Aboriginal use and management of fisheries in British Columbia
Creators: name: Kyle, Rosanne Marie
Publisher: name: University of British Columbia
Year: 2009

description: Both the use of and jurisdiction over fisheries resources is an important issue for many First Nations in British Columbia. Historically, fish played an important spiritual, social and economic role in numerous Aboriginal societies. These societies had various methods of managing the resource and, although they had the technological capacity to over-exploit the fisheries, they were able to maintain sustainable levels of fish. Following contact with European settlers, Aboriginal fishers were initially able to continue their traditional methods of fishing as well as expand their use of the fisheries through trade with non- Aboriginals. However, with the opening of the canneries on the coast the fisheries grew in economic importance to non-Aboriginal fishers and management of the resource was gradually but systematically taken over by the state, with various ideologies being used to justify the take-over. Aboriginal fishers lost not only their control over management of the resource, but also their ability to use it as extensively as they once had. Over the years, Aboriginal participation in both the food and commercial fisheries has declined although various government-sponsored programs have been initiated to attempt, with only partial success, to remedy this problem. In the meantime, the Department of Fisheries and Oceans has been battling other problems in the commercial fisheries, including over-capitalization of the fleet and depletion of fish stocks. Management of salmon in particular, because it is an anadromous species which travels through several different jurisdictions, has become extremely complex. It is in this context that much litigation over Aboriginal fishing has been launched. Only a few of the issues have been clarified by the judgments which have resulted and certain myths and ideologies have surfaced repeatedly in many of the decisions. It is likely that the recent decisions of the Supreme Court of Canada on Aboriginal commercial and management rights will result in increased complexity and political controversy. However, problems of fisheries management, including the accommodation of Aboriginal interests, is not unique to British Columbia or even Canada. Similar problems have been experienced elsewhere in the world and various types of co-management regimes have been established in various jurisdictions in an attempt to deal with some of these issues and to recognize a greater role for Aboriginal fishers and communities in fisheries management. It is not clear whether, and to what extent, comanagement will be adopted in British Columbia, or what the role of Aboriginal fishers might be in such a regime. Even if co-management is established, it is highly probable that the state's underlying regulatory regime will remain intact. However, co-management may result in increased Aboriginal participation in both the use and management of the resource.

description: In this work we propose a topological valley phononic crystal plate and we extensively investigate the refraction of valley modes into the surrounding homogeneous medium. This phononic crystal includes two sublattices of resonators (A and B) modeled by mass-spring systems. We show that two edge states confined at the AB/BA and BA/AB type domain walls exhibit different symmetries in physical space and energy peaks in the Fourier space. As a result, distinct refraction behaviors, especially through an armchair cut edge, are observed. On the other hand, the decay depth of these localized topological modes, which is found to be solely determined by the relative resonant strength between the scatterers, significantly affects the refraction patterns. More interestingly, the outgoing traveling wave through a zigzag interface becomes evanescent when operating at deep sub-wavelength scale. This is realized by tuning the average resonant strength. We show that the evanescent modes only exist along a particular type of outlet edge, and that they can couple with both topological interface states. We also present two designs of topological functional devices, including an elastic one-way transmission waveguide and a near-ideal monopole/dipole emitter, both based on our phononic structure.

description: Sound event detection systems are widely used in various applications such as surveillance and environmental monitoring where data is automatically collected, processed, and sent to a cloud for sound recognition. However, this process may inadvertently reveal sensitive information about users or their surroundings, hence raising privacy concerns. In this study, we propose a novel adversarial training method for learning representations of audio recordings that effectively prevents the detection of speech activity from the latent features of the recordings. The proposed method trains a model to generate invariant latent representations of speech-containing audio recordings that cannot be distinguished from non-speech recordings by a speech classifier. The novelty of our work is in the optimization algorithm, where the speech classifier's weights are regularly replaced with the weights of classifiers trained in a supervised manner. This increases the discrimination power of the speech classifier constantly during the adversarial training, motivating the model to generate latent representations in which speech is not distinguishable, even using new speech classifiers trained outside the adversarial training loop. The proposed method is evaluated against a baseline approach with no privacy measures and a prior adversarial training method, demonstrating a significant reduction in privacy violations compared to the baseline approach. Additionally, we show that the prior adversarial method is practically ineffective for this purpose.

description: We introduce an algorithm to generate multivariate series of symbols from a finite alphabet with a given hierarchical structure of similarities. The target hierarchical structure of similarities is arbitrary, for instance the one obtained by some hierarchical clustering procedure as applied to an empirical matrix of Hamming distances. The algorithm can be interpreted as the finite alphabet equivalent of the recently introduced hierarchically nested factor model (M. Tumminello et al. EPL 78 (3) 30006 (2007)). The algorithm is based on a generating mechanism that is different from the one used in the mutation rate approach. We apply the proposed methodology for investigating the relationship between the bootstrap value associated with a node of a phylogeny and the probability of finding that node in the true phylogeny.

Order-of-Magnitude SNR Improvement for High-Field EPR Spectrometers via 3D-Printed Quasioptical Sample Holders

description: In this paper, we present a rapidly-prototyped, costefficient, 3D-printed quasioptical sample holder for improving the signal-to-noise ratio (SNR) in modern, resonator-free, highfield electron paramagnetic resonance (EPR) spectrometers. Such spectrometers typically operate in induction mode: the detected EPR (cross-polar) signal is polarized orthogonal to the incident (co-polar) radiation. The sample holder improves SNR in three modes: continuous wave, pulsed, and rapid-scan. An adjustable sample positioner allows for optimizing sample position to maximize the 240 GHz magnetic field B1, and a rooftop mirror allows for small rotations of the cross-polar signal to maximize the signal and minimize the co-polar background. When optimized, the co-polar isolation (the ratio of incident to detected co-polar signal) was around 50 dB, an improvement of over 20 dB. This large isolation is especially beneficial for maximizing the SNR of rapidscan EPR, but also improves the SNR in pulsed and cwEPR experiments. Through minimal modification, the sample holder may be incorporated into a variety of homebuilt, induction-mode hfEPR spectrometers in order to significantly improve the SNR (approx. 6x), and thereby reduce the acquisition time (by more than a factor of 30).
Hierarchical orbital decompositions and extended decomposable distributions

description: Elliptically contoured distributions can be considered to be the distributions for which the contours of the density functions are proportional ellipsoids. Kamiya, Takemura and Kuriki (2006) generalized the elliptically contoured distributions to star-shaped distributions, for which the contours are allowed to be arbitrary proportional star-shaped sets. This was achieved by considering the so-called orbital decomposition of the sample space in the general framework of group invariance. In the present paper, we extend their results by conducting the orbital decompositions in steps and obtaining a further, hierarchical decomposition of the sample space. This allows us to construct probability models and distributions with further independence structures. The general results are applied to the star-shaped distributions with a certain symmetric structure, the distributions related to the two-sample Wishart problem and the distributions of preference rankings.

description: In the context of quantum field theory (QFT), we compute the amplitudes of weak interaction processes such as $ W^{+} \rightarrow e^{+} + ν_{e}$ and $ W^{+} \rightarrow e^{+} + ν_μ$ by using different representations of flavor states for mixed neutrinos. Analyzing the short time limit of the above amplitudes, we find that the neutrino states defined in QFT as eigenstates of the flavor charges lead to results consistent with lepton charge conservation. On the contrary, the Pontecorvo flavor states produce a violation of lepton charge in the vertex, which is in contrast with what expected at tree level in the Standard Model.

description: This paper calculates the amount of baryon/radiation isocurvature fluctuation produced through the decay of a curvaton field. It is shown in particular that if curvaton decay preserves baryon number and the curvaton dominates the energy density at the time of decay, the initial curvaton/radiation isocurvature mode is entirely transfered into a baryon/radiation isocurvature mode. This situation is opposite to that previously studied in three fluid models of curvaton decay; this difference is related to the conservation of the pre-existing baryon asymmetry and to the efficiency of the annihilation of all baryon/anti-baryon pairs produced in the decay. We study in detail the relevant cases in which the curvaton decay preserves or not baryon number and provide analytical and numerical calculations for each situation.

description: In this work, we study an epidemic model with vaccination coupled with opinion dynamics in a dynamic network. The network structure evolves as agents with differing opinions disconnect from one another and connect with agents that share similar opinions about vaccination. We consider a SIS-like model with an extra vaccinated state. Agents can have continuous opinions and every time an agent disconnects from a neighbor, they connect to a new neighbor. We have observed the emergence of network homophily and, in certain cases, the complete fragmentation of the network. Our Monte Carlo simulations also show first-order phase transitions with metastable states. An increase in the probability of rewiring yields a dual effect, namely: (a) in the short term, it has the potential to intensify the epidemic peak; (b) in the long term, it can diminish the rate of infection. This transient increase in the epidemic peak is attributed to the fragmentation of the network into smaller, disconnected sub-networks. Therefore, our results suggest that rewiring is optimal when it is as high as possible but before the network starts breaking apart.

description: We study the electrical and thermal transport through the SU(N) Wolff model with the use of bosonization. The Wilson ratio reaches unity as N grows to infinity. The electric conductance is dominated by the charge channel, and decreases monotonically with increasing interaction. The thermal conductivity enhances in the presence of local Hubbard U. The Wiedemann-Franz law is violated, the Lorentz number depends strongly on the interaction parameter, which can be regarded as a manifestation of spin-charge separation.

description: This paper seeks to test if the large-scale galaxy distribution can be characterized as a fractal system. Tools appropriate for describing galaxy fractal structures with a single fractal dimension $D$ in relativistic settings are developed and applied to the UltraVISTA galaxy survey. A graph of volume-limited samples corresponding to the redshift limits in each redshift bins for absolute magnitude is presented. Fractal analysis using the standard $Λ$CDM cosmological model is applied to a reduced subsample in the range $0.1\le z \le 4$, and the entire sample within $0.1\le z\le 6$. Three relativistic distances are used, the luminosity distance $d_L$, redshift distance $d_z$ and galaxy area distance $d_G$, because for data at $z\gtrsim 0.3$ relativistic effects are such that for the same $z$ these distance definitions yield different values. The results show two consecutive and distinct redshift ranges in both the reduced and complete samples where the data behave as a single fractal galaxy structure. For the reduced subsample we found that the fractal dimension is $D=\left(1.58\pm0.20\right)$ for $z<1$, and $D=\left(0.59\pm0.28\right)$ for $1\le z\le 4$. The complete sample yielded $D=\left(1.63\pm0.20\right)$ for $z<1$ and $D=\left(0.52\pm0.29\right)$ for $1\le z\le6$. These results are consistent with those found by Conde-Saavedra et al. (2015; arXiv:1409.5409v1), where a similar analysis was applied to a much more limited survey at equivalent redshift depths, and suggest that either there are yet unclear observational biases causing such decrease in the fractal dimension, or the galaxy clustering was possibly more sparse and the universe void dominated in a not too distant past.

Growth vs. integrity : environmentalism and localism in a changing community : one citizen’s participatory glimpse
Creators: name: Rudd, Jennifer Lynn
Publisher: name: University of British Columbia
Year: 2009

description: This is a case study undertaken in White Rock, a postindustrial, oceanside town of 16,000 on Canada's southwest border. The participant-observation research was undertaken between 1989 and 1993 when the author was politically active in the community. Noting a challenge to an encrusted city council from a loosely affiliated group who soon became members or supporters of the "White Rock Residents' Association", the participant intervened to explore theories about the instability of post-industria1 society and the emancipatory power of new social movements. Believing that the environmentalist social movement could attract broad public appeal and was conducive to grassroots progressive politics, the participant utilized the power of environmental ideology by publically prioritizing environmental issues while seeking a council seat as a political newcomer in a town where local elections were often uncontested. Although unsuccessful and subject to countervailing gender politics, the author placed seventh on a ballot of 11 for six council positions, outperforming several long-term and influential residents of the community. Chapter One provides a brief, overview of the research project, with further methodological discussion in Appendix A. Chapter Two gives a comparative discussion of environmentalist and localist ideologies, suggesting how they pertain to the White Rock community. Chapter Three offers a profile of the community of White Rock as it undergoes certain changes while facing environmental problems. The final chapter considers changing political and power relations between local and senior governments as they respond to environmental regional problems. During the period of intervention, new political party provincial and federal governments were elected, and in White Rock a member of the White Rock Residents' Association became the city's provincial member of the legislative assembly, while an active Reform Party member became federal member of Parliament. As well, the Boundary Board of Health won a power battle with city council to eliminate swimming at White Rock's polluted west beach, demonstrating the newly won influence of the provincial government. In exploring and comparing environmentalist and localist politics, both the research and literature review indicate that environmentalist ideology and political practice can lead to a reformation of traditional localist politics, resulting in greater influence and prestige for environmental organizations.

description: Adult stem cells are long-lived and quiescent with unique metabolic requirements. Macroautophagy/autophagy is a fundamental survival mechanism that allows cells to adapt to metabolic changes by degrading and recycling intracellular components. Here we address why autophagy depletion leads to a drastic loss of the stem cell compartment. Using inducible deletion of autophagy specifically in adult hematopoietic stem cells (HSCs) and in mice chimeric for autophagy-deficient and normal HSCs, we demonstrate that the stem cell loss is cell-intrinsic. Mechanistically, autophagy-deficient HSCs showed higher expression of several amino acid transporters (AAT) when compared to autophagy-competent cells, resulting in increased amino acid (AA) uptake. This was followed by sustained MTOR (mechanistic target of rapamycin) activation, with enlarged cell size, glucose uptake and translation, which is detrimental to the quiescent HSCs. MTOR inhibition by rapamycin treatment in vivo was able to rescue autophagy-deficient HSC loss and bone marrow failure and resulted in better reconstitution after transplantation. Our results suggest that targeting MTOR may improve aged stem cell function, promote reprogramming and stem cell transplantation.

description: Marine debris pollution is a growing problem impacting aquatic ecosystems, coastal recreation, and human society. Beaches are known to be a sink for debris, and beaching needs to be accounted for in marine debris mass balances. The process of buoyant debris beaching is not sufficiently well understood in order to include this process yet. We develop a simplified model for buoyant marine debris transport in bore-driven swash (where the water wets the beach with each incoming wave). We validate the model with laboratory experiments and use the combined results from the model and experiments to understand the parameters that are important for dictating particle beaching. The most relevant parameters are the particle inertia and the timing and velocity with which debris particles enter the swash zone.

description: Between 1959-1984, approximately 87,000 Koreans and 6,000 Japanese spouses migrated from Japan to North Korea as part of a ‘repatriation project’. This project was organised and facilitated by the Japanese and North Korean governments with the collaboration of the International Committee of the Red Cross. ‘Repatriates’ endured severe deprivation in North Korea. In the last decade, some 300 people have returned to Japan, completing a migratory loop between the Korean Peninsula and the Japanese Archipelago. These ‘Zainichi returnees’ commonly resettle in Osaka or Tokyo, areas with large ethnic Korean populations. This thesis examines the lives of Zainichi returnees, their intergenerational, transmigratory journey, and the significance of their memories of movement and resettlement in shaping a diasporic identity. I contextualise this migration within the larger social processes and historical forces that shaped the latter half of the twentieth century in Northeast Asia, and the epoch defining challenges that continue to cast a long shadow on relations between North Korea, South Korea, and Japan. I seek to address five key questions: first, how do multiple migrations affect the identity of migrants? Second, how do migrants experience and negotiate the liminality of displacement on an everyday basis? Third, what kinds of belonging emerge through the everyday lived experiences of ‘uprootedness’? Fourth, how does memory shape and inform the movement and resettlement of migrants? Fifth, what do the lives of North Koreans in exile say about the dynamics of power in contemporary Northeast Asia?

description: The hereditary spastic paraplegias (HSPs) represent a family of genetic disorders comprising at least 72 different genes with the common pathology of progressive locomotor deficits and spasticity. ATL1/SPG3A (atlastin GTPase 1) encodes an ER fusion protein that controls ER morphology, which implicates ER structure as a causal factor in HSP. Here we use Drosophila to study effects of decreased atl (atlastin) on properties of the larval body wall muscle. We found that muscle atl loss causes accumulation of aggregates containing polyubiquitin (polyUB), mostly bound to the autophagy receptor ref(2)P/SQSTM1/p62. Muscle atl loss also decreased volume and complexity of the endolysosomal network and decreased lysosome number. To determine effects of these lysosomal deficits on progression through the basal autophagy pathway, we expressed Atg8a tagged with both GFP and mCherry in a wild-type and atl mutant background. We found numerous structures containing mCherry but not GFP fluorescence in wild type, indicating that Atg8a was found mostly in mature autolysosomes. In contrast, muscles lacking atl exhibited significant amounts of GFP signal, indicating failure of autophagosome maturation with acidic lysosomes. Many of these GFP-positive puncta contained the late-endosome marker Rab7 but not Lamp1, indicating that some autophagy cargo was accumulating within amphisomes. We also found that this autophagy block was accompanied by an inability to activate the mTor kinase. Our results provide mechanistic insights into the role of atl in maintaining proper function of the autophagy pathway and suggests that certain pathologies in patients with mutations in ATL1/SPG3A might result from altered MTOR signaling. atl atlastin; ALR autophagic lysosome reformation; ER endoplasmic reticulum; GFP green fluorescent protein; HSP hereditary spastic paraplegia; Lamp1 lysosomal associated membrane protein 1 PolyUB polyubiquitin; RFP red fluorescent protein; spin spinster; mTor mechanistic Target of rapamycin; VCP valosin containing protein

description: Keyphrase extraction as a task to identify important words or phrases from a text, is a crucial process to identify main topics when analyzing texts from a social media platform. In our study, we focus on text written in Indonesia language taken from Twitter. Different from the original joint layer recurrent neural network (JRNN) with output of one sequence of keywords and using only word embedding, here we propose to modify the input layer of JRNN to extract more than one sequence of keywords by additional information of syntactical features, namely part of speech, named entity types, and dependency structures. Since JRNN in general requires a large amount of data as the training examples and creating those examples is expensive, we used a data augmentation method to increase the number of training examples. Our experiment had shown that our method outperformed the baseline methods. Our method achieved .9597 in accuracy and .7691 in F1.

The Legacy, Legality and Legitimacy of Adopting Out - Examining the legitimacy of adoption through birth mother experiences.
Creators: name: Webster, Anne Elizabeth
Publisher: name: The Australian National University
Year: 2018
Subjects: Adoption, adopting out, birth mothers, reproductive rights, vulnerability

description: This thesis investigates the disconnect between the lived experience of birth mothers who adopted out their child recently and the views of members of the public with an interest in adoption, including adoptive parents and adult adoptees. I consider the perceptions of adoption in contemporary Australia from a sociological perspective focusing on the influences and circumstances in which a birth mother might choose to adopt out her newborn. Following Misztal’s (2011a) concept of modern vulnerability, I contend that being pregnant and not wishing to parent is a micro-level experience, paralleling a societal disaster such as a tsunami or war. Either event has the potential to render individuals vulnerable as they experience something they cannot change, which has unknown repercussions, while needing to rely on others for survival. My data from focus groups and in-depth interviews with birth mothers was collected between 2012 and 2013, and illustrates the complexity of influences that impact on birth mothers and public perceptions of adoption in line with the vulnerability framework. My thesis demonstrates that while adopting out is legal in every state and territory in Australia, it has a legacy from past coercive practices that negatively influences public perception of its legitimacy today. The problematic history of adoption practice has resulted in an unsuccessful struggle to separate coercion from choice (Higgins, 2010). The predicament of a pregnant woman who does not aspire to parent is primarily a site of vulnerability in which the ability to execute choice is challenged by unpredictability, irreversibility and dependence. MIsztal’s framework provides mitigation strategies for the vulnerability experienced by a birth mother who makes the choice to adopt out, and presents a basis on which current policies could be addressed to remedy the legacy of past practices and increase interdependency, reconciliation and hope for birth mothers.

description: This thesis is a study of the behaviour of a person using the terms 'likelihood', 'certainty','confidence', etc (collectively referred to as 'likelihood judgements’), in describing event s of uncertain outcome. The study is a psychophysical one in that, given that people may be observed to make statements involving these terms, consideration is given to the way these statements are determined by characteristics of the outcome judged. In general, the question of the meaning of the terms to the subject, is avoided and no reference is made to other forms of behaviour with respect to uncertain outcomes. In the first place, the behaviour of a person judging the likelihood of an isolated outcome is discussed. Consideration is given to methods that have been employed to 'scale' the judged likelihood of an outcome. Evidence is considered that the value of an outcome on the judged likelihood scale, is positively related to its mathematical probability. Consideration is then given to the practice of describing likelihood judgements in terms of 'psychological probability'. It is suggested that this usage is based on the practice in psychophysics, of describing a stimulus dimension and its judgemental correlate, as ’objective’ and ‘subjective’ aspects of the same dimension. In this case, psychological and mathematical probabilities would be best regarded as incommensurable. Consideration is then given to the behaviour of a person when asked to judge which of two uncertain outcomes is the more likely to occur. A number of terms and concepts are introduced for the description of patterns of such judgements. Consideration is given to the consequences of the occurrence of intransitivities in relative likelihood judgements. Finally, experimental evidence is reported, consistant with the conclusion that, for at least some people, such intransitivities do occur.

description: We introduce several properties of forcing notions which imply that their lambda-support iterations are lambda-proper. Our methods and techniques refine those studied in math.LO/9906024, math.LO/0210205, math.LO/0508272 and math.LO/0605067, covering some new forcing notions (though the exact relation of the new properties to the old ones remains undecided).

description: We present results of a detailed investigation of the poorly studied X-ray pulsar XTE J1858+034 based on the data obtained with the NuSTAR observatory during the outburst of the source in 2019. The spectral analysis resulted in the discovery of a cyclotron absorption feature in the source spectrum at ~48 keV both in the pulse phase averaged and resolved spectra. Accurate X-ray localization of the source using the NuSTAR and Chandra observatories allowed us to accurately determine the position of the X-ray source and identify the optical companion of the pulsar. The analysis of the counterpart properties suggested that the system is likely a symbiotic binary hosting an X-ray pulsar and a late type companion star of K-M classes rather than Be X-ray binary as previously suggested.

Three essays on the us business cycle, expectations formation and model comparison

Publisher: name: Canberra, ACT : The Australian National University
Year: 2016

description: This thesis contributes to the vast literature on understanding the disturbances that cause recessions, testing the importance of the assumption of rational expectations in macroeconomic models, and assessing model selection criteria. The main objective is to assess structural instabilities in macroeconomic models and to develop a new econometric methodology to compare different assumptions regarding expectations formation. Chapter 2 examines the role of oil price, demand, supply and monetary policy shocks during the 2001 US slowdown and Great Recession. It replicates the structural vector autoregression (VAR) of Peersman (2005) and extends it with time-varying parameters and stochastic volatility. Significant time variation is found in some impulse responses, with evidence that the constant coefficients VAR is erroneously representing structural instabilities as shocks. All models find that a combination of shocks caused the 2001 slowdown and Great Recession, but the role of individual shocks differs across models. Chapter 3 assesses the assumption of rational expectations versus adaptive learning in a dynamic stochastic general equilibrium (DSGE) model for the US economy. Using the framework in Smets and Wouters (2007) and Slobodyan and Wouters (2012), it finds that expectations implied by the rational expectations model are comparable to the adaptive learning models for actual and survey data on consumption and inflation. This chapter also formally assesses the overall fit of the model with different assumptions regarding expectations formation using the deviance information criterion (DIC), which is not commonly used to compare DSGE models. It finds that the rational expectations model is comparable to the adaptive learning models according to this criterion. Chapter 4 proposes fast algorithms for computing the DIC based on the integrated likelihood for a variety of high-dimensional latent variable models. The DIC has been a widely used Bayesian model comparison criterion since Spiegelhalter et al. (2002) introduced the concept and Celeux et al. (2006) introduced a number of alternative definitions for latent variable models. However, recent studies have cautioned against the use of some of these variants. While the DIC computed using the integrated likelihood seems to perform well, it is rarely used in practice due to computational burden. This chapter shows that the DICs based on the integrated likelihoods have much smaller numerical standard errors compared to the other DICs.

description: Quantum computers comprise elementary logic gates that initialize, control and measure delicate quantum states. One of the most important gates is the controlled-NOT, which is widely used to prepare two-qubit entangled states. The controlled-NOT gate for single photon qubits is normally realized as a six-mode network of individual beamsplitters. This architecture however, utilizes only a small fraction of the circuit for the quantum operation with the majority of the footprint dedicated to routing waveguides. Quantum walks are an alternative photonics platform that use arrays of coupled waveguides with a continuous interaction region instead of discrete gates. While quantum walks have been successful for investigating condensed matter physics, applying the multi-mode interference for logical quantum operations is yet to be shown. Here, we experimentally demonstrate a two-qubit controlled-NOT gate in an array of lithium niobate-on-insulator waveguides. We engineer the tight-binding Hamiltonian of the six evanescently-coupled single-mode waveguides such that the multi-mode interference corresponds to the linear optical controlled-NOT unitary. We measure the two-qubit transfer matrix with $0.938\pm0.003$ fidelity, and we use the gate to generate entangled qubits with $0.945\pm0.002$ fidelity by preparing the control photon in a superposition state. Our results highlight a new application for quantum walks that use a compact multi-mode interaction region to realize large multi-component quantum circuits.

description: Thermal equilibrium properties of nanoscale systems deviate from standard macroscopic predictions due to a non-negligible coupling to the environment. For anisotropic three-dimensional materials, we derive the mean force corrections to the equilibrium state of a classical spin vector. The result is valid at arbitrary coupling strength. Specifically, we consider cubic, orthorhombic, and monoclinic symmetries, and compare their spin expectation values as a function of temperature. We underpin the correctness of the mean force state by evidencing its match with the steady state of the simulated non-Markovian spin dynamics. The results show an explicit dependence on the symmetry of the confining material. In addition, some coupling symmetries show a spin alignment transition at zero temperature. Finally, we quantify the work extraction potential of the mean force-generated inhomogeneities in the energy shells. Such inhomogeneities constitute a classical equivalent to quantum coherences.

description: Consistent SU(6) and SU(8) spin-flavor extensions of the SU(3) flavor Weinberg-Tomozawa (WT) meson-baryon chiral Lagrangian are constructed, which incorporate vector meson degrees of freedom. In the charmless sector, the on-shell approximation to the Bethe-Salpeter (BS) approach successfully reproduces previous SU(3) WT results for the lowest-lying s--wave negative parity baryon resonances. It also provides some information on the dynamics of heavier ones and of the lightest d-wave negative parity resonances, as e.g. the Lambda(1520). For charmed baryons the scheme is consistent with heavy quark symmetry, and our preliminary results in the strangeness-less charm C=+1 sector describe the main features of the three-star J^P=1/2^- Lambda_c(2595) and J^P=3/2^- Lambda_c(2625) resonances. We also find a second broad J^P=1/2^- state close to the Lambda_c(2595)
