description: Highly energetic 157 nm laser irradiation was explored for possible use in the nanolithographic process; 157 nm irradiation of photoresists containing photoacid generators (PAG) was shown to generate acid as it does at longer wavelengths. Irradiation of polymers films that did not contain a PAG was also shown to generate acid but required a higher exposure dose. These polymer films were also shown to generate HF upon 157 nm irradiation. Experiments in solution have shown that 1,1,1,3,3,3-hexafluoro-2-propanol could trap electrons with a rate constant of 6.6 x 1010 M-1s -1. Electrons would be generated by the non-fluorinated moieties of the polymer film upon 157 nm irradiation and subsequently trapped by the fluorinated moieties leading to the release of fluoride, deprotonation at the ionization site would lead to HF formation. Laser flash photolysis of films with 157 nm as the excitation wavelength was attempted, this experiment was technically very challenging because of the high absorbance of most organic compounds, water and oxygen at 157 nm. However, a triplet absorbance for xanthone in perfluorononane was detected. TEMPO and 4-amino-TEMPO were shown to quench the fluorescence of CdSe quantum dots covered with tri-octylphosphine oxide (TOPO). The quenching is size-dependent, being more efficient for the smaller than for the larger quantum dots. Furthermore, 4-amino-TEMPO is more efficient at quenching the fluorescence of quantum dots than TEMPO. Stern-Volmer plots for the quenching of quantum dots by TEMPO are upward curving, indicating distance dependent quenching. The Perrin model was used to analyse the results. 4-Amino-TEMPO was shown to form complexes with quantum dots by electron spin resonance spectroscopy. Downward curving Stern-Volmer plots for fluorescence quenching by 4-amino-TEMPO (4AT) indicate that 4AT may first bind in openings in the TOPO ligand shell and subsequently bind by displacing the TOPO ligands. Prefluorescent probes were developed. The fluorescence of the 4AT-quantum dot complex was restored in the presence of photogenerated radicals from azobisisobutyronitrile (AIBN). UV irradiation of polymer films containing quantum dots was shown to enhance the fluorescence of quantum dots. Quenching by TEMPO and 4AT of quantum dots and subsequent quantum dot fluorescence recovery in channels of photonic crystal fibres was recorded by fluorescence imaging. It is explained by the non-linear quenching observed in solution and by the diffusion of the quantum dot and the quencher in the channels of the photonic crystal fibres.

description: Galaxy mergers are important events that can determine the fate of a galaxy by changing its morphology, star formation activity and mass growth. Merger systems have commonly been identified from their disturbed morphologies, and we now can employ integral field spectroscopy to detect and analyze the impact of mergers on stellar kinematics as well. We visually classified galaxy morphology using deep images (${mu }_{{rm{r}}}=28,mathrm{mag},{mathrm{arcsec}}^{-2}$) taken by the Blanco 4 m telescope at the Cerro Tololo Inter-American Observatory. In this paper we investigate 63 bright (${M}_{{rm{r}}}lt -19.3$) spectroscopically selected galaxies in Abell 119, of which 53 are early type and 20 show a disturbed morphology by visual inspection. A misalignment between the major axes in the photometric image and the kinematic map is conspicuous in morphologically disturbed galaxies. Our sample is dominated by early-type galaxies, yet it shows a surprisingly tight Tully–Fisher relation except for the morphologically disturbed galaxies which show large deviations. Three out of the eight slow rotators in our sample are morphologically disturbed. The morphologically disturbed galaxies are generally more asymmetric, visually as well as kinematically. Our findings suggest that galaxy interactions, including mergers and perhaps fly-bys, play an important role in determining the orientation and magnitude of a galaxy's angular momentum.

Efficient and Effective Cohesive Subgraph Search in Bipartite Graphs
Creators: name: Abidi, Aman
Publisher: name: Swinburne
Year: 2024

description: Bipartite graphs are an interesting structure that can model the relationships between two different types of entities in real-world scenarios such as customer-product and author-paper networks. Finding bipartite cohesive subgraphs is a fundamental problem aiming to find strongly connected subgraphs to better understand such bipartite graphs. The powerful traditional models for searching strongly connected patterns cannot fully explore the deeper insights of bipartite graphs, as they are defined on general graphs. Therefore, in this thesis, we first study the fundamental problem of enumerating all bipartite cohesive subgraphs and then present two new bipartite cohesive subgraph models for distinct real-world scenarios.

description: Background: Global cases of overdose-related deaths attributed to synthetic opioids are reaching epidemic proportion in many jurisdictions. While the main focus of health agencies and the different levels of government has been to combat the cases linked to injection drug use, the deaths attributed to smoking illegal drugs have not gained the same attention. Moreover, little attention has been given to the role of people with past or current experiences of illegal drug use and how their social networks can mitigate the risk of a highly stigmatized behavior such as smoking illegal drugs. Methods: The study concerns the first social network research conducted via a community-based participatory action methodology in two distinct urban (Vancouver) and rural (Abbotsford) centers in British Columbia, Canada. The study will identify the influence of social networks on people who smoke illegal drugs (PWSID) and their adherence to interventions aimed at reducing harm. Through community consultations, members of the Vancouver Area Network of Drug Users and the British Columbia/Yukon Association of Drug War Survivors not only assisted with the design of this research project but also assisted with the data collection, management, protection and entry of demographic, and network information. Discussion: Many traditional qualitative and quantitative methods have not effectively engaged people who use drugs as researchers or collaborators due to stigma related to illegal drug use. The aim of this study is to recognize that everyone within the network of PWSID is a few steps away from harm. Therefore, we aim to reduce the harm associated with smoking of illegal drugs, especially for PWSID that are at the highest risk. At the same time, we hope that the social network research via a participatory community-based approach will mobilize PWSID in the process and offer a different method of knowledge construction from the traditional positivist approaches.
An addictive e-waste problem : policy solutions for reducing the environmental impact of vaping products in Canada
Creators: name: Shilton, Emily
Publisher: name: University of British Columbia
Year: 2025

description: The accelerated growth of vaping in Canada has created a new stream of hazardous and largely unregulated electronic waste. As products that straddle the line between consumer electronics and nicotine delivery systems, vapes occupy a policy gray zone. This regulatory gap poses significant challenges for their safe disposal, recycling, and material recovery. The goal of this thesis is to provide policy recommendations to reduce the environmental impact of vape products through conducting a life cycle assessment (LCA) and consumer survey. A comparative LCA of devices was conducted by first performing a device take-apart and material characterization using X-ray fluorescence (XRF) and Fourier transform infrared (FTIR) spectroscopy. The LCA was developed in OpenLCA using the ecoinvent v3.10 database and ReCiPe 2016 Midpoint (H) indicators. The results showed disposable products have consistently higher climate change impacts than refillable products, with the primary drivers being battery, electronics, and case manufacturing. The survey was administered to 500 adult vape users in the U.S. and Canada, and the results were analyzed using a logistic regression analysis. The responses showed an almost even purchasing split between disposable (57%) versus reusable systems (43%). Additionally, 63% of users reported throwing their devices in the trash as their primary disposal method. Pro-environmental values and norms were statistically significant predictors of both sustainable disposal and intervention support, though not of sustainable purchasing. Based on these findings, four policy interventions were evaluated: i) a ban on disposable vapes, ii) a requirement for all vapes to include removable batteries, iii) the development of recycling programs funded through Environmental Handling Fees (EHF), and iv) recycling incentivization via deposit-refund systems. The results of this study strongly recommend the implementation of a disposable vape ban in Canada, as it could annually reduce global greenhouse gas emissions by 89.7 million kg CO₂-eq and prevent 2 million kg of lithium polymer batteries from entering Canadian waste streams. While battery removal mandates may further enhance safety and recyclability, they would require increased regulatory oversight. Recycling initiatives show high potential but warrant further research to assess cost-effectiveness and implementation feasibility.

description: Differential privacy (DP) is a class of mathematical standards for assessing the privacy provided by a data-release mechanism. This work concerns two important flavors of DP that are related yet conceptually distinct: pure $\varepsilon$-differential privacy ($\varepsilon$-DP) and Pufferfish privacy. We restate $\varepsilon$-DP and Pufferfish privacy as Lipschitz continuity conditions and provide their formulations in terms of an object from the imprecise probability literature: the interval of measures. We use these formulations to derive limits on key quantities in frequentist hypothesis testing and in Bayesian inference using data that are sanitised according to either of these two privacy standards. Under very mild conditions, the results in this work are valid for arbitrary parameters, priors and data generating models. These bounds are weaker than those attainable when analysing specific data generating models or data-release mechanisms. However, they provide generally applicable limits on the ability to learn from differentially private data - even when the analyst's knowledge of the model or mechanism is limited. They also shed light on the semantic interpretations of the two DP flavors under examination, a subject of contention in the current literature.
description: This is an extended version of the conference paper [9]. Along with some lesser additions, Sections 7 and 8 on Pufferfish privacy are new; and Lemma 57, Theorem 9 (these two results correspond to Theorem 9 in [9]), Theorem 11 (Theorem 8 in [9]) and Theorem 14 (Theorem 10 in [9]) all contain minor corrections

description: Background Floating-Harbor syndrome is a rare autosomal dominant short stature syndrome with retarded speech development, intellectual disability and dysmorphic facial features. Recently dominant mutations almost exclusively located in exon 34 of the Snf2-related CREBBP activator protein gene were identified to cause FHS. Methods Here we report the genetic analysis of 5 patients fulfilling the diagnostic criteria of FHS obtained by Sanger sequencing. All of them presented with short stature, speech delay as well as psychomotor delay and typical facial dysmorphism. Three patients showed a good response to growth hormone treatment. Results Two patients demonstrate novel, heterozygous de novo frameshift mutations in exon 34 (c.7396delA and c.7218dupT) leading to premature stop mutations in SRCAP (p.Val2466Tyrfs*9 and p.Gln2407Serfs*36, respectively). In two further patients we found already known SRCAP mutations in exon 34, c.7330C > T and c.7303C > T, respectively, which also lead to premature stop codons: p.Arg2444* and p.Arg2435*. In one patient, we identified a novel de novo stop mutation in exon 33 (c.6985C > T, p.Arg2329*) demonstrating that not all FHS cases are caused by mutations in exon 34 of SRCAP. Conclusions Our data confirm a mutational hot spot in the final exon of SRCAP in the majority of FHS patients but also show that exon 33 of this gene can be affected.

description: Wild pigs (Sus scrofa) are an invasive species in the mainland United States, where they are responsible for a wide range of negative impacts including damage to crops, livestock depredation as well as disease transmission, destruction of property and ecosystems, and depredation of wildlife. This manuscript summarizes a recent survey-based effort to estimate wild pig damage and control costs incurred by livestock producers by state and livestock type. The survey was distributed by the U.S. Department of Agriculture National Agricultural Statistical Service in the summer of 2021 to a sample of livestock producers in the 13-state region. Findings indicated that predation and disease-related damage can be substantial in certain states and for certain types of livestock. In particular, damage to livestock operations, specifically cattle (Bos taurus) operations, in Texas, USA, was substantially higher than damage in other states and types of livestock operations. However, these amounts are dwarfed by the expenditure incurred by damage to property and the rooting of pasture. When aggregating across the entire 13-state region, we estimated that damage and control costs to livestock producers summed in 2020 to an annual amount of >$650 million USD, driven by damage to property ($375.5 million USD) and the rooting of pasture ($192.9 million USD). The findings from this survey provide valuable information to estimate the full scope of the economic impact of wild pigs in the United States.

description: The present article was based on the valorization of cocoa husks in feed mills. Our main objective is to test the use of varied proportions of cocoa pod pericarp powder with other raw materials of organic origin in duck rations in order to determine its effects on the growth performance of the animals. Our methodology is based on production of organic feed, chemical analyzes in the laboratory and experimentation. Based on experience, cocoa shell flour has considerable nutritional values. Three experimental batches were used for nine ducklings. The best daily weight growth performance is observed in Lot C at 65 % of cocoa shell flour. The average daily weight gains of this Lot C (5.672 g/d) is very significant compared to the others during the six (06) weeks of experimentation. Ducklings cannot eat pure cocoa shell flour because of its somewhat bitter taste, but they will eat food mixed with this flour. Despite the adaptation of these ducklings during the experiment, none of them died.

description: JWST has recently detected numerous disc galaxies at high-redshifts and there have been observations of cold disc galaxies at z > 4 with ALMA. In the Milky Way, recent studies find metal-poor stars in cold disc orbits, suggesting an ancient disc. We investigated a sample of 565,606 stars from the hybrid-CNN analysis of the Gaia-DR3 RVS stars. The sample contains 8,500 stars with [Fe/H]<-1. For a subset of ~200,000 MSTO and subgiant stars we computed distances and ages using the StarHorse code with a mean precision of 1% and 12%, respectively. First, we confirm the existence of metal-poor stars in thin disc orbits - over 50% are older than 13 Gyr. Second, we report the discovery of the oldest thin disc of the Milky Way(MW), which extends across a wide range of metallicities, from metal-poor to super-solar stars. The metal-poor stars in disc orbits manifest as a readily visible tail of the metallicity distribution. The high-[α/Fe] thick disc exhibits a vertical velocity dispersion of 35 km/s, while the thin disc shows 10 to 15 km/s lower at similar ages. Our old thin disc $σ_{V_z}$ appears similar to those estimated for the high-z disc galaxies. Third, we extend the [Y/Mg] chemical clock to the oldest ages and estimate a slope of -0.038 dex/Gyr. Finally, we confirm our discovery by showing that the splash includes high- and low-[α/Fe] populations that are both old and extends to super-solar [Fe/H]. We find about 6 to 10% of the old thin disc was heated to thick disc orbits with the youngest splashed stars being 9 to 10 Gyrs. We conclude the MW thin disc forms <1 billion years from Big Bang, building up inside-out, preceding earlier estimates by about 4-5 billion years. Considering a massive merger event such as the GSE, a Splash is expected - we find a portion of the old thin disc is heated to thick disc velocities and the Splash extends to super-solar [Fe/H] regimes.

description: This study focuses on analysing the different stages of the elaboration's process of the advice provided by PIs in Australia and Chile. For this study, the term “elaboration” relates to the different stages required to research, collect, construct, and disseminate the PIs recommendations. The objective is to understand which key elements are involved along the process and if these elements can significantly impact the information of the reports. To examine how these elements converge to elaborate reports, this study selected two published studies submitted by the Australian and Chilean Productivity Commissions in 2016 and 2015, respectively. These reports seek to understand how governments deal with the emergence of new technologies in transportation, particularly the emergence of Electric (EVs) and Autonomous Vehicles (AVs) which have become particularly important due to the significance of climate change and carbon footprint has in transportation and other sources of carbon emissions.

description: Using the 3D smoothed particle hydrodynamics code PHANTOM, we investigate the evolution of the orbital properties of massive black hole binaries embedded in massive discs where gravitational instabilities (GIs) triggered by the disc self-gravity are the only source of angular momentum transport. In particular, we investigate the evolution of binaries with different initial eccentricities $e_0=0.05,\,0.5,\,0.8$ and mass ratios $q=0.1,\,0.3,\,0.9$. Our simulations suggest that there might not be a unique value of critical eccentricity. We find initially more eccentric binaries to tend to higher asymptotic eccentricity values than more circular ones. This implies that there is a range of critical eccentricity values, that depends on the initial condition of the system. In particular, we find the width of this range to be narrower for more unequal binaries. We furthermore measure preferential accretion onto our binaries, finding more accretion onto the primary only for mass ratio $q=0.3$ and eccentricity $e=0.8$. We discuss how this might have implications for the amplitude of the gravitational wave background detected by Pulsar Timing Arrays (PTA) experiments. We finally measure the corresponding value of the viscosity parameter $α$ in our simulations and discuss how this depends on the binary properties.

Subjects: subject: Business Administration, Management.

description: This research intends to inform policy discussion on the subject of Aerospace and Defence sector procurement strategies at Industry Canada (IC). Specifically, this research explores procurement strategies in terms of a real option pricing model that move toward a novel use of Industrial and Regional Benefits (IRB) policies in promoting sector-specific, innovation-driven growth. It is further hypothesized that IRB obligations can be better tailored to encourage value adding activities within prime contractors' supply chains (typically small and medium enterprises in this sector). This research focusses on the novel development of a decision support tool using a theory of option pricing for derivatives whose returns fluctuate according to a power law distribution. This tool is shown to provide guidance to assist in adequately rewarding prime contractors who invest in innovative activities while fulfilling their IRB obligations.

description: Waveguide quantum electrodynamics represents a powerful platform to generate entanglement and tailor photonic states. We consider a pair of identical qubits coupled to a parity invariant waveguide in the microwave domain. By working in the one- and two-excitation sectors, we provide a unified view of decay processes and we show the common origin of directional single photon emission and two photon directional bunching. Unveiling the quantum trajectories, we demonstrate that both phenomena are rooted in the selective coupling of orthogonal qubits Bell states with different photon propagation directions. We comment on how to use this mechanism to implement optimized post-selection of Bell states, heralded by the detection of photons on one qubits side.

description: The alien hand syndrome (AHS) is a fascinating movement disorder. Patients with AHS experience one of their limbs as alien, which acts autonomously and performs meaningful movements without being guided by the intention of the patient. Here, we report a case of a 74-years old lady diagnosed with an atypical Parkinson syndrome by possible corticobasal degeneration. The patient stated that she could not control her right hand and that she felt like this hand had her own life. We tested the patient for ownership illusions of the hands and general tactile processing. Results revealed that when blindfolded, the patient recognized touch to her alien hand only if it was presented separated from touch to the other hand (bilateral asynchronous touch). Delivering touch synchronously to both the alien and the healthy hand resulted in failure of recognizing touch to the alien hand (bilateral synchronous touch). Thus, AHS here co-existed with right-sided tactile extinction and is one of only very few cases in which the alien hand was felt on the right side. We discuss the results in the light of recent research on AHS.

description: The monosialoganglioside GM1 is an anionic glycosphingolipid found ubiquitously in the plasma membrane of mammalian cells. Although its exact normal biological function(s) and physical properties are unknown, it is speculated that GM1 may play a role in calcium transport and synaptic transmission in neural tissues. Fourier Transform Infrared (FTIR) spectroscopy was employed to test the model of bovine brain GM1 ganglioside incorporated into perdeuterated dimyristoylphosphatidylcholine (DMPCd54) multilamellar dispersions. The interaction of Ca 2+ ions with the mixed DMPCd54/GM1 bilayers and its effect on the hydrogen bonding at the interfacial region was also investigated. No thermal phase transition was displayed by the GM1 micellar suspensions over the temperature range from 5 to 60°C, even at concentrations of 110 mg/ml. On the other hand, in the mixed DMPCd54 /GM1 multilamellar bilayers, both the acyl chains of GM1 and the perdeuterated hydrocarbon chains of DMPCd54 exhibited a single, cooperative gel to liquid crystalline phase transition, occurring at a higher temperature than in pure DMPCd54 dispersions. This suggests that the ceramide moiety of the glycolipid inserts into the hydrophobic core of the phospholipid bilayer and that the mixed liposomes consisted of a homogeneous mixture of GM1 and DMPCd54 molecules. GM1 had an ordering effect on the mixed bilayers that was further enhanced by the divalent cation C2+. Spectral changes of the amide I and ester carbonyl bands at the interfacial zone indicated a reduced hydrogen bonding of these groups in the mixed liposomal bilayers. Our results also suggested that the ceramide moiety of GM1 inserts into the lipid bilayer of shorter chain symmetric phospholipids and terminates at the bilayer center (i.e., no interdigitation), forcing the carbohydrate headgroup to protrude farther out of the bilayer surface to allow a better binding to Ca2+ ions than DMPCd54. The divalent cation increased the probability of hydrogen bonding at the interfacial region. It is strongly believed that GM1 is involved in the translocation of extracellular signals across the plasma membrane and that the glycolipid affects interfacial hydrogen bonding and local hydrophobicity of the cell surface, which might modulate various surface events such as cell/cell and cell/surface protein interactions.

description: We present encube-a qualitative, quantitative and comparative visualisation and analysis system, with application to high-resolution, immersive three-dimensional environments and desktop displays. encube extends previous comparative visualisation systems by considering: (1) the integration of comparative visualisation and analysis into a unified system; (2) the documentation of the discovery process; and (3) an approach that enables scientists to continue the research process once back at their desktop. Our solution enables tablets, smartphones or laptops to be used as interaction units for manipulating, organising, and querying data. We highlight the modularity of encube, allowing additional functionalities to be included as required. Additionally, our approach supports a high level of collaboration within the physical environment. We show how our implementation of encube operates in a large-scale, hybrid visualisation and supercomputing environment using the CAVE2 at Monash University, and on a local desktop, making it a versatile solution. We discuss how our approach can help accelerate the discovery rate in a variety of research scenarios.

description: We present the second release of the Meta-catalogue of X-Ray detected Clusters of galaxies (hereafter MCXC-II). The MCXC-II has been compiled from publicly available ROSAT All Sky Survey-based (NORAS, REFLEX, BCS, SGP, NEP, MACS, CIZA, RXGCC) and serendipitous (160SD, 400SD, SHARC, WARPS, and EMSS) cluster catalogues. Redshifts were systematically checked and updated if necessary, and additional redshift information (type and origin) added. The X-ray data were standardised to an overdensity of 500 using a new procedure based on the use of the original flux and aperture measurements available in the input catalogues. MCXC-II contains 2221 entries, essentially completing the census of ROSAT cluster detections by including objects from the REFLEX-II and RXGCC surveys, in addition to providing a complete and fully-homogenised sub-catalogue of all published MACS clusters. Duplicate entries from overlaps between the survey areas of the individual input catalogues were carefully handled. For each cluster the MCXC-II provides three identifiers, a redshift, coordinates, membership in the original catalogue, and standardised [0.1-2.4] keV band luminosity $L_{500}$, total mass $M_{500}$, and radius $R_{500}$. Uncertainties on $L_{500}$ were computed from the flux errors in the original catalogues. MCXC-II additionally furnishes information on overlaps between the input catalogues, gives the luminosity and its uncertainty when measurements from different surveys are available, and provides notes on individual objects.
description: 43 pages, 26 figures, accepted for publication in Astronomy & Astrophysics (10/04/2024). A new catalogue is temporarily downloadable via the link from https://www.galaxyclusterdb.eu/m2c/
Does science transcend culture?

Subjects: subject: Anthropology, Cultural.

description: This is a study of whether Science DOES transcend Culture naturally--not whether it CAN do so. That Science can be adopted into any culture is clear from modern history (as in China today). That Science does not automatically develop even when a Culture has reached a high level of technical achievement (as in modern China) or intellectual sophistication (as in ancient Greece) is also clear from history. Evidently Science and Technology are not the same thing, for none of these high Cultures ever succeeded in crossing the threshold into an Industrial Revolution. Yet it did appear in Europe where Technology is not particularly remarkable, but Philosophy is. Research has shown that non-Indo-Europeans are highly inventive and responsible for all basic Technology, but are quite un-philosophical. On the other hand, Indo-Europeans are quite uninventive but philosophically inclined and responsible for all philosophical systems. Neither Philosophy nor Technology alone is capable of producing Science. Only when Philosophy is applied to Technology does Science arise. An examination of the reasons for these circumstances constitutes the subject of this thesis. To the question, Can Science transcend Culture, the answer would be unquestionably, Yes. To the question, Does Science transcend Culture, the answer apparently is NO. Science can transcend Culture but apparently it does not by nature do so. It thus appears to be an activity that is culturally conditioned. The interrelationship between language and thought is explored: evidence show that non-Indo-European languages do not permit or encourage speculation of a philosophical nature, whereas Indo-European languages do. How did this bifurcation come about and what factors tend to preserve it? Did language predetermine thought patterns, or has some mental characteristic, possibly genetically determined, been responsible for the structure of language? The possible relevance of all this in terms of educational methods is considered. By formulating precisely the relationships between Philosophy, Technology, and Science, and by giving attention to the part which the structure of Language plays in these relationships, it is hoped to give some direction to the content of Education needed to train and equip Scientists.
Examining food insecurity among food bank members in Greater Vancouver

description: Background: Few studies have described predictors of severe food insecurity among food bank users. A survey of 77 Vancouver food bank members assessed socio-demographic characteristics, food bank use and household food insecurity (HFI). Fisher’s exact tests explored associations between member characteristics and severe HFI. Results: Participants reported low incomes and 84% relied on social assistance. On average, members used food banks twice per month, 54% were long-term users (>5 years) and 66% reported severe HFI. Neither frequency nor duration of food bank use were significantly associated with severe HFI. This study supports growing evidence that food bank use does not ameliorate severe HFI.
