description: We study the properties of fluctuation for the free energies and internal energies of two spin glass systems that differ for having some set of interactions flipped. We show that their difference has a variance that grows like the volume of the flipped region. Using a new interpolation method, which extends to the entire circle the standard interpolation technique, we show by integration by parts that the bound imply new overlap identities for the equilibrium state. As a side result the case of the non-interacting random field is analyzed and the triviality of its overlap distribution proved.

description: Optical dipole traps and atom chips are two very powerful tools for the quantum manipulation of neutral atoms. We demonstrate that both methods can be combined by creating an optical lattice potential on an atom chip. A red-detuned laser beam is retro-reflected using the atom chip surface as a high-quality mirror, generating a vertical array of purely optical oblate traps. We load thermal atoms from the chip into the lattice and observe cooling into the two-dimensional regime where the thermal energy is smaller than a quantum of transverse excitation. Using a chip-generated Bose-Einstein condensate, we demonstrate coherent Bloch oscillations in the lattice.

description: A common feature in Answer Set Programming is the use of a second negation, stronger than default negation and sometimes called explicit, strong or classical negation. This explicit negation is normally used in front of atoms, rather than allowing its use as a regular operator. In this paper we consider the arbitrary combination of explicit negation with nested expressions, as those defined by Lifschitz, Tang and Turner. We extend the concept of reduct for this new syntax and then prove that it can be captured by an extension of Equilibrium Logic with this second negation. We study some properties of this variant and compare to the already known combination of Equilibrium Logic with Nelson's strong negation.

description: The explosive growth of spatial data and extensive utilization of spatial databases emphasize the necessity for the automated discovery of spatial knowledge. In modern times, spatial data mining has emerged as an area of voluminous research. Forest fires are a chief environmental concern, causing economical and ecological damage while endangering human lives across the world. The fast or early detection of forest fires is a vital element for controlling such phenomenon. The application of remote sensing is at present a significant method for forest fires monitoring, particularly in vast and remote areas. Different methods have been presented by researchers for forest fire detection. The motivation behind this research is to obtain beneficial information from images in the forest spatial data and use the same in the determination of regions at the risk of fires by utilizing Image Processing and Artificial Intelligence techniques. This paper presents an intelligent system to detect the presence of forest fires in the forest spatial data using Artificial Neural Networks. The digital images in the forest spatial data are converted from RGB to XYZ color space and then segmented by employing anisotropic diffusion to identify the fire regions. Subsequently, Radial Basis Function Neural Network is employed in the design of the intelligent system, which is trained with the color space values of the segmented fire regions. Extensive experimental assessments on publicly available spatial data illustrated the efficiency of the proposed system in effectively detecting forest fires.

description: Oligodepsipeptides (ODPs) with alternating amide and ester bonds prepared by ring-opening polymerization of morpholine-2,5-dione derivatives are promising matrices for drug delivery systems and building blocks for multifunctional biomaterials. Here, we elucidate the behavior of three telechelic ODPs and one multiblock copolymer containing ODP blocks at the air-water interface. Surprisingly, whereas the oligomers and multiblock copolymers crystallize in bulk, no crystallization is observed at the air-water interface. Furthermore, polarization modulation infrared reflection absorption spectroscopy is used to elucidate hydrogen bonding and secondary structures in ODP monolayers. The results will direct the development of the next ODP-based biomaterial generation with tailored properties for highly sophisticated applications.

description: In this work, we present a mechanical example of an experimental realization of a stability reversal between on-site and inter-site centered localized modes. A corresponding realization of a vanishing of the Peierls-Nabarro barrier allows for an experimentally observed enhanced mobility of the localized modes near the reversal point. These features are supported by detailed numerical computations of the stability and mobility of the discrete breathers in this system of forced and damped coupled pendula. Furthermore, additional exotic features of the relevant model, such as dark breathers are briefly discussed.

Electronic defects as reaction intermediates in sodium chloride films
Creators: name: Adams, Richard James
Publisher: name: University of British Columbia
Year: 2011

description: Evaporated films of radioactive sodium chloride have been prepared by direct sublimation onto a water cooled quartz substrate at 10-⁵ mm of mercury. These possess specific surfaces of from 30-100 m²/g and show remarkably high exchange reactivity to chlorine. From kinetic studies using ³⁶Cl incorporated in the solid it has been found that the extent of exchange C follows a fractional power of the time C = at[superscript n] and that the rate is independent of surface area, so that the possibility of the rate controlling step involving diffusion is ruled out. These features had been reported in an earlier study but required confirmation with a wider range of specific surface and a modified procedure to measure surface area before reaction. The major part of the work is designed to elucidate the role of electronic defects in the exchange mechanism from the pressure and temperature dependence of the exchange rate and from the effect of introducing electronic defects by X-irradiation or fluoridation. These latter processes cause the kinetics of the reaction to change completely to a second-order law, and provide strong evidence to support an earlier tentative suggestion that electronic defects are involved in the reaction, and that a process of adsorption of a chlorine molecule into a pair of defects is important. Detailed mechanisms are proposed for both the power law and the second-order reactions, largely on the basis of the pressure dependence. Both mechanisms use two species of electronic defect, corresponding to Seitz's models for V₂ and V₄ centres, and the "power law" mechanism requires a transition complex between the two defects. Measurements by X-ray diffraction on the particle size in the evaporated films has shown them to be in the range 250-500 Å, and an estimate of the strain from the same results suggests that roughly one dislocation per particle is present.

description: We report coupling between magnetic and electric orders for antiferromagnetic polycrystalline FeVO4 in which magnetism-induced polarization has been recently found in noncollinear antiferromagnetic state below the second antiferromagnetic phase transition at TN2=15.7K. In this low symmetry phase space group P-1, the magnetic field dependence of electric polarization evidences a clear magnetoelectric coupling in the noncollinear spin-configured antiferromagnetic phase. The discontinuity of magnetodielectric effect observed at the vicinity of the polar to nonpolar transition evidences competition between different magnetodielectric couplings in the two different antiferromagnetic states. The existence of thermal expansion anomaly near TN2 and magnetostriction effect support magnetoelastically mediated scenario of the observed magnetoelectric effect.

description: Several studies have investigated the effects of music on both submaximal and maximal exercise performance at a constant work-rate. However, there is a lack of research that has examined the effects of music on the pacing strategy during self-paced exercise. The aim of this study was to examine the effects of preferred music on performance and pacing during a 6 min run test (6-MSPRT) in young male adults. Twenty healthy male participants volunteered for this study. They performed two randomly assigned trials (with or without music) of a 6-MSPRT three days apart. Mean running speed, the adopted pacing strategy, total distance covered (TDC), peak and mean heart rate (HRpeak, HRmean), blood lactate (3 min after the test), and rate of perceived exertion (RPE) were measured. Listening to preferred music during the 6-MSPRT resulted in significant TDC improvement (?10%; p = 0.016; effect size (ES) = 0.80). A significantly faster mean running speed was observed when listening to music compared with no music. The improvement of TDC in the present study is explained by a significant overall increase in speed (main effect for conditions) during the music trial. Music failed to modify pacing patterns as suggested by the similar reversed “J-shaped” profile during the two conditions. Blood-lactate concentrations were significantly reduced by 9% (p = 0.006, ES = 1.09) after the 6-MSPRT with music compared to those in the control condition. No statistically significant differences were found between the test conditions for HRpeak, HRmean, and RPE. Therefore, listening to preferred music can have positive effects on exercise performance during the 6-MSPRT, such as greater TDC, faster running speeds, and reduced blood lactate levels but has no effect on the pacing strategy.

description: Given that a ferroelectric domain is generally a three dimensional entity, the determination of its area as well as its depth is mandatory for full characterization. Piezoresponse force microscopy (PFM) is known for its ability to map the lateral dimensions of ferroelectric domains with high accuracy. However, no depth profile information has been readily available so far. Here, we have used ferroelectric domains of known depth profile to determine the dependence of the PFM response on the depth of the domain, and thus effectively the depth resolution of PFM detection.

description: The surface current method known in the theory of electromagnetic waves diffraction is generalized to be applied for the problems of diffraction radiation generated by a charged particle moving nearby an ideally-conducting screen in vacuum. An expression for induced surface current density leading to the exact results in the theory of transition radiation is derived, and by using this expression several exact solutions of diffraction radiation problems are found. Limits of applicability for the earlier known models based on the surface current conception are indicated. Properties of radiation from a semi-plane and from a slit in cylinder are investigated at the various distances to observer.

Asymmetric syntheses in the alkylation of substituted acetic esters
Creators: name: Rolston, John Henry
Publisher: name: University of British Columbia
Year: 2011

description: An attempt has been made to develop a model for predicting the course of an asymmetric alkylation. Thus, by considering the influence of an asymmetric center upon a reaction center located in an adjoining plane, a preferred conformation of the intermediate anion is selected. This conformation is used to predict the stereochemistry of the product. The model correctly predicts the stereochemical result of several reactions known in the literature. The (-) isobornyl and (-) menthyl esters of 2-methylbutyric acid were alkylated with 1-bromobutane in 42% yield. Both of the alkylated esters were reduced with lithium aluminium hydride and the 2-methyl-2-ethylhexan-1-ol isolated by gas-liquid chromatography was shown to be optically inactive. The lack of an observable rotation does not permit a critical evaluation of the proposed model in these instances. The major impurities present in the alkylation of the aforementioned esters, namely the n-butyl ether of the optically active alcohol, have been identified by independent syntheses.

description: Missing data patterns are the combinations in which the variables with missing values occur. Exploring these patterns in multivariate data can be very useful but there are few specialized tools. The current paper presents a plot that includes relevant information for visualizing these patterns. The plot is also dynamic-interactive; so, selecting elements in it permits the highlighting of those that are more relevant according to certain criteria. An example, based on college data, is used for the purposes of illustrating the capabilities of the plot.

description: Currently, criminals profile (CP) is obtained from investigators or forensic psychologists interpretation, linking crime scene characteristics and an offenders behavior to his or her characteristics and psychological profile. This paper seeks an efficient and systematic discovery of nonobvious and valuable patterns between variables from a large database of solved cases via a probabilistic network (PN) modeling approach. The PN structure can be used to extract behavioral patterns and to gain insight into what factors influence these behaviors. Thus, when a new case is being investigated and the profile variables are unknown because the offender has yet to be identified, the observed crime scene variables are used to infer the unknown variables based on their connections in the structure and the corresponding numerical (probabilistic) weights. The objective is to produce a more systematic and empirical approach to profiling, and to use the resulting PN model as a decision tool.

description: We derive a novel chiral power counting scheme for in-medium chiral perturbation theory with explicit nucleonic and pionic degrees of freedom coupled to external sources. It allows for a systematic expansion taking into account local as well as pion-mediated inter-nucleon interactions. Based on this power counting, one can identify classes of non-perturbative diagrams that require a resummation. Within this scheme, the pion self-energy in asymmetric nuclear matter is analyzed and calculated up-to-and-including next-to-leading order (NLO). It is shown that the corrections involving in-medium nucleon-nucleon interactions cancel between each other at NLO. As a result, there are no corrections up to this order to the linear density approximation for the in-medium pion self-energy.

If 20% admixtures of the $qqqq\bar{q}$ components in the proton are assumed, the theoretical value for the axial charge in our model is in good agreement with the empirical value, which can not be well reproduced in the traditional constituent quark model even though the $SU(6) \bigotimes O(3)$ symmetry breaking or relativistic effect is taken into account. We also predict an unity axial charge for $N^{*}(1440)$ with 30% $qqqq\bar{q}$ components constrained by the strong and electromagnetic decays.

description: Generalizability theory is a modern, powerful, and broad framework used to assess the reliability, or dependability, of measurements. While there exist classic works that explain the basic concepts and mathematical foundations of the method, there is currently a lack of resources addressing computational resources for those researchers wishing to apply generalizability in practice. This tutorial illustrates the efficient application of generalizability theory in the statistical software environment R, including data formatting, computing key quantities, and tabulating and visualizing results for four different study designs. The tutorial is entirely self-contained, as it includes R code to generate the example data thus allowing the reader to reproduce all computations, tables, and plots.

Publisher: name: University of Massachusetts Amherst
Year: 2016

description: A common methodological problem in the evaluation of the predictive validity of selection methods, e.g. in educational and employment selection, is that the correlation between predictor and criterion is biased. Thorndikeâ€™s (1949) formulas are commonly used to correct for this biased correlation. An alternative approach is to view the selection mechanism as a missing data mechanism. The aim of this study was to compare Thorndikeâ€™s formulas for direct and indirect range restriction scenarios with two state-of-the-art approaches for handling missing data: full information maximum likelihood (FIML) and multiple imputation by chained equations (MICE). We conducted Monte-Carlo simulations to investigate the accuracy of the population correlation estimates in dependence of the selection ratio and the true population correlation in an experimental design. For a direct range restriction scenario, the three approaches are equally accurate. For an indirect range restriction scenario, the corrections using FIML and MICE are more precise than when using Thorndikeâ€™s formula. The higher the selection ratio and the true population correlation, the higher the precision of the population correlation estimates. Our findings indicate that both missing data approaches are alternative corrections to Thorndikeâ€™s formulas, especially in the case of indirect range restriction.

Despite several decades of research, there is no licensed vaccine available to date whereas inactivated vaccines have been shown to induce severe adverse reaction in a clinical trial, with other forms of RSV vaccine also found to induce enhanced respiratory disease (ERD) in preclinical animal studies. Here, three novel facets of ERD were identified. First, RSV fusion protein (F) was fused with CD40 ligand and delivered by an adenoviral vector into BALB/c mice. In contrast to an inactivated vaccine, the vectored vaccine effectively protected animals against RSV without inducing ERD. This protection involved a robust induction of neutralizing antibodies and memory CD8 T cells, which were not observed in the ERD-inducing inactivated vaccine group. Second, the mRNA of programmed cell death-1 (PD-1) of Sigmodon hispidus or cotton rat was isolated, sequenced and the protein was characterized. Sigmodon hispidus is an excellent animal model for studying human infections of respiratory viruses including RSV. While arguably the cotton rat is the best small animal model for evaluation of RSV vaccine and antivirals, many important genes of the immune system remain to be isolated. Programmed cell death-1 (PD-1) plays an integral role in regulating many aspects of immunity by inducing suppressive signals. Using the isolated and characterized cotton rat PD-1 gene sequence, I observed decreased levels of PD-1 in cotton rats experiencing ERD induced by inactivated RSV vaccine, unraveling a new facet of vaccine-induced disease. Third, chitosan, a polysaccharide capable of augmenting immune responses with a proven safety record in animals and humans, was investigated to determine whether chitosan alone could protect animals against RSV infection and whether it could alter immune responses or immunopathology induced by inactivated RSV vaccine. Chitosan alone was found to modestly protect animals against RSV infection, while, in conjunction with inactivated RSV vaccine, it could significantly reduce RSV infection in mice. Further mechanistic investigation revealed that chitosan enhanced inactivated RSV vaccine-elicited immune responses through augmenting the induction of regulatory T cells, lung resident T cells and neutralizing antibodies while reversing Th2-skewed immune responses induced by inactivated RSV vaccine. These finding indicate ERD development has a different functional pathway from chitosan-mediated immune protection.

description: Astrometry as a technique has so far proved of limited utility when employed as either a follow-up tool or to independently search for planetary mass companions orbiting nearby stars. However, this is bound to change during the next decade. In this review, I start by summarizing past and present efforts to detect planets via milli-arcsecond astrometry. Next, I provide an overview of the variety of technical, statistical, and astrophysical challenges that must be met by future ground-based and space-borne efforts in order to achieve the required degree of astrometric measurement precision. Then, I discuss the planet-finding capabilities of future astrometric observatories aiming at micro-arcsecond precision, with a particular focus on their ability to fully describe multiple-component systems. I conclude by putting astrometry in context, illustrating its potential for important contributions to planetary science, as a complement to other indirect and direct methods for the detection and characterization of planetary systems.

title: Measurement Error and Equating Error in Power Analysis
Creators: name: Phillips, Gary W.

Publisher: name: University of Massachusetts Amherst

description: Power analysis is a fundamental prerequisite for conducting scientific research. Without power analysis the researcher has no way of knowing whether the sample size is large enough to detect the effect he or she is looking for. This paper demonstrates how psychometric factors such as measurement error and equating error affect the power of statistical tests. The overall finding is that measurement error and equating error reduce power and inflate sample size requirements. It is recommended that researchers, where appropriate, incorporate these sources of error in conducting power analysis. If either of these two sources of error are present in the data but not accounted for in the power analysis, then power will be underestimated and sample size requirements will be underestimated.

description: Research and development at the nanoscale requires a large degree of integration, from convergence of research disciplines in new fields of enquiry to new linkages between start-ups, regional actors and research facilities. Based on the analysis of two clusters in nanotechnologies (MESA+ (Twente) and other centres in The Netherlands and Minatec in Grenoble in France), the paper discusses the phenomenon of technological agglomeration: co-located scientific and technological fields associated to coordinated technology platforms to some extent actively shaped by institutional entrepreneurs. Such co-location and coordination are probably a prerequisite for the emergence of strong nanoclusters
A proof Procedure for Testing Membership in Regular Expressions

description: We propose an algorithm that test membership for regular expressions and show that the algorithm is correct. This algorithm is written in the style of a sequent proof system. The advantage of this algorithm over traditional ones is that the complex conversion process from regular expressions to finite automata is not needed. As a consequence, our algorithm is simple and extends easily to various extensions to regular expressions such as timed regular expressions or regular languages with the intersection.

Osmotic compression of droplets of hard rods: A computer simulation study

description: By means of computer simulations we study how droplets of hard, rod-like particles optimize their shape and internal structure under the influence of the osmotic compression caused by the presence of spherical particles that act as depletion agents. At sufficiently high osmotic pressures the rods that make up the drops spontaneously align to turn them into uniaxial nematic liquid crystalline droplets. The nematic droplets or "tactoids" that are formed this way are not spherical but elongated, resulting from the competition between the anisotropic surface tension and the elastic deformation of the director field. In agreement with recent theoretical predictions we find that sufficiently small tactoids have a uniform director field, whilst large ones are characterized by a bipolar director field. From the shape and director-field transformation of the droplets we are able to estimate the surface anchoring strength and an average of the elastic constants of the hard-rod nematic.
Double charge transfer absorption in solution.

Publisher: name: University of British Columbia

description: The theory of charge-transfer spectra has been described briefly with respect to the energy, symmetry and intensity of charge-transfer transitions. The concepts derived were then applied to the special case of double charge-transfer absorption in donor/acceptor complexes between substituted benzenes and tetracyanoethylene. A first-order perturbation method treating specifically the perturbation of the substituted donor cation was discussed in detail since it is of particular importance to the interpretation of multiple charge-transfer spectra as investigated here. A detailed experimental study of the various aspects of double charge-transfer absorption has been presented in the second chapter. The equilibrium constants and extinction coefficients for both charge-transfer transitions of a number of increasingly methoxy-substituted benzene/TCNE complexes have been reported. TCNE was found to form stable complexes with these donors. For some complexes the variation of the relative molar extinction coefficients with temperature of the two c.-t. transitions of a complex was measured. A small but definite difference in heat of formation was obtained for transitions I and II. This was taken as evidence for the existence of two configurational isomers in the complexes measured. Extensive data on the effect of polar and nonpolar solvents on the positions, relative intensities, band widths and band separations of the two transitions, respectively, for the p-dimethoxy/TCNE and o-dimethoxy/TCNE complexes were reported. In nonpolar solvents the effect of solvent on the charge-transfer energy could be described as a function of the refractive index of the solvent. In polar solvents, red as well as blue shifts of the charge-transfer bands relative to their position in cyclohexane were observed. The TCNE/ substituted benzene complexes showed high solvent specificity in many polar solvents. The data obtained are summarized in terms of potential energy curves of the complex in dependence on refractive index and polarity of solvent. Such representation could account for most of the effects observed. The dependence of charge-transfer energy on ionization potential for the TCNE/substituted benzene complexes was found to be decidedly anomalous when compared to the behavior of other π-acceptors. The problem was investigated in detail. It could be shown that the abnormal behavior of the TCNE complexes is related to the structure of the acceptor. In the last section the observed double charge-transfer spectra of substituted benzene/TCNE complexes have been compared with theory. However, the perturbation parameters as derived from experiment were found to vary, contrary to theory which defines them as constants. The discrepancy could be resolved when the coulomb interactions of the charge-transfer processes were taken into account.
title: Macro- and Micro-Validation: Beyond the ‘Five Sources’ Framework for Classifying Validation Evidence and Analysis
Creators: name: Newton, Paul E.
Publisher: name: University of Massachusetts Amherst
Year: 2016

description: This paper argues that the dominant framework for conceptualizing validation evidence and analysis â€“ the â€˜five sourcesâ€™ framework from the 1999 Standards â€“ is seriously limited. Its limitation raises a significant barrier to understanding the nature of comprehensive validation, and this presents a significant threat to effective validation practice. Motivated by a belief that â€˜validity by designâ€™ ought to be substantiated through â€˜validation of designâ€™ this paper demonstrates the importance of adopting a broader conceptual framework. It introduces a new framework, based upon the metaphor of different validation lenses through which to scrutinize assessment procedures at differing levels of detail, with micro-validation lenses at one end of a continuum and macro-validation lenses at the other. The evolution of validation theory can be seen as a very gradual, if somewhat reluctant, acknowledgement of the importance of micro-validation. This paper recommends micro-validation as the natural foundation for any comprehensive validation program. Accessed 4,156 times on https://pareonline.net from December 07, 2016 to December 31, 2019.

description: We study the M_bh - M_host relation as a function of Cosmic Time in a sample of 96 quasars from z=3 to the present epoch. In this paper we describe the sample, the data sources and the new spectroscopic observations. We then illustrate how we derive M_bh from single-epoch spectra, pointing out the uncertainties in the procedure. In a companion paper, we address the dependence of the ratio between the black hole mass and the host galaxy luminosity and mass on Cosmic Time.

title: Tutorial on Using Regression Models with Count Outcomes using R
Creators: name: Beaujean , A. Alexander

Publisher: name: University of Massachusetts Amherst
Year: 2016

description: Education researchers often study count variables, such as times a student reached a goal, discipline referrals, and absences. Most researchers that study these variables use typical regression methods (i.e., ordinary least-squares) either with or without transforming the count variables. In either case, using typical regression for count data can produce parameter estimates that are biased, thus diminishing any inferences made from such data. As count-variable regression models are seldom taught in training programs, we present a tutorial to help educational researchers use such methods in their own research. We demonstrate analyzing and interpreting count data using Poisson, negative binomial, zero-inflated Poisson, and zero-inflated negative binomial regression models. The count regression methods are introduced through an example using the number of times students skipped class. The data for this example are freely available and the R syntax used run the example analyses are included in the Appendix.
