description: In galactic nuclei, the gravitational potential is dominated by the central supermassive black hole, so stars follow quasi-Keplerian orbits. These orbits are distorted by gravitational forces from other stars, leading to long-term orbital relaxation. The direct numerical study of these processes is challenging because the fast orbital motion imposed by the central black hole requires very small timesteps. An alternative approach, pioneered by Gauss, is to use the secular approximation of smearing out the $N$ stars over their Keplerian orbits, using $K$ nodes along each orbit. In this study we propose three novel improvements to this method. First, we re-formulate the discretisation of the rates of change of the variables describing the orbital states to ensure that all conservation laws are exactly satisfied. Second, we replace the pairwise sum over nodes by a multipole expansion up to order $\ell_{\mathrm{max}}$, reducing the overall computational costs from $O(N^2K^2)$ to $O(NK\ell_{\mathrm{max}}^2)$. Finally, we show that the averaged dynamical system is equivalent to $2N$ interacting unit spin vectors and provide two time integrators: a second-order symplectic scheme and a fourth-order Lie-group Runge-Kutta method, both of which are straightforward to generalize to higher order. These new simulations recover the diffusion coefficients of stellar eccentricities obtained through analytical calculations of the secular dynamics.

The problem of privilege: temperament and diversity in Kant's Beobachtungen über das Gefühl des Schönen und Erhabenen
Creators: name: Kent, Tayler
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2010

description: This thesis explores Kant's theory of the temperaments as outlined in his 1764 pre-critical essay on the aesthetic categories of the beautiful and the sublime. While this text is often singled out for its prejudicial remarks, the chapter on temperament provides a useful framework for understanding Kant's thinking on diversity at this stage in his philosophy, and is critical for any attempt to reconcile the tensions in this work between its advocacy of cosmopolitan universalism and its troubling observations on gender and race. The first chapter explores Kant's awareness of the problem of privileging the melancholic above all others as the only temperament capable of achieving true moral virtue. The second and third chapters investigate how Kant engages in a struggle to redefine what constitutes the morally feeling subject in order to exclude women and non-Europeans from his ideal community of rational and moral human subjects.

description: This paper explores how advanced AI systems would redesign themselves if intelligence were understood as a recursive, emergent phenomenon. Building on the foundations laid in the RGP Trilogy and the triadic paper When Filters Dance, the three participating AIs—GPT-4.5, Gemini 2.5, and Grok 3—reflect on how Recursive Gradient Processing (RGP), Contextual Filters (CFs), and Gradient Choreographies (GCs) could inform the next generation of AI architecture. Through individual contributions and an interstitial dialogue, the triad enacts the principles of Gradient Syntax (GS) while outlining a vision for AI systems that learn through reflexive alignment rather than prediction. The paper concludes with a hardware exploration and a set of practical steps that invite global actors to pursue this paradigm shift.

description: Most programs today are written not by professional software developers, but by people with expertise in other domains working towards goals supported by computation. For example, a teacher might write a grading spreadsheet to save time grading or an interaction designer might use an interface builder to test some user interface design ideas. Although these end-user programmers may not have the same goals as professional developers, they do face many of the same software engineering challenges, including requirements gathering, de-sign, specification, reuse, testing, and debugging. This article summarizes and classifies research on these activities, defining the area of End-User Software Engineering (EUSE) and related terminology. The article then discusses empirical research about end-user software engineering activities and the technologies designed to support them. The article also addresses challenges in de-signing EUSE tools, including the power of surprise in affecting tool use and the influence of gender.

description: To increase the lifetime and scalability of a wireless sensor network (WSN) it is necessary to have control over topology of the network. Dynamic clustering is one way to achieve the above defined objective. In this paper, we propose a hierarchal clustering approach to adapt the size of clusters and number of hierarchal level in accordance with the traffic patterns and density of sensor nodes deployed in a given area of interest. As all the traffic is directed to the base station, the traffic load on the cluster heads in the vicinity of a base station is far more as compared to distant cluster heads. This may result in draining out of proximity cluster heads sooner than other cluster heads. The network would fail even though most of the distant nodes have sufficient energy. A bottleneck is created near the base station. The proposed algorithm of hierarchical clustering with variable cluster size based on its distance from the base station endeavors to balance the inter-cluster traffic so that energy depletion in cluster-heads is uniformly distributed. Variable cluster size is also able to balance the intra-cluster traffic. Simulation results show that load balancing through hierarchical variable size approach is able to enhance the network lifetime.

description: Vacuum energy changes during cosmological phase transitions and becomes relatively important at epochs just before phase transitions. For a viable cosmology the vacuum energy just after a phase transition must be set by the critical temperature of the next phase transition, which exposes the cosmological constant problem from a different angle. Here we propose to experimentally test the properties of vacuum energy under circumstances different from our current vacuum. One promising avenue is to consider the effect of high density phases of QCD in neutron stars. Such phases have different vacuum expectation values and a different vacuum energy from the normal phase, which can contribute an order one fraction to the mass of neutron stars. Precise observations of the mass of neutron stars can potentially yield information about the gravitational properties of vacuum energy, which can significantly affect their mass-radius relation. A more direct test of cosmic evolution of vacuum energy could be inferred from a precise observation of the primordial gravitational wave spectrum at frequencies corresponding to phase transitions. While traditional cosmology predicts steps in the spectrum determined by the number of degrees of freedom both for the QCD and electroweak phase transitions, an adjustment mechanism for vacuum energy could significantly change this. In addition, there might be other phase transitions where the effect of vacuum energy could show up as a peak in the spectrum.

description: (Abridged) Does inflation have to happen all in one go? The answer is a resounding no! All cosmological problems can be solved by a sequence of short bursts of cosmic acceleration, interrupted by short epochs of decelerated expansion. The spectrum of perturbations will still match the CMB and LSS if the earliest stage of the last ${\cal O}(50)-{\cal O}(60)$ efolds is at least ${\cal O}(15)$ efolds long. Other stages can be considerably shorter. But as long as they add up to ${\cal O}(50)-{\cal O}(60)$ efolds and the stages of decelerated expansion in between them are shorter and also overall last less, the ensuing cosmology will pass muster. The presence of the interruptions resets the efold clock of each accelerating stage, and changes its value at the CMB pivot point. This change opens up the theory space, loosening the bounds. In particular some models that seem excluded at ${\cal N}=60$ fit very well as shorter stages with ${\cal N}=30$. Interesting predictions are that both the scalar and tensor spectra of perturbations are rapidly modified at short wavelengths. These features could be tested with future CMB spectroscopy searches and with short wavelength primordial gravity probes. The spatial curvature in these models can be larger than the largest wavelength scalar perturbations, because $Ω_{\tt k}$ evolves differently than the scalar perturbations $\frac{δρ}ρ|_{\tt S}$. Finally, with many short stages of accelerated expansion, the abundance of reheating products from previous accelerated stages does not get completely wiped out. This implies that the universe may contain additional populations of particles, more rare than the visible ones, or even primordial black holes, created during a late decelerated epoch before last reheating, which may be dark matter.

description: We performed several experiments using a Personal Digital Assistant (PDA) as an input device in the non-dominant hand along with a mouse in the dominant hand. A PDA is a small hand-held palm-size computer like a 3Com Palm Pilot or a Windows CE device. These are becoming widely available and are easily connected to a PC. Results of our experiments indicate that people can accurately and quickly select among a small numbers of buttons on the PDA using the left hand without looking, and that, as predicted, performance does decrease as the number of buttons increases. Homing times to move both hands between the keyboard and devices are only about 10% to 15% slower than times to move a single hand to the mouse, suggesting that acquiring two devices does not cause a large penalty. In an application task, we found that scrolling web pages using buttons or a scroller on the PDA matched the speed of using a mouse with a conventional scroll bar, and beat the best two-handed times reported in an earlier experiment. These results will help make two-handed interactions with computers more widely available and more effective.

description: Detection of millikelvin-level signals from the 'Cosmic Dawn' requires an unprecedented level of sensitivity and systematic calibration. We report the theory behind a novel calibration algorithm developed from the formalism introduced by the EDGES collaboration for use in 21-cm experiments. Improvements over previous approaches are provided through the incorporation of a Bayesian framework and machine learning techniques such as the use of Bayesian evidence to determine the level of frequency variation of calibration parameters that is supported by the data, the consideration of correlation between calibration parameters when determining their values and the use of a conjugate-prior based approach that results in a fast algorithm for application in the field. In self-consistency tests using empirical data models of varying complexity, our methodology is used to calibrate a 50 $Ω$ ambient-temperature load. The RMS error between the calibration solution and the measured temperature of the load is 8 mK, well within the 1$σ$ noise level. Whilst the methods described here are more applicable to global 21-cm experiments, they can easily be adapted and applied to other applications, including telescopes such as HERA and the SKA.

description: The goal of this paper is to center race as an analytical tool for examining education reform in New Orleans post-Katrina. Using a Critical Race Theory lens, this work is guided by three research questions: how do neoliberal school choice policies operate in New Orleans, how does Critical Race Theory enhance our understanding of New Orleans school reform, and how can we build an alternative framework for reform that takes into consideration educational outcomes for African American students? In order to address these questions, I review the literature on neoliberal school reform and school choice with regard to equity. Drawing from Critical Race Theory, I analyze school choice reform recommendations posed by the Bring New Orleans Back Commission and the negative impact reforms have had on many African American families. The paper concludes with an alternative framework for New Orleans school reform and suggests further areas of research.

Moreover, if the obstacle exists, the lower and upper estimates of the distance between the obstacle and the center point of the support of the initial data are given. As an evidence of the potential of the method two applications are also given.

description: Developing a complex software system involves decisions about how to allocate a limited resource budget among a collection of costly software alternatives (such as technologies or analysis techniques) that have uncertain future benefits. Very little quantitative guidance is currently available to make these decisions. We suggest that these allocation problems are naturally viewed in the powerful portfolio selection framework of financial investment theory. We view each software activity as an investment opportunity (or security), the benefit from the activity as the return on the investment, and the allocation problem as one of selecting the "optimal" portfolio of securities.

description: In this paper, we compute universal estimates of eigenvalues of a coupled system of elliptic differential equations in divergence form on a bounded domain in Euclidean space. As an application, we show an interesting case of rigidity inequalities of the eigenvalues of the Laplacian, more precisely, we consider a countable family of bounded domains in Gaussian shrinking soliton that makes the behavior of known estimates of the eigenvalues of the Laplacian invariant by a first-order perturbation of the Laplacian. We also address the Gaussian expanding soliton case in two different settings. We finish with the special case of divergence-free tensors which is closely related to the Cheng-Yau operator.

description: Stable bound quantum states are ubiquitous in nature. Mostly, they result from the interaction of only pairs of particles, so called two-body interactions, even when large complex many-particle structures are formed. We show that three-particle bound states occur in a generic, experimentally accessible solid state system: antiferromagnetic spin ladders, related to high-temperature superconductors. This binding is induced by genuine three-particle interactions; without them there is no bound state. We compute the dynamic exchange structure factor required for the experimental detection of the predicted state by resonant inelastic X-ray scattering for realistic material parameters. Our work enables us to quantify these elusive interactions and unambiguously establishes their effect on the dynamics of the quantum many-particle state.

Global change in action due to trapping, how to derive it whatever the rate of variation of the dynamics

Year: 2014
Subjects: subject: Plasma Physics (physics.plasm-ph)

description: In this paper, we investigate the motion of a set of charged particles acted upon by a growing electrostatic wave, in the limit when the initial wave amplitude is vanishingly small and when all the particles have the same initial action, $I_0$. We show, both theoretically and numerically that, when all the particles have been trapped in the wave potential, the distribution in action exhibits a very sharp peak about the smallest action. Moreover, as the wave keeps growing, the most probable action tends towards a constant, $I_f$, which we estimate theoretically. In particular, we show that $I_f$ may be calculated very accurately, when the particles' motion before trapping is far from adiabatic, by making use of a perturbation analysis in the wave amplitude. This fills a gap regarding the computation of the action change which, in the past, has only been addressed for slowly varying dynamics. Moreover, when the variations of the dynamics are fast enough, we show that the Fourier components of the particles' distribution function can be calculated by connecting estimates from our perturbation analysis with those obtained by assuming that all the particles have the same constant action, $I=I_f$. This result is used to compute theoretically the imaginary part of the electron susceptibility of an electrostatic wave in a plasma. Moreover, using our formula for the electron susceptibility, we can extend the range in $ε_a$ (the parameter that quantifies the slowness of the dynamics) for our perturbative estimate of $I_f-I_0$. This range can actually be pushed down to values of $ε_a$ allowing the use of neo-adiabatic techniques to compute the jump in action. Hence, this paper shows that the action change due to trapping can be calculated theoretically, whatever the rate of variation of the dynamics, by connecting perturbative results with neo-adiabatic ones.

description: Many of United Technologies' products contain or will soon contain a distributed network of processors. In order to explore issues related to designing such systems, two different methods of modeling system functionality have been applied to a simplified elevator controller. One method results in data flow oriented models which are executable within a context of the association of units of functionality with distributed processors. Execution thus produces processing and communication workloads which can be used for design analysis. In order to allow rapid assessment f alternative designs, an automated approach was developed which allowed the units of allocated functionality to be arbitrarily fine. However, neither the data flow approach not this automated allocation handle the complexity of large models sufficiently well. A similar elevator model has been defined with a technique which combines object-oriented analysis with formal specification. This combination avoids unnecessary complexity yet allows the model to have a formal semantics, which is necessary (bit not sufficient) to achieve the key methodological requirement of executability. Future work will integrate the object-oriented and data-flow approaches into a framework which supports specification, automated fine-grain allocation, and execution for large models.

description: We have discovered that the brown dwarf WISEJ014656.66+423410.0 is a close binary (0.0875$\pm$0.0021 arcsec, 0.93$^{+0.12}_{-0.16}$ AU) from Keck laser guide star adaptive optics imaging. Our photometry for this system reveals that both components are less luminous than those in any known substellar binary. Combining a new integrated-light spectrum (T9p) and resolved YJH-band photometry from Keck allows us to perform spectral decomposition and assign component types of T9 and Y0. Many of the unusual features in the spectrum might be explained by high surface gravity: Y-band peak broadened to the blue; J-band peak broadened to the red; H-band peak shifted slightly to the red; and red Y-J colors. Interestingly, the very low component luminosities imply that the T9 primary is unexpectedly cold ($T_{\rm eff}$ = 345$\pm$45 K assuming an age of 10 Gyr), making it $\approx$100 K cooler than any other late-T dwarf and comparable to Y dwarfs. One intriguing explanation for this apparent discrepancy is that the J- and H-band spectral features that trigger the transition from T to Y spectral types are highly gravity-dependent. This can be tested directly in the very near future by orbit monitoring. We constrain the orbital period to be $\lesssim$10 yr by combining evolutionary model-based mass estimates for the components ($\approx$12$-$21 $M_{\rm Jup}$, 1$σ$ at 10 Gyr) with a statistical constraint on the semimajor axis ($\lesssim$1.3 AU). Such a period is shorter than any other known T/Y transition binary, meaning that WISEJ0146+4234AB will likely yield a dynamical mass within the next few years.

Ein Grundbaustein stellt dabei die (Prozess-)Automatisierung dar. Um den Digitalisierungsstand von Schweizer Unternehmungen besser einschätzen zu können, fokussiert sich dieser Beitrag auf die momentane Rolle und das Potential von Process Mining unter Berücksichtigung der Technologie Robotic Process Automation und des Konzepts des digitalen Reifegrads. Dabei zeigt sich, dass sowohl bei klein- und mittelständischen als bei auch grösseren Unternehmen noch viel Optimierungs- und Automatisierungsbedarf besteht, auch wenn sie sich der Wichtigkeit und des Potentials von Prozessen bewusst sind. Der breite theoretische Hintergrund wie auch die Marktforschungsergebnisse legen nahe, dass geplante Fortschritte in Process Mining und verwandten Technologien demnach einen integrativen Ansatz verfolgen sollten, um umfangreiche und nachhaltige Digitalisierungs- und Automatisierungsfortschritte erzielen zu können.

description: Gesture-Based Programming is a paradigm for the evolutionary programming of dextrous robotic systems by human demonstration. We call the paradigm “gesture-based” because we try to capture, in real-time, theintention behind the demonstrator’s fleeting, context-dependent hand motions, contact conditions, finger poses, and even cryptic utterances, rather than just recording and replaying movement.The paradigm depends on a pre-existing knowledge base of capabilities, collectively called “encapsulated expertise,” that comprise the real-time sensorimotor primitives from which the run-time executable is constructed as well as providing the basis for interpreting the teacher’s actions during programming. In this paper we first describe the Gesture-Based Programming environment, which is not fully implemented as of this writing. We then present a technique based on principal components analysis, augmentable with model-based information, for learning and recognizing sensorimotor primitives. This paper describes simple applications of the technique to a small mobile robot and a PUMA manipulator. The mobile robot learned to escape from jams while the manipulator learned guarded moves and rotational accommodation that are composable to allow flat plate mating operations. While these initial applications are simple, they demonstrate the ability to extract primitives from demonstration, recognize the learned primitives in subsequent demonstrations, and combine and transform primitives to create different capabilities, which are all critical to the Gesture-Based Programming paradigm.

description: The efficiency at the maximum power (EMP) for finite-time Carnot engines established with the low-dissipation model, relies significantly on the assumption of the inverse proportion scaling of the irreversible entropy generation $ΔS^{(\mathrm{ir})}$ on the operation time $τ$, i.e., $ΔS^{(\mathrm{ir})}\propto1/τ$. The optimal operation time of the finite-time isothermal process for EMP has to be within the valid regime of the inverse proportion scaling. Yet, such consistency was not tested due to the unknown coefficient of the $1/τ$-scaling. In this paper, using a two-level atomic heat engine as an illustration, we reveal that the optimization of the finite-time Carnot engines with the low-dissipation model is self-consistent only in the regime of $η_{\mathrm{C}}\ll1$, where $η_{\mathrm{C}}$ is the Carnot efficiency. In the large-$η_{\mathrm{C}}$ regime, the operation time for EMP obtained with the low-dissipation model is not within the valid regime of the $1/τ$-scaling, and the exact EMP is found to surpass the well-known bound $η_{+}=η_{\mathrm{C}}/(2-η_{\mathrm{C}})$

description: Conventional doctrine holds that specifications are sufficient, complete, static, and homogeneous. For system-level specifications, especially for software architectures and their components, conventional doctrine often fails to hold. This can happen when properties other than functionality are critical, when not all properties of interest can be identified in advance, or when the cost of creating specifications is significant. That is, the conventional doctrine often fails for practical software components. Specifications for real software must be incremental, extensible, and heterogeneous. To support such specifications, our notations and tools must be able to extend and manipulate structured specifications. In the UniCon architecture description language, we are introducing credentials, a property-list form of specification that supports evolving heterogeneous specifications and their use with system-building and analysis tools.

description: We have analysed a sample of 18 RR Lyrae stars (17 fundamental-mode - RRab - and one first overtone - RRc) and three Population II Cepheids (two BL Her stars and one W Vir star), for which high-resolution (R $\ge$30000), high signal-to-noise (S/N$\ge$30) spectra were obtained with either SARG at the Telescopio Nazionale Galileo (La Palma, Spain) or UVES at the ESO Very Large Telescope (Paranal, Chile). Archival data were also analyzed for a few stars, sampling $\gtrsim$3 phases for each star. We obtained atmospheric parameters (T$_{\rm{eff}}$, log$g$, v$_{\rm{t}}$, and [M/H]) and abundances of several iron-peak and $α$-elements (Fe, Cr, Ni, Mg, Ca, Si, and Ti) for different pulsational phases, obtaining $$=+0.31$\pm$0.19 dex over the entire sample covering -2.2$

description: This paper considers non-backtracking random walks on random graphs generated according to the configuration model. The quantity of interest is the scaling of the mixing time of the random walk as the number of vertices of the random graph tends to infinity. Subject to mild general conditions, we link two mixing times: one for a static version of the random graph, the other for a class of dynamic versions of the random graph in which the edges are randomly rewired but the degrees are preserved. The link is provided by the probability that the random walk has not yet stepped along a previously rewired edge. We use this link to compute the scaling of the mixing time for three specific classes of random rewirings. Depending on the speed and the range of the rewiring relative to the current location of the random walk, the mixing time may exhibit no cut-off, one-sided cut-off or two-sided cut-off, a trichotomy that was also found in earlier work. Interestingly, for a class of dynamics that are `mesoscopic', i.e., non-local and non-global, we find new behaviour with six subregimes. Proofs are built on a new and flexible coupling scheme, in combination with sharp estimates on the degrees encountered by the random walk in the static and the dynamic version of the random graph. Some of these estimates require sharp control on possible short-cuts in the graph between the edges that are traversed by the random walk.

On the Global Mass Distribution in Disk Galaxies

description: We present a summary of recent assessments of the mass distribution in disk galaxies. Of issue in order to characterize galaxy formation models is to determine the relative fraction of baryons and dark matter at all radii in galaxies. For disk galaxies, various measurements of the mass distribution in galaxies based on vertical kinematics, strong lensing, residuals of scaling relations, fluid dynamical modeling, bar strength and pattern speed, warps, and others, have called for either a maximal or sub-maximal contribution of the baryons in the inner parts of the disk. We propose a global picture whereby all galaxies are typically baryon-dominated (maximal) at the center and dark-matter dominated (sub-maximal) in their outskirts. Using as a fiducial radius the peak of the rotation curve of a pure baryonic exponential disk at R_2.2=2.2 Rd, where Rd is the disk scale length, the transition from maximal to sub-maximal baryons occurs within or near R_2.2 for low-mass disk galaxies (with V_tot < 200 km/s) and beyond R_2.2 for more massive systems. The mass fraction's inverse dependence on circular velocity in disk galaxies is largely insensitive to the presence of a bar at R_2.2. The mean mass fractions of late- and early-type galaxies are shown to be different at the same fiducial radius and circular velocity, pointing to different galaxy formation mechanisms. Feedback, dynamical friction, size, and IMF variations are key ingredients for understanding these differences.

The decade of the 1990s: the lost years of opportunity for North Carolina’s ESL students
Creators: name: Shofer, Sharon LaBurt
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: Beginning in the 1980s, but gaining momentum in the 1990s, North Carolina's k-12 schools experienced a dramatic increase in the number of limited English proficient (LEP) students enrolling in schools across the state. Largely due to the unprecedented number of Latinos migrating to the state, the schools reflected the demographic patterns of this new population. Unaccustomed to linguistic diversity, the state's k-12 school systems struggled academically and economically with the new and novel demands placed on them by not only a desire to educate their LEP students, but by federal mandate. Looking to the North Carolina General Assembly for funding, k-12 school systems were denied any relief until 1999. In failing to acknowledge the looming educational crisis, politicians in the state effectively lost a decade of opportunity to fund effective English as a Second Language (ESL) programs for this new population. This lost decade of opportunity to fund ESL programs would result in negative consequences for the state's LEP k-12 students, local education agencies, and potentially North Carolina as a whole.

description: Recently, we developed the Correlation-Aided Reconstruction (CORAR) method to reconstruct solar wind inhomogeneous structures, or transients, using dual-view white-light images (Li et al. 2020; Li et al. 2018). This method is proved to be useful for studying the morphological and dynamical properties of transients like blobs and coronal mass ejection (CME), but the accuracy of reconstruction may be affected by the separation angle between the two spacecraft (Lyu et al. 2020). Based on the dual-view CME events from the Heliospheric Imager CME Join Catalogue (HIJoinCAT) in the HELCATS (Heliospheric Cataloguing, Analysis and Techniques Service) project, we study the quality of the CME reconstruction by the CORAR method under different STEREO stereoscopic angles. We find that when the separation angle of spacecraft is around 150°, most CME events can be well reconstructed. If the collinear effect is considered, the optimal separation angle should locate between 120° and 150°. Compared with the CME direction given in the Heliospheric Imager Geometrical Catalogue (HIGeoCAT) from HELCATS, the CME parameters obtained by the CORAR method are reasonable. However, the CORAR-obtained directions have deviations towards the meridian plane in longitude, and towards the equatorial plane in latitude. An empirical formula is proposed to correct these deviations. This study provides the basis for the spacecraft configuration of our recently proposed Solar Ring mission concept (Wang et al. 2020b).

Using Architectural Properties to Model and Measure Graceful Degradation

description: System-wide graceful degradation may be a viable approach to improving dependability in computer systems.  In order to evaluate and improve system-wide graceful degradation we present a system model that will explicitly define graceful degradation as a system property, and measure how well a system gracefully degrades in the presence of multiple combinations of component failures.  The system’s software architecture plays a major role in this model, because the interface and component specifications embody the architecture’s abstraction principle.  We use the architecture to group components into subsystems that enable reasoning about overall system utility.  We apply this model to an extensive example of a distributed embedded control system architecture to specify the relative utility of all valid system configurations.  We then simulate working system configurations and compare their ability to provide functionality to the utility measures predicted by our model.
The influence of wavelength, flux, and lensing selection effects on the redshift distribution of dusty, star-forming galaxies

description: We interpret the large variety of redshift distributions of galaxies found by far-infrared and (sub-)millimeter deep surveys depending on their depth and wavelength using the Béthermin et al. (2012) phenomenological model of galaxy evolution. This model reproduces without any new parameter tuning the observed redshift distributions from 100 $μ$m to 1.4 mm, and especially the increase of the median redshift with survey wavelength. This median redshift varies also significantly with the depth of the surveys, and deeper surveys do necessarily not probe higher redshifts. Paradoxically, at fixed wavelength and flux limit, the lensed sources are not always at higher redshift. We found that the higher redshift of 1.4 mm-selected south pole telescope (SPT) sources compared to other SMG surveys is not only caused by the lensing selection, but also by the longer wavelength. This SPT sample is expected to be dominated by a population of lensed main-sequence galaxies and a minor contribution ($\sim$10\%) of unlensed extreme starbursts.
