description: There is a substantial literature on testing for the equality of the cumulative incidence functions associated with one specific cause in a competing risks setting across several populations against specific or all alternatives. In this paper we propose an asymptotically distribution-free test when the alternative is that the incidence functions are linearly ordered, but not equal. The motivation stems from the fact that in many examples such a linear ordering seems reasonable intuitively and is borne out generally from empirical observations. These tests are more powerful when the ordering is justified. We also provide estimators of the incidence functions under this ordering constraint, derive their asymptotic properties for statistical inference purposes, and show improvements over the unrestricted estimators when the order restriction holds.

description: The nature of time has beguiled philosophers for nearly three millennia. There are myriad types of time including cosmological time, biological time, psychological time, physical time, historical time, and even theological time. My brief essay concerns time in physics and I hope that the pragmatism of an experimental physicist might help provide a perspective that is often absent in treatises by contemporary philosophers and physicists. This is especially the case for the notion of the arrow of time. The paradox of the arrow of time arises because the laws of physics are invariably time reversal invariant, in which case we are led to ask what determines the direction of time. Investigations of time's arrow are usually framed in the context of a mathematical formalism where the parameter t represents time, and then proceed to logical analyses of how the direction of time emerges. The implicit assumption is that time is an ontological property of nature. On the other hand, for an empiricist like me, it is absolutely crucial to frame any such discussion in terms of direct human experience and not on a parameter in a mathematical model. This, in short, is the motivation for my essay and I conclude that the paradox of the arrow of time is an artificial problem that needs no resolution.

Motivated Climate Change Denial [Registered Report Stage 1 Protocol]

Subjects: Climate Science

description: Climate change is arguably one of the greatest challenges of our times. Albeit the scientific consensus that human activities caused climate change, a substantial part of the population downplays or denies human responsibilities. In this registered report, we will present causal evidence on a potential explanation for this discrepancy: motivated reasoning. We conduct a tailored survey experiment on a broadly representative sample of 4,000 U.S. adults to provide causal evidence on how motivated cognition shapes beliefs about climate change and influences the demand for slanted information. We further explore the role of motives on environmentally harmful behavior. Our key design idea is to exogenously vary the possibility to behave selfishly at the expense of the climate. Participants that have the opportunity to act selfishly justify their actions by distorting their beliefs and seeking out slanted information. Further, providing participants with an excuse increases the likelihood of selfish and environmentally harmful behavior.

The failure at Colonial can happen to anyone who runs a control system and uses modern technology for the user interface, regardless of the underlying control system. Electric utilities are just as vulnerable as Colonial was.  Understanding Ransomware, how it gets into a system, what it does when it engages, and what you lose if you don’t pay. Ransomware is insidious and hard to stop, a simple firewall is not enough to stop it, nor is a spam filter enough. Ransomware can take many paths into an organization, even a smart phone. Phishing is one of the most common paths into an enterprise. Not all ransomware is restricted to Microsoft platforms, and some can even attack control system platforms. Here are some tips on actively avoiding ransomware, keeping it out of control systems, and finding it before it is too late.

description:
The recent increase in extensively drug-resistant bacterial pathogens and the associated increase of morbidity and mortality demonstrate the immediate need for new antibiotic backbones with novel mechanisms of action. Here, we report the development of the PepSAVI-MS pipeline for bioactive peptide discovery. This highly versatile platform employs mass spectrometry and statistics to identify bioactive peptide targets from complex biological samples. We validate the use of this platform through the successful identification of known bioactive peptides from a botanical species, Viola odorata. Using this pipeline, we have widened the known antimicrobial spectrum for V. odorata cyclotides, including antibacterial activity of cycloviolacin O2 against A. baumannii. We further demonstrate the broad applicability of the platform through the identification of novel anticancer activities for cycloviolacins by their cytotoxicity against ovarian, breast, and prostate cancer cell lines.

description: We discuss an experimental technique to visualize the motion in the bulk of superfluid $^4$He by tracking micron-sized solid hydrogen tracers. The behavior of the tracers is complex since they may be trapped by the quantized vortices while also interacting with the normal fluid via Stokes drag. We discuss the mechanism by which tracers may be trapped by quantized vortices as well as the dependencies on hydrogen volume fraction, temperature, and flow properties. We apply this technique to study the dynamics of a thermal counterflow. Our observations serve as a direct confirmation of the two-fluid model as well as a quantitative test of the normal fluid velocity dependence on the applied heat flux.

description: We show how to construct consistent braneworld models which exhibit late time acceleration. Unlike self-acceleration, which has a de Sitter vacuum state, our models have the standard Minkowski vacuum and accelerate only in the presence of matter, which we dub ``stealth-acceleration''. We use an effective action for the brane which includes an induced gravity term, and allow for an asymmetric set-up. We study the linear stability of flat brane vacua and find the regions of parameter space where the set-up is stable. The 4-dimensional graviton is only quasi-localised in this set-up and as a result gravity is modified at late times. One of the two regions is strongly coupled and the scalar mode is eaten up by an extra symmetry that arises in this limit. Having filtered the well-defined theories we then focus on their cosmology. When the graviton is quasi-localised we find two main examples of acceleration. In each case, we provide an illustrative model and compare it to LambdaCDM.

description: We study inhomogeneities in the distribution of the excursion sets in the Cosmic Microwave Background (CMB) temperature maps obtained by the three years survey of the Wilkinson Microwave Anisotropy Probe (WMAP). At temperature thresholds |T|<90 μK, the distributions of the excursion sets with over 200 pixels are concentrated in two regions, nearly at the antipodes, with galactic coordinates l= 94^\circ.7, b= 34^\circ.4 and l= 279^\circ.8, b= -29^\circ.2. The centers of these two regions drift towards the equator when the temperature threshold is increased. The centers are located close to one of the vectors of \ell =3 multipole. The two patterns of the substructures in the distribution of the excursion sets are mirrored, with χ^2=0.7-1.5. There is no obvious origin of this effect in the noise structure of WMAP, and there is no evidence for a dependence on the galactic cut. Would this effect be cosmological, it could be an indication of an anomalously large component of horizon-size density perturbations, independent of one of the spatial coordinates, and/or of a non-trivial slab-like spatial topology of the Universe.

Reticulipeurus

description: Reticulipeurus (Forcipurellus) species 3
Host. Arborophila javanica (Gmelin, 1789) —chestnut-bellied partridge.
Remarks. We examined a single female, which appears to be most similar to that of R. (F.) formosanus. However, the preantennal head of this female is more broadly rounded, and the shape of the vulval margin (including the shape of the lateral lobes) appears to be different. More specimens, in particular males, are needed to elucidate the identity of the Reticulipeurus from Arborophila javanica. Lipeurus unicolor Piaget, 1880 —described from Arborophila javanica —has been placed in the genus Oxylipeurus by Clay (1938) and followed by Price et al. (2003). However, we regard it as a species of Megalipeurus following Gustafsson et al. (2020b) (see Table 2).

La conservation plus efficace quand les peuples autochtones et les communautés locales sont inclus dans la gouvernance

description: Alors que plusieurs pays se sont déjà engagés en amont de la 15e conférence des Nations Unies à atteindre 30 % d’aires protégées d’ici à 2030, le débat sur la proportion des terres et mers à protéger pour préserver la biodiversité occulte souvent la question de savoir comment et par qui la nature doit être conservée.

Ces questions sont pourtant cruciales pour permettre une conservation efficace de la biodiversité. Cette étude présente une revue systématique de 169 publications examinant comment différentes formes de gouvernance influencent les résultats de la conservation, en accordant une attention particulière au rôle joué par les peuples autochtones et les communautés locales.

L’étude met en avant un contraste frappant entre les résultats d’une conservation contrôlée de l’extérieur et ceux produits par des efforts contrôlés localement. La plupart des cas présentant des résultats positifs à la fois pour le bien-être et la conservation proviennent de cas où les peuples indigènes et les communautés locales jouent un rôle central. C’est le cas, par exemple, lorsque ces communautés ont une influence substantielle sur la prise de décision. En revanche, lorsque les efforts de conservation sont contrôlés par des organisations externes et impliquent des stratégies visant à modifier les pratiques locales, elles tendent à aboutir à une conservation relativement inefficace, tout en produisant des résultats sociaux négatifs.

Une conservation équitable, qui renforce et soutient l’intendance (stewardship) environnementale des peuples autochtones et des communautés locales, représente la principale voie vers une conservation efficace à long terme de la biodiversité, en particulier lorsqu’elle est soutenue par des lois et des politiques plus larges. Cette étude explique en détail comment mettre en œuvre des transitions de gouvernance progressives par le biais de recommandations pour la politique de conservation, avec des implications immédiates pour la réalisation des objectifs de conservation dans le cadre de la Convention des Nations unies sur la diversité biologique.

description: $β$-Ag$_2$Se is a promising material for room temperature thermoelectric applications and magneto-resistive sensors. However, no attention was paid earlier to the hysteresis in the temperature dependence of resistivity ($ρ$($T$)). Here, we show that a broad hysteresis above 35 K is observed not only in $ρ$($T$), but also in other electronic properties such as Hall coefficient ($R_H$($T$)), Seebeck coefficient, thermal conductivity and ultraviolet photoelectron spectra (UPS). We also show that the hysteresis is not associated with a structural transition. The $ρ$($T$) and $R_H$($T$) show that $β$-Ag$_2$Se is semiconducting above 300 K, but metallicity is retained below 300 K. While electronic states are absent in the energy range from the Fermi level ($E_F$) to 0.4 eV below the $E_F$ at 300 K, a distinct Fermi edge is observed in the UPS at 15 K suggesting that the $β$-Ag$_2$Se undergoes an electronic topological transition from a high temperature semiconducting state to a low temperature metallic state. Our study reveals that a constant and moderately high thermoelectric figure of merit ($ZT$) in the range 300-395 K is observed due to the broad semiconductor to metal transition in $β$-Ag$_2$Se.

description: This Master of Design Thesis project focuses on the condition of severe hypoglycemia (low blood sugar) in young adults living with type 1 diabetes by carefully understanding the unique challenges they face in transitioning to adult care. This research surfaces the needs that often get blurred in the transition process and offers a design for an appropriate solution to support the identified issues. Canadian young adults living with type 1 diabetes often find themselves at the risk of hypoglycemia during emerging adulthood. The concept of emerging adulthood has not been considered extensively in managing chronic illness and transition from pediatric to adult care. Yet, this is a critical time when a person may first assume full responsibility for their diabetes self-care while simultaneously facing all the usual challenges young adults face. Additionally, the fear of hypoglycemia is strongest in this group. A review of the literature informs us about previous work done in this field. However, most current interventions are in the form of bulky printed materials. Another critical issue with the development of most recent tools is the absence of user involvement in the creative process leading to unmet user needs. In this project, participatory design methodologies were introduced in a human-centered approach, collaborating with young adults to understand and address the transition process gap. It included actively listening to user narratives and co-creating the solution. The synthesis of primary and secondary research resulted in the designed outcome of a smart wearable device that will work in conjunction with the Continuous glucose monitor (CGM) and alerts the bystander and emergency contacts by turning them into potential lifesavers. It will inform them of a diabetic emergency and guide them through the life-saving instructions. Additionally, it will alert the medical emergency services for prompt assistance if needed. The solution attempts to provide early intervention during emergency and could also alleviate the fear of hypoglycemia in young adults. This in turn will reduce the load on the already burdened healthcare system.

description: This document incorporates the description of the theoretical and practical foundations of my research and studio practice. I have conducted excavations and inquiries about the injustices that occurred in the lower mainland of British Columbia across the 20th-century related to colonialism, racism and gentrification. The historical events that have been studied are mainly regarding the forced removals of Japanese and African Canadians. The research is involved in applying the critical design methodology of Alternative Histories to support communities that have been historically underrepresented. Alternative Histories are a design methodology proposed by British designer James Auger which proposes that it is useful to re-imagine the past in order to re-engineer the present. Through writing Alternative Histories, constructing architectural models, and utilizing rendering and virtual reality technologies, the final thesis project aims to make audiences reconsider the past ideals and losses of Hogan's Alley, a historic Black community in Vancouver that has been erased due to the construction of Georgia Viaduct, a raised highway that connects East Vancouver with Downtown. This project, unexpectedly, contributes to the negotiation between Hogan's Alley Society and the local government on the removal of the Georgia Viaduct and community reconstruction. Ultimately, my research guides the audience to take a historical detour and brings to the surface the problems of colonialism, racism, and gentrification in Vancouver to attract social attention. Through the research, I aim to ask what the capabilities of Alternative Histories are as a position to unveil historical wrongs and institutional discrimination. In conclusion, the research finds that Auger’s alternative histories are actually useful in contemporary design projects.

Apart from demonstrating the efficacy of the approach via curved Casimirs, this shows that this method applies both in regular and in singular infinitesimal character, and also that it can be used to construct standard as well as non--standard operators. The examples treated include conformally invariant operators with leading term, in one case, a square of the Laplacian, and in another case, a cube of the Laplacian.

Cryptophagus laticollis is newly recorded in Nova Scotia and eastern North America (Fig. 2). It is an adventive Palaearctic species, previously recorded in North America from the west coast in British Columbia, Alberta, California, Oregon, and Washington (Woodroffe and Coombs 1961; Bousquet 1991). It is a cosmopolitan species found throughout the Palaearctic in Europe, North Africa, and Asia, and in Australia, sub-Saharan Africa, and the Orient (Johnson et al. 2007). It is found on stored products and in vegetable refuse (Woodroffe and Coombs 1961). The small conical eyes of C. laticollis distinguish this species from the similar Cryptophagus setulosus (Woodroffe and Coombs 1961).

Bishop, red spruce (45 years), FIT (1, NSMC); Panuke Lake, 29 July-13 Aug, 1997, D.J. Bishop, red spruce (45 years), FIT (1, NSMC). Cryptophagus mainensis is newly recorded in insular Newfoundland, Nova Scotia, and Canada as a whole (Fig. 3). This is a Nearctic species previously known only from Maine, New Hampshire, New York, and Ohio (Woodroffe and Coombs 1961; Chandler 2001). In Nova Scotia specimens were collected in red spruce (Picea rubens Sarg., Pinaceae) and mixed eastern hemlock (Tsuga canadensis (L.) Carr., Pinaceae) and red spruce forests varying in age from old growth (120+ years) to 45 years. This is the first habitat information about this species. It is a very distinctive species on account of its small size (1.5–1.7 mm.) and very large pronotal callosities which subtend 1/3 of the lateral margin of the pronotum.

description: We propose to combine the advantages of graphene, such as easy tunability and long coherence times, with Josephson physics to manufacture qubits. If these qubits are built around a 0 and $π$ junction they can be controlled by an external flux. Alternatively, a d-wave Josephson junction can itself be tuned via a gate voltage to create superpositions between macroscopically degenerate states. We show that ferromagnets are not required for realizing $π$ junction in graphene, thus considerably simplifying its physical implementation. We demonstrate how one qubit gates, such as arbitrary phase rotations and the exchange gate, can be implemented.

description: This paper is about optimal estimation of the additive components of a nonparametric, additive isotone regression model. It is shown that asymptotically up to first order, each additive component can be estimated as well as it could be by a least squares estimator if the other components were known. The algorithm for the calculation of the estimator uses backfitting. Convergence of the algorithm is shown. Finite sample properties are also compared through simulation experiments.

D1.1 Comprehensive overview of the project
Creators: name: SuPreAM Partners
Publisher: name: Zenodo
Year: 2024

description: This deliverable addresses the complex landscape surrounding the introduction of steel additive manufactured components in industrial and aerospace applications. It navigates through studies, research findings and potential impacts, highlighting the evolving dynamics of predictive models on surface finishing operations and the challenges associated with the final surface integrity of functional components.

Additive Manufacturing (AM) is widely used in the manufacture and repair of metallic parts. The process provides a means for components of intricate geometry to be manufactured using a laser beam with material being delivered into the laser path on the desired substrate. Parts produced by AM commonly present poor surface quality and wide dimensional accuracy; thus, machining processes are required to obtain optimal surface integrity. Surface properties have an enormous influence on features such as dimensional accuracy, friction coefficient and wear, thermal and electric resistance, fatigue limit, corrosion, appearance and cost. Hence, optimum surface integrity is crucial for the proper functionality of machined workpieces.

SuPreAM project aims at optimizing surface integrity of AMed + machined steel components to reduce manufacturing expenditures at the steel industrial sector through the minimization of scrap and avoidance of re-processing loops. Predictive models of finishing operations will be developed considering the influence of AM technology and steel grades, machining operations, strategies and process parameters on machinability and surface properties of AMed components, enabling the identification of main variables affecting surface integrity. Particle Finite Element Method will be developed for the first time to study of AMed machined steels and AM parameters will be adjusted for a new quality of lean maraging steel.

Two representative case studies have been selected. In both cases, components are real in-use parts proposed for improvement with requirements very closely related to surface quality: 1) a plastic injection mould, surface finish is crucial to ensure quality of moulded parts and mould behaviour (thermal fatigue and wear resistance); 2) a structural component for aerospace application, which requires fatigue resistance. Demonstrators of both case-studies will be produced and used for model validation and comparison with conventional steels.

description: We present a general methodology for performing statistical inference on the components of a real-valued matrix parameter for which rows and columns are subject to order restrictions. The proposed estimation procedure is based on an iterative algorithm developed by Dykstra and Robertson (1982) for simple order restriction on rows and columns of a matrix. For any order restrictions on rows and columns of a matrix, sufficient conditions are derived for the algorithm to converge in a single application of row and column operations. The new algorithm is applicable to a broad collection of order restrictions. In practice, it is easy to design a study such that the sufficient conditions derived in this paper are satisfied. For instance, the sufficient conditions are satisfied in a balanced design. Using the estimation procedure developed in this article, a bootstrap test for order restrictions on rows and columns of a matrix is proposed. Computer simulations for ordinal data were performed to compare the proposed test with some existing test procedures in terms of size and power. The new methodology is illustrated by applying it to a set of ordinal data obtained from a toxicological study.

Safety in human-multi robot collaborative scenarios: a trajectory scaling approach

description: In this paper, a strategy to handle the human safety in a multi-robot scenario is devised. In the presented framework, it is foreseen that robots are in charge of performing any cooperative manipulation task which is parameterized by a proper task function. The devised architecture answers to the increasing demand of strict cooperation between humans and robots, since it equips a general multi-robot cell with the feature of making robots and human working together. The human safety is properly handled by defining a safety index which depends both on the relative position and velocity of the human operator and robots. Then, the multi-robot task trajectory is properly scaled in order to ensure that the human safety never falls below a given threshold which can be set in worst conditions according to a minimum allowed distance. Simulations results are presented in order to prove the effectiveness of the approach.

description: We study the dynamics of quantized superfluid vortices on axisymmetric compact surfaces with no holes, where the total vortex charge must vanish and the condition of irrotational flow forbids distributed vorticity. A conformal transformation from the surface to the complex plane allows us to use familiar formalism to describe the motion of the quantized vortices and to find the total energy. The simplest case is a vortex dipole with unit vortex charges on an axisymmetric ellipsoid. We study two special symmetric vortex-dipole configurations along with a general asymmetric one.

Effects of advance organizers on immediate and delayed recall of oral learning in grades four and seven
Creators: name: Fletcher, Marjorie Jane Shortt
Publisher: name: University of British Columbia
Year: 2010

description: The goal of this study was to explore the use of advance organizers in an oral learning situation at two elementary school grade levels. It had four main purposes: 1) to determine whether or not advance organizers would facilitate retention in oral learning; 2) to determine if one particular type of organizer would facilitate more than another; 3) to discover whether there were grade differences in retention from an oral lesson; and 4) to determine if there would be differences in the occasion of recall (immediate or delayed). Students in grade four and seven were randomly assigned to one of four treatment groups: no organizer, outline organizer, prequestion organizer and visual organizer. Each of the treatment groups employing an advance organizer received the same abstract comparative advance organizer followed by an organizer unique to their treatment. The no organizer treatment received an unrelated listening task in place of the organizers. After an oral learning task of connected discourse, presented on audio tape, all subjects received one of two versions of a sentence completion test based on the listening task. This was the measure of immediate recall. One week later they were administered the second parallel version of the same test as the delayed recall measure. The results indicated no facilitative effects for advance organizers. There were also no statistically significant interactions between the treatment group and grade level or occasion of recall. Grade level and occasion both showed main effects. After reexamining the stimuli and recall measures utilized in the study, it was decided that the absence of the expected facilitating effect for advance organizers and of any interactions with them was probably due to poorly constructed stimuli and inappropriate recall measures combined with some administration difficulties. The grade level main effect was attributed primarily to developmental memory capacities while the main effect of occasion might be accounted for by depth of processing differences.

description: We present a new method for constructing equilibrium phase models for stellar systems, which we call the iterative method. It relies on constrained, or guided evolution, so that the equilibrium solution has a number of desired parameters and/or constraints. This method is very powerful, to a large extent due to its simplicity. It can be used for mass distributions with an arbitrary geometry and a large variety of kinematical constraints. We present several examples illustrating it. Applications of this method include the creation of initial conditions for N-body simulations and the modelling of galaxies from their photometric and kinematic observations.
