Abstract:
The scattering intensity of synchrotron radiation in a compact three-dimensional volume of the reciprocal space (sinθmax/λ = 0.6283 Å−1) of an SrTiO3single crystal has been measured at temperatures of 115, 130 and 293 K. The curvilinear features of the diffuse pattern were modelled according to the displacements of both cations correlated along the axis [001]cub(where the subscript cub denotes the cubic structure). The results show that Sr2+is displaced from the ideal positions along the crystallographic axis [001]cub, forming a short chain composed of about three Sr2+ions along [001]cub, while the Ti4+ions are moved in the directions [111]cub, or alternatively [101]cubor [011]cub. The Ti4+displacements are also correlated along [001]cub, forming a similarly short chain.

Abstract:
In this article, we present the command cub, which fits ordinal rating data using combination of uniform and binomial (CUB) models, a class of finite mixture distributions accounting for both feeling and uncertainty of the response process. CUB identifies the components that define the mixture in the baseline model specification. We apply maximum likelihood methods to estimate feeling and uncertainty parameters, which are possibly explained in terms of covariates. An extension to inflated CUB models is discussed. We also present a subcommand, scattercub, for visualization of results. We then illustrate the use of cub using a case study on students’ satisfaction for the orientation services provided by the University of Naples Federico II in Italy.

Abstract:
5014 Background: CS have been used to mitigate mineralocorticoid-related effects and restore sensitivity to AA (Attard et al., J Clin Oncol. 2008). Prednisone (P) was also used as an active comparator in the COU-AA-301 (de Bono et al., N Engl J Med. 2011) and COU-AA-302 (Ryan et al., N Engl J Med. 2013) AA pivotal studies. CUB has also been reported to adversely influence OS in the AFFIRM study, which may reflect an influence on disease biology or unrecognized factors that are not a part of clinically based prognostic models (Scher et al., Ann Oncol. 2012). This post hoc exploratory analysis investigated whether CUB is a prognostic factor for OS in mCRPC post-D pts treated with AA + P or P alone. Methods: COU-AA-301 is a randomized double-blind study of AA (1 g) + P (5 mg po BID) vs placebo + P in mCRPC post-D. The primary endpoint was OS. All pts had received CS with D therapy. CUB included P (n = 272), dexamethasone (n = 107), and others (n = 110). 797 pts were not on CUB. Median times were estimated by the product-limit method; Cox model was used to obtain the hazard ratio (HR) and associated confidence interval (CI). Results: Pts with CUB had worse baseline disease characteristics (including adverse ECOG PS, Gleason score, analgesic score, and LDH) (all p < 0.05). Pts receiving CUB had inferior OS; AA + P improved OS independent of CUB. (Table). CUB was an independent prognostic factor in multivariate analysis (p = 0.03; HR 1.22 [95% CI: 1.02-1.45]) that was associated with lower baseline androgen levels (p < 0.0001). In a stepwise selection model, CUB was not an independent prognostic factor. Conclusions: In this study, CUB was not a strong independent prognostic factor in mCRPC post-D pts treated with AA + P or P alone. CUB was associated with worse baseline disease characteristics and inferior OS in this study, in which all pts subsequently received CS. Clinical trial information: NCT00638690. [Table: see text]

Abstract:
Gouty arthritis is a common inflammatory disease characterized by monosodium urate (MSU) crystal-induced nucleotide-binding oligomerization domain (NOD)-like receptor (NLR) family pyrin domain containing 3 (NLRP3) inflammasome activation with upregulated caspase 1 protease and IL-1β in macrophages. Cucurbitacin B (CuB) is a tetracyclic triterpene that possesses a potential anti-inflammatory activity. However, the immunomodulatory and anti-inflammatory effects of CuB on gout have not been well characterized. Therefore, the purpose of the present study was to determine whether CuB exhibits anti-inflammatory effects on gout and to analyze the underlying molecular mechanism. We examined the effects of CuB on various stimuli-activated bone marrow-derived macrophages (BMDMs) and in a mouse model with MSU-induced acute gouty arthritis. Our results demonstrated that CuB effectively suppressed multiple stimuli-activated IL-1β secretion by interrupting NLRP3 inflammasome complex formation, inhibiting NLRP3 inflammasome activation and suppressing key enzymes of glycolysis in macrophages. Consistent with this, CuB pretreatment also ameliorated MSU-induced arthritis in vivo models of gout arthritis, manifested by reduced foot swelling and inflammatory cell infiltration. Taken together, our data provide the evidence that CuB is an NLRP3 inflammasome inhibitor with therapeutic potential for treating NLRP3 inflammasome-mediated diseases, especially gouty arthritis.

Abstract:
The budding yeast Saccharomyces cerevisiae has been used as a model organism for the basic mechanism of aging, which provides useful assay systems for measuring both replicative and chronological lifespans. In the course of our screening program for substances that extend replicative lifespan, cucurbitacin B (CuB) was found as a hit compound from a compound library, which contains cerebrosides, phenols, sesquiterpenoid, triterpenoids, and sterols isolated from natural products by our research group. Importantly, it prolonged not only the replicative lifespan but also the chronological lifespan in yeast. CuB increased ATG32 gene expression, suggesting that CuB induces autophagy. Indeed, the GFP signal generated from the cleavage of GFP-Atg8, which is a signature of autophagy, was increased upon CuB treatment. On the other hand, CuB failed to increase the chronological lifespans when either ATG2 or ATG32, essential autophagy genes, was deleted, indicating that the lifespan extension by CuB depends on autophagy induction. Furthermore, CuB significantly increased superoxide dismutase (Sod) activity and the survival rate of yeast under oxidative stress, while it decreased the amount of reactive oxygen species (ROS) and malondialdehyde (MDA) production, indicating that CuB has activity to antagonize oxidative stress. Additionally, CuB did not affect replicative lifespans of sod1, sod2, uth1, and skn7 mutants with the K6001 background, indicating that aging-related genes including SOD1, SOD2, UTH1, and SKN7 participate in the antiaging effect of CuB. These results suggest that CuB exerts antiaging activity by regulating autophagy, ROS, antioxidative ability, and aging-related genes. Finally, we discuss the possible intracellular targets of CuB based on the phenotypic comparison between the CuB and global gene deletion databases.

Abstract:
Non-small cell lung cancer (NSCLC) patients carrying an epidermal growth factor receptor (EGFR) mutation are initially sensitive to EGFR-tyrosine kinase inhibitors (TKIs) treatment, but soon develop an acquired resistance. The treatment effect of EGFR-TKIs-resistant NSCLC patients still faces challenges. Cucurbitacin B (CuB), a triterpene hydrocarbon compound isolated from plants of various families and genera, elicits anticancer effects in a variety of cancer types. However, whether CuB is a viable treatment option for gefitinib-resistant (GR) NSCLC remains unclear. Here, we investigated the anticancer effects and underlying mechanisms of CuB. We report that CuB inhibited the growth and invasion of GR NSCLC cells and induced apoptosis. The inhibitory effect of CuB occurred through its promotion of the lysosomal degradation of EGFR and the downregulation of the cancerous inhibitor of protein phosphatase 2A/protein phosphatase 2A/Akt (CIP2A/PP2A/Akt) signaling axis. CuB and cisplatin synergistically inhibited tumor growth. A xenograft tumor model indicated that CuB inhibited tumor growth in vivo. Immunohistochemistry results further demonstrated that CuB decreased EGFR and CIP2A levels in vivo. These findings suggested that CuB could suppress the growth and invasion of GR NSCLC cells by inducing the lysosomal degradation of EGFR and by downregulating the CIP2A/PP2A/Akt signaling axis. Thus, CuB may be a new drug candidate for the treatment of GR NSCLC.

Abstract:
The class of CUB models is commonly used by practitioners to model ordinal data, in this paper we propose the cubm package which provides the class of CUB models in the R system for statistical computing. The cubm package allows to specify a formula for each parameter of the model, the Maximum Likelihood (ML) estimation is performed by optimization via the functions nlminb, optim and DEoptim and the variance-covariance matrix can be obtained by numerical approximation of the Hessian matrix or by bootstrap method. The utility of the package is illustrated by an application and a simulation study.

Abstract:
The polydactylous rat strain (PD/Cub) is a highly inbred (F > 90) genetic model of metabolic syndrome. The aim of this study was to analyze the genetic architecture of the metabolic derangements found in the PD/Cub strain and to assess its dynamics in time and in response to diet and medication. We derived a PD/Cub × BN/Cub (Brown Norway) F2 intercross population of 149 male rats and performed metabolic profiling and genotyping and multiple levels of genetic linkage and statistical analyses at five different stages of ontogenesis and after high-sucrose diet feeding and dexamethasone administration challenges. The interval mapping analysis of 83 metabolic and morphometric traits revealed over 50 regions genomewide with significant or suggestive linkage to one or more of the traits in the segregating PD/Cub × BN/Cub population. The multiple interval mapping showed that, in addition to “single” quantitative train loci, there are more than 30 pairs of loci across the whole genome significantly influencing the variation of particular traits in an epistatic fashion. This study represents the first whole genome analysis of metabolic syndrome in the PD/Cub model and reveals several new loci previously not connected to the genetics of insulin resistance and dyslipidemia. In addition, it attempts to present the concept of “dynamic genetic architecture” of metabolic syndrome attributes, evidenced by shifts in the genetic determination of syndrome features during ontogenesis and during adaptation to the dietary and pharmacological influences.

Abstract:
College and university-based (CUB) summer camps are a prominent pre-collegiate experience targeting middle and high school adolescents, which research suggests may enhance college aspirations and preparedness, develop academic knowledge and skills, and influence future career choices. This study examines factors that predict the relation between affinity for college, program engagement and support, college major selection, and social–emotional outcomes stemming from youth involvement in a CUB camp based on data collected from 641 middle and high school-aged youth who completed an online questionnaire on the last day of the CUB camp. The findings validated a 4-factor model comprised of college brand awareness, college relational expectations, college academic interest–science, and college academic interest–technology. Further, the structural equation model (SEM) results suggested a relation between affinity for college, program engagement and support, and social–emotional outcomes. In addition, a CUB camp student’s lack of a college major had a significant negative direct effect on some dimensions of affinity for college including college brand awareness, college relational expectations, and college academic interest–science. CUB camp providers can use the results of this study to better articulate how their programs might impact adolescent decision making related to college, as well as inform how CUB camp providers may intentionally create affinity spaces that maximize student awareness of college brands as well as their future expectations for the college experience.

Abstract:
This thesis reports the synthesis and copper coordination chemistry of covalently-linked aryl-imidazole derivatives designed as models for the crosslinked imidazole-phenol sidechains of the His-Tyr cofactor in the CcO. Three new imidazole- (HL1 - HL3) and three new indole- (HL4 - H2L6) containing tripodal ligands were synthesised. The conjugate addition of an imidazole to activated quinone derivatives was developed as a new route to organic models for the Tyr His cofactor. Two monodentate imidazole-aryl, Im-hq(OH)2 and Im-ArOH, and an imidazole-quinone, Im bq were obtained using this route. The X-ray crystal structure of Im-hq(OH)2.EtOH was determined. The route was also used to give new chelating ligands, H2L10 and HL12, containing a cross-linked imidazole-phenol surrogate for the Tyr244-His240 cofactor. Copper complexes of Im-hq(OH)2, Im-bq, Im-ArOH, H2L10-HL12, and HL1-H2L6 were prepared, and the X-ray crystal structures of [Cu(terpy)(Im-bq)][BF4]2 and five other copper complexes were determined. The physiochemical properties of the copper complexes were characterized by FT-IR, UV-Vis-NIR, EPR and (spectro)electrochemical studies. Key results include: the oxidation of Im-ArO- anion affords the semiquinone radical, Im-sq(4OH)(1O??????), in a hydrous solvent. However, the oxidations of neutral Im-ArOH and [Cu(tpa)(Im-ArOH)]2+ produce the corresponding phenoxy radical species that rapidly and reversibly dimerise to give quinol cyclohexadienone, QCHD, dimers. Significantly [Cu(tpa)(Im-sq(4OH)(1O??????))]2+ was EPR silent, perhaps due to antiferromagnetic coupling between the Cu(II) (S=1/2) and semiquinonyl radical (S=1/2) centres. Deprotonation of the hydroquinone in [Cu(tpa)(Im-hq(OH)2]2+ produces the hydroquinone dianion which reduces the Cu(II) centre. The semiquinone radical is coordinatively labile and dissociates from the Cu(I) centre. The biological implications of these results are mentioned.

Abstract:

The Hydrological Simulation Program - FORTRAN (HSPF) in its personal computer version, release 10.10, was used to perform the hydrological simulation of a sub-watershed of the Occoquan River drainage basin. The sub-watershed selected was the Cub Run Watershed located in the northern area of the Occoquan River catchment. A model in the form of a User Control Input (UCI) file was prepared. The Cub Run Watershed was analyzed considering its geological, edaphic and weather characteristics, and segmented accordingly. The model was calibrated to adjust simulated results to observed data. Several calibration runs were executed and a final run was done considering a further segmented watershed. The simulation results were good even when not all the desired data could be found. The annual percent difference between the best calibration run and the observed results was 21.28%. The ten-month percent difference, excluding June and July, was 5.82 %. The first value is a fair result for hydrologic calibration, the second value is an excellent result for the same type of calibration. Additional segmentation did not further improve the results obtained during the best calibration run. Differences in the calibration when considering just a pervious segment or two segments (one pervious and one impervious) could be noted, indicating the importance of considering impervious surfaces for the simulation. HSPF reacted quite logically to variations in the calibration parameters and the results from those variations could be predicted beforehand. In summary, the PC version of HSPF was demonstrated to be a good management tool for the hydrological simulation of this watershed.

Abstract:
Le fond diffus infrarouge (CIB) provient de l'émission IR cumulée des galaxies sur toute l'histoire de l'Univers. Ainsi, le CIB sonde la formation et l'évolution des galaxies sur une grande gamme de décalage vers le rouge. Dans cette thèse, nous utilisons les anisotropies du CIB pour: i) Mesurer l'histoire de la formation des étoiles de l'Univers et le biais effectif des halos de matière noire hébergeant les galaxies CIB jusqu'à un décalage rouge élevé. En utilisant ces mesures, nous calculons la masse typique de ces halos de matière noire, sur une grande gamme de décalage vers le rouge. ii) En utilisant le CIB comme traceur de la structure à grande échelle, la corrélation croisée avec le CMB fournit une sonde alternative de l'énergie noire. Nous montrons que le CIB, extrait sur une grande fraction du ciel, peut fournir la meilleure mesure de l'effet ISW. En utilisant un formalisme matriciel de Fisher, nous prédisons l'amélioration des contraintes sur les paramètres cosmologiques en utilisant l'ISW mesuré avec le CIB. iii) Mesurer le spectre de puissance de l'effet Sunyaev-Zel'dovich cinétique (kSZ) caché dans les données du CMB. Nous améliorons les analyses existantes en combinant les mesures du CIB (de Planck/HFI et Herschel/SPIRE) et les observations de Planck, SPT et ACT pour étendre la gamme des échelles spatiales et des fréquences afin de faciliter la mesure du kSZ. Nous développons un nouveau modèle pour le CIB (pour pouvoir tenir compte des petites échelles spatiales), et modélisons de façon cohérente l'effet SZ thermique (tSZ) et la corrélation CIBxtSZ. Ceci est nécessaire pour séparer avec précision ces différentes composantes dans le spectre de puissance
The CIB is the cumulative infrared emission from all the galaxies throughout cosmic history. Its distinct frequency-redshift dependence allows to probe a large span of redshifts. In this thesis, we utilise the CIB anisotropies detected by the Planck satellite to:i) Measure the star formation history of the Universe and the effective bias of the dark matter halos hosting the CIB galaxies to a high redshift. Using these measurements, we calculate the typical mass of the host dark matter halos for the CIB galaxies at different times.ii) Using the CIB as a tracer of the large scale structure, the cross-correlation with the CMB provides with an alternative probe of the dark energy. We showed that the CIB, extracted on a large fraction of the sky, may provide the best Integrated Sachs Wolf measurement (in terms of S/N ratio). Using a Fisher matrix formalism, we also predict the improvement on the constraints on the cosmological parameters using the ISW measured with this technique. We cross-correlate the best available maps of the CIB and the CMB and find that the dust residuals in the CIB maps are too high to detect the ISW through this method.iii) Measure the kinetic Sunyaev-Zel'dovich (kSZ) power spectrum hidden in the CMB power spectrum. We improve upon the existing analysis by combining the CIB measurements (from Planck/HFI and Herschel/SPIRE) and multi-frequency observations by Planck, SPT and ACT to extend the range of scales and frequencies to facilitate the kSZ measurement. We develop a power spectrum analysis based on physically motivated but simplistic and consistent models of foreground components (CIB, tSZ, tSZxCIB) to accurately separate the kSZ from the CMB

The purpose of this entrepreneurial project is to implement a business focused on unifying the supply and demand of select healthy products through an online platform (marketplace), which seeks to promote and motivate our consumers to adopt a healthier lifestyle. This project was carried out in Metropolitan Lima at SES (Socioeconomic status) "A" and “B”. We adopted a main focus on consumers with digital profiles that seek for dynamism in their purchases. This business model is attractive, since we see there are consumers willing to improve their diet and adopt a healthier lifestyle, but they do not find a place that provides a unified offer of everything they are looking for. Taking advantage that there are few options in the market where the interaction between suppliers and demanders is dynamic, we created Natural Club. This entrepreneurial project allows sellers to offer their selected and high quality products, quickly and easily, just as it is for our consumers to acquire them. All this while taking care of the delivery process, with all the sanitation and hygiene measures, due to Covid-19. For the development of this project, we carry out an exhaustive analysis that covered the following: Validation of the Business Model, Internal and External Analysis and the Development of the Strategic Plan. All the analysis was done with the aim of validating the viability and sustainability of this project.

The purpose of this entrepreneurial project is to implement a business focused on unifying the supply and demand of select healthy products through an online platform (marketplace), which seeks to promote and motivate our consumers to adopt a healthier lifestyle. This project was carried out in Metropolitan Lima at SES (Socioeconomic status) "A" and “B”. We adopted a main focus on consumers with digital profiles that seek for dynamism in their purchases. This business model is attractive, since we see there are consumers willing to improve their diet and adopt a healthier lifestyle, but they do not find a place that provides a unified offer of everything they are looking for. Taking advantage that there are few options in the market where the interaction between suppliers and demanders is dynamic, we created Natural Club. This entrepreneurial project allows sellers to offer their selected and high quality products, quickly and easily, just as it is for our consumers to acquire them. All this while taking care of the delivery process, with all the sanitation and hygiene measures, due to Covid-19. For the development of this project, we carry out an exhaustive analysis that covered the following: Validation of the Business Model, Internal and External Analysis and the Development of the Strategic Plan. All the analysis was done with the aim of validating the viability and sustainability of this project.

Abstract:
El presente proyecto de investigación tiene como finalidad la implementación de un negocio enfocado en la unificación de la oferta y la demanda de productos saludables selectos por medio de una plataforma online (marketplace), que busca promover y motivar al público a que adopte estilos de vida saludables. Este trabajo de investigación fue realizado en Lima Metropolitana a los NSE “A” Y “B”; teniendo un principal enfoque en quienes tienen perfiles digitales y buscan dinamismo en sus compras. Este modelo de negocio es atractivo, ya que vemos un consumidor interesado en mejorar su alimentación y tener un estilo de vida saludable, pero que no encuentra un lugar que le brinde una oferta unificada de todo lo que busca. Aprovechando que en el mercado existen pocas opciones que vuelvan dinámica la interacción entre ofertantes y demandantes, creamos Natural Club. Es un emprendimiento que permite a los vendedores ofertar sus productos, selectos y de alta calidad, de una manera rápida y sencilla, así como para el consumidor adquirirlos de la misma manera. Encargándose, además, de todos los envíos a domicilio y asegurándose de que cumplan con los altos estándares de salubridad que requiere la coyuntura COVID-19.

Abstract:
O custo unitário básico (CUB), foi criado em função da Lei n° 4.591 (BRASIL, 1964), que encarregou a Associação Brasileira de Normas Técnicas (ABNT), através do Banco Nacional de Habitação (BNH), de definir critérios e normas para cálculo de custos unitários de construção pelos Sindicatos das Indústrias da Construção Civil (SINDUSCON) nos Estados da Federação, para uso dos incorporadores imobiliários nas tratativas iniciais quando da viabilização junto ao Sistema Financeiro de Habitações. Com a publicação da Norma Brasileira NB 140 (ASSOCIAÇÃO BRASILEIRA DE NORMAS TÉCNICAS, 1965), ficou definido a metodologia de cálculo dos CUB para projetos-padrão de prédios habitacionais. A finalidade destes CUB é auxiliar na avaliação dos custos de incorporações imobiliárias, antes do lançamento, quando os incorporadores não dispõem dos projetos completos. A metodologia de cálculo destes CUB sofreu uma única reformulação ao longo destes quase quarenta anos, quando da edição da NBR 12.721 (ASSOCIAÇÃO BRASILEIRA DE NORMAS TÉCNICAS, 1992). Em 1999, recebeu anexo complementar, que não fez qualquer atualização na metodologia de cálculo dos CUB, apenas estendeu a apuração destes custos para edifícios comerciais, galpões industriais e casas populares Este trabalho realizou a verificação e validação do modelo de cálculo dos CUB para prédios habitacionais, fazendo comparações entre os valores apurados pela técnica recomendada na Norma e os obtidos diretamente nos orçamentos discriminados que deram origem à metodologia de cálculo dos CUB, utilizando preços unitários de insumos no período de janeiro de 1993 a dezembro de 2000. Ao final concluiu-se que o modelo de cálculo dos CUB necessita de uma profunda reformulação para readquirir a propriedade fundamental de sua caracterização que é a de substituir o cálculo dos custos com o uso do orçamento discriminado dos projetos-padrão.

Abstract:
In this dissertation, the socio-ecological transformations that occurred during Cuba’s Revolución Agrícola are explored, against the backdrop of the historical subalternisation of the country as a consequence of Spanish and American imperialism, and in relation to the continuing subalternisation of the country and its people through the neoliberal mass media. To contextualize such exploration, the origins of large-scale privatization of common land, and the subsequent process of urbanization in the West, are investigated, before Cuba’s similar developmental path – as a result of Spanish colonialism, U.S. imperialism, and communist influence – is detailed. Thereafter, the way in which Cuba established an alternative food paradigm, characterised by local, communal, and urban production during the country’s ‘Special Period’ in the 1990s, is discussed, with a view to illustrating how this eco-socialist model of food production, in both rural and urban areas, led to new relations between people and nature. This Cuban model is then posited as a socio-ecologically sustainable model of food production, deserving of the attention of communities around the world, who seek to gain a degree of autonomy from neoliberal agribusiness. Conversely, the efforts of mainstream neoliberal mass media to silence the immensely positive characteristics of the revolution are also investigated, and framed in terms of the historical subjugation of Cuban voices in the American mass media, and the contemporary marginalisation of the country and its people in the neoliberal mass media. Finally, the dissertation concludes by examining the alternative media response, on the part of several prominent Cubans and those sympathetic to their cause, to bring attention to the value of the socio-ecological transformations that have occurred on the island, against the backdrop of various theorisations of the importance of alternative media platforms as a radical counterforce to neoliberal mass media hegemony.

Abstract:

Vision systems, such as "seeing" robots, should be able tooperate robustly in generic environments. In this thesis, weinvestigate certain aspects of how these demands of robusmessof a systems approach to vision could be met.

Firstly, we suggest that robustness can be improved byfusing the variety of infor mation offered by the environment,and, therefore, we investigate the effectiveness of using thecoincidence of multiple cues. Secondly, we are concerned aboutthe use of coarse algorithms. Even though the environmentprovides much information, it is neither necessary nor possibleto extract all information available. Therefore, we will showthat coarse algorithms will suffice for certain problems. Toinvestigate the effectiveness of using the coincidence ofmultiple cues, we perform a series of experiments on detectingplanar surfaces in binocular images. These experiments arebased on two schemes of a somewhat different character.

The first one is ahyporhesls-and-testscheme that incorporates the cues ina certaln order and hence, by design, imposes a ranking ofthem. The general idea is to use arbitrary cues exploitinglocal image data to get an idea about whether the model (aplanar surface) is seen in the image and at which location itis found. If one or more cues strongly indicate a certaininstance of a model, then this observation serves as ahypothesis to be tested by other cues to support or reject thishypothesis. In comparison to the cues used for hypothesisgeneration, those used for hypothesis testing should be morereliable and can also have a higher computational complexitysince they are only employed when needed.The general idea of the second scheme is to first use asimple, and quick cue exploiting local image data toget anidea of where in the image the model (a planar surface) couldbe found. After this initial localization step, all cues thatcan be computed are gathered and allowed tovorefor the occurrence of the model in the hypothesizedregion. The initialization of this approach is a hypothesisforming step, similar to that of the hypothesis-and-testapproach This step though, is much weaker because it onlyindicates a region in the images where to look. The approachallows direct fusion of incommensurable cues, such as intensityand surface orientation. Generally, it can be regarded as aless restrictive approach than the hypothesis-and-test approach. We propose that coarse algorithms may be motivated from arobustness and flexibtl hy point of view. Our experimentsdemonstrate that there is support for this claim, at least, forsome tasks of relevante, such as those of finding planarsurfaces, or similar simple models.

Abstract:
Machine learning classifiers’ capability is largely dependent on the scale of available training data and limited by the model overfitting in data-scarce learning tasks. To address this problem, this work proposes a novel Meta Functional Learning (MFL) by meta-learning a generalisable functional model from data-rich tasks whilst simultaneously regularising knowledge transfer to data-scarce tasks. The MFL computes meta-knowledge on functional regularisation generalisable to different learning tasks by which functional training on limited labelled data promotes more discriminative functions to be learned. Moreover, we adopt an Iterative Update strategy on MFL (MFL-IU). This improves knowledge transfer regularisation from MFL by progressively learning the functional regularisation in knowledge transfer. Experiments on three Few-Shot Learning (FSL) benchmarks (miniImageNet, CIFAR-FS and CUB) show that meta functional learning for regularisation knowledge transfer can benefit improving FSL classifiers.

Abstract:
The generation task from text to image generates cross modal data with consistent content by mining the semantic consistency contained in two different modal information of text and image. Due to the differences between the two modes, the task of text to image generation faces many difficulties and challenges. In this paper, we propose to boost the text-to-image synthesis through an adaptive learning and generating generative adversarial networks (ALG-GANs). First, we propose an adaptive forgetting mechanism in the generator to reduce the error accumulation and learn knowledge flexibly in the cascade structure. Besides, to evade the mode collapse caused by a strong biased surveillance, we propose a multi-task discriminator using weaksupervision information to guide the generator more comprehensively and maintain the semantic consistency in the cascade generation process. To avoid the refine difficulty aroused by the bad initialization, we judge the quality of initialization before further processing. The generator will re-sample the noise and re-initialize the bad initializations to obtain good ones. All the above contributions have been integrated in a unified framework, which is an adaptive forgetting, drafting and comprehensive guiding based text-to-image synthesis method with hierarchical generative adversarial networks. The model is evaluated on the Caltech-UCSD Birds 200 (CUB) dataset and the Oxford 102 Category Flowers (Oxford) dataset with standard metrics. The results on Inception Score (IS) and Fréchet Inception Distance (FID) show that our model outperforms the previous methods.

Abstract:
Generative methods have been successfully applied in zero-shot learning (ZSL) by learning an implicit mapping to alleviate the visual-semantic domain gaps and synthesizing unseen samples to handle the data imbalance between seen and unseen classes. However, existing generative methods simply use visual features extracted by the pre-trained CNN backbone. These visual features lack attribute-level semantic information. Consequently, seen classes are indistinguishable, and the knowledge transfer from seen to unseen classes is limited. To tackle this issue, we propose a novel Semantic Compression Embedding Guided Generation (SC-EGG) model, which cascades a semantic compression embedding network (SCEN) and an embedding guided generative network (EGGN). The SCEN extracts a group of attribute-level local features for each sample and further compresses them into the new low-dimension visual feature. Thus, a dense-semantic visual space is obtained. The EGGN learns a mapping from the class-level semantic space to the dense-semantic visual space, thus improving the discriminability of the synthesized dense-semantic unseen visual features. Extensive experiments on three benchmark datasets, i.e., CUB, SUN and AWA2, demonstrate the significant performance gains of SC-EGG over current state-of-the-art methods and its baselines.

Abstract:
This paper describes a model for studying collaborative knowledge building (CKB) as a group activity. We integrate the model described by Stahl (2000a) with an analysis based on the principles of cultural historical activity theory (CHAT), using the analysis of a self reflective case study to guide the description. The concept of the CKB activity system is developed, and the role of contradictions in CHAT is described. The case is then analyzed to show how the model explains collaboration in practice. The final model includes two additional cycles representing the role of reflective practice in CKB. The new model of CKB processes combined with the concept of the activity as the unit of analysis and the tools of CHAT provides an efficacious way of investigating collaborative knowledge building.

Abstract:
In recent years, innovative mobility and shifts in travel and consumption behavior are changing how people access and use the curb. Shared mobility—the shared use of a vehicle, bicycle, scooter, or other mode—coupled with outdoor dining, curbside pick-up, and robotic delivery are creating new needs related to the planning, management, and enforcement of curb access. This study examines curb planning and management from several angles, such as safety, social equity, and multimodal connections. This research employs a multi-method approach to identify the changing needs for curb space management and how to meet these needs through new planning and implementation policies and strategies. As part of this study, the authors conducted 23 interviews. Respondents were chosen to represent public, private, and non-profit sector perspectives. Additionally, the authors employed a survey of 1,033 curb users and 241 taxi, transportation network company (TNC), and public transportation drivers. The study finds that changes in mode choice and curbside use can result in a variety of impacts on access, social equity, congestion, device management, pick-up and drop-off, and goods delivery, to name a few. The curb also has the potential to be disrupted by emerging modes, such as robotic delivery vehicles (also known as personal delivery devices) and automated vehicles. As these emerging developments continue to impact the curb, it is becoming increasingly important for policymakers to have an appropriate framework for planning and managing curb space in urban areas.
