description: Recent spectroscopic observations by sensitive radio telescopes require accurate molecular spectral line frequencies to identify molecular species in a forest of lines detected. To measure rest frequencies of molecular spectral lines in the laboratory, an emission-type millimeter and submillimeter-wave spectrometer utilizing state-of-the-art radio-astronomical technologies is developed. The spectrometer is equipped with a 200 cm glass cylinder cell, a two sideband (2SB) Superconductor-Insulator-Superconductor (SIS) receiver in the 230 GHz band, and wide-band auto-correlation digital spectrometers. By using the four 2.5 GHz digital spectrometers, a total instantaneous bandwidth of the 2SB SIS receiver of 8 GHz can be covered with a frequency resolution of 88.5 kHz. Spectroscopic measurements of CH$_3$CN and HDO are carried out in the 230 GHz band so as to examine frequency accuracy, stability, sensitivity, as well as intensity calibration accuracy of our system. As for the result of CH$_3$CN, we confirm that the frequency accuracy for lines detected with sufficient signal to noise ratio is better than 1 kHz, when the high resolution spectrometer having a channel resolution of 17.7 kHz is used. In addition, we demonstrate the capability of this system by spectral scan measurement of CH$_3$OH from 216 GHz to 264 GHz. We assign 242 transitions of CH$_3$OH, 51 transitions of $^{13}$CH$_3$OH, and 21 unidentified emission lines for 295 detected lines. Consequently, our spectrometer demonstrates sufficient sensitivity, spectral resolution, and frequency accuracy for in-situ experimental-based rest frequency measurements of spectral lines on various molecular species.

description: In practical applications of graph transformation techniques to model transformations one often has the need for copying, deleting, or moving entire subgraphs that match a certain graph pattern. While this can be done using elementary node and edge operations, the transformation is rather cumbersome to write. To simplify the transformation, we have recently developed a novel approach that allows selecting subgraphs from the matched portion of the host graph, applying a filter condition to the selection, and performing a delete, move, or copy operation on the filtered result in the context of a  transformation rule. The approach has been implemented in the GReAT language and tested on examples that show the practical efficacy of the technique. The paper describes the technique in detail and illustrates its use on a real-life example.

Quality control with non-normal, censured and truncated data
Creators: name: Noghhondarian, Kazem
Publisher: name: University of British Columbia
Year: 2009

description: This research presents a new approach to the computations of control charts for non- Normal data and for those quality characteristics where the exact sampling distributions of statistics for the process mean and standard deviation are not known. We use a class of power transformations due to Box and Cox (1964), to produce data that conform best to the Normal distribution. A statistical test of significance to determine the presence of an additional between-sample variation is introduced and an appropriate control chart to control this extra variation is developed. The Likelihood Ratio (LR), statistic which has been found useful in areas such as testing of hypothesis and estimation of confidence intervals, is used to design the control charts in the original scale of measurements that are natural for the product. The major advantage of LR method is its relatively rapid convergence to its chi-square asymptote. We present a specific application in the wood industry, by constructing appropriate control charts for the final Moisture Content (MC) of kiln-dried lumber. Comparison with a previous study which used the original non-Normal MC data showed the importance of an appropriate transformation and the inclusion of the additional between-sample variation in the calculations of the control chart limits. Without these necessary steps the control chart may lose its validity and falsely signal an out of control situation. Confidence intervals and control charts for the process mean and standard deviation are developed based on the LR statistic for the Weibull and Gumbel distributions. A control chart for the percentile of strength data to maintain a rninimum strength at a desired level, is also presented. Probability plots to check the Normality assumption of the censored and truncated data are presented. Appropriate control charts for the sample estimates of mean and standard deviation for the non-Normal censored and truncated data are developed. A procedure is given to re-express the control charts for the censored and truncated data in the original scale of measurements. Complex calculations were performed without the need to program using the Mathcad™ computer analysis package. This is a highly desirable property for the non-statistically oriented user.

description: We apply a variational technique to solve the time-dependent Gross-Pitaevskii equation for Bose-Einstein condensates in which an additional dipole-dipole interaction between the atoms is present with the goal of modelling the dynamics of such condensates. We show that universal stability thresholds for the collapse of the condensates correspond to bifurcation points where always two stationary solutions of the Gross-Pitaevskii equation disappear in a tangent bifurcation, one dynamically stable and the other unstable. We point out that the thresholds also correspond to "exceptional points," i.e. branching singularities of the Hamiltonian. We analyse the dynamics of excited condensate wave functions via Poincare surfaces of section for the condensate parameters and find both regular and chaotic motion, corresponding to (quasi-) periodically oscillating and irregularly fluctuating condensates, respectively. Stable islands are found to persist up to energies well above the saddle point of the mean-field energy, alongside with collapsing modes. The results are applicable when the shape of the condensate is axisymmetric.

description: Modern models of event causality detection (ECD) are mainly based on supervised learning from small hand-labeled corpora. However, hand-labeled training data is expensive to produce, low coverage of causal expressions and limited in size, which makes supervised methods hard to detect causal relations between events. To solve this data lacking problem, we investigate a data augmentation framework for ECD, dubbed as Knowledge Enhanced Distant Data Augmentation (KnowDis). Experimental results on two benchmark datasets EventStoryLine corpus and Causal-TimeBank show that 1) KnowDis can augment available training data assisted with the lexical and causal commonsense knowledge for ECD via distant supervision, and 2) our method outperforms previous methods by a large margin assisted with automatically labeled training data.

description: In recent years, the manipulation of Fano resonances in the time domain has unlocked deep insights into a broad spectrum of systems' coherent dynamics. Here, inelastic scattering of light with coherent acoustic phonons is harnessed to achieve complex Fano resonances. The sudden change of phonon momentum during reflection leads to a transition from anti-Stokes to Stokes light scattering, producing two different resonances that interfere in the measurement process. We highlight the conditions necessary to achieve such interference, revealing an underlying symmetry between photons and phonons, and verify the theory experimentally. Then, we demonstrate the possibility to characterize energy and coherence losses at rough interfaces, thus providing a mechanism for nondestructive testing of interface quality. Our results describe numerous unexplained observations in ultrafast acoustics and can be generalized to the scattering of light with any waves.

description: Vertical excursion fixed-field alternating gradient accelerators can be designed with tunes that are invariant with respect to momentum and trajectories that are scaled images of each other displaced only in the vertical direction. This is possible using guiding fields that have a vertical exponential increase, with a skew quadrupole component in the magnet body and a solenoid component at the magnet ends. Because of the coupling this introduces, orbit and optics calculations and optimisation of parameters need to be performed numerically. In this paper, idealised magnetic fields are calculated from first principles, taking into account end fields. The parameter dependence of the optics and the dynamic aperture of the ring are calculated for the example of a ring with an approximately 25 m circumference that accelerates proton beams from 3 MeV to 12 MeV. The paper reports for the first time the design of such an accelerator lattice using tools specifically devised to analyse transverse coupled optics without the need for approximations.

description: We report on a new method for graphene synthesis and assessment of the properties of the resulting large-area graphene layers. Graphene was produced by the high pressure - high temperature growth from the natural graphitic source by utilizing the molten Fe-Ni catalysts for dissolution of carbon. The resulting large-area graphene flakes were transferred to the silicon - silicon oxide substrates for the spectroscopic micro-Raman and scanning electron microscopy inspection. The analysis of the G peak, D, T+D and 2D bands in the Raman spectra under the 488-nm laser excitation indicate that the high pressure - high temperature technique is capable of producing the high-quality large-area single-layer graphene with a low defect density. The proposed method may lead to a more reliable graphene synthesis and facilitate its purification and chemical doping.

description: High-resolution spectroscopic observations (UV HST/STIS and optical) are used to characterize the physical state and velocity structure of the multiphase interstellar medium seen towards the nearby (170 pc) star HD102065, located behind the tail of a cometary-shaped, infrared cirrus-cloud, in the area of interaction between the Sco-Cen OB association and the Local Bubble. We analyze interstellar components present along the line of sight by fitting multiple transitions from CO, CH, CH+, C I, S I, Fe I, Mg I, Mg II, Mn II, P II, Ni II, C II, N I, O I, Si III, C IV, and Si IV. The absorption spectra are complemented by H I, CO and C II emission-line spectra, H$_2$ column-densities derived from FUSE spectra, and IRAS images. Gas components of a wide range of temperatures and ionization states are detected along the line of sight. Most of the hydrogen column-density is in cold, diffuse, molecular gas at low LSR velocity. This gas is mixed with traces of warmer molecular gas traced by H2 in the J>2 levels, in which the observed CH+ must be formed. We also identify three distinct components of warm gas at negative velocities down to -20 km/s. The temperature and gas excitation are shown to increase with increasing velocity shift from the bulk of the gas. Hot gas at temperatures of several 10^5 K is detected in the most negative velocity component in the highly-ionized species. This hot gas is also detected in very strong lines of less-ionized species (Mg II, Si II* and C II*) for which the bulk of the gas is cooler. We relate the observational results to evidence for dynamical impact of the Sco-Cen stellar association on the nearby ISM. We propose a scenario where the cirrus cloud has been hit a few 10^5 yr ago by a supernova blast wave originating from the Lower Centaurus Crux group of the Sco-Cen association.

description: While the study of space charge potentials has a long history, present models are largely based on the notion of steady state equilibrium, ill-suited to describe wide bandgap semiconductors with moderate to low concentrations of defects. Here we build on color centers in diamond both to locally inject carriers into the crystal and probe their evolution as they propagate in the presence of external and internal potentials. We witness the formation of metastable charge patterns whose shape - and concomitant field - can be engineered through the timing of carrier injection and applied voltages. With the help of previously crafted charge patterns, we unveil a rich interplay between local and extended sources of space charge field, which we then exploit to show space-charge-induced carrier guiding.

We model the occurrence of claims according to a renewal process. One ruin problem considered is that of the corresponding two-dimensional risk process first leaving the positive quadrant; another is that of entering the negative quadrant. When the claims arrive according to a Poisson process, we obtain a closed form expression for the ultimate ruin probability. In the general case, we analyze the asymptotics of the ruin probability when the initial reserves of both companies tend to infinity under a Cramér light-tail assumption on the claim size distribution.

description: The paper presents a metamodel-driven model transformation approach to interchanging rules between the Semantic Web Rule Language along with the Web Ontology Language (OWL/SWRL) and Object Constraint Language (OCL) along with UML (UML/OCL). The solution is based on the REWERSE Rule Markup Language (R2ML), a MOF-defined general rule language, as a pivotal metamodel and the bidirectional transformations between OWL/SWRL and R2ML and between UML/OCL and R2ML. Besides describing mapping rules between three rule languages, the paper proposes the implementation by using ATLAS Transformation language (ATL) and describes the whole transformation process involving several MOF-based metamodels, XML schemas, EBNF grammars.

This makes Fujaba's model transformations more powerful, completely platform independent and easier to read for developers who are already familiar with OCL. By using the code generator of the Dresden Toolkit, we are able to generate executable Java code from Fujaba's model transformations including the OCL constraints.

The Flattening of Globular Clusters
Creators: name: Bergh, Sidney van den
Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: In the three nearest luminous galaxies, the Milky Way System, the Andromeda Galaxy and NGC 5128 the brightest globular clusters are rounder than the faintest ones. On the other hand (contrary to some previous results) the flattening of individual LMC clusters is found to be independent of their luminosities. This suggests the possibility that the relationship between the flattening and luminosity of clusters might depend on host galaxy luminosity. No significant differences are found between the intrinsic flattening distributions of Galactic old halo, Galactic young halo and Galactic bulge/disk clusters. Such a dependence might perhaps have been expected if tidal forces (which are largest at small Galactocentric distances) removed angular momentum from globular clusters. The preliminary conclusion by Norris that clusters with blue horizontal branches are more flattened than red HB clusters is not confirmed by the larger data base that is now available. In other words there is no evidence for the puzzling claimed correlation between the flattening and the horizontal branch morphology of Galactic globular clusters.

description: Mathematics is a compulsory subject in Nigerian secondary schools, and the subject plays an important role in the scientific and technological growth and development of the nation. A shortfall in the knowledge of the students in Mathematics means that the goal may not be realized, hence the need to improve teaching methods for solving the problem of poor performance in the subject. This study evaluated the effect of the activity-based teaching method on the students' achievement in secondary school Mathematics. The design of the study was a quasi-experimental pretest-posttest research design using intact classes. Finding revealed that there was a significant difference in the Mathematics performance between the posttest mean scores of the students who were exposed to activity-based teaching methods (experimental) and those that were taught with lecture method (control) groups after controlling for the effect of the pre-test on Mathematics scores. The paper recommends among others that secondary school Mathematics teachers should be trained and retrained to update their knowledge in the use of activity-based teaching for making the teaching and learning of Mathematics more interesting and rewarding.

description: Precise specification of meta-models is an important rerequisite for the successful application of a model-driven engineering (MDE) process. One means of precise specification are textual constraints. However, the task of constraint development is time-consuming and error-prone if done manually.
In this paper, we present both a methodology and a tool for developing constraints in a systematic way that can be integrated into a CASE tool. Thus, we provide a semi-automated means for  integrating constraints into the MDE process.

Our approach is based on an extensible library of generic constraint patterns. Constraint patterns can be combined to create complex constraints and easily parameterized in a CASE tool. Moreover, we show how these parameterized patterns are transformed into platform-independent or platform- specific  constraints by a model transformation.

Leishmania GP63 is a GPI-anchored zinc metalloproteinase that is synthesized as a preproprotein and has three potential sites for N-linked glycosylation. Recombinant GP63 was produced in Chinese hamster ovary (CHO) cells as both a GPI-anchored and secreted protein, to investigate the differences in expression levels, stability and post-translational modifications. The expression of both proteolyrically active GP63 (GP63WT) and an active site mutant of GP63 (GP63E265D) was investigated. Flow cytometry was used to follow the stability of GP63WT and GP63E265D expression on the cell surface. Expression of GP63WT was found to be unstable whether or not methotrexate (MTX) selection was maintained. In contrast expression of GP63E265D was stable under MTX selection. In the absence of selection the decline in GP63E265D expression was more gradual than the loss of GP63WT expression. Loss of GP63 expression resulted in higher growth rate nonproducer populations. Expression of recombinant GP63 on the surface of CHO cells enabled a quantitative approach to evaluate expression stability during long-term culture. Comparison of producing and nonproducing populations has given insight into the mechanisms involved in loss of recombinant protein expression. Secreted GP63 production rates were over 20 fold higher than membrane expressed protein, however the post-translational modifications of secreted and membrane expressed proteins were different. GP63 was secreted in a latent form that retained the pro-region normally processed during cell surface expression. Fast atom bombardment-mass spectrometry of the N-linked glycans isolated from both secreted and membrane expressed GP63 showed that the predominant structures were complex biantennary types, however the glycan profiles showed dramatic differences. The degree of sialylation of the membrane form was greatly reduced and the core fucosylation of biantennary structures was increased compared to the secreted form. Glycans isolated from membrane expressed protein also contained poly-N-acetyllactosamine repeats. Residence times in the secretory pathway were similar for both secreted and membrane protein. These changes in post-translational modifications represent important factors to be considered when modifying membrane expressed protein for secreted production.

description: The newest progress on the study of the strangeness in the proton and in the lowest negative parity nucleon excited state $N^*(1535)$ is reviewed. Implications on the internal quark structure of the proton, $N^*(1535)$ and other baryons are discussed. The diquark cluster picture for the 5-quark components in baryons gives a natural explanation not only to the empirical indications for a positive strangeness magnetic moment $μ_s$ and positive strangeness radius of the proton but also the longstanding mass-reverse problem of $N^*(1535)$, $N^*(1440)$ and $Λ^*(1405)$ resonances as well as the unusual decay pattern of the $N^*(1535)$ resonance. Evidence for possible existence of $N^*(1535)$'s ${1/2}^-$ SU(3) nonet partners in this picture is pointed out, and suggestion is made to search for these $1/2^-$ hyperon excited states under the well known $Σ^*(1385)$, $Λ^*(1520)$ and $Ξ^*(1530)$ peaks in various reactions.

description: We report electron tunneling spectroscopy studies on single crystalline FeSi sample performed for the case of homogeneous tunnel junction contacts and for the case of counter electrodes made from Pt-Rh alloy. Our results reveal that while the tunneling spectroscopy in the configuration with Pt-Rh tip is preferably sensitive to the d-partial density of states and to the indirect energy gap, the FeSi-FeSi type of tunnel junction yields spectroscopic information on the c-partial density of states and on the direct gap in FeSi.

description: Introduction: Immigrant and minority youth are at risk of experiencing victimization or exclusion due to their ethnic, cultural, or religious background. An increasing non-Greek population in Greek schools has led to a dramatic increase in school bullying and other forms of violence based on racial or ethnic origin.Aim: This study attempts to examine the scale and the impact of school bullying and specifically whether adolescents victimize their peers due to their ethnic background.Material-Methods: The literature was searched in the Google Scholar, Scopus and PubMed databases with the terms (ethnic victimization), (immigrant), (students) (bullying), (bullied peer), (adolescents), (ethnic minority) and (bullying cases). The search involved randomized clinical trials for a period of not more than five years and included a total of 19 studies.Results: Ethnic or cultural origin play a major role in increasing the risk of victimization of a young migrant. Regarding the forms of bullying experienced by adolescents of different ethno cultural origins, it is found that the dominant form is verbal, followed by physical, relational and other indirect forms. At the same time, it was observed that low levels of positive attitude towards migrants are the basis for further incidents of ethnic-based intimidation. Finally, the type of involvement of the teenager in bullying incidents is not significantly influenced by the ethnocultural origin of the adolescent.Conclusions: Ethnic minority adolescents were considerably more at risk of becoming racially victimized in comparison with their peers.

description: We give some semantic results for an epistemic logic incorporating dynamic operators to describe information changing events. Such events include epistemic changes, where agents become more informed about the non-changing state of the world, and ontic changes, wherein the world changes. The events are executed in information states that are modeled as pointed Kripke models. Our contribution consists of three semantic results. (i) Given two information states, there is an event transforming one into the other. The linguistic correspondent to this is that every consistent formula can be made true in every information state by the execution of an event. (ii) A more technical result is that: every event corresponds to an event in which the postconditions formalizing ontic change are assignments to `true' and `false' only (instead of assignments to arbitrary formulas in the logical language). `Corresponds' means that execution of either event in a given information state results in bisimilar information states. (iii) The third, also technical, result is that every event corresponds to a sequence of events wherein all postconditions are assignments of a single atom only (instead of simultaneous assignments of more than one atom).

description: Low-lying excited states in the $N=32$ isotope $^{50}$Ar were investigated by in-beam $γ$-ray spectroscopy following proton- and neutron-knockout, multi-nucleon removal, and proton inelastic scattering at the RIKEN Radioactive Isotope Beam Factory. The energies of the two previously reported transitions have been confirmed, and five additional states are presented for the first time, including a candidate for a 3$^-$ state. The level scheme built using $γγ$ coincidences was compared to shell-model calculations in the $sd-pf$ model space, and to ab initio predictions based on chiral two- and three-nucleon interactions. Theoretical proton- and neutron-knockout cross sections suggest that two of the new transitions correspond to $2^+$ states, while the previously proposed $4^+$ state could also correspond to a $2^+$ state.

description: Among inflammatory nonspecific diseases of the genitourinary tract in men, a special place is occupied by chronic bacterial prostatitis, which is a fairly common pathology. Despite the progress achieved in their study and modern approaches to treatment, this problem is becoming increasingly relevant. According to statistics, 40-56% of men of working age are diagnosed with an inflammatory process in the prostate gland, the etiological agents of which are opportunistic microorganisms [43,48, 98].

description: We study the superconducting correlations induced in graphene when it is placed between two superconductors, focusing in particular on the supercurrents supported by the 2D system. For this purpose we make use of a formalism placing the emphasis on the many-body aspects of the problem, with the aim of investigating the dependence of the critical currents on relevant variables like the distance L between the superconducting contacts, the temperature, and the doping level. Thus we show that, despite the vanishing density of states at the Fermi level in undoped graphene, supercurrents may exist at zero temperature with a natural 1/L^3 dependence at large L. When temperature effects are taken into account, the supercurrents are further suppressed beyond the thermal length L_T (~ v_F / k_B T, in terms of the Fermi velocity v_F of graphene), entering a regime where the decay is given by a 1/L^5 dependence. On the other hand, the supercurrents can be enhanced upon doping, as the Fermi level is shifted by a chemical potential μfrom the charge neutrality point. This introduces a new crossover length L* ~ v_F / μ, at which the effects of the finite charge density start being felt, marking the transition from the short-distance 1/L^3 behavior to a softer 1/L^2 decay of the supercurrents at large L. It turns out that the decay of the critical currents is given in general by a power-law behavior, which can be seen as a consequence of the perfect scaling of the Dirac theory applied to the low-energy description of graphene.
