Morals of Precarity: Artistic Trajectories under the Orbán Regime of Hungary
Creators: name: Nagy, Kristóf

Publisher: name: Comparativ
Year: 2021

description: This article analyses the career path of young cultural producers in Hungary. We show how they navigate in the everyday life of the Orbán regime. We define the social and political formation emerging after 2010 as a form of semi-peripheral hegemony that supports certain factors of international capital and strengthens its allied local bourgeoisie. We investigate culture not merely as an ideological underpinning of this regime but also as a commodity that is integrated into its new economic mechanisms. By utilizing primary and secondary quantitative data as well as qualitative methods of interview and policy-analysis, we focus on how the hegemonic process of the Orbán regime mingles incorporation and exclusion. We outline Janus-faced cultural politics and a policy that rules the heteronomous pole of cultural production by an “economic rationality”, while more direct forms of “ideological control” are employed on the autonomous pole. By showing how the previous decade was characterized by a precarization of cultural work, we argue that current artistic careers are highly reliant either on incomes from the creative industry or on the sphere of social reproduction. As we conclude, this vulnerability can open a path for a certain authoritarian deepening under the COVID-19 crisis.

description: © Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License (CC BY-NC-ND 4.0). Over the past several years, parton distribution functions (PDFs) have become more precise. However there are still kinematic regions where more data are needed to help constrain global PDF extractions, such as the ratio of the sea quark distributions d¯/ū near the valence region. Furthermore, current measurements appear to suggest different high-x behaviors of this ratio. The W cross section ratio (W+/W−) is sensitive to the unpolarized quark distributions at large Q2 set by the W mass. Such a measurement can be used to help constrain the d¯/ū ratio. The STAR experiment at RHIC is well equipped to measure the leptonic decays of W bosons, in the midpseudorapdity range (|η| ≤ 1), produced in proton-proton collisions at √s = 500/510 GeV. At these kinematics STAR is sensitive to quark distributions near x of 0.16. STAR can also measure W+/W− in a more forward region ranging from 1.0 < η <1.5, which extends the sea quark sensitivity to higher x. RHIC runs from 2011 through 2013 have collected about 350 pb−1 of integrated luminosity, and an additional 350 pb−1 from the 2017 run. These proceedings will present preliminary results of the 2011-2013 W+/W− cross section ratio measurements. Additionally, the W/Z cross section ratio, differential and total W and Z cross sections are presented.
Beyond Prayer- Living in Communion with the Divine

description: Beyond Prayer – Living in Communion with the Divine challenges traditional views of prayer as a request-based practice. Rooted in Unified Theistic Naturalism (UTN), this paper reveals that true communion dissolves the separation between self and the Divine. When Presence is fully lived, prayer transforms from petition into participation. This work explores the limitations of conventional prayer, the evolution toward divine cadence, and the profound simplicity of living in continuous communion with the sacred now.

description: © 2019 Hollin et al. Purpose: Rare diseases present challenges for accessing patient populations to conduct surveys. Clinical Data Research Networks (CDRNs) offer an opportunity to overcome those challenges by providing infrastructure for accessing patients and sharing data. This study aims to demonstrate the feasibility of collecting patient preference information for a rare disease in a CDRN, using idiopathic pulmonary fibrosis as proof of concept. Patients and methods: Utilizing a cohort of idiopathic pulmonary fibrosis (IPF) patients across a CDRN, a discrete choice experiment was administered via electronic and paper methods to collect patient preference information about benefits and risks of two therapeutic options. Survey data were augmented with data from electronic health records and patient-reported outcome surveys. Results: Thirty-three patients completed the preference experiment. The amount of choice attributable to a benefit of slowing of decline in lung function was 36%. Improving efficacy in terms of lung function was 2.16 times as important as improving efficacy in terms of shortness of breath. In terms of side effects, decreasing risk of gastrointestinal problems was 2.6 times as important as decreasing risk of sun sensitivity and 2.4 times as important as decreasing risk of liver injury. In terms of benefit-risk trade-offs, improving efficacy in terms of lung function was 1.6 times as important as decreasing risk of gastrointestinal problems. Conclusion: This study used IPF as a proof of concept to demonstrate the feasibility of collecting patient preference information in a CDRN. The network was advantageous to the study of patient preferences. Future research should continue to explore pathways for the collection and use of patient preference information across networks. The power of consolidated collection efforts may lead to the ability to use preference data to inform decision-making at the regional, specialty, or individual encounter level.

The massive genomic data from The Cancer Genome Atlas (TCGA), including proteomics data from Clinical Proteomic Tumor Analysis Consortium (CPTAC), provides a unique opportunity to study cancer systematically. While most observations are made from a single type of genomics data, we apply big data analytics and systems biology approaches by simultaneously analyzing DNA amplification, mRNA and protein abundance. Using multiple genomic profiles, we have discovered widespread dosage compensation for the extensive aneuploidy observed in TCGA breast cancer samples. We do identify 11 genes that show strong correlation across all features (DNA/mRNA/protein) analogous to that of the well-known oncogene HER2 (ERBB2). These genes are generally less well-characterized regarding their role in cancer and we advocate their further study. We also discover that shRNA knockdown of these genes has an impact on cancer cell growth, suggesting a vulnerability that could be used for cancer therapy. Our study shows the advantages of systematic big data methodologies and also provides future research directions.
In Search of the Third Canon, or Cultural Policies of the Third Republic of Poland (1989–2020)
Creators: name: Czapliński, Przemysław
Publisher: name: Comparativ
Year: 2021

description: Culture in Poland after 1989 was managed with two different approaches. In the last decade of the twentieth century and in the beginning of the twenty-first century cultural policy was based on the dogma of self-financing culture. The second period was initiated by the right- wing government in 2005 and is still current politics. Here, cultural policy is based on the dogma of the self-sufficiency of national values. Both concepts result from the belief that the canon is empty but with different implications. In neoliberal practice, everyone has the right to have their own canon, while each canon matters only insofar as it leads to success in life. For a right-wing party, the canon should express national, not classical, values. In the first concept, culture is doomed to rapid commodification, in the second to nationalization. In the first period, culture was granted independence on the condition that artists earn their own living and, moreover, the bond-forming role of culture was neglected. In the second period, the state provides financial support to culture, but limits funding to nationalist initiatives, hence censoring expressions of independent art. The question to be asked: is there a third canon?

description: In this paper, we study the target tracking problem in wireless sensor networks (WSNs) using quantized sensor measurements under limited bandwidth availability. At each time step of tracking, the available bandwidth $R$ needs to be distributed among the $N$ sensors in the WSN for the next time step. The optimal solution for the bandwidth allocation problem can be obtained by using a combinatorial search which may become computationally prohibitive for large $N$ and $R$. Therefore, we develop two new computationally efficient suboptimal bandwidth distribution algorithms which are based on convex relaxation and approximate dynamic programming (A-DP). We compare the mean squared error (MSE) and computational complexity performances of convex relaxation and A-DP with other existing suboptimal bandwidth distribution schemes based on generalized Breiman, Friedman, Olshen, and Stone (GBFOS) algorithm and greedy search. Simulation results show that, A-DP, convex optimization and GBFOS yield similar MSE performance, which is very close to that based on the optimal exhaustive search approach and they outperform greedy search and nearest neighbor based bandwidth allocation approaches significantly. Computationally, A-DP is more efficient than the bandwidth allocation schemes based on convex relaxation and GBFOS, especially for a large sensor network.

description: © 2019 Pacheco et al. The Hoatzin (Opisthocomus hoazin) is the only extant member of the order Opisthocomiformes. This unique South American bird lives in the riparian lowland vegetation characteristic of the Amazon and Orinoco basins. Hoatzins nest in communal social units close to water bodies; they are strictly folivores being the only bird with pregastric fermentation in the crop. Because of the complex logistics involved in capturing this bird, there is a knowledge gap on its parasites. This study documents two distant lineages of haemosporidian parasites (Plasmodium spp.) in a juvenile and two adults sampled in the Cojedes state, Venezuela. Although negative by microscopy, the parasite identification was possible by using molecular methods. We estimated the phylogenetic relationships on the parasite cytochrome b (cytb, 480 bp) gene and the mitochondrial DNA. We found one of the parasites lineages in two individuals (nestling and adult), and the corresponding fragment of cytb was identical to a one found in Wood Stork (Mycteria americana) from Brazil. The other lineage, found in an adult, has an identity of 469 out of 478 bp (98%) with Plasmodium sp. GAL-2012 (isolate THAMB08) from Brazil. Although a morphological description of these parasites was not possible, this is the first molecular study focusing on Hoatzin haemosporidian parasites and the first documentation of Plasmodium infections in the Hoatzin from Venezuela. Furthermore, we reported microfilaria in two adults as well as hematological parameters for six individuals. Information on hematological parameters could contribute to establishing the necessary baseline to detect underlying conditions, such as infections, in this bird species.

description: This paper critically examines the ethical theories of Mary Aiken and her applications to digital crime scene investigations, alongside the transformative role of Artificial Intelligence (AI) in forensic analysis. AI, defined as the capability of computer systems to mimic cognitive functions such as learning, reasoning, and decision-making, has increasingly reshaped investigative methodologies (Goodfellow, Bengio, & Courville, 2016).Aiken’s contributions to cyberpsychology, which is an interdisciplinary field that explores the psychological impact of digital environments on human cognition and behavior it offers vital insights into the ethical complexities surrounding the collection, analysis, and preservation of digital evidence (Attrill-Smith et al., 2019).This paper applies Aiken’s theoretical framework to the ethical dilemmas faced by forensic investigators in an era of rapid technological advancement. Additionally, it explores AI’s potential to enhance the accuracy and efficiency of digital crime scene investigations, while critically assessing concerns related to privacy infringement, algorithmic bias, and the erosion of human accountability in automated decision-making.To provide empirical context, two case studies are examined one demonstrating AI’s capacity to augment forensic investigations positively and another highlighting its unintended adverse consequences.Ultimately, this research underscores the necessity of ethical vigilance and responsible AI integration in forensic science to balance investigative efficacy with the preservation of fundamental human rights.Keywords: Mary Aiken, ethical theories, digital crime scene investigation, artificial intelligence, digital forensics, cyberpsychology, privacy, algorithmic bias.
Collective memoir as public pedagogy : a study of narrative, writing, and memory

Publisher: name: University of British Columbia

description: This dissertation investigates the ways in which literary practices can be used to generate learning. It is guided by the following research questions: • How can the processes of writing memoir change our perceptions of the past? • How can these writing processes be theorized and understood as educational events? Data are provided by two research groups, one composed of seven older lesbians and one composed of 26 older LGBT individuals known as the Queer Imaging & Riting Kollective for Elders (Quirk-e), an arts-engaged community group with whom I have worked for the last five years. In the first case, practices of close reading, memoir writing, and discussion were conducted, and discussions were digitally recorded and transcribed. In the second, data are provided by the artwork produced by the members of Quirk-e and by my reflections upon my practices as their writer-in-residence. Data are also provided by my own creative compositions, which serve as interludes between the standalone papers that comprise the body of the dissertation. Data are analyzed through critical and literary interpretations, autobiographical and narrative methods, and conceptual inquiry. I conclude that unpacking memories and life experiences by writing memoir can lead to more nuanced understandings of the self and the culture in which it has developed. I also conclude that such learning can be assisted by paying close attention to specific memories, using processes of association, and then by considering the emergent genres and structures that frame the work as it is revised. Finally, I consider my practices as a public pedagogue in the light of these reflections, to begin to consider how teaching might be usefully considered as a form of artistic composition, with its own emergent genres.
The Transformation of Urban Cultural Policy in East Germany and Poland: The Cases of Leipzig and Krakow
Creators: name: Höpel, Thomas
Publisher: name: Comparativ
Year: 2021

description: This article analyses the transformation of cultural policies in East Germany and Poland after the end of state socialism by studying the developments in the two cities Krakow and Leipzig. As economic, infrastructural, and cultural centres, Krakow as well as Leipzig had a prominent position within the national urban system and they were representative of the principal evolution in big East German and Polish cities after 1989. The contribution studies first the personal and structural developments in the cultural realm after the radical social and political changes of 1989. Secondly it discusses the plans for the strategic reorientation of urban culture and their impact on the cities’ cultural institutions and landscape. The third part of the article focuses on the role of the state in the process of transforming urban cultural institutions. The comparative analysis shows that the urban actors promoted culture as an economic factor in both cases and that the reorientation of urban cultural policy was linked to local traditions as well as to Western European models. Culture was seen as an instrument of integration that should bring together the society in the two cities. In addition, a new quality of transnational and international cooperation between cities in the field of culture emerged.

Art from the GDR: Brand Ambassador of Socialism at First, then Suddenly a Wreckage of History… East German Art Exhibitions in the USA between 1989 and 1991.

Publisher: name: Comparativ

description: Today, the visual arts play an important role in the presentation of companies (advertising), municipalities (location marketing), and nations (nation branding). Since its foundation, the GDR tried to improve its international reputation with the help of visual arts. Nevertheless, it was not until its recognition by the Western countries that the cultural exchange with the USA, Great Britain, and other Western European countries could develop without obstacles. At the same time, the dogma of Socialist Realism dissolved during the 1970s and a wider stylistic range in art was tolerated in the GDR. In the 1980s, it became possible for art from the GDR to be shown even in representative museums in Great Britain, France, and the USA. However, it was in the most successful period of its foreign cultural policy that the GDR collapsed. Its art and artists were touring abroad still in the fall and winter of 1989/90, and they were left behind like wreck- age and shipwreck victims of history: suddenly, they now were on their own; the state and the system they were supposed to represent did no longer exist. The article examines three trave- ling exhibitions of East German art that toured the United States between 1989 and 1991 and focuses on the then completely changed working conditions of East German artists.

description: Software obfuscation is a crucial technology to protect intellectual property and manage digital rights within our society. Despite its huge practical importance, both commercial and academic state-of-the-art obfuscation methods are vulnerable to a plethora of automated deobfuscation attacks, such as symbolic execution, taint analysis, or program synthesis. While several enhanced obfuscation techniques were recently proposed to thwart taint analysis or symbolic execution, they either impose a prohibitive runtime overhead or can be removed in an automated way (e.g., via compiler optimizations). In general, these techniques suffer from focusing on a single attack vector, allowing an attacker to switch to other, more effective techniques, such as program synthesis. In this work, we present Loki, an approach for software obfuscation that is resilient against all known automated deobfuscation attacks. To this end, we use and efficiently combine multiple techniques, including a generic approach to synthesize formally verified expressions of arbitrary complexity. Contrary to state-of-the-art approaches that rely on a few hardcoded generation rules, our expressions are more diverse and harder to pattern match against. Even the most recent state-of-the-art research on Mixed-Boolean Arithmetic (MBA) deobfuscation fails to simplify them. Moreover, Loki protects against previously unaccounted attack vectors such as program synthesis, for which it reduces the success rate to merely 19%. In a comprehensive evaluation, we show that our design incurs significantly less overhead while providing a much stronger protection level compared to existing works.
Biocompatibility studies of fluorescent diamond particles-(Nv)~800nm (part v): In vitro kinetics and in vivo localization in rat liver following long-term exposure

description: © 2019 Gerstenhaber et al. Background: We recently reported on long-term comprehensive biocompatibility and biodistribution study of fluorescent nanodiamond particles (NV)-Z-average 800nm (FNDP- (NV)) in rats. FNDP-(NV) primary deposition was found in the liver, yet liver function tests remained normal. Purpose: The present study aimed to gain preliminary insights on discrete localization of FNDP-(NV) in liver cells of the hepatic lobule unit and venous micro-vasculature. Kinetics of FDNP-(NV) uptake into liver cells surrogates in culture was conducted along with cell cytokinesis as markers of cells' viability. Methods: Preserved liver specimens from a pilot consisting of two animals which were stained for cytoskeletal elements (fluorescein-isothiocyanate-phalloidin) were examined for distribution of FNDP-(NV) by fluorescent microscopy (FM) and Confocal-FM (CFM) using near infra-red fluorescence (NIR). Hepatocellular carcinoma cells (HepG-2) and human umbilical vein endothelial cells (HUVEC) were cultured with FNDP-(NV) and assayed for particle uptake and location using spectrophotometric technology and microscopy. Results: HepG-2 and HUVEC displayed rapid (<30 mins) onset and concentration-dependent FNDP-(NV) internalization and formation of peri-nuclear corona. FM/CFM of liver sections revealed FNDP-(NV) presence throughout the hepatic lobules structures marked by spatial distribution, venous microvascular spaces and parenchyma and non-parenchyma cells. Conclusion: The robust presence of FNDP-(NV) throughout the hepatic lobules including those internalized within parenchyma cells and agglomerates in the liver venous microcirculation were not associated with macro or micro histopathological signs nor vascular lesions. Cells cultures indicated normal cytokinesis in cells containing FNDP-(NV) agglomerates. Liver parenchyma cells and the liver microcirculation remain agnostic to presence of FNDP-(NV) in the sinusoids or internalized in the hepatic cells.

description: Research on visualizations of our growing personal data collections thus far has been predominantly geared towards behaviour-change. However, this focus may have overlooked opportunities for other meaningful ways to relate to personal data. People engage in a variety of activities to foster self-understanding, identity development, and strengthen their relationships. Such practices include writing diaries, connecting to others through personal stories, and collecting reminders of important accomplishments, events, and relationships. These forms of self-reflection, reminiscing, and self-expression can help us experience our lives as meaningful. The potential of visualizations for ``amplifying cognition'' and communicating data make them a promising means for supporting a wider range of self-reflective and expressive practices that have so far been little explored in visualization. In this thesis, I study the potential of visualizations of personal data for self-reflection and expression. As part of this research, I derive conceptual considerations for personal visualizations from research on everyday narrative practices, autobiographical memory, and the use of mementos. By relating and applying findings from these areas to visualization, I contribute design considerations for visualizations that support personal expression and reflection. I further explore example visualization approaches that address these design considerations. I contribute a visualization technique for reminiscing, and a system that allows people to create, reflect on, and share visualization mementos. I further describe a paradigm and construction kit that allow people without prior visualization, design or programming skills to construct personal visualizations. Finally, I present findings from qualitative studies that explore how individuals create and use visualizations for personal reflection and expression. The first investigation explores techniques for conveying subjective perspectives based on an analysis of narrative visualizations. The second study focuses on people's experiences with creating visualization mementos. The last study examines how people construct and reflect on personal visualizations in their domestic environment. These investigations allow me to validate and refine the proposed design considerations, evaluate the developed visualization approaches and point to interesting directions for future research. I hope that this research will contribute to the development of visualizations that encourage individual meaning-making with personal data by supporting diverse reflective and expressive practices.

description: We estimate the vector interaction strength of the Polyakov-Nambu-Jona-Lasinio (PNJL) parametrizations, assuming that its transition curves should be as close as possible of the recently studied RMF-PNJL hadron-quark phase diagrams. Such diagrams are obtained matching relativistic mean-field hadronic models, and the PNJL quark ones. By using this method we found for the magnitude of the vector interaction, often treated as a free parameter, a range of 7.66 GeV$^{-2}\lesssim G_V \lesssim 16.13$ GeV$^{-2}$, or equivalently, $1.52 \lesssim G_V/G_s \lesssim 3.2$, with $G_s$ being the scalar coupling constant of the model. These values are compatible but restricts the range of 4 GeV$^{-2}\lesssim G_V \lesssim 19$ GeV$^{-2}$, recently obtained from lattice QCD data through a different mean-field model approach.

Transformation East Fuels Transformation West: Tendencies in Cultural Politics and Its Transformations in the Process of German Unification
Creators: name: Ibs, Torben
Publisher: name: Comparativ
Year: 2021

description: The unification of the two German states in 1990 presented great challenges to cultural pro- fessionals in the former GDR. In order to maintain and modernize the existing theatres their organizational forms had to be adjusted and new economic models had to be implemented. Since the Länder were not willing to or able to meet the new challenges with their own resources, the Federal Government generated investments on its own according to article 35 of the Einigungsvertrag, thus shaping a new system of cultural politics. Theatres were a field of experimentation to seek new and more autonomous models of admin- istration. This was especially proposed by the advocates of New Public Management that had not been applied to the cultural sector until the early 1990s. Mergers and regional cooperation created new formations of stakeholders. In this process, each of the Länder in East Germany followed its own path, especially focusing on the distribution of funding between the local authorities and the Länder. Finally, the transformations in East Germany cannot be seen as a singular process but as a blueprint to foster neo-liberal reformations of structures throughout the 1990s in West Germany as well.

Berlin’s Theatre Landscape after 1989: Cultural Policy Strategies and Multi-Level Transformations

description: After 1989, cultural policy makers in Berlin faced the challenge of reorganizing the city’s dual cultural structure in the context of multi-level transformations. This article analyzes their strategies, using the example of the funding and reprofiling of the city’s theatre landscape. The integration of East German theatres into the federal German theatre landscape did not happen solely by adapting them to western structures. Instead, all of Berlin’s theatres were reviewed to determine whether they could still assume an important function for the reinvention of the city as the capital of unified Germany and as a cultural metropolis of international importance. At the same time, the funding of the capital city’s cultural infrastructure had to be renegotiated between the federal and state governments, shifting toward permanent and direct federal funding for the cultural sector. Moreover, cultural policy concepts underwent profound changes throughout the 1990s, as culture was gradually discovered as one of the city’s central economic resources.

description: Recent proposals have been advanced to apply imaging air Cherenkov telescope arrays to stellar intensity interferometry (SII). Of particular interest is the possibility of model-independent image recovery afforded by the good (u, v)-plane coverage of these arrays, as well as recent developments in phase retrieval techniques. The capabilities of these instruments used as SII receivers have already been explored for simple stellar objects, and here the focus is on reconstructing stellar images with non-uniform radiance distributions. We find that hot stars (T > 6000 K) containing hot and/or cool localized regions (T \sim 500 K) as small as \sim 0.1 mas can be imaged at short wavelengths (λ = 400 nm).

description: We study the complexity of approximating the number of answers to a small query \varphi in a large database D. We establish an exhaustive classification into tractable and intractable cases if \varphi is a conjunctive query possibly including disequalities and negations: - If there is a constant bound on the arity of \varphi, and if the randomised Exponential Time Hypothesis (rETH) holds, then the problem has a fixed-parameter tractable approximation scheme (FPTRAS) if and only if the treewidth of \varphi is bounded. - If the arity is unbounded and \varphi does not have negations, then the problem has an FPTRAS if and only if the adaptive width of \varphi (a width measure strictly more general than treewidth) is bounded; the lower bound relies on the rETH as well. Additionally we show that our results cannot be strengthened to achieve a fully polynomial randomised approximation scheme (FPRAS): We observe that, unless NP =RP, there is no FPRAS even if the treewidth (and the adaptive width) is 1. However, if there are neither disequalities nor negations, we prove the existence of an FPRAS for queries of bounded fractional hypertreewidth, strictly generalising the recently established FPRAS for conjunctive queries with bounded hypertreewidth due to Arenas, Croquevielle, Jayaram and Riveros (STOC 2021).

phylogenomics

description: © The Author(s) 2019. New species arise from pre-existing species and inherit similar genomes and environments. This predicts greater similarity of the tempo of molecular evolution between direct ancestors and descendants, resulting in autocorrelation of evolutionary rates in the tree of life. Surprisingly, molecular sequence data have not confirmed this expectation, possibly because available methods lack the power to detect autocorrelated rates. Here, we present a machine learning method, CorrTest, to detect the presence of rate autocorrelation in large phylogenies. CorrTest is computationally efficient and performs better than the available state-of-the-art method. Application of CorrTest reveals extensive rate autocorrelation in DNA and amino acid sequence evolution of mammals, birds, insects, metazoans, plants, fungi, parasitic protozoans, and prokaryotes. Therefore, rate autocorrelation is a common phenomenon throughout the tree of life. These findings suggest concordance between molecular and nonmolecular evolutionary patterns, and they will foster unbiased and precise dating of the tree of life.

description: © 2019 El Boustani, De Stefano, Caligiuri, Mouawad, Granchi, Canzonieri, Tuccinardi, Giordano and Rizzolio. PIN1 is a member of a family of peptidylprolyl isomerases that bind phosphoproteins and catalyze the rapid cis–trans isomerization of proline peptidyl bonds, resulting in an alteration of protein structure, function, and stability. PIN1 is overexpressed in human cancers, suggesting it promotes tumorigenesis, but depending on the cellular context, it also acts as a tumor suppressor. Here, we review the role of PIN1 in cancer and the regulation of PIN1 expression, and catalog the single nucleotide polymorphisms, and mutations in PIN1 gene associated with cancer. In addition, we provide a 3D model of the protein to localize the mutated residues.

description: Using computer simulations we show that lipid membranes can mediate linear aggregation of spherical nanoparticles binding to it for a wide range of biologically relevant bending rigidities. This result is in net contrast with the isotropic aggregation of nanoparticles on fluid interfaces or the expected clustering of isotropic insertions in biological membranes. We present a phase diagram indicating where linear aggregation is expected, and compute explicitly the free energy barriers associated with linear and isotropic aggregation. Finally, we provide simple scaling arguments to explain this phenomenology.

description: Graph is an important data representation ubiquitously existing in the real world. However, analyzing the graph data is computationally difficult due to its non-Euclidean nature. Graph embedding is a powerful tool to solve the graph analytics problem by transforming the graph data into lowdimensional vectors. These vectors could also be shared with third parties to gain additional insights of what is behind the data. While sharing graph embedding is intriguing, the associated privacy risks are unexplored. In this paper, we systematically investigate the information leakage of the graph embedding by mounting three inference attacks. First, we can successfully infer basic graph properties, such as the number of nodes, the number of edges, and graph density, of the target graph with up to 0.89 accuracy. Second, given a subgraph of interest and the graph embedding, we can determine with high confidence that whether the subgraph is contained in the target graph. For instance, we achieve 0.98 attack AUC on the DD dataset. Third, we propose a novel graph reconstruction attack that can reconstruct a graph that has similar graph structural statistics to the target graph. We further propose an effective defense mechanism based on graph embedding perturbation to mitigate the inference attacks without noticeable performance degradation for graph classification tasks.

description: The overall objective of the research reported in this dissertation was to investigate biological factors underlying ecological specialization in Canadian plant-pollinator communities. Using a combination of fieldwork and the analysis of previously collected data, my research determined that landscape degradation led to observed local-scale differences in the prevalence of ecologically specialized clades of plants and pollinators in Canadian ecosystems. Through ecological and phylogenetic community analysis, I found that the alteration in community composition increases the prevalence of zygomorphic clades in the more degraded zones. Thus, plant community composition in disturbed areas favours the persistence of ecologically specialized groups (notably nitrogen fixers) that may enhance soil conditions. The prevalence of particular clades of pollinators in the two different habitats across Canada is partly due to the environmental tolerances of certain pollinator clades. Bombus clade comprised a higher proportion of prairie bees, whereas assemblages in Garry oak sites exhibited higher representation from solitary bees (e.g., Osmia, Andrena, Ceratina). Likewise, pollinator traits associated with areas that had more precipitations was soil nesting and traits related to areas that exhibited high temperatures were cavity-nesting. I identified specific cases of reciprocal specialization in plant-pollinator interactions as well as selective environmental occupancy of ecologically specialized clades. These findings can inform conservation efforts to maintain adequate pollination services to plant communities. Although disturbance interactions remained consistent in the number of reciprocal specialization cases, I hypothesize plant-pollinator interactions in prairie grassland systems in Alberta exhibit more interesting cases of specialization than previously thought.

The work is made available under the Creative Commons CC0 public domain dedication. African American men are disproportionately affected by, not only HIV/AIDS, but also chronic non-communicable diseases. Despite the known benefits of physical activity for reducing chronic non-communicable diseases, scant research has identified factors that may influence physical activity in this population. A growing literature centers on the syndemic theory, the notion that multiple adverse conditions interact synergistically, contributing to excess morbidity. This secondary data analysis examined two primary questions: whether syndemic conditions prospectively predicted physical activity, and whether, consistent with the syndemic theory, syndemic conditions interacted to predict physical activity. Participants were 595 African American men who have sex with men (MSM), a population underrepresented in health research, enrolled in a health-promotion intervention trial from 2008–2011. We used generalized-estimating-equations models to test the associations of syndemic conditions and resilience factors measured pre-intervention to self-reported physical activity 6 and 12 months post-intervention. As hypothesized, reporting more syndemic conditions pre-intervention predicted reporting less physical activity 6 and 12 months post-intervention, adjusting for the intervention. However, contrary to the syndemic theory, we did not find evidence for the interaction effects of syndemic conditions in predicting physical activity. Receiving high school education and having greater social network diversity predicted more physical activity whereas older age predicted less physical activity. To our knowledge, this is the first study to examine the syndemic theory in relation to physical activity. Although reporting a greater number of syndemic conditions was related to reduced physical activity, there was no evidence for synergy among syndemic conditions.
Orbital-Angular-Momentum Based Origin of Rashba-Type Surface Band Splitting

description: We propose that existence of local orbital angular momentum (OAM) on the surfaces of high-Z materials play a crucial role in the formation of Rashba-type surface band splitting. Local OAM state in a Bloch state produces asymmetric charge distribution (electric dipole). Presence of surface electric field aligns the electric dipole and results in chiral OAM states and the relevant Rashba- type splitting. Therefore, the band splitting originates from electric dipole interaction, not from the Zeeman splitting as proposed in the original Rashba picture. The characteristic spin chiral structure of Rashba states is formed through the spin-orbit coupling and thus is a secondary effect to the chiral OAM. Results from first principles calculations on a single Bi layer under an external electric field verify the key predictions of the new model, including the direction of the spin textures which is predicted to be in opposite direction in the Rashba picture.
