description: We present VLT-ISAAC medium resolution spectroscopy of the HH34 and HH1 jets. Our aim is to derive the kinematics and the physical parameters and to study how they vary with jet velocity. We use several important diagnostic lines such as [FeII] 1.644um, 1.600um and H2 2.122um. In the inner jet region of HH34 we find that both the atomic and molecular gas present two components at high and low velocity. The [FeII] LVC in HH34 is detected up to large distances from the source (>1000 AU), at variance with TTauri jets. In H2 2.122um, the LVC and HVC are spatially separated. We detect, for the first time, the fainter red-shifted counterpart down to the central source. In HH1, we trace the jet down to ~1" from the VLA1 driving source: the kinematics of this inner region is again characterised by the presence of two velocity components, one blue-shifted and one red-shifted with respect to the source LSR velocity. In the inner HH34 jet region, ne increases with decreasing velocity. Up to ~10" from the driving source, and along the whole HH1 jet an opposite behaviour is observed instead, with ne increasing with velocity. In both jets the mass flux is carried mainly by the high-velocity gas. A comparison between the position velocity diagrams and derived electron densities with models for MHD jet launching mechanisms has been performed for HH34. While the kinematical characteristics of the line emission at the jet base can be, at least qualitatively, reproduced by both X-winds and disc-wind models, none of these models can explain the extent of the LVC and the dependence of electron density with velocity that we observe. It is possible that the LVC in HH34 represents gas not directly ejected in the jet but instead denser ambient gas entrained by the high velocity collimated jet.

Holotype worker, MALAYSIA: Borneo, Sabah, Danum Valley, West Trail P 1, 250 m, ii.1999 (C. Brühl) (USNM); 2 paratype workers, same locality as holotype (ANIC; USNM); 1 paratype worker, MALAYSIA: Borneo, Sabah, Sepiok Forest Reserve, 60 m, ii.2000 (C. Brühl) (USNM).
 Worker. Measurements (n=3): TL: 2.98–3.36; HW: 0.77–0.82; HL: 0.81–0.89; SL: 1.07–1.11; WL: 1.1–1.26; GL: 1–1.21. Indices: CI: 91–96; SI: 136–140
Head brown, with scapes and mandibles lighter and funiculi much lighter becoming brownish-yellow; head about as long as broad. Cuticular surface shiny and weakly rugoreticulate, with scattered erect setae, with only small areas of pubescence along clypeal margin. Scapes with scattered pubescence and erect setae; pubescence more abundant distally. Mesosoma light brown, shiny, with legs slightly lighter. Scattered erect setae of varying lengths concentrated on posterior pronotum and anterior mesonotum. Pronotum rises at about 45° toward mesonotum; propodeum dorsum rounded, dome-like; declivity short, but steep. Petiole triangular, inclined forward, with posterior face longer than anterior face; gaster darker brown than mesosoma, with erect setae and no pubescence; cuticular surface shiny and weakly rugoreticulate.
 Etymology: The species epithet is Latin for different, in reference to its separation from E. wittei.
 Discussion: E. variegata workers are most likely to be confused with E. wittei. The two species can be separated based on the fact that E. variegata is lighter in color, has scattered pubescence on the scapes, becoming dense distally, and longer erect setae on the gaster than those of E. wittei.

description: The reliability of AlGaN/GaN HEMTs adopting Fe and C co-doping, with high and low carbon doping concentration was investigated by means of different stress tests. Firstly, DC and pulsed I-V characterization at room temperature are discussed, then drain step stress tests at different gate voltages are compared, afterwards, the constant stress at different bias points are discussed. Results show that the high C HEMTs showed reduced DIBL, smaller leakage current, as well as decreased electric field, leading to an improved robustness during on-state stress testing, with respect to the reference ones. Failure modes during constant voltage stress consists in a decrease of drain current and transconductance, accelerated by temperature and electric field.

description: The objective of this study was to compare the motor competence of children in different environments, namely private and public schools. This study looked at a representative sample of preschool children (3-5 years) the city of Recife-PE. We included all subjects who completed the Test of Gross Motor Development - 2. The groups were made up of children from private schools (n = 161; 95 boys), and public (n = 131; 63 boys). Data analysis used analysis of variance (ANOVA Two-Way), by adopting a p ≤ 0.05. In general, private school children had superior performance. When analyzed gender differences, boys were higher. The results suggest that children of different school environments appear to differ in their motor competence. Therefore, we suggest that future studies assessing the characteristics of space used and the intensity and duration of activities that children are involved.

description: Synthetic Aperture Radar (SAR) images are prone to be contaminated by noise, which makes it very difficult to perform target recognition in SAR images. Inspired by great success of very deep convolutional neural networks (CNNs), this paper proposes a robust feature extraction method for SAR image target classification by adaptively fusing effective features from different CNN layers. First, YOLOv4 network is fine-tuned to detect the targets from the respective MF SAR target images. Second, a very deep CNN is trained from scratch on the moving and stationary target acquisition and recognition (MSTAR) database by using small filters throughout the whole net to reduce the speckle noise. Besides, using small-size convolution filters decreases the number of parameters in each layer and, therefore, reduces computation cost as the CNN goes deeper. The resulting CNN model is capable of extracting very deep features from the target images without performing any noise filtering or pre-processing techniques. Third, our approach proposes to use the multi-canonical correlation analysis (MCCA) to adaptively learn CNN features from different layers such that the resulting representations are highly linearly correlated and therefore can achieve better classification accuracy even if a simple linear support vector machine is used. Experimental results on the MSTAR dataset demonstrate that the proposed method outperforms the state-of-the-art methods.

description: The properties of nuclei embedded in an electron gas are studied within the relativistic mean-field approach. These studies are relevant for nuclear properties in astrophysical environments such as neutron-star crusts and supernova explosions. The electron gas is treated as a constant background in the Wigner-Seitz cell approximation. We investigate the stability of nuclei with respect to alpha and beta decay. Furthermore, the influence of the electronic background on spontaneous fission of heavy and superheavy nuclei is analyzed. We find that the presence of the electrons leads to stabilizing effects for both $α$ decay and spontaneous fission for high electron densities. Furthermore, the screening effect shifts the proton dripline to more proton-rich nuclei, and the stability line with respect to beta decay is shifted to more neutron-rich nuclei. Implications for the creation and survival of very heavy nuclear systems are discussed.

description: We demonstrate spin injection into a graphene thin film with high reliability by using non-local magnetoresistance (MR) measurements, in which the electric current path is completely separated from the spin current path. Using these non-local measurements, an obvious MR effect was observed at room temperature; and the MR effect was ascribed to magnetization reversal of ferromagnetic electrodes. This result is a direct demonstration of spin injection into a graphene thin film. Furthermore, this is the first report of spin injection into molecules at room temperature.

description: The flux and the spectral index in X-ray energy band from the knots of M87 jet as observed by {\it{Chandra}} indicate a possible synchrotron origin but cannot be explained by simple one zone models with continuous injection of non-thermal electrons. In this letter we propose a two-zone model to explain the observed spectra of the knots of M87 jet. We consider the synchrotron emission from a region with tangled magnetic field where relativistic non-thermal electrons are continuously injected in from an associated acceleration region. The acceleration region is assumed to be compact zone possibly around a shock front. A power-law distribution of electron is injected into the acceleration region and are accelerated to a maximum energy determined by the acceleration time scale and the loss processes. With the present model we are able to explain the overall broadband features of the knots of M87 jet. Also the present model predicts a change in spectral index at ultraviolet energies and future observations at these energies can be used to constrain the parameters involved in the model.

description: Inspiral of binary black holes occurs over a time-scale of many orbits, far longer than the dynamical time-scale of the individual black holes. Explicit evolutions of a binary system therefore require excessively many time steps to capture interesting dynamics. We present a strategy to overcome the Courant-Friedrichs-Lewy condition in such evolutions, one relying on modern implicit-explicit ODE solvers and multidomain spectral methods for elliptic equations. Our analysis considers the model problem of a forced scalar field propagating on a generic curved background. Nevertheless, we encounter and address a number of issues pertinent to the binary black hole problem in full general relativity. Specializing to the Schwarzschild geometry in Kerr-Schild coordinates, we document the results of several numerical experiments testing our strategy.

description: Kondo insulators have recently aroused great interest because they are promising materials that host a topological insulator state caused by the strong electron interactions. Moreover, recent observations of the quantum oscillations in the insulating state of Kondo insulators have come as a great surprise. Here, to investigate the surface electronic state of a prototype Kondo insulator YbB$_{12}$, we measured transport properties of single crystals and microstructures. In all samples, the temperature dependence of the electrical resistivity is insulating at high temperatures and the resistivity exhibits a plateau at low temperatures. The magnitude of the plateau value decreases with reducing sample thickness, which is quantitatively consistent with the surface electronic conduction in the bulk insulating YbB$_{12}$. Moreover, the magnetoresistance of the microstructures exhibits a weak-antilocalization effect at low field. These results are consistent with the presence of topologically protected surface state, suggesting that YbB$_{12}$ is a candidate material of the topological Kondo insulator. The high field resistivity measurements up to $μ_0H$ = 50 T of the microstructures provide supporting evidence that the quantum oscillations of the resistivity in YbB$_{12}$ occurs in the insulating bulk.

description: With the present study, we aimed to investigate the task complexity effects on the performance of a coincidence timing task in individuals with Down syndrome. The experimental group was consisted by 26 subjects with Down syndrome, 20 years old (± 5), and classified as mild or moderate in International Classification of Functioning and Health. Each participant in the experimental group was matched by in function of gender and age with a participant in a control group without Down syndrome. Both groups performed a coincident timing task, in which the participant had different levels of structural and functional complexity. Performance measure was derived from the consistency (absolute error), accuracy (variable error) and direction of response (constant error). Individuals with Down syndrome presented spatiotemporal organization impairments related to the difficulty in dealing with motor demand in order to interact with the perceptive demand. They also experienced difficulty in adapt to task complexity, causing performance error in the task. Individuals with Down syndrome have deficits in perceptive and space-time organization, and this phenomenon may be explained by the difficulty in integrating perceptive stimulus to motor actions with a high number of elements involved.

Talking among grade seven peers as an influence on the teaching of drawing and on the acquisition of drawing skill
Creators: name: Bevis, Vivian
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of the study was to find out more about verbal and visual aspects of teaching art and learning to draw in the classroom. It was to determine what influence language has on visual processes in drawing and to examine effects of talking and verbal thinking on the acquisition of drawing skills of pre-adolescent students in grade seven. The study consisted of a 10-week drawing course for four classes of grade seven students in an elementary school in Vancouver, British Columbia. Instruction was the same for all classes except that in two of the classes students were permitted to talk to each other while drawing and in two classes students were instructed not to talk while drawing. Data were collected and observations recorded using scores on drawing tests, student evaluations, drawing surveys and teacher logs. Although scores on drawing tests showed little difference between the two groups, consistent observations indicated that students did not talk and draw at the same time. Students who talked stopped drawing, completed fewer drawings, made less frequent reference to the model and followed fewer directions. When comparing the work of the two groups, teacher attitude toward the talking group reflected more dissatisfaction because of the higher incidence of incomplete work and the necessity of having to raise the voice in order to be heard.

description: Traditionally, fault detection and isolation community has used system dynamic equations to generate diagnosers and to analyze detectability and isolability of the dynamic systems. Model-based fault detection and isolation methods use system model to generate a set of residuals as the bases for fault detection and isolation. However, in many complex systems it is not feasible to develop highly accurate models for the systems and to keep the models updated during the system lifetime. Recently, data-driven solutions have received an immense attention in the industries systems for several practical reasons. First, these methods do not require the initial investment and expertise for developing accurate models. Moreover, it is possible to automatically update and retrain the diagnosers as the system or the environment change over time. Finally, unlike the model-based methods it is straight forward to combine time series measurements such as pressure and voltage with other sources of information such as system operating hours to achieve a higher accuracy. In this paper, we extend the traditional model-based fault detection and isolation concepts such as residuals, and detectable and isolable faults to the data-driven domain. We then propose an algorithm to automatically generate residuals from the normal operating data. We present the performance of our proposed approach through a comparative case study.

description: Decreased range of motion (ROM) of the ankle and dorsiflexor strength due to the aging process has been associated with increased risk of trips and falls. However, the impact of dual-task on the ankle ROM in elderly is not clear. It was our objective to evaluate the ankle ROM in community elderly during usual gait and two simultaneous task conditions (functional and cognitive). Thirty-two community elderly (66.8 ± 4.7 years) of both sexes, non-fallers, who had independent walking were recruited. The dorsiflexion and plantar flexion of the ankle were assessed in three situations: usual gait, gait with functional task and gait with cognitive task, using 8 cameras Qualisys Pro-reflex Oqus 300®. Analysis of variance (ANOVA) were applied and comparisons were made by Newman-Keuls using SPSS (version 16.0) adopting a significance level of 5% (p£ 0.05). There were no differences among tasks (p> 0.05) in the dorsiflexion and plantar flexion in the elderly, however, during the usual gait the dorsiflexion ROM of the elderly was lower than the normative values described in literature. The performance of tasks during walking have no influence on ankle ROM in non-fallers community-elderly. However, more studies including older adults who have previously fallen are necessary.

description: An integrable semi-discretization of the Camassa-Holm equation is presented. The keys of its construction are bilinear forms and determinant structure of solutions of the CH equation. Determinant formulas of $N$-soliton solutions of the continuous and semi-discrete Camassa-Holm equations are presented. Based on determinant formulas, we can generate multi-soliton, multi-cuspon and multi-soliton-cuspon solutions. Numerical computations using the integrable semi-discrete Camassa-Holm equation are performed. It is shown that the integrable semi-discrete Camassa-Holm equation gives very accurate numerical results even in the cases of cuspon-cuspon and soliton-cuspon interactions. The numerical computation for an initial value condition, which is not an exact solution, is also presented.

description: The objective of this study was to analyse the changes on gross motor development after five (T5), ten (T10) and 30 (T30) months of swimming or soccer practice. The study sample consists of 33 preschool-aged boys (4.8±0.5 yrs.): 11 soccer practitioners; 11 swimming practitioners; 11 controls (no previous involvement in sports). The Test of Gross Motor Development–Second Edition was used to assess common gross motor skills (locomotion, object control skills). Both experimental groups improved significantly in their gross motor quotient and the standard scores for locomotion and object control skills between T5 and T10. At T10, all soccer practitioners have already reached the maximum descriptive rating for the gross motor quotient. Between T10 and T30, swimming practitioners were able to improve the standard scores for object control skills. Main results showed a positive impact of swimming and soccer participation in motor proficiency.

description: Sytematic uncertainties to the single top production cross section measurement at the ATLAS experiment has been studied. Different sources of systematic uncertainties such as detector luminosity, jet energy calibration, SM background normalization, PDF parameterization and others have been considered. Large scale Monte-Carlo events simulation has been performed to estimate the contribution of each source in the overall uncertainty. The study was done for cut based analysis as well as for multivariate analysis of the single top measurements in ATLAS. The total systematic uncertainties of the single top cross-section measurements in its three production channels have been estimated at 1 $\mathrm{fb}^{-1}$ and 10 $\mathrm{fb}^{-1}$ integrated luminosity of the LHC.

description: Neural Machine Translation has shown promising performance in literary texts. Since literary machine translation has not yet been researched for the English-toSlovene translation direction, this paper aims to fulfill this gap by presenting a comparison among bespoke NMT models, tailored to novels, and Google Neural Machine Translation. The translation models were evaluated by the BLEU and METEOR metrics, assessment of fluency and adequacy, and measurement of the postediting effort. The findings show that all evaluated approaches resulted in an increase in translation productivity. The translation model tailored to a specific author outperformed the model trained on a more diverse literary corpus, based on all metrics except the scores for fluency. However, the translation model by Google still outperforms all bespoke models. The evaluation reveals a very low inter-rater agreement on fluency and adequacy, based on the kappa coefficient values, and significant discrepancies between posteditors. This suggests that these methods might not be reliable, which should be addressed in future studies.

description: High penetrations of photovoltaic (PV) systems can cause severe voltage quality problems in distribution networks. This paper proposes a distributed control strategy based on the dynamic formation of coalitions to coordinate a large number of PV inverters for voltage regulation. In this strategy, a rule-based coalition formation scheme deals with the zonal voltage difference caused by the uneven integration of PV capacity. Under this scheme, PV inverters form into separate voltage regulation coalitions autonomously according to local, neighbor as well as coalition voltage magnitude and regulation capacity information. To coordinate control within each coalition, we develop a feedback-based leader-follower consensus algorithm which eliminates the voltage violations caused by the fast fluctuations of load and PV generation. This algorithm allocates the required reactive power contribution among the PV inverters according to their maximum available capacity to promote an effective and fair use of the overall voltage regulation capacity. Case studies based on realistic distribution networks and field-recorded data validate the effectiveness of the proposed control strategy. Moreover, comparison with a centralized network decomposition-based scheme shows the flexibility of coalition formation in organizing the distributed PV inverters. The robustness and generalizability of the proposed strategy are also demonstrated.

description: We present theoretical schemes for performing high-fidelity one- and two-qubit pulsed gates for a superconducting flux qubit. The "IBM qubit" consists of three Josephson junctions, three loops, and a superconducting transmission line. Assuming a fixed inductive qubit-qubit coupling, we show that the effective qubit-qubit interaction is tunable by changing the applied fluxes, and can be made negligible, allowing one to perform high fidelity single qubit gates. Our schemes are tailored to alleviate errors due to 1/f noise; we find gates with only 1% loss of fidelity due to this source, for pulse times in the range of 20-30ns for one-qubit gates (Z rotations, Hadamard), and 60ns for a two-qubit gate (controlled-Z). Our relaxation and dephasing time estimates indicate a comparable loss of fidelity from this source. The control of leakage plays an important role in the design of our shaped pulses, preventing shorter pulse times. However, we have found that imprecision in the control of the quantum phase plays the major role in the limitation of the fidelity of our gates.

description: In this paper we carry out a quantitative analysis of the three-body systems and map them as a function of decaying time and intial conguration, look at this problem as an example of a simple deterministic system, and ask to what extent the orbits are really predictable. We have investigated the behavior of about 200 000 general Newtonian three body systems using the simplest initial conditions. Within our resolution these cover all the possible states where the objects are initially at rest and have no angular momentum. We have determined the decay time-scales of the triple systems and show that the distribution of this parameter is fractal in appearance. Some areas that appear stable on large scales exhibit very narrow strips of instability and the overall pattern, dominated by resonances, reminds us of a traditional Maasai warrior shield. Also an attempt is made to recover the original starting conguration of the three bodies by backward integration. We find there are instances where the evolution to the future and to the past lead to different orbits, in spite of time symmetric initial conditions. This implies that even in simple deterministic systems there exists an Arrow of Time.

description: Spin-orbit Mott insulators composed of $t_{2g}^4$ transition metal ions may host excitonic magnetism due to the condensation of spin-orbital $J=1$ triplons. Prior experiments suggest that the $4d$ antiferromagnet Ca$_{2}$RuO$_{4}$ embodies this notion, but a $J = 0$ nonmagnetic state as a basis of the excitonic picture remains to be confirmed. We use Ru $L_3$-edge resonant inelastic x-ray scattering to reveal archetypal $J$ multiplets with a $J=0$ ground state in the cubic compound K$_{2}$RuCl$_{6}$, which are well described within the $LS$-coupling scheme. This result highlights the critical role of unquenched orbital moments in $4d$-electron compounds and calls for investigations of quantum criticality and excitonic magnetism on various crystal lattices.

The crucial importance of the $t_{2g}$--$e_g$ hybridization in transition metal oxides

description: We studied the influence of the trigonal distortion of the regular octahedron along the (111) direction, found in the $\rm CoO_2$ layers. Under such a distortion the $t_{2g}$ orbitals split into one $a_{1g}$ and two degenerated $e_g^\prime$ orbitals. We focused on the relative order of these orbitals. Using quantum chemical calculations of embedded clusters at different levels of theory, we analyzed the influence of the different effects not taken into account in the crystalline field theory; that is metal-ligand hybridization, long-range crystalline field, screening effects and orbital relaxation. We found that none of them are responsible for the relative order of the $t_{2g}$ orbitals. In fact, the trigonal distortion allows a mixing of the $t_{2g}$ and $e_g$ orbitals of the metallic atom. This hybridization is at the origin of the $a_{1g}$--$e_g^\prime$ relative order and of the incorrect prediction of the crystalline field theory.

description: Charge carriers in a graphene sheet, a single layer of graphite, exhibit much distinctive characteristics to those in other two-dimensional electronic systems because of their chiral nature. In this report, we focus on the observation of weak localization in a graphene sheet exfoliated from a piece of natural graphite and nano-patterned into a Hall-bar geometry. Much stronger chiral-symmetry-breaking elastic intervalley scattering in our graphene sheet restores the conventional weak localization. The resulting carrier-density and temperature dependence of the phase coherence length reveal that the electron-electron interaction including a direct Coulomb interaction is the main inelastic scattering factor while electron-hole puddles enhance the inelastic scattering near the Dirac point.

description: Additive manufacturing, called 3D printing, starts to play an unprecedented role in developing many applications in industrial or personalized products. The conductive composite structures require additional treatment to achieve an electroactive surface useful for electrochemical devices. In this paper, the surfaces of carbon black/poly(lactic acid) CB-PLA printouts were activated by electrolysis or enzymatic digestion with proteinase K, or a simultaneous combination of both. Proposed modification protocols allowed for tailoring electrochemically active surface area and electron transfer kinetics determined by electrochemical techniques (CV, EIS) with [Fe(CN)6]4-/3- redox probe. The X-ray photon spectroscopy and SEM imaging were applied to determine the delivered surface chemistry. The CB-PLA hydrolysis in alkaline conditions and under anodic polarization greatly impacts the charge transfer kinetics. The enzymatic hydrolysis of PLA with proteinase K has led to highly efficient results yet requiring an unsatisfactory prolonged activation duration of 72 h, efficiently reduced by the electrolysis carried out in the presence of the enzyme. Our studies hint that the activation protocol originates from surface electropolymerization rather than synergistic interaction between electrolysis and enzymatic hydrolysis. The detailed mechanism of CB-PLA hydrolysis supported by electrolysis has been elaborated since it pawed a new route towards a time-efficient and environmentally-friendly activation procedure.

The introduction and historical development of social studies in the curriculum of the public schools of British Columbia
Creators: name: Dawson, Elisabeth
Publisher: name: University of British Columbia
Year: 2010

description: Social studies first appeared in the official literature of the British Columbia Department of Education in 1927 when it replaced history and geography in the curriculum of the newly established junior high schools. During the depression the "new curriculum" introduced the concept of social studies to the entire public school system. Though the content of the social studies courses remained primarily history, with some geography in the elementary schools, the change in name to social studies allowed the goals to be oriented around behavior—rather than content. Through the goals of social studies, the concept of the 'socialization' of the individual was introduced into the public school system. The introduction of social studies into the curriculum was without controversy despite such politically-oriented aims, for many teachers, having experienced, directly or indirectly, the effects of World War I, saw social studies as part of a child-centred curriculum which would help students find a better life. In reality, though some experimentation did take place, very little changed in the classroom and most teachers and students noticed little difference. While there have been no fundamental changes in the content of the social studies curriculum, changes are to be found in the goals. Social studies was introduced into the curriculum to transmit citizen ship; to create a good Canadian citizen who would maintain British traditions. After World War II, though the goals remained citizenship transmission, the concept of a good citizen changed. A good citizen was seen as one who was not only a good Canadian citizen but also a good "world" citizen. During the 1950's the goal of formal citizenship transmission, as the "raison d'être" of social studies, gradually changed. Beginning with the revision of the elementary curriculum in 1957 a more traditional view of education held that knowledge was an important goal of social studies. The concept of social studies as a social science finally developed in the revisions for both elementary and high school which began in 1966. As the concept of social studies as a social science developed there was a demand for the inclusion of more geography in the curriculum. This coincided with the growth of departments of geography in Canadian universities, and resulted in the inclusion of geography in the 1966-68 revisions of the social studies curriculum on a basis equal to that of history. Until this last revision, the social studies curriculum had been based almost entirely on history though the definition of social studies had always included a list of the social sciences from which social studies would be drawn. Since this list was almost entirely ignored by the teachers who drew up the course outlines, it can be said that social studies, as defined by the Programmes of Study, has not been taught in British Columbia.
