A Framework to Explain the Brazilian Soccer Championships Classifications

The sulphur emissive capability, on combustion, of coke which is formed during upgrading of sulphur-containing heavy crude oils, including oil sands bitumen, and residua, is decreased by the addition of calcium carbonate, preferably in the form of limestone, to the heavy crude oil prior to coking. The presence of the limestone leads to an increased yield of liquid distillates from the coking process under preferred coking conditions. Ash remaining after combustion of the coke may be leached to recover nickel and vanadium values therefrom.
Solving the Forward Kinematics of a Gough-Type Parallel Manipulator with Interval Analysis

We consider in this paper a Gough-type parallel robot and we present an efficient algorithm based on interval analysis that allows us to solve the forward kinematics, i.e., to determine all the possible poses of the platform for given joint coordinates. This algorithm is numerically robust as numerical round-off errors are taken into account; the provided solutions are either exact in the sense that it will be possible to refine them up to an arbitrary accuracy or they are flagged only as a “possible” solution as either the numerical accuracy of the computation does not allow us to guarantee them or the robot is in a singular configuration. It allows us to take into account physical and technological constraints on the robot (for example, limited motion of the passive joints). Another advantage is that, assuming realistic constraints on the velocity of the robot, it is competitive in term of computation time with a real-time algorithm such as the Newton scheme, while being safer.
Stereotype Threat Effects on Black and White Athletic Performance

Two experiments showed that framing an athletic task as diagnostic of negative racial stereotypes about Black or White athletes can impede their performance in sports. In Experiment 1, Black participants performed significantly worse than did control participants when performance on a golf task was framed as diagnostic of "sports intelligence. " In comparison, White participants performed worse than did control participants when the golf task was framed as diagnostic of "natural athletic ability. " Experiment 2 observed the effect of stereotype threat on the athletic performance of White participants for whom performance in sports represented a significant measure of their self-worth. The implications of the findings for the theory of stereotype threat (C. M. Steele, 1997) and for participation in sports are discussed.
Fast Matching of Planar Shapes in Sub-cubic Runtime

The matching of planar shapes can be cast as a problem of finding the shortest path through a graph spanned by the two shapes, where the nodes of the graph encode the local similarity of respective points on each contour. While this problem can be solved using dynamic time warping, the complete search over the initial correspondence leads to cubic runtime in the number of sample points. In this paper, we cast the shape matching problem as one of finding the shortest circular path on a torus. We propose an algorithm to determine this shortest cycle which has provably sub-cubic runtime. Numerical experiments demonstrate that the proposed algorithm provides faster shape matching than previous methods. As an application, we show that it allows to efficiently compute a clustering of a shape data base.

Proenzyme forms of prostate-specific antigen in serum improve the detection of prostate cancer.

INTRODUCTION Pro or precursor forms of prostate-specific antigen (PSA) have emerged as potentially important diagnostic serum markers for prostate cancer detection. Immunoassays were developed to measure specific proPSA forms containing propeptides of 2, 4, and 7 amino acids [(-2)proPSA, (-4)proPSA, and (-7)proPSA, respectively]. METHODS Research-use dual monoclonal antibody immunoassays using europium-labeled detection monoclonal antibodies were developed for each form of proPSA. Sera from patients with prostate cancer or benign prostate disease containing 4-10 microg/L PSA were assayed and analyzed by area under the ROC curve (AUC) for specificity and sensitivity. RESULTS The proPSA forms had quantification limits of 0.015-0.025 microg/L in serum, with cross-reactivities <1% with PSA. The sum of the proPSA forms divided by free PSA (percentage proPSA) had a higher AUC than did percentage of (-2)proPSA, free PSA, and complexed PSA with AUC (95% confidence intervals) of 0.69 (0.64-0.74), 0.64 (0.58-0.68), 0.63 (0.58-0.68), and 0.57 (0.51-0.62), respectively. The proPSA comprised a median of 33% of the free PSA in cancer and 25% in noncancer sera (P <0.0001). One-third (33%) of cancer samples had >40% proPSA, whereas only 8% of noncancer samples did (P <0.0001). In men with cancer and >25% free PSA, the (-2)proPSA had an AUC of 0.77 (0.66-0.86), with 90% sensitivity and 36% specificity at 0.04 microg/L. CONCLUSIONS The percentage of proPSA gave better cancer detection in the 4-10 microg/L range than did percentage of free PSA and complexed PSA. (-2)proPSA significantly discriminated cancer in men whose serum had >25% free PSA, for whom there is currently no good marker for cancer detection.
Donepezil Impairs Memory in Healthy Older Subjects: Behavioural, EEG and Simultaneous EEG/fMRI Biomarkers

Rising life expectancies coupled with an increasing awareness of age-related cognitive decline have led to the unwarranted use of psychopharmaceuticals, including acetylcholinesterase inhibitors (AChEIs), by significant numbers of healthy older individuals. This trend has developed despite very limited data regarding the effectiveness of such drugs on non-clinical groups and recent work indicates that AChEIs can have negative cognitive effects in healthy populations. For the first time, we use a combination of EEG and simultaneous EEG/fMRI to examine the effects of a commonly prescribed AChEI (donepezil) on cognition in healthy older participants. The short- and long-term impact of donepezil was assessed using two double-blind, placebo-controlled trials. In both cases, we utilised cognitive (paired associates learning (CPAL)) and electrophysiological measures (resting EEG power) that have demonstrated high-sensitivity to age-related cognitive decline. Experiment 1 tested the effects of 5 mg/per day dosage on cognitive and EEG markers at 6-hour, 2-week and 4-week follow-ups. In experiment 2, the same markers were further scrutinised using simultaneous EEG/fMRI after a single 5 mg dose. Experiment 1 found significant negative effects of donepezil on CPAL and resting Alpha and Beta band power. Experiment 2 replicated these results and found additional drug-related increases in the Delta band. EEG/fMRI analyses revealed that these oscillatory differences were associated with activity differences in the left hippocampus (Delta), right frontal-parietal network (Alpha), and default-mode network (Beta). We demonstrate the utility of simple cognitive and EEG measures in evaluating drug responses after acute and chronic donepezil administration. The presentation of previously established markers of age-related cognitive decline indicates that AChEIs can impair cognitive function in healthy older individuals. To our knowledge this is the first study to identify the precise neuroanatomical origins of EEG drug markers using simultaneous EEG/fMRI. The results of this study may be useful for evaluating novel drugs for cognitive enhancement.
Post-orogenic extension and metamorphic core complexes in a heterogeneous crust: the role of crustal layering inherited from collision. Application to the Cyclades (Aegean domain)

SUMMARY The development of metamorphic core complexes (MCC) corresponds to a mode of lithospheric continental stretching that follows collision. In most of the models that explain the formation of the MCC, high thermal gradients are necessary to weaken the lower crust and to induce its ascent. Such models fail to explain the exhumation of high pressure–low temperature metamorphic rocks in metamorphic core complex structures as observed in the Cycladic Blueschists in the Aegean domain. Besides, account for the lithological crustal stratification induced from collision has never been tested. In this paper, we use fully coupled thermomechanical modelling to investigate the impact of structural heritage and initial thermal gradient on the behaviour of the post-orogenic continental lithosphere. The models are designed and validated by petrological, structural and time data from the Cyclades. As a result, high thermal gradients (Moho temperature higher than 800 ◦ C) are neither necessary nor always sufficient to induce the development of a metamorphic core complex. At the contrary, the rheological layering of the crust inherited from collision is a first-order parameter controlling the development of extensional structures in post-orogenic settings. ‘Cold’ MCC can develop if the crust is made of a strong nappe thrust on top of weaker metamorphic cover and basement units, as observed in the Cyclades.
Diencephalic amnesia : rodent cognition, neural markers and electrophysiology.

The anterior thalamic nuclei (ATN), mammillary bodies and their interconnecting fibre tract the mammillothalamic tract (MTT) are important components of an extended hippocampal circuit for episodic memory. In humans, damage to the MTT or ATN from stroke, alcohol abuse, developmental brain injury and neurodegeneration is associated with severe anterograde amnesia. However, uncertainty regarding lesion boundaries and influence of pathology elsewhere in clinical settings limits firm conclusions regarding the specific contributions of the MTT and ATN to memory. These two structures are often considered to be functionally equivalent, but a direct comparison of ATN and MTT lesions in rats in Experiment 1 found that only ATN lesions impaired spatial reference memory and produced more severe deficits than MTT lesions on spatial working memory tasks in the radial-arm maze (RAM). ATN lesions also reduced zif268 expression to a greater degree in the retrosplenial cortex and hippocampal CA1 than MTT lesions. However, MTT and to a lesser extent, ATN lesions reduced NeuN cell counts in all three regions of the MB, so the relative impact of these lesions is not explained by MB pathology. Rather the greater ATN lesions deficits found here likely reflect disruption to additional processes associated with dense connections of the ATN with both hippocampal and cortical sites. In a previous study, an unexpected discrepancy between ATN and MB lesions was found on an object-place pairedassociate task. This anomalous finding was examined and resolved in Experiment 2. Rats with MTT lesions had impaired acquisition of object-place associations in which probe tests revealed that they were likely to be responding on the basis of location, not direction or egocentric information. Experiment 3 provided highly novel evidence that MTT lesions can disrupt rhythmic oscillatory interactions at theta frequency (4-12Hz) between the ATN-PFC, ATN-HPC and HPC-PFC while rats make spatial memory choices in the RAM. It would therefore be expected that ATN lesions may even more profoundly impair oscillatory activity within the circuit. These findings provide critical insight into two different perspectives regarding the association between diencephalic pathology and amnesia. Specifically, it appears that other direct and indirect cortical and hippocampal inputs of the ATN make it a relatively more critical point of dysfunction than would be expected by a primary focus on the albeit important VTg, MB and MTT brainstem inputs to the extended memory system.

Query-Adaptive Logo Search using Shape-Aware Descriptors

We propose a graph-based optimization framework to leverage category independent object proposals (candidate object regions) for logo search in a large scale image database. The proposed contour-based feature descriptor EdgeBoW is robust to view-angle changes, varying illumination conditions and can implicitly capture the significant object shape information. Having been equipped with a local descriptor, it can handle a fair amount of occlusion and deformation frequently present in a real-life scenario. Given a small set of initially retrieved candidate object proposals, a fast graph-based short-listing scheme is designed to exploit the mutual similarities among these proposals for eliminating outliers. In contrast to a coarse image-level pairwise similarity measure, this search focussed on a few specific image regions provides a more accurate method for matching. The proposed query expansion strategy aims to assess each of the remaining better matched proposals against all its neighbors within the same image for a precise localization. Combined with an efficient feature descriptor EdgeBoW, a set of more insightful edge-weights and node-utility measures can yield promising results, specially for object categories primarily defined by its shape. Extensive set of experiments performed on a number of benchmark datasets demonstrates its effectiveness and superior generalization ability in both clutter intensive real-life images and poor quality binary document images.
Quantifying the effect of turbulent magnetic diffusion on the growth rate of the magneto−rotational instability

Context. In astrophysics, turbulent diffusion is often used in place of microphysical diffusion to avoid resolving the small scales. However, we expect this approach to break down when time and length scales of the turbulence become comparable with other relevant time and length scales in the system. Turbulent diffusion has previously been applied to the magneto-rotational instability (MRI), but no quantitative comparison of growth rates at different turbulent intensities has been performed. Aims. We investigate to what extent turbulent diffusion can be used to model the effects of small-scale turbulence on the kinematic growth rates of the MRI, and how this depends on angular velocity and magnetic field strength. Methods. We use direct numerical simulations in three-dimensional shearing boxes with periodic boundary conditions in the spanwise direction and additional random plane-wave volume forcing to drive a turbulent flow at a given length scale. We estimate the turbulent diffusivity using a mixing length formula and compare with results obtained with the test-field method. Results. It turns out that the concept of turbulent diffusion is remarkably accurate in describing the effect of turbulence on the growth rate of the MRI. No noticeable breakdown of turbulent diffusion has been found, even when time and length scales of the turbulence become comparable with those imposed by the MRI itself. On the other hand, quenching of turbulent magnetic diffusivity by the magnetic field is found to be absent. Conclusions. Turbulence reduces the growth rate of the MRI in the same way as microphysical magnetic diffusion does.
Cloudlet network design optimization

Major interest is currently given to the integration of clusters of virtualization servers, also referred to as `cloudlets', into the access network to allow higher performance and reliability in the access to mobile cloud services. We tackle the cloudlet network design problem for mobile access networks. The model is such that virtual machines are associated with mobile users and are allocated to cloudlets. Designing a cloudlet network implies first determining where to install cloudlet facilities among the available sites, then assigning sets of access points such as base-stations to cloudlets, while supporting virtual machine migrations and taking into account partial user mobility information, as well as the satisfaction of service-level agreements. We present link-path formulations supported by heuristics to compute solutions in reasonable time. We qualify the advantage in considering mobility for both users and virtual machines as up to 40% less cloudlet facilities to install and 40% less virtual machine migrations to execute. We compare two migration modes, bulk and live migration, as a function of mobile cloud service requirements, determining that a high preference should be given to bulk migrations for delay-stringent services such as augmented reality support, while for applications with less stringent delay requirements, live migration appears as largely preferable.
Cell cycle diversity involves differential regulation of Cyclin E activity in the Drosophila bristle cell lineage

In the Drosophila bristle lineage, five differentiated cells arise from a precursor cell after a rapid sequence of asymmetric cell divisions (one every 2 hours). We show that, in mitotic cells, this rapid cadence of cell divisions is associated with cell cycles essentially devoid of the G1-phase. This feature is due to the expression of Cyclin E that precedes each cell division, and the differential expression of the S-transition negative regulator, Dacapo. Thus, apart from endocycles (G/S), which occurred in two out of five terminal cells, two other cell cycles coexist in this lineage: (1) an atypical cell cycle (S/G2/M), in which the S-phase is initiated during the preceding telophase; and (2) a canonical cell cycle (G1/S/G2/M) with a brief G1 phase. These two types of cell cycle result from either the absence or very transient expression of Dap, respectively. Finally, we show that the fate determinant factor, Tramtrack, downregulates Cyclin E expression and is probably involved in the exit of the cells from the cell cycle.
Prevalence and complications of uveitis in juvenile idiopathic arthritis in a population-based nation-wide study in Germany: suggested modification of the current screening guidelines.

OBJECTIVES To analyse the prevalence and complications of uveitis and their predictors in a large cohort of patients with juvenile idiopathic arthritis (JIA). METHODS Data of 3271 JIA patients as classified by International League of Associations for Rheumatology (ILAR) criteria included in a national database during 1 yr were analysed. RESULTS Uveitis prevalence was 12% of all JIA patients. The most frequent were oligoarthritis extended (25%) and persistent (16%). JIA patients with uveitis were significantly younger at onset of arthritis (3.8 vs 7.0 yrs) or ANA-positive (86% vs 42%) than the patients without uveitis. Predictors of uveitis included age at onset (P= 0.03) and ANA-positivity (P< 0.01) besides the presence of a certain JIA subgroup (P= 0.04). Uveitis was clinically silent in 75% of the oligoarthritis but in none of the enthesitis-related arthritis patients. The median onset of uveitis was 5.5 months after arthritis manifestation. In 73%, 77% and 90%, uveitis developed within 1, 2 and 4 yrs after arthritis, respectively. Anterior uveitis was the most common anatomic type of uveitis (83%). Uveitis complications at mean follow-up of 5.6 yrs were common (56%), and predictors for complications included presence of complications at first visit (P< 0.001) and uveitis manifestation before arthritis (P= 0.001), but not ANA positivity. CONCLUSIONS The JIA subgroups markedly differ with respect to the prevalence and course of associated uveitis. Ophthalmological screening should be initiated early after arthritis onset and the intervals be related to the JIA subgroup. A modification of the current screening guidelines is suggested.
The Effect of Noseband Tightening on Horses’ Behavior, Eye Temperature, and Cardiac Responses

Restrictive nosebands are common in equestrian sport. This is concerning, as recent evidence suggests that very tight nosebands can cause a physiological stress response, and may compromise welfare. The objective of the current study was to investigate relationships that noseband tightness has with oral behavior and with physiological changes that indicate a stress response, such as increases in eye temperature (measured with infrared thermography) and heart rate and decreases in heart rate variability (HRV). Horses (n = 12) wearing a double bridle and crank noseband, as is common in dressage at elite levels, were randomly assigned to four treatments: unfastened noseband (UN), conventional area under noseband (CAUN) with two fingers of space available under the noseband, half conventional area under noseband (HCAUN) with one finger of space under the noseband, and no area under the noseband (NAUN). During the tightest treatment (NAUN), horse heart rate increased (P = 0.003), HRV decreased (P < 0.001), and eye temperature increased (P = 0.011) compared with baseline readings, indicating a physiological stress response. The behavioral results suggest some effects from bits alone but the chief findings are the physiological readings that reflect responses to the nosebands at their tightest. Chewing decreased during the HCAUN (P < 0.001) and NAUN (P < 0.001) treatments. Yawning rates were negligible in all treatments. Similarly, licking was eliminated by the NAUN treatment. Following the removal of the noseband and double bridle during the recovery session, yawning (P = 0.015), swallowing (P = 0.003), and licking (P < 0.001) significantly increased compared with baseline, indicating a post-inhibitory rebound response. This suggests a rise in motivation to perform these behaviors and implies that their inhibition may place horses in a state of deprivation. It is evident that a very tight noseband can cause physiological stress responses and inhibit the expression of oral behaviors.
The Risky Path to a Followership Identity: From Abstract Concept to Situated Reality

Followership research has increased recently, but little attention has been paid to the complexities and challenges of creating a followership identity. Researchers typically portray followership as a safe alternative to leadership identity, but we challenge this assumption by using naturally occurring workplace interactions to identify active contributions as well as risks associated with a follower identity. In this study, we use conversation analysis to examine how people collaboratively construct identities, and how identity development shapes and organizes interactions between people. The findings reveal the risks of misidentifying the task at hand, of being too authoritative, and of claiming too much knowledge. Also, our analyses highlight that leader and follower roles remain abstract in workplace interactions and, instead, people focus more on negotiated, task-oriented, practical identities.
