description: We adopt the notion of von Neumann-Morgenstern farsightedly stable sets to predict which matchings are possibly stable when agents are farsighted in one-to-one matching problems. We provide the characterization of von Neumann-Morgenstern farsightedly stable sets: a set of matchings is a von Neumann-Morgenstern farsightedly stable set if and only if it is a singleton set and its element is a corewise stable matching. Thus, contrary to the von Neumann-Morgenstern (myopically) stable sets, von Neumann-Morgenstern farsightedly stable sets cannot include matchings that are not corewise stable ones. Moreover, we show that our main result is robust to many- to-one matching problems with responsive preferences.

description: Having unique data we investigate the link between job separations (displacement and quits) and informal employment, which we define in several ways posing the general question whether the burden of informality falls disproportionately on job separators in the Russian labor market. After we have established positive causal effects of displacement and quits on informal employment we analyze whether displaced workers experience more involuntary informal employment than their non-displaced counterparts. Our main results confirm our contention that displacement entraps some of the workers in involuntary informal employment. Those who quit, in turn, experience voluntary informality for the most part, but there seems a minority of quitting workers who end up in involuntary informal jobs. This scenario does not fall on all the workers who separate but predominantly on workers with low human capital. We also pursue the issue of informality persistence and find that informal employment is indeed persistent as some workers churn from one informal job to the next. Our study contributes to the debate in the informality literature regarding segmented versus integrated labor markets. It also contributes to the literature on displacement by establishing informal employment as an important cost of displacement. We also look at the share of undeclared wages in formal jobs and find that these shares are larger for separators than for incumbents, with displaced workers bearing the brunt of this manifestation of informality.

description: We consider a spinless $t$-$t'$ ionic Hubbard chain at 1/2 filling and large hopping ratio $t'/t$. In this limit the model adequately maps onto a weakly coupled triangular ladder with a potential interchain bias. The low-energy properties of the system are formed due to the interplay of geometrical frustration, correlations and charge imbalance. We derive the effective field-theoretical model to study universal properties of the model in the scaling limit. We show that at full dynamical frustration the ground state of the ladder represents a repulsive version of the Luther-Emery liquid with dominant orbital antiferromagnetic correlations exhibiting the slowest power-law decay in the ground state. Pairing correlations also display algebraic order but are subdominant. At an incomplete dynamical frustration a finite commensurability gap is dynamically generated, and the fluctuating OAF transforms to a long-range ordered state with a spontaneously broken time reversal symmetry. The mass gap in the spectrum of relative density fluctuations gets suppressed upon increasing the potential bias.

description: Public pension systems based on the Notional Defined Contribution (NDC) principle were introduced during the ‘90s in Italy, Sweden and Poland, among other countries. They mimic private savings, in that individuals get back, as pensioners, what they contributed to social security during working life, plus returns. As such, NDC systems should realize actuarial equity and incentive neutrality. However, when one considers the presence of NDC pensions together with minimum and social assistance pensions, this is no longer true. Indeed, in all the three countries considered, the NDC system shows a regressive feature, which disincentives contributions, particularly from low earners, who would be better off entering, or staying in, the shadow economy. In order to reduce the extent of this phenomenon, we examine the effects of introducing, or increasing, the possibility of accumulation of social assistance and NDC pensions, which would also improve pension adequacy. A complete accumulation of the two would solve the incentive problem, but would be costly and would require a structural reform of the pension system financing mechanism, altering the current balance between social contributions and general fiscal revenues. We show the effects of a change in the accumulation rules for social assistance and NDC pensions in Italy using CAPP DYN, a population-based dynamic micro simulation model, which allows assessment of the evolution of the pension system in the coming decades and the distributional implications of such reform.

description: Although highly adaptable, leopards incur substantial mortality in human-modified landscapes and generally subsist at lower densities than in protected areas. Leopard populations are difficult to enumerate across any landscapes, though there have been strides to improve upon this, particularly in South Africa. This study aimed to determine the population density of leopards in the Magaliesberg mountain range of the North West province in 2015 and provided a longitudinal comparison of these camera-trapping sites. It appraises the efficacy of interventions aimed at improving the status quo of zero leopards found during a prior survey in 2011. Such interventions included a moratorium on sport hunting of the species, and the reintroduction of four individuals, two of each sex, into this area. Camera trapping over 10 months detected seven unique individuals, including one juvenile and six adults, consisting of four males and three females, half of which were previously reintroduced or progeny thereof. A Bayesian capture-recapture abundance model indicated a population of 5–7 individuals occurring within 1 480 km2 of available habitat, yielding a density estimate of 0.34–0.47 adult leopards per 100 km2, which is a relatively low estimate, likely due to population suppression from anthropogenic pressures surrounding the site (i.e., snaring). This study demonstrates that large carnivore populations can recolonise their former range via targeted interventions within topographical refugia.

description: We adopt a stepwise approach to the analysis of a dynamic oligopoly game in which production makes use of a natural resource and pollutes the environment, starting with simple models where firms' output is not a function of the natural resource to end up with a full-fledged model in which (i) the resource is explicitly considered as an input of production and (ii) the natural resource and pollution interact via the respective state equations. This allows us to show that the relationship between the welfare properties of the economic system and the intensity of competition is sensitive to the degree of accuracy with which the model is constructed.

description: Turbulence in the intracluster, intragroup, and circumgalactic medium plays a crucial role in the self-regulated feeding and feedback loop of central supermassive black holes. We dissect the three-dimensional turbulent `weather' in a high-resolution Eulerian simulation of active galactic nucleus (AGN) feedback, shown to be consistent with multiple multi-wavelength observables of massive galaxies. We carry out post-processing simulations of Lagrangian tracers to track the evolution of enstrophy, a proxy of turbulence, and its related sinks and sources. This allows us to isolate in depth the physical processes that determine the evolution of turbulence during the recurring strong and weak AGN feedback events, which repeat self-similarly over the Gyr evolution. We find that the evolution of enstrophy/turbulence in the gaseous halo is highly dynamic and variable over small temporal and spatial scales, similar to the chaotic weather processes on Earth. We observe major correlations between the enstrophy amplification and recurrent AGN activity, especially via its kinetic power. While advective and baroclinc motions are always sub-dominant, stretching motions are the key sources of the amplification of enstrophy, in particular along the jet/cocoon, while rarefactions decrease it throughout the bulk of the volume. This natural self-regulation is able to preserve, as ensemble, the typically-observed subsonic turbulence during cosmic time, superposed by recurrent spikes via impulsive anisotropic AGN features (wide outflows, bubbles, cocoon shocks). This study facilitates the preparation and interpretation of the thermo-kinematical observations enabled by new revolutionary X-ray IFU telescopes, such as XRISM and Athena.

description: USDA’s current method for estimating expected counter-cyclical payment rates produces unintentionally biased estimates because it does not consider the variability of marketing year prices. Estimates with positive bias increase the risk of overpayment to producers who accept advance payments. According to statute, producers must reimburse the Government for any overpayments, which can lead to cash-flow problems. A model developed for this analysis improved upon the USDA method of estimating counter-cyclical payment rates by accounting for the variability in market price forecast errors. This enhanced method produced unbiased estimates. Forecasters and producers can also use the model to calculate the probabilities of repayment. Producers can use call options on commodity futures contracts to hedge against losses in expected counter-cyclical payments. Hedging, however, is only moderately effective and varies by commodity.

description: We consider the optimal trade execution strategies for a large portfolio of single stocks proposed by Almgren (2003). This framework accounts for a nonlinear impact of trades on average market prices. The execution strategy of Almgren (2003) is based on the assumption that no shares per unit of time are trade at the beginning of the period. We use a general solution method that accomodates the case of positive initial trades. Our results are twofold. First of all, we show that the problem admits a solution with no trading in the opening period only if additional parametric restrictions are imposed. Second, with positive initial trading, the optimal execution time depends on trading activity in the initial period.

description: We perform a thorough analysis of the projected shapes of nearby galaxies in both observations and cosmological simulations. We implement a forward-modeling approach to overcome the limitations in previous studies, which hinder accurate comparisons between observations and simulations. We measure axis ratios of $z=0$ (snapshot 99) TNG50 galaxies from their synthetic Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP) images and compare them with those obtained from real HSC-SSP images of a matched galaxy sample. Remarkably, the comparison shows excellent agreement between the observations and the TNG50 simulation, challenging previous claims that $Λ$CDM models underproduced the abundance of thin galaxies. Specifically, for galaxies with stellar masses $10\leq \log (M_{\star}/M_{\odot}) \leq 11.5$, we find $\lesssim 0.1σ$ tensions between the observations and the simulation, a stark contrast to the previously reported $\gtrsim 10σ$ tensions. We reveal that low-mass galaxies ($M_{\star}\lesssim 10^{9.5}\,M_{\odot}$) in TNG50 are thicker than their observed counterparts in HSC-SSP and attribute this to the spurious dynamical heating effects that artificially puff up galaxies. We also find that, despite the overall broad agreement, TNG50 galaxies are more concentrated than the HSC-SSP ones at the low- and high-mass end of the stellar mass range of $9.0\leq \log (M_{\star}/M_{\odot}) \leq 11.2$ and are less concentrated at intermediate stellar masses. But we argue that the higher concentrations of the low-mass TNG50 galaxies are not likely the cause of their thicker/rounder appearances. Our study underscores the critical importance of conducting mock observations of simulations and applying consistent measurement methodologies to facilitate proper comparison with observations.

description: We show that scanning gate microscopy can be used for probing electron-electron interactions inside a nanostructure. We assume a simple model made of two non-interacting strips attached to an interacting nanosystem. In one of the strips, the electrostatic potential can be locally varied by a charged tip. This change induces corrections upon the nanosystem Hartree-Fock self-energies which enhance the fringes spaced by half the Fermi wavelength in the images giving the quantum conductance as a function of the tip position.

description: The robustness of topological materials against disorder and defects is presumed but has not been demonstrated explicitly in realistic systems. In this work, we use state-of-the-art density functional theory and recursive nonequilibrium Green's functions methods to study the effect of disorder in the electronic transport of long nanoribbons, up to 157 nm, as a function of vacancy concentration. In narrow nanoribbons, even for small vacancy concentrations, defect-like localized states give rise to hybridization between the edge states erasing topological protection and enabling backscattering events. We show that the topological protection is more robust for wide nanoribbons, but surprisingly it breaks down at moderate structural disorder. Our study helps to establish some bounds on defective bismuthene nanoribbons as promising candidates for spintronic applications.

description: Increasing beach sediment loss from erosion and high levels of crab Ocypode spp. predation are threatening turtle nests and nesting habitat. The 900 m long beach on Cousine Island, Seychelles, supports a nesting population of approximately 70–130 hawksbill turtle Eretmochelys imbricata nests each season. Seasonal and storm-related erosion and accretion cycles on Cousine Island have the potential of destroying 50% or more of all turtle egg clutches on the island in a single nesting season. Observed crab predation rates had reached 90–100% in preferred nesting beach zones in previous years. This has resulted in intensive management measures to minimise turtle egg and nest losses. We investigated the distribution and population density of ghost crabs and the morphology of the beach across the different beach area zones and across the turtle-nesting season during 2014–2015. Crab burrow numbers varied between beach zone areas and across the season and were highest on the backshore. Crab density correlated negatively with available beach area, and we found that crab density increased in the presence of turtle nests. When examining beach dynamics, we found them to be cyclical and found the nesting beach prone to higher levels of erosion than accretion with significant changes in beach width throughout the season. The mean vertical beach elevation drop on Cousine Island was higher than what hawksbill turtles have been reported to prefer. We suggest the continuation of beach elevation monitoring and management to use the beach morphology data to assist with hawksbill turtle nest translocations to minimise nest losses and maximise hatchling recruitment success.

description: This report examines current trends in the U.S. grain industry. Many identity preservation(IP) grain systems have emerged recently, driven by a confluence of supply and demand factors. IP grain requirements for specific production protocols, marketing channels, and quality assurance depend on whether the crops are trait-specific, non-GM (genetically modified), organic, or pharmaceutical. Cost structures vary according to the relative importance of segregation and risk management. High information management, greater market coordination, and frequent reliance on contracts characterize IP grains. IP grain markets are also inherently riskier, with volatile supply, inelastic demand, and fluctuating price premiums. Increasing grain differentiation is altering the marketing structure of the U.S. grain industry and creating possible roles for government policy, particularly in market facilitation, standard setting, and regulations affecting food safety and biosecurity.

We derive the SN Ia rate as a function of redshift under a theoretical context for the production of first generation stars and emanate the likelihood of their detection by the James Webb Space Telescope (JWST).} {Assuming the initial stellar mass function (IMF) favors low-mass stars as from recent numerical simulations, we found Pop III stars may give rise to a considerable amount of SNe Ia at high redshift and Pop III stars may even be the dominant SN Ia producer at z $\gtrsim 6$.} {In an optimistic scenario, we expect $\sim 1(2)$ SNe Ia from Pop III stars at $z\approx 4(5)$ for a survey of area $300 \;\rm arcmin^2$ during a $3\;\rm yr$ period with JWST. The same survey may record more than $\sim 400$ SNe Ia at lower redshift ($z\lesssim 2.5$) but with only about one of them from Pop III progenitors. There will be $\sim 6$ Pop III SNe Ia in the same field of view at redshifts of $5-10$.} Observational constraints on SN Ia rates at the redshift range of $5-10$ can place crucial constraints on the IMF of Pop III stars.

Fast Rydberg gates without dipole blockade via quantum control

description: We propose a scheme for controlling interactions between Rydberg-excited neutral atoms in order to perform a fast high-fidelity quantum gate. Unlike dipole-blockade mechanisms already found in the literature, we drive resonantly the atoms with a state-dependent excitation to Rydberg levels, and we exploit the resulting dipole-dipole interaction to induce a controlled atomic motion in the trap, in a similar way as discussed in recent ion-trap quantum computing proposals. This leads atoms to gain the required gate phase, which turns out to be a combination of a dynamic and a geometrical contribution. The fidelity of this scheme is studied including small anharmonicity and temperature effects, with promising results for reasonably achievable experimental parameters.

description: Climate-related hazards, urban development and changing vulnerability patterns compel cities across the world to deal with new and emerging forms of risk. Academic literature and recent international policy documents suggest potentials of conceptually and practically linking the fields of climate change adaptation (CCA) and disaster risk reduction (DRR) and emphasize the need to mitigate climate-related risks at local level. However, there is limited knowledge on how this link is established at local levels and the role of ground-level actors and practices therein. Using the case of recurrent and disastrous floods, this paper discusses the significance of linking DRR and CCA in Mumbai. It analyses policies, plans, institutions and interventions related to DRR and CCA and uses interviews and a field study to assess flood risk governance at the level of municipal wards and neighbourhoods. The findings suggest that although flood risk governance has been significantly strengthened, three gaps exist: First, a lack of a comprehensive plan for Mumbai that anticipates future risks and vulnerabilities and integrates CCA and DRR down to local level. Second, a lack of an overarching and decentralized institutional framework across sectors and scales that recognizes the multiplicity of formal and informal actors. Third, the potential of civil society and informal actors for disaster risk management and adaptation planning has not been tapped into sufficiently. The paper argues that potential exists to reconceptualize flood risk governance in Mumbai by focusing on future risks and vulnerabilities and by recognizing the work of informal actors like emergent groups at local level.

description: We simulate a model of repulsively interacting colloids on a commensurate two-dimensional triangular pinning substrate where the amount of heterogeneous motion that appears at melting can be controlled systematically by turning off a fraction of the pinning sites. We correlate the amount of heterogeneous motion with the average topological defect number, time dependent defect fluctuations, colloid diffusion, and the form of the van Hove correlation function. When the pinning sites are all off or all on, the melting occurs in a single step. When a fraction of the sites are turned off, the melting becomes considerably broadened and signatures of a two-step melting process appear. The noise power associated with fluctuations in the number of topological defects reaches a maximum when half of the pinning sites are removed, and the noise spectrum has a pronounced 1/f^αstructure in the heterogeneous regime. We find that regions of high mobility are associated with regions of high dislocation densities.

description: When subjects interact in continuous time, their ability to cooperate may dramatically increase. In an experiment, we study the impact of different time horizons on cooperation in (quasi) continuous time prisoner's dilemmas. We find that cooperation levels are similar or higher when the horizon is deterministic rather than stochastic.

Moreover, a deterministic duration generates different aggregate patterns and individual strategies than a stochastic one. For instance, under a deterministic horizon subjects show high initial cooperation and a strong end-of-period reversal to defection. Moreover, they do not learn to apply backward induction but to postpone defection closer to the end.

description: Ion trap is one of the most promising candidates for quantum computing. Current schemes mainly focus on a linear chain of up to about one hundred ions in a Paul trap. To further scale up the qubit number, one possible direction is to use 2D or 3D ion crystals (Wigner crystals). In these systems, ions are generally subjected to large micromotion due to the strong fast-oscillating electric field, which can significantly influence the performance of entangling gates. In this work, we develop an efficient numerical method to design high-fidelity entangling gates in a general 3D ion crystal. We present numerical algorithms to solve the equilibrium configuration of the ions and their collective normal modes. We then give a mathematical description of the micromotion and use it to generalize the gate scheme for linear ion chains into a general 3D crystal. The involved time integral of highly oscillatory functions is expanded into a fast-converging series for accurate and efficient evaluation and optimization. As a numerical example, we show a high-fidelity entangling gate design between two ions in a 100-ion crystal, with a theoretical fidelity of 99.9\%.

description: The primary thrust of tissue engineering is the clinical translation of scaffolds and/or biologics to reconstruct tissue defects. Despite this thrust, clinical translation of tissue engineering therapies from academic research has been minimal in the 27 year history of tissue engineering. Academic research by its nature focuses on, and rewards, initial discovery of new phenomena and technologies in the basic research model, with a view towards generality. Translation, however, by its nature must be directed at specific clinical targets, also denoted as indications, with associated regulatory requirements. These regulatory requirements, especially design control, require that the clinical indication be precisely defined a priori, unlike most academic basic tissue engineering research where the research target is typically open-ended, and furthermore requires that the tissue engineering therapy be constructed according to design inputs that ensure it treats or mitigates the clinical indication. Finally, regulatory approval dictates that the constructed system be verified, i.e., proven that it meets the design inputs, and validated, i.e., that by meeting the design inputs the therapy will address the clinical indication. Satisfying design control requires (1) a system of integrated technologies (scaffolds, materials, biologics), ideally based on a fundamental platform, as compared to focus on a single technology, (2) testing of design hypotheses to validate system performance as opposed to mechanistic hypotheses of natural phenomena, and (3) sequential testing using in vitro, in vivo, large preclinical and eventually clinical tests against competing therapies, as compared to single experiments to test new technologies or test mechanistic hypotheses. Our goal in this paper is to illustrate how design control may be implemented in academic translation of scaffold based tissue engineering therapies. Specifically, we propose to (1) demonstrate a modular platform approach founded on 3D printing for developing tissue engineering therapies and (2) illustrate the design control process for modular implementation of two scaffold based tissue engineering therapies: airway reconstruction and bone tissue engineering based spine fusion.

description: A Bayesian optimization algorithm for the nurse scheduling problem is presented, which involves choosing a suitable scheduling rule from a set for each nurses assignment. Unlike our previous work that used Gas to implement implicit learning, the learning in the proposed algorithm is explicit, ie. Eventually, we will be able to identify and mix building blocks directly. The Bayesian optimization algorithm is applied to implement such explicit learning by building a Bayesian network of the joint distribution of solutions. The conditional probability of each variable in the network is computed according to an initial set of promising solutions. Subsequently, each new instance for each variable is generated, ie in our case, a new rule string has been obtained. Another set of rule strings will be generated in this way, some of which will replace previous strings based on fitness selection. If stopping conditions are not met, the conditional probabilities for all nodes in the Bayesian network are updated again using the current set of promising rule strings. Computational results from 52 real data instances demonstrate the success of this approach. It is also suggested that the learning mechanism in the proposed approach might be suitable for other scheduling problems.
Relationship between ischaemia-selective drug action and antiarrhythmic efficacy

description: This thesis explores the relationship between the electrophysiological actions of drugs on ischaemic myocardial tissue and their effects on arrhythmias induced by ischaemia. Our hypothesis was that drugs with ischaemia-selective electrophysiological actions would provide better antiarrhythmic protection in the setting of acute myocardial ischaemia than those which lacked such selectivity. The actions of a selection of standard antiarrhythmic drugs (quinidine, lidocaine, flecainide and tedisamil) were compared to those of the novel drug RSD1019, under conditions designed to mimic, or produce, myocardial ischaemia in rat hearts. In support of the hypothesis, drugs which exhibited selectivity for the conditions of myocardial ischaemia (i.e., lidocaine and RSD1019) suppressed ischaemia-induced arrhythmias effectively. Drugs that were more potent in normal myocardial tissue, and which lacked such selectivity (i.e., quinidine, flecainide and tedisamil), were less effective for suppression of ischaemia-induced arrhythmias. Further studies were carried out in order to evaluate the hypothesis using monophasic action potential (MAP) recordings from the epicardium of anaesthetised rabbits before and after induction of myocardial ischaemia. The advantage offered by this preparation was that it allowed the electrophysiological changes caused by ischaemia, and drug effects thereon, to be assessed simultaneously with arrhythmias resulting from myocardial ischaemia. In this preparation, both RSD1019 and lidocaine influenced the electrophysiological properties of ischaemic tissue and arrhythmias but in different ways. Lidocaine exacerbated the electrophysiological derangement caused by ischaemia and had proarrhythmic actions. RSD1019 prevented MAP shortening caused by ischaemia and arrhythmias. In contrast to RSD1019, the IK(ATP> blocker glibenclamide failed to prevent MAP shortening caused by ischaemia and the antiarrhythmic effects produced by this drug are unlikely to be related to its effects on ischaemic myocardial tissue. In summary, ischaemia-selective drug actions have the same potential benefits and risks associated with drug action in normal myocardial tissue. The action of a drug on ischaemic tissue can be pro- or antiarrhythmic depending on the nature of the drug's action and other factors that remain to be identified. Prolongation of action potential duration in ischaemic tissue, demonstrated herein for RSD1019, was associated with antiarrhythmic actions. This mechanism represents a novel approach to suppression of ischaemia-induced arrhythmias.

description: Research on performative teaching has expanded in recent decades. This growth has been accompanied by interest in evidence-based practice and evaluation. However, experimentation is complex and classroom-based researchers must carefully and responsibly negotiate many obstacles. Despite challenges inherent in this endeavour, many practitioners are genuinely interested in how and why theatre supports learning. In this article we explore experimentation in the second language classroom and outline a conceptual framework which embeds qualitative data collection within an experimental design. These ideas can be regarded as an extensive case study that combines and furthers the work of teacher artists and scientific practice.

description: In the Western Indian Ocean (WIO), more than 76 records from peer-reviewed and grey literature identified approximately 60 invertebrate taxa harvested for bait and food. The most diverse phyla were Mollusca, followed by Arthropoda and Annelida, with few records of Porifera, Nemertea and Echinodermata. Importance of each phylum differs according to country, with arthropods (Upogebia africana and Kraussillichirus kraussi), and annelids (Marphysa mossambica) being most important in South Africa and Kenya, respectively. Of the taxa utilised, only 42 are reliably identified to species level, suggesting that the diversity of species utilised in the region is greatly underestimated. Most of the data on biology and exploitation were for species from South Africa. Less data were available from Kenya with minimal to none being available from the remaining WIO countries. This limits the understanding of biology and trends in exploitation of most bait taxa, and consequently information required for developing national and regional management policies. Bait management guidelines are available only for South Africa, but require updating in view of changes in use of bait resources. We recommend the development of coordinated multidisciplinary, multicountry research aimed at increasing data and information to feed into policy development and support national and regional bait resource management.

description: This paper investigates the effects of board of director collusion on managerial incentives and firm values. Recent academic research hints at the social network of board of directors as an important conduit for coordinating corporate governance policies, such as managerial pay, and curbing competition. We study a model where managers can exert unobservable cost-cutting effort and investigate the consequences of and the incentives for coordinating managerial pay among corporate boards.
