description: Cette recherche analyse l’impact de la hausse des prix des produits alimentaires (2008-2009) et des mesures de réformes mises en oeuvre par le Togo, sur la pauvreté, la vulnérabilité, les inégalités et les enfants. Grâce à un modèle d’équilibre général partiel et des données de panel, nous montrons que la hausse des prix a des conséquences sur le bien-être des enfants, et des effets négatifs sur les consommateurs nets, tandis que les agriculteurs, producteurs nets voient leur niveau de vie s’améliorer. Cette recherche montre également que les politiques de réponse du gouvernement, en particulier celles relatives à la subvention des intrants agricoles, ont eu un impact positif sur la réduction de la pauvreté. Enfin, nous montrons que des programmes ciblés de filets sociaux auraient des effets plus importants sur la pauvreté et le bien-être des enfants que les mesures régressives et plus couteuses de subvention aux produits pétroliers mis en oeuvres par le Gouvernement....This research analyzes the impact of the rising food prices of 2008-2009 and the policy reforms implemented by Togo, on poverty, vulnerability, inequality and children. Using a partial equilibrium model and panel data, we show that the rising food prices have affected the wellbeing of children and have had negative effects on net consumers, when farmers, who are net producers, improved their welfare. This research also shows that the policies reforms implemented by of the government, especially the agricultural inputs subsidies, have had a positive impact on poverty reduction. Finally, we show that targeted social safety nets programs can have a greater impact on poverty and children’s well-being than the costly regressive oil subsidies implemented by the Government.
Orbifolds from Modular Orbits

description: Given a two-dimensional conformal field theory with a global symmetry, we propose a method to implement an orbifold construction by taking orbits of the modular group. For the case of cyclic symmetries we find that this approach always seems to be consistent, even in asymmetric orbifold cases where the usual construction does not yield a modular invariant theory; our approach keeps modular invariance manifest but may give a result that is equivalent to the original theory. For the case that the symmetry is a subgroup of a continuous flavor symmetry, we can give explicit constructions of the spectrum, with twisted sectors corresponding to a non-standard group projection on an enlarged twisted sector Hilbert space.

description: Abreu-Sena-Dias have constructed two distinct families of scalar-flat Kähler non-compact toric metrics using Donaldson's rephrasing of Joyce's construction in action-angle coordinates. In this paper and using the same set-up, we show that these are the only J-complete scalar-flat Kähler metrics on any given strictly unbounded toric surface. We also show that the asymptotic behaviour of such a metric determines it uniquely.

description: At present, the National Oceanic and Atmospheric Administration is developing new technologies that could offer explicit estimates of the probability that a thunderstorm could produce a tornado up to an hour ahead of the event. Such technologies could radically alter how risk spaces are represented and understood by those who must decide whether or not to take protective action. In addition, there are relatively few studies that examine mapped representations of uncertainty in weather information or the influence of this uncertainty information in weather hazard decision making. To address these gaps, this study presents research subjects with a variety of representations of uncertainty based on the precepts of cartography and information visualization. We propose and test for the existence of three geospatial framing effects that potentially influence subjective estimates of risk: distance from a hazard, warning boundary inclusion or exclusion, and symbolic color coding of uncertainty information. Using a series of computer-aided geographic experiments with a large sample (N = 5,564) of the U.S. population, we find evidence for the existence of each of the three proposed geospatial framing effects. Two of these framings are controlled by the mapmaker—in this case, the weather forecaster—and thus should be considered during the development stages of new products. We discuss the practical implications of the experimental study for current and future tornado warning practices. Key Words: cartography, risk, tornado, uncertainty, visualization.

description: Small farmers are one of the more disadvantaged and vulnerable groups in Nigeria. Studies shown that majority of people living in absolute poverty can be found on small farms with half in this group undernourished and three-quarters of small farmer’s children malnourished. Small farms still dominate agricultural practices in terms of numbers of producers of agricultural commodities. It has been observed that, 74.5% Nigerians population is rural and derived their livelihood from small farms. The question is that these small farms are they going to be a prospering farms or vice-versa? This is the rationale behind this study. Specifically the study looks into heterogeneity in circumstances and diversity in rural livelihoods, the growth of small farms, poverty levels and institutional development facilities available for them was all explore. The index of heterogeneity at 29.1 indicated growth of small farms and about 42% of the respondents were categorized as very poor. The study identified that smallness of farms is not correlated to poverty but the traditionally tried and sometimes fool-proof farming systems. Size of the farms is not the problem, but the operationalization. Evidence from China and India revealed that smallholders are better off in times of productivity. These countries are better in terms of fertilizer consumption, tractor per 100 sq. Km of arable land use and agriculture value added per worker. Conversely, small holder and traditional farmers in Nigeria still use rudimentary production techniques, limited use of improved planting materials and fertilizer consumption, thus suggesting for commercialization of small farms.

A cet effet et au regard des données disponibles (EMICoV 2010), quatre principales dimensions d’autonomisation ont été retenues, à savoir : (i) alphabétisme et niveau d’instruction, (ii) responsabilités sociales et conditions de vie, (iii) participation et droits politiques et (iv) participation et droits culturels. Les résultats obtenus suggèrent globalement un impact positif et significatif du microcrédit sur l’autonomisation des femmes au Bénin, en particulier les pauvres. Cet impact global est l’expression de l’effet significatif du microcrédit sur les dimensions « responsabilités sociales et condition des vie » et « participation et droits culturels » de l’autonomisation. Ainsi, en permettant aux femmes d’être économiquement actives, le microcrédit leur permet d’avoir des possibilités de s’informer et de constituer notamment des actifs physiques qui leur permet d’acquérir plus d’influence dans la communauté.

description: Massive protostars generate strong radiation feedback, which may help set the mass they achieve by the end of the accretion process. Studying such feedback is therefore crucial for understanding the formation of massive stars. We report the discovery of a photoionized bipolar outflow towards the massive protostar G45.47+0.05 using high-resolution observations at 1.3 mm with the Atacama Large Millimeter/Submillimeter Array (ALMA) and at 7 mm with the Karl G. Jansky Very Large Array (VLA). By modeling the free-free continuum, the ionized outflow is found to be a photoevaporation flow with an electron temperature of 10,000 K and an electron number density of ~1.5x10^7 cm^-3 at the center, launched from a disk of radius of 110 au. H30alpha hydrogen recombination line emission shows strong maser amplification, with G45 being one of very few sources to show such millimeter recombination line masers. The mass of the driving source is estimated to be 30-50 Msun based on the derived ionizing photon rate, or 30-40 Msun based on the H30alpha kinematics. The kinematics of the photoevaporated material is dominated by rotation close to the disk plane, while accelerated to outflowing motion above the disk plane. The mass loss rate of the photoevaporation outflow is estimated to be ~(2-3.5)x10^-5 Msun/yr. We also found hints of a possible jet embedded inside the wide-angle ionized outflow with non-thermal emissions. The possible co-existence of a jet and a massive photoevaporation outflow suggests that, in spite of the strong photoionization feedback, accretion is still on-going.

description: Bound states in the continuum (BICs) represent localized modes with energies embedded in the continuous spectrum of radiating waves. BICs were discovered initially as a mathematical curiosity in quantum mechanics, and more recently were employed in photonics. Pure mathematical bound states have infinitely-large quality factors (Q factors) and zero resonant linewidth. In optics, BICs are physically limited by a finite size, material absorption, structural disorder, and surface scattering, and they manifest themselves as the resonant states with large Q factors, also known as supercavity modes or quasi-BICs. Optical BIC resonances have been demonstrated only in extended 2D and 1D systems and have been employed for distinct applications including lasing and sensing. Optical quasi-BIC modes in individual nanoresonators have been discovered recently but they were never observed in experiment. Here, we demonstrate experimentally an isolated subwavelength nanoresonator hosting a quasi-BIC resonance. We fabricate the resonator from AlGaAs material on an engineered substrate, and couple to the quasi-BIC mode using structured light. We employ the resonator as a nonlinear nanoantenna and demonstrate record-high efficiency of second-harmonic generation. Our study brings a novel platform to resonant subwavelength photonics.

Eliminating Tame Ramification: generalizations of Abhyankar's Lemma

description: A basic version of Abhyankar's Lemma states that for two finite extensions $L$ and $F$ of a local field $K$, if $L|K$ is tamely ramified and if the ramification index of $L|K$ divides the ramification index of $F|K$, then the compositum $L.F$ is an unramified extension of $F$. In this paper, we generalize the result to valued fields with value groups of rational rank 1, and show that the latter condition is necessary. Replacing the condition on the ramification indices by the condition that the value group of $L$ be contained in that of $F$, we generalize the result further in order to give a necessary and sufficient condition for the elimination of tame ramification of an arbitrary extension $F|K$ by a suitable algebraic extension of the base field $K$. In addition, we derive more precise ramification theoretical statements and give several examples.

A new characterization protocol allowed the reliable and quantitative assessment of the friction coefficient and adhesion forces at the sub-micrometer scale even for highly corrugated industrial samples. We have studied and compared PTFE coatings charged with different additives in dry and humid environment. The influence of additives and humidity on the friction coefficient and on adhesion forces has been investigated using standard silicon nitride tips as sliders in the low-load regime.

description: This study assessed the determinants of intensity of improved rice varieties adoption using the Tobit model and also employed. The Heckman Two-stage model was used to identify the determinants of market participation and its potential impact on farming households’ welfare in three states selected from the three notable rice producing ecologies in Nigeria. A cross-sectional data of 600 rice farmers from the three states were used in the analysis. The Tobit model revealed that the gender of household head, wealth status, distance to sources of seed, household size, membership of any organisation, and educational background positively and significantly influence the intensity of improved rice varieties adoption. Gender of household head, contact with extension agents, educational background, area cultivated to improved rice varieties, and access to seed were positively and statistically significant in determining market participation. Also, the estimated ordinary least squares (OLS) part or the second step of the Heckman model revealed that how peanut acreage, number of bicycles owned, and the dependency ratio could influence the income from farming as a result of improved variety adoption. Therefore, it is recommended that formation of associations among the rural farmers should be encouraged. Access to seed and information about the improved rice varieties are also essential to increase the intensity of its adoption. Programmes that would improve contact with extension agents, educational background and the proportion of area cultivated to improved rice varieties should be promoted in order to increase market participation and generate improvement in rural households’ welfare.
China Embraces Capitalism and the Prospect of Bankruptcy of State-Owned and Private Companies: Can Provisions for Individual Bankruptcy Be Far Behind?

description: As part of its economic transformation, China has adopted several of the core elements of capitalism, and in the process, has recognized the possibility of bankruptcy for both state-owned-enterprises and private companies. Part I of this paper outlines the main characteristics of the Chinese economy, especially focusing on export and import activities. Part II of the paper outlines in detail the procedures identified as part of the Chinese bankruptcy regulatory environment in order to understand the role that bankruptcy plays in the capitalist model in assuring that decision-making will be conducted on the basis of financial data and will not based on political considerations. At the same time, however, the paper underscores that the prospect of bankruptcy must also be viewed from the prism of internal Chinese politics and traditions relating to socialism. The Chinese government must take into account the prospect of social unrest that the possible bankruptcy of an enterprise would have on Chinese workers, perhaps further weakening the role of the Communist Party in Chinese society. Information is provided regarding bankruptcies that have taken place under the new law. Finally, the paper discusses the possibility of creating a system of bankruptcy for individuals in China which was not a part of the original legislative scheme.

description: We study the interplay between several properties determined from Optical and a combination of Optical/Radio measurements, such as the effective Oxygen yield (y_eff), the star formation efficiency, gas metallicity, depletion time, gas fraction, and baryonic mass(M_bar), among others. We use spectroscopic data from the SDSS survey, and HI information from the ALFALFA survey to build a statistically significant sample of more than 5,000 galaxies. Furthermore, we complement our analysis with data from the GASS and COLD GASS surveys, and with a sample of star-forming galaxies from the Virgo cluster. Additionally, we have compared our results with predictions from the EAGLE simulations, finding a very good agreement when using the high-resolution run. We explore in detail the M_bar-y_eff relation, finding a bimodal trend that can be separated when the stellar age of galaxies is considered. On one hand, y_eff increases with M_bar for young galaxies(log(t_r) < 9.2 yr), while y_eff shows an anti-correlation with M_bar for older galaxies (log(t_r) > 9.4 yr). While a correlation between M_bar and y_eff has been observed and studied before, mainly for samples of dwarfs and irregular galaxies, their anti-correlated counterpart for massive galaxies has not been previously reported. The EAGLE simulations indicate that AGN feedback must have played an important role in their history by quenching their star formation rate, whereas low mass galaxies would have been affected by a combination of outflows and infall of gas.

description: Irrotational dust solutions of Einstein's equations are suitable models to describe the general-relativistic aspects of the gravitational instability mechanism for the formation of cosmic structures. In this paper we study their state space by considering the local initial-value problem formulated in the covariant fluid approach. We consider a wide range of models, from homogeneous and isotropic to highly inhomogeneous irrotational dust models, showing how they constitute equilibrium configurations (invariant sets) of the dynamics. Moreover, we give the characterization of such configurations, which provides an initial-data characterization of the models under consideration.

description: We use a large unique household panel data set spanning 16 years to estimate the impacts of three major Chinese forest conservation and reforestation programs on household incomes. The programs are the most significant of China’s Key Priority Forestry Programs, namely the Sloping Land Conversion Program (the SLCP), the Natural Forest Protection Program (the NFPP), and the Desertification Combating Program around Beijing and Tianjin (the DCBT). Cluster effects with county and environment factors have been estimated by using year dummy variables. Fixed model with cluster effects has been used. In addition to estimating the total impacts of the programs, individually and in combination, we disaggregate the effects by income source, stage of policy implementation, and duration of participation. We find minimal effects on total incomes from the programs overall, which are quiet different with other research empirical results, .but the more detailed results show that the initial stages of the programs, and the early years of participation had negative or neutral effects on land-based incomes, while in more recent years, impacts have improved, and in some cases become positive.

description: The abatement of non-CO2 greenhouse gases (OGHG) has proved to be of paramount importance for reaching global mitigation targets. The modeling of their abatement is normally carried out referring to marginal abatement cost (MAC) curves, which by now represent a standard approach for such an analysis. As no evolution scenarios are available to describe future mitigation opportunities for OGHGs, exogenous technical progress factors (TP) are normally imposed, producing progressive MAC dilatation over time. The main aim of this work is to perform a sensitivity analysis evaluating climate and economic effects of imposing various TPs under different policy scenarios: the analysis shows that TP variation has a considerable impact on the climatic and economic results.

description: EUSO-SPB1 was a balloon-borne pathfinder mission of the JEM-EUSO (Joint Experiment Missions for the Extreme Universe Space Observatory) program. A 12-day long flight started from New Zealand on April 25th, 2017 on-board the NASA's Super Pressure Balloon. With capability of detecting EeV energy air showers, the data acquisition was performed using a 1 m^2 two-Fresnel-lens UV-sensitive telescope with fast readout electronics in the air shower detection mode over ~30 hours at ~16--30 km above South Pacific. Using a variety of approaches, we searched for air shower events. Up to now, no air shower events have been identified. The effective exposure, regarding the role of the clouds in particular, was estimated based on the air shower and detector simulations together with a numerical weather forecast model. Compared with the case assuming the fully clear atmosphere conditions, more than ~60% of showers are detectable regardless the presence of the clouds. The studies in the present work will be applied in the follow-up pathfinders and in the future full-scale missions in the JEM-EUSO program.

title: Plasma currents and inverse bremsstrahlung absorption under strong dc/ac electric fields

Publisher: name: IOP Publishing
Year: 2024

description: Plasma current induced by a strong dc electric field is studied by Fokker-Planck (FP) simulation. Based upon this, a hydrodynamic-like equation, similar to Spitzer's but without the weak-field limit, is given for calculating the current. This equation is suitable for application in hybrid-PIC simulations relevant to the fast ignition (FI) scheme. Furthermore inverse bremsstrahlung (IB) absorption is studied in a wide laser intensity range. In particular, we introduce an IB operator which is similar to Langdon's, but without the low laser intensity limit. This operator enables one to treat IB absorption properly in the inertial confinement fusion (ICF) schemes with the NIF/LMJ-scale laser intensity beyond 10¹⁵ W/cm².

description: We report on the recent results of the hypercentral constituent quark model. The model contains a spin independent three-quark interaction which is inspired by QCD lattice calculations and reproduces the average energy values of the SU(6) multiplets. The splittings are obtained with a residual generalized SU(6)-breaking interaction, including an isospin dependent term. The long standing problem of the Roper resonance is absent and all the 3- and 4-star states are well reproduced. The model has also been used for predictions concerning the electromagnetic transition form factors giving a good description of the medium $Q^2$ -behaviour. In particular the calculated $S_{11} A_{1/2}$ helicity amplitude agrees very well with the recent CLAS data. Finally the ratio of the elastic form factors of the proton, calculated including kinematic relativistic corrections, exhibits a substantial decreasing with $Q^2$ in agreement with the recent TJNAF experiment.

description: Twelve indole diketopiperazine alkaloids (1‒12) including four new ones aspechinulins A‒D (1, 3, 5 and 12) were isolated from the deep-sea-derived fungus Aspergillus sp. FS445. Their structures were elucidated through spectroscopic analysis and the absolute configurations were determined by analyzing the experimental ECD data as well as the quantum chemical calculations. Compounds 1, 3 and 5 represented the first examples of indole diketopiperazine derivatives constructing a C5 unit at 11-NH through an imide linkage. The NO production inhibitory activity of the isolated compounds was evaluated and compounds 2‒5, 7 and 9 exhibited potential inhibitory activities against NO production with the IC50 values in the range of 20 ∼ 90 µM.

description: We study the generation of a stochastic gravitational wave (GW) background produced from a population of core-collapse supernovae, which form black holes in scenarios of structure formation. We obtain, for example, that the formation of a population (Population III) of black holes, in cold dark matter scenarios, could generate a stochastic GW background with a maximum amplitude of $h_{\rm BG} \simeq 10^{-24}$ and corresponding closure energy density of $Ω_{\rm{GW}}\sim 10^{-7}$, in the frequency band $ν_{\rm{obs}} \simeq 30-470 {\rm Hz}$ (assuming a maximum efficiency of generation of GWs, namely, $ε_{\rm GW_{\rm max}} = 7\times 10^{-4}$) for stars forming at redshifts $z\simeq 30-10.$ We show that it will be possible in the future to detect this isotropic GW background by correlating signals of a pair of `advanced' LIGO observatories (LIGO III) at a signal-to-noise ratio of $\simeq 40$. We discuss what astrophysical information could be obtained from a positive (or even a negative) detection of such a GW background generated in scenarios such as those studied here. One of them is the possibility of obtaining the initial and final redshifts of the emission period from the observed spectrum of GWs.

description: $^{63}$Cu NMR measurements are reported for the Cu-rich phase of \ch{Cu_{12+x}Sb4S13} ($x \lesssim 2$) and compared to \ch{Cu12Sb4S13}. We identify the NMR signatures of the phase segregation into Cu-poor ($x \approx 0$) and Cu-rich ($x \lesssim 2$) phases, with the metal-insulator transition observed in \ch{Cu12Sb4S13} suppressed in the Cu-rich phase. Based on NMR $T_1$ and $T_2$ measurements, the results demonstrate Cu-ion hopping below room temperature with an activation energy of $\sim$150 meV for the Cu-rich phase, consistent with superionic behavior. The NMR results also demonstrate the effects of Cu-ion mobility in the \ch{Cu12Sb4S13} phase, but with a larger activation barrier. We identify a small difference in NMR Knight shift for the metallic phase of \ch{Cu12Sb4S13}, compared to the Cu-rich phase, and when compared to DFT calculations the results indicate a mix of hyperfine contributions to the metallic shift.
Mental Accounting: A New Behavioral Explanation of Covered Call Performance

description: The empirical performance of covered call writing is quite puzzling in the traditional finance framework. Covered call writing is typically a risk reducing strategy so its expected return should be less than the expected return on the underlying in an efficient market. However, recent empirical evidence suggests (covering a period from 1988 onwards) that the covered call writing has nearly the same return as the underlying whereas the standard deviation of returns is considerably less. Market professionals consider a call option to be a surrogate for the underlying. Such mental accounting of a call option with the underlying has strong support in laboratory experiments. We show that such mental accounting embodied in the principle, assets with similar payoffs must have the same expected returns, provides a new behavioral explanation for the puzzling empirical performance of covered call writing.
Decoherent histories analysis of the relativistic particle

description: The Klein-Gordon equation is a useful test arena for quantum cosmological models described by the Wheeler-DeWitt equation. We use the decoherent histories approach to quantum theory to obtain the probability that a free relativistic particle crosses a section of spacelike surface. The decoherence functional is constructed using path integral methods with initial states attached using the (positive definite) ``induced'' inner product between solutions to the constraint equation. The notion of crossing a spacelike surface requires some attention, given that the paths in the path integral may cross such a surface many times, but we show that first and last crossings are in essence the only useful possibilities. Different possible results for the probabilities are obtained, depending on how the relativistic particle is quantized (using the Klein-Gordon equation, or its square root, with the associated Newton-Wigner states). In the Klein-Gordon quantization, the decoherence is only approximate, due to the fact that the paths in the path integral may go backwards and forwards in time. We compare with the results obtained using operators which commute with the constraint (the ``evolving constants'' method).

The Financial Market Consequences of Growing Awareness: The Case of Implied Volatiltiy Skew

description: The belief that the essence of the Black Scholes model is correct implies that one is unaware that a delta-hedged portfolio is risky, while believing that the proposition, a delta-hedged portfolio is risk-free, is true. Such partial awareness is equivalent to restricted awareness in which one is unaware of the states in which a delta-hedged portfolio is risky. In the continuous limit, two types of restricted awareness are distinguished. 1) Strongly restricted awareness in which one is unaware of the type of the true stochastic process. 2) Weakly restricted awareness, in which one is aware of the type of the true stochastic process, but is unaware of the true parameter values. We apply the generalized principle of no-arbitrage (analogy making) to derive alternatives to the Black Scholes model in each case. If the Black Scholes model represents strongly restricted awareness, then the alternative formula is a generalization of Merton’s jump diffusion formula. If the Black Scholes formula represents weakly restricted awareness, then the alternative formula, first derived in Siddiqi(2013), is a generalization of the Black Scholes formula. Both alternatives generate implied volatility skew. Hence, the sudden appearance of the skew after the crash of 1987 can be understood as the consequence of growing awareness, as investors realized that a delta-hedged portfolio is risky after suffering huge losses in their portfolio-insurance delta-hedges. The different implications of strongly restricted awareness vs. weakly restricted awareness for option pricing are discussed.
