description: In the search of QCD phase boundary and critical point, higher-order cumulants of conserved quantities are proposed as promising observables and have been studied extensively both experimentally and theoretically. In this paper we present cumulant ratios up to $6^{th}$-order of net-proton number distributions in Au+Au collisions at $\sqrt{\mathrm{s_{NN}}}$ = 7.7 - 200 GeV from STAR Beam Energy Scan program phase I and $\sqrt{\mathrm{s}}$ = 200 GeV $p+p$ collisions. The results are compared with various models and Lattice QCD calculations.

The work environment and burnout among family and child care workers
Creators: name: Sutton, James Henry
Publisher: name: University of British Columbia
Year: 2010

description: This thesis explores the relationship between work environment and burnout by examining the question: Do workers experiencing burnout see their work environment more negatively than co-workers who are not burned-out? The goal is to explore the potential usefulness of measures of work environment and burnout to guide efforts at burnout intervention and prevention. Thirty-nine family and childcare workers from five sites in the Vancouver area responded to a survey to test hypotheses addressing this question. The work environment and burnout were found to be highly interactive with the work environment variables of supervisor support and clarity identified as key factors in burnout. The Maslach Burnout Inventory and Moos (1981) Work Environment Scale were found to be useful instruments for intervention and future research.

It is one of the most abundant and widely distributed species in the region (Fig. 8). Oygur and Wolfe (1991) recorded the species from streams and lakes while Morrissette (1979) reported it from stagnant water. It is found in both lotic (41%) and lentic (59%) habitats (Oygur and Wolfe 1991).

description: Let k be a positive integer and let G_k denote the set of non-commutative k-variable distributions μsuch that μ(X_1) = ... = μ(X_k) = 1. G_k is a group under the operation of free multiplicative convolution. We identify G_k as the group of characters of a certain Hopf algebra Y_k. Then, by using the log map from characters to infinitesimal characters of Y_k, we introduce a transform LS_μ for distributions μin G_k. The main property of the LS-transform is that it linearizes commuting products in G_k. For μin G_k, the transform LS_μ is a power series in k non-commuting indeterminates; its coefficients can be computed from the coefficients of the R-transform of μby using summations over chains in the lattices NC(n) of non-crossing partitions. In the particular case k=1 one has that Y_1 is naturally isomorphic to the Hopf algebra Sym of symmetric functions, and that the LS-transform is very closely related to the logarithm of the S-transform of Voiculescu, by the formula LS(z) = - z log S(z). In this case the group G_1 can be identified as the group of characters of Sym, in such a way that the S-transform, its reciprocal 1/S and its logarithm log S relate in a natural sense to the sequences of complete, elementary and respectively power sum symmetric functions.

description: We present a supersymmetric recursion relation for tree-level scattering amplitudes in N=4 super Yang-Mills. Using this recursion relation, we prove that the tree-level S-matrix of the maximally supersymmetric theory is covariant under dual superconformal transformations. We further analyse the consequences that the transformation properties of the trees under this symmetry have on those of the loops. In particular, we show that the coefficients of the expansion of generic one-loop amplitudes in a basis of pseudo-conformally invariant scalar box functions transform covariantly under dual superconformal symmetry, and in exactly the same way as the corresponding tree-level amplitudes.

description: A self-control mechanism that stabilizes the size of Rhodamine B-doped water microdroplets standing on a superhydrophobic surface is demonstrated. The mechanism relies on the interplay between the condensation rate that was kept constant and evaporation rate induced by laser excitation which critically depends on the size of the microdroplets. The radii of individual water microdroplets (>5 um) stayed within a few nanometers during long time periods (up to 455 seconds). By blocking the laser excitation for 500 msec, the stable volume of individual microdroplets was shown to change stepwise.

description: In this paper, we present a novel universal coupled theory for metamaterial Bound states in the continuum (BIC) or quasi-Bound states in the continuum (quasi-BIC) which provides ultra-high Q resonance for metamaterial devices. Our theory analytically calculates the coupling of two bright modes with phase. Our method has much more accuracy for ultra-strong coupling comparing with the previous theory (the coupling of one bright mode and one dark mode). Therefore, our theory is much more suitable for BIC or quasi-BIC and we can accurately predict the transmission spectrum of metamaterial BIC or quasi-BIC for the first time.

description: Here we report the superconductivity in the LaFeAsO1-xFx system prepared by high pressure synthesis. The highest onset superconducting transition temperature (Tc) in this La-based system is 41.0 K with the nominal composition of LaFeAsO1-xFx (x = 0.6), which is higher than that reported previously by ambient pressure synthesis. The increase of Tc can be attributed to the further shrinkage of crystal lattice that causes the stronger chemical pressure on the Fe-As plane, which is induced by the increased F-doping level under high pressure synthesis.

description: We report the discovery of large amounts of previously undetected cold neutral atomic hydrogen (\HI) around the core triplet galaxies in the nearby NGC~7232 galaxy group with MeerKAT. With a physical resolution of $\sim$1 kpc, we detect a complex web of low surface brightness \HI\ emission down to a 4$σ$ column density level of $\sim$1 $\times$ 10$^{19}$ cm$^{-2}$ (over 44 \kms ). The newly discovered H\,{\sc i} streams extend over $\sim$20 arcmin corresponding to 140~kpc in projection. This is $\sim$3 times the \HI\ extent of the galaxy triplet (52 kpc). The \HI\ debris has an \HI\ mass of $\sim$6.6 $\times 10^9$~M$_{\odot}$, more than 50\% of the total \HI\ mass of the triplet. Within the galaxy triplet, NGC~7233 and NGC~7232 have lost a significant amount of \HI\ while NGC~7232B appears to have an excess of \HI. The \HI\ deficiency in NGC~7232 and NGC~7233 indicates that galaxy-galaxy interaction in the group concentrates on this galaxy pair while the other disc galaxies have visited them over time. In comparison to the AMIGA sample of isolated galaxies we find that with regards to its total \HI\ mass the NGC~7232/3 galaxy triplet is not \HI\ deficient. Despite the many interactions associated to the triplet galaxies, no \HI\ seems to have been lost from the group (yet).

description: Sakuma and Imai [Phys. Rev. Lett. 107, 198101 (2011)] established a temperature-controlled cyclic process for a model system of self-reproducing vesicles without feeding. The vesicle generates a smaller inclusion vesicle called "daughter vesicle" inside the original vesicle (we call this "mother vesicle") and then the daughter vesicle is expelled through a small pore on the mother vesicle. This self-reproducing process is called birthing. In the present study we present theoretical model on the birthing process of a single, rigid daughter vesicle through a pore. By using a simple geometric picture, we derive the free energy constituting the material properties of the bending, stretching and line tension moduli of the mother vesicle, as a function of the distance between the centers of the daughter and mother vesicles, and the size of the daughter vesicle. We see clearly the disappearance of the energy barrier by selecting appropriate moduli. The dynamics of the system is studied by employing the Onsager principle. The results indicate that translocation time decreases as the friction parameter decreases, or the initial size of the daughter vesicle decreases.

In Nova Scotia it has only been found on Cape Breton Island (Fig. 2). Although Roughley (1991) reported it from Prince Edward Island, Majka (2008) removed it from the province’s faunal list since there are no voucher specimens or published records. Morrissette (1979) reported the species from ponds and lakes invaded by aquatic plants. Oygur and Wolfe (1991) reported 80% of specimens from lentic habitats.

Evaluation of the arthritis men's group

Publisher: name: University of British Columbia
Year: 2010

description: Approximately 18 months ago, an Arthritis Men's Group was started by the Social Work Department at the Vancouver Arthritis Centre. Having identified the need for such a group, interim objectives were proposed for the group which was still in the pilot stage of its development. The purpose of the study was to conduct a formative evaluation of the Men's Group to take a closer look at what was happening in the sessions, to examine the feasibility of the objectives and whether these objectives were being achieved. This information would be used by the planners to improve and/or modify the program. The underlying conceptual approach to the study was 'naturalistic'. In the context of this framework, several data collection methods were used including: interviews, quantitative measures, monitoring and narrative descriptions of group sessions. The findings suggested that interim objectives were being met in the sessions which focussed specifically on psycho-social issues. In addition, other sessions were serving an important 'informational' function which was recognized and valued by group members. Interviews with core-group members did indicate the perceived acceptance and usefulness of open discussions on psycho-social issues. However, over the short duration of the monitoring period no significant changes were found on the measures pre to post so that the positive or negative effects of the achievement of higher levels of emotional openness is not known. The study did provide a good preliminary data base on the nature of the group process and the heterogeneity of the membership. Useful information was gathered both on the kind of group process which may facilitate the achievement of the specific program objectives as well as the informational function of the group. Overall, group members seemed satisfied with group process and content and wanted to see the group continue.

description: Addressing today’s complex, global research challenges, such as the threats posed by climate change and other environmental hazards associated with breaching our planetary health boundaries, has never been as urgent. Much of the data and information to tackle such problems is at our fingertips, the question is how to acquire, assemble and analyse diverse and complex information as expeditiously as possible to arrive at new understanding and recommendations for action or policies. Such cross-domain synthesis involves achieving four key components: (i) successful collaboration between experts and stakeholders across disciplinary, skillset, organisational and national boundaries, (ii) the availability of relevant, trusted, good quality data and code fit for use, (iii) access to the best infrastructure and tools available, wherever they may be, and (iv) openly-available results for critical review and future use. The presentation draws on examples from around the world to illustrate important key elements that can support effective collaboration, both at an individual and a team level. The means by which the researcher might identify good quality data and code for use is covered together with examples of the use of infrastructures of various sorts that may assist the team achieve their goal. The talk is given against the background of open science (UNESCO, 2021) and how the work of an individual and a project can be best presented within the academic community.

description: We report the discovery of a giant Lya emitter (LAE) with a Spitzer/IRAC counterpart near the reionization epoch at z=6.595. The giant LAE is found from the extensive 1 deg^2 Subaru narrow-band survey for z=6.6 LAEs in the Subaru/XMM-Newton Deep Survey (SXDS) field, and subsequently identified by deep spectroscopy of Keck/DEIMOS and Magellan/IMACS. Among our 207 LAE candidates, this LAE is not only the brightest narrow-band object with L(Lya) = 3.9+/-0.2 x 10^43 erg/s in our survey volume of 10^6 Mpc^3, but also a spatially extended Lya nebula with the largest isophotal area whose major axis is at least ~3''. This object is more likely to be a large Lya nebula with a size of >~17 kpc than to be a strongly-lensed galaxy by a foreground object. Our Keck spectrum with medium-high spectral and spatial resolutions suggests that the velocity width is v(FWHM)=251+/-21 km/s, and that the line-center velocity changes by ~60 km/s in a 10-kpc range. The stellar mass and star-formation rate are estimated to be 0.9-5.0 x 10^10 Mo and >34 Mo/yr, respectively, from the combination of deep optical to infrared images of Subaru, UKIDSS-Ultra Deep Survey, and Spitzer/IRAC. Although the nature of this object is not yet clearly understood, this could be an important object for studying cooling clouds accreting onto a massive halo, or forming-massive galaxies with significant outflows contributing to cosmic reionization and metal enrichment of inter-galactic medium.

description: Technological advances in instrumentation have led to an exponential increase in exoplanet detection and scrutiny of stellar features such as spots and faculae. While the spots and faculae enable us to understand the stellar dynamics, exoplanets provide us with a glimpse into stellar evolution. While the ubiquity of noise (e.g., telluric, instrumental, or photonic) is unavoidable, combining this with increased spectrographic resolution compounds technological challenges. To account for these noise sources and resolution issues, we use a temporal multifractal framework to study data from the SOAP 2.0 tool, which simulates a stellar spectrum in the presence of a spot, a facula or a planet. Given these controlled simulations, we vary the resolution as well as the signal-to-noise (S/N) ratio to obtain a lower limit on the resolution and S/N required to robustly detect features. We show that a spot and a facula with a 1% coverage of the stellar disk can be robustly detected for a S/N (per pixel) of 35 and 60 respectively, for any spectral resolution above 20,000, while a planet with a radial velocity (RV) of 10 m/s can be detected for a S/N (per pixel) of 600. Rather than viewing noise as an impediment, our approach uses noise as a source of information.

description: In this work linear stability analysis of a four-fluid optically thin plasma consisting of electrons, ions, neutral atoms, and charged dust particles is performed with respect to the radiation-condensation (RC) instability. The energy budget of the plasma involves the input from heating through photo-electron emission by dust particles under external ultraviolet radiation as well as radiative losses in inelastic electron-neutral, electron-ion, neutral-neutral collisions. It is shown that negatively charged particles stimulate the RC instability in the sense that the conditions for the instability to hold are wider than similar conditions in a single-fluid description.

description: Advances in computing have resulted in an emerging need for multi-factor authentication using an amalgamation of cryptographic and physical keys. This letter presents a novel authentication approach using a combination of signal and antenna activation sequences, and most importantly, perturbed antenna array geometries. Possible degrees of freedom in perturbing antenna array geometries affected physical properties and their detection are presented. Channel estimation for the plurality of validly authorized arrays is discussed. Accuracy is investigated as a function of signal-to-noise ratio (SNR) and number of authorized arrays. It is observed that the proposed authentication scheme can provide 1% false authentication rate at 10 dB SNR, while it is achieving less than 1% missed authentication rates.

Pulsar slow glitches in a solid quark star model

description: A series of five unusual slow glitches of the radio pulsar B1822-09 (PSR J1825-0935) were observed over the 1995-2005 interval. This phenomenon is understood in a solid quark star model, where the reasonable parameters for slow glitches are presented in the paper. It is proposed that, because of increasing shear stress as a pulsar spins down, a slow glitch may occur, beginning with a collapse of a superficial layer of the quark star. This layer of material turns equivalently to viscous fluid at first, the viscosity of which helps deplete the energy released from both the accumulated elastic energy and the gravitation potential. This performs then a process of slow glitch. Numerical calculations show that the observed slow glitches could be reproduced if the effective coefficient of viscosity is ~10^2 cm^{2}/s and the initial velocity of the superficial layer is order of 10^{-10} cm/s in the coordinate rotating frame of the star.

description: We show that seesaw models based on flavor symmetries (such as A_4 and Z_7 X Z_3) which produce exact tribimaximal neutrino mixing, also imply a vanishing leptogenesis asymmetry. We show that higher order symmetry breaking corrections in these models can give a non-zero leptogenesis asymmetry and generically also give deviations from tribimaximal mixing and a non-zero theta13 >~ 10^(-2)

Polling public opinions : a pilot study in marketing mental health
Creators: name: Toh, Jo-Anne
Publisher: name: University of British Columbia
Year: 2010

description: This paper provides preliminary information on consumer opinions and perceptions on various mental health issues. Recognizing that citizen in-put is an essential marketing tool for responsive and accountable program planning, the Canadian Mental Health Association - B.C. Division, is in the process of acquiring consumer data as part of its information bank. This pilot study has provided a 'dry run' of what is expected for future research projects. Through telephone interviews with 46 Vancouver City telephone subscribers and mail-out questionnaires to 46 community service: personnel, the Canadian Mental Health Association was able to acquire some relevant information to aid in its decision-making process for planning mental health educational programs. The majority of survey respondents, for example, feel that information on coping with stress is the most important to them while information on the more serious, mental disorders, such as schizophrenia, is least important. This has important implications for program planning if the organization is to enlist public support and market its services to a broader clientele. Focusing on promoting mental health and functional competence versus mental illness focused is recommended if the Canadian Mental Health Association hopes to attract normal population groups as its consumers. Furthermore, learning through friendship and familial support is the most desirable, and helping professionals should not place too much emphasis on pamphlets alone as an educational tool. Other implications arising from the consumer data are discussed in this paper. For the most part, the consumer data has served to verify assumptions about what decision-makers already know ... but the research process is able to ground such assumptions into fact ... and this helps to further legitimize and speed up action. This pilot study serves as an initial starting point for the organization in its attempt to incorporate consumer research as part of its overall planning process.

description: The long-standing goal of discriminating tree species at the crown-level from high spatial resolution imagery remains challenging. The aim of this study is to evaluate whether combining (a) high spatial resolution multi-temporal images from different phenological periods (spring, summer and autumn), and (b) leaf-on LiDAR height and intensity data can enhance the ability to discriminate the species of individual tree crowns of red oak (Quercus rubra), sugar maple (Acer saccharum), tulip poplar (Liriodendron tulipifera), and black cherry (Prunus serotina) in the Fernow Experimental Forest, West Virginia, USA. We used RandomForest models to measure a loss of classification accuracy caused by iteratively removing from the classification one or more groups from six groups of variables: spectral reflectance from all multispectral bands in the (1) spring, (2) summer, and (3) autumn images, (4) vegetation indices derived from the three multispectral datasets, (5) canopy height and intensity from the LiDAR imagery, and (6) texture related variables from the panchromatic and LiDAR datasets. We also used ANOVA and decision tree analyses to elucidate how the multispectral and LiDAR datasets combine to help discriminate tree species based on their unique phenological, spectral, textural, and crown architectural traits. From these results, we conclude that combing high spatial resolution multi-temporal satellite data with LiDAR datasets can enhance the ability to discriminate tree species at the crown level.

Visualizing curved spacetime

Publisher: name: arXiv
Year: 2007
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: I present a way to visualize the concept of curved spacetime. The result is a curved surface with local coordinate systems (Minkowski Systems) living on it, giving the local directions of space and time. Relative to these systems, special relativity holds. The method can be used to visualize gravitational time dilation, the horizon of black holes, and cosmological models. The idea underlying the illustrations is first to specify a field of timelike four-velocities. Then, at every point, one performs a coordinate transformation to a local Minkowski system comoving with the given four-velocity. In the local system, the sign of the spatial part of the metric is flipped to create a new metric of Euclidean signature. The new positive definite metric, called the absolute metric, can be covariantly related to the original Lorentzian metric. For the special case of a 2-dimensional original metric, the absolute metric may be embedded in 3-dimensional Euclidean space as a curved surface.

A Higher-Order Topological Insulator Phase in a Modulated Haldane Model

description: We explore topological properties of a modulated Haldane model (MHM) in which the strength of the nearest-neighbor and next-nearest-neighbor terms is made unequal and the three-fold rotational symmetry $\mathcal{C}_3$ is broken by introducing a trimerization term ($|t_{1w(2w)}|< t_{1s(2s)}$) in the Hamiltonian. Using the parameter $η={t_{1w}}/{t_{1s}}= t_{2w}/t_{2s}$, we show that the MHM supports a transition from the quantum anomalous Hall insulator (QAHI) to a HOTI phase at $η=\pm 0.5$. The MHM also hosts a zero-energy corner mode on a nano-disk that can transition to a trivial insulator without gap-closing when the inversion symmetry is broken. The gap-closing critical states are found to be magnetic semimetals with a single Dirac node which, unlike the classic Haldane model, can move along the high-symmetry lines in the Brillouin zone. MHM offers a rich tapestry of HOTI and other topological and non-topological phases.
