CREATIVITY = INTELLIGENCE + INTUITION? THE RELATIONSHIPS BETWEEN INTUITION, CREATIVITY, AND INTELLIGENCE

The study examined intuition and its relations with intelligence and creativity. Based on anecdotal evidence and past empirical research, it was hypothesized that measures of intuition, including implicit learning, would be related to each other. Furthermore, two hypotheses were explored: First, individual differences in creativity can be predicted by intelligence and intuition, and second, individual differences in intelligence can be predicted by creativity and intuition. Sixty eight participants completed various measures of intuition, an implicit learning task, and tests of creativity and intelligence. Self-report measures of intuition correlated with each other, but not with measures of implicit learning. Some limited support for the first hypothesis was found, but support for the second hypothesis was stronger. Measures of intuition, in combination with measures of creativity, were able to predict intelligence to a significant degree. Several other relationships were also examined. Implications and suggestions for future research are discussed

Does Anyone Really Like Horror Movies? Personality and Automatic Affective Reactions to Frightening Films

I sought to explain why many people willingly expose themselves to apparently unpleasant media, such as horror movies. Participants (N = 133) completed a modified version of the Affect Misattribution Procedure (AMP; Payne et al., 2005), which assessed initial affective reactions to screenshots from movies that were either frightening or neutral. The time between exposure to the screenshots and assessment of affect was either short (100 ms) or long (1000 ms). Explicit attitudes about the movies and about the horror genre were also assessed, in addition to the following personality variables: The Big Five, Machiavellianism (from the Supernumerary Personality Inventory), Sensation Seeking, and Psychopathy. There was little evidence for a direct connection between implicit reactions and explicit attitudes, but I found overall support for an aftermath- based model of horror enjoyment, in which affect gets increasingly positive after a horrific stimulus has been removed from the screen. However, this relief-like pattern was moderated by Agreeableness and Sensation Seeking. Personality correlates of horror liking (both explicit and implicit) were examined. Furthermore, gender differences supported a gender socialization theory of reactions to frightening media. Theoretical implications and practical applications are discussed

Pulsing corals: A story of scale and mixing

Effective methods of fluid transport vary across scale. A commonly used dimensionless number for quantifying the effective scale of fluid transport is the Reynolds number, Re, which gives the ratio of inertial to viscous forces. What may work well for one Re regime may not produce significant flows for another. These differences in scale have implications for many organisms, ranging from the mechanics of how organisms move through their fluid environment to how hearts pump at various stages in development. Some organisms, such as soft pulsing corals, actively contract their tentacles to generate mixing currents that enhance photosynthesis. Their unique morphology and intermediate scale where both viscous and inertial forces are significant make them a unique model organism for understanding fluid mixing. In this paper, 3D fluid-structure interaction simulations of a pulsing soft coral are used to quantify fluid transport and fluid mixing across a wide range of Re. The results show that net transport is negligible for $Re<10$, and continuous upward flow is produced for $Re\geq 10$.Comment: 8 pages, 8 figure

Phase-Retrieved Tomography enables imaging of a Tumor Spheroid in Mesoscopy Regime

Optical tomographic imaging of biological specimen bases its reliability on the combination of both accurate experimental measures and advanced computational techniques. In general, due to high scattering and absorption in most of the tissues, multi view geometries are required to reduce diffuse halo and blurring in the reconstructions. Scanning processes are used to acquire the data but they inevitably introduces perturbation, negating the assumption of aligned measures. Here we propose an innovative, registration free, imaging protocol implemented to image a human tumor spheroid at mesoscopic regime. The technique relies on the calculation of autocorrelation sinogram and object autocorrelation, finalizing the tomographic reconstruction via a three dimensional Gerchberg Saxton algorithm that retrieves the missing phase information. Our method is conceptually simple and focuses on single image acquisition, regardless of the specimen position in the camera plane. We demonstrate increased deep resolution abilities, not achievable with the current approaches, rendering the data alignment process obsolete.Comment: 21 pages, 5 figure

OP0205 ULTRASOUND-DETECTED CALCIUM PYROPHOSPHATE CRYSTAL DEPOSITION: WHICH SITES SHOULD BE SCANNED?

Background:In recent years, ultrasonography (US) has emerged as an accurate and reliable tool for the diagnosis of calcium pyrophosphate (CPP) deposition disease (CPPD) in daily practice. Previous studies analyzed the diagnostic value of US findings in different tissues and joints. However, no studies have investigated the optimal US scanning protocol in the diagnosis of CPPD at patient level.Objectives:To assess the diagnostic value of the combinations of OMERACT-defined US findings of CPPD in the upper and lower limbs and to select the best minimal combination of anatomic structures to be scanned for diagnosing CPPD in inter-critical periods.Methods:Patients with a crystal-proven diagnosis of CPPD and age- and sex-matched disease-controls were prospectively enrolled in this cross-sectional, monocentric, case-control study. All subjects underwent a bilateral US examination of 9 hyaline cartilages (HC), 6 fibrocartilages (FC), 5 tendons, 1 joint recess and 1 ligament as follows: shoulder (glenoid FC, humeral HC and acromioclavicular FC), elbow (humeral HC and triceps tendon), wrist (triangular FC, scapho-lunate ligament, volar recess of the radio-lunate joint), hand (HC of the metacarpophalangeal joints from 2nd to 5th finger), hip (acetabular FC and femoral HC), knee (femoral condyles' HC, meniscal FC, patellar and quadriceps tendons), ankle (talar HC, Achilles tendon and plantar fascia). US assessment was carried-out by a rheumatologist blinded to clinical data. CPP deposits were identified as presence/absence, according to the OMERACT definitions [1].Results:Ninety-five patients were enrolled: 45 CPPD patients (age: 72±10.6 years, disease duration: 5.6±7.8 years, female/male ratio: 1.3) and 50 age- and sex-matched disease-controls (18 with rheumatoid arthritis, 13 with osteoarthritis, 10 with psoriatic arthritis and 9 with gout).The FC of the medial and lateral meniscus were the most frequently involved targets of CPP deposits in cases (81.8% and 77.3% of patients, respectively), followed by the triangular FC of the wrist (68.2%), the HC of the femoral condyles (54.5%), the scapho-lunate ligament (52.3%) and the acetabular FC (50.0%). In all these anatomical targets, US findings indicative of CPP deposits were detected in a significantly higher percentage of cases than controls (p<0.01).The US scanning protocols that showed the best balance between sensitivity and specificity, the most sensitive and the most specific were shown in Table 1.Table 1.Diagnostic performances of different US scanning protocolsAnatomical targetsSESPLH+LH-Knee meniscal FC and wrist triangular FC0.86(0.76-0.96)0.86(0.73-0.94)6.35(3.17-12.72)0.13(0.06-0.30)Knee meniscal FC, wrist triangular FC and hip acetabular FC0.93(0.82-0.99)0.82(0.69-0.91)5.19(2.85-9.42)0.08(0.03-0.24)Hip acetabular FC, knee femoral condyles' HC andwrist scapho-lunate ligament0.67(0.51-0.80)0.96(0.86-0.99)16.67(4.22-65.82)0.35(0.23-0.53)LH: likelihood ratio, SE: sensitivity, SP: specificity, US: ultrasonography.In all US scanning protocols, each anatomical target was assessed bilaterally.Figure 1 includes representative pictures showing CPP crystal deposits in different anatomical targets.A: Wrist, longitudinal scan of the triangular FC complex.B: Knee, longitudinal scan of the lateral meniscus.C: Hip, longitudinal scan of the acetabular labrum FC,D: Knee, longitudinal scan of the medial femoral condyle's HC.Arrows: CPP crystal deposits at FC, arrowhead: CPP crystal deposits at HC.Conclusion:Our results suggest that bilateral US assessment of knee, wrist and hip provided acceptable sensitivity and specificity for diagnosing CPPD.References:[1]Filippou G, et al.

Debris Cloud Evolution: Mathematical Modeling and Application to Satellite Constellation Design

Orbital break-ups produce a large number of fragments, which constitute an obvious hazard for other satellites in nearby orbits. Of these fragments, many are too small to be detected by ground-based facilities: this leads to the need for mathematical modelling as a tool for adequate risk analysis. In this paper an average spatial density model is presented. It is based on the Gauss analogy and, for unperturbed Keplerian orbits, it matches the asymptotic density model developed by other authors. Risk analysis for satellite constellations is an interesting application of debris cloud evolution models: the survivability of a constellation as a whole following the break-up of one of its satellites is obviously of primary concern in the constellation design. Risk analysis is conducted over a number of traditional configurations in order to achieve an additional constraint on the design parameters. Results indicate the remarkable influence of the fragmentation point position along the orbit; moreover, the higher risk for low orbit and the advantage of placing more satellites on a limited number of planes are assessed

Simulation of 3d Ising spin glass model using three replicas: study of Binder cumulants

We have carried out numerical simulations of the three-dimensional Ising spin glass model with first neighbour Gaussian couplings using three replicas for each sample of couplings. We have paid special attention to the measure of two types of Binder cumulant that can be constructed from the three possible overlaps between the replicas. We obtain new information about the possible phase transition and perform an initial analysis of the ultrametricity issue.Comment: 14 pages and 7 figures, available at http://chimera.roma1.infn.it/index_papers_complex.htm

Maximizing the Total Resolution of Graphs

A major factor affecting the readability of a graph drawing is its resolution. In the graph drawing literature, the resolution of a drawing is either measured based on the angles formed by consecutive edges incident to a common node (angular resolution) or by the angles formed at edge crossings (crossing resolution). In this paper, we evaluate both by introducing the notion of "total resolution", that is, the minimum of the angular and crossing resolution. To the best of our knowledge, this is the first time where the problem of maximizing the total resolution of a drawing is studied. The main contribution of the paper consists of drawings of asymptotically optimal total resolution for complete graphs (circular drawings) and for complete bipartite graphs (2-layered drawings). In addition, we present and experimentally evaluate a force-directed based algorithm that constructs drawings of large total resolution

Random wave run-up with a physically-based Lagrangian shoreline model

n the present paper the run-up of random waves was calculated by means of a numerical method. In situ measurements based on a video imaging technique have been used for the validation of the present numerical model. The on-site run-up measurements have been carried out at Lido Signorino beach, near Marsala, Italy,along a transect, normal to the shore. A video camera and a linear array of rods have been used to obtain field data. Numerical simulations with a 1DH Boussinesq-type of model for breaking waves which takes into account the wave run-up by means of a Lagrangian shoreline model have been carried out. In such simulations random waves of given spectrum have been propagated in a numerical flume having the same beach slope of the measured transect. The comparison between registered and estimated run-up underlined an acceptable agreement. Indeed, the numerical model tends to underestimate the actual R2%, with the maximum underestimate being less than 24%, which is a reasonable error in many cases of engineering interest
