description: We analyze a set of volume limited samples from the SDSS to study the dependence of galaxy colour on different environments of the cosmic web. We measure the local dimension of galaxies to determine the geometry of their embedding environments and find that filaments host a higher fraction of red galaxies than sheets at each luminosity. We repeat the analysis at a fixed density and recover the same trend which shows that galaxy colours depend on geometry of environments besides local density. At a fixed luminosity, the fraction of red galaxies in filaments and sheets increases with the extent of these environments. This suggests that the bigger structures have a larger baryon reservoir favouring higher accretion and larger stellar mass. We find that the mean colour of the red and blue populations are systematically higher in the environments with smaller local dimension and increases monotonically in all the environments with luminosity. We observe that the bimodal nature of the galaxy colour distribution persists in all environments and all luminosities, which suggests that the transformation from blue to red galaxy can occur in all environments.

description: Early art historians denigrated Spanish Golden Age polychrome sculpture as utilitarian (i.e., serving a solely ecclesiastical function), stylistically stagnant, and without a complex philosophical base.- '"Do This in Remembrance of Me': Eucharistic Theology, Mysticism, and Empathy in Spanish Golden Age Polychrome Sculpture" builds upon recent advancements in scholarship to argue for a more complex understanding of these eerily naturalistic sculptures and how they may have been interpreted vis-a-vis empathetic worship. Early modem Spanish society was intricately tied to the country's unique religiosity. Taking into consideration possible influences such as the Spanish Inquisition, Tridentine decrees on sacred art and the Eucharist, popular sacramental confraternities, and contemporary Spanish mysticism, an argument for a more profound interpretation and appreciation of Spanish polychrome sculpture is presented. Ultimately, the findings in "'Do This in Remembrance of Me'" will help to further the study of these magnificent works, and bolster the sculptures' scant historiography.

description: Image compression, as one of the fundamental low-level image processing tasks, is very essential for computer vision. Tremendous computing and storage resources can be preserved with a trivial amount of visual information. Conventional image compression methods tend to obtain compressed images by minimizing their appearance discrepancy with the corresponding original images, but pay little attention to their efficacy in downstream perception tasks, e.g., image recognition and object detection. Thus, some of compressed images could be recognized with bias. In contrast, this paper aims to produce compressed images by pursuing both appearance and perceptual consistency. Based on the encoder-decoder framework, we propose using a pre-trained CNN to extract features of the original and compressed images, and making them similar. Thus the compressed images are discernible to subsequent tasks, and we name our method as Discernible Image Compression (DIC). In addition, the maximum mean discrepancy (MMD) is employed to minimize the difference between feature distributions. The resulting compression network can generate images with high image quality and preserve the consistent perception in the feature domain, so that these images can be well recognized by pre-trained machine learning models. Experiments on benchmarks demonstrate that images compressed by using the proposed method can also be well recognized by subsequent visual recognition and detection models. For instance, the mAP value of compressed images by DIC is about 0.6% higher than that of using compressed images by conventional methods.

description: Background: Throughout history, disease outbreaks have affected humans, and low health literacy (HL) is usually associated with poor health care and prevention, as well as self-efficacy (SE) and reduced Satisfaction with Life (SWL). Purpose: This study investigated the current status and relationship of HL, SE, and SWL of college students in Macao. Methods: A total of 553 valid samples aged 18 to 25 (M=20.4 ±1.16) were collected by stratified and convenient sampling methods in Macao. Three measurement tools included HLS-EU-Q (α = .94), GSES (α = .87), and SWLS (α=.89) were verified validity and reliability. Data were analyzed by SPSS 24.0 with the methods of t-test, one-way ANOVA, and correlation and regression analysis. Result: Overall, the key findings include (1) college students in Macao respectively met a medium level of HL (M=3.6, SD=0.53), SE (M=6.7, SD=1.3), and SWL (M=6.2, SD=1.8). (2) there is a significant difference among various background variables (gender, region, and living environment), (3) there is a positive relationship among HL, SE, and SWL, HL, and SE had a 34.1% explanation on SWL (R²=.341, β=.717, p<0.001). Conclusions: The result is in agreement with other health-related studies. The findings suggested that the higher HL, the higher SWL. Even College students in Macao reached the medium level of HL, SE, and SWL, educational expansion, and community attention are needed. It also assumed that the association between HL and SWL might be mediated by SE.

description: The choroid provides oxygen and nourishment to the outer retina thus is related to the pathology of various ocular diseases. Optical coherence tomography (OCT) is advantageous in visualizing and quantifying the choroid in vivo. (1) The lower boundary of the choroid (choroid-sclera interface) in OCT is fuzzy, which makes the automatic segmentation difficult and inaccurate. (2) The visualization of the choroid is hindered by the vessel shadows from the superficial layers of the inner retina. In this paper, we propose to incorporate medical and imaging prior knowledge with deep learning to address these two problems. We propose a biomarker infused global-to-local network for the choroid segmentation. It leverages the choroidal thickness, a primary biomarker in clinic, as a constraint to improve the segmentation accuracy. We also design a global-to-local strategy in the choroid segmentation: a global module is used to segment all the retinal and choroidal layers simultaneously for suppressing overfitting and providing global structure information, then a local module is used to refine the segmentation with the biomarker infusion. To eliminate the retinal vessel shadows, we propose a pipeline that firstly use anatomical and OCT imaging knowledge to locate the shadows using their projection on the retinal pigment epithelium layer, then the contents of the choroidal vasculature at the shadow locations are predicted with an edge-to-texture generative adversarial inpainting network. The experiments show our method outperforms the existing methods on both the segmentation and shadow elimination tasks. We further apply the proposed method in a clinical prospective study for understanding the pathology of glaucoma by detecting the structure and vascular changes of the choroid related to the elevation of intra-ocular pressure.

description: Background: Physical inactivity is a leading risk factor for many of Canada’s major chronic diseases. Research shows that physical activity (PA) improves overall health and cognitive functioning, which is important in academia (ParticipACTION, 2021). The purpose of this study was to determine the effectiveness of Move More North Shore, a physical activity program designed to increase PA and decrease sedentary behaviour. Program Delivery: Twelve participants were referred from university counselling, medical services, or self-referral (employees only). Student Active Health Coaches (SAHC) provided motivation and support to participants through weekly, one-on-one meetings over an eight-week period, to introduce the habit of PA into their daily lives. Due to COVID-19, program delivery was entirely virtual. Evaluation: Participants completed a pre-intervention interview and post-intervention survey which addressed participant knowledge, attitudes, and behaviours, and feedback on program structure. Significantly more days of PA/week were recorded post-intervention versus pre-intervention t(11) = 3.432, p<0.003 (d = -0.991), M1=1.50 days/week, M2=3.33 days. Participants reported significantly more confidence in maintaining PA post-intervention versus pre-intervention t(10) = 3.786, p<0.002 (d = -1.142), M1=3.36/5 confidence in becoming active, M2=4.18/5 confidence in maintaining PA. Conclusions: The pilot resulted in increased PA levels and confidence, feelings of connectedness, improved well-being, and meaningful learning experiences for SAHCs. Sedentary-time was not significantly different post-intervention, which may be due to reduced emphasis on this outcome and COVID-19 restrictions.

description: Recent experiments have shown that proximity with high-temperature superconductors induces unconventional superconducting correlations in graphene. Here we demonstrate that those correlations propagate hundreds of nanometer, allowing for the unique observation of $d$-wave Andreev pair interferences in YBa$_2$Cu$_3$O$_7$-graphene devices that behave as a Fabry-Pérot cavity. The interferences show as a series of pronounced conductance oscillations analogous to those originally predicted by de Gennes--Saint-James for conventional metal-superconductor junctions. The present work is pivotal to the study of exotic directional effects expected for nodal superconductivity in Dirac materials.

While conspiracy theories are not typically supported by evidence, this doesn’t stop them from blossoming. Conspiracy theories damage society in a number of ways. To help minimise these harmful effects, The Conspiracy Theory Handbook explains why conspiracy theories are so popular, how to identify the traits of conspiratorial thinking, and what are effective response strategies.
Bouncing Models in an Extended Gravity Theory

description: Some bouncing models are investigated in the framework of an extended theory of gravity. The extended gravity model is a simple extension of the General Relativity where an additional matter geometry coupling is introduced to account for the late time cosmic speed up phenomena. The dynamics of the models are discussed in the background of a flat FRW universe. Some viable models are reconstructed for specifically assumed bouncing scale factors. The behavior of the models are found to be decided mostly by the parameters of the respective models. The extended gravity based minimal matter-geometry coupling parameter has a role to remove the omega singularity occurring at the bouncing epoch. It is noted that the constructed models violate the energy conditions, however, in some cases this violation leads to the evolution of the models in phantom phase. The stability of the models are analyzed under linear homogeneous perturbations and it is found that, near the bounce, the models show instability but the perturbations decay out smoothly to provide stable models at late times.

description: The aim of this study was to develop the immunohistochemical method for detection of the Bovine Spongiform Encephalopathy (BSE) specific protein (PrP) in bovine brain tissue that is free from cross reactions. A slaughterhouse surveillance was conducted in two districts (Dhaka and Mymensingh). Around 1000 brain samples were collected from 30 months old cows, slaughtered for human consumption. The brainstem (obex), pyriform lobe, pieces of cerebellum and cerebrum were used to detect BSE specific protein, using an anti PrPsc monoclonal antibody (prionic AG, Switzerland). A labelled Streptavidin Biotin (LSAB) method of immunohistochemical staining for the detection of BSE specific protein (PrPn in paraffin embedded positive tissue sections was developed successfully. PrPsc was detected in the cytoplasm of neurons of positive brain tissues. Some of the brain tissues collected from field showed some gliosis and inflammatory lesions but none of• the lesions were consistent with BSE histopathologically and all of the samples were negative for the PrPsc protein by immunohistochemical method. The developed protocol may be used as tool for the diagnosis of BSE.

description: Background: Active transportation to school can be a valuable opportunity for youth to engage in physical activity. Purpose: To study the relationship between neighborhood safety and school programming with walking/biking to school. Methods: The sample includes 1,883 US youth aged 4-15 years who lived within 3km of their school. The relationship between perceptions of neighborhood safety (collected via questionnaires) and school programming data (collected via interviews with key informants) with self-reported walking/biking to school in the past week was tested using logistic regression. Results: Greater neighborhood safety was associated with increased walking/biking to school (β = 0.24, p = .033). Distance to school was negatively associated, and age and income, positively associated, with walking/biking to school (β = -1.36, p < .001; β = 0.21, p < .001; β = 0.43, p = .002). An interaction between neighborhood safety and school programming was marginally significant (p = .056). Conclusions: To increase walking/biking to school, communities should address neighborhood safety and school programming.

description: The atomic pair distribution function (PDF) technique is employed to probe the atomic local structural responses in naturally double layered manganites \lsmo in the doping range $0.54 \leq x \leq 0.80$. Our low temperature neutron powder diffraction measurements suggest the coexistence of two different Jahn-Teller (JT) distorted MnO$_6$ octahedra when its ordered magnetic structure crosses over from type A ($0.54 \leq x \leq 0.66$) to type C/C$^*$ ($0.74 \leq x \leq 0.90$) ordering. At all doping levels at low temperature the doped holes reside predominantly in the plane of the bilayer. In the type A magnetic ordering regime, the e$_g$ electrons appear to be significantly delocalized in the plane resulting in undistorted octahedra, while in type C/C$^*$ regime, elongated JT distorted octahedra are apparent. This is consistent with the presence of inhomogeneous coexisting delocalized and localized electronic states. No evidence of macroscopic phase separation has been observed. Such nanoscale inhomogeneities may explain the magnetically frustrated behavior observed in the spin disordered ``gap'' region ($0.66 \leq x \leq 0.74$).

description: Background: There is a pressing need to develop interventions to increase physical activity and decrease sedentary behaviour in school-aged children. Yet, a better understanding of the degree to which these interventions might be translated across countries at different levels of human development is required. Purpose: To examine the association between levels of human development and sources of variability in accelerometry-derived measures of moderate-to-vigorous physical activity (MVPA) and sedentary time (ST) in 6022 children aged 9–11 years from 12 countries ranging widely in environmental and socio-cultural contexts. Methods: The study design involved recruitment of students, nested within schools, which were nested within study sites. Total and in-school MVPA and ST were measured by waist-worn accelerometry (Actigraph GT3X+). The Human Development Index (HDI) for each country was obtained from the United Nations Development Programme. Results: Associations among the study variables were examined via multi-level models. Across all study sites, the variance in total MVPA and ST explained at the individual level (50.1% to 97.1%) was greater than the variance explained at the school level (2.9% to 49.9%). Similarly, the variance in in-school MVPA and ST explained at the individual level (28.4% to 95.4%) was higher than the proportion of the variance explained at the school level (4.6% to 71.6%). There were negative correlations between HDI and the variance explained by schools for total MVPA (-0.74; p<0.05), total ST (r=-0.55; p=0.06), in-school MVPA (-0.58; p=0.05), and in-school ST (-0.34; p=0.28). Conclusions: The results indicate that higher levels of human development are associated with lower explained variance in total and in-school levels of MVPA and ST. Such findings suggest that school-based physical activity and sedentary behaviour interventions may be less effective in countries with higher levels of human development, and that individual-level interventions may be more effective in these settings. Funding: This study was funded by The Coca-Cola Company. With the exception of requiring that the study be global in nature, the funder had no role in the conduct of the study or interpretation of data.

description: This work discusses the approximations frequently used to calculate the contribution to pion production in proton-proton scattering near threshold from irreducible pion re-scattering. The reference result is obtained from the quantum mechanical reduction of the corresponding Feynman diagram to Time-Ordered Field Theory diagrams. We conclude that the Distorted Wave Born Approximation is quite adequate at threshold energies and even above. We discuss the choices for the energy of the exchanged pion, both for its propagator and for the piN amplitude describing the re-scattering vertex. The calculation employs a physical model for nucleons and pions -- pseudo-vector coupling for the piNN vertex and realistic amplitudes for the piN re-scattering and for the NN transitions in the initial and final states.

description: Increasingly, children, adolescents and young adults with a diagnosis of gender dysphoria are presenting for care desiring medical interventions to align their bodies and gender identities. For patients for whom pubertal development has progressed to Tanner stage 4 or 5, interventions include treatment with testosterone for birth-assigned males and estrogen for birth-assigned females. For younger children, puberty blockers can delay unwanted physical maturation until a decision is made about either stopping blockers and progressing through their endogenous puberty or initiating gender-affirming hormone treatment. These gender-affirming treatments may compromise gonadal function leading to infertility or biological sterility. Fertility preservation (egg and sperm freezing) prior to gender-affirming hormone treatment offers youth pursuing these treatments options for future biological parenthood. This paper begins with an overview of currently available medical treatments and the costs for procedures in this unique population. Subsequently, a review of both state and federal insurance coverage policies regarding fertility preservation and other fertility care procedures is offered, focusing specifically on the case studies of Illinois, Connecticut, and Rhode Island where recent changes in state insurance codes have expanded coverage for these medical services. Finally, the paper provides an analysis and discussion of relevant qualitative interview data from the Trans Youth Fertility Study (TYFS), an ongoing project using qualitative interviews with transgender youth and parents to investigate their experiences with navigating medical insurance and costs associated with fertility preservation.

description: Despite existing constraints, it remains possible that up to $35\%$ of all dark matter is comprised of compact objects, such as the black holes in the 10-100\,M$_\odot$ range whose existence has been confirmed by LIGO. The strong gravitational lensing of transients such as FRBs and GRBs has been suggested as a more sensitive probe for compact dark matter than intensity fluctuations observed in microlensing experiments. Recently ASKAP has reported burst substructure down to $15μ$s timescales in FRBs in the redshift range $0.3-0.5$. We investigate here the implications of this for the detectability of compact dark matter by FRBs. We find that a sample size of $\sim130$ FRBs would be required to constrain compact dark matter to less than the existing 35$\%$ limit with 95$\%$ confidence, if it were distributed along $\gtrsim 1\,$Gpc-long FRB sightlines through the cosmic web. Conversely, existing constraints on the fraction of compact dark matter permit as many as 1 in $\approx 40$ of all $z \lesssim 0.4$ FRBs to exhibit micro-lensed burst structure. Approximately $170$ FRBs intercepting halos within $\sim 50\,$kpc would be required to exclude the fraction of compact dark matter in each intercepted halo to a similar level. Furthermore, we consider the cumulative effects of lensing of the FRB signal by a macroscopic dark matter distribution. We conclude that lensing from a uniform distribution of compact objects is likely not observable, but suggest that FRBs may set meaningful limits on power-law distributions of dark matter.

description: Obesity is a common and current health issue in the world today, as it poses multiple risks to a person’s physical and mental health. The high intake of sugar sweetened beverages (SSBs) has contributed to the increasing rate of obesity both in Canada and internationally. Factors such as taste, cost, and food environments are among the many considerations that influence beverage choice. In an effort to address this problem, UBC Wellbeing has launched a hydration station pilot project in collaboration with FNH 473 students, which is being implemented as part of the Healthy Beverage Initiative. The Hydration Station Pilot Project aimed to improve the diet quality and lifestyle habits of the UBC community by encouraging tap water consumption over SSBs. Using the Community Organization Theory and Health Belief Model for guidance, this initiative involved the establishment and evaluation of two tap water stations for UBC staff and students to use as an alternative to SSBs. We also developed and distributed two post-intervention surveys as another output and as a means of evaluating the project. We used these online questionnaires to qualitatively and quantitatively assess behavioural changes and level of satisfaction resulting from the hydration stations. It was found that 84% of users increased their water consumption and 50% of users reported a decrease in their SSB intake, indicating that the project had a positive impact on the health of UBC staff and students who used the stations. In addition, the hydration stations were found to be feasible and easy to maintain by caretakers and suggested an interest in expanding the project to implement more stations around campus.

description: Background: Children’s enjoyment and competence of physical activity is directly associated with their physical activity participation. However, there is little evidence exploring gender differences in enjoyment and competence for types of physical activity in children. Purpose: The purpose of this study was to explore children’s enjoyment and competence for physical activity types (high intensity, low intensity, and strength) by gender during Physical Education (PE). Methods: All students performed 11 types of physical activities during their PE warm-up. Children’s enjoyment and competence for each activity were assessed with two items on a 5-point Likert scale (5 = “I enjoyed it a lot,” 5 = “I did really well). Enjoyment and competence scores were generated for each activity type (high, low, strength). A 4 (grade) by 2 (gender) MANCOVA on enjoyment and competence was performed for type of activity. Results: Participants were 402, 2nd-5th grade, children from one diverse elementary school (49.4% female, 59.6% white) in central Texas. Girls reported that they enjoyed low intensity activity (M=4.6, SD =0.6; d=0.3) significantly more than boys (M=4.4, SD =0.7). Boys enjoyed high intensity (M=4.17, SD =0.7; d=0.3) and strength (M=3.96, SD =1.01; d=0.30) activities significantly more than girls (M=3.95, SD =0.75; M=3.67, SD =1.11). There were no significant differences across gender for competence with activity types. Conclusions: Girls reported greater enjoyment of lower intensity activities while boys reported greater enjoyment of high intensity and strength activities. As girls’ enjoyment of PE is lower than for boys, these data highlight the need to consider gender preferences for types of activities (high, low, strength) when designing interventions and PE curriculums for children.

description: A helium boil-off technique was used to measure the energy losses in inductive, multi-layer superconducting solenoids carrying time varying transport currents and comparisons are made with existing loss models. The coils were wound using commercially available, multifilament NbTi conductors of varying filament sizes, twist rates, and conductor geometries. Loss measurements were made for pulsed dc and 60 Hz ac transport currents. The pulsed dc data were taken as a function of peak magnetic field at 10 Hz and as a function of frequency (1-10 Hz) at a constant magnetic field. The 60 Hz ac loss data were taken as a function of magnetic field. Conventional loss models are reviewed and expressions for coil losses for full and partial penetration are developed. The loss data are compared to calculations based on these expressions, but the poor agreement in the case of pulsed dc data indicated that our data was taken for peak fields that (varying from 0.2 T to 1.5 T) correspond to a transition between dominance of full or partial penetration. This data agreed well with a model developed by Ashkin hat predicted such a large transition region. The 60 Hz losses were found to have a hysteresis and a matrix current component. The hysteresis component was found to agree with an expression reported by Sumiyoshi et al. which was developed using the Irie and Yamafuji phenomenological model for flux pinning.

description: The method developed by Gouliermis et al. (2000, Paper I), for the detection and classification of stellar systems in the LMC, was used for the identification of stellar associations and open clusters in the central area of the LMC. This method was applied on the stellar catalog produced from a scanned 1.2m UK Schmidt Telescope Plate in U with a field of view almost 6.5 deg x 6.5 deg, centered on the Bar of this galaxy. The survey of the identified systems is presented here followed by the results of the investigation on their spatial distribution and their structural parameters, as were estimated according to our proposed methodology in Paper I. The detected open clusters and stellar associations show to form large filamentary structures, which are often connected with the loci of HI shells. The derived mean size of the stellar associations in this survey was found to agree with the average size found previously by other authors, for stellar associations in different galaxies. This common size of about 80 pc might represent a universal scale for the star formation process, whereas the parameter correlations of the detected loose systems support the distinction between open clusters and stellar associations.

description: The lack of consensus on the role of the agricultural sector in poverty reduction and pitfalls in impact study methodologies resulted in mixed findings on impact of irrigation. This study explores factors that determine farmer s decision to irrigate and whether access to irrigation water enhances livelihood of the farmers. Cross-sectional data from a survey of 240 smallholder farmers in Wondo Genet, Ethiopia was used for the analysis. Foster-Greer-Thorbecke indices indicated high poverty level among farmers without access to irrigation. Further analysis was undertaken using an endogenous switching regression (ESR) model. The correlation coefficient results proved the existence self-selection and endogeneity. Accordingly, variables like scheme governance, level of water scarcity, and access to network found to be some of variables that significantly affected the farmers decision to irrigate. Model estimates further indicated that access to irrigation resulted in better life conditions when compared to counterfactual situation. Farm income of the households has increased by 107% and 171% for irrigation users and non-users, respectively. Similarly, per adult equivalent consumption expenditure has shown increase by 26% and 57% for irrigation users and non-users.

Nonsequential double ionization with few-cycle laser pulses

description: We investigate differential electron distributions in nonsequential double ionization (NSDI) with linearly polarized, few-cycle pulses, using a classical model based on a laser-assisted inelastic $(e^-,2e^-)$ rescattering mechanism. We show that these yields, as functions of the momentum components parallel to the laser polarization, are highly asymmetric, and strongly influenced by the absolute phase, i.e., the phase difference between the carrier oscillation of a few-cycle laser pulse and its envelope. Indeed, around a critical phase, such distributions change their sign in a radical fashion. This phase dependence provides a possibility for absoute-phase measurements which is, in principle, superior to the schemes involving high-order harmonic generation or above-threshold ionization.

description: Climate variability and climate change pose a threat to the livelihoods of developing countries due to their adverse impacts on infrastructure and other production systems most notable in agriculture where such impacts lead to water and food insecurities. The magnitude of the impacts of climate variability and climate change are location specific and depend on the vulnerability and sensitivity of a locale to those effects. Focused on three provinces in South Africa namely the Gauteng, Limpopo and Mpumalanga provinces, the main objective of the study is to provide empirical results on the vulnerability of the selected provinces to climate change. The study is imperative because of a perceived paucity of private and public systems preparedness to deal with the present and future adverse impacts of climate variability and climate change. The study uses a composite vulnerability index and a fixed effect regression model in the analysis of data. Results showed that the selected provinces were vulnerable to climate change but to different extents. Further, it was observed that food grains production was significantly affected by climatic stressors. The study recommends the provision of efficient irrigation facilities, drought-tolerant crops, dissemination of information on integrated pest management and provision of non-agricultural jobs.
