description: We characterize the ability of the ALHAMBRA survey to assign accurate photo-z's to BLAGN and QSOs based on their ALHAMBRA very-low-resolution optical-NIR spectroscopy. A sample of 170 spectroscopically identified BLAGN and QSOs have been used together with a library of templates (including SEDs from AGN, normal, starburst galaxies and stars) in order to fit the 23 photometric data points provided by ALHAMBRA in the optical and NIR (20 medium-band optical filters plus the standard JHKs). We find that the ALHAMBRA photometry is able to provide an accurate photo-z and spectral classification for ~88% of the spectroscopic sources over 2.5 deg^2 in different areas of the survey, all of them brighter than m678=23.5 (equivalent to r(SLOAN)~24.0). The derived photo-z accuracy is better than 1% and comparable to the most recent results in other cosmological fields. The fraction of outliers (~12%) is mainly caused by the larger photometric errors for the faintest sources and the intrinsic variability of the BLAGN/QSO population. A small fraction of outliers may have an incorrectly assigned spectroscopic redshift. The definition of the ALHAMBRA survey in terms of the number of filters, filter properties, area coverage and depth is able to provide photometric redshifts for BLAGN/QSOs with a precision similar to any previous survey that makes use of medium-band optical photometry. In agreement with previous literature results, our analysis also reveals that, in the 04). These results are relevant for the design of future optical follow-ups of surveys with a large fraction of BLAGN, as it is the case for X-rays or radio surveys.

A Qualitative Descriptive Exploration of the Determinants of Subjective Social Status and the Pathways Through Which Subjective Social Status Shapes Health and Well-Being

description: Abstract Introduction: Socioeconomic position (SEP) is traditionally measured using objective indicators (i.e. income, occupation, education) which may not capture the many pathways through which health inequities are generated. The MacArthur Scale of Subjective Social Status (SSS) is a subjective measure of SEP thought to reflect individuals’ perceptions of their social position, with high predictive utility for health. Despite the scale’s utility, there is limited research investigating the factors and reference groups that shape SSS. The mechanisms through which SSS shapes health also remain unclear, with literature suggesting both materialistic and psychosocial explanations. Objectives: Our study explored the factors and reference groups that working-aged adults consider when evaluating their SSS, and the pathways through which they perceive these factors shape their health and well-being. Methods: Our study employed qualitative descriptive methodology. We recruited 25 adults living in Alberta, aged 30-50, to participate in think-aloud style, semi-structured interviews. Data was analyzed using a semi-deductive, directed content analysis approach. Results: Four major themes summarized participants’ experiences: 1) The significance of reference groups in shaping SSS; 2) The big 3 determinants of SSS - Income, occupation, education; 3) Unique circumstances lead to unique conceptualizations of SSS; and 4) SSS affects mental wellbeing Conclusions: The primary determinants of SSS in working-aged adults in Canada are income, occupation and education. Additional determinants include gender, health and disability, and racial identity. Reference groups also significantly shaped SSS and differed across individuals. Study findings demonstrated that SSS shaped mental well-being through both materialist and psychosocial pathways, which suggests that researchers and policymakers must act upon structural SDH, especially income, education, and occupation, as well as upon the psychosocial stress resulting from social comparisons to reduce inequities in health.

description: Graphene/(Poly)vinyl alcohol (PVA) composite film with thickness $60 μm$ were synthesized by solidification of a PVA solution comprising of dispersed graphene nanosheets. The close proximity of the graphene sheets enables the fluctuation induced tunneling of electrons to occur from one sheet to another. The dielectric data show that the present system can be simulated to a parallel resistance-capacitor network. The high frequency exponent of the frequency variation of the ac conductivity indicates that the charge carriers move in a two-dimensional space. The sample preparation technique will be helpful for synthesizing flexible conductors.

description: In this work we study the influence of populations mobility on the spread of a vector-borne disease. We focus on the chikungunya epidemic event that occurred in 2005-2006 on the Réunion Island, Indian Ocean, France, and validate our models with real epidemic data from the event. We propose a metapopulation model to represent both a high-resolution patch model of the island with realistic population densities and also mobility models for humans (based on real-motion data) and mosquitoes. In this metapopulation network, two models are coupled: one for the dynamics of the mosquito population and one for the transmission of the disease. A high-resolution numerical model is created out from real geographical, demographical and mobility data. The Island is modeled with an 18 000-nodes metapopulation network. Numerical results show the impact of the geographical environment and populations' mobility on the spread of the disease. The model is finally validated against real epidemic data from the Réunion event.

description: Extreme weather caused by climate change has reduced food security and adversely impacted ecosystems, including in Calgary’s network of 64 public community gardens. Increased instances of heat waves, drought, and hail have negatively impacted food production in Calgary’s community gardens. Developing the resilience of food grown in community gardens to extreme weather will safeguard a food source, which supplements gardeners’ diets and is donated to local charitable food organizations and ensure ongoing vibrancy of public space allocated to community gardens in Calgary. In this thesis, I ask how can food production in Calgary’s community gardens be resilient to increasing extreme weather events? In this study I interviewed four Community Garden Coordinators and five gardeners who were growing food in community gardens and distributed a questionnaire to all community gardens in Calgary, receiving 53 gardener responses. The interview and questionnaire questions gathered gardeners’ perspective relating to four research questions. How is food production in Calgary’s community gardens impacted by extreme weather events? How have individual gardeners in Calgary’s community gardens adapted food production strategies to extreme weather events? How have community gardens used cooperation to increase resilience of food production to extreme weather events? What garden design strategies were implemented to adapt food production to extreme weather? Themes identified in the responses were analyzed using the principles of social ecological resilience. This analysis indicated improvements are required in in Calgary’s community gardens to increases resilience of food production to extreme weather. This work highlights that regular meetings, communication, experimentation, and knowledge transfer are crucial to ensuring effective implementation of strategies to build resilience of food production to extreme weather. Increasing soil water retention, building microclimates, and planting adapted plant varieties are highlighted as effective strategies. This work fills a gap in knowledge by identifying strategies that build resilience of food production in Calgary’s community gardens to extreme weather.

description: The study of magnetic fields of cool chemically peculiar stars with effective temperatures less than 10 000 K is very important to understand the nature of their magnetism. We present new results of a long-term spectroscopic monitoring of the well-known magnetic star HD 178892. The analysis of spectra taken with the Russian 6-m telescope has revealed a periodic variation of the surface magnetic field from 17 to 23 kG. A revised rotational period of HD 178892 was extracted from the mean longitudinal field: 8.2549 days. We have continued the study of the components of the magnetic binary BD +40^{\circ}175 started by V. Elkin at SAO RAS. Our measurements of magnetically splitted lines in the spectra of each component show the presence of strong magnetic fields in both components. The surface field in the case of the component A was about 14 kG at three different epochs. The component B possesses a slightly weaker field: B_{s} varies from 9 to 11 kG. A preliminary analysis of the chemical abundances allows us to make an assumption about the roAp nature of both components of BD +40^{\circ}175.

description: Reflection is an essential component of high-quality experiential learning for students (Kaipainen et al, 2020; McRae et al., 2018). Using the DEAL model (Ash and Clayton 2009, Loy et al. 2021) in F18, we developed activities to be included as an Online and Blended Component of learning in our course. We asked students to reflect formally and repeatedly on their feedback, and to use these activities to plan next steps in their learning. After several years of iterative improvements to these activities, we wanted to understand how students use reflection. Using thematic analysis (Braun and Clarke 2006), we are reviewing several cohorts of consenting participants to assess whether students’ perceptions of learning align with our course outcomes. Since this data involves three years of teaching in a variety of modalities, we also gain insights into student perceptions of the effects of online and blended course delivery on their learning. In our session, we will briefly review our learnings to date and then, through surveys, engage participants by asking them to examine their own experiences with reflection techniques in connection to teaching and learning in blended and online environments. Lastly, participants will have opportunities to explore developing questions that can inspire more thoughtful reflection in their own teaching contexts. At the end of the session for our session outcomes, participants will have examined how reflection fits into their own teaching practice, generated questions for reflection, and identified building blocks to incorporate these techniques.

description: Osteoarthritis (OA) is the most common form of arthritis and affects the trapeziometacarpal (TMC) joint. While the etiology of OA is still not fully understood, it is a multifactorial disease with biomechanical factors associated in its development. The thumb is estimated to account for over 40% of the hand’s entire function, largely due to the TMC joint. A better understanding of structural and functional changes in TMC OA may improve our understanding of this degenerative joint disease. A recent advancement in computed tomography (CT) now allows for imaging moving joints in vivo. This technique, termed dynamic CT, provides a unique opportunity to quantify joint biomechanics in vivo. In this thesis, novel methodologies are presented that improve processing of dynamic and high-resolution peripheral quantitative CT (HR-pQCT) scans. These methodologies allow for semi-automated quantification of joint space and bone mineral density (BMD) in HR-pQCT scans and biomechanical outcomes from dynamic CT. The methodologies developed in this dissertation drastically reduce processing time for dynamic CT scans compared to previous literature. A cross-sectional study is presented that utilizes HR-pQCT to measure joint space (JS) changes in hand OA, the first of its kind. Maximum JS was significantly greater in OA than controls in the second and third distal interphalangeal (DIP2, DIP3) joints (DIP2: 2.07 mm vs. 1.88 mm; DIP3: 2.01 mm vs. 1.86 mm), and decreased hand function and increased hand disability were associated with increased radiographic TMC OA. A study was conducted to characterize normal TMC joint biomechanics in vivo using the presented methodologies. BMD was computed in anatomical quadrants of the TMC joint, and it was found that the radial-volar quadrant of the first metacarpal (426 mg HA/cm3) and ulnar-volar quadrant of the trapezium (373 mg HA/cm3) were significantly greater than other quadrants. When compared with proximity maps from dynamic CT, areas with high contact corresponded to quadrants with higher BMD. The results from this dissertation provide methodologies to analyze bone and joint changes with HR-pQCT and dynamic CT to better understand hand osteoarthritis.

description: The drop-the-losers design combines a phase 2 trial of k treatments and a confirmatory phase 3 trial under a single adaptive protocol, thereby gaining efficiency over a traditional clinical development approach. Such designs may be particularly useful in the rare disease setting, where conserving sample size is paramount, and control arms may not be feasible. We propose an unconditional exact likelihood (UEL) testing and inference procedure for these designs for a binary endpoint using small sample sizes, comparing its operating characteristics to existing methods. Additional practical considerations are evaluated, including the choice of stagewise sample sizes and effect of ties.
A two element interferometer prototype for the Canadian Hydrogen Intensity Mapping Experiment
Creators: name: Davis, Gregory
Publisher: name: University of British Columbia
Year: 2012

description: The Canadian Hydrogen Intensity Mapping Experiment (CHIME) will measure the distribution of neutral hydrogen in the universe to constrain dark energy models. A two element radio interferometer operating between 425 and 850 MHz was built at the Dominion Radio Astrophysical Observatory as a CHIME technology prototype. The system temperature is approximately 80 K midband, of which almost 40 K is caused by feed loss and ground spill. A band defining filter used in the receiver allows the signal to be alias sampled at 850 MHz and unfolded to 425-850 MHz. Delayed crosstalk between channels in the interferometer causes prominent spectral ripple with 3.8 MHz period in the cross correlations. Further baseline spectral ripple with 41 MHz period is caused by standing waves between the reflector and the feed ground plane. Sky maps between declinations 52° < δ < 73° over the full frequency band were made using a single dish. The accuracy of the maps is limited predominantly by gain fluctuation in the receiver caused by temperature, 1/f amplifier gain variation, and radio frequency interference. Principal component analysis is demonstrated as a foreground removal technique.

If the cut is taken with complete amplitudes on each side, our continuation and expansion around the on-shell configuration produces the finite contribution to the bubble coefficient. Finite parts in the expansion of the external leg counterterms must be included explicitly as well.

description: We study the heavy charged Higgs boson (from 800 GeV to 1500 GeV in this study) in production associated with a top quark at the LHC with the collision energy $\sqrt{s}=14$ TeV. Such a heavy charged Higgs boson can dominantly decay into a top quark and a bottom quark due to its large Yukawa couplings, like in MSSM. To suppress background events and to confirm the signal, we reconstruct the mass bumps of the heavy charged Higgs boson and the associated top quark. For this purpose, we propose a hybrid-R reconstruction method which utilizes the top tagging technique, a jet substructure technique developed for highly boosted massive particles. By using the full hadronic mode of $p p \to H^{\pm} t \to t tb$ as a test field, we find that this method can greatly reduce the combinatorics in the full reconstruction and can successfully reduce background events down to a controlled level. The sensitivity of LHC to the heavy charged Higgs boson with two $b$ taggings is studied and a $9.5σ$ significance can be achieved when $m_{H^\pm} =1 \textrm{TeV}$.

description: We formulate a dynamical real space renormalization group approach to describe the time evolution of a random spin-1/2 chain, or interacting fermions, initialized in a state with fixed particle positions. Within this approach we identify a many-body localized state of the chain as a dynamical infinite randomness fixed point. Near this fixed point our method becomes asymptotically exact, allowing analytic calculation of time dependent quantities. In particular we explain the striking universal features in the growth of the entanglement seen in recent numerical simulations: unbounded logarithmic growth delayed by a time inversely proportional to the interaction strength. The particle number fluctuations by contrast exhibit much slower growth as log(log(t)) indicating blocked particle transport. Lack of true thermalization in the long time limit is attributed to an infinite set of approximate integrals of motion revealed in the course of the RG flow, which become asymptotically exact conservation laws at the fixed point. Hence we identify the many-body localized state with an emergent generalized Gibbs ensemble.

description: In the realm of carbon neutrality, electrochemical CO2 reduction (eCO2R) stands as a pivotal technology for converting carbon dioxide into valuable multi-carbon (C2+) products, such as ethylene (C2H4) and ethanol (C2H5OH). Despite significant strides in achieving high Faradaic efficiency (FE) at industrial-scale current densities, persistent challenges like cathode flooding and (bi)carbonate salt accumulation in alkaline electrolytes continue to pose fundamental concerns. This study addresses these challenges by leveraging ion-conducting polymers (ionomers) to tailor the micro-environment mitigating cathode flooding and (bi)carbonate crossover and thus, enhance the local CO2 availability in eCO2R. Exploring the impact of cation and anion exchange ionomer layers, specifically Nafion and Sustainion XA-9, reveals that a cation infused ultra-thin bilayer configuration significantly reduces cathode flooding and salt accumulation by approximately 58%, outperforming commercial anion exchange membranes (AEM). Initially, a Single Layer Ionomer (SLI) using Sustainion XA-9 proves effective in mitigating cathode flooding due to the back convection of the thin hydrophobic cathode. Despite an impressive initial partial current density towards C2+ products (jC2+) of ~280 mA/cm2, challenges arise concerning (bi)carbonate formation and CO2 loss. Introducing an additional Nafion layer mitigates (bi)carbonate crossover, attributed to controlled OH- and K+ ion transport facilitated by the Nafion layer. However, the introduction of a Bilayer Ionomer (BLI) configuration results in lower C2+ selectivity due to insufficient OH- diffusion to establish the alkaline micro-environment essential for C2+ reaction pathways. Subsequently, incorporating cation infusion in this bilayer ionomer system (Cation Infused Bilayer Ionomer or CIBLI) proves beneficial, promoting C-C bond formation and creating a favorable micro-environment for selective C2+ product generation. The CIBLI system achieves a substantial high partial current density of approximately ~284 mA/cm2 towards C2+ products, maintaining stable eCO2R performance over 24 hours. The scalability of the directly deposited ultrathin CIBLI configuration offers a minimal conversion energy of 117 GJ/ton for C2+ products with an electrolyzer energy efficiency (EE) of 29% at 350 mA/cm2 current density. This one-step CO2 conversion process represents a promising advancement, emphasizing both efficiency and sustainability in carbon recycling technologies.

description: Given the effects of climate change and its significant consequences on plant productivity, it is necessary to evaluate the enzymatic responses of the most important crops such as wheat (Triticum durum L.). We examined the response of foliar peroxidase activity, nitrate reductase, and glutamine synthetase to experimental increments of temperature (+2 °C) under field conditions following conventional agricultural practices. Foliar samples, in both control and warming treatments were taken during growth, tillering and flowering phenophases to test the peroxidase activity. Similarly, nitrate reductase, glutamine synthetase activities, and glutamine content were measured during the heading phenophase. Due to the effects of experimental warming, peroxidase activity significantly increased. The nitrate reductase activity was also higher in the warming treatment, suggesting a high nitrogen metabolism efficiency. Whereas, the increase observed in the glutamine synthetase activity, and consequently the glutamine content, evidenced a biochemical signal of an early senescence due to the effect of warming.

description: In a recent short note [Bergeron H, Gazeau J P, Siegl P and Youssef A 2010 EPL 92 60003], we have presented the nice properties of a new family of semi-classical states for Pöschl-Teller potentials. These states are built from a supersymmetric quantum mechanics approach and the parameters of these "coherent" states are points in the classical phase space. In this article we develop all the mathematical aspects that have been left apart in the previous article (proof of the resolution of unity, detailed calculations of quantized version of classical observables and mathematical study of the resulting operators: problems of domains, self- adjointness or self-adjoint extensions). Some additional questions as asymptotic behavior are also studied. Moreover, the framework is extended to a larger class of Pöschl-Teller potentials.

description: Pyrazoles are ubiquitous structures in medicinal chemistry. We report the first regioselective route to C3-hydroxyarylated pyrazoles obtained through reaction of pyrazole N-oxides with arynes using mild conditions. Importantly, this method does not require the C4 and C5 positions of the pyrazole to be functionalized to observe regioselectivity. Using this method, we completed the synthesis of a recently reported JAK 1/2 inhibitor. Our synthesis produces the desired product in 4 steps from commercially available starting materials.

description: We present a formulation of naturalness made in the framework of Bayesian statistics, which unravels the conceptual problems related to previous approaches. Among other things, the relative interpretation of the measure of naturalness turns out to be unambiguously established by Jeffreys' scale. Also, the usual sensitivity formulation (so-called Barbieri-Giudice measure) appears to be embedded in our formulation under an extended form. We derive the general sensitivity formula applicable to an arbitrary number of observables. Several consequences and developments are further discussed. As a final illustration, we work out the map of combined fine-tuning associated to the gauge hierarchy problem and neutralino dark matter in a classic supersymmetric model.

description: The reactions of bicyclic divinyl ketones display wavelength-dependent changes in product formation. UV irradiation results in the formation of competitive and tricyclic unsaturated ketones that subsequently undergo ring expansion and reaction with a range of nucleophiles. DFT calculations and transient absorption experiments were completed that are consistent with a vinylogous Type II Norrish pathway.

description: Interaction of (2‐diphenylphosphoryl‐3‐iodo‐4‐methoxy‐phenyl) methanol with NaH in DMF at ambient temperature results in the generation of benzyne intermediates that can be trapped by furan or DMF. Trapping with DMF forms 3‐(dimethylaminomethyl)‐2‐hydroxy‐6‐methoxybenzaldehyde demonstrating the simultaneous exchange of three functionalities in a single step. The presence of the alkoxy substituent adjacent to iodine is critical for high regioselectivity addition of DMF. The corresponding bromide or triflate can be used in place of the iodide with equal efficiency. This methodology was used to synthesize the reported structure of gigasol and leading to a structural reassignment of this biscoumarin natural product.
First mass measurements of highly charged, short-lived nuclides in a Penning trap and the mass of 74Rb

description: To date, Vud of the Cabibbo-Kobayashi-Maskawa quark mixing matrix is most precisely determined from superallowed 0⁺ → 0⁺ nuclear β-decays. In addition to half-life, Branching Ratio, and transition energy (called Q_EC-value) of a superallowed decay, theoretical corrections have to be considered to extract Vud. Among those, the isospin symmetry breaking corrections, δC , show discrepancies between different theoretical models, which are critical to be resolved. ⁷⁴Rb has the largest δC of all 13 superallowed β-emitters used to obtain Vud and would carry particular weight to discriminate between models were it not limited by the uncertainty in the Q_EC-value. However, ⁷⁴Rb’s half-life of 65 ms has previously posed a real challenge to the experimental precision in its Q_EC -value, which is best determined by direct mass measurements in Penning traps. In this work, Penning trap mass measurements of short-lived nuclides have been performed for the first time with highly-charged ions, using the TITAN facility. Compared to singly-charged ions, this provides an improvement in experimental precision that scales with the charge state q. Neutron-deficient Rb-isotopes have been prepared in an electron beam ion trap to q = 8 − 12+ prior to the mass measurements. In combination with a Ramsey scheme, this opens the door to unrivalled precision with gains of 1-2 orders of magnitude. The method is particularly suited for short-lived nuclides such as ⁷⁴Rb and its mass has been determined. In the realm of fundamental symmetries studied in low-energy nuclear systems such as in ⁷⁴Rb, the precision achieved by highly-charged ions is essential. For mass measurements motivated by nuclear structure or nuclear astrophysics, where the present experimental precision is already sufficient, this novel technique significantly reduces the measurement time and thus allows one to map the nuclear mass landscape more broadly. In the exploration towards the limits of nuclear existence where experimental efforts typically face shorter half-lives and lower production yields of radioisotopes, the same precision can be achieved by compensating for both challenges with the higher charge state. Finally, highly-charged ions provide opportunities for an unprecedented resolving power to identify low-lying nuclear isomers. This potential has firstly been demonstrated with ⁷⁸,⁷⁸mRbq⁼⁸⁺.
Exploiting Maximum Capillary Pressure and Detachment Energy Synergy for 3D-Printable High Internal Phase Emulsions with Ultra-low Loadings of Water-Wetting Carbon Dots

description: High Internal Phase Emulsions (HIPEs), with internal phase volume fractions exceeding 0.74, hold potential for diverse applications. Nonetheless, their broader adoption is constrained by limitations, including the need for high concentrations of stabilizers and the ability to fine-tune their morphology. This thesis evaluates the capability of two fully water-wetting sub-10 nm asphaltene-derived carbon dots — asphaltene-derived carbon dots 1 (ACD1) and asphaltene-derived carbon dots 2 (ACD2) — for stabilizing oil-in-water (o/w) HIPE. A universal route is introduced to generate o/w HIPEs with ultra-low loading of water-wetting solid stabilizers by exploiting the synergy of high maximum capillary pressure to resist the thinning of liquid films and particle detachment energy. The HIPE formation involves a 2-minute single-step homogenization of ACDs, water, and dodecane. HIPE was generated with a minimal particle loading of 0.025wt% ACD1, capable of emulsifying 0.82 of oil volume fraction. To probe the link between the evolving microstructure and rheological properties, laser scanning confocal microscopy (LSCM), rheometer, and confocal-rheology (LSCM in conjunction with dynamic oscillatory amplitude sweep) were utilized, testing HIPE thixotropy and creep recovery. A correlation between the HIPE microstructure and rheological properties with the emulsion stabilization mechanisms has been established. The result is a HIPE with spherical dispersed droplets, superior thixotropy, shear-thinning behavior, excellent creep recovery, complete structural recovery, and storage stability of more than 6 months, achieved with just 0.075wt% ACD1 loading. Taking advantage of these properties, finely detailed 3D structures have been successfully printed using an ultra-low loading of 0.075wt% ACD1-stabilized HIPE in an extrusion-based 3D printing method at a low extrusion pressure of 4kPa with a nozzle diameter of just 0.400 mm. This addresses the challenges in HIPE 3D printing, like high extrusion pressures and the need for large nozzle sizes or additional chemicals, thereby broadening the potential applications of HIPEs in 3D printing technologies.

Radiative and non-radiative local density of states on disordered plasmonic films

description: We present numerical calculations of the Local Density of Optical States (LDOS) in the near field of disordered plasmonic films. The calculations are based on an integral volume method, that takes into account polarization and retardation effects, and allows us to discriminate radiative and non-radiative contributions to the LDOS. At short distance, the LDOS is dominated by non-radiative channels, showing that changes in the spontaneous dynamics of dipole emitters are driven by non-radiative coupling to plasmon modes. Maps of radiative and non-radiative LDOS exhibit strong fluctuations, but with substantially different spatial distributions.
