Demineralization of Enamel in Primary Second Molars Related to Properties of the Enamel

Enamel structure is of importance in demineralization. Differences in porosity in enamel effect the rate of demineralization, seen between permanent and deciduous teeth. Individual differences have been shown in the mean mineral concentration values in enamel, the role of this in demineralization is not thoroughly investigated. The aim of this study was to study variations of depths of artificial lesions of demineralization and to analyze the depth in relation to variations in the chemical and mineral composition of the enamel. A demineralized lesion was created in second primary molars from 18 individuals. Depths of lesions were then related to individual chemical content of the enamel. Enamel responded to demineralization with different lesion depths and this was correlated to the chemical composition. The carbon content in sound enamel was shown to be higher where lesions developed deeper. The lesion was deeper when the degree of porosity of the enamel was higher.
Federal Reserve Bank of Dallas Globalization and Monetary Policy Institute Export Shocks and the Zero Bound Trap

When a small open economy experiences a sufficiently large negative export shock, it is vulnerable to falling into a zero bound trap. In addition, such a shock can have very large impact on the economy compared to the case when the zero bound is not a binding constraint. This could be one possible explanation as to why a country like Japan experienced much larger drop in output than the United States during the recent financial crisis. The author thanks Larry Christiano for sharing the analytical tools used in this paper and insightful discussions, especially at the onset of this research project. Thanks also go to Lena Körber and Maury Obstfeld for discussions and comments.

An Alternative Point Process Framework for Modeling Multivariate Extreme Values

An alternative limiting point process to that of de Haan (1985) is studied that holds regardless of whether the underlying data generation mechanism is asymptotically dependent or asymptotically independent. We characterize its intensity function in terms of the coefficient of tail dependence and an angular measure which satisfies a normalisation condition. We use this point process to derive a generalisation of standard componentwise maxima results that holds for both asymptotic dependence and asymptotic independence. We illustrate our results using a flexible parametric example and provide methods for simulating from both the limiting point process and the limiting componentwise maxima distribution.
Finite Galois covers, cohomology jump loci, formality properties, and multinets

We explore the relation between cohomology jump loci in a finite Galois cover, formality properties and algebraic monodromy action. We show that the jump loci of the base and total space are essentially the same, provided the base space is 1-formal and the monodromy action in degree 1 is trivial. We use reduced multinet structures on line arrangements to construct components of the first characteristic variety of the Milnor fiber in degree 1, and to prove that the monodromy action is non-trivial in degree 1. For an arbitrary line arrangement, we prove that the triviality of the monodromy in degree 1 can be detected in a precise way, by resonance varieties.
Solar Models: Influence of Equation of State and Opacity

Solar models through evolutionary phases of gravitational contraction, pre-main sequence and MS phases, up to current age 4.5E9 yr. and 4.57E9 yr. , were studied adopting different prescriptions for the equation of state (EOS) and different opacity tables. The results are compared with solar models we computed with different radiative opacities (Cox & Stewart 1970) and different EOS, as with models computed by other authors. Finally we provide the internal run of the thermodynamic quantities of our preferred solar model which possesses the following characteristics: age 4.50E9 yr. , initial He abundance by mass 0.285, parameter of the mixing length alpha=1.82, radius and temperature at the bottom of the convective envelope are R(bottom)=0.724 Rsun and T(bottom)=2.14E6 K, respectively.
Intersection numbers on the compact variety of rational ruled surfaces

We describe a natural action on the Quot scheme, Rd compactifying the space of degree d maps from P to the Grassmannian of lines. We identify the fixed points components for this action and the weights of the normal bundle of these components. We compute the degree of this Quot scheme under the generalized Plücker embedding by applying Atiyah-Bott localization formula.
TLR3 Sensing of Viral Infection

Viral infection is detected by the innate immune system which mounts a rapid semi-selective defence involving inflammation and production of type 1 interferons. Several sensors, both cell surface and intracellular, exist to detect different types of viral motifs. Double-stranded RNA viruses and dsRNA replication intermediates are detected by toll- like receptor 3 (TLR3) as well as by retinoid-inducible gene 1 (RIG-I) like receptors. Binding of dsRNA or its synthetic analogue poly I:C to TLR3 recruits the adaptor protein TRIF and stimulates distinct pathways leading to activation of interferon regulatory factor (IRF) and NF-￻ B. Here, we review the signalling cascades initiated by TLR3 and the modulation of these pathways.
Innovative approaches to continuous professional development (CPD) in early childhood education and care (ECEC) in Europe: findings from a comparative review

This article explores innovation as an aspect of in-service continuous professional development (CPD) in ECEC. Based on a literature review and a cross-country analysis conducted in ten European countries, we found that innovation in CPD was understood as a way to improving quality in ECEC. CPD no longer solely deals with practitioners' knowledge and skills. Rather, it encompasses processes such as critical thinking, reflexivity and co-creation within and across ECEC systems. Two overall approaches to innovation in CPD emerged: one can be characterised as developing in systems that lack a national definition for innovation, where there is nevertheless a growing awareness of the need to finding new solutions for ECEC; and one as highly innovative in systems that have a history, culture and societal tradition of innovation. Also, three additional insights were identified as crucial aspects of CPD in terms of innovation: (a) critical reflection; (b) communities of practice; and (c) a growing focus on politics that address social inequality through ECEC. This analysis contributes to filling the gaps in research on innovative CPD in ECEC at three levels: system (macro), inter-organisational (meso) and individual, organisational (micro). Further research is needed to explore more in-depth the identified approaches to innovation related to CPD and their impact on quality development in European ECEC.
A Comparative Study of Color Stability and Fluoride Release from Glass Ionomer Cements Combined with Chlorhexidine

ABSTRACT Background: Restoring carious teeth is one of the major treatment needs of young children. Glass ionomer cement (GIC) systems had become the most important dental restorative and luting materials for use in preschoolers, children and teenagers. Several attempts in developing GIC with antibacterial effects by addition of bactericides, such as chlorhexidine, have been reported. Aim: Aim of the study was to evaluate and compare the color and fluoride ion release of conventional and resin-modified GICs in combination with 1.25 and 2.5% chlorhexidine diacetate. Materials and methods: The control groups consisted of conventional GIC and resin-modified GIC. The experimental groups consisted of conventional and resin-modified GIC groups, consisting of 1.25 and 2.5% chlorhexidine. A total of six groups were included with each group being allotted 20 specimens for the evaluation of color stability and 10 specimens each were allotted for the evaluation of fluoride release. Color and fluoride release were recorded using spectrophoto-meter and fluoride selective electrode respectively at 24 hours 7 days and 1 month. Results: Resin-modified GIC groups showed less color stability and better fluoride release at the end of the study compared to conventional GIC groups. Conclusion: There was no significant change in color and fluoride release between 1.25 and 2.5% conventional GIC and also between 1.25 and 2.5% resin-modified GIC combined with chlorhexidine diacetate at the end of the study. Conventional GIC showed better color stability and less fluoride release compared to resin-modified GIC. How to cite this article: Prabhakar AR, Pattanshetti K, Sugandhan S.

IntentSearch: Capturing User Intention for One-Click Internet Image Search

Web-scale image search engines (e.g., Google image search, Bing image search) mostly rely on surrounding text features. It is difficult for them to interpret users' search intention only by query keywords and this leads to ambiguous and noisy search results which are far from satisfactory. It is important to use visual information in order to solve the ambiguity in text-based image retrieval. In this paper, we propose a novel Internet image search approach. It only requires the user to click on one query image with minimum effort and images from a pool retrieved by text-based search are reranked based on both visual and textual content. Our key contribution is to capture the users' search intention from this one-click query image in four steps. 1) The query image is categorized into one of the predefined adaptive weight categories which reflect users' search intention at a coarse level. Inside each category, a specific weight schema is used to combine visual features adaptive to this kind of image to better rerank the text-based search result. 2) Based on the visual content of the query image selected by the user and through image clustering, query keywords are expanded to capture user intention. 3) Expanded keywords are used to enlarge the image pool to contain more relevant images. 4) Expanded keywords are also used to expand the query image to multiple positive visual examples from which new query specific visual and textual similarity metrics are learned to further improve content-based image reranking. All these steps are automatic, without extra effort from the user. This is critically important for any commercial web-based image search engine, where the user interface has to be extremely simple. Besides this key contribution, a set of visual features which are both effective and efficient in Internet image search are designed. Experimental evaluation shows that our approach significantly improves the precision of top-ranked images and also the user experience.
Interleukin-6 via Sputum Induction as Biomarker of Inflammation for Indoor Particulate Matter among Primary School Children in Klang Valley, Malaysia

In the last few years, air within homes have been indicates by various and emerging body as more serious polluted than those outdoor. Prevalence of respiratory inflammation among school children aged 8 and 10 years old attending national primary schools in urban and rural area were conducted in Klang Valley. Two population studies drawn from the questionnaires were used to investigate the association between indoor particulate matter (PM2.5 & PM10) in a home environment and respiratory implication through the understanding of biological responses. Approximately 430 healthy school children of Standard 2 and Standard 5 were selected. Indication of respiratory symptoms using adaptation questionnaire from American Thoracic Society (1978). Sputum sample collection taken for biological analysis. IL-6 then was analyse by using ELISA techniques. Indoor PM2.5 and PM10 were measured using Dust Trak Aerosol Monitor. The mean concentration of PM2.5 (45.38 µg/m3) and PM10 (80.07 µg/m3) in urban home environment is significantly higher compared to those in rural residential area (p=0.001). Similar trend also shows by the prevalence of respiratory symptom. Association were found with PM2.5 and PM10 with the level of IL-6 among school children. A greater exposure to PM2.5 and PM10 are associated with higher expression of IL-6 level suggesting that the concentration of indoor particulate in urban density area significantly influence the health of children.
Limiting Currency Volatility to Stimulate Goods Market Integration: A Price-Based Approach

This paper studies the effect of instrumental and institutional stabilization of exchange rate volatility on the integration of goods markets. Rather than using data on volume of trade, this paper employs a 3-dimensional panel of prices of 95 very disaggregated goods (e.g., light bulbs) in 83 cities around the world during 1990-2000. We find that the impact of an institutional stabilization-currency board or dollarization-promotes market integration far beyond an instrumental stabilization. Among them, long-term currency unions are more effective than more recent currency boards. All have room to improve relative to a U.S. benchmark.
Distinct Value Signals in Anterior and Posterior Ventromedial Prefrontal Cortex

The core feature of an economic exchange is a decision to trade one good for another, based on a comparison of relative value. Economists have long recognized, however, that the value an individual ascribes to a good during decision making (i.e., their relative willingness to trade for that good) does not always map onto the reward they actually experience. Here, we show that experienced value and decision value are represented in distinct regions of ventromedial prefrontal cortex (VMPFC) during the passive consumption of rewards. Participants viewed two categories of rewards—images of faces that varied in their attractiveness and monetary gains and losses—while being scanned using functional magnetic resonance imaging. An independent market task, in which participants exchanged some of the money that they had earned for brief views of attractive faces, determined the relative decision value associated with each category. We found that activation of anterior VMPFC increased with increasing experienced value, but not decision value, for both reward categories. In contrast, activation of posterior VMPFC predicted each individual's relative decision value for face and monetary stimuli. These results indicate not only that experienced value and decision value are represented in distinct regions of VMPFC, but also that decision value signals are evident even in the absence of an overt choice task. We conclude that decisions are made by comparing neural representations of the value of different goods encoded in posterior VMPFC in a common, relative currency.
“I’m Not Mopping the Floors, I’m Putting a Man on the Moon”: How NASA Leaders Enhanced the Meaningfulness of Work by Changing the Meaning of Work

It is assumed that leaders can boost the motivation of employees by communicating the organization’s ultimate aspirations, yet evidence on the effectiveness of this tactic is equivocal. On some occasions, it causes employees to view their work as more meaningful. At other times, it causes them to become dispirited. These inconsistent findings may in part be explained by a paradox: the very features that make ultimate aspirations meaningful—their breadth and timelessness—undermine the ability of employees to see how their daily responsibilities are associated with them. To understand how leaders can help employees resolve this paradox, I analyzed archival evidence to explore the actions of President John F. Kennedy when leading NASA in the 1960s. I found that Kennedy enacted four sensegiving steps, each of which helped employees see a stronger connection between their work and NASA’s ultimate aspirations. When this connection was strongest, employees construed their day-to-day work not as short-term tasks (“I’m building electrical circuits”) but as the pursuit of NASA’s long-term objective (“I’m putting a man on the moon”) and the aspiration this objective symbolized (“I’m advancing science”). My findings redirect research by conceptualizing leaders as architects who motivate employees most effectively when they provide a structural blueprint that maps the connections between employees’ everyday work and the organization’s ultimate aspirations.
Early Host Cell Targets of Yersinia pestis during Primary Pneumonic Plague

Inhalation of Yersinia pestis causes primary pneumonic plague, a highly lethal syndrome with mortality rates approaching 100%. Pneumonic plague progression is biphasic, with an initial pre-inflammatory phase facilitating bacterial growth in the absence of host inflammation, followed by a pro-inflammatory phase marked by extensive neutrophil influx, an inflammatory cytokine storm, and severe tissue destruction. Using a FRET-based probe to quantitate injection of effector proteins by the Y. pestis type III secretion system, we show that these bacteria target alveolar macrophages early during infection of mice, followed by a switch in host cell preference to neutrophils. We also demonstrate that neutrophil influx is unable to limit bacterial growth in the lung and is ultimately responsible for the severe inflammation during the lethal pro-inflammatory phase.
Dilatancy, jamming, and the physics of granulation

Granulation is a process whereby a dense colloidal suspension is converted into pasty granules (surrounded by air) by application of shear. Central to the stability of the granules is the capillary force arising from the interfacial tension between solvent and air. This force appears capable of maintaining a granule in a jammed solid state, under conditions where the same amount of solvent and colloid could also exist as a flowable droplet. We argue that in the early stages of granulation the physics of dilatancy, which requires that a powder expand on shearing, is converted by capillary forces into the physics of arrest. Using a schematic model of colloidal arrest under stress, we speculate upon various jamming and granulation scenarios. Some preliminary experimental results on aspects of granulation in hard-sphere colloidal suspensions are also presented.
Bacteria Metabolically Engineered for Enhanced Phytochelatin Production and Cadmium Accumulation

ABSTRACT Phytochelatins (PCs) with good binding affinities for a wide range of heavy metals were exploited to develop microbial sorbents for cadmium removal. PC synthase from Schizosaccharomyces pombe (SpPCS) was overexpressed in Escherichia coli, resulting in PC synthesis and 7.5-times-higher Cd accumulation. The coexpression of a variant γ-glutamylcysteine synthetase desensitized to feedback inhibition (GshI*) increased the supply of the PC precursor glutathione, resulting in further increases of 10- and 2-fold in PC production and Cd accumulation, respectively. A Cd transporter, MntA, was expressed with SpPCS and GshI* to improve Cd uptake, resulting in a further 1.5-fold increase in Cd accumulation. The level of Cd accumulation in this recombinant E. coli strain (31.6 μmol/g [dry weight] of cells) was more than 25-fold higher than that in the control strain.
Usability evaluation methods: mind the gaps

The strengths and weaknesses of heuristic evaluation have been well researched. Despite known weaknesses, heuristic evaluation is still widely used since formal usability testing (also referred to as empirical user testing) is more costly and time consuming. What has received less attention is the type of information heuristic evaluation conveys in comparison to empirical user testing supported by eye tracking and user observation. If usability methods are combined, it becomes even more important to distinguish the information contribution by each method. This paper investigates the application of two usability evaluation methods, namely heuristic evaluation and empirical user testing supported by eye tracking, to the website of a learning management system with the intent of discovering the difference in the usability information yielded. Heuristic evaluation as an inspection method is accepted to be fundamentally different from empirical user testing. This paper contributes to a deeper understanding of the nature of the differences by identifying the kind of usability problems identified through each method. The findings should be of interest to researchers, designers and usability practitioners involved in website design and evaluation.
NBS/NIST Gas Thermometry From 0 to 660 °C

In the NBS/NIST Gas Thermometry program, constant-volume gas thermometers, a unique mercury manometer, and a highly accurate thermal expansion apparatus have been employed to evaluate temperatures on the Kelvin Thermodynamic Temperature Scale (KTTS) that correspond to particular temperatures on the 1968 International Practical Temperature Scale (IPTS-68). In this paper, we present a summary of the NBS/NIST Gas Thermometry project, which originated with planning activities in the late 1920s and was completed by measurements of the differences t(KTTS)-t(IPTS-68) in the range 0 to 660 °C. Early results of this project were the first to demonstrate the surprisingly large inaccuracy of the IPTS-68 with respect to the KTTS above 0 °C. Advances in several different measurement techniques, development of new, specialized instruments, and two distinct sets of gas thermometry observations have resulted from the project.
