description: This paper presents a mathematical model that uses a British cone to predict the soil moisture-penetration relationship. This relationship is nonlinear for non-bentonite bearing soil and can be modelled using a sigmoidal mathematical function. The developed mathematical model gives a unique opportunity for computing and predicting the fall cone penetration of the soil even at a very low moisture content, at which, due to practical limitations, it is impossible to determine the soil penetration. The mathematical model was found to fit the moisture-penetration data reasonably well. Based on the data presented in this paper, both the liquid limit and plastic limit can be determined from the extended liquid limit flow curve by determining the plastic limit at a 1.2 mm penetration value. The computed plastic limit at a 1.2 mm penetration value was found to be in close agreement with the measured plastic limit.

description: In order to explore repulsive Casimir/van der Waals forces between solid materials with liquid as the intervening medium, we analyze dielectric data for a wide range of materials as for example PTFE, polystyrene, silica and more than twenty liquids. Although significant variation in the dielectric data from different sources exist, we provide a scheme based on measured static dielectric constants, refractive indices, and applying Kramers Kronig (KK) consistency to dielectric data to create accurate dielectric functions at imaginary frequencies. The latter is necessary for more accurate force calculations via the Lifshitz theory allowing reliable predictions of repulsive Casimir forces.

description: Optical Faraday rotation is one of the most direct and practically important manifestations of magnetically broken time-reversal symmetry. The rotation angle is proportional to the distance traveled by the light, and up to now sizeable effects were observed only in macroscopically thick samples and in two-dimensional electron gases with effective thicknesses of several nanometers. Here we demonstrate that a single atomic layer of carbon - graphene - turns the polarization by several degrees in modest magnetic fields. The rotation is found to be strongly enhanced by resonances originating from the cyclotron effect in the classical regime and the inter-Landau-level transitions in the quantum regime. Combined with the possibility of ambipolar doping, this opens pathways to use graphene in fast tunable ultrathin infrared magneto-optical devices.

description: To characterize the magnetic field structure of the outflow and core region within a prototypical high-mass star-forming region, we analyzed polarized CO(3-2) - for the first time observed with the Submillimeter Array -- as well as 880mum submm continuum emission from the high-mass outflow/disk system IRAS18089-1732. Both emission features with polarization degrees at a few percent level indicate that the magnetic field structure is largely aligned with the outflow/jet orientation from the small core scales to the larger outflow scales. Although quantitative estimates are crude, the analysis indicates that turbulent energy dominates over magnetic energy. The data also suggest a magnetic field strength increase from the lower-density envelope to the higher-density core.

description: Observations and theory both suggest that star clusters form sub-virial (cool) with highly sub-structured distributions. We perform a large ensemble of N-body simulations of moderate-sized (N=1000) cool, fractal clusters to investigate their early dynamical evolution. We find that cool, clumpy clusters dynamically mass segregate on a short timescale, that Trapezium-like massive higher-order multiples are commonly formed, and that massive stars are often ejected from clusters with velocities > 10 km/s (c.f. the average escape velocity of 2.5 km/s). The properties of clusters also change rapidly on very short timescales. Young clusters may also undergo core collapse events, in which a dense core containing massive stars is hardened due to energy losses to a halo of lower-mass stars. Such events can blow young clusters apart with no need for gas expulsion. The warmer and less substructured a cluster is initially, the less extreme its evolution.

Psychological distress in North America during COVID-19 : the role of pandemic-related stressors
Creators: name: Zheng, Jason
Publisher: name: University of British Columbia
Year: 2021

description: The COVID-19 pandemic has wreaked havoc on lives around the globe. In addition to the primary threat of infection, widespread secondary stressors associated with the pandemic have included social isolation, financial insecurity, resource scarcity, and occupational difficulties. The current study examined the impact of these disruptions on psychological distress during the initial adjustment phase to the pandemic in North America. A sample of 2463 residents of the US and Canada completed both baseline and follow-up surveys across several weeks between March and May 2020. Those participants perceiving stress related to higher levels of personal threat to health and to the well-being of family members at baseline reported higher levels of depressive symptoms at follow-up, even after controlling for baseline depressive symptoms. In addition, pandemic-related secondary stressors (social isolation, financial insecurity, occupational difficulty, and resource scarcity) were all independently associated with depressive symptoms at follow-up, controlling for both baseline depression and perceived health threats. The results were robust and held up after controlling for demographic factors. Women, young adults, and those who reported lower income were all at higher risk for subsequent depressive symptoms. Findings from the present study can help to identify key groups at risk for mental health problems during the pandemic and indicate actionable areas for targeted intervention.

description: We obtain the exact asymptotic result for the disorder-averaged probability distribution function for a random walk in a biased Sinai model and show that it is characterized by a creeping behavior of the displacement moments with time, ~ t^{μn} where μis dimensionless mean drift. We employ a method originated in quantum diffusion which is based on the exact mapping of the problem to an imaginary-time Schr\"{odinger} equation. For nonzero drift such an equation has an isolated lowest eigenvalue separated by a gap from quasi-continuous excited states, and the eigenstate corresponding to the former governs the long-time asymptotic behavior.

Massive star formation in Wolf-Rayet galaxies. III: Analysis of the O and WR populations

description: (Abridged) We perform a comprehensive multiwavelength analysis of a sample of 20 starburst galaxies that show the presence of a substantial population of Wolf-Rayet (WR) stars. In this paper we present the analysis of the O and WR star populations. We study the spatial localization of the WR-rich clusters via the detection of the blue WR bump (broad He II 4686) and the red WR bump (broad C IV 5808). We perform a detailed fitting of the nebular and broad emission lines within these broad features and derive the numbers of WN, WC and O stars using (i) the standard assumption of constant WR luminosities and (ii) considering metallicity-dependent WR luminosities. We then compare our results with the predictions given by evolutionary synthesis models and with previous empirical results. Aperture effects and the exact positioning of the slit onto the WR-rich bursts play a fundamental role in their detection. As expected, the total number of WR stars increases with increasing metallicity, but objects with 12+log(O/H)<8.2 show a rather constant WR/(WR+O) ratio. The computed WCE/WNL ratios are different than those empirically found in nearby star-forming galaxies, indicating that the observed galaxies are experiencing a strong and very short burst. Considering metallicity-dependent WR luminosities, our data agree with a Salpeter-like IMF in all regimes. We consider that the contribution of the WCE stars is not negligible at low metallicities. Although available models reproduce fairly well the WR properties at high metallicities, new evolutionary synthesis models for young starbursts including all involved parameters (age, metallicity, star-formation history, IMF and WR stars properties such as metallicity-dependent WR luminosities, stellar rotation and the WR binnary channel) are absolutely needed to perform an appropriate comparison with the observational data.

'It Has to Go Down A Little, In Order to Go Around'- Following Feynman on the Gyroscope

Year: 2010
Subjects: subject: Popular Physics (physics.pop-ph)

description: In this paper we show that with the help of accessible, teaching quality equipment, some interesting details of the motion of a gyroscope, typically overlooked in introductory courses, can be measured and compared to theory. We begin by deriving a simple relation between the asymptotic dip angle of a gyroscope released from rest and its precession velocity. We then describe an experiment which measures these parameters. The data gives excellent agreement with the model. The idea for this project was suggested by the discussion of gyroscopic motion in The Feynman Lectures on Physics. Feynman's conclusion (stated in colloquial terms and quoted in the title) is confirmed and, in addition, conservation of angular momentum, which underlies this effect, is quantitatively demonstrated.

Then $f(\mathbb R^2)$ is a convex domain and $f$ maps $\mathbb R^2$ onto $f(\mathbb R^2)$ homeomorhically.} Here ${\rm curl\,}f(x)$ stands for the curl of $f$ at $x\in\mathbb R^2$. This article is an overview of analogues of this theorem, its generalizations and applications in the theory of surfaces, theory of functions, as well as in the study of the Jacobian conjecture and global asymptotic stability of dynamical systems.

description: Among topics of opinion formation it is of interest to observe the characteristics of networks with a priori distinct communities. As an illustration, we report on the citation network(s) unfolded in the recent decades through web available works belonging to selected members of the Neocreationist and Intelligent Design Proponents (IDP) and the Darwinian Evolution Defenders (DED) communities. An adjacency matrix of tagged nodes is first constructed; it is not symmetric. A generalization of considerations pertaining to the case of networks with biased links, directed or undirected, is thus presented. The main characteristic coefficients describing the structure of such partially directed networks with tagged nodes are outlined. The structural features are discussed searching for statistical aspects, equivalence or not of subnetworks through the degree distributions, each network assortativity, the global and local clustering coefficients and the Average Overlap Indices. The various closed and open triangles made from nodes, moreover distinguishing the community, are especially listed to calculate the clustering characteristics. The distribution of elements in the rectangular submatrices are specially examined since they represent inter-community connexions. The emphasis being on distinguishing the number of vertices belonging to a given community. Using such informations one can distinguish between opinion leaders, followers and main rivals and briefly interpret their relationships through psychological-like conditions intrinsic to behavior rules in either community. Considerations on other controversy cases with similar social constraints are outlined, as well as suggestions on further, more general, work deduced from our observations on such networks.

description: In the given work, selectivity of the action of amino acids on the current through ASIC1a channels was tested. The work was carried out on transfected CHO cells. Current recordings were obtained using patch clamp in whole-cell mode at a membrane potential of â80 mV. It was shown that 20 L-amino acids have no effect on the current through ASIC2a channels; 12 L-amino acids have no effect on the current through ASIC3 channels. Accordingly, it is concluded that the action of amino acids on ASIC1a channels are selective.

description: We consider a topological quantum mechanics described by a phase space path integral and study the 1-dimensional analog for the path integral representation of the Kontsevich formula. We see that the naive bosonic integral possesses divergences, that it is even naively non-invariant and thus is ill-defined. We then consider a super-extension of the theory which eliminates the divergences and makes the theory naively invariant. This super-extension is equivalent to the correct choice of measure and was discussed in the literature. We then investigate the behavior of this extended theory under diffeomorphisms of the extended phase space and despite of its naive invariance find out that the theory possesses anomaly under nonlinear diffeomorphisms. We localize the origin of the anomaly and calculate the lowest nontrivial anomalous contribution.

description: We define a perfect coloring of a graph $G$ as a proper coloring of $G$ such that every connected induced subgraph $H$ of $G$ uses exactly $ω(H)$ many colors where $ω(H)$ is the clique number of $H$. A graph is perfectly colorable if it admits a perfect coloring. We show that the class of perfectly colorable graphs is exactly the class of perfect paw-free graphs. It follows that perfectly colorable graphs can be recognized and colored in linear time.

Flexibility Assessment
FlexTool
Planning

description: The power system flexibility assessment and application using the IRENA flexTool involves a comprehensive evaluation of the flexibility potential of a power system. The flexTool is an analytical tool developed by the International Renewable Energy Agency (IRENA) that provides a systematic approach to assess the flexibility of a power system in terms of its ability to balance electricity supply and demand. The flexTool considers various parameters that affect the flexibility of a power system, such as the demand profile, generation mix, storage capacity, and grid infrastructure. It also accounts for the variability and uncertainty of renewable energy sources, which are increasingly integrated into power systems worldwide. The assessment carried out using the flexTool can help identify the flexibility measures that can be implemented to improve the resilience and reliability of the power system. These measures may include energy storage, demand-side management, interconnection with other power systems, and flexible generation. The application of the flexTool involves analyzing the data obtained from the assessment to develop a flexible and optimized power system plan. The plan should aim to achieve a balance between electricity supply and demand, ensure grid stability and security, and promote the integration of renewable energy sources. Overall, the power system flexibility assessment and application using the IRENA flexTool is a valuable tool for power system planners and operators to ensure a resilient and sustainable power system that meets the evolving energy needs of society.
Decolonizing conservation? The politics of recognition in Indigenous and Community Conserved Areas (ICCAs)
Creators: name: Sachs, Cora
Publisher: name: University of British Columbia
Year: 2021

description: This thesis explores the role of Indigenous and Community Conserved Areas (ICCAs) in promoting decolonization. By drawing on critical Indigenous political theorists and decolonial scholars, I assess how recognition-centered approaches that maintain structural and subjective dimensions of colonial power dynamics within conservation may limit the potential of ICCAs to support decolonialization for Indigenous peoples and local communities. I situate ICCAs within mainstream biodiversity conservation practices, including their histories of enclosure of Indigenous and customarily held lands through protected areas, the displacement, criminalization, and oppression of Indigenous peoples and local communities associated with many protected areas, and current conservation-associated threats to life and sovereignty for Indigenous peoples. Based a critical literature analysis of ICCAs case studies, I find that the State and institutional maintenance of power renders the decolonizing potential severely limited by a politics of recognition. This mostly results from forms of recognition which restrict access to territory or livelihood practices and limit sovereignty by withholding certain rights. Yet, I still argue that ICCAs can offer significant benefits for Indigenous peoples and local communities to practice territorialization and reclaim sovereignty to defend their lands, waters, and resources. Even within recognition-centric approaches, Indigenous peoples and local communities can still realize some critical collective and self-recognition objectives and actively resist colonial encroachment while creating resurgent Indigenous alternatives, transcending a politics of recognition. This is made possible through reterritorialization and acts of everyday decolonization, grounding normativity, revitalizing alternative political economies, and embodying ontological decolonization.

description: We discuss a general mean field plus random phase approximation (RPA) for describing composite systems at zero and finite temperature. We analyze in particular its implementation in finite systems invariant under translations, where for uniform mean fields it requires just the solution of simple local-type RPA equations. As test and application, we use the method for evaluating the entanglement between two spins in cyclic spin 1/2 chains with both long and short range anisotropic XY-type couplings in a uniform transverse magnetic field. The approach is shown to provide an accurate analytic description of the concurrence for strong fields, for any coupling range, pair separation or chain size, where it predicts an entanglement range which can be at most twice that of interaction. It also correctly predicts the existence of a separability field together with full entanglement range in its vicinity. The general accuracy of the approach improves as the range of the interaction increases.

description: (Abridged) We performed a multiwavelength analysis of a sample of starburst galaxies that show the presence of a substantial population of very young massive (WR) stars. Here we present the global analysis of the derived photometric and chemical properties. We compare optical/NIR colours and the physical properties (reddening coefficient, equivalent widths of the emission and underlying absorption lines, ionization degree, electron density, and electron temperature) and chemical properties with previous observations and galaxy evolution models. Attending to their absolute B-magnitude many of them are not dwarf galaxies, but they should be during their quiescent phase. We found that both C(Hb) and Wabs increase with increasing metallicity. We detected a high N/O ratio in objects showing strong WR features. The ejecta of the WR stars may be the origin of the N enrichment in these galaxies. We compared the abundances provided by the direct method with those obtained using empirical calibrations, finding that (i) the Pilyugin method is the best suitable empirical calibration, (ii) the relations between the oxygen abundance and the N2 or the O3N2 parameters provided by Pettini & Pagel (2004) give acceptable results for objects with 12+log(O/H)>8.0, and (iii) the results provided by empirical calibrations based on photoionization models are systematically 0.2-0.3 dex higher than the values derived from the direct method. The O and N abundances and the N/O ratios are related to the optical/NIR luminosity; the dispersion is consequence of the differences in the star-formation histories. Galaxies with redder colours tend to have higher oxygen and nitrogen abundances. Our detailed analysis is fundamental to understand the nature of galaxies showing strong starbursts, as well as to know their star formation history and the relationships with the environment.

description: We investigate the possibility of the acoustic superresonance phenomenon (analog to the superradiance in black hole physics), i.e., the amplification of a sound wave by reflection from the ergoregion of a rotating acoustic black hole with Lorentz symmetry breaking. For rotating black holes the effect of superradiance corresponds to the situation where the incident waves has reflection coefficient greater than one, and energy is extracted from them. For an acoustic Kerr-like black hole its rate of loss of mass is affected by the Lorentz symmetry breaking. We also have shown that for suitable values of the Lorentz violating parameter a wider spectrum of particle wave function can be scattered with increased amplitude by the acoustic black hole.

description: We present the discovery of photometric variations in the carbon-dominated atmosphere (hot DQ) white dwarf star SDSS J133710.19-002643.6. We find evidence for two low-amplitude, harmonically-related periodicities at 169 s and 339 s, making it the fastest and smallest amplitude of the four known hot DQ variables and the only variable whose spectrum suggests the presence of hydrogen. The star's fundamental and harmonic amplitudes are roughly equal, and its pulse shape is similar to the other two members of the class with detected harmonics. Like the other variables, it appears relatively stable in frequency and amplitude.

description: La mia ricerca ha un doppio scopo: conoscere i servizi presenti sul nostro territorio che operano nei confronti di bambini vittime di conflitti famigliari e, grazie alla letteratura, tutte le informazioni riguardanti il conflitto stesso. Mentre, in termini di competenza, venire a conoscenza di possibili attività, consigli, modi di lavorare e su quali valori inquadrare la relazione con questi bambini. Mi sono focalizzata sul possibile metodo e stile di insegnamento da applicare, su quali elementi porre l’attenzione e sulle possibili conseguenze, dovute al conflitto famigliare, che il bambino potrebbe manifestare in classe a contatto con i suoi coetanei. Attraverso le diverse interviste e le letture ho raccolto molti spunti, riflessioni e consigli che mi hanno permesso di capire meglio il conflitto e di stilare diversi approcci utili da investire: - instaurare una relazione fondata sul senso di fiducia e di rispetto reciproco. Il docente deve porsi in modo accogliente, attuando un’accurata osservazione e un ascolto attivo nei confronti del bambino. L’osservazione deve individuare possibili situazioni di disagio che lo colpiscono. È sempre importante considerare ogni situazione a sé, senza mai tirare conclusioni affrettate; - la relazione deve focalizzarsi sulla sincerità da parte del docente, non deve creare false speranze al minore; - la relazione conflittuale prevede un ciclo di violenza composto di quattro fasi in cui a essa seguono momenti più gioiosi in cui sembra che il conflitto non abbia importanza.

Rapid determination of viable but non-culturable Campylobacter jejuni in agri-food products by loop-mediated isothermal amplification coupling propidium monoazide treatment
Creators: name: Petersen, Marlen Wilhelmine
Publisher: name: University of British Columbia
Year: 2021

description: Campylobacter is the leading cause of foodborne human diarrhea in Canada and worldwide. This microbe in the viable but non-culturable (VBNC) state can evade the detection by routinely used culture-based methods, remain viable for extended periods of time, resume their metabolic activity and virulence leading to infections and diseases, and subsequently pose a severe concern to public health, food safety and the economy. In this study, an assay combining loop-mediated isothermal amplification (LAMP) and propidium monoazide (PMA) treatment was developed to detect and quantify VBNC C. jejuni. PMA-qLAMP targeting the hipO gene showed 100% specificity to C. jejuni. The limit of detection was determined to be 8.77×10² CFU/mL in pure bacterial culture with good quantitative capacity ranging from 8.77×10² CFU/mL to 8.77×10⁷ CFU/mL. C. jejuni was induced into the VBNC state by incubation in 7% (w/v) NaCl over 48 h. VBNC C. jejuni cells were determined by PMA-qLAMP coupled with the plating assay and spiked into three agri-foods. The limits of detection of PMA-qLAMP were 1.58×10² CFU/mL, 3.78×10² CFU/g and 4.33×10² CFU/g in milk, chicken breast meat and romaine lettuce, respectively. PMA-qLAMP demonstrated a rapid (from 25 to 40 min), specific (100% inclusivity and 100% exclusivity), sensitive (1.58×10² - 8.77×10² CFU/mL) and quantitative (R² of 0.9937–0.9999) detection of VBNC C. jejuni in pure bacterial culture, chicken meat, milk, and lettuce. Considering the rising Campylobacter infections worldwide and serious concerns of VBNC bacteria, this detection method has extensive potential to be applied in the agri-food industry so as to reduce the burden of C. jejuni infections to the public health and economy.

description: We examine a new mechanism of $e^+e^-$ pair production in $NN$ collisions associated with the $NN$-decoupled dibaryon $d^\star_1$(1956) formation in the process $NN \to γ^\star d^\star_1$, where $γ^\star$ is the virtual photon which converts into a $e^+e^-$ pair. It is shown that a substantial excess of dielectron yields from $Ca+Ca$ and $C+C$ collisions at 1 GeV/A in the dielectron mass spectra in the region from 0.2 to 0.5 GeV/$c^2$ measured by the \textit{DLS Collaboration} as compared with calculated ones can be attributed to the contribution of this mechanism. A simple means for verification of the existence of such a mechanism is proposed.

description: Future Extremely Large Telescopes will adopt segmented primary mirrors with several hundreds of segments. Cophasing of the segments together is essential to reach high wavefront quality. The phasing sensor must be able to maintain very high phasing accuracy during the observations, while being able to phase segments dephased by several micrometers. The Zernike phase contrast sensor has been demonstrated on-sky at the Very Large Telescope. We present the multi-wavelength scheme that has been implemented to extend the capture range from \pmlambda/2 on the wavefront to many micrometers, demonstrating that it is successful at phasing mirrors with piston errors up to \pm4.0 micron on the wavefront. We discuss the results at different levels and conclude with a phasing strategy for a future Extremely Large Telescope.
