description: Since the beginning of the new millennium, stock markets went through every state from long-time troughs, trade suspensions to all-time highs. The literature on asset pricing hence assumes random processes to be underlying the movement of stock returns. Observed procyclicality and time-varying correlation of stock returns tried to give the apparently random behavior some sort of structure. However, common misperceptions about the co-movement of asset prices in the years preceding the \emph{Great Recession} and the \emph{Global Commodity Crisis}, is said to have even fueled the crisis' economic impact. Here we show how a varying macroeconomic environment influences stocks' clustering into communities. From a sample of 296 stocks of the S\&P 500 index, distinct periods in between 2004 and 2011 are used to develop networks of stocks. The Minimal Spanning Tree analysis of those time-varying networks of stocks demonstrates that the crises of 2007-2008 and 2010-2011 drove the market to clustered community structures in both periods, helping to restore the stock market's ceased order of the pre-crises era. However, a comparison of the emergent clusters with the \textit{General Industry Classification Standard} conveys the impression that industry sectors do not play a major role in that order.

description: We study three different types of local quenches (local operator, splitting and joining) in both the free fermion and holographic CFTs in two dimensions. We show that the computation of a quantity called entanglement density, provides a systematic method to capture essential properties of local quenches. This allows us to clearly understand the differences between the free and holographic CFTs as well as the distinctions between three local quenches. We also analyze holographic geometries of splitting/joining local quenches using the AdS/BCFT prescription. We show that they are essentially described by time evolutions of boundary surfaces in the bulk AdS. We find that the logarithmic time evolution of entanglement entropy arises from the region behind the Poincare horizon as well as the evolutions of boundary surfaces. In the CFT side, our analysis of entanglement density suggests such a logarithmic growth is due to initial non-local quantum entanglement just after the quench. Finally, by combining our results, we propose a new class of gravity duals, which are analogous to quantum circuits or tensor networks such as MERA, based on the AdS/BCFT construction.

Bistability in thermomechanical metamaterials structured as three-dimensional composite tetrahedra

Year: 2021
Subjects: Uncategorized

description: The letter begins with the thermomechanical model of a three degree-of-freedom tetrahedral unit cell subject to cycles of heating and cooling. Geometric nonlinearity, mechanical constraint and dissimilar material properties of thermoelastic elements lead to a build-up of thermally-driven stored strain energy as dictated by the thermomechanical potential. For certain geometric configurations and combinations of material properties in the composite structure, the solution bifurcates at a critical thermal load causing a discontinuous buckling or ‘pop-through’ of the interior triad. Interestingly, if the pop-through action coincides with an abrupt inward displacement of the tetrahedral vertices then the effective volume of the unit cell shrinks. The phenomenon is termed negative ‘intermittent’ volumetric thermal expansion. In total, six types of thermal load–response curves are identified. By systematic nonlinear analysis of the thermomechanical potential, the stability diagram and phase diagram pinpoint the locations of bifurcations, cusps and features that mark a shifts in hysteretic behavior. The diagrams map the thermomechanical response to the design of the unit cell. A region is identified in the phase diagram corresponding to the sets of design parameters that lead to the metamaterial response.

description: Coupling nanocrystals (quantum dots) to a high-$Q$ whispering gallery mode (WGM) of a silica microsphere, can produce a strong coherent interaction between the WGM and the electronic states of the dots. Shifting the resonance frequencies of the dots, for instance by placing the entire system in an electric potential, then allows this interaction to be controlled, permitting entangling interactions between different dots. Thus, this system could potentially be used to implement a quantum computer.

Results, directly applicable to experiments on cuprates, reveal on doping a very pronounced increase of the width of the two-magnon Raman peak, accompanied by a decrease of the total intensity. At the same time the peak position does not shift substantially in the underdoped regime.

description: Using the formalism of supersymmetric quantum mechanics, we obtain a large number of new analytically solvable one-dimensional periodic potentials and study their properties. More specifically, the supersymmetric partners of the Lame potentials ma(a+1)sn^2(x,m) are computed for integer values a=1,2,3,.... For all cases (except a=1), we show that the partner potential is distinctly different from the original Lame potential, even though they both have the same energy band structure. We also derive and discuss the energy band edges of the associated Lame potentials pm sn^2(x,m)+qm cn^2(x,m)/ dn^2(x,m), which constitute a much richer class of periodic problems. Computation of their supersymmetric partners yields many additional new solvable and quasi exactly solvable periodic potentials.

Particle acceleration and fast magnetic reconnection

Year: 2019
Subjects: subject: Plasma Physics (physics.plasm-ph)

description: Mathematics demonstrates that an ideally evolving magnetic field has an exponentially increasing sensitivity to non-ideal effects for all but truly exceptional evolutions. On a time scale that depends only logarithmically on the magnitude of non-ideality, an evolving magnetic field will generally reach a state of fast magnetic reconnection. The effects of fast magnetic reconnection proceed at a rate determined by Alfvénic, not resistive, physics. The best known of these effects are associated with the transfer of magnetic field energy to the plasma and the conservation of magnetic helicity, which limits the energy transfer. As will be shown, weak non-ideality implies helicity conservation in regions bounded by magnetic surfaces or rigid perfect conductors. But, weak non-ideality makes the rapid transfer of energy subtle. This transfer can be understood by the drive for Alfvén waves and two other effects, which are present even in an ideal evolution, an effective parallel electric field $\mathcal{E}_{||}$, which can accelerate particles despite the particle acceleration due to the true parallel electric field $E_{||}$ being negligible, and a coefficient $ν_K$, which gives a rate for exponentiation of the kinetic energy of particle motion along the magnetic field. Classical theories of reconnection are two-dimensional and exclude the exponentially increasing sensitivity that is robustly present for magnetic fields in three-dimensional space.
Go-Go music and place identity: the perseverance of the Chocolate City
Creators: name: Hall, Adriana
Publisher: name: No Publisher Supplied
Year: 2021

description: Washington, D.C. has two sides: Washington and D.C. Washington is a melting pot with powerful leaders and newcomers working their way through the political scene. D.C., or The Chocolate City, is a space for Black people by Black people. It has a unique culture that sets trends in fashion, dance, and music. Unfortunately, gentrification in the city is diminishing D.C.’s Black population, giving way to physical and cultural displacement. This thesis analyzes how the identity and sound of D.C. as represented through Go-Go music, is a catalyst for organization and activism in response to intense development pressures. It also explores streets in D.C. as public spaces that activate public awareness and response. The analysis and exploration are guided by the following questions:How can music show Black people how to exist outside of their pain?How can design include self-identity or place identity in a landscape?These questions will be answered through a reflection of current events, historical research, and musical mapping. Through an analysis of the history of Black music, from enslavement to Go-Go, this thesis illustrates how music is a form of unrestrained expression and empowerment. This history validates music as a documentation of place identity and as an activism tool to gather and strengthen communities. The main vehicle for this activism is the street, which through different methods of design, can be manipulated to support resilient placemaking.A documentary (https://youtu.be/Zofs34FaS-0) was produced as a means to convey the exploration into music and place identity. Through the use of archival material, spatial genre mapping, and the development of a template for music genres, this accompanying visual component allows for an ephemeral analysis on place and how its identity can develop over time. It views Washington, D.C. through the first-person lens while simultaneously explaining the found research. In addition, a design toolkit that includes the parameters of modularity, display of historical and cultural identity, a space for performance and artistic freedom, and a network of history are the building blocks to help create resilient Black spaces that support activism in the landscape.

description: We improve a lattice model of water introduced by Sastry, Debenedetti, Sciortino, and Stanley to give insight on experimental thermodynamic anomalies in supercooled phase, taking into account the correlations between intra-molecular orientational degrees of freedom. The original Sastry et al. model including energetic, entropic and volumic effect of the orientation-dependent hydrogen bonds (HBs), captures qualitatively the experimental water behavior, but it ignores the geometrical correlation between HBs. Our mean-field calculation shows that adding these correlations gives a more water-like phase diagram than previously shown, with the appearance of a solid phase and first-order liquid-solid and gas-solid phase transitions. Further investigation is necessary to be able to use this model to characterize the thermodynamic properties of the supercooled region.

description: We address the stability issue of Ricci-flat and maximally symmetric spacetimes in nonlocal gravity to all perturbative orders in the gravitational perturbation. Assuming a potential at least cubic in curvature tensors but quadratic in the Ricci tensor, our proof consists on a mapping of the stability analysis in nonlocal gravity to the same problem in Einstein-Hilbert theory. One of the consequences is that only the graviton field can propagate and the theory is ghost-free at all perturbative orders. All the results known in Einstein gravity in vacuum with or without a cosmological constant can be exported to the case of nonlocal gravity: if a spacetime is stable at all perturbative orders in Einstein gravity, it is stable also in nonlocal gravity. Minkowski and de Sitter spacetimes are particular examples. We also study how the theory affects the propagation of gravitational waves in a cosmological background.

description: Several agri-food studies have been done to promote African Indigenous Vegetables (AIVs) with food and nutrition security being a major promoting factor. However, practices of preparation, cooking and sharing a meal have been less studied thus creating a missing link in agri-food studies. This paper seeks to reveal the socio-cultural practices of consumption of AIVs in Kenyan households. The paper introduces the innovative concept of meal security. Qualitative studies were conducted in Nairobi, Nakuru and Kakamega regions in Kenya between 2015 and 2017. Results revealed that consumption of AIVs in Kenyan households is highly gendered. Women are responsible for most of the tasks in relation to AIV preparation and cooking. However, women also use their agency to circumvent some of the challenges they face including choice of family meals and a time burden. The paper recommends strategies and innovations that can reduce these challenges including reduction in time for cooking, provision of infrastructure and challenging conventional gender norms.

description: We discuss the large scale effective potential for elastic objects (manifolds) in the presence of a random pinning potential, from the point of view of the Functional Renormalisation Group (FRG) and of the replica method. Both approaches suggest that the energy landscape at large scales is a succession of parabolic wells of random depth, matching on singular points where the effective force is discontinuous. These parabolas are themselves subdivided into smaller parabolas, corresponding to the motion of smaller length scales, in a hierarchical manner. Consequences for the dynamics of these pinned objects are underlined.

We find that in the high-temperature limit the imaginary part of the self-energy is given by the classical theory to leading order in the coupling. In particular the plasmon damping rate is a purely classical effect to leading order, as shown by Aarts and Smit. The dominant contribution to Landau damping is given by the propagation of classical fields in a heat bath of non-interacting fields.

description: The aim of this study is to evaluate the performance of water-saving technologies (WST) through an investigation of its effect at the farm level. Indeed, the study attempts to estimate the economic value of WST use in Algerian farming, through the comparison of some farm performance indicators between WST adopters, drip irrigation system as a WST, and farmers practicing gravity irrigation as a traditional system. A cross-section data from a survey is conducted in an irrigated perimeter situated in the north-eastern Algeria (Jijel region) encompassing 106 small horticultural farms (including 60 pepper producers and 46 tomato producers). First, the study compares some performance indicators between the two groups of farms. Second, a stochastic production frontier model is used to estimate the productivity gain generated by the WST adoption. Main results show that water consumption, gross margin, and water productivity are statistically significant between the two groups of farms. The average water productivity differential between WST users and non-users is 29% and 25% for tomato and pepper, respectively. The regression model has shown that increasing the WST use by 1% help to increase water productivity of the region by 0.20% for pepper production and 0.11% for tomato production. The findings of this study confirm the hypothesis that WST economize on water quantity, positively affects crop yield and can enhance water productivity.

Anomalous strain energy transformation pathways in mechanical metamaterials

Publisher: name: University of Illinois at Chicago
Year: 2021
Subjects: Uncategorized

description: This discussion starts with a mechanics version of Parseval's energy theorem applicable to any discrete lattice material with periodic internal structure: a microtruss, grid, frame, origami or tessellation. It provides a simple relationship between the strain energy volumetric/usual and spectral distributions in the reciprocal space. The spectral energy distribution leads directly to a spectral entropy of lattice deformation (Shannon's type), whose variance with a material coordinate represents the decrease of information about surface loads in the material interior. Spectral entropy is also a basic measure of complexity of mechanical responses of metamaterials to surface and body loads. Considering transformation of the energy volumetric and spectral distributions with a material coordinate pointed away from a surface load, several interesting anomalies are seen even for simple lattice materials, when compared to continuum materials. These anomalies include selective filtering of surface Raleigh waves (sinusoidal pressure patterns), Saint-Venant effect inversion illustrated by energy spectral distribution contours, occurrence of 'hiding pockets' of low deformation, and redirection of strain energy maximum away from axis of a concentrated surface load. The latter phenomenon can be significant for impact protection applications of mechanical metamaterials.

Solid waste is unwanted material generated from combined residential, industrial, and commercial activities in a given area. Since landfills are permanent sites, they need special attention in selecting the location by applying an efficient method. This study employed the Fuzzy logic in combination with Weighted Linear Combination (WLC) methods for the selection of solid waste landfill site in Shashemene town. Moreover, the study used multi-criteria decision-making integrated with Geographic Information System (GIS) to evaluate solid waste site.

Topological superconductivity in planar Josephson junctions: Narrowing down to the nanowire limit

description: We theoretically study topological planar Josephson junctions (JJs) formed from spin-orbit-coupled two-dimensional electron gases (2DEGs) proximitized by two superconductors and subjected to an in-plane magnetic field $B_\parallel$. Compared to previous studies of topological superconductivity in these junctions, here we consider the case where the superconducting leads are narrower than the superconducting coherence length. In this limit the system may be viewed as a proximitized multiband wire, with an additional knob being the phase difference $ϕ$ between the superconducting leads. A combination of mirror and time-reversal symmetry may put the system into the class BDI. Breaking this symmetry changes the symmetry class to class D. The class D phase diagram depends strongly on $B_{\parallel}$ and chemical potential, with a weaker dependence on $ϕ$ for JJs with narrower superconducting leads. In contrast, the BDI phase diagram depends strongly on both $B_\parallel$ and $ϕ$. Interestingly, the BDI phase diagram has a "fan"-shaped region with phase boundaries which move away from $ϕ= π$ linearly with $B_\parallel$. The number of distinct phases in the fan increases with increasing chemical potential. We study the dependence of the JJ's critical current on $B_\parallel$, and find that minima in the critical current indicate first-order phase transitions in the junction only when the spin-orbit coupling strength is small. In contrast to the case of a JJ with wide leads, in the narrow case these transitions are not accompanied by a change in the JJ's topological index. Our results, calculated using realistic experimental parameters, provide guidelines for present and future searches for topological superconductivity in JJs with narrow leads, and are particularly relevant to recent experiments [A. Fornieri et al., Nature (London) 569, 89 (2019)].

description: We explore signals of new physics with two Higgs bosons and large missing transverse energy at the LHC. Such a signature is characteristic of models for dark matter or other secluded particles that couple to the standard model through an extended scalar sector. Our goal is to provide search strategies and an interpretation framework for this new signature that are applicable to a large class of models. To this end, we define simplified models of hidden sectors leading to two different event topologies: symmetric decay, i.e., pair-produced mediators decaying each into a Higgs plus invisible final state; and di-Higgs resonance, i.e., resonant Higgs-pair production recoiling against a pair of invisible particles. For both scenarios, we optimize the discovery potential by performing a multi-variate analysis of final states with four bottom quarks and missing energy, employing state-of-the-art machine learning algorithms for signal-background discrimination. We determine the parameter space that the LHC can test in both scenarios, thus facilitating an interpretation of our results in terms of complete models. Di-Higgs production with missing energy is competitive with other missing energy searches and thus provides a new opportunity to find hidden particles at the LHC.

description: We consider a model for the formation of a river network in which erosion process plays a role only at the initial stage. Once a global connectivity is achieved, no further evolution takes place. In spite of this, the network reproduces approximately most of the empirical statistical results of natural river network. It is observed that the resulting network is a spanning tree graph and therefore this process could be looked upon as a new algorithm for the generation of spanning tree graphs in which different configurations occur quasi-randomly. A new loop-less percolation model is also defined at an intermediate stage of evolution of the river network.

description: This study analyzes entropy collapse leading to black hole formation and identifies stability conditions for exotic gravitational objects. Our simulation results demonstrate a strong correlation between the parameters (α,β,λ) and the rate of entropy decay, with specific threshold values determining whether a system collapses into a black hole or stabilizes as an exotic remnant. The Schwarzschild radius variations and entropy stability conditions are also evaluated.

description: Sparse representation based classification (SRC) methods have achieved remarkable results. SRC, however, still suffer from requiring enough training samples, insufficient use of test samples and instability of representation. In this paper, a stable inverse projection representation based classification (IPRC) is presented to tackle these problems by effectively using test samples. An IPR is firstly proposed and its feasibility and stability are analyzed. A classification criterion named category contribution rate is constructed to match the IPR and complete classification. Moreover, a statistical measure is introduced to quantify the stability of representation-based classification methods. Based on the IPRC technique, a robust tumor recognition framework is presented by interpreting microarray gene expression data, where a two-stage hybrid gene selection method is introduced to select informative genes. Finally, the functional analysis of candidate's pathogenicity-related genes is given. Extensive experiments on six public tumor microarray gene expression datasets demonstrate the proposed technique is competitive with state-of-the-art methods.

description: The purpose of this study is to identify and measure the impact of various factors that affect the economic performance of micropolitan statistical areas in the U.S. Specifically, it is hypothesized that micropolitan area economic growth is highly related to locational amenities, primarily the housing supply and the regulatory environment. The Glaeser and Tobio (2008) growth model is used to obtain estimates for the amenity growth effect, productivity growth effect, and the housing supply growth effect for a cross-section of micropolitan statistical areas for the 1990-2010 period. A proxy variable for the regulatory environment is also developed. The findings indicate that a flexible housing supply and regulatory environment are significant determinants of the growth of micropolitan areas during the period under study.
Multi-Jet Event Rates in Deep Inelastic Scattering and Determination of the Strong Coupling Constant
Creators: name: Adloff, C.
Publisher: name: arXiv
Year: 1998
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: Jet event rates in deep inelastic ep scattering at HERA are investigated applying the modified JADE jet algorithm. The analysis uses data taken with the H1 detector in 1994 and 1995. The data are corrected for detector and hadronization effects and then compared with perturbative QCD predictions using next-to-leading order calculations. The strong coupling constant alpha_S(M_Z^2) is determined evaluating the jet event rates. Values of alpha_S(Q^2) are extracted in four different bins of the negative squared momentum transfer~$\qq$ in the range from 40 GeV2 to 4000 GeV2. A combined fit of the renormalization group equation to these several alpha_S(Q^2) values results in alpha_S(M_Z^2) = 0.117+-0.003(stat)+0.009-0.013(syst)+0.006(jet algorithm).

description: We demonstrate a fast numerical method of theoretical studies of skyrmion lattice or spiral order in magnetic materials with Dzyaloshinsky-Moriya interaction. The method is based on the Fourier expansion of the magnetization combined with a minimization of the free energy functional of the magnetic material in Fourier space, yielding the optimal configuration of the system for any given set of parameters. We employ a Lagrange multiplier technique in order to satisfy micromagnetic constraints. We apply this method to a system that exhibits, depending on the parameter choice, ferromagnetic, skyrmion lattice, or spiral (helical) order. Known critical fields corresponding to the helical-skyrmion as well as the skyrmion-ferromagnet phase transitions are reproduced with high precision. Using this numerical method we predict new types of excited (metastable) states of the skyrmion lattice, which may be stabilized by coupling the skyrmion lattice with a superconducting vortex lattice. The method can be readily adapted to other micromagnetic systems.

description: The aim of the study was to identify determinants of smallholder fruit commercialization in southwest Ethiopia. To get the sampled respondents multi-stage sampling techniques were used and in view of that, three districts were selected purposively from Jimma zone by selecting eight kebeles randomly. At the end, total of 240 sample households were randomly selected from these kebeles. To answer the research questions and objective of the study both qualitative and quantitative data were collected from primary and secondary sources. The primary data were collected from fruit producers as sampled households, agricultural experts, local leaders and other subject matter specialists on various aspects of commercializing fruits. Primary data were collected from the respondents using a pre-testing questionnaires, structured interview schedule and closed and open-ended questionnaires by well-trained enumerators closely supervised by the researchers. Secondary data were previous research findings and reports collected from kebeles, districts, agricultural offices, ministry of trade, trade and revenue offices. Moreover, qualitative data were collected through discussions with different agents by using focus group discussion and key informant interviews. The collected data were analysed using descriptive statistics (frequency, percentage, average mean, standard deviation, chi square and t-test) and econometric model (Probit model) to analyse determinant factors affecting smallholder’s participation decision in marketing of fruits. From the result, age of household heads, household family size, access to transport services, off-farm activities, access to extension services, distance to market, improved fruit seeds and perishability of fruit were significantly affecting smallholder farmer’s participation decision in commercialization of fruits. Therefore, to overcome the investigated problems strong commitment and reformation should be done by stakeholders including farmers, extension agents, researchers, policy makers.

A quantum Monte Carlo study of the one-dimensional ionic Hubbard model

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: Quantum Monte Carlo methods are used to study a quantum phase transition in a 1D Hubbard model with a staggered ionic potential (D). Using recently formulated methods, the electronic polarization and localization are determined directly from the correlated ground state wavefunction and compared to results of previous work using exact diagonalization and Hartree-Fock. We find that the model undergoes a thermodynamic transition from a band insulator (BI) to a broken-symmetry bond ordered (BO) phase as the ratio of U/D is increased. Since it is known that at D = 0 the usual Hubbard model is a Mott insulator (MI) with no long-range order, we have searched for a second transition to this state by (i) increasing U at fixed ionic potential (D) and (ii) decreasing D at fixed U. We find no transition from the BO to MI state, and we propose that the MI state in 1D is unstable to bond ordering under the addition of any finite ionic potential. In real 1D systems the symmetric MI phase is never stable and the transition is from a symmetric BI phase to a dimerized BO phase, with a metallic point at the transition.
