description: Objective: State-of-the-art collision avoidance and collision mitigation systems predict the behavior of pedestrians based on trivial models that assume a constant acceleration or velocity. New sources of sensor information—for example, smart devices such as smartphones, tablets, smartwatches, etc.—can support enhanced pedestrian behavior models. The objective of this article is the development and implementation of a V2Xpedestrian collision avoidance system that uses new information sources. Methods: A literature review of existing state-of-the-art pedestrian collision avoidance systems, pedestrian behavior models in advanced driver assistance systems (ADAS), and traffic simulations is conducted together with an analysis of existing studies on typical pedestrian patterns in traffic. Based on this analysis, possible parameters for predicting pedestrian behavior were investigated. The results led to new requirements from which a concept was developed and implemented. Results: The analysis of typical pedestrian behavior patterns in traffic situations showed the complexity of predicting pedestrian behavior. Requirements for an improved behavior prediction were derived. A concept for a V2X collision avoidance system, based on a cost function that predicts pedestrian near future presence, and its implementation is presented. The concept presented considers several challenges such as information privacy, inaccuracies of the localization, and inaccuracies of the prediction. Conclusion: A concept for an enhanced V2X pedestrian collision avoidance system was developed and introduced. The concept uses new information sources such as smart devices to improve the prediction of the pedestrian's presence in the near future and considers challenges that come along with the usage of these information sources.

description: In this Essay I hope to examine the complex relationship between Karol Szymanowski (b.3 October 1882, d. 28 March 1937) and his contemporary Henryk Górecki (b. December 6 1933, d. November 12, 2010) born 51 years later. I also hope to explore the link that Bolesław Szabelski provided as Szymanowski's student and later as Górecki's teacher. I also hope to complete an analysis of Górecki's Symphony no.3 Op. 36 (1976) and compare it to aspects of Szymanowski's Stabat Mater (1926).

description: In this study, nanosilica/crosslinked Polyacrylamide (PAM) microsphere with a core–shell structure is designed to make a functional material, where nanosilica provides the rigidity, stiffness and strength, the crosslinked PAM provides the flexibility and elasticity. The structure mentioned above make the resulting microspheres to be able to enter, expand, shut off and be removed from deep layers of oilfields. A methodology to create the nanosilica/crosslinked PAM microsphere with a core–shell structure has been developed, and molecular dynamic (MD) simulations are applied to successfully study the interaction between the microsphere and water in aqueous solution of nanosilica/crosslinked PAM microsphere and its swelling behavior. Results including the interaction energies (Einter) between nanosilica and crosslinked PAM, Einter between the microsphere and water molecules, radius of gyrations (Rg) of the microsphere, the radial distribution functions of microsphere-water pairs, the mean square displacements and the diffusion coefficients (D) of water are calculated and analyzed in detail. The experimental results of particle diameter tested from dynamic light scattering have been used to verify the simulation results of swelling behavior. The interaction between nanosilica/crosslinked PAM microsphere and water in aqueous solution and its swelling behavior are studied.

description: Objective: To study the association between cardiac function measured by myocardial performance index (MPI), blood pressures and angiogenic factors measured at the time of echocardiography in patients with and without hypertensive disorders of pregnancy (HDP). Methods: We prospectively studied 189 pregnant women and evaluated whether changes in cardiac function observed on echocardiography were correlated with higher blood pressures and whether higher blood pressures were associated with antiangiogenic proteins (soluble fms-like tyrosine kinase, sFlt1; soluble endoglin, sEng). Comprehensive echocardiograms, including measurement of MPI, were performed on all patients. sFlt1 and sEng levels were measured using enzyme-linked immunosorbent assay. Results: Overall, 189 patients were divided into tertiles based on mean arterial pressure (MAP). The MPI was worst in tertile 3 (0.50 ± 0.15) compared to tertile 1 (0.42 ± 0.10), p = 0.0004. sFlt1 (pg/ml) and sEng (ng/ml) were highest in tertile 3 compared to tertile 1: 15055.37 vs. 1623.01 and 33.06 vs. 8.15, respectively, with p-value <0.001. In crude multivariate regression analysis, MAP was positively correlated with MPI (r = 0.32, p < 0.001), GLS (r = 0.54, p < 0.001), sFlt1 (r = 0.60, p < 0.001) and sEng (r = 0.61, p < 0.001). After adjustment for confounders, these relationships persisted between MAP and MPI (r = 0.31, p = 0.0003), GLS (r = 0.46, p < 0.001), sFlt1 (r = 0.56, p < 0.001) and sEng (r = 0.58, p < 0.001). Conclusion: Mean arterial pressure correlates with worsening cardiac function as measured by MPI and serum levels of angiogenic factors. Further studies are needed to evaluate whether a reduction in blood pressure will reverse changes in MPI or reduce levels of angiogenic proteins seen among women with HDP.

description: Tesis para la obtención del título de Doctora en Historia y Teoría de las Artes presentada en la Facultad de Filosofía y Letras de la Universidad de Buenos Aires en octubre de 2019 y defendida en febrero de 2020. La tesis aborda, como tema general, el renovado interés por lo real verificado en distintas expresiones de la escena teatral argentina e internacional en el siglo XXI. En ese marco, pone el foco específicamente en el trabajo reciente Vivi Tellas, una figura muy destacada de la escena local desde los años ochenta, quien es frecuentemente mencionada por la crítica especializada, pero cuya trayectoria no había sido aún estudiada de modo integral. Esta investigación aborda, en particular, la etapa más reciente de su actividad como directora teatral y curadora, buscando, en primer lugar, sistematizar una periodización y conceptualización del teatro biográfico y documental que ha desarrollado e impulsado desde las distintas manifestaciones de su Proyecto Biodrama. Estas manifestaciones son, principalmente, el Ciclo Biodrama en el Teatro Sarmiento (del que fuecuradora entre 2002 y 2009), el Proyecto Archivos (serie de espectáculos con intérpretes no profesionales que dirigió entre 2003 y 2008) y la sucesión de puestas en escena que dirigió posteriormente a las que presentó como biodramas. A su vez, se intenta tanto describir como comprender algunas de las claves de la enorme productividad que el proyecto ha tenido y que sin dudas ha marcado la escena teatral contemporánea de Buenos Aires, teniendo también una gran repercusión más allá de ella.

 En síntesis, esta investigación se propone documentar, describir y analizar las experiencias teatrales vinculadas al programa artístico de la directora argentina Vivi Tellas de las últimas décadas,considerándolas al mismo tiempo representativas y promotoras de la afirmación a nivel local de una renovada búsqueda de lo real en la escena contemporánea. La intención es favorecer un conocimiento más amplio y sistemático de estas propuestas, articulando suestudio con un andamiaje conceptual que permita abordar las prácticas biográficas y documentales en sus implicancias estéticas, éticas y políticas. Finalmente, al seguir el recorrido artístico de Tellas,se busca también dar cuenta de las distintas vías en las que un/aartista puede impactar en el campo al que pertenece, así como también identificar las imbricaciones entre su trabajo a nivel local y las tendencias desarrolladas tanto en la práctica como en la teoría del arte a nivel internacional.

description: We discuss the challenges of motivating, constructing, and quantizing a canonically normalized inflationary perturbation in spatially curved universes. We show that this has historically proved challenging due to the interaction of nonadiabaticity with spatial curvature. We construct a novel curvature perturbation that is canonically normalized in the sense of its equation of motion and is unique up to a single scalar parameter. With this construction it becomes possible to set initial conditions invariant under canonical transformations, overcoming known ambiguities in the literature. This corrected quantization has potentially observational consequences via modifications to the primordial power spectrum at large angular scales, as well as theoretical implications for quantization procedures in curved cosmologies filled with a scalar field.

description: Gomphotherium is a stem taxon of Elephantida that was widespread in Africa, Eurasia, and North America during the Miocene. However, the evolution of this genus is greatly debated because of morphological variation among the species of Gomphotherium. In the present work, we describe a cranium and accompanying material of Gomphotherium from the late middle Miocene Hujialiang Formation of Linxia Basin, China. The new material shows dental similarities to G. subtapiroideum from the middle Miocene of Europe; however, it displays some cranial, mandibular, and dental feature combinations that are distinct from the known species of Gomphotherium. Therefore, a new species, G. tassyi, is established. We further study the phylogeny of Gomphotherium by cladistic analysis and recognize four groups. The most basal ‘G. annectens group’ is a paraphyletic group that includes G. annectens, G. cooperi, G. sylvaticum, and G. hannibali. The African taxa, G. libycum and G. pygmaeus, constitute a monophyletic group that has not been named. The ‘G. angustidens group’ is a monophyletic group that includes G. inopinatum, G. mongoliense, G. connexum, and G. angustidens. In addition, the ‘derived Gomphotherium group,’ which includes G. subtapiroideum, G. tassyi, G. wimani, G. browni, G. productum, and G. steinheimense, was widely distributed in Eurasia and North America during the middle and late Miocene. http://zoobank.org/urn:lsid:zoobank.org:act:28B89A74-7FF6-41DB-BA3C-C4CDD200A30F SUPPLEMENTAL DATA—Supplemental materials are available for this article for free at www.tandfonline.com/UJVP Citation for this article: Wang, S.-Q., Y.

description: Electronic spectra of hexaamminecobalt(III) complex cation in aqueous solution were analyzed to obtain spectral components. Subsequently, based on the spectral components, the coordination geometry around the cobalt(III) ion was investigated, using the reverse angular overlap model method. The result indicates that the geometry is a trigonally compressed octahedron with the polar angle of 57.9 ± 1.0° under D3d symmetry, where the polar angle is the angle between the trigonal axis and the Co–N bond. From this angle, the top and side N–Co–N bond angles are calculated as 94.4° and 85.6°, respectively. The density functional theory computation supported this trigonally compressed structure in aqueous solution.

description: In this article, we establish the mathematical foundations for modeling the randomness of shapes and conducting statistical inference on shapes using the smooth Euler characteristic transform. Based on these foundations, we propose two chi-squared statistic-based algorithms for testing hypotheses on random shapes. Simulation studies are presented to validate our mathematical derivations and to compare our algorithms with state-of-the-art methods to demonstrate the utility of our proposed framework. As real applications, we analyze a data set of mandibular molars from four genera of primates and show that our algorithms have the power to detect significant shape differences that recapitulate known morphological variation across suborders. Altogether, our discussions bridge the following fields: algebraic and computational topology, probability theory and stochastic processes, Sobolev spaces and functional analysis, analysis of variance for functional data, and geometric morphometrics.

description: Particle emissions from multiple fused deposition modeling consumer 3D printers were systematically quantified utilizing an established emission testing protocol (Blue Angel) to allow quantitative exposure assessments for printers operating in different environments. The data are consistent with particle generation from volatilization of the polymer filament as it is heated by the extruder. Typically, as printing begins, a burst of new particle formation leads to the smallest sizes and maximum number concentrations produced throughout the print job. For acrylonitrile butadiene styrene (ABS) filaments, instantaneous concentrations were up to 106 #/cm3 with mean particle sizes of 20 to 40 nm when measured in a well mixed 1 m3 chamber with 1 air change per hour. Particles are continuously formed during printing and the size distribution evolves consistent with vapor condensation and particle coagulation. Particles emitted per mass of filament consumed (particle yield) varied widely due to factors including printer brand, and type and brand of filament. Higher extruder temperatures result in larger emissions. For filament materials tested, average particle number yields ranged from 7.3 × 108 to 5.2 × 1010 g−1 (approximately 0.65 to 24 ppm), with trace additives apparently driving the large variations. Nanoparticles (diameters less than 100 nm) dominate number distributions, whereas diameters in the range of 200 to 500 nm contribute most to estimated mass. Because 3D printers are often used in public spaces and personal residences, the general public and particularly susceptible populations, such as children, can be exposed to high concentrations of non-engineered nanoparticles of potential toxicity.

description: We develop a general framework for distribution-free predictive inference in regression, using conformal inference. The proposed methodology allows for the construction of a prediction band for the response variable using any estimator of the regression function. The resulting prediction band preserves the consistency properties of the original estimator under standard assumptions, while guaranteeing finite-sample marginal coverage even when these assumptions do not hold. We analyze and compare, both empirically and theoretically, the two major variants of our conformal framework: full conformal inference and split conformal inference, along with a related jackknife method. These methods offer different tradeoffs between statistical accuracy (length of resulting prediction intervals) and computational efficiency. As extensions, we develop a method for constructing valid in-sample prediction intervals called rank-one-out conformal inference, which has essentially the same computational efficiency as split conformal inference. We also describe an extension of our procedures for producing prediction bands with locally varying length, in order to adapt to heteroskedascity in the data. Finally, we propose a model-free notion of variable importance, called leave-one-covariate-out or LOCO inference. Accompanying this paper is an R package conformalInference that implements all of the proposals we have introduced. In the spirit of reproducibility, all of our empirical results can also be easily (re)generated using this package.

description: This study sought to develop and test a model for the formalisation of human resource practices among family-owned accommodation Small and Medium-sized Enterprises (SMEs) in South Africa. This is against the background of extant literature indicating that (1) the family-owned accommodation SMEs have become work intensive and their success depends heavily on the proper management of the social and technical skills of employees, (2) human resource practices in SMEs in general are reactive and informal unlike those in larger companies, and (3) the calls by policy makers to formalise SMEs to widen the government tax bracket, create employment and redress the legacy of apartheid inequalities. Such calls have not been adequately addressed by previous studies that focused on drivers of formalising HR practices among SMEs using single and limited factors in individual studies. As a result, this study takes a holistic approach through a sustained exploration of how personal and environmental factors interact with selected factors that are critical in decision making as espoused by the Unified Theory of Acceptance and Use of Technology (UTAUT) model to influence the decision to formalise HR practices by owner-managers of family-owned accommodation SMEs in the Free State Province of South Africa.
An Ethnographic Study on Ethnic and Malawian Entrepreneurs Lived Experiences.

Subjects: Uncategorized

description: This thesis examines Ethnic and Malawian entrepreneur’s lived experiences in Mchesi, Malawi using an Ethnographic approach. Underlying this primary purpose, is my observations that general and Ethnic Entrepreneurship theories have emerged from developed economies; as such, a plethora of available general and Ethnic Entrepreneurship literature presents a developed world context understanding of Ethnic Entrepreneurship. Therefore, in using Ethnography, this study draws more widely on explanations of immigrants’ experiences in the micro practices of everyday practises to challenge the leading Ethnic entrepreneurship theoretical understandings and produce more relevant insights, reflective of the heterogeneity of immigrant populations in Malawi, Mchesi. The study involved approximately three months of fieldwork at Mchesi market in the city of Lilongwe in Malawi with twenty-six participants contributing to this study.The findings and discussions revealed three main themes: Business meanings, capital perspectives and risk and opportunity perspectives. These three main themes reveal a contextualised understanding of Entrepreneurship constructs such as entrepreneurial capital, risk, opportunity and business meanings. Thus, in revealing Mchesi Ethnic and Malawian entrepreneurial perspectives, the findings offer insights into the integral role of contextual factors including adaptation and social-economic aspects as nurtures of entrepreneurial perspectives. However, by accentuating the contextual embedded entrepreneurial perspectives, the findings also challenge other general and Ethnic Entrepreneurship perspectives that offers a one size fits all understanding of Entrepreneurship. Therefore, this thesis contribute knowledge on lived experiences and entrepreneurial perspectives of Mchesi Ethnic and Malawian Entrepreneurs especially considering that In Malawi, there are fewer Ethnographic studies on Malawian and Ethnic Entrepreneurs lived experiences.

description: Small molecules drugs are a long time favorites of those involved in frug discovery and development because these medicines tend to be easier to use and cost less to make. Additionally, they can be developed to tackle a wide range of diseases and molecular targets. However, not every target protein in our cells contains a small molecule binding pocket, which means that small molecule drugs have limitations in terms of what indications they can be developed for. Moreover, they often hit more than a single target, which means that they may be toxic or lead to undesirable side-effects. Targeted protein degradation is an emerging interest in drug discovery and development. Small molecule degraders induce degradation of their target, instead of inhibition and exhibit more durable effects at lower concentrations. Additionally, they don't require tight binding and can therefore be made even for targets that lack well-defined binding pockets. All this makes them of interest, and here we use a Strengths-Weaknesses-Opportunities-Threats (SWOT) framework to critically assess the current status of this rapidly evolving field.

description: The emergence of collective order in matter is among the most fundamental and intriguing phenomena in physics. In recent years, the ultrafast dynamical control and creation of novel ordered states of matter not accessible in thermodynamic equilibrium is receiving much attention. Among those, the theoretical concept of dynamical multiferroicity has been introduced to describe the emergence of magnetization by means of a time-dependent electric polarization in non-ferromagnetic materials. In simple terms, a large amplitude coherent rotating motion of the ions in a crystal induces a magnetic moment along the axis of rotation. However, the experimental verification of this effect is still lacking. Here, we provide evidence of room temperature magnetization in the archetypal paraelectric perovskite SrTiO$_3$ due to this mechanism. To achieve it, we resonantly drive the infrared-active soft phonon mode with intense circularly polarized terahertz electric field, and detect a large magneto-optical Kerr effect. A simple model, which includes two coupled nonlinear oscillators whose forces and couplings are derived with ab-initio calculations using self-consistent phonon theory at a finite temperature, reproduces qualitatively our experimental observations on the temporal and frequency domains. A quantitatively correct magnitude of the effect is obtained when one also considers the phonon analogue of the reciprocal of the Einsten - de Haas effect, also called the Barnett effect, where the total angular momentum from the phonon order is transferred to the electronic one. Our findings show a new path for designing ultrafast magnetic switches by means of coherent control of lattice vibrations with light.

description: We show that in presence of a local and uncorrelated dephasing noise, quantum advantage can be obtained in the Fisher information-based lower bound of the minimum uncertainty in estimating parameters of the system Hamiltonian. The quantum advantage refers here to the benefit of initiating with a maximally entangled state instead of a product one. This quantum advantage was known to vanish in the same noisy scenario for a frequency estimation protocol. Restoration of the better precision in frequency estimation with maximally entangled probes can be obtained by incorporating an interaction between the system particles. The interaction examined here is Ising in nature, and is considered with or without a transverse magnetic field. There are instances, e.g. where frequency estimation in presence of a transverse field is considered and quantum advantage is not restored. A quantum advantage can also be obtained while estimating the strength of the introduced magnetic field along the transverse direction, whereas for the instances considered, using uncorrelated probes is better in measuring the coupling parameter of the Ising interaction. We also investigate the dependence of measurement precision on the entanglement content, which is not necessarily maximal, of the initial state. The precision in estimation of coupling constant decreases monotonically with the increase of entanglement content of the initial state, while the same for frequency estimation is independent of the entanglement content of the inputs.

description: We study quantum interior point methods (QIPMs) for second-order cone programming (SOCP), guided by the example use case of portfolio optimization (PO). We provide a complete quantum circuit-level description of the algorithm from problem input to problem output, making several improvements to the implementation of the QIPM. We report the number of logical qubits and the quantity/depth of non-Clifford T-gates needed to run the algorithm, including constant factors. The resource counts we find depend on instance-specific parameters, such as the condition number of certain linear systems within the problem. To determine the size of these parameters, we perform numerical simulations of small PO instances, which lead to concrete resource estimates for the PO use case. Our numerical results do not probe large enough instance sizes to make conclusive statements about the asymptotic scaling of the algorithm. However, already at small instance sizes, our analysis suggests that, due primarily to large constant pre-factors, poorly conditioned linear systems, and a fundamental reliance on costly quantum state tomography, fundamental improvements to the QIPM are required for it to lead to practical quantum advantage.

description: Image and video synthesis has become a blooming topic in computer vision and machine learning communities along with the developments of deep generative models, due to its great academic and application value. Many researchers have been devoted to synthesizing high-fidelity human images as one of the most commonly seen object categories in daily lives, where a large number of studies are performed based on various models, task settings and applications. Thus, it is necessary to give a comprehensive overview on these variant methods on human image generation. In this paper, we divide human image generation techniques into three paradigms, i.e., data-driven methods, knowledge-guided methods and hybrid methods. For each paradigm, the most representative models and the corresponding variants are presented, where the advantages and characteristics of different methods are summarized in terms of model architectures. Besides, the main public human image datasets and evaluation metrics in the literature are summarized. Furthermore, due to the wide application potentials, the typical downstream usages of synthesized human images are covered. Finally, the challenges and potential opportunities of human image generation are discussed to shed light on future research.

description: Il volume offre una raccolta di contributi nei quali differenti discipline - nello specifico antropologia, psicoanalisi, filosofia, diritto, storia delle dottrine politiche e storiografia - riflettono sulle problematiche epistemiche - in termini di orizzonte di senso, contenutistici e metodologici - che l'utilizzo del concetto di riconoscimento impone loro. Obiettivo è quello di mettere in evidenza come l'alterità non si riduca ad essere mero oggetto del riconoscimento, ma imponga alle discipline un continuo riposizionamento rispetto al proprio statuto scientifico.

description: The widely performance of surfactants is closely related to their interfacial activity, which is essentially determined by the molecular array behaviours at the interface, of which the studies are significance for clearly understanding their structure-performance relationships. In this paper, the detailed molecular array behaviours of green surfactant alkyl polyglycoside (APG) and the mixed systems with other types of surfactants on oil/water interface have been studied using molecular dynamics simulations, and the key theoretical principle was confirmed by quantum chemistry calculations. It was found that the hydrophilic maltose ring head groups of decyl polyglycoside (C10-APG) are prone to lie flatly at the oil–water interface, the steric hindrance results in the low interfacial density, which critically determines the limit of the interfacial activity. The interfacial adsorption behaviours of the binary mixtures of C10-APG and SDS or DATB and the ternary mixtures of C10-APG, SDS and DATB were studied in detail, how the efficient synergism effect could be achieved for the mixture to get super high interfacial activity was discussed. This study provides a strategy to reveal how the molecular interfacial behaviours determine the key interfacial characteristics of the novel surfactants, which might provide help to promote their applications.
