description: Regarding the sharp growth rate of ICT (information and communication technology)—based mobility services like ridesourcing, it is essential to investigate the impact of these new mobility services on the transport mode choices, particularly on active mobility modes like cycling. This impact is more important in the MENA context (the Middle East and North Africa), where cycling does not constitute the main mobility mode in the modal split of most MENA cities. This paper studies the relationship between the regular use of ICT-based mobility services like ridesourcing and the tendency to cycle to near destinations. This paper contains the analysis of 4431 interviews in two large cities of the MENA region (Cairo and Tehran). This research uses logistic regression to analyze and compare the odds of cycling among regular and non-regular users of ridesourcing by considering the socio-economic, land use, and perception variables. The findings indicate that the odds of cycling among the regular users of ridesourcing are 2.30 and 1.94 times greater than these odds among non-regular ridesourcing users in Tehran and Cairo, respectively. Therefore, the regular users of ridesourcing are more likely to cycle to their near destinations than non-regular ridesourcing users in these cities.

description: The article is devoted to electromagnetic phenomena in the atmosphere. The set of experimental data on the thunderstorm activity is analyzed. It helps to identify a possible physical mechanism of lightning flashes. This mechanism can involve the formation of metallic bonds in thunderclouds. The analysis of the problem is performed at a microphysical level within the framework of quantum mechanics. The mechanism of appearance of metallic conductivity includes the resonant tunneling of electrons along resonance-percolation trajectories. Such bonds allow the charges from the vast cloud charged subsystems concentrate quickly in lightning channel. The formation of metal bonds in the thunderstorm cloudiness is described as the second-order phase transition. A successive mechanism for the process of formation and development of the lightning channel is suggested. This mechanism is associated with the change in the orientation of crystals in growing electric field. Possible consequences of the quantum-mechanical mechanism under discussion are compared with the results of observations.

description: We present a detailed analysis of 108 helium-line (DB) white dwarfs based on model atmosphere fits to high signal-to-noise optical spectroscopy. We derive a mean mass of 0.67 Mo for our sample, with a dispersion of only 0.09 Mo. White dwarfs also showing hydrogen lines, the DBA stars, comprise 44% of our sample, and their mass distribution appears similar to that of DB stars. As in our previous investigation, we find no evidence for the existence of low-mass (M < 0.5 Mo) DB white dwarfs. We derive a luminosity function based on a subset of DB white dwarfs identified in the Palomar-Green survey. We show that 20% of all white dwarfs in the temperature range of interest are DB stars, although the fraction drops to half this value above Teff ~ 20,000 K. We also show that the persistence of DB stars with no hydrogen features at low temperatures is difficult to reconcile with a scenario involving accretion from the interstellar medium, often invoked to account for the observed hydrogen abundances in DBA stars. We present evidence for the existence of two different evolutionary channels that produce DB white dwarfs: the standard model where DA stars are transformed into DB stars through the convective dilution of a thin hydrogen layer, and a second channel where DB stars retain a helium-atmosphere throughout their evolution. We finally demonstrate that the instability strip of pulsating V777 Her white dwarfs contains no nonvariables, if the hydrogen content of these stars is properly accounted for.

PT-symmetric laser-absorber

description: In a recent work, Y.D. Chong et al. [Phys. Rev. Lett. {\bf 105}, 053901 (2010)] proposed the idea of a coherent perfect absorber (CPA) as the time-reversed counterpart of a laser, in which a purely incoming radiation pattern is completely absorbed by a lossy medium. The optical medium that realizes CPA is obtained by reversing the gain with absorption, and thus it generally differs from the lasing medium. Here it is shown that a laser with an optical medium that satisfies the parity-time $(\mathcal{PT})$ symmetry condition $ε(-\mathbf{r})=ε^*(\mathbf{r})$ for the dielectric constant behaves simultaneously as a laser oscillator (i.e. it can emit outgoing coherent waves) and as a CPA (i.e. it can fully absorb incoming coherent waves with appropriate amplitudes and phases). Such a device can be thus referred to as a $\mathcal{PT}$-symmetric CPA-laser. The general amplification/absorption features of the $\mathcal{PT}$ CPA-laser below lasing threshold driven by two fields are determined.

description: Using the generalized Tsallis entropy, the Tsallis holographic dark energy(THDE) was proposed recently. In this paper we analyze the cosmological consequences of the THDE model with an interaction between dark energy and dark matter $Q=H(αρ_{m}+βρ_{D})$. We find that the THDE model can explain the current accelerated cosmic expansion, and it is stable under certain conditions. Furthermore, through investigating the dynamical analysis, we find that there exists an attractor which represents an accelerated expansion phase of the universe. When $β=0$, this attractor corresponds to a dark energy dominated de Sitter solution and the universe can evolve into an era which is depicted by the $Λ$CDM model. The age of universe in this model is also explored.

description: A phenomenology for the deep spatial geometry of loop quantum gravity is introduced. In the context of a simple model, an atom of space, it is shown how purely combinatorial structures can affect observations. The angle operator is used to develop a model of angular corrections to local, continuum flat-space 3-geometries. The physical effects involve neither breaking of local Lorentz invariance nor Planck scale suppression, but rather reply on only the combinatorics of SU(2) recoupling. Bhabha scattering is discussed as an example of how the effects might be observationally accessible.

description: In simulations of a water-like model (ST2) that exhibits a liquid-liquid phase transition, we test for the occurrence of a thermodynamic region in which the liquid can be modelled as a two-component mixture. We assign each molecule to one of two species based on the distance to its fifth-nearest neighbor, and evaluate the concentration of each species over a wide range of temperature and density. Our concentration data compare well with mixture-model predictions in a region between the liquid-liquid critical temperature and the temperature of maximum density. Fits of the model to the data in this region yield accurate estimates for the location of the critical point. We also show that the liquid outside the region of density anomalies is poorly modelled as a simple mixture.

description: In a post-quantum world, where attackers may have access to full-scale quantum computers, all classical password-based authentication schemes will be compromised. Quantum copy-protection prevents adversaries from making copies of existing quantum software; we suggest this as a possible approach for designing post-quantum-secure password authentication systems. In this paper, we show an implementation of quantum copy-protection for password verification on IBM quantum computers. We also share our quantum computation results and analyses, as well as lessons learned.

description: This communication is based on an original approach linking economical factors to technical and methodological ones. This work is applied to the decision process for mix production. This approach is relevant for costing driving systems. The main interesting point is that the quotation factors (linked to time indicators for each step of the industrial process) allow the complete evaluation and control of, on the one hand, the global balance of the company for a six-month period and, on the other hand, the reference values for each step of the process cycle of the parts. This approach is based on a complete numerical traceability and control of the processes (design and manufacturing of the parts and tools, mass production). This is possible due to numerical models and to feedback loops for cost indicator analysis at design and production levels. Quotation is also the base for the design requirements and for the choice and the configuration of the production process. The reference values of the quotation generate the base reference parameters of the process steps and operations. The traceability of real values (real time consuming, real consumable) is mainly used for a statistic feedback to the quotation application. The industrial environment is a steel sand casting company with a wide mix product and the application concerns both design and manufacturing. The production system is fully automated and integrates different products at the same time.

description: The reading of current research-informed publications is an essential component of teacher professional development that has the potential to lead to or reinforce the implementation of effective instructional practices. To our knowledge, no studies have examined kindergarten to grade 12 (K-12) ESL teacher engagement in professional reading related to the teaching and learning of ESL. Therefore, we conducted a survey of K-12 ESL teachers from four Canadian provinces to examine their reading practices. Results revealed that teachers mainly consulted professional newsletter articles to address classroom-related issues and indicated that key stakeholders (e.g., teachers’ associations, school districts, and school principals) do little to enhance teachers’ reading of TESL-related publications. Several recommendations to increase teacher reading engagement are included. La lecture de publications courantes fondées sur la recherche constitue une composante essentielle du développement professionnel des enseignants et une qui a le potentiel d’entrainer la mise en œuvre de pratiques pédagogiques efficaces, ou de renforcer celles-ci. Nous ne connaissons aucune étude ayant examiné l’implication des enseignants K-12 dans la lecture de revues et d’ouvrages spécialisés portant sur l’enseignement et l’apprentissage en ALS. Nous avons donc entrepris une enquête auprès d’enseignants K-12 d’ALS dans quatre provinces canadiennes pour connaitre leurs pratiques quant à la lecture. Les résultats indiquent que les enseignants consultaient surtout des articles de bulletins professionnels pour aborder des questions liées à leur pratique. Les enseignants ont également mentionné que les intervenants principaux (par ex. les associations d’enseignants, les districts scolaires et les directeurs d’école) faisaient peu pour encourager la lecture par les enseignants de publications portant sur l’ALS. Nous présentons plusieurs recommandations pour motiver les enseignants à la lecture.

Overall Dynamic Properties of 3-D periodic elastic composites

description: A method for the homogenization of 3-D periodic elastic composites is presented. It allows for the evaluation of the averaged overall frequency dependent dynamic material constitutive tensors relating the averaged dynamic field variable tensors of velocity, strain, stress, and linear momentum. The formulation is based on micromechanical modeling of a representative unit cell of a composite proposed by Nemat-Nasser & Hori (1993), Nemat-Nasser et. al. (1982) and Mura (1987) and is the 3-D generalization of the 1-D elastodynamic homogenization scheme presented by Nemat-Nasser & Srivastava (2011). We show that for 3-D periodic composites the overall compliance (stiffness) tensor is hermitian, irrespective of whether the corresponding unit cell is geometrically or materially symmetric.Overall mass density is shown to be a tensor and, like the overall compliance tensor, always hermitian. The average strain and linear momentum tensors are, however, coupled and the coupling tensors are shown to be each others' hermitian transpose. Finally we present a numerical example of a 3-D periodic composite composed of elastic cubes periodically distributed in an elastic matrix. The presented results corroborate the predictions of the theoretical treatment.

Quasi-periodic Propagating Signals in the Solar Corona: The Signature of Magnetoacoustic Waves or High-Velocity Upflows?

description: Since the discovery of quasi-periodic propagating oscillations with periods of order three to ten minutes in coronal loops with TRACE and EIT (later with EUVI and EIS), they have been almost universally interpreted as evidence for propagating slow-mode magnetoacoustic (MA) waves in the low-beta coronal environment. We show that this interpretation is not unique. We focus instead on the ubiquitous faint upflows, associated with blue asymmetries of spectral line profiles in footpoint regions of coronal loops, and as faint disturbances propagating along coronal loops in EUV/XR imaging timeseries. The two scenarios are difficult to differentiate using only imaging data, but careful analysis of spectral line profiles indicates that faint upflows are likely responsible for some of the observed quasi-periodic oscillatory signals in the corona. We show that EIS measurements of intensity and velocity oscillations in coronal lines (previously interpreted as direct evidence for propagating waves) are actually accompanied by significant oscillations in the line width that are driven by a quasi-periodically varying component of emission in the blue wing of the line. The faint blue-shifted emission component quasi-periodically modulates the peak intensity and line-centroid of a single Gaussian fit to the profile with the same small amplitudes (respectively a few percent of background intensity, and a few km/s) used to infer the presence of MA waves. Our results indicate that a significant fraction of the quasi-periodicities observed with coronal imagers and spectrographs, previously interpreted as propagating MA waves, are caused by these upflows. The different physical cause for coronal oscillations would significantly impact the prospects of successful coronal seismology using propagating disturbances in coronal loops.

Examining Cultural Capital and Student Achievement: Results of A Meta-Analytic Review

Year: 2017

description: This meta-analysis summarized the relationships between cultural capital and student achievement (155 effect sizes involving 685,393 K-12 students) published in education journals between 1981 and 2015. Results showed a small-to-medium overall mean effect size, and larger individual effect sizes for parental education and parental expectations compared to parent-child cultural participation and discussions. Effect sizes were also larger for older students, reading achievement, and studies published earlier. The results affirm the role of cultural capital in explaining student achievement, and indicate that cultural capital is not a unidimensional construct with unequivocal effects on achievement. Cette méta-analyse résume les rapports entre le capital culturel et le rendement des élèves (ampleur de l’effet =155 comptant 685 393 élèves K-12) publiés dans des revues pédagogiques entre 1981 et 2015. Les résultats indiquent que globalement, l’ampleur moyenne de l’effet est entre petite et moyenne et que l’ampleur de l’effet individuel est plus grande pour l’éducation des parents et les attentes parentales que pour la participation culturelle et les discussions parent-enfant. L’ampleur de l’effet est également plus importante chez les élèves plus âgés, pour le rendement en lecture et dans les études publiées antérieurement. Les résultats affirment le rôle du capital culturel dans le rendement scolaire et indiquent que le capital culturel n’est pas une construction unidimensionnelle ayant des effets clairs et explicites sur le rendement.

Creative experiential learning : engaging people in (micro) cultures of sustainability
Creators: name: Angel, Jeannette Cybèle
Publisher: name: University of British Columbia
Year: 2019

description: This dissertation presents a dynamic model for creative experiential learning that engages people in sustainability challenges and other social practice research. The model’s evolution is described through creative and artistic practice situated in ecologically focused collaborations and through extensive cross-disciplinary encounters with the literature of experiential learning and change, phenomenological writings focused on embodiment, the ethics of care in feminist theory, and Indigenous scholars positioning land-based knowledge paradigms in relation to Western philosophical traditions. The dissertation itself embodies the entangled strands of research in these diverse fields as it investigates what constitutes knowledge and how ways of knowing are shifted, altered, deepened and shared through experience, art and education. The resulting creative methodology and model for creative experiential learning are presented as a useful design and learning approach and reflective research tool that can be activated by artists, scholars, and communities working in transdisciplinary sustainability contexts. At the heart of the model are methods that offer ways to imagine, enact and support creative spaces of interaction that engage people in sustainability through generating “(micro) cultures” – a term used to explore situations and processes that are intimate, focused and specific rather than based on making large-scale system changes. The model aims to generate these spaces in relation to sustainability challenges by orienting a person or people to a core concept: {land-self-people-place}. The dissertation uses this conceptual sign {land-self-people-place} to express a re-visioning of place that is interdependent and nested. Artistic practices contribute, through the concepts of socio-ecological aesthetics, collaborative play and entangled beauty, to creating productive (micro) cultures where people can engage in regenerative actions woven around environmental care. The narrative and lyric inquiry of the dissertation shift into the exploration of a formal assessment of the model in the evaluation processes of two complex interdisciplinary sustainability research projects: case studies evaluating three game play approaches in Future Delta 2.0, a climate change videogame; and collaborative knowledge sharing in The Social Life of Water, a public museum exhibition exploring human-water relationships in the Okanagan.

EVALUATION OF WATER SAVING AND CROP PRODUCTIVITY POTENTIAL  OF DIFFERENT FURROW IRRIGATION APPLICATION METHODS  UNDERTOMATO CROP
Creators: name: YOHANNES CHEKOLE
Publisher: name: National Academic Digital Repository of Ethiopia

description: Irrigation development is increasingly implemented in Ethiopia more than ever. Expansion of
irrigated area combined with efficient management of water will enhance the attainment of
food security and poverty alleviation goals of the country. So improved irrigation
technologies needs to be developed so that water saving and water productivity per unit of
land and water can be increased. Therefore, a field experiment was conducted with the
objectives of investigating the effect of alternate, fixed and conventional furrow irrigation
system on yield and water productivity of Tomato  crop and to identify the level of deficit
irrigation for achieving optimum crop yield in Kara Adishu. The study was conducted using
three levels of irrigation (50%ETc, 75%ETc and control irrigation 100%ETc) and three
irrigation furrow system in 3*3 factorial arrangements in split plot design with three
replications. The analysis of variance for the result of the study indicated highly significant
(P<0.05) different for yield, yield components and WUEs. The highest yield of 42.31 ton/ha
was obtained from the control with CFI which was not significantly (p<0.05) different from
the75%ETc with CFI system. In terms of irrigation and water use efficiency, 50%ETc deficit
irrigation application with CFI system gave the highest IWUE which was significantly
different  from all other treatment combinations. Yield and water use efficiency based
comparison had shown that there was significant difference between the yield, CWUE and
IWUE obtained in the AFI and CFI while the applied water in AFI was reduced by 50%.
Therefore, it can be concluded that increased water  saving and associated water
productivity through the use of 75% with CFI, can solve problem of water shortage which
improve WUE without significant reduction of yield AFI system appears to be a promising alternative for water conservation and labor saving with negligible trade off in yield.

description: Recently, peoples awareness of online purchases has significantly risen. This has given rise to online retail platforms and the need for a better understanding of customer purchasing behaviour. Retail companies are pressed with the need to deal with a high volume of customer purchases, which requires sophisticated approaches to perform more accurate and efficient customer segmentation. Customer segmentation is a marketing analytical tool that aids customer-centric service and thus enhances profitability. In this paper, we aim to develop a customer segmentation model to improve decision-making processes in the retail market industry. To achieve this, we employed a UK-based online retail dataset obtained from the UCI machine learning repository. The retail dataset consists of 541,909 customer records and eight features. Our study adopted the RFM (recency, frequency, and monetary) framework to quantify customer values. Thereafter, we compared several state-of-the-art (SOTA) clustering algorithms, namely, K-means clustering, the Gaussian mixture model (GMM), density-based spatial clustering of applications with noise (DBSCAN), agglomerative clustering, and balanced iterative reducing and clustering using hierarchies (BIRCH). The results showed the GMM outperformed other approaches, with a Silhouette Score of 0.80.

description: Investigation of potential irrigable land and available water resources is an essential for
the development of irrigated agriculture. The study  is  focused on  investigating  land and
water resources potential of Andassa river catchment and preparing geo-referenced maps
of these  resources using GIS. Land  suitability for irrigation development was  identified
by considering the irrigation suitability factors such as slope, soil and land use /land
cover. The analysis result of these factors indicates that 95.17 % of slope, 75.2 % of soil
and 97 % land use/land cover are in the range of highly to marginally suitable for surface
irrigation. The  irrigable land of the area was identified using weighted overlay analysis
of the suitability parameters. The total irrigable land of watershed is about 76.7% which
is potentially suitable for surface irrigation and 23.3% is classified as nonsuitable (N).
Surface water potential of the study area was estimated through stream flow simulations
by SWAT model. The model was calibrated and validated from observed stream flow data
of the watershed using the periods of 1992-2005 and 2006-2012 respectively leaving two
years as “warm up’ ’period.  During calibration and validation, the results of model
performance indicators were in the acceptable range (R2

description: The detection of gravitational waves (GWs) by ground-based laser interferometer GW observatories (LIGO/Virgo) reveals a population of stellar binary black holes (sBBHs) with (total) masses up to $\sim 150M_\odot$, which are potential sources for space-based GW detectors, such as LISA and Taiji. In this paper, we investigate in details on the possibility of detecting sBBHs by the LISA-Taiji network in future. We adopt the sBBH merger rate density constrained by LIGO/VIRGO observations to randomly generate mock sBBHs samples. Assuming an observation period of $4$ years, we find that the LISA-Taiji network may detect several tens (or at least several) sBBHs with signal-to-noise ratio (SNR) $>8$ (or $>15$), a factor $2-3$ times larger than that by only using LISA or Taiji observations. Among these sBBHs, no more than a few that can merge during the $4$-year observation period. If extending the observation period to $10$ years, then the LISA-Taiji network may detect about one hundred (or twenty) sBBHs with SNR $>8$ (or $>15$), among them about twenty (or at least several) can merge within the observation period. Our results suggest that the LISA-Taiji network may be able to detect at least a handful to twenty or more sBBHs even if assuming a conservative SNR threshold ($15$) for ``detection'', which enables multi-band GW observations by space and ground-based GW detectors. We also further estimate the uncertainties in the parameter estimations of the sBBH systems ``detected'' by the LISA-Taiji network. We find that the relative errors in the luminosity distance measurements and sky localization are mostly in the range of $0.05-0.2$ and $1-100°^2$, respectively, for these sBBHs.

description: In the early phases of the product life cycle, the costs controls became a major decision tool in the competitiveness of the companies due to the world competition. After defining the problems related to this control difficulties, we will present an approach using a concept of cost entity related to the design and realization activities of the product. We will try to apply this approach to the fields of the sand casting foundry. This work will highlight the enterprise modelling difficulties (limits of a global cost modelling) and some specifics limitations of the tool used for this development. Finally we will discuss on the limits of a generic approach.

description: Gravitational wave (GW) signals from compact binary coalescences can be used as standard sirens to constrain cosmological parameters if their redshift can be measured independently. However, mergers of stellar binary black holes (BBHs) may not have electromagnetic counterparts and thus have no direct redshift measurements. These dark sirens may be still used to statistically constrain cosmological parameters by combining their GW measured luminosity distances and localization with deep redshift surveys of galaxies around it. We investigate this dark siren method in detail by using mock BBH and galaxy samples. We find that the Hubble constant can be constrained well with an accuracy $\lesssim1\%$ with a few tens or more of BBH mergers at redshift up to $1$ if GW observations can provide accurate estimates of their luminosity distance (with relative error of $\lesssim0.01$) and localization ($\lesssim0.1~\rm{deg}^2$), though the constraint may be significantly biased if the luminosity distance and localization errors are larger. We also introduce a simple method to correct this bias and find it is valid when the luminosity distance and localization errors are modestly large. We further generate mock BBH samples, according to current constraints on BBH merger rate and the distributions of BBH properties, and find that the Deci-hertz Observatory (DO) in a half year observation period may detect about one hundred BBHs with signal-to-noise ratio $\varrho\gtrsim30$, relative luminosity distance error $\lesssim0.02$, and localization error $\lesssim0.01\rm{deg}^2$. By applying the dark standard siren method, we find that the Hubble constant can be constrained to the $\sim0.1-1\%$ level using these DO BBHs, an accuracy comparable to the constraints obtained by using electromagnetic observations in the near future, thus it may provide insight into the Hubble tension.

description: Background: Eye-gaze is an access method used for people with severe motor impairments to communicate when other access methods for augmentative and alternative communication (AAC) are not feasible. The purpose of this research was to conduct a scoping review on eye-gaze as an access technique for AAC. This scoping review uses Light’s communicative competences (i.e., linguistic, operational, social, and strategic) as a framework to analyze recent literature.

Methods: Five databases were searched to find relevant articles that considered eye-gaze as an access method for communicative purposes. Results were charted and analyzed to determine which, if any, communicative competences and associated factors were being targeted in current research.

Results: Sixteen studies were selected for analysis. Of these sixteen, ten studies had an intervention. None of the studies reviewed targeted or measured all areas of communicative competence and associated factors.

Discussion: In order for people to become effective communicators, they must be competent in all the following domains: linguistic, operational, social, and strategic. Approaching future research from a communicative competence framework may be beneficial in improving outcomes for targeted populations.

description: The growth of single and multilayer graphene nano-flakes on MgO and ZrO2 at low temperatures is shown through transmission electron microscopy. The graphene nano-flakes are ubiquitously anchored at step edges on MgO (100) surfaces. Density functional theory investigations on MgO (100) indicate C2H2 decomposition and carbon adsorption at step-edges. Hence, both the experimental and theoretical data highlight the importance of step sites for graphene growth on MgO.
GIS BASED SURFACE IRRIGATION POTENTIAL ASSESSMENT OF RIVER  CATCHMENTS FOR IRRIGATION DEVELOPMENT IN NORTH GOJJAM ABBAY BASIN

Publisher: name: National Academic Digital Repository of Ethiopia

description: Assessing available land and water resources for irrigation is important for planning their use.
Main objective of this study was  assessing the water and land resources potential of river
catchments in North Gojjam for irrigation development and generating suitable map of  these
resources by using Geographic Information System. Watershed delineation, identification of
potential irrigable land, and estimation of irrigation water requirement and surface water
resources of river catchments were the steps  that are followed to assess this irrigation potential.
To identify potential irrigable land, irrigation suitability factors such as soil type, slope, land
cover/use, and distance from water supply (sources) were taken into account.  The irrigation
suitability analysis of these factors indicate that 40.5% of slope, 53.72% soil and 94.4% of land
cover/use  in the study area are in the range of highly suitable to marginally suitable for surface
irrigation system.  Using pair-wise comparison method, overall weighted overlay analysis of
these factors gave potential irrigable land among  suitable land  are 5%. There are four (maize,
onion, potato and pepper) crop were selected under identified irrigable  area and their gross
irrigation demand calculated by using nearby climatic stations. The result revealed that irrigation
requirements of identified command area varies according to nearby climatic station and type of
crops selected. The discharges at un-gauged sites were estimated from gauged sites by applying
runoff coefficient method and area-ratio method and results were obtained on monthly bases. By
comparing gross irrigation demand of irrigable land with available flow in rivers, total  surface
irrigation potential of the study area was obtained as 9,503 ha. Since the suitable land for surface
irrigation is very small, due to the scarcity of water. It is possible to  increase surface irrigation
potential by increasing available water using storage structure.
