description: In the present paper the high-frequency induction (HFI) welding process is studied numerically. The mathematical model  comprises a harmonic vector potential formulation of the Maxwell equations and a quasi-static, convection dominated heat  equation coupled through the joule heat term and nonlinear constitutive relations. Its main novelties are twofold:  A new analytic  approach permits to compute  a spatially varying feed velocity  depending on the angle of the Vee-opening  and additional spring-back effects.  Moreover, a numerical stabilization  approach for the finite element discretization  allows to consider realistic weld-line speeds and thus a fairly comprehensive  three-dimensional simulation of the tube welding process.

description: Using the HiVIS spectropolarimeter built for the Haleakala 3.7m AEOS telescope, we have obtained a large number of high precision spectropolarimetrc observations (284) of Herbig AeBe stars collected over 53 nights totaling more than 300 hours of observing. Our sample of five HAeBe stars: AB Aurigae, MWC480, MWC120, MWC158 and HD58647, all show systematic variations in the linear polarization amplitude and direction as a function of time and wavelength near the H-alpha line. In all our stars, the H-alpha line profiles show evidence of an intervening disk or outflowing wind, evidenced by strong emission with an absorptive component. The linear polarization varies by 0.2% to 1.5% with the change typically centered in the absorptive part of the line profile. These observations are inconsistent with a simple disk-scattering model or a depolarization model which produce polarization changes centered on the emmissive core. We speculate that polarized absorption via optical pumping of the intervening gas may be the cause.

description: We study elementary low energy excitations inside a supersolid. We find that the coupling between the longitudinal lattice vibration mode and the superfluid mode leads to two longitudinal modes (one upper branch and one lower branch) inside the supersolid, while the transverse modes in the supersolid stay the same as those inside a normal solid. We also work out various experimental signatures of these novel elementary excitations by evaluating the Debye-Waller factor, density-density correlation, vortex loop-vertex loop interactions, specific heat and excess entropy from the vacancies per mole.

description: Based on the effective four-band model we analyze the spin response in the normal and superconducting states of the Fe-pnictide superconductors. While the normal state spin excitations are dominated by the continuum of the interorbital antiferromagnetic fluctuations and the intraband spin density wave fluctuations, the unconventional superconductivity yields different feedback. The resonance peak in form of the well-defined spin exciton occurs {\it only} for the interband scattering at the antiferromagnetic momentum ${\bf Q}_{AFM}$ for the $s_\pm$ (extended s-wave) superconducting order parameter and it disappears rapidly for ${\bf q} < {\bf Q}_{AFM}$. The resonance feature is extremely weak for the $d_{x^2 -y^2}$-wave order parameter due to specific Fermi surface topology of these compounds. The essential difference between $s_\pm$-wave and $d_{x^2 -y^2}$-wave symmetries for the magnetic excitations can be used for experimental determination of the superconducting wave function symmetry.

description: In this paper we consider the linear ordinary equation of the second order $$ L x(t)\equiv \ddot{x}(t) +a(t)\dot{x}(t)+b(t)x(t)=f(t), \eqno{(1)} $$ and the corresponding homogeneous equation $$ \ddot{x}(t) +a(t)\dot{x}(t)+b(t)x(t)=0. \eqno{(2)} $$ Note that $[α,β]$ is called a nonoscillation interval if every nontrivial solution has at most one zero on this interval. Many investigations which seem to have no connection such as differential inequalities, the Polia-Mammana decomposition (i.e. representation of the operator $L$ in the form of products of the first order differential operators), unique solvability of the interpolation problems, kernels oscillation, separation of zeros, zones of Lyapunov's stability and some others have a certain common basis - nonoscillation. Presumably Sturm was the first to consider the two problems which naturally appear here: to develop corollaries of nonoscillation and to find methods to check nonoscillation. In this paper we obtain several tests for nonoscillation on the semiaxis and apply them to propose new results on asymptotic properties and the exponential stability of the second order equation (2). Using the Floquet representations and upper and lower estimates of nonoscillation intervals of oscillatory solutions we deduce results on the exponential and Lyapunov's stability and instability of equation (2).

description: We investigate the effect of Pauli non-locality in the heavy-ion optical potential on sub-barrier fusion reactions. The São Paulo potential, which takes into account the Pauli non-locality and has been widely used in analyzing elastic scattering, has also recently been applied to heavy-ion fusion. However, the approximation employed in deriving the São Paulo potential, based on the Perey-Buck semi-classical treatment of neutron induced reactions, must be assessed for charged particles tunneling through a barrier. It is the purpose of this note to look into this question. We consider the widely studied system $^{16}$O + $^{208}$Pb at energies that span the barrier region from 10 MeV below to 10 MeV above. It seems that the non-locality plays a minor role. We find the São Paulo potential to be quite adequate throughout the region.

description: Superconductivity frequently appears by doping compounds that show a collective phase transition. So far, however, this has not been observed in topological materials. Here we report the discovery of superconductivity induced by Ga doping in orthorhombic Re$_{3}$Ge$_{7}$, which undergoes a second-order metal-insulator-like transition at $\sim$58 K and is predicted to have a nontrivial band topology. It is found that the substitution of Ga for Ge leads to hole doping in Re$_{3}$Ge$_{7-x}$Ga$_{x}$. As a consequence, the phase transition is gradually suppressed and disappears above $x$ = 0.2. At this $x$ value, superconductivity emerges and $T_{\rm c}$ exhibits a dome-like doping dependence with a maximum value of 3.37 K at $x$ = 0.25. First-principles calculations suggest that the phase transition in Re$_{3}$Ge$_{7}$ is associated with an electronic instability driven by Fermi surface nesting and the nontrival band topology is preserved after Ga doping. Our results indicate that Ga-doped Re$_{3}$Ge$_{7}$ provides a rare opportunity to study the interplay between superconductivity and competing electronic states in a topologically nontrivial system.

description: Motivated by the evidence in PCCO and NCCO of a magnetic quantum critical point at which Neel order is destroyed, we study the evolution with doping of the T=0 quantum phases of the electron doped cuprates. At low doping, there is a metallic Neel state with small electron Fermi pockets, and this yields a fully gapped d_{x^2-y^2} superconductor with co-existing Neel order at low temperatures. We analyze the routes by which the spin-rotation symmetry can be restored in these metallic and superconducting states. In the metal, the loss of Neel order leads to a topologically ordered `doublon metal' across a deconfined critical point with global O(4) symmetry. In the superconductor, in addition to the conventional spin density wave transition, we find a variety of unconventional possibilities, including transitions to a nematic superconductor and to valence bond supersolids. Measurements of the spin correlation length and of the anomalous dimension of the Neel order by neutron scattering or NMR should discriminate these unconventional transitions from spin density wave theory.

description: We study the response of a weakly damped vibrational mode of a nanostring resonator to a moderately strong resonant driving force. Because of the geometry of the experiment, the studied flexural vibrations lack inversion symmetry. As we show, this leads to a nontrivial dependence of the vibration amplitude on the force parameters. For a comparatively weak force, the response has the familiar Duffing form, but for a somewhat stronger force, it becomes significantly different. Concurrently there emerge vibrations at twice the drive frequency, a signature of the broken symmetry. Their amplitude and phase allow us to establish the cubic nonlinearity of the potential of the mode as the mechanism responsible for both observations. The developed theory goes beyond the standard rotating-wave approximation. It quantitatively describes the experiment and allows us to determine the nonlinearity parameters.

A descriptive analysis of helpful behaviour for assisting the widowed in bereavement
Creators: name: Easton, Jessica Louise
Publisher: name: University of British Columbia
Year: 2010

description: Widowhood and bereavement was explored in depth to determine an effective criteria for helping the widowed through bereavement, based upon their descriptive repall of the experience of grief. Fifteen adult women, who had engaged in group therapy, were interviewed. The critical incident technique was used to identify what factors hindered or facilitated the widows during grief in the two hundred and forty-one experiences collected. Each incident was categorized according to which factors were considered helpful and which factors were considered harmful. The study yielded two levels of categorization: categories and sub-categories. Five categories of helpful incidents emerged from the data which were labelled taking action, receiving support, sharing the grief, verbal reassurance and physical comfort. Five categories of hindering incidents emerged from the data which were inability to act, lack of support, feeling alone, verbal criticism and physical distress. Of these, the largest number of incidents in both the helpful and harmful categories were found in receiving support and lack of support. In the receiving support sample, perceived support whether initiated or received by the widow was experienced as helpful. In the lack of support sample, the widow expected or needed to be treated differently and when others responded in a way she did not expect the widow perceived it as lack of support. Independent judges found these categories reliable. Results are examined by comparing the data generated to relevant literature and suggesting some criteria for helping the widow through grief.

description: This work aims to provide an effective and novel solution for the treatment of infection by using nanovehicles loaded with antibiotics capable of penetrating the bacterial wall, thus increasing the antimicrobial effectiveness. These nanosystems, named "nanoantibiotics", are composed of mesoporous silica nanoparticles (MSNs), which act as nanocarriers of an antimicrobial agent (levofloxacin, LEVO) localized inside the mesopores. To provide the nanosystem of bacterial membrane interaction capability, a polycationic dendrimer, concretely the poly(propyleneimine) dendrimer of third generation (G3), was covalently grafted to the external surface of the LEVO-loaded MSNs. After physicochemical characterization of this nanoantibiotic, the release kinetics of LEVO and the antimicrobial efficacy of each released dosage were evaluated. Besides, internalization studies of the MSNs functionalized with the G3 dendrimer were carried out, showing a high penetrability throughout Gram-negative bacterial membranes. This work evidences that the synergistic combination of polycationic dendrimers as bacterial membrane permeabilization agents with LEVO-loaded MSNs triggers an efficient antimicrobial effect on Gram-negative bacterial biofilm. These positive results open up very promising expectations for their potential application in new infection therapies.

description: In this work, in the context of modified gravity, a curved spacetime analogous to the "canonical acoustic black hole" is constructed. The source is a self-interacting scalar field which is non-minimally coupled to gravity through the Gauss-Bonnet invariant. The scalar-Gauss-Bonnet coupling function is characterized by three positive parameters: $σ$ with units of $(length)$, $μ$ with units of $(length)^{4}$, and a dimensionless parameter $s$, thus defining a three-parameter model for which the line element of canonical acoustic black hole is a solution. The spacetime is equipped with spherical and static symmetry and has a single horizon determined in Schwarzschild coordinates by the region $r=μ^{1/4}$. The solution admits a photon sphere at $r=(3μ)^{1/4}$, and it is shown that in the region $(3μ)^{1/4}\leq r

description: Since spin and charge are both carried by electrons (or holes) in a solid, it is natural to assume that charge and spin diffusion coefficients will be the same. Drift-diffusion models of spin transport typically assume so. Here, we show analytically that the two diffusion coefficients can be vastly different in quantum wires. Although we do not consider quantum wells or bulk systems, it is likely that the two coefficients will be different in those systems as well. Thus, it is important to distinguish between them in transport models, particularly those applied to quantum wire based devices

description: Focusing electromagnetic field to enhance the interaction with matter has been promoting researches and applications of nano electronics and photonics. Usually, the evanescent-wave coupling is adopted in various nano structures and materials to confine the electromagnetic field into a subwavelength space. Here, based on the direct coupling with confined electron oscillations in a nanowire, we demonstrate an extreme localization of microwave field down to 10$^{-6}λ$. A hybrid nanowire-bowtie antenna is further designed to focus the free-space microwave to this deep-subwavelength space. Detected by the nitrogen vacancy center in diamond, the field intensity and microwave-spin interaction strength are enhanced by 2.0$\times$10$^{8}$ and 1.4$\times$10$^{4}$ times, respectively. Such an extreme concentration of microwave field will further promote integrated quantum information processing, sensing and microwave photonics in a nanoscale system.

description: Video game level generation based on machine learning (ML), in particular, deep generative models, has attracted attention as a technique to automate level generation. However, applications of existing ML-based level generations are mostly limited to tile-based level representation. When ML techniques are applied to game domains with non-tile-based level representation, such as Angry Birds, where objects in a level are specified by real-valued parameters, ML often fails to generate playable levels. In this study, we develop a deep-generative-model-based level generation for the game domain of Angry Birds. To overcome these drawbacks, we propose a sequential encoding of a level and process it as text data, whereas existing approaches employ a tile-based encoding and process it as an image. Experiments show that the proposed level generator drastically improves the stability and diversity of generated levels compared with existing approaches. We apply latent variable evolution with the proposed generator to control the feature of a generated level computed through an AI agent's play, while keeping the level stable and natural.

description: We report the initial results of a large-scale optical-near infrared survey to extend the known young population of the entire Orion star-forming region down to the substellar domain. Using deep optical I-band photometry and data from the 2MASS survey, we selected candidates across ~14.8 deg^2 in the ~8 Myr old Ori OB1a subassociation and over ~6.7 deg^2 in the Ori OB1b subassociation (age ~3), with completeness down to 0.05Mo and 0.072Mo respectively. We obtained low resolution optical spectra for a subsample of 4 candidates in Ori OB1a and 26 in Ori OB1b; as a result we confirmed 3 new members in Ori OB1a, one of which is substellar, and 19 new members in Ori OB1b, out of which 7 are at the substellar limit and 5 are substellar. We looked into the presence of accretion signatures by measuring the strength of the Ha line in emission. Accordingly, we classified the new members as having Classical T-Tauri star (CTTS) or Weak Lined T Tauri star-like (WTTS) nature. We found that all the new members confirmed in Ori OB1a are WTTSs, while 39 +25/-22 % of the new members in Ori OB1b exhibit CTTS-like behavior, suggestive of ongoing accretion from a circum(sub)stellar disk. Additionally we found that none of the members confirmed in OB1a show near-IR color excess while 38 +26/-21 % of OB1b members show H-K color excess. These results are consistent with recent findings for low mass young stars in Orion OB1. The similarity in CTTS-like properties and near-IR excess across the substellar boundary gives support to the idea of a common formation mechanism for low mass stars and at least the most massive brown dwarfs. Finally, we remark the discovery of two new members classified as CTTSs, both exhibiting W(Ha) < -140 A, suggesting significant ongoing accretion.

Materials and Methods: Sixteen animals underwent insertion of either a SNCIPC or an uncoated silicone catheter. Half of the animals were sacrificed at day 7 and the others at day 30. Animal weight and assessment of well-being, pleural fluid and blood collection were performed at regular intervals. Pleurodesis was assessed at necropsy and histopathological examination of organs performed. Results: No mortality or significant clinical findings were observed throughout the experiment. SNCIPC treated animals had increased pleural fluid drainage overall (p Conclusions: SNCIPC are well tolerated and not associated with any significant signs of toxicity. Silver levels were elevated in local tissues, serum and liver but without evidence of pathological impact. Effective pleurodesis was present by day 7 and more established by day 30. Clinical studies to investigate the safety and efficacy of this device in patients with malignant pleural effusions appear warranted.
A one year follow-up of the differential effects of experiential and systemic interventions in resolving marital conflict
Creators: name: Rempel, Rosa
Publisher: name: University of British Columbia
Year: 2010

description: This study investigated the differential effects of two interventions in the treatment of marital discord one year following the termination of ten sessions of marital counselling on the dependent measures of conflict resolution (CRS), attainment of specified relationship goals (GAS), target complaint reduction (TC) and increased marital adjustment (DAS). The two treatments under investigation were an experiential intervention in which the goal is for partners to access and acknowledge, in both themselves and the other, previously unexpressed feelings underlying the reactive behaviour patterns and a systemic intervention in which the focus is on modifying patterns of communication. Twenty couples, ten from each treatment group, completed the standardized instruments as well as a qualitative follow-up questionnaire. The results of this study indicated that both treatment groups made significant gains at termination of active therapy on measures of goal attainment, marital adjustment, conflict resolution, and target complaints. The results also indicated that these gains were maintained over a one year period. Indeed, both treatments were effective in treating couples with problems of marital discord and have powerful components for changing the nature of relationships and maintaining those changes over a one year period.

description: Atomically thin vanadium diselenide (VSe2 ) is a two-dimensional transition metal dichalcogenide exhibiting attractive properties due to its metallic 1T-phase. With the recent development of methods to manufacture high-quality monolayer VSe 2 on van der Waals materials, the outstanding properties of VSe2 -based heterostructures have been widely studied for diverse applications. Dimensional reduction and interlayer coupling with a van der Waals substrate lead to its distinguishable characteristics from its bulk counterparts. However, only a few fundamental studies have investigated the interlayer coupling effects and hot electron transfer dynamics in VSe2 heterostructures. In this work, we reveal ultrafast and efficient interlayer hot electron transfer and interlayer coupling effects in VSe2 /graphene heterostructures. Femtosecond time-resolved reflectivity measurements showed that hot electrons in VSe 2 were transferred to graphene within a 100-fs timescale with high efficiency. Besides, coherent acoustic phonon dynamics indicated interlayer coupling in VSe2 /graphene heterostructures and efficient thermal energy transfer to three-dimensional substrates. Our results provide valuable insights into the intriguing properties of metallic transition metal dichalcogenide heterostructures and motivate designing optoelectronic and photonic devices with tailored properties.

description: Despite great progress in Pipunculidae (Insecta: Diptera) systematics during the past decades, the Mediterrane-an fauna of big-headed flies remains largely unknown. Here, we present new faunistic and taxonomic data for 98 named species from Cyprus, Egypt, France, Greece, Italy, Malta, Morocco, Portugal, Spain, Tunisia, and Turkey, based on our own collecting efforts and museum specimens. Besides 56 first national records, the paper includes the description of Cephalops(Semicephalops)  brachium  Kehlmaier    Withers  sp.  n.  from  France  and  Spain,  and  of  TomosvaryellaositoKehlmaier,  Gibbs    Withers  sp.  n.  and  Tomosvaryella  pugiunculus  Kehlmaier    Gibbs  sp.  n.  from  the  Balear  Islands  (Spain). Furthermore, two new synonymies are proposed: Tomosvaryella lyneborgi (Coe, 1969) = Tomosvaryella cilitar-sis (Strobl, 1910); and Tomosvaryella glabrum (Adams, 1905) = Tomosvaryella pilosiventris (Becker, 1900). Lectotypes are designated for Tomosvaryella pilosiventris (Becker, 1900) and Tomosvaryella vicina (Becker, 1900). The following species need to be deleted from the Spanish checklist due to misidentifications: Cephalops subultimus Collin, 1956, Eu-dorylas montium (Becker, 1897), and Tomosvaryella nigronitida Collin, 1958.
Revisiting the Fermi Golden Rule: Quantum Dynamical Phase Transition as a Paradigm Shift

description: Classical and quantum phase transitions involve observables which are non-analytic as functions of a controlled thermodynamical variable. As occurs with the self-consistent Fermi Golden Rule, one condition to obtain the discontinuous behavior is the proper evaluation of a classical or quantum thermodynamic limit. We show that in presence of an environment, the oscillatory dynamics of a quantum two-level system, in analogy with a classical damped oscillator, can undergo a quantum dynamical phase transition to a non-oscillatory phase. This is obtained from a self-consistent solution of the Generalized Landauer Buettiker Equations, a simplified integral form of the Keldysh formalism. I argue that working at each side of the transition implies standing under different paradigms in the Kuhn's sense of the word. In consequence, paradigms incommensurability obtains a sound mathematical justification as a consequence of the non-analyticity of the observables. A strong case is made upon the need to deepen the public's intuition and understanding on the abrupt transition from static to dynamical friction regimes.

MATERIAL EXAMINED
Four females collected from one location.
MEASUREMENTS
See Table 1.
DISTRIBUTION
Collected in March, 2010 from Ahar Village, Tehran Province, Iran, in the rhizosphere of grasses.
REMARKS
The examined specimens fit very well with the recent redescription of this species by Guerrero et al. (2008a), although some observed morphometric differences are considered as intraspecific variation. The Iranian population has a slightly longer pharyngeal expansion (140-162 vs 111-142 µ m) and shorter female tail (19-24 vs 22-37 µ m; c = 73-104 vs 53-83; cļ = 0.4-0.6 vs 0.6-0.8). Moreover, taking into account the tripartite nature of the uterus in this species, as illustrated by Guerrero et al. (2008a), the Iranian population has a less developed pars distalis than Iberian populations, although the pars dilatata oviductus is more developed than in the Iberian specimens and female tail lacks saccate bodies (vs some very small bodies observed).
One of the four females observed had two vulvae. Its morphometrics are: L = 1.89 mm, a = 23.9, b = 5.1, c = 82, cļ = 0.5, V 1 = 34.0, V 2 = 41.5, lip region diam. = 22 µ m, odontostyle length = 45 µ m, odontophore length = 53 µ m, neck length = 372 µ m, pharyngeal expansion length = 155 µ m, anal body diam. = 45 µ m and tail length = 23 µ m.
This is the first report of the species in Iran.

The effects of a re-entry program on locus of control and self-regard
Creators: name: Dextraze, Rhonda Dianne
Publisher: name: University of British Columbia
Year: 2010

description: In this study the effects of skills training are examined, and the moderating effects of two individual difference variables -- locus of control and self-esteem -- are investigated. The training program "Career Opportunities in Preparation for Employment", or C.O.P.E., which is three months in length, prepares single parent mothers on income assistance for retraining or re-entry into the work place. Thirty-nine participants were pre- and post-tested using Rotter's Locus of Control Scale and Shostrom's Personal Orientation Inventory which contains a "Self-Regard" subscale. The sample included two separate C.O.P.E. classes and two separate control groups, totalling thirty-nine subjects. Interviews were carried out before training to assess the goals of the program for the referral agent, the instructor and the participants, and at the end of training to determine whether participants had career plans, whether they felt successful and to what they attributed success and failure. Repeated measures analysis of variance was employed to test hypotheses regarding effects of training on locus of control and self-regard. It was found that locus of control improved at a statistically significant level (p < .05) for both treatment and control groups over the time period between the pre- and post-tests. There was no statistically significant difference found in improvement of locus of control between the treatment and control group over the same period. Pre-post changes in measured self-regard were significantly greater (p < .05) for the experimental group than for the control group. Additional tests were carried out on this variable. An ANOVA for the self-regard variable indicated that no significant differences existed between the two treatment groups tested or between the treatment groups' measured improvement over time. However, a simple main effects test established an initial difference between treatment and control group means at pre-test time with no difference at post-test time. Interviews of the women at both pre- and post-test times indicated improved clarity in future plans, verbalized personal success in line with self-esteem changes and attributions for perceived success and failures. Findings suggest that both self-selection and instructor screening may have affected the analysis and may affect the usefulness of the program for participants.

description: Abstract

 

This review analyses the challenges and opportunities of using commercially produced aquafeeds in Zambia for tilapia cultivation, considering population growth, income, and cultural preferences, while also highlighting potential advantages. High-quality aquafeed is essential for optimal growth, feed conversion efficiency, and fish health, promoting increased utilization in the country. The establishment of modern facilities by Skretting, Aller Aqua, and Novatek is having a positive impact on Zambia's fish feed production. These companies are dedicated to achieving a sustainable balance between commercial expansion and smallholder development, while also fostering growth in the aquaculture value chain. Challenges such as substandard feed production, rising costs, limited access to affordable raw materials, and insufficient funding are being faced by the industry. These obstacles have the potential to significantly influence the industry's growth and economic contribution.

Social relationships of lesbian and heterosexual feminist women
Creators: name: Henderson, Patricia
Publisher: name: University of British Columbia
Year: 2010

description: This study explored the relationship between sexual preference and friendship amongst lesbian and heterosexual feminist women. Seventy respondents, 35 heterosexual and 35 lesbian feminist women between the ages of 20 and 40 participated. Respondents were initially screened by use of the Feminist Identification Rating Scale, and included in the study if they rated themselves at 7 or higher on a scale of 1 to 10. They were then administered the Personal Data Sheet (Lustig, 1982), The Close Friendship Scale (Frum, 1979), and the Social Provisions Scale, 1982). This was an ex post facto comparison study with one independent variable (sexual preference) and twelve dependent variables which were the twelve subscales on the instruments. The data was analyzed by means of analysis of variance and chi-square techniques. The main conclusions of this study were: 1. There is no relationship between the qualities of close friendship and sexual preference. 2. There is no relationship between the provisions of close friendship and sexual preference. 3. There is evidence which suggests that women tend to experience their close friendships similarly, regardless of sexual preference. The findings of the study support an approach to understanding the friendships of lesbian women which focuses on the similarities between lesbian and heterosexual women. The study thus contributes to the process of understanding the lesbian experience.
