The challenges of mining logging data in ATLAS
Authors: Gallas Elizabeth J , Ozturk Nurcan 
Published: September 2019

Processing ATLAS event data requires a wide variety of auxiliary information from geometry, trigger, and conditions database systems. This information is used to dictate the course of processing and refine the measurement of particle trajectories and energies to construct a complete and accurate picture of the remnants of particle collisions. Such processing occurs on a worldwide computing grid, necessitating wide-area access to this information.
Event processing tasks may deploy thousands of jobs. Each job calls for a unique set of information from the databases via SQL queries to dedicated squids in the ATLAS Frontier system, a system designed to pass queries to the database only if that result has not already been cached from another request. Many queries passing through Frontier are logged in an Elastic Search cluster along with pointers to the associated tasks and jobs, various metrics, and states at the time of execution. PanDA, which deploys the jobs, stores various configuration files as well as many log files after each job completes. Information is stored at each stage, but no system contains all information needed to draw a complete picture. This presentation describes the challenges of mining information from these sources to compile a view of database usage by jobs and tasks as well as assemble a global picture of the coherence and competition of tasks in resource usage to identify inefficiencies and bottlenecks within the overall system.
A new approach for ATLAS Athena job configuration
Authors: Lampl Walter 
Published: September 2019

The offline software framework of the ATLAS experiment (Athena) consists of many small components of various types like Algorithm, Tool or Service. To assemble these components into an executable application for event processing, a dedicated configuration step is necessary. The configuration of a particular job depends on the work-flow (simulation, reconstruction, high-level trigger, overlay, calibration, analysis ...) and the input data (real or simulated data, beam-energy, ...).
The configuration step is done by executing python code. The resulting config-uration depends on optionally pre-set flags as well as meta-data about the data to be processed. For the python configuration code, there is almost no structure enforced, leaving the full power of python to the user.
While this approach did work, it also proved to be error prone and complicated to use. It also leads to jobs containing more components that they actually need. For LHC Run 3 a more robust system is envisioned. It is still based on python but enforces a structure and emphasis modularity. This contribution briefly reports about the configuration system used during LHC Run 1 and Run 2 and details the prototype of an improved system to be used in Run 3 and beyond.

Building, testing and deploying of coherent large software stacks is very challenging, in particular when they consist of the diverse set of packages required by the LHC experiments, the CERN Beams Department and data analysis services such as SWAN. These software stacks include several packages (Grid middleware, Monte Carlo generators, Machine Learning tools, Python modules) all available for a large number of compilers, operating systems and hardware architectures.
To address this challenge, we developed an infrastructure around a tool called lcgcmake. Dedicated modules are responsible for building the packages, con-trolling the dependencies in a reliable and scalable way. The distribution relies on a robust and automatic system, responsible for building and testing the packages, installing them on CernVM-FS and packaging the binaries in RPMs and tarballs. This system is orchestrated through Jenkins on build machines provided by the CERN Openstack facility. The results are published through user-friendly web pages.
In this paper we will present an overview of these infrastructure tools and policies. We also discuss the role of this effort within the HEP Software Foundation (HSF). Finally we will discuss the evolution of the infrastructure towards container (Docker) technologies and the future directions and challenges of the project.
A modular software framework for test-beam data analysis. The TbGaudi package
Authors: Rachwał Bartłomiej , Szumlak Tomasz 
Published: September 2019

For purposes of test beam off-line data analysis a modular software framework has been developed and described in theses proceedings. The TbGaudi package allows to handle the test beam data for a set of runs, as well as the set of different devices under test in one-go, and finally obtain an integrated workflow to present the results.
All code is written in C++ programming language. A class based design makes it flexible to add any new features of the device under investigation following a plug-in scheme. Currently, the toolkit handles different types of analysis such as charge collection efficiency, track resolution and eta correction, implemented for non-uniform irradiated sensors.
The framework is applied for the LHCb upgrade studies for the VELO and UT groups.
Decay Chain Reconstruction at Belle II
Authors: Tenchini Francesco , Krohn Jo-Frederik 
Published: September 2019

The Belle II detector underwent commissioning in 2018. Featuring a state of the art vertex detector with innovative pixel sensors, it will record collisions of e+e-beams from the SuperKEKB accelerator which is slated to provide luminosities 40 times higher than KEKB.This will bring new opportunities and challenges for physicists seeking to perform precision measurements, as increasingly precise vertex position reconstruction and background rejection power is needed to take advantage of the unprecedented statistics provided.We discuss the vertex reconstruction techniques available that make such measurements possible and present an approach to particle decay reconstruction based on the global fit of the full decay chain, implemented using a Kalman Filter. This technique is especially well suited to the treatment of processes with neutral decays. It allows for improved background rejection, access to a larger number of decay modes and a flexible framework for consistent treatment of measurement uncertainties.
The obsolescence of Information and Information Systems CERN Digital Memory project
Authors: Le Meur Jean-Yves , Tarocco Nicola 
Published: September 2019

In 2016 was started the CERN Digital Memory project with the main goal of preventing loss of historical content produced by the organisation. The first step of the project was targeted to address the risk of deterioration of the most vulnerable materials, mostly the multimedia assets created in analogue formats from 1954 to the late 1990’s, like still and moving images kept on magnetic carriers. In parallel was studied today’s best practices to guarantee a long life to digital content, either born digital or resulting from a digitization process. If traditional archives and libraries have grown up during centuries establishing recognized standards to deal with the preservation of printed content, the field of digital archiving is in its infancy.
This paper shortly exposes the challenges when migrating hundreds of thousands of audio, slides, negatives, videotapes or films from the analogue to the digital era. It will then describe how a Digital Memory platform is being built, conform to the principles of the ISO-16363 digital object management norm that defines trustworthy digital repositories. Finally, as all information repository managers are faced with the necessary migration of underlying systems and the obsolescence of the information itself, the talk will explain how a digital archiving platform focusing only on content preservation could be of direct interest for most of the live systems.

Zusammenfassung
Hintergrund und Ziel der Studie Das Brandenburger Netzwerk Gesunde Kinder (NGK) ist ein durch geschulte Ehrenamtliche getragenes landesweites Gesundheitsförderprogramm für Familien mit Kindern von 0 bis 3 Jahren. Ziel der Studie ist auf der Basis der Schuleingangsuntersuchung (SEU) zu untersuchen, ob das NGK sich positiv auf die Gesundheit der Kinder auswirkt.
Methode In einer retrospektiven epidemiologischen Analyse der SEU, Schuljahr 2016/2017 (Netzwerkkinder/NK: 1152, Nicht-Netzwerkkinder/N-NK: 20 954) wird deskriptiv statistisch untersucht, ob es soziodemografische und gesundheitliche Unterschiede zwischen den Subgruppen NK und N-NK gibt. In einer logistischen Regressionsanalyse wird die Stärke des Einflusses des NGK bezogen auf gesundheitliche Zielgrößen und bei Adjustierung (wie soziale Lage und Region) berechnet.
Ergebnisse Eltern mit niedrigem und mittlerem Sozialstatus sowie Alleinerziehende nahmen häufiger im NGK (p<0,001) teil. NK verglichen zu N-NK brachten das U-Heft (94,3 / 91,5%, p<0,001) und den Impfausweis (95,7 / 91,7%, p<0,001) häufiger zur SEU mit. Eine höhere Quote der 1. Tetanus-, Diphtherie-, Pertussis-Auffrischimpfung wurde nach Netzwerkbegleitung festgestellt. Im adjustierten Modell zeigten NK geringere Quoten bei unvollständiger U2–U6 (OR 0,347 [95%-Konfidenzintervall: 0,192–0,627, p<0,001]), Impflücken (OR 0,621 [95%-KI: 0,508–0,758, p<0,000]) und höhere bei „optimal versorgt“ (OR 1,355 [95%-KI: 1,175–1,562, p<0,001]).
Schlussfolgerung Gesundheitlich profitierten die im Netzwerk begleiteten Kinder.

Published: September 2019

AbstractIntravascular papillary endothelial hyperplasia or Masson's tumor is a rare reactive disease of vascular origin characterized by exuberant proliferation of endothelial cells. Its importance lies in its ability to mimic a variety of diseases, both benign and malignant. Here, we present a unique case of Masson's tumor arising from the abdominal supraceliac aorta in a 32-year-old man initially misdiagnosed as leaking aortic pseudoaneurysm.

Objectives Malperfusion syndrome in the setting of acute Type A dissection (ATAD) is typically associated with poor prognosis. We evaluated the contemporary outcomes of patients with ATAD presenting with and without malperfusion syndrome who underwent aortic surgery.
Methods We performed a single-center, retrospective review of 103 consecutive patients that underwent surgery for ATAD. The cohort was dichotomized by patients with and without malperfusion syndromes. Multivariate and bivariate analyses were performed to evaluate association between the presence of malperfusion syndrome and operative outcomes.
Results A total of 29 (28.1%) patients presented with malperfusion syndrome. The 30-day mortality for patients presenting with and without malperfusion was 13.7 and 9.4%, respectively (p = 0.49). Patients with malperfusion syndrome had a shorter mean admission-to-incision interval of 4.3 ± 2.5 hours compared with 6.3 ± 4.6 hours for those without malperfusion (p = 0.02). Difference in 30-day mortality for patients with and without malperfusion syndrome was found to be nonsignificant on multivariate regression analysis (odds ratio: 1.53; 95% confidence interval: 0.40–5.82, p = 0.49).
Conclusions This series demonstrated that there was nonsignificant difference in early- or midterm outcomes for patients with and without malperfusion syndrome. Patients with malperfusion were taken to the operating room more rapidly than those without, which offers a potential explanation for the comparable outcome of the malperfusion cohort.

Published: September 2019

AbstractFluoroquinolones (FQs) are one of the most commonly prescribed classes of antibiotics. Their high tissue distribution and broad-spectrum antibacterial coverage make their use very attractive in numerous infectious diseases. Although generally well tolerated, FQs have been associated with different adverse effects including dysglycemia and arrhythmias. FQs have been also associated with a series of adverse effects related to collagen degradation, such as Achilles tendon rupture and retinal detachment. Recently, an association between consumption of FQs and increased risk of aortic aneurysm and dissection has been proposed. This article reviews the pathogenesis of thoracic aortic diseases, the molecular mechanism of FQ-associated collagen toxicity, and the possible contribution of FQs to aortic diseases.
A Randomized Crossover Comparison of Airway Sealing with the Laryngeal Mask Airway Ambu AuraFlex at Three Intracuff Pressures in Pediatric Laparoscopic Surgery
Authors: Liu Xiang , Tan Xiaona , Zhang Qi , Qiao Li , Shi Lei 
Published: September 2019

Abstract
Objective An adequate intracuff pressure is important to ensure sufficient sealing function when using supraglottic airway devices to protect the airway from secretions and achieve adequate positive pressure ventilation. The aim of this study is to analyze a feasible and effective alternative Ambu AuraFlex intracuff pressure in child's laparoscopic surgery.
Study Design Seventy-two children were included in this study. After insertion of the laryngeal mask airway AuraFlex, oropharyngeal leak pressure (OLP) was measured at intracuff pressures of 10, 30, and 60-cmH2O according to one of six sequences produced on the basis of 3 × 6 Williams crossover design. During the intraoperative period, AuraFlex was maintained using the last intracuff pressure of the allocated sequence. Oropharyngeal leak pressure, peak airway pressure, the fiberoptic view, mucosal change, and complications were assessed at three intracuff pressures.
Results The OLP at the intracuff pressure of 10 cmH2O was significantly lower than that of 30 cmH2O (2# 18.1 ± 1.5 vs. 19.5 ± 1.4 cmH2O, p = 0.001; 2.5# 17.7 ± 1.2 vs. 20.2 ± 1.4, p = 0.001) and 60 cmH2O (2# 18.1 ± 1.5 vs. 20.0 ± 1.3 cmH2O, p = 0.002; 2.5# 17.7 ± 1.2 vs. 20.8 ± 1.1, p = 0.003). Compared with the peak airway pressure in pre-and postpneumoperitoneum, the OLP was significantly higher. Subgroup analysis showed no differences in mucosal change and complications.
Conclusion Intracuff pressures of 30 may be sufficient for the Ambu AuraFlex in child's laparoscopic surgery, and there may be no added benefit of an intracuff pressure of 60 cmH2O, as oropharyngeal leak pressures were similar.
Spatiotemporal patterns of US drought awareness
Authors: Kim Sungyoon , Shao Wanyun , Kam Jonghun 
Published: September 2019

AbstractDrought is a creeping climatological phenomenon with persistent precipitation deficits. Unlike rapid onset natural hazards such as floods and wildfires, the intangible and gradual characteristics of drought cause a lack of social response during the onset. The level of awareness of a local drought increases rapidly through mass media reports and online information searching activities when the drought reaches its peak severity. This high level of local drought awareness drives concerns for water shortage and support for water policy. However, spatiotemporal patterns of national-scale drought awareness have never been studied due to constraints imposed by time-consuming and costly survey data collection and surveys’ limited sample sizes. Here, we present the national-scale study to reveal the spatiotemporal patterns of drought awareness over the contiguous United States (CONUS) using Google Trends data and Principal Component Analysis (PCA). Results show that the first two PC modes can explain 48% (38% for PC1 and 10% for PC2) of the total variance of state-level drought awareness. We find that the PC1 mode relates to a national pattern of drought awareness across the CONUS. The spatiotemporal patterns further imply that residents in the Northeastern US region are the most aware of the emergence of drought, regardless of the geographic location of the occurrence. The results illustrate how big data, such as search query and social media data, can help develop an effective and efficient plan for drought mitigation in the future.

AbstractThe quantity and complexity of scientific and technological information provided to policymakers have been on the rise for decades. Yet little is known about how to provide science advice to legislatures, even though scientific information is widely acknowledged as valuable for decision-making in many policy domains. We asked academics, science advisers, and policymakers from both developed and developing nations to identify, review and refine, and then rank the most pressing research questions on legislative science advice (LSA). Experts generally agree that the state of evidence is poor, especially regarding developing and lower-middle income countries. Many fundamental questions about science advice processes remain unanswered and are of great interest: whether legislative use of scientific evidence improves the implementation and outcome of social programs and policies; under what conditions legislators and staff seek out scientific information or use what is presented to them; and how different communication channels affect informational trust and use. Environment and health are the highest priority policy domains for the field. The context-specific nature of many of the submitted questions—whether to policy issues, institutions, or locations—suggests one of the significant challenges is aggregating generalizable evidence on LSA practices. Understanding these research needs represents a first step in advancing a global agenda for LSA research.
Optical deformation of single aerosol particles
Authors: Rafferty Aidan , Gorkowski Kyle , Zuend Andreas , Preston Thomas C. 
Published: September 2019

Significance
Optical tweezers have enabled an array of high-precision spectroscopic investigations into the physicochemical properties of atmospheric aerosol particles. The electromagnetic stress from the optical tweezers should deform the trapped particle, but this has previously been disregarded as a negligible effect. We demonstrate that nanometer-scale optical deformations on micron-sized aerosol particles are not always insignificant and can actually be measured using whispering gallery mode splitting. Interpretation of the optical spectrum of the deformed droplet is in itself fascinating as the proper explanation answers fundamental questions concerning optical trapping and how light interacts with matter, which we describe in detail. Furthermore, we present a methodology for contactless tensiometry measurements of single subpicoliter volume aqueous aerosol particles under both stable and metastable conditions.
Significance testing of the Altaic family
Authors: Ceolin Andrea 
Published: September 2019

AbstractHistorical linguists have been debating for decades about whether the classical comparative method provides sufficient evidence to consider Altaic languages as part of a single genetic unity, like Indo-European and Uralic, or whether the implicit statistical robustness behind regular sound correspondences is lacking in the case of Altaic. In this paper, I run a significance test on Swadesh-lists representing Turkish, Mongolian and Manchu to see if there are regular patterns of phonetic similarities or correspondences among word-initial phonemes in the basic vocabulary that cannot be expected to have arisen by chance. The methodology draws onOswalt (1970),Ringe (1992),Baxter & Manaster Ramer (2000)and Kessler (2001,2007). The results only partially point towards an Altaic family: Mongolian and Manchu show significant sound correspondences, while Turkish and Mongolian show some marginally significant phonological similarity, that might however be the consequence of areal contact. Crucially, Turkish and Manchu do not test positively under any condition.1
Borrowing from an unrelated language in support of intragenetic tendencies
Authors: Maisak Timur 
Published: September 2019

AbstractUdi is a Nakh-Daghestanian (Lezgic) language spoken in northern Azerbaijan, which has undergone many contact-induced changes due to the influence of unrelated languages of the eastern Caucasus (Indo-European, Turkic). A recent change is the borrowing of the conditional enclitic=safrom Azerbaijani (Turkic). In Udi, this marker can combine with finite indicative tenses, resulting in a series of derived ‘realis’ conditional mood forms. The clitic is also used to create an indefiniteness marker, which derives indefinite pronouns from interrogative ones. Prior to the borrowing of the Azerbaijani morpheme there was no comparable marker in Udi available to fulfil these functions, while other Lezgic languages employ their own native grammatical means for the same functions (conditional clitics or auxiliaries). The acquisition of the borrowed clitic has thus made Udi more and not less structurally isomorphic with respect to the other languages of the Lezgic branch. This paper develops a description of functions related to the domain of conditional mood on various stages of the history of Udi, and suggests a diachronic scenario for the borrowing of the Azerbaijani marker=sa.
