description: We present the statistical-mechanical theory of semiflexible polymers based on the connection between the Kratky-Porod model and the quantum rigid rotator in an external homogeneous field, and treatment of the latter using the quantum mechanical propagator method. The expressions and relations existing for flexible polymers can be generalized to semiflexible ones, if one replaces the Fourier-Laplace transform of the end-to-end polymer distance, $1/(k^{2}/3+p)$, through the matrix $\tilde{P}(k,p)=(I+ikDM)^{-1}D$, where $D$ and $M$ are related to the spectrum of the quantum rigid rotator, and considers an appropriate matrix element of the expression under consideration. The present work provides also the framework to study polymers in external fields, and problems including the tangents of semiflexible polymers. We study the structure factor of the polymer, the transversal fluctuations of a free end of the polymer with fixed tangent of another end, and the localization of a semiflexible polymer onto an interface. We obtain the partition function of a semiflexible polymer in half space with Dirichlet boundary condition in terms of the end-to-end distribution function of the free semiflexible polymer, study the behaviour of a semiflexible polymer in the vicinity of a surface, and adsorption onto a surface.

description: In previous papers we have presented many purely bosonic solutions of Generalized Supergravity Equations obtained by Poisson-Lie T-duality and plurality of flat and Bianchi cosmologies. In this paper we focus on their compactifications and identify solutions that can be interpreted as T-folds. To recognize T-folds we adopt the language of Double Field Theory and discuss how Poisson-Lie T-duality/plurality fits into this framework. As a special case we confirm that all non-Abelian T-duals can be compactified as T-folds.

ALPACA : A Phenomenological Approach to Decision Making for Outdoor Educators
Creators: name: Ladner, Christopher
Publisher: name: The University of British Columbia
Year: 2021

description: This conceptual analysis researched what an outdoor educator needed from a decision making model. Current outdoor decision making models have been borrowed from other disciplines and rarely encompassed all an outdoor educator required for creating optimal decisions in their unique environments. This analysis was done through a review of the literature, narrative inquiries in the literature, communications with ten outdoor education experts, my personal reflections on thirty years of teaching outdoor programs, plus a framework called the States of Matter Analysis (SOMA). SOMA applied the physical characteristics of the four states of matter (solid, liquid, gas, and plasma) and made analogies to help define, create meaning, judge and value, and seek inspiration from the decision making components. The six components for an appropriate, applicable, and authentic decision model for outdoor educators emerged as: assensement (assessing using the senses), leadership, place, avoidance of hazards, communication, and action. These components became a decision making model with the acrostic mnemonic of ALPACA. ALPACA was divided into perception, processes, and performance reflecting the three stages of contemporary decision models (Endsley, 1997; Klein, 1993). Perception leading to situational awareness was identified in decision models used in naturalistic environments, yet no model prescribed why or how a decision maker perceived phenomenon. This project proposed that a phenomenological approach to understanding how sensory data was cognitively processed, with the intentions of those cognitions, and the affordances of phenomena, were instrumental for attaining optimal situational awareness. The processes of leadership, place, avoidance, and communication were initially suggested in a British Canoe Union (2006) model and were described and expanded. Performance strategies authentic to an outdoor educator’s context were noticeably lacking in existing outdoor decision models. The research found the Cynefin framework (Snowden & Kurtz, 2003), from outside the outdoor literature, was determined to be the most appropriate and applicable decision model for outdoor educators. The ALPACA decision model’s six components were designed as a tool for training novice outdoor educators for holistic and pragmatic decision making using a phenomenological approach.

An empirical criterion to classify T Tauri stars and substellar analogs using low-resolution optical spectroscopy

description: We have compiled and studied photometric and spectroscopic data published in the literature of several star forming regions and young open clusters (Orion, Taurus, IC348, Sco-Cen Complex, Chamaeleon I, TW Hya association, sigma Orionis cluster, IC2391, alpha Per cluster and the Pleiades). Our goal was to seek the definition of a simple empirical criterion to classify stars or brown dwarfs which are accreting matter from a disk on the sole basis of low-resolution optical spectroscopic data. We show that using Halpha equivalent widths and spectral types we can statistically classify very young stars and brown dwarfs as classical T Tauri stars and substellar analogs. As a boundary between accreting and non accreting objects, we use the saturation limit of chromospheric activity at Log L(Halpha)/L(bol)=-3.3 (determined in the open clusters). We discuss the uncertainties in the classification scheme due to the occurrence of flares. We have used this spectroscopic empirical criterion to classify objects found in the literature, and we compute the fraction of accreting objects in several star forming regions. The fraction of accreting objects appears to decrease from about 50% to about 5% from 1 Myr to 10 Myr for both stars and brown dwarfs.

Orbital ordering is favored by the on site repulsion at the Fe ions. We obtain a rich phase diagram, including ferri- and antiferromagnetic phases, which can, in turn, be metallic or insulating, depending on the existence of orbital order.

description: A new forecasting strategy for stochastic systems is introduced. It is inspired by the concept of anticipated synchronization between pairs of chaotic oscillators, recently developed in the area of Dynamical Systems, and by the earthquake forecasting algorithms in which different pattern recognition functions are used for identifying seismic premonitory phenomena. In the new strategy, copies (clones) of the original system (the master) are defined, and they are driven using rules that tend to synchronize them with the master dynamics. The observation of definite patterns in the state of the clones is the signal for connecting an alarm in the original system that efficiently marks the impending occurrence of a catastrophic event. The power of this method is quantitatively illustrated by forecasting the occurrence of characteristic earthquakes in the so-called Minimalist Model.

description: Hypericin can be found in nature in Hypericum perforatum (St. John's Wort) and has become subject of intense biochemical research. Studies report of antidepressive, antineoplastic, antitumor and antiviral activity of hypericin. Among the variety of potential applications hypericin can be used as photosensitizer in photodynamic therapy (PDT), where it is brought into cancer cells and produces singlet oxygen upon irradiation with a suitable light source. Therefore, the photophysical properties of hypericin are crucial for a successful application in a medical treatment. Here, we present the first single molecule optical spectroscopy study of hypericin. Its photostability is large enough to obtain single molecule fluorescence, surface enhanced Raman spectra (SERS), fluorescence lifetime, antibunching and blinking dynamics. Embedding hypericin in a PVA matrix changes the blinking dynamics, reduces the fluorescence lifetime and increases the photostability. Single molecule SERS spectra show both the neutral and deprotonated form of hypericin and exhibit sudden spectral changes, which can be associated with a reorientation of the single molecule with respect to the surface.

Finite-Temperature Supersymmetry: The Wess-Zumino Model

Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We investigate the breakdown of supersymmetry at finite temperature. While it has been proven that temperature always breaks supersymmetry, the nature of this breaking is less clear. On the one hand, a study of the Ward-Takahashi identities suggests a spontaneous breakdown of supersymmetry without the existence of a Goldstino, while on the other hand it has been shown that in any supersymmetric plasma there should exist a massless fermionic collective excitation, the phonino. Aim of this work is to unify these two approaches. For the Wess-Zumino model, it is shown that the phonino exists and contributes to the supersymmetric Ward-Takahashi identities in the right way displaying that supersymmetry is broken spontaneously with the phonino as the Goldstone fermion.

description: We have performed a systematic study of Gamma-Ray Bursts (GRBs), which have various values in the peak energy of the $νF_ν$ spectrum of the prompt emission, $E_{\rm peak}$, observed by \textsl{Swift}/BAT and \textsl{Fermi}/GBM, investigating their prompt and X-ray afterglow emissions. We cataloged the long-lasting GRBs observed by the \textsl{Swift} between 2004 December and 2014 February in 3 categories according to the classification by \citet{2008ApJ...679..570S}: X-Ray Flashes (XRFs), X-Ray Rich GRBs (XRRs), and Classical GRBs (C-GRBs). We then derived $E^{\rm obs}_{\rm peak}$, as well as $E^{\rm src}_{\rm peak}$ if viable, of the \textsl{Swift} spectra of their prompt emission. We also analyzed their X-Ray afterglows and found the trend that the GRB events with a lower $E_{\rm peak}^{\rm src}$, i.e. softer GRBs, are fainter in the 0.3--10 keV X-ray luminosity and decay more slowly than harder GRBs. The intrinsic event rates of the XRFs, XRRs, and C-GRBs were calculated, using the \textsl{Swift}/BAT trigger algorithm. That of either of the XRRs and XRFs is larger than that of the C-GRBs. If we assume that the observational diversity of $E_{\rm peak}$ is explained with the off-axis model \citep{2002ApJ...571L..31Y,2004ApJ...607L..103Y}, these results yield the jet half-opening angle of $Δθ\sim 0.3^\circ$, and the variance of the observing angles $θ_{\rm obs} \lesssim0.6^{\circ}$. This implies that the tiny variance of the observing angles of $\lesssim0.6^{\circ}$ would be responsible for the $E_{\rm peak}$ diversity observed by \textsl{Swift}/BAT, which is unrealistic. Therefore, we conclude that the $E_{\rm peak}$ diversity is not explained with the off-axis model, but is likely to originate from some intrinsic properties of the jets.

description: General-purpose crowdsourcing platforms are increasingly being harnessed for creative work. The platforms' potential for creative work is clearly identified, but the workers' perspectives on such work have not been extensively documented. In this paper, we uncover what the workers have to say about creative work on paid crowdsourcing platforms. Through a quantitative and qualitative analysis of a questionnaire launched on two different crowdsourcing platforms, our results revealed clear differences between the workers on the platforms in both preferences and prior experience with creative work. We identify common pitfalls with creative work on crowdsourcing platforms, provide recommendations for requesters of creative work, and discuss the meaning of our findings within the broader scope of creativity-oriented research. To the best of our knowledge, we contribute the first extensive worker-oriented study of creative work on paid crowdsourcing platforms.

description: Exciton-polaritons, elementary excitations arising from the strong coupling regime between photons and excitons in insulators or semiconductors, represent a promising platform for studying quantum fluids of light and realizing prospective all-optical devices. Among different materials for room temperature polaritonic devices, two-dimensional (2D) layered perovskites have recently emerged as one of the promising candidates thanks to their prominent excitonic features at room temperature. Here we report on the experimental demonstration of exciton-polaritons at room temperature in resonant metasurfaces made from a subwavelength 2D lattice of perovskite pillars. These metasurfaces are obtained via spincoating, followed by crystallization of the perovskite solution in a pre-patterned glass backbone. The strong coupling regime is revealed by both angular-resolved reflectivity and photoluminescence measurements, showing anticrossing between photonic modes and the exciton resonance with a Rabi splitting in the 200 meV range. Moreover, we show that the polaritonic dispersion can be engineered by tailoring the photonic Bloch mode to which perovskite excitons are coupled. Linear, parabolic, and multi-valley polaritonic dispersions are experimentally demonstrated. All of our results are perfectly reproduced by both numerical simulations based on a rigorous coupled wave analysis and an elementary model based on a quantum theory of radiation-matter interaction. Our results suggest a new approach to study exciton-polaritons and pave the way towards large-scale and low-cost integrated polaritonic devices operating at room temperature.

description: It is well known that conventional pairing fluctuation theory at the Hartree level leads to a normal state pseudogap in the fermionic spectrum. Our goal is to extend this Hartree approximated scheme to arrive at a generalized mean field theory of pseudogapped superconductors for all temperatures $T$. While an equivalent approach to the pseudogap has been derived elsewhere using a more formal Green's function decoupling scheme, in this paper we re-interpret this mean field theory and BCS theory as well, and demonstrate how they naturally relate to ideal Bose gas condensation. Here we recast the Hartree approximated Ginzburg-Landau self consistent equations in a T-matrix form. This recasting makes it possible to consider arbitrarily strong attractive coupling, where bosonic degrees of freedom appear at $ T^*$ considerably above $T_c$. The implications for transport both above and below $T_c$ are discussed. Below $T_c$ we find two types of contributions. Those associated with fermionic excitations have the usual BCS functional form. That they depend on the magnitude of the excitation gap, nevertheless, leads to rather atypical transport properties in the strong coupling limit, where this gap (as distinct from the order parameter) is virtually $T$-independent. In addition, there are bosonic terms arising from non-condensed pairs whose transport properties are shown here to be reasonably well described by an effective time-dependent Ginzburg-Landau theory.

description: This thesis examines narratives about the recent Puer tea fad in China, during which the production region, Yunnan, has experienced changes in both tea production and tea consumption. The thesis illustrates the unprecedented depth of the contentious fashioning and refashioning of a commodity during reform China's consumption revolution. The experience of Puer Tea demonstrates both enduring and transformed characteristics of Chinese cultural consumption. The rising commercialisation in twenty-first century China has generated multiple desires for presenting newly constructed forms of nationalism, regionalism and individualism. This is exemplified by the desire to authenticate one's unique identity via authentic Puer tea. A new discourse has emerged about Puer tea's transformative cultural value: "the longer the storage, the higher the value" (yue chen yue xiang, ????). This constructed value was, however, challenged by the flourishing market in counterfeit tea and controversy about how Puer tea itself was to be defined. This thesis links the recent history of Puer tea to the Chinese concept of jianghu, a non{u00AD}mainstream space popularly used in martial arts novels as well as in daily life, in which the actors seek to go beyond the governmental law and solve problems with self-help. This intrinsic feature of Chinese jianghu culture is crucial in understanding Puer tea's chaotic situation and the responses to this adopted by different Puer tea actors. This will explain why it has been impossible to standardise Puer tea's authenticity. Determining if tea is authentic can only be empirically, contextually and multiply self-managed via inter-personal negotiation. Drawing on previous research on the construction of meanings in relation to food, this thesis seeks to bring specific Chinese concepts into the English language literature to further highlight how a certain food's meanings can be deeply shaped by its cultural and social context. The ethnography follows Puer tea's life history from its main production areas to its sites of consumption. Film is used as an important methodology to trace the social life of Puer tea. Segments of film, to be viewed alongside the text, illustrate the social and physical landscape of tea production and visualize people's sensory experiences in tea consumption. The video seeks to go beyond textual representation and provide additional narratives about Puer tea, echoing the jianghu theme of multiple voices and alternative resolutions.

description: This thesis presents three essays on the analysis of historical meteorological data in Australia. The Australian Bureau of Meteorology has established a network of more than one thousand stations across Australia that have recordings dating from early last century, resulting in a large dataset of meteorological records. These data provide important information on the dynamics of the Australian climate system and systematic investigation using these data can help us to better understand our climate and prepare for possible changes. The purpose of this thesis is to develop models and methods to analyse such meteorological data from a statistical perspective. In Chapter 2, a spatia-temporal model is developed based on monthly average temperature data at 177 locations in south-eastern Australia over 40 years. Guided by a preliminary analysis, a model with components dealing with spatial varying mean and seasonality, short-term and long-term temporal trends is built, and the space-time interaction is modelled by the kernel-convolution method. It is shown that the temperature has become warmer in most of the south-eastern Australia during the period under investigation. In Chapter 3, a new duration-dependent Hidden Markov Model is proposed as an extension to the Hidden Markov Model (HMM) and Non-homogeneous Hidden Markov Model (NHMM) which assumes that the transition probabilities are either constant or only depend on some independent variables. The possibility of duration-dependent effects is formally considered in this chapter where the transition probabilities are allowed to be explicitly correlated to duration - how long the hidden system has been in the current state. This approach is used to model the amount of daily rainfall amount at 5 locations in Darwin, Northern Territory. For data arising from climate phenomenon, such as the temperature and rainfall data considered here, it is common for outliers to be present. The presence of outliers could unduly influence the results of any analysis that are conducted and make conclusion non-robust. But it is often difficult to detect them simultaneously because of the masking effect. Motivated by this problem, a general method is proposed in Chapter 4 for identifying multiple influential observations in regression models. The ability of this method is tested and illustrated by both a thorough simulation and several examples.
Fresh Air : Exploring Perceptions of High School Student and Teacher Participation in Daily Outdoor Walking Breaks for Health and Wellbeing
Creators: name: Robillard, Anne Elizabeth
Publisher: name: The University of British Columbia
Year: 2021

description: Introduction: The health and wellbeing of high school students in Alberta (AB) and British Columbia (BC) are at risk for concerns as their school day: 1) limits opportunities for physical activity (PA); 2) promotes sedentary behaviour with prolonged, indoor sitting; and, 3) may foster obesity, depression, and anxiety. In general, unlike elementary and junior high schools, high schools have limited opportunities for students to meet the Canadian Physical Activity Guidelines for Youth (12-17 years old) in conjunction with the Canadian Sedentary Behaviour Guidelines. Research confirms the benefits of physical activity (PA) on physical health, brain function, learning, and emotional, social, and mental wellbeing. Research also indicates that being outside in nature has positive effects on physical and mental health, social relationships, stress management, and wellbeing. The purpose of this study was to explore how participation in a daily 15-minute outdoor walking break, during subject discipline learning, shapes high school student and teacher perceptions of their health and wellbeing. Methods: A qualitative approach using Participatory Action Research (PAR) and thematic analysis were utilized. Data was collected from two teacher pre- and post-walking break online interviews, thirty-eight student post-walking break online questionnaires, and researcher field notes. Discoveries: 97% of students and 100% of teachers reported enjoying these daily outdoor walking breaks and 92% of students and 100% of teachers wanted to continue them. The overarching theme from the data was student and teacher perceptions of their health and wellbeing, discussed through the five sub-themes: outdoors, minds, bodies, relationships, and feelings. Both students and teachers testified that outdoor physical activity (OPA) had a positive impact on their mental, physical, social, and emotional health and wellbeing. Students’ top perception (51%) of their enjoyment of the daily outdoor walking breaks was related to the outdoors and specifically linked to the enjoyment of fresh air. Conclusions: Embedding a 15-minute refreshment time of daily outdoor walks within the high school curriculum should be considered by students, teachers, school administrators, and policymakers.

description: The lichens Erioderma pedicellatum (Hue) P.M. Jørg. and Erioderma mollissimum (G. Sampaio) Du Rietz are endangered species in Canada. Both species are obligate epiphytes found in forested wetlands near the Atlantic Coast. They are thought to be primarily threatened by logging and acid pollution, but the influence of these factors has not been examined at large-extents or relative to other habitat features. Critical habitat for protection has remained difficult to define beyond observed occurrences, because of the low accuracy of existing habitat models. To facilitate improved recovery planning and understanding of their ecology in the province of Nova Scotia, we created high-resolution distribution models for both species, incorporating elements of climate, forest composition, hydrology, acid pollution, and anthropogenic influence using the MaxEnt algorithm and a backwards stepwise selection process. The most important predictors were related to rainfall or an oceanic moderation of thermal optima. Depth to water table and the presence of suitable forest composition were also included, as was distance from roads for E. pedicellatum. The putative threats, acid pollution and silvicultural treatment, were not important and therefore excluded from models. Although both species have highly specific habitat requirements, E. pedicellatum appears to be more sensitive to human activities.

description: The times of temporal-network events and their correlations contain information on the function of the network and they influence dynamical processes taking place on it. To extract information out of correlated event times, techniques such as the analysis of temporal motifs have been developed. We discuss a recently-introduced, more general framework that maps temporal-network structure into static graphs while retaining information on time-respecting paths and the time differences between their consequent events. This framework builds on weighted temporal event graphs: directed, acyclic graphs (DAGs) that contain a superposition of all temporal paths. We introduce the reader to the temporal event-graph mapping and associated computational methods and illustrate its use by applying the framework to temporal-network percolation.

Classical information deficit and monotonicity on local operations

description: We investigate classical information deficit: a candidate for measure of classical correlations emerging from thermodynamical approach initiated in [Phys. Rev. Lett 89, 180402]. It is defined as a difference between amount of information that can be concentrated by use of LOCC and the information contained in subsystems. We show nonintuitive fact, that one way version of this quantity can increase under local operation, hence it does not possess property required for a good measure of classical correlations. Recently it was shown by Igor Devetak, that regularised version of this quantity is monotonic under LO. In this context, our result implies that regularization plays a role of "monotoniser".

description: New low-lying excitations are observed by inelastic light scattering at filling factors $ν=p/(ϕp \pm 1)$ of the fractional quantum Hall regime with $ϕ=4$. Coexisting with these modes throughout the range $ν\leq 1/3$ are $ϕ=2$ excitations seen at 1/3. Both $ϕ=2$ and $ϕ=4$ excitations have distinct behaviors with temperature and filling factor. The abrupt first appearance of the new modes in the low energy excitation spectrum at $ν\lesssim 1/3$ suggests a marked change in the quantum ground state on crossing the $ϕ=2 \to ϕ=4$ boundary at $ν= 1/3$.

description: In this second article of the series we study holomorphic families of generic rational matrix functions parameterized by the pole and zero loci. In particular, the isoprincipal deformations of generic rational matrix functions are proved to be isosemiresidual. The corresponding rational solutions of the Schlesinger system are constructed and the explicit expression for the related tau function is given. The main tool is the theory of joint system representations for rational matrix functions with prescribed pole and zero structures.

Data Privacy and Automated Vehicles: Navigating the Privacy Continuum
Creators: name: Brady, Mark
Publisher: name: Monash University

Subjects: subject: Law
subject: FOS: Law

description: Australia's information privacy framework fails to protect personal information contained within data generated by automated vehicles. Automated vehicles will increasingly store, share and broadcast data about the vehicle (and by implication the occupants) with rising levels of automation. Using data mining techniques, personal information contained within disparate data streams can be compiled to allow profiling of individuals to a high degree. Following the recent decision in Privacy Commissioner v Telstra Corporation Ltd ('Telstra'), Australian law does not recognise personal information unless contained within a single data stream and remains silent on how to identify personal information within data having multiple subject matters. This article argues that, post-Telstra, the privacy framework will not safeguard personal information contained within data produced by automated land vehicles.

description: This work proposes to combine neural networks with the compositional hierarchy of human bodies for efficient and complete human parsing. We formulate the approach as a neural information fusion framework. Our model assembles the information from three inference processes over the hierarchy: direct inference (directly predicting each part of a human body using image information), bottom-up inference (assembling knowledge from constituent parts), and top-down inference (leveraging context from parent nodes). The bottom-up and top-down inferences explicitly model the compositional and decompositional relations in human bodies, respectively. In addition, the fusion of multi-source information is conditioned on the inputs, i.e., by estimating and considering the confidence of the sources. The whole model is end-to-end differentiable, explicitly modeling information flows and structures. Our approach is extensively evaluated on four popular datasets, outperforming the state-of-the-arts in all cases, with a fast processing speed of 23fps. Our code and results have been released to help ease future research in this direction.
