description: We study the mean field dilute model of a ferromagnet. We find and prove an expression for the free energy density at high temperature, and at temperature zero. We find the critical line of the model, separating the phase with zero magnetization from the phase with symmetry breaking. We also compute exactly the entropy at temperature zero, which is strictly positive. The physical behavior at temperature zero is very interesting and related to infinite dimensional percolation, and suggests possible behaviors at generic low temperatures. Lastly, we provide a complete solution for the annealed model. Our results hold both for the Poisson and the Bernoulli versions of the model.

Publisher: name: Kentucky Transportation Center, University of Kentucky
Year: 1951
Subjects: subject: Transportation Engineering

description: Early in the 1950 construction season the Division of Design requested that the Research Division observe some new methods and materials that were being used in bituminous construction. The projects chosen in most cases represented several of the type throughout the state. There were some instances though where the procedure or material was used in only one project.  The purpose of this investigation was to determine the effectiveness of the materials and the methods which were being used. The nature of this study required that only visual inspections be made. Particular emphasis in this report is placed upon observations of construction procedures and design requirements. When the performance data are available, they will be reported. It might be expected that some of the designs appear satisfactory during construction but not stand the test of traffic and weather. Observations of a nature that might prove essential in later performance investigations are reported.

description: This study investigates the factors affecting smallholder farmers’ decisions to adopt Sustainable Agricultural Practices (SAPs) and the impacts of single and multiple SAPs adoption on household food security in the Hauts-Bassins region of Burkina Faso. Data were collected through an individual face-to-face survey with 384 farmers. The study used both the multinomial endogenous switching regression and the average treatment effect model complemented with the multivalued inverse probability weighted regression model for the analyses. Results showed that age, education, cooperative membership, farm size, and access to climate and technology information are some socio-economic determinants of farmers’ decisions to adopt SAPs. Several factors can affect the adoption of SAPs and the impact of adopted SAPs on household welfare. Therefore, adopting single or joint SAPs can’t lead to a positive impact on crop yield, income, and further food security, unless implemented in suitable conditions. Also, the adoption of SAPs may enable food diversification and availability but not cover all aspects of food security. Thus, future studies can deeply explore the impact of SAPs on the different dimensions of food security. Our findings advocate for policies that target reducing constraints faced by farmers in successfully implementing SAPs.
State and Federal Roles in Facilitating Electricity Competition: Legal and Economic Perspectives

subject: electricity restructuring
subject: federalism
subject: regulatory policy

description: Jurisdictions have overlapping authority regarding electricity restructuring when a national authority and subnational regional governments-for example, states-both have a say. The initial sections of the paper review the division of regulatory authority over electricity markets in the United States, constitutional provisions, recent developments, and how federalist concerns have been manifested in antitrust and telecommunications. Justifications for using private markets rather than central governments suggest an efficiency approach to dividing authority, based on information, cross-border externalities, and agency, that is, the ability of a government to reflect the political preferences of its constituents. The goal is not to impose a "right" policy (e.g., promoting efficiency) through a rhetorical "back door," but to set up rules that would best reflect constituent views. This analysis suggests that transmission and environmental regulations should be set on a regional or national level. States should retain control over when and how to open local retail markets. Uncertainty regarding the best way to organize electricity markets warrants localized experimentation. The paper concludes with brief discussions of nonefficiency ethical criteria and transnational considerations.
The "Regulatory Compact" and Implicit Contracts: Should Stranded Costs Be Recoverable?

description: Progress toward electricity market deregulation has brought controversy over whether or not utilities are entitled to compensation for "stranded costs," i.e., costs utilities will not be able to recover due to the advent of competition in their markets. This paper uses a legal and economic analysis of contracts to address the desirability of utility cost recovery. First, underlying principles of law are reviewed to determine whether or not there is a legal presumption of recovery. Then, the analysis considers whether or not an implicit "regulatory compact" between utilities and regulators follows from principles in the economic analysis of law, particularly theories of efficient breach and implicit contracts. The paper concludes that recovery should occur in only a proscribed set of circumstances and that, when called for, compensation should be partial, rather than full.
Preventing Monopoly or Discouraging Competition? The Perils of Price-Cost Tests for Market Power in Electricity

description: Allegations of market power in wholesale electricity sales are typically tested using price-cost margins. Such tests are inherently suspect in markets-such as electricity-that are subject to capacity constraints. In such markets, prices can vary with demand while quantity, and thus cost measure, remain fixed. Erroneous conclusions are more likely when the proxy for marginal cost is the average operating cost of the marginal plant. Measured this way, high Lerner indexes are consistent with competitive behavior. Using this proxy to cap wholesale prices, as the U.S. Federal Energy Regulatory Commission has proposed, would discourage entry by making it impossible for peak power suppliers to recover capital costs. The wholesale electricity sector may be susceptible to market power. But a preferable (if not unproblematic) test for market power would look not at prices but output, i.e., whether individual generators withheld energy that would have been profitable to supply at prevailing prices.
Potential-energy (BCS) to kinetic-energy (BEC)-driven pairing in the attractive Hubbard model

description: The BCS-BEC crossover within the two-dimensional attractive Hubbard model is studied by using the Cellular Dynamical Mean-Field Theory both in the normal and superconducting ground states. Short-range spatial correlations incorporated in this theory remove the normal-state quasiparticle peak and the first-order transition found in the Dynamical Mean-Field Theory, rendering the normal state crossover smooth. For $U$ smaller than the bandwidth, pairing is driven by the potential energy, while in the opposite case it is driven by the kinetic energy, resembling a recent optical conductivity experiment in cuprates. Phase coherence leads to the appearance of a collective Bogoliubov mode in the density-density correlation function and to the sharpening of the spectral function.

description: A process for using curvature invariants is applied to evaluate the metrics for the Alcubierre and the Natario warp drives at a constant velocity.Curvature invariants are independent of coordinate bases, so plotting these invariants will be free of coordinate mapping distortions. As a consequence, they provide a novel perspective into complex spacetimes such as warp drives. Warp drives are the theoretical solutions to Einstein's field equations that allow the possibility for faster-than-light (FTL) travel. While their mathematics is well established, the visualisation of such spacetimes is unexplored. This paper uses the methods of computing and plotting the warp drive curvature invariants to reveal these spacetimes. The warp drive parameters of velocity, skin depth and radius are varied individually and then plotted to see each parameter's unique effect on the surrounding curvature. For each warp drive, this research shows a safe harbor and how the shape function forms the warp bubble. The curvature plots for the constant velocity Natario warp drive do not contain a wake or a constant curvature indicating that these are unique features of the accelerating Natario warp drive.

description: This paper discusses the appropriate balance between traditional gasoline taxes and charging by the mile, focusing mainly on economic efficiency considerations. We begin with a brief discussion of the five major passenger vehicle externalities of concern-local pollution, greenhouse warming, oil dependency, traffic congestion, and traffic accidents-summarizing evidence on the dollar value of the externalities for passenger vehicles in the United States. We then discuss how much fuel taxation might be justified to account for these externalities, as well as how much taxation might be appropriate on fiscal grounds, assuming per-mile charges are unavailable. Finally, we discuss to what extent fuel taxation should be replaced with per-mile charges.

description: We consider a two-phase Darcy flow in a fractured and deformable porous medium for which the fractures are described as a network of planar surfaces leading to so-called hybrid-dimensional models. The fractures are assumed open and filled by the fluids and small deformations with a linear elastic constitutive law are considered in the matrix. As opposed to [10], the phase pressures are not assumed continuous at matrix fracture interfaces, which raises new challenges in the convergence analysis related to the additional interfacial equations and unknowns for the flow. As shown in [16, 2], unlike single phase flow, discontinuous pressure models for two-phase flows provide a better accuracy than continuous pressure models even for highly permeable fractures. This is due to the fact that fractures fully filled by one phase can act as barriers for the other phase, resulting in a pressure discontinuity at the matrix fracture interface. The model is discretized using the gradient discretization method [22], which covers a large class of conforming and non conforming schemes. This framework allows for a generic convergence analysis of the coupled model using a combination of discrete functional tools. In this work, the gradient discretization of [10] is extended to the discontinuous pressure model and the convergence to a weak solution is proved. Numerical solutions provided by the continuous and discontinuous pressure models are compared on gas injection and suction test cases using a Two-Point Flux Approximation (TPFA) finite volume scheme for the flows and $P_2$ finite elements for the mechanics.
Evaluation of Plant Mix Surface Treatments

Year: 1951
Subjects: subject: Transportation Engineering

description: This project made use of six bituminous materials and ten aggregate gradations in plant mix paving operations. The test sections were installed by state forces in 1942 and 1943. The object was to determine which aggregate gradation with a specific bituminous material was best suited for an application of 75 pounds per square yard surface treatment.  The bituminous materials used were MC-5, RC-5, RT-12, PAC-5 (85 to 100 penetration), PAC-7 (120 to 150 penetration), and PAC-8 (150 to 200 penetration). Twenty sections of MC-5 and ten sections of RC-5 were laid in 1942; all the sections containing the other materials were placed in 1943. A lay-out of the project by sections is shown in Fig. 1.  There were three aggregates or aggregate combinations as follows: Limestone, Limestone and Concrete Sand, and Limestone and River Sand. The Limestone type consisted of four gradations made from mixing No. 9 and a fine stone designated as No. 11F. The Limestone and Concrete Sand type consisted of three gradations of No. 9 stone and the coarse sand. The Limestone and River Sand type consisted of three combinations of River Sand and No. 9 stone. These ten gradations are outlined in Table 1 and shown on the gradation chart in Fig. 2.  The gradation range for the 11F stone used in gradings G-1 to G-4 is in Table 1A. This was a much finer stone than the present No. 11 outlined in the same table. A plot of these gradation ranges along with one representing the Kentucky River sand is presented in Fig. 3.

description: How much a policy is expected to cost and who bears the brunt of that cost play a significant role in the debates that shape regulations. We do not have a good track record of predicting costs and their ultimate distribution, but systematic reviews of past assessments have identified some of the factors that lead to errors. A wide range of expected costs of climate policy have been hotly debated, but all are likely to be wrong. This does not mean that we should continue a debate using ill-informed analyses. On the contrary, we need early small experiments to shed light on key unknowns. Environmental stewardship is a long-term challenge and an adaptive regulatory approach promises to inform policy targets and improve controls through sequential regulatory phases that promote: innovation, flexibility and diffusion of best technologies.
A Bayesian analysis of the primordial power spectrum

description: We present a Bayesian analysis of large-scale structure and cosmic microwave background data to constrain the form of the primordial power spectrum. We have extended the usual presumption of a scale invariant spectrum to include: (i) a running spectral index; (ii) a broken spectrum arising perhaps from an interruption of the potential driving inflation; (iii) a large scale cutoff in power as the first year WMAP results appear to indicate; (iv) a reconstruction of the spectrum in eight bins in wavenumber; and (v) a spectrum resulting from a cosmological model proposed by Lasenby & Doran, which naturally exhibits an exponential drop in power on very large scales. The result of our complete Bayesian analysis includes not only the posterior probability distribution from which parameter estimates are inferred but also the Bayesian evidence. This evidence value is greater for a model with fewer parameters unless a more complicated model provides a significantly better fit to the data, thus allowing a powerful method of model selection. We find that those models exhibiting any form of cutoff in power on large scales consistently produce higher evidences than either the Harrison-Zel'dovich or single spectral index spectra. In particular, within the best-fit concordance cosmology, we find the Lasenby & Doran spectrum to show significantly larger evidence as compared to the other models.

Mapping the social clause debate : the potential of the social clause to contribute to the development of an alternative form of economic integration
Creators: name: Long, Andrea Elizabeth
Publisher: name: University of British Columbia
Year: 2009

description: In response to concern about the model of trade and investment liberalization reflected in existing and proposed trade and investment agreements (TIAs), efforts have been made to balance the economic orientation of trade with social considerations. One proposal that has garnered significant attention in this regard is the social clause (SC): a set of labour rights to be attached to the text of TIAs. Although the idea of including labour rights in TIAs seems laudable, significant opposition to the particular SC recommendations developed by Canadian and international labour organizations has emerged. Some critics charge that the addition of a clause to TIAs will not only prove unproductive, but will actually serve to legitimate problematic aspects of these agreements. Others insist that the content of the SC will exacerbate existing inequalities in the international trade order. In this thesis, I reconstruct debate over the SC to determine whether this instrument can effectively contribute to the realization of a more socially responsible trade and investment regime. Using proposals advanced by the Canadian Labour Congress as a key point of reference, I argue that there are resources available to clause proponents to respond to claims that the SC is an inadequate approach to the goal of resisting the current model of liberalization. As such, there is room to resist the conclusion that the SC should be rejected in its entirety. While it may be possible to preserve the SC approach, however, the same cannot be said about the content of current clause proposals. Criticisms of the narrow range of issues covered by existing SC recommendations clearly demonstrate that a rethinking of the content of the clause is not only warranted, but also necessary. Accordingly, I conclude by exploring three considerations that should be factored into the development of what would constitute a more adequate SC: first, existing patterns of inequality in the international trade system; second, the range of issues addressed by the clause; and third, the location of the clause within the context of the international trade regime.

description: Ciudad Juarez, Chihuahua, is home to the U.S.-Mexico border's largest maquiladora labor force, and also its worst air pollution. We marshal two types of evidence to examine the link between maquiladoras and air pollution in Ciudad Juarez, and in its sister city, El Paso, Texas. First, we use a publicly available sector-level emissions inventory for Ciudad Juarez to determine the importance of all industrial facilities (including maquiladoras) as a source of air pollution. Second, we use original plant-level data from two sample maquiladoras to better understand the impacts of maquiladora air pollution on human health. We use a series of computational models to estimate health damages attributable to air pollution from these plants, we compare these damages to estimates of damages from non-maquiladora industrial polluters, and we use regression analysis to determine whether the poor suffer disproportionately from maquiladora air pollution. We find that air pollution from maquiladoras has serious consequences for human health, including respiratory disease and premature mortality. However, maquiladoras are clearly not the leading cause of air pollution in Ciudad Juarez and El Paso. Moreover, most maquiladoras are probably less important sources of dangerous air pollution than at least one notoriously polluting Mexican-owned industry. Finally, we find no evidence to suggest that maquiladora air pollution affects the poor disproportionately.

description: We propose an unified approach to loop quantum gravity and Fedosov quantization of gravity following the geometry of double spacetime fibrations and their quantum deformations. There are considered pseudo-Riemannian manifolds enabled with 1) a nonholonomic 2+2 distribution defining a nonlinear connection (N-connection) structure and 2) an Arnowitt-Deser-Misner 3+1 decomposition. The Ashtekar-Barbero variables are generalized and adapted to the N-connection structure which allows us to write the general relativity theory equivalently in terms of Lagrange-Finsler variables and related canonical almost symplectic forms and connections. The Fedosov results are re-defined for gravitational gauge like connections and there are analyzed the conditions when the star product for deformation quantization is computed in terms of geometric objects in loop quantum gravity. We speculate on equivalence of quantum gravity theories with 3+1 and 2+2 splitting and quantum analogs of the Einstein equations.

This gives an infinite family of topologically distinct asymptotically hyperbolic Einstein manifolds with the same conformal infinity.

description: The possible existence of strange stars in the universe will help in the understanding of various properties of quantum chromodynamics, like asymptotic freedom and chiral symmetry restoration, which is otherwise very difficult to prove in laboratory experiments. Strange star properties were calculated using large $N_c$ approximation with built-in chiral symmetry restoration. A relativistic Hartree Fock calculation was performed using the Richardson potential as an interquark interaction. This potential has the asymptotic freedom and a confinement-deconfinement mechanism built into it and the present calculation employs an application of this potential with modified two scale parameters $Λ$ and $Λ^{\prime}$, to find a new set of equations of state for strange quark matter. The linear confinement string tension from lattice calculations is 350 $MeV$ and the Coulomb -like part has the parameter 100 $MeV$ from deep inelastic scattering experiments. We also consider the effect of temperature, $T$, on gluon mass in a simple way, in addition to the usual density dependence, and find that the transition $T$ from hadronic matter to strange matter is at 80 MeV, close to the 100 MeV estimated in litarature. Therefore formation of strange stars may be the only signal for formation of quark-gluon plasma with asymptotic freedom and chiral symmetry restoration and this may be observable through many processes -such as for example through delayed $γ$ ray afterglow.

A careful treatment of the degeneracy at the axis of rotation for the one dimensional partial differential equation for a parameterization of the generating curve allows us to prove error bounds with respect to discrete $L^2$- and $H^1$-norms for a fully discrete approximation. The theoretical results are confirmed with the help of numerical convergence experiments. We also present numerical simulations for some genus-0 surfaces, including for a non-embedded self-shrinker for mean curvature flow.

Six factors have been critical to the MIS success in Mali: the commitment of policy makers, the financial commitment over the medium term of external funding agencies, developing thorough knowledge of the marketing systems of the country; the choice of the appropriate institutional "home" for managing the system, the development of the human capital for managing the system, the constant targeting of the information needs of the users, which is essential to the financial survival of the system.

ESTONIA • 3 specs; Vohilaid Island, Vohilaid shore (E); Adila Formation, Pirgu Regional Stage; GIT 878-188 to GIT 878-190 • 1 spec.; Salu; Pirgu Regional Stage; TUG 1745-26.
Description
All four specimens are isolated, endogastrically curved mature body chambers, without phragmocone parts. They are identical in size and shape. At the base, their height is 44–45 mm, at the aperture the height measures 36–37 mm, and the total length from base to aperture is ca 50 mm. The three specimens from Vohilaid Island are likely to be slightly deformed (compressed) with a width of ca 29 mm at the body chamber base (CHI = 1.5). In specimen TUG 1745-26, the width is 30 mm where the height is 42 mm (CHI = 1.4). The conch cross section is rounded elliptical at mid body chamber position. At the base of the body chamber, the antisiphuncular margin is more narrow, almost rounded angular. In this latter specimen, traces of a fine transverse annulation are preserved, which is directly transverse, indicating that no hyponomic sinus occurs at the peristome. In lateral view, the antisiphuncular margin is convex and the prosiphuncular margin concave. The conch height decreases nearly continuously toward the aperture resulting in maximum conch heights at or near the base of the body chamber. The siphuncle is nearly marginal, but in all specimens is too poorly preserved to be measured in all specimens.
Remarks
The endogastrically curved and contracted body chambers indicate that these belong to an unknown discosorid species, probably a cyrtogomphoceratid. The form of the body chamber (curved, contracted) in combination with a marginal siphuncle is unknown from any multiceratoid genus. However, because details of the siphuncle and the phragmocone remain unknown a firm determination and erection of a new taxon is not possible with the available material.

In particular, we investigate the feasibility of shuttling donor-bound electrons between the impurity in the bulk and the Si-SiO2 interface by tuning an external electric field. We calculate the shuttling time to range from sub-picoseconds to nanoseconds depending on the distance (~ 10-50 nm) of the donor from the interface. Our results establish that quantum control in such nanostructure architectures could, in principle, be achieved.

However, maintaining a consistent messaging tone for a brand has become more challenging with the virtual explosion in the amount of content which needs to be authored and pushed to the Internet to maintain an edge in the era of digital marketing. To understand the depth of the problem, we collect around 300K web page content from around 650 companies. We develop trait-specific classification models by considering the linguistic features of the content. The classifier automatically identifies the web articles which are not consistent with the mission and vision of a company and further helps us to discover the conditions under which the consistency cannot be maintained. To address the brand inconsistency issue, we then develop a sentence ranking system that outputs the top three sentences that need to be changed for making a web article more consistent with the company's brand personality.

description: Drug administration to the central nervous system (CNS) has become a great obstacle because of several biological barriers, such as the blood-brain barrier, therefore, brain targeting insights are a light for scientists to move forward for treating neurogenerative diseases using advanced non-invasive methods. The current demand is to use a potential direct route as the nasal administration to transport drugs into the brain enhancing the BBB permeability and hence, increasing the bioavailability. Interestingly, recent techniques have been implanted in formulating nanocarriers-based therapeutics for targeting and treating ischemic stroke using lipid or polymeric-based materials. Nanoparticulate delivery systems are set as an effective platform for brain targeting as polymeric nanoparticles and polymeric micelles or nanocarriers based on lipids for preventing drug efflux to promote optimal therapeutic medication concentration in the brain-diseased site. In recent years, there has been a notable increase in research publications and ongoing investigations on the utilization of drug-loading nanocarriers for the treatment of diverse CNS diseases. This review comprehensively depicts these dangerous neurological disorders, drug targeting challenges to CNS, and potential contributions as novel intranasal nano-formulations are being used to treat and regulate a variety of neurological diseases.

description: Non-linear properties of quantum states, such as entropy or entanglement, quantify important physical resources and are frequently used in quantum information science. They are usually calculated from a full description of a quantum state, even though they depend only on a small number parameters that specify the state. Here we extract a non-local and a non-linear quantity, namely the Renyi entropy, from local measurements on two pairs of polarization entangled photons. We also introduce a "phase marking" technique which allows to select uncorrupted outcomes even with non-deterministic sources of entangled photons. We use our experimental data to demonstrate the violation of entropic inequalities. They are examples of a non-linear entanglement witnesses and their power exceeds all linear tests for quantum entanglement based on all possible Bell-CHSH inequalities.

description: Third-generation (3G) gravitational-wave (GW) detectors will be able to observe binary-black-hole mergers (BBHs) up to redshift of $\sim 30$. This gives unprecedented access to the formation and evolution of BBHs throughout cosmic history. In this paper we consider three sub-populations of BBHs originating from the different evolutionary channels: isolated formation in galactic fields, dynamical formation in globular clusters and mergers of black holes formed from Population III (Pop III) stars at very high redshift. Using input from populations synthesis analyses, we created two months of simulated data of a network of 3G detectors made of two Cosmic Explorers and an Einstein Telescope, consisting of $\sim16000$ field and cluster BBHs as well as $\sim400$ Pop III BBHs. First, we show how one can use non-parametric models to infer the existence and characteristic of a primary and secondary peak in the merger rate distribution. In particular, the location and the height of the secondary peak around $z\approx 12$, arising from the merger of Pop III remnants, can be constrained at $\mathcal{O}(10\%)$ level. Then we perform a modeled analysis, using phenomenological templates for the merger rates of the three sub-population, and extract the branching ratios and the characteristic parameters of the merger rate densities of the individual formation channels. With this modeled method, the uncertainty on the measurement of the fraction of Pop III BBHs can be improved to $\lesssim 10\%$, while the ratio between field and cluster BBHs can be measured with an uncertainty of $\sim 50\%$.

description: Many business firms both in the U.S. and abroad are practicing corporate environmental management. They are committed to improving the efficiency of material use, energy use and water use; to recycle; to make safer products and processes and to reduce their overall impact on the environment. In pursuing corporate environmental management, some businesses have found that the presumed tradeoff between profits and environmental quality does not always apply. Instead, by innovating and redesigning their products, processes, corporate culture, and organizational strategy, these firms have been able to improve environmental performance and add to profits. These improved profits are sometimes referred to as "innovation offsets" because they result from technological changes to reduce pollution which also reduce production costs (and/or improve productivity) and thereby "offset" the costs of compliance. The necessary technological innovation is pursued when firms take a dynamic investment perspective rather than presume a static tradeoff between profits and environmental quality.
The Ainu of Tsugaru : the indigenous history and shamanism of northern Japan
Creators: name: Tanaka, Sakurako (Sherry)
Publisher: name: University of British Columbia
Year: 2009

description: This is the first doctoral level Ainu study outside Japan from an indigenous perspective, and the first academic Ainu study ever from a female perspective. This study examines the indigenous history and shamanism of northern Japan, Hokkaido andTsugaru, in the context of the Ainu culture complex. Tsugaru was the last autonomous stronghold of the Ainu people in Honshu, remaining largely independent until it came under the control of the Japanese state, the Edo government, in the seventeenth century. Tsugaru has developed a distinct hybrid culture as a result of gradual mtermixing with non-indigenous populations, though an Ainu consciousness has never completely died out in the region. A comparison between Hokkaido Ainu shamanism and Tsugaru shamanism reveals the relative recentness of their contemporary characteristics, their shared roots prior to the Edo period, as well as changes in gender roles and aspects of gender inequity. In both traditions, shamanism has been transmitted primarily by the female population, and in the past, indigenous women played an essential role in maintaining social and spiritual integrity. The centrality of women came to manifest itself differently in the two regions, due mainly to differing socio-historical circumstances which transformed two originally similar cultures into divergent forms. This study questions the stereotypical ethnic opposition between the Ainu and the "Japanese," and sheds light on the intricate relationship among the Ainu and other indigenous groups in northern Japan. It also questions the powerful Ainu male myth and narratives which shaped much of the Ainu's cultural revival movement in the past century. Firthermore, by revealing a significant level of shared spiritual beliefs and practices between the past and present inhabitants of the Japanese archepelago of Japan and the traditional peoples of Northeast Asia and byond the Bering Strait, the study will point to a need for both Ainu study and Japanese study to be placed within the larger cultural domain, namely, the northern circumpacific region.

description: We investigate whether paradigmatic measurements for quantum state tomography, namely mutually unbiased bases and symmetric informationally complete measurements, can be employed to certify quantum correlations. For this purpose, we identify a simple and noise-robust correlation witness for entanglement detection, steering and nonlocality that can be evaluated based on the outcome statistics obtained in the tomography experiment. This allows us to perform state tomography on entangled qutrits, a test of Einstein-Podolsky-Rosen steering and a Bell inequality test, all within a single experiment. We also investigate the trade-off between quantum correlations and subsets of tomographically complete measurements as well as the quantification of entanglement in the different scenarios. Finally, we perform a photonics experiment in which we demonstrate quantum correlations under these flexible assumptions, namely with both parties trusted, one party untrusted and both parties untrusted.
