The object of this study is to investigate the effect of ethanol–gasoline blends on CO and HC cold start emissions from a fourstroke motorcycle. Nowadays, due to catalyst improvements and efficient electronic mixture control, a significant part of the total emissions during a trip takes place during the cold phase. The employ of alternative fuels could be one of means to lessen the cold-start emissions from two-wheeler engines: ethanol is known as potential alcohol alternative fuel for spark ignition engines, which can be blended with gasoline to increase oxygen content and then to decrease CO and HC emissions. From this considerations, an experimental-analytical investigation was performed on the exhaust cold extra emissions of one motorcycle belonging to the Euro-3 legislative category. The study explains a calculation procedure to model the cold start transient behavior of motorcycles in order to evaluate the impact of ethanol addition (10, 20 and 30 vol.%) on cold start emissions compared with a reference commercial gasoline. Results of the tests indicate that CO and HC cold start extra emissions by using ethanol–gasoline blended fuels decrease compared to the use of unleaded gasoline. Emission factors during the cold start transient were quantized as a function of the ethanol percentage in the blended fuels. © 2013 The Authors. Published by Elsevier Ltd.

A URANS solver has been applied to the analysis of unsteady effects induced by incoming wakes in high-lift, low-Reynoldsnumber cascade flows. The study has been carried out using a novel, transition-sensitive, turbulence model. It is based on the coupling of additional transport equations, one for the so-called laminar kinetic energy (LKE) and one for a turbulence indicator function, with an algebraic Reynolds stress formulation based on the k−ωmodel. The transition modelling strategy and its coupling with the turbulence equations is conceived as an extension of the laminar kinetic energy concept for unsteady flow calculations. Three high-lift bladings (T106A, T106C, and T2), recently tested in the framework of two European research projects were considered for the present study. The cascades are characterized by separated flow transition in steady conditions. A detailed comparison between measurements and computations, in terms of blade loading distributions and cascade lapse rates will be presented and discussed. Some specific features of wake-induced transition will also be discussed. Results obtained with the proposed model show its ability to predict the major effects of passing wakes on the boundary layer development and loss characteristics of high-lift cascades operating in LP-turbine conditions. c © 2013 The Authors.

Approximating Polygons and Subdivisions with Minimum Link Paths

We study several variations on one basic approach to the task of simplifying a plane polygon or subdivision: Fatten the given object and construct an approximation inside the fattened region. We investigate fattening by convolving the segments or vertices with disks and attempt to approximate objects with the minimum number of line segments, or with near the minimum, by using efficient greedy algorithms. We give some variants that have linear or O(n log n) algorithms approximating polygonal chains of n segments. We also show that approximating subdivisions and approximating with chains with. no self-intersections are NP-hard.

A very efficient implementation of a lattice Boltzmann (LB) kernel in 3D on a graphical processing unit using the compute unified device architecture interface developed by nVIDIA is presented. By exploiting the explicit parallelism offered by the graphics hardware, we obtain an efficiency gain of up to two orders of magnitude with respect to the computational performance of a PC. A non-trivial example shows the performance of the LB implementation, which is based on a D3Q13 model that is described in detail. 1. Introduction A graphical processing unit (GPU) is specifically designed to be extremely fast at processing large graphics data sets (e.g. polygons and pixels) for rendering tasks. The use of the GPU to accelerate non-graphics computations has drawn much attention (Bolz et al. 2003, Krüger and Westermann 2003, Buck et al. 2004). This is due to the fact that the computational power of GPUs has exceeded that of PC-based CPUs by more than one order of magnitude, while being available for a comparable price. For example, the recently released nVIDIA GeForce 8800 Ultra has been observed to deliver over 4 £ 10 11 single precision (32-bit) floating operations per second (400 GFLOPS) (NVIDIA 2008). In comparison, the theoretical peak performance of the Intel Core 2 Duo 3 GHz is only 24 GFLOPS for double precision and 48 GFLOPS for single precision. Also, the bandwidth to the memory interface is much larger: memory bandwidth for desktop computers ranges from 5.3 to 10.7 GB/s, whereas the nVIDIA GeForce 8800 Ultra delivers up to 104 GB/s. Due to the facts that lattice Boltzmann methods (LBM) operate on a finite difference grid, are explicit in nature and usually require only next neighbour interaction, they are very suitable for …
Magma genesis and mantle sources at the Mid-Atlantic Ridge East of Ascension Island

Results from the Meteor 41-2 cruise to the Mid-Atlantic Ridge (MAR) between 6° and 11°S, are reported. Six spreading segments, which are bounded by non-transform offsets were discovered and numbered from north to south. Anomalously shallow segments (Segment 4 and 5) occur between ~9°S and 11°S, pointing to an excess volcanism in this area. For detailed geochemical and petrological investigations samples (mostly glasses) were taken every 5-10 km. The cause of the melting anomaly beneath Segments 4 & 5 could be either a hot mantle plume or a cold mantle heterogeneity. A mantle plume with a low excess temperature of about 50° C (Minshull et al., 1998) is unlikely, instead melting of a H2O enriched, fertile mantle is proposed. Higher H2O and incompatible element concentrations are known to lower the mantle solidus significantly. HREE depletion mainly in Segment 5 lavas suggest initial melting in the garnet peridotite stability field.
Validation of Aerosol Optical Depth from Terra and Aqua MODIS Retrievals over a Tropical Coastal Site in China

Abstract This study compares the aerosol optical depth (AOD) Level 2 Collection 5 products from the Terra and Aqua Moderate Resolution Imaging Spectroradiometers (MODIS) with ground-based measurements from a Microtops II sun photometer over Sanya (18.23°N, 109.52°E), a tropical coastal site in China, from July 2005 to June 2006. The results indicate that the Terra and Aqua MODIS AOD retrievals at 550 nm have good correlations with the measurements from the Microtops II sun photometer. The correlation coefficients for the linear regression fits (R2) are 0.83 for Terra and 0.78 for Aqua, and the regressed intercepts are near zero (0.005 for Terra, 0.009 for Aqua). However, the Terra and Aqua MODIS are found to consistently underestimate AOD with respect to the Microtops II sun photometer, with slope values of 0.805 (Terra) and 0.767 (Aqua). The comparison of the monthly mean AOD indicates that for each month, the Terra and Aqua MODIS retrievals are matched with corresponding Microtops measurements but are systematically less than those of the Microtops. This validation study indicates that the Terra and Aqua MODIS AOD retrievals can adequately characterize the AOD distributions over the tropical coastal region of China, but further efforts to eliminate systematic errors are needed.
Board of Regents of the University of Wisconsin System Evaluation of the Subjective Probabilities of Survival in the Health and Retirement Study

In the Health and Retirement Study respondents were asked about the chances they would live to 75 or to 85. We analyze these responses to determine if they behave like probabilities of survival, if their averages are close to average probabilities in the population, and if they have correlations with other variables that are similar to correlations with actual mortality outcomes. We find that generally they do behave like probabilities and that they do aggregate to population probabilities. Most remarkable, however, is that they covary with other variables in the same way actual outcomes vary with the variables. For example, respondents with higher socioeconomic status give higher probabilities of survival, whereas respondents who smoke give lower probabilities. We conclude that these measures of subjective probabilities have great potential use in models of intertemporal decision-making under uncertainty.

ATLAS Measurements of CP Violation and Rare Decays in Beauty Mesons

The ATLAS experiment at the Large Hadron Collider (LHC) has performed accurate measurements of mixing and CP violation in the neutral B mesons, and also of rare processes happening in electroweak FCNC-suppressed neutral B-mesons decays. This contribution focuses on the latest results from ATLAS, including measurements of rare processes $B^0_s \to \mu^+\mu^-$ and $B^0 \to \mu^+\mu^-$, and measurements of CP violation in $B^0_s \to J/\psi\phi$.
Memoirs on Differential Equations and Mathematical Physics

The purpose of this paper is to construct explicitly, in terms of elementary functions, fundamental matrices of solutions to the differential equations of the elasticity theory of hemitropic materials with regard to thermal stresses. We consider the differential equations corresponding to the static equilibrium case, and also to the pseudo-oscillations and steady state oscillations cases. We derive the corresponding Green’s formulas and construct the integral representation formulas of solutions by means of generalized layer and Newtonian potentials. We formulate the basic boundary value problems in appropriate function spaces and prove the uniqueness theorems. We develop the potential method and prove the existence and regularity theorems for basic and mixed type boundary value problems. 2000 Mathematics Subject Classification. 35J55, 74A60, 74G05, 74G30, 74F05.
Mathematical and numerical analysis of a nonlocal Drude model in nanoplasmonics

In this paper, we consider the frequency-domain Maxwell's equations coupled to a nonlocal Drude model which describes the nonlocal optical response in metallic nanostructures. We prove the existence and uniqueness of weak solutions to the coupled equations. A Galerkin finite element method based on the Raviart--Thomas and Nedelec elements is proposed to solve the equations and the associated error estimates are given. This is the first work on the mathematical and numerical analysis of this model. Numerical examples are presented to verify our theoretical analysis.
Nearly Finitary Matroids

In this thesis, we study nearly finitary matroids by introducing new definitions and prove various properties of nearly finitary matroids. In 2010, an axiom system for infinite matroids was proposed by Bruhn et al. We use this axiom system for this thesis. In Chapter 2, we summarize our main results after reviewing historical background and motivation. In Chapter 3, we define a notion of spectrum for matroids. Moreover, we show that the spectrum of a nearly finitary matroid can be larger than any fixed finite size. We also give an example of a matroid with infinitely large spectrum that is not nearly finitary. Assuming the existence of a single matroid that is nearly finitary but not $k$-nearly finitary, we construct classes of matroids that are nearly finitary but not $k$-nearly finitary. We also show that finite rank matroids are unionable. In Chapter 4, we will introduce a notion of near finitarization. We also give an example of a nearly finitary independence system that is not $k$-nearly finitary. This independence system is not a matroid. In Chapter 5, we will talk about Psi-matroids and introduce a possible generalization. Moreover, we study these new matroids to search for an example of a nearly finitary matroid that is not $k$-nearly finitary. We have not yet found such an example. In Chapter 6, we will discuss thin sums matroids and consider our problem restricted to this class of matroids. Our results are motivated by the open problem concerning whether every nearly finitary matroid is $k$-nearly finitary for some $k$.
Hepatoprotective and antioxidant effects of Ocimum basilicum extract in CCL4-induced hepatotoxic rats compared with Silymarin

The aim of this study was to evaluate pulmonary function test, acute phase proteins, pro-inflammatory cytokines, electrolyte balance and electrocardiographic alterations in BRD affected calves compared to pen matched healthy control calves. A total of 30 calves (20 BRD affected calves and 10 apparently healthy calves) were used in this study. The BRD affected calves showed significant (P<0.05) reduction in blood pH, partial pressure of oxygen, oxygen saturation, calcium, phosphorus, magnesium, sodium and chloride, and significant (P<0.05) increase in partial pressure of carbon dioxide, total carbon dioxide and potassium. Acute phase proteins and Proinflammatory cytokines assessment revealed a significant (P<0.05) increase of serum amyloid A, haptoglobin, fibrinogen and interleukin-6 in diseased calves compared to healthy control calves. Electrocardiographic examination of BRD affected calves revealed a significant increase in heart rate with a significant (P<0.05) alteration in ECG wave trace parameters (P wave, QRS complex, T wave, PR interval, QT interval). In conclusion, measurement of pulmonary function test, APPs, cytokines and ECG could be used as valuable and early diagnostic tools for BRD diagnosis in feedlot cattle calves.
Emerging Applications of Liquid Biopsies in Ovarian Cancer

Liquid biopsy is a new diagnostic tool in precision oncology that can be used as a complementary or alternative method to surgical biopsies. It is a cutting-edge sampling technique that examines distinct cancer components, such as exosomes and circulating tumor cells discharged into the peripheral circulation, to identify tumor biomarkers through various methods, including polymerase chain reaction (PCR). Liquid biopsy has several benefits, including its non-invasiveness and practicality, which permit serial sampling and long-term monitoring of dynamic tumor changes. Ovarian cancer (OC), the most lethal gynecologic malignancy in the world, is typically diagnosed at stages II and III, which makes recovery and treatment extremely difficult. Relapsed OC and chemotherapy resistance of ovarian tumor cells are other clinical challenges. Although liquid biopsy is not a routinely used diagnostic test, it should be utilized in the diagnosis and prognosis of OC for early detection and treatment. It is less intrusive than conventional tissue biopsies, allowing for the continuous collection of serial blood samples to track cancer development in real time. Before therapeutic application, more investigation is required to pinpoint the particular release processes, the source tissue, and the biological significance of the bulk of liquid biopsy contents.
Effects of Simulated NH4 + Deposition on CO2 Fluxes in the Hulun Buir Meadow Steppe of Inner Mongolia, China

Abstract: Atmospheric nitrogen (N) deposition may affect carbon (C) sequestration in terrestrial ecosystem. The main objective of this paper was to test the hypothesis that N addition would increase CO2 emission in the N limited meadow steppe in Inner Mongolia, China. Response of CO2 fluxes to simulated N deposition was studied in the growing season of 2008 and 2009 by static chamber and gas chromatograph techniques. Parallel to the flux measurements, soil temperature, soil moisture, TOC, DOC, soil NH4 + and NO3 - were measured at the same time. The results indicated that two-year N additions had no significant effect on NH4 +, but slightly increased NO3 - in the later period. The HN treatment tended to increase CO2 fluxes in the two years, and LN treatment tended to decrease CO2 fluxes in 2008, and shifted to increase CO2 fluxes in later growing season of 2009. N addition significantly increased the aboveground biomass and root biomass. The correlation between CO2 fluxes and moisture or temperature factors did not significantly change due to N addition, but N addition enhanced the moisture sensitivity of CO2 fluxes as well as the temperature sensitivity of CO2 fluxes. These results suggest that the increasing ammonium N deposition would be likely to stimulate CO2 fluxes in the meadow steppe of Inner Mongolia, China.

Abstract This paper provides a framework and estimates of enrollment rates per natural and combines them with previous income and child mortality per-natural estimates to produce a Human Development Index by country of birth as opposed to country of residence (per natural). The methodology is applied for 1990 and 2000 to provide estimates of growth rates of this measure over the period. The paper also develops and illustrates a framework for estimating an education place premium, and discusses how it is related to per natural measures. The peoples of the least developed countries stand to gain the most from international migration, but there are potentially significant gains to migration between developing countries as well.
FeGenie: a comprehensive tool for the identification of iron genes and iron gene neighborhoods in genomes and metagenome assemblies

Iron is a micronutrient for nearly all life on Earth. It can be used as an electron donor and electron acceptor by iron-oxidizing and iron-reducing microorganisms, and is used in a variety of biological processes, including photosynthesis and respiration. While it is the fourth most abundant metal in the Earth’s crust, iron is often limiting for growth in oxic environments because it is readily oxidized and precipitated. Much of our understanding of how microorganisms compete for and utilize iron is based on laboratory experiments. However, the advent of next-generation sequencing and the associated surge in publicly-available sequence data has now made it possible to probe the structure and function of microbial communities in the environment. To bridge the gap between our understanding of iron acquisition and utilization in model microorganisms and the plethora of sequence data available from environmental studies, we have created a comprehensive database of hidden Markov models (HMMs) that is based on genes related to iron acquisition, storage, and reduction/oxidation. Along with this database, we present FeGenie, a bioinformatics tool that accepts genome and metagenome assemblies as input and uses our comprehensive HMM database to annotate the provided datasets with respect to iron-related genes and gene clusters. An important contribution of this tool is the efficient identification of genes involved in iron oxidation and dissimilatory iron reduction, which have been largely overlooked by standard annotation pipelines. While this tool will not replace the reliability of culture-dependent analyses of microbial physiology, it provides reliable predictions derived from the most up-to-date genetic markers. FeGenie’s database will be maintained and continually-updated as new genetic markers are discovered. FeGenie is freely available: https://github.com/Arkadiy-Garber/FeGenie.
