description: The Discrete Element Method (DEM) has been employed in recent years to simulate flexible protection structures undergoing dynamic loading due to its inherent aptitude for dealing with inertial effects and large deformations. The individual structural elements are discretized with an arbitrary number of discrete elements, connected by spring-like remote interactions. In this work, we implement this approach using the parallel bond contact model and compare the numerical results at different discretization intervals with the analytical solutions of classical beam theory. Successively, we use the same model to simulate the punching test of a steel wire mesh and quantify the influence of a different number of elements on the macroscopic response.

description: We investigate the macroscopic and microscopic physical properties of the solid solution of Ce$_{1-x}$Pr$_{x}$AlGe. The series tunes from CeAlGe with its multi-$\vec{k}$ structure and a major Moment in the ab-plane, to PrAlGe with an easy-c-axis ferromagnetic ground state co-existing with a low density of nanoscale textured magnetic Domain walls. Using AC-, DC-susceptiblity, resistivity, specific heat, muon spin relaxation/rotation and neutron scattering we analyze the magnetic ground state of the series. We provide further evidence supporting our previous claim for spin-glass like properties in pure PrAlGe. With introduction of Pr to CeAlGe the finite magnetic field required to stabilize the topological multi-$\vec{k}$ magnetic phase for $x=0$ becomes suppressed. The crossover between the two end-member ground states occurs in the vicinity of $x=0.3$, a region where we further anticipate the field-induced topological magnetic phase for $x < 0.3$ to become the zero field ground state.

description: Our 2005 Physical Review Letter entitled "Suppression of Spin-Projection Noise in Broadband Atomic Magnetometry" (volume 94, 203002) relied heavily in its claims of experimental quantum-limited performance on the results of a prior publication from our group [1]. In subsequent work we have determined that the results of [1] were incorrect and must therefore retract this Physical Review Letter as well. The authors would like to emphasize that the broadband magnetometry approach taken in our work remains valid, as described in the theoretical paper [2], but we have lost confidence in the calibration procedures employed at the time to establish sensitivity relative to the spin-projection noise level.

description: In this work we studied the two-dimensional ionization structure of the circumnuclear and extranuclear regions in a sample of six low-z Ultraluminous Infrared Galaxies using Integral Field Spectroscopy. The ionization conditions in the extranuclear regions of these galaxies (~5-15 kpc) are typical of LINERs as obtained from the Veilleux-Osterbrock line ratio diagnostic diagrams. The range of observed line ratios is best explained by the presence of fast shocks with velocities of 150 to 500 km s^{-1}, while the ionization by an AGN or nuclear starburst is in general less likely. The comparison of the two-dimensional ionization level and velocity dispersion in the extranuclear regions of these galaxies shows a positive correlation, further supporting the idea that shocks are indeed the main cause of ionization. The origin of these shocks is also investigated. Despite the likely presence of superwinds in the circumnuclear regions of these systems, no evidence for signatures of superwinds such as double velocity components are found in the extended extranuclear regions. We consider a more likely explanation for the presence of shocks, the existence of tidally induced large scale gas flows caused by the merging process itself, as evidenced by the observed velocity fields characterized by peak-to-peak velocities of 400 km s^{-1}, and velocity dispersions of up to 200 km s^{-1}.

description: The global expansion of biobanks has led to a range of bioethical concerns related to consent, privacy, control, ownership, and disclosure. As an opportunity to engage broader audiences on these concerns, bioethicists have welcomed the commercial success of Rebecca Skloot’s 2010 bestselling book The Immortal Life of Henrietta Lacks. To assess the impact of the book on discussion within the media and popular culture more generally, we systematically analyzed the ethics-related themes emphasized in reviews and articles about the book, and in interviews and profiles of Skloot.

description: We try to introduce heavy flavors to Sakai-Sugimoto model by regarding higher dimensional components of gauge fields as heavy mesons. Using the Forgács and Manton approach, we obtain a theory composed of heavy mesons and the instanton of light flavors. Applying the collective coordinate quantization method, we derived a mass formula of heavy baryons. In the leading order of $1/m_{H}$ expansion ($m_{H}$ the mass of a heavy quark), we find singlet and doublet states in the heavy quark symmetry (HQS). Also, we obtain the degenerate Roper like and odd parity excitations. By virtue of heavy meson degrees of freedom, our mass formula reproduces the mass ordering of $Σ^*_c$ and $Λ_c^*$ correctly.

description: We provide the first large field investigation of more than 20 gold deposits and sites along the Keraf suture zone, covering an area of ~15,000 km2. The area shows diverse structural settings for gold mineralization in greenschist, amphibolite, and hornfels metamorphosed rocks. The reverse fault and dyke-hosted settings appear to be the most favourable for forming gold deposits. Two major N-S-trending, ~300-km-long corridors of deformation are delineated (West and East) but only the West seems important for gold. From fluid inclusions, 6 types of fluids are distinguished based on specific volatile contents and proportions. Most types can be related to fluid evolution by hydrothermal reactions and phase separations from a primitive fluid of metamorphic origin, containing H2O, CO2, N2, CH4, C2H6, and H2. Regional hydrothermal fields are identified based on the combinations of structural settings and fluid types. The northern field is defined as a single large hydrothermal system accounting for the mineralization of the 3 gold deposits (WG-03, UTM and Central). For sites along the West Corridor, such as Toubi, Anas, NW and Shereik, multiple and overlapping hydrothermal systems are necessary to explain the various fluid types and structural settings, even at the deposit scale (Shereik). Conversely, other sites (SW, Yasmine, Korup, Saijd, Dardora, Negeim, and SE) formed by localized individual hydrothermal systems. The documentation of fluids containing ethane at numerous sites and deposits is the most significant outcome. Such ethane-bearing fluids are generated by the metamorphism of carbonaceous-pyritic sedimentary rocks. These rocks are considered one of the best sources for providing ligands and gold for the formation of orogenic gold deposits. Consequently, the Keraf suture zone, composed mainly of carbonaceous turbidites, is interpreted to have provided such source rocks in the suture zone and below the adjacent cratons during the collision, forming orogenic gold deposits (graphical abstract).

description: The combined cooling, heating and power (CCHP) system is a typical distributed, electricity-gas integrated energy scheme in a community. First, it generates electricity by use of gas, and then exploits the waste heat to supply community with heat and cooling. In this paper, we consider a smart city consisting of a number of communities (CCHPs) and an agent of power grid (APG), where CCHPs can sell energy to the APG according to its bid. To study all utilities of entities in such a city from energy trading, a noncooperative Stackelberg game between APG and CCHPs is formulated. Here, the APG gives a bid for buying the energy from CCHPs, then CCHPs respond to the APG with their optimal energy supply that maximizing their utilities according to this bid. We show that the maximum profit to the APG and utilities to the CCHPs can be obtained at the Stackelberg equilibrium, which is guaranteed to exist and unique. Because the complete information about energy supply of each CCHP is unknown to the APG in advance, we propose a distributed algorithm that is able to find the point of equilibrium through a limited number of iterations. Taking privacy protection and transaction security into consideration, we design a blockchain-enabled energy management system. This system is composed of Internet of Energy (IoE) sub-system and blockchain sub-system, where the information interactions as well as energy transactions between APG and CCHPs can be carried out effectively and safely. Finally, security analysis and numerical simulations show the effectiveness and accuracy of our proposed mechanism.

description: The large-scale search for high-performing candidate 2D materials is limited to calculating a few simple descriptors, usually with first-principles density functional theory calculations. In this work, we alleviate this issue by extending and generalizing crystal graph convolutional neural networks to systems with planar periodicity, and train an ensemble of models to predict thermodynamic, mechanical, and electronic properties. To demonstrate the utility of this approach, we carry out a screening of nearly 45,000 structures for two largely disjoint applications: namely, mechanically robust composites and photovoltaics. An analysis of the uncertainty associated with our methods indicates the ensemble of neural networks is well-calibrated and has errors comparable with those from accurate first-principles density functional theory calculations. The ensemble of models allows us to gauge the confidence of our predictions, and to find the candidates most likely to exhibit effective performance in their applications. Since the datasets used in our screening were combinatorically generated, we are also able to investigate, using an innovative method, structural and compositional design principles that impact the properties of the structures surveyed and which can act as a generative model basis for future material discovery through reverse engineering. Our approach allowed us to recover some well-accepted design principles: for instance, we find that hybrid organic-inorganic perovskites with lead and tin tend to be good candidates for solar cell applications.

description: We report on the status of primordial nucleosynthesis in light of recent results on CMB anisotropies from WMAP experiment. Theoretical estimates for nuclei abundances, along with the corresponding uncertainties, are evaluated using a new numerical code, where all nuclear rates usually considered have been updated using the most recent available data. Moreover, additional processes, neglected in previous calculations, have been included. The combined analysis of CMB and primordial nucleosynthesis prediction for Deuterium gives an effective number of relativistic degrees of freedom in good agreement with the simplest scenario of three non degenerate neutrinos. Our findings seem to point out possible systematics affecting 4He mass fraction measurements, or the effect of exotic physics, like a slightly degenerate relic neutrino background.

Electoral laws and turnout, 1972-2008
Creators: name: Leighley, Jan
name: Nagler, Jonathan
Publisher: name: American University
Year: 2023

description: In this paper we examine the impact of electoral laws on overall turnout, and class bias in the electorate. Using turnout in each state in each year we use cross sectional time series analysis to estimate the impact of electoral reforms on turnout, with particular attention to the discriminatory impact of legal changes on persons at different segments of the income distribution. This gives us much more powerful estimates of these effects than were previously available. We do not suffer from the problems of cross-sectional analyses which rely on the assumption that the choice of electoral regime is independent of the likelihood of voting. And by using all presidential elections from 1972 thru 2008 we have much more statistical power than has been provided by previous analyses simply looking at difference of means tests across two elections. We consider the impact of: the number of days prior to election day that registration closes; the availability of election day registration; the availability of no-excuse early voting, and the availability of no-fault absentee voting. We show the net effects of these reforms on the probability of individuals voting, and we calculate the effect on at-risk votes and show that more poorly educated voters are not necessarily those more likely to take advantage of electoral reforms.

description: We take advantage of the capabilities of the OTELO survey to select and study the AGN population in the field. We performed an analysis of the properties of these objects, including their demography, morphology, and IR luminosity. Focusing on the population of H$α$ emitters at $z \sim 0.4$, we also aim to study the environments of AGN and non-AGN galaxies at that redshift. We make use of the multiwavelength catalog of objects in the field compiled by the OTELO survey, unique in terms of minimum line flux and equivalent width. The OTELO pseudo-spectra allow the identification of emission lines and the spectral classification of the sources. We obtained a sample of 72 AGNs in the field of OTELO, selected with four different methods in the optical, X-rays, and mid-infrared bands. We find that using X-rays is the most efficient way to select AGNs. An analysis was performed on the AGN population of OTELO in order to characterize its members. At $z \sim 0.4$, we find that up to 26\% of our H$α$ emitters are AGNs. At that redshift, AGNs are found in identical environments to non-AGNs, although they represent the most clustered group when compared to passive and star-forming galaxies. The majority of our AGNs at any redshift were classified as late-type galaxies, including a 16\% proportion of irregulars. Another 16\% of AGNs show signs of interactions or mergers. Regarding the infrared luminosity, we are able to recover all the luminous infrared galaxies (LIRGs) in the field of OTELO up to $z\sim 1.6$. We find that the proportion of LIRGs and ultra-luminous infrared galaxies (ULIRGs) is higher among the AGN population, and that ULIRGs show a higher fraction of AGNs than LIRGs.

description: Two electron interference experiments which are far from each other are considered. They are irradiated with correlated nonclassical electromagnetic fields, produced by the same source. The phase factors are in this case operators, and their expectation values with respect to the density matrix of the electromagnetic field quantify the observed electron fringes. The correlated photons create correlations between the observed electron intensities. Both cases of classically correlated (separable) and quantum mechanically correlated (entangled) electromagnetic fields are considered. It is shown that the induced correlation between the distant electron interferences is sensitive to the nature of the correlation between the irradiating photons.

description: This paper describes a study of the lower Jurassic conglomerates in the region around Lake Baikal (Irkutsk and Chita Oblasts, Buryat Republic). The approach used in the study was the analysis of samples from well cores, outcrops, and mine workings. Lithological and geochemical analyses of the conglomerate’s matrices suggest that the conglomerates were deposited in a single early Jurassic river paleo-valley, the geological structure of which was later complicated by tectonic processes. The most significant results of this were the formation of the Angara-Selenga imbricate-fan thrust and the Baikal rift basin. The position of the Praselenga River valley was reconstructed for the first time. It is noted that gold-bearing Lower Jurassic conglomerates are represented by mineralogical association resistant to weathering processes formed in the mountain valleys.
Mixing and Decoherence in Continuous-Time Quantum Walks on Cycles

description: We prove analytical results showing that decoherence can be useful for mixing time in a continuous-time quantum walk on finite cycles. This complements the numerical observations by Kendon and Tregenna (Physical Review A 67 (2003), 042315) of a similar phenomenon for discrete-time quantum walks. Our analytical treatment of continuous-time quantum walks includes a continuous monitoring of all vertices that induces the decoherence process. We identify the dynamics of the probability distribution and observe how mixing times undergo the transition from quantum to classical behavior as our decoherence parameter grows from zero to infinity. Our results show that, for small rates of decoherence, the mixing time improves linearly with decoherence, whereas for large rates of decoherence, the mixing time deteriorates linearly towards the classical limit. In the middle region of decoherence rates, our numerical data confirms the existence of a unique optimal rate for which the mixing time is minimized.

In this article, the two co-editors offer some reflections on the value of the text to scholars, especially those interested in the history of Cumberland and Westmorland in the 17th century. They contend that the leitmotif of Fleming's life and work was his quest for order, as seen in his strict supervision of his family, his firm hand as a magistrate, and his systematic cataloguing of the history and antiquities of his region.

description: Shape optimization studies how to design a domain such that a shape function is minimized. Ubiquitous in industrial applications, shape optimization is often constrained to partial differential equations (PDEs). One of the main challenges in PDE-constrained shape optimization is the coupling of domain updates and PDE-solvers. Fireshape addresses this challenge by elegantly coupling the finite element library Firedrake and the Rapid Optimization Library (ROL). The main features of Fireshape are: accessibility to users with minimal shape optimization knowledge; decoupled discretization of control and state variables; full access to Firedrake's PDE-solvers; automated derivation of adjoint equations and shape derivatives; different metrics to define shape gradients; access to ROL's optimization algorithms via PyROL. Fireshape is available at https://github.com/fireshape/fireshape. Fireshape's documentation comprises several tutorials and is available at https://fireshape.readthedocs.io/en/latest/.

description: We report on the realization of an optical phase noise cancellation technique by passively embedding the optical phase information into a radio frequency (RF) signal and shifting the optical frequency with the amount of phase noise introduced by optical phase perturbations. Neither phase discrimination nor active phase tracking is required due to the open-loop design, mitigating some technical problems, such as the limited compensation speed and the finite phase/timing jitter, in conventional phase noise cancellation. We experimentally demonstrate that this technique maintains the same delay-limited bandwidth and phase noise suppression capability as in conventional techniques, but significantly shortens the response speed and phase recovery time. Passive decoupling optical phase perturbation represents a powerful technique in the domains of optical frequency standard comparisons and clockworks for future optical atomic clocks, which are now under serious investigation for a potential redefinition of the International Time Scale.

description: Sustainable business models also offer banks competitive advantages such as increasing brand reputation and cost reduction. However, no framework is presented to evaluate the sustainability of banking business models. To bridge this theoretical gap, the current study using A Delphi-Analytic Hierarchy Process method, firstly, developed a sustainable business model to evaluate the sustainability of the business model of banks. In the second step, the sustainability performance of sixteen banks from eight European countries including Norway, the UK, Poland, Hungary, Germany, France, Spain, and Italy, assessed. The proposed business model components of this study were ranked in terms of their impact on achieving sustainability goals. Consequently, the proposed model components of this study, based on their impact on sustainability, are respectively value proposition, core competencies, financial aspects, business processes, target customers, resources, technology, customer interface, and partner network. The results of the comparison of the banks studied by each country disclosed that the sustainability of the Norwegian and German banks business models is higher than in other counties. The studied banks of Hungary and Spain came in second, the banks of the UK, Poland, and France ranked third, and finally, the Italian banks ranked fourth in the sustainability of their business models.

description: In this paper we examine the impact of electoral laws on overall turnout, and class bias in the electorate. We look at the impact of changes in registration laws on who votes, with particular attention to the discriminatory impact of legal changes on persons at different segments of the income distribution. By aggregating turnout for different demographic groups – persons with different levels of education and income – by state, and then pooling those state level turnout rates over time, we can use cross sectional time series analysis to estimate the impact of electoral reforms. This gives us much more powerful estimates of these effects than were previously available. We do not suffer from the problems of cross-sectional analyses which rely on the assumption that the choice of electoral regime is independent of the likelihood of voting. And by using all presidential elections from 1972 thru 2004 we have much more statistical power than has been provided by previous analyses simply looking at difference of means tests across two elections. We consider the impact of: the number of days prior to election day that registration closes; the availability of election day registration; the availability of early voting, and the availability of absentee voting.

description: The success of Convolutional Neural Networks (CNNs) in image classification has prompted efforts to study their use for classifying image data obtained in Particle Physics experiments. Here, we discuss our efforts to apply CNNs to 2D and 3D image data from particle physics experiments to classify signal from background. In this work we present an extensive convolutional neural architecture search, achieving high accuracy for signal/background discrimination for a HEP classification use-case based on simulated data from the Ice Cube neutrino observatory and an ATLAS-like detector. We demonstrate among other things that we can achieve the same accuracy as complex ResNet architectures with CNNs with less parameters, and present comparisons of computational requirements, training and inference times.

Effects of intermediate bound states in dynamic force spectroscopy

description: We revisit here some aspects of the interpretation of dynamic force spectroscopy experiments. The standard theory predicts a typical unbinding force $f^*$ linearly proportional to the logarithm of the loading rate $r$ when a single energetical barrier controls the unbinding process; for a more complex situation of $N$ barriers, it predicts at most $N$ linear segments for the $f^*$ vs. $\log(r)$ curve, each segment characterizing a different barrier. We here extend this existing picture using a refined approximation, we provide a more general analytical formula, and show that in principle up to $N(N+1)/2$ segments can show up experimentally. As a consequence the interpretation of data can be ambiguous, for the characteristics and even the number of barriers. A further possible outcome of a multiple-barrier landscape is a bimodal or multimodal distribution of the unbinding force at a given loading rate, a feature recently observed experimentally.

title: Characterisation of the rif and stevor Multigene Families in Plasmodium falciparum Isolates Sampled From Natural Infections

description: Parasite-derived variant surface antigens (VSA) expressed on the infected erythrocyte surface are important targets of naturally acquired protective immune responses against malaria. The three major VSA-encoding multigene families of Plasmodium falciparum, var, rif and stevor, exhibit high inter- and intra-strain genomic variability. The VSA component encoded by the var gene family, PfEMP1, comprises the major cytoadhesive ligand and the major antigenic target of protective antibodies. However, other VSA families, including those encoded by the rif and stevor multigene families, may also play important roles in malaria pathogenesis and immunity. However, the biological relevance of non-PfEMP1 VSA remains largely unknown.

This thesis represents the first extensive analysis of sequence diversity and expression patterns of rif and stevor variant gene families in African field isolates of P. falciparum. The work details the characterization of rif and stevor gene repertoires of P. falciparum parasites from diverse geographical locations and identification of conserved genes in both P. falciparum and the related chimpanzee malaria parasite P. reichenowi.

Both capillary sequencing and clone-free, 454 deep sequencing methods have been used to study changes in variant gene expression during asexual development of wild and culture-adapted isolates. Isolate- and stage-specific transcription patterns of rif and stevor genes were observed, and the major sets of transcripts in multiple isolates, including parasites that have been selected for different cytoadhesive phenotypes (resetting and adhesion to human brain endothelial cell lines) identified.

The role of RIFIN antigens in the natural acquisition of antibodies to malaria was tested using a strain transcendent variant PF3D7_1253700 (PFL2585c). The hypervariable region of this RIFIN, expressed as a recombinant protein was used to purify naturally acquired human antibodies from sera from malaria-immune African adults. These antibodies recognized native RIFIN antigen on the surface of intact trophozoites showing that RIFINs for additional targets of naturally acquired antibodies that recognize the surface of parasite-infected red blood cells.

description: Ethiopia’s agricultural sector accounts to 40 percent of national Gross Domestic Product. This shows that the sector is important in improving the livelihoods of the bulk of the population. Despite its importance, the agricultural sector in Ethiopia is characterized by low productivity. To improve this and overall economic growth, the Ethiopian government has focused on promotion of organic fertilizer use. However, adoption of organic fertilizer remains low in most parts of Ethiopia including Shashemene district. This study therefore aimed at identifying the major constraints of organic fertilizer adoption and its income effect with specific objectives being determining transaction costs associated with adoption of organic fertilizer, factors influencing adoption and use intensity and impact of organic fertilizer use on households’ farm income. The study used primary data which was collected from 368 smallholder farmers. The analytical framework incorporated descriptive statistics, double hurdle model and propensity score matching. The results showed that the average transaction costs through bargaining, searching for information and transportation were 68.23 ETB, 53.33 ETB and 124.53 ETB respectively. Policing and enforcement costs were non-existent among the farmers. The household size, livestock number, extension contacts, access to information media and membership to farmer groups significantly influenced the decision to adopt organic fertilizer. The farm income, size of the cultivated plot, membership to farmer groups and application frequency of organic fertilizer significantly influenced the intensity of organic fertilizer use. Propensity score matching revealed that the adoption of organic fertilizer increased farmers per hectare farm income by between 2661 ETB and 2959 ETB. Thus, farmers should be encouraged to adopt organic fertilizer. This could be possible if the government and other stakeholders gave more attention to provision of better extension services and better access to information related to organic fertilizer adoption as well as making availability of this fertilizer to farmers easier.

Electoral reform, party mobilization, and voter turnout

description: In this paper we explore the conditions under which candidates and party officials use electoral reforms (i.e., early voting) to mobilize voters. We draw upon a unique database that studies a sample of registered voters and matches their validated voting behavior with partisan campaign activities in each voter's respective county during the 2002 midterm election in Texas. We expect, first, that considerations of strategy and opportunity shape both parties' use of early voting to mobilize supporters and second, that the impact of their efforts on voter turnout is mediated by these elite strategies. Our empirical evidence supports our central thesis: without the efforts of political parties and their candidates, electoral reforms are likely to have a marginal effect on voter turnout. An important modification to our original thesis, however, is that the effectiveness of electoral reforms is dependent not only on whether political elites choose to take advantage of such rules in developing their electoral strategies, but also on party members' initial probability of voting absent any mobilization, a key feature distinguishing the effectiveness of Republican and Democratic mobilization efforts.
