Published: October 2020

AbstractWe explore the potential and practical challenges in the use of artificial intelligence (AI) in cyber risk analytics, for improving organisational resilience and understanding cyber risk. The research is focused on identifying the role of AI in connected devices such as Internet of Things (IoT) devices. Through literature review, we identify wide ranging and creative methodologies for cyber analytics and explore the risks of deliberately influencing or disrupting behaviours to socio-technical systems. This resulted in the modelling of the connections and interdependencies between a system's edge components to both external and internal services and systems. We focus on proposals for models, infrastructures and frameworks of IoT systems found in both business reports and technical papers. We analyse this juxtaposition of related systems and technologies, in academic and industry papers published in the past 10 years. Then, we report the results of a qualitative empirical study that correlates the academic literature with key technological advances in connected devices. The work is based on grouping future and present techniques and presenting the results through a new conceptual framework. With the application of social science's grounded theory, the framework details a new process for a prototype of AI-enabled dynamic cyber risk analytics at the edge.

Abstract
Purpose
The objectives of this study are to provide the detailed information of designing, fabrication process, and performance test results of a surface acoustic wave (SAW) sensor for evaluating chicken meat storage time (up to 15 days).

Methods
The aldehyde gas generated from chicken meat was selected as the reactive material, and Love wave was used among various SAWs due to its high sensitivity of the aldehyde gas particles. The SAW sensor was fabricated on the surface of LiNbO3 piezoelectric wafer with a cross-linked polydimethylsiloxane (PDMS)-sensitive layer using standard photolithographic techniques. To analyze the fabricated SAW sensor characteristics, the S21 parameters and base line noise were acquired by a vector network analyzer. Before measuring chicken meat gas samples, a reference gas (a mixture of 25, 50, 75, and 100 ppm acetaldehyde (a functional group with the structure –CHO, CH3CHO) and nitrogen (N2) gas) was measured to verify the reactive performance of the SAW sensor. Among the VOCs from chicken meat gas, CH3CHO was selected as an intrinsic biomarker due to its harmful effects on the human body. Then, aldehyde gas from chicken meat samples was measured and the phase changes of the response signals with increasing the chicken meat storage time were obtained by the SAW sensor.

Results
About − 4 dB insertion loss occurred due to the PDMS coating and the high electromechanical coupling factor of used substrate. The phases of the response signals decreased linearly with increase of both the reference gas concentration and the storage time of the chicken meat samples. The determination coefficients of the reference gas and the storage time were over 0.9. The results show that the developed SAW sensor can provide valuable information about evaluating the chicken meat storage time.

Conclusion
The newly developed SAW sensor clearly demonstrates that chicken meat storage could be evaluated by detecting aldehyde gas. This opens a promising research avenue to explore.
The FaceChannel: A Fast and Furious Deep Neural Network for Facial Expression Recognition
Authors: Barros Pablo , Churamani Nikhil , Sciutti Alessandra 
Published: October 2020

AbstractCurrent state-of-the-art models for automatic facial expression recognition (FER) are based on very deep neural networks that are effective but rather expensive to train. Given the dynamic conditions of FER, this characteristic hinders such models of been used as a general affect recognition. In this paper, we address this problem by formalizing the FaceChannel, a light-weight neural network that has much fewer parameters than common deep neural networks. We introduce an inhibitory layer that helps to shape the learning of facial features in the last layer of the network and, thus, improving performance while reducing the number of trainable parameters. To evaluate our model, we perform a series of experiments on different benchmark datasets and demonstrate how the FaceChannel achieves a comparable, if not better, performance to the current state-of-the-art in FER. Our experiments include cross-dataset analysis, to estimate how our model behaves on different affective recognition conditions. We conclude our paper with an analysis of how FaceChannel learns and adapts the learned facial features towards the different datasets.
Maternal Serum VEGF Predicts Abnormally Invasive Placenta Better than NT-proBNP: a Multicenter Case-Control Study

Published: October 2020

AbstractThe aim of this study was to test if maternal serum vascular endothelial growth factor (VEGF) or N-terminal pro B-type natriuretic peptide (NT-proBNP) predicts abnormally invasive placenta (AIP) better. Secondary objective was to test whether the serum levels of VEGF and NT-proBNP can predict the degree of invasion. In a multicenter case–control study design, gestational age-matched serum samples from pregnant women with AIP (n = 44) and uncomplicated pregnancies (n = 55) who had been enrolled at Charité – Universitätsmedizin Berlin, Germany and Centre Hospitalier Régional de la Citadelle in Liège, Belgium were analyzed. Maternal blood serum VEGF and NT-proBNP levels were immunoassayed from samples taken immediately before delivery (GA median: 35 weeks). Biomarker levels were compared between AIP and control group. The correlation of biomarker levels with the clinical AIP degree was assessed. The predictive biomarker ability was characterized through a multivariate regression model and receiver operating characteristic curves. Women with AIP had significantly lower maternal serum VEGF levels (AIP mean 285 pg/ml, 95% CI 248–322, vs. control: 391 pg/ml, 95% CI 356–426, p < 0.01) and higher NT-proBNP levels (AIP median 329 pg/ml, IQR 287–385, vs. control 295 pg/ml, IQR 273–356, p = 0.03). Maternal serum VEGF levels were able to predict AIP better (AUC = 0.729, 0.622–0.836, p < 0.001; VEGF + number of previous cesarean deliveries: AUC = 0.915, 0.853–0.977, p < 0.001). Maternal serum VEGF levels correlated inversely with the clinical AIP degree (r = − 0.32, p < 0.01). In short, maternal serum VEGF, more than NT-proBNP, can help in predicting AIP and hints at the degree of invasion.

Published: October 2020

Abstract

Introduction
Providers may use several treatment options for patients with Peyronie’s disease; however, it is unclear whether practice patterns have evolved over recent years and if this has impacted cost.

Aims
To investigate trends in the treatment of Peyronie’s disease over time and the associated costs using a national, commercial insurance claims database.

Methods
A retrospective cohort study was conducted using claims from the Truven MarketScan database from 2007 to 2018 for men with Peyronie’s disease. Cost was estimated as either the sum of prescription oral or injectable treatment costs or as the single net cost associated with the operative procedure.

Main Outcome Measures
Frequency of use of various treatments for Peyronie’s disease and associated costs were assessed as trends over the timeline by year.

Results
The estimated annual incidence of Peyronie’s disease in this population rose from 61 to 77 per 100,000 patients over the included years, and the percent annual treatment rate rose from 17.8% to 26.2%. Colchicine was the most commonly prescribed oral agent in 2007 used in 22% of treated individuals; by 2018, pentoxifylline was the most common prescribed oral agent used in 33%. In 2007, 11% of treated patients received intralesional verapamil; however, by 2018, 24% received injectable collagenase, whereas &lt;1% received intralesional verapamil. The mean annual, per-individual cost of Peyronie’s disease treatment increased from $1,531 in 2007 to $10,339 in 2018. The cost increase was greatest for injectable therapies, which rose from $811 per individual in 2007 to $16,184 in 2018, a 19-fold increase.

Conclusions
Diagnosis and treatment of Peyronie’s disease is increasing over time. Pentoxifylline has become the most common oral prescription, whereas injectable collagenase has become most common injection. The mean cost associated with Peyronie’s disease treatment increased more than 5 times from 2007 to 2018 corresponding with Federal Drug Administration’s approval of injectable collagenase.

Abstract

Introduction
Infertility may negatively impact sexual function. Women with fertility problems usually prioritize treatment for infertility, but their sexual function in each trimester of pregnancy is poorly researched.

Aim
To compare the sexual function and sexual healthcare needs of women who underwent successful in vitro fertilization (IVF group) and women who conceived naturally (CN group) during each trimester.

Methods
Longitudinal prospective cohort study was conducted from August 2016 to July 2018. The IVF group (n = 100) was recruited from a leading reproductive treatment center; the CN group (n = 100), at the prenatal clinic of a medical center in central Taiwan. Questionnaires were mailed to women in the 10th–11th gestational week; 70 women in the IVF group and 75 in the CN group completed all 3 questionnaires, during the 10th–11th, 20th–21st, and 30th–31st gestational weeks.

Main Outcome Measures
Female Sexual Function Index and Nursing Intervention on Sexual Healthcare needs were compared between groups in each trimester.

Results
Most participants reported sexual dysfunction concerns during pregnancy. In the first trimester, the Female Sexual Function Index score was significantly lower in the IVF group than in the CN group (18.13 ± 6.27 vs 20.34 ± 5.87, respectively; P &lt; .05). Sexual healthcare needs at the permission level were significantly lower in the IVF group than in the CN group (10.78 ± 2.41 vs 11.79 ± 2.67, respectively; P &lt; .05).

Conclusion
The IVF group had lower sexual function in the first trimester than the CN group. Sexual function improved in the second trimester in the IVF group but decreased throughout pregnancy in the CN group. The CN group had a greater need for sexual healthcare nursing intervention at the permission level than the IVF group.
Is safe and effective LESS in benign adnexal diseases: A systematic review and meta-analysis
Authors: Pan Chunping , Zhao Renfeng , Jiang Yanming 
Published: October 2020

ABSTRACT

Objective:
This meta-analysis aimed to evaluate the safety and efficacy of laparoscopic single site surgery (LESS) versus conventional laparoscopy (CL) for benign adnexal diseases.

Method:
Databases, including PubMed, Cochrane, Web of Science and Embase were searched to identify all articles published up to February 2020. We calculated the odds ratios and weighted mean differences (WMDs) with 95% confidence intervals (CIs) for dichotomous and continuous data.

Results:
This study included 8 RCTs, 12 retrospective studies and 6 prospective studies with a total of 2658 patients. We found the LESS had a shorter length of hospital stay (WMD = −0.24 [−0.34, −0.13], I2 = 48.6%), lesser postoperative pain 24 after surgery (WMD = −0.28 [ −0.51, −0.05], I2 = 72.3%), lower analgesic consumption (WMD = 0.45 [0.33, 0.61], I2 = 46.9%), and better cosmetic outcomes than the CL group. A longer operative time (WMD = 0.18 [0.09, 0.28], I2 = 35.2%), higher rate of postoperative complications (OR = 1.93 [1.09, 3.40], I2 = 0.0%) was observed in the LESS group than in the CL group. Moreover, there was no significant difference in occurrence of wound infection, fever, ileus, estimated blood loss, intraoperative complications, and level of postoperative pain immediately, 6 h, 48 h after surgery between the LESS and CL groups.

Conclusion:
LESS may be safe and effective, option for the management of benign adnexal diseases. However, this novel technique has some disadvantages. Therefore, multicenter randomized controlled trials must be conducted to validate our findings.

Spread out random walks on homogeneous spaces
Authors: PROHASKA ROLAND 
Published: October 2020

AbstractA measure on a locally compact group is said to be spread out if one of its convolution powers is not singular with respect to Haar measure. Using Markov chain theory, we conduct a detailed analysis of random walks on homogeneous spaces with spread out increment distribution. For finite volume spaces, we arrive at a complete picture of the asymptotics of then-step distributions: they equidistribute towards Haar measure, often exponentially fast and locally uniformly in the starting position. In addition, many classical limit theorems are shown to hold. In the infinite volume case, we prove recurrence and a ratio limit theorem for symmetric spread out random walks on homogeneous spaces of at most quadratic growth. This settles one direction in a long-standing conjecture.
Uniform convergence rate for Birkhoff means of certain uniquely ergodic toral maps
Authors: KLEIN SILVIUS , LIU XIAO-CHUAN , MELO ALINE 
Published: October 2020

AbstractWe obtain estimates on the uniform convergence rate of the Birkhoff average of a continuous observable over torus translations and affine skew product toral transformations. The convergence rate depends explicitly on the modulus of continuity of the observable and on the arithmetic properties of the frequency defining the transformation. Furthermore, we show that for the one-dimensional torus translation, these estimates are nearly optimal.

Published: October 2020

AbstractAn observational study was conducted to characterize high-touch surfaces in emergency departments and hemodialysis facilities. Certain surfaces were touched with much greater frequency than others. A small number of surfaces accounted for the majority of touch episodes. Prioritizing disinfection of these surfaces may reduce pathogen transmission within healthcare environments.
Hopeful universalism
Authors: REA MICHAEL 
Published: October 2020

AbstractThis article argues against the rationality of ‘hopeful universalism’, the components of which include theunconditional considered hopethat soteriological universalism is true, and an absence of belief that it is true. Some proponents maintain that there is simply not enough evidence to affirm or deny universalism; others believe that it is probably false but nonetheless hope they are mistaken. This article argues that worshippers of God who maintain unconditional considered hope in the truth of universalism ought either to believe universalism or seek to abandon their hope in its truth, depending (in part) on how their confidence in the considerations that steer them away from universalism measure up against the beliefs that underwrite their hope in its truth. For such people, neither withholding belief in universalism nor believing that it is false while continuing to hope that it is true is a rational option.
Complexity, resources and text borrowing in state legislatures
Authors: Hansen Eric R. , Jansa Joshua M. 
Published: October 2020

AbstractDo states copy or reinvent language from complex policies as they diffuse, and does this depend on legislative resources? We argue that states will more frequently reinvent more complex policies, but that states with high-resource legislatures will reinvent more than their low-resource counterparts for more complex policies. We test the theory using the bill texts from 18 policies that diffused across the 50 states from 1983 to 2014, measuring reinvention and complexity using text analysis tools. In line with expectations, we find that complex policies are reinvented more than simple policies and that high-resource legislatures reinvent bills more than low-resource legislatures on average. However, we also find that low-resource legislatures reinvent complex policies at about the same rate as high-resource legislatures. The results indicate that even legislatures with limited resources work to adapt complex policies during the diffusion process.

AbstractObjective:Rapid right ventricular pacing during balloon aortic valvuloplasty is commonly used to achieve balloon stability in children and adults. There is no consensus for the use of the technique in neonates and infants. We sought to review our institutional experience with rapid right ventricular pacing-assisted balloon aortic valvuloplasty across all age groups and evaluate the safety and effectiveness of the technique in the sub-group of neonates and infants <12months.Methods:Retrospective study between February, 2011 and February, 2020.Results:A total of 37 patients (Group I: 21 neonates/infants <12months and Group II: 16 children 12 months–16 years) were analysed. Catheter-measured left ventricular to aortic gradient reduced from median of 66 mmHg (with a range from 30 to 125 mmHg) to 14 mmHg (with a range from 5 to 44 mmHg) in Group I and 44 mmHg (with a range from 28 to 93 mmHg) to 18 mmHg (with a range from 2 to 65 mmHg) in Group II (p < 0.001). Procedure and fluoroscopy times were identical in the two groups. Balloon:annulus ratio was 0.94 and 0.88 in Groups I and II, respectively. Freedom from reintervention was 100% for Group I at a median time of 3.2 years and 81% at 2.7 years for Group II. Reinterventions in Group II (3/16 pts) were performed predominantly for complex left ventricular outflow tract stenosis. At follow-up echocardiogram, 45% of patients in Group I had no aortic regurgitation, 30% trace-mild, 20% mild-moderate, and 5% moderate aortic regurgitation, whereas in Group II, 50% of patients had no aortic regurgitation, 32% had mild aortic regurgitation, and 18% mild-moderate aortic regurgitation. Unicuspid valves were only encountered in Group 1 (2/21 pts, 10%) and they were predictive of mild-aortic regurgitation during follow-up (p = 0.003). Ventricular fibrillation occurred in three neonates with suspicion of myocardial ischemia on the pre-procedure echocardiogram. All were successfully defibrillated.Conclusions:Rapid right ventricular pacing can be expanded in neonates and infants to potentially decrease the incidence of aortic regurgitation and reintervention rates, hence avoiding high-risk surgical bail-out procedures for severe aortic regurgitation in the first year of life. Myocardial ischemia may predispose to ventricular dysrhythmias during rapid right ventricular pacing.
Deep Tectonics in the Eastern Hellenides Uncovered: The Record of Variscan Continental Amalgamation, Permo‐Triassic Rifting, and Early Alpine Collision in Pre‐Variscan Continental Crust in the W‐Rhodope (Vertiscos‐Ograzden Complex, N‐Greece)
Authors: Mposkos Evripidis , Krohe Alexander , Baziotis Ioannis 
Published: October 2020

AbstractThe Vertiskos‐Ograzden metamorphic complex (VOC; W‐Rhodope Metamorphic Domain, RMD) is a key area for reconstructing the geodynamic history of the Hellenides. We distinguish four metamorphic events: (1) an (U)HP eclogite facies metamorphism, succeeded by partial melting during decompression, amphibolite facies reequilibration in the kyanite stability field, and injection of muscovite pegmatites; (2) a LP‐HT event, associated with partial melting within the stability field of sillimanite, cordierite, and K‐feldspar (andalusite at subsolidus conditions) and magmatic intrusions; (3) a prograde moderate high‐pressure (MHP) metamorphism within the kyanite stability field increasing to the NE from epidote amphibolite to upper amphibolite facies; and (4) in the easternmost VOC, a LP amphibolite facies event (new cordierite and andalusite). Considering existing geochronological data, the VOC formed part of successive tectonic settings: (1) the “Variscan” collision zone between “East‐Avalonian” and Armorican continental fragments; (2) the Triassic middle crust of a continental rift zone, (leading to formation of oceanic crust, in the eastern VOC); (3) late Jurassic‐early Cretaceous closure of the oceanic basin and accretion of the VOC to southern European margin and northeastward polarity of subduction/collision; (4) late Cretaceous extension and crustal thinning. Then, subduction of the Neo‐Tethys and Apulian plate underneath Europe occurred, and the VOC plus the upper units of the RMD were part of the upper (European) plate. Large‐scale north dipping low‐angle normal detachments exhumed the VOC from the vicinity of a magmatic arc presently situated in the north RMD and Sredna Gora and Strandja zones and drag it into its present position.
Spreadsheet Tools for Quantifying Seepage Flux Across the GW‐SW Interface
Authors: Ford R. G. , Lien B. K. , Acree S. D. , Ross R. R. 
Published: October 2020

AbstractIdentifying the spatial distribution and magnitude of seepage flux across the groundwater‐surface water (GW‐SW) interface is critical for assessing potential impairments and restoration alternatives for water bodies adjacent to sites with groundwater contamination. Measurement of the vertical distribution and time‐varying characteristics of temperature in sediments provides an indirect way to map out spatial and temporal patterns of seepage flux into surface water. Two spreadsheet‐based calculation tools are introduced that implement four one‐dimensional analytical solutions to calculate the magnitude and direction of seepage flux based on measurement of steady‐state vertical temperature profiles or transient diel temperature signals at two depths within sediment. Performance of these calculation tools is demonstrated for a pond receiving contaminated groundwater discharge from an adjacent landfill. Transient versus steady‐state model performance is compared, and limitations of transient models are illustrated for a situation with unfavorable sediment characteristics and inadequate sensor spacing. The availability of a range of analytical solutions implemented within Microsoft Excel® is intended to encourage practitioners to explore use of this seepage flux characterization method and develop greater insight into best practices for model selection and use.
