description: The role of infrastructure in economic growth and welfare has been studied extensively across the literature over the past three decades. We use a dynamic CGE model linked to a microsimulation model to estimate the macro-micro impact of public infrastructure investment. Two approaches to public investment are considered in our simulations. In the first, production taxes finance the additional public infrastructure investment and in the second, foreign borrowing provides resources. Our results reveal that public infrastructure investments have the same direction of impact whether funded by taxation or international borrowing, particularly when looking at macroeconomic gains and poverty reduction in the long run. However, in the very short run, tax financing puts a strain on output in the industrial sector and thus reduces economic growth in the short run. The financing from international borrowing has a Dutch disease-like impact in the short run, as indicated by a decline in exports.

description: By means of pump-probe time- and angle-resolved photoelectron spectroscopy, we provide evidence of a sizeable reduction of the Fermi velocity of out-of-equilibrium Dirac bands in the quasi-two-dimensional semimetal BaNiS$_2$. First-principle calculations indicate that this band renormalization is ascribed to a change in non-local electron correlations driven by a photo-induced enhancement of screening properties. This effect is accompanied by a slowing down of the Dirac fermions and by a non-rigid shift of the bands at the center of the Brillouin zone. This result suggests that other similar electronic structure renormalizations may be photoinduced in other materials in presence of strong non-local correlations.

description: Agricultural activities have been and remain key for sustained growth and pro-poor development in Ethiopia. However, the sector under utilizes its irrigation capacities as well as its abundant human resources. This paper aims at measuring the impact of public investment in small-scale irrigation and training for farmers on growth and agriculture-led development, on food security, and on poverty in Ethiopia. It is line with the current five year development strategy of the government and will give insights on the effect of selected targeted indicators. We use a dynamic Computable General Equilibrium (CGE) model to capture the outcomes of public investment shocks. Public investment is modeled in such a way that it increases the supply of skilled agricultural labor and that of irrigated land by transforming unskilled labor and non irrigated land. Two types of technologies are utilized in agriculture to produce the same crop : a more productive technology that is intensive in skilled labor and irrigated land and a less productive technology that is intensive in unskilled labor and non-irrigated land. Households have the ability to increase their endowments in labor and land. Hence, the increase in skilled labor due to public investment in the form of short term training enables households to increase the share of skilled labor they detain while reducing the share of unskilled labor. The same applies for land. Finally, the model has a poverty module using a top-down approach where changes in the CGE model are imported in the household data. The CGE model is a PEP type model and is calibrated to a SAM of Ethiopia for the fiscal year 2005/06. The poverty module uses the 2005 Household Income and Expenditure Survey. This exercise showed that the Ethiopian government policy strategy regarding agriculture sector development has a great potential for reducing poverty and food insecurity. Simulation results show that investing in training and irrigation contributes to the effort towards achieving the MDGs. Exports expand and in particular export of cash crops that generate higher income at household and national levels. The results also show that an agriculture-led development is less likely to occur because of weak forward and backward production linkages between agriculture and manufacturing sectors where a great deal of manufacturing inputs are imported. The increment in public investment has a crowding-out effect that affects the expansion of manufacturing and services sectors which are highly intensive in private capital.

description: e investigate the energy loss of quark and gluon jets in quark-gluon plasma produced in central Au+Au collisions at RHIC energy. We use the physical characteristic of initial and mixed phases, which were found in effective quasiparticle model for SPS and RHIC energy. At investigation of energy loss we take into account also the production of hot glue at first stage. The energy loss in expanding plasma is calculated in dominant first order of radiation intensity with accounting of finite kinematic bounds. We calculate the suppression of $π^0$ - spectra with moderate high $p_{\perp}$, which is caused by energy loss of quark and gluon jets. The comparison with suppression of $π^0$ reported by PHENIX show, that correct quantitative description of suppression we have only in model of phase transition with decrease of thermal gluon mass and effective coupling $G(T)$ in region of phase transition plasma into hadrons (at $T \simeq T_c$). However quasiparticle model with increase of these values at $T \to T_c$ in accordance with perturbative QCD lead to too great energy loss of gluon and quark jets, which disagrees with data on suppression of $π^0$. Thus it is possible with help of hard processes to investigate the structure of phase transition. We show also, that energy losses at SPS energy are too small in order to be observable. This is caused in fact by sufficiently short plasma phase at this energy.

description: A significant gap remains between rural and urban students in the rate of admission to senior high school. One reason for this gap may be high tuition and other school fees at the senior high school level. By reducing student expectations of attending high school, high tuition and school fees can reduce student academic performance in junior high school. In this paper we evaluate the impact of a senior high tuition relief program on the test scores of poor, rural seventh grade students in China. We surveyed three counties in Shaanxi Province and exploit the fact that, while the counties are adjacent to one another and share similar characteristics, only one of the three implemented a tuition relief program. Using several alternative estimation strategies, including difference-in-differences (DD), difference-indifference- in-differences (DDD), propensity score matching (PSM) and difference-indifferences matching (DDM), we find that the tuition program has a statistically significant and positive impact on the math scores of seventh grade students. More importantly, this program is shown to have the largest (and only significant) impact on the poorest students.

description: We show that the bivariant Chern character in entire cyclic cohomology constructed in a previous paper in terms of superconnections and heat kernel regularization, retracts on periodic cocycles under some finite summability conditions. The trick is a bivariant generalization of the Connes-Moscovici method for finitely summable K-cycles. This yields concrete formulas for the Chern character of p-summable quasihomomorphisms and invertible extensions, analogous to those of Nistor. The latter formulation is completely algebraic and based on the universal extensions of Cuntz and Zekri naturally appearing in the description of bivariant K-theory.

description: This work presents a computational method for the design of architected truss lattice materials where each strut can be made of one of a set of available materials. We design the lattices to extremize effective properties. As customary in topology optimization, we design a periodic unit cell of the lattice and obtain the effective properties via numerical homogenization. Each bar is represented as a cylindrical offset surface of a medial axis parameterized by the positions of the endpoints of the medial axis. These parameters are smoothly mapped onto a continuous density field for the primal and sensitivity analysis via the geometry projection method. A size variable per material is ascribed to each bar and penalized as in density-based topology optimization to facilitate the entire removal of bars from the design. During the optimization, we allow bars to be made of a mixture of the available materials. However, to ensure each bar is either exclusively made of one material or removed altogether from the optimal design, we impose optimization constraints that ensure each size variable is 0 or 1, and that at most one material size variable is 1. The proposed material interpolation scheme readily accommodates any number of materials. To obtain lattices with desired material symmetries, we design only a reference region of the unit cell and reflect its geometry projection with respect to the appropriate planes of symmetry. Also, to ensure bars remain whole upon reflection inside the unit cell or with respect to the periodic boundaries, we impose a no-cut constraint on the bars. We demonstrate the efficacy of our method via numerical examples of bulk and shear moduli maximization and Poisson's ratio minimization for two- and three-material lattices with cubic symmetry.

description: We propose a spectral quark model which can be applied to low energy hadronic physics. The approach is based on a generalization of the Lehmann representation of the quark propagator. We work at the one-quark-loop level. Electromagnetic and chiral invariance are ensured with help of the gauge technique which provides particular solutions to the Ward-Takahashi identities. General conditions on the quark spectral function follow from natural physical requirements. In particular, the function is normalized, its all positive moments must vanish, while the physical observables depend on negative moments and the so-called log-moments. As a consequence, the model is made finite, dispersion relations hold, chiral anomalies are preserved, and the twist expansion is free from logarithmic scaling violations, as requested of a low-energy model. We study a variety of processes and show that the framework is very simple and practical. Finally, incorporating the idea of vector-meson dominance, we present an explicit construction of the quark spectral function which satisfies all the requirements. The corresponding momentum representation of the resulting quark propagator exhibits only cuts on the physical axis, with no poles present anywhere in the complex momentum space. The momentum-dependent quark mass compares very well to recent lattice calculations. A large number of predictions and relations can be deduced from our approach for such quantities as the pion light-cone wave function, non-local quark condensate, pion transition form factor, pion valence parton distribution function, etc.

description: We demonstrate a novel technique for calibrating the energy scale of the XMM EPIC-pn detector, which allows us to measure bulk flows in the intracluster medium (ICM) of the Perseus and Coma clusters. The procedure uses the instrumental lines present in all observations, in particular, Cu-Ka. By studying their spatial and temporal variations, in addition to incorporating calibration observations, we refined the absolute energy scale to better than 150 km/s at the Fe-K line, a large improvement over the nominal accuracy of 550 km/s. We then mapped the bulk motions over much of the central 1200 and 800 kpc of Perseus and Coma, respectively, in spatial regions down to 65 and 140 kpc size. We cross-checked our procedure by comparing our measurements with those found in Perseus by Hitomi for an overlapping region, finding consistent results. For Perseus, there is a LoS velocity increase of 480+-210 km/s (1sigma) 250 kpc east of the nucleus. This region is associated with a cold front, providing direct evidence of the ICM sloshing in the potential well. Assuming the intrinsic distribution of bulk motions is Gaussian, its width is 214+-85 km/s, excluding systematics. Removing the sloshing region, this is reduced to 20-150 km/s, which is similar in magnitude to the Hitomi line width measurements in undisturbed regions. In Coma, the line-of-sight velocity of the ICM varies between the velocities of the two central galaxies. Maps of the gas velocity and metallicity provide clues about the merger history of the Coma, with material to the north and east of the cluster core having a velocity similar to NGC 4874, while that to the south and west has velocities close to NGC 4889. Our results highlight the difference between a merging system, such as Coma, where we observe a ~1000 km/s range in velocity, and a relatively relaxed system, such as Perseus, with much weaker bulk motions.

Although they did not provide further data, I am quite sure that the specimen was collected by Philibert Germain as I have examined various specimens of Cassidinae with this locality data in MNHN. The exact transcription of the locality label is: ‘Brésil Rio Piracicaba P. Germain Février 1885 ’. According to Hඈඋඇ +| KൺΗඅൾ (1935), Germain collected in Brazil in the state of Minas Gerais. Consequently, the record of C. trilineata is here transferred and the species is recorded as new to Minas Gerais. However, the species is here recorded also for São Paulo as J.

Otherwise, the specimen seems to match the holotype fairly well.

description: Funds for public programmes for control of animal diseases are limited and especially so in less developed countries. Therefore it is important from an economic point of view to get the 'best value for money' from such control expenditure. After briefly reviewing the economic rationale for government intervention in control of animal diseases, this paper provides a basic analysis of the economics of optimal private and public decisions about control of animal diseases. It explores the role for cost-benefit analysis in this decision- making, taking into account informational constraints and the resource demands of multiple diseases requiring control. The analysis is illustrated by examples and issues from Thailand and pays particular attention to foot-and-mouth disease. A research proposal to help assess public programmes for the control of animal disease in Thailand is briefly sketched. The need for a dynamic approach to disease-control policy is emphasised.

description: The economic importance of livestock production has been undervalued compared to crop production and agricultural economists have not given it the attention which it deserves. Animal health is a significant influence on the productivity of livestock and the economics of animal husbandry. The range of animal health issues which can be usefully considered by economists is outlined. Some of the economic issues and problems involved in extrapolating farm-level and village-level estimates of the economic benefits of livestock disease control to the national level are outlined and discussed. The main problem is the possibility that aggregation or extrapolation of micro-data will fail to account for externalities, market changes dependant on aggregate production, such as variations in market price and changes in access to markets, such as export markets. Traditionally, cost-benefit analysis has been the most widely used technique for assessing the economics of control of animal diseases. It has been criticised by Mcinerney who suggests an alternative approach and this is considered. In conclusion, a brief outline is given of the Thai-Australian Animal Health Project (ACIAR Project 92804) which contains an economic component.

description: Relational data mining is becoming ubiquitous in many fields of study. It offers insights into behaviour of complex, real-world systems which cannot be modeled directly using propositional learning. We propose Symbolic Graph Embedding (SGE), an algorithm aimed to learn symbolic node representations. Built on the ideas from the field of inductive logic programming, SGE first samples a given node's neighborhood and interprets it as a transaction database, which is used for frequent pattern mining to identify logical conjuncts of items that co-occur frequently in a given context. Such patterns are in this work used as features to represent individual nodes, yielding interpretable, symbolic node embeddings. The proposed SGE approach on a venue classification task outperforms shallow node embedding methods such as DeepWalk, and performs similarly to metapath2vec, a black-box representation learner that can exploit node and edge types in a given graph. The proposed SGE approach performs especially well when small amounts of data are used for learning, scales to graphs with millions of nodes and edges, and can be run on an of-the-shelf laptop.

description: Outlines the basic cost-benefit analysis of Mcinerney of the optimal control of livestock diseases and presents it in a different and more readily understood form. Furthermore, this analysis is extended to discussions about the control of several diseases, for example, how to allocate available funds between the control of several diseases if net benefits are to be maximized. McInerney assumes that there is diminishing marginal net benefit from increased expenditure on the control of any livestock disease. However, this is too restrictive. It is possible that marginal net benefit at first increases and then decreases with increased expenditure on the control of some livestock diseases, and other possibilities also cannot be ruled out. The consequences of relaxing McInerney’s assumption about the nature of this net benefit curve are considered. Although it is true that indiscriminate use of benefit-cost ratios about the economics of control of livestock diseases, can lead to misleading policy advice as McInerney has claimed, they play a useful role in determining whether it is economical to control a livestock disease at all and in allocating priorities to the control of different livestock diseases. Priority should be given to controlling those diseases that are capable of yielding the highest benefit-cost ratios but it does not follow that the benefit-cost ratio of any disease targeted for control should be maximized.

We also prove that these series converge to a complex function, in a given convergence radius that we calculate. Klauder's Coherent States are explicitly found through these functions that we design by deformed exponential functions

description: The presence of magnetic noise in magnetoresistive-based magnetic sensors degrades their detection limit at low frequencies. In this paper, different ways of stabilizing the magnetic sensing layer to suppress magnetic noise are investigated by applying a pinning field, either by an external field, internally in the stack or by shape anisotropy. We show that these three methods are equivalent, could be combined and that there is a competition between noise suppression and sensitivity reduction, which results in an optimum total pinning field, for which the detection limit of the sensor is improved up to a factor of ten.

description: Generally, when imaginary part of an optical potential is non-symmetric the reflectivity, $R(E)$, shows left/right handedness, further if it is not negative-definite the reflection and transmission, $T(E)$, coefficients become anomalous in some energy intervals and absorption is indefinite ($\pm$). We find that the complex PT-symmetric potentials could be exceptional in this regard. They may act effectively like an absorptive potential for any incident energy provided the particle enters from the preferred (absorptive) side.

Level anti-crossings of an NV center in diamond: Decoherence-free subspaces and 3D sensors of microwave magnetic fields

description: Nitrogen-vacancy (NV) centers in diamond have become an important tool for quantum technologies. All of these applications rely on long coherence times of electron and nuclear spins associated with these centers. Here, we study the energy level anti-crossings of an NV center in diamond coupled to a first-shell 13C nuclear spin in a small static magnetic field. These level anti-crossings occur for specific orientations of the static magnetic field due to the strong non-secular components of the Hamiltonian. At these orientations we observe decoherence-free subspaces, where the electron spin coherence times (T_2* ) are 5-7 times longer than those at other orientations. Another interesting property at these level anti-crossings is that individual transition amplitudes are dominated by a single component of the magnetic dipole moment. Accordingly, this can be used for vector detection of microwave magnetic fields with a single NV center. This is particularly important to precisely control the center using numerical optimal control techniques.

description: Outlines a simple linear cost-benefit model for determining whether it is economic at the farm-level to vaccinate or dose a batch of livestock against a disease. This model assumes that total benefits and costs are proportional to the number of animals vaccinated. This model is then modified to allow for the possibility of programmes of vaccination or disease prevention involving start-up costs which increase, but at a decreasing rate with batch size or with the size of the herd to be vaccinated. In this case, vaccination is more likely to be profitable the larger is the herd or the batch size. Consequences of uncertainty for economic decisions about vaccination are considered. The minimax gain criterion, minimax regret criterion and expected gain criterion are applied to vaccination choices under uncertainty. Other things equal, risk-aversion or uncertainty avoidance increases the likelihood of farmers vaccinating their animals. Attention is brought to the need for research on the economics of improving estimates of the likely occurrence of livestock diseases.

 Remarks. Sඍൺංඇൾඌ +| Gൺඋർටൺ-Rඈൻඅൾൽඈ (2014) recorded this species from Argentina, Peru and Venezuela for the first time. Occurrence in Argentina is possible; however, the record must be taken with caution as the revision contains numerous misidentifications and misinterpretations. Occurrence in Peru and Venezuela is very improbable as the entire C. deyrollei species-group is restricted to eastern Brazil, and the two countries are removed from the species distribution.

Quantum line bundles on noncommutative sphere

Publisher: name: arXiv

Subjects: subject: Quantum Algebra (math.QA)

description: Noncommutative (NC) sphere is introduced as a quotient of the enveloping algebra of the Lie algebra su(2). Using the Cayley-Hamilton identities we introduce projective modules which are analogues of line bundles on the usual sphere (we call them quantum line bundles) and define a multiplicative structure in their family. Also, we compute a pairing between certain quantum line bundles and finite dimensional representations of the NC sphere in the spirit of the NC index theorem. A new approach to constructing the differential calculus on a NC sphere is suggested. The approach makes use of the projective modules in question and gives rise to a NC de Rham complex being a deformation of the classical one.

Ultra-thin, entirely flat, Umklapp lenses
Creators: name: Chaplain, Gregory J.

Publisher: name: arXiv
Year: 2019
Subjects: subject: Optics (physics.optics)
subject: FOS: Physical sciences

description: We design ultra-thin, entirely flat, dielectric lenses using crystal momentum transfer, so-called Umklapp processes, achieving the required wave control for a new mechanism of flat lensing; physically, these lenses take advantage of abrupt changes in the periodicity of a structured line array so there is an overlap between the first Brillouin zone of one medium with the second Brillouin zone of the other. At the interface between regions of different periodicity, surface, array guided, waves hybridise into reversed propagating beams directed into the material exterior to the array. This control, and redirection, of waves then enables the device to operate as a Pendry-Veselago lens that is one unit cell in width, with no need for an explicit negative refractive index. Simulations using an array embedded in a slab of silicon nitride ($\text{Si}_3\text{N}_4$) in air, operating at visible wavelengths between $420 - 500\text{THz}$ demonstrate the effect.

description: This paper is an introduction to the language of Feynman Diagrams. We use Reshetikhin-Turaev graphical calculus to define Feynman diagrams and prove that asymptotic expansions of Gaussian integrals can be written as a sum over a suitable family of graphs. We discuss how different kind of interactions give rise to different families of graphs. In particular, we show how symmetric and cyclic interactions lead to ``ordinary'' and ``ribbon'' graphs respectively. As an example, the 't Hooft-Kontsevich model for 2D quantum gravity is treated in some detail.

Assessing the Approach to Cost-Benefit Analysis of Controlling Livestock Diseases of McInerney and Others
Creators: name: Tisdell, Clem
name: Tisdell, Clem
Publisher: name: Unknown
Year: 1995
Subjects: subject: Health Economics and Policy
subject: Livestock Production/Industries
subject: Animal disease
subject: McInerney.

description: Outlines the basic cost-benefit analysis of Mcinerney of the optimal control of livestock diseases and presents it in a different and more readily understood form. Furthermore, this analysis is extended to discussions about the control of several diseases, for example, how to allocate available funds between the control of several diseases if net benefits are to be maximized. McInerney assumes that there is diminishing marginal net benefit from increased expenditure on the control of any livestock disease. However, this is too restrictive. It is possible that marginal net benefit at first increases and then decreases with increased expenditure on the control of some livestock diseases, and other possibilities also cannot be ruled out. The consequences of relaxing McInerney’s assumption about the nature of this net benefit curve are considered. Although it is true that indiscriminate use of benefit-cost ratios about the economics of control of livestock diseases, can lead to misleading policy advice as McInerney has claimed, they play a useful role in determining whether it is economical to control a livestock disease at all and in allocating priorities to the control of different livestock diseases. Priority should be given to controlling those diseases that are capable of yielding the highest benefit-cost ratios but it does not follow that the benefit-cost ratio of any disease targeted for control should be maximized.

Element segregation in giant galaxies and X-ray clusters

Publisher: name: arXiv
Year: 2003
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We examine the process of element segregation by gravity in giant elliptical galaxies and X-ray clusters. We solve the full set of flow equations developed by Burgers for a multi-component fluid, under the assumption that magnetic fields slow the diffusion by a constant factor F_B. Compared to the previous calculations that neglected the residual heat flow terms, we find that diffusion is faster by ~20%. In clusters we find that the diffusion changes the local abundance typically by factors of 1+0.3(T/10^8 K)^1.5/F_B and 1+0.15(T/10^8 K)^1.5/F_B for helium and heavy elements, respectively, where T is the gas temperature. In elliptical galaxies, the corresponding factors are 1+0.2(T/10^7 K)^1.5/F_B and 1+0.1(T/10^7 K)^1.5/F_B, respectively. If the suppression factor F_B is modest, diffusion could significantly affect observational properties of hot X-ray clusters and cD galaxies. In particular, diffusion steepens the baryon distribution, increases the total X-ray luminosity, and changes the spectrum and evolution of stars that form out of the helium-rich gas. Detection of these diffusion signatures would allow to gauge the significance of the magnetic fields, which also inhibit thermal heat conduction as a mechanism for eliminating cooling flows in the same environments.

Searching for a light Fermiophobic Higgs Boson at the Tevatron

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We propose new production mechanisms for light fermiophobic Higgs bosons ($h_f$) with suppressed couplings to vector bosons ($V$) at the Fermilab Tevatron. These mechanisms (e.g. $qq'\to H^\pm h_f$) are complementary to the conventional process $qq'\to Vh_f$, which suffers from a strong suppression of $1/\tan^2β$ in realistic models with a $h_f$. The new mechanisms extend the coverage at the Tevatron Run II to the larger $\tanβ$ region, and offer the possibility of observing new event topologies with up to 4 photons.

description: The calendar spread options (CSOs) on agricultural commodities, most notably corn, soybeans and wheat, allow market participants to hedge the roll-over risk of futures contracts. Despite the interest from agricultural businesses, there is lack of both theoretical and empirical research on pricing and hedging performances of CSOs. We propose to price and hedge CSOs under geometric Brownian motion (GBM) and stochastic volatility (SV) models. We estimate the model parameters by using implied state-generalized method of moments (IS-GMM) and evaluate the in-sample and out- of-sample pricing and hedging performances. We find that the average pricing errors of the SV model are 0.79% for corn, 0.75% for soybeans and 1.2% for wheat; the pricing and hedging performance of the SV model are mostly superior to the benchmark GBM model, both in and out of sample, with only one exception where the out-of-sample hedging error for the GBM model for market makers is slightly better than the SV model.
