description: There were one hundred college students in a private university in Metro Manila surveyed through developed and self-developed research instruments to determine their HIV awareness through Grindr, a gay dating application. Additional self-developed research instrument was used for key informants, which answers supported results on communication and use of Grindr by the respondents. Presumed on the New Media Theory by Vogt (2017), the study determined the correlation between the independent variables (communication and use of Grindr, HIV awareness, Grindr engagements, HIV infection consciousness, expert's view on HIV awareness) and the dependent variable (contents for the proposed NSTP subject). On the other hand, mediating variables on socio-demographic characteristics of respondents (age, year level, course, sexual role, relationship status, purpose in using Grindr, Grindr activities) also used the theory to test its relevancy. Relationships were tested and were set at 0.05 levels of significance. One way Analysis of Variance (ANOVA) was used to test the significance of the means and t-test as well as z-test for independent means as intra test. The results generated from the study revealed that college students were not fully aware of the HIV infection until infected with the virus. The study simply interpreted the result that Grindr, as gay dating applications is not focusing on HIV, but heavily on gay dating. Though, HIV awareness is visible in Grindr, the attitudes and values of college students subscribing Grindr implies high risk of getting HIV infection.

description: The LHC search for nearly degenerate gluinos and neutralinos, which can occur, for example, in SUSY axion models, is limited by the reduced missing transverse momentum and effective mass in the events. We propose the use of kinematic correlations between jets coming from initial state radiation (ISR) in gluino pair production events at the 13 TeV LHC. A significant improvement in the signal to background ratio is obtained for the highly compressed gluino-neutralino search, by using cuts on the rapidity and azimuthal angle separation between the pair of tagged jets with the highest transverse momenta. Furthermore, the distribution of the azimuthal angle difference between the tagged jets in the gluino-pair+jets process is found to be distinctly different from the dominant background process of Z+jets. We also find quark and gluon jet tagging methods to be useful in separating the signal, which contains a higher fraction of gluon initiated jets compared to the dominant backgrounds.

description: Tunneling in a quantum coherent structure is not restricted to only nearest neighbours. Hopping between distant sites is possible via the virtual occupation of otherwise avoided intermediate states. Here we report the observation of long range transitions in the transport through three quantum dots coupled in series. A single electron is delocalized between the left and right quantum dots while the centre one remains always empty. Superpositions are formed and both charge and spin are exchanged between the outermost dots. Detection of the process is achieved via the observation of narrow resonances, insensitive to the transport Pauli spin blockade.

description: Background
Tumors of the infraorbital malar region require aesthetic reconstruction of the anatomy and function, which sometimes represents a surgical challenge (3). They require complex procedures, especially when they involve the lower eyelid, even more when the full thickness of the eyelid is affected, skin, muscle, tarsus and conjunctiva (4).We present the case of a male in the ninth decade of life with a diagnosis of well-differentiated, keratinizing, warty squamous cell carcinoma infiltrating the deep dermis by incisional biopsy of the left cheek. Repair of the malar region was performed using a Mustardé-type advancement and rotation flap. Reconstruction of the malar region involves adequate resection of the tumor (full thickness) and subsequent dissection of the cheek rotation flap which is appropriately thinned at its upper edge and mobilized to form the skin layer. A flap of this nature must be dissected into the subcutaneous tissue layer allowing a tension- free flap providing support and stability to the recipient area (5).

description: To optimize the project outcomes, D5.2 Integrated BEACONING platform test analysis focuses on testing the components’ readiness for integration and the platform integration workflows, in order to ensure a streamlined interaction for end-users across the platform components. The deliverable builds upon the outcomes of D3.6 System architecture and the initial outcomes of T5.1 Test of the single components. In M18, the key BEACONING components were partly ready for testing (Alpha version of the Platform), and a global test can be performed in M28 when the integrated BEACONING Ecosystem is due. This deliverable includes test cards for testing component-to-component integration. It also includes theoretical guidelines for the testing when not feasible to actually test components at this point. It describes possible risks and recommendations for risk mitigation. When all of the components have been completed, performance evaluation will involve a review of the integration phase of the system and a global test to verify the performance of the system in a laboratory environment. The tests will include assessment of accuracy, general system reliability, communication performance between multi-agents, and usability. The validation will also be in-line with the pre-pilot stage (for WP6) in order to evaluate the proposed indicators and measures for pre-pilot readiness.

description: In this article, we show how freemium business models can deter piracy. We analyze a simple freemium model in which a firm offers both a free version and a premium version. The firm can restrict the use of the free version. Consumers can choose between the free and the premium version, but can also get an illegal digital copy. More restrictions can increase the number of premium users but divert other users to piracy. On the contrary, fewer restrictions deter online piracy. We show that with a low level of piracy, the firm sets a high level of restrictions on the free version, which makes the traditional premium business model more profitable than the freemium model. We therefore challenge the idea that strong copyright laws are necessary to protect digital markets. We argue that there are market solutions to fight free with free that better segment consumer audiences according to their willingness to pay for digital music.

description: We anticipate the first direct detections of gravitational waves (GWs) with Advanced LIGO and Virgo later this decade. Though this groundbreaking technical achievement will be its own reward, a still greater prize could be observations of compact binary mergers in both gravitational and electromagnetic channels simultaneously. During Advanced LIGO and Virgo's first two years of operation, 2015 through 2016, we expect the global GW detector array to improve in sensitivity and livetime and expand from two to three detectors. We model the detection rate and the sky localization accuracy for binary neutron star (BNS) mergers across this transition. We have analyzed a large, astrophysically motivated source population using real-time detection and sky localization codes and higher-latency parameter estimation codes that have been expressly built for operation in the Advanced LIGO/Virgo era. We show that for most BNS events the rapid sky localization, available about a minute after a detection, is as accurate as the full parameter estimation. We demonstrate that Advanced Virgo will play an important role in sky localization, even though it is anticipated to come online with only one-third as much sensitivity as the Advanced LIGO detectors. We find that the median 90% confidence region shrinks from ~500 square degrees in 2015 to ~200 square degrees in 2016. A few distinct scenarios for the first LIGO/Virgo detections emerge from our simulations.

description: We expose an intrinsic stability problem in joint calibration of a LIBOR market model to caps and swaptions by direct least squares calibration. This problem typically encounters if one tries to identify jointly the volatility norm behaviour and the correlation structure of the forward LIBORs. As a remedy we propose collateral incorporation of a 'Market Swaption Formula', a rule-of-thumb formula which practitioners tend to use, in the calibration routine. It is shown by experiments with practical data that with this new calibration procedure and suitably parametrized volatility structures LIBOR model calibration to caps and swaptions is stable. The involved calibration routine is based on standard swaption approximation or its refinements by Hull & White, Jäckel & Rebonato. We deal with the issue of differently settled caps and swaptions by accordingly adapting the swap rate formula and give a respective modification of Jäckel and Rebonato's refined swaption approximation formula.

description: BEACONING is an ecosystem. It means BEACONING implements a set of components and processes that depend on each other and interact with the same unifying purpose: to drive pervasive game-based learning experiences.

The core BEACONING Platform supports services and a communication framework with a focus on interoperability standards and governing industrial practices1. Around the core platform, a set of components such as the authoring tool, the game and graphics engine, the geolocation game engine and mini-games are applications that utilize a reuse-driven assets library. A set of industry standards enable the interoperability and coupling of these units. The platform integrates with learning management systems, collaborative learning platforms and context-awareness providers via a set of industry standards. Communication between the units, at data level communication rely two types of data models: standards (as ADL xAPI standard); and custom, developed within the project using JSON format for describing embedded mini-games and for describing Gamified Lesson Paths and can simply inform future standards.

This document is the “Intermediate” version of the standardization in BEACONING Ecosystem, briefing the elements of interoperability and coherence among the components.

description: Nowadays, Internet of Things (IoT) devices are used in various fields such as health-care, agriculture and smart cities. They continuously generate a large amount ofdata needed to be stored and analyzed. Preserving such data, especially image data,presents a challenge as storage resources are mostly limited. Techniques like real-time object detection have been applied to save only some information about theimage data. However, such techniques limit the possibilities of doing a broaderanalysis of image data. This problem underlines the importance of data compres-sion at the edge, the process in which the size of the data is reduced. It has a directinfluence on increasing network bandwidth and decreasing transmission latency.In this work, we present an online-lossy compression algorithm by means of asymbolic representation of image data. Lossy compression, unlike lossless compres-sion, allows a loss of original information to an allowable extent. Thus, only anapproximation of an image can be reconstructed back.The proposed method uses a modified Adaptive Brownian Bridge Aggregation(fABBA) algorithm to compress the selected Urban Tracker image data at the edge.We showed the importance and upper-lower bounds of hyper-parameters suitablefor image data and fixed the hash-map for online compression. Further, as for theanalysis part, we have compared the object detection from reconstructed images andoriginal (not compressed) images.Our results show that the compression algorithm achieves up to 30% reductionand has 0.886 mAP from object detection. Moreover, we showed that dependingon the image processing task, two adaptive hyper-parameters can have upper andlower bounds.

description: Time-sharing Experiments for the Social Sciences (TESS) offers researchers the opportunity to capture the internal validity of experiments. Investigators submit proposals, and TESS fields successful proposals for free on a representative sample of adults in the United States. This experiment was conducted to examine the extent to which the use of the term “Democrat Party,” compared to the official name of the party, the “Democratic Party,” influences perceptions of a politician and how these effects differ between self-identified Republicans and Democrats. Respondents were randomly assigned to one of two treatments which presented a quote from a Republican official decrying either the “Democrat Party” or “Democratic Party." A total of 2,009 respondents participated. All respondents were asked to rate the official’s likability and competence. This allowed for comparison of perceptions across treatment groups and demographics.

description: We consider the possibility of formation of cosmic strings with black holes as beads. We focus on the simplest setup where two black holes are formed on a long cosmic string. It turns out the in absence of a background magnetic field and for observationally viable values for cosmic string tensions, $μ<2\times 10^{-7}$, the tension of the strut in between the black holes has to be less than the ones that run into infinity. This result does not change if a cosmological constant is present. However if the background magnetic field is turned on, we can have stable setups where the tensions of all cosmic strings are equal. We derive the equilibrium conditions in each of these setups depending on whether the black holes are extremal or non-extremal. We obtain cosmologically acceptable solutions with solar mass black holes and intragalactic strength cosmic magnatic field.

Investigators submit proposals, and TESS fields successful proposals for free on a representative sample of adults in the United States. This experiment was conducted to examine the perceptions of Asian-ness among American voters and how these perceptions affect candidate evaluations in elections. Respondents were randomly assigned to one of five priming treatments which manipulated the national origin background (Indian, Chinese, Vietnamese, Black, control) of a fictional female mayoral candidate and then measured respondents’ perceptions around the politician’s ability to represent the Asian American community. A total of 3,180 respondents participated. This allowed for comparison of voter perceptions and identification of the role of an Asian candidate’s national origin background on voter attitudes.
A Computation Offloading Incentive Mechanism with Delay and Cost Constraints under 5G Satellite-Ground IoV Architecture

Subjects: cs.NI

description: © 2002-2012 IEEE. The 5G Internet of Vehicles has become a new paradigm alongside the growing popularity and variety of computation-intensive applications with high requirements for computational resources and analysis capabilities. Existing network architectures and resource management mechanisms may not sufficiently guarantee satisfactory Quality of Experience and network efficiency, mainly suffering from the coverage limitation of road side units, unsatisfactory computational resources and capabilities of onboard equipment, frequently changing network topologies, and ineffective resource management schemes. To meet the demands of such applications, in this article we first establish a novel architecture by integrating the satellite network with the 5G cloud-enabled Internet of Vehicles to efficiently support seamless coverage and efficient resource management. An incentive mechanism based joint optimization problem of opportunistic computation offloading under delay and cost constraints is formulated under the proposed 5G integrated satellite-ground framework, where a vehicular user can either be a service requestor allowed to offload workload to nearby vehicles via vehicle-to-vehicle channels while effectively controlling the cost, or a service provider who provides computing services while protecting profits. As the optimization problem is non-convex and NP-hard, simulated annealing based on the Markov Chain Monte Carlo as well as the metropolis algorithm is applied which can efficaciously obtain both high-quality and cost-effective approximations of global optimal solutions. The effectiveness of the proposed mechanism is corroborated through simulation results.

description: The intense radiation flux of Type I X-ray bursts is expected to interact with the accretion flow around neutron stars. High frequency quasiperiodic oscillations (kHz QPOs), observed at frequencies matching orbital frequencies at tens of gravitational radii, offer a unique probe of the innermost disk regions. In this paper, we follow the lower kHz QPOs, in response to Type I X-ray bursts, in two prototypical QPO sources, namely 4U 1636-536 and 4U 1608-522, as observed by the Proportional Counter Array of the Rossi X-ray Timing Explorer. We have selected a sample of 15 bursts for which the kHz QPO frequency can be tracked on timescales commensurable with the burst durations (tens of seconds). We find evidence that the QPOs are affected for over ~200 s during one exceptionally long burst and ~100 s during two others (although at a less significant level), while the burst emission has already decayed to a level that would enable the pre-burst QPO to be detected. On the other hand, for most of our burst-kHz QPO sample, we show that the QPO is detected as soon as the statistics allow and in the best cases, we are able to set an upper limit of ~20 s on the recovery time of the QPO. This diversity of behavior cannot be related to differences in burst peak luminosity. We discuss these results in the framework of recent findings that accretion onto the neutron star may be enhanced during Type I X-ray bursts. The subsequent disk depletion could explain the disappearance of the QPO for ~100 s, as possibly observed in two events. However, alternative scenarios would have to be invoked for explaining the short recovery timescales inferred from most bursts. Clearly the combination of fast timing and spectral information of Type I X-ray bursts holds great potential in the study of the dynamics of the inner accretion flow around neutron stars.

description: Using a hybrid density-functional theory (DFT) calculation including spin-orbit coupling (SOC), we predict that the zigzag antiferromagnetic (AFM) ground state of the honeycomb layered compound Na2IrO3 opens the observed insulating gap through a long-range magnetic order. We show that the effect of SOC and the correction of self-interaction error inherent in previous local or semilocal DFT calculations play crucial roles in predicting the band gap formation in Na2IrO3. It is revealed that the itinerant AFM order with a strong suppression of the Ir magnetic moment is attributed to a considerable hybridization of the Ir 5d orbitals with the O 2p orbitals. Thus, our results suggest that the insulating phase of Na2IrO3 can be represented as a Slater insulator driven by itinerant magnetism.

We also interpret the $1/\sqrt{t}$ correction to the average position of the rightmost particle of a branching random walk for large times $t\gg 1$, computed by Ebert and Van Saarloos, as fluctuations on top of the mean-field approximation of this process with a Brunet-Derrida cutoff at the tip that simulates discreteness. Our analytical formulas successfully compare to numerical simulations of a particular model of branching random walk.

description: The scattering of two-dimensional massless Dirac fermions from local spin-orbit interactions with an origin in dilute concentrations of physisorbed atomic species on graphene is theoretically investigated. The hybridization between graphene and the adatoms' orbitals lifts spin and valley degeneracies of the pristine host material, giving rise to rich spin-orbit coupling mechanisms with features determined by the exact adsorption position on the honeycomb lattice - bridge, hollow or top position - and the adatoms' outer-shell orbital type. Effective graphene-only Hamiltonians are derived from symmetry considerations, while a microscopic tight-binding approach connects effective low-energy couplings and graphene-adatom hybridization parameters. Within the $T$-matrix formalism, a theory for (spin-dependent) scattering events involving graphene's charge carriers, and the spin-orbit active adatoms is developed. Spin currents associated with intravalley and intervalley scattering are found to tend to oppose each other. We establish that under certain conditions, hollow-position adatoms give rise to the spin Hall effect, through skew scattering, while top-position adatoms induce transverse charge currents via trigonal potential scattering. We also identify the critical Fermi energy range where the spin Hall effect is dramatically enhanced, and the associated transverse spin currents can be reversed.

TESS Experiments: Blame and Bias in Trust in Public Policy Algorithms, Experiment A
Creators: name: Ozer, Adam
Publisher: name: Roper Center for Public Opinion Research
Year: 2023

description: Time-sharing Experiments for the Social Sciences (TESS) offers researchers the opportunity to capture the internal validity of experiments. Investigators submit proposals, and TESS fields successful proposals for free on a representative sample of adults in the United States. This question was asked as part of an experiment to examine how the use of algorithms affect public placement of blame on public officials. Respondents were randomly assigned to one of seven vignettes describing a judge’s decision in relation to a drunk driving case in which a previous offender was granted probation on the second offense and then repeated the offense a third time, killing another in the process. Vignettes varied the actor(s) responsible for the ruling (judge only (control); probation officer recommendation for probation, probation officer recommendation for imprisonment, probation officer and algorithm recommendation for probation, probation officer and algorithm recommendation for imprisonment, algorithm only recommendation for probation, algorithm only recommendation for imprisonment). A total of 1,846 respondents participated. Respondents were asked how much blame they attribute to each of the actors in the vignette presented. This allowed for comparison of perceptions of government accountability across conditions.

description: The inclusive Higgs production rate through gluon fusion has been measured to be in agreement with the Standard Model (SM). We show that even if the inclusive Higgs production rate is very SM-like, a precise determination of the boosted Higgs transverse momentum shape offers the opportunity to see effects of natural new physics. These measurements are generically motivated by effective field theory arguments and specifically in extensions of the SM with a natural weak scale, like composite Higgs models and natural supersymmetry. We show in detail how a measurement at high transverse momentum of $H\to 2\ell+\mathbf{p}\!\!/_T$ via $H\to ττ$ and $H\to WW^*$ could be performed and demonstrate that it offers a compelling alternative to the $t\bar t H$ channel. We discuss the sensitivity to new physics in the most challenging scenario of an exactly SM-like inclusive Higgs cross-section.

description: The standard three-neutrino (3nu) oscillation framework is being increasingly refined by results coming from different sets of experiments, using neutrinos from solar, atmospheric, accelerator and reactor sources. At present, each of the known oscillation parameters [the two squared mass gaps (delta m^2, Delta m^2) and the three mixing angles (theta_12}, theta_13, theta_23)] is dominantly determined by a single class of experiments. Conversely, the unknown parameters [the mass hierarchy, the theta_23 octant and the CP-violating phase delta] can be currently constrained only through a combined analysis of various (eventually all) classes of experiments. In the light of recent new results coming from reactor and accelerator experiments, and of their interplay with solar and atmospheric data, we update the estimated N-sigma ranges of the known 3nu parameters, and revisit the status of the unknown ones. Concerning the hierarchy, no significant difference emerges between normal and inverted mass ordering. A slight overall preference is found for theta_23 in the first octant and for nonzero CP violation with sin delta < 0; however, for both parameters, such preference exceeds 1 sigma only for normal hierarchy. We also discuss the correlations and stability of the oscillation parameters within different combinations of data sets.

description: Coherent boundaries of Lagrangian vortices in fluid flows have recently been identified as closed orbits of line fields associated with the Cauchy-Green strain tensor. Here we develop a fully automated procedure for the detection of such closed orbits in large-scale velocity data sets. We illustrate the power of our method on ocean surface velocities derived from satellite altimetry.

Cooperative robustness to dephasing: single-exciton Superradiance in a nanoscale ring to model natural light-harvesting systems

description: We analyze a 1-d ring structure composed of many two-levels systems, in the limit where only one excitation is present. The two-levels systems are coupled to a common environment, where the excitation can be lost, which induces super and subradiant behavior. Moreover, each two-levels system is coupled to another independent environment, modeled by a classical white noise, simulating a dephasing bath and described by the Haken-Strobl master equation. Single exciton Superradiance, an example of cooperative quantum coherent effect, is destroyed at a critical dephasing strength proportional to the system size, showing robustness of cooperativity to the action of the dephasing environment. We also show that the coupling to a common decay channel contrasts the action of dephasing, driving the entanglement decay to slow down on increasing the system size. Moreover, after a projective measurement which finds the excitation in the system, the entanglement reaches a stationary value, independent of the initial conditions.
