  1. MintHint: Automated Synthesis of Repair Hints

    Kaleeswaran, Shalini; Tulsian, Varun; Kanade, Aditya; Orso, Alessandro

    2013-01-01

    Being able to automatically repair programs is an extremely challenging task. In this paper, we present MintHint, a novel technique for program repair that is a departure from most of today's approaches. Instead of trying to fully automate program repair, which is often an unachievable goal, MintHint performs statistical correlation analysis to identify expressions that are likely to occur in the repaired code and generates, using pattern-matching based synthesis, repair hints from these expr...

  2. A Method for Learning from Hints

    Abu-Mostafa, Yaser S.

    1993-01-01

    We address the problem of learning an unknown function by putting together several pieces of information (hints) that we know about the function. We introduce a method that generalizes learning from examples to learning from hints. A canonical representation of hints is defined and illustrated for new types of hints. All the hints are represented to the learning process by examples, and examples of the function are treated on equal footing with the rest of the hints. During learning, ex...

  5. Complexity hints for economic policy

    Salzano, Massimo

    2007-01-01

    This volume extends the complexity approach to economics. This complexity approach is not a completely new way of doing economics, and that it is a replacement for existing economics, but rather the integration of some new analytic and computational techniques into economists’ bag of tools. It provides some alternative pattern generators, which can supplement existing approaches by providing an alternative way of finding patterns than be obtained by the traditional scientific approach. On this new kind of policy hints can be obtained. The reason why the complexity approach is taking hold now in economics is because the computing technology has advanced. This advance allows consideration of analytical systems that could not previously be considered by economists. Consideration of these systems suggested that the results of the "control-based" models might not extend easily to more complicated systems, and that we now have a method—piggybacking computer assisted analysis onto analytic methods—to start gen...

Gravity dependence on rotation or spin directionis experimentally constrained only at low energies.Here a method based on high energy Compton scattering is developedto measure the gravitational interaction of accelerated charged particles.Within that formalism the Compton spectra measured at HERA rule out the positron's anti-gravity and hint for a gravitati...

  8. Quantum speed problem: Theoretical hints for control

    Lisboa, Alexandre Coutinho; Piqueira, José Roberto Castilho

    2016-06-01

    The transition time between states plays an important role in designing quantum devices as they are very sensitive to environmental influences. Decoherence phenomenon is responsible for possible destructions of the entanglement that is a fundamental requirement to implement quantum information processing systems. If the time between states is minimized, the decoherence effects can be reduced, thus, it is advantageous to the designer to develop expressions for time performance measures. Quantum speed limit (QSL) problem has been studied from the theoretical point of view, providing general results. Considering the implementation of quantum control systems, as the decoherence phenomenon is unavoidable, it is important to apply these general results to particular cases, developing expressions and performance measures, to assist control engineering designers. Here, a minimum time performance measure is defined for quantum control problems, for time-independent or time-dependent Hamiltonians, and applied to some practical examples, providing hints that may be useful for researchers pursuing optimization strategies for quantum control systems.

  10. Structured hints : extracting and abstracting domain expertise.

    Hereld, M.; Stevens, R.; Sterling, T.; Gao, G. R.; Mathematics and Computer Science; California Inst. of Tech.; Louisiana State Univ.; Univ. of Delaware

    2009-03-16

    We propose a new framework for providing information to help optimize domain-specific application codes. Its design addresses problems that derive from the widening gap between the domain problem statement by domain experts and the architectural details of new and future high-end computing systems. The design is particularly well suited to program execution models that incorporate dynamic adaptive methodologies for live tuning of program performance and resource utilization. This new framework, which we call 'structured hints', couples a vocabulary of annotations to a suite of performance metrics. The immediate target is development of a process by which a domain expert describes characteristics of objects and methods in the application code that would not be readily apparent to the compiler; the domain expert provides further information about what quantities might provide the best indications of desirable effect; and the interactive preprocessor identifies potential opportunities for the domain expert to evaluate. Our development of these ideas is progressing in stages from case study, through manual implementation, to automatic or semi-automatic implementation. In this paper we discuss results from our case study, an examination of a large simulation of a neural network modeled after the neocortex.

  14. Hints from Run 1 and prospects from Run 2 at ATLAS

    Bernius, Catrin

    2016-06-01

    The Large Hadron Collider at CERN has allowed the ATLAS experiment to collect a large amount of proton-proton collision data at 7 TeV and 8 TeV centre-of-mass energies throughout Run 1. This dataset was used to discover a Higgs boson with Standard Model-like properties at a mass of about 125 GeV. Furthermore, an impressive number of searches for deviations from the Standard Model expectations have been carried out. To date, no evidence for new physics beyond the SM has been found. However, a few hints in form of 2-3 σ deviations have been observed. After an 18-month shutdown, in which the ATLAS detector has undergone various upgrades, the LHC has again started to deliver collision data at an increased centre-of-mass energy of 13 TeV, providing a much improved sensitivity for various searches, in particular for high mass particles. Some representative hints at the LHC Run 1 are presented, a brief overview of ATLAS upgrades and prospects for SUSY searches with early Run 2 data are given.

  15. Visual-hint Boundary to Segment Algorithm for Image Segmentation

    Su, Yu

    2010-01-01

    Image segmentation has been a very active research topic in image analysis area. Currently, most of the image segmentation algorithms are designed based on the idea that images are partitioned into a set of regions preserving homogeneous intra-regions and inhomogeneous inter-regions. However, human visual intuition does not always follow this pattern. A new image segmentation method named Visual-Hint Boundary to Segment (VHBS) is introduced, which is more consistent with human perceptions. VHBS abides by two visual hint rules based on human perceptions: (i) the global scale boundaries tend to be the real boundaries of the objects; (ii) two adjacent regions with quite different colors or textures tend to result in the real boundaries between them. It has been demonstrated by experiments that, compared with traditional image segmentation method, VHBS has better performance and also preserves higher computational efficiency.

  16. A two-Higgs-doublet model facing experimental hints

    Crivellin Andreas

    2016-01-01

    Full Text Available Physics beyond the Standard Model has so far eluded our experimental probes. Nevertheless, a number of interesting anomalies have accumulated that can be taken as hints towards new physics: BaBar, Belle, and LHCb have found deviations of approximately 3:8σ in B → Dτν and B → D*τν; the anomalous magnetic moment of the muon differs by about 3σ from the theoretic prediction; the branching ratio for τ → μνν is about 2σ above the Standard Model expectation; and CMS and ATLAS found hints for a non-zero decay rate of h → μτ at 2.6σ. Here we consider these processes within a lepton-specific two-Higgs doublet model with additional non-standard Yukawa couplings and show how (and which of these excesses can be accommodated.

  17. Hints of quantum gravity from the horizon fluid

    Cropp, Bethan; Bhattacharya, Swastik; Shankaranarayanan, S.

    2016-01-01

    For many years researchers have tried to glean hints about quantum gravity from black hole thermodynamics. However, black hole thermodynamics suffers from the problem of Universality --- at leading order, several approaches with different microscopic degrees of freedom lead to Bekenstein-Hawking entropy. We attempt to bypass this issue by using a minimal statistical mechanical model for the horizon fluid based on Damour-Navier-Stokes (DNS) equation. For asymptotically flat black hole spacetim...

  18. Summary of hints for new physics from (quark) flavour physics

    Zwicky, Roman(Higgs Centre for Theoretical Physics, School of Physics and Astronomy, University of Edinburgh, Edinburgh EH9 3JZ, Scotland, United Kingdom)

    2008-01-01

    Recently two hints for new physics have emerged: The B_s mixing phase phi_s and the rate of D_s -> (mu,tau) nu exposing a discrepancy of \\sim 3 sigma and 3.8 sigma deviation from the Standard Model respectively. Moreover the difference of the CP asymmetries in B -> K pi between the charged and neutral modes is at the 5.3 sigma level which is somewhat larger than expected. New physics in phi_s or A_CP(B -> K pi) would be in contradiction with the minimal flavour violation hypothesis. ...

  19. HINT-KB: The human interactome knowledge base

    Theofilatos, Konstantinos A.

    2012-01-01

    Proteins and their interactions are considered to play a significant role in many cellular processes. The identification of Protein-Protein interactions (PPIs) in human is an open research area. Many Databases, which contain information about experimentally and computationally detected human PPIs as well as their corresponding annotation data, have been developed. However, these databases contain many false positive interactions, are partial and only a few of them incorporate data from various sources. To overcome these limitations, we have developed HINT-KB (http://150.140.142.24:84/Default.aspx) which is a knowledge base that integrates data from various sources, provides a user-friendly interface for their retrieval, estimates a set of features of interest and computes a confidence score for every candidate protein interaction using a modern computational hybrid methodology. © 2012 IFIP International Federation for Information Processing.

  20. Hints of quantum gravity from the horizon fluid

    Cropp, Bethan; Shankaranarayanan, S

    2016-01-01

    For many years researchers have tried to glean hints about quantum gravity from black hole thermodynamics. However, black hole thermodynamics suffers from the problem of Universality --- at leading order, several approaches with different microscopic degrees of freedom lead to Bekenstein-Hawking entropy. We attempt to bypass this issue by using a minimal statistical mechanical model for the horizon fluid based on Damour-Navier-Stokes (DNS) equation. For asymptotically flat black hole spacetimes in General Relativity, we show explicitly that at equilibrium the entropy of the horizon fluid is the Bekenstein-Hawking entropy. Further we show that, for the bulk viscosity of the fluctuations of the horizon fluid to be identical to Damour, a confinement scale exists for these fluctuations, implying quantization of the horizon area. The implications and possible mechanisms from the fluid point of view are discussed.

  1. Feminizing chicks: a model for avian sex determination based on titration of Hint enzyme activity and the predicted structure of an Asw-Hint heterodimer

    Pace, Helen C.; Brenner, Charles

    2003-01-01

    Background In birds and some lizards, females are heterogametic with a ZW karyotype, while males are ZZ homogametes. The molecular basis for sexual differentiation in birds is unknown: arguments exist for doses of Z masculinizing chicks and for W information feminizing. ASW was identified as a tandemly repeated gene conserved on avian W chromosomes that is expressed in early female development and appears to be an inactive form of avian Z-encoded HINT. Hint is a dimeric enzyme that hydrolyzes...

  4. Hints for Enhanced b -> sg From Charm and Kaon Counting

    Previously, motivation for enhanced b → sg from new flavor physics has centered on discrepancies between theory and experiment. Here two experimental hints are considered: (1) updated measurements of the charm multiplicity and Β((bar B) → Xc|cs) at the Υ(4S) imply Β(B → Xnocharm) ∼ 12.4 ± 5.6%, (2) the (bar B) → K-X and (bar B) → K+/K-X branching fractions are in excess of conventional (bar B) → Xc → KX yields by about 16.9 ± 5.6% and 18 ± 5.3%, respectively. JETSET 7.4 was used to estimate kaon yields from s(bar s) popping in (bar B) → Xc|ud decays. JETSET 7.4 Monte Carlos for Β((bar B) → Xsg) ∼ 15% imply that the additional kaon production would lead to 1σ agreement with observed charged and neutral kaon yields. The Ks momentum spectrum would be consistent with recent CLEO bounds in the end point region. Search strategies for enhanced b → sg are discussed in light of large theoretical uncertainty in the standard model fast kaon background from b → s penguin operators

  5. Acute behavioral effects of nicotine in male and female HINT1 knockout mice.

    Jackson, K J; Wang, J B; Barbier, E; Chen, X; Damaj, M I

    2012-11-01

    Human genetic association and brain expression studies, and mouse behavioral and molecular studies implicate a role for the histidine triad nucleotide-binding protein 1 (HINT1) in schizophrenia, bipolar disorder, depression and anxiety. The high comorbidity between smoking and psychiatric disorders, schizophrenia in particular, is well established. Associations with schizophrenia and HINT1 are also sex specific, with effects more predominant in males; however, it is unknown if sex differences associated with the gene extend to other phenotypes. Thus, in this study, using a battery of behavioral tests, we elucidated the role of HINT1 in acute nicotine-mediated behaviors using male and female HINT1 wild-type (+/+) and knockout (-/-) mice. The results show that male HINT1 -/- mice were less sensitive to acute nicotine-induced antinociception in the tail-flick, but not hot-plate test. At low nicotine doses, male and female HINT1 -/- mice were less sensitive to nicotine-induced hypomotility, although the effect was more pronounced in females. Baseline differences in locomotor activity observed in male HINT1 +/+ and -/- mice were absent in females. Nicotine did not produce an anxiolytic effect in male HINT1 -/- mice, but rather an anxiogenic response. Diazepam also failed to induce an anxiolytic response in these mice, suggesting a general anxiety phenotype not specific to nicotine. Differences in anxiety-like behavior were not observed in female mice. These results further support a role for HINT1 in nicotine-mediated behaviors and suggest that alterations in the gene may have differential effects on phenotype in males and females. PMID:22827509

  8. Hints at diapirism in Arabia Terra craters, Mars

    during bulge sequences deposition. One or - more likely - multiple layers of sulfates below the shallower levels of Arabia Terra surface need, in our opinion, to be hypothesized in order to explain all these contrasting observations. Indeed impact cratering on such an evaporate bearing layered target might have provided the ideal conditions of faulting, interconnectivity of evaporatic beds and lithostatic load release to allow diapirs ascent, In turn diapirism could have been responsible for central bulging as testified by outward dipping strata on stratified bulges, broad un-stratified bulges and folding (see Jackson and Vendeville, 1994 for typical salt tectonics). The depth of the fluid source calculated with a fractal method (Pozzobon et al., 2013) using the position of the small widespread mounds within Firsoff and Crommelin craters can give a hint of the average depth of the evaportic horizons (~4 km). As further developments we plan to test and quantify our model to take into account geological evidences, possible kinematics, rheology and stratigraphic constrains.

  14. A Time Series Analysis of Cancer-Related Information Seeking: Hints From the Health Information National Trends Survey (HINTS) 2003-2014.

    Huerta, Timothy R; Walker, Daniel M; Johnson, Tyler; Ford, Eric W

    2016-09-01

    Recent technological changes, such as the growth of the Internet, have made cancer information widely available. However, it remains unknown whether changes in access have resulted in concomitant changes in information seeking behavior. Previous work explored the cancer information seeking behaviors of the general population using the 2003 Health Information National Trends Survey (HINTS). This article aims to reproduce, replicate, and extend that existing analysis using the original dataset and five additional iterations of HINTS (2007, 2011, 2012, 2013, 2014). This approach builds on the earlier work by quantifying the magnitude of change in information seeking behaviors. Bivariate comparison of the 2003 and 2014 data revealed very similar results; however, the multivariate model including all years of data indicated differences between the original and extended models: individuals age 65 and older were no longer less likely to seek cancer information than the 18-35 reference population, and Hispanics were also no longer less likely to be cancer information seekers. The results of our analysis indicate an overall shift in cancer information seeking behaviors and also illuminate the impact of increased Internet usage over the past decade, suggesting specific demographic groups that may benefit from cancer information seeking encouragement.

  15. Anti-depressant and anxiolytic like behaviors in PKCI/HINT1 knockout mice associated with elevated plasma corticosterone level

    Wang Jia

    2009-11-01

    Full Text Available Abstract Background Protein kinase C interacting protein (PKCI/HINT1 is a small protein belonging to the histidine triad (HIT family proteins. Its brain immunoreactivity is located in neurons and neuronal processes. PKCI/HINT1 gene knockout (KO mice display hyper-locomotion in response to D-amphetamine which is considered a positive symptom of schizophrenia in animal models. Postmortem studies identified PKCI/HINT1 as a candidate molecule for schizophrenia and bipolar disorder. We investigated the hypothesis that the PKCI/HINT1 gene may play an important role in regulating mood function in the CNS. We submitted PKCI/HINT1 KO mice and their wild type (WT littermates to behavioral tests used to study anti-depressant, anxiety like behaviors, and goal-oriented behavior. Additionally, as many mood disorders coincide with modifications of hypothalamic-pituitary-adrenal (HPA axis function, we assessed the HPA activity through measurement of plasma corticosterone levels. Results Compared to the WT controls, KO mice exhibited less immobility in the forced swim (FST and the tail suspension (TST tests. Activity in the TST tended to be attenuated by acute treatment with valproate at 300 mg/kg in KO mice. The PKCI/HINT1 KO mice presented less thigmotaxis in the Morris water maze and spent progressively more time in the lit compartment in the light/dark test. In a place navigation task, KO mice exhibited enhanced acquisition and retention. Furthermore, the afternoon basal plasma corticosterone level in PKCI/HINT1 KO mice was significantly higher than in the WT. Conclusion PKCI/HINT1 KO mice displayed a phenotype of behavioral and endocrine features which indicate changes of mood function, including anxiolytic-like and anti-depressant like behaviors, in conjunction with an elevated corticosterone level in plasma. These results suggest that the PKCI/HINT 1 gene could be important for the mood regulation function in the CNS.

  16. The Diagnostic Accuracy of Truncal Ataxia and HINTS as Cardinal Signs for Acute Vestibular Syndrome

    Carmona, Sergio; Martínez, Carlos; Zalazar, Guillermo; Moro, Marcela; Batuecas-Caletrio, Angel; Luis, Leonel; Gordon, Carlos

    2016-01-01

    The head impulse, nystagmus type, test of skew (HINTS) protocol set a new paradigm to differentiate peripheral vestibular disease from stroke in patients with acute vestibular syndrome (AVS). The relationship between degree of truncal ataxia and stroke has not been systematically studied in patients with AVS. We studied a group of 114 patients who were admitted to a General Hospital due to AVS, 72 of them with vestibular neuritis (based on positive head impulse, abnormal caloric tests, and negative MRI) and the rest with stroke: 32 in the posterior inferior cerebellar artery (PICA) territory (positive HINTS findings, positive MRI) and 10 in the anterior inferior cerebellar artery (AICA) territory (variable findings and grade 3 ataxia, positive MRI). Truncal ataxia was measured by independent observers as grade 1, mild to moderate imbalance with walking independently; grade 2, severe imbalance with standing, but cannot walk without support; and grade 3, falling at upright posture. When we applied the HINTS protocol to our sample, we obtained 100% sensitivity and 94.4% specificity, similar to previously published findings. Only those patients with stroke presented with grade 3 ataxia. Of those with grade 2 ataxia (n = 38), 11 had cerebellar stroke and 28 had vestibular neuritis, not related to the patient’s age. Grade 2–3 ataxia was 92.9% sensitive and 61.1% specific to detect AICA/PICA stroke in patients with AVS, with 100% sensitivity to detect AICA stroke. In turn, two signs (nystagmus of central origin and grade 2–3 Ataxia) had 100% sensitivity and 61.1% specificity. Ataxia is less sensitive than HINTS but much easier to evaluate. PMID:27551274

When we applied the HINTS protocol to our sample, we obtained 100% sensitivity and 94.4% specificity, similar to previously published findings. Only those patients with stroke presented with grade 3 ataxia. Of those with grade 2 ataxia (n = 38), 11 had cerebellar stroke and 28 had vestibular neuritis, not related to the patient's age. Grade 2-3 ataxia was 92.9% sensitive and 61.1% specific to detect AICA/PICA stroke in patients with AVS, with 100% sensitivity to detect AICA stroke. In turn, two signs (nystagmus of central origin and grade 2-3 Ataxia) had 100% sensitivity and 61.1% specificity. Ataxia is less sensitive than HINTS but much easier to evaluate. PMID:27551274

  18. Superfluid density in cuprates: hints on gauge compositeness of the holes

    Marchetti, P A

    2016-01-01

    We show that several features (the three-dimensional XY universality for moderate underdoping, the almost-BCS behaviour for moderate overdoping and the critical exponent) of the superfluid density in hole-doped cuprates hint at a composite structure of the holes. This idea can be implemented in a spin-charge gauge approach to the $t - t' - J$ model and provides indeed good agreement with available experimental data.

    Dolot, Rafał; Kaczmarek, Renata; Sęda, Aleksandra; Krakowiak, Agnieszka; Baraniak, Janina; Nawrot, Barbara

    2016-06-01

    Histidine triad nucleotide-binding protein 1 (HINT1) represents the most ancient and widespread branch in the histidine triad proteins superfamily. HINT1 plays an important role in various biological processes, and it has been found in many species. Here, we report the first structure (at a 2.34Å resolution) of a complex of human HINT1 with a non-hydrolyzable analog of an Ap4A dinucleotide, containing bis-phosphorothioated glycerol mimicking a polyphosphate chain, obtained from a primitive monoclinic space group P21 crystal. In addition, the apo form of hHINT1 at the space group P21 refined to 1.92Å is reported for comparative studies. PMID:26905466

  2. Prescribing Brief Psychotherapy

    Schuyler, Dean

    2000-01-01

    Brief psychotherapy has demonstrated its effectiveness in treating emotional disorders and helping with problems that typically present to primary care physicians. Because practitioners receive little instruction about this treatment option and often have erroneous preconceived ideas about it, psychotherapy remains underprescribed. Effective brief therapy enables the patient to problem-solve, facilitates the relationship with the provider, and ultimately clarifies the patient's situation. Ref...

  3. The boy who would be queen: hints and closets on children's television.

    Dennis, Jeffery P

    2009-01-01

    Although American television programs targeted at children and adolescents posit universal heterosexuality and never openly allude to LGBT persons, a content analysis of 102 episodes of 25 contemporary children's programs revealed many examples of resistance to the heteronormative ideology: intimate same-sex friendships; inclusive statements or stage business; scenes that hint at the existence of same-sex desire; gender-transgressive or otherwise gay-stereotyped characters; and jokes and references that require a knowledge of gay culture. The impact of this resistance on viewers is analyzed through fan fiction and artwork, and potential explanations are examined. PMID:19657933

  6. Technical hints and potential pitfalls in modified radical neck dissection for thyroid cancer

    Lorente, Leyre; Sancho, Juan J.

    2013-01-01

    Modified radical neck dissection (MRND) is often performed in conjunction with total thyroidectomy for the management of thyroid cancer. Prevention of postoperative sequelae after MRND is closely dependent on the avoidance of technical mistakes that may lead to significant complications and long-term morbidity. A thorough technical discussion with emphasis on potential pitfalls is made of the most relevant steps of MRND using the extrafascial approach: fascial dissection, approach to the accessory nerve, posterior limits, upper internal jugular vein (IJV), transverse cervical vessels, thoracic duct and compartment V dissection. Some anatomical hints are emphasized to help the novice surgeon to develop a refined surgical technique, the key to an uneventful postoperative course. PMID:25083480

  7. A megaxion at 750 GeV as a first hint of low scale string theory

    Ibáñez, Luis E.; Martín-Lozano, Víctor

    2016-07-01

    Low scale string models naturally have axion-like pseudoscalars which couple directly to gluons and photons (but not W 's) at tree level. We show how they typically get tree level masses in the presence of closed string fluxes , consistent with the axion discrete gauge symmetry, in a way akin of the axion monodromy of string inflation and relaxion models. We discuss the possibility that the hints for a resonance at 750 GeV recently reported at ATLAS and CMS could correspond to such a heavy axion state ( megaxion). Adjusting the production rate and branching ratios suggest the string scale to be of order M s ≃ 7-104 TeV, depending on the compactification geometry. If this interpretation was correct, one extra Z' gauge boson could be produced before reaching the string threshold at LHC and future colliders.

  8. Hints for clarification of influencing factors in case of occupational liver diseases

    Zober, A.; Raithel, H.; Valentin, H.

    1981-05-01

    Clarification of influencing factors is of great importance in suspected occupational liver diseases. Hints are given on the basis of the author's own experience and after critical evaluation of the relevant literature. Most important are: 1) Establishment of a comprehensive working anamnesis with special regard to specific features of the job, exposure patterns, and all working materials; 2) assessment of the hepatotoxic potential of the suspected working material according to the present state of knowledge in working medicine and toxicology; 3) objectification and quantification of the suspected noxious substances at the place of work by means of air analysis and analysis of the biological matter; 4) differential diagnosis in view of possible competitive influencing factors.

  2. My brief history

    Hawking, Stephen

    2013-01-01

    My Brief History recounts Stephen Hawking’s improbable journey, from his postwar London boyhood to his years of international acclaim and celebrity. Lavishly illustrated with rarely seen photographs, this concise, witty, and candid account introduces readers to a Hawking rarely glimpsed in previous books: the inquisitive schoolboy whose classmates nicknamed him Einstein; the jokester who once placed a bet with a colleague over the existence of a particular black hole; and the young husband and father struggling to gain a foothold in the world of physics and cosmology. Writing with characteristic humility and humor, Hawking opens up about the challenges that confronted him following his diagnosis of ALS at age twenty-one. Tracing his development as a thinker, he explains how the prospect of an early death urged him onward through numerous intellectual breakthroughs, and talks about the genesis of his masterpiece A Brief History of Time—one of the iconic books of the twentieth century.

  3. Strategic forces briefing

    Bing, G.; Chrzanowski, P.; May, M.; Nordyke, M.

    1989-04-06

    The Strategic Forces Briefing'' is our attempt, accomplished over the past several months, to outline and highlight the more significant strategic force issues that must be addressed in the near future. Some issues are recurrent: the need for an effective modernized Triad and a constant concern for force survivability. Some issues derive from arms control: the Strategic Arms Reduction Talks (SALT) are sufficiently advanced to set broad numerical limits on forces, but not so constraining as to preclude choices among weapon systems and deployment modes. Finally, a new administration faced with serious budgetary problems must strive for the most effective strategic forces limited dollars can buy and support. A review of strategic forces logically begins with consideration of the missions the forces are charged with. We begin the briefing with a short review of targeting policy and implementation within the constraints of available unclassified information. We then review each element of the Triad with sections on SLBMs, ICBMs, and Air-Breathing (bomber and cruise missile) systems. A short section at the end deals with the potential impact of strategic defense on offensive force planning. We consider ABM, ASAT, and air defense; but we do not attempt to address the technical issues of strategic defense per se. The final section gives a brief overview of the tritium supply problem. We conclude with a summary of recommendations that emerge from our review. The results of calculation on the effectiveness of various weapon systems as a function of cost that are presented in the briefing are by Paul Chrzanowski.

  6. Hint for normal hierarchy from global analysis of neutrino mass splitting

    Zhang, Yijia

    2013-01-01

    Based on the independent measurements on neutrino mass splitting $|\\Delta m^2_{\\mu\\mu}|$ and $|\\Delta m^2_{21}|$, and the lately released value of $|\\Delta m^2_{ee}|$ by the Daya Bay Collaboration, we carry out a global fit analysis on $\\Delta m^2_{32}$ and $\\Delta m^2_{31}$ in normal hierarchy and inverse hierarchy respectively, suggesting $\\Delta m^2_{32}=(2.42\\pm0.09)\\times10^{-3} \\mbox{eV}^2$ and $\\Delta m^2_{31}=(2.49\\pm0.09)\\times10^{-3} \\mbox{eV}^2$ in normal hierarchy, or $\\Delta m^2_{32}$=$-(2.48\\pm0.09)\\times10^{-3} \\mbox{eV}^2$ and $\\Delta m^2_{31}$=$-(2.40\\pm0.09)\\times10^{-3} \\mbox{eV}^2$ in invert hierarchy. The global analysis reveals a hint for normal hierarchy at a significance of $1\\sigma$, while the confidence level for invert hierarchy is 65%, below the $1\\sigma$ level. It is suggested that further measurements on the effective mass splitting with higher accuracy are necessary to finally determine the neutrino mass hierarchy.

  8. Diagnosing Stroke in Acute Vertigo: The HINTS Family of Eye Movement Tests and the Future of the "Eye ECG".

    Newman-Toker, David E; Curthoys, Ian S; Halmagyi, G Michael

    2015-10-01

    Patients who present to the emergency department with symptoms of acute vertigo or dizziness are frequently misdiagnosed. Missed opportunities to promptly treat dangerous strokes can result in poor clinical outcomes. Inappropriate testing and incorrect treatments for those with benign peripheral vestibular disorders leads to patient harm and unnecessary costs. Over the past decade, novel bedside approaches to diagnose patients with the acute vestibular syndrome have been developed and refined. A battery of three bedside tests of ocular motor physiology known as "HINTS" (head impulse, nystagmus, test of skew) has been shown to identify acute strokes more accurately than even magnetic resonance imaging with diffusion-weighted imaging (MRI-DWI) when applied in the early acute period by eye-movement specialists. Recent advances in lightweight, high-speed video-oculography (VOG) technology have made possible a future in which HINTS might be applied by nonspecialists in frontline care settings using portable VOG. Use of technology to measure eye movements (VOG-HINTS) to diagnose stroke in the acute vestibular syndrome is analogous to the use of electrocardiography (ECG) to diagnose myocardial infarction in acute chest pain. This "eye ECG" approach could transform care for patients with acute vertigo and dizziness around the world. In the United States alone, successful implementation would likely result in improved quality of emergency care for hundreds of thousands of peripheral vestibular patients and tens of thousands of stroke patients, as well as an estimated national health care savings of roughly $1 billion per year. In this article, the authors review the origins of the HINTS approach, empiric evidence and pathophysiologic principles supporting its use, and possible uses for the eye ECG in teleconsultation, teaching, and triage.

    2014-08-10

    HD 100546 is a well-studied Herbig Be star-disk system that likely hosts a close-in companion with compelling observational evidence for an embedded protoplanet at 68 AU. We present Atacama Large Millimeter/Submillimeter Array observations of the HD 100546 disk which resolve the gas and dust structure at (sub)millimeter wavelengths. The CO emission (at 345.795 GHz) originates from an extensive molecular disk (390 ± 20 AU in radius) whereas the continuum emission is more compact (230 ± 20 AU in radius), suggesting radial drift of the millimeter-sized grains. The CO emission is similar in extent to scattered light images indicating well-mixed gas and micrometer-sized grains in the disk atmosphere. Assuming azimuthal symmetry, a single-component power-law model cannot reproduce the continuum visibilities. The visibilities and images are better reproduced by a double-component model: a compact ring with a width of 21 AU centered at 26 AU and an outer ring with a width of 75 ± 3 AU centered at 190 ± 3 AU. The influence of a companion and protoplanet on the dust evolution is investigated. The companion at 10 AU facilitates the accumulation of millimeter-sized grains within a compact ring, ≈20-30 AU, by ≈10 Myr. The injection of a protoplanet at 1 Myr hastens the ring formation (≈1.2 Myr) and also triggers the development of an outer ring (≈100-200 AU). These observations provide additional evidence for the presence of a close-in companion and hint at dynamical clearing by a protoplanet in the outer disk.

  12. Discovery at Young Star Hints Magnetism Common to All Cosmic Jets

    2010-11-01

    Astronomers have found the first evidence of a magnetic field in a jet of material ejected from a young star, a discovery that points toward future breakthroughs in understanding the nature of all types of cosmic jets and of the role of magnetic fields in star formation. Throughout the Universe, jets of subatomic particles are ejected by three phenomena: the supermassive black holes at the cores of galaxies, smaller black holes or neutron stars consuming material from companion stars, and young stars still in the process of gathering mass from their surroundings. Previously, magnetic fields were detected in the jets of the first two, but until now, magnetic fields had not been confirmed in the jets from young stars. "Our discovery gives a strong hint that all three types of jets originate through a common process," said Carlos Carrasco-Gonzalez, of the Astrophysical Institute of Andalucia Spanish National Research Council (IAA-CSIC) and the National Autonomous University of Mexico (UNAM). The astronomers used the National Science Foundation's Very Large Array (VLA) radio telescope to study a young star some 5,500 light-years from Earth, called IRAS 18162-2048. This star, possibly as massive as 10 Suns, is ejecting a jet 17 light-years long. Observing this object for 12 hours with the VLA, the scientists found that radio waves from the jet have a characteristic indicating they arose when fast-moving electrons interacted with magnetic fields. This characteristic, called polarization, gives a preferential alignment to the electric and magnetic fields of the radio waves. "We see for the first time that a jet from a young star shares this common characteristic with the other types of cosmic jets," said Luis Rodriguez, of UNAM. The discovery, the astronomers say, may allow them to gain an improved understanding of the physics of the jets as well as of the role magnetic fields play in forming new stars. The jets from young stars, unlike the other types, emit radiation

  13. Font hinting techniques and the importance of applying these techniques for high-quality display of fonts on the output device screen

    Banjanin Bojan

    2012-06-01

    Full Text Available In the era of contemporary and rapid way of life and with advancing digital technology, the display of electroniccontent on different types of portable devices becomes a part of everyday life. Whether it is on the screen of a TabletPC, mobile phone or e-book reader, the font needs to be designed in such a way that the displayed message isreceived and understood as easy and efficiently as possible.When it comes to digital font, intended for display on screen, it is necessary to take into account the properties ofthe output device and font size to be used. Since the text is intended for display on small screens (especially in caseof portable devices, the used font should be adapted to such conditions, namely, it should be designed so as to bereadable and legible even at small sizes and at different resolutions of the device.The integral part of contemporary outline fonts are additional instructions on how rasterizer is to render letters atlower resolutions and lower font sizes. These instructions are known as hints, or hint mechanisms, and the processof defining these instructions is called hinting.The aim of this paper is to provide a theoretical basis for understanding the issues of the display of small sizes fontson screen. The paper will also elaborate the hinting techniques with emphasis on TrueType hint mechanisms that aremost suitable for high-quality display on the output device screen, as well as some methods of automatic hinting.Theoretical basis introduced here, represent foundation on which further exploration will lay on. It is important forbroadening the knowledge in the field of rasterization and automatic hinting but also for finding new solutions forthe simpler and better hinting.

  14. Brief encounter networks

    Kostakos, Vassilis; Penn, Alan

    2007-01-01

    Many complex human and natural phenomena can usefully be represented as networks describing the relationships between individuals. While these relationships are typically intermittent, previous research has used network representations that aggregate the relationships at discrete intervals. However, such an aggregation discards important temporal information, thus inhibiting our understanding of the networks dynamic behaviour and evolution. We have recorded patterns of human urban encounter using Bluetooth technology thus retaining the temporal properties of this network. Here we show how this temporal information influences the structural properties of the network. We show that the temporal properties of human urban encounter are scale-free, leading to an overwhelming proportion of brief encounters between individuals. While previous research has shown preferential attachment to result in scale-free connectivity in aggregated network data, we found that scale-free connectivity results from the temporal prope...

  15. PsHint1, associated with the G-protein α subunit PsGPA1, is required for the chemotaxis and pathogenicity of Phytophthora sojae.

    Zhang, Xin; Zhai, Chunhua; Hua, Chenlei; Qiu, Min; Hao, Yujuan; Nie, Pingping; Ye, Wenwu; Wang, Yuanchao

    2016-02-01

    Zoospore chemotaxis to soybean isoflavones is essential in the early stages of infection by the oomycete pathogen Phytophthora sojae. Previously, we have identified a G-protein α subunit encoded by PsGPA1 which regulates the chemotaxis and pathogenicity of P. sojae. In the present study, we used affinity purification to identify PsGPA1-interacting proteins, including PsHint1, a histidine triad (HIT) domain-containing protein orthologous to human HIT nucleotide-binding protein 1 (HINT1). PsHint1 interacted with both the guanosine triphosphate (GTP)- and guanosine diphosphate (GDP)-bound forms of PsGPA1. An analysis of the gene-silenced transformants revealed that PsHint1 was involved in the chemotropic response of zoospores to the isoflavone daidzein. During interaction with a susceptible soybean cultivar, PsHint1-silenced transformants displayed significantly reduced infectious hyphal extension and caused a strong cell death in plants. In addition, the transformants displayed defective cyst germination, forming abnormal germ tubes that were highly branched and exhibited apical swelling. These results suggest that PsHint1 not only regulates chemotaxis by interacting with PsGPA1, but also participates in a Gα-independent pathway involved in the pathogenicity of P. sojae.

The DSM-5 defines delirium as a disturbance in attention (reduced ability to direct, focus, sustain, and shift attention and awareness (reduced orientation to the environment. The disturbance develops over a short period of time (usually hours to a few days, represents a change from baseline attention and awareness, and tends to fluctuate in severity ...

  17. Neuroophthalmology A brief Vademecum

    The stunning, intricate interaction between the visual, vestibular and optomotor systems--each a miracle on its own--ensures maintenance of orientation in space as well as visual recognition and target selection despite a host of sensory conflicts and adversary disturbances. Their main goals are to keep a target of interest on the fovea by either maintaining or shifting the direction of gaze in order to produce an accurate internal representation of the visual surroundings, in particular the selected target, and to continuously mirror the spatial relationship between these various visual elements and the self. Not surprising, the implementation of this host of elaborate neural networks encompasses almost every part of the brain, including the brainstem, cerebellum, extrapyramidal system and many areas of the cerebral cortex. Thus far, these systems are among the best investigated in brain research; and enormous knowledge was amassed over the last century employing a variety of techniques, including single cell recordings, eye movement studies, functional imaging and neuropsychological observations. In addition, this prolific line of research has enlightened many fundamental principles of neural and neuronal processing, which have subsequently enriched other fields of brain research as well as computational neuroscience, e.g. the discovery of receptive fields, which have now become a ubiquitous concept in many other areas of neurophysiology. This (improperly) brief, fractional and undoubtedly biased Vademecum is meant to accompany the reader into this marvellous field of neurophysiology and neurology. In particular, it stresses the clinical application of its functional neuroanatomy at the bedside, which, in many respects, is superior to other means of investigating a patient

  2. Electricity Storage. Technology Brief

    Simbolotti, G. [Italian National Agency for New Technologies, Energy and Sustainable Economic Development ENEA, Rome (Italy); Kempener, R. [International Renewable Energy Agency IRENA, Bonn (Germany)

    2012-04-15

    Electricity storage is a key technology for electricity systems with a high share of renewables as it allows electricity to be generated when renewable sources (i.e. wind, sunlight) are available and to be consumed on demand. It is expected that the increasing price of fossil fuels and peak-load electricity and the growing share of renewables will result in electricity storage to grow rapidly and become more cost effective. However, electricity storage is technically challenging because electricity can only be stored after conversion into other forms of energy, and this involves expensive equipment and energy losses. At present, the only commercial storage option is pumped hydro power where surplus electricity (e.g. electricity produced overnight by base-load coal or nuclear power) is used to pump water from a lower to an upper reservoir. The stored energy is then used to produce hydropower during daily high-demand periods. Pumped hydro plants are large-scale storage systems with a typical efficiency between 70% and 80%, which means that a quarter of the energy is lost in the process. Other storage technologies with different characteristics (i.e. storage process and capacity, conversion back to electricity and response to power demand, energy losses and costs) are currently in demonstration or pre-commercial stages and discussed in this brief report: Compressed air energy storage (CAES) systems, Flywheels; Electrical batteries; Supercapacitors; Superconducting magnetic storage; and Thermal energy storage. No single electricity storage technology scores high in all dimensions. The technology of choice often depends on the size of the system, the specific service, the electricity sources and the marginal cost of peak electricity. Pumped hydro currently accounts for 95% of the global storage capacity and still offers a considerable expansion potential but does not suit residential or small-size applications. CAES expansion is limited due to the lack of suitable

  3. Hints for collective effects in identified particle spectra from p-Pb collisions at 5.02 TeV

    First hints for collective dynamics in high-multiplicity p-Pb collisions at LHC were observed in two-particle correlations of unidentified particles. We present results of a systematic fit using a simple blast wave parameterization to identified particle spectra from p-Pb and Pb-Pb collisions as measured by ALICE at LHC. While in Pb-Pb collisions, a large number of particles can be commonly described by a single set of parameters including mass A=2 and A=3 nuclei, also spectra from high-multiplicity p-Pb collisions allow for a description within this rather simple model. Finally, we give predictions for spectra and the nuclear modification factor of mesons carrying a charm or bottom quark.

  5. The intracellular domain of teneurin-1 induces the activity of microphthalmia-associated transcription factor (MITF) by binding to transcriptional repressor HINT1.

    Schöler, Jonas; Ferralli, Jacqueline; Thiry, Stéphane; Chiquet-Ehrismann, Ruth

    2015-03-27

    Teneurins are large type II transmembrane proteins that are necessary for the normal development of the CNS. Although many studies highlight the significance of teneurins, especially during development, there is only limited information known about the molecular mechanisms of function. Previous studies have shown that the N-terminal intracellular domain (ICD) of teneurins can be cleaved at the membrane and subsequently translocates to the nucleus, where it can influence gene transcription. Because teneurin ICDs do not contain any intrinsic DNA binding sequences, interaction partners are required to affect transcription. Here, we identified histidine triad nucleotide binding protein 1 (HINT1) as a human teneurin-1 ICD interaction partner in a yeast two-hybrid screen. This interaction was confirmed in human cells, where HINT1 is known to inhibit the transcription of target genes by directly binding to transcription factors at the promoter. In a whole transcriptome analysis of BS149 glioblastoma cells overexpressing the teneurin-1 ICD, several microphthalmia-associated transcription factor (MITF) target genes were found to be up-regulated. Directly comparing the transcriptomes of MITF versus TEN1-ICD-overexpressing BS149 cells revealed 42 co-regulated genes, including glycoprotein non-metastatic b (GPNMB). Using real-time quantitative PCR to detect endogenous GPNMB expression upon overexpression of MITF and HINT1 as well as promoter reporter assays using GPNMB promoter constructs, we could demonstrate that the teneurin-1 ICD binds HINT1, thus switching on MITF-dependent transcription of GPNMB.

  12. A Brief History of Context

    Wan, Kaiyu

    2009-01-01

    Context is a rich concept and is an elusive concept to define. The concept of context has been studied by philosophers, linguists, psychologists, and recently by computer scientists. Within each research community the term context was interpreted in a certain way that is well-suited for their goals, however no attempt was made to define context. In many areas of research in computer science, notably on web-based services, human-computer interaction (HCI), ubiquitous computing applications, and context-aware systems there is a need to provide a formal operational definition of context. In this brief survey an account of the early work on context, as well as the recent work on many working definitions of context, context modeling, and a formalization of context are given. An attempt is made to unify the different context models within the formalization. A brief commentary on the usefulness of the formalization in the development of context-aware and dependable systems is included.

  13. Earnings in e-learning: knowledge, CME credits or both? Hints from analysis of attendance dynamics and users' behaviour.

    Mazzoleni, M Cristina; Rognoni, Carla; Finozzi, Enrico; Landro, Mauro; Capodaglio, Edda; Imbriani, Marcello; Giorgi, Ines

    2010-01-01

    Many papers report and convey positive opinion about the use of e-learning in the healthcare sector. The issue is how to exploit at best such a powerful instrument. Starting from data regarding the usage of a CME e-learning course, attendance dynamics and users' behaviour have been inspected with the aim of getting some hints about how to improve the development and the delivery of e-learning courses for CME, and to promote knowledge acquisition at best. The different paths followed by 7811 users have been modeled, from enrolment to conclusion/drop-out, then the behaviour in terms of effort, elapsed time, achieved result have been analyzed. The obtained results point out: good acceptance (retention rate 83%) of a not basic educational model and effectiveness (success rate 79%). At the same time the inspection of behaviour has shown that there is a good margin of possible improvement in terms of knowledge acquisition. Conclusions provide a list of issues to keep in mind during system development, in order to provide CME e-learning meeting both credit and knowledge acquisition goals. PMID:20841752

  17. Evolution of hedgehog and hedgehog-related genes, their origin from Hog proteins in ancestral eukaryotes and discovery of a novel Hint motif

    Bürglin Thomas R

    2008-03-01

    Full Text Available Abstract Background The Hedgehog (Hh signaling pathway plays important roles in human and animal development as well as in carcinogenesis. Hh molecules have been found in both protostomes and deuterostomes, but curiously the nematode Caenorhabditis elegans lacks a bona-fide Hh. Instead a series of Hh-related proteins are found, which share the Hint/Hog domain with Hh, but have distinct N-termini. Results We performed extensive genome searches of the cnidarian Nematostella vectensis and several nematodes to gain further insights into Hh evolution. We found six genes in N. vectensis with a relationship to Hh: two Hh genes, one gene with a Hh N-terminal domain fused to a Willebrand factor type A domain (VWA, and three genes containing Hint/Hog domains with distinct novel N-termini. In the nematode Brugia malayi we find the same types of hh-related genes as in C. elegans. In the more distantly related Enoplea nematodes Xiphinema and Trichinella spiralis we find a bona-fide Hh. In addition, T. spiralis also has a quahog gene like C. elegans, and there are several additional hh-related genes, some of which have secreted N-terminal domains of only 15 to 25 residues. Examination of other Hh pathway components revealed that T. spiralis - like C. elegans - lacks some of these components. Extending our search to all eukaryotes, we recovered genes containing a Hog domain similar to Hh from many different groups of protists. In addition, we identified a novel Hint gene family present in many eukaryote groups that encodes a VWA domain fused to a distinct Hint domain we call Vint. Further members of a poorly characterized Hint family were also retrieved from bacteria. Conclusion In Cnidaria and nematodes the evolution of hh genes occurred in parallel to the evolution of other genes that contain a Hog domain but have different N-termini. The fact that Hog genes comprising a secreted N-terminus and a Hog domain are also found in many protists suggests that this

  4. Enhanced models for stellar Doppler noise reveal hints of a 13-year activity cycle of 55 Cancri

    Baluev, Roman V.

    2015-01-01

    We consider the impact of Doppler noise models on the statistical robustness of the exoplanetary radial velocity fits. We show that the traditional model of the Doppler noise with an additive jitter can generate large non-linearity effects, decreasing the reliability of the fit, especially in the cases when a correlated Doppler noise is involved. We introduce a regularization of the additive noise model that can gracefully eliminate its singularities together with the associated non-linearity effects. We apply this approach to Doppler time series data of several exoplanetary systems. It demonstrates that our new regularized noise model yields orbital fits that have either increased or at least the same statistical robustness, in comparison with the simple additive jitter. Various statistical uncertainties in the parametric estimations are often reduced, while planet detection significance is often increased. Concerning the 55 Cnc five-planet system, we show that its Doppler data contain significant correlated (`red') noise. Its correlation time-scale is in the range from days to months, and its magnitude is much larger than the effect of the planetary N-body perturbations in the radial velocity (these perturbations thus appear undetectable). Characteristics of the red noise depend on the spectrograph/observatory, and also show a cyclic time variation in phase with the public Ca II H&K and photometry measurements. We interpret this modulation as a hint of the long-term activity cycle of 55 Cnc, similar to the solar 11-yr cycle. We estimate the 55 Cnc activity period by 12.6± ^{2.5}_{1.0} yr, with the nearest minimum presumably expected in 2014 or 2015.

  11. A new crystal form of human histidine triad nucleotide-binding protein 1 (hHINT1) in complex with adenosine 5′-monophosphate at 1.38 Å resolution

    The atomic structure of a new crystal form of the human histidine triad nucleotide-binding protein 1 (hHINT1)–AMP complex is reported at 1.38 Å resolution. Histidine triad nucleotide-binding protein 1 (HINT1) represents the most ancient and widespread branch of the histidine triad protein superfamily. HINT1 plays an important role in various biological processes and has been found in many species. Here, the structure of the human HINT1–adenosine 5′-monophosphate (AMP) complex at 1.38 Å resolution obtained from a new monoclinic crystal form is reported. The final structure has Rcryst = 0.1207 (Rfree = 0.1615) and the model exhibits good stereochemical quality. Detailed analysis of the high-resolution data allowed the details of the protein structure to be updated in comparison to the previously published data

  12. Using the Internet to Help With Diet, Weight, and Physical Activity: Results From the Health Information National Trends Survey (HINTS)

    McCully, Scout N; Don, Brian P

    2013-01-01

    Background The Internet offers a viable platform for cost-effective and wide-reaching health interventions. However, little is known about use of the Internet to help with diet, weight, and physical activity (DWPA) using a nationally representative sample from the United States. Objective To (1) assess the demographic characteristics of people who use the Internet to help with DWPA, (2) assess whether usage trends changed over time, and (3) investigate the associations between using the Internet for DWPA and health behaviors. Methods Data on Internet users from the 2007 and 2011 iterations of the Health Information National Trends Survey (HINTS), N=4827 were analyzed using multiple logistic regression to determine the demographic correlates of using the Internet for help with DWPA. Multiple linear regression was used to test the associations between Internet use for DWPA and three health behaviors: fruit intake, vegetable intake, and physical activity. Results A larger percentage of Internet users used the Internet for DWPA in 2011 (42.83%) than in 2007 (40.43%). In general, Internet users who were younger (OR 0.98, P<.001), more educated (OR 1.40, P<.001), married (OR 1.06, P=.03), of a minority race (non-Hispanic blacks: OR 1.14, P=.02; Hispanics: OR 1.42, P=.01), and who had a higher Body Mass Index (BMI) (OR 1.04, P<.001) were more likely to use the Internet for DWPA. Across survey years, gender was not associated with using the Internet for DWPA (OR 1.03, P=.12), but there was a significant interaction between survey year and gender (OR 1.95, P=.002); in 2007, men were more likely to use the Internet for DWPA, but women were more likely to do so in 2011. Using the Internet for DWPA was associated with more vegetable intake (B=.22, P=.002), more fruit intake (B=.19, P=.001), and more moderate exercise (B=.25, P=.001), although the strength of the associations between using the Internet for DWPA and fruit intake and exercise was weaker in 2011 than in 2007

Since its beginnings in the 1950's decade to the present time, videogames have progressively changed from a hobby for ingeneering studens to the most powerfull leisure industry. In order to gain a better understanding of this phenomenon it is necessary to look over the path of its transformation from a retrospecive point of view. Such a look has necessarily to focus on those devices and games that had made a landmark in the history of videogames, taking them to their current position. Besides, it is crucial to address their implications in contemporary visual culture, along with current prejudices against them. This is a short account about a great history.

  1. Elliptic flow: a brief review

    Snellings, Raimond

    2011-05-01

    One of the fundamental questions in the field of subatomic physics is the question of what happens to matter at extreme densities and temperatures as may have existed in the first microseconds after the Big Bang and exists, perhaps, in the core of dense neutron stars. The aim of heavy-ion physics is to collide nuclei at very high energies and thereby create such a state of matter in the laboratory. The experimental program began in the 1990s with collisions made available at the Brookhaven Alternating Gradient Synchrotron (AGS) and the CERN Super Proton Synchrotron (SPS), and continued at the Brookhaven Relativistic Heavy-Ion Collider (RHIC) with the maximum center-of-mass energies of \\sqrt{s_{NN}} = 4.75 , 17.2 and 200 GeV, respectively. Collisions of heavy ions at the unprecedented energy of 2.76 TeV recently became available at the LHC collider at CERN. In this review, I give a brief introduction to the physics of ultrarelativistic heavy-ion collisions and discuss the current status of elliptic flow measurements.

  4. The human interactome knowledge base (hint-kb): An integrative human protein interaction database enriched with predicted protein–protein interaction scores using a novel hybrid technique

    Theofilatos, Konstantinos A.

    2013-07-12

    Proteins are the functional components of many cellular processes and the identification of their physical protein–protein interactions (PPIs) is an area of mature academic research. Various databases have been developed containing information about experimentally and computationally detected human PPIs as well as their corresponding annotation data. However, these databases contain many false positive interactions, are partial and only a few of them incorporate data from various sources. To overcome these limitations, we have developed HINT-KB (http://biotools.ceid.upatras.gr/hint-kb/), a knowledge base that integrates data from various sources, provides a user-friendly interface for their retrieval, cal-culatesasetoffeaturesofinterest and computesaconfidence score for every candidate protein interaction. This confidence score is essential for filtering the false positive interactions which are present in existing databases, predicting new protein interactions and measuring the frequency of each true protein interaction. For this reason, a novel machine learning hybrid methodology, called (Evolutionary Kalman Mathematical Modelling—EvoKalMaModel), was used to achieve an accurate and interpretable scoring methodology. The experimental results indicated that the proposed scoring scheme outperforms existing computational methods for the prediction of PPIs.

  14. OBSERVATIONS OF INFALLING AND ROTATIONAL MOTIONS ON A 1000 AU SCALE AROUND 17 CLASS 0 AND 0/I PROTOSTARS: HINTS OF DISK GROWTH AND MAGNETIC BRAKING?

    We perform imaging and analyses of SMA 1.3 mm continuum, C18O (2-1) and 12CO (2-1) line data of 17 Class 0 and 0/I protostars to study their gas kinematics on a 1000 AU scale. Continuum and C18O (2-1) emission are detected toward all the sample sources and show central primary components with sizes of ∼600-1500 AU associated with protostars. The velocity gradients in C18O (2-1) have wide ranges of orientations from parallel to perpendicular to the outflows, with magnitudes from ∼1 to ∼530 km s–1 pc–1. We construct a simple kinematic model to reproduce the observed velocity gradients, estimate the infalling and rotational velocities, and infer the disk radii and the protostellar masses. The inferred disk radii range from <5 AU to >500 AU with estimated protostellar masses from <0.1 M ☉ to >1 M ☉. Our results hint that both large and small disks are possibly present around Class 0 protostars, which could be a sign of disk growth at the Class 0 stage. In addition, the directions of the overall velocity gradients in 7 out of the 17 sources are close to perpendicular to their outflow axes (Δθ > 65°), which is a signature of significant rotational motions. From our model fitting, the specific angular momenta in these sources are estimated to be >2 × 10–4 km s–1 pc, suggesting that magnetic braking is unlikely efficient on a 1000 AU scale in these Class 0 and 0/I sources. In a sub-sample with observed magnetic field orientations, we find no source with large specific angular momenta together with closely aligned magnetic field and outflow axes. This possibly hints that the magnetic field, if originally aligned with the rotational axis, can play a role in removing angular momentum from infalling material at the Class 0 stage. We discuss our results in comparison with theoretical models of collapsing dense cores with and without magnetic fields in the context of disk formation

  1. Similarity of structuring in the range 10^{-5} cm to 10^23 cm hints at a baryonic cold dark skeleton of the Universe

    Kukushkin, A B

    2002-01-01

    The presence of skeletal structures of the same distinctive topology (cartwheels, tubules, etc.), in the range 10^{-5} - 10^23 cm, and a trend toward self-similarity of these structures are found. These evidences come from the electron micrography of dust deposits in tokamak (10^{-6} - 10^{-3}cm), the images of plasma taken in laboratory electric discharges -- tokamaks, Z-pinches, plasma focus and vacuum spark (10^{-2} - 10 cm), hail particles (1-10 cm), the images of tornado (10^3 - 10^5 cm), the Hubble Space Telescope and Chandra X-Ray Observatory public archives' images (up to 10^23 cm). The redshift surveys of galaxies and quasars suggests the possibility to draw the above similarity farther, up to 10^26 cm. The above similarity hints at the presence of a baryonic cold dark skeleton (BCDS) of the Universe, which -- in the entire range 10^{-5} - 10^26 cm -- may contain ordinary matter in a fractal condensed form like that in the above-mentioned dust skeletons and hail particles. The probable compatibility ...

Continuum and C18O (2-1) emission are detected toward all the sample sources and show central primary components with sizes of ~600-1,500 AU associated with protostars. The velocity gradients in C18O (2-1) have wide ranges of orientations from parallel to perpendicular to the outflows, with magnitudes from ~1 to ~530 km/s/pc. We construct a simple kinematic model to reproduce the observed velocity gradients, estimate the infalling and rotational velocities, and infer the disk radii and the protostellar masses. The inferred disk radii range from 500 AU with estimated protostellar masses from 1 Msun. Our results hint that both large and small disks are possibly present around Class 0 protostars, which could be a sign of disk growth at the Class 0 stage. In addition, the directions of the overall velocity gradients in 7 out of the 17 sour...

We first introduce the FRW models and their flat solutions for energy fluids playing an important role in the dynamics at different epochs. We then introduce different cosmological lengths and some of their applications. The later part is dedicated to the physical processes and concepts necessary to understand the early and very early Universe and observations of it.

  6. Dual activity of certain HIT-proteins: A. thaliana Hint4 and C. elegans DcpS act on adenosine 5'-phosphosulfate as hydrolases (forming AMP) and as phosphorylases (forming ADP).

    Guranowski, Andrzej; Wojdyła, Anna Maria; Zimny, Jarosław; Wypijewska, Anna; Kowalska, Joanna; Jemielity, Jacek; Davis, Richard E; Bieganowski, Paweł

    2010-01-01

    Histidine triad (HIT)-family proteins interact with different mono- and dinucleotides and catalyze their hydrolysis. During a study of the substrate specificity of seven HIT-family proteins, we have shown that each can act as a sulfohydrolase, catalyzing the liberation of AMP from adenosine 5'-phosphosulfate (APS or SO(4)-pA). However, in the presence of orthophosphate, Arabidopsis thaliana Hint4 and Caenorhabditis elegans DcpS also behaved as APS phosphorylases, forming ADP. Low pH promoted the phosphorolytic and high pH the hydrolytic activities. These proteins, and in particular Hint4, also catalyzed hydrolysis or phosphorolysis of some other adenylyl-derivatives but at lower rates than those for APS cleavage. A mechanism for these activities is proposed and the possible role of some HIT-proteins in APS metabolism is discussed. PMID:19896942

    Although ITSs are supposed to adapt to differences among learners, so far, little attention has been paid to how they might adapt to differences in how students learn from help. When students study with an Intelligent Tutoring System, they may receive multiple types of help, but may not comprehend and make use of this help in the same way. To…

  8. The Raychaudhuri equations: A brief review

    Sayan Kar; Soumitra Sengupta

    2007-07-01

    We present a brief review on the Raychaudhuri equations. Beginning with a summary of the essential features of the original article by Raychaudhuri and subsequent work of numerous authors, we move on to a discussion of the equations in the context of alternate non-Riemannian spacetimes as well as other theories of gravity, with a special mention on the equations in spacetimes with torsion (Einstein–Cartan–Sciama–Kibble theory). Finally, we give an overview of some recent applications of these equations in general relativity, quantum field theory, string theory and the theory of relativisitic membranes. We conclude with a summary and provide our own perspectives on directions of future research.

    张莉; 尚彦飞

    2014-01-01

    William Blake (1757-1827) is a renowned British poet in the 18th century. His lyric poems display the characteristics of romantic spirit, and he is regarded as the forefather of the British Romanticism. His London is a well-known lyric poetry, which is thought to be the best vesicle in the West. This paper will analyse this poem in terms of its form, theme, and im-age and then draw a brief conclusion for the characteristics of William Blake's poem.

  10. Brief history of electronic stereoscopic displays

    Lipton, Lenny

    2012-02-01

    A brief history of recent developments in electronic stereoscopic displays is given concentrating on products that have succeeded in the market place and hence have had a significant influence on future implementations. The concentration is on plano-stereoscopic (two-view) technology because it is now the dominant display modality in the marketplace. Stereoscopic displays were created for the motion picture industry a century ago, and this technology influenced the development of products for science and industry, which in turn influenced product development for entertainment.

  11. A brief history of topographical anatomy.

    Standring, Susan

    2016-07-01

    This brief history of topographical anatomy begins with Egyptian medical papyri and the works known collectively as the Greco-Arabian canon, the time line then moves on to the excitement of discovery that characterised the Renaissance, the increasing regulatory and legislative frameworks introduced in the 18th and 19th centuries, and ends with a consideration of the impact of technology that epitomises the period from the late 19th century to the present day. This paper is based on a lecture I gave at the Winter Meeting of the Anatomical Society in Cambridge in December 2015, when I was awarded the Anatomical Society Medal. PMID:27278889

  14. Brief historical background of Miamisburg Indian Mound

    Russell, Lorraine M. [comp.

    1960-01-01

    The construction of Mound Laboratory was completed in 1948. The name Mound Laboratory was chosen for this installation because of the major Indian Mound which is immediately adjacent to the Plant site. Frequent inquiries of visitors to Mound Lab concerning the Indian Mounds in general and specifically Miamisburg's Indian Mound has indicated an area of "outside interest". We, therefore, thought it would be appropriate to furnish this brief historical background to all of the attendees at the Twentieth Meeting of the Mechanical Equipment Management Subgroup.

  16. Fast healthcare: brief communication, traps and opportunities.

    Crawford, Paul; Brown, Brian

    2011-01-01

    Resource considerations have meant that brevity in health care interventions is a high priority, and have led to a constant striving after ever more impressive time efficiency. The UK's National Health Service may be described as a kind of 'fast healthcare', where everyone is task busy, time is money, bed spaces are frenetically shuffled so as to accommodate the most needy and there appears to be 'no time to talk'. Indeed, a great many health care encounters are taking place in short 'blips' often of 5min or less across a range of sites and involving a vast number of practitioners. In this paper we explore how brief communication can both alienate and be therapeutic for patients. We theorise brief interactions by considering a number of traditions of work in anthropology, linguistics and sociology and conclude that health care providers need to invest much more in the skills and strategies for how best to communicate briefly if it to retain its core tradition of caring for others.

  19. Bats and Viruses: a Brief Review

    Lin-Fa Wang

    2009-01-01

    Bats, probably the most abundant, diverse and geographically dispersed vertebrates on earth, have recently been shown to be the reservoir hosts of a number of emerging viruses responsible for severe human and livestock disease outbreaks. Flying foxes have been demonstrated to be the natural reservoir for Hendra and Nipah viruses. Evidence supporting the possibility of bats as potential reservoirs for SARS coronavirus (SARS-CoV) and Ebola virus has also been reported. The recent discovery of these viruses and other viruses occurring naturally in the bat population provides a unique insight into a diverse pool of potentially emergent and pathogenic viruses. The factors which influence the ability of zoonotic viruses to effectively cross the species barrier from bats to other animal populations are poorly understood. A brief review is provided here on the recently emerged bat viruses and on current and future strategies for research in this area.

  20. Delusional disorders in dermatology: a brief review.

    Robles, David T; Romm, Sharon; Combs, Heidi; Olson, Jonathan; Kirby, Phil

    2008-01-01

    There are several unique psychiatric disorders that are likely to present to a dermatologist because of their accompanying skin complaints. Delusions of parasitosis (DP) is a fixed, false belief of parasitic infestation that may lead patients to compulsively self-mutilate while attempting to remove the non-existent parasites. Morgellons disease is a controversial condition characterized by a fixed belief that fibers that are imbedded or extruding from the skin; this condition is likely in the spectrum of DP. Body dysmorphic disorder (BDD) is a preoccupation with an imagined defect in appearance that causes significant distress and is associated with time consuming rituals, isolation, depression, and increased risk of suicide. Olfactory reference syndrome (ORS) is a preoccupation with body odor leading to the stigmata of shame, embarrassment, and social isolation. This brief review examines each of these conditions and their management because any one of them may present to a dermatologist. PMID:18713583

  1. Affordances for robots: a brief survey

    Thomas E. Horton

    2012-12-01

    Full Text Available In this paper, we consider the influence of Gibson's affordance theory on the design of robotic agents. Affordance theory (and the ecological approach to agent design in general has in many cases contributed to the development of successful robotic systems; we provide a brief survey of AI research in this area. However, there remain significant issues that complicate discussions on this topic, particularly in the exchange of ideas between researchers in artificial intelligence and ecological psychology. We identify some of these issues, specifically the lack of a generally accepted definition of "affordance" and fundamental differences in the current approaches taken in AI and ecological psychology. While we consider reconciliation between these fields to be possible and mutually beneficial, it will require some flexibility on the issue of direct perception.

  6. The nuclear materials control technology briefing book

    Hartwell, J.K.; Fernandez, S.J.

    1992-03-01

    As national and international interests in nuclear arms control and non-proliferation of nuclear weapons, intensify, it becomes ever more important that contributors be aware of the technologies available for the measurement and control of the nuclear materials important to nuclear weapons development. This briefing book presents concise, nontechnical summaries of various special nuclear material (SNM) and tritium production monitoring technologies applicable to the control of nuclear materials and their production. Since the International Atomic Energy Agency (IAEA) operates a multinational, on-site-inspector-based safeguards program in support of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), many (but not all) of the technologies reported in this document are in routine use or under development for IAEA safeguards.

  7. History of Hanford Site Defense Production (Brief)

    This paper acquaints the audience with the history of the Hanford Site, America's first full-scale defense plutonium production site. The paper includes the founding and basic operating history of the Hanford Site, including World War II construction and operations, three major postwar expansions (1947-55), the peak years of production (1956-63), production phase downs (1964-the present), a brief production spurt from 1984-86, the end of the Cold War, and the beginning of the waste cleanup mission. The paper also delineates historical waste practices and policies as they changed over the years at the Hanford Site, past efforts to chemically treat, ''fractionate,'' and/or immobilize Hanford's wastes, and resulting major waste legacies that remain today. This paper presents original, primary-source research into the waste history of the Hanford Site. Finally, the paper places the current Hanford Site waste remediation endeavors in the broad context of American and world history

  8. Brief fasting, stress, and cognition in children.

    Pollitt, E; Leibel, R L; Greenfield, D

    1981-08-01

    Effects of skipping breakfast on speed and accuracy of response in a number of problem solving tasks were assessed in 9- to 11-yr-old, well-nourished children. The conceptual framework for this study was derived from an experimental model of the effects of mild environmental stress, e.g., noise, on human performance. Plasma glucose, beta-hydroxybutyrate, lactate, and free fatty acids were used as indicators of the induced metabolic stress, and the extent of their association with the behavioral measures was determined. Fasting had an adverse effect on the accuracy of responses in problem solving, but it had a beneficial effect on immediate recall in short-term memory. Both effects are explained by a heightened arousal level associated with the brief experimental fast. PMID:7270476

  9. Brief overview of geophysical probing technology

    An evaluation of high-resolution geophysical techniques which can be used to characterize a nulcear waste disposal site is being conducted by the Lawrence Livermore National Laboratory (LLNL) at the request of the US Nuclear Regulatory Commisson (NRC). LLNL is involved in research work aimed at evaluating the current capabilities and limitations of geophysical methods used for site selection. This report provides a brief overview of the capabilities and limitations associated with this technology and explains how our work addresses some of the present limitations. We are examining both seismic and electromagnetic techniques to obtain high-resolution information. We are also assessing the usefulness of geotomography in mapping fracture zones remotely. Finally, we are collecting core samples from a site in an effort to assess the capability of correlating such geophysical data with parameters of interest such as fracture continuity, orientation, and fracture density

  10. Brief description of the Wackersdorf Reprocessing Facility

    The DWK is now planning the construction and operation of a facility for the reprocessing of spent fuel elements and the fabrication of mixed-oxide fuel elements which will initially have an average daily throughput of 2 tons (t) of nuclear fuel. The application required by the Atomic Law was submitted to the Bavarian State Ministry for State Development and Environmental Matters on October 28, 1982. According to Par. 3, Section 1, No. 1 of the Atomic Law Procedural Ordinance such an application for permission in accordance with par. 7 AtL must explicitly be accompanied by a safety report which shall make it possible for third parties to make a judgment whether the impacts associated with the facility and its operation could damage their rights. The safety report is intended to present and explain the concept of the facility, the safety-technological design bases, and the operation of the plant, including its operation and safety systems and the impacts and proposed preventive measures. In addition to the detailed presentations in the safety report, Par. 3 of the Atomic Law Procedural Ordinance also requires a brief description of the plant designed for general public understanding, suitable for the design, which will also explain the expected impacts on the general environment and the surrounding area. Hence the brief description presents and explains the following matters: the site; the technology and state of the art for reprocessing of spent nuclear fuel; the structure and function of the proposed facility; safety provisions of the proposed facility and the management of perturbations in operation; the impacts of the facility and its operation on the environment; measures to be taken for dealing with the radioactive wastes; and provisions for ultimate shut-down of the facility

  9. A Brief History of Black Holes

    Crothers S. J.

    2006-04-01

    Full Text Available Neither the layman nor the specialist, in general, have any knowledge of the historical circumstances underlying the genesis of the idea of the Black Hole. Essentially, almost all and sundry simply take for granted the unsubstantiated allegations of some ostentatious minority of the relativists. Unfortunately, that minority has been rather careless with the truth and is quite averse to having its claims corrected, notwithstanding the documentary evidence on the historical record. Furthermore, not a few of that vainglorious and disingenuous coterie, particularly amongst those of some notoriety, attempt to dismiss the testimony of the literature with contempt, and even deliberate falsehoods, claiming that history is of no importance. The historical record clearly demonstrates that the Black Hole has been conjured up by combination of confusion, superstition and ineptitude, and is sustained by widespread suppression of facts, both physical and theoretical. The following essay provides a brief but accurate account of events, verifiable by reference to the original papers, by which the scandalous manipulation of both scientific and public opinion is revealed

  10. Market brief : natural gas in Turkey

    Turkey may soon become an important transit route to Europe for natural gas imported from the Caucasus, Iran, and other Middle Eastern countries. This market brief provided an overview of Turkey's natural gas market and industry, and examined investment and business opportunities for Canadian businesses. Consumption of natural gas in Turkey has grown by 14.8 per cent annually in the last decade. Transmission equipment expenditures total approximately $400 million annually. It is expected that the demand for environmental and engineering services for natural gas-related industries will grow by 15 per cent annually over the next decade. There are currently several opportunities for Canadian suppliers of equipment, engineering, and construction services. Turkey's expected full European Union (EU) membership will require Turkey to adopt EU environmental and emissions standards. Potential investors in Turkey require operating licences from Turkey's Energy Market Regulatory Authority (EMRA). All state procurement is by tender, while BOTAS, the state-owned gas company dominates both imports and the transmission of gas. Market entry considerations were also presented. 7 refs., 4 tabs., 2 figs

Dr. Ed Weiler (HST Program Scientist, NASA Headquarters), Dr. Dave Leckrone (HST, Senior Project Scientist, Goddard Space Flight Center (GSFC)), Dr. John Trauger (Wide Field Planetary Camera 2 (WFPC2) Principal Investigator, Jet Propulsion Lab. (JPL)), Dr. Chris Burrows (WFPC2 Co-Investigator, Space Telescope Science Inst.(STSci)-European Space Agency (ESA), Jim Crocker ((Corrective Optics Space Telescope Axial Replacement) COSTAR Team Leader, STSci), Dr. Holland Ford (COSTAR Project Scientist, Johns Hopkins Univ., STSci), and Dr. Duccio Machetto (European Space Agency (ESA)) give brief presentations, which feature images of stars and galaxies taken from the ground, from WFPC1 (prior to the servicing mission), and from WFPC2 (after the servicing mission). The main theme of the discussions center around the spherical aberration that was found in the images prior to servicing and the corrected images seen without the aberration following servicing. A question and answer period rounds out the press conference, with questions posed from scientific journalists at GSFC and other NASA centers.

  12. Briefing highlights space weather risks to GPS

    Tretkoff, Ernie

    2011-07-01

    Solar storms, which are expected to increase as the Sun nears the most active phase of the solar cycle, can disrupt a variety of technologies on which society relies. Speakers at a 22 June briefing on Capitol Hill in Washington, D. C., focused on how space weather can affect the Global Positioning System (GPS), which is used in a wide range of industries, including commercial air travel, agriculture, national security, and emergency response. Rocky Stone, chief technical pilot for United Airlines, noted that GPS allows more aircraft to be in airspace, saves fuel, and helps aircraft move safely on runways. “Improvements in space weather forecasting need to be pursued,” he said. Precision GPS has also “changed the whole nature of farming,” said Ron Hatch, Director of Navigation Systems, NavCom Technology/John Deere. GPS makes it possible for tractors to be driven in the most efficient paths and for fertilizer and water to be applied precisely to the areas that most need them. Space weather-induced degradation of GPS signals can cause significant loss to farms that rely on GPS. Elizabeth Zimmerman, Deputy Associate Administrator for the Office of Response and Recovery at the Federal Emergency Management Agency (FEMA), described how FEMA relies on GPS for disaster recovery. The agency is developing an operations plan for dealing with space weather, she said.

  13. Market Brief : Turkey oil and gas pipelines

    This report presented some quick facts about oil and gas pipelines in Turkey and presented opportunities for trade. The key players and customers in the oil and gas sector were described along with an export check list. Turkey is looking into becoming an energy bridge between oil and gas producing countries in the Middle East, Central Asia and Europe. The oil and gas sectors are dominated by the Turkish Petroleum Corporation, a public enterprise dealing with exploration and production, and the State Pipeline Corporation which deals with energy transmission. They are also the key buyers of oil and gas equipment in Turkey. There are several pipelines connecting countries bordering the Caspian Sea. Opportunities exist in the areas of engineering consulting as well as contracting services for oil and gas pipeline transmission and distribution. Other opportunities lie in the area of pipeline construction, rehabilitation, materials, equipment, installation, and supervisory control and data acquisition (SCADA) systems. Currently, the major players are suppliers from Italy, Germany, France, United States and Japan. Turkey has no trade barriers and imported equipment and materials are not subjected to any restriction. The oil and gas market in Turkey expected in increase by an average annual growth rate of 15 per cent from 2001 to 2003. A brief description of pipeline projects in Turkey was presented in this report along with a list of key contacts and support services. 25 refs., 1 append

  14. Legal briefing: organ donation and allocation.

    Pope, Thaddeus Mason

    2010-01-01

    This issue's "Legal Briefing" column covers legal developments pertaining to organ donation and allocation. This topic has been the subject of recent articles in JCE. Organ donation and allocation have also recently been the subjects of significant public policy attention. In the past several months, legislatures and regulatory agencies across the United States and across the world have changed, or considered changing, the methods for procuring and distributing human organs for transplantation. Currently, in the U.S., more than 100,000 persons are waiting for organ transplantation. In China, more than 1.5 million people are waiting. Given the chronic shortage of available organs (especially kidneys and livers) relative to demand, the primary focus of most legal developments has been on increasing the rate of donation. These and related developments are usefully divided into the following 12 topical categories: 1. Revised Uniform Anatomical Gift Act. 2. Presumed Consent and Opt-Out. 3. Mandated Choice. 4. Donation after Cardiac Death. 5. Payment and Compensation. 6. Donation by Prisoners. 7. Donor Registries. 8. Public Education. 9. Other Procurement Initiatives. 10. Lawsuits and Liability. 11. Trafficking and Tourism. 12. Allocation and Distribution. PMID:21089996

  15. A brief history of mathematics in finance

    Erdinç Akyıldırım

    2014-03-01

    Full Text Available In the list of possible scapegoats for the recent financial crises, mathematics, in particular mathematical finance has been ranked, without a doubt, as the first among many and quants, as mathematicians are known in the industry, have been blamed for developing and using esoteric models which are believed to have caused the deepening of the financial crisis. However, as Lo and Mueller (2010 state “Blaming quantitative models for the crisis seems particularly perverse, and akin to blaming arithmetic and the real number system for accounting fraud.” Throughout the history, mathematics and finance have always been in a close relationship. Starting from Babylonians, through Thales, and then Fibonacci, Pascal, Fermat, Bernoulli, Bachelier, Wiener, Kolmogorov, Ito, Markowitz, Black, Scholes, Merton and many others made huge contributions to the development of mathematics while trying to solve finance problems. In this paper, we present a brief historical perspective on how the development of finance theory has influenced and in turn been influenced by the development of mathematical finance theory.

  18. A brief examination of optical tagging technologies.

    Ackermann, Mark R.; Cahill, Paul A. (Aspecular Optics, Dayton, OH); Drummond, Timothy J.; Wilcoxon, Jess Patrick

    2003-07-01

    Presented within this report are the results of a brief examination of optical tagging technologies funded by the Laboratory Directed Research and Development (LDRD) program at Sandia National Laboratories. The work was performed during the summer months of 2002 with total funding of $65k. The intent of the project was to briefly examine a broad range of approaches to optical tagging concentrating on the wavelength range between ultraviolet (UV) and the short wavelength infrared (SWIR, {lambda} < 2{micro}m). Tagging approaches considered include such things as simple combinations of reflective and absorptive materials closely spaced in wavelength to give a high contrast over a short range of wavelengths, rare-earth oxides in transparent binders to produce a narrow absorption line hyperspectral tag, and fluorescing materials such as phosphors, dies and chemically precipitated particles. One technical approach examined in slightly greater detail was the use of fluorescing nano particles of metals and semiconductor materials. The idea was to embed such nano particles in an oily film or transparent paint binder. When pumped with a SWIR laser such as that produced by laser diodes at {lambda}=1.54{micro}m, the particles would fluoresce at slightly longer wavelengths, thereby giving a unique signal. While it is believed that optical tags are important for military, intelligence and even law enforcement applications, as a business area, tags do not appear to represent a high on return investment. Other government agencies frequently shop for existing or mature tag technologies but rarely are interested enough to pay for development of an untried technical approach. It was hoped that through a relatively small investment of laboratory R&D funds, enough technologies could be identified that a potential customers requirements could be met with a minimum of additional development work. Only time will tell if this proves to be correct.

  19. Legal briefing: conscience clauses and conscientious refusal.

    Pope, Thaddeus Mason

    2010-01-01

    This issue's "Legal Briefing" column covers legal developments pertaining to conscience clauses and conscientious refusal. Not only has this topic been the subject of recent articles in this journal, but it has also been the subject of numerous public and professional discussions. Over the past several months, conscientious refusal disputes have had an unusually high profile not only in courthouses, but also in legislative and regulatory halls across the United States. Healthcare providers' own moral beliefs have been obstructing and are expected to increasingly obstruct patients' access to medical services. For example, some providers, on ethical or moral grounds, have denied: (1) sterilization procedures to pregnant patients, (2) pain medications in end-of-life situations, and (3) information about emergency contraception to rape victims. On the other hand, many healthcare providers have been forced to provide medical treatment that is inconsistent with their moral beliefs. There are two fundamental types of conscientious objection laws. First, there are laws that permit healthcare workers to refuse providing - on ethical, moral, or religious grounds healthcare services that they might otherwise have a legal or employer-mandated obligation to provide. Second, there are laws directed at forcing healthcare workers to provide services to which they might have ethical, moral, or religious objections. Both types of laws are rarely comprehensive, but instead target: (1) certain types of healthcare providers, (2) specific categories of healthcare services, (3) specific patient circumstances, and (4) certain conditions under which a right or obligation is triggered. For the sake of clarity, I have grouped recent legal developments concerning conscientious refusal into eight categories: 1. Abortion: right to refuse 2. Abortion: duty to provide 3. Contraception: right to refuse 4. Contraception: duty to provide 5. Sterilization: right to refuse 6. Fertility, HIV, vaccines

  18. Global Green New Deal. Policy Brief

    The 'Global Green New Deal' (GGND) presented here has three broad objectives. It should make a major contribution to reviving the world economy, saving and creating jobs, and protecting vulnerable groups. It should promote sustainable and inclusive growth and the achievement of the MDGs, especially ending extreme poverty by 2015. Also, it must reduce carbon dependency and ecosystem degradation. These are key risks along a path to a sustainable world economy. Our consultations and our commissioned research, summarized here in this Policy Brief, make a strong case for the active 'greening' of proposed fiscal stimulus packages. However, this must also be backed by necessary changes in international and domestic policy architectures, as the current framework is biased in favour of resurrecting an unsustainable 'brown economy'. Our proposals are therefore grouped under three categories - targeted stimulus spending in 2009-10, changes in domestic policies, and changes in international policy architecture. Furthermore, we recognize that many less developed countries do not have the resources of their own and will have to rely on foreign aid and support, both financial and non-financial. We propose that the fiscal stimulus (to be applied over 2009 and 2010) should prioritize energy efficient buildings and investments in sustainable transport and renewable energy. Developing countries should prioritize investment in agricultural productivity measures, freshwater management, and sanitation, as these have demonstrable and exceptional social returns. Domestic policy reforms are recommended to substantially reduce perverse subsidies (eg: fossil fuels) and instead to create positive incentives and appropriate taxes which will encourage a greener economy. Domestic reforms should also address some common issues in land use and urban policy. Integrated management of freshwater would also require some domestic policy changes, and this should be prioritized by developing countries

  19. Zora’s Politics: A Brief Introduction

    Ernest Julius Mitchell II

    2013-09-01

    Full Text Available In his introduction to reading Zora Neale Hurston’s politics, Mitchell argues that contemporary scholarship has misread Hurston in significant ways, distorting Hurston’s work and reputation to serve contesting political agendas; thus, in recent years, she has been associated with “a bewildering array of affiliations: republican, libertarian, radical democrat, reactionary conservative, black cultural nationalist, anti-authoritarian feminist, and woman-hating protofascist.” Recuperating Hurston from this impossible political melee of labels, Mitchell argues, requires a careful reading of Hurston’s work dating from her earliest pieces in the late 1920s, as well as surveying her many yet to be published manuscripts and letters; it requires recognition of the transnational and comparative lens through which she reported on political maneuvers and military histories, as well as reading not only her strong criticisms but also her silences, ironic phrasings, and nuanced critiques in her writings on global colonial enterprises. Mitchell’s introduction to the two Hurston essays here reprinted, “I Saw Negro Votes Peddled” (1950 and “Why the Negro Won’t Buy Communism” (1951—courtesy of the American Legion Magazine—is set in the larger frame of his assertion that Hurston’s work should be read with a deep appreciation of her staunch anticolonialism. Tracing her political philosophy through her views of how race and religion are used to valorize an international culture of violence that serves imperialistic and colonial ends, Mitchell takes his reader on a tour of Hurston’s transnational commentary—from the US occupation of Haiti, to the Spanish and British on the Florida peninsula; from Communist Russia and China, to election practices in the US—to set the stage for our encounters with these rarely read Hurston essays. Reading Mitchell’s “Zora’s Politics: A Brief Introduction” provides a firm foundation for a more

  20. Engine Development Design Margins Briefing Charts

    Bentz, Chuck

    2006-01-01

    New engines experience durability problems after entering service. The most prevalent and costly is the hot section, particularly the high-pressure turbine. The origin of durability problems can be traced back to: 1) the basic aero-mechanical design systems, assumptions, and design margins used by the engine designers, 2) the available materials systems, and 3) to a large extent, aggressive marketing in a highly competitive environment that pushes engine components beyond the demonstrated capability of the basic technology available for the hardware designs. Unfortunately the user must operate the engine in the service environment in order to learn the actual thrust loading and the time at max effort take-off conditions used in service are needed to determine the hot section life. Several hundred thousand hours of operational service will be required before the demonstrated reliability of a fleet of engines or the design deficiencies of the engine hot section parts can be determined. Also, it may take three to four engine shop visits for heavy maintenance on the gas path hardware to establish cost effective build standards. Spare parts drive the oerator's engine maintenance costs but spare parts also makes lots of money for the engine manufacturer during the service life of an engine. Unless competition prevails for follow-on engine buys, there is really no motivation for an OEM to spend internal money to improve parts durability and reduce earnings derived from a lucrative spare parts business. If the hot section life is below design goals or promised values, the OEM migh argue that the engine is being operated beyond its basic design intent. On the other hand, the airframer and the operator will continue to remind the OEM that his engine was selected based on a lot of promises to deliver spec thrust with little impact on engine service life if higher thrust is used intermittently. In the end, a standoff prevails and nothing gets fixed. This briefing will propose

  1. Brief Behavioral Sleep Intervention for Adolescents: An Effectiveness Study.

    Paavonen, E Juulia; Huurre, Taina; Tilli, Maija; Kiviruusu, Olli; Partonen, Timo

    2016-01-01

    Sleep disturbances are common among adolescents, but there are no brief interventions to treat them. The objective of this study was to evaluate the effectiveness of a brief semistructured, individually delivered sleep intervention to ameliorate adolescents' sleeping difficulties and lengthen sleep duration. All students aged 16-18 years in a high school were screened for sleeping difficulties and 36 students with the highest sleep problem scores were invited to the intervention. Postintervention improvements were observed on self-reported and actiwatch-registered sleep duration, self-reported sleep quality and sleep latency, perceived stress and anxiety (all p values 0.05). A brief individual sleep intervention can be effective in lengthening sleep duration and improving subjective sleep quality and well-being among adolescents. PMID:26378797

  2. Renewable energy. From marginal to mainstream. Policy Brief

    Veum, K.C.; Uslu, A.; De Coninck, H.C. [ECN Policy Studies, Petten (Netherlands)

    2013-04-15

    This policy brief aims to instigate a debate on the broader enabling conditions required to move renewable energy from marginal shares in the European energy system to a mainstream role. It does so by posing seven key questions related to public movement, the political-industrial complex, resources and sustainability, grids and markets, finance, legal procedures and overall policy. These questions require short- to medium-term attention to keep a long-term renewable energy system within the realm of possibilities. This policy brief also provides ECN's initial reflections on how these key questions could be addressed, and indicates which relevant expertise it can bring to the table.

  5. Paroxetine in the treatment of recurrent brief depressive disorder

    Sathya Prakash

    2013-01-01

    Full Text Available Recurrent brief depressive disorder is now a well-recognized type of depressive disorder. However, there is still no clear evidence base for its treatment. The efficacy of several drugs including antidepressants and mood stabilizers in this disorder has been controversial. Methodological limitations need to be considered when interpreting the results of studies on efficacy of drugs in this disorder. We report a case of recurrent brief depressive disorder that responded dramatically to paroxetine. However, there is a need for larger, methodologically sound, double-blind, placebo-controlled studies.
