description: Oscillatory reconnection is a time-dependent magnetic reconnection mechanism that naturally produces periodic outputs from aperiodic drivers. This paper aims to quantify and measure the periodic nature of oscillatory reconnection for the first time. We solve the compressible, resistive, nonlinear MHD equations using 2.5D numerical simulations. We identify two distinct periodic regimes: the impulsive and stationary phases. In the impulsive phase, we find the greater the amplitude of the initial velocity driver, the longer the resultant current sheet and the earlier its formation. In the stationary phase, we find that the oscillations are exponentially decaying and for driving amplitudes 6.3 - 126.2 km/s, we measure stationary-phase periods in the range 56.3 - 78.9 s, i.e. these are high frequency (0.01 - 0.02 Hz) oscillations. In both phases, we find that the greater the amplitude of the initial velocity driver, the shorter the resultant period, but note that different physical processes and periods are associated with both phases. We conclude that the oscillatory reconnection mechanism behaves akin to a damped harmonic oscillator.

description: We present a new technique for the determination of the low-mass slope ($α_1$; $M_* < 0.5 M_{\odot}$) of the present day stellar mass function (PDMF) using the pixel space fitting of integrated light spectra. It can be used to constrain the initial mass function (IMF) of stellar systems with relaxation timescales exceeding the Hubble time and testing the IMF universality hypothesis. We provide two versions of the technique: (1) a fully unconstrained determination of the age, metallicity, and $α_1$ and (2) a constrained fitting by imposing the externally determined mass-to-light ratio of the stellar population. We have tested our approach by Monte-Carlo simulations using mock spectra and conclude that: (a) age, metallicity and $α_1$ can be precisely determined by applying the unconstrained version of the code to high signal-to-noise datasets (S/N=100, R=7000 yield $Δα_1 \approx 0.1$); (b) the $M/L$ constraint significantly improves the precision and reduces the degeneracies, however its systematic errors will cause biased $α_1$ estimates; (c) standard Lick indices cannot constrain the PDMF because they miss most of the mass function sensitive spectral features; (d) the $α_1$ determination remains unaffected by the high-mass IMF shape ($α_3$; $M_* \ge 1 M_{\odot}$) variation for stellar systems older than 8 Gyr, while the intermediate-mass IMF slope ($α_2$; $0.5 \le M_* < 1 M_{\odot}$) may introduce biases into the best-fitting $α_1$ values if it is different from the canonical value $α_2 = 2.3$. We analysed observed intermediate resolution spectra of ultracompact dwarf galaxies with our technique and demonstrated its applicability to real data.

title: Effects of Control Device and Task Complexity on Performance and Task Shedding During a Robotic Arm Task
Creators: name: Long, Shelby K.
Publisher: name: Old Dominion University Libraries

description: The use of robotic arms across domains is increasing, but the relationship between control features and performance is not fully understood. The goal of this research was to investigate the difference in task performance when using two different control devices at high and low task complexities when participants can shed tasks to automation. In this experiment, 40 undergraduates (24 females) used two control devices, a Leap Motion controller and an Xbox controller, to teleoperate a robotic arm in a high or low complexity peg placement task. Simultaneously, participants were tasked with scanning images for tanks. During the experiment, participants had the option to task shed the peg task to imperfect automation. Analyses indicated a significant main effect of control device on task completion rate and time to first grasp the peg, with completion rate higher and time lower when using the Leap. However, participants made significantly more errors with the Leap Motion controller than with the Xbox controller. Participants in both conditions task shed similarly with both control devices and task shed at similar times. The 2 x 2 mixed ANOVAs somewhat supported the proposed hypotheses. The results of this study indicate that control device impacts performance on a robotic arm task. The Leap Motion controller supports increased task completion rate and quicker peg grasps in high and low task complexity when compared with the Xbox controller. This supports the extension of Control Order Theory into three-dimensional space and suggests that the Leap Motion controller can be implemented in some domains. However, the criticality and frequency of errors should be carefully considered.

description: The average multiplicity of light nuclei and pi-mesons, emitted in HeC and CC interactions at 4.2 A GeV/c were studied as a function of number of identified protons. In both interactions, the behavior of average multiplicity of pi- mesons are in agreement with results coming from the Cascade model. The model could not describe the behavior of average multiplicity of light nuclei produced in HeC interactions. In case of CC interactions the model could describe qualitatively the behavior of the average multiplicity of light nuclei. An essential deviation was observed in some of the most central events. We believe that nuclear coalescence effect may be a reason of this deviation.

description: In cooperative games, the core is the most popular solution concept, and its properties are well known. In the classical setting of cooperative games, it is generally assumed that all coalitions can form, i.e., they are all feasible. In many situations, this assumption is too strong and one has to deal with some unfeasible coalitions. Defining a game on a subcollection of the power set of the set of players has many implications on the mathematical structure of the core, depending on the precise structure of the subcollection of feasible coalitions. Many authors have contributed to this topic, and we give a unified view of these different results.

description: Preventive care service delivery faces immense challenges when it comes to the level of coverage. Within this context, the case of child immunization is presented by applying operations management tools. This paper explores the application of integer programming techniques to support the Expanded Programme of Immunization (EPI) service in the Dera Ismail Khan District of Pakistan. The main concern here is equitable service delivery to decentralized localities based on two criteria: (1) achieving the highest possible level of vaccination among the target population; and 2) ensuring equality among geographically scattered populations, especially in rural dwellings. For this purpose two integer programming models have been applied on the basis of (1) sub-dividing health district into localities and allocating vaccinators to visit and vaccinate children within their administrative boundaries, and (2) within the localized planning system allowing vaccinators to visit and vaccinate children across the administrative boundaries subject to savings in travel time. Both models show interesting results in terms of need satisfaction and travel-time savings with a minimum level of deviation from equity. The solutions provide a trade-off between alternative organizational tactics, and the argument is made that rational planning methods applied interactively can contribute to the delivery of an immunization service that is equitable and cost effective.

The Mathematical modeling of calcium dynamics in neurons lead to the reaction diffusion equation which involves the parameters like diffusion coefficient, free calcium, bound calcium, buffers and bound buffer. Here the parameters like receptors, serca and leak are also incorporated in the model. Appropriate boundary conditions have been framed based on biophysical conditions of the problem. The finite volume method has been employed to obtain the solution. The computer program has been developed using MATLAB 7.11 for the entire problem to compute Ca2+ profiles and study the relationships among various parameters.

description: As developmental training programs grow in organization life, customized training programs including observation, collaboration with management, data gathering, research of materials to be used, and evaluation become necessary. Using these, and other methods of research, consultants are able to develop programs which focus directly on the specific needs of an independent organization and its employees; This research evaluated internal organizational communication problems "by facilitating discovery and examination of the underlying symbolic structures, constraints, and opportunities of organizational life" (Kreps, 1983; Schein, 1987; 1969). The data gathered was "generated by organizational communication research to provide insight into organizational phenomena and redirect their activities to better accomplish individual and organizational goals" (Kreps, 1989); This organizational development program was developed to improve organizational communication among employees in a local company. Information gathered from basic skills assessments in the areas of English (reading comprehension and vocabulary) and mathematics, along with the readability level of company literature, were used to enhance employee development through a customized training program.

description: The shape of materials is often subject to a number of geometric constraints that limit the size of the system or fix the structure of its boundary. In soft and biological materials, however, these constraints are not always hard, but are due to other physical mechanisms that affect the overall force balance. A capillary film spanning a flexible piece of wire or a cell anchored to a compliant substrate by mean of adhesive contacts are examples of these softly constrained systems in the macroscopic and microscopic world. In this article I review some of the important mathematical and physical developments that contributed to our understanding of shape formation in softly constrained films and their recent application to the mechanics of adherent cells.

description: The design and realization of a prototype for the Small-Size class Telescopes of the Cherenkov Telescope Array is one of the cornerstones of the ASTRI project. The prototype will adopt a focal plane camera based on Silicon Photo-Multiplier sensors that coupled with a dual mirror optics configuration represents an innovative solution for the detection of Atmospheric Cherenkov light. These detectors can be read by the Extended Analogue Silicon Photo-Multiplier Integrated Read Out Chip (EASIROC) equipped with 32-channels. In this paper, we report some preliminary results on measurements aimed to evaluate EASIROC capability of autotriggering and measurements of the trigger time walk, jitter, DAC linearity and trigger efficiency vs the injected charge. Moreover, the dynamic range of the ASIC is also reported.

Creators: name: Dunn, Malcolm R.
Publisher: name: University of Nevada, Las Vegas
Year: 1997

description: The current study investigated the extent to which challenging the informational demands of the cognitive system impact reaction time in a linear, systematic fashion. Specifically, the study examined the effects of simultaneously challenging all three stages of the information processing. A 3 (Response Selection) x 2 (Stimulus Identification) x 2 (Response Programming) ANOVA with repeated measures was used to analyze mean reaction time data. The results indicated that, to a point, information processing increases in a linear, systematic fashion. However, when the system is substantially stressed, speed of processing is negatively impacted. This results in an over-additive increase in reaction time. Movement time analysis in complex response conditions indicated a similar increase at this level of informational load. One explanation for this finding is that the cognitive system has a finite information capacity, after which efficient processing of information is hindered.

description: Graphene is a single layer of covalently bonded carbon atoms, which was discovered only 8 years ago and yet has already attracted intense research and commercial interest. Initial research focused on its remarkable electronic properties, such as the observation of massless Dirac fermions and the half-integer quantum Hall effect. Now graphene is finding application in touch-screen displays, as channels in high-frequency transistors and in graphene-based integrated circuits. The potential for using the unique properties of graphene in terahertz-frequency electronics is particularly exciting; however, initial experiments probing the terahertz-frequency response of graphene are only just emerging. Here we show that the photoconductivity of graphene at terahertz frequencies is dramatically altered by the adsorption of atmospheric gases, such as nitrogen and oxygen. Furthermore, we observe the signature of terahertz stimulated emission from gas-adsorbed graphene. Our findings highlight the importance of environmental conditions on the design and fabrication of high-speed, graphene-based devices.

description: Wireless Sensors Networks (WSNs) have a big application in heterogeneous networks. In this paper, we propose and evaluate Advanced Low-Energy Adaptive Clustering Hierarchy (Ad-LEACH) which is static clustering based heterogeneous routing protocol. The complete network field is first divided into static clusters and then in each cluster separate Ad-LEACH protocol is applied. Our proposed protocol is inherited from LEACH with a cluster head selection criteria of Distributed Energy-Efficient Clustering (DEEC). This enables Ad-LEACH to cope with the heterogeneous nature of nodes. Due to small static clusters, each node reduces its broadcast message power because it only has to cover a small area. We perform simulations in MATLAB to check the efficiency of Ad-LEACH. The Simulation results show that Ad-LEACH outperforms LEACH and DEEC in energy efficiency as well as throughput.

description: We study the single photon transfer in a hybrid system where the normal modes of two coupled resonator arrays interact with two transition arms of a ?-type atom localized in the intersectional resonator. It is found that, due to the Fano-Feshbach effect based on the dark state of the ?-type atom, the photon transfer in one array can be well controlled by the bound state of the photon in the other array. This conceptual setup could be implemented in some practical cavity QED system to realize a quantum switch for single photon.

description: This study aims to determine how the form of adolescent problems in Totoharjo Village, South Lampung, what are the causes of the problems that befell the youth of Totoharjo Village and what is the right da'wah strategy in dealing with adolescent problems in Totoharjo Village, South Lampung. The approach used in this research is a qualitative field approach and descriptive analytical method. The problems that often occur in the lives of teenagers in Totoharjo Village are leaving congregational prayers at the mosque, the unwillingness of teenagers to follow religious guidance and not appreciating morals in their daily lives. The causes of these problems include the lack of understanding of adolescent children towards religious knowledge and parental attention to changes in the child, so that children live freely and irregularly. So with this the role of da'wah is very much needed in overcoming the problems of youth by forming positive activities such as Islamic religious guidance, recitations, social services to rural communities. The results of the research; the condition of the youth of Totoharjo Village is now better than before. Da'i should always provide an understanding of the true Islam and be a role model for them.
Accurate measurement of the HI column density from HI 21cm absorption-emission spectroscopy

description: We present a detailed study of an estimator of the HI column density, based on a combination of HI 21cm absorption and HI 21cm emission spectroscopy. This "isothermal" estimate is given by $N_{\rm HI,ISO} = 1.823 \times 10^{18} \int \left[ τ_{\rm tot} \times {\rm T_B} \right] / \left[ 1 - e^{-τ_{\rm tot}} \right] {\rm dV}$, where $τ_{\rm tot}$ is the total HI 21cm optical depth along the sightline and ${\rm T_B}$ is the measured brightness temperature. We have used a Monte Carlo simulation to quantify the accuracy of the isothermal estimate by comparing the derived $N_{\rm HI,ISO}$ with the true HI column density $N_{\rm HI}$. The simulation was carried out for a wide range of sightlines, including gas in different temperature phases and random locations along the path. We find that the results are statistically insensitive to the assumed gas temperature distribution and the positions of different phases along the line of sight. The median value of the ratio of the true H{\sc i} column density to the isothermal estimate, $N_{\rm HI}/{N_{\rm HI, ISO}}$, is within a factor of 2 of unity while the 68.2% confidence intervals are within a factor of $\approx 3$ of unity, out to high HI column densities, $\le 5 \times 10^{23}$\,cm$^{-2}$ per 1 km s$^{-1}$ channel, and high total optical depths, $\le 1000$. The isothermal estimator thus provides a significantly better measure of the HI column density than other methods, within a factor of a few of the true value even at the highest columns, and should allow us to directly probe the existence of high HI column density gas in the Milky Way.

title: The effectiveness of court appointed special advocates (Casas) to assist in permanency planning
Creators: name: Calkins, Cynthia Ann
Publisher: name: University of Nevada, Las Vegas
Year: 1997

description: The effectiveness of permanency planning, which refers to efforts to move children through the court system in a timely and efficient manner, was analyzed by comparing outcome and process measures among a group of children having a court appointed special advocate (CASA) ordered and assigned to their case, a group of children who had CASA services ordered, but never assigned to their case (CONA), and a group of children who never had a CASA ordered nor assigned to their case (NO CASA). It was found that those cases having CASA involvement had significantly fewer placements, tended to be more likely to achieve permanency, and tended to spend less overall time under wardship of the court. However the more activities a CASA did, in terms of the process measures, related to a longer time under wardship of the court, a greater number of placements, and less likelihood of achieving permanency.

description: The ideas of digital simulation of quantum systems using a quantum computer parallel the original ideas of numerical simulation using a classical computer. In order for quantum computational simulations to advance to a competitive point, many techniques from classical simulations must be imported into the quantum domain. In this article, we consider the applications of symmetry in the context of quantum simulation. Building upon well established machinery, we propose a form of first quantized simulation that only requires the spatial part of the wave function, thereby allowing spin-free quantum computational simulations. We go further and discuss the preparation of N-body states with specified symmetries based on projection techniques. We consider two simple examples, molecular hydrogen and cyclopropenyl cation, to illustrate the ideas. While the methods here represent adaptations of known quantum algorithms, they are the first to explicitly deal with preparing N-body symmetry-adapted states.

We also briefly review the conversion of wormholes into time-machines, explore several of the time travel paradoxes and possible remedies to these intriguing side-effects in wormhole physics.

description: Microlensing experiments are returning increasingly detailed information about the planetary and binary systems that are being detected, far beyond what was originally expected. In several cases the lens mass and distance are measured, and a few very special cases have yielded complete 8-parameter Kepler solutions, i.e., the masses of both components, five Kepler invariants and the phase. We identify one such case that is suitable for a precision test that could be carried out by comparing Doppler (RV) measurements with the predictions from the microlensing solution. The lens primary is reasonably bright (I=16.3, V=18.0) and is expected to have a relatively large RV semi-amplitude K ~ 6.35 km/s).

description: Why and how may some active regions (ARs) frequently produce coronal mass ejections (CMEs)? It is one of the key questions to deepen our understanding of the mechanisms and processes of energy accumulation and sudden release in ARs and to improve our capability of space weather prediction. Although some case studies have been made, the question is still far from fully answered. This issue is now being tried to address statistically through an investigation of waiting times of quasi-homologous CMEs from super ARs in solar cycle 23. It is found that the waiting times of quasi-homologous CMEs have a two-component distribution with a separation at about 18 hours. The first component is a Gaussian-like distribution with a peak at about 7 hours, which indicates a tight physical connection between these quasi-homologous CMEs. The likelihood of occurrences of two or more CMEs faster than 1200 km s-1 from the same AR within 18 hours is about 20%. Furthermore, the correlation analysis among CME waiting times, CME speeds and CME occurrence rates reveals that these quantities are independent to each other, suggesting that the perturbation by preceding CMEs rather than free energy input be the direct cause of quasi-homologous CMEs. The peak waiting time of 7 hours probably characterize the time scale of the growth of instabilities triggered by preceding CMEs. This study uncovers more clues from a statistical perspective for us to understand quasi-homologous CMEs as well as CME-rich ARs.

description: An experiment replicated and extended recent findings on psychologically realistic ways of modeling propagation of uncertainty in rule based reasoning. Within a single production rule, the antecedent evidence can be summarized by taking the maximum of disjunctively connected antecedents and the minimum of conjunctively connected antecedents. The maximum certainty factor attached to each of the rule's conclusions can be sealed down by multiplication with this summarized antecedent certainty. Heckerman's modified certainty factor technique can be used to combine certainties for common conclusions across production rules.

title: Yield management and its practical application in hotels
Creators: name: Caneen, Jeffrey M.

description: Yield management is an approach to pricing that is often used by industries in which the marginal production cost is relatively high, while the marginal sales cost is relatively low. The hotel industry meets this criterion. Industry publications demonstrate a keen interest in the revenue enhancing potential of yield management, but there has been little research on the extent to which this pricing technique is actually utilized by hotel general managers; This research tests the proposition that there are eight basic elements of yield management in hotels. The degree to which yield management is practiced is indicated by the extent that these eight elements are in place. It was found that there is a positive relationship between a manager's perception of his or her own yield management utilization and the extent to which the 8 elements are used. It was also found, however, that while 76.9% of hotels claim to be utilizing yield management techniques extensively, very few are using all of the basic elements in their efforts to maximize revenue.

description: Here I am proposing a discussion of some parts of the De Generatione Sonorum, one of the short treatises written by Robert Grosseteste. The main subject of this treatise is the phonetics. However, sound and oscillations are shortly described. Since Grosseteste discussed a phonetics based on the analogy with motions and their combinations, we can find in this text some hints on how a medieval scholar approached the description of motions.

title: Defying the odds: The Christian Coalition in the life cycle of the Religious Right
Creators: name: Espin, Kathleen S
Publisher: name: University of Nevada, Las Vegas
Year: 1997

description: According to the established theories on the life cycle of social movements, the Maintenance Stage of a movement is a critical time that marks a crossroads. One path leads to victory and the other to oblivion. The odds are strongly against victory for any social movement because the bureaucratic necessities for long-term maintenance of a movement siphon off spontaneity, excitement, and "esprit de corps." Few social movements are totally successful and many are absorbed or cooped by established institutions. This study examines how the Religious Right, under the leadership of the Christian Coalition, has defied the odds and has become more powerful while transforming itself into a mainstream political organization. A carefully planned shift in rhetorical strategy has helped the Christian Coalition coopt an established institution, the Republican Party, rather than being cooped by it.

description: Underwater Wireless Sensor Networks are significantly different from terrestrial sensor networks due to peculiar characteristics of low bandwidth, high latency, limited energy, node float mobility and high error probability. These features bring many challenges to the network protocol design of UWSNs. Several routing protocols have been developed in recent years for these networks. One of the major difficulties in comparison and validation of the performance of these proposals is the lack of a common standard to model the acoustic propagation in the harsh underwater environment. In this paper we analyze the evolution of certain underwater routing protocols like VBF, DBR, H2-DAB, QELAR etc. in terms of their localization techniques, energy minimization characteristics and holding time calculations. The design of each protocol follows certain goals i.e. reduction of energy consumption, improvement of communication latency, achievement of robustness and scalability etc. This paper examines the main approaches and challenges in the design and implementation of underwater sensor networks. The detailed descriptions of the selected protocols contribute in understanding the direction of the current research on routing layer in UWSN.
title: The relationship between plasma potassium and the ventilatory drift during continuous steady state exercise

description: Recently, potassium has been investigated as a possible metabolite involved in the control exercise ventilation. Graded and incremental cycle tests using healthy subjects show a strong correlation between plasma potassium (K{dollar}\sp+{dollar}) and ventilation (V{dollar}\sb{\rm E}).{dollar} However, the role of potassium has not been investigated during steady state exercise. During steady state exercise researchers have observed a ventilatory drift that cannot be accounted for by lactate or expired carbon dioxide (VCO{dollar}\sb2).{dollar} The purpose of this study was to examine the relationship between plasma K{dollar}\sp+{dollar} levels and the ventilatory drift during steady state exercise. Participants cycled at 60% VO{dollar}\sb2{dollar} max. for 30 minutes. VO2, VCO2, V{dollar}\sb{\rm E}{dollar} plasma K{dollar}\sp+{dollar} and lactate were measured each minute. There was an 8% increase in both VO2 (p {dollar}<{dollar}.02), VE (p {dollar}<{dollar}.03) and a 16% increase in K{dollar}\sp+{dollar} (p {dollar}<{dollar}.04) between 6 and 30 minutes of exercise. VCO2 and lactate remained unchanged. There were significant correlations between V{dollar}\sb{\rm E}{dollar} vs K{dollar}\sp+{dollar} (r =.97) and VO2 vs K{dollar}\sp+{dollar} (r =.97) during steady state exercise. V{dollar}\sb{\rm E}{dollar} and lactate over the same duration were not correlated (r =.47). These results suggest a positive relationship between increases in K{dollar}\sp+{dollar} and ventilation during steady state exercise. Whether K{dollar}\sp+{dollar} is the causative agent of the ventilatory drift, however, remains to be determined.
Television crime drama program viewing and O J Simpson bias: Applying the cultivation theory

description: According to media critics, no criminal event has ever received as much publicity as the O. J. Simpson double murder case. The purpose of conducting this research was to apply the cultivation analysis theory to the O. J. Simpson case to see if heavy daily television viewers, heavy viewers of crime drama programs both realistic and fictional, and heavy newspaper and magazine readers expressed guilt against O. J. Simpson With the assistance from personnel at the Clark County Courthouse in Las Vegas, Nevada, the researcher administered 205 survey questionnaires to summoned jurors who were released from jury service. A negative correlation was found between heavy daily television viewing and belief in the likelihood that O. J. Simpson was guilty. A negative correlation was found between heavy viewing of realistic crime drama programs and belief in the likelihood that O. J. Simpson was violent with his former spouse Nicole. A positive correlation was found between heavy newspaper and magazine reading and belief in the likelihood that O. J. Simpson was guilty. The results for both television viewing variables were inconsistent with the cultivation theory since light television viewers tended to believe that O. J. Simpson was guilty. Conversely, results for the newspaper and magazine readers were consistent with the cultivation theory since heavy readers tended to believe that O. J. Simpson was guilty.

description: We present a large-scale study of the X-ray properties and near-IR-to-radio SEDs of submillimetre galaxies (SMGs) detected at 1.1mm with the AzTEC instrument across a ~1.2 square degree area of the sky. Combining deep 2-4 Ms Chandra data with Spitzer IRAC/MIPS and VLA data within the GOODS-N/S and COSMOS fields, we find evidence for AGN activity in ~14 percent of 271 AzTEC SMGs, ~28 percent considering only the two GOODS fields. Through X-ray spectral modeling and SED fitting using Monte Carlo Markov Chain techniques to Siebenmorgen et al. (2004) (AGN) and Efstathiou et al. (2000) (starburst) templates, we find that while star formation dominates the IR emission, with SFRs ~100-1000 M_sun/yr, the X-ray emission for most sources is almost exclusively from obscured AGNs, with column densities in excess of 10^23 cm^-2. Only for ~6 percent of our sources do we find an X-ray-derived SFR consistent with NIR-to-radio SED derived SFRs. Inclusion of the X-ray luminosities as a prior to the NIR-to-radio SED effectively sets the AGN luminosity and SFR, preventing significant contribution from the AGN template. Our SED modeling further shows that the AGN and starburst templates typically lack the required 1.1 mm emission necessary to match observations, arguing for an extended, cool dust component. The cross correlation function between the full samples of X-ray sources and SMGs in these fields does not indicate a strong correlation between the two populations at large scales, suggesting that SMGs and AGNs do not necessarily trace the same underlying large scale structure. Combined with the remaining X-ray-dim SMGs, this suggests that sub-mm bright sources may evolve along multiple tracks, with X-ray-detected SMGs representing transitionary objects between periods of high star formation and AGN activity while X-ray-faint SMGs represent a brief starburst phase of more normal galaxies.
