description: It has often been stated that current studies aimed at understanding the magnitude of optimal climate policy fail to adequately capture the potential for “catastrophic” impacts of climate change. While economic modeling exercises to date do provide evidence that potential climate catastrophes might significantly influence the optimal path of abatement, there is a need to move beyond experiments which are abstracted from important details of the climate problem in order to substantively inform the policy debate. This paper provides a foundation for improving the economic modeling of potential large scale impacts of climate change in order to understand their influence on estimates of socially efficient climate policy. We begin by considering how the term “catastrophic impacts” has been used in the scientific literature to describe changes in the climate system and carefully review the characteristics of the events that have been discussed in this context. We contrast those findings with a review of the way in which the economic literature has modeled the potential economic and human welfare impacts of events of this nature. We find that the uniform way in which the economic literature has typically modeled such impacts along with the failure to understand differences in the end points and timescales examined by the natural science literature has resulted in the modeling of events that do not resemble those of concern. Based on this finding and our review of the scientific literature we provide a path forward for better incorporating these events into integrated assessment modeling, identifying areas where modeling could be improved even within current modeling frameworks and others where additional work is needed.

description: IIB is a blind, humor-based computational change agent, which is made for emergence of hybrid, experimental collaboration forms of professionals, who can behave as independent professionals, authors of collaborations, and their members. By applying humor, IIB shows to the users, if they have honestly graded the jokes, how they naturally perceive clashes and fracture under uncertainty, common in the processes of change and sudden hair-raising transformation events, when experimenting is the way to change the status-quo and achieve. Also, when the users are clustered in collaborations, IIB shows them a diversity of their qualities and needs as a group in situations of fracture, clash, experiment, and high uncertainty. IIB disrupts comfort zones and conventional ways of decision making by providing challenge, ease, and support. IIB delivers change agents. Everybody can become a change agent for any group of people. Attached is the GENERAL INSTRUCTION on how to use IIB.

description: For a stochastic COVID-19 model with jump-diffusion, we prove the existence and uniqueness of the global positive solution. We also investigate some conditions for the extinction and persistence of the disease. We calculate the threshold of the stochastic epidemic system which determines the extinction or permanence of the disease at different intensities of the stochastic noises. This threshold is denoted by $ξ$ which depends on the white and jump noises. The effects of these noises on the dynamics of the model are studied. The numerical experiments show that the random perturbation introduced in the stochastic model suppresses disease outbreaks as compared to its deterministic counterpart. In other words, the impact of the noises on the extinction and persistence is high. When the noise is large or small, our numerical findings show that the COVID-19 vanishes from the population if $ξ<1;$ whereas the epidemic can't go out of control if $ξ>1.$ From this, we observe that white noise and jump noise have a significant effect on the spread of COVID-19 infection, i.e., we can conclude that the stochastic model is more realistic than the deterministic one. Finally, to illustrate this phenomenon, we put some numerical simulations.

description: We determine the universal law for fidelity decayin quantum computations of complex dynamics in presenceof internal static imperfections in a quantum computer. Our approach is based on random matrix theory applied toquantum computations in presence of imperfections.The theoretical predictions are tested and confirmed in extensive numerical simulations of a quantum algorithm for quantum chaos in the dynamical tent map with up to 18 qubits. The theory developed determines the time scales forreliable quantum computations in absence of the quantum error correction codes. These time scales are related to the Heisenberg time, the Thouless time, and the decay time given by Fermi's golden rule which are well known in the context of mesoscopic systems. The comparison is presented for static imperfection effects and random errors in quantum gates. A new convenientmethod for the quantum computation of the coarse-grained Wigner function is also proposed.

description: Product reviews are extremely valuable for online shoppers in providing purchase decisions. Driven by immense profit incentives, fraudsters deliberately fabricate untruthful reviews to distort the reputation of online products. As online reviews become more and more important, group spamming, i.e., a team of fraudsters working collaboratively to attack a set of target products, becomes a new fashion. Previous works use review network effects, i.e. the relationships among reviewers, reviews, and products, to detect fake reviews or review spammers, but ignore time effects, which are critical in characterizing group spamming. In this paper, we propose a novel Markov random field (MRF)-based method (ColluEagle) to detect collusive review spammers, as well as review spam campaigns, considering both network effects and time effects. First we identify co-review pairs, a review phenomenon that happens between two reviewers who review a common product in a similar way, and then model reviewers and their co-review pairs as a pairwise-MRF, and use loopy belief propagation to evaluate the suspiciousness of reviewers. We further design a high quality yet easy-to-compute node prior for ColluEagle, through which the review spammer groups can also be subsequently identified. Experiments show that ColluEagle can not only detect collusive spammers with high precision, significantly outperforming state-of-the-art baselines --- FraudEagle and SpEagle, but also identify highly suspicious review spammer campaigns.

description: The impacts on biodiversity and ecosystems are among the key reasons for concern about climate change. Integrated assessment models are the main tools used to estimate the global economic benefits of policies that would address climate change, but these models typically include only a partial accounting and idiosyncratic treatment of ecosystem impacts. This report reviews several recent studies of the impacts of climate change on biodiversity. We also review recent quantitative estimates of the rate of species extinctions, the impact of climate change on biodiversity, and the value of biodiversity loss. Based on these estimates, we re-calibrate the biodiversity loss function in the FUND integrated assessment model, and we develop a new global biodiversity nonuse value function. These could serve as replacements for the functions currently used in FUND, or as a preliminary ecosystem damage function in a new integrated assessment model. We also highlight areas where further research is needed for developing more comprehensive and reliable forecasts of ecosystem damages as a result of climate change.

description: Many believe that environmental regulation must reduce employment, since regulations are expected to increase production costs, raising prices and reducing demand for output. A careful microeconomic analysis shows that this not guaranteed. Even if environmental regulation reduces output in the regulated industry, abating pollution could require additional labor (e.g. to monitor the abatement capital and meet EPA reporting requirements). Pollution abatement technologies could also be labor enhancing. In this paper we analyze how a particular EPA regulation, the “Cluster Rule” (CR) imposed on the pulp and paper industry in 2001, affected employment in that sector. Using establishment level data from the Census of Manufacturers and Annual Survey of Manufacturers at the U.S. Census Bureau from 1992-2007 we find evidence of small employment declines (on the order of 3%-7%), sometimes statistically significant, at a subset of the plants covered by the CR.

description: The miniJPAS survey has observed $\sim 1$ deg$^2$ on the AEGIS field with 60 bands (spectral resolution of $R \sim 60$) in order to demonstrate the capabilities of the Javalambre-Physics of the Accelerating Universe Astrophysical Survey (J-PAS) that will map $\sim 8000$ deg$^2$ of the northern sky in the next years. This paper shows the power of J-PAS to detect low mass groups and characterise their galaxy populations up to $z \sim 1$. We use the spectral energy distribution fitting code BaySeAGal to derive the stellar population properties of the galaxy members in 80 groups at $z \leq 0.8$ previously detected by the AMICO code, as well as for a galaxy field sample retrieved from the whole miniJPAS sample. We identify blue, red, quiescent, and transition galaxy populations through their rest-frame (extinction corrected) colour, stellar mass ($M_\star$) and specific star formation rate. We measure their abundance as a function of $M_\star$ and environment. We find: (i) The fraction of red and quiescent galaxies in groups increases with $M_\star$ and it is always higher in groups than in the field. (ii) The quenched fraction excess (QFE) in groups strongly increases with $M_\star$, (from a few percent to higher than 60% in the mass range $10^{10} - 3 \times 10 ^{11}$ $M_\odot$. (iii) The abundance excess of transition galaxies in groups shows a modest dependence with $M_\star$ (iv) The fading time scale is very short ($<1.5$ Gyr), indicating that the star formation declines very rapidly in groups. (v) The evolution of the galaxy quenching rate in groups shows a modest but significant evolution since $z\sim0.8$, compatible with an evolution with constant $QFE=0.4$, previously measured for satellites in the nearby Universe, and consistent with a scenario where the low-mass star-forming galaxies in clusters at $z= 1-1.4$ are environmentally quenched.

description: This paper develops methods for evaluating distributional impacts of alternative environmental policies across demographic groups. The income inequality literature provides a natural methodological toolbox for comparing distributions of environmental outcomes. We show that the most commonly used inequality indexes, such as the Atkinson index, have theoretical properties that make them inappropriate for analyzing bads, like pollution, as opposed to goods, like income. We develop a transformation of the Atkinson index suitable for analyzing bad outcomes. We also show how the rarely used Kolm-Pollak index is particularly convenient for ranking distributions of both good and bad health and environmental outcomes. We demonstrate these methods in the context of emissions standards affecting indoor air quality.

Vortex dynamics in low- and high-extent polymer drag reduction regimes revealed by vortex tracking and conformation analysis

Year: 2019

description: Turbulent flow profiles are known to change between low- (LDR) and high-extent drag reduction (HDR) regimes. It is however not until recently that the LDR-HDR transition is recognized as a fundamental change between two DR mechanisms. Although the onset of DR, which initiates the LDR stage, is explainable by a general argument of polymers suppressing vortices, the occurrence of HDR where flow statistics are qualitatively different and DR effects are observed across a much broader range of wall regions remains unexplained. Recent development of the vortex axis tracking by iterative propagation algorithm allows the detection and extraction of vortex axis-lines with various orientations and curvatures. This new tool is used in this study to analyze the vortex conformation and dynamics across the LDR-HDR transition. Polymer effects are shown to concentrate on vortices that are partially or completely attached to the wall. At LDR, this effect is an across-the-board weakening of vortices which lowers their intensity without shifting their distribution patterns. At HDR, polymers start to suppress the lift-up of streamwise vortices in the buffer layer and prevent their downstream heads from rising into the log-law layer and forming hairpins and other curved vortices. This interrupts the turbulent momentum transfer between the buffer and log-law layers, which offers a clear pathway for explaining the distinct mean flow profiles at HDR. The study depicts the first clear physical picture regarding the changing vortex dynamics between LDR and HDR, which is based on direct evidence from objective statistical analysis of vortex conformation and distribution.

description: Most of the hydrogen in the intergalactic medium (IGM) was rapidly ionized at high-redshifts. While observations have established that reionization occurred, observational constraints on the emissivity of ionizing photons at high-redshift remains elusive. Here, we present a new analysis of the Low-redshift Lyman Continuum Survey (LzLCS) and archival observations, a combined sample of 89 star-forming galaxies at z~0.3 with Hubble Space Telescope observations of their ionizing continua (or Lyman Continuum, LyC). We find a strong (6$σ$ significant) inverse correlation between the continuum slope at 1550Å (defined as F$_λ\proptoλ^β$) and both the LyC escape fraction (f$_{esc}$) and f$_{esc}$ times the ionizing photon production efficiency ($ξ_{ ion}$). On average, galaxies with redder continuum slopes have smaller f$_{esc}$ than galaxies with bluer slopes due to higher dust attenuation. More than 5% (20%) of the LyC emission escapes galaxies with $β$<-2.1 (-2.6). We find strong correlations between $β$ and the gas-phase ionization ([OIII]/[OII] flux ratio; at 7.5$σ$ significance), galaxy stellar mass (at 5.9$σ$), the gas-phase metallicity (at 4.6$σ$), and the observed FUV absolute magnitude (M$_{UV}$ at 3.4$σ$). Using previous observations of $β$ at high-redshift, we estimate the evolution of f$_{esc}$ with both $z$ and M$_{UV}$. The LzLCS suggest that fainter and lower mass galaxies dominate the ionizing photon budget at higher redshift, possibly due to their rapidly evolving metal and dust content. Finally, we use our correlation between $β$ and f$_{ esc}\timesξ_{ion}$ to predict the ionizing emissivity of galaxies during the epoch of reionization. Our estimated emissivities match IGM observations, and suggest that star-forming galaxies emit sufficient LyC photons into the IGM to exceed recombinations near redshifts of 7-8.

description: We carried out wind tunnel experiments on parabolic flights with 100 $μ$m Mojave Mars simulant sand. The experiments result in shear stress thresholds and erosion rates for varying g-levels at 600 Pa pressure. Our data confirm former results on JSC Mars 1A simulant where the threshold shear stress is lower under Martian gravity than extrapolated from earlier ground-based studies which fits observations of Martian sand activity. The data are consistent with a model by Shao and Lu (2000) and can also be applied to other small terrestrial (exo)-planets with low pressure atmospheres.

description: For more than 40 years, IRRI has been both a major player and a platform for leveraging partnerships. One partnership established in 1985 with the Indian Agricultural Research Institute (ICAR) and the Wageningen University and Research Centre (WUR) were able to forge the Systems Analysis for Rice Production (SARP) project to develop and implement systems approaches in rice research. This effort led to greater understanding of weather, crop, soil, and pest interactions in rice and applications of rice models in estimating potential yields, yield gaps, optimal strategies for water and nitrogen management and agroecological zoning. It also resulted in collaboration among scientists of different disciplines using the systems approach as a common way of thinking. Building on the experiences with the systems research in SARP, IRRI, ICAR, and WUR decided in 1996 to continue their partnership to develop tools for land use analysis and planning. This 167-page joint publication of IRRI, ICAR, and WUR reports on various tools developed in these projects to help stakeholders explore options and opportunities for food production to meet the increasing demand, labor, capital, and other resources required for such production levels and their environmental impact. The illustration of the use of a decision support system for Haryan amply demonstrates that considerable progress has been made in developing new tools for ecoregional research.

The solutions are constructed in a sub-truncation of $D=5$, $SO(6)$ maximal gauged supergravity and they all lie within the anti-twist class. We show that the central charge computed from the gravity solutions agrees with an anomaly polynomial calculation associated with compactifying the $\mathcal{N}=1$, $d=4$ Leigh-Strassler SCFT on a spindle.

description: We calculate the density of states in the half-filled Hubbard model on a Bethe lattice with infinite connectivity. Based on our analytical results to second order in $t/U$, we propose a new `Fixed-Energy Exact Diagonalization' scheme for the numerical study of the Dynamical Mean-Field Theory. Corroborated by results from the Random Dispersion Approximation, we find that the gap opens at $U_{\rm c}=4.43 \pm 0.05$. Moreover, the density of states near the gap increases algebraically as a function of frequency with an exponent $α=1/2$ in the insulating phase. We critically examine other analytical and numerical approaches and specify their merits and limitations when applied to the Mott--Hubbard insulator.

After deriving general relations from spectral representations we study correlation functions of Weyl fermions for any value of the index, stressing the related conditions for basis transformations and getting the precise behaviors under gauge and CP transformations. Using the detailed structure of the chiral projections we also obtain a form of the correlation functions with a determinant in the general case.

description: We study the tachyon condensation on the D-brane--antiD-brane system from the supergravity point of view. The non-supersymmetric supergravity solutions with symmetry ISO($p,1$) $\times$ SO($9-p$) are known to be characterized by three parameters. By interpreting this solution as coincident $N$ D$p$-branes and ${\bar N}$ ${\bar {\rm D}}p$-branes we give, for the first time, an explicit representation of the three parameters of supergravity solutions in terms of $N, \bar N$ and the tachyon vev. We demonstrate that the solution and the corresponding ADM mass capture all the required properties and give a correct description of the tachyon condensation advocated by Sen on the D-brane--antiD-brane system.

description: orbitize! is an open-source, object-oriented software package for fitting the orbits of directly-imaged objects. It packages the Orbits for the Impatient (OFTI) algorithm and a parallel-tempered Markov Chain Monte Carlo (MCMC) algorithm into a consistent and intuitive Python API. orbitize! makes it easy to run standard astrometric orbit fits; in less than 10 lines of code, users can read in data, perform one fit using OFTI and another using MCMC, and make two publication-ready figures. Extensive pedagogical tutorials, intended to be navigable by both orbit-fitting novices and seasoned experts, are available on our documentation page. We have designed the orbitize! API to be flexible and easy to use/modify for unique cases. orbitize! was designed by members of the exoplanet imaging community to be a central repository for algorithms, techniques, and know-how developed by this community. We intend for it to continue to expand and change as the field progresses and new techniques are developed, and call for community involvement in this process. Complete and up-to-date documentation is available at orbitize.info.

description: A key feature of the crystallization of supercooled water confined in an applied static electric field is that the structural order here is determined not only by usual thermodynamic and kinematic factors (degree of supercooling, difference between chemical potentials for a liquid and a crystal, and viscosity) but also by the strength and direction of the applied electric field, size of a system (size effects), and the geometry of bounding surfaces. In this work, the electrocrystallization of supercooled water confined between ideally flat parallel graphene sheets at a temperature of $T=268$~K has been considered in this work. It has been established that structural order is determined by two characteristic modes. The initial mode correlates with the orientation of dipolar water molecules by the applied electric field. The subsequent mode is characterized by the relaxation of a metastable system to a crystalline phase. The uniform electric field applied perpendicularly to the graphene sheets suppresses structural ordering, whereas the field applied in the lateral direction promotes cubic ice $I_c$.

description: The purpose of seed health testing is to assure the safe movement of seed of different crops, for research or trade. It is premised on the hypothesis that many harmful organisms are carried by and moved together with the seed, and that these organisms have the potential to cause severe damage to crop production and crop seed for international trade once they are introduced. Seed health testing information reveals the organisms carried by the seed and the level of infection, or infestation, that will be introduced to another region or country. The information, although useful, does not indicate the importance of organisms carried by the seed. For most plant diseases, this information is not available. Such information comes from experiments or surveys under field conditions where the seed is grown.

description: Under the socialist system of collectivized agriculture, Vietnam was a nation of chronic food shortages. Now, thanks to the dramatic Doi Moi economic reforms, Vietnam has transformed itself into one of the world's leading exporters of rice, coffee, rubber, tea, and other agricultural products. This remarkable economic success has been concentrated in the lowland "rice bowl" regions, where farmers had the means to take advantage of the new Doi Moi policies. But in the northern mountains, poverty levels remain high and environmental degradation threatens the continued livelihoods of farmers. This volume presents a series of monographic and analytical studies vital to understanding the heterogeneity and potential of the mountains of northern Vietnam. The Mountain Agrarian Systems Program (SAM) used an interdisciplinary approach to analyze the needs and possibilities of farmers in the mountainous province of Bac Kan. The multiple-scale analysis showed that we need to create not only a spirit of "thinking globally and acting locally", but just as importantly, a spirit of "thinking locally and acting globally". The research provides a foundation for development practitioners and policy makers to identify the successes and failures of past policies and projects, and to target the groups that need development assistance the most.

description: Asian rice systems are undergoing various types of change in response to economic factors and technological opportunities in farming. One such change has been a shift from transplanting to direct-seeding methods for rice establishment. While the rising cost of labor has provided economic incentives for direct seeding, the availability of short-duration rice varieties and chemical weed control methods has made such a shift economically profitable. Direct-seeding methods have also played a critical role in the intensification of Asian rice systems. In the future, in addition to the rising cost of labor, rice farmers of Asia will have to deal with an anticipated increasing scarcity of irrigation water as the demand for water from the urban and industrial sectors expands. Direct-seeding methods, especially dry seeding, may help om achieving higher water-use efficiency. IRRI, together with the Rice Research Institute, Thailand, organized an international workshop on Direct Seeding in Asian Rice Systems: Strategic Issues and Opportunities, held on 25-28 January 2000 in Bangkok, Thailand. The objectives of this workshop were to review past patterns of changes in crop establishment and factors explaining such patterns, assess the likely future patterns of change in crop establishment in various ecosystems and regions, and identify strategic research issues for improving rice productivity by manipulating crop establishment methods and related factors.

Elektrochrome (EC), abdunkelbare Glasscheiben für den Wärme- und Blendschutz in Gebäuden, oft als Smart Windows bezeichnet, sind im Handel erhältlich, ebenso wie selbst abdunkelnde Rückspiegel oder Fenster in Flugzeugkabinen. Kennzeichnend sind der nach wie vor hohe Preis und Glas als Trägermaterial der Systeme. Anwendungen auf Kunststoffbasis wie Visiere, Skibrillen und Autoscheiben, die ein geringes Gewicht, eine dreidimensionale Geometrie und eine Fertigung mit hohem Durchsatz erfordern, sind bislang nicht auf dem Markt. Um derartige EC Bauteile (ECDs) herzustellen, könnte eine flexible EC Folie im Spritzgießverfahren mit Kunststoffschmelze hinterspritzt werden und in einem einzigen automatisierten Schritt mit geringer Verarbeitungszeit zu kompakten 3D-Geometrien weiterverarbeitet werden.

description: This book includes papers tied to a collaborative project to undertake policy analysis and projection studies on supply, demand, and trade of rice in some of the major rice-producing countries. The papers were presented at a workshop on Medium- and Long-Term Prospects of Rice Supply and Demand in the 21st Century held at IRRI headquarters on 3-4 December 2001. Medium- and long-term projections of rice supply, demand, and prices are key information needed to guide national policy decisions and investment plans. In close collaboration with researchers and scientists from the NARES, IRRI, and IFPRI embarked on the collaborative research project to make an in-depth analysis of the changing structure and dynamics of rice supply and demand and to institutionalize the research and policy analysis capacity and projection work as a core research activity in selected NARES. With financial support from the Japanese government and from core funds of IRRI and IFPRI, the project started with the following countries selected to participate: Thailand, Vietnam, Indonesia, Philippines, Malaysia, Myanmar, Japan, South Korea, Taiwan (China), Bangladesh, India, Nepal, and Pakistan.

description: This paper introduces a new synthesis-based defense algorithm for counteracting with a varieties of adversarial attacks developed for challenging the performance of the cutting-edge speech-to-text transcription systems. Our algorithm implements a Sobolev-based GAN and proposes a novel regularizer for effectively controlling over the functionality of the entire generative model, particularly the discriminator network during training. Our achieved results upon carrying out numerous experiments on the victim DeepSpeech, Kaldi, and Lingvo speech transcription systems corroborate the remarkable performance of our defense approach against a comprehensive range of targeted and non-targeted adversarial attacks.

description: IRRI, together with Plant Research International of Wageningen University and Research Centre (WUR-PRI; The Netherlands), organized a thematic workshop on water-wise rice production held 8-11 April 2002 at the IRRI, Los Baños, Philippines. The objectives were to present and discuss the development, dissemination, and adoption of water-saving technologies at spatial scales ranging from the field to the irrigation system. The workshop brought together scientists and irrigation system managers from several consortia and projects examining water scarcity in rice production—the Water Workgroup of the Irrigated Rice Research Consortium, the Rice-Wheat Consortium, and the projects “Water-Less Rice, Growing More Rice with Less Water, and Ground Cover Rice Production Systems. Participants created the International Platform for Saving Water in Rice (IPSWAR). The platform's purpose is to be a mechanism to increase the efficiency and enhance the coherence of research on water savings in rice-based cropping systems in Asia. This book contains 28 papers presented at the workshop on topics of intermittent irrigation, System of Rice Intensification (SRI), aerobic rice, rice-wheat, physiology, and breeding, and irrigation systems.

Local and average fields inside surface-disordered waveguides: Resonances in the one-dimensional Anderson localization regime

description: We investigate the one-dimensional propagation of waves in the Anderson localization regime, for a single-mode, surface disordered waveguide. We make use of both an analytical formulation and rigorous numerical simulation calculations. The occurrence of anomalously large transmission coefficients for given realizations and/or frequencies is studied, revealing huge field intensity concentration inside the disordered waveguide. The analytically predicted s-like dependence of the average intensity, being in good agreement with the numerical results for moderately long systems, fails to explain the intensity distribution observed deep in the localized regime. The average contribution to the field intensity from the resonances that are above a threshold transmission coefficient $T_{c}$ is a broad distribution with a large maximum at/near mid-waveguide, depending universally (for given $T_{c}$) on the ratio of the length of the disorder segment to the localization length, $L/ξ$. The same universality is observed in the spatial distribution of the intensity inside typical (non-resonant with respect to the transmission coefficient) realizations, presenting a s-like shape similar to that of the total average intensity for $T_{c}$ close to 1, which decays faster the lower is $T_{c}$. Evidence is given of the self-averaging nature of the random quantity $\log[I(x)]/x\simeq -1/ξ$. Higher-order moments of the intensity are also shown.
