Selection of dynamical rules in spatial Prisoner's Dilemma games

We study co-evolutionary Prisoner's Dilemma games where each player can imitate both the strategy and imitation rule from a randomly chosen neighbor with a probability dependent on the payoff difference when the player's income is collected from games with the neighbors. The players, located on the sites of a two-dimensional lattice, follow unconditional cooperation or defection and use individual strategy adoption rule described by a parameter. If the system is started from a random initial state then the present co-evolutionary rule drives the system towards a state where only one evolutionary rule remains alive even in the coexistence of cooperative and defective behaviors. The final rule is related to the optimum providing the highest level of cooperation and affected by the topology of the connectivity structure.
Import demand in heterogeneous panel setting

To study the elasticities of import demand function, a heterogeneous panel is built with data of 40 countries and using panel unit root tests (Im et al., 1997) and panel cointegration tests (Pedroni, 2004). The model is tested with two previously used activity variables: GDP and GDP minus Export for a performance comparison. To estimate elasticities, use is made of two modified panel versions of FMOLS and DOLS developed by Pedroni (1996, 2000, 2001). The tests prove that GDP outperforms GDP minus Exports as an activity variable in the cointegration context. FMOLS and DOLS give close results when individual estimates are done. When between‐dimension estimators are used, conflicting results are obtained. Then, the sample is split into developed and developing countries and it is shown that income elasticity in developing countries are not different than unity on average and are higher than in developed countries contradicting previous literature results.
Running head: SCRATCHING IN POSITIVE AND NEGATIVE AROUSAL Scratching as a Behavioral Indicator of Positive and Negative Arousal in Common Marmosets (Callithrix jacchus)

Negative emotional arousal is associated with a pattern of physiological and behavioral responses, such as increases in heart rate, blood pressure, and locomotion. In captive Old World monkeys and apes, self-directed scratching is a well-known behavioral indicator of negative arousal, with increased rates of scratching occurring in conjunction with simulated predation threats, social competition, cognitive challenge, and interactions with dominant conspecifics. Additionally, scratching in the context of negative arousal has also been found to be lateralized (i.e., scratching is directed to one side of the body or the other). For example, chimpanzees tend to prefer to use the right hand to scratch the left side of the body during anxiety-provoking circumstances. I tested the prediction that scratching in response to negative arousal generalizes to a sample of naturally-housed New World primates (common marmosets; Callithrix jacchus). The second aim of my thesis was to determine if contexts of positive arousal (play, food anticipation, and foraging) are also associated with increased rates of scratching, a question that has not yet been addressed in the literature. Finally, I predicted that subjects would scratch more with the left hand than the right during negative arousal, and examined with which hand subjects would scratch more during positive arousal. Contrary to the first prediction, and contrary to the widely accepted assumption that there is a positive relationship between anxiety and scratching in primates, my results showed that scratching significantly decreased in response to all three negative arousal contexts. Contexts within positive arousal showed varying patterns of scratching between baseline, manipulation, and post-manipulation periods. There were no differences between the frequency of left and right limb scratches during negative arousal manipulations. There was a bias for right hand scratching in the positive arousal conditions, but the overall rates of scratching in all manipulations were too low to adequately address the prediction about 3 SCRATCHING IN POSITIVE AND NEGATIVE AROUSAL lateralized scratching. Overall, data from this study point to the conclusion that the anxietyscratching relationship may be more complex than is generally accepted in the literature.
Pezaros, D., Sifalakis, M. and Mathy, L. (2007) Fractal analysis of intraflow unidirectional delay over W-LAN and W-WAN environments. In: The 5th International Symposium on Modelling and Optimisation in Mobile, Ad Hoc, and Wireless Networks

we have analysed unidirectional delay traces of a diverse set of IPv6 microflows routed over W-LAN and W-WAN environments. Using a number of time-domain and frequencydomain estimators we have examined the existence and intensity of long-range dependence in packet delay when viewed as time-series data. The correlation structures of packet delay on bulk TCP data path and UDP flows follow asymptotic decay while Hurst exponent estimates suggest from moderate to strong intensity ( 1) H → .
Guided Sequence-to-Sequence Learning with External Rule Memory

External memory has been proven to be essential for the success of neural network-based systems on many tasks, including Question-Answering, classification, machine translation and reasoning. In all those models the memory is used to store instance representations of multiple levels, analogous to “data” in the Von Neumann architecture of a computer, while the “instructions” are stored in the weights. In this paper, we however propose to use the memory for storing part of the instructions, and more specifically, the transformation rules in sequence-tosequence learning tasks, in an external memory attached to a neural system. This memory can be accessed both by the neural network and by the human experts, hence serving as an interface for a novel learning paradigm where not only the instances but also the rule can be taught to the neural network. Our empirical study on a synthetic but challenging dataset verifies that our model is effective.
Quantitative Remote Sensing at Ultra-High Resolution with UAV Spectroscopy: A Review of Sensor Technology, Measurement Procedures, and Data Correction Workflows

In the last 10 years, development in robotics, computer vision, and sensor technology has provided new spectral remote sensing tools to capture unprecedented ultra-high spatial and high spectral resolution with unmanned aerial vehicles (UAVs). This development has led to a revolution in geospatial data collection in which not only few specialist data providers collect and deliver remotely sensed data, but a whole diverse community is potentially able to gather geospatial data that fit their needs. However, the diversification of sensing systems and user applications challenges the common application of good practice procedures that ensure the quality of the data. This challenge can only be met by establishing and communicating common procedures that have had demonstrated success in scientific experiments and operational demonstrations. In this review, we evaluate the state-of-the-art methods in UAV spectral remote sensing and discuss sensor technology, measurement procedures, geometric processing, and radiometric calibration based on the literature and more than a decade of experimentation. We follow the 'journey' of the reflected energy from the particle in the environment to its representation as a pixel in a 2D or 2.5D map, or 3D spectral point cloud. Additionally, we reflect on the current revolution in remote sensing, and identify trends, potential opportunities, and limitations.
Acoustic waveforms produced by a laboratory scale supersonic jet

The spatial evolution of acoustic waveforms produced by a Mach 3 jet are investigated using both 1/4 inch and 1/8 inch pressure field microphones located along rays emanating from the post potential core where the peak sound emission is found to occur. The measurements are acquired in a fully anechoic chamber where ground, or other large surface reflections are minimal. The calculation of the OASPL along an arc located at 95 jet diameters using 120 planar grid measurements are shown to collapse remarkably well when the arc array is centered on the post potential core region. Various statistical metrics, including the quadrature spectral density, number of zero crossings, the skewness of the pressure time derivative and the integral of the negative part of the quadrature spectral density, are exercised along the peak emission path. These metrics are shown to undergo rapid changes within 2 meters from the source regions of this laboratory scale jet. The sensitivity of these findings to both transducer size and humidity effects are discussed. A visual extrapolation of these nonlinear metrics toward the jet shear layer suggests that these waveforms are initially skewed at the source. An experimentally validated wave packet model is used to confirm the location where the pressure decay law transition from cylindrical to spherical. It is then used to estimate the source intensity which is required to predict the effective Gol’dberg number.
What you don't know can hurt you: Early life course racial health disparities in undiagnosed diabetes

Population estimates of health conditions come from large national surveys. However, these estimates may vary across studies for groups with differing risk for diagnosable conditions like diabetes. The purpose of the current study is to investigate differences in prevalence estimates of diabetes risk for young adults between an age-matched subsample of the NHANES and the Add Health studies. This study seeks to determine whether differences in study designs alter estimates of diabetes risk for young adults. Focal analyses explore the impact of biomarker collection nonresponse in NHANES and Add Health on diabetes risk estimates. Results indicate that African Americans are disproportionately likely to be missing biomarker data despite completing the survey portion of both studies. When diabetes status is imputed for these individuals, increased odds of nonresponse do not change predicted risk of undiagnosed diabetes. However, the multivariate models predicting undiagnosed diabetes risk yield different conclusions across studies. This suggests that the NHANES estimates for undiagnosed diabetes may be less generalizable for young adults than the estimates from the Add Health data. Further study is needed to evaluate possible race-specific nonresponse bias of biomarker data collection across the two studies.
Remote sensing methods to map and monitor the condition of coastal habitats and other surrogates for biodiversity

This report documents the adaptation and evaluation of a regional coastal water quality algorithm for the Van Diemen Gulf region with the main objective to provide an eleven year time series of key water quality parameters from daily observations of the Moderate Resolution Imaging Spectrometer (MODIS-Aqua) satellite. However, the application of this data to derive trends and to quantify change for specific regions that can be linked to other biodiversity assessments was out-of-scope of this project. - Project objectives
Biochemical Kinetics Model of DSB Repair and GammaH2AX FOCI by Non-homologous End Joining

We developed a biochemical kinetics approach to describe the repair of double strand breaks (DSB) produced by low LET radiation by modeling molecular events associated with the mechanisms of non-homologous end-joining (NHEJ). A system of coupled non-linear ordinary differential equations describes the induction of DSB and activation pathways for major NHEJ components including Ku(sub 70/80), DNA-PK(sub cs), and the Ligase IV-XRCC4 hetero-dimer. The autophosphorylation of DNA-PK(sub cs and subsequent induction of gamma-H2AX foci observed after ionizing radiation exposure were modeled. A two-step model of DNA-PK(sub cs) regulation of repair was developed with the initial step allowing access of other NHEJ components to breaks, and a second step limiting access to Ligase IV-XRCC4. Our model assumes that the transition from the first to second-step depends on DSB complexity, with a much slower-rate for complex DSB. The model faithfully reproduced several experimental data sets, including DSB rejoining as measured by pulsed-field electrophoresis (PFGE), quantification of the induction of gamma-H2AX foci, and live cell imaging of the induction of Ku(sub 70/80). Predictions are made for the behaviors of NHEJ components at low doses and dose-rates, where a steady-state is found at dose-rates of 0.1 Gy/hr or lower.
Multiparameter poly-Cauchy and poly-Bernoulli numbers and polynomials

Recently, Komastu introduced the concept of poly-Cauchy numbers and polynomials which generalize Cauchy numbers and polynomials. In this paper, we introduce new generaliza- tion of poly-Cauchy and poly-Bernoulli numbers and polynomials. Also, we introduce new generalizations of Cauchy numbers and polynomials. Moreover, we derive some identities involving the new numbers and polynomials and some types of Stirling numbers. These gives generalization of some relations poly-Cauchy and poly-Bernoulli numbers and poly- nomials. Furthermore, we obtain some relations between the multiparameter poly-Cauchy numbers and polynomials and new multiparameter poly-Bernoulli numbers and polyno- mials.
OPTIMIZATION OF REINJECTION IN GEOTHERMAL RESERVOIRS

Re-injection of produced geothermal water for pressure support is a common practice in geothermal field management. The location selection of the reinjection well and the rate of injection is a challenging subject for geothermal reservoir engineers. The goal of optimization for this type of problem is usually to find one or more combinations of geothermal re-injection well locations that will maximize the production and the pressure support at minimum cost and minimum temperature decrease. Although the number of well combinations is potentially infinite, it has been customary to prespecify a grid of potentially good well locations and then formulate the search to locate the most timeor cost-effective subset of those locations that meets production goals. To achieve this goal neural network technology is proposed. First, a knowledge base of representative solutions for a geothermal field located in Turkey was developed using a simulator. Then artificial neural networks to predict selected outcomes was trained and tested. In the next step well combinations and injection rates of these wells to predict outcomes with a given number of injection wells were generated.
The One-pass Smoke Tube Marine Boiler-Limits of Performance

This paper summarises a number of results gathered over the past few years regarding modelling and control of the one-pass smoke tube marine boiler. The purpose is to communicate our state of knowledge regarding the limits of performance in these processes. The standpoint of the paper is limits with respect to the current standard configured boiler. We present a simple second order control model for the boiler capturing also cross couplings and disturbance influence. This model is accurate over a large frequency range including the crossover frequencies. Performance limitations imposed by the actuator systems, sensor noise and neglected model dynamics are treated. Also control design guidelines are presented and suggestions for pushing the limits by new equipment presented.
STELLAR POPULATIONS AND THE STAR FORMATION HISTORIES OF LSB GALAXIES. V. WFC3 COLOR–MAGNITUDE DIAGRAMS

We present WFC3 observations of three low surface brightness (LSB) galaxies from the Schombert et al. LSB catalog that are within 11 Mpc of the Milky Way. Deep imaging at F336W, F555W, and F814W allow the construction of the V − I color–magnitude diagrams (CMD) to MI = −2. Overall 1869, 465, and 501 stellar sources are identified in the three LSB galaxies F415-3, F608-1, and F750-V1, respectively. The spatial distribution of young blue stars matches the Hα maps from ground-based imaging, indicating that star formation in LSB galaxies follows the same style as in other irregular galaxies. Several star complexes are identified, matching regions of higher surface brightness as seen from ground-based imaging. The CMD for each LSB galaxy has a similar morphology to Local Volume (LV) dwarf galaxies (i.e., a blue main sequence, blue and red He burning branches, and asymptotic giant branch (AGB) stars). The LSB CMD’s distinguish themselves from nearby dwarf CMD’s by having a higher proportion of blue main sequence stars and fewer AGB stars than expected from their mean metallicities. Current [Fe/H] values below −0.6 are deduced from the position of the red helium-burning branch (rHeB) stars in the V − I diagram. The distribution of stars on the blue helium-burning branch (bHeB) and rHeB from the U − V and V − I CMD indicate a history of constant star formation for the last 100 Myr.
Trust and justice in the formation of joint consultative committees

The paper identifies six phases in the creation of new joint staff–management consultative arrangements such as works councils or staff forums. Trust and justice theories are used to analyse the processes involved in initiating, designing, setting up and maintaining such a forum. The resulting framework considers both institutional and interpersonal aspects, and is intended to present researchers with a structure and an agenda for investigating the nature and consequences of the processes involved. The framework also provides initial guidelines to practitioners involved with establishing new consultative arrangements.
Hydraulic Properties of a Desert Soil Chronosequence in the Mojave Desert, USA

Desert pavements are prominent features in arid environments and consist of a surface layer of closely packed gravel that overlies a thin, gravel‐poor, vesicular A (Av) soil horizon. Well‐developed Av horizons form distinct and highly structured columnar peds. These structures, along with their silt‐ and clay‐rich texture, are hypothesized as controlling infiltration and hence the overall hydrologic conditions in the soil profile. The objectives of this study were to (i) evaluate how pedological development in near‐surface soil horizons in an arid alluvial fan complex affects the soil hydraulic characteristics, and (ii) to compare the use of Wooding's equation and inverse modeling for evaluating hydraulic conductivity in highly layered, near‐surface soils. These objectives were approached through field tension infiltrometer studies, soil sampling, and laboratory analyses of soil texture, water content, and soluble salt concentrations. Soils at five sites were studied at the Mojave National Preserve, California, representing a soil chronosequence (50–100000 yr) with varying degrees of desert pavement development. Results indicated 100‐fold and threefold declines, respectively, in saturated hydraulic conductivity (Ks) with both analytical methods, and αw using Wooding's method, as the soils aged. No clear trends in Ks or αw were detected in the underlying horizon, indicating that the controlling feature at these sites, in terms of water entry, was the Ks of the surface (Av) horizon. Soluble salt concentrations within the profile indicated reduced infiltration with increased pavement development. Results showed that surface age can be used as an excellent predictor of saturated hydraulic conductivity (r2 = 0.9254). Further, results suggest that Av horizon development represents a key process controlling water cycling, potentially influencing ecosystem function in arid lands.
Passive-performance, analysis, and upgrades of a 1-ton seismic attenuation system

The 10 m prototype facility at the Albert–Einstein-institute (AEI) in Hanover, Germany, employs three large seismic attenuation systems to reduce mechanical motion. The AEI seismic-attenuation-system (AEI-SAS) uses mechanical anti-springs in order to achieve resonance frequencies below 0.5 Hz. This system provides passive isolation from ground motion by a factor of about 400 in the horizontal direction at 4 Hz and in the vertical direction at 9 Hz. The presented isolation performance is measured under vacuum conditions using a combination of commercial and custom-made inertial sensors. Detailed analysis of this performance led to the design and implementation of tuned dampers to mitigate the effect of the unavoidable higher order modes of the system. These dampers reduce RMS motion substantially in the frequency range between 10 and 100 Hz in 6 degrees of freedom. The results presented here demonstrate that the AEI-SAS provides substantial passive isolation at all the fundamental mirror-suspension resonances.
PHILOSOPHY, RESEARCH, AND EDUCATION

Research always conveys a commitment to philosophical beliefs even if this is unintended and even though it remains implicit and unacknowledged. [Researchers] cannot evade the responsibility for critically examining and justifying the philosophical ideas that their enquiries incorporate. It follows that philosophical reflection and argumentation are central features of the methods and procedures of educational research. —W. Carr, 1995 (as quoted in Bridges, 1997, p. 179) Indeed . adapting from Plato on a different but not unrelated matter, one might say that there may be no good educational practice until all professional teachers become—rather than school effectiveness, action researchers or other empirical researchers—educational philosophers. —D. Carr, (2001, p. 475) The problems we face are not really technical—they are moral, they are ethical. A reliance on technical solutions leaves us still gasping, still empty. —M. Greene (as quoted in Ayers & Miller, 1998, p. 6)
