description: We determine the upper limit on the mass of the lightest neutrino from the most robust recent cosmological and terrestrial data. Marginalizing over possible effective relativistic degrees of freedom at early times ($N_\mathrm{eff}$) and assuming normal mass ordering, the mass of the lightest neutrino is less than 0.037 eV at 95% confidence; with inverted ordering, the bound is 0.042 eV. These results improve upon the strength and robustness of other recent limits and constrain the mass of the lightest neutrino to be barely larger than the largest mass splitting. We show the impacts of realistic mass models, and different sources of $N_\mathrm{eff}$.

description: We review the aging phenomenon in the context of the simplest trap model, Bouchaud's REM-like trap model, from a spectral theoretic point of view. We show that the generator of the dynamics of this model can be diagonalized exactly. Using this result, we derive closed expressions for correlation functions in terms of complex contour integrals that permit an easy investigation into their large time asymptotics in the thermodynamic limit. We also give a ``grand canonical'' representation of the model in terms of the Markov process on a Poisson point process. In this context we analyze the dynamics on various time scales.

description: We study the addition of flavor degrees of freedom to the supergravity dual of the non-commutative deformation of the maximally supersymmetric gauge theories. By considering D7 flavor branes in the probe approximation and studying their fluctuations we extract the spectrum of scalar and vector mesons as a function of the non-commutativity. We find that the spectrum for very large non-commutative parameter is equal to the one in the commutative theory, while for some intermediate values of the non-commutativity some of the modes disappear from the discrete spectrum. We also study the semiclassical dynamics of rotating open strings attached to the D7-brane, which correspond to mesons with large spin. Under the effect of the non-commutativity the open strings get tilted. However, at small(large) distances they display the same Regge-like (Coulombic) behaviour as in the commutative theory. We also consider the addition of D5-flavor branes to the non-commutative deformation of the N=1 supersymmetric Maldacena-Nunez background.

A Study of the Properties and Performance of Kentucky (Natural Sandstone) Rock Asphalt
Creators: name: Havens, James H.

Publisher: name: Kentucky Transportation Center, University of Kentucky
Year: 1956
Subjects: subject: Transportation Engineering

description: Kentucky (natural sandstone) rock asphalt derives its esteem as a highway surfacing material from its uniform appearance on the road, its riding characteristics, and the fact that it affords the highest protection against skidding (slipperiness) of any of the paving materials now generally available (see Appendix IV). The usual methods of handling, steaming, laying and spreading offer some of the conveniences and advantages of a ready-to-use material. Although its service history during the past 50 years has been generally favorable, there has also been a certain amount of risk involved in its use, particularly in recent years on roads sustaining heavy loadings and high volumes of traffic.

description: We demonstrate long-range superconducting correlations in a several micrometer-long carbon nanotube encapsulated in a van der Waals stack between hBN and NbSe$_2$. We show that a substantial supercurrent flows through the nanotube section beneath the NbSe$_2$ crystal as well as through the 2 $μ$m-long section not in contact with it. As expected for superconductors of nanoscopic cross section, the current-induced breakdown of superconductivity is characterized by resistance steps due to the nucleation of phase slip centers. All elements of our hybrid device are active building blocks of several recently proposed setups for realization of Majorana fermions in carbon nanotubes.

Universal Axion Backreaction in Flux Compactifications

Subjects: subject: High Energy Physics - Theory (hep-th)

description: We study the backreaction effect of a large axion field excursion on the saxion partner residing in the same $\mathcal{N}=1$ multiplet. Such configurations are relevant in attempts to realize axion monodromy inflation in string compactifications. We work in the complex structure moduli sector of Calabi-Yau fourfold compactifications of F-theory with four-form fluxes, which covers many of the known Type II orientifold flux compactifications. Noting that axions can only arise near the boundary of the moduli space, the powerful results of asymptotic Hodge theory provide an ideal set of tools to draw general conclusions without the need to focus on specific geometric examples. We find that the boundary structure engraves a remarkable pattern in all possible scalar potentials generated by background fluxes. By studying the Newton polygons of the extremization conditions of all allowed scalar potentials and realizing the backreaction effects as Puiseux expansions, we find that this pattern forces a universal backreaction behavior of the large axion field on its saxion partner.

Transverse velocities, intermittency and asymmetry in fully developed turbulence

Publisher: name: arXiv
Year: 2005
Subjects: subject: Chaotic Dynamics (nlin.CD)
subject: FOS: Physical sciences

description: Using experimental transverse velocities data for very high Reynolds number turbulence, we suggest a model describing both formation of intermittency and asymmetry of turbulence. The model, called "bump-model" is a modification of ramp-model suggested earlier, S.I. Vainshtein and K.R. Sreenivasan, Phys. Rev. Lett., 73, 3085 (1994). The connection between asymmetry and intermittency makes it possible to study the latter with relatively low moments.

description: We explore the effect of using two-dimensional matter-wave vortices to confine an ensemble of bosonic quantum impurities. This is modelled theoretically using a mass-imbalanced homogeneous two component Gross-Pitaevskii equation where each component has independent atom numbers and equal atomic masses. By changing the mass imbalance of our system we find the shape of the vortices are deformed even at modest imbalances, leading to barrel shaped vortices; which we quantify using a multi-component variational approach. The energy of impurity carrying vortex pairs are computed, revealing a mass-dependent energy splitting. We then compute the excited states of the impurity, which we in turn use to construct `covalent bonds' for vortex pairs. Our work opens a new route to simulating synthetic chemical reactions with superfluid systems.

description: We study five dimensional(5D) spherically symmetric self-similar perfect fluid space-time with adiabatic equation of state, considering all the families of future directed non-spacelike geodesics. The space-time admits globally strong curvature naked singularities in the sense of Tipler and thus violates the cosmic censorship conjecture provided a certain algebraic equation has real positive roots. We further show that it is the weak energy condition (WEC) that is necessary for visibility of singularities for a finite period of time and for singularities to be gravitationally strong. We, also, match the solution to 5D Schwarzschild solution using the junction conditions.

description: When the Standard Model Higgs sector is extended with a complex singlet that breaks global lepton number symmetry spontaneously, a massless Goldstone boson called the Majoron J arises. In addition to increasing Higgs invisible decay through mixing, the Majoron can generally have flavor-changing interactions with fermions. We find that type-III seesaw model poses such interesting properties with both charged leptons and neutrinos. This opens up new channels to search for the Majoron. We use the experimental data such as muonium-anti-muonium oscillation and flavor-changing neutrino and charged lepton decays to put constraints on the couplings. As a novel way to reveal the chiral properties of these interactions, we propose an experimentally measurable polarization asymmetry of flavor-changing l to l' J decays.

description: The advantages and limitations of solar photovoltaic (PV) systems for energy generation are reviewed under various physical efficiency limits, operational design and financial assistance programs. Recent increases in utility and fuel costs in poultry production as well as public awareness of and demand for green power or renewable energy sources has given renewed interest in alternative energy sources. This study seeks to investigate the impact of alternative energy programs, grants and other incentives on the feasibility of solar PV systems in two solar regions within Tennessee's poultry industry. Preliminary results show that incentives must exceed current levels before adoption of solar PV systems would be financially beneficial.

description: The resonant interaction between quasi-one dimensional excitons and photons is investigated. For a single isolated organic quantum wire, embedded in its single crystal monomer matrix, the strong exciton-photon coupling regime is reached. This is evidenced by the suppression of the resonant excitonic absorption arising when the system eigenstate is a polariton. These observations demonstrate that the resonant excitonic absorption in a semiconductor can be understood in terms of a balance between the exciton coherence time and the Rabi period between exciton-like and photon-like states of the polariton.

description: Federal, state and local governments have funded various efforts to support value added agriculture, often implicitly assuming that the enterprises would be profitable and that the transition from commodity producer to producer-processor-marketer-distributor would be relatively easy. Some analysts (e.g., Streeter and Bills; 2003a, 2003b) have questioned both of these assumptions, noting that available aggregate data do not allow assessment of the financial performance of value-added enterprises. Our study collected detailed financial information from 27 value-added dairy enterprises with cows, goats or sheep in three states. These businesses processed and marketed cheese, fluid milk products and yogurt; 17 had begun processing during the previous three years. The financial information was used to develop income statements and balance sheets for both the milk production and the dairy processing and marketing enterprises. Our results suggest that value-added dairy is not a panacea: despite much higher revenues per unit milk produced or processed, mean net income for the processing enterprise and for the combined milk production and processing business were modest at best and often negative. More than half of the on-farm processors had negative net incomes from processing, and seven processing enterprises had negative net worth. On average, returns per cwt milk processed were $90 per cwt and $209 per cwt (for cow and goat/sheep milk producers, respectively) lower than the full economic costs of production and processing.

description: Information on the spatial distribution of poverty can be useful in designing geographically targeted rural poverty reduction programs. This paper uses recently released município-level data on rural poverty in Brazil to identify and analyze spatial patterns of rural poverty in the São Francisco River Basin (SFRB). Moran's I statistics are generated and used to test for spatial autocorrelation, and to prepare cluster maps that locate rural poverty 'hot spots' and 'cold spots.' Research results demonstrate that rural poverty is spatially correlated in some parts of the SFRB, and where correlated, worse-off (better-off) municípios tend to be located next to worse-off (better-off) municípios. The policy implications of these results are discussed, as are proposed next steps in research.

To do so, we introduce the notion of interval-valued moderate deviation function and we study in particular those interval-valued moderate deviation functions which preserve the width of the input intervals. Then, we study how to apply these functions to construct interval-valued aggregation functions. We have applied them in the decision making phase of two Motor-Imagery Brain Computer Interface frameworks, obtaining better results than those obtained using other numerical and intervalar aggregations.

description: This paper estimates treatment effects of two active labor market policies – a
training program and a wage subsidy scheme – on participants' employment probabilities.
The analysis is based on unique data from the 18th wave of the Polish Labor Force Survey
containing detailed and extensive individual labor force status histories. We discuss two
variants of an exact covariate matching procedure adapted to the specific nature of the
data. Our study confirms and reinforces a point raised in recent research (Heckman and
Smith 1999, 2004), that pre-treatment labor force status dynamics play a decisive role in
determining program participation. We implement a conditional difference-in-differences
estimator of treatment effects based on these individual trinomial sequences of pretreatment
labor market status. The estimator employs a “moving window” technique that
nicely controls for changes in the macroeconomic environment over time. Our findings
suggest that training raises individual employment probability, while wage subsidies display
negative treatment effects for participants in the Polish case.

description: We present a novel approach to pseudo-feedback-based ad hoc retrieval that uses language models induced from both documents and clusters. First, we treat the pseudo-feedback documents produced in response to the original query as a set of pseudo-queries that themselves can serve as input to the retrieval process. Observing that the documents returned in response to the pseudo-queries can then act as pseudo-queries for subsequent rounds, we arrive at a formulation of pseudo-query-based retrieval as an iterative process. Experiments show that several concrete instantiations of this idea, when applied in conjunction with techniques designed to heighten precision, yield performance results rivaling those of a number of previously-proposed algorithms, including the standard language-modeling approach. The use of cluster-based language models is a key contributing factor to our algorithms' success.

description: We take a game theory approach to study the make-or-buy decisions of firms in a
mixed duopoly. We assume that a managerial firm and a profit-oriented firm compete in a
duopoly market for a final good, and they can choose whether making an intermediate input or
buying it from a monopolistic upstream firm. We find that different equilibria may arise,
depending on parameter constellations. In particular, if the technology used for the production
of the intermediate input is too costly, then the internal organization of firms at equilibrium is
mixed, creating a conflict with social preferences that would always privilege vertical
integration to outsourcing.

description: This study provides a new framework of analysis of the market and welfare effects of mandatory country of origin labeling (MCOOL) for fruits and vegetables that accounts for heterogeneous consumer preferences for domestic products, differences in producer agronomic characteristics, and retailer market power when buying and selling these products. The market and welfare effects of MCOOL are shown to be case-specific and dependent on the labeling costs at the farm and retail levels, the strength of consumer preference for domestic products, the market power of retailers, the marketing margin along the supply chain, and the relative costs of imported and domestic products. Simulation results for the US markets of apples and tomatoes indicate that for the regulation to increase total economic welfare in these markets, the consumer demand after MCOOL would need to increase by 2.6% to 7.0% for domestic apples and by 8.2% to 22.4% for domestic tomatoes, depending on the market power of retailers and the size of the labeling costs.

description: In this paper we consider the energy and momentum transport in (1+1)-dimension conformal field theories (CFTs) that are deformed by an irrelevant operator $T\bar{T}$, using the integrability based generalized hydrodynamics, and holography. The two complementary methods allow us to study the energy and momentum transport after the in-homogeneous quench, derive the exact non-equilibrium steady states (NESS) and calculate the Drude weights and the diffusion constants. Our analysis reveals that all of these quantities satisfy universal formulae regardless of the underlying CFT, thereby generalizing the universal formulae for these quantities in pure CFTs. As a sanity check, we also confirm that the exact momentum diffusion constant agrees with the conformal perturbation. These fundamental physical insights have important consequences for our understanding of the $T\bar{T}$-deformed CFTs. First of all, they provide the first check of the $T\bar{T}$-deformed $\mathrm{AdS}_3$/$\mathrm{CFT}_2$ correspondence from the dynamical standpoint. And secondly, we are able to identify a remarkable connection between the $T\bar{T}$-deformed CFTs and reversible cellular automata.

description: We study the elliptic flow coefficient v_2(eta,b) in Au+Au collisions at sqrt(s)=200 A GeV as a function of pseudorapidity eta and impact parameter b. Using a hybrid approach which combines early ideal fluid dynamical evolution with late hadronic rescattering, we demonstrate strong dissipative effects from the hadronic rescattering stage on the elliptic flow. With Glauber model initial conditions, hadronic dissipation is shown to be sufficient to fully explain the differences between measured v_2 values and ideal hydrodynamic predictions. Initial conditions based on the Color Glass Condensate model generate larger elliptic flow and seem to require additional dissipation during the early quark-gluon plasma stage in order to achieve agreement with experiment.

description: In this work we introduce a generalization of the Jauch and Rohrlich quantum Stokes operators when the arrival direction from the source is unknown {\it a priori}. We define the generalized Stokes operators as the Jordan-Schwinger map of a triplet of harmonic oscillators with the Gell-Mann and Ne'eman SU(3) symmetry group matrices. We show that the elements of the Jordan-Schwinger map are the constants of motion of the three-dimensional isotropic harmonic oscillator. Also, we show that generalized Stokes Operators together with the Gell-Mann and Ne'eman matrices may be used to expand the polarization density matrix. By taking the expectation value of the Stokes operators in a three-mode coherent state of the electromagnetic field, we obtain the corresponding generalized classical Stokes parameters. Finally, by means of the constants of motion of the classical three-dimensional isotropic harmonic oscillator we describe the geometric properties of the polarization ellipse

description: In this work we study the nature of correlations among mixed states in the setup of two symmetric strips. We use various tools to determine how the bulk geometry could be reconstructed from the boundary mixed information. These tools would be the modular Hamiltonian and modular flow, OPE blocks, quantum recovery channels such as Petz map, Uhlmann holonomy and Wilson lines. We comment on the similarities and connections between these approaches in our symmetric setup of a mixed system. Specially, we use parameters such as dissipation which is being modeled by the mass of graviton, and also the same sign charge of the two strips to find connections between these different approaches. Then, using Uhlmann fidelity as the correlation measure, we look into the various types of correlations in mixed systems such as discord. Next, we use simple results of modular Hamiltonian for fermions to get insights about the relations between modular flow and entanglement and complexity of purification (EoP/CoP), and also behavior of modular flows in confining geometries. Finally, we study the dynamics of correlations using various information speeds and also model of void formation in CFTs and again we comment on their relationships with the behavior of EoP and CoP.

description: In this paper we assess the appeal of potential interventions on the tourism offer of Rimini, a popular
Italian seaside holiday destination, by means of a choice modelling analysis. Tourism can be viewed as
a composite good, its overall utility depending on the arrangement of the component characteristics.
Our discrete choice experiments incorporate as attributes a number of possible changes to current
tourist activities (the subject of public debate), including them in hypothetical alternative holiday
packages. The conditional logit analysis indicates that tourists show lesser preference for interventions
aimed at protecting the environmental integrity of the beach and greater preference for those, such as
the creation of a pedestrianised seafront with late-night opening of amenities and facilities, that are
likely to diminish the role of the traditional sea, sun and sand component of the overall holiday
experience.

description: The objective of this analysis is to describe and, if possible, measure gains that farmland owners may have seen because of the public's demand for wetland services. To do so, we first consider landowners' ability to directly sell onsite (hunting, fishing, wildlife viewing) and offsite (water quality, groundwater recharge, etc.) wetland services. We found little evidence that landowners sell wetland services. We then consider farmland owners' gains from the mitigation banking system. We found that, with less than 200 approved mitigation banks on farmland, farmland owners had some but limited opportunities to participate in mitigation markets. Finally, we consider landowners' gains from the sale of wetland easements through the USDA's Wetland Reserve Program (WRP). Although we are unable to quantify any gains, the popularity of the program suggests that landowners do gain by participating - since the mid-1990's, more landowners have tried to enroll than program limits allow. Furthermore, two factors suggest that WRP gains are widespread. First, WRP easements have been sold in every State. And second, easement prices have increased over time which may indicate that owners of higher-valued lands may be seeing opportunities to participate.

description: When a high power laser beam irradiates a small aperture on a solid foil target, the strong laser field drives surface plasma oscillation at the periphery of this aperture, which acts as a "relativistic oscillating window". The diffracted light that travels though such an aperture contains high-harmonics of the fundamental laser frequency. When the driving laser beam is circularly polarised, the high-harmonic generation (HHG) process facilitates a conversion of the spin angular momentum of the fundamental light into the intrinsic orbital angular momentum of the harmonics. By means of theoretical modeling and fully 3D particle-in-cell simulations, it is shown the harmonic beams of order $n$ are optical vortices with topological charge $|l| = n-1$, and a power-law spectrum $I_n\propto n^{-3.5}$ is produced for sufficiently intense laser beams, where $I_n$ is the intensity of the $n$th harmonic. This work opens up a new realm of possibilities for producing intense extreme ultraviolet vortices, and diffraction-based HHG studies at relativistic intensities.

description: The Co Knight shift was measured in an aligned powder sample of Na_xCoO_2yH_2O, which shows superconductivity at T_c \sim 4.6 K. The Knight-shift components parallel (K_c) and perpendicular to the c-axis (along the ab plane K_{ab}) were measured in both the normal and superconducting (SC) states. The temperature dependences of K_{ab} and K_c are scaled with the bulk susceptibility, which shows that the microscopic susceptibility deduced from the Knight shift is related to Co-3d spins. In the SC state, the Knight shift shows an anisotropic temperature dependence: K_{ab} decreases below 5 K, whereas K_c does not decrease within experimental accuracy. This result raises the possibility that spin-triplet superconductivity with the spin component of the pairs directed along the c-axis is realized in Na_xCoO_2yH_2O.

description: The increased prevalence of childhood obesity is a major concern for society. This study aims at exploring the influence of the parents (especially parental time allocation choices) on children's obesity-related health outcomes and examining the potential differences between the fathers' and the mothers' marginal effects. A household with two parents and one child is modeled. The household production theory and the collective household modeling structure are combined. The model treats the mother, the father and the child as three separate agents with individual preferences. The two parents' interaction is modeled within the collective model framework by assuming that they will reach Pareto efficient resource allocation between them. In order to capture the dynamics between parents and the child, parents-child interaction is modeled in a two-stage Stackleberg game structure where the child is allowed to have certain decision choices of his/her own. This game structure allows us to explore the parental influence on the child's health outcomes while allowing the child to have influencing power in the household decision-making process. Based on this theoretical model, a general triangular system with one child's health production equation and five health inputs demand equations is derived and estimated. The empirical estimation is performed for three systems: pooled model, the younger children model (of age 9 to 11), and the older children model (of age 13 to 15). The empirical results shows positive relationship between total household monthly food expenditure and the child's BMI outcome. Both parents' time spent with the child are important and both show negatively significant impact on the child's BMI outcomes in all models and the pool model confirms the statistical difference between paternal and maternal time spent with the child. Other mother-related variables show more influence on the children's BMI. There exists a complementary relationship between mothers' income and fathers' time allocation. Fathers have more significant influence on household food expenditure compared to mothers. In general, mothers' show more significant influence on the parental time allocation compared to fathers. The main contribution of this study is that it develops a general theoretical framework to capture the dynamics in parents-child interaction. Based on this theoretical model, empirical analysis and future work can be conducted in a theoretically consistent way.
How enforcement institutions affect markets

description: In an experiment we study market outcomes under alternative incentive structures for thirdparty
enforcers. Our transactions resemble an anonymous credit market where lenders can give
loans and borrowers can repay them. When borrowers default, judges are free to enforce repayment
but are themselves paid differently in each of three treatments. First, paying judges according to
lenders’ votes maximizes surplus and the equality of earnings. In contrast, paying judges according
to borrowers’ votes triggers insufficient enforcement, destroying the market and producing the
lowest surplus and the most unequal distribution of earnings. Lastly, judges paid the average
earnings of borrowers and lenders achieve results close to those based on lender voting. We employ
a steps-of-reasoning argument to interpret the performances of different institutions. When voting
and enforcement rights are allocated to different classes of actors, the difficulty of their task
changes, and arguably as a consequence they focus on high or low surplus equilibria.
Explosion phenomena in stochastic coagulation-fragmentation models

description: First we establish explosion criteria for jump processes with an arbitrary locally compact separable metric state space. Then these results are applied to two stochastic coagulation-fragmentation models--the direct simulation model and the mass flow model. In the pure coagulation case, there is almost sure explosion in the mass flow model for arbitrary homogeneous coagulation kernels with exponent bigger than 1. In the case of pure multiple fragmentation with a continuous size space, explosion occurs in both models provided the total fragmentation rate grows sufficiently fast at zero. However, an example shows that the explosion properties of both models are not equivalent.

Danoceras breve – Flower 1946: 420. ― Dzik 1984: 67, text-fig. 18.11.
Diagnosis
Danoceras with compressed elliptical to oval conch cross section (CHI = 1.3–1.4); mature body chamber with maximum conch height near its base with height of ca 42 mm; apical angle of the phragmocone ca 25°; conch surface, with distinct constriction near peristome and amphora-like apertural opening.
Material examined
ESTONIA • 1 spec.; Haapsalu holm; Adila Formation, Pirgu Regional Stage; GIT 426-988.
Type locality and horizon
Vestre Svartøy, Ringerike, Norway; Bønsnes Formation, late Katian.
Description
The specimen is a slightly deformed fragment of a phragmocone and the mature body chamber. The maximum conch height of the specimen (41 mm) is at the base of the body chamber. There, the conch width is 30 mm (CHI = 1.37). The preserved part of the body chamber is 27 mm long.
The phragmocone increases in conch height from 23 mm to 40 mm at a length of 38 mm (angle of expansion 25°). At the adoral end of the phragmocone, the chamber length is 6 mm (RCL = 0.15). Traces of a weak longitudinal striation are preserved on the surface of the internal cast of the phragmocone. The conch surface is not preserved. The conch is very slightly curved with a thin (ca 3 mm in diameter) siphuncle preserved near the conch margin at the convex side of the conch curvature.
Remarks
This specimen is very similar in dimensions and conch shape to the types of Danoceras breve and although details of the siphuncle are not examined, the thin marginal siphuncle is indicative of a species of Danoceras.
