Algorithm development for the spool installation sequence of outfitting works in offshore structure
Authors: Choi Jae Ho , Woo Jong Hun 
Published: July 2020

AbstractIn the early 2000s, shipyards in South Korea were the most competitive in the world for commercial vessels because of their accumulated production and quality management capabilities. In the mid-2000s, the rising trend of international oil prices and predicted market growth of offshore structures caused large shipyards in South Korea to start focusing on the construction of offshore structures. However, these shipyards suffered massive losses because they did not properly reflect the characteristics of offshore structures, which differ from those of commercial vessels. Such losses can largely be classified into engineering losses and production losses. This study aimed to address problems related to outfitting installation work from a production perspective. An algorithm was developed to define an efficient spool installation sequence and was verified through actual data of offshore structure. The developed algorithm should make it possible to plan spool installation work by determining an efficient spool installation sequence. In addition, the algorithm can assist in prompt decision making and eliminate wasted cost and time by providing with an efficient spool installation sequence.

AbstractTo investigate the performance of a deep learning-based algorithm for fully automated quantification of left ventricular (LV) volumes and function in cardiac MRI. We retrospectively analysed MR examinations of 50 patients (74% men, median age 57 years). The most common indications were known or suspected ischemic heart disease, cardiomyopathies or myocarditis. Fully automated analysis of LV volumes and function was performed using a deep learning-based algorithm. The analysis was subsequently corrected by a senior cardiovascular radiologist. Manual volumetric analysis was performed by two radiology trainees. Volumetric results were compared using Bland–Altman statistics and intra-class correlation coefficient. The frequency of clinically relevant differences was analysed using re-classification rates. The fully automated volumetric analysis was completed in a median of 8 s. With expert review and corrections, the analysis required a median of 110 s. Median time required for manual analysis was 3.5 min for a cardiovascular imaging fellow and 9 min for a radiology resident (p < 0.0001 for all comparisons). The correlation between fully automated results and expert-corrected results was very strong with intra-class correlation coefficients of 0.998 for end-diastolic volume, 0.997 for end-systolic volume, 0.899 for stroke volume, 0.972 for ejection fraction and 0.991 for myocardial mass (all p < 0.001). Clinically meaningful differences between fully automated and expert corrected results occurred in 18% of cases, comparable to the rate between the two manual readers (20%). Deep learning-based fully automated analysis of LV volumes and function is feasible, time-efficient and highly accurate. Clinically relevant corrections are required in a minority of cases.
Borders as Mirrors: Racial Hierarchies and Policing Migration
Authors: Parmar Alpa 
Published: July 2020

AbstractThis article considers how state-controlled borders and bordering practices are conceptualized, what they symbolize, and the consequences of these representations. By analyzing critically the metaphors that are used to describe borders and migration, and by drawing on empirical research on policing migration in the United Kingdom, an alternative metaphor, where borders are depicted heuristically as mirrors, may be instructive for capturing the multiple functions of borders and their racializing consequences. I propose that borders and their control across Western liberal democracies are like mirrors that represent, reflect and, at times, deflect the reality of exclusionary attitudes and the racialized anxieties they foment. Harnessing the function of borders through a process of self-reflection, where societies hold a mirror to themselves, may be both instructive and transformative. By reconsidering the metaphors employed in relation to migration, the article contributes to interdisciplinary debates on border studies, critical race perspectives and the criminalization of mobility.

Published: July 2020

AbstractThe International Society for Clinical Electrophysiology of Vision (ISCEV) standard for visual evoked potentials (VEPs) describes a minimum procedure for clinical VEP testing and encourages more extensive testing. This ISCEV extended protocol is an extension to the VEP standard. It describes procedures for recording multiple VEPs to a range of sizes of pattern stimuli to establish the VEP spatial frequency limit (threshold) and for relating this limit to visual acuity.
Investigating Coupled Effect of Radiative Heat Flux and Firebrand Showers on Ignition of Fuel Beds
Authors: Suzuki Sayaka , Manzello Samuel L. 
Published: July 2020

AbstractFire spread occurs via radiation, flame contact, and firebrands. While firebrand showers are known to be a cause of spot fires which ignite fuels far from the main fire front, in the case of short distance spot fires, radiation from the main fire may play a role for firebrand induced ignition processes. Many past investigations have focused on singular effects on fire spread, and little is known about coupled effects. The coupled effect of radiative heat flux and firebrand showers on ignition processes of fuel beds is studied by using a newly developed experimental protocol. The newly developed protocol includes the addition of a radiant panel to the existing experimental setup of a firebrand generator coupled to a wind facility. Experiments were performed under an applied wind field, as the wind is a key parameter in large outdoor fire spread processes. Results show that radiant heat flux plays an important role for ignition by firebrands under 6 m/s while little effect was observed under 8 m/s.
CoCon: A Conference Management System with Formally Verified Document Confidentiality
Authors: Popescu Andrei , Lammich Peter , Hou Ping 
Published: July 2020

AbstractWe present a case study in formally verified security for realistic systems: the information flow security verification of the functional kernel of a web application, the CoCon conference management system. We use the Isabelle theorem prover to specify and verify fine-grained confidentiality properties, as well as complementary safety and “traceback” properties. The challenges posed by this development in terms of expressiveness have led to bounded-deducibility security, a novel security model and verification method generally applicable to systems describable as input/output automata.
Men Lose Life Satisfaction with Fewer Hours in Employment: Mothers Do Not Profit from Longer Employment—Evidence from Eight Panels
Authors: Schröder Martin 
Published: July 2020

AbstractThis article uses random and fixed effects regressions with 743,788 observations from panels of East and West Germany, the UK, Australia, South Korea, Russia, Switzerland and the United States. It shows how the life satisfaction of men and especially fathers in these countries increases steeply with paid working hours. In contrast, the life satisfaction of childless women is less related to long working hours, while the life satisfaction of mothers hardly depends on working hours at all. In addition, women and especially mothers are more satisfied with life when their male partners work longer, while the life satisfaction of men hardly depend on their female partners’ work hours. These differences between men and women are starker where gender attitudes are more traditional. They cannot be explained through differences in income, occupations, partner characteristics, period or cohort effects. These results contradict role expansionist theory, which suggests that men and women profit similarly from moderate work hours; they support role conflict theory, which claims that men are most satisfied with longer and women with shorter work hours.

Published: July 2020

AbstractEcology and epidemiology of Echinococcus multilocularis and human alveolar echinococcosis (AE) are changing in Central Europe. Our data from a regional referral center for AE in southwest Germany suggest rising regional incidence for AE (annual incidence per 100,000 population 2004–2011: 0.12; 2012–2019: 0.20) and emerging urban AE (of 7 cases of AE in Freiburg city dwellers none was diagnosed before 2012) calling for an intensification of E. multilocularis and AE surveillance and of AE prevention measures.

AbstractThe pervasive problem of irreproducibility of preclinical research represents a substantial threat to the translation of CTSA-generated health interventions. Key stakeholders in the research process have proposed solutions to this challenge to encourage research practices that improve reproducibility. However, these proposals have had minimal impact, because they either 1. take place too late in the research process, 2. focus exclusively on theproductsof research instead of theprocessesof research, and/or 3. fail to take into account the driving incentives in the research enterprise. Because so much clinical and translational science is team-based, CTSA hubs have a unique opportunity to leverage Science of Team Science research to implement and support innovative, evidence-based, team-focused, reproducibility-enhancing activities at a project’s start, and across its evolution. Here, we describe the impact of irreproducibility on clinical and translational science, review its origins, and then describe stakeholders’ efforts to impact reproducibility, and why those efforts may not have the desired effect. Based on team-science best practices and principles of scientific integrity, we then propose ways for Translational Teams to build reproducible behaviors. We end with suggestions for how CTSAs can leverageteam-basedbest practices and identify observable behaviors that indicate a culture of reproducible research.
Tails of exit times from unstable equilibria on the line
Authors: Bakhtin Yuri , Pajor-Gyulai Zsolt 
Published: July 2020

AbstractFor a one-dimensional smooth vector field in a neighborhood of an unstable equilibrium, we consider the associated dynamics perturbed by small noise. We give a revealing elementary proof of a result proved earlier using heavy machinery from Malliavin calculus. In particular, we obtain precise vanishing noise asymptotics for the tail of the exit time and for the exit distribution conditioned on atypically long exits. We also discuss our program on rare transitions in noisy heteroclinic networks.
On the extension of signature-based representations for coherent systems with dependent non-exchangeable components
Authors: Navarro Jorge , Fernández-Sánchez Juan 
Published: July 2020

AbstractThe signature representation shows that the reliability of the system is a mixture of the reliability functions of the k-out-of-n systems. The first representation was obtained for systems with independent and identically distributed (IID) components and after it was extended to exchangeable (EXC) components. The purpose of the present paper is to extend it to the class of systems with identically distributed (ID) components which have a diagonal-dependent copula. We prove that this class is much larger than the class with EXC components. This extension is used to compare systems with non-EXC components.
Randomized near-neighbor graphs, giant components and applications in data science
Authors: Jaffe Ariel , Kluger Yuval , Linderman George C. , Mishne Gal , Steinerberger Stefan 
Published: July 2020

AbstractIf we picknrandom points uniformly in$[0,1]^d$and connect each point to its$c_d \log{n}$nearest neighbors, where$d\ge 2$is the dimension and$c_d$is a constant depending on the dimension, then it is well known that the graph is connected with high probability. We prove that it suffices to connect every point to$ c_{d,1} \log{\log{n}}$points chosen randomly among its$ c_{d,2} \log{n}$nearest neighbors to ensure a giant component of size$n - o(n)$with high probability. This construction yields a much sparser random graph with$\sim n \log\log{n}$instead of$\sim n \log{n}$edges that has comparable connectivity properties. This result has non-trivial implications for problems in data science where an affinity matrix is constructed: instead of connecting each point to itsknearest neighbors, one can often pick$k'\ll k$random points out of theknearest neighbors and only connect to those without sacrificing quality of results. This approach can simplify and accelerate computation; we illustrate this with experimental results in spectral clustering of large-scale datasets.
The Bolsonaro Voter: Issue Positions and Vote Choice in the 2018 Brazilian Presidential Elections
Authors: Rennó Lucio R. 
Published: July 2020

ABSTRACTThe 2018 Brazilian elections saw the rise to power of Jair Bolsonaro, yet another conservative politician who won an election in recent years. What were the ideological underpinnings of the Bolsonaro vote? Was his support based exclusively on resentment toward the Workers’ Party? This article uses a unique public opinion dataset, the 2018 Brazilian Electoral Panel Study, to explore how positions on divisive issues related to social, political, and cultural factors influenced vote choice andBolsonarismo—affection toward Bolsonaro supporters—in the 2018 Brazilian presidential elections. Results indicate that in addition to resentment against the Workers’ Party, a cultural backlash perspective, and strict views on law and order, as well as economic liberalism and rejection of social policies, were the characteristics of support for Bolsonaro.
The logistics of the Republic of Letters: mercantile undercurrents of early modern scholarly knowledge circulation
Authors: ORRJE JACOB 
Published: July 2020

AbstractAnglo-Swedish scholarly correspondence from the mid-eighteenth century contains repeated mentions of two merchants, Abraham Spalding and Gustavus Brander. The letters describe how these men facilitated the exchange of knowledge over the Baltic Sea and the North Sea by shipping letters, books and other scientific objects, as well as by enabling long-distance financial transactions. Through the case of Spalding and Brander, this article examines the material basis for early modern scholarly exchange. Using the concept of logistics to highlight and relate several mercantile practices, it examines ways of making scholarly knowledge move, and analyses merchants’ potential motives for offering their services to scholarly communities. As logisticians in the Republic of Letters, these merchants could turn their commercial infrastructure into a generator of cultural status valid in both London and Stockholm. Using mercantile services, scholarly knowledge could in turn traverse the region in reliable, cost-effective and secure ways. The case of Spalding and Brander thus highlights how contacts between scholarly communities intersected with other contemporary modes of transnational exchange, and it shows how scholarly exchange relied on relationships based on norms different from the communalism often used to characterize the early modern Republic of Letters. Thus the article suggests new ways of studying early modern scholarly exchange in practice.

AbstractObjectiveCerebrospinal fluid rhinorrhoea takes place when there is a breakdown of the barriers separating the nasal cavity from the subarachnoid space. The aim of this study was to assess the surgical outcomes of endoscopic transnasal cerebrospinal fluid leak repair with and without fibrin glue.MethodThere were 43 patients with cerebrospinal fluid rhinorrhoea who underwent surgery for cerebrospinal fluid leak repair between 2014 and 2018. Patients were divided into group A, where fibrin glue was used, and group B, where fibrin glue was not used.ResultsIt was found that 74.4 per cent of cases were due to spontaneous cerebrospinal fluid leak. The most common site of a leak was the cribriform plate (65 per cent). There was a success rate of 96.1 per cent (25 of 26) in group A and 83 per cent (15 of 17) in group B. There was no statistically significant difference between the results of the two groups (chi-square test: p = 0.31).ConclusionThere was no statistically significant difference in the results of cerebrospinal fluid leak repair with and without fibrin glue.

AbstractStarch content is an important trait in barley. To evaluate the genetic diversity and identify molecular markers of starch content in barley, 40 cultivated barley genotypes collected from different regions, including genotypes whose starch content is at either the high or low end of the spectrum (15), were used in this study. All the genotypes were re-sequenced by the double-digest-restriction associated DNA sequencing method, and a total of 299,103 single-nucleotide polymorphism (SNP) markers were obtained. The genotypes were divided into four sub-populations based on FASTSTRUCTURE, principal component analysis and neighbour-joining tree analysis. All four sub-populations had a high linkage disequilibrium, especially group 3, whose members were recently bred for malting in the Jiangsu coastal area. The starch content of the barley lines was evaluated during three growing seasons (2014–2017), and the average values of starch content across the three growing seasons at the low and high ends were 51.5 and 55.0%, respectively. The starch content was affected by population structure, the barley in group 2 had a low starch content, while the barley in group 4 had a high starch content. Twenty-six SNP markers were identified as being significantly associated with starch content (P ⩽ 0.001) based on the average values across the three growing seasons using the mixed linear model method. These SNP markers were located on chromosomes 1H and 4H, and were considered loci of qSC1-1 and qSC4-1, respectively. The major identified QTLs for starch content are helpful for further research on carbohydrates and for barley breeding.
Dielectric sensitivity of different antennas types for microwave-based head imaging: numerical study and experimental verification
Authors: Tesarik Jan , Pokorny Tomas , Vrba Jan 
Published: July 2020

AbstractThe design of proper antenna element (AE) for microwave-based head imaging or brain stroke detection is a crucial challenge in the development process of microwave imaging (MWI) systems. The main purpose of this paper was to design, fabricate, and experimentally verify the compact and dimensions-reduced H-slot antenna suitable for the new generation of multichannel MWI system for brain stroke detection. The slot antenna type was chosen based on the numerical study of three AEs available in the literature, i.e. bow tie, slot, and waveguide-based. The study was focused on the sensitivity of the antennae (change of magnitude and phase ofS21) due to dielectric parameters change or type and diameter of inclusion in a head phantom representing a hemorrhagic (HEM) or ischemic (ISCH) stroke phantom, respectively. Further, the analysis of antenna radiation to lossy medium/air and its immunity against plane wave exposure was carried out. The H-slot antenna was fabricated and experimentally verified (measurements of reflection as well as transmission coefficients) using a liquid head phantom with inserted HEM stroke phantom (both prepared as a mixture of propylene glycol, water, and salt). The phantoms were filled inside the designed two-port test system. Numerical models were validated by comparing calculated and measuredS-parameters. The sensitivity of the H-slot antenna to the presence of the HEM stroke phenomenon within the phantom of the head was also demonstrated. The main advantage of the proposed H-slot antenna is its small dimensions, easy, inexpensive, and repeatable fabrication as well as mechanical stability.

AbstractDiet has important effects on normal physiology and the potential deleterious effects of high fat diets and obesity on male reproductive health are being increasingly described. We conducted a histological review of the effects of chronic high fat (HF) diet (using a mouse model fed a 45% fat diet for 21 weeks) with a discovery proteomic study to assess for changes in the abundance of proteins in the testis. Mice on a HF diet became obese and developed glucose intolerance. Using mass spectrometry, we identify 102 proteins affected in the testis of obese mice. These included structural proteins important for the blood testis barrier (filamin A, FLNA), proteins involved in oxidative stress responses (spermatogenesis associated 20, SPATA-20) and lipid homoeostasis (sterol regulatory element-binding protein 2, SREBP2 and apolipoprotein A1, APOA1). In addition, an important regulator protein paraspeckle component 1, PSPC-1, which interacts with the androgen receptor was significantly downregulated. Proteomic data was validated using both Western blotting and immunostaining which confirmed and localised protein expression in both mouse and human testis using biopsy specimens. This study focused mainly on the abnormalities that occurred at the protein level and as a result, we have identified several candidate proteins and conducted pathway analysis around the effects of HF diet on the testis providing novel insights not previously described. Some of the identified targets could be targeted therapeutically and future work is directed in this area.
