Phenomenology of single-inclusive jet production with jet radius and threshold resummation

Author(s): Liu, X; Moch, SO; Ringer, F | Abstract: © 2018 authors. We perform a detailed study of inclusive jet production cross sections at the LHC and compare the QCD theory predictions based on the recently developed formalism for threshold and jet radius joint resummation at next-to-leading logarithmic accuracy to inclusive jet data collected by the CMS Collaboration at S=7 and 13 TeV. We compute the cross sections at next-to-leading order in QCD with and without the joint resummation for different choices of jet radii R and observe that the joint resummation leads to crucial improvements in the description of the data. Comprehensive studies with different parton distribution functions demonstrate the necessity of considering the joint resummation in fits of those functions based on the LHC jet data.
Mobility Constraints and Labor Market Outcomes - Evidence from Credit Lotteries ∗

The views expressed in the paper are those of the authors and should not be cited to reﬂect the view of the Banco Central do Brasil. Abstract This paper assesses the role of vehicle ownership in reducing spatial mismatch between employers and employees. We exploit random time-series variation in the allocation of motorcycles through lotteries among participants in a ﬁnancial product in Brazil. We ﬁnd that individuals exhibit higher employment, earnings, and business ownership, and commute further after obtaining a motorcycle compared to participants who did not yet win a motorcycle. Early lottery winners still exhibit superior outcomes ﬁve years after all participants have been awarded a motorcycle. Consistent with a reduction in spatial mismatch, the eﬀects are strongest for individuals residing in areas with sparse public transportation and local labor markets. A lower incidence of job separations and a higher probability to be employed on a permanent contract after winning a motorcycle suggest that expanding the number and scope of potential employment opportunities through motorcycle ownership leads to more stable employer-employee matches.
ATOMIC DATA FOR S ii—TOWARD BETTER DIAGNOSTICS OF CHEMICAL EVOLUTION IN HIGH-REDSHIFT GALAXIES

Absorption-line spectroscopy is a powerful tool used to estimate element abundances in both the nearby and distant universe. The accuracy of the abundances thus derived is naturally limited by the accuracy of the atomic data assumed for the spectral lines. We have recently started a project to perform new extensive atomic data calculations used for optical/UV spectral lines in the plasma modeling code Cloudy using state of the art quantal calculations. Here, we demonstrate our approach by focussing on S ii, an ion used to estimate metallicities for Milky Way interstellar clouds as well as distant damped Lyman-alpha (DLA) and sub-DLA absorber galaxies detected in the spectra of quasars and gamma-ray bursts. We report new extensive calculations of a large number of energy levels of S ii, and the line strengths of the resulting radiative transitions. Our calculations are based on the configuration interaction approach within a numerical Hartree–Fock framework, and utilize both non-relativistic and quasirelativistic one-electron radial orbitals. The results of these new atomic calculations are then incorporated into Cloudy and applied to a lab plasma, and a typical DLA, for illustrative purposes. The new results imply relatively modest changes (≈0.04 dex) to the metallicities estimated from S ii in past studies. These results will be readily applicable to other studies of S ii in the Milky Way and other galaxies.
Spatial and temporal shifts in the diet of the barnacle Amphibalanus eburneus within a subtropical estuary

The success of many sessile invertebrates in marine benthic communities is linked to their ability to efficiently remove suspended organic matter from the surrounding water column. To investigate the diet of the barnacle Amphibalanus eburneus, a dominant suspension feeder within the Indian River Lagoon (IRL) of central Florida, we compared the stable isotopes ratios (δ13C and δ15N) of barnacle tissue to those of particulate organic matter (POM). Collections were carried out quarterly for a year from 29 permanent sites and at sites impacted by an Aureoumbra lagunensis bloom. δ13C and δ15N values of Amphibalanus eburneus varied across sites, but δ15N was more stable over time. There was a range of δ15N values of Amphibalanus eburneus tissue from 6.0‰ to 10.5‰ across sites. Because land-based sources such as sewage are generally enriched in 15N, this suggests a continuum of anthropogenic influence across sites in the IRL. Over 70% of the variation in δ15N values of Amphibalanus eburneus across sites was driven by the δ15N values of POM, supporting a generalist feeding strategy on available sources of suspended organic matter. The dominance of this generalist consumer in the IRL may be linked to its ability to consume spatially and temporally variable food resources derived from natural and anthropogenic sources, as well as Aureoumbra lagunensis cells. Generalist consumers such as Amphibalanus eburneus serve an important ecological role in this ecosystem and act as a sentinel species and recorder of local, site-specific isotopic baselines.
Fluctuations of the empirical measure of freezing Markov chains

In this work, we consider a finite-state inhomogeneous-time Markov chain whose probabilities of transition from one state to another tend to decrease over time. This can be seen as a cooling of the dynamics of an underlying Markov chain. We are interested in the long time behavior of the empirical measure of this freezing Markov chain. Some recent papers provide almost sure convergence and convergence in distribution in the case of the freezing speed n^{-θ} , with different limits depending on θ 1. Using stochastic approximation techniques, we generalize these results for any freezing speed, and we obtain a better characterization of the limit distribution as well as rates of convergence as well as functional convergence.
Making Repairs in Description Logics More Gentle (Extended Abstract)

The classical approach for repairing a Description Logic ontology O in the sense of removing an unwanted consequence α is to delete a minimal number of axioms from O such that the resulting ontology O (cid:48) does not have the consequence α . However, the complete deletion of axioms may be too rough, in the sense that it may also remove consequences that are actually wanted. To alleviate this problem, we propose a more gentle notion of repair in which axioms are not deleted, but only weakened. On the one hand, we investigate general properties of this gentle repair method. On the other hand, we pro-pose and analyze concrete approaches for weakening axioms expressed in the Description Logic EL .
CEREAL CYST NEMATODES : STATUS , RESEARCH AND OUTLOOK Proceedings of the First Workshop of the International Cereal Cyst Nematode Initiative , 21-23 October 2009 , Antalya , Turkey

The first meeting of the International Cereal Cyst Nematode Initiative, held in October 2009 in Turkey, involved over 60 scientists from wheat-growing regions in Asia, Australia, Europe, north Africa and North America. Cereal cyst nematodes (CCN) are damaging root parasites of barley, oat, wheat and related plants; the most important species being Heterodera avenae, H. filipjevi and H. latipons. Forty three papers in this volume cover: the history and status of CCN both globally and regionally; research on CCN morphological, genetic and ecology diversity; development and deployment of host resistance as the principal means of control, including advancements provided by molecular technology; and investigations into other types of control and opportunities for integrated management. The papers provide valuable insight into the impact of CCN and endeavours to provide sustainable management options for farmers. CCN’s impact ranges from severe in resourcelimited cropping systems with high pathotype diversity through to the now easily managed situation in Australia, with one pathotype and many resistant cultivars released. In many countries, unacceptable economic losses continue and international collaboration is needed to ensure that appropriate genetic resources and technology are developed, disseminated and applied where the need is greatest.

Structure function scaling in a Reλ = 250 turbulent mixing layer

A highly resolved Direct Numerical Simulation of a spatially developing turbulent mixing layer is presented. In the fully developed region, the flow achieves a turbulent Reynolds number Reλ = 250, high enough for a clear separation between large and dissipative scales, so for the presence of an inertial range. Structure functions have been calculated in the self-similar region using velocity time series and Taylor's frozen turbulence hypothesis. The Extended Self-Similarity (ESS) concept has been employed to evaluate relative scaling exponents. A wide range of scales with scaling exponents and intermittency levels equal to homogeneous isotropic turbulence has been identified. Moreover an additional scaling range exists for larger scales; it is characterized by smaller exponents, similar to the values reported in the literature for flows with strong shear.
What do eye movements in the visual world reflect? A case study from adjectives

A common dependent measure used in visual-world eyetracking experiments is the proportion of looks to a visually depicted object in a certain time window after the onset of the critical stimulus. When interpreting such data, a common assumption is that looks to the object reflect the listener’s belief that the object is the intended target referent. While this is intuitively plausible (at least for paradigms in which the task requires selecting a referent), relatively little is known about how exactly the proportion of looks to an object is related to a listener’s current belief about that object. Here, we test a simple, explicit linking hypothesis: the proportion of looks to an object correlates with the probability that the listener assigns to the object being the target. To test this hypothesis, we supplement the eye-tracking data from Leffel, Xiang, and Kennedy (2016) with an offline incremental decision task to measure participants’ beliefs about the intended referent at various points in the unfolding sentence, and assess the extent to which these beliefs predict the eye-tracking data. The results suggest that the degree to which an object is believed to be the referent is only one factor that affects eye movements in referential tasks. Preliminary free production data we have collected for the scenes suggests that utterance expectations also play a role. We discuss methodological implications of these results for experimental linguistics.
Fuzzy and Sample Entropies as Predictors of Patient Survival Using Short Ventricular Fibrillation Recordings during out of Hospital Cardiac Arrest

Optimal defibrillation timing guided by ventricular fibrillation (VF) waveform analysis would contribute to improved survival of out-of-hospital cardiac arrest (OHCA) patients by minimizing myocardial damage caused by futile defibrillation shocks and minimizing interruptions to cardiopulmonary resuscitation. Recently, fuzzy entropy (FuzzyEn) tailored to jointly measure VF amplitude and regularity has been shown to be an efficient defibrillation success predictor. In this study, 734 shocks from 296 OHCA patients (50 survivors) were analyzed, and the embedding dimension (m) and matching tolerance (r) for FuzzyEn and sample entropy (SampEn) were adjusted to predict defibrillation success and patient survival. Entropies were significantly larger in successful shocks and in survivors, and when compared to the available methods, FuzzyEn presented the best prediction results, marginally outperforming SampEn. The sensitivity and specificity of FuzzyEn were 83.3% and 76.7% when predicting defibrillation success, and 83.7% and 73.5% for patient survival. Sensitivities and specificities were two points above those of the best available methods, and the prediction accuracy was kept even for VF intervals as short as 2s. These results suggest that FuzzyEn and SampEn may be promising tools for optimizing the defibrillation time and predicting patient survival in OHCA patients presenting VF.
A Combination of Wheat Bran and Vegetable Oils as Feedstuff in Laying Hens’ Diet: Impact on Egg Quality Parameters

Wheat bran (WB) is an important side product of the milling industry and plays an increasing role in animal feeding. Despite its nutritional value, its application is limited as a result of its pronounced fiber content. Taking into account the potential use of WB supplementation in feed for laying hens thereby replacing human edible foodstuffs, the influence of different WB levels (0 g·kg-1, 75 g·kg-1, and 150 g·kg-1) combined with sunflower or rapeseed oil on egg quality was studied. Among the egg-related quality parameters investigated, eggshell cleanliness, shell rigidity, egg weight, haugh units, yolk and albumen mass, color, pH value, dry matter, crude protein, crude ash, fatty acid spectrum, cholesterol and α-tocopherol of the yolk were monitored. No negative effect of WB supplementation was observed in terms of egg weight, shell weight, albumen weight, yolk weight, haugh unit, shell thickness and eggshell breaking strength. However, certain parameters (i.e. α-tocopherol content, Σn-3 PUFA) were enhanced by feeding 75 g·kg-1 and 150 g·kg-1 WB. The use of WB (75 g·kg-1 and 150 g·kg-1) had no negative effect on egg quality and can, therefore, be recommended for laying hen diets up to 150 g·kg-1. Additionally, the application of rapeseed oil high in Σn-3 PUFA resulted in yolks exhibiting a low Σn-6 PUFA/Σn-3 PUFA ratio.
Branded Products as a Passport to Global Citizenship: Perspectives from Developed and Developing Countries

This article focuses on belief in brands as a passport to global citizenship, defined as a person's perception that global brands create an imagined global identity. The authors assess the effects of this belief on the importance consumers assign to branded products and also examine the antecedent effects of cultural openness and consumer ethnocentrism. Their work focuses on the global youth market in the developing countries of Romania, Ukraine, and Russia and the developed U.S. market. The findings contribute to a broadened understanding of branding in a global marketplace by examining the associations between beliefs about global brands and the importance consumers attach to branded products in their daily lives.
When LoRaWAN Frames Collide

LoRa, an abbreviation of Long Range, is a Low-Power Wide Area Network (LPWAN) radio technology that has quickly gained popularity as a communications means for the Internet-of-Things (IoT). LoRa is typically used together with the MAC protocol LoRaWAN and operates in the license-free ISM-bands. As such, anyone is allowed to deploy their own LoRaWAN network, provided that they adhere to the LoRaWAN specification and ISM regulations. However, an uncoordinated deployment of LoRaWAN networks may cause neighboring networks to interfere and LoRaWAN frames to collide. In this paper, we present an in-depth investigation of LoRaWAN frame collisions -- and the capture effect in particular -- through various experiments. Contrary to previous research, we focus on correct reception of data at the application, instead of at the gateway, and we consider multi-gateway, multi-provider, and dense scenarios to obtain insight into collisions within actual networks.
Present kinematics of the Tjörnes Fracture Zone, North Iceland, from campaign and continuous GPS measurements

campaign GPS (EGPS) data points, which have been regularly observed since 1997. We extract the steady-state interseismic velocities within the TFZ by correcting the GPS data for volcanic inﬂation of Theistareykir— the westernmost volcano of the NVZ—using a model with a magma volume increase of 25 × 10 6 m 3 , constrained by InSAR time-series analysis results. The improved velocity ﬁeld based on 58 GPS stations conﬁrms the robustness of our previous model and allows to better constrain the free model parameters. For the HFF we ﬁnd a slightly shallower locking depth of ∼ 6.2 km and a slightly higher slip-rate of ∼ 6.8 mm yr − 1 that again result in the same seismic potential equivalent to a M w 6.8 earthquake. The much larger number of GPS velocities improves the statistically estimated model parameter uncertainties by a factor of two, when compared to our previous study, a result that we validate using Bayesian estimation.
Fracture strength of glass chips for high-pressure microfluidics

High-pressure microfluidics exposes new areas in chemistry. In this paper, the reliability of transparent borosilicate glass chips is investigated. Two designs of circular cavities are used for fracture strength tests, either 1.6 mm wide with rounded corners to the fluid inlets, or 2.0 mm wide with sharp inlet corners. Two kinds of tests are done, either short-term, e.g. pressurization to fracture at room temperature, or long-term, with fracture at constant pressurization for up to one week, in the temperature region 11–125 °C. The speed of crack fronts is measured using a high-speed camera. Results show fracture stresses in the range of 129 and 254 MPa for short-term measurements. Long-term measurements conclude the presences of a temperature and stress dependent delayed fracture. For a reliability of one week at 11–38 °C, a pressure limit is found at the lower end of the short-term measurements, or 15% lower than the average. At 80 °C, this pressure limit is 45% lower. Crack speeds are measured to be 10−5 m s−1 during short-term fracture. These measurements are comparable with estimations based on slow crack growth and show that the growth affects the reliability of glass chips. This effect is strongly affected by high temperatures, thus lowers the operating window of high-pressure glass microfluidic devices.
The group-sphere model of international news flow: A cross-national comparison of news sites

Why are some countries mentioned very frequently in international news while others are not? Seeking to improve previous explanations in the literature, this study employs a large corpus of news sites in 11 countries and 10 languages over a 3-year period. A systematic computer-driven analysis revealed a similar pattern common to international news in all countries. The best explanation for the prominence of a foreign country in the news included variables from three groups (national traits, relatedness, and events), each representing different spheres (economic, social, and political), respectively. The conceptual contribution and empirical implications for future studies are discussed.
Foreshadow: Extracting the Keys to the Intel SGX Kingdom with Transient Out-of-Order Execution

Trusted execution environments, and particularly the Software Guard eXtensions (SGX) included in recent Intel x86 processors, gained significant traction in recent years. A long track of research papers, and increasingly also real-world industry applications, take advantage of the strong hardware-enforced confidentiality and integrity guarantees provided by Intel SGX. Ultimately, enclaved execution holds the compelling potential of securely offloading sensitive computations to untrusted remote platforms. We present Foreshadow, a practical software-only microarchitectural attack that decisively dismantles the security objectives of current SGX implementations. Crucially, unlike previous SGX attacks, we do not make any assumptions on the victim enclave's code and do not necessarily require kernel-level access. At its core, Foreshadow abuses a speculative execution bug in modern Intel processors, on top of which we develop a novel exploitation methodology to reliably leak plaintext enclave secrets from the CPU cache. We demonstrate our attacks by extracting full cryptographic keys from Intel's vetted architectural enclaves, and validate their correctness by launching rogue production enclaves and forging arbitrary local and remote attestation responses. The extracted remote attestation keys affect millions of devices.
Receptiveness of the stigma and in vitro germination of orange pollen, submitted to different temperatures

The study was carried out in order to evaluate the effect of temperature and in vitor stigma receptivity on regeneration of orange cultivar (Valencia, Pera and Natal) pollen. Two experiments were carried out, in the first the ideal temperature of germination was assessed. Pollen was obtained from flowers at the balloon stage and inoculated in culture medium with 10 g L-1 agar, 200 mg L-1 boric acid, 100 g L-1 sucrose, 800 mg L-1 calcium nitrate, pH adjusted to 6,5 and incubated in a BOD chamber at temperatures of 23, 24, 25, 26 and 27oC during a 24-hour photoperiod. After 12 hours of incubation, the best temperature for pollen grain germination was 25oC for all varieties. In a second experiment, in order to test the receptivity of the stigma, flowers were collected at different flowering stages: small bud, balloon and open flower. The stigmas were by immersion exposed to hydrogen peroxide (perioxidase reaction), 3% for 3 minutes. Through the technique of Zeisler (1938), better results were detected at the balloon stage with 80 to 100% receptivity, while for the open flower the receptivity presented maximum indexes.
Echinacea purpurea. Aerial Parts Contain Multiple Antiviral Compounds

Abstract Stems, leaves, and flowers of Echinacea purpurea. (L.) Moench (Heliantheae: Asteraceae) were fractionated by various solvents and the fractions evaluated for antiviral activity in relation to chemical composition and distribution within the plant. All of the aqueous fractions contained potent activity against herpes simplex virus and influenza virus. However, although some of this activity could be attributed to polysaccharide and cichoric acid components, their individual contributions could not account for the total antiviral activity; other potent antivirals must be present. In addition, the ethanol- and ethyl acetate–soluble fractions from leaves and stem contained an uncharacterized but potent antiviral photosensitizer, which was absent from the flower extract. None of the fractions, however, contained anti-rhinovirus activity. Thus, part of the alleged benefits of Echinacea purpurea. extracts can be attributed to the presence of anti-influenza and anti-HSV compounds, and some of these activities are likely to be present in various commercial tinctures, teas, capsules, and tablets.
