description: The implementation of cooperative maneuvers between automated vehicles is a necessary for the improvement of the Advanced Driver Assistence Systems (ADAS). However, the development of these strategies in real vehicles depends on the availability of experimentals platforms, which involves high costs and a lot of testing time. In this line of thought, the present work shows a tool for the design of the Stop & Go cooperative maneuver, making use of a virtual environment for the simulation of a leading vehicle, along with an automated electric vehicle that performs the tracking within a closed circuit. For the design of the maneuver, a V2V communication system between the two platforms will be established, bearing in mind that they execute an automated driving general arhcitecture. The tracking algorithm is based on a fuzzy logic controller, dependent on the leading vehicle speed and the distance between the two vehicles. The results show the usefulness of combining the two test environments for the validation of the cooperative maneuver, reducing the cost and the time in comparison with the real test environment.

description: One of the main problems in modeling the ionised outflows in Active Galactic Nuclei is the unknown distance of the outflowing wind to the central source. Only if the density is known this distance can be determined through the ionisation parameter. Here we study density diagnostics based upon O V transitions. O V is known to have metastable levels that are density dependent. We study the population of those levels under photoionisation equilibrium conditions and determine for which parameter range they can have a significant population. We find that resonance line trapping plays an important role in reducing the critical densities above which the metastable population becomes important. We investigate the K-shell absorption lines from these metastable levels. Provided that there is a sufficient population of the metastable levels, the corresponding K-shell absorption lines are detectable and are well separated from the main absorption line originating from the ground state. We then present the Chandra LETGS spectrum of the Seyfert 1 galaxy Mrk 279 that may show for the first time the presence of these metastable level absorption lines. A firm identification is not yet possible due to both uncertainties in the observed wavelength of the strongest line as well as uncertainties in the predicted wavelength. If the line is indeed due to absorption from O V, then we deduce a distance to the central source of one light week to a few light months, depending upon the importance of additional heating processes.

description: Background: There is a variety of mortality prediction models for patients in intensive care units (ICU) to guide appropriate clinical management. Advances in machine learning methodologies typically employ classifiers such as Neural Network and Random Forest which are often regarded by healthcare professionals as black boxes. These models often do not provide clear links between the input model features and output clinical event. We investigate whether features identified by Cox-Proportional Hazards (CPH) model can be used for ICU mortality prediction. Methods: We employ the PhysioNet Challenge 2012 dataset, a subset of MIMIC-II Clinical Database data of ICU patients admitted to Boston's Beth Israel Deaconess Medical Center from 2001 to 2008. The dataset is split into train set A, test set B and unseen set C, with 4000 patients each. Python is the programming language used alongside scikit-learn, and lifelines packages. Besides white-box feature selection methods (logistic regression and decision tree), we also explore using Cox-Proportional Hazards model for feature selection. We then trained the machine learning model using classifiers such as logistic regression and variants of decision tree. Extreme gradient boosted trees models performed better than other classifiers. The model is validated using 5-fold cross-validation and evaluated against unseen set C. The model performance is assessed using area under the precision-recall curve (AUC-PR) as the main metric. Findings: The data of about 12,000 patients is used, providing a high degree of generalizability. The number of statistically significant features identified by CPH (n = 16) is significantly smaller than logistic regression (n = 36), decision tree (n = 26) and all features (n = 42). With only 16 features used, the model achieves a performance of AUC-PR 0·438 on test set B, which is close to decision tree (AUC-PR 0·442) and logistic regression (AUC-PR 0·446) and all features (AUC-PR 0·446). Interpretation: The significantly fewer features identified by CPH allows the building of a model that is easily interpretable by clinicians whilst still achieving comparable results to other models. This finding allows clinicians to use CPH as an alternative method to determine and act on features that need to be closely monitored for ICU patients.

description: Explicit construction of local observable algebras in quasi-Hermitian quantum theories is derived in both the tensor product model of locality and in models of free fermions. The latter construction is applied to several cases of a $\mathcal{PT}$-symmetric toy model of particle-conserving free fermions on a 1-dimensional lattice, with nearest neighbour interactions and open boundary conditions. Despite the locality of the Hamiltonian, local observables do not exist in generic collections of sites in the lattice. The collections of sites which do contain nontrivial observables strongly depends on the complex potential.

description: Food is the most advertised product in the United States, amounting to $8 to $10 billion in 1980 and accounting for between 3 and 4 cents of each food dollar. Food manufacturers have increased their share of advertising and promotion expense while the retailer's 'share has gone down because of declining use of trading stamps. Promotion by fast food restaurants increased sharply over the past decade. Electronic advertising accounts for about 40 percent of food promotion, while printed and premium promotion account for a fourth each. Couponing, the fastest growing promotion form, accounted for about 11 percent. Between $2 and $4 billion of total food advertising was spent on manufacturers' promotion to the retailer. Advertising and promotion had little impact on increasing total U.S. food consumption, but may have diverted food purchases towards more heavily promoted foods.

description: A survey of the literature and selective data on Federal and State initiatives to promote enterprise growth and development In the private sector reveals that State programs have expanded dramatically and become increasingly dominant since the mid - sixties. State industrial revenue bonds have surpassed Federal business and industrial loans as the major public source for financing industrial activities. While States have become more active in offering incentives to attract new industry, recent studies generally reveal that the costs of these programs to the State and community usually exceed the benefits, that is, tax incentives, by themselves, do not encourage much industrial investment. Federal and State initiatives to manufacturing, the enterprise most sought after by State and local developers, merely serve to reshuffle a relatively fixed number of plants and jobs from one State or region to another without appreciably expanding the number of plants and jobs nationwide.

description: Public sentiment routinely supports public-sector investment in infrastructure. Moreover, this view exists in both rural and metropolitan settings. Often, government is expected to directly support or, at least, guide the provision of transportation, telecommunications, and various utility services by supplying some or all of the necessary facilities. The current paper, first develops a more precise economic explanation for why public-sector infrastructure investment is economically efficient public policy. Next, by specifically accounting for the spatial nature of network infrastructures and commerce, we describe why many necessary investments must be sited in and/or available to rural communities. Finally, with an admittedly speculative eye to the future, we offer tentative forecasts regarding the nature and value of efficient, forward-looking rural infrastructure outcomes.

description: As directed by the American Recovery and Reinvestment Act of 2009, the US Department of Transportation (DOT) created the Transportation Investment Generating Economic Recovery (TIGER) discretionary grant program for surface transportation infrastructure projects. Through 2013, there have been five rounds of the grant program. TIGER uses a multi-step competitive application process to award surface transportation funds. TIGER applications are initially screened by US DOT’s staff of technical experts. For projects forwarded by the review team, US DOT economic experts then review the applicant’s benefit-cost analysis (BCA) and attempt to determine the likelihood that the benefits exceeded costs (i.e. not the applicant’s self-determination). The final awardees are then selected by a Review Team of Modal Administrators and DOT Office of the Secretary level officials. The purpose of this paper is to discuss many of the common errors in preparing, and issues in reviewing the applicant’s BCA and in making a net benefit determination. A secondary purpose is to determine if the most deserving projects, based on an applicant’s BCA and the likelihood that benefits exceeded costs, are more likely to receive grant funding. We do so for the second through the fifth rounds of the program.

description: In this paper, we take a step toward understanding the rate of return to government efforts to promote broadband. Specifically, we evaluate the impact of USDA’s broadband loan and grant programs on the average payroll per worker using zip code level data from the Zip Code Business Patterns for the period from 1997 to 2007. Because we employ data on the size of the loans and grants, we are able to produce a rough estimate of the rate of return on such investments. Our results indicate that a $1 increase in zip code per capita broadband loan results in about a $1.08 increase in payroll per worker. Results were nearly identical for the pilot broadband loans ($1.07 increase in payroll per worker for each additional loan dollar). We find no statistically significant impact of broadband grants received on the payroll per worker. Rough benefit-cost calculations suggest that total benefits from the current loan program substantially outweigh costs, with benefit-cost ratios ranging from 2.8 to 5.7 depending on assumptions about discount rates.

description: We prove the stability of contact discontinuities without shear, a family of special discontinuous solutions for the three-dimensional full Euler systems, in the class of vanishing dissipation limits of the corresponding Navier-Stokes-Fourier system. We also show that solutions of the Navier-Stokes-Fourier system converge to the contact discontinuity when the initial datum converges to the contact discontinuity itself. This implies the uniqueness of the contact discontinuity in the class that we are considering. Our results give an answer to the open question, whether the contact discontinuity is unique for the multi-D compressible Euler system. Our proof is based on the relative entropy method, together with the theory of $a$-contraction up to a shift.

description: This paper reviews literature on the impacts, costs, and benefits of infrastructure in the United States and developing countries, focusing on studies published since the early 1990s. A review of 28 econometric studies of productivity impacts of public capital in the United States found a wide range of estimates of the output elasticity of public capital (a measure of the percent increase in the value of output associated with a one percent increase in the value of the public capital stock) – ranging from -0.49 to +0.56, with a mean value of 0.12. The range of estimates depends on the unit of analysis, the type of public capital, and the method of analysis. Generally larger productivity impacts were found in national than in state-level studies and for water and sewer capital than for highway capital. Smaller impacts were found in studies that controlled for state-level fixed factors that affect productivity. These estimates imply an even wider range of estimates of the marginal rate of return to public capital stocks, ranging from close to zero for highway stocks to nearly 90 percent for water and sewer capital. Similarly large ranges of rates of return were estimated by studies investigating impacts of public capital on the costs or profits of firms. A few studies estimated the benefits of public capital stocks in U.S. cities including amenity benefits, and found that such benefits can be larger than the productivity benefits. The benefit-to-cost ratio (BCR) of public capital stocks estimated in these studies ranged from about 0.3 to greater than 2.0, depending on the assumptions of the econometric framework. Many econometric studies have investigated impacts of particular types of infrastructure in the U.S. and in developing countries, though few have estimated rates of return implied by the estimates. Model-based estimates of BCRs of infrastructure investments by the U.S. Army Corps of Engineers and the Federal Highway Administration suggest that BCRs greater than 1.0 are common for water and highway infrastructure projects, but no evidence was found in the literature reviewed that these have been validated using econometric approaches. Rigorous econometric impact evaluation methods to assess the causal impacts of infrastructure investments have been used by the Millennium Challenge Corporation and multilateral development banks to validate and improve the results of predictive models in some developing country contexts and have found some statistically significant impacts on railroads, roads, rural electrification, water and information and communication technologies (ICTs). Such an approach could be useful to apply in more contexts.

Predicting Quantum Decoherence from Spacetime Structure: A Machine Learning Test of the Fractal Physis Model

description: We present the first machine-learned, predictive model of quantum decoherence derived from local structural features of spacetime. Extending the Fractal Physis framework, this work demonstrates that quantum decoherence is not a fundamentally stochastic or observer-driven event, but can be forecast directly from curvature, entropy, field stress, and material phase.

Using a dataset of 20,000 synthetic spacetime zones encoded with ten physical features, we train a dense neural network to predict the local decoherence susceptibility field with 92% accuracy and an AUC of 0.994. This field governs the decoherence strength within Fractal Physis, enabling real-time prediction of interference loss with no measurement context.

This release includes all training code, full feature mapping, model checkpoints, visibility simulation functions, and evaluation plots. It provides the first open-source, structure-driven decoherence predictor - fully testable, falsifiable, and laboratory-relevant.

These results mark a transition from interpretive decoherence to predictive physics: decoherence is not random, it is structural, measurable, and now machine-learned.

description: An analytic representation of the short-range repulsion energy in ionic systems is described that allows for the fact that ions may change their size and shape depending on their environment. This function is extremely efficient to evaluate relative to previous methods of modeling the same physical effects. Using a well-defined parametrization procedure we have obtained parameter sets for this energy function that reproduce closely the density functional theory potential energy surface of bulk MgO. We show how excellent agreement can be obtained with experimental measurements of phonon frequencies and temperature and pressure dependences of the density by using this effective potential in conjunction with ab initio parametrization.

description: The characteristic difference between a black hole and other exotic compact objects (ECOs) is the presence of the horizon. The horizon of a classical black hole acts as a one-way membrane. Due to this nature, any perturbation on the black hole must satisfy ingoing boundary conditions at the horizon. For an ECO either the horizon is replaced or modified with a surface with non zero reflectivity. This results in a modification of the boundary condition of the perturbation around such systems. In this work, we study how tidal heating of an ECO gets modified due to the presence of a reflective surface and what implication it brings for the gravitational wave observations. We also argue that the position of the reflective surface, $\varepsilon$ $\gtrsim \mathcal{O}(10^{-5})$, can have an observational impact in extreme mass ratio inspirals.

description: The Sender Policy Framework (SPF) is a basic mechanism for authorizing the use of domains in email. In combination with other mechanisms, it serves as a cornerstone for protecting users from forged senders. In this paper, we investigate the configuration of SPF across the Internet. To this end, we analyze SPF records from 12 million domains in the wild. Our analysis shows a growing adoption, with 56.5 % of the domains providing SPF records. However, we also uncover notable security issues: First, 2.9 % of the SPF records have errors, undefined content or ineffective rules, undermining the intended protection. Second, we observe a large number of very lax configurations. For example, 34.7 % of the domains allow emails to be sent from over 100 000 IP addresses. We explore the reasons for these loose policies and demonstrate that they facilitate email forgery. As a remedy, we derive recommendations for an adequate configuration and notify all operators of domains with misconfigured SPF records.

description: In recent years, an approach to extremum seeking control made it possible to design control vector fields that lead to asymptotic stability of the minimum point provided that the minimum value of the function is known a priori. In this work, we aim to relax that assumption. We propose an extremum-seeking control law that converges to the minimum point with vanishing control oscillations, without access to the minimum value of the cost function. We provide a numerical example to support our results.

The form of the potential is motivated by the dimensional reduction of M-theory with non-trivial four-form flux on a maximally symmetric internal space. To describe the asymptotic features of run-away solutions we introduce the concept of a `quasi fixed point.' We give the complete classification of solutions according to their late-time behavior (accelerating, decelerating, crunch) and the number of periods of accelerated expansion.

description: While deep learning strategies achieve outstanding results in computer vision tasks, one issue remains: The current strategies rely heavily on a huge amount of labeled data. In many real-world problems, it is not feasible to create such an amount of labeled training data. Therefore, it is common to incorporate unlabeled data into the training process to reach equal results with fewer labels. Due to a lot of concurrent research, it is difficult to keep track of recent developments. In this survey, we provide an overview of often used ideas and methods in image classification with fewer labels. We compare 34 methods in detail based on their performance and their commonly used ideas rather than a fine-grained taxonomy. In our analysis, we identify three major trends that lead to future research opportunities. 1. State-of-the-art methods are scaleable to real-world applications in theory but issues like class imbalance, robustness, or fuzzy labels are not considered. 2. The degree of supervision which is needed to achieve comparable results to the usage of all labels is decreasing and therefore methods need to be extended to settings with a variable number of classes. 3. All methods share some common ideas but we identify clusters of methods that do not share many ideas. We show that combining ideas from different clusters can lead to better performance.

description: Discrete dynamic programming, widely used in addressing optimization over time, suffers from the so-called curse of dimensionality, the exponential increase in problem size as the number of system variables increases. One method to partially address this problem is to avoid the use of state transition probability matrices, which grow in the square of the size of the state space. This can be done through the use of expected value (EV) functions, which compute the expectation of functions of the future state variables conditioned on current variables. Two ways that this leads to potential gains arise when the state transition can be broken into separate phases and when the transitions for different state variables are conditionally independent. Both of these situations arise in models that are used in natural resource management and are illustrated with several examples.

description: Numerous control problems in economics can be characterized as optimal switching problems, including optimal stopping and entry/exit problems. With certain notable exceptions, solutions to such problems must be computed numerically. This paper discusses an approach to obtaining a numerical solution in a fairly general setting and describes a user-friendly MATLAB implementation that simplifies that process.

description: Let $Γ$ be a torsion-free lattice of $\text{PU}(p,1)$ with $p \geq 2$ and let $(X,μ_X)$ be an ergodic standard Borel probability $Γ$-space. We prove that any maximal Zariski dense measurable cocycle $σ: Γ\times X \longrightarrow \text{SU}(m,n)$ is cohomologous to a cocycle associated to a representation of $\text{PU}(p,1)$ into $\text{SU}(m,n)$, with $1 < m \leq n$. The proof follows the line of Zimmer' Superrigidity Theorem and requires the existence of a boundary map, that we prove in a much more general setting. As a consequence of our result, it cannot exist a maximal measurable cocycle with the above properties when $n\neq m$.

description: We offer a unified numerical method to solve both impulse and barrier control problems in multidimensional state spaces. Our numerical approach is based on the link between optimal regime switching model and impulse and barrier control problems. This link results in a convenient representation of the optimality conditions for numerical solution methods. Using finite difference approximations for derivatives, the optimality conditions are transformed into an extended vertical linear complementarity problem which is solved using Newton type methods. The numerical approach is illustrated with several examples.

description: Large compilations of heterogeneous environmental observations are increasingly available as public databases, allowing researchers to test hypotheses across datasets. Statistical complexities arise when analyzing compiled data due to unbalanced spatial sampling, variable environmental context, mixed measurement techniques, and other reasons. Hierarchical Bayesian modeling is increasingly used in environmental science to describe these complexities, however few studies explicitly compare the utility of hierarchical Bayesian models to simpler and more commonly applied methods. Here we demonstrate the utility of the hierarchical Bayesian approach with application to a large compiled environmental dataset consisting of 5,741 marine vertical organic carbon flux observations from 407 sampling locations spanning eight biomes across the global ocean. We fit a global scale Bayesian hierarchical model that describes the vertical profile of organic carbon flux with depth. Profile parameters within a particular biome are assumed to share a common deviation from the global mean profile. Individual station-level parameters are then modeled as deviations from the common biome-level profile. The hierarchical approach is shown to have several benefits over simpler and more common data aggregation methods. First, the hierarchical approach avoids statistical complexities introduced due to unbalanced sampling and allows for flexible incorporation of spatial heterogeneitites in model parameters. Second, the hierarchical approach uses the whole dataset simultaneously to fit the model parameters which shares information across datasets and reduces the uncertainty up to 95% in individual profiles. Third, the Bayesian approach incorporates prior scientific information about model parameters; for example, the non-negativity of chemical concentrations or mass-balance, which we apply here. We explicitly quantify each of these properties in turn. We emphasize the generality of the hierarchical Bayesian approach for diverse environmental applications and its increasing feasibility for large datasets due to recent developments in Markov Chain Monte Carlo algorithms and easy-to-use high-level software implementations.

X-ray/UV Campaign on the Mrk 279 AGN Outflow: Constraining Inhomogeneous Absorber Models

description: We investigate the applicability of inhomogeneous absorber models in the formation of AGN outflow absorption-troughs. The models we explore are limited to monotonic gradients of absorbing column densities in front of a finite emission source. Our main finding is that simple power-law and gaussian distributions are hard pressed to fit the Mrk 279 high-quality UV outflow data. An acceptable fit for the O VI troughs can only be obtained by assuming unrealistic optical depth values (upward of 100). The strongest constraints arise from the attempt to fit the Lyman series troughs. In this case it is evident that even allowing for complete freedom of both the power-law exponent and the optical depth as a function of velocity cannot yield an acceptable fit. In contrast, partial covering models do yield good fits for the Lyman series troughs. We conclude that monotonic inhomogeneous absorber models that do not include a sharp edge in the optical depth distribution across the source are not an adequate physical model to explain the trough formation mechanism for the outflow observed in Mrk 279.

description: Domestic subsidies on dairy products became an issue between Australia and New Zealand in the early eighties when these countries began discussing a new free—trade agreement. Subsidies alter the production and marketing efficiency in their dairy industries and affect the degree to which Australia's and New Zealand's dairy industries compete in each other's domestic and international markets. The Australian dairy industry is more heavily subsidized than New Zealand's. Removing the subsidies in both countries would favor New Zealand's competitive position in Australia's domestic and international markets.

description: The capture and subsequent in--spiral of compact stellar remnants by central massive black holes, is one of the more interesting likely sources of gravitational radiation detectable by LISA. The relevant stellar population includes stellar mass black holes, and possibly intermediate mass black holes, generally on initially eccentric orbits. Predicted detectable rates of capture are highly uncertain, but may be high enough that source confusion is an issue. Foreground events with relatively high signal-to-noise ratio may provide important tests of general relativity. I review the rate estimates in the literature, and the apparent discrepancy between different authors' estimates, and discuss some of the relevant uncertainties and physical processes. The white dwarf mergers rate are uncertain by a factor of few; the neutron star merger rate is completely uncertain and likely to be small; the black hole merger rate is likely to be dominant for detectable mergers and is uncertain by at least two orders of magnitude, largely due to unknown physical conditions and processes. The primary difference in rate estimates is due to different initial conditions and less directly due to different estimates of key physical processes, assumed in different model scenarios for in-spiral and capture.
