description: During the early months of 2003, there was something of a buzz in monetary policy circles about the prospect of a move toward inflation targeting as a policy regime for the Federal Reserve. One leading manifestation was a prominent article in the Wall Street Journal on March 31 concerning the different points of view recently expressed by Fed Governors Ben Bernanke and Donald Kohn. Of course, there was little or no direct disputation; the WSJ article was based on substantial comments presented by Bernanke and Kohn at different conferences but released at about the same time. Kohn’s comments were delivered at a January 24-25 conference, sponsored by the National Bureau of Economic Research, at which he was the formal discussant of a paper by Marvin Goodfriend (2003). The specific item by Bernanke, mentioned in the WSJ article, is evidently his speech given at a March 25 conference of the National Association of Business Economists. Although there has not been direct disputation, there are significant differences of opinion expressed in the two Governors’ writings, as well as the paper by Goodfriend, differences that mirror important issues and call out for discussion.

description: Multi-band superconductivity is realized in a plethora of systems, from high-temperature superconductors to very diluted superconductors. While several properties of multi-band superconductors can be understood as straightforward generalizations of their single-band counterparts, recent works have unveiled rather unusual behaviors unique to the former case. In this regard, a regime that has received significant attention is that near a Lifshitz transition, in which one of the bands crosses the Fermi level. In this work, we investigate how impurity scattering $τ^{-1}$ affects the superconducting transition temperature $T_{c}$ across a Lifshitz transition, in the regime where intra-band pairing is dominant and inter-band pairing is subleading. This is accomplished by deriving analytic asymptotic expressions for $T_{c}$ and $\partial T_{c}/\partialτ^{-1}$ in a two-dimensional two-band system. When the inter-band pairing interaction is repulsive, we find that, despite the incipient nature of the band crossing the Fermi level, inter-band impurity scattering is extremely effective in breaking Cooper pairs, making $\partial T_{c}/\partialτ^{-1}$ quickly approach the limiting Abrikosov-Gor'kov value of the high-density regime. In contrast, when the inter-band pairing interaction is attractive, pair-breaking is much less efficient, affecting $T_{c}$ only mildly at the vicinity of the Lifshitz transition. The consequence of this general result is that the behavior of $T_{c}$ across a Lifshitz transition can be qualitatively changed in the presence of strong enough disorder: instead of displaying a sharp increase across the Lifshitz transition, as in the clean case, $T_{c}$ can actually display a maximum and be suppressed at the Lifshitz transition. These results shed new light on the non-trivial role of impurity scattering in multi-band superconductors.

description: We perform an analysis of two-body non leptonic decays of $B$ and $B_s$ mesons in the factorization approximation. We make use of the semileptonic decay amplitudes previously calculated on the basis of an effective lagrangian satisfying chiral and heavy quark symmetries and including spin 1 resonances. Exclusive semileptonic $D$-decay data are used as experimental input. Our results compare favorably with data, whenever they are available and indicate a positive value for the ratio of non leptonic coefficients $a_2/a_1$, similarly to previous studies.

description: With a goal toward deriving the physical conditions in external galaxies, we present a survey of the formaldehyde emission in a sample of starburst systems. By extending a technique used to derive the spatial density in star formation regions in our own Galaxy, we show how the relative intensity of the 1(10)-1(11) and 2(11)-2(12) K-doublet transitions of H2CO can provide an accurate densitometer for the active star formation environments found in starburst galaxies. Relying upon an assumed kinetic temperature and co-spatial emission and absorption from both H2CO transitions, our technique is applied to a sample of nineteen IR-bright galaxies which exhibit various forms of starburst activity. In the five galaxies of our sample where both H2CO transitions were detected we have derived spatial densities. We also use H2CO to estimate the dense gas mass in our starburst galaxy sample, finding similar mass estimates for the dense gas forming stars in these objects as derived using other dense gas tracers. A related trend can be seen when one compares L_IR to our derived n(H2) for the five galaxies within which we have derived spatial densities. Even though our number statistics are small, there appears to be a trend toward higher spatial density for galaxies with higher infrared luminosity. This is likely another representation of the L_IR-M_dense correlation.

In the molecular field approximation the Gibbs free-energy is derived, from which all magnetic thermodynamic properties can be self-consistently obtained.

Can the Axions of Standard--like Superstring Models Solve the Strong CP Problem?

description: We find that there are three axions in standard--like superstring models in the four dimensional free fermionic formulation. These axions are either harmful or very heavy. Therefore, they cannot solve the strong CP problem. We show that this is a general result in superstring models with chiral generations from the $Z_2$ twisted sectors which use a $Z_4$ twist.

description: Deep convolutional neural networks (CNNs) obtain outstanding results in tasks that require human-level understanding of data, like image or speech recognition. However, their computational load is significant, motivating the development of CNN-specialized accelerators. This work presents NEURAghe, a flexible and efficient hardware/software solution for the acceleration of CNNs on Zynq SoCs. NEURAghe leverages the synergistic usage of Zynq ARM cores and of a powerful and flexible Convolution-Specific Processor deployed on the reconfigurable logic. The Convolution-Specific Processor embeds both a convolution engine and a programmable soft core, releasing the ARM processors from most of the supervision duties and allowing the accelerator to be controlled by software at an ultra-fine granularity. This methodology opens the way for cooperative heterogeneous computing: while the accelerator takes care of the bulk of the CNN workload, the ARM cores can seamlessly execute hard-to-accelerate parts of the computational graph, taking advantage of the NEON vector engines to further speed up computation. Through the companion NeuDNN SW stack, NEURAghe supports end-to-end CNN-based classification with a peak performance of 169 Gops/s, and an energy efficiency of 17 Gops/W. Thanks to our heterogeneous computing model, our platform improves upon the state-of-the-art, achieving a frame rate of 5.5 fps on the end-to-end execution of VGG-16, and 6.6 fps on ResNet-18.

description: Cochrane (2007) has strongly questioned the basic economic logic of current monetary policy analysis, arguing that New Keynesian (NK) models imply rational expectations paths with explosive inflation that do not imply explosions in real variables relevant for transversality conditions. Consequently, the usual logic does not rule out solutions with explosive inflation. That result does not, however, justify negative conclusions about NK analysis, for a different criterion is logically satisfactory. It is that, to be plausible, a RE solution must satisfy the property of least-squares learnability. Adoption of this criterion serves to justify in principle the bulk of current mainstream analysis.

description: DANSS is a highly segmented 1~m${}^3$ plastic scintillator detector. Its 2500 one meter long scintillator strips have a Gd-loaded reflective cover. The DANSS detector is placed under an industrial 3.1~$\mathrm{GW_{th}}$ reactor of the Kalinin Nuclear Power Plant 350~km NW from Moscow. The distance to the core is varied on-line from 10.7~m to 12.7~m. The reactor building provides about 50~m water-equivalent shielding against the cosmic background. DANSS detects almost 5000 $\widetildeν_e$ per day at the closest position with the cosmic background less than 3$\%$. The inverse beta decay process is used to detect $\widetildeν_e$. Sterile neutrinos are searched for assuming the $4ν$ model (3 active and 1 sterile $ν$). The exclusion area in the $Δm_{14}^2,\sin^22θ_{14}$ plane is obtained using a ratio of positron energy spectra collected at different distances. Therefore results do not depend on the shape and normalization of the reactor $\widetildeν_e$ spectrum, as well as on the detector efficiency. Results are based on 966 thousand antineutrino events collected at 3 distances from the reactor core. The excluded area covers a wide range of the sterile neutrino parameters up to $\sin^22θ_{14}<0.01$ in the most sensitive region.

We also investigate a quantum particle described by the Klein-Gordon oscillator in the background space-time generated by a string. An important result obtained is that the non-inertial effects restrict the physical region of the space-time where the particle can be placed. In addition, we show that these potentials can form bound states for the relativistic wave equation equation in this kind of background.

description: We show in details that the all-orders genus expansion of the two-cut Hermitian cubic matrix model reproduces the perturbative expansion of the $H_1$ Argyres-Douglas theory coupled to the $Ω$ background. In the self-dual limit we use the Painlevé/gauge correspondence and we show that, after summing over all instanton sectors, the two-cut cubic matrix model computes the tau function of Painlevé II without taking any double scaling limit or adding any external fields. We decode such solution within the context of trans-series. Finally in the Nekrasov-Shatashvili limit we connect the $H_1$ and the $H_0$ Argyres-Douglas theories to the quantum mechanical models with cubic and double well potentials.

description: A microfabricated Fabry-Perot optical resonator has been used for atom detection and photon production with less than 1 atom on average in the cavity mode. Our cavity design combines the intrinsic scalability of microfabrication processes with direct coupling of the cavity field to single-mode optical waveguides or fibers. The presence of the atom is seen through changes in both the intensity and the noise characteristics of probe light reflected from the cavity input mirror. An excitation laser passing transversely through the cavity triggers photon emission into the cavity mode and hence into the single-mode fiber. These are first steps towards building an optical microcavity network on an atom chip for applications in quantum information processing.

Size of spectroscopic calibration samples for cosmic shear photometric redshifts

name: Bernstein, Gary
Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Weak gravitational lensing surveys using photometric redshifts can have their cosmological constraints severely degraded by errors in the photo-z scale. We explore the cosmological degradation vs the size of the spectroscopic survey required to calibrate the photo-z probability distribution. Previous work has assumed a simple Gaussian distribution of photo-z errors; here we describe a method for constraining an arbitrary parametric photo-z error model. As an example we allow the photo-z probability distribution to be the sum of $N_g$ Gaussians. To limit cosmological degradation to a fixed level, photo-z models with multiple Gaussians require up to 5 times larger calibration sample than one would estimate from assuming a single-Gaussian model. This degradation saturates at $N_g\approx 4$. Assuming a single Gaussian when the photo-z distribution has multiple parameters underestimates cosmological parameter uncertainties by up to 35%. The size of required calibration sample also depends upon the shape of the fiducial distribution, even when the RMS photo-z error is held fixed. The required calibration sample size varies up to a factor of 40 among the fiducial models studied, but this is reduced to a factor of a few if the photo-z parameters are forced to be slowly varying with redshift. Finally we show that the size of the required calibration sample can be substantially reduced by optimizing its redshift distribution. We hope this study will help stimulate work on better understanding of photo-z errors.

description: Integrated entangled photon pair source is an essential resource for both fundamental investigations and practical applications of quantum information science. Currently there have been several types of entanglement, among which the transverse-mode entanglement is becoming attractive because of its unique advantages. Here, we report an on-chip transverse-mode entangled photon pair source via the spontaneous four-wave mixing processes in a multimode silicon waveguide. Transverse-mode photon pairs are verified over multiple frequency channels within a bandwidth of $\sim$2~THz, and a maximally entangled Bell state is also produced with a net fidelity of $0.96\pm0.01$. Our entangled photon pair source is the key element for quantum photonics based on transverse-mode, and also has the possibility to extend to higher-dimensional Hilbert space. Furthermore, the transverse-mode entanglement can be converted coherently to path and polarization entanglement, which paves the way to realizing highly complex quantum photonic circuits with multiple degrees of freedom.

description: We explain how nonperturbative effects can be systematically included when constructing an effective field theory. We concentrate in particular on the matching calculation, by which a low energy theory without a heavy particle degree of freedom is matched onto the full theory. The matching calculation requires some new formalism, because for a large class of theories, instantons occur in a continuous range of scales from far below the mass of the heavy particle to far above. We show how the complete IR finiteness of the usual matching formalism arises in this new context. As an example, we formally integrate out a heavy quark in QCD. %%%% Includes 14 PiCTeX figures. %%%%

title: Contextualizing Practical Knowledge in Early Modern Europe
Creators: name: Leemans, Annemie Daniel Gerda
Publisher: name: University of Kent
Year: 2016

description: The overarching topic of this dissertation is practical knowledge in early modern Europe. Practical knowledge is the know-how people have in order to make something, do something or obtain something. Textually speaking, this knowledge profiles itself as a prescription, recipe, secret, or formula. The areas of interest of practical knowledge are very wide from kitchen wisdom to medical panaceas. The main aim of this interdisciplinary study is to contextualize practical knowledge. By 'contextualizing' I mean studying different topics that are intrinsically intertwined with the subject. In this PhD dissertation the 1) origin or creation, 2) transmission or dissemination, and 3) use or consumption are key subjects for understanding the place of practical knowledge in early modern European society. These three topics are reflected in the six chapters. The first part, containing the first three chapters, deals with practical knowledge in general and the second part, containing the last three chapters, deals with a case study of a book called A Very Proper Treatise (1573). The first chapter of the first part, which is an introduction to the whole thesis, contains the historiography and theory about the subject concerning practical knowledge production and status. The second chapter studies transmission dynamics of practical knowledge, making use of the rhizome metaphor of Deleuze and Guattari and examining transmission dynamics in specialized environments, such as workshops and laboratories. In the third chapter of Part I, I develop the concept of mediators of practical knowledge, arguing that some people, either literary writers or practitioners, used the printing medium to earn in their living. As a consequence they are responsible for a major dissemination of practical knowledge. Part II of this PhD dissertation is conceived as a microapproach. In this part the study of the early English print A Very Proper Treatise (1573) finds its legitimate place. This Treatise about limning, or painting in books, will be examined through the same three lenses used in Part I: creation, dissemination, and consumption. In the first chapter the origin of the text of the book is examined. The following chapter examines the making or origin of the material book, where I argue that it is a printer's compilation. Finally, the consumption and consumers of the book will be studied in the third and last chapter.

description: An unparallelled record of.growth and achievement has been established by the American economy in the past hundred years. Through peace and war, through prosperity and depression, through inflation and deflation, the economy has moved ahead at an average rate of 3.5 per cent a year. At this rate, the production of real goods and services doubles every twenty years; every decade American industry turns out fifty per cent more than in the previous ten years. No other nation has matched, or even approached, this long-term record. Some countries have had exceptional high growth rates for short periods, and some have maintained these rates for a decade or more. West Germany and Japan provide examples of the enormous changes in living standards that become available within a generation by sustained growth at the rate of 10% a year or more. These achievements, impressive as they are, are brought into perspective when we compare the German and Japanese economies to the-U. S. economy and realize that at current rates of real growth in the three countries, we add the equivalent of Germany's or Japan's total output to our own every few years.

description: We investigate theoretically the spectrum of a graphene-like sample (honeycomb lattice) subjected to a perpendicular magnetic field and irradiated by circularly polarized light. This system is studied using the Floquet formalism, and the resulting Hofstadter spectrum is analyzed for different regimes of the driving frequency. For lower frequencies, resonances of various copies of the spectrum lead to intricate formations of topological gaps. In the Landau-level regime, new wing-like gaps emerge upon reducing the driving frequency, thus revealing the possibility of dynamically tuning the formation of the Hofstadter butterfly. In this regime, an effective model may be analytically derived, which allows us to retrace the energy levels that exhibit avoided crossings and ultimately lead to gap structures with a wing-like shape. At high frequencies, we find that gaps open for various fluxes at $E=0$, and upon increasing the amplitude of the driving, gaps also close and reopen at other energies. The topological invariants of these gaps are calculated and the resulting spectrum is elucidated. We suggest opportunities for experimental realization and discuss similarities with Landau-level structures in non-driven systems.

description: Using a cosmological N-Body simulation and a sample of re-simulated cluster-like haloes, we study the mass loss rates of dark matter subhaloes, and interpret the mass function of subhaloes at redshift zero in terms of the evolution of the mass function of systems accreted by the main halo progenitor. When expressed in terms of the ratio between the mass of the subhalo at the time of accretion and the present day host mass the unevolved subhalo mass function is found to be universal. However, the subhalo mass function at redshift zero clearly depends on $M_0$, in that more massive host haloes host more subhaloes. To relate the unevolved and evolved subhalo mass functions, we measure the subhalo mass loss rate as a function of host mass and redshift. We find that the average, specific mass loss rate of dark matter subhaloes depends mainly on redshift. These results suggest a pleasingly simple picture for the evolution and mass dependence of the evolved subhalo mass function. Less massive host haloes accrete their subhaloes earlier, which are thus subjected to mass loss for a longer time. In addition, their subhaloes are typically accreted by denser hosts, which causes an additional boost of the mass loss rate. To test the self-consistency of this picture, we use a merger trees constructed using the extended Press-Schechter formalism, and evolve the subhalo populations using the average mass loss rates obtained from our simulations, finding the subhalo mass functions to be in good agreement with the simulations.

description: In this talk, we present a model based on SU(5)x(d)T which successfully gives rise to near tri-bimaximal leptonic mixing as well as realistic CKM matrix elements for the quarks. The Georgi-Jarlskog relations for three generations are also obtained. Due to the (d)T transformation property of the matter fields, the b-quark mass can be generated only when the (d)T symmetry is broken, giving a dynamical origin for the hierarchy between m_b and m_t. There are only nine operators allowed in the Yukawa sector up to at least mass dimension seven due to an additional Z12 x Z12' symmetry, which also forbids, up to some high orders, operators that lead to proton decay. The resulting model has a total of nine parameters in the charged fermion and neutrino sectors, and hence is very predictive. In addition to the prediction for theta13 ~ theta_c/3sqrt{2}, the model gives rise to a sum rule, tan^2(theta_{solar}) ~ tan^2(theta_{solar,TBM}) - 1/2*theta_c*cos(beta), which is a consequence of the Georgi-Jarlskog relations in the quark sector. This deviation could account for the difference between the experimental best fit value for the solar mixing angle and the value predicted by the tri-bimaximal mixing matrix.

description: Temperature equilibration of hydrogen is studied for conditions relevant to inertial confinement fusion. New molecular-dynamics simulations and results from quantum many-body theory are compared with Landau-Spitzer (LS) predictions for temperatures T from 50 eV to 5000 eV, and densities with Wigner-Seitz radii r_s = 1.0 and 0.5. The relaxation is slower than the LS result, even for temperatures in the keV range, but converges to agreement in the high-T limit.

description: Quantum theory shares with classical probability theory many important properties. I show that this common core regards at least the following six areas, and I provide details on each of these: the logic of propositions, symmetry, probabilities, composition of systems, state preparation and reductionism. The essential distinction between classical and quantum theory, on the other hand, is shown to be joint decidability versus smoothness; for the latter in particular I supply ample explanation and motivation. Finally, I argue that beyond quantum theory there are no other generalisations of classical probability theory that are relevant to physics.

description: Brazil's anti-inflation policy has frequently confused symptoms with causes and relied on one-time stop gaps. At times, these measures were based on the belief that inflation is an inertial process that can be stopped (or slowed) permanently by breaking the momentum. Policies based on this belief such as freezing wages and prices, changing the currency unit or freezing part of the stock of financial assets have failed to stop inflation. However, the last of these measures-the Collor plan-prevented inflation from becoming hyperinflation in 1990.

description: The All-Sky Automated Survey for Supernovae (ASAS-SN) is the first optical survey to routinely monitor the whole sky with a cadence of $\sim2-3$ days down to V$\lesssim17$ mag. ASAS-SN has monitored the whole sky since 2014, collecting $\sim100-500$ epochs of observations per field. The V-band light curves for candidate variables identified during the search for supernovae are classified using a random forest classifier and visually verified. We present a catalog of 66,179 bright, new variable stars discovered during our search for supernovae, including 27,479 periodic variables and 38,700 irregular variables. V-band light curves for the ASAS-SN variables are available through the ASAS-SN variable stars database (https://asas-sn.osu.edu/variables). The database will begin to include the light curves of known variable stars in the near future along with the results for a systematic, all-sky variability survey.

description: We show that the discrete anomaly constraints governing popular non-Abelian symmetries of use in (e.g.) flavoured, supersymmetric, and dark matter model building typically subdivide into two classes differentiated by the simple restrictions they impose on the number of fields transforming under certain irreducible representations of the relevant groups. These constraints lead us both to generic conclusions for common Beyond-the-Standard-Model constructions (including rather powerful statements for Grand Unified theories) as well as to simplified formulae that can be rapidly applied to determine whether a given field and symmetry content suffers from gauge and gravitational anomalies.

description: Is inflation dead? Or is it just hiding? Many Wall Street economists point to the 2.7% increase in consumer prices last year and project about the same for 1994 - 3% or less. Standard opinion sees little risk of higher inflation. Although bond and mortgage markets have retreated from the low rates of last fall, these markets, too, show few signs of rising inflation. Even some usually cautious Federal Reserve Governors have made soothing and optimistic sounds recently.

description: In this paper, we study the MUltiple SIgnal Classification (MUSIC) algorithm often used to image small targets when multiple measurement vectors are available. We show that this algorithm may be used when the imaging problem can be cast as a linear system that admits a special factorization. We discuss several active array imaging configurations where this factorization is exact, as well as other configurations where the factorization only holds approximately and, hence, the results provided by MUSIC deteriorate. We give special attention to the most general setting where an active array with an arbitrary number of transmitters and receivers uses signals of multiple frequencies to image the targets. This setting provides all the possible diversity of information that can be obtained from the illuminations. We give a theorem that shows that MUSIC is robust with respect to additive noise provided that the targets are well separated. The theorem also shows the relevance of using appropriate sets of controlled parameters, such as excitations, to form the images with MUSIC robustly. We present numerical experiments that support our theoretical results.
title: Numerical simulation of drop array impingement onto a superheated wall

description: Spray cooling is a very efficient method for thermal management of high-performance electronics. The performance of spray cooling is determined by the fluid dynamics and the heat transport when a single drop or multiple drops hit the superheated wall. To understand this process, we numerically study the generic situation of simultaneous impingement of periodic drop arrays onto a superheated wall. We study three different cases in which the distance between the drops varies. The refrigerant used is perfluorohexane (FC-72) in a pure vapor atmosphere under saturation conditions. Drops impinge at moderate Reynolds and Weber numbers, where no splashing occurs during single drop impingement. The wall temperature is above the saturation temperature of the fluid but below the onset of nucleate boiling. Simulations are performed using the OpenFOAM software library, taking into account a dynamic contact angle, evaporation and conjugate heat transfer. We show that the coalescence of more than two drops results in the formation of a liquid jet. A small distance between the drops results in the formation of a thin liquid film while a large distance results in small drops sitting on the wall. In the latter case, the largest amount of heat is transferred, but the occurrence of dry spots is undesirable for cooling applications. The results contribute to a better understanding of spray cooling and provide a perspective for efficient spray cooling.

description: Cavity polaritons have been shown these last years to exhibit a rich variety of non-linear behaviors which could be used in new polariton based devices. Operation in the strong coupling regime under electrical injection remains a key step toward a practical polariton device. We report here on the realization of a polariton based light emitting diode using a GaAs microcavity with doped Bragg mirrors. Both photocurrent and electroluminescence spectra are governed by cavity polaritons up to 100 K.

Uniqueness of Equilibrium with Sufficiently Small Strains in Finite Elasticity

description: The uniqueness of equilibrium for a compressible, hyperelastic body subject to dead-load boundary conditions is considered. It is shown, for both the displacement and mixed problems, that there cannot be two solutions of the equilibrium equations of Finite (Nonlinear) Elasticity whose nonlinear strains are uniformly close to each other. This result is analogous to the result of Fritz John (Comm. Pure Appl. Math. 25, 617-634, 1972) who proved that, for the displacement problem, there is a most one equilibrium solution with uniformly small strains. The proof in this manuscript utilizes Geometric Rigidity; a new straightforward extension of the Fefferman-Stein inequality to bounded domains; and, an appropriate adaptation, for Elasticity, of a result from the Calculus of Variations. Specifically, it is herein shown that the uniform positivity of the second variation of the energy at an equilibrium solution implies that this mapping is a local minimizer of the energy among deformations whose gradient is sufficiently close, in $BMO\cap\, L^1$, to the gradient of the equilibrium solution.

Inferring Competitor Pricing with Incomplete Information

description: We study how business customers make multi-product purchase decisions and how the distributors who sell those products can make inferences about their demand functions with incomplete information. The problem is that distributors rarely observe a competitor's price directly, and must infer competitor response indirectly from their own observations about customer purchases. In this research we propose that customers make their product orders by minimizing procurement costs. Using the first order conditions from this optimization problem we characterize the regions of the parameter space where consumers buy from each distributor. We use these conditions to estimate a model of purchase behavior that enables us to identify the likelihood of each consumer buying from the competitor versus a direct change in consumption patterns. Our proposed model is applied to a wholesale food distributor and we find widespread heterogeneity in purchase patterns. The empirical results shed light on the competitive elements of customer demand that cannot be studied with traditional reduced form response models. For example, we found that some costumers satisfy most of their requirement from one of their distributors, while others consistently split their demands across suppliers. Also, we found that price sensitivity of customers making most of their purchases with the focal supplier are less affected by the volume of purchases in previous periods. We expect this result to provide valuable information for vendors to negotiate prices with the customers. It allows the distributor to make efficient inferences about competitors in those occasions when competitor price is not directly observed.
