description: We present a search for the decays B0 --> e+e-, B0 --> mu+ mu- and B0 --> e mu using data collected with the BABAR detector at the PEP-II e+e-collider at SLAC. Using a dataset corresponding to 384 x 10^6 BBbar pairs, we do not find evidence of any of the three decay modes. We obtain upper limit on the branching fractions, at 90% confidence level, of B(B0 --> e+e-)< 11.3 x 10^{-8}, B(B0 --> mu+ mu-) < 5.2 x 10^{-8}, and B(B0 --> e mu) < 9.2 x 10^{-8}.

description: Dark energy is modelled by a Bose-Einstein gas of particles with an attractive interaction. It is coupled to cold dark matter, within a flat universe, for the late-expansion description, producing variations in particle-number densities. The model's parameters, and physical association, are: $Ω_{G0}$, $Ω_{m0}$, the dark-energy rest-mass energy density and the dark-matter term scaling as a mass term, respectively; $Ω_{i0}$, the self-interaction intensity; $x$, the energy exchange rate. Energy conservation relates such parameters. The Hubble equation omits $Ω_{G0}$, but also contains $h$, the present-day expansion rate of the flat Friedman--Lemâitre--Robertson--Walker metric, and $Ω_{b0}$, the baryon energy density, used as a prior. This results in the four effective chosen parameters $Ω_{b0}$, $h$, $Ω_{m0}$, $Ω_{i0}$, fit with the Hubble expansion rate $H(z)$, and data from its value today, near distance, and supernovas. We derive wide $1σ$ and $2σ$ likelihood regions compatible with definite positive total CDM and IBEG mass terms. Additionally, the best-fit value of parameter $x$ relieves the coincidence problem, and a second potential coincidence problem related to the choice of $Ω_{G0}$.

description: We discuss the relation between remnant fragmentation in inelastic high-energy hadronic interactions and muon production in extensive cosmic ray air showers. Using a newly developed tool, a simple and flexible hadronic event generator, we analyze the forward region of hadronic interactions. We show that measurements of the Feynman-x distribution in the beam fragmentation region at LHCf will be key to understanding muon production in air showers quantitatively.

description: In inboard-limited plasmas, foreseen to be used in future fusion reactors start-up and ramp down phases, the Scrape-Off Layer (SOL) exhibits two regions: the "near" and "far" SOL. The steep radial gradient of the parallel heat flux associated with the near SOL can result in excessive thermal loads onto the solid surfaces, damaging them and/or limiting the operational space of a fusion reactor. In this article, leveraging the results presented in [F. Nespoli et al., Nuclear Fusion 2017], we propose a technique for the mitigation and suppression of the near SOL heat flux feature by impurity seeding. First successful experimental results from the TCV tokamak are presented and discussed.

description: It takes millions of years for dead organisms to get converted into fuels. Continues usage of these fuels is the major concern of these fuels are fast depleting. BioCNG is the purified form of biogas, where all the unwanted gases are removed to produce (>95%) pure methane gas. BioCNG is exactly similar to the commercially available natural gas. In India, we lack fuel resources, so we are dependent on fuel rich countries. Today there is a burning need of an alternative for fossil fuels because the fossil fuels are getting extinct. Hence it is necessary to find out alternative source of energy. This topic will make us aware that press mud as well as spent wash which are a waste of sugarcane industries and distilleries can be used to produce biogas. In order to produce biogas from press mud and spent wash, press mud and spent wash is allowed to ferment anaerobically in a digester for 30-40 days at a temperature of 34-38 ̊C. The biogas produced from this process is further up graded and hydrogen sulphide and carbon dioxide are removed so that the end product will have more than 90% - 95% methane which will be used as BioCNG.

Iterative Rounding for Multi-Objective Optimization Problems

description: In this paper we show that iterative rounding is a powerful and flexible tool in the design of approximation algorithms for multi-objective optimization problems. We illustrate that by considering the multi-objective versions of three basic optimization problems: spanning tree, matroid basis and matching in bipartite graphs. Here, besides the standard weight function, we are given k length functions with corresponding budgets. The goal is finding a feasible solution of maximum weight and such that, for all i, the ith length of the solution does not exceed the ith budget. For these problems we present polynomial-time approximation schemes that, for any constant ε> 0 and k ≥ 1, compute a solution violating each budget constraint at most by a factor (1 + ε). The weight of the solution is optimal for the first two problems, and (1 − ε)-approximate for the last one.

description: We present a detailed X-ray timing analysis of the highly variable NLS1 galaxy, IRAS 13224-3809. The source was recently monitored for 1.5 Ms with XMM-Newton which, combined with 500 ks archival data, makes this the best studied NLS1 galaxy in X-rays to date. We apply standard time- and Fourier-domain in order to understand the underlying variability process. The source flux is not distributed lognormally, as would be expected for accreting sources. The first non-linear rms-flux relation for any accreting source in any waveband is found, with $\mathrm{rms} \propto \mathrm{flux}^{2/3}$. The light curves exhibit significant strong non-stationarity, in addition to that caused by the rms-flux relation, and are fractionally more variable at lower source flux. The power spectrum is estimated down to $\sim 10^{-7}$ Hz and consists of multiple peaked components: a low-frequency break at $\sim 10^{-5}$ Hz, with slope $α< 1$ down to low frequencies; an additional component breaking at $\sim 10^{-3}$ Hz. Using the high-frequency break we estimate the black hole mass $M_\mathrm{BH} = [0.5-2] \times 10^{6} M_{\odot}$, and mass accretion rate in Eddington units, $\dot m_{\rm Edd} \gtrsim 1$. The non-stationarity is manifest in the PSD with the normalisation of the peaked components increasing with decreasing source flux, as well as the low-frequency peak moving to higher frequencies. We also detect a narrow coherent feature in the soft band PSD at $0.7$ mHz, modelled with a Lorentzian the feature has $Q \sim 8$ and an $\mathrm{rms} \sim 3$ %. We discuss the implication of these results for accretion of matter onto black holes.

description: A striking characteristic of economic policymaking in this country is our fascination with the ephemeral and our neglect of long-range problems. A lot of passionate commentary, for example, has been devoted to the slowing of the growth rate of real G.N.P. to 3.8 percent in the third quarter. Yet if the past is any guide, that figure, when finally revised, will turn out to have been in error. The slowdown may have been much smaller than reported, and quarterly fluctuations in the growth rate are in any case largely beyond our control. The U.S. economy does not respond like a yo-yo to every push or pull on the string called economic policy.

description: Η παρούσα διπλωματική εργασία έχει ως αντικείμενο τη μελέτη του οικισμού της Καρδάμαινας, στην Κω. Σκοπός της είναι η πολεοδομική οργάνωση της περιοχής με στόχο την αναβάθμιση και τη δημιουργία ενός βιώσιμου και λειτουργικού οικισμού, λαμβάνοντας πάντα υπόψιν τις ιδιαιτερότητες και τις ανάγκες της περιοχής. Η εργασία διαρθρώνεται σε τρεις ενότητες. Στην πρώτη εξ αυτών, έπειτα από επιτόπια καταγραφή, γίνεται η ανάλυση του οικισμού, μελετώντας τις υφιστάμενες χρήσεις γης, την κυκλοφορία, τους ελεύθερους δημόσιους χώρους και τους πραγματοποιημένους όρους δόμησης. Στη δεύτερη ενότητα γίνεται η αξιολόγηση της υφιστάμενης κατάστασης, όπως αυτή προέκυψε από την ανάλυση και τους κατοίκους, μέσω ερωτηματολογίων που μοιράστηκαν δια ζώσης και ηλεκτρονικά. Στην τρίτη ενότητα περιγράφονται οι προτεινόμενες διορθωτικές επεμβάσεις του πολεοδομικού ιστού που κρίθηκαν απαραίτητες στους τέσσερις προαναφερθέντες τομείς, μετά την αξιολόγηση της υφιστάμενης κατάστασης, ενώ παράλληλα προτείνεται και ένα τμήμα επέκτασης, ακολουθώντας τις ίδιες σχεδιαστικές αρχές.
description: The present thesis is the study of the settlement of Kardamena, in Kos. Its purpose is the urban planning of the area aiming to upgrade and create a sustainable and functional settlement, by taking into consideration the characteristics and needs of the area. The thesis is structured in three chapters. In the first one, the analysis of the settlement is conducted, after an on-site inspection, studying the existing land uses, the traffic, the public spaces and the implemented building regulations. In the second chapter, the evaluation of the existing situation is conducted, as derived from the analysis and the residents, through questionnaires distributed in person and electronically. The third section describes the proposed corrective urban fabric interventions that were deemed necessary in the four above-mentioned areas, following the evaluation of the existing situation, while an expansion is also proposed, following the same planning principles.

description: Continuous manufacturing and development of flow processes depend significantly on an optimized and adapted determination of thermokinetic data of chemical reactions. Reaction calorimetry represents a prominent technique to quantify the heat release of exothermic reactions. This work presents a continuous flow calorimetric measurement system based on a commercially available hastelloy C-22 microreactor. A sensor array of Peltier elements is added to the existing microreactor setup to enable the additional functionality of flow calorimetry. The calorimeter and its additional equipment are connected to open-source soft- and hardware for data acquisition and processing as well as automated reaction screening. The reaction calorimeter can be operated in both isoperibolic and isothermal operation mode. The calorimeter's performance is investigated on the basis of model reactions, where good agreement with literature was obtained for determined reaction enthalpies.

The false positive risk: a proposal concerning what to do about p values
Creators: name: Colquhoun, David
Publisher: name: arXiv
Year: 2018
Subjects: subject: Applications (stat.AP)
subject: FOS: Computer and information sciences

description: It is widely acknowledged that the biomedical literature suffer from a surfeit of false positive results. Part of the reason for this is the persistence of the myth that observation of a p value less than 0.05 is sufficient justification to claim that you've made a discovery. It is hopeless to expect users to change their reliance on p values unless they are offered an alternative way of judging the reliability of their conclusions. If the alternative method is to have a chance of being adopted widely, it will have to be easy to understand and to calculate. One such proposal is based on calculation of false positive risk. It is suggested that p values and confidence intervals should continue to be given, but that they should be supplemented by a single additional number that conveys the strength of the evidence better than the p value. This number could be the minimum false positive risk (that calculated on the assumption of a prior probability of 0.5, the largest value that can be assumed in the absence of hard prior data). Alternatively one could specify the prior probability that it would be necessary to believe in order to achieve a false positive risk of, say, 0.05.

description: The intensive synchrotron radiation resulting from quarks interacting with the collective confining color field in relativistic heavy ion collisions is discussed. The spectrum of photons with large transverse momentum is calculated and compared with the experimental data to demonstrate the feasibility of this type of radiation. A study of the earlier predicted azimuthal anisotropy in the angular distribution of dileptons with respect to the three-momentum of the pair is performed as well. This boundary-induced mechanism of lepton pair production is shown to possess the features that are distinctly different from the standard mechanisms and can potentially provide an efficient probe of quark-gluon plasma formation.

description: We address the nonlinear inverse source problem of identifying a time-dependent source occurring in one node of a network governed by a wave equation. We prove that time records of the associated state taken at a strategic set of two nodes yield uniqueness of the two unknown elements: the source position and the emitted signal. We develop a non-iterative identification method that localizes the source node by solving a set of well posed linear systems. Once the source node is localized, we identify the emitted signal using a deconvolution problem or a Fourier expansion. Numerical experiments on a $5$ node graph confirm the effectiveness of the approach.

Taking the possible sensitivity, $R \simeq 10^{-16}$, we obtain the constraint on the Higgs-muon-electron vertex, $κ_{μe}$, to be less than $2.4\times10^{-7}$ if the masses of the Higgs scalar and $W$ gauge boson are the same. $κ_{μe}$ is also calculated for some models.

description: Die Flexibilität der elektrischen Leistung ist eine wesentliche Eigenschaft elektrischer Energiesysteme, die zum Ausgleich absehbarer oder unvorhergesehener Schwankungen von Stromerzeugung und -verbrauch benötigt wird. Durch den steigenden Anteil Erneuerbarer Energien an der Stromerzeugung entsteht somit auch ein erhöhter Bedarf an betrieblicher Flexibilität. Zeitgleich sorgt der Rückbau konventioneller Kraftwerke zu einem verminderten Flexibilitätsangebot, wodurch zukünftig die Erschließung neuer Quellen betrieblicher Flexibilität notwendig wird. Neben weiteren Technologien stellen dezentrale Flexibilitätsoptionen eine aussichtsreiche Flexibilitätsquelle dar. Im Rahmen dieser Arbeit wird zunächst gezeigt, wie sich die nutzbare Flexibilität dezentraler Technologien er-mitteln lässt. Anhand eines Simulationsszenarios für das Energiesystem im Jahr 2035 kann anschließend demonstriert werden, welchen Beitrag diese zum Aus-gleich einer zunehmend fluktuierenden Stromerzeugung leisten können. Der flexible Betrieb dieser Anlagen bewirkt jedoch auch eine signifikante Veränderung der Leistungsflüsse im Verteilnetz. Im zweiten Teil dieser Arbeit wird daher untersucht, welche Wechselwirkungen zwischen der Nutzung von Flexibilitätsoptionen und der Belastungssituation der Verteilnetze besteht.

subject: FOS: Economics and business

description: There are two distinct ways of interpreting the question that serves as a title for this session. On one interpretation, the question asks whether recent advances in the theories of growth and money include the development of a set of necessary and sufficient conditions for an optimum. Although I shall comment briefly on the implications of theoretical work at this level of abstraction, the second interpretation of the question interests me more. On that interpretation, the title asks whether the conclusions of the analysis are applicable, perhaps with minor change, to a money using economy. I shall discuss only one aspect of this question, whether the analysis recognizes the essential difference between a monetary and non-monetary economy. This is a very basic question as Bob Clower has reminded us on this and several other occasions.

description: We study the production of three gauge bosons at the next generation of linear $e^+e^-$ colliders operating in the $γγ$ mode. The processes $γγ\rightarrow W^+W^-V$ ($V=Z^0$, or $γ$) can provide direct information about the quartic gauge-boson couplings. We analyze the total cross section as well as several dynamical distributions of the final state particles including the effect of kinematical cuts. We find out that a linear $e^+e^-$ machine operating in the $γγ$ mode will produce 5--10 times more three-gauge-boson states compared to the standard $e^+e^-$ mode at high energies.

description: Synthesis platforms are of particular interest to DNA-encoded library (DEL) technologies to facilitate chemistry development, building block validation, and high-throughput library synthesis. A liquid–liquid two-phase flow reactor was designed that enables parallel conduction of reactions on DNA-coupled substrates. The dispersed phase in capillary slug flow contained the DNA reaction mixture and allowed for spatially separated batch experiments in a microchannel. A coiled flow inverter (CFI) tubular reactor with a 3D-printed internal structure on which a capillary is coiled was used for improved mixing and compact setup. An inert continuous phase was introduced, which generated slug flow and prevented backmixing of the individual reactants. In order to enable parallelized reactions, slugs containing a variety of different carboxylic acids were successfully generated to act as individual reaction compartments representing single batch experiments. As a widely used exemplary DEL reaction, the amide coupling reaction was successfully transferred to the tailored flow reaction system and DNA was recovered.

description: CONTEXT:At low redshift, early-type galaxies often exhibit a rising flux with decreasing wavelength in the 1000-2500 Å range, called "UV upturn". The origin of this phenomenon is debated, and its evolution with redshift is poorly constrained. The observed GALEX FUV-NUV color can be used to probe the UV upturn approximately to redshift 0.5. AIMS: We provide constraints on the existence of the UV upturn up to redshift $\sim$ 0.4 in the brightest cluster galaxies (BCG) located behind the Virgo cluster, using data from the GUViCS survey. METHODS:We estimate the GALEX far-UV (FUV) and near-UV (NUV) observed magnitudes for BCGs from the maxBCG catalog in the GUViCS fields. We increase the number of nonlocal galaxies identified as BCGs with GALEX photometry from a few tens of galaxies to 166 (64 when restricting this sample to relatively small error bars). We also estimate a central color within a 20 arcsec aperture. By using the $r$-band luminosity from the maxBCG catalog, we can separate blue FUV-NUV due to recent star formation and candidate upturn cases. We use Lick indices to verify their similarity to redshift 0 upturn cases. RESULTS: We clearly detect a population of blue FUV-NUV BCGs in the redshift range 0.10-0.35, vastly improving the existing constraints at these epochs by increasing the number of galaxies studied, and by exploring a redshift range with no previous data (beyond 0.2), spanning one more Gyr in the past. These galaxies bring new constraints that can help distinguish between assumptions concerning the stellar populations causing the UV upturn phenomenon. The existence of a large number of UV upturns around redshift 0.25 favors the existence of a binary channel among the sources proposed in the literature.

description: Solitonic objects play a central role in gauge and string theory (as, e.g., monopoles, black holes, D-branes, etc.). Certain string backgrounds produce a noncommutative deformation of the low-energy effective field theory, which allows for new types of solitonic solutions. I present the construction, moduli spaces and dynamics of Moyal-deformed solitons, exemplified in the 2+1 dimensional Yang-Mills-Higgs theory and its Bogomolny system, which is gauge-fixed to an integrable chiral sigma model (the Ward model). Noncommutative solitons for various 1+1 dimensional integrable systems (such as sine-Gordon) easily follow by dimensional and algebraic reduction. Supersymmetric extensions exist as well and are related to twistor string theory.

description: The growing impact of regulations on the economy has led both Congress and the Administration to search for new ways of reforming the regulatory process. Many of these initiatives call for greater reliance on the use of economic analysis in the development and evaluation of regulations One specific approach being advocated is benefit- cost analysis, an economic tool for comparing the desirable and undesirable impacts of proposed policies.

description: In this work we extend and apply a previous proposal to study noncommutative cosmology to the FRW cosmological background coupled to a scalar field, this is done in classical and quantum scenarios. In both cases noncommutativity is introduced in the gravitational field as well as in the scalar field through a deformation of minisuperspace and are able to find exact solutions. Finally, the effects of noncommutativity on the classical evolution are analyzed.

description: In coupled calculations with Monte Carlo neutronics and thermal hydraulics the Monte Carlo code is used to produce a power distribution which in practice means tallying the energy deposition. Usually the energy deposition is estimated by making a simple approximation that energy is deposited only in fission reactions. The goal of this work is to study how the accuracy of energy deposition modelling affects the results of steady state coupled calculations. For this task an internal coupling between Monte Carlo transport code Serpent 2 and subchannel code SUBCHANFLOW is used along with a recently implemented energy deposition treatment of Serpent 2. The new treatment offers four energy deposition modes each of which offers a different combination of accuracy and required computational time. As a test case, a 3D PWR fuel assembly is modelled with different energy deposition modes. The resulting effective multiplication factors are within 30 pcm. Differences of up to 100K are observed in the fuel temperatures.

description: A deformed Schwarzschild solution in noncommutative gauge theory of gravitation is obtained. The gauge potentials (tetrad fields) are determined up to the second order in the noncommutativity parameters $Θ^{μν}$. A deformed real metric is defined and its components are obtained. The noncommutativity correction to the red shift test of General Relativity is calculated and it is concluded that the correction is too small to have observable effects. Implications of such a deformed Schwarzschild metric are also mentioned.

Is There “Too Much” Inequality in Health Spending Across Income Groups?

description: In this paper we study, from a normative perspective, how society should allocate health resources across individuals. We focus on the relation between health resources and income (taken as a proxy for productivity). In particular we determine the efficient level of the health care social safety net for the indigent. We assume that individuals have different life cycle profiles of productivity. Health care increases survival probability. We adopt the classical approach of welfare economics by considering how a central planner with an egalitarian (ex-ante) perspective would allocate resources. We show that spending should be increasing in productivity, but only during the working years. Post retirement, everyone should get the same health care. Quantitatively, we find that the amount of inequality across the income distribution in the data is larger that what would be justified solely on the basis of production efficiency, but not drastically so. As a rough summary, in U.S. data top to bottom spending ratios are about 1.5 for most of the life cycle. Efficiency implies a decline from about 2 (at age 25) to 1 at retirement. We find larger inefficiencies in the lower part of the income distribution and in post retirement ages.
Modular enhancement of circularly polarized luminescence in Pd2A2B2 heteroleptic cages

description: Metal-mediated assembly allows us to combine an achiral emissive ligand A with different chiral ligands (such as B) in a non-statistical fashion, obtaining Pd2A2B2 heteroleptic cages showing circularly polarized luminescence (CPL). By using the ‘shape complementary assembly’ (SCA) strategy, the cages are exclusively obtained as cis-Pd2A2B2 stereoisomers, as confirmed by NMR, MS and DFT analyses. Their unique chiroptical properties derive from the synergy of all the building blocks. Ligand B imparts the chiral information of its aliphatic backbone, comprising two stereogenic sp3 carbon centres, to the overall structure, causing CD and CPL signal induction for the chromophore on ligand A. The heteroleptic cage shows CPL with a |glum| value of 2.5 × 10−3, which is 3-times higher than that for a progenitor based on aromatic helical building block H, thus opening a rational route towards optimizing the CPL properties of self-assembled nanostructures in a modular way.

description: Cosmological time crystals are created when a scalar field moves periodically through phase space in a spatially flat Friedmann-Robertson-Walker spacetime due to the presence of a limit cycle. All such cosmological time crystals in the literature suffer from gradient instabilities occurring at Null Energy Condition violating phases where the square sound speed for cosmological perturbations becomes negative. Here we present stable cosmological time crystals. Our analysis suggests this new form of scalar matter--cosmic time crystals--may be considered as a physically viable cosmological matter source.

Is The Fiscal Theory of the Price Level Learnable?

Publisher: name: Carnegie Mellon University

Subjects: subject: 150399 Business and Management not elsewhere classified
subject: FOS: Economics and business

description: During the past several years, a striking body of literature has appeared in which it is argued that general price level determination is essentially a fiscal, rather than monetary, phenomenon. The most prominent papers have been those of Woodford (1994, 1995, 2001), Sims (1994, 1997), Leeper (1991), and Cochrane (1998, 2000), but there are several others of significance.1 If the theory expounded in these papers was valid in actuality, there would be major implications for the manner in which fiscal and monetary policies should be conducted, not only in individual economies but also within monetary unions.2 The purpose of the present paper is to describe this theory and provide one major reason why I believe that it is not relevant to actual economies, but instead is basically misleading. That position has been put forth in McCallum (2001a), but the present argument includes a new, different, and more satisfactory justification. In addition, the basic exposition is simplified here and several extensions are developed.

description: The variance reduction techniques are necessary for Monte Carlo calculations in which obtaining a detailed calculation result for a large and complex model is required. The GVR method named as global weight window generator (GWWG) was proposed by the FDS team. In this paper, two typical calculation examples, ISPRA-Fe benchmark in SINBAD (Shielding Integral Benchmark Archive Database) and TF Coils (Toroidal Field coils) of European HCPB DEMO (Helium Cooled Pebble Bed demonstration fusion plant), are used to study the performance of GWWG method. It can be seen from the calculation results that the GWWG method has a significant effect in accelerating the Monte Carlo calculation. Especially when the global convergence calculation results are needed, the acceleration effect (FOMG) can reach 10$^{5}$ or more. It proves that the GWWG method is an effective tool for deep-penetration simulations using Monte Carlo method.
Emergence of long wavelength pion oscillations following a rapid QCD phase transition

description: To model the dynamics of the chiral order parameter in a far from equilibrium QCD phase transition, we consider quenching in the O(4) linear sigma model. We summarize arguments and numerical evidence which show that in the period immediately following the quench arbitrarily long wavelength modes of the pion field are amplified. This results in large regions of coherent pion oscillations, and could lead to dramatic phenomenological consequences in ultra-relativistic heavy ion collisions. My talk was a description of work done with Frank Wilczek. In these proceedings, I sketch our central results, emphasizing several points that were raised in discussions at the conference.

description: Galaxies with polar rings consist of two subsystems, a disk and a ring, which rotate almost in orthogonal planes. In this paper, we analyze the parameters characterizing the composition of the interstellar medium and star formation in star-forming complexes, belonging to a polar ring galaxy NGC660. We show that star-forming regions in the ring of the galaxy are distinctively different from those in the galaxy disk. They possess substantially lower infrared luminosities, indicative of less dust mass in these regions than in a typical disk star-forming region. UV and H$α$ luminosities also appear to be lower in the ring, probably, being a consequence of its relatively recent formation.
