Making connections in Horseshoe Bay
Creators: name: Thompson, David B.
Publisher: name: University of British Columbia
Year: 2009

description: Horseshoe Bay, British Columbia is: 1) a geographically constricted waterfront neighbourhood of the Municipality of West Vancouver, 2) a north facing deep water ocean bay with a history of marine access and activities, 3) the site of one of the busiest terminals on the British Columbia Ferry Corporation system with 2.6 million vehicles and 7 million passengers per year. The ferry corporation is planning to expand the vehicle holding lots and administration facilities in 2001 and there are public concerns about possible degradation of the character and environment of the community. The Municipality of West Vancouver has expressed a desire to rebuild the foreshore embankment of the waterfront in Horseshoe Bay Park and upgrade the various amenities. Merchants of Horseshoe Bay are concerned that changes to the pedestrian access from the ferry terminal lots may negatively affect their business. The federal government is in the midst of divesting itself of ownership and responsibility for the public wharf. These are the issues and factors that were considered in a project where several different landscape locations with different functions within the Horseshoe Bay community were the subject of a redesign program. The proposed interventions range from environmental graphics to intertidal infill and wetland construction. Each of the various proposals has a different focus, use or function but all share the common theme of landscape connectivity, linking the community to the environment in a mutually beneficial way.

description: The role of intrinsic $k_\perp$ in semi-inclusive Deep Inelastic Scattering (SIDIS) processes ($l p \to l h X$) is studied with exact kinematics within QCD parton model at leading order; the dependence of the unpolarized cross section on the azimuthal angle between the leptonic and the hadron production planes (Cahn effect) is compared with data and used to estimate the average values of $k_\perp$ both in quark distribution and fragmentation functions. The resulting picture is applied to the description of the weighted single spin asymmetry $A_{UT}^{\sin(ϕ_π- ϕ_S)}$ recently measured by the HERMES collaboration at DESY; this allows to extract parameters for the quark Sivers functions. The extracted Sivers functions give predictions for the COMPASS measurement of $A_{UT}^{\sin(ϕ_π- ϕ_S)}$ in agreement with recent data, while their contribution to HERMES $A_{UL}^{\sinϕ_π}$ is computed and found to be small. Predictions for $A_{UT}^{\sin(ϕ_K - ϕ_S)}$ for kaon production at HERMES are also given.

description: We introduce a class of functions that limit to multifractal measures and which arise when one takes the Fourier transform of the Hadamard transform. This introduces generalizations of the Fourier transform of the well-studied and ubiquitous Thue-Morse sequence, and introduces also generalizations to other intriguing sequences. We show their relevance to quantum chaos, by displaying quantum eigenfunctions of the quantum bakers map that are approximated well by such measures, thereby extending our recent work where we pointed to the existence of ``Thue-Morse'' states.

description: Obwohl digitaler Textverarbeitung heutzutage eine enorme Bedeutung zukommt und die Vermittlung entsprechender Kompetenzen in Deutschland, Österreich und der Schweiz curricular verankert ist, bilden empirisch fundierte Konzepte zum Tastaturschreiben im deutschsprachigen Raumweitgehend ein Desiderat. International liegen jedoch Studien vor, die belegen, dass eine gezielte Förderung die Tastaturschreibfertigkeiten erhöhen und positive Effekte auf Rechtschreibung und Textproduktion haben kann. An diesen Ergebnissen setzt das D-A-CH-Projekt Didaktik des Tastaturschreibens und der Textverarbeitung (TasDi) an: Es zielt im Kern darauf, Lernmodule für das Tastaturschreiben zu entwickeln und zu evaluieren, die auf evidenzbasierten Erkenntnissen der Schreib- und Rechtschreibdidaktik aufbauen. Die länderübergreifende Perspektive ist aufschlussreich, da die schulische Implementierung des Tastaturschreibens im D-A-CH-Raum unterschiedlich fortgeschritten ist. In der ersten Phase des Projekts, die im Beitrag im Zentrum steht, erfolgt u.a. eine Analyse existierender Tastaturschreiblehrgänge. Diese zeigt, dass bisherige Lehrgänge v.a. an schreibmotorischen Prinzipien orientiert sind und durch eine schreib- und rechtschreibdidaktische Profilierung profitieren können.

description: We consider the model giving rise to Witten's superconducting cosmic strings at finite fermion chemical potential and temperature. We demonstrate how various symmetries of the hamiltonian can be used to exactly compute the fermion electric current in the string background. We show that the current along the string is not sensitive to the profiles of the string fields, and at fixed chemical potential and temperature depends only on the string winding number, the total gauge flux through the vortex and, possibly, the fermion mass at infinity.

description: Over the past few decades, information communication technology (ICT) and Internet interaction has developed drastically, causing more companies to join the phenomenon of Bricks and Mortar business model. Furthermore, as the trend persists, new business models have appeared: social networking sites, those who support online interaction and communication among the peers (such as Facebook and Twitter), email services and behavioral advertisement, electronic commerce for more convenient shopping experience, and information mediation online corporations, those who reduce individual search cost (such as online travel agency, OTA). Here, many times these corporations are not transparent in information and terms of use. If users do not agree to sometimes unfair statements, users are not permitted to use the service, which does not leave many choices for the users. This is much like the act of monopoly only except that it is overruling information instead of price. In order to combat this, we recall our traditional business model: competition brings about equilibrium in the market. In this research, we are going to investigate the fair terms of use and information transparency of online websites.

description: The entropy of a BTZ black hole in the presence of gravitational Chern-Simons terms has previously been analyzed using Euclidean action formalism. In this paper we treat the BTZ solution as a two dimensional black hole by regarding the angular coordinate as a compact direction, and use Wald's Noether charge method to calculate the entropy of this black hole in the presence of higher derivative and gravitational Chern-Simons terms. The parameters labelling the black hole solution can be determined by extremizing an entropy function whose value at the extremum gives the entropy of the black hole.

description: This research helped to isolate and identify Lactic Acid Bacteria with potent antimicrobial properties exhibiting greater inhibition against different foodborne pathogens. These LAB could be used as a bio-preservatives in many dairy products instead of chemical preservatives, and could protect public health and reduce the incidence of foodborne pathogens and spoilage microorganisms in different food products. Similarly, these LAB could be used as an alternative to antibiotics to treat many diseases due to their beneficial antimicrobial properties and could mitigate the problem of increased antibiotic resistance in bacteria due to overuse or misuse of antibiotics.

description: Road intersections data have been used across different geospatial applications and analysis. The road network datasets dating from pre-GIS years are only available in the form of historical printed maps. Before they can be analyzed by a GIS software, they need to be scanned and transformed into the usable vector-based format. Due to the great bulk of scanned historical maps, automated methods of transforming them into digital datasets need to be employed. Frequently, this process is based on computer vision algorithms. However, low conversion accuracy for low quality and visually complex maps and setting optimal parameters are the two challenges of using those algorithms. In this paper, we employed the standard paradigm of using deep convolutional neural network for object detection task named region-based CNN for automatically identifying road intersections in scanned historical USGS maps of several U.S. cities. We have found that the algorithm showed higher conversion accuracy for the double line cartographic representations of the road maps than the single line ones. Also, compared to the majority of traditional computer vision algorithms RCNN provides more accurate extraction. Finally, the results show that the amount of errors in the detection outputs is sensitive to complexity and blurriness of the maps as well as the number of distinct RGB combinations within them.

On the origin of the circular polarization in radio pulsars

Publisher: name: arXiv
Year: 2005

description: Properties of circularly polarized waves are studied in the pulsar magnetosphere plasma. It is shown that some observational characteristics of the circular polarization observed in the pulsar radio emission can be qualitatively explained in the framework of the model based on anomalous Doppler resonance. Performed analysis provides that if the difference between Lorentz factors of electrons and positrons is relatively high, one of the circularly polarized waves becomes super-luminal and therefore can not be generated by cyclotron instability. We suggest that this case corresponds to the pulsars with the domination of one hand of circular polarization through the whole averaged pulse profile at all observed frequencies. For intermediate values of the difference between Lorentz factors both circularly polarized waves are generated, but the waves of one handness are much more effectively generated for high frequencies, whereas generation of another handness dominates for low frequencies. This should correspond to the pulsars with strong frequency dependence of the degree of circular polarization. The case of relatively small difference between Lorentz factors corresponds to the pulsars with sign reversal of the circular polarization in the centre of averaged pulse profiles.

description: We present the I-band luminosity function of the differentially reddened globular cluster M10. We combine photometric analysis derived from wide-field (23' x 23') images that include the outer regions of the cluster and high-resolution images of the cluster core. After making corrections for incompleteness and field star contamination, we find that the relative numbers of stars on the lower giant branch and near the main-sequence turnoff are in good agreement with theoretical predictions. However, we detect significant (> 6 σ) excesses of red giant branch stars above and below the red giant branch bump using a new statistic (a population ratio) for testing relative evolutionary timescales of main-sequence and red giant stars. The statistic is insensitive to assumed cluster chemical composition, age, and main-sequence mass function. The excess number of red giants cannot be explained by reasonable systematic errors in our assumed cluster chemical composition, age, or main-sequence mass function. Moreover, M10 shows excesses when compared to the cluster M12, which has nearly identical metallicity, age, and color-magnitude diagram morphology. We discuss possible reasons for this anomaly, finding that the most likely cause is a mass function slope that shows significant variations as a function of mass.

description: From the moment atomic precision control of the growth process of graphene was achieved, more elaborated carbon allotropes were proposed opening new channels for flat optoelectronics at the nanoscale. A special type of this material presenting a V-shape (or "kinked" pattern) was recently synthesized and named Chevron-graphene nanoribbons (C-GNRs). To realize the reach of C--GNRs in developing new applications, the formation, and transport of charge carriers in their lattices should be primarily understood. Here, we investigate the static and dynamical properties of quasiparticles in C-GNRs. We study the effects of electron-phonon coupling and doping on the system. We also determine the kind of charge carriers present in C--GNR. It is observed that a phase transition occurs between a delocalized regime of conduction and regimes mediated by charge carriers. Such a phase transition is highly dependent on the doping concentration. Remarkably, crucial differences from the transport in standard graphene nanoribbons are identified. These factors are noted to have a profound impact on the mobility on the system which, in turn, should decisively impact the performance of electronic devices based on C-GNRs.

description: Vertical movement of zirconia-yttria stabilized 2 mm balls is measured by a laser facility at the surface of a vibrated 3D granular matter under gravity. Realizations z(t) are measured from the top of the container by tuning the fluidized gap with a 1D measurement window in the direction of the gravity. The statistics obeys a Fermi-like configurational approach which is tested by the relation between the dispersions in amplitude and velocity. We introduce a generalized equipartition law to characterize the ensemble of particles which cannot be described in terms of a Brownian motion. The relation between global granular temperature and the external excitation frequency is established.

description: Quantum mechanics clearly violates the weak equivalence principle (WEP). This implies that quantum mechanics also violates the strong equivalence principle (SEP), as shown in this paper. Therefore a theory of quantum gravity may not be possible unless it is not based upon the equivalence principle, or if quantum mechanics can change its mass dependence. Neither of these possibilities seem likely at the present time. Examination of QM in n-space, as well as relativistic QM equations does not change this conclusion.

description: The dynamics of a spatially extended system of two competing species in the presence of two noise sources is studied. A correlated dichotomous noise acts on the interaction parameter and a multiplicative white noise affects directly the dynamics of the two species. To describe the spatial distribution of the species we use a model based on Lotka-Volterra (LV) equations. By writing them in a mean field form, the corresponding moment equations for the species concentrations are obtained in Gaussian approximation. In this formalism the system dynamics is analyzed for different values of the multiplicative noise intensity. Finally by comparing these results with those obtained by direct simulations of the time discrete version of LV equations, that is coupled map lattice (CML) model, we conclude that the anticorrelated oscillations of the species densities are strictly related to non-overlapping spatial patterns.

description: Morphologies of urban patterns display multifractal scaling. However, what data should be used to represent an urban pattern and its scaling? Here, we calculated Renyi's generalized dimensions (RGD) spectra using data corresponding to different urban modalities including urban land cover, urban impervious surface, population density, and street intersection points. All data are circa 2010 and we calculated their RGD spectra in six urbanized areas located across the United States. We calculated the RGD spectra by using Hill's numbers rather than statistical moments which leads to a clear interpretation of generalized dimensions and to spatial visualization of pattern's multifractality. The results show that patterns of different urban modalities in a given urbanized area are characterized by different RGD spectra and thus have different morphologies. In our six examples, we found that morphologies of patterns of land cover and impervious surface tend to be monofractal, patterns of street intersection points tend to be moderately multifractal, and patterns of population density tend to be strongly multi-fractal. Spatial visualization supporting this numerical finding is provided. Thus, when studying the multifractality of urban morphology, it is important to choose a modality that is appropriate to the goal of the investigation. Urban areas may have similar morphologies on the basis of one modality but dissimilar on the basis of another. We have found that two out of our six urban areas have similar morphologies on the basis of all four modalities.

description: The thesis explores the impact of hybrid work on cooperation between employees to achieve an organisation's cooperative purpose and individual self-interest. Taking an interdisciplinary approach using evolutionary psychology and sociology, the study found that an individual's role, the complexity of information and their professional and personal interests were vital to understanding their choice of working from home (WFH) and from the office (WFO) and their willingness to build social workplace relationships and cooperate. Understanding the interplay between these factors and their impact on cooperative outcomes will aid management in providing an optimum balance between WFH and WFO.

description: Industrial water demand in the state of Pennsylvania is anticipated to increase in the near future due to the expansion of hydraulic fracturing of the Marcellus Shale. Penn- sylvania’s water markets are increasingly operated by investor-owned water monopolies, and have prices regulated by the Pennsylvania Utility Commission (PUC). The PUC’s decisions on whether to approve or deny changes in the price of water can take up to nine months. This thesis estimates the quantity of deadweight loss attributable to this regulatory lag in Pennsylvania’s water markets in a scenario of increasing demand. In this work, the model for a natural monopoly facing a price ceiling is defined, followed by an estimation of the relevant cost and revenue curves for a representative Pennsylvania water monopoly, after which residential and commercial water demand were estimated, with deadweight losses then being calculated. Demand is then increased such that mar- ket price would exceed the PUC-approved maximum price, which is then charged while the hearing and petitioning process occurs. This analysis calculates increases in esti- mated deadweight loss of 92.83% for the residential water market, and 40.46% for the commercial market. This finding indicates that if maintaining market efficiency is a goal for the PUC, this commission should aim to respond as dynamically as possible to changing market conditions when regulating monopoly water pricing.

description: The absence of the single-photon nonlinearity has been a major roadblock in developing quantum photonic circuits at optical frequencies. In this paper, we demonstrate a periodically-poled thin film lithium niobate microring resonator (PPLNMR) that reaches 5,000,000%/W second harmonic conversion efficiency---almost 20-fold enhancement over the state-of-the-art---by accessing its largest $χ^{(2)}$ tensor component $d_{33}$ via quasi-phase matching. The corresponding single photon coupling rate $g/2π$ is estimated to be 1.2 MHz, which is an important milestone as it approaches the dissipation rate $κ/2π$ of best available lithium niobate microresonators developed in the community. Using a figure of merit defined as $g/κ$, our devices reach a single photon nonlinearity approaching 1%. We show that, by further scaling of the device, it is possible to improve the single photon nonlinearity to a regime where photon-blockade effect can be manifested.
Gravitational field equations in a braneworld with Euler-Poincare term

description: We present the effective gravitational field equations in a 3-brane world with Euler-Poincare term and a cosmological constant in the bulk spacetime. The similar equations on a 3-brane with $\mathbb{Z}_2$ symmetry embedded in a five dimensional bulk spacetime were obtained earlier by Maeda and Torii using the Gauss-Coddazzi projective approach in the framework of the Gaussian normal coordinates. We recover these equations on the brane in terms of differential forms and using a more general coordinate setting in the spirit of Arnowitt, Deser and Misner (ADM). The latter allows for acceleration of the normals to the brane surface through the lapse function and the shift vector. We show that the gravitational effects of the bulk space are transmitted to the brane through the projected ``electric'' 1-form field constructed from the conformal Weyl curvature 2-form of the bulk space. We also derive the evolution equations into the bulk space for the electric 1-form field, as well as for the ``magnetic'' 2-form field part of the bulk Weyl curvature 2-form. As expected, unlike on-brane equations, the evolution equations involve terms determined by the nonvanishing acceleration of the normals in the ADM-type slicing of spacetime.

description: Drifters designed to mimic floating marine debris and small patches of pelagic \emph{Sargassum} were satellite tracked in four regions across the North Atlantic. Though subjected to the same initial conditions at each site, the tracks of different drifters quickly diverged after deployment. We explain the clustering of drifter types using a recent Maxey-Riley theory for surface ocean inertial particle dynamics applied on multidata-based mesoscale ocean currents and winds from reanalysis. Simulated trajectories of objects at the air-sea interface are significantly improved when represented as inertial (accounting for buoyancy and size), rather than as perfectly Lagrangian (fluid following) particles. Separation distances between simulated and observed trajectories were substantially smaller for debris-like drifters than for \emph{Sargassum}-like drifters, suggesting that additional consideration of its physical properties relative to fluid velocities may be useful. Our findings can be applied to model variability in movements and distribution of diverse objects floating at the ocean surface.

Synthesis of N-phenethylnorhydromorphone : a hydromorphone analogue
Creators: name: Lo, Karen
Publisher: name: University of British Columbia
Year: 2009

description: Since its clinical introduction in 1926, hydromorphone (7) has been used in the treatment of moderate to severe pain. Hydromorphone (7) is a semi-synthetic congener of morphine (1), and it has a relative analgesic potency of 5 to 1 compared to its parent compound 1. It has been shown from previous structure-activity relationships on opioid analgesics that when a peripheral group on the molecule is modified, the analgesic activity of the molecule is altered. Specifically, the substitution of a phenethyl moiety for the methyl group on the basic nitrogen of opioid analgesics produces an increase in analgesic activity. For example, fentanyl (27), which is part of the piperidine group of analgesics, is found in rats to be 300 times more potent than morphine (1), the gold standard for comparative effects between opioid analgesics. To date, the N-phenethyl derivative 20 of hydromorphone has not been synthesized. As such, the purpose of this study was to synthesize N-phenethylnorhydromorphone (20); and ultimately to test the analgesic activity of 20 in the rat model. We hypothesized that the direct alkylation of norhydromorphone (17) with an alkyl halide via an SN2 reaction mechanism would be an effective route for the synthesis of N-phenethylnorhydromorphone (20). Although the chemical method proved to be effective in producing the desired compound 20, it was not efficient, producing a low yield of 1.3%. The identity of compound 20 was confirmed by high-performance liquid chromatography-tandem mass spectrometry, infrared spectroscopy, and 1H NMR analysis, both one-dimensional and two-dimensional. In conclusion, an alternate approach towards the synthesis of compound 20 will need to be examined in order to improve the productive yield, such that more product will be available for further studies on the analgesic activity of N-phenethylnorhydromorphone (20).

description: The ideal free distribution (IFD) has been used to predict the distribution of foraging animals in a wide variety of systems. However, its predictions do not always match observed distributions of foraging animals. Instead, we often observe that there are more consumers than predicted in low-quality patches and fewer consumers than predicted in high-quality patches (i.e. undermatching). We examine the possibility that animal personality is one explanation for this undermatching. We first conducted a literature search to determine how commonly studies document the personality distribution of populations. Second, we created a simple individual-based model to conceptually demonstrate why knowing the distribution of personalities is important for studies of populations of foragers in context of the IFD. Third, we present a specific example where we calculate the added time to reach the IFD for a population of mud crabs that has a considerable number of individuals with relatively inactive personalities. We suggest that animal personality, particularly the prevalence of inactive personality types, may inhibit the ability of a population to track changes in habitat quality, therefore leading to undermatching of the IFD. This may weaken the IFD as a predictive model moving forward.

description: We present Atacama Large Millimeter/submillimeter Array (ALMA) 1.3 mm observations of four young, eruptive star-disk systems at 0.4" resolution: two FUors (V582 Aur and V900 Mon), one EXor (UZ Tau E) and one source with an ambiguous FU/EXor classification (GM Cha). The disks around GM Cha, V900 Mon and UZ Tau E are resolved. These observations increase the sample of FU/EXors observed at sub-arcsecond resolution by 15%. The disk sizes and masses of FU/EXors objects observed by ALMA so far suggest that FUor disks are more massive than Class 0/I disks in Orion and Class II disks in Lupus of similar size. EXor disks in contrast do not seem to be distinguishable from these two populations. We reach similar conclusions when comparing the FU/EXor sample to the Class I and Class II disks in Ophiuchus. FUor disks around binaries are host to more compact disks than those in single-star systems, similar to non-eruptive young disks. We detect a wide-angle outflow around GM Cha in $^{12}$CO emission, wider than typical Class I objects and more similar to those found around some FUor objects. We use radiative transfer models to fit the continuum and line data of the well-studied disk around UZ Tau E. The line data is well described by a keplerian disk, with no evidence of outflow activity (similar to other EXors). The detection of wide-angle outflows in FUors and not in EXors support to the current picture in which FUors are more likely to represent an accretion burst in the protostellar phase (Class I), while EXors are smaller accretion events in the protoplanetary (Class II) phase.

description: We have conducted a comprehensive survey of emission-line galaxies at $z\lesssim1.6$ based on narrowband (NB) imaging data taken with Hyper Suprime-Cam (HSC) on the Subaru telescope. In this paper, we update the catalogs of H$α$, [OIII], and [OII] emission-line galaxies using the data from the second Public Data Release (PDR2) of Subaru Strategic Program (SSP) of HSC and Cosmic HydrOgen Reionization Unveiled with Subaru (CHORUS) survey along with the spectroscopic redshifts for 2,019 emission-line galaxies selected with the PDR1 data. The wider effective coverage of NB816 and NB921, 16.3 deg$^2$ and 16.9 deg$^2$ respectively, are available in the Deep and UltraDeep layers of HSC-SSP from the PDR2. The CHORUS survey provides us with data with additional three NBs (NB527, NB718, and NB973) in the COSMOS field in the UltraDeep layer (1.37 deg$^2$). The five NB datasets allow us to investigate the star-forming galaxies presenting emission-lines at 14 specific redshifts ranging from $z\sim1.6$ down to $z\sim0.05$. We revisit the distribution of large-scale structures and luminosity functions (LFs) for the emission-line galaxies with the large samples of 75,377 emission-line galaxies selected. The redshift revolution of LFs shows that the star formation rate densities (SFRDs) decreases monotonically from $z\sim1.6$, which is consistent with the cosmic SFRD ever known. Our samples of emission-line galaxies covering a sufficiently large survey volume are useful to investigate the evolution of star-forming galaxies since the cosmic noon in a wide range of environments including galaxy clusters, filaments, and voids.

description: Fourier transforms project functions and signals onto a space of orthogonal trigonometric functions. The transform preserves all the information contained in a function and gives insight into the spectral components, or different frequency components, that make up the function. As a result, Fourier trans- forms have been useful in many fields of engineering, mathematics, statistics and finance. This paper will discuss some potential new uses of Fourier transforms in financial time series analysis. First, we show that traditional autoregressive models omit information that is captured by a Fourier transform. We then apply spectral decomposition to obtain better parameter estimates for an autoregressive process with a new estimation technique. For a certain set of parameters, the spectral decomposition estimator is more accurate and more precise than a traditional maximum likelihood estimator. We conclude with a discussion on extending this method to covariance estimation.
Markov chain Monte Carlo algorithm comparisons
Creators: name: Wen, Sijin
Publisher: name: University of British Columbia
Year: 2009

description: Various Markov chain Monte Carlo algorithms are available for sampling from a posterior distribution. The random walk Metropolis algorithm is a simple scheme which is frequently used in Bayesian statistical problem. The guided walk algorithm attempts to suppress the random walk behavior in the random walk Metropolis algorithm. Other algorithms, such as the Langevin algorithm and the hybrid algorithm use more information about the posterior distribution than the random walk Metropolis algorithm and the guided walk algorithm. In this thesis, The performance of each of those four algorithms has been examined, based on simulation studies using multivariate normal target distributions. Then we compare the algorithms in terms of efficiency and convergence time. Moreover, these four algorithms are compared using a posterior distribution for parameters given observed data in an application.
Amplifying the Voices of Historically Underrepresented Australian Women through Podcasting

Publisher: name: Swinburne
Year: 2024

description: This practice-led project examines the podcast’s capacity to amplify the voices of historically underrepresented Australian women. It comprises a podcast artefact called 'Maiden Australia' and the accompanying exegesis. The podcast, Maiden Australia, is a three-part anthology series that captures the stories of women who have been hidden in Australia's mainstream history, as detailed through the perspectives of various women interviewees. The exegesis examines each stage of the process of creating this podcast, illustrating how feminist methodological frameworks in conjunction with the practice of podcasting allowed for an innovative recalibration of historical narratives that raises multiple and varied women’s voices.

description: We present deep 3.6 - 8 micron imaging of the Hubble Deep Field South with IRAC on the Spitzer Space Telescope. We study Distant Red Galaxies (DRGs) at z>2 selected by Js - Ks > 2.3 and compare them to a sample of Lyman Break Galaxies (LBGs) at z=2-3. The observed UV-to-8 micron spectral energy distributions are fit with stellar population models to constrain star formation histories and derive stellar masses. We find that 70% of the DRGs are best described by dust-reddened star forming models and 30% are very well fit with old and ``dead'' models. Using only the I - Ks and Ks - 4.5 micron colors we can effectively separate the two groups. The dead systems are among the most massive at z~2.5 (mean stellar mass = 0.8 x 10^11 Msun) and likely formed most of their stellar mass at z>5. To a limit of 0.5 x 10^11 Msun their number density is ~10 x lower than that of local early-type galaxies. Furthermore, we use the IRAC photometry to derive rest-frame near-infrared J, H, and K fluxes. The DRGs and LBGs together show a large variation (a factor of 6) in the rest-frame K-band mass-to-light ratios (M/L_K), implying that even a Spitzer 8 micron-selected sample would be very different from a mass-selected sample. The average M/L_K of the DRGs is about three times higher than that of the LBGs, and DRGs dominate the high-mass end. The M/L_K ratios and ages of the two samples appear to correlate with derived stellar mass, with the most massive galaxies being the oldest and having the highest mass-to-light ratios, similar as found in the low-redshift universe.

Scaling of Energy Dissipation in Nonequilibrium Reaction Networks

description: The energy dissipation rate in a nonequilibirum reaction system can be determined by the reaction rates in the underlying reaction network. By developing a coarse-graining process in state space and a corresponding renormalization procedure for reaction rates, we find that energy dissipation rate has an inverse power-law dependence on the number of microscopic states in a coarse-grained state. The dissipation scaling law requires self-similarity of the underlying network, and the scaling exponent depends on the network structure and the flux correlation. Implications of this inverse dissipation scaling law for active flow systems such as microtubule-kinesin mixture are discussed.
