description: Noncommutative geometry provides both a unified description of the Standard Model of particle physics together with Einstein-Hilbert action (in euclidean signature) and some tools to go beyond the Standard Model. In this paper, we extend to the full noncommutative geometry of the Standard Model the twist (in the sense of Connes-Moscovici) initially worked out for the electroweak sector and the free Dirac operator only. Namely, we apply the twist also to the strong interaction sector and the finite part of the Dirac operator. To do so, we are forced to take into account a violation of the twisted first-order condition. As a result, we still obtain the extra scalar field required to stabilise the electroweak vacuum and fit the Higgs mass, but it now has two chiral components. We also get the additive field of 1-forms already pointed out in the electroweak model, but with a richer structure. Finally, we obtain a pair of Higgs doublets, which are expected to combine into a single Higgs doublet in the action formula, as will be investigated in the second part of this work.

This cell culture system is a modification of the original Rotating Wall Vessel developed by NASA to simulate microgravity conditions and it is commercially available through Synthecon Cellon S.r.l. (Strassen Luxemburg). RCCS consists of a relatively large container (vessel) with gas exchange membrane. The culture chamber with diffusion gas exchange is completely filled with culture medium. The fluid mass rotation is accomplished by the vessel rotating horizontally around its axis, randomizing the gravitational forces acting on the cell surface. Indeed, as the vessel rotates, cells are subjected by a constantly changing angular gravity vector. b Expression of stem cell markers assessed in RPCs cultured for 72 h at 1 × g (green) and in modeled μg (pink) conditions by RT-PCR.

Conformal Moduli and b-c Pictures for NSR Strings

Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We explore the geometry of the superconformal moduli of the NSR superstring theory in order to construct the consistent sigma-model for the NSR strings, free of picture-changing ambiguities. The sigma-model generating functional is constructed by the integration over the bosonic and anticommuting moduli, corresponding to insertions of the vertex operators in scattering amplitudes. In particular, the integration over the bosonic moduli results in the appearance of picture-changing operators for the b-c system. Important example of the b-c pictures involves the unintegrated and integrated forms of the vertex operators. We derive the BRST-invariant expressions for the b-c picture-changing operators for open and closed strings and study some of their properties. We also show that the superconformal moduli spaces of the NSR superstring theory contain the global singularities, leading to the appearance of non-perturbative solitonic D-brane creation operators.

description: This thesis support document addresses the iterative installation series Sonic Portals that uses time-based media to explore intergenerational knowledge transmission.
Sonic Portals: QRV (2024) is a temporary structure that uses carefully considered materials – felted wool, wood, structural lashing techniques and textile layering, it is framed by two larger sculptural entities constructed of felled branches and beeswax dipped cedar boughs. Within the structure is a multichannel sound installation that gathers and synthesizes recorded media from haunted and energetically charged environments. Through processes of editing, distortion, looping, and temporal manipulation the installation invites the listener to engage with the unseen and the Beyond. Informed by Indigenous knowledge and lived experience, Sonic Portals investigates interdimensional memory, material practice as haunting, and the non-linear potentials of time-based media. It discusses an artistic methodology that shifts language around media production towards acts of gathering, acknowledgement, and spiritual reciprocity. This thesis project builds places for interconnection and haunting as decolonial practice within colonial institutions.

description: General N=(1,1) dilaton supergravity in two dimensions allows a background independent exact quantization of the geometric part, if these theories are formulated as specific graded Poisson-sigma models. The strategy developed for the bosonic case can be carried over, although considerable computational complications arise when the Hamiltonian constraints are evaluated in the presence of matter. Nevertheless, the constraint structure is the same as in the bosonic theory. In the matterless case gauge independent nonlocal correlators are calculated non-perturbatively. They respect local quantum triviality and allow a topological interpretation. In the presence of matter the ensuing nonlocal effective theory is expanded in matter loops. The lowest order tree vertices are derived and discussed, entailing the phenomenon of virtual black holes which essentially determine the corresponding S-matrix. Not all vertices are conformally invariant, but the S-matrix is invariant, as expected. Finally, the proper measure for the 1-loop corrections is addressed. It is argued how to exploit the results from fixed background quantization for our purposes.

Publisher: name: Peace Research Institute Oslo
Year: 2024

description: Remittances, strong transnational ties and return migration can lead to higher wealth and lower poverty levels in countries of origin. However, they need to be coupled with other factors to see such positive economic developments.

Key Takeaways

Remittances are an important path to higher wealth in a country of origin, but there must be low levels of inequality to see these positive impacts.

Regular contact is needed between migrants and their household members at home to see positive economic outcomes for those staying behind.

Return migration, when voluntary, can result in high wealth and low poverty levels in a country of origin.

description: The moving average (MA)-type scheme, also known as the smoothing method, has been well established within the multivariate statistical process monitoring (MSPM) framework since the 1990s. However, its theoretical basis is still limited to smoothing independent data, and the optimality of its equally or exponentially weighted scheme remains unproven. This paper aims to weaken the independence assumption in the existing MA method, and then extend it to a broader area of dealing with autocorrelated weakly stationary processes. With the discovery of the non-optimality of the equally and exponentially weighted schemes used for fault detection when data have autocorrelation, the essence that they do not effectively utilize the correlation information of samples is revealed, giving birth to an optimally weighted moving average (OWMA) theory. The OWMA method is combined with the Hotelling's $T^2$ statistic to form an OWMA $T^2$ control chart (OWMA-TCC), in order to detect a more challenging type of fault, i.e., intermittent fault (IF). Different from the MA scheme that puts an equal weight on samples within a time window, OWMA-TCC uses correlation (autocorrelation and cross-correlation) information to find an optimal weight vector (OWV) for the purpose of IF detection (IFD). In order to achieve a best IFD performance, the concept of IF detectability is defined and corresponding detectability conditions are provided, which further serve as selection criteria of the OWV. Then, the OWV is given in the form of a solution to nonlinear equations, whose existence is proven with the aid of the Brouwer fixed-point theory. Moreover, symmetrical structure of the OWV is revealed, and the optimality of the MA scheme for any IF directions when data exhibit no autocorrelation is proven.

We construct an infinite family of homologous non-isotopic symplectic tori representing a primitive homology class in E(1)_K when K is any nontrivial fibred knot in S^3. We also show how these tori can be non-isotopically embedded as homologous symplectic submanifolds in other symplectic 4-manifolds.

description: Development of formal proofs of correctness of programs can increase actual and perceived reliability and facilitate better understanding of program specifications and their underlying assumptions. Tools supporting such development have been available for over 40 years, but have only recently seen wide practical use. Projects based on construction of machine-checked formal proofs are now reaching an unprecedented scale, comparable to large software projects, which leads to new challenges in proof development and maintenance. Despite its increasing importance, the field of proof engineering is seldom considered in its own right; related theories, techniques, and tools span many fields and venues. This survey of the literature presents a holistic understanding of proof engineering for program correctness, covering impact in practice, foundations, proof automation, proof organization, and practical proof development.

Von diesen Beobachtungen ausgehend wird untersucht, welche Massnahmen der Lerntheorie im Umgang mit Verhaltensstörungen auf der Unterstufe zielführend sind und wie diese korrekt umgesetzt werden können. Dazu wurden Methoden der klassischen Lerntheorien anhand der qualitativen Inhaltsanalyse zusammengetragen und die Ergebnisse in Hinblick auf das heilpädagogische Arbeitsfeld interpretiert.
 Es hat sich gezeigt, dass in der Unterstufe hauptsächlich Methoden des operanten Konditionierens zielführend sind. Dabei müssen jedoch eine Vielzahl an Kriterien beachtet werden und die Massnahmen müssen stets individuell auf das Kind angepasst werden. Von Massnahmen, welche die ganze Klasse betreffen, wird eher abgeraten.

title: A continuing medical education program based in high quality evidence to transfer knowledge and to improve practice for health care professionals
Creators: name: Moja, Lorenzo P.
Publisher: name: The Open University
Year: 2014

description: This Doctoral of Philosophy program aimed to evaluate an initiative to foster knowledge translation through a national, interactive, and distant continuing education program based on an evidence based medicine point-of-care information service. It further explored the quality of the contents used in ECCE as compared to its market competitors (i.e. other evidence-based practice point-ofcare services). Our randomised controlled trial of nearly 200 physicians revealed little evidence for a difference in the health care knowledge of physicians who were exposed to versus those who were not exposed to contents derived from a point-of-care service. These results suggest that changes in behaviours, a direct consequence of changes in knowledge, may be difficult to obtain or might not be attainable at all, at least when a single continuing medical education program is implemented for short time period. In terms of determining the best available online resources among the 18 authoritative point-of-care services for guidance in clinical decision making that were assessed, only a minority satisfied the quality criteria (coverage of medical conditions, editorial quality, evidence-based methodology, and speed of updating), with none excelling in all. Publishers should continue to invest in the development of such products and improve their efficient use in continuing educational programs. These results might influence how international research and editorial groups that advocate evidence-based decision-making and evidence syntheses think about dissemination.

description: Kai Liu's thesis explores the concept of hybridity in art, examining the interplay between different artistic mediums and cultural paradigms. Through the analysis of two pivotal series, Near, So Far and Neither Mountains nor Water, this document delves into the phenomenon and application of hybrid art forms. The thesis highlights two aspects of hybridization: the fusion of printmaking and painting into a composite medium and the integration of traditional Chinese painting concepts with Western abstract art. Liu's work is a reflective dialogue between natural environments and internal contemplation, and it sublimates art traditions and artistic media. This thesis support document demonstrates Liu's creative strategy during his MFA studies at Emily Carr University, offering fresh perspectives on art and cultural identity.

Matrix metalloproteinases, inflammation, and matrix remodeling in coxsackievirus-induced myocarditis
Creators: name: Cheung, Caroline Tsui Yee
Publisher: name: University of British Columbia
Year: 2011

description: Myocarditis, or inflammation and injury of the heart muscle, induced by infection with coxsackievirus B3 (CVB3) is believed to lead to longterm heart disorders. Under pathological conditions, dysregulation of cardiac extracellular matrix (ECM) turnover results in maladaptive remodeling, progression of disease, and depressed cardiac function. The mechanisms by which this ECM alteration occurs are unclear, but inflammatory cells may be involved as secretors of matrix metalloproteinases (MMPs), cytokines, and growth factors that regulate ECM homeostasis. I hypothesize that MMPs play important roles in viral myocarditis. These enzymes degrade interstitial molecules, but they also regulate the immune system via modulation of cytokines and growth factors. To investigate the proposed hypothesis, I first examined the expression profile of MMP-2, MMP-8, MMP-9, MMP-12, and the tissue inhibitor of metalloproteinases (TIMPs), at key milestones in the evolution of myocarditis using a mouse model. To further explore the mechanisms, I infected MMP-8, MMP-9, and MMP-12 knockout mice, and examined how these deficiencies affected the immune response and matrix remodeling. Lastly, I inhibited the 4-1BB pathway, a major T-lymphocyte co-stimulatory molecule, to examine the synergy between the immune response and matrix remodeling. Following CVB3 infection, increased MMP-2, MMP-9, and MMP-12 expression was detected with corresponding decreases in TIMP expression, suggesting that an imbalance in MMPs and their inhibitors may result in increased protease activity. To examine the roles of the individual MMPs during CVB3 infection, I infected mice lacking MMP-8, MMP-9, or MMP-12. Following viral infection, mice deficient in MMP-12 and MMP-9 experienced increased viral titers and tissue injury while MMP-8 knockout mice showed minimal differences as compared to controls. The mechanisms by which the MMPs operate may be in ECM remodeling, but also modulation of the immune response, notably T-cells. In order to determine the effect of the immune response on matrix remodeling, I inhibited the 4-1BB receptor, a major T-cell stimulatory pathway, and observed a decrease in inflammation and matrix remodeling, while MMP-12 was decreased, in association with an improvement in cardiac function. My results suggest that MMPs may play crucial roles in CVB3 infection through their immune modulation and matrix remodeling activities.

description: Policy interventions aiming to boost the impacts of migration on development in communities of origin must take into account the less direct, less visible and often underestimated effects.

Key Takeaways

Beyond financial remittances, migration can shape communities of origin through the changing of social norms and values, including girls’ school enrolment.

The effects of migration can result in both beneficial and adverse development outcomes. 

Policy makers need to monitor the diverse effects of migration at the local level in order to support the positive effects, while mitigating possible negative effects.

description: Doublesex (Dsx) has a conserved function in controlling sexual morphological differences in insects, but our knowledge of its role in regulating sexual behaviour is primarily limited to Drosophila. Here, we show with the parasitoid wasp Nasonia vitripennis that males whose Dsx gene had been silenced (NvDsx-i) underwent a three-level pheromonal feminization: (i) NvDsx-i males were no longer able to attract females from a distance, owing to drastically reduced titers of the long-range sex pheromone. (ii) NvDsx-i males were courted by wild-type males as though they were females, which correlated with a lower abundance of alkenes in their cuticular hydrocarbon (CHC) profiles. Supplementation with realistic amounts of synthetic (Z)-9-hentriacontene (Z9C31), the most significantly reduced alkene in NvDsx-i males to NvDsx-i males interrupted courtship by wild-type conspecific males. Supplementation of female CHC profiles with Z9C31 reduced courtship and mating attempts by wild-type males. These results prove that Z9C31 is crucial for sex discrimination in N. vitripennis. (iii) Nvdsx-i males were hampered in eliciting female receptivity and thus experienced severely reduced mating success, suggesting that they are unable to produce the to-date unidentified oral aphrodisiac pheromone reported in N. vitripennis males. We conclude that Dsx is a multi-level key regulator of pheromone-mediated sexual communication in N. vitripennis.

We provide upper bounds for the Kodaira dimension of $\overline{\mathcal{M}}_{12,8}$ and $\overline{\mathcal{M}}_{16}$. We also show that the moduli of $(4g+5)$-pointed hyperelliptic curves $\mathcal{H}_{g,4g+5}$ is uniruled. Together with a recent result of Schwarz, this concludes the Kodaira classification for moduli of pointed hyperelliptic curves.

title: Exploring the use of qualitative social psychology in political science : discursive themes of an 18-24 cohort shaping their propensity to vote
Creators: name: Cole, Mark Clifford
Publisher: name: The Open University
Year: 2016

description: This thesis explores the use of qualitative social psychology in political science. The reason for conducting the research was the realisation that research within political science was dominated by quantitative realist methodologies and that existing qualitative research methods were ill-equipped to accommodate a linguistic interpretation of events. This thesis does not necessarily aim to supplant existing methodologies rather it asks how qualitative social psychology could compliment and facilitate existing methodological approaches. Qualitative social psychology is increasingly underpinned by social constructionism (Willig, 2001); that meaning is based on perspectives and that through their use of language individuals constantly make and remake the social (Burr, 2003; 2015). This methodology is relativistic. It suggests that meaning is specific and relative to social, cultural and historical moments (Parker, 1998) and draws on interpretivism suggesting that unlike in the hard sciences truth and evidence of social issues such as poverty is dependent on the interpretation by people (Schwandt, 2003). The thesis will use a constructionist thematised method to exemplify this approach. This method shares common ground with a range of methods used in qualitative social psychology that builds on initial thematised coding and consequently may lead to a broader understanding of the possibilities of using this approach in political science. To explore the possibilities of using qualitative psychology the thesis considered changes in attitudes to voting of the 18-24 cohort in the UK. The turnout of this cohort at general elections has declined since the 1992 general election and this has been problematic to explain using existing political science methodologies. A group of forty participants that might have typically taken part in a study investigating this topic were recruited. These were group interviewed and their talk was transcribed and then analysed to identify discursive codes and themes.

description: Changing climate is increasing the risk of wildfires. As temperatures continue to soar in the future, scientists warn that extreme fires will become more common. Meaningful early warning forecasts, early identification and tracking as well as effective response are of paramount importance to save lives and contain environmental damage. The EU-funded SAFERS project will develop a complex emergency management system capable of acting along the whole emergency management cycle, thanks to the coupled use of heterogeneous Big Data, advanced models, and AI. Earth Observation data from Copernicus and GEOSS will be the primary data source, which will be combined with data from social media, smoke detectors, and mobile applications. This will allow first responders, citizens and decision makers to generate new and more accurate information, enhancing our society's resilience against wildfires.
description: The files uploaded in the current package contain the following types of mapping related to wildfire events monitored within the SAFERS project:
- Burned area delineation: Outlines the extent of areas affected by the wildfire.
- Smoke and active fire delineation: Captures real-time fire front data and smoke dispersion data.
- Impact estimation: Assesses the damage and impact caused by the wildfire.
- Severity estimation: Evaluate the intensity and potential consequences of the fire.

description: Although life-history trade-offs are central to life-history evolution, their mechanistic basis is often unclear. Traditionally, trade-offs are understood in terms of competition for limited resources among traits within an organism, which could be mediated by signal transduction pathways at the level of cellular metabolism. Nevertheless, trade-offs are also thought to be produced as a consequence of the performance of one activity generating negative consequences for other traits, or be the result of genes or pathways that simultaneously regulate two life-history traits in opposite directions (antagonistic pleiotropy), independent of resource allocation. Yet, examples of genes with antagonistic effects on life-history traits are limited. This study provides direct evidence for a gene—RLS1, that is involved in increasing survival in nutrient-limiting environments at a cost to immediate reproduction in the single-celled photosynthetic alga, Chlamydomonas reinhardtii. Specifically, we show that RLS1 mutants are unable to properly suppress their reproduction in phosphate-deprived conditions. Although these mutants have an immediate reproductive advantage relative to the parental strain, their long-term survival is negatively affected. Our data argue that RLS1 is a bona fide life-history trade-off gene that suppresses immediate reproduction and ensures survival by downregulating photosynthesis in limiting environments, as part of the general acclimation response to nutrient deprivation in photosynthetic organisms.

description: We have observed three clusters at z~0.7, of richness comparable to the low redshift sample of Butcher & Oemler (BO), and determined their fraction of blue galaxies. When adopting the standard error definition, two clusters have a low blue fraction for their redshifts, whereas the fraction of the third one is compatible with the expected value. A detailed analysis of previous BO-like studies that adopted different definitions of the blue fraction shows that the modified definitions are affected by contaminating signals: colour segregation in clusters affects blue fractions derived in fixed metric apertures, differential evolution of early and late type spirals potentially affects blue fractions derived with a non standard choice of the colour cut, the younger age of the Universe at high redshift affects blue fractions computed with a colour cut taken relatively to a fixed non evolving colour. Adopting these definitions we find largely varying blue fractions. This thorough analysis of the drawbacks of the different possible definitions of the blue fraction should allow future studies to perform measures in the same scale. Finally, if one adopts a more refined error analysis to deal with BO and our data, a constant blue fraction with redshift cannot be excluded, showing that the BO effect is still far from being detected beyond doubt.

description: Cascading large-amplitude bursts in neural activity, termed avalanches, are thought to provide insight into the complex spatially distributed interactions in neural systems. In human neuroimaging, for example, avalanches occurring during resting-state show scale-invariant dynamics, supporting the hypothesis that the brain operates near a critical point that enables long range spatial communication. In fact, it has been suggested that such scale-invariant dynamics, characterized by a power-law distribution in these avalanches, are universal in neural systems and emerge through a common mechanism. While the analysis of avalanches and subsequent criticality is increasingly seen as a framework for using complex systems theory to understand brain function, it is unclear how the framework would account for the omnipresent cognitive variability, whether across individuals and/or tasks. To address this, we analyzed avalanches in the EEG activity of healthy humans during rest as well as two distinct task conditions that varied in cognitive demands and produced behavioral measures unique to each individual. In both rest and task conditions we observed that avalanche dynamics demonstrate scale-invariant characteristics, but differ in their specific features, demonstrating individual variability. Using a new metric we call normalized engagement, which estimates the likelihood for a brain region to produce high-amplitude bursts, we also investigated regional features of avalanche dynamics. Normalized engagement showed not only the expected individual and task dependent variability, but also scale-specificity that correlated with individual behavior. Our findings expand our understanding of avalanche features and are supportive of the emerging theoretical idea that the dynamics of an active human brain operate close to a critical-like region and not a singular critical-state.

description: This article defines and proves basic properties of the standard quantum circuit model of computation. The model is developed abstractly in close analogy with (classical) deterministic and probabilistic circuits, without recourse to any physical concepts or principles. It is intended as a primer for theoretical computer scientists who do not know--and perhaps do not care to know--any physics.

description: Breadfruit, a versatile tree crop predominately used for its nutritious and starchy fruit, is commonly consumed among West Indian people. Because of its seasonality and shortshelf life, there is a need for an economical method of extending its availability. One such process is through the production of breadfruit flour. However, detailed information is needed on the nutrient profile of the flour. More research is needed in order to determine whether there are cultivar differences; previous research has been limited to one un-named cultivar at one stage of maturity. The objective of this study was to determine the influence of cultivar and maturity on the yield and nutrient composition of breadfruit flour. Four breadfruit cultivars, Jackson Macca (JM), Kashee Bread (KB), Local White (LW) and Local Yellow (LY), growing in the germplasm collection of the University Field Station, Valsayn, Trinidad, were evaluated for flour yield and nutrient composition. The fruits were harvested at the immature and mature stages. The flesh was sliced 5 mm thick, dried at 60° C for 24 hours, milled and sieved (0.60 mm). Proximate analyses were done in triplicate and according to the AOAC methods (1990). There were no significant differences in the fresh weights of the four selected cultivars. However, there were significant differences (p<0.05) in yield, dry matter, ash, crude protein, ether extract, dietary fibre, carbohydrates, calcium, magnesium, and iron content of the breadfruit flours. Cultivar JM showed the highest yield (46.5±1.4%) in addition to the highest levels of crude protein (5.5±0.4 g/100 g), ether extract (1.6±0.1 g/100 g) and carbohydrates (71.7±0.3 g/100 g). There were significant differences between dry matter (91.8±0.3 g/100 g immature; 90.9±0.2 g/100 g mature) and carbohydrates (67.9±0.8 g/100 g immature; 69.9±0.4 g/100 g mature). This finding illustrates that as the fruit matures, there is an increase in moisture and in carbohydrate content. This increase may be partly due to metabolic water and the bulking up of starches and sugars within the fruit as it matures. The knowledge of the nutrient composition of breadfruit flour is necessary for the production of acceptable food products which satisfy the nutritional needs of consumers, leading to increased use of breadfruit and thereby contributing to sustainable agriculture and food security.

description: As Tunisia becomes a major border point for irregular migration it faces growing pressure to implement EU transit migration policies. Yet, these policies seem to have little effect on migration patterns and inadvertently impact the mobility of Tunisian nationals.

Key Takeaways

The Tunisian context exemplifies some of the major impacts of transit migration policies on nationals of transit countries across the European neighbourhood.

Amid high unemployment and political instability, migration aspirations are high among Tunisian nationals.

There is a rising number of Tunisian nationals travelling on irregular migration routes. Many are prevented from doing so regularly by EU transit migration measures.
