description: 3D time-of-flight (ToF) imaging is used in a variety of applications such as augmented reality (AR), computer interfaces, robotics and autonomous systems. Single-photon avalanche diodes (SPADs) are one of the enabling technologies providing accurate depth data even over long ranges. By developing SPADs in array format with integrated processing combined with pulsed, flood-type illumination, high-speed 3D capture is possible. However, array sizes tend to be relatively small, limiting the lateral resolution of the resulting depth maps, and, consequently, the information that can be extracted from the image for applications such as object detection. In this paper, we demonstrate that these limitations can be overcome through the use of convolutional neural networks (CNNs) for high-performance object detection. We present outdoor results from a portable SPAD camera system that outputs 16-bin photon timing histograms with 64x32 spatial resolution. The results, obtained with exposure times down to 2 ms (equivalent to 500 FPS) and in signal-to-background (SBR) ratios as low as 0.05, point to the advantages of providing the CNN with full histogram data rather than point clouds alone. Alternatively, a combination of point cloud and active intensity data may be used as input, for a similar level of performance. In either case, the GPU-accelerated processing time is less than 1 ms per frame, leading to an overall latency (image acquisition plus processing) in the millisecond range, making the results relevant for safety-critical computer vision applications which would benefit from faster than human reaction times.

Type:— INDONESIA. Sulawesi, South Sulawesi: Latimojong, Palopo, Rantebala (cultivated at Bali Botanic Garden from living material collected in the wild), 16 May 2008, D.C. Thomas & W.H. Ardi 08-81 (holotype E!, isotype BO!).
Additional literature:— Hughes et al. (2018: 130) [photo plate].
Distribution:— Indonesia, endemic to Sulawesi, South Sulawesi: Latimojong Mountains (Fig. 1B).
Habitat:— Primary hill rain forest at ca. 1350 m elevation.
Provisional IUCN conservation assessment:— Critically Endangered (CR) B1ab(iii),B2ab(iii). This species is known from only a single collection at the eastern border of the Latimojong Forest Reserve. The collection is from a forest margin in close proximity to land converted for human habitation and agriculture. Exploration of various hill forest localities on the southern arm of Sulawesi including localities in the western Latimojong mountains have not resulted in any additional collections, and hence we must assume, until more extensive collection efforts reveal otherwise, that this species has a very restricted range. Because of the extremely small EOO and AOO in combination with observed disturbance and loss of forest habitat at the border of the Latimojong Forest Reserve, we assess this species as Critically Endangered.

Localities and specimens found: 8 − 2♀, 3♀ ov, 2♀ em, 1j; 25 − 25♀, 21♀ ov, 50♀ em, 95j; 26 − 51♀, 33♀ ov, 26♀ em, 116j; 27 −1j; 32 − 1♀, 1j.
Distribution and ecology. Ilyocryptus raridentatus s. str. was described from Australia in insufficient specification and has only recently been redescribed in detail (Kotov & Štifter 2006; Dadykin et al. 2024a). The currently known range of the species, in addition to Australia, covers a number of countries in Southeast and East Asia, penetrating north up to Korea, Japan and the Russian Far East (Kotov & Sanoamuang 2004b; Kotov & Štifter 2006; Kotov et al. 2011, 2012, 2024; Korovchinsky et al. 2021b; Choedchim & Maiphae 2023; Dadykin et al. 2023, 2024a). In Vietnam, this ilyocriptid was first recorded in the course of the present studies of the meiobenthos as I. cf. raridentatus (Gusakov et al. 2014, 2024).
This crustacean is a typical bottom dweller, like other representatives of the genus. It is found in various lentic and lotic water bodies (swamps, puddles, ponds, lakes, reservoirs, rivers, river floodplains, etc.) but its ecological preferences are still not fully understood (Kotov & Štifter 2006; Choedchim & Maiphae 2023; Dadykin et al. 2023, 2024a). In our material, I. raridentatus was found in the inshore biotopes of a natural lake, a sand quarry and two reservoirs. In qualitative samples from the open and plant-filled littoral of a small reservoir (Nos. 25, 26; see Appendix 1), on silt-clay sand, it was especially numerous.
Remarks. According to the latest revision (Dadykin et al. 2024a), some previously published finds of I. cf. sarsi Stingelin, 1913 and I. sordidus (Liévin, 1848) from East Asia might obviously also be attributed to I. raridentatus, but the results need additional verification, preferably by molecular methods.

description: We introduce and solve exactly a family of invariant 2x2 random matrices, depending on one parameter η, and we show that rotational invariance and real Dyson index βare not incompatible properties. The probability density for the entries contains a weight function and a multiple trace-trace interaction term, which corresponds to the representation of the Vandermonde-squared coupling on the basis of power sums. As a result, the effective Dyson index β_{eff} of the ensemble can take any real value in an interval. Two weight functions (Gaussian and non-Gaussian) are explored in detail and the connections with β-ensembles of Dumitriu-Edelman and the so-called Poisson-Wigner crossover for the level spacing are respectively highlighted. A curious spectral twinning between ensembles of different symmetry classes is unveiled. The proposed technical tool more generically allows for designing actual matrix models which i) are rotationally invariant; ii) have a real Dyson index β_{eff}; iii) have a pre-assigned confining potential or alternatively level-spacing profile. The analytical results have been checked through numerical simulations with an excellent agreement. Eventually, we discuss possible generalizations and further directions of research.

description: We investigate the gluonic structure of nuclei within a mean-field model of nuclear structure based upon the modification of the structure of a bound nucleon, with the nucleon described by the Nambu--Jona-Lasinio model. This approach has been shown to reproduce the European Muon Collaboration (EMC) effect, involving the ratio of the spin-independent structure functions of a heavier nucleus to that of the deuteron. It also predicts a significant nuclear modification for the spin structure functions, known as the polarized EMC effect. Here we report sizeable nuclear modifications of the gluon distributions (a "gluon EMC effect") for the ratios of both the unpolarized and polarized gluon distributions in nuclear matter to those of a free nucleon.

description: La mise à jour de l’analyse probabiliste de l’aléa sismique en Roumanie est nécessaire pour la règlementation parasismique nationale et à cause de l’impact régional de la source sismique de profondeur intermédiaire Vrancea. Les recherches sur l’aléa sismique européen montrent des valeurs élevées de l’accélération du sol sur des larges surfaces qui dépassent les frontières du pays. Les principes de l’analyse probabiliste de l’aléa sismique ont été énoncés dans le célèbre article de Cornell (1968). La méthodologie actuelle intègre les incertitudes aléatoires et épistémiques. L’article ne se concentre pas sur les aspects sismologiques, mais sur la présentation de l’utilisation des statistiques et probabilités dans l’analyse : traitement des données des catalogues sismiques, densité de probabilité des magnitudes, occurrence des évènements sismiques, etc. Une équation de prédiction des valeurs spectrales des mouvements sismiques caractéristiques à la source intermédiaire de Vrancea est décrite avec des éléments sur l’analyse des résidus. Les résultats sont présentés sous la forme de courbe d’aléa sismique au site et de carte de zonage probabiliste.

description: La durée de vie résiduelle pourrait être un indicateur important pour la planification de l’inspection et de la maintenance des structures se dégradant. Dans ce travail, nous proposons une approche pour l’estimation et l’actualisation de la durée de vie résiduelle d’un pipeline soumis à la dégradation par corrosion. Cette approche s’appuie sur un modèle prédictif modélisant la perte d’épaisseur par corrosion pour estimer la durée de fonctionnement avant la défaillance. Afin de prendre en considération les éventuelles évolutions des facteurs agissant sur le processus de dégradation (i.e. corrosion), l’approche proposée permet la mise à jour de la durée de vie résiduelle lorsque de nouvelles mesures de dégradation sont disponibles.

description: La gestion de l'intégrité des pipelines souffre souvent de plusieurs formes de dégradation qui varient dans le temps et dans l'espace, principalement l’encrassement (dépôts et tartre) et les pertes de métal (corrosion). Dans ce cadre, le présent travail a pour objet de développer une méthode probabiliste pour évaluer la fiabilité du système de canalisation en fonction du temps, en tenant compte de l’intersection des deux modes de défaillance courants : le colmatage et les fuites des tubes dues à l’encrassement et à la corrosion localisée respectivement. La décomposition de Karhunen-Loève a été utilisée pour modéliser la variabilité spatiale de la corrosion, des contraintes résiduelles et de l’encrassement dans les différentes zones irrégulières (Segments, coudes de tuyau avec brides et joints soudés). Dans ce travail, le pipeline est modélisé par un système en série et les probabilités de défaillance du système sont calculées par la méthode de Monte-Carlo. La démarche méthodologique proposée est appliqué à un pipeline enterré, afin de montrer les effets des principaux paramètres du système.

Year: 2010

description: This thesis examines Chinese business activity in Vancouver, British Columbia between 1886 and 1914 as one avenue of immigrant adjustment. Government documents and reports, as well as business records from local Chinese merchant operations, were consulted. Chinese migrants to Canada brought with them business skills and concepts that were readily applied to economic opportunities arising inside and outside of Chinatown. The Chinese conducted a wide variety of businesses, revealing that the host society was most receptive to the Chinese.presence.in the commercial sphere. The viability of business activities reassured immigrants that their ambitions to earn money overseas were achievable despite persi.s.tent anti-Asian hostility in the general environment. Old and new world elements thus aided the survival and integration experience of the Chinese in Vancouver.

description: We propose a set-valued framework for the well-posedness of birth-and-growth process. Our birth-and-growth model is rigorously defined as a suitable combination, involving Minkowski sum and Aumann integral, of two very general set-valued processes representing nucleation and growth respectively. The simplicity of the used geometrical approach leads us to avoid problems arising by an analytical definition of the front growth such as boundary regularities. In this framework, growth is generally anisotropic and, according to a mesoscale point of view, it is not local, i.e. for a fixed time instant, growth is the same at each space point.

description: Scalable substitutional doping of two-dimensional (2D) transition metal dichalcogenides (TMDCs) is a prerequisite to developing next-generation logic and memory devices based on 2D materials. To date, doping efforts are still nascent. Here, we report scalable growth and vanadium (V) doping of 2D WSe2 at front-end-of-line (FEOL) and back-end-of-line (BEOL) compatible temperatures of 800 °C and 400 °C, respectively. A combination of experimental and theoretical studies confirm that vanadium atoms substitutionally replace tungsten in WSe2, which results in p-type doping via the introduction of discrete defect levels that lie close to the valence band maxima. The p-type nature of the V dopants is further verified by constructed field-effect transistors, where hole conduction becomes dominant with increasing vanadium concentration. Hence, our study presents a method to precisely control the density of intentionally introduced impurities, which is indispensable in the production of electronic-grade wafer-scale extrinsic 2D semiconductors.

description: Ce papier présente une analyse de l’influence des modèles d’efficacité de la maintenance sur l’optimisation des révisions des systèmes réparables. Nous avons utilisé les modèles d’efficacité de maintenance hybride généré d’une combinaison des deux autres modèles à savoir modèle de réduction d'âge virtuel et réduction d'intensité. Nous avons considéré la politique de maintenance préventive périodique avec réparation minimale à la défaillance. Suivant cette politique, le système est soumis à des révisions partielles périodiques, avec réparations minimales pour les défaillances survenant entre les révisions. Le cycle se répète jusqu'à ce que le système soit renouvelé. La minimisation du coût par unité de temps a permis de trouver les périodicités et leur nombre, d’une façon optimale. Pour l’optimisation, nous avons eu recours à la fonction fminsearch de MATLAB. Les résultats ont été comparés à ceux obtenus par les deux approches : réduction d’âge et réduction d’intensité, et ont montré que le modèle de réduction d’âge peut conduire à des économies de coûts significatives.

description: Not having access to compact and meaningful representations is known to significantly increase the complexity of reinforcement learning (RL). For this reason, it can be useful to perform state representation learning (SRL) before tackling RL tasks. However, obtaining a good state representation can only be done if a large diversity of transitions is observed, which can require a difficult exploration, especially if the environment is initially reward-free. To solve the problems of exploration and SRL in parallel, we propose a new approach called XSRL (eXploratory State Representation Learning). On one hand, it jointly learns compact state representations and a state transition estimator which is used to remove unexploitable information from the representations. On the other hand, it continuously trains an inverse model, and adds to the prediction error of this model a $k$-step learning progress bonus to form the maximization objective of a discovery policy. This results in a policy that seeks complex transitions from which the trained models can effectively learn. Our experimental results show that the approach leads to efficient exploration in challenging environments with image observations, and to state representations that significantly accelerate learning in RL tasks.

description: Whispering-gallery mode resonators host multiple trapped narrowband circulating optical resonances that find applications in quantum electrodynamics, optomechanics, and sensing. However, the spherical symmetry and low field leakage of dielectric microspheres make it difficult to probe their high-quality optical modes using far-field radiation. Even so, local field enhancement from metallic nanoparticles (MNPs) coupled to the resonators can interface the optical far-field and the bounded cavity modes. In this work, we study the interaction between whispering-gallery modes and MNP surface plasmons with nanometric spatial resolution by using electron-beam spectroscopies in a scanning transmission electron microscope. We show that gallery modes are induced over a selective spectral range of the nanoparticle plasmons, and additionally, their polarization can be controlled by the induced dipole moment of the MNP. Our study demonstrates a viable mechanism to effectively excite high-quality-factor whispering-gallery modes and holds potential for applications in optical sensing and light manipulation.

description: Spin-orbital entanglement in the ground state of a one-dimensional SU(2)$\otimes$SU(2) spin-orbital model is analyzed using exact diagonalization of finite chains. For $S=1/2$ spins and $T=1/2$ pseudospins one finds that the quantum entanglement is similar at the SU(4) symmetry point and in the spin-orbital valence bond state. We also show that quantum transitions in spin-orbital models turn out to be continuous under certain circumstances, in constrast to the discontinuous transitions in spin models with SU(2) symmetry.

The historical geography of book markets in China : a case study of Liulichang
Creators: name: Yee, Francis Lok-Wing
Publisher: name: University of British Columbia

description: Scholars have long recognized the significance of printing in the dissemination of knowledge, promotion of new ideas and consequently as a force of social and economic change. However, the critical role played by the bookshops in the development and diffusion of printing has rarely been studied. In both Europe and China, bookstores produced and distributed a wide range of publications including popular literature, religious works, practical manuals for the common people as well as literary works, Classics and standard texts for the scholars and students. Bookstores thus, on one hand, promoted popular literacy amongst the masses but also, on the other hand, upheld the orthodox ideology by circulating the government-approved Classics and texts to the literate elites. In their long history of development, bookstores and book markets in China experienced changes not only geographically but also functionally. In the Song and Yuan periods, the concentration of urban population, together with the expansion ©f commercial and cultural activities, encouraged the growth of book production and marketing in regional metropolitan market centres. Kaifeng, Hangzhou and Chengdu clearly emerged as the major regional book markets in this period. In the Ming and Qing periods, a relatively well-integrated national marketing system developed. Inter-regional book trade also expanded in this period with Beijing at the uppermost end of the marketing hierarchy. The expansion of the book marketing system seems to be at least partially linked to the increasing importance attached to the civil service examination system. An overlap between the administrative and commercial functions of the late imperial cities is clear in this case. It is one main thesis of this study that the origins and development of book markets in China not only reflected, but also contributed to the expansion of the traditional regional, inter-regional, and eventually empire-wide urban market economy of imperial China. Moreover, they became a principal medium for the rise and dominance of the scholar-official elites of imperial China, and — in this sense — played a major role in shaping the character of the principal component of the urban social fabric of Confucian China. A study of book printing and marketing in imperial China is, in short, thus also a study in the changing role of the city and its dominant class — the urban gentry. And, whereas this becomes especially evident in urban cores of the late imperial period, it is no where more clear than in the singularly important case of the book markets of the imperial capital itself, Beijing, and in the main book market of old Beijing, Liulichang.

description: We calculate exactly the entanglement content of magnon excited states in the integrable spin-1/2 XXX and XXZ chains in the scaling limit. In particular, we show that as far as the number of excited magnons with respect to the size of the system is small one can decompose the entanglement content, in the scaling limit, to the sum of the entanglement of particular excited states of free fermionic or bosonic theories. In addition we conjecture that the entanglement content of the generic translational invariant free fermionic and bosonic Hamiltonians can be also classified, in the scaling limit, with respect to the entanglement content of the fermionic and bosonic chains with the number operator as the Hamiltonian in certain circumstances. Our results effectively classify the entanglement content of wide range of integrable spin chains in the scaling limit.

A resolution criterion based on characteristic timescales for MHD simulations of molecular clouds

description: We investigate the effect of numerical magnetic diffusion in magnetohydrodynamic simulations of magnetically supported molecular clouds. To this end, we have performed numerical studies on adaptive mesh isothermal simulations of marginally sub-critical molecular clouds. We find that simulations with low and intermediate resolutions collapse, contrary to what is theoretically expected. However, the simulation with the highest numerical resolution oscillates around an equilibrium state without collapsing. In order to quantify the numerical diffusion of the magnetic field, we ran a second suit of current-sheet simulations in which the numerical magnetic diffusion coefficient can be directly measured, and computed the corresponding diffusion times at various numerical resolutions. On this basis, we propose a criterion for the resolution of magnetic fields in MHD simulations based on requiring that the diffusion time to be larger than the characteristic timescale of the physical process responsible for the dynamic evolution of the structure.

description: Linear cases of Bragg-Hawthorne equation for steady axisymmetric incompressible ideal flows are systematically discussed. The equation is converted to a more convenient form in a spherical coordinate system. A new vorticity decomposition is derived. General solutions for 16 linear cases of the equation are obtained. These solutions can be specified to gain new analytical vortex flows, as examples in the paper demonstrate. A lot of well_known solutions like potential flow past a sphere, Hill's vortex with and without swirl, are included and extended in these solutions. Special relations between some vortex flows are also revealed when exploring or comparing related solutions.

description: In this paper, we abstract a kind of stochastic processes from evolving processes of growing networks, this process is called growing network Markov chains. Thus the existence and the formulas of degree distribution are transformed to the corresponding problems of growing network Markov chains. First we investigate the growing network Markov chains, and obtain the condition in which the steady degree distribution exists and get its exact formulas. Then we apply it to various growing networks. With this method, we get a rigorous, exact and unified solution of the steady degree distribution for growing networks.

An analysis of two approaches to teaching used by grade 8 mathematics teachers
Creators: name: Tam, Rosita Tseng
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of the study was to perform an analysis of two approaches to teaching used by Grade 8 mathematics teachers in British Columbia. A comparison was made in the orientation to concrete and abstract approaches. The major question addressed in the study was: Were teacher practices in accordance with the theory of instruction proposed by several authors, in which it is recommended that concepts be presented using manipulative materials, pictures, or diagrams, and then through abstract presentations with symbols? To address this question, an analysis was made of the data collected from approximately 100 mathematics teachers who took part in the Second International Mathematics Study (SIMS) during the 1980-81 school year. The instruments used to collect the data were a set of five topic-specific questionnaires on classroom processes. The items in these questionnaires related to many aspects of classroom practice. This study was concerned with those items that were constructed to collect information on methods used in presenting certain concepts and skills in the Grade 8 mathematics curriculum. Since the nature of the data was not known prior to analysis, the study was designed to explore the nature of the data so that valid comparisons could be made on the concrete-abstract variable. Several data processing procedures were used. These procedures included the categorization of items by a panel of experts; the scoring of items; the preliminary analysis to investigate the justifiability of aggregation of item scores; and the calculation of concrete, abstract, and difference scores for all the teachers. Exploratory data analysis techniques were then used to compare the teachers' choice between concrete and abstract approaches. The results of the analysis seemed to indicate that teachers were abstractly-oriented in teaching most of the skills and concepts included in the study. In their teaching of three new concepts and skills in the Grade 8 curriculum, mathematics teachers were concretely-oriented in their teaching of one concept only. This finding led to the conclusion that teacher practices were not in accordance with the theory of instruction which states that new concepts and skills in mathematics should be initially taught using concretely-oriented approaches.

description: Combining mean-field and renormalization group analyses, here we unveil the nature of recently observed superconductivity and parent metallic states in chemically doped rhombohedral trilayer graphene, subject to external electric displacement fields ($D$) [H. Zhou, \emph{et al.}, Nature (London) {\bf 598}, 434 (2021)]. We argue that close to the charge neutrality, on site Hubbard repulsion favors layer antiferromagnet, which when combined with the $D$-field induced layer polarization, produces a spin-polarized, but valley-unpolarized half-metal, conducive to the nucleation of spin-triplet $f$-wave pairing (SC2). At larger doping valence bond order emerges as a prominent candidate for isospin coherent paramagent, boosting condensation of spin-singlet Cooper pairs in the $s$-wave channel (SC1), manifesting a "selection rule" among competing orders. Responses of these paired states to displacement and in-plane magnetic fields show qualitative similarities with experimental observation. With the onset of the quantum anomalous Hall order, the valley degeneracy of half-metal gets lifted, forming a quarter-metal at lower doping [H. Zhou, \emph{et al.}, Nature (London) {\bf 598}, 429 (2021)].
