description: We report on a recently developed novel type of large area (62 mm x 62 mm) position sensitive silicon detector with four-corner readout. It consists of a square-shaped ion-implanted resistive anode framed by additional low-resistivity strips with resistances smaller than the anode surface resistance by a factor of 2. The detector position linearity, position resolution, and energy resolution were measured with alpha-particles and heavy ions. In-beam experimental results reveal a position resolution below 1 mm (FWHM) and a very good non-linearity of less than 1% (rms). The energy resolution determined from 228Th alpha source measurements is around 2% (FWHM).

description: We investigated the pressure-dependent optical response of the low-dimensional Mott-Hubbard insulator TiOBr by transmittance and reflectance measurements in the infrared and visible frequency range. A suppression of the transmittance above a critical pressure and a concomitant increase of the reflectance are observed, suggesting a pressure-induced metallization of TiOBr. The metallic phase of TiOBr at high pressure is confirmed by the presence of additional excitations extending down to the far-infrared range. The pressure-induced metallization coincides with a structural phase transition, according to the results of x-ray powder diffraction experiments under pressure.

description: The random sequential adsorption (RSA) model is modified to describe damage and crack accumulation. The exclusion for object deposition (for damaged region formation) is not for the whole object, as in the standard RSA, but only for the initial point (or higher-dimensional defect) from which the damaged region or crack initiates. The one-dimensional variant of the model is solved exactly.

Strategies for Increasing the Tracking Region of an Eye-in-Hand System by Singularity and Joint Limit Avoidance

Year: 1995
Subjects: subject: 80399 Computer Software not elsewhere classified

description: An eye-in-hand system visually tracking objects can fail when the manipulator encounters a kinematic singularity or a joint limit. A solution to this problem is presented in which objects are visually tracked while the manipulator simultaneously avoids kinematic singularities and manipulator joint limits by moving in directions along which the tracking task space is unconstrained or redundant. A manipulability measure is introduced into the visual tracking objective function, providing an elegant and robust technique for deriving a control law that visually tracks objects while accounting for the configuration of the manipulator. Two different tracking strategies, one using a standard visual tracking strategy and the other using the newly proposed strategy, are experimentally compared on an actual hand/eye system. The experimental results demonstrate the effectiveness of the new method by showing that the tracking region of a manipulator tracking objects with planar motion can be greatly increased.

description: Motivation: Measurements of gene expression over time enable the reconstruction of transcriptional networks. However, Bayesian networks and many other current reconstruction methods rely on assumptions that conflict with the differential equations that describe transcriptional kinetics. Practical approximations of kinetic models would enable inferring causal relationships between genes from expression data of microarray, tag-based and conventional platforms, but conclusions are sensitive to the assumptions made. Results: The representation of a sufficiently large portion of genome enables computation of an upper bound on how much confidence one may place in influences between genes on the basis of expression data. Information about which genes encode transcription factors is not necessary but may be incorporated if available. The methodology is generalized to cover cases in which expression measurements are missing for many of the genes that might control the transcription of the genes of interest. The assumption that the gene expression level is roughly proportional to the rate of translation led to better empirical performance than did either the assumption that the gene expression level is roughly proportional to the protein level or the Bayesian model average of both assumptions.

We searched for intra-day variability for 43 nights using quasi-simultaneous measurements in the B, V, R, and I bands (totaling 143 light curves); the typical sampling interval was about eight minutes. On hour-like timescales, BL Lac exhibited significant variations during 13 nights in various optical bands. Significant spectral variations are seen during most of these nights such that the optical spectrum becomes bluer when brighter. The amplitude of variability is usually greater for longer observations but is lower when BL Lac is brighter. No evidence for periodicities or characteristic variability time-scales in the light curves was found. The color variations are mildly chromatic on long timescales.

Playboys and the Cosmo Girls: Models of Femininity in Italian Men’s and Women’s Magazines and the Popularization of Feminist Knowledge*
Creators: name: Missero, Dalila
Publisher: name: AG About Gender - International Journal of Gender Studies
Year: 2019

description: Abstract This article offers a historical and textual reading of soft-core pornography in Italy by analyzing a group of men and women’s magazines, including the Italian editions of Playboy and Cosmopolitan, and the soft-core magazine for women, Libera, which was published from 1972 to 1978. As part of the ‘sexualization of western culture’ (Attwood 2009), porn produced new discourses regarding femininity, which openly challenged second-wave feminism and, at the same time, assimilated some of its aspects. Sexiness, self-care, monogamy and compulsory heterosexuality became foundational values for a new, modern, emancipated woman, one who was able to enjoy the benefits of the ‘sexual revolution’. Soft-core images also contributed to the spread of new knowledge about female sexuality, both in visual and narrative terms, and was also able to absorb some key aspects of the second-wave feminist political discourse on sexuality. In particular, the introduction of soft-core images in women’s magazines was presented as a ‘feminist move’ towards women’s empowerment. By illustrating the complex cultural function of soft-core pornography for women, this article aims to investigate the historical impact of porn in women’s lives and their relationship with popular culture. Keywords: soft-core pornography, women’s magazines, feminism, self-help, mass culture.

description: This paper deals with general structural properties of one-dimensional Schr"odinger operators with some absolutely continuous spectrum. The basic result says that the omega limit points of the potential under the shift map are reflectionless on the support of the absolutely continuous part of the spectral measure. This implies an Oracle Theorem for such potentials and Denisov-Rakhmanov type theorems. In the discrete case, for Jacobi operators, these issues were discussed in my recent paper [19]. The treatment of the continuous case in the present paper depends on the same basic ideas.

description: New techniques based on weak measurements have recently been introduced to the field of quantum state reconstruction. Some of them allow the direct measurement of each matrix element of an unknown density operator and need only $O(d)$ different operations, compared to $d^2$ linearly independent projectors in the case of standard quantum state tomography, for the reconstruction of an arbitrary mixed state. However, due to the weakness of these couplings, these protocols are approximated and prone to large statistical errors. We propose a method which is similar to the weak measurement protocols but works regardless of the coupling strength: our protocol is not approximated and thus improves the accuracy and precision of the results with respect to weak measurement schemes. We experimentally apply it to the polarization state of single photons and compare the results to those of preexisting methods for different values of the coupling strength. Our results show that our method outperforms previous proposals in terms of accuracy and statistical errors.

Between Sexual Objectification and Sexual Agency: the Most Watched Porn Videos in the Czech Republic
Creators: name: Lebedíková, Michaela
Publisher: name: AG About Gender - International Journal of Gender Studies
Year: 2019

description: Abstract In alignment with the feminist “sex wars,” sexual objectification and sexual agency are considered to be opposites that exclude each other. I used the sexual script theory to perform a qualitative content analysis of the five most-watched heterosexual porn videos in the Czech Republic on Pornhub. The study shows that although sexual objectification and agency are opposite types of behavior, they do not exclude each other; they intertwine. The levels of objectification and agency depend on the roles portrayed by the actors, but even though the women in the analyzed videos are cast in more sexually experienced roles, which grants them more sexual agency, they are still more objectified than the men. To my knowledge, this is the first study to measure how the levels of sexual objectification and sexual agency vary with the different genders of the actors. Keywords: sexual objectification, sexual agency, sexual scripts.

description: H.264/Advanced Video Coding (AVC) is one of the most commonly used video compression standard currently. In this paper, we propose a Reversible Data Hiding (RDH) method based on H.264/AVC videos. In the proposed method, the macroblocks with intra-frame $4\times 4$ prediction modes in intra frames are first selected as embeddable blocks. Then, the last zero Quantized Discrete Cosine Transform (QDCT) coefficients in all $4\times 4$ blocks of the embeddable macroblocks are paired. In the following, a modification mapping rule based on making full use of modification directions are given. Finally, each zero coefficient-pair is changed by combining the given mapping rule with the to-be-embedded information bits. Since most of last QDCT coefficients in all $4\times 4$ blocks are zero and they are located in high frequency area. Therefore, the proposed method can obtain high embedding capacity and low distortion.

From Porn Performer to Porntropreneur: Online Entrepreneurship, Social Media Branding, and Selfhood in Contemporary Trans Pornography
Creators: name: Pezzutto, Sophie
Publisher: name: AG About Gender - International Journal of Gender Studies
Year: 2019

description: Abstract Drawing on ten months of ethnographic field work in Las Vegas and Los Angeles, this article reflects on how transgender pornography performers navigate various economic, technological, and social changes confronting the industry. From the fracturing of the production landscape and the rise of social media platforms such as Twitter and Instagram, porn performers today operate in a vastly different environment than just two decades ago. Because they can no longer rely on big studios to provide them with a stable income, performers are much more productively thought of as entrepreneurs, or as I call it, porntropreneurs who are harnessing social media to earn income from a diverse range of erotic and sexual services that are based on a carefully curated personal brand. This personal brand extends into various aspects of their lives and shapes decisions from friendships to surgery. My research suggests that the most successful porn performers today embody a unique brand distinct from their competitors, often so all-encompassing that it can cause alienation. Reflecting on how transgender performers act as active agents situated within these technological, economic, and social structures can help us better understand subject formation in the context of 21st-century neoliberal internet capitalism. Keywords: transgender, pornography, online entrepreneurship, social media, personal branding.

description: “Robustness” is an overarching property of software systems that includes, to various viewers and to various extents, elements of correctness, reliability, fault-tolerance, performance, security, usability (without surprises), accuracy, and numerous other properties. Robustness is a form of dependability that focuses on resilience to failures. Many aspects of dependability and robustness have been explored extensively in the context of individual components. Modern software systems, however, are composed from multiple components. Often these components have not been designed to operate together. Increasingly these components are legacy code or even applications that can operate alone as well as in concert. Further, the components may be data or services as well as code. The challenge of individual components lies in understanding and managing the code, but the major challenge of modern systems lies in understanding and managing the interactions among the components. Large-scale system integration encounters new sources of problems, such as architectural mismatch, cross-platform portability, and side effects of evolution of the computing infrastructure. This new setting qualitatively changes the nature of the software development and integration process.

description: We show that an infinite dimensional Lie group in Milnor's sense has the strong Trotter property if it is locally $μ$-convex. This is a continuity condition imposed on the Lie group multiplication that generalizes the triangle inequality for locally convex vector spaces, and is equivalent to $C^0$-continuity of the evolution map on its domain. In particular, the result proven in this paper significantly extends the respective result obtained by Glöckner in the context of measurable regularity.

description: We computed the chemical evolution of spiral bulges hosting Seyfert nuclei, based on updated chemical and spectro-photometrical evolution models for the bulge of our Galaxy, made predictions about other quantities measured in Seyferts, and modeled the photometry of local bulges. The chemical evolution model contains detailed calculations of the Galactic potential and of the feedback from the central supermassive black hole, and the spectro-photometric model covers a wide range of stellar ages and metallicities. We followed the evolution of bulges in the mass range 10^9 - 10^{11} Msun by scaling the star formation efficiency and the bulge scalelength as in the inverse-wind scenario for elliptical galaxies, and considering an Eddington limited accretion onto the central supermassive black hole. We successfully reproduced the observed black hole-host bulge mass relation. The observed nuclear bolometric luminosity is reproduced only at high redshift or for the most massive bulges; in the other cases, at z = 0 a rejuvenation mechanism is necessary. The black hole feedback is in most cases not significant in triggering the galactic wind. The observed high star formation rates and metal overabundances are easily achieved, as well as the constancy of chemical abundances with redshift and the bulge present-day colours. Those results are not affected if we vary the index of the stellar IMF from x=0.95 to x=1.35; a steeper IMF is instead required in order to reproduce the colour-magnitude relation and the present K-band luminosity of the bulge.

description: Galaxy formation inside dark matter halos, as well as the halo formation itself, can be affected by large-scale environments. Evaluating the imprints of environmental effects on galaxy clustering is crucial for precise cosmological constraints with data from galaxy redshift surveys. We investigate such an environmental impact on both real-space and redshift-space galaxy clustering statistics using a semi-analytic model derived from the Millennium Simulation. We compare clustering statistics from original SAM galaxy samples and shuffled ones with environmental influence on galaxy properties eliminated. Among the luminosity-threshold samples examined, the one with the lowest threshold luminosity (~0.2L_*) is affected by environmental effects the most, which has a ~10% decrease in the real-space two-point correlation function (2PCF) after shuffling. By decomposing the 2PCF into five different components based on the source of pairs, we show that the change in the 2PCF can be explained by the age and richness dependence of halo clustering. The 2PCFs in redshift space are found to change in a similar manner after shuffling. If the environmental effects are neglected, halo occupation distribution modeling of the real-space and redshift-space clustering may have a less than 6.5% systematic uncertainty in constraining beta from the most affected SAM sample and have substantially smaller uncertainties from the other, more luminous samples. We argue that the effect could be even smaller in reality. In the Appendix, we present a method to decompose the 2PCF, which can be applied to measure the two-point auto-correlation functions of galaxy sub-samples in a volume-limited galaxy sample and their two-point cross-correlation functions in a single run utilizing only one random catalog.

Multi-wavelength Intra-day Variability and Quasi-periodic Oscillation in Blazars

description: We reviewed multi-wavelength blazars variability and detection of quasi-periodic oscillations on intra-day timescales. The variability timescale from few minutes to up to less than a days is commonly known as intra-day variability. These fast variations are extremely useful to constrain the size of emitting region, black hole mass estimation, etc. It is noticed that in general blazars show intra-day variability in the complete electromagnetic spectrum. But some class of blazars either do not show or show very little intra-day variability in a specific band of electromagnetic spectrum. Blazars show rarely quasi-periodic oscillations in time series data in optical and X-ray bands. Other properties and emission mechanism of blazars are also briefly discussed.

description: Recent developments of quantum information science critically rely on entanglement, an intriguing aspect of quantum mechanics where parts of a composite system can exhibit correlations stronger than any classical counterpart. In particular, scalable quantum networks require capabilities to create, store, and distribute entanglement among distant matter nodes via photonic channels. Atomic ensembles can play the role of such nodes. So far, in the photon counting regime, heralded entanglement between atomic ensembles has been successfully demonstrated via probabilistic protocols. However, an inherent drawback of this approach is the compromise between the amount of entanglement and its preparation probability, leading intrinsically to low count rate for high entanglement. Here we report a protocol where entanglement between two atomic ensembles is created by coherent mapping of an entangled state of light. By splitting a single-photon and subsequent state transfer, we separate the generation of entanglement and its storage. After a programmable delay, the stored entanglement is mapped back into photonic modes with overall efficiency of 17 %. Improvements of single-photon sources together with our protocol will enable "on demand" entanglement of atomic ensembles, a powerful resource for quantum networking.

Subscription Intimacy: Amateurism, Authenticity and Emotional Labour in Direct-to-Consumer Gay Pornography
Creators: name: Laurin, Daniel

description: Abstract: As pornography studios deal with declining profits and performers work to survive on decreasing scene rates, direct-to-consumer platforms such as OnlyFans are being hailed by some as saviours of the industry. Exemplifying the promises of the current gig economy, these platforms claim to offer supplemental income and autonomy and have been praised by journalists as addressing market demand for intimacy in a mainstream pornographic landscape largely devoid of it. But these platforms can also be seen as another example of the emotional labour that is increasingly required of porn performers. This includes performers depicting “authentic” desire in their videos, participating in on-camera interviews, and engaging with fans across multiple social media networks with differing regulations around nudity that can be challenging for adult performers to navigate. This article situates these direct-to-consumer platforms within the larger history of gay porn production, amateur video, and discourses of authenticity, and considers the possibilities of monetizing new forms of emotional labour, or what I refer to as “subscription intimacy.” Keywords: gay pornography, authenticity, amateur pornography, emotional labour, social media.

description: Excited state soliton stars are studied numerically for the first time. The stability of spherically symmetric S-branch excited state oscillatons under radial perturbations is investigated using a 1D code. We find that these stars are inherently unstable either migrating to the ground state or collapsing to black holes. Higher excited state configurations are observed to cascade through intermediate excited states during their migration to the ground state. This is similar to excited state boson stars. Ground state oscillatons are then studied in full 3D numerical relativity. Finding the appropriate gauge condition for the dynamic oscillatons is much more challenging than in the case of boson stars. Different slicing conditions are explored, and a customized gauge condition that approximates polar slicing in spherical symmetry is implemented. Comparisons with 1D results and convergence tests are performed. The behavior of these stars under small axisymmetric perturbations is studied and gravitational waveforms are extracted. We find that the gravitational waves damp out on a short timescale, enabling us to obtain the complete waveform. This work is a starting point for the evolution of real scalar field systems with arbitrary symmetries.

From Amateur Aesthetics to Intelligible Orgasms: Pornographic Authenticity and Precarious Labour in the Gig Economy
Creators: name: Stardust, Zahra Zsuzsanna
Publisher: name: AG About Gender - International Journal of Gender Studies
Year: 2019

description: Abstract Authenticity has been described as a hallmark of alternative pornographies, reframing porn producers as documentarians and professing an increased investment in ‘real’ bodies, unscripted sex and genuine pleasures. In this article I examine what authenticity means to pornography producers and performers via autoethnography and 20 qualitative interviews. Fantasies of authenticity among producers often reflected particular iterations of white, middle class femininity and conventionalised signifiers of ‘naturalness’ that were presumed intelligible to audiences. Authenticity was often staged, imagined and projected by producers, who in some cases assessed the authenticity of their performers’ orgasms. In contrast, performers, who worked across genres, strategically navigated producer requirements and were more concerned with transparency, expectation management and contractual obligations. I argue that authenticity narratives form part of a wider cultural imperative for sex workers to describe their work as personal identity or sexual expression. They also manifest in a context of income precarity and job insecurity where performers need to maintain open avenues of potential work. Where authenticity becomes an aesthetic regime of its own, it produces new hierarchies of representation. Instead of undoing binaries between “fake” versus “real” sex, authenticity narratives can serve to construct and repudiate narratives of artifice as a means to displace stigma and obscure the gendered, aspirational and relational labour of porn performers. Keywords: authenticity, feminist pornography,labour, gig economy, sex work.

description: Human Computer Interaction (HCI) is the study of how people design, implement, and use interactive computer systems, and how computers affect individuals, organizations, and society. HCI is a research area of increasingly central significance to computer science, other scientific and engineering disciplines, and an ever expanding array of application domains. This more prominent role follows from the widely perceived need to expand the focus of computer science research beyond traditional hardware and software issues to attempt to better understand how technology can more effectively support people in accomplishing their goals. At the same time that a human-centered approach to system development is of growing significance, factors conspire to make the design and development of systems even more difficult than in the past. This increased difficulty follows from the disappearance of boundaries between applications as we start to support people's real activities; between machines as we move to distributed computing; between media as we expand systems to include video, sound, graphics, and communication facilities; and between people as we begin to realize the importance of supporting organizations and group activities. This report summarizes selected strategic directions in human computer interaction research, sets them within an historical context of research accomplishments, and tries to convey not only the significance but the excitement of the field.

Implicative algebras: a new foundation for realizability and forcing

description: We introduce the notion of implicative algebra, a simple algebraic structure intended to factorize the model constructions underlying forcing and realizability (both in intuitionistic and classical logic). The salient feature of this structure is that its elements can be seen both as truth values and as (generalized) realizers, thus blurring the frontier between proofs and types. We show that each implicative algebra induces a (Set-based) tripos, using a construction that is reminiscent from the construction of a realizability tripos from a partial combinatory algebra. Relating this construction with the corresponding constructions in forcing and realizability, we conclude that the class of implicative triposes encompass all forcing triposes (both intuitionistic and classical), all classical realizability triposes (in the sense of Krivine) and all intuitionistic realizability triposes built from partial combinatory algebras.

description: Requirements for high availability in computing systems today demand that systems be self-adaptive to maintain expected qualities-of-service in the presence of system faults, variable environmental conditions, and changing user requirements. Autonomic computing tackles the challenge of automating tasks that humans would otherwise have to perform to achieve this goal. However, existing approaches to autonomic computing lack the ability to capture routine human repair tasks in a way that takes into account the business context humans use in selecting an appropriate form of adaptation, while dealing with timing delays and uncertainties in outcome of repair actions. In this article, we present Stitch, a language for representing repair strategies within the context of an architecture-based self-adaptation framework. Stitch supports the explicit representation of repair decision trees together with the ability to express business objectives, allowing a self-adaptive system to select a strategy that has optimal utility in a given context, even in the presence of potential timing delays and outcome uncertainty.
Evidence for Non-Hydrostatic Gas from the Cluster X-ray to Lensing Mass Ratio

description: Using a uniform analysis procedure, we measure spatially resolved weak gravitational lensing and hydrostatic X-ray masses for a sample of 18 clusters of galaxies. We find a radial trend in the X-ray to lensing mass ratio: at r2500 we obtain a ratio MX/ML=1.03+/-0.07 which decreases to MX/ML=0.78+/-0.09 at r500. This difference is significant at 3 sigma once we account for correlations between the measurements. We show that correcting the lensing mass for excess correlated structure outside the virial radius slightly reduces, but does not eliminate this trend. An X-ray mass underestimate, perhaps due to nonthermal pressure support, can explain the residual trend. The trend is not correlated with the presence or absence of a cool core. We also examine the cluster gas fraction and find no correlation with ML, an important result for techniques that aim to determine cosmological parameters using the gas fraction.

description: Our knowledge about the "cold" Universe often relies on molecular spectra. A general property of such spectra is that the energy level populations are rarely at local thermodynamic equilibrium. Solving the radiative transfer thus requires the availability of collisional rate coefficients with the main colliding partners over the temperature range 10-1000 K. These rate coefficients are notoriously difficult to measure and expensive to compute. In particular, very few reliable collisional data exist for collisions involving reactive radicals or ions. Here we explore the use of a fast quantum statistical method to determine molecular collisional excitation rate coefficients. The method is benchmarked against accurate (but costly) close-coupling calculations. For collisions proceeding through the formation of a strongly-bound complex, the method is found to be highly satisfactory up to room temperature. Its accuracy decreases with the potential well depth and with increasing temperature, as expected. This new method opens the way to the determination of accurate inelastic collisional data involving key reactive species such as H3+, H2O+, and H3O+ for which exact quantum calculations are currently not feasible.

description: The meaningful comparison of models of galaxy evolution to observations is critically dependent on the accurate treatment of dust attenuation. To investigate dust absorption and emission in galaxies we have assembled a sample of ~1000 galaxies with ultraviolet (UV) through infrared (IR) photometry from GALEX, SDSS, and Spitzer and optical spectroscopy from SDSS. The ratio of IR to UV emission (IRX) is used to constrain the dust attenuation in galaxies. We use the 4000A break as a robust and useful, although coarse, indicator of star formation history (SFH). We examine the relationship between IRX and the UV spectral slope (a common attenuation indicator at high-redshift) and find little dependence of the scatter on 4000A break strength. We construct average UV through far-IR spectral energy distributions (SEDs) for different ranges of IRX, 4000A break strength, and stellar mass (M_*) to show the variation of the entire SED with these parameters. When binned simultaneously by IRX, 4000A break strength, and M_* these SEDs allow us to determine a low resolution average attenuation curve for different ranges of M_*. The attenuation curves thus derived are consistent with a lambda^{-0.7} attenuation law, and we find no significant variations with M_*. Finally, we show the relationship between IRX and the global stellar mass surface density and gas-phase-metallicity. Among star forming galaxies we find a strong correlation between IRX and stellar mass surface density, even at constant metallicity, a result that is closely linked to the well-known correlation between IRX and star-formation rate.

description: We consider the modified Einstein equations obtained in the framework of effective spherically symmetric polymer models inspired by Loop Quantum Gravity. When one takes into account the anomaly free point-wise holonomy quantum corrections, the modification of Einstein equations is parametrized by a function $f(x)$ of one phase space variable. We solve explicitly these equations for a static interior black hole geometry and find the effective metric describing the trapped region, inside the black hole, for any $f(x)$. This general resolution allows to take into account a standard ambiguity inherent to the polymer regularization: namely the choice of the spin $j$ labelling the SU$(2)$-representation of the holonomy corrections. When $j=1/2$, the function $f(x)$ is the usual sine function used in the polymer litterature. For this simple case, the effective exterior metric remains the classical Schwarzschild's one but acquires modifications inside the hole. The interior metric describes a regular trapped region and presents strong similarities with the Reissner-Nordström metric, with a new inner horizon generated by quantum effects. We discuss the gluing of our interior solution to the exterior Schwarzschild metric and the challenge to extend the solution outside the trapped region due to covariance requirement. By starting from the anomaly free polymer regularization for inhomogeneous spherically symmetric geometry, and then reducing to the homogeneous interior problem, we provide an alternative treatment to existing polymer interior black hole models which focus directly on the interior geometry, ignoring covariance issue when introducing the polymer regularization.
