description: Background: Environmental epidemiology, when focused on the life course of exposure to a specific pollutant, requires historical exposure estimates that are difficult to obtain for the full time period due to gaps in the historical record, especially in earlier years. We show that these gaps can be filled by applying multiple imputation methods to a formal risk equation that incorporates lifetime exposure. We also address challenges that arise, including choice of imputation method, potential bias in regression coefficients, and uncertainty in age-at-exposure sensitivities.
Methods: During time periods when parameters needed in the risk equation are missing for an individual, the parameters are filled by an imputation model using group level information or interpolation. A random component is added to match the variance found in the estimates for study subjects not needing imputation. The process is repeated to obtain multiple data sets, whose regressions against health data can be combined statistically to develop confidence limits using Rubin’s rules to account for the uncertainty introduced by the imputations. To test for possible recall bias between cases and controls, which can occur when historical residence location is obtained by interview, and which can lead to misclassification of imputed exposure by disease status, we introduce an “incompleteness index,” equal to the percentage of dose imputed (PDI) for a subject. “Effective doses” can be computed using different functional dependencies of relative risk on age of exposure, allowing intercomparison of different risk models. To illustrate our approach, we quantify lifetime exposure (dose) from traffic air pollution in an established case–control study on Long Island, New York, where considerable in-migration occurred over a period of many decades. Results: The major result is the described approach to imputation. The illustrative example revealed potential recall bias, suggesting that regressions against health data should be done as a function of PDI to check for consistency of results. The 1% of study subjects who lived for long durations near heavily trafficked intersections, had very high cumulative exposures. Thus, imputation methods must be designed to reproduce non-standard distributions. Conclusions: Our approach meets a number of methodological challenges to extending historical exposure reconstruction over a lifetime and shows promise for environmental epidemiology. Application to assessment of breast cancer risks will be reported in a subsequent manuscript.
Political Circumstances and Political Choices: A Reading of the Fluctuations of Japanese "Modernity" in North American History-Writing, 1940-2000

Subjects: History

description: E. Herbert Norman's Japan's Emergence as a Modern State put into operation the category of "modernity" for North American history-writing about Japan. After 1940, uses of "modernity" existed in tension with relative disuses of the category, and the category itself changed definition. This paper tracks the variable of "modernity" in relation to variables of political circumstances and political choices made by historians starting with the publication of Norman's book and continuing through the publication of Harry Harootunian's Things Seen and Unseen in 1988. It concludes with a brief consideration of scholarship of the 1990s.

description: Using spectral data from non-strange and strange hadronic tau decays, flavor-breaking chiral sum rules involving the flavor ud and us current-current two-point functions are constructed and used to determine the SU(3) NNLO low-energy constant combinations C_{61}^r, C_{12}^r+C_{61}^r+C_{80}^r and C_{12}^r-C_{61}^r+C_{80}^r. The first of these determinations updates the results of an earlier analysis by Durr and Kambor, while the latter two are new. The error on the C_{12}^r+C_{61}^r+C_{80}^r is particularly small. Comparisons are made to model estimates for these quantities. The role of the third combination in significantly improving the determination of the NLO low-energy constant L_{10}^r from NNLO analyses of the flavor ud V-A correlator is also highlighted.

description: The use of DNA microarrays and oligonucleotide chips of high density in modern biomedical research provides complex, high dimensional data which have been proven to convey crucial information about gene expression levels and to play an important role in disease diagnosis. Therefore, there is a need for developing new, robust statistical techniques to analyze these data. Results: depthTools is an R package for a robust statistical analysis of gene expression data, based on an efficient implementation of a feasible notion of depth, the Modified Band Depth. This software includes several visualization and inference tools successfully applied to high dimensional gene expression data. A user-friendly interface is also provided via an R-commander plugin. Conclusion: We illustrate the utility of the depthTools package, that could be used, for instance, to achieve a better understanding of genome-level variation between tumors and to facilitate the development of personalized treatments.

description: This paper presents a household cooling system controller which is adaptive and intelligent in nature. It is able to control the speed of a household cooling fan or an air conditioner based on the real time data namely room temperature, humidity and time i.e. duration, which are collected from environment. To control the speed in an adaptive and intelligent manner an associative memory neural network has been used. This embedded system is able to learn from training set i.e. the user can teach the system about his/her feelings through training data sets. When the system starts up it allows the fan to run freely i.e. at full speed and after certain interval it takes the environmental parameters like room temperature, humidity and time i.e. duration, as an input and after that system takes the decision and controls the speed of the fan.

description: A Bott manifold is the total space of some iterated $\mathbb C P^1$-bundle over a point. We prove that any graded ring isomorphism between the cohomology rings of two Bott manifolds preserves their Pontrjagin classes. Moreover, we prove that such an isomorphism is induced from a diffeomorphism if the Bott manifolds are $\mathbb Z/2$-trivial, where a Bott manifold is called $\mathbb Z/2$-trivial if its cohomology ring with $\mathbb Z/2$-coefficient is isomorphic to that of a product of $\mathbb C P^1$'s.

description: Scopo del presente intervento esposto al 53° Congresso di Senigallia della Società Italiana di Storia della Medicina, è quello di apportare ulteriori elementi alla conoscenza sull’infanzia abbandonata in una realtà locale, ovvero a Siena, nel periodo compreso tra il 1762 e il 1764. La base di ricerca è costituita da alcuni registri della serie “Baliatici” conservati presso l’Archivio di Stato di Siena dove sono riportate, in ordine cronologico, notizie su ogni bambino introdotto nello Spedale di Santa Maria della Scala, destinato all’epoca alla cura dei malati e dei trovatelli, e le retribuzioni corrisposte alle nutrici con le relative spese connesse alla cura dei fanciulli stessi. Su di essi è stata effettuata una rilevazione su un totale di 682 bambini abbandonati dei quali abbiamo individuato nome e cognome, sesso, data e modalità di ingresso, luogo di provenienza, data di decesso o di restituzione ai genitori. Attraverso la costruzione di tabelle, abbiamo rilevato e commentato le caratteristiche dei trovatelli e delle balie a cui erano affidati.

description: We study the symmetries of the post-recombination cosmological magnetohydrodynamical equations which describe the evolution of dark matter, baryons and magnetic fields in a self-consistent way. This is done both at the level of fluid equations and of Vlasov-Poisson-Maxwell equations in phase space. We discuss some consistency relations for the soft limit of the (n + 1)-correlator functions involving magnetic fields and matter overdensities. In particular, we stress that any violation of such consistency relations at equal-time would point towards an inflationary origin of the magnetic field.

description: We assess climate impacts of global warming using ongoing observations and paleoclimate data. We use Earth’s measured energy imbalance, paleoclimate data, and simple representations of the global carbon cycle and temperature to define emission reductions needed to stabilize climate and avoid potentially disastrous impacts on today’s young people, future generations, and nature. A cumulative industrial-era limit of ~500 GtC fossil fuel emissions and 100 GtC storage in the biosphere and soil would keep climate close to the Holocene range to which humanity and other species are adapted. Cumulative emissions of ~1000 GtC, sometimes associated with 2°C global warming, would spur “slow” feedbacks and eventual warming of 3–4°C with disastrous consequences. Rapid emissions reduction is required to restore Earth’s energy balance and avoid ocean heat uptake that would practically guarantee irreversible effects. Continuation of high fossil fuel emissions, given current knowledge of the consequences, would be an act of extraordinary witting intergenerational injustice. Responsible policymaking requires a rising price on carbon emissions that would preclude emissions from most remaining coal and unconventional fossil fuels and phase down emissions from conventional fossil fuels.

description: Background: Adherence to treatment and sputum smear conversion after 2 months of treatment are thought to be important for successful outcome of tuberculosis (TB) treatment. Methods: Retrospective cohort study of new adult TB patients diagnosed in the first quarter of 2007 at 48 clinics in Rwanda. Data were abstracted from TB registers and individual treatment charts. Logistic regression analysis was done to examine associations between baseline demographic and clinical factors and three outcomes adherence, sputum smear conversion at two months, and death. Results: Out of 725 eligible patients the treatment chart was retrieved for 581 (80%). Fifty-six (10%) of these patients took &90% of doses (defined as poor adherence). Baseline demographic characteristics were not associated with adherence to TB treatment, but adherence was lower among HIV patients not taking antiretroviral therapy (ART); p = 0.03). Sputum smear results around 2 months after start of treatment were available for 220 of 311 initially sputum-smear-positive pulmonary TB (PTB+) patients (71%); 175 (80%) had achieved sputum smear conversion. In multivariable analysis, baseline sputum smear grade (odds ratio [OR] = 2.7, 95% Confidence interval [CI] 1.1–6.6 comparing smear 3+ against 1+) and HIV infection (OR 3.0, 95%CI 1.3–6.7) were independent predictors for non-conversion at 2 months. Sixty-nine of 574 patients (12%) with known TB treatment outcomes had died. Besides other known determinants, poor adherence had an independent, strong effect on mortality (OR 3.4, 95%CI 1.4–7.8). Conclusion: HIV infection is an important independent predictor of failure of sputum smear conversion at 2 months among PTB+ patients. Poor adherence to TB treatment is an important independent determinant of mortality.

description: It is known that diabetes can not be cured completely, but it can be controlled. The objective of this work is to provide an automatic system that will be able to help the diabetic patient to control the blood sugar. This system measures the blood sugar level of the people from their urine round-the-clock. A recorded message based on this input may be displayed so that apart from patient himself others can be informed about his/her present sugar level. That should help him/her in taking medicine; controlling diet etc. This work is an application of image processing and fuzzy logic. It is known that Benedict's reagent changes its colour based on the sugar level. This colour change information is sensed by the transducer and fed to the fuzzy logic unit for decision making.

description: In Ref. [1] we presented the JIMWLK Hamiltonian for high energy evolution of QCD amplitudes at the next-to-leading order accuracy in $α_s$. In the present paper we provide details of our original derivation, which was not reported in [1], and provide the Hamiltonian in the form appropriate for action on color singlet as well as color nonsinglet states. The rapidity evolution of the quark dipole generated by this Hamiltonian is computed and compared with the corresponding result of Balitsky and Chirilli [2]. We then establish the equivalence between the NLO JIMWLK Hamiltonian and the NLO version of the Balitsky's hierarchy [3], which includes action on nonsinglet combinations of Wilson lines. Finally, we present complete evolution equation for three-quark Wilson loop operator, thus extending the results of Grabovsky [4].

description: Recent developments in path integral methodology have significantly reduced the computational expense of including quantum mechanical effects in the nuclear motion in ab initio molecular dynamics simulations. However, the implementation of these developments requires a considerable programming effort, which has hindered their adoption. Here we describe i-PI, an interface written in Python that has been designed to minimise the effort required to bring state-of-the-art path integral techniques to an electronic structure program. While it is best suited to first principles calculations and path integral molecular dynamics, i-PI can also be used to perform classical molecular dynamics simulations, and can just as easily be interfaced with an empirical forcefield code. To give just one example of the many potential applications of the interface, we use it in conjunction with the CP2K electronic structure package to showcase the importance of nuclear quantum effects in high pressure water.

description: We study the propagation of stress waves through ordered 2D networks of granular chains. The quasi-particle continuum theory employed captures the acoustic pulse splitting, bending, and recombination through the network and is used to derive its effective acoustic properties. The strong wave mitigation properties of the network predicted theoretically are confirmed through both numerical simulations and experimental tests. In particular, the leading pulse amplitude propagating through the system is shown to decay exponentially with the propagation distance and the spatial structure of the transmitted wave shows an exponential localization along the direction of the incident wave. The length scales that characterized these exponential decays are studied and determined as a function of the geometrical properties of the network. These results open avenues for the design of efficient impact mitigating structures and provide new insights into the mechanisms of wave propagation in granular matter.

Optimal Monetary and Fiscal Policy: A Linear-Quadratic Approach

Subjects: Economics
Public policy (Law)

description: From pages 271-272 -- 'While substantial research literatures seek to characterize optimal monetary and fiscal policy, respectively, the two branches of the literature have largely developed in isolation, and on apparently contradictory foundations. The modern literature on dynamically optimal fiscal policy often abstracts from monetary aspects of the economy altogether and so implicitly allows no useful role for monetary policy. When monetary policy is considered within the theory of optimal fiscal policy, it is most often in the context of models with flexible prices. In these models, monetary policy matters only because (1) the level of nominal interest rates (and hence the opportunity cost of holding money) determines the size of certain distortions that result from the attempt to economize on money balances, and (2) the way the price level varies in response to real disturbances determines the state-contingent real payoffs on (riskless) nominally denominated government debt, which may facilitate tax-smoothing in the case the explicitly state-contingent debt is not available. The literature on optimal monetary policy has instead been mainly concerned with quite distinct objectives for monetary stabilization policy, namely, the minimization of the distortions that result from prices or wages that do not adjust quickly enough to clear markets. At the same time, this literature typically ignores the fiscal consequences of alternative monetary policies; the characterizations of optimal monetary policy obtained are thus strictly correct only for a world in which lump-sum taxes are available.
Here we wish to consider the way in which the conclusions reached in each of these two familiar fields of study must be modified if one takes simultaneous account of the basic elements of the policy problems addressed in each. On the one hand, we wish to consider how conventional conclusions with regard to the nature of an optimal monetary policy rule must be modified if one recognizes that the government's only sources of revenue are distorting taxes, so that the fiscal consequences of monetary policy matter for welfare. And, on the other hand, we wish to consider how conventional conclusions with regard to optimal tax policy must be modified if one recognizes that prices do not instantaneously clear markets, so that output determination depends on aggregate demand, in addition to the supply-side factors stressed in the conventional theory of optimal taxation.'

description: It is known that the emission rate of entropy from a Schwarzschild black hole is exactly the same as that of a one dimensional quantum channel \cite{Beken}. We calculate the dimension of entropy emission from a $D$ dimensional pure Lovelock black holes. Our results indicate that the dimension of transmission for odd $D$ dimensional space-times is equal to $D$ and for even $D$ dimensional space-times, the dimension of quantum channel becomes $1+ε(Λ)$, where $ Λ$ is cosmological constant. It is interesting that cosmological constant may put some constraint on dimension of quantum channel in even dimensional space-times. The effect of Generalized Uncertainty Principle (GUP) on the dimension of transmission of entropy for a Schwarzschild black hole is also investigated.

description: Pemecahan masalah merupakan merupakan salah satu aspek utama dalam kurikulum matematika yang dibutuhkan siswa untuk menerapkan dan mengintegrasikan banyak konsep dan keterampilan matematika serta membuat keputusan yang sangat penting untuk pengembangan pemahaman konseptual. Kenyataannya, pembelajaran matematika di sekolah selama ini ku-rang memberikan kesempatan kepada siswa untuk mengembangkan kemampuannya dalam memecahkan masalah. Guru tidak membiasakan siswa untuk melatih melakukan pemecahan masalah ketika proses pembelajaran sehingga rata-rata persentase kemampuan pemecahan masalah termasuk kedalam kategori rendah. Rendahnya kemampuan pemecahan masalah ma-tematika membutuhkan adanya inovasi dalam pembelajaran matematika, salah satunya dengan menggunakan model pembelajaran Problem Posing and Solving (PPS). Model pembelajaran PPS pada intinya memungkinkan siswa menghubungkan pengetahuannya dengan pengalaman mereka, mengajarkan berpikir secara analitis dengan menghubungkan konsep dunia nyata sehingga menghasilkan pemahaman konseptual yang lebih baik dan pada akhirnya mengembangkan kemampuan pemecahan masalah serta memotivasi mereka untuk belajar. Penelitian ini adalah penelitian quasi exprimental design yang bertujuan untuk mengetahui efektifitas model pembelajaran PPS (Problem Posing and Solving) terhadap kemampuan pemecahan masalah Matematika pada siswa. Dari hasil pengujian hipotesis dengan uji independent sample t-test diperoleh nilai t hitung p < α (0,005 < 0,05) dan hasil uji effect size dengan
skor sebesar 0,801 (Kategori efek besar) serta nilai peningkatan (gain) rata-rata sebesar

description: We investigate the spatial and temporal structures of four financial markets in Greater China. In particular, we uncover different characteristics of the four markets by analyzing the sector and subsector structures which are detected through the random matrix theory. Meanwhile, we observe that the Taiwan and Hongkong stock markets show a negative return-volatility correlation, i.e., the so-called leverage effect. The Shanghai and Shenzhen stock markets are more complicated. Before the year 2000, the two markets exhibit a strong positive return-volatility correlation, which is called the anti-leverage effect. After 2000, however, it gradually changes to the leverage effect. We also find that the recurrence interval distributions of both the trading volume volatilities and price volatilities follow a power law behavior, while the exponents vary among different markets.

description: Astroparticles offer a new path for research in the field of particle physics, allowing investigations at energies above those accesible with accelerators. Ultra-high energy cosmic rays can be studied via the observation of the showers they generate in the atmosphere. The Pierre Auger Observatory is a hybrid detector for ultra-high energy cosmic rays, combining two complementary measurement techniques used by previous experiments, to get the best possible measurements of these air showers. Shower observations enable one to not only estimate the energy, direction and most probable mass of the primary cosmic particles but also to obtain some information about the properties of their hadronic interactions. Results that are most relevant in the context of determining hadronic interaction characteristics at ultra-high energies will be presented.

title: Efficient Cryptographic Constructions with Strong Security Guarantees
Creators: name: Kurek, Rafael
Publisher: name: Bergische Universität Wuppertal

description: Digital devices, systems, and networks effect more and more parts of everyday life. However, due to the complexity of modern digital technology a variety of techniques and mechanisms are required in order to secure communication and to protect sensitive data. The science dealing with secure communication and data protection is called cryptography. This thesis bridges the gap between cryptographic constructions with strong security guarantees and efficient execution. Here, strong security mainly refers to security against adaptive adversaries. For instance, this may refer to several kinds of queries which depend on the respond to previous queries as well as corrupting machines depending on prior corruptions. Efficiency refers to improvements in speed and savings in space. Those are achieved by lower computational costs, fewer communication rounds or smaller elements like keys, ciphertexts, and digital signatures.
An Optimization-Based Econometric Framework for the Evaluation of Monetary Policy: Expanded Version

description: This paper considers a simple quantitative model of output, interest rate and inflation determination in the United States, and uses it to evaluate alternative rules by which the Fed may set interest rates. The model is derived from optimizing behavior under rational expectations, both on the part of the purchasers of goods and upon that of the sellers. The model matches the estimated responses to a monetary policy shock quite well and, once due account is taken of other disturbances, can account for our data nearly as well as an unrestricted VAR. The monetary policy rule that most reduces inflation variability (and is best on this account) requires very variable interest rates, which in turn is possible only in the case of a high average inflation rate. But even in the case of a constrained-optimal policy, that takes into account some of the costs of average inflation and constrains the variability of interest rates so as to keep average inflation low, inflation would be stabilized considerably more and output stabilized considerably less than under out estimates of current policy. Moreover, this constrained-optimal policy also allows average inflation to be much smaller.
This version contains additional details of our derivations and calculations, including three technical appendices, not included in the version published in NBER Macroeconomics Annual 1997.

description: The challenge of the young generation today at the national Independence Day ceremony is to understand its connection totheir current lives as a digital generation. This study aims to use an immersive virtual reality game to entertain and educatethe importance of the Tanzanian Independence Day ceremonies among the current youths in the digital era. These ceremonies connote the historical timeline in the nation’s struggle; furthermore, they can serve the meaning to the young generation in global citizenship, social interactions, human equality, and democracy. Independence deserves serious attention in enlightening the youths on the importance and respect of using digital tools, interactions in the cyber world,also guiding them to become better digital citizens, and the importance of environmental conservation. Using an immersiveand interactive storytelling experience, with a specific set of Tanzanian scenarios, the player explores immersive scenes,from the current modern living room to historical scenes with different interaction modes (passive and active), that willtrigger questions and answers, to the player within story structures. Tanzania like many African countries in the 60s got itsindependence in 1961, which makes it difficult for the youths of today to connect with their current lives. Afterward, the player will complete a standardized questionnaire, regarding their sense of presence, cognitive interest, and engagement during the game. By playing this game, the young generation may gain cognitive interests on their national Independence Day, learn about geographical nature, and understand the importance of interacting as digital citizens. In addition, they feela presence when they navigate freely through the game. The use of this implicitly structured VR game may increase spatialinformation and several interesting edutainments environments. This immersive virtual interacted environment system wascreated by Unity and then build for several devices including mobile phones, websites, head-mounted displays (HMD), andVR sets.
Dynamical properties of three terminal magnetic tunnel junctions: spintronics meets spin-orbitronics

description: This letter introduces a micromagnetic model able to characterize the magnetization dynamics in three terminal magnetic tunnel junctions, where the effects of spin-transfer torque and spin-orbit torque are taken into account. Our results predict that the possibility to separate electrically those two torque sources is very promising from a technological point of view for both next generation of nanoscale spintronic oscillators and microwave detectors. A scalable synchronization scheme based on the parallel connection of those three terminal devices is also proposed.

description: From page 63 -- 'Perfectly competitive models of the effects of aggregate demand variations on output and employment have great difficulty generating patterns of comovement among aggregate variables that resemble typical 'business cycle' patterns (Barro and King, 1984). We wish to emphasize two such difficulties here, and to argue that an imperfectly competitive model of product markets can avoid these difficulties.'

description: The regular number of a graph G denoted by reg(G) is the minimum number of subsets into which the edge set of G can be partitioned so that the subgraph induced by each subset is regular. In this work we answer to the problem posed as an open problem in A. Ganesan et al. (2012) [3] about the complexity of determining the regular number of graphs. We show that computation of the regular number for connected bipartite graphs is NP-hard. Furthermore, we show that, determining whether reg(G) = 2 for a given connected 3-colorable graph G is NP-complete. Also, we prove that a new variant of the Monotone Not-All-Equal 3-Sat problem is NP-complete.

Optimal Inflation Targeting under Alternative Fiscal Regimes

description: Standard discussions of flexible inflation targeting as an optimal monetary policy abstract completely from the consequences of monetary policy for the government budget. But at least some of the countries now adopting inflation targeting have substantial difficulty in controlling fiscal imbalances, so that the additional strains resulting from strict control of inflation are of substantial concern, and some (notably Sims 2005) have argued that inflation targeting can even be counterproductive under some fiscal regimes. Here, therefore, we analyze welfare-maximizing monetary policy taking explicit account of the consequences of monetary policy for the government budget, and under a variety of assumptions about the nature of the fiscal regime.

The paper contrasts the optimal monetary policies under three alternative assumptions about fiscal policy: (i) the case in which little distortion is required to raise additional government revenue, and the fiscal authority can be relied upon to ensure intertemporal government solvency [the implicit assumption in standard analyses]; (ii) the case in which only distorting sources of revenue exist, but distorting taxes are adjusted optimally; and (iii) the case in which tax rates cannot be expected to change in response to a change in monetary policy [the problematic case emphasized by Sims]. In both of cases (ii) and (iii), it is optimal for monetary policy to allow the inflation rate to respond to fiscal developments (and the optimal responses to other shocks are somewhat different than in the classic analysis, which assumes case (I)). Nonetheless, optimal monetary policy can still be implemented through a form of flexible inflation targeting, and it remains critical, even in the most pessimistic case (case (iii)), that inflation expectations (beyond some very short horizon) not be allowed to vary in response to shocks.
