Large $p$ explorations. From SUGRA to big STRINGS in Mellin space
Creators: name: Aprile, Francesco

description: We explore a new way of probing scattering of closed strings in $AdS_5\times S^5$, which we call `the large $p$ limit'. It consists of studying four-point correlators of single-particle operators in $\mathcal{N}=4$ SYM at large $N$ and large 't Hooft coupling $λ$, by looking at the regime in which the dual KK modes become short massive strings. In this regime the charge of the single-particle operators is order $λ^{1/4}$ and the dual KK modes are in between fields and strings. Starting from SUGRA we compute the large $p$ limit of the correlators by introducing an improved $AdS_5\times S^5$ Mellin space amplitude, and we show that the correlator is dominated by a saddle point. Our results are consistent with the picture of four geodesics shooting from the boundary of $AdS_5\times S^5$ towards a common bulk point, where they scatter as if they were in flat space. The Mandelstam invariants are put in correspondence with the Mellin variables and in turn with certain combinations of cross ratios. At the saddle point the dynamics of the correlator is directly related to the bulk Mellin amplitude, which in the process of taking large $p$ becomes the flat space ten-dimensional S-matrix. We thus learn how to embed the full type IIB S-matrix in the $AdS_5\times S^5$ Mellin amplitude, and how to stratify the latter in a large $p$ expansion. We compute the large $p$ limit of all genus zero data currently available, pointing out additional hidden simplicity of known results. We then show that the genus zero resummation at large $p$ naturally leads to the Gross-Mende phase for the minimal area surface around the bulk point. At one-loop, we first uncover a novel and finite Mellin amplitude, and then we show that the large $p$ limit beautifully asymptotes the gravitational S-matrix.

description: Mechanism design models typically conclude by characterizing an optimal allocation schedule based on the principal's beliefs regarding agent value functions and the distribution of agent types. This article addresses the question of how a principal can develop these beliefs given a standard cross-sectional data set in which agents' input-output choices are observable, but their underlying heterogeneity is not. I employ the methodology to evaluate strategies for reducing the cost of a voluntary program that reduces cultivation on environmentally-sensitive farmland.

description: The picosecond dynamics of hydroxyl radicals generated in 200 nm photoinduced dissociation of aqueous hydrogen peroxide have been observed through their transient absorbance at 266 nm. It is shown that these kinetics are nearly exponential, with a decay time of ca. 30 ps. The prompt quantum yield for the decomposition of H2O2 is 0.56, and the fraction of hydroxyl radicals escaping from the solvent cage to the water bulk is 64-68%. These recombination kinetics suggest strong caging of the geminate hydroxyl radicals by water. Phenomenologically, these kinetics may be rationalized in terms of the diffusion of hydroxide radicals out of a shallow potential well (a solvent cage) with an Onsager radius of 0.24 nm.

description: Conservation of biological and cultural diversity ensures human and environmental well-being. Cultural heritage sites have been recognized as a refuge for important plant species. The Peloponnese in Greece hosts especially diverse cultural heritage sites, and is characterized by high plant diversity and endemism, being one of the Mediterranean Basin’s biodiversity hotspots. However, there is a lack of studies on the vascular flora in important cultural heritage sites, including castles and their surroundings. The aim of this study is the exploration of different aspects of the flora found in culturally important castles located in the Eastern Peloponnese, with emphasis on wall and cliff plants, as well as on ruderal and alien ones. Furthermore, the assessment of the interactions of natural plant communities with cultural elements such as castles’ walls is vital for the proper management of the heritage sites and for highlighting their natural elements. Our results reveal the rich plant diversity and high degree of endemism of the areas studied. The assessment of the conservation of biodiversity in the sites studied underlines the need for proper management and sustainable use of both the cultural and natural heritage.

description: The properties of the electron-phonon interaction in the presence of a sizable electronic repulsion at finite doping are studied by investigating the metallic phase of the Hubbard-Holstein model with Dynamical Mean Field Theory. Analyzing the quasiparticle weight at finite doping, we find that a large Coulomb repulsion reduces the effect of electron-phonon coupling at low-energy, while this reduction is not present at high energy. The renormalization of the electron-phonon coupling induced by the Hubbard repul sion depends in a surprisingly strong and non-trivial way on the phonon frequency. Our results suggest that phonon might affect differently high-energy and low-energy properties and this, together with the effect of phonon dynamics, should be carefully taken into account when the effects of the electron-phonon interaction in a strongly correlated system, like the superconducting cuprates, are discussed.

Subjects: Resource /Energy Economics and Policy

description: Research was undertaken to determine the economic feasibility and environmental impact of harvesting corn stover and hardwood forest residue in Minnesota and surrounding states for conversion to fuel ethanol at facilities located in Minnesota. It was estimated that only 7 of the total 41 million dry tons of corn stover produced and 3 of the 6.5 million dry tons of hardwood residue produced in the study region would likely be harvested each year. From these quantities, it would be physically feasible to produce about 874 million gallons of ethanol annually. It was estimated that 200 million gallons could be harvested at a delivered feedstock cost below $40 per ton. Results indicate further that ethanol derived from corn stover would be cost competitive with corn-grain ethanol, and that hardwood residue-derived ethanol would be about $0.16 per-gallon higher than the upper-bound cost for corn-grain ethanol. Furthermore, this work indicates that large-scale substitution of petroleum gasoline with biomass-derived ethanol would have huge impacts with respect to reducing greenhouse gas emissions, although SOx emissions would increase.

description: The evolution of the low-lying E1 strength in proton-rich nuclei is analyzed in the framework of the self-consistent relativistic Hartree-Bogoliubov (RHB) model and the relativistic quasiparticle random-phase approximation (RQRPA). Model calculations are performed for a series of N=20 isotones and Z=18 isotopes. For nuclei close to the proton drip-line, the occurrence of pronounced dipole peaks is predicted in the low-energy region below 10 MeV excitation energy. From the analysis of the proton and neutron transition densities and the structure of the RQRPA amplitudes, it is shown that these states correspond to the proton pygmy dipole resonance.

description: In this paper, we analyze the factors that influence the productivity of maize among smallholder farmers, given that unfavourable output and input market conditions throughout the 1990s have compelled smallholder farmers into unsustainable agricultural intensification. We use farm-household survey data in order to compare the productivity of smallholder maize production under integrated (ISFM) and chemical-based soil fertility management using a normalized translog yield response model. The results indicate higher maize yield responses for integrated soil fertility management options after controlling for the intensity of fertilizer application, labour intensity, seed rate, land husbandry practices as well as selected policy factors. The estimated model is highly consistent with theoretical conditions. Thus we conclude that the use of ISFM improves maize productivity, compared to the use of inorganic fertilizer only. Since most farmers in the maize-based farming systems are crowded out of the agricultural input market and can hardly afford optimal quantities of inorganic fertilizer, enhancement of ISFM is likely to increase their maize productivity. We finally highlight areas of policy support needed to enhance ISFM uptake in smallholder maize-based farming systems.
Mixed heavy-quark-gluon condensate in the stochastic vacuum model and dual superconductor

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

description: The world-line formalism is used for the evaluation of the mixed heavy-quark-gluon condensate in two models of QCD - the stochastic vacuum model and the dual superconductor one. Calculations are performed for an arbitrary dimensionality of space-time $d\ge 2$. While in the stochastic vacuum model, the condensate is UV finite up to $d=8$, in the dual superconductor model it is UV divergent at any $d\ge 2$. A regularization of this divergence is proposed, which makes quantitative the condition of the type-II dual superconductor. The obtained results are generalized to the case of finite temperatures. Corrections to the both, mixed and standard, heavy-quark condensates, which appear due to the variation of the gauge field at the scale of the vacuum correlation length, are evaluated within the stochastic vacuum model. These corrections diminish the absolute values of the condensates, as well as the ratio of the mixed condensate to the standard one.

Vertical restraints by one manufacturer on the retailers of its product serve as an instrument to exert horizontal control over the retail price of a rival manufactured good. Applications are developed for supermarket retailing, where the manufacturer of a national brand sold at both supermarkets can employ vertical restraints to control the pricing of the retailer's competing private labels, and for the personal computer industry, where the manufacturer of an essential computer component can use vertical restraints to control the pricing of complementary components bundled with the essential component by original equipment manufacturers (OEMs).

description:

In the early 1960s, groups of artists begin to develop collective research in kinetic art and visual perception. By combining art, industrial design and technology, these ‘aesthetic operators’ lay the foundations for a multiplied art, made for everybody. The aim of their work is to open art to a genuine democratization process since the viewer would interact with these manipulable objects. However, this point of view questions the art myth of the ‘unique and unrepeatable’ artwork, which is replaced by the ‘open work’, produced in series by an interdisciplinary team. Moreover, the theory of anonymity and the multiples increase the critical debate concerning the concept of authenticity. The paper proposes a reflection on the diffusion of multiplied art during the 1960s. Through the analysis of the archival documents – some previously unpublished – the study identifies the crucial passages in which the experimentations of programmed Italian artists have embraced the democratic ideology of seriality.

description: Hundreds of popular mobile apps today market their ties to mindfulness. What activities do these apps support and what benefits do they claim? How do mindfulness teachers, as domain experts, view these apps? We first conduct an exploratory review of 370 mindfulness-related apps on Google Play, finding that mindfulness is presented primarily as a tool for relaxation and stress reduction. We then interviewed 15 U.S. mindfulness teachers from the therapeutic, Buddhist, and Yogic traditions about their perspectives on these apps. Teachers expressed concern that apps that introduce mindfulness only as a tool for relaxation neglect its full potential. We draw upon the experiences of these teachers to suggest design implications for linking mindfulness with further contemplative practices like the cultivation of compassion. Our findings speak to the importance of coherence in design: that the metaphors and mechanisms of a technology align with the underlying principles it follows.

Constructed destinations : art and representations of history at the Vancouver International Airport
Creators: name: Rorke, Rosalind Alix
Publisher: name: University of British Columbia
Year: 2009

description: Since its opening in 1931, the Vancouver International Airport has been a site where significant representations of the city, its geography and its population have been made. Instead of being utilitarian structures the airport terminals have been purposefully designed and decorated with art chosen specifically to communicate Vancouver's distinct qualities and culture to travelers. As culture is never static and changes continuously, the representations have also shifted over time. By considering the specific history of Vancouver's airport in conjunction with the wider history of Canadian and international airport development, patterns (such as the continuous use of symbols from native cultures to represent aspects of the colonizer's culture) and tensions (such as Vancouver's relative position as a major Canadian urban centre and the growth of visible immigrant populations) which accompany the representation of locality at the airport become apparent. Henri Lefevbre's understanding of space as an active social product, David Harvey's assessment of the impact of globalization upon the local and Siegfried Kracauer's interpretation of architecture as illustrative of broad social trends underpin my analysis. The adoption,of an historical and theoretical framework within this thesis is directed at developing an interpretation of the current art program at the Vancouver International Airport which can move beyond the point where debate regarding "authenticity" and the agency of the native artists or their communities constricts the discussion. Through an examination of airport design, both theoretical and actual, the genesis of and reactions to art programs executed at the airport since the 1960s, as well as aspects of the city's social history, I illustrate that the current art program is representative of more than a superficial thematic strategy. Instead, it points to a complex and ongoing struggle to define and represent Vancouver both to its residents and the rest of the world.

description: In the late 1960s the discovery of the Crab pulsar in its associated supernova remnant, launched a new field in supernova remnant research: the study of pulsar-driven or plerionic supernova remnants. In these type of remnants, the relativistic wind emitted by the pulsar, blows a pulsar wind nebula into the interior of its supernova remnant. Now, more then forty years after the discovery of the Crab pulsar, there are more then fifty plerionic supernova remnants known, due to the ever-increasing capacity of observational facilities. I will review our current understanding of the different evolutionary stages of a pulsar wind nebula as it is interacting with its associated supernova remnant.Therefore I will discuss both analytical and more recent numerical (M)HD models.The four main stages of a pulsar wind nebula are: the supersonic expansion stage, the reverse shock interaction stage, the subsonic expansion stage and ultimatelythe stage when the head of the bubble is bounded by a bow shock, due to the supersonic motion of the pulsar. Ultimately this pulsar wind nebula bow shock will break through its associated remnant, after which the pulsar-powered bow shock will interact directly with the interstellar medium. I will discuss recent numerical models from these type of pulsar wind nebulae and their morphology.

The approximations of the construction method are critically analyzed using the example of oxygen for which more detailed computations are available. An effective description of nucleus based on the information contained in a spectral function is proposed. It is demonstrated that its predictions are close to those obtained from the complete spectral function. The effective description can be easily applied in Monte Carlo event generators.

description: Big Ridge State Park (BRSP), located in Union County on Norris Lake in East Tennessee, is one of 56 Tennessee state parks. The park employs 12 individuals full time, and 10 additional individuals are seasonal. Provided here are estimates of the economic contribution of BRSP to the four-county (Anderson, Knox, Grainger and Union Counties) economy in which it resides. These estimates include the current contribution of the park and the park’s contribution after improvements to park assets (remodeling cabins, adding bike trails, new restrooms, a water trail with a launch area, and new campsites). An IMPLAN-based input-output model of the four-county economy was used to provide an estimate of the total (direct and with multiplier effects) economic impact of improvements to Big Ridge State Park. Three types of economic impacts are estimated in this analysis — the current level of impact, the impact of investments in improvements to the park, and the impact of attracting new visitors because of the investments. The current impact consists of BRSP expenditures and those of the current visitors. It is estimated that the current impact level to the four-county region consisting of Anderson, Grainger, Knox and Union Counties is $21.7 million. By a one-time investment of $7.3 million in the park’s assets, another $3 million to $5 million economic impact could result each year to the regional economy through the attraction of nonlocal visitors. In addition, the investment of $3.5 million to $6.8 million would provide a one-time economic impact to the region of $6.6 million to $14.0 million, along with 53 to126 jobs, depending on whether the low or high bike trail estimate is used.

description: Sulfur-water chemistry plays an important role in the middle atmosphere of Venus. Ground based observations have found that simultaneously observed SO2 and H2O at ~64 km vary with time and are temporally anti-correlated. To understand these observations, we explore the sulfur-water chemical system using a one-dimensional chemistry-diffusion model. We find that SO2 and H2O mixing ratios above the clouds are highly dependent on mixing ratios of the two species at the middle cloud top (58 km). The behavior of sulfur-water chemical system can be classified into three regimes but there is no abrupt transition among these regimes. In particular, there is no bifurcation behavior as previously claimed. We also find that the SO2 self-shielding effect causes H2O above the clouds to respond to the middle cloud top in a non-monotonic fashion. Through comparison with observations, we find that mixing ratio variations at the middle cloud top can explain the observed variability of SO2 and H2O. The sulfur-water chemistry in the middle atmosphere is responsible for the H2O-SO2 anti-correlation at 64 km. Eddy transport change alone cannot explain the variations of both species. These results imply that variations of species abundance in the middle atmosphere are significantly influenced by the lower atmospheric processes. Continued ground-based measurements of the co-evolution of SO2 and H2O above the clouds and new spacecraft missions will be crucial for uncover the complicated processes underlying the interaction among the lower atmosphere, the clouds and the middle atmosphere of Venus.

The spectra exhibit a significant dependence on the incident photon energy which we carefully utilize to resolve a multiplet of weakly-dispersive ($ < 0.5$ eV) electron-hole excitations, including a mode at 2 eV. The observation of this 2 eV excitation suggests the existence of a charge-transfer pseudogap deep in the superconducting phase. Quite generally, our data demonstrate the importance of exploring the incident photon energy dependence of the RIXS cross section.

description: In the forthcoming large volume galaxy surveys higher order statistics will provide complementary information to the usual two point statistics. Low variance estimators of the Three Point Correlation Function (3CPF) of discrete data count triangle configurations with vertices mixing data and random catalogues. Large density random catalogues are used to reduce the shot noise, which leads to a computational cost of one or two orders of magnitude more than the pure data histogram. In this paper, we explore time reductions of the isotropic 3PCF random sampling terms in periodic boxes without using random catalogues. In the first approach, based on Hamilton's construction of his famous two point estimator, we use an ad-hoc two point correlation term, while for the second procedure we construct the operators from a geometrical viewpoint, using two sides and their opening angle to describe the 3PCF triangle configurations. We map the last result to the three triangle side basis either numerically or analytically, and show that the latter approach performs best when applied to synthetic data. Moreover, we elaborate on going beyond periodic boxes, discuss other low variance n-point estimators and present useful 3PCF visualization schemes.

description:

Writing and dance have been positioned by scholars in a contraposed play throughout the chronological period from the Renaissance to today: dancing begins when writing stops. Scholars have accused dance of ephemerality and have attempted to salvage it through notation. In postmodern and contemporary dance, some choreographers challenge traditional assumptions about the primacy and stability of text and documentation. They ‘write’ with dance in both conceptual and alphabetic ways, some exploring the dimension of race. This study tests theories by Mark Franko and André Lepecki through analysis of dance reenactment strategies and interventions by choreographers Trisha Brown and Christopher-Rasheem McMillan.

Episodes narrated in art history primary sources are compared with twentieth and twenty-first-century episodes. Thus, one comes to the notion of fake in contemporaneity, which no longer has a negative meaning. On the contrary, it has become an acknowledged artistic practice, a means that reveals the mise-en-scène that each image represents by declaring itself as ‘true’. Also, the notion of a ‘second original’, obtained thanks to contemporary technologies, calls into question the Benjaminian notion of the artwork’s ‘aura’.

description: We take the manifestly gauge invariant exact renormalisation group previously used to compute the one-loop beta function in SU(N) Yang-Mills without gauge fixing, and generalise it so that it can be renormalised straightforwardly at any loop order. The diagrammatic computational method is developed to cope with general group theory structures, and new methods are introduced to increase its power, so that much more can be done simply by manipulating diagrams. The new methods allow the standard two-loop beta function coefficient for SU(N) Yang-Mills to be computed, for the first time without fixing the gauge or specifying the details of the regularisation scheme.

La figura di Daniele Farsetti collezionista negli epistolari

description:

The last setting of the Farsetti picture gallery, the least studied part of the collection owned by this Venetian family, was already attributed to Daniele. Now, two unpublished letters written by Daniele to the Bergamasque Sebastiano Muletti not only confirm his role, but also portray a figure of connoisseur of manuscripts, printed books, artistic literature and, of course, painting. It seems that two main motivations led Daniele in his purchases of paintings: their presence in artistic literature and their state of preservation. These criteria were broadly recognised in late eighteenth-century Venice.

description: Goldstone Apple Valley Radio Telescope (GAVRT) is a science education partnership among NASA, the Jet Propulsion Laboratory (JPL), and the Lewis Center for Educational Research (LCER), offering unique opportunities for K -12 students and their teachers. As part of a long-term Jupiter synchrotron radiation (JSR) flux density monitoring program, LCER has been carrying out Jupiter observations with some student participation. In this paper we present the results of processed data sets observed between March 6, 2015 and April 6 2018. The data are divided into 5 epochs, grouped by time. We derive JSR beaming curves at different epochs and Earth declinations. We present a comparison of the observed beaming curves with those derived from most recent models for the radiation belts. Our results show an increasing trend of the JSR flux density which seem consistent with the models for the magnetospheric solar wind interactions.

description: Lithium metal penetrations through the liquid-electrolyte-wetted porous separator and solid electrolytes are a major safety concern of next-generation rechargeable metal batteries. The penetrations were frequently discovered to occur through only a few isolated channels, as revealed by "black spots" on both sides of the separator or electrolyte, which manifest a highly localized ionic flux or current density. Predictions of the penetration time have been infeasible due to the hidden and unclear dynamics in these penetration channels. Here, using the glass capillary cells, we investigate for the first time the unexpectedly sensitive influence of channel geometry on the concentration polarization and dendrite initiation processes. The characteristic time for the complete depletion of salt concentration on the surface of the advancing electrode, i.e. Sand's time, exhibits a nonlinear dependence on the curvature of the channel walls along the axial direction. While a positively deviated Sand's time scaling exponent can be used to infer a converging penetration area through the electrolyte, a negatively deviated scaling exponent suggests that diffusion limitation can be avoided in expanding channels, such that the fast-advancing tip-growing dendrites will not be initiated. The safety design of rechargeable metal batteries will benefit from considering the true local current densities and the conduction structures.

description: We propose a novel scheme to efficiently polarize and manipulate the electron spin in a quantum dot. This scheme is based on the spin-orbit interaction and it possesses following advantages: (1) The direction and the strength of the spin polarization is well controllable and manipulatable by simply varying the bias or the gate voltage. (2) The spin polarization is quite large even with a weak spin-orbit interaction. (3) Both electron-electron interaction and multi-energy levels do not weaken but strengthen the spin polarization. (4) It has the short spin flip time. (5) The device is free of a magnetic field or a ferromagnetic material. (6) It can be easily realized with present technology.

Pulsed-pump phosphorus-doped fiber Raman amplifier around 1260 nm for applications in quantum non-linear optics

description: We describe a fiber Raman amplifier for nanosecond and sub-nanosecond pulses centered around 1260 nm. The amplification takes place inside a 4.5-m-long polarization-maintaining phosphorus-doped fiber, pumped at 1080 nm by 3-ns-long pulses with a repetition rate of 200 kHz and up to 1.75 kW peak power. The input seed pulses are of sub-mW peak-power and minimal duration of 0.25 ns, carved off a continuous-wave laser with sub-MHz linewidth. We obtain linearly-polarized output pulses with peak-powers of up to 1.4 kW, corresponding to peak-power conversion efficiency of over 80%. An ultrahigh small-signal-gain of 90 dB is achieved, and the signal-to-noise ratio 3 dB below the saturation power is above 20 dB. No significant temporal and spectral broadening is observed for output pulses up to 400 W peak power, and broadening at higher powers can be reduced by phase modulation of the seed pulse. Thus nearly-transform-limited pulses with peak power up to 1 kW are obtained. Finally, we demonstrate the generation of pulses with controllable frequency chirp, pulses with variable width, and double pulses. This amplifier is thus suitable for coherent control of narrow atomic resonances and especially for the fast and coherent excitation of rubidium atoms to Rydberg states. These abilities open the way towards several important applications in quantum non-linear optics.

description: The concept of stochastic dominance is described and its use is illustrated in relation to the evaluation of the output of a systems simulation model of lucerne haymaking in south-west Spain. Two alternative machinery systems are ranked for various lucerne areas using the criteria of stochastic dominance, and These results are compared with those obtained using mean-variance analysis.
Capacity-Achieving Ensembles of Accumulate-Repeat-Accumulate Codes for the Erasure Channel with Bounded Complexity

description: The paper introduces ensembles of accumulate-repeat-accumulate (ARA) codes which asymptotically achieve capacity on the binary erasure channel (BEC) with {\em bounded complexity}, per information bit, of encoding and decoding. It also introduces symmetry properties which play a central role in the construction of capacity-achieving ensembles for the BEC with bounded complexity. The results here improve on the tradeoff between performance and complexity provided by previous constructions of capacity-achieving ensembles of codes defined on graphs. The superiority of ARA codes with moderate to large block length is exemplified by computer simulations which compare their performance with those of previously reported capacity-achieving ensembles of LDPC and IRA codes. The ARA codes also have the advantage of being systematic.

description: The objectives of this paper are two-fold. The first is to discuss the basic economics of an aggregate industry income stabilization policy for primary producers. The second is to examine post-World War II income instability in Australian wool, wheat, and beef and to apportion it into its price and output components. This analysis provides a basis for discussing income stabilization in the Australian context.
