An evaluation of an experimental science enrichment program : "Light and illusion", Vancouver School Board, Arts and Sciences Centre, Vancouver, B.C. September 1980-June 1981
Creators: name: Letcher, Marshall
Publisher: name: University of British Columbia
Year: 2010

description: This study evaluated an experimental program in informal learning, “Light and Illusion,” developed by the Vancouver School Board in cooperation with the Arts and Sciences Centre of Vancouver. A mail questionnaire was developed based upon a review of the literature on informal learning . The questionnaire was distributed to the Vancouver School Board teachers who visited the workshop with their students. The study was conducted over a three month period; 94 of the 150 questionnaires sent out were returned (69% return ) . The questionnaire sought to determine which teachers (grade level and subject area) used the workshop, how teachers used the workshop, what teachers liked and disliked about the workshop, and what suggestions they had for future workshops. The results were reported as percentage responses to the questionnaire items. In addition , a series of observations and recommendations were made. In particular the study showed that 90% of the attending teachers were highly satisfied with the workshop as a learning experience for their students. They commented favorably on the quality of the exhibits , freedom of choice, and the noticeable increase in student interest in science. Elementary teachers rated the workshop more highly than did secondary teachers, although both indicated they benefited by seeing their students work in a novel environment. Teachers thought that further informal learning workshops should be offered to students through the cooperation of the Vancouver School Board and the Arts and Sciences Centre.

description: After the publication of [J. Algebra 638 (2024) 625-669], we noticed a serious mistake in the treatment of the partition algebra. In particular, we assumed in the proof of Lemma 4.9 that the trivial P_n-module is indexed by the empty set but it is actually indexed by the partition (n). In this erratum, we fix this mistake and give a complete proof of Theorem C.

description: In general, most of communication satellites were designed to be operated in geostationary orbit. And many of them were designed in prolate dual-spin configuration. As a prolate dual-spin vehicle, they have to be stabilized against their internal energy dissipation effect. Several countries that located in southern hemisphere, has shown interest to use communication satellite. Because of those countries southern latitude, an idea emerged to incline the communication satellite (due to its prolate dualspin configuration) in elliptical orbit. This work is focused on designing Attitude Stability System for prolate dual-spin satellite in the effect of perturbed field of gravity due to the inclination of its elliptical orbit. DANDE (De-spin Active Nutation Damping Electronics) provides primary stabilization method for the satellite in its orbit. Classical Control Approach is used for the iteration of DANDE parameters. The control performance is evaluated based on time response analysis.

description: In this paper, Bayesian based aggregation of decision trees in an ensemble (decision forest) is investigated. The focus is laid on multi-class classification with number of samples significantly skewed toward one of the classes. The algorithm leverages out-of-bag datasets to estimate prediction errors of individual trees, which are then used in accordance with the Bayes rule to refine the decision of the ensemble. The algorithm takes prevalence of individual classes into account and does not require setting of any additional parameters related to class weights or decision-score thresholds. Evaluation is based on publicly available datasets as well as on an proprietary dataset comprising network traffic telemetry from hundreds of enterprise networks with over a million of users overall. The aim is to increase the detection capabilities of an operating malware detection system. While we were able to keep precision of the system higher than 94\%, that is only 6 out of 100 detections shown to the network administrator are false alarms, we were able to achieve increase of approximately 7\% in the number of detections. The algorithm effectively handles large amounts of data, and can be used in conjunction with most of the state-of-the-art algorithms used to train decision forests.

description: The nonlinear propagation of 3D wave-packets in a 1D Bragg-induced band-gap system, shows that tranverse effects (free space diffraction) affect the interplay of periodicity and nonlinearity, leading to the spontaneous formation of fast and slow conical localized waves. Such excitation corresponds to enhanced nonlinear transmission (tunneling) in the gap, with peculiar features which differ on the two edges of the band-gap, as dictated by the full dispersion relationship of the localized waves.

Glueball matrix elements: a lattice calculation and applications

Subjects: subject: High Energy Physics - Lattice (hep-lat)

description: We compute the matrix elements of the energy-momentum tensor between glueball states and the vacuum in SU(3) lattice gauge theory and extrapolate them to the continuum. These matrix elements may play an important phenomenological role in identifying glue-rich mesons. Based on a relation derived long ago by the ITEP group for J/psi radiative decays, the scalar matrix element leads to a branching ratio for the glueball that is at least three times larger than the experimentally observed branching ratio for the f_0 mesons above 1GeV. This suggests that the glueball component must be diluted quite strongly among the known scalar mesons. Finally we review the current best continuum determination of the scalar and tensor glueball masses, the deconfining temperature, the string tension and the Lambda parameter, all in units of the Sommer reference scale, using calculations based on the Wilson action.

description: During the past five years the low temperature heat capacity of simple semiconductors and insulators has received renewed attention. Of particular interest has been its dependence on isotopic masses and the effect of spin- orbit coupling in ab initio calculations. Here we concentrate on the lead chalcogenides PbS, PbSe and PbTe. These materials, with rock salt structure, have different natural isotopes for both cations and anions, a fact that allows a systematic experimental and theoretical study of isotopic effects e.g. on the specific heat. Also, the large spin-orbit splitting of the 6p electrons of Pb and the 5p of Te allows, using a computer code which includes spin-orbit interaction, an investigation of the effect of this interaction on the phonon dispersion relations and the temperature dependence of the specific heat and on the lattice parameter. It is shown that agreement between measurements and calculations significantly improves when spin-orbit interaction is included.

description: Gaps imaged in protoplanetary discs are suspected to be opened by planets. We compute the present-day mass accretion rates $\dot{M}_{\rm p}$ of seven hypothesized gap-embedded planets, plus the two confirmed planets in the PDS 70 disc. The accretion rates are based on disc gas surface densities $Σ_{\rm gas}$ from C$^{18}$O observations, and planet masses $M_{\rm p}$ from simulations fitted to observed gaps. Assuming accretion is Bondi-like, we find in eight out of nine cases that $\dot{M}_{\rm p}$ is consistent with the time-averaged value given by the current planet mass and system age, $M_{\rm p}/t_{\rm age}$. As system ages are comparable to circumstellar disc lifetimes, these gap-opening planets may be undergoing their last mass doublings, reaching final masses of $M_{\rm p} \sim 10-10^2 \, M_\oplus$ for the non-PDS 70 planets, and $M_{\rm p} \sim 1-10 \, M_{\rm J}$ for the PDS 70 planets. For another fifteen gaps without C$^{18}$O data, we predict $Σ_{\rm gas}$ by assuming their planets are accreting at their time-averaged $\dot{M}_{\rm p}$. Bondi accretion rates for PDS 70b and c are orders of magnitude higher than accretion rates implied by measured U-band and H$α$ fluxes, suggesting most of the accretion shock luminosity emerges in as yet unobserved wavebands, or that the planets are surrounded by dusty, highly extincting, quasi-spherical circumplanetary envelopes. Thermal emission from such envelopes or from circumplanetary discs, on Hill sphere scales, peaks at wavelengths in the mid-to-far-infrared and can reproduce observed mm-wave excesses.

description: The merger of two neutron stars or of a neutron star and a black hole often result in the ejection of a few percents of a solar mass of matter expanding at high speed in space. Being matter coming from the violent disruption of a neutron star, these ejecta are initially very dense, hot and extremely rich in neutrons. The few available protons form heavy nuclei ("seeds") that absorb the more abundant free neutrons, increasing their size. The neutron density is so high that a substantial number of neutron captures occur before the resulting unstable nuclei can decay toward more stable configurations, converting neutrons into protons. Depending mostly on the initial neutron richness, this mechanism leads to the formation of up to half of the heavy elements that we observe in nature and it is called rapid neutron capture process ("$r$-process"). The prediction of the precise composition of the ejecta requires a detailed knowledge of the properties of very exotic nuclei, that have never been produced in a laboratory. Despite having long been a speculative scenario, nowadays several observational evidences point to compact binary mergers as one of the major sites where heavy elements are formed in the Universe. The most striking one was the detection of a kilonova following the merger of a neutron star binary: the light emitted by this astronomical transient is indeed powered by the radioactive decay of freshly synthesized neutron-rich nuclei and testifies the actual nature of compact binary mergers as cosmic forges.

description: This review presents a comprehensive overview of Myrzakulov gravity, highlighting key developments and significant results shaping the theory. It examines the foundational principles, field equations, and the role of non-metricity and torsion in gravitational interactions. The theory's implications extend to cosmology, astrophysics, and strong gravitational fields, offering alternatives to dark matter and dark energy. A focus is placed on the modified Einstein-Hilbert action, its impact on cosmic expansion, and astrophysical applications such as black holes and gravitational waves. Observational constraints from cosmology and gravitational wave tests are discussed to refine the model. By situating Myrzakulov gravity within the broader context of modified gravity, this review explores its potential to reshape fundamental physics.

description: Using a large sample of optical spectra of late-type dwarfs, we identify a subset of late-M through L field dwarfs that, because of the presence of low-gravity features in their spectra, are believed to be unusually young. From a combined sample of 303 field L dwarfs, we find observationally that 7.6+/-1.6% are younger than 100 Myr. This percentage is in agreement with theoretical predictions once observing biases are taken into account. We find that these young L dwarfs tend to fall in the southern hemisphere (Dec < 0 deg) and may be previously unrecognized, low-mass members of nearby, young associations like Tucana-Horologium, TW Hydrae, beta Pictoris, and AB Doradus. We use a homogeneously observed sample of roughly one hundred and fifty 6300-10000 Angstrom spectra of L and T dwarfs taken with the Low-Resolution Imaging Spectrometer at the W. M. Keck Observatory to examine the strength of the 6708-A Li I line as a function of spectral type and further corroborate the trends noted by Kirkpatrick et al. (2000). We use our low-gravity spectra to investigate the strength of the Li I line as a function of age. The data weakly suggest that for early- to mid-L dwarfs the line strength reaches a maximum for a few 100 Myr, whereas for much older (few Gyr) and much younger (<100 Myr) L dwarfs the line is weaker or undetectable. We show that a weakening of lithium at lower gravities is predicted by model atmosphere calculations, an effect partially corroborated by existing observational data. Larger samples containing L dwarfs of well determined ages are needed to further test this empirically. If verified, this result would reinforce the caveat first cited in Kirkpatrick et al. (2006) that the lithium test should be used with caution when attempting to confirm the substellar nature of the youngest brown dwarfs.

description: Pavement macrotexture contributes greatly to road surfacefriction, which in turn plays a vital role in reducingroad accidents. Conventional methods for macrotexturemeasurement are either expensive, time-consuming, or ofpoor repeatability. Based on multi-view smartphone imagescollected in situ, this paper develops and evaluates an affordable and convenient alternative approach for pavement macrotexture measurement. Photogrammetric computer vision techniques are first applied to create high resolution point clouds of the pavement. Analytics are then developed to determine the macrotexture metric: mean profile depth by using the image-based point clouds. Experiments are carried out with 790 images over 25 spots on three state routes and six spots at an Indiana Department of Transportation test site. We demonstrate multi-view smartphone images can yield results comparable to the ones from the conventional laser texture scanner. It is expected that the developed approach can be adopted for large scale operational uses.

description: The phi4 scalar field theory in three dimensions, prototype for the study of phase transitions, is investigated by means of the hierarchical reference theory (HRT) in its smooth cutoff formulation. The critical behavior is described by scaling laws and critical exponents which compare favorably with the known values of the Ising universality class. The inverse susceptibility vanishes identically inside the coexistence curve, providing a first principle implementation of the Maxwell construction, and shows the expected discontinuity across the phase boundary, at variance with the usual sharp cutoff implementation of HRT. The correct description of first and second order phase transitions within a microscopic, nonperturbative approach is thus achieved in the smooth cutoff HRT.

The biology of the host-specific epiphytic red alga Ceramium codicola and some other epiphytes of Codium spp. in British Columbia
Creators: name: Lewis, Raymond Jerald
Publisher: name: University of British Columbia
Year: 2010

description: Field and culture studies have been carried out with the epiphytic red alga, Ceramium codicola J. Agardh, with the objective of determining what factors in its biology cause it to be limited to growth on one host plant, Codium fragile (Suringar) Hariot. A survey of epiphytes of C. fragile and C. setcheIIii confirm the absence of C. codicoIa on C. setcheIIii and shows that C. codicola is the most abundant epiphyte on C. fragiIe. More species of epiphytes were present in wave sheltered areas. C. codicoIa was not present in samples from the Strait of Georgia. In culture, C. codicoIa grew to reproductive maturity apart from C. fragiIe from spores, but the life history was not completed. The presence of living or extracted C. fragiIe or C. setcheIIii did not promote germination, growth or reproduction of C. codicola, and typically inhibited it. C. codicoIa did not grow well at temperatures above 15°C in culture; C. fragiIe, Ceramium pacificum and C. gardner i grew weII at 10-18°C. Rhizoids of C. codicola have bulbous tips, which appears to be genetically determined. Substratum can affect later development of these rhizoids, which may obscure the bulbous nature of the rhizoid tips. C. codicoIa is unable to produce digitate holdfasts on its rhizoid tips, as was observed in other Ceramium spp. , and may only be able to attach by entangling its rhizoids in loosely constructed substrata such as Codium spp. C. setcheIIii is not suitable because it is too compact, and penetration of rhizoids is inhibited. Field studies show that C. codicoIa is reproductive throughout the year, although reduced in the winter. Thallus length was also reduced in the winter. In addition, thalIi were longer in wave sheltered sites, and longer in the upper regions of their intertidal distribution. Male and female gametophytes and tetrasporophytes of C. codicola exhibit a hetermorphism in branching pattern. Gametophytes differ from tetrasporophytes by having more primary branches and larger angles of branching. Females differ from males by having a higher degree of proliferous branching, resulting in a higher number of primary branches and a higher branching ratio. Branching pattern in females may be the result of continued growth of involucral ramuli, and it may optimize reproductive potential.

Subjects: search and retrieval services, recommender service, question answering, semantic similarity

description: The Lynx project aims at facilitating cross-border compliance for European enterprises. This requires the gathering of relevant regulations, case laws, best practices and standards, and their provision through accessible means, which enable end users (in the form of law firms, in-house lawyers, SMEs and the general public) to find answers to their regulatory related needs with ease. In order to provide such accessible means, the Lynx partners had brought together their technical expertise in the fields of Information Extraction, Semantic Web, Knowledge Management, and Document Management, to create an integrated solution. An essential part of the solution provided by Lynx is the automatic analysis of documents in order to facilitate their discovery and retrieval by the end user. These analyses have three primary objectives: To extract information contained within the documents that is relevant to user queries. To put documents in context, in terms of relations they hold to other documents. To make documents accessible in different languages. In order to realize these objectives, Work Package 3 serves to develop a series of services that extract various types of information from the documents, and store the information in a well-organized, standards-compliant knowledge graph, which we call the Legal Knowledge Graph (LKG). This LKG will contain not only information about these documents, but also information extracted from them, as well as general knowledge from the compliance domain, in the form of controlled vocabularies. The services that are reported in this deliverable are Information Retrieval and Recommender Services. Search service provides a lookup through all the corpora and retrieves related documents corresponding to a given query. Question Answering takes in a natural language question and returns the most promising answer. Semantic Similarity service adds extra knowledge that is useful for the applications mentioned above. Being an intermediate report, not all of the services have been fully implemented. However, large amounts of work have been done in the standardization of the service architecture, deployment procedure and data interchange format. Furthermore, demonstration implementations are available for most of the services listed here, which are being used to test interoperability among them. Finally, some of these services are the result of ongoing research, and thus their initial version is already an innovation success.

description: First-principles electronic band structure investigations of five compounds of the CaO-Al2O3 family, 3CaO.Al2O3, 12CaO.7Al2O3, CaO.Al2O3, CaO.2Al2O3 and CaO.6Al2O3, as well as CaO and alpha-, theta- and kappa-Al2O3 are performed. We find that the conduction band in the complex oxides is formed from the oxygen antibonding p-states and, although the band gap in Al2O3 is almost twice larger than in CaO, the s-states of both cations. Such a hybrid nature of the conduction band leads to isotropic electron effective masses which are nearly the same for all compounds investigated. This insensitivity of the effective mass to variations in the composition and structure suggests that upon a proper degenerate doping, both amorphous and crystalline phases of the materials will possess mobile extra electrons.

Origin of the Ocean on the Earth: Early Evolution of Water D/H in a Hydrogen-rich Atmosphere

description: The origin of the Earth's ocean has been discussed on the basis of deuterium/hydrogen ratios (D/H) of several sources of water in the solar system. The average D/H of carbonaceous chondrites (CC's) is known to be close to the current D/H of the Earth's ocean, while those of comets and the solar nebula are larger by about a factor of two and smaller by about a factor of seven, respectively, than that of the Earth's ocean. Thus, the main source of the Earth's ocean has been thought to be CC's or adequate mixing of comets and the solar nebula. However, those conclusions are correct only if D/H of water on the Earth has remained unchanged for the past 4.5 Gyr. In this paper, we investigate evolution of D/H in the ocean in the case that the early Earth had a hydrogen-rich atmosphere, the existence of which is predicted by recent theories of planet formation no matter whether the nebula remains or not. Then we show that D/H in the ocean increases by a factor of 2-9, which is caused by the mass fractionation during atmospheric hydrogen loss, followed by deuterium exchange between hydrogen gas and water vapor during ocean formation. This result suggests that the apparent similarity in D/H of water between CC's and the current Earth's ocean does not necessarily support the CC's origin of water and that the apparent discrepancy in D/H is not a good reason for excluding the nebular origin of water.

description: Using the approach offered by quantum speed limit, we show that geometric measure of multipartite entanglement for pure states [Phys. Rev. A 68, 042307(2003)] can be interpreted as the minimal time necessary to unitarily evolve a given quantum state to a separable one.
On the accuracy of DFT exchange-correlation functionals for H bonds in small water clusters II: The water hexamer and van der Waals interactions

description: Second order Moeller-Plesset perturbation theory (MP2) at the complete basis set (CBS) limit and diffusion quantum Monte Carlo (DMC) are used to examine several low energy isomers of the water hexamer. Both approaches predict the so-called "prism" to be the lowest energy isomer, followed by "cage", "book", and "cyclic" isomers. The energies of the four isomers are very similar, all being within 10-15 meV/H2O. This reference data is then used to evaluate the performance of several density-functional theory (DFT) exchange-correlation (xc) functionals. A subset of the xc functionals tested for smaller water clusters [I: Santra et al., J. Chem. Phys. 127, 184104 (2007)] has been considered. Whilst certain functionals do a reasonable job at predicting the absolute dissociation energies of the various isomers (coming within 10-20 meV/H2O), none predict the correct energetic ordering of the four isomers, nor does any predict the correct low total energy isomer. All xc functionals tested either predict the book or cyclic isomers to have the largest dissociation energies. A many-body decomposition of the total interaction energies within the hexamers leads to the conclusion that the failure lies in the poor description of van der Waals (dispersion) forces in the xc functionals considered. It is shown that the addition of an empirical pairwise (attractive) C6/R6 correction to certain functionals allows for an improved energetic ordering of the hexamers. The relevance of these results to density-functional simulations of liquid water is also briefly discussed.

Cephennium tenuissimum

description: Cephennium tenuissimum nov.sp. (Figs 11, 22, 52-53, Map 1)
Type material: Holotype ♂: "E – Murcia, S. de Espuna, Prado Mayor 1100 m, 37°53'18N, 01°33'53W, leg. Andujar 29.3.2007 / Holotypus ♂ Cephennium tenuissimum sp. n. det. V. Assing 2020" (cAss). Paratypes: 1♂, 6♀♀: same data as holotype (cAss).
Etymology: The specific epithet is the superlative of the Latin adjective tenuis (thin, slim) and alludes to the conspicuously slender habitus.
Description: Minute species; body length 0.8-0.9 mm. Habitus (Fig. 11) conspicuously slender, body rather weakly convex in cross-section. Colouration reddish-yellow.
Eyes completely reduced, without so much as rudiments left. Antenna strongly incrassate; antennomeres III-X transverse, V-VII approximately twice as broad as long, and VIII–X more than twice as broad as long.
Pronotum very slender, approximately as long as broad, broadest near anterior angles, weakly convex in cross-section, with indistinct median sulcus in posterior half; punctation moderately dense and fine, barely noticeable; interstices without microsculpture.
Elytra slender and weakly convex in cross-section, broader than pronotum, anteriorly each with a tomentose impression; supra-humeral carina moderately distinct, approximately as long as the combined length of the basal four to five antennomeres; punctation fine; interstices without microsculpture.
♂: tibiae without distinct modifications; metaventrite shallowly impressed; aedeagus (Figs 52-53) broad, 0.23 mm long; ventral process of triangular shape and apically acute; internal structures very small; parameres basally broad, gradually tapering apicad, apically moderately thin and with short apical seta, reaching apex of median lobe.
Comparative notes: Cephennium tenuissimum is readily distinguished from all other Iberian congeners by its conspicuously slender habitus, strongly incrassate antennae, the complete absence of eyes, and by the shape of the aedeagus.
Distribution and natural history: The type locality (Fig. 22) is identical to that of C. espunae (Map 1). Unlike that species, however, the type material of C. tenuissimum was not sifted, but exclusively collected by soil-washing.

description: For a branched cover between two closed orientable surfaces, the Riemann-Hurwitz formula relates the Euler characteristics of the surfaces, the total degree of the cover, and the total length of the partitions of the degree given by the local degrees at the preimages of the branching points. A very old problem asks whether a collection of partitions of an integer having the appropriate total length (that we call a candidate cover) always comes from some branched cover. The answer is known to be in the affirmative whenever the candidate base surface is not the 2-sphere, while for the 2-sphere exceptions do occur. A long-standing conjecture however asserts that when the candidate degree is a prime number, a candidate cover is always realizable. In this paper we analyze the question from the point of view of the geometry of 2-orbifolds, and we provide strong supporting evidence for the conjecture. In particular, we exhibit three different sequences of candidate covers, indexed by their degree, such that for each sequence: (1) The degrees giving realizable covers have asymptotically zero density in the naturals; (2) Each prime degree gives a realizable cover.

Nurses’ care preferences and the quality of nursing care : comparison of the characteristics and the nursing care received for selected high and low preference hospitalized patients
Creators: name: Garry, Helen Bernice
Publisher: name: University of British Columbia

description: In a field study thirty-three Registered Nurses were requested to select, from the patients currently on their nursing units, those patients who were perceived as most or least preferred patients by the majority of the unit nurses. The patient sample size included forty least preferred and forty most preferred patients. After the preference selection each nurse responded to questions which identified their perceptions of the socio-economic, and illness status of the selected patients. A patient behaviour rating scale was scored by each nurse for each patient. The scale included thirty-six adjective descriptors, distributed equally between conforming and nonconforming patient behaviours. 'Problem' patients were well described by the nonconforming or deviant behavioural adjectives while the most preferred patients were described as being very conforming or compliant patients—cooperative, easy to please, considerate and appreciative. The data also revealed that patients with a lengthy hospitalization, a chronic illness or a poor prognosis were least preferred by the nurses. The effects of nurse care preferences were analyzed in relation to the influence on the quality of nursing care received by each of the patient preference groups. The findings revealed that the quality of nursing care does differ for the high and low patient preference groups but the only significant quality score difference appeared in the psychosocial needs category. Three of the study's null hypotheses were accepted. Nurse care preferences were not systematically related to: 1. the demographic characteristics of the patients; 2. the patients' socio-economic status; or 3. the patient needs classification (workload). Three hypotheses were rejected. Nurse care preferences were significantly related to: 1. the illness status of the patients; 2. the behavioural descriptions of the patients; and 3. the quality of nursing care. The meaningfulness of these findings and the implications for further research are considered.
