Measurement of the Spin-Orbit Misalignment of KOI-13.01 from its Gravity-Darkened Kepler Transit Lightcurve

description: We model the asymmetry of the KOI-13.01 transit lightcurve assuming a gravity-darkened rapidly-rotating host star in order to constrain the system's spin-orbit alignment and transit parameters. We find that our model can reproduce the Kepler lightcurve for KOI-13.01 with a sky-projected alignment of λ = $23 \pm 4$ degrees and with the star's north pole tilted away from the observer by $48 \pm 4$ degrees (assuming $M_* = 2.05 M_\odot$). With both these determinations, we calculate that the net misalignment between this planet's orbit normal and its star's rotational pole is $56 \pm 4$ degrees. Degeneracies in our geometric interpretation also allow a retrograde spin-orbit angle of $124 \pm 4$ degrees. This is the first spin-orbit measurement to come from gravity darkening, and is one of only a few measurements of the full (not just the sky-projected) spin-orbit misalignment of an extrasolar planet. We also measure accurate transit parameters incorporating stellar oblateness and gravity darkening: $R_* = 1.756 \pm 0.014 R_\odot$, $R_p = 1.445 \pm 0.016 R_{Jup}$, and $i = 85.9 \pm 0.4$ degrees. The new lower planetary radius falls within the planetary mass regime for plausible interior models for the transiting body. A simple initial calculation shows that KOI-13.01's circular orbit is apparently inconsistent with the Kozai mechanism having driven its spin-orbit misalignment; planet-planet scattering and stellar spin migration remain viable mechanisms. Future Kepler data will improve the precision of the KOI-13.01 transit lightcurve, allowing more precise determination of transit parameters and the opportunity to use the Photometric Rossiter-McLaughlin effect to resolve the prograde/retrograde orbit determination degeneracy.

From Regular to Strictly Locally Testable Languages

description: A classical result (often credited to Y. Medvedev) states that every language recognized by a finite automaton is the homomorphic image of a local language, over a much larger so-called local alphabet, namely the alphabet of the edges of the transition graph. Local languages are characterized by the value k=2 of the sliding window width in the McNaughton and Papert's infinite hierarchy of strictly locally testable languages (k-slt). We generalize Medvedev's result in a new direction, studying the relationship between the width and the alphabetic ratio telling how much larger the local alphabet is. We prove that every regular language is the image of a k-slt language on an alphabet of doubled size, where the width logarithmically depends on the automaton size, and we exhibit regular languages for which any smaller alphabetic ratio is insufficient. More generally, we express the trade-off between alphabetic ratio and width as a mathematical relation derived from a careful encoding of the states. At last we mention some directions for theoretical development and application.

Attitudes and preferences of consumers/purchasers toward different types of table eggs

Publisher: name: University of British Columbia
Year: 2010

description: Besides regular (white and brown) eggs, alternative types of table eggs (e.g. free-run, free-range, organic eggs) are also being sold in the Canadian market. These alternative egg types are collectively referred to as specialty eggs. The growth rate of the specialty eggs market has been high during the last decade in British Columbia (BC). Despite this growth there is insufficient information concerning consumers/purchasers’ attitudes and preferences relating to this differentiated egg market. The objectives of this research were: 1) to identify the consumers’ attitudes, preferences and socio-demographic characteristics towards different types of table eggs, and 2) to determine the target market for six types of eggs and to investigate the relative importance of factors (e.g. price, environmental concerns) affecting the purchase of different types of eggs. An online survey was the primary research tool used to gather data for this project. Potential subjects were randomly selected from a list of email addresses from BC residents and 702 completed surveys were processed. Our results indicated that the purchase of cage-free eggs was significantly higher in BC in 2009 than a 2007 Print Measurement Bureau consumer survey. Respondents with a higher educational level and higher income consumed more free-range eggs and less white regular eggs than respondents with a lower educational level. Respondents who were more concerned about local production and bird welfare purchased more free-run, free-range and organic eggs, whereas for purchasers of regular eggs, price was more important. Size of the household influenced the type of purchased eggs. Respondents from bigger households purchased proportionally more white regular eggs. Respondents who used fewer alternative egg types recognized the nutritional value of white regular eggs being as high as the free-run, free-range and organic eggs. Respondents who purchased different types of eggs have different priorities. The results indicated that there are potential benefits to be gained from a marketing mix plan designed to develop the market share of different types of eggs in the future.

description: Intermediate mass protostars, the bridge between the very common solar-like protostars and the more massive, but rarer, O and B stars, can only be studied at high physical spatial resolutions in a handful of clouds. In this paper we present and analyze the continuum results from an observing campaign at the Submillimeter Array targeting two well-studied intermediate mass protostars in Orion, NGC 2071 and L1641 S3 MMS 1. The extended SMA (eSMA) probes structure at angular resolutions up to 0.2", revealing protostellar disks on scales of 200 AU. Continuum flux measurements on these scales indicate that a significant amount of mass, a few tens of M{\odot}, are present. Envelope, stellar, and disk masses are derived using both compact, extended and eSMA configurations and compared against SED-fitting models. We hypothesize that fragmentation into three components occurred within NGC 2071 at an early time, when the envelopes were less than 10% of their current masses, e.g. < 0.5 M{\odot}. No fragmentation occurred for L1641 S3 MMS 1. For NGC 2071 evidence is given that the bulk of the envelope material currently around each source was accreted after the initial fragmentation. In addition, about 30% of the total core mass is not yet associated to one of the three sources. A global accretion model is favored and a potential accretion history of NGC 2071 is presented. It is shown that the relatively low level of fragmentation in NGC 2071 was stifled compared to the expected fragmentation from a Jean's argument.

Quantification of the volume-fraction reduction of sheared fragile glass-forming liquids and its impact on rheology

Publisher: name: arXiv
Year: 2024
Subjects: subject: Soft Condensed Matter (cond-mat.soft)
subject: FOS: Physical sciences

description: This study determines the volume-fraction reduction of sheared fragile glass-forming liquids. We consider a group of hypothetical systems that consist of particles with anisotropic particle-size modulations yet have almost the same average particle configuration as actual systems under shear flow. Our molecular dynamics (MD) simulations demonstrate that one specific hypothetical system can reproduce the relaxation dynamics of an actual sheared system, and we identify the shear-flow effect on the particle size with anisotropic size-modulation of this specific system. Then, based on the determination of the particle size and the resultant volume fraction, we rationalize how slight decreases in the volume fraction significantly reduce the viscosity snf provide a nonlinear constitutive equation. Notably, the obtained rheological predictions, including the crossover shear rate from Newtonian to non-Newtonian behavior, can be expressed only in terms of experimental observables, showing a good agreement with the MD simulation results. Our perspective on the volume fraction under shear flow may provide new insights into the conventional concept of free-volume.

description: Light is a crucial management factor in birds as it affects production efficiency, physiological and behavioural response of poultry. The reproductive performance of the laying hen is dependent on the duration, intensity and quality of light used during housing. This makes the use of artificial lighting programmes in modern poultry houses for maintaining egg production. In addition to the impacts on behavioural output, light wavelength also influences fear and stress levels due to release of oxygen free radicals.
Hidden symmetries of Eisenhart-Duval lift metrics and the Dirac equation with flux

description: The Eisenhart-Duval lift allows embedding non-relativistic theories into a Lorentzian geometrical setting. In this paper we study the lift from the point of view of the Dirac equation and its hidden symmetries. We show that dimensional reduction of the Dirac equation for the Eisenhart-Duval metric in general gives rise to the non-relativistic Levy-Leblond equation in lower dimension. We study in detail in which specific cases the lower dimensional limit is given by the Dirac equation, with scalar and vector flux, and the relation between lift, reduction and the hidden symmetries of the Dirac equation. While there is a precise correspondence in the case of the lower dimensional massive Dirac equation with no flux, we find that for generic fluxes it is not possible to lift or reduce all solutions and hidden symmetries. As a by-product of this analysis we construct new Lorentzian metrics with special tensors by lifting Killing-Yano and Closed Conformal Killing-Yano tensors and describe the general Conformal Killing-Yano tensor of the Eisenhart-Duval lift metrics in terms of lower dimensional forms. Lastly, we show how dimensionally reducing the higher dimensional operators of the massless Dirac equation that are associated to shared hidden symmetries it is possible to recover hidden symmetry operators for the Dirac equation with flux.

description: Instant e-Teaching is a new concept that supplements e-Teaching and e-Learning environment in providing a full and comprehensive modern education styles. The e-Learning technology depicts the concept of enabling self-learning among students on a certain subject using online reference and materials. While the instant e-teaching requires 'face-to-face' characteristic between teacher and student to simultaneously execute actions and gain instant responses. The word instant enhances the e- Teaching with the concept of real time teaching. The challenge to exercise online and instant teaching is not just merely relying on the technologies and system efficiency, but it needs to satisfy the usability and friendliness of the system as to replicate the traditional class environment during the deliveries of the class. For this purpose, an instant e-Teaching framework is been developed that will emulate a dedicated virtual classroom, and primarily designed for synchronous and live sharing of current teaching notes. The model has been demonstrated using a teaching Arabic recitation prototype and evaluated from the professional user profession's perspectives.

description: Die globalen Stoff- und Energiekreisläufe sind zu einem immensen Teil beeinflusst durch die Prozesse der Tiefsee. In diesem Ökosystem bilden prokaryotische Lebensformen den größten Teil der Biomasse, wobei Bakterien für den Großteil des Abbaus von Rohöl bei Ölkatastrophen, wie der Deepwater Horizon Katastrophe 2010, verantwortlich sind. In den meisten Studien zu Rohölabbau durch Bakterien wurde der hydrostatische Druck der Tiefsee als Einflussfaktor vernachlässigt. Diese Dissertation untersuchte die Veränderungen in der Bakteriengemeinschaftsstruktur durch den Einfluss von Rohöl, Dispergenzien und Druck. Weiterführende Experimente mit rohölabbauenden Bakterienstämmen konnten die speziesspezifischen Reaktionen auf Druck und Dispergenzien zeigen.
description: The oceans deep sea ecosystem is an important driver of the global energy and element cycling, where prokaryotic cells represent the largest portion of the biomass. The role of bacteria in remediation of accidentally spilled crude oil, such as the Deepwater Horizon disaster in 2010, is prevailing. So far, most studies on the hydrocarbon degradation by bacteria neglected the hydrostatic pressure of the deep sea. This thesis investigated bacterial community structure changes induced by hydrocarbon input, such as crude oil or dispersing agent and hydrostatic pressure. Further experiments on hydrocarbon degrading single strain showed the species-specific responses to pressure and the addition of dispersant.

description: Auf einen Blick...

In einer dynamischen Wirtschaft sind Entlassungen und Neueinstellungen wichtige Mittel, auf veränderlichen Arbeitskräftebedarf zu reagieren. Ein Wiedereinstieg nach erfolgter Entlassung gilt für Ältere als schwierig, ist aber angesichts verlängerter Erwerbsphasen oftmals nötig.
Anders als die Zahl der älteren Erwerbstätigen ist die Zahl der Älteren ab 50 bis unter 65 Jahren, die neu eingestellt wurden, in den letzten Jahren nicht stetig gestiegen. Im Jahr 2009 lag sie aber mit über 850.000 Personen deutlich über dem Tiefpunkt von 2006, als es nur ca. 600.000 Personen waren. Der Anteil der neu eingestellten Älteren an allen neu Eingestellten lag mit 13 Prozent nur halb so hoch wie der Anteil der beschäftigten Älteren an allen sozialversicherungspflichtig Beschäftigten (26 Prozent, 2009).
Mit steigendem Alter treten immer weniger Personen eine neue Stelle an. Dieser Alterseffekt trifft besonders die Geringqualifizierten. Ältere Hochqualifizierte, von denen im letzten Drittel der Erwerbsphase nur vergleichsweise wenige neu eingestellt werden, profitieren von stabilen Beschäftigungsverhältnissen, aufgrund derer sie seltener eine neue Beschäftigung suchen.
Die Altersselektivität bei Einstellungen – gemessen als Verhältnis der Eintrittsraten jüngerer und älterer neu eingestellter Mitarbeiter – ist seit Jahren unverändert. Dies deutet darauf hin, dass sich das betriebliche Rekrutierungsverhalten gegenüber älteren Bewerbern nicht geändert hat. Lediglich in der sehr kleinen Gruppe der 60- bis unter 65-Jährigen zeichnet sich in den letzten Jahren eine Verbesserung ab, ohne dass aber das Niveau der 55- bis 59-Jährigen erreicht wird.
Die Alterserwerbsbeteiligung ließe sich über die bereits erzielten Zuwächse hinaus vermutlich beträchtlich steigern und die Erwerbsphasen entsprechend verlängern, wenn die Betriebe ihre Personalpolitik dem demographischen Wandel anpassten und ältere Bewerber stärker als bisher berücksichtigten.

description: Here we show a direct mapping between waveguide theory and spin chain transport, opening an alternative approach to quantum information transport in the solid-state. By applying temporally varying control profiles to a spin chain, we design a virtual waveguide or 'spin-guide' to conduct individual spin excitations along defined space-time trajectories of the chain. We explicitly show that the concepts of confinement, adiabatic bend loss and beamsplitting can be mapped from optical waveguide theory to spin-guides (and hence 'spin-splitters'). Importantly, the spatial scale of applied control pulses is required to be large compared to the inter-spin spacing, and thereby allowing the design of scalable control architectures.

description: Context: Convergent point (CP) search methods are important tools for studying the kinematic properties of open clusters and young associations whose members share the same spatial motion. Aims: We present a new CP search strategy based on proper motion data. We test the new algorithm on synthetic data and compare it with previous versions of the CP search method. As an illustration and validation of the new method we also present an application to the Hyades open cluster and a comparison with independent results. Methods: The new algorithm rests on the idea of representing the stellar proper motions by great circles over the celestial sphere and visualizing their intersections as the CP of the moving group. The new strategy combines a maximum-likelihood analysis for simultaneously determining the CP and selecting the most likely group members and a minimization procedure that returns a refined CP position and its uncertainties. The method allows one to correct for internal motions within the group and takes into account that the stars in the group lie at different distances. Results: Based on Monte Carlo simulations, we find that the new CP search method in many cases returns a more precise solution than its previous versions. The new method is able to find and eliminate more field stars in the sample and is not biased towards distant stars. The CP solution for the Hyades open cluster is in excellent agreement with previous determinations.

description: High-velocity halo stars provide important information about the properties of the extreme Galactic halo. The study of unbound and bound Population II stars permits us to better estimate the mass of the halo.} {We carried out a detailed spectroscopic and kinematic study and have significantly refined the distance and the evolutionary state of the star. Its atmospheric parameters, chemical abundances and kinematical properties were determined using high-resolution optical spectroscopy and employing the local-thermodynamic-equilibrium model atmospheres of Kurucz and the spectral analysis code {\sc moog}. We found that CD-62$\degr$1346 is a metal-poor ([Fe/H]=$-$1.7) evolved giant star with $T_{\rm eff}=5300$ K and $\log g=1.7$. The star exhibits high carbon and s-element abundances typical of CH stars. It is also a lead star. Our kinematic analysis of its 3D space motions shows that this star has a highly eccentric ($e=0.91$) retrograde orbit with an apogalactic distance of $\sim 100$ kpc, exceeding by a factor of three the distance to the Magellanic Clouds. The star travels with very high velocity relative to the Galactocentric reference frame ($V_{\rm GRF}=570$ km\,s$^{-1}$). CD-62$\degr$1346 is an evolved giant star and not a subgiant star, as was considered earlier. Whether it is bound or unbound to the Galaxy depends on the assumed mass and on the adopted Galactic potential. We also show that the star HD 5223 is another example of a high-velocity CH star that exceeds the Galactic escape velocity. Possible origins of these two high-velocity stars are briefly discussed. CD-62$\degr$1346 and HD 5223 are the first red giant stars to join the restricted group of hypervelocity stars.

description: We present the results of a comprehensive analysis of the structure and kinematics of six Galactic globular clusters. By comparing the results of the most extensive photometric and kinematical surveys available to date with suited dynamical models, we determine the stellar and dynamical masses of these stellar systems taking into account for the effect of mass segregation, anisotropy and unresolved binaries. We show that the stellar masses of these clusters are on average smaller than those predicted by canonical integrated stellar evolution models because of the shallower slope of their mass functions. The derived stellar masses are found to be also systematically smaller than the dynamical masses by ~40%, although the presence of systematics affecting our estimates cannot be excluded. If confirmed, this evidence can be linked to an increased fraction of retained dark remnants or to the presence of a modest amount of dark matter.

description: The ever increasing demands for using resource-constrained mobile devices for running more resource intensive applications nowadays has initiated the development of cyber foraging solutions that offload parts or whole computational intensive tasks to more powerful surrogate stationary computers and run them on behalf of mobile devices as required. The choice of proper mix of mobile devices and surrogates has remained an unresolved challenge though. In this paper, we propose a new decision-making mechanism for cyber foraging systems to select the best locations to run an application, based on context metrics such as the specifications of surrogates, the specifications of mobile devices, application specification, and communication network specification. Experimental results show faster response time and lower energy consumption of benched applications compared to when applications run wholly on mobile devices and when applications are offloaded to surrogates blindly for execution.

description: We consider the behaviour of bipartite and tripartite non-locality between fermionic entangled states shared by observers, one of whom uniformly accelerates. We find that while fermionic entanglement persists for arbitrarily large acceleration, the Bell/CHSH inequalities cannot be violated for sufficiently large but finite acceleration. However the Svetlichny inequality, which is a measure of genuine tripartite non-locality, can be violated for any finite value of the acceleration.

description: In this work I study the relation between the geometric properties of a graph G and the eigenvalues of its adjacency matrix A(G). We show that it is possible to make use of "the spectral theory of graphs" in order to identify certain properties of a graph. For example from the eigenvalues of G we are able to decide whether or not G is regular, bipartite, without triangles.
Functional regulation of N-methyl-D-aspartate receptor subtypes and their involvement in hippocampal plasticity

description: Regulation of NMDAR activity by desensitization is important in physiological and pathological states. We previously reported that desensitization decreases during hippocampal neuronal development, correlating with NMDAR composition, synaptic localization and association with PSD-95. To determine if PSD-95-induced changes in NMDAR desensitization occur because of direct binding to NR2 subunits or due to recruitment of regulatory proteins, we tested the effects of various PSD-95 constructs on NMDAR currents in HEK293 cells and neurons. In HEK cells, wt PSD-95 significantly reduced wt NMDAR desensitization without altering currents of NMDARs containing NR2A-S1462A, a mutation that abolishes PSD-95 binding. Moreover, PDZ1-2 domain was sufficient for this effect in neurons with low endogenous PSD-95 levels. Moreover, other PSD-95 family members with highly homologous PDZ1-2 domains significantly reduced NMDAR desensitization. In mature neurons, disruption of PSD-95/NMDAR interaction through PKC activation, or through interference peptides, increased desensitization to levels found in immature neurons. We conclude that direct binding of PSD-95 increases stability of NMDAR responses to agonist exposure. Desensitization is a property that shapes synaptic responses, and modulates the calcium signal mediated by the two predominant NMDARs subtypes in hippocampus, with possible consequences for their functioning. Further, we examined the involvement of NR2 subtypes in synaptic plasticity in hippocampal dentate gyrus of juvenile mice. Exercise was used as a means to alter expression of the NR2 subunits in this region. We compared two groups of animals: Controls, which were housed in conditions of minimal enrichment, and iii Runners, which had access to an exercise wheel. NMDAR-dependent LTP expression was significantly greater in Runners than in Controls; in the presence of NR2B subunit antagonists, it was significantly reduced in both groups. NR2A subunit antagonist blocked LTP in slices from Runners and produced a slight depression in Control animals. LTD could not be prevented by either of the NR2B specific antagonists. Strikingly, eliminating NR2A subunit-containing receptor activity prevented LTD in Runners, but not in Control animals. Overall, these results indicate that interplay between subtype, subcellular localization and size of NMDAR subpopulations accounts for their diverse role in synaptic plasticity induction, and that exercise increases the contribution of NR2A to plasticity.

description: This contribution is devoted to the study of positional numeration systems with negative base introduced by Ito and Sadahiro in 2009, called (-β)-expansions. We give an admissibility criterion for more general case of (-β)-expansions and discuss the properties of the set of (-β)-integers. We give a description of distances within this set and show that this set can be coded by an infinite word over an infinite alphabet, which is a fixed point of a non-erasing non-trivial morphism.
