Helping junior high and high school students remain interested in science increases the chance

that they will pursue careers in science. However, there are many different ways to trigger or

sustain interest. Utility-value writing assignments represent a type of motivation intervention that

has consistently demonstrated a positive effect on students’ interest and performance in science.

In this paper, we describe expectancy-value theory as the framework giving rise to utility-value

interventions and review evidence of the effectiveness of the intervention. Then we provide

educators with concrete steps for writing and scoring utility-value writing assignments.

Assessing teachers' knowledge and confidence of spelling instruction
Creators: name: Hill, Penny
Publisher: name: University of British Columbia
Year: 2019

description: Nearly one out of five children in the classroom may need special help to attain satisfactory levels of literacy. Research findings indicate that teachers are not sufficiently trained to support students who struggle with reading and reading-related disorders such as dyslexia. From a sample of British Columbia teachers (n = 63) this study sought to measure teachers’ knowledge of basic language concepts, teachers’ knowledge and understanding of the nature of reading difficulties and teachers’ confidence in their ability to remediate reading-related difficulties. The results indicate that teachers’ understanding of reading-related difficulties such as dyslexia, and their knowledge and skill of basic language concepts such as phonology, orthography and morphology is limited and highly variable. Teachers’ knowledge of basic language concepts were similar to previous research whereby teachers performed better on items in which implicit knowledge could be applied to correctly identify a multiple choice answer. Over half (52%) of the teachers believe that the English spelling system is unpredictable. The mean score for spelling tasks which required demonstration of explicit knowledge of the spelling rule when adding a suffix to a word with a silent e; recognizing a word’s origin; when ck is used; what letters signal a soft c; all of the ways to spell “long o”; and the ways to spell the consonant “f” was 1 with a range of 0 - 4 out of 6. Only 14% of educators stated that they felt prepared to teach children with learning disabilities. Correlation analyses (Pearson) were computed to assess the relationship between perceived ability and skill. 71% of teachers’ self-report of confidence to analyze students’ spelling errors to inform instruction was minimal to moderate. 86% of teachers’ self-report of confidence to use assessment to inform instruction was minimal to moderate. Overall, findings suggest that teachers lack the confidence and skills for teacher directed instruction necessary to give at-risk students the foundation they need to learn to read.

A feasibility study on the effect of an Al-C master alloy on the microstructure and mechanical properties of the B319 cast aluminum alloy
Creators: name: Lafortune, Levi Charles
Publisher: name: University of British Columbia
Year: 2019

description: Aluminum alloys have a high strength to weight ratio (x2 of most steel alloys) and are therefore excellent candidates for use in dynamic weight-sensitive designs (e.g. the aerospace, marine, and automotive industries). The B319 aluminum alloy is currently used in complex cast automotive parts, such as the engine block or cylinder head, due to its excellent castability and heat treatability. Improvements to the B319 alloy’s strength and casting characteristics can lead to further weight reduction of parts, which translates to improved vehicle efficiency, lower cost, and reduced green house gas emissions. Grain refinement is a method of increasing material properties without significantly altering the parent alloy. However, production of well dispersed and consistent master alloys to achieve effective grain refinement remains an industrial challenge. This research investigated the effectiveness of a novel Aluminum(Al)-Carbon(C) master alloy for grain refinement of the B319 alloy. The master alloys were synthesized via the spark plasma sintering (SPS) powder metallurgy process, and subsequently characterized by microstructural analysis. Casting experiments were then carried out with the B319 alloy, and the resultant as- cast materials were analyzed. The results showed that a well dispersed Al-C master alloy could be synthesized by SPS, with carbon black powder equally distributed at the aluminum particle boundaries. The carbon was seen to diffuse at the Al-C interface at sintering temperatures of <500°C. Low concentration (1wt% C) and high concentration (2wt% C) master alloys were added to B319 alloy castings at 0.03wt% total C content. Thermal analysis and microscopy showed no change in the solidification reactions, solidification profiles, or microstructure of the B319 alloy after master alloy addition. Grain size evaluation showed a maximum grain size decrease of 17% when a high concentration master alloy was used. Mechanical and fluidity tests further showed either no improvement or marginal property decreases associated with Al-C addition.

description: We investigate the electromagnetic fields generated by a charged particle rotating inside a dielectric cylinder immersed into a homogeneous medium. The expressions for the bound modes of the radiation field are derived in both interior and exterior regions. The radiation intensity for the modes propagating inside the cylinder is evaluated by using two different ways: by evaluating the work done by the radiation field on the charge and by evaluating the energy flux through the cross-section of the cylinder. The relation between these two quantities is discussed. We investigate the relative contributions of the bound modes and the modes propagating at large distances from the cylinder to the total radiation intensity. Numerical examples are given for a dielectric cylinder in the vacuum. It is shown that the presence of the cylinder can lead to the considerable increase of the synchrotron radiation intensity.

In this article, we present a formal conceptual reexamination of the information geometric construction of entropic indicators of complexity for statistical models. Specifically, we present conceptual advances in the interpretation of the information geometric entropy (IGE), a statistical indicator of temporal complexity (chaoticity) defined on curved statistical manifolds underlying the probabilistic dynamics of physical systems.

description: In colocated multiple-input multiple-output (MIMO) radar using compressive sensing (CS), a receive node compresses its received signal via a linear transformation, referred to as measurement matrix. The samples are subsequently forwarded to a fusion center, where an L1-optimization problem is formulated and solved for target information. CS-based MIMO radar exploits the target sparsity in the angle-Doppler-range space and thus achieves the high localization performance of traditional MIMO radar but with many fewer measurements. The measurement matrix is vital for CS recovery performance. This paper considers the design of measurement matrices that achieve an optimality criterion that depends on the coherence of the sensing matrix (CSM) and/or signal-to-interference ratio (SIR). The first approach minimizes a performance penalty that is a linear combination of CSM and the inverse SIR. The second one imposes a structure on the measurement matrix and determines the parameters involved so that the SIR is enhanced. Depending on the transmit waveforms, the second approach can significantly improve SIR, while maintaining CSM comparable to that of the Gaussian random measurement matrix (GRMM). Simulations indicate that the proposed measurement matrices can improve detection accuracy as compared to a GRMM.

description: Time-division SQUID multiplexers are used in many applications that require exquisite control of systematic error. One potential source of systematic error is the pickup of external magnetic fields in the multiplexer. We present measurements of the field sensitivity figure of merit, effective area, for both the first stage and second stage SQUID amplifiers in three NIST SQUID multiplexer designs. These designs include a new variety with improved gradiometry that significantly reduces the effective area of both the first and second stage SQUID amplifiers.

description: We have carried out hydro-dynamical simulations to investigate the formation and evolution of protostar and circumstellar disks from the prestellar cloud. As the initial state, we adopt the molecular cloud core with two non-dimensional parameters representing the thermal and rotational energies. With these parameters, we make 17 models and calculate the cloud evolution ~ 10^4 years after the protostar formation. We find that early evolution of the star-disk system can be qualitatively classified into four modes: the massive disk, early fragmentation, late fragmentation, and protostar dominant modes. In the 'massive disk mode' to which the majority of models belong, the disk mass is greater than the protostellar mass for over 10^4 years and no fragmentation occurs in the circumstellar disk. The collapsing cloud shows fragmentation before the protostar formation in the 'early fragmentation mode'. The circumstellar disk shows fragmentation after the protostar formation in the 'late fragmentation mode', in which the secondary star substantially gains its mass from the circumstellar disk after fragmentation and it has a mass comparable to that of the primary star. The protostellar mass rapidly increases and exceeds the circumstellar disk mass in the 'protostar dominant mode'. This mode appears only when the initial molecular cloud core has a considerably small rotational energy. Comparison of our results with observations indicates that a majority of protostar has a fairly massive disk during the main accretion phase: the circumstellar disk mass is comparable to or more massive than the protostar. It is expected that such a massive disk promotes gas-giant formation by gravitational instability in a subsequent evolution stage.

UniProtKB – a one-stop shop for all we know about the Drosophila nuclear pore complex
Creators: name: Speretta, Elena

Publisher: name: F1000 Research Limited
Year: 2019

description: The UniProtKB database provides the scientific community with a comprehensive, high-quality and freely accessible resource of protein sequence and functional information. It facilitates scientific discovery by organising biological knowledge and enabling researchers to rapidly comprehend complex areas of biology.

The Drosophila melanogaster annotation program at UniProtKB focuses on the manual annotation of characterised proteins and contains 3,549 reviewed entries. This number continues to increase as new information becomes available.

Here we present a systematic review of the Drosophila nuclear pore complex, one of the largest eukaryotic macromolecular assemblies which form channels through the nuclear membrane. Recent studies have shown that the nuclear pore complex functions go beyond that of regulating trafficking; several nucleoporins, which are components of the nuclear pore complex, are involved in chromatin organization, regulation of gene expression and DNA repair. These new functions give the nuclear pore complex an additional role as regulator of many pathways relevant to disease.

In this presentation we will describe the annotation potential Drosophila nucleoporins as an example of how UniProtKB manual biocurators collect and integrate data from a range of resources such as scientific literature, protein sequence analysis tools, other databases and automatic annotation systems to provide a comprehensive and critical review of the most current biological information for a protein. This systematic effort has improved information consistency and searchability for nucleoporins within the database and, once more, makes UniProtKB a unique platform to review all publicly available information and a sketching board for data-driven hypothesis testing.

description: Spectral weight functions are easily obtained from two-point correlation functions and they might be used to distinguish single-particle from multi-particle states in a finite-volume lattice calculation, a problem crucial for many lattice QCD simulations. In previous studies, it is shown that the spectral weight function for a broad resonance shares the typical volume dependence of a two-particle scattering state i.e. proportional to $1/L^3$ in a large cubic box of size $L$ while the narrow resonance case requires further investigation. In this paper, a generalized formula is found for the spectral weight function which incorporates both narrow and broad resonance cases. Within Lüscher's formalism, it is shown that the volume dependence of the spectral weight function exhibits a single-particle behavior for a extremely narrow resonance and a two-particle behavior for a broad resonance. The corresponding formulas for both $A^+_1$ and $T^-_1$ channels are derived. The potential application of these formulas in the extraction of resonance parameters are also discussed.

description: We present a multi-wavelength study of the energetic interaction between the central active galactic nucleus (AGN), the intra-cluster medium, and the optical emission line nebula in the galaxy cluster Sersic 159-03. We use X-ray data from Chandra, high resolution X-ray spectra and UV images from XMM-Newton, Halpha images from the SOAR telescope, HST optical imaging, and VLA and GMRT radio data. The cluster center displays signs of powerful AGN feedback, which has cleared the central regions (r<7.5 kpc) of dense, X-ray emitting ICM. X-ray spectral maps reveal a high pressure ring surrounding the central AGN at a radius of r~15 kpc, indicating an AGN driven weak shock. The cluster harbors a bright, 44 kpc long Halpha+[NII] filament extending from the centre of the cD galaxy to the north. Along the filament, we see low entropy, high metallicity, cooling X-ray gas. The gas in the filament has most likely been uplifted by `radio mode' AGN activity and subsequently stripped from the galaxy due to its relative southward motion. Because this X-ray gas has been removed from the direct influence of the AGN jets, part of it cools and forms stars as indicated by the observed dust lanes, molecular and ionized emission line nebulae, and the excess UV emission.

description: The Arecibo Legacy Fast ALFA (ALFALFA) survey has completed source extraction for 40% of its total sky area, resulting in the largest sample of HI-selected galaxies to date. We measure the HI mass function from a sample of 10,119 galaxies with 6.2 < log (M_HI/M_Sun) < 11.0 and with well-described mass errors that accurately reflect our knowledge of low-mass systems. We characterize the survey sensitivity and its dependence on profile velocity width, the effect of large-scale structure, and the impact of radio frequency interference in order to calculate the HIMF with both the 1/Vmax and 2DSWML methods. We also assess a flux-limited sample to test the robustness of the methods applied to the full sample. These measurements are in excellent agreement with one another; the derived Schechter function parameters are phi* = 4.8 (+/- 0.3) * 10^-3, log (M*/M_Sun) + 2 log(h_70) = 9.96 (+/- 0.2), and alpha = -1.33 (+/- 0.02). We find Omega_HI = 4.3 (+/- 0.3) * 10^-4, 16% larger than the 2005 HIPASS result, and our Schechter function fit extrapolated to log (M_HI/M_Sun) = 11.0 predicts an order of magnitude more galaxies than HIPASS. The larger values of Omega_HI and of M* imply an upward adjustment for estimates of the detection rate of future large-scale HI line surveys with, e.g., the Square Kilometer Array. A comparison with simulated galaxies from the Millennium Run and a treatment of photoheating as a method of baryon removal from HI-selected halos indicates that the disagreement between dark matter mass functions and baryonic mass functions may soon be resolved.

Seismic fragility assessment in the transverse direction of a steel bridge bent considering soil-structure Interaction
Creators: name: Judd, Trevor James Richard
Publisher: name: University of British Columbia
Year: 2019

description: This research developed the analytical seismic fragility of a two-pier hollow cross-sectional steel highway bridge bent prevalent in British Columbia (B.C.). Nonlinear incremental dynamic time history analysis results obtained from SeismoStruct models subjected to ground motion records were used to develop the fragility curves. They represent the probability of exceeding a performance or damage limit state at a specific ground motion intensity. Peak ground accelerations between 0.047g and 2.654g, from a compliment of 12 synthetic ground motion records and 16 scaling steps, were used in the nonlinear incremental dynamic time history models (IDTHM). Seven primary factors were considered to produce 2⁷ different 3D finite element models of steel bridge bent combinations having equivalent soil-structure interaction considering shallow spread footing on soil type III as per Canadian Highway Bridge Design Code CAN/CSA-S6 (CHBDC). Fractional factorial design (FFD) was employed for parametric study, which additionally reduced computing time. Bridge bent factors of height, wall thickness and corrosion were determined to be the most influential primary factors. The FFD predictive models for each damage limit state (LS) were plotted, with a close correlation between the predictive models and the initial bridge for three out of four damage LS at a PGA of 0.24g and 0.76g with a maximum difference of 13% in all models. Fragility curves employing characteristics of CHBDC soil types II, III and IV for moderate to soft soils were developed for specific evaluation of the bridge bent construction style, establishing the influence of soil conditions on the seismic vulnerability of bridge bent designs. Comparison of soil type fragility curves concluded softer soils generally equate to higher probabilities of exceeding a damage LS, with a variation for a smaller cross-sectional bridge bent at moderate and extensive damage limit states. Slight and moderate damage LSs were influenced more at low PGAs of 0.24g and extensive and complete damage LSs at high PGAs of 0.76g.

description: In this paper, we study the tree amplitudes with gluons coupled to gravitons. We first study the relations among the mixed amplitudes. With BCFW on-shell recursion relation, we will show the color-order reversed relation, $U(1)$-decoupling relation and KK relation hold for tree amplitudes with gluons coupled to gravitons. We then study the disk relation which expresses mixed amplitudes by pure gluon amplitudes. More specifically we will prove the disk relation for mixed amplitudes with gluons coupled to one graviton. Using the disk relation and the properties of pure gluon amplitudes, the color-order reversed relation, $U(1)$-decoupling relation and KK relation for mixed amplitudes can also be proved. Finally, we give some brief discussions on BCJ-like relation for mixed amplitudes.

description: We develop a classical bit-flip correction method to mitigate measurement errors on quantum computers. This method can be applied to any operator, any number of qubits, and any realistic bit-flip probability. We first demonstrate the successful performance of this method by correcting the noisy measurements of the ground-state energy of the longitudinal Ising model. We then generalize our results to arbitrary operators and test our method both numerically and experimentally on IBM quantum hardware. As a result, our correction method reduces the measurement error on the quantum hardware by up to one order of magnitude. We finally discuss how to pre-process the method and extend it to other errors sources beyond measurement errors. For local Hamiltonians, the overhead costs are polynomial in the number of qubits, even if multi-qubit correlations are included.

description: Single Co atoms, which exhibit a Kondo effect on Cu(111), are contacted with Cu and Fe tips in a low-temperature scanning tunneling microscope. With Fe tips, the Kondo effect persists with the Abrikosov-Suhl resonance significantly broadened. In contrast, for Cu-covered W tips, the resonance width remains almost constant throughout the tunneling and contact ranges. The distinct changes of the line width are interpreted in terms of modifications of the Co d state occupation owing to hybridization with the tip apex atoms.

Theory of Orbital Magnetization in Solids

Publisher: name: arXiv
Year: 2011
Subjects: subject: Materials Science (cond-mat.mtrl-sci)
subject: FOS: Physical sciences

description: In this review article, we survey the relatively new theory of orbital magnetization in solids-often referred to as the "modern theory of orbital magnetization"-and its applications. Surprisingly, while the calculation of the orbital magnetization in finite systems such as atoms and molecules is straight forward, in extended systems or solids it has long eluded calculations owing to the fact that the position operator is ill-defined in such a context. Approaches that overcome this problem were first developed in 2005 and in the first part of this review we present the main ideas reaching from a Wannier function approach to semi-classical and finite-temperature formalisms. In the second part, we describe practical aspects of calculating the orbital magnetization, such as taking k-space derivatives, a formalism for pseudopotentials, a single k-point derivation, a Wannier interpolation scheme, and DFT specific aspects. We then show results of recent calculations on Fe, Co, and Ni. In the last part of this review, we focus on direct applications of the orbital magnetization. In particular, we will review how properties such as the nuclear magnetic resonance shielding tensor and the electron paramagnetic resonance g-tensor can elegantly be calculated in terms of a derivative of the orbital magnetization.
Ecuador gold supply chain : analysis of government intervention in the artisanal mining sector
Creators: name: Thomas, Maxim Jordan
Publisher: name: University of British Columbia
Year: 2019

description: The government of Ecuador has been attempting to modernize the artisanal and small-scale gold mining (ASGM) sector to increase tax benefits, reduce pollution, reduce money laundering and formalize informal miners. One of the strategies to help legitimize the supply chain is a program implemented by the Central Bank of Ecuador (CBE) through its Gold Purchase Program in Sangolqui that focuses on the ASGM sector. The attraction for miners to sell gold in Sangolqui is due to the international price paid by CBE for their gold, as well as 0% deductions for service and 0% IVA. The main hurdles to expand the CBE include:1) distant location of the CBE GPP office in Sangolqui, near Quito (miners take 3 days to go by car or plane from southern Ecuador); 2) Neither local gold buyers nor CBE pay for the silver content in the doré; 3) Lack of security for the miners when travelling to Sangolqui with their gold; 4) Legal inadequacy, as the CBE GPP buys gold only from legal and registered sellers; 5 )The CBE requests full registration of the gold sellers with ARCOM, which is a complex process; and 6) In some cases, the time lag to receive the money from the CBE GPP is too long (up to 14 days). Some suggestions to improve the CBE GPP were generated from the findings of this study, including: 1) The CBE could reinforce its presence and influence in the mining regions by establishing permanent or temporary offices near the production areas; 2) Supply a mobile purchasing unit in an armored car; 3) All of the artisanal miners in the country, formal or not, should be able to sell gold to CBE GPP after doing a simple registration; 4) Reduction of the 2% tax charged by the CBE as an additional incentive; 5) CBE and ARCOM could organize the ASGM in cooperatives, thereby creating a mechanism to buy large amounts of gold, which would reduce travel costs; 6) CBE could establish a partnership with large–scale conventional mining companies to purchase gold from ASGM.

description: In this paper, robust transceiver design based on minimum-mean-square-error (MMSE) criterion for dual-hop amplify-and-forward MIMO relay systems is investigated. The channel estimation errors are modeled as Gaussian random variables, and then the effect are incorporated into the robust transceiver based on the Bayesian framework. An iterative algorithm is proposed to jointly design the precoder at the source, the forward matrix at the relay and the equalizer at the destination, and the joint design problem can be efficiently solved by quadratic matrix programming (QMP).

HYDROPOWER DEVELOPMENT POTENTIAL AND OPTIMUM OPTION IN RIVER BASIN (IN TIGRAY, NORTH ETHIOPIA)
Creators: name: Minch, Arba
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2004

description: The Ghiba river basin  in Tigray regional state,  North  Ethiopia,  has catchment
area of 5163km2,
the  length of  the main water course  is 236.4km, with a total
fall  of  2030m.  The  average  annual  rainfall  over  the  basin  is  665.5mm  and
annual  runoff volume of  1372milliom m3.
There  are eleven  storage  sites and
9  cascades  planned  (identified)  in  the  river  based  on  various  established
criteria:  head,  discharge  (reservoir  volume),  geology,  etc.  The  potential
storage  sites  are:  (1)  Suluh,  (2)  Genfel-1,  (3)  Genfel-2,  (4)  Genfel-3,  (5)
Genfel-4,  (6) Genfel-5,  (7) Agulae,  (8) Meskila-1,  (9) Meskila-2,  (10) Meskila-
3  and  (11)  Ghiba.  All  the  cascades  are  located  on  the  main  rivers
downstream  of  all  the  storage  sites  with  the  first  cascade  being  a  dam
scheme.  The  objective  of  this  study  is  to  estimate  hydropower  potential  at
each  site of  interest as well as  the whole basin, and  to  select an optional site
based  on  the  average  power  out  put  (Pm)  at  site  that  could  reach  selected
demand centres.
Hydropower  development  potential  of  the  Ghiba  basin  is  estimated.
Hydrologic study was  carried  out,  using  existing  discharge  data  recorded  at
the  gauging  stations  available  for  the  basin,  and  rainfall  gauging  stations  in
or nearby the  basin.  Due  to  significant missing data  in  rainfall  and  runoff,  as
well  as  poor matching  of  recorded  periods,  eleven  years  of  monthly  rainfall
and  concurrent  runoff  data  was  used.  The  missing  records  in  rainfall  data Hydropower Development  Potential and Optimum Option In Ghiba River Basin
v
The water resources potential,  at the  ungauged sites  (hydro sites) have  been
estimated  by applying the  relationships developed at gauge sites.
To  estimate  the  energy  potential  of  the  hydropower  sites  two  analytical
techniques  were  used  The  Flow  Duration  Curve  (FDC)  method  and  the
Sequential  Stream  Flow  Routing  (SSR) method.  Therefore,  the  total  annual
energy  potential  from  FDC  is170.27GWh  and  from  the  SSR  analysis  is
597  .179GWh.  In  addition,  822GWh  of  energy  could  be  harnessed  from  the
cascading systems.
All  the  hydro  sites are  assumed  to  be  connected  to  two  near by grid  centers
at Wukro and Mekelle. Selection of an optimal  site was  done by  ranking  site:
(1)  based  on  limited  criteria,  topography,  hydrology  and  proximity  to  load
centers,  (2)  based on the power out puts  reached  the demand centers. Thus,
the site with  the highest rank would  be  the optimal site.
This  study  thus  concludes  that,  the  total  hydro-energy  that  could  be
harnessed  from  the whole  basin  is  about  1419 GWh/  year  and  the  optimal
site, which should be  implemented first,  is the Ghiba storage  hydro site.
