description: Recent progress in understanding the electronic band topology and emergent topological properties encourage us to reconsider the band structure of well-known materials including elemental substances. Controlling such a band topology by external field is of particular interest from both fundamental and technological view point. Here we report the pressure-induced topological phase transition from a semiconductor to a Weyl semimetal in elemental tellurium probed by transport measurements. Pressure variation of the periods of Shubnikov-de Haas oscillations, as well as oscillations phases, shows an anomaly around the pressure theoretically predicted for topological phase transition. This behavior can be well understood by the pressure-induced band deformation and resultant band crossing effect. Moreover, effective cyclotron mass is reduced toward the critical pressure, potentially reflecting the emergence of massless linear dispersion. The present result paves the way for studying the electronic band topology in well-known compounds and topological phase transition by the external field.

description: In this work, we develop an extended uniform potential (UP) model for a membrane nanopore by including two different charging mechanisms of the pore walls, namely by electronic charge and by chemical charge. These two charging mechanisms will generally occur in polymeric membranes with conducting agents, or membranes made of conducting materials like carbon nanotubes with surface ionizable groups. The electronic charge redistributes along the pore in response to the gradient of electric potential in the pore, while the chemical charge depends on the local pH via a Langmuir-type isotherm. The extended UP model shows good agreement with experimental data for membrane potential measured at zero current condition. When both types of charge are present, the ratio of the electronic charge to the chemical charge can be characterized by the dimensionless number of surface groups and the dimensionless capacitance of the dielectric Stern layer. The performance of the membrane pore in converting osmotic energy from a salt concentration difference into electrical power can be improved by tuning the electronic charge.

description: We present evidence of 6.7 GHz methanol (CH3OH)~and 4.8 GHz formaldehyde (H2CO) absorption towards the Galactic Center (GC) point-source `N3'. Both absorption features are unresolved and spatially aligned with N3. The 6.7 GHz CH3OH contains a single velocity component (centered at ~10 km/s) while the 4.8 GHz H2CO shows two velocity components (centered at ~-3 and +8 km/s). We find that the velocity of these absorption components are similar to that of emission lines from other molecules (e.g., SiO and H3CN) detected toward this compact-source (-13 to +25 km/s; `N3 cloud'). The detection of these absorption features is a firm indication that some of the molecular gas in the N3 molecular cloud is on the near-side of the continuum source. Analysis of the CH3OH absorption kinematics shows a relatively large velocity dispersion (3.8 km/s) for the size scale of this feature (<0.1'', <0.01 pc at the GC; Ludovici et al. 2016), when compared with other similar size GC clouds in the Larson linewidth-size relationship. Further, this linewidth is closer to velocity dispersion measurements for size scales of 1.3 pc, which is roughly the width of the N3 cloud (25''; 1.0 pc). We argue that this relatively broad linewidth, over a small cross-sectional area, is due to turbulence through the depth of the cloud, where the cloud has a presumed line-of-sight thickness of ~1 pc.

description: We investigate the physical mechanisms that shape the luminosity function. Beginning with the mass function of dark matter halos, we show how gas cooling, photoionization, feedback, merging and thermal conduction affect the shape of the luminosity function. We consider three processes whereby supernovae can affect the forming galaxy: (1) reheating of disk gas to the halo temperature; (2) expansion of the diffuse halo gas; (3) expulsion of cold disk gas from the halo. While feedback of form (1) is able to flatten the faint end of the luminosity function, this alone does not produce the sharp cut-off observed at large luminosities. Feedback of form (2) is also unable to solve this problem. The relative paucity of very bright galaxies can only be explained if cooling in massive halos is strongly suppressed. Conduction is a promising mechanism, but an uncomfortably high efficiency is required to suppress cooling to the desired level. If, instead, superwinds are responsible for the lack of bright galaxies, then the total energy budget required to obtain a good match to the galaxy luminosity function greatly exceeds the energy available from supernova explosions. The mechanism is only viable if the formation of central supermassive black holes play a crucial role in limiting the amount of stars that form in the host galaxy. (abridged)

description: The debate around the healthfulness of food choices for low-income households is still a relevant point of contention for policymakers as they aim to provide tools to incentivize consumption of healthier foods in different ways. Using fluid milk as a case study, and one year of household- level weekly milk purchases data in the Northeastern U.S., we assess the demand for milk of households with income levels above and below poverty, across fat content and packaging size. We find estimated own-price elasticities differing little across samples of households: even in cases where differences emerge, the estimated values, along with price differences experienced by purchasing households do not seem to justify the different purchasing patterns of the two household groups. Household characteristics however show differences in impacting the demand of milk across households with different income levels.

description: The main objective of this study was to analyze the effect of advertising on social welfare in a perfectly competitive market where the level of advertising is chosen by a social planner. The theoretical model revealed that social planner sponsored advertising that increases the equilibrium price of the advertised good can increase society’s welfare if the effect of advertising in consumers’ utility is higher than the consumer welfare reducing price effect (producer welfare is increased by the same amount as the reduction in consumer welfare). The empirical illustration focuses on the U.S. state of South Carolina “buy local” food products campaign. The findings suggest that this government sponsored advertising campaign increases total welfare.
Open and Closed Strings from Unstable D-branes

description: The tachyon effective field theory describing the dynamics of a non-BPS D-$p$-brane has electric flux tube solutions where the electric field is at its critical value and the tachyon is at its vacuum. It has been suggested that these solutions have the interpretation of fundamental strings. We show that in order that an electric flux tube can `end' on a kink solution representing a BPS D-$(p-1)$-brane, the electric flux must be embedded in a tubular region inside which the tachyon is finite rather than at its vacuum where it is infinite. Energetic consideration then forces the transverse `area' of this tube to vanish. We suggest a possible interpretation of the original electric flux tube solutions around the tachyon vacuum as well as of tachyon matter as system of closed strings at density far above the Hagedorn density.

description: The book is the culmination of research conducted as part of a research project financed by the Polish National Science Centre. The first thread of this research concerns the functioning of local government financial institutions in Poland and the European Union. However, the second thread concerns the preparation of basic assumptions for the legal regulation of the system of Polish depository and credit institutions (i.e. credit institutions, according to the European Union nomenclature), which are controlled by Polish local government units. In practice, there are two types of local government financial institutions in the European Union: credit institutions and credit guarantee funds. In Poland, of these two types of local government financial institutions, there are local government guarantee funds and loan funds created by voivodships. However, there are no local government depository and credit institutions on the Polish financial market at all.

description: In many resource management problems, the starting point is one involving a large number of users with imprecisely defined rights and an aggregate rate of resource use that is environmentally unsustainable. One possible policy response is to make formal or informal contracts with users, under which users receive current benefits in return for a commitment to forgo usage rights in future. If users have high discount rates, this response may permit a substantial reduction in resource use over time at relatively low cost. In this paper, this issue is explored with specific reference to the Murray-Darling River System

description: Bioelectrochemical systems are electrochemical cells that rely on conductive biofilms covering an electrode. We consider the example of a microbial fuel cell, and we derive a dynamic model of ion transport, biochemical reactions and electron transport inside such a biofilm. After validating the model against data, we evaluate model output to obtain an understanding of the transport of ions and electrons through a current-producing biofilm. For a system fed with a typical wastewater stream containing organic molecules and producing 5 A/m$^{2}$, our model predicts that transport of the organic molecules is not a limiting factor. However, the pH deep within the biofilm drops significantly, which can inhibit current production of such biofilms. Our results suggest that the electronic conductivity of the biofilm does not limit charge transport significantly, even for a biofilm as thick as 100 $μ\mathrm{m}$. Our study provides an example of how physics-based modelling helps to understand complex coupled processes in bioelectrochemical systems.

It turns out that the deviations from this idealized situation due to the unavoidable orbital injection errors would make impossible the measurement of the gravitomagnetic voltage of interest.

description: The relative merits of different property right systems to allocate water among different extractive uses where variability of supply is important are evaluated. Three systems of property rights are considered. In the first, variable supply is dealt with through the use of water rights defined as shares of the total quantity available. In the second, there are two types of water rights, one for water with a high security of supply and the other a low-security right for the residual supply. The third is a system of state-contingent claims. With zero transaction costs, all systems are efficient. In the realistic situation where transaction costs matter, the state-contingent claims system is globally optimal, and the system with high-security and low-security rights is preferable to the system with share allocations.

description: In this work we aim at addressing the still open question about the nature of Narrow-Line Seyfert 1 (NLS1) galaxies: are they really active nuclei with lower mass Black-Holes (BHs) than Seyfert 1 (S1) and quasars? Our approach is based on the recently discovered physical connections between nuclear supermassive BHs and their hosting spheroids (spiral bulges or ellipticals). In particular we compare BH masses of NLS1s and S1s analyzing the properties of their hosts by means of spectroscopic and photometric data in the optical wavelength domain. We find that NLS1s fill the low BH mass and bulge luminosity values of the BH mass - bulge magnitude relation, a result strongly suggesting that NLS1s are active nuclei where less massive BHs are hosted by less massive bulges. The correlation is good with a relatively small scatter fitting simultaneously NLS1s, S1s and quasars. On the other hand, NLS1s seem to share the same stellar velocity dispersion range of S1s in the BH mass - stellar velocity dispersion relation, indicating that NLS1s have a smaller BH/bulge mass ratio than S1s. These two conflicting results support in any case the idea that NLS1s could be young S1s. Finally we do not confirm the significantly non linear BH--bulge relation claimed by some authors.

description: We apply the weak formalism on the Boussinesq equations, to characterize scaling properties of the mean and the standard deviation of the potential, kinetic and viscous energy flux in very high resolution numerical simulations. The local Bolgiano-Oboukhov length $L_{BO}$ is investigated and it is found that its value may change of an order of magnitude through the domain, in agreement with previous results. We investigate the scale-by-scale averaged terms of the weak equations, which are a generalization of the Karman-Howarth-Monin and Yaglom equations. We have not found the classical Bolgiano-Oboukhov picture, but evidence of a mixture of Bolgiano-Oboukhov and Kolmogorov scalings. In particular, all the terms are compatible with a Bolgiano-Oboukhov local Hölder exponent for the temperature and a Kolmogorov 41 for the velocity. This behavior may be related to anisotropy and to the strong heterogeneity of the convective flow, reflected in the wide distribution of Bolgiano-Oboukhov local scales. The scale-by-scale analysis allows us also to compare the theoretical Bolgiano-Oboukhov length $L_{BO}$ computed from its definition with that empirically extracted through scalings obtained from weak analysis. The key result of the work is to show that the analysis of local weak formulation of the problem is powerful to characterize the fluctuation properties.

Ordinal, nonlinear context dependence

description: Prospect theory [KT79] and its more recent formalizations [KR06, KR07] prescribe "nonlinear" reference-dependence. The same may be said of other forms of context-dependence such as status quo bias [MO05]. Even in settings where there is a strong case for linear context-dependence such as Gilboa and Schmeidler's theory of case-based decisions, nonlinearity is typical in the absence of "diversity of preference". Furthermore, the hope of providing an axiomatic foundation for neuroscientific models of decision making, where context is interpreted as a physical state or "connectome" suggest a general, ordinal axiomatization of nonlinear context-dependence is called for. As with traditional, "context-free" models of ordinal utility (eg. Debreu [Deb54]), the issue of continuity is central: precise, yet simple and intuitive, conditions on the set of contexts are needed if preferences have a representation that is continuous across contexts. The continuity condition I employ is the obvious choice and is a generalisation of [GS03a]. There are interesting connections with literature on jointly continuous utility [Lev83, CCM09]. Finally, a promising feature of the present approach is it that may be used to axiomatise payoffs associated with discontinuous games (such as Bertrand oligopoly).
Riesz bases of reproducing kernels in small Fock spaces

description: We give a complete characterization of Riesz bases of normalized reproducing kernels in the small Fock spaces $\mathcal{F}^2_φ$, the spaces of entire functions $f$ such that $f\mathrm{e}^{-φ} \in L^{2}(\mathbb{C})$, where $φ(z)= (\log^+|z|)^{β+1}$, $0< β\leq 1$.The first results in this direction are due to Borichev-Lyubarskii who showed that $φ$ with $β=1$ is the largest weight for which the corresponding Fock space admits Riesz bases of reproducing kernels. Later, such bases were characterized by Baranov-Dumont-Hartman-Kellay in the case when $β=1$. The present paper answers a question in Baranov et al. by extending their results for all parameters $β\in (0,1)$. Our results are analogous to those obtained for the case $β=1$ and those proved for Riesz bases of complex exponentials for the Paley-Wiener spaces. We also obtain a description of complete interpolating sequences in small Fock spaces with corresponding uniform norm.

description: This paper develops a model of traffic stops and subsequent searches in which police officers use information about the race of drivers to maximize a well defined objective. The model provides a behavioral foundation absent from Grogger and Ridgeway’s (2006) elegantly simple test and, by incorporating searches, adds two complementary tests. Using data collected during 2002 by the Minneapolis Police Department, the tests rule out (1) statistical discrimination, (2) taste-based discrimination by optimizing police officers, and (3) statistical discrimination with cognitive limitations. The pattern of results is consistent with implicit discrimination.

description: Concordance invariants of knots are derived from the instanton homology groups with local coefficients, as introduced in earlier work of the authors. These concordance invariants include a 1-parameter family of homomorphisms $f_{r}$, from the knot concordance group to the reals. Prima facie, these concordance invariants have the potential to provide independent bounds on the genus and number of double points for immersed surfaces with boundary a given knot.

description: Previous research has found that, after controlling for test scores, measured black-white wage gaps are small but unemployment gaps remain large. This paper complements this previous research by examining the incidence of employer-provided benefits from the same premarket perspective. However, marriage rates differ substantially by race, and the possibility of health-insurance coverage through a spouse’s employer therefore distorts how the distribution of benefits available in the market to an individual is expressed in the distribution of benefits received. Two imputation strategies are used to address this complication. The evidence suggests that benefit availability gaps are small.

description: Large-scale polarization of the cosmic microwave background measured by the WMAP satellite requires a mean optical depth to Thomson scattering, tau_e ~ 0.17. The reionization of the universe must therefore have begun at relatively high redshift. We have studied the reionization process using supercomputer simulations of a large and representative region of a universe which has cosmological parameters consistent with the WMAP results. Our simulations follow both the radiative transfer of ionizing photons and the formation and evolution of the galaxy population which produces them. A previously published model with a standard stellar IMF, with a moderate photon escape fraction from galaxies and with ionizing photon production as expected for zero metallicity stars produces tau_e = 0.104, which is within 1.0 to 1.5-sigma of the ``best'' WMAP value. Values up to 0.16 can be produced by taking larger escape fractions or a top heavy IMF. The data do not require a separate populations of ``miniquasars'' or of stars forming in objects with total masses below 10^9 M_sun. Reconciling such early reionization with the observed Gunn-Peterson troughs in z>6 quasars may be challenging. Possible resolutions of this problem are discussed.

A ring of instantons inducing a monopole loop

description: We consider the superposition of infinitely many instantons on a circle in R^4. The construction yields a self-dual solution of the Yang-Mills equations with action density concentrated on the ring. We show that this configuration is reducible in which case magnetic charge can be defined in a gauge invariant way. Indeed, we find a unit charge monopole (worldline) on the ring. This is an analytic example of the correlation between monopoles and action/topological density, however with infinite action. We show that both the Maximal Abelian Gauge and the Laplacian Abelian Gauge detect the monopole, while the Polyakov gauge does not. We discuss the implications of this configuration.

description: Record-high U.S. strawberry production in 1993 and another large crop anticipated in 1994 continue the growth trend that began in the 1970's. California produced nearly 80 percent of the U.S. crop on less than half of the strawberry acreage due to higher output per acre than other States. Grower and retail prices for fresh strawberries usually follow strong seasonal patterns and are below average in April, May, and June. Retail prices for fresh strawberries have kept pace with inflation since 1980, while grower prices have not. Americans are eating more strawberries grown in the United States, and per capita consumption has grown from 3 to 5 pounds since 1970.
Resources of nonlinear cavity magnonics for quantum information

description: We theoretically explore nonlinearities of ferromagnets in microwave cavities in the classical and quantum regimes, and assess the resources for quantum information, i.e. fluctuation squeezing and bipartite entanglement. The (semi-)classical analysis of the anharmonic oscillator (Duffing) model for the Kittel mode when including all other magnon modes, reveals chaotic and limit-cycle phases that do not survive in quantum calculations. However, magnons with nonzero wavenumbers that are driven by the Suhl instability of the Kittel mode, form a genuine limit cycle. We subsequently compute bounds for the distillable entanglement, as well as entanglement of formation for the bipartite configurations of the mixed magnon modes. The distillable entanglement of bipartite states accessible from a covariance matrix vanishes, but can be recovered by injection locking. The predicted magnon entanglement can be experimentally tested with yttrium iron garnet samples under realistic conditions.

"Squashed Entanglement" - An Additive Entanglement Measure

name: Winter, Andreas
Publisher: name: arXiv
Year: 2003
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: In this paper, we present a new entanglement monotone for bipartite quantum states. Its definition is inspired by the so-called intrinsic information of classical cryptography and is given by the halved minimum quantum conditional mutual information over all tripartite state extensions. We derive certain properties of the new measure which we call "squashed entanglement": it is a lower bound on entanglement of formation and an upper bound on distillable entanglement. Furthermore, it is convex, additive on tensor products, and superadditive in general. Continuity in the state is the only property of our entanglement measure which we cannot provide a proof for. We present some evidence, however, that our quantity has this property, the strongest indication being a conjectured Fannes type inequality for the conditional von Neumann entropy. This inequality is proved in the classical case.

Order ${\bf 1/N^3}$ corrections to the conformal anomaly of the (2,0) theory in six dimensions

description: Using Supergravity on $AdS_7\times S^4$ we calculate the bulk one-loop contribution to the conformal anomaly of the (2,0) theory describing $N$ coincident M5 branes. When this is added to the tree-level result, and an additional subleading order contribution calculated by Tseytlin, it gives an expression for the anomaly that interpolates correctly between the large $N$ theory and the free (2,0) tensor theory corresponding to N=1. Thus we can argue that we have identified the exact $N$-dependence of the anomaly, which may have a simple protected form valid away from the large $N$ limit.

description: For one qubit systems, we present a short, elementary argument characterizing unital quantum operators in terms of their action on Bloch vectors. We then show how our approach generalizes to multi-qubit systems, obtaining inequalities that govern when a ``diagonal'' superoperator on the Bloch region is a quantum operator. These inequalities are the n-qubit analogue of the Algoet-Fujiwara conditions. Our work is facilitated by an analysis of operator-sum decompositions in which negative summands are allowed.

description: We present a heterodyne terahertz spectrometry platform based on plasmonic photomixing, which enables the resolution of narrow spectral signatures of gases over a broad terahertz frequency range. This plasmonic heterodyne spectrometer replaces the terahertz mixer and local oscillator of conventional heterodyne spectrometers with a plasmonic photomixer and a heterodyning optical pump beam, respectively. The heterodyning optical pump beam is formed by two continuous-wave, wavelength-tunable lasers with a broadly tunable terahertz beat frequency. This broadly tunable terahertz beat frequency enables spectrometry over a broad bandwidth, which is not restricted by the bandwidth limitations of conventional terahertz mixers and local oscillators. We use this plasmonic heterodyne spectrometry platform to resolve the spectral signatures of ammonia over a 1-5 THz frequency range.

description: This report presents historical data on food consumption, prices, expenditures, and U.S. income and population. In 1993, Americans consumed, on average, 61 pounds more of commercially grown vegetables than in 1970; 54 pounds more of grain products; 48 pounds more of fruit; 23 pounds more of added sugars; 12 pounds more of added fats and oils; 12 pounds more of cheese; 11 pounds more of total red meat, poultry, and fish (boneless, trimmed equivalent); 5 gallons more of beer; 76 fewer eggs; 7 gallons less of coffee; and 6 gallons less of milk. Food prices, as measured by the Consumer Price Index (CPI) increased 2.2 percent in 1993. This increase was less than the overall increase in the CPI for the third consecutive year. ~Americans spent $617 billion for food in 1993 and another $86 billion for alcoholic beverages. Away-from-homemeals and snacks captured 46 percent of the food dollar in 1993, up from 39 percent in 1980 and 34 percent in 1970. The percentage of disposable personal income spent on food declined from 13.9 percent in 1970 to 11.2 percent in 1993.

description: We find subtle deviations from power law behaviour in the number of crimes committed by individuals, analysing the two main criminology databases which track this behaviour, the Pittsburgh Young Offenders survey and the Cambridge UK Study in Delinquent Development. The description of the data when the number of boys committing or reporting zero crimes are excluded is different from that when they are included. The crucial step in the criminal progress of an individual appears to be committing the first act. Once this is done, the number of criminal acts committed by an individual can take place on all scales.
