title: Optimal and Distributed Motion Planning for Multiple Robot Systems
Creators: name: Phan Huu, Thanh
Publisher: name: UNSPECIFIED
Year: 2021

description: Within the last decades, autonomous multirobot systems have been received an increasing interest due to their enormous application potential. Motion planning algorithm is a key enabler to a greater autonomy. This thesis focuses particularly on the motion planning algorithm for the autonomous multirobot systems. The contributions of the thesis are threefold. Firstly, a novel high-order near time-optimal trajectory generation algorithm is presented for twodimensional robots. The proposed trajectory generation algorithm is numerical efficient and can be embedded for any point-to-point movement in factory and logistic automation. Moreover, the generated trajectories are not only near time-optimal but also bounded by high-order time derivatives. Time discretization effects as well as nonlinear constraints due to obstacles avoidance are incorporated into the trajectory generation algorithm. These properties of the trajectory generation algorithm are essential to high-performance industrial motion control systems. Subsequently, a novel centralized motion coordination solution is introduced, which comprises a collision avoidance algorithm and a conflict resolution algorithm. The system safety can be guaranteed by employing the collision avoidance algorithm, while deadlocks can be prevented by deploying the conflict resolution algorithm. Particularly, the theoretical safety of the collision avoidance algorithm can be proved. Moreover, the centralized coordination solution is highly modular, since it can be applied as a post process to the aforementioned trajectory generation algorithm. Consequently, all important properties such as bounded high-order derivatives or time discretization consideration can be preserved. Finally, an asynchronous distributed collision avoidance algorithm is developed for multiple passive robots translating on a grid of static rectangular intelligent agents. The distributed algorithm is deployed directly into the static intelligent agents. Furthermore, the distributed algorithm is not only able to guarantee collision-free motions but also robust with respect to stochastic arbitrarily large communication time delays. Therefore, the distributed algorithm is a key to scale existing prevalent industrial systems to another dimension.

description: Abstract: Mesothelioma is an aggressive cancer that is associated with exposure to asbestos. Although asbestos is banned in several countries, including the UK, an epidemic of mesothelioma is predicted to affect middle-income countries during this century owing to their heavy consumption of asbestos. The prognosis for patients with mesothelioma is poor, reflecting a failure of conventional chemotherapy that has ultimately resulted from an inadequate understanding of its biology. However, recent work has revolutionised the study of mesothelioma, identifying genetic and pathophysiological vulnerabilities, including the loss of tumour suppressors, epigenetic dysregulation and susceptibility to nutrient stress. We discuss how this knowledge, combined with advances in immunotherapy, is enabling the development of novel targeted therapies.

description: We discuss the three-body properties of identical bosons exhibiting large scattering length in two spatial dimensions. Within an effective field theory for resonant interactions, we calculate the leading non-universal corrections from the two-body effective range to bound-state and scattering observables. In particular, we compute the three-body binding energies, the boson-dimer scattering properties, and the three-body recombination rate for finite energies. We find significant effective range effects in the vicinity of the unitary limit. The implications of this result for future experiments are briefly discussed.

Death construal in suicide
Creators: name: Qiu, Tianyou
Publisher: name: University of British Columbia
Year: 2021

description: Suicide attempts are a leading cause of global mortality and a significant public health problem. However, most identified risk factors for suicide predict suicidal ideation, but not attempts. How suicidal individuals construe death (i.e., “death construal”) may alter the nature of suicidal ideation and reduce the barriers to making a suicide attempt. The current project was the first to examine death construal in relations to suicidal ideation and attempts. Specifically, utilizing two samples (undergraduate sample [n = 549], and community sample [n = 288]), the current research (1) investigated whether fear of death distinguishes among those with a history of suicide attempts, those with a history of suicidal ideation, and non-suicidal participants; and (2) explored whether cognitions and other emotions about death and dying distinguish among those with a history of suicidal ideation, those with a history of suicide attempts, and non-suicidal participants. Additionally, participants in the undergraduate sample were followed up over a period of 1-2 months to (3) examine temporal stability of various death construal constructs, as well as their longitudinal relationships to wish to live. Results indicated that fear of death did not meaningfully distinguish those with a history of suicide attempts from those with a history of suicidal ideation. However, several death construal variables did consistently distinguish those with a history of suicidal ideation from non-suicidal individuals across samples. Specifically, conceptualizing death as annihilation distinguished those with a history of suicidal ideation from non-suicidal individuals, and predicted future decreases in wish to live at follow-up. Moreover, a specific emotion – feeling relieved about death and dying – also distinguished those with a history of suicidal ideation from non-suicidal individuals. Most death construal variables exhibited strong stability over a 1-2 months period. These results have important implications for understanding what contributes to the development of suicidal ideation and the escalation from ideation to attempts; death construal may be more important to understanding the former rather than the later. Furthermore, the aspects of death construal that most clearly distinguish individuals with and without suicidal ideation – relief from and annihilation of pain – may represent potential treatment targets in reducing suicidal ideation.

description: We show that for any fixed accuracy and time length $T$, a {\it finite} number of $T$-time length pieces of the complete trajectories on the global attractor are capable of uniformly approximating all trajectories within the accuracy in the natural strong metric after sufficiently large time when the observed dissipative system is asymptotically compact. Moreover, we obtain the strong equicontinuity of all the complete trajectories on the global attractor. These results follow by proving the existence of a strongly compact strong trajectory attractor. The notion of a trajectory attractor was previously constructed for a family of auxiliary systems including the originally considered one without uniqueness. Recently, Cheskidov and the author developed a new framework called evolutionary system, with which a (weak) trajectory attractor can be actually defined for the original system. In this paper, the theory of trajectory attractors is further developed in the natural strong metric for our purpose. We then apply it to both the 2D and the 3D Navier-Stokes equations and a general nonautonomous reaction-diffusion system.

description: It is shown that Schwarzschild black hole and de Sitter solutions exist as exact solutions of a recently proposed relativistic covariant formulation of (power-counting) renormalizable gravity with a fluid. The formulation without a fluid is also presented here. The stability of the solutions is studied and their corresponding entropies are computed, by using the covariant Wald method. The area law is shown to hold both for the Schwarzschild and for the de Sitter solutions found, confirming that, for the $β=1$ case, one is dealing with a minimal modification of GR.

description: Given two $\left( n+1\right) \times\left( n+1\right)$-matrices $A$ and $B$ over a commutative ring, and some $k\in\left\{ 0,1,\ldots,n\right\}$, we consider the $\dbinom{n}{k}\times\dbinom{n}{k}$-matrix $W$ whose entries are $\left( k+1\right) \times\left( k+1\right)$-minors of $A$ multiplied by corresponding $\left( k+1\right) \times\left( k+1\right)$-minors of $B$. Here we require the minors to use the last row and the last column (which is why we obtain an $\dbinom{n}{k}\times\dbinom{n}{k}$-matrix, not an $\dbinom{n+1}{k+1}\times\dbinom{n+1}{k+1}$-matrix). We prove that the determinant $\det W$ is a multiple of $\det A$ if the $\left( n+1,n+1\right)$-th entry of $B$ is $0$. Furthermore, if the $\left( n+1,n+1\right)$-th entries of both $A$ and $B$ are $0$, then $\det W$ is a multiple of $\left( \det A\right) \left( \det B\right)$. This extends a previous result of Olver and the author ( arXiv:1802.02900 ).

description: Many machine learning problems can be framed in the context of estimating functions, and often these are time-dependent functions that are estimated in real-time as observations arrive. Gaussian processes (GPs) are an attractive choice for modeling real-valued nonlinear functions due to their flexibility and uncertainty quantification. However, the typical GP regression model suffers from several drawbacks: 1) Conventional GP inference scales $O(N^{3})$ with respect to the number of observations; 2) Updating a GP model sequentially is not trivial; and 3) Covariance kernels typically enforce stationarity constraints on the function, while GPs with non-stationary covariance kernels are often intractable to use in practice. To overcome these issues, we propose a sequential Monte Carlo algorithm to fit infinite mixtures of GPs that capture non-stationary behavior while allowing for online, distributed inference. Our approach empirically improves performance over state-of-the-art methods for online GP estimation in the presence of non-stationarity in time-series data. To demonstrate the utility of our proposed online Gaussian process mixture-of-experts approach in applied settings, we show that we can sucessfully implement an optimization algorithm using online Gaussian process bandits.

description: The Austroasiatic language Muak Sa-aak belongs to the Angkuic branch of thePalaungic subgroup. Speakers live primarily in eastern Shan State of Myanmar.This analysis is based on the variety of Wan Fai village. Although Burmese andChinese are influential, their primary contact language is the Tai Kadailanguage Tai Lue. Borrowing from this language is extensive, even to the extentof replacing their numerals with Tai Lue. Although Muak Sa-aak underwent theGermanic shift typical of Angkuic languages, replacing proto-voiced initialswith voiceless ones, it still retains some voiced initials. There is some evidencethat language contact may have resulted in a three-tone system, where pitchwould otherwise have been largely predictable. For the majority of rhotic-initialloan words, borrowing shows a direct correspondence of Muak Sa-aak /r/ withinitial /h/ in Tai Lue. Some evidence from Assamese Tai languages suggeststhat rather than being a replacement, this might reflect a time when Tai Luepossibly still had a rhotic.

description: Behavioral economics tells us that emotions can profoundly affect individual behavior and decision-making. Does this also apply to societies at large, i.e., can societies experience mood states that affect their collective decision making? By extension is the public mood correlated or even predictive of economic indicators? Here we investigate whether measurements of collective mood states derived from large-scale Twitter feeds are correlated to the value of the Dow Jones Industrial Average (DJIA) over time. We analyze the text content of daily Twitter feeds by two mood tracking tools, namely OpinionFinder that measures positive vs. negative mood and Google-Profile of Mood States (GPOMS) that measures mood in terms of 6 dimensions (Calm, Alert, Sure, Vital, Kind, and Happy). We cross-validate the resulting mood time series by comparing their ability to detect the public's response to the presidential election and Thanksgiving day in 2008. A Granger causality analysis and a Self-Organizing Fuzzy Neural Network are then used to investigate the hypothesis that public mood states, as measured by the OpinionFinder and GPOMS mood time series, are predictive of changes in DJIA closing values. Our results indicate that the accuracy of DJIA predictions can be significantly improved by the inclusion of specific public mood dimensions but not others. We find an accuracy of 87.6% in predicting the daily up and down changes in the closing values of the DJIA and a reduction of the Mean Average Percentage Error by more than 6%.

description: We have measured the bias voltage and field dependence of eigenmode frequencies in a magnetic tunnel junction with MgO barrier. We show that both free layer (FL) and reference layer (RL) modes are excited, and that a cross-over between these modes is observed by varying external field and bias voltage. The bias voltage dependence of the FL and RL modes are shown to be dramatically different. The bias dependence of the FL modes is linear in bias voltage, whereas that of the RL mode is strongly quadratic. Using modeling and micromagnetic simulations, we show that the linear bias dependence of FL frequencies is primarily due to a linear dependence of the perpendicular spin torque on bias voltage, whereas the quadratic dependence of the RL on bias voltage is dominated by the reduction of exchange bias due to Joule heating, and is not attributable to a quadratic dependence of the perpendicular spin torque on bias voltage.

description: This paper presents a new analytical model for calculating burst loss rate (BLR) in a slotted optical burst switched network. The analytical result leads to a framework which provides guidelines for optical burst switched networks. Wavelength converter is used for burst contention resolution. The effect of several design parameters such as burst arrival probability, wavelength conversion capability, number of slots per burst and number of wavelengths is incorporated on the above performance measure. We also extend the analytical result of BLR for different types of service classes where each service class has a reserved number of wavelengths in a network with fixed number of wavelengths. We also introduce an algorithm to calculate the resultant number of wavelength for each service classes depending on the various scenarios.

description: Abstract: Brain Health Services are a novel approach to the personalized prevention of dementia. In this paper, we consider how such services can best reflect their social, cultural, and economic context and, in doing so, deliver fair and equitable access to risk reduction. We present specific areas of challenge associated with the social context for dementia prevention. The first concentrates on how Brain Health Services engage with the “at-risk“ individual, recognizing the range of factors that shape an individual’s risk of dementia and the efficacy of risk reduction measures. The second emphasizes the social context of Brain Health Services themselves and their ability to provide equitable access to risk reduction. We then elaborate proposals for meeting or mitigating these challenges. We suggest that considering these challenges will enable Brain Health Services to address two fundamental questions: the balance between an individualized “high-risk” and population focus for public health prevention and the ability of services to meet ethical standards of justice and health equity.

description: Considerato quanto l’educazione socioemotiva sia fondamentale nell’adolescenza, è stato elaborato dal team di ricerca presieduto dai professori Antognazza e Sciaroni, in collaborazione con la University of British Columbia di Vancouver, il progetto Chiamale emozioni. A partire da questo studio, ho sviluppato il presente lavoro di diploma, attraverso il quale si è cercato di indagare quale fosse lo stato di benessere psico-fisico e le competenze socioaffettive degli studenti del primo biennio di Scuola Media. In seguito alla somministrazione di un questionario, ho raccolto dei dati che hanno mostrato come non tutti i ragazzi ai quali mi sono rivolto (quarantatré allievi della Scuola Media di Morbio Inferiore) siano in grado da un lato di valutare ed esprimere un giudizio sul proprio stato d’animo, e dall’altro come essi fatichino a vivere situazioni di rispetto e benessere all’interno di un gruppo. A seguito di ciò ho realizzato due percorsi didattici all’interno delle ore di educazione musicale, che hanno permesso agli alunni di riflettere sulle proprie emozioni grazie alla realizzazione di composizioni personali, e di collaborare tra loro attraverso attività di interpretazione musicale collettiva. In conclusione, ritengo che le sequenze siano state utili ma che, vista la complessità delle competenze socioemotive, questo tipo di intervento andrebbe ripreso nei successivi anni di scolarità, in modo che esse siano acquisite in modo consapevole da tutti gli alunni.

description: Super-resolution imaging based on single molecule localization allows accessing nanometric-scale information in biological samples with high precision. However, complete measurements including molecule orientation are still challenging. Orientation is intrinsically coupled to position in microscopy imaging, and molecular wobbling during the image integration time can bias orientation measurements. Providing 3D molecular orientation and orientational fluctuations can offer new ways to assess the degree of alignment of protein structures, which cannot be monitored by pure localization. Here we demonstrate that by adding polarization control to phase control in the Fourier plane of the imaging path, all parameters can be determined unambiguously from single molecules: 3D spatial position, 3D orientation and wobbling or dithering angle. The method, applied to fluorescent labels attached to single actin filaments, provides precisions within tens of nanometers in position and few degrees in direction.

description: The rapid development of telecommunication networks is driven by user demands for new applications and advances in technologies. The explosive growth of the internet traffic is due to its use for collecting the information, communication, multimedia application, entertainment, etc. These applications are imposing a tremendous demand for bandwidth capacity on telecommunication network. The introduction of fiber optics had proved to meet the huge demand of bandwidth. These requirement can be meet by all optical network which is capable of transmitting enormous data at very high speed, around 50 Tera bits per seconds (Tbps) A wavelength conversion technique is addressed in this paper to reduced the blocking probability in wavelength routed networks. It is seen that the blocking probability of traffic requests decreases as the wavelength conversion factor increases. We explode the possibility for network with different size with variation in wavelength per link. In this work the evaluation of wavelength routed optical network with varying number of wavelength converters, different traffic types are carried out and results are shown that the blocking probability is minimum with 50% to 60% wavelength convertible nodes. Wavelength convertible nodes more than 60% are not showing much effect on reduction in blocking probability rather it results in increase in overall cost of network.

Here we show that WDM halos do not have cores that are large fractions of the halo size: typically, r_core/r_200 < 0.001. This suggests an astrophysical origin for the large cores observed in these galaxies, as has been argued by other authors.

description: Il lavoro di Tesi è stato svolto in una Scuola dell’Infanzia del Canton Ticino nella quale si è svolto un percorso di Mindfulness. La Mindfulness è uno stato di piena consapevolezza che permette di stare nel momento presente; raggiungendo questo stato si ottengono notevoli benefici sul benessere psico-fisico. Si è portata questa pratica nella scuola proponendo ai bambini sei incontri nei quali si è svolto un riscaldamento del corpo, degli esercizi di respirazione e di posture (accompagnati dalla lettura di una storia e le relative immagini) seguiti infine da un rilassamento. Lo scopo generale di questo percorso era di proporre ai bambini una modalità per imparare a stare nel presente e a conoscersi meglio. Il fine più specifico è stato invece quello di sondare se il percorso di Mindfulness avesse un’influenza positiva sulla capacità di attenzione e nella percezione dello schema corporeo. Dall’analisi dei dati, raccolti tramite delle schede logico-matematiche per l’attenzione e dei disegni per lo schema corporeo (entrambi proposti in modalità pre e post), si sono osservati dei miglioramenti nelle capacità attentive degli allievi, come il tempo di esecuzione, la correttezza, il focus del bambino durante il compito (sguardo, postura, parlare). La percezione dello schema corporeo invece non ha subito particolari evoluzioni. Al di là dei risultati puntuali emersi il percorso ha rivelato benefici per tutti gli attori che vi hanno partecipato: è stato molto interessante dalla prospettiva di docente e molto coinvolgente per i bambini interessati.

description: Contextuality is a key feature of quantum mechanics, as was first brought to light by Bohr and later realised more technically by Kochen and Specker. Isham and Butterfield put contextuality at the heart of their topos-based formalism and gave a reformulation of the Kochen-Specker theorem in the language of presheaves. Here, we broaden this perspective considerably (partly drawing on existing, but scattered results) and show that apart from the Kochen-Specker theorem, also Wigner's theorem, Gleason's theorem, and Bell's theorem relate fundamentally to contextuality. We provide reformulations of the theorems using the language of presheaves over contexts and give general versions valid for von Neumann algebras. This shows that a very substantial part of the structure of quantum theory is encoded by contextuality.

description: We investigate the emission properties that a large-scale helical magnetic field imprints on AGN jet synchrotron radiation. A cylindrically symmetric relativistic jet and large-scale helical magnetic field produce significant asymmetrical features in transverse profiles of fractional linear polarization, intensity, Faraday rotation, and spectral index. The asymmetrical features of these transverse profiles correlate with one another in ways specified by the handedness of the helical field, the jet viewing angle (theta_ob), and the bulk Lorentz factor of the flow (Gamma). Thus, these correlations may be used to determine the structure of the magnetic field in the jet. In the case of radio galaxies (theta_ob~1 radian) and a subclass of blazars with particularly small viewing angles (theta_ob << 1/Gamma), we find an edge-brightened intensity profile that is similar to that observed in the radio galaxy M87. We present observations of the AGNs 3C 78 and NRAO 140 that display the type of transverse asymmetries that may be produced by large-scale helical magnetic fields.

description: Graph sparsification underlies a large number of algorithms, ranging from approximation algorithms for cut problems to solvers for linear systems in the graph Laplacian. In its strongest form, "spectral sparsification" reduces the number of edges to near-linear in the number of nodes, while approximately preserving the cut and spectral structure of the graph. In this work we demonstrate a polynomial quantum speedup for spectral sparsification and many of its applications. In particular, we give a quantum algorithm that, given a weighted graph with $n$ nodes and $m$ edges, outputs a classical description of an $ε$-spectral sparsifier in sublinear time $\tilde{O}(\sqrt{mn}/ε)$. This contrasts with the optimal classical complexity $\tilde{O}(m)$. We also prove that our quantum algorithm is optimal up to polylog-factors. The algorithm builds on a string of existing results on sparsification, graph spanners, quantum algorithms for shortest paths, and efficient constructions for $k$-wise independent random strings. Our algorithm implies a quantum speedup for solving Laplacian systems and for approximating a range of cut problems such as min cut and sparsest cut.

Nominalization in Pnar
Creators: name: Ring, Hiram
Publisher: name: Mon-Khmer Studies Journal
Year: 2014
Subjects: subject: pbv
subject: nominalization, grammatical gender, derivation, relativisation

description: Pnar, an Austroasiatic (AA) language located in the state of Meghalaya innortheast India, is typologically interesting because of its range ofnominalization strategies. These include derivational verbal morphology,pronominal gendered noun-class clitics that derive nouns when they attach toverbs, and a relativizer. The relativizer /wa/ has intriguing similarities to thefunction of some nominalizers in nearby Tibeto-Burman languages (asidentified by Matisoff (1972) for Lahu, and for other languages in the area byNoonan (1997); Bickel (1999); Watters (2008) among others). Unlike most TBlanguages, however, this relativizer is pre-verbal, more similar to constructionsin other AA languages. Similar in form is the /wa/ ‘with/and’ comitativecoordinator that also occurs in Pnar. In this paper I review the morphemes, theirsyntax and interaction.
Use of peptide-MHC II-specific-chimeric antigen receptor Tregs to regulate autoimmunity in type 1 diabetes
Creators: name: Fung, Vivian
Publisher: name: University of British Columbia
Year: 2023

description: In type 1 diabetes (T1D), autoreactive T cells mediate the destruction of insulin-producing islet beta cells, leading to an inability to regulate blood glucose. If the patient cannot control their disease, the prolonged insulin deficiency will cause chronic hyperglycaemia, which may result in blindness and organ failure. Autoreactive T cells initiate pathogenesis upon recognition of islet-derived peptides presented by major histocompatibility complexes (MHC). In healthy individuals, these autoimmune reactions are normally suppressed by regulatory T cells (Tregs), but people with T1D are thought to have dysfunctional Tregs. Potential therapeutic strategies for T1D designed to minimize autoimmunity include pharmacological T cell inhibition and/or infusion of polyclonal Tregs. However, these strategies are non-specific and may have limited effects on beta-cell-directed autoimmunity. Research using the non-obese diabetic (NOD) mouse model has shown cell therapy with Tregs bearing a transgenic T cell receptor (TCR) specific towards an islet-derived antigen could be superior to prevent and/or reverse T1D. However, limitations of TCR-engineered Tregs include mispairing with the chains of the endogenous TCR and potential cross-reactivity with other peptides. I sought to overcome these limitations by engineering Tregs utilizing chimeric antigen receptor (CAR) technology. Advantages of CARs include high-affinity antibody-based interactions and self-contained co-stimulation. I studied two CARs in the NOD mouse model: the 1B2 CAR (specific towards insulin B₁₀-₂₃ complexed to MHC Class II I-Ag⁷) and the FS1 CAR (specific towards p63:I-Ag⁷). I validated CAR specificity by testing their binding capacity to peptide:I-Ag⁷ tetramers. Proliferation and suppression assays were conducted to compare the function of CAR Tregs versus polyclonal Tregs. I found when IB2 or FS1 CAR Tregs were cultured with splenocytes pulsed with relevant peptide, they proliferated and upregulated activation markers. FS1 CAR Tregs mediated enhanced suppression of T cell proliferation, and both 1B2 and FS1 CAR Tregs suppressed cytokine production more efficiently than polyclonal Tregs. Together, these proof-of-concept data show that T1D-peptide-MHC II-specific CARs can be used to re-direct the specificity of Tregs. These data set the stage for future testing in in vivo models of T1D and the development of similar therapeutic strategies for use in people with T1D.

description: Low temperature magnetic and structural behavior of the extended Kagome system YBaCo4O7 has been studied by single crystal neutron diffraction and high-resolution powder X-ray diffraction. Long-range magnetic ordering associated with a structural transition from orthorhombic Pbn2_1 to monoclinic P2_1 symmetry has been found at T_1 ~ 100 K. The interplay between the structural and magnetic degrees of freedom testifies that the degeneracy of the magnetic ground state, present in the orthorhombic phase, is lifted through a strong magnetoelastic coupling, as observed in other frustrated systems. At T_2 ~ 60 K, an additional magnetic transition is observed, though iso-symmetric. Models for the magnetic structures below T_1 and T_2 are presented, based on refinements using a large number of independent reflections. The results obtained are compared with previous single crystal and powder diffraction studies on this and related compositions.
