description: Self-driving cars and autonomous vehicles are revolutionizing the automotive sector, shaping the future of mobility altogether. Although the integration of novel technologies such as Artificial Intelligence (AI) and Cloud/Edge computing provides golden opportunities to improve autonomous driving applications, there is the need to modernize accordingly the whole prototyping and deployment cycle of AI components. This paper proposes a novel framework for developing so-called AI Inference Engines for autonomous driving applications based on deep learning modules, where training tasks are deployed elastically over both Cloud and Edge resources, with the purpose of reducing the required network bandwidth, as well as mitigating privacy issues. Based on our proposed data driven V-Model, we introduce a simple yet elegant solution for the AI components development cycle, where prototyping takes place in the cloud according to the Software-in-the-Loop (SiL) paradigm, while deployment and evaluation on the target ECUs (Electronic Control Units) is performed as Hardware-in-the-Loop (HiL) testing. The effectiveness of the proposed framework is demonstrated using two real-world use-cases of AI inference engines for autonomous vehicles, that is environment perception and most probable path prediction.

description: The motivations for simulating QCD thermodynamics with Wilson fermions and a twisted mass term are introduced. The twisted mass approach provides a natural infrared cutoff and O(a) improvement at maximal twist, and can be extended to finite temperature. Our strategy for exploring the QCD phase diagram at finite temperature in this setup, while taking advantage of the results at T=0, is explained. The first results for the order parameters and susceptibilities on a 16^3 x 8 lattice are presented. All dynamical simulations are carried out on the apeNEXT facility in Rome.

State, society and Buddhism in Myanmar in the 1990s : a case study of Thamanya

subject: Buddhism and state HistoryBurma

description: This study argues that popular Burmese Buddhist resurgence in the early 1990s symbolized unprecedented insecurity and disorientation that were associated with the political transition in Burma during those years. The charismatic Thamanya Sayadaw who is the subject of this thesis was an influential Buddhist monk. He and his monastery became famous all over Burma as a centre of pilgrimage and came to bear tremendous influence in Burmese society because the moral teachings and ethical behaviour instituted there provided an answer to the insecurity and oppression outside. However the Burmese resurgence represented by Thamanya, unlike other Burmese Buddhist movements, neither resisted nor supported the authoritarianism of the Burmese state. Thamanya was essentially a non-political Buddhist movement that focused on ordinary affairs. As a result, the popular Thamanya Sayadaw and his Thamanya pilgrim centre succeeded in accommodating diverse social needs and backgrounds. Nevertheless, due to their mass followers and potential political force, popular Buddhism at Thamanya was monitored closely by the state. One remarkable characteristic of popular Buddhism was the leading role of Buddhist laities who came from civil backgrounds such as refugee and city visitors. They took leading role in legitimating Thamanya Sayadaw as an extraordinary monk and at the same time they also worked to advocate their own social and economic development. This lay leadership of popular Buddhism constitutes perhaps one of its most significant influences on the state.
The Validity Of The Agreement On The Property Regime of Spouses Under The Vietnamese Marriage And Family Law - Some Inadequacies And Recommendations For Improvement

description: Abstract

The right of spouses to agree on the property regime in marriage is a newly recognized issue in the Vietnamese marriage and family law. The recognition of the right of spouses to agree on the property regime in marriage is consistent with the reality of life and in harmony with the laws of other countries. However, due to its recent recognition, the provisions on the agreement on the property regime of spouses in Vietnamese law still have some limitations and shortcomings that need to be further studied for improvement. This article studies the issue of the validity of the agreement on the property regime of spouses in the Vietnamese marriage and family law. On that basis, the article points out the limitations and shortcomings and makes recommendations to improve the provisions of the marriage and family law related to the validity of the agreement on the property regime of spouses.

description: Physical processes such as re-ignition, enhancement, and fading of active galactic nuclei (AGN) are not entirely understood because the timeline of these events is expected to last many years. However, it is well known that the differences in the energy budget between AGN components, like the optical ionizing region and the mid-infrared (MIR) dust echoes, can be interpreted as a hint on AGN evolution. Here we present a catalog of 88 AGN candidates showing hints on the fading and rising of their activity in the nearby Universe. We use AGN scaling relations to select them from an initial sample of 877 candidates using publicly available optical, X-ray, and MIR luminosities. We then use the multi-wavelength information to discard sources contaminated with extranuclear emission and those with an X-ray luminosity not well corrected for absorption. We find that 96% of our candidates are fading sources. This result suggests a scenario where the Universe had its peak of AGN activity somewhere in the past and is dominated by a fading phase at the present time. Alternatively, the fading phase is longer than the rising phase, which is consistent with galaxy merger simulations. Around 50% of these fading candidates are associated with merging or interacting systems. Finally, we also find the existence of jets in ~30% of these candidates and that the preferred AGN dust geometry is torus-like, instead of wind-like. Our results are compatible with the fading of nuclear activity, expected if they are in an inefficient state.

On a problem of Molluzzo concerning Steinhaus triangles in finite cyclic groups

description: Let $X$ be a finite sequence of length $m\geq 1$ in $\mathbb{Z}/n\mathbb{Z}$. The \textit{derived sequence} $\partial X$ of $X$ is the sequence of length $m-1$ obtained by pairwise adding consecutive terms of $X$. The collection of iterated derived sequences of $X$, until length 1 is reached, determines a triangle, the \textit{Steinhaus triangle $ΔX$ generated by the sequence $X$}. We say that $X$ is \textit{balanced} if its Steinhaus triangle $ΔX$ contains each element of $\mathbb{Z}/n\mathbb{Z}$ with the same multiplicity. An obvious necessary condition for $m$ to be the length of a balanced sequence in $\mathbb{Z}/n\mathbb{Z}$ is that $n$ divides the binomial coefficient $\binom{m+1}{2}$. It is an open problem to determine whether this condition on $m$ is also sufficient. This problem was posed by Hugo Steinhaus in 1963 for $n=2$ and generalized by John C. Molluzzo in 1976 for $n\geq3$. So far, only the case $n=2$ has been solved, by Heiko Harborth in 1972. In this paper, we answer positively Molluzzo's problem in the case $n=3^k$ for all $k\geq1$. Moreover, for every odd integer $n\geq3$, we construct infinitely many balanced sequences in $\mathbb{Z}/n\mathbb{Z}$. This is achieved by analysing the Steinhaus triangles generated by arithmetic progressions. In contrast, for any $n$ even with $n\geq4$, it is not known whether there exist infinitely many balanced sequences in $\mathbb{Z}/n\mathbb{Z}$. As for arithmetic progressions, still for $n$ even, we show that they are never balanced, except for exactly 8 cases occurring at $n=2$ and $n=6$.

description: The growth of single wall carbon nanotubes (SWCNT) inside host SWCNTs remains a compelling alternative to the conventional catalyst induced growth processes. It not only provides a catalyst free process but the ability to control the constituents of the inner tube if appropriate starting molecules are used. We report herein the growth of inner SWCNTs from $^{13}$C labeled toluene and natural carbon C$_{60}$. The latter molecule is essentially a stopper which acts to retain the smaller toluene. The Raman spectrum of the inner nanotubes is anomalous as it contains a highly isotope shifted "tail", which cannot be explained by assuming a homogeneous distribution of the isotopes. {\color{black}Semi-empirical} calculations of the Raman modes indicate that this unsual effect is explicable if small clusters of $^{13}$C are assumed. This indicates the absence of carbon diffusion during the inner tube growth. When combined with appropriate molecular recognition, this may enable a molecular engineering of the atomic and isotope composition of the inner tubes.
Development, dialectic and dominion : NGO development approaches and the semi-Asiatic mode of production in Isaan and Bangkok

Subjects: subject: HB241.H38 2011
subject: Production (Economic theory)

subject: Dialectical materialism
subject: Economic development

description: This thesis is in three parts. The first part draws upon the work of Sraffa (1960) and Gregory (1982) from the neo-Ricardian economic tradition, and Keen (l993a; 1993b) who uncovers a dialectical theory of value in Marx consistent with Sraffa's thought. This dialectical theory of value is used to reformulate the concept of modes of production within neo-Ricardian framework. In the second part, it is argued that the version of an Asiatic mode of production which many Thai scholars have argued characterised Thailand's history (Chatthip Nartsupha and Suthy Prasartset 1981;Chatthip Nartsupha 1999), is internally inconsistent. Instead, a "semi-Asiatic" or labour-short mode characterised both state and village in pre-modern central Thailand (Siam) and still provides ideological legitimacy to the Thai ruling class. As an ideology of governance, it acts to limit the discourse of development by restricting the political power and geographic and economic mobility of Thailand's lower classes. This semi-Asiatic mode explains many historical features of rural communities valorised by a significant section of Thailand's NGOand civil society movement. This part takes a multidisciplinary approach, drawing upon anthropology, archaeology, Marxist and post-Marxist economics, history and political theory to analyse the articulated, core/periphery political economy of Bangkok and North-East Thailand (Isaan). In the third part, based upon fieldwork conducted in 2002-3, case studies of three rural economic development projects supported by Thai NGOs are presented, with a focus upon their attitude towards migration and whether they meet the aspirations of their target groups and participants. It is argued that the class attitudes of the semi-Asiatic mode have remained as an elite ideology which shapes the perspective NGO projects adopt towards the residents of Isaan, particularly on the issue of migration. In resistance to this ideology, it is suggested that Thai villagers are embracing capitalist development to a much greater extent than their NGO patrons through the act of labour migration. The thesis concludes that migration between centre and periphery is a key area of class contestation in Thailand, and examines the political economy of internal migration. A postscript applies this analysis to the recent red shirt/yellow shirt clashes.

description: Space-grade Si and GaAs solar cells were irradiated with 15 & 40 MeV Li ions. Illuminated (AM0 condition) and unilluminated I-V curves reveal that the effect of high-energy Li ion irradiation has produced similar effects to that of proton irradiation. However, an additional, and different, defect mechanism is suggested to dominate in the heavier-ion results. Comparison is made with proton-irradiated solar-cell work and with non-ionizing energy-loss (NIEL) radiation-damage models.

description: Radio over Fiber networks seem to be a good answer to the two fundamental needs that the modern networks research raises. The first issue is the high bandwidth (use of fiber) and the second is high user mobility (wireless communication). RoF networks peculiarites overocme the classical cellular networks schemes and lead us to the use of modern user-oriented approaches as MEC. In this thesis we initially do a theoretical overview of the issues that RoF networks raise. We also suggest a control scheme for this kind of networks which uses multi agent softare in order to integrate the capability of using modern Artificial Intelligence technics. Finally, we demonstrate the simulation results that came up by using such a software scheme and MEC related to specific user mobility patterns.

description: Although indoor localization has been a wide researched topic, obtained results may not fit the requirements that some domains need. Most approaches are not able to precisely localize a fast moving object even with a complex installation, which makes their implementation in the automated driving domain complicated. In this publication, common technologies were analyzed and a commercial product, called Marvelmind Indoor GPS, was chosen for our use case in which both ultrasound and radio frequency communications are used. The evaluation is given in a first moment on small indoor scenarios with static and moving objects. Further tests were done on wider areas, where the system is integrated within our Robotics Operating System (ROS)-based self-developed 'Smart PhysIcal Demonstration and evaluation Robot (SPIDER)' and the results of these outdoor tests are compared with the obtained localization by the installed GPS on the robot. Finally, the next steps to improve the results in further developments are discussed.

description: We calculate one-loop corrections to the decays of the next-to-lightest neutralino $\tildeχ_2^0$ into the lightest neutralino $\tildeχ_1^0$ and two leptons; this includes diagrams where a real photon is emitted. In cases where two-body decays $\tildeχ_2^0 \to \tilde{l}^\pm_1 l^\mp \to \tildeχ_1^0 l^- l^+$ are kinematically allowed, we calculate these decays both with and without the single-pole approximation, and find consistent results. For example, for the minimal supergravity parameter set SPS1a, the integrated partial widths (the branching ratios) for $\tildeχ_2^0\to \tildeχ_1^0 l^- l^+ (l = e, μ)$ are enhanced by about 15.5 (13.6) percent by the one-loop corrections. We also study a scenario where $\tilde χ_2^0$ cannot undergo two-body decays, and find corrections to these branching ratios of about 13.6 percent. Moreover, we study the dilepton invariant mass ($M_{l^+ l^-}$) distribution, whose endpoint is often used in analyses that aim to reconstruct (differences of) supersymmetric particle masses at the LHC. The shape of this distribution is altered significantly by the emission of hard photons. For example, for the SPS1a parameter set the peak of the $M_{l^+ l^-}$ distribution is shifted by several GeV when these contributions are included.

description: The complex interplay of magnetohydrodynamics, gravity, and supersonic turbulence in the interstellar medium (ISM) introduces non-Gaussian structure that can complicate comparison between theory and observation. We show that the Wavelet Scattering Transform (WST), in combination with linear discriminant analysis (LDA), is sensitive to non-Gaussian structure in 2D ISM dust maps. WST-LDA classifies magnetohydrodynamic (MHD) turbulence simulations with up to a 97\% true positive rate in our testbed of 8 simulations with varying sonic and Alfvénic Mach numbers. We present a side-by-side comparison with two other methods for non-Gaussian characterization, the Reduced Wavelet Scattering Transform (RWST) and the 3-Point Correlation Function (3PCF). We also demonstrate the 3D-WST-LDA and apply it to classification of density fields in position-position-velocity (PPV) space, where density correlations can be studied using velocity coherence as a proxy. WST-LDA is robust to common observational artifacts, such as striping and missing data, while also sensitive enough to extract the net magnetic field direction for sub-Alfvénic turbulent density fields. We include a brief analysis of the effect of point spread functions and image pixelization on 2D-WST-LDA applied to density fields, which informs the future goal of applying WST-LDA to 2D or 3D all-sky dust maps to extract hydrodynamic parameters of interest.

A narrative study of the experiences of immigrant parents in caring for their child with autism
Creators: name: Wallace, Glenda
Publisher: name: University of British Columbia
Year: 2009

description: This study explored the experiences of immigrant parents caring for their child with autism. It has been suggested that families living with a child with autism are more likely to experience higher levels of stress compared to families who have typical children. Increased stress is also evident in immigrant families as they are exposed to new beliefs, values, and world views. Literature suggests that the experience of immigrant families and autism has not been explored. Hence, an exploratory investigation was conducted to investigate questions pertaining to these parents' experiences, and to generate questions for further research. A narrative paradigm was employed and focused on the experiences of three pairs of immigrant parents caring for a child with autism. The participants interviewed shared their experiences from their countries of origin; their current situations in Vancouver, B.C.; and their speculations and insights about the future. The narrative interviews were audio-taped, transcribed, and analyzed to develop a rich description of the participants' experiences. A systems - ecological approach was used to examine the topics in terms of relationships and subsequently applied to Christa Hoffman-Riem's conceptualization of "emotional normalization" (Hoffman-Riem, 1980). Each of the experiences described in this study was unique and reflected the experiences of the primary participants from their own perspectives. Parents were primarily concerned about their child with autism as compared to the stresses related to immigration. From these experiences, common issues emerged in areas such as behaviour; social support; communication; family functioning styles and family related concerns; general stress; self-care; religion and spirituality; integration; finances; child care; formal and informal support systems; parent advocacy; education and related services; independence and future concerns.

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: The highlights of studies of mixing among scalar mesons below and above 1 GeV within a nonlinear chiral Lagrangian framework is briefly presented. Two scalar meson nonets are introduced to explore the mass spectrum and decay properties of the $I$=1/2 and $I$=1 scalar states. For the $I$=0 states, in addition to these two nonets a scalar glueball component is also taken into account, and together with the constraints from the $I$=1/2 and $I$=1 sectors, their mass spectrum is studied. The fact that an ideally mixed $q {\bar q}$ scalar nonet has a mass ordering which is opposite to that of an ideally mixed four-quark scalar nonet is exploited to gain some insight into the quark substructure of the $I$=1/2, $I$=1 and $I$=0 states below and above 1 GeV. Consequently, numerical estimates of various components of these states (two quark and four quark components of $I$=1/2 and $I$=1 states, and two quark, four quark and glue component of $I$=0 states) are determined.

description: By a fortunate coincidence the writer discovered Morfi's History of Texas in the National Library of Mexico. For a long time this work was known only by name and its existence had come to be doubted. It is, however, the most complete and detailed account known to the present for the entire period from 1673 to 1779. Convinced of its importance for the study of the history of Spanish Texas, the writer here presents for the first time a critical edition of this work with such information on the life of the author as he has been able to find

description: We investigate the roles of non-Hermitian topology in spectral properties and entanglement structures of open systems. In terms of spectral theory, we give a unified understanding of two interpretations of non-Hermitian topology: quantum anomaly and non-Hermitian skin effects, in which the bulk spectra extremely depend on the boundary conditions. In this context, the fact that the intrinsic higher-dimensional skin effects under the full open boundary condition need the presence of the topological defects is understood in terms of the anomalous fermion production such as the Rubakov-Callan effect in the presence of the magnetic monopole. In terms of the entanglement structure, we investigate steady states of fermionic open systems whose Liouvillian (rapidity) spectra host non-Hermitian topology. We analyze dissipation-driven Majorana steady states in zero-dimensional open systems and relate them to the Majorana edge modes of topological superconductors by using the entanglement entropy. We also analyze a steady state of a one-dimensional open Fermi system with a non-Hermitian topological spectrum and relate it to the chiral edge states of the Chern insulator on the basis of the trace index defined from the entanglement spectrum. These correspondences indicate that the entanglement generates circular nonreciprocal currents under the periodic boundary condition and the skin-effect voltage with fermion accumulation under the open boundary condition. Finally, we discuss several related topics such as pseudospectral behaviors of Liouvillian dynamics and skin effects in interacting systems.

description: We introduce a protocol to transfer excitations between two noninteracting qubits via purely dissipative processes (i.e., in the Lindblad master equation there is no coherent interaction between the qubits). The fundamental ingredients are the presence of collective (i.e. nonlocal) dissipation and unbalanced local dissipation rates (the qubits dissipate at different rates). The resulting quantum trajectories show that the measurement backaction changes the system wave function and induces a passage of the excitation from one qubit to the other. While similar phenomena have been witnessed for a non-Markovian environment, here the dissipative quantum state transfer is induced by an update of the observer knowledge of the wave function in the presence of a Markovian (memoryless) environment -- this is a single quantum trajectory effect. Beyond single quantum trajectories and postselection, such an effect can be observed by histogramming the quantum jumps along several realizations at different times. By investigating the effect of the temperature in the presence of unbalanced local dissipation, we demonstrate that, if appropriately switched on and off, the collective dissipator can act as a Maxwell's demon. These effects are a generalized measure equivalent to the standard projective measure description of quantum teleportation and Maxwell's demon. They can be witnessed in state-of-the-art setups given the extreme experimental control in, e.g., superconducting qubits or Rydberg atoms.

description: Nonlinear optics is an increasingly important field for scientific and technological applications, owing to its relevance and potential for optical and optoelectronic technologies. Currently, there is an active search for suitable nonlinear material systems with efficient conversion and small material footprint. Ideally, the material system should allow for chip-integration and room-temperature operation. Two-dimensional materials are highly interesting in this regard. Particularly promising is graphene, which has demonstrated an exceptionally large nonlinearity in the terahertz regime. Yet, the light-matter interaction length in two-dimensional materials is inherently minimal, thus limiting the overall nonlinear-optical conversion efficiency. Here we overcome this challenge using a metamaterial platform that combines graphene with a photonic grating structure providing field enhancement. We measure terahertz third-harmonic generation in this metamaterial and obtain an effective third-order nonlinear susceptibility with a magnitude as large as 3$\cdot$10$^{-8}$m$^2$/V$^2$, or 21 esu, for a fundamental frequency of 0.7 THz. This nonlinearity is 50 times larger than what we obtain for graphene without grating. Such an enhancement corresponds to third-harmonic signal with an intensity that is three orders of magnitude larger due to the grating. Moreover, we demonstrate a field conversion efficiency for the third harmonic of up to $\sim$1% using a moderate field strength of $\sim$30 kV/cm. Finally we show that harmonics beyond the third are enhanced even more strongly, allowing us to observe signatures of up to the 9$^{\rm th}$ harmonic. Grating-graphene metamaterials thus constitute an outstanding platform for commercially viable, CMOS compatible, room temperature, chip-integrated, THz nonlinear conversion applications.
Consecutive gold[I]-catalysed cyclisation reactions leading to polyfused heterocycles of agrochemical relevance

description: Variolin B, a marine natural product isolated from the Antarctic sponge Kirkpatrickia variolosa, possesses a rare heterocyclic framework and is a potent CDK inhibitor. Such properties have prompted the industry partner associated with this project, namely the German chemical commodities company BASF, to select this compound as a lead for the development of new agrochemicals. This thesis details the development of new synthetic methods specifically designed to produce complex heterocyclic frameworks related to variolin B. The synthetic plan, which involved consecutive electrophile-promoted nucleophilic ring-closure reactions of 1-[2-(buta-1,3-diynyl)pyridyl]ureas potentially leading to pyrido[3',2':4,5]pyrrolo[1,2-c]pyrimidin-9(8H)-ones, is outlined in Chapter One. The first part of Chapter Two describes the synthesis of alkynylphenylureas as model cascade cyclisation precursors and the second part details the outcomes of reactions of these model compounds with various sources of iodine. The reactions delivered mono-cyclised compounds in some cases although intermolecular side-reactions prevented cascading cyclisation reactions from occurring. Details of the successful development of consecutive gold-catalysed nucleophilic ring-closure reaction of 2-(buta-1,3-diynyl)phenylureas that deliver pyrimido[1,6-a]indol-1(2H)-ones are provided in Chapter Three. The effect that substituents have on the outcome of these gold-promoted reactions were also assessed and it was found that N,N'-disubstituted cyclisation precursors give 1-methylene-1H-imidazo[1,5-a]indol-3(2H)-ones as the major products. Chapter Four outlines the preparation of pyridine-based cyclisation precursors and attempts to synthesise variolin B by applying the gold-catalysed cyclisation methodology to them. These reactions led to mono-cyclised products in some cases but side reactions were also observed. Many of the heterocycles produced during the course of this work are unprecedented and, accordingly, they are being tested for their agrochemical properties by BASF Crop-Protection Division. This aspect of the work is discussed in Appendix 1.
Toward a communication framework of relational stigma management in nontraditional relationships

description: Individuals in nontraditional relationships can experience stigma, prejudice, and discrimination from the social devaluation of their union. Research has demonstrated that stigma generally has adverse consequences of physical and mental health outcomes and relational functioning (e.g., Doyle & Molix, 2015; Frost, 2013; Lehmiller & Agnew, 2006, 2007; Pascoe & Smart Richman, 2009). The ways individuals choose to manage stigma is related to distinct outcomes (Meisenbach, 2010; Thompson & Seibold, 1978). During stressful moments, positive relational maintenance efforts are critical to guard against psychological distress as well as preserve and strengthen the relationship (Afifi et al., 2016). However, nontraditional relationships are often treated homogeneously in which the individuals involved in different types of relationship experience and cope with stigma in the similar manner (e.g., LeBlanc et al., 2015; Rosenthal et al., 2019). To investigate how different types of nontraditional relationships withstand stigma-related stressors, the current study proposes a relational stigma management framework that emphasizes communal orientated mindset in the couple-level stigma management and positive relationship maintenance. Incorporating the minority stress model and the theory of stigma communication management (SMC) into the theory of resilience and relational load (TRRL), this study bridges personal and relational as well as cognitive, communicative, and behavioral aspects of facilitating a resilient relationship under the stigma-related stress. In order to test the hypotheses in the proposed model, a web-based questionnaire was administrated and responses from 296 participants were analyzed. Participants were asked to think about the ways they handle stigma-related stress in relationships. They responded to measures of communal orientation, stigma management, relationship maintenance, personal health, resilience, and relational load. The model paths were analyzed with parallel mediation moderated by different types of stigma experiences using PROCESS macro in SPSS. The finding from this study illustrated mixed results regarding the role of stigma management and relationship maintenance in personal and relational health outcomes. Stigma management and relationship maintenance were shown to at least partially mediate communal orientation and relational outcomes; however, such mediation was not found for personal health. Individuals with one type of stigma versus compounded (i.e., individual and relationship) stigma moderated certain paths in the proposed model that contributed to their relational health outcomes. Results highlight the unique functions of how stigma orientation and maintenance behaviors can help withstand relational stress as well as promote distinct relational outcomes.
