Tracking Influential Individuals in Dynamic Networks

In this paper, we tackle a challenging problem inherent in a series of applications: tracking the influential nodes in dynamic networks. Specifically, we model a dynamic network as a stream of edge weight updates. This general model embraces many practical scenarios as special cases, such as edge and node insertions, deletions as well as evolving weighted graphs. Under the popularly adopted linear threshold model and independent cascade model, we consider two essential versions of the problem: finding the nodes whose influences passing a user specified threshold and finding the top-<inline-formula><tex-math notation="LaTeX">$k$</tex-math><alternatives> <inline-graphic xlink:href="yang-ieq1-2734667.gif"/></alternatives></inline-formula> most influential nodes. Our key idea is to use the polling-based methods and maintain a sample of random RR sets so that we can approximate the influence of nodes with provable quality guarantees. We develop an efficient algorithm that incrementally updates the sample random RR sets against network changes. We also design methods to determine the proper sample sizes for the two versions of the problem so that we can provide strong quality guarantees and, at the same time, be efficient in both space and time. In addition to the thorough theoretical results, our experimental results on five real network data sets clearly demonstrate the effectiveness and efficiency of our algorithms.
Neuronal Synchronization Can Control the Energy Efficiency of Inter-Spike Interval Coding

The role of synchronous firing in sensory coding and cognition remains controversial. While studies, focusing on its mechanistic consequences in attentional tasks, suggest that synchronization dynamically boosts sensory processing, others failed to find significant synchronization levels in such tasks. We attempt to understand both lines of evidence within a coherent theoretical framework. We conceptualize synchronization as an independent control parameter to study how the postsynaptic neuron transmits the average firing activity of a presynaptic population, in the presence of synchronization. We apply the Berger-Levy theory of energy efficient information transmission to interpret simulations of a Hodgkin-Huxley-type postsynaptic neuron model, where we varied the firing rate and synchronization level in the presynaptic population independently. We find that for a fixed presynaptic firing rate the simulated postsynaptic interspike interval distribution depends on the synchronization level and is well-described by a generalized extreme value distribution. For synchronization levels of 15% to 50%, we find that the optimal distribution of presynaptic firing rate, maximizing the mutual information per unit cost, is maximized at ~30% synchronization level. These results suggest that the statistics and energy efficiency of neuronal communication channels, through which the input rate is communicated, can be dynamically adapted by the synchronization level.
Using Task-Induced Pupil Diameter and Blink Rate to Infer Cognitive Load

Minimizing user cognitive load is suggested as an integral part of human-centered design, where a more intuitive, easy to learn, and adaptive interface is desired. In this context, it is difficult to develop optimal strategies to improve the design without first knowing how user cognitive load fluctuates during interaction. In this study, we investigate how cognitive load measurement is affected by different task types from the perspective of the load theory of attention, using pupil diameter and blink measures. We induced five levels of cognitive load during low and high perceptual load tasks and found that although pupil diameter showed significant effects on cognitive load when the perceptual load was low, neither blink rate nor pupil diameter showed significant effects on cognitive load when the perceptual load was high. The results indicate that pupil diameter can index cognitive load only in the situation of low perceptual load and are the first to provide empirical support for the cognitive control aspect of the load theory of attention, in the context of cognitive load measurement. Meanwhile, blink is a better indicator of perceptual load than cognitive load. This study also implies that perceptual load should be considered in cognitive load measurement using pupil diameter and blink measures. Automatic detection of the type and level of load in this manner helps pave the way for better reasoning about user internal processes for human-centered interface design.

FactorsR: An RWizard Application for Identifying the Most Likely Causal Factors in Controlling Species Richness

We herein present FactorsR, an RWizard application which provides tools for the identification of the most likely causal factors significantly correlated with species richness, and for depicting on a map the species richness predicted by a Support Vector Machine (SVM) model. As a demonstration of FactorsR, we used an assessment using a database incorporating all species of terrestrial carnivores, a total of 249 species, distributed across 12 families. The model performed with SVM explained 91.9% of the variance observed in the species richness of terrestrial carnivores. Species richness was higher in areas with both higher vegetation index and patch index, i.e., containing higher numbers of species whose range distribution is less fragmented. Lower species richness than expected was observed in Chile, Madagascar, Sumatra, Taiwan, and Sulawesi.
Minimum Rényi and Wehrl entropies at the output of bosonic channels

The minimum Renyi and Wehrl output entropies are found for bosonic channels in which the signal photons are either randomly displaced by a Gaussian distribution (classical-noise channel), or coupled to a thermal environment through lossy propagation (thermal-noise channel). It is shown that the Renyi output entropies of integer orders z{>=}2 and the Wehrl output entropy are minimized when the channel input is a coherent state.
“Behind the Curtain”: Strip Clubs and the Management of Competition for Tips

Ethnographers have amassed a large body of literature on exotic dance and strip clubs. However, this literature contains little information about strip club managers and the work they perform “behind the curtain. ” This article draws on participant observation in strip clubs and semistructured interviews with managers of strip clubs to explore how managers must work to mitigate the consequences of a payment and staffing structure that exacerbates competition between dancers for tips. Managers are keenly aware of the negative effects of competition between dancers, and they employ motivational tactics to manage the dancers through economic precarity, such as normalizing uncertainty, encouraging self-blame, and using “teamwork” discourses to inculcate a sense of solidarity among dancers and to diffuse the competitive environment in strip clubs. This article reveals how managers strive to normalize and legitimate the precarious work of exotic dancing, contributing to the literatures on exotic dance and tipped employment.
A polymorphism of the interleukin-1 β gene influences survival in pancreatic cancer

Pro-inflammatory cytokines contribute to the cachexia associated with pancreatic cancer and stimulate the acute phase response which has been associated with shortened survival in such patients. Polymorphisms of cytokine genes may influence their production. The present study examined the effect of a polymorphism of the interleukin (IL)-1b gene upon the inflammatory state and survival in pancreatic cancer. Genomic DNA was obtained from 64 patients with pancreatic cancer and 101 healthy controls. Using the polymerase chain reaction and subsequent TaqI restriction enzyme digestion the subject’s genotype for a diallelic polymorphism of the interleukin-1b gene was established. IL-1b production by peripheral blood mononuclear cells and serum C-reactive protein (CRP) levels from patients were also examined and survival noted. Patients homozygous for allele 2 of the IL-1b gene had significantly shorter survival than other groups (P = 0.0001). These patients also exhibited higher IL-1b production (P = 0.022). Possession of allele 2 was also associated with significantly shorter survival (median 144 vs 256 days, P = 0.034) and significantly higher CRP level (P = 0.0003). The possession of a genotype resulting in increased IL-1b production was associated with shortened survival and increased serum CRP level. This may reflect the role of IL-1b in inducing an acute phase protein response and cachexia in cancer or may be related to changes in tumour phenotye. © 2000 Cancer Research Campaign http://www.bjcancer. com
Insulin-Like Growth Factor 2 mRNA-Binding Protein 3 is a Novel Post-Transcriptional Regulator of Ewing Sarcoma Malignancy

Purpose: Large-scale sequencing studies have indicated that besides genomic alterations, the posttranscriptional regulation of gene expression or epigenetic mechanisms largely influences the clinical behavior of Ewing sarcoma. We investigated the significance of the RNA-binding protein IGF2BP3 in the regulation of Ewing sarcoma aggressiveness. Experimental Design: Explorative study was performed in 14 patients with localized Ewing sarcoma using RNA sequencing. Next, 128 patients with localized Ewing sarcoma were divided into two cohorts. In the training set, 29 Ewing sarcoma samples were analyzed using Affymetrix GeneChip arrays. In the validation set, 99 Ewing sarcoma samples were examined using qRT-PCR. Patient-derived cell lines and experimental models were used for functional studies. Results:Univariate and multivariate analyses indicated IGF2BP3 as a potent indicator of poor prognosis. Furthermore, ABCF1 mRNA was identified as a novel partner of IGF2BP3. Functional studies indicated IGF2BP3 as an oncogenic driver and ABCF1 mRNA as a sponge that by binding IGF2BP3, partly repressed its functions. The combined evaluation of IGF2BP3 and ABCF1 could identify different patient outcomes—high IGF2BP3 and low ABCF1 levels indicated poor survival (25%), whereas low IGF2BP3 and high ABCF1 levels indicated favorable survival (85.5%). The bromodomain and extraterminal domain inhibitor (BETi) JQ1 decreased IGF2BP3 expression, modified the expression of its validated targets and inhibited the capability of Ewing sarcoma cells to grow under anchorage-independent conditions. Conclusions: The combined assessment of IGF2BP3 and ABCF1 predicts recurrence in Ewing sarcoma patients. Thus, for patients with high expression of IGF2BP3 and poor probability of survival, the use of BETis should be clinically evaluated. Clin Cancer Res; 24(15); 3704–16. ©2018 AACR.
Persistent Scatterer InSAR for Crustal Deformation Analysis , with Application to Volcán Alcedo , Galápagos

While conventional interferometric synthetic aperture radar (InSAR) is a very effective technique for measuring crustal deformation, almost any interferogram includes large areas where the signals decorrelate and no measurement is possible. Persistent scatterer (PS) InSAR overcomes the decorrelation problem by identifying resolution elements whose echo is dominated by a single scatterer in a series of interferograms. Existing PS methods have been very successful in analysis of urban areas, where stable angular structures produce efficient reflectors that dominate background scattering. However, man-made structures are absent from most of the Earth’s surface. Furthermore, existing methods identify PS pixels based on the similarity of their phase history to an assumed model for how deformation varies with time, whereas characterizing the temporal pattern of deformation is commonly one of the aims of any deformation study. We describe here a method for PS analysis, StaMPS, that uses spatial correlation of interferogram phase to find pixels with low phase variance in all terrains, with or without buildings. Prior knowledge of temporal variations in the deformation rate is not required for their identification. We apply StaMPS to Volcán Alcedo, where conventional InSAR fails, due to dense vegetation on the upper volcano flanks that causes most pixels to decorrelate with time. We detect two sources of deformation. The first we model as a contracting pipe-like body, which we interpret to be a crystallizing magma chamber. The second is downward and lateral motion on the inner slopes of the caldera, which we interpret as landsliding.
Value Investing in Thailand: Evidence from the Use of PEG

Value investing has gained popularity as a number of researches showed that various investment strategies based on this concept could generate significantly higher returns than the market. Investment using PEG as a selection rule was developed from the strategy based on P/E ratio. A test was conducted in this study to evaluate whether the investment strategy based on PEG ratio could be applied to the investments in the Stock Exchange of Thailand. Using the data from 1999-2010, the results showed that PEG ratio was effective in generating higher returns than the stock exchange’s total return index throughout the analysis of 12-year research data.
Future professionals’ perceptions of play and intended practices: the moderating role of efficacy beliefs

ABSTRACT This study examined whether perceptions of play of future professionals (N = 337) are related to their intent to integrate play into their practices and how their efficacy beliefs moderate the relation between perceptions of play and intended practices. While students with child-related majors were more likely to have stronger perceptions of play, they did not necessarily hold stronger intentions to use play in their practices, thus suggesting a noteworthy discrepancy between their perceptions and intentions. Students’ efficacy beliefs moderate the relationship between perceptions of play and their intended practices; however, an intriguing pattern was observed between high- and low-efficacy holders. The notable difference between participants with high- and low-efficacy beliefs in their intentions suggests the importance of efficacy beliefs in future professionals’ intended practices, as they make instructional and professional decisions in a challenging educational environment. The efficacy beliefs of future professionals need to be more seriously considered.
Finite element study of the vibroacoustic response of a structure , excited by a turbulent boundary layer

ABSTRACT The vibration and the acoustic field generated by a structure submerged in fluid, under a turbulent boundary layer flow is investigated. This investigation aims at improving numerical models predicting the radiated noise. Experimental results are compared to a finite element modelization. Modal behaviour of the FSI problem is described through a modal analysis based on the (U,p,φ) formulation with CODE_ASTER. The pressure field is computed as a sum of plane waves and harmonical analysis are performed for each term of the sum. Spectrum models are used to include the spatial correlation in the sum. The studied structure is a plate over a cavity, clamped on the leading edge and with other edges free. The apparatus is immerged in an hydrodynamic tunnel, a turbulent flow is generated on it’s upper side and the cavity is filled with fluid at rest. The vibroacoustic behaviour is mesured with a laser doppler scanning vibrometer and an acoustic transducer in the cavity. The validity of the model is assed by comparing numerical and experimental data for different spectrum models. A good reproduction of the behaviour of the plate is obtained in terms of defflection shapes and spectral levels.
Zilpaterol Hydrochloride affects Cellular Muscle Metabolism and Lipid Components of 10 Different Muscles in Feedlot Heifers

This study determined if zilpaterol hydrochloride (ZH) altered muscle metabolism and lipid components of 10 muscles. Crossbred heifers were either supplemented with ZH (n = 9) or not (Control; n = 10). Muscle tissue was collected (adductor femoris, biceps femoris, gluteus medius, infraspinatus, latissimus dorsi, longissimus dorsi, pectoralis profundi, semitendinosus, subscapularis, trapezius) immediately following carcass splitting. The mRNA abundance of AMPkɑ, IGF-I, MHC-I, IIA and IIX, β1-adrenergic receptor (βAR) and β2AR was determined, as well as, cross-sectional area and proportion of myosin isoforms, β1AR, β2AR, β3AR, nuclei, and satellite cell density. Furthermore, neutral (NL) and polar lipid (PL) fatty acids (FA) were quantified (mg/g). Zilpaterol hydrochloride decreased MHC-IIA mRNA (P = 0.007). In addition, ZH decreased total nuclei and β1AR and increased MHC-IIX cross-sectional area (P ≤ 0.021). Quantity of NL FA were not affected by ZH (P ≥ 0.173). However, among PL FA the ratio of PUFA:SFA was greater with ZH (P = 0.048). Muscle type impacted mRNA concentration of AMPkɑ, IGF-I, MHC-I, IIA, IIX, and β1AR mRNA concentration (P ≤ 0.037). Furthermore, the fiber type proportion, fiber cross-sectional area, and the densities of nuclei, β1AR, β2AR, β3AR, and satellite cells were influenced by muscle type (P ≤ 0.030). Total NL FA were affected by muscle (P ≤ 0.046). Meanwhile, total PL FA did not differ due to muscle (P = 0.242). However, prominent PL FA,18:0, 18:1 trans, and 18:2 n-6 were each greater (P < 0.05) among the oxidative subscapularis compared with glycolytic semitendinosus and adductor femoris. Overall, these data reveal that ZH impacts muscle metabolism and myogenic activity that establishes protein deposition. Meanwhile, ZH did not alter triglyceride content (NL), but cell membrane saturation (PL) was influenced, in accordance with alterations to muscle fiber type. Muscle also influenced muscle fiber type and lipid components. Therefore, muscle biology is greatly influenced by muscle but also through dietary inclusion of ZH.
Crystal Structures of Human Pyridoxal Kinase in Complex with the Neurotoxins, Ginkgotoxin and Theophylline: Insights into Pyridoxal Kinase Inhibition

Several drugs and natural compounds are known to be highly neurotoxic, triggering epileptic convulsions or seizures, and causing headaches, agitations, as well as other neuronal symptoms. The neurotoxic effects of some of these compounds, including theophylline and ginkgotoxin, have been traced to their inhibitory activity against human pyridoxal kinase (hPL kinase), resulting in deficiency of the active cofactor form of vitamin B6, pyridoxal 5′-phosphate (PLP). Pyridoxal (PL), an inactive form of vitamin B6 is converted to PLP by PL kinase. PLP is the B6 vitamer required as a cofactor for over 160 enzymatic activities essential in primary and secondary metabolism. We have performed structural and kinetic studies on hPL kinase with several potential inhibitors, including ginkgotoxin and theophylline. The structural studies show ginkgotoxin and theophylline bound at the substrate site, and are involved in similar protein interactions as the natural substrate, PL. Interestingly, the phosphorylated product of ginkgotoxin is also observed bound at the active site. This work provides insights into the molecular basis of hPL kinase inhibition and may provide a working hypothesis to quickly screen or identify neurotoxic drugs as potential hPL kinase inhibitors. Such adverse effects may be prevented by administration of an appropriate form of vitamin B6, or provide clues of how to modify these drugs to help reduce their hPL kinase inhibitory effects.
Changes in the World Distribution of Output Per Worker, 19601998: How a Standard Decomposition Tells an Unorthodox Story

Why have some countries done so much better than others over the recent past? This paper sheds light on this issue by providing a decomposition of the change in the distribution of output per worker across countries over the period 19601998. We find that most of the change in shape of the world distribution of income can be accounted for by a very substantial increase in the social returns to capital accumulation. In contrast, we do not find significant effects coming through changes in the effect of initial conditions or through increases in the importance of education.
STAR FORMATION LAWS IN BOTH GALACTIC MASSIVE CLUMPS AND EXTERNAL GALAXIES: EXTENSIVE STUDY WITH DUST CONINUUM, HCN (4-3), AND CS (7-6)

We observed 146 Galactic clumps in HCN (4-3) and CS (7-6) with the Atacama Submillimeter Telescope Experiment 10 m telescope. A tight linear relationship between star formation rate and gas mass traced by dust continuum emission was found for both Galactic clumps and the high redshift (z > 1) star forming galaxies (SFGs), indicating a constant gas depletion time of ∼100 Myr for molecular gas in both Galactic clumps and high z SFGs. However, low z galaxies do not follow this relation and seem to have a longer global gas depletion time. The correlations between total infrared luminosities (LTIR) and molecular line luminosities of HCN (4-3) and CS (7-6) are tight and sublinear extending down to clumps with LTIR ∼ 103 L☉. These correlations become linear when extended to external galaxies. A bimodal behavior in the LTIR– correlations was found for clumps with different dust temperature, luminosity-to-mass ratio, and σline/σvir. Such bimodal behavior may be due to evolutionary effects. The slopes of LTIR–L′mol correlations become more shallow as clumps evolve. We compared our results with lower J transition lines in Wu et al. (2010). The correlations between clump masses and line luminosities are close to linear for low effective excitation density tracers but become sublinear for high effective excitation density tracers for clumps with LTIR larger than LTIR ∼ 104.5 L☉. High effective excitation density tracers cannot linearly trace the total clump masses, leading to a sublinear correlations for both Mclump–L′mol and LTIR–L′mol relations.
Economic Integration, Cultural Standardization, and the Politics of Social Insurance

We explore cultural aspects of globalization and provide a model to illuminate some possible effects of globalization on the politics of redistribution within nations. The argument of the paper is as follows. Globalization is an extension of nationalism (not its antithesis) with regard to some aspects of culture and economic structure: it promotes cultural standardization and economic integration across national boundaries. But unlike nationalism, globalization does this without providing either the international cultural solidarity or governmental institutions capable of supporting egalitarian redistribution and insurance on a global scale, while weakening the nationbased institutions for the same. In this respect a globalized world may recreate the social structure of the archetypal agrarian empire: a dominant English-speaking class of cosmopolitans presiding over a heterogeneous and provincial underclass with little solidarity across the language groups and weak nationally-based instruments of social insurance and egalitarian redistribution. The politics of social insurance may thus increasingly pit the cosmopolitans against the provincials (not capital against labor, or even the high earners against the low earners, as many of the cosmopolitans are far from rich.) The result need not be institutional convergence to a world of uniformly minimalist welfare states, however, for the process of specialization induced by greater integration may support distinct institutional arrangements appropriate to each economy’s divergent product mixes. Countries specializing in goods characterized by volatile demand or requiring high levels of specific skills may be induced by globalization to strengthen their systems of social protection.
