description: We present a kinetic theory of two-dimensional decaying turbulence in the context of two-body and three-body vortex merging processes. By introducing the equations of motion for two or three vortices in the effective noise due to all the other vortices, we demonstrate analytically that a two-body mechanism becomes inefficient at low vortex density $n\ll 1$. When the more efficient three-body vortex mergings are considered {(involving vortices of different signs)}, we show that $n\sim t^{-ξ}$, with $ξ=1$. We generalize this argument to three-dimensional geostrophic turbulence, finding $ξ=5/4$, in excellent agreement with direct Navier-Stokes simulations [J.\,C. McWilliams \emph{et al.}, J. Fluid Mech. {\bf 401}, 1 (1999)].

description: We investigate the building of unified models that can predict the matter-density power spectrum and the two-point correlation function from very large to small scales, being consistent with perturbation theory at low $k$ and with halo models at high $k$. We use a Lagrangian framework to re-interpret the halo model and to decompose the power spectrum into "2-halo" and "1-halo" contributions, related to "perturbative" and "non-perturbative" terms. We describe a simple implementation of this model and present a detailed comparison with numerical simulations, from $k \sim 0.02$ up to $100 h$Mpc$^{-1}$, and from $x \sim 0.02$ up to $150 h^{-1}$Mpc. We show that the 1-halo contribution contains a counterterm that ensures a $k^2$ tail at low $k$ and is important not to spoil the predictions on the scales probed by baryon acoustic oscillations, $k \sim 0.02$ to $0.3 h$Mpc$^{-1}$. On the other hand, we show that standard perturbation theory is inadequate for the 2-halo contribution, because higher order terms grow too fast at high $k$, so that resummation schemes must be used. We describe a simple implementation, based on a 1-loop "direct steepest-descent" resummation for the 2-halo contribution that allows fast numerical computations, and we check that we obtain a good match to simulations at low and high $k$. Our simple implementation already fares better than standard 1-loop perturbation theory on large scales and simple fits to the power spectrum at high $k$, with a typical accuracy of 1% on large scales and 10% on small scales. We obtain similar results for the two-point correlation function. However, there remains room for improvement on the transition scale between the 2-halo and 1-halo contributions, which may be the most difficult regime to describe.

description: Electron interferometry via phase-contrast microscopy, holography, or picodiffraction can provide a direct visualization of the static electric and magnetic fields inside or around a material at subatomic precision, but understanding the electromagnetic origin of light-matter interaction requires time resolution as well. Here, we demonstrate that pump-probe electron diffraction with all-optically compressed electron pulses can capture dynamic electromagnetic potentials in a nanophotonic material with sub-light-cycle time resolution via centrosymmetry-violating Bragg spot dynamics. The origin of this effect is a sizable quantum mechanical phase shift that the electron de Broglie wave obtains from the oscillating electromagnetic potentials within less than 1 fs. Coherent electron imaging and scattering can therefore reveal the electromagnetic foundations of light-matter interaction on the level of the cycles of light.
Factors affecting the efficacy of biodiversity conservation in tropical protected areas : a case study in Xishuangbanna, southwestern China
Creators: name: Chen, Cheng

Year: 2017

description: Protected areas have long been considered the backbone of biodiversity conservation strategies. However, whether protected areas are truly effective at conserving biodiversity remains an important question. Factors affecting the efficacy of biodiversity conservation in protected area are complex - human population density, policy enforcement, and local community attitudes towards conservation could all influence conservation outcomes. In this study, I measured how attitudes towards conservation and perception of law enforcement (based on 354 questionnaire surveys) in communities surrounding protected areas was associated with wildlife within the protected areas. I used motion-triggered camera traps (12,148 camera-trap days in total) and Bayesian hierarchical statistical models to estimate occupancy rates for four commonly hunted mammal species, as well as the species richness of medium- to large-sized mammals in six protected areas in Xishuangbanna, southern China, a diverse sub-tropical region with high hunting and land conversion pressures. I found that abundance of the large size species-wild boar (Sus scrofa) and small size Asian palm civet (Paradoxurus hermaphroditus), was positively correlated with park size. However, the villager-reported number of punishments the park meted out for law violations, and the villager-reported frequency of outreach by park staff to the local communities did not have significant effects on population size as well as richness of wildlife. Mammal diversity of mammal across parks was more correlated with villager-reported law enforcement effort than with outreach, even in parks surrounded by large human populations. My study highlighted the importance of reserve size, adequate habitat is the key of maintaining wildlife population in this area. My study provides insights that protected areas that have stricter enforcement as well as more frequent outreach activities could be more effective and our approach is applicable to assess effects of conservation actions on wildlife.

description: Information behaviour has emerged as an important aspect of human life; however, our knowledge and understanding of it is incomplete and underdeveloped scientifically. Our understanding of information behaviour and the sub-process information organizing behaviour is largely contemporary in focus. In this presentation Professor Spink discusses an evolutionary and developmental framework for information behaviour and information organizing from her recent book Information Behaviour: An Evolutionary Instinct (2010, Springer) by incorporating related findings, theories and models from evolutionary psychology, cognitive archaeology, cognitive neuroscience and developmental psychology.
 In her presentation, she argues that information behavior and information organizing are important instinctive socio-cognitive abilities for all humans that can only be fully understood with an evolutionary and developmental perspective.
 Professor Spink’s presentation addresses four important research questions. Firstly, what is the evolutionary, biological and developmental basis for information behaviour and information organizing behaviour? Secondly, what is the role of instinct versus environment in shaping information behaviour and information organizing behaviour? Thirdly, how have information behaviour and organizing capabilities evolved and developed over human species? Fourthly, when and how do information behaviour and in particular information organizing abilities emerge in young children? An evolutionary and developmental approach lays the foundation for a more holistic perspective on information behaviour and information organizing behaviour, and opens many new research directions.
The effects of video racing games on risk-taking in consideration of the game experience

description: In the present study, we attempted to investigate whether it is the game experience that underlies processes leading to increased risk-taking while playing video racing games (VRGs). The aim of the study was to examine the indirect effect of playing VRGs on risky driving behaviour through various dimensions of the game experience. Thus, we examined the subjective experience of participants playing various VRGs and questioned whether this influenced subsequent driving behaviour. The results of the present study show that aspects of the playing experience, in particular “flow” and “competence”, appear to be important in the regulation of risk appetite. It can be assumed that, rather than the mere playing of VRGs, the type of game experience during play is determinant for subsequent risk propensity while driving.
Corrosion behavior of reinforced concrete bridge decks under laboratory and field conditions
Creators: name: Al-Nawadi, Hasan
Publisher: name: No Publisher Supplied
Year: 2019

description: Reinforced concrete is one of the most efficient building materials widely used across the world, however, corrosion of its embedded steel reinforcement is the most aggressive rival to its durability. Corrosion becomes more aggressive in the presence of cracks, which makes the ingress of chloride ions from deicing salts into concrete bridge decks more critical, leading to an annual cost of about 8.3 billion for mitigation and rehabilitation of bridge decks in the United States of America.  The research consists of two components: laboratory testing and field monitoring. The laboratory testing is aimed at evaluating the effects of cracks and crack sealants in concrete specimens on the corrosion process using ASTM G109, and correlation of bridge deck service life and long-term predictions with field performance.  The laboratory-based experimental program includes the use of various small-scale specimens as well as deck slabs to study the effect of various parameters such as crack width and depth as well as the efficiency of the crack sealants.  Five types of steel reinforcement (Black, Duplex stainless, Galvanized, MMFX, and Epoxy-Coated), two types of concrete classes (class A and HPC), and two Sodium chloride concentrations (3% and 15%) were used. Additionally, four crack patterns, two different crack sealants, and two types of sensors (2000 silver-silver chloride electrode and multi element probes MEPs) were also used.  On the other hand, the field work used corrosion sensors for 20 years to maintain the structural health monitoring (SHM) and data collection of two existing bridges, GSP 84.1 and 159.7.After three years of exposure to diluted as well as severe sodium chloride solutions, laboratory results show that concrete specimens with Duplex Stainless and MMFX steel rebars had an excellent corrosion resistance in comparison with Epoxy-coated rebars.  Moreover, the crack depth has more influence than the crack width for all specimens. When the cracks are sealed using the T-70 MX crack sealant, it showed a remarkable efficiency in comparison with Seal Krete sealant.  Additionally, results from the field monitoring of the two bridge decks show that Galvanized Steel rebars underwent noticeable corrosion activity in comparison with the Stainless Steel deck.   Moreover, data collected from laboratory tests and field performance is used to validate results from simulation model to correlate service life predictions from accelerated laboratory-based tests.

description: Introduction: Biases in the measurement of COVID-19 burden and the uncertainty in estimation of the corresponding epidemiologic indexes are known and common phenomena in infectious diseases. Seeking causal relations between the vaccination or infection-gained immunity level and the infection dynamics could be misleading without understanding the socio-epidemiologic context such as the moderating and mediating role of healthcare access HCA (sensu lato). We investigated to what extent (HCA)-related supply/demand interfered with the registered data on COVID-19 in Poland. Material and Methods: We ran casual models with Bayesian optimisation criteria (with use of ‘mediation’ and ‘bnlearn’ R libraries) to explain the geographic variation of incidence/mortality in beginning of the 4th wave of COVID-19 (so-called “Delta” wave in Autumn 2021) on county – old NUTS-4 level. We took vaccination coverage and cumulative incidence up to the so-called 3rd wave as predictor variables and supply/demand HCA as moderating/mediating variables. Results: HCA (mainly demand) directly or through paths was shown to have the highest causal effect on incidence. We proved that hypothesis of mediation triangle between cumulative and current incidence by demand HCA has > 99% probability of being actually mediation triangle, as well as it is very strong (at least by order of magnitude higher that any other causal path) and stable (94% of occurrence by hill-climbing criterium). There is also not as strong, but also significant (95% of occurrence by hill-climbing criterium) moderating phenomenon of supply HCA on vaccination having protective effects deaths due to COVID-19. Conclusion: The most important finding is that spatial distribution of case notifications is mainly driven by the way people decide to use the healthcare system rather than epidemic processes. Moreover, death rates and the vaccination rates by regions have been significantly confounded by supply HCA, which is linked to the healthcare system capacities. We suggest that future epidemiological models must adopt demand HCA as a factor of so-called ‘dark figure’ of infections. Otherwise, spatial models may be more likely to overfit into people’s decisions on testing rather than to actual burden of disease. Moreover, the link between the reported case numbers and the true state of the epidemic can be spatio-temporally adjusted according to our proposition.

description: We present an algorithm for systematically reconstructing a solution of the (d+2)-dimensional vacuum Einstein equations from a (d+1)-dimensional fluid, extending the non-relativistic hydrodynamic expansion of Bredberg et al in arXiv:1101.2451 to arbitrary order. The fluid satisfies equations of motion which are the incompressible Navier-Stokes equations, corrected by specific higher derivative terms. The uniqueness and regularity of this solution is established to all orders and explicit results are given for the bulk metric and the stress tensor of the dual fluid through fifth order in the hydrodynamic expansion. We establish the validity of a relativistic hydrodynamic description for the dual fluid, which has the unusual property of having a vanishing equilibrium energy density. The gravitational results are used to identify transport coefficients of the dual fluid, which also obeys an interesting and exact constraint on its stress tensor. We propose novel Lagrangian models which realise key properties of the holographic fluid.

Impact of river dynamics on the genetic variation of Gypsophila repens (Caryophyllaceae): a comparison of heath forest and more dynamic gravel bank populations along an alpine river
Creators: name: Reisch, Christoph
name: Sattler, Julia
Publisher: name: Universität Regensburg
Year: 2020
Subjects: subject: 580 Pflanzen (Botanik)

description: Alpine rivers are, despite anthropogenic water flow regulation, still often highly dynamic ecosystems. Plant species occurring along these rivers are subject to ecological disturbance, mainly caused by seasonal flooding. Gypsophila repens typically grows at higher altitudes in the Alps, but also occurs at lower altitudes on gravel banks directly along the river and in heath forests at larger distances from the river. Populations on gravel banks are considered non‐permanent and it is assumed that new individuals originate from seed periodically washed down from higher altitudes. Populations in heath forests are, in contrast, permanent and not regularly provided with seeds from higher altitudes through flooding. If the genetic structure of this plant species is strongly affected by gene flow via seed dispersal, then higher levels of genetic diversity in populations but less differentiation among populations on gravel banks than in heath forests can be expected. In this study, we analysed genetic diversity within and differentiation among 15 populations of G. repens from gravel banks and heath forests along the alpine River Isar using amplified fragment length polymorphisms (AFLP). Genetic diversity was, as assumed, slightly higher in gravel bank than in heath forest populations, but genetic differentiation was, in contrast to our expectations, comparable among populations in both habitat types. Our study provides evidence for increased genetic diversity under conditions of higher ecological disturbance and increased seed dispersal on gravel banks. Similar levels of genetic differentiation among populations in both habitat types can be attributed to the species' long lifetime, a permanent soil seed bank and gene flow by pollinators among different habitats/locations.

description: Let $G$ be an arbitrary finite group. The McKay conjecture asserts that $G$ and the normaliser $N_G (P)$ of a Sylow $p$-subgroup $P$ in $G$ have the same number of characters of degree not divisible by $p$ (that is, of $p'$-degree). We propose a new refinement of the McKay conjecture, which suggests that one may choose a correspondence between the characters of $p'$-degree of $G$ and $N_G (P)$ to be compatible with induction and restriction in a certain sense. This refinement implies, in particular, a conjecture of Isaacs and Navarro. We also state a corresponding refinement of the Broué abelian defect group conjecture. We verify the proposed conjectures in several special cases.

description: We present a parameter-free Wilson-type lattice Dirac operator with an 81-point stencil for the covariant derivative and the Laplacian which attempts to minimize the breaking of rotational symmetry near the boundary of the Brillouin zone. The usefulness of this "Brillouin operator" in practical applications is explored by studying the scaling of pseudoscalar decay constants in quenched QCD, with rather good results in the physical charm region. We also investigate the suitability of this operator as a kernel to the overlap procedure. Here, the resulting overlap operator is found to be cheaper to construct and significantly better localized than the variety with the standard Wilson kernel.

description: The value of data models in general and information models in specific has been evaluated by many scientific papers. UML as one modelling notation has documented its value as a foundation for precise specifications. Analyzing implementation guides for data exchange, they rarely include or are based on information models but simple data sets, if at all, as simple technical representation thereof. This paper wants to argue in favor of information models as a basis for creating interoperability specifications using a quite simple example and to include – or at least reference – them when providing implementation guides. The reader is invited to transfer this example to even more complex scenarios.
Who's the 'write' girl? : a poetic inquiry

description: This dissertation closely examines my own experiences as a creative writing facilitator, program coordinator, poet, feminist, and confidante at a creative writing non-profit organization in Vancouver, B.C. Write It . Write It was created specifically to support young women between the ages of 13 and 19 who have been labeled as ‘at-risk.’ I ground the dissertation in Foucauldian theory and situate this work within the field of Girls’ Studies. I braid this critical feminist educational work with the generative area of poetic inquiry to explore the multiple and differing ways the young women who were enrolled in the program have been understood and how the labels of ‘at-risk,’ ‘troubled,’ and ‘in-crisis’ have shaped them. I explore through poetic inquiry my interpretation of how each of the young women in differing ways shaped their own identities and experiences. The original poems were grounded in the detailed journal entries I kept while I was involved in the program. Through poetry I endeavor to represent the various experiences, impressions, understandings, and a witnessing of the young women at Write It. Inquiring poetically enables the exploration of the complexity, contradictions, and poignancy of the program, the young women, and the multiple roles I occupied. We need to get rid of the ‘fixing’ and ‘reformation’ discourses of youth. What needs to be done is to work to advance creativity and self-awareness. The poetic explorations provide effective theoretical, practical, and pedagogical approaches for ‘at-risk’ young women and contributes to the expansive and the fields of Girls’ Studies and poetic inquiry research.

description: Considering climate change, recent political debates often focus on measures to reduce CO2 emissions. One key component is the reduction of emissions produced by motorized vehicles. Since the amount of emission directly correlates to the velocity of a vehicle via energy consumption factors, a general speed limit is often proposed. This article presents a methodology to combine openly available topology data of road networks from OpenStreetMap (OSM) with pay-per-use API traffic data from TomTom to evaluate such measures transparently by analyzing historical real-world circumstances. From our exemplary case study of the German motorway network, we derive that most parts of the motorway network on average do not reach their maximum allowed speed throughout the day due to traffic, construction sites and general road utilization by network participants. Nonetheless our findings prove that the introduction of a speed limit of 120 km per hour on the German autobahn would restrict 50.74% of network flow kilometers for a CO2 reduction of 7.43% compared to the unrestricted state.

description: In this work, machine learning (ML) modeling is proposed for the detection and classification of global positioning system (GPS) spoofing in unmanned aerial vehicles (UAVs). Three testing scenarios are implemented in an outdoor yet controlled setup to investigate static and dynamic attacks. In these scenarios, authentic sets of GPS signal features are collected, followed by other sets obtained while the UAV is under spoofing attacks launched with a software-defined radio (SDR) transceiver module. All sets are standardized, analyzed for correlation, and reduced according to feature importance prior to their exploitation in training, validating, and testing different multiclass ML classifiers. Two schemes for the dataset are proposed, location-dependent and location-independent datasets. The location-dependent dataset keeps the location specific features which are latitude, longitude, and altitude. On the other hand, the location-independent dataset excludes these features. The resulting performance evaluation of these classifiers shows a detection rate (DR), misdetection rate (MDR), and false alarm rate (FAR) better than 92%, 13%, and 4%, respectively, together with a sub-millisecond detection time. Hence, the proposed modeling facilitates accurate real-time GPS spoofing detection and classification for UAV applications.
 Then, a three-class ML model is implemented on a UAV with a Raspberry Pi processor for classifying the two GPS spoofing attacks (i.e., static, dynamic) in real-time. First, several models are developed and tested utilizing the prepared dataset. Models evaluation is carried out using the DR, F-score, FAR, and MDR, which all showed an acceptable performance. Then, the optimum model is loaded to the onboard processor and tested for real-time detection and classification. Location-dependent applications, such as fixed-route public transportation, are expected to benefit from the methodology presented herein as the longitude, latitude, and altitude features are characterized in the implemented model.

description: We introduce generalized quantifiers, as defined in Tarskian semantics by Mostowski and Lindström, in logics whose semantics is based on teams instead of assignments, e.g., IF-logic and Dependence logic. Both the monotone and the non-monotone case is considered. It is argued that to handle quantifier scope dependencies of generalized quantifiers in a satisfying way the dependence atom in Dependence logic is not well suited and that the multivalued dependence atom is a better choice. This atom is in fact definably equivalent to the \emph{independence atom} recently introduced by Väänänen and Grädel.

Power to the people : thinking (and rethinking) energy poverty in British Columbia, Canada
Creators: name: Rezaei, Maryam
Publisher: name: University of British Columbia
Year: 2017

description: Energy poverty, or the experience of struggling to meet one’s energy needs, is increasingly the subject of attention in Canada — though no established definition for it exists and the definitions that are used often obscure its connections with the systemic processes that create it. In this dissertation, I situate energy poverty as a justice issue and operationalize various understandings of justice (distributive, procedural, recognition-based and restorative) to discuss how energy poverty may be conceptualized in the settler- colonial context of Canada, and, indeed, how different conceptualization reveal different processes of its creation, as well as different approaches to addressing it. Based on empirical work with two First Nations communities in British Columbia (Musqueam and Tsay Keh Dene), I outline the unfolding of energy poverty in BC amidst a constructed narrative of energy plenty, which aims to expand the reach of the extractive energy industry in the province. In doing so, I link specific energy planning processes that create precarious energy access, with mundane details of how energy poverty manifests itself in household practices that use energy. This linking of the experience of those who experience energy poverty and energy planning processes that create it reveals not only how industrial energy demand in BC is privileged over residential energy use broadly, but also how the energy demands of off-grid indigenous communities such as Tsay Keh are deemed ‘artificial and illegitimate in the community energy planning process. This ethnographic work (including surveys, interviews, energy mapping exercises and energy ana- lytics) is complemented with a statistical analysis of data from Statistics Canadas Survey of Household Spending. This analysis highlights patterns in energy poverty across Canada and demonstrates a gap between the experience of energy poverty and the design and targeting of the residential energy retrofit programs that aim to address it. I conclude by making a series of recommendations for those who fight for energy justice, including the development of community-based energy programming (e.g. deep retrofits and community renewable projects) and broadening the scope of energy poverty alleviation programs from a focus on low-income households to include lower-middle class households as well.

description: Multidisciplinary and highly dynamic pHealth ecosystems according to the 5P Medicine paradigm require careful consideration of systems integration and interoperability within the domains knowledge space. The paper addresses the different aspects or levels of knowledge representation (KR) and management (KM) from cognitive theories (theories of knowledge) and modeling processes through notation up to processing, tooling and implementation. Thereby, it discusses language and grammar challenges and constraints, but also development process aspects and solutions, so demonstrating the limitation of data level considerations. Finally, it presents the ISO 23903 Interoperability and Integration Reference Architecture to solve the addressed problems and to correctly deploy existing standards and work products at any representational level including data models as well as data model integration and interoperability.

description: Studying two-dimensional field theories in the presence of defect lines naturally gives rise to monoidal categories: their objects are the different (topological) defect conditions, their morphisms are junction fields, and their tensor product describes the fusion of defects. These categories should be equipped with a duality operation corresponding to reversing the orientation of the defect line, providing a rigid and pivotal structure. We make this structure explicit in topological Landau-Ginzburg models with potential x^d, where defects are described by matrix factorisations of x^d-y^d. The duality allows to compute an action of defects on bulk fields, which we compare to the corresponding N=2 conformal field theories. We find that the two actions differ by phases.

description: Fast Radio Bursts (FRBs) are highly energetic millisecond-duration astrophysical phenomena typically categorized as repeaters or non-repeaters. However, observational limitations may result in misclassifications, potentially leading to a higher proportion of repeaters than currently identified. In this study, we leverage unsupervised machine learning techniques to classify FRBs using data from the CHIME/FRB catalogs, including both the first catalog and a recent repeater catalog. By employing Uniform Manifold Approximation and Projection for dimensionality reduction and clustering algorithms (k-means and Hierarchical Density-Based Spatial Clustering of Applications with Noise), we successfully segregate repeaters and non-repeaters into distinct clusters, identifying over 100 potential repeater candidates. Our analysis reveals several empirical relations within the clusters, including the ${\rm log \,}Δt_{sc}-{\rm log \,}Δt_{rw}$, ${\rm log \,}Δt_{sc}-{\rm log \,}T_B$, and $r - γ$ correlations, where ${Δt_{sc}, Δt_{rw}, T_B, r, γ}$ represent scattering time, rest-frame width, brightness temperature, spectral running, and spectral index, respectively. The Chow test results reveal that while some repeaters and non-repeaters share similar empirical relationships, the overall distinctions between the two groups remain significant, reinforcing the classification of FRBs into repeaters and non-repeaters. These findings provide new insights into the physical properties and emission mechanisms of FRBs. This study demonstrates the effectiveness of unsupervised learning in classifying FRBs and identifying potential repeaters, paving the way for more precise investigations into their origins and applications in cosmology. Future improvements in observational data and machine learning methodologies are expected to further enhance our understanding of FRBs.

description: Each Morita--Mumford--Miller (MMM) class e_n assigns to each genus g >= 2 surface bundle S_g -> E^{2n+2} -> M^{2n} an integer e_n^#(E -> M) := in Z. We prove that when n is odd the number e_n^#(E -> M) depends only on the diffeomorphism type of E, not on g, M, or the map E -> M. More generally, we prove that e_n^#(E -> M) depends only on the cobordism class of E. Recent work of Hatcher implies that this stronger statement is false when n is even. If E -> M is a holomorphic fibering of complex manifolds, we show that for every n the number e_n^#(E -> M) only depends on the complex cobordism type of E. We give a general procedure to construct manifolds fibering as surface bundles in multiple ways, providing infinitely many examples to which our theorems apply. As an application of our results we give a new proof of the rational case of a recent theorem of Giansiracusa--Tillmann that the odd MMM classes e_{2i-1} vanish for any surface bundle which bounds a handlebody bundle. We show how the MMM classes can be seen as obstructions to low-genus fiberings. Finally, we discuss a number of open questions that arise from this work.

description: Today’s digital information systems and applications collect every day a huge amount of personal health information (PHI) from sensor and surveillance systems, and every time we use personal computers or mobile phones. Collected data is processed in clouds, platforms and ecosystems by digital algorithms and machine learning. Pervasive technology, insufficient and ineffective privacy legislation, strong ICT industry and low political will to protect data subject’s privacy have together made it almost impossible for a user to know what PHI is collected, how it is used and to whom it is disclosed. Service providers’ and organizations’ privacy policy documents are cumbersome and they do not guarantee that PHI is not misused. Instead, service users are expected to blindly trust in privacy promises made. In spite of that, majority of individuals are concerned of their privacy, and governments’ assurance that they meet the responsibility to protect citizens in real life privacy is actually dead. Because PHI is probably the most sensitive data we have, and the authors claim it cannot be a commodity or public good, they have studied novel privacy approaches to find a way out from the current unsatisfactory situation. Based on findings got, the authors have developed a promising solution for privacy-enabled use of PHI. It is a combination of the concept of information fiduciary duty, Privacy as Trust approach, and privacy by smart contract. This approach shifts the onus of privacy protection onto data collectors and service providers. A specific information fiduciary duty law is needed to harmonize privacy requirements and force the acceptance of proposed solutions. Furthermore, the authors have studied strengths and weaknesses of existing or emerging solutions.

description: We consider the production of the Standard Model Higgs boson through the gluon fusion mechanism in hadron collisions. We present the next-to-next-to-leading order (NNLO) QCD result of the hard-collinear coefficient function for the all-order resummation of logarithmically-enhanced contributions at small transverse momentum. The coefficient function controls NNLO contributions in resummed calculations at full next-to-next-to-leading logarithmic accuracy. The same coefficient function is used in applications of the subtraction method to perform fully-exclusive perturbative calculations up to NNLO.
