description: Toxoplasmosis is considered as one of the most prevalent human parasitic infections that can be transmitted from mother to the fetus. The onset of toxoplasmosis during pregnancy has clinical complications including spontaneous abortion, preterm labor, stillbirth and fetal abnormalities. The aim of this study was to investigate the prevalence of Toxoplasmosis infection in pregnant women and their infants in Lorestan province, Western Iran. Blood and sera samples were collected from 98 pregnant women and their infants. All collected samples were examined for Toxoplasma gondii infection by serological tests (ELISA IgM & IgG) and PCR assay. Among the 98 samples of mother and umbilical cord prevalence of anti-Toxoplasma IgG, was 34/98 (34.69 %) and 33/98 (33.67 %), respectively. All pregnant women were negative for, anti-Toxoplasma IgM while it was found in 5/98 (5.1 %) of umbilical cords. Based on PCR analysis, Toxoplasma infection was detected in 5 (5.1 %) and 7 (7.14 %) of mother and umbilical cords, respectively. Molecular test along with evaluation of IgM (P <0.001) and IgG (P = 0.001) were significantly correlated.

description: An accurate determination of the electron correlation energy is essential for describing the structure, stability, and function in a wide variety of systems, ranging from gas-phase molecular assemblies to condensed matter and organic/inorganic interfaces. Even small errors in the correlation energy can have a large impact on the description of chemical and physical properties in the systems of interest. In this context, the development of efficient approaches for the accurate calculation of the long-range correlation energy (and hence dispersion) is the main challenge. In the last years a number of methods have been developed to augment density functional approximations via dispersion energy corrections, but most of these approaches ignore the intrinsic many-body nature of correlation effects, leading to inconsistent and sometimes even qualitatively incorrect predictions. Here we build upon the recent many-body dispersion (MBD) framework, which is intimately linked to the random-phase approximation for the correlation energy. We separate the correlation energy into short-range contributions that are modeled by semi-local functionals and long-range contributions that are calculated by mapping the complex all-electron problem onto a set of atomic response functions coupled in the dipole approximation. We propose an effective range-separation of the coupling between the atomic response functions that extends the already broad applicability of the MBD method to non-metallic materials with highly anisotropic responses, such as layered nanostructures. Application to a variety of high-quality benchmark datasets illustrates the accuracy and applicability of the improved MBD approach, which offers the prospect of first-principles modeling of large structurally complex systems with an accurate description of the long-range correlation energy.

description: $In$ $situ$ angle-resolved photoemission spectroscopy (ARPES) has been performed on SrVO$_3$ ultrathin films, which show metallic quantum well (QW) states, to unveil the origin of the anomalous mass enhancement in the QW subbands. The line-shape analysis of the ARPES spectra reveals that the strength of the electron correlation increases as the subband bottom energy approaches the Fermi level. These results indicate that the anomalous subband-dependent mass enhancement mainly arises from the quasi-one-dimensional character of confined V $3d$ states as a result of their orbital-selective quantization.

description: We show that in YIG-Pt bi-layers, which are widely used in experiments on the spin transfer torque and spin Hall effects, the spin-wave amplitude significantly decreases in comparison to a single YIG film due to the excitation of microwave eddy currents in a Pt coat. By introducing a novel excitation geometry, where the Pt layer faces the ground plane of a microstrip line structure, we suppressed the excitation of the eddy currents in the Pt layer and, thus, achieved a large increase in the transmission of the Damon-Eshbach surface spin wave. At the same time, no visible influence of an external dc current applied to the Pt layer on the spin-wave amplitude in the YIG-Pt bi-layer was observed in our experiments with YIG films of micrometer thickness.

description: The paper presents a linear stability analysis of a 1D stationary flow through a poroelastic medium. This base flow is perturbed in four ways: by longitudinal (1D) disturbances without and with mass exchange and by transversal (2D) disturbances without and with mass exchange. The eigenvalue problem for the first step field equations is solved using a finite-difference-scheme. For both disturbances without mass exchange results are confirmed by an analytical solution. We present the stability and relaxation properties in dependence on the two most important model parameters, namely the bulk and surface permeability coefficients.

description: The recent synthesis and characterization of bilayers of vitreous silica has produced valuable new information on ring sizes and distributions. In this paper, we compare the ring statistics of experimental samples with computer generated samples. The average ring size is fixed at six by topology, but the width, skewness and other moments of the distribution of ring edges are characteristics of particular samples. We examine the Aboav-Weaire law that quantifies the propensity of smaller rings to be adjacent to larger rings, and find similar results for available experimental samples which however differ somewhat from computer-generated bilayers currently. We introduce a new law for the areas of rings of various sizes.
title: Establishing beneficial roles: integrating community members into archaeological practices in Atlantic Canada

Publisher: name: Memorial University of Newfoundland

description: This master’s research seeks to understand how working with undocumented collections, private artifact collectors and avocational archaeologists benefits the field of archaeology. Governmental policies related to the act of private artifact collecting and avocational archaeology in Atlantic Canada are examined. By revisiting these policies and legislation, archaeologists and non-archaeologists can begin discussing what roles private collectors and avocational archaeologists have to play in professional archaeological methodology and interpretation. Case studies are presented from Canada, England, Taiwan, the United States of America and Wales to demonstrate the significant contribution to the global archaeological record from responsible private collectors, avocational archaeologists and community museums. The need for collaboration between professional archaeologists and non-archaeologists, is heavily emphasized based on the need to improve the discipline methodologically, theoretically and ethically. Fieldwork and museum work was completed in North West River, Labrador, to produce 3D models of Tshiashinnu artifacts and to demonstrate what role community museums have in collaborating with archaeologists. The results of this research demonstrate that the most effective 3D scanning or photogrammetry equipment that a non-archaeologist can use to produce 3D models are Android or iOS applications that are user-friendly affordable. Statistical data was collected from an online survey to gather information related to different stakeholder positions on the involvement of private collectors and avocational archaeologists in the documentation of cultural material and heritage sites. There were 14 multiple-choice questions and 171 participants who answered the survey questionnaire. Over 94% of survey respondents answered that they were in favour of collaborating with private artifact collectors. Based on survey results, this demonstrates that many more contemporary archaeologists are in favour of collaborating with private artifact compared to those who are opposed to it. By collaborating with non-archaeologists such as responsible private artifact collectors and institutions like private museums and using 3D scanning technologies, archaeologists can help digitize and document archaeological collections held in private collections or community museums. We can then make these collections more accessible and share them with wider audiences. This benefits archaeology as it becomes more inclusive to those who are not trained in archaeological methodology or theory.

description: Subwavelength semiconductor nanowires have recently attracted interest for photonic applications because they possess various unique optical properties and offer great potential for miniaturizing devices. However, realizing tight light confinement or efficient coupling with photonic circuits is not straightforward and remains a challenge. Here we show that a high Q nanocavity can be created by placing a single III/V semiconductor nanowire with a diameter of under 100 nm in a grooved waveguide in a Si photonic crystal, by means of nanoprobe manipulation. We observe very fast spontaneous emission (91 ps) from nanowires accelerated by the strong Purcell enhancement in nanocavities, which proves that very strong light confinement can be achieved. Furthermore, this system enables us to move the nanocavity anywhere along the waveguide. This configuration provides a significant degree of flexibility in integrated photonics and permits the addition and displacement of various functionalities of III/V nanocavity devices in Si photonic circuits.

We show that the ground state projection and the ground state energy are analytic functions of the coupling constant in a cone with apex at the origin, provided a mild infrared assumption holds. To show the result operator theoretic renormalization is used and extended to degenerate situations.

description: Phosphorus ($^{31}$P), which is essential for life, is thought to be synthesized in massive stars and dispersed into interstellar space when these stars explode as supernovae (SNe). Here we report on near-infrared spectroscopic observations of the young SN remnant Cassiopeia A, which show that the abundance ratio of phosphorus to the major nucleosynthetic product iron ($^{56}$Fe) in SN material is up to 100 times the average ratio of the Milky Way, confirming that phosphorus is produced in SNe. The observed range is compatible with predictions from SN nucleosynthetic models but not with the scenario in which the chemical elements in the inner SN layers are completely mixed by hydrodynamic instabilities during the explosion.

description: Essex-Lopresti injuries are characterized by injuries to the proximal radio-ulnar joint, the distal radio-ulnar joint, and the interosseous membrane. This can lead to osteoarthritis, impaction syndrome, or instability. If all three structures are injured and lead to instability, the situation is almost unmanageable and many times ends in a one-bone forearm. In this article, we demonstrate a new way to reconstruct the proximal and distal radio-ulnar joint with two patient-specific coupled prostheses. These have been developed with the biomechanical conditions of the forearm in mind, where there are very large forces between the bones. As a result, we are able to present a patient previously severely restricted in the use of his hand and arm via a splint that compressed the forearm, who is now able to perform everyday activities and even light sports, such as badminton, without pain.

description: Controlling quantum critical phenomena in strongly correlated electron systems, which emerge in the neighborhood of a quantum phase transition, is a major challenge in modern condensed matter physics. Quantum critical phenomena are generated from the delicate balance between long-range order and its quantum fluctuation. So far, the nature of quantum phase transitions has been investigated by changing a limited number of external parameters such as pressure and magnetic field. We propose a new approach for investigating quantum criticality by changing the strength of quantum fluctuation that is controlled by the dimensional crossover in metallic quantum well (QW) structures of strongly correlated oxides. With reducing layer thickness to the critical thickness of metal-insulator transition, crossover from a Fermi liquid to a non-Fermi liquid has clearly been observed in the metallic QW of SrVO$_3$ by \textit{in situ} angle-resolved photoemission spectroscopy. Non-Fermi liquid behavior with the critical exponent $α = 1$ is found to emerge in the two-dimensional limit of the metallic QW states, indicating that a quantum critical point exists in the neighborhood of the thickness-dependent Mott transition. These results suggest that artificial QW structures provide a unique platform for investigating novel quantum phenomena in strongly correlated oxides in a controllable fashion.

description: In this paper, we present an OpenCL-based heterogeneous implementation of a computer vision algorithm -- image inpainting-based object removal algorithm -- on mobile devices. To take advantage of the computation power of the mobile processor, the algorithm workflow is partitioned between the CPU and the GPU based on the profiling results on mobile devices, so that the computationally-intensive kernels are accelerated by the mobile GPGPU (general-purpose computing using graphics processing units). By exploring the implementation trade-offs and utilizing the proposed optimization strategies at different levels including algorithm optimization, parallelism optimization, and memory access optimization, we significantly speed up the algorithm with the CPU-GPU heterogeneous implementation, while preserving the quality of the output images. Experimental results show that heterogeneous computing based on GPGPU co-processing can significantly speed up the computer vision algorithms and makes them practical on real-world mobile devices.

description: We describe an experiment with the modeling of urban verticalization effects on perceived safety scores as obtained with computer vision on Google Streetview data for New York City. Preliminary results suggests that for smaller buildings (between one and seven floors), perceived safety increases with building height, but that for high-rise buildings, perceived safety decreases with increased height. We also determined that while height contributing for this relation, other zonal aspects also influences the perceived safety scores, suggesting spatial structuring also influences such scores.

description: In der Sozialen Arbeit ist es vor allem die Sozialpädagogik, die Erziehungsprozesse im Rahmen ihrer Zuständigkeit für Sozialisation unterstützt. Die Heimerziehung stellt den Kernbereich der sozialpädago-gischen Praxis dar. Sozialpädagogisches Fachpersonal in stationären Einrichtungen ist täglich mit dem Führen und Umsetzen von Erziehungsprozessen konfrontiert. Die Erziehung an sich beruht auf grundlegenden Wertvorstellungen. Aufgezeigt wird, wie sich die nor-mativen Erziehungsgrundlagen erklären und welche Bedeutung sie auf die stationäre Kinder- und Ju-gendhilfe haben. Normen der Erziehung werden durch aktuelle soziale Normen geprägt. Eine normative Erziehung ist seinerseits wieder beeinflusst von sozialen Normen. Somit besteht eine Interdependenz zwischen diesen Normen. Mittels der Fachliteraturarbeit wird aufgezeigt, dass eine vertiefte Auseinandersetzung mit Erziehung und Normen sowie deren Wechselwirkung notwendig ist. Die Ergebnisse zeigen auf, dass in der sozial-pädagogischen Praxis ein diffuses und wenig greifbares Erziehungsverständnis vorherrscht. Dies wird darauf zurückgeführt, dass grössere Defizite in der theoretischen Wissensvermittlung sowie im dialogi-schen Diskurs über die Erziehung vorhanden sind.

description: Low energy consumption enabled by charge-free information transport, which is free from ohmic heating, and the ability to process phase-encoded data by nanometer-sized interference devices at GHz and THz frequencies are just a few benefits of spin-wave-based technologies. Moreover, when approaching cryogenic temperatures, quantum phenomena in spin-wave systems pave the path towards quantum information processing. In view of these applications, the lifetime of magnons$-$spin-wave quanta$-$is of high relevance for the fields of magnonics, magnon spintronics and quantum computing. Here, the relaxation behavior of parametrically excited magnons having wavenumbers from zero up to $6\cdot 10^5 \mathrm{rad~cm}^{-1}$ was experimentally investigated in the temperature range from 20 K to 340 K in single crystal yttrium iron garnet (YIG) films epitaxially grown on gallium gadolinium garnet (GGG) substrates as well as in a bulk YIG crystal$-$the magnonic materials featuring the lowest magnetic damping known so far. As opposed to the bulk YIG crystal in YIG films we have found a significant increase in the magnon relaxation rate below 150 K$-$up to 10.5 times the reference value at 340 K$-$in the entire range of probed wavenumbers. This increase is associated with rare-earth impurities contaminating the YIG samples with a slight contribution caused by coupling of spin waves to the spin system of the paramagnetic GGG substrate at the lowest temperatures.

description: The Mediterranean diet (MD) is associated with decreased risk of metabolic syndrome and gestational diabetes due to the anti-inflammatory and antioxidative properties of its components. The aim was to investigate the potential association of MD adherence (MDA) during pregnancy by mothers delivering prematurely, with intrauterine growth as expressed by neonates’ anthropometry at birth and complications of prematurity. This is a single-center, prospective, observational cohort study of 82 women who delivered preterm singletons at post conceptional age (PCA) ≤ 34 weeks and their live-born neonates. Maternal and neonatal demographic and clinical data were recorded. All mothers filled in a food frequency questionnaire, and the MDA score was calculated. Based on 50th centile of MD score, participants were classified into high-MDA and low-MDA groups. The low-MDA mothers had significantly higher pregestational BMI and rates of overweight/obesity (odd ratios (OR) 3.5) and gestational hypertension/preeclampsia (OR 3.8). Neonates in the low-MDA group had significantly higher incidence of intrauterine growth restriction (IUGR) (OR 3.3) and lower z-scores of birth weight and BMI. Regarding prematurity-related complications, the low MDA-group was more likely to develop necrotizing enterocolitis, bronchopulmonary dysplasia, and retinopathy of prematurity (OR 3.2, 1.3, and 1.6, respectively), while they were less likely to develop respiratory distress syndrome (OR 0.49), although the differences were not statistically significant. However, adjustment for confounders revealed MDA as a significant independent predictor of hypertension/preeclampsia, IUGR, birth weight z-score, necrotizing enterocolitis, and bronchopulmonary dysplasia. High MDA during pregnancy may favorably affect intrauterine growth and certain acute and chronic complications of prematurity as well as maternal hypertension/preeclampsia.

description: For each prime $p$, let $I_p \subset \mathbb{Z}/p\mathbb{Z}$ denote a collection of residue classes modulo $p$ such that the cardinalities $|I_p|$ are bounded and about $1$ on average. We show that for sufficiently large $x$, the sifted set $\{ n \in \mathbb{Z}: n \pmod{p} \not \in I_p \hbox{ for all }p \leq x\}$ contains gaps of size at least $x (\log x)^δ $ where $δ>0$ depends only on the density of primes for which $I_p\ne \emptyset$. This improves on the "trivial" bound of $\gg x$. As a consequence, for any non-constant polynomial $f:\mathbb{Z}\to \mathbb{Z}$ with positive leading coefficient, the set $\{ n \leq X: f(n) \hbox{ composite}\}$ contains an interval of consecutive integers of length $\ge (\log X) (\log\log X)^δ$ for sufficiently large $X$, where $δ>0$ depends only on the degree of $f$.

Recently, we reported on an enhanced decay of a parametrically induced Bose-Einstein condensate (BEC) of magnons caused by a supercurrent outflow of the BEC phase from the locally heated area of a room temperature magnetic film. Here, we present the direct experimental observation of a long-distance spin transport in such a system. The condensed magnons being pushed out from the potential well within the heated area form a density wave, which propagates through the BEC many hundreds of micrometers in the form of a specific second sound pulse - Bogoliubov waves - and is reflected from the sample edge. The discovery of the long distance supercurrent transport in the magnon BEC further advances the frontier of the physics of quasiparticles and allows for the application of related transport phenomena for low-loss data transfer in perspective magnon spintronics devices.

description: We report the experimental realization of a space-time crystal with tunable periodicity in time and space in the magnon Bose-Einstein Condensate (BEC), formed in a room-temperature Yttrium Iron Garnet (YIG) film by radio-frequency space-homogeneous magnetic field. The magnon BEC is prepared to have a well defined frequency and non-zero wavevector. We demonstrate how the crystalline "density" as well as the time and space textures of the resulting crystal may be tuned by varying the experimental parameters: external static magnetic field, temperature, thickness of the YIG film and power of the radio-frequency field. The proposed space-time crystals provide a new dimension for exploring dynamical phases of matter and can serve as a model nonlinear Floquet system, that brings in touch the rich fields of classical nonlinear waves, magnonics and periodically driven systems.
Soziokultur in der Nachbarschaft: Nachbarschaftsnetzwerke in benachteiligten Quartieren der Agglomeration aus Sicht der Soziokulturellen Animation am Beispiel des Riethofquartiers in Opfikon

description: Nachbarschaftsnetzwerke sind soziale Räume, die zu den Ressourcen und zum Sozialkapital der Beteiligten zählen. Diese Ressourcen sind insbesondere in Quartieren wesentlich, die über wenig Infrastruktur verfügen, als unattraktiv gelten und eine hohe Anzahl Personen mit niedrigem sozioökonomischem Status aufweisen. Ein solch benachteiligtes Quartier ist das Riethofquartier in der Zürcher Gemeinde Opfikon, die dem suburbanen Raum – auch Agglomeration genannt – angehört. Anhand dieses Beispiels untersucht die vorliegende Arbeit die Frage, wie Nachbarschaftsnetzwerke in benachteiligten Quartieren der Agglomeration beschaffen sind und welcher Handlungsbedarf für die Soziokulturelle Animation besteht. Nach einer teilstrukturierten Beobachtung werden die nachbarschaftlichen Netzwerke in drei Leitfaden-Interviews mit Anwohner*innen des Riethofquartiers explorativ erforscht. Diese Befragungen ergeben ein diverses Bild von Beziehungen und Ansichten zum Quartier. Es zeigt sich, dass das Erfassen und Einschätzen dieser Beziehungen anhand gängiger Kategorien und ohne Dialog mit den betroffenen Personen nicht möglich ist. Um Nachbarschaftsnetzwerke zu stärken, sind Möglichkeiten zur Vernetzung der Anwohner*innen sowie zur Identifikation mit dem eigenen Wohnort wichtig. Für die Soziokulturelle Animation empfiehlt sich ein lebensweltorientiertes Arbeiten, das auf den vorhandenen Ressourcen und der Perspektive der Quartierbevölkerung basiert. Nicht das Fördern und Formen von Beziehungen durch Fachpersonen, sondern die Teilhabe der Bewohner*innen am politischen und gesellschaftlichen Geschehen sowie an Entscheidungen, die «ihren» Sozialraum betreffen, stehen im Vordergrund.

description: The objective of this study was to assess the prevalence and sociodemographic characteristics of cesarean section in Ethiopia. We used data collected for Ethiopia Demographic and Health Surveys (DHS) conducted in 2000, 2005, 2011, and 2016. A two-stage, stratified, clustered random sampling design was used to gather information from women who gave birth within the 5-year period before each of the surveys. We analyzed the data to identify sociodemographic characteristics associated with cesarean section using log-Poisson regression models. The national cesarean section rate increased from 0.7% in 2000 to 1.9% in 2016, with increases across seven of the eleven administrative regions of Ethiopia. Addis Ababa had the highest cesarean section rate (21.4%) in 2016 and the greatest increase since 2000. In the adjusted analysis, women who gave birth in private health facility had a 78.0% higher risk of cesarean section (adjusted prevalence ratio (aPR) (95% CI) 1.78 (1.22, 2.58)) compared with women who gave birth in public health facility. Having four or more births was associated with a lower risk of cesarean section compared with first births (aPR (95% CI) 0.36 (0.16, 0.79)). The Ethiopian national cesarean section rate is about 2%, but the rate varies widely among administrative regions, suggesting unequal access. Cesarean sections were highest among urban mothers, first births, births to women with higher education, and births to women from the richest quintile of household wealth.

description: Introduction: The Purpose of the present study was to assess the outcome of anterior cruciate ligament reconstruction (ACLR) with an accelerated rehabilitation protocol and to compare it to a conservative rehabilitation protocol. It was hypothesized that an accelerated rehabilitation protocol, including brace-free early weight bearing, would result in a higher rate of recurrent instability and revision surgery compared to a conservative rehabilitation protocol. Methods: From 2016 to 2017, two different rehabilitation protocols for isolated ACLR were used at a high-volume knee surgery center. A total of 65 consecutive patients with isolated hamstring ACLR, of whom n = 33 had been treated with an accelerated (AccRehab) and n = 32 with a conservative rehabilitation protocol (ConRehab), were retrospectively included in the study. Patients were evaluated for recurrent instability, revision surgery, and other complications at a mean follow-up period of 64 ± 7.4 months. In addition, Tegner Activity Scale, Lysholm Score, and IKDC-subjective Score were evaluated. Statistical comparison between the two groups was performed utilizing Fisher’s exact test and Student’s t-test. Results: Mean age (29.3 vs. 26.6 years) and preoperative Tegner Score (6.4 vs. 5.9) were comparable between both groups. At 64 ± 7.4 months after ACLR, six cases of recurrent instability were reported in the AccRehab group (18%) in comparison to three cases (9%) in the ConRehab group (p = n.s.). There was no significant difference regarding revision surgery and further complications. Furthermore, no significant difference was found between both groups regarding Tegner (5.5 ± 1.9 vs. 5.5 ± 1.2), Lysholm (93.6 ± 6.3 vs. 89.3 ± 10.7), and IKDC score (89.7 ± 7.9 vs. 86.7 ± 12.1). Conclusion: No significant disadvantage of an accelerated rehabilitation protocol following ACLR was found in terms of recurrent instability rate, revision surgery, or patient-reported outcome. However, a trend towards a higher reinstability rate was found for an accelerated rehabilitation protocol. Future level one trials evaluating brace-free early weight bearing following ACLR are desirable.

description: Resonant enhancement of spin Seebeck effect (SSE) due to phonons was recently discovered in Y3Fe5O12 (YIG). This effect is explained by hybridization between the magnon and phonon dispersions. However, this effect was observed at low temperatures and high magnetic fields, limiting the scope for applications. Here we report observation of phonon-resonant enhancement of SSE at room temperature and low magnetic field. We observed in Lu2BiFe4GaO12 and enhancement 700 % greater than that in a YIG film and at very low magnetic fields around 10-1 T, almost one order of magnitude lower than that of YIG. The result can be explained by the change in the magnon dispersion induced by magnetic compensation due to the presence of non-magnetic ion substitutions. Our study provides a way to tune the magnon response in a crystal by chemical doping with potential applications for spintronic devices.

description: We have prepared high-quality epitaxial thin films of CaRuO$_3$ with residual resistivity ratios up to 55. Shubnikov-de Haas oscillations in the magnetoresistance and a $T^2$ temperature dependence in the electrical resistivity only below 1.5 K, whose coefficient is substantially suppressed in large magnetic fields, establish CaRuO$_3$ as a Fermi liquid (FL) with anomalously low coherence scale. Non-Fermi liquid (NFL) $T^{3/2}$ dependence is found between 2 and 25 K. The high sample quality allows access to the intrinsic electronic properties via THz spectroscopy. For frequencies below 0.6 THz, the conductivity is Drude-like and can be modeled by FL concepts, while for higher frequencies non-Drude behavior, inconsistent with FL predictions, is found. This establishes CaRuO$_3$ as a prime example of optical NFL behavior in the THz range.
