description: We construct a canonical noncommutative spectral triple for every oriented closed Riemannian manifold, which represents the fundamental class in the twisted K-homology of the manifold. This so-called "projective spectral triple" is Morita equivalent to the well-known commutative spin spectral triple provided that the manifold is spin-c. We give an explicit local formula for the twisted Chern character for K-theories twisted with torsion classes, and with this formula we show that the twisted Chern character of the projective spectral triple is identical to the Poincaré dual of the A-hat genus of the manifold.

Recording and documenting music for the Heritage Inventory of Suai-Camenaça
Creators: name: Pettigrew, Aaron
Publisher: name: University of British Columbia
Year: 2020

description: From 2014-2016, the Timorese NGO Timor Aid conducted a multi-disciplinary research project in Timor-Leste to “[document] the cultural heritage of the peoples of Suai-Camenaça and surrounds who will be affected by the Tasi Mane Petroleum Infrastructure Project” (Timor Aid n.d.), scheduled to take place between 2011-2030 along the south coast (República Democrática de Timor-Leste 2011, 141). The Heritage Inventory sought to “document local culture and traditions including language, music, cultural geography, biodiversity, and textiles... before these practices are disrupted, changed, or lost as a result of this mega-infrastructure project” (Timor Aid n.d.). In 2015, ethnomusicologist Philip Yampolsky led a small team of music researchers who traveled to Suai-Camenaça to document traditional music for the Heritage Inventory. The team visited several musical events over a period of 58 days to create audio and video recordings and to create written documentation from direct observation. This thesis presents the research and findings of the music research team. It includes an overview of the history and geography of Timor-Leste and a brief introduction to the scope of the Tasi Mane Petroleum Infrastructure Development Project. A review of previous music research conducted in Timor-Leste places the work of the music research team in its scholarly context. Findings are presented alongside detailed documentation of the research methodology, and they include several musical practices and genres that had not previously been documented in scholarly work. The author uses Catherine Grant’s Music Vitality and Endangerment Framework (Grant 2014) to analyze the findings and create a preliminary assessment of the vitality of traditional musical practices in Suai-Camenaça, and this assessment is discussed in the context of broader scholarly debate concerning endangerment and preservation in ethnomusicological research.
Analysis of the phase transition for the Ising model on the frustrated square lattice

description: We analyze the phase transition of the frustrated $J_1$-$J_2$ Ising model with antiferromagnetic nearest- and strong next-nearest neighbor interactions on the square lattice. Using extensive Monte Carlo simulations we show that the nature of the phase transition for $1/2 < J_2/J_1 \lesssim 1$ is not of the weakly universal type -- as commonly believed -- but we conclude from the clearly doubly peaked structure of the energy histograms that the transition is of weak first order. Motivated by these results, we analyze the phase transitions via field-theoretic methods; i.e., we calculate the central charge of the underlying field theory via transfer-matrix techniques and present, furthermore, a field-theoretic discussion on the phase-transition behavior of the model. Starting from the conformally invariant fixed point of two decoupled critical Ising models ($J_1 = 0$), we calculate the effect of the nearest neighbor coupling term perturbatively using operator product expansions. As an effective action we obtain the Ashkin-Teller model.

description: We estimate and compare technical efficiency (TE), technology gap ratio (TGR), and meta-technical efficiency (MTE) of sorghum production between three groups of plots which have been classified on the basis of the type of land property rights held by farmers (formal land rights, customary land rights, and no land rights). Nationally representative household data collected in 2011 in rural Burkina Faso are analyzed. The stochastic meta-frontier approach is followed to address the heterogeneity of the technologies used by sorghum farmers. The TE and MTE are estimated at 69% and 51.96%, respectively. It is found that the group of plots held with formal land rights has the higher MTE and TGR, implying that farmers use the best technology on these plots where they are more efficient. This evidence may highlight the positive effect of land property rights security in the adoption of better farm management practices stimulating production efficiency. The results imply that sorghum farmers have the possibility of increasing their level of production by 31% with the same resources. We argue that securing land property rights by a well undertaken formalization process is one of the factors helping to stimulate this possibility.
Sparsity Domain Smoothing Based Thresholding Recovery Method for OFDM Sparse Channel Estimation

description: Due to the ever increasing data rate demand of beyond 5G networks and considering the wide range of Orthogonal Frequency Division Multipllexing (OFDM) technique in cellular systems, it is critical to reduce pilot overhead of OFDM systems in order to increase data rate of such systems. Due to sparsity of multipath channels, sparse recovery methods can be exploited to reduce pilot overhead. OFDM pilots are utilized as random samples for channel impulse response estimation. We propose a three-step sparsity recovery algorithm which is based on sparsity domain smoothing. Time domain residue computation, sparsity domain smoothing, and adaptive thresholding sparsifying are the three-steps of the proposed scheme. To the best of our knowledge, the proposed sparsity domain smoothing based thresholding recovery method known as SDS-IMAT has not been used for OFDM sparse channel estimation in the literature. Pilot locations are also derived based on the minimization of the measurement matrix coherence. Numerical results verify that the performance of the proposed scheme outperforms other existing thresholding and greedy recovery methods and has a near-optimal performance. The effectiveness of the proposed scheme is shown in terms of mean square error and bit error rate.

description: We present a unified approach to constrained implicit Lagrangian and Hamiltonian systems based on the introduced concept of Dirac algebroid. The latter is a certain almost Dirac structure associated with the Courant algebroid on the dual $E^\ast$ to a vector bundle $E$. If this almost Dirac structure is integrable (Dirac), we speak about a Dirac-Lie algebroid. The bundle $E$ plays the role of the bundle of kinematic configurations (quasi-velocities), while the bundle $E^\ast$ - the role of the phase space. This setting is totally intrinsic and does not distinguish between regular and singular Lagrangians. The constraints are part of the framework, so the general approach does not change when nonholonomic constraints are imposed, and produces the (implicit) Euler-Lagrange and Hamilton equations in an elegant geometric way. The scheme includes all important cases of Lagrangian and Hamiltonian systems, no matter if they are with or without constraints, autonomous or non-autonomous etc., as well as their reductions; in particular, constrained systems on Lie algebroids. we prove also some basic facts about the geometry of Dirac and Dirac-Lie algebroids.

description: We present the UrbanBIS benchmark for large-scale 3D urban understanding, supporting practical urban-level semantic and building-level instance segmentation. UrbanBIS comprises six real urban scenes, with 2.5 billion points, covering a vast area of 10.78 square kilometers and 3,370 buildings, captured by 113,346 views of aerial photogrammetry. Particularly, UrbanBIS provides not only semantic-level annotations on a rich set of urban objects, including buildings, vehicles, vegetation, roads, and bridges, but also instance-level annotations on the buildings. Further, UrbanBIS is the first 3D dataset that introduces fine-grained building sub-categories, considering a wide variety of shapes for different building types. Besides, we propose B-Seg, a building instance segmentation method to establish UrbanBIS. B-Seg adopts an end-to-end framework with a simple yet effective strategy for handling large-scale point clouds. Compared with mainstream methods, B-Seg achieves better accuracy with faster inference speed on UrbanBIS. In addition to the carefully-annotated point clouds, UrbanBIS provides high-resolution aerial-acquisition photos and high-quality large-scale 3D reconstruction models, which shall facilitate a wide range of studies such as multi-view stereo, urban LOD generation, aerial path planning, autonomous navigation, road network extraction, and so on, thus serving as an important platform for many intelligent city applications.

description: We provide a psychometric-grounded exposition of bias and fairness as applied to a typical machine learning pipeline for affective computing. We expand on an interpersonal communication framework to elucidate how to identify sources of bias that may arise in the process of inferring human emotions and other psychological constructs from observed behavior. Various methods and metrics for measuring fairness and bias are discussed along with pertinent implications within the United States legal context. We illustrate how to measure some types of bias and fairness in a case study involving automatic personality and hireability inference from multimodal data collected in video interviews for mock job applications. We encourage affective computing researchers and practitioners to encapsulate bias and fairness in their research processes and products and to consider their role, agency, and responsibility in promoting equitable and just systems.

description: Glycoproteins formed by covalent links between oligosaccharide and polypeptides are abundant in various food sources. They are less sensitivity to gastrointestinal enzymes, and hence many of them undergo fermentation in the colon by microorganisms. Therefore, the confer various health benefits on the intestinal ecosystem. However, the current understanding of the effect of glycoproteins on intestinal microorganisms and gut health is limited. This is probably due to their heterogeneous structures and complex metabolic programming patterns. The structure and biological activities of glycoproteins and their microbial metabolites were summarized in this review. The metabolic pathways activated by intestinal bacteria were then discussed in relation to their potential benefits on gut health. Food-derived glycoproteins and their metabolites improve gut health by regulating the intestinal bacteria and improving intestinal barrier function, thereby amplifying immune response. The data reviewed here show that food-derived glycoproteins are promising candidates for preventing various gastrointestinal diseases. Further studies should explore the interaction mechanisms between intestinal microorganisms and host metabolites.

Cities and Local Governments: International Development from Below?

subject: 300 Sozialwissenschaften::300 Sozialwissenschaften, Soziologie::300 Sozialwissenschaften

description: Cities and local governments have become both important sites for international development as well as actors which aspire to shape the practice in this field. This paper retraces the emergence of cities and local governments as having this dual character, in order to provide the ground for a more forward-looking deliberation on some of the emerging themes on the role of cities in and for international law and development today. We see in particular a friction between two seemingly competing and broader understandings of global development, in both of which cities play a prominent role: the SDGs as adopted in 2015, and China’s Belt and Road Initiative (BRI). The SDGs are the most important multilateral articulation of ideas of development today. To this extent, they are considerably shaped by the long shadow of the post-Cold War era and the shifting priorities of influential actors like the United States, the European Union, but also increasingly vocal states from the ‘Global South’. The BRI follows a different idea of international development, built around the notions of non-interference and ‘win-win cooperation.’ What unites these two blueprints for global development is that international law, as traditionally understood, does not seem to take center stage. Or rather, we wish to expound, it may be a new type of international law which emerges from these global constellations of international development which comes not only, but also from below.
The Effectiveness of The Road Traffic Liability System in China? A Law and Economics Perspective
Creators: name: Yan, Yu
name: Faure, Michael
Publisher: name: Columbia Journal of Asian Law
Year: 2020

description: This article analyses the effectiveness of the Chinese road traffic liability system in terms of both deterrence and compensation. We utilize the neo-classical economic model of accidents to assess the key features of the system, such as the basis of liability, the level of the benefits, the impacts of liability insurance and regulation, as well as the capacity of risk-spreading. The analysis shows that the road traffic liability system in China can only achieve partial deterrence. Under-compensation and insufficient risk-spreading seem to be serious problems, at least in the economically underdeveloped regions. Therefore, we propose several legislative changes that the policymaker could implement to improve the system.

The Shape of Jupiter and Saturn Based on Atmospheric Dynamics, Radio Occultations and Gravity Measurements

description: The shape of the two gas giants, Jupiter and Saturn, is determined primarily by their rotation rate, and interior density distribution. It is also affected by their zonal winds, causing an anomaly of O(10 km) at low latitudes. However, uncertainties in the observed cloud-level wind and the polar radius, translate to an uncertainty in the shape with the same order of magnitude. The Juno (Jupiter) and Cassini (Saturn) missions gave unprecedented accurate gravity measurements, constraining better the uncertainty in the wind structure. Using an accurate shape calculation, and a joint optimization, given both gravity and radio-occultation measurements, we calculate the possible range of dynamical height for both planets. We find that for Saturn there is an excellent match to the radio-occultation measurements, while at Jupiter such a match is not achieved. This may point to deviations from a barotropic flow above the cloud level, which might be tested with the forthcoming radio-occultation measurements by Juno.

Subjects: subject: Mathematical Software (cs.MS)
subject: FOS: Computer and information sciences

description: This paper proposes a type of pseudorandom number generator, Mersenne Twister for Graphic Processor (MTGP), for efficient generation on graphic processessing units (GPUs). MTGP supports large state sizes such as 11213 bits, and uses the high parallelism of GPUs in computing many steps of the recursion in parallel. The second proposal is a parameter-set generator for MTGP, named MTGP Dynamic Creator (MTGPDC). MT- GPDC creates up to 2^32 distinct parameter sets which generate sequences with high-dimensional uniformity. This facility is suitable for a large grid of GPUs where each GPU requires separate random number streams. MTGP is based on linear recursion over the two-element field, and has better high-dimensional equidistribution than the Mersenne Twister pseudorandom number generator.

description: The overarching goal of NCSS 2012 was to strengthen the evidence base to guide policies and programs aimed at
improving the wellbeing of the urban poor. Specifically, the survey pursued three main objectives:

1. To document current population and health challenges among the residents of Nairobi's informal settlements.

2. To take stock of the changes (or the lack thereof) in health outcomes, livelihood conditions and demographic
   behavior among slum dwellers in Nairobi, ten years after the NCSS 2000.

3. To compare indicators among slum dwellers in Nairobi to other urban population sub-groups and rural dwellers in
   Kenya.

description: Il passaggio dalla scuola elementare alla scuola media è una tappa importante che caratterizza la vita dei ragazzi, poiché essi si apprestano a entrare in una fase di sviluppo nella quale si vanno a porre le basi per l’identità adulta. Per questo motivo è importante che gli allievi possano esprimersi e raccontarsi facendo emergere eventuali preoccupazioni o domande. Nella presente tesi di bachelor si è voluto permettere ai ragazzi, in alcuni casi attraverso un linguaggio metaforico, di esprimere i loro timori riguardo al cambiamento che li attende. In seguito gli allievi hanno individuato le proprie identità competenti, strumento d’indagine che ha consentito loro di scoprire e valorizzare le risorse necessarie per affrontare al meglio l’inizio della scuola media. Le informazioni e i dati raccolti grazie alle produzioni dei bambini e agli scambi verbali, sono stati analizzati qualitativamente portando alla luce le tipologie di paure espresse e le categorie di identità competenti individuate. Grazie allo studio si è potuto concludere che gli allievi hanno apprezzato e approfittato della possibilità di espressione a loro concessa e sono riusciti ad individuare delle competenze, sia in loro che nei propri compagni, utili ad intraprendere il viaggio nel nuovo ordine scolastico.

description: Hankel operators with anti-holomorphic symbols are studied for a large class of weighted Fock spaces on $\cn$. The weights defining these Hilbert spaces are radial and subject to a mild smoothness condition. In addition, it is assumed that the weights decay at least as fast as the classical Gaussian weight. The main result of the paper says that a Hankel operator on such a Fock space is bounded if and only if the symbol belongs to a certain BMOA space, defined via the Berezin transform. The latter space coincides with a corresponding Bloch space which is defined by means of the Bergman metric. This characterization of boundedness relies on certain precise estimates for the Bergman kernel and the Bergman metric. Characterizations of compact Hankel operators and Schatten class Hankel operators are also given. In the latter case, results on Carleson measures and Toeplitz operators along with Hörmander's $L^2$ estimates for the $\bar{\partial}$ operator are key ingredients in the proof.

description: This study examines physical activity within inclusively designed play environments for children with and without disabilities. The purpose of this study is to determine to what extent children in the third grade with and without disabilities differ in physical activity across various behavior settings of an inclusively designed play environment. Of the 50 third-grade students, 34 participated in eight weeks of observations conducted during lunch recess. Accelerometers and GPS units were utilized to collect data during the observations. The majority of settings on this playground were identified as inclusive. Children with disabilities didn’t engage in organized games as often as the children without disabilities; they tended to play by themselves more often. Neither the children with disabilities nor the children without them seem to have a strong preference for one setting on the playground versus another. The study concludes that inclusively designed playgrounds reduce barriers for children with disabilities and create an environment that is accessible and beneficial for all children.

description: Given a symplectic cohomology class of degree 1, we define the notion of an equivariant Lagrangian submanifold. The Floer cohomology of equivariant Lagrangian submanifolds has a natural endomorphism, which induces a grading by generalized eigenspaces. Taking Euler characteristics with respect to the induced grading yields a deformation of the intersection number. Dehn twists act naturally on equivariant Lagrangians. Cotangent bundles and Lefschetz fibrations give fully computable examples. A key step in computations is to impose the "dilation" condition stipulating that the BV operator applied to the symplectic cohomology class gives the identity. Equivariant Lagrangians mirror equivariant objects of the derived category of coherent sheaves.

description: We present an improved dynamical model of the X-ray binary and microquasar XTE J1550-564 based on new moderate-resolution optical spectroscopy and near-infrared photometry. By combining our new radial velocity measurements with previous measurements obtained 2001 May at the 8.2m VLT and with light curves, we find an orbital period of P=1.5420333 +/- 0.0000024 days and a radial velocity semiamplitude of K_2=363.14 +/- 5.97$ km/sec, which together imply an optical mass function of f(M)=7.65 +/- 0.38 solar masses. We find that the projected rotational velocity of the secondary star is 55 +/- 5 km/sec, which implies a very extreme mass ratio of Q=M/M_2=30. Using a model of a Roche lobe-filling star and an azimuthally symmetric accretion disk, we fit simultaneously optical light curves from 2001, near-infrared light curves from 2008 and all of the radial velocity measurements to derive system parameters. We find an inclination of 74.7 +/- 3.8 deg and component masses of M_2=0.30 +/- 0.07 solar masses and M=9.10 +/- 0.61 solar masses for the secondary star and black hole, respectively. The radius of the secondary star for the adopted model is 1.75 +/- 0.12 solar radii. Using this radius, the average K_S magnitude, and an extinction of A_K=0.507 +/- 0.050 mag, we find a distance of 4.38^{+0.58}_{-0.41} kpc, which is in good agreement with a recent distance estimate based on HI absorption lines (abstract shortened).

description: BackgroundUnderstanding young children's eating behaviours is vital to childhood obesity prevention. However, the widely used Children's Eating Behaviour Questionnaire (CEBQ) has not been validated in Chinese young children. Thus, the present study aimed to assess the validity of the CEBQ in a Chinese urban sample of preschool children.MethodsParticipants included 389 mothers with preschool children residing in Beijing, China. Confirmatory factor analysis was conducted, and measurement invariance between child genders was evaluated.ResultsThe modified 8-factor structure of the CEBQ exhibited acceptable model fit in our sample, and no measurement bias against any gender was observed. The associations between the CEBQ factors and child age showed that desire to drink, emotional overeating, and emotional undereating significantly decreased with age, but food responsiveness increased with age. The relation between child BMI and the CEBQ factors provided convergent validity for the CEBQ.ConclusionsOur study supported the validity of the CEBQ as a measurement tool for examining preschool children's eating behaviours in a Chinese urban sample.

description: The density functional theory (DFT) is used in a study of point defects on both UN (001) surface and sub-surface layers. We compare results for slabs of different thicknesses (both perfect and containing nitrogen or uranium vacancies) with a full geometry, electronic and spin density optimization. The electronic charge density re-distribution, density of states, magnetic moments of atoms as well as local atomic displacements around defects are carefully analyzed. It is predicted that the vacancies are formed easier on the surface whereas the sub-surface layer does not differ signifincantly from the central one in the slab.

Η εργασία χωρίζεται σε δύο μέρη. Στο πρώτο, γίνεται εκτενής αναφορά του τρόπου παραγωγής, των χαρακτηριστικών, του σχεδιασμού και των καταπονήσεων στις οποίες υποβάλλονται τα λεπτότοιχα χαλύβδινα μέλη. Ιδιαίτερη έμφαση δίνεται στη μελέτη των μορφών λυγισμού από τις οποίες καταπονούνται τα λεπτότοιχα στοιχεία, σύμφωνα πάντα με το μέρος 1-3 του Ευρωκώδικα 3. Επιπλέον, όσον αφορά τις συνδέσεις, περιγράφονται οι διάφοροι τρόποι με τους οποίους πραγματοποιούνται, οι μορφές αστοχίας τους, όπως επίσης και η διαστασιολόγηση με βάση το μέρος 1-3 του Ευρωκώδικα 3. Στο δεύτερο μέρος, δημιουργήθηκαν με τη χρήση του προγράμματος Excel Microsoft Office, υπολογιστικά φύλλα με σκοπό τον υπολογισμό της επάρκειας ή όχι διάφορων περιπτώσεων μελών και συνδέσεων. Πιο αναλυτικά, στο πρώτο παράδειγμα γίνεται ο έλεγχος επάρκειας μιας αμφιέριστης τεγίδας διατομής C, υπό τη δράση ανεμοπίεσης. Στο δεύτερο, παρουσιάζεται ο έλεγχος ενός διμελούς υποστυλώματος από διατομές C, καταπονούμενο από αξονική δύναμη αλλά και από γραμμικά μεταβαλλόμενες ροπές. Συμπληρωματικά, προκειμένου να ελεγχθεί η επάρκεια των συνδέσεων των λεπτότοιχων διατομών ψυχρής έλασης, δημιουργήθηκαν ξανά με τη χρήση του προγράμματος Excel Microsoft Office, τρία παραδείγματα για τον εκάστοτε τρόπο σύνδεσης. Για τα μηχανικά μέσα, εξετάστηκε η επάρκεια των κοχλιών, των πριτσινιών και των αυτοεμπηγνυόμενων βιδών με διαφορετικά συνδεόμενα μέλη σεκάθε περίπτωση, ενώ για τις συγκολλήσεις ελέγχθηκαν οι συνδέσεις σημειακών ραφών, ραφών οπών και εξωραφών σε συνδεόμενα ελάσματα. Οι υπολογισμοί των αντοχών και των γεωμετρικών στοιχείων, τόσο των διατομών όσο και των συνδέσεων, γίνονται βασιζόμενοι στα πρότυπα του Ευρωκώδικα 3 και ειδικότερα στα μέρη 1-1 «Γενικοί κανόνες και κανόνες για κτίρια», 1-3 «Γενικοί κανόνες – Συμπληρωματικοί κανόνες για μέλη και φύλλα ψυχρής έλασης» και 1-5 «Δομικά στοιχεία και επίπεδα ελάσματα». Τέλος, μετά το πέρας των ελέγχων αναφέρονται υπό μορφή συμπερασμάτων τα αποτελέσματα των παραδειγμάτων.
Influence of high pressure on the remarkable itinerant electron behaviour in Y$_{0.7}$Er$_{0.3}$Fe$_2$D$_{4.2}$ compounds

description: Monoclinic Y$_{0.7}$Er$_{0.3}$Fe$_2$D$_{4.2}$ compound exhibits unusual magnetic properties with different field induced magnetic transitions. The deuteride is ferrimagnetic at low temperature and the Er and Fe sublattices present magnetic transitions at different temperatures. The Er moments are ordered below T$_{Er}$=55 K, whereas the Fe moments remain ferromagnetically coupled up to T$_{M0}$ = 66 K. At T$_{M0}$ the Fe moments display a sharp ferromagnetic-antiferromagnetic transition (FM-AFM) through an itinerant electron metamagnetic (IEM) behaviour very sensitive to any volume change. Y$_{0.7}$Er$_{0.3}$Fe$_2$D$_{4.2}$ becomes paramagnetic above T$_N$=125 K. The pressure dependence of T$_{Er}$ and T$_{M0}$ have been extracted from magnetic measurements under hydrostatic pressure up to 0.49 GPa. Both temperatures decrease linearly upon applied pressure with dT$_{Er}$/dP=-126 and dTM0/dP=-140 K.GPa$^{-1}$ for a field of B=0.03 T. Both magnetic Er and ferromagnetic Fe order disappear at P=0.44(4) GPa. However, under a larger applied field B=5 T, dT$_{M0}$/dP=-156 K.GPa$^{-1}$ whereas dT$_{Er}$/dP=-134 K.GPa$^{-1}$ showing a weaker sensitivity to pressure and magnetic field. At 2 K the decrease of the saturation magnetization under pressure can be attributed to a reduction of the mean Er moment due to canting and/or crystal field effect. Above T$_{M0}$ the magnetization curves display a metamagnetic behaviour from AFM to FM state, which is also very sensitive to the applied pressure. The transition field B$_{trans}$, which increases linearly upon heating, is shifted to lower temperature upon applied pressure with dT=-17 K between 0 and 0.11 GPa. These results show a strong decoupling of the Er and Fe magnetic sublattices versus temperature, applied field and pressure.
