description: Reactions of non-gem-hexanedioxytetrachlorocyclotriphosphazene (1) with monofunctional nucleophilic reagents, 2-(2-hydroxyethyl)thiophene (2), benzyl alcohol (3) and 1,1,3,3-tetramethylguanidine (4) were investigated. The reactions, using an excess of NaH, in THF solutions, under refluxing conditions and with 1:2 mole ratios allow the synthesis of the following novel cyclotriphosphazene derivatives: 2,4-dichloro-2,4-(hexane-1,6-dioxy)-6,6-[2-(2-ethoxy)hiophene]-cyclotriphosphazatriene, N3P3Cl2[O(CH2)6O-(C6H8OS)2] (5); 2,4-(hexane-1,6-dioxy)-2,4,6,6-[2-(2-ethoxy) thiophene]-cyclotriphosphazatriene, N3P3[O(CH2)6O-(C6H8OS)4] (6); 2,4-dichloro-2,4-(hexane-1,6-dioxy)-6,6-(methoxybenzene)-cyclotriphosphazatriene, N3P3Cl2[O(CH2)6O-(C6H5CH2O)2] (7); 2,4-(hexane-1,6-dioxy)-2,4,6,6-(methoxybenzene)-cyclotriphosphazatriene, N3P3[O(CH2)6O-(C6H5CH2O)4] (8); and 2,4-dichloro-2,4-(hexane-1,6-dioxy)-6,6-(1,1,3,3-tetramethyguanidine)-cyclotriphosphazatriene, N3P3Cl2[O(CH2)6O-HN-CN2(CH3)4] (9). The structures of the synthesized compounds (5–9) have been characterized by elemental analysis, TLC-MS, 1H, 13C and 31P {+1H} and {−1H} NMR spectral data.

description: Blockchains are tamper evident and tamper resistant digital ledgers implemented in a distributed fashion (i.e., without a central repository) and usually without a central authority (i.e., a bank, company, or government). At their basic level, they enable a community of users to record transactions in a shared ledger within that community, such that under normal operation of the blockchain network no transaction can be changed once published. This document provides a high-level technical overview of blockchain technology. The purpose is to help readers understand how blockchain technology works.

Toward a topological characterization of symplectic manifolds

Subjects: subject: Symplectic Geometry (math.SG)

subject: 53D

description: A topological condition is given, characterizing which closed manifolds in dimensions < 8 (and conjecturally in general) admit symplectic structures. The condition is the existence of a certain fibration-like structure called a hyperpencil. A deformation class of hyperpencils on a manifold X of any even dimension is shown to determine an isotopy class of symplectic structures on X. This provides an inverse (at least in dimensions < 8) to Donaldson's program for constructing linear systems on symplectic manifolds. It follows that (at least in dimensions < 8) the set of deformation classes of hyperpencils canonically maps onto the set of isotopy classes of rational symplectic forms up to positive scale, topologically determining a dense subset of all symplectic forms up to an equivalence relation on hyperpencils. Other applications of the main techniques are presented, including the construction of symplectic structures on domains of locally holomorphic maps, and on high-dimensional Lefschetz pencils and other linear systems.

description: We investigate spatial patterns in mobile service consumption that emerge at national scale. Our investigation focuses on a representative case study, i.e., France, where we find that: (i) the demand for popular mobile services is fairly uniform across the whole country, and only a reduced set of peculiar services (mainly operating system updates and long-lived video streaming) yields geographic diversity; (ii) even for such distinguishing services, the spatial heterogeneity of demands is limited, and a small set of consumption behaviors is sufficient to characterize most of the mobile service usage across the country; (iii) the spatial distribution of these behaviors correlates well with the urbanization level, ultimately suggesting that the adoption of geographically-diverse mobile applications is linked to a dichotomy of cities and rural areas. We derive our results through the analysis of substantial measurement data collected by a major mobile network operator, leveraging an approach rooted in information theory that can be readily applied to other scenarios.

Subjects: subject: Migration, Internal Philippines Manila

description: This thesis is an analysis of the differentials in the levels of migration and the characteristics of migrants to and from Metropolitan Manila between 1970 and 1975 using a five per cent sample of the 1975 Census as the principal source of data. Measures are presented of the levels of migration to and from Metropolitan Manila (a) from one region to another, (b) from the urban areas to the rural areas and (c) from one Metropolitan Manila city/municipality to another. Also, the age-sex education, marital status and occupational characteristics of migrants are examined. Factors that influence migration as identified in different migration models and theories are used as guides to explain variations in levels of migration and the selectivity of migrants. Regression analysis of some regional and Metropolitan Manila city/municipality variables on the volume or rate of migration is carried out to determine correlates of migration. The thesis concludes with a discussion of the implications of the findings on population redistribution and the limitations and possible further development of the study.
Professional's responses to child sexual abuse in the Australian Capital Territory

Subjects: subject: Child sexual abuse InvestigationAustralia Australian Capital Territory

description: This study investigates the relationship between workers' conceptualization of child sexual abuse and their handling of such cases, using a questionnaire to elicit usual case management, and an interview employing vignettes and controversial statements to examine the goals of, and the attitudes behind, case management strategies. The subjects of this research are 60 professionals from agencies in Canberra which deal with child sexual abuse - police, welfare, community health centres, mental health teams, schools and a group of non-government community agencies. The study focusses on intrafami1ial child sexual abuse , being the dominant type, and having quite different dynamics from sexual abuse of children by adults outside of the family unit. Child sexual abuse was originally conceptualized as a form of child maltreatment, as cases first came to notice in investigations of other forms of child maltreatment - notably physical abuse. More recently, some writers have included intrafami1ial child sexual abuse under the rubric of domestic violence, along with 'wife bashing' and marital rape - all three being seen as an attempt at perpetuation of the traditional patriarchal pattern, and as symptoms of the much described 'crisis' of the family. The effects of such disparate conceptualizations on the intervention strategies adopted by different professional groups, and by different agencies in Canberra, highlights the need for a consensus of approach, not only between different agencies, but by different professional groups working for the same agency. The result of a preliminary study of the incidence of reported child sexual abuse throughout Australia is included in this report, along with discussion of the status of national data collection, and possible reasons for the lack of progress so far. An 'Involvement Index', developed in this study, holds promise as an instrument for comparing the commitment and experience levels of professionals from different agencies, whose roles in dealing with child sexual abuse necessitate working in quite different ways. This study shows that, although child sexual abuse is acknowledged as a serious social problem by workers from all agencies sampled in Canberra, exposure of workers to these cases varies considerably amongst agencies, with doctors and community nurses seeing few cases, and police, welfare and mental health workers, and staff from non-governmental community agencies, being heavily involved. The implications of these findings are discussed, in relation to the introduction of the proposed new Child Welfare Ordinance (ACT).

description: Machine translation systems are conventionally trained on textual resources that do not model phenomena that occur in spoken language. While the evaluation of neural machine translation systems on textual inputs is actively researched in the literature , little has been discovered about the complexities of translating spoken language data with neural models. We introduce and motivate interesting problems one faces when considering the translation of automatic speech recognition (ASR) outputs on neural machine translation (NMT) systems. We test the robustness of sentence encoding approaches for NMT encoder-decoder modeling, focusing on word-based over byte-pair encoding. We compare the translation of utterances containing ASR errors in state-of-the-art NMT encoder-decoder systems against a strong phrase-based machine translation baseline in order to better understand which phenomena present in ASR outputs are better represented under the NMT framework than approaches that represent translation as a linear model.

description: We perform a series of comparisons between distance-independent photometric and spectroscopic properties used in the surface brightness fluctuations (SBF) and fundamental plane (FP) methods of early-type galaxy distance estimation. The data are taken from two recent surveys: the SBF Survey of Galaxy Distances and the Streaming Motions of Abell Clusters (SMAC) FP survey. We derive a relation between V-I colour and Mg_2 index using nearly 200 galaxies and discuss implications for Galactic extinction estimates and early-type galaxy stellar populations. We find that the reddenings from Schlegel et al (1998) for galaxies with $E(B{-}V) \gta 0.2$ mag appear to be overestimated by 5--10%, but we do not find significant evidence for large-scale dipole errors in the extinction map. In comparison to stellar population models having solar elemental abundance ratios, the galaxies in our sample are generally too blue at a given Mg_2; we ascribe this to the well-known enhancement of the $α$-elements in luminous early-type galaxies. We confirm a tight relation between stellar velocity dispersion $σ$ and the SBF `fluctuation count' parameter \Nbar, which is a luminosity-weighted measure of the total number of stars in a galaxy. The correlation between \Nbar and $σ$ is even tighter than that between Mg_2 and $σ$. Finally, we derive FP photometric parameters for 280 galaxies from the SBF survey data set. Comparisons with external sources allow us to estimate the errors on these parameters and derive the correction necessary to bring them onto the SMAC system. The data are used in a companion paper which compares the distances derived from the FP and SBF methods.

description: We investigate the orbital structure in a class of 3D models of barred galaxies. We consider different values of the pattern speed, of the strength of the bar and of the parameters of the central bulge of the galactic model. The morphology of the stable orbits in the bar region is associated with the degree of folding of the x1-characteristic. This folding is larger for lower values of the pattern speed. The elongation of rectangular-like orbits belonging to x1 and to x1-originated families depends mainly on the pattern speed. The detailed investigation of the trees of bifurcating families in the various models shows that major building blocks of 3D bars can be supplied by families initially introduced as unstable in the system, but becoming stable at another energy interval. In some models without radial and vertical 2:1 resonances we find, except for the x1 and x1-originated families, also families related to the z-axis orbits, which support the bar. Bifurcations of the x2 family can build a secondary 3D bar along the minor axis of the main bar. This is favoured in the slow rotating bar case.

description: The XA region of the Cygnus Loop is a complex zone of radiative and nonradiative shocks interacting with interstellar clouds. We combine five far ultraviolet spectral observations from the Hopkins Ultraviolet Telescope (HUT), a grid of 24 IUE spectra and a high-resolution longslit Halpha spectrum to study the spatial emission line variations across the region. These spectral data are placed in context using ground-based, optical emission line images of the region and a far-UV image obtained by the Ultraviolet Imaging Telescope (UIT). The presence of high-ionization ions (OVI, NV, CIV) indicates a shock velocity near 170 km/s while other diagnostics indicate v_shock=140 km/s. It is likely that a large range of shock velocities may exist at a spatial scale smaller than we are able to resolve. By comparing CIV 1550, CIII 977 and CIII] 1909, we explore resonance scattering across the region. We find that a significant column depth is present at all positions, including those not near bright optical/UV filaments. Analysis of the OVI doublet ratio suggests an average optical depth of about unity in that ion while flux measurements of [SiVIII] 1443 suggest a hot component in the region at just below 10^6K. Given the brightness of the OVI emission and the age of the interaction, we rule out the mixing layer interpretation of the UV emission. Furthermore, we formulate a picture of the XA region as the encounter of the blast wave with a finger of dense gas protruding inward from the pre-SN cavity.

description: The recent implementation of the Electronic Health Record (EHR) in France is part of a more general process of digitizing information flows, as the world enters the fourth industrial revolution in a phenomenon known as Industry 4.0. Behind this concept lies the concern to allow Man to remain permanently in control of his destiny, despite an increasingly interconnected world (Internet of Things, cooperative robots, augmented reality, etc.). Accordingly, the implementation of EHR must guarantee the respect for the private life of each citizen. From this perspective, healthcare professionals will therefore have to constantly ensure the protection of medical confidentiality during Electronic Data Interchange (EDI). This paper summarises the current state of the use of EHR in France. Based on a survey conducted by the European Commission to assess the deployment of digitalisation in the health sector in EU countries, this article aims to highlight the opportunities and perspectives that Industry 4.0 could bring to the health sector in France. However, this study also identifies a number of limits related to the application of such a system, the first of which is cyber threat or transhumanism. To this end, a SWOT matrix identifies the strengths and weaknesses related to the implementation of the French EHR.

description: Leishmaniasis is a tropical disease found in more than 90 countries. The drugs available to treat this disease have nonspecific action and high toxicity. In order to develop novel therapeutic alternatives to fight this ailment, pteridine reductase 1 (PTR1) and dihydrofolate reductase-thymidylate synthase (DHF-TS) have been targeted, once Leishmania is auxotrophic for folates. Although PTR1 and DHFR-TS from other protozoan parasites have been studied, their homologs in Leishmania chagasi have been poorly characterized. Hence, this work describes the optimal conditions to express the recombinant LcPTR1 and LcDHFR-TS enzymes, as well as balanced assay conditions for screening. Last but not the least, we show that 2,4 diaminopyrimidine derivatives are low-micromolar competitive inhibitors of both enzymes (LcPTR1 Ki = 1.50–2.30 µM and LcDHFR Ki = 0.28–3.00 µM) with poor selectivity index. On the other hand, compound 5 (2,4-diaminoquinazoline derivative) is a selective LcPTR1 inhibitor (Ki = 0.47 µM, selectivity index = 20).

description: We study the solution of block-structured linear algebra systems arising in optimization by using iterative solution techniques. These systems are the core computational bottleneck of many problems of interest such as parameter estimation, optimal control, network optimization, and stochastic programming. Our approach uses a Krylov solver (GMRES) that is preconditioned with an alternating method of multipliers (ADMM). We show that this ADMM-GMRES approach overcomes well-known scalability issues of Schur complement decomposition in problems that exhibit a high degree of coupling. The effectiveness of the approach is demonstrated using linear systems that arise in stochastic optimal power flow problems and that contain up to 2 million total variables and 4,000 coupling variables. We find that ADMM-GMRES is nearly an order of magnitude faster than Schur complement decomposition. Moreover, we demonstrate that the approach is robust to the selection of the augmented Lagrangian penalty parameter, which is a key advantage over the direct use of ADMM.

description: We present observations of the Soft Gamma-ray Repeater SGR 1806-20 taken with the Chandra X-ray Observatory. We identify the X-ray counterpart of SGR 1806-20 based on detection of 7.5-s pulsations. Using three unrelated X-ray sources (and USNO stars) as position references, we are able to determine that the SGR is at alpha_{2000}=18h08m39.32s and delta_{2000}=-20o24'39.5", with rms uncertainty of 0.3" in each coordinate. We find that SGR 1806-20 is located within the 1-sigma error region determined by Interplanetary Network data and is 14+/-0.5 arcsec distant from the non-thermal core of SNR G10.0-0.3, excluding SGR 1806-20 as the origin of the core. We see evidence for a significant deviation of the spin-down of SGR 1806-20 from its long-term trend, demonstrating erratic spin-down behavior in this source similar to that seen in other SGRs. Finally, we show that there is a broad X-ray halo surrounding SGR 1806-20 out to radii ~1' due to scattering in the interstellar medium.

The political adaptation of second-generation Australians

description: The study systematically analyses the location of second-generation Australian adults (defined as those born in Australia of an immigrant father) in the economic system, it investigates their educational achievements, and examines the nature of influences on their political behaviour by specifying relations among certain variables and by comparing them to first-generation immigrants and to the native-born of a native-born father. The one per cent person's sample file of the 1981 Australian census on population and housing is used for analyses of income and education; the 1984/1985 National Social Science Survey (urban preliminary sample) is used to investigate partisanship, participation and felt efficacy. The study draws mostly on American literature for its theoretical underpinnings. The conceptual basis of this study involves a three-fold distinction: the socioeconomic system, the cultural, or 'ethnic', dimension and the political system. The socioeconomic system is explored largely in the economic domain in terms of individual income and educational achievement, the ethnic or cultural dimension in terms of the extent of economic and educational integration and in terms of influences on political behaviour. Ethnicity is defined mainly in terms of father's birthplace. The political system is examined through extent and strength of, and influences on, partisanship, through political participation and through felt political efficacy. The model which best describes the political life of second-generation Australians in the early 1980s is partial assimilation. Their pattern of political adaptation is piecemeal, complex and at times puzzling. Political adaptation appears to be a function both of location in some important sociocultural systems and of cultural differentiation. Ethnicity permeates political adaptation, although its effects vary across the major subsystems of society. In short, a dual explanation - economic and cultural - is required. Many features parallel the adaptation of the second generation in the United States half a century ago, perhaps the most general being that adaptation and ethnicity are interwoven in concept and reality. But unlike what appears to be the American experience, most second-generation Australians have been assimilated into the economic system by virtue of their success in gaining incomes which are at least the equivalent of those earned by other native-born Australians.

description: Signal sampling and reconstruction is a fundamental engineering task at the heart of signal processing. The celebrated Shannon-Nyquist theorem guarantees perfect signal reconstruction from uniform samples, obtained at a rate twice the maximum frequency present in the signal. Unfortunately a large number of signals of interest are far from being band-limited. This motivated research on reconstruction from sub-Nyquist samples, which mainly hinges on the use of random / incoherent sampling procedures. However, uniform or regular sampling is more appealing in practice and from the system design point of view, as it is far simpler to implement, and often necessary due to system constraints. In this work, we study regular sampling and reconstruction of three- or higher-dimensional signals (tensors). We show that reconstructing a tensor signal from regular samples is feasible. Under the proposed framework, the sample complexity is determined by the tensor rank---rather than the signal bandwidth. This result offers new perspectives for designing practical regular sampling patterns and systems for signals that are naturally tensors, e.g., images and video. For a concrete application, we show that functional magnetic resonance imaging (fMRI) acceleration is a tensor sampling problem, and design practical sampling schemes and an algorithmic framework to handle it. Numerical results show that our tensor sampling strategy accelerates the fMRI sampling process significantly without sacrificing reconstruction accuracy.

description: We present the first CCD mosaic of the supernova remnant G 65.3+5.7 in the optical emission lines of [O II] and [O III]. The new images reveal several diffuse and filamentary structures both inside and outside the extent of the remnant as defined by its X-ray and radio emission. The medium ionization line of [O III] 5007 provides the sharpest view to the system, while the remnant appears less filamentary in the emission line of [O II]. There are significant morphological differences between the two images strongly suggesting the presence of incomplete shock structures. Deep long-slit spectra were taken at several different positions of G 65.3+5.7. All spectra originate from shock heated gas, while the majority of them is characterized by large [O III]/Hbeta ratios. The sulfur line ratios indicate electron densities below ~200 cm^{-3}, while estimates of the shock velocities lie in the range of 90-140 km/s. Finally, the observed variations of the Halpha/Hbeta ratios may reflect the presence of intrinsic absorption affecting the optical spectra.

description: TITLE: Nonlinear Analysis to Quantify Movement Variability in Human-Humanoid Interaction ABSTRACT:
 Nonlinear analysis can be applied to investigate the dynamics of time-ordered data. Such dynamics relate to sensorimotor variability in the context of human-humanoid interaction. Hence, this dissertation not only explores questions such as how to quantify movement variability or which methods of nonlinear analysis are appropriate to quantify movement variability but also how methods of nonlinear analysis are affected by real-world time series data (e.g. non-stationary, data length size, sensor sources or noise). Methods are explored to determine embedding parameters, reconstructed state spaces, recurrence plots and recurrence quantification analysis. Additionally, this thesis presents three dimensional surface plots of recurrence quantification analysis with which to consider the variation of embedded parameters and recurrence thresholds. These show that three dimensional surface plots of Shannon entropy might be a suitable approach to understand the dynamics of real-world time series data. This thesis opens new avenues of applications in human-humanoid interaction where humanoid robots can be pre-programmed with nonlinear analysis algorithms to evaluate, for instance, the improvement of movement performances, to quantify and provide feedback of skill learning or to quantify movement adaptations and pathologies.

Lensing magnification effects on the cosmic shear statistics

description: Gravitational lensing causes a correlation between a population of foreground large-scale structures and the observed number density of the background distant galaxies as a consequence of the flux magnification and the lensing area distortion. This correlation has not been taken into account in calculations of the theoretical predictions of the cosmic shear statistics but may cause a systematic error in a cosmic shear measurement. We examine its impact on the cosmic shear statistics using the semi-analytic approach. We find that the lensing magnification has no practical influence on the cosmic shear variance. Exploring possible shapes of redshift distribution of source galaxies, we find that the relative amplitude of the effect on the convergence skewness is 3% at most

description: Herein, we report the effect of nine FDA approved protease inhibitor drugs against a new HIV-1 subtype C mutant protease, E35D↑G↑S. The mutant has five mutations, E35D, two insertions, position 36 (G and S), and D60E. Kinetics, inhibition constants, vitality, Gibbs free binding energies are reported. The variant showed a decreased affinity for substrate and low catalytic efficiency compared to the wild type. There was a significant decrease in the binding of seven FDA approved protease inhibitors against the mutant (p p = .0021 and .003, respectively). Nelfinavir and atazanavir were the worst inhibitors against the variant as seen from the IC50, with values of 1401 ± 3.0 and 685 ± 3.0 nM, respectively. Thermodynamics data showed less favourable Gibbs free binding energies for the protease inhibitors to the mutant.

D i s t r i b u t i o n: Greece, Western Turkey.
 R e m a r k: The female of B. rhodius from Kreta is different from specimens from other origins. It is markedly lemmon yellow, tergum VI has a large yellow spot, and body size is 12 mm. Females from eastern Greece Islands and Turkey differ in body size (9-11 mm) and in color (pale yellow, color less extended, tergum II black). With the key of Schmid-Egger (2004), they key out with B. anatolicus DE BEAUMONT (key nr. 41.). In direct comparisation, clypeus of B. rhodius is somewhat longer than in B. anatolicus, but it is not sure weather this character is confirmed. I could only examine one ‘true’ female from Karpathos. Remaining females may confused with B. anatolicus, and distribution pattern of both species overlap in Western Turkey and the Aegaian Islands. So for the moment, distinction of B. anatolicus and B. rhodius female Turkey is not possible.
