description: The green economy, including biofuels and biomass production, has received consider-able academic and popular press attention. Yet, documenting and measuring the economic impact of green economy activities remains a challenge, as this ill-defined economic sector’s benefits are often overstated. This article makes two unique contributions to the emerging ac-ademic literature on the green economy. First, it contributes to the applied academic literature on economic impact assessments of the green economy by documenting approaches to meas-ure the economic impact of three alternative biomass uses: electricity generation, wood pellet manufacturing, and biofuels manufacturing. Second, it examines the regulatory influences and market volatility that challenge the long-term viability of each alternative use.

description: We show that the modified Cardy-Verlinde formula without the Casimir effect term is satisfied by asymptotically flat charged black holes in arbitrary dimensions. Thermodynamic quantities of the charged black holes are shown to satisfy the energy-temperature relation of a two-dimensional CFT, which supports the claim in our previous work (Phys. Rev. D61, 044013, hep-th/9910244) that thermodynamics of charged black holes in higher dimensions can be effectively described by two-dimensional theories. We also check the Cardy formula for the two-dimensional black hole compactified from a dilatonic charged black hole in higher dimensions.

description: This study explores the effect of different phases of unconventional shale gas well-pad development on ambient air quality and the relationship between ambient concentrations of air pollutants and operator activity. The U.S. Department of Energy’s National Energy Technology Laboratory operated a mobile air-monitoring laboratory on two shale well pad sites in Pennsylvania and six shale well pad sites in West Virginia. The purpose of this study is to integrate expert knowledge and collected ambient air monitoring data by developing a Bayesian network (BN) model. The monitoring period included well-pad site development; construction, including vertical and horizontal drilling; hydraulic fracturing; flowback; and production. The observed data includes meteorological data with high time resolution and air quality data (volatile organic compounds (VOCs), ozone, methane and carbon isotopes in methane, carbon dioxide (CO2) and carbon isotopes in CO2, coarse and fine particulate matter (PM10 and PM2.5), and organic and elemental carbon). The results provide useful information for evaluating the influence of on- and off-site pollutant sources and determining future research efforts for building the BN model. The overall results of the developed six scenarios show that the prediction power of the proposed model for the vertical drilling phase is 94%. The high concentration of methane increases the probability of fracturing phase as source; the low concentration of PM10 and O3 occurrence increases the same probability to 82%; the low concentration of ethane and CO2 increases the probability to 98%. This study shows how expert Bayesian models can improve our ability to predict future air pollution risk associated with unconventional shale gas development.

description: Several attempts have been made to analyze the financial performance benefits of creating long-term value for business firms through adopting sustainable practices, however empirical evidence has been inconsistent. This study examined corporate financial performance data for a sample of 493 firms in the USA during the period 2000-2014, a much longer time frame than in previous studies (average of 4 years), which allowed examination of continuously versus occasionally participating firms. Quantile Difference-in-Differences model was applied to account for the recessionary economic conditions during 2008-09. A Propensity Score Matching method was used to select comparable firms listed in the Dow Jones Sustainability Index (DJSI). It was shown that Corporate Sustainability (CS) does provide significant financial losses within eight years. Moreover, Information, Services and Retail Trade industries are seemed to ideally managing their investment in CS. Also, the study showed that certain industries that were more efficient and faster in absorbing the benefits of CS. It was found that a period of eight years was insufficient to reap the benefits of CS.

description: Food cooperatives (co-ops) as a key component of the local food network play an increasingly important role in the US food system. Co-ops use various strategies to promote local products, ensure a greater commitment of members, and the rofitability and sustainability of the business. This paper assessed the effectiveness of these strategies as perceived and appreciated by co-ops' members using survey data from a national study on eight large food cooperatives in the U.S. The survey identifies a wide range of attributes related to store and product characteristics, and marketing and management strategies. It asks interviewees to rank their co-op on these attributes on a Likert-scale of 0-4. Using Principal Component Analysis, we aggregate and combine information from the large number of rankings into a six major categories. Next, exploiting the hierarchical structure of the data with members nested within their respective co-ops, we use Hierarchical Linear Modeling methods to identify the factors that determine the perceived performance of co-ops. The results show that in general member has a strong positive perception of the performance of their co-ops in term of quality of the products, quality of the management and the service, and the physical quality of the store. We also find there is a lot heterogeneity among co-ops and member socio-demographic and economic characteristics are strongly correlated with their perception.

description: Chronic pulmonary aspergillosis (CPA) is often poorly responsive to antifungal treatment; secondary infections increase morbidity/mortality, particularly in progressive cases. Interferon gamma (IFNγ) has been implicated in not only Aspergillus control but also bacterial clearance. Clinical notes of patients with CPA treated with IFNγ (2011–2018) were retrospectively hand-searched. In patients treated for >12 months (n=20), the frequency of acute exacerbation reduced from 3.1 to 1.4 episodes/year (p=0.006) in the 12 months after treatment initiation compared with the 12 months before. A significant reduction in the frequency of hospital admissions/year was also observed (0.8 to 0.3, p=0.04). These findings support further prospective studies.

description: We consider, from several complementary perspectives, the physics of confinement and deconfinement in the 2+1 dimensional Georgi-Glashow model. Polyakov's monopole plasma and 't Hooft's vortex condensation are discussed first. We then discuss the physics of confining strings at zero temperature. We review the Hamiltonian variational approach and show how the linear confining potential arises in this framework. The second part of this review is devoted to study of the deconfining phase transition. We show that the mechanism of the transition is the restoration of 't Hooft's magnetic symmetry in the deconfined phase. The heavy charged $W$ bosons play a crucial role in the dynamics of the transition, and we discuss the interplay between the charged $W$ plasma and the binding of monopoles at high temperature. Finally we discuss the phase transition from the point of view of confining strings. We show that from this point of view the transition is not driven by the Hagedorn mechanism (proliferation of arbitrarily long strings), but rather by the "disintegration" of the string due to the proliferation of 0 branes.

Early Enrichment of the Intergalactic Medium and its Feedback on Galaxy Formation

description: Supernova-driven outflows from early galaxies may have had a large impact on the kinetic and chemical structure of the intergalactic medium (IGM). We use three-dimensional Monte Carlo cosmological realizations of a simple linear peaks model to track the time evolution of such metal-enriched outflows and their feedback on galaxy formation. We find that at most 30% of the IGM by volume is enriched to values above 10^-3 solar in models that only include objects that cool by atomic transitions. The majority of enrichment occurs relatively early (5 < z < 12) and resulting in a mass-averaged cosmological metallicity between 10^-3 and 10^-1.5 solar. The inclusion of Population III objects that cool through H2 line emission has only a minor impact on these results: increasing the mean metallicity and filling factor by at most a factor of 1.4, and moving the dawn of the enrichment epoch to a redshift of approximately 14 at the earliest. Thus enrichment by outflowing galaxies is likely to have been incomplete and inhomogeneous, biased to the areas near the starbursting galaxies themselves. Models with a 10% star formation efficiency can satisfactorily reproduce the nearly constant (2 < z < 5, Z approximately 3.5 x 10^-4 solar) metallicity of the low column density Ly-alpha forest derived by Songaila (2001), an effect of the decreasing efficiency of metal loss from larger galaxies. Finally, we show that IGM enrichment is intimately tied to the ram-pressure stripping of baryons from neighboring perturbations. This results in the suppression of at least 20% of the dwarf galaxies in the mass range 10^8.5 to 10^9.5 solar, in all models with filling factors greater than 2%, and an overall suppression of approximately 50% of dwarf galaxies in the most observationally-favored model.

description: The critical behavior of a non-local scalar field theory is studied. This theory has a non-local quartic interaction term which involves a real power -βof the Laplacian. The parameter βcan be tuned so as to make that interaction marginal for any dimension. The lowest order Feynman diagrams corresponding to coupling constant renormalization, mass renormalization, and field renormalization are computed. In all cases a non-trivial IR fixed point is obtained. Remarkably, for dimensions different from 4, field renormalization is required at the one-loop level. For d=4, the theory reduces to the usual local ϕ^{4} field theory and field renormalization is required starting at the the two-loop level. The critical exponents νand ηare computed for dimensions 2,3,4 and 5. For dimensions greater than four, the critical exponent ηturns out to be negative for ε>0, which indicates a violation of the unitarity bounds.

COMMENT
Doubtfully present in Algeria. Ros et al. (2007a) included it in the Algerian list as a “Report without precise collection data or locality”, based erroneously on Jelenc (1955a), who included its synonym A. crispulus (Mont.) Douin as sine loco for northern Africa based on Trabut information, but not for Algeria. It has often been confused with A. punctatus in old literature (Söderström et al. 2002), which led Ros et al. (2007a) to think that most of the Mediterranean reports should belong to A. punctatus.

description: Despite sustained efforts made by developing countries and the international community hunger and malnutrition continue to be major challenges faced by millions of individuals and communities. While domestic policies and investments in food insecure countries will be essential in addressing the needs and gaps that exist, policies from outside their borders also play an important role. Given the importance of OECD countries in world trade, this study seeks to understand the spillover effect of their domestic non-aid policies on the food security in developing countries with a focus on Tanzania. We consider various OECD countries policies such as domestic supports to agriculture, non-tariffs measures and foreign direct investment policies. Using a set of qualitative and quantitative methods and sectoral studies we found that, historically, OECD countries policies have had sizable negative effects on Tanzanian agriculture and food security. The direction and magnitude of the effects varies across sectors and households. We also found that in recent years, the OECD has been actively engaged in efforts to promote the coherence of its policies to ensure that they are mutually supportive of development goals in the developing world.

description: Despite the human nutritional benefits of seafood such as shrimp, per capita consumption has been declining since 2004. A few studies have been conducted, but the literature is still limited. Indeed, studies that have analyzed the market demand for seafood and shrimp in the United States don’t furnish empirical estimates of the consumer behavior of this market. This void in literature is evident, as recent works have either used aggregated data on seafood or disaggregated shrimp data but focusing on shrimp imports. This paper uses the Almost Ideal Demand System (AIDS) to estimate the demand for shrimp in Texas, using AC Nielsen Scanner consumption panel data collected from four metropolitan areas: Dallas, Houston, San Antonio, and West Texas. The data ranges from 2006 to 2010. The demand for shrimp is estimated in a system of demand equations for ten fish species. The availability of data on these various kinds of fish enables the assumption of separability of seafood from other food products. The results suggest that all the fish species considered are normal goods and that shrimp demand is price sensitive with an uncompensated own price elasticity of -1.53 and an income elasticity of 0.98. This is partly attributed to the fact that consumers view other fish types as substitutes for shrimp.

description: Chaperone-assisted translocation through a nanopore embedded in membrane holds a prominent role in the transport of biopolymers. Inspired by classical Brownian ratchet, we develop a theoretical framework characterizing such translocation process through a master equation approach. In this framework, the polymer chain, provided with reversible binding of chaperones, undergoes forward/backward diffusion, which is rectified by chaperones. We drop the assumption of timescale separation and keep the length of a polymer chain finite, both of which happen to be the key points in most of the previous studies. Our framework makes it accessible to derive analytical expressions for mean translocation velocity and effective diffusion constant in stationary state, which is the basis of a comprehensive understanding towards the dynamics of such process. Generally, the translocation of polymer chain across membrane consists of three subprocesses: initiation, termination, and translocation of the main body part of a polymer chain, where the translocation of the main body part depends on the binding/unbinding kinetics of chaperones. That is the main concern of this study. Our results show that the increase of forward/backward diffusion rate of a polymer chain and the binding/unbinding ratio of chaperones both raise the mean translocation velocity of a polymer chain, and roughly speaking, the dependence of effective diffusion constant on these two factors achieves similar behavior.

description: There are two major players in the transportation system: users and decision makers. Traditionally, public agencies (transportation agencies at the federal, state, county, and local level) held most of the decision-making powers related to transportation. The decision makers referred to in this study include county engineers, county road supervisors, and county commissioners. These decisions pertain to the physical infrastructure and operating characteristics of roadways. Infrastructure issues include financing and programming of building, improving, and maintaining highway transportation structures. Operational issues include regulations, enforcement, and taxing of users. A multitude of federal and state laws were established to assure efficient and safe use of the nation's transportation infrastructure. Road users, on the other hand, include motorists and motor carriers who utilize the highway transportation system. These users finance some costs of the transportation system by paying taxes and user fees. Road users typically expect adequate road services to be provided by governmental agencies. Users of transportation services participate in directing some road decisions through public input mechanisms and input to elected officials. However, in many cases, there still will be differences between perceptions of providers and users. To fill this gap, new federal policy specifically had mandated transportation agencies to adopt active and effective public participation plans. The transportation plans developed according to the 1991 Inter-modal Surface Transportation Efficiency Act (ISTEA) requirements and continued in the Transportation Efficiency Act of the 21st Century (TEA-21) consider input from extensive public involvement process. However, these efforts still are rudimentary in many states. In addition, user groups targeted for participation usually are located in urban centers where most of the population and economic activities are located. Even in these areas, citizen participation is limited. This paper summarizes the results of a study on direct assessment of rural user needs in three states including Montana, North Dakota, and South Dakota. The objective of the study was to assess rural road users and providers perception of rural road needs. Different rural road user groups were identified to obtain a representative sample of perceptions. User groups targeted in the study included commuters, delivery services, mail carriers, school bus drivers, and farmers. An attitudinal survey was developed and administered to these groups.

description: The quark-monopole potential is computed at finite temperature in the context of $AdS/CFT$ correspondence. It is found that the potential is invariant under $g \to 1/g$ and $U_T \to U_T / g$. As in the quark-quark case there exists a maximum separation between quark and monopole, and $L$-dependence of the potential exhibits a bifurcation behavior. We find a functional relation $dE_{QM}^{Reg} / dL = [(1/E_{(1,0)}^{Reg}(U_0))^2 + (1/E_{(0,1)}^{Reg}(U_0))^2]^{-1/2}$ which is responsible for the bifurcation. The remarkable property of this relation is that it makes a relation between physical quantities defined at the $AdS$ boundary through a quantity defined at the bulk. The physical implication of this relation for the existence of the extra dimension is speculated.

description: Phenyl-perfluorophenyl polar-π interactions have been revisited for the design and fabrication of functional supramolecular systems. The relatively weak associative interactions (ΔG ≈ -1.0 kcal/mol) have limited their use in aqueous self-assembly to date. Herein, we propose a strategy to strengthen phenyl-perfluorophenyl polar-π interactions by encapsulation within a synthetic host, thus increasing the binding affinity to ΔG= -15.5 kcal/mol upon formation of heteroternary complexes through social self-sorting. These heteroternary complexes were used as dynamic, yet strong, cross-linkers in the fabrication of supramolecular gels, which exhibited excellent viscoelasticity, stretchability, self-recovery, self-healing, and energy dissipation. This work unveils a general approach to exploit host-enhanced polar-π interactions in the design of robust aqueous supramolecular systems.

description: The sensitivity of stellar spectra to alpha/Fe abundance changes is investigated with the aim to be detected photometricly and employed for scientific goals of the GAIA mission. A grid of plane parallel, line blanketed, flux constant, LTE model atmospheres with different [alpha/Fe] ratios was calculated. As a first step, the modelled stellar energy fluxes for solar-type stars and giants were computed and intercompared. The spectral sensitivity talpha/Fe abundance changes is noticeable and has to be taken into account when selecting photometric filters for GAIA. The Ca II H and K lines and Mg I b triplet are the most sensitive direct indicators of alpha/Fe abundance changes.

Complete multipolar description of reflection and transmission across a metasurface for perfect absorption of light

description: Relating the electromagnetic scattering and absorption properties of an individual particle to the reflection and transmission coefficients of a two-dimensional material composed of these particles is a crucial concept that has driven both fundamental and applied physics. It is at the heart of both the characterization of material properties as well as the phase and amplitude engineering of a wave. Here we propose a multipolar description of the reflection and transmission coefficients across a monolayer of particles using a vector spherical harmonic decomposition. This enables us to provide a generalized condition for perfect absorption which occurs when both the so-called \textit{generalized Kerker condition} is reached and when the superposition of odd and even multipoles reaches a critical value. Using these conditions, we are able to propose two very different designs of two-dimensional materials that perfectly absorb a plane electromagnetic wave under normal incidence. One is an infinite array of silica microspheres that operates at mid-infrared frequencies, while the other is an infinite array of germanium nano-clusters that operates at visible frequencies. Both systems operate in a deeply multipolar regime. Our findings are important to the metamaterials and metasurfaces communities who design materials mainly restricted to the dipolar behavior of individual resonators, as well as the self-assembly and nanochemistry communities who separate the individual particle synthesis from the materials assembly.

description: Fe2As has been studied in situ by synchrotron powder X-ray diffraction (PXRD) over the range of temperatures 25-850 °C and under a neutral atmosphere to understand its thermal behavior, which is potentially important for gold extraction. For the first time, incongruent high-temperature reactions of Fe2As are observed as it breaks down and the existence of a previously undiscovered high-temperature FeAs phase with an NiAs-type structure has been determined experimentally. No evidence has been found for the existence of the high-temperature Fe3As2 phase. Hence, the previously published phase diagram for the Fe-As system has to be modified accordingly.

description: The explicit form of the quantum propagator of a bosonic p-brane, previously obtained by the authors in the quenched-minisuperspace approximation, suggests the possibility of a novel, unified, description of p-branes with different dimensionality. The background metric that emerges in this framework is a quadratic form on a Clifford manifold. Substitution of the Lorentzian metric with the Clifford line element has two far reaching consequences. On the one hand, it changes the very structure of the spacetime fabric since the new metric is built out of a Minimum Length below which it is impossible to resolve the distance between two points; on the other hand, the introduction of the Clifford line element extends the usual relativity of motion to the case of Relative Dimensionalism of all p-branes that make up the spacetime manifold near the Planck scale.

description: The wrinkling transition experimentally identified by Mutz et al. [Phys. Rev. Lett. 67, 923 (1991)] and then thoroughly studied by Chaieb et al. [Phys. Rev. Lett. 96, 078101 (2006)] in partially polymerized lipid membranes is reconsidered. One shows that the features associated with this transition, notably the various scaling behaviors of the height-height correlation functions that have been observed, are qualitatively and quantitatively well described by a recent nonperturbative renormalization group (NPRG) approach to quenched disordered membranes by Coquand et al. [Phys. Rev E 97, 030102 (2018)]. As these behaviors are associated with fixed points of RG transformations they are universal and should also be observed in, e.g., defective graphene and graphene-like materials.

description: For Li-air batteries, dissolved gas can cross over from the air electrode to the Li metal anode and affect the solid-electrolyte interphase (SEI) formation, a phenomenon that has not been fully characterized. In this work, the impact of atmospheric gases on the SEI properties is studied using electrochemical methods and ex situ characterization techniques, including X-ray photoelectron spectroscopy, X-ray diffraction, Fourier transform infrared spectroscopy, and scanning electron microscopy. The presence of O2 significantly improved the lithium cyclability; less lithium is consumed to form the SEI or is lost because of electrical disconnects. However, the SEI resistivity and plating overpotentials increased. Lithium cycled in an "air-like" mixed O2/N2 environment also demonstrated improved cycling efficiency, suggesting that dissolved O2 participates in electrolyte reduction, forming a homogeneous SEI, even at low concentrations. The impact of gas environments on Li metal plating and SEI formation represents an additional parameter in designing future Li-metal batteries.

description: William Ping, the narrator of the novel, Hollow Bamboo, is a typical, privileged millennial. His life revolves around eating at restaurants and then posting online about eating at restaurants. This all changes when a dinner with his Chinese girlfriend’s family forces him to confront both his biracial identity and his ignorance of his own Chinese heritage. Midway through dinner, Will suffers a potentially fatal injury and is visited by a dream-eating spirit named Mo who whisks him into the past to learn about the life of his grandfather, the first William Ping, who immigrated from China to Newfoundland in the 1930’s. Based on a true story, the novel recounts the often brutal struggles, and occasional successes, faced by some of the first Chinese immigrants in Newfoundland. A speculative biography, rehearsing familial anecdotes and personal histories, tempered with the problematic authority of documented facts; this blend of historical material and magical imaginings renders the novel a unique look at the integration and disintegration of Chinese culture in the life of two William Pings.

description: In eukaryotic cells, protein sorting is a highly regulated mechanism important for many physiological events. After synthesis in the endoplasmic reticulum and trafficking to the Golgi apparatus, proteins sort to many different cellular destinations including the endolysosomal system and the extracellular space. Secreted proteins need to be delivered directly to the cell surface. Sorting of secreted proteins from the Golgi apparatus has been a topic of interest for over thirty years, yet there is still no clear understanding of the machinery that forms the post-Golgi carriers. Most evidence points to these post-Golgi carriers being tubular pleomorphic structures that bud from the trans-face of the Golgi. In this review, we present the background studies and highlight the key components of this pathway, we then discuss the machinery implicated in the formation of these carriers, their translocation across the cytosol, and their fusion at the plasma membrane.
