class of the 3-d Ising model using finite-size scaling.

description: Data from seven data storage tags recovered from Atlantic salmon marked as smolts were analyzed for depth movements and patterns of deep diving during the marine migration. The salmon mostly stayed at the surface and showed diurnal activity especially from autumn until spring. During the first months at sea the salmon stayed at shallower depths (< 100 m). The salmon took short deep dives (> 100 m), that were rare or absent during the first summer at sea but increased in frequency and duration especially in late winter. The maximum depth of the dives varied from 419 to 1187 m. Most of dives were short, (< 5 hours) but could last up to 33 hours. The duration of dives increased in late winter until spring and the overall depth and maximum depth per dive increased exponentially over time. The initiation of the dives was more common in evenings and at night, suggesting nocturnal diving. We hypothesized that deep diving is related to feeding of salmon as mesopelagic fish can be important food for salmon during winter.

Talking Culture: Women in the production of community in the northwest Amazon

description: Research article based on fieldwork in the Amazon basin of Brazil.
description: ABSTRACT Taking the Northwest Amazon of Brazil as its example, this article argues for the analytic concept of a “speech culture,” combining, but heuristically separating, speech practice and language ideology. In the Northwest Amazon, an ideology of language establishes an equivalence between linguistic performance and descent group belonging. In contrast to the fixed, normative notions of groupness, this article explores the dynamic construction of social relations through women’s ritualized wept greeting speech. In these interactions, linguistic differentiation is countered by the experience of a single speech act based upon shared principles with organized participation in and by different linguistic codes. Through the collaborative nature of the speech act a common ground is produced and revealed. The community in this sense emerges as a cultural artifact whose production is largely the work of women. Through these speech interactions—of similar sentiments and meanings across different linguistic codes—women of the Northwest Amazon construct a community of talk.

description: We present an enhanced version of the Zernike wavefront sensor, that simultaneously measures phase and amplitude aberrations. The 'vector-Zernike' wavefront sensor consists of a patterned liquid-crystal mask, which imposes $\pm π/2$ phase on the point spread function core through the achromatic geometric phase acting with opposite sign on opposite circular polarizations. After splitting circular polarization, the ensuing pupil intensity images are used to reconstruct the phase and the amplitude of the incoming wavefront. We demonstrate reconstruction of the complex wavefront with monochromatic lab measurements and show in simulation the high accuracy and sensitivity over a bandwidth up to $100\%$

description: Neste trabalho avaliamos quantitativamente o ruído e a relação sinal ruído (SNR) na visualização de microcalcificações em imagens mamográficas por dupla energia, empregando métodos numéricos. Foi simulado um exame de mamografia, utilizando a técnica de dupla energia, calculado o sinal gerado no detector e o ruído associado a esses sinais. Assim foi possível calcular o ruído nas imagens subtraídas para várias microcalcificações com diferentes espessuras, variando a distribuição da fração de Kerma incidente entre os feixes de alta e baixa energia. Em seguida foi calculado a SNR dessas imagens. Utilizando o critério de Rose, verificamos a menor espessura de microcalcificação que poderia ser detectada, tomando como limiar uma SNR igual a cinco. Os resultados mostram que frações do Kerma incidente para o feixe de baixa energia entre 0,3 e 0,7 produzem menor ruído na imagem. A SNR é menor para calcificações pequenas. A menor espessura de microcalcificação detectável nesta simulação foi de 300 μm, para uma mama de 5 cm de espessura comprimida e de composição 50% adiposa.

description: Standard Bayesian credible-region theory for constructing an error region on the unique estimator of an unknown state in general quantum-state tomography to calculate its size and credibility relies on heavy Monte~Carlo sampling of the state space followed by sample rejection. This conventional method typically gives negligible yield for very small error regions originating from large datasets. We propose an operational reformulated theory to compute both size and credibility from region-average quantities that in principle convey information about behavior of these two properties as the credible-region changes. We next suggest the accelerated hit-and-run Monte~Carlo sampling, customized to the construction of Bayesian error-regions, to efficiently compute region-average quantities, and provide its complexity estimates for quantum states. Finally by understanding size as the region-average distance between two states in the region (measured for instance with either the Hilbert-Schmidt, trace-class or Bures distance), we derive approximation formulas to analytically estimate both distance-induced size and credibility under the pseudo-Bloch parametrization without resorting to any Monte~Carlo computation.

description: We propose a phenomenological model of vortex dynamics in which the vortex is taken as a composite object made of two components: the vortex current which is massless and driven by the Lorentz force, and the vortex core which is massive and driven by the Magnus force. By combining the characteristics of the Gittleman-Rosenblum model (Phys. Rev. Lett. {\bf 16}, 734 (1966)) and Hsu's theory of vortex dynamics (Physica {\bf C 213},305 (1993)), the model provides a good description of recent far infrared measurements of the magneto-conductivity tensor of superconducting YBa$_2$Cu$_3$O$_{7-δ}$ films from 5 cm$^{-1}$ to 200 cm$^{-1}$.

Electron Glass in Ultrathin Granular Al Films at Low Temperatures

description: Quench-condensed granular Al films, with normal-state sheet resistance close to 10 k$Ω/\Box$, display strong hysteresis and ultraslow, non-exponential relaxation in the resistance when temperature is varied below 300 mK. The hysteresis is nonlinear and can be suppressed by a dc bias voltage. The relaxation time does not obey the Arrhenius form, indicating the existence of a broad distribution of low energy barriers. Furthermore, large resistance fluctuations, having a 1/f-type power spectrum with a low-frequency cut-off, are observed at low temperatures. With decreasing temperature, the amplitude of the fluctuation increases and the cut-off frequency decreases. These observations combine to provide a coherent picture that there exists a new glassy electron state in ultrathin granular Al films, with a growing correlation length at low temperatures.

description: In this contribution, we aim at investigating the mechanism of biosensing in graphene-based materials from first principles. Inspired by recent experiments, we construct an atomistic model composed of a pyrene molecule serving as a linker fragment, which is used in experiment to attach certain aptamers, and a defective zigzag graphene nanoribbons (ZGNRs). Density functional theory including dispersive interaction is employed to study the energetics of the linker absorption on the defective ZGNRs. Combining non-equilibrium Green's function and the Landauer formalism, the total current-bias voltage dependence through the device is evaluated. Modifying the distance between the linker molecule and the nanojunction plane reveals a quantitative change in the total current-bias voltage dependence, which correlates to the experimental measurements. In order to illuminate the geometric origin of these variation observed in the considered systems, the local currents through the device are investigated using the method originally introduced by Evers and co-workers. In our new implementation, the numerical efficiency is improved by applying sparse matrix storage and spectral filtering techniques, without compromising the resolution of the local currents. Local current density maps qualitatively demonstrate the local variation of the interference between the linker molecule and the nanojunction plane.

description: The data for this article is drawn from the research work on participatory epidemiology and gender in Ethiopia. The research project conducted focus group discussions (FGDs) and household survey in 2015 and 2016, respectively. Ninety-two focus group discussions were held with adult men and women, and youth male and female groups. In addition, a household survey from 646 respondents, 236 male household heads (36.5%), 88 women household heads (13.6%) and 322 women in male headed households (49.9%) were conducted. Using data on gender roles from the study we analysed gender differentials and the intensity of involvement of household members in small ruminant management and husbandry practices in the study sites. Our results suggest that all household members participate in the different small ruminant husbandry and management practices with varying degrees of involvement across agro-ecologies and from the perspectives of the different categories of respondents. Despite prevailing perceptions that women control small ruminants, men control the decision-making aspect of small ruminant husbandry and management practices whereas women are mainly responsible for executing all the husbandry related roles. Considering gendered perceptions about gender roles as well as agro-ecological dimensions, they potentially have important implications especially for the design of animal health interventions in the study areas.
