description: We report on the dynamics of a model frictional system submitted to minute external perturbations. The system consists of a chain of sliders connected through elastic springs that rest on an incline. By introducing cyclic expansions and contractions of the springs we observe a reptation of the chain. We account for the average reptation velocity theoretically. The velocity of small systems exhibits a series of plateaus as a function of the incline angle. Due to elastic e ects, there exists a critical amplitude below which the reptation is expected to cease. However, rather than a full stop of the creep, we observe in numerical simulations a transition between a continuous-creep and an irregular-creep regime when the critical amplitude is approached. The latter transition is reminiscent of the transition between the continuous and the irregular compaction of granular matter submitted to periodic temperature changes.
The Complexities of Healing in Secure Group Messaging: Why Cross-Group Effects Matter

Publisher: name: CISPA
Year: 2023

description: Modern secure messaging protocols can offer strong security guarantees such as Post-Compromise Security (PCS) [18], which enables participants to heal after compromise. The core PCS mechanism in protocols like Signal [34] is designed for pairwise communication, making it inefficient for large groups, while recently proposed designs for secure group mes- saging, ART [19], IETF’s MLS Draft-11 [7]/TreeKEM [11], use group keys derived from tree structures to efficiently pro- vide PCS to large groups. Until now, research on PCS designs only considered healing behaviour within a single group. In this work we provide the first analysis of the healing behaviour when a user participates in multiple groups. Sur- prisingly, our analysis reveals that the currently proposed pro- tocols based on group keys, such as ART and TreeKEM/MLS Draft-11, provide significantly weaker PCS guarantees than group protocols based on pairwise PCS channels. In fact, we show that if new users can be created dynamically, ART, TreeKEM, and MLS Draft-11 never fully heal authentication. We map the design space of healing mechanisms, analyz- ing security and overhead of possible solutions. This leads us to a promising solution based on (i) global updates that affect all current and future groups, and (ii) post-compromise secure signatures. Our solution allows group messaging pro- tocols such ART and MLS to achieve substantially stronger PCS guarantees. We provide a security definition for post- compromise secure signatures and an instantiation.
Partitioning the flags of PG(2,q) into strong representative systems
Creators: name: Mengyán, Csaba
Publisher: name: Faculty of Science, University of Calgary
Year: 2008

description: In this paper we show

a natural extension of the idea used by Ill\'es, Sz\H{o}nyi and Wettl

\cite{swi}  which proved that the flags of 

${\rm PG} (2,q)$ can be partitioned into 

$(q-1)\sqrt q+3q$ strong representative systems for $q$ an odd square.

 From a generalization

of the Buekenhout construction of unitals \cite{kozoscikk} their idea

can be applied for any non-prime $q^h$ to yield

that $q^{2h-1}+2q^h$ strong representative systems partition

the flags of ${\rm PG} (2,q^{h})$. 

In this way we

also give a solution to a question of Gy\'arf\'as \cite{FSGT} about 

the strong chromatic index of the bipartite graph corresponding to 

${\rm PG} (2,q)$, for $q$ non-prime.

Phase separation in fluids exposed to spatially periodic external fields

description: We consider the liquid-vapor type phase transition for fluids confined within spatially periodic external fields. For a fluid in d=3 dimensions, the periodic field induces an additional phase, characterized by large density modulations along the field direction. At the triple point, all three phases (modulated, vapor, and liquid) coexist. At temperatures slightly above the triple point and for low (high) values of the chemical potential, two-phase coexistence between the modulated phase and the vapor (liquid) is observed. We study this phenomenon using computer simulations and mean-field theory for the Ising model. The theory shows that, in order for the modulated phase to arise, the field wavelength must exceed a threshold value. We also find an extremely low tension of the interface between the modulated phase and the vapor/liquid phases. The tension is of the order 10^{-4} kB T per squared lattice spacing, where kB is the Boltzmann constant, and T the temperature. In order to detect such low tensions, a new simulation method is proposed. We also consider the case of d=2 dimensions. The modulated phase then does not survive, leading to a radically different phase diagram.

Distortional Lateral Torsional Buckling of Doubly Symmetric Wide Flange Beams

description: Distortional lateral-torsional buckling theories assume that the flanges remain undistorted, while the web is free to distort as a thin plate. Most theories adopt a cubic polynomial distribution along the web height to relate the lateral displacement of the web to the displacements and angles of twist both flanges. The present study develops a family of finite element solutions for the distortional buckling of wide flange beams in which the flanges are assumed to remain undistorted. In contrast to past theories, the lateral displacement distribution along the web height is characterized by superposing (a) two linear modes intended to capture the classical non-distortional lateral-torsional behavior and (b) any number of user-specified Fourier terms intended to capture additional web distortion. In the longitudinal direction, all displacement fields characterizing the lateral displacements are taken to follow a cubic distribution. The first contribution of the thesis develops a finite element formulation that is able to replicate the classical non-distortional lateral torsional buckling solutions when the distortional modes are suppressed while enabling more accurate predictions for distortional lateral torsional buckling compared to those solutions based on the conventional cubic interpolation of the lateral displacement. The formulation is used to conduct an extensive parametric study to quantify the reduction in critical moments due to web distortion relative to the classical non-distortional predictions in the case of simply-supported beams, cantilevers, and beams with an overhang. The solution is then used to generate interaction curves for beams with an overhang subjected to various proportions of uniformly distributed and point loads. The second contribution of the thesis adds two additional features to the formulation (a) to capture the destabilizing effect due to the load height relative to the shear center and (b) a module that incorporates any number of user-defined multi-point kinematic constraints. The additional features are employed to investigate the effect of load height, bracing height, and combined effects thereof in practical design problems. A distortional indicator is then introduced to characterize the distribution of web distortion along the beam span as the beam undergoes distortional lateral buckling. A systematic design optimization technique is then devised to identify the location(s) along the span at which the addition of transverse stiffeners would maximize the critical moment capacity.
Origin of the Cosmic Ray Spectral Hardening

description: Recent data from ATIC, CREAM and PAMELA indicate that the cosmic ray energy spectra of protons and nuclei exhibit a remarkable hardening at energies above 100 GeV per nucleon. We propose that the hardening is an interstellar propagation effect that originates from a spatial change of the cosmic-ray transport properties in different regions of the Galaxy. The key hypothesis is that the diffusion coefficient is not separable into energy and space variables as usually assumed. Under this scenario, we can reproduce the observational data well. Our model has several implications for the cosmic-ray acceleration/propagation physics and can be tested by ongoing experiments such as the Alpha Magnetic Spectrometer or Fermi/LAT.

description: DDoS attacks threaten Internet security and stability, with attacks reaching the Tbps range. A popular approach involves DNS-based reflection and amplification, a type of attack in which a domain name, known to return a large answer, is queried using spoofed requests. Do the chosen names offer the largest amplification, however, or have we yet to see the full amplification potential? And while operational countermeasures are proposed, chiefly limiting responses to ‘ANY’ queries, up to what point will these countermeasures be effective? In this paper we make three main contributions. First, we propose and validate a scalable method to estimate the amplification potential of a domain name, based on the expected ANY response size. Second, we create estimates for hundreds of millions of domain names and rank them by their amplification potential. By comparing the overall ranking to the set of domains observed in actual attacks in honeypot data, we show whether attackers are using the most-potent domains for their attacks, or if we may expect larger attacks in the future. Finally, we evaluate the effectiveness of blocking ANY queries, as proposed by the IETF, to limit DNS-based DDoS attacks, by estimating the decrease in attack volume when switching from ANY to other query types. Our results show that by blocking ANY, the response size of domains observed in attacks can be reduced by 57%, and the size of most-potent domains decreases by 69%. However, we also show that dropping ANY is not an absolute solution to DNS-based DDoS, as a small but potent portion of domains remain leading to an expected response size of over 2,048 bytes to queries other than ANY.

description: In this document we will review the current status of reactor neutrino oscillation experiments and present their physics potentials for measuring the $θ_{13}$ neutrino mixing angle. The neutrino mixing angle $θ_{13}$ is currently a high-priority topic in the field of neutrino physics. There are currently three different reactor neutrino experiments, \textsc{Double Chooz}, \textsc{Daya Bay} and \textsc{Reno} and a few accelerator neutrino experiments searching for neutrino oscillations induced by this angle. A description of the reactor experiments searching for a non-zero value of $θ_{13}$ is given, along with a discussion of the sensitivities that these experiments can reach in the near future.

Arcs in Desarguesian nets

Year: 2008

description: A trivial upper bound on the size k of an arc in an r-net is $k \leq r + 1$. It has been known for about 20 years that if the r-net is Desarguesian and has odd order, then the case $k = r + 1$ cannot occur, and $k \geq r - 1$ implies that the arc is contained in a conic. In this paper, we show that actually the same must hold provided that the difference $r - k$ does not exceed $\sqrt{k/18}$. Moreover, it is proved that the same assumption ensures that the arc can be extended to an oval of the net.

Graph Similarity Description: How Are These Graphs Similar?

description: How do social networks differ across platforms? How do information networks change over time? Answering questions like these requires us to compare two or more graphs. This task is commonly treated as a measurement problem, but numerical answers give limited insight. Here, we argue that if the goal is to gain understanding, we should treat graph similarity assessment as a description problem instead. We formalize this problem as a model selection task using the Minimum Description Length principle, capturing the similarity of the input graphs in a common model and the differences between them in transformations to individual models. To discover good models, we propose Momo, which breaks the problem into two parts and introduces efficient algorithms for each. Through an extensive set of experiments on a wide range of synthetic and real-world graphs, we confirm that Momo works well in practice
De kvindefokuserede dramedieserier

description: Mads Møller Andersen’s article discusses the representation of female roles in TV dramedy shows by exploring previous dramedies such as the glamorous Sex And The City and comparing them to the more unconventional dramedies of today: HBO’s Girls and Netflix’s Orange Is The New Black. The central thesis of the article is that there has been a certain trend during the latest two decades within the dramedy genre where a group of dramedies have focused on female protagonists, female issues, and a female audience. But this trend in the dramedy genre also stands as a testament to a development in female TV characters because recent dramedies seem to dismiss the conventional values of the previous dramedy shows. Girls and Orange Is The New Black choose to push the boundaries and exemplify how women on TV can be chubby, self-destructive and even dangerous.

Simultaneous analysis of a sequence of paired ecological tables: A comparison of several methods
Creators: name: Thioulouse, Jean
Publisher: name: arXiv
Year: 2012
Subjects: subject: Applications (stat.AP)
subject: FOS: Computer and information sciences

description: A pair of ecological tables is made of one table containing environmental variables (in columns) and another table containing species data (in columns). The rows of these two tables are identical and correspond to the sites where environmental variables and species data have been measured. Such data are used to analyze the relationships between species and their environment. If sampling is repeated over time for both tables, one obtains a sequence of pairs of ecological tables. Analyzing this type of data is a way to assess changes in species-environment relationships, which can be important for conservation Ecology or for global change studies. We present a new data analysis method adapted to the study of this type of data, and we compare it with two other methods on the same data set. All three methods are implemented in the ade4 package for the R environment.

Global Gender

description: In Global Woman (2004) Barbara Ehrenreich has problematized the focus in the 1960s and 70s feminist movement on Western gender issues and changed the emphasis on white, middle-class men and women to their others in terms of race, class and topography. Michel Foucault has also, with his work on heterotopoi, uncovered the hidden aspects of modernity, the residual spaces far from centers of power, whose inhabitants have recently found western publishers and audiences and changed Western discussions of gender already begun. Inside and outside China, writers have offered glimpses of rural Chinese heterotopias, and of gendered experiences both in their native China and in the United States. This paper, “Global Gender”, focuses on gender issues in recent Chinese and Chinese American fiction and engages with Foucault and other theorists to uncover hidden network of relations, the interdependencies between men and women with and without power that now await attention, or, if global inequalities turn into violence, explosion.

description: We model the chameleon effect on cosmological statistics for the modified gravity f(R) model of cosmic acceleration. The chameleon effect, required to make the model compatible with local tests of gravity, reduces force enhancement as a function of the depth of the gravitational potential wells of collapsed structure and so is readily incorporated into a halo model by including parameters for the chameleon mass threshold and rapidity of transition. We show that the abundance of halos around the chameleon mass threshold are enhanced by both the merging from below and the lack of merging to larger masses. This property also controls the power spectrum in the nonlinear regime and we provide a description of the transition to the linear regime that is valid for a wide range of f(R) models.

Estimation of surface-free data by curvelet-domain matched filtering and sparse inversion
Creators: name: AlMatar, Mufeed H.
Publisher: name: University of British Columbia
Year: 2011

description: A recent robust multiple-elimination technique, based on the underlying principle that relates primary impulse response to total upgoing wavefield, tries to change the paradigm that sees surface-related multiples as noise that needs to be removed from the data prior to imaging. This technique, estimation of primaries by sparse inversion (EPSI), (van Groenestijn and Verschuur, 2009; Lin and Herrmann, 2009), proposes an inversion procedure during which the source function and surface-free impulse response are directly calculated from the upgoing wavefield using an alternating optimization procedure. EPSI hinges on a delicate interplay between surface-related multiples and pri- maries. Finite aperture and other imperfections may violate this relationship. In this thesis, we investigate how to make EPSI more robust by incorporating curvelet- domain matching in its formulation. Compared to surface-related multiple removal (SRME), where curvelet-domain matching was used successfully, incorporating this step has the additional advantage that matches multiples to multiples rather than predicated multiples to total data as in SRME.

description: A new method for the nonperturbative solution of quantum field theories is described. The method adapts the exponential-operator technique of the standard many-body coupled-cluster method to the Fock-space eigenvalue problem for light-front Hamiltonians. This leads to an effective eigenvalue problem in the valence Fock sector and a set of nonlinear integral equations for the functions that define the exponential operator. The approach avoids at least some of the difficulties associated with the Fock-space truncation usually used.

description: The addition of Mary Morstan to Series 3 of the BBC’s Sherlock is analysed through the application of Eve Sedgwick’s theory of homosociality as well as performativity theory to shed light on how a female character can be used not to only police a male-male relationship, but also create a safe space for them to express sentiment. The analysis of Mary’s role in BBC’s Sherlock suggests that she is mainly used to ensure that the performance of sexuality in BBC Sherlock was mainly heterosexual, although the performative level of the program leans towards a homosexual reading in regards to John and Sherlock. The main thesis of this article is that female characters are used to police male-male relationships, ensuring that heterosexuality is the true sexuality of the main characters; though homosocial and homosexual tendencies might be expressed.

description: Optical coupling of an ensemble of silicon-vacancy (SiV) centers to single-crystal diamond microdisk cavities is demonstrated. The cavities are fabricated from a single-crystal diamond membrane generated by ion implantation and, electrochemical liftoff followed by homo-epitaxial overgrowth. Whispering gallery modes which spectrally overlap with the zero-phonon line (ZPL) of the SiV centers and exhibit quality factors ~2200 are measured. Lifetime reduction from 1.8 ns to 1.48 ns is observed from SiV centers in the cavity compared to those in the membrane outside the cavity. These results are pivotal in developing diamond integrated photonics networks.
Self-management activities in type 2 diabetes: a structural equation modeling analysis
Creators: name: Harvey, Natasha R.
Publisher: name: University of Calgary
Year: 2006

description: Bibliography: p. 142-165
description: Background: A plethora of psychosocial predictors of Type 2 diabetes self-management adherence have been identified, yet these variables generally fail to account for more than about 25% of the variance in measures of diabetes adherence. The predominance of the Type 2 diabetes adherence literature represents behaviour change (intrapersonal) and social support (interpersonal) models. Few studies have examined the roles of empirically supported diabetes adherence predictors within a social-ecological model framework. Purpose: To use structural equation modeling to increase our understanding of the associations among social-ecological support resources, perceived locus of control of diabetes, negative affect (anxiety, depression, and alexithymia), and Type 2 diabetes self-care activities. Methods: This cross-sectional study utilized a convenience sample of 235 participants (54% male, 46% female) aged 25 to 87 (Mage= 56, SD = 11) with Type 2 diabetes from Calgary's Regional Diabetes Education Centre. Self-report measures were distributed for home completion and returned by post. Primary measures included (1) Chronic Illness Resources Survey, (2) Perceived Control of Diabetes Scales, (3) Twenty-Item Toronto Alexithymia Que tionnaire, (4) Well-Being Questionnaire anxiety and depression subscales, and (5) ummary of Diabetes Self-Care Activities Questionnaire, with an appended foot-care measure. Structural equation modeling was used to assess measurement and structural models. Results: Social-ecological support resources emerged as the sole direct predictor of diabetes self-care activity, accounting for 45% of the variance in diabetes self-care activity. Intraindividual variables ( decreased emotional well-being, perceived personal and situational control) had indirect effects on diabetes self-care activity primarily through their direct influence on social- 111 ecological support resources. Conclusions: The present study suggests that previous emphasis on the direct influence of intrapersonal variables measured in this study is likely an oversimplification of the complex interaction among variables influencing Type 2 diabetes self-care activities. Further, the results support a strong positive direct influence of utilization of social-ecological support resources on diabetes self-care activity, while the measured intrapersonal variables had only a very modest indirect relationship with diabetes self-care activity. Results point to the importance of considering social-ecological models of Type 2 diabetes adherence and ensuring sufficient availability and personal utilization of social-ecological support resources in clinical practice.
Differentiable Pattern Set Mining

Year: 2023

description: Pattern set mining has been successful in discovering small sets of highly informative and useful patterns from data. To find good models, existing methods heuristically explore the twice-exponential search space over all possible pattern sets in a combinatorial way, by which they are limited to data over at most hundreds of features, as well as likely to get stuck in local minima. Here, we propose a gradient based optimization approach that allows us to efficiently discover high-quality pattern sets from data of millions of rows and hundreds of thousands of features. In particular, we propose a novel type of neural autoencoder called BinaPs, using binary activations and binarizing weights in each forward pass, which are directly interpretable as conjunctive patterns. For training, optimizing a data-sparsity aware reconstruction loss, continuous versions of the weights are learned in small, noisy steps. Hence, this formulation of our problem provides a link between the discrete search space and continuous optimization, thus allowing for a gradient based strategy to discover sets of high-quality and noise-robust patterns. Through extensive experiments on both synthetic and real world data, we show that BinaPs discovers high quality and noise robust patterns, and unique among all competitors, easily scales to real supermarket transaction and biological variant call data.

description: This piece aims to rescue Camille Paglia from waves of unsympathetic critics. The article asks what it is that she actually stands for. Employing the religious metaphors of “fallen” and “restored”, as well as the idea of “sacraments”, it argues that what is uppermost in the work of Paglia is a concern with a fallen state connected to sex and gender alignment (disempowering for both men and women) and a risen state in which self-fulfilment is effected by transgenderism. For Paglia, Graham argues, the social purpose of literature is to help individuals understand their own transgender destiny: writers provide models for that “migration”.

Representations of Intercourse in American Literature

Publisher: name: Akademisk kvarter | Academic Quarter
Year: 2013

description: This article investigates representations of sexual intercourse in American literature expressed via the use of fuck as a transitive verb. Its goal is to identify possible trends in the differentiation between men and women’s roles and power relations in such literary representations. Drawing on theoretical notions from cognitive poetics, the present article assumes that literary representations of intercourse reflect and replicate in readers cultural-cognitive models of intercourse and the roles of, and power relations between, men and women therein. The analysis presented here is quantitative and falls under the rubric of corpus stylistics, and it is based on data from the FICTION component of the Corpus of Historical American English. The analysis measures the preference of male or female passive participants in propositional scenarios denoted by transitive fuck, thus allowing for the identification of large-scale patterns in sexual objectification of men or women in American literature.

description: We introduce the largest connected subgraph game played on an undirected graph G. Each round, Alice colours an uncoloured vertex of G red, and then, Bob colours one blue. Once every vertex is coloured, Alice (Bob, resp.) wins if there is a red (blue, resp.) connected subgraph whose order is greater than that of any blue (red, resp.) connected subgraph. If neither player wins, it is a draw. We prove that Alice can ensure Bob never wins, and define a class of graphs (reflection graphs) in which the game is a draw. We show that the game is PSPACE-complete in bipartite graphs of diameter 5, and that recognising reflection graphs is GI-hard. We prove that the game is a draw in paths if and only if the path has even order or at least 11 vertices, and that Alice wins in cycles if and only if the cycle is of odd order. We also give an algorithm computing the outcome of the game in cographs in linear time.

description: A 2012 photo spread in a life-style men’s magazine, featuring young women clad in sexualized pastiches of school uniforms, was used by a Copenhagen University Professor of Philosophy to create what he thought of as light-hearted publicity for his Logics course that semester. This article analyses the images of the photo spread (contextualizing them with insights from humour theory), their reception in the philosophy community and the public at large, and discusses the implications of the ensuing chain of events in a gender debate perspective.

description: We describe how continuous-variable abelian anyons, created on the surface of a continuous-variable analogue of Kitaev's lattice model can be utilized for quantum computation. In particular, we derive protocols for the implementation of quantum gates using topological operations. We find that the topological operations alone are insufficient for universal quantum computation which leads us to study additional non-topological operations such as offline squeezing and single-mode measurements. It is shown that these in conjunction with a non-Gaussian element allow for universal quantum computation using continuous-variable abelian anyons.

description: In this work we experimentally implement a deterministic transfer of a generic qubit initially encoded in the orbital angular momentum of a single photon to its polarization. Such transfer of quantum information, completely reversible, has been implemented adopting a electrically tunable q-plate device and a Sagnac interferomenter with a Dove's prism. The adopted scheme exhibits a high fidelity and low losses.

Feasibility and sensitivity analysis of integrating mining and mineral carbonation : a case study of the Turnagain nickel project
Creators: name: Hindle, Sarah Robin
Publisher: name: University of British Columbia
Year: 2011

description: Proposed carbon reduction measures such as cap-and-trade appear poised to have a significant impact on the financial feasibility of mining operations as point-source emitters of carbon dioxide (CO₂). It is therefore necessary to proactively assess the ways in which these effects may be mitigated. Carbon sequestration through mineral carbonation is well suited for integration into mining operations of suitable geology for its ability to make use of waste rock to trap and store CO₂ and offset carbon emissions. The Turnagain Nickel site, a low-grade high-tonnage Ni-sulphide deposit located in Northern BC, contains an abundance of Mg-silicate minerals in its waste rock that have significant potential for use in mineral carbonation. This has the potential to produce an additional revenue stream through the generation and sale of carbon credits in the presence of a mandatory cap-and-trade scheme in North America. Results of financial modeling have yielded a net present value (NPV) at an 8% discount rate of $131.5 million for the integration of mineral carbonation into proposed mining operations at Turnagain, suggesting that the project may be viable from a financial standpoint. Sensitivity analysis has also demonstrated that the parameter with the greatest influence on project NPV is the CO₂ avoidance ratio. This ratio, which takes into consideration the amount of CO₂ released in the mineral carbonation process to determine the net amount of CO₂ avoided, is critical in order to maximize the amount of carbon credits available for sale in a cap-and-trade environment.
What's in the Box? Exploring the Inner Life of Neural Networks with Robust Rules
Creators: name: Fischer, Jonas

Publisher: name: CISPA
Year: 2023

description: We propose a novel method for exploring how neurons within neural networks interact. In particular, we consider activation values of a network for given data, and propose to mine noise-robust rules of the form X {\rightarrow} Y , where X and Y are sets of neurons in different layers. We identify the best set of rules by the Minimum Description Length Principle as the rules that together are most descriptive of the activation data. To learn good rule sets in practice, we propose the unsupervised ExplaiNN algorithm. Extensive evaluation shows that the patterns it discovers give clear insight in how networks perceive the world: they identify shared, respectively class-specific traits, compositionality within the network, as well as locality in convolutional layers. Moreover, these patterns are not only easily interpretable, but also supercharge prototyping as they identify which groups of neurons to consider in unison.
Dissipative hydrodynamics coupled to chiral fields

description: Using second--order dissipative hydrodynamics coupled self-consistently to the linear $σ$ model we study the 2+1 dimensional evolution of the fireball created in Au+Au relativistic collisions. We analyze the influence of the dynamics of the chiral fields on the charged-hadron elliptic flow $v_2$ and on the ratio $v_4/(v_2)^2$ for a temperature-independent as well as for a temperature-dependent viscosity-to-entropy ratio $η/s$ calculated from the linearized Boltzmann equation in the relaxation time approximation. We find that $v_2$ is not very sensitive to the coupling of chiral sources to the hydrodynamic evolution, but the temperature dependence of $η/s$ plays a much bigger role on this observable. On the other hand, the ratio $v_4/(v_2)^2$ turns out to be much more sensitive than $v_2$ to both the coupling of the chiral sources and the temperature dependence of $η/s$.

Non-perturbative unitarity constraints on the ratio of shear viscosity to entropy density in UV complete theories with a gravity dual

description: We reconsider, from a novel perspective, how unitarity constrains the corrections to the ratio of shear viscosity η to entropy density s. We start with higher-derivative extensions of Einstein gravity in asymptotically anti-de Sitter spacetimes. It is assumed that these theories are derived from string theory and thus have a unitary UV completion that is dual to a unitary, UV-complete boundary gauge theory. We then propose that the gravitational perturbations about a solution of the UV complete theory are described by an effective theory whose linearized equations of motion have at most two time derivatives. Our proposal leads to a concrete prescription for the calculation of η/s for theories of gravity with arbitrary higher-derivative corrections. The resulting ratio can take on values above or below 1/4π and is consistent with all the previous calculations, even though our reasoning is substantially different. For the purpose of calculating η/s, our proposal also leads to only two possible candidates for the effective two-derivative theory: Einstein and Gauss-Bonnet gravity. The distinction between the two is that Einstein gravity satisfies the equivalence principle, and so its graviton correlation functions are polarization independent, whereas the Gauss-Bonnet theory has polarization-dependent correlation functions. We discuss the graviton three-point functions in this context and explain how these can provide additional information on the value of η/s.

X-Ray Absorption Analysis of NGC3516: Appearance of Fast Components with Increased Source Flux

description: By analyzing the X-ray spectra of NGC 3516 from 2001 and 2006 obtained with the HETGS spectrometer on board the Chandra observatory, we find that the kinematic structure of the outflow can be well represented by four outflow components intrinsic to NGC 3516. The outflow velocities of the different components are 350 +-100 km s-1, 1500 +-150 km s-1, 2600 +-200 km s-1 and 4000 +-400 km s-1 for components 1, 2, 3 and 4, respectively. A local component at z = 0 could be confused with intrinsic component 3. Components 1 and 2 have a broad range of ionization manifested by absorption from 23 different charge states of Fe. Component 3 and 4 are more highly ionized and show absorption from only 9 different charge states of Fe, however we were able to reconstruct the absorption measure distribution (AMD) for all four. The total column density of each component is NH = (1.8+- 0.5) X10^22 cm-2, NH = (2.5+- 0.3) X10^22 cm-2, NH = (6.9+- 4.3) X10^22 cm-2 and NH = (5.4+- 1.2) X10^22 cm-2, respectively. The fast components 3 and 4 appear only in the high state of 2006 and not in 2001, while the slower components persist during both epochs. On the other hand, there is no significant absorption variability within days during 2001 or during 2006. We find that covering factor plays a minor role for the line absorption.

Boosting the Security of Blind Signature Schemes
Creators: name: Katz, Jonathan
name: Loss, Julian
name: Rosenberg, Michael
Publisher: name: CISPA
Year: 2023

description: Existing blind signature schemes that are secure for poly- nomially many concurrent executions of the signing protocol are either inefficient or rely on non-standard assumptions (even in the random-oracle model). We show the first efficient blind signature schemes achieving this level of security based on the RSA, factoring, or discrete-logarithm assumptions (in the random-oracle model). Our core technique involves an extension and generalization of a transform due to Pointcheval (Eurocrypt ’98) that allows us to boost the number of signatures supported by a certain class of blind signature schemes.

description: We show that the Wald Noether charge entropy is canonically conjugate to the opening angle at the horizon. Using this canonical relation we extend the Wheeler-DeWitt equation to a Schroedinger equation in the opening angle, following Carlip and Teitelboim. We solve the equation in the semiclassical approximation by using the correspondence principle and find that the solutions are minimal uncertainty wavefunctions with a continuous spectrum for the entropy and therefore also of the area of the black hole horizon. The fact that the opening angle fluctuates away from its classical value of 2 pi indicates that the quantum black hole is a superposition of horizonless states. The classical geometry with a horizon serves only to evaluate quantum expectation values in the strict classical limit.
